Description

Air Purifier

The present invention relates to an air cleaner having a deodorizing unit that regenerates deodorizing ability by heating.

In the air purifier, for example, the air sucked into the main body casing is driven by the deodorizing filter by the driving of the air blower provided in the main body casing, and the odor component contained in the air is adsorbed to the deodorizing filter. The deodorizing ability of the deodorizing filter is regenerated by heating the deodorizing filter. In the air cleaner, the deodorizing filter is provided to be rotatable, and the heating portion is disposed so as not to be in contact with the deodorizing filter but covers a part thereof (for example, refer to Japanese Patent Laid-Open Publication No. Hei 10-277365 ).

The air cleaner described in Japanese Laid-Open Patent Publication No. Hei 10-277365 has an air flow passage for guiding air taken into the main body casing from the air intake port to the air outlet. A prefilter, a catalyst structural member, and a blower fan are disposed in this order along the direction from the air intake port toward the air blow port. The catalyst structural member includes: a disk-shaped adsorption plate (corresponding to a deodorizing filter) that adsorbs an odor component in the air; and drives the adsorption plate to rotate Moving motor (drive unit); and cover. The motor is supported by the bracket on the upper wall of the air flow passage. The output shaft of the motor is engaged with the center portion of the suction plate. The cover is fixed to the upper wall of the air flow path and covers a part of the adsorption plate. The cover covers a front portion and a back portion of the suction plate. On the inner wall surfaces of the front side and the back side of the cover, a catalyst plate is disposed to decompose the odor component, and a heat generating body (corresponding to the heating portion) is provided to heat the adsorption plate and the catalyst plate.

If the air cleaner drives the blower fan, air is taken in from the air intake port to the air passage. The prefilter is used to remove dust contained in the air. Thereafter, the air reaches the adsorption plate. The odor component of the air is adsorbed when the air passes through the portion of the adsorption plate exposed from the cover. Thereby, the purified air is again blown out from the air outlet to the room. On the other hand, a part of the adsorption plate covered by the cover is heated by the heating element. Thereby, the odor component adsorbed by this part is detached from the adsorption plate. The odor component that has been detached is decomposed by a catalyst plate that is also heated by the heating element. In addition, the suction plate is rotated by a predetermined angle (for example, 90 degrees) every fixed time by the motor.

In the air cleaner described above, a part of the adsorption plate covered by the cover is heated by the heat generating body to regenerate the deodorizing ability of the adsorption plate. Further, the air is deodorized by the portion of the adsorption plate exposed from the cover. Therefore, the air purifier consumes less power than the air cleaner that heats the entire adsorption plate by the heat generating body formed corresponding to the shape of the adsorption plate. Further, in the above air cleaner, the adsorption plate is covered only by the cover a part of. Therefore, the air odor reducing filter of the air cleaner has a smaller air resistance than an air cleaner having a heat generating body formed corresponding to the shape of the suction plate.

In the air cleaner described in Japanese Laid-Open Patent Publication No. Hei 10-277365, in order to rotate the suction plate, it is necessary to provide a gap between the suction plate and the cover. Therefore, there is a problem that heat generated by the heat generating body diffuses from the gap to the outside of the cover.

When the front side outer casing 23ea and the rear side outer casing 23eb are joined, the windshield 23y separates the space formed by the front side outer casing 23ea and the rear side outer casing 23eb from the outer space. Thereby, the windshield 23y prevents or suppresses the flow of air into the filter regeneration portion 23f, and suppresses the inflowing air from cooling the front side heat dissipation plate 23ca and the back side heat dissipation plate 23cb.

Similarly to the front side outer casing 23ea, the back side casing 23eb is formed in a substantially triangular shape which is larger than the back side heat sink 23cb and the heat insulator 23d by a synthetic resin material. The back side casing 23eb has a heating portion accommodating portion 23ed, a back side cover portion 23v as a through hole covering portion, a pair of back side first flanges 23w, and a pair of back side second flanges 23x. The back side casing 23eb is disposed to cover a part of the back side of the deodorizing filter 23a.

The heating unit housing portion 23ed has a bottomed case formed of the bottom surface and the side surface. The heating unit accommodating portion 23ed is formed to be able to accommodate the back side heat sink 23cb and the heat insulator 23d. shape. The heat insulator 23d is disposed between the back side heat sink 23cb and the heating unit housing portion 23ed.

