Description

Technical Field

[0001] This invention relates to the field of household appliances, and particularly to a panel assembly and a household appliance using the panel assembly. Background Technology

[0002] With the development of technology, more and more intelligent home appliances have emerged. The control panel is an important part of home appliances. Users operate the control panel to make the home appliances perform corresponding actions.

[0003] For example, Chinese utility model patent ZL202123195605.5 (CN21649153U) discloses a control panel and its installation structure. The control panel includes a housing and a cover plate fitted to the housing, with control components housed within the housing. During installation, the housing is first placed in a mounting groove on a base, so that the rear end face of the mounting plate abuts against the outer wall of the base, and the mounting holes align with corresponding threaded holes. Screws are then inserted into the mounting holes and threadedly connected to the threaded holes, thus fixing the housing and base relatively. However, this installation method requires a large number of screws, affecting installation efficiency. Furthermore, because the front end of the cover plate protrudes from the front face of the housing, when the control panel is installed on a household appliance, it is fitted with the front end of the cover plate against the mounting panel on the appliance. If a panel similar to a touchscreen or display screen is mounted on the front surface of the housing, a gap exists between the panel on the front surface of the housing and the mounting panel, affecting the display and touch response. Therefore, further improvements are needed. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide a panel assembly that, while avoiding the use of screws during installation, can still stably constrain the panel and keep it in a forward-extended state.

[0005] The second technical problem to be solved by the present invention is to provide a household appliance that uses the above-mentioned panel assembly.

[0006] The third technical problem to be solved by the present invention is to provide a household appliance that uses the above-mentioned panel assembly and has a transparent panel.

[0007] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: the panel assembly includes:

[0008] panel;

[0009] The mounting bracket is located on the rear side of the panel and supports the panel, and the mounting bracket is provided with a first stop.

[0010] The mounting frame surrounds the outer periphery of the panel and is constrained together with the mounting bracket, and the mounting frame has a second stop located in front of the first stop;

[0011] Its characteristic is that it also includes:

[0012] The first elastic element is connected to the mounting frame and acts on the mounting bracket so that the first stop on the mounting bracket always tends to abut against the second stop mentioned above.

[0013] To ensure that the first stop on the mounting bracket always tends to abut against the second stop, the back of the mounting frame is provided with a slot extending in the front-rear direction for the first stop to be inserted therein. The front wall of the slot forms the second stop. The first elastic member is located on the rear side of the slot, and the first stop is located between the elastic member and the second stop.

[0014] This structure allows the panel located at the front of the mounting bracket to always remain extended, even without screws, thus maximizing its proximity to the operator for easy display or operation.

[0015] To achieve constraint between the mounting frame and the mounting bracket, the rear side of the mounting frame is provided with an internally hollow positioning bracket. The bottom wall of the positioning bracket is provided with an insertion hole extending in the front-back direction. The insertion hole communicates with the interior of the positioning bracket to form the aforementioned slot.

[0016] To improve the installation stability of the mounting bracket, there are multiple positioning brackets arranged along the periphery of the mounting frame. The number of first stops is the same as the number of positioning brackets, and they are inserted into the slots of the positioning brackets one by one.

[0017] To limit the movement of the first stop in the front-back and left-right directions, the first stop is formed by protruding outward from the outer periphery of the mounting bracket, and the insertion direction of the first stop is perpendicular to the extension direction of the insertion hole.

[0018] The structure of the first elastic element can be varied. Preferably, the first elastic element is a spring sheet disposed opposite to the panel. The spring sheet includes a first end connected to the mounting frame and a naturally extending second end. The first stop portion at least partially abuts against the second end of the spring sheet.

[0019] To enable the panel to move forward, the mounting frame is simultaneously positioned around the outer periphery of the panel and at least the front portion of the mounting bracket.

[0020] To ensure that the panel can be installed flush with the front side of the mounting frame, the front surface of the panel protrudes from or is flush with the front surface of the mounting frame when the first and second stops on the mounting bracket are in contact.

