Description

Electric vacuum cleaner {ELECTRICAL CLEANER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric cleaner for removing odors in the cleaner body using a photocatalyst.

BACKGROUND ART In conventional vacuum cleaners, photocatalytic treatment is performed on an inner wall surface or a dust bag of a dust collecting chamber, and a portion of the photocatalytic treatment is irradiated with ultraviolet rays from an ultraviolet lamp to kill microorganisms such as bacteria (for example, See Patent Document 1).

Patent Document 1: Japanese Patent Application Laid-Open No. 2001-370

However, in such an electric cleaner, it is expected to kill microorganisms such as bacteria, but a satisfactory odor removing effect could not be expected.

Therefore, an object of the present invention is to provide an electric vacuum cleaner which can expect a sufficient odor removing effect.

In order to achieve the above object, the present invention provides a dust collecting unit for collecting dust, an electric blower for applying suction negative pressure to the dust collecting unit, a communication air passage provided with the dust collecting unit and the electric blower, and the air blower installed in the communication air passage. An ultraviolet light cleaner comprising a photocatalyst-treated odor removing member, a light source for emitting ultraviolet light, and an ultraviolet light emitter receiving ultraviolet light from the light source to emit light to irradiate the ultraviolet light to the odor removing member. The light emitter is formed in a shape capable of irradiating ultraviolet rays by surrounding the odor removing member.

According to this structure, when light is emitted from the ultraviolet light emitter, the ultraviolet light emitted from the ultraviolet light emitter is irradiated in the direction surrounding the odor removing member, so that the ultraviolet light can be sufficiently irradiated to the entire odor removing member. By activating a photocatalyst, sufficient odor removal effect in a communication air path can be expected.

In addition, the term "light emission" of the ultraviolet light emitter means that the light generated by the light emission phenomenon of the ultraviolet light emitter itself by receiving ultraviolet light from the light source is emitted from the ultraviolet light emitter to the outside and from the light source to the ultraviolet light emitter. Ultraviolet rays are introduced from the ultraviolet light emitter to the outside. When ultraviolet light is generated by the light emission phenomenon of the ultraviolet light emitter itself, the ultraviolet light emitter itself is formed of a material that receives ultraviolet light and emits ultraviolet light, or a material that emits ultraviolet light by receiving ultraviolet light in a light transmitting material An ultraviolet light emitter may be formed by forming an ultraviolet light emitter or by applying an ultraviolet light emitting layer to an outer surface of the ultraviolet light emitter. In addition, when ultraviolet rays introduced into the ultraviolet light emitter from the light source are emitted from the ultraviolet light emitter to the outside, the ultraviolet light emitter can be formed of a light transmissive material. In this case, in order to improve irradiation efficiency, time signal processing may be performed on the outer peripheral surface.

In addition, the term "wraps" also includes a case in which the ultraviolet rays are sufficiently irradiated to the entire odor removing member even when completely enclosed or incomplete, and a sufficient odor removing effect in the communication air passage can be obtained by activating the photocatalyst. I shall do it.

The present invention is based on the prior-claimed Japanese application: Patent Application No. 2004-159240 (filed May 28, 2004) and Patent Application 2004-221142 (filed July 29, 2004). It is taken in this application specification with reference to.

In the dust collecting chamber 21, dust collecting bags F, such as a paper-pack filter, are attached, and dust collected by the dust collecting hose 12 is captured by this dust collecting bag F. As shown in FIG. Since this structure is well known, its detailed description is omitted. The dust collecting bag F is subjected to a photocatalytic treatment.

The cover 30 is provided so as to cover the opening of the dust collecting chamber 21 and is provided above the dust collecting chamber 21. In addition, the cover 30 is provided with a handle 30a protruding forward.

Moreover, the window 31 is formed in the cover 30 at the part which faces the dust collecting chamber 21 which is the internal space formed in the cleaner main body 11 (refer FIG. 4). This window 31 is an opening formed in the lid 30.

As shown in FIG. 4, the cover 30 is provided with a transparent window cover 33 on the outside so that the cover 30 can be freely attached and detached, and the window cover 33 covers the window 31 of the cover 30. This is substantially the same as when the window cover is directly provided on the window 31.

