[0048] This application provides a cooking utensil.

[0049] like Figure 1 As shown, in a specific embodiment, the cooking appliance 100 may be a rice cooker. The cooking appliance 100 may include a pot body 30 and a lid 10. Typically, the pot body 30 is used to heat the inner pot 31, which is a cooking container for holding food. The internal space of the inner pot 31 is a cooking cavity 33. The pot body 30 may have a cylindrical (or other shaped) receiving cavity, and the inner pot 31 can be freely placed into or removed from the receiving cavity to facilitate cleaning of the inner pot 31. The inner pot 31 is made of metal and is constructed as a rotating body with an opening and an inner cavity formed by the pot wall. The lid 10 is pivotally connected to the pot body 30 via a pivot axis to cover the pot body 30 and the inner pot 31.

[0050] like Figures 1 to 5 As shown, the lid 10 includes a panel 21, which provides the lower surface of the lid 10. That is, when the lid 10 covers the pot body 30, the lid 10 and the inner pot 31 enclose a cooking space, and the panel 21 forms the top plate of this cooking space. A pot opening sealing ring 22 is connected to the panel 21. When the lid 10 covers the pot body 30, the pot opening sealing ring 22 contacts the pot opening 32 of the inner pot 31 to relatively seal the cooking space. For example, the pot opening sealing ring 22 contacts the flange 35 at the pot opening 32.

[0051] For example, the lid 10 includes a faceplate assembly 11 and a removable lid assembly 20, which is detachably connected to the faceplate assembly 11. The faceplate assembly 11 is pivotally connected to the pot body 30 via a torsion spring 19. The faceplate assembly 11 also includes a lid body 12 that provides the outer shell of the lid 10. The removable lid assembly 20 includes a panel 21 and a pot rim sealing ring 22.

[0052] Panel 21 has a first region A1 corresponding to the pot opening 32, that is Figure 3 and Figure 5The area enclosed by the first blue virtual line 41. When the lid 10 closes the pot body 30, the projection of the edge of the pot opening 32 (i.e., the inner periphery of the flange 35) onto the panel 21 in the vertical projection of the cooking appliance 100 is the first virtual line 41. That is, the area of ​​the panel 21 enclosed by the first virtual line 41 (i.e., the first area A1) is the effective top plate of the cooking space. The first virtual line 41 is, for example, circular. It can be understood that the area S1 of the first area A1 is the same as or approximately the same as the cross-sectional area of ​​the pot opening 32.

[0053] During cooking, the steam in the cooking chamber 33 needs to be released. The panel 21 is provided with a steam vent 25 for releasing the cooking steam. The steam vent 25 is connected, for example, to a steam valve in the cover 10. Understandably, the steam vent 25 is located in the first region A1.

[0054] The cooking appliance 100 also includes a steam generator 34. The steam generator 34 is used to generate steam. For example, during the rice warming stage, the steam generator 34 operates, generating steam and introducing it into the cooking cavity 33 to keep the rice moist. The steam generator 34 is, for example, located in the pot body 30. Since the steam generator 34 requires water, the pot body 30 is generally not frequently stirred, which prevents water from spilling from the steam generator 34. To introduce the steam generated by the steam generator 34 into the cooking cavity 33, a steam channel 18 is provided in the lid 10 for communication with the steam generator 34. When the lid 10 closes the pot body 30, one end of the steam channel 18 is connected to the steam generator 34 (the steam outlet of the steam generator 34 is, for example, located on the upper surface of the pot body 30), and the other end is connected to the cooking cavity 33.

[0055] For example, such as Figure 3 As shown, a steam passage 18 is disposed in the lid assembly 11. The two ends of the steam passage 18 are a second opening 16 and a third opening 17, respectively. A removable lid assembly 20 is provided with a first opening 27 and a steam inlet 26. After the removable lid assembly 20 is installed onto the lid assembly 11, the first opening 27 engages with the third opening 17, and the steam inlet 26 engages with the second opening 16. When the lid 10 covers the pot body 30, the first opening 27 engages with the steam outlet of the steam generator 34, so that steam from the steam generator 34 enters the steam passage 18 through the first opening 27 and is released into the cooking cavity 33 through the steam inlet 26. The steam inlet 26 can also be understood as a port of the steam passage. The steam inlet 26 is used to communicate with the steam generator 34. It is understood that the steam inlet 26 is located in the first region A1.

[0056] The steam inlet 26 and the steam outlet 25 are not connected inside the cover 10. Optionally, a structure similar to a one-way valve is provided at the steam inlet 26, preventing airflow from entering the steam channel 18 from the steam inlet 26, but allowing airflow from the steam channel 18 to the steam inlet 26. Therefore, when releasing cooking steam, the steam in the cooking chamber 33 will not enter the steam channel 18, nor will it further enter the steam generator 34. Since cooking steam often contains foam when the food is fully boiled, preventing cooking steam from entering the steam channel 18 helps maintain the cleanliness of the steam channel 18 and the steam generator 34. When keeping rice moist, the moisturizing steam will not enter the steam exhaust passage from the cover 10, but will be completely introduced into the cooking chamber 33. Thus, the steam exhaust and moisturizing functions do not affect each other.

