The second heating group is the same.

Of course, in other designs, it is also possible to provide that the power ratings of parts of the first heating groups are different, i.e. the power ratings of different first heating groups may be the same or different. The second heating group is the same.

In one possible design, the cooking appliance further comprises: the tray is arranged in the cooking cavity and is positioned between the first heating group and the second heating group.

In this embodiment, each controller is used to control the first heating element 300 located within one first reflective cavity 212, i.e., the first heating element 300 located within a different first reflective cavity 212 is controlled by a different controller. The controller can control the first heating members 300 located in the different first reflecting cavities 212 to operate with the same or different power, so that independent temperature control of the different first heat radiation areas can be realized, and the temperatures of the different first heat radiation areas can be different, thereby being beneficial to meeting the cooking demands of users.

In one possible embodiment, the number of first heating elements 300 located within any two first reflective cavities 212 is different; and/or the power ratings of the first heating members 300 located within any two of the first reflective cavities 212 are different.

As shown in connection with fig. 2, 3 and 4, in one possible embodiment, the cooking appliance further comprises: at least two second reflecting portions 221 and at least two second heating members 400, the at least two second reflecting portions 221 being disposed in the cooking cavity 110, the second reflecting portions 221 being provided with second reflecting cavities 222; the first heating element 300 is disposed at the top of the cooking cavity 110, the second heating element 400 is disposed at the bottom of the cooking cavity 110, the second heating element 400 is disposed in the second reflecting cavities 222, the second heat radiation areas of the second heating elements 400 disposed in any two second reflecting cavities 222 are at most partially overlapped, and the second heating elements 400 in different second reflecting cavities 222 independently generate heat.

In this embodiment, at least two second reflecting portions 221 are further provided in the cooking cavity 110, and each second reflecting portion 221 is provided with a second reflecting cavity 222. The second heating elements 400 are located in the second reflective cavities 222, and specifically, each second reflective cavity 222 has a second heating element 400 therein. The second reflective cavity 222 can collect heat of the second heating member 400 such that heat generated by the second heating member 400 is thermally radiated toward a designated direction. By providing at least two second reflecting cavities 222 such that heat generated by different second heating members 400 can be radiated in different directions, a plurality of second heat radiating areas can be formed in the cooking cavity 110.

Each second reflective cavity 222 is provided with a second opening, and the second openings of at least two second reflective cavities 222 are oriented differently, such that the second heating elements 400 located within different second reflective cavities 222 radiate heat toward different areas.

The first heat radiation area of the first heating member 300 and the second heat radiation area of the second heating member 400 may overlap or may be staggered. For example, when the number of the first reflecting cavities 212 is 5, 5 first heat radiating areas are formed in the cooking cavity 110 by the reflecting action of the first reflecting cavities 212, and the number of the second reflecting cavities 222 is also 5, and one first heat radiating area corresponds to one second heat radiating area, so that in the case that the number of the first reflecting cavities 212 and the number of the second reflecting cavities 222 are also 5, the number of the heat radiating areas is 5. When the first heat radiation area and the second heat radiation area are staggered, the number of heat radiation areas in the cooking cavity 110 is 10.

By adding the second heating member 400, the heating effect of the cooking appliance on the food can be further improved.

Since the first heating member 300 is disposed at the top of the cooking cavity 110 and the second heating member 400 is disposed at the bottom of the cooking cavity 110, the food material is heated between the first heating member 300 and the second heating member 400, so that the food material can be horizontally placed into the cooking cavity 110, and convenience in cooking the food material is improved.

The first heating member 300 and the second heating member 400 have the same structure, so that the second heating member 400 is disposed at the top of the cooking cavity 110 and the principle that the first heating member 300 is disposed at the bottom of the cooking cavity 110 is the same as described above.

The second heating elements 400 in the different second reflecting cavities 222 independently generate heat, so that the temperatures of the different second heat radiation areas can be different, and a user can cook food materials in the second heat radiation areas with different temperatures, which is beneficial to meeting the cooking demands of the user.

