Description

Technical Field

[0001] The utility model belongs to the technical field related to refrigerators, and particularly relates to a depth adjustment mechanism and a refrigerator. Background Art

[0002] In order to facilitate the stable placement of the refrigerator in the user's home, the bottom of the refrigerator uses an adjustment foot mechanism to achieve the leveling of the refrigerator to stability. In addition, in order to facilitate the movement of the refrigerator during installation, the movement is mainly achieved by the rollers of the compressor base plate assembly at the bottom of the refrigerator. When the installer pushes the refrigerator to the specified position, the adjustment feet at the bottom of the refrigerator will be adjusted to level the refrigerator, so that the refrigerator remains stable and is not easy to shake or move after the adjustment feet are flush with the ground.

[0003] The current refrigerator products on the market do not consider the problem of depth adjustment, especially when the depth of the built-in refrigerator is less than the depth of the user's cabinet. During installation, the exterior surface of the refrigerator door is ensured to be flush with the cabinet. The refrigerator is only adjusted by the grip of the feet to reduce the backward movement of the refrigerator. There is no design measure to completely solve this problem. After the refrigerator is installed, when the user is using it, if he pushes the refrigerator unconsciously, the refrigerator will still move backward, especially some high-end refrigerators with automatic pressing function. When pressing to open the door, the refrigerator will be pushed backward. At the same time, when focusing on the installation of built-in refrigerators, when the user's cabinet depth (the depth of the market cabinet is usually 600mm) is greater than the depth of the built-in refrigerator (such as the current second-generation refrigerator The depth is 585mm), if there is a press or push to move the refrigerator backward, it will cause the built-in refrigerator to move backward to the inside of the cabinet, which is significantly lower than the cabinet, destroying the overall aesthetics of the built-in cabinet in the user's home. Utility Model Content

[0004] In view of this, it is necessary to provide a depth adjustment mechanism and a refrigerator for solving the above technical problems.

[0005] A depth adjustment mechanism, the depth adjustment mechanism comprising:

[0006] A fixing block, used for fixing and connecting to the refrigerator body;

[0007] A telescopic driving member, used to be connected to the refrigerator body and independently arranged relative to the fixed block, the telescopic driving member comprising a telescopic rod;

[0008] A connecting rod assembly is hinged to the fixed block and the telescopic rod respectively, the connecting rod assembly includes a limiting portion, and the connecting rod assembly can be deformed under the driving of the telescopic rod to drive the limiting portion to extend out of the refrigerator body;

[0009] A controller is electrically connected to the telescopic driving member and is used to control the operation of the telescopic driving member.

[0010] It can be understood that by controlling the operation of the telescopic drive member through the controller, the limiting portion of the connecting rod assembly extending out of the refrigerator body is controlled, and then the abutment between the limiting portion and the wall is utilized to limit the embedding depth of the refrigerator when it is embedded in the cabinet. This is not only easy to operate, but also ensures that the outer surface of the refrigerator door of the refrigerator body is flush with the cabinet, thereby improving the aesthetics of the refrigerator when it is embedded in the cabinet.

[0011] In one embodiment, the connecting rod assembly includes a first connecting rod and a second connecting rod, the first connecting rod is hinged to the telescopic rod, and the second connecting rod is hinged to the fixed block;

[0012] The first connecting rod is hinged to the second connecting rod, and the position where the first connecting rod and the second connecting rod are hinged is formed as the limiting portion.

This simplifies the structure of the connecting rod assembly while satisfying the requirement that the deformation of the connecting rod assembly can enable the limiting portion to extend out of the refrigerator body.

[0014] In one embodiment, the connecting rod assembly further includes a third connecting rod, one end of the third connecting rod is fixedly connected to the telescopic rod, and the other end of the third connecting rod is hinged to the first connecting rod.

[0015] In one embodiment, a connecting plate is provided on the fixing block, and an end of the second connecting rod away from the first connecting rod is rotatably mounted on the connecting plate, so that the second connecting rod is hinged to the fixing block;

[0016] Wherein, the connecting plate is in a right-angle shape.

[0017] In one embodiment, the movement direction of the telescopic rod is perpendicular to the length direction of the fixed block.

[0018] In one embodiment, the controller includes a trigger member, and the trigger member can be triggered multiple times, and each time the trigger member is triggered, the movement stroke of the telescopic rod when it is extended is controlled to be consistent.

[0019] It can be understood that, through the above-mentioned structural setting, the user can control the distance when the upper limit part of the connecting component extends out of the refrigerator body by triggering the trigger member multiple times. In this way, when the depth adjustment mechanism is used in the refrigerator, the different embedding depths of the refrigerator in the cabinet can be limited.

[0020] In one embodiment, the depth adjustment mechanism further includes a fixed base, and the fixed base is used to be fixedly connected to the refrigerator body;

[0021] Wherein, the telescopic driving member is installed on the fixed base.

