Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to a dishwasher inner container and a dishwasher. Background Art

[0002] At present, in some dishwashers, the inner tank of the dishwasher is composed of a back plate and an annular frame, wherein the annular frame is formed by connecting a plurality of plates in sequence, and a flange is formed at one end (rear end) of the annular frame, and the back plate is connected to the flange, thus forming the inner tank of the dishwasher. However, such an inner tank may have the risk of water leakage. Summary of the invention

[0003] The main purpose of the present invention is to provide a dishwasher inner tank, aiming to reduce the risk of water leakage in the dishwasher inner tank.

[0004] To achieve the above-mentioned purpose, the dishwasher liner proposed by the present invention comprises:

[0005] An annular frame body, comprising at least two plates connected in sequence, wherein the connection between two adjacent plates forms a connecting portion, one end of the annular frame body is provided with a flange, and the connecting portion has a folded section located at the flange; and

[0006] A back plate is connected to the flange, the back plate is provided with an air avoidance groove corresponding to the folding section, and a sealant is provided between the air avoidance groove and the folding section.

[0007] By providing an air avoidance groove corresponding to the folded section on the back panel and filling sealant between the air avoidance groove and the folded section, the connection sealing between the annular frame and the back panel is improved, the risk of water leakage between the annular frame and the back panel is reduced, the sealing of the inner liner is better, and the risk of water leakage of the inner liner is reduced.

[0008] Optionally, the orthographic projection of the folded section on the back plate is located in the air avoidance groove.

[0009] In this way, any deformation at any position on the folding section can be accommodated in the air-avoiding groove, thereby reducing the possibility that the deformed part of the folding section abuts against the edge of the notch of the air-avoiding groove.

[0010] Optionally, the outer end of the folded section is spaced apart from the outer edge of the air avoiding groove.

[0011] By setting the outer end of the folded section and the outer edge of the air avoidance groove at a distance, even if the folded section is elongated due to errors or deformation of the folded section, the air avoidance groove can better accommodate the folded section, thereby reducing the possibility of the outer end of the folded section abutting the outer edge of the air avoidance groove.

[0012] Optionally, the distance between the outer end of the folded section and the outer edge of the air avoiding groove is not less than 3 mm and not more than 6 mm.

[0013] This not only reduces the risk of the outer end of the folded section abutting against the outer edge of the air-avoiding groove, but also helps to reduce the size of the back plate.

[0014] Optionally, with the width direction of the flange as the length direction of the air avoidance groove and the folding section, the ratio of the groove width of the air avoidance groove to the width of the folding section is not less than 1.5 and not greater than 3.

[0015] It is ensured that when the portion of the flange adjacent to the folded section is deformed along with the folded section, the air-avoiding groove can better accommodate the deformed portion.

[0016] Optionally, the ratio of the width of the avoidance groove to the width of the folding section is not less than 2 and not greater than 2.5.

[0017] In this way, while ensuring that the air-avoiding groove can better accommodate the portion of the flange adjacent to the folded section, the connection stability between the back plate and the flange can also be improved.

[0018] Optionally, the air avoidance groove has a first groove bottom wall and two first groove side walls arranged on two opposite sides of the first groove bottom wall, the first groove bottom wall is arranged opposite to the groove opening of the air avoidance groove, and the first groove side wall is arranged at an angle to the first groove bottom wall.

[0019] This makes the plastic deformation at the connection between the first groove side wall and the first groove bottom wall large, the springback after forming is small, the shape is easy to maintain, the size is relatively easy to control, and the flatness of the back panel can be improved, thereby ensuring smooth contact between the flange and the back panel, which is beneficial to improving the sealing between the flange and the back panel.

[0020] Optionally, the outer end of the folded section is covered with sealant.

[0021] This can prevent the water in the inner tank from flowing along the gaps between the stacked structures in the folded section and flowing out from the outer end of the folded section, further reducing the risk of water leakage in the inner tank.

[0022] Optionally, two adjacent panels are connected by a bite to form the connecting portion, and the connecting portion is formed with a connecting seam extending along its length direction.

[0023] This ensures that the connection between two adjacent panels is reliable and has good sealing performance.

