The positioning section is connected to the end of the support section closest to the wall of the inner liner body and inserted into the first through-hole. This design allows the positioning section to be inserted into the first through-hole during assembly, allowing the inner liner body to support and position the fixed shaft. This also ensures the coaxiality of the first through-hole and the fixed shaft, eliminating the need for the assembler to manually hold the fixed shaft in alignment with the first through-hole. This facilitates subsequent fastener connection to the fixed shaft, further reducing assembly difficulty.

[0022] 4. The fastener is a screw integrally formed with the fixed shaft. The mounting portion has a second threaded hole, which the screw passes through the first through-hole and is threadedly connected to the second threaded hole. This design further reduces the number of components in the liner structure, thereby further reducing assembly complexity and making assembly more convenient. It also avoids the problem of assembly failure caused by lost fasteners.

[0023] 5. The wall of the inner tank body is provided with a positioning flange extending outwardly around the first through-hole. The mounting portion includes a positioning cover that is buckled onto the outside of the positioning flange and supported on the outer wall of the inner tank body. This design allows the positioning cover to be buckled onto the outside of the positioning flange during assembly, allowing the positioning flange to support and position the water tank, thereby ensuring the coaxiality of the mounting portion and the first through-hole. This eliminates the need for the assembler to manually hold the water tank to maintain alignment between the mounting portion and the first through-hole. This facilitates subsequent connection of fasteners to the mounting portion and the first through-hole, further reducing assembly difficulty.

[0024] 6. The mounting portion also includes a sink, a mounting post located on the bottom wall of the sink, and reinforcing ribs connecting the mounting post to the sink wall. The bottom wall of the sink forms a positioning cover, and fasteners connect the mounting post to the fixed shaft.

[0048] Example 1

[0049] like Figures 1 to 7As shown, the inner tank structure of the dishwasher in this embodiment includes an inner tank body 100, a guide roller 200 and a water tank 300, wherein the inner tank body 100 is provided with a washing chamber 110 for holding tableware, the guide roller 200 is provided in the washing chamber 110 and fixed on the left and right side walls of the inner tank body 100, and a bowl basket is also provided in the washing chamber 110, and the left and right sides of the bowl basket are supported on the guide rails equipped with the guide roller 200, and the guide rails are slidably connected to the guide roller 200, and the bowl basket is placed with tableware, and the bowl basket can be smoothly put in and out of the washing machine by pushing and pulling the bowl basket. The washing chamber 110, the guide roller 200 in this embodiment includes a fixed shaft 210 and a roller 220 rotatably mounted on the fixed shaft 210, which can drive the roller 220 to roll when pushing or pulling the bowl basket to reduce the pushing and pulling force; the water tank 300 is arranged on the outside of the inner container body 100 and has a mounting portion 310, and the wall of the inner container body 100 is provided with a first through hole 101. The fastener 400 passes through the first through hole 101 and connects the mounting portion 310 and the fixed shaft 210 to fix the water tank 300 and the guide roller 200 to the wall of the inner container body 100.

[0050] That is, the water tank 300 and the fixed shaft 210 of the guide roller 200 in this embodiment share a fastener 400 to be fixed to the inner tank body 100, that is, the water tank 300 is also fixed to the inner tank body 100 by utilizing the existing fastener 400 for fixing the fixed shaft 210, without adding an additional fastener 400, thereby reducing the number of parts of the inner tank structure, thereby reducing the assembly complexity, making the assembly more convenient, and also improving the assembly efficiency and production efficiency; in addition, this fixing method can also improve the installation reliability of the water tank 300, with better fixation, and the water tank will not be offset. After the water tank 300 is installed, the projection of the water tank 300 in the direction of the dishwasher base can be within the dishwasher base, thereby ensuring the embedded installation of the dishwasher in the kitchen cabinet or the assembly of the dishwasher shell and the base; finally, the inner tank body 100 does not need to be modified and can be matched with models with or without water tanks, saving the development cost of the entire machine.

[0051] like Figures 3 to 6As shown, in this embodiment, a first threaded hole 211 is provided on the fixed shaft 210, and a second through hole 311 is provided on the mounting portion 310. The fastener 400 is a screw, which includes a rod 410 and a head 420. The rod 410 passes through the second through hole 311 and the first through hole 101 in sequence and is threadedly connected to the first threaded hole 211. The head 420 abuts against the side of the mounting portion 310 away from the inner tank body 100, thereby allowing the guide roller 200 and the water tank 300 to be fixed to the inner tank body 100 at the same time by one fastener 400. In addition, the second through hole 311 in this embodiment does not need to be set as a threaded hole, thereby simplifying the processing difficulty of the mounting portion 310; furthermore, when the fastener 400 is damaged, the fastener 400 can be replaced separately, thereby reducing maintenance costs; finally, the head 420 is located on the outside of the inner tank body 100, which can prevent the head 420 from contacting the water in the inner tank body 100 and rusting and corroding, thereby further improving the installation reliability of the water tank 300.

