Referring to fig. 1 to 6, the cooking appliance provided by the embodiment of the utility model includes a bottom shell 10 and a panel 20, and the bottom shell 10 and the panel 20 together enclose an accommodating cavity. The heating plate 30 and the cooling fan 40 are arranged in the accommodating cavity, and an air outlet of the cooling fan 40 faces the heating plate 30. At least two fixing assemblies 50 are provided on an inner wall surface of the bottom case 10, and the heating pan 30 is selectively provided on at least two fixing assemblies 50.

The cooking utensil of the utility model can be an induction cooker, an electric ceramic oven and the like, wherein the heating plate can be a coil plate in the induction cooker or a heating coil in the electric ceramic oven. The present embodiment will be described in detail with reference to an induction cooker as an example. Referring to fig. 5 and 6, the heat dissipation fan 40, the heating plate 30, the circuit board 70, the power line 80, and the lamp panel 90 are reasonably arranged in the accommodating cavity defined by the panel 20 and the bottom case 10. Wherein, arrows in fig. 5 and fig. 6 indicate the flow direction of the heat dissipating air, the heat dissipating fan 40 is located at the lower left of the bottom casing 10, the heating plate 30 is located at the middle of the bottom casing 10, and an air outlet (not shown in the figures) of the heat dissipating fan 40 faces the heating plate 30, so as to promote heat dissipation and control the temperature of the heating plate.

In order to adapt to heating plates 30 having different outer diameters, at least two fixing assemblies 50, including a first fixing assembly 51 and a second fixing assembly 52, are provided on the bottom shell 10, as shown in fig. 1 to 4. The first fixing member 51 forms a first fixing center 531 on the bottom case, and the second fixing member 52 forms a second fixing center 541 on the bottom case. The first fixing component 51 and the second fixing component 52 are respectively used for fixing the heating plates 30 with different outer diameters, and the outer diameter of the heating plate 30 fixed on the first fixing component 51 is smaller than the outer diameter of the heating plate 30 fixed on the second fixing component 52; the first fixed center 531 is located at a side of the second fixed center 541 close to the radiator fan 40.

Specifically, referring to fig. 3, the first fixing assembly 51 includes at least three first fixing members 51a, 51b, and 51c, the at least three first fixing members 51a, 51b, and 51c enclose a first circle 53, and a center of the first circle 53 forms a first fixing center 531. Referring to fig. 3 and 6, the heating plate 30 fixed to the first fixing member 51 is a small heating plate 31, and the center of the small heating plate 31 is disposed coaxially with the first fixing center 531. In the above arrangement, the three first fixing members 51a, 51b, and 51c can form a stable supporting structure to stably support the heating plate, thereby improving the firmness of component installation; the heating plate is supported to be parallel to the panel and the bottom shell, so that the heating uniformity of the cooking appliance is ensured.

Similarly, referring to fig. 2, the second fixing assembly 52 includes at least three second fixing members 52a, 52b, 52c, the at least three second fixing members 52a, 52b, 52c enclose a second circle 54, and the center of the second circle 54 forms a second fixing center 541. Referring to fig. 2 and 5, the heating pan 30 fixed to the second fixing member 52 is a large heating pan 32, and the center of the large heating pan 32 is coaxially disposed with the second fixing center 541. In the above arrangement, the three second fixing members 52a, 52b, and 52c can form a stable support structure to stably support the heating plate, thereby improving the firmness of component installation; the heating plate is supported to be parallel to the panel and the bottom shell, so that the heating uniformity of the cooking appliance is ensured.

Further, referring to fig. 4, the first fixing center 531 is located on the side of the second fixing center 541 close to the heat dissipation fan 40, so that the small heating plate 31 can be closer to the heat dissipation fan 40, and the heat dissipation effect is improved. Specifically, in order to arrange the large heating plate 32 and the small heating plate 31 on the bottom case 10 reasonably, and to achieve a good heat dissipation effect, the distance between the first fixing center 531 and the second fixing center 541 is set to be in the range of 10-30mm, i.e., D1 shown in fig. 4, and the specific value of the distance may be 15mm, 20mm, or 25 mm. The above-mentioned too large interval may cause a difference between the mounting positions of other components such as the heat dissipation fan 40 when the small heating plate 31 is assembled and the mounting positions of other components such as the heat dissipation fan 40 when the large heating plate 32 is assembled, which may not make the bottom case 10 have versatility, and increase the overall volume of the cooking appliance. The small distance cannot improve the heat dissipation problem of the small heating plate 31, and thus the safety and efficiency of the cooking appliance are affected. In practical use, the user can select a specific value of the distance within the above range according to needs, which is not limited in this embodiment.

