<Modification>
Although the first and second embodiments have been described above, the present invention is not limited to these embodiments, and may be, for example, the following modifications. Further, a combination of the embodiment, the modified examples, and the modified examples may be used.
In addition, examples that are not described in the embodiments and modified examples, and design changes that do not depart from the gist are also included in the present invention.

1. Orientation of Resin Pipe (1) In the embodiment, the plurality of resin pipes are arranged so as to extend in the vertical direction. However, the resin pipe may be arranged to be inclined with respect to the vertical direction, It may be arranged to be inclined with respect to the horizontal direction, may be arranged to be inclined with respect to the front and back direction or the front and back direction of the device, or may be inclined so as to straddle in the vertical direction, the horizontal direction and the front and back direction May be arranged.
(2) Pipe Group In the embodiment, one pipe group is configured by four resin pipes, but may be one or a plurality of pipes other than four.
The pipe group is supported in a state of being overlapped in the intake direction, but is supported in a state in which the heat exchange efficiency is not affected (within a range that can satisfy the requirement) and is gradually shifted in the arrangement direction (a staircase state). Is also good.
The pipe group is supported in a state of being closely attached to the intake direction, but may be supported at intervals in the intake direction, for example. In this case, the size of the heat exchanger in the intake direction is increased, but the heat exchange efficiency is improved.
(3) Cross-sectional shape In the embodiment, the cross-sectional shape is a square shape, but may be another shape such as a circular shape or a rectangular shape. However, in consideration of the area in contact with air, the cross-sectional area, the size as a unit, and the like, a rectangular cross-sectional shape is preferable.
(4) Length The length of the resin pipe is not particularly defined, but may be any length as long as it is equal to or greater than the length of the resin pipe at the lattice hole in the pipe axis direction. Note that the length of the resin pipe referred to here refers to the length of an area that comes into contact with air, and does not include the length in the support portion.
The lattice hole is preferably located at an intermediate portion of the resin pipe in the pipe axis direction. Here, the intermediate portion refers to an entire region or a partial region within a range of 3/10 to 7/10 from the upstream side in the pipe axis direction of the resin pipe (not including the inside of the support portion).

2. Dehumidification rotor The dehumidification rotor has the water absorber mounted on the dehumidification frame and is driven to rotate around the outer periphery of the dehumidification frame. However, the dehumidification rotor may be driven to rotate by a dehumidification shaft disposed at the center of the water absorber.
When the disc-shaped water absorbing body is viewed from the front side (inlet side), one semi-circular portion having a diameter in a straight line parallel to the pipe axis direction of the resin pipe overlaps with the heat exchanger, and the other semi-circular portion has an approximately 2/5 overlap with the receiver. These ratios may be appropriately changed according to the interval, size, number, and the like of the resin pipes of the heat exchanger.

  The dehumidifying rotor is supported by the circumferential wall of the cylindrical portion in a state where the dehumidifying frame is supported by the dehumidifying shaft via the water absorbing body. However, in the dehumidifying rotor, the dehumidifying frame may be supported from the back side (the side where the extending portion in the cylindrical portion does not exist). As the support, for example, it is constituted by a projecting portion projecting to the surface side of the circumferential wall portion of the cylindrical portion. In addition, the amount of overhang of the overhang portion is particularly limited when the overhang portion is not provided integrally with the tube portion within a range where the dehumidifying rotor can be arranged in the tube portion when the overhang portion is provided integrally with the tube portion. Not something. However, if it extends beyond the dehumidifying frame to a position overlapping with the water absorbing body, the amount of air passing through the water absorbing body decreases, which is not preferable. The overhanging portion may be disposed so as to face the dehumidifying frame, and may be provided integrally or separately with, for example, a heater, a communication passage, a main fan unit, and the like, in addition to the support member.

3. Support Member (1) Overall The support member only needs to support at least the dehumidifying rotor, and need not support other units such as a heater, for example.
However, when paying attention to the mounting method of the dehumidifying rotor and the heater, the support member needs to support the dehumidifying rotor and the heater. Similarly, when paying attention to the mounting method of the dehumidifying rotor, the heater, and the receiver, the support member needs to support the dehumidifying rotor, the heater, and the receiver.
When focusing on the structure of the upper guide space for guiding the air from the heater to the heat exchanger, the support member needs to support the upper cover and the heat exchanger regardless of the support of the heater and the receiver. Become.
When focusing on the structure of the lower guide space that guides the air that has passed through the heat exchanger to the communication passage, the support member is not connected to the heater, the receiver, and the upper cover, regardless of whether the lower cover or the heat exchanger is supported. Support is needed.

(2) Stretched portion The support member had three stretched portions. However, as long as the supporting member can support the dehumidifying rotor, the stretched portion may be one, two, or four or more. . Considering the amount of air supplied to the dehumidifying rotor, the number of stretched portions is preferably four or less.
In the embodiment, the receiver is brought into contact with the extended portion. However, if attention is not paid to mounting the receiver, the receiver need not be brought into contact with the extended portion. However, in consideration of the amount of air passing through the dehumidifying rotor, it is preferable that the two contact each other in the receiver.
The extending portion integrally having the comb portion extends in a direction orthogonal to the pipe axis direction of the resin pipe, but may extend in a direction not orthogonal to the pipe axis direction of the resin pipe. In this case, the teeth may be provided so that the positions of the teeth are stepwise with respect to the resin pipe. Note that this step-like case also corresponds to an example of “having a plurality of teeth along the direction in which the resin pipes are arranged”.

