Abstract
The utility model relates to a controller for a water valve automatic control exhaust fan of a water heater, which mainly solves the problem of inconvenient use. The utility model is characterized in that cams are fixed to a connecting rod; the cams are fixed to an air valve axis of an air valve of the water heater at one end of the water valve of the water heater through the connecting rod; the cams push a key of a micro-operation switch; the micro-operation switch is fixed to a valve body of an air valve of the water heater; the micro-operation switch is connected with power supply of the exhaust fan. The utility model is applied to a gas water heater.
Description
The utility model relates to the control device that a kind of water heater water valve is controlled ventilating fan automatically.
In prior art, the discharging of waste gas of water heater adopts exhaust duct to stretch out the open air, because EGT is than higher, so waste gas can be discharged the open air with comparalive ease, but sometimes under the influence of wind, make waste gas be easy to flow backwards, thereby it is indoor that waste gas is trapped in, and influences the healthy of people, and ventilating fan indoors is installed again, forget unlatching during use easily, use inconvenient.
The purpose of this utility model provides the control device that a kind of water heater water valve easy to use is controlled ventilating fan automatically.
The utility model is made up of water heater water valve, water heater air valve, microswitch, it is characterized in that: cam is fixed on the connecting rod, cam is fixed on by connecting rod on the valve shaft of water heater air valve of water heater water valve one end, cam withstands on the button of microswitch, microswitch is fixed on the valve body of water heater air valve, and microswitch links to each other with the power supply of ventilating fan.
Because the utility model cam is fixed on the connecting rod, cam is fixed on the water heater valve shaft of water heater water valve one end by connecting rod, cam withstands on the button of microswitch, microswitch is fixed on the valve body of water heater air valve, microswitch links to each other with the power supply of ventilating fan, during use, opening the water source makes the water valve axle of water heater water valve back down valve shaft, the water heater valve shaft drives cam and moves, cam makes the button pressed of microswitch, thereby microswitch is connected and is opened ventilating fan, when closing the water source, the water valve axle of water heater water valve moves after under the effect of spring and drives valve shaft, the water heater valve shaft moves after driving cam, thereby microswitch is disconnected and closes ventilating fan, so easy to use, under the effect of ventilating fan, waste gas can not flow backwards.
Below in conjunction with accompanying drawing the utility model is elaborated,
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the circuit theory diagrams of the utility model control ventilating fan,
1 expression cam among the figure, cam is fixed on the connecting rod 2, cam is fixed on by connecting rod on the valve shaft 5 of water heater air valve 4 of water heater water valve 3 one ends, cam withstands on the button 7 of microswitch 6, microswitch is fixed on the valve body of water heater air valve, in order to prevent the microswitch electric leakage, power supply links to each other with microswitch by reducing transformer B1, microswitch links to each other with relay J 1 by diode D1, power supply links to each other with ventilating fan 8 by the main contacts J1-1 of relay J 1, microswitch is connected and is made relay J 1 adhesive, drive the main contacts J1-1 closure of relay J 1, thereby connection ventilating fan, microswitch disconnect the main contacts J1-1 that makes relay J 1 and disconnect, thereby close ventilating fan.
The utility model is applicable to gas heater.