On the front side of the window cover 33, a finger hook portion 33a for hanging a finger when lifting upward is formed. Moreover, this window cover 33 is fitted in the annular holding recessed part 32d provided in the outer peripheral part of the window 31, and is attached.

Moreover, the holding | maintenance projection 32a is provided in the front side in the peripheral part of the dust collection chamber 21 side of the window 31, and the holding rib 32b is provided in the rear side.

The holding | maintenance projection 32a is provided in the position separated from the window 31 by the predetermined distance downward, and is extended in the left-right direction (width direction which is a direction orthogonal to a front-back direction) of the vacuum cleaner main body 11. And the front end of this holding | maintenance projection 32a is formed in R shape as shown in FIG.

On the other hand, the holding ribs 32b are provided in plural numbers at predetermined intervals in the left and right directions (width directions) of the cleaner main body 11, and as shown in FIG. 6, the width (length in the front and rear directions) is upward. It is long. Moreover, the holding recessed part 32c is formed in the upper part of the front end of the holding rib 32b, ie, in the vicinity of the window 31. As shown in FIG.

Then, the photocatalyst body (odor removal structure; 40) is held so as to be freely attached to the holding protrusions 32a and the holding ribs 32b to face the window 31, and at the same time, a dust collecting chamber (communication air passage; 21). Is placed on.

As shown in FIG. 2A, the photocatalyst 40 includes a photocatalyst filter (odor removal member) 41 and a frame 42 holding the photocatalyst filter 41.

The photocatalyst filter 41 is formed by alternately overlapping a photocatalyst sheet (photocatalyst member) 41a containing a photocatalyst material and a bamboo charcoal sheet 41b containing a bamboo charcoal (bamboo char) material. Here, the photocatalyst sheet 41a is bent in a wave form, and the photocatalyst filter 41 has a honeycomb structure (see FIG. 2B).

The frame 42 includes an annular holding frame (ultraviolet light emitter) 42a made of a transparent resin surrounding the photocatalyst filter 41, and a plurality of stacked frames 42b placed over the lower portion of the holding frame 42a. ) The photocatalyst filter 41 is disposed in the holding frame 42a so that the hole of the honeycomb structure extends in the vertical direction, and is stacked on the stacking frame 42b.

In addition, the holding frame 42a is annularly formed from a transparent acrylic member, and the time signal processing etc. are performed on the outer peripheral surface. As a result, when ultraviolet rays are irradiated from a part of the holding frame 42a to the inside, ultraviolet rays are emitted from the whole holding frame 42a to emit ultraviolet rays.

Moreover, as shown in FIG. 5 and FIG. 6, the engaging protrusion part 43 which protruded outward is provided in the upper part of the outer peripheral surface of the holding frame 42a over the perimeter. The engaging projection 43 of the front retaining frame 42a is engaged with the retaining projection 32a of the cover 30 so that it can be detached freely, and the engaging projection 43 of the rear retaining frame 42a is engaged. The photocatalyst 40 is attached to the lid 30 so that the lid 30 can be freely attached to and detached from the recess 32c of the retaining rib 32b.

Moreover, when the buffer member 44 is provided in the upper end surface of this holding frame 42a, and the photocatalyst 40 was attached to the lid | cover 30 by this buffer member 44 of the window 31, The direct contact of the frame body 42 with the main edge is prevented.

As shown in Fig. 4, a light source (ultraviolet light emitting source) 50 which emits ultraviolet rays which is preferable to be brought into close contact with the engaging projection 43 of the holding frame 42a is attached to the cover 30, and this light source 50 The terminals 51a and 52a are connected to the lead wires 51 and 52 connected to the (). As this light source 50, an ultraviolet lamp etc. are used.

In addition, the terminals 51a and 52a are attached to the terminal block 53 made of resin, and the terminal block 53 is held by the bracket 54 attached to the tip end of the lid 30 as shown in FIG. .

