Controller for water feeding and heating of solar water heater

Abstract

The invention discloses a controller for water feeding and heating of a solar water heater, belonging to the technical field of solar control. The controller comprises a CPU (central processing unit) processing module, a water level sensor, a water supply device, a heating device, a key module and a temperature sensor, wherein the CPU processing module is used for operation, processing and control; the water level sensor is connected with the CPU processing module and used for detecting a water level in the solar water heater; the water supply device is connected with the CPU processing module and can be used for automatically feeding water; the heating device is connected with the CPU processing module and can be used for increasing the water temperature; the key module is connected with the CPU processing module and used for setting the water level and temperature data; the temperature sensor is connected with the CPU processing module through a switch and used for detecting water temperature in the solar water heater; the CPU processing module is a programmable CPU processing module; the temperature sensor is a digital temperature sensor; and the key module adopts matrix type keys. The controller disclosed by the invention has the beneficial effects that: the operation is simple, the water feeding and heating functions are added, and the problem that people cannot take a bath due to the excessively low water temperature in rainy days and in the morning is solved.

Description

technical field [0001] The invention relates to a controller, in particular to a controller for solar water filling and heating, and belongs to the technical field of solar control. Background technique [0002] Solar energy is deeply loved by consumers for its environmental protection and power-saving functions. Existing solar water heater product just utilizes solar energy alone to heat water. When the water in the solar energy is used up, the water needs to be filled manually. Sometimes, after a busy day, you will forget to fill the water after taking a shower. Simultaneously, when the weather is cloudy and rainy, the water temperature in the solar water heater cannot reach a comfortable temperature at all, and if you want to take a bath in the morning, the water temperature cannot reach the requirement either. Contents of the invention [0003] Aiming at the problems in the prior art above, the present invention provides a controller for solar water supply and heatin...
