<Modification>
Although the first and second embodiments have been described above, the present invention is not limited to these embodiments, and may be modified as follows. Also, the embodiment may be combined with a modified example, or a combination of modified examples.
Further, examples not described in the embodiments and modifications, and design changes within the scope of the invention are also included in the present invention.

1. Orientation of resin pipe (1) In the embodiment, a plurality of resin pipes were arranged so as to extend in the vertical direction. It may be inclined with respect to the horizontal direction, may be arranged with an inclination with respect to the front and back direction of the device, or may be arranged with an inclination with respect to the front and back direction, or may be arranged with an inclination across the vertical direction, the horizontal direction, and the front and back direction. may be distributed.
(2) Pipe group In the embodiment, one pipe group is composed of four resin pipes, but may be one or more than four.
The group of pipes is supported in a state of being overlapped in the intake direction, but is supported in a state (stepped state) that is gradually displaced in the arrangement direction to the extent that the heat exchange efficiency is not affected (within the range that satisfies the requirements). good too.
The pipe groups are supported in close contact with each other in the intake direction, but they may be supported at intervals in the intake direction, for example. In this case, although the dimension of the heat exchanger in the intake direction is increased, the heat exchange efficiency is improved.
(3) Cross-sectional shape In the embodiment, the cross-sectional shape is rectangular, but it may be circular, rectangular, or other shape. However, considering the area in contact with air, the cross-sectional area, the size of the unit, etc., a rectangular cross-sectional shape is preferable.
(4) Length The length of the resin pipe is not particularly specified, but it may be longer than the axial length of the resin pipe in the lattice hole portion. The length of the resin pipe referred to here refers to the length of the area in contact with air, and does not include the length within the support portion.
It is preferable that the lattice hole portion is located in the middle portion of the resin pipe in the pipe axial direction. Here, the intermediate portion refers to the entire area or a partial area within the range of 3/10 to 7/10 from the upstream side in the pipe axial direction of the resin pipe (not including the inside of the support portion).

2. Dehumidifying Rotor The dehumidifying rotor is driven to rotate around the outer periphery of the dehumidifying frame by attaching the water absorbing body to the dehumidifying frame, but it may be driven to rotate by a dehumidifying shaft placed in the center of the water absorbing body.
Looking at the disk-shaped water absorber from the front side (air inlet side), one semicircular portion whose diameter is a straight line parallel to the pipe axial direction of the resin pipe overlaps with the heat exchanger, and the other semicircular portion is about 2/5 overlaps the receiver. These ratios may be appropriately changed depending on the spacing, size, number, etc. of the resin pipes of the heat exchanger.

The dehumidifying rotor is supported by the circumferential wall portion of the tubular portion in a state in which the dehumidifying frame is supported by the dehumidifying shaft via the water absorber. However, the dehumidifying rotor may be supported from the back side of the dehumidifying frame (the side of the cylindrical portion where the extended portion does not exist). The support is configured by, for example, an overhanging portion that overhangs the surface side of the circumferential wall portion of the cylindrical portion. The amount of protrusion of the overhanging portion is limited within a range in which the dehumidifying rotor can be arranged in the cylindrical portion when the overhanging portion is provided integrally with the cylindrical portion, and is particularly limited when the overhanging portion is not provided integrally with the cylindrical portion. not a thing However, if it extends beyond the dehumidification frame to a position where it overlaps with the water absorber, the amount of air passing through the water absorber decreases, which is not preferable. The projecting portion may be arranged to face the dehumidification frame, and may be provided integrally or separately with, for example, the heater, the communication passage, the main fan unit, etc., other than the supporting member.

3. Entire Supporting Member (1) The supporting member may support at least the dehumidifying rotor, and may not support other units such as a heater.
However, when focusing on the mounting method of the dehumidifying rotor and the heater, the supporting member needs to support the dehumidifying rotor and the heater. Similarly, when focusing on the mounting method of the dehumidification rotor, the heater and the receiver, the support member needs to support the dehumidification rotor, the heater and the receiver.
Also, when focusing on the structure of the upper guide space that guides 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.
Also, 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 related to the support of the heater, receiver, and upper cover, but the lower cover and heat exchanger. need support.