Further, the outer peripheral edge of the heating pan 30 fixed to the first fixing member 51 is connected to the first fixing members 51a, 51b, 51 c; the heating plate 30 fixed to the first fixing member 51 has an outer peripheral edge coinciding with an edge of the first circle 53. Similarly, the heating plate 30 fixed to the second fixing member 52 has its outer periphery connected to the second fixing members 52a, 52b, 52 c; the outer periphery of the hotplate 30 fixed on the second fixing assembly 52 coincides with the edge of the second circle 54. On one hand, the heating plate is provided with a connecting structure, such as a support lug, on the outer periphery, but is not provided with a connecting structure on the plate surface of the heating plate, and in order to realize the assembly of the heating plate, a fixing component 50 is required to be correspondingly arranged on the bottom shell, which is beneficial to the assembly stability; on the other hand, the fixed connection structure is arranged at the edge, so that the wind blown to the heating plate 30 by the cooling fan 40 is prevented from being blocked by the fixing component 50, and the cooling effect is improved.

Wherein, the distance between the first circle 53 and the radiator fan mounting center 41, as shown as D2 in fig. 3, is the distance between the edge of the first circle 53 and the radiator fan mounting center 41. The spacing is set in the range of 40-60mm, and the specific value of the spacing may be 45mm, 50mm or 55 mm. The above-mentioned too large interval may cause a long distance from the heat dissipation fan 40 when the small heating plate 31 is installed, resulting in a poor heat dissipation effect and a failure to ensure the safety of the cooking appliance. The above-mentioned too small interval can lead to the panel being heated unevenly or the heat dissipation too much, can not guarantee the high efficiency that cooking utensil used. In practical use, the user can select a specific value of the distance within the above range according to needs, which is not limited in this embodiment.

Similarly, to ensure the safety and efficiency of the cooking appliance equipped with the large heating plate 32, the distance between the second circle 54 and the assembly center 41 of the heat dissipation fan is set to be in the range of 40-80mm, i.e., D3 as shown in fig. 2, D3 is the distance between the edge of the second circle 54 and the assembly center 41 of the heat dissipation fan, and the specific value of the distance may be 50mm, 60mm or 70 mm.

Further, the projection of the first circle 53 on the bottom wall of the bottom shell 10 at least partially coincides with the projection of the second circle 54 on the bottom wall of the bottom shell 10. That is, the fitting area of the large heating pan 32 partially coincides with the fitting area of the small heating pan 31. On one hand, the heating plates 30 in different types of cooking appliances may have different outer diameters, but have basically the same assembly position, and are all positioned in the middle of the cooking appliance panel 20, so that the pot body can be conveniently supported and uniformly heated; on the other hand, the assembly area of the large heating plate 32 and the assembly area of the small heating plate 31 are partially overlapped, so that the structure of the bottom shell 10 is simplified, the blank area on the bottom shell 10 is fully utilized while the arrangement positions of most parts are not changed, and the integration level of the cooking utensil is improved; by properly adjusting the distribution area of the heating plate 30, the structure on the bottom shell 10 can be adapted to the assembly of the large heating plate 32 and the small heating plate 31, the universality of the bottom shell 10 is improved, the production process is simplified, and the production cost is reduced.

The air guide assembly 60 is an important functional component for achieving good heat dissipation.

Specifically, referring to fig. 3 and 6, the second air guide 62 is disposed around the small heating plate 31, and the first end 62a of the second air guide may be connected to the sidewall structure of the bottom casing 10 or the bottom wall structure of the bottom casing 10, so as to concentrate the air blown by the heat dissipation fan 40 toward the small heating plate 31, thereby improving the heat dissipation effect.

Further, referring to fig. 1, the second air guide 62 is located on a side of the first air guide 61 close to the heating pan 30; the second air guide member 62 has a length shorter than that of the first air guide member 61. Specifically, in order to avoid an assembly failure, the mounting position of the first wind guide 61 is set outside the area of the second circle 54; the second air guide 62 is a detachable structure, and the mounting position of the second air guide 62 is set outside the area of the first circle 53. With the arrangement, when the large heating plate 32 is assembled, the second air guide piece 62 can be unloaded, so that the problem that the second air guide piece obstructs the assembly of the large heating plate 32 is avoided; when the small heating plate 31 is assembled, the second air guide member 62 is installed, and the second air guide member 62 is closer to the small heating plate than the first air guide member 61, so that the air blown out by the cooling fan 40 is concentrated towards the small heating plate 31, and the heat dissipation effect is improved.

The second air guide member 62 has a length shorter than that of the first air guide member 61. On one hand, when the small heating plate 31 is assembled, the first air guide piece 61 can also play a role of guiding air for the small heating plate 31, so that the second air guide piece 62 does not need to be extended for a long time, the functions of all parts are fully utilized, and the structure is simplified to a certain extent; on the other hand, the second air guide 62 may be prevented from extending by the first fixing member 51a and the second fixing member 52 a.

