[Figure 7] FIG. 7 is a diagram showing a schematic cross section taken along the line CC in FIG. 6. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and description thereof will not be repeated.

[0010] An outline of a blower device 1 according to an embodiment will be described with reference to Fig. 1 to Fig. 3. Fig. 1 is a perspective view of the blower device 1 according to the embodiment, and shows a state in which a panel 5 and a filter 4 are removed from a housing 3. Fig. 2 is a perspective view of the blower device 1 according to the embodiment, and shows a cross section of the blower device 1. Fig. 3 shows a state in which the panel 5 is removed from the blower device 1 shown in Fig. 2. The blower device 1 is placed on the floor of a room, etc.

[0011] 1 and 2 generates air that passes through a filter 4, which will be described later. The air blower 1 is, for example, an air purifier, a dehumidifier, or a humidifier.

[0012] The air blower 1 includes an air blower section 2, a housing 3, a filter 4, and a panel 5.

[0013] The blower 2 generates wind. For example, the blower 2 is a centrifugal fan. Figures 1 and 2 show a sirocco fan, which is an example of a centrifugal fan. Note that the blower 2 may be a fan other than a turbo fan or a centrifugal fan.

[0014] The housing 3 is a box that houses the blower unit 2. The material of the housing 3 includes, for example, sheet metal or synthetic resin. However, the material of the housing 3 is not particularly limited. The housing 3 has a front wall 31, a rear wall 32, a pair of side walls 33, an air passage 34, an outlet 35, and an inlet 36. Note that only one of the pair of side walls 33 is shown in Figs. 1 and 2, and the other of the pair of side walls 33 is hidden.

[0015] The front wall 31 is oriented in a direction in which a user will primarily use the blower 1. The rear wall 32 is disposed opposite the front wall 31. The side wall 33 is positioned between the front wall 31 and the rear wall 32.

[0016] The ventilation passage is a passage provided inside the housing 3. The blower unit 2 is provided in the ventilation passage . The air F1 generated by the blower unit 2 passes through the ventilation passage .

[0017] The air outlet 35 is an opening through which the wind F1 passing through the ventilation passage 34 goes out to the outside of the housing 3. The air outlet 35 is formed in the front wall 31. Note that the air outlet 35 may be formed in a place other than the front wall 31.

[0018] The suction port 36 is an opening through which air outside the housing 3 is sucked into the ventilation passage 34. The suction port 36 is formed in the side wall 33. The suction port 36 includes a recessed portion 361 and an opening 363. The recessed portion 361 is a portion that is recessed toward the inside of the housing 3. The opening 363 is formed in a bottom surface 362 of the recessed portion 361. The air outside the housing 3 passes through the opening 363 and is sucked into the ventilation passage 34. The suction port 36 may be formed in the front wall 31 or the rear wall 32.

[0019] The filter 4 is disposed at the air inlet 36. The filter 4 removes dust, odor components, and other substances from the air.

[0020] 2 and 3, the panel 5 is detachably attached to the housing 3 so as to cover the suction port 36 from the exterior side of the housing 3. The panel 5 attached to the housing 3 covers the filter 4 arranged in the suction port 36. The panel 5 shown in FIGS. 2 and 3 is a plate of a size sufficient to cover the entire suction port 36.

[0021] The filter 4 has a first fitting portion on a part of a surface 4A facing the panel 5. On the other hand, the panel 5 has a second fitting portion on a part of a surface 5A facing the filter 4. The second fitting portion has a shape that fits with the first fitting portion.

[0022] For example, the first fitting portion has a shape that protrudes toward the second fitting portion, and the second fitting portion has a recessed shape. Alternatively, the first fitting portion may have a recessed shape, and the second fitting portion may have a shape that protrudes toward the first fitting portion.

[0023] The second fitting portion fits into the first fitting portion, thereby reducing the sum of the thicknesses of the panel 5 and the filter 4. This allows the air blower 1 to be made more compact.

[0024] The structures of the filter 4 and the panel 5 will be described with reference to Figs. 1 to 5. Fig. 4 is an enlarged cross-sectional view of part A in Fig. 2. Fig. 5 is an enlarged cross-sectional view of part B in Fig. 2. As will be described in detail later, in the filter 4 and the panel 5 shown in Figs. 1 to 5, the first fitting portion protrudes toward the second fitting portion, and the second fitting portion is recessed.