In addition, as illustrated in FIG. 3B, terminals 51b and 52b exposed to the upper surface are attached to the front end of the main body case 20. In addition, when the lid 30 is closed as shown in FIG. 3A, the terminals 51a and 52a of the lid 30 come into contact with the terminals 51b and 52b of the main body case 20 as shown in FIG. 3B.

These terminals 51b and 52b are connected to the control circuit 55 which has a power supply as shown in FIG. In addition, switches 13b, S1, S2, and S3 of the operation panel 13a are connected to the control circuit 55, and an electric blower 22 and a light source 50 are connected.

[Action]

Next, the operation of the vacuum cleaner having such a configuration will be described.

When the switch S1 or switch S2 provided in the handle operation pipe 13 is inserted, the control circuit 55 drives the electric blower 22. When the electric blower 22 is driven, suction negative pressure is generated, and the suction chamber 15 of the suction port 15 is not shown through the dust collecting chamber 21, the dust collecting hose 12, the handle operating pipe 13, and the extension pipe 14. Suction negative pressure. The suction negative pressure sucks in the dust and air on the surface to be cleaned from the suction opening of the suction chamber provided on the bottom surface of the suction port 15, through the extension pipe 14, the handle operating pipe 13, and the dust collecting hose 12. It is sucked into the dust collecting chamber 21 of the cleaner main body 11.

The dust sucked into the dust collecting chamber 21 is collected in the dust collecting bag F installed in the dust collecting chamber 21, and the air is sucked into the electric blower 22 in the electric motor chamber, and the exhaust of the cleaner main body 11 is not shown. Exhaust from the hole.

On the other hand, bacteria, such as dust and air, flow into the dust collecting chamber 21 to emit odor components such as ammonia and acetaldehyde from the dust collecting bag F and the like. This odor component is decomposed and deodorized by the photocatalyst filter (deodorant member) 41 of the photocatalyst body 40 provided in the lid 30 located above the dust collecting chamber 21. The bacteria themselves are also sterilized and decomposed by the photocatalyst filter (odor removal member) 41.

In addition, the structure by which the odor component etc. decompose | disassemble by this photocatalyst filter (odor removal member) 41 is as follows.

The photocatalyst material possessed by the photocatalyst sheet 41a of the photocatalyst filter (odor removal member) 41 is, for example, titanium dioxide (TIO ₂ ).

When light (ultraviolet rays) reach this titanium dioxide, electrons stick out from the surface to form a positively charged hole called a hole. These holes have a strong oxidizing power and are intended to be electrically stable by taking electrons from surrounding organic matter.

In this way, the organic matter deprived of electrons is decomposed by the redox effect of titanium dioxide, and finally, carbon dioxide, water, and the like are emitted into the atmosphere. In addition, the bamboo charcoal sheet 41b has adsorption power and can adsorb odor components.

Here, since the photocatalyst filter (odor removal member) 41 is provided along the window 31 formed in the lid 30, the photocatalyst filter (odor removal member) can be sufficiently touched by the light (ultraviolet rays) incident from the window 31, resulting in a high deodorizing effect. You can get it.

Moreover, since the photocatalyst filter 41 is provided in the frame body 42 so that the hole of the honeycomb structure may extend in an up-down direction, the odor component passes through and deodorizes between the photocatalyst sheet 41a and the bamboo charcoal sheet 41b. It can excite the action.

In addition, the air introduced into the dust collecting chamber 21 rarely passes through the photocatalyst filter (deodorizing member) 41 installed along the window 31 of the lid 30 and is sucked into the dust collecting chamber 21. It is almost impossible for the dust to adhere to the photocatalyst filter (odor removal member) 41.

And since this photocatalyst filter (odor removal member) 41 is attached to the lid | cover 30 so that it can be attached and detached freely, even if dust adheres to the photocatalyst filter (odor removal member; 41), it will be easy. Thus, the photocatalyst 40 provided with the photocatalyst filter (odor removal member) 41 can be peeled off and washed or replaced.