(2) Extended Portion The support member had three extended portions, but the number of extended portions may be one, two, or four or more as long as the dehumidifying rotor can be supported. . Considering the amount of air supplied to the dehumidifying rotor, the number of extending portions is preferably four or less.
In the embodiment, the receiver is brought into contact with the extended portion, but the receiver does not have to be brought into contact with the extended portion if the attachment of the receiver is not the focus. However, considering the amount of air that passes through the dehumidification rotor, it is preferable that the two abut within the receiver.
The extending portion integrally having the comb portion extends in a direction orthogonal to the pipe axial direction of the resin pipe, but may extend in a direction not orthogonal to the pipe axial direction of the resin pipe. In this case, the teeth may be provided so that the positions of the teeth are stepped with respect to the resin pipe. This stepped shape also corresponds to an example of "having a plurality of teeth along the direction in which the resin pipes are arranged".

(3) Crosspiece Portion The horizontal crosspiece portion integrally having the comb portion extends in a direction orthogonal to the pipe axial direction of the resin pipe, but may extend in a direction not orthogonal to the pipe axial direction of the resin pipe. In this case, the teeth may be provided so that the positions of the teeth are stepped with respect to the resin pipe. It should be noted that extending in such a non-orthogonal direction also corresponds to an example of "stretching along the direction in which the resin pipes are arranged side by side."
In the embodiment, the extending portion having the comb portion and the horizontal rail portion are positioned on one straight line, but the horizontal rail portion and the extending portion may intersect, for example, in a "V" shape. In this case, the teeth of the transverse beam portion and the teeth of the extension portion can be provided stepwise as described above.
In the embodiment, there is one crosspiece, but if the length of the resin pipe is increased depending on the size of the dehumidifier, dehumidification performance, etc., a plurality of crosspieces may be provided.

(4) Comb Portion and Teeth Although the comb portion in the embodiment is provided integrally with the extending portion and the horizontal rail portion, it may be configured separately and then attached to the extending portion and the horizontal rail portion. When the support member is injection-molded using a resin material, it is advantageous in terms of cost to integrally mold the comb portion.
The tooth of the embodiment has a rectangular shape (including cases where the corners are rounded) that is long in the pipe axial direction of the resin pipe, but other shapes such as a rectangular shape, a circular shape, and an elliptical shape are also possible. can be Considering stress concentration at the contact portion with the resin pipe, it is preferable to have a shape that makes line contact or surface contact with the resin pipe. In consideration of the arrangement of the resin pipe, it is preferable that the tip of the tooth is tapered.

A resin material having poor heat resistance may be used as the second shaft portion, or the first shaft portion and the second shaft portion may be integrally formed of a general resin material.
Moreover, when heat resistance is required for the second shaft portion, heat-resistant resin materials such as polyethylene terephthalate (PET) and polyphenylene sulfide (PPS) can be used in addition to PBT. Furthermore, a metal material can be used as the second shaft, and for example, it can be integrated with the first shaft by insert molding.

(6) Cylindrical portion The cylindrical portion is recessed toward the front side with respect to the first base portion of the base portion. It may be a structure in which the front side and the back side are recessed from one base portion.
The tubular portion has a cylindrical shape corresponding to the outer peripheral shape of the dehumidifying rotor. However, when the dehumidifying frame of the dehumidifying rotor is supported by the inner peripheral surface of the tubular portion, the tubular portion preferably has an inner peripheral surface shaped to contact the outer periphery of the dehumidifying frame at at least three points.

(7) Second Shaft The second shaft of the embodiment has a main hole and a secondary hole, and is fixed to the connecting portion of the support member by two screws. Alternatively, for example, a pin formed integrally with the connecting portion may be used. In the embodiment, the protruding portion of the second shaft is fixed by screws. The body never rotates. However, when the second shaft rotates, a rotational load acts on the chipped portion via the protrusion, and it is preferable to fix the protrusion in consideration of durability.
Moreover, the second shaft may be fixed coaxially with the first shaft, and other structures and fixing methods may be used. 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.
