Description

Technical Field

[0001] This utility model belongs to the technical field of automatic refrigerator door opening, and in particular relates to a refrigerator door opening component and a refrigerator. Background Technology

[0002] Existing refrigerators typically use a push rod motor to assist in opening the refrigerator door. During this process, the refrigerator door is only subjected to the pushing force of the push rod on the push rod motor, and not the pulling force of the push rod.

[0003] The refrigerator door is connected to the refrigerator body via guide rails. When the door opening angle is within the self-locking range of the guide rails, the door closes automatically thanks to the pull force of the guide rail's built-in retraction mechanism. Specifically, when the push rod of the push motor extends and the door opens a certain distance, the door automatically closes under the pull force of the guide rail springs in the retraction mechanism when the push rod retracts. However, when the push rod actually pushes the refrigerator door, due to assembly deviations and inertia, the door may disengage from the self-locking point of the retraction mechanism after opening. This prevents the guide rail from providing sufficient pull force, causing the door to fail to close automatically during subsequent retraction. Furthermore, at the end of the closing stroke, the retraction mechanism experiences significant resistance, which the guide rail springs cannot overcome, resulting in the door not closing completely during automatic closing. Utility Model Content

[0004] In view of this, it is necessary to provide a refrigerator door opening assembly and a refrigerator for solving the above-mentioned technical problems.

[0005] A refrigerator door opening assembly, comprising:

[0006] A push rod motor is used to be installed on the refrigerator body. The push rod motor includes a push rod, which can push the refrigerator door. The push rod is provided with a connector.

[0007] A mating component is used to install on the refrigerator door. The mating component can be connected with the connector to provide opposing forces between the push rod and the refrigerator door.

[0008] Understandably, the connection between the connector and the mating parts provides a pulling force between the push rod and the refrigerator door. This allows the following: First, when the push rod motor extends and pushes against the refrigerator door, the pulling force overcomes the inertia of the door opening, stopping both the door and the push rod simultaneously. This ensures the door opens within the self-locking range of the door's retraction mechanism, allowing the door to close automatically when the push rod retracts. Second, when the push rod motor retracts and the door closes automatically, the push rod exerts a pulling force on the door, ensuring it closes completely.

[0009] In one embodiment, the connector is disposed at one end of the push rod and screwed to the push rod.

[0010] Understandably, the connector is threaded to the push rod, which facilitates the assembly of the connector onto the push rod.

[0011] In one embodiment, the mating member and the connecting member are connected by magnetic attraction.

[0012] In one embodiment, the connector is configured as a magnetic push rod;

[0013] And, the mating component is configured as a magnet.

[0014] In one embodiment, the magnetic push rod is equipped with a shock absorber, and the push rod can push the refrigerator door through the shock absorber.

[0015] It is understandable that shock-absorbing components are used to cushion the impact of the push rod against the refrigerator door, thus preventing excessive noise when the push rod hits the refrigerator door.

[0016] In one embodiment, the mating member and the connecting member are connected by a snap-fit ​​mechanism.

[0017] In one embodiment, the connector includes a plurality of hooks, which are spaced apart along the circumferential direction of the connector.

[0018] And, the mating component is configured as a connecting sleeve.

[0019] In one embodiment, the connecting sleeve is enclosed to form an insertion interface, and a plurality of the hooks can pass through the insertion interface and engage with the connecting sleeve;

[0020] The diameter of the insertion interface gradually increases in the direction of the connector.

[0021] Understandably, the insertion interface of the connecting sleeve can be used to guide the engagement between the hook and the connecting sleeve, thus ensuring that the hook on the connector can engage with the connecting sleeve when the push rod pushes against the refrigerator door.

[0022] In one embodiment, the hook has a snap-fit ​​surface, and the hook can be stopped and abutted against the connecting sleeve through the snap-fit ​​surface;

[0023] The snap-fit ​​surface is beveled.

[0024] Understandably, the hook uses a beveled engagement surface to engage with the connecting sleeve, which facilitates the subsequent disengagement of the connecting sleeve and the hook, allowing the user to manually open the refrigerator door by pushing the lever a certain distance.

