Description

  Aspects of the present invention relate to a sanitary washing device for washing a human body part.

  In the conventional sanitary washing device, a hot water storage tank, a heat exchanger, etc. are arranged inside the casing, and the temperature difference between the standby temperature in the toilet room and the temperature inside the casing becomes large depending on the season. Therefore, dew condensation may occur inside the casing due to the temperature difference. In addition, there is a type in which warm water is sprayed from a cleaning nozzle to wash a human body, and steam (wet air) generated from the warm water may enter the casing to cause dew condensation inside the casing.

  In order to suppress the generation of dew condensation, the height of the rear wall of the lower case is lowered as much as possible in the conventional sanitary washing device. As a result, it is possible to prevent the air inside the casing from staying inside, and it is easy to perform air replacement between the air inside the casing and the outside air outside the casing, and it is possible to suppress the occurrence of dew condensation. (Patent Document 1)

  However, if the height of the rear wall of the lower case is low, water may enter the inside of the casing from between the lower case and the upper case, and the inside may be flooded.
