DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] This embodiment discloses a dishwasher housing, referring to Figures 1-12 For explanation, the shell is roughly in the shape of a cube, including a bottom shell 10, a top shell 60, a rear cover 40, a bottom cover 30 and two side covers 50. An opening is formed on the front side of the shell, and the door of the dishwasher is installed at the opening.

[0035] The top shell 60 is located above the bottom shell 10, while the rear cover 40 and two side covers 50 are located between the bottom shell 10 and the top shell 60. The upper and lower sides of the rear cover 40 are respectively engaged with the bottom shell 10 and the top shell 60. The upper and lower sides of the side covers 50 are respectively engaged with the bottom shell 10 and the top shell 60. The sides of the rear cover 40 are respectively engaged with the two side covers 50. The rear cover 40 and the two side covers 50 serve as the three side panels of the dishwasher housing and are open toward the front.

[0036] The bottom of the bottom shell 10 is open and has a bottom opening 11. The bottom opening 11 is closed by a bottom cover 30. The bottom cover 30 is snap-fitted to the bottom shell 10 and then fixed with a first screw 100 to complete the installation of the bottom cover 30.

[0037] The bottom opening 11 can form an opening at the bottom of the dishwasher for easy disassembly, so as to facilitate the installation of components at the bottom of the dishwasher inner tank and also facilitate the subsequent inspection and maintenance of the components at the bottom of the dishwasher inner tank.

[0038] Reference Figure 1 、 Figure 7 、 Figures 9-11 As shown, the connections between the rear cover plate 40, the two side cover plates 50 and the top shell 60 are snapped together by a first snap structure 70. The two side edges of the rear cover plate 40 are snapped together with the two side cover plates 50, and the lower side edge of the top shell 60 is snapped together with the upper side edges of the rear cover plate 40 and the two side cover plates 50.

[0039] Reference Figure 3 As shown, the first snap-fit ​​structure 70 includes a first snap-fitting slot 71 and a first snap-fitting block 72 that fit together. The first snap-fitting slot 71 and the first snap-fitting block 72 are respectively located at two connecting portions 400 of the first snap-fit ​​structure 70. The two connecting portions 400 are the two components that need to be snap-fitted together, such as the snap-fitting connection between the rear cover 40 and the side cover 50. The two connecting portions 400 are located at the two edges of the rear cover 40 and the side cover 50.

[0040] When the first snap structure 70 is assembled, the first latch block 72 partially penetrates the first latch slot 71. The first latch block 72 has a hook-like structure that can be hooked into the first latch slot 71 to achieve a secure connection. A first latch slot portion 711 is defined within the inner periphery of the first latch slot 71, and a second latch slot portion 721 is defined within the first latch block 72. The first latch slot portion 711 and the second latch slot portion 721 can engage with each other to achieve a secure connection.

[0041] The width of the first slot 711 is smaller than that of the first slot 71. An inclined guide portion 712 is provided between the first slot 711 and the first slot 71. The width of the guide portion 712 gradually decreases toward the first slot 711, providing guidance and positioning during engagement. Furthermore, an inclined guide portion 722 is formed at the opening of the second slot 721. The guide portion 722 is formed in the shape of an inclined slope and gradually decreases toward the interior of the second slot 721, providing guidance during engagement.

[0042] Reference Figure 8 As shown, a threaded connection part 1 201 is fixedly connected to the side cover plate 50, and a threaded connection part 4 202 is fixedly connected to both sides of the rear cover plate 40. The threaded connection part 1 201 and the threaded connection part 202 are stacked on each other and fixedly connected by a second screw 200.

[0043] Reference Figure 11 As shown, screw connection holes are preset on the upper side of the rear cover plate 40 . After the top shell 60 is snap-fitted and installed, it is threadedly connected and fixed to the rear cover plate 40 by the third screws 300 .

[0044] Reference Figure 4 、 Figure 5 、 Figure 7 As shown, the connection between the bottom cover plate 30 and the bottom shell 10 is snapped together by a second snap-fit ​​structure 80 . The second snap-fit ​​structure 80 is an elastic snap-fit ​​structure, and its elasticity comes from the elasticity of the plastic itself.

