Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0066] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0068] Household appliances include dishwashers, refrigerators, freezers, and storage cabinets, which typically have shelves. Understandably, these appliances have inner shelves where items are stored. To retrieve an item, the shelf is pulled out of the inner shelf; after use, the shelf is pushed back into the inner shelf to store both the shelf and the item.

[0069] To facilitate user operation, a self-closing unit is often installed between the shelf and the inner liner. The self-closing unit uses its self-closing force to automatically pull the shelf back into the inner liner. During the process of pulling back into the inner liner, the shelf tends to continue moving after reaching the preset position due to inertia, which can easily cause the shelf to collide with the inner liner and cause damage.

[0070] In view of this, the present invention proposes a household appliance structure, which aims to improve the problem that the shelf in current household appliances is prone to collision with the inner liner, resulting in damage.

[0071] in, Figures 1 to 11 A schematic diagram of a partial structure of a household appliance structure provided by this utility model; Figures 12 to 13 Schematic diagrams of different states of the household appliance structure provided by this utility model.

[0072] Please see Figure 1 and Figure 2The household appliance structure 100 includes a shelf connector 1, a shelf assembly 2, a self-closing unit 3, and a stop structure 5. The shelf assembly 2 is movable relative to the shelf connector 1 in a first direction. The self-closing unit 3 includes a movable part 32 that can be movably installed in the first direction. The movable part 32 is provided on one of the shelf connector 1 and the shelf assembly 2, and a trigger part 4 is provided on the other. The stop structure 5 includes a stop block 51 and a mating post 52. One of the stop block 51 and the mating post 52 is provided on the shelf connector 1, and the other is provided on the shelf assembly 2. The trigger part 4 can engage with the movable part 32 so that the shelf assembly 2 moves relative to the shelf connector 1 under the drive of the movable part 32. The mating post 52 and the stop block 51 engage to prevent the shelf assembly 2 from moving toward the rear side wall of the receiving cavity 201 of the household appliance.

[0073] In the technical solution of this utility model, the self-priming unit 3 includes a movable part 32 that can be movably installed along a first direction. The movable part 32 is provided on one of the shelf connector 1 and the shelf assembly 2, and a trigger part 4 is provided on the other. Under the self-priming action of the self-priming unit 3, the shelf assembly 2 moves relative to the shelf connector 1 along the first direction. One of the stop block 51 and the mating post 52 is provided on the shelf connector 1, and the other is provided on the shelf assembly 2. The trigger part 4 can be combined with the movable part 32 so that the shelf assembly 2 moves relative to the shelf connector 1 under the drive of the movable part 32. The mating post 52 and the stop block 51 cooperate to stop the shelf assembly 2 from moving toward the rear side wall of the receiving cavity 201 of the household appliance. Under the joint stopping action of the stop block 51 and the mating post 52, the kinetic energy of the shelf assembly 2 is weakened, reducing the probability of the shelf assembly 2 being damaged due to collision.

[0074] It should be noted that in this utility model, the first direction can be a left-right direction, a top-bottom direction, or a front-back direction, etc. In some embodiments, the first direction is a front-back direction.

[0075] Using the user as a directional reference, forward is the direction toward the user, or the direction from the back of the household appliance toward the side of the household appliance with a door; backward is the opposite direction to forward, specifically the direction away from the user, or the direction from the side of the household appliance with a door toward the back of the household appliance; the up and down direction is the direction with gravity as a reference.

[0076] Please see Figures 11 to 13The household appliance structure 100 includes a housing 200, which forms a receiving cavity 201. The housing 200 exposes the entire external space of the household appliance, and an inner liner is provided inside the housing 200. The receiving cavity 201 is formed in the inner liner, and the shelf assembly 2 can be moved into or out of the receiving cavity 201.

[0077] The receiving cavity 201 has an opening on its front side, and a door is provided at the opening to close and open the opening. The shelf assembly 2 moves into and out of the receiving cavity 201 through the opening. The receiving cavity 201 has a rear sidewall corresponding to the opening, and the stop block 51 prevents the shelf assembly 2 from moving toward the rear sidewall to reduce collision between the shelf assembly 2 and the rear sidewall.

[0078] The shelf assembly 2 is mainly used to set up utensils to be placed, such as bowls, plates, dishes, chopsticks, knives and forks, as well as baked food or items to be refrigerated.

[0079] The shelf connector 1 is used to connect the housing 200 and the shelf assembly 2. Specifically, it is connected between the inner wall of the receiving cavity 201 and the shelf assembly 2 to enable the shelf assembly 2 to be moved into and out of the receiving cavity 201.

