Description

  The present invention relates to a dehumidifier that removes moisture in the air.

As a dehumidifier, for example, there is a so-called decant type in which moisture is absorbed by a dehumidification rotor having a disc-shaped moisture absorbent, and the absorbed moisture is condensed by a heat exchanger (for example, Patent Document 1).
The dehumidifier of Patent Document 1 includes a “desicant wheel module including a base and a desiccant wheel rotatably attached to the base, a first airflow generation module that supplies a first airflow that passes through the desiccant wheel, A circulation airflow tube fixed to the base and having an airflow tube inlet and an airflow tube outlet; a second airflow generation module connected to the circulation airflow tube for supplying a second airflow; and the desiccant connected to the circulation airflow tube A heater that heats the second airflow passing through the wheel; and a heat exchanger that is fixed to the base and guides the second airflow from the desiccant wheel, the heat exchanger at the outlet of the airflow tube A frame having a connected air inlet, an air outlet connected to the airflow pipe inlet, and a liquid outlet located at the bottom; and a frame fixed to the frame and arranged substantially horizontally. A main body that is internally spaced apart from each other to form a first flow channel and each forms a plurality of second flow channels in communication with both the air inlet and the air outlet; A plurality of heat exchange plate-like tubes each having one or more dividing walls located between two adjacent to each other in the plurality of second flow channels. ”(Claim 13) .
“The heat exchanger 10 further includes a central grill 15 located between the upper grill 13 and the lower grill 14 in the opening 1114 of the frame main body 111. The central grill 15 is a central portion of the heat exchange plate tube 12. Is fixed to improve the coupling stability between the heat exchange plate-like tube 12 and the frame body 111. ”(paragraph 33).
In the dehumidifier described in Patent Document 1, since the heat exchange plate-like tube is fixed by the central grill, even if the heat exchange plate-like tube using a resin material is used for a long time, the amount of deformation can be reduced. .
The “heat exchange plate tube” in Patent Document 1 corresponds to the “resin pipe” of the present invention.

Utility Model Registration No. 3182805

However, in the dehumidifier described in Patent Document 1, a heat exchanger is fixed to a support member that supports the dehumidification rotor after a resin pipe is attached to the frame body to form a heat exchanger. For this reason, the attachment cost to the support member side of the resin pipe is increasing.
An object of the present invention is to provide a dehumidifier that can reduce deformation of a resin pipe with time and can be attached at a low cost.

  A dehumidifier according to the present invention includes a dehumidification rotor, a support member having a support shaft that rotatably supports the dehumidification rotor, and a heater that heats the dehumidification rotor and is attached to the support shaft, The support shaft has a heat-resistant portion at a portion where the heater is mounted.

  According to the above-described configuration, since the resin pipe is directly attached to the support member having the comb portion, the resin pipe is less likely to be deformed with time and can be attached at low cost.

<Modification>
The first and second embodiments have been described above. However, the present invention is not limited to these embodiments, and for example, the following modifications may be used. Moreover, what combined embodiment, a modification, and modifications may be sufficient.
In addition, examples that are not described in the embodiments and modifications, and design changes that do not depart from the gist are also included in the present invention.

1. For resin pipe (1) In the embodiment, the plurality of resin pipes are arranged so as to extend in the vertical direction. However, the resin pipes 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 of the apparatus or the front-and-back direction, It may be arranged.
(2) Pipe group In the embodiment, one pipe group is composed of four resin pipes, but it may be one or a plurality of pipes other than four.
The pipe group is supported in a state where it overlaps in the intake direction, but is supported in a state (step state) that is gradually shifted in the installation direction to the extent that it does not affect the heat exchange efficiency (within a range that can satisfy the requirements). Also good.
The pipe group is supported in close contact with the intake direction, but may be supported with an interval 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, but other shapes such as a circular shape and a rectangular shape may be used. 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 defined, it may be longer than the length of the resin pipe in the pipe hole direction in the lattice hole. In addition, the length of the resin pipe here refers to the length of the area in contact with air, and does not include the length in the support portion.
It is preferable that the lattice hole is located at an intermediate portion of the resin pipe in the pipe axial direction. In addition, an intermediate part here means the whole area | region or a partial area | region in the range of 3 / 10-7 / 10 from the upstream of the pipe axial direction of a resin pipe (it does not include the inside of a support part).

2. Dehumidification rotor The dehumidification rotor is driven to rotate on the outer periphery of the dehumidification frame with the water absorption body attached to the dehumidification frame. However, the dehumidification rotor may be rotationally driven by a dehumidification shaft disposed at the center of the water absorption body.
When the disk-shaped water absorber is viewed from the front side (intake port side), one semicircular part with a diameter parallel to the pipe axis direction of the resin pipe overlaps with the heat exchanger, and about half of the other semicircular part 2/5 overlaps with the receiver. These ratios may be changed as appropriate according to the interval, size, number, etc. of the resin pipes of the heat exchanger.

