[0048] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0049] First, see Figure 1 Define the height direction of shelf 100 as Z.

[0050] Firstly, see... Figure 1 , Figure 2 and Figure 3This application provides a shelf 100, including a base frame 110 and side walls. A side frame 120 is connected to the base frame 110 and forms a cutlery area 130 with the base frame 110; the side frame 120 is provided with an outwardly protruding structure 121; along a first direction, the outwardly protruding structure 121 protrudes from the side frame 120 in a direction away from the cutlery area 130 to increase the size of the cutlery area 130; wherein, the first direction intersects with the height direction (Z) of the shelf 100.

[0051] Those skilled in the art will understand that by providing an outwardly protruding structure 121 protruding in the first direction toward the direction away from the tableware area 130 on the side shelf 120, the size of the tableware area 130 in the first direction can be increased, the number of tableware that the tableware area 130 can accommodate can be increased, and the cleaning efficiency of the dishwasher can be improved when the shelf 100 is applied to the dishwasher.

[0052] It should be noted that the first direction intersects with the height direction of the shelf 100, and the first direction can be the left-right direction or the front-back direction of the shelf 100. This embodiment takes the left-right direction of the shelf 100 as an example for explanation, and defines the first direction as X.

[0053] Understandably, the side shelf 120 includes a first side shelf 122 and a second side shelf 123, which are arranged along the X direction on opposite sides of the base shelf 110. The first side shelf 122 and the second side shelf 123 are opposite each other along the X direction and connected to the base shelf 110 to form a tableware area 130.

[0054] The protruding structure 121 can be disposed on the first side shelf 122 and / or the second side shelf 123. On the first side shelf 122, the protruding structure 121 protrudes relative to the first side shelf 122 in the X direction toward the side of the first side shelf 122 opposite to the cutlery area 130, thereby increasing the size of the cutlery area 130 in the X direction and thus increasing the number of cutlery that the shelf 100 can hold. On the second side shelf 123, the protruding structure 121 protrudes relative to the second side shelf 123 in the X direction toward the side of the second side shelf 123 opposite to the cutlery area 130, thereby increasing the size of the cutlery area 130 in the X direction and thus increasing the number of cutlery that the shelf 100 can hold.

[0055] It should be noted that when the first side frame 122 and / or the second side frame 123 are provided with an outward protrusion structure 121, the size of the outward protrusion structure 121 on the first side frame 122 and the outward protrusion structure 121 on the second side frame 123 protruding out of the tableware area 130 in the X direction can be the same or different.

[0056] Optionally, the shelf 100 in this embodiment further includes a roller 140, which is connected to the side frame 120 and located on the side where the protruding structure 121 is located; the roller 140 has a first end face 141, which faces the side frame 120 on which the protruding structure 121 is provided; along the first direction, the protruding structure 121 is located between the side frame 120 and the first end face 141.

[0057] See for those skilled in the art Figure 1 , Figure 2 and Figure 3 Understandably, the rollers 140 are rotatably mounted on the first side shelf 122 and the second side shelf 123, so that the user can push and pull the shelf 100 to push the tableware into or remove the tableware from the dishwasher.

[0058] It is easy to understand that when the shelf 100 moves relative to the inner liner via the rollers 140, the rollers 140 can engage with the track provided on the inner wall of the inner liner. In this embodiment, the protruding structure 121 is located between the side frame 120 and the first end face 141 of the rollers 140, avoiding motion interference between the protruding structure 121 and the structure on the inner wall of the inner liner, making the pushing and pulling movement of the shelf 100 relative to the inner liner smoother, thus facilitating user operation.

[0059] It should be noted that, in this embodiment, the roller 140 may be located at the bottom of the side shelf 120 along the Z direction, so that when the shelf 100 is located in the inner tub of the dishwasher, it may be located at the bottom or middle of the inner tub along the Z direction. Alternatively, the roller 140 may be located at the middle of the side shelf 120 along the Z direction, so that when the shelf 100 is located in the inner tub of the dishwasher, it may be located at the middle or top of the inner tub along the Z direction.

