[0040] 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.

[0041] like Figure 1 and Figure 6 As shown, the cooking utensil of this embodiment includes a pot body, a pot cover 10, a pressure-cooking pressure-limiting assembly 20, and a pressure-free cooking exhaust member 30. The pot body is used to hold the food to be cooked. The pot cover 10 is arranged on the pot body, and the pot cover 10 has a mounting through hole 11. The pressure-cooking pressure-limiting assembly 20 includes a mounting structure and a pressure-limiting valve 21, the mounting structure has an exhaust passage arranged through, and the pressure-limiting valve 21 is arranged at the exhaust passage. The pressure-free cooking exhaust member 30 has an exhaust hole 31 arranged through. When the cooking utensil is working, one of the pressure-cooking pressure-limiting assembly 20 and the pressure-free cooking exhaust member 30 is selected to be arranged at the mounting through hole 11 and the mounting through hole 11 is blocked.

[0042] By applying the technical solution of this embodiment, when the pressure-cooking pressure-limiting assembly 20 is installed at the installation through hole 11, the pressure-limiting valve can generate pressure in the pot body, thereby performing pressure cooking. When the pressure-free cooking exhaust member 30 is installed at the installation through hole 11, the steam generated during cooking is discharged to the outside through the exhaust hole 31, thereby performing pressure-free cooking. The above structure achieves the effect of both pressure cooking and pressure-free cooking on the same cooking utensil. Therefore, the technical solution of this embodiment solves the problem of poor cooking flexibility of the electric pressure cooker in the prior art.

[0043] like Figure 1 and Figure 6 As shown, in the technical solution of this embodiment, when the pressure-cooking pressure-limiting assembly 20 is arranged at the mounting through hole 11, the mounting structure is connected with the pot cover 10 by snapping, and when the pressure-free cooking exhaust member 30 is arranged at the mounting through hole 11, the pressure-free cooking exhaust member 30 is connected with the pot cover 10 by snapping. Specifically, the snapping connection enables the user to remove the pressure-cooking pressure-limiting assembly 20 or the pressure-free cooking exhaust member 30 by hand, so that the user can replace the pressure-cooking pressure-limiting assembly 20 or the pressure-free cooking exhaust member 30. In an embodiment not shown, the pressure-cooking pressure-limiting assembly 20 or the pressure-free cooking exhaust member 30 and the pot cover 10 can also be connected by other means, such as screw connection.

[0044] like Figure 2 , Figure 3 as well as Figure 7As shown, in the technical solution of this embodiment, a plurality of elastic clamping members 41 are arranged on the pot cover 10, and each elastic clamping member 41 has a clamping protrusion 411 protruding in the radial direction of the pot cover 10. The mounting structure includes a mounting plate 22, and a first clamping groove 42 is arranged on the side of the mounting plate 22 away from the mounting through hole 11. The pressure-free cooking exhaust member 30 is an exhaust cover, and a second clamping groove 43 is arranged on the side of the exhaust cover away from the mounting through hole 11. When the pressure-free cooking pressure limiting assembly 20 is arranged at the mounting through hole 11, the first clamping protrusion 411 is clamped into the first clamping groove 42, and when the pressure-free cooking exhaust member 30 is arranged at the mounting through hole 11, the clamping protrusion 411 is clamped into the second clamping groove 43. Specifically, the elastic clamping member 41 is an elastic arm made of metal, and the above-mentioned clamping protrusion 411 is formed after the elastic arm is bent. Further, the clamping protrusion 411 is formed in the following manner: the lower end of the elastic clamping member 41 is connected to the pot cover 10, the elastic clamping member 41 first extends toward the bottom of the pot cover 10, and then the elastic clamping member 41 extends toward the horizontal direction and forms a horizontal section, wherein the horizontal section extends in the direction of the mounting through hole 11. The horizontal section forms the above-mentioned clamping protrusion 411. An accommodating space is formed between the horizontal section and the bottom wall of the pot cover 10. When the pressure-cooking pressure-limiting assembly 20 is arranged at the mounting through hole 11, the edge of the mounting plate 22 is clamped in the accommodating space, and the horizontal section is clamped into the first clamping groove 42. When the pressure-cooking pressure-limiting assembly 20 is arranged at the mounting through hole 11, the edge of the exhaust cover is clamped in the accommodating space, and the horizontal section is clamped into the second clamping groove 43.

