A main body case having an intake port and an exhaust port; a dehumidification rotor which is provided in the main body case and has a moisture absorption portion and a moisture release portion; a rotating means for rotating the dehumidification rotor; and the intake port of the main body case A first air blower that exhausts the air sucked from the exhaust passage after passing through the moisture absorbing portion of the dehumidifying rotor by the dehumidifying air passage, and a regenerative air passage provided in the main body case And the regeneration air path includes the moisture release part of the dehumidification rotor, heat generating means provided on the windward side of the moisture release part, and a heat exchanger provided on the leeward side of the moisture release part; A second blower that circulates air in the regeneration air passage, and the heat exchanger is located on the leeward side of the dehumidifying portion of the dehumidification rotor of the regeneration air passage, and the dehumidification portion The body case of the air passage Located in the air path between the air vent and the moisture absorption part of the dehumidification rotor, the heat generating means is opposed to the air inlet part for taking in air from the second blower and the moisture release part of the dehumidification rotor. a box body having an open face, and a lid for covering the open face of the box body, said box body of fan shape, on the one hand the surface of the radial side having said air inlet portion, the lid portion an air outlet for blowing air heated by the heating means is provided in, along with the provided the first heating portion to the said box body and the second heating section, the air in the second heat generating section is fan-shape An air inlet portion side peripheral portion which is a peripheral portion on the air inlet portion side of the outlet portion and a counter air inlet portion side peripheral portion which is a peripheral portion facing the air inlet portion side are arranged in a bellows shape, The first heat generating portion is not adjacent to the air inlet side peripheral edge and the counter air inlet side peripheral edge. First air blown in the box that is arranged inside the air outlet part and flows to the air outlet part via the air inlet part, the first heat generating part, and the second heat generating part by the second blower A second box air passage that flows to the air outlet portion through the air inlet portion and the second heat generating portion, and the second box air passage passage is provided on the air outlet portion. Since at least a part of the peripheral portion flows, the pressure loss of the dehumidifying rotor is high, and thus air easily leaks, and at least a part of the peripheral portion of the air outlet portion of the lid portion includes the second heat generating portion. Since the second air flow path in the box that is heated only by heating is located, the amount of leakage of heated air from the air flow path in the first box that is heated by both the first heat generating part and the second heat generating part There is an effect that can be suppressed.

The second box air passage is opposed to the air inlet portion side peripheral portion which is the peripheral portion on the air inlet portion side of the air outlet portion and the peripheral portion facing the air inlet portion side of the air outlet portion. The area of the second heat generating portion of the second air passage in the second box located on the air inlet side peripheral edge is the second area of the counter air inlet side peripheral edge. Since the heating air supplied to the dehumidifying rotor is larger than the area of the second heat generating portion of the air passage in the box, the air outlet is on the air inlet side, so the air speed is fastest and the air outlet is likely to leak in a large amount other than the dehumidifying rotor. Since the heating amount of the dehumidification rotor can be relatively reduced at the peripheral portion on the air inlet side of the part, heat loss due to leakage of heated air can be reduced, and loss of moisture release performance of the dehumidification rotor can be reduced. There is an effect that can be done.

The second box air passage is opposed to the air inlet portion side peripheral portion which is the peripheral portion on the air inlet portion side of the air outlet portion and the peripheral portion facing the air inlet portion side of the air outlet portion. The rotation direction of the dehumidifying rotor is located in the air inlet portion side peripheral edge portion and rotates from the counter air inlet portion side peripheral edge portion to the air inlet portion side peripheral edge portion, and the counter air inlet portion side peripheral edge portion Since the area of the second heat generating portion of the second air passage in the box is larger than the area of the second heat generating portion of the second air passage on the air inlet side, the rotating dehumidification rotor When the first heat generating portion and the second heat generating portion are sufficiently heated by the second box air passage that is heated only by the second heat generating portion when moving from the moisture absorbing portion to the moisture releasing portion having the heat generating means. Since it shifts to the heating of the 1st box body air passage which performs heating by, the above-mentioned dehumidification rotor is Since there be heated to stimulation, an effect that can prevent cracking of the dehumidifying rotor due to thermal shock.

