[0061] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0062] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0063] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0064] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0065] Household appliances such as dishwashers, refrigerators, freezers, and storage cabinets are often equipped with shelves, some of which are located relatively low. Therefore, when storing items on these shelves, users need to bend over to access them. For example, when accessing and placing bowls in the lower basket of a dishwasher, users need to bend over without raising or lowering the lower basket, resulting in a poor user experience.

[0066] To this end, the industry has set up a lifting mechanism to raise the low-position shelf to a certain height. However, after the shelf is raised, when the user puts items in, the swing arm of the lifting mechanism may swing downward due to the load, causing the shelf to move up and down accordingly, which is not conducive to the user taking and placing items, and the user experience is poor.

[0067] Based on this, the present invention proposes a locking member to solve the problem of how to prevent the storage rack from moving up and down due to load changes. Figures 1 to 14 This is a structural diagram of the household appliance provided by the utility model.

[0068] See also Figures 1 to 5In one embodiment of the present invention, the locking member 3 is used on the lifting mechanism 100 of the household appliance 1000 and is disposed on the first storage rack 300. The locking member 3 cooperates with the swing arm 2 of the lifting mechanism 100 to restrict relative movement between the swing arm 2 and the first storage rack 300 when the swing arm 2 swings the first storage rack 300 upward to the top lifting limit position and the first storage rack 300 moves to the top locking position. The locking member 3 includes a lock body 31, at least one guide rail, and a limiting structure. One side of the lock body 31 in the left-right direction serves as a mounting side 311. The guide rail is disposed on the mounting side 311 and has an arcuate segment connecting its head end. The arcuate segment is used to provide an arcuate sliding track for the sliding portion on the swing arm 2. The limiting structure is disposed corresponding to the tail end of the guide rail. The limiting structure is used to limit the sliding portion up and down and / or forward and backward when the first storage rack 300 moves to the top locking position.

[0069] In the technical solution of the present invention, the limiting structure is provided at the tail end of the guide rail, so that when the first shelf 300 is lifted to the top lifting limit position, the user only needs to continue to drive the first shelf 300 so that the first shelf 300 continues to move, and the sliding part at the tail end of the guide rail can slide onto the limiting structure, so that the limiting structure can limit the sliding part up and down and / or forward and backward, so as to limit the first shelf 300 to the top locking position. In this way, when in use, the user first pulls the first shelf 300 forward to let the first shelf 300 The first rack 300 is locked when the user moves the first rack 300 forward and upward to the top lifting limit position. The first rack 300 is then driven to move forward or backward to stop the swing arm 2 from swinging. During the entire lifting and locking process, the user only needs to drive the first rack 300 to move to complete the lifting and locking of the first rack 300, thereby preventing the first rack 300 from moving up and down due to load changes, making it convenient for users to take and put items, and the operation is simple.

[0070] In the present invention, the user is used as a reference for direction. Forward refers to the direction toward the user, or toward the side of the household appliance 1000 with a door body; backward refers to the direction opposite to the forward direction, specifically the direction away from the user; and up and down refers to the direction with gravity as a reference. Furthermore, since the first storage rack 300 is supported on the swing arm 2 by the lock body 31, the locking member 3 needs to have a certain hardness and strength. There are many materials for it. Specifically, the lock body 31 can be made of a metal alloy such as steel or aluminum alloy, or an inorganic non-metallic material such as ceramic, or a polymer material such as plastic. As long as it can support the first storage rack 300 after the load, this invention does not limit it. Furthermore, the lock body 31 can have many shapes, such as a rectangle or a pentagon, and this invention does not limit it.

[0071] Furthermore, the specific implementation form of the limiting structure is not limited and can be in the form of a limiting groove 351, a limiting rib, a limiting surface, etc., and is not limited here. One side of the lock body 31 in the left-right direction is a mounting side 311. The side of the lock body 31 opposite the mounting side 311 is fixedly mounted on the first storage rack 300, so that it can move with the first storage rack 300.