The back side cover portion 23v and the heating portion accommodating portion 23ed are integrally formed on the side surface opposite to the second joint portion 23ce of the back side heat sink 23cb. That is, the back side cover part 23v is formed in the side surface of the heating part accommodating part 23ed.

The back side cover portion 23v is formed in a disk shape corresponding to the center hole (through hole) 23ad. For example, the back side cover portion 23v may have a disk shape having the same size as the center hole 23ad or slightly larger than the center hole 23ad.

The pair of back side first flanges 23w and the pair of back side second flanges 23x are integrally formed with the pair of side faces of the heating portion accommodating portion 23ec, and the pair of side faces of the heating portion accommodating portion 23ec and the back side heat dissipating plate 23cb The pair of oblique sides connecting the second joint portion 23ce and the first joint portion 23cd are opposed to each other. In other words, the pair of back side first flanges 23w and the pair of back side second flanges 23x are formed on the second side face 23edc and the third side face 23edd of the heating unit accommodating portion 23ec.

As shown in Fig. 9, the heights of the pair of front side first flanges 23t (the distance from the surface of the deodorizing filter 23a) are different from the heights of the front side cover portion 23s and the pair of front side second flanges 23u by the step size L. . Further, the height of the pair of back side first flanges 23w is different from the height of the back side cover portion 23v and the pair of back side second flanges 23x by the step size L. Further, a pair of front side first flanges 23t, a pair of front side second flanges 23u, front side cover portions 23s, The pair of back side first flanges 23w, the pair of back side second flanges 23x, and the back side cover portions 23v are flange portions of the air cleaner 1 of the present embodiment. Further, the flange portion is a pair of front side first flanges 23t, a pair of front side second flanges 23u, front side cover portions 23s, a pair of back side first flanges 23w, and a pair of back side second protrusions The edge 23x and the back side cover portion 23v are heat diffusion suppressing portions that suppress heat from being diffused from the heating portion housing portion 23ec and the heating portion housing portion 23ed. For example, the thermal diffusion suppressing portion suppresses the heat generated by the heating portion from being diffused from the heating portion housing portion by the air flowing through the ventilation passage and passing through the deodorizing filter.

The filter regeneration unit 23f having the above-described members is assembled in the following manner. First, the PTC heater 23b is housed in the heater case 23p. The heater case 23p is fixed to the heater arrangement surface 23cab of the front side heat dissipation plate 23ca by a screw or the like. Next, the second joint portion 23ce of the back side heat sink 23cb is disposed in the center hole 23ad of the deodorizing filter 23a. Thereafter, the first joint surface 23cda and the second joint surface 23cea of the back side heat sink 23cb are joined to the filter facing surface 23caa of the front side heat sink 23ca.

Further, (A) of Fig. 9 is a view as seen in the direction of the arrow C of Fig. 8(A). Fig. 9 (B) is a Z-Z sectional view of Fig. 8 (A). Further, (A) of FIG. 10 is a schematic view when the main portion N of FIG. 6 is viewed from the lateral direction. (B) of FIG. 10 is a schematic view of the main part M of FIG. 6 as seen from the lateral direction. As shown in FIG. 8 to FIG. 10 described above, when the deodorizing filter 23a and the filter reproducing portion 23f are assembled, as described in detail below, the deodorizing filter 23a and the front side heat sink 23ca and the back side heat sink are provided. The gap between the 23cb and the gap between the deodorizing filter 23a and the front side outer casing 23ea and the back side outer casing 23eb are set to a predetermined size, and the deodorizing filter 23a is positioned in the filter reproducing unit 23f.

First, the positioning of the deodorizing filter 23a, the front side heat sink 23ca, and the back side heat sink 23cb will be described with reference to Figs. 7 and 10 . As described above, in the back side heat sink 23cb, the height H between the filter facing surface 23cca of the main body portion 23cc and the first joint surface 23cda and the second joint surface 23cea is larger than the first gear of the deodorizing filter 23a. 23ac has a thickness dimension T1. Further, as shown in FIG. 10(B), when the outer roller 23no is fitted to the third shaft 23q, the size between the front side second flange 23u and the upper flange 23nc of the front side outer casing 23ea, and the back surface The dimension between the second flange 23x on the back side of the side casing 23eb and the lower flange 23nd is set to P1, respectively. In addition, outside When the first gear 23ac of the deodorizing filter 23a is attached between the upper flange 23nc and the lower flange 23nd of the side roller 23no, the size between the first gear 23ac and the upper flange 23nc and the lower flange 23nd is set separately. Is P2 (=(S-T1)/2). At this time, the movable range of the outer side roller 23no in the front-rear direction is set to the range defined by the dimension P1 by the front side outer casing 23ea and the back side outer casing 23eb. Further, the upper flange 23nc and the lower flange 23nd are used to set the movable range of the deodorizing filter 23a in the front-rear direction to the range determined by the dimension P2.

