Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. 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.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present application. Fig. 2 is a schematic structural view of the refrigerator shown in fig. 1 in a state that a door is opened.

The embodiment of the application provides a refrigerator. The refrigerator may include a cabinet 100 and a drawer 200.

The cabinet 100 may have a refrigerating compartment 11 and a first opening 12 communicating with the refrigerating compartment 11. Further, the user can store and take food and the like into and out of the cooling compartment 11 through the first opening 12, and can refrigerate and keep the food fresh through the cooling compartment 11. The drawer 200 includes a drawer body 21 and a door 22 connected to the drawer body 21. The drawer body 21 is used for containing food, and at least part of the drawer body 21 is movably arranged in the refrigerating compartment 11, so that a user can conveniently store and take the food in the refrigerating compartment 11 through the drawer body 21. The door 22 can close the first opening 12 to improve the refrigerating and refreshing effects in the refrigerating compartment 11. The door 22 can move in a first direction to open the first opening 12 and drive the drawer body 21 to move out of the refrigerating compartment 11. Furthermore, the user can conveniently pull the drawer 200 by pulling the door 22 in the first direction to move the drawer body 21 at least partially out of the refrigerating compartment 11, so that the user can access food to the drawer body 21. Or, the user pushes the door body 22 in the second direction to make the door body 22 close the first opening 12, and the door body 12 also pushes the drawer body 21 into the refrigerating compartment 11, so as to store the food in the drawer body 21 in the refrigerating compartment 11 for refrigeration and preservation.

It can be understood that when the drawer 200 is located at the bottom of the refrigerator, the user bends over to pull the door 22, so that it is inconvenient to open the door 22 manually, especially for some elderly people, and it is difficult to bend over to exert force. On the other hand, in some refrigerators, in order to ensure the refrigerating effect of the refrigerating compartment 11, the box 100 and the door 22 are sealed by a strong suction method, so that it is more inconvenient for a user to manually open the drawer 200. Therefore, the refrigerator may further include an automatic door opener, and the refrigerator may automatically complete the opening of the drawer 200 by the door opener.

Referring to fig. 3, fig. 3 is a schematic structural view of the refrigerator shown in fig. 1 with the box and the driving mechanism removed. The automatic door opening apparatus may include a push rod 300 and a driving mechanism 400.

As shown in fig. 3, the push rod 300 is provided on the drawer 200, and as shown in fig. 4, the driving mechanism 400 is provided on a side wall of the cabinet 100 forming the refrigerating compartment 11. The driving mechanism 400 can drive the push rod 300 to move in a first direction, so that the refrigerator automatically completes the action of opening the drawer 200.

In some embodiments, the push rod 300 is fixedly connected only to the drawer body 21. For example, the drawer body 21 includes a first bottom wall 211 and a first annular wall 212 disposed around the first bottom wall 211 to form a storage cavity 213, and the push rod 300 is fixed to the first bottom wall 211 or the first annular wall 212. Therefore, when the push rod 300 pushes the drawer 200, the acting force of the push rod 300 acts on the first bottom wall 211 or the first annular wall 212 corresponding to the drawer body 21, and then is transmitted to the door 22 through the drawer body 21, so that the door 22 moves along the first direction.

It will be appreciated that, in practice, to increase the volume of the storage compartment 213, both the first bottom wall 211 and the first circumferential wall 212 of the drawer body 21 are thinner, resulting in lower structural strength of the first bottom wall 211 and the first circumferential wall 212. When the driving mechanism 400 applies a force to the push rod 300 to drive the push rod 300 to move, the force applied to the push rod 300 is transmitted to the corresponding first bottom wall 211 or the first annular wall 212 of the drawer body 21, so that the corresponding first bottom wall 211 or the corresponding first annular wall 212 is deformed. On the other hand, when the first bottom wall 211 or the first annular wall 212 is deformed, the matching between the drawer body 21 and the box 100 may be affected, and thus the drawer body 21 and the box 100 interfere with each other and the drawer body 21 cannot be taken out from the refrigeration compartment 11. On the other hand, the deformation of the first bottom wall 211 or the first annular wall 212 may even cause irreversible damage to the drawer body 21. In addition, the acting force generated by the driving mechanism 400 will firstly deform the first bottom wall 211 or the first annular wall 212 and then drive the drawer 200 to move integrally, so that the efficiency of the driving mechanism 400 to implement the automatic door opening operation is low.

