SANITARY CLEANING DEVICE

SANITARY CLEANING DEVICE

PURPOSE:To freely arrange a pump and a sub-tank, and prevent even leakage of cleaning water from a nozzle device with a simple valve structure by forming the pump as a non-self-priming type, and soaking the inside of the housing in the cleaning water. CONSTITUTION:A cleaning water tank 1 and a sub-t...

description PURPOSE:To freely arrange a pump and a sub-tank, and prevent even leakage of cleaning water from a nozzle device with a simple valve structure by forming the pump as a non-self-priming type, and soaking the inside of the housing in the cleaning water. CONSTITUTION:A cleaning water tank 1 and a sub-tank 3 are provided, and cleaning water is supplied to a nozzle device 2 from the sub-tank 3 through a pump 4. The pump 4 is formed as a nonself-priming type, and the inside of the housing 4a is always soaked in the cleaning water, and thereby, at restarting time, priming operation becomes possible by using the cleaning water remaining in the housing 4a as priming water. A water leakage preventive valve which can maintain a valve closed condition against a head at full water time in the cleaning water tank 1 and opens a valve at actuation time of the pump 4 by pressure of the pressurized cleaning water, is provided downstream of the pump 4.
