Detailed ways

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each embodiment, parts having the same structure, function, etc. as those of the previous embodiment are described with the same reference numerals, and detailed descriptions are omitted. In addition, this invention is not limited to these embodiment.

(Embodiment 1)

Fig. 1, Fig. 2, and Fig. 3 are respectively a transverse sectional view, a main part longitudinal sectional view, and a perspective view of an air cleaner according to Embodiment 1 of the present invention. This air cleaner has a housing 3 , a motor 4 , a cross flow fan 5 , a cover 6 , a filter unit 7 , a front panel 9 and a wall 11 .

An air inlet 1 and an air outlet 2 are respectively provided on the left and right sides of the vertically long housing 3 . That is, the suction port 1 and the discharge port 2 are provided on opposite sides with respect to the cross flow fan 5 . With such a structure, the airflow discharged from the exhaust port 2 will not be sucked into the air intake port 1 and circulated, resulting in a decrease in purification efficiency. A longitudinal cross-flow fan 5 is arranged in the casing 3 and driven by a motor 4 . The cross flow fan 5 extends in a direction perpendicular to the flow of air. A tongue portion 10 is provided on the cover 6 to surround a part of the cross flow fan 5 to form an intake flow and an exhaust flow. The vertically long filter unit 7 is provided on the intake flow side of the cover 6 and is composed of a dust collecting filter 22 and a deodorizing filter 23 . The dust collecting filter 22 is made of, for example, porous polyester or an electric dust collecting filter. In order for the cross flow fan 5 to function efficiently, it is preferable to use an electric dust collection filter. The deodorizing filter 23 is made of, for example, activated carbon enclosed in a nonwoven fabric bag.

The air path is formed from the filter unit 7 to the space portion 8 of the cross flow fan 5 . The cross section of the front panel 9 is formed in a convex arc shape, and the front panel 9 forms a part of the casing 3 . A wall 11 connects the front panel 9 and the tongue 10 of the cover 6 . The filter unit 7 , the front panel 9 and the wall portion 11 surround the space portion 8 . The housing 3 is formed by a front panel 9 and a rear panel 12 with a protruding rear. The filter unit 7 is arranged between the front panel 9 and the rear panel 12 in a close contact (close contact) state.

In this configuration, when the air cleaner is operated, the cross flow fan 5 is driven by the motor 4 . Thus, the polluted air sucked in through the air inlet 1 is purified by the filter unit 7 . The purified air then enters the space portion 8 . Through the space portion 8 , the airflow passing through the filter unit 7 is introduced toward the cross flow fan 5 and the tongue portion 10 of the cover 6 without being disturbed. The purified air is then discharged from the exhaust port 2.

Thus, according to the present embodiment, the space portion 8 is surrounded by the filter unit 7 , the front panel 9 , and the wall portion 11 . That is, a free space 8 is provided on the suction side of the cross flow fan 5 . Therefore, the airflow passing through the filter unit 7 is introduced in the direction of the cross flow fan 5 and the tongue portion 10 of the cover 6 without being disturbed. Thereby, fan efficiency can be ensured suitably, and the air volume of an air cleaner can be ensured.

In addition, the cross section of the front panel 9 is preferably formed in an arc shape with a convex front. Thereby, the space part 8 which is the air path to the cross flow fan 5 can be enlarged. In addition, the airflow follows the curved surface of the front panel 9 and flows quickly.

In addition, preferably, the housing 3 is formed by a front panel 9 protruding from the front and a rear panel 12 protruding from the rear, and the filter unit 7 is disposed between the front panel 9 and the rear panel 12 in a close-fit state. With this structure, the polluted air inhaled from the suction port 1 provided at one end of the casing 3 is purified by the filter unit 7 arranged obliquely in the casing 3 in the horizontal section, and is discharged from the Exhaust port 2 at the other end exhausts. Therefore, even if the thickness dimension of the left and right ends of the housing 3 is reduced, the passage area of the filter unit 7 can be ensured, and the air purification efficiency can be maintained. Therefore, not only the shape of the casing 3 is slim, but also the air cleaning function can be realized with a simple structure.

