Description

[Technical field]

[0001] The present invention relates to a dehumidifier that dries clothes and dehumidifies indoor air, and has a configuration in which moisture is absorbed by a dehumidifying rotor carrying a moisture absorbent and the absorbed moisture is collected as condensed water. [Background technology]

[0002] Dehumidifiers that recover moisture absorbed by the dehumidifying rotor as condensed water include those that heat the moisture absorbed by the dehumidifying rotor in a heater and release it into high-temperature regenerated air, cool the high-humidity regenerated air containing the released moisture in a condenser to recover the condensed water, and return the regenerated air from which moisture has been removed to the heater and circulate it. In this regenerated air circulation type configuration, the high-humidity regenerated air is not discharged outside the device, and the condensation heat obtained when recovering moisture from the regenerated air can also be utilized, so that a dehumidifier having the characteristic of being able to quickly dry clothes, etc. is known. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2012-192330 A Summary of the Invention [Problem to be solved by the invention]

[0004] The problem with such conventional dehumidifiers is that the condensed water generated in the condenser and the condensed water that condenses in the air duct through which the regeneration air circulates turn into droplets and accumulate in the circulating air duct. Furthermore, some of the condensed water that condenses in the regeneration chamber leaks onto the dehumidification rotor and is re-adsorbed by the dehumidification rotor, which reduces the moisture absorption efficiency.

[0005] In other words, in order to quickly guide the water droplets that had accumulated in the regeneration chamber to the water storage section, a water drain pipe that communicated with the regeneration chamber was placed opposite the dehumidification rotor. However, this blocked the dehumidification air duct, which was a cause of a decrease in the moisture absorption efficiency of the dehumidification rotor.

[0006] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to make it possible to quickly guide water droplets generated in the circulation air duct to the water storage section without blocking the dehumidification air duct. [Means for solving the problem]

[0007] In order to achieve this object, the present invention provides a device that includes a main body case having an intake port and an exhaust port, a dehumidifying rotor provided within the main body case and having a moisture absorption region and a moisture release region, a motor for rotating the dehumidifying rotor, a water storage section provided below the dehumidifying rotor for storing water, a blower that exhausts air drawn in through the intake port of the main body case from the exhaust port to the outside of the main body case after passing through the moisture absorption region of the dehumidifying rotor via a dehumidifying air duct, and a circulation air duct provided within the main body case, the circulation air duct including the moisture release region of the dehumidifying rotor, a heating section provided upwind of the moisture release region, a regeneration chamber provided downwind of the moisture release region, and the The regeneration chamber has a heat exchanger provided on the downwind side of the regeneration chamber and a circulation blower that circulates air in the circulation air duct, the regeneration chamber being approximately box-shaped and having a first opening communicating with the moisture release area of ​​the dehumidification rotor, a second opening communicating with the heat exchanger, and a third opening opening downward, the third opening having a communication duct extending from the third opening, water condensed in the regeneration chamber passes through the communication duct from the third opening and accumulates in the water storage section, and the third opening and the communication duct are provided outside the outer periphery of the dehumidification rotor, thereby achieving the initial objective. Effect of the Invention

[0008] According to the present invention, a device for cooling a vehicle includes a main body case having an intake port and an exhaust port, a dehumidifying rotor provided within the main body case and having a moisture absorption region and a moisture release region, a motor for rotating the dehumidifying rotor, a water storage section provided below the dehumidifying rotor for storing water, a blower for exhausting air sucked from the intake port of the main body case to the outside of the main body case from the exhaust port after passing through the moisture absorption region of the dehumidifying rotor by a dehumidifying air duct, and a circulation air duct provided within the main body case, the circulation air duct including the moisture release region of the dehumidifying rotor, a heat generating section provided on the windward side of the moisture release region, and a regeneration chamber provided on the leeward side of the moisture release region. the regeneration chamber is generally box-shaped and has a first opening communicating with the moisture release area of ​​the dehumidification rotor, a second opening communicating with the heat exchanger, and a third opening opening downward, the third opening having a communication duct extending from the third opening, water condensed in the regeneration chamber flows from the third opening through the communication duct to accumulate in the water storage section, and the third opening and the communication duct are located outside the outer periphery of the dehumidification rotor.