[0080] The mating post 52 and the stop block 51 cooperate to achieve the stopping function. It can be understood that when the mating post 52 and the stop block 51 stop and abut, there is still a distance between the shelf assembly 2 and the rear side wall of the receiving cavity 201, so as to reduce collision by preventing them from contacting each other.

[0081] One of the stop block 51 and the mating post 52 is located on the shelf connector 1, and the other is located on the shelf assembly 2. It can be understood that there are two possible arrangements: one is that the stop block 51 is located on the shelf connector 1 and the mating post 52 is located on the shelf assembly 2; the other is that the stop block 51 is located on the shelf assembly 2 and the mating post 52 is located on the shelf connector 1.

[0082] The connection between the stop block 51 and the shelf connector 1 or the shelf assembly 2 can be achieved by at least one of riveting, welding and threaded connection; the connection between the mating column 52 and the shelf connector 1 or the shelf assembly 2 can also be achieved by at least one of riveting, welding and threaded connection, which will not be described in detail above.

[0083] During the entire activity of the shelf assembly 2, the kinetic energy of the shelf assembly 2 can be converted into the internal energy between the mating column 52 and the stop block 51, or it can be dissipated in the form of internal energy and elastic potential energy to reduce the kinetic energy.

[0084] In some embodiments, please refer to Figure 3 and Figure 4 The shelf connector 1 includes a fixed slide rail 71. The shelf assembly 2 moves relative to the fixed slide rail 71 in a first direction. One of the stop block 51 and the mating post 52 is disposed on the fixed slide rail 71, and the other is disposed on the shelf assembly 2. In this configuration, the fixed slide rail 71 not only serves as the basis for the movement of the shelf assembly 2, but also as the basis for the placement of the stop block 51 and the mating post 52, which facilitates the placement of the stop block 51 and the mating post 52.

[0085] In some household appliances, such as refrigerators, freezers, or storage cabinets, the shelf assembly 2 only moves in the front-to-back direction, that is, it moves the shelf assembly 2 into or out of the inner liner's receiving cavity 201. In other household appliances, such as dishwashers, the shelf assembly 2 moves not only in the front-to-back direction but also in the up-and-down direction, so that the shelf assembly 2 can not only move into or out of the inner liner's receiving cavity 201, but also be raised to a suitable position after being moved out of the inner liner's receiving cavity 201, so as to reduce the user's bending over and facilitate the user's loading and unloading operations.

[0086] Specifically, in some embodiments, please refer to Figure 1 and Figure 3 The shelf connector 1 also includes a swing arm 302. One end of the swing arm 302 is rotatably mounted, and the other end of the swing arm 302 is connected to the fixed slide rail 71. That is, in the application scenario where the shelf assembly 2 not only moves in the front-back direction, but also moves in the up-down direction, one of the stop block 51 and the mating column 52 can be set on one of the swing arm 302 and the fixed slide rail 71. The setting method is more flexible and facilitates the setting of the stop block 51 and the mating column 52.

[0087] It should be noted that the fixed slide rail 71 is not fixedly installed relative to the receiving cavity 201. Instead, after the swing arm 302 swings to its limit position, the fixed slide rail 71 is fixed relative to the swing arm 302, that is, there is no relative movement between the fixed slide rail 71 and the swing arm 302.

[0088] The movable slide rail 72 is movable relative to the inner liner and also relative to the shelf connector 1. The movable slide rail 72 is fixedly installed relative to the first shelf 400.

[0089] When the stop block 51 is provided on the swing arm 302, the interference between the swing arm 302 and the fixed slide rail 71 during the movement of the swing arm 302 needs to be taken into account; when the stop block 51 is provided on the fixed slide rail 71, the interference between the fixed slide rail 71 and the shelf assembly 2 also needs to be taken into account.

[0090] When the mating post 52 is provided on the swing arm 302, the interference between the swing arm 302 and the fixed slide rail 71 during the movement of the swing arm 302 needs to be considered; when the mating post 52 extends in the left and right direction, the mating post 52 is welded or riveted to the swing arm 302; when the mating post 52 is provided on the fixed slide rail 71, the interference between the fixed slide rail 71 and the shelf assembly 2 also needs to be considered; when the mating post 52 extends in the left and right direction, the mating post 52 is welded or riveted to the fixed slide rail 71.

