Abstract

<P>PROBLEM TO BE SOLVED: To provide an air purifier that can expel mist outside vigorously. <P>SOLUTION: A guide rib 24 is installed in a rear fan casing 17B. A part of air that tends to flow to a second discharge port 22 in the rear fan casing 17B is branched to a ventilation port 57 side with the guide rib 24. As a result, by this branched air, the air for the purpose of expelling outside an electrolytic water mist generated in an electrolytic water mist generating unit 30 can be secured to a comparatively large quantity. Also, by branching the air flowing inside the rear fan casing 17B with the guide rib 24, the flow rate of the air can be increased that is branched to the electrolytic water mist generating unit 30 side. Consequently, the electrolytic water mist can be vigorously expelled outside by means of this branched air. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to an air cleaner.

There is known an air cleaner that takes in air, purifies the air, and discharges the air to the outside. For example, when the air taken into the machine passes through a filter, dust contained in the air is removed. And the air cleaner with which the electrolyzed water mist generator was equipped is proposed (refer patent document 1). The electrolyzed water mist generator generates electrolyzed water by electrolyzing tap water, etc. stored inside, generates mist (electrolyzed water mist) from the electrolyzed water, and cleans the air with an air cleaner. Disperse to the outside with mist. Thereby, air can be sterilized or deodorized with mist.
JP 2007-37589 A

  In the air cleaner disclosed in Patent Document 1, the cleaned air is discharged to the outside mainly through an outlet provided in the air cleaner, and a vent hole provided separately from the outlet is provided. Also passed through the electrolyzed water mist generator. The air supplied to the electrolyzed water mist generator is dissipated to the outside through the radiation outlet with the mist generated by the electrolyzed water mist generator.

  Here, when the amount of mist generated is increased, the flow velocity of the air carrying the mist is reduced. Thereby, the mist that has reached the diffusion port by riding on air is not diffused from the diffusion port vigorously and stays around the diffusion port, and there is a risk that condensation occurs around the diffusion port. Then, when the moisture that causes dew condensation is dried, calcium contained in the moisture is deposited and becomes dirty around the outlet, which may impair the appearance of the air cleaner.

The present invention has been made based on such a background, and a main object thereof is to provide an air purifier capable of vigorously releasing mist to the outside.
Another object of the present invention is to provide an air purifier that can stably supply purified air.

  The invention according to claim 1 is an air cleaning means for purifying air passing therethrough, an air blowing means for sending air so that air enters from the inlet, passes through the air cleaning means and exits from the outlet, And an air cleaner including an electrolyzed water mist generating unit for dissipating electrolyzed water mist using the purified air after passing through the air cleaning means, and cleaning after passing through the air cleaning means A ventilation path for guiding the converted air to the outlet, and in order to divert a part of the air flowing through the ventilation path to the electrolyzed water mist generating unit instead of the outlet, The air purifier is characterized in that a guide rib having a predetermined length extending along the flow direction of the air flowing through the ventilation path is provided.

  According to a second aspect of the present invention, the guide rib has the ventilation path completely divided into the outlet side and the electrolyzed water mist generating unit side on the downstream side when viewed in the air flow direction, and the upstream side is the ventilation path. A part of the path is divided into the outlet side and the electrolyzed water mist generating unit side, and a part of the air flowing to the electrolyzed water mist generating unit side returns to the outlet side on the upstream side when viewed in the air flow direction. The air purifier according to claim 1, wherein the air purifier has a shape to be obtained.

  According to the first aspect of the present invention, in this air purifier, a part of the air flowing through the ventilation path after being purified by passing through the air cleaning means is diverted to the electrolyzed water mist generating unit side by the guide rib. The Therefore, a relatively large amount of air for diffusing the electrolyzed water mist generated by the electrolyzed water mist generating unit to the outside can be secured by the diverted air. And the flow velocity of the air shunted to the electrolyzed water mist generating unit side can be increased by diverting the air flowing through the ventilation path by the guide rib. As a result, the electrolyzed water mist can be vigorously diffused to the outside by the diverted air.

  According to the second aspect of the present invention, a part of the air diverted to the electrolyzed water mist generating unit side by the guide rib can return to the outlet side upstream of the guide rib in the air flow direction. Therefore, in this air purifier, it is possible to prevent the flow of air flowing out from the outlet from being reduced by diverting more air than necessary in the air flowing through the ventilation path to the electrolyzed water mist generating unit side, and purifying air The amount of outflow at the outlet can be secured stably. That is, by providing such guide ribs, the electrolyzed water mist can be diffused to the outside vigorously, and the original function of the air cleaner (stable supply of purified air) can be ensured.

Below, with reference to drawings, the air cleaner as one embodiment of this invention is explained concretely.

FIG. 1 is a perspective view of the air purifier 1 as seen from the front upper right side, and shows a state in which the front decorative panel 5 is shifted to the front side. FIG. 2 is a vertical cross-sectional view of the substantially central portion of the air cleaner 1. FIG. 3 is a cross-sectional view based on the line AA in FIG. 4 is a cross-sectional view based on the line BB in FIG. 5A and 5B are cross-sectional views based on the line C-C in FIG. 2, in which FIG. 5A shows the first form, and FIG. 5B shows the second form. 6A and 6B show the shape of the guide rib 24. FIG. 6A shows the shape used in the first form shown in FIG. 5A, and FIG. 6B shows the second shape shown in FIG. The shape used by a form is shown.

First, regarding the attitude of the air purifier 1, in FIG. 2, the vertical direction of the paper surface is the vertical direction (height direction), the horizontal direction of the paper surface is the front-back direction, and the thickness direction of the paper surface is the horizontal direction (width direction). Such definition of direction is also applied to other drawings.
As shown in FIG. 1, the main body case 2 of the air cleaner 1 has a substantially rectangular parallelepiped shape that is vertically long and thin in the front-rear direction. The main body case 2 has an outer case formed by a rear case 3, a main frame 4, and a front decorative panel 5. The rear case 3 forms a bottom surface, a rear surface, a rear portion on the left and right side surfaces, and a rear portion on the upper surface in the main body case 2. The main frame 4 is disposed adjacent to the front side of the rear case 3, and forms a front part on the left and right side surfaces and a front part on the upper surface in the main body case 2. The main frame 4 is longer than the rear case 3. The front decorative panel 5 covers the front surface of the main frame 4 from the front side, and forms a front surface in the main body case 2.

  As shown in FIG. 2, the inside of the main body case 2 is divided forward and backward by a partition plate 6 extending in the vertical and horizontal directions. In the main body case 2, a blower 7 (blower unit) is disposed in a rear space (referred to as a rear space 25) partitioned by the partition plate 6. The blower 7 includes a motor 8 and a sirocco fan 9 that is rotationally driven by the motor 8. The motor 8 is attached to the partition plate 6. A number of communication holes 10 are formed around the motor 8 of the partition plate 6 so as to communicate the front and rear of the partition plate 6.

  In the main body case 2, a filter 11 (air cleaning means) is disposed in a front space (referred to as a front space 26) partitioned by the partition plate 6. The filter 11 includes a coarse pre-filter 12, a main filter 13 that captures fine dust, and a deodorizing filter 14 made of activated carbon particles such as zeolite that adsorbs odorous components. The filter 13 and the deodorizing filter 14 are arranged in this order. The pre-filter 12 is a thin net-like filter having a rectangular shape that is long in the vertical direction, and is for capturing relatively large dust contained in the air. The main filter 13 has a configuration in which, for example, a nonwoven fabric is folded into a pleat shape, and is a filter that can capture very fine dust in the air, such as pollen and tobacco smoke particles. Details of the filter 11 will be described later.

As shown in FIG. 3, air inlets 15 (inlet ports) are provided in front portions of the left and right side surfaces of the main body case 2 (left and right side surfaces of the main frame 4). A lattice-like louver 16 is attached to the intake port 15. The air inlet 15 communicates with the space between the pre-filter 12 and the front decorative panel 5, that is, the windward side of the filter 11.
In the rear space 25, the fan 7 is disposed, and a fan casing 17 surrounding the sirocco fan 9 is formed. The fan casing 17 is divided forward and backward by a partition plate 4A that is formed integrally with the main frame 4 and extends in the vertical and horizontal directions. That is, the partition plate 4A partitions the fan casing 17 forward and backward so as to bisect each blade 9A of the sirocco fan 9 in the axial direction (front-rear direction).