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] (Embodiment 1) FIG. 1 is a perspective view of a dehumidifier in an embodiment of the present invention as viewed from the front side, FIG. 2 is a perspective view of the dehumidifier as viewed from the back side, FIG. 3 is an exploded perspective view showing the general configuration, FIG. 4 is a schematic cross-sectional view in a horizontal section, and FIG. 5 is a schematic view showing the inside of the dehumidifier.

[0013] As shown in Figures 1, 2, 3, 4, and 5, the dehumidifier of this embodiment has an intake port 2 on the front of a main body case 1 shaped like a vertically long box, an operation unit 3 on the top surface of the main body case 1, and an air outlet 4 on the upper rear side of the main body case 1. A user can operate the dehumidifier and check the operation mode by operating the operation unit 3. A freely rotatable louver 5 is provided above the air outlet 4. A water storage unit 6 is provided below the front side of the main body case 1 so as to be able to freely appear and disappear, and stores the dehumidified water generated within the main body case 1.

[0014] The main body case 1 contains a dehumidifying rotor section 7, a regeneration unit 8, and a blower 9.

[0015] The dehumidifying rotor unit 7 includes a dehumidifying rotor 10 , a support frame 11 , and a motor 12 .

[0016] The dehumidifying rotor 10 is disk-shaped and rotatably mounted on a support frame 11 so that the rotation axis extends horizontally. The dehumidifying rotor 10 is configured in a honeycomb shape that supports an adsorbent and allows ventilation in the axial direction. This adsorbent has the property that it can hold a lot of moisture if the relative humidity of the air it is exposed to is high, and the amount of moisture it can hold decreases as the relative humidity decreases. In this way, if the rotor is repeatedly contacted with multiple air streams with different relative humidities, moisture is adsorbed and desorbed according to the difference in the amount of moisture the adsorbent can hold at each relative humidity. The dehumidifying rotor has a moisture absorption area 10a that adsorbs moisture in the air to the dehumidifying rotor 10, and a moisture release area 10b that releases the moisture adsorbed to the dehumidifying rotor 10. The outer periphery of the dehumidifying rotor 10 has a large number of teeth 10c.

[0017] The support frame 11 is disposed so as to separate the front side and the back side of the main body case 1, and has a circular opening 11a in the center. The dehumidifying rotor 10 is disposed between the back side of the main body case 1 and the support frame 11, and is provided rotatably so as to close the opening 11a of the support frame 11.

[0018] Motor 12 is fixed to support frame 11 and has a gear (not shown) that comes into contact with a large number of teeth 10c protruding from the outer periphery of dehumidifying rotor 10. When motor 12 is driven, the gear rotates, which in turn rotates dehumidifying rotor 10.

[0019] The regeneration unit 8 has a circulation air duct 13 that communicates with one side (the front side of the main body case) of the moisture discharge area 10b in the dehumidifier rotor 10 and the other side (the rear side of the main body case) of the moisture discharge area 10b in the dehumidifier rotor 10, and a heat generating section 14, a heat exchanger 15, and a circulation blower 16 provided within the circulation air duct 13.

[0020] The heat generating section 14 is disposed on one side (the rear side of the main body case) of the moisture discharging area 10b of the dehumidifying rotor 10. The heat generating section 14 is made of a material that generates heat when electricity is applied thereto, such as a nichrome wire, and generates heat to cause moisture to be discharged from the dehumidifying rotor 10 in the moisture discharging area 10b of the dehumidifying rotor 10.

[0021] The heat exchanger 15 condenses the moisture by exchanging heat between the regeneration air containing moisture released from the moisture release region 10b of the dehumidification rotor 10 and the indoor air supplied by the blower 9. The heat exchanger 15 is disposed between the front surface of the main body case 1 and the support frame 11 so as to be adjacent to the dehumidification rotor 10 in the horizontal direction.

