Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to an inner liner and a dishwasher having the same. Background Technology

[0002] A typical dishwasher inner tub usually consists of a back panel and a frame. When assembling the back panel and frame, a welding and sealant application method is usually used to ensure connection strength and prevent leakage. In existing technology, when the back panel and frame are connected, the back panel and frame together compress the sealant, causing it to seep out from inside the inner tub. This uneven seepage reduces the quality of the dishwasher and requires excessive sealant application, resulting in high sealant consumption. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes an inner liner that not only effectively reduces the amount of sealant used, thereby effectively reducing costs, but also effectively reduces the amount of sealant overflowing into the inner liner, thus effectively improving the quality of the inner liner and the user experience.

The back panel is located on the rear side of the frame. A sealing area is provided on the side of the back panel facing the frame. The sealing area and the flange are bonded together with sealant. The opposing surfaces of the flange and / or the back panel form a first overflow groove and a second overflow groove. The first overflow groove and the second overflow groove are respectively arranged on both sides of the sealing area in the width direction of the flange and are suitable for accommodating sealant overflowing from the sealing area. This not only effectively reduces the amount of sealant used, thereby effectively reducing costs, but also allows the sealant to overflow into the first overflow groove and the second overflow groove after the frame and the back panel are bonded together, thereby effectively reducing the amount of sealant overflowing into the inner liner, and thus effectively improving the quality of the inner liner and the user experience.

[0008] In some embodiments, both the first and second overflow grooves are formed on the side surface of the back plate facing the flange.

[0009] In some embodiments, the first overflow groove and the second overflow groove are respectively located at the ends of the flange in the width direction.

[0010] In some embodiments, in the width direction of the flange, the first overflow groove is arranged on one side of the sealing area facing the outer periphery of the back plate, and the edge of the flange near the outer periphery of the back plate is a first edge, which extends to the front of the opening of the first overflow groove.

[0011] In some embodiments, the outer periphery of the back panel is formed with a first folded edge that bends forward, the first folded edge forming a sidewall of the first glue overflow groove on the side away from the frame.

[0012] In some embodiments, in the width direction of the flange, the second overflow groove is arranged on the side of the sealing area away from the outer periphery of the back plate. In a projection plane perpendicular to the front-back direction, the projection of the second overflow groove is located within the projection range of the flange.

[0014] In some embodiments, the flange is welded to the back plate at the location of the glue groove.

[0015] In some embodiments, the sealing area, the first overflow groove, and the second overflow groove all extend in a ring shape along the circumference of the back plate.

[0016] The dishwasher according to the second aspect of the present invention includes the inner tub according to the first aspect of the present invention.

[0017] According to the second aspect of this utility model, by setting the inner liner of the first aspect, the amount of sealant used can be effectively reduced, thereby effectively reducing costs. Furthermore, after the frame and back panel are bonded together, the sealant overflows into the first overflow groove and the second overflow groove, thereby effectively reducing the amount of sealant overflowing into the inner liner, and thus effectively improving the quality of the dishwasher and the user experience.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] The following is for reference. Figures 1-5 The inner liner 100 according to a first aspect embodiment of the present utility model is described.

[0031] like Figures 1-3 As shown, the inner liner 100 according to the first aspect of the present invention includes: a frame 10 and a back panel 20.

[0032] The frame 10 extends in the front-to-back direction, and the rear end of the frame 10 is provided with a flange 11; the back plate 20 is provided on the rear side of the frame 10, and the side surface of the back plate 20 facing the frame 10 is provided with a sealing area 21, and the sealing area 21 and the flange 11 are bonded together by sealant; wherein, the opposing surfaces of the flange 11 and / or the back plate 20 are formed with a first overflow groove 22 and a second overflow groove 23, the first overflow groove 22 and the second overflow groove 23 are respectively arranged on both sides of the sealing area 21 in the width direction of the flange 11, and are suitable for receiving sealant overflowing from the sealing area 21.

