Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] This embodiment discloses a dishwasher bottom shell structure, which serves as the bottom structure of the dishwasher's cabinet, referring to... Figures 1-6The dishwasher includes a base 1 and a bottom cover 4. The base 1 is located at the bottom of the dishwasher, and a bottom opening 2 is provided on the underside of the base 1. The bottom cover 4 is located at the bottom opening 2 and can close the bottom opening 2, thus enclosing all the components at the bottom of the dishwasher.
[0030] A recess 401 is formed in the center of the bottom cover 4, which can accumulate a certain amount of overflow water from the dishwasher. An overflow protection switch is installed at the lowest point of the recess 401 to detect the amount of overflow water. In addition, an overflow outlet 402 is provided at a position on the bottom cover 4 slightly higher than the recess 401. When the overflow water in the bottom cover 4 reaches a certain level, it can be discharged from the overflow outlet 402 to prevent short circuits in the internal circuit components of the dishwasher, thus avoiding damage to the electrical appliances and the risk of electric shock.
[0031] Reference Figure 1 , Figure 2 , Figure 3 As shown, several fixing clips 6 and elastic clips 7 are provided on the outer extension 5 of the bottom cover 4. The fixing clips 6 can be fixedly engaged with the bottom cover 4, while the elastic clips 7 can provide elastic engagement, forming an auxiliary positioning to facilitate installation and disassembly. In addition, there is a screw fixing position between the bottom cover 4 and the base 1, which is used to lock the two together.
[0032] Reference Figure 4 , Figure 5 As shown, the fixing buckle 6 and the bottom cover 4 are integrally formed, including a protrusion 61 and a snap-fit part 62. The protrusion 61 is integrally connected to the upper side of the outer extension 5 of the bottom cover 4, and the snap-fit part 62 is fixedly connected to the upper end of the protrusion 61 and extends towards the outer periphery of the bottom cover 4. A snap-fit gap 63 is formed between the snap-fit part 62 and the outer extension 5 of the bottom cover 4, and the height of the snap-fit gap 63 is adapted to the height of the inner edge 3 of the bottom opening 2. During installation, the inner edge 3 of the bottom opening 2 can be partially embedded into the snap-fit gap 63 of the fixing buckle 6. After snapping, it can form a vertical limit, and the protrusion 61 abuts against the inner edge 3 of the bottom opening 2 to achieve a horizontal limit.
[0033] To improve the snap-fit stability of the fixing buckle 6, several limiting protrusions 311 are formed on the inner edge 3 of the bottom opening 2, and the limiting protrusions 311 correspond one-to-one with the fixing buckle 6. During snap-fit, the limiting protrusions 311 can be engaged into the snap-fit gap 63, which can extend the contact position of the fixing buckle 6 during snap-fit, thereby improving the snap-fit stability and strength.
[0034] Reference Figure 6As shown, the elastic buckle 7 and the bottom cover 4 are integrally formed, including an elastic part 71 and a second snap-fit part 72. The elastic part 71 is integrally connected to the outer extension 5 of the bottom cover 4, and the second snap-fit part 72 is fixedly connected to the side of the elastic part 71 facing the outer periphery of the bottom cover 4. The elastic part 71 can elastically deform towards the inner periphery of the bottom cover 4, and the second snap-fit part 72 can elastically deform towards the inner periphery of the bottom cover 4 in accordance with the elastic part 71. During installation, the second snap-fit part 72 can make way for the elastic deformation of the elastic part 71. After installation, the second snap-fit part 72 is engaged and fitted with the inner edge 3 of the bottom opening 2 to form a fixed shape.
[0035] The elastic part 71 has an inverted U-shaped structure, including a first connecting part 711, an arc-shaped connecting part 712, and a second connecting part 713. The lower end of the first connecting part 711 is fixedly connected to the outer extension 5 of the bottom cover 4. The first connecting part 711 and the second connecting part 713 are generally parallel, with the second connecting part 713 located near the outer periphery of the bottom cover 4. The upper ends of the first connecting part 711 and the second connecting part 713 are connected by the arc-shaped connecting part 712, leaving the second connecting part 713 suspended. The second connecting part 713 can elastically deform relative to the first connecting part 711, achieving elastic deformation through the elasticity of the material itself in each segment of the elastic part 71. The snap-fit part 72 is fixedly connected to the second connecting part 713, located on the outside of the second connecting part 713, and can elastically deform along with the second connecting part 713, thereby achieving snap-fit fixation with the inner edge 3 of the bottom opening 2.
[0036] A clearance notch 73 is provided on the outer extension 5 of the bottom cover 4 corresponding to the position of the elastic part 71. The lower end of the second connecting part 713 extends out of the clearance notch 73 to the outside of the bottom cover 4. When disassembly is required, the lower end of the second connecting part 713 can be directly fastened from the lower part of the bottom cover 4, causing the second locking part 72 to elastically deform in the inward direction, thereby allowing the elastic buckle 7 to be opened for easy disassembly.
[0037] In addition, a positioning groove 321 is provided at the corresponding position of the three pairs of elastic buckles 7 on the inner edge. The second connecting part 713 of the elastic buckle 7 can be embedded in the positioning groove 321, which can limit the buckling position of the elastic buckle 7 to maintain the stability of the assembly position and also play a positioning role.
[0038] Reference Figures 1-3 As shown, the bottom cover 4 has a roughly quadrilateral structure, and its outer extension 5 has four edges. The outer extension 5 includes a bottom shell snap-fit edge 51. The bottom shell snap-fit edge 51 is located on the back of the dishwasher. Three sets of fixing buckles 6 are provided on the bottom shell snap-fit edge 51, and the snap-fit portions 62 of each fixing buckle 6 face the same direction.
[0039] The inner edge 3 of the bottom opening 2 includes an opening snap-fit edge 31, which is opposite to the bottom shell snap-fit edge 51; and the opening snap-fit edge 31 is provided with a plurality of limiting protrusions 311, which are snapped into the snap-fit gap 63.
[0040] The outer extension 5 of the bottom cover 4 includes several bottom shell snap-fit edges 52, with three edges 52 in total. One edge is opposite to the bottom shell snap-fit edge 51, and the other two are adjacent to the bottom shell snap-fit edge 51. Elastic buckles 7 are distributed on each bottom shell snap-fit edge 52, capable of snapping and fixing the three edges of the bottom cover 4 to the inner edge 3 of the bottom opening 2. Correspondingly, the inner edge 3 of the bottom opening 2 includes several opening snap-fit edges 32, with each opening snap-fit edge 321 corresponding to one of the bottom shell snap-fit edges 52. A positioning groove 321 is formed on the opening snap-fit edge 321, and at least a portion of the elastic buckle 7 is inserted into the positioning groove 321 to achieve positioning.
