One opposite house 12 links to each other with main body 10 by hinge.Door 12, is used for opening and closing cold room around the hinge rotation with respect to main body 10.Door 13 is arranged on the bottom of main body 10, is used to open and be closed in the refrigerating chamber 11 of main body 10 bottoms.Door 13 reaches forward backward with respect to main body 10 and moves, and door 12 rotates around hinge.Therefore, do not need hinge or pivot that door 13 is connected to main body 10.

A plurality of tracks 40 are arranged between main body 10 and the door 13, are used for the slip of steering gate 13 smoothly, as illustrated in fig. 1 and 2.Track 40 is arranged in the both sides of door 13, and comprises first track 41 that is fixed in main body 10 and second track 42 that is fixed to door 13 rear portions.Perhaps, as shown in figure 12, can be provided with support 25, the second tracks 42 that fixedly secure with door 13 rear portions and can be fixed to support 25.

By sliding, first track 41 can move with respect to second track 42, and vice versa.For first and

second tracks

41 and 42 are slided smoothly, a plurality of balls or roller can be arranged between first and second tracks 41 and 42.First track 41 can be arranged on second track 42, and vice versa.Perhaps, as shown in Figure 5, track 41 can insert in second track 42, and vice versa.And track 40 can comprise three or more than three track connected to one another.

As illustrated in fig. 1 and 2, at least one container that is used for hoarding food therein 20 is arranged on refrigerating chamber 11 in refrigerating chamber 11 bottoms, and as shown in Figure 1, and at least one drawer 15 is arranged on the container 20 in the refrigerating chamber 11.Container 20 moves along with the motion of door 13 reaches forward backward with respect to main body 10, and drawer 15 can be independent of the motion of door 13 and move.For user's convenience, when door 13 complete openings, container 20 can automatically rise.In one embodiment, shown in Fig. 2 and 3, refrigerator is provided with lifting device 30.Lifting device is fixed to door 13 rear surface, and container 20 is placed on the lifting device 30 and by lifting device 30 and supports.

Fig. 3 at length shows the structure of lifting device 30.The detailed structure of lifting device 30 is described below with reference to Fig. 3.With reference to figure 3, lifting device 30 comprises the lifter 31 of laying container 20 on it, a pair of lifting track 32 of door 13 and the driver element that is used for automatically promoting lifter 31 of being fixed in, and wherein promotes the lifter motion that track 32 is used to guide lifter 31.

For example, lifter 31 has " L " shape bending.The vertical portion of lifter 31 links to each other with a pair of lifting track 32 that is fixed to door 13 back sides vertically, and the horizontal part of lifter 31 is supporting the container of laying thereon 20.When door 13 is opened, lifter 31 by driver element along promoting track 32 upwards and move down.

Driver element comprises that at least one links to each other to come the driving shaft 36 of turning arm 37 with respect to door 13 rotatable arms 37, motor 34, the gear assembly 35 that links to each other with the axle of motor 34 and with gear assembly 35 and cantilever 37.In the illustrated embodiment, two arms 37 are arranged in basifacial both sides, door 13 backs.Motor 34 is fixed to door 13 back sides, and is arranged between two arms 37.Motor 34 is controlled by the controller (not shown) of refrigerator, or controls by being independent of the submaster controller (not shown) that controller is used for operating electrical machines 34.

The bottom surface of lifter 31 is supported in the end that roller 37a is arranged on arm 37.When arm 37 rotated by motor 34, roller 37a reached forward on the bottom surface of lifter 31 backward and rolls.As shown in Figure 3, inclined-plane projection 31a is set on the bottom of lifter 31, and when lifter 31 was promoted fully, roller 37a rolled and crosses projection 31a.Therefore, because roller 37a supports by projection 31a,, can prevent that also the lifter 31 that promotes fully from falling downwards even therefore when motor 34 stops.

Have upper sensor 38a at lifting track 32 tops, have lower sensor 38b in lifting track 32 bottoms.Upper sensor 38a and lower sensor 38b detect lifter 31 respectively and are in top or the bottom that promotes track 32, and signal is issued controller.After receiving signal, controller stops motor 34.Therefore, lifter 31 range of movement are limited, and this can prevent that lifter 31 breaks away from from promoting track 32.Perhaps, can upper limit switch (not shown) be set at lifting track 32 tops and the limit switch (not shown) be set in lifting track 32 bottoms.The power supply that upper limit switch and limit switch are sent into motor 34 by cut-out can directly stop motor 34.