  The dehumidification rotor is supported by the circumferential wall portion of the cylindrical portion in a state where the dehumidification frame is supported by the dehumidification shaft through 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 an overhanging 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 limited particularly when the overhang portion is provided integrally with the tube portion within the range where the dehumidification rotor can be disposed within the tube portion, and when the overhang portion is not provided integrally with the tube portion. It is not a thing. However, if it extends beyond the dehumidifying frame to a position where it overlaps the water absorbent, the amount of air passing through the water absorbent is reduced, which is not preferable. In addition, the overhang | projection part should just be opposingly arranged with a dehumidification flame | frame, and may be provided in a heater, a communication path, a main fan unit, etc. in addition to a support member integrally or separately.

3. Support member (1) whole The support member should just support a dehumidification rotor at least, for example, does not need to support other units, such as a heater.
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 paying attention to 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 paying attention to 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.
When attention is paid to the structure of the lower guide space that guides 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, the receiver, and the upper cover, and the lower cover and the heat exchanger are not supported. Support is required.

(2) Stretched portion The support member has three stretched portions. However, as long as the dehumidification rotor can be supported, the stretched portion may be one, two, or four or more. . Considering the amount of air supplied to the dehumidification rotor, the number of stretched portions is preferably 4 or less.
In the embodiment, the receiver is brought into contact with the extended portion. However, when not paying attention to the attachment of the receiver, the receiver does not have to 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 both abut in the receiver.
The extending portion integrally including 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 stepped with respect to the resin pipe. In addition, this staircase shape also corresponds to an example of “having a plurality of teeth along the juxtaposed direction of the resin pipes”.

(3) Horizontal beam portion The horizontal beam portion integrally including 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 stepped with respect to the resin pipe. In addition, even when extending in such a direction that is not orthogonal, it corresponds to an example of “extending along the direction in which resin pipes are juxtaposed”.
In the embodiment, the extending portion having the comb portion and the horizontal beam portion are positioned on one straight line, but the horizontal beam portion and the extending portion may intersect like a “V”, for example. In this case, the teeth of the horizontal rail portion and the teeth of the extending portion can be implemented by providing a stepped shape as described above.
In the embodiment, the number of crosspieces is one. However, when the resin pipe is lengthened due to the size of the dehumidifier, the dehumidifying performance, etc., a plurality of crosspieces may be provided.

(4) Comb portion and teeth The comb portion of the embodiment is integrally provided in the extending portion and the horizontal beam portion, but may be mounted on the extending portion and the horizontal beam portion after being configured separately. When injection molding is performed using the resin material tail of the support member, 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 corners are rounded) that are long in the pipe axial direction of the resin pipe, but other shapes such as a square shape, a circular shape, an oval shape, etc. It may be. In consideration of the stress concentration 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, the extending | stretching front-end | tip part of a tooth | gear is more preferable to taper considering the arrangement | positioning 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, a heater is not connected to the support shaft. As the second shaft portion, a resin material having inferior heat resistance may be used, or the first shaft portion and the second shaft portion may be provided integrally with 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, a metal material can also be used as the second shaft portion, and for example, it can be integrated with the first shaft portion by insert molding.

(6) Tube portion The tube portion is recessed on the front side with reference to the first base portion of the base portion. For example, the tube portion may be recessed on the back side from the first base portion, The structure which dents into the front side and the back side from 1 base part may be sufficient.
The cylindrical portion has a cylindrical shape corresponding to the outer peripheral shape of the dehumidifying rotor, but it is sufficient that the dehumidifying rotor can rotate within the cylindrical portion. For example, the cylindrical portion may have a shape such as a square cylindrical portion. However, when the dehumidification rotor's dehumidifying frame is supported by 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 body The second shaft body 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. For example, a pin formed integrally with the connecting portion can be used. In the embodiment, the projecting portion of the second shaft body is fixed by a screw. However, when the projecting portion is fitted in the chipped portion of the first shaft portion, the second shaft is not fixed. The body never rotates. However, when the second shaft body rotates, a rotation load acts on the chipped portion via the protruding portion, and it is preferable to fix the protruding portion in consideration of durability.
Moreover, the 2nd shaft body should just have the axial part fixed coaxially with the 1st axial part, and another structure and fixing method may be sufficient as it. As another structure, a projecting portion projecting in two directions may be provided at one end of the shaft portion, and the projecting portion may be fixed by a screw or the like.

4).
