[0033] As shown in FIGS. 1 and 2, the lid assembly for a cooking appliance according to the embodiment of the present invention can be applied to cooking appliances such as pressure cookers, cooking machines, and electric rice cookers.

[0034] In conventional cooking appliances, the heating device is often integrated into the lid to heat food three-dimensionally, evenly heat the top of the food, sufficiently stimulate the Maillard reaction, and make the food more flavorful. Among these, a coil is provided on the top lid, and the food is heated by the magnetic force generated when an electric current flows through the coil, thereby providing the cooking appliance with sufficient heat power and achieving a better cooking effect on the food.

[0035] In conventional technology, when a coil is installed inside the lid of a cooking appliance, the steam valve of the rice cooker must be attached externally, which not only makes the structure of the entire lid complex and increases its volume, but also reduces the effectiveness of the steam valve, affecting the cooking effect of the cooking appliance.

[0036] Therefore, in the embodiment of the present application, the steam valve 2 and the lid assembly 100 with the heating coil winding 32 are installed simultaneously inside. The installation of the coil winding 32 allows the top of the food to be heated evenly, heating the food in a three-dimensional manner, fully stimulating the Maillard reaction, making the food more flavorful, and providing the cooking appliance with sufficient heat power, resulting in a better cooking effect on the food. Furthermore, since the steam valve 2 is built-in, the function and effect of the steam valve 2 are better, the integration of the lid assembly 100 is higher, and the overall volume of the cooking appliance can be installed in a smaller volume.

[0037] Hereinafter, a lid assembly 100 for a cooking appliance according to an embodiment of the present invention will be described with reference to FIGS.

[0038] The lid assembly 100 of the cooking appliance according to the embodiment of the present application may include an inner lid 1, a steam valve 2 and a coil assembly 3.

[0039] A first mounting space 11 is provided in the inner lid 1, and the first mounting space 11 can be used to install the coil assembly 3; at least a portion of the steam valve 2 is extended into the inner lid 1; that is, the steam valve 2 and the coil assembly 3 are arranged in the same horizontal plane; the steam valve 2 and the coil assembly 3 can be simultaneously and integrally installed inside the lid assembly 100; and the steam valve 2 is installed in parallel with the coil assembly 3, so that the two do not interfere with each other.

[0040] Furthermore, the coil assembly 3 includes a coil holder 31 and a coil winding 32, and when electricity is applied to the coil winding 32, food can be heated. The coil holder 31 is fixed to the inner lid 1 and is located in the first mounting space 11, and the coil winding 32 is provided in the coil holder 31. The coil holder 31 can support and fix the coil winding 32, so that the coil winding 32 can be stably provided in the first mounting space 11, and the stability of the overall structure and winding shape of the coil winding 32 can be ensured. The coil winding 32 can stably form a magnetic field to heat food.

[0041] Since at least a portion of the steam valve 2 extends into the inner lid 1 and the center of the coil assembly 3 is not located at the same position as the center of the inner lid 1, when the coil winding 32 is wound in a circle, the heating center of the coil is not located at the center, which is limited by the area of ​​the first mounting space 11, and the area of ​​the coil winding 32 that can be installed in the first mounting space 11 is reduced.

[0042] In order for the coil assembly 3 to heat food better, the coil winding 32 is wound non-circularly, which not only allows the heat generated from the coil to be more concentrated in the center position, maximizing the temperature in the center and improving the cooking effect of the food there, but also allows the coil winding 32 to fully utilize the space in the first mounting space 11, allowing the coil winding 32 to have a larger layout area, and more heat is generated after the coil winding 32 is energized, which fully stimulates the Maillard reaction and improves the cooking effect of the cooking appliance.

[0043] Referring to FIG. 2, because the coil winding 32 is wound in an oval shape, the heat generated by the coil winding 32 is concentrated at the center, maximizing the temperature at the center and improving the cooking effect of the food there. In addition, the coil winding 32 can also fully utilize the space within the first mounting space 11, so that more heat is generated after the coil winding 32 is energized, which fully stimulates the Maillard reaction and improves the cooking effect of the cooking appliance.