[0033] In some specific examples, such as Figure 1 and Figure 2 As shown, the frame 10 has an upper side plate 12, a lower side plate 13, a left side plate 14, and a right side plate 15. The upper side plate 12, lower side plate 13, left side plate 14, and right side plate 15 together enclose the frame 10. The frame 10 extends in the front-back direction. A flange 11 is provided at the rear end of the frame 10. One end of the flange 11 is connected to the frame 10, and the other end of the flange 11 extends in a direction away from the frame 10. Furthermore, the flange 11 is provided in the circumferential direction at the rear end of the frame 10 and extends in a ring shape along the circumferential direction at the rear end of the frame 10. The rear side of the flange 11 is bonded to the sealing area 21 on the front side of the back plate 20 by sealant.

[0034] For example, the side of the flange 11 facing the back panel 20 avoids forming a first glue overflow groove 22 and a second glue overflow groove 23; another example is that the surface of the back panel 20 facing the flange 11 has a first glue overflow groove 22 and a second glue overflow groove 23; yet another example is that the surface of the flange 11 facing the back panel 20 has one of the first glue overflow groove 22 and the second glue overflow groove 23, and the surface of the back panel 20 facing the flange 11 has the other of the first glue overflow groove 22 and the second glue overflow groove 23. Further, such as... Figure 3 As shown, the first overflow groove 22 and the second overflow groove 23 are respectively arranged on both sides of the sealing area 21 in the width direction of the flange 11. Thus, when assembling the back plate 20 and the frame 10, the flange 11 and the sealing area 21 of the back plate 20 can squeeze the sealant, so that the sealant overflows into the first overflow groove 22 and the second overflow groove 23 on both sides of the sealing area 21 along the width direction of the flange 11.

[0035] It should be noted that in the prior art, a glue groove 25 is usually set on the back panel 20, and an excessive amount of sealant is injected into the glue groove 25. This results in a large amount of glue used, high cost, and the overflowing sealant can be seen from the inside of the inner liner 100, which affects the appearance of the inner liner 100 and thus affects the user's experience.

[0036] In this embodiment, the sealing area 21 is the sealant application location. Compared to injecting excessive sealant into the sealant tank 25, applying sealant to the sealing area 21 can effectively reduce the amount of sealant used. After applying sealant, the sealing area 21 of the flange 11 and the back plate 20 can squeeze the sealant, causing the sealant to overflow into the first overflow groove 22 and the second overflow groove 23 on both sides of the sealing area 21 along the width direction of the flange 11. The amount of sealant overflowing into the first overflow groove 22 and the second overflow groove 23 is small, thereby effectively reducing the amount of sealant overflowing into the inner liner 100.

[0037] According to the embodiment of the present invention, the inner liner 100 includes a frame 10 and a back panel 20. The frame 10 extends in the front-to-back direction, and a flange 11 is provided at the rear end of the frame 10. The back panel 20 is located on the rear side of the frame 10, and a sealing area 21 is provided on the side of the back panel 20 facing the frame 10. The sealing area 21 and the flange 11 are bonded together with sealant. A first overflow groove 22 and a second overflow groove 23 are formed on the opposing surfaces of the flange 11 and / or the back panel 20. The first overflow groove... The groove 22 and the second overflow groove 23 are respectively arranged on both sides of the sealing area 21 in the width direction of the flange 11, and are suitable for accommodating the sealant overflowing from the sealing area 21. This not only effectively reduces the amount of sealant used, thereby effectively reducing costs, but also allows the sealant to overflow into the first overflow groove 22 and the second overflow groove 23 after the frame 10 and the back panel 20 are bonded together, thereby effectively reducing the amount of sealant overflowing into the inner liner 100, and thus effectively improving the quality of the inner liner 100 and the user's experience.

[0038] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the first overflow groove 22 and the second overflow groove 23 are both formed on the side surface of the back plate 20 facing the flange 11.

[0039] In some specific examples, such as Figure 2 and Figure 3 As shown, a first overflow groove 22 and a second overflow groove 23 are provided on the front side of the back plate 20, and the sealing area 21 is located between the first overflow groove 22 and the second overflow groove 23. Having both the first overflow groove 22 and the second overflow groove 23 on the front side of the back plate 20 facilitates their processing.

[0040] Specifically, the back plate 20 and the frame 10 are two different components with different shapes and / or sizes. If the first overflow groove 22 is set in one of the back plate 20 and the flange 11, and the second overflow groove 23 is set in the other of the back plate 20 and the flange 11, then the corresponding first overflow groove 22 and second overflow groove 23 need to be processed for the back plate 20 and the flange 11 respectively, and therefore different equipment is required.