[0024] Optionally, a glue-containing groove is recessed on the back plate at a corner formed by the annular frame and the flange, the glue-containing groove is annular and extends along the circumference of the annular frame, and sealant is filled between the glue-containing groove and the enclosure.

[0025] During the welding process, the sealant can be filled between the glue groove and the enclosure, thereby further improving the sealing between the annular frame and the back plate and further reducing the risk of water leakage in the liner.

[0026] Optionally, an inner edge of the glue containing groove is located inside the annular frame and is spaced apart from an inner surface of the annular frame.

[0027] In this way, during the process of pressing the flange and the back panel, excess sealant can overflow evenly from the overflow gap, reducing the risk of undesirable phenomena such as glue overflow and glue breakage, and reducing the scrap rate of the inner liner caused by undesirable phenomena such as glue overflow and glue breakage in the glue groove.

[0028] Optionally, the distance between the inner surface of the annular frame and the inner edge of the glue containing groove is not less than one third of the width of the glue containing groove, and not more than two thirds of the width of the glue containing groove.

[0029] In this way, a larger gap can be ensured for glue overflow between the inner edge of the glue groove and the annular frame, and the sealant can overflow evenly when the back panel and the flange are welded, thereby avoiding undesirable phenomena such as glue overflow and glue breakage. The scrap rate of the inner liner caused by undesirable phenomena such as glue overflow and glue breakage can be reduced from 5%-10% to 0%.

[0030] Optionally, the air-avoiding groove is communicated with the glue-containing groove.

[0031] In this way, the sealant can flow between the air avoidance groove and the glue containing groove, so that the sealant can be set on the air avoidance groove and the glue containing groove at the same time. There is no need to apply sealant to the air avoidance groove and the glue containing groove separately, which can improve production efficiency.

[0032] Optionally, the glue containing groove has a second groove bottom wall and two second groove side walls arranged on two opposite sides of the second groove bottom wall, the second groove bottom wall is arranged opposite to the groove opening of the glue containing groove, and the second groove side wall is arranged at an angle to the second groove bottom wall.

[0033] This makes the plastic deformation at the connection between the second groove side wall and the second groove bottom wall large, the springback after forming is small, the shape is easy to maintain, the size is relatively easy to control, and the flatness of the back panel can be improved, thereby ensuring smooth contact between the flange and the back panel, which is beneficial to improving the sealing between the flange and the back panel.

[0034] Optionally, the plurality of panels are respectively two opposite first panels and two opposite second panels, the first panels and the second panels are alternately connected; the connecting portion comprises a first inlay panel and a second inlay panel, the first inlay panel is arranged on a side of the first panel and is spaced from an outer surface of the first panel to form a first inlay groove, the second inlay panel is arranged on a side of the second panel and is spaced from an inner surface of the second panel to form a second inlay groove, the first inlay panel is embedded in the second inlay groove, and the second inlay panel is embedded in the first inlay groove.

[0035] This can ensure that the connection between two adjacent panels is reliable and the sealing is good. When an air avoidance groove is set on the back plate, even if the folded section is deformed, the air avoidance groove can better accommodate the deformed part of the folded section, thereby enhancing the sealing between the flange and the back plate.

[0036] The present invention further provides a dishwasher, an outer shell and a dishwasher inner container as described above, wherein the dishwasher inner container is arranged in the outer shell.

[0037] The technical solution of the present invention is to provide an air-avoiding groove at a position corresponding to the folding section on the back plate. In this way, even if the folding section forms a bulge on one side of the back plate, the bulged part of the folding section will be accommodated in the air-avoiding groove. Thereby, the bulge formed on the folding section is avoided from abutting against the back plate, so as to ensure that the rest of the flange can be in relatively flat contact with the back plate, reduce the gap between the rest of the flange and the back plate, and reduce the risk of water leakage caused by the gap between the flange and the back plate after welding. By providing a sealant in the air-avoiding groove, when the flange is welded to the back plate, the sealant can be filled between the folding section and the back plate, thereby preventing water from flowing out of the inner liner through the air-avoiding groove. Moreover, it can prevent water from flowing from the gap of the folding section to the two opposite sides in the width direction of the folding section, thereby preventing the water in the inner liner from flowing from the gap of the folding section to the gap between the rest of the flange and the back plate. That is, this solution provides an air avoidance groove on the corresponding folded section of the back panel, and fills sealant between the air avoidance groove and the folded section, thereby improving the sealing of the connection between the annular frame and the back panel, reducing the risk of water leakage between the annular frame and the back panel, making the inner liner more sealed and reducing the risk of water leakage of the inner liner.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is 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.

