One opposite house 12 is connected on the refrigerator main body 10 by hinge.This door 12 rotates to open and close refrigerating chamber with respect to this main body 10 around this hinge.Door 13 is arranged on main body 10 bottoms and is used to open and close freezing Room 11 in this main body 10 bottoms.Door 13 moves forward and backward with respect to main body 10, and door 12 is around hinge through.Therefore, do not need hinge or pivot that door 13 is connected with main body 10.
As depicted in figs. 1 and 2, a plurality of tracks 40 are arranged between this main body 10 and the door 13, are used for guiding reposefully this slip of 13.This track 40 is arranged on the both sides of door 13, and comprises first track 41 that is fixed in main body 10 and second track 42 of fixing this 13 back.Alternatively, the support that fixedly secures can be set in door 13 back, and second track 42 can be fixed in this support.
At least one container 20 that is used for depositing food within it is arranged on this refrigerating chamber 11 of refrigerator bottom, and as depicted in figs. 1 and 2, and at least one drawer 15 is arranged on the top of this container 20 in this refrigerating chamber 11, as shown in Figure 1.This container 20 is along with the motion of door 13 is moved forward and backward with respect to main body 10, and moving with moving of door 13 of drawer 15 is irrelevant.For the convenience of the users, this container 20 can raise automatically when door 13 is opened fully.In one embodiment, lifting device 30 is fixed in this rear surface of 13, shown in Fig. 2 and 3.This lifting device 30 is fastened to door 13 rear surfaces, and container 20 is placed on this lifting device 30 and supported by this lifting device.
Fig. 3 is shown specifically the structure of this lifting device.Describe the structure of this lifting device 30 in detail below with reference to Fig. 3.As shown in Figure 3, this lifting device 30 comprises the lifter 31 that container 20 is settled thereon, and a pair of lifting track 32 that is fixed in door 13 is used to guide the lifter motion of this lifter 31, and the driver element that is used for promoting automatically this lifter 31.
This driver element comprises that at least one can be with respect to the arm 37 of door 13 rotation, motor 34, the driving shaft 36 that is connected with this arm 37 with a gear assembly 35 that is connected of this motor 34, with this gear assembly 35, to rotate this arm 37.In an illustrated embodiment, there are two arms 37 to be arranged on this basifacial both sides, 13 backs.Motor 34 is fixed in door 13 back and is arranged between these two arms 37.This motor 34 is controlled by the refrigerator controller (not shown), or handles the submaster controller (not shown) control of this motor 34 by being independent of this controller.
At the top that promotes track 32 upper level sensor 38a is arranged, and following level sensor 38b is arranged in the bottom that promotes track 32, this upper level sensor 38a and following level sensor 38b promote track 32 tops or floor detection lifter 31 at this respectively, and signal is sent to controller.Controller stops motor 34 after receiving this signal.Therefore, the range of movement of lifter 31 is restricted and prevents that lifter 31 breaks away from this lifting track 32.Alternatively, the upper limit position switch (not shown) can be arranged and the lower position switch (not shown) can be arranged at the top of this lifting track 32 in the bottom of this lifting track 32.By the power supply of sever supply motor 34, this upper limit position switch and lower position switch can directly stop motor 34.
In one embodiment, when door 13 has just been opened or after door 13 opened a preset time fully, this lifter 31 promoted automatically fully, and just be pushed slightly so that when closing when 13, this lifter that promotes fully 31 moves downward automatically.Alternatively, the control button (not shown) can be arranged on this door 12 or 13, so that the user can control this lifting device 30 by pushing this control button.
When control button is depressed or when the door 13 open a scheduled time fully after, motor 34 is started working.Then, gear assembly 35 turns round with rotating driveshaft 36 by motor 34.Because driving shaft 36 rotates, arm 37 begins to rotate and the roller 37a in these arm 37 ends begins to raise rolls on the bottom surface of lifter 31 simultaneously.Therefore, this lifter 31 is with settling container 20 thereon to begin to raise.When lifter was promoted fully, upper level sensor 38a detected this lifter 31 and sends a signal to controller.After received signal, controller stops motor 34, and therefore stops the lifter motion of this lifter 31.At this moment, mesh and be supported by it at the roller 37a of this arm 37a end and the side of this inclined-plane projection 31a.Therefore, since the counter motion of this arm 37 of causing of gravity and this lifter 31 can prevent with moving downward of container 20 with being had.
Simultaneously, after taking out food or put new food into container 20 from container 20, the user pushes control button or slightly door 13 is pushed to the main body 10 of this refrigerator.Then, its axle of motor 34 reverse rotations.Therefore, this lifter 31 and container 20 move downward together.Under the situation that this lifter 31 and container 20 land fully, this time level sensor 38b and controller stop to move downward of this lifter 31.Then, the user can put container 20 into this refrigerating chamber 11 by door 13 being pushed to this main body 10.