  As shown in FIGS. 2 and 4, the front fan casing 17A, which is a front side portion of the fan casing 17 partitioned by the partition plate 4A, has a spiral rib 4B in front view protruding from the partition plate 4A to the front side, It is formed by the partition plate 6 and the partition plate 4A. As shown in FIG. 4, first discharge ports 18 are formed at the left and right ends of the front fan casing 17 </ b> A, respectively. The left and right first discharge ports 18 are respectively connected to first discharge ports 19 opened on the left and right side surfaces of the rear case 3. A lattice-shaped first air guide 20 is attached to each first discharge port 19.

  As shown in FIG. 5A, a rear fan casing 17B (ventilation path), which is a rear side portion of the fan casing 17 partitioned by the partition plate 4A, is projected from the rear case 3 to the front side. A b-shaped rib 3B, a partition plate 4A (see FIG. 3), and a rear side wall of the rear case 3 are formed. A second discharge port 21 is provided at the upper end of the rear fan casing 17B. The second discharge port 21 is connected to a second discharge port 22 (exit) opened on the upper surface of the rear case 3. A lattice-shaped second air guide 23 formed integrally with the rear case 3 is disposed at the second discharge port 22.

  In such an air purifier 1, when the blower 7 is driven, as shown by the solid line arrows in FIG. By sucking and passing through the pre-filter 12, the main filter 13, and the deodorizing filter 14, dust and odor components are removed and cleaned. Cleaned air (hereinafter, simply referred to as “air”) is guided to the fan casing 17 in the rear space 25 through the communication hole 10 by the rotating sirocco fan 9.

  In the fan casing 17, the air guided to the front fan casing 17 </ b> A is sent from the left and right first discharge ports 18 to the first air guide 20 and the first air guide 20 by the rotating sirocco fan 9, as shown by broken arrows in FIGS. 3 and 4. It is discharged from the left and right side surfaces of the main body case 2 through the one discharge port 19. As described above, the front fan casing 17 </ b> A has a function as a ventilation path for guiding the air guided to the front fan casing 17 </ b> A to the first discharge port 19.

  On the other hand, the air guided to the rear fan casing 17B in the fan casing 17 is moved upward by the rotating sirocco fan 9 as shown by the broken arrow in FIG. 2 and FIG. It is discharged from the upper surface of the main body case 2 to the outside through the guide 23 and the second discharge port 22. As described above, the rear fan casing 17 </ b> B has a function as a ventilation path for guiding the air guided to the rear fan casing 17 </ b> B to the second discharge port 22.

In this way, the purified air is discharged from the three directions of the left and right side surfaces and the upper surface of the main body case 2, so that the air can be distributed well to every corner of the room and the entire room can be purified evenly.
Below, each element in the air cleaner 1 is demonstrated.
<Guide rib>
As shown in FIG. 2, a pipe (referred to as an air guide pipe 56) that protrudes forward is provided above the partition plate 4 </ b> A. The inside of the air guide pipe 56 communicates with the rear fan casing 17B behind the partition plate 4A. An opening (referred to as a vent 57 as a supply port) that communicates with the inside of the air guide tube 56 is formed at the front end of the air guide tube 56. The vent 57 faces one end opening 42B of the electrolyzed water mist generating unit 30 described later.

  As shown in FIG. 5A, a guide rib 24 that protrudes forward from the rear case 3 is provided in the vicinity of the second discharge port 21 at the left end of the rear fan casing 17B. The guide rib 24 extends substantially along the flow direction of the air flowing through the rear fan casing 17B, and when viewed from the width direction, the guide rib 24 has an I shape, that is, a rectangular plate shape that is long in the vertical direction (FIG. 6A). reference). In the rear fan casing 17B, the guide rib 24 completely divides the downstream region in the air flow direction into the vent 57 (air guide pipe 56) side and the second discharge port 21 side. Therefore, a part of the air that tends to flow in the rear fan casing 17B along the broken arrow in FIG. 5A toward the second discharge port 22 is not the second discharge port 22 but the guide rib 24. The air is diverted to the vent 57 (electrolyzed water mist generating unit 30) side (see the dashed line arrow in FIG. 5A). The length of the guide rib 24 in the vertical direction is appropriately set according to how much air flowing in the rear fan casing 17B is diverted to the vent 57 side. When the I-shaped guide rib 24 is employed, a certain amount of airflow can be reliably supplied to the vent 57 side, and the electrolyzed water mist generating unit 30 described later can function properly.

The shape of the guide rib 24 may be an L shape shown in FIG. 6B other than the I shape shown in FIG. That is, a part of the guide rib 24 shown in FIG. 6B is notched on the upstream side in the air flow direction in the rear fan casing 17B. Referring to FIG. 5 (b), the L-shaped guide rib 24 is located on the downstream side of the rear fan casing 17B on the downstream side of the ventilation fan 57 side and the second discharge port as viewed in the air flow direction. It is completely separated from the exit 21 side. On the other hand, the L-shaped guide rib 24 partially divides the downstream region of the rear fan casing 17B into the ventilation port 57 side and the second discharge port 21 side on the upstream side. Therefore, on the upstream side of the L-shaped guide rib 24, a part of the air flowing to the vent 57 side passes through the notch portion of the guide rib 24 described above (see reference numeral 24A in FIG. 6B). It can return to the 2 discharge port 21 (2nd discharge port 22) side (refer the dashed-two dotted line arrow of FIG.5 (b)). When the L-shaped guide rib 24 is used, when too much air is supplied to the vent 57 side, a part of the air returns to the second discharge port 21, so that the air flow rate to each path is adjusted better. it can.
<Filter>
FIG. 7 is an exploded perspective view of the filter 11 as seen from the front upper right side, and shows only the prefilter 12 and the filter holder 11A.

  Referring to FIG. 1, the filter 11 can be maintained by removing the front decorative panel 5 from the main body case 2. As shown in FIG. 7, the filter 11 includes a vertically long and thin box-shaped filter holder 11A whose front surface is opened over the entire area. The main filter 13 and the deodorizing filter 14 described above (see FIG. 2). ) Is accommodated in the filter holder 11A. The pre-filter 12 is detachably attached to the filter holder 11A from the front side.

  Here, two engaging portions (referred to as first engaging portions 11B) are formed on the upper edge of the peripheral edge defining the front opening of the filter holder 11A with a space in the left-right direction. One engaging portion (referred to as the second engaging portion 11C) is also formed at a lower position on both end portions. The first engaging portion 11B and the second engaging portion 11C protrude to the front side, and a hole is formed at a substantially central position thereof. The prefilter 12 is formed with two protrusions (referred to as first protrusions 12 </ b> A) protruding upward at the upper end of the prefilter 12 at intervals in the left-right direction. One protrusion (referred to as a second protrusion 12B) that protrudes outward in the width direction is formed at one position. Further, in the pre-filter 12, a rib (referred to as a handle 12C) that protrudes to the front side is provided in the vicinity of each second protrusion 12B. As will be described later, the first protrusion 12A, the second protrusion 12B, and the handle 12C are separate parts from the mesh portion of the prefilter 12.

  After grasping the handle 12C and moving the prefilter 12, the first protrusion 12A is fitted into the corresponding hole of the first engaging portion 11B, and then the prefilter 12 is swung back around the first protrusion 12A. When the second protrusions 12B are fitted into the corresponding holes of the second engaging portions 11C, the prefilter 12 is attached to the filter holder 11A. On the other hand, when the prefilter 12 is attached to the filter holder 11A, when the handle 12C is grasped and pulled out to the front side, the second protrusion 12B is first removed from the hole of the second engaging portion 11C. Then, the pre-filter 12 is swung forward around the first protrusion 12A, and the first protrusion 12A is removed from the hole of the first engaging portion 11B. Thereby, the pre-filter 12 can be detached from the filter holder 11A. Here, the first protrusion 12A and the second protrusion 12B protrude in different directions (the protrusion direction of the first protrusion 12A is the vertical direction, and the protrusion direction of the second protrusion 12B is the width direction). Therefore, compared with the case where the protruding direction of the first protrusion 12A and the protruding direction of the second protrusion 12B are the same (for example, both in the width direction), each protrusion is smoothly fitted into the hole of the corresponding engaging portion. Can be removed or removed.

  Such attachment / detachment of the pre-filter 12 with respect to the filter holder 11A can be performed after the filter holder 11A is detached from the main body case 2, but can also be performed with the filter holder 11A attached to the main body case 2. In that case, since it is not necessary to touch the filter holder 11A and the mesh portion (stained portion) of the prefilter 12, the prefilter 12 is attached to and detached from the filter holder 11A without soiling the hand, and the prefilter 12 The main filter 13 and the deodorizing filter 14 can be maintained.

