[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] The terms used in this document, such as “center,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” indicating spatial relative positions, are used for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative positions” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0030] For example, if the device in the figure is flipped, a unit described as being "below" or "under" other units or features will be "above" other units or features. Therefore, the exemplary term "below" can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or otherwise), and the spatially related descriptive terms used herein will be interpreted accordingly.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] Furthermore, it should be understood that although the terms "first," "second," etc., may be used herein to describe various elements or structures, the objects being described should not be limited by these terms. These terms are only used to distinguish these objects from one another. For example, a first fixing part may be referred to as a second fixing part, and similarly, a second fixing part may be referred to as a first fixing part, without departing from the scope of protection of this application.

[0033] This application provides a door assembly that can be used in embedded refrigeration equipment, and the door assembly is connected to the housing 10 of the refrigeration equipment 100. In addition, it can also be used in other embedded home appliances.

[0034] like Figure 2 , 3As shown, the aforementioned door assembly has a door body 1 and a decorative panel 2 disposed on the front side of the door body 1. The door body 1 includes a door shell 11 with an insulation cavity and a fixing mechanism disposed on the door shell 11. The door shell 11 integrally forms a recessed portion 111 that is recessed towards the insulation cavity. A clearance cavity 112 is formed on the side of the recessed portion 111 that is away from the insulation cavity. The clearance cavity 112 is opened towards the decorative panel 2. The fixing mechanism is fixed at the clearance cavity 112. A fitting member 5 is disposed on the side of the decorative panel 2 facing the door body 1. The fitting member 5 is connected to the fixing mechanism.

[0035] The door shell 11 is integrally formed into a recessed portion 111, and a fixing mechanism is provided at the relief cavity 112 formed in the recessed portion 111 for connection with the mating part 5 on the decorative panel 2. This avoids the need to open holes in the door shell 11 for setting the embedded box and completely avoids the overflow of the foaming material in the insulation cavity.

[0036] In one embodiment of this application, the fixing mechanism includes a fixing member 3 fixed to the recess 111. The fixing member 3 forms a receiving cavity 31 that opens toward the decorative panel 2. The fixing mechanism also includes a connecting structure disposed at the receiving cavity 31. The mating member 5 extends into the receiving cavity 31 and is mated and connected with the connecting structure.

[0037] The mating part 5 extends into the receiving cavity 31 and mates with the connecting structure, which can prevent the mating part 5 and the connecting structure from being located between the door body 1 and the decorative panel 2, resulting in a large gap between them.

[0038] In one embodiment of this application, a fixing hole (not shown) is provided on the side opposite to the opening of the recessed portion 111 and the relief cavity 112. A fixing groove is provided at the rear end of the fixing member 3 corresponding to the fixing hole. The fixing member 3 is fixed to the recessed portion 111 by the cooperation of the fixing hole and the fixing groove.

[0039] Screws or other fasteners are passed through the fixing holes and into the fixing grooves to fix the fixing member 3 to the recess 111. Although there are still fixing holes for fixing in the recess 111 of the door shell 11, the area of ​​the fixing hole is much smaller than the opening for the pre-embedded box to be exposed, and it is completely covered by the fixing member 3, so there will be no overflow problem.

[0040] Of course, adhesives such as glue can also be used to fix the fastener 3 to the recess 111.

[0041] In one embodiment of this application, the recess 111 is provided on the edge of the door shell 11; the clearance cavity 112 also opens toward the side.

[0042] The edge of the door shell 11 has high strength, while the middle part has weak strength due to the lack of supporting structure. The fastener 3 that fixes the recessed part 111 needs to be connected to the mating part 5 on the decorative panel 2. The recessed part 111 is set on the edge with high strength to provide high strength for the fastener 3 and avoid damage to the recessed part 111 under force.

[0043] The recessed cavity 112 also opens to the side, which reduces the difficulty of molding and demolding the door shell 11 and avoids the problem of small gaps between the recessed part 111 and the side of the door shell 11, which makes foaming more difficult.

