DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling device for a toilet provided with a refrigerant cycle.

[0002]

2. Description of the Related Art Conventionally, a cooling apparatus for a toilet has been disclosed in
There was a configuration as shown in JP-A-115632.
Hereinafter, the configuration will be described with reference to the drawings. As shown in FIG. 2, the refrigerant compressor 1, the condenser 2, the pressure reducing device 3
And a refrigerant cycle in which the evaporator 4 is sequentially connected, and radiates heat generated in the condenser 2 of the air conditioner to water in the rotary tank 6 that stores water flowing to the toilet 5 installed in the toilet. To cool the toilet.

[0003]

However, in the above-mentioned conventional construction, since the decompression device 3 is installed outside the rotary tank 6, the high-pressure refrigerant between the condenser 2 and the decompression device 3 after the operation is stopped is balanced by high and low pressure. Change to low pressure gas refrigerant. Therefore, the gas refrigerant flows into the decompression device 3 designed to optimally decompress the liquid refrigerant at the time of restart, and the pressure is reduced to a predetermined value or more. Even when the operation is started at the time of use, there is a disadvantage that it takes time for the cool air to blow out.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a cooling device for a toilet which can speed up the start-up of blowing cold air and improve the cooling capacity.

[0005]

In order to achieve the above object, the present invention comprises a refrigerant closed circuit in which a compressor, a condenser, a decompression device and an evaporator are sequentially connected. It has a configuration buried in a water tank.

[0006]

In the above configuration, since the condenser and the decompression device are buried in the water tank, the high-pressure liquid refrigerant flows through the decompression device when the operation is stopped. During this time, the liquid refrigerant remains as it is, and the low pressure side of the compressor does not drop abnormally. Therefore, even at the time of restart, the liquid refrigerant flows through the pressure reducing device, so that the blowing of the cool air can be accelerated.

[0007]

An embodiment of the present invention will be described below with reference to FIG. As shown in the figure, a cooling / heating unit 11 cools a refrigerant closed circuit in which a compressor 12, a condenser 13, a decompression device 14, and an evaporator 15 are sequentially connected, and a water tank 17 and an evaporator 15 provided on an upper part of a toilet bowl 16. Blower 1
8. It is composed of a heater 19 for heating the inside of the toilet. The condenser 13 and the pressure reducing device 14 are installed below the surface of the water tank 17.

[0008] The operation of the thus configured toilet cooling apparatus will be described below. That is,
The high-temperature, high-pressure gas refrigerant compressed by the compressor 12 flows to the condenser 13, radiates heat in the water tank 17, and is liquefied by the condensation action. Then, the pressure is reduced by the pressure reducing device 14 and flows into the evaporator 15, where it is vaporized and gasified and returns to the compressor 12. When the operation is stopped, the liquid refrigerant is supplied from the high pressure side condenser 13 to the pressure reducing device 1.
4 and flow to the low-pressure side evaporator 15 to balance the pressure. At this time, even when the apparatus is restarted, since the pressure reducing device 14 is cooled by the water in the water tank 17, the liquid refrigerant flows and is decompressed, and flows into the evaporator 15 at a predetermined pressure. With this configuration, the low-pressure side of the compressor 12 does not abnormally decrease, and the liquid refrigerant flows through the pressure reducing device 14 even at the time of restart, so that the blowing of the cool air can be sped up, and the cooling capacity can be improved. If the heater 19 is energized, heating can be performed.

[0009]

As is apparent from the above embodiment, the toilet cooling apparatus of the present invention includes a refrigerant closed circuit in which a compressor, a condenser, a decompression device, and an evaporator are sequentially connected. The device is buried in a water tank. With this configuration, it is possible to speed up the start-up of blowing the cool air and improve the cooling capacity.
