Abstract

The invention discloses a water supply system with whole house pressurization and water return functions. The water supply system comprises a water heater, a first one-way valve, a pressurizing branch, a water return branch, a cold water branch and a control valve, wherein the water heater is connected to a water inlet pipe and a water outlet pipe, the water outlet pipe is used for connecting a hot water end of a water consuming point, a first one-way valve; the pressurizing branch is provided with a pressurizing branch first end and a pressurizing branch second end, one end of the water return branch is connected to the first water outlet end, the other end of the water return branch is connected to the second end of the pressurization branch, the cold water branch is provided with a cold water branch first end and a cold water branch second end, and the control valve is used for controlling one of the cold water branch and the water return branch to communicate. According to the water supply system with the whole house pressurization and water return functions, multiple functions can be achieved only by arranging one water pump, the complexity of the system is simplified, and meanwhile the equipment cost is prevented from being increased.

Description

technical field [0001] The invention belongs to the technical field of water heaters, and in particular relates to a water supply system with the functions of pressurizing the whole house and returning water. Background technique [0002] With the improvement of people's material living standards, the requirements for bathing comfort of water heaters are getting higher and higher. For users of self-built water heaters in townships and rural areas, there are still many situations where the water pipe network is not connected or the water pressure is unstable. For this type of users, there is a demand for the whole-house supercharging function, and there is also a demand for zero-cold water comfort. [0003] The current main solutions for the problems referred to above are as follows: one, the water outlet pipe of the water tank is provided with a circulating water pump, and the water inlet pipe of the water tank is provided with a check valve. In this scheme, the circulatin...