[0041] In this embodiment, the first overflow groove 22 and the second overflow groove 23 are simultaneously disposed on the back plate 20, requiring only the back plate 20 to be processed, thus making it more convenient and faster. In particular, most of the frame 10 and the back plate 20 are sheet metal parts, and the first overflow groove 22 and the second overflow groove 23 can be formed by stamping the back plate 20, thereby simplifying the processing flow and improving production efficiency.

[0042] Furthermore, providing a first overflow groove 22 and a second overflow groove 23 on the front side of the back panel 20 can effectively reduce the difficulty of production. Specifically, when the first overflow groove 22 and / or the second overflow groove 23 are set on the flange 11 of the frame 10, the first overflow groove 22 and / or the second overflow groove 23 need to be machined on the flange 11. The flange 11 is much smaller than other parts of the frame 10 and presents a certain angle. Therefore, it is more difficult to machine the first overflow groove 22 and / or the second overflow groove 23 on the flange 11. In particular, when the frame 10 is a sheet metal part, the flange 11 is formed by bending part of the sheet metal part. At this time, the flange 11 is roughly perpendicular to other parts of the frame 10, which greatly increases the difficulty of machining the first overflow groove 22 and / or the second overflow groove 23 on the flange 11.

[0043] Therefore, in this embodiment, the first overflow groove 22 and the second overflow groove 23 are disposed on the back plate 20. The back plate 20 is generally in the form of a flat plate, so it is more convenient to process the first overflow groove 22 and the second overflow groove 23 on the back plate 20. Compared with processing the first overflow groove 22 and / or the second overflow groove 23 on the flange 11, processing the first overflow groove 22 and the second overflow groove 23 on the back plate 20 will greatly reduce the production difficulty, which is conducive to improving production efficiency and reducing production costs.

[0044] In this embodiment, by forming both the first overflow groove 22 and the second overflow groove 23 on the side surface of the back plate 20 facing the flange 11, the processing difficulty of the first overflow groove 22 and the second overflow groove 23 can be effectively reduced, making the processing of the first overflow groove 22 and the second overflow groove 23 easier, thereby effectively improving production efficiency and reducing production costs.

[0045] In one embodiment of this utility model, such as Figure 2 and Figure 3As shown, the first overflow groove 22 and the second overflow groove 23 are respectively located at the ends of the flange 11 in the width direction.

[0046] In some specific examples, such as Figure 2 and Figure 3 As shown, the first overflow groove 22 and the second overflow groove 23 are respectively located at the ends of the flange 11 in the width direction, and the first overflow groove 22 and the second overflow groove 23 are arranged at intervals. That is to say, the first overflow groove 22 and the second overflow groove 23 are respectively located on the back plate 20 area corresponding to the ends of the flange 11 in the width direction. This allows the sealant to be evenly distributed on the sealing area 21, ensuring the bonding strength between the sealing area 21 of the back plate 20 and the flange 11, and preventing sealing failure caused by uneven distribution of sealant.

[0047] In this embodiment, by setting the first overflow groove 22 and the second overflow groove 23 at the ends of the flange 11 in the width direction, the positions of the first overflow groove 22 and the second overflow groove 23 can be effectively optimized, so that the sealant is evenly distributed on the sealing area 21, ensuring the bonding strength between the sealing area 21 of the back plate 20 and the flange 11, preventing sealing failure caused by uneven distribution of sealant, thereby effectively improving the reliability of the bonding between the sealing area 21 and the flange 11.

[0048] In one embodiment of the present invention, as shown in 3, in the width direction of the flange 11, the first overflow groove 22 is arranged on the side of the sealing area 21 facing the outer periphery of the back plate 20, and the edge of the flange 11 near the outer periphery of the back plate 20 is the first edge 111, which extends to the front of the groove opening of the first overflow groove 22.

[0049] In some specific examples, such as Figure 3 As shown, the first overflow groove 22 is arranged on the front side of the back plate 20 and is located on the side of the sealing area 21 facing the outer periphery of the back plate 20. The edge of the flange 11 near the outer periphery of the back plate 20 is the first edge 111. The first edge 111 extends to the front of the groove opening of the first overflow groove 22 on the side facing the outer periphery of the back plate 20. Thus, the first edge 111 can guide or block the sealant overflowing from the sealing area 21.

