Abstract

The invention discloses an automatic control system for a solar water heater, which uses a circuit control device. The circuit control device is connected with a water pressure detection micro switch, a pipeline water level detection micro switch and an overflow water level detection micro switch, which are arranged on a solar heater pipeline, through a signal wire, and connected with a water-discharge electric control valve, a water-feeding electric control valve and a water tank electric control valve through a control wire, and the solar water heater is capable of automatically controlling overflowing and stopping water feeding, automatically discharging accumulated water in the pipeline, and automatically powering off, so that automation level of the solar water heater is improved. Water feeding, overflowing stopping, water discharging and powering off can be automatically completed only by pressing a water feeding button after a power start button is pressed, hot water can be used only by turning on a water switch, and automatic water discharging and automatic powering off can be completed only by turning off the water switch for stopping using water. The automatic control system is simpler and more convenient in operation and applicable to modification and improvement of solar water heaters.

Description

Technical field: [0001] The invention relates to a solar water heater, in particular to a circuit control of the solar water heater. technical background: [0002] Solar water heater is a green, environmental protection, energy-saving device, which is widely used at present, but solar water heater also has shortcomings in the process of use, mainly in the use of manual control, complex action, inconvenient operation, affecting the function and efficiency of solar water heater , the degree of automation is low, and the ideal purpose cannot be achieved through simple operation, so the phenomenon of inconvenient operation and waste of water often occurs during use, which causes certain troubles for people's use. Invention content: [0003] The purpose of the present invention is to use the circuit control device based on the circuit board, through the control of buttons, switches, water pressure, water level detection signals and electronically controlled valves, to achieve s...
