[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of 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 application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] 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.

[0034] like Figures 1 to 3 ,as well as Fig.11As shown, the cooking utensil of this embodiment includes a pot body 10, a pot cover 20, a pressure limiting valve 40, a driving structure 50, a display panel 60 and a light source module. Among them, the pot body 10 is used to hold the food to be cooked. The pot cover 20 is arranged on the pot body 10, and the pot cover 20 is provided with an exhaust channel 30. The pressure limiting valve 40 includes a pressure limiting valve body 41 and a counterweight 42 arranged on the pressure limiting valve body 41. The driving structure 50 cooperates with the counterweight 42, and the driving structure 50 can drive the counterweight 42 to separate from the pressure limiting valve body 41. The display panel 60 is provided with a first display pattern 61 and a second display pattern 62, the first display pattern 61 and the second display pattern 62 are overlapped or partially overlapped or arranged adjacently, and the first display pattern 61 and the second display pattern 62 are displayed under the irradiation of light of different wavelengths respectively. The light source module is used to illuminate the display panel 60, and the light source module is arranged in the pot cover 20, and the light source module can emit light of different wavelengths. Furthermore, when the counterweight 42 and the pressure-limiting valve body 41 act together on the exhaust channel 30, the light source module emits light of a wavelength corresponding to the first display pattern 61, so that the first display pattern 61 is displayed. When the driving structure 50 drives the counterweight 42 to separate from the pressure-limiting valve body 41, the light source module emits light of a wavelength corresponding to the second display pattern 62, so that the second display pattern 62 is displayed.

[0035] By applying the technical solution of this embodiment, when the counterweight 42 and the pressure limiting valve body 41 act together on the exhaust passage 30, the light source module emits light of a wavelength corresponding to the first display pattern 61, so that the first display pattern 61 is displayed. When the driving structure 50 drives the counterweight 42 to separate from the pressure limiting valve body 41, the light source module emits light of a wavelength corresponding to the second display pattern 62, so that the second display pattern 62 is displayed. The above structure enables different display patterns to be displayed at the same position or adjacent positions on the display panel 60, thereby making the area occupied by the display panel smaller. Therefore, the technical solution of this embodiment solves the problem that the display panel of the cooking appliance in the prior art occupies a large area.

[0036] It should be noted that the above-mentioned detachment of the counterweight 42 from the pressure-limiting valve body 41 means that the gravity of the counterweight 42 does not act on the pressure-limiting valve body 41, that is, the gravity of the pressure-limiting valve body 41 only acts on the exhaust passage 30. In the case where the counterweight 42 is detached from the pressure-limiting valve body 41, the counterweight 42 may be connected to the pressure-limiting valve body 41 through the connection structure, but the gravity of the counterweight 42 does not act on the pressure-limiting valve body 41.

[0037] Preferably, the first display pattern 61 and the second display pattern 62 are formed by processing a photosensitive medium material, a filter medium material, or a chromophore material. For a photosensitive medium, the corresponding light irradiated onto the medium can stimulate the medium to develop color to display a pattern. For a filter medium, due to the different wavelengths of light, through the principle of filtering, two or more optical materials are used at the same position, and the wavelengths of the light sources are different, so that different contents are displayed in color; for a chromophore material, the optical material is a coating material containing different chromophores, and this material is combined with a transparent material to allow only light of a specific wavelength to pass through and display color. Optionally, the first display pattern 61 and the second display pattern 62 include display words and / or display patterns.

[0038] It should be noted that from Figure 1 It can be seen that the first display pattern 61 and the second display pattern 62 are arranged in an overlapping manner. In an embodiment not shown, the first display pattern 61 and the second display pattern 62 may also be arranged to partially overlap. Alternatively, the first display pattern 61 and the second display pattern 62 may also be arranged in a staggered manner. In the case of a staggered arrangement, since one of the first display pattern 61 and the second display pattern 62 is illuminated when the cooking appliance is working, the distance between the first display pattern 61 and the second display pattern 62 can be set to be smaller, and the space occupied can also be reduced relative to the display panel in the prior art.

[0039] like Figures 4 to 6 As shown, in the technical solution of this embodiment, a metal part 421 is provided on the counterweight 42, and the driving structure 50 includes a magnetic part 51, and the magnetic part 51 attracts the metal part 421 to make the counterweight 42 separate from the pressure limiting valve body 41. Specifically, when the distance between the magnetic part 51 and the metal part 421 is close enough, the magnetic part 51 attracts the metal part 421 to make the counterweight 42 rise. At this time, the pressure limiting valve body 41 no longer supports the counterweight 42, that is, the pressure limiting valve body 41 acts alone on the exhaust channel 30. At this time, the light source module emits light with a wavelength corresponding to the second display pattern 62, so that the second display pattern 62 is displayed. When the distance between the magnetic part 51 and the metal part 421 is far, the magnetic force applied by the magnetic part 51 to the metal part 421 is not enough to attract the metal part 421, and at this time, the counterweight 42 and the pressure limiting valve body 41 act together on the exhaust channel 30. At this time, the light source module emits light with a wavelength corresponding to the first display pattern 61, so that the first display pattern 61 is displayed.

