Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a door assembly and a dishwasher. Background Art

[0002] Dishwashers are generally closed structures, so they are usually equipped with observation windows to facilitate users to observe the situation inside the machine. In the prior art, in order to improve the integrated installation effect of the observation window and the door frame assembly, a double-layer glass window design is adopted to improve the appearance flatness of the dishwasher door. An outer glass window and an inner glass window are fixedly provided on the outer door frame and the inner door frame respectively, and the line of sight can pass through the inner and outer observation windows to observe the washing of dishes inside the dishwasher. However, the installation and fixing of the double-layer glass window is relatively inconvenient. In addition, the dishwasher is often in a high temperature state during washing. Since the door frame assembly is mostly made of plastic material, plastic has a strong thermal expansion and contraction property. Therefore, after long-term operation, the door frame assembly is prone to warping and deformation, thereby reducing the sealing effect between the inner observation window and the inner door frame, and water vapor easily enters the interior of the door body to form fog on the window, which reduces the observation effect of the observation window. Utility Model Content

[0075] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the visual window module 2 also includes a sealing ring 24, which is arranged on a side of the mounting frame 21 close to the second opening 103, and the sealing ring 24 abuts against the end faces of the mounting frame 21 and the second opening 103, respectively, so that the mounting frame 21 is sealed and connected with the end faces of the second opening 103. By installing the sealing ring 24 on the mounting frame 21, the sealing ring 24 abuts against the inner end face of the second opening 103 of the door frame assembly 1 to achieve a sealing effect, effectively preventing washing water or water vapor from entering the door body through the connection between the mounting frame 21 and the door frame assembly 1 when the dishwasher is working.

[0076] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, in addition to the features of the above embodiment, this embodiment further defines that: a third annular groove 207 is formed on one side of the installation frame 21 away from the outer window 22, and the sealing ring 24 is partially embedded in the third annular groove 207. The third annular groove 207 is provided to facilitate the positioning of the sealing ring 24, which is conducive to improving the installation efficiency and ensuring that the sealing ring 24 can effectively play a sealing role.

[0077] A second aspect of the present application provides a dishwasher.

[0078] This embodiment discloses a dishwasher, including the above-mentioned door assembly. The dishwasher provided in the second aspect of the present application, by adopting any of the above-mentioned door assemblies, uses the mounting frame 21 to fix the window, which can greatly reduce the difficulty of installing the window, which is conducive to achieving the integrated installation effect of the window and the door frame assembly 1. In addition, it can also avoid the problem that after the dishwasher is used for a long time, the door frame assembly 1 is warped and deformed due to thermal expansion and contraction, resulting in the door frame assembly 1 and the window being not tightly connected, and water vapor entering to form fog on the window, which reduces the observation effect of the observation window.

[0079] 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.

[0080] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
