Combined valve, hot water system and hot water system control method

Abstract

The invention provides a combined valve, a hot water system and a control method for the hot water system. The combination valve includes a valve seat, a water supply valve and a selection valve, and the water supply valve and the selection valve are fixed on the valve seat; the valve seat is provided with tap water inlet, hot water outlet, cold water outlet, hot water inlet and water inlet and outlet, The water inlet is connected to the cold water outlet, and the water inlet and outlet are connected to the tap water inlet through the water supply valve; the selection valve includes a first valve body and a second valve body that are mutually linked and controlled to realize alternate switching, and the water inlet and outlet are connected to the hot water outlet through the first valve body connected, the hot water inlet is connected with the hot water outlet through the second valve body. The combination valve is directly connected to tap water, energy-consuming water heaters and solar water heaters, and controls water supply and hot water source selection through its own integrated valve, which facilitates users to switch hot water sources, simplifies connecting pipelines, and facilitates the installation of water heaters.

Description

technical field [0001] The invention relates to a water heater, in particular to a combined valve, a hot water system and a control method for the hot water system. Background technique [0002] At present, water heaters are divided into energy-consuming water heaters (such as electric water heaters and gas water heaters) and solar water heaters according to heating methods. Energy-consuming water heaters usually have independent water inlets and outlets, while solar water heaters have the same inlet and outlet. Users who have both energy-consuming water heaters and solar water heaters installed in their homes usually need to close the valve of one of the water heaters and open the valve of the other water heater when choosing to use different hot water sources. During the water heater installation process, it is necessary to set corresponding valves for the energy-consuming water heater and the solar water heater to independently control the water in and out, and the valves...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a combined valve, hot water system and a control method for the hot water system, which solves the defects in the prior art that it is inconvenient for users to switch hot water sources, and the connecting pipeline of the water heater is too complicated and cumbersome to install. Through the combination valve, it is convenient for the user to switch the hot water source, simplify the connection pipeline of the water heater, and facilitate the installation of the water heater