Also as shown in FIG. 1 , the filter unit 7 is preferably arranged in the following manner in cross section. That is, with respect to the reference line 14 connecting the tongue portion 10 of the cover 6 and the rotation shaft 13 of the cross flow fan 5, the angle α formed by the direction 15 perpendicular to the direction in which the air passes through the filter unit 7 is set to 90 degrees. or above. Thereby, the left-right width of the space part 8 can be enlarged, and the airflow which passed the filter unit 7 can be introduced to the direction of the cross-flow fan 5 and the tongue part 10 more smoothly.

In addition, preferably, the first end 7A of the filter unit 7 is arranged near the extension line of the reference line 14 , and the second end 7B opposite to the first end 7A is brought into close contact with the front panel 9 . In this air cleaner, the start position of the suction region of the cross flow fan 5 is a symmetrical position of the tongue 10 with respect to the rotation axis 13 . The suction force near the start position of the suction area of the cross flow fan 5 is weak. Therefore, by bringing the first end 7A of the filter unit 7 close to the start position of the suction area, the reduction in fan efficiency becomes small. In addition, air leakage can be prevented by bringing the second end 7B into close contact with the front panel 9 . Furthermore, in the range where the suction force of the cross-flow fan 5 is relatively strong, the filter unit 7 is arranged gradually away from the cross-flow fan 5 so that it does not become an obstacle to the air flow. Therefore, the suction force of the cross flow fan 5 can be increased. It is preferable to secure the space portion 8 after passing through the filter unit 7 by such a structure.

In addition, in the air cleaner according to the present embodiment, the longitudinal dimension of the cross flow fan 5 is arranged substantially in the vertical direction. With this structure, the installation area becomes small.

(Embodiment 2)

Fig. 4 is a cross-sectional view of an air cleaner according to Embodiment 2 of the present invention. In the air cleaner according to the present embodiment, the cross-sectional shape of the wall portion 11A is an arc shape, and the radius of curvature thereof is configured to be smaller than the radius of curvature of the front panel 9 . Other configurations are the same as those of Embodiment 1.

In the above configuration, when the air cleaner is operated, air is sucked in from the intake port 1 , and the air cleaned by the filter unit 7 enters the space 8 . Here, the radius of curvature of the wall portion 11A is smaller than the radius of curvature of the front panel 9 . Therefore, the direction of the air entering the space portion 8 is smoothly changed toward the tongue portion 10 of the cover 6 . Therefore, the air flow can flow into the cross flow fan 5 without stagnation. Therefore, the air supply efficiency of the air cleaner can be further improved.

(Embodiment 3)

Fig. 5 is a cross-sectional view of an air cleaner according to Embodiment 3 of the present invention. In this air cleaner, with respect to the reference line 14 of the tongue portion 10 of the connection cover 6 and the rotation shaft 13 of the cross flow fan 5, the angle formed by the direction 15 perpendicular to the direction in which the air passes through the filter unit 7 is made β constitutes less than 90 degrees. Other than that, the basic structure is the same as that of Embodiment 1.

In this structure, the filter unit 7 becomes closer to the side of the cross flow fan 5 . As a result, the end of the front panel 9A and the end of the rear panel 12A can be brought closer to the side of the cross flow fan 5 . Therefore, the width A of the casing 3A can be made smaller than the width B of the casing 3 of the first embodiment.

Thus, by making the angle β less than 90 degrees, the filter unit 7 can be arranged close to the center of the casing 3A. Therefore, the width A of the casing 3A can be reduced, and the installation area can be further reduced.

(Embodiment 4)

Fig. 6 is a cross-sectional view of an air cleaner according to Embodiment 4 of the present invention. In this air cleaner, the front panel 9B is provided with the intake port 1A as the first intake port, and the rear panel 12B is provided with the intake port 1B as the second intake port. The intake ports 1A and 1B are arranged at opposite ends of the exhaust port 2 . Other configurations are the same as those of Embodiment 1.

In the above configuration, when the air cleaner is operated, polluted air is sucked in from the air inlets 1A and 1B by the cross flow fan 5 . Since the air intake ports 1A and 1B are provided at the front and rear two positions of the casing 3B in this way, the area of the air intake port constituted by the air intake ports 1A and 1B increases, and the air volume increases. In addition, the direction of air suction is also expanded forward and backward, so that the air suction range of the air purifier can be expanded.

(Embodiment 5)

Fig. 7 is a cross-sectional view of an air cleaner according to Embodiment 5 of the present invention. In this air cleaner, the second end 7B of the filter unit 7 is in close contact with both the front panel 9 and the rear panel 12 .