In addition, although the illustration is omitted, the positional relationship between the inner side roller 23ni and the front side outer casing 23ea and the back side outer casing 23eb, and the positional relationship between the inner side roller 23ni and the deodorizing filter 23a are the same as those of the outer side roller 23no.

On the other hand, as shown in FIG. 10(A), the size P3 between the surface of the filter main body of the deodorizing filter 23a and the filter facing surface 23caa of the front side heat radiating plate 23ca, and the deodorizing filter 23a The dimension P3 between the filter main body surface and the filter opposing surface 23cca of the main body portion 23cc of the back side heat dissipating plate 23cb is set to satisfy P3 (= (H - T2) / 2). Here, as shown in FIG. 10(A), the dimension S, the thickness dimension T1, the thickness dimension T2, the height dimension H, and the front side casing are determined such that the relationship of the sizes P1, P2, and P3 becomes P1+P2<P3. The size of the space between the front side second flange 23u of the 23ea and the back side second flange 23x of the back side casing 23eb. Thus, when the deodorizing filter 23a is rotated by the driving portion 23h, the deodorizing filter 23a does not come into contact with the front side heat sink 23ca and the back side heat sink 23cb, and can be stably rotated.

Next, the positioning of the deodorizing filter 23a, the front side outer casing 23ea, and the rear side outer casing 23eb will be described with reference to Figs. 9 and 10 . As shown in Fig. 9, the step size between the first gear 23ac and the filter surface (front and back) provided on the outer peripheral portion of the deodorizing filter 23a, and the coverage provided on the inner circumference of the deodorizing filter 23a The step size between the portion 23ae and the filter surface (front and back) is set to the same step size L (= (T1 - T2) / 2, for example, 1.5 mm). In cooperation with this, the step size between the front side first flange 23t and the front side cover portion 23s and the front side second flange 23u, and the back side first flange 23w and the back side cover portion 23v and the back side second The step size between the flanges 23x is also set to L, respectively.

Further, as described above, the size between the front side second flange 23u of the front side outer casing 23ea and the upper flange 23nc of the outer side roller 23no, and the back side second flange 23x of the back side outer casing 23eb and the outer side roller 23no The size between the lower flanges 23nd is set to P1. Further, the dimension between the first gear 23ac and the upper flange 23nc and the lower flange 23nd is set to P2. The movable range of the outer side roller 23no in the front-rear direction is set to the range defined by the dimension P1 by the front side outer casing 23ea and the back side outer casing 23eb. Further, the upper flange 23nc and the lower flange 23nd are used to set the movable range of the deodorizing filter 23a in the front-rear direction to the range determined by the dimension P2.

On the other hand, the size of the space between the front side surface of the deodorizing filter 23a and the front side first flange 23t of the front side casing 23ea, deodorizing filtering The size of the gap between the back side surface of the rear surface side cover 23ab and the back side first flange 23w of the back side case 23eb, the front cover side portion 23s of the front side case 23ea, and the back side cover portion 23b of the back side case 23eb. The size of the space between the first gear 23ac and the front side second flange 23u of the front side outer casing 23ea and the back side second flange 23x of the back side outer casing 23eb to be separated from the deodorizing filter 23a The shape of the inner roller 23ni, the outer roller 23no, and the shape and arrangement of the three third shafts 23q are determined such that the inner diameter to the outer diameter are within a predetermined interval dimension D (for example, 1.0 mm). The predetermined interval size D is a size in which the deodorizing filter 23a does not easily come into contact with the filter regenerating portion 23f (the front side outer casing 23ea and the rear side outer casing 23eb) when it is rotated. Further, the predetermined interval size D is such that the heat generated by the PTC heater 23b is prevented from diffusing to the outside of the casing 23e, and the air passing through the deodorizing filter 23a can be prevented from entering the inside of the filter reproducing portion 23f.