[0021] To achieve circumferential positioning of the mounting bracket, the mounting bracket includes a front side opposite to the rear surface of the panel and an extension extending rearward from the periphery of the front side, with the mounting frame surrounding the outer periphery of the extension.

[0022] To limit the vertical movement of the mounting frame, the mounting frame also includes a step extending outward from one side of the extension portion, and the back of the mounting frame is provided with an abutment portion for abutting against the step.

[0023] To improve the limiting effect, there are multiple abutment parts, which are distributed at intervals on the back of the mounting frame.

[0024] To facilitate the assembly of the positioning frame, the mounting frame is rectangular, and the positioning frame and the step are respectively located on two opposite sides of the mounting frame.

[0025] To achieve the electrical connection of the panel, a circuit board electrically connected to the panel is also included, the circuit board being installed within the mounting area enclosed by the extension.

[0026] To ensure stable installation of the mounting bracket even without screws, a second elastic element is included, acting on the mounting bracket to ensure that at least a portion of the outer periphery of the mounting bracket surrounding the mounting frame always tends to abut against the frame wall of the mounting frame. This second elastic element can act on the left, right, and / or top and bottom positions of the mounting bracket to maintain the abutment between the mounting bracket and the frame wall of the mounting frame, thereby ensuring the stability of the mounting bracket installation.

[0027] To simplify the structure, the first stop is further provided with a pressing member arranged along the front-rear direction of the mounting frame. The second elastic member abuts against the pressing member, so that the mounting frame always has the ability to move upward or downward and abut against the frame wall of the mounting frame. In this way, the pressing member and the second elastic member can abut against each other when the first stop is inserted, thereby simplifying the assembly of the structure.

[0028] Preferably, the second elastic element is a spring, which is disposed inside the positioning frame. The spring has a first end that is constrained to the top wall of the positioning frame and a second end that extends naturally downward from the first end. The second end of the second elastic element is the part where the second elastic element abuts against the surface of the pressing element.

[0029] To increase the elastic force, there are two springs. The positioning frame is also provided with two sleeves for each spring to be fitted. The top of each sleeve is constrained to the top wall of the positioning frame, and the lower end of each sleeve is also constrained with a baffle connected between the two sleeves. Each spring is constrained between the baffle and the top wall of the positioning frame. The second end of the second elastic member abuts against the pressing member through the baffle.

[0030] In order to limit the left and right directions of the mounting bracket, the mounting bracket also includes a first insert block arranged in the up and down direction. The mounting frame is provided with a first slot for inserting the first insert block. The first insert block and the first slot are inserted and locked together.

[0031] Preferably, the first insert and the first slot are substantially the same in shape and size, at least in the left-right direction.

[0032] To ensure the mounting bracket is balanced, the mounting bracket also includes at least two second inserts arranged in the vertical direction. The mounting frame has the same number of second slots as the second inserts. Each second insert is inserted into one of the second slots. When each second insert is inserted into the second slot, there is a gap between each second insert and the corresponding second slot at least one edge in the horizontal direction.

[0033] Preferably, the first insert is located in the center of the two second inserts.

[0034] Preferably, the mounting frame is rectangular, and the positioning bracket and the first slot are respectively disposed on two opposite frame walls of the mounting frame.

[0035] The technical solution adopted by the present invention to solve the second technical problem mentioned above is: the application is a household appliance with the above-mentioned panel assembly.

[0036] Preferably, the household appliance is one or more of the following: steam oven, oven, microwave oven, disinfection cabinet, range hood, and dishwasher, or an integrated combination of at least two of them.

[0037] The technical solution adopted by the present invention to solve the third technical problem mentioned above is as follows: it further includes a transparent panel for attaching to the front surface of the mounting frame. This transparent panel is typically mounted on the main body of a household appliance, and this mounting method is suitable for the installation of touchscreens.

[0038] Preferably, the panel is a display screen or a touch screen.

