Title:
CAR WASHING MACHINE
Document Type and Number:
Japanese Patent JP3938031
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a car washing machine in which water draining in a high-pressure circuit can be carried out in a state of keeping water in a high-pressure pump.
SOLUTION: A body 10 of a car washing machine is provided with high-pressure nozzles 13, 14 and a high-pressure pump 20 is installed on the body 10. The high-pressure pump 20 is connected to a water feeding hose 21 extending from a ground water supplying means 5 to the high-pressure nozzles 13, 14 via a high pressure hose 23. There is a water draining means 30 for performing water draining with water W remaining in the high pressure pump 20. When the high-pressure pump is operated for performing a first (initial) morning cleaning operation, residual water in the high-pressure pump enables high-pressure water to be rapidly (at once) supplied and then the high-pressure cleaning of a first car is performed while making a waiting time minimum, so that a car washing time does not become to be extended. Since residual water in the high-pressure pump eliminates the feeding of water for preliminary water and the like and even if the pump is of a multi-stage type, it is possible to prevent its damage from occurring. Water draining for the water feeding hose or the high-pressure hose can be carried out by the water draining means with water remaining in the high-pressure pump.