[0072] It should be noted that the guide rail has an arc-shaped section connected to its head end to match the sliding trajectory of the sliding part on the swing arm 2, so as to guide the sliding part of the swing arm 2. Furthermore, the number of the guide rails and the sliding part is not limited, and can be one, or multiple, etc., which is not limited here. The specific implementation form of the guide rails and the sliding part is not limited. The guide rail can be configured as a guide groove 321, and the sliding part can be configured as a sliding column, a pulley, etc. It can also be configured as a guide rib, and the sliding part can be configured as a slide groove. For example, the sliding part includes two slide columns arranged at intervals, and the interval between the two slide columns constitutes the slide groove. It can also be that the sliding part is directly set as a sliding protrusion, and then a slide groove is opened on it, etc., which is not limited here.

[0073] It should also be noted that the household appliance 1000 may be a dishwasher, an oven, a toaster oven, a refrigerator, etc. The household appliance 1000 includes a housing 200, wherein a receiving cavity 201 is formed in the housing 200. A first storage rack 300 is connected to the receiving cavity 201 via a lifting mechanism 100. Utensils to be placed on the first storage rack 300 include tableware such as bowls, plates, chopsticks, and cutlery, as well as baked ingredients or items to be refrigerated.

[0074] Furthermore, some household appliances 1000 have only one shelf, such as the first shelf 300. Some may have multiple shelves. In embodiments where multiple shelves are provided in the household appliance 1000, two shelves may be provided, such as the first shelf 300 and the second shelf 400. When the two shelves are positioned one above the other, they may be referred to as an upper shelf and a lower shelf. In the embodiments of the present invention, the first shelf 300 corresponds to the upper shelf, and the second shelf 400 corresponds to the lower shelf.

[0075] The first rack 300 needs to be moved out of the accommodating cavity 201 of the household appliance 1000, then lifted to a suitable position, and finally locked in a suitable position. Specifically, after the door of the household appliance 1000 is opened, the user needs to put items in or take out items from the first rack 300. The user often pulls the first rack 300 forward. During the movement of the first rack 300, a complex movement process occurs, that is, the first rack 300 moves forward and upward at the same time. At this time, the lifting mechanism 100 will follow the movement and support the first rack 300.

[0076] The first rack 300 has several important positions during its movement, the most common of which are the bottom storage position (such as the attached Figure 6 As shown), the bottom position to be lifted (as shown in the attached Figure 9 As shown), top lifting limit position (as shown in the attached Figure 11 shown) and top locked position (as shown in the attached Figure 13 shown).

[0077] When the first storage rack 300 has four positions, namely, a bottom storage position, a bottom position to be lifted, a top lifting limit position, and a top locking position, when the swing arm 2 is at the lower swing limit position, the corresponding first storage rack 300 is at the bottom storage position and the bottom position to be lifted; when the swing arm 2 is at the upper swing limit position, the corresponding first storage rack 300 is at the top lifting limit position and the top locking position.

[0078] The guide rail can be entirely curved or partially curved, and the present invention does not limit this. Specifically, in one embodiment of the present invention, please refer to Figures 2 to 4The guide rail includes a first guide rail 32 for slidingly cooperating with the first sliding portion 23 of the swing arm 2. The arc section of the first guide rail 32 is a first arc section 321. The first arc section 321 is set in an arc shape that bends downward from the head end to the tail end of the first guide rail 32. The limiting structure includes a first limiting portion 34 set corresponding to the tail end of the first arc section 321. The first limiting portion 34 is used to limit the first sliding portion 23 up and down.

[0079] In this embodiment, the first guide rail 32 extends downward from its head end to the tail end. Correspondingly, during the lifting process of the first sliding portion 23, the first sliding portion 23 moves downward, which can guide the movement trajectory of the first storage rack 300 during the lifting process, thereby improving its stability during the movement. When the first storage rack 300 reaches the top lifting limit position, the first sliding portion 23 moves along the first guide rail 32 to its tail end. Then, the first storage rack 300 continues to move to the top locking position. At this time, the first sliding portion 23 moves from the first guide rail 32 to the first limiting portion 34 and is limited by the first limiting portion 34. In this way, by providing the first arc segment 321 to guide the first sliding portion 23 to move downward to the tail end of the first guide rail 32, the first limiting portion 34 can limit the first sliding portion 23 up and down.

