The heat exchange unit 39 is installed so that the teeth 119a of the portion 119 are located. Thereby, even if the resin pipe 37 is deformed due to long-term use, contact between the laterally adjacent pipe groups 38 can be restricted. Thereby, the amount of air passing between the pipe groups 38 can be maintained constant even when used for a long time.
The comb portions 109 and 119 are provided by using the extension portion 115A of the cylindrical portion 111, and the resistance of air passing between the pipe groups 38 is reduced compared to the case where the comb portion 119 is provided at other portions. it can.

<Modification>
As mentioned above, although 1st and 2nd embodiment was described, it is not restricted to these embodiments, For example, the following modifications may be sufficient. In addition, the embodiment, the modification, and the modifications may be combined.
In addition, even if there is an example not described in the embodiment or the modification, or a design change in a range not departing from the gist, the present invention is included.

1. Resin pipe (1) direction In the embodiment, the plurality of resin pipes are arranged to extend in the vertical direction, but the resin pipes may be arranged to be inclined with respect to the vertical direction, or the lateral direction or It may be arranged to be inclined to the lateral direction, may be arranged to be inclined to the front or back direction of the device or to the front or back direction, or may be inclined to straddle in the vertical direction, the lateral direction and the front or back direction It may be distributed.
(2) Pipe Group In the embodiment, one pipe group is constituted by four resin pipes, but a plurality of pipes other than one or four may be used.
The pipe group is supported in a state of overlapping in the intake direction, but is supported in a state of being gradually displaced in the direction of arrangement (stepwise state) to an extent that the heat exchange efficiency is not affected (within the range where the request can be satisfied). It is also good.
The pipe group is supported in close contact with the intake direction, but may be supported, for example, at intervals in the intake direction. In this case, the dimension in the intake direction of the heat exchanger is increased, but the heat exchange efficiency is improved.
(3) Cross-sectional shape In embodiment, although the cross-sectional shape is carrying out the square shape, other shapes, such as circular shape and rectangular shape, may be sufficient. However, in consideration of the area in contact with air, the cross-sectional area, the size as a unit, etc., a rectangular cross-sectional shape is preferable.
(4) Length Although the length of the resin pipe is not particularly specified, it may be equal to or more than the length in the pipe axial direction of the resin pipe in the lattice hole portion. In addition, the length of the resin pipe here means the length of the area | region which touches air, and the length in a support part is not included.
It is preferable that the lattice hole portion be located at an intermediate portion in the axial direction of the resin pipe. In addition, the middle part said here means the whole area | region or partial area | region within the range of 3/10-7/10 from the upstream of the pipe axial direction of resin pipe (not including the inside of a support part).

2. Dehumidifying Rotor The dehumidifying rotor is mounted on the dehumidifying frame and driven to rotate on the outer periphery of the dehumidifying frame, but may be driven to rotate by the dehumidifying shaft disposed at the center of the water absorbing body.
When a disk-like water absorbent body is viewed from the front side (intake port side), one semicircular portion whose diameter is a straight line parallel to the pipe axial direction of the resin pipe overlaps the heat exchanger, and the other semicircular portion is about 2/5 overlaps with the receiver. These ratios may be suitably changed according to the space | interval of the resin pipe of a heat exchanger, a magnitude | size, a number, etc.

  The dehumidifying rotor is supported by the circumferential wall portion of the cylindrical portion in a state where the dehumidifying frame is supported by the dehumidifying shaft via the water absorbing body. However, the dehumidifying rotor may be supported by the dehumidifying frame from the back side (the side of the cylindrical portion where no extending portion is present). As a support, for example, it comprises an overhanging portion that overhangs the surface side of the circumferential wall portion of the cylindrical portion. The amount of overhang of the overhanging portion is particularly limited in the case where the dehumidifying rotor can be disposed in the cylindrical portion when the overhanging portion is integrally provided in the cylindrical portion, and in the case where the overhanging portion is not integrally provided in the cylindrical portion. It is not a thing. However, when the dehumidifying frame is extended 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 opposite to the dehumidifying frame, and may be integrally or separately provided, for example, in the heater, the communication passage, the main fan unit, etc., in addition to the support member.

3. Support Member (1) Overall The support member may support at least the dehumidifying rotor, and may not support other units such as a heater, for example.
However, when paying attention to the mounting method of the dehumidification rotor and the heater, the support member needs to support the dehumidification rotor and the heater. Similarly, when focusing on 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.
In addition, 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.
Also, when focusing on the structure of the lower guide space for guiding the air that has passed through the heat exchanger to the communication path, the support member is not related to the support of the heater, receiver and upper cover. Support is needed.

