[0002] In order to prevent the cold air from leaking out, refrigerators usually use door seals to achieve a good sealing effect. This causes the door seals to have a large suction force, and a certain negative pressure will be formed in the refrigerator during refrigeration, so a large torque is required to open the door. Therefore, automatic door opening refrigerators are gradually becoming popular in the market. Automatic door opening of refrigerators mainly uses a movable push rod device to push the refrigerator door open. It is simple and practical, and is increasingly widely accepted.
[0003] However, due to the low temperature and high moisture content inside the refrigerator, the moisture will spread to the push rod device of the refrigerator after long-term use, reducing the service life of the push rod device. Utility Model Content

[0010] In the present solution, a shielding component is provided for the push rod device of the refrigerator, which can shield and protect the push rod of the refrigerator and reduce the negative impact of factors such as water vapor on the function of the push rod; transmission parts are provided for the two components respectively, so that the push rod and the shielding part can be set away from the power source, and its structural restrictions are smaller. The transmission parts can also change the action form of the power source to adapt to the movement requirements; both the push rod component and the shielding component can switch between the two states of pushing / retracting and retreating / shielding by moving, and by setting the coordination mode of the moving position of the push rod and the shielding part, the shielding part and the push rod can not interfere with each other during the movement; in addition, by driving the transmission parts of the two components through the same power source, the two parts can be controlled and linked synchronously at the same time, which not only reduces the occupied space and cost of the driving device, but also helps to achieve the effect of non-interference between the two components and good integrity.

This solution not only converts the movement of the transmission block into the movement of the push rod in the expected direction through the slide groove, but also indirectly adjusts the moving path and moving distance of the push rod by adjusting the shape of the slide groove and the drop distance at both ends, and reduces the limitation of the movement form of the transmission block on the movement form of the push rod.

[0066] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0067] Figure 1 This is a front perspective view of a refrigerator push rod device according to an embodiment of the utility model. Figure 1The refrigerator push rod device shown in the figure comprises a push rod assembly 10 and a shielding assembly 20, wherein: the push rod assembly 10 comprises a push rod 11 and a push rod transmission member, the push rod transmission member is used to drive the push rod 11 to move to the extended position or the retracted position, when the push rod 11 is in the extended position, the push rod 11 is used to cooperate with the push rod matching position on the door body of the refrigerator to open the door body; the shielding assembly 20 comprises a shielding part 21 and a shielding part transmission member, the shielding part 21 is used to shield the push rod matching position, and the shielding part 21 can move to a preset retreat position or shielding position. The utility model sets a shielding assembly 20 for the refrigerator push rod device, which can shield and protect the refrigerator push rod 11 and reduce the negative impact of factors such as water vapor on the function of the push rod 11. The transmission members are respectively set for the two components, so that the push rod 11 and the shielding part 21 can be set away from the power source, and the structural restrictions are smaller. The transmission member can also change the action form of the power source to adapt to the movement requirements.
[0068] When the shielding part 21 of the utility model is in the retracted position, the push rod 11 can move to the extended position; when the push rod 11 is in the retracted position, the shielding part 21 can move to the shielding position. Both the push rod assembly 10 and the shielding assembly 20 can switch between the two states of door pushing / retracting and retracting / shielding by moving, and by setting the cooperation mode of the moving position of the push rod 11 and the shielding part 21, the shielding part 21 and the push rod 11 can not interfere with each other during the movement. In the utility model, this cooperation mode between the two components is achieved by driving with the same power source.
[0069] By driving with the same power source, the two components can be controlled and linked synchronously at the same time, which not only reduces the space occupied and cost of the drive device, but also helps to achieve the effect of non-interference between the two components and good integrity.
[0070] Figure 2 This is a back perspective view of a refrigerator push rod device according to an embodiment of the utility model. Figure 1 , Figure 2 As shown, the push rod transmission member includes a first rotating wheel 12, and the first rotating wheel 12 serves as the input end of the push rod transmission member; the shielding part transmission member includes a second rotating wheel 22, and the second rotating wheel 22 serves as the input end of the shielding part transmission member; the power source drives the rotating shafts of the first rotating wheel 12 and the second rotating wheel 22 to rotate respectively, so as to drive the push rod 11 and the shielding part 21 to move at the same time. By arranging rotating wheels in the two transmission members respectively, and making the power source drive the rotating shafts of the two rotating wheels at the same time, a specific scheme of driving the two transmission members at the same time with one power source is provided. Among them, the selection of the rotating wheels is conducive to transmitting and converting the motion form of the power source. For example, the rotating shafts of the two rotating wheels can be coaxially fixed and rotated at the same speed, or the transmission effect can be adjusted by adjusting the rotating radius of the rotating wheels, the connection position of the rotating shafts, etc.
[0071] In this embodiment, the two wheels are driven by the same power source, that is, the power source is connected to the shafts of the two wheels respectively. In actual implementation, the two shafts can be the same shaft to make the overall device structure more compact and occupy less space.
