Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and in particular relates to an inner tank structure of a dishwasher. Background Art

[0002] The inner tanks of existing dishwashers are mostly made of plastic injection molding. However, after a period of use, scale and other vegetable debris will accumulate on the inner surface of the plastic tank, directly affecting the washing effect and cleaning rate. The residual scale in the plastic tank also directly affects the drying performance of the dishwasher. As a solution to the above, stainless steel tanks are gradually being used in dishwashers, and their cleaning rate and drying performance are better than plastic tanks. However, since the stainless steel tanks need to be assembled with other parts by welding, the molding process of stainless steel tanks is complicated and not conducive to the integration of the tank components. Therefore, the development of a stainless steel tank with simpler components has been the direction of efforts of those skilled in the art.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0039] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0040] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0041] like Figures 1 to 6 As shown, the present invention discloses a dishwasher liner structure, which is particularly suitable for drawer-type dishwashers. The dishwasher also includes an outer shell for accommodating the dishwasher liner structure. The dishwasher liner structure includes an inner shell body 10 with an open top. The open end of the inner shell body 10 is provided with a first sealing structure and a second sealing structure. The first sealing structure is fixedly connected to the second sealing structure via a connecting structure to form an annular sealing structure. The first sealing structure is fixedly connected to the second sealing structure via a connecting structure to form an annular sealing structure, which makes the assembly of the annular sealing structure and the open end of the inner shell body 10 simpler and increases the assembly efficiency of the inner shell structure. At the same time, the sealing structure is avoided by welding the open end of the inner shell body 10, eliminating the welding process and preventing some hazards caused by welding. At the same time, the annular sealing structure is provided at the open end of the inner shell body 10 to effectively prevent water in the dishwasher inner shell body 10 from splashing out of the inner shell body and entering between the inner shell structure and the outer shell, thereby achieving a seal between the inner shell body 10 and the outer shell.

[0042] Specifically, the inner container body 10 includes a first side panel 11 and a second side panel 12 disposed opposite the first side panel 11. The first sealing structure is a flange structure 20 formed by bending the ends of the first side panel 11 and the second side panel 12. The second sealing structure is a connecting flange 21 disposed at the ends of the two side panels adjacent to the first side panel 11. The connecting structure includes a connecting portion 50 disposed at the end of the flange structure 20 adjacent to the inner container body 10, and an assembly portion disposed at the end where the connecting flange 21 connects to the flange structure 20 and mates with the connecting portion 50. By using the flange structure 20 formed at the ends of the first side panel 11 and the second side panel 12 of the dishwasher inner container body 10 as the first sealing structure, the processing steps of the sealing structure are reduced, saving processing materials.

[0043] As another embodiment of this embodiment, the flange structure 20 can also be formed by integral injection molding to prevent the inner wall of the liner body from being affected during the process of bending the first side panel and the second side panel to form the flange structure.

[0044] As an implementation method of this embodiment, the connecting structure can adopt a technical solution in which the connecting part 50 and the flange structure 20 are integrally formed, and the assembly part and the connecting flange 21 are integrally formed, thereby increasing the connection strength between the connecting part 50 and the flange structure 20, and the connection strength between the assembly part and the connecting flange 21; at the same time, it also eliminates the process of connecting the connecting structure to the flange structure 20 and the connecting flange 21 respectively, simplifies the assembly process, and increases the assembly efficiency of the dishwasher inner tank structure.

[0045] As another implementation of this embodiment, the connecting structure can also be provided separately from the flange structure 20 and the connecting flange 21. The connecting structure is fixedly connected to the flange structure 20 and the connecting flange 21 respectively, thereby achieving the purpose of fixed connection between the flange structure 20 and the connecting flange 21. This solution reduces the difficulty of manufacturing the flange structure 20 and the connecting flange 21, as well as the dimensional accuracy requirements of the flange structure 20 and the connecting flange 21. The dimensions of the connecting structure can be adjusted to accommodate slight changes in the dimensions of the flange structure 20 or the connecting flange 21.