[0039] Compared with the prior art, the advantages of this invention are as follows: The first elastic element acts on the mounting bracket, causing the first stop on the mounting bracket to move forward and abut against the second stop under the action of elastic force. This ensures that the panel located on the front side of the mounting bracket remains in a forward-extended state, maximizing its proximity to the operator for display or operation. The structure of this panel assembly effectively reduces the number of screws, or even eliminates them, thus facilitating installation. When applied to household appliances with transparent panels, the panel, always in a forward-extended state, maintains a close fit with the overall transparent panel of the appliance, ensuring clear display and accurate operation. Especially for household appliances with touchscreen panels, the structure of this invention enables more sensitive and accurate touch operation recognition. Attached Figure Description

[0054] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0055] Example 1:

[0056] like Figures 1-7 The diagram illustrates a preferred embodiment of the panel assembly and a household appliance using the panel assembly. The household appliance can be one or a combination of at least two of the following: a steam oven, a microwave oven, a sterilizer, a range hood, and a dishwasher. In this embodiment, the household appliance is a sterilizer, such as... Figure 1 As shown, the disinfection cabinet has the following features: Figures 2-7 The panel components shown.

[0057] The panel assembly includes a panel 1, a mounting bracket 2, a mounting frame 3, and a first elastic element 4. The mounting bracket 2 is located behind the panel 1 and supports the panel 1. The panel 1 can be fixed to the front of the mounting bracket 2 by means of adhesive or other methods. The mounting bracket 2 has a first stop 21. The mounting frame 3 surrounds the outer periphery of the panel 1 and is constrained to the mounting bracket 2. The mounting bracket 3 has a second stop 31 located in front of the first stop 21. The first elastic element 4 is connected to the mounting frame 3 and acts on the mounting bracket 2 so that the first stop 21 on the mounting bracket 2 always tends to abut against the second stop 31.

[0058] When the first stop 21 and the second stop 31 on the mounting bracket 2 abut against each other, the panel 1 can be in two states: State 1, the front surface of the panel 1 is lower than the inside of the mounting frame 3; State 2, the front surface of the panel 1 protrudes from or is flush with the front surface of the mounting frame 3. State 1 is suitable for panels 1 that do not need to be attached to the entire household appliance, such as a display screen. In this way, the elastic force of the elastic sheet 4 keeps the mounting bracket 2 moving forward. Even after the panel 1 is pressed down, the force of the elastic sheet 4 keeps the panel 1 mounted on the mounting bracket 2 always exposed on the front side of the mounting frame 3, preventing it from being too close to the front. The first state allows panel 1 to be recessed into the mounting frame 3, thus ensuring that the display screen is always exposed for display. The second state is suitable for panels 1 that need to be attached to the entire home appliance, such as a touchscreen. If the mounting frame 3 is mounted on the entire home appliance or is part of the overall casing, as in this embodiment, the home appliance also includes a transparent panel 6 for attaching to the front surface of the mounting frame 3. Because the first elastic member 4 has a certain elastic deformation, while the front surface of the mounting frame 3 is attached to the transparent panel 6, the front surface of panel 1 is also attached to the transparent panel 6. This makes the touch signal sensing more sensitive and improves the user experience.

[0059] To achieve the constraints of mounting frame 3 and mounting bracket 2, such as Figure 7 As shown, the back of the mounting frame 3 is provided with a slot 32 extending in the front-rear direction for the insertion of the first stop 21. The front wall of the slot 32 constitutes the aforementioned second stop 31. The first elastic member 4 is provided on the rear side of the slot 32, and the first stop 21 is located between the elastic member 4 and the second stop 31. In this embodiment, the first elastic member 4 is a spring sheet disposed opposite to the panel 1. The spring sheet includes a first end 41 connected to the mounting frame 3 and a naturally extended second end 42. The first stop 21 at least partially abuts against the second end 42 of the spring sheet.

