The door switch is connected with circuit board by electric wire.
The circuit board is connected with tractor by draught line.
Preloading spring is provided between two contiguous blocks, to being played a protective role during tractor tension hard wire.
The guiding circular arc overlaps with the center of circle of hinge pin for door.
The stone dead wire is provided with one section of steel wire spiral, and it can prevent stone dead wire from releasing, and steel wire spiral is drawn after stress
Directly, stress can recover spiral-shaped automatically after disappearing.
Described touching lever can be pressed under external force towards the sealing strip being provided between refrigerator doors and refrigerator body, touching lever
Inside door switch；When cancelling external force effect, touching lever can eject from door switch.
The touching lever is provided with infrared sensor, and for detecting the state of refrigerator doors, if detecting, refrigerator doors are not turned off, red
The enabling information detected can be delivered on circuit board by outer sensor by door switch, and then control circuit starts tractor,
Refrigerator doors are driven to close.
Described guiding circular arc, the constant of torque in door closing procedure can be kept.
Described fixing point makes guiding circular arc be connected with stone dead wire.
The guide groove being provided with the guiding circular arc, steel wire spiral can be coordinated, to prevent stone dead wire from deviating from.
The tractor is motor or cylinder, can control hauling speed so that refrigerator doors are slowly shut, and are prevented fast
To refrigerator doors or the shock degree of refrigerator body when speed is closed, safety coefficient is improved.
Compared with prior art, the invention has the advantages that：
Whether the design of the invention is scientific and reasonable, simple in construction, effectively automatic detection refrigerator doors can close or close tight, and automatically
Door is closed, effectively prevents food spoilage, prevents refrigerator frosting from condensing, ensure that the health of the fresh and people of food,
Energy-saving safe.

Embodiment
With reference to embodiment, the present invention is further illustrated, but it is not intended to limit the implementation of the present invention.
Embodiment 1
As Figure 1-4, the door engine of the refrigerator, including door switch 3, circuit board 6 and tractor 8, Men Kai
3 one end for being located at refrigerator body 10 are closed, the end of door switch 3 is provided with touching lever 2；Circuit board 6 is provided with buzzer 5；Tractor 8 with
Hard wire 9, contiguous block 11 and stone dead wire 14 are sequentially connected；Guiding circular arc 17 is provided with close to the top of refrigerator doors 1 of hinge pin for door 15,
Guide groove 18 is provided with guiding circular arc 17, is provided with fixing point 16 in guide groove 18, fixing point 16 is connected with stone dead wire 14.
The door switch 3 is connected with circuit board 6 by electric wire 4.
The circuit board 6 is connected with tractor 8 by draught line 7.
Preloading spring 12 is provided between described two contiguous blocks 11, to being played during the tension hard wire 9 of tractor 8
Protective effect.
The guiding circular arc 17 overlaps with the center of circle of hinge pin for door 15.
The stone dead wire 14 is provided with one section of steel wire spiral 13, and it can prevent stone dead wire 14 from releasing, steel wire spiral shell after stress
Rotation 13 is straightened, and stress can recover spiral-shaped automatically after disappearing.
Described touching lever 2 can be used towards the sealing strip being provided between refrigerator doors 1 and refrigerator body 10, touching lever 2 in outer masterpiece
It is pushed down into inside door switch 3；When cancelling external force effect, touching lever 2 can 3 ejection from door switch.
The touching lever 2 is provided with infrared sensor, and for detecting the state of refrigerator doors 1, if detecting, refrigerator doors 1 are not closed
Close, the enabling information detected can be delivered on circuit board 6 by infrared sensor by door switch 3, and then control circuit starts
Tractor 8, refrigerator doors 1 are driven to close.
Described guiding circular arc 17, the constant of torque in door closing procedure can be kept.