FIG. 8 is a front view of the pre-filter 12. FIGS. 9A and 9B are diagrams for explaining the molding of the prefilter 12, where FIG. 9A shows the prefilter 12 according to the present embodiment, and FIG. 9B shows the prefilter 12 according to the comparative example.
As shown in FIG. 8, the pre-filter 12 includes a resin frame (referred to as a filter frame 12D) and the above-described mesh portion (referred to as a net 12E). At least the front side of the filter frame 12D (the front side of the net 12E) is formed in a lattice shape. The first protrusion 12A, the second protrusion 12B, and the handle 12C described above are provided on a grid-like filter frame 12D. In addition, ribs (referred to as knobs 12F) are provided on the front face of the grid-like filter frame 12D at the four corners thereof so as to project frontward in an L shape when viewed from the front. The knob 12F is gripped when the prefilter 12 is moved, like the handle 12C.

When molding such a prefilter 12, as shown in FIG. 9 (b), the four corners of the net 12E are pierced into pins 12H fixed to the mold 12G, and the net 12E is positioned in the mold 12G. The mold 12G is closed, the resin is injected into the mold 12G, and the filter frame 12D is formed so that the filter frame 12D is welded to the net 12E. In the net 12E of the pre-filter 12 thus molded, the mesh 12I of the portion where the pin 12H is pierced (see the enlarged portion surrounded by a circle in FIG. 8) spreads as a trace of the pin 12H. Therefore, the appearance of the prefilter 12 in the vicinity of the mesh 12I is poor. Therefore, in the prefilter 12 of this embodiment, the spread mesh 12I is hidden in the filter frame 12D so as not to be exposed. That is, in the molding die 12G for the pre-filter 12, the pin 12H arranged at a position away from the filter frame 12D in FIG. 9B is replaced with the filter frame 12D (details) as shown in FIG. Are arranged so as to fit in the knob 12F). Therefore, the trace of the pin 12H is hidden in the knob 12F and cannot be seen from the front.
<Electrolytic water mist generating unit>
As shown in FIG. 2, an electrolyzed water mist generating unit 30 is attached to the air cleaner 1 so as to be covered with the wall surface of the main frame 4 at the upper left end of the main body case 2 (specifically, the main frame 4). ing. As will be described later, the electrolyzed water mist generating unit 30 diffuses the electrolyzed water mist using the purified air after passing through the filter 11. Therefore, the air cleaner 1 not only cleans the outside air taken in as described above with the filter 11, but also dissipates the electrolyzed water mist in the electrolyzed water mist generating unit 30, and external air is generated by the electrolyzed water mist. Can be sterilized and deodorized.

FIG. 10 is a longitudinal sectional view of the electrolyzed water mist generating unit 30 as viewed from the front. 11 is a cross-sectional view based on the line AA in FIG. 12A is a cross-sectional view based on the line BB in FIG. 10, and FIG. 12B is a cross-sectional view based on the line AA in FIG.
The electrolyzed water mist generating unit 30 includes an electrolyzed water mist generating part 31 disposed on the lower side and a tank 32 disposed on the upper side as viewed from the front side. On the right side of the electrolyzed water mist generating part 31, an electrical connection part (not shown) is provided. This electrical connection portion (not shown) is a jack (not shown) connected to an electrical board (not shown) provided in the main body case 2 when the electrolyzed water mist generating unit 30 is set in the air cleaner 1. )).

  10 and 11, the electrolyzed water mist generating unit 30 includes a tray 33, a main case 34, a cover 35, and the tank 32 described above. The tray 33 defines the lower part of the electrolyzed water mist generating unit 30. The main case 34 has a box shape with an upper surface opened (the opened portion is referred to as a case opening 27), and is fitted into the tray 33 from above. An internal space of the main case 34 is a water storage chamber 49. The cover 35 is detachably engaged with the main case 34 (specifically, they are fixed to each other with a clamp (not shown)), covers the upper part of the main case 34, and closes the case opening 27 from above. . The cover 35 is formed with a through hole (referred to as a water supply port 35 </ b> A) at a position biased to the right side (corresponding to a substantially central portion in the left-right direction of the water storage chamber 49). The tank 32 is detachably attached to the cover 35 from above so as to be inserted into the water supply port 35A. The tray 33, the main case 34, and the cover 35 constitute an electrolyzed water mist generating unit 31. In addition, the parts painted black in the figure are packings (the same applies to other figures).

  As shown in FIG. 10, the tank 32 is long in the left-right direction, and is detachable from the tank main body 28 having an opening (referred to as a tank opening 37) at the lower end, and the tank opening 37. And a cap 29 fitted inside. The tank body 28 is set so that the tank opening 37 faces downward. The cap 29 faces the main case 34 from above via the water supply port 35A.

  The water stored in the tank body 28 falls into the main case 34 when the opening / closing mechanism 38 provided in the cap 29 opens the tank opening 37 and is stored in the water storage chamber 49. Then, water is supplied from the tank 32 to the water storage chamber 49 so that the water level accumulated in the water storage chamber 49 is maintained at a predetermined water level 39 (about half of the depth of the water storage chamber 49) indicated by a one-dot chain line in the drawing. Done. The periphery of the cap 29 (including the opening / closing mechanism 38) will be described in detail later.

  In the water storage chamber 49, an electrolysis chamber 40 (first water storage chamber) is defined on the right side of the water supply port 35A. A pair of electrode plates 41 held by an electrode holding member 44 is provided in the electrolysis chamber 40. The pair of electrode plates 41 is formed, for example, by coating a titanium plate with a catalyst such as a ruthenium-based material. The pair of electrode plates 41 in the electrolysis chamber 40 is immersed in water, and when a voltage is applied to the pair of electrode plates 41 via lead wires (not shown), the water in the electrolysis chamber 40 is electrolyzed. It becomes electrolyzed water.

More specifically, the pair of electrode plates 41 are alternately arranged to have opposite polarities intermittently (for example, about 3 to 10 minutes every hour) via lead wires (not shown). A voltage (for example, 10 V) is applied so that a predetermined current (for example, 40 mA) flows, and thereby water in the electrolysis chamber 40 is electrolyzed. As water, tap water is usually used, and tap water contains chlorine. Therefore, the following electrochemical reaction occurs by electrolysis.
(Anode side)
4H ₂ O-4e ⁻ → 4H + + O ₂ ↑ + 2H ₂ O
2Cl ⁻ → Cl ₂ + 2e ⁻
H ₂ O + Cl ₂ ⇔HClO + H + + Cl ⁻
(Cathode side)
4H ₂ O + 4e ⁻ → 2H ₂ ↑ + 4OH ⁻
(Between electrode plates)
H ⁺ + OH ⁻ → H ₂ O
By the electrochemical reaction as described above, electrolyzed water containing hypochlorous acid (HClO) and active oxygen having a bactericidal action and a deodorizing action can be generated. By generating mist from the generated electrolyzed water as described later, electrolyzed water mist having a bactericidal action and a deodorizing action can be generated.

In the water storage chamber 49, a vibration imparting chamber 46 (second water storage chamber, mist generating chamber) is defined on the left side of the water supply port 35A. The vibration applying chamber 46 and the electrolysis chamber 40 communicate with each other, and water in the electrolysis chamber 40 can freely enter and leave the vibration applying chamber 46.
For example, a circular hole 48 having a circular shape in plan view is formed on the bottom surface of the vibration applying chamber 46, and the upper surface 51 of the ultrasonic transducer 50 disposed below faces the vibration applying chamber 46 through the circular hole 48. It is out. The electrolyzed water in the vibration applying chamber 46 rides on the upper surface 51 of the ultrasonic vibrator 50, and when the ultrasonic vibrator 50 operates, the water touching the upper surface 51 is ultrasonically vibrated, and the vibration applying chamber. The surface of the water accumulated in 46 rises in a mountain shape. At this time, electrolyzed water mist (hereinafter sometimes simply referred to as “mist”), which is minute water particles, is generated from the water surface.

