For example, drawer unit 30 has door-plate 32 and container basket 30a, and wherein said door-plate 32 is used for the open front of the secondary storeroom 23 of On/Off, and described container basket 30a is placed between the track element 40 to hold food to be stored.Handle 34 can be arranged on door-plate 32 places, to be used for On/Off drawer unit 30 easily.According to an embodiment, door-plate 32 is integrally formed with one another with container basket 30a.According to another embodiment, door-plate 32 is configured to can be connected each other with container basket 30a/and detachable.
Each track element 40 all is set between inner casing 2 and the drawer unit 30 so that drawer unit 30 slides with respect to inner casing 2.As shown in fig. 1, pair of tracks unit 40 is set up and separates each other with certain spacing.Selectively, also can be provided with two pairs or more to track element.
For example, each track element 40 all has the guide rail 41 that is connected with support section 7, also has slide rail 42 and 43, and described slide rail 42 and 43 combines with guide rail 41 and drawer unit 30 and can move slidably with respect to guide rail 41.According to an embodiment, guide rail 41, slide rail 42,43 are separated by rolling element 44.Slide rail 42 and 43 quantity can change as required.For example, according to an embodiment, as shown in Figure 2, under the situation that two slide rails are set, promptly under the situation that first slide rail 42 and second slide rail 43 are set up, slide rail was drawn out of by two steps.That is to say that when drawer unit 30 was drawn out of, first slide rail 42 was drawn out of along guide rail 41, second slide rail 43 is drawn out of along first slide rail 42 then.If be provided with the slide rail of three or more, the extraction of drawer unit 30 distance can increase pro rata with the number of slide rail so.According to the embodiment of Fig. 2, the slide rail 43 that is drawn out of at last is connected with support 31 by fixture 33.Be to be understood that embodiments of the invention are not limited to the moving in succession of guide rail 42 and 43.In other words, guide rail 42 and 43 also can move simultaneously.
With reference to Fig. 2 and Fig. 3 A, support section 7 is formed at inner casing 2 and sentences supporting track unit 40.Support section 7 bears track element 40 and the load of the drawer unit 30 that supported by track element 40, acts on bound fraction 50 so support section 7 prevents the load of track element 40 and drawer unit 30.Therefore, track element 40 can move along the rail-guided part 63 that will illustrate after a while reposefully.
In order to prevent that the spacing between the foam components 4 and track element 40 changes when foam components 4 shrinks at low temperatures, bound fraction 50 combines track element 40 movably with support section 7.
According to an embodiment, bound fraction 50 comprises a plurality of first combined holes or the shrinkage pool (pocket) 51 that is formed on the support section 7; Be formed on the track element 40 and corresponding to a plurality of second combined holes 52 of first combined hole 51; With a plurality of screws 60, each described screw 60 passes second combined hole 52 and combines with first combined hole, 51 screw threads.The number of first combined hole 51 and second combined hole 52 can change as required.
Rail-guided part 63 is positioned between main part 61 and the head part 62, and when shrinking with convenient foam components 4, guide rail 41 can relatively move on the direction opposite with inner casing 2 shrinkage directions.That is, if inner casing 2 shrinks, guide rail 41 still can remain on the absolute position.In other words, if inner casing 2 shrinks, guide rail 41 does not move with inner casing 2.According to such structure, though foam components 4 shrinks, the distance between the track element 40 still remains unchanged.According to an embodiment, screw 60 can be formed the outer dia of the outer dia of rail-guided part 63 greater than main part 61.
The length of rail-guided part 63 can change according to the amount of contraction of foam components 4 and inner casing 2.For example, if the width of the inner casing 2 of refrigerating chamber 21 has increased 3-4mm owing to the contraction of foam components 4 and inner casing 2, the length that screw 60 can be designed as rail-guided part 63 is 1.5 to 2mm, and this is foam components 4 and inner casing 2 amounts of contraction half.
Attaching parts 70 (see figure 1)s are configured to connect the end of pair of brackets 31, and wherein track element 40 combines with described pair of brackets 31, and the distance between the track element 40 is held thus.Attaching parts 70 can be by there not being flexible any materials to make.According to such structure, the support 31 that combines with track element 40 by fixture 33 combines with door-plate 32 by its end, and the other end of support 31 is connected with attaching parts 70, and the distance between the track element 40 can be held thus.
Hereinafter, with reference to Fig. 3 B and Fig. 3 C operation of the present invention is described.
At first, with reference to Fig. 3 B, the main part 61 of screw 60 is passed second combined hole 52 that is formed on the guide rail 41 and is combined with first combined hole 51 on being formed on support section 7.At this moment, because the outer dia of rail-guided part 63 is greater than the outer dia of main part 61, therefore rail-guided part 63 is passed second combined hole 52, but is not contained in first combined hole 51.The shape of second combined hole 52 is corresponding with the shape of head part 62.In this embodiment, because screw 60 also is provided with rail-guided part 63 between main part 61 and head part 62, under normal room temperature, head of screw part 62 is identical with the length of rail-guided part 63 from the outstanding length in the surface of guide rail 41.
Below with reference to Fig. 3 C, under the situation that the refrigerating operation for storeroom 23 and 24 begins, foam components 4 and inner casing 2 shrink, so the surface of inner casing 2 moves to position A ' from position A (initial position).At this moment, because guide rail 41 has the movably surplus with the equal in length of rail-guided part 63, so guide rail 41 do not move along with the contraction of inner casing 2, but remains on its initial position.Therefore, though inner casing 2 shrinks and the interval that forms between the apparent surface of inner casing 2 of storeroom 23 and 24 increases when refrigerating operation is performed, the interval between the pair of tracks unit 40 remains unchanged, and has therefore strengthened the slip mobility of drawer unit 30.
Below with reference to Fig. 4 explanation refrigerator according to a second embodiment of the present invention.