[0025] In addition, this application also provides a refrigerator, including a refrigerator body, a refrigerator door, and the refrigerator door opening assembly described above;

[0026] The push rod motor is mounted on the refrigerator body, and the mating part is mounted on the refrigerator door.

[0027] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0028] The refrigerator door opening assembly and refrigerator claimed in this application utilize the mating connection between the connector and the mating part to provide a pulling force between the push rod and the refrigerator door. This allows the following: Firstly, when the push rod motor controls the push rod to extend and push against the refrigerator door, the pulling force between the push rod and the refrigerator door overcomes the inertia of the refrigerator door when it is opened, causing the refrigerator door and the push rod to stop simultaneously. This ensures that the distance the refrigerator door is opened is within the self-locking range of the retraction mechanism on the refrigerator door, allowing the refrigerator door to automatically close when the push rod subsequently retracts. Secondly, when the push rod motor controls the push rod to retract and automatically close the refrigerator door, the push rod can generate a certain pulling force on the refrigerator door, ensuring that the refrigerator door can be completely closed.

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] It should be noted that when a component is said to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or may have an intervening component.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] like Figures 1 to 4As shown, the refrigerator door opening assembly 100 provided in this application includes a push rod motor 10 and a mating part 20. The push rod motor 10 is used to install on the refrigerator body (not shown). The push rod motor 10 includes a push rod 11, which can push the refrigerator door 200. A connecting part 30 is provided on the push rod 11. The mating part 20 is used to install on the refrigerator door 200 and can cooperate with the connecting part 30 to provide a counterforce between the push rod 11 and the refrigerator door 200. In other words, the refrigerator door opening assembly 100 of this application can provide a pulling force between the push rod 11 and the refrigerator door 200 by utilizing the cooperation between the connecting part 30 and the mating part 20.

[0039] As can be seen from the above, the refrigerator door opening assembly 100 of this application is applied in a refrigerator. When the push rod motor 10 controls the push rod 11 to extend and push the refrigerator door 200, the tension between the push rod 11 and the refrigerator door 200 can be used to overcome the inertia of the refrigerator door 200 when it is opened, so that the refrigerator door 200 and the push rod 11 stop at the same time. This ensures that the distance the refrigerator door 200 is opened is within the self-locking range of the retraction mechanism (not shown) on the refrigerator door 200, so that the refrigerator door 200 can automatically close when the push rod 11 retracts. On the other hand, when the push rod motor 10 controls the push rod 11 to retract and makes the refrigerator door 200 automatically close, the push rod 11 can generate a certain tension on the refrigerator door 200, which can ensure that the refrigerator door 200 can be completely closed.

[0040] like Figure 2 , Figure 4 As shown, in this application, the connector 30 is disposed at one end of the push rod 11 and screwed to the push rod 11, which facilitates the assembly of the connector 30 on the push rod 11. It is understood that those skilled in the art can also fix the connector 30 to the push rod 11 by means of tight fitting, welding, etc., which will not be elaborated here.

[0041] like Figure 1 , Figure 2 As shown, in the first embodiment of this application, the mating part 20 and the connecting part 30 are connected by magnetic attraction. That is, this embodiment can use magnetic attraction to provide tension between the push rod 11 and the refrigerator door 200.

[0042] like Figure 1 , Figure 2 As shown, in this embodiment, the connector 30 is configured as a magnetic push rod 310, which can be specifically configured as a metal part; and the mating part 20 is configured as a magnet 210, which can be specifically placed inside the refrigerator door 200.

[0043] like Figure 2As shown, in this embodiment, a shock absorber 311 is installed on the magnetic push rod 310, and the push rod 11 can push the refrigerator door 200 through the shock absorber 311. This allows the shock absorber 311 to buffer the push rod 11 when it pushes the refrigerator door 200, preventing excessive noise and thus reducing noise during the automatic opening of the refrigerator door 200. Here, the shock absorber 311 can be installed on the magnetic push rod 310 using a sleeve connection, and the material of the shock absorber 311 can be rubber, silicone, etc.

[0044] like Figure 3 , Figure 4 As shown, in the second embodiment of this application, the mating part 20 and the connecting part 30 are connected by a snap-fit ​​mechanism. That is, this embodiment can provide tension between the push rod 11 and the refrigerator door 200 through a mechanical connection.