The ultrasonic transducer 50 itself is disposed between the tray 33 and the main case 34 and has a mechanism in which power is supplied via the lead wire 53. The lead wire (not shown) connected to the pair of electrode plates 41 and the lead wire 53 are connected to the electric substrate (not shown) of the main body case 2 via the electric connecting portion (not shown). Power) is transmitted.
Here, as described above, in the water storage chamber 49, the electrolysis chamber 40 and the vibration applying chamber 46 are separated with the water supply port 35A interposed therebetween (see FIG. 10). The ultrasonic transducer 50 is separated from the pair of electrode plates 41 and the water level detection electrode plate 41A. This prevents the ultrasonic transducer 50 and the electrode plate 41 from being close to each other so that an electrical reaction occurs on the surface of the ultrasonic transducer 50 and the characteristics of the ultrasonic transducer 50 are deteriorated. Since the water surface on the sonic transducer 50 rises in a mountain shape and becomes unstable, the generation of electrolyzed water at the electrode plate 41 becomes unstable by separating the electrode plates 41 and 41A from the ultrasonic transducer 50. It is preventing. In particular, in this embodiment, the water level detection electrode plate 41A in the water storage chamber 49 (the ultrasonic vibrator 50 is stopped when the water level falls below the lower end of the electrode plate 41A) on the ultrasonic vibrator 50. The ultrasonic transducer 50 is not frequently stopped by detecting the water level fluctuation.

Therefore, the water in the tank 32 supplied to the water storage chamber 49 via the water supply port 35A can be reliably electrolyzed in the electrolysis chamber 40 and supplied to the vibration imparting chamber 46, so that the electrolyzed water mist can be reliably stabilized. Can be generated.
The upper portion of the vibration imparting chamber 46 is covered with a portion of the cover 35 on the left side of the water supply port 35A (referred to as a left portion 35B). The left part 35 </ b> B includes a first part 42 (air introduction path), a second part 43, and a third part 45. The first part 42, the second part 43, and the third part 45 are hollow.

  The first portion 42 is located at the left end of the left portion 35B, and has a hollow rectangular column shape that is long in the front-rear direction. As shown in FIG. 11, in the first portion 42, the lower portion of the rear end portion protrudes rearward (this is referred to as an introduction portion 42A), and an opening (one end opening 42B) is provided at the rear end of the introduction portion 42A. Is formed). An opening (referred to as the other end opening 42 </ b> C) is formed in the front portion of the right side wall of the first portion 42. Further, in the first portion 42, a vertical wall 42D is provided so as to protrude upward between the one end opening 42B and the other end opening 42C so as to face each other at a distance from the front side of the one end opening 42B. A predetermined gap 42E is formed between the upper end of the vertical wall 42D and the top wall of the first portion 42.

  As shown in FIG. 10, the inside of the second portion 43 is a substantially rectangular parallelepiped space communicating from the right side with respect to the other end opening 42 </ b> C, and its top surface (a part of the top surface of a mist drifting chamber 47 described later). Is defined by the top wall of the left side portion 35B. The inside of the second part 43 communicates with the vibration applying chamber 46 from above. In the second part 43, a substantially rectangular metal plate 43A is arranged. The metal plate 43A is supported by the top wall of the left side portion 35B in the second portion 43 and faces downward in the second portion 43, and the lower surface 43B thereof is in relation to the upper surface 51 of the ultrasonic transducer 50. It is opposed to the vertical direction at a predetermined interval.

  As shown in FIG. 12A, the inside of the third portion 45 is a substantially rectangular parallelepiped space communicating with the inside of the second portion 43 from the rear side, and its top surface (a mist drifting chamber 47 described later). Is parted by the top wall of the left side portion 35B. The inside of the third portion 45 communicates with the vibration applying chamber 46 from above. In the top wall of the left side portion 35B, the portion defining the top surface of the third portion 45 protrudes slightly downward compared to the other portions, and this portion has an elliptical opening that is long in the left-right direction. (Referred to as a mist outlet 45A as an outlet). The mist outlet 45A communicates with the inside of the third portion 45 from above. A mist guide path 54 is attached to the mist outlet 45A.

  The mist guide path 54 is a tube having a cross-sectional shape (elliptical shape) substantially equal to that of the mist outlet 45A, extends upward while slightly curving along the rear side surface of the tank 32, bends in the middle, and extends straight upward. ing. The bent portion in the mist guide path 54 is referred to as a bent portion 54A. The mist guide path 54 and the tank 32 are combined and integrated at the upper surface and the lower surface of the tank 32. The lower end of the mist guide path 54 is communicated with the mist outlet 45A by being inserted into the mist outlet 45A. As shown in FIG. 2, the upper end of the mist guiding path 54 penetrates a hole (referred to as a case hole 4B) formed in the upper side wall of the main frame 4 and protrudes upward from the upper side wall of the main frame 4. At the upper end, a mist diffusion port 55 is opened. Here, since the mist guiding path 54 is disposed along the side surface of the tank 32, the electrolyzed water mist generating unit 30 can be downsized.

  As shown in FIG. 10 and FIG. 12A, in the water storage chamber 49 (specifically, the vibration imparting chamber 46), the space above the water level accumulated up to the predetermined water level 39, the second portion 43 and the third portion 45. Thus, a mist drifting chamber 47 having a predetermined volume space is formed. That is, in the water storage chamber 49, a space is secured above the water surface of the predetermined water level 39 by the mist drift chamber 47. As described above, the mist generated by applying ultrasonic vibration to the electrolyzed water drifts in the mist drifting chamber 47.

The mist drifting in the mist drifting chamber 47 is diffused from the mist outlet 45 </ b> A to the outside of the air cleaner 1 through the mist guide path 54. The manner in which the mist is diffused will be described below.
As shown in FIG. 5, in the rear fan casing 17 </ b> B, air blown upward by the sirocco fan 9 is discharged to the outside through the second discharge port 22 (see the broken line arrow in the drawing) and the vent 57. It is also given to the electrolyzed water mist generating unit 30 through (see the one-dot chain line arrow in the figure). Air entering the electrolyzed water mist generating unit 30 side from the vent 57 enters the first portion 42 from the one end opening 42B, as indicated by a broken line arrow in FIG. Here, the direction of the air that has entered the first portion 42 is changed upward by colliding with the vertical wall 42D, and flows through the first portion 42 through the gap 42E. Since the other end opening 42C faces the second portion 43 (mist drifting chamber 47), the air flowing through the first portion 42 enters the mist drifting chamber 47 from the other end opening 42C. Thus, the first part 42 functions as an air introduction path for introducing the purified air supplied from the vent hole 57 into the mist drifting chamber 47.

  The air that has entered the mist drifting chamber 47 swirls in the mist drifting chamber 47 while pushing the mist drifting in the mist drifting chamber 47 as indicated by the broken line arrow in FIG. By this swirling, the mist having large particles is centrifuged, and the swirling air can select and sweep only the mist having fine particles. Here, since the mist with large particles is heavy, even if it reaches the mist radiating port 55 as will be described later, it is not smoothly diffused to the outside but accumulates around the mist radiating port 55 and causes dew condensation. Are preferably fine particles.

  Thereafter, the air strikes the inner wall surfaces of the main case 34 and the cover 35, so that the flowing direction is directed to the mist outlet 45A. Thus, the air flows from the mist outlet 45 </ b> A to the mist guide path 54, and is diffused to the outside from the mist discharge port 55 at the upper end of the mist guide path 54. Along with this, the mist in the mist drifting chamber 47 is pushed out to the mist outlet 45A by the air diffused to the outside, and is diffused to the outside through the mist guide channel 54.

  Thus, the vent 57 (see FIG. 2), the one end opening 42B (see FIG. 11), the first part 42 (see FIG. 11), the other end opening 42C (see FIG. 11), the mist drifting chamber 47, and the mist outlet 45A. The bypass channel that bypasses a part of the purified air is configured by the components such as the mist guide channel 54 and the mist diffusion port 55. And by the bypass flow path, the electrolyzed water mist drifting in the mist drifting chamber 47 can be satisfactorily carried by the purified air, and the electrolyzed water mist can be diffused to the outside from the mist diffuser port 55. At this time, the air flow for dissipating the mist is composed of the air that has passed through the filter 11 and is purified, and since the mist is carried and dissipated by the purified air, it is hygienic, Moreover, the electrolyzed water mist can be diffused indoors with clean air.

  Here, as described above, the guide ribs 24 (see FIG. 6) provided in the rear fan casing 17B flow in the rear fan casing 17B toward the second discharge port 22 along the broken line arrows in FIG. A part of the air is diverted to the vent 57 side (see the one-dot chain arrow in the figure). Therefore, a relatively large amount of air for diffusing the electrolyzed water mist generated by the electrolyzed water mist generating unit 30 to the outside can be secured by the diverted air. And by diverting the air flowing through the rear fan casing 17B by the guide rib 24, the flow velocity of the air diverted to the electrolyzed water mist generating unit 30 side can be increased. As a result, the electrolyzed water mist can be vigorously diffused to the outside by the diverted air. If electrolyzed water mist can be dissipated vigorously to the outside, condensation will occur due to stagnation of electrolyzed water mist around mist outlet 55 (see Fig. 2). 55) can be prevented.