[0052] The fixed shaft 210 in this embodiment includes a coaxially arranged support section 212 and a positioning section 213. The roller 220 is rotatably mounted on the support section 212. The positioning section 213 is connected to one end of the support section 212 close to the wall of the inner container body 100. The outer diameter of the positioning section 213 is smaller than the outer diameter of the support section 212, so that the fixed shaft 210 forms a stepped shaft. The first threaded hole 211 is provided on the positioning section 213. When the guide roller 200 is assembled to the inner container body 100, the positioning section 213 is inserted into the first through hole 101, and The end face of the support section 212 close to the positioning section 213 is against the inner side surface of the inner liner body 100. During assembly, the positioning section 213 can be first inserted into the first through hole 101, so that the inner liner body 100 can support and position the fixed shaft 210. At the same time, the coaxiality of the first through hole 101 and the fixed shaft 210 is also guaranteed. The assembler does not need to hold the fixed shaft 210 with his hands to keep it aligned with the first through hole 101, thereby facilitating the subsequent connection of the fastener 400 with the fixed shaft 210, thereby further reducing the difficulty of assembly.

[0053] In order to facilitate the screwing of the fastener 400 with the first threaded hole 211, the cross-section of the positioning section 213 in this embodiment is a non-circular cross-section, such as a D-shape, a waist shape, or a rectangle, etc. Correspondingly, the shape of the first through hole 101 is adapted to the cross-sectional shape of the positioning section 213, so as to prevent the fixed shaft 210 from rotating relative to the inner liner body 100. In this way, when the fastener 400 is screwed with the first threaded hole 211, the assembler does not need to hold the fixed shaft 210 to prevent it from rotating relative to the inner liner body 100, thereby further facilitating the assembly of the inner liner structure.

[0054] In addition, in order to facilitate the positioning of the water tank 300 and the inner container body 100, the wall portion of the inner container body 100 is provided with a positioning flange 102 formed by surrounding the first through hole 101 and extending outward, since the inner container body 100 is a metal piece, the first through hole 101 and the positioning flange 102 can be formed by stamping. The mounting portion 310 includes a positioning cover 312, which is buckled outside the positioning flange 102 and can be supported on the outer wall of the inner container body 100. In this way, during assembly, the positioning cover 312 can be buckled outside the positioning flange 102, so that the positioning flange 102 can support and position the water tank 300, thereby ensuring the coaxiality of the mounting portion 310 and the first through hole 101, and the assembler does not need to hold the water tank 300 with his hand to keep the mounting portion 310 and the first through hole 101 in alignment, thereby facilitating the connection of the fastener 400 with the mounting portion 310 and the first through hole 101, and further reducing the assembly difficulty.

[0055] The mounting portion 310 in the embodiment further includes a sink 313, a mounting column 314 and a reinforcing rib 315. The sink 313 is recessed from the side of the water tank 300 away from the inner container body 100 to the side of the water tank 300 close to the inner container body 100. The bottom wall of the sink 313 protrudes from the surface of the side of the water tank 300 close to the inner container body 100. The mounting column 314 is arranged on the bottom wall of the sink 313. The second through hole 311 is arranged through the mounting column 314 and the bottom wall of the sink 313, so as to connect the mounting column 314 and the fixing shaft 210 by the fastener 400. The reinforcing rib 315 is arranged between the mounting column 314 and the side wall of the sink 313. The mounting column 314 is connected with the side wall and the bottom wall of the sink 313. The bottom wall of the sink 313 is deformed and arched towards the direction of the sink opening, so as to form the positioning cover 312 on the bottom wall of the sink 313, thereby facilitating the processing and forming of the positioning cover 312. In addition, the arrangement of the reinforcing rib 315 also ensures the structural strength of the positioning cover 312 and the mounting column 314, and avoids deformation of the two.

[0056] It should be noted that after the fastener 400 is assembled, the head portion 420 is entirely located in the sink 313, that is, the head portion 420 does not protrude outward from the side of the water tank 300 away from the inner container body 100, thereby avoiding the risk of scratching the cabinet by the fastener 400 when the dishwasher is installed in the cabinet.

