Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0041] See also Figures 1-13In one embodiment of the dishwasher proposed by the present invention, a dishwasher inner tank includes: an inner tank body 10 made of stainless steel, a sealing flange 20 is provided on the top of the inner tank body 10, and an inner cover (not shown in the figure) for sealing the upper opening of the inner tank. The inner cover can be opened and closed to seal the inner tank with the sealing flange 20; when the dishwasher is in operation, the inner cover is closed and sealed with the sealing flange 20 to prevent water droplets in the inner tank from splashing out and water vapor from overflowing.

[0042] See also Figure 13 As shown, a spray chamber 227 connected to the dishwasher's water circuit is provided within the sealing flange 20. The spray chamber 227 is provided with a plurality of nozzles 2271 for spraying into the inner liner body 10. The spray water can be sprayed directly from the nozzles 2271, or a nozzle can be installed at the nozzles 2271. Providing the spray chamber 227 within the sealing flange 20 facilitates spraying the spray water from the top of the inner liner body 10, allowing spraying of the inner edge area of ​​the inner liner, thereby improving cleaning efficiency. Furthermore, the spray chamber 227 is disposed within the sealing flange 20, eliminating the need to occupy space within the inner liner, thereby ensuring the effective volume of the inner liner. Furthermore, the location of the spray chamber 227 within the sealing flange 20 allows the spray water to be sprayed from the sealing flange 20 to rinse the dishes and ultimately reach the bottom of the inner liner body. This means that the spray water has a longer spraying stroke, thereby improving the cleaning effect of the spray water.

[0043] In order to increase the spraying area, the spray chamber 227 is provided with a spray bottom wall 2272 which is tilted downward in the inward direction, and the nozzle 2271 is provided on the spray bottom wall 2272; so that the spray direction of the water flow ejected from the nozzle 2271 is downward and inward, and the angle between the spray bottom wall 2272 and the horizontal plane is 30° to 45°, so that the spray water flow has an inward spray angle. In order to ensure the spraying intensity and the need to spray the edge area of ​​the inner tank, the tilt angle of the spray bottom wall 2272 is not too large, and it is preferred to set the angle between the spray bottom wall 2272 and the horizontal plane to 30°.

[0044] See also Figure 3 As shown, the sealing flange 20 includes a sealing frame 21 integrally provided with the inner tank body 10 and a support frame 22 for supporting the sealing frame 21. By providing the support frame 22, it is beneficial to increase the structural strength of the sealing frame 21. When the inner cover applies a certain pressure to the supporting sealing frame 21 to ensure sealing, it is beneficial to ensure the force-bearing capacity of the sealing frame 21.

[0045] The support frame 22 comprises a support body 220, on which is disposed an upwardly extending spray cavity wall 2273. The spray cavity wall 2273 and the surrounding support body 220 form a spray lower shell. A spray cover 2274 is sealed to the upper end of the spray lower shell. The spray lower shell and the spray cover 2274 surround and form a spray cavity 227. The spray cavity wall 2273, sealed and secured to the support body 220, forms the spray cavity 227. Positioning the spray cavity 227 on the support frame 22 occupies the internal space of the sealing flange 20 and avoids the need for a separate spray cavity.

[0046] Regarding the installation and fixation of the support frame 22, the support frame 22 is engaged and fixed between the inner wall of the liner body 10 and the sealing frame 21, which is conducive to the convenience of the support frame 22 assembly operation and the sealing performance of the liner, avoiding the use of fasteners such as screws. The outer end of the support frame 22 is in contact with the inner wall of the liner body 10, and the outer end wall of the spray chamber 227 is located at the outer end of the support frame 22. The spray chamber 227 is adjacent to the inner wall of the liner body 10, which is conducive to the outward arrangement of the spray chamber 227 and the spray coverage around the liner. A notch 225 is provided at the inner end of the support frame 22 for mounting in conjunction with the sealing frame 22; that is, the outer end wall of the spray chamber 227 is in contact with the inner wall of the liner body 10, and the notch 225 at the inner end of the support frame 22 is engaged with the sealing frame 21, avoiding the need for fastening operations and facilitating increased installation efficiency. The support frame 22 is provided to seal the sealing frame 21 and prevent water droplets from entering the sealing frame 21.

