Description

Technical Field

[0001] This utility model relates to the field of household appliance structure technology, and in particular to a household appliance structure and a dishwasher. Background Technology

[0002] 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.

[0003] 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. Utility Model Content

[0004] To solve the above-mentioned technical problems, a damping component is often installed between the shelf and the inner liner to allow the shelf to perform damped movement during the process of being pulled back into the inner liner. However, how to install and set the damping component is a problem that urgently needs to be solved.

[0005] To achieve the above objectives, this utility model proposes a household appliance structure, comprising:

[0006] The shell has a receiving cavity;

[0007] The shelf assembly is capable of moving back and forth relative to the housing; and,

[0008] A damping assembly includes a damping structure and a triggering part. The damping structure includes a mounting body and a movable part. The mounting body is disposed on the receiving cavity. The movable part can reciprocate back and forth relative to the mounting body. The triggering part is disposed on the shelf assembly. During the process of the shelf assembly moving from front to back relative to the receiving cavity, the triggering part can engage with the movable part to dampen the movement of the shelf assembly toward the receiving cavity.

[0009] In one embodiment, the damping structure further includes a self-closing unit, which includes a first elastic member disposed between the movable part and the mounting body. During the forward and backward movement of the movable part, the first elastic member is always in a stretched state, so that the movable part moves back under the elastic restoring force of the first elastic member, thereby driving the shelf assembly to move towards the receiving cavity.

[0010] In one embodiment, the front end of the mounting body is recessed to form a receiving groove;

[0011] The movable part includes a slide plate, which is movably mounted relative to the mounting body, and the first elastic element is connected between the slide plate and the mounting body;

[0012] The slider can be at least partially accommodated within the accommodating groove, so that the trigger part and the slider are separated; the slider can be moved out of the accommodating groove, so that the trigger part and the slider are engaged.

[0013] In one embodiment, the slider includes a main body and a sliding buckle rotatably mounted on the main body along an axis extending in the vertical direction. The sliding buckle is provided with a receiving slot for the trigger part to be inserted and engaged.

[0014] When the sliding buckle rotates in the forward direction, it can avoid being accommodated in the receiving groove, and the trigger part disengages from the receiving slot, so that the sliding buckle and the trigger part are separated; when the sliding buckle rotates in the reverse direction, it can move out of the receiving groove, and the trigger part is inserted into the receiving slot, so that the sliding buckle and the trigger part are engaged.

[0015] In one embodiment, the damping structure further includes a buffer unit connected to the movable part for damping the movement of the shelf assembly toward the receiving cavity.

[0016] In one embodiment, the buffer unit includes a buffer cylinder and a connecting rod telescopically connected to the buffer cylinder;

[0017] The connecting rod is connected to the movable part, and the buffer cylinder is fixedly installed on the mounting body.

[0018] In one embodiment, the buffer unit includes a second elastic element connected to the movable part and the mounting body, wherein the second elastic element is always in a compressed state during the movement stroke of the movable part;

[0019] During the movement of the movable part from front to back, the compression of the second elastic element gradually increases to buffer the movement of the movable part.

[0020] In one embodiment, the household appliance structure further includes a mounting member connected to the inner wall of the receiving cavity, the mounting member having a plug-in plate portion extending in the left-right direction;

[0021] A limiting groove is provided on the mounting body, and the plug-in plate is inserted into the limiting groove.

[0022] In one embodiment, the housing includes an inner liner, and the receiving cavity is formed in the inner liner;

[0023] The shelf assembly includes a first shelf, and the mounting member is connected to the side wall of the inner liner and disposed below the first shelf.

[0024] In one embodiment, the household appliance structure further includes a fixed slide rail and a movable slide rail that is slidably mounted relative to the fixed slide rail in the front-back direction;

[0025] The shelf assembly includes a first shelf connected to the movable slide rail;

[0026] The triggering part is located on the movable slide rail or the first shelf.

[0027] In one embodiment, the household appliance structure further includes a swing arm, one end of which is hinged to the receiving cavity, and the other end of which is hinged to the fixed slide rail;

[0028] The swinging motion of the swing arm causes the first shelf to switch between a low position and a high position. Corresponding to the low position, the fixed slide rail and the movable slide rail move relative to each other, so that the first shelf has an initial bottom position that is entirely inside the receiving cavity and a bottom position that is at least partially outside the receiving cavity and is ready to be lifted.

