The present invention relates to a water-cooling bathroom-type air conditioner for both heating and cooling.

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.
