Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature storage equipment, in particular to a drawer opening structure and a refrigerator. Background Art

[0002] Most of the currently used refrigerators are composed of a door body and a box body. The door body is installed on the upper side of the box body, and the opening method is single. Moreover, the internal accommodation space of the box body is integrated. For the integrated refrigerator, there is a problem that it is not convenient to take items in the bottom space. Every time a user takes an item at the bottom, they need to take out the items above before they can take out the items at the bottom, which not only consumes manpower and time, but also has a long door opening time and a large loss of cold quantity, resulting in high power consumption.

[0003] In the prior art, a refrigerator with a grille and a drawer is provided. The drawer is arranged below the box body, and the items placed in the drawer can be taken out by pulling out the drawer, thus solving the problems of long door opening time, large loss of cold quantity and high power consumption when taking items at the bottom. However, after the drawer is pulled out, since the drawer is arranged at a relatively low position, people need to bend down or squat down to take out the items, which will still lead to the problem of inconvenient taking.

[0004] In view of this problem, a refrigerator is provided in the prior art, including a drawer and a box body. The drawer is inclined on the box body so that the drawer can be pulled out upward for people to take out items conveniently. However, when the drawer is pulled out, it will automatically reset under the action of gravity, so that people need to keep pulling the drawer to apply a force to keep the drawer in the open state, and there is still the problem of inconvenient taking, and the user experience is poor.

[0091] A positioning structure is further provided on the moving guide rail 400. The positioning structure is connected to the limiting buckle 518 for positioning the limiting buckle 518 at a first position. When the limiting buckle 518 is in the first position, the second end of the limiting buckle 518 slides along the moving slot 510.

[0092] Specifically, as Figure 4 and Figure 7 shown, the positioning structure includes a spring clip 513. A first positioning groove 514 and a second positioning groove 515 are provided at the first end of the limiting buckle 518. The spring clip 513 is snapped into the first positioning groove 514 for positioning the limiting buckle 518 at the first position. When the spring clip 513 is located in the second positioning groove 515, the limiting buckle 518 is in a rotatable state.

[0093] Furthermore, as Figure 5 shown, a first inclined surface structure 516 is provided at the first end of the moving slot 510. The first inclined surface structure 516 is used to drive the limiting buckle 518 to rotate when the limiting buckle 518 slides along the moving slot 510, so that the spring clip 513 is snapped into the first positioning groove 514.

[0094] A second inclined surface structure 517 is provided at the second end of the moving groove 510. The second inclined surface structure 517 is used to drive the limit buckle 518 to rotate when the limit buckle 518 slides along the moving groove 510, so that the spring card 513 disengages from the first clamping groove 514.

[0095] The freezer drawer 200 of the freezer provided by the present utility model has at least the following three states:

[0096] A. As Figure 9 shown, when the limit buckle 518 moves along the moving groove 510 to the limit groove 511, the limit buckle 518 is snapped into the limit groove 511. At this time, the spring card 513 is always located in the second clamping groove 515; even when the freezer drawer 200 is pulled to move the limit buckle 518 between the two limit grooves 511, the spring card 513 is always located in the second clamping groove 515;

[0097] B. As Figure 10 shown, when the limit buckle 518 moves along the moving groove 510 to the first inclined surface structure 516 at the first end of the moving groove 510, the first inclined surface structure 516 drives the limit buckle 518 to rotate, the second end of the limit buckle 518 rises, and the spring card 513 is snapped into the first clamping groove 514 to position the second end of the limit buckle 518 at the first position. At this time, the position of the limit buckle 518 is fixed at the first position. When the freezer drawer 200 is pushed, the limit buckle 518 slides along the moving groove 510 and will not be snapped into the limit groove 511;

[0098] C. As Figure 11 shown, when the limit buckle 518 moves along the moving groove 510 to the second inclined surface structure 517 at the second end of the moving groove 510, the second inclined surface structure 517 drives the limit buckle 518 to rotate, the second end of the limit buckle 518 moves downward, and the spring card 513 returns to the first clamping groove 514. At this time, the freezer drawer 200 is in a closed state. When the user opens the drawer again, the limit buckle 518 can be snapped into the limit groove 511 again, and the freezer drawer 200 can continue to be positioned through the limit groove 511.
