Below with reference to Fig. 1-5, describe according to the refrigerator of the embodiment of the present invention and drawer appliance thereof.
As shown in Figure 1, according to the refrigerator of the embodiment of the present invention, comprising: casing 1, drawer appliance 2, refrigerator power supply and master control borad (not shown).
Particularly, have chamber between refrigeration in casing 1, refrigerator power supply is located at respectively on casing 1 with master control borad and refrigerator power supply is connected with control board.
The linkage of the coil holder 22 of drawer appliance 2 respectively with the rear end of drawer 21 and refrigeration between the rear wall of chamber be connected, the linkage that power signal line 23 passed and passed coil holder 22 from the rear wall of chamber between freezing is connected to the electrical appliance of drawer 21.Thus, a part for power signal line 23 is in bindiny mechanism, and another part is located on drawer 21.
In drawer 21 push-and-pull processes, the part of power signal line 23 in linkage can fold and launch and can keep length constant along with the folding and expansion of linkage, and therefore the total length of power signal line 23 also remains unchanged in whole process.
Thus, according to the refrigerator of the embodiment of the present invention, by the linkage of coil holder 22, enough continued powers and transfer of data in the process of push-and-pull drawer 21, and effectively avoid changing or power signal line wearing and tearing, the knotting causing of move even ruptured due to the length of power signal line.In addition, power signal line 23 can play a protective role to its epidermis by being located in bindiny mechanism.Finally, the refrigerator structure of the embodiment of the present invention is simple and be convenient to manufacture.
Other formations of the refrigerator of the embodiment of the present invention can be well known by persons skilled in the art, do not repeat them here.
As shown in the Fig. 5 of Fig. 2-5, according to one embodiment of present invention, drawer appliance 2 comprises: drawer 21, coil holder 22 and power signal line 23.
Particularly, coil holder 2 consists of collapsible and extensible linkage.Linkage comprises multiple end to end connecting rods, between adjacent connecting rod, by bearing pin, is connected pivotly with axis hole, therefore between connecting rod, can be drawn out and push and launch and fold with drawer 21.
Connecting rod is hollow pipe, and power signal line 23 passes hollow pipe and extends in multiple connecting rods, to fold and launch with the folding and expansion of linkage, therefore the length of power signal line 23 can remain unchanged and knotting and wearing and tearing can not occur.
Preferably, hollow pipe is flat tube.
Thus, according to the drawer appliance 2 of the embodiment of the present invention, by the linkage of coil holder 22, drawer 21 along can continued power and transfer of data in fore-and-aft direction reciprocating motion process, and effectively avoid because the length of power signal line changes or power signal line the move wearing and tearing, the even fracture of knotting that cause.In addition, power signal line 23 can play a protective role to its epidermis by being located in bindiny mechanism.Finally, the drawer appliance 2 of the embodiment of the present invention simple in structure and be convenient to manufacture and install.
As in Figure 3-5, according to one embodiment of present invention, the outer bottom of drawer 21 is provided with the groove 212 of the rear end face 211 that extends to drawer 21, linkage is connected to the rear end of drawer 21 at groove 212 places, being linkage extends along groove 212 in the corresponding so that one end of power signal line 23 of groove 212 with the connection of drawer 21, until be connected with the electrical appliance of drawer 21.Groove 212 can extend to rear end face 211 so that electric power data line 23 extends to the front panel 213 of drawer 21 from the front bulkhead of drawer 21 213.
Electric power data line 23 can be divided into the two parts that are positioned at connecting rod and groove 213.The length that is located at part in connecting rod due to electric power data line 23 can not change because of the push-and-pull campaign of drawer 21, and the part that electric power data line 23 is located in groove 212 is moved with respect to drawer 21 nothings when drawer 21 is drawn out and pushes, and therefore the length of electric power data line 23 can not change with the motion of drawer 21.Electric power data line 23 parts are located in groove 213 can avoid drawer 21 come in contact with electric power data line 23 at the volley and the epidermis of electric power data line 23 is also played a protective role.
Linkage can comprise first connecting rod 221 and second connecting rod 222.Second end (being front end) of first connecting rod 221 is connected by bearing pin pivotly with the first end (being rear end) of second connecting rod, and the second end of second connecting rod 222 (being front end) is connected by bearing pin pivotly with the rear end of drawer 21, between the first end of first connecting rod 221 (being rear end) and refrigeration, the rear wall of chamber is connected pivotly by bearing pin.First connecting rod 221 and second connecting rod 222 equal in length.
According to one embodiment of present invention, linkage is quadric chain and comprises first to fourth connecting rod 221,222,223 and 224, and four connecting rods 221,222,223 and 224 join end to end by bearing pin successively.Linkage is connected to the rear end of drawer by the bearing pin between second connecting rod 222 and third connecting rod 223, be connected to the rear wall of chamber between refrigeration by the bearing pin between first connecting rod and the 4th connecting rod.Wherein first and the 4th connecting rod 221,224 equal in length and second and third connecting rod 222,223 equal in length so that the pull-out distance of drawer 21 and push distance and be subject to the restriction of a side connecting rod (the first and second connecting rods 221,222 or the third and fourth connecting rod 223,224).
Quadric chain can make the folding and expansion between connecting rod more flexible and stable than two linkages, and can hold more power control line 23.
As shown in Figure 4 and Figure 5, preferably, the length of first to fourth connecting rod 221,222,223 and 224 is equal to each other so that quadric chain is formed as parallelogram (being rhombus or square) linkage.By rhombus or square linkage, can guarantee that the bending angle of power signal line 23 when folding is less thus, be conducive to the long-term use of power signal line 23.
As shown in Figure 4, between refrigeration indoor pull-out drawer 21 processes, because the bearing pin between second connecting rod 222 and third connecting rod 223 is drawn forward movingly, quadric chain is unfolded; As shown in Figure 5, between refrigeration in the indoor process that pushes drawer 21, because the bearing pin between second connecting rod 222 and third connecting rod 223 is pushed rearward movingly, quadric chain is folded.
In the description of this description, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present invention or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And specific features, structure, material or the feature of description can be with suitable mode combination in any one or more embodiment or example.
Although illustrated and described embodiments of the invention, those having ordinary skill in the art will appreciate that: in the situation that not departing from principle of the present invention and aim, can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is limited by claim and equivalent thereof.