Specifically, as shown in FIG. 10(B), the dimension S, the thickness dimension T1, the thickness dimension T2, the height dimension H, and the front side are determined such that the relationship of the sizes P1, P2, and D becomes P1 + P2 < D. The size of the space between the front side second flange 23u of the outer casing 23ea and the back side second flange 23x of the back side casing 23eb. Thereby, the size between the deodorizing filter 23a and the front side outer casing 23ea and the back side outer casing 23eb can be made within a predetermined interval dimension D.

Further, as described above, by making the second side 23ecc and the third side The respective side end portions of the 23ecd extend toward the outside of the heating portion housing portion 23ec to form a pair of front side first flanges 23t and a pair of front side second flanges 23u. In addition, each of the side end portions of the second side surface 23edc and the third side surface 23edd extends toward the outside of the heating portion housing portion 23ed, thereby forming a pair of back side first flanges 23w and a pair of back side second flanges 23x. Therefore, the heat generated by the PTC heater 23b is not easily diffused to the outside from the front side outer casing 23ea and the rear side outer casing 23eb. At this time, by forming each of the flanges to have a width dimension (for example, 20 mm) larger than the predetermined interval dimension D, it is possible to more effectively suppress heat generated by the PTC heater 23b from the front side casing 23ea and the back side casing 23eb. Spread to the outside.

Further, in the present embodiment described above, the size of the space between the deodorizing filter 23a and the front side heat radiating plate 23ca and the interval between the deodorizing filter 23a and the back side heat radiating plate 23cb are set to the same size. P3. However, the size of the gap between the deodorizing filter 23a and each of the heat radiating plates may be different. Further, the size of the space between the deodorizing filter 23a and the front side casing 23ea and the spacing between the deodorizing filter 23a and the back side casing 23eb are set to the same spacing dimension D. However, the size of the gap between the deodorizing filter 23a and each of the covers may be different.

Next, a member and a mounting method used when the assembled filter regeneration unit 23f and the deodorizing filter 23a are attached to the holding portion 23g will be described with reference to Fig. 6 . The holding portion 23g is formed in a substantially quadrangular shape using a synthetic resin material. A shape pair with the deodorizing filter 23a is provided at a central portion of the holding portion 23g. The opening portion 23gd. In addition, the regenerating portion accommodating portion 23ge is provided above the opening portion 23gd (the upper portion of the opening portion 23gd when the holding portion 23g is disposed in the ventilation passage 10). The regeneration portion accommodating portion 23ge is formed in a concave shape in accordance with the shape of the filter regeneration portion 23f.

The two first shafts 23ga are disposed at two corners of the lower portion of the holding portion 23g (below the holding portion 23g when the holding portion 23g is disposed in the ventilation passage 10, which will be described below). Each of the first shafts 23ga is inserted into the hole 23ma of the roller 23m. Thereby, the first shaft 23ga holds the roller 23m rotatably. The second shaft 23gb is disposed on the left side of the regeneration unit accommodating portion 23ge (the left side when the deodorizing filter 23a is viewed from the front side). The second shaft 23gb is inserted into the second gear 23k. Thereby, the second shaft 23gb holds the second gear 23k rotatably. The drive unit fixing portion 23gc is disposed on the right side of the regeneration unit housing portion 23ge (the right side when the deodorizing filter 23a is viewed from the front side), and holds the driving portion 23h.

The drive unit 23h is, for example, a stepping motor. A drive gear 23j formed of a synthetic resin material is attached to an output shaft of the drive portion 23h. The drive gear 23j is a gear that meshes with the first gear 23ac of the deodorizing filter 23a.

The second gear 23k is formed of a synthetic resin material, and meshes with the first gear 23ac of the deodorizing filter 23a like the driving gear 23j. The rotation detecting unit 23r is, for example, a light chopper. The optical chopper is a sensor having a light-emitting portion and a light-receiving portion that face each other, and the light-receiving portion detects that the object blocks light from the light-emitting portion to determine the presence or absence and/or position of the object. Rotation detecting unit 23r Whether or not the deodorizing filter 23a is rotated is detected by detecting the rotation of the second gear 23k.

The four pressing members 23z are formed of a substantially pentagonal plate material using a synthetic resin material. Each of the pressing members 23z has a shape that can be fitted into the holding portion 23g. The pressing member 23z presses the roller 23m attached to the holding portion 23g, the drive gear 23j, and the second gear 23k so that they are not easily separated from the holding portion 23g.