In one possible embodiment, the number of second heating elements 400 located within any two second reflective cavities 222 is different; and/or the power ratings of the second heating members 400 located within any two of the second reflective cavities 222 are different.

In this embodiment, the number of the second heating elements 400 located in the different second reflective cavities 222 is different, and when the second heating elements 400 operate at the rated power, the temperatures of the different second heat radiation areas are different, so that the user can implement different cooking functions in the different heat radiation areas, which is beneficial to improving the use experience of the user.

Of course, in other embodiments, the number of second heating elements 400 located in a portion of the second reflective cavity 222 may be different, i.e., the number of second heating elements 400 located in different second reflective cavities 222 may be the same or different.

The rated powers of the second heating elements 400 located in the different second reflecting cavities 222 are different, and when the second heating elements 400 work at the rated powers, the temperatures of the different second heat radiation areas are different, so that a user can realize different cooking functions in the different heat radiation areas, and the use experience of the user is improved.

Of course, in other embodiments, it is also possible to provide that the power rating of the second heating elements 400 located in part of the second reflective cavities 222 is different, i.e. the power rating of the second heating elements 400 located in different second reflective cavities 222 may be the same or different.

In one possible application, the first heating element 300 is a first heating tube and the second heating element 400 is a second heating tube. The heating element is arranged in a tubular shape, so that the installation convenience of the heating element can be improved, and the radiation area of the heat radiation area can be improved.

As shown in connection with fig. 2, 3 and 4, in one possible embodiment, the first reflective cavity 212 is flared from the top of the cooking cavity 110 to the bottom of the cooking cavity 110; and/or from the bottom of the cooking cavity 110 to the top of the cooking cavity 110, the second reflective cavity 222 is flared.

In this embodiment, the first reflective cavity 212 is flared, i.e., the cross-sectional area of the first reflective cavity 212 increases from top to bottom, from the top to bottom of the cooking cavity 110. Since the first heating member 300 is disposed at the top of the cooking cavity 110, heat generated from the first heating member 300 can be radiated toward the middle of the cooking cavity 110 by the condensing action of the first reflecting cavity 212. The first reflecting cavity 212 is formed in a flared shape to ensure smooth heat transfer, and to increase the radiation area of each heat radiation area to ensure that the heat radiation area can cover the area to be heated of the cooking cavity 110.

Likewise, the second reflective cavity 222 is flared, i.e., the cross-sectional area of the second reflective cavity 222 increases from bottom to top, from the bottom of the cooking cavity 110. Since the second heating member 400 is disposed at the bottom of the cooking cavity 110, heat generated from the second heating member 400 can be radiated toward the middle of the cooking cavity 110 by the condensing action of the second reflecting cavity 222. The second reflecting cavity 222 is formed in a flared shape to ensure smooth heat transfer, and to increase the radiation area of each heat radiation area to ensure that the heat radiation area covers the area to be heated of the cooking cavity 110.

In one possible embodiment, the cooking appliance further comprises: the storage box (not shown in the drawing) is arranged in the cooking cavity 110, the storage box is positioned below the second reflecting cavity 222, an opening is arranged at the bottom of the second reflecting cavity 222, and the opening is communicated with the storage box.

In this embodiment, during the cooking process of the food material by the cooking apparatus, residues of the food material may fall into the second reflective cavity 222, and in order to avoid accumulation of the food material in the second reflective cavity 222, the bottom of the second reflective cavity 222 is designed to be open. When the food residue falls into the second reflective cavity 222, the food residue is discharged out of the second reflective cavity 222 through the bottom opening of the second reflective cavity 222, the storage box is located below the second reflective cavity 222, and the food residue discharged out of the second reflective cavity 222 falls into the storage box. The receiver is unified to be collected food material residue, and the user of being convenient for clear up.