In this structure, the second end 7B of the filter unit 7 is arranged corresponding to the portion where the front panel 9 and the rear panel 12 are in close contact. Therefore, the filter unit 7 is formed in the longest state compared with the first embodiment. The cleaning area of the polluted air by the filter unit 7 is thus increased.

In this way, by making the second end 7B of the filter unit 7 adhere to both the front panel 9 and the rear panel 12, the limited installation space in the housing 3 can be effectively utilized. That is, the filter unit 7 having a large width can be provided, and the cleaning efficiency of the filter unit 7 can be improved. In addition, the air resistance of the filter unit 7 can be reduced, thereby reducing the load on the cross flow fan 5 and increasing the air blowing volume.

(Embodiment 6)

Fig. 8 is a cross-sectional view of an air cleaner according to Embodiment 6 of the present invention. 9 and 10 respectively show a front perspective view and a rear perspective view of the air cleaner. Fig. 11 is a perspective view showing a state in which the deodorizing filter and the dust collecting filter are taken out of the air cleaner. Fig. 12 is a cross-sectional view showing a guide portion for taking out the deodorizing filter.

In this embodiment, an air intake grill 36 that covers the air intake port 1 and is detachably attached to the housing 3 is provided on the back side of the housing 3 . In addition, the deodorizing filter 23 as the first filter and the dust collecting filter 22 as the second filter constituting the filter unit 7 are arranged obliquely with respect to the casing 3 so as to be removable in an oblique direction. In addition, deodorization filter 23 and dust collection filter 22 are provided so that they can be attached and detached separately. The insertion port 39 of the deodorizing filter 23 provided in the case 3 is provided with a guide portion 40 that contacts the side surface of the deodorizing filter 23 and serves as a guide portion. The planar portion of the guide portion 40 is formed large as shown in FIGS. 8 and 12 . Other basic configurations are the same as those of the first embodiment.

The life of the deodorizing filter 23 is generally shorter than the life of the dust collecting filter 22 . Therefore, only the deodorizing filter 23 is often replaced first. At this time, the suction grille 36 that is detachably arranged on the housing 3 is removed, and the deodorizing filter 23 is taken out obliquely on the back side, and then a new deodorizing filter 23 is installed, and the suction grille is installed. Grid 36. In addition, when cleaning or replacing the dust collection filter 22, the suction grill 36 is detached, and then the dust collection filter 22 is taken out and cleaned or replaced.

As shown in the present embodiment, it is preferable to install the intake grill 36 on the back side of the housing 3, and the filter unit 7 is installed obliquely, and the intake grill 36 can be installed in the inclined direction by detaching the intake grill 36. Each filter 22, 23 is attached and detached. In this way, by taking out the filter unit 7 obliquely rearward from the back of the casing 3, the limited body space can be effectively used flexibly, and maintenance can be easily performed. In addition, compared with a structure in which a detachable housing or the like is provided on the front surface or the top surface, and the filter unit 7 is taken out from the front surface or the top surface of the casing 3, it is superior in design.

In addition, it is preferable that the dust collection filter 22 and the deodorization filter 23 can be attached and detached separately. When the lives of the dust collecting filter 22 and the deodorizing filter 23 are different, they can be taken out from the casing 3 and cleaned or replaced separately, and maintainability is also improved.

In addition, preferably, on the insertion port 39 of the deodorizing filter 23 provided on the housing 3, a guide part 40 that contacts the side surface of the deodorizing filter 23 and becomes a guide part is provided, and the guide part 40 The planar portion is formed very large. With this configuration, the deodorizing filter 23 can be easily slid, and detachability to the casing 3 is improved.

Moreover, it is preferable to provide the 1st handle part 42 to the deodorization filter 23, and to provide the 2nd handle part 43 to the dust collection filter 22, as shown in FIG. Thereby, deodorization filter 23 and dust collection filter 22 can be easily taken out.

In addition, in this embodiment, an example in which the deodorizing filter 23 is used as the first filter and the dust collecting filter 22 is used as the second filter has been described, but this embodiment as described later may also be used. Alternative filter configurations as described.

