BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for efficiently air-conditioning a closed room having a relatively small volume in a toilet room.

[0002]

2. Description of the Related Art Conventionally, the toilet is air-conditioned in the same manner as other living rooms, offices, etc.
Or, in the current public toilets, etc., ventilation is performed but air conditioning is not performed at all.

[0003]

In the case of air-conditioning the entire toilet, if the toilet room area is large, most of it becomes useless air-conditioning, which is uneconomical. An object of the present invention is to efficiently perform air conditioning while performing ventilation in a closed room with a small volume such as a toilet.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and cools a condenser with air above the ceiling and discharges its exhaust heat directly to the outside of a closed room such as a toilet. An air conditioner is installed behind the ceiling, and an air outlet is provided to blow a part of the air above the ceiling through the evaporator of the air conditioner to the indoor side, and the room air is ceilinged on the ceiling surface that separates the room from the inside of the ceiling. The gist is that an opening for leading to the back and an opening for absorbing outside air in the ceiling are provided on the outer wall.

[0005]

[Function] An air conditioner is installed on the ceiling above the toilet, the condenser is cooled by the air above the ceiling, and the exhaust heat is directly exhausted to the outside. Also, a part of the air above the ceiling is used to vaporize the condenser. The wind that passed through is returned to the room. Also, at the same time when the air in the toilet room is returned to the ceiling from the opening above the ceiling, an opening is provided to the outside of the ceiling so that outside air can be taken in from the outside, and this opening is adjusted so that the toilet room has a negative pressure. Therefore, even in a closed room with a relatively small volume such as a toilet, it is possible to perform efficient air conditioning while ventilating, and by using a heat pump type air conditioner, a cooling and heating operation can be performed with a switch.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to illustrated embodiments. In the figure, 1 is a closed room with a relatively small volume such as a toilet (hereinafter abbreviated as a toilet), and an air conditioner 4 having a required capacity is installed behind this ceiling 2, that is, inside the ceiling 3 such as a toilet. The air conditioner 4 is of a type including a condenser 6 and an evaporator 5, and the condenser 6 and the evaporator 5 are respectively arranged in chambers partitioned by a partition plate 7 and the chambers are separated from each other. Are equipped with dedicated blowers 8 and 9 respectively so as to be able to suck the air in the attic 3 and a part of the air in the attic is introduced into the room R1 via the condenser 4 to exchange heat with the condenser 4. After that, the air is exhausted to the outside of the room by the exhaust port 10 provided on the outer wall of the blower 8, and when a part of the ceiling is ventilated through the evaporator 5, the heat is exchanged as desired and guided to the room R2, and then to the blower 9. Blow it out into the room R such as a toilet.

Further, an intake port 12 for taking outside air into the ceiling 3 is opened in the outer wall 11, and an exhaust port 13 for exhausting air in the room R such as a toilet to the ceiling 3 in the ceiling 2.
Is opened. Therefore, according to the present invention, the air conditioner 4 is arranged behind the ceiling of a toilet or the like, and on the cooling side, the outside air entering from the outside air inlet 12 and the air returning from the ceiling surface inlet 13 attached to the toilet ceiling surface. Is sucked in, cooled, and blown out from the ceiling surface outlet 9 to cool the toilet room.

Similar to the cooling side, the exhaust heat side sucks in the outside air and the air returning from the inside of the toilet and discharges it to the outside air. Further, the outside air suction port 12 uses a suction port with a damper so that the outside air suction port 12 can be adjusted so that more air is exhausted than the outside air entering from the outside air suction port 12 for ventilating the toilet air. The air conditioner is operated in conjunction with the toilet light switch. Shutdown will be delayed from the switch OFF to ventilate the room, and an electric circuit will be installed to automatically stop.

[0009]

[Effect of the Invention] According to the present invention, the air inside the room is circulated between the room and the ceiling via the outlet of the evaporator / blower, and the exhaust heat of the condenser is directly discharged from the ceiling to the outside. Since the air passages passing through the evaporator and the condenser are independently configured as described above, it is possible to efficiently air-condition even in a closed room and suck the outside air into the toilet room and into the ceiling. Since it is used for ventilation, it has an advantage that ventilation can be performed at the same time.
