Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerators, in particular to an electric push rod mounting structure and a refrigerator. BACKGROUND

[0002] With the improvement of people's living standards, the demand for refrigerators is also increasing. Modern automatic door opening refrigerators use the pushing force of the lower push rod assembly to overcome the self-locking force of the refrigerator door guide rail, so as to push the refrigerator door out. The lower push rod assembly is generally a single push rod structure and is directly installed at the bottom of the refrigerator, and is then fixed to the refrigerator base by screws from top to bottom.

[0003] However, the pushing force of the single push rod structure is insufficient, which may cause the refrigerator door to be unable to open automatically. At the same time, it is difficult to ensure that the structure is in the center of the refrigerator during assembly. When the refrigerator door needs to be opened, the force deviation may occur, causing the refrigerator door to shake and affecting the user experience. In addition, such an installation method requires the refrigerator to be placed horizontally for maintenance and replacement from the bottom, which is laborious. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide an electric push rod mounting structure and a refrigerator with sufficient pushing force, uniform force on the refrigerator door, and simple maintenance.

[0010] It can be understood that two sets of electric push rods are arranged, and the refrigerator door is automatically opened by the pushing force of the electric push rods through the telescopic rods on the electric push rods. The bottom of the refrigerator liner is correspondingly provided with two sink grooves, and the two sets of electric push rods are respectively installed in the corresponding sink grooves. The contact force point of the electric push rod and the refrigerator door changes from single to double, which improves the stability of the electric push rod structure, avoids the inclination of the refrigerator door due to uneven force, and the pushing force of the two sets of electric push rods is larger, thereby avoiding the situation that the refrigerator door cannot be opened due to small force. Meanwhile, the upper cover is arranged, which can close the electric push rod in the corresponding sink groove, not only ensuring the beauty of the refrigerator during use, but also directly opening the upper cover for maintenance and replacement, reducing the workload of after-sales maintenance, and further improving the user experience.

[0012] In one of the embodiments, the sink groove is further provided with a heat insulating piece, and the heat insulating piece is located above the electric push rod.

[0013] In one of the embodiments, the heat insulating piece is a half-shell shape and covers the electric push rod.

[0014] In one of the embodiments, the bottom side of the upper cover and the top surface of the heat insulating piece are fixedly attached to each other.

[0015] In one of the embodiments, a plurality of connecting columns are arranged in the sink groove, the electric push rod is fixed on the connecting column by a second fastener, and the disassembly direction of the second fastener is the up-down direction.

[0017] The application also provides the following technical solutions:

[0018] A refrigerator comprises a box body and a refrigerator door matched with each other, and the box body is provided with the electric push rod mounting structure in any of the above embodiments.

[0019] In one of the embodiments, the refrigerator door has a vertical longitudinal direction and an opposite transverse direction, the inner side of the refrigerator door is provided with a load-bearing convex strip extending in the transverse direction, and the end of the telescopic rod in the electric push rod abuts against the load-bearing convex strip.

[0020] In one of the embodiments, the refrigerator door is divided into two unit areas by the midpoint of the transverse direction, and each electric push rod corresponds to the middle part of each unit area.

[0021] Compared with the prior art, the application sets two sets of electric push rods, changes the contact force point of the electric push rod with the refrigerator door from single to double, increases the pushing force and improves the stability of the electric push rod mounting structure, avoids the situation that the refrigerator door cannot be opened due to small force and tilts due to uneven force; and the electric push rod is arranged in the corresponding sink of the refrigerator liner and is closed by the upper cover, which not only ensures the appearance of the refrigerator during use, but also can directly open the upper cover for maintenance and replacement, reduces the workload of after-sales maintenance and further improves the user experience.

[0035] Reference will now be made to Figures 1 to 3The application provides an electric push rod mounting structure 100 applied to a refrigerator 200 capable of automatically opening a door, mainly used for pushing the refrigerator door 202 to enable stable opening or closing, and through structural arrangement, the maintenance of the refrigerator 200 is more convenient, so as to improve the use experience of users.

