Title:
WATER HEATER FOR DISH WASHER
Document Type and Number:
Japanese Patent JP3741797
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a safety device for a dish washer from being vainly operated by rapidly supplying a predetermined amount of warm water to the washer side at the time of starting initial supplying of hot water.
SOLUTION: An automatic water supply valve 53 for controlling water supply amount to hold temperature of warm water substantially constant is provided at an outlet side of a warm water generating part of a feed water tube 10. A bypass tube 62 provided with a bypass valve 63 is provided between an inlet side and an outlet side of the valve 53. The valve 63 is always closed, and controlled to be opened only at the time of starting initial hot water supply. At the time of the start of the initial hot water supply, temperature raising capacity of a heat pump is low, and hot water output amount of the valve 53 is limited, but the valve 63 is opened, and hence a large amount of warm water can be supplied to a dish water via the tube 62 even when the temperature rise remains insufficient. In the case that a safety device for stopping its operation when warm water supply amount is a specified value or less is provided, it prevents the safety device from being operated.