[0080] Furthermore, the first arc segment 321 is configured to be upwardly convex, so that the motion trajectory of the first arc segment 321 can match the sliding path of the first sliding portion 23, thereby enabling the first guide rail 32 to guide the first sliding portion 23 to move to the first limiting portion 34, thereby limiting the first limiting portion 34 in the upper and lower positions. Of course, in other embodiments, the first arc segment 321 can also be configured to be downwardly concave, etc., and the present invention is not limited to this.

[0081] In one embodiment of the present invention, please refer to Figure 2 and Figure 3 The first guide rail 32 is configured as a first guide groove 321. The head end of the first guide groove 321 penetrates the lock body 31 for the first sliding portion 23 on the swing arm 2 to slide into. The tail end of the first guide groove 321 penetrates the lock body 31 downward to form a lower end notch. A stop surface 341 is formed at the periphery of the lower end notch and at a rear position. The stop surface 341 forms the first limiting portion 34.

[0082] In this embodiment, when the lifting mechanism 100 lifts the first storage rack 300 upward to the upper limit position, the first sliding portion 23 slides along the first guide groove 321 to the stop surface 341 to limit the upward rotation of the swing arm 2.

[0083] Furthermore, the specific formation method of the abutment surface 341 is not limited. For example, a limiting rib can be provided on the side surface of the installation side of the lock body, and the abutment surface 341 can be formed by the lower surface of the limiting rib; or a notch can be formed on the side surface of the installation side of the lock body, the notch being connected to the first guide groove 34, and the upper wall surface of the notch forming the abutment surface 341. All of the above are within the scope of protection of the present utility model. Specifically, in this embodiment, the tail end of the first guide groove is provided through the lower end of the lock body 31, and the lower end surface of the lock body 31 forms the abutment surface 341. In this way, the outer wall surface of the lock body 31 can directly form the first limiting portion 34, so that there is no need to additionally provide the first limiting portion 34, which is convenient for production and processing and can save costs.

[0084] Of course, see Figure 4 and Figure 5 In other embodiments, the first guide rail 32 may also be configured with a guide rib. Specifically, the first guide rail 32 is configured as a first guide rib 322 ; the first limiting portion 34 includes a limiting boss 342 provided on the rear side of the tail end of the first guide rib 32 .

[0085] Correspondingly, at this time, the first sliding part 23 is configured as a slide groove. For example, the first sliding part 23 includes two sliding columns arranged at intervals, and the interval between the two sliding columns constitutes the slide groove. The sliding part can also be directly set as a sliding protrusion, and then a slide groove is opened on it, and so on.

[0086] During the lifting process of the first storage rack 300, the first sliding portion 23 moves on the first guide rib 322. When the first storage rack 300 swings upward to the top lifting limit position and moves to the top locking position, the first sliding portion 23 moves below the limiting boss 342 and is limited by the limiting boss 342.

[0087] See also Figures 2 to 4The guide rail includes a second guide rail 33, which is located in front of the first guide rail 32 and on the lower side of the first guide rail 32, and is used to slide with the second sliding portion 24 of the swing arm 2. The second guide rail 33 includes a second arc section 3311 and a second flat section 3312. The second arc section 3311 is set in an arc shape that gradually bends upward from the head end to the tail end of the second guide rail 33. One end of the second flat section 3312 is connected to the tail end of the second arc section 3311, and the other end extends backward. The limiting structure includes a second limiting portion 35 corresponding to the second flat section 3312. The second limiting portion 35 is used to limit the second sliding portion 24 forward and backward.

