DETAILED DESCRIPTION

[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 shown, the cooking utensil of this embodiment includes a pot body 10, a pot cover 20, a detection device, a display panel 40 and a light source module. Among them, the pot body 10 is used to hold the cooked food. The pot cover 20 is arranged on the pot body 10, and the pot cover 20 includes a pot cover body 21 and an inner pot cover detachably arranged below the pot cover body 21. The inner pot cover includes a first inner pot cover 22 and a second inner pot cover 23, and the first inner pot cover 22 or the second inner pot cover 23 is installed on the pot cover body 21. The detection device is used to detect the type of the inner pot cover installed on the pot cover body 21. The display panel 40 is provided with a first display pattern 41 and a second display pattern 42, the first display pattern 41 and the second display pattern 42 are overlapped or partially overlapped or arranged adjacently, and the first display pattern 41 and the second display pattern 42 are displayed under the irradiation of light of different wavelengths. The light source module is used to illuminate the display panel 40, and the light source module is arranged in the pot cover 20, and the light source module can emit light of different wavelengths. Further, when the detection device detects that the first inner pot cover 22 is installed on the pot cover body 21, the light source module emits light of a wavelength corresponding to the first display pattern 41 so that the first display pattern 41 is displayed; when the detection device detects that the second inner pot cover 23 is installed on the pot cover body 21, the light source module emits light of a wavelength corresponding to the second display pattern 42 so that the second display pattern 42 is displayed.

[0035] By applying the technical solution of this embodiment, when the detection device detects that the first inner pot cover 22 is installed on the pot cover body 21, the light source module emits light of a wavelength corresponding to the first display pattern 41, thereby lighting up the first display pattern 41. When the detection device detects that the second inner pot cover 23 is installed on the pot cover body 21, the light source module emits light of a wavelength corresponding to the second display pattern 42, thereby lighting up the second display pattern 42. The above structure can realize the display of two display patterns at the same position, thereby making the volume occupied by the display panel smaller. Therefore, the technical solution of this embodiment solves the problem that the display panel of the electric pressure cooker in the prior art occupies a large space.

[0036] Preferably, the first display pattern 41 and the second display pattern 42 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 excite 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 41 and the second display pattern 42 include display words and / or display patterns.

[0037] It should be noted that from Figure 1 It can be seen that the first display pattern 41 and the second display pattern 42 are arranged in an overlapping manner. In an embodiment not shown, the first display pattern 41 and the second display pattern 42 may also be arranged to partially overlap. Alternatively, the first display pattern 41 and the second display pattern 42 may also be arranged in a staggered manner. In the case of a staggered arrangement, since one of the first display pattern 41 and the second display pattern 42 is illuminated when the cooking appliance is working, the distance between the first display pattern 41 and the second display pattern 42 can be set to be smaller, and the space occupied can also be reduced relative to the display panel in the prior art.

[0038] like Figures 4 to 6 As shown, in the technical solution of this embodiment, the first inner pot cover 22 is a pressure cooking inner pot cover. Specifically, when the pressure cooking inner pot cover is installed on the pot cover body 21, during the cooking process of the cooking utensil, pressure will be generated in the pot body 10 and positioned at a pressure level, thereby achieving pressure cooking.

[0039] like Figure 6As shown, in the technical solution of this embodiment, the first inner pot cover 22 includes a first inner pot cover body 221, a first exhaust structure 222 arranged on the first inner pot cover body 221, and a pressure limiting valve 223 arranged on the first exhaust structure 222. Specifically, both ends of the first exhaust structure 222 are respectively connected to the first inner pot cover body 221. When the cooking appliance is working, pressure is generated in the pot body 10. When the pressure is lower than the preset pressure, the steam cannot push open the pressure limiting valve 223, thereby maintaining the pressure in the pot body 10. When the pressure is higher than the preset pressure, the steam pushes open the pressure limiting valve 223 and exhausts the gas.

[0040] like Figure 6 As shown, in the technical solution of this embodiment, the first exhaust structure 222 is an exhaust pipe. The pressure limiting valve 223 is sleeved on the exhaust pipe.

[0041] like Figures 7 and 8 As shown, in the technical solution of this embodiment, the second inner pot cover 23 is a pressureless cooking inner pot cover. Specifically, when the pressureless cooking inner pot cover is installed on the pot cover body 21, no pressure or only very small pressure is generated in the pot body 10 when the cooking utensil is working, thereby realizing pressureless cooking.

