[0028] In one embodiment of the present application, a dishwasher is provided, comprising the door body of any one of the following embodiments, and also comprising an inner tank with a cleaning cavity, wherein the door body covers the inner tank, and when the door body covers the inner tank, the door body and the inner tank together enclose a cleaning cavity.

[0029] The present application also provides a door body, which can be applied to a dishwasher or other electrical appliances. Not limited thereto. The door body includes a main body and a screen assembly 100 as described in any of the following embodiments, wherein the screen assembly 100 is rotatably connected to the main body. In other embodiments, the screen assembly 100 can also be fixedly connected to the main body.

[0030] See also Figure 1 , Figure 1 A schematic diagram of the exploded structure of a screen assembly 100 in an embodiment of the present application is shown. The screen assembly 100 provided in an embodiment of the present application can be applied to a dishwasher and installed on a door of the dishwasher, and can also be applied to other electrical appliances.

[0031] like Figure 1 As shown, the screen assembly 100 includes a mounting frame 110 and a display unit board 120. Figure 2 and Figure 3 As shown, Figure 2 and Figure 3 The schematic diagram of the structure of the installation frame 110 in an embodiment of the present application is shown. The installation frame 110 includes an installation surface 111 for installing the display unit board 120. The installation surface 111 is provided with an installation space 1111 and a Figure 2As shown, the glue overflow groove 1112 and the glue filling groove 1113 surround the installation space 1111 from the inside to the outside or from the outside to the inside, wherein the installation space 1111 is used to install electronic components, and the glue filling groove 1113 is used to fill glue to bond the installation frame 110 and the display unit board 120.

[0032] The installation space 1111, the glue overflow groove 1112 and the glue filling groove 1113 are all arranged at intervals. Figure 2 As shown, the overflow glue groove 1112 and the glue filling groove 1113 are both arranged in a ring shape around the installation space 1111. The sealing of the installation frame 110 and the display unit board 120 can be achieved by simply applying glue in the glue filling groove 1113, which greatly reduces the amount of glue used in the production process, reduces costs and ensures reliability. Figure 2 and Figure 3 In the illustrated embodiment, the overflow glue groove 1112 and the glue filling groove 1113 surround the installation space 1111 from the inside to the outside in sequence, and the overflow glue groove 1112 is radially located between the installation space 1111 and the glue filling groove 1113, so that when the glue in the glue filling groove 1113 overflows, it will flow to the overflow glue groove 1112, and will not flow directly to the installation space 1111, so as to protect the electronic components in the installation space 1111 and avoid the screen assembly 100 display abnormality caused by the overflow of glue during the gluing process. In other embodiments, the overflow glue groove 1112 and the glue filling groove 1113 can also surround the installation space 1111 from the outside to the inside in sequence, in which case the overflow glue groove 1112 can store excess glue to prevent the glue from overflowing, and can also alleviate the risk of glue overflow to a certain extent.

[0033] It should be noted that the display unit board 120 in the present application refers to a substrate assembly taking a glass substrate as an example, which does not include electronic components such as a control board. Figure 3 and Figure 4 As shown, for the convenience of description, the annular structure used to separate the installation space 1111 and the glue overflow groove 1112 is the first support ring 115, the annular structure used to separate the glue overflow groove 1112 and the glue filling groove 1113 is the second support ring 116, and the annular structure located on the periphery of the glue filling groove 1113 to separate the glue filling groove 1113 and the outside is the third support ring 117. The third support ring 117 is used to prevent excess glue in the glue filling groove 1113 from overflowing to the outside of the installation frame 110.

[0034] like Figure 1 and Figure 4 As shown, the display unit board 120 is covered on the installation surface 111 and is supported by the first support ring 115, the second support ring 116 and the third support ring 117, and the display unit board 120 at least covers the glue pouring groove 1113, that is, the module at least partially covers the third support ring 117 located on the periphery of the glue pouring groove 1113, so as to bond the installation frame 110 and the display unit board 120 through the glue in the glue pouring groove 1113.

[0035] like Figures 2 to 4 As shown, in one of the embodiments, a glue groove 1114 is recessed at the bottom of the glue pouring groove 1113, and the glue pouring groove 1114 is in an annular structure surrounding the installation space 1111, so that the glue can fill the glue pouring groove 1113 in an annular shape during the gluing process, thereby avoiding uneven filling of the glue pouring groove 1113 in the circumferential direction.

