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 37 simultaneously.Therefore lifter 31 also the container on being placed in lifter 31 20 begin to raise.When lifter 31 was promoted fully, upper level sensor 38a detected lifter 31 and signal is issued controller.Behind the reception channel signal, controller stops motor 34 to stop the lifter motion of 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 the counter motion of arm 37 and move downward with container 20 by the lifter 31 that gravity causes.

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.Under the situation that lifter 31 and container 20 are fallen fully, following level 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, with respect to refrigerator main body 10 with door 13 movably lifting device 30 power by the power supply in the refrigerator main body 10 16 (as shown in Figure 2).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 that other electric components such as sensor that send signal such as communicating by letter with controller can be arranged on the door 13.In this case, just need make by lead such as feed cable or signal cable with respect to main body 10 movably the power supply 16 in electric component and the main body 10 link to each other with in the controller at least one.

One embodiment of the present of invention provide a kind of will be 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.This lead 100 comprises at least a in electrical lead and the signal conductor.Because electric component is movable, and power supply 16 or controller can not move with respect to main body 10, therefore lead 100 lax or tensions when electric component moves with respect to refrigerator main body 10.Therefore, lead 100 may be tangled by the miscellaneous part of refrigerator or damage when electric component moves together with door 13.

Therefore, the invention provides a kind of structure, be used to hold the slack of the lead that when first direction moves, is produced when electric part, prevent that lead is tangled or damages when electric component moves with respect to main body 10.The embodiment of this structure is shown in the of the present invention various embodiment of Fig. 2, Fig. 4 to Figure 11.Below with reference to the every kind of embodiment that describes this structure corresponding to the accompanying drawing of each embodiment length by length.In addition, in an illustrated embodiment, this first direction is a horizontal direction.But should be noted that the present invention can be used for any direction of electric component or door motion.

To shown in Figure 7, comprise the jack-post 200 that lead 100 can hang thereon as Fig. 2, Fig. 4 according to the structure of first embodiment of the invention.This jack-post 200 is substantially disposed in the middle part of this lead 100 and supports this middle part.Because jack-post 200 supports the middle part of this lead 100, therefore this lead 100 is not lax too many when door 13 is closed.In addition, below this jack-post 200, enough spaces are arranged, be not wound so that the slack of lead 100 is formed on below this jack-post 200.Specifically, direction is crooked below jack-post 200 longitudinally along being parallel to this lead 100 for lead 100 when door 13 is closed, as shown in Figure 6.

In order to make lead 100 crooked and do not twine, preferably but not necessarily, this lead 100 comprises sweep in the middle, as Fig. 2 and shown in Figure 4.The sweep of lead 100 can have serpentine, and specifically, the upper suspension of lead 100 sweeps is on this jack-post 200 and by its support.The top of this sweep can be permanently crooked, so that when electric component moves with respect to refrigerator main body 10 with door 13, be suspended on reliably on this jack-post 200.For fear of entanglement, the bottom of this lead 100 is along the direction bending that is parallel to these lead 100 tops.

Lead 100 also can expose.But protect this lead 100 for greater safety, preferably but not necessarily, this lead 100 is surrounded by the miscellaneous part of refrigerator.Embodiments of the invention provide a kind of structure, and this lead 100 is arranged to pass the track 40 of guiding door 13 motions, as Fig. 2 and shown in Figure 4.Therefore, lead 100 is besieged and protected reliably.

More particularly, this first track 41 and second track 42 have Hollow Pillar shape respectively.And first track 41 is in vertical insertion second track 42 of second track 42, and as shown in Figure 4, and vice versa.In addition, this lead 100 is arranged to pass simultaneously this first and

second track

41 and 42.

In this case, jack-post 200 is arranged in this first track 41 and is fixed in this first track 41, as shown in Figure 4.In addition, between the bottom of this jack-post 200 and this first track 41, guarantee certain space.This space is enough spacious, so that the slack of lead 100 is crooked and when door 13 moves, can not be tangled, and do not interfere with the motion of

track

41 and 42 in this

track

41 and 42.