Further, referring to fig. 1 to 4, a third air guide 63 is disposed on an inner wall surface of the bottom case 10, a first end 63a of the third air guide is disposed near the heat dissipation fan 40, and a second end 63b of the third air guide extends toward the circuit board 70 and has a distance from the circuit board 70; the third air guide 63 is located on the side of the heating plate 30 close to the circuit board 70, and the first air guide 61 and the second air guide 62 are located on the side of the heating plate 30 far from the circuit board 70. Specifically, the third air guide member 63 is used as a common air guide member for the heating plates 30 with different outer diameters, and when the large heating plate 32 is assembled, the third air guide member 63 and the first air guide member 61 are matched and enclosed on the periphery of the large heating plate 32 to play a role in guiding air; when the small heating plate 31 is assembled, the third air guide 63, the second air guide 62 and the first air guide 61 are matched to surround the periphery of the large heating plate 32, so that the air guide function is achieved.

It is to be noted that by fitting the small heating plates 31 on the first fixing members 51a, 51b, 51c, the small heating plates 31 are brought close to the heat dissipation fan 40, and the pitch is shortened to improve the heat dissipation effect when the small heating plates 31 are fitted. Specifically, referring to fig. 1 and 4, the first fixing member 51a is offset to the upper right with respect to the second fixing member 52a in the orientation shown, because the offset to the left results in the small heating plate 31 being housed in the radiator fan 40; the first fixing member 51a is close to the air outlet of the heat dissipation fan 40 due to the right downward deviation, which hinders the air outlet and affects the structural stability. Accordingly, in the orientation shown in fig. 1, the first fixing member 51b is offset clockwise to the lower right with respect to the second fixing member 52b, and the first fixing member 51c is offset clockwise to the lower left with respect to the second fixing member 52c, so as to ensure stable support of the small heating plate 31.

Specifically, as shown in fig. 1, the first fixing member 51a and the second fixing member 52a are disposed on the same base, so as to enhance structural stability; the second wind guide 62 extends to the base, and the extension length thereof is limited by the position of the base. Reinforcing ribs are arranged on the peripheries of the first fixing piece 51b and the second fixing piece 52b, the reinforcing ribs can comprise circular ribs arranged around the first fixing piece 51b and the second fixing piece 52b, and a plurality of connecting ribs distributed in a radial mode are arranged between the first fixing piece 51b and the second fixing piece 52b and the corresponding circular ribs. The surface of the circular rib is a cambered surface, and the arrangement can reduce the resistance of the wind blown to the heating plate 30 by the heat radiation fan 40 in the flowing process as much as possible. The arrangement of the connecting ribs can play a role in enhancing the structural stability. In the specific implementation process, according to the specific position of the fixing component 50, the annular rib and the connecting rib are properly selected to enhance the structural stability, and the cambered surface is properly selected to reduce the resistance in the air flow flowing process.

Further, the top surface of the first fixing member 51 is higher than the top surface of the second fixing member 52, and the height difference between the top surface of the first fixing member 51 and the top surface of the second fixing member 52 ranges from 1 to 2.5mm, and the specific value of the spacing may be 1mm, 2mm, or 2.5 mm. The spacing between the top surface of the first fixing member 51 and the face plate 20 is in the range of 7-8mm, and the specific value of the spacing may be 7mm, 7.5mm or 8 mm. The spacing between the top surface of the second securing member 52 and the face plate 20 is in the range of 8-9.5mm, and may be of a specific value of 8mm, 9mm or 9.5 mm.

Since the small heating plate 31 has a smaller number of coils and a smaller heating area than the large heating plate 32, the small heating plate 31 can be disposed closer to the panel 20 to ensure that the two have substantially the same heating effect. That is, the first fixing component 51 is higher than the second fixing component 52, so that the small heating plate 31 can be ensured to be closer to the panel 20 than the installation position of the large heating plate 32, which is beneficial to improving the heating effect of the cooking appliance assembled with the small heating plate 31 and improving the use efficiency of the cooking appliance. Specifically, too small a distance between the first fixing member 51 and the panel 20 affects the assembly of the small heating pan 31 and the panel 20, and too large affects the heating effect of the small heating pan 31. Similarly, too small a distance between the second fixing member 52 and the panel 20 will affect the assembly of the large heating plate 32 and the panel 20, and too large a distance will affect the heating effect of the large heating plate 32. Therefore, when the heights of the first fixing unit 51 and the second fixing unit 52 are set, the thickness of the large heating plate 32 and the small heating plate 31 and the relative distance between the installation positions of the large heating plate 32 and the small heating plate 31 are reserved, so that the bottom case 10 can be applied to the installation of the large heating plate 32 and the small heating plate 31.
