[0048] Embodiment 1

[0049] As Figures 1 to 5 shown, in this embodiment, the dishwasher includes an inner tank 100 and a soft water purifier. The soft water purifier includes a soft water purifier body 200 and a soft water purifier cover 300. Among them, the soft water purifier body 200 penetrates through the bottom wall of the inner tank 100. The soft water purifier body 200 is provided with a soft water purifier opening 210 located inside the inner tank 100. The soft water purifier cover 300 is detachably connected to the soft water purifier body 200 by clamping or screwing to close the soft water purifier opening 210. In this embodiment, it is preferably that the soft water purifier cover 300 is detachably connected to the soft water purifier body 200 by screwing, such as threaded connection or screw buckle connection. Preferably, a plurality of circumferentially spaced screw buckle grooves 301 are provided on the inner side of the top wall of the soft water purifier cover 300, and a screw buckle 211 is provided on the outer peripheral side of the soft water purifier body 200. By rotating the soft water purifier cover 300, the screw buckle can be screwed into the screw buckle groove to realize the screwing connection between the soft water purifier cover 300 and the soft water purifier body 200. With such a design, the disassembly and assembly of the soft water purifier cover 300 and the soft water purifier body 200 can be completed by manually rotating the soft water purifier cover 300, thereby reducing the disassembly and assembly difficulty of the soft water purifier cover 300 and the soft water purifier body 200, and further improving the maintenance efficiency of after-sales personnel.

[0050] In addition, the dishwasher in this embodiment further includes an interface component, which includes a connection port and a connecting piece. The connecting piece is disposed inside the inner container 100 and is screwed to the connection port to fix the connection port on the inner container 100. The screwing connection can adopt snap connection or threaded connection. The water softener cover 300 is provided with a mating portion 310, and the mating portion 310 can be circumferentially positioned and mated with the connecting piece. Since the connecting piece and the connection port are screwed together, through the circumferential positioning and mating of the mating portion 310 and the connecting piece, the synchronous rotation of the water softener cover 300 and the connecting piece can be achieved. In this way, the disassembly and assembly of the connecting piece can be realized by rotating the water softener cover 300 to drive the connecting piece to rotate synchronously, that is, using the water softener cover 300 as a disassembly and assembly jig to realize the disassembly and assembly of the connecting piece. Thus, the special disassembly and assembly jig for disassembling and assembling the connecting piece can be omitted, achieving the effect of reducing the number of disassembly and assembly jigs and the manufacturing cost. At the same time, the number of disassembly and assembly jigs carried by after-sales personnel can also be reduced, improving the work convenience of after-sales personnel.

[0051] Specifically, the dishwasher in this embodiment further includes a breather, which includes a breather port (not shown in the figure) and a breather cover 400. The breather port forms the above-mentioned connection port, and the breather cover 400 forms the connecting piece. The top wall of the breather cover 400 is provided with a plurality of first through holes 410 arranged around its center. The first through holes 410 communicate the breather port and the inside of the inner container 100. The mating portion 310 includes a plurality of convex columns 311 arranged on the inner side of the top wall of the water softener cover. The number of the convex columns 311 is not more than the number of the first through holes 410, and the convex columns 311 are inserted and mated with the first through holes 410. With such a design, the circumferential positioning and mating of the water softener cover 300 and the breather cover 400 can be realized through the cooperation of the convex columns 311 and the first through holes 410, that is, the water softener cover 300 and the breather cover 400 will not rotate relative to each other. With such a design, the water softener cover 300 can be used as a disassembly and assembly jig to disassemble and assemble the breather cover 400, and there is no need to prepare a special disassembly and assembly jig for disassembling and assembling the breather cover 400. In addition, with such a design, not only can the circumferential positioning and mating effect between the mating portion 310 and the breather cover 400 be enhanced, but also when the water softener cover 300 is connected to the water softener body 200, the convex columns 311 can be hidden inside the water softener body 200 to prevent the convex columns 311 from being exposed and affecting the appearance. In addition, the side wall of the breather cover 400 can be a circular side wall to improve the appearance of the breather cover 400.

[0052] It can be understood that in other embodiments of the present invention, a non-circular hole, such as a hexagonal hole, a D-shaped hole, a quadrilateral hole, etc., is provided at the central portion of the breather cover, and the corresponding mating portion is a convex column provided at the central portion of the inner side of the top wall of the water softener cover. The cross-sectional shape of the convex column is matched with the non-circular hole. With such a design, the circumferential positioning and mating between the mating portion and the breather cover can also be realized.

