Description

[0001] The applicant declares that this application claims the priority of the Chinese patent application submitted to the China Patent Office on September 28, 2023, with application number "202322680120.8" and invention name "Refrigeration Equipment", all contents of which are incorporated into this application by introduction. Technical Field

[0002] The present application relates to the field of household appliances, and in particular to a connection device and a household appliance. Background Art

[0003] For home appliances such as built-in refrigerators, after the home appliances are installed, the color of the door body is inconsistent with the color of the surrounding home furnishings. In order to make the overall appearance of the home appliances more beautiful and coordinated after the embedded installation, it is generally necessary to install a door panel that is consistent with the color of the home furnishings on the door body of the home appliances. However, when installing the door panel, due to the preparation and installation errors of the connection structure between the door panel and the door body, there will be an error in the height of the door panel and the door body after the door panel is installed, which significantly reduces the user experience.

[0004] Therefore, it is necessary to provide a connecting device to solve the problem of height error between the door panel and the door body after installation. Utility Model Content

[0005] The present application aims to at least solve the problem of height errors that easily occur between the door panel and the door body after installation in the prior art or related art.

[0006] To this end, a first aspect of the present application is to provide a connecting device.

[0007] A second aspect of the present application is to provide a household appliance.

[0008] In order to achieve the above-mentioned objectives, an embodiment of the first aspect of the present application provides a connecting device for connecting a door body and a door panel, a supporting structure being installed on the door body, and the connecting device comprising: a connecting piece for connecting to the door panel; an adjusting disk rotatably mounted on the connecting piece, the adjusting disk being able to be supported and mounted on the supporting structure by the outer wall surface of the adjusting disk, and a plurality of distances being provided between the outer wall surface of the adjusting disk and the rotation axis of the adjusting disk; wherein a plurality of first positioning structures are provided on the adjusting disk, and the plurality of first positioning structures are spaced apart along the circumferential direction of the adjusting disk, the connecting device further comprising a second positioning structure, and the adjusting disk can be locked by any one of the first positioning structure and the second positioning structure.

[0009] According to the connection device provided by the present application, the connection device is used to connect the door body and door panel of the embedded household appliance, so that a door panel with a color close to that of the home furnishings around the household appliance can be additionally installed on the door body of the embedded household appliance. Among them, a support structure, such as a slide rail support structure, can be installed on the door body in advance. The connection device can be directly installed on the support structure to realize the installation of the door panel on the door body. Among them, the connection device includes an adjustment disk and a connector connected to the door panel. The adjustment disk can be rotatably installed on the connector. During installation, the side wall surface of the adjustment disk can be directly supported and installed on the support structure, that is, the outer wall surface of the adjustment disk is the support installation surface of the entire connection assembly. At the same time, there are multiple distances between the outer wall surface of the adjustment disk and the rotation axis of the adjustment disk, that is, the radial dimensions of the outer wall surface of the adjustment disk at different positions are different. Therefore, by rotating the adjustment disk, the outer wall surface of the adjustment disk at different positions can be used to support and install the entire connection device, so that the height position of the connector after being installed on the door body can be adjusted. Since the door panel is directly fixed to the connecting piece, the installation height position of the door panel can be adjusted by adjusting the installation height position of the connecting piece. When the door panel is installed on the door body, the installation height of the door panel can be adjusted by turning the adjusting dial. This can solve the problem of height errors that are easy to occur between the door body and the door panel after installation, thereby causing the height to be unable to be aligned.

[0010] Furthermore, a plurality of first positioning structures are arranged at intervals in the circumferential direction of the adjusting disk. In addition, the connecting device also includes a second positioning structure, and the adjusting disk can be locked by any of the first positioning structure and the second positioning structure. When the door body is installed, the adjusting disk can be supported by the side wall surfaces at different positions to adjust the installation height of the door panel. After the installation angle of the adjusting disk is determined, the first positioning structure corresponding to the corresponding angle can be used to cooperate with the second positioning structure to fix the adjusting disk at the current angle to achieve the locking of the adjusting disk. When the position of the adjusting disk is not suitable and the position needs to be readjusted, the cooperation between the first positioning structure and the second positioning structure can be released first, so that the rotating disk can rotate freely. With this structure, when adjusting the installation position of the door panel, it is only necessary to rotate the adjusting disk, and it is not necessary to remove the entire connecting device from the door panel, so that the operation of the adjustment process is more convenient, thereby reducing the difficulty of installing the door panel and improving the convenience of installing the door panel.

