Description
Technical field
Gas instantaneous water heater technical field is the utility model is related to, the heating more particularly, to gas instantaneous water heater is prevented
Freeze techniques.
Background technology
The existing antifreeze method of gas heater mainly has two kinds：1st, twist off draining valve manually or safety valve is drained in water heater
Water reach antifreeze purpose；2nd, low temperature is the antifreeze temperature controller of triggering, connects antifreeze calandria, and high-temperature heating body is handed over to heat indirectly
Parallel operation heating reaches antifreeze purpose.Its shortcoming is：(1) manual drainage is antifreeze easily forgets have by the risk of bursting by freezing；(2) it is antifreeze
Heating body heat content concentrates on part, and the position water temperature remote from calandria is relatively low, heats the time-consuming length of spray in whole water heater.
Name of patent application is gas heater automatic ignition heating and anti-freezing device (CN200820051746.5), openly (announces) and number is
CN201255510Y, the patent application that the applying date is 2008.08.01, it includes temperature sensing device, is mainly technically characterized by it
Also include antifreeze start-up circuit plate, described antifreeze start-up circuit plate and control circuit in temperature sensing device, gas heater
Plate and magnetic valve electrically connect.It automates antifreeze degree and still needed raising.
Utility model content
The purpose of this utility model provides a kind of by cooling-water temperature sensor monitoring heat aiming at the deficiencies in the prior art
Water temperature in hydrophone, when temperature is too low water heater start working the water in water heater is heated rapidly to certain temperature after stop work
The gas heater for the automatic heating and anti-freezing made.
In order to reach object above, the utility model patent adopts the following technical scheme that：
A kind of gas heater of automatic heating and anti-freezing, including with inlet and outlet pipe, burner, heat exchanger gas and hot water
Device main body a, it is characterised in that water return pipeline is provided between the outlet pipeline and inlet pipeline of water heater, on water return pipeline
Check valve is installed, a back water pump is installed on water return pipeline or inlet pipeline, makes water heater outlet, check valve, back water pump
Loop is connected to form, water flow sensor is provided with inlet pipeline, temperature sensor is provided with the pipeline through heat exchanger, should
Water flow sensor, temperature sensor, back water pump electrically connect with controller, when the as little as a certain temperature of water temperature, temperature sensor
The water temperature signal monitored is passed into controller, controller control backwater pump work, the water in pipeline starts to flow, water-carrying capacity
Sensor monitoring sends signal to controller, water heater is started working to water-flow signal；When temperature sensor monitors to water temperature
When reaching a certain design temperature, controller control back water pump is stopped, and does not have water flowing in pipeline, water flow sensor is anhydrous
Stream signal feeds back to controller, and water heater is stopped.
Compared with prior art, a kind of gas heater for automatic heating and anti-freezing that the utility model patent provides have with
Lower beneficial effect：
1st, automatic heating and anti-freezing when water temperature is too low；
2nd, the water in water heater can be heated to certain temperature rapidly.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Description of reference numerals：1st, check valve；2nd, return pipe；3rd, outlet pipe；4th, temperature sensor；5th, back water pump；6th, enter cold
Water pipe；7th, water flow sensor 8, heat exchanger 9, burner 10, controller.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model patent.
As shown in figure 1, a kind of gas heater of automatic heating and anti-freezing of the present utility model, including band inlet and outlet pipe
(3,4), burner 9, heat exchanger 8, the gas heater main body of controller 10, in outlet pipeline 3 and the inlet pipeline 6 of water heater
Between a water return pipeline 2 is provided with by triple valve, water flow sensor 7 is arranged on triple valve, is provided with water return pipeline 2
One back water pump 5 is installed, in the present embodiment, back water pump 5 is arranged on triple valve on check valve 1, water return pipeline 2 or inlet pipeline 6
Between heat exchanger 8, water heater outlet 3, check valve 1, back water pump 5 is connected to form loop, set on the pipeline of heat exchanger section
Temperature sensor 4 is equipped with, the water flow sensor 7, temperature sensor 4, back water pump 5 electrically connect with controller 10.
During water heater normal work, due to the pressure loss in pipeline, enter the pressure in cold water pipe more than in hot-water outlet pipe
Pressure, check valve is in cut-off state, burner normal work.
When antifreeze：When the as little as a certain temperature of water temperature, the water temperature signal monitored is passed to controller by temperature sensor, control
Device processed controls backwater pump work, and the water in pipeline starts to flow, and water flow sensor monitors water-flow signal, sends signal to
Controller, water heater are started working；When temperature sensor monitors reach a certain design temperature to water temperature, controller control backwater
Pump is stopped, and does not have water flowing in pipeline, and water flow sensor non-water flow signal feeds back to controller, and water heater stops work
Make.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.