[0025] As shown in FIG. 1, the filter 4 has a collector 41 and a frame .

[0026] The collector 41 collects dust, odor components, and other substances. The collector 41 is, for example, a HEPA (High Efficiency Particulate Air) filter body 411, a deodorizing filter body 412, or a pre-filter body 413, as shown in Fig. 2. The HEPA filter body 411 is a filter made of nonwoven fabric formed into a paper-like material. The deodorizing filter body 412 is a filter that removes odor components. The pre-filter body 413 is a filter that collects dust larger in size than the dust collected by the HEPA filter.

[0027] Collector 41 includes HEPA filter body 411, deodorizing filter body 412, and pre-filter body 413 arranged in that order from the position closest to the inside of housing 3. The type and number of collectors 41, and the order in which they are arranged from the position closest to the inside of housing 3, are not particularly limited.

[0028] Frame 42 is a component integral with collector 41 located furthest from the inside of housing 3, specifically, pre-filter body 413. In addition, frame 42 is a component that fixes collector 41 other than collector 41 integral with frame 42, specifically, HEPA filter body 411 and deodorizing filter body 412, to housing 3. To fix HEPA filter body 411 and deodorizing filter body 412 to housing 3, first, bottom surface 362 of recess 361 of housing 3 and frame 42 sandwich HEPA filter body 411 and deodorizing filter body 412. With HEPA filter body 411 and deodorizing filter body 412 sandwiched between bottom surface 362 and frame body 42, frame body 42 is attached to housing 3, whereby HEPA filter body 411 and deodorizing filter body 412 are fixed to housing 3. Frame body 42 has outer edge portion 421 and protrusion 422, as shown in FIG.

[0029] The outer edge portion 421 is a portion that is attached to the side wall 33. The shape of the outer edge portion 421 is frame-like. The inner space of the outer edge portion 421 has a size approximately equal to that of the recessed portion 361. The wind F1 generated by the blower 2 passes through the inner space of the outer edge portion 421 and reaches the collector 41.

[0030] The protrusions 422 are portions that hold the collector 41. In Fig. 3, as an example, a plurality of columnar protrusions 422 are provided at intervals vertically running along the inside of the outer edge portion 421. In detail, the plurality of protrusions 422 are arranged in a lattice pattern. The protrusions 422 illustrated in Fig. 3 hold the main body 413 of the prefilter as described above.

[0031] When the panel 5 is attached to the housing 3, the protrusion 422 protrudes toward the panel 5. That is, the first fitting portion is the protrusion 422 that protrudes toward the panel 5 attached to the housing 3. Note that the protrusion 422 may have any shape or structure as long as it protrudes toward the panel 5 attached to the housing 3.

[0032] The panel 5 has a recess 51, a connection portion 53, and an opening 54.

[0033] 4, the recess 51 is a recessed portion into which the protrusion 422 of the filter 4 fits when the panel 5 covers the filter 4. That is, the second fitting portion is the recess 51 into which the protrusion 422 fits. Specifically, the recess 51 is a groove provided on the surface 5A of the panel 5 facing the filter 4. When the collector 41 is fixed to the housing 3, the panel 5 is attached to the housing 3, so that the protrusion 422 fits into the recess 51.

[0034] If the first fitting portion is the protrusion 422 and the second fitting portion is the recess 51, there is no need to provide a recess in the filter 4. This simplifies the structure of the filter 4. Furthermore, the filter 4 with a simple structure can be made smaller. The smaller filter 4 reduces the space required to install the blower 1. Note that the recess 51 may have a portion into which the protrusion 422 does not fit.

[0035] The panel 5 further has a plurality of shielding portions 52. The plurality of shielding portions 52 face the filter 4 when the panel 5 is attached to the housing 3. The shielding portions 52 prevent the user's fingers or large foreign objects from entering the suction port 36.

[0036] The connection portion 53 connects two adjacent shielding portions 52, 52 among the multiple shielding portions 52. Preferably, the connection portion 53 also has a recess 51 provided on a surface 5A facing the filter 4 when attached to the housing 3, as shown in FIG. 5. In this way, when the panel 5 is attached to the housing 3, the protrusion 422 fits into the recess 51 provided in the connection portion 53. By fitting the protrusion 422 into the recess 51 provided in the connection portion 53, the sum of the thicknesses of the panel 5 and the filter 4 is reduced. Therefore, the air blower 1 can be made more compact.

