Description

Technical Field

[0001] This application relates to the field of control panel installation technology, specifically to a control panel component and its installation method, and cooking equipment. Background Technology

[0002] To meet user needs, kitchen appliances such as steam ovens and regular ovens have emerged on the market that require no user intervention during the cooking process. For example, a steam oven works by continuously supplying high-temperature steam to the inner cavity containing the food, thus cooking it through pure steaming. An oven, on the other hand, works by continuously supplying circulating hot air to the inner cavity containing the food, thus cooking it through hot air baking. Meanwhile, due to limitations such as apartment layout, current kitchens typically use built-in installations, such as installing cooking appliances in lower kitchen cabinets.

[0003] Taking ovens as an example of cooking appliances, a control panel is typically located on the front of the oven for displaying and interacting with cooking-related functions. For built-in ovens, a common configuration for the control panel is that it's screwed onto the back of the unit. This means that to repair the control panel, the oven must be pulled out of the cabinet, and the screws on the back of the control panel must be unscrewed. Another configuration uses screws on the bottom of the control panel. Compared to the rear-mounted design, this allows for easy removal by simply pulling the oven forward a shorter distance. However, the bottom-mounted design lacks a fixing element at the top of the control panel, causing it to wobble during interactive actions such as pressing, directly impacting the user experience. Furthermore, this structure can also affect the oven's reliability to some extent. Summary of the Invention

[0004] This application aims to solve at least part of the above-mentioned technical problems and / or at least part of the above-mentioned technical problems, specifically, how to improve the user experience for control panel maintenance operations.

[0005] In a first aspect, this application provides a control panel assembly comprising: a control panel including a first panel portion near the top and a second panel portion near the bottom; a control panel bracket fixedly connected to the second panel portion by means of fasteners; and a panel glass disposed on the control panel; wherein the control panel assembly further comprises: a connecting member, which is fixedly disposed on the first panel portion on one hand, and in the assembled state, on the other hand, is capable of abutting against the panel glass based on the deformation generated by the connecting member.

[0006] This design ensures the reliability of the control panel components. Specifically, the fixed connection at the bottom improves installation convenience. Furthermore, the design of the connecting components guarantees stability during interactive operations, improves the user experience, and ensures the structural reliability of the control panel components.

[0007] It is understood that those skilled in the art can determine the specific structural form of the first / second panel portion, the way they constitute the control panel, the structural form / material of the connecting member, the position / form of the fixed connection between the connecting member and the first panel portion, and the specific method of abutting between the connecting member and the panel glass, etc., according to actual needs. For example, the first / second panel portion can be a plate-like structure, a cover-like structure, etc., and the connecting member can be fixedly connected to the first panel portion by direct connection (such as bonding) or indirect connection (such as by introducing an intermediate component, fixing the connecting member to the first panel portion, and fixing the connecting member to the intermediate component). If the connecting member is a thin sheet structure, it can deform during installation and achieve abutment. Elastic materials can also be used in some or all areas, achieving abutment through the deformation of the elastic material. For example, the connecting member can include one or more components, which can be separately installed, connected to each other, or integrally formed.

[0008] In one possible implementation of the control panel assembly described above, the connecting member includes: a first connecting portion disposed on the first panel portion; and a second connecting portion, at least a portion of which is made of an elastic material, the second connecting portion being able to abut against the panel glass, and in the abutting state, the second connecting portion having a compression amount along the thickness direction of the panel glass.

[0009] With this configuration, it is possible to achieve contact between the second connecting part and the panel glass through the deformation of the elastic material.

[0010] It is understood that those skilled in the art can determine the specific material of the second connecting part, the structural form of the first / second connecting part, and the specific way in which the first / second connecting part constitutes the connecting member, etc., according to actual needs. For example, all or part of the second connecting part is made of elastic material, and the first / second connecting part can be directly connected, indirectly connected, integrally formed, etc.