  Moreover, you may make it the structure that the emitted-heat amount of a 1st heat generating part is larger than a 2nd heat-generating part. As a result, the dehumidification rotor is intensively increased at the center line portion that is difficult to leak, compared to the peripheral edge portion on the air inlet portion side and the counter air inlet portion side that is likely to leak other than the dehumidification rotor. This has the effect of further increasing the efficiency of water release.

  Moreover, you may make it the structure that the emitted-heat amount of a 1st heat generating part is smaller than a 2nd heat-generating part. Accordingly, the first dehumidifying rotor in the moisture releasing section is heated by the first heat generating section and the second heat generating section from the second box air blowing path heated only by the second heat generating section. Since the heating amount of the dehumidification rotor is gradually increased when shifting to the above, the effect of reducing the deterioration of the dehumidification rotor element due to heating is exhibited.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, a main body case 1 having an intake port 4 and an exhaust port 6, a dehumidifying rotor 2 having a moisture absorbing portion 2 b and a moisture releasing portion 2 a in the main body case 1, and the dehumidifying rotor 2 are rotated. The rotating means 3 to be moved and the first blower 7 are provided. This first blower 7 blows air to the dehumidifying air passage b. The dehumidifying air passage b has a configuration in which an intake port 4, a heat exchanger 5 to be described later, a moisture absorbing portion 2 b of the dehumidifying rotor 2, and an exhaust port 6 are sequentially provided. That is, the air sucked from the air inlet 4 is passed through the moisture absorbing portion 2b of the dehumidifying rotor 2 through the outer surface of the heat exchanger 5 described later, thereby allowing the air sucked from the air inlet 4 to be absorbed. The air is adsorbed, that is, dehumidified by the moisture absorbing portion 2 b of the dehumidifying rotor 2, and the dehumidified air is exhausted out of the main body case 1 through the exhaust port 6.

That is, first, the air in the regeneration air passage a is heated by the heat generating means 9 to be in a high temperature and low relative humidity state, and blown to the moisture releasing portion 2 a of the dehumidifying rotor 2. Here, since the air at a high temperature and a low relative humidity passes through the moisture releasing portion 2a of the dehumidifying rotor 2, the moisture of the moisture releasing portion 2a of the dehumidifying rotor 2 is released to this air. Next, the air containing the moisture and having a high relative humidity is blown into the heat exchanger 5. Here, the heat exchanger 5 is located in the dehumidifying air passage b, and has a regeneration air passage a inside the heat exchanger 5. That is, in the heat exchanger 5, air having high relative humidity including moisture is blown from the moisture release portion 2 a of the dehumidifying rotor 2 through the regeneration air passage a, and is also formed on the outer surface of the heat exchanger 5. The air sucked from the air inlet 4 of the main body case 1 is blown through the dehumidifying air passage b. That is, air having high relative humidity including moisture in the regeneration air passage a, that is, in the heat exchanger 5 passes through the heat exchanger 5 through the dehumidification air passage b, that is, the outer surface of the heat exchanger 5. It is cooled by the air sucked from the air inlet 4 of the main body case 1 to be dehumidified as a result. Then, the dehumidified air is again blown to the heat generating means 9 and circulated.

  As shown in FIG. 2, the heat generating means 9 includes a substantially fan-shaped box 10 having an air inlet portion 11 and an opening surface, a substantially fan-shaped lid 12 covering the opening surface of the box 10, In the box 10, a first electric heating body 14 that is a first heat generating portion and a second electric heating body 15 that is a second heat generating portion are provided. The box 10 has an air inlet portion 11 for taking in air blown from the second blower 8 and an opening surface facing the moisture release portion 2 a of the dehumidifying rotor 2. The lid 12 is provided with a substantially fan-shaped air outlet 13 for blowing out the air heated by the heat generating means 9.

  As shown in FIG. 3, the first electric heating body 14 and the second electric heating body 15 are supported by a plurality of insulating plates 16 that are perpendicular to the air outlet portion 13 and radially arranged. In contrast, two layers are stacked in the vertical direction. The one near the air outlet 13 is the second electric heating element 15, and the one far from the air outlet 13 is the first electric heating element 14.