[0046] The inner container structure is suitable for use in a drawer-type dishwasher. The dishwasher also includes an outer shell for accommodating the inner container structure. A sealing member is disposed within the outer shell. When the inner container structure is inserted into the outer shell, the sealing member contacts and seals with the inner container structure's sealing structure, preventing water from spilling out of the inner container structure. After the flange structure 20 and the connecting flange 21 are fixedly connected via the connecting portion 50 and the assembly portion, the upper surface of the flange structure 20 is flush with the upper surface of the connecting flange 21. This ensures a better seal between the sealing member and the flange structure 20, preventing water from spilling out of the inner container structure during dishwashing.

[0047] As an implementation method of this embodiment, a first snap-on portion is provided on the connecting portion, and a second snap-on portion is provided on the assembly portion. The flanging structure and the connecting flange are fixedly connected by the first snap-on portion on the connecting portion and the second snap-on portion on the assembly portion through the snap-on portion; the connecting flange 21 and the flanging structure 20 are fixedly connected by the snap-on portion, and there is no need to use other fasteners for connection and fixation, which makes assembly simpler.

[0048] Alternatively, the connecting portion and the assembly portion are both provided with connection holes, the connection holes on the connecting portion and the connection holes on the assembly portion being aligned, and bolts or screws passing through the connection holes to fasten the connecting portion and the assembly portion, thereby securing the flange structure and the connection flange. Standard bolts or screws are easier to purchase and the technology is more mature.

[0049] Alternatively, the connecting portion and the assembly portion are both provided with connecting holes, so that the ends of the connecting portion and the assembly portion are abutted and aligned, and the connecting holes on the connecting portion and the assembly portion are horizontally aligned, and a limiting buckle is used to limit and fix the connecting portion and the assembly portion, thereby fixing the flange structure and the connecting flange. Specifically, the limiting buckle includes a connecting portion and limiting posts extending downwardly from both ends of the connecting portion. The limiting buckle engages with the connecting holes to fix the connecting portion and the assembly portion.

[0050] As one implementation of this embodiment, the connecting portion 50 is formed by extending from the end of the flange structure 20 toward the side proximal to the connecting flange 21, and the assembly portion is formed by extending from the end of the connecting flange 21 toward the side proximal to the flange structure 20. Preferably, the connecting portion 50 is formed by extending from the bottom end of the flange structure 20, and the assembly portion is formed by extending from the top end of the connecting flange 21. The technical solution of integrally forming the connecting portion 50 with the flange structure 20 and the assembly portion with the connecting flange 21 increases the connection strength between the connecting portion 50 and the flange structure 20, and the assembly portion and the connecting flange 21. It also eliminates the need to separately connect the connecting structure to the flange structure 20 and the connecting flange 21, simplifying the assembly process and increasing the efficiency of assembling the dishwasher's inner tank structure. When the connecting flange 21 is connected to the flanging structure 20, the assembly part located on the connecting flange 21 must be moved to be assembled and connected with the connecting part 50 located on the flanging structure 20. Therefore, a technical solution is adopted in which the connecting part 50 is formed by extending from the bottom of the end of the flanging structure 20, and the assembly part is formed by extending from the top of the end of the connecting flange 21. That is, the assembly part is on the top and the connecting part 50 is on the bottom during the assembly connection, which makes it easier to assemble and connect the connecting flange 21 and the flanging structure 20.

[0051] As one implementation of this embodiment, the connecting portion 50 is formed by integrally extending the end of the flange structure 20 along its length, and the first clip portion is integrally arranged along the length of the connecting portion 50; the assembly portion is formed by integrally extending the end of the connecting flange 21 along its length, and the second clip portion corresponds to the first clip portion and is integrally arranged along the length of the assembly portion. The connecting portion 50 is integrally extended along its length by the end of the flange structure 20, and the assembly portion is integrally extended along its length by the end of the connecting flange 21. This increases the connection strength between the connecting portion 50 and the flange structure 20, and between the assembly portion and the connecting flange 21, preventing the connecting portion 50 and the flange structure 20 from disconnecting due to insufficient strength, or the assembly portion and the connecting flange 21 from disconnecting due to insufficient connection strength, which would cause the flange structure 20 and the connecting flange 21 to lose their fixation and move, thereby shortening the service life of the dishwasher's inner tank structure. The first clip part and the second clip part are respectively arranged as a whole along the length direction of the connecting part 50 and the length direction of the assembly part, increasing the connection strength between the first clip part and the connecting part 50, and the second clip part and the assembly part, thereby making the connection between the connecting part 50 and the assembly part more firm and reliable.