[0036] like Figure 2 and Figure 3 As shown, in one of the embodiments, a glue overflow hole 1115 is opened at the bottom of the glue filling groove 1113, and the glue overflow hole 1115 is located on the outside of the glue filling groove 1114, and plays a role in exhaust and glue overflow during the gluing process, so that when the glue gradually fills the glue filling groove 1113 during the gluing process, the air in the glue filling groove 1113 is discharged from the glue overflow hole 1115, so that the glue can fully fill the glue filling groove 1113 and fill the space between the bottom of the glue filling groove 1113 and the display unit board 120, thereby preventing water vapor on the periphery of the third support ring 117 (i.e., the outside of the screen assembly 100) from entering the installation space 1111 from the installation surface 111.

[0037] like Figure 2 and Figure 3 As shown, in one embodiment, there are multiple glue overflow holes 1115, and the glue overflow holes 1115 are distributed around the glue groove 1114, and the distances between adjacent glue overflow holes 1115 are equal, so that the glue in the glue overflow groove 1112 can be evenly filled.

[0038] In one embodiment, the glue overflow hole 1115 penetrates the mounting frame 110 in a direction perpendicular to the mounting surface 111 so that when there is excess glue, the excess glue can overflow from the mounting frame 110 from the glue overflow hole 1115, thereby preventing excess glue from overflowing into the mounting space 1111.

[0039] like Figures 2 to 4 As shown, in one embodiment, the mounting frame 110 includes an outer frame 112 and an inner frame 113. Figure 4 As shown, the outer frame 112 is recessed with a mounting groove 1121, the inner frame 113 is located inside the mounting groove 1121, and the gap between the side wall of the mounting groove 1121 and the inner frame 113 forms a glue overflow groove 1112. In other embodiments, the mounting frame 110 may also be an integrated structure.

[0040] like Figure 4As shown, in one embodiment, the end faces of the outer frame 112 and the inner frame 113 facing the display unit board 120 are flush to form the mounting surface 111, so that the display unit board 120 can be horizontally mounted on the mounting surface 111, avoiding the uneven mounting surface 111 causing a gap between the display unit board 120 and the mounting surface 111, thereby affecting the electronic components in the mounting space 1111. At the same time, the end faces of the outer frame 112 and the inner frame 113 are flush, so that when too much glue in the glue filling groove 1113 overflows into the overflow glue groove 1112, the overflow glue groove 1112 needs to be completely filled before entering the mounting space 1111, further ensuring the overflow prevention effect of the overflow glue groove 1112.

[0041] like Figure 2 As shown, in one embodiment, the installation frame 110 is further provided with a connection slot 114, which is provided on the bottom wall and / or side wall of the installation space 1111 and communicates with the installation space 1111. The connection slot 114 is used to energize the electronic components in the installation space 1111 through the wires passing through the connection slot 114. The opening position of the connection slot 114 is not limited. Figure 2 As shown, in this embodiment, the connection groove 114 is provided on the bottom wall and the side wall of the installation space 1111. In other embodiments, the connection groove 114 may also be provided on the bottom wall of the installation space 1111, or the connection groove 114 may also be provided on the side wall of the installation space 1111. Figure 1 and Figure 2 As shown, the screen assembly 100 includes a sealing block 130, which fills the connection groove 114 and is provided with at least one threading hole 131, so that the wire can pass through the threading hole 131. The sealing block 130 fills the connection groove 114 to seal the connection groove 114, thereby sealing the installation space 1111 to prevent water vapor from entering the installation space 1111 and causing short circuits of electronic components in the installation space 1111. The sealing block 130 is a flexible material part, which is embedded to fill the connection groove 114. For example, the sealing block 130 is a rubber part.

[0042] The screen assembly 100 provided in the above scheme is configured with an overflow glue groove 1112 and a glue filling groove 1113 in sequence around the periphery of the installation space 1111 for installing electronic components, so that the sealing of the installation frame 110 and the display unit board 120 can be achieved by only applying glue in the glue filling groove 1113, which greatly reduces the amount of glue used in the production process, reduces costs while ensuring reliability, and once there is too much glue in the glue filling groove 1113 during the gluing process, causing overflow, the glue will first flow into the overflow glue groove 1112 and avoid flowing into the installation space 1111, thereby reducing the risk of glue overflowing into the installation space 1111 and affecting the electronic components, and by arranging the overflow glue hole 1115 on the outside of the glue filling groove 1114, the scheduling of the gluing process and the overflow of excess glue are optimized, thereby solving the problem of complete sealing between the glue filling groove 1113 and the display unit board 120.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