  When the guide rib 24 has an I-shape as shown in FIG. 6A, the flow rate of the air diverted to the vent 57 (electrolyzed water mist generating unit 30) side is about 50 compared with the case where the guide rib 24 is not provided. % Can be increased. Further, if the guide rib 24 is L-shaped as shown in FIG. 6B, as shown in FIG. 5B, the air flowing toward the vent 57 on the upstream side of the guide rib 24 as viewed in the air flow direction. Can be returned to the second discharge port 21 side via the notch portion 24A (see FIG. 6B) of the guide rib 24 (see the two-dot chain line arrow in FIG. 5B). Therefore, in this air cleaner 1, the air flow from the second discharge port 22 is reduced by diverting more air than necessary in the air flowing in the rear fan casing 17 </ b> B to the electrolyzed water mist generating unit 30 side. This can be prevented. Thereby, the outflow amount of the purified air at the second discharge port 22 can be stably secured. That is, by providing such an L-shaped guide rib 24, the original function (stable supply of purified air) of the air cleaner 1 can be achieved while the electrolyzed water mist can be dissipated vigorously to the outside. Can be secured.

  As shown in FIG. 10, the mist drifting chamber 47 is secured above the surface of the water stored in the water storage chamber 49 up to a predetermined water level 39 (preferably the highest water level 39A that can be assumed). 12A, the top wall of the cover 35 in the third portion 45 where the mist outlet 45A is formed is the top surface of the mist drifting chamber 47. That is, the mist outlet 45 </ b> A through which the mist diffused to the outside passes is open to the top surface of the mist drifting chamber 47. Therefore, even if the water level stored in the water storage chamber 49 rises, it is possible to prevent the mist outlet 45A from being blocked by water. Can be released stably. That is, if the mist outlet 45A is not blocked by water, the mist is sequentially released from the mist outlet 45A to the outside, so that even if the water level rises to the highest water level 39A, it is lowered to the predetermined water level 39 thereafter. be able to.

Thus, since the mist drifting chamber 47 has a space of a predetermined volume, the mist drifting chamber 47 is reliably secured above the surface of the water accumulated in the water storage chamber 49 up to the predetermined water level 39 (including the highest water level 39A). Therefore, even if the water level of the water stored in the water storage chamber 49 rises, it is possible to reliably prevent the mist outlet 45A from being blocked by water.
In addition, when the ultrasonic vibrator 50 is continuously operated, the water in the water storage chamber 49 is heated by the vibration, and as the temperature increases, chlorine in the water easily evaporates, and when the water temperature reaches about 40 ° C. or higher, Most of the chlorine will evaporate. In this case, electrolyzed water containing hypochlorous acid (HClO) having the sterilizing action and deodorizing action described above cannot be generated. Therefore, it is necessary to intermittently operate the ultrasonic vibrator 50. In this case, since the mist drifting chamber 47 has a predetermined volume space, a relatively large amount of mist can be generated. Stable emission is possible.

  Further, since the mist drift chamber 47 has a space of a predetermined volume, the top surface of the mist drift chamber 47 (the top wall of the cover 35) and the water surface can be sufficiently separated from each other. This makes it difficult for the water in the water storage chamber 49 to jump up to the top surface of the mist drifting chamber 47, and it is possible to prevent the top surface of the mist drifting chamber 47 from being damaged by the ultrasonic energy possessed by the water.

  A metal plate 43A is provided on the top surface of the mist drifting chamber 47 so as to face the ultrasonic transducer 50 in the vertical direction. Therefore, even if the water in the water storage chamber 49 jumps up to the top surface of the mist drifting chamber 47 due to the vibration of the ultrasonic vibrator 50, the water is received by the metal plate 43A. Specifically, the metal plate 43A absorbs the ultrasonic energy of the splashed water and releases it as heat. Therefore, it is possible to prevent the splashed water from directly hitting the top surface of the mist drifting chamber 47 and damaging the top surface. Also, the splashed water hits the metal plate 43A, so that fine particles (air sterilization / deodorization of air) can be prevented. Highly effective mist can be generated.

  Further, in order to dissipate the electrolyzed water mist generated by the electrolyzed water mist generating unit 30 to the outside vigorously, a part of the air flowing in the rear fan casing 17B is provided on the vent 57 side by providing the guide rib 24 as described above. However, the configuration in the electrolyzed water mist generating unit 30 also contributes to the smooth diffusion of the electrolyzed water mist, which will be described below. Although these configurations may exist alone, they are combined with each other including the above-described guide ribs 24 to realize smoother dissipation of the electrolyzed water mist.

  Since the mist guide path 54 described above extends continuously upward from a mist outlet 45A provided on the top surface of the mist drifting chamber 47, the mist guide path 54 is prevented from staying in the middle of the mist guide path 54. Can be dissipated vigorously to the outside. Here, in the mist guide path 54, a rib (referred to as a throttle rib 54B) is provided inward of the mist diffusion port 55, specifically, slightly above the bent portion 54A of the guide path 54. As shown by the hatched portion in FIG. 12B, the throttle rib 54B has substantially the same cross-sectional shape as the mist guide path 54, and a hole (a throttle hole 54C) is formed at the center thereof. Therefore, referring to FIG. 12A, the flow rate of air flowing upward through the mist guide path 54 toward the mist radiating port 55 passes through the throttle hole 54C of the throttle rib 54B, and the flow rate of the air is reduced. Will increase. Thereby, the mist conveyed by this air can be vigorously dissipated from the mist dispersal port 55 to the outside.

Moreover, foreign objects such as coins can be prevented from entering the mist guide path 54 from the mist diffusion port 55 by the throttle rib 54B.
Further, the mist guiding path 54 is bent at a bent portion 54A, and the bent portion 54A can suppress release of mist having a large particle size from the mist diffusion port 55. The bent portion 54A tends to accumulate mist whose release is suppressed as water droplets. However, as described above, the throttle rib 54B is provided slightly off the bent portion 54A of the guide path 54. The water droplets accumulate over the throttle rib 54B and the bent portion 54A due to surface tension and smoothly flow down to the lower end (mist outlet 45A) of the guide path 54 and return to the water storage chamber 49 without blocking the throttle hole 54C.

FIG. 13 is a diagram showing another embodiment of the electrolyzed water mist generating unit, and is a diagram showing a modification of the configuration shown in FIG. 11.
As shown in FIG. 13, the cross-sectional area X at the one end opening 42 </ b> B of the first portion 42 in the cover 35 is the first portion 42 (specifically, the portion downstream from the one end opening 42 </ b> B in the air flow direction indicated by the solid line arrow in the figure). It is preferable that the cross-sectional area Y is larger. Therefore, in this embodiment, in the first portion 42, the bottom wall of the introduction portion 42A is inclined downward toward the rear side. Thereby, in the first portion 42, a relatively large amount of air is taken in from the vent 57 communicating with the rear fan casing 17B (see FIG. 5) in the one end opening 42B, and this air is relatively discharged in the other end opening 42C. The mist drifting chamber 47 can be introduced at a high flow rate. Therefore, a large amount of mist in the mist drifting chamber 47 can be carried on the air and dissipated vigorously. In this case, there is a slight gap between the one end opening 42B and the vent hole 57, but there is substantially no air leakage from this gap.

FIG. 14 is a diagram showing still another embodiment of the electrolyzed water mist generating unit, and is a diagram showing a modification of the configuration shown in FIG. 15 is a view showing a cross section of a portion different from FIG. 14 in the embodiment shown in FIG.
As shown in FIG. 14, the vent 57 may be wider than the one end opening 42 </ b> B of the first portion 42. In that case, a part of the air that is going to flow from the vent 57 to the one end opening 42B flows between the wall of the main frame 4 and the electrolyzed water mist generating unit 30 without reaching the one end opening 42B ( (See broken arrow in the figure). The air flowing between the wall of the main frame 4 and the electrolyzed water mist generating unit 30 is the wall of the main frame 4 and the tank 32 (including the mist guide path 54) as shown by the broken line arrows in FIG. A gap (referred to as an auxiliary air flow path 58) is raised along the outer periphery of the mist guide path 54. And the air which flows through the auxiliary air flow path 58 flows out upward from the case hole 4B on the upper side wall of the main frame 4 (see the broken arrow in the drawing). Here, since the upper end of the mist guiding path 54 is inserted into the case hole 4B, the air flowing out from the case hole 4B is discharged from the upper end of the mist guiding path 54, that is, from the periphery of the mist discharging port 55. It flows out along (see the solid line arrow in the figure). Therefore, the mist flowing through the mist guide channel 54 is discharged upward by the air flowing in the diffusing direction from the periphery of the mist radiating port 55 via the auxiliary air channel 58, and the environment (temperature) around the mist diffusing port 55 is released. And humidity etc.). Thereby, for example, referring to FIG. 2, the mist (see the solid line arrow) reaching the mist diffusion port 55 is attracted or pushed out to the air (see the broken line arrow) flowing out from the second discharge port 22. Thus, wetting of the upper side wall of the main frame 4 around the mist diffusion port 55 can be prevented. Therefore, even the mist having a large particle size described above can be radiated vigorously from the mist radiating port 55 to the outside without causing condensation around the mist radiating port 55.
<Cap>
16A and 16B are views showing the cap 29 of the tank 32, wherein FIG. 16A is a longitudinal sectional view of the cap 29 at the center of the circle, and FIG. 16B is a bottom view of the cap 29. FIG. FIG. 17 is a view in which a partition 29E is provided in FIG.

