Technical Field

The utility model relates to the technical field of household appliances, in particular to a refrigeration appliance.

Background

Some known refrigeration appliances have a drawer assembly whose cover is slidable relative to the drawer and is moved progressively upwards to open the drawer or downwards to close the drawer during the sliding movement. For example, the refrigeration appliance has obliquely arranged rails on both sides and feet on both sides of the cover plate, and a force is applied to the cover plate so that the feet respectively slide on the rails from the lower end to the upper end, whereupon the cover plate is gradually raised to open the drawer. In some cases, the difference exists in the dimensional tolerance or roughness of the rails or the rails, or the direction of the force pushing the cover plate to move is not consistent with the direction of the rails, which may cause the legs on both sides of the cover plate to move asynchronously, so that one side of the cover plate exceeds the highest position of the rails and the other side of the cover plate does not reach the highest position. Then, when the legs slide on the rails from the high end to the low end, which tends to cause the cover to close the drawer, the sides of the cover are of inconsistent height and do not close the drawer.

SUMMERY OF THE UTILITY MODEL

It is an aspect of embodiments of the present invention to provide an improved refrigeration appliance having a cover that is restricted from moving from a position for closing a drawer to a position for opening the drawer, thereby promoting a uniform height across the cover, and thus a uniform height across the cover when the cover is moved from the open position to the closed position, reducing the probability of a defective closed condition.

Detailed Description

The technical solutions of the present application are described clearly and completely by the following specific examples, and it is obvious that the described examples are some, but not all, of the examples of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The present invention provides one or more refrigeration appliances having a drawer assembly 100.

The refrigeration appliance can be a household appliance such as a household refrigerator, a freezer or a wine cabinet and the like for providing storage environments such as low-temperature food, wine and the like for users. It can be a single door, or multiple doors; the cooling type can be air-cooled, or direct cooling, or mixed cooling; the vertical type or horizontal type can be adopted, and the achievement of the purpose of the utility model is not influenced. On the basis, the whole structure of the refrigeration appliance is omitted.

The drawer assembly 100 can be used to store objects, such as fish, vegetables and fruits, drinks, dry goods, etc.

Fig. 1 shows an elevation view of a drawer assembly 100 of a refrigeration appliance in an embodiment of the utility model. Fig. 2 further illustrates a partial exploded view of the embodiment of fig. 1, wherein the drawer body 20 is hidden.

The drawer assembly 100 may include a body and a cover 10. The drawer body 20 is in a box shape with one side open, and a cavity for storing articles is formed inside the drawer body. The cover plate 10 covers the open position above the drawer body 20, and can move relative to the drawer, for example, when the cover plate 10 covers the open position, the cavity is closed, and at this time, the cover plate 10 is in the covering position; the cover 10 may also be removed from the closed position so that the cavity is in communication with the exterior, in which case the cover 10 may be in the open position. As will be understood by those skilled in the art, when the cover plate 10 is covered on the drawer body 20, the cavity is not exchanged with the external gas, and the temperature and/or humidity inside the cavity is high; when the cover 10 is in the open position, the interior of the chamber is exchanged with the exterior, and the temperature and/or humidity within the chamber is reduced, so that such a drawer assembly 100 may be used in a refrigerator requiring humidity and/or temperature regulation.

The drawer assembly 100 has opposite first and second ends 1, 2, for example one end forward and the other end rearward.

The refrigerator further comprises rails 321 and 322 with inclined extensions 32, and supports 121 and 122 provided on the cover plate 10, the supports 121 and 122 being slidable on the rails 321 and 322. When the supports 121 and 122 are located at the lower ends of the rails 321 and 322, such as the position B, the cover 10 contacts the drawer body 20 to close the cavity, i.e. the cover 10 is in the closed position. When the cover 10 slides along the rail toward the upper end, the distance between the cover 10 and the drawer body 20 is gradually increased, that is, the cover 10 is in the open position, such as the a position.

In a specific embodiment, as shown in fig. 1, the inclined extension 32 is inclined upward from the first end 1 to the lower end, and if the direction in which the first end 1 is directed to the second end 2 is defined as a first direction, the cover plate 10 is gradually raised in height when moving from the covering position along the first direction; when the cover 10 is moved from the open position against the first direction, the height of the cover 10 is gradually lowered.