As shown in fig. 3, in order to reduce or even avoid the influence of the deformation of the drawer body 21 caused by the push rod 300 being disposed on the drawer body 21, the push rod 300 may be connected to the drawer body 21, and one end of the push rod 300 close to the door 22 along the first direction abuts against the door 22. Therefore, the acting force of the driving mechanism 400 on the push rod 300 can be directly applied to the door 22 on the one hand to push the door 22 to open the first opening 12.

On the other hand, the push rod 300 can be regarded as a reinforcing rib connected between the door 22 and the drawer body 21, and further, the push rod 300 can improve the strength of the whole drawer 200, so that the drawer 200 is not easily deformed by the acting force of the driving mechanism 400.

Referring to fig. 4, fig. 4 is a schematic structural view of the refrigerator shown in fig. 1 from another perspective after the refrigerator body and the driving mechanism are removed. In order to make the acting force applied by the push rod 300 to all the positions of the door body 22 more uniform, one end of the push rod 300 close to the door body 22 along the first direction is provided with a push plate 31, and the push plate 31 is attached to the door body 22. Furthermore, by increasing the contact area between the push rod 300 and the door 22, the door 22 can be stressed more uniformly and is not easily damaged.

In actual use, as shown in fig. 2, the storage chamber 213 formed by the drawer body 21 is opened upward. In order to make the overall appearance of the refrigerator more beautiful, the push rod 300 is disposed on a side of the first bottom wall 211 facing away from the storage cavity 213, i.e., as shown in fig. 3 and 4, the push rod 300 is disposed at the bottom of the first bottom wall 211. Therefore, when the drawer body 21 moves to the outside of the refrigerating compartment 11, the push rod 300 can be shielded by the drawer body 21, so as to prevent the push rod 300 from being exposed to affect the aesthetic feeling of the whole refrigerator.

As shown in fig. 3, the first annular wall 212 includes a first side wall 2121 facing the door 22, and a first air duct 23 is provided between the first side wall 2121 and the door 22. The end of the first side wall 2121 away from the first bottom wall 211 is connected to the door 22, that is, the upper end edge of the first side wall 2121 is connected to the door 22.

It can be understood that, compared with the door 22 completely attached to the first side wall 2121, the first air duct 23 can increase the contact area of the cold air in the drawer body 21 and the refrigeration compartment 11, so as to improve the refrigeration effect of the refrigerator on the food stored in the drawer body 21. Further, as shown in fig. 4, the first side wall 2121 may be provided with a first through hole 2123, and the first through hole 2123 communicates the storage cavity 213 and the first air duct 23, so that cold air in the first air duct 23 can directly exchange heat with the inside of the storage cavity 213, and the refrigeration effect of the refrigerator on food in the storage cavity 213 is further improved.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a box body and a driving mechanism of the refrigerator shown in fig. 1.

As shown in fig. 4, the first annular wall 212 may further include a second side wall 2122 connected to the first side wall 2121, the second side wall 2122 being provided with the slider 24. As shown in fig. 5, the side wall of the cabinet 100 forming the cooling compartment 11 is provided with a guide rail 13. As shown in fig. 2, the guide rail 13 is slidably connected to the sliding member 24 so as to be moved to the outside of the refrigerating compartment 11 or to the inside of the refrigerating compartment 11 through the drawer body 21.