[0060] like Figure 5 As shown, the slot 32 is formed as follows: a hollow positioning frame 33 is provided on the back of the mounting frame 3. An insertion hole 331 extending in the front-rear direction is provided on the bottom wall of the positioning frame 33. The insertion hole 331 communicates with the interior of the positioning frame 33 to form the slot 32. In this embodiment, there are multiple positioning frames 33, arranged along the periphery of the mounting frame 3. The number of first stops 21 is the same as the number of positioning frames 33, and they are inserted one-to-one into the slots 32 of the positioning frames 33. Furthermore, the first stops 21 protrude outward from the outer periphery of the mounting frame 2, and the insertion direction of the first stops 21 is perpendicular to the extension direction of the insertion hole 331. Thus, when the first stops 21 are inserted into the slot 32, the extension direction of the insertion hole 331 and the insertion direction of the first stops 21 can limit the movement of the first stops 21.

[0061] The mounting frame 3 is simultaneously surrounding the outer periphery of the panel 1 and at least the outer periphery of the front portion of the mounting bracket 2, so that when the first elastic member 4 acts on the first stop 21, the front surface of the panel 1 protrudes from or is flush with the front surface of the mounting frame 3.

[0062] In this embodiment, as Figure 4 As shown, the mounting bracket 2 includes a front side 22 opposite to the rear surface of the panel 1 and an extension 23 extending rearward from the periphery of the front side 22. A mounting frame 3 surrounds the outer periphery of the extension 23. Preferably, the front side 22 is adapted to the panel 1 and is rectangular. The shape of the extension 23 is adapted to the opening 35 in the center of the mounting frame 3, thus limiting the peripheral wall of the extension 23 by the mounting frame 3. Additionally, the mounting bracket 2 includes a step 24 extending outward from one side of the extension 23, and the back of the mounting frame 3 has an abutment 34 for abutting against the step 24. Figure 5 As shown, there are multiple abutment portions 34, which are distributed at intervals on the back of the mounting frame 3. In this embodiment, the abutment portion 34 is cylindrical, but it can also be other shapes.

[0063] Furthermore, the mounting frame 3 is rectangular, and the positioning bracket 33 and the abutment part 34 are respectively located on two opposite sides of the mounting frame 3. Figure 5 As shown, the positioning bracket 33 is located at the upper back of the mounting frame 3, and the abutment part 34 is located at the lower back of the mounting frame 3. This makes it easy for the first stop 21 on the mounting bracket 2 to be inserted into the positioning bracket 33. At the same time, the abutment part 34 limits the positioning bracket 33 in the vertical direction. Therefore, the panel assembly does not need to be installed with screws, which is convenient for disassembly and assembly. Moreover, the first stop is not easy to fall off due to the elastic force, which can ensure the stability of the installation.

[0064] Example 2:

[0065] like Figures 8-14 As shown, unlike in Embodiment 1, this embodiment also includes a second elastic member 71 acting on the mounting bracket 2, so that at least a portion of the outer periphery of the mounting bracket 2 surrounding the mounting frame 3 always tends to abut against the frame wall of the mounting frame 3. Thus, the elastic force of the second elastic member 71 maintains the stability of the mounting bracket 2, eliminating the need for screws and making the installation of the mounting bracket 2 more convenient.

[0066] To keep the structure simple, such as Figure 11 and Figure 12As shown, in this embodiment, the first stop 21 is also provided with a pressing member 25 arranged along the front-rear direction of the mounting frame 2. The second elastic member 71 abuts against the pressing member 25 so that the mounting frame 2 always has the ability to move upward or downward and abut against the frame wall of the mounting frame 3. In this way, the mounting frame 2 can be kept stable by limiting its vertical movement. Of course, it can also be changed to limit its horizontal movement according to actual installation needs.

