(Embodiment 1)
An embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 and 2, the dehumidifying device of this embodiment includes a main body case 1 having an intake port 2 and an exhaust port 3, and a dehumidification rotor having a moisture absorbing portion 5 and a moisture releasing portion 6 in the main body case 1. 4 and a moisture absorption path 7.

  The moisture absorption path 7 includes a moisture release section 6 of the dehumidification rotor 4, a heater 8 which is a heating means provided on the windward side of the moisture release section 6, a regeneration chamber 9 provided on the leeward side of the moisture release section 6, A heat exchanger 10 provided on the leeward side of the regeneration chamber 9, and a second blower unit 11 provided on the leeward side of the heat exchanger 10 for circulating the air in the moisture absorption path 7. In this configuration, the moisture absorbing portion 5 of the dehumidifying rotor 4 is provided in the air passage between the first blowing means 14.

  More specifically, in FIG. 2, the main body case 1 has an intake port 2 on the back side and an exhaust port 3 on the upper side, and a tray 12 is provided below the front surface of the main body case 1 so as to be able to appear and retract. Yes. Further, a dehumidifying rotor 4 having a moisture absorbing part 5 and a moisture releasing part 6 is rotatably arranged in the main body case 1, and its rotational drive is performed by a motor 13 which is a driving means. .

  Further, in the front of the main body case 1, the indoor air sucked from the air inlet 2 of the main body case 1 passes through the hygroscopic portion 5 of the dehumidifying rotor 4 as in the first air passage shown by the arrow A in FIG. Thereafter, a first air blowing means 14 is provided for exhausting air from the exhaust port 3 to the outside of the main body case 1.

  The first air blowing means 14 is provided in the first casing 17 having a first suction port 15 on the back side, a first casing 17 having an upper first air outlet 16 shown in FIG. The first blade 18 and a first electric motor 19 that drives the first blade 18, and the room air that has passed through the moisture absorbing portion 5 of the dehumidifying rotor 4 is supplied from the first suction port 15 to the first air inlet 18. Flows into the casing 17, is pressurized by the first blade 18, and is exhausted out of the main body case via the first outlet 16 and the exhaust port 3.

  Further, a moisture absorption path 7 is provided in the main body case 1 as shown in FIG. 1, and the moisture absorption path 7 is provided on the moisture release portion 6 of the dehumidification rotor 4 and on the windward side of the moisture release portion 6. Heater 8 as a heating means, a regeneration chamber 9 provided on the leeward side of the moisture releasing section 6, a heat exchanger 10 provided on the leeward side of the regeneration chamber 9, and the air in the moisture absorption path 7 are circulated. And second air blowing means 11 to be operated. The moisture absorption path 7 is independent as a ventilation path in the main body case 1.

  Further, in the main body case 1, as indicated by an arrow B in FIG. 1, the indoor air sucked into the main body case 1 from the air inlet 2 by the first air blowing means 14 passes through the heat exchanger 10 of the moisture absorption path 7. Thereafter, an air passage for exhausting air from the exhaust port 3 to the outside of the main body case 1 is formed via the first air blowing means 14.

  However, the indoor air indicated by the arrow B is only exchanged with the air in the moisture absorption path 7 passing through the heat exchanger 10 through the heat conduction surface constituting the heat exchanger 10. There is no mixing in 10 parts.

  Here, the operation of the moisture absorption path 7 will be described. The air in the moisture absorption path 7 heated by the heater 8 is in the moisture release section 6 (this moisture release section 6 when the moisture absorption section 5 of the dehumidification rotor 4 rotates). Moisture is released, and this high-temperature and excessively humid air is sent to the heat exchanger 10 on the further leeward side through the regeneration chamber 9 provided on the leeward side.

  As described above, since the indoor air is blown to the heat exchanger 10 by the first blowing means 14 as shown by the arrow B, the high-temperature and excessively humid air is cooled, thereby condensing. It is stored in the tray 12.

  The moisture absorbing portion 5 of the dehumidifying rotor 4 adsorbs moisture every time indoor air passes as indicated by an arrow A, and this becomes the moisture releasing portion 6 described above by the rotation of the dehumidifying rotor 4 and becomes the moisture absorbing path 7. Moisture is released into the interior, and the indoor air is dehumidified by such circulation.

