[0039] The present application discloses an inner liner 1000, which will be described in detail below in conjunction with a dishwasher. It will be understood that the inner liner 1000 disclosed in the present application is not limited to being applied to dishwashers, but can also be applied to other devices having the inner liner 1000.

[0040] As shown in Figures 1 to 5, in some embodiments of the present application, the inner container 1000 includes a middle frame 1100 and a back panel 1200, wherein the middle frame 1100 is provided with a flange 1150 located at the rear side, and the back panel 1200 needs to be connected to the flange 1150. A first groove 1310 is provided on a side of the back panel 1200 or the flange 1150 facing the other of the back panel 1200 and the flange 1150 (a side refers to a side of the one), and a second groove 1320 is provided on a side of the back panel 1200 or the flange 1150 facing the other of the back panel 1200 and the flange 1150 (a side refers to a side of the one). The second groove 1320 is provided adjacent to the interior of the inner container 1000 relative to the first groove 1310. The first groove 1310 is used to accommodate a fluid sealant, and the second groove 1320 is used to receive the sealant overflowing from the first groove 1310. By setting the first groove 1310 and the second groove 1320, the first groove 1310 is used to accommodate fluid sealant. The sealant is applied in the first groove 1310. When the middle frame 1100 and the back panel 1200 are assembled, the sealant is squeezed, and part of the sealant overflows from the first groove 1310 and is transferred to the second groove 1320. This prevents the overflowed sealant from being transferred to the interior of the inner tank 1000, thereby preventing the user from observing the overflowed sealant and improving the texture of the product.

[0041] Specifically, a dishwasher comprises an inner container 1000, the interior of which is formed into a receiving chamber 1400. The dishwasher's bowl basket and spray arm are positioned within the receiving chamber 1400. Dishware is placed on the bowl basket. When the dishes need to be washed, water sprayed from the spray arm is directed toward the dishes in the basket. The water then falls back to the bottom of the receiving chamber 1400, where it is circulated and pumped away, continuing to be delivered to the spray arm, thereby achieving a cyclical cleaning of the dishes. The inner container 1000 is generally square in structure and includes a back panel 1200 and a middle frame 1100. The back panel 1200 is connected to the rear side of the middle frame 1100, thereby connecting the back panel 1200 and the middle frame 1100 to form the receiving chamber 1400. The front side of the middle frame 1100 is open and communicates with the receiving chamber 1400. The front side of the middle frame 1100 can be opened and closed by the dishwasher door. When the dishwasher door is open, dishes can be placed into the receiving chamber 1400. When the dishwasher door is closed, the dishes can be washed. It can be understood that the orientations in this application are based on the normal placement of the dishwasher. The side of the dishwasher facing the user is the front, the side away from the user is the back, the side corresponding to the user's left hand is the left, the side corresponding to the right hand is the right, the side close to the ground is the bottom, and the side away from the ground is the top.

[0042] The connection scheme between the back panel 1200 and the middle frame 1100 is as follows: the middle frame 1100 has a flange 1150 located on the rear side of the middle frame 1100. For example, as shown in Figures 1 and 2, the middle frame 1100 includes a top panel 1110, a left side panel 1130, and a right side panel 1140. The top panel 1110 is arranged on top of the left side panel 1130 and the right side panel 1140. It can be that the top panel 1110, the left side panel 1130, and the right side panel 1140 are three parts respectively, which are connected together by a connection means. It can also be that the top panel 1110, the left side panel 1130, and the right side panel 1140 are formed by bending the same plate. The top panel 1110, the left side panel 1130, and the right side panel 1140 each have a flange 1150. It can be understood that the middle frame 1100 is not limited to the aforementioned examples. In some embodiments, as shown in Figures 3 and 4, the middle frame 1100 can also include a bottom plate 1120, which is arranged at the bottom of the left plate 1130 and the right plate 1140, and the bottom plate 1120 also has a flange 1150.