[0053] It can be understood that in other embodiments of the present utility model, in order to enhance the circumferential positioning and mating effect between the mating part and the breather cover, the top wall of the breather cover is provided with a plurality of first through holes arranged around its center and a non-circular hole provided at its central portion. The mating part includes a convex post provided on the inner side of the top wall of the water softener cover. One of the convex posts is inserted into the non-circular hole, and the remaining plurality of convex posts are respectively inserted into the remaining plurality of first through holes one by one.

[0054] When disassembling and assembling the breather cover 400, the after-sales personnel can drive the water softener cover 300 to rotate by manually screwing the water softener cover 300. Since the outer peripheral surface of the side wall of the water softener cover 300 is a cylindrical surface, it is relatively laborious. In order to make it more labor-saving to rotate the water softener cover 300 to drive the breather cover 400 to rotate, in this embodiment, a first operation part 320 for cooperating with a wrench is further provided at the central portion of the outer side of the top wall of the water softener cover 300. The first operation part 320 includes a first hexagon socket 321 and a first polygonal prism 322. The first polygonal prism 322 protrudes from the outer side of the top wall of the water softener cover 300 and extends along the axial direction of the water softener cover 300. The first polygonal prism 322 can be a quadrangular prism, a hexagonal prism, etc. The first hexagon socket 321 is provided on the first polygonal prism 322 and is coaxially arranged with the first polygonal prism 322. With such a design, the after-sales personnel can use a fixed-end wrench or an adjustable wrench to screw the first polygonal prism 322 or use an internal hexagon wrench to insert into the first hexagon socket 321 to screw and realize driving the water softener cover 300 to rotate synchronously, so as to realize the disassembly and assembly of the breather cover 400, and further make the disassembly and assembly of the after-sales personnel more labor-saving, thereby improving the maintenance efficiency of the after-sales personnel.

[0055] It can be understood that in other embodiments of the present utility model, in order to simplify the structure of the first operation part, the first operation part only includes a first hexagon socket, and the first hexagon socket is a blind hole provided on the outer side of the top wall of the water softener cover; or, the first operation part only includes a first polygonal prism protruding from the outer side of the top wall of the water softener cover. With such a design, it is also possible to drive the water softener cover to rotate synchronously by screwing the first operation part with a wrench.

[0056] In addition, in this embodiment, a circular rib 330 is further provided on the inner side of the top wall of the water softener cover 300. The circular rib 330 surrounds the outside of the plurality of convex posts 311 to enclose the plurality of convex posts 311. An annular groove is provided on the outer peripheral side of the circular rib 330 and a sealing ring 331 is embedded in the annular groove. After the water softener cover 300 is connected to the water softener body 200, the circular rib 330 is inserted into the water softener body 200 through the water softener port 210, and the sealing ring 331 is made to abut against the inner wall of the water softener body to realize the sealed connection between the circular rib 330 and the inner wall of the water softener body. With such a design, it can prevent the water in the inner tank 100 from flowing into the water softener body 200 to dilute or contaminate the water softening salt solution.

[0057] Secondly, the dishwasher of this embodiment further includes an air duct and a plug 500. The air duct includes an air duct opening which forms a connection port, and the plug 500 forms the connecting member. The plug 500 includes a threaded section 510 and a multi-prismatic section 520. The threaded section 510 is threadedly connected to the air duct opening. The mating portion 310 includes a sleeve 312 provided on the outer side of the top wall of the water softener cover. The sleeve 312 is eccentrically arranged to avoid the first operating portion 320. The cross-sectional shape of the sleeve 312 is the same as the cross-sectional shape of the multi-prismatic section, so that after the sleeve 312 is sleeved on the outer side of the multi-prismatic section 520, circumferential positioning cooperation can be achieved with the multi-prismatic section 520. With such a design, the water softener cover can also be used as a disassembly and assembly jig to disassemble and assemble the plug 500, eliminating the need to prepare a special disassembly and assembly jig for the plug 500; and the sleeve 312 provided on the outer side of the top wall of the water softener cover will not interfere with the convex column 311 provided on the inner side of the top wall of the water softener cover, resulting in a more reasonable layout.

[0058] In this embodiment, at least one prism surface of the multi-prismatic section 520 is provided with a limiting convex point 521 radially protruding outward, and the wall portion of the sleeve 312 is provided with an avoidance notch 3121 for avoiding the limiting convex point 521. With such a design, circumferential positioning cooperation between the sleeve 312 and the multi-prismatic section 520 can be achieved through the cooperation of the limiting convex point 521 and the avoidance notch 3121, preventing the inner mating surface of the sleeve 312 from deforming and slipping during screwing, so as to further improve the circumferential positioning cooperation effect between the sleeve 312 and the multi-prismatic section 520.