[0029] During the process of the first shelf moving from the bottom to the initial bottom position, the damping component is used to dampen the movement of the first shelf into the receiving cavity.

[0030] This utility model also proposes a dishwasher, including a household appliance structure, the household appliance structure comprising:

[0031] The shell has a receiving cavity;

[0032] The shelf assembly is capable of moving back and forth relative to the housing; and,

[0033] A damping assembly includes a damping structure and a triggering part. The damping structure includes a mounting body and a movable part. The mounting body is disposed on the receiving cavity. The movable part can reciprocate back and forth relative to the mounting body. The triggering part is disposed on the shelf assembly. During the process of the shelf assembly moving from front to back relative to the receiving cavity, the triggering part can engage with the movable part to dampen the movement of the shelf assembly toward the receiving cavity.

[0034] In the technical solution of this utility model, the damping component includes a damping structure and a triggering part. The damping structure includes a mounting body and a movable part. The mounting body is disposed on the receiving cavity, and the movable part can reciprocate back and forth relative to the mounting body. The triggering part is disposed on the shelf assembly.

[0060] Household appliance structure 100 includes dishwashers, refrigerators, freezers, or storage cabinets, which are typically equipped with shelves. Understandably, some household appliances have an inner liner 12, and the shelves store items to be stored. When there is a need to retrieve an item, the shelf needs to be pulled out of the inner liner 12; after use, the shelf needs to be pushed back into the inner liner 12 to store the shelf and the retrieved item.

[0061] During the process of pulling back into the inner liner 12, the shelf tends to continue moving after reaching the preset position due to inertia, which may cause the shelf to collide with the inner liner 12 and cause damage.

[0062] To solve the above-mentioned technical problems, a damping component 3 is often installed between the shelf and the inner liner 12 so that the shelf can perform damping activity when it is pulled back to the inner liner 12. However, how to install and set the damping component 3 is a problem that needs to be solved.

[0063] in, Figures 1 to 9 A schematic diagram of one embodiment of the household appliance structure 100 provided by this utility model; Figures 10 to 12 Schematic diagrams of different states of the household appliance structure 100 provided by this utility model.

[0064] Please see Figures 1 to 4The household appliance structure 100 includes a housing 1, a shelf assembly 2, and a damping assembly 3. The housing 1 forms a receiving cavity 11. The shelf assembly 2 is capable of moving back and forth relative to the housing 1. The damping assembly 3 includes a damping structure 31 and a triggering part 32. The damping structure 31 includes a mounting body 311 and a movable part 312. The mounting body 311 is disposed on the receiving cavity 11. The movable part 312 is capable of reciprocating back and forth relative to the mounting body 311. The triggering part 32 is disposed on the shelf assembly 2. During the process of the shelf assembly 2 moving from front to back relative to the receiving cavity 11, the triggering part 32 can engage with the movable part 312 to dampen the movement of the shelf assembly 2 toward the receiving cavity 11.

[0065] In the technical solution of this utility model, the damping component 3 includes a damping structure 31 and a triggering part 32. The damping structure 31 includes a mounting body 311 and a movable part 312. The mounting body 311 is disposed on the receiving cavity 11. The movable part 312 can reciprocate back and forth relative to the mounting body 311. The triggering part 32 is disposed on the shelf assembly 2. During the process of the shelf assembly 2 moving from front to back relative to the receiving cavity 11, the triggering part 32 can engage with the movable part 312 to dampen the movement of the shelf assembly 2 toward the receiving cavity 11. The damping structure 31 is disposed on the inner wall of the receiving cavity 11, which makes the installation very simple, saves the installation space of other structures, facilitates the relative movement between the structures, and improves the user experience.

[0066] It should be noted that in this utility model, the user is used as the direction reference. Forward is the direction towards the user, or the direction from the back of the household appliance towards the side of the household appliance with the door; backward is the direction opposite to forward, specifically the direction away from the user, or the direction from the side of the household appliance with the door towards the back of the household appliance; the up and down direction is the direction with gravity as the reference.

