Abstract
The utility model discloses a refrigerator capable of automatic opening door. A casing of an existing refrigerator is provided with an automatic pushing device, and a refrigerator door is provided with a light touch switch to replace a door handle, the automatic push device can push an iron core made of pure iron by electromagnetic action, and a push rod is driven to open the door; the generation of electromagnetic field is controlled by the light touch switch, and thereby, the automatic door opening effect of the refrigerator can be realized. The utility model has the advantages of convenience and labor saving. The refrigerator door can be automatically opened under the various conditions that the refrigerator door can not be pulled by hand conveniently.
Description
The utility model relates to a kind of refrigerator, more particularly a kind of refrigerator that utilizes electromagnetic action to realize and opening the door automatically.
Present refrigerator mostly is and pulls 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.
At the problems referred to above, the purpose of this utility model is to provide a kind of refrigerator with automatically openable door, make open the door laborsaving, convenient, cleaning and again opposite house body itself do not influence.
The utility model is that an automatic top opening is installed on the casing of existing refrigerator, and installation one touch-switch replaces door handle on refrigerator door, automatically top opening promotes the iron core that a pure iron is made by electromagnetic action, driving a push rod opens the door body, the generation of electromagnetic field is controlled by touch-switch, thereby realizes opening the door automatically of refrigerator.
The utility model has the advantages that conveniently, laborsaving, can various be inconvenient to use under the situation about pulling at an easy rate refrigerator doors is opened.
Further specify the utility model below in conjunction with accompanying drawing and by embodiment.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of automatic top opening in the utility model.
As shown in Figure 2, the utility model comprises a general refrigerator 11, it is characterized in that it also comprises touch-switch 12 and automatic top opening 13.Automatically top opening 13 is installed in the groove of opening at refrigerator body 17 tops, front of the slot has the passage of pushrod movement, touch-switch 12 replaces door handle, be installed on the refrigerator door 14, wherein, line between touch-switch 12 and the automatic top opening 13 passes through refrigerator door, and connects through the body quill shaft arrival refrigerator top of moving into one's husband's household upon marriage.Automatically top opening 13 places the end away from the refrigerator door-hinge, with increase opplied moment, make open the door more reliable laborsaving.
Automatic top opening 13 as shown in Figure 3 comprises coil windings 5, iron core 6, skeleton 3, push rod 2, push rod cup 1, copper ring 4, back-moving spring 7 and cushioning fender 9.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.
Refrigerator 11 provides a direct current power supply by a transformer for automatic top opening 13.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.
When touching touch-switch 12, power connection, 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 refrigerator 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 (3)
1. refrigerator with automatically openable door comprises a general refrigerator (11), it is characterized in that it also comprises touch-switch (12) and automatic top opening (13).
2. refrigerator with automatically openable door according to claim 1 is characterized in that wherein said automatic top opening (13) comprises 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).
3. according to claim 1 or 3 described refrigerator with automatically openable door, it is characterized in that wherein said automatic top opening (13) also comprises push rod cup (1).
