Description

Technical Field

[0001] The utility model relates to a dishwasher door body, in particular to a dishwasher door body hanging plate structure. Background Art

[0002] The door of a dishwasher is generally a component that combines a plate frame and a glass panel. In order to ensure that the frame has sufficient mechanical properties, it is necessary to fill the sheet metal frame with supporting components. Existing supporting components include wooden supports, which easily absorb water vapor, causing expansion and rot. In addition, because the outer wall of the sheet metal frame is thin and the internal groove is narrow, it is difficult to insert the supporting component into the groove, especially for the square frame-shaped supporting component, which is more difficult to assemble with the sheet metal frame. Moreover, whether the supporting component is made of wood or plastic, it is difficult to fix it with screws, which leads to a decrease in the overall performance and service life of the dishwasher door.

[0018] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0019] The utility model discloses a dishwasher door hanging plate structure, combined with Figures 1 to 4As shown, it includes a sheet metal door frame 1 and a support bar assembly 2 which is arranged on the inner side of the sheet metal door frame 1 and is in the shape of a square frame. The support bar assembly 2 includes two horizontal struts 20 which are arranged vertically and parallel to each other and two vertical struts 21 which are arranged left and right and parallel to each other. A trapezoidal strut 22 is provided between adjacent horizontal struts 20 and vertical struts 21, and the horizontal struts 20, the trapezoidal struts 22 and the vertical struts 21 are spliced ​​and connected in sequence. A slot 210 is provided on the vertical strut 21, and the slot 210 extends to the end of the vertical strut 21. A nut plate 23 is inserted in the slot 210 and the two are engaged with each other. The sheet metal door frame 1 and the nut plate 23 are fixedly connected by screws.

[0020] In the above structure, the sheet metal door frame 1 is in the shape of a square frame as a whole, and has a groove 11 on the inner side for accommodating the support bar assembly 2. Two horizontal struts 20 arranged vertically and parallel to each other are respectively embedded in the grooves 11 on the upper and lower sides, and four trapezoidal struts 22 are respectively spliced ​​at the two ends of the horizontal struts 20. Two vertical struts 21 arranged left and right and parallel to each other are correspondingly inserted in the grooves 11 between the two trapezoidal struts 22, thereby forming the basic structure of the support bar assembly 2. On this basis, the utility model provides a slot 210 on the vertical strut 21, and the nut plate 23 is inserted into the slot 210 by the end of the vertical strut 21, and then the sheet metal door frame 1 and the nut plate 23 are fixed by screws. Compared with the prior art, the utility model is more convenient to assemble based on the above structure, and it is easy to fix the sheet metal door frame 1 and the nut plate 23. In addition, the utility model can enhance the connection reliability between the sheet metal door frame 1 and the support bar assembly 2 by embedding the nut plate 23 on the vertical support bar 21, and can effectively avoid the occurrence of screw slippage, thereby improving the overall performance and service life of the dishwasher door.

[0021] In order to securely fasten the nut plate 23, in this embodiment, see Figure 3 Buckle grooves 211 are formed on both sides of the slot 210 , and L-shaped folded edges 230 are formed on both side edges of the nut plate 23 . The two L-shaped folded edges 230 are respectively inserted into the two buckle grooves 211 .

[0022] In this embodiment, in order to reduce the overall weight of the support bar assembly 2, each component needs to be made into a hollow shape. Figure 3 The transverse struts 20 , the trapezoidal struts 22 and the vertical struts 21 all include a hollow inner cavity 200 .

[0023] As a preferred embodiment, the surfaces of the transverse brace 20, the trapezoidal brace 22 and the vertical brace 21 are all formed with ribs 201, and the ribs 201 are in close contact with the sheet metal door frame 1. The purpose of setting the ribs 201 in this embodiment is that when the assembler installs the transverse brace 20, the trapezoidal brace 22 and the vertical brace 21 into the sheet metal door frame 1, black glue can be applied to the surface with the ribs 201 first, and the sheet metal door frame 1 and the support bar assembly 2 can be reliably fixed by using the black glue between the ribs 201 and the sheet metal door frame 1.

[0024] In this embodiment, the two stays at the corners are fixed by angle brackets. Figure 3 The connection between the transverse brace 20 and the trapezoidal brace 22 is provided with an L-shaped corner bracket 24, and the two ends of the L-shaped corner bracket 24 are respectively inserted into the hollow inner cavity 200 of the transverse brace 20 and the hollow inner cavity 200 of the trapezoidal brace 22. In order to enhance the stability of the support bar assembly 2, the transverse brace 20 and the trapezoidal brace 22 can be fixedly connected to the L-shaped corner bracket 24 by screws, rivets, etc.

[0025] As a preferred embodiment, the transverse support bar 20 and the trapezoidal support bar 22 are both fixedly connected to the L-shaped angle bracket 24 by screws.

[0026] See also Figure 1 In this embodiment, a glass door panel 3 is fixed to the front side of the sheet metal door frame 1 .

[0027] See also Figure 4 The sheet metal door frame 1 in this embodiment is composed of four sheet metal parts. Specifically, the sheet metal door frame 1 includes four sheet metal frames 10 spliced ​​in a square shape.
