The liquid flows out of the evaporator 104 and further flows through the capillary to become a low-temperature and low-pressure refrigerant liquid and flow into the evaporator 101.

[0004] The refrigerant liquid in the evaporator 101 is heated by the sucked air 114 to evaporate, becomes low-pressure refrigerant gas, and is sucked into the compressor 113. At that time, the suction air 114 is simultaneously cooled by the evaporator 101, and moisture more than the saturated steam at the cooled temperature condenses, is received by the drain pan, and further falls into the tank 111 through the drain port,
Can be saved. As described above, the suction air 114 cooled by passing through the evaporator 101 and having a reduced absolute humidity passes through the condenser 104 and is further heated, passes through the ventilation duct 105 as room-temperature dry air, and passes through the ventilation fan 106.
Is discharged from the outlet 108 above.

Conventional example 2. In addition to the original purpose of dehumidifying the moisture in the air, the dehumidifier may be designed to blow dry air directly onto a humid object and dry it. There is a dehumidifier provided. FIG. 9 is a diagram showing a structure of a blow-out portion of a two-way blow-out dehumidifier disclosed in, for example, JP-A-5-141705. In the figure, 125 is a suction port, 136 is an evaporator, 138 is a condenser, 153 is a blower fan, 126

(A) to the first outlet 126, and FIG.
Is a wind direction guide plate for switching the air supply to the air outlet 127 of the air conditioner.

[0006] After the air from the front inlet 125 is dehumidified by the evaporator 136 and the condenser 138, the air from the blower fan 153 driven coaxially by a motor (not shown) is once collected upward in one direction, and the wind direction guide plate 162 As a result, the air is switched to the first outlet 126 or the second outlet 127 and exhausted.

Conventional example 3. FIG. 10 shows, for example, JP-A-8-1

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 An example of a dehumidifier capable of arbitrarily switching between low-noise blowing and high-efficiency and low-noise blowing in multiple directions and simultaneously blowing in multiple directions according to the present invention will be described with reference to the drawings. The configuration of the refrigeration cycle is the same as that of the prior art. 1 to 3 are views showing a dehumidifier according to Embodiment 1, FIG. 1 is a front external view of the dehumidifier, FIG. 2 is a side sectional view of the dehumidifier, and FIG. 3 is a front sectional view of the dehumidifier.

FIGS. 1 to 3 show an example of a blower.
Centering on a turbo fan 1 not using a scroll casing, a horizontally long upward air outlet 2 above the main body housing, a horizontally long downward air outlet 3 below, a vertically long left air outlet 4 leftward, and a rightward airflow. A vertically long rightward outlet 5 is provided.
Each air outlet is provided with a wind direction variable vane 6, 7, 8, 9 which is a lid for closing and closing the air direction.
Reference numeral 10 denotes a suction port provided in a suction grille 20 on the back of the unit on the back of the dehumidifier main body. An evaporator 11 and a condenser 12 are installed in an air passage 19 downstream of the suction port 10.

The water condensed in the evaporator 11 is supplied to the drain pan 1
The toner is received by the nozzle 8, passes through the drain port 13, and is stored in the tank 14. On the other hand, the evaporator 11 and the condenser 12 are connected to a compressor 16 mounted on the bottom plate 15 by a refrigerant pipe, and constitute a refrigerant circuit.

Next, the operation will be described. When the turbo fan 1 without the scroll casing operates and rotates, the suction flow into the turbo fan 1 is sucked from the suction port 10 on the back of the unit, passes through the evaporator 11 and the condenser 12 sequentially, and then the turbo fan 1 It leads to 1. The flow that has passed through the turbo fan 1 is radially blown out in the direction of rotation of the impeller, and each of the outlets having different longitudinal directions, an upward outlet 2, a downward outlet 3, a leftward outlet 4, a rightward outlet. 5 flows out as a blowing wind.

At this time, the outflow angles from the respective outlets are arbitrarily controlled by the wind direction variable vanes 6, 7, 8, 9 installed at the respective outlets. Variable wind direction vanes 6, 7, 8, 9
Can manually determine the position. Alternatively, the variable wind direction vanes 6, 7, 8, 9 are automatically controlled in accordance with the operation mode. At this time, the variable wind direction vanes 6, 7, 8, 9
When any one or more and three or less are closed, the air outlet is arbitrarily selected and the wind direction is controlled. Further, by controlling the opening and closing and the angles of the variable wind direction vanes 6, 7, 8, 9 in conjunction with each other, it is possible to simultaneously blow in any direction, and it is possible to set the air blowing mode widely.

Since the leftward outlet 4 and the rightward outlet 5 are vertically long, it is possible to create a vertically long airflow suitable for drying in a vertical space such as a press-in space and a space between a shoe box and furniture.

Further, since the upward air outlet 2 is horizontally long like the conventional dehumidifier, the same dehumidifier can create an airflow suitable for drying the laundry, and can use the vertically long airflow and the horizontally long airflow properly. .

Also, there are provided four outlets, an upward outlet 2, a downward outlet 3, a leftward outlet 4, and a rightward outlet 5, so that an arbitrary direction can be selected and blown out. For example, upper blowing horizontal airflow suitable for laundry drying, horizontal lower blowing airflow suitable for floor drying, side blowing vertical airflow suitable for closet and shoebox drying, and at least three types of airflow can be blown out.

Compared with the conventional dehumidifier, a margin is provided for the size of the scroll casing, the fan diameter and the compressor 16 can be increased, and the dehumidifying capacity can be increased. Also,
It is also possible to reduce the overall size of the unit by the amount of the scroll casing.

Further, since the turbo fan 1 is used, the motor efficiency is higher than that of a conventional dehumidifier using a sirocco fan or a cross flow fan. In addition, since the turbo fan 1 is used, the operation is stable even in an air passage having a large pressure loss as compared with a conventional sirocco fan or a cross flow fan, and a sudden deterioration of noise does not occur. Therefore,
Even when the restriction on the front area of the heat exchanger is the same as that of the conventional dehumidifier, it is possible to use a heat exchanger having a small distance between the fins or a heat exchanger having a large number of rows, thereby improving the dehumidifying ability.

Further, since the air outlets are provided on the upper, lower, left and right sides, the air blown from the turbo fan 1 can be blown out in various directions outside the unit without suddenly changing the angle, thereby improving the blowing efficiency. I do.
