CLEANING DEVICE

PROBLEM TO BE SOLVED: To achieve a cleaning device which permits the temperature of cleaning water so as to prevent hot water from being jet as the cleaning water even if a water heater without a temperature adjustment function for the cleaning water is used and can match with water heaters differing from manufacture to manufacturer. SOLUTION: The cleaning device has a cleaning unit 3 mixing hot water supplied from the water heater 5 and a detergent together and supplying the mixture to a cleaning nozzle as the cleaning water and a control device 26 controlling the cleaning water supply action of the cleaning unit 3. The control device 26 adjusts the flow of the hot water to a specified value and reduces the flow of the hot water from the specified value by a fixed value and carries out a hot water discharging action to discharge the hot water for a prescribed period at the time when the temperature sensing means senses a first upper limit temperature or above, when detecting a prescribed error condition, in other words at the time when a cleaning action is initiated or when the temperature sensing means senses the first upper limit temperature or above at the time of a preceding cleaning action at the time when the cleaning action is initiated.
