Claims

[Scope of utility model registration request]

The master valves 4 and 5 for flow rate adjustment are assembled to the slave valves 2 and 3 for minute adjustment fixed to the valve stem 1 at a certain interval so as to allow relative sliding within a certain range. A double-sided valve V1 on the hot water side and a single-sided valve V2 on the water side are provided, and the parent valves of the double-sided valve V1 on the hot water side and the single-sided valve V2 on the water side are provided so that the opening degrees of the slave valves 2 and 3 can be adjusted by relative movement of the valves 2 and 3. 4 and 5 are arranged in opposition to and away from the hot water side double-sided valve seats 10 and 11 formed at the hot water supply port 9 of the mixing valve chamber 8 and the water side single-sided valve seat 13 formed at the water supply port 12, respectively. Child valve 2 through child valves 2 and 3 during forward and backward movement.
．． 3 and the parent valve 4.5 are opened and closed in a correlated manner to reduce the passage area of water as it moves from the low temperature side to the high temperature side, and to set the passage area of hot water to be maximum in the middle, and A mixing type characterized in that the water passage area for hot water 1 and water on the high temperature side has a gradual opening increase/decrease rate using child valves 2 and 3, and that the upper limit position of the flow rate (passage area) of high temperature hot water is kept low. Hot water mixing device for water heater.
