[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0029] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0030] like Figure 1 and Figure 2As shown, the cooking appliance of this embodiment includes a display assembly and a heating device, and the display assembly includes a light board 10 and a display panel 20. The light board 10 includes a substrate 11, a sensor disposed on the substrate 11, and an indicator light 13 indicating the state of the sensor. The sensor includes a spring 12, a first end of the spring 12 is connected to the substrate 11, and the indicator light 13 is disposed outside the spring 12. The display panel 20 is disposed outside the light board 10, and the indicator light 13 can be transmitted from the display panel 20 when it is lit.

[0031] By applying the technical solution of this embodiment, the display component interacts with the user through the sensor and the indicator light 13. The sensor is a touch sensor, specifically including a spring 12, which is electrically connected to the substrate 11. When the user's finger or other part approaches or touches the position of the display panel 20 corresponding to the spring 12, the electric field on the spring 12 changes, and then a signal is given to the corresponding indicator light 13, and the indicator light 13 lights up. Since the indicator light 13 is set on the outside of the spring 12, it can avoid the range covered by the user's finger, so that the light can be smoothly emitted from the display panel 20, and then recognized by the user's eyes, so that the user can quickly and accurately know the working status of the cooking appliance.

[0032] Furthermore, if Figure 3 As shown, in the cooking utensil of this embodiment, the display panel 20 includes a panel body 21 and a rib 22, the first end of the rib 22 is connected to the panel body 21, the second end of the rib 22 extends toward the substrate 11, the rib 22 is arranged corresponding to the spring 12 and is sleeved outside the spring 12, and the second end of the spring 12 is in contact with the inner side of the panel body 21.

[0033] Since the spring is made of flexible material, it is easy to tilt and deform when the force is uneven. In the actual assembly process, due to the limitation or obstruction of other structures, other structures may touch the edge of the spring when approaching the spring, thereby causing the spring to tilt and move away from the predetermined area on the display panel after assembly. In this way, when the user touches the predetermined area on the display panel, the spring cannot receive the signal in time and accurately, and the cooking appliance cannot respond accordingly.

[0034] The rib 22 of the present application can be sleeved outside the spring 12 to form a support on the outer periphery of the spring 12. When the spring 12 is subjected to a force in the radial direction, the outer periphery of the spring 12 can be pressed against the inner surface of the rib 22, so that the spring 12 remains relatively upright and in the area corresponding to the display panel 20, thereby ensuring the sensitivity of the spring 12 and avoiding accidental touches.

[0035] Preferably, the ribs 22 of this embodiment are cylindrical, and the cylindrical ribs 22 have a complete structure and are evenly stressed.

[0036] In other embodiments not shown in the figure, the ribs can also be inserted into the spring. Accordingly, when the spring is subjected to radial force, the inner circumference of the spring can abut against the outer surface of the ribs to keep the spring relatively upright, which can also ensure the sensitivity of the spring and avoid accidental touch.

[0037] Furthermore, if Figure 3 and Figure 4 As shown, in this embodiment, a guide conical surface 23 is provided on the inner side of the second end of the rib 22. The guide conical surface 23 can be used as an end chamfer of the rib 22 to reduce burrs generated at the second end of the rib 22 during processing and keep the surface of the rib 22 smooth; it can also play a guiding role to guide the spring 12 into the rib 22 to prevent the second end of the rib 22 from pressing the spring 12 and causing the spring 12 to be skewed.

[0038] Corresponding to the embodiment in which the rib is inserted into the spring, the guide cone surface can be selectively set on the outer side of the second end of the rib, so that the rib extends into the spring with a smaller cross-section, which can also play a guiding role, so that the spring is sleeved on the rib along the outer surface of the rib, thereby realizing the role of the rib supporting the spring.

[0039] A light-transmitting area is provided on the display panel. When the light below the display panel is on, light is transmitted through the light-transmitting area to prompt the user of the status of the cooking appliance. Specifically, the panel itself is provided with a non-light-transmitting area and a light-transmitting area. The light-transmitting area is formed by providing a light-shielding structure on the transparent panel. The light-shielding structure may be a light-shielding cover. The light-transmitting area is formed by hollowing out the light-shielding structure.

[0040] Furthermore, if Figure 3 and Figure 4 As shown, a light-transmitting hole 24 is provided on the panel body 21 of the cooking appliance of this embodiment at a position corresponding to the indicator light 13, and the light-transmitting hole 24 forms a light-transmitting area. The light-transmitting hole 24 reduces the loss of light when it is emitted from the display panel 20, improves the display effect of the display component of this embodiment, and further improves the user experience.

[0041] Preferably, if Figure 4 As shown, the light-transmitting hole 24 of this embodiment is arranged adjacent to the rib 22. The above structure shortens the distance between the indicator light 13 and the spring 12, making the structure of the lamp board 10 compact.

