Pipeline defroster of solar water heater

Abstract

The invention relates to a pipeline defroster of a solar water heater. The pipeline defroster of the solar water heater comprises the solar water heater and a water pipe connected with the solar water heater, wherein the tail end of the water pipe is provided with an anti-freezing water tank; the lower end of the anti-freezing water tank is provided with an electric heater; the electric heater is connected with an attaching plug; the anti-freezing water tank is also provided with a temperature controller. According to the pipeline defroster disclosed by the invention, the anti-freezing water tank is arranged at the tail end of the water pipe, and convection is generated by utilizing hot water in the anti-freezing water tank and water in the water pipe, and therefore, the water in the water pipe is prevented from being frozen; the water in the anti-freezing water tank is heated through the electric heater, and temperature control is performed through the temperature controller, and therefore, the maintenance cost of the solar water heater is reduced, and the service life of the solar water heater is prolonged.

Description

technical field [0001] The invention relates to an antifreeze device for pipelines of solar water heaters. It belongs to the technical field of solar water heaters. Background technique [0002] With the rapid development of social economy, in recent years, solar water heaters have been integrated with buildings and become a part of buildings. The industry has developed rapidly, and the number of users has increased year by year. The market in the north and even the alpine regions of the northeast has also developed rapidly. [0003] Since the solar water heater must be installed outdoors where it can receive sunlight, it is inevitable that some of the pipelines will be exposed to the outside. In winter, especially in the north and northeast regions, due to the relatively low outdoor air temperature, it is very common for pipelines to freeze or be damaged by freezing, which makes solar water heaters unable to work normally, and maintenance is troublesome and costly.

AI Technical Summary

Problems solved by technology

In winter, especially in the north and northeast regions, due to the relatively low outdoor air temperature, the phenomenon of freezing or freezing of pipelines is very common, making solar water heaters unable to work normally, and maintenance is troublesome and costly.

[0004] At present, the commonly used solution is to cover the outer surface of the water pipe of the solar water heater with a layer of insulation tape, but in the north or northeast region, when the outdoor temperature is extremely low, the effect of the insulation tape is not good, and the pipe is still relatively easy to freeze or freeze.
