Abstract

The utility model discloses an antifreezing device for pipelines of solar water heaters in cold regions. It includes a solar water heater, an insulated water pipe, a water heater, a solenoid valve, a running water pipe and a micro water pump. The solar water heater is connected with the water heater in the house through an insulated water pipe. A solenoid valve is arranged on the thermal insulation water pipe near the solar water heater. The thermal insulation water pipe in the house is connected with the running water pipe through a three-way valve. A miniature water pump is arranged on the thermal insulation water pipe between the three-way valve and the water heater. The utility model has simple structure and reasonable design. When the solar water heater is not used, the water stored in the thermal insulation water pipe can be discharged in time by opening the electromagnetic valve, so that the thermal insulation water pipe will not be blocked due to freezing. Especially suitable for installation and use in high latitude areas.

Description

Antifreeze device for solar water heater pipelines in cold areas

technical field

The utility model relates to protection equipment for solar water heaters, in particular to an antifreeze device for pipelines of solar water heaters in cold regions.

Background technique

At present, solar water heaters have been widely used by people. However, in high latitude areas, due to the low temperature and short sunshine time in winter, the water pipes of ordinary solar water heaters are controlled by indoor valves, and there is always water in the water pipes, which is prone to freezing when the temperature is low. For solving this problem, the common way is to add electric heating belt in the water pipe insulation layer, which not only consumes energy, but also is prone to fire.

Contents of the invention

The purpose of the invention of the present utility model is to provide an anti-freezing device for pipelines of solar water heaters in cold regions that can effectively overcome the above-mentioned problems and prevent water from storing in the water pipes when not in use.

The technical scheme of the present utility model is such that the pipeline antifreeze device of the solar water heater in the cold area comprises a solar water heater, a thermal insulation water pipe, a water heater, a solenoid valve, a running water pipe and a miniature water pump;

The solar water heater is connected with the water heater in the house through the heat preservation water pipe; the solenoid valve is installed on the heat preservation water pipe near the solar water heater; The water pipe is connected to the running water pipe through a three-way valve; the micro-water pump is installed on the heat-preserving water pipe between the three-way valve and the water dispenser.

The utility model has simple structure and reasonable design. Under the situation of not using the solar water heater, the water stored in the thermal insulation water pipe can be discharged in time by opening the electromagnetic valve, so that the thermal insulation water pipe will not be blocked due to freezing. It is especially suitable for installation and use in high latitude areas.

Description of drawings

Figure 1 is a schematic plan view of the overall structure of the pipeline antifreeze device for solar water heaters in cold regions.

Among them: 1 solar water heater, 2 thermal insulation water pipe, 3 water heater, 4 solenoid valve, 5 three-way valve, 6 running water pipe, 7 micro water pump, 8 house.

Detailed ways.

As shown in the accompanying drawings, the antifreeze device for pipelines of solar water heaters in cold regions includes solar water heaters 1, thermal insulation pipes 2, water heaters 3, solenoid valves 4, tap water pipes 6 and micro-water pumps 7;

The solar water heater 1 is connected with the water heater 3 in the house 8 through the thermal insulation pipe 2; the electromagnetic valve 4 is installed on the thermal insulation pipe 2 near the solar water heater 1; The thermal insulation water pipe 2 described in the house 8 is connected with the described running water pipe 6 through a three-way valve 5; Described miniature water pump 7 is arranged.

The working principle of the utility model is that when the solar water heater is not in use, the solenoid valve is in a normally open state, so that the heat preservation water pipe communicates with the outside world. There will be no clogging due to freezing. When hot water is needed, the micro-water pump is turned on and the solenoid valve is closed simultaneously, and the hot water is sucked into the house for use through the thermal insulation pipe. When not in use, turn off the micro water pump and open the solenoid valve at the same time. At this time, the micro water pump is set to delay closing, and the water in the heat preservation water pipe will be emptied under the joint action of the external air and the micro water pump, so as to achieve the purpose of not freezing the heat preservation water pipe.