[0057] Secondly, as Figure 2 , Figure 5 and Figure 7As shown, to further improve the reliability of the connection between the water tank 300 and the inner liner body 100, the water tank 300 in this embodiment is provided with an elastic clip 320. The inner liner structure also includes a connecting plate 120 mounted on the outer wall of the inner liner body 100. The connecting plate 120 is provided with a snap-fit ​​hole 121, and the elastic clip 320 snaps into the snap-fit ​​hole 121. This design can play a dual role in fixing the water tank 300, not only further improving the fixing reliability of the water tank 300, but also ensuring relative fixing through the other fixing method if one fixing method fails.

[0058] Preferably, the connecting plate 120 is a U-shaped plate or an L-shaped plate. The connecting plate 120 is arranged near the bile opening of the inner tank body 100 and is located on the front side of the water tank 300. The connecting plate 120 includes a vertical plate arranged near the front side of the water tank 300. The snap-in hole 121 is arranged through the vertical plate front and back. An elastic snap 320 is provided on one side of the water tank 300 near the vertical plate, that is, an elastic snap 320 is provided on the front side of the water tank 300. The elastic snap 320 includes an elastic arm 321 extending forward and a card protrusion 322 provided at the end of the elastic arm 321. The elastic arm 321 is bent toward the wall of the inner tank body 100 to form a U-shaped structure. One end of the elastic arm 321 is fixedly connected to the water tank 300, and the other end is provided with the said card protrusion 322. The card protrusion 322 faces the back The latch 322 extends from one side of the inner tank body 100, and the front side surface of the latch 322 is an inclined surface that gradually approaches the inner tank body 100 forward. In this way, during assembly, when the water tank 300 is horizontally installed on the inner tank body 100 toward the inner side of the inner tank body 100, a little force can be applied to make the latch 322 smoothly snap into the snap-in hole 121 under the guidance of the inclined surface, and at the same time, the positioning cover 312 can also be snapped onto the positioning flange 102, thereby further reducing the difficulty of assembling the water tank 300; in addition, the elastic clip 320 can adapt to the gap between the water tank 300 and the vertical plate through the deformation of the elastic arm 321 to ensure the smooth snap-in connection between the latch 322 and the snap-in hole 121, thereby reducing the processing requirements of the elastic clip 320.

[0059] Finally, the inner tank structure of this embodiment further includes a water softener 500 disposed outside the inner tank body 100. The water softener 500 is connected to the water tank 300 and is located on the same side of the inner tank body 100. This design shortens the water path between the water softener 500 and the water tank 300 and makes the water path layout more reasonable.

[0060] It can be understood that in other embodiments of the present invention, the fasteners can also be bolts and nuts. The bolts pass through the second through hole, the first through hole and the entire fixed shaft and are locked and fixed with the nuts. Therefore, the water tank and the guide roller can also be fixed to the wall of the inner tank body through the fasteners.

[0061] It can be understood that in other embodiments of the present invention, the mounting portion is a groove provided on the water tank, the second through hole is provided on the bottom wall of the groove, the rod of the screw passes through the second through hole, the first through hole and the threaded hole on the fixed shaft in sequence and is threadedly connected, and the head of the screw is against the bottom wall of the groove and is located in the groove.

[0062] It can be understood that in other embodiments of the present invention, the inner side wall of the inner liner body can be provided with a positioning flange arranged around the first through hole by stamping, the fixed shaft sleeve is arranged on the positioning flange and fixed relative to the positioning flange in the circumferential direction, and the rod of the screw passes through the second through hole, the first through hole and the threaded hole on the fixed shaft in sequence.

[0063] It is understandable that in other embodiments of the present invention, the connecting plate can also be a horizontal plate arranged near the top of the inner tank body and extending front and back, the snap-in hole is provided on the horizontal plate, and the top of the water tank is provided with a horizontal buckle that is snapped into the snap-in hole.

[0065] like Figure 8 and Figure 9 As shown, compared with the first embodiment, this embodiment differs in that the fastener 400 is a screw integrally formed with the fixed shaft 210, and the mounting portion 310 is provided with a second threaded hole 316. Specifically, the second through hole in the first embodiment is designed as a threaded hole, and the screw passes through the first through hole 101 and is threadedly connected to the second threaded hole 316. This design further reduces the number of components in the liner structure, thereby further reducing assembly complexity and making assembly more convenient. It also avoids the problem of assembly failure caused by the loss of fastener 400.

[0066] Example 3

[0067] like Figure 2 As shown, this embodiment provides a dishwasher comprising a base 600, on which the inner container structure described in Embodiments 1 or 2 is mounted, with the projection of the water tank 300 on the base 600 being located within the base 600. This design facilitates installation of the dishwasher within a cabinet for built-in dishwashers, as the water tank will not exceed the dimensions of the base and thus prevent it from being unable to fit within the cabinet. Furthermore, for tabletop dishwashers, it facilitates assembly of the dishwasher housing with the base 600.

[0068] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