[0091] The shelf assembly 2 carries the items to be placed and is movable relative to the inner liner in the front-to-back direction. In some embodiments, please refer to... Figure 3 and Figure 4 The shelf connector 1 includes a fixed slide rail 71, and the shelf assembly 2 includes a first shelf 400 and a movable slide rail 72. The first shelf 400 and the movable slide rail 72 are fixedly connected, and the movable slide rail 72 slides relative to the fixed slide rail 71. One of the stop block 51 and the mating post 52 is disposed on the fixed slide rail 71, and the other is disposed on the movable slide rail 72. By distributing the stop block 51 and the mating post 52 on the fixed slide rail 71 and the movable slide rail 72 respectively, the stopping effect of the stop block 51 and the mating post 52 is directly applied between the fixed slide rail 71 and the movable slide rail 72, which can effectively avoid structural damage caused by uneven stress on the shelf assembly 2 as a whole, and improve the stability and durability of the entire household appliance structure 100. Meanwhile, when the movable slide rail 72 slides to a specific position relative to the fixed slide rail 71, the stop block 51 and the mating column 52 interact with each other, which can precisely limit the sliding range of the movable slide rail 72 and ensure the safety of the shelf assembly 2 during the forward and backward movement.

[0092] The first shelf 400 and the movable slide rail 72 can be fixedly connected by any one of bolt fixing, welding fixing, or snap-fit ​​fixing. For example, when bolt fixing is used, threaded holes can be made at corresponding positions of the first shelf 400 and the movable slide rail 72, and the two can be tightly connected together by bolts. This connection method is firm and reliable, and easy to disassemble and maintain. If welding fixing is used, the first shelf 400 and the movable slide rail 72 can be formed as a whole, with high connection strength, but disassembly is relatively difficult. When snap-fit ​​fixing is used, snaps and slots are respectively provided on the first shelf 400 and the movable slide rail 72. The quick connection and disassembly can be achieved by the cooperation of the snaps and slots, and the operation is simple.

[0093] When the stop block 51 is provided on the movable slide rail 72, the interference between the movable slide rail 72 and the fixed slide rail 71 during the movement process needs to be taken into account; when the stop block 51 is provided on the fixed slide rail 71, the interference between the fixed slide rail 71 and the first shelf 400 also needs to be taken into account.

[0094] In some embodiments, the mating post 52 is disposed on the fixed slide rail 71, and the stop block 51 is disposed in the port of the front end of the movable slide rail 72. This arrangement facilitates the installation of the stop block 51 and the mating post 52.

[0095] The mating column 52 is disposed on the fixed slide rail 71 in the manner described above, and can be at least one of riveting, welding and threaded connection.

[0096] In the configuration where the stop block 51 is located within the port of the front end of the movable slide rail 72, the movable slide rail 72 has an open structure, meaning that the sliding groove of the movable slide rail 72 extends from one end to the other. The stop block 51 can be located within the port of the front end of the movable slide rail 72, making installation simple and convenient.

[0097] In some embodiments, please refer to Figure 4 , Figure 5 and Figure 6 The stop block 51 is partially shaped to fit the port at the front end of the movable slide rail 72 so as to be better inserted into the port. The stop block 51 and the movable slide rail 72 are provided with a threaded connection structure to lock the stop block 51 onto the movable slide rail 72.

[0098] In addition, a limiting step is provided on the stop block 51. The limiting step abuts against the end of the movable slide rail 72. When installing the stop block 51, the abutment of the limiting step can quickly determine whether the stop block 51 is installed in place.

[0099] There are multiple ways to arrange and combine the trigger part 4, the self-priming unit 3, the stop block 51, and the mating post 52. Generally speaking, the trigger part 4 and the self-priming unit 3 are respectively disposed on the shelf connector 1 and the shelf assembly 2; the stop block 51 and the mating post 52 are respectively disposed on the shelf connector 1 and the shelf assembly 2. Therefore, there are several possible combinations, such as: the trigger part 4 and the stop block 51 are disposed on the shelf connector 1, and correspondingly, the self-priming unit 3 and the mating post 52 are disposed on the shelf assembly 2. The triggering part 4 and the mating post 52 are disposed on the shelf connector 1, and correspondingly, the self-priming unit 3 and the stop block 51 are disposed on the shelf assembly 2. The self-priming unit 3 and the stop block 51 are disposed on the shelf connector 1, and correspondingly, the triggering part 4 and the mating post 52 are disposed on the shelf assembly 2. The self-priming unit 3 and the mating post 52 are disposed on the shelf connector 1, and correspondingly, the triggering part 4 and the stop block 51 are disposed on the shelf assembly 2. All of the above are embodiments of the technical solution of this utility model.