Through set up the opening in the bottom of second reflection chamber 222, avoid eating material residue to pile up in second reflection chamber 222, can reduce the clearance degree of difficulty of user to second reflection chamber 222. Moreover, since the second heating element 400 is disposed in the second reflecting cavity 222, the temperature in the second reflecting cavity 222 is high, and safety accidents are likely to occur when food material residues are accumulated in the second reflecting cavity 222 for a long time. Therefore, providing an opening at the bottom of the second reflective cavity 222 can improve the safety of the cooking appliance when in operation.

In one possible embodiment, the receiving box is detachably provided to the cooking cavity 110.

In this embodiment, the storage box can be taken out of the cooking cavity 110, so that the user can uniformly pour the food material residues in the storage box. Illustratively, a sliding rail may be disposed in the cooking cavity 110, the storage box may slide along the sliding rail, and after the cooking appliance is used for a period of time, a user may take the storage box out of the cooking cavity 110, so as to avoid the storage box from accumulating excessive food residues and blocking the opening of the second reflective cavity 222. Take out receiver in cooking cavity 110, can improve the clearance convenience of user to food material residue.

As shown in connection with fig. 2, 3 and 4, in one possible embodiment, two adjacent first reflecting portions 211 are disposed at intervals; and/or two adjacent second reflecting portions 221 are spaced apart.

In this embodiment, the adjacent two first reflecting portions 211 are spaced apart, so that the interval between the first heating members 300 in the adjacent two first reflecting cavities 212 can be increased. As the distance between the first heating elements 300 in the adjacent two first reflecting cavities 212 increases, the contact ratio between the first heat radiation areas of the first heating elements 300 in the adjacent two first reflecting cavities 212 is smaller or no contact occurs, so that interference between the adjacent two first heat radiation areas can be avoided, and the independence of the adjacent two first heat radiation areas can be improved. When different food materials are placed in different first heat radiation areas, the food materials can be prevented from being influenced by the adjacent first heat radiation areas, and the cooking effect of the food materials is improved.

Likewise, adjacent two second reflecting portions 221 may be spaced apart, so that the interval of the second heating member 400 in the adjacent two second reflecting cavities 222 may be increased. As the distance between the second heating elements 400 in the two adjacent second reflecting cavities 222 increases, the second heat radiation areas of the second heating elements 400 in the two adjacent second reflecting cavities 222 have smaller overlapping ratio or do not overlap, so that interference between the two adjacent second heat radiation areas can be avoided, the independence of the two adjacent second heat radiation areas can be improved, and the cooking effect on food materials is further improved.

In this embodiment, at least two first reflective portions 211 are formed on the first sheet metal portion 210, and at least two second reflective portions 221 are formed on the second sheet metal portion 220. When the first sheet metal part 210 and the second sheet metal part 220 are assembled, the first sheet metal part 210 and the second sheet metal part 220 are separated, so that the first sheet metal part 210 and the second sheet metal part 220 can be mounted respectively. Compare in installing whole sheet metal component 200, when installing first sheet metal part 210 and second sheet metal part 220 in proper order, can be convenient for adjust the position of first sheet metal part 210 and second sheet metal part 220 to can improve the installation convenience to first sheet metal part 210 and second sheet metal part 220.

After the first sheet metal portion 210 and the second sheet metal portion 220 are mounted, the first sheet metal portion 210 and the second sheet metal portion 220 may be separated from each other, or the first sheet metal portion 210 and the second sheet metal portion 220 may be connected by a connector.

In one possible embodiment, the sheet metal part 200 is detachably connected to the cooking cavity 110.

In this embodiment, the sheet metal part 200 can be detached from the cooking cavity 110, and when the first reflecting portion 211 and the second reflecting portion 221 are damaged, the sheet metal part 200 can be detached so as to facilitate maintenance of the structure on the sheet metal part 200. Moreover, because the sheet metal part 200 can be detached for maintenance, the condition that the whole cooking utensil needs to be integrally maintained due to the damage of the sheet metal part 200 is avoided. The sheet metal part 200 is arranged into a detachable structure, so that the maintenance convenience of the cooking appliance can be improved, and the maintenance cost of the cooking appliance can be reduced.