[0011] In one possible implementation of the control panel assembly described above, the first panel portion includes: a first vertical portion; a second vertical portion; and a horizontal portion disposed between the first vertical portion and the second vertical portion; wherein the first vertical portion, the second vertical portion, and the horizontal portion form a mounting cavity capable of accommodating the upper portion of the control panel bracket; wherein the first connecting portion is adhesively fixed to the side of the first vertical portion away from the panel glass.

[0012] This configuration provides a possible structural form for the first panel section.

[0013] In one possible implementation of the control panel assembly described above, when viewed along the thickness direction of the panel glass, there is a gap between the first connecting portion and the second connecting portion.

[0014] This configuration prevents the second connecting portion from rubbing against the control panel during installation onto the control panel bracket. Specifically, the second connecting portion, which abuts against the panel glass (and interferes with the panel glass in the thickness direction due to the compression), is located on the outer side, while the first connecting portion, which is bonded to the control panel, is located on the inner side, forming a stepped surface between the two.

[0015] In one possible implementation of the control panel component described above, the first connecting portion comprises an elastic material; and / or the first connecting portion and the second connecting portion are integrally formed; and / or the allowable compression of the second connecting portion is determined according to the manufacturing tolerances of the sheet metal design.

[0016] This configuration illustrates possible structural forms for the connecting member. For example, the first and second connecting portions are integrally formed and both are made of an elastic material that allows for a predetermined amount of compression. It is understood that those skilled in the art can determine the allowable amount of compression based on the manufacturing tolerances of the actual sheet metal design. For instance, based on the manufacturing tolerances of the resulting sheet metal design, the material, thickness, and other specifications of the second connecting portion can be adjusted to ensure that the allowable amount of compression meets the installation requirements of the control panel assembly.

[0017] In one possible implementation of the control panel component described above, the second vertical portion includes or extends a first guide portion near the bottom.

[0018] This design ensures ease of installation from above. For example, the first guide section can be an inclined surface, a curved surface, etc.

[0019] In one possible implementation of the control panel assembly described above, the control panel bracket includes or extends a second guide portion on the side near the panel glass.

[0020] This design ensures ease of installation below after installation above. Similar to the first guide section, the first guide section can be an inclined surface, a curved surface, etc.

[0021] In a second aspect, this application provides a cooking device that includes the control panel component described in any of the preceding claims.

[0022] It is understood that the cooking device has all the technical effects of the control panel components described in any of the foregoing descriptions, and will not be repeated here.

[0023] In one possible implementation of the above-mentioned cooking equipment, the cooking equipment includes a housing, and the control panel bracket is fixedly connected to the housing on the back side.

[0024] With this configuration, the control panel can be configured on the cooking device by connecting it to the control panel at the bottom and by fixing it to the cabinet on the back side. Similar to the bottom, the back side is also fixed to the cabinet using fasteners such as screws.

[0025] In a third aspect, this application provides a method for installing a control panel assembly, the control panel assembly including a control panel, a control panel bracket, a panel glass, and a connecting member, the control panel including a first panel portion near the top and a second panel portion near the bottom, the installation method including: fastening the first panel portion to the control panel bracket near the top; moving the second panel portion to a position near the bottom of the control panel bracket, such that: accompanying the movement of the first panel portion at the position corresponding to the upper position of the control panel bracket, the control panel reaches a position where it is installed with the control panel bracket; and fixing the second panel portion to the control panel bracket; wherein, when installed, the connecting member fixedly disposed on the control panel abuts against the panel glass.

[0026] This design ensures the stability of the control panel while maintaining a fixed connection at the bottom, effectively preventing the glass panel from shaking during interaction and thus improving the user experience.

[0027] It is understood that the installation method of this control panel component has all the technical effects of the control panel component described in any of the foregoing items, and will not be repeated here.

