Abstract
The utility model relates to an interlock device for the press keys of range hoods, which includes a microcontroller and is characterized in that the four press keys of a mechanical control range hood are changed into four light touch press keys. One end of the four light press keys is connected with the input end of the microcontroller and is connected with the cathode of a power supply through a resistor. The public end of the four light touch keys is earthed. The output end of the microcontroller is connected with a luminescent tube. The interlock device for the press keys of range hoods has the beneficial effects that the interlock of the strong press keys of a fan motor and the weak press keys of the fan motor are ensured through the control of the microcontroller and the short circuit of the power supply and the motor damage can not be caused. Every press key is equipped with an indicator light which brings convenience to use. The interlock device is used for the replacement of the four press keys of the common mechanical control range hood.
Description
Technical field
The utility model relates to a kind of interlock of button, particularly a kind of interlock of standard machinery formula control range hood button.
Background technology
The utility model is before the applying date, and standard machinery formula control range hood has the fourth gear button, i.e. the weak shelves button of the prime time button of mains switch button, illumination button, fan electromotor and fan electromotor.Because in the design, the weak shelves button of the prime time button of fan electromotor and fan electromotor can not be guaranteed interlocking, when pressing at the same time, then causes power supply short circuit, damages motor.Standard machinery formula range hood does not have the button indicator light in addition, makes troubles to use.
Summary of the invention
The purpose of this utility model provides a kind of interlock with range hood button of button indicator light.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises single-chip microcomputer.。It is characterized in that changing the fourth gear button that mechanical type controls range hood into four touches button, four ends that touch button are connected with the single-chip microcomputer input, and are connected its common end grounding with positive source by resistance.The single-chip microcomputer output is connected with luminous tube.
The beneficial effects of the utility model are to guarantee interlocking between the weak shelves button of the prime time button of fan electromotor and fan electromotor when pressing at the same time, can not cause power supply short circuit by Single-chip Controlling, damage motor.Each button is equipped with indicator light, brings convenience to use.The utility model is used for the replacement of standard machinery formula control range hood fourth gear button.
Description of drawings
The utility model is described in further detail below by accompanying drawing.
Accompanying drawing 1 is an electrical schematic diagram of the present utility model.
Embodiment