[0067] Please see Figure 1 , Figure 3 and Figure 9 The household appliance structure 100 includes a housing 1, with an inner liner 12 formed therein, and a receiving cavity 11 inside the inner liner 12. The housing 1 shows the overall external space of the household appliance, with the inner liner 12 disposed inside the housing 1, and the receiving cavity 11 formed therein. The shelf assembly 2 can be moved into or out of the receiving cavity 11.

[0068] The receiving cavity 11 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 11 through the opening. The receiving cavity 11 has a rear sidewall corresponding to the opening, and the damping structure 31 dampens the movement of the shelf assembly 2 toward the rear sidewall to reduce collision between the shelf assembly 2 and the rear sidewall.

[0069] 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.

[0070] The shelf connector is used to connect the housing 1 and the shelf assembly 2. Specifically, it is connected between the inner wall of the receiving cavity 11 and the shelf assembly 2 to enable the shelf assembly 2 to be moved into and out of the receiving cavity 11.

[0071] The mounting body 311 serves as a carrier and is fixed relative to the inner liner 12 after being installed into the receiving cavity 11 of the inner liner 12 of the household appliance.

[0072] The movable part 312 can be reciprocally mounted on the mounting body 311, that is, the movable part 312 has two unidirectional movement strokes, and the movement direction of the movable part 312 is opposite in the two unidirectional movement strokes.

[0073] The damping action of the movable part 312 needs to be fed back to the shelf assembly 2 of the household appliance so that the shelf assembly 2 also performs damping action, adapting to the application scenario of the household appliance. The movable part 312 and the trigger part 32 are respectively disposed on different structural components of the household appliance. During the movement of the movable part 312, it needs to engage and disengage with the trigger part 32, so that when the shelf assembly 2 requires damping action, the movable part 312 and the trigger part 32 engage; when the shelf assembly 2 does not require damping action, the movable part 312 and the trigger part 32 disengage.

[0074] The trigger part 32 is disposed on the shelf assembly 2. During the process of the shelf assembly 2 moving from front to back relative to the receiving cavity 11, the trigger part 32 can engage with the movable part 312, so that the shelf assembly 2 and the movable part 312 move synchronously, thereby damping the movement of the shelf assembly 2 toward the receiving cavity 11 and reducing the probability of the shelf assembly 2 colliding with the inner liner 12 of the household appliance.

[0075] It is understood that the damping structure 31 enables the damping activity of the movable part 312, thereby enabling the damping activity of the shelf assembly 2. The damping structure 31 needs to provide not only the pull-back force for the shelf assembly 2 to enter the inner liner 12 of the household appliance, but also the buffer force for the shelf assembly 2 to enter the inner liner 12, so as to achieve a smooth entry into the inner liner 12.

[0076] A self-priming unit 313 and a buffer unit 314 may be provided within the damping structure 31. The self-priming unit 313 provides a pull-back force for the shelf assembly 2 as it enters the inner liner 12 of the household appliance, and the buffer unit 314 provides a buffering force for the shelf assembly 2 as it enters the inner liner 12.

[0077] The damping structure 31 may consist only of the self-priming unit 313, providing only the pull-back force for the shelf assembly 2 as it enters the inner liner 12 of the household appliance, which can assist in absorbing energy through deformation after impact using an elastic buffer pad. Alternatively, the damping structure 31 may consist only of the buffer unit 314, providing only the buffering force for the shelf assembly 2 as it enters the inner liner 12, which can assist the user in applying force to push the shelf assembly 2 into the inner liner 12 of the household appliance. Of course, both the self-priming unit 313 and the buffer unit 314 may be provided simultaneously.

[0078] In some embodiments, please refer to Figures 5 to 8 The self-closing unit 313 includes a first elastic element 3131 disposed between the movable part 312 and the mounting body 311. During the forward and backward movement of the movable part 312, the first elastic element 3131 is always in a stretched state, so that the movable part 312 moves back under the elastic restoring force of the first elastic element 3131, thereby driving the shelf assembly 2 to move towards the receiving cavity 11. The stretching amount of the first elastic element 3131 gradually decreases, so that the movable part 312 moves under the elastic restoring force of the first elastic element 3131, thereby converting the elastic potential energy of the first elastic element 3131 into the kinetic energy of the movable part 312. In the case of household appliances, the movement of the shelf assembly 2 and the movable part 312 are associated, so that the shelf assembly 2 of the household appliance automatically moves towards the inner liner 12 of the household appliance.