As mentioned above, with this 13 together can be relative with this lifting devices 30 of this refrigerator main body 10 motions by power supply 16 (Fig. 2) supply of electrical energy in this refrigerator main body 10.Perhaps, possible is that other electric components such as display floater or touch pad that are arranged on the door 13 need electric energy.And it also is possible being arranged on the door 13 such as communicating by letter with controller with other electric components such as sensor that send signal.In these cases, just need make that movably the power supply 16 in electric component and the main body 10 and at least one of controller link to each other with respect to main body 10 by the lead of for example feed cable or signal cable.
One embodiment of the present of invention provide a kind of lead 100, being electrically connected with power supply 16 or controller in this main body 10 with respect to these main body 10 movable these electric components.This lead 100 comprises at least a in feed cable and the signal cable.When electric component when first direction moves, this lead 100 is adjustable along the length of first direction by coiler device.In other words, when door 13 is closed, shorten the length of this lead automatically according to this coiler device of the embodiment of the invention, and when door 13 is opened, the length of this lead of automatic increase.In an illustrated embodiment, this first direction is a horizontal direction.But should be noted that the present invention can be used for electric component and the door along its any direction of moving.
When electric component or door 13 when its first direction moves, this coiler device is by reeling or launching lead 100 and in the length of first direction adjusted lead 100.In addition, this coiler device applies pulling force along first direction to this lead 100.Thereby can reduce of the danger of the lax and quilt of this lead 100 significantly according to the miscellaneous part damage of the refrigerator of the embodiment of the invention.
The present invention illustrates the various embodiment of coiler device, and is extremely shown in Figure 11 as Fig. 2 and Fig. 4.As shown in drawings, all embodiment of the present invention illustrate spool, when electric component when first direction moves, be used for reeling or launching this lead 100.But, when electric component among each embodiment and door when first direction moves, the mechanism that rotates this spool automatically in each embodiment is different.
With reference to figure 2 and Fig. 4 to Fig. 7, comprise that according to the coiler device 200a of first embodiment of the invention lead 100 can and provide the elastic component 220 of revolving force around the spool 210 of its coiling for this spool 210 with elastic force.This spool 210 for example has cylinder form and when these spool 210 rotations, this lead 100 is reeled around the external peripheral surface of this cylindrical spool 210.This spool 210 for example has the space within it, and elastic component 220 is arranged in this space, as shown in Figure 4.This elastic component 200 can comprise wind spring, and it assembles elastic energy within it according to rotatablely moving of this spool 210 when being reeled or launching.
First end of this elastic component 220 can be connected in this spool 210 and second end of this elastic component 220 can be connected in this main body 10, and vice versa.Alternatively, first end of this elastic component 220 can be connected in this spool 210 and second end of this elastic component 220 can connect the miscellaneous part that separates with this spool 210, for example, track 40, vice versa.In addition, the housing (not shown) of the part of this lead 100 of surrounding this spool 210 and reeling around this spool 210 can be arranged in this refrigerator, and this elastic component 220 is connected in this spool 210 and this housing.
When door 13 is closed since this electric component promptly power supply 16 or the distance between the controller in this lifting device 30 and this main body 10 is close, so this lead 100 twines multi-turns around this spool 210, as shown in Figure 5.In addition, except the part of twining around this spool 210, the contraction in length of these lead 100 along continuous straight runs is so reduce the lax of this lead 100 significantly.At this moment, 220 pairs of these spools 210 of the elastic component in the illustrated embodiment continue to apply weak elastic force with along this spool 210 of counter rotation.But this spool 210 is not rotated by this elastic force, because this lead 100 is fully strained.Therefore, when door 13 was closed, this elastic component 220 was strained these leads 100 and towards this chamber this lead 100 is applied pulling force along horizontal direction, thereby reduced the lax of this lead 100 effectively.
When door begins to be opened and when leaving this main body 10, the lead 100 of reeling around this spool 210 begins to launch.At this moment, except that wound portion was divided, the length of the along continuous straight runs of lead 100 was elongated, and spool 210 rotates along clockwise direction simultaneously, and this elastic component 220 is assembled elastic force therein when this spool 210 is rotated in a clockwise direction.When door 13 is opened fully, the length maximum of these lead 100 along continuous straight runs, and the elastic energy of this elastic component 220 and elastic force are also maximum.At this moment, because 220 pairs of spools 210 of elastic component continue to apply and make the elastic force of this spool 210 along counter rotation, this lead 100 is tightened up and also it is applied pulling force.Therefore, though this lead 100 extends fully, can reduce the lax of this lead 100 significantly.