[0067] In this embodiment, the second elastic element 71 is a spring, which is disposed within the positioning frame 33. The spring has a first end that is constrained to the top wall of the positioning frame 33 and a second end that extends naturally downward from the first end. The second end of the second elastic element 71 serves as the part where the second elastic element 71 abuts against the surface of the pressing member 25. This facilitates the installation of the second elastic element 71 and increases the force acting on the pressing member 25. Figure 14 As shown, there are two springs in this embodiment. The positioning frame 33 is also provided with two sleeves 72 for each spring to be fitted. The top of each sleeve 72 is constrained to the top wall of the positioning frame 33, and the lower end of each sleeve 72 is also constrained to a baffle 73 connected between the two sleeves 72. Each spring is constrained between the baffle 73 and the top wall of the positioning frame 33. The second end of the second elastic member 71 abuts against the pressing member 25 through the baffle 73.

[0068] To facilitate the assembly of the mounting bracket 2, the mounting bracket 2 also includes a first insert 26 arranged vertically. The mounting frame 3 has a first slot 36 for inserting the first insert 26. The first insert 26 and the first slot 36 are interlocked and locked together. The first insert 26 and the first slot 36 are substantially the same in shape and size, at least in the left-right direction. This allows the mounting bracket 2 to be positioned both horizontally and vertically through the cooperation of the first insert 26 and the first slot 36. Figure 10 As shown, in this embodiment, the first insert block 26 is an isosceles trapezoid.

[0069] In addition, the mounting bracket 2 also includes at least two second inserts 27 arranged in the vertical direction, and the mounting frame 3 has the same number of second slots 37 as the number of second inserts 27. Each second insert 27 is inserted into one of the second slots 37. When each second insert 27 is inserted into the corresponding second slot 37, a gap 270 is left between each second insert 27 and the corresponding second slot 37 at least one edge in the horizontal direction. Figure 10 As shown, in this embodiment, the second insert 27 is square, and the second slot 37 is also square. And as... Figure 9 and Figure 10As shown, the first insert 26 is located in the center of the two second inserts 27. The purpose of the second inserts 27 and the second slot 37 is mainly to ensure the installation balance at all points at the lower end of the mounting bracket 2, so as to prevent the mounting bracket 2 from shifting due to the lack of constraint in other positions caused by relying solely on the first insert 26. Furthermore, the gap 270 allows the mounting bracket 2 to maintain a certain movement gap after the first insert 26 is installed in place, which facilitates the installation and removal of the mounting bracket 2.

[0070] like Figure 10 As shown, the mounting frame 3 is rectangular, and the positioning brackets 33 and the first slots 36 are respectively located on two opposite frame walls of the mounting frame 3. There are three positioning brackets 33, which are respectively located on the upper frame wall of the mounting frame 3; there is one corresponding first slot 36, which is located on the frame wall below the central positioning bracket 33; there are two second slots 37, which are respectively located on the frame walls below the left and right positioning brackets 33.

[0071] The installation process of the panel assembly in this embodiment is as follows:

[0072] Insert the first stop 21 into the slot 32 from bottom to top, and make the pressing member 25 abut against the stop plate 73. Under the action of external force, the mounting bracket 2 moves upward continuously. At this time, the pressing member 25 continuously compresses the second elastic member 71 (spring). When the first insert 26 at the lower end of the mounting bracket 2 is at least higher than the top of the first slot 36, it can enter the first slot 36 from the notch adjacent to the second slot 36 (e.g. Figure 11 As shown), when the external force disappears, the second elastic element 71 acts on the pressing element 25, causing the pressing element 25 to move downwards and the entire mounting frame 2 to move downwards. Finally, the first insert block 26 is inserted into the first slot 36, and at least part of the outer periphery of the mounting frame 2 surrounding the mounting frame 3 abuts against the frame wall of the mounting frame 3 (as shown). Figure 12 As shown in the figure, this means that the assembly of the mounting bracket 2 and the mounting frame 3 can be achieved without screws.

[0073] On the other hand, when the first elastic member 4 acts on the first stop 21, the front surface of the panel 1 protrudes from or is flush with the front surface of the mounting frame 3.

[0074] The specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
