Title: Cock for supplying hot-water
Inventor: YONEDA KIYOSHI
IPC: F24D17/00
Filed: 1986-10-21
Abstract: PURPOSE:To permit a hot-water supplying port to take out only effective hot-water by a method wherein a closing piece for the three-way valve of a hot-water supplying cock is turned automatically by a shape memory alloy when water is heated to hot water, whereby the direction of the valve is switched to the direction of hot-water supplying. CONSTITUTION:A spring 14, provided on the shaft of a closing piece 13, is constituted of a shape memory alloy and is designed so that the spring constant is minimum under a normal temperature but becomes maximum under a certain temperature. When a knob 15 is closed, the closing piece 13 is located at the position of closing, the storing force of the spring 14 becomes minimum and the spring 14 is retained by a lock mechanism 16. When the knob 15 is turned counterclockwise by 90 deg., the communicating hole 13a of the closing piece 13 is opened and hot-water flows from the inlet port 8a of the main body 8 of a hot-water supplying cock to the outlet port 8b of the same. In this case, the spring 14 stores a potential energy obtained by turning the knob by 90 deg.. When the temperature of hot-water, passing through the main body 8 of the cock, has risen, the spring constant of the spring 14 becomes maximum and, further, the spring turns the closing piece 13 counterclockwise by 90 deg., whereby the hot-water flows from the inlet port 8a to another outlet port 8c. Accordingly, cooled hot-water may be thrown away through a releasing pipe 9 and only hot hot-water may be taken out of the hot-water supplying port.
