[0002] This invention claims priority to Chinese Patent Application No. 202322680120.8, filed on September 28, 2023, entitled "Refrigeration Equipment", the entirety of which is incorporated herein by reference. Technical Field

[0003] This invention relates to the field of refrigeration equipment technology, and more particularly to refrigeration equipment. Background Technology

[0004] In built-in home furnishings, cabinet panels are often added to enhance the overall style consistency, ensuring the appearance of the appliances matches the design. Taking refrigeration equipment as an example, the equipment is fixed to the cabinet panel using screws. Since these screws connect through fixed holes, the cabinet panel and the refrigeration equipment door remain fixed, moving synchronously during opening and closing. However, for doors that can rise and fall relative to the cabinet body during opening and closing, such as those with gravity-assisted opening and closing, the height adjustment is typically around 5mm. Given the small installation gaps (around 3mm) on the sides of the cabinet panel, if the cabinet panel and door rise and fall synchronously, the cabinet panel may interfere with the upper or lower structure of the cabinet, preventing the door from opening and closing smoothly. Therefore, the connection method between the door and the cabinet panel needs optimization. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in related technologies. To this end, this invention proposes a refrigeration device that can connect the cabinet panel and the door body through the cooperation of a limiting component and a sliding component. During the opening and closing of the door body, which can be raised and lowered relative to the cabinet body, the cabinet panel can be raised and lowered relative to the door body to ensure that the components at the upper and lower ends of the cabinet panel do not interfere with each other.

[0006] A refrigeration device according to an embodiment of the present invention includes:

[0007] The door body, the housing, and the hinge component are provided. The door body is hinged to the housing in a height-adjustable manner via the hinge component. The door body can be raised or lowered relative to the housing by a first preset height.

[0008] A cabinet panel and mounting components, wherein the cabinet panel is limited in height by the mounting components, and the mounting components are used to hinge the cabinet panel to an adjacent cabinet.

[0009] A limiting component is connected to one of the door body and the cabinet panel;

[0010] A sliding component is connected to the other of the door body and the cabinet panel. The sliding component is limited in the front-to-back direction by the limiting component. The sliding component is vertically connected to the limiting component. The sliding component can be raised or lowered relative to the limiting component by a second preset height. The second preset height is greater than or equal to the first preset height.

[0011] The refrigeration equipment according to an embodiment of the present invention includes a door body, a housing, a hinge component, a cabinet panel, a mounting component, a limiting component, and a sliding component. During the opening and closing of the door body, the door body rotates and rises / falls relative to the housing via the hinge component. The cabinet panel maintains a fixed height via the mounting component and can rotate and open / close synchronously with the door body. The door body and the cabinet panel generate relative movement in the height direction. During this process, the cabinet panel can rise / fall relative to the door body via the sliding component relative to the limiting component, maintaining a constant height. The cabinet panel will not interfere with adjacent cabinets, satisfying the requirement that the door body with the cabinet panel can rise / fall during opening and closing. It must be ensured that the second preset height at which the cabinet panel can rise / fall is greater than or equal to the first preset height at which the door body can rise / fall. The second preset height is the height at which the sliding component can rise / fall relative to the limiting component.

[0012] According to an embodiment of the present invention, the sliding component is provided with at least two support positions, and the distance from the different support positions to the mounting center of the sliding component is different. The sliding component and the limiting component switch between a separated state and a supported state. In the supported state, one of the support positions supports the limiting component. In the separated state, the support position is decoupled from the limiting component.

[0013] According to an embodiment of the refrigeration equipment of the present invention, the limiting component and the sliding component are in a separated state. The limiting component does not support the sliding component, and the limiting component and the sliding component do not interfere with the opening and closing of the door body. In the closed state of the door body, the limiting component and the sliding component cooperate to support the cabinet panel, ensuring the structural stability of the cabinet panel. When the door body switches from the closed state to the open state, the sliding component and the limiting component switch from the supporting state to the separated state; when the door body switches from the open state to the closed state, the sliding component and the limiting component switch from the separated state to the supporting state. The distance from the installation center of the sliding component varies at different support positions. When different support positions cooperate with the limiting component to provide support, the height position of the cabinet panel and the adjacent cabinet can be adjusted in the closed state, that is, the gap between the cabinet panel and the adjacent cabinet can be adjusted.

[0014] According to one embodiment of the present invention, the mounting component includes a hinge, one side of which is fixed to the cabinet panel, and the other side of which is used to connect to an adjacent cabinet.

[0015] According to one embodiment of the present invention, the mounting component includes a hinge shaft, a first end of which is connected to the cabinet panel, and a second end of which is used to connect to an adjacent cabinet. One of the first end and the second end of the hinge shaft is rotatably connected, while the other is fixedly connected.

[0016] According to one embodiment of the present invention, the limiting component includes a first limiting plate, a second limiting plate, and a third limiting plate. One end of the first limiting plate is connected to the second limiting plate. The first limiting plate is located on the front or rear side of the sliding component. The third limiting plate is located above or below the second limiting plate. In the supported state, the second limiting plate is supported by one of the supported positions. In the separated state, the upper limit of the sliding component in the height direction is located between the second limiting plate and the third limiting plate.

[0017] According to one embodiment of the present invention, the minimum distance between the second limiting plate and the third limiting plate is greater than or equal to the sum of the maximum height of the sliding component and the first preset height.

[0018] According to one embodiment of the present invention, the limiting component includes a guide limiting part and a support part. The support part is located at the upper end or the lower end of the guide limiting part. The guide limiting part is provided with a slide extending in the height direction and limiting the sliding component in the front-back direction. The support part and the support position switch between the support state and the separation state.

[0019] According to one embodiment of the present invention, the sliding member is movably connected to the guide limiting portion in the left-right direction.

[0020] According to one embodiment of the present invention, in the support position, the support position is supported by the surface of the limiting member.