[0044] In one embodiment of this application, the connecting structure includes a hook member 4, which forms a hook hole 411, and a mating member 5 extends from the hook hole 411 into the receiving cavity 31 to mate with the hook member 4.

[0045] The mounting member 4 forms a mounting hole 411, allowing the mating member 5 to enter the receiving cavity 31 through the mounting hole 411, thus avoiding a large gap between the door body 1 and the decorative panel 2. After the mating member 5 extends into the receiving cavity 31, it engages with the part of the mounting member 4 located around the mounting hole 411.

[0046] The mating component 5 may include a hook 51, which is hung on the edge of the hanging hole 411; the mating component 5 also includes a first fixing part 52 and a connecting part 53 that connects the hook 51 and the first fixing part 52. In the front-back direction, the length of the connecting part 53 is equal to the thickness of the hanging component 4 at the position around the hanging hole 411.

[0047] The length of the connecting part 53 is equal to the distance between the hook 51 extending into the hanging hole 411 and the first fixing part 52 fixed to the decorative panel 2. This distance is equal to the thickness of the hanging part 4 around the hanging hole 411, so that the mating part 5 and the hanging part 4 are fixed in the front-back direction after they are mated, thus preventing the decorative panel 2 from shaking in the front-back direction.

[0048] Of course, in actual production and use, the length of the connecting part 53 may have an error that is slightly greater than the thickness of the hanging parts 4 around the hanging hole 411 (e.g., 0.1mm), in order to facilitate actual installation.

[0049] The mating part 5 may also include other structures that can mate with the hook that passes through the hook hole 411 and engage with the hook, such as a hook (similar to an arrow shape) with a gradually decreasing cross section in the direction from front to back, which can be inserted into the hook hole 411 from front to back and stop by using the edge of the hook hole 411 toward the receiving cavity 31 to prevent the hook from coming out of the hook hole 411.

[0050] In one embodiment of this application, the abutment 4 is disposed at the opening of the receiving cavity 31 and fixed to the fixing member 3. For example... Figure 4 In the middle, the hanging part 4 is a sheet-like structure that covers and fixes the opening of the receiving cavity 31, and has a hanging hole 411.

[0051] In one embodiment of this application, the shape and size of the hanging member 4 are matched with the opening of the receiving cavity 31, the fixing member 3 is provided with a second fixing part 3111 located in the receiving cavity 31, the hanging member 4 is fixed to the second fixing part 3111, and the distance between the second fixing part 3111 and the opening of the receiving cavity 31 is matched with the thickness of the hanging member 4.

[0052] like Figure 4 In the middle, there are two second fixing parts 3111. The two second fixing parts 3111 are set at the top and bottom of the receiving cavity 31 along the height direction of the door body 1 (the length of the receiving cavity 31 in the height direction of the door body 1 is greater than the length in the width direction of the door body 1, that is, the two second fixing parts 3111 are actually set at both ends of the receiving cavity 31). The distance between the second fixing part 3111 and the opening of the receiving cavity 31 is matched with the thickness of the second fixing part 3111 so that the hanging part 4 is just set at the opening of the receiving cavity 31.

[0053] In another embodiment of this application, such as Figure 5 In the connection structure, there is also a reinforcing member 46, which is fixed to the hanging member 4 and abuts against one side of the hanging hole 411, and a mating hole 461 is provided corresponding to the hanging hole 411.

[0054] After the mating part 5 extends into the receiving cavity 31 from the hanging hole 411, it needs to mate with the edge of the hanging hole 411. The mating hole 461 is consistent with the hole shape and size of the hanging hole 411. The reinforcing part 46 is fixed to the hanging part 4 and abuts against the hanging hole 411 to strengthen the structural strength of the edge of the hanging hole 411.

[0055] The mounting part 4 can be made of plastic, and the reinforcing part 46 can be made of sheet metal. Of course, if the mounting part 4 can also be made of sheet metal and its strength is sufficient, the reinforcing part 46 may not be required.

[0056] In one embodiment of this application, the attachment 4 is fixed to the fixing member 3 by a snap fastener 3121.

