Title:
WATER SUPPLY DEVICE
Document Type and Number:
Japanese Patent JPH06346860
Kind Code:
A
Abstract:

PURPOSE: To provide a water supply device improving quantitative water feeding performance and preventing the generation of microorganisms since soil is unliable to adhere by connecting a quantitative pump to a feed water pump so as to feed water in the feed water tank quantitatively by the quantitative pump.

CONSTITUTION: A water supply device 1 for supplying water to an ice making plate in a refrigerator, for instance, is formed by connecting a rotary pump 4 or a tube pump 8 as a quantitative pump to a feed water tank 2 through a joint 3. Water in the feed water tank 2 is supplied to the ice making plate by the rotary pump 4 or tube pump 8, and quantitative water supply control is performed according to the rotating speed or rotating time of a motor. On the other hand, the water in a feed water hose 29 is returned to the feed water tank 2 by the reverse rotation of the motor. Quantitative water feeding performance is thereby improved, and the contact between water and outside air is cut off. The inside of the water feed hose 29 is maintained in the water non-stored state, so that soil is unliable to adhere thereto, and the generation of microorganisms can be prevented.