[0021] According to one embodiment of the present invention, the sum of the distances from two oppositely arranged support positions to the installation center is a preset distance, and the preset distances of multiple sets of oppositely arranged support positions are equal.

[0022] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0051] When embedding refrigeration equipment, the equipment is decorated with style-matched cabinet panels. The design must consider the door body, which can be opened and closed. The cabinet panels are installed on the front side of the door body, serving both decorative and protective functions. Here, "front side" can be understood as the surface facing the user when the door body is closed. Other directional relationships, such as left and right, are also considered when the door body 200 is closed, not when it is open. Refrigeration equipment can include refrigerators, freezers, display cases, wine cabinets, etc.

[0052] refer to Figures 1 to 15As shown in the embodiment of the present invention, a refrigeration device is provided, including a door body 200, a cabinet 100, a hinge component 700, a cabinet panel 500, a mounting component 600, a limiting component 300, and a sliding component 400. The door body 200 is hinged to the cabinet 100 in a height-adjustable manner via the hinge component 700, and the door body 200 is adjustable up and down by a first preset height L2 relative to the cabinet 100. The cabinet panel 500 is limited in the height direction by the mounting component 600, which is used to hinge the cabinet panel 500 to an adjacent cabinet. The limiting component 300 is connected to one of the door body 200 and the cabinet panel 500. The sliding component 400 is connected to the other of the door body 200 and the cabinet panel 500, and is limited in the front-back direction by the limiting component 300. The sliding component 400 is height-adjustable to the limiting component 300, and the sliding component is adjustable up and down by a second preset height L2 relative to the limiting component. The second preset height L2 is greater than or equal to the first preset height L1.

[0053] First, connect one of the limiting component 300 and the sliding component 400 to the door body 200, and install the other on the cabinet panel 500. Then, the door body 200 and the cabinet panel 500 are connected by installing the limiting component 300 and the sliding component 400. During the installation of the limiting component 300 and the sliding component 400, the height position of the cabinet panel 500 relative to the door body 200 can be adjusted by adjusting the sliding component 400.

[0054] The door body 200 is hinged to the housing 100 via a hinge component 700. A height adjustment space is provided between the door body 200 and the hinge component 700. During the opening and closing of the door body 200, the door body 200 rises and falls relative to the housing 100.

[0055] Cabinet panel 500 is limited in height by mounting component 600. This means that cabinet panel 500 is held at a fixed height by mounting component 600, and cabinet panel 500 can be rotatably connected to adjacent cabinets via mounting component 600. During the opening and closing of cabinet panel 500 and door body 200, cabinet panel 500 does not rise or fall synchronously with door body 200 to avoid interference with cabinets above or below it. In other words, during the opening and closing of door body 200, cabinet panel 500 and door body 200 move relative to each other in height. The limiting component limits the sliding components forward and backward, ensuring that cabinet panel and door body open and close synchronously.

[0056] The second preset height L2 is greater than or equal to the first preset height L1, ensuring that the height of the cabinet panel relative to the door body is greater than or equal to the height of the door body, thus avoiding interference between the door body and the cabinet panel during the lifting process and ensuring that the door body can be lifted and lowered stably.

[0057] in, Figure 4Taking a door body connected to a limiting component 300 and a cabinet panel connected to a sliding component 400 as an example. Figure 4 The central door body 200 is at its maximum height, and correspondingly, the limiting component 300 is also at its maximum height. Figure 4 The maximum height that the limiting component 300 can descend is indicated by the dotted line as the first preset height L1. The first preset height L1 only simply indicates the height that the lower end of the limiting component 300 can descend, and does not indicate other parts of the limiting component. Figure 4 The diagram also illustrates that the maximum height that the sliding component 400 can be raised or lowered is the second preset height L2. The first preset height L1 is generally 5mm, and the second preset height L2 can be any value greater than or equal to 5mm. It should be noted that... Figure 4 The diagram illustrates that both the upper and lower ends of the limiting component 300 can limit the sliding component 400. The second preset height L2 has an upper limit, such as 10mm. However, if the upper end of the limiting component does not limit the upper end of the sliding component, then the second preset height L2 has no upper limit and can be infinitely large in the absence of other influencing factors. It should also be noted that the lower end of the limiting component may not limit the height of the sliding component; the lifting and lowering of the sliding component is not restricted by the limiting component, which only needs to limit its movement forward and backward. (Reference) Figure 5 As shown, both the upper and lower ends of the limiting component 300 can limit the sliding component 400. Both the upper and lower ends of the sliding component 400 are provided with gaps between themselves and the limiting component 300. The sum of the gap between the upper end of the sliding component 400 and the top of the limiting component and the gap between the lower end of the sliding component 400 and the bottom of the limiting component is the second preset height L2.

[0058] The refrigeration equipment of this invention uses a limiting component 300 and a sliding component 400 to achieve front and rear positioning of the cabinet panel and the door body. The cabinet panel is hinged to the adjacent cabinet through an installation component to ensure that the cabinet panel can open and close synchronously with the door body. The cabinet panel is held at a fixed height position by the installation component. During the opening and closing of the door body, the cabinet panel does not rise and fall synchronously with the door body to avoid interference between the cabinet panel and the adjacent cabinet. Furthermore, the second preset height at which the limiting component and the sliding component can rise and fall relative to each other is greater than or equal to the first preset height at which the door body can rise and fall, to avoid interference between the cabinet panel and the door body in the height direction and to ensure stable opening and closing of the door body.

[0059] It is also understood that the sliding component 400 is provided with a support position 411. The sliding component 400 and the limiting component 300 switch between a separated state and a supported state. In the supported state, the support position 411 supports the limiting component 300 and the door body 200 is in a closed state. In the separated state, the support position 411 and the limiting component 300 are released from support and the door body 200 is in an open state.

