Claims

[Scope of utility model registration request]

(1) A heat pump refrigerant circuit including a compressor, a condenser, and an evaporator, a hot water storage tank in which the condenser and evaporator are arranged above and below at a predetermined interval, a solar collector, and a circulation pump. a heat medium circuit that uses water in the hot water storage tank as a heat collection medium; a distribution switching valve that selectively communicates the heat medium circuit with the upper or lower part of the hot water storage tank; and a heat collection temperature of the solar heat collector. control means for controlling the distribution switching valve based on the above, and the distribution switching valve has first and second ports connected to an upper high-temperature water side of the hot water storage tank and a lower low-temperature water side of the hot water storage tank. 3rd connected to water side
and a cylindrical valve body having a fourth port, an outgoing port connected to the circulation pump side of the heat medium circuit, and a return port connected to the ladder side to the heat medium outlet of the solar heat collector. , is slidably fitted into the valve body, and connects either one of the first and second ports or the third and fourth ports to the outgoing port in two different operating positions. 1. A water heater comprising: a piston having two communication passages that alternately communicate with a return port.

(2) Utility model registration In claim (1), the valve body includes a spring that biases the piston toward the first operating position, and a spring that biases the piston toward the second operating position against the spring. A water heater comprising: a control port for a control fluid to be moved to a certain position;

(3) In the utility model registration claim (2), the control port is connected to the discharge side of the circulation pump via a solenoid valve controlled by a temperature detection sensor provided in the solar heat collector. A water heater characterized by:

(4) Claim (2) of the utility model registration states that a pressure relief hole communicating with any one of the ports is formed at the end of the valve body opposite to the control port. Characteristic water heater.

(5) Utility model registration Claim (1) In claim (1), one end of each communication hole of the piston facing each port on the outward and return sides has a notch having a length approximately equal to the movement stroke of the piston. A hot water supply device characterized in that water and hot water are arranged in series along the axial direction.
