The specific embodiment

As the embodiment according to home appliances of the present invention, Fig. 1 shows vertical refrigerator 1, and described refrigerator has skeleton 4 and door 2, and described door can be hinged on the skeleton 4 pivotally around axis 3.Extend through to the beholder's of Fig. 1 dorsad of axis 3 and skeleton 4 parallel sided door 2.

Door 2 comprises outer wall 5, and described outer wall curves inwardly at the sidepiece place, and is advantageously formed by sheet material, particularly metallic plate.The cavity that so is formed in the door separates by the inner space of inwall 6 (referring to Fig. 2) with refrigerator, and described inwall advantageously is made of plastics.The cavity that is formed between outer wall 5 and the inwall 6 is filled with heat-insulating foam.

The transverse edge place is by connector 7 interconnection on door for outer wall and inwall, and described connector is the cavity from the closing door of top simultaneously.Connector 7 is obviously elongated and rectangle, and its length is similar to corresponding with the width of door.The height of connector 7 and the degree of depth are approximate corresponding with the thickness of door, and are respectively several centimetres.

In the bottom, cavity is also by following connector (not shown) gauge.It can form with upper connector 7 identical or differently.Be provided with on every side in connector 7 and receive space 8.In order to receive space 8 from the top cover cap, cover cap bar (not shown among Fig. 1 and 2) is assemblied on the connector 7.Door makes it to be hinged on the skeleton at either side preferably with respect to the longitudinal axis symmetry.

Fig. 2 shows the refrigerator of door Fig. 1 when opening.Therefore, two reception spaces 8 all can at length be seen.In a side of pivot center 3, the support arm that is fixed to the hinge components 10 on the top 9 of the front baffle of door 2 of skeleton 4 extend in the reception space 8 that is arranged on the there.The demonstration and/or the executive component that are used for refrigerator preferably also are arranged on forward part 9 places.

It can also be seen that from Fig. 1 and 2 outer wall 5 is longer than inwall 6 on the direction of pivot center 3, make connector 7 towards viewable side by outer wall 5 wholly or in part cover cap live.Therefore, from the outside, door 2 comprises the uniform outside that is formed by outer wall 5, and described outside has corresponding aesthetic feeling.

Fig. 3 shows the perspective view of the hinge components 10 that can see from Fig. 2.Hinge components 10 is formed by flat upright steel plate bar, and comprise the mounting portion 11 of the skeleton 4 that is used for fixing family expenses utensil 1 and 11 support arms of giving prominence to 12 from the mounting portion, place, end at described support arm is provided with two

identical fulcrum post

16a, 16b, and described fulcrum post is outstanding up and down respectively.Can see two holes 17 in mounting portion 11, described two holes are provided for and receive the screw (not shown), and hinge components 10 is fixed on the skeleton 4 of home appliances 1 via described screw.

Pivot center 3 is along the longitudinal extension of two fulcrum post 16a and 16b.On the direction of pivot center 3, the height B of hinge components 10 in the zone of two

fulcrum post

16a and 16b is bigger slightly than the height of mounting portion 11.The height B of two

fulcrum post

16a and 16b advantageously is 20mm-40mm, is preferably 30-35mm especially.Support arm 12 11 narrowly always is reduced to the free end that it is extruded with two

fulcrum post

16a and 16b from the mounting portion.Therefore, guarantee the not outstanding top 9 that surpasses the front baffle of skeleton 4 of hinge components 10, described top only is approximately the 40-60mm height, so that reduce the occupied amount of space of refrigerator.If support arm 12 has constant height (as prior art), then

fulcrum post

16a and 16b also can be obviously higher thereupon.

Hinge components 10 is symmetrical with respect to the plane vertical with the pivot center that is limited by fulcrum post 16a, 16b.Therefore, hinge components 10 can be used for left hand backstop and right hand backstop.

Fig. 4 shows the section of the hinge components 10 of Fig. 3 in the mode with the view mirror image of Fig. 3.Hinge components 10 has constant thickness d on its length, this thickness is approximate 5mm.The preferred bending of support arm 12 below will make an explanation referring to Fig. 4.

The mounting portion 11 that is fixed to skeleton 4 roughly is straight along line L1.11 one-tenth about obtuse angles of 105 ° ± 5 °, the first 13 and the mounting portion of support arm 12.First 13 initially roughly extends along line L2 directly, carries out the transition to crooked second portion 14 then.Crooked second portion 14 and then carry out the transition to the straight end 15 of extending along line L3.Part 14 has big bending, makes the angle γ that first 13 and end 15 forms less than 80 °, is 40 ° ± 5 ° in the example that illustrates.γ is more little for angle, and door 2 obtainable opening angles are just big more.