[0045] like Figure 3 , Figure 4 As shown, in this embodiment, the connector 30 includes a plurality of hooks 320, which are spaced apart along the circumferential direction of the connector 30; and the mating part 20 is configured as a connecting sleeve 220, which can be connected to the refrigerator door 200 via a bracket 230, wherein the bracket 230 and the connecting sleeve 220 are integrally injection molded. Here, the number of hooks 320 is configured to be two, and the two hooks 320 are symmetrically arranged with respect to the center line of the connector 30. The two hooks 320 are set on the same mounting plate 330 and are integrally connected to the threaded connecting rod 340 through the mounting plate 330. The threaded connecting rod 340 can be inserted into the push rod 11 and threadedly connected to the push rod 11. During this process, the abutment between the mounting plate 330 and the push rod 11 can be used to limit the assembly between the threaded connecting rod 340 and the push rod 11.

[0046] like Figure 3As shown, in this embodiment, the connecting sleeve 220 forms an insertion interface 221, and multiple hooks 320 can pass through the insertion interface 221 and engage with the connecting sleeve 220. The diameter of the insertion interface 221 gradually increases towards the connector 30, so that during the process of the push rod 11 driving the hooks 320 to insert into the insertion interface 221 of the connecting sleeve 220, the insertion interface 221 of the connecting sleeve 220 can be used to guide the engagement between the hooks 320 and the connecting sleeve 220. This ensures that when the push rod 11 pushes against the refrigerator door 200, the hooks 320 on the connector 30 can engage with the connecting sleeve 220. Here, the connecting sleeve 220 protrudes outward and forms a guide portion 222. The guide portion 222 is correspondingly provided with the hook 320, and the hook 320 can be aligned with the corresponding guide portion 222 and inserted into the insertion interface 221 of the connecting sleeve 220 under the guidance of the guide portion 222. This facilitates the snap-fit ​​between the hook 320 and the connecting sleeve 220.

[0047] like Figure 3 , Figure 4 As shown, in this embodiment, the hook 320 has a snap-fit ​​surface 321, which is inclined, and the hook 320 can abut and limit the connection sleeve 220 through the snap-fit ​​surface 321. That is, the hook 320 can snap into the connection sleeve 220 using the inclined snap-fit ​​surface 321, which facilitates the subsequent disengagement of the connection sleeve 220 and the hook 320, allowing the user to manually open the refrigerator door 200, which has been opened a certain distance by the push rod 11. It should be noted that those skilled in the art can control the limiting force between the hook 320 and the connection sleeve 220 when they snap into each other by adjusting the tilt angle of the snap-fit ​​surface 321 on the hook 320; this will not be elaborated upon here.

[0048] In addition, this application also provides a refrigerator, including a refrigerator body, a refrigerator door 200, and the aforementioned refrigerator door opening assembly 100; a push rod motor 10 is mounted on the refrigerator body, and a mating part 20 is mounted on the refrigerator door 200. It is understood that the refrigerator door 200 of this application can be mounted on the refrigerator body in a rotating manner via a hinge, or the refrigerator door 200 can be mounted on the refrigerator body in a pull-out manner.

[0049] It should be noted that when the refrigerator door 200 of this application is automatically closed by the retraction mechanism on the hinge / guide rail connected to the refrigerator body, the retraction mechanism has a self-locking range. When the value corresponding to the opening angle / opening distance of the refrigerator door 200 falls within the value corresponding to the self-locking range of the retraction mechanism, the refrigerator door 200 can automatically close under the drive of the retraction mechanism when the push rod motor 10 controls the push rod 11 to retract. Otherwise, the refrigerator door 200 cannot close automatically and needs to be manually driven by the user.

[0050] In addition, the push rod motor 10 of this application can be programmed to automatically retract the push rod 11 after it extends and stops for a certain period of time. This solves the problem that if the user does not open the refrigerator door 200 further after the refrigerator door 200 has been automatically opened by the push rod 11 for a preset time, the refrigerator door 200 can automatically close, thus preventing the loss of cold air inside the refrigerator.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