[0022] In one embodiment, the telescopic drive member is configured as a push rod motor.

[0024] The present application also seeks protection for a refrigerator, comprising a refrigerator body and the depth adjustment mechanism described above, wherein the depth adjustment mechanism is installed on the refrigerator body.

[0025] In one embodiment, the number of the depth adjustment mechanisms is configured as two sets, and the two sets of the depth adjustment mechanisms are arranged at intervals along the width direction of the refrigerator body.

[0026] It can be understood that two sets of depth adjustment mechanisms are used together to adjust the embedding depth of the refrigerator in the cabinet, which can improve the stability of the refrigerator when the embedding depth in the cabinet is fixed.

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

[0028] The depth adjustment mechanism and refrigerator for which protection is sought in the present application realize control of the limiting portion of the connecting rod assembly extending out of the refrigerator body by controlling the operation of the telescopic drive member through a controller, and then utilizes the abutment between the limiting portion and the wall to limit the embedding depth of the refrigerator when it is embedded in the cabinet. This is not only easy to operate, but also ensures that the outer surface of the refrigerator door of the refrigerator body is flush with the cabinet, thereby improving the aesthetics of the refrigerator when it is embedded in the cabinet.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] like Figure 1 , Figure 3 As shown, the depth adjustment mechanism 100 claimed in the present application is mounted on the refrigerator body 200, and is used to limit the embedding depth of the refrigerator body 200 when embedded in the cabinet. Of course, in other embodiments, the depth adjustment mechanism 100 can also be mounted on equipment that requires embedded installation, such as washing machines and ovens, which will not be elaborated here.

[0039] like Figures 1 to 4As shown, the depth adjustment mechanism 100 provided in one embodiment of the present application includes a fixed block 10, a telescopic driving member 20, a connecting rod assembly 30 and a controller (not shown), wherein the fixed block 10 is used to be fixedly connected to the refrigerator body 200; the telescopic driving member 20 is used to be connected to the refrigerator body 200 and is independently arranged relative to the fixed block 10, and the telescopic driving member 20 includes a telescopic rod 21; the connecting rod assembly 30 is respectively hinged to the fixed block 10 and the telescopic rod 21, and the connecting rod assembly 30 includes a limiting portion 301, and the connecting rod assembly 30 can be deformed under the drive of the telescopic rod 21 to drive the limiting portion 301 to extend out of the refrigerator body 200; the controller is electrically connected to the telescopic driving member 20, and is used to control the operation of the telescopic driving member 20. That is, when the depth adjustment mechanism 100 is assembled on the refrigerator body 200 and works, the telescopic driving member 20 can be controlled by the controller to work, so as to control the limiting portion 301 to extend out of the refrigerator body 200, and to limit the embedded depth of the refrigerator when it is embedded in the cabinet. Here, the fixing block 10 is configured as a sheet metal, and can be fixed to the refrigerator body 200 by using fasteners such as screws.

[0040] It can be understood that when the depth adjustment mechanism 100 of the present application is assembled on the refrigerator body 200, the controller can be used to control the operation of the telescopic drive member 20 to achieve control of the limiting portion 301 on the connecting rod assembly 30 that extends out of the refrigerator body 200, and then the abutment between the limiting portion 301 and the wall is used to limit the embedding depth of the refrigerator 1000 when it is embedded in the cabinet. This is not only easy to operate, but also ensures that the appearance surface of the refrigerator door (not shown) of the refrigerator body 200 is flush with the cabinet, thereby improving the aesthetics of the refrigerator 1000 when it is embedded in the cabinet.

[0041] like Figure 2 , Figure 4 As shown, the telescopic drive member 20 is configured as a push rod motor 210, so that the telescopic drive member 20 can be made of local materials, which has the effect of reducing costs. Of course, in other embodiments, the telescopic drive member 20 can also be configured as a telescopic cylinder, a telescopic motor, or a motor and a lead screw nut assembly, which will not be elaborated here.

[0042] As preferably, Figure 2 , Figure 4 As shown, the depth adjustment mechanism 100 further includes a fixed base 211, which is used to be fixedly connected to the refrigerator body 200; wherein the telescopic drive member 20 is installed on the fixed base 211. In other words, the fixed base 211 is used to carry the telescopic drive member 20. It should be noted that the shape of the fixed base 211 can be specifically set according to the use requirements of carrying the telescopic drive member 20, which will not be elaborated here.