Because the bending of second portion 14, its free end is provided with the end 15 of fulcrum post 16 with respect to mounting portion 11 tilt angle alpha.Tilt angle alpha is preferably greater than 20 ° greater than 10 °, particularly is preferably greater than 30 °, is approximate 32 ° in example.

Because therefore the described bending of support arm 12, has formed recess 18, when door was opened, the sidewall that receives space 8 was pivoted in the described recess along the dotted line P that does not contact with mounting portion 11 more accurately.

Fig. 5 shows another perspective view of hinge components 10, and described hinge components is attached to the upper right turning of front baffle of the skeleton 4 of home appliances at this moment.Therefore, screwed hole is arranged in the top 9 of front baffle, so that screw passes hole 17.Fig. 5 shows the right backstop situation of door, because support arm 12 is crooked to the right.

As can be seen from Figure 5, support arm 12 11 contracts towards its free end is narrow from the mounting portion, says more accurately, to contract with respect to the mode of the plane symmetry vertical with pivot center is narrow.The narrow maximum that contracts in the first 13 continues narrow contracting then in second portion 14, contract or even have a constant height and end 15 is only narrow a little.Near linear ground, inclined-plane in first and the second portion extends, and is promptly approximate along straight line extension and expansion in one plane, up to carrying out the transition to end 15 under the situation of support arm 12.From the mounting portion 11 towards the end 15 inclined-planes that reduce by exponential manner also can expect.

Fig. 6 shows can the diagram corresponding with Fig. 5, and wherein, bearing journal is assemblied on the lower support pin 16b for 20 this moments.Bearing journal 20 is shown among Fig. 7 along the cross section of line VII.Bearing journal 20 comprises the lower part with cylindrical outer surface, and described lower part is arranged for being supported in the supporting eye that is fixed to door.In a side, shelly part 19b extends upward, and serves as the cable passage, and serves as the shell of the end that is used for hinge components 10.

Can be as seen from Figure 7, the hole 22 of square cross section is arranged in the bearing journal 20, and does not have play ground reception fulcrum post 16b.Cable passage 21 with ellipse or other any cross sections is provided for cable is directed to the door 2 from skeleton 4, and extends abreast with pivot center, and abutting aperture 22 is provided with.Cable passage 21 and hole 22 are preferably continuous.Bearing journal 20 is made by the material with low coefficient of friction, for example polyformaldehyde (POM) as moulding part.

Fig. 8 is the perspective view in the reception space 8 from door 2 the upper right turning that skeleton 4 is watched.The top that comprises the cover cap bar of door 2 is removed, so that better observability to be provided.Inwall 6 can below see that magnetic seal spare 29 is arranged on the outer edge of described inwall 6.Connector 7 is connected the top of inwall 6.Outer wall 5 is arranged on behind, and forms outer wall side part 25 towards edgewise bend.Thereby, the sidewall sections 51 common sidewalls 28 that form the reception space 8 in the door 2 of outer wall side part 25 and connector 7.

Receive that space 8 also comprises diapire 37 and towards the wall 38 of the visible face of door, recess 39 is recessed in the described wall 38.In the zone of recess 39, wall 38 and outer wall 5 parallel and very approaching or adjacent sidewall 5 extensions.

Supporting eye 24 also is formed in the connector 7 by shaping bearing sleeve 23, and bearing journal 20 (not shown among Fig. 8) is received in the described bearing sleeve 23.

At last, can see opening limited part 30 in Fig. 8, described opening limited part 30 is formed by wire piece, and described wire piece comprises and the approximate first 32 of extending abreast of pivot center.This first 32 engages with support arm 12 from behind, therefore limits the open limit position of door.At the other end of opening limited part 30, second portion 34 is bent forming eye, and is received in the groove 35 in the bottom 37 of connector 7.Therefore, it utilizes effectively to cooperate and is fixed to door.Second portion 34 is also by being fixed in the heart in the screw 31 insertion eyes.The centre portion 33 of opening limited part 30 extends along stayed surface 36, and described stayed surface 36 is with respect to pivot center 3 skewed crossing orientations, and also is formed in the bottom 37 of connector 7.

Similar with Fig. 6, Fig. 9 shows the perspective view at the upper right turning of refrigerator 1, and wherein, door is hinged.Compare with Fig. 6, the lower part of bearing journal 20 is received in the bearing sleeve 23 of supporting eye 24 pivotally.In this case, the first 32 of opening limited part 30 engages with support arm 12 from behind, therefore is blocked in Fig. 9.Receiving space 8 quilt cover cover fillets 43 lives from the top cover cap.