[0036] As shown in Figures 1 to 5 The electric push rod mounting structure 100 comprises a refrigerator liner 10, electric push rods 20 and an upper cover 30, wherein the bottom of the refrigerator liner 10 is provided with two spaced-apart recesses 11; the electric push rods 20 are two sets, respectively installed in the corresponding recesses 11, and each electric push rod 20 has an extension rod 21 acting on the refrigerator door; and the upper cover 30 is installed on the top opening of the recess 11 to enclose the electric push rod 20 in the corresponding recess 11. It needs to be explained that the single push rod structure of the existing automatic door opening refrigerator 200 is insufficient in pushing force on the refrigerator door 202, and the single push rod needs to be arranged at the center position of the cabinet 201 to balance the pushing force on the refrigerator door 202, so that the refrigerator door 202 does not shake when it is opened due to force deviation, and the installation requirement is high; at the same time, the push rod is usually arranged at the bottom of the cabinet 201, and the refrigerator 200 needs to be placed upside down as a whole when it is maintained and replaced, which is troublesome. According to the application, two sets of electric push rods 20 are arranged, and two recesses 11 are arranged at the bottom of the refrigerator liner 10 in a spaced-apart manner, so that the two sets of electric push rods 20 are arranged in the corresponding recesses 11, thereby balancing the pushing force of the push rods on the refrigerator door 202, reducing the shaking of the refrigerator door 202 when it is opened, and increasing the use experience of users by changing the single push rod into two sets of electric push rods 20, so that the pushing force is also increased, thereby avoiding the situation that the refrigerator door 202 cannot be opened due to insufficient pushing force. At the same time, the electric push rod 20 is enclosed in the corresponding recess 11 by the upper cover 30, which does not affect the appearance during daily use, and when the electric push rod 20 structure at the bottom of the cabinet 201 needs to be maintained and replaced, the upper cover 30 can be directly opened for operation, without the need to place the refrigerator 200 upside down as a whole, which is convenient.

[0037] Here, the refrigerator 200 comprises a cabinet 201 and a refrigerator door 202 which cooperate with each other.

[0038] Preferably, the bottom surface of the recess 11 can be arc-shaped or quadrangular, etc., which is matched with the electric push rod 20 and other components installed therein. In this embodiment, the bottom surface of the recess 11 is quadrangular, so as to facilitate installation and after-sales maintenance.

[0039] Further, as shown in Figures 1 to 3 The recess 11 is further provided with a heat insulating piece 12 above the electric push rod 20.

[0040] As preferred, the heat insulation piece 12 is semi-shell-shaped and covers the electric push rod 20, can fill the blank position of the electric push rod 20 and the mounting groove, the heat insulation piece 12 can be foamed polystyrene or other materials with good heat preservation performance, can improve the heat preservation performance of the refrigerator 200, ensure that the temperature in the refrigerator 200 will not be lost from the bottom of the cabinet 201, and further improve the user experience.

[0041] For example, the sink 11 is also provided with a plurality of connecting columns 13 and second fasteners 14, the electric push rod 20 can be fixed on the connecting column 13 through the second fastener 14, which improves the stability of the electric push rod mounting structure 100, and the disassembly direction of the second fastener 14 is the up-down direction, as shown in Figure 3 , the direction from a to b is the up-down direction, which is convenient for disassembly and maintenance of the electric push rod 20, so as to reduce the workload of after-sales maintenance.

[0042] Here, the second fastener 14 can be a screw or the like, which is respectively installed into the corresponding connecting hole (not shown in the figure).

[0043] As shown in Figure 3 , the electric push rod 20 can be directly sleeved on the corresponding connecting column 13 through the adapter hole of the electric push rod 20 itself or through the limiting piece (the first fastener 31 and the second fastener 14 in the figure are limiting pieces) fixed to the electric push rod 20 itself and sleeved on the corresponding connecting column 13, and is fixed through the second fastener 14, so as to increase the firmness of the electric push rod 20 during fixing, prevent the electric push rod 20 from shaking due to loose fixing during action, and affect the user experience.

[0044] Please continue to refer to Figure 1 and Figure 2 , the bottom side of the upper cover 30 and the top surface of the heat insulation piece 12 are fixed to each other, so as to completely seal the electric push rod mounting structure 100 and improve the heat preservation of the cabinet 201.

[0045] Further, the upper cover 30 is two and is respectively buckled on the corresponding sink 11, the top area of the upper cover 30 and the corresponding sink 11 is fixed through the first fastener 31, and the disassembly direction of the first fastener 31 is the up-a down-b direction. In this way, the stability of the electric push rod mounting structure 100 can be increased, the shaking of the structure during action is further reduced, and the user experience is improved.

[0046] Here, the first fastener 31 can be a screw or the like, which is respectively installed into the corresponding connecting hole (not shown in the figure).

[0047] The application also provides a refrigerator 200, and the cabinet 201 of the refrigerator 200 is provided with the electric push rod mounting structure 100 in any of the above embodiments.
