Abstract
The utility model discloses an exhauster for a miniature full-automatic gas water heater, which is composed of an interface with a big and a small heads (1), a miniature thin soft tube (2), an exhaust blower (3), an air-sensitive probe (4), and a switch control circuit (5). The utility model is characterized in that due to the tiny diameter of an exhaust pipe, only a small hole needs to be opened in a wall or the glass of a window when the utility model is arranged; furthermore, due to the adoption of the forced exhaust carried out by the exhaust blower, the effect of the smoke exhaust is good and smoke is prevented from returning. The utility model has the advantages of convenient installation, space saving, and no influence on the beauty of houses.
Description
The utility model relates to a kind of exhaust apparatus of gas heater.
At present, the exhaust apparatus of gas and hot water gas mostly adopts the blast pipe identical with smoke bore on the gas heater to carry out smoke discharging in the prior art, the shortcoming of this blast pipe is that diameter is big, institute takes up space big, influence the attractive in appearance of house, and difficulty is installed, because port of export bore is too big, be easy to generate down cigarette, influence normal exhaust.
The purpose of this utility model is: little, the easy installation of a kind of blast pipe diameter, good exhaust effect are provided, are difficult for producing the miniature full-automatic gas-fired water heater exhaust apparatus of cigarette.
The utility model is to constitute like this: it is by concentric reducer interface (1), miniature small hose (2), scavenger fan (3), gas-sensing probe (4), ON-OFF control circuit (5) is formed, the big opening end of concentric reducer interface (1) can be fastened on the exhaust smoke outlet of gas heater, one end of miniature small hose (2) is fastened on the osculum end of concentric reducer interface (1), scavenger fan (3) is contained on the another port of miniature small hose (2), gas-sensing probe (4) is installed on the gas heater, on-off circuit (5) is by transformer, rectification circuit, TWH8778 switch integrated package, resistance R 1～R3, and 470u and two electric capacity compositions of 100u, the inferior utmost point of transformer connects the input of rectification circuit, the negative pole of output end of rectification circuit connects negative pole and 4 pin of switch integrated package and the negative terminals of scavenger fan (3) of the negative pole and the gas-sensing probe (4) of electric capacity, the output cathode of rectification circuit connects the positive pole of 470u electric capacity and the end of R1, the positive pole and the R2 of another termination 100u electric capacity of R1, the end of R3 and 1 pin of switch integrated package, R2, the other end of R3 connects the positive pole of gas-sensing probe (4) respectively, 5 pin of the adjusting termination switch integrated package of R3,2 of switch integrated package, the run in positive terminal of gas fan (3) of 3 pin.
The utility model compared with prior art because the blast pipe diameter is little, only needs on the wall during installation or an aperture of opening on glass of window can be installed, thus install very easy, and take up space little, do not influence the attractive in appearance of house; In addition owing to adopted scavenger fan to carry out exhaust by force, so good exhaust effect, can not produce down cigarette.During use, the attaching plug of ON-OFF control circuit (5) is inserted on the AC Power supply socket gets final product, if at this moment use gas heater, the resistance change of gas-sensing probe (4), ON-OFF control circuit (5) conducting automatically, scavenger fan (3) work carrying out exhaust; When stopping using gas heater, gas-sensing probe (4) recovers normal value, and ON-OFF control circuit (5) automatically shuts down, and scavenger fan (3) outage quits work.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is circuit theory diagrams of the present utility model.
Embodiment of the present utility model: concentric reducer interface (1) adopts metal material to make, miniature small hose (2) employing diameter is that 2 centimeters metal hose is made, scavenger fan (3) adopts the finished product of selling on the market, it is HQ-1 that gas-sensing probe (4) adopts its model of finished product of selling on the market, it is the switch integrated package of TWH8778 that switch element in the ON-OFF control circuit (5) adopts model, the big opening end of concentric reducer interface (1) is fastened on the exhaust smoke outlet of gas heater, one end of miniature small hose (2) is fastened on the osculum end of concentric reducer interface (1), scavenger fan (3) is contained on the another port of miniature small hose (2), gas-sensing probe (4) is installed on the gas heater, on-off circuit (5) is by transformer, rectification circuit, TWH8778 switch integrated package, resistance R 1～R3, and 470u and two electric capacity compositions of 100u, the transformer of transformer adopting 220V:9V, the inferior utmost point of transformer connects the input of rectification circuit, the negative pole of output end of rectification circuit connects negative pole and 4 pin of switch integrated package and the negative terminals of scavenger fan (3) of the negative pole and the gas-sensing probe (4) of electric capacity, the output cathode of rectification circuit connects the positive pole of 470u electric capacity and the end of R1, the positive pole and the R2 of another termination 100u electric capacity of R1, the end of R3 and 1 pin of switch integrated package, R2, the other end of R3 connects the positive pole of gas-sensing probe (4) respectively, 5 pin of the adjusting termination switch integrated package of R3,2 of switch integrated package, the run in positive terminal of gas fan (3) of 3 pin.
