Automatic water feed evacuating and pressurizing device and using method thereof

Abstract

Disclosed are an automatic water feed evacuating and pressurizing device and a using method thereof. The automatic water feed evacuating and pressurizing device comprises a water tank and a water pipe, and the upper surface of the water tank is provided with vent holes. The automatic water feed evacuating and pressurizing device is characterized in that an underneath type water temperature and level sensor is arranged in the water tank, a pressurizing pump is arranged at the joint of the bottom of the water tank and the water pipe, the U-shaped water pipe in the water tank is a siphoning pipeline, a normally-closed electromagnetic valve is arranged at an upper water port of the water pipe, a normally-opened electromagnetic valve is arranged at a lower water port of the water pipe, and the water temperature and level sensor, the normally-opened electromagnetic valve, the normally-closed electromagnetic valve and an evacuation control switch are connected with a control instrument respectively. The using method of the automatic water feed evacuating and pressurizing device includes steps of feeding water, evacuating fed water, discharging, evacuating the discharged water, and replenishing water. Automatic water feeding and discharging and automatic evacuating and water discharge pressurizing of a solar water heater can be controlled, evacuation and water supply are realized under the joint action of the siphoning pipeline and the pressurizing pump in the water tank, damage and cracking of pipelines in winter are avoided, and the automatic water feed evacuating and pressuring device is simple in structure, convenient to use and applicable to promotion and sales.

Description

Technical field [0001] The invention relates to the technical field of solar water heaters, in particular to an automatic water filling and emptying pressurizing device and a use method thereof. Background technique [0002] Solar water heater is a very popular type of water heater, which is energy-saving, environmentally friendly, and easy to use. However, some functions and settings of solar water heaters have caused some troubles for people. For example, solar water heaters cannot be shared with automatic water supply and emptying. There is a conflict between water and emptying in the function settings, so users can only choose one function, which is inconvenient to use; when solar water heaters are used in some rural areas or houses with low drops, low hot water pressure and unstable water pressure often occur The situation brings a lot of inconvenience to users. Summary of the invention [0003] In order to make up for the shortcomings of the prior art, the present invention...