[0072] In this embodiment, the push rod transmission member includes a transmission block 13, such as Figure 4 As shown, the transmission block 13 is used as the output end of the push rod transmission member, and is used to move and drive the push rod 11 to move between the extended position and the retracted position along the first direction. Specifically, the vertical direction shown in the figure is the first direction referred to in this article. The transmission block 13 includes a slide groove 14, and the push rod 11 is slidably inserted in the slide groove 14. The two ends of the slide groove 14 form a drop in the first direction, so that when the push rod 11 slides along the slide groove 14, it can generate displacement in the first direction. In this embodiment, the transmission block 13 with the slide groove 14 is used as the output end of the push rod transmission member, and the push rod 11 is inserted in the slide groove 14, so that when the transmission block 13 moves, the push rod 11 is driven to move by the pushing action of the wall of the slide groove 14; in addition, the two ends of the slide groove 14 are set with a drop in the first direction, so that when the push rod 11 slides back and forth in the slide groove 14, it can generate displacement in the first direction, that is, it moves back and forth between the extended position and the retracted position to switch the working state of the push rod 11. This solution not only converts the movement of the transmission block 13 into the movement of the push rod 11 in the expected direction through the slide groove 14, but also indirectly adjusts the moving path and moving distance of the push rod 11 by adjusting the shape of the slide groove 14 and the drop distance at both ends, and reduces the limitation of the movement form of the transmission block 13 on the movement form of the push rod 11.
[0073] Figure 5The schematic diagram of the structure near the push rod 11 of the refrigerator push rod device of one embodiment of the utility model. The push rod 11 in this embodiment includes a rod body 111 and a bending portion 112, the rod body 111 is arranged parallel to the first direction, the bending portion 112 is perpendicular to the first direction and fixed to the rod body 111, and the bending portion 112 is vertically inserted in the slide groove 14. The push rod 11 is arranged as a fixedly connected rod body 111 and a bending portion 112 to define different functions of the two parts, wherein the bending portion 112 is used to cooperate with the slide groove 14 and drive the rod body 111 to move, and the rod body 111 is used as the door-pushing part of the push rod assembly 10. In addition, the rod body 111 is arranged parallel to the first direction, and the bending portion 112 is arranged perpendicular to the first direction and vertically inserted in the slide groove 14, so that when the push rod 11 moves along the first direction, it can move along the rod length of the rod body 111, and the end of the rod body 111 is used to push the door. The push rod transmission member includes a first limit member 15, which is fixed and includes a first limit channel, which is arranged along a first direction, and the rod 111 is arranged in the first limit channel and can slide axially. In addition, the present solution sets a limit structure for the rod 111 to limit the movement of the rod 111 in directions other than the first direction, thereby avoiding the influence of the movement direction of the transmission member or the shape of the slide groove 14 on the movement direction of the rod 111. On this basis, the limitations of the arrangement form of the aforementioned transmission member and the slide groove 14 are reduced.
[0074] The push rod 11 structure selected in this embodiment is a preferred example adapted to the above-mentioned slide groove 14 and transmission block 13 structure. During the actual implementation process, the specific structure and orientation of the push rod 11 can be adjusted as needed without affecting the sliding effect of the push rod 11 in the slide groove 14.
[0075] like Figure 4 As shown, the push rod transmission also includes a first connecting rod 16, a second connecting rod 17 and a second limiting member 18, wherein: one end of the first connecting rod 16 is connected to the first rotating wheel 12 and offset from its rotation center, and the other end is connected to the second connecting rod 17 and is used to drive the second connecting rod 17 to move; the second limiting member 18 is fixed and includes a second limiting channel, the second limiting channel is arranged along a second direction perpendicular to the first direction, and the second connecting rod 17 can be slidably penetrated into the second limiting channel; the second connecting rod 17 is used to drive the transmission block 13 to move along the second direction. In the embodiment, a second connecting rod 17 offset from the center of the first rotating wheel 12 is provided to transmit the movement of the first rotating wheel 12, so as to convert its rotation into other desired forms of movement; the first connecting rod 16 is connected between the second connecting rod 17 and the transmission block 13 to drive the transmission block 13 to move, and a second limiting member 18 is provided to limit the rotation of the second connecting rod 17 relative to the first connecting rod 16 and limit the movement of the second connecting rod 17 along the rod length direction; the second limiting channel is provided along the second direction to further limit the movement of the second connecting rod 17 along the rod length in the second direction, thereby indirectly limiting the movement of the transmission block 13 along the second direction.
[0076] The first connecting rod 16, the second connecting rod 17 and the second limit member 18 are preferred transmission structures of the utility model, which are only used as examples. On the basis of achieving the effect of moving the transmission block 13 along the second direction, those skilled in the art can appropriately adjust the structure and number of the several limit members arranged between the first rotating wheel 12 and the transmission block 13.
