[0052] Referring to Figures 1-10 , an embodiment of the handle mounting structure of the dishwasher door body is aimed at solving the problems of the handle mounting structure of the traditional dishwasher door body, such as difficult disassembly and installation, etc.

[0053] The handle mounting structure of the dishwasher door body comprises a control panel support 100 and a lower handle 200.

[0054] The control panel support 100 is an important part of the handle mounting structure of the dishwasher door body, and its main function is to bear and fix the control panel of the dishwasher, and to serve as the core frame of the door body structure, and to be fixedly connected with other door body components (such as the lower handle 200, the door body shell, etc.), to jointly constitute a complete door body structure.

[0055] As shown in Figure 3 , the two end side walls of the control panel support 100 extend downward to form a side plate mounting portion 110, which is used for connecting with the lower handle 200. As shown in Figure 2 , the bottom surface of the control panel support 100 is provided with a hand buckle groove 140 which is concave upward.

[0056] The lower handle 200 is installed between the two side plate mounting portions 110. The lower handle 200 has a concave space a which is concave backward, and the concave space a cooperates with the hand buckle groove 140 on the control panel support 100 to form a complete handle space, thereby providing a holding area for the user.

[0057] In order to ensure the stability and positioning accuracy of the installation of the lower handle 200, and to play a guiding role in the installation process, as shown in Figure 5As shown, the lower handle 200 extends outwardly at its two ends along the front edge to form a stop portion 210, which is used to abut against the front end of the side plate mounting portion 110 to limit the rearward movement of the lower handle 200.

[0058] The outer side wall of each end of the lower handle 200 is provided with a limiting portion 220, and the inner side of the side plate mounting portion 110 is correspondingly provided with a limiting matching portion 120. Figure 8 As shown, the limiting matching portion 120 abuts against the rear side of the limiting portion 220 to limit the forward movement of the lower handle 200.

[0059] During installation, the lower handle 200 is slid forwardly and rearwardly between the two side plate mounting portions 110, and after the stop portion 210 abuts against the front end of the side plate mounting portion 110, the lower handle 200 is pushed upwardly, and the limiting portion 220 on the lower handle 200 can be slid along the limiting matching portion 120 to be in place, and the limiting matching portion 120 abuts against the rear side of the limiting portion 220 to limit the forward movement of the lower handle 200. Thus, the forward and rearward displacement of the lower handle 200 is limited.

[0060] In order to firmly fix the lower handle 200 on the control panel support 100, the rear side of the lower handle 200 is provided with at least one handle fixing portion 250. Figure 9 As shown, the control panel support 100 extends downwardly along its rear side to form a support mounting portion 160. After the limiting portion 220 is slid to be in place, the handle fixing portion 250 abuts against the support mounting portion 160 and is fixedly connected through fasteners (such as screws). This connection mode not only ensures the firmness of the connection, but also facilitates disassembly and maintenance.

[0061] The handle mounting structure of the above-mentioned dishwasher door body realizes the preliminary positioning of the lower handle 200 through the abutment of the stop portion 210 and the side plate mounting portion 110, and the sliding cooperation of the limiting portion 220 and the limiting matching portion 120 further simplifies the installation process, without the need for complex alignment and adjustment. Only the lower handle 200 needs to be pushed to be in place and the fasteners are tightened to complete the installation, greatly reducing the installation difficulty. When disassembled, only the fasteners need to be loosened, and the lower handle 200 is easily disassembled by being pushed downwardly and forwardly, greatly improving the maintainability of the product.

[0062] In the present embodiment, the limiting portion 220 includes a first vertical plate portion 221 and an inclined plate portion 222 connected to the top end of the first vertical plate portion 221, and the inclined plate portion 222 is arranged to be inclined rearwardly, and the front side of the first vertical plate portion 221 abuts against the rear side of the limiting matching portion 120. The inclined design of the inclined plate portion 222 can better guide the lower handle 200 to be in place during installation and provide more reliable limiting effect.