[0050] Specifically, the first edge 111 extends to the front of the opening of the first overflow groove 22, which can guide the sealant overflowing from the sealing area 21 to overflow in the direction of the first edge 111. When the sealant overflows to the front of the opening of the first overflow groove 22, the sealant can overflow into the first overflow groove 22 due to the blocking effect of the first edge 111. Even if there is a slight deviation in assembly, it can ensure that the sealant is correctly introduced into the first overflow groove 22.

[0051] Furthermore, after the flange 11 of the frame 10 is bonded to the sealing area 21 of the back panel 20, since the first overflow groove 22 is connected to the external space, it is convenient to perform glue replenishment operation in the first overflow groove 22, thereby further improving the reliability and sealing of the bonding between the flange 11 of the frame 10 and the sealing area 21 of the back panel 20.

[0052] In this embodiment, in the width direction of the flange 11, the first overflow groove 22 is arranged on the side of the sealing area 21 facing the outer periphery of the back plate 20. The edge of the flange 11 near the outer periphery of the back plate 20 is the first edge 111. Extending the first edge 111 to the front of the groove opening of the first overflow groove 22 can effectively guide the sealant overflowing from the sealing area 21 to the first overflow groove 22, thereby effectively improving the reliability of the connection between the flange 11 and the sealing area 21.

[0053] In one embodiment of this utility model, such as Figure 3 As shown, the outer periphery of the back panel 20 has a first folded edge 24 that bends forward, and the first folded edge 24 forms the side wall of the first glue overflow groove 22 on the side away from the frame 10.

[0054] In some specific examples, such as Figure 3 As shown, the first folded edge 24 extends forward and then bends and extends towards the frame 10. Thus, the first folded edge 24, the back plate 20, and the first edge 111 of the flange 11 together form the sidewall of the first overflow groove 22. The first folded edge 24 can not only effectively improve the structural strength of the outer periphery of the back plate 20, but also effectively prevent the sealant overflowing into the first overflow groove 22 from leaking out of the first overflow groove 22.

[0055] In this embodiment, the outer periphery of the back panel 20 is formed into a first folded edge 24 that is bent forward. The first folded edge 24 constitutes the side wall of the first overflow groove 22 away from the frame 10. This not only effectively improves the structural strength of the outer periphery of the back panel 20, thereby effectively improving the reliability of the back panel 20, but also blocks the sealant in the first overflow groove 22, thereby effectively preventing the sealant overflowing into the first overflow groove 22 from leaking out of the first overflow groove 22, thus effectively improving the reliability of the first overflow groove 22.

[0056] In one embodiment of this utility model, such as Figure 3 As shown, in the width direction of the flange 11, the second overflow groove 23 is arranged on the side of the sealing area 21 away from the outer periphery of the back plate 20. In the projection plane perpendicular to the front and rear direction, the projection of the second overflow groove 23 is located within the projection range of the flange 11. The frame 10 and the back plate 20 cooperate to enclose the receiving cavity, and the second overflow groove 23 communicates with the receiving cavity.

[0057] In some specific examples, such as Figure 3As shown, the second overflow groove 23 is disposed on the side surface of the back plate 20 facing the flange 11, and the second overflow groove 23 is formed by the back plate 20 protruding backward. Furthermore, the second overflow groove 23 is arranged between the first overflow groove 22 and the receiving cavity, and the second overflow groove 23 communicates with the receiving cavity, thereby facilitating the overflow of sealant from the sealing area 21 into the second overflow groove 23.

[0058] In the projection plane perpendicular to the front-back direction, the projection of the second overflow groove 23 is located within the projection range of the flange 11. In other words, when there is sealant in the second overflow groove 23, the user cannot observe the overflowing sealant from the front-back direction, thereby effectively improving the user experience.