[0088] In this embodiment, the head end of the second guide rail 33 is located in front of the head end of the first guide rail 32. During the lifting process, the second sliding portion 24 of the swing arm 2 contacts the head end of the second arc segment 3311 first, and the swing arm 2 rotates upward, and the second sliding portion 24 also rotates upward. During the rotation process, the first sliding portion 23 moves to contact the head end of the first guide rail 32 and continues to move along the extension direction of the first guide rail 32. When the first storage rack 300 reaches the top lifting limit position, the first sliding portion 23 and the second sliding portion 24 reach the tail end of the first guide rail 32 and the second flat segment 3312 respectively, and the first storage rack 300 is lifted. 00 continues to move to the top locking position. At this time, the second sliding portion 24 moves from the second flat section 3312 to the second limiting portion 35 and is limited by the second limiting portion 35. In this way, by providing the first guide rail 32 and the second guide rail 33, one of them can guide the swing arm 2 in the up and down directions, and the other can guide the swing arm 2 in the front and back directions, which helps to improve the stability of the first storage rack 300 during movement. By providing the first limiting portion 34 and the second limiting portion 35, the first sliding portion 23 and the second sliding portion 24 can be limited respectively, thereby improving the stability of the first storage rack 300 during lifting and locking.

[0089] In one embodiment of the present invention, please refer to Figures 2 to 5 The second arc segment 3311 is convex so that the movement trajectory of the second arc segment 3311 can match the sliding path of the second sliding part 24, so that the second guide rail 33 can guide the second sliding part 24 to move to the second limiting part 35 to limit the second limiting part 35 forward and backward.

[0090] In one embodiment, see Figure 2 、 Figure 3 and Figure 5 The second guide rail 33 is configured as a second guide groove 331, the head end of the second guide groove 331 passes through the lock body 31, and the second sliding portion 24 on the swing arm 2 slides into it. The second limiting portion 35 is configured as a limiting groove 351, and the limiting groove 351 is connected to the tail end of the second guide groove 331 and extends backward. Of course, in another embodiment, the second flat section 3312 constitutes the limiting groove 351.

[0091] In this embodiment, the head end of the second guide groove 331 is set through the lock body 31, so that when the locking member 3 moves forward with the first storage rack 300, the head end of the second guide groove 331 can contact the second sliding portion 24, allowing the second sliding portion 24 on the swing arm 2 to slide in, and then the second sliding portion 24 moves along the extension direction of the second guide groove 331. After the first storage rack 300 moves to the top lifting limit position, the first storage rack 300 can continue to move forward to the top locking position, and the second sliding portion 24 can move forward to the top locking position. The second sliding portion 24 moves from the second guide slot 331 into the limiting slot 351. At this time, the limiting slot 351 can limit the second sliding portion 24 in the front-to-back and / or up-to-down directions. Thus, by providing the limiting slot 351 extending rearward, the user only needs to pull the first shelf 300 forward to complete the lifting and locking of the first shelf 300 during the entire lifting and locking process. This allows the first shelf 300 to be pulled forward and locked, aligning with the movement direction of the first shelf 300, facilitating user operation. Of course, in other embodiments, the first shelf 300 can also be locked backward. That is, after the first shelf 300 moves to the rear end of the second guide slot 331, the first shelf 300 is pushed backward to lock the first shelf 300. However, this method is opposite to the movement direction of the first shelf and may provide a poor user experience.

[0092] The limiting groove 351 can be arranged in a variety of ways, and can be arranged to extend horizontally in the front-to-back direction, such as Figure 3 and Figure 4 As shown in , it can also be arranged tilted in the up and down directions, such as Figure 2As shown in FIG, specifically, in one embodiment of the present invention, the limiting groove 351 is arranged upwardly inclined in a direction away from the second guide groove 331. This inclined arrangement allows the second guide groove 331 to smoothly transition to the limiting groove 351. When the locking member 3 moves forward, the second sliding portion 24 can smoothly slide into the limiting groove 351. Simultaneously, the limiting groove 351 extends upwardly to cooperate with the abutment surface 341 to restrict the vertical movement of the swing arm 2 and the locking member 3, thereby achieving forward locking. Of course, in other embodiments, the limiting groove 351 may also extend downwardly inclined, etc., and the present invention is not limited thereto.