[0060] The door body 200 is normally in the closed state. When the door body 200 is closed, the limiting component 300 and the sliding component 400 support each other (see reference). Figure 4 As shown), this ensures the connection stability between the door body 200 and the cabinet panel 500, reduces the load on the mounting component 600, and helps extend the life of the mounting component 600. When the door body 200 needs to be opened, it switches to the open state. During the opening process, the door body 200 moves up and down relative to the hinge component 700. At this time, the cabinet panel 500 rotates with the door body 200, and the height position of the cabinet panel 500 remains fixed. The rising and falling of the door body 200 releases the support of the limiting component 300 and the sliding component 400 (see reference). Figure 5 As shown, there is a gap between the limiting component 300 and the support position 411 of the sliding component 400.

[0061] It is also understood that the sliding component 400 is provided with at least two different support positions 411, and the distance from the mounting center of the sliding component 400 is different for each support position 411. The sliding component 400 and the limiting component 300 switch between a separated state and a supported state. In the supported state, one of the support positions 411 supports the limiting component 300. (Reference) Figure 4 and Figure 5 As shown, the sliding component 400 and the limiting component 300 switch between a separated state and a supported state. In the supported state, one of the supporting positions 411 supports the limiting component 300, and the door body 200 is in a closed state. By switching different supporting positions 411, the support function can be achieved, and the gap between the cabinet panel 500 and the adjacent cabinet in the height direction can be adjusted to ensure that the gap between the cabinet panel 500 and the adjacent cabinet in the height direction (such as the gap being controlled within 3mm) meets the installation requirements and ensures that the cabinet panel 500 can be accurately installed onto the door body 200.

[0062] The phrase "the distance from different support positions 411 to the mounting center of the sliding component 400 is different" can be understood as referring to... Figure 10 As shown, the support position 411 is located at the outer edge of the sliding component 400. Since the height of the mounting center o and the cabinet panel 500 remains constant, the distance from the support position 411 to the mounting center o varies, and the distance from the mounting center to the limiting component 300 also changes. Therefore, the height of the support position 411 and the limiting component 300 supported by the support position 411 differs, thus achieving height adjustment of the cabinet panel 500. The mounting center o is located on the axis of rotation adjustment of the sliding component 400. The mounting center o can be understood as a virtual center, not the actual center of the sliding component 400. (Reference) Figure 10 As shown, the inward and outward directions of the support position 411 can be understood as follows: the side closer to the installation center o is the inner side, and the side farther from the installation center o is the outer side.

[0063] The number of different support positions 411 is equivalent to the number of height adjustment positions. If the sliding component 400 has four support positions 411 and two of them are different, it has two adjustment positions. If the sliding component 400 has four support positions 411 and four of them are different, it has four adjustment positions. When the sliding component 400 has four support positions 411 and two of them are different, the other two support positions 411 can each have the same structure as one of the support positions 411, or two of each type of support position 411 can be provided. If the sliding component 400 has multiple support positions 411 of a certain type, if one of these support positions 411 is deformed or damaged, the other support position 411 can be switched to support the limiting component 300, thus satisfying the support and adjustment requirements without replacing the sliding component 400. Of course, if the sliding component 400 has two support positions 411, these two support positions 411 are not the same.

[0064] The refrigeration equipment may be equipped with a sliding component 400 of the same size, or the refrigeration equipment may be equipped with at least two sliding components 400 of different sizes, thereby increasing the number of height adjustment levels by replacing the sliding component 400.

[0065] The height direction can be perpendicular to or approximately perpendicular to the horizontal plane. In other words, this embodiment does not impose strict requirements on the height direction (the deviation in the height direction can be due to manufacturing errors or design requirements). For example, an angle between 85 and 95 degrees with the horizontal plane can be considered as the height direction.

[0066] The limiting component 300 at least limits the sliding component 400 in the front, and the sliding component 400 can be limited in the rear by the limiting component 300 or the surface of the door body 200.

[0067] The refrigeration equipment of this invention includes a door body 200, a hinge component 700, a cabinet panel 500, a mounting component 600, a limiting component 300, and a sliding component 400. In the closed state, the limiting component 300 and the sliding component 400 cooperate to support and limit the cabinet panel 500 and the door body 200 in the height direction, ensuring the connection stability between the cabinet panel 500 and the door body 200. During opening and closing, the door body 200 can rise and fall relative to the hinge component 700. Through the limiting component 300 and the sliding component 400, the support between the door body 200 and the cabinet panel 500 in the height direction can be released, keeping the cabinet panel 500 at a fixed height position and preventing interference between the cabinet panel 500 and its upper or lower structure. This is suitable for door bodies that open and close with gravity assistance. By switching different support positions 411 and the limiting component 300, the height position of the cabinet panel 500 can be adjusted in the closed state, ensuring accurate installation of the cabinet panel 500 and the door body 200.

[0068] Regarding installation component 600:

[0069] Understandably, reference Figure 2 As shown, the mounting component 600 includes a hinge, one side of which is fixed to the cabinet panel 500, and the other side of which is used to connect to an adjacent cabinet. The hinge keeps the cabinet panel 500 at a fixed height, resulting in a simple structure and easy installation.

[0070] Understandably, reference Figure 3 As shown, the mounting component 600 includes a hinge shaft. The first end of the hinge shaft is connected to the cabinet panel 500, and the second end of the hinge shaft is used to connect to an adjacent cabinet. One of the first and second ends of the hinge shaft is rotatably connected, while the other is fixedly connected. The cabinet panel 500 is connected to its adjacent cabinet via the hinge shaft, resulting in a simple structure and easy installation.

[0071] The structure of mounting component 600 is not limited to the aforementioned hinges and hinge shafts; other structures that can achieve rotatable connection and height limitation are also acceptable, and will not be listed here.