[0045] like Figure 2 As shown, in the technical solution of this embodiment, a plurality of elastic clamping members 41 are evenly distributed along the circumferential direction of the mounting through hole 11. Specifically, there are three elastic clamping members 41 in this embodiment.

[0046] like Figure 4 and Figure 5 As shown, in the technical solution of this embodiment, when the pressure-cooking pressure-limiting assembly 20 is arranged at the mounting through hole 11, the pressure-cooking pressure-limiting assembly 20 is installed from the inner side of the pot cover 10, and the cooking appliance further includes a first sealing ring 51 arranged between the mounting structure and the inner side of the pot cover 10. The first sealing ring 51 can seal the gap between the pressure-cooking pressure-limiting assembly 20 and the lower surface of the pot cover 10, thereby ensuring that steam does not leak out along the gap between the pressure-cooking pressure-limiting assembly 20 and the lower surface of the pot cover 10.

[0047] like Figure 4 and Figure 5As shown, in the technical solution of this embodiment, the mounting plate 22 is located on the inner side of the pot cover 10, and a first groove 221 is provided on the side of the mounting plate 22 facing the pot cover 10, and the first sealing ring 51 is accommodated in the first groove 221. Specifically, the first groove 221 is an annular groove, and the first sealing ring 51 is an annular sealing ring. Further, the diameter of the mounting plate 22 is greater than the diameter of the mounting through hole 11.

[0048] like Figure 3 and Figure 5 As shown, in the technical solution of this embodiment, a portion of the mounting plate 22 is bent in a direction away from the pot cover 10 to form a first groove 221 on the side of the mounting plate 22 facing the pot cover 10. The pot cover 10 is provided with a plurality of elastic clamping members 41, each of which has a clamping protrusion 411 protruding in the radial direction of the pot cover 10, and a first clamping groove 42 is provided on the side of the mounting plate 22 away from the mounting through hole 11, and the first clamping groove 42 is located on the bent portion of the mounting plate 22, and the clamping protrusion 411 is clamped into the first clamping groove 42.

[0049] like Figure 8 and Fig. 9 As shown, in the technical solution of this embodiment, when the pressureless cooking exhaust member 30 is arranged at the installation through hole 11, the pressureless cooking exhaust member 30 is installed from the inner side of the pot cover 10, and the cooking appliance further includes a second sealing ring 52 arranged between the pressureless cooking exhaust member 30 and the inner side surface of the pot cover 10. The second sealing ring 52 can seal the gap between the pressureless cooking exhaust member 30 and the lower surface of the pot cover 10, thereby ensuring that steam does not leak out along the gap between the pressureless cooking exhaust member 30 and the lower surface of the pot cover 10.

[0050] like Figure 8 As shown, in the technical solution of this embodiment, the pressureless cooking exhaust member 30 is an exhaust cover, and a second groove 32 is provided on the side of the exhaust cover facing the pot cover 10, and the second sealing ring 52 is accommodated in the second groove 32. Specifically, the second groove 32 is an annular groove, and the second sealing ring 52 is an annular sealing ring. Further, the diameter of the exhaust cover is greater than the diameter of the mounting through hole 11.

[0051] like Figure 7 and Fig. 9 As shown, in the technical solution of the present embodiment, the exhaust cover portion is bent in a direction away from the pot cover 10 to form a second groove 32 on the side of the exhaust cover facing the pot cover 10, and a plurality of elastic clips 41 are provided on the pot cover 10, each elastic clip 41 has a clip protrusion 411 protruding along the radial direction of the pot cover 10, and a second clip groove 43 is provided on the side of the exhaust cover away from the mounting through hole 11, and the second clip groove 43 is located on the bent portion of the exhaust cover, and the clip protrusion 411 is clipped into the second clip groove 43.

[0052] like Figure 1 and Figure 6 As shown, in the technical solution of this embodiment, the pot cover 10 includes an upper cover 12 and an inner cover 13, and the mounting through hole 11 is arranged on the inner cover 13. Specifically, the upper cover 12 includes an inner lining and a surface cover, and the inner cover 13 is arranged on the lower side of the inner lining.

[0053] like Figure 5 As shown, in the technical solution of this embodiment, the mounting structure includes a mounting plate 22 and an exhaust pipe 23 arranged on the mounting plate 22 , an exhaust channel is formed inside the exhaust pipe 23 , and the pressure limiting valve 21 is sleeved on the exhaust pipe 23 .

