The deflector (3) has a vane (301) which receives the air current, and a shaft portion (302) which is located at a position different from the vane (301) and supports the vane (301) so as to be rotatable with respect to the blowout port (14).

Description

Technical Field

[0001] This disclosure relates to an air supply device with an air guide plate. Background Technology

[0002] As a related technology, an air supply device is known that includes a front guide plate and a rear guide plate as air direction adjustment plates for adjusting the air direction from the outlet (for example, refer to International Publication No. 2025 / 141023). In this air supply device, both the front and rear guide plates are provided with an axis in the middle (the middle part in the length direction) and rotate about an axis that is substantially parallel to the blowing surface of the outlet. Summary of the Invention

[0003] In the aforementioned related technologies, since the front air guide plate and the rear air guide plate rotate around an axis located in the middle of the length direction, a portion of the front air guide plate and the rear air guide plate will enter the main body of the device during the rotation process.

[0004] Therefore, in the above-mentioned related technologies, there is the following problem: in order to avoid interference between the front guide plate and part of the rear guide plate entering the main body of the device and other components inside the main body of the device, it is necessary to arrange other components in a position far away from the air outlet, which leads to the large size of the main body of the device.

[0005] In view of the above problems, the purpose of this disclosure is to provide an air supply device that does not easily lead to an increase in the size of the main body of the device.

[0006] One aspect of this disclosure relates to an air supply device including an air guide plate that controls the direction of airflow blowing out from the device body via an outlet. The air guide plate has: blades that receive the airflow; and a shaft located at a different position from the blades and supporting the blades so as to be rotatable relative to the outlet.

[0007] One aspect of this disclosure relates to an air supply device comprising an air guide plate that controls the direction of airflow blowing out from the device body via an outlet. The air guide plate has: blades that receive the airflow; and a shaft that supports the blades so that they are rotatable relative to the outlet. The blades are entirely located outside the outlet at any position within their movable range.

[0008] Invention Effects According to this disclosure, it is possible to provide an air supply device that does not easily lead to an increase in the size of the main body of the device. Attached Figure Description

[0037] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. The following embodiments are merely examples of the present disclosure and are not intended to limit the technical scope of the present disclosure.

[0038] In addition, the section lines of the cross-section are basically omitted in the sectional view in the attached figure.

[0039] [1] Composition of dehumidification device First, use Figures 1-4 The overall configuration of the dehumidification device 1 according to this embodiment will be described.

[0040] In this embodiment, for ease of explanation, the vertical direction in which the dehumidifier 1 can be used is defined as the up-down direction D1. Furthermore, based on the direction from which the dehumidifier 1 is viewed from the front, the left-right direction D2 is defined, and the front-back direction D3 is defined with the front side of the dehumidifier 1 as the front and the back side as the rear. However, these definitions are not intended to limit the direction of use of the dehumidifier 1 (the direction during use).

[0041] The dehumidifier 1 is used, for example, on a surface such as the top of a table or the floor of a room in a house. The dehumidifier 1 can stand upright on the surface when placed there. In other words, the dehumidifier 1 according to this embodiment is a self-standing and portable device, allowing the user to freely move it and place it at any location on the surface. Furthermore, although in Figures 1-4 Not shown in the figure, but multiple casters 18 can be installed on the bottom surface of the dehumidifier 1 (e.g., see reference). Figure 26 This allows the dehumidifier 1 to move on the mounting surface.

[0042] like Figure 1 and Figure 2 As shown, the dehumidifier 1 includes a device body 10 and a drain tank 2 that is detachably mounted on the device body 10. In other words, the dehumidifier 1 includes a drain tank 2 and a device body 10 on which the drain tank 2 is mounted. The detailed configuration of the drain tank 2 will be explained in “[2] Configuration of the drain tank”.

[0043] The main body 10 of the device includes a housing 11, an operation section 12, a filter section 13, a dehumidification section, and an air supply section. The dehumidification section and the air supply section are not shown in the figures.

[0044] In this embodiment, as an example, the housing 11 has a generally rectangular parallelepiped shape (quadrangular prism shape) with a length in the vertical direction D1. Furthermore, the housing 11 can take various shapes, including, for example, a polygonal prism or a cylinder, in addition to a rectangular parallelepiped shape. The housing 11 has a bottom panel 111, a top panel 112, a front panel 113, a rear panel 114, a left side panel 115, and a right side panel 116. In this embodiment, unless otherwise stated, all components of the housing 11 are made of resin.

[0045] Bottom panel 111 is a panel-shaped component forming the bottom surface of housing 11. Top panel 112 is a panel-shaped component forming the top surface of housing 11. Front panel 113 is a panel-shaped component forming the front surface of housing 11. Rear panel 114 is a panel-shaped component forming the rear surface of housing 11. Left side panel 115 is a panel-shaped component forming the left side of housing 11, and appears quadrilateral in top view. Right side panel 116 is a panel-shaped component forming the right side of housing 11. All these panels appear quadrilateral in top view.

[0046] An operation section 12 is formed on the upper surface of the top panel 112. In this embodiment, as an example, the operation section 12 is formed at the front end of the upper surface of the top panel 112. The operation section 12 includes a plurality of buttons that can be pressed by the user. The operation section 12 can handle operations such as starting and stopping the operation of the dehumidifier 1, switching the airflow of the dehumidifier 1 to "weak", "medium", "strong" and "automatic", and timer operations.

[0047] An air outlet 14 for blowing air is provided from the rear end of the top panel 112 to the upper end of the rear panel 114. An air guide plate 3 for controlling the direction of the airflow blown from the air outlet 14 is provided at the air outlet 14. The detailed structure of the air guide plate 3 will be explained in "[3] Structure of the air guide plate".

[0048] In other words, in the dehumidifier 1 according to this embodiment, the operation section 12 is disposed on the front side of the top panel 112, and the air outlet 14 is disposed on the rear side of the top panel 112. Therefore, in the dehumidifier 1 according to this embodiment, for example, when using the airflow blown from the air outlet 14 to dry laundry, the user operating the operation section 12 facing the dehumidifier 1 will not be exposed to the airflow blown from the air outlet 14, which has the advantage of minimizing user discomfort.

[0049] The front panel 113 is configured to be detachable relative to the housing 11. Figure 3 This indicates the dehumidifier 1 after removing the front panel 113. For example... Figure 3 As shown, a filter section 13 is provided at the front of the interior of the housing 11, and an air intake 15 for drawing in air is provided at the rear of the filter section 13. The air intake 15 is composed of multiple opening groups, which are formed by the intersection of multiple grid strips extending in the vertical direction D1 and multiple grid strips extending in the horizontal direction D2. The front panel 113 is mounted on the housing 11 with a gap that allows air to be drawn in toward the air intake 15.

[0050] The filter unit 13 includes filters such as a dust collection filter or a deodorizing filter to process the air drawn in from the intake port 15. The dust collection filter can capture dust, pollen, smoke, and fine particulate matter (such as PM2.5) contained in the air. The deodorizing filter can remove odors from the air. In this embodiment, the filter unit 13 has a pre-filter 131 that can capture larger debris in the air and a HEPA (High Efficiency Particulate Air) filter 132 that can capture airborne microparticles. In addition, in this embodiment, the filter unit 13 also has a filter element 133 disposed in the air intake path of a dust sensor (not shown) that detects the degree of air pollution.

[0051] Below the filter section 13 of the housing 11, a recess is formed that is recessed inward (rearward) towards the inside of the housing 11. This recess constitutes a receiving section 16 capable of accommodating an air supply device accessory 4 (hereinafter referred to as "accessory 4" unless otherwise stated) that can be mounted on the device body 10. In this embodiment, the receiving section 16 is configured to accommodate accessory 4, hose 5, and nozzle 6 in a disassembled form (see reference). Figure 21 Specifically, the housing 16 is configured such that a nozzle 6, which is an accessory component of attachment 4, is housed at the rear bottom of the housing 16, and attachment 4 and a hose 5, which is an accessory component of attachment 4, are housed in front of the nozzle 6. The detailed configuration of attachment 4 will be explained in “[4] Configuration of Attachment”.

[0052] An air passage (not shown) for airflow is formed inside the housing 11. The air passage is configured to connect the inlet 15 and the outlet 14, and a dehumidification section and an air supply section are arranged sequentially from the inlet 15 to the outlet 14.

[0053] The dehumidification unit dehumidifies the air passing through the air duct. In this embodiment, the dehumidification unit is a compressor type, including an evaporator and a condenser. The evaporator and condenser are connected to the compressor and expansion valve to form a refrigeration cycle. In the dehumidification unit, the air in the air duct is cooled by the evaporator. As a result, the moisture in the air is removed by condensation. The moisture generated by condensation on the evaporator (condensate) drips downwards due to its own weight and is stored in the drain tank 2 located below the dehumidification unit inside the housing 11.

[0054] Furthermore, in this embodiment, the dehumidification unit is a compressor type, but it is not limited to this. For example, the dehumidification unit can be a desiccant type, or it can be a combination of a compressor type and a desiccant type.

[0055] The air supply unit directs air from the intake 15 toward the outlet 14. In this embodiment, the air supply unit is a multi-bladed centrifugal fan. However, the air supply unit is not limited to a multi-bladed centrifugal fan, as long as it includes a mechanism capable of directing air from the intake 15 to the outlet 14.

[0056] like Figure 4 As shown, a rectangular opening 116a is provided on the right side panel 116 when viewed from above. Furthermore, a space 17 for accommodating the drain tank 2 is formed on the housing 11 from this opening 116a toward the inside of the housing 11. When the drain tank 2 is housed within the space 17, the opening 116a is covered by one side of the drain tank 2 (the decorative panel 24 described later). This side of the drain tank 2 covering the opening 116a is approximately flush with the surface of the right side panel 116 and is decorated with the same pattern or decoration as the right side panel 116. Therefore, when the drain tank 2 is housed within the device body 10, the design of the housing 11 is not easily compromised by the drain tank 2.

[0057] When the drain tank 2 is housed inside the main body 10 of the device, it stores the condensate generated by the dehumidification unit. Here, since the drain tank 2 can only store a limited amount of condensate, the user needs to remove the drain tank 2 from the main body 10 and perform the operation of draining the condensate stored in the drain tank 2 before the condensate stored in the drain tank 2 reaches the upper limit of the capacity of the drain tank 2 (hereinafter referred to as "drainage operation").

[0058] In this embodiment, to facilitate the user's removal of the drain tank 2 from the device body 10, the drain tank 2 is configured as follows. That is, as shown... Figure 4 As shown, with the drain tank 2 housed within the device body 10, at least a portion of the grip portion 231 of the handle 23 held by the user when moving the drain tank 2 is exposed. Therefore, the user can easily grip the grip portion 231 and pull the drain tank 2 out of the device body 10 in the left-right direction D2. Furthermore, in the up-down direction D1, a gap is provided between the grip portion 231 and the upper end of the exposed surface of the drain tank 2 (decorative panel 24) for the user to insert their hand. Therefore, the user can insert their hand into this gap and grip the grip portion 231, making it easy to grip the grip portion 231, and consequently, easy to pull the drain tank 2 out of the device body 10.