[0037] The opening 54 is formed between two adjacent shielding portions 52, 52 among the multiple shielding portions 52. The opening 54 communicates with the air inlet 36 when the panel 5 is attached to the housing 3. The air F1 (see FIG. 2) generated by the blower 1 passes through the opening 54 and is sucked into the ventilation passage 34 from the air inlet 36.

[0038] The structure of the multiple shielding portions 52 will be described in detail with reference to Fig. 4. The multiple shielding portions 52 have an inner surface 521 and an outer surface 522, as shown in Fig. 4.

[0039] Inner surface 521 faces filter 4 when panel 5 is attached to housing 3. Inner surface 521 is provided with recess 51. By providing recess 51 on inner surface 521, shielding portion 52 and protrusion 422 overlap when panel 5 is attached to housing 3. Therefore, recess 51 is provided in collector 41 without reducing the area of ​​the portion through which air passes. As a result, blower device 1 can be made smaller without reducing the amount of air passing through collector 41.

[0040] When the panel 5 is attached to the housing 3, the outer surface 522 is located on the opposite side to the filter 4. The outer surface 522 is located farther from the filter 4 than the connection portion 53. Therefore, when the panel 5 is attached to the housing 3, the connection portion 53 is located on the inner side of the housing 3 than the outer surface 522. This makes it easier to make the panel 5 smaller. As a result, the blower device 1 can be made more compact.

[0041] A preferred structure of the multiple shielding portions 52 will be described with reference to Fig. 1 to Fig. 7. Fig. 6 is a front view of the blower 1 according to the embodiment, showing the blower 1 installed in contact with a wall W. Fig. 7 is a schematic view of the CC cross section of Fig. 6.

[0042] The multiple shielding portions 52 are arranged along a first direction D1 as shown in Figs. 1 to 6, and constitute a part of an end portion 55 of the panel 5 in a second direction D2 intersecting the first direction D1 (see Figs. 1 to 3 and Fig. 6). The shielding portions 52 illustrated in Figs. 1 to 5 are columnar portions. The first direction D1 is the width direction of the panel 5. The second direction D2 is the direction of gravity. The longitudinal direction of the shielding portions 52 is along the second direction D2. However, the longitudinal direction of the shielding portions 52 does not need to be strictly along the second direction D2, and may be inclined with respect to the second direction D2 as long as there is an opening 54 between two adjacent shielding portions 52, 52.

[0043] Specifically, the columnar shielding portion 52 has a shape that reaches the end portion 55 of the panel 5. The shape that reaches the end portion 55 of the panel 5 includes a shape in which the end portion 55 of the panel 5 and the end portion of the shielding portion 52 coincide with each other, and a shape in which the end portion of the shielding portion 52 goes in and out of the end portion 55 of the panel 5.

[0044] If a part of the end 55 of the panel 5 is composed of a plurality of shielding parts 52, as shown in Figs. 6 and 7, the air around the housing 3 is sucked into the air inlet 36 even when the blower 1 is installed so that the panel 5 abuts against the wall W of the room. Specifically, the wind F1 generated by the blower unit 2 passes from the space around the blower 1 through the space between the adjacent shielding parts 52 and passes through the air inlet 36. Therefore, the blower 1 does not need to be installed at a position distant from the wall W in order to suck in the air around the housing 3 through the air inlet 36. As a result, the space required for installing the blower 1 can be reduced.

[0045] Preferably, as shown in Figures 1 to 5, the multiple shielding parts 52 and the connecting parts 53 are arranged in a lattice pattern. In this way, the connecting parts 53 can effectively suppress deformation of the shielding parts 52. In addition, even if the blower device 1 is installed so that the panel 5 abuts against the wall W, the spaces provided between the multiple shielding parts 52 allow a sufficient amount of air to pass through. As a result, the blower device 1 can save the space required for installation without reducing the amount of air it draws in.

[0046] The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the above embodiments, and can be implemented in various forms without departing from the spirit of the present invention. The drawings are mainly schematic illustrations of each component for ease of understanding, and the thickness, length, number, spacing, etc. of each component shown in the drawings are different from the actual ones due to the convenience of drawing. In addition, the material, shape, dimensions, etc. of each component shown in the above embodiments are merely examples and are not particularly limited, and various modifications are possible within a range that does not substantially deviate from the configuration of the present invention.