[0079] The movable part 312 can be reciprocally mounted on the mounting body 311. In one unidirectional stroke of the movable part 312, the power of the movable part 312 comes from the release of the elastic potential energy of the first elastic element 3131; in the other unidirectional stroke, the power of the movable part 312 comes from human power, such as the force applied by the user when the shelf assembly 2 of the household appliance is pulled out from the inside.

[0080] The first elastic element 3131 can elastically store energy and release elastic potential energy. The first elastic element 3131 is always in a stretched state, that is, the first elastic element 3131 always has elastic deformation. During one unidirectional movement of the movable part 312, the stretch of the first elastic element 3131 gradually decreases, that is, the elastic deformation of the first elastic element gradually decreases. At this time, the first elastic element 3131 releases elastic potential energy, which is converted into the kinetic energy of the movable part 312 and the kinetic energy of the shelf assembly 2.

[0081] The first elastic element 3131 can be a spring, an elastic pad, or other elastic components, such as rubber blocks or silicone strips. These different types of elastic elements can be selected according to the specific design requirements, space constraints, and cost considerations of household appliances. Springs have good linear elastic characteristics and can maintain a relatively stable elastic force over a large deformation range; elastic pads can provide elasticity while also playing a certain role in cushioning and shock absorption; components such as rubber blocks and silicone strips not only have elasticity but may also have additional functions such as anti-slip and sealing.

[0082] In some embodiments, the damping structure 31 further includes a buffer unit 314 connected to the movable part 312 to dampen the movement of the shelf assembly 2 toward the receiving cavity 11. The buffer unit 314 provides a buffering force for the shelf assembly 2 to enter the inner liner 12, so that the shelf assembly 2 can smoothly enter the inner liner 12.

[0083] The buffer unit 314 serves a buffering function. The buffer unit 314 can be a damping unit, such as a damping cylinder or a damping hydraulic cylinder; the buffer unit 314 can also be a buffer elastic element, such as a spring or a rubber pad.

[0084] In some embodiments, please refer to Figures 5 to 6The buffer unit 314 includes a buffer cylinder and a telescopically connected link to the buffer cylinder. The link is connected to the movable part 312. The buffer cylinder is fixedly mounted on the mounting body 311. When the movable part 312 drives the shelf assembly 2 to move, the link extends and retracts within the buffer cylinder. The change in air or hydraulic pressure within the buffer cylinder generates a buffering force, effectively slowing the movement of the shelf assembly 2 towards the receiving cavity 11 and ensuring the shelf assembly 2 smoothly enters the inner liner 12. This design of the buffer unit 314 allows for flexible adjustment of the buffering effect according to different household appliance usage scenarios and needs, improving safety and comfort. Furthermore, the buffer cylinder and the link can be made of high-strength, corrosion-resistant materials to ensure the durability and reliability of the buffer unit 314.

[0085] In other embodiments, please refer to Figures 7 to 8 The buffer unit 314 includes a second elastic element 3141b, which is connected to the movable part 312 and the mounting body 311. During the movement of the movable part 312, the second elastic element 3141b is always in a compressed state. Specifically, as the movable part 312 moves from front to back, the compression of the second elastic element 3141b gradually increases to buffer the movement of the movable part 312. During the automatic movement of the shelf assembly 2 toward the inner liner 12 of the household appliance, the compression of the second elastic element 3141b gradually increases, increasing its elastic potential energy and storing energy to buffer the movement of the shelf assembly 2, thus reducing the probability of damage to the shelf assembly 2 due to collision.

[0086] The second elastic element 3141b can elastically store and release elastic potential energy. The second elastic element 3141b is always in a compressed state, meaning it always exhibits elastic deformation. During another unidirectional stroke of the movable part 312, the compression of the second elastic element 3141b gradually increases, meaning its elastic deformation gradually increases. At this point, the second elastic element 3141b is further compressed and stores energy to absorb the kinetic energy of the movable part 312 and the shelf assembly 2.