[0059] Furthermore, in this embodiment, the dehumidifier 1 is configured to remove the drain tank 2 from the main body 10 by pulling it out to the right, but it is not limited to this. For example, the dehumidifier 1 may be configured to allow the drain tank 2 to be pulled out from the main body 10 to the left, front, or rear.

[0060] [2] Composition of the drainage tank The following mainly uses Figure 5 The detailed configuration of the drain tank 2 according to this embodiment will now be described. The drain tank 2 is detachably mounted on the device body 10. When housed within the device body 10, it receives and stores condensed water generated and dripping from the dehumidification unit. Furthermore, when the drain tank 2 is removed from the device body 10, it can switch between a storage posture for storing water (here, condensed water; unless otherwise stated, this will be referred to as "condensed water") within the tank body 21 and for transporting it, and a drainage posture for draining the condensed water from the tank body 21.

[0061] Figure 6 This is a diagram showing the attitude change of the drainage tank 2 according to this embodiment. Figure 6 The upper left section indicates the containment posture. Figure 6 The upper right section indicates the carrying posture. Figure 6 The lower section indicates the drainage posture. The containment posture refers to the posture in which the drain tank 2 can be contained within the main body 10 of the device. In other words, the drain tank 2 is contained within the space 17 of the housing 11 in a containment posture. The handling posture refers to the posture of the drain tank 2 when the user holds the grip portion 231 (described later) of the handle 23 (described later) provided on the drain tank 2 to move the drain tank 2. The drainage posture refers to the posture of the drain tank 2 when, in a location where condensation can be drained from the drain tank 2, the user tilts the drain tank 2 to drain the condensation inside the main body 21 to the outside through the drain outlet 20 (described later).

[0062] like Figure 5 As shown, the drainage tank 2 includes a tank body 21, a tank cover 22, a handle 23, a decorative panel 24, and a drainage cover 25.

[0063] The main body 21 is a container body with an opening 210 on its upper surface, which stores condensate water generated by the dehumidification section located above the main body 21. A lid 22 and a drain cover 25 are provided at the opening 210 of the main body 21 to cover the opening 210. Furthermore, when the drain tank 2 is housed within the main body 10, condensate water dripping onto the lid 22 flows into the main body 21 through the water inlet 223 (described later) on the lid 22, thereby being stored in the main body 21.

[0064] The main body 21 of the box has a bottom wall 211 (see reference). Figure 7The front wall 212, rear wall 213, right wall 214, and left wall 215 constitute the outer shell of the main body 21. Furthermore, the portion enclosed by the upper ends of each of the front wall 212, rear wall 213, right wall 214, and left wall 215 constitutes an opening 210. In this embodiment, the portion of the opening 210 opposite to the drain cover 25 constitutes a drain outlet 20, which is used to drain condensate from the main body 21 to the outside when the drain tank 2 is detached from the main body 10. In other words, the drain outlet 20 is an opening for draining condensate from the main body 21 when the drain tank 2 is in the draining position.

[0065] like Figure 7 As shown, the box body 21 has a narrow portion 21a and a wide portion 21b that is wider than the narrow portion 21a in the front-rear direction D3.

[0066] The narrow portion 21a is the part that protrudes to the left from the front end of the left wall 215 of the main body 21, and is rectangular in shape when viewed from above. With the drain tank 2 housed within the main body 10, the central portion of the left wall 215 of the main body 21 in the front-rear direction D3 is, according to the shape of the compressor located to the left of the drain tank 2, concave to the right (i.e., inside the main body 21) when viewed from above. Furthermore, the narrow portion 21a is not limited to being located at the front end of the left wall 215 of the main body 21; it can be provided as long as it protrudes to the left from any part of the left wall 215.

[0067] The narrow section 21a is located on the left wall 215 of the main body 21 and extends from the center of the vertical direction D1 to the upper end. In this embodiment, the narrow section 21a is provided with a detection unit (not shown) for detecting whether the water level of condensation inside the main body 21 is full. The detection unit is, for example, a Hall effect IC, which detects that the condensation is full when a float installed inside the main body 21 and capable of moving up and down according to the water level reaches a predetermined water level.

[0068] The wide portion 21b is the part of the box body 21 other than the narrow portion 21a, and is the main part of the box body 21. For example, the wide portion 21b is rectangular when viewed from above.

[0069] Furthermore, in this embodiment, the box body 21 has a narrow portion 21a and a wide portion 21b, but it may also lack the narrow portion 21a. In this case, the box body 21 is composed only of the wide portion 21b.

[0070] like Figure 5As shown, on the inner surface of the front wall 212 of the box body 21, a protruding wall 216 protruding toward the rear (i.e., the inner side of the box body 21) is provided at the center in the left-right direction D2. Similarly, on the inner surface of the rear wall 213 of the box body 21, a protruding wall 216 is formed at the center in the left-right direction D2, protruding toward the front (i.e., the inner side of the box body 21).

[0071] Each protrusion 216 is configured to extend from the upper end of the front wall 212 (or the rear wall 213) to its lower end, and its interior is hollow. A bearing portion 216a is provided at the upper end of each protrusion 216, and a pair of shaft portions 234 (described later) of the handle 23 are respectively inserted into this bearing portion 216a. Furthermore, in Figure 5 Only one of the pair of bearing portions 216a is shown in the figure. By inserting the pair of shaft portions 234 of the handle 23 into the pair of bearing portions 216a, the handle 23 can be rotatably supported on the box body 21 with the pair of shaft portions 234 as the central axis.

[0072] The cover 22 is a flat plate that matches the shape of the opening 210 of the main body 21, except for the left end, and is detachably mounted relative to the main body 21. The cover 22 has a pair of bearing portions 221, a conical surface 222, a water inlet 223, and a through hole 224.

[0073] A pair of bearing portions 221 are positioned at a predetermined distance in the front-rear direction D3 at the left end of the cover 22. This predetermined distance is equal to the length of the shaft portion 254 (described later) of the drain cover 25 in the front-rear direction D3. A pair of protrusions 254a (described later) provided on the shaft portion 254 of the drain cover 25 are inserted into each of the bearing portions 221. Thus, the drain cover 25 can be rotatably supported on the cover 22 about the shaft portion 254 as its central axis.

[0074] The conical surface 222 is positioned on the cover 22 below the dehumidification section when the drain tank 2 is housed within the main body 10 of the device. In this embodiment, the conical surface 222 is located at the left end of the cover 22, to the right of the pair of bearing portions 221. The conical surface 222 gradually slopes downward from the center of the cover 22 in the front-rear direction D3 toward the front end. Furthermore, a gap is provided between the front end of the conical surface 222 and the cover 22, which forms a water inlet 223 for allowing condensed water to flow into the main body 21 of the device. The condensed water flowing through the water inlet 223 flows downward along the inner surface of the front wall 212 of the main body 21 of the device.

[0075] Furthermore, in this embodiment, the cover 22 is provided with only one set of conical surfaces 222 and water inlets 223, but multiple sets may also be provided. For example, a set of conical surfaces and inlets may also be provided, wherein the conical surfaces gradually slope downward from the central part in the front-rear direction D3 of the cover 22 toward the rear end, and the inlets are the gap between the rear end of the conical surfaces and the cover 22.

[0076] The through hole 224 has a length in the front-rear direction D3 and is rectangular in shape when viewed from above. It is a hole that passes through the center of the lid 22 in the front-rear direction D3. The through hole 224 is sized to allow a portion of the handle 23 (specifically the grip portion 231 and the pair of first arms 232 described later) to pass through.

[0077] The drain cover 25 is a component mounted on the cover 22 and is configured to cover the drain outlet 20 in a first position (see reference). Figure 8 ) and open the second position of drain outlet 20 (refer to Figure 9 The drain cover 25 has a first component 251, a second component 252, a third component 253, and a shaft portion 254. In this embodiment, the first component 251, the second component 252, the third component 253, and the shaft portion 254 are integrally formed.

[0078] The first component 251 is rectangular in shape when viewed from above and has a length in the front-rear direction D3. The center of the left end of the first component 251 matches the shape of the left wall 215 of the box body 21 and is recessed to the right (i.e., the inside of the box body 21) when viewed from above. At both ends of the left end of the first component 251 in the front-rear direction D3, there are upwardly protruding protrusions 251a. Each protrusion 251a is sized such that, with the drain cover 25 in the first position, its top end is located above the upper end of the left wall 215 of the box body 21. Each protrusion 251a is sized such that, with the drain box 2 housed within the device body 10, it is located near the space 17 (refer to) where the drain box 2 is housed. Figure 4 The top of the protrusion 254a. Here, "close to" includes the case where the protrusion 254a is in contact with the top, or the distance between the protrusion 254a and the top is less than a threshold (e.g., a few millimeters to a dozen millimeters).

[0079] The shaft portion 254 is located at the center of the right end of the first component 251 and is a cylindrical component with a length in the front-rear direction D3. At both ends of the shaft portion 254 in the front-rear direction D3, there are outwardly protruding cylindrical protrusions 254a. These protrusions 254a are respectively inserted into a pair of bearing portions 221 of the cover 22.

[0080] The second component 252 is rectangular in shape when viewed from above, and its length in the front-to-back direction D3 is shorter than that of the first component 251 and the third component 253. The second component 252 is the component that connects the center of the right end of the first component 251 and the center of the left end of the third component 253. With the drain cover 25 installed on the box cover 22, the second component 252 is located below the box cover 22.

[0081] The third component 253 is rectangular in shape when viewed from above. Its length in the front-rear direction D3 is shorter than that of the first component 251 and longer than that of the second component 252. At both ends of the left end of the third component 253, there are protrusions 253a protruding outwards in the front-rear direction D3. At the center of the right end of each protrusion 253a, there is a recess 253b that curves to the left. When the drain cover 25 is in the first position and the drain tank 2 is in a transport posture, the claw portion 232a (described later) of the handle 23 is inserted into each recess 253b.

[0082] The drain cover 25 is configured to rotate about the shaft 254 when mounted on the lid 22. Therefore, when the first component 251 on the left side of the shaft 254 moves upward, the second component 252 and the third component 253 on the right side of the shaft 254 move downward. Conversely, when the first component 251 moves downward, the second component 252 and the third component 253 move upward. Furthermore, when the drain cover 25 (first component 251) is in a first position that covers the drain outlet 20 of the main body 21, the third component 253 covers the through hole 224 of the lid 22. Conversely, when the drain cover 25 (first component 251) is in a second position that opens the drain outlet 20, the third component 253 opens the through hole 224 of the lid 22.