The movement of the cover 10 in the first direction may be a user pushing the cover 10 by hand, or may be a user pushing by using other mechanical structure, an electric driving structure, so long as a force substantially along the first direction is applied to the cover 10, the cover 10 may move in the first direction under the force to open the drawer body 20.

The movement of the cover plate 10 against the first direction can be achieved by its own weight. When the cover 10 is in the open position and the cover 10 is at the higher end of the track, when the external force applied to the cover 10 is removed, there will be a component force parallel to the inclined extension 32 to urge the cover 10 to slide along the tracks 321 and 322 to the lower end to the closed position.

A first stop portion 33 is disposed at the upper end of the inclined extension section 32, and when the supporting portion moves to the upper end of the inclined extension section 32 along the first direction, the supporting portion is stopped by the first stop portion 33, so that the supporting portion is limited from moving along the first direction.

Differences in tolerance, wear or roughness during manufacturing and use of the support portions 121 and 122 and the rails 321 and 322 may affect the unsynchronized sliding of the support portions 121 and 122 on the rails 321 and 322, such as when one side of the cover plate 10 has reached the upper end of the rails and the other side has not, and if the movement is continued, the side that first reached the upper end will pass over the upper end. This results in subsequent movement against the first direction being not smooth and even the side which reaches the upper end first cannot be completely returned to the closed position. A similar technical problem may also arise if the direction of the force pushing the cover plate 10 to move in the first direction does not exactly coincide with the first direction.

By adding the first stopping portion 33, the supporting portions 121 and 1222 which reach the upper end of the inclined extension 32 first are blocked by the first stopping portion 33, and the movement of the supporting portions is limited to continue along the first direction. When the cover plate 10 continues to move in the first direction, the supporting portion on the other side of the cover plate 10 may reach the upper end, that is, the heights of both sides of the cover plate 10 are uniform. In this way, the problem of the cover plate 10 being displaced against the first direction without the sides being congruent and thus not being able to close well can be avoided.

In a possible embodiment, the rails 321 and 322 may include a first rail 321, and the first stopper 33 is disposed at an upper end of the inclined extension 32 of the first rail 321. Also, the first rail 321 is closer to the second end 2 of the drawer assembly 100. When the cover plate 10 moves along the first direction, the closer the cover plate 10 is to the second end 2, the more obvious the front-back inconsistency of the two sides is, the larger the difference is, the closer the first stopping portion 33 is to the second end 2, and the better the technical effect is.

In a possible embodiment, a second stop 341 is provided at the lower end of the inclined extension 32 of the first rail 321 to prevent the support portion 121 from sliding further downward.

Further, the rails 321 and 322 include a second rail 322 near the first end 1, and a second stopper 342 is disposed at a lower end of the inclined extension 32 of the second rail 322 for preventing the support portion 122 from sliding downwards.

In a possible embodiment, the rails 321 and 322 include a second rail 322 near the first end 1, and a first stop 33 is disposed at the upper end of the inclined extension 32 of the second rail 322 to prevent the support portion 122 from sliding upwards.

In a possible embodiment, the refrigeration appliance further comprises an adjusting portion 40, wherein the adjusting portion 40 is used for adjusting the cover plate 10 so that the cover plate 10 moves upwards to an open state or downwards to a closed state; the adjustment portion 40 is closer to the first end 1 and the first rail 321 is closer to the second end 2. The larger the distance between the adjusting portion 40 and the first blocking portion 33 is, the more slightly the front and back inconsistency of the two sides is, and the better the technical effect of the present invention is.

The regulating portion 40 may be an electric transmission structure. As shown in fig. 2, the adjusting portion 40 includes a motor 43, an eccentric wheel 41, and an interference portion 42 on the cover plate 10. The motor 43 and the eccentric wheel 41 are arranged in a static way relative to the drawer body 20, and the motor 43 drives the eccentric wheel 41 to rotate; during the rotation, the circumferential wall of the eccentric wheel 41 abuts against the abutting portion 42 of the cover plate 10, so that the distance between the abutting portion 42 and the rotating shaft of the eccentric wheel 41 gradually increases, and during the rotation, the eccentric wheel applies force to the cover plate 10, so that the cover plate 10 moves along the first direction. The direction of the force applied by the eccentric to the cover plate 10 is not exactly the same as the first direction, resulting in inconsistent movement of the cover plate 10 from side to side. The present application thus solves similar technical problems in the embodiment of the adjustment part 40 with the transmission of the eccentric wheel 41, thanks to the addition of the first stop 33.