[0044] As described above, the steam valve 2 and the coil winding 32 are simultaneously provided inside the cover assembly 100, which results in a higher degree of integration, a compact overall structure, and no interference between the steam valve 2 and the coil winding 32.

[0045] The cooking appliance lid assembly 100 according to the embodiment of the present application has a higher degree of integration because the steam valve 2 of the cooking appliance lid assembly 100 is built-in, and the coil winding 32 can heat food efficiently, sufficiently stimulating the Maillard reaction, and improving the cooking effect of the cooking appliance.

[0046] In some embodiments, the temperature sensor 5 needs to be located in the center of the inner lid 1, so the central portion of the elliptical coil winding 32 can provide sufficient space for the placement of the temperature sensor 5.

[0047] As shown in Figure 2, the extension direction of the pivot axis of the inner cover 1 is the direction shown by AB in Figure 2, and the inner cover 1 has a first direction (the direction shown by CD in Figure 2) perpendicular to the extension direction of the pivot axis. At least a part of the steam valve 2 is extended into the inner cover 1 and is located on one side of the inner cover 1 in the first direction. As a result, the length of the first mounting space 11 in the extension direction of the pivot axis is longer than the width of the first mounting space 11 in the first direction, and therefore the length of the coil winding 32 in the extension direction along the pivot axis is greater than the width along the first direction. The shape of the coil winding 32 is adapted to the shape of the first mounting space 11, which allows the heat generated from the coil to be more concentrated in the central position, maximizing the temperature at the center and improving the cooking effect of the food there. In addition, the coil winding 32 can also make full use of the space in the first mounting space 11. More heat is generated after the coil winding 32 is energized, which fully stimulates the Maillard reaction and improves the cooking effect of the cooking appliance.

[0048] 1 and 5, the coil winding 32 includes an upper layer winding 321 and a lower layer winding 322, and the upper layer winding 321 is located above the lower layer winding 322. By winding the upper and lower layers of windings, the coil assembly 3 has better electromagnetic matching parameters and achieves a better electromagnetic heating effect.

[0049] Referring to FIG. 1, the number of turns of the upper winding 321 is different from the number of turns of the lower winding 322, so that the upper winding 321 and the lower winding 322 form an electromagnetic field with higher energy, thereby improving the heating effect.

[0050] In some embodiments, the steam valve 2 is located outside the first mounting space 11 and is arranged close to the coil assembly 3, which not only makes the overall structure of the cover assembly 100 compact and reduces the overall volume of the cover assembly 100, but also allows the coil assembly 3 to be arranged large to ensure heating effect.

[0051] According to some embodiments of the present application, the central axis of the coil winding 32 does not overlap with the center of the lid assembly 100. In some embodiments, the inner pot (not shown) is circular in shape, which ensures a uniform heating effect of the cooking appliance. Referring to Figures 2 and 3, both the steam valve 2 and the coil assembly 3 are located above the inner pot, i.e., first mounting spaces 11 for mounting the steam valve 2 and the coil assembly 3 are both located in the portion of the inner lid 1 corresponding to the inner pot. The steam valve 2 is located outside the first mounting space 11 of the inner lid 1 and extends into the inner lid 1, so that the steam valve 2 occupies a portion of the circular portion of the inner lid 1 corresponding to the inner pot. In order to enlarge the first mounting space 11, the first mounting space 11 is located in the portion of the inner lid 1 corresponding to the inner pot other than the position of the steam valve 2, so that the shape of the first mounting space 11 is formed as a large divided circle.

[0052] As a result, the first mounting space 11 includes a first inner wall 111 and a second inner wall 112, the first inner wall 111 being arc-shaped and the second inner wall 112 being flat. The second inner wall 112 is connected to both ends of the first inner wall 111 and is installed close to the steam valve 2, thereby increasing the installation area of ​​the first mounting space 11 and further increasing the layout area of ​​the coil winding 32 of the coil assembly 3 within the first mounting space 11. This allows more heat to be generated after the coil winding 32 is energized, which fully stimulates the Maillard reaction and improves the cooking effect of the cooking appliance.