[0077] Depend on Figure 1 It can be seen that, taking the above-mentioned push rod transmission member adopted in this embodiment as an example, when the first rotating wheel 12 rotates counterclockwise from 0-180 degrees, as the angle increases, the first connecting rod 16 can drive the second connecting rod 17 to move rightward to the maximum distance, thereby further pushing the push rod 11 to move to the leftmost end of the slide slot 14, and move to the extended position along the first direction, at which time the first limiter 15 limits the moving direction of the push rod 11. Accordingly, it can be seen from the above-mentioned scheme that the first rotating wheel 12 and the second rotating wheel 22 are driven by the same power source and realize synchronous linkage control that in this embodiment, when the first rotating wheel 12 rotates in the above-mentioned direction, the second rotating wheel 22 simultaneously rotates counterclockwise from 0-180 degrees and drives the corresponding shielding part transmission member to move.
[0078] In addition, for the shielding assembly 20 in this embodiment, the shielding part transmission member includes a connecting rod group, which is the output end of the shielding part transmission member, connected between the shielding part 21 and the second rotating wheel 22, and is used to drive the shielding part 21 to move to the shielding position or the retracted position. This embodiment uses a connecting rod group as the transmission member of the shielding part 21, which can realize the setting of the shielding part 21 away from the second rotating wheel 22. Its structural restrictions are smaller, avoiding interference between the above two components. In the actual implementation process, a transmission member other than the connecting rod group can be used; in addition, the use of a transmission member can also transform the action form of the power source to adapt to the movement requirements.
[0079] like Figure 3 As shown, the connecting rod group includes a third connecting rod 23, a fourth connecting rod 24 and a third limiting member 25. The connecting rod group is set as two connecting rods, which takes up little space and is convenient for adjusting the movement form. Among them, the third connecting rod 23 is used as the input end of the connecting rod group to drive the fourth connecting rod 24 to move; the third limiting member 25 acts on the fourth connecting rod 24 to limit the rotation of the fourth connecting rod 24 relative to the third connecting rod 23, and makes the fourth connecting rod 24 move linearly along its extension direction, which indirectly limits the movement form of the shielding part 21, and in the actual implementation process, the movement direction can be adjusted by replacing the third limiting member 25 as needed, which has good adaptability.
[0080] In this embodiment, the third limiting member 25 includes two limiting plates arranged opposite to each other, the two limiting plates are used to enclose a limiting channel, the fourth connecting rod 24 is passed through the limiting channel, and the two limiting plates are respectively located on the upper and lower sides of the fourth connecting rod 24 along the thickness direction, which is adapted to the structural characteristics of the connecting rod. The limiting structure is simple and easy to adjust.
[0081] In this embodiment, the shielding part transmission member also includes a fourth limit member 26, and the fourth limit member 26 includes a fixed hinged portion to limit the movement of the third link 23 to swinging. The hinged portion is hinged to the third link 23 and is away from the fourth link 24. The hinged portion can be fixed to the external refrigerator shell to make the movement of the entire link group more stable and the installation is more convenient. The third link 23 can swing around the hinged portion.
[0082] like Figure 6 As shown, in this embodiment, the shielding part transmission member also includes a third rotating wheel 27, the third rotating wheel 27 is connected to the third connecting rod 23, and abuts against the rim of the third rotating wheel 27, the third rotating wheel 27 pushes the third rotating wheel 27 to move, to convert the rotational movement of the second rotating wheel 22 into a push on the third connecting rod 23 through the abutment of the rim, thereby driving the third connecting rod 23 to swing, which adapts to the effect of the third connecting rod 23 swinging around the fourth limit member 26 in the aforementioned scheme.
[0083] Depend on Figure 3 It can be seen that, taking the above-mentioned shielding part transmission member adopted in this embodiment as an example, when the second rotating wheel 22 rotates counterclockwise from 0-180 degrees, the third connecting rod 23 swings to the left to the maximum amplitude, and the second rotating wheel 22 drives the third rotating wheel 27 to rotate, and further drives the third connecting rod 23 to swing to the left, wherein the third rotating wheel 27 transmits power and reduces friction. When the third connecting rod 23 swings to the left, it drives the fourth connecting rod 24 to move to the left, and the third limiting member 25 limits the movement direction of the fourth connecting rod 24. Further, the fourth connecting rod 24 drives the shielding part 21 to move to the left to the maximum displacement.
[0084] Here, this paper combines Figure 1 The following two methods are used as references for implementing or adjusting the present embodiment only.
[0085] ① Move in the opposite direction of the above transmission parts, that is, the first connecting shaft is reversed, and the first rotating wheel 12 and the second rotating wheel 22 are rotated clockwise to the original 0 degree position. Further, the transmission block 13 moves to the leftmost side, and the push rod 11 is located at the rightmost end of the slide slot 14. At this time, the push rod 11 and the shielding part 21 are reset;
[0086] ② Continue to move in the same direction as the above transmission parts, that is, the first rotating wheel 12 and the second rotating wheel 22 rotate counterclockwise from 180-360 degrees, that is, rotate the second half of a circle, and the same reset effect as in ① can also be achieved.