[0042] For the display assembly of this embodiment, the indicator light 13 is arranged outside the spring 12, and the light-transmitting hole 24 is arranged at the position corresponding to the indicator light 13. The distance between the light-transmitting hole 24 and the spring 12 is small. When the user touches the position of the display panel 20 corresponding to the spring 12, some fingers may be inserted into or close to the light-transmitting hole 24. However, the distinction between strong and weak electricity on the light board 10 is not thorough. From the perspective of safety in use, it should be considered that the spring 12 is strong electricity. When the above situation occurs, if Figure 3As shown, the rib 22 is sleeved on the outer periphery of the spring 12 and blocked between the light-transmitting hole 24 and the spring 12. On the one hand, an insulating layer is formed between the spring 12 and the user's finger, thereby increasing the resistance between the user's finger and the spring 12 and reducing the risk of strong electricity directly breaking through the air and causing electric shock to the user; on the other hand, the creepage distance between the spring 12 and the light-transmitting hole 24 is increased, further reducing the risk of electric shock to the user.

[0043] Preferably, if Figure 4 As shown, the length L of the rib 22 of this embodiment is ≥ 8 mm. The above structure makes the creepage distance from the spring 12 to the light-transmitting hole 24 along the surface of the rib 22 at least 8 mm, ensuring the safety of the cooking utensil of this embodiment.

[0044] Specifically, the position planned on the display panel for interacting with the user is a button, wherein the first button 26 controls only two states, "on" and "off", and the corresponding indicator light 13 indicates the corresponding state of the first button 26 by "lighting up" and "extinguishing". The main purpose of this embodiment is to make the light-transmitting area avoid the area covered by the user's finger under normal conditions, so according to the size of the range of the first button 26, the light-transmitting hole 24 can be within the range of the first button 26 or outside the range of the first button 26.

[0045] More specifically, the first button 26 includes a regular pressing area, which is a range that the user will most likely touch when seeing the range shown on the first button 26. The size of the regular pressing area is generally smaller than or equal to the size of the first button 26. When the size of the regular pressing area is smaller than the size of the first button 26, the light-transmitting hole 24 is entirely or partially located outside the regular pressing area. At this time, the light-transmitting hole 24 may be inside the first button 26 or outside the first button 26. When the size of the regular pressing area is equal to the size of the first button 26, the light-transmitting hole 24 is at least partially located outside the first button 26 to ensure that the light-transmitting hole 24 can clearly display the "lit" state.

[0046] Preferably, the area of ​​the touch area sensed by the sensing member is larger than the area of ​​the first button 26. Further, in this embodiment, there are multiple sensing members, and there are also multiple indicator lights 13. The sensing members and the indicator lights 13 are arranged one-to-one, and the first button 26 on the display panel 20 is also arranged one-to-one with the sensing members. Further, the light board 10 also includes multiple display lights 14 for displaying cooking time or cooking status, and the display panel 20 also includes a second button 27 for controlling the multiple display lights 14. When the user touches the second button 27 multiple times, the display lights 14 light up alternately and indicate the corresponding cooking time or cooking status.

[0047] Specifically, the cooking appliance of this embodiment is an electric pressure cooker, which includes a pot body and a pot cover arranged on the pot body, and the operation panel is arranged on the pot cover. According to factors such as the size and structure of the operation panel, the technical solution of the operation panel of this embodiment can also be applied to the pot body of the electric pressure cooker. Specifically, the carrier of the operation panel is not limited to the electric pressure cooker, and is also applicable to cooking appliances such as electric rice cookers and electric fryers.

[0048] like Figures 5 to 7 The schematic diagram of the structure of the display assembly of the cooking utensil of the second embodiment is shown. Similar to the structure of the first embodiment, the light-transmitting hole 24 in the display assembly of the second embodiment is flat and roughly rectangular, and is arranged at the position of the panel body 21 corresponding to the indicator light 13. Specifically, the length of the light-transmitting hole 24 is close to the diameter of the indicator light 13, and the width is smaller than the diameter of the indicator light 13. A button is arranged at the position corresponding to the sensing element below the light-transmitting hole 24. The sensing element is also a touch sensing element, specifically including a spring 12. When the user's finger approaches or touches the button, the electric field on the spring 12 changes, thereby realizing the function of controlling the cooking utensil.

[0049] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0050] The display component interacts with the user through the sensor and indicator light. The sensor is a touch sensor, specifically including a spring, which is electrically connected to the substrate. When the user's finger or other part approaches or touches the position of the display panel corresponding to the spring, the electric field on the spring changes, and then sends a signal to the corresponding indicator light, and the indicator light lights up. Since the indicator light is set on the outside of the spring, it can avoid the range covered by the user's finger, so that the light can be smoothly emitted from the display panel and then recognized by the user's eyes, so that the user can quickly and accurately know the working status of the cooking appliance.

[0051] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0052] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0053] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