[0093] Furthermore, if the inclination angle of the limiting groove 351 is small, it is not easy to limit the second sliding part 24. If the inclination angle of the limiting groove 351 is large, it is not easy for the second sliding part 24 to slide into the limiting groove 351. For this reason, in this embodiment, the angle between the limiting groove 351 and the front-to-back direction is α, where 15°≤α≤60°, which makes it easy for the second sliding part 24 to slide into the limiting groove 351 and can limit the second sliding part 24 to prevent the swing arm 2 and the locking member 3 from moving relative to each other in the front-to-back and upward directions. It can be understood that the angle α between the limit groove 351 and the front-to-back direction can be an integer value of 60°, or any integer value between 15° and 60°, such as 30°, 40°, 50°, etc. Of course, it can also be an angle value between any two of the above integers, such as the degree between 50° and 60° can be 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, etc. Of course, it can also be some decimal degree values. The above values ​​are all within the protection scope of the present utility model.

[0094] In one embodiment of the present invention, please refer to Figure 2 and Figure 3At the junction of the limiting groove 351 and the second guide groove 331, a retaining rib 36 is provided on the inner sidewall 2012 of the limiting groove 351. The retaining rib 36 forms a damping structure that secures the second sliding portion 24 in place, reminding the user that the first storage rack 300 has been fully engaged, thereby improving the user experience. Furthermore, the retaining rib 36 may be one or more, and the present invention is not limited thereto. Specifically, two retaining ribs 36 are provided, one on each opposite side of the limiting groove 351. The provision of two retaining ribs 36 can, on the one hand, further reduce the width of the limiting groove 351, increase the interference of the second sliding portion 24, and enhance the damping feedback. On the other hand, the sliding trajectory of the second sliding portion 24 is maintained in the middle of the limiting groove 351, allowing the second sliding portion 24 to slide smoothly into the limiting groove 351.

[0095] It is understandable that there are many ways to form the clamping rib 36 and the lock body 31. For example, the clamping rib 36 and the lock body 31 can be integrally formed or assembled, and the present invention does not limit this.

[0096] Since the lock body 31 is to support the first storage rack 300, it needs to have a certain hardness and strength, so that the lock body 31 is not easily deformed and the second sliding portion 24 is not easily passed through the clamping rib 36. To this end, in this embodiment, the installation side 311 of the lock body 31 is provided with a deformation groove 37 on the periphery of the limiting groove 351. In this way, by providing the deformation groove 37, the strength of the limiting groove 351 is weakened, so that the limiting groove 351 can be deformed in its width direction, thereby allowing the second sliding portion 24 to slide through the clamping rib 36.

[0097] In one embodiment of the present invention, the deformation groove 37 is arranged in an arc shape. Thus, the arc shape is adopted to surround the limiting groove 351 within the deformation groove 37, thereby reducing the strength of the limiting groove 351 and facilitating the sliding of the second sliding portion 24. In another embodiment, multiple deformation grooves 37 are provided, and the multiple deformation grooves 37 are arranged at intervals. Thus, by providing multiple deformation grooves 37, the limiting groove 351 is surrounded within the deformation groove 37, thereby reducing the strength around the limiting groove 351, allowing the second sliding portion 24 to slide smoothly over the clamping rib 36. At the same time, the multiple deformation grooves 37 are arranged at intervals to avoid the small distance between the limiting groove 351 and the first guide groove 321, so as to avoid weakening the strength of the first guide groove 321 and reducing the possibility of the first sliding portion 23 sliding out of the first guide groove 321.