  As shown in FIG. 4, the second electric heating element 15 includes an air inlet portion side peripheral portion 17 that is a peripheral portion on the air inlet portion 11 side of the substantially fan-shaped air outlet portion 13, and a peripheral portion that faces the air inlet portion 11 side. The first electric heating element 14 is not adjacent to the air inlet part side peripheral part 17 and the counter air inlet part side peripheral part 18. Further, it is arranged inside the air outlet portion 13.

  That is, the heated air supplied from the air outlet portion 13 to the dehumidifying rotor 2 flows from the air outlet portion 13 to the dehumidifying rotor 2 via the first electric heater 14 and the second electric heater 15. Then, two second box air passages 20 that flow from the air outlet 13 to the dehumidifying rotor 2 only through the second electric heater are provided.

  Further, in the two second box air passages 20 at two locations, the heat generation area of the second box air passage 20 at the air inlet portion side peripheral edge portion 17 is the second box inside the counter air inlet portion side peripheral edge portion 18. The heat generation area of the air passage 20 is larger.

  Further, the amount of heat generated by the first electric heating element 14 is larger than that of the second electric heating element 15.

  Further, the rotation direction of the dehumidification rotor 2 is configured to rotate from the counter air inlet portion side peripheral portion 18 toward the air inlet portion side peripheral portion 17.

  According to such a configuration, since the pressure loss of the dehumidifying rotor 2 is high, the air speed is the fastest because of the air inlet portion 11 side, and the air outlet portion side of the air outlet portion 13 of the lid portion that is likely to leak in a large amount other than the dehumidifying rotor 2 Since the second box air passage 20 heated only by the second electric heating body 15 is located at the peripheral edge portion 17 and the heating amount of the dehumidification rotor 2 can be relatively reduced, the first electric heating body 14 and the second electric heating The amount of leakage of heated air from the first box air passage 19 heated by both of the bodies 15 can be suppressed, the heat loss due to the leakage of heated air is reduced, and the moisture release performance of the dehumidifying rotor 2 is lost. Can be reduced.

  In addition, since the amount of heat generated by the first electric heating element 14 is larger than that of the second electric heating element 15, by increasing the heating amount of the dehumidification rotor 2 intensively at the center line portion of the substantially fan-shaped air outlet portion 13 that is difficult to leak, The moisture release efficiency of the dehumidifying rotor 2 can be further increased.

  As shown in FIG. 5, in the two second box air passages 20 at two locations, the heat generation area of the second box air passage 20 at the air inlet portion side peripheral edge portion 17 is that of the counter air inlet portion side peripheral edge portion 18. The heat generation area of the second box air passage 20 is smaller.

  Further, the amount of heat generated by the first electric heater 14 is smaller than that of the second electric heater 15.

  According to such a configuration, when the rotating dehumidifying rotor 2 moves from the moisture absorbing portion 2b to the moisture releasing portion 2a having the heat generating means 9, the second box air passage for heating only by the second electric heating body 15 is used. After sufficient heating at 20, the process shifts to heating of the first box air passage 19 that is heated by the first electric heater 14 and the second electric heater 15, so that the dehumidification rotor 2 is heated rapidly. Therefore, the dehumidification rotor 2 can be prevented from cracking due to thermal shock.

  In addition, since the amount of heat generated by the first electric heating body 14 is smaller than that of the second electric heating body 15, the second dehumidification rotor 2 that is rotated only by the second electric heating body 15 in the moisture release section 2 a is used as the second box air passage 20. Since the amount of heating of the dehumidification rotor 2 is gradually increased when moving from the first electric heating body 14 to the first box air passage 19 heated by the first electric heating body 14 and the second electric heating body 15, the elements of the dehumidification rotor 2 due to heating are increased.

A small amount of air is supplied to the air inlet portion side peripheral portion 17 and the counter air inlet portion side peripheral portion 18 of the air outlet portion 13, and the amount of heating increases in proportion to the center portion of the air outlet portion 13. Since the difference in temperature of the dehumidification rotor 2 of the moisture release section 2a in the rotational direction 2 is reduced, the deterioration of the elements of the dehumidification rotor 2 due to heating can be further reduced.
