Water control device of heat pump water heater

Abstract

The invention discloses a water control device of a heat pump water heater. The water control device comprises the water heater with a heating water tank, a leading-out pipeline is installed on the water heater and comprises a water inlet pipeline, a water outlet pipeline, a circulation pipeline and an air guiding pipeline, wherein the water inlet pipeline, the water outlet pipeline, the circulation pipeline and the air guiding pipeline are communicated with the heating water tank. A five-way pipe is installed on the water inlet pipeline, and a first one-way water inlet assembly, a second one-way water inlet assembly and a first one-way air guiding assembly installed inside the five-way pipe are matched with the water inlet pipeline, the water outlet pipeline, the circulation pipeline and the air guiding pipeline in structure. The water control device of the heat pump water heater ensures pressure balance inside the heating water tank and the pipelines, water is prevented from flowing back, the heat pump water heater is protected, it is avoided that because of negative pressure, water flow speed is affected, the stability of water flow is guaranteed, the five-way pipe replaces a traditional external one-way water inlet valve and a traditional external one-way air inlet valve, the number of components is small, the water control device is free of limits from installing positions, convenient to install and free from damage by external objects, and the service life of the water control device is effectively prolonged.

Description

technical field [0001] The invention relates to a control component of a heat pump water heater, in particular to a water control device of the heat pump water heater. Background technique [0002] In the daily use of existing heat pump water heaters, the heating water tank is generally hung on a high place on the wall. When the water pressure is insufficient or the water is cut off, the water in the heating water tank will flow back from the water inlet to the water inlet pipe under the action of gravity, making the heating water tank There is a lack of water inside. The lack of water in the heating water tank will cause a negative pressure in the tank. When the user turns on the heat pump water heater, due to the negative pressure in the heating water tank, the water will quickly flow out along the water inlet pipeline, heating water tank, and water outlet pipeline. . In addition to making the water flow unstable and affecting the heating effect of the heat pump water ...

AI Technical Summary

Problems solved by technology

Although the above-mentioned valve body prevents backflow to a certain extent, balances the pressure of the heating water tank and the pipeline, and stabilizes the water flow velocity, the above-mentioned valve body is generally placed on the pipeline, and there are many installation parts, and because the installation space of the water heater itself is relatively small. Small, the installation of the valve body is easily restricted by the installation position, which makes its installation very troublesome

In addition, during use, dirt is easy to accumulate in the pipeline and the inner tank of the heating water tank, and even hinders the flow of water in the pipeline and the inner tank of the heating water tank, which also seriously affects the normal use of the water heater