[0063] Further, the limiting part 220 further comprises a first horizontal plate part 223, which is connected to the lower end of the first vertical plate part 221 and is arranged away from the limiting and matching part 120. The addition of the first horizontal plate part 223 can enhance the structural strength of the limiting part 220, improve its ability to withstand external force, and further ensure the stability of the installation of the lower handle 200.

[0064] In the present embodiment, the side walls at both ends of the lower handle 200 are arranged to be inclined from front to back, and the outer side of the inclined side walls is provided with a buckle part 230 extending rearward along the baffle part 210, and the buckle part 230 is arranged close to the bottom surface of the lower handle 200. The inner side surface of the side plate mounting part 110 is provided with a buckle matching part 130 protruding therefrom, which forms a slot structure with an open bottom, and the buckle part 230 is inserted into the slot structure to limit the outward bending of the side plate mounting part 110, i.e., to limit the flaring of the side plate mounting part 110, thereby further enhancing the connection stability between the lower handle 200 and the side plate mounting part 110.

[0065] The buckle structure at the lower part of the lower handle 200 is designed to complete the clamping operation at the same time when the lower handle 200 is slid upward into position, cooperate with the limiting part 220, and complete the connection with the side plate mounting part 110, which is convenient and fast and improves the assembly efficiency. At the same time, the cooperation of the buckle part 230 and the slot structure effectively limits the outward bending of the side plate mounting part 110, thereby enhancing the overall rigidity of the door body.

[0066] Specifically, as Figure 5 shown, the buckle part 230 comprises a second horizontal plate part 231, a second vertical plate part 232 connected to the rear end of the second horizontal plate part 231, and a connecting side plate part 233 connected between the second horizontal plate part 231 and the second vertical plate part 232. The connecting side plate part 233 can enhance the strength of the buckle part 230 and prevent it from deforming or breaking during use.

[0067] As Figure 7 shown, the buckle matching part 130 comprises a third vertical plate part 131 connected perpendicularly to the inner side surface of the side plate mounting part 110, a fourth vertical plate part 132 connected to the third vertical plate part 131, and a top plate part 133 connected to the top parts of the third vertical plate part 131 and the fourth vertical plate part 132; the third vertical plate part 131, the fourth vertical plate part 132, the top plate part 133, and the inner side surface of the side plate mounting part 110 together form a slot structure. This slot structure can form a good cooperation with the buckle part 230 to achieve effective limiting and connection.

[0068] Referring to Figure 10In the embodiment, the rear top of the lower handle 200 is provided with at least one upward protruding positioning part 240, and the control panel support 100 is provided with a positioning groove 150 corresponding to the positioning part 240, and the positioning part 240 is inserted into the positioning groove 150. Specifically, the positioning part 240 is usually designed as a protruding column, a protruding block or a protruding strip, and the positioning groove 150 is a groove or a hole matched with the shape of the positioning part 240. When the lower handle 200 is installed, the positioning part 240 is accurately inserted into the positioning groove 150, which can firstly ensure the accurate position of the lower handle 200 in the horizontal and vertical directions, avoid installation deviation, and improve the assembly efficiency and product consistency. Secondly, the cooperation of the positioning part 240 and the positioning groove 150 can effectively disperse the external force received by the lower handle 200, especially the force received by the upper part, to prevent the lower handle 200 from being deformed, such as bending and twisting, due to long-term use or external force. This design is especially suitable for the case that the length of the lower handle 200 is relatively long or the material strength is relatively low, which can significantly improve the structural strength and service life of the lower handle 200.

[0069] The handle fixing part 250 includes a plurality of rearward protruding cylindrical screw columns arranged along the length direction of the lower handle 200, and the rearward protruding screw columns are provided with threaded holes in the axial direction, which are used for screw connection with the support mounting part 160.

[0070] The support mounting part 160 is formed as a plate-shaped structure extending downward along the rear side of the control panel support 100, and is provided with through holes corresponding to the threaded holes of the screw columns, and the screws are screwed through the through holes and the threaded holes of the screw columns.

[0071] In the embodiment, the rear side of the lower handle 200 is provided with a plurality of reinforcing ribs 260. The reinforcing ribs 260 can enhance the structural strength of the lower handle 200 and prevent it from being deformed or broken during use.