Alternatively, refrigerator according to first embodiment also can be provided with the lead guiding piece 50 different with

track

41 and 42, this lead 100 is arranged to pass this lead guiding piece 50, and jack-post 200 is arranged in this lead guiding piece 50 and is fixed in this lead guiding piece 50, as shown in Figure 7.According to electric component is the motion of lifting device 30 or door 13, and this lead guiding piece 50 vertically is extensible and withdrawal along it.

Specifically, this lead guiding piece 50 comprises first guiding piece 51 that is fixed in this refrigerator main body 10 and is directly fixed on door 13 or is fixed in second guiding piece 52 that is securely fixed in the support member on the door 13.Because this first guiding piece 51 vertically is inserted in this second guiding piece 52 along this second guiding piece 52, when door 13 was closed, first guiding piece 51 can be overlapping with this second guider 52, and vice versa.

Therefore, by this first and second guiding piece 51 that causes according to this electric device or door 13 motion and 52 relative motion, this lead guiding piece 50 vertically can extend and can withdraw along it.Very similar first and second tracks 41 of these mechanisms and 42 structure, and lead 100 layouts that are arranged in this lead guiding piece 50 are very similar to top layout with reference to figure 2 and Fig. 4 to Fig. 6 description, therefore, will be removed about detailed description embodiment illustrated in fig. 7.

In the embodiment shown in fig. 7, in order to open and close refrigerating chamber 11, door 13 with respect to main body 10 forward and motion backward guide smoothly by first and

second tracks

41 and 42, and lead 100 is protected firmly by first and second guiding pieces 51 and 52.Simultaneously, though do not illustrate in the accompanying drawing, lead guiding piece 50 can comprise interconnective guiding piece more than three or three.

Be in operation, as Fig. 2 and shown in Figure 5, when door 13 is opened fully, except lead 100 the sweep at basic middle part always along its longitudinal tensile strain, and be suspended on this jack-post 200.The bottom surfaces of this curved portions is to the main body 10 of refrigerator.

When electric component during along horizontal motion, the bottom of this sweep can be along horizontal motion.For example, in an illustrated embodiment, when electric component or door 13 during towards main body 10 motion, move towards this chamber along horizontal direction in the bottom of this sweep, as shown in Figure 6.On the other hand, when electric component or door 13 leave this main body 10 and when moving, move towards leaving this chamber along horizontal direction in the bottom of this sweep along horizontal direction, as shown in Figure 5.Lead 100 along continuous straight runs on this jack-post 200 have fixing length.When electric component along continuous straight runs during towards the motion of this chamber, the length of these lead 100 slacks of along continuous straight runs increases under this jack-post 200, and minimizing when the electric component along continuous straight runs leaves the motion of this chamber.Therefore, prevent that when door 13 moves with respect to main body 10 this cable 100 from tangling, and do not interfere with the motion of door 13.

Comprise the lead casket 310 of lead 100 slacks that reception is caused by gravity according to the structure of second embodiment of the invention, as shown in Figs. 8 to 11.This lead casket 310 is contained in the slack of lead 100 wherein and covers this slack, so the miscellaneous part of refrigerator and/or user's hand can not contact with the slack of lead 100.Therefore this slack is protected reliably.The detailed structure of lead casket 310 is described below with reference to above-mentioned accompanying drawing.

This lead casket 310 is arranged between the side and main body 10 of container 20, for example, and the sidewall of refrigerating chamber 11 as shown in Figure 9.As shown in Figure 9, the slack that this lead casket 310 comprises lead 100 by its insertion the top of opening wide 311 and be fixed on the casket lid 313 of these refrigerating chamber 11 sidewalls, in this casket lid, form the space that holds lead 100 slacks.

But preferably optionally; this lead casket 310 be arranged on this lead 100 below; this lead is connected in power supply 16 or controller on the main body 10 with the electric component on the door 13; then, since the slack of the lead 100 that causes of gravity inserts in this lead casket 310 naturally by the top of opening wide 311 and by casket this 313 protect.

Structure according to second embodiment of the invention can also comprise auxiliary conductor guiding piece 320, and its slack with lead 100 is directed in the lead casket 310, as shown in Figure 8.This auxiliary conductor guiding piece 320 will prevent that the slack of lead 100 from coming out from this lead casket 310.Auxiliary conductor guiding piece 320 comprises first end and second end.The detailed structure of auxiliary conductor guiding piece 320 will be described below.