[0053] Furthermore, the outer peripheral wall of the coil holder 31 is installed in the same shape as the first mounting space 11, and the coil holder 31 can be installed in close contact with the outer peripheral wall of the first mounting space 11, which improves the installation stability of the coil holder 31 and allows the coil holder 31 to be arranged within the entire first mounting space 11. Furthermore, the arrangement area of ​​the coil winding 32 within the first mounting space 11 can be increased, which generates more heat after the coil winding 32 is energized, fully stimulating the Maillard reaction and improving the cooking effect of the cooking appliance.

[0054] As shown in FIG. 5, the coil holder 31 includes an upper holder 311 and a lower holder 312, which are fixed relative to each other to define a storage space 313 for the coil winding 32. The coil winding 32 is disposed within the storage space 313 defined by the upper holder 311 and the lower holder 312. The upper holder 311 and the lower holder 312 are used to support and fix the coil winding 32, allowing the coil winding 32 to be stably installed within the first mounting space 11. This also ensures the stability of the overall structure and winding shape of the coil winding 32, allowing the coil winding 32 to stably form a magnetic field to achieve heating.

[0055] Referring to FIG. 5, the upper holder 311 and / or the lower holder 312 are provided with radiation avoidance spaces 314 spaced apart corresponding to the coil windings 32. When the coil windings 32 are energized, a magnetic field is generated, and magnetic induction can pass through the lower radiation avoidance spaces 314 and be heated, thereby ensuring the heating effect of the coil windings 32.

[0056] As shown in FIG. 5 , the upper holder 311 and / or the lower holder 312 are provided with a plurality of radiating ribs 315, which stably fix and support the coil winding 32 and prevent the shape and structure of the coil winding 32 from being damaged. Adjacent radiating ribs 315 define radiation avoidance spaces 314, which not only allow radiation to be better transmitted downward but also provide a certain heat dissipation effect.

[0057] As shown in Figures 2 and 5, in the radial direction toward the center of the inner lid 1, the width of the outer end of the radial rib 315 is larger than the width of the inner end, which reinforces the structural strength of the upper layer holder 311 and the lower layer holder 312 while further improving the heat dissipation effect of the upper layer holder 311 and the lower layer holder 312.

[0058] According to some embodiments of the present application, the difference between the maximum and minimum widths of the radial ribs 315 ranges from 4.5 mm to 20 mm, which reinforces the structural strength of the upper holder 311 and the lower holder 312 while further improving the heat dissipation effect of the upper holder 311 and the lower holder 312.

[0059] As shown in FIG. 5 , annular convex ribs 316 are provided on the upper holder 311 and / or the lower holder 312. The annular convex ribs 316 can reinforce the structural strength of the upper holder 311 and / or the lower holder 312 and enable the coil windings 32 to be installed more stably. On the other hand, the coil windings 32 are fitted onto the convex ribs 316, and the shape of the coil windings 32 surrounded by the outer contour of the convex ribs 316 is controlled. Moreover, the installation of the convex ribs 316 allows the coil windings 32 to be distributed evenly and ensures the structural stability of the coil windings 32.

[0060] In some embodiments, the upper layer winding 321 and the lower layer winding 322 are simultaneously surrounded by the convex rib 316, so that the innermost winding diameters of the upper layer winding 321 and the lower layer winding 322 are the same, which allows the coil assembly 3 to have better electromagnetic matching parameters and achieve a better electromagnetic heating effect.

[0061] The heated lid 4 is removably attached to the inner lid 1 and is located below the coil assembly 3. When electricity is applied to the coil winding 32, the heated lid 4 is heated, and when electricity is applied to the coil winding 32, a magnetic field is formed, which heats the heated lid 4 within the magnetic field.

[0062] In some embodiments, a second mounting space is provided in the inner cover 1, and the second mounting space is located on one side of the first mounting space 11. The steam valve 2 is provided in the heating cover 4 and in the second mounting space, and extends into the inner cover 1 to discharge steam to the outside.

[0063] Referring to Figures 3 and 6, a groove 41 is provided on the upper surface of the heating lid 4, and the bottom of the groove 41 protrudes toward the inner pot so that steam generated during food cooking can collect at the bottom of the groove 41. The orthogonal projection of the coil winding 32 on the heating lid 4 covers the groove 41, allowing the heating lid 4 at the groove 41 to obtain sufficient heat, reducing condensation at the bottom of the groove 41 and preventing the condensation from dripping onto the food and affecting the texture of the food, thereby ensuring the cooking effect of the food.