[0072] refer to Figure 6 and Figure 7 As shown, the door body 200 is provided with end caps and uprights 230. Uprights 230 are provided at both ends of the end caps, and the uprights 230 are divided into left uprights and right uprights. The end caps are provided at the upper and lower ends of the uprights 230, and the end caps are divided into upper end caps 220 and lower end caps 210. The mounting component 600 is connected to at least one of the uprights 230 and the end caps.

[0073] Regarding the limit component 300:

[0074] The first implementation method, as described in the reference... Figure 4 and Figure 5As shown, the limiting component 300 includes a first limiting plate 310, a second limiting plate 320, and a third limiting plate 360. One end of the first limiting plate 310 is connected to the second limiting plate 320. The first limiting plate 310 is located in front of or behind the sliding component 400. The third limiting plate 360 ​​is located above or below the second limiting plate 320. The second limiting plate 320 and the third limiting plate 360 ​​cooperate to limit the height, so as to ensure the relative lifting accuracy of the door body 200 and the cabinet panel 500.

[0075] Taking the second limiting plate 320 located below the third limiting plate 360 ​​as an example, refer to... Figure 4 As shown, in the supported state, the second limiting plate 320 is supported by one of the supporting positions 411, for reference. Figure 5 As shown, in the separated state, the upper limit of the sliding component 400 in the height direction is located between the second limiting plate 320 and the third limiting plate 360.

[0076] It is understandable that the minimum distance between the second limiting plate 320 and the third limiting plate 360 ​​is greater than or equal to the sum of the maximum height of the sliding component and the first preset height. The first preset height is the lifting height of the door body 200, and the difference between the minimum distance between the second limiting plate 320 and the third limiting plate 360 ​​and the maximum height of the sliding component is the second preset height at which the sliding component can be lifted and lowered, ensuring that the door body 200 can be lifted and lowered stably.

[0077] Understandably, reference Figure 4 and Figure 5 As shown, the limiting component 300 includes a first limiting plate 310 and a second limiting plate 320 connected to the lower end of the first limiting plate 310. The first limiting plate 310 is disposed on the front side of the second limiting plate 320 and forms an angle with the second limiting plate 320. The first limiting plate 310 limits the front side of the sliding component 400, and the second limiting plate 320 supports one of the support positions 411.

[0078] Combination Figure 4 , Figure 5 and Figure 6 As shown, the first limiting plate 310 and the second limiting plate 320 extend along the width direction on the front side of the door body 200. The first limiting plate 310 and the second limiting plate 320 cooperate to form a slide rail extending along the width direction. The slide rail can be understood as a slide rail or a slide groove. The sliding component 400 can move along the slide rail or slide groove in the width direction to install the sliding component 400 in place, and can also adjust the position of the cabinet panel 500.

[0079] It is understandable that the upper surface of the second limiting plate 320 and the end face of the support position 411 support each other. Compared with point contact or line contact, surface support can increase the contact area, resulting in better support stability and load-bearing capacity, which helps to improve the connection stability between the cabinet panel 500 and the door body 200.

[0080] Understandably, reference Figure 6 As shown, the door body 200 is provided with end caps (upper end cap 220 and / or lower end cap 210). A first limiting plate 310 and a second limiting plate 320 extend along the end caps and are connected to the front side of the end caps. The limiting component 300 occupies the space on the front side of the end caps, which can reduce the impact on the volume of the internal insulation layer of the door body 200. The first limiting plate 310 and the second limiting plate 320 are installed on the end caps, and the structure of the end caps is adaptively adjusted without affecting the structure of other components of the door body 200.

[0081] Of course, the door body 200 is provided with pillars 230, and the first limiting plate 310 and the second limiting plate 320 can also be fixedly connected to the two pillars 230 at the left and right ends. The installation position of the first limiting plate 310 and the second limiting plate 320 is flexible and can be adjusted according to the actual situation.

[0082] refer to Figure 6 As shown, when the upper end cover 220 is connected to the limiting component 300, multiple ribs protrude from the front side of the upper end cover 220. The front end face of the ribs contacts and limits the sliding component 400 at the rear end face. The ribs limit the sliding component 400 from the rear, and the first limiting plate 310 limits the sliding component 400 from the front, ensuring the stability of the sliding component 400 in the front-rear direction. At this time, the limiting component 300 does not need to be provided with a rear wall plate, which simplifies the structure of the limiting component 300 and reduces the thickness of the limiting component 300, thereby reducing the gap between the door body 200 and the cabinet panel 500.

[0083] Furthermore, the raised ribs can strengthen the end cap and ensure that the thickness of the end cap is not reduced. Based on the injection molding of the end cap, the front surface of the raised ribs has good flatness, which makes the sliding component 400 move more smoothly between the first limiting plate 310 and the end cap.

[0084] It is understandable that the upper end cover 220 is provided with a limiting surface, which is limited to at least one of the lower end, left end and right end of the first limiting plate 310 and the second limiting plate 320, so as to ensure that at least one end of the first limiting plate 310 and the second limiting plate 320 is positioned by the end cover, which facilitates positioning and installation.

[0085] The upper cover 220 is provided with a first limiting surface 240, and the bottom surfaces of the first limiting plate 310 and the second limiting plate 320 are limited by the first limiting surface 240. It can also be understood that the upper cover 220 is provided with a recessed platform, which positions and supports the first limiting plate 310 and the second limiting plate 320, making it convenient for the first limiting plate 310 and the second limiting plate 320 to be installed and positioned.

[0086] It is also understandable that the upper cover 220 is provided with a second limiting surface 250, and the left or right side of the first limiting plate 310 and the second limiting plate 320 is limited by the second limiting surface 250. Two second limiting surfaces 250 can be provided, one limiting the left side of the first limiting plate 310 and the second limiting plate 320, and the other limiting the right side of the first limiting plate 310 and the second limiting plate 320.