[0100] In the embodiment where the shelf connector 1 includes a fixed slide rail 71, one of the self-closing unit 3 and the trigger part 4 is disposed on the fixed slide rail 71 and the other is disposed on the shelf assembly 2. This arrangement facilitates the placement of the self-closing unit 3 and the trigger part 4, and during the movement of the shelf assembly 2 relative to the fixed slide rail 71, the movable part 32 of the self-closing unit 3 can be well engaged with the trigger part 4.

[0101] One technical solution is that the self-priming unit 3 is disposed on the fixed slide rail 71, and the triggering part 4 is disposed on the shelf assembly 2; another technical solution is that the self-priming unit 3 is disposed on the shelf assembly 2, and the triggering part 4 is disposed on the fixed slide rail 71.

[0102] In some embodiments, please refer to Figure 7 and Figure 8 The self-priming unit 3 is mounted on the fixed slide rail 71 via a mounting member 6. The mounting member 6 includes a first connecting plate portion and a second connecting plate portion 61. The first connecting plate portion extends in the vertical direction to connect to the fixed slide rail 71; the second connecting plate portion 61 extends in the horizontal direction to connect to the self-priming unit 3.

[0103] The first connecting plate and the fixed slide rail 71 can be one of the following: threaded connection, snap-fit ​​connection, and welded connection.

[0104] The connection between the second connecting plate 61 and the self-priming unit 3 can also be one of the following: threaded connection, snap-fit ​​connection, and welded connection.

[0105] In some embodiments, please refer to Figure 9 and Figure 10 The self-priming unit 3 includes a mounting body 31, which is connected to the fixed slide rail 71 via the mounting member 6, and the movable part 32 is movably mounted on the mounting body 31 in the front-back direction.

[0106] A limiting groove 35 is provided on the mounting body 31, and the second connecting plate 61 is inserted into the limiting groove 35 to realize the installation of the self-priming unit 3 and the fixed slide rail 71.

[0107] To reduce the risk of detachment between the second connecting plate portion 61 and the limiting groove 35, in some embodiments, the groove sidewall of the limiting groove 35 is partially hollowed out to form a pressing spring buckle 36, which presses against the second connecting plate portion 61. The elastic pressing force of the pressing spring buckle 36 increases the static pressure of the second connecting plate portion 61, thereby increasing the static friction force that causes the second connecting plate portion 61 to detach outward, and greatly increasing the risk of detachment of the second connecting plate portion 61.

[0108] Please see Figure 1 In an embodiment where the trigger part 4 is located on the shelf assembly 2, to simplify the setting of the trigger part 4, the shelf assembly 2 further includes a connecting block 8 located between the first shelf 400 and the movable slide rail 72. The trigger part 4 and the connecting block 8 are connected as one unit, which improves their coordination during operation and enables more precise control of the movement of the first shelf 400, thereby enhancing the stability and reliability of the operation of the household appliance structure 100.

[0109] Specifically, the connecting block 8 and the trigger part 4 can be fixed together by means of snap-fit ​​connection, threaded connection, or welding connection. Different connection methods can be flexibly selected according to actual production needs and cost considerations. Snap-fit ​​connection is convenient to install and disassemble, making it suitable for scenarios requiring frequent disassembly or maintenance; threaded connection provides a more stable connection and can adapt to different usage requirements by adjusting the tightness of the threads; welding connection has the advantages of high connection strength and good sealing performance, making it suitable for household appliance structures 100 with high requirements for structural stability and sealing. In practical applications, appropriately selecting the connection method based on the specific structural design and usage environment can further improve the overall performance of the household appliance structure 100.

[0110] In some embodiments, the connecting block 8 and the trigger part 4 are integrally formed, eliminating additional connection processes, reducing the number of parts, simplifying the assembly process, lowering production costs, and preventing problems such as loosening and detachment due to weak connections. This further enhances the overall strength and stability of the household appliance structure 100. The integral forming design eliminates gaps between the connecting block 8 and the trigger part 4, reducing the possibility of dust, water stains, and other impurities entering the structure, improving its cleanliness and durability. This is particularly suitable for household appliances with high hygiene requirements, such as dishwashers. Simultaneously, the integral forming process ensures the dimensional accuracy and shape consistency of the connecting block 8 and the trigger part 4, making the household appliance structure 100 more stable and reliable during operation.