[0064] As shown in FIG. 4, the cooking appliance lid assembly 100 further includes a glass partition plate 12, which is located in the first mounting space and below the coil assembly 3. The radiation generated from the coil winding 32 can be transmitted through the glass partition plate 12 to the heating plate, and the heat generated from the heating lid 4 is less likely to be transmitted to the coil assembly 3 through the glass, thereby improving the heat utilization rate.

[0065] As shown in Figures 1 and 3, the cooking appliance lid assembly 100 further includes a temperature sensor 5, which is fixed to the coil holder 31 and located in the inner ring space 33 of the coil winding 32, and the temperature sensor 5 is installed at the center position of the inner lid 1 so as to detect the temperature at the center position of the heating lid 4.

[0066] According to some embodiments of the present application, the temperature sensor 5 is installed offset from the center of the coil winding 32 to simultaneously detect the position temperature at the center of the heating lid 4 and the steam temperature, thereby making full use of the winding space of the coil holder 31.

[0067] Hereinafter, a lid assembly 100 for a cooking appliance according to another embodiment of the present invention will be described with reference to FIGS.

[0068] The lid assembly 100 of the cooking appliance according to the embodiment of the present application may include an inner lid 1, a steam valve 2, a coil assembly 3 and a heating lid 4.

[0069] A first mounting space 11 is provided in the inner cover 1, and the first mounting space 11 can be used to install the coil assembly 3. The steam valve 2 is provided in the inner cover 1 and is located on one side of the first mounting space 11. That is, the steam valve 2 and the coil assembly 3 are arranged in the same horizontal plane, and the steam valve 2 and the coil assembly 3 can be installed simultaneously and integrated inside the cover assembly 100. Moreover, the steam valve 2 is installed in parallel with the coil assembly 3, and the two do not interfere with each other.

[0070] As shown in Figures 1 and 3, the heating lid 4 is provided on the inner lid 1 and is located below the coil assembly 3. When the coil winding 32 is energized, the heating lid 4 is heated. Both the steam valve 2 and the coil assembly 3 are provided above the inner pot, i.e., both the first mounting space 11 for mounting the steam valve 2 and the coil assembly 3 are provided in the portion of the lid assembly 100 corresponding to the inner pot. In some embodiments, the shape of the projection of the inner pot on a horizontal plane is circular or approximately circular, and at least a portion of the steam valve 2 extends into the inner lid 1 and is provided above the inner pot, so that the steam valve 2 occupies a portion of the circular portion of the inner lid 1 corresponding to the inner pot. In order to position the first mounting space 11 large, the first mounting space 11 is positioned in the portion corresponding to the inner pot other than the corresponding position of the steam valve 2 on the inner lid 1. Therefore, the shape of the first mounting space 11 is formed as a large divided circle.

[0071] As a result, the first mounting space 11 includes a first inner wall 111 and a second inner wall 112, the first inner wall 111 being arc-shaped and the second inner wall 112 being flat. The second inner wall 112 is connected to both ends of the first inner wall 111 and is installed close to the steam valve 2, thereby increasing the installation area of ​​the first mounting space 11 and further increasing the layout area of ​​the coil winding 32 of the coil assembly 3 within the first mounting space 11. This allows more heat to be generated after the coil winding 32 is energized, which fully stimulates the Maillard reaction and improves the cooking effect of the cooking appliance.

[0072] Furthermore, the coil assembly 3 includes a coil holder 31 and a coil winding 32. When electricity is applied to the coil winding 32, a magnetic field is formed to heat the heating cover 4 within the magnetic field. The coil holder 31 is fixed to the inner cover 1 and is located in the first mounting space 11. The coil winding 32 is provided in the coil holder 31. The coil holder 31 can support and fix the coil winding 32. The coil winding 32 can be stably provided in the first mounting space 11, and the stability of the overall structure and winding shape of the coil winding 32 can be ensured. The coil winding 32 can stably form a magnetic field to heat the heating cover 4.