[0087] The upper end cover 220 can be provided with a first limiting surface 240 and a second limiting surface 250 simultaneously. The lower, left, and right sides of the first limiting plate 310 are all limited, and the first limiting plate 310 can be accurately positioned and installed with the end cover. Similarly, the lower end cover 210 can be provided with at least one of the first limiting surface 240 and the second limiting surface 250.

[0088] The installation method of the third limiting plate can refer to that of the second limiting plate and the first limiting plate.

[0089] The limiting component 300 can be fixedly connected to the end cap by the second fastener 350, which is easy to install and has a simple structure.

[0090] It is understood that the extension direction of the second limiting plate 320 supports multiple sliding components 400, and the minimum distance from different support positions 411 to the mounting center of the sliding component 400 may be the same or different. Each sliding component 400 is supported by the second limiting plate 320, and the distance from the support position 411 of each sliding component 400 to the mounting center may be the same or different. Each sliding component 400 can be adjusted independently, allowing for flexible adjustment.

[0091] Understandably, the limiting component 300 forms a slide with a T-shaped longitudinal section, which can not only stabilize and limit the sliding component 400, but also facilitate the connection between the sliding component 400 and the cabinet panel 500.

[0092] When the sliding component 400 includes an adjusting part 410 and a main body 420, the main body 420 is used to connect the cabinet panel 500, the outer ring of the adjusting part 410 is connected to the support position 411, the center of the main body 420 is the installation center o, and a gap is provided between the main body 420 and the limiting component 300. The main body 420 does not contact the limiting component 300 for support, and the support position 411 cooperates with the limiting component 300 for support, thereby reducing contact friction.

[0093] In the above embodiments, the upper end cover 220 and the lower end cover 210 may each be provided with a set of sliding components 400 and limiting components 300 to ensure the installation stability of the door body 200 and the cabinet panel 500 in the height direction.

[0094] The second embodiment of the limiting component 300:

[0095] refer to Figure 7 and Figure 8 As shown, the limiting component 300 includes a guide limiting part 330 and a support part 340. The support part 340 is located at the upper or lower end of the guide limiting part 330. The guide limiting part 330 is provided with a slide extending in the height direction and limits the sliding component 400 in the front and back direction. The support part 340 and the support position 411 switch between a support state and a separation state.

[0096] The guide limiting part 330 extends along the height direction and forms a slide rail extending along the height direction. The guide limiting part 330 is disposed above the support part 340 and limits the front side of the sliding member 400. The support part 340 supports one of the support positions 411. The guide limiting part 330 is provided with a slide rail extending along the height direction, and the upper end of the slide rail is open. The sliding member 400 can slide from the upper end of the guide limiting part 330 along the slide rail until it is supported by the support part 340.

[0097] refer to Figure 7 and Figure 8 As shown, the guide limiting part 330 can be understood as a vertical guide rail. The vertical guide rail extends along the height direction, and an opening is provided at the upper end of the vertical guide rail to facilitate the sliding part 400 entering the vertical guide rail through the opening, thereby realizing the connection and limiting of the sliding part 400 with the guide limiting part 330. When the vertical guide rail is provided with a slide rail with a T-shaped groove in cross-section, the sliding part 400 passes through the opening on the front side of the slide rail to connect with the cabinet panel 500.

[0098] In some cases, the limiting component 300 may only have a guide limiting part 330 and no support part is required. The structure of the guide limiting part can be referred to the above content.

[0099] refer to Figure 7 As shown, when the sliding component 400 includes a body part 420 and an adjusting part 410, the body part 420 is used to connect the cabinet panel 500. The body part 420 is movably connected to the opening on the front side of the guide limiting part 330. The outer contour of the adjusting part 410 is provided with a support position 411. The front side of the support position 411 is limited by the wall panel of the guide limiting part 330. The connection method between the sliding component 400 and the cabinet panel 500 is simple and can ensure that the sliding component 400 can move and adjust stably in all directions within the guide limiting part 330.

[0100] refer to Figure 7As shown, the main body 420 protrudes forward from the adjusting part 410. The guide limiting part 330 includes a first limiting part 331 and a second limiting part 332 that are arranged opposite each other in the left-right direction and have a distance between them. In the left-right direction, the main body 420 can move between the first limiting part 331 and the second limiting part 332 and be limited forward by the first limiting part 331 and the second limiting part 332. By limiting the left-right direction through the main body 420, the adjusting part 410 can be spaced from the guide limiting part 330 in the left-right direction, reducing the contact friction of the support position 411 moving in the height direction within the guide limiting part 330.

[0101] It is understandable that the sliding component 400 moves and adjusts in the left and right directions of the guide limiting part 330, which is the width direction. The sliding component 400 can move and adjust relative to the guide limiting part 330 in the width direction. During the movement of the sliding component 400, the support part 340 provides support to the support position 411, and the guide limiting part 330 limits the sliding component 400 in the front.

[0102] Understandably, reference Figure 7 As shown, multiple sliding parts 400 are slidably connected in the height direction of the limiting part 300. A support part 340 is provided at the lower end of the guide limiting part 330, and the support position 411 of the lowermost sliding part 400 is supported by the support part 340.

[0103] In each of the above embodiments, a set of sliding components 400 and limiting components 300 may be provided at the left and right ends of the end cap to ensure the installation stability of the door body 200 and the cabinet panel 500 in the width direction.

[0104] Understandably, in the supported state, the support position 411 and the limiting component 300 support each other, resulting in good support stability and balanced force distribution.

[0105] Understandably, reference Figure 8 and Figure 9 As shown, the door body 200 is provided with a lower end cover 210, and the lower end cover 210 is formed with a support portion 340. The support position 411 is supported by the lower end cover 210, and the top surface of the lower end cover 210 is fully utilized, which can reduce the number of parts.

