Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a control panel and a cleaning machine for a cleaning machine. Background Technology

[0002] Most household dishwashers on the market today have an openable door at the front, with a control panel on the door for human-machine interaction, making it convenient for users to control the machine.

[0003] For example, the utility model patent CN219480002U entitled "A Dishwasher and Its Door" (application number: CN202320138608.5) discloses a structure that includes a control panel and a control component. The control panel is located on the upper part of the door and includes a housing with an upper opening. The control component is disposed on the control panel and includes an interface panel and an electronic control panel. The bottom of the interface panel is provided with a receiving groove and a cover plate that covers the receiving groove. The electronic control panel has buttons and / or a display screen and is housed in the receiving groove. The interface panel and the housing have a mutually cooperating connecting mechanism, and the interface panel is fixed to the upper opening of the housing through the connecting mechanism.

[0004] The above solution discloses a control panel structure for a dishwasher, which is compatible with the installation of control components with different layouts. However, due to structural and manufacturing limitations, the top of the control panel usually has some enclosed cavities. Since the display screen needs to be attached to the top of the control panel, when the door is heated during the washing process, the gas in the enclosed cavities expands, which can easily cause the display screen to burst open. This allows external water stains to easily enter the control panel and cause electrical component malfunctions. Utility Model Content

[0005] The first technical problem this invention aims to solve is to provide a control panel for a cleaning machine that improves the adhesion reliability of the display screen and thus prevents external water stains from entering, in light of the current state of the technology.

[0006] The second technical problem to be solved by this utility model is to provide a cleaning machine with the above-mentioned control panel, in view of the current state of the prior art.

[0007] The technical solution adopted by this utility model to solve at least one of the above-mentioned technical problems is as follows:

[0008] A control panel for a cleaning machine includes a panel body. The panel body has a hollow interior forming a cavity for mounting electrical components. The top wall of the panel body has a mounting hole that communicates with the cavity and allows some electrical components to pass through. A recessed cavity with an upward opening is provided near the mounting hole. The top wall of the panel body has a channel that connects the mounting hole and the recessed cavity. When a display screen is attached to the upper surface of the panel body, the channel, the recessed cavity, and the mounting hole remain in communication.

[0009] When the top of the door heats up under the influence of the washing environment, the air in the cavity expands, enters the mounting hole through the channel, and is further released into the large open air environment of the door through the mounting hole. The display screen is no longer subjected to the lifting force of the expanding gas. Without changing the screen structure, the problem of the display screen being easy to lift is solved, the adhesion reliability of the display screen is improved, and the intrusion of external water stains is avoided.

[0010] Preferably, the panel body is provided with a baffle arranged around the periphery of the receiving cavity, which constrains the receiving cavity. At least the upper edge of the baffle is provided with water-guiding ribs to direct water stains to both sides. This structure, utilizing the principle of "draining is worse than blocking," promptly guides any water that may have entered the top of the panel body into the door for drainage, thus helping to prevent further water intrusion into the electrical components.

[0011] Preferably, the end of the water guide bar is provided with a vertically upward-extending water-guiding bar arranged corresponding to the outer area of ​​the mounting hole. This structure facilitates the directional guidance of water flow and improves the water diversion effect.

[0012] Preferably, the rear part of the upper edge of the water-guiding rib extends downward from front to back with an inclined guiding slope. This structure can guide accumulated water at the top edge of the accommodating cavity, improving the local water diversion effect.

[0013] Preferably, a vertically extending baffle is provided in the middle of the rear side wall of the baffle at the top of the accommodating cavity. This baffle and the water-guiding rib below it together enclose a water-guiding area for relative drainage. With this structure, the water-guiding area is used to guide the accumulated water in both directions, which can quickly guide the accumulated water into the door body and improve the water diversion effect.

[0014] Preferably, the portion of the panel body located below the receiving cavity is recessed rearward to form a recessed cavity. An opening communicating with the recessed cavity is provided at the bottom of the receiving cavity, and this opening, together with the front wall of the panel body above it, constitutes a door handle. Using this structure, the door handle is directly formed on the panel door body, which is more reliable than using an additional independent component in the prior art, prevents wobbling, and provides a better user experience.

[0015] Preferably, the rear surface of the panel body corresponding to the door handle has a non-slip area with varying textures. Preferably, the non-slip area includes multiple laterally adjacent contoured grooves into which fingers can be inserted. This structure improves the user's grip comfort when opening and closing the door.

[0016] A cleaning machine includes a door and the aforementioned control panel, which is located on the top of the door.

[0017] Compared with the prior art, the advantages of this utility model are as follows: This utility model has a channel on the top wall of the panel body that connects the mounting hole and the recess. When the display screen is attached to the upper surface of the panel body, the channel, the recess, and the mounting hole remain connected. When the top of the door heats up under the influence of the washing environment, the air in the recess expands, enters the mounting hole through the channel, and is further released into the open air environment of the door through the mounting hole. The display screen is no longer subjected to the lifting force of the expanding gas. Without changing the screen structure, the problem of the display screen being easy to lift is solved, the adhesion reliability of the display screen is improved, and the intrusion of external water stains is avoided.