[0073] The outer wall of the coil holder 31 is installed in the same shape as the first mounting space 11, and the coil holder 31 can be installed in close contact with the outer wall of the first mounting space 11, which improves the installation stability of the coil holder 31 and allows the coil holder 31 to be arranged within the entire first mounting space 11. Furthermore, the arrangement area of ​​the coil winding 32 within the first mounting space 11 can be increased, which generates more heat after the coil winding 32 is energized, fully stimulating the Maillard reaction and improving the cooking effect of the cooking appliance.

[0074] As described above, the steam valve 2 and the coil winding 32 are installed simultaneously inside the cover assembly 100, resulting in a higher degree of integration and a compact overall structure. In addition, the steam valve 2 and the coil winding 32 do not interfere with each other. At the same time, the coil winding 32 is installed to avoid the steam valve 2, and by enlarging the first mounting space 11, the layout area of ​​the coil winding 32 within the first mounting space 11 can be increased. This allows more heat to be generated after the coil winding 32 is energized, fully stimulating the Maillard reaction and improving the cooking effect of the cooking appliance.

[0075] The cooking appliance lid assembly 100 according to the embodiment of the present application has a higher degree of integration because the steam valve 2 of the cooking appliance lid assembly 100 is built-in, and the coil winding 32 can heat food efficiently, sufficiently stimulating the Maillard reaction, and improving the cooking effect of the cooking appliance.

[0076] As shown in FIG. 5 , the coil holder 31 includes an upper holder 311 and a lower holder 312, which are fixed relative to each other to define a storage space 313 for the coil winding 32. The coil winding 32 is disposed in the storage space 313 defined by the upper holder 311 and the lower holder 312. The upper holder 311 and the lower holder 312 are used to support and fix the coil winding 32, so that the coil winding 32 can be stably installed in the first mounting space 11 and the stability of the overall structure and winding shape of the coil winding 32 can be ensured. The coil winding 32 stably forms a magnetic field to heat the heating cover 4.

[0077] Referring to FIG. 5, the upper holder 311 and / or the lower holder 312 are provided with radiation avoidance spaces 314 spaced apart to correspond to the coil windings 32. When the coil windings 32 are energized, a magnetic field is generated, and magnetic induction lines can pass through the lower radiation avoidance spaces 314 to heat the heating cover 4, thereby ensuring the heating effect of the coil windings 32.

[0078] As shown in FIG. 5, the upper holder 311 and / or the lower holder 312 are provided with a plurality of radiating ribs 315, which stably fix and support the coil winding 32 and prevent the shape and structure of the coil winding 32 from being damaged. Adjacent radiating ribs 315 define a radiation avoidance space 314, which not only allows radiation to be better transmitted downward to the heating cover 4 but also achieves better heat dissipation.

[0079] As shown in Figures 2 and 5, in the radial direction toward the center of the inner lid 1, the width of the outer end of the radial rib 315 is larger than the width of the inner end, which reinforces the structural strength of the upper layer holder 311 and the lower layer holder 312 while further improving the heat dissipation effect of the upper layer holder 311 and the lower layer holder 312.

[0080] According to some embodiments of the present application, the difference between the maximum and minimum widths of the radial ribs 315 ranges from 4.5 mm to 20 mm, which reinforces the structural strength of the upper holder 311 and the lower holder 312 while further improving the heat dissipation effect of the upper holder 311 and the lower holder 312.

[0081] As shown in FIG. 5 , annular convex ribs 316 are provided on the upper holder 311 and / or the lower holder 312. The annular convex ribs 316 can reinforce the structural strength of the upper holder 311 and / or the lower holder 312 and enable the coil windings 32 to be installed more stably. On the other hand, the coil windings 32 are fitted onto the convex ribs 316, and the shape of the coil windings 32 surrounded by the outer contour of the convex ribs 316 is controlled. Moreover, the installation of the convex ribs 316 allows the coil windings 32 to be distributed evenly and ensures the structural stability of the coil windings 32.

[0082] In some embodiments, the upper layer winding 321 and the lower layer winding 322 are simultaneously surrounded by the convex rib 316, so that the innermost winding diameters of the upper layer winding 321 and the lower layer winding 322 are the same, which allows the coil assembly 3 to have better electromagnetic matching parameters and achieve a better electromagnetic heating effect.