[0106] Understandably, reference Figures 7 to 9 As shown, the upper end of the support portion 340 forms a support surface, which supports the support position 411 below and against the surface of the support position 411, providing good support stability. The support portion 340 is a support plate disposed on the upper end of the end cap. The upper surface of the support plate forms a support surface, and the front end of the support plate protrudes a predetermined length relative to the front end of the mounting portion to provide installation space for the limiting component 300. The support plate can also support the limiting component 300.

[0107] Of course, the pillar 230 can also be formed with a support part 340. The pillar 230 has guiding and limiting functions and supporting functions. The functions of the pillar 230 are more diverse, which helps to simplify the structure of the door body.

[0108] Understandably, reference Figure 7 As shown, the pillar 230 is integrally formed with a guide limiting part 330. The pillar 230 includes a left pillar and a right pillar. At least one of the left and right pillars is integrally formed with the guide limiting part 330, which reduces the number of parts. The pillar 230 has multiple functions, which simplifies the assembly of the door body 200. When the lower end cover 210 is provided with a support part 340, the door body 200 only needs to add one part, the sliding part 400, which reduces the number of accessories of the door body 200 and simplifies installation. The door body 200 is provided with an end cover, and the pillar 230 is connected to the end cover through the guide limiting part 330. The connection method between the pillar 230 and the end cover is simple.

[0109] Understandably, reference Figure 7 As shown, the door body 200 is provided with an upper end cover 220, and the upper end cover 220 and the lower end cover 210 are detachably connected to the guide limiting part 330. The guide limiting part 330 can be disassembled and replaced as needed. At this time, the guide limiting part 330 and the column 230 can be integrally formed or independent of each other.

[0110] Regarding sliding component 400:

[0111] It is understandable that the support positions 411 are located on different sides of the sliding component 400. When the sliding component 400 is provided with four sides, support positions 411 are provided on at least two sides to facilitate the differentiation of each support position 411 and to facilitate accurate adjustment to the target position.

[0112] The sliding component 400 is a quadrilateral sliding component 400, and the outer contour of the sliding component 400 is provided with four sides. Support positions 411 are provided on different sides of the sliding component 400. Support positions 411 are provided on two, three or four sides of the sliding component 400. The support positions 411 are located on different sides of the sliding component 400. The number of support positions 411 is less than or equal to four and greater than or equal to two, and at least two support positions 411 are different.

[0113] The quadrilateral sliding component 400 can be a quadrilateral or approximately quadrilateral structure. The outer contour of the quadrilateral sliding component 400 includes four sides, each of which can be straight or curved. The shape of each side is not limited; for example, at least one side may extend along a straight line, and at least one side may extend along an arc. The shape of the sliding component 400 can be rectangular, trapezoidal, parallelogram, or rhomboid, etc. The specific shape of the sliding component 400 is not limited and will not be listed here. Adjacent sides of the sliding component 400 may be chamfered. If the shape of the sliding component 400 is square, the mounting center does not coincide with the center of the square to ensure that the sliding component 400 has at least two support positions 411. Figure 10 The installation center o is marked by a black dot in the figure. The distances from the different support positions 411 to the installation center are marked as a1, a2, a3 and a4 in the figure.

[0114] It is understood that when the sliding component 400 includes a body portion 420 and an adjusting portion 410, with a support position 411 at its outer end, and the body portion 420 used to connect to the cabinet panel 500, the adjusting portion 410 is connected to the outer edge of the body portion 420. The adjusting portion 410 cooperates with the body portion 420 to make the outer contour shape of the sliding component 400 quadrilateral. Here, the outer edge can be understood as the edge of the sliding component 400 away from the mounting center. The inward and outward directions of the sliding component 400 can be understood as the inner side being closer to the mounting center and the outer side being farther from the mounting center.

[0115] Understandably, the minimum distance from the outer edge of different adjustment parts 410 to the mounting center of the main body 420 is different. The main body 420 connects to the cabinet panel 500, and the mounting center of the sliding part 400 is located on the main body 420, facilitating positioning and installation of the sliding part 400 and the cabinet panel 500. In some cases, the distance from the edge of the main body 420 to the mounting center is equal. The outer contour shape of the main body 420 can be a circle, an equilateral triangle, a square, or other regular polygons, and the mounting center is the center of the main body 420.

[0116] The two different support positions 411 can be referred to as the first support position and the second support position. The vertical distance from the first support position to the mounting center o of the main body 420 is the first distance, and the vertical distance from the second support position to the mounting center o of the main body 420 is the second distance. The first distance and the second distance are different. The difference between the two different support positions 411 is that the first distance and the second distance are different. Taking one of the first distance and the second distance as a reference position, the difference between the first distance and the second distance is an adjustment value in a preset direction.

[0117] The first support position and the second support position can be located on opposite sides of the body portion 420, which can be understood as being opposite sides along at least one of the height direction and the width direction. Of course, the first support position and the second support position can also be located on adjacent sides of the body portion 420.

[0118] It is understandable that the sum of the distances from the two relatively set support positions 411 to the installation center is the preset distance, and the preset distances of multiple sets of relatively set support positions 411 are equal.

[0119] When the first support position and the second support position are located on opposite sides of the main body 420, the first support position and the second support position form an adjustment group. The main body 420 is connected to multiple adjustment groups, and the sum of the first distance and the second distance of the multiple adjustment groups is the same, that is, the preset distances of different adjustment groups are equal, so that the distance between the end faces of the sliding member 400 in each opposite direction is the same. (Refer to...) Figure 10 In the equation, a1+a4=a2+a3. Based on the fact that the sliding component 400 is movably connected to the limiting component 300 in the width direction, if the limiting component 300 is provided with a slide rail that limits both ends (such as the upper and lower ends, or the left and right ends) along a preset direction (height direction or width direction), any support position 411 supporting the limiting component 300 can ensure that the sliding component 400 enters the slide rail and moves and adjusts within the slide rail.