[0060] For example, there are at least two rollers 140. Along the height direction of the shelf 100, at least two rollers 140 are spaced apart on the side frame 120. The rolling centers of at least two adjacent rollers 140 are located on opposite sides of the convex structure 121, and the maximum size of the convex structure 121 is smaller than the length of the line connecting the rolling centers of the two adjacent rollers 140.

[0061] See Figure 2 The first side frame 122 is provided with three rollers 140, which are spaced apart along the Z direction. The distance between two adjacent rollers 140 along the Z direction can be the same or different. The second side frame 123 is provided with three rollers 140, which are spaced apart along the Z direction. The distance between two adjacent rollers 140 on the first side frame 122 and the second side frame 123 along the Z direction can be the same or different, so as to adapt to the slide rail structure in the inner tub of dishwashers of different specifications.

[0062] See for those skilled in the art Figure 2 It can be understood that, in the first side shelf 122, along the Z direction, the outward convex structure 121 is located between the rolling centers of the two rollers 140 near the top of the first side shelf 122, and in the second side shelf 123, along the Z direction, the outward convex structure 121 is located between the rolling centers of the two rollers 140 near the top of the second side shelf 123. The maximum dimension of the outward convex structure 121 along the Z direction is smaller than the length of the line connecting the rolling centers of the corresponding two rollers 140, so as to prevent the tableware in the tableware area 130 formed by the outward convex structure 121 from interfering with the rolling of the rollers 140, thereby improving the smoothness of the movement of the shelf 100 into and out of the inner drum of the dishwasher through the rollers 140.

[0063] Optionally, in the first side frame 122, along the Z direction, the outwardly protruding structure 121 may also be located between the rolling centers of the two rollers 140 near the bottom of the first side frame 122, and in the second side frame 123, along the Z direction, the outwardly protruding structure 121 may also be located between the rolling centers of the two rollers 140 near the bottom of the second side frame 123.

[0064] It should be noted that, in this embodiment, the protruding structure 121 on the first side frame 122 is located between the first side frame 122 and the first end face 141 of each roller 140 disposed on the first side frame 122, and the protruding structure 121 on the second side frame 123 is located between the second side frame 123 and the first end face 141 of each roller 140 disposed on the second side frame 123.

[0065] It should be noted that the number of rollers 140 on the first side frame 122 can also be two, four, etc., and the number of rollers 140 on the second side frame 123 can also be two, four, etc.

[0066] Optionally, along the height direction of the shelf 100, the lowest point of the protruding structure 121 is higher than the top of the roller 140. Understandably, during the process of the shelf 100 moving in and out of the dishwasher's inner tub via the roller 140, the plane where the top of the roller 140 is located is a motion plane of the roller 140. When the lowest point of the protruding structure 121 is higher than the top of the roller 140, it means that the protruding structure 121 is located above the motion plane of the roller 140, avoiding motion interference between the protruding structure 121 and the roller 140, making the movement of the shelf 100 relative to the dishwasher's inner tub via the roller 140 smoother.

[0067] It is understood that the convex structure 121 in the embodiments of this application has many forms. As an optional implementation, the projection of the convex structure 121 on the ZX plane is an arc-shaped structure, or the projection of the convex structure 121 on the XY plane is an arc-shaped structure.

[0068] Combination Figure 2and Figure 3 In some embodiments, the convex structure 121 includes a first connecting section 1211, a protruding section 1212, and a second connecting section 1213. The first connecting section 1211, the protruding section 1212, and the second connecting section 1213 are connected sequentially along the height direction (Z) of the shelf 100. The end of the first connecting section 1211 opposite to the protruding section 1212 is connected to the side frame 120, and the end of the second connecting section 1213 opposite to the protruding section 1212 is connected to the side frame 120.