[0043] As shown in Figure 5, the flange 1150 is arranged away from the interior of the inner liner 1000 (the accommodating chamber 1400). When assembling the back panel 1200 and the middle frame 1100, the back panel 1200 and the flange 1150 are abutted together and connected to each other. There are many ways to connect the back panel 1200 and the flange 1150. For example, the back panel 1200 and the flange 1150 are connected and fixed to each other by welding, riveting, screw connection, etc. Of course, as long as the back panel 1200 and the flange 1150 can be fixed together, the connection methods between the back panel 1200 and the flange 1150 will not be listed one by one here.

[0044] As mentioned above, the interior of the inner tank 1000 (the accommodating chamber 1400) will be used to clean tableware. Therefore, for a water-related environment, it is necessary to perform a sealing treatment between the back panel 1200 and the flange 1150. In the related art, a glue (sealant) treatment is performed between the back panel 1200 and the flange 1150. However, when the back panel 1200 is connected to the flange 1150, the back panel 1200 and the flange 1150 jointly squeeze the sealant. Under the action of squeezing, part of the sealant leaks into the interior of the inner tank 1000 (the accommodating chamber 1400) through the junction of the back panel 1200 and the flange 1150. The sealant leaked into the inner tank 1000 is in an irregular state, which will reduce the quality of the dishwasher. In particular, when the user sees the sealant through the interior of the inner tank 1000 (the accommodating chamber 1400), it will form a feeling of poor quality, which will bring adverse effects. To this end, in this embodiment, a first groove 1310 and a second groove 1320 are provided to solve the problem.

[0045] A first groove 1310 is provided on a side of one of the back plate 1200 and the flange 1150 facing the other of the back plate 1200 and the flange 1150 (one side refers to one side of the one), and a second groove 1320 is provided on a side of one of the back plate 1200 and the flange 1150 facing the other of the back plate 1200 and the flange 1150 (one side refers to one side of the one). That is, the first groove 1310 and the second groove 1320 can be arranged in a variety of ways. For example, as shown in FIG5, FIG6 and FIG7, the side 1230 of the back plate 1200 facing the flange 1150 is provided with the first groove 1310, and the side 1230 of the back plate 1200 facing the flange 1150 is also provided with the second groove 1320; or as shown in FIG8, the side 1230 of the back plate 1200 facing the flange 1150 is provided with the first groove 1310, and the side 1150 of the flange 1150 facing the back plate 1200 is provided with the second groove 1320. 3 is provided with a second groove 1320; it is also possible that, as shown in FIG9, the side 1153 of the flange 1150 facing the back plate 1200 is provided with a first groove 1310, and the side 1230 of the back plate 1200 facing the flange 1150 is provided with a second groove 1320; of course, there is also such a situation, as shown in FIG10, the side 1153 of the flange 1150 facing the back plate 1200 is provided with a first groove 1310, and the side 1153 of the flange 1150 facing the back plate 1200 is also provided with a second groove 1320.

[0046] As shown in Figure 5, compared with the first groove 1310, the second groove 1320 is closer to the interior of the inner tank 1000 (the accommodating chamber 1400). Before assembling the back panel 1200 and the middle frame 1100, a fluid sealant needs to be applied to the first groove 1310. It can be understood that the so-called fluid sealant is a sealant that is roughly liquid and easy to change in shape. This makes it convenient to apply the sealant to the first groove 1310. The fluid sealant needs to undergo a solidification process to become a solid sealant, thereby forming a seal between the back panel 1200 and the flange 1150. In order for the sealant to form a good seal between the back plate 1200 and the flange 1150, a sufficient amount of sealant needs to be applied to the first groove 1310. Then, when the back plate 1200 and the middle frame 1100 are assembled, the back plate 1200 and the flange 1150 are brought into contact with each other. The fluid sealant in the first groove 1310 will flow toward other positions between the back plate 1200 and the flange 1150 under the mutual extrusion of the back plate 1200 and the flange 1150, that is, part of the sealant will flow out of the first groove 1310. 1310 overflows. In this embodiment, a second groove 1320 is provided at a position closer to the accommodating cavity 1400 relative to the first groove 1310. The overflowed sealant can enter the second groove 1320. The second groove 1320 forms a buffer for the overflowed sealant, thereby preventing the overflowed sealant from leaking into the accommodating cavity 1400 through the junction between the back plate 1200 and the flange 1150, and avoiding the formation of irregular sealant in the accommodating cavity 1400, thereby improving the quality of the dishwasher.

