PURPOSE:To prevent the propagation of germ in the evaporator by spraying the pasteurization liquid in the evaporator. CONSTITUTION:During the predetermined time after the turning off of the pasteurization liquid spraying nozzle fixed to the evaporator 3 and the blower switch 11, a timer circuit 21 for operating the switch 20a to close the power circuit for the driving motor 9 of the pasteurization liquid supply pump 7 is provided. Then the pasteurization liquid is sprayed through the nozzle to the evaporator 3. When turning off only the blower switch 12, the movable contact 12c will connect between the terminals 12e and 12f while since the air-conditioner switch 13-2 is turned on, the current will flow through the relay contact 20a and the motor 9 by the function of the battery 10, terminal 12e of the switch 12, switch 13-2, circuit 21, etc. Consequently the pasteurization liquid is sprayed through the nozzle of the spray tube 6 into the evaporator 3. |