[0057] To reduce condensation on panel 21, such as Figures 2 to 4 As shown, a top heating assembly 50 is provided in the cover 10. The top heating assembly 50 is located above the panel 21. The top heating assembly 50 includes a top heating element 13 for realizing the heating function. When the top heating element 13 is powered on, it generates heat to raise the temperature of the panel 21, thereby reducing condensation on the panel 21.

[0058] The top heating assembly 50 includes a heating surface 51, which is the surface of the top heating assembly 50 facing the panel 21. When the top heating element 13 heats up, the heating surface 51 heats up, thereby heating the panel 21. The top heating element 13 is configured, for example, as a heating wire.

[0059] Preferably, such as Figure 5 As shown, in the projection of the cooking appliance 100 along a direction perpendicular to the panel 21, the heating surface 51 is located in the first region A1, and the steam inlet 26 and the steam outlet 25 are located on the same side of the top heating component 50 or the heating surface 51. The area of ​​the first region A1 is S1, and the area of ​​the heating surface 51 is S2 (i.e., the area of ​​the second region A2), where S2 / S1 ≥ 3 / 4. Thus, the top heating component 13 occupies as large an area as possible, so that the area of ​​the panel 21 that receives cooking steam (i.e., the first region A1) is heated as much as possible, reducing the condensation on the panel 21.

[0060] Here, the fact that the steam inlet 26 and the steam outlet 25 are located on the same side of the top heating element 50 or the heating surface 51 means that, in the projection of the cooking appliance 100 along the direction perpendicular to the panel 21, with the geometric center of the top heating element 50 or the heating surface 51 as the center, the maximum difference between the circumferential angle of the edge of the steam inlet 26 relative to the center and the circumferential angle of the edge of the steam outlet 25 relative to the center is less than 180 degrees.

[0061] Optionally, S2 / S1 ≤ 5 / 6. Thus, panel 21 provides sufficient area for steam inlet 26 and exhaust outlet 25 to ensure ventilation function.

[0062] To accommodate the circular shape of the pot opening 32, the heating surface 51 is also based on a circular design. For example, as Figures 3 to 5 As shown, the heating surface 51 is constructed in a circular shape with a notch, at which the steam inlet 26 and the steam outlet 25 are located. In the example shown, the notch is roughly triangular. Of course, the notch can also be roughly square, elliptical, etc.

[0063] Specifically, such as Figure 4 As shown, the top heating assembly 50 includes a top heating element 13 and an insulation plate 14. The top heating element 13 is disposed on the upper surface of the insulation plate 14. The insulation plate 14 is located above the panel 21. The surface of the insulation plate 14 facing the panel 21 is the heating surface 51. Preferably, at least a first region A1 of the heating surface 51 and the panel 21 is constructed as a flat plate. The heating surface 51 and the first region A1 of the panel 21 are arranged parallel to each other.

[0064] The lid assembly 11 includes a lid body 12, a top heating element 50, and a heat insulation ring 15. The lid body 12 is connected to the pot body 30 via a torsion spring 19. A panel 21 is disposed on the lower side of the lid body 12. The axial direction of the heat insulation ring 15 is vertical. The upper side of the heat insulation ring 15 is connected to the lid body 12, and the lower side of the heat insulation ring 15 is connected to the insulation plate 14. The top heating element 13 is located substantially on the inner circumference of the heat insulation ring 15.

[0065] For example, the insulation plate 14 is provided with a first connecting portion 14A, which engages with a second connecting portion 15A on the lower surface of the heat insulation ring 15. A third connecting portion (not shown) on the upper surface of the heat insulation ring 15 is connected (by snap-fit ​​or screw-fastened) to a fourth connecting portion 12B on the lower surface of the cover body 12. The heating wire of the top heating element 13 is fixed to the upper surface of the insulation plate 14, for example, with adhesive. The insulation plate 14 is made of a metal material (e.g., aluminum) and can be quickly heated by the top heating element 13. Thus, the insulation plate 14 forms part of the lower surface of the cover assembly 11, which is sufficiently close to the panel 21, facilitating the heating of the panel 21. For example, when the removable cover assembly 20 is installed to the cover assembly 11, the distance between the insulation plate and the panel is 0 to 2 mm, for example, 0 to 1.5 mm. The heat insulation ring 15 is sandwiched between the insulation plate 14 and the cover body 12. The heat insulation ring 15 is made of a high-temperature resistant (e.g., 200°C) material (e.g., high-temperature resistant plastic), so that the heat of the insulation board 14 is difficult to transfer to the cover body 12, thus preventing the cover body 12 from being affected by high temperature.