[0047] As mentioned above, there are many ways to set the first groove 1310 and the second groove 1320. They can be set on the back plate 1200, on the flange 1150, or on both the back plate 1200 and the flange 1150. In order to set the first groove 1310 and the second groove 1320, in combination with Figures 5, 6, 7 and 10, in some embodiments of the present application, the first groove 1310 and the second groove 1320 are set on the side of one of the back plate 1200 and the flange 1150 facing the other, that is, the first groove 1310 and the second groove 1320 are only set on the side 1230 of the back plate 1200 facing the flange 1150, or the first groove 1310 and the second groove 1320 are only set on the side 1153 of the flange 1150 facing the back plate 1200, which facilitates the processing of the first groove 1310 and the second groove 1320.

[0048] Specifically, the back panel 1200 and the middle frame 1100 are two different components with different shapes and / or sizes. If the first groove 1310 is provided on one of the back panel 1200 and the flange 1150, and the second groove 1320 is provided on the other of the back panel 1200 and the flange 1150, then the corresponding first groove 1310 and second groove 1320 need to be machined on the back panel 1200 and the flange 1150, respectively, thus requiring different equipment or construction. Therefore, in this embodiment, the first groove 1310 and the second groove 1320 are provided on both the back panel 1200 and the flange 1150, so that only the same part needs to be machined, which is more convenient and quick. In particular, most of the middle frames 1100 and the back panels 1200 are sheet metal parts. It is sufficient to form two grooves (a first groove 1310 and a second groove 1320) by punching the back panel 1200 or to form two grooves (a first groove 1310 and a second groove 1320) by punching the flange 1150 of the middle frame 1100. There is no need to punch the flange 1150 of the middle frame 1100 and the back panel 1200 separately, which is beneficial to improving production efficiency.

[0049] Furthermore, in combination with Figures 5, 6 and 7, in some embodiments of the present application, the first groove 1310 and the second groove 1320 are arranged on the side 1230 of the back plate 1200 facing the flange 1150, which can reduce the difficulty of production. Specifically, when the first groove 1310 and the second groove 1320 are set on the flange 1150 of the middle frame 1100, the first groove 1310 and the second groove 1320 need to be processed on the flange 1150. The flange 1150 is much smaller than other positions of the middle frame 1100 and presents a certain angle. Therefore, if it is necessary to process the first groove 1310 and the second groove 1320 on the flange 1150, it is more difficult. In particular, when the middle frame 1100 is a sheet metal part, the flange 1150 is formed by bending part of the sheet metal part. At this time, the flange 1150 and other positions of the middle frame 1100 are roughly perpendicular, and the difficulty of processing the first groove 1310 and the second groove 1320 on the flange 1150 is greatly increased.

[0050] To this end, in this embodiment, the first groove 1310 and the second groove 1320 are arranged on the back plate 1200. The back plate 1200 generally has a flat structure, so the first groove 1310 and the second groove 1320 can be more conveniently processed on the back plate 1200. Compared with processing the first groove 1310 and the second groove 1320 on the flange 1150, processing the first groove 1310 and the second groove 1320 on the back plate 1200 will greatly reduce the production difficulty, which is conducive to improving production efficiency and reducing production costs.

