Abstract
A pedal-type refrigerator which automatically opens door comprises an electromagnetic automatic door opener of control circuit, and a refrigerator with a microprocessor. The utility model is characterized in that the bottom of the refrigerator is provided with a pedal-type switch, two ends of which are respectively connected with the input end of the microprocessor and the end of an electric resistance R<2> by a connecting line; the control circuit is connected with a crystal triode base by the output end of the microprocessor passing through the electric resistance R<2>; the emitter degeneration is close to the ground; the collector outputs to the control automatic opener relay. The utility model is more labor-saving and convenient than human hands.
Description
The utility model relates to a kind of foot-operated refrigerator with automatically openable door.
The existing manual soft-touch type that utilizes the electromagnetic type automatic door operator refrigerator that opens the door, touch switch inconvenience when both hands are held full thing, and child of short and small stature touches less than switch and opens the door.
The objective of the invention is to be to overcome above-mentioned deficiency, a kind of laborsaving foot-operated easily refrigerator with automatically openable door is provided.
The utility model is on the basis of existing manual soft-touch type refrigerator with automatically openable door, utilize its existing electromagnetic type automatic door operator, manual touch-switch that only will be wherein is with floor push and be controlled by microprocessor MCU and the electronic switch replacement of transistor of break-make and relay forms;
Above-mentioned the utility model of constructing is obviously than more laborsaving with hand, convenient.
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 the utility model assembling schematic diagram.
Fig. 2 circuit theory diagrams of the present utility model.
As figure, the utility model comprises the electromagnetic type automatic door operator 1 that has control circuit 3, and the refrigerator 4 that comprises microprocessor MCU, and it is characterized in that being positioned at refrigerator 4 bottoms has to be a K
1Floor push 2, the two ends of floor push 2 connect microprocessor MCU input and resistance R through line 5 respectively
2With the ground end, this resistance R
2Another termination DC voltage+VCC.DC voltage+VCC is obtained by common transformation T, rectification D and mu balanced circuit W.Control circuit 3 by the output of microprocessor MCU via resistance R
1Be connected to transistor Q
1Base stage, its grounded emitter, colelctor electrode exports relay 6 to be formed, by civil power 220V through rectification circuit D
1Provide power, the coil adhesive K switch of relay 6 during conducting
2, control is arranged on the automatic door operator 1 energising action on the refrigerator 4, and promptly foot-operated enabling signal is confirmed back output signal control transistor Q conducting through microprocessor MCU, thus realizing that refrigerator is ridden opens the door automatically.
