In order to avoid the above problem, in the present embodiment, the heat insulation assembly 20 is disposed between the tray body 40 and the heat generating member 30, as shown in fig. 4 to 6, the heat insulation assembly 20 may include a heat insulation tray 22 and a heat insulation ring 21, the heat insulation tray 22 is disposed in the heat insulation ring 21, a side of the heat insulation tray 22 facing the heat generating member 30 and the heat insulation ring 21 enclose a receiving area, and when the heat generating member 30 is located in the receiving area, a surface of the heat generating member 30 is lower than or flush with a surface of the heat insulation ring 21.

The heat insulation tray 22 may be disposed on a side of the heat generating member 30 away from the heat generating surface, and the heat insulation tray 22 may be located on a side of the heat generating member 30 away from the panel (not shown) based on the heat generating surface of the heat generating member 30 facing the panel of the cooking appliance. In this embodiment, taking the heat insulating tray 22 located at one side of the bottom of the heat generating component 30 as an example for illustration, the heat insulating tray 22 can effectively block the heat of the heat generating component 30 from radiating towards one side of the heat generating surface away from the heat generating component 30, on one hand, the heat of the heat generating component 30 can be prevented from influencing the stability of the structure at one side of the bottom shell 10 of the cooking appliance, on the other hand, the heat of the heat generating component 30 can be ensured to radiate towards one side of the heat generating surface, a guiding effect is formed on the heat, and thus the heating effect of the heat.

The heat insulation disc 22 is arranged in the heat insulation ring 21, so that the excessive thickness of the heat insulation assembly 20 when the heat insulation disc and the heat insulation ring are overlapped can be avoided, and the overall thickness of the heating disc is favorably reduced. The heat insulation ring 21 is arranged around the periphery of the heating element 30, and the surface height of the heat insulation ring 21 is higher than that of the heating element 30, so that the heat of the heating element 30 can be effectively prevented from radiating towards one side of the periphery of the heating element 30, the influence of the heat on electronic elements in the inner cavity is reduced, and the working stability of the electronic elements is maintained.

Wherein, the thickness of at least part partition heat ring 21 is greater than thermal-insulated dish 22, like this when thermal-insulated ring 21 and thermal-insulated dish 22 assemble the back, both can form the great structure of thickness in the higher position of thermal-insulated ring 21 thickness to effectively strengthen the intensity of thermal-insulated ring 21, guaranteed generate heat the stability of 30 assembly and thermal-insulated.

In the pressing process, the manufacturing processes of the heat insulation ring 21 and the heat insulation disc 22 may differ according to the difference in the arrangement of the heat insulation ring and the heat insulation disc 22, and since the heat generating member 30 is directly arranged on the heat insulation disc 22 in the assembling process of the heat generation disc, when the hardness of the heat insulation disc 22 is too high, the heat generating member 30 is not easily fixed on the heat insulation disc 22, and thus the hardness of the heat insulation disc 22 in the pressing process is relatively small. And the heat insulating ring 21 can contact with the panel after the assembly is completed, and the panel can be placed with a process to be heated, so that the panel bears a certain weight, when the hardness of the heat insulating ring 21 is smaller, the panel is weighted to extrude the heat insulating ring 21, so that the heat insulating ring 21 is damaged, and the hardness of the heat insulating ring 21 is set to be larger so as to meet the requirements of the structure and the performance of the heating plate.

Specifically, referring to fig. 6, at least one first avoidance notch 23 is formed in the heat insulation assembly 20, the heating element 30 includes a coiled heating wire and a connector fixing seat 31, and a connection port 33 of the heating wire is disposed in the connector fixing seat 31; the heating element 30 is provided with a temperature measuring element 32;

when the heat insulation assembly 20 is arranged between the heat generating member 30 and the tray body 40, the connecting line of the interface fixing seat 31 and/or the temperature measuring member 32 is positioned in the first avoiding gap 23. Specifically, the first avoidance gap 23 is located on the heat insulation ring 21.

It should be noted that, based on that when the heat generating member 30 is disposed in the accommodating area, the surface of the heat insulating ring 21 is higher than or flush with the surface of the heat generating member 30, so that the interface fixing seat 31 in the heat generating member 30 is located in the first avoiding notch 23, so as to ensure that the heat generating member 30 is stably disposed in the accommodating area. And when the connecting wire of the temperature measuring piece 32 is led out to the control panel through one side of the heat insulation ring 21, the connecting wire can also be arranged in the first avoiding notch 23 to ensure the stable connection of the temperature measuring piece 32 and the control panel. The first avoiding gap 23 is now at a specific setting position on the heat insulating ring 21, and the depth and the specific shape of the first avoiding gap 23 may be set according to the interface fixing seat 31 and/or the connection line, which is not limited in this embodiment.

