Description

  The present invention relates to a dehumidifying apparatus for drying clothes and the like and dehumidifying indoor air, having a configuration in which moisture is absorbed by a dehumidifying rotor carrying a moisture absorbent and the absorbed moisture is recovered as condensed water.

  As a dehumidifier that collects moisture absorbed by the dehumidification rotor as condensed water, the moisture absorbed by the dehumidification rotor is heated by a heater and released to high-temperature regeneration air, and the high-humidity regeneration air containing the released moisture is discharged. There is a configuration that cools in the condenser and collects condensed water and returns the regenerated air from which moisture has been removed to the heater and circulates it. In this regenerative air circulation type configuration, high-humidity regenerated air is external to the device. In addition, a dehumidifying device characterized by being able to quickly dry clothes and the like is also known because the condensation heat obtained when recovering moisture from the regenerated air can be used.

In the air passage between the first air blowing means 14 and the moisture absorbing portion 5 of the dehumidifying rotor 4 and the heat exchanger 10 are provided.

  More specifically, in FIG. 2, an intake port 2 is opened on the back side of the main body case 1, and a detachable filter 15 is provided in the intake port 2. There is a mouth 3, below the front surface of the main body case 1, a heat exchanger 10 and a second blowing means 11 are connected to collect a condensate 12 and a drain tank 16 for draining the condensate at the bottom. Is detachably stored.

  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 blowing means 14 includes a fan casing 17 that blows upward, blades 18 provided in the fan casing 17, and an electric motor (not shown) that drives the blades 18, and the dehumidifying rotor 4. The room air after passing through the hygroscopic part 5 flows into the fan casing 17, is pressurized by the blades 18, and is exhausted out of the main body case 1 through the exhaust port 3.

  Further, as shown in FIGS. 3 and 4, a moisture absorption path 7 is provided in the main body case 1, and the moisture absorption path 7 includes a moisture release part 6 of the dehumidification rotor 4 and a wind of the moisture release part 6.

  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. 2, 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 the moisture releasing part 6 (the moisture absorbing part 5 of the dehumidifying rotor 4 rotates to become this moisture releasing part 6). Then, the moisture is released, and this high-temperature and high-humidity air is further sent to the heat exchanger 10 on the 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 high-humidity air is cooled, thereby condensing, and this is drained. It is stored in the tank 16.

  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.

  As shown in FIGS. 5 to 9, the feature of the present embodiment is that the regeneration chamber 9 has a substantially box shape, the first opening 20 that communicates with the moisture releasing portion 6 of the dehumidifying rotor 4, the heat exchanger 10, A second opening 21 that communicates and a third opening 22 that communicates with the tray 12 are provided, and a partition is formed in the regeneration chamber 9 so as to oppose the first opening 20 and the moisture release section 6 of the dehumidifying rotor 4. A plate portion 23 is provided, and the third opening portion 22 is a point located on the leeward side of the partition plate portion 23 below the regeneration chamber 9.

  Specifically, the regeneration chamber 9 is substantially box-shaped, and a first opening 20 that is a substantially fan-shaped opening communicating with the moisture release portion 6 of the dehumidification rotor 4 is provided on the side surface on the dehumidification rotor 4 side. The upper side surface of the heat exchanger 10 side is provided with a substantially square second opening 21 communicating with the heat exchanger 10, and the lower opening is provided with a third opening 22 communicating with the tray 12. Yes. In the regeneration chamber 9, a substantially fan-shaped partition plate portion 23 that is a vertical plane is provided so as to face the first opening 20 and the moisture releasing portion 6 of the dehumidifying rotor 4. The third opening 22 located at the lowest point at the bottom of the reproduction chamber 9 is located on the leeward side with respect to the partition plate 23.

  That is, the third opening 22 that communicates with the tray 12 is positioned on the leeward side of the partition plate 23 below the regeneration chamber 9, so that condensation occurs in the regeneration chamber 9 due to the flow of air in the regeneration chamber 9. The dew condensation water that has flowed into the third opening 22 without leaking from the boundary with the dehumidification rotor 4 can be quickly guided to the drain tank.

Specifically, an exposed portion 24 that is a part of the partition plate portion 23 is located between the intake port 2 that is the first air passage and the dehumidification rotor 4 so as to face the intake port 2. is there.

  That is, the indoor air sucked into the main body case 1 from the air inlet 2 by the first air blowing means 14 hits the exposed portion 24 and cools the partition plate portion 23 through the exposed portion 24. More condensed water can be generated, and this condensed water can be guided to the drain tank 16.

  A water receiving portion 25 is provided below the lower end portion of the exposed portion 24 of the partition plate portion 23, and the water receiving portion 25 is provided with a communication hole 26 communicating with the tray.

  That is, the water condensing at the exposed portion 24 by providing the exposed portion 24 that is a part of the partition plate portion 23 exposed to the first air passage and the lower portion of the lower end portion of the exposed portion 24, thereby providing water. Is collected at one end in the water receiving portion 25, flows into the receiving tray 12 through the drainage pipe 19 from the communication hole 26 communicating with the receiving tray 12, and can be promptly guided to the drain tank 16.

  That is, it is possible to prevent water condensed at the exposed portion 24 from being re-adsorbed by the dehumidifying rotor 4, thereby improving the moisture absorption efficiency.
