Abstract
The utility model discloses a gas water heater capable of automatically draining water and preventing congealment, which comprises an outer shell, a combustion chamber, a heat exchanger, a water tank coil pipe, a cold water inlet pipe, a hot water outlet pipe, a gas valve, a water valve, a control device, a temperature control switch, an electric three-way valve and a drainage pipe, wherein the water valve is arranged on the cold water inlet pipe; the cold water inlet pipe is connected with a cold water inlet joint; the electric three-way valve is arranged on the cold water inlet pipe between the cold water inlet joint and the water valve; one end of the drainage pipe is connected with the electric three-way valve, the other end extends out after penetrating through the outer shell; the temperature control switch is connected with the electric three-way valve and the control device, and the electric three-way valve is connected with the control device; and the temperature control switch is arranged on a water guiding pipe of the heat exchanger. By adopting the structure, when the external temperature is low, the temperature control switch acts, a water outlet end of the electric three-way valve is communicated with a pipeline on the upper part of the electric three-way valve, and water is drained through the water guiding pipe, thereby effectively preventing the heat exchanger and the cold water inlet pipe from cracking; and the gas water heater is convenient in use.
Description
Technical field
The utility model relates to a kind of gas heater.
Background technology
Currently available technology, the gas heater that a kind of Auto-drainage is antifreeze, comprise shell, combustion chamber, heat exchanger, water tank coil pipe, cold water inlet, hot water outlet pipe, gas valve, water valve and control device, cold water inlet is connected with water tank coil pipe, water tank coil pipe is communicated with the water inlet end of heat exchanger, and the water side of hot water outlet pipe and heat exchanger is communicated with; Water valve is arranged on cold water inlet; Cold water inlet is connected with a cold water water supply connector, and hot water outlet pipe is connected with water out adapter.Existing problems are: in the winter time, temperature is low, remain in the water freezing of heat exchanger and cold water inlet, and make heat exchanger and cold water water inlet explosion.
Summary of the invention