[0047] The support body 220 includes a first support body 2201 disposed horizontally, and a second support body 2202 disposed outwardly and downwardly along the outer end of the first support body 2201. The downwardly inclined second support body 2202 is advantageous in increasing the height of the first support portion 224, increasing the contact area between the support frame 22 and the inner wall of the liner body 1, and increasing the stability of the support frame 22 after assembly. The spray chamber wall 2273 is disposed on the second support body 2202, that is, the spray bottom wall 2272 is part of the second support body 2202. The inclined second support body 2202 is also advantageous in facilitating the arrangement of the spray chamber 227. The angle between the second support body 2202 and the first support body 2201 is preferably set to 135° to 150°.

[0048] See also Figure 10-13As shown, the structure of the sealing frame 21 is explained. The opening end of the inner liner body 10 extends upward and then bends inward to form the sealing frame 21, so that the sealing frame 21 and the metal inner liner body 10 are arranged as one piece, avoiding the assembly, fixation and sealing between the sealing frame 21 and the inner liner body 10, which is beneficial to reducing the difficulty of process manufacturing; and since the sealing frame 21 is formed by extending and bending between the upper ends of the inner liner body 10, that is, the inner liner body 10 and the sealing frame 21 can be stamped and welded from a piece of steel plate, there is definitely no gap between the sealing frame 21 and the inner liner body 10, which ensures the sealing between the sealing frame 21 and the inner liner body 10; the sealing frame 21 is made of the same metal material as the inner liner body, which is beneficial to increase the structural strength of the inner liner, and avoids the easy adhesion of scale and vegetable residue caused by long-term use of plastic materials, thereby ensuring the washing effect and cleaning rate.

[0049] The liner body 10 and the sealing frame 21 are preferably made of a piece of steel plate. The sealing frame 21 is a square frame. The corners of the sealing frame 21 are the connection points of two adjacent sealing edges. The two adjacent sealing edges are formed by extending upward along the two adjacent side walls and bending inward. The two adjacent side walls are formed by bending the steel plate, and two sealing edges are formed by extending upward along the upper ends of the two side walls and bending inward. That is, the lower ends of the two adjacent sealing edges intersect, which causes welding deformation and stress concentration to easily occur in the welding near the intersection, seriously affecting the welding quality, and the two sealing edges are not easy to weld at the bend, and it is not easy to polish after welding, which is time-consuming and labor-intensive and cannot guarantee quality; therefore, an opening 211 is provided at the corner of the sealing frame 21, and a decorative block 25 for filling the opening 211 is provided at the opening 211. By setting the opening 211, welding at the intersection of the two adjacent sealing edges can be avoided, and welding at the bend is avoided, thereby ensuring welding quality and improving manufacturing efficiency.

[0050] The sealing frame 21 has an extension portion 212 extending upward along the inner liner body 10, a bent portion 213 inward along the upper end of the extension portion 212, and a first platform portion 214 extending inward along the bent portion 213. The extension portion 212, the bent portion 213 and the first platform portion 214 are all frame-shaped, and the opening 211 is opened at the corners of the extension portion 212 and the bent portion 213.

[0051] The sealing frame 21 also includes a first connecting portion 215 that bends downward and inward along the inner end of the first platform portion 214, and a second platform portion 216 that extends inward along the inner end of the first connecting portion 215. The first platform portion 214 and the second platform portion 216 are arranged parallel to each other. The sealing strip on the inner lid of the dishwasher seals against the second platform portion 216. The stepped arrangement of the first and second platforms 214 and 216 prevents water droplets dripping onto the second platform portion 216 from spilling outward and facilitates the sealing and positioning of the inner lid and the sealing frame 21. To maximize the height of the spray chamber 227, the height below the first platform portion 214 is highest within the sealing flange 20, and therefore the spray chamber 227 is located below the first platform portion 214.

[0052] The sealing frame 21 also has a third platform portion 218 located below the second platform portion 216 and a second connecting portion 217 for connecting the second platform portion 216 and the third platform portion 218. The third platform portion 218 is arranged parallel to the second platform portion 216, and the second connecting portion 217 is semicircular. The second connecting portion 217 is conducive to forming a smooth end surface on the inner side of the sealing frame 21, which is conducive to the operation of removing and placing tableware from the inner pot body 10, and is conducive to increasing the structural strength of the sealing frame 21 and improving the aesthetic appearance. The provision of the third platform portion 218 further increases the structural strength of the sealing frame 21 and facilitates the fixation of the support frame 22.

[0053] The ratio of the inner-outer dimension of the second platform portion 216 to the inner-outer dimension of the first platform portion 214 is 2 to 3, and preferably the ratio is set to 2. The ratio of the inner-outer dimension of the second platform portion 216 to the inner-outer dimension of the third platform portion 218 is 2 to 3, and preferably the ratio is set to 2.5.