[0011] Furthermore, the adjusting disk comprises an eccentric disk which is eccentrically mounted on the connecting member. Through the eccentric mounting of the adjusting disk, a plurality of distances can be provided between the outer wall surface of the adjusting disk and the rotation axis of the adjusting disk.

[0012] In addition, the adjusting disk may be configured as a special-shaped disk so that there are multiple distances between the outer wall surface of the adjusting disk and the rotation axis of the adjusting disk.

With this arrangement, the installation height of the adjusting disk can be gradually increased by rotating the rotating disk, so that the installation height of the door panel can be gradually increased or decreased, so that the installation height of the door panel can be infinitely adjusted. In addition, this method can also expand the height adjustment range of the adjusting disk.

DETAILED DESCRIPTION

[0051] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0052] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0053] Refer to the following Figures 1 to 8 To describe the connection device 100 and household appliances provided according to some embodiments of the present application.

[0054] like Figure 1 As shown, in order to achieve the above-mentioned purpose, the embodiment of the first aspect of the present application provides a connecting device 100 for connecting the door body 52 and the door panel 6. Figure 5 As shown, a support structure 522 is installed on the door body 52. Figure 1 and Figure 2 As shown, the connecting device 100 includes: a connecting member 1, which is used to connect with the door panel 6; an adjusting disk 2, which can be rotatably mounted on the connecting member 1, and the adjusting disk 2 can be supported and mounted on the supporting structure 522 through the outer wall surface of the adjusting disk 2, and there are multiple distances between the outer wall surface of the adjusting disk 2 and the rotation axis L of the adjusting disk 2; wherein, a plurality of first positioning structures 22 are provided on the adjusting disk 2, and the plurality of first positioning structures 22 are arranged along the circumferential direction of the adjusting disk 2 (such as Figure 3 The connecting device 100 further includes a second positioning structure 142, and the adjusting disk 2 can be locked by any of the first positioning structure 22 and the second positioning structure 142.

[0055] According to the connection device 100 provided in the present application, the connection device 100 is used to connect the door body 52 and the door panel 6 of the embedded household appliance, so that an additional door panel 6 with a color close to the home furnishings around the household appliance can be installed on the door body 52 of the embedded household appliance. Among them, a support structure 522, such as a slide rail support structure 522, can be installed on the door body 52 in advance. The connection device 100 can be directly installed on the support structure 522 to achieve the installation of the door panel 6 on the door body 52. ​​Among them, the connection device 100 includes an adjustment disk 2 and a connection member 1 connected to the door panel 6. The adjustment disk 2 can be rotatably mounted on the connection member 1. During installation, the side wall surface of the adjustment disk 2 can be directly supported and installed on the support structure 522, that is, the outer wall surface of the adjustment disk 2 is the support installation surface of the entire connection assembly. At the same time, there are multiple distances between the outer wall of the adjusting disk 2 and the rotation axis L of the adjusting disk 2, that is, the radial dimensions of the outer wall at different positions of the adjusting disk 2 are different. Therefore, by rotating the adjusting disk 2, the entire connecting device 100 can be supported and installed through the outer wall at different positions of the adjusting disk 2, so that the height position of the connecting member 1 after being installed on the door body 52 can be adjusted. Since the door panel 6 is directly fixed to the connecting member 1, the height installation position of the door panel 6 can be adjusted by adjusting the installation height position of the connecting member 1. Therefore, when the door panel 6 is installed on the door body 52, the installation height of the door panel 6 can be adjusted by rotating the adjusting disk 2, so that the error in height between the door body 52 and the door panel 6 after installation can be solved, thereby solving the problem of height misalignment.

