Abstract

A water temperature adjustment controller of combustion gas water heater relates to the application of electromechanical integration in domestic combustion gas water heater, for resolving the problems of prior combustion gas water heater which should be mounted outside bathroom, while water temperature adjustment is processed outside bathroom and user is hard to adjust water temperature in bath, with low water temperature adjustment accuracy. The technical scheme of the utility model comprises that uses a touch-switch to generate an electric pulse via a RC trigger shock-removal shaping circuit to be fed into a step motor driver to generate a phase pulse signal of step motor, to operate the step motor, to rotate a fire adjusting valve, thereby adjusting water temperature in bathroom. The utility model is mainly used for remotely controlling water temperature of combustion gas water heater at high accuracy or for the control of button with high accuracy demand.

Summary of the invention

Shower person is in the water temperature of bathroom inner control gas heater for convenience, on the basis of existing gas heater, increase water temperature adjustment control in the gas heater bathroom, shower person regulates the rotation of the flame regulating valve door of gas heater by the mode of button in the bathroom, thereby reach the purpose of regulating water temperature in the bathroom.The technical scheme that its technical problem that solves the utility model adopts is: water temperature rising touch-switch K2 and water temperature decline touch-switch K1 are respectively the inputs that rest-set flip-flop removes to tremble shaping circuit, NAND gate G1, the output of G3 links to each other with the pulse signal negative pole (CP-) of stepper motor driver behind nor gate G5, the output of NAND gate G4 links to each other with the direction control signal negative pole (CW-) of stepper motor driver, the phase current output terminals A of stepper motor driver+, A-, B+, B-is respectively with the A phase of stepping motor, B phase both positive and negative polarity links to each other, be fixed with driven wheel in the rotating shaft of stepper motor, be fixed with travelling gear and flame regulating valve door knob in the rotating shaft of flame regulating valve door, the travelling gear of the driven wheel of stepper motor and flame regulating valve door matches.

Be fixed with two shape of triangular ridges respectively in the inboard of travelling gear, 2. and 4. the mouse microswitch is housed in the both sides of flame regulating valve door, the negative pole of a mouse microswitch termination power 2., the negative pole of another termination LED1, the positive pole of LED1 connects+the 5V power supply, the negative pole of a mouse microswitch termination power 4., the negative pole of another termination LED2, the positive pole of LED2 connect+the 5V power supply.

The beneficial effects of the utility model are: the water temperature that the user can remote, high-precision adjusting gas heater by touch-switch in the bathroom, rotation to the flame regulating valve door has spacing indicative function, do not need existing water heater is done bigger change, can also be used for the control of other knob.