[0053] The invention provides an inner container of a dishwasher.

[0054] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The dishwasher inner tank 100 includes an annular frame 10, including at least two plates 11 connected in sequence, the connection between two adjacent plates 11 forms a connecting portion 12, one end of the annular frame 10 is provided with a flange 13, and the connecting portion 12 has a folding section 121 located at the flange 13. The back plate 20 is connected to the flange 13, and the back plate 20 is provided with an air avoidance groove 21 corresponding to the folding section 121, and a sealant (not shown) is provided between the air avoidance groove 21 and the folding section 121.

[0055] In this embodiment, the number of the plates 11 can be two, three, four, five, six or more, etc., wherein the plates 11 can be in the shape of a straight plate, a bent plate or an arc plate, etc. In addition, it should be noted that the number of the connecting portion 12 is at least one. For example, when the number of the plates 11 is two, one side of one of the plates 11 is integrally formed with the other plate 11, and the other side forms a connecting portion 12 with the other plate 11, which is equivalent to the two plates 11 being integrally formed, and the sides of the two plates 11 that are far away from each other are connected to form a connecting portion 12. Of course, the plates 11 can also be evenly divided, and the connection between any two adjacent plates 11 forms a connecting portion 12.

[0056] In practical applications, a plurality of plates 11 are usually connected in sequence to form an annular frame 10, and then one end of the annular frame 10 is folded outward to form a flange 13. At this time, the connecting portion 12 is also folded together, so that when the flange 13 is formed, the portion of the connecting portion 12 that is bent to form the flange 13 is the folding section 121, that is, the folding section 121 is also part of the flange 13. For ease of explanation, the width direction of the flange 13 is taken as the length direction of the air avoidance groove 21 and the folding section 121.

[0057] The connection part 12 is usually formed by two plates 11 being connected by a bite or by two plates 11 being overlapped and welded, which results in the thickness of the connection part 12 being greater than the thickness of the plate 11. When the flange 13 is folded, the folded section 121 may have a large rebound, and the stacked structures in the folded section 121 may be separated from each other, which will cause the folded section 121 to form a bulge on one side of the back plate 20. Furthermore, when the flange 13 is welded to the back plate 20, the bulged part of the folded section 121 will first abut against the back plate 20, resulting in a larger gap between the rest of the flange 13 (the part outside the folded section 121 on the flange 13) and the back plate 20, increasing the risk of a gap between the flange 13 and the back plate 20 after welding, resulting in poor sealing of the dishwasher inner tank 100 and easy water leakage.

[0058] In view of this, the technical solution of the present invention is to provide an air-avoiding groove 21 at the position corresponding to the folding section 121 on the back plate 20. In this way, even if the folding section 121 forms a bulge toward one side of the back plate 20, the bulged part of the folding section 121 will be accommodated in the air-avoiding groove 21. This avoids the situation where the bulge formed on the folding section 121 abuts against the back plate 20, so as to ensure that the rest of the flange 13 can be in relatively flat contact with the back plate 20, reduce the gap between the rest of the flange 13 and the back plate 20, and reduce the risk of water leakage caused by the gap between the flange 13 and the back plate 20 after welding. By providing a sealant in the air-avoiding groove 21, when the flange 13 is welded to the back plate 20, the sealant can be filled between the folding section 121 and the back plate 20, thereby preventing water from flowing out of the dishwasher inner tank 100 through the air-avoiding groove 21. Moreover, it can prevent water from flowing from the gap of the folded section 121 toward the two opposite sides in the width direction of the folded section 121, thereby preventing water in the dishwasher inner tank 100 from flowing from the gap of the folded section 121 to the space between the remaining part of the flange 13 and the back plate 20. That is, the present solution provides an air avoidance groove 21 on the back plate 20 corresponding to the folded section 121, and fills the space between the air avoidance groove 21 and the folded section 121 with sealant, thereby improving the connection sealing between the annular frame 10 and the back plate 20, reducing the risk of water leakage between the annular frame 10 and the back plate 20, making the dishwasher inner tank 100 more sealed, and reducing the risk of water leakage in the dishwasher inner tank 100.