[0059] In this embodiment, the second overflow groove 23 is arranged on the side of the sealing area 21 away from the outer periphery of the back plate 20 in the width direction of the flange 11. In the projection plane perpendicular to the front and rear direction, the projection of the second overflow groove 23 is set within the projection range of the flange 11. The frame 10 and the back plate 20 cooperate to form a receiving cavity. The second overflow groove 23 is connected to the receiving cavity, so that the second overflow groove 23 can effectively contain the sealant overflowing from the sealing area 21 and prevent the user from observing the sealant in the second overflow groove 23 during use, thereby effectively improving the user experience.

[0060] In one embodiment of this utility model, such as Figure 4 and Figure 5 As shown, the sealing area 21 has a glue groove 25, which is filled with sealant.

[0061] For example, a glue groove 25 is formed on the surface of the flange 11 facing the back panel 20; similarly, a glue groove 25 is formed on the surface of the back panel 20 facing the flange 11. In some specific examples, such as Figure 4 and Figure 5 As shown, a glue groove 25 is formed on the side surface of the back plate 20 facing the flange 11. Furthermore, the glue groove 25 is located on the rear side of the flange 11 and is disposed opposite to the flange 11 in the front-rear direction. The glue groove 25 is formed by the back plate 20 protruding rearward, and the glue groove 25 is located between the first glue overflow groove 22 and the second glue overflow groove 23.

[0062] When assembling the back panel 20 and the frame 10, sealant is filled into the glue groove 25. The glue groove 25 provides a clear application space for the sealant, which not only effectively ensures that the sealant between the back panel 20 and the flange 11 is evenly distributed and firmly bonded, but also ensures that the amount of sealant used is appropriate. Excess sealant can overflow from the glue groove 25 into the first overflow groove 22 and the second overflow groove 23.

[0063] Furthermore, the glue tank 25 and the first overflow glue tank 22 are arranged alternately, and the glue tank 25 and the second overflow glue tank 23 are arranged alternately, thereby enabling the sealant to better fill the glue tank 25. Specifically, before assembling the back plate 20 and the frame 10 together, a fluid sealant needs to be applied to the glue tank 25. During the application process, due to the construction process, the sealant may not completely fill the glue tank 25, for example, air bubbles may form in some locations.

[0064] In this embodiment, the glue groove 25 is designed to be spaced apart from the first overflow groove 22 and the second overflow groove 23. This allows the sealant to first fill the glue groove 25 during the bonding process between the back plate 20 and the flange 11. Then, some of the sealant overflows into the first overflow groove 22 and the second overflow groove 23 under pressure. In other words, the sealant first fills the glue groove 25 and then overflows into the first overflow groove 22 and the second overflow groove 23, thereby effectively improving the sealing effect.

[0065] In this embodiment, by forming a glue groove 25 in the sealing area 21 and filling the glue groove 25 with sealant, the amount of sealant used can be effectively controlled and the sealant distribution between the back plate 20 and the flange 11 can be ensured to be uniform, thereby effectively improving the connection quality and connection strength between the back plate 20 and the flange 11.

[0066] In one embodiment of this utility model, such as Figure 5 As shown, the cross-section of the glue groove 25 is arc-shaped.

[0067] In some specific examples, such as Figure 5 As shown, the cross-section of the adhesive groove 25 is arc-shaped. Designing the cross-section of the adhesive groove 25 as arc-shaped facilitates the flow of the sealant within the groove 25 when the back plate 20 and the flange 11 jointly compress the sealant. During this flow, the sealant gradually fills the groove 25, preventing air bubble formation and effectively improving the filling quality. Furthermore, the arc-shaped groove 25 effectively increases the bonding area between the back plate 20 and the flange 11, thereby increasing the bonding strength between them and further improving the sealing effect.

[0068] In this embodiment, the cross-section of the glue groove 25 is set to be arc-shaped, which not only facilitates the flow of sealant in the glue groove 25, allowing the sealant to quickly fill the glue groove 25 and thus effectively improve the filling quality of the sealant in the glue groove 25, but also effectively increases the bonding area between the back plate 20 and the flange 11, thereby effectively increasing the bonding strength between the back plate 20 and the flange 11, and thus effectively improving the sealing effect.

[0069] In one embodiment of this utility model, the flange 11 and the back plate 20 are welded together at the position of the glue groove 25.