[0066] Optionally, the outer edge of the top heating element 13 defines a closed second virtual envelope 42. Figure 4 and Figure 5(The red dashed line in the image). Here, the second region A2 enclosed by the second virtual envelope 42 is roughly the area covered (or occupied) by the top heating element 13. The second virtual envelope 42 is defined by the outer edge of the top heating element 13. For example, considering the top heating element 13 as a whole, when the top heating element 13 has a continuous outer edge, the second virtual envelope 42 coincides with the continuous outer edge; when the top heating element 13 has a discontinuous outer edge, the envelope (or fitted curve) formed by the discontinuous points on the outer edge can be used as the second virtual envelope 42. The shape of the edge contour (second region A2) of the insulation board 14 is similar to the second envelope 42 formed by the outer contour of the top heating element 13. Since the coverage area of ​​the top heating element 13 is limited, the insulation board 14 is concentrated in the coverage area of ​​the top heating element 13, which saves material on the insulation board 14. In other words, after determining the shape of the insulation board 14, the top heating element 13 is made to cover the insulation board 14 as much as possible.

[0067] Understandably, both the steam inlet 26 and the steam outlet 25 are connected to a steam passage, which is not suitable for placement in the area covered by the top heating element 13. Therefore, the steam inlet 26 and the steam outlet 25 are located outside the second area A2.

[0068] In order to allow the top heating element 13 to have a larger coverage area, the steam inlet 26 and the steam outlet 25 are placed as close to each other as possible to occupy the smallest possible area.

[0069] For example, the outer edges of the steam inlet 26 and the outer edges of the exhaust outlet 25 define a closed third virtual envelope 43. Figure 5 (The green dashed line in the diagram). Here, the steam inlet 26 and the exhaust outlet 25 are considered as a whole, and the area enclosed by the third virtual envelope 43 is roughly the area covered (or occupied) by this whole. The outer side of the steam inlet 26 and the outer side of the exhaust outlet 25 refers to the side that is away from each other (opposite to the side that is opposite to each other), that is, the outer side of the whole formed by the two. The third virtual envelope 43 is defined by the outer edge of the whole of the steam inlet 26 and the exhaust outlet 25. The method for determining the third virtual envelope 43 is similar to that of the second virtual envelope 42. When the outer edge is continuous, the third virtual envelope 43 coincides with the continuous outer edge; when the outer edge is discontinuous, the envelope (or fitted curve) formed by the discontinuous points on the outer edge can be used as the third virtual envelope 43.

[0070] Optionally, the maximum distance between two points on the third virtual envelope 43 is less than or equal to 20% of the diameter of the pot opening 32 (e.g., the diameter of the circle of the first virtual line 41). Alternatively, the maximum distance between a point on the edge of the steam inlet 26 and a point on the edge of the steam outlet 25 is less than or equal to 20% of the diameter of the pot opening 32. Thus, the steam inlet 26 and the steam outlet 25 are as small as possible and close to each other, allowing the top heating element 13 to have a larger coverage area.

[0071] Optionally, the minimum distance between the third virtual envelope 43 and the edge of the first region A1 (the first virtual line 41) is 0 to 5 mm. Alternatively, the minimum distance between the edge of the steam inlet 26 and the first virtual line 41 is 0 to 5 mm (e.g., 0-2 mm), and the minimum distance between the edge of the exhaust port 25 and the first virtual line 41 is 0 to 5 mm. Thus, by positioning the steam inlet 26 and the exhaust port 25 close to the edge of the first region A1, the overall integrity of the coverage area of ​​the top heating element 13 is improved, making the placement of the top heating element 13 easier (the top heating element 13 does not interfere with the steam passage).

[0072] Optionally, in the projection of the cooking appliance 100 along a direction perpendicular to the panel 21, the minimum distance between the third virtual envelope 43 and the second virtual envelope 42 is 0 to 25 mm, for example, 0 to 20 mm, 0 to 15 mm, or 10 to 20 mm. Alternatively, in the projection of the cooking appliance 100 along a direction perpendicular to the panel 21, the minimum distance between the edge of the steam inlet 26 and the edge of the heating surface 51 is 0 to 25 mm, and the minimum distance between the edge of the steam outlet 25 and the edge of the heating surface 51 is 0 to 25 mm. Thus, the top heating element 13 can maximize its coverage area.

[0073] To make the steam inlet 26 and the exhaust port 25 as close to each other as possible, Figure 5 As shown, optionally, one of the steam inlet 26 and the steam outlet 25 surrounds the outer periphery of the other. For example, one of the steam inlet 26 and the steam outlet 25 may be constructed as a circular hole, and the other as an arc-shaped hole, with the arc-shaped hole surrounding the outer periphery of the circular hole and concentric with the circular hole (center). In the illustrated embodiment, panel 21 is provided with one steam outlet 25 and multiple steam inlets 26. The steam outlet 25 is constructed as a circular hole, and the steam inlets 26 are constructed as arc-shaped holes. Multiple steam inlets 26 surround the outer periphery of the steam outlet 25. The multiple steam inlets 26 are located on the same annulus, which is concentric with the circle of the steam outlet 25.

[0074] exist Figure 5 In the embodiment shown, the third virtual envelope 43 can be the circle containing the outer edge of the steam inlet 26.

[0075] In this application, the cover 10 can also be constructed as a non-removable structure, that is, the cover 10 does not have a removable cover, and the panel 21 is the lower panel of the cover 10.