(2) Stretched Portion The support member has three stretched portions, but one, two, or four or more stretched portions may be provided as long as the dehumidifying rotor can be supported. . In consideration of the amount of air supplied to the dehumidification rotor, the number of extension parts is preferably four or less.
In the embodiment, the receiver is in contact with the extended portion, but when not focusing on the attachment of the receiver, the receiver may not be in contact with the extended portion. However, in consideration of the amount of air passing through the dehumidifying rotor, it is preferable that the both be in contact within the receiver.
Although the extension part which has a comb part integrally extends in the direction which intersects perpendicularly with the pipe axial direction of a resin pipe, it may extend in the direction which does not intersect with the pipe axial direction of a resin pipe. In this case, the teeth may be provided such that the positions of the teeth are stepped with respect to the resin pipe. In addition, also in the case of this step shape, it corresponds to an example of “having a plurality of teeth along the direction in which resin pipes are arranged”.

(3) Horizontal rail portion The horizontal rail portion integrally having the comb portion extends in the direction orthogonal to the pipe axial direction of the resin pipe, but may extend in the direction not orthogonal to the pipe axial direction of the resin pipe. In this case, the teeth may be provided such that the positions of the teeth are stepped with respect to the resin pipe. In addition, also when extending | stretching in such a direction which does not cross orthogonally, it corresponds to an example of "stretching along the parallel direction of resin pipe."
In the embodiment, the extension portion having the comb portion and the cross rail portion are located on a straight line, but the cross rail portion and the extension portion may cross each other, for example, in a “V” shape. In this case, the teeth of the cross-bar portion and the teeth of the extension portion can be implemented by providing steps as described above.
In the embodiment, one cross rail portion is provided. However, when the resin pipe is elongated depending on the size of the dehumidifier, the dehumidification performance, and the like, a plurality of cross rail portions may be provided.

(4) Comb part and tooth Although the comb part of an embodiment is provided in one to an extension part and a cross rail part, after constituting separately, it may be made to attach to an extension part and a cross rail part. When the support member is injection molded using a resin material tail, it is more cost effective to integrally form the comb portion.
The teeth of the embodiment have a rectangular shape (including the case where the corner is rounded) long in the pipe axial direction of the resin pipe, but other shapes such as, for example, a rectangular shape, a circular shape, and an oval shape It may be In addition, in consideration of stress concentration at the contact portion with the resin pipe, a shape in which the resin pipe is in line contact or surface contact is preferable. In addition, in consideration of the disposition of the resin pipe, it is preferable that the extension end of the tooth be tapered.

(5) Support shaft The support shaft of the embodiment is composed of the first shaft portion and the 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 A resin material with 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.
Further, 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. Furthermore, it is also possible to use a metal material as the second shaft portion, for example, to integrate with the first shaft portion by insert molding.

(6) Tubular part The tubular part is recessed on the front side with reference to the first base part of the base part, but for example, the tubular part may be recessed on the back side from the first base part, or The structure may be recessed from the base portion to the front side and the back side.
The cylindrical portion has a cylindrical shape corresponding to the outer peripheral shape of the dehumidifying rotor, but the cylindrical portion may have a shape such as a square cylindrical portion as long as the dehumidifying rotor can rotate within the cylindrical portion. However, when the dehumidifying frame of the dehumidifying rotor is supported by the inner peripheral surface of the cylindrical portion, the cylindrical portion having an inner peripheral surface having a shape 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 by two screws, but instead of the screw for the sub hole Alternatively, for example, a pin integrally formed on the connecting portion can be used. In the embodiment, the protrusion of the second shaft is fixed by a screw, but when the protrusion is fitted in the notch of the first shaft, the protrusion is not fixed but the second shaft is fixed. The body does not rotate. However, when the second shaft rotates, the rotational load acts on the notch through the protrusion, and in consideration of durability, it is preferable to fix the protrusion.
Further, the second shaft may be fixed coaxially with the first shaft, and may have other structure and fixing method. As another structure, it has a projection which protrudes in two directions at one end of the shaft, and the projection may be fixed by a screw or the like.

4. Sensor The fall sensor of the embodiment is provided along with the temperature sensor near the middle in the vertical direction of the support member, but may be provided, for example, on the lower side of the support member. In this case, when the temperature sensor can not be disposed on the lower side, the fall sensor and the substrate of the temperature sensor may be connected by wiring.