First end of this auxiliary conductor guiding piece 320 can be directly fixed on the door 13.For example, this first end can be arranged on this sidepiece of 13.Alternatively, first end of this auxiliary conductor guiding piece 320 can be connected in and be fixed on this element of 13, for example, and on track 40 support 25 fixed thereon.Alternatively, first end of this auxiliary conductor guiding piece 320 can be connected in this track 40, more particularly, is connected in second track 42.Second end of this auxiliary conductor guiding piece 320 extends towards the inner space of this lead casket 310 from this first end.

Lead 100 is arranged to pass this auxiliary conductor guiding piece 320.In one embodiment, passage 325 is arranged on the auxiliary conductor guiding piece 320 to second end from first end of auxiliary conductor guiding piece 320.More particularly, lead 100 enters this auxiliary conductor guiding piece 320 by first end, comes out from this auxiliary conductor guiding piece 320 by second end after passing this passage 325, as shown in Figure 8.A part of passing the lead 100 of this auxiliary conductor guiding piece 320 can be fixed in this auxiliary conductor guiding piece 320.Because second end face of this auxiliary conductor guiding piece 320 to the inner space of this lead casket 310, therefore brings out a part of lead 100 that comes from second of this auxiliary conductor guiding piece 320 and enters lead casket 310.

But regardless of the position of electric component and door 13, second end of this auxiliary conductor guiding piece 320 always inserts in this lead casket 310 by the top of opening wide preferably optionally.More particularly, when door 13 was opened fully, second end of this auxiliary conductor guiding piece 320 was arranged in the lead casket 310, as shown in figure 10.Then, the slack of lead 100 always is directed in this lead casket 310.Therefore, when electric component and door 13 motions, lead casket 310 can prevent that the slack of lead 100 from coming out from this lead casket 310.

In addition, but preferably optionally, second end of this auxiliary conductor guiding piece 320 is downward-sloping with predetermined angle, as shown in Figure 8.Therefore, when electric component with respect to main body 10 forward during sufficient movement, the slack of lead 100 can not come out from this lead casket 310.

This auxiliary conductor guiding piece 320 is arranged on the back space place of this container 20, and lead 100 is covered by this auxiliary conductor guiding piece.Therefore, when promptly box lunch door 13 was opened fully, lead 100 was not exposed to the outside of this refrigerator yet, and as shown in Figure 8, thereby the user can not be shocked by electricity in contact wire 100, and lead 100 can not be damaged yet.

But first end of this auxiliary conductor guiding piece 320 makes this auxiliary conductor guiding piece 320 can rotate around this pivot by being pivotally connected to door 13 or described element preferably optionally.Then, when lead 100 fluffed according to the motion of door and strains, this auxiliary conductor guiding piece 320 can rotate in predetermined angular range.Like this, when door 13 motion, this auxiliary conductor guiding piece 320 not with the movement interference of lead 100.Therefore, lead 100 is not damaged by this auxiliary conductor guiding piece 320.

When door 13 was opened, because lead 100 is tightened up, this auxiliary conductor guiding piece 320 relatively rotated up near level.Become too hard at this pivot so that under the situation that can not be rotated down, when door 13 was closed fully, this auxiliary conductor guiding piece 320 may bump against refrigerator main body 10.In order to prevent this problem, can also comprise projection 330 according to this structure of second embodiment of the invention, as shown in Figs. 8 to 11.

Projection 330 is arranged on that this is indoor, promptly in the refrigerating chamber 11.More particularly, this projection 330 can be stretched out from the inner surface of this refrigerating chamber 11.Alternatively, this projection 330 can be stretched out from track 40, more particularly, stretches out from first track 41, as shown in Figure 9.When door 13 when closing fully, the top of these projection 330 these aid in guide parts 320 of contact more particularly, contacts the top of second end.Therefore, when door 13 projection 330 when closing fully forces this aid in guide part 320 to be rotated down, bump against this main body 10 to prevent this auxiliary conductor guiding piece 320.
