Abstract
The utility model discloses an automatic electromagnetic door opener. An iron core made of pure iron can be pushed by the electromagnetic action, a push rod is driven to open a door body, the generation of the electromagnetic field is controlled by a light touch switch, and thereby, the utility model can realize that the door can be automatically opened. The utility model has the advantages of convenience and labor saving. The door can be easily opened under various conditions that the door can not be conveniently opened by hand. The utility model can be widely used for domestic electric appliances such as a refrigerator, a freezer, a show cabinet, etc.
Description
The utility model relates to a kind of automatic door operator, and more particularly a kind of electromagnetic action that adopts is realized the device that household electrical appliances open the door automatically.
Present household electrical appliances mostly are and pull a design, and there is following shortcoming in it: when opening the door, make the comparatively effort of opening the door owing to Men Titai is heavy 1.; 2. when both hands all take thing to look on the bright side of things door, inconvenient down thing, do not put down thing and do not use power again; 3. wet, stick greasy dirt when dirtier, the inconvenience of opening the door when both hands.
The purpose of this utility model is the weak point of avoiding above-mentioned to provide a kind of electromagnetic type automatic door operator, make open the door laborsaving, convenient, cleaning and again opposite house body itself do not influence.
The technical solution of the utility model is such: it promotes the iron core that a pure iron is made by electromagnetic action, drives a push rod door body is opened, and the generation of electromagnetic field is controlled by a touch-switch, thereby realizes opening the door automatically.The utility model comprises a coil windings, in order to generate an electromagnetic field the iron core that a pure iron is made and the push rod that is attached thereto, the spring that is used for resetting and a touch-switch.When touching touch-switch, power connection, coil electricity, thus generating an electromagnetic field, the magnetic force of electromagnetic field promotes iron core forward, and the drive push rod backs down the door body.After opening the door, touch-switch automatically resets, dump, and magnetic field diminishes, iron core is homing under the effect of back-moving spring, thereby finishes the action of once opening the door.
The utility model has the advantages that conveniently, laborsaving, can various be inconvenient to use under the situation about pulling at an easy rate door is opened, be widely applicable in the household electrical appliances such as refrigerator, refrigerator, showcase.
Further specify the utility model below in conjunction with accompanying drawing and by embodiment.
Fig. 1 is an electrical schematic diagram of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is that the utility model assembles schematic diagram on the door body.
As Fig. 1, shown in Figure 3, the utility model comprises touch-switch 12, power supply 11, automatic top opening 13, and opposite house body 14 backs down operation automatically.
Wherein, top opening 13 comprises a housing 16, coil windings 5, iron core 6, skeleton 3, push rod 2, push rod cup 1, copper ring 4, back-moving spring 7, stop component 8 and cushioning fender 9 automatically.Skeleton 3 is one columnar structured, above coil 5 just is wrapped in.Iron core 6 is a cylinder, is made by pure iron, has good electromagnetic property, and does not have remanent magnetism after the outage; There is the stop component 8 of slightly larger in diameter at the rear portion of iron core 6.Copper ring 4 is made cylindric by a scale copper, be close to the inner surface of skeleton 3, reduces the frictional force of contact surface.Push rod 2 is an elongated stainless steel, makes one with iron core 6, relies on it to release forward door is pushed open, and its stroke is not less than 20 millimeters.Cushioning fender 9 makes its rebound become comparatively mild.Push rod cup 1 be mainly used in increase with a body between active area and cushioning accordingly, reduce the impact of opposite house body.
Touch-switch 12 is a linkage from top to bottom formula structure, and touching two positions of upper and lower faces all can be with power connection, touches and finishes back (hand leave switch after), and touch-switch can automatically reset, and power supply is disconnected.
Also comprise fuse 10 in circuit, it mainly plays overload, overvoltage protection effect, and when electric current was excessive, blown fuse protected whole device to be without prejudice.
As shown in Figure 3, touch-switch 12 places on the body 14, and automatically top opening 13 places the end away from door-hinge 15, with increase opplied moment, make open the door more reliable laborsaving.
When touching touch-switch 12, power supply 11 is connected, and the coil 5 after the energising produces more intense electromagnetic field, and the magnetic force that electromagnetic field produces sucks iron core, and promotes push rod 2 and release fast forward, and the door body of front is backed down.After the door body backed down, touch-switch 12 automatically reset, and power supply 11 disconnects, and electric current is zero in the coil 5, magnetic field diminishes, and the suction to iron core 6 disappears simultaneously, and iron core 6 is homing under the effect of back-moving spring 7.
Claims (4)
1. electromagnetic type automatic door operator, it comprises touch-switch (12) and power supply (11), it is characterized in that it also comprises an automatic top opening (13).
2. electromagnetic type automatic door operator according to claim 1 is characterized in that also comprising in the circuit fuse (10).
3. electromagnetic type automatic door operator according to claim 1 is characterized in that wherein said automatic top opening (13) comprises a housing (16), coil windings (5), iron core (6), skeleton (3), push rod (2), copper ring (4), back-moving spring (7), stop component (8) and cushioning fender (9).