[0043] like Figure 2 , Figure 4As shown, the connecting rod assembly 30 includes a first connecting rod 31 and a second connecting rod 32, wherein the first connecting rod 31 is hinged to the telescopic rod 21, and the second connecting rod 32 is hinged to the fixed block 10; wherein the first connecting rod 31 is hinged to the second connecting rod 32, and the hinged portion of the first connecting rod 31 and the second connecting rod 32 is formed as a limiter 301, so that the deformation of the connecting rod assembly 30 can realize the limiter 301 extending out of the refrigerator body 200, thereby simplifying the structure of the connecting rod assembly 30. Of course, in other embodiments, the connecting rod assembly 30 can also be configured as a four-link structure. Here, the movement direction of the telescopic rod 21 is perpendicular to the length direction of the fixed block 10.

[0044] like Figure 2 , Figure 4 As shown, the connecting rod assembly 30 also includes a third connecting rod 33, one end of the third connecting rod 33 is fixedly connected to the telescopic rod 21, and the other end of the third connecting rod 33 is hinged to the first connecting rod 31, so as to specifically realize the hinge between the first connecting rod 31 and the telescopic rod 21. Here, the third connecting rod 33 and the telescopic rod 21 are fixedly connected by a first fixed shaft 331, and the third connecting rod 33 and the first connecting rod 31 are rotatably connected by a second fixed shaft 332.

[0045] like Figure 2 , Figure 4 As shown, a connecting plate 11 is provided on the fixed block 10, and the connecting plate 11 is in a right angle shape. One end of the second connecting rod 32 away from the first connecting rod 31 is rotatably mounted on the connecting plate 11, and the second connecting rod 32 is hinged to the fixed block 10. In this way, the hinge between the second connecting rod 32 and the fixed block 10 is specifically realized. In this way, the hinge of the second connecting rod 32 on the fixed block 10 is facilitated. Here, the second connecting rod 32 is attached to the connecting plate 11, and the connecting plate 11 and the fixed block 10 are fixed to the fixed block 10 by connecting members such as screws and bolts (not shown).

[0046] In the present application, the controller includes a trigger member, which can be triggered multiple times, and each time the trigger member is triggered, the movement stroke of the telescopic rod 21 when it is extended is consistent. In other words, the user can control the distance when the upper limit portion 301 of the connecting rod assembly extends out of the refrigerator body 200 by triggering the trigger member multiple times, so that when the depth adjustment mechanism 100 is applied to the refrigerator 1000, the refrigerator 1000 can be limited to different embedded depths in the cabinet. Here, the controller is integrated into the main control panel (not shown) of the refrigerator body 200, the trigger member is configured as a touch button, the wiring harness of the telescopic drive member 20 is connected to the main wiring harness of the refrigerator body 200, and the above-mentioned touch button is added to the operation panel of the display and control panel of the refrigerator compartment of the refrigerator body 200 through the program setting of the main control panel. The touch button is used to control the free telescopic adjustment of the telescopic rod 21 on the telescopic drive member 20, thereby linking the connecting rod assembly 30 to achieve free adjustment of the limit part 301. When the touch button is triggered once by the user, the forward displacement of the telescopic rod 21 in the telescopic drive member 20 is 5 mm. If the user continues to trigger the touch button, the telescopic rod 21 in the telescopic drive member 20 can be controlled to continue to move forward until the maximum distance. Of course, in other embodiments, the trigger member can also be configured as a push-type mechanical switch.

[0047] like Figure 1 , Figure 3 As shown, a refrigerator 1000 provided in an embodiment of the present application includes a refrigerator body 200 and the depth adjustment mechanism 100 described above, and the depth adjustment mechanism 100 is installed on the refrigerator body 200. Here, the depth adjustment mechanism 100 is installed in a press chamber 201 of the refrigerator body 200. Of course, in other embodiments, the depth adjustment mechanism 100 can also be assembled to other positions of the refrigerator body 200, such as the top of the refrigerator body 200.

[0048] like Figure 1 , Figure 3 As shown, the number of depth adjustment mechanisms 100 is configured as two sets, and the two sets of depth adjustment mechanisms 100 are arranged at intervals along the width direction of the refrigerator body 200. The refrigerator 1000 can use two sets of depth adjustment mechanisms 100 to adjust the embedding depth of the refrigerator 1000 in the cabinet, which can improve the stability of the refrigerator 1000 when the embedding depth in the cabinet is fixed. Of course, in other embodiments, the number of depth adjustment mechanisms 100 can also be configured as one set, three sets, or even more sets, which will not be elaborated here.

[0049] From the above, it can be seen that when the refrigerator 1000 of the present application needs to be embedded and installed in a cabinet, the refrigerator 1000 can be placed in the cabinet first until the outer surface of the refrigerator door on the refrigerator body 200 is flush with the cabinet; then the trigger part on the controller is operated to control the upper limit portion 301 of the connecting rod assembly 30 to extend from the refrigerator body 200 through the telescopic rod 21 on the telescopic drive part 20 until the limit portion 301 is against the wall.

[0050] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, 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.

[0051] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection required by the present invention.