[0098] To achieve this, please refer to Figure 6 、 Figure 9 、 Figure 11 and Figure 13 The present invention further proposes a lifting mechanism 100 for lifting a first storage rack 300 of a household appliance 1000, so that the first storage rack 300 can be lifted and switched between a bottom position to be lifted and a top lifting limit position. The lifting mechanism 100 includes a fixed arm 1, a swing arm assembly, and a locking member 3. The fixed arm 1 is installed in a receiving cavity 201 of the household appliance 1000. The swing arm assembly includes at least a first swing arm 2. The two ends of the first swing arm 2 are correspondingly provided with a first hinged mounting portion 21 and a second hinged mounting portion 22. The first hinged mounting portion 21 is installed on the fixed arm 1, and the second hinged mounting portion 22 is used to be directly or indirectly installed on the first storage rack 30. 0, the locking member 3 is the above-mentioned locking member 3. Thus, when in use, the user first pulls the first rack 300 forward to move the first rack 300 forward, so that the swing arm 2 of the lifting mechanism 100 can swing the first rack 300 forward and upward to the top lifting limit position, and then continues to drive the first rack 300 to stop the swing arm 2 from swinging, thereby locking the first rack 300. During the entire lifting and locking process, the user only needs to drive the first rack 300 to complete the lifting and locking of the first rack 300, so as to prevent the first rack 300 from moving up and down due to load changes, thereby making it convenient for users to take and put items, and having high ease of operation.

[0099] It should be noted that the specific structure of the locking member 3 refers to the above embodiments. Since the lifting mechanism 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0100] In some embodiments, see Figure 1 and Figure 12The lifting mechanism 100 further includes a slide rail structure 5, which includes a plurality of slide rails that are telescopically and slidably connected to each other. The plurality of slide rails include at least a first slide rail 51 and a tail slide rail 52. The first slide rail 51 is directly or indirectly connected to the second hinged mounting portion, and the tail slide rail 52 is connected to the first rack 300. The swing arm 2 can swing the first rack 300 forward and upward from the bottom waiting position to be lifted to the top lifting limit position. When the first rack 300 is in the top lifting limit position, the plurality of slide rails extend forward and backward and can slide relative to each other, so that the first rack 300 can slide to the top locking position, so that the first rack 300 can switch between the bottom storage position and the bottom waiting position. The positional relationship of the first rack 300 is adjusted by the telescopic movement of the plurality of slide rails. In this way, the first rack 300 can be moved to the bottom storage position and stored in the accommodating cavity 201.

[0101] It should be noted that the connecting member 4 is connected to the first section of the slide rail 51, and the connection can be achieved by bonding or welding, that is, the connecting member 4 can be glued to the first section of the slide rail 51 by glue; of course, welding can also be used, for example, the connecting member 4 and the first section of the slide rail 51 are both set to metal materials, such as iron or steel, and the connecting member 4 can be welded to the first section of the slide rail 51.

[0102] In some embodiments, the connecting member 4 and the first section of the slide rail 51 are integrally formed, that is, the connecting member 4 and the first section of the slide rail 51 are one component, which reduces the number of parts and saves assembly time and cost.

[0103] The tail section slide rail 52 is connected to the first rack 300. The first rack 300 can generally be formed by a number of small round ribs arranged alternately in the horizontal or vertical direction. The connection of the slide rail can be assisted by a connecting block. The connecting block is provided with some mechanisms such as slots for retaining the small round ribs on the first rack 300. The connecting block is also provided with a screw connection structure, which is directly connected to the tail section slide rail 52 through the screw connection structure, thereby making the connection more secure.

[0104] Furthermore, the present invention does not limit the number of slide rails in the slide rail structure 5. For example, it can be 2-section slide rails, 3-section slide rails, or multiple-section slide rails with more than 3 sections, such as 4-section, 5-section, 6-section, 7-section, etc. The present invention does not limit this. Specifically, in this embodiment, the slide rail structure 5 also includes an intermediate slide rail 53, which is arranged between the first slide rail 51 and the tail slide rail 52. In this way, by providing the intermediate slide rail 53, the sliding stroke of the first rack 300 is increased, so that the first rack 300 can completely slide out of the accommodating cavity 201, so as to avoid the first rack 300 interfering with other structures in the shell 200, such as the second rack 400, when the lifting mechanism 100 lifts the first rack 300. Furthermore, the number of the intermediate slide rails 53 can be one or more, and the present invention does not limit this. However, the greater the number of the intermediate slide rails 53, the more complex the slide rail structure 5 is and the higher the cost is. Therefore, in this embodiment, only one intermediate slide rail 53 is provided, which can not only meet the movable stroke requirements of the first storage rack 300, but also reduce the cost of the slide rail structure 5.