  As shown in FIG. 16A, the cap 29 has a hollow cylindrical shape having an axis 29A extending in the vertical direction. Near the center of the cap 29 in the axial direction, three ribs 29B extending radially toward the outer peripheral wall of the cap 29 are provided along a direction orthogonal to the axis 29A (see FIG. 16B). A cylindrical portion 29 </ b> C extending along the axial direction is provided at a connecting portion (see FIG. 16B) of the three ribs 29 </ b> B.

  Between the outer peripheral surface of the cylinder 29 </ b> C and the inner peripheral surface of the outer peripheral wall of the cap 29, a gap (a hatched portion in the drawing, referred to as a drop passage 36) is formed. The drop passage 36 communicates with the outside on the lower side, and can communicate with the inside of the tank body 28 (see FIG. 10) on the upper side. The hollow portion 29D of the cylinder 29C communicates with the inside of the tank body 28, and the opening / closing mechanism 38 described above is provided in the hollow portion 29D.

  The opening / closing mechanism 38 includes a shaft portion 38A that is loosely fitted in the hollow portion 29D, and an umbrella portion 38B that is attached to the upper end portion of the shaft portion 38A and disposed in the tank body 28 (see FIG. 10). The opening / closing mechanism 38 is slidable in the axial direction with respect to the cap 29 when the shaft portion 38A is loosely fitted in the hollow portion 29D. Here, the opening / closing mechanism 38 is always urged downward by an urging means such as the illustrated spring 38C (which may be the weight of the opening / closing mechanism 38). In this state, the umbrella portion 38B moves through the drop passage 36. It is closed from the upper side (inside the tank body 28). In other words, the drop passage 36 of the cap 29 is always blocked from the inside of the tank main body 28 (see FIG. 10) by the opening / closing mechanism 38, and accordingly, the tank opening 37 (see FIG. 10) of the tank main body 28 is formed. Closed.

  Here, as shown in FIG. 10, in the water storage chamber 49 of the electrolyzed water mist generating unit 30, a pin protruding upward from the bottom wall of the main case 34 toward the water supply port 35A is provided below the water supply port 35A. (Referred to as a protruding pin 34A). Therefore, as described above, when the tank 32 is set from the upper side with respect to the cover 35 (water storage chamber 49) and the cap 29 is fitted into the water supply port 35A, the opening / closing mechanism 38 is pushed up by the protruding pin 34A. At this time, the opening / closing mechanism 38 rises against the urging force of the spring 38C (see FIG. 16A), so that the umbrella portion 38B opens the drop passage 36 of the cap 29 upward, and the tank opening is accordingly generated. 37 is opened. As a result, the inside of the tank body 28, the drop passage 36, and the water storage chamber 49 communicate with each other. In this state, the water inside the tank body 28 falls in the drop passage 36 and is stored in the water storage chamber 49. When the water level in the water storage chamber 49 rises to the lower end of the cap 29 (which is also the lower end of the drop passage 36 and corresponds to the predetermined water level 39 described above), the water supply from the tank 32 to the water storage chamber 49 is stopped. At this time, the fall passage 36 is filled with water. On the other hand, when removing the tank 32 from the water storage chamber 49, the push-up of the opening / closing mechanism 38 by the projecting pin 34A is released, so that the umbrella portion 38B closes the drop passage 36 of the cap 29 from above, and the tank Since 37 is closed, water does not leak from the tank opening 37.

  Here, when the tank 32 is removed from the water storage chamber 49, the water accumulated in the drop passage 36 falls into the water storage chamber 49, so that compared to when the tank 32 is set in the water storage chamber 49, The water level rises. Therefore, if the setting of the tank 32 to the water storage chamber 49 and the removal from the water storage chamber 49 are repeated alternately many times, the water level in the water storage chamber 49 may rise more than necessary. Specifically, the rise in the water level reaches the highest water level 39A (see FIG. 10). When the water level reaches the highest water level (in FIG. 11, it is equal to the height up to the vertical wall 42D), the water climbs over the vertical wall 42D and flows out into the main body case 2 from the one end opening 42B of the introduction portion 42A. The case 2 gets wet. In addition, when the height of the cover 35 is low, the mist outlet 45A of the mist drifting chamber 47 may be blocked with water, and the mist may not be stably dissipated to the outside.

However, in this embodiment, as shown in FIG. 17, an annular partition 29 </ b> E surrounding the cylinder 29 </ b> C is provided in the lower portion between the outer peripheral surface of the cylinder 29 </ b> C and the inner peripheral surface of the outer peripheral wall of the cap 29. ing. Since the partition 29E restricts the volume of the drop passage 36 (see the hatched portion in the drawing) from increasing downward, compared to the case without the partition 29E (see the shaded portion showing the drop passage 36 in FIG. 16), The amount of water accumulated in the drop passage 36 can be reduced. Further, the water collected in such a narrow drop passage 36 becomes difficult to fall due to surface tension. Therefore, even if the tank 32 is set and removed repeatedly, the water level rise in the water storage chamber 49 can be minimized, and the water level is prevented from rising to the highest water level 39A as much as possible.
<Human sensor>
As shown in FIG. 2, the human sensor 60 is provided on the inner panel 4 </ b> C that forms the front side wall of the upper portion of the main frame 4 above the front space 26. The human sensor 60 detects the presence of a person in front of the air cleaner 1 by using, for example, infrared rays (so-called IR sensor). When the human sensor 60 detects the presence of a person, a control (not shown) is performed. The operation status of the air cleaner 1 is changed by the unit. In this case, for example, the amount of air to be cleaned and the generation amount of electrolyzed water mist increase.

On the back surface of the inner panel 4C, there are two bosses (referred to as first bosses 64), one boss (referred to as second bosses 67), and one hook (referred to as panel hooks 68). Is provided. As shown in FIG. 18B, the two first bosses 64 protrude rearward so as to sandwich the panel hole 66 from the left and right. As shown in FIG. 18C, the second boss 67 protrudes rearward above the panel hole 66. The panel hook 68 projects rearward below the panel hole 66. As shown in FIG. 1, the front decorative panel 5 has a through hole (referred to as a small hole 72) at a position facing the panel hole 66 of the inner panel 4C.

  As shown in FIG. 18A, the electric circuit board 62 has a substantially rectangular shape in a front view and a thin plate shape in the front-rear direction. Both ends of the electric circuit board 62 in the width direction are fixed to the rear ends of the two first bosses 64 by screws 65 (see FIG. 18B). In other words, the electric circuit board 62 is fixed to the first boss 64 so as to be spaced apart from the back surface of the inner panel 4C.

  As shown in FIGS. 18B and 19B, the human sensor 60 is mounted on the front surface 62 </ b> A of the electric circuit board 62. The human sensor 60 includes a columnar base 60A that protrudes in a cylindrical shape from the front surface 62A of the electric circuit board 62, and a hemispherical tip 60B formed at the tip (front end) of the columnar base 60A. Yes. As shown in FIG. 18C, a sensor main body 60C that is electrically connected to the electric circuit board 62 is disposed inside the columnar base 60A and the hemispherical tip 60B. The outer surfaces of the columnar base 60A and the hemispherical tip 60B serve as a cover for protecting the sensor main body 60C, and are therefore formed of metal.

  The two LEDs 63 are both cylindrical LEDs that emit blue light. As shown in FIG. 18B and FIG. 19B, the two LEDs 63 are mounted on the front surface 62A of the electric circuit board 62 in the same manner as the human sensor 60. Specifically, as shown in FIGS. 18A and 19A, the two LEDs 63 are arranged so as to be separated from each other by 180 ° in the circumferential direction centering on the human sensor 60.