[0087] The second elastic element can be a spring, an elastic pad, or other elastic components, such as rubber blocks or silicone strips. These different types of elastic elements can be selected based on the specific design requirements, space constraints, and cost considerations of the household appliance. Springs have good linear elastic characteristics and can maintain relatively stable elastic force over a large deformation range; elastic pads can provide elasticity while also acting as a buffer and shock absorber; components such as rubber blocks and silicone strips not only have elasticity but may also have additional functions such as anti-slip and sealing.

[0088] It is understood that in the embodiment where the self-priming unit 313 includes the first elastic element 3131 and the buffer unit 314 includes the second elastic element 3141b, the interaction between the first elastic element 3131 and the second elastic element 3141b can be adapted to the entire stroke of the movable part 312. At any position of the movable part 312 in its stroke, the first elastic element 3131 and the second elastic element 3141b cooperate throughout the entire stroke.

[0089] During the movement of the movable part 312, when the movable part 312 moves in a certain direction, the first elastic element 3131 and the second elastic element 3141b will produce different elastic deformations according to their movement state. For example, when the movable part 312 just starts to move, the first elastic element 3131 may be in an initial elastic tension state, while the second elastic element 3141b begins to change elastically according to the direction of movement of the movable part 312. The two work together to provide suitable resistance for the movable part 312, preventing the movable part 312 from moving too fast or generating too large an impact.

[0090] As the movable part 312 continues to move, if the movable part 312 moves to the middle position of its stroke, the degree of elastic deformation of the first elastic member 3131 and the second elastic member 3141b will change, but they will always maintain mutual cooperation so that the movable part 312 can move smoothly at this position without sudden stops or accelerations.

[0091] When the movable part 312 moves to the end of its stroke, the first elastic element 3131 and the second elastic element 3141b will buffer and position the movable part 312 through their own elastic restoring force, ensuring that the movable part 312 stops accurately in the appropriate position. At the same time, they absorb the remaining kinetic energy of the movable part 312, preventing the movable part 312 from causing unnecessary shaking or rebound due to inertia, thereby ensuring the stability and reliability of the entire household appliance structure 100.

[0092] The damping action of the movable part 312 needs to be fed back to the shelf assembly 2 of the household appliance so that the shelf assembly 2 also performs damping action, adapting to the application scenario of the household appliance. The movable part 312 and the trigger part 32 are respectively disposed on different structural components of the household appliance. During the movement of the movable part 312, it needs to engage and disengage with the trigger part 32, so that when the shelf assembly 2 requires damping action, the movable part 312 and the trigger part 32 engage; and when the shelf assembly 2 does not require damping action, the movable part 312 and the trigger part 32 disengage.

[0093] The switching between the engagement and disengagement of the trigger part 32 and the movable part 312 can be achieved by partial deformation of the mounting body 311. For example, the movable part 312 can be made of a deformable material so that the trigger part 32 can be installed with the movable part 312.

[0094] In some embodiments, please refer to Figure 4 , Figure 6 and Figure 8 The movable part 312 reciprocates along the horizontal direction. The front end of the mounting body 311 is recessed to form a receiving groove 315. The movable part 312 includes a slider 3121, which is movably mounted relative to the mounting body 311. The first elastic member 3131 is connected between the slider 3121 and the mounting body 311. The slider 3121 can at least partially avoid being received in the receiving groove 315, so that the slider 3121 and the trigger part 32 can be separated. The slider 3121 can move out of the receiving groove 315, so that the slider 3121 and the trigger part 32 can be engaged. Through the cooperation of the slider 3121 and the receiving groove 315, the switching of engagement and disengagement of the trigger part 32 and the movable part 312 can be well adapted.

[0095] Further, in some embodiments, the slider 3121 includes a main body 3121a and a sliding buckle 3122 rotatably connected to the main body 3121a. A receiving slot 3122a is provided on the sliding buckle 3122 for the trigger part 32 to be inserted and engaged. When the sliding buckle 3122 rotates forward, it can avoid being accommodated within the receiving groove 315. The trigger part 32 disengages from the receiving slot 3122a, thereby separating the sliding buckle 3122 from the trigger part 32. When the sliding buckle 3122 rotates in the opposite direction, it can move out of the receiving groove 315, and the trigger part 32 is inserted into the receiving slot 3122a, so that the sliding buckle 3122 and the trigger part 32 are engaged. With this configuration, the movement mode of the movable part 312 can be decomposed into two types: one is linear movement in the front-back direction, and the other is rotational connection. The rotational connection allows the sliding buckle 3122 to avoid the trigger part 32 and separate from it, and also allows the sliding buckle 3122 and the trigger part 32 to engage.

