An embodiment of the present invention will be described with reference to FIGS. In these figures, the same members as those of the conventional example are denoted by the same reference numerals. FIG. 2 is a schematic configuration diagram showing the first embodiment of the present invention.
[0024]
According to the figure, the indoor air is passed through the rotating body 2 passing through the first area 2a (which is an air passage for adsorbing the moisture of the indoor air to the moisture absorbing body (the rotating body 2)). It passes through the moisture absorption path 13 to be adsorbed by the moisture absorbent and the second region 2b (an air passage for heating the air in the regeneration path with a heater and releasing moisture from the moisture absorbent (rotary body 2) as heated air). And a regeneration path 14 for removing moisture from the moisture absorbing body by passing heated air through the rotating body 2 to be rotated. In the moisture absorbing path 13, the room passes between the radiation fins 3 a through the filter 7 and cools the condensation pipe 3 b. When the air comes into contact with the rotating body 2 passing through the first area 2a, moisture is deprived by the moisture absorbing body filled in the rotating body 2 and is sent out as dehumidified air into the room.
[0025]
In the regeneration path 14, the air heated by the heater 5 removes moisture from the moisture absorbing body in the rotating body 2 that is passing through the second area 2 b to regenerate the moisture absorbing body, and condenses the removed moisture in the condenser 3 to dehumidify. Is made. The condensed water is stored in the primary water storage tank 10 through the water inlet pipe 10a.
[0026]
A pump 9 and a water level detection device 26 are disposed in a primary water storage tank 10 formed by a closed tank through an upper wall, and a water inlet pipe 10a is connected to an end. A water supply pipe 11 is connected to the pump 9, and a water supply unit 11 a provided above the secondary water storage tank 8 is connected to a tip of the water supply pipe 11. The water supply unit 11a is a funnel container formed of resin, and is attached to the back surface of a door 22 provided on the dehumidifier body 1 so as to be openable and watertight.
[0027]
The water supply portion 11a is integrally formed with a nozzle 33 for supplying water to the secondary water storage tank 8 and a projection 34 for opening the closing valve 12 by pressing down the pressing portion 12a of the closing valve 12 provided on the upper lid 8a of the secondary water storage tank 8. Have been. The water pipe 11 is made of a soft resin pipe so that the door 22 can be freely opened and closed, and is disposed so as to be able to bend and respond to the fully opened state of the door 22 indicated by a dashed line and the closed state of the door 22 indicated by a solid line. ing.
[0028]
When the door 22 is in the closed state, the pressing portion 12a of the closing valve 12 is pressed by the protrusion 34, and the shielding member 12b is pressed down, so that a gap is formed between the closing portion 12c and the sealing portion 8c provided at the lower end of the water supply port 8b. The water dropped from the nozzle 33 of the water supply unit 11a is supplied to the secondary water storage tank 8 from the water supply port 8b.
[0029]
When the door 22 is opened upward, the projection 34 is retracted, and the shielding member 12b is raised by the urging force of the spring 16, comes into close contact with the sealing portion 8c, and does not leak from the water supply port 8b. Further, a door switch 30 that is turned on and off by opening and closing the door 22 is provided on the upper wall of the dehumidifier 1, and when the door 22 is opened, the pump 9 stops, water supply to the water supply unit 11 a stops, and It is designed to prevent water leakage.
[0030]
With the above configuration, the water condensed by the condenser 3 is stored in the primary water storage tank 10 through the water inlet pipe 10a, and the stored water is equal to or higher than the first predetermined water level (about 2 cm above the suction port of the pump 9). Is reached by the water level detecting device 26, the pump 9 is driven to pump out the stored water to the water supply unit 11a. The pumped water from the water supply unit 11a drops from the nozzle 33 onto the upper lid 8a of the secondary water storage tank 8, and is stored in the secondary water storage tank 8 from the water supply port 8b via the shielding member 12b. When the water level detecting device 26 detects that the water in the primary water storage tank 10 has been pumped out and reduced to the second predetermined water level (water level approximately 1 cm above the suction port of the pump 9), the pump 9 stops and the water is stored. Stop pumping until the first water level is reached.
[0031]
The above-described pumping operation is repeated to detect that the water in the secondary water storage tank 8 has reached a full level (a water level of about 80% of the capacity of the secondary water storage tank 8), such as a switch 36 shown in FIGS. When the means detects, the pump 9 is stopped. Then, the dehumidifying operation is performed in a state where the pump 9 is stopped, and the fact that the water stored in the primary water storage tank 10 has reached the third predetermined water level (about 1 cm below the back surface of the upper surface lid of the primary water storage tank 10). When the water level detection device 26 detects, the dehumidifying operation stops.
[0032]
When the door 22 is opened upward to take out the secondary water tank 8 that is full of water, the protruding part 34 is retracted, and the shielding member 12b is raised by the urging force of the spring 16 to come into close contact with the sealing part 8c, and during the removal. In addition, there is no need to worry about water overflowing from the secondary storage tank 8 during carrying. Then, when the secondary water storage tank 8 having been emptied of the water storage is set in the dehumidifier, the switch 36 (see FIG. 8) detects the setting of the empty secondary water storage tank 8 and drives the pump 9, and then the primary water storage tank is reached. When the water level detecting device 26 detects that the ten stored water has been pumped and reduced to the first predetermined water level, the dehumidifying operation is restarted.
[0033]
In the second embodiment, if the water inlet pipe 10a and the water pipe 11 are connected via the pump 9, the primary water storage tank 10 and the water level detecting device 26 can be eliminated. In that case, it is necessary to stop the dehumidifying operation when the detecting means detects that the water in the secondary water storage tank 8 has reached the full level. Further, if the shielding member 12b is constituted by a floating member having a specific gravity lower than that of water and floating on the water, the spring 16 can be eliminated, and when a handle 15 is provided on the upper part of the secondary water storage tank 8 as shown in FIG. It can be done easily.