[0059] Due to the influence of molding process and error, after forming the flange 13, the bulge formed by the deformation of the folding section 121 may be different. Therefore, in order to ensure that the air-avoiding groove 21 can better accommodate the deformed part of the folding section 121, please refer to Figures 2 to 4In one embodiment, the orthographic projection of the folded section 121 on the back plate 20 is located in the air-avoiding groove 21. That is, the size of the air-avoiding groove 21 is greater than or equal to the size of the folded section 121, so that any deformation at any position on the folded section 121 can be accommodated in the air-avoiding groove 21, reducing the possibility that the deformed part of the folded section 121 abuts against the edge of the notch of the air-avoiding groove 21. Of course, in other embodiments, only the orthographic projection of part of the structure of the folded section 121 on the back plate 20 may be located in the air-avoiding groove 21, for example, only the orthographic projection of the outer end of the folded section 121 and the part close to the outer end on the back plate 20 is located in the air-avoiding groove 21, etc.

[0060] In one embodiment, the outer end of the folded section 121 is spaced apart from the outer edge of the air-avoiding groove 21. Specifically, in the process of forming the flange 13, there is usually an error. If the length of the air-avoiding groove 21 is set to be roughly equal to the length of the folded section 121, after forming the flange 13, the length of the folded section 121 may be greater than the length of the air-avoiding groove 21, causing the outer end of the folded section 121 to extend outward from the air-avoiding groove 21 and abut against the outer edge of the air-avoiding groove 21. By setting the outer end of the folded section 121 apart from the outer edge of the air-avoiding groove 21, even if the folded section 121 is extended due to an error or deformation of the folded section 121, the air-avoiding groove 21 can better accommodate the folded section 121, thereby reducing the possibility that the outer end of the folded section 121 abuts against the outer edge of the air-avoiding groove 21. Of course, in other embodiments, the outer end of the folded segment 121 may also be flush with the outer edge of the air avoiding groove 21 , that is, the outer end of the folded segment 121 is flush with the groove side wall of the air avoiding groove 21 .

[0061] When the outer end of the folded section 121 is spaced from the outer edge of the air-avoiding groove 21, if the interval between the two is too large, the size of the back plate 20 needs to be increased to provide a setting space for the air-avoiding groove 21, which will cause the outer size of the back plate 20 and even the inner tank 100 of the dishwasher to be too large, which is not conducive to improving the compactness of the dishwasher structure. If the gap between the two is too small, the risk of the outer end of the folded section 121 abutting against the outer edge of the air-avoiding groove 21 will increase. Therefore, in order to take into account both the size of the back plate 20 and the risk of the outer end of the folded section 121 abutting against the outer edge of the air-avoiding groove 21, in one embodiment, the distance between the outer end of the folded section 121 and the outer edge of the air-avoiding groove 21 is not less than 3 mm and not more than 6 mm. That is, in the length direction of the folded section 121, the distance between the outer end of the folded section 121 and the outer edge of the air-avoiding groove 21 is greater than or equal to 3 mm and less than or equal to 6 mm. Specifically, the distance between the outer end of the folded section 121 and the outer edge of the air-avoiding groove 21 can be 3 mm, 4 mm, 5 mm or 6 mm, etc. Of course, in other embodiments, the distance between the outer end of the folded section 121 and the outer edge of the air-avoiding groove 21 can also be less than 3 mm, or greater than 6 mm.

[0062] In one embodiment, two adjacent panels 11 are connected by a bite to form a connecting portion 12, and the connecting portion 12 is formed with a connecting seam 126 extending along its length direction (see Figure 4 and Fig. 9 ). That is, the sealant between the air-avoiding groove 21 and the folding section 121 can be filled in the connection seam 126. When two adjacent panels 11 are connected by the bite, it can ensure that the connection between the two adjacent panels 11 is reliable and has good sealing. The connecting portion 12 can be a single bite structure, a combined angle bite structure, a corner bite structure, a vertical bite structure, or an edge bite structure, etc.