[0070] In some specific examples, both the back panel 20 and the frame 10 are sheet metal parts. After the flange 11 is bonded to the back panel 20 with sealant, they are then connected by welding at the curved surface of the glue groove 25. This effectively improves the connection strength between the back panel 20 and the flange 11, thereby enhancing durability. Furthermore, the first glue overflow groove 22 and the second glue overflow groove 23 are formed by stamping, which simplifies the processing flow and ensures the structural strength of the first glue overflow groove 22 and the second glue overflow groove 23.

[0071] In this embodiment, the flange 11 and the back plate 20 are welded together at the position of the glue groove 25, which can effectively improve the connection strength between the back plate 20 and the flange 11, thereby effectively improving the durability of the connection between the back plate 20 and the flange 11, and thus effectively extending the service life of the inner liner 100.

[0072] In one embodiment of the present invention, the sealing area 21, the first overflow groove 22 and the second overflow groove 23 all extend in a ring shape along the circumference of the back plate 20.

[0073] It should be noted that the annular sealing area 21, the first overflow groove 22, and the second overflow groove 23 extending circumferentially along the back plate 20 can achieve an all-around sealing effect, avoiding leakage problems caused by poor local sealing. Furthermore, the annular structure has greater adaptability to assembly errors, reducing the risk of seal failure due to assembly errors, thereby further improving the reliability of the sealing connection between the back plate 20 and the flange 11. In addition, the annular sealing area 21 extending circumferentially along the back plate 20 can effectively increase the bonding area between the back plate 20 and the flange 11, thereby effectively reducing the risk of bonding failure caused by excessive local stress.

[0074] In this embodiment, the sealing area 21, the first overflow groove 22, and the second overflow groove 23 all extend in a ring shape along the circumference of the back plate 20. This not only achieves a comprehensive sealing effect but also effectively reduces the risk of seal failure caused by assembly errors, thereby effectively improving the reliability of the seal. Furthermore, it effectively increases the bonding area between the back plate 20 and the flange 11, thereby effectively reducing the risk of bonding failure caused by excessive local stress, and thus effectively improving the bonding strength between the back plate 20 and the flange 11.

[0075] The dishwasher according to a second aspect of the present invention includes the inner liner 100 according to the first aspect of the present invention described above. In a specific example, the dishwasher includes a dish rack and a spray arm, which are disposed within a receiving cavity. Dishes are placed on the dish rack. When the dishes need to be washed, water jets from the spray arm are directed at the dishes on the dish rack. The water then falls back to the bottom of the receiving cavity and is subsequently circulated away and transported to the spray arm, thereby achieving cyclic cleaning of the dishes.

[0076] The inner liner 100 generally has a square structure, including a back panel 20 and a frame 10. The back panel 20 is connected to the rear side of the frame 10, so that the back panel 20 and the frame 10 are connected to form a receiving cavity. The front side of the frame 10 is open and communicates with the receiving cavity. The front side of the frame 10 can be opened and closed by the dishwasher door. When the dishwasher door is open, the dishes can be put into the receiving cavity. When the dishwasher door is closed, the dishes can be washed.

[0077] The frame 10 has a flange 11 located on the rear side of the frame 10, for example Figure 1 As shown, the frame 10 includes an upper side panel 12, a lower side panel 13, a left side panel 14, and a right side panel 15. The upper side panel 12 is located on top of the left side panel 14 and the right side panel 15, and the lower side panel 13 is located at the bottom of the left side panel 14 and the right side panel 15. For example, the upper side panel 12, the lower side panel 13, the left side panel 14, and the right side panel 15 can be four parts connected together by a connecting means. Alternatively, the upper side panel 12, the lower side panel 13, the left side panel 14, and the right side panel 15 can be formed by bending the same piece of sheet metal. In some specific examples, the upper side panel 12, the lower side panel 13, the left side panel 14, and the right side panel 15 all have flanges 11.

[0078] According to the present invention, by setting the inner liner 100 of the first aspect, the dishwasher can not only effectively reduce the amount of sealant used, thereby effectively reducing costs, but also allow the sealant to overflow into the first overflow groove 22 and the second overflow groove 23 after the frame 10 and the back panel 20 are bonded together, thereby effectively reducing the amount of sealant overflowing into the inner liner 100, and thus effectively improving the quality of the dishwasher and the user experience.