[0051] As shown in conjunction with FIG. 5 , FIG. 6 and FIG. 7 , in some embodiments of the present application, the first groove 1310 and the second groove 1320 are designed to be alternately arranged, so that the sealant can be better filled in the first groove 1310 .

[0052] Specifically, before assembling the back plate 1200 and the middle frame 1100 together, it is necessary to first apply a fluid sealant to the first groove 1310. During the application of the sealant, the sealant may not be completely filled in the first groove 1310 due to the construction process, for example, bubbles are formed in certain positions. In this embodiment, the first groove 1310 is designed to be arranged alternately with the second groove 1320, for example, the first groove 1310 and the second groove 1320 are alternately 1mm to 5mm, which can be the case. The second grooves 1320 are spaced 1mm, 2mm, 3mm, 4mm, or 5mm apart. Thus, during the process of attaching the back plate 1200 to the flange 1150, the sealant will first fill the first groove 1310. Then, under the action of extrusion, some of the sealant will overflow into the second groove 1320 through the space between the first groove 1310 and the second groove 1320. By designing the first groove 1310 and the second groove 1320 to be spaced apart, it is more conducive to the sealant first filling the first groove 1310 and then overflowing, thereby improving the sealing effect. It is understood that the so-called spaced arrangement refers to the spaced arrangement along the extension direction of the junction of the back plate 1200 and the flange 1150, in the inside-outside direction (the inside refers to the inside of the liner 1000, and the outside refers to the outside of the liner 1000).

[0053] In order to facilitate the sealant overflowing from the first groove 1310 to overflow into the second groove 1320, in combination with Figures 5 and 6, in some embodiments of the present application, an overflow gap 1330 is formed between the back plate 1200 and the flange 1150, and the overflow gap 1330 is arranged between the second groove 1320 and the first groove 1310, and the spacing of the overflow gap 1330 is L1. The position where the second groove 1320 is set is the inner side relative to the first groove 1310, then, the spacing between the part 1210 of the back plate 1200 set on the outside of the first groove 1310 and the part 1151 of the flange 1150 set on the outside of the first groove 1310 is L2, and L1 must be greater than L2, so that it is more convenient to transfer the sealant overflowing from the first groove 1310 to the second groove 1320.

[0054] Specifically, when the back panel 1200 is assembled with the middle frame 1100, the sealant in the first groove 1310 is squeezed by the back panel 1200 and the flange 1150, and the sealant in the first groove 1310 can overflow toward the inside of the first groove 1310 and toward the outside of the first groove 1310. Although the sealant in the first groove 1310 overflows toward the outside of the first groove 1310 and then overflows to be exposed outside the inner tank 1000, it will not be observed by the user (the dishwasher is wrapped in an outer shell), but it may cause other effects. For example, workers on the production line can easily touch the overflowed sealant. To this end, in this embodiment, a portion 1220 of the back plate 1200 disposed between the second groove 1320 and the first groove 1310 and a portion 1152 of the flange 1150 disposed between the second groove 1320 and the first groove 1310 are alternately arranged to form a flow gap 1330. The spacing L1 of the flow gap 1330 is greater than the spacing L2 between the portion 1210 of the back plate 1200 disposed outside the first groove 1310 and the portion 1151 of the flange 1150 disposed outside the first groove 1310. Therefore, the sealant in the first groove 1310 is more likely to overflow into the second groove 1320 through the flow gap 1330. Thus, the sealant overflowing into the second groove 1320 also serves as a seal after solidification. It is understood that L2 can be 0, that is, the back plate 1200 and the flange 1150 are tightly attached to each other.

[0055] Furthermore, in some embodiments of the present application, the overflow gap 1330 extends along the extension direction of the second groove 1320 and the first groove 1310, that is, it extends roughly along the periphery of the back plate 1200, so that the sealant overflowing from various positions of the first groove 1310 can be directly transferred to the second groove 1320 through the overflow gap 1330.