[0054] The inner end of the support frame 22 is provided with a notch 225 that mates with the outer end of the third platform portion 218. This allows the first support portion 224 on the outer end of the support frame 22 to rest against the inner wall of the liner body 10. The notch 225 on the inner end of the support frame 22 engages with the outer end of the third platform portion 218. This allows the support frame 22 to be fixed between the inner wall of the liner body 10 and the third platform portion 218, eliminating the need for fastening and improving installation efficiency. The lower end surface of the first support body 2201 is flush with the lower end surface of the third platform portion 218, and the outer end of the first support body 2201 is located directly below the first connecting portion 213.

[0055] In order to increase the support of the support frame 22 for the sealing frame 21, a second support portion 226 extending upward is provided along the inner end of the support body 221. The second support portion 226 approaches and contacts the first platform portion 214 to support the first platform portion 214, thereby increasing the ability of the first platform portion 214 to withstand downward force and ensuring the strength of the first platform portion 214.

[0056] See also Figure 3-Figure 8 As shown, the structure of the decorative block 25 is described. The decorative block 25 is installed and fixed on the support frame 22. The support frame 22 has the function of supporting the sealing frame 21 and also has the function of fixing the decorative block 25, which is beneficial to increase the firmness of the fixing of the decorative block 25.

[0057] The decorative block 25 has a fan-shaped decorative body 251, a tie plate 252 extending inward along the decorative body 251, and a tie head 253 for fixation provided along the inner end of the tie plate 252. The tie head 253 extends along the inner end of the tie plate 252 in the thickness direction of the tie plate 252, and the thickness direction of the tie plate 252 is perpendicular to the inner and outer directions; wherein the decorative body 251 is located at the opening 211, and the opening 211 is a fan-shaped opening that is narrow inside and wide outside. The decorative block 25 is also fan-shaped that is narrow inside and wide outside, so the decorative block 25 needs to be installed from the outside to the inside at the opening 211.

[0058] The tie head 253 has two symmetrically extending tie claws 2531. The support frame 22 is provided with two engaging openings 221 that match the tie claws 2531. The tie claws 2531 are located within the engaging openings 221. The tie claws 2531 and the engaging openings 221 restrict the inward and outward movement of the tie head 253, ensuring secure fixation. The tie head 253 has a curved inner end surface 2532 that abuts against the spray chamber wall 2273 of the spray chamber 227. The spray chamber wall 2273 forms the inner end wall of the engaging opening 221. After the decorative block 25 is installed and fixed, the arc-shaped inner end surface 2532 contacts the spray cavity wall 2273 to prevent the decorative block 25 from moving inward; the decorative body 251 has a horizontally arranged bottom end surface that matches the bottom surface of the opening 211, and the decorative body 251 has two vertical end surfaces that are close to each other in the inward direction; the decorative body 251 is located at the opening 211, and the decorative body 251 is fan-shaped with a narrow inside and a wide outside. The size of the outer end of the decorative body 251 is larger than the size of the opening 211, that is, the distance between the outer ends of the two vertical end surfaces of the decorative body 251 is greater than the width of the opening 211, so that when the decorative block 25 moves inward from the opening 211, the two vertical end surfaces of the decorative block 25 are blocked by the opening 211. Preferably, the outer end surface of the decorative block 25 is flush with the sealing frame 21 at the opening 211.

[0059] The support frame 22 comprises a plate-shaped support body 220, on which are disposed two symmetrically arranged second stopper members 223 connected to the spray chamber wall 2273. The adjacent sides of the two second stopper members 223 form engaging openings 221 with the spray chamber wall 2273. The symmetrical arrangement of the two tie claws 2531 and the two engaging openings 221 facilitates securing both ends of the tie head 253, facilitating force balance on the tie head 253 and increasing stability after securing.

[0060] The two sides of the second retaining members 223 that face away from each other are respectively connected to the spray chamber wall 2273, which helps increase the structural strength of the second retaining members 223 and enhances the stability of the fixing of the tie head 253. To install the decorative block 25, the decorative block 25 must be moved inward from the opening 211 so that the tie head 253 is positioned above the engaging opening 221. The decorative block 25 must then be moved downward so that the tie head 253 engages within the engaging opening 221, positioning the decorative body 251 within the opening 211. In other words, the height of the decorative body 251 must be greater than the height of the tie head 253 to ensure proper assembly of the decorative block 25.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein with equivalents.
