Solar water tank timing automatic water supply controller

Abstract

The invention discloses a solar water tank timing automatic water supply controller, which is characterized by comprising a 220V alternating current power supply, a 12V direct current power supply, a timing trigger circuit, a relay driving circuit, a water tank water supply indicating and electromagnetic water valve circuit and a water tank water fullness detecting circuit. Solar users cannot get rid of the water supply trouble, because the quality of an automatic water supply controller is poor, a water level sensor can easily generate water scales, the water level sensor can have a failure after the short-time use, the whole set of automatic control equipment is in failure, and the automation realization of a solar water heater is hindered. The core problem for improving the grade of the solar water heater and completing the functions of the solar water heater is to solve the problem that the sensor can easily generate water scales. A contact type water tank water fullness detecting circuit with good universality perfectly solves the difficult problem of water scale formation, and the goals that the water supply controller can be easily popularized and generalized, the service life is long, and the solar water heater realizes the automatic control without the fear of trouble in the rear are realized.

Description

technical field [0001] The invention belongs to the technical field of electronic control, and relates to a timing automatic water filling controller for a solar water tank. Background technique [0002] There are very few manufacturers of solar water heater water tanks that are equipped with automatic water supply controllers like color TVs equipped with remote controls. The main reason is that the quality of the automatic water supply controllers produced is not good enough. It will fail in a shorter time, which will cause a lot of trouble or loss to users and solar water heater manufacturers. Therefore, solar water heater manufacturers and distributors are reluctant to promote automatic water supply controllers. However, users of solar water heaters cannot get rid of the trouble of supplying water, and cannot achieve the purpose of convenience and water saving. The culprit is that the quality of the automatic water filling controller is not good enough, and the water le...