  The present embodiment is characterized in that the first temperature detection means 20 is provided between the regeneration chamber 9 and the heat exchanger 10 in the moisture absorption path 7, and the inlet 2 and the dehumidification rotor 4 in the first air passage are provided. A second temperature detection unit 21 is provided between the control unit 22 and the first temperature detection unit 20 or the second temperature detection unit 21 includes a control unit 22 that cuts off the power supply to the heater 8 when a predetermined set value is exceeded. This is a feature.

  Specifically, as shown in FIGS. 1 and 2, the first temperature detecting means 20 is located above the moisture absorption path 7 between the regeneration chamber 9 and the heat exchanger 10, and the circulation of the moisture absorption path 7 is performed. Detect the temperature of the air flow. The second temperature detection means 21 is located between the intake port 2 and the dehumidification rotor 4 and is in contact with the lower part of the regeneration chamber 9 to detect the temperature of the dehumidified air in the first air passage. When the temperature detected by the first temperature detection means 20 or the second temperature detection means 21 exceeds the temperature of a predetermined set value, the control unit 22 cuts off the power supply to the heater 8.

  That is, even in the closed state, the first temperature detection means 20 circulates and blows the same air volume in the moisture absorption path 7 as in the normal state, but detects the temperature of the circulating air.

  On the other hand, the second temperature detection means 21 detects the temperature of the dehumidified air that is dehumidified and exhausted into the room in the normal state, but this dehumidified air stays in the main body case 1 in the closed state. The temperature of the accumulated dehumidified air is detected.

  That is, since the dehumidified air that remains is generated only a slight flow of air, the temperature detected by the second temperature detection means 21 is higher than the temperature detected by the first temperature detection means 20 in the closed state. Since it becomes high temperature quickly, the temperature rise inside the main body case 1 in the closed state can be quickly detected. Thereby, safety can be further improved.

  Further, if the temperature of the set value of the first temperature detecting means 20 is simply lowered without providing the second temperature detecting means 21, the following problems may occur.

  That is, in a low humidity state where the indoor humidity is low, moisture is not sufficiently adsorbed to the dehumidifying rotor 4, and accordingly, moisture is not sufficiently diffused from the dehumidifying rotor 4, and the temperature in the moisture absorption path 7 is high. Therefore, there may be a problem that the control unit 22 interrupts the power supply to the heater 8 in spite of the normal state. Therefore, the first temperature detection means 20 is provided between the regeneration chamber 9 and the heat exchanger 10, and the second temperature detection means 21 is provided between the intake port 2 and the dehumidification rotor 4 in the first air passage. By providing, the said subject can be solved.

  In addition, the 1st temperature detection means 20 and the 2nd temperature detection means 21 are thermistors as an example. The set value of the second temperature detecting means 21 may be lower than the set value of the first temperature detecting means 20. That is, since it is located upstream of the dehumidification rotor 4 in the first air passage, the second temperature detection means 21 is not affected by the low humidity state in which the indoor humidity is low in the normal state. Even if the setting value of the second temperature detection means 21 is set lower than the setting value of the detection means 20, the above-mentioned problem that occurs in a low humidity state where the indoor humidity is low does not occur.

  That is, by setting the set value of the second temperature detecting means 21 to be lower than the set value of the first temperature detecting means 20, it is possible to detect the temperature rise inside the main body case 1 more quickly in the closed state. Can do.

  Further, the second temperature detection means 21 is configured on the downstream side in the rotation direction of the dehumidification rotor 4 of the regeneration chamber 9.

  Specifically, the dehumidifying rotor 4 has a disk-like shape having a rotation support portion 30 at the center, and adsorbs moisture in which a predetermined amount of a hygroscopic material mainly composed of Al 2 O 3 / SiO 2 is supported on the base material. It is an element to do. The dehumidifying rotor 4 is rotated by a motor 13. The dehumidifying section 6 of the dehumidifying rotor 4 is sandwiched between the heater 8 and the regeneration chamber 9. The regeneration chamber 9 has a substantially fan-shaped bowl shape and is positioned on the intake port 2 side on the back side of the main body case 1. That is, the main body case 1 is positioned above the main body case 1, and the dehumidifying rotor 4 is disposed on the windward side and the heat exchanger 10 is disposed on the leeward side. The second temperature detection means 21 is protected by a cylindrical tube, and is fixed to the regeneration chamber 9 on the downstream side in the rotation direction of the dehumidifying rotor 4. The dehumidifying rotor 4 rotates in the same direction as the clock hand as viewed from the air inlet 2.