  As shown in FIG. 18C, the ring lens 61 integrally includes a thick ring lens 61A, a thin ring lens 61B, and a lens support portion 61C. The thick ring lens 61 </ b> A and the thin ring lens 61 </ b> B are both annular formed of a transparent resin or the like, and the axis thereof extends in the front-rear direction. The thick ring lens 61A is thicker than the thin ring lens 61B. The thin ring lens 61B protrudes forward from the front end of the thick ring lens 61A. Further, the inner peripheral surface of the thick ring lens 61A and the inner peripheral surface of the thin ring lens 61B have the same size and are continuous with each other. That is, in the state where the thin ring lens 61B is connected to the thick ring lens 61A, the thick ring lens 61A and the thin ring lens 61B have a common inner peripheral surface 61D.

  As shown in FIG. 19B, the rear end face (referred to as the bottom face 61E) of the thick ring lens 61A is flat in the vertical and horizontal directions (specifically, substantially parallel to the front surface 62A of the electric circuit board 62). It extends to. The above-described inner peripheral surface 61D rises at a right angle to the bottom surface 61E. A corner 61F that is a boundary between the inner peripheral surface 61D and the bottom surface 61E is chamfered. Here, as shown in FIG. 19C, the bottom surface 61E and the C-chamfered surface at the corner 61F are subjected to white background paint (the hatched display portion shown in the drawing, referred to as the paint portion 61G). Further, as shown in FIG. 19A, a pair of notches 61H cut from the outer peripheral surface is formed at positions 180 ° apart in the circumferential direction on the outer peripheral portion of the thick ring lens 61A. Yes.

As shown in FIG. 18A, the lens support 61C has a rod shape that is long in the vertical direction. Specifically, as shown in FIG. 18C, the lens support portion 61C is bent in a crank shape toward the front side as it goes downward, and its lower end portion is connected to the upper end portion of the thick ring lens 61A. ing.
In the ring-shaped lens 61, the upper end portion of the lens support portion 61 </ b> C is fixed to the rear end portion of the second boss 67 with a screw 69. Since the lens support portion 61C has a crank shape as described above, the lens support portion 61C extends downward along the second boss 67 and the inner panel 4C. The thick ring lens 61A and the thin ring lens 61B supported by the lens support portion 61C are arranged so that the thin ring lens 61B is inserted into the panel hole 66. Here, the panel hook 68 is engaged with the lower end portion of the thick ring lens 61A, and the thick ring lens 61A and the thin ring lens 61B are positioned. As described above, the ring lens 61 is not mounted on the electric circuit board 62.

  In this state, the front end portion of the thin ring lens 61B protrudes forward from the inner panel 4C. In addition, the bottom surface 61E of the thick ring lens 61A is opposed to the front surface 62A of the electric circuit board 62 with a predetermined gap 70 in the front-rear direction. The human sensor 60 is inserted inside the thick ring lens 61A and the thin ring lens 61B. The human sensor 60 is surrounded from the outer side in the circumferential direction by a ring-shaped lens 61 (the inner peripheral surface 61D of the thick ring lens 61A and the thin ring lens 61B). Specifically, the thick ring lens 61A surrounds the cylindrical base 60A of the human sensor 60, and the thin ring lens 61B surrounds the hemispherical tip 60B of the human sensor 60. Although not shown, the tip (front end) and hemispherical tip 60B of the thin ring lens 61B face outward (front) from the small hole 72 (see FIG. 1) of the front decorative panel 5. Here, the tip (front end) of the thin ring lens 61B is slightly in front of the tip of the hemispherical tip 60B, but is in the rear of the front side of the front decorative panel 5. And as shown to Fig.18 (a), in two LED63, each front-end | tip (it is called head 63A) is stored in the corresponding notch part 61H in the thick ring lens 61A.

  In this state, when the human sensor 60 detects the presence of a person as described above, power is supplied from the electric circuit board 62, whereby the two LEDs 63 emit blue light. In this case, the light emitted from each LED 63 first enters the thick ring lens 61A through the notch 61H from the head 63A shown in FIG. Then, this light advances in the circumferential direction in the thick ring lens 61A as shown by the solid line arrow in FIG. 19A, and as shown by the solid line arrow in FIG. 19B, the thick ring lens 61A. Proceed to the inner peripheral surface 61D side. The light traveling toward the inner peripheral surface 61D side is refracted toward the thin ring lens 61B side (front side) on the C-chamfered surface at the corner 61F described above. Therefore, the ring-shaped lens 61 can be made to shine uniformly blue in a circle shape toward the front side by the light emitted from the LED 63. Thereby, the human sensor 60 can be beautifully decorated from the surroundings. This state is exposed outward (forward) by a small hole 72 (see FIG. 1) formed in the front decorative panel 5. As a result, it is possible to positively appeal to the user that the human sensor 60 that is one of the functionalities of the air cleaner 1 is provided and that the human sensor 60 is functioning. Further, by applying white paint on the C-chamfered surface of the bottom surface 61E and the corner 61F of the thick ring lens 61A (providing the paint part 61G), only the existing LED 63 can be used without increasing the light emission amount of the LED 63. The ring-shaped lens 61 can be clearly illuminated.

  Here, referring to FIG. 18B, the LED 63 used in this embodiment has a relatively large diameter (for example, a diameter of 5 mm). Therefore, compared with the case where the LED 71 having a smaller diameter than the LED 63 (for example, 3 mm in diameter) is used (see FIG. 18D), the thick ring lens 61A is used to accommodate the head 63A of the large-diameter LED 63 in the notch 61H. Also, the thin ring lens 61B is shifted to the front side (the direction away from the front surface 62A of the electric circuit board 62). Therefore, the gap 70 in the front-rear direction between the bottom surface 61E of the thick ring lens 61A and the front surface 62A of the electric circuit board 62 is relatively large. In this embodiment, the gap 70 is, for example, 1.5 mm (when the small-diameter LED 71 in FIG. 18D is used, the gap 70 is as small as 0.5 mm), and when the human sensor 60 gets wet. The size is such that the invading water cannot stay with the surface tension. Therefore, referring to FIG. 18C, moisture that has entered between the ring-shaped lens 61 and the human sensor 60 is moved between the front surface 62A of the electric circuit board 62 and the bottom surface 61E of the thick ring lens 61A. It can be washed away without stopping. Further, since the corner 61F between the bottom surface 61E and the inner peripheral surface 61D of the thick ring lens 61A is chamfered, moisture does not accumulate at the corner 61F. As a result, even if moisture enters between the ring lens 61 and the human sensor 60, the gap 70 between the front surface 62A of the electric circuit board 62 and the bottom surface 61E of the thick ring lens 61A via the C chamfered portion. It is possible to prevent the human sensor 60 from being corroded by the moisture.

Further, since the gap 70 described above is provided between the electric circuit board 62 and the bottom surface 61E of the thick ring lens 61A, even if the air cleaner 1 falls and the ring lens 61 collides with the floor surface, It is possible to prevent the thick ring lens 61A from hitting the electric circuit board 62 and damaging the electric circuit board 62. Here, as shown in FIG. 1, the front surface of the main frame 4 is covered with the front decorative panel 5 so that the ring-shaped lens 61 does not protrude forward, as described above. Therefore, even if the air cleaner 1 falls forward while the main frame 4 is covered with the front decorative panel 5, the ring-shaped lens 61 can be prevented from colliding with the floor surface.
<Front decorative panel>
FIG. 20 is a perspective view of the front decorative panel 5 as viewed from the lower right side of the back surface, where (a) shows the entire front decorative panel 5 and (b) is an enlarged view of the upper left end of the front decorative panel 5. As shown.

  As shown in FIG. 20, the front decorative panel 5 includes a main surface plate 75 and an auxiliary plate 76. The main surface plate 75 has a substantially flat plate shape that is long in the vertical direction and has a substantially rectangular shape in front view, and is made of a transparent resin or the like. In the main surface plate 75, almost the entire area of the back surface (back surface) is painted, for example, in white, so that the front surface of the main surface plate 75 is glossy. Moreover, in the front decoration panel 5, the upper side part and the lower side part are curving to the back side. Specifically, the upper side portion of the front decorative panel 5 is curved over the entire region in the width direction (this portion is referred to as an upper curved portion 77). And in the lower side part of the front decoration panel 5, only the width direction both ends protrude below, and are curving to the back side compared with the other part (The lower curved part which uses these parts as a lower latching | locking part) 78.) The lower curved portion 78 will be described in detail later.