The two rollers 23m are formed of a synthetic resin material having a cylindrical portion 23mb, an upper flange 23mc, and a lower flange 23md. The tubular portion 23mb is provided with a hole 23ma. In the present embodiment, the roller 23m has the same shape as the roller 23n described in FIG. The dimension between the upper flange 23mc and the lower flange 23md of the roller 23m is also the same size S as the dimension S between the upper flange 23nc and the lower flange 23nd of the roller 23n. Therefore, the detailed description of the roller 23m is omitted.

The step of attaching the filter regeneration unit 23f and the deodorizing filter 23a to the holding portion 23g by the above-described members will be described. First, the two first shafts 23ga of the holding portion 23g are fitted to the holes 23ma of the roller 23m, respectively. Thereby, the two rollers 23m are attached to the holding portion 23g. Next, the rotation detecting portion 23r and the second gear 23k are sequentially attached to the second shaft 23gb of the holding portion 23g. Next, the drive gear 23j is attached to the output shaft of the drive unit 23h, and the drive unit 23h is fixed to the drive unit fixing unit 23gc of the holding unit 23g.

Next, the filter regeneration unit 23f and the deodorizing filter 23a are attached to the holding unit 23g. Specifically, the filter regeneration unit 23f is inserted and fixed to the regeneration unit storage unit 23ge of the holding unit 23g. Further, in order to embed the first gear 23ac between the upper flange 23mc and the lower flange 23md of the two rollers 23m, and to drive the gear 23j and the second gear 23k with the first gear 23ac of the deodorizing filter 23a The deodorizing filter 23a is attached to the holding portion 23g in a meshing manner. Thereby, the drive gear 23j is rotated by the drive unit 23h, and the deodorizing filter 23a guided by the second gear 23k and the two rollers 23m is stably rotated.

Finally, the four pressing members 23z are respectively fitted above the two rollers 23m and above the driving gear 23j and the second gear 23k. Thereby, the assembly of the deodorizing unit 23 is completed. As described above, the assembled deodorizing unit 23 is disposed in the ventilation passage 10 of the air cleaner 1 by fixing the holding portion 23g to the back side of the dust collecting unit 22 on the partition plate 16.

If the deodorizing unit 23 is disposed in the ventilation passage 10, the air that has flowed into the ventilation passage 10 from each of the air suction ports passes through the deodorizing filter 23a. At this time, the air that has flowed into the central portion of the holding portion 23g and the portion other than the opening 23gd corresponding to the shape of the deodorizing filter 23a is blocked by the holding portion 23g, and is introduced into the ventilating surface of the deodorizing filter 23a (except The portion of the odor filter 23a that is not covered by the filter regeneration portion 23f). Further, as shown in FIG. 5, FIG. 6, FIG. 8, and FIG. 9, the center hole 23ad of the deodorizing filter 23a is the front side cover portion 23s and the rear side outer casing 23eb of the front side outer casing 23ea. The back side cover portion 23v is covered. Therefore, the air that has flowed into the center hole 23ad of the deodorizing filter 23a is blocked by the front side cover portion 23s and the back side cover portion 23v, and is introduced into the ventilating surface of the deodorizing filter 23a. That is, the front side cover portion 23s and the back side cover portion 23v are arranged to prevent air from flowing in the center hole 23ad of the deodorizing filter 23a. That is, the deodorizing unit 23 having the above configuration effectively introduces the air that has flowed into the ventilation passage 10 and passed through the deodorizing unit 23 into the deodorizing filter 23a. As a result, the deodorizing unit 23 can deodorize the air more effectively.

In the air cleaner 1 having the above configuration, if the user operates the operation unit 15 to start the operation of the air cleaner 1, the blower 25 is driven, and the first electric dust collector 22a and the dust collecting unit 22 are started. The second electric dust collector 22b is energized. Further, the humidification filter 24a of the humidification unit 24 starts to rotate. When the blower 25 is driven, air is taken into the main body portion 11 from the upper suction port 13a, the right side suction port 13b, and the left side suction port 13c.

The air sucked into the inside of the main body portion 11 flows in the following manner.

(1) The lower portion of the deodorizing unit 23 in the ventilation passage 10 and the upper portion of the humidifying unit 24 are overlapped in the front-rear direction, and the air is prefilter 21 → dust collecting unit 22 → deodorizing unit 23 → humidifying unit 24 The order of the flow.