[0105] In one embodiment of the present invention, the number of the swing arms 2 is not limited, and can be only one or two. In the embodiment in which two swing arms 2 are provided, the lifting mechanism 100 partially forms a four-bar linkage structure, which is a parallelogram four-bar linkage structure. Figure 11 Two swing arms 2 are provided, and the lifting mechanism 100 further includes a connector 4 connected to the first slide rail 51. The two second hinged mounting portions 22 are both hinged to the connector 4. By providing the connector 4, a hinged fitting portion can be provided on the connector 4 to connect the swing arm 2 to the first rack 300, which can simplify the structure of the first rack 300 and facilitate the setting of the first rack 300.

[0106] It should be noted that during the entire movement of the lifting mechanism 100 , the state of the connecting member 4 remains unchanged. Thus, the state of the first storage rack 300 remains unchanged during the entire movement, thereby ensuring better stability for the storage of items to be placed.

[0107] Furthermore, the portion of the connector 4 used to connect to the first shelf 300 can be set to a constant horizontal position, so that the first shelf 300 remains in a constant horizontal position during movement. It should be noted that the constant horizontal position can be absolutely horizontal or at a certain angle to the horizontal position, for example, within a range of 10°.

[0108] In one embodiment of the present invention, please refer to Figure 1 If the length of the limiting groove 351 is too long, it is not convenient for the second sliding part 24 to slide in and out, and when the length of the limiting groove 351 is too short, the limiting effect of the second sliding part 24 is not good. For this reason, in this embodiment, the length of the limiting groove 351 is L1, and the width of the second sliding part 24 is D, wherein D / 3≤L1≤2 / 3D, which makes it convenient for the second sliding part 24 to slide in or out of the limiting groove 351, and can also limit the second sliding part 24 to prevent the swing arm 2 and the locking member 3 from moving relative to each other in the front and back directions.

[0109] To achieve the above objectives, the present invention also proposes a household appliance 1000, comprising a shell 200, a lifting mechanism 100 and a first storage rack 300. The shell 200 forms a accommodating cavity 201. The lifting mechanism 100 includes the lifting mechanism 100 as described above. The fixed arm 1 of the lifting mechanism 100 is provided on the side wall 2012 of the accommodating cavity 201. The first storage rack 300 is hingedly connected to the swing arm 2 of the lifting mechanism 100. The lifting mechanism 100 enables the first storage rack 300 to be lifted and switched between a bottom position to be lifted and a top lifting limit position.

[0110] In some household appliances 1000, only one, two, or more shelves are provided. In the technical solution of the present invention, a second shelf 400 is further provided in the accommodating cavity 201. Corresponding to the top lifting limit position, the lower end of the first shelf 300 protrudes upward from the lower end of the second shelf 400. That is, at the lifting limit position of the first shelf 300, the lifting height of the first shelf 300 is higher than that of the second shelf 400. At this time, the lifting height is larger, which reduces the frequency of users bending over and improves the user experience.

[0111] It should be noted that, in an embodiment in which there are two shelves in the household appliance 1000, the first shelf 300 is a lower shelf and the second shelf 400 is an upper shelf. When the first shelf 300 is in the top storage position and the second shelf 400 is in the accommodating cavity 201, the first shelf 300 is below the second shelf 400, and the two are arranged opposite to each other.

[0112] In view of some of the above embodiments, the user needs to alternately use the first rack 300 and the second rack 400. That is, when the first rack 300 is raised, the second rack 400 should be kept in the accommodating cavity 201 as much as possible; when the second rack 400 is used, the first rack 300 should be kept in the accommodating cavity 201 as much as possible, or the second rack 400 should not be raised as much as possible.

[0113] Of course, with respect to the upper end of the first rack 300 and the upper end of the second rack 400, in some embodiments, corresponding to the top lifting limit position and the top lifting locking position of the first rack 300, the upper end of the first rack 300 protrudes upward from the upper end of the second rack 400, that is, under the premise that the depths of the first rack 300 and the second rack 400 are the same, the first rack 300 can be located at a higher position.