In one embodiment, lifter 31 just automatically promotes or is promoting automatically after through one period scheduled time behind door 13 complete openings at door 13 1 complete openings, thereby and the lifter 31 that promotes fully automatically move down when closing once promotion slightly when door.Perhaps, can control lifting device 30 by pressing control button, the control button (not shown) can be set on

door

12 or 13 in order to make the user.

When control button is pressed or behind door 13 complete openings during through the scheduled time, motor 34 is started working.Then, gear assembly 35 turns round so that rotating driveshaft 36 by motor 34.When driving shaft 36 rotation, arm 37 begins rotation, and the roller 37a of arm 37 ends begins to rise, and rolls on the bottom of lifter 31 simultaneously.Therefore the lifter 31 same containers 20 that are placed in together on the lifter 31 begin to rise together.When lifter 31 promoted fully, upper sensor 38a detected lifter 31 and signal is issued controller.Behind the reception channel signal, controller stops the lifter motion that motor 34 stops lifter 31.At this moment, in the side interlock of the roller 37a of arm 37 ends and inclined-plane projection 31a and by its support.Therefore, can effectively prevent arm 37 counter motion and since gravity lifter 31 along with container 20 moves downward.

Simultaneously, after food being taken out by container 20 or new food put into container 20, the user presses control button or slightly promotes 13 towards the main body 10 of refrigerator.Then, its axle of motor 34 reverse rotations, so lifter 31 and container 20 move down together.In the situation that lifter 31 and container 20 are fallen fully, lower sensor 38b and controller stop to move downward of lifter 31.Then, the user can put into refrigerating chamber 11 with container 20 by promoting door 13 towards main body 10.

As mentioned above, along with door 13 should be powered by the power supply in the refrigerator main body 10 16 (as shown in Figure 2) with respect to the lifting device 30 that refrigerator main body 10 moves.Perhaps, possible other electric component such as display floater or touch pad etc. that is arranged on the door 13 needs electric power.And also possible is can be arranged on the door 13 such as other electric components that sends signal of need communicating by letter with controller such as sensors.Like this, just need make by the lead of for example cable or holding wire with respect to main body 10 movably electric component link to each other with controller with at least one power supply 16 in the main body 10.

One embodiment of the present of invention are provided with respect to main body 10 lead 100 that is electrically connected of the power supply 16 in electric component and the main body 10 or controller movably.Lead 100 comprises the wiring of at least one power cable, signal cable and other type.In order to prevent that lead 100 is loose and by other parts damages of refrigerator, when electric component moves or during with door 13 moving on first direction along first direction, lead 100 is extending and shrink on first direction.In the illustrated embodiment, first direction is a horizontal direction.Yet the present invention also can be applicable to can be at the lead of vertical direction or elongation of other direction and contraction.The various embodiment and the distortion thereof of lead 100 are shown in Fig. 2 and 4A to 15B.Will be with reference to all embodiment and the distortion thereof of describing lead 100 corresponding to the accompanying drawing of each embodiment and distortion thereof in detail.

In Fig. 2 and 4A to 5, at length show first embodiment of lead 100.Shown in above-mentioned figure, comprise first section joint 110 and with respect to first section joint 110, second section joint 120 movably according to the lead 100 of first embodiment.According to the motion of electric component, 110 and second sections joints 120 of first section joint can be electrically connected and disconnect mutually.First section the joint 110 and second sections the joint 120 both comprise electrode cable and negative pole cable respectively.

First section joint 110 have first end that links to each other with power supply 16 in main body 10 and with the first end second opposed end.Second section joint 120 have first end that links to each other with electric component such as lifting device 30 and with the first end second opposed end.Second end of second end of first section joint 110 and second section joint 120 is connected to each other when door 13 is opened, and disconnects each other when door is closed.Thus, shown in Fig. 4 A to 4C, in the illustrated embodiment, first terminals 111 are arranged on second end of first section joint 110, and second terminals 121 are arranged on second end of second section joint 120.

In one embodiment, first section joint 110 is fixed in main body 10 and can not moves with respect to main body 10, and second section joint 120 is fixed to electric component or door 13 such as lifting device 30.Although first section joint 110 can not move with respect to main body 10, second section joint 120 can reach forward backward with respect to main body 10 along with the motion of the motion of electric component or door 13 and move.Second section joint 120 can be fixed to door 13 or fixedly secure rigid support on door 13.