In addition, since the photocatalyst filter (odor removal member) 41 has a honeycomb type, external light introduced from the window 31 reaches the dust collecting bag F from the honeycomb-shaped gap so that ultraviolet light of the external light is photocatalyzed. It acts on the dust collecting bag F, and the odor component decomposes | disassembles by the photocatalytic process part of the dust collecting bag F. As shown in FIG.

On the other hand, when the light-emitting body lighting switch 13b is turned on, the control circuit 55 turns on the light source 50. Ultraviolet light emitted from the light source 50 is incident into the holding frame 42a to emit ultraviolet rays in the whole of the holding frame 42a to emit ultraviolet rays in the whole of the holding frame 42a.

Part of this ultraviolet light is irradiated to the photocatalyst filter (odor removal member) 41, and the odor component is decomposed by the photocatalyst filter (odor removal member) 41.

In addition, a part of the other ultraviolet rays is irradiated to the dust collecting bag F subjected to the photocatalyst treatment, whereby the odor component in the dust collecting bag F is decomposed.

In addition, since part of the ultraviolet rays are transmitted through the window 31 and radiated to the outside, the window 31 appears to shine in a blurry purple from the outside. Thereby, a user can know that the odor removal process in the dust collecting chamber 21 is performed. In particular, it can be seen that an odor removal treatment is performed at the time of use at night.

In addition, since the photocatalyst body 40 can be kept clean at all times, the decomposition action is not impeded by the dust adhering to the photocatalyst body 40, so that a sufficient deodorizing effect can be maintained for a long time.

In addition, since the photocatalyst 40 can be easily cleaned or replaced, the deterioration of the deodorizing effect can be prevented even when the photocatalyst filter 41 is exposed in the dust chamber 21. And since this photocatalyst filter 41 is exposed, a high deodorizing effect can be acquired.

In addition, during the daytime, external light is introduced from the window 31 to irradiate the ultraviolet light contained in the external light with the photocatalyst filter (deodorant member 41), the dust bag F, and the like to decompose the odor component. On the other hand, at night with little external light introduced from the window 31, the light source 50 emits light to emit ultraviolet light, thereby inducing ultraviolet light into the holding frame 42a to emit ultraviolet light from the whole holding frame 42a. The odor component is decomposed by the catalyst filter (odor removal member) 41, the dust bag F, and the like. Thus, by distinguishing between the ultraviolet rays included in the external light during the day and at night and the ultraviolet rays due to the light emission of the holding frame 42a, the odor in the dust collecting chamber 21 can be effectively decomposed without wasteful use of energy. have.

(Modification 1)

In the above-mentioned embodiment, although the time signal processing was performed to the outer peripheral surface of the holding frame 42a, an ultraviolet-ray was emitted from the whole holding frame 42a, However, it is not necessarily limited to this.

As shown in FIG. 8, the lens part 56 may be provided in the lower end of the holding frame 42a, and the ultraviolet-ray may be irradiated downward from this lens part 56. As shown in FIG. In this case, ultraviolet rays can be irradiated to the dust collecting bag F through the lens unit 56 at the bottom of the holding frame to decompose the malodorous component in the malodor bag.

(Modification 2)

In the embodiment described above, an example in which the holding frame 42a is an ultraviolet light emitter is shown, but is not necessarily limited thereto.

For example, you may comprise as FIG. 9, FIG. In FIG. 9, the window 31 is formed in an elliptical shape as shown in FIG. 10, and the cover projection portion 33a of the cross-sectional arc shape that is curved upwardly expands in a portion facing the window 31 of the window cover 33. As shown in FIG. ) Is formed. In addition, the front part of the cover projection part 33a becomes a recessed part 33b which is recessed downward as shown to FIG. 9, FIG.

The lid 30 is provided with a retention recess 32d extending in an annular manner along the window 31 as shown in FIG. This holding recessed portion 32d is formed between the inner and outer double annular flanges 32d1 and 32d2 which protrude upward along the window 31. The inner annular flange 32d1 has an annular standing part d1a and an annular inner protrusion part d1b which protrudes inward with respect to this annular standing part d1a.