[0111] In embodiments where both the connecting block 8 and the trigger part 4 are made of rubber or plastic, both the connecting block 8 and the trigger part 4 can be integrally molded by injection molding.

[0112] The stop block 51 and the mating column 52 can be in direct contact to block, or they can be indirectly blocked through other intermediate structures, thereby effectively controlling the range of motion of the shelf assembly 2.

[0113] In some embodiments, please refer to Figure 4 , Figure 5 and Figure 6 The stop block 51 is provided with a locking groove 511 with an opening facing the mating post 52. The mating post 52 is located on the moving stroke of the stop block 51. During the movement of the first shelf 400 toward the cavity of the household appliance, the mating post 52 is inserted into the locking groove 511 to stop the movement of the rear side wall of the first shelf 400 toward the cavity of the household appliance. When the mating post 52 is inserted into the locking groove 511, the inner side wall of the locking groove 511 can play a certain guiding and positioning role for the mating post 52, so that the stopping effect of the stop block 51 and the mating post 52 is more stable and reliable, and the user experience is improved.

[0114] It should be noted that the engagement of the locking groove 511 and the mating post 52 can be either a full-stroke engagement relative to the travel of the movable part 32, whereby the locking groove 511 and the mating post 52 continuously act as a stop and buffer throughout the travel of the movable part 32; or a partial engagement engagement, whereby the locking groove 511 and the mating post 52 engage during a portion of the travel of the movable part 32, thereby causing the kinetic energy of the shelf assembly 2 to decay rapidly.

[0115] In some embodiments, the extension length of the locking groove 511 is less than the travel of the movable part 32. For the entire travel of the movable part 32, that is, at the front end of the travel of the movable part 32, the shelf assembly 2 can easily enter the receiving cavity 201 of the household appliance with less resistance; at the end of the travel of the movable part 32, the kinetic energy of the shelf assembly 2 decays rapidly, reducing the probability of the shelf assembly 2 being damaged due to collision.

[0116] It is understood that the locking groove 511 has an inlet and a groove rear wall corresponding to the inlet, and the extension length of the locking groove 511 is the distance length between the inlet and the groove rear wall. The travel of the movable part 32 is the size of one of the unidirectional travels in the reciprocating travel of the movable part 32.

[0117] At the opening of the locking groove 511, in order to facilitate the quick and smooth entry of the mating post 52 into the opening of the locking groove 511, in some embodiments, please refer to... Figure 4 , Figure 5 and Figure 6 The locking groove 511 has an inlet section 5111 at its opening. The width of the inlet section 5111 gradually decreases along the direction from the opening of the locking groove 511 towards its bottom, so that the width of the locking groove 511 is the largest at its opening. As it extends into the groove, the width gradually decreases, forming a flared structure that can play a good guiding role. When the mating post 52 approaches the opening, the larger entrance width makes it easier for the mating post 52 to be aligned and enter. The gradually decreasing groove width can constrain and guide the mating post 52 during the entry process, so that it moves smoothly into the groove, avoiding jamming or deviation, and improving the efficiency and stability of the entire structure assembly.

[0118] The mating post 52 and the stop block 51 cooperate to stop the relative movement between the shelf assembly 2 and the shelf connector 1. Under the joint stopping action of the stop block 51 and the mating post 52, the kinetic energy of the shelf assembly 2 is reduced, reducing the probability of damage to the shelf assembly 2 due to collision. In order to buffer the interaction between the mating post 52 and the stop block 51, in addition to converting the kinetic energy of the relative motion between the two into internal energy for dissipation, the kinetic energy of the relative motion between the two can also be converted into elastic potential energy to achieve buffering.

[0119] In some embodiments, the stop block 51 is at least partially deformable. This deformation absorbs some of the impact energy from the mating post 52, further reducing the likelihood of the shelf assembly 2 impacting the rear wall of the receiving cavity 201. This not only improves the stability of the household appliance structure 100 during use but also extends the appliance's lifespan. Simultaneously, the stop block 51, while limiting the mating post 52, also provides a certain degree of cushioning and shock absorption, enhancing the user experience.

[0120] Specifically, in an embodiment where the locking groove 511 is introduced to allow at least a portion of the stop block 51 to deform, the stop block 51 has a locking groove 511 with an opening facing the mating post 52, and the mating post 52 is located on the active stroke of the stop block 51. During the movement of the shelf assembly 2 toward the cavity of the household appliance, the groove sidewall of the locking groove 511 can deform to buffer the active insertion of the mating post 52. The groove sidewall of the locking groove 511 can not only dissipate energy through frictional movement relative to the mating post 52, but also deform to buffer the movement of the mating post 52, greatly reducing the kinetic energy of the relative movement between the mating post 52 and the locking groove 511.