[0056] Furthermore, if Figure 2 and Figure 3 As shown, a plurality of first positioning structures 22 are arranged at intervals in the circumferential direction of the adjusting disk 2. Figure 1 and Figure 2 As shown, the connecting device 100 also includes a second positioning structure 142, and the adjusting disk 2 can be locked by any first positioning structure 22 and the second positioning structure 142. When the door body 52 is installed, the adjusting disk 2 can be supported by the side wall surface at different positions to adjust the installation height of the door panel 6. After determining the installation angle of the adjusting disk 2, the first positioning structure 22 corresponding to the corresponding angle can be used to cooperate with the second positioning structure 142 to fix the adjusting disk 2 at the current angle to achieve the locking of the adjusting disk 2. When the position of the adjusting disk 2 is not suitable and the position needs to be readjusted, the cooperation between the first positioning structure 22 and the second positioning structure 142 can be released first, so that the rotating disk can rotate freely. With this structure, when adjusting the installation position of the door panel 6, it is only necessary to rotate the adjusting disk 2, and it is not necessary to remove the entire connecting device 100 from the door panel 6, so that the operation of the adjustment process is more convenient, thereby reducing the installation difficulty of the door panel 6 and improving the convenience of the installation of the door panel 6.

[0057] Furthermore, the adjusting disk 2 includes an eccentric disk, which is eccentrically mounted on the connecting member 1. By eccentrically mounting the adjusting disk 2, a plurality of distances can be set between the outer wall surface of the adjusting disk 2 and the rotation axis L of the adjusting disk 2.

[0058] In addition, the adjusting disk 2 may also be configured as a special-shaped disk, so that there are multiple distances between the outer wall surface of the adjusting disk 2 and the rotation axis L of the adjusting disk 2 .

[0059] In the above embodiment, optionally, along the circumferential direction of the adjusting disk 2, the outer wall surface of the adjusting disk 2 and the rotation axis L of the adjusting disk 2 (such as Figure 2 The distance between them gradually increases.

[0060] In this embodiment, along the same circumferential direction of the adjusting disk 2, the distance between the outer wall surface of the adjusting disk 2 and the rotation axis L of the adjusting disk 2 gradually increases, for example, along the clockwise direction, the distance between the outer wall surface of the adjusting disk 2 and the rotation axis L of the adjusting disk 2 gradually increases, or along the counterclockwise direction, the distance between the outer wall surface of the adjusting disk 2 and the rotation axis L of the adjusting disk 2 gradually increases. With this arrangement, the installation height of the adjusting disk 2 can be gradually increased by rotating the rotating disk, so that the installation height of the door panel 6 can be gradually increased or decreased, so that the installation height of the door panel 6 can be infinitely adjusted. In addition, this method can also expand the height adjustment range of the adjusting disk 2.

[0061] In the above embodiment, if Figure 1 and Figure 2 As shown, the second positioning structure 142 is arranged on the connecting member 1 .

[0062] In this embodiment, the second positioning structure 142 can be arranged on the door panel 6, or on the door body 52. ​​However, by arranging the second positioning structure 142 on the connecting member 1, the structure of the door body 52 or the door panel 6 does not need to be changed, so that the door body 52 and the door panel 6 are easier to process, thereby reducing the processing cost of the entire product.

The structure for locking by the positioning pin 3 is relatively simple, so that the structure of the connecting device 100 can be simplified and the processing cost can be reduced. Of course, the first positioning structure 22 and the second positioning structure 142 can also be other structures, for example, the first positioning structure 22 and the second positioning structure 142 can be mutually locked buckle structures.

[0065] In any of the above embodiments, if Figure 2 and Figure 3 As shown, the adjusting plate 2 is provided with a first mounting hole 24, and the inner side wall of the first mounting hole 24 is provided with a first limiting rib 26 arranged along the circumferential direction of the first mounting hole 24.