[0096] When the sliding buckle 3122 rotates to the position corresponding to the trigger part 32, the sliding buckle 3122 can move in the front-back direction under the drive of the sliding piece 3121 until it engages with the trigger part 32. At this time, the shelf assembly 2 of the household appliance can automatically move into the inner liner 12 of the housing 1 under the drive of the movable part 312. Furthermore, by providing the receiving groove 315, a dedicated receiving space is provided for the sliding buckle 3122. When it is necessary for the sliding buckle 3122 and the trigger part 32 to separate, the sliding buckle 3122 can be stably accommodated therein, ensuring the stability and reliability of the structure operation.

[0097] The sliding buckle 3122 and the trigger part 32 can be joined by magnetic attraction or by a convex-concave fit. In some embodiments, the sliding buckle 3122 has a receiving slot 3122a, and the trigger part 32 has a trigger protrusion. The trigger protrusion can be inserted into the receiving slot 3122a to allow the sliding buckle 3122 and the trigger part 32 to engage. The precise engagement of the trigger protrusion and the receiving slot 3122a not only achieves a stable connection between the sliding buckle 3122 and the trigger part 32 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.

[0098] The sliding buckle 3122 and the main body 3121a can be connected in two ways: the sliding buckle 3122 can be rotatably installed along an axis extending in the left-right direction, and the trigger part 32 and the receiving slot 3122a can be inserted and engaged in the up-down direction; or the sliding buckle 3122 can be rotatably installed along an axis extending in the up-down direction, and the trigger part 32 and the receiving slot 3122a can be inserted and engaged in the left-right direction.

[0099] In the embodiment where the sliding buckle 3122 is rotated along an axis extending vertically, the sliding buckle 3122 can rotate flexibly around this axis. When rotated to a suitable position, the trigger part 32 can be precisely inserted into the receiving slot 3122a in the left-right direction. This installation and connection method can make full use of space and is more convenient during operation. Users can choose the appropriate rotation connection and insertion direction according to actual usage needs and space layout, further improving the applicability and flexibility of the structure. At the same time, this design reduces unnecessary parts and complex operation steps while ensuring structural stability, thereby reducing production costs and maintenance difficulty.

[0100] To guide the movement of the movable part 312 in the front-back direction, in some embodiments, a guide rib extending horizontally is provided on the mounting body 311, and a mating groove that slides and engages with the guide rib is provided on the slider 3121. The cooperation between the guide rib and the mating groove provides precise guidance for the movement of the slider 3121 relative to the mounting body 311, ensuring that the slider 3121 drives the sliding buckle 3122 to move stably in the front-back direction. This ensures that the movable part 312 moves accurately in the predetermined front-back direction, avoiding deviation or shaking, and improving the stability and accuracy of the entire household appliance structure 100.

[0101] In some embodiments, one end of the guide rib extends to connect to the receiving groove 315, which is located below the guide rib. That is, the guide rib guides the entire movement of the sheet body 3121a until the position where the sliding buckle 3122 rotates, so that the sheet body 3121a can always be effectively guided by the guide rib during the movement, ensuring the accuracy and stability of the rotation of the sliding buckle 3122.

[0102] In addition, the receiving groove 315 is located below the guide rib, that is, the guide rib and the receiving groove are located on different side end faces of the mounting body 311. This arrangement makes the guide rib and the receiving groove 315 spatially staggered, which can make full use of the space of the mounting body 311 and make the whole structure more compact and reasonable.

[0103] In order to mount the damping structure 31 onto the structure of a household appliance, in some embodiments, please refer to [reference needed]. Figures 1 to 4 The household appliance structure 100 also includes a mounting member 4 connected to the inner wall of the receiving cavity 11. The mounting member 4 has a plug-in plate portion 41 extending in the left-right direction. A limiting groove 3111 is provided on the mounting body 311. The plug-in plate portion 41 is inserted into the limiting groove 3111. By means of the cooperation between the plug-in plate portion 41 and the limiting groove 3111, when installing the damping structure 31, it is only necessary to insert the plug-in plate portion 41 into the limiting groove 3111 to realize the installation of the damping structure 31, making the installation of the damping structure 31 more convenient.

