Description

  The present invention relates to a bathroom heater that performs bathroom heating using radiant heat as a heating device.

  As a conventional bathroom heater, a hot air type bathroom heater installed on the ceiling or wall of a bathroom is known. This warm air type bathroom heater sucks air in the bathroom with a blower provided inside the heater, warms the sucked air with a heating means such as an electric heater, and supplies it as warm air into the bathroom again. It has been known.

  However, in such a case, it is suitable for indoor preheating as a step before the bather enters the bathroom, but when the bather is in the bathroom, this warm air directly hits the skin of the bather and lowers the sensory temperature. There was a problem that the feeling of comfort was impaired.

  In recent years, therefore, bathroom heaters using radiant heat have been known. This radiant bathroom heater is equipped with a far-infrared electric heater (for example, a carbon lamp heater) at a position facing the bathroom, and supplies radiant heat to a bather in the bathroom with a reflector. . However, in the case of a bathroom heater that uses this radiant heat, the heat that is generated from the carbon lamp heater that is used causes heat deformation of the reflector and the resin that makes up the interior of the heater, which adversely affects the function and performance of the bathroom heater. There was a problem that could give.

  In order to solve the above-mentioned problem, a method of operating the blower to cool the inside of the device when heating with radiant heat by the blower provided inside the heater can be considered. (For example, refer to Patent Document 1).

  However, in this case, when heating with radiant heat, the blower is always operated for cooling, and the cooling air is blown out from the front of the bathroom heater to the bather. The problem remains that hot air hits and lowers the sensible temperature.