[0069] In this embodiment, the first connecting segment 1211 may be inclined relative to the horizontal direction (X) toward the top or bottom of the shelf 100. Specifically, the first connecting segment 1211 extends relative to the side shelf 120 along the X direction toward the side opposite to the cutlery area 130. It is understood that the second connecting segment 1213 may be inclined relative to the horizontal direction (X) toward the top or bottom of the shelf 100. Specifically, the second connecting segment 1213 extends relative to the side shelf 120 along the X direction toward the side opposite to the cutlery area 130.

[0070] It should be noted that the tilt orientation of the first connecting segment 1211 and the second connecting segment 1213 relative to the horizontal direction (X) can be the same or different, and this embodiment does not require this. In addition, at least one of the first connecting segment 1211 and the second connecting segment 1213 can be a broken line segment, an arc segment, a straight segment, etc., and this embodiment does not limit this.

[0071] For example, see Figure 2 and Figure 3 In this embodiment, the protruding section 1212 is connected to the end of the first connecting section 1211 and the second connecting section 1213 away from the side frame 120. The protruding section 1212 is located outside the tableware area 130 along the X direction through the first connecting section 1211 and the second connecting section 1213. Along the X direction, the first connecting section 1211, the protruding section 1212 and the second connecting section 1213 form part of the tableware area 130, which can increase the size of the tableware area 130 along the first direction (X), thereby increasing the number of tableware that the tableware area 130 can hold, and improving the cleaning efficiency of the dishwasher when the shelf 100 is applied to the dishwasher.

[0072] Furthermore, the first connecting section 1211, the protruding section 1212, and the second connecting section 1213 are arranged along the Z direction and connected in sequence. On the basis of increasing the size of the tableware area 130 along the X direction, the structural strength of the corresponding side shelf 120 is improved, thereby enhancing the load-bearing capacity of the shelf 100.

[0073] It should be noted that the protruding segment 1212 in this embodiment can be a broken line segment, an arc segment, a straight segment, etc., and this embodiment does not require it to be. Furthermore, the protruding segment 1212 can be arranged parallel to or intersecting with the Z direction.

[0074] For details, please refer to Figure 2 , Figure 3 and Figure 4 In this embodiment, the protruding section 1212 extends along the height direction of the shelf 100; the end of the first connecting section 1211 connected to the protruding section 1212 is inclined away from the direction where the tableware area 130 is located relative to the end of the first connecting section 1211 connected to the side shelf 120; and / or, the end of the second connecting section 1213 connected to the protruding section 1212 is inclined away from the direction where the tableware area 130 is located relative to the end of the second connecting section 1213 connected to the side shelf 120.

[0075] Thus, by tilting the first connecting segment 1211 and the second connecting segment 1213, two guiding slopes are formed. The tableware does not need to be precisely aligned. After contacting the first connecting segment 1211 and the second connecting segment 1213, it can slide into place more smoothly. When taking out the tableware, the tilted first connecting segment 1211 and the second connecting segment 1213 can reduce interference with the edge of the tableware, reducing the difficulty of the user's operation of taking out and putting away the tableware and the risk of bumps.

[0076] See Figure 4 For some bowls, the bowls are placed in the cutlery area 130 and can be abutted by the first connecting section 1211. The first connecting section 1211 provides support for the bowls, making them stable in the cutlery area 130, reducing shaking during the cleaning process, and thus reducing the cleaning noise of the dishwasher.

[0077] See Figure 2 , Figure 3 and Figure 4 The base frame 110 in this embodiment includes a base frame body 111, an inclined base frame 112, and a movable base frame 113. The inclined base frame 112 is connected to the base frame body 111 and is inclined relative to the horizontal direction. The movable base frame 113 is movably connected to the inclined base frame 112 and has a folded state and an unfolded state. When the movable base frame 113 is in the unfolded state, it is inclined relative to the horizontal direction and is consistent with the tilting direction of the inclined base frame 112. At least a portion of the inclined base frame 112, the movable base frame 113, and the protruding structure 121 form a sub-tableware area 130.