[0081] In this embodiment, by providing the groove structure 5222, not only the adjustment disk 2 can be supported, but also the adjustment disk 2 can be blocked to prevent the adjustment disk 2 from sliding off the support structure 522, thereby ensuring the installation stability of the adjustment disk 2 on the support structure 522. In addition, this method can realize the hanging of the adjustment disk 2 on the support structure 522, and gravity can be used to make the adjustment disk 2 installed on the support structure 522 more stable.

[0082] In the above embodiment, optionally, the household appliance includes a refrigerator. Of course, the household appliance may also be other equipment with an opening and closing door, such as a disinfection cabinet, a smart locker, etc.

[0083] In the above embodiment, optionally, Figure 4 As shown, there are two or more connection devices 100. The two or more connection devices 100 can be arranged along the width direction of the home appliance, the support structure 522 has a certain length along the width direction of the home appliance, and the two or more connection devices 100 can be installed on the same support structure 522.

[0084] The following takes a refrigerator as an example to further introduce the connection device 100 and household appliances in the present application.

[0085] This embodiment proposes a cabinet panel mounted rotating slide adjustment device, the specific structure of which is as shown in 1 to Figure 8As shown, it includes a multi-stage adjustment slide assembly (i.e., a connecting device 100). When installing, the entire assembly is first connected to the cabinet panel (i.e., the door panel 6) by fixing screws. Two slide assemblies are installed at the upper design position of each cabinet panel. After installation, the entire cabinet panel is equivalent to being hung on the door body 52 of the refrigerator by two slide assemblies.

[0086] During assembly, the rotating adjusting disk 2 can be inserted into the connecting disk 12. There are three raised buckles on the top surface of the connecting disk 12. When inserted, corresponding notches are designed on the adjusting disk 2, and the aligned position can be smoothly slid in; there is a circle of flange edge at the bottom of the connecting disk 12, which cooperates with the adjusting disk 2 to axially position the adjusting disk 2; then the positioning chuck 14 is inserted into the connecting disk 12. At this time, the raised buckles and the positioning chuck 14 are interference fit and need to be forced in, and then the three can be assembled into a whole, making it faster and more convenient to install the cabinet panel.

[0087] After assembly, the positioning chuck 14 and the connecting disk 12 are engaged with each other through the raised buckles and positioning protrusions, and the two are relatively fixed. The adjusting disk 2 is axially positioned by the flange of the connecting disk 12 and the positioning chuck 14 and cannot move, but can rotate on the connecting disk 12.

[0088] When installing the cabinet panel, Figure 4 and Figure 5 As shown, drive the adjustment slide assembly into the cabinet panel through the three fixing screws, and then Figure 4 and Figure 5 As shown, hang the cabinet board from top to bottom on the plane of the inner groove of the stop bar, at this time, the bottom surface of the adjustment disk 2 and the stop bar surface are in contact with each other for support. If the height of the cabinet board is found to be inappropriate, remove the cabinet board and rotate the adjustment disk 2 to adjust it. The center hole of the dial is the rotating center hole. There are several holes around the center hole. The size and number of holes are not fixed. The size of the holes affects the size and strength of the overall structure. The number of holes determines the adjustment accuracy of the adjustment disk 2 each time the adjustment disk 2 is rotated. Figure 3 As shown, the supporting surface where the outer ring of the adjusting disk 2 contacts the baffle is composed of a curve that is not concentric with the center hole. The outline of the outer ring can be an N-polygon, which affects the adjustment accuracy. The difference between the maximum and minimum distances of the outer ring points from the center hole is the adjustable range.

[0089] like Figure 3 As shown, the maximum distance between the outer wall of the adjusting disk 2 and its rotation center is A, and the minimum distance is B. Therefore, the height range that the adjusting disk 2 can be adjusted is 0-(AB).

[0090] Each time when adjusting, after selecting a different adjustment height, align the holes of the adjustment disk 2 and the positioning chuck 14, insert the positioning pin 3 to clamp the adjustment disk 2 so that it cannot rotate and maintain the adjusted height.