When door 13 is closed refrigerating chamber 11,110 and second sections joints of first section joint, the 120 next longitudinal lengths that shorten lead 100 stacked on top of each other.At this moment, shown in Fig. 4 C, first terminals 111 and second terminals 121 disconnect each other.Therefore, when door 13 was closed, the electric power of power supply 16 can not be sent into the electric component such as lifting device 30 grades in the main body 10.

On the other hand, when door 13 moves forward when opening refrigerating chamber 11 with respect to main body 10, first and

second terminals

111 and 121 are close to each other, and the longitudinal length of lead 100 is elongated simultaneously.At last, shown in Fig. 4 B, first and

second terminals

111 and 121 are electrically connected to each other, and when door 13 complete openings, the length maximum of lead 100.Therefore, when door 13 is opened, the electric power of power supply 16 in main body 10 can be sent into electric component such as lifting device 30 grades.

Perhaps, as shown in Figure 5,110 and second sections joints 120 of first section joint are fixed to first track 41 and second track 42 respectively.Because second track 42 moves with respect to first track 41 along with the motion of door 13, therefore second section joint 120 moves with respect to first section joint 110 along with the motion of door 13 equally.

First track 41 can be cylindricality, hollow square cylindricality for example shown in Figure 5.In order to protect 110, the first sections joints 110 of first section joint can be arranged in the inside of first track 41 by first track 41.For not because gravity and slacken, first section joint 110 can be firmly-fixed to the inner surface of first track 41.As shown in Figure 5, when first section joint 110 was arranged in first track 41, first terminals 111 in first track, 41 ends were arranged on the outer surface of first track 41.Because first terminals 111 are exposed to the outside of first track 41, therefore first terminals 111 can contact with second section joint 120.

First track 41 can insert second track 42 along the longitudinal direction of second track 42, and in order to prevent that second section joint 120 from being damaged by first track 41, second section joint 120 is arranged in the outside of second track 42.For not lax, second section joint 120 can be securely fixed on the outer surface of second track 42.When second section joint 120 was arranged on the outer surface of second track 42, second terminals 121 were arranged on the inner surface of second track 42 towards first track 41.Therefore, can contact with first terminals 111 on first track, 41 outer surfaces at second terminals 121 on second track, 42 inner surfaces.

As mentioned above, second section of lead 100 joint 120 is arranged in the outside of second track 42, and first section joint 110 is arranged in the inside of first track 41.In order to protect the second section joint 120 that exposes, an over cap 50 is set as shown in Figure 5.Over cap 50 is fixed to the outer surface of second track, and second section joint 120 is arranged between second track 42 and the over cap 50.

Perhaps, second track 42 can be square post, and second section inside that joint 120 can be arranged in second track 41.In this case, first track 41 can insert second track 42, and first section outside that joint 110 can be arranged in first track 41.And over cap 50 can be fixed to first track 41.As mentioned above, in order to protect a part of lead 100 that exposes to the

track

41 and 42 outsides, over cap 50 can be fixed to any one in first track 41 and second track 42.

In operation, when door 13 was closed shown in Fig. 4 C, first and

second tracks

41 and 42 were stacked on top of each other.At this moment, first and

second terminals

111 and 121 that are fixed to first track 41 and second track 42 respectively disconnect each other, so the electric power of power supply 16 can not be supplied to for example electric component of lifting device 30 in the main body 10.

On the contrary, when door 13 is opened, first and

second tracks

41 and 42 elongations.Therefore, first and

second terminals

111 and 121 that are fixed to first track 41 and second track 42 respectively are connected to each other.Therefore, the electric power of power supply 16 can not be supplied to for example electric component of lifting device 30 in the main body 10.

Therefore, in first embodiment,

track

41 and 42 not only played guiding container 20 track effect but also play the effect of lead guiding piece.

Figure 6 illustrates distortion according to the refrigerator of first embodiment of the invention.As shown in Figure 6, in distortion, be provided with the lead guiding piece 60 that is independent of

track

41 and 42 according to the refrigerator of first embodiment.According to the motion of the electric component of for example lifting device 30 or door 13, lead guiding piece 60 is extending and shrink along its longitudinal direction.