[0028] Furthermore, it should be understood that the structure involved in the installation method of the control panel components is not limited to the structure of the control panel components described in any of the foregoing items. Specifically, provided that the installation logic is satisfied, appropriate changes can be made to the structure of the control panel components described in any of the foregoing items.

[0048] Preferred embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application. For example, although this embodiment describes cooking equipment in conjunction with an oven, this is not intended to limit the scope of protection of this application. Without departing from the principles of this application, those skilled in the art can apply this application to other application scenarios such as steam ovens and steam-oven combos.

[0049] It should be noted that in the description of this application, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" 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 direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0051] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can still be implemented without certain specific details. In some examples, the structural forms and principles of steam ovens well known to those skilled in the art are not described in detail, in order to highlight the main points of this application.

[0052] The following will refer to the appendix. Figures 1 to 6 This application shall be described in at least a portion thereof.

[0053] Main reference Figure 1 and Figure 5 In one possible implementation, the oven mainly includes a cooking body and a control panel assembly 100. The cooking body mainly includes a cabinet and an inner liner disposed within the cabinet. The control panel assembly 100 is fixedly disposed within the cabinet. The inner liner forms a cooking chamber for holding food to be cooked. For example, a shelf can be provided inside the inner liner, and the food to be cooked can be placed directly on the shelf or placed on a container (such as a plate) placed on the shelf.

[0054] In one possible implementation, the control panel assembly 100 is located on the side of the oven housing facing the operator (e.g., the front side). The oven is installed in the kitchen in a recessed manner. Exemplarily, the oven is installed in a kitchen cabinet below the cooktop.

[0055] In one possible implementation, the control panel assembly 100 mainly includes a control panel 1, a control panel bracket 2, a connecting member 3, and a panel glass 4. The panel glass 4 is disposed on the control panel 1, the control panel 1 is disposed on the control panel bracket 2, and the control panel bracket 2 is disposed on the housing. The control panel 1 includes a first panel portion 11 near the top and a second panel portion 12 near the bottom. The second panel portion 12 is provided with a first mounting hole (mounting hole) 101. The second panel portion 12 and the lower portion of the control panel bracket 2 are fixedly connected vertically at the bottom by means of fasteners such as screws engaging with the mounting hole. The connecting member 3 is capable of a certain degree of deformation. On the one hand, the connecting member 3 is fixedly disposed on the upper first panel portion 11; on the other hand, it can reliably abut against the inner wall of the panel glass 4 in the assembled state of the control panel assembly 100.

[0056] For example, a second mounting hole 201 is also provided on the back side of the control panel bracket 2. The entire control panel assembly 100 is fixedly connected to the housing by means of fasteners such as screws and the second mounting hole 201. Based on this, when maintenance work on the control panel 1 is required, the control panel 1 can be removed from the control panel bracket 2 by simply pulling the oven out of the kitchen cabinet a short distance, thereby completing the relevant maintenance work. Furthermore, the stability of the control panel assembly 100 can be ensured by the setting of the connecting member 3.

[0057] In one possible implementation, the connecting member 3 includes a first connecting portion 31 and a second connecting portion 32. The first connecting portion 31 is fixedly disposed on the first panel portion 11, and the second connecting portion 32 is deformable and can abut against the inner wall of the panel glass 4 in the assembled state. In this example, both the first connecting portion 31 and the second connecting portion 32 are elastic foam pads and are integrally formed. The first connecting portion 31 and the second connecting portion 32 have a gap along the horizontal direction (the thickness direction of the panel glass 4), such that they roughly form a stepped surface. The first connecting portion 31 is fixedly disposed on the first panel portion 11 by adhesive bonding, and the second connecting portion 32, when abutting against the inner wall of the panel glass 4, will generate a certain amount of compression along the thickness direction of the panel glass 4.

