[0026] The utility model is further described in detail below based on the accompanying drawings and implementation cases.

[0027] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0028] A control device is used to control an electrical appliance. A user controls the appliance by rotating and pressing. A display 4 is provided on the top of the control device 1. Information of the two operation modes of the user is displayed on the display 4.

[0029] The control device of this embodiment can be used in kitchen appliances. By connecting the control device to the kitchen appliances in a communication connection manner, for example, an integrated stove, a steam oven, a dishwasher, etc. can be communicatively connected.

[0030] In this implementation case, refer to Figure 1-Figure 4 The display 4 has a flat main structure 4-1 and at least one support structure 4-2 formed on the bottom surface of the main structure 4-1. The control device 1 is a cylindrical structure in the overall frame structure, and has a circular opening on the top, so that the internal structure of the control device 1 can be installed into the inside of the control device 1 through the top opening. The main structure 4-1 of the display 4 is installed on the top of the control device 1, and the outer peripheral part of the bottom surface of the main structure 4-1 fits on the edge of the top opening of the control device 1, so that the main structure 4-1 closes the top opening of the control device 1. The support structure 4-2 extends from the top opening of the control device 1 into the inside of the control device 1, and the support structure 4-2 is supported by the internal structure of the control device 1.

[0031] After long-term use, the control device 1 ages due to structural aging, especially the main structure 4-1 of the display 4, which is flat and very easy to bend and deform downward, which not only affects the user's normal viewing of the information display, but also has the risk of damage if the deformation is serious. In this embodiment, the support structure 4-2 is supported by the internal structure of the control device 1, so that the main structure 4-1 has a better structural shape maintenance, avoids the bending deformation caused by aging, and prolongs the service life.

[0032] In addition, the support structure 4 - 2 can also play a role in positioning the installation height when assembling the display 4 . During installation, the support structure 4 - 2 can be supported on the internal structure of the control device 1 , and then the position can be adjusted circumferentially for installation.

[0033] In this embodiment, multiple support structures 4-2 are provided and distributed circumferentially on the bottom surface of the main structure 4-1, so that the support effect on the main structure 4-1 remains balanced, which can improve the overall structural stability of the main structure 4-1 and further enable it to have good structural shape maintenance.

[0034] In this embodiment, a circuit board 52 is disposed inside the control device, and the circuit board 52 is disposed horizontally. The circuit board 52 is responsible for receiving, processing and amplifying information from the sensor that senses the control action, and then the circuit board 52 transmits the information to the display 4 for display. The end of the support structure 4-2 extending into the control device is supported on the circuit board 52. Since the end of the support structure 4-2 is supported on the circuit board 52, it plays a role in limiting the circuit board 52, preventing the circuit board 52 from vibrating or shaking, so as to ensure the stability of its working state.

[0035] In this embodiment, a protective layer made of flexible material is provided at the end of the support structure 4-2, and specifically, foam and other materials can be used to prevent the support structure 4-2 from scratching or crushing the circuit board 52 during the installation process and subsequent use, thereby protecting the circuit board 52.

[0036] In addition, since the circuit board 52 is provided with a plurality of electronic components, such as capacitors, resistors, integrated circuits, etc., these electronic components are usually soldered to the circuit board 52 for the functions and connections of the electronic equipment, and these electronic components are usually arranged in the middle area of ​​the circuit board 52 and formed by the surface protrusions of the circuit board 52. Based on this, in this embodiment, the support structure 4-2 is a sheet-like structure, and its extension direction is suitable for avoiding these electronic components on the circuit board 52. The support structure 4-2 can be arranged to extend in the circumferential direction so that the support structure 4-2 does not extend into the middle area.

[0037] In this embodiment, the display 4 includes a display 4 bracket 41, an Oled module 42, and a lens 43, wherein the display 4 bracket 41 is mounted on the top of the control device 1, and the Oled module 42 is mounted on the top of the display 4. In this embodiment, the Oled module 42 is used to display information. The Oled module 42 is a display technology composed of organic light-emitting diodes, which has the following advantages and characteristics: the Oled module 42 can achieve a very high contrast ratio because it can completely turn off the pixels when displaying black, thereby producing a true black, rather than relying on the backlight to produce dark colors like an LCD screen. In particular, when the user uses the control device 1 in a kitchen environment, the clarity of the user's field of vision may be disturbed by factors such as oil smoke. In addition, the pixels of the Oled module 42 can respond very quickly, so smoother dynamic images and videos can be achieved, and compared with the LCD screen, the Oled module 42 can provide better visual effects at various angles without the problem of color shift or brightness reduction. These advantages and characteristics are very suitable for the performance requirements of the control device 1 for the display 4. The lens 43 is attached to the top of the display 4 bracket 41. The lens 43 is usually made of optical glass or plastic material that has been specially designed and coated. This type of lens 43 can effectively increase the contrast and clarity of the Oled module 42, and optimize the display effect by controlling the transmission and reflection of light. A commonly used type of lens 43 is an anti-reflection film or AR lens, which can reduce surface reflection and increase light transmittance, helping to reduce the impact of ambient light on the display effect, thereby increasing contrast and clarity. Another commonly used lens 43 is an optical enhancement film, which can improve the display effect through optical refraction and scattering, and increase color saturation and clarity.

[0038] In order to facilitate the use of the user, the size of the control device 1 of this embodiment is relatively small. Due to the limitation of the outer diameter of the control device 1, the size of the Oled module 42 is generally small, which will result in a small display area. Based on this, in this embodiment, the top surface of the lens 43 is a spherical surface, which is suitable for magnifying the information displayed by the Oled module 42, allowing the user to clearly see the information displayed by the Oled module 42. In addition, since the top surface of the lens 43 is set as a spherical surface, the user can also see the information displayed by the Oled module 42 under the perspective of squint, which expands the user's observation field of view and improves the user's use experience.

[0039] In this embodiment, the top surface of the display 4 bracket 41 has a mounting groove 41a formed by an inward depression, and the Oled module 42 is embedded in the mounting groove 41a. The depth of the mounting groove 41a makes the Oled module 42 substantially flush with the top surface of the display 4 bracket 41. A layer of adhesive layer 412 is provided on the rest of the top surface of the display 4 bracket 41. The adhesive layer 412 can specifically use a transparent double-sided adhesive tape. The bottom surface of the lens 43 and the top surface of the display 4 bracket 41 are adhered together by the adhesive layer 412, so that the lens 43 is attached to the top surface of the display 4 bracket 41.

[0040] In this embodiment, the display 4 bracket 41 and the top of the control device 1 are detachably connected. More specifically, a plurality of hollow column structures 11b are provided at the inner wall of the top of the control device 1. A fastener 11c is provided in the column structure 11b. The fastener 11c penetrates the display 4 bracket 41 and connects the display 4 bracket 41 and the top of the control device 1 together. The fastener 11c can be a fastening screw, which is threadedly connected in the column structure 11b. One end of the fastening screw with a nut penetrates and tightens the display 4 bracket 41, thereby realizing a detachable connection between the two. In addition, a blind hole 41b is provided at the top surface of the display 4 bracket 41 corresponding to the fastener 11c, so that the fastener 11c will not be exposed from the top surface of the display 4 bracket 41, thereby causing the lens 43 to be unable to be flatly fitted.

[0041] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