[0121] Further, please refer to Figure 4 , Figure 5 and Figure 6 The inner wall of the locking groove 511 is provided with a retaining rib 512, so that the groove width of the locking groove 511 at the position corresponding to the retaining rib 512 is reduced, so that at least the retaining rib 512 deforms to buffer the active insertion of the mating post 52. The setting of the retaining rib 512 significantly increases the interference between the mating post 52 and the retaining rib 512 after the mating post 52 is inserted into the locking groove 511, so as to convert more kinetic energy of the mating post 52 and the stop block 51 into elastic potential energy, thereby further increasing the buffering effect during the movement of the shelf assembly 2.

[0122] The retaining rib 512 and the stop block 51 can be integrally formed, or they can be separately formed and then assembled into one. The cross-section of the retaining rib 512 can be triangular, circular, or square, etc.

[0123] In the width direction of the locking groove 511, along the inner wall of the locking groove 511 toward the middle position of the locking groove 511, the cross-sectional area of ​​the retaining rib 512 is gradually reduced, so that the interference between the mating post 52 and the retaining rib 512 gradually increases. This serves as a buffer and also facilitates the insertion of the mating post 52 into the side of the retaining rib 512 away from the opening of the locking groove 511.

[0124] Furthermore, in some embodiments, two retaining ribs 512 are provided, respectively disposed on two opposing inner groove walls of the locking groove 511. The mating post 52 is movably inserted between the two retaining ribs 512. The two retaining ribs 512 are arranged opposite each other, which can buffer and limit the mating post 52 from two directions, further enhancing the stability and buffering effect during the movement of the shelf assembly 2. Moreover, the spacing between the two retaining ribs 512 can be designed according to actual needs to ensure that the mating post 52 can be smoothly inserted while also achieving a good buffering interference effect. When the shelf assembly 2 moves, the mating post 52 moves between the two retaining ribs 512. The retaining ribs 512 absorb and disperse the kinetic energy of the mating post 52 through deformation, thereby effectively reducing the impact force generated by the movement of the shelf assembly 2.

[0125] It is understood that, along the extension direction of the locking groove 511, the two locking ribs 512 can be arranged opposite each other or staggered.

[0126] In embodiments where the stop block 51 is deformable, to further enhance the buffering effect, in some embodiments, the stop block 51 is partially hollowed out to form a buffer hole 513. Along the first direction, the buffer hole 513 is disposed opposite to the locking groove 511. Under the impact of the relative movement between the mating post 52 and the stop block 51, the two sidewalls of the buffer hole 513 along the front-rear direction can approach each other, thereby deforming to absorb and disperse the kinetic energy of the mating post 52, effectively improving the buffering capacity of the stop block 51 on the mating post 52.

[0127] It should be noted that the shape and size of the buffer hole 513 can be flexibly designed according to actual buffering needs, such as being designed as a long strip, circle, ellipse, or irregular shape. Different shapes will produce different deformation effects when the mating post 52 is impacted, thereby achieving different degrees of buffering effect. Furthermore, the number of buffer holes 513 is not limited to one; multiple buffer holes 513 can be provided as needed. The coordinated action of multiple buffer holes 513 can more comprehensively disperse the impact force of the mating post 52, further enhancing the buffering effect.

[0128] Along the vertical direction, the length of the buffer hole 513 is greater than the length of the locking groove 511, so that the middle position of the buffer hole 513 can completely cover the locking groove 511, thereby maximizing the deformation at the middle position of the buffer hole 513, improving the deformation capability of the portion of the buffer hole 513 corresponding to the locking groove 511, and further enhancing the buffering effect.

[0129] During the process of pushing the shelf assembly 2 from the outside into the receiving cavity 201 of the housing 200, the self-closing unit 3 acts as a self-closing unit, providing a pulling force to automatically pull the shelf assembly 2 inward. The self-closing unit 3 can be an elastic element 33 that generates the self-closing force, such as a spring or rubber elastomer, utilizing the elastic deformation of the elastic element 33 to generate a restoring force, thereby achieving the self-closing function; alternatively, it can be a magnetic attraction method, using corresponding magnetic elements on the shelf assembly 2 and the housing 200, utilizing the attraction between the magnetic elements to achieve self-closing, automatically pulling the shelf assembly 2 into the receiving cavity 201 of the housing 200. This self-closing unit 3 makes the pushing process of the shelf assembly 2 easier and more convenient, improving the user experience.