[0120] Understandably, different adjustment groups have different first distances, providing more adjustment positions. In some cases, different adjustment groups also have different second distances, providing even more adjustment positions.

[0121] refer to Figure 10 As shown, the sliding component 400 is equipped with two adjustment groups. The first and second distances of the two adjustment groups are different, resulting in four different support positions 411; a1 and a2 are not equal, and a3 and a4 are not equal. a1 + a4 = a2 + a3. (Reference) Figure 12 As shown, the sliding component 400 is provided with an adjustment group, with different first and second distances, and two different support positions 411. That is, four support positions 411 are provided on the outer periphery of the sliding component 400, each support position 411 is at a different distance from the mounting center, and the vertical distance between the relatively set support positions 411 is equal.

[0122] Understandably, reference Figures 10 to 14 As shown, three or four support positions 411 are sequentially arranged on the outer ring of the main body 420. The lower support position 411 is supported by the limiting member 300, and the left and / or right support positions 411 can be limited by the limiting member 300.

[0123] When four support positions 411 are sequentially arranged on the outer ring of the main body 420, the maximum vertical distance between two support positions 411 arranged opposite each other along the height direction is the first length, and the maximum vertical distance between two support positions 411 arranged opposite each other along the left and right directions is the second length. The first length and the second length are equal. Figure 10 In the equation, a1 + a4 = a2 + a3. After switching the support position 411 that supports the limiting component 300, it is ensured that the support position 411 in the left and right directions will not interfere with the limiting part.

[0124] Understandably, reference Figure 10 As shown, two different support positions 411 are provided on opposite sides of the main body 420; or, refer to Figure 12 As shown, two different support positions 411 are provided on adjacent sides of the main body 420. The positions of the different support positions 411 are flexible and can be selected as needed.

[0125] Understandably, reference Figure 10 and Figure 12 As shown, support positions 411 are equipped with adjustment distance markings 430. The minimum distance to the installation center is called the reference distance, and the adjustment distance marking 430 for the support position 411 corresponding to the reference distance is 0mm. The difference between the distance from other support positions 411 to the installation center and the reference distance is the corresponding adjustment distance marking 430 for the support position 411, such as 2mm, 3mm, etc. The adjustment distance markings 430 correspond one-to-one with the support positions 411.

[0126] refer to Figure 10 As shown, the sliding component 400 has four support positions 411. The distance from the outer contour of each support position 411 to the mounting center of the main body 420 is different, with the minimum distance being 0mm as the reference distance. The adjustable distances of each support position 411 can be 0mm, 0.2mm, 2.8mm, and 3.0mm respectively. 0mm and 3.0mm are set opposite each other. Of course, other adjustment precisions such as 0mm, 0.1mm, 0.15mm, and 0.2mm can be freely selected. The adjustable distances of the support positions 411 set opposite each other in the same direction are all equal, so that the mating clearance between each sliding component 400 and the slide rail in the limiting part is the same in the left and right directions, which can minimize the distance of the slide rail in the left and right directions.

[0127] It is understandable that the main body 420 and the adjustment part 410 are integrally formed, the sliding part 400 has good integrity and structural stability, and the number of parts can be reduced.

[0128] In some cases, the main body 420 and the adjusting part 410 are detachably connected. Without removing the main body 420 from the cabinet panel 500, the adjusting part 410 can be connected and disconnected from the main body 420 to switch the support position 411 supported by the limiting component 300, thereby adjusting the height adjustment range. If the main body 420 and the cabinet panel 500 are connected by threads, the problem of stripping threads caused by frequent removal of the main body 420 from the cabinet panel 500 can be solved. The detachable connection between the main body 420 and the adjusting part 410 can be understood as the main body 420 being detachably connected to at least one adjusting part 410. The main body 420 and the adjusting part 410 can be detached and connected by snap-fit, hook-fit, threaded connection, etc. Various methods of detachment and assembly are available, and can be selected according to needs.

[0129] Understandably, reference Figures 10 to 14 As shown, multiple adjustment parts 410 are integrally formed. The support position 411 of the adjustment part 410 and the limiting component 300 support each other. The outer end face of the adjustment part 410 and the limiting component 300 support each other. The outer end faces of adjacent adjustment parts 410 are connected by an arc-shaped surface, and the outer end faces of the adjustment parts 410 transition with an arc shape. During disassembly and assembly, this avoids accidental injury to operators, saves materials, and reduces processing costs. Of course, if each adjustment part 410 is an independent part, the outer end faces of adjacent adjustment parts 410 can also transition with an arc-shaped surface.

[0130] In some cases, refer to Figure 12 As shown, the outer end faces of multiple adjustment parts 410 are connected end to end, and the multiple outer end faces are connected in sequence to form a closed loop outer contour surface. The outer contour surface of the adjustment part 410 has a larger area and better support stability.

[0131] It is understood that the body portion 420 of the sliding component 400 is provided with a mounting position, through which the sliding component 400 is connected to the cabinet panel 500. The structural form of the mounting position is not limited. The mounting position can be a mounting hole 421, through which the sliding component 400 is connected to the cabinet panel 500 by a first fastener 440 passing through the mounting hole 421. The mounting position can also be a first snap-fit ​​portion, through which the sliding component 400 is snapped and fixed to the cabinet panel 500 by a second snap-fit ​​portion.

