Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a control panel, door structure, and household appliance for use in household appliances. Background Technology

[0002] For household appliances with functional cavities, such as dishwashers, steam ovens, and ovens, a door is usually installed at the opening of the appliance to allow it to be opened or closed, due to functional requirements. The door typically opens by rotating forward or backward, and a handle is required on the front of the door for easy opening and closing. To improve aesthetics and ease of use, some dishwashers now also have lights installed on the door.

[0003] For example, the Chinese utility model patent application CN202322993065.8 (publication number CN221635685U) discloses an "Automatic Interactive Dishwasher Door," which includes a frame. The bracket is provided on the inner side of the frame. An upper door panel and a lower door panel are provided on the front side of the frame. The upper door panel and the lower door panel are respectively located on the upper and lower sides of the bracket. A recessed handle groove is provided on the front side of the bracket. The handle groove includes a light-transmitting top wall. An ambient light is provided above the bracket, facing the top wall of the handle groove. A human body sensor is provided on the front side of the bracket. The sensing end of the human body sensor faces the front of the frame. The human body sensor and the ambient light are electrically connected to the controller of the dishwasher. The controller is used to control the ambient light to light up when the human body sensor senses a human body.

[0004] In this patent, the ambient light is directed towards the top wall of the handgrip recess. To reduce light absorption, the surface on which the light is projected (such as the top wall of the handgrip recess) is usually white. Since some brackets are molded in one piece, the entire bracket would be white. However, a white appearance doesn't match the kitchen well, thus affecting customer purchase rates. If the bracket uses other colors, such as black, it would match the kitchen better, but black absorbs light, resulting in poor lighting performance.

[0005] In addition, the top of the frame is equipped with a top touch screen, which means that users can operate the cleaning equipment from the top of the dishwasher. However, some dishwasher models on the market can be operated from the front (i.e., the front wall).

[0006] For these two different models, two different molds are usually needed to produce the corresponding control panels, which increases the product development cost. Utility Model Content

[0007] The first technical problem this invention aims to solve is to provide a control panel for household appliances that offers good lighting effects and is easy to match with existing technologies.

[0008] The second technical problem to be solved by this utility model is to provide a door structure for household appliances that applies the above-mentioned control panel, in view of the current state of the prior art.

[0009] The third technical problem to be solved by this utility model is to provide a household appliance that applies the above-mentioned door structure, in view of the current state of the prior art.

[0010] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: a control panel for household appliances, including a frame and a decorative panel, wherein the front wall of the frame is partially recessed to form a cavity, a lamp body is installed on the frame above the cavity, the bottom wall of the cavity is located on the light path of the lamp body, the decorative panel is attached to the front wall of the frame and located above the cavity, and a white and light-transmitting element is provided on the bottom wall of the decorative panel, the light-transmitting element is located on the reflection path of light from the bottom wall of the cavity.

[0011] In order to ensure that light can be well reflected onto the light-transmitting element, the light-transmitting element is located directly in front of the concave cavity.

[0012] Preferably, the light-transmitting element is white, as white has poor light absorption and does not absorb much light.

[0013] Preferably, the recessed cavity extends through the frame in the left-right direction, which can achieve the effect of thinning the door body.

[0014] To facilitate applying force to the door to open or close it, the frame is provided with a handle groove, the bottom of which is open and faces a recessed cavity. The handle groove is located directly in front of the light fixture. In this way, the handle groove is hidden within the frame, and the light fixture is concealed behind it, improving the aesthetics of the door structure.

[0015] Preferably, the bottom wall of the cavity is a concave arc surface, which enhances the user's finger joint experience when reaching out to open the door.

[0016] In the above solution, the frame includes a frame body and a handle component. The handle groove is provided on the handle component. The frame body is provided with an installation area. The handle component is installed in the installation area. The bottom wall of the installation area has an opening for the handle groove to be exposed.

[0017] In order to reduce the product development cost, the installation area is also equipped with a switch for controlling the working process and working parameters of household appliances, and the front wall of the frame is provided with a first through hole for exposing the control position of the switch.

[0018] The top wall of the frame is provided with a second through hole for exposing the control points of the switch components, or the top wall of the frame is a strip plate without holes. The only difference between the control panels of these two models lies in the structure of the top wall of the frame. When developing the mold, only two models of the top wall plate need to be developed, and both of these different top wall plates can be detachably connected to the main body of the mold. When manufacturing the control panel, only the different top wall plates of the mold need to be installed on its main body to manufacture control panels with different structures, greatly reducing mold development costs and eliminating the need to create two sets of molds.

[0019] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a door structure for household appliances, characterized in that: it includes a door body and the aforementioned control panel, wherein the control panel is located at the top of the door body and the two are fixed together.

[0020] The technical solution adopted by this utility model to solve the third technical problem mentioned above is: a household appliance, characterized in that it includes a cabinet and the aforementioned door structure, the front side of the cabinet is open, and the door structure is movably disposed at the open side of the cabinet, thereby opening or closing the open side.

[0021] The household appliance can be a front-opening steam oven, oven, refrigerator, etc., or it can be a dishwasher.

[0022] Compared with existing technologies, the advantages of this utility model are as follows: By setting a white, translucent light-transmitting element at the bottom of the decorative panel, the light projected by the lamp body is ultimately reflected onto the light-transmitting element, without affecting the final lighting atmosphere of the lamp body.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] In the description of this utility model patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an adhesive connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model patent based on the specific circumstances.

[0038] The household appliance in this preferred embodiment is a dishwasher, but it can also be a front-opening steam oven, oven, refrigerator, etc.

[0039] like Figures 1-12 As shown, the household appliance includes a cabinet (not shown in the figure) and a door structure. The front of the cabinet is open, and the door structure is movably located at the opening of the cabinet, thereby opening or closing the opening. The cabinet and door structure can be connected using existing rotating connections, which will not be described in detail here.

