In this toilet air conditioner 101, the heat generated by the condenser 106 is radiated to the water in the raw tank 110. Therefore, the water temperature in the low tank 110 gradually rises, and as a result, the temperature difference between the condenser 106 and the water becomes small, so that the cooling capacity also gradually decreases.

[0006] Therefore, when the temperature sensor 114 in the raw tank 110 exceeds a set value, the drive unit 113 lifts the water shutoff valve 112 to raise the drainage port 11.
5 is opened, high temperature water is discharged from the low tank 110, and new water is supplied from the water supply device 111 to recover the cooling capacity.

[0007]

However, when the water temperature when draining the water in the low tank 110 is set to be high, the capacity of the condenser 106 decreases as the water temperature rises, so that stable cooling performance is obtained. I can't get it. Conversely, if the set temperature during drainage is lowered, the low tank 110
There is a lot of wasted water because it is necessary to replenish the water inside.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a toilet air conditioner in which a troublesome duct work is unnecessary and a stable cooling capacity can be obtained.

Exhausted naturally through the window.

In this case, if a detachable exhaust duct is provided at the air outlet, the air from which the heat generated in the condenser is recovered is blown out from a position higher than the heat outlet.

When the main body is formed in a vertically long shape having substantially right-angled corners and the corners are installed so as to face one corner of the toilet space, the installation space of the toilet air conditioner can be reduced. .

Further, if the condenser and the evaporator are vertically spaced apart from each other so that a space for storing the fragrance or the deodorant is formed in the external part of the main body, only the space is provided. The position of the heat radiation outlet on the upper surface of the main body becomes higher. A portable TV or a clock may be placed in the space. Even if a liquid crystal television or a clock is installed at a position where the external appearance of the main body can be easily seen, the usability is improved.

Further, in the toilet air conditioner of the present invention, a detachable drain tank for receiving and accommodating the dew attached to the evaporator and a water level in the drain tank above a predetermined level, And a float switch for stopping the operation of the refrigeration cycle. According to this, when the water level of the water accumulated in the drain tank reaches a certain level or more, the operation of the refrigeration cycle is automatically stopped.

Dew attached to the evaporator may be drained to the outside of the main body by a drain pipe. In this case, the drain tank is unnecessary.

Further, when the refrigeration cycle is stopped, by operating the blower, the toilet can be ventilated when it is not in use.