[0059] Preferably, the inner wall of the sleeve 312 is provided with a plurality of limiting ribs 3122 extending along the axial direction of the sleeve 312, and the limiting ribs 3122 abut against the outer side surface of the multi-prismatic section 520. With such a design, axial movement of the plug 500 in the sleeve 312 can be prevented, improving the stability during installation or disassembly.

[0060] Finally, in order to make it easier to rotate the water softener cover 300 to drive the plug 500 to rotate, a second operating portion 340 for cooperating with a wrench is further provided at the center of the inner side of the top wall of the water softener cover in this embodiment. The second operating portion 340 includes a second inner hexagonal hole. Inserting an inner hexagonal wrench into the second inner hexagonal hole and screwing can drive the water softener cover 300 to rotate synchronously, thereby realizing the disassembly and assembly of the plug 500. With such a design, it is easier for after-sales personnel to disassemble and assemble, thus improving the maintenance efficiency of after-sales personnel.

[0061] It can be understood that in other embodiments of the present invention, the second operating portion includes a second polygonal prism provided at the center of the inner side of the top wall of the water softener cover, and an avoidance hole for the second polygonal prism to pass through is provided at the center of the top wall of the respirator cover. The height of the second polygonal prism is greater than the height of the convex column. With such a design, after-sales personnel can drive the water softener cover to rotate synchronously by screwing the second polygonal prism with a fixed-end wrench or an adjustable wrench, thereby realizing the disassembly and assembly of the plug.

[0062] It can be understood that in other embodiments of the present utility model, the second operation part includes a second polygonal prism provided at the center of the inner side of the top wall of the water softener cover and a second hexagonal socket provided on the second polygonal prism. With such a design, after-sales personnel can use a fixed-end wrench or an adjustable wrench to screw the second polygonal prism or insert an inner hexagonal wrench into the second hexagonal socket to screw, which can make it more labor-saving for after-sales personnel to disassemble and assemble, thereby improving the maintenance efficiency of after-sales personnel.

[0063] Embodiment 2

[0064] As Figure 6 and Figure 7 shown, compared with Embodiment 1, the difference in this embodiment is that the multi-prism segment 520 does not have a radially outwardly protruding limiting bump, and the corresponding sleeve 312 does not have an avoidance notch. With such a design, the plug 500 can also be disassembled and assembled by using the water softener cover 300 as a disassembly and assembly jig.

[0065] Embodiment 3

[0066] As Figure 8 shown, compared with Embodiment 1, the difference in this embodiment is that the side wall of the breather cover 400 is polygonal, and the fitting part 310, in addition to including the convex column 311 provided on the inner side of the top wall of the water softener cover, also includes the side wall 313 of the water softener cover. The side wall 313 of the water softener cover can be sleeved outside the side wall of the breather cover 400, and the shape of the side wall 313 of the water softener cover is the same as the shape of the side wall of the breather cover 400. Compared with Embodiment 1, the circumferential positioning and fitting effect between the fitting part 310 and the breather cover 400 can be enhanced; in addition, it is also convenient for after-sales personnel to drive the rotation of the water softener cover 300 by the way of manually screwing the water softener cover 300 without carrying a wrench.

[0067] It can be understood that in other embodiments of the present utility model, the outer peripheral side of the side wall of the water softener cover is a cylindrical surface, and the inner peripheral side is a polygonal cylindrical surface matching the side wall of the breather cover. With such a design, the circumferential positioning and fitting can also be realized through the cooperation between the side wall of the water softener cover and the side wall of the breather cover.

[0068] Embodiment 4

[0069] As Figure 9 and Figure 11 shown, compared with Embodiment 3, the difference in this embodiment is that the multi-prism segment 520 does not have a radially outwardly protruding limiting bump, and the corresponding sleeve 312 does not have an avoidance notch. With such a design, the plug 500 can also be disassembled and assembled by using the water softener cover 300 as a disassembly and assembly jig.

[0070] Embodiment 5

[0071] As Figure 12 andFigure 13 As shown, compared with the first embodiment, the difference in this embodiment is that the water softener cover 300 can only be used for disassembling and assembling the breather cover 400, that is, no sleeve is provided on the outer side of the top wall of the water softener cover 300. At this time, a plurality of first through holes 410 are provided on the top wall of the breather cover 400 and are arranged around its center. The first through holes 410 communicate the breather port and the inside of the inner tank 100, and the engaging portion 310 includes a plurality of protruding posts 311 provided on the inner side of the top wall of the water softener cover.