[0054] like Figures 10 to 12 As shown, the cooking appliance further includes a detection device, a display panel 60 and a light source module. The detection device is used to detect whether the pressure-limiting component 20 for pressure cooking is installed on the pot cover 10 or the pressure-free cooking exhaust component 30 is installed on the pot cover 10. 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 illumination of light of different wavelengths. The light source module is used to illuminate the display panel 60, the light source module is arranged in the pot cover 10, and the light source module can emit light of different wavelengths. When the detection device detects that the pressure-limiting component 20 for pressure cooking is installed on the pot cover 10, 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, and when the detection device detects that the pressure-free cooking exhaust component 30 is installed on the pot cover 10, 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.

[0055] By applying the technical solution of this embodiment, when the detection device detects that the pressure-limiting assembly 20 for pressure cooking is installed on the pot cover 10, the light source module emits light of a wavelength corresponding to the first display pattern 61, thereby lighting up the first display pattern 61. When the detection device detects that the pressure-free cooking exhaust member 30 is installed on the pot cover 10, the light source module emits light of a wavelength corresponding to the second display pattern 62, thereby lighting up the second display pattern 62. 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.

[0056] 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.

[0057] It should be noted that from Fig.10 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.

[0058] The detection device is a magnetic induction structure, and a magnetic part is provided on the pressure-cooking pressure-limiting component 20 or the pressure-free cooking exhaust component 30. Specifically, the magnetic induction structure can detect a magnetic field. For example, the magnetic part is provided on the pressure-cooking pressure-limiting component 20. When the pressure-cooking pressure-limiting component 20 is installed on the pot cover 10, the magnetic part is close to the magnetic induction structure, so that the magnetic induction structure detects the magnetic field of the magnetic part. When the pressure-free cooking exhaust component 30 is installed on the pot cover 10, the magnetic induction structure cannot detect the magnetic field. Therefore, the magnetic induction structure can determine whether the pressure-cooking pressure-limiting component 20 or the pressure-free cooking exhaust component 30 is installed on the pot cover 10 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 an abutment boss is correspondingly provided on the pressure-cooking pressure-limiting component 20 or the pressure-free cooking exhaust component 30.

[0059] Preferably, the magnetic induction structure is a Hall sensor or a reed switch.

[0060] Preferably, the detection device is arranged in the upper cover 12. Specifically, the upper cover 12 includes an inner lining and a surface cover, and the detection device is arranged in the inner lining.

[0061] like Fig.11As shown, in the technical solution of this embodiment, the first display pattern 61 includes a "Pressure" option. Specifically, when the pressure cooking pressure limiting assembly 20 is installed on the pot cover 10, the pressure option is lit, thereby prompting the user that the pressure cooking inner pot cover is installed at this time.

[0062] like Fig.12 As shown, in the technical solution of this embodiment, the second display pattern 62 includes a "no pressure" option. Specifically, when the pressureless cooking exhaust member 30 is installed on the pot cover 10, the pressure option is lit, thereby prompting the user that the pressureless cooking inner pot cover is installed at this time.

[0063] like Fig.10 As shown, in the technical solution of this embodiment, the first display pattern 61 and the second display pattern 62 are arranged in an overlapping manner. Specifically, the first display pattern 61 and the second display pattern 62 are both located at the upper left corner of the display panel 60. When the pressure-cooking pressure limiting assembly 20 is installed on the pot cover 10, the first display pattern 61 is lit. When the pressure-free cooking exhaust member 30 is installed on the pot cover 10, the second display pattern 62 is lit.

[0064] It should be noted that, combined with Fig.11 and Fig.12 It can be seen that when the cooking appliance is pressure-free cooking, some display patterns on the display panel 60 are not displayed. Specifically, some options in pressure cooking are not displayed, such as pressure selection options, pressure cooking ingredients, etc.

[0065] 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 pressure-limiting component 20 for pressure cooking is installed on the pot cover 10, the first LED lamp emits light so that the first display pattern 61 is displayed, and when the pressure-free cooking exhaust member 30 is installed on the pot cover 10, the second LED lamp emits light so that the second display pattern 62 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 61 and the second display pattern 62 are misaligned, the first LED lamp and the first display pattern 61 are correspondingly arranged. The second LED lamp and the second display pattern 62 are correspondingly arranged.

[0066] 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.

[0067] Preferably, the cooking utensil in this embodiment is an electric pressure cooker.
