Abstract
An anti-freezing solar water heater by pipeline evacuation comprises a water tank, a heat-insulation layer, an exhaust outlet, a two-position three-way valve, a temperature control device and a water pipe. The heat-insulation layer is arranged on the water tank, the temperature control device is arranged at one end of the water tank, the exhaust outlet is arranged on the upper portion of the water tank, the two-position three-way valve is added between the water tank and the water pipe, one joint of the two-position three-way valve is connected with a lower joint of the water tank, another joint of the two-position three-way valve is connected with the water pipe, the third joint of the two-position three-way valve is connected with the exhaust outlet, a hot water valve and a water feed valve are arranged on the lower portion of the water pipe, and a sprayer is arranged on one side of the hot water valve. The anti-freezing solar water heater by pipeline evacuation is reasonable in structure, can be supplied with cool water or supply hot water conveniently by changing intercommunication modes of the two-position three-way valve, can solve the problem of freezing of the water pipe fundamentally by means of evacuating residual water in the water pipe in time, and thereby fine performance of the solar water heater can be guaranteed even when the solar water heater is used in cold regions.
Description
Technical field
The utility model relates to a kind of tube emptying water heater, relates in particular to a kind of tube emptying antifreezing type solar water heater.
Background technology
Solar water heater is with superiority such as its energy-saving and environmental protection, obtained in recent years applying widely, solar water heater water tank and with certain distance is all arranged between the water spot, this connection water pipe therebetween, no matter be go up behind the water or use hot water after all have Yu Shui in the water pipe, when ambient temperature is low, the water in the water pipe is freezed, severe patient can cause water pipe from freezing crack, has directly influenced the serviceability of water heater.
Summary of the invention
The purpose of this utility model is to provide the tube emptying antifreezing type solar water heater of the surplus water of a kind of water pipe of emptying in time.
To achieve these goals, the technical scheme that the utility model adopted is: tube emptying antifreezing type solar water heater, comprise water tank, heat-insulation layer, exhaust outlet, two position three-way valve, attemperating unit, water pipe, it is characterized in that being provided with on the water tank one deck heat-insulation layer, water tank one end is provided with attemperating unit, and water tank upper is provided with exhaust outlet, add two position three-way valve between water tank and water pipe, the interface and the water tank bottom interface of two position three-way valve join, another interface water receiving pipe, and the 3rd interface and exhaust outlet join, the water pipe bottom is provided with hot water valve, water supply valve, hot water valve one side is connected with shower nozzle.
The utility model is rational in infrastructure, as long as change the mode that is interconnected of two position three-way valve, can go up cold water easily, use hot water, surplus water in the emptying water pipe, just fundamentally solved the problem that water pipe freezes,, also can guarantee the good serviceability of solar water heater even at severe cold areas.
