[0002] In recent years, with the improvement of people's quality of life and the pursuit of convenient home life, the dishwasher market has shown a good trend of continuous expansion, with the market size constantly expanding and the product types becoming increasingly diverse.

[0003] The control panel of a modern dishwasher integrates display panel operation functions and is an important interface for users to interact with the dishwasher. However, water vapor is easily generated during the operation of the dishwasher. The display panel may be short-circuited due to the intrusion of water vapor, resulting in abnormal display or even complete failure. In addition, there may be small creatures such as crawling insects in the kitchen, which may also crawl into the display panel, causing damage to the circuit and affecting the normal use of the dishwasher. Utility Model Content

[0004] In view of this, the present invention provides a handle assembly, a door structure, and a dishwasher to solve the problem of water vapor or crawling insects invading the display panel, causing circuit damage or display abnormalities.

[0005] In a first aspect, the present invention provides a handle assembly, including a control panel, a handle, and a display panel; the control panel is provided with a display mounting position; the handle includes a handle portion and a protective cover disposed on one side of the handle portion, the protective cover covering and being installed on the display mounting position, and a receiving space is formed between the protective cover and the control panel; the display panel is disposed within the receiving space.

[0006] Beneficial effects: By incorporating a protective cover as part of the handle and covering the display mounting position, it forms a wraparound enclosure with the control panel. This completely places the display panel within the enclosure, providing direct physical isolation and protection. It effectively resists potential damage from external impacts, scratches, dust, liquid splashes, or accidental contact. It also prevents water vapor from entering or insects from entering the area where the display panel is located, reducing the risk of damage or short circuit failure. This ensures the display panel can operate stably for a long time, effectively extending its service life and guaranteeing the normal use of the dishwasher.

[0007] In one optional embodiment, the handle is located on the side of the control panel where the display mounting position is provided and is connected to the protective cover, and the side of the handle facing away from the protective cover is provided with a handle groove; the control panel is provided with a communication port; when the protective cover is installed in the display mounting position, the communication port and the handle groove communicate to form a handle position.

[0008] Beneficial effects: Because the handle is located on the side of the control panel where the display mounting position is located, the assembly structure of the handle and control panel forms a concealed handle position. This reduces the number of components, avoids occupying external space, and prevents potential bumps and knocks from exposed handles, maintaining a clean appearance for the handle assembly. When the user needs to grip, their fingers naturally embed into the handle position defined by the handle and the connecting port, precisely guiding the user's force application and preventing accidental contact or pressing of the display panel area covered by the protective cover, thus preventing damage to the display panel. The gripping force is transmitted through the handle to the entire protective cover and then distributed to the control panel, avoiding localized stress concentration and reducing the risk of dislocation or deformation of the display panel due to accidental pulling. Furthermore, the handle position is formed when the protective cover is covered, eliminating the need to lift or move the protective cover during gripping, ensuring the display panel remains in a sealed and protected state, guaranteeing long-term stable operation of the display panel.

[0009] In one optional embodiment, the protective cover is provided with a slot, and the control panel is provided with a buckle, the buckle engaging with the slot.

[0010] Beneficial effects: By setting slots on the protective cover and configuring buckles at corresponding positions on the control panel, the pre-positioning and convenient locking of the protective cover and control panel are achieved through the interlocking action between the slots and buckles. This makes the installation process more precise and smooth, enhances the reliability of the connection between the protective cover and the control panel, and effectively resists loosening or detachment caused by accidental collisions, vibrations, etc. during use, ensuring continuous and stable protection of the internal display panel. Furthermore, the snap-fit ​​method is simple to operate, and the installation and removal of the protective cover can be easily and quickly completed without the need for additional tools, improving maintenance and repair efficiency and reducing maintenance costs.

[0011] In one alternative embodiment, the protective cover is detachably secured to the control panel by a first fastener.

[0012] Beneficial effects: The first fastener detachably secures the protective cover to the control panel, providing strong mechanical restraint and effectively resisting the risk of displacement caused by continuous vibration, external impact, or frequent operation. This ensures that the protective cover always tightly covers the display panel, preventing gaps caused by loosening that could weaken its protective function. Furthermore, the detachable design allows for quick removal of the first fastener, safely opening the storage space while maintaining the overall structural integrity of the protective cover. This facilitates cleaning, inspection, or replacement of the display panel, reducing maintenance complexity. The first fastener works in conjunction with the snap-fit ​​pre-positioning mechanism. During installation, the snap-fit ​​first achieves quick and accurate alignment, followed by reinforcement with the first fastener. This improves assembly efficiency and avoids the risk of detachment due to the failure of a single fastener, providing reliable protection for the display panel.

[0013] In one alternative embodiment, the display panel is detachably secured to the display mounting position by a second fastener.

[0014] Beneficial effects: By setting a second fastener, the display panel is directly fixed to the display mounting position, preventing slight movements of the display panel within the housing space. This avoids problems such as loose ribbon cables, poor contact, or component damage, ensuring long-term stable and reliable display function. Furthermore, the detachable design facilitates the installation and removal of the display panel, simplifying maintenance processes such as cleaning, inspection, or replacement. The second fastener, together with the first fastener and pre-positioning clips of the protective cover, forms a double-layer locking structure. Even if the external protective cover loosens due to accidental impact, the display panel can still maintain its positional stability through the independent second fastener, reducing the risk of damage.

[0015] Secondly, the present invention also provides a door structure, including a door assembly and the aforementioned handle assembly; the aforementioned handle assembly is mounted on the door assembly.

[0016] Beneficial effects: Integrating the handle assembly as a single unit and directly mounting it onto the door assembly eliminates the tedious steps of assembling and debugging multiple individual components, simplifying the installation process, reducing installation time and labor costs, and improving production efficiency. Furthermore, while protecting the display panel, it enables rapid installation of the handle assembly, allowing the door assembly to be put into use more quickly, thus improving overall ease of use and responsiveness.

[0017] In one alternative implementation, the door assembly includes a first door body connected to one end of the control panel having a communication port.

[0018] Beneficial effects: By connecting the first door body in the door assembly to the end of the control panel with the connecting port, the door structure layout is ensured to conform to ergonomics, so that the handle position formed at the connecting port naturally matches the direction of force applied by the user, improving the smoothness of the pulling operation; and the handle operation area, display area and door support area are compactly arranged, with each area closely connected but not interfering with each other, reducing the overall volume of the door structure, maximizing the integration of functions in a limited space, achieving intensive use of space, and improving the overall space utilization and practicality of the door structure.

[0019] In one alternative embodiment, the door assembly further includes a second door body located inside the first door body, and the second door body is connected to both the handle assembly and the first door body.

[0020] Beneficial Effects: The second door body, located inside the first door body and connected to both the handle assembly and the first door body, adds an internal support frame to the door structure. This effectively enhances the overall strength and rigidity of the structure, allowing it to better maintain its shape stability under external impacts and frequent opening and closing operations, reducing the risk of deformation and damage, and extending the door's service life. Furthermore, the second door body effectively blocks water vapor from directly flowing to the handle assembly and the first door body, reducing the risk of corrosion, short circuits, and other malfunctions caused by moisture erosion. Simultaneously, in high-temperature conditions, the second door body also acts as insulation, preventing direct heat transfer to the handle assembly and the surface of the first door body, avoiding burns for users.