[0130] In some embodiments, please continue reading Figure 9 and Figure 10 The self-priming unit 3 further includes a mounting body 31. The movable part 32 is movable relative to the mounting body 31 along a first direction. An elastic element 33 is provided between the mounting body 31 and the movable part 32. During the movement stroke of the movable part 32, the elastic element 33 is always in a stretched state. One of the trigger part 4 and the mounting body 31 is located in the shelf connector 1, and the other is located in the shelf assembly 2. Driven by the elastic restoring force of the elastic element 33, the movable part 32 is movably mounted on the mounting body 31 along the first direction. The elastic restoring force of the elastic element 33 causes the shelf assembly 2 to automatically move towards the inner liner of the housing 200. The structure is simple, making the movement of the shelf assembly 2 more stable.

[0131] During the movement of the movable part 32 in the front-to-back direction, when the movable part 32 moves to the position where it contacts the trigger part 4, the trigger part 4 and the movable part 32 engage to synchronously drive the shelf assembly 2 to move. By reasonably setting the elastic coefficient of the elastic element 33 and the range of motion of the movable part 32, the triggering timing and triggering force of the trigger part 4 can be precisely controlled, thereby ensuring the stability and reliability of the entire household appliance structure 100.

[0132] It is understood that the elastic element 33 is always in a stretched state, that is, the elastic element 33 stores energy throughout the entire stroke of the movable part 32. When the trigger part 4 and the movable part 32 are not in contact, the deformation of the elastic element 33 is large. After the trigger part 4 and the movable part 32 come into contact, as the movable part 32 gradually moves, the deformation of the elastic element 33 gradually decreases to gradually release the elastic potential energy. When the user pulls the shelf assembly 2 from the inside to the outside, the deformation of the elastic element 33 gradually increases to store the elastic potential energy.

[0133] Throughout the entire stroke of the movable part 32, the trigger part 4 and the movable part 32 need to be engaged and disengaged. When engaged, the movement of the shelf assembly 2 and the movable part 32 is synchronized, so that the shelf assembly 2 automatically moves toward the inner liner of the housing 200 under the drive of the movable part 32; when disengaged, the movement of the shelf assembly 2 and the movable part 32 separates, so that the shelf assembly 2 can move to other positions relative to the fixed slide rail 71 or the swing arm 302.

[0134] The switching between the engagement and disengagement of the trigger part 4 and the movable part 32 can be achieved by partial deformation of the mounting body 31. For example, the movable part 32 can be made of a deformable material (such as rubber or plastic) so that the trigger part 4 can be installed with the movable part 32.

[0135] In some embodiments, the front end of the mounting body 31 is provided with a receiving groove 311, and the movable part 32 includes a sliding piece 321 and a sliding buckle 322. The sliding piece 321 is movably mounted on the mounting body 31 along a first direction. The elastic member 33 is connected between the sliding piece 321 and the mounting body 31. The sliding buckle 322 is rotatably connected to the sliding piece 321. The sliding piece 321 drives the sliding buckle 322 to move along the first direction and can rotate to be received in the receiving groove 311, so that the sliding buckle 322 and the trigger part 4 are separated. With this configuration, the movement mode of the movable part 32 can be decomposed into two types: one is linear movement along the front-back direction, and the other is rotational connection. The rotational connection allows the sliding buckle 322 to avoid the trigger part 4 and separate from the trigger part 4, and also allows the sliding buckle 322 and the trigger part 4 to engage.

[0136] When the sliding buckle 322 rotates to the position corresponding to the trigger part 4, the sliding buckle 322 can move along the first direction under the drive of the sliding piece 321 to engage with the trigger part 4. At this time, the shelf assembly 2 can automatically move into the inner liner of the housing 200 under the drive of the movable part 32. Furthermore, by providing the receiving groove 311, a dedicated receiving space is provided for the sliding buckle 322. When it is necessary for the sliding buckle 322 and the trigger part 4 to separate, the sliding buckle 322 can be stably accommodated therein, ensuring the stability and reliability of the structure operation.