The adjusting portion 40 may also be a mechanical transmission structure, as shown in fig. 4 and 5, the adjusting structure may include a sliding pin 46, a sliding slot 47 disposed on the cover plate 10 and angled to the first direction, and the sliding pin 46 may be inserted into the sliding slot 47 and slide in the sliding slot. The sliding pin 46 during sliding abuts against the wall of the sliding groove 47 so that the cover plate 10 can be moved in or against the first direction. During the movement along the first direction, the contact point of the sliding pin 46 with the wall of the sliding slot 47 changes all the time and is not always located on the center line of the cover plate 10, and the uneven force causes the degree of progress on both sides to be inconsistent. Therefore, the present application solves similar technical problems in the embodiment of the adjusting portion 40 having the structure of the slide pin 46 and the slide groove 47 due to the addition of the first stopper portion 33.

In a possible embodiment, the supporting portions 121 and 122, the rails 321 and 322, and the first stopping portion 33 each have at least two sets, and are symmetrically disposed on two sides of the drawer assembly 100. This arrangement, while adding slightly to the cost, is more stable in technical effect. As a simplified variant, the object of the utility model can also be achieved by providing the first stop 33 only on the track which reaches the upper end of the inclined extension 32 beforehand.

Further, the refrigeration appliance further comprises a bracket 30. As shown in fig. 3, the rails are provided on the bracket 30. The holder 30 is arranged fixedly on the refrigeration device, which is not shown in the figures. As a variant, the rail can also be formed on an inner wall of the refrigeration device, for example a convex or concave structure with an inclined surface or the like provided on the inner wall.

In a possible embodiment, the first blocking portion 33 is configured as an upwardly extending protrusion having a height greater than or equal to half the size of the support portions 121 and 122. In this way, the first blocking portion 33 is easily formed integrally with the rail, and the movement of the supporting portions 121 and 122 can be effectively prevented.

Fig. 4 and 5 show another embodiment of the present invention. Which differs from the embodiment shown in fig. 1 and 2 mainly in the adjustment part 40 and in the movement of the cover plate 10. The difference of the adjustment portion 40 can be referred to the foregoing. In the embodiment shown in fig. 1 and 2, the movement of the cover 10 in the first direction is driven by an electric transmission, and the adjustment portion 40 may be disposed near the front of the refrigeration appliance such that the cover 10 moves from front to back (first direction) to open the drawer, or the adjustment portion 40 may be disposed near the rear of the refrigeration appliance such that the cover 10 moves from back to front (first direction) to open the drawer. For aesthetic and space efficiency reasons, the adjustment portion 40 may be disposed close to the rear of the refrigeration appliance, i.e., in this case, the first direction is a rear-to-front direction. In the embodiment shown in fig. 4 and 5, the adjustment portion 40 can be manually adjusted and can be located close to the front of the refrigeration appliance, which is more convenient to operate, i.e. in this case the first direction is the forward-to-rearward direction.

Where fig. 4 and 5 are not described in detail, reference may be made to the description of fig. 1 and 2 of the present invention or to the description relating to the prior art, provided that it is clear that it does not conflict with the present embodiment.

While specific embodiments have been described above, these embodiments are not intended to limit the scope of the disclosure, even if only a single embodiment is described with respect to a particular feature. The characteristic examples provided in the present disclosure are intended to be illustrative, not limiting, unless differently stated. In particular implementations, the features of one or more dependent claims may be combined with those of the independent claims as technically feasible according to the actual requirements, and the features from the respective independent claims may be combined in any appropriate manner and not merely by the specific combinations enumerated in the claims.

The various embodiments described above and shown in the accompanying drawings are illustrative of the present application and are not intended to be exhaustive of the application. Any modification of the present application made by a person of ordinary skill in the related art within the scope of the basic technical idea of the present application is within the scope of the present application.
