Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a unit bath system equipped with an air conditioner for living rooms.

(Prior Art) In unit baths, heat and water vapor contained in the air within the bathroom are generally exhausted to the outside through vents. On the other hand, air conditioners for living rooms are required to take measures to prevent the humidity in the living room from decreasing, especially during heating, but so far no air conditioner has been found that utilizes heat or water vapor in the bathroom. Furthermore, no equipment was found that combined a unit bath and an air conditioner for a living room.

(Problem to be solved by the invention) The air in the bathroom is warm and highly humid, and it would be wasteful for this air to be discharged outside without being used for other purposes. Furthermore, the upper part of the unit bath generally has a large space and is used as an exhaust route, but this space has not been used effectively for other purposes.

An object of the present invention is to provide a unit bath system with an air conditioner, in which the air conditioner is disposed above the unit bath, and the air in the bathroom can be used to air condition the living room.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a unit bath having a vent at the top of the bathroom, with a room air inlet and an air outlet for air conditioning in the room above the bathroom. a heat exchanger disposed between an inlet and the air outlet; the vent is an air inlet together with the room air inlet; An air conditioner equipped with a damper capable of opening and closing the ventilation port and the room air intake port was installed, and the drain pipe of the air conditioner was connected to the drain pipe of the unit bath.

(Function) According to the present invention, when the air conditioner is operated for heating using the vent as an air intake port, air containing heat and water vapor in the bathroom is supplied to the air conditioner, and the air is exchanged with air. Air is supplied to the living room from the air outlet. Similarly, when the air conditioner is operated for ventilation, air from the bathroom is supplied to the living room. The drain from the air conditioner is then discharged through the unit bath drain pipe.

(Embodiment) FIG. 1 is a block diagram of a unit bath system with an air conditioner showing an embodiment of the present invention.

In the figure, 1 is a unit bath, 2 is its bathroom, 3 is a bathtub, 4 is a drain pipe of unit bath 1, and 5 is a bathtub.
is a vent provided at the top of the unit bath 1.

Reference numeral 6 denotes an indoor air conditioning unit of the air conditioner, which is composed of an indoor heat exchanger 7 and a blower 8, is arranged above the unit bath 1, takes in air from the ventilation port 5 of the unit bath 1 or the room air intake port 9, and is connected to the heat exchanger. 7 exchanges heat and the air is sent to an air outlet 10 for room air conditioning.
Supplied to the living room. 11 is a top plate that forms an air passage for air conditioning. Reference numeral 12 denotes a damper that opens and closes the ventilation port 5 and the room air intake port 9, and is formed so that the room air intake port 9 closes as the ventilation port 5 opens. A drain pipe 13 is connected to the drain pipe 4 of the unit bath 1 and discharges the drain from the indoor heat exchanger 7.

Reference numeral 14 denotes an outdoor air conditioning unit of the air conditioner, which is composed of a compressor 15, an outdoor heat exchanger 16, a blower 17, a four-way valve 18, an expansion valve 19, etc., and is connected to each other and to the indoor air conditioning unit 6 by a refrigerant pipe 20. connected.

Next, the operation of the unit bus system with air conditioner having the above configuration will be explained.

When performing heating operation, the four-way valve 18 is set to the switching position shown by the solid line in FIG. 1, and when the compressor 15 is operated, the compressed refrigerant whose temperature has increased circulates through the indoor heat exchanger 7 as shown by the solid line arrow. . Then, when the vent 5 is opened by the damper 12 as shown by the solid line in the figure, the air in the bathroom 2 is transferred to the blower 8.
The air is sucked in by the air, heat exchanged by the indoor heat exchanger 7, and then supplied to the living room from the air outlet 10. Since the air in the bathroom 2 is highly humid and warm, the humidity in the living room is improved and heating efficiency is also improved.

When performing the next ventilation operation, the compressor 15 is stopped and the blower 8 is operated. and vent 5
When the bathroom 2 is opened in the same way, the air in the bathroom 2 is supplied to the living room, and the living room is humidified and heated.

During cooling operation, the four-way valve 18 is switched as shown by the broken line in the figure, and when the compressor 15 is operated, the cooled refrigerant passes through the expansion valve 19 and flows through the indoor heat exchanger 7 as shown by the broken line arrow. circulate.
In this case, the vent 5 is closed by the damper 12 as shown by the broken line in the figure, and the room air intake port 9 is opened to circulate the air in the room. The air is heat exchanged by the indoor heat exchanger 7 to cool the living room.

When heating or cooling the bathroom 2, the vent 5 is opened by the damper 12, the blower 8 is reversely rotated, the four-way valve 18 is set to the heating or cooling state, and the compressor 15 is operated. Air is taken in through the air outlet 10, heat exchanged by the indoor heat exchanger 7, and then blown out through the vent 5 for heating and cooling.

(Effects of the invention) As explained above, according to the invention, the air in the bathroom is used to air-condition the living room, so the heat and water vapor in the bathroom are effectively used, and the humidity in the living room is particularly reduced. Helpful for improvement. The air conditioner was installed above the unit bath, and the air from the bathroom was sucked in through the unit bath's vent, and the drain was drained into the unit bath's drain pipe, so the space above the unit bath was effectively used and construction was completed. is easy.