When the micro switch 25c of the fall detection device 25 is turned off, the solenoid 40 of the door opening device 23 shown in FIG. 6 pushes the plunger 41 in the direction of arrow A1, and lowers the spindle 43 in the direction of arrow A2 via the lever. Then, the spindle 43 presses the upper lid 8a of the secondary water storage tank 8, opens the door 22 in the direction of arrow A3, and closes the closing valve 12. The arrangement of the solenoid 40 may be changed so that the plunger 41 directly presses the upper lid 8a of the secondary water storage tank 8. Reference numerals 44 and 45 denote compression springs for returning the lever 42 and the spindle 43 when the microswitch 25c is turned on.
[0037]
Further, it is desirable to stop the operation of the pump 9 when the micro switch 25c is turned off so that water does not leak from the water supply unit 11a. Further, at this time, the operation of the dehumidifier 1 is stopped so that the primary water storage tank 10 does not increase in water.
[0038]
Next, a fourth embodiment will be described with reference to FIG. In the figure, the secondary water storage tank 8 is placed on a tray 35, and a compression spring 50 and a switch 36 are installed below the tray 35.

It may be configured (fifth embodiment). In this way, when the empty secondary water storage tank 8 is placed on the tray 50, the switch 36a is turned on and the pump 9 can be operated, and the water storage in the secondary water storage tank 8 is almost full (for example, the secondary water storage tank 8). The switch 36b is turned on when the water level reaches about 70% of the capacity of the storage tank (not shown), and a full lamp (not shown) flashes and an alarm is sounded to urge the user to drain the secondary storage tank. The switch 36c detects that the water in the secondary water storage tank 8 has reached a full level (about 80% of the capacity of the secondary water storage tank 8) without drainage, and the operation is forcibly stopped.
[0040]
Next, a sixth embodiment will be described with reference to FIG. According to the figure, a door opening / closing detection device 20 for detecting the opening / closing of the door 22 is provided.

The detailed structure of the door opening / closing detecting device 20 is as shown in FIG. 11. When the door 22 is closed, the pressing portion 20a opens the closing valve 12, and the spindle 27 comes into contact with the upper lid 8a and is pushed up.
[0041]
Then, the lever 28 is moved rightward by the inclined surface 27a of the spindle 27, the micro switch 29 is turned on, and the pump 9 can be operated. When the door 22 is opened, the spindle 27 and the lever 28 are opened by the compression spring 31, the micro switch 29 is turned off, and the operation of the pump 9 is stopped. In this way, water does not leak from the water pipe 11 when the door 22 is opened.
[0042]
Next, a seventh embodiment will be described with reference to FIG. According to the figure, a packing 11b is provided in the water supply section 11a, and when the door 22 is closed, the space between the secondary water storage tank 8 and the upper lid 8a is sealed. Further, a water supply pipe 19 reaching the primary water storage tank 10 is provided in the water supply section 11a.