[0057] like Figure 5 In this assembly, the mounting member 4 includes a front plate 41 and four side plates 42 connected to the front plate 41. The front plate 41 has the aforementioned mounting holes 411, and the side plates 42 are provided with snap-fit ​​holes 421 (or snap-fit ​​grooves). The fixing member 3 includes a bottom wall 311 forming the perimeter of the receiving cavity 31 and four side walls 312, with snap fasteners 3121 provided on the side walls 312. The mounting member 4 extends into the receiving cavity 31 from the end of the side plate 42 away from the front plate 41 and is fixed to the fixing member 3 with the cooperation of the snap-fit ​​holes 421 and snap fasteners 3121.

[0058] If the strength of the hanging part 4 is sufficient, the reinforcing part 46 may not be required. If the strength of the hanging part 4 is insufficient, the reinforcing part 46 shall be placed on the side of the front plate 41 connected to the side plate 42 before the hanging part 4 enters the receiving cavity 31. In other words, the reinforcing part 46 shall be placed in the space formed by the front plate 41 and the four side plates 42 and shall be attached to the front plate 41. Then the hanging part 4 shall be snapped onto the fixing part 3.

[0059] In one embodiment of this application, the attachment 4 is movably connected to the fixing member 3, and the direction of movement has at least a front-back component.

[0060] The fastener 3 is fixed to the recess 111 of the door shell 11. The hook 4 has a forward and backward component relative to the fastener 3, which can drive the decorative panel 2 to move forward and backward relative to the door body 1 to adjust the front and back gap between the decorative panel 2 and the door body 1.

[0061] In some embodiments, since the hook 4 can move back and forth relative to the fixing member 3, the door assembly further includes a locking structure that locks the moving position of the hook 4 so that when the decorative panel 2 moves to a suitable position relative to the door 1 in the back and forth direction, the relative position of the two can be locked.

[0062] In some embodiments, the locking structure includes a mounting hole 422, a connecting hole 33, and a connector 47.

[0063] Among them, such as Figure 3 In the middle, the hanging component 4 includes a front plate 41 with a hanging hole 411 and a side plate 42 connected to the front plate 41, and a mounting hole 422 is opened in the side plate 42; the connecting hole 33 is set in the fixing component 3 corresponding to the mounting hole 422; in the front-back direction, the length of the connecting hole 33 is greater than the length of the mounting hole 422; the connecting component 47 passes through the connecting hole 33 and the mounting hole 422 to fix the hanging component 4 to the fixing component 3.

[0064] During installation, first pass the connector 47 through the connecting hole 33 and the mounting hole 422 in sequence. After the mating part 5 on the decorative panel 2 mates with the hanging part 4, move the decorative panel 2 back and forth. The mating part 5 drives the hanging part 4 to move back and forth, and the hanging part 4 drives the connector 47 to move back and forth in the connecting hole 33. After the decorative panel 2 is adjusted back and forth, lock the connector 47 to complete the installation and adjustment. The connector 47 can be a screw or other fastener.

[0065] As the hanging component 4 is movably connected to the fixed component 3, in addition to the locking structure, a driving mechanism can also be provided. The driving mechanism is connected to the hanging component 4 and drives the hanging component 4 to move. When the driving mechanism drives the hanging component 4 to move to the decorative panel 2 and then stops driving, the hanging component 4 stops moving, and the decorative panel 2 also stops moving.

[0066] In this embodiment, the left (or right) sidewall 312 of the receiving cavity 31 is formed as a first inclined surface 3122, and the hook member 4 is correspondingly disposed on the second inclined surface 43 that cooperates with the first inclined surface 3122. By adjusting the movement of the hook member 4 in the width direction, the hook member 4 can also move in the front-back direction under the cooperation of the first inclined surface 3122 and the second inclined surface 43.

[0067] Specifically, such as Figure 7 In the process, the attachment 4 is provided with a travel groove 44 extending in the width direction. The travel groove 44 is provided with a thread. The thread can be directly machined into the travel groove 44 of the attachment 4, or a nut or other component with internal thread can be fixed into the travel groove 44.