[0056] Specifically, the length of the overflow gap 1330 is adapted to the length of the second groove 1320 and the first groove 1310. When assembling the back panel 1200 and the middle frame 1100, sealant will be applied in the extension direction of the first groove 1310. Since the overflow gap 1330 is adapted to the length of the first groove 1310, when assembling the back panel 1200 and the middle frame 1100, there is a need for sealant overflow in the extension direction of the first groove 1310. In this way, the sealant overflowing from different parts enters the second groove 1320 more evenly, preventing more sealant overflowing in some local positions and less sealant overflowing in some local positions, so that the overflowed sealant is distributed as evenly as possible in the second groove 1320, forming a better sealing effect.

[0057] As shown in Figure 7, in some embodiments of the present application, the distance between the two opposite sides of the first groove 1310 is L3, and the distance between the two opposite sides of the second groove 1320 is L4, satisfying the condition that L3 is greater than L4, so that the sealant of the first groove 1310 forms a larger sealing area.

[0058] Specifically, since the seal between the back panel 1200 and the middle frame 1100 is primarily formed by the sealant in the first groove 1310, in this embodiment, the distance between the two opposing sides of the first groove 1310 is designed to be larger than the distance between the two opposing sides of the second groove 1320. Taking the first groove 1310 located on the back panel 1200 as an example, the sealing area formed between the sealant in the first groove 1310 and the flange 1150 is also larger, thereby ensuring a good sealing effect. It is understood that the connection between the back panel 1200 and the flange 1150 needs to be tightly fitted, and the distance between the two opposing sides of the second groove 1320 is designed to be relatively small, thereby ensuring the contact area between the back panel 1200 and the flange 1150 and ensuring the stability of the connection between the back panel 1200 and the flange 1150. It is understood that the opposite sides are referenced to the inside-out direction, such as the left-right direction shown in Figure 7.

[0059] As shown in Figure 5, in some embodiments of the present application, the depth of the first groove 1310 is designed to be D1, and the depth of the second groove 1320 is designed to be D2, and the condition D1 is less than D2 needs to be met. In this way, while ensuring the effective contact area between the back panel 1200 and the flange 1150, the overflowing sealant is buffered.

[0060] Specifically, as mentioned above, the connection between the back panel 1200 and the flange 1150 requires that the back panel 1200 and the flange 1150 are overlapped together and then connected by some connection means. Compared with the related art, this embodiment adds an additional groove (the second groove 1320), which will reduce the contact area between the back panel 1200 and the flange 1150. The reduced contact area will affect the connection stability between the back panel 1200 and the flange 1150. In order to minimize the impact as much as possible, the depth D2 of the second groove 1320 is designed to be greater than the depth D1 of the first groove 1310. In this way, the distance L4 between the opposite sides of the second groove 1320 can be designed to be smaller than the distance L3 between the opposite sides of the first groove 1310. In this way, the contact area between the back panel 1200 and the flange 1150 can be maximized. The greater the depth D2 of the second groove 1320, the more effectively it can buffer the overflowed sealant, which is equivalent to having a greater depth D2 in the direction perpendicular to the flow direction of the overflowed sealant, so that buffering can be achieved more effectively.

[0061] As shown in Figures 5 to 10, in some embodiments of the present application, the cross-section of the first groove 1310 is designed to be arc-shaped. When the back panel 1200 and the flange 1150 jointly extrude the sealant, the sealant will flow. The cross-section of the first groove 1310 is designed to be arc-shaped. In the process of the sealant overflowing from the first groove 1310, it is more conducive to the sealant filling the first groove 1310, avoiding the formation of bubbles, thereby improving the sealing effect.

[0062] The present application also discloses a dishwasher, which includes the inner tank 1000 of the above embodiment. The inner tank 1000 of the dishwasher of this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0063] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made based on the contents of the present application specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present application.