It can also be understood here that when only the upper end edge of the first side wall 2121 is connected to the door 22 and the push rod 300 is disposed on the first bottom wall 211, if the push rod 300 is connected to the first bottom wall 211 and does not abut against the door 22, when the driving mechanism 400 drives the push rod 300, the push rod 300 pushes the drawer body 21, which easily causes the drawer body 21 to rotate downward relative to the door 22 with the upper end edge of the first side wall 2121 as a fulcrum, so that the drawer 200 is completely deformed as a whole. At this time, the sliding member 24 of the drawer body 21 is partially tilted with respect to the rail 13 of the casing 100, and the movement of the drawer body 21 is affected.

Referring to fig. 6, fig. 6 is a schematic structural diagram of a driving mechanism of the refrigerator shown in fig. 1. The drive mechanism 400 may include a drive member 41 and a transmission member 42. The driving member 41 is used for providing power, and the driving member 41 can be in transmission connection with the push rod 300 through the transmission member 42. Further, the push rod 300 is driven by the driving part 41 to move in the first direction to complete the operation of automatically opening the drawer 200 of the refrigerator.

As shown in fig. 5, in order to avoid that the driving mechanism 400 occupies more space of the refrigerating compartment 11, which leads to a reduction in the amount of food that can be stored in the refrigerating compartment 11, the driving mechanism 400 may be only partially disposed in the refrigerating compartment 11.

Illustratively, the transmission member 42 may be partially located in the refrigerating compartment 11 to enable the transmission member 42 to be in transmission connection with the push rod 300. The driving part 41 may be embedded in a side wall forming the refrigerating compartment 11 or be located entirely outside the refrigerating compartment 11, which is not limited in the embodiment of the present application.

Taking the refrigerator as an example in which the side wall forming the refrigerating compartment 11 may include a foamed layer, the driving part 41 may be embedded in the foamed layer. It is understood that the foam layer is a layered structure supported by the foam material and having the functions of heat preservation and buffering, for example, the foam layer is made of foam material. On the other hand, the foaming layer also has a good noise reduction effect, so that noise generated when the driving part 41 operates can be reduced.

The embodiment of the present application does not limit the specific transmission structure of the transmission component 42 and the push rod 300. For example, the transmission member 42 may be a push block driven by the driving member 41 to move linearly to push the push rod 300 to move in the first direction. Alternatively, as shown in fig. 6, the transmission member 42 may further include a sheet tooth, and as shown in fig. 3 and 4, an end of the push rod 300 away from the door 22 includes a tooth portion 32 engaged with the sheet tooth, so that the transmission member 42 may drive the push rod 300 to move in the first direction through a gear transmission manner.

In some embodiments, the refrigerator further includes a sensor (not shown) and a controller (not shown). The sensor is disposed on the door 22 and is configured to detect a vibration signal of the door 22. The controller is electrically connected to the sensor, and the controller is configured to control the driving mechanism 400 to drive the push rod 300 according to the vibration signal detected by the sensor.

Therefore, in the course of actual use, when the user kicks the door 22 with a foot or the like, the door 22 vibrates. At this time, the sensor can detect a vibration signal generated by the door 22 and communicate with the controller, the controller controls the driving mechanism 400 according to the vibration signal detected by the sensor, and finally the driving mechanism 400 drives the push rod 300 to move along the first direction, so as to complete the action of automatically opening the drawer 200 of the refrigerator.

Therefore, when the drawer 200 is located at the bottom of the refrigerator, the user can trigger the action of automatically opening the drawer 200 of the refrigerator by directly kicking the door 22 with the feet. Therefore, the refrigerator in the embodiment of the application has the advantage of convenience in use.

In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.

The refrigerator provided by the embodiment of the present application is described in detail above, and the principle and the implementation of the present application are explained by applying specific examples herein, and the description of the above embodiment is only used to help understanding the method and the core idea of the present application; meanwhile, for those skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
