Further, a fuel on / off valve is provided between the catalyst combustor and the fuel tank, and the fuel on / off valve is opened / closed by a signal from a temperature detecting means mounted in the cleaning liquid tank. The combustion amount of the catalytic combustor is determined by the temperature in the cleaning liquid tank. By performing this control, there is an effect that cleaning can be performed at the temperature of the cleaning liquid that the human body feels comfortable during local cleaning.
[0034]
Further, the portable cleaning apparatus according to claim 2 is provided with a display unit for displaying that the temperature of the cleaning liquid detected by the temperature detecting means has reached the set temperature, so whether or not the temperature of the cleaning liquid has reached the set temperature. Since this can be understood by looking at the display section, it has the effect that the cleaning liquid can be used without spraying it and confirming the temperature.
[0035]
Further, the portable cleaning apparatus according to claim 3 includes temperature setting means for setting the temperature of the cleaning liquid and a cleaning liquid temperature display unit for displaying the temperature of the cleaning liquid, and the temperature of the cleaning liquid can be set to a desired temperature. Since the cleaning liquid temperature display section can be checked to see if the temperature has reached, the comfort is further improved and the usability is improved.
[0036]
The portable cleaning device according to claim 4 locks the switching valve to the cleaning liquid circulation path until the temperature of the cleaning liquid detected by the temperature detecting means reaches a predetermined temperature. Even if it is made to eject, the cleaning liquid is not ejected, and there is an effect that no discomfort is obtained.