Lead guiding piece 60 comprises first guiding piece 61 that is fixed to refrigerator main body 10 and directly is fixed to door 13 or is firmly-fixed to second guiding piece 62 on the supporter of door on 13.When inserting second guiding piece 62 or opposite by the longitudinal direction along second guiding piece 62, and when door 13 closed, first guiding piece 61 and second guiding piece 62 were stacked.Therefore, according to the motion of electric component or door 13, by the relative motion of first and

second guiding pieces

61 and 62, lead guiding piece 60 can and shrink along its longitudinal direction elongation.Therefore these mechanisms and first and

second tracks

41 and 42 very similar will omit the more detailed description about lead guiding piece 60 structures.

As shown in Figure 6, in the distortion of first embodiment of the invention, lead 100 also comprises the first section joint 110 that is fixed to first guiding piece 61 and is fixed to second section joint 120 of second guiding piece 62.According to the motion of for example electric component of lifting device 30 or the motion of door 13, first and second sections joints 110 and 120 are electrically connected or disconnection.In one embodiment, first and second sections joints 110 and 120 have terminals in its end respectively.

In addition, first section joint 110 can be arranged in first guiding piece, 61 inside, and second section joint 120 can be arranged in the outside of second guiding piece 62, and be perhaps opposite.For the exposed portions serve of guardwire 100, over cap (Fig. 6 is not shown) can be fixed on first and second sections at least one that save in 110 and 120.Parts shown in these mechanisms and the above-mentioned Fig. 4 A to 8 are very similar, therefore will omit the more detailed description about lead guiding piece 60 and lead 100 structures.

In the distortion of first embodiment of the invention, door 13 reaches forward backward so that opening and close the motion of refrigerating chamber 11 guide smoothly by first and

second tracks

41 and 42 with respect to main body 10, and first and second sections saved 110 and 120 stable relative motions and guided by first and second guiding pieces 61 and 62.Certainly, when door 13 was opened, first and second sections joints 110 and 120 were connected to each other, and when door 13 was closed, they disconnected.Simultaneously, cable guide 60 can comprise three or more than three guiding piece connected to one another.

Fig. 7 to 9 shows second embodiment of lead 100, and this embodiment will be described in detail belows.Comprise by its elasticity, and the flexible coil portion 130 of shrinking extending according to the lead 100 of second embodiment along its longitudinal direction.

When lead 100 was subjected to tension force, in order to add the aggregate level length of long lead 100, coil portion 130 can be along its longitudinal direction elongation.On the other hand, when removing tension force, in order to shorten the aggregate level length of lead 100, the coil portion 130 of elongation can shrink along its longitudinal direction.First end of lead 100 is fixed to power supply 16 or the controller in main body 100, and second end of lead 100 is fixed to for example electric component of lifting device 30.When door 13 was opened, lead 100 was subjected to pulling force, so the total length of lead 100 is owing to coil portion 130 elongations maximize.On the other hand, when door 13 was closed, the pulling force that lead 100 is subjected to was cancelled, so the total length of lead 100 minimizes by its elastic shrinkage owing to coil portion 130.

Coil portion 130 can form on the total length of the maximum of lead 100.Yet in this case, when shrinking, lead 100 may be owing to gravity relaxes.Therefore, lead 100 is owing to gravity relaxes in order to prevent to shrink, and coil portion 130 can become the part of lead 100.In addition, can be provided with that auxiliary conductor guiding piece 70 prevents that lead 100 from relaxing owing to gravity and owing to other parts of refrigerator damage.Auxiliary conductor guiding piece 70 can be in a tubular form, and as shown in Figure 8, lead 100, especially coil portion 130 can be arranged in the auxiliary conductor guiding piece 70 or pass auxiliary conductor guiding piece 70 and arrange.

Auxiliary conductor guiding piece 70 is arranged along door 13 travel directions.As shown in Figure 9, the minimum length of auxiliary conductor guiding piece 70 is set for and is satisfied such condition, that is, for the coil portion that prevents to shrink 130 owing to gravity relaxes, auxiliary conductor guiding piece 70 can hold the coil portion 130 that shrinks fully therein fully.And the maximum length of auxiliary conductor guiding piece 70 can be set for and satisfy such condition,, as shown in Figure 9, when door 13 is closed fully, can prevent that auxiliary conductor guiding piece 70 from bumping against main body 10 that is.

Auxiliary conductor guiding piece 70 is arranged in