[0083] It should be noted that the embodiments and features of the embodiments of the present application can be combined with each other as long as they do not conflict.

[0084] Hereinafter, a specific embodiment of a lid assembly 100 for a cooking appliance will be described with reference to the drawings.

[0085] 1 and 3, the lid assembly 100 includes a panel (not shown), a magnetic barrier 6, a temperature regulator assembly 50, a coil assembly 3, an inner lid 1, and a movable lid plate assembly 40. The panel is located on top of the entire lid assembly 100 structure, allowing the user to control the operating state of the cooking appliance through the panel, and the magnetic barrier 6 is provided between the panel and the coil assembly 3 to block radiation from the coil assembly 3, preventing the panel from being heated by the coil assembly 3 and ensuring the stable operation of the electrical components integrated in the panel.

[0086] The movable cover plate assembly 40 is provided below the cover body assembly 100 and is disposed between the inner pot and the inner cover 1 of the cooking appliance. A heating cover 4 is provided on the movable cover plate assembly 40. The heating cover 4 is located below the coil assembly 3 provided on the inner cover 1. The heating cover 4 is heated by the coil assembly 3 to heat the ingredients in the inner pot. The heating cover 4 is provided with a protrusion structure and a groove 41 structure, which are used to increase the area that receives heat radiation, allowing the heating cover 4 to receive sufficient heat.

[0087] Referring to Figure 2, the inner lid 1 is square in shape, and the portion of the square inner lid 1 corresponding to the inner pot of the cooking appliance is circular. A steam valve 2 is provided on one side of the inner lid 1, and at least a portion of the steam valve 2 is located in the circular portion of the inner lid 1 corresponding to the inner pot of the cooking appliance.

[0088] The inner lid 1 is further provided with a first mounting space 11, the steam valve 2 is located on one side of the first mounting space 11, and the first mounting space 11 is also arranged in a circular portion of the inner lid 1 corresponding to the inner pot of the cooking appliance.

[0089] Since the steam valve 2 occupies a portion of the circular portion of the inner lid 1 corresponding to the inner pot, the shape of the first mounting space 11 is formed as the shape of a large divided circle, i.e., the circular portion of the inner lid 1 corresponding to the inner pot is divided into two parts by a single chord, with the steam valve 2 provided in the smaller divided circular part and the first mounting space 11 provided in the larger divided circular part.

[0090] As a result, the first mounting space 11 includes a first inner wall 111 and a second inner wall 112, the first inner wall 111 is formed as an arc, the second inner wall 112 is formed as a plane, the second inner wall 112 is connected to both ends of the first inner wall 111, and the second inner wall 112 is installed in close proximity to the steam valve 2.

[0091] The temperature regulator assembly 50, the coil assembly 3 and the glass partition plate 12 are arranged in the first mounting space 11. As shown in FIG. 5, the coil assembly 3 includes a coil holder 31 and a coil winding 32. The temperature regulator assembly 50 is fixed to the coil holder 31 and is located in the inner ring space 33 of the coil winding 32. The temperature regulator assembly 50 integrates a temperature control valve and a temperature sensor 5. The temperature sensor 5 is arranged at the center of the inner cover 1 and can detect the temperature at the center of the heating cover 4.

[0092] The outer wall of the coil holder 31 is installed in the same shape as the first mounting space 11, and the coil holder 31 can be installed in close contact with the outer wall of the first mounting space 11, which improves the installation stability of the coil holder 31 and allows the coil holder 31 to be arranged within the entire first mounting space 11. Furthermore, the arrangement area of ​​the coil winding 32 within the first mounting space 11 can be increased, which generates more heat after the coil winding 32 is energized, fully stimulating the Maillard reaction and improving the cooking effect of the cooking appliance.

[0093] The coil winding 32 is wound in a hollow oval shape, with its width greater than its height, like an eye, with a smooth central section perpendicular to the extension direction of the pivot axis and sharp ends along the extension direction of the pivot axis. This shape ensures that the central section of the coil winding 32 has sufficient space for the temperature controller assembly 50 to be placed in. The coil winding 32 also makes full use of the space within the first mounting space 11, which generates more heat after the coil winding 32 is energized, fully stimulating the Maillard reaction and improving the cooking effect of the cooking appliance.