[0052] As another embodiment of this embodiment, the connecting portion 50 is formed as an integral extension of the end portion of the flange structure 20 along its length, and the first snap-on portions are spaced apart along the length of the connecting portion 50. The assembly portion is formed as an integral extension of the end portion of the connecting flange 21 along its length, and the second snap-on portions are spaced apart along the length of the assembly portion corresponding to the first snap-on portions. Specifically, the first snap-on portions are spaced apart along the length of the connecting portion 50, and the second snap-on portions are spaced apart along the length of the assembly portion. This allows the first snap-on portions and the second snap-on portions to be interlaced and secured together, thereby enhancing the securement and reliability of the snap-on fit.

[0053] As one implementation of this embodiment, the connecting portion 50 is formed by extending the end of the flange structure 20 at regular intervals along its length, with each connecting portion 50 being provided with a snap-on portion. The assembly portion is formed by extending the end of the connecting flange 21 as a whole along its length, with the two snap-on portions corresponding to the first snap-on portion being spaced apart along the length of the assembly portion. The connecting portion 50 is formed by extending the end of the flange structure 20 at regular intervals along its length, with each connecting portion 50 being provided with a snap-on portion. This saves material and allows each connecting portion 50 to be independently adjusted, reducing assembly difficulty. The assembly portion is formed by extending the end of the connecting flange 21 as a whole along its length, with the upper surface of the assembly portion shielding the assembly portion and the connecting portion 50, thereby protecting the appearance of the liner structure from the influence of the connecting structure.

[0054] Specifically, the first clip portion is a snap-fit ​​notch 51 provided on the connecting portion 50, and the second clip portion is a snap-fit ​​column provided on the assembly portion that cooperates with the snap-fit ​​notch 51. The snap-fit ​​connection method is used to snap-fit ​​the connecting flange 21 and the flange structure 20, eliminating the need for other fasteners for connection and fixation, making assembly simpler.

[0055] As an implementation method of this embodiment, the flange structure 20 includes a first bent portion formed by the end of the first side panel 11 and the end of the second side panel 12 bending toward the inner side of the inner tank body 10, and a second bent portion 201 formed by the free end of the first bent portion bending toward the outer side of the inner tank body 10, and the free end of the second bent portion 201 is bent upward and then bent horizontally to form a water retaining portion 203. The first bent portion bends toward the inner side of the inner tank body 10, forming a water retaining surface so that the water splashing out of the inner tank body 10 hits the water retaining surface and returns to the inner tank body 10, forming a sealing structure that serves as a first line of defense against water splashing outward from the inner tank body 10. The second bent portion 201 bends toward the outside of the inner tank, and the upper surface of the second bent portion 201 contacts and seals with a sealing component provided in the outer shell to form a second line of defense to further prevent water splashing out of the inner tank from splashing out of the dishwasher. The free end of the second bending portion 201 is bent upward and then horizontally to form a water retaining portion 203, so that the water retaining portion 203 is higher than the upper edge of the inner tank body 10. The water retaining portion 203 further blocks the water in the inner tank from splashing out of the dishwasher, preventing the water in the inner tank from slipping through the first and second lines of defense, thereby achieving a better sealing effect and improving the user experience.

[0056] As another implementation of this embodiment, the flange structure 20 includes a first bending portion formed by the end of the first side panel 11 and the end of the second side panel 12 being bent toward the inner side of the inner liner body 10, and a second bending portion 201 formed by the free end of the first bending portion being bent toward the outer side of the inner liner body 10, the free end of the second bending portion 201 being bent upward and then horizontally to form a third bending portion 202, and the free end of the third bending portion 202 being bent upward and then horizontally to form a water retaining portion 203. Furthermore, the second bending portion 201 and the third bending portion 202 are connected in an arc-shaped transition. The third bending portion 202 is provided and is higher than the second bending portion 201, so that the sealing surface formed by the upper surfaces of the second bending portion 201 and the third bending portion 202 forms a stepped surface. The contact area between the sealing surface and the sealing component is increased, thereby enhancing the sealing effect.

