  • Patent number: 9746197
    Abstract: A bathroom air-conditioner includes a refrigerant circuit in which a compressor, a radiator, a decompressing mechanism and a heat absorber are connected with one another through a pipe, a circulating air-course, and a ventilating air-course. In the circulating air-course, the radiator and a circulating fan for circulating the air of the bathroom are placed. In the ventilating air-course, the heat absorber and a ventilating fan for discharging the air from the bathroom to the outside are placed. The heat absorber makes the refrigerant absorb heat from the air of the bathroom, and the radiator makes the refrigerant dissipate heat to the air of the bathroom for heating the bathroom. During the heating of the bathroom, when a temperature of the bathroom becomes higher than a given temperature, a controller reduces an air-blow amount from the ventilating fan.

  • Patent number: 8602398
    Abstract: A bathroom sauna device having a heating device for heating air in a bathroom, a humidifying device for humidifying the air in the bathroom, and an airflow path for sending the air, which is adjusted in temperature and humidity by the heating device and humidifying device, to the bathroom. The temperature and humidity of the air in the bathroom are controlled by the heating device and humidifying device to a temperature and humidity immediately before which a human body starts sweating.

  • Patent number: 8327473
    Abstract: A sauna cabinet is humidified and heated without airborne perceivable water drops by the use of a fine spray. The user can thus remain comfortably in the sauna cabinet that is free of airborne perceivable water drops. The user's view is also not clouded by mist. Accordingly, the user can enjoy viewing images and reading books in the sauna cabinet, and a user's sensible temperature distribution in the sauna cabinet is also uniform. This sauna equipment thus provides uniform temperature and humidity even in a large bathroom. The sauna equipment includes a first circulator and a second circulator for circulating air in the sauna cabinet, an air heater for heating supplied air, and a water atomizer for turning supplied water into fine water drops.

  • Patent number: 8070138
    Abstract: A sauna apparatus includes an air blower, a blow channel and a humidifier. The air blower suctions and blows air. The blow channel conveys the suctioned air and humidified air. The humidifier has a sprayer that sprays humidifying water into the air passing through the blow channel for humidification, and a spray-water droplet splitter installed in a direction to which the sprayer sprays the water for humidification. By letting the sprayed water droplets collide with the splitter, the water droplets are split into much finer water droplets.

  • Publication number: 20110100043
    Abstract: The ventilating air-conditioning system includes an air supply fan; an exhaust fan; a compressor; a first heat exchanger heat-exchanging between outdoor air sent from the air supply fan and a refrigerant; an expansion mechanism; a second heat exchanger heat-exchanging between air in a sanitary space sent by the exhaust fan and a refrigerant; and a refrigerant circuit piped so that a refrigerant circulates in order of the compressor, first heat exchanger, expansion mechanism, and second heat exchanger, or in order of the compressor, second heat exchanger, expansion mechanism, and first heat exchanger. The system heats or cools an indoor space while ventilating a sanitary space by transferring heat between the first heat exchanger and second heat exchanger through a refrigerant.