[0104] Furthermore, a limiting groove 3111 is provided on the mounting body 311; the side wall of the limiting groove 3111 is partially hollowed out to form a pressing snap 3112, which is used to press the plug plate portion 41 extending into the limiting groove 3111. Through the elastic pressing force of the pressing snap 3112, the static pressure of the plug plate portion 41 is increased, thereby increasing the static friction force of the plug plate portion 41 to detach outward, which greatly increases the risk of the plug plate portion 41 detaching.

[0105] To reduce interference with the movement of the shelf assembly 2, in some embodiments, the housing 1 includes an inner liner 12, the receiving cavity 11 is formed in the inner liner 12, the shelf assembly 2 includes a first shelf 21, and the mounting member 4 is connected to the side wall of the inner liner 12 and disposed below the first shelf 21. With this arrangement, the mounting member 4 is positioned below the first shelf 21 and connected to the side wall of the inner liner 12. When the first shelf 21 moves, the mounting member 4 and the damping structure 31 connected to it will not interfere with the movement of the first shelf 21, ensuring that the first shelf 21 can move relatively smoothly and improving the convenience and flexibility of the shelf assembly 2. At the same time, this layout also makes full use of the space on the side wall of the inner liner 12, making the overall structure more compact and reasonable.

[0106] In some embodiments, the household appliance structure 100 further includes a fixed slide rail 51 and a movable slide rail 52 slidably mounted relative to the fixed slide rail 51 in a front-to-back direction. The shelf assembly 2 includes a first shelf 21 connected to the movable slide rail 52. The trigger part 32 is disposed on the movable slide rail 52 or the first shelf 21. When the movable slide rail 52 moves from front to back relative to the fixed slide rail 51, the movable part 312 of the damping structure 31 and the trigger part 32 interact to generate a damping force. This damping force can effectively reduce the movement speed of the movable slide rail 52 and the first shelf 21, thereby reducing the impact force generated by the shelf assembly 2 during the process of moving into and out of the receiving cavity 11 due to excessive speed. This avoids violent collisions between the shelf assembly 2 and the rear wall or other components of the receiving cavity 11, improving the stability and durability of the entire household appliance structure 100. At the same time, it makes the movement of the shelf assembly 2 more stable and smooth, providing convenience for users.

[0107] 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 receiving cavity 11 of the inner liner 12. 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 receiving cavity 11 of the inner liner 12, but also be raised to a suitable position after being moved out of the receiving cavity 11 of the inner liner 12, so as to reduce the user's bending over and facilitate the user's loading and unloading operations.

[0108] Specifically, in some embodiments, the shelf connector further includes a swing arm 62, one end of which is hinged to the receiving cavity 11 of the inner liner 12, and the other end of which is hinged to the fixed slide rail 51, that is, in application scenarios where the shelf assembly 2 not only moves in the front-back direction, but also moves in the up-down direction.

[0109] It should be noted that the fixed slide rail 51 is not fixedly installed relative to the receiving cavity 11 of the inner liner 12. Instead, after the swing arm 62 swings to its limit position, the fixed slide rail 51 is fixed relative to the swing arm 62, that is, there is no relative movement between the fixed slide rail 51 and the swing arm 62.

[0110] The movable slide rail 52 is movable relative to the inner liner 12 and also relative to the shelf connector. The movable slide rail 52 is fixedly installed relative to the first shelf 21.

[0111] Specifically, the swinging motion of the swing arm 62 causes the first shelf 21 to switch between a low position and a high position. Corresponding to the low position, the fixed slide rail 51 and the movable slide rail 52 move relative to each other, so that the first shelf 21 has an initial bottom position that is entirely inside the inner liner 12 and a bottom position that is at least partially outside the inner liner 12 and is waiting to be lifted. During the process of the first shelf 21 moving from the bottom position waiting to be lifted to the initial bottom position, the damping structure 31 is used to dampen the movement of the first shelf 21 into the inner liner 12. The damping structure 31 is applied to the process of the first shelf 21 returning from the bottom position waiting to be lifted to the initial bottom position to buffer the movement of the first shelf 21. Through the damping structure 31, the movement of the first shelf 21 during the return stroke is smooth and stable, improving the user experience.