[0040] The door structure includes a door body 1 and a control panel 2. The control panel 2 is located at the top of the door body 1 and the two are fixed together. Specifically, the control panel 2 includes a frame 21 and a decorative panel 22. The frame 21 extends downward in a portion to form a connecting part 2a. The connecting part 2a is located on the rear side of the door body 1 and the two are fixed together by screws or other connectors.

[0041] The front wall of frame 21 is partially recessed to form a cavity 23. In this embodiment, the cavity 23 only has a top wall and a bottom wall. Of course, the cavity 23 can also be U-shaped, including a top wall, a side wall, and a bottom wall. The cavity 23 extends through frame 21 in the left-right direction, which can achieve the effect of thinning the door body 1.

[0042] A lamp body (such as an LED lamp) is mounted on the frame 21 above the cavity 23. Figure 3 , 10 As shown, the frame 21 has a mounting groove 24 with an open bottom. The opening of the mounting groove 24 faces downward and is aligned with the cavity 23. The lamp body is installed in the mounting groove 24. A light diffuser 25 is installed at the opening of the mounting groove 24 to evenly project light onto the cavity 23. Of course, the light diffuser 25 may not be provided.

[0043] The bottom wall of the recess 23 is located on the light path of the lamp body. The decorative panel 22 is attached to the front wall of the frame 21 and located above the recess 23. The bottom wall of the decorative panel 22 is provided with a white, translucent light-transmitting element, which is located on the reflection path of light from the bottom wall of the recess 23. White has poor light absorption and does not absorb much light.

[0044] In this embodiment, the decorative panel 22 is a glass plate, and the light-transmitting element is located directly in front of the recessed cavity 23, so that light can be well reflected onto the light-transmitting element. The light-transmitting element can be a white light-transmitting strip attached to the bottom wall of the decorative panel 22; or the light-transmitting element can be the bottom wall of the decorative panel 22 directly, and the bottom wall of the decorative panel 22 is white; or, a layer of white light-transmitting adhesive can be applied to the bottom wall of the decorative panel 22.

[0045] To further enhance the ambiance, both the lamp body and the light-transmitting components extend in the left and right directions, allowing users to see strips of light, resulting in a good atmosphere and aesthetic appeal.

[0046] The light projected by the lamp body is ultimately reflected onto the light-transmitting component, without affecting the final lighting atmosphere of the lamp body. Users standing in front of the home appliances can clearly observe the illuminated area of ​​door 1. Thus, the frame 21 can be a color that complements other colors in the kitchen, such as black, solving the problem of a black frame 21 absorbing light and causing it to weaken, thus affecting the lighting effect. Furthermore, the light-transmitting component illuminates the lower edge of the decorative panel 22, improving the user experience.

[0047] To facilitate the application of force to the door 1 for opening or closing, a handle groove 26 is provided on the frame 21. The bottom of the handle groove 26 is open and faces the cavity 23, and the handle groove 26 is located directly in front of the lamp body. In this way, the handle groove 26 is hidden in the frame 21, and the lamp body is hidden behind the handle groove 26, improving the aesthetics of the door structure and making the structure compact. Both the handle groove 26 and the mounting groove 24 penetrate through the top wall of the cavity 23.

[0048] The front wall of the handle groove 26 is a wavy curved surface to improve the user's finger contact experience. The bottom wall of the cavity 23 is a concave arc surface 231, which enhances the user's finger joint experience when reaching out to open the door. In addition, the cavity 23 has an flared structure from back to front, increasing the space and making it easier for the hand to reach in.

[0049] In this embodiment, as Figure 6 , 7 As shown, the frame 21 includes a body 27 and a handle 28. A handle groove 26 is provided on the handle 28. The body 27 has a mounting area 271, and the handle 28 is installed in the mounting area 271. The bottom wall of the mounting area 271 has an opening 272 for exposing the handle groove 26 and the mounting slot 24. Of course, the handle 28 can also be integrally formed on the body 27.

[0050] The installation area 271 also includes a switch 4 for controlling the operation and parameters of household appliances. The front wall of the frame 27 has a first through hole 291 for exposing the control points of the switch 4 and a third through hole 292 for mounting the display 5. The top wall of the frame 27 has a second through hole 201 for exposing the control points of the switch 4 and a fourth through hole 202 for mounting the display 5. Alternatively, the top wall of the frame 27 can be a non-perforated strip.

[0051] The only difference between the control panel 2 of these two models is the different top wall structure of the frame 27. When developing the mold, only two models of the top wall plate of the mold need to be developed. Then, the two different models of the top wall plate can be detachably connected to the main body of the mold. When manufacturing the control panel 2, only the different top wall plates of the mold need to be installed on its main body to manufacture control panel 2 with different structures, which greatly reduces the mold development cost and eliminates the need to open two sets of molds.

[0052] Figures 1-7 The control panel 2 shown has the following structure: the top wall of the frame 27 is a strip without holes. In this model, the user operates the control panel 2 from the front. The decorative panel 22 may be equipped with touch keys for the user to touch to trigger the switch 4. This is a very common technology nowadays and will not be described in detail here.

[0053] Figures 8-12 The control panel 2 shown has the following structure: a second through hole 201 is provided on the top wall of the frame 27 for exposing the control position of the switch 4. In this model, the user operates the top wall of the control panel 2, meaning the first through hole 291 on the front wall of the frame 27 for exposing the control position of the switch 4 is not used. A glass plate 6 can be installed on the top of the control panel 2, with a touch key on the glass plate 6 for the user to touch to trigger the switch 4. This is a very common technology and will not be described in detail here.

[0054] In this embodiment, the structure of the switch 4 is based on existing technology.