[0083] Furthermore, the drain cover 25 is configured to move from a first position to a second position as the drain tank 2 changes from a handling posture to a draining posture. Specifically, when the drain tank 2 is in the draining posture, the drain cover 25 is not restricted by a part of the handle 23 from rotating clockwise when looking forward (movement from the first position to the second position), nor is it restricted by a part of the cover 22 from rotating clockwise when looking forward (movement from the first position to the second position). Thus, since there are no parts restricting the movement of the drain cover 25, when the drain tank 2 changes from a handling posture to a draining posture, the drain cover 25 can rotate about the shaft portion 254 as the axis of rotation from the first position to the second position.

[0084] Decorative panel 24 is a panel with the same pattern or decoration as the right side panel 116 of housing 11. Decorative panel 24 is configured to be detachable from the outside of the right wall 214 of the main body 21. When the drain tank 2 is housed within the main body 10, decorative panel 24 is flush with the right side panel 116 of housing 11.

[0085] The handle 23 has a gripping portion 231 for the user to hold when carrying the drain tank 2, and is mounted on the tank body 21 in a manner in which the position of the gripping portion 231 in the vertical direction D1 is variable. Furthermore, the gripping portion 231 only needs to be able to move at least in the vertical direction D1, and for example, it can also move further in directions intersecting the vertical direction D1 (left-right direction D2 or front-back direction D3). The handle 23 has a gripping portion 231, a pair of first arms 232, a pair of second arms 233, a pair of shaft portions 234, and a restraining portion 235.

[0086] The grip portion 231 is a rod-shaped member having a length in the front-rear direction D3. The grip portion 231 is capable of displacement in the vertical direction D1 on the outside of the box body 21, more specifically above the box body 21.

[0087] A pair of first arms 232 are connected to their respective ends in the front-rear direction D3 of the grip portion 231, and are rod-shaped components extending in a parallel manner in a direction orthogonal to the length direction of the grip portion 231. At the lower end of each first arm 232, a cylindrical shaft portion 234 protruding outward in the front-rear direction D3 is provided. Of the pair of shaft portions 234, the front shaft portion 234 is supported on the bearing portion 216a of the front protrusion 216 of the case body 21, and the rear shaft portion 234 is supported on the bearing portion 216a of the rear protrusion 216 of the case body 21. Thus, the handle 23 can be rotatably supported on the case body 21 about the pair of shaft portions 234 as rotation axes.

[0088] Furthermore, each of the first arms 232 has a claw portion 232a protruding to the left at its lower end. When the drain cover 25 is in the first position and the drain tank 2 is in a transport posture, each claw portion 232a is inserted into the recess 253b of the third component 253 of the drain cover 25.

[0089] A pair of second arms 233 are connected to the lower ends of a pair of first arms 232, and are rod-shaped components extending in a direction approximately parallel to the length direction of the first arms 232. At the upper end of each second arm 233, a limiting plate 233a is provided that protrudes outward in the front-rear direction D3 and is rectangular in shape when viewed from above. Each limiting plate 233a is configured to rotate with the handle 23, and a portion of the corresponding protrusion 216 is located on its track.

[0090] Furthermore, when the handle 23 is rotated counterclockwise as viewed from the front and the grip portion 231 reaches its upper limit position (described later), the lower ends of each limiting piece 233a will contact the corresponding protrusion 216, thereby limiting the rotation of the handle 23 (see reference). Figure 10In other words, each limiting piece 233a acts as a first limiting part that contacts the box body 21 when the grip 231 is in its upper limit position, thus limiting the movement of the handle 23. Furthermore, when the handle 23 is rotated clockwise from the front and the grip 231 reaches its lower limit position (described later), the upper end of each limiting piece 233a contacts the corresponding protrusion 216, thereby limiting the rotation of the handle 23 (see reference). Figure 11 In other words, each limiting piece 233a corresponds to a second limiting part that contacts the box body 21 and restricts the movement of the handle 23 when the grip portion 231 is in the lower limit position. Thus, in this embodiment, each limiting piece 233a simultaneously functions as both a first limiting part and a second limiting part.

[0091] The suppressing part 235 is a component with a length in the front-rear direction D3 and a rectangular shape when viewed from above. Both ends of the suppressing part 235 are connected to the lower ends of a pair of second arms 233. The center of the left end of the suppressing part 235 matches the shape of the left wall 215 of the box body 21, and is recessed to the right (i.e., inside the box body 21) when viewed from above. When the gripping part 231 is in the lower limit position, the suppressing part 235 is close to the left wall 215 of the box body 21 (see reference). Figure 11 When the gripping part 231 is in the upper limit position, the restraining part 235 approaches the bottom wall 211 of the box body 21 (see reference). Figure 10 Here, "close" includes the situation where the inhibition part 235 is in contact with the left wall 215 or the bottom wall 211, or the distance between the inhibition part 235 and the left wall 215 or the bottom wall 211 is less than a threshold (e.g., a few millimeters to a dozen millimeters).

[0092] The following describes the range of motion of the grip portion 231 of the handle 23. The grip portion 231 is configured to move between an upper limit position and a lower limit position. Here, as... Figure 10 As shown, the upper limit position refers to the position where the grip portion 231 reaches its highest height in the vertical direction D1 when the handle 23 is rotated. Specifically, the upper limit position refers to the end position of the grip portion 231 when the handle 23 is rotated counterclockwise while looking forward. When the grip portion 231 is in the upper limit position, it is located above the rotation center (a pair of shaft portions 234) of the handle 23. In this embodiment, the user holds the grip portion 231 in the upper limit position to move the drain tank, therefore, the grip portion 231 being in the upper limit position is equivalent to the drain tank 2 being in a moving posture.

[0093] like Figure 11As shown, the lower limit position refers to the position where the grip portion 231 reaches its lowest height in the vertical direction D1 when the handle 23 is rotated. Specifically, the lower limit position refers to the end position of the grip portion 231 when the handle 23 is rotated clockwise while looking forward. When the grip portion 231 is in the lower limit position, it is located above the right wall 214 of the main body 21. In this embodiment, with the grip portion 231 in the lower limit position, the drain tank 2 is housed within the main body 10 of the device; therefore, the grip portion 231 being in the lower limit position is equivalent to the drain tank 2 being in a housed position.

[0094] In addition, in this embodiment, when the grip 231 is in a position lower than the upper limit position, the drain cover 25 (first component 251) can be opened and closed freely, and the condensed water in the main body 21 can be drained to the outside. Therefore, when the grip 231 is in a position lower than the upper limit position, it is equivalent to the drain box 2 being in a draining posture.

[0095] The features of the drainage tank 2 according to this embodiment will be described below.

[0096] In the drain boxes shown in the related art, opening and closing the lid requires effort during drainage operations. In contrast, in the drain box 2 of this embodiment, the drain cover 25 is configured to move from a first position to a second position as the drain box 2 changes from a transport posture to a drainage posture. Therefore, the user only needs to tilt the drain box 2, and the drain cover 25 will be pushed by the condensate inside the box body 21, thereby opening the drain outlet 20 and allowing the condensate to drain. Therefore, the drain box 2 of this embodiment does not require effort to open and close the lid during drainage operations, unlike the drain boxes shown in the related art, and has the advantage of easily draining condensate. Furthermore, when the drain box 2 is in the drainage posture, it can also be designed so that it can be opened without being pushed by the condensate inside the box body 21, for example, by tilting the box body 21 at a predetermined angle or more.

[0097] Furthermore, when the device body 10 is moved while the drain tank 2 is installed on the device body 10, the condensed water inside the tank body 21 sloshes, causing the condensed water to sometimes leak from the drain outlet 20. Similarly, when the drain tank 2 is removed from the device body 10, the condensed water inside the tank body 21 sloshes, causing the condensed water to sometimes leak from the drain outlet 20.

[0098] In contrast, in the drain tank 2 of this embodiment, when the drain tank 2 is in a position other than the draining position, the drain cover 25 is in the first position of covering the drain outlet 20. Therefore, even if the condensed water in the tank body 21 shakes, the condensed water will be pushed back into the tank body 21 by the drain cover 25, which has the advantage that the condensed water is not easy to leak out of the drain outlet 20.

[0099] Furthermore, the drainage tank 2 according to this embodiment, by including the various configurations shown below, has various advantages such as preventing condensation from easily overflowing from the tank body 21 to the outside. The specific configurations will be described below.

[0100] In this embodiment, such as Figure 12 As shown, at least the end of the drain cover 25 on the side of the drain outlet 20 (here, the left end) is configured such that, when the drain outlet 20 is covered, it is located below the upper end of the wall on the side of the drain outlet 20 of the box body 21 (here, the left wall 215). In other words, when the drain cover 25 is in the first position, at least the end (left end) on the side opposite to the direction in which the drain box 2 is pulled out from the device body 10 is located below the upper end of the box body 21.

[0101] Therefore, even if condensation adheres to the drain cover 25 during drainage operations, the condensation is unlikely to overflow the wall of the tank body 21, thus minimizing the risk of leakage after drainage. Furthermore, when returning the drain tank 2 to the device body 10 after drainage, the likelihood of the drain cover 25 moving above the upper part of the wall of the tank body 21 is reduced, making it less likely to become stuck on the device body 10 and facilitating easy return of the drain tank 2 to the device body 10.

[0102] Furthermore, when the drain tank 2 is pulled out of the device body 10, due to inertia, the condensed water inside the tank body 21 will rise along the wall of the tank body 21. Without taking any measures, the drain cover 25, which can be opened and closed freely, may be pushed by the condensed water, causing the condensed water to overflow to the outside of the tank body 21. Therefore, in this embodiment, as Figure 12 As shown, the drain cover 25 has an inclined portion 255 that gradually slopes downward as it extends in the direction opposite to the pull-out direction of the drain box 2 (here, to the left). Therefore, the inclined portion 255 can suppress condensation that rises along the wall of the box body 21 due to inertia, and has the advantage that condensation is less likely to overflow to the outside of the box body 21.

[0103] Specifically, such as Figure 13 As shown in the left-hand figure, without the inclined portion 255 provided on the drain cover 25, condensed water subjected to inertial force may move upward along the wall of the tank body 21 and push the drain cover 25, thereby overflowing to the outside of the tank body 21. Furthermore, in Figure 13 In the diagram, the hollow arrow indicates the direction in which the drain tank 2 is pulled out. Conversely, in this embodiment, as... Figure 13As shown in the figure on the right, since the drain cover 25 is provided with an inclined part 255, the condensed water will be guided along the inclined part 255 to the inside of the box body 21. Therefore, the drain cover 25 is not easily pushed upward by the condensed water, and the condensed water is not easily overflowed to the outside of the box body 21.

[0104] Furthermore, in this embodiment, the lid 22 also has an inclined portion 225 at the right end (see reference). Figure 5 The inclined portion 225 gradually slopes downward as it extends toward the pull-out direction (here, to the right) of the drain tank 2. Therefore, even if the condensed water moves upward along the wall of the tank body 21 opposite to the drain outlet 20 (here, the right wall), the condensed water will be guided along the inclined portion 225 to the inside of the tank body 21, so that the condensed water is less likely to overflow to the outside of the tank body 21 through the gap between the tank cover 22 and the tank body 21.