Fig. 9 also shows cable bundle 45, and described cable bundle is directed in the cavity of door in 2 by the cable passage 21 in the bearing journal 20.

Figure 10 also shows the perspective view at the upper right turning of refrigerator, and wherein, door is hinged, but does not have cable bundle 45 and cover cap bar 43 is removed.The shell of hinge components also is shown among Figure 10, and is formed by plastic components 40,41 and 42.

In Figure 10, the lower part of bearing sleeve 23 also can see, and is projected in the cavity that is formed between outer wall 5 and the inwall 6, thereby, cable can be directed in the door 2 by described lower part.

Figure 11 and 12 shows the cross section that vertically passes through hinge components 10 when door when opening (Figure 11) and closing (Figure 12) with pivot center, wherein is hinged on the described hinge components.In each case, pivot center 3 all extends through the axis of bearing journal 20.

In described cutaway view, can see the part that projects upwards 19 of bearing journal 20, cable bundle 45 and the screw 26 that cuts off, mounting portion 11 is fixed on the skeleton (not shown) of home appliances via described screw.For the sake of clarity, the possible shell of not shown hinge components.Opening limited part 30 can see from the top, and also can see groove 35 from the top, and the second portion 34 of described opening limited part is fixed in the described groove.Connector 7 is lived by outer wall 5 cover caps towards viewable side, and described outer wall curves inwardly at the place, side end face of door and forms outer wall side part 25.The antetheca 38 of connector 7 also curves inwardly at the place, side end face of door and forms part 55, and extends abreast with outer wall 5 part behind at outer wall 5.

What also can see from Figure 11 is that when door was in open limit position, the first 32 of opening limited part 30 engaged with support arm 12 from behind, and stopped at there in the second portion 14 and the zone between the end 15 of support arm 12.At this wide open position, the sidewall 28 that receives space 8 is pivoted in the recess that is formed by bend in the support arm 12.The

part

13,14 and 15 of support arm 12 is bent to and makes sidewall 28 open Shi Buhui at door to run into support arm 12, although sidewall 28 has been described curve up to 135 ° along dotted line P.In order to allow to have king-sized opening angle, the first 32 of opening limited part 30 also is arranged in the breach 52 in the sidewall 28 like this, makes that it also engages with support arm 12 from behind under the situation of big opening angle.

Breach 52 forms (referring to Figure 12) by the protuberantia in the wall of connector 7.Especially, the part 55 of antetheca 38 is in the outwards bending of the zone of breach 52, with the sidewall sections 51 that forms outside skew.At this some place, outer wall side part 25 is recessed, makes the sidewall sections 51 of connector 7 form the outside visible wall of door.Therefore, have a uniform visible face in order to make door, sidewall sections 51 extend abreast with outer wall side part 25 and a little with its lapping, but concordant with outer wall side part 25 basically.

In the closed position of door shown in Figure 12, the sweep 14 of support arm 12 extend in the recess 39, and the female portion is formed in the wall 38 of connector 7.Because recess 39, therefore, first 13 can be configured to long especially and the structure for curvature section of second portion 14 can be become big especially, this can realize the king-sized opening angle of door.

Below, explain the elastic movement of opening limited part in more detail referring to Figure 13 and 14.

Figure 13 shows the cross section by connector 7, and opening limited part 30 is put and is located on the described connector.Section 33 is supported on the oblique stayed surface 36, and first's upwards bending at bending part 46 places.Second portion 34 bends away from section 33 at bending part 48 places, and is fixed to connector 7, thereby is fixed on the door by screw 31.

In Figure 14, identical parts have also been reproduced by highly schematic mode, the only outer line that is illustrated as of the

part

32,33 of opening limited part 30 and section 34 with side view.Continuous line represents to be in the opening limited part 30 of rest position.Dotted line is represented the shape of opening limited part 30 when door stops at the state of its open limit position.Power F ₁Be applied in the first 32 by support arm 12.So the kinetic energy that transmits is received in two resilient path, described resilient path in Figure 13 and 14 with R ₁And R ₂Indicate.

According to the power F that acts on first 32 ₁From the distance of bending part 46, first 32 can be along direction R ₁Buffering is provided, and whereby, it is crooked in the direction.Because first 32 relatively short (approximate 5-10mm), therefore, it is only crooked relatively slightly.And the radius of curvature at bending part 46 places also may flexibly increase.First 32 is along direction R ₁Maximum deflection be approximate 0.3-1mm.For for this direction provides enough spaces, top 32 and sidewall sections 51 spaced apart a certain gaps.The gap has approximate 0.5-2mm, the preferred width e of approximate 1 ± 0.2mm.