[0063] To further improve the sealing performance of the folded section 121, in one embodiment, the outer end of the folded section 121 is covered with a sealant (see Figure 2 The dotted area referred to by the “sealant area” in the figure). That is, after the flange 13 is welded to the back plate 20, a sealant is provided at the outer end of the folded section 121 to seal the gap (connecting seam 126) at the outer end of the folded section 121, thereby preventing the water in the dishwasher inner tank 100 from flowing along the gap (connecting seam 126) between the stacked structures (connecting portion 12) in the folded section 121 and flowing out from the outer end of the folded section 121, thereby further reducing the risk of water leakage in the dishwasher inner tank 100. Moreover, when the outer end of the folded section 121 is spaced from the outer edge of the air avoidance groove 21, the sealant at the outer end of the folded section 121 can also be combined with the sealant in the air avoidance groove 21, so that the folded section 121 can be better wrapped, thereby improving the sealing between the folded section 121 and the back plate 20.

[0064] In addition, since the space between the air-avoiding groove 21 and the folding section 121 is filled with sealant, it can prevent water from flowing from the gap of the connecting portion 12 toward the two opposite sides of the folding section 121 in the width direction. Therefore, it is not necessary to set sealant on the outside of the rest of the flange 13 for waterproofing. It is only necessary to set sealant on the outer end of the folding section 121, which reduces the process of filling the entire circumference of the flange 13, can reduce the process time by about 40 seconds, and greatly improves production efficiency. At the same time, it can reduce the amount of sealant used, which is conducive to saving resources and reducing costs. Of course, in other embodiments, the outer end of the folding section 121 may not be provided with sealant, and other methods may be used for sealing.

[0065] In one embodiment, the width direction of the flange 13 is the length direction of the air-avoiding groove 21 and the folding section 121, and the ratio of the groove width of the air-avoiding groove 21 to the width of the folding section 121 is not less than 1.5 and not greater than 3. Specifically, in the width direction of the folding section 121, the two groove side walls of the air-avoiding groove 21 are spaced from the two sides of the width direction of the folding section 121, that is, the orthographic projection of the folding section 121 on the back plate 20 is spaced from the two groove side walls of the air-avoiding groove 21, and the groove width of the air-avoiding groove 21 is at least 1.5 times the width of the folding section 121, and at most 3 times the width of the folding section 121. This ensures that when the portion of the flange 13 adjacent to the folding section 121 is deformed along with the folding section 121, the air-avoiding groove 21 can also better accommodate the deformed portion. In one embodiment, the spacing between the side edges of the folded section 121 in the width direction and the corresponding side walls of the air-avoiding groove 21 is roughly the same, so as to ensure that the air-avoiding groove 21 can better accommodate the folded section 121 and the deformed part adjacent to the folded section 121. In addition, when the air-avoiding groove 21 is wider, the contact area between the sealant and the flange 13 can be increased, thereby increasing the path for water to flow from the folded section 121 along the width direction to the rest of the flange 13 and the back plate 20, further reducing the risk of water leakage. Of course, in other embodiments, the side edges of the folded section 121 in the width direction can also be flush with the side walls of the air-avoiding groove 21.

[0066] Among them, if the slot width of the air-avoiding groove 21 is too large, the sealing effect of the sealant is increased less, and the amount of sealant in the air-avoiding groove 21 needs to be increased, resulting in unnecessary waste, and the welding position between the flange 13 and the back plate 20 will be reduced, reducing the connection reliability between the back plate 20 and the flange 13. If the slot width of the air-avoiding groove 21 is too small, the risk of the part of the flange 13 adjacent to the folding section 121 abutting against the edge of the air-avoiding groove 21 when deformed will be increased. Therefore, in order to have both the connection stability between the back plate 20 and the flange 13 and the air-avoiding groove 21 to better accommodate the part of the flange 13 adjacent to the folding section 121, in one embodiment, the ratio of the slot width of the air-avoiding groove 21 to the width of the folding section 121 is not less than 2, and not greater than 2.5. Of course, in other embodiments, the ratio of the slot width of the air-avoiding groove 21 to the width of the folding section 121 can also be less than 2, or greater than 2.5.

