Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1 to 4, the inner pot of the present embodiment includes: inner pot body 10, electric heating film 20 and electrode structure 30. Wherein, the electric heating film 20 is arranged on the outer surface of the inner pot body 10. The electrode structure 30 covers at least part of the electric heating film 20, the electrode structure 30 comprises a first electrode structure 31 positioned on the electric heating film 20 and a second electrode structure 32 arranged on the circumferential outer side of the first electrode structure 31, and the second electrode structures 32 are arranged at intervals along the radial direction of the inner pot.
By applying the technical scheme of the embodiment, when the water amount in the inner pot body 10 is sufficient, the first electrode structure 31 and the second electrode structure 32 farthest from the first electrode structure 31 can be electrified, and the structure enables the area, covered by the electric heating film 20, of the inner pot body 10 to be heated. When the water amount in the inner pot body 10 is low, the first electrode structure 31 and the second electrode structure 32 close to the first electrode structure 31 can be electrified, the electric heating film 20 can be heated in a partial area covering the inner pot body 10 due to the structure, and an area without water in the inner pot corresponding to the electric heating film can not be heated, so that the condition of overhigh temperature rise of the electric heating film is avoided, and the service life of the electric heating film is ensured.
In addition, in the present embodiment, in order to enable the food in the inner pan to be boiled, at least two of the plurality of second electrode structures 32 may be energized, and the first electrode structure 31 may not be energized. For the sake of simplicity in the following description, the second electrode structure 32 of the energized second electrode structures 32 that is closer to the first electrode structure 31 is referred to as the inner electrode, and the second electrode structure 32 of the energized second electrode structures 32 that is further away from the first electrode structure 31 is referred to as the outer electrode. Under the condition that at least two of the second electrode structures 32 are electrified and the first electrode structure 31 is not electrified, the electric heating film between the first electrode structure 31 and the inner side electrode does not continuously heat (namely, the electric heating film is an unheated area), and the temperature of the area is lower; the electric heating film between the inner side electrode and the outer side electrode generates heat (namely, a heating area), and the temperature of the area is higher, so that temperature difference occurs. The food is turned over from the heating area with high temperature to the non-heating area with low temperature, so that all the food can be sufficiently heated, and a better heating effect is realized.
It should be noted that, in the present embodiment, the electrode structure 30 directly covers the electrothermal film 20, and on one hand, the electrode structure 30 does not occupy the laying space of the electrothermal film 20, so that the laying area of the electrothermal film 20 can be maximized, and the cooking effect is improved; on the other hand, the above structure is more convenient to control, for example, when the inner pot needs to be heated normally, the first electrode structure 31 and the outer electrode can be directly electrified. It is not necessary to perform the energizing operation for the other electrodes in the middle.
As shown in fig. 1 and 3, in the present embodiment, the electric heating film 20 is disposed on the bottom of the inner pan body 10, and the first electrode structure 31 is located at the center of the bottom. In the above structure, the bottom of the pan is covered by the electric heating film 20, so the heating effect of the food is better.
In the present embodiment, one of the first electrode structure 31 or the plurality of second electrode structures 32 is a common electrode. Different heating strategies can be realized by adjusting the common electrode, and different heating effects can be realized. Specifically, in the present embodiment, the second electrode structures 32 are two spaced apart. When the inner pot is manufactured, the electric heating film 20 is attached to the bottom of the inner pot body 10, and then the first electrode structure 31 and the two second electrode structures 32 are respectively arranged on the electric heating film 20. The electrothermal film between the first electrode structure 31 and the second electrode structure 32 close to the first electrode structure 31 forms a first heating area (including the area of the heating film covered by the first electrode structure 31, the area between the first electrode structure 31 and the second electrode structure 32, and the area of the heating film covered by the second electrode structure 32 close to the first electrode structure 31), and the electrothermal film between the two second electrode structures 32 forms a second heating area (including the area between the two second electrode structures 32 and the area of the heating film covered by the second electrode structure 32 far from the first electrode structure 31). In the case of using the first electrode structure 31 as a common electrode, if the amount of water in the inner pot body 10 is sufficient, the first electrode structure 31 and the second electrode structure 32 farthest from the first electrode structure 31 can be energized, so that the first heating area and the second heating area are heated simultaneously. If the water content in the inner pot body 10 is extremely low, for example, the liquid level drops to the first heating area, the second electrode structure 32 far away from the first electrode structure 31 can be not electrified, the first heating area is normally heated at the moment, the second heating area is not heated any more, the phenomenon of dry burning of the second heating area is avoided, and the service life of the electric heating film is ensured. Under the condition that the second electrode structures 32 close to the first electrode structures 31 in the two second electrode structures 32 are used as common electrodes, if the water amount in the inner pot body 10 is extremely low, the second electrode structures 32 far away from the first electrode structures 31 can be not electrified, the first heating area is normally heated, the second heating area is not heated any more, the phenomenon of dry burning of the second heating area is avoided, and the service life of the electric heating film is ensured. If boiling tumbling of the water in the inner pot body 10 is required, the two second electrode structures 32 are energized, and the first electrode structure 31 is not energized any more. At the moment, the second heating area is heated, the first heating area is not heated any more, and the structure is beneficial to rolling of food towards the center of the pot, so that the food is more delicious. In the case that the second electrode structure 32 far from the first electrode structure 31 of the two second electrode structures 32 is used as a common electrode, if the water amount in the inner pot body 10 is sufficient, the first electrode structure 31 and the second electrode structure 32 farthest from the first electrode structure 31 can be electrified, so that the first heating area and the second heating area are heated simultaneously. If boiling tumbling of the water in the inner pot body 10 is required, the two second electrode structures 32 are energized, and the first electrode structure 31 is not energized any more. At the moment, the second heating area is heated, the first heating area is not heated any more, and the structure is beneficial to rolling of food towards the center of the pot, so that the food is more delicious.

When the liquid level is lower than the first height A, the second electrode structure 32 which is closest to the first electrode structure 31 in the plurality of second electrode structures 32 can be electrified with the first electrode structure 31, so that the time for dry burning the electric heating film is reduced, and the service life of the electric heating film is prolonged. It should be noted that, the second electrode structures 32 with a large number are provided, so that the dry-burning time of the electrothermal film in each area can be reduced, and the service life of the electrothermal film can be further prolonged.