[0105] Furthermore, in this embodiment, as Figure 12 As shown, the main body 21 has a stepped portion 217 protruding to the side opposite to the pull-out direction (here, the left wall 215) on at least the inner wall opposite to the pull-out direction. Furthermore, when the drain cover 25 is in the first position (i.e., in the position where the drain outlet 20 is covered), its end opposite to the pull-out direction (here, the left end) is opposite to the upper surface of the stepped portion 217. Specifically, when the drain cover 25 is in the first position, its left end rests on the upper surface of the stepped portion 217.

[0106] Therefore, even assuming that the condensed water attempts to push the drain cover 25 upward, the step portion 217 can reduce the impact force of the condensed water, and has the advantage that the condensed water is less likely to overflow to the outside of the box body 21. In particular, in this embodiment, the upper end of the wall on the side of the drain outlet 20 of the box body 21 (here, the left wall) is located above the step portion 217, so the condensed water reaching the step portion 217 is difficult to cross this wall, and thus the condensed water is less likely to overflow to the outside of the box body 21.

[0107] Furthermore, in this embodiment, the step 217 gradually slopes towards the inside (right side) of the main body 21 as it extends from top to bottom. Therefore, condensation reaching the step 217 is guided along this slope to the inside of the main body 21, which has the advantage that condensation is less likely to remain on the step 217.

[0108] In addition, in this embodiment, such as Figure 12 As shown, at the aforementioned end (here, the left end) of the drain cover 25, a rib 256 is provided that protrudes from the lower surface in the direction opposite to the pull-out direction (here, to the left). The rib 256 is a flat plate-shaped portion with a length in the front-rear direction D3 on the lower surface of the left end of the drain cover 25.

[0109] Therefore, compared to the case where the drain cover 25 does not have ribs 256, the aforementioned end of the drain cover 25 can be strengthened, making it less likely for gaps to form between the drain cover 25 and the main body 21, thus preventing condensation from easily overflowing from the main body 21 to the outside. Here, if the ribs 256 are configured to protrude from the upper surface of the drain cover 25, condensation may easily remain at the corner formed by the ribs 256 and the upper surface of the drain cover 25. In contrast, in this embodiment, since the ribs 256 are configured to protrude from the lower surface of the drain cover 25, the aforementioned corner is absent, thus preventing condensation from easily remaining.

[0110] Furthermore, when there is a large amount of condensed water stored inside the tank body 21, the condensed water stored inside the tank body 21 will fluctuate during the process of pulling the drain tank 2 out of the device body 10. This may push the drain cover 25, which can be opened and closed freely, causing the condensed water to sometimes overflow to the outside of the tank body 21. Therefore, in this embodiment, as... Figure 5 As shown, when the drain cover 25 is in the first position (i.e., in the position where the drain outlet 20 is covered), it has a protrusion 251a that protrudes upward from its upper surface to the upper end of the tank body 21. Therefore, when the drain tank 2 is pulled out from the device body 10, the protrusion 254a near the top of the space 17 that houses the drain tank 2 restricts the upward movement of the drain cover 25, making it difficult to open the drain cover 25, improving the sealing performance, and providing the advantage that condensate is less likely to leak from the tank body 21.

[0111] Furthermore, when the drain tank 2 is moved to a location where condensate can be drained, the drain tank 2 may shake, causing the condensate stored inside the tank body 21 to sometimes leak out. Especially when the drain cover 25 can open and close freely as described above, the shaking of the drain tank 2 will cause fluctuations in the condensate stored inside the tank body 21, which may push the drain cover 25 open, resulting in leakage. Therefore, in this embodiment, the drain tank 2 also includes a locking mechanism 26, which restricts the movement of the drain cover 25 from the first position, at least when the drain tank 2 is in a transporting posture. In this embodiment, as... Figure 5 As shown, the locking mechanism 26 consists of a pair of claws 232a provided on the handle 23 and a pair of recesses 253b provided on the third component 253 of the drain cover 25. In other words, the locking mechanism 26 is provided on the handle 23. Furthermore, in this embodiment, the locking mechanism 26 restricts the movement of the drain cover 25 from the first position by engaging the claws 232a provided on the handle 23 with the recesses 253b provided on the drain cover 25. Therefore, in the drain tank 2 according to this embodiment, the drain cover 25 is not easily opened when the drain tank 2 is moved, the sealing performance is improved, and it has the advantage of not easily leaking.

[0112] Furthermore, in this embodiment, the locking mechanism 26 is configured to be in either a locked state, restricting the movement of the drain cover 25 from a first position, or an unlocked state, depending on the position of the handle 23. Specifically, when the grip portion 231 of the handle 23 is in the upper limit position, the locking mechanism 26 engages with the recesses 253b on the drain cover 25 to achieve the locked state. When the grip portion 231 is in a position lower than the upper limit position, the locking mechanism 26 disengages from the recesses 253b on the drain cover 25 to achieve the unlocked state.

[0113] Therefore, in this embodiment, since the locking mechanism 26 can be switched to either the locked state or the unlocked state by the user's natural actions such as gripping the handle 23's grip portion 231 and lifting the drain tank 2, the user does not need to directly operate the locking mechanism 26, which has the advantage of easily improving the ease of use of the drain tank 2.

[0114] Furthermore, in this embodiment, when the drainage tank 2 is in a transport posture (refer to...), Figure 6 (upper right section), when the user tilts the drain tank 2, the grip portion 231 of the handle 23 will rotate clockwise from the upper limit position to the position viewed from the front as the drain tank 2 tilts (refer to the upper right section). Figure 6 (The lower section). In other words, when the drain tank 2 is in the draining position, the grip 231 will move downward. Therefore, in this embodiment, the user only needs to tilt the drain tank 2 to make it in the draining position, and the handle 23 will rotate, thereby switching the locking mechanism 26 from the locked state to the unlocked state. Therefore, the user can perform the draining operation without operating the handle 23, which has the advantage of easily improving the ease of use of the drain tank 2.

[0115] Furthermore, as mentioned earlier, when the drain tank 2 is pulled out of the device body 10, due to inertia, the condensed water inside the tank body 21 will rise along the wall of the tank body 21. Without taking any measures, the drain cover 25, which can be opened and closed freely, may be pushed by the condensed water, causing the condensed water to sometimes overflow to the outside of the tank body 21. Especially in this embodiment, since the wall on the drain outlet 20 side of the tank body 21 is narrower in the front-rear direction D3 than the other walls, the condensed water is very likely to overflow to the outside of the tank body 21 without taking any measures.

[0116] Therefore, in this embodiment, as Figure 11 As shown, the handle 23 has a gripping portion 231 on the outside of the case body 21, based on a rotation axis (here, a pair of shaft portions 234) relative to the case body 21, and a restraining portion 235 on the inside of the case body 21. Furthermore, as... Figure 5 As shown, the suppression part 235 has a longer surface in the direction along the rotation axis (here, the front-to-back direction D3). Therefore, when the drain box 2 is pulled out from the device body 10, the suppression part 235 on the wall (here, the left wall 215) near the drain outlet 20 side of the box body 21 acts as a breakwater, and can suppress condensation water that rises along the wall of the box body 21 due to inertia by the suppression part 235, thus having the advantage that condensation water is less likely to overflow to the outside of the box body 21.

[0117] Furthermore, in this embodiment, when the tank body 21 is tilted to drain the condensate inside the tank body 21, the suppression part 235 approaches the wall (here, the left wall 215) on the side of the drain outlet 20 of the tank body 21. Therefore, since the flow momentum of the condensate can be suppressed by the suppression part 235, it has the advantage of easily adjusting the drainage volume of the condensate per unit time. This advantage is particularly effective when the size of the drain outlet 20 is large.

[0118] Furthermore, in this embodiment, the handle 23 has a limiting piece 233a (first limiting part). When the gripping part 231 is in the upper limit position (i.e., in the carrying posture), the limiting piece 233a contacts the box body 21 and restricts the movement of the handle 23. Therefore, in the carrying posture, the movement of the handle 23 is restricted by the limiting piece 233a (here, counterclockwise rotation when viewed forward), that is, the handle 23 is fixed. Therefore, when carrying the drain box 2, the condensate inside the box body 21 is not easily shaken, and it has the advantage that the condensate is not easily overflowed to the outside of the box body 21.

[0119] In particular, in this embodiment, the limiting piece 233a (first limiting part) is not provided on the shaft portion 234 of the handle 23, but on the second arm 233. This is because if the limiting piece 233a is provided on the shaft portion 234 of the handle 23, since it is close to the rotation center of the handle 23, the angle at which the limiting piece 233a restricts the rotation of the handle 23 is prone to deviation, and since the limiting piece 233a is prone to contact with the box body 21, it is prone to wear.

[0120] Furthermore, in this embodiment, as described above, a restraining part 235 is provided on the handle 23. When the gripping part 231 is in its upper limit position, the restraining part 235 is fixed at a position near the bottom wall 211 of the main body 21. Therefore, the restraining part 235 acts as resistance to condensation within the main body 21, effectively reducing the shaking of the handle 23. Additionally, since the restraining part 235 also reduces the shaking of condensation within the main body 21, it also makes it less likely for condensation to overflow to the outside of the main body 21.

[0121] Furthermore, in this embodiment, the handle 23 has a limiting piece 233a (second limiting part). When the grip part 231 is in the lower limit position (i.e., in the storage posture), the limiting piece 233a contacts the box body 21 and restricts the movement of the handle 23. Therefore, in the storage posture, the movement of the handle 23 is restricted by the limiting piece 233a (clockwise rotation when viewed forward), that is, the handle 23 is fixed. Thus, it has the advantage that the handle 23 can be positioned when the drain box 2 is stored in the device body 10, and the user can easily grasp the grip part 231 of the handle 23 when pulling the drain box 2 out of the device body 10.

[0122] Furthermore, in this embodiment, the limiting piece 233a is configured to simultaneously function as both the first limiting part and the second limiting part, but it is not limited to this. For example, the limiting piece for the first limiting part and the limiting piece for the second limiting part can be provided separately.

[0123] Furthermore, in this embodiment, a pair of shaft portions 234 of the handle 23 are mounted on the inner wall of the box body 21 (i.e., the handle 23 is supported inside the box body 21), and the box cover 22 has a through hole 224 through which the grip portion 231 of the handle 23 and a pair of first arms 232 (i.e., a part of the handle 23) pass. With the grip portion 231 of the handle 23 and the pair of first arms 232 (i.e., a part of the handle 23) passing through the through hole 224, the box cover 22 is mounted on the box body 21 in a manner that covers the opening of the box body 21. Therefore, for example, when cleaning the inside of the box body 21, the box cover 22 can be removed from the box body 21 simply by moving the box cover 22 upwards without removing the handle 23, thus providing the advantage of easy cleaning of the inside of the box body 21.