Referring to fig. 4 to 6, as an achievable embodiment, the heat insulation ring 21 includes a first ring body 211 and a second ring body 212 which are integrally formed, and the second ring body 212 is located on a side of the first ring body 211 close to the heat generating member 30.

The inner diameter of the first ring body 211 is larger than the inner diameter of the second ring body 212, the inner diameter of the first ring body 211 is equal to the outer diameter of the second ring body 212, and when the heat generating member 30 is located in the accommodating area, the heat generating member 30 is arranged in the second ring body 212; when the heat insulating assembly 20 is positioned between the heat generating member 30 and the tray body 40, the outer peripheral wall of the first ring body 211 abuts against the inner wall of the tray body 40.

In the use process of the heat insulating ring 21, the heat generating member 30 is located in the second ring body 212, and the inner peripheral wall of the second ring body 212 abuts against the outer peripheral wall of the heat insulating plate 22, so as to fix the heat insulating plate 22. The first ring body 211 is located on one side of the second ring body 212 far away from the heating element 30, so that the thickness of the second ring body 212 is increased, the surface of the heat insulation ring 21 is higher than the surface of the heating element 30, the heat of the heating element 30 can be effectively blocked by the first ring body 211 to radiate towards the peripheral direction of the heating element 30, and the influence of the heat of the heating element 30 on the electronic element in the inner cavity is reduced. The thickness of the heat insulation ring 21 is increased by the first ring body 211, the whole thickness of the heat insulation ring 21 is increased, the strength of the heat insulation ring 21 is optimized, and the structural stability is improved.

The thickness of the second ring body 212 is gradually reduced from the side close to the heat generating component 30 to the side close to the first ring body 211. Since the second ring 212 is close to the heat generating member 30 on the side where the thickness is large, the heat generating member 30 can be stably fixed by the portion having the large thickness. Based on the surface height of the first ring body 211 being higher than the surface height of the second ring body 212, the portion with smaller thickness is close to one side of the first ring body 211, which can facilitate the connection between the first ring body 211 and the second ring body 212, thereby reducing the processing difficulty of the heat insulation ring 21.

Specifically, the outer diameter of the heat insulation disc 22 is larger than that of the heat generating piece 30, and the distance between the outer peripheral wall of the heat insulation disc 22 and the outer peripheral wall of the heat generating piece 30 is 2-20 mm.

It should be noted that, the distance between the outer peripheral wall of the heat insulating tray 22 and the outer peripheral wall of the heat generating member 30 may be a distance shown in a in fig. 4 and 5, and when the distance is too small, the distance between the two is not enough to satisfy the assembling clearance, which results in a difficult assembly of the heat generating member 30 in the first ring body 211. And the first ring body 211 influences the heat of the heat generating member 30 to be radiated toward the side of the heat generating surface, thereby influencing the heating effect of the heat generating plate. When the distance between the outer peripheral wall of the heat insulating plate 22 and the outer peripheral wall of the heat generating member 30 is too large, the heat of the heat generating member 30 is radiated to the outer peripheral side of the heat generating member 30 from the gap between the two, so that the heat leaks to affect the stability of the electronic components in the inner cavity. In practical use, the user can select a specific value of the distance between the outer peripheral wall of the heat insulating tray 22 and the outer peripheral wall of the heat generating member 30 within the above range, and the specific value is not limited in the embodiment.

As another realizable embodiment, the heat insulating ring 21 of the present embodiment may also include only the first ring body 211, and when the heat insulating disk 22 is located in the heat insulating ring 21, the inner wall surface of the first ring body 211 abuts against the outer periphery of the heat insulating disk 22. The distance between the outer peripheral wall of the heat insulation plate 22 and the outer peripheral wall of the heat generating member 30 is set to be 2-20 mm.

As an alternative embodiment, the insulating disk 22 has a thickness of 8-15 mm. When the thickness of the heat insulation disc 22 is small, the mechanical strength of the heat insulation disc 22 is low, the stable installation of the heating member 30 cannot be guaranteed, the blocking effect on heat is small, the heat of the heating member 30 still influences the bottom shell 10 of the cooking appliance, and when the thickness of the heat insulation disc 22 is large, the whole thickness of the heating disc is large, and the preparation of the miniaturized cooking appliance is not facilitated. Therefore, in practical use, the thickness of the thermal insulation disk 22 can be selected by the user within the above range, and the specific value of the thickness of the thermal insulation disk 22 is not limited in this embodiment.

Specifically, as shown in fig. 2 and 6, the tray body 40 includes a bottom plate 41 and a flange 42 surrounding the periphery of the bottom plate 41, and an end of the flange 42 extends toward the heat generating member 30.