On the other hand, section 33 (and also possible second portion 34) edge is with R ₂The direction of expression is bent upwards.Section 33 is supported on stayed surface 36 places in the zone of bending part 46, make masterpiece be used for stayed surface 36 (referring to arrow F ₂).And tension force also can act on the second portion 34, and described second portion 34 is introduced on the groove around eye.Because the relatively long length (approximate 20-30mm) of section 33, so it can be at direction R ₂Last appearance is obviously crooked, more particularly, and for example crooked approximate 0.2-2mm.Section and possible second portion 34 bendings, thus potential energy absorbed.Also can flexibly increase in the radius of curvature at bending part 48 places and then the angle of bend at Reference numeral 48 places, this can be as seen from Figure 14.

Below, at length explain the structure of eye again referring to Figure 15 and 16.Figure 15 is the diagram identical with Fig. 8, that is, be the perspective view that receives space 8, and described reception space has part and dissects side and antetheca.Figure 16 shows suitable diagram from similar angle, but does not have the part of dissecing.Therefore, the top of connector 7 also can see, and is closed flange 59 (top cover) and seals from the top.On this assembly after upper cover bar 43 is assemblied in.

Please referring again to Figure 15, the first 32 of opening limited part 30 extends in the breach 52.As described in conjunction with Figure 13, the sidewall sections 51 spaced apart a certain gaps of first 32 and connector 7 are so that provide elastic buffer on this direction.

Towards the front (visible face) of door, connector is by outer wall 5 cover caps, and described outer wall is formed by door face board in this example.At sidepiece, this panel curves inwardly and forms outer wall side part 25.Connector 7 also comprises antetheca 38, and described antetheca curves inwardly at sidepiece and forms part 55.In the edge of outer wall side part 25, part 55 is towards 56 bendings of short wall part, and described wall part 56 is from front gauge breach 52.On the one hand, sidewall sections 51 is connected to wall part 56, extends and form the second restriction portion of breach 52 along the direction of skeleton.Breach 52 opens wide in both sides.Can be as seen from Figure 16, it has rectangular cross section, and extends to closure flange 59 on the total height of connector.

The part 58 of groove that is formed for receiving the edge of outer wall side part 25 with wall part 55 is jointly also extended towards the front from wall part 56.

Figure 17 and 18 shows the perspective view of connector 7, and wherein, connector 7 decomposes with outer wall 5, and Figure 17 shows the view of watching from the top from the right side, and Figure 18 shows the view of watching from the below from the right side.

Except above-mentioned architectural feature, the shape that forms the outer wall 5 of outer wall side part 25 in lateral curvature can be seen in Figure 17 and 18 particularly well.Yet the last turning of outer wall side part is recessed at Reference numeral 62 places.In zone 62, the outside visible wall of door is formed by the outside of the sidewall sections 51 of connector 7.

In Figure 17, also can see the downside of connector 7.This comprises wall part 73 and two

walls

74,75 that are used to provide stability towards skeleton.Inwall 6 (not shown) of door are attached to towards the below of the wall part 73 of skeleton.The diapire 37 that receives space 8 is by these

wall

74,75 cover caps.Bearing sleeve 23 extends downwardly into the cavity from supporting eye 24, thereby cable can be directed into the door from skeleton.Rib 71 is outstanding downwards between the sidewall sections 51 in sleeve 23 and reception space 8, and snapclose sheet 70 is formed on the described rib.At assembled state, snapclose sheet via its kayser face 80 from behind with the edge join of the first crimp part 77 of outer wall 5, the described first crimp part 77 is blocked in Figure 17, but can see in Figure 18.

According to Figure 18, outer wall 5 forms outer wall side part 25 at the left lateral bending of door, described outer wall side part 25 forms by outer wall 5 visible face or the front near normal give prominence to.Inwardly curving end, outer wall side part 25 is bent to form the first crimp part 77 again.The first crimp part 77 is extended abreast in that its edge and outer wall side part 25 are approximate, makes the visible face of its edge 82 towards door.

When connector 7 was assemblied on the sidewall 5, kayser hook 70, connected thereby form reliably after the kayser edge 82 of the first crimp part 77 via its kayser face 80 kaysers.

The sidewall sections 51 that receives space 8 moves in the zone 62, and in described zone, otch forms outside in the wall 5.Sidewall sections 51 a little with outer wall side part 25 lappings, to produce concordant as far as possible continuous outside.

Up, door face board curves inwardly a little and forms crimp 63.When connection 7 was assembled, crimp 63 moved in the groove that is formed in the closure flange 59.