[0078] It is understood that, in the embodiments of this application, see [reference] Figure 2The tilting base 112 can tilt relative to the horizontal direction (X) toward the side where the tableware area 130 is located. Alternatively, the tilting base 112 can tilt relative to the horizontal direction (X) toward the side away from the tableware area 130; this embodiment does not require this. This embodiment, through the setting of the tilting base 112, achieves the tilting of the tableware relative to the horizontal direction (X), which facilitates contact between the water jet from the spray arm and the tableware, improving cleaning efficiency and cleaning effect.

[0079] Furthermore, the tableware is tilted relative to the X direction by the inclined base 112. After cleaning, the water on the tableware flows towards the bottom of the tableware under the action of gravity, thereby improving the drying efficiency and drying effect of the tableware.

[0080] For example, the movable base 113 is rotatably connected to the tilting base 112, and forms a folded state and an unfolded state during rotation relative to the tilting base 112. Different rotation angles of the movable base 113 relative to the tilting base 112 result in different tilt angles between the movable base 113 and the X direction. Consequently, the size of the sub-tableware area 130 enclosed by the movable base 113, the tilting base 112, and the protruding structure 121 varies to accommodate tableware of different sizes, improving the tableware applicability of the shelf 100. It is understood that different rotation angles of the movable base 113 relative to the tilting base 112 result in different tilt angles for the tableware. When the tableware is tilted, after cleaning, the water accumulated on the tableware flows towards the bottom of the tableware under the action of gravity, thereby improving the drying efficiency and effect of the tableware.

[0081] For details, please refer to Figure 2 and Figure 4 The tableware area 130 includes a first tableware area 131 and a second tableware area 132; the first tableware area 131 and the second tableware area 132 are arranged along a first direction; the outward protruding structure 121 includes a first outward protruding structure 1214 and a second outward protruding structure 1215; along the first direction, the first outward protruding structure 1214 is disposed on the side frame 120 adjacent to the first tableware area 131, and the second outward protruding structure 1215 is disposed on the side frame 120 adjacent to the second tableware area 132; along the first direction, the inclined base frame 112 and the movable base frame 113 located in the first tableware area 131 are both inclined toward the side where the base frame body 111 is located; and / or, along the first direction, the inclined base frame 112 and the movable base frame 113 of the second tableware area 132 are both inclined toward the side where the base frame body 111 is located.

[0082] Understandably, the first protruding structure 1214 is disposed on the first side frame 122 to increase the size of the first tableware area 131 along the first direction (X), and the second protruding structure 1215 is disposed on the second side frame 123 to increase the size of the second tableware area 132 along the first direction (X). On the basis of increasing the number of tableware that the tableware area 130 can accommodate, the tableware can be cleaned and stored in separate areas.

[0083] Furthermore, see Figure 2 and Figure 4 In this embodiment of the application, by setting the inclined base 112 and movable base 113 of the first tableware area 131 to be inclined in the first direction toward the side where the base body 111 is located; and / or, the inclined base 112 and movable base 113 of the second tableware area 132 to be inclined in the first direction toward the side where the base body 111 is located, the size of the tableware area 130 in the X direction is increased while the size of the shelf 100 in the Z direction is reduced, so as to avoid interference between the base 110 and other structures in the inner tub, and make the movement of the shelf 100 in and out of the inner tub of the dishwasher smooth, so as to facilitate user operation.

[0084] Secondly, embodiments of this application provide a dishwasher, including: the shelf 100 provided in the first aspect.

[0085] The dishwasher in this embodiment includes the shelf 100 mentioned in the first aspect, which increases the number of dishes that can be cleaned, thereby improving the cleaning efficiency of the dishwasher.