[0114] In a product corresponding to the household appliance 1000 being a dishwasher, the first rack 300 corresponds to the lower basket of the dishwasher, and the second rack 400 corresponds to the upper basket of the dishwasher. When the lower basket of the dishwasher is in use, the lifting mechanism 100 lifts the lower basket of the dishwasher to a position higher than the upper basket. In this state, the operating height is the same as when the user uses the upper basket of the dishwasher, or a higher height, which provides a better user operating experience.

[0115] The following describes the process of a user using the household appliance 1000 based on the relevant structure of the household appliance 1000, with the first rack 300 as a reference:

[0116] 1. The first storage rack 300 is in the bottom storage position, such as Figure 6-8 As shown:

[0117] This state is when the user is not using the appliance, has just started using the appliance, or has finished using the appliance. In these states, the first shelf 300 is in the accommodating cavity 201 of the household appliance 1000. As can be seen from the figure, the first shelf 300 is retracted into the accommodating cavity 201. At this time, the swing arm 2 is at the lower limit position, and the sliding portion is separated from the guide rail.

[0118] 2. The first shelf 300 is at the bottom position to be lifted, such as Figure 9-10 As shown:

[0119] This state is when the user pulls out the first storage rack 300 from the accommodating cavity 201, or when the user lowers the first storage rack 300 after using it. In these states, the first storage rack 300 is located at the opening of the accommodating cavity 201, and the swing arm 2 is still at the lowering limit position. At this time, the sliding portion contacts the head end of the guide rail. When there are multiple guide rails, for example, including a first guide rail 32 and a second guide rail 33, there are multiple corresponding sliding portions, including a first sliding portion 23 and a second sliding portion 24. At this time, the second sliding portion 24 is located at the head end of the second guide rail 33. Then, the first storage rack 300 continues to move forward and upward.

[0120] 3. The first storage rack 300 is at the top lifting limit position, such as Figure 11-12 As shown:

[0121] This state is when the user lifts the first rack 300, or when the user exits the locked state after using the first rack 300. In these states, the first rack 300 is at the maximum height of the lift. Figure 11 It can be seen that at this time, the sliding portion of the swing arm 2 slides to the tail end of the guide rail, and the swing arm 2 is at the upper swing limit position.

[0122] 4. The first storage rack 300 is in the top locked position, as shown in FIG. Figure 13-14 As shown:

[0123] This state is a locked state after the user lifts the first shelf 300. At this time, the user can take out and put down the items to be placed. In these states, the first shelf 300 is at the maximum height of the lift. Figure 13-14 It can be seen that the first storage rack 300 moves forward a certain distance in the top locking position relative to the top lifting limit position, and the sliding portion of the swing arm 2 slides from the tail end of the guide rail to the limiting structure. The sliding portion of the swing arm 2 is limited by the limiting structure, and the swing arm 2 is still in the upper swing limit position.

[0124] The following is an introduction to the complete user process:

[0125] When the user needs to use the household appliance 1000, the user first opens the door of the household appliance 1000, and then pulls the first shelf 300 forward from the bottom storage position out of the accommodating cavity 201 to the bottom lifting position; under the swinging action of the swing arm 2 of the lifting mechanism 100, the user continues to pull the first shelf 300 forward and upward, so that the first shelf 300 moves from the bottom lifting position to the top lifting limit position; the user continues to pull the first shelf 300 forward, and the first shelf 300 moves from the top lifting limit position to the top locking position. In the locked state, the user can take and place items to be placed in the first shelf 300 without bending over frequently.

[0126] When the user finishes taking or placing items to be placed, the user pushes the first rack 300 backward to unlock the first rack 300 and move it from the top unlocked position to the top lifting limit position; the user lowers the first rack 300 to move it from the top lifting limit position to the bottom position to be lifted; the user continues to push the first rack 300 backward to move it from the bottom position to be lifted to the bottom storage position. When the first rack 300 is in the bottom storage position, the user can close the door to complete the use of the household appliance 1000.

[0127] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
