The specific embodiment
Below in conjunction with the drawings and specific embodiments, combined hinge for electric refrigerator of the present invention is described in further detail:
In following embodiment, omit explanation for identical in the past part.
As Fig. 4, shown in Figure 5, the combined hinge structure of the present invention's design is made of chamber door hinge 12 that is fixed on the chamber door rear end and the chest hinge 14 that is fixed on casing 2 back.Chamber door hinge 12 and chest hinge 14 are that the center can be rotated with hinge axis 13.
Downside at chamber door hinge 12 is provided with strip support portion 12a, and it is identical with traditional approach in fact at the downside of strip support portion 12a the structure of support bar 16 to be set.And the structure that spring 18 is set at the packing ring 16a of support bar 16 cores downside is also identical with traditional approach.
Here, the course of action to the support bar 16 relevant with the switch chamber door describes.Side view when the side view when Fig. 4 represents that chamber door is closed, Fig. 5 represent that chamber door is opened.Strip support portion 12a is contained in the groove of support bar 16 upper ends formation.At this moment, the holding power on support bar 16 tops is elastic restoring forces of spring 18.And as Fig. 4 and shown in Figure 5, under the chamber door closing state, when opening chamber door, chamber door hinge 12 is that the center is by counterclockwise rotating with hinge axis 13.
At this moment, under support bar 16 is supported by spring 18 in its underpart, do seesawing (being side-to-side movement among the figure) and moving up and down.This move up and down and seesaw just be readily appreciated that with reference to Fig. 4 and Fig. 5.And the front and back of this support bar 16 and the motive power that moves up and down are the elastic forces of spring.
The present invention is with except spring 18, and also having possessed another damping structure is essential characteristic.This another damping structure comes down to utilize frictional force, and frictional force is carried out front and back by support bar 16 and provide when moving up and down.
Below, another damping structure of the present invention is described.
By Fig. 4, Fig. 5 and Fig. 6 as can be known, the spring lower end supported by base 50, as shown in Figure 5, the base 50 of the present invention's design is in order to support the lower end of spring 18, possessed to prolong the flange 54 that forms to the periphery, and formed frictional groove 52 at its length direction.
In illustrated embodiment, the section of frictional groove 52 is identical with the section of support bar 16 lower ends, all is quadrangle.But the section configuration to frictional groove 52 has no particular limits, as long as produce friction when support bar 16 is done front and back and moved up and down, the section configuration that can play damping action can adopt.
And, be provided with the support piece 46 of supporting base 50 in the lower end of base 50.Support that piece 46 is fixed on the chest hinge 14.And, also can support piece 46 on chest hinge 14, to be mounted to and can't to move up and down, and form the rotating structure of certain angle with chest hinge.