On the contrary, when door 13 began to close, along continuous straight runs was eliminated the power that this lead 100 is pulled away from this main body.Because elastic component 220 keeps along counter rotation this spool 210 with bigger elastic force, so spool 210 is along counter rotation, and lead 100 begins to twine around this spool 210.When door 13 was closed, because the spool 210 that is rotated by elastic component 220 tightly draws this lead 100, this lead 100 was tightened up and this lead is applied pulling force.Therefore, when closing, door 13 can reduce the lax of this lead 100 significantly.
Exposing this lead also is fine.But in order further to protect this lead 100, preferably this lead 100 is surrounded by the miscellaneous part of this refrigerator.In one embodiment, this lead 100 is arranged to the logical track 40 of leading this 13 motions that connects, thereby this lead 100 is besieged and protected reliably.More particularly, this first track 41 and second track 42 have Hollow Pillar shape respectively.First track 41 is in vertical insertion second track 42 of second track 42, and vice versa.This lead 100 is arranged to pass simultaneously this first and second track 41 and 42, as shown in Figure 6.
Alternatively, the lead guiding piece 50 that is independent of track 41 and 42 can be arranged in the refrigerator according to first embodiment, and lead 100 is arranged to pass this lead guiding piece 50, as shown in Figure 7.According to electric component is the motion of lifting device 30 or the motion of this door 13, and this lead guiding piece 50 vertically is extending and withdrawal along it.
More particularly, 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.When door 13 was closed, because this first guiding piece 51 being along vertically being inserted in this second guiding piece 52 of this second guiding piece 52 and can be overlapping with this second guiding piece 52, 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.Therefore very similar first and second tracks 41 of these structures and 42 structure, will be removed about the more detailed description of lead guiding piece 50 structures.
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 reliably 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.
Simultaneously, as Fig. 2 and shown in Figure 5, in first embodiment, this coiler device 200a can be arranged in the refrigerating chamber 11.Alternatively, the coiler device 200a according to first embodiment of the invention can be arranged in the mechanical part chamber 17, as shown in Figure 7.But the invention is not restricted to above-mentioned example.For example, though these examples do not illustrate in the accompanying drawings, this coiler device 200a can be arranged in the track 40 or in the lead guiding piece 50.
As implied above, regulate the length of this lead 100 according to this coiler device 200a of first embodiment of the invention automatically according to the motion of electric component or door 13 except that the along continuous straight runs of wound portion branch.In addition, regardless of the position of this electric component or door 13, this coiler device 200a always strains this lead 100 and this lead 100 is applied pulling force.The danger that therefore can reduce the lax of this lead 100 effectively and be damaged by this refrigerator miscellaneous part.
Simultaneously, to Figure 11, comprise spool 260 and the mechanism that is used to rotate this spool 260 with reference to figure 8 according to the coiler device 200b of second embodiment of the invention.When electric component or 13 whens motion of door, this mechanism makes this lead 100 be winding to the external peripheral surface of this spool 260 or launches from it according to the motion of electric component or door 13 clockwise or this spool 260 of inhour rotation.
When electric component or door 13 travelled forward with respect to this main body, this lead 100 can launch from this spool 260, and the mechanism that is illustrated among the embodiment of this spool 260 rotates along clockwise direction simultaneously.On the contrary, when electric component or door 13 moved backward with respect to this main body 10, this lead 100 can be reeled around this spool 260, and this spool 260 is rotated along counter-clockwise direction by this mechanism simultaneously.The detailed structure of spool 260 and this mechanism will be discussed in more detail below with reference to above-mentioned accompanying drawing.
This spool 260 has, for example, hollow cylinder form, as shown in Figure 9, and lead 100 is arranged to pass this spool 260.On this spool 260, slit 265 is set.This cylindrical spool 260 is passed along the diametric(al) of this spool 260 in this slit 265, and this lead 100 is by this slit 265.This slit 265 can have circular (not shown) or elongated flute profile as shown in Figure 9.In an illustrated embodiment, this spool 260 has two slits on the spool circumference, and lead passes two slits along the diameter side of this spool 260, and the circumference around this spool when spool rotates twines.
This spool 260 can be arranged on the middle part of this lead 100 as shown in Figure 8.In this case, when spool 260 rotations, this lead 100 twines in both sides around this spool 260 simultaneously.Then, when spool 260 rotation half-turns, this lead 100 twines a circle around this spool 260.
This mechanism can comprise tooth bar 251 and the pinion 255 that is connected in this spool 260 and meshes with this tooth bar 251, as shown in Figure 9.This tooth bar 251 is along electric component and door 13 travel direction settings.A plurality of tooth 251a are on a side that vertically is arranged on this tooth bar 251 of this tooth bar 251, and pinion 255 has tooth 255a a plurality of and tooth 251a engagement, as shown in Figure 9.Therefore, when tooth bar 251 during along the vertically moving of this tooth bar 251, these pinion 255 rotations.