Further, the edge 30b along the window 31 of the lid 30 has a very small protrusion amount from the annular standing portion d1a, and the annular inner protrusion d1b has a protrusion amount from the annular standing portion d1a. It is set large.

Between this annular inner projection d1b and the edge 30b along the window 31 of the lid 30, a cyclic ultraviolet light emitter 57 made of a transparent resin elastically bonded to the annular standing portion d1a is formed. Maintained. As shown in Figs. 9 to 11, the ultraviolet light emitter 57 protrudes in the annular light emitting portion (light emitter) 57a formed in a ring shape in advance and protrudes behind the annular light emitting portion 57a. It has a projection 57b for ultraviolet incidence.

At the rear end of the projection 57b, a light source (ultraviolet light source) 58 that emits ultraviolet rays is provided. This light source 58 is also controlled by the control circuit 55 shown in FIG. 7 in the same manner as in the above-described embodiment.

Then, the light source 58 is made to emit light, and the ultraviolet rays from the light source 58 are incident on the protrusions 57b to thereby enter the annular light emitting portions 57a to emit ultraviolet rays in the entirety. Ultraviolet rays emitted from the annular light emitting portion 57a are irradiated entirely from the upper circumference inclined to the photocatalyst filter 41 which is an odor removing member, and the odor is decomposed by the photocatalyst filter 41.

In addition, at this time, since the ultraviolet rays can be seen from the cover protrusion 33a, the operating state of the ultraviolet light emitter 57 can be confirmed.

(Modification 3)

In addition, the above-mentioned cover protrusion part 33a part can also be set as an ultraviolet-ray light emitter as shown in FIG. In this case, the leg part 33c may be provided in the cover part 33a, and the end surface of this leg part 33c may be made to require the light source 33d which emits an ultraviolet-ray. In this case, ultraviolet-ray is irradiated to the photocatalyst filter 41 from the circumference | surroundings in the whole cover part 33a.

(Modification 4)

In the embodiment described above, the ultraviolet light emitter 57 has been cyclically molded from the beginning, but it is not necessary to use the cyclically molded one.

That is, a transparent resin and linear light emitter is formed to be annularly curved between the annular inner projection d1b and the edge 30b along the window 31 of the lid 30, as shown in FIG. The ultraviolet light emitter 59 may be used. In this case, the first light source 60 and the second light source 61 can be directed to the respective ends 59a and 59b of the ultraviolet light emitter 59, respectively. As the ultraviolet light emitter 59, a flexible light guide having a structure in which an elastomeric material is filled in a cylindrical fluorine resin tube is used.

In this case, when the first light source 60 and the second light source 61 are light sources that emit ultraviolet light, the ultraviolet light incident into the ultraviolet light emitter 59 can be increased. In this case, the decrease in the amount of light at the center of the ultraviolet light emitter 59 can be prevented.

In addition, when the first light source 60 is used as a light source for emitting ultraviolet light and the second light source 61 is used as a light source for emitting visible light, for example, blue light, the first and second light sources 60 and 61 emit light at the same time. Ultraviolet light is emitted from the ultraviolet light emitter 59 as a whole, and blue visible light is emitted from the entire ultraviolet light emitter 59.

Since this blue visible light can be confirmed by the window 31, when blue visible light is seen by the window 31, it can visually confirm that ultraviolet-ray is emitted from the ultraviolet light emitter 59. As shown in FIG.

In addition, although the 2nd light source 61 was made into the light source which emits blue visible light, it is not necessarily limited to this. That is, the second light source 61 may be a light source that emits visible light other than blue.

In addition, the ultraviolet light emitter of the electric cleaner according to the embodiment of the present invention is a holding frame 42a which is held to surround the odor removing member. According to this configuration, when the holding frame 42a (ultraviolet light emitter) is emitted, the ultraviolet rays emitted from the holding frame 42a (ultraviolet light emitter) surround the odor removing member (photocatalytic filter 41). Since it is irradiated, an ultraviolet-ray can fully be irradiated to the whole odor removal member (photocatalyst filter 41), and sufficient odor removal effect in a communication air path (in the embodiment, the dust collecting chamber 21 is a part of a communication air path) can be expected.