(Embodiment 7)

Fig. 13 is a rear perspective view of the air cleaner according to Embodiment 7 of the present invention. In the present embodiment, a first handle portion (hereinafter referred to simply as a handle portion) 42 for taking out from the casing 3 is provided on the deodorizing filter 23A as the first filter. Moreover, the 2nd handle part (referred to simply as a handle part hereinafter) 43 is provided in the dust collection filter 22A which is a 2nd filter. The deodorizing filter 23A is adjacent to the dust collection filter 22A. Then, the blocking portion (hereinafter referred to simply as the blocking portion) 41 is taken out and installed on the handle portion 42 . The blocking portion 41 is a protrusion superimposed on the handle portion 43 . Other configurations are the same as those of Embodiment 6.

In this structure, the stopper part 41 provided in the handle part 42 of the deodorization filter 23A is superimposed on the handle part 43 of 22 A of dust collection filters. Therefore, the dust collection filter 22A cannot be taken out before the deodorization filter 23A. That is, only the dust collection filter 22A cannot be taken out individually before the deodorization filter 23A.

As mentioned above, generally, the life of the deodorizing filter 23A is shorter than that of the dust collecting filter 22A, and the frequency of taking out the deodorizing filter 23A from the casing 3 is higher. In the air cleaner of this embodiment, even if the user tries to take out only the dust collection filter 22A by mistake, the blocking part 41 stops it. Therefore, it is possible to prevent a user's taking-out mistake in advance.

In addition, when an electric dust collecting filter is used as the dust collecting filter 22A, a resistor for discharging the charge charged in the dust collecting filter 22A is provided inside the dust collecting filter 22A in many cases. In this case, after the power supply is cut off, it takes several seconds to completely discharge the charge. If the deodorizing filter 23A can be taken out before the dust collection filter 22A is taken out, the discharge time can be ensured. Therefore, the user can perform maintenance of the dust collection filter 22A more safely.

In addition, since the stop portion 41 is provided on the handle portion 42 of the deodorizing filter 23A, when the deodorizing filter 23A and the dust collecting filter 22A are taken out from the housing 3, the deodorizing filter 23A must be taken out first. Then take out the dust filter 22A. Therefore, the user can easily judge the order of taking out the deodorizing filter 23A and the dust collecting filter 22A from the casing 3 .

In addition, in this embodiment, the blocking part 41 is provided in the handle part 43, but it may be provided in the deodorization filter 23A itself. That is, on the insertion port 39 side of the filter unit 7 shown in FIG. That's it.

The handle part 46 is provided on the frame 45 and is used when taking out the deodorant 44 from the frame 45 . Furthermore, as shown in FIG. 14 , the handle portion 46 is also used when taking out the deodorizing filter 23B from the casing 3 .

In this way, the handle part 46 preferably serves as both a handle part for attaching and detaching the deodorizing filter 23B to the case 3 and a handle part for taking the deodorant 44 out of the frame 45 . Thereby, it is not necessary to use two types of handles for the deodorizing filter 23B, the component structure becomes simple, and the mold manufacturing cost can be reduced. In addition, since there are two types of handles on the deodorizing filter 23B, it is possible to prevent the user from using the handles by mistake.

Moreover, it is preferable that the handle part 46 is overlapped with the dust collection filter 22B which is a 2nd filter, and is comprised. At this time, the handle portion 46 functions as a removal prevention portion that prevents the dust collection filter 22B from being removed earlier. Therefore, the same effect as that of Embodiment 7 can be obtained.

Other configurations are the same as those of Embodiment 6.

In this structure, until the deodorizing filter 23C is taken out from the casing 3 using the handle part 42A, the handle part 43A of the dust collection filter 22C is hidden behind the handle part 42A. Therefore, the user cannot grasp the handle portion 43A until the deodorizing filter 23C is taken out from the casing 3 . Therefore, it is possible to prevent the user from unintentionally performing a take-out operation. At this time, 42 A of handle parts also function as a removal prevention part which prevents 22 C of dust collection filters from being taken out earlier.

In addition, in a certain air cleaner, a plurality of filters such as a pre-filter, a high-voltage ionization unit, an electric dust collector, and a deodorizing filter are arranged vertically in the ventilation direction. In such an air cleaner, as in Embodiments 7 to 9, if, for example, a deodorizing filter is provided with a removal prevention part that prevents the removal of other filters, the user can safely attach and detach each filter from the side. filter.