[0132] refer to Figure 10As shown, taking mounting hole 421 as an example, the main body 420 can be provided with one or more mounting holes 421; when one mounting hole 421 is provided, the center of the mounting hole 421 can be located at the mounting center or the outer periphery of the mounting center; when the center of the mounting hole 421 is located at the mounting center, it is fixed to the target position of the cabinet panel 500 by the first fastener 440 passing through the mounting hole 421, and by loosening the first fastener 440, the support position 411 of the adjustment part 410 supported by the limiting member 300 can be rotated and switched, based on the adjustment part 41 The outer end face of the sliding component 400 supports the limiting component 300. Only one mounting hole 421 is needed to accurately switch the support position 411. When a mounting hole 421 is located on the outer periphery of the mounting center, the cabinet panel 500 needs to be equipped with multiple mating holes. The number of mating holes is the same as the number of support positions 411. By adjusting the position of the sliding component 400, the mounting hole 421 is switched to be connected to the corresponding mating hole through the first fastener 440, thereby switching the support position 411 supported by the limiting component 300, which simplifies the structure of the sliding component 400.

[0133] When multiple mounting holes 421 are provided, and these mounting holes 421 are centrally symmetrically distributed around the mounting center, a mounting hole 421 may or may not be provided at the mounting center. The cabinet panel 500 may be provided with one or more mating holes. When multiple mounting holes 421 are provided and the cabinet panel 500 is provided with one mating hole, the number of mounting holes 421 is the same as the number of support positions 411. By adjusting the position of the sliding component 400, the mounting holes 421 that are fastened to the mating holes are switched, thereby switching the support position 411 that supports the limiting component 300. When multiple mounting holes 421 are provided and the cabinet panel 500 is provided with multiple mating holes, the number of mounting holes 421 and mating holes may be the same or different.

[0134] refer to Figure 13 As shown, the mounting hole 421 is a countersunk hole. The sliding component 400 is physically connected to the cabinet panel 500 by a countersunk screw passing through the countersunk hole. The countersunk screw will not protrude from the plane of the sliding component 400. The use of countersunk screws can prevent the sliding component 400 from rubbing against the limiting component 300 or the door body 200 when it moves, and the limiting component 300 or the door body 200 does not need to be thickened to allow the countersunk screw to pass through. The mounting hole 421 can be a tapered hole or a stepped hole, which increases the thickness of the adhesive in the through hole and increases the stress strength of the sliding component 400.

[0135] refer to Figure 10 and Figure 11As shown, the sliding component 400 has four support positions 411, and the main body 420 has four mounting holes 421, which are evenly distributed around the outer periphery of the mounting center. That is, the main body 420 has multiple mounting holes 421, and the number of mounting holes 421 is the same as the number of support positions 411.

[0136] Regarding hinged components:

[0137] refer to Figure 15 As shown, the hinge component 700 includes a first hinge member 710 and a second hinge member (not shown in the figure). The first hinge member 710 is connected to the housing 100, and the second hinge member is connected to the door body 200. One of the first hinge member 710 and the second hinge member is provided with a hinge groove, and the other is provided with a shaft. (Reference) Figure 15 As shown, taking the first hinge member 710 with a hinge groove as an example, an adjusting member 720 is provided between the first hinge member 710 and the second hinge member. The adjusting member 720 is connected to the door body 200 and can rotate synchronously with the door body 200. The first hinge member 710 is provided with an adjusting protrusion 711, and the adjusting member 720 is provided with a first inclined surface 721 and a second inclined surface 722. The first inclined surface 721 is connected to the second inclined surface 722. The first inclined surface 721 is inclined upward towards the direction close to the second inclined surface 722, and the second inclined surface 722 is inclined upward towards the direction of the first inclined surface 721. During the opening and closing of the door, the adjusting protrusion 711 remains in contact with the first inclined surface 721 and the second inclined surface 722. As the first inclined surface 721 and the second inclined surface 722 rise and fall, the door body rises and falls accordingly.

[0138] During the closing process, when the first inclined surface 721 contacts the adjusting protrusion 711, the door body 200 descends and closes with the help of gravity as guided by the first inclined surface 721; during the opening process, when the second inclined surface 722 contacts the adjusting protrusion 711, the door body 200 descends and opens with the help of gravity as guided by the second inclined surface 722.

[0139] It should be noted that, Figure 15 The positional relationship between the first hinge 710 and the adjusting member 720 is shown for the convenience of illustrating the viewing angle of the first inclined surface, the second inclined surface, and the adjusting protrusion, and does not represent the installation state of the first hinge 710 and the adjusting member 720.

[0140] It should be noted that the structure of the hinge component 700 is not limited to... Figure 15 The structure shown can also have the first and second inclined surfaces set on the bottom surface of the hinge groove, or to provide assistance during the opening or closing of the door.

[0141] The other functions of the refrigeration equipment are described below.

[0142] It is understood that the door body 200 also includes a thickness adjustment component (not shown in the figure). The thickness adjustment component is located in the front-rear direction of the sliding component 400. For example, the thickness adjustment component is used to be located between the sliding component 400 and the cabinet panel 500, so as to adjust the relative position of the door body 200 and the cabinet panel 500 in the front-rear direction. Alternatively, the thickness adjustment component is located in the front-rear direction of the limiting component 300. For example, the thickness adjustment component is used to be located between the limiting component and the door body.

[0143] In some cases, the thickness adjustment component includes at least one shim. If multiple shims are used, their thicknesses can be the same or different, and the thickness direction of the shims is the front-to-back direction. By selecting shims of different thicknesses, the distance between the door body 200 and the cabinet panel 500 can be adjusted. The shims need to be provided with clearance holes to avoid the connection between the sliding component 400 and the cabinet panel 500. When the sliding component 400 is provided with mounting holes 421, the number of clearance holes is the same as the number of mounting holes 421, so as to avoid the first fastener 440 passing through the mounting hole 421; similarly, the clearance holes also avoid the installation position of the limiting component 300.

[0144] It should be noted that the outline shape of the gasket can be the same as the outline shape of the body part 420, that is, the gasket does not extend to the position corresponding to the support position 411, so as to avoid the gasket interfering with the limiting member 300.

[0145] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the scope of the claims of the invention.