[0067] In one embodiment, the air-avoiding groove 21 has a first groove bottom wall and two first groove side walls respectively arranged on two opposite sides of the first groove bottom wall, the first groove bottom wall is arranged opposite to the notch of the air-avoiding groove 21, and the first groove side wall is arranged at an angle with the first groove bottom wall. The two first groove side walls are distributed in the width direction of the air-avoiding groove 21, that is, the cross-sectional area of ​​the air-avoiding groove 21 perpendicular to its length direction is roughly trapezoidal or rectangular, compared with the arc-shaped manner of the air-avoiding groove 21, so that the plastic deformation of the connection between the first groove side wall and the first groove bottom wall is large, the rebound amount after forming is small, the shape is easy to maintain, the size is relatively easy to control, and the flatness of the back plate 20 can be improved, thereby ensuring the flat contact between the flange 13 and the back plate 20, which is conducive to improving the sealing between the flange 13 and the back plate 20. Of course, in other embodiments, the two first groove side walls are distributed in the length direction of the air-avoiding groove 21.

[0068] Please refer to Figure 5 and Figure 6 In one embodiment, the back plate 20 is provided with a glue groove 22 at the corner formed by the annular frame 10 and the flange 13, and the glue groove 22 is annular and extends along the circumference of the annular frame 10, and a sealant (not shown) is filled between the glue groove 22 and the enclosure. Specifically, the glue groove 22 is in a closed ring shape. When assembling the dishwasher liner 100, a sealant greater than the capacity of the glue groove 22 is first set in the glue groove 22, and then the flange 13 is welded to the back plate 20. In the welding process, the sealant can be filled between the glue groove 22 and the enclosure, so that the sealing between the annular frame 10 and the back plate 20 can be further improved, and the risk of water leakage in the dishwasher liner 100 can be further reduced. Of course, in other embodiments, the glue groove 22 may not be provided.

[0069] Since the amount of sealant is relatively large, the sealant is likely to overflow from the gap between the flange 13 and the back plate 20 during the process of pressing the flange 13 and the back plate 20. If the flange 13 completely covers the notch of the glue-containing groove 22, during the process of welding the back plate 20 and the flange 13, the sealant will be compressed and squeezed out from the tiny gap between the back plate 20 and the flange 13, which is prone to undesirable phenomena such as glue overflow and glue breakage, thereby increasing the scrap rate of the dishwasher liner 100. To reduce the above risks, in one embodiment, the inner edge of the glue-containing groove 22 is located on the inner side of the annular frame 10 and is spaced from the inner surface of the annular frame 10. Specifically, in the width direction of the glue groove 22, the inner edge of the glue groove 22 is spaced apart from the inner side of the annular frame 10, that is, there is a glue overflow gap between the inner edge of the glue groove 22 and the annular frame 10, so that in the process of pressing the flange 13 and the back plate 20, the excess sealant can be evenly overflowed from the glue overflow gap, reducing the risk of undesirable phenomena such as glue overflow and glue breakage, and reducing the scrap rate of the dishwasher inner tank 100 caused by undesirable phenomena such as glue overflow and glue breakage in the glue groove 22. Of course, in other embodiments, the inner edge of the glue groove 22 is roughly flush with the inner surface of the annular frame 10.

[0070] In order to ensure that the sealant overflows more evenly, in one embodiment, the distance between the inner surface of the annular frame 10 and the inner edge of the glue groove 22 is not less than one-third of the width of the glue groove 22, and not more than two-thirds of the width of the glue groove 22. That is, in the width direction of the glue groove 22, the distance between the inner surface of the annular frame 10 and the inner edge of the glue groove 22 is not less than one-third of the width of the glue groove 22, and not more than two-thirds of the width of the glue groove 22. In other words, the distance between the inner surface of the annular frame 10 and the orthographic projection of the inner edge of the glue groove 22 on the surface of the back plate 20 is not less than one-third of the width of the glue groove 22, and not more than two-thirds of the width of the glue groove 22. In this way, it is possible to ensure that the gap between the inner edge of the glue groove 22 and the annular frame 10 is large, and the sealant can evenly overflow when the back plate 20 is welded to the flange 13, which can avoid the occurrence of undesirable phenomena such as glue flipping and glue breaking, so that the scrap rate of the dishwasher inner tank 100 caused by undesirable phenomena such as glue flipping and glue breaking can be reduced from 5%-10% to 0%. Of course, in other embodiments, the distance between the inner surface of the annular frame 10 and the inner edge of the glue groove 22 can also be less than one-third of the width of the glue groove 22, or greater than two-thirds of the width of the glue groove 22.

