Water inlet system of air energy water heater and air energy water heater with water inlet system

Abstract

The invention provides a water inlet system of an air energy water heater and the air energy water heater with the water inlet system. The water inlet system of the air energy water heater comprises a water pump, a reversing valve and a controller. The water pump is communicated with a water source. The reversing valve comprises a first connector, a second connector and a third connector, wherein the first connector, the second connector and the third connector are communicated to one another, the first connector is communicated with the water pump, the second connector is communicated with the water source, and the third connector is communicated with the air energy water heater. The controller is connected with the reversing valve and controls the first connector of the reversing valve to be communicated with the second connector or the third connector. By the adoption of the water inlet system of the air energy water heater, the situation that frequent startup and shutdown of a motor of the water pump are avoided can be guaranteed, and therefore the damage to the water pump and the motor can be avoided. The water inlet system of the air energy water heater is simple in structure, and can provide the pressured water source for the air energy water heater so as to meet the water demand of users in different regions. In addition, frequent startup and shutdown of the water pump and the motor of the air energy water heater can be avoided, so that the reliability is high, and the service life is long.

Description

technical field [0001] The present invention relates to the technical field of water heaters, more specifically, to a water inlet system of an air energy water heater and an air energy water heater having the same. Background technique [0002] Air-energy water heaters have become the fourth-generation water heaters after solar water heaters due to their advantages of low operating cost, environmental protection and pollution-free, and all-weather operation. At present, air-energy water heaters are mostly used in cities with tap water in the market, while in rural areas and without water heaters. In areas with running water, the use of air-energy water heaters is relatively limited, and during the use of air-energy water heaters, it is prone to damage to the motor due to frequent start and stop of the motor. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason,...