[0068] The drive mechanism includes an adjusting rod 61, which has external threads. The adjusting rod 61 passes through the connecting hole 33 on the fixing member 3 and extends into the stroke groove 44, where it is threadedly connected to the threads in the stroke groove 44.

[0069] The adjusting rod 61 extends out of the receiving cavity 31, and the end of the rod extending out of the receiving cavity 31 is set as a head 611, the size of which is larger than the connecting hole 33.

[0070] The rotation of the adjusting rod 61 causes its head 611 to move closer to the abutment 4. With the stop of the fixing part 3 and the head 611 of the adjusting rod 61, the head 611 of the adjusting rod 61 cannot actively move closer to the abutment 4. Instead, the abutment 4 moves towards the head 611 of the adjusting rod 61. Thus, with the cooperation of the first inclined surface 3122 and the second inclined surface 43, the abutment 4 has the ability to move in the front and back direction.

[0071] like Figure 7 As shown, the first inclined surface 3122 and the second inclined surface 43 extend from front to back toward the head 611 of the adjusting rod 61. When the adjusting rod 61 rotates and drives the hook 4 to move toward the head 611, the hook moves backward (decorative panel 2 → door body 1) at the same time, thereby driving the decorative panel 2 closer to the door body 1.

[0072] When the adjusting rod 61 rotates in the opposite direction, the head 611 of the adjusting rod 61 loses the obstruction of the side of the fixing member 3 and moves away from the hanging member 4, so that the decorative panel 2 can be moved forward. With the cooperation of the first inclined surface 3122 and the second inclined surface 43, the hanging member 4 also moves away from the head 611 until the head 611 abuts against the side of the fixing member 3 again.

[0073] Since the adjusting rod 61 moves together with the hanging part 4, the connecting hole 33 on the fixing part 3 is an elongated hole extending in the front-back direction, and its length is greater than the outer diameter of the adjusting rod 61.

[0074] In this embodiment, the fixing member 3 is provided with a guide rail 3123 along the top and / or bottom of the first inclined surface 3122, and the hanging member 4 is provided with a slide rail 431 corresponding to the guide rail 3123. The slide rail 431 and the guide rail 3123 cooperate to make the second inclined surface 43 unable to separate from the first inclined surface 3122 in the width direction, that is, the second inclined surface 43 can only move in contact with the first inclined surface 3122.

[0075] Since the opening panel of the receiving cavity 31 of the fastener 3 is small, while the bottom area away from the decorative panel 2 is large, in this embodiment, the outer edge of the cross-sectional view of the hanging member 4 cut along the horizontal plane is a parallelogram, so that the hanging member 4 can be tilted and pushed into the receiving cavity 31 along the first inclined surface 3122.

[0076] In this embodiment, a locking groove 612 is provided at the end of the adjusting rod 61 away from the head 611. A stop ring 62 is provided in the locking groove 612. Since the stop ring 62 abuts against the end of the stroke groove 44, it prevents the adjusting rod 61 from disengaging from the stroke groove 44. Of course, if the adjusting rod 61 is long enough, the locking groove 612 and the stop ring 62 may not be provided.

[0077] As another implementation of this embodiment, the movement of the adjusting rod 61 in its length direction is restricted, so that the adjusting rod 61 can only rotate relative to the door body 1.

[0078] During rotation, under the action of the thread, the hanging part 4 can move towards or away from the head 611 in the direction of rotation of the adjusting rod 61, thereby moving the decorative panel 2 backward or forward with the cooperation of the first inclined surface 3122 and the second inclined surface 43, without having to manually pull the decorative panel 2 forward for adjustment.

[0079] Specifically, a stop groove 34 communicating with the connection hole 33 is provided at the position of the connection hole 33 in the fixing member 3, and the aforementioned locking groove 612 is set in the stop groove 34. The inner edge of the stop ring 62 is fixed in the locking groove 612, and the outer edge is limited in the stop groove 34. The distance between the head 611 and the stop ring 62 is equal to the distance between the stop groove 34 and the side of the fixing member 3, so that the adjusting rod 61 cannot be displaced in its length direction.

[0080] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0081] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this application and are not intended to limit the scope of protection of this application. All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this application.
