Description

COOLING AND HEATING IN ONE BATHROOM TYPE AIR CONDITIONER}

The present invention relates to an air-conditioning combined bathroom type air conditioner. More particularly, the present invention relates to an air-conditioning combined bathroom type air conditioner which eliminates the use of a four-way valve to reduce the manufacturing cost and quickly discharge air.

In general, an air conditioner is an air conditioner that is disposed in a room, a living room or an office, or a space such as a business store to maintain a comfortable indoor environment by controlling air temperature, humidity, cleanliness, and airflow.

In general, air conditioners are referred to as air conditioners for cooling indoors in summer. Some of these air conditioners reverse the flow of refrigerant in a refrigeration cycle to selectively perform cooling and heating functions, so-called heat pumps. There is a combined air-conditioning and air conditioner called a pump or an air conditioner for four seasons.

On the other hand, according to the change of living environment, most of the living spaces are equipped with bathrooms and toilets (hereinafter referred to as bathrooms), and these bathrooms always have water and drains to drain used water. Various fungi, bacteria, etc. are not only easy to breed, but also cause various odors, causing discomfort.

The use of the bathroom is not only mildew and odor, but also a lot of moisture generated when bathing, moisture condensation on the wall, glass, etc., uncomfortable in winter, it gives cool to the living room, room, and temperature difference to health for the elderly There is a problem that may adversely affect.

In consideration of these problems, a bathroom-type air conditioner having a refrigeration cycle component is installed in the bathroom to cool or heat the bathroom.