The rear end portion 77 </ b> A of the upper bending portion 77 is flat along the front / rear / left / right direction over the entire region of the upper bending portion 77 in the width direction. Both ends in the width direction of the rear end portion 77A are bent downward (this portion is referred to as a bent portion 77B). The rear lower edge of the bent portion 77B extends obliquely upward and rearward.
A plurality of through holes 80 are formed in the rear end 77A. These through holes 80 are classified into a first through hole 80A, a second through hole 80B, and a third through hole 80C according to the shape. The first through holes 80A have a substantially elliptical shape that is long in the front-rear direction, and, for example, six are formed at intervals in the width direction in the vicinity of the rear end edge of the rear end portion 77A. The second through holes 80B have a substantially rectangular shape that is slightly longer in the width direction. For example, three second through holes 80B are formed on the front side of the first through hole 80A at substantially equal intervals in the width direction. The third through-hole 80C has a substantially rectangular shape that is smaller in the front-rear direction than the second through-hole 80B. For example, four third through-holes 80C are formed on the front side of the second through-hole 80B at substantially equal intervals in the width direction. .

  The auxiliary plate 76 has a rectangular plate shape that is long in the width direction substantially equal to the rear end portion 77 </ b> A of the upper curved portion 77. The auxiliary plate 76 is made of an opaque resin or the like. Both ends of the auxiliary plate 76 in the width direction are bent downward (this portion is referred to as a bent portion 76A). The front end portion of the bent portion 76A is bent inward in the width direction and is further bent slightly upward. In other words, the front end portion of the bent portion 76A has a hook shape (this portion is referred to as a first hook portion 76B). Further, the rear end of the auxiliary plate 76 is bent downward over the entire width direction, and a part thereof is further bent forward (this portion is referred to as a second hook portion 76C). For example, six second hook portions 76C are provided at intervals in the width direction.

  A plurality of projections 81 projecting downward are provided in a region sandwiched between the bent portions 76 </ b> A at both ends in the width direction on the back surface (lower surface) of the auxiliary plate 76. These protrusions 81 are classified into a first protrusion 81A, a second protrusion 81B (locking protrusion), and a third protrusion 81C according to the shape. For example, six first protrusions 81 </ b> A have a columnar shape and are spaced apart from each other in the width direction at approximately the center in the front-rear direction of the auxiliary plate 76. For example, three second protrusions 81B are formed on the front side of the first protrusion 81A at substantially equal intervals in the width direction. Each of the second protrusions 81B is integrally formed by a pair of plate-like ribs whose front lower end is curved and a rectangular rib laid between the rear ends of these ribs ( (Refer FIG.20 (b)). The third protrusion 81C has a hook shape in which the lower end portion slightly protrudes obliquely rearward and upward (see FIG. 20B), and on the front side of the second protrusion 81B, with a substantially equal interval in the width direction, for example, Four are formed.

  FIG. 21 is a diagram for explaining a state in which the first hook portion 76B is engaged with the bent portion 77B. FIG. 22 is a rear view of the upper portion of the front decorative panel 5 immediately after the engagement of the first hook portion 76B with the bent portion 77B is completed. FIG. 23 is a bottom view of the upper curved portion 77 of the main surface plate 75 in a state where all the protrusions 81 are fitted in the corresponding through holes 80. 24A is a cross-sectional view based on the line AA in FIG. 23, FIG. 24B is a cross-sectional view based on the line BB in FIG. 23, and FIG. It is sectional drawing based on CC line, (d) is sectional drawing based on the DD line of FIG.

  The auxiliary plate 76 is attached to the rear end portion 77A of the upper curved portion 77 of the main surface plate 75 from the rear side (see the thick arrow in FIG. 20B). At this time, first, as shown in FIG. 21, the first hook portion 76B of the auxiliary plate 76 is engaged with the corresponding bent portion 77B at the rear end portion 77A. Here, as described above, since the rear lower end edge of the bent portion 77B is inclined obliquely rearward and upward, the first hook portion 76B can be smoothly engaged with the bent portion 77B. .

  And when each 1st hook part 76B reaches | attains the front end of the bending part 77B, the engagement with respect to the bending part 77B of the 1st hook part 76B is completed. Thereby, the shift | offset | difference to the width direction of the auxiliary | assistant board 76 is prevented. Immediately after the engagement of the first hook portion 76B with the bent portion 77B is completed, as shown in FIG. 22, the central portion of the auxiliary plate 76 is deformed, and the protrusion 81 is lifted from the upper side surface of the rear end portion 77A. Or on the upper surface of the rear end 77A. Therefore, each projection 81 is pushed downward and fitted into the corresponding through hole 80.

Specifically, as shown in FIG. 23, the first projection 81A is fitted into the first through hole 80A, the second projection 81B is fitted into the second through hole 80B, and the third projection 81C is fitted into the third through hole 80C. Include.
In this state, as shown in FIG. 24A, the first hook portion 76B reaches the front end of the bent portion 77B, and the second hook portion 76C moves the rear end of the rear end portion 77A in the vertical direction. Is sandwiched between. Further, as shown in FIG. 24B, the third protrusion 81C is engaged from the lower side with a portion forming the rear periphery of the third through hole 80C in the rear end portion 77A. Further, as shown in FIG. 24C, the second protrusion 81B is loosely fitted in the second through hole 80B and protrudes downward from the rear end 77A. Then, as shown in FIG. 24D, the first protrusion 81A is loosely fitted in the first through hole 80A. Thereafter, since the first protrusion 81A is heated and crushed, the auxiliary plate 76 is thermally welded to the main surface plate 75.

  As described above, in the front decorative panel 5, the main surface plate 75 is formed of a transparent material, whereas the protrusion 81 is formed on the back surface of the auxiliary plate 76 formed of an opaque material separate from the main surface plate 75. Since it is formed, the protrusion 81 does not stand out, and the appearance can be improved. Further, since the auxiliary plate 76 can be reliably attached to the main surface plate 75 by heat welding without using screws or the like, the manufacturing cost can be reduced. In addition, since the front decorative panel 5 is attached to and detached from the main frame 4 at a relatively high frequency, a predetermined strength is required for a joint portion between the auxiliary plate 76 and the main surface plate 75, but thermal welding is used. As a result, it is possible to strengthen the joint portion as compared with the case where a screw or the like is used.

FIG. 25 is a perspective view of the front decorative panel 5 as seen from the upper right side of the back surface. 26A and 26B are views showing the periphery of the lower curved portion 78, in which FIG. 26A is a front view, FIG. 26B is a rear view, and FIG. It is sectional drawing based on A line.

Although the claw 78B is formed of an opaque material, the claw 78B is disposed below the curved portion in the lower curved portion 78, so that the lower curved portion 78 is viewed from the front as shown in FIG. However, the nail 78B is not transparent. And as shown in FIG.26 (c), the nail | claw 78B engages with the reinforcement material 83 from the back side, and the reinforcement material 83 is drawn near to the lower curved part 78. FIG. In this way, the reinforcing member 83 is fixed to the lower curved portion 78 by the screw 84 and the claw 78B described above. Moreover, as shown in FIG. 26B, both ends in the width direction of the lower curved portion 78 are bent upward, and the reinforcing member 83 is sandwiched from both sides in the width direction by these bent portions. A rib (locking rib 85) that is recessed outward in the width direction is provided on the upper portion of the back surface of the reinforcing member 83.

Such a reinforcing member 83 can ensure the rigidity of the lower curved portion 78. Further, as will be described later, the front decorative panel 5 can be positioned in the air cleaner 1 by the locking rib 85.
The reinforcing member 83 is formed of an opaque material, but is attached to the back side of the lower curved portion 78 that curves to the back side at the lower side of the main surface plate 75. Further, the above-described locking rib 85 is provided not on the lower curved portion 78 but on the reinforcing member 83. As a result, the reinforcing member 83 and the locking rib 85 do not stand out, and the appearance can be improved.

FIG. 27 is a cross-sectional view of the front decorative panel 5 and the periphery of the upper end portion of the main frame 4 for explaining the attachment of the front decorative panel 5 to the main frame 4. FIG. 28 is a cross-sectional view of the front decorative panel 5 and the main frame 4 around the locking rib 85 for explaining the attachment of the front decorative panel 5 to the main frame 4.
Hereinafter, attachment of the front decorative panel 5 to the main frame 4 will be described. First, as shown in FIG. 1, three concave portions 87 are provided in the upper side wall of the main frame 4 at intervals in the width direction. Further, on the front side surface of the main frame 4, hooks 86 are provided at the lower ends of both end portions in the width direction.