[0124] Furthermore, in this embodiment, the drain cover 25 (third component 253) is configured such that, in the first position (i.e., in the position where the drain outlet 20 is covered), the through hole 224 is covered; and in the second position (i.e., in the position where the drain outlet 20 is open), the through hole 224 is open. Therefore, except when performing drainage operations and removing the cover 22 from the box body 21, in the normal state, the through hole 224 is covered by the drain cover 25, thus having the advantage that condensate is less likely to overflow to the outside of the box body 21 through the through hole 224.

[0125] Furthermore, in this embodiment, a conical surface 222 is provided at the dripping point of condensed water from the dehumidification section on the lid 22. The conical surface 222 gradually slopes downward as it extends toward the side wall (front wall 212) of the main body 21, and has a water inlet 223 penetrating the lid 22 at its front end (see reference). Figure 5Therefore, the condensed water dripping from the dehumidifier onto the lid 22 flows along the conical surface 222 to the water inlet 223, and then flows along the side wall of the main body 21 to the bottom wall 211 through the water inlet 223. This has the advantage of easily suppressing the impact noise generated when condensed water drips onto the bottom wall 211 or the water surface. Furthermore, the water inlet 223 can be configured such that the first arm 232 is located directly below the front end of the conical surface 222. Thus, even if the amount of condensed water dripping from the dehumidifier onto the lid 22 is small, and the condensed water does not reach the side wall of the main body 21 but drips downwards from the front end of the conical surface 222, the condensed water will still drip onto the first arm 232 and flow down along it. Therefore, even if the amount of condensed water is small, it has the advantage of easily suppressing the impact noise generated when condensed water drips onto the bottom wall 211 or the water surface.

[0126] [3] Composition of the air guide plate The following uses Figures 14-19 The detailed configuration of the air guide plate 3 according to this embodiment will be described. The air guide plate 3 is a component that controls the direction of the airflow sent from the air supply section inside the device body 10 to the outside through the air outlet 14, and is provided on the air supply device. In this embodiment, the air supply device is equivalent to the dehumidification device 1.

[0127] like Figure 14 As shown, the air guide plate 3 is disposed on the rear side of the operation section 12 on the top panel 112 of the main body 10 of the device. Specifically, on the rear side of the operation section 12 on the top panel 112, as shown... Figure 15 As shown, a frame 19, which appears rectangular when viewed from above, is provided. An air outlet 14, also rectangular when viewed from above, is provided on the frame 19. The air guide plate 3 is mounted on this frame 19 and is positioned at the rear of the operating unit 12. The air guide plate 3 includes multiple (here, two) air guide plate bodies 30, multiple (here, two) auxiliary air guide plates 31, and a housing 32. Hereinafter, when it is necessary to distinguish between the two air guide plate bodies 30, the air guide plate body 30 located at the rear will be referred to as "first air guide plate body 30a," and the air guide plate body 30 located at the front will be referred to as "second air guide plate body 30b."

[0128] Each air guide plate 30 is a component that controls the direction (mainly the front-to-back direction D3) of the airflow blown out from the main body 10 of the device through the outlet 14. In this embodiment, multiple air guide plates 30 (first air guide plate 30a and second air guide plate 30b) are arranged in a direction orthogonal to the axial direction (left-right direction D2) of the shaft portion 302 of the air guide plate 30, and more specifically, in a direction orthogonal to both the axial and vertical directions D1 (front-to-back direction D3). Therefore, compared to using a single air guide plate 30 to control the direction of the airflow, it has the advantage of easier and more precise control of the airflow direction. Figure 16 and Figure 17 As shown, each air guide plate 30 has a blade 301, a pair of shafts 302 and a pair of arms 303.

[0129] The blade 301, viewed from above, is rectangular and has a length in the left-right direction D2. The blade 301 is configured to receive airflow. Specifically, the blade 301 controls the airflow along its surface by receiving the airflow from the air supply section within the main body 10 on its lower surface (back side). Figure 14 As shown, the upper surface (surface) of blade 301 is entirely decorated with a pattern or decoration. Alternatively, the upper surface of blade 301 may not be decorated with a pattern or decoration.

[0130] like Figure 15 As shown, a plurality of ribs 301a are provided on the lower surface (back side) of the blade 301. Each rib 301a protrudes from the lower surface of the blade 301 in a direction orthogonal to the lower surface and is integrally formed with the blade 301 to connect the leading edge and trailing edge of the blade 301. The plurality of ribs 301a are arranged at predetermined intervals along the longitudinal direction (left-right direction D2) of the blade 301. In addition, the plurality of ribs 301a are inclined such that the angle between the longitudinal direction and the front-rear direction D3 gradually increases as they move outward from the center portion of the longitudinal direction of the blade 301. In other words, the plurality of ribs 301a are arranged radially on the back side of the blade 301. In other words, the blade 301 has ribs 301a that protrude from the surface (back side) receiving the airflow, and whose longitudinal direction is inclined relative to the direction orthogonal to the axial direction (left-right direction D2) of the shaft portion, more specifically, relative to the direction orthogonal to both the axial direction and the vertical direction D1 (front-rear direction D3). Therefore, each air guide plate 30 can not only control the direction of airflow in the front-to-back direction D3, but also has the advantage of easily controlling the direction of airflow in the left-to-right direction D2 through each rib 301a. Furthermore, since the back of each air guide plate 30 is reinforced by each rib, it has the advantage of easily improving the durability of each air guide plate 30.

[0131] In this embodiment, viewed from above, the length of the blade 301 in the left-right direction D2 is longer than the length of the outlet 14 in the left-right direction D2. In other words, the blade 301 is sized such that, when in the closed position (described later), it can shield the outlet 14 in the left-right direction D2, preventing it from being exposed. In other words, the dimension of the blade 301 in the axial direction (left-right direction D2) of the shaft portion 302 is larger than that of the outlet 14. Therefore, airflow is less likely to leak from both ends of the outlet 14 in the left-right direction D2, providing the advantage of easily suppressing accidental airflow leakage.

[0132] Furthermore, in this embodiment, the blades 301 of the first air guide plate 30a and the blades 301 of the second air guide plate 30b are configured with different sizes. Specifically, as shown... Figure 14 As shown, the length of the first guide vane 30a in the front-rear direction D3 is longer than the length of the second guide vane 30b in the front-rear direction D3. In other words, the blades 301 of the plurality of guide vanes 30 have different dimensions at least in the direction orthogonal to the axial direction (left-right direction D2) of the shaft, and more specifically, in the direction orthogonal to both the axial and vertical directions D1 (front-rear direction D3). Therefore, compared to the case where the blades 301 of the plurality of guide vanes 30 have the same dimension in the front-rear direction D3, it has the advantage of easier control of the airflow direction. For example, when the blades 301 of each guide vane 30 are in the fully open position, if the blades 301 of each guide vane 30 have the same dimension in the front-rear direction D3, the airflow may not be able to reach the blades 301 of the first guide vane 30a, making it difficult to control the airflow direction. In contrast, in this embodiment, when the blades 301 of each guide vane 30 are in the fully open position, the airflow easily reaches the blades 301 of the first guide vane 30a, making it easier to control the airflow direction.

[0133] A pair of shaft portions 302 are respectively mounted at both ends along the length direction (left-right direction D2) of the frame 19. The pair of shaft portions 302 are connected to the blade 301 via a pair of arms 303. Specifically, of the pair of shaft portions 302, the left shaft portion 302 is connected to the left end of the rear end edge of the blade 301 via the left arm 303 of the pair of arms 303, and the right shaft portion 302 is connected to the right end of the rear end edge of the blade 301 via the right arm 303. Thus, the blade 301 can rotate about the pair of shaft portions 302 as a central axis. Here, each arm 303 of the second guide vane 30b is approximately U-shaped when viewed from the left-right direction D2, and is curved to prevent interference with the operating part 12 when the blade 301 rotates.

[0134] In this embodiment, the blades 301 of each air guide plate 30 are configured to rotate between a closed position and a fully open position about a pair of shaft portions 302 as a central axis. Here, as Figure 16 As shown, the closed position refers to the position where the blade 301 rotates counterclockwise about a pair of shafts 302 as the central axis, so that the upper surface (surface) of the blade 301 is approximately flush with the top panel 112 of the device body 10, and the blade 301 partially covers the blowhole 14. Furthermore, as... Figure 17 As shown, the fully open position means that the blade 301 rotates clockwise around the pair of shafts 302 as the central axis when viewed from the left, so that the blade 301 reaches the foremost position within its movable range.

[0135] Furthermore, when the blades 301 of the first guide vane 30a are in the closed position, they cover the rear half of the outlet 14 when viewed from above. Similarly, when the blades 301 of the second guide vane 30b are in the closed position, they cover the front half of the outlet 14 when viewed from above. In other words, when the blades 301 of the first and second guide vanes 30a and 30b are in the closed position, they cover the entire outlet 14 when viewed from above. In other words, the blades 301 of each of the plurality of guide vanes 30 (here, the first and second guide vanes 30a) can be moved to a closed position that covers a portion of the outlet 14. Furthermore, the blades 301 of the plurality of guide vanes 30 cover the outlet 14 when in the closed position. Therefore, airflow is less likely to leak from the outlet 14 by bypassing the blades 301 of each guide vane 30, thus easily suppressing accidental airflow leakage.

[0136] Furthermore, when the blades 301 of each air guide plate 30 are in the closed position, the blades 301 of each air guide plate 30 cover the entire air outlet 14 when viewed from above, but this does not mean that the air outlet 14 is completely closed. That is, in this embodiment, as... Figure 16 As shown, the upper end of the frame 19 gradually slopes downward from the front end to the rear end. Therefore, even when the blades 301 of each air guide plate 30 are in the closed position, there is a gap 14a between the rear end of the first air guide plate 30a and the upper end of the rear end of the frame 19, through which airflow can be delivered to the outside of the device body 10.

[0137] Here, in this embodiment, as Figure 16 and Figure 17 As shown, a pair of shaft portions 302 are located at a different position from the blade 301. Specifically, viewed from the vertical direction D1, the shaft portions 302 are located outside the blade 301 without overlapping it, and more specifically, in front of the tip of the blade 301. In other words, each shaft portion 302 is located outside the blade 301 and rotatably supports the blade 301 relative to the outlet 14. Therefore, in this embodiment, the blade 301 is approximately flush with the top panel 112 in the closed position, and in all positions except the closed position, including the fully open position, it is located above the top panel 112, not below it, and further, not inside the outlet 14. In other words, the blade 301 is entirely located outside the outlet 14 at any position within its movable range.

[0138] Each auxiliary air guide plate 31 is positioned further inside the device body 10 than the outlet 14, and is used to control the direction (mainly the left-right direction D2) of the airflow blown out from inside the device body 10 through the outlet 14. In this embodiment, the two auxiliary air guide plates 31 are separated by a partition blade 191 (see reference) located at the center of the frame 19 in the longitudinal direction (left-right direction D2). Figure 15 The enclosure is divided into two parts, which are arranged in a manner along the length direction (left-right direction D2) of the enclosure 32 and housed within the enclosure 32 (see reference). Figure 18 Each auxiliary air guide plate 31 has multiple (three in this case) first blades 311 and second blades 312.