[0137] The sliding buckle 322 and the trigger part 4 can be joined by magnetic attraction or by a convex-concave fit. In some embodiments, the sliding buckle 322 has a mating groove 3221 with its opening facing left and right. The trigger part 4 has a trigger protrusion 41. The mating groove 3221 and the trigger protrusion 41 are positioned opposite each other in the left and right direction. The trigger protrusion 41 can be inserted into the mating groove 3221 to allow the sliding buckle 322 and the trigger part 4 to engage. The precise engagement of the trigger protrusion 41 with the mating groove 3221 not only achieves a stable connection between the sliding buckle 322 and the trigger part 4 but also ensures the accuracy and reliability of their engagement. This convex-concave fit is simple yet highly effective, capable of withstanding certain external forces and preventing accidental separation during use.

[0138] To guide the movement of the movable part 32 in the front-back direction, in some embodiments, a guide rib 34 extending in a first direction is provided between the slider 321 and the mounting body 31. The guide rib 34 can provide precise guidance for the movement of the slider 321 relative to the mounting body 31, ensuring that the slider 321 drives the sliding buckle 322 to move stably in the first direction, thereby ensuring that the movable part 32 moves accurately in the predetermined front-back direction, avoiding deviation or shaking, and improving the stability and accuracy of the operation of the entire household appliance structure 100.

[0139] This utility model also proposes a dishwasher, which adopts all the technical solutions of all the above embodiments, and therefore has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0140] Inside the dishwasher, please refer to Figure 12 and Figure 13 A second shelf 500 is also provided in the receiving cavity 201 of the housing 200. After the first shelf 400 is stored in the receiving cavity 201 of the housing 200, the second shelf 500 is above the first shelf 400. After the first shelf 400 moves upward to the top position, the first shelf 400 is in front of the second shelf 500.

[0141] Alternatively, the connection structure between the second shelf 500 and the inner liner can also adopt the above-mentioned configuration of fixed slide rail 71, movable slide rail 72, mating column 52 and stop block 51.

[0142] The following describes the user's experience using a household appliance (dishwasher) based on its structure, with the first shelf (400) as a reference:

[0143] 1. The first shelf 400 is in its initial bottom position, such as... Figure 12 As shown:

[0144] This state indicates that the user is not using the appliance, has just started using it, or has finished using it. In these states, the first shelf 400 is located within the receiving cavity 201 of the household appliance. Figure 12 As can be seen, the first shelf 400 is retracted into the receiving cavity 201; at this time, the fixed slide rail 71 and the movable slide rail 72 move relative to each other to the minimum stroke position. At this time, the trigger part 4 and the sliding buckle 322 of the movable part 32 are engaged. The mating post 52 provided on the fixed slide rail 71 and the locking groove 511 of the stop block 51 provided on the movable slide rail 72 are engaged. The stop block 51 is used to prevent the first shelf 400 from continuing to move backward after moving to the preset position and hitting the inner liner of the household appliance.

[0145] 2. The first shelf 400 is in the bottom position to be lifted, such as... Figure 13 As shown:

[0146] This state refers to the user pulling out the first shelf 400 from the receiving cavity 201, or the user lowering the first shelf 400 after using it. In these states, the first shelf 400 is at the opening of the receiving cavity 201. At this time, the fixed slide rail 71 and the movable slide rail 72 move relative to each other to their maximum stroke. At this time, the sliding buckle 322 of the trigger part 4 and the movable part 32 separates, and the locking groove 511 of the mating post 52 provided on the fixed slide rail 71 and the stop block 51 provided on the movable slide rail 72 separates.

[0147] The following will describe a complete user experience flow, based on the above embodiments:

[0148] When a user needs to use a household appliance, they first open the appliance's door. The user then pulls the first shelf 400 forward from the bottom initial position out of the receiving cavity 201 to the bottom lifting position. Combined with the swinging action of the swing arm 302, the user continues to pull the first shelf 400 forward and upward, causing it to move from the bottom lifting position to the top lifting limit position. The user continues to pull the first shelf 400 forward, causing it to move from the top lifting limit position to the top locking position. In the locked state, the user can retrieve and place items within the first shelf 400 with reduced bending frequency.

[0149] When the user finishes retrieving or placing the item, the user pushes the first shelf 400 backward to unlock it and move it from the top unlocked position to the top raised limit position. The user then lowers the first shelf 400, moving it from the top raised limit position to the bottom ready-to-raise position. The user continues to push the first shelf 400 backward, moving it from the bottom ready-to-raise position to the bottom initial position. When the first shelf 400 is in the bottom initial position, the user can close the door to complete the use of the household appliance.

[0150] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