[0058] In one possible implementation, the first panel portion 11 is generally U-shaped, and the second panel portion 12 is generally planar. The first panel portion 11 mainly includes a first vertical portion 111, a second vertical portion 112, and a horizontal portion 113 located between them. The first vertical portion 111, the second vertical portion 112, and the horizontal portion 113 form a mounting cavity capable of accommodating the upper portion of the control panel bracket 2. The U-shaped structure can be snapped into the mounting cavity of the upper portion of the control panel bracket 2, and also allows for a certain amount of rotation (primarily rotational movement).

[0059] In one possible implementation, a first guide portion 51 extends from the lower part of the second vertical portion 112, thereby facilitating the smooth attachment of the first panel portion 11 of the control panel 1 to the upper part of the control panel bracket 2. In this example, the first guide portion 51 is approximately a sloped surface inclined downwards / inwards at 30° (the angle with the vertical direction). Obviously, the angle of inclination can be flexibly adjusted according to actual needs, such as being flexibly selected between 15-45°. In addition, the sloped surface can also be changed to other structural forms with guiding functions, such as curved surfaces.

[0060] In one possible implementation, the lower part of the control panel bracket 2 is generally planar, with a second guide portion 52 extending from the end of the planar structure near the panel glass 4. This facilitates the smooth pushing of the second panel portion 12 of the control panel 1 into place along the lower part of the control panel bracket 2. Similar to the first guide portion 51 in this example, the second guide portion 52 is approximately an upward / outward inclined surface at a 30° angle (towards the horizontal direction). Clearly, those skilled in the art can flexibly adjust its structural form according to actual needs.

[0061] In one possible implementation, heating elements such as heating tubes are provided on the inner top, inner sides, and inner bottom of the inner pot to provide primary or auxiliary / supplementary heating of the cooking medium (hot airflow) within the cooking chamber when needed. Furthermore, an openable door assembly is provided on the front side of the cooking body. Exemplarily, both the control panel assembly 100 and the door assembly are located on the cooking body, with the control panel assembly 100 positioned above the door assembly.

[0062] In one possible implementation, the oven typically includes a fan shroud assembly primarily used to provide circulating hot airflow into the cooking chamber. The fan shroud assembly mainly includes a centrifugal fan (such as a temperature-regulating fan) and a heating element such as a heating coil. The temperature-regulating fan is primarily used to maintain the temperature of the hot airflow within the cooking chamber as uniformly and consistently as possible. Exemplarily, the fan shroud assembly includes a hot air chamber formed between the fan shroud and the back panel of the cooking body for housing the centrifugal fan. The heating element, such as the heating coil, can be located within the hot air chamber or at other locations near the hot air chamber. Taking a heating coil as an example, the heating coil can be located within the hot air chamber, and the centrifugal fan can be located within the area enclosed by the heating coil. The fan shroud has a return air vent near the centrifugal fan, and also has an air supply vent, such as the air supply vent positioned approximately circumferentially around the return air vent or at a partial circumferential location. For example, a centrifugal fan includes a motor and a fan. The motor drives the fan to rotate facing the return air vent. The fan's rotation draws air from the inner cavity into the hot air chamber through the return air vent. For instance, a heating coil is positioned within the hot air chamber corresponding to the return air vent, and the fan is positioned within the area enclosed by the heating coil. Thus, under the action of the centrifugal fan, air from the inner cavity is drawn into the hot air chamber through the return air vent, heated by the heating coil, and converted into a hot airflow carrying heat, serving as a cooking medium. The fan then propels the hot airflow towards the outer air outlet and back into the inner cavity. This cycle continuously delivers hot airflow to the surface of the food to be cooked, allowing the food to be cooked using a hot air baking method according to a corresponding control program. The oven also includes a heat dissipation component, which may include a heat dissipation duct and a heat dissipation fan. The heat dissipation fan primarily draws air out through the heat dissipation duct, thereby dissipating heat from components such as the power board, electrical components, the aforementioned door assembly, and the control panel assembly 100 to ensure the reliable operation of the cooking equipment.