  As a result, the dehumidification rotor 4 is rotated by the motor 13 while releasing moisture due to the heat from the heater 8, so that the dehumidification rotor 4 in an absolutely dry state is exposed on the downstream side in the rotation direction, and the cooling effect by the evaporation heat is exerted. Since it cannot be obtained, it has the effect of detecting the heat in the hottest region, and has the effect of promptly detecting the temperature rise inside the main body case 1.

  Further, the second temperature detection means 21 is configured in the central portion in the radial direction of the dehumidifying rotor 4 of the regeneration chamber 9. Specifically, it is mounted in a substantially fan-shaped substantially bowl shape so as to cover the moisture release portion 6 of the dehumidifying rotor 4. The second temperature detection means 21 is provided at the bottom of the regeneration chamber 9, that is, at the center of the surface of the regeneration chamber 9 extending obliquely upward from the center of rotation of the dehumidifying rotor 4.

  As a result, the temperature of the dehumidified air staying around the regeneration chamber 9 on the windward side of the dehumidification rotor 4 in the first air passage, the radiant heat from the dehumidification rotor 4, and the heat transmitted from the regeneration chamber 9 are detected, and the inside of the main body case 1 is detected. There is an effect that a temperature rise can be detected quickly. In addition, since high-temperature air tends to stay in the lower part of the bottom surface of the regeneration chamber 9, there is an effect that a temperature rise inside the main body case 1 can be detected more quickly.

  The second temperature detection means 21 is provided with a predetermined distance from the regeneration chamber 9. As described above, the second temperature detection means 21 can avoid the influence of the transfer heat of the regeneration chamber 9 at the time of low humidity by providing the distance from the regeneration chamber 9, so that the early disconnection of the low humidity state is avoided, and the closed state At times, the temperature rise inside the main body case 1 can be quickly detected.

  Specifically, the second temperature detection means 21 is configured to be fixed to a support portion 24 having a substantially U-shape extending from the regeneration chamber 9. The support 24 extends from the regeneration chamber 9 to the two legs 25 extending in the downstream direction in the rotational direction of the dehumidifying rotor 4, and extends from the tip of the one leg 25 to the tip of the other leg 25. And the mounting portion 26. The second temperature detection means 21 is attached to the attachment portion 26.

  That is, the second temperature detection means 21 has a predetermined distance from the regeneration chamber 9, and the second temperature detection means 21 further has a space portion 27 that is a space between the regeneration chamber 9. Therefore, the air flows into the space 27, the influence of heat transferred from the regeneration chamber 9 can be reduced, the premature disconnection of the low humidity state can be avoided, and the temperature rise inside the main body case 1 can be detected quickly in the closed state. Can do.

  Further, when the second temperature detecting means 21 exceeds a predetermined set value, the energization to the second air blowing means 11 is cut off after a certain time, and then the first air blowing means 14 and the motor 13 are turned on after a certain time. The control part 22 which interrupts | blocks electricity supply is provided.

  Thereby, the heat load downstream from the heater 8 of the second air passage can be reduced, and the inside of the main body case 1 can be cooled by blowing air to the first air passage for a certain period of time.

  In addition, the main body case 1 is provided with a display means, and the second temperature detection means 21 includes a control that turns off the LED 31 provided on the display means when a predetermined set value is exceeded and invalidates the operation by the operation unit 28. It is a thing.

  As a result, the damage can be prevented by promptly informing the customer.

  Further, the regeneration chamber 9 has a substantially fan shape and is provided with a chamber guide 29 for collecting condensed water in the regeneration chamber 9.

  Specifically, the chamber guide 29 has a hollow cylindrical shape, is positioned on the lower surface of the regeneration chamber 9, and extends from the lower surface of the regeneration chamber 9 to the upper portion of the dew condensation water tray 12. Thereby, the condensed water adhering to the reproduction | regeneration chamber 9 can be collect | recovered to the receiving tray 12 via the chamber guide 29, adhesion of the condensed water to the 2nd temperature detection means 21 can be suppressed, and the accuracy of temperature detection is improved. Can do.