[0042] like Figure 7 and Figure 8 As shown, in the technical solution of this embodiment, the second inner pot cover 23 includes a second inner pot cover body 231 and a second exhaust structure 232 arranged on the second inner pot cover body 231. Specifically, both ends of the second exhaust structure 232 are connected to the second inner pot cover body 231. When the cooking appliance is working, the steam in the pot body 10 is directly discharged to the outside through the second exhaust structure 232.

[0043] like Figure 7 As shown, in the technical solution of this embodiment, the second exhaust structure 232 is an exhaust hole. The exhaust hole has a good exhaust effect, thereby ensuring that no pressure is generated in the pot body 10. Of course, the second exhaust structure 232 can also be an exhaust pipe.

[0044] like Figure 6As shown, in the technical solution of this embodiment, the detection device is a magnetic induction structure, and a magnetic member 50 is provided on the first inner pot cover 22 or the second inner pot cover 23. Specifically, the magnetic induction structure can detect a magnetic field. In this embodiment, the magnetic member 50 is provided on the first inner pot cover 22. When the first inner pot cover 22 is installed on the pot cover body 21, the magnetic member 50 is close to the magnetic induction structure, so that the magnetic induction structure detects the magnetic field of the magnetic member 50. When the second inner pot cover 23 is installed on the pot cover body 21, the magnetic induction structure cannot detect the magnetic field. Therefore, the magnetic induction structure can determine the type of the inner pot cover by whether it can detect the magnetic field. Of course, the detection device can also be other structures, for example, the detection device can be a contact switch, and abutment bosses are correspondingly provided on the first inner pot cover 22 or the second inner pot cover 23.

[0045] Preferably, the magnetic induction structure is a Hall sensor or a reed switch.

[0046] Preferably, the detection device is arranged in the pot cover body 21. Specifically, the pot cover body includes an inner lining and a surface cover, and the detection device is arranged in the inner lining.

[0047] like Figure 2 As shown, in the technical solution of this embodiment, the first display pattern 41 includes a "pressurized" option. Specifically, when the pressurized inner pot cover is installed on the pot cover body 21, the pressurized option is lit, thereby prompting the user that the pressurized cooking inner pot cover is installed at this time.

[0048] like Figure 2 As shown, in the technical solution of this embodiment, the second display pattern 42 includes a "no pressure" option. Specifically, when the pressureless inner pot cover is installed on the pot cover body 21, the pressure option is lit, thereby prompting the user that the pressureless cooking inner pot cover is installed at this time.

[0049] like Figure 1 As shown, in the technical solution of this embodiment, the first display pattern 41 and the second display pattern 42 are superimposed. Specifically, the first display pattern 41 and the second display pattern 42 are both located at the upper left corner of the display panel 40. When the first inner pot cover 22 is installed on the pot cover body 21, the first display pattern 41 is lit. When the second inner pot cover 23 is installed on the pot cover body 21, the second display pattern 42 is lit.

[0050] It should be noted that, combined with Figure 1 and Figure 2 It can be seen that when the cooking appliance is pressure-free cooking, some display patterns on the display panel 40 are not displayed. Specifically, some options in pressure cooking are not displayed, such as pressure selection options, pressure cooking ingredients, etc.

[0051] In the technical solution of this embodiment, the light source module includes a first LED lamp and a second LED lamp of different colors, wherein when the detection device detects that the first inner pot cover 22 is installed on the pot cover body 21, the first LED lamp emits light so that the first display pattern 41 is displayed, and when the detection device detects that the second inner pot cover 23 is installed on the pot cover body 21, the second LED lamp emits light so that the second display pattern 42 is displayed. Specifically, the first LED lamp is a red lamp, and the second LED lamp is a green lamp. When the first display pattern 41 and the second display pattern 42 are misaligned, the first LED lamp and the first display pattern 41 are correspondingly arranged. The second LED lamp and the second display pattern 42 are correspondingly arranged.

[0052] It should be noted that, in an embodiment not shown, the light source of the light source module may also be a lamp structure that can emit light of different colors.

[0053] Preferably, the cooking utensil in this embodiment is an electric pressure cooker.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.