[0063] As can be seen, in the preferred embodiment of this application, the control panel 1 is connected to the control panel bracket 2 at its bottom. When maintenance of the control panel 1 is required, the oven can simply be pulled out a short distance from the kitchen cabinet. Furthermore, the connection member 3 ensures the overall structural stability of the control panel assembly 100, preventing wobbling when pressing the panel glass 4 and improving the user experience.

[0064] Based on the above structure, mainly refer to Figure 6 In one possible implementation, this application also provides a method for installing a control panel component, mainly used to install the control panel component on an oven. For example, during the manufacturing process or after maintenance work on the control panel, the control panel is installed onto the oven using the following method. The installation method mainly includes the following steps:

[0065] S610. Apply external force to fasten the upper first panel portion 11 to the upper outer side of the control panel bracket 2.

[0066] S620. Apply external force to move the lower second panel portion 12 towards the lower part of the control panel bracket 2.

[0067] During this process, the upper first panel portion 11 will rotate a certain amount relative to the upper position of the control panel bracket 2, and the control panel 1 will be pulled down as a whole until the control panel 1 and the control panel bracket 2 are installed in place. At the same time, the connecting member 3 abuts against the inner side of the panel glass at the position of the second connecting part 32.

[0068] S630. With the device in place, the control panel 1 and the control panel bracket 2 are fixedly connected from below by means of fasteners such as screws and mounting holes.

[0069] As can be seen, the process of installing the control panel 1 (with the panel glass 4 already fixedly mounted on the control panel 1) onto the control panel bracket 2 is roughly as follows:

[0070] First, the upper first panel portion 11 is smoothly fastened onto the exterior of the control panel bracket 2 near the top, guided by the first guide portion 51. At this time, since the elastic foam strip is attached to the step difference position between the control panel 1 and the panel glass 4 (first connecting portion 31), the cross-section of the elastic foam strip (second connecting portion 32) will not be rubbed during installation, thus ensuring the convenience and reliability of installation.

[0071] After the first panel portion 11 is fastened to the outer side of the control panel bracket 2 near the upper part, a force is applied to the control panel 1 that causes it to rotate downwards approximately around the installed portion (mainly rotation, but in fact, a combined motion including rotation). At this time, the installed portion on the upper side can be considered the pivot side, and the lower side of the control panel 1 (the second panel portion) is the free side. In this way, the lower second panel portion 12 can move towards the lower part of the control panel bracket 2 under the action of the external force. Based on this movement, the second panel portion 12 can slide into the lower outer side of the control panel bracket 2 guided by the second guide portion 52. If the rotation of the control panel 1 continues to push inwards past the second guide portion 52, the control panel 1, which is already somewhat constrained to the control panel bracket 2 above, can be pulled downwards as a whole, thereby achieving proper installation between the upper part of the control panel 1 and the control panel bracket 2. At this time, a certain amount of compression is formed between the control panel bracket 2 and the second connecting portion 32 of the elastic foam strip.

[0072] When the oven control panel needs repair, simply pull the oven out a short distance from the kitchen cabinet, and the control panel can be removed from the control panel bracket from below (first mounting hole), improving the user experience during repairs. Once the repairs are complete, the control panel can be easily and reliably reinstalled using the aforementioned installation method.

[0073] In a specific example, the thickness of the elastic foam strip is 1mm, and the compression of the elastic foam strip in the assembled state of the control panel assembly 100 is 0.5mm. In typical sheet metal designs, due to manufacturing tolerances, a certain installation gap exists between the control panel 1 and the control panel bracket 2. This installation gap can cause wobbling when pressing the panel glass 4 (especially near the top). By adopting this application, the problems of unreliable installation or even inability to install due to manufacturing tolerances can be effectively avoided. With installation reliability guaranteed, the wobbling phenomenon can be effectively avoided, thereby ensuring installation stability and improving the user experience.

[0074] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