(2) The lower portion of the deodorizing unit 23 in the ventilation passage 10 and the upper portion of the humidifying unit 24 are not overlapped in the front-rear direction, and the air flows in the order of the prefilter 21 → the dust collecting unit 22 → the deodorizing unit 23, Or prefilter The flow of the device 21 → the dust collecting unit 22 → the humidifying unit 24 flows. Further, air is blown out from the upper air outlet 14a, the right side air outlet 14b, and the left side air outlet 14c to the room in which the air cleaner 1 is installed.

As described above, when the air passes through the ventilation passage 10 inside the air cleaner 1, the dust and pollen are removed by the prefilter 21 and the energized dust collecting unit 22. Then, the air passes through the ventilating surface of the deodorizing filter 23a via the opening 23gd of the holding portion 23g. The ventilating surface of the deodorizing filter 23a is a surface on which the deodorizing unit 23 is exposed from the filter regenerating portion 23f to the venting passage 10. When the air passes through the ventilating surface of the deodorizing filter 23a, the odor component of the air is removed. Further, the air is humidified as it passes through the humidifying unit 24. Further, as described above, the dust collecting unit 22 is disposed on the upstream side of the deodorizing unit 23. Therefore, the air that has flowed into the deodorizing unit 23 is air from which dust, pollen, or the like is removed. Therefore, the deodorizing filter 23a that blocks the deodorizing unit 23 due to dust, pollen, or the like is suppressed.

Further, when the air cleaner 1 is operated, the PTC heater 23b is continuously energized. Further, the drive unit 23h drives the deodorizing filter 23a to rotate at a predetermined angle (for example, 30 degrees) every predetermined time. Thereby, the deodorizing ability of the portion of the deodorizing filter 23a covered by the filter regeneration unit 23f is reproduced. In other words, during the operation of the air cleaner 1, the deodorizing ability of the portion of the deodorizing filter 23a covered by the filter regenerating portion 23f is regenerated, and the air is removed by the other portions of the deodorizing filter 23a. smelly. In addition, the predetermined time mentioned above is the deodorizing ability of the deodorizing filter 23a. The time required for birth, for example two hours.

As described above, the PTC heater 23b is attached to the front side heat sink 23ca. Further, the first joint surface 23cda of the first joint portion 23cd of the back side heat sink 23cb and the second joint surface 23cea of the second joint portion 23ce are joined to the filter facing surface 23caa of the front side heat sink 23ca. Therefore, the heat generated by the PTC heater 23b is efficiently conducted to the back side heat sink 23cb from the both end portions of the front side heat sink 23ca through the first joint portion 23cd and the second joint portion 23ce. In the filter regeneration unit 23f, the PTC heater 23b as a heating element can heat both the front side and the back side of the deodorizing filter 23a. Thereby, the deodorizing ability of both surfaces of the deodorizing filter 23a can be regenerated by the PTC heater 23b.

Further, a heat insulator 23d is disposed between the front side heat sink 23ca and the front side outer casing 23ea, and between the back side heat sink 23cb and the back side outer casing 23eb. Therefore, heat is not easily released from the front side heat dissipation plate 23ca and the back side heat dissipation plate 23cb heated by the PTC heater 23b to the outside of the filter regeneration portion 23f. As a result, the heat generated by the PTC heater 23b can be efficiently conducted to the deodorizing filter 23a.

Further, as described above, the interval between the front side surface of the deodorizing filter 23a and the front side first flange 23t of the front side casing 23ea, the back side surface of the deodorizing filter 23a and the back side of the back side casing 23eb.

In a manner, the dust collecting unit 22 and the blower 25 are disposed. In the vicinity of the center of the fan motor 25b, the flow of air generated by the rotation of the turbo fan 25a is small. Therefore, the flow of air is small in the space near the center of the fan motor 25b inside the main body portion 11. On the other hand, the space between the first electric dust collector 22a and the second electric dust collector 22b in the dust collecting unit 22 is small in the dust collecting ability of the passing air. Therefore, by making the height of the space coincide with the height of the center of the fan motor 25b, the first electric dust collector 22a and the second electric dust collector 22b can be disposed in a space in which the blades of the turbo fan 25a having a large flow of air are disposed. . Thereby, dust removal by the dust collection unit 22 can be performed efficiently.