[0022] The circulation fan 16 is configured as a so-called sirocco fan that combines a motor 16a and an impeller 16b, and circulates air in the circulation air passage 13. The circulation fan 16 is disposed between the heat generating unit 14 and the heat exchanger 15 in the circulation air passage 13. The air blown from the circulation fan 16 passes through the heat generating unit 14, the moisture releasing region 10b of the dehumidifying rotor 10, and the heat exchanger 15 in this order, before being sucked into the circulation fan 16.

[0023] The blower 9 is disposed between the rear surface of the main body case 1 and the support frame 11. The blower 9 includes a motor unit 9a, a fan unit 9b rotated by the motor unit 9a, and a scroll-shaped casing unit 9c surrounding them.

[0024] The motor portion 9a is fixed to the casing portion 9c.

[0025] The fan unit 9b is a sirocco fan, and is fixed to a rotating shaft (not shown) that extends horizontally from the motor unit 9a. The rotating shaft of the motor unit 9a extends from the front side to the rear side of the main body case 1.

[0026] The casing portion 9c is provided with a discharge port 17 and an intake port 18. The discharge port 17 is provided on the upper surface side of the main body case 1 of the casing portion 9c. The intake port 18 is provided on the front surface side of the main body case 1 of the casing portion 9c. The casing portion 9c has a suction surface portion 19 to which the motor portion 9a is fixed and in which the intake port 18 is provided, a suction opposing surface portion 20 opposed to the suction surface portion 19, and a scroll-shaped scroll surface portion 21 connecting the suction surface portion 19 and the suction opposing surface portion 20. When the fan portion 9b is rotated by the motor portion 9a, air is sucked into the casing portion 9c from the intake port 18 of the casing portion 9c, and the sucked air is blown out of the casing portion 9c from the discharge port 17.

[0027] The main body case has a dehumidifying air passage 22 and a cooling air passage 23 therein.

[0028] The dehumidification air passage 22 is an air passage that communicates between the suction port 2 of the main body case 1, the moisture absorption region 10a of the dehumidification rotor 10, and the blower 9. Moisture in the air sucked in through the suction port 2 of the main body case 1 is adsorbed by the dehumidification rotor 10 in the moisture absorption region 10a of the dehumidification rotor 10 and dehumidified.

[0029] Cooling air passage 23 is an air passage that communicates between suction port 2 of main body case 1, heat exchanger 15, and blower 9. Heat exchanger 15 is cooled by air sucked in from suction port 2 of main body case 1. The air that has passed through dehumidification air passage 22 and cooling air passage 23 is mixed in blower 9 and blown out of the main body case from air outlet 4.

[0030] The dehumidification operation in the above configuration will be described. The blower 9 draws in indoor air from the inlet 2, causes moisture to be absorbed in the moisture absorption area 10a of the dehumidifier rotor 10, and the dehumidified air is blown into the room as dry air from the outlet 4 (dehumidifier air duct). The moisture absorbed by the dehumidifier rotor 10 moves to the moisture release area 10b by the rotational drive of the dehumidifier rotor 10, and is released to the circulation air duct 13 by heating of the heat generating unit 14. In the circulation air duct 13, the hot and humid air discharged from the moisture release area 10b of the dehumidifier rotor 10 is blown to the heat exchanger 15 by the blowing of the circulation blower 16. In the heat exchanger 15, heat is exchanged between the circulation air duct 13 and the cooling air duct 23 that was drawn into the main body case 1 by the blower 9 and cools the heat exchanger 15, and the hot and humid air in the circulation air duct 13 is cooled, moisture is condensed, and the air is collected in the water storage unit 6 as condensed water. The air in cooling air passage 23, whose temperature has increased after cooling heat exchanger 15, is mixed with the air in dehumidification air passage 22 by blower 9 and is blown into the room from air outlet 4. In this manner, the indoor air is dehumidified.

