Description
Technical field
The utility model relates to a kind of household electrical appliance for kitchen use, particularly relates to a kind of smoke exhaust ventilator with automatic cleaning function.
Background technology
Smoke exhaust ventilator is a kind of kitchen appliance that purifies kitchen environment.It is installed in kitchen health energy-saving range hood cooking stove top, the harmful oil smoke that produces in the refuse of cooking stove burning and the cooking process can be taken away rapidly, discharges outdoorly, reduces pollution, purifies air, and gas defence, explosion-proof safety guarantee effect are arranged.
Smoke exhaust ventilator has become the requisite cooking apparatus of Modern Family.The time that smoke exhaust ventilator enters Chinese average family kitchen also is not very long.Early stage family kitchen smoke evacuation work is all finished by ventilating fan.Although ventilating fan can exclude the most of oil smoke in the kitchen, the oil smoke that it produces in the unable solution culinary art is to the pollution in whole kitchen.The oil smoke that produces in the culinary art contains a lot of harmful materials, if the people works in being full of the room of oil smoke for a long time, can cause the generation of a lot of diseases.
But most of smoke exhaust ventilator does not have automatic cleaning action in the market, and manual cleaning is difficult, and easily injures skin, and some oil networks are sharp-pointed, and are easily injured, and the cleaning effort is time-consuming.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of smoke exhaust ventilator with automatic cleaning function is provided, and automatically cleans up neatly, and is easy to operate, saved the time, improved efficient.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of smoke exhaust ventilator comprises motor, drive circuit, regulator rectifier circuit, microprocessor and cleaning circuit; Output end of microprocessor connects the input of regulator rectifier circuit, and the output of regulator rectifier circuit connects the input of drive circuit, and the output of drive circuit connects the input of motor, and the output of microprocessor connects the input of cleaning circuit.The output of described microprocessor is connected with display circuit.The output of described display circuit connects LED display.
Compared with prior art, the beneficial effects of the utility model are: microprocessor feed drive signal is to regulator rectifier circuit, and regulator rectifier circuit enters drive circuit after the driving signal is carried out rectifying and voltage-stabilizing, is worked by the drive circuit drive motor; Microprocessor cleans oil smoke by cleaning circuit, and microprocessor carries display to be presented at LED display by display circuit.Automatically clean up neatly, easy to operate, saved the time, improved efficient.
Description of drawings
Fig. 1 is schematic block circuit diagram of the present utility model.
The specific embodiment
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, in order to technical characterictic of the present utility model and advantage are carried out more deep annotation.
Schematic block circuit diagram of the present utility model as shown in Figure 1, a kind of smoke exhaust ventilator with automatic cleaning function comprises motor, drive circuit, regulator rectifier circuit, microprocessor and cleaning circuit; Output end of microprocessor connects the input of regulator rectifier circuit, and the output of regulator rectifier circuit connects the input of drive circuit, and the output of drive circuit connects the input of motor, and the output of microprocessor connects the input of cleaning circuit.The output of described microprocessor is connected with display circuit.The output of described display circuit connects LED display.
Operation principle of the present utility model is as follows: microprocessor feed drive signal is to regulator rectifier circuit, and regulator rectifier circuit enters drive circuit after the driving signal is carried out rectifying and voltage-stabilizing, is worked by the drive circuit drive motor.Microprocessor cleans oil smoke by cleaning circuit, and microprocessor carries display to be presented at LED display by display circuit simultaneously.
The content of mentioning in above-described embodiment is not to be to restriction of the present utility model, and under the prerequisite that does not break away from utility model design of the present utility model, any apparent replacement is all within protection domain of the present utility model.