[0040] like Figures 4 to 9As shown, in the technical solution of this embodiment, the driving structure 50 also includes a swing rod 52, and the swing rod 52 is swingably disposed in the pot cover 20, and the magnetic component 51 is disposed on the swing rod 52. When the swing rod 52 swings, the magnetic component 51 can be aligned or misaligned with the metal component 421. When the magnetic component 51 is misaligned with the metal component 421, the counterweight 42 and the pressure-limiting valve body 41 act together on the exhaust channel 30. When the magnetic component 51 is aligned with the metal component 421, the magnetic component 51 attracts the metal component 421 to separate the counterweight 42 from the pressure-limiting valve body 41. Specifically, when the swing rod 52 swings, the swing rod 52 can drive the magnetic component 51 to move together. Figures 4 to 6 It can be seen that when the swing rod 52 swings to the right end, the magnetic member 51 and the metal member 421 are aligned vertically, and the magnetic member 51 attracts the metal member 421 to make the counterweight 42 rise. Figures 7 to 9 It can be seen that when the swing rod 52 swings to the left end, the magnetic component 51 and the metal component 421 are misaligned in the horizontal direction. At this time, the magnetic force exerted by the magnetic component 51 on the metal component 421 is not sufficient to attract the metal component 421.

[0041] like Figure 4 and Figure 7 As shown, in the technical solution of this embodiment, the driving structure 50 also includes a driving motor 53, the first end of the swing rod 52 is connected to the motor shaft of the driving motor 53, and the magnetic member 51 is arranged at the second end of the swing rod 52. Specifically, when the motor shaft of the driving motor 53 rotates, the swing rod 52 is driven to rotate together. Preferably, the driving motor 53 can be a stepping motor, thereby ensuring the control accuracy.

[0042] like Figure 4 Shown and Figure 7 As shown, in the technical solution of this embodiment, the cooking appliance further includes a detection structure 70 and a control device, the detection structure 70 detects the position of the swing rod 52, the control device is connected to the detection structure 70 and the light source module, and the control device controls the wavelength of the light emitted by the light source module according to the detection result of the detection structure 70. Specifically, by detecting the position of the swing rod 52, the relative position between the magnetic part 51 and the metal part 421 can be determined, and then it can be determined whether the counterweight block 42 is sucked up, and finally it can be determined whether the pressure limiting valve body 41 acts on the exhaust passage 30 alone, or the counterweight block 42 and the pressure limiting valve body 41 act on the exhaust passage 30 together. When the detection structure 70 determines that the counterweight block 42 and the pressure limiting valve body 41 act on the exhaust passage 30 together, the control device controls the light source module to emit light with a wavelength corresponding to the first display pattern 61, so that the first display pattern 61 is displayed. When the detection structure 70 determines that the pressure limiting valve body 41 acts on the exhaust passage 30 alone, the control device controls the light source module to emit light with a wavelength corresponding to the second display pattern 62, so that the second display pattern 62 is displayed.

[0043] like Figure 4and Figure 7 As shown, in the technical solution of this embodiment, the detection structure 70 is a magnetic induction structure, and the magnetic induction structure detects the magnetic induction intensity of the magnetic member 51. Specifically, Figure 4 and Figure 7 It can be seen that the magnetic induction structure is arranged on the left side of the swing rod 52. Figure 4 When the swing rod 52 swings to the middle position, the magnetic induction structure detects that the magnetic field strength of the magnetic member 51 is small. Figure 7 When the position of the pendulum 52 is in the middle, the magnetic induction structure detects that the magnetic field strength of the magnetic member 51 is relatively large. Therefore, the magnetic induction structure can determine the position of the pendulum 52 by determining the magnetic field strength of the magnetic member 51.

[0044] Preferably, the magnetic induction structure is a reed switch or a Hall sensor.

[0045] like Fig.10 As shown, in the technical solution of this embodiment, the first display pattern 61 includes a first operation option 611, and the first operation option 611 includes one or more of "soup", "stew", "nutritional steaming" and "waterless baking". Specifically, when the counterweight 42 and the pressure limiting valve body 41 act together on the exhaust channel 30, the pressure applied by the pressure limiting valve 40 to the exhaust channel 30 is relatively large, and at this time the cooking appliance is suitable for the above-mentioned cooking operation.

[0046] like Fig.11 As shown, in the technical solution of this embodiment, the second display pattern 62 includes a second operation option 621, and the second operation option 621 includes one or more of "cooking rice", "cooking porridge", "quickly cooking rice" and "grain porridge". Specifically, when the counterweight 42 is separated from the pressure-limiting valve body 41, that is, when the pressure-limiting valve body 41 acts on the exhaust passage 30, the pressure applied by the pressure-limiting valve 40 to the exhaust passage 30 is small, and the cooking appliance is suitable for the above-mentioned cooking operation.

[0047] Furthermore, the first operation option 611 and the second operation option 621 are printed in different colors. At the same time, the "soup making" option and the "rice cooking" option are overlapped, the "stew stewing" option and the "porridge cooking" option are overlapped, the "nutritional steaming" option and the "quick rice cooking" option are overlapped, and the "waterless baking" option and the "grain porridge" option are overlapped.

[0048] In the technical solution of this embodiment, the light source module includes a first LED lamp and a second LED lamp, the color of the first LED lamp is the same as the color of the first display pattern 61, and the color of the second LED lamp is the same as the color of the second display pattern 62. When the counterweight 42 and the pressure-limiting valve body 41 act together on the exhaust passage 30, the first LED lamp emits light, and when the driving structure 50 drives the counterweight 42 to separate from the pressure-limiting valve body 41, the second LED lamp emits light. Specifically, in an embodiment not shown, the light source module can also select a light source structure that can emit different wavelengths, that is, different colors.

[0049] like Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, in the technical solution of this embodiment, the pot cover 20 includes an inner lining 21, a surface cover 22 arranged on the inner lining 21, and an inner pot cover 23 arranged below the inner lining 21, the exhaust channel 30 and the pressure limiting valve 40 are arranged on the inner pot cover 23, and the driving structure 50 is arranged on the inner lining 21.

[0050] Preferably, the cooking utensil in this embodiment is an electric pressure cooker.

[0051] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the present application. 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 those of ordinary skill in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered 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 that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0052] In the description of the present application, it should be understood 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, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0053] 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.

[0054] 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. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