[0031] Fig. 6 is a perspective view showing a support frame, a regeneration chamber, and a communication duct of a dehumidifier according to an embodiment of the present invention. Fig. 7 is an exploded perspective view of the regeneration chamber of the dehumidifier as viewed from the windward side, and Fig. 8 is an exploded perspective view of the regeneration chamber of the dehumidifier as viewed from the leeward side.

[0032] As shown in Figs. 3 to 8, a regeneration chamber 29 is disposed downstream of the moisture discharging region 10b of the dehumidifying rotor 10 in the circulation air passage 13. The regeneration chamber 29 is an air passage surrounded by an upwind chamber 29a and a downwind chamber 29b. The regeneration chamber 29 is substantially box-shaped and has a first opening 30 communicating with the moisture discharging region 10b of the dehumidifying rotor 10 and a second opening 31 communicating with the heat exchanger 15. The air blown from the circulation blower 16 enters the regeneration chamber 29 through the heat generating section 14, the moisture discharging region 10b of the dehumidifying rotor 10, and the first opening 30 in this order. The air that has entered the regeneration chamber 29 is then sucked into the circulation blower 16 through the second opening 31 and the heat exchanger 15 in this order. The air that has entered the regeneration chamber 29 condenses in the regeneration chamber 29. Here, the regeneration chamber 29 has a third opening 32 that opens downward, and a communication duct 34 that extends downward from the third opening 32 and connects the third opening 32 to the receiving tray 33, and the third opening 32 and the communication duct 34 are located outside the outer periphery of the dehumidification rotor 10.

[0033] That is, since the communication duct 34 that communicates the third opening 32 and the receiving tray 33 is provided, the condensed water that condenses in the regeneration chamber 29 flows into the third opening 32 and can be quickly guided through the communication duct 34 to the water storage section 6 via the receiving tray 33. In addition, by providing the third opening 32 and the communication duct 34 outside the outer periphery of the dehumidifying rotor 10, the condensed water that condenses in the regeneration chamber 29 can be guided to the water storage section 6 via the receiving tray 33 without blocking the dehumidifying air passage 22, thereby improving the moisture absorption efficiency of the dehumidifying rotor 10.

[0034] In addition, the third opening 32 is located below the rotation axis of the dehumidifying rotor 10, and the bottom surface 36 of the regeneration chamber 29 having the third opening 32 is inclined so that the third opening 32 is located at the lowest end. That is, the condensed water condensed in the regeneration chamber 29 passes through the bottom surface 36 of the regeneration chamber 29 having the third opening 32, which is an inclined surface, and is collected at the lowest point in the regeneration chamber 29, and flows from the third opening 32 through the communication duct 34 to the receiver 33. The water accumulated in the receiver 33 can be quickly guided to the water storage section 6 through the holes in the receiver, so that an increase in pressure loss in the circulation air passage 13 due to water droplets accumulated in the circulation air passage can be suppressed, and the cooling efficiency of the heat exchanger 15 is improved.

[0035] In addition, a partition plate portion 35 having a substantially sector-like shape as a vertical plane is provided in the regeneration chamber 29 so as to face the first opening 30 and the moisture releasing region 10b of the dehumidification rotor 10. The third opening portion 32, which is located at the lowest point of the lower part of the regeneration chamber 29, is located on the downwind side of the partition plate portion 35.

[0036] That is, the regeneration chamber 29 has a first opening 30 on the leeward side of the moisture release region 10b of the dehumidification rotor 10, and a partition plate portion 35 on the leeward side of the first opening 30. Furthermore, a third opening 32 communicating with the receiver 33 is located on the leeward side of the partition plate portion 35 at the bottom of the regeneration chamber 29. As a result, the air flow in the regeneration chamber 29 and the partition plate portion 35 prevent the condensed water condensed in the regeneration chamber 29 from leaking out to the dehumidification rotor 10 side, and the condensed water flows into the third opening 32, so that the condensed water is not re-adsorbed by the dehumidification rotor, improving the moisture absorption efficiency. [Industrial Applicability]

[0037] It is expected that this device will be used as a dehumidifier with high dehumidifying capacity for home and office use. [Explanation of symbols]
