Description
Technical field
The utility model relates to fluid heater field, relates in particular to a kind of gas instantaneous water heater automatic drainage freeze preventer.
Background technology
Gas heater, because firepower is called fast water heater soon compared with violent, firing rate, is mainly used in disperseing with water spot, and water consumption is less, and the water time is short, and comfortableness requires high place, as the independent toilet at family, small-sized hostel etc.
Common combustion gas fast type water heater mainly comprises: burner, heat exchanger, the parts such as inlet tube and outlet tube and safety device.After use, in heat exchanger, all tend to retain the water of having a surplus.Thereby, in some colder areas, the north, for preventing bursting by freezing water heater, after disposable gas fast type water heater, all need manually to carry out water-drainage antifreezing operation, to avoid the spalling of enduring cold of the water pipe of heat exchanger.But the antifreeze operation of this manual drainage not only brings very big inconvenience to use, and easily due to carelessness draining and freezing water heater.
Summary of the invention
For the defect existing in prior art, it is a kind of simple in structure that the purpose of this utility model is to provide, the automatic drainage freeze preventer of effectively avoiding heat exchanger water pipe to be split up.
For reaching above object, the utility model adopts following technical scheme.
A kind of gas instantaneous water heater automatic drainage freeze preventer, is characterized in that, comprising: air intake control valve, draining control valve, inductor and controller;
On heat exchanger pipeline, be provided with air inlet and discharge outlet, described air intake control valve is arranged on air inlet, described draining control valve is arranged in discharge outlet, and described inductor is arranged on heat exchanger pipeline, and described controller is connected with inductor, draining control valve.
As further illustrating of such scheme, described air intake control valve is the check valve that is arranged on the bend pipe the top of heat exchanger pipeline.
As further illustrating of such scheme, described inductor is to extend into the temp probe in heat exchanger pipeline through the tube wall of heat exchanger pipeline, or is close to the temperature inductor of heat exchanger tube wall surface.
As further illustrating of such scheme, described draining control valve is the Electrocontrolled tee valve that is arranged on heat exchanger pipeline water inlet end.
As further illustrating of such scheme, described discharge outlet is arranged on the water inlet end of heat exchanger pipeline, water inlet end is inverted T-shaped pipe, and two of inverted T-shaped pipe is respectively water inlet and discharge outlet, and described draining control valve is two magnetic valves that are arranged on respectively in water inlet and discharge outlet.
As further illustrating of such scheme, described air intake control valve and draining control valve are all electric T-shaped valve, and two electric T-shaped valves are separately positioned on water inlet end and the water side of heat exchanger pipeline.
Compared with prior art, the utility model is by being located at the water temperature inductor in heat exchanger pipeline, sense when water temperature in heat exchanger tube drops to uniform temperature, automatically open air intake control valve and draining control valve, the water that heat exchanger pipeline inner product is deposited drains into outside water heater smoothly by draining control valve, prevents the water pipe from freezing crack of heat exchanger.

Detailed description of the invention
For further setting forth essence of the present utility model, by reference to the accompanying drawings detailed description of the invention of the present utility model is described as follows.
Embodiment mono-
As shown in Figure 1 and Figure 2, a kind of gas instantaneous water heater automatic drainage freeze preventer, comprising: be arranged on check valve 2, Electrocontrolled tee valve 3 on heat exchanger pipeline 1, inductor 4, and with the controller 5 of Electrocontrolled tee valve 3 and inductor 4 control connections.
Wherein, described check valve 2 is arranged on the bend pipe the top of heat exchanger pipeline 1, is communicated with atmosphere.Described Electrocontrolled tee valve 3 is arranged on the water inlet end 11 of heat exchanger pipeline 1, is communicated with water inlet 12 and discharge outlet 13.Described inductor 4 is for to extend into the temp probe in heat exchanger pipeline 1 through the tube wall of heat exchanger pipeline 1, so that water temperature in accurate induction tube.
In the time that water temperature does not drop to solidification point, water heater is Fig. 1 situation, check valve 2 under Water Pressure in the situation of closing.In the time that inductor 4 detects that water temperature drops to solidification point, provide signal by controller 5, Electrocontrolled tee valve 3 is switched, block water inlet 12, open the discharge outlet 13 of bypass line simultaneously, hydraulic pressure in heat exchanger pipeline 1 declines, and check valve 2 is opened, and air enters in pipe, water in heat exchanger flows out by discharge outlet 13, make the water that accumulates in heat exchanger pipeline 1 emptying, prevent heat exchanger bursting by freezing, see Fig. 2.When inductor 5 detect water temperature rise to not can bursting by freezing temperature time, Electrocontrolled tee valve 3 resets, water route is returned to Fig. 1 situation, water heater can normally be worked.
Embodiment bis-
As shown in Figure 3, a kind of gas instantaneous water heater automatic drainage freeze preventer, comprising: be arranged on the Electrocontrolled tee valve 3 on heat exchanger pipeline 1, inductor 4, and with the controller of Electrocontrolled tee valve 3 and inductor 4 control connections.
A kind of gas instantaneous water heater automatic drainage freeze preventer that the present embodiment provides, its structure and embodiment mono-are basically identical, difference is: cancelled check valve, Electrocontrolled tee valve 3 changes two into, is separately positioned on the water inlet end 11 and water side 14 of heat exchanger pipeline 1.Controlled respectively by controller, discharge the water in heat exchanger pipeline 1, play the function of anti-freeze.