[0139] Each first blade 311 is rectangular in shape when viewed from above, and is configured to receive airflow. Specifically, each first blade 311 receives airflow from the air supply section inside the device body 10 on at least one of its left and right sides, thereby controlling the airflow direction along the surface of each first blade 311. In other words, the plurality of first blades 311 respectively control the direction of airflow in the axial direction (left-right direction D2) of the shaft portion 302 of the air guide plate body 30. At both ends of each first blade 311 in the front-rear direction D3, a first shaft portion 311a is provided. Furthermore, each first blade 311 is rotatably supported on the housing 32 with the first shaft portion 311a as the central axis by inserting the front first shaft portion 311a into the bearing portion 322 (described later) provided on the front wall of the housing 32, and the rear first shaft portion 311a into the bearing portion 322 provided on the rear wall of the housing 32. In this embodiment, in each auxiliary air guide plate 31, a plurality of first blades 311 are supported on the housing 32 at predetermined intervals along the length direction (left-right direction D2) of the housing 32.

[0140] In this embodiment, each first blade 311 is configured to change its angle by being moved by the user's hand. Alternatively, each first blade 311 may also be configured to change its angle electrically, for example, using an actuator.

[0141] At the center of each first blade 311 in the front-rear direction D3, there is a cutout 311b extending from the lower edge to near the upper edge and having a length in the vertical direction D1. The shape of the cutout 311b matches the shape of the second blade 312 as viewed from the left-right direction D2, and its size is set to allow the second blade 312 to be inserted.

[0142] The second blade 312 is rectangular in shape when viewed from above and has a length in the left-right direction D2. In this embodiment, the second blade 312 is sized such that its length in the left-right direction D2 is longer than the length between two first blades 311 located at both ends when a plurality of first blades 311 are arranged at a predetermined interval. At the lower edge of the second blade 312, a plurality of bearing portions 312a spaced at predetermined intervals in the left-right direction D2 are provided. A second shaft portion 311c (described later) of a corresponding first blade 311 is inserted into each bearing portion 312a.

[0143] Here, at the lower edge of each first blade 311, a second shaft portion 311c is provided, which connects to the open end of the lower end of the cutout 311b. Furthermore, each first blade 311 is connected to the second blade 312 by inserting the second shaft portion 311c into a bearing portion 312a provided on the second blade 312. Therefore, when any one of the multiple first blades 311 moves, the other first blades 311 connected to the second blade 312 will also move accordingly. Specifically, with... Figure 19 The positions of the first blades 311 shown in the middle section are used as reference positions. For example, when any one of the first blades 311 rotates counterclockwise, such as... Figure 19 As shown in the previous paragraph, the other first blades 311 will also rotate counterclockwise. Furthermore, at the reference position, for example, when any one of the first blades 311 rotates clockwise, as... Figure 19 As shown in the lower section, the other first blades 311 also rotate clockwise. In this way, the second blade 312 is connected to the plurality of first blades 311, and is configured to support the plurality of first blades 311 moving together.

[0144] And, as Figure 16 As shown, the second blade 312 tilts forward from the center of the vertical direction D1 towards the upper end. Therefore, the second blade 312 receives the airflow from the air supply section within the device body 10 on its tilted front surface, thereby controlling the airflow along the tilted surface of the second blade 312. In other words, the second blade 312 controls the airflow in a direction orthogonal to the axial direction (left-right direction D2) of the shaft portion 302 of the air guide plate 30, and more specifically, in a direction orthogonal to both the axial direction and the vertical direction D1 (front-back direction D3). Thus, the second blade 312 not only functions to link multiple first blades 311 together, but also controls the direction of the airflow in the front-back direction D3. Therefore, in the dehumidification device 1 (air supply device) according to this embodiment, compared to the case where the airflow direction in the front-back direction D3 is controlled solely by the air guide plate 30, it has the advantage of being easier to control the airflow direction in the front-back direction D3 more precisely.

[0145] Furthermore, in this embodiment, the tilt angle of the second blade 312 is the same as the tilt angle of the blade 301 when each air guide plate 30 is in the fully open position. Of course, the tilt angle of the second blade 312 is not limited to this; for example, it can also be the same as the tilt angle of the blade 301 when each air guide plate 30 is in the semi-open position.

[0146] The housing 32 is a cuboid component with an open upper surface, and it houses a plurality of auxiliary air guide plates 31. In this embodiment, the housing 32 houses a plurality of (two in this case) auxiliary air guide plates 31 arranged in a longitudinal direction (left-right direction D2). The housing 32 is mounted on the frame 19 by appropriate mounting means such as screws, and is thus positioned below the plurality of air guide plate bodies 30 and the air outlet 14.

[0147] like Figure 18 As shown, multiple rectangular vent holes 321 are provided on the bottom wall of the housing 32 when viewed from above. These vent holes 321 are arranged in a grid pattern. The airflow from the air supply unit flows through these multiple vent holes 321 to each auxiliary air guide plate 31. The airflow passing through each auxiliary air guide plate 31 flows through the blow-out port 14 to each air guide plate body 30.

[0148] On the upper edge of the front wall of the housing 32, a plurality of bearing portions 322 (here, 6) spaced at predetermined intervals in the left-right direction D2 are provided. Similarly, on the upper edge of the rear wall of the housing 32, a plurality of bearing portions 322 (here, 6) spaced at predetermined intervals in the left-right direction D2 are provided. Furthermore, the three bearing portions 322 located on the left side of the front wall and the three bearing portions 322 located on the left side of the rear wall are used to mount the left-side auxiliary air guide plate 31. In addition, the three bearing portions 322 located on the right side of the front wall and the three bearing portions 322 located on the right side of the rear wall are used to mount the right-side auxiliary air guide plate 31.

[0149] The features of the air guide plate 3 according to this embodiment will be described below.

[0150] In the air supply device A1 shown in the related technology, such as Figure 20 As shown, the air guide plate A2 is configured such that blades A21 rotate around a shaft portion A22 located in the middle of blades A21. Therefore, in the air supply device A1 shown in the related art, when blades A21 rotate around shaft portion A22, a portion of blades A21 enters the device body A3. To avoid interference between this portion of blades A21 and other components (here, the auxiliary air guide plate) within the device body A3, these other components need to be positioned separately from the outlet A4 in the vertical direction D1. Consequently, in the air supply device A1 shown in the related art, the size of the device body A3 in the vertical direction D1 increases, resulting in a larger device body A3.

[0151] Furthermore, in the air supply device A1 shown in the related technology, when an auxiliary air guide plate is included as another component, it is necessary to install the auxiliary air guide plate at a position that is relatively far from the outlet A4 in the vertical direction D1. Therefore, in the air supply device A1 shown in the related technology, a portion of the airflow controlled by the auxiliary air guide plate in the horizontal direction D2 collides with the inner wall of the device body A3 before reaching the outlet A4. Thus, in the air supply device A1 shown in the related technology, there is a problem that the airflow direction in the horizontal direction D2 cannot be sufficiently controlled, resulting in a narrowing of the airflow direction in the horizontal direction D2.

[0152] In contrast, in the air supply device (dehumidifier 1) according to this embodiment, in each air guide plate 30, each shaft portion 302 is located at a different position from the blade 301, configured to rotatably support the blade 301 relative to the outlet 14. In other words, in each air guide plate 30, the blade 301 is configured such that, at any position within its movable range, it is entirely located outside the outlet 14. Therefore, in the air supply device according to this embodiment, as... Figure 16 and Figure 17 As shown, when the blades 301 rotate around each shaft 302, the blades 301 do not enter the device body 10. Therefore, the blades 301 do not interfere with other components (here, the auxiliary air guide plate 31) within the device body 10. Thus, in the air supply device according to this embodiment, it is not necessary to separate other components from the outlet 14 in the vertical direction D1. Therefore, the size of the air supply device in the vertical direction D1 can be reduced, which has the advantage of not easily leading to an enlarged device body A3.

[0153] Furthermore, in the air supply device according to this embodiment, compared with the air supply device A1 shown in the related art, the auxiliary air guide plate 31 can be installed near the outlet 14. Therefore, the airflow controlled by the auxiliary air guide plate 31 in the left-right direction D2 is less likely to collide with the inner wall of the device body 10 and easily reaches the outlet 14. Therefore, the air supply device according to this embodiment has the advantages of easily controlling the direction of the airflow in the left-right direction D2 and easily expanding the airflow direction in the left-right direction D2.

[0154] [4] Composition of the appendix The following uses Figure 21 and Figure 22 The detailed configuration of Annex 4 involved in this embodiment will be described. Annex 4, for example, is used in the making of shoe 7 (refer to...) Figure 23When objects such as wardrobes or other items are dry, the device body 10 of the dehumidifier 1 (air supply device) is installed to guide airflow from the device body 10 to the object. More specifically, the accessory 4 is detachably installed on the device body 10 of the dehumidifier 1, which blows airflow from the outlet 14, and is a component for guiding airflow to an external outlet 8 located at a different position than the outlet 14 and different from the device body 10.

[0155] In this embodiment, a hose 5 (described later) is detachably mounted on Annex 4. This hose 5 is a component with an external air outlet 8. Furthermore, a nozzle 6 (described later) is detachably mounted on the hose 5. This nozzle 6 is also a component with an external air outlet 8. Annex 4 is used to dry objects by appropriately mounting the hose 5 or the nozzle 6 according to the type of object. Annex 4 includes a mounting part 41 and an air collection part 42.

[0156] The mounting part 41 is a portion installed on the main body 10 of the dehumidifier 1 at a position corresponding to the outlet 14. In this embodiment, the mounting part 41 includes an upper wall 411 that is rectangular in shape when viewed from above and a lower wall 412 that is rectangular in shape when viewed from above. The lower wall 412 and the upper wall 411 are separated by a predetermined interval in the vertical direction D1. The length direction (left-right direction D2) of the upper wall 411 is approximately the same as the length direction (left-right direction D2) of the lower wall 412. On the other hand, the dimension of the upper wall 411 in the front-back direction D3 is larger than the dimension of the lower wall 412 in the front-back direction D3.

[0157] By inserting the upper walls 411 and lower walls 412 into the outlet 14, and more specifically, into the gap 14a formed between the rear end of the first guide plate 30a and the upper end of the rear end of the frame 19 when the blades 301 of each guide plate 30 are in the closed position, the mounting part 41 is installed on the device body 10 at the position corresponding to the outlet 14. In other words, a guide plate 3 (here, the first guide plate 30a) for controlling the direction of airflow is arranged at the outlet 14, and the mounting part 41 is installed on the device body 10 at the position corresponding to the outlet 14 by inserting it between the guide plate 3 and the device body 10 (gap 14a). As a result, the airflow confined between the guide plate 3 and the device body 10 is sent to the attachment 4, thus having the advantage of easily and efficiently guiding the airflow from inside the device body 10 to the external outlet 8 via the attachment 4.