(3) Horizontal Cross Section The horizontal cross section integrally having the comb section extends in a direction orthogonal to the pipe axis direction of the resin pipe, but may extend in a direction not orthogonal to the pipe axis direction of the resin pipe. In this case, the teeth may be provided so that the positions of the teeth are stepwise with respect to the resin pipe. In addition, the case of extending in such a direction that is not orthogonal also corresponds to an example of “extending along the direction in which the resin pipes are arranged”.
In the embodiment, the extending portion having the comb portion and the horizontal portion are located on one straight line, but the horizontal portion and the extending portion may intersect, for example, in a “V” shape. In this case, the teeth of the crosspiece portion and the teeth of the extended portion can be implemented by providing the teeth in a stepwise manner as described above.
In the embodiment, the number of the crosspieces is one. However, when the length of the resin pipe is increased depending on the size of the dehumidifier, the dehumidification performance, and the like, a plurality of the crosspieces may be provided.

(4) Comb portion and tooth The comb portion of the embodiment is provided integrally with the extending portion and the cross beam portion, but may be configured separately and then attached to the extending portion and the cross beam portion. When the support member is injection-molded using a resin material tail, it is more cost-effective to integrally mold the comb portion.
The teeth of the embodiment have a rectangular shape (including a case where the corners are round) which is long in the pipe axis direction of the resin pipe, but other shapes such as a square shape, a circular shape, and an oval shape It may be. In consideration of the concentration of stress at the contact portion with the resin pipe, a shape that makes line contact or surface contact with the resin pipe is preferable. In addition, it is preferable that the extending end portion of the tooth be tapered in consideration of the arrangement of the resin pipe.

(5) Support Shaft The support shaft of the embodiment is composed of a first shaft portion and a second shaft portion, and the second shaft portion is a heat-resistant portion. For example, when the heater is not connected to the support shaft. Alternatively, a resin material having inferior heat resistance may be used for the second shaft portion, or the first shaft portion and the second shaft portion may be integrally provided by a general resin material.
When heat resistance is required for the second shaft portion, a heat-resistant resin material such as polyethylene terephthalate (PET) or polyphenylene sulfide (PPS) can be used in addition to PBT. Further, a metal material can be used as the second shaft portion, and for example, it can be integrated with the first shaft portion by insert molding.

(6) Tube part The tube part is recessed on the front side with reference to the first base part of the base part. For example, the tube part may be configured to be recessed on the back side from the first base part. A structure in which one base portion is recessed into the front side and the back side may be used.
Although the cylindrical portion has a cylindrical shape corresponding to the outer peripheral shape of the dehumidifying rotor, it is sufficient that the dehumidifying rotor can rotate inside the cylindrical portion. For example, the cylindrical portion may have a shape such as a square cylindrical portion. However, when supporting the dehumidifying frame of the dehumidifying rotor on the inner peripheral surface of the cylindrical portion, a cylindrical portion having an inner peripheral surface that is in contact with the outer periphery of the dehumidifying frame at at least three points is preferable.

(7) Second Shaft The second shaft of the embodiment has a main hole and a sub-hole, and is fixed to the connecting portion of the support member with two screws, but instead of the screw for the sub-hole. Alternatively, for example, a pin integrally formed on the connecting portion may be used. In the embodiment, the protruding portion of the second shaft body is fixed by a screw. However, when the protruding portion is fitted in the notch of the first shaft portion, the second shaft is not fixed even if the protruding portion is not fixed. The body does not rotate. However, in the case where the second shaft body rotates, a load of rotation acts on the notch via the protrusion, and it is preferable to fix the protrusion in consideration of durability.
In addition, the second shaft body may have a shaft portion that is fixed coaxially with the first shaft portion, and may have another structure and a fixing method. As another structure, one end of the shaft portion may have a protrusion projecting in two directions, and the protrusion may be fixed by a screw or the like.

4. Sensor The fall sensor of the embodiment is provided together with the temperature sensor near the middle of the support member in the vertical direction, but may be provided, for example, on the lower side of the support member. In this case, when the temperature sensor cannot be arranged on the lower side, the fall sensor and the substrate of the temperature sensor may be connected by wiring.
Although one falling sensor is provided together with the temperature sensor in the embodiment, a plurality of falling sensors may be provided. For example, in the case of two, it may be provided in the middle and the lower part in the vertical direction of the support member.

5. Housing (1) Structure The housing of the embodiment is composed of the front case, the back case, and the decorative plate, but may be composed of the front case and the back case. It may be composed of four members, a back case and a pair of decorative boards.
The front case and the back case of the embodiment are configured so that the housing is divided into two at the center in the front and back direction, but one of the front case and the back case is configured to be larger in the front and back direction than the other. May be done.
Although the housing of the embodiment is provided with the water tank on the front side so that it can be taken in and out, the housing may be provided with the water tank on the back side so that it can be taken in and out.

(2) Operation Unit In the operation unit of the embodiment, the operation board is fixed to the bottom wall of the recess of the front case. The recess has an opening on the back side, but may be a recess having four side walls.
Although the bottom wall is provided in a horizontal shape, the bottom wall may be provided in an inclined shape downward on the back side. The inclined shape can prevent moisture from being guided to the front side along the bottom wall and flowing to the operation board side. Although the operation unit in the embodiment is provided on the top wall of the front case, for example, it may be provided on the front wall.
