Summary of the invention
In order to overcome defects, the utility model provides the freezing protection control device of a kind of gas-heating/hot water two purpose stove with heating system, and this defroster is simple in structure, has not only avoided the combustion gas waste, also efficiently solves the phenomenon that heating system is damaged by frost.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of gas-heating/hot water two purpose stove is with the freezing protection control device of heating system, comprise body of heater shell, heating return pipe and heating hot water pipe, in described body of heater shell, the location is equipped with burner and heat exchanger, described burner is positioned the below of described heat exchanger, and heating return pipe and heating hot water pipe are communicated with by described heat exchanger; Location and installation has a water circulating pump on described heating return pipe, the location is provided with a temperature sensor on described heating hot water pipe, described temperature sensor is in order to sensing heating water leaving water temperature, and the temperature signal that senses is transferred to the master controller of dual-purpose stove, the described burner operation of described main controller controls, the keying of the described water circulating pump of described main controller controls and operate power are regulated simultaneously.
As further improvement of the utility model, described master controller is integrated with Master control chip and heat sensitive component, described Master control chip is integrated with control program controlling described gas apparatus and water circulating pump work, and described heat sensitive component is the environment temperature around it and be electrically connected on described Master control chip in order to sensing.
As further improvement of the utility model, described temperature sensor also is electrically connected on described Master control chip.
As further improvement of the utility model, also be provided with heat dissipation equipment, the delivery port of the water return outlet of described heating return pipe and described heating hot water pipe is communicated with by described heat dissipation equipment.
the beneficial effects of the utility model are: by be integrated with heat sensitive component on master controller, heat sensitive component is the environment temperature around it and be electrically connected on Master control chip in order to sensing, with the judgement precondition as the antifreeze startup of one-level, separately the location is provided with a temperature sensor on the heating hot water pipe, temperature sensor is in order to sensing heating water leaving water temperature, and the temperature signal that senses is transferred to the master controller of dual-purpose stove, with the necessary condition as the antifreeze operation of startup one-level, when above-mentioned two conditions satisfy simultaneously, Master control chip controlled circulation water pump corresponding temperature signal carries out the running of different capacity, this moment, burner need not burning, only rely on the power of water circulating pump, make the water in whole heating system be in flow regime, to reach the requirement of " flowing water does not freeze ", when temperature sensor senses to heating water leaving water temperature when being reduced to below 1 ℃, control chip control combustion device moves with minimum combustion power, heating water is heated until the antifreeze judgement of one-level is waited in the burn-out when arriving 22 ℃ of heating water leaving water temperature.This defroster is simple in structure, has not only avoided the combustion gas waste, also efficiently solves the phenomenon that heating system is damaged by frost.
Description of drawings
Fig. 1 is fundamental diagram of the present utility model;
Fig. 2 is workflow diagram of the present utility model.
By reference to the accompanying drawings, make the following instructions:
1---burner 2---water circulating pump
3---temperature sensor 4---Master control chip
5---heat sensitive component
The specific embodiment
With reference to the accompanying drawings embodiment of the present utility model is elaborated.
A kind of gas-heating described in the utility model/hot water two purpose stove freezing protection control device of heating system, comprise body of heater shell, heating return pipe and heating hot water pipe, in described body of heater shell, the location is equipped with burner 1 and heat exchanger, described burner 1 is positioned the below of described heat exchanger, and heating return pipe and heating hot water pipe are communicated with by described heat exchanger; Location and installation has a water circulating pump 2 on described heating return pipe, the location is provided with a temperature sensor 3 on described heating hot water pipe, described temperature sensor 3 is in order to sensing heating water leaving water temperature, and the temperature signal that senses is transferred to the master controller of dual-purpose stove, described burner 1 work of described main controller controls, the keying of the described water circulating pump 2 of described main controller controls and operate power are regulated simultaneously.
In the present embodiment, described master controller is integrated with Master control chip 4 and heat sensitive component 5, described Master control chip 4 is integrated with control program controlling 2 work of described gas apparatus 1 and water circulating pump, and described heat sensitive component 5 is the environment temperature around it and be electrically connected on described Master control chip 4 in order to sensing.
In the present embodiment, described temperature sensor 3 also is electrically connected on described Master control chip 4.
In the present embodiment, also be provided with heat dissipation equipment, the delivery port of the water return outlet of described heating return pipe and described heating hot water pipe is communicated with by described heat dissipation equipment.
Operation principle of the present utility model is:
One, described heat sensitive component 5 is in order to its environment temperature on every side of sensing, when the environment temperature around heat sensitive component 5 senses it drops to 4 ℃, the heat sensitive component resistance diminishes, the electric current that flows through increases, this current signal passes to Master control chip 4, as the judgement precondition of the antifreeze startup of one-level.
Two, described temperature sensor 3 in order to sensing heating water leaving water temperature, is reduced to 4 ℃ when temperature sensor 3 senses the heating water leaving water temperature, as the necessary condition that starts the antifreeze operation of one-level.