[0158] Here, with the blades 301 of each air guide plate 30 in the closed position, the airflow from the air supply section inside the device body 10 is delivered to the rear of the device body 10 via the attachment 4 installed in the aforementioned gap 14a. Furthermore, if the device body 10 is configured such that the outlet 14 is positioned on the front side of the top panel 112, the airflow from the air supply section inside the device body 10 is delivered to the front of the device body 10 via the attachment 4 installed in the aforementioned gap 14a. In other words, the mounting part 41 is installed on the device body 10 at a position corresponding to the outlet 14 to guide the airflow blown from the outlet 14 to the front or rear (here, the rear) of the device body 10. Therefore, it is easy to guide the airflow from inside the device body 10 to the external outlet 8, which is located substantially below the outlet 14, via the attachment 4, which has the advantage of easily drying objects such as shoes 7.

[0159] The mounting section 41 also has a pair of insert tabs 413, a pair of first elastic tabs 414, a pair of second elastic tabs 415, and a notch 416.

[0160] A pair of insert pieces 413, when viewed from above, are rectangular in shape and are positioned at predetermined intervals along the left-right direction D2 at the front end of the upper wall 411, protruding forward from the front end of the upper wall 411. For example... Figure 22 As shown, when the accessory 4 is installed in the position corresponding to the blow outlet 14 on the main body 10 of the device, the top end of each insert 413 is inserted below the top panel 112 (operation part 12) of the main body 10 of the device, thereby approaching the lower surface of the top panel 112. Here, "approaching" includes the insertion 413 contacting the lower surface of the top panel 112, or the distance between the insertion 413 and the lower surface of the top panel 112 being less than a threshold value (e.g., a few millimeters to tens of millimeters). Therefore, even if a downward force is applied to the nozzle side of the accessory 4 from the outside, the upward movement of the accessory 4 is restricted by the contact between the insertion 413 and the lower surface of the top panel 112, which has the advantage of easily preventing the accessory 4 from falling off the blow outlet 14.

[0161] A pair of first elastic plates 414, when viewed from above, are rectangular in shape and are positioned at predetermined intervals in the left-right direction D2 at the center of the upper wall 411 in the front-back direction D3. The rear end of each first elastic plate 414 is integrally formed with the upper wall 411, configured such that the portion other than the rear end is bent in the vertical direction D1. Furthermore, each first elastic plate 414 has an upwardly protruding claw portion 414a at its front end, which applies upward force. Figure 22As shown, when accessory 4 is installed on the device body 10 at the position corresponding to the outlet 14, the claw portion 414a is inserted into the gap between each air guide plate 30 (between the first air guide plate 30a and the second air guide plate 30b). Thus, the claw portion 414a of each first elastic piece 414 is engaged with the air guide plate 30 (here, the first air guide plate 30a). In other words, the mounting portion 41 is installed on the device body 10 at the position corresponding to the outlet 14 by engaging with the air guide plate 3 (here, the first air guide plate 30a and the second air guide plate 30b). Therefore, the mounting portion 41 is fixed to the air guide plate 3, which has the advantage of easily preventing accessory 4 from falling off the outlet 14.

[0162] A pair of second elastic plates 415, viewed from above, are rectangular in shape and are spaced apart at predetermined intervals in the left-right direction D2 at the front end of the lower wall 412. The rear end of each second elastic plate 415 is integrally formed with the lower wall 412, configured such that the portion other than the rear end is bent in the vertical direction D1. Furthermore, each second elastic plate 415 has a downwardly protruding claw portion 415a at its front end, which applies downward force. Figure 22 As shown, when the accessory 4 is installed on the device body 10 at the position corresponding to the blow-out port 14, the claw portion 415a is engaged on the inner periphery of the blow-out port 14 of the frame 19. Therefore, since the mounting portion 41 is fixed to the frame 19, it has the advantage of easily preventing the accessory 4 from falling off the blow-out port 14.

[0163] The cut 416 is positioned from the center of the front end of the upper wall 411 toward the rear end, and when viewed from above, it has a triangular shape with the front end of the upper wall 411 as its base. When the accessory 4 is installed on the main body 10 at the position corresponding to the outlet 14, the partition blade 191 provided on the frame 19 is inserted into the cut 416. Thus, the partition blade 191 restricts the movement of the upper wall 411 in the left-right direction D2, which has the advantage of making it easy to position the accessory 4 relative to the outlet 14.

[0164] The air collecting section 42 collects the airflow blown from the outlet 14 and sends it to the external outlet 8 when the mounting section 41 is installed on the device body 10 at the position corresponding to the outlet 14. In this embodiment, the air collecting section 42 is cylindrical and is arranged along the vertical direction D1 in the length direction. Furthermore, the upper end of the air collecting section 42 is connected to the rear end of the upper wall 411 and the rear end of the lower wall 412 of the mounting section 41, and the lower end faces downward. Therefore, when the accessory 4 is installed on the device body 10 at the position corresponding to the outlet 14, the airflow from the device body 10 passes between the upper wall 411 and the lower wall 412 of the mounting section 41, and after being collected in the air collecting section 42, it is sent downward from the lower end of the air collecting section 42. In this embodiment, since a flexible hose 5 with an external outlet 8 is connected to the lower end of the air collecting section 42, the airflow sent from the lower end of the air collecting section 42 flows through the flexible hose 5 and is sent out from the external outlet 8. In other words, the air collecting section 42 is configured to gather the airflow toward the mounting surface of the device body 10 (i.e., downwards) and direct it toward the external blow-out port 8. As a result, it is easy to guide the airflow from inside the device body 10 to the external blow-out port 8, which is located substantially below the blow-out port 14, via the accessory 4, which has the advantage of making it easy to dry objects such as shoes 7 that are located at a relatively low position.

[0165] Here, as described above, the lower end of the air collecting section 42 is configured to connect to the hose 5. Specifically, the lower end of the air collecting section 42 is connected to the upper end of the hose 5 by engaging with a connector 51 provided at the upper end of the hose 5. In other words, the air collecting section 42 is configured to connect to a component (here, the hose 5) having an external blowout 8. Alternatively, the connector 51 may be provided at the lower end of the air collecting section 42. In this case, the hose 5 is connected to the lower end of the air collecting section 42 by engaging the upper end of the hose 5 with the connector 51 of the air collecting section 42.

[0166] The hose 5 is a cylindrical component that is flexible and can be bent at any position along its length. In this embodiment, the hose 5 is a corrugated hose (flexible hose), but the corrugation is omitted from the drawings. As mentioned above, a connector 51 is provided at the upper end of the hose 5. Therefore, the hose 5 is configured to be connected to the air collection part 42 of the accessory 4 using the connector 51. Furthermore, the lower end of the hose 5 is configured to be connected to the nozzle 6. Specifically, the lower end of the hose 5 is connected to the nozzle 6 (here, the first nozzle 61) by engaging with the connector 63 provided at the upper end of the nozzle 6. Alternatively, the connector 63 may also be provided at the lower end of the hose 5. In this case, the nozzle 6 is connected to the lower end of the hose 5 by engaging the upper end of the nozzle 6 with the connector 63 of the hose 5.

[0167] With the nozzle 6 connected to the lower end of the hose 5, airflow from the device body 10 passes through the accessory 4 and the hose 5 and is delivered to the nozzle 6, which has an external outlet 8. Conversely, without the nozzle 6 connected to the lower end of the hose 5, airflow from the device body 10 passes through the accessory 4 and the hose 5 and is delivered from the lower end of the hose 5. In this case, the lower end of the hose 5 functions as the external outlet 8.

[0168] The nozzle 6 can be inserted into an object such as a shoe 7 or a wardrobe, and is a component used to deliver airflow from the device body 10 to the object. In this embodiment, the nozzle 6 has a first nozzle 61, which is the body of the nozzle 6, and a second nozzle 62 that is detachably mounted on the first nozzle 61.

[0169] The first nozzle 61 is a cylindrical component whose radial dimension gradually increases from its upper end to its lower end, used, for example, in the case of supplying airflow to a wardrobe to dry the interior of the wardrobe. As mentioned earlier, a connector 63 is provided at the upper end of the first nozzle 61. Therefore, the first nozzle 61 is connected to the lower end of the hose 5 by engaging the connector 63 with the lower end of the hose 5. The lower end of the first nozzle 61 is configured to connect to the upper end of the second nozzle 62. Specifically, the lower end of the first nozzle 61 is connected to the upper end of the second nozzle 62 by inserting an insertion wall (not shown) protruding circumferentially from the lower end of the first nozzle 61 into the upper end of the second nozzle 62. Alternatively, the insertion wall may be provided at the upper end of the second nozzle 62 instead of the lower end of the first nozzle 61.

[0170] The second nozzle 62 has a first cylindrical portion 621 and a second cylindrical portion 622, which are bifurcated into two rectangular sections. It is used, for example, to deliver airflow to a shoe 7 to dry the inside of the shoe 7. The upper ends of the first cylindrical portion 621 and the second cylindrical portion 622 are connected, and as previously described, they are connected to the lower end of the first nozzle 61 by inserting into the insertion wall of the lower end of the first nozzle 61. Furthermore, the lower ends of the first cylindrical portion 621 and the second cylindrical portion 622 are open, configured to deliver airflow. Both the first cylindrical portion 621 and the second cylindrical portion 622 have rectangular air outlets 623 on their side walls. Figure 23 As shown, each air outlet 623 is configured to face downwards when the first cylindrical portion 621 and the second cylindrical portion 622 are inserted into the shoe 7. Furthermore, in Figure 23The diagram shows the first cylindrical section 621, but the second cylindrical section 622 has the same configuration. Therefore, the airflow through the first cylindrical section 621 and the second cylindrical section 622 is not only delivered from the lower ends of the first cylindrical section 621 and the second cylindrical section 622, but also from each air outlet 623. Thus, the airflow can be guided to the heel side of the shoe 7 inside, which is opposite to each air outlet 623, and has the advantage of easily reducing uneven drying inside the shoe 7.

[0171] With the first nozzle 61 connected to the second nozzle 62, airflow from the main body 10 passes through the accessory 4, the hose 5, and the first nozzle 61, and is delivered from the first cylindrical portion 621 and the second cylindrical portion 622 of the second nozzle 62, respectively. Furthermore, by inserting the first cylindrical portion 621 and the second cylindrical portion 622 into the shoe 7, the interior of the shoe 7 can be dried. In this case, the lower ends of the first cylindrical portion 621 and the second cylindrical portion 622 correspond to the external air outlet 8.

[0172] On the other hand, when the first nozzle 61 is not connected to the second nozzle 62, airflow from the main body 10 of the device is delivered from the lower end of the first nozzle 61 through the accessory 4 and the hose 5. Furthermore, by inserting the lower end of the first nozzle 61 into the wardrobe, the interior of the wardrobe can be dried. In this case, the lower end of the first nozzle 61 functions as an external air outlet 8.