[0045] The second snap-fit ​​structure 80 includes an elastic portion 82 connected to the bottom cover 30. The elastic portion 82 has an inverted U-shaped structure, allowing for a certain degree of elastic deformation. A second latch 821 is fixedly attached to the elastic portion 82, facing the outer periphery of the bottom cover 30. The second latch 821 can move with the elastic portion 82, elastically deforming toward the inner periphery of the bottom cover 30 and engaging the inner periphery of the bottom opening of the bottom case 10.

[0046] In order to improve the accuracy of the assembly position of the bottom cover 30, a second card slot 81 is opened on the inner periphery of the bottom opening of the bottom shell 10. The number and position of the second card slots 81 correspond to the elastic parts 82 one by one. By limiting multiple card positions, the position of the entire bottom cover 30 can be limited.

[0047] The second slot 81 is recessed within the inner periphery of the bottom opening 11, and the elastic portion 82 is capable of elastically snapping into the second slot 81. The profile of the second clamping block 821 protrudes relative to the second slot 81. Pressing the elastic portion 82 elastically deforms the second clamping block 821, allowing it to fall within the second slot 81 and pass through the slot normally. Once the second clamping block 821 is inserted into the second slot 81, releasing the elastic portion 82 causes it to elastically return to its original position, allowing the second clamping block 821 to form a stable snap-fit ​​structure with the second slot 81.

[0048] After the bottom cover 30 is assembled, the bottom cover 30 and the bottom shell 10 are fixedly connected by the first screws 100 to prevent the bottom cover 30 from falling off.

[0049] Reference Figure 6 、 Figure 7 As shown, the bottom case 10 is connected to the rear cover 40 and the two side covers 50 via a third snap-fit ​​structure 90. The third snap-fit ​​structure 90 includes a third slot 91 and a third block 92. The third slot 91 is defined on the upper side of the bottom case 10, corresponding to the installation position of the rear cover 40 and the two side covers 50. The third block 92 is fixedly connected to the lower side of the rear cover 40 and the two side covers 50. The third block 92 corresponds to the position of the third slot 91, and the mutual adaptation enables snap-fit ​​connection.

[0050] During installation, the third clamping block 92 is inserted from top to bottom into the third clamping slot 91 to achieve a fixed position. To improve the installation stability of the rear cover 40 and the two side cover plates 50, after the third clamping structure is engaged, they can be fixed to the outer side of the inner liner with bolts, thereby improving the installation stability of each cover plate.

[0051] Reference Figure 1 、 Figure 7 、 Figure 9As shown, a skirting board 20 is mounted on the lower front side of the housing. The skirting board 20 cooperates with the dishwasher door to maintain a roughly even height on the front side of the dishwasher. Specifically, the skirting board 20 is fixedly connected to the front side of the bottom housing 10. The skirting board 20 and the bottom housing 10 are engaged and secured together by bolts.

[0052] In addition, a through-hole is provided in the center of the front side of the top shell 60, into which a door opening button 61 of a suitable shape is mounted. Door opening button 61 is movable up and down, interlocking with the door opening mechanism inside the dishwasher. A portion of door opening button 61 extends into the underside of the top shell 60 and engages with it, allowing it to swing up and down relative to the top shell 60.

[0053] Reference Figure 12 As shown, a connecting block 612 is fixedly connected to the lower side of the top shell 60 near the through hole. The connecting block 612 has a rotating connecting slot 613, and the rotating connecting slot 613 has a notch 614. The width of the notch 614 is slightly smaller than the rotating connecting slot 613. The door opening button 61 is integrally formed with a rotating shaft 611. The rotating shaft 611 is sized to match the rotating connecting slot 613. The rotating shaft 611 can pass through the notch 614 and snap into the rotating connecting slot 613. The rotating shaft 611 can be rotated and adjusted in the rotating connecting slot 613, thereby allowing the entire door opening button 61 to move up and down at the through hole of the top shell 60.
