PURPOSE:To complete a given cleaning process and to prevent accumulation of an oil content on a wall surface, by a method wherein, in case a blower is driven during a cleaning process, the cleaning process is temporarily suspended and blast function is given priority, and when the blower is brought to a stop, cleaning is restarted from the starting point of the cleaning process. CONSTITUTION:When a blower is driven during a cleaning process, by means of a signal from a blower switch 12, a heater 2 is disconnected in a condition in that a flip flop FF1 is set, and a flip flop FF2 is reset to bring a pump 5 into a stop. In which case, a delay timer 11, simultaneously, is cleared. Thus, the cleaning process is temporarily suspended, but since the flip flop FF1 is left set, with the blower switch 12 turned OFF, the heater 2 is actuated to restart cleaning from the starting point of a normal cleaning process. This enables completion of specified one complete cleaning per a day through compensation of the suspended cleaning process, and enables an oil contact to be prevented from accumulation on an inner wall surface so as to keep the temperature of a cleaning solution at higher than a given temperature. |