[0057] As an implementation method of this embodiment, the connecting flange 21 is integrally connected to the outer plate 30 on the side away from the inner liner body 10; it also includes a base 40, the inner liner body 10 is set on the base 40, and the outer plate 30 is fixedly connected to the base 40. The outer plate 30 and the connecting flange 21 are connected as one piece, eliminating the assembly process of the outer plate 30 and the connecting flange 21, thereby improving the assembly efficiency of the inner liner structure. The outer plate 30 is connected to the base 40 and the connecting flange 21 so that the base 40 and the connecting flange 21 are connected and fixed. At the same time, the inner liner body 10 is limited and fixed between the base 40 and the connecting flange 21, so that the base 40 can drive the inner liner to be pulled in and out of the outer shell, forming a drawer structure, which is convenient for assembly and simple in process. The resulting drawer device has high strength and good reliability. In addition, the setting of the outer plate 30 prevents the inner liner body 10 from being exposed, plays a role in beautifying the appearance, and can also protect the inner liner body 10.

[0058] Specifically, the inner container body 10, the connecting flange 21, and the outer plate 30 are made of different materials. Preferably, the inner container body 10 is made of metal, while the connecting flange 21 and the outer plate 30 are both made of plastic. Using plastic for the connecting flange 21 and the outer plate 30 significantly reduces the manufacturing cost of the dishwasher inner container structure and simplifies the manufacturing process of the inner container structure.

[0059] As an implementation of this embodiment, the inner liner body 10 also includes a third side panel 13 and a fourth side panel 14 adjacent to both the first side panel 11 and the second side panel 12, that is, the inner liner body 10 includes an annular structure formed by the first side panel 11, the second side panel 12, the third side panel 13, and the fourth side panel 14. The connecting flange 21 is provided with a mounting groove 210 on the side facing the inner liner body 10. The tops of the third side panel 13 and the fourth side panel 14 are inserted into the mounting groove 210 and fixedly connected to the connecting flange 21. In order to make the connection between the connecting flange 21 and the third side panel 13 and the fourth side panel 14 more firmly, a limiting structure is provided on the top of each of the third side panel 13 and the fourth side panel 14, and the limiting structure includes: a limiting platform 61 and a limiting folding edge 60. The end of the third side panel 13 and the end of the fourth side panel 14 outside the limiting platform 61 are bent toward the outside of the inner container body 10 and then bent upward. The limiting hem 60 is formed by bending the free end of the limiting platform 61 toward the outside of the inner container body 10. The mounting groove 210 is also provided with a limiting groove 211 that cooperates with the limiting hem 60. The limiting hem 60 is formed by bending the end of the third side panel 13 and the fourth side panel 14 toward the outside of the inner container and then bending downward to form an elastic gap, which makes the limiting hem 60 elastic. When the ends of the third side panel 13 and the fourth side panel 14 are connected and matched with the mounting groove 210 of the connecting flange 21, as the ends of the third side panel 13 and the fourth side panel 14 are inserted into the mounting groove 210, the limiting fold 60 is squeezed by the inner wall of the mounting groove 210 and elastically deformed. When the lower end of the limiting fold 60 enters the position of the limiting groove 211, the limiting fold 60 springs open under the action of the elastic restoring force, so that the limiting fold 60 and the inner wall of the limiting groove 211 are in contact with each other, and the lower end of the mounting groove 210 abuts against the limiting platform 61. The provision of the limiting platform 61 reduces the difficulty of assembly. The provision of the limiting fold 60 and the limiting groove 211 greatly increases the connection strength between the connecting flange 21 and the inner liner body 10, and increases the connection reliability between the connecting flange 21 and the inner liner body 10.

[0060] The inner liner structure also includes a door body, which is arranged on the outside of the first side panel 11. Specifically, the upper part of the door body is connected to the flange structure 20 formed by bending the end of the first side panel 11, and the lower part of the door body is connected to the outer wall of the base 40. The left and right sides of the door body are respectively fixedly connected to one side of the outer panel 30 close to the first side panel 11.

[0061] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