[0094] The coil winding 32 includes an upper layer winding 321 and a lower layer winding 322, the upper layer winding 321 being located above the lower layer winding 322, the number of turns of the upper layer winding 321 being different from the number of turns of the lower layer winding 322, and the upper layer winding 321 and the lower layer winding 322 having the same innermost winding diameter. By winding two layers, upper and lower, and limiting the positional relationship between the upper layer winding 321 and the lower layer winding 322, the coil assembly 3 has better electromagnetic matching parameters and achieves a better electromagnetic heating effect.

[0095] The coil holder 31 includes an upper holder 311 and a lower holder 312, which are fixed relative to each other to define a storage space 313 for the coil winding 32. The coil winding 32 is arranged in the storage space 313 for the coil winding 32 defined by the upper holder 311 and the lower holder 312. The upper holder 311 and the lower holder 312 are used to support and fix the coil winding 32, so that the coil winding 32 can be stably installed in the first mounting space 11 and the stability of the overall structure and winding shape of the coil winding 32 can be ensured. The coil winding 32 can stably form a magnetic field to heat the heating cover 4.

[0096] The upper holder 311 and / or the lower holder 312 are provided with a plurality of radial ribs 315, and in the radial direction toward the center of the inner lid 1, the width of the outer end of the radial ribs 315 is greater than the width of the inner end, and the difference between the maximum width and the minimum width ranges from 4.5 mm to 20 mm. The plurality of radial ribs 315 stably fix and support the coil winding 32 and play a role in reinforcing the upper holder 311 and the lower holder 312, and the arrangement of the radial ribs 315 can prevent the shape and structure of the coil winding 32 from being damaged.

[0097] A radiation avoidance space 314 is defined between adjacent radiation ribs 315, and the radiation avoidance space 314 not only allows radiation to be better transmitted downward to the heating lid 4, but also achieves better heat dissipation effect.

[0098] The lower holder 312 is provided with annular convex ribs 316, which can reinforce the structural strength of the lower holder 312 and enable the coil windings 32 to be installed more stably. On the other hand, the coil windings 32 are fitted onto the outer surface of the convex ribs 316, and the shape of the coil windings 32 surrounded by the outer contour of the convex ribs 316 is controlled. Moreover, the installation of the convex ribs 316 allows the coil windings 32 to be distributed evenly, ensuring the structural stability of the coil windings 32.

[0099] Referring to FIG. 4, the glass partition plate 12 is provided below the coil assembly 3, and radiation generated from the coil winding 32 can be transmitted through the glass partition plate 12 to the heating plate, while heat generated from the heating cover 4 is less likely to be transmitted to the coil assembly 3 through the glass, thereby improving the heat utilization rate.

[0100] Furthermore, an aperture 121 is further provided in the glass partition 12, which avoids the temperature regulator assembly 50 so that the temperature regulator assembly 50 can detect the temperature of the heating plate.

[0101] As shown in Figures 3 and 6, a groove 41 is provided on the upper surface of the heating lid 4, and the bottom of the groove 41 protrudes toward the inner pot so that the orthogonal projection of the coil winding 32 on the heating lid 4 covers the groove 41, allowing the heating lid 4 at the groove 41 to obtain sufficient heat, reducing condensation at the bottom of the groove 41 and preventing the condensation from dripping onto the food and affecting the texture of the food, thereby ensuring the cooking effect of the food.

[0102] The groove 41 has a through-hole 42 which corresponds to the position of the opening 121 in the glass partition plate 12 and the temperature regulator assembly 50. The temperature sensor 5 is closely attached to the through-hole 42, allowing the temperature of the steam and the temperature of the heating plate to be detected simultaneously, thereby enabling more accurate temperature control of the cooking appliance.

[0103] A cooking appliance according to another aspect of the present application includes the cooking appliance lid assembly 100. By adopting the cooking appliance lid assembly 100, the overall structure of the cooking appliance becomes more compact, the degree of integration is higher, and the cooking effect is better.