[0173] In addition, for example, Figure 24 As shown, the first cylindrical section 621 and the second cylindrical section 622 may also have a support section 64 with an air outlet (not shown). Furthermore, in Figure 24 The diagram shows the first cylindrical section 621, but the second cylindrical section 622 has the same configuration. The support section 64 is, for example, a roughly L-shaped cylinder viewed from above, with its upper end connected to the middle portion of the first cylindrical section 621 (or the second cylindrical section 622), configured to deliver airflow through the first cylindrical section 621 (or the second cylindrical section 622) from the air outlet. Furthermore, the support section 64 is configured to rotate around its upper end as an axis.

[0174] Therefore, for example, in the case of drying shoes 7 with a relatively shallow shaft height such as athletic shoes, by using the first shaft portion 621 (or the second shaft portion 622) while the support portion 64 is rotating in a manner that the lower end of the support portion 64 contacts the inner bottom of the shoe 7, the second nozzle 62 can be made to stand upright inside the shoe 7, thus having the advantages of easily maintaining the second nozzle 62 in a stable position and easily and efficiently drying the inside of the shoe 7.

[0175] In addition, such as Figure 25As shown, for example, when drying shoes 7 with a relatively deep shaft, such as boots, by rotating the support portion 64 with its length direction aligned with the length direction of the first cylindrical portion 621 (or the second cylindrical portion 622), and using the first cylindrical portion 621 (or the second cylindrical portion 622), it is advantageous to easily insert the second nozzle 62 into the shoe 7. Furthermore, if the support portion 64 is configured such that the air outlet is blocked while the support portion 64 is rotated as described above, airflow can be delivered to the bottom of the shoe 7 without dispersing the airflow. Thus, by having the support portion 64 in the first cylindrical portion 621 (or the second cylindrical portion 622), it is advantageous to efficiently dry the interior of the shoe 7 according to its shape.

[0176] Furthermore, in this embodiment, the hose 5 and the nozzle 6 are separate components, but they can also be configured as a single unit. In this case, the hose 5 and the nozzle 6 are equivalent to a component with an external blow-out port 8.

[0177] Furthermore, the accessory 4 in this embodiment is configured to be housed inside the main body 10 of the dehumidifier 1 when not in use, in other words, when the mounting part 41 is not installed on the main body 10 of the device body corresponding to the outlet 14. Specifically, as described above, a housing part 16 for housing the accessory 4 is provided below the filter part 13 of the housing 11. The nozzles 6 (here, the first nozzle 61 and the second nozzle 62) can be housed at the rear bottom of the housing part 16, and the accessory 4 and the hose 5 can be housed in front of the nozzles 6. Thus, by housing the accessory 4 inside the main body 10 when not in use, the user can immediately use the accessory 4 when desired, and it also has the advantage of easily preventing the accessory 4 from being lost.

[0178] The following describes the method of installing the accessory 4 according to this embodiment at a position corresponding to the air outlet 14 of the dehumidification device 1 (air supply device). First, as Figure 26As shown, each air guide plate 30 of the dehumidifier 1 is moved to the closed position. Then, the mounting part 41 of the accessory 4 is inserted into the gap 14a of the outlet 14 so that the separating blade 191 is inserted into the cut 416. At this time, a pair of insert pieces 413 of the mounting part 41 are inserted below the top panel 112 (operation part 12) of the device body 10. Furthermore, by inserting the claws 414a of a pair of first elastic pieces 414 of the mounting part 41 into the gap between each air guide plate 30, the claws 414a of each first elastic piece 414 are secured to the air guide plate 30 (here, the first air guide plate 30a). Further, the claws 415a of a pair of second elastic pieces 415 of the mounting part 41 are secured to the inner periphery of the outlet 14. Thus, the mounting part 41 is fixed to the air guide plate 30 and the frame 19, and the accessory 4 is installed on the device body 10 at a position corresponding to the outlet 14 (see reference). Figure 27 ).

[0179] When removing accessory 4 from the outlet 14, by lifting the rear end of accessory 4 upwards, the claws 414a of each first elastic piece 414 are disengaged from the gap between each air guide plate 30, and the claws 414a of each second elastic piece 415 are disengaged from the inner peripheral edge of the outlet 14 of the frame 19. Then, by moving accessory 4 backwards, accessory 4 can be removed from the position of the device body 10 corresponding to the outlet 14.

[0180] Furthermore, the timing of installing the hose 5 and nozzle 6 onto the accessory 4 can be either before installing the accessory 4 onto the device body 10 at the position corresponding to the outlet 14, or after installing the accessory 4 onto the device body 10 at the position corresponding to the outlet 14.

[0181] The features of Annex 4 involved in this embodiment will be described below.

[0182] In the air supply devices shown in related technologies, when used to dry items such as shoes or wardrobes, it is advisable to provide a connection port for connecting accessories (such as duct hoses) on the main body of the device, except for the air outlet. For example, the connection port can be located on the front or rear panel of the main body of the device and can be covered by a cover when not in use. Furthermore, when using the connection port, by removing the cover and installing the accessory, the airflow delivered from the main body of the device through the connection port and the accessory can be used to dry shoes or wardrobes.

[0183] However, this method adds a connection port to the main body of the device, increasing manufacturing time. Furthermore, the connection port can cause design damage to the main body. Moreover, without the connection port, to prevent airflow from being dispersed by simultaneously flowing towards both the outlet and the connection port, a cover or similar device must be installed to shield the connection port, compromising user convenience.

[0184] In contrast, in Annex 4 of this embodiment, simply installing it at the position corresponding to the outlet 14 originally included in the main body of the air supply device allows airflow from the main body 10 to be used to dry the object. Therefore, in Annex 4 of this embodiment, there is no need to provide a connection port on the main body 10 other than the outlet 14, thus having the advantage of not increasing manufacturing time for the main body 10. Furthermore, since Annex 4 of this embodiment does not require a connection port on the main body 10, there is no problem of the connection port compromising the design of the main body 10. Moreover, in Annex 4 of this embodiment, when Annex 4 is not in use, there is no need to cover the connection port, thus avoiding any problem affecting user convenience. Therefore, Annex 4 of this embodiment has the advantages of preventing increased manufacturing time for the main body 10 while minimizing damage to its design.

[0185] [5] Variations The following are examples of variations of the embodiments. The variations described below can be appropriately combined and applied.

[0186] In this embodiment, the opening surface of the drain outlet 20 of the drain tank 2 is approximately parallel to the bottom wall 211 of the tank body 21, but it is not limited to this. For example, the opening surface of the drain outlet 20 may gradually slope downwards from the inside to the outside of the tank body 21. In this manner, when the tank body 21 is tilted to drain condensate, a gap can be created between the drain cover 25 and the tank body 21 without significantly tilting the tank body 21, compared to the case where the opening surface of the drain outlet 20 is not tilted, thus facilitating the drainage of condensate.

[0187] Furthermore, in this embodiment, the left wall 215 of the main body 21 of the drain tank 2, that is, the wall that becomes the bottom of the main body 21 in the draining posture, is approximately perpendicular to the bottom wall 211, but is not limited to this. For example, the left wall 215 of the main body 21 (the wall that becomes the bottom when draining condensate) may also be tilted to the right (from the outside to the inside of the main body 21) at a predetermined angle (e.g., 5 degrees or more) from the upper end to the lower end. In this manner, when the main body 21 is tilted to drain condensate, compared to the case where the left wall 215 of the main body 21 is not tilted, the condensate in the main body 21 is more likely to flow along the tilt towards the drain outlet 20, which has the advantage that condensate is less likely to remain in the main body 21.

[0188] Furthermore, in this embodiment, a water inlet 223 is provided so that condensed water dripping onto the lid 22 can flow along the inner wall of the body 21, but this is not a limitation. For example, the water inlet 223 can also be located above the second arm 233 so that it overlaps with the second arm 233 of the handle 23 when viewed from above. In this manner, condensed water dripping from the dehumidifying section onto the lid 22 flows through the water inlet 223 along the second arm 233 to the bottom wall 211 of the body 21. Therefore, by suppressing the height of the condensed water falling to the bottom wall 211, it has the advantage of easily suppressing the impact sound generated when the condensed water falls to the bottom wall 211.

[0189] Furthermore, in this embodiment, such as Figure 28 As shown, a plurality of through holes 235a may be provided on the suppression part 235. In this manner, similar to the case where multiple holes 235a are not provided on the suppression part 235, the flow momentum of the condensate can be suppressed by the suppression part 235 when the tank body 21 is tilted to discharge the condensate inside the tank body 21. Furthermore, in this manner, compared to the case where multiple holes 235a are not provided on the suppression part 235, the condensate can pass through multiple holes 235a, thus increasing the drainage volume of the condensate per unit time. Therefore, this manner has the advantage of being able to suppress the flow momentum of the condensate while easily ensuring a sufficient drainage volume of the condensate per unit time when discharging the condensate.

[0190] Furthermore, in this embodiment, the handle 23 has a pair of first arms 232 and a pair of second arms 233, but is not limited thereto. For example, the handle 23 may be configured to rotate the grip portion 231 about the shaft portion 234 as the central axis, or it may have only one first arm 232 and one second arm 233.

[0191] Furthermore, in this embodiment, the handle 23 is configured to allow the grip portion 231 to rotate about the front-back direction D3, but it is not limited to this. For example, the handle 23 may also be configured to allow the grip portion 231 to rotate about the left-right direction D2.

[0192] Furthermore, in this embodiment, the grip 231 can be displaced in the vertical direction D1 by rotating the handle 23, but it is not limited to this. For example, the grip 231 can also be displaced in the vertical direction D1 by using a sliding mechanism or the like to move linearly.

[0193] Furthermore, in this embodiment, the water stored in the drain tank 2 is condensed water, but it is not limited to this. For example, the water stored in the drain tank 2 may also be water containing dirt components generated within the device body 10 while it is housed within the device body 10.

[0194] In this embodiment, the air supply device including the air guide plate 3 is a dehumidification device 1, but it is not limited to this. The air supply device can be any device that can blow airflow from inside the device body 10 through the air outlet 14, such as an air purifier, an air conditioner, an aroma diffuser, or a cooler.

[0195] In this embodiment, the hose 5 and the accessory 4 are separate components, but they can also be integrated. In this case, the hose 5 and the accessory 4 are equivalent to accessories for an air supply device. Furthermore, the hose 5, the nozzle 6, and the accessory 4 can also be integrated. In this case, the hose 5, the nozzle 6, and the accessory 4 are equivalent to accessories for an air supply device.

[0196] Furthermore, in this embodiment, the air supply device with the air supply device accessory 4 is a dehumidifier 1, but it is not limited to this. The air supply device can be any device that can blow airflow from inside the device body 10 through the air outlet 14, such as an air purifier, an air conditioner, an aroma diffuser, or a cooler.
