In addition, the lower curtate of carrying sleeve 23 can find out in Figure 10, wherein said lower curtate extend into outer wall 5 withIn the cavity volume forming between inwall 6, and cable can be transported in door 2 by described lower curtate.

Figure 11 and 12 shows with respect to the rectangular horizontal stroke of pivot axis that connects hinge components 10 thereon through door hingeCross section, wherein door is opened (Figure 11) and door is closed (Figure 12). Pivot axis 3 extends past the axis of axle journal 20.

Cutaway view shows the section protruding upward 19 of axle journal 20, cable bundles 45 and the screw 46 of cross section, utilizesDescribed screw, installation portion 11 is connected to the body (not shown) of household electrical appliance. For reason clearly not shown hinge componentsPossible involucrum. Restriction is opened body 30 and can as recess 35, be seen from top, wherein, and described in the second section 34 is fixed toIn recess 35.

As shown in figure 11, the first section 32 that body 30 is opened in restriction engages after load bearing arm 12, and limited at doorIn region in open mode between the second section 14 and the end section 15 of load bearing arm 12, stop. In this wide open modeIn, the sidewall 28 that receives space 8 is pivoted in the recess being formed by bending of load bearing arm 12. Each section 13 of load bearing arm 12,14 and 15 are bent to, and in the time opening, sidewall 28 does not collide load bearing arm 12, although sidewall defines along the maximum of dotted line PThe circular arc of 135 °. In order to realize especially large open angle, the first section 32 that body 30 is opened in restriction is also in the gap of sidewall 28In 52, be arranged to, it even has large open angle and engages after load bearing arm 12.

For the closed position of door as shown in figure 12, the curved section 14 of load bearing arm 12 extend in attaching parts 7In the appearance bag 39 forming in wall 38. Holding bag makes especially the first section 13 to be set to grow especially and make Second RegionThe bending of section 14 is sharp-pointed especially, and this has realized the king-sized open angle of door.

The elastic movement that body is opened in restriction illustrates in further detail now with reference to Figure 13 and 14.

Figure 13 shows the cutaway view of attaching parts 7, and wherein, restriction is opened body 30 and sat idly in described attaching parts 7. ?In this situation, center arm 33 is at area supported 36 upper supports at oblique angle, and the first section is at upwards oblique angle, kink 46 places. TheTwo sections 34 leave from center arm 33 oblique angles at kink 48 places, and are connected to attaching parts 7 and thereby are connected by screw 31To door.

In Figure 14 from sidepiece with the identical parts shown in the mode of height explanatory view, in the figure only with voidLine shows and limits section 32,34 and the center arm 33 of opening body 30. Solid line has represented that the restriction in sitting position opensBody 30. Dotted line has represented that at the door restriction in the state in its limited open position opens the shape of body 30. Then, power F1Be applied on the first section 32 by load bearing arm 12. Therefore the kinetic energy carried is designated as R1 and R2 two in Figure 13 and 14In resilient path, be absorbed.

Depend on that power F1 acts on the distance of the kink 46 on the first section 32, the first section 32 can be inclined to one side along direction R1Turn, thereby it is bending in the direction. Because the first section is relatively short (roughly 5 to 10 millimeters), so it will be only bendingOne relatively little amount. In addition, bending radius can also flexibly increase at kink 46 places. The first section 32 along direction R1Large deflection reaches about 0.3 millimeter to 1 millimeter. In order to produce the enough spaces for this deflection, upper curtate 32 and sidewall regionSection 51 separates a gap. This gap has about 0.5 to 2 millimeter, the width e of 1 ± 0.2 millimeter preferably approximately.

On the other hand, center arm 33 and if necessary also have the second section 34 along the direction that is designated as R2 to up-bow.In this case, center arm 33 is sat idly in the region of kink 46 on area supported 36, thereby power is at area supported 36Upper effect, is shown in arrow F2. In addition, tension force is also effect on the second section 34 if necessary, and it is transferred to circumocular recessedPortion. Because the relatively large length of center arm 33 (about 20 to 30 millimeters), so that described arm will bend will visibly be curved, and by exampleAs bent curved about 0.2 millimeter to 2 millimeters along direction R. In this case, arm and if necessary also have the second section 34Bending and absorb in doing so elasticity energy. In addition the bending radius at kink 48 places and thereby the angle of bend at 48 places,Can flexibly increase, as shown in Figure 14.

Elastic movement R1 and R2 illustrate large in Figure 14. The power occurring in the time that door arrives its stop part will be partial to positionIn area supported 36 (power F2) and the circumocular recess at the oblique angle of below. In this case, power is distributed into well enoughAvoid damaging attaching parts 7.

The present invention thereby a kind of flexible door stop part is provided, it goes out when mode receiving gate arrives its stop part flexiblyExisting power also thereby prevents overvoltage.
