Description
The utility model relates to a kind of no gas poisoning type gas heater.
Gas heater has been the widely used a kind of living utensil of China town dweller.Yet because improper use and product protection function are imperfect; cause anthracemia casualty accident (being commonly called as gas poisoning) to happen occasionally; and along with the rising year by year of water heater popularity rate; gas poisoning becomes worse, thereby becomes a problem of society and users' growing interest.What kind of gas heater can be stopped the gas poisoning in the gas heater use, is the crucial difficult problem in whole society's concern and this technical field.
Fuel gas buring is the groundwork form of water heater, and burning needs oxygen, consumes oxygen.If supply with the hypoxgia of burning, fuel gas buring will form imperfect combustion and generate carbonic oxide gas.The accumulation result of indoor carbonic oxide gas causes the people of indoor bathing or not bathing to poison, even dead.Long-term next social serious hope can have a kind of no toxic type gas heater to be born.
Task of the present utility model is to solve above-mentioned public and social interest and propose a kind of no toxic type gas heater that can guarantee can not take place in the gas heater use carbonic oxide intoxicating phenomenon, to stop carbonic oxide intoxication accident in the gas heater use, ensure the healthy and safe of water heater end user and indoor occupant.
The technical solution of the utility model is: a kind of no gas poisoning type gas heater, form by water tank, burner, aqueous vapor valve, ignition controller, working power, working power is a kind of control power supply, the control power supply is controlled by compound ventilation air-changing device, compound ventilation air-changing device is as the load control piece in the control power circuit, control structure is: load running control power supply output services voltage, power to water heater, the load control piece cuts off and does not turn round, control power supply no-output, stop to the water heater power supply, gas heater is flame-out.
The working power of traditional gas heater is a battery, because the technical solution of the utility model, the working power of gas heater is changed over the control power supply, control power circuit in compound ventilation air-changing device as the load control piece, make gas heater and compound ventilation air-changing device run-in synchronism, guaranteed the room air circulation like this, waste gas is discharged, indoor have sufficient oxygen, guarantee the combustion gas normal combustion, can not stop the generation of carbonic oxide gas because of carbonic oxide gas appears in anoxic, guarantee that no gas poisoning phenomenon takes place, and finishes the invention task.
Fig. 1 is the gas heater structure chart.
Fig. 2 is control circuit construction of electric power embodiment.
Fig. 3 is control power circuit principle figure.
Be described in detail the utility model below in conjunction with accompanying drawing.
A kind of no gas poisoning type gas heater, by water tank (1), burner (2), water vapor valve (3), ignition controller (4), working power (5) is formed, it is characterized in that working power is a kind of control power supply (5), control power supply (5) is subjected to compound ventilation air-changing device (6) control, compound ventilation air-changing device (6) is as the load control piece (G) in control power supply (5) circuit, control structure is: load running control power supply (5) output services voltage, power to water heater, load cuts off and does not turn round, control power supply no-output, stop to water heater power supply gas heater stop working (Fig. 1 .2.3).
The compound ventilation air-changing device of no toxic type gas heater (6) can be general ventilating fan for kitchen use, also can be generally to reach the equipment that indoor-outdoor air is exchanged.
Control power supply (5) circuit of no toxic type gas heater is partly formed (Fig. 2) by transformation rectification circuit (11), on-off circuit (12), control circuit (14) three.
Transformation rectification circuit (11) in control power supply (5) circuit of no toxic type gas heater is by transformer L1, bridge rectifier D 1, one end of rectifier output end is directly exported, the other end enters on-off circuit (12), export through on-off circuit, on-off circuit (12) is made up of triode S1, S2, and it is elementary that control circuit (4) seals in transformer L2 by compound ventilation air-changing device (6) as load control piece G, and L2 level exports triode S1 base stage in the on-off circuit (12) to through rectifier D2.
Control power circuit (5) can be contained in the box, the box face is established a release knob, with the release knob operation, and simultaneously operating water heater and compound ventilation air-changing device running, the control power supply can be connected with water heater bottom electric source connecting box (7), also can directly be fixed on the water heater.So the utility model water heater can guarantee safe handling.
For guaranteeing that circuit output end has stable voltage, can have voltage-stabiliser tube D3 between two outputs.Can have among rectifier D1, the D2 to absorb capacitor C 1, the C2 that exchanges, resistance R and diode D5 also can be set in D1.Rectifier D1, D2 can be the bridge rectifiers that is made of four diodes, can be half-bridges also, are far more than it is to be made of a diode.
On-off circuit is by triode S1, S2 forms, and when compound ventilation air-changing device (6) work, load G is arranged in the circuit, L2 time level has voltage, through rectifier D1, the S1 base stage has voltage, the S1 colelctor electrode, the emitter stage conducting, the S1 colelctor electrode links to each other with the S2 base stage, the S2 base stage has voltage, emitter stage conducting, circuit output end (13) output voltage, the gas heater operate as normal, otherwise, when compound ventilation air-changing device (6) is not worked or malfunctioning quitting work, the elementary no-voltage of transformer L2, inferior utmost point no-output, the S1 base stage does not have electricity, and not conducting of S2 is and ends, circuit output end (13) no-output, gas heater quits work.
Owing to adopt the control power supply, the control power supply is subjected to compound ventilation air-changing device control and gas heater run-in synchronism again, guaranteed gas heater environment for use well-ventilated, anoxic in can generation chamber and cause producing carbonic oxide gas, compound ventilation air-changing device can be generally to make indoor-outdoor air reach the equipment of circulation, also similar equipment is stopped the combustion gas intoxicating phenomenon thus.
The utility model has the advantage of benefiting society, ensureing health.
