Solar water heater controller

Abstract

The invention discloses a solar water heater controller. The solar water heater controller comprises a water heater water tank (1) and a main controller (3), wherein the solar water heater water tank is connected with a water consuming device (6) through a draining valve (2), a discharge valve (7) and a pipeline to form a hot water supply pipeline, a drainage electromagnetic valve (10) is mounted at the bottom of the hot water supply pipeline, the hot water supply pipeline is connected with a cold water source (4) through a water feeding electromagnetic valve (5), the main controller (3) is respectively connected with the water feeding electromagnetic valve (5), the draining valve (2) and a booster pump (17), an electric heater (16) is arranged in the water heater water tank (1) and is connected with the main controller (3), and a temperature sensor (12) is arranged in the hot water supply pipeline and is connected with the main controller (3). The temperature sensor (12) monitors temperature change information of water in the hot water supply pipeline so as to judge whether a user uses hot water, and stop or start the electric heater and the booster pump according to judgment results. According to the solar water heater controller, the temperature sensor realizes active electric leakage protection and automatic control in hot water boosting, the cost is low, and the service life is long and can be a few decades.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a solar water heater control device. Background technique [0002] The solar water heater is installed on the roof. Due to the measurement of the water temperature and water level in the solar water heater tank and the control of the emptying valve, in order to inform the user of the change information of the water temperature and water level in real time and to satisfy some functions of the user, the controller needs to be manually controlled, such as: For emptying valve control, etc., it is necessary to connect the controller with the sensor and the emptying valve on the water tank on the roof with wires. [0003] For the current large number of users: 1. In some cases, wires cannot be placed. For example, the early solar water heater has been installed, and the user has already decorated the house; 2. It is possible that the wire cannot be placed from the roof of the building to the us...

Problems solved by technology

[0003] For the current large number of users: 1. In some cases, wires cannot be placed

For example, the early solar water heater has been installed, and the user has already decorated the house; 2. It is possible that the wire cannot be placed from the roof of the building to the user's home, because the pipe well for the pipe and wire is already full, and the wire cannot be threaded; As the distance increases, the cross-sectional area of ​​the wire increases and the cost also increases

4. It takes more than two hours to put a line, and labor wages and safety issues are also not a small cost

Now the common usage is to use the imported booster pump with high sensitivity, the price is about 800 yuan, while the domestic booster pump with 100-200 yuan is not very sensitive and has a service life of only a few months.

[0007] In view of the above defects of the prior art, a new type of solar water heater controller is required to solve the problem of wireless signal transmission, active leakage protection and automatic Switch booster pump problem