[0071] Please refer to Figure 7 and Figure 8In one embodiment, the air-avoiding groove 21 is connected to the glue-containing groove 22. In this way, the sealant can flow between the air-avoiding groove 21 and the glue-containing groove 22, so that the air-avoiding groove 21 and the glue-containing groove 22 can be provided with sealant at the same time, and there is no need to apply sealant to the air-avoiding groove 21 and the glue-containing groove 22 separately, which can improve production efficiency. Moreover, the sealants in the air-avoiding groove 21 and the glue-containing groove 22 are connected to each other, which can increase the contact area with the flange 13, which is beneficial to improving the waterproof performance. Of course, in other embodiments, the air-avoiding groove 21 and the glue-containing groove 22 can also be spaced apart.

[0072] Please refer to Figure 6 In one embodiment, the adhesive groove 22 has a second groove bottom wall 222 and two second groove side walls 221 disposed on two opposite sides of the second groove bottom wall 222. The second groove bottom wall 222 is disposed opposite to the notch of the adhesive groove 22, and the second groove side wall 221 is disposed at an angle to the second groove bottom wall 222. That is, the cross-sectional area of ​​the adhesive groove 22 perpendicular to its length direction is roughly trapezoidal or rectangular. Compared with the arc-shaped adhesive groove 22, the plastic deformation at the connection between the second groove side wall 221 and the second groove bottom wall 222 is large, the rebound amount after forming is small, the shape is easy to maintain, the size is relatively easy to control, and the flatness of the back plate 20 can be improved, thereby ensuring the flat contact between the flange 13 and the back plate 20, which is conducive to improving the sealing between the flange 13 and the back plate 20.

[0073] Please refer to Figure 1 , Figure 2 and Fig. 9 In one embodiment, the plurality of panels 11 are respectively two opposite first panels 111 and two opposite second panels 112, the first panels 111 and the second panels 112 are alternately connected, the connecting portion 12 includes a first panel 122 and a second panel 123, the first panel 122 is arranged on the side of the first panel 111, and is spaced from the outer surface of the first panel 111 to form a first embedded groove 124, the second panel 123 is arranged on the side of the second panel 112, and is spaced from the inner surface of the second panel 112 to form a second embedded groove 125, the first panel 122 is embedded in the second embedded groove 125, and the second panel 123 is embedded in the first embedded groove 124. That is, the first panel 122 and the second panel 123 are engaged with each other, and the connection portion 12 forms a bite structure, such as an inner flat bite structure, so that the first panel 122 and the inner wall surface of the second embedding groove 125 are closely matched, and the second panel 123 and the inner wall surface of the first embedding groove 124 are closely matched, so as to increase the bite strength and improve the sealing. When this structure is adopted, it can ensure that the connection between the two adjacent panels 11 is reliable and the sealing is good. When the air avoidance groove 21 is set on the back plate 20, even if the folding section 121 is deformed, the air avoidance groove 21 can better accommodate the deformed part of the folding section 121, thereby enhancing the sealing between the flange 13 and the back plate 20. Of course, in other embodiments, the connection portion 12 can also be other single bite structures.

[0074] In order to improve the sealing performance at the connection portion 12, in one embodiment, before the first plate 111 and the second plate 112 are engaged with each other, a sealant may be provided at the position where the first plate 111 and the second plate 112 are engaged with each other, so that after the engagement forms the connection portion 12, the space between the first panel 122 and the second panel 123, the space between the first panel 122 and the groove wall of the second groove 125, and the space between the second panel 123 and the groove wall of the first groove 124 are partially or completely filled with the sealant, thereby facilitating further improving the sealing performance of the inner tank.

[0075] The present invention further provides a dishwasher, which includes an outer shell and a dishwasher inner tank 100.
