Solar water heater with automatic control device

Abstract

The invention relates to a solar water heater with an automatic control device. The solar water heater is a household solar water heater suitable for cities and rural areas. A water inlet and a water outlet are formed in the two sides of the top of a water storage tank correspondingly. Two liquid level sensors are arranged and installed up and down in the positions, close to one side of the water inlet, in the water storage tank. The upper liquid level sensor is used for controlling a water adding signal, and the lower liquid level sensor is used for controlling a water level lower limit instruction. Water outlet nozzle equipment is arranged at the bottom of the water storage tank. A water flow sensor is installed on the inner side of the water outlet nozzle so that the flowing water speed and the flowing water quantity can be controlled. The two liquid level sensors and the water flow sensor electrically communicate with a single chip microcomputer chip, so that a program control circuit is formed. The upper liquid level sensor is connected with a NOT gate in series and then is electrically connected with a single chip microcomputer. Compared with the prior art, the solar water heater with the automatic control device is simple and reliable in circuit control principle, water inlet operation, water outlet operation and the water outlet flow quantity are comprehensively controlled through the multiple sensors, the using safety of the solar water heater can be ensured, and water is saved.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of solar energy, and relates to a household solar water heater suitable for urban and rural areas, in particular to a solar water heater with an automatic control device. [0003] technical background: [0004] Most of the solar water heaters sold on the market are ordinary solar water heaters. These water heaters cannot avoid the waste of water resources caused by people filling too much water or forgetting to fill water. Bring inconvenience; Now, although some high-grade solar water heaters have been installed with devices such as automatic replenishment and full water alarms, the product application is not extensive, and the cost is too high, so it is not easy to promote. [0005] Invention content: [0006] The purpose of the present invention is to overcome the shortcomings of the existing water heaters that the water storage and water level are not easy to be intelligently controlled, and seek ...