[0112] When the first shelf 21 needs to be raised from its initial bottom position, the swing arm 62 swings upward around the hinge point, causing the first shelf 21 to gradually change from a low position to a high position. At the same time, the movable slide rail 52 slides forward along the fixed slide rail 51, causing the first shelf 21 to partially move out of the receiving cavity 11 for easy access to items. After the items are placed, the swing arm 62 swings downward, causing the first shelf 21 to descend. The movable slide rail 52 slides backward along the fixed slide rail 51, and the first shelf 21 returns to its initial bottom position within the receiving cavity 11.

[0113] 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.

[0114] Inside the dishwasher, a second shelf 7 is also provided inside the inner liner 12 of the housing 1. After the first shelf 21 is stored in the receiving cavity 11 of the housing 1, the second shelf 7 is above the first shelf 21. After the first shelf 21 moves upward to the top position, the first shelf 21 is in front of the second shelf 7.

[0115] The following describes the user's experience using household appliances, with the first shelf 21 as a reference:

[0116] 1. The first shelf 21 is in the initial position at the bottom, such as... Figure 10 As shown:

[0117] 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 21 is located within the receiving cavity 11 of the household appliance. Figure 10 As can be seen, the first shelf 21 is retracted into the receiving cavity 11. At this time, the fixed slide rail 51 and the movable slide rail 52 move relative to each other to the minimum stroke position. At this time, the trigger part 32 and the sliding buckle 3122 of the movable part 312 are engaged. The first elastic element 3131 and the second elastic element 3141b cooperate, or the first elastic element 3131 and the damper cooperate. The first elastic element 3131 is at the minimum tensile elastic deformation position, and the second elastic element 3141b is at the maximum compressive elastic deformation position. Alternatively, the damper is at the minimum length position to dampen the first shelf 21 from continuing to move backward after moving to the preset position to impact the inner liner 12 of the household appliance.

[0118] 2. The first shelf 21 is in the bottom position to be lifted, such as... Figure 11 As shown:

[0119] This state refers to the user pulling out the first shelf 21 from the receiving cavity 11, or the user lowering the first shelf 21 after using it. In these states, the first shelf 21 is at the opening of the receiving cavity 11. At this time, the fixed slide rail 51 and the movable slide rail 52 move relative to each other to their maximum stroke. At this time, the sliding buckle 3122 of the trigger part 32 and the movable part 312 separates. The first elastic element 3131 is at the maximum tensile elastic deformation, and the second elastic element 3141b is at the minimum compressive elastic deformation, or the damper is at its maximum length.

[0120] 3. The first shelf 21 is at its maximum lifting position at the top, such as... Figure 12 As shown:

[0121] This state occurs when the user lifts the first shelf 21 to its top limit position. At this time, the fixed slide rail 51 and the movable slide rail 52 move relative to each other to their maximum stroke. At this time, the sliding buckle 3122 of the trigger part 32 and the movable part 312 separates. The first elastic element 3131 is at the maximum tensile elastic deformation position, and the second elastic element 3141b is at the minimum compressive elastic deformation position. Alternatively, the damper is at its maximum length position.

[0122] The following will describe a complete user experience flow, based on the above embodiments:

[0123] When a user needs to use a household appliance, they first open the appliance's door. The user then pulls the first shelf 21 forward from the bottom initial position out of the receiving cavity 11 to the bottom lifting position. With the combined effect of the swing arm 62, the user continues to pull the first shelf 21 forward and upward, causing the first shelf 21 to move from the bottom lifting position to the top lifting limit position. The user continues to pull the first shelf 21 forward, causing the first shelf 21 to move from the top lifting limit position to the top locking position. In the locked state, the user can retrieve and place items in the first shelf 21 with reduced bending frequency.

[0124] When the user finishes retrieving or placing the item, the user pushes the first shelf 21 back to unlock it and move it from the top unlocked position to the top raised limit position. The user then lowers the first shelf 21 to move it from the top raised limit position to the bottom ready-to-raise position. The user continues to push the first shelf 21 back to move it from the bottom ready-to-raise position to the bottom initial position. When the first shelf 21 is in the bottom initial position, the user can close the door to complete the use of the household appliance.

[0125] 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.
