Reference numeral 1 denotes an evaporator provided in an air passage downstream of a suction port 2 provided on the back of a main body A. A condenser 3 is provided downstream, and an air outlet 8 having a wind direction variable louver 6 is further provided downstream through a blower duct 4, a blower fan 5, and a blowout duct 7. Evaporator 1 and condenser 3
Is fixed by a ventilation plate 4 and a drain plate 11 having a drain port 10 formed therein. Reference numeral 13 denotes a tank installed below the drain port 8. Reference numeral 12 denotes a compressor, and the evaporator 1
And the condenser 3 are connected by a refrigerant pipe 14 to form a refrigerant circuit. Reference numeral 22 denotes a control board for controlling the operation of the dehumidifier.

Next, the operation will be described. When an operation switch (not shown) is turned on, the compressor 12 is energized, and a high-temperature and high-pressure refrigerant gas flows into the condenser 3, and the condenser 3 is kept at a high temperature. In addition, the blower fan 5 is also energized, and the refrigerant gas in the condenser 3 is cooled and condensed by the suction air 9 sucked in from the suction port 2 to be in a high-temperature and high-pressure gas-liquid mixed state. , It becomes a low-temperature low-pressure refrigerant liquid and enters the evaporator 1.

[0004] The refrigerant liquid in the evaporator 1 is heated by the sucked air, evaporates and becomes low-pressure refrigerant gas, and the compressor 12
Inhaled. At this time, the suction air 9 is simultaneously cooled by the evaporator 1, and the moisture contained in the cooled steam at a temperature higher than the saturated water vapor is condensed and received by the drain plate 11, and falls into the tank 13 from the drain port 10 and is stored. Can be

As described above, the intake air 9 is cooled by passing through the evaporator 1, and the absolute humidity is reduced.
Further, the air is heated by passing through the condenser 3, passed through the air duct 4 as the dry air heated from the time of suction, and is sent to the air outlet 8 by the air blow fan 5 through the air outlet duct 7. The air is bent in the rear direction and is discharged as blown air 21.

[0006] In general, a dehumidifier is sometimes used for drying moist objects such as laundry in addition to the original purpose of dehumidifying moisture in the air. In this case, if the dried air is directly applied to the target, the drying speed of the target can be further increased. Therefore, it is important to change the air blown from the outlet 8 so that the air can be sent over a wider range. For this reason, the wind direction variable louver 6 is provided so that the direction of the blown air can be arbitrarily changed within a certain range.

As another conventional example, there is a dehumidifier provided with two air outlets. FIG. 7 is a sectional view of a main part of a dehumidifier having two air outlets disclosed in Japanese Patent Application Laid-Open No. Hei 5-141705. In the figure, 105 is an inlet, 106 is a first outlet, 107 is a second outlet, 136 is an evaporator, 138 is a condenser, 153 is a blower fan, and 162 is the first outlet 106 in FIG. In FIG. 7B, the louver is a wind direction variable louver that switches the air blowing to the second outlet 107. In such a dehumidifier, after the air sucked from the inlet 105 on the front face is dehumidified by the evaporator 136 and the condenser 138,
The louver 162 passes through the blower fan 153,
It is blown out from either the first outlet 106 or the second outlet 107.

[0008]

However, in the former conventional example, only one air outlet 8 is provided in the upper front part of the main body A, so that the blown air 12 is directed in the direction from the upper surface to the rear surface. Or it could only blow out from the top to the front. Further, since the latter conventional example has the first air outlet 106 and the second air outlet 107, it is possible to blow dry air toward the front, top, and back of the main body. Since the first outlet 106 in the direction is oriented above the main body and in the horizontal direction,
Sufficient effects were not obtained for drying floors, tatami mats, carpets, etc. and drying futons, and the range of use was narrow.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is possible to set a wide blowing direction of dry air, and it is possible to dry laundry by an upper blowing and a floor by a lower blowing. It is an object of the present invention to provide a dehumidifier that can add utility value to new uses such as drying of a surface, a tatami mat, a carpet, and the like, and drying of a futon, and has a wide use range.
