[0023] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0024] like Figure 1 and Figure 2 As shown, a heating device of a cooking device is provided, comprising an inner pot 1 with a cooking cavity 101, an air collecting hood 2 and a heating element 3 for heating the cooking cavity 101 are arranged on the inner pot 1, the heating element 3 cooperates with the cooking cavity 101 to form a first working state, and the heating element 3 heats the liquid or food in the cooking cavity 101; the air collecting hood 2, the inner pot 1 and the heating element 3 cooperate to form a second working state, a steam generating cavity 4 is formed between the inner pot 1, the air collecting hood 2 and the heating element 3, the heating element 3 heats the liquid in the steam generating cavity 4 and generates steam, and the steam is discharged from the air collecting hood 2.

[0025] Specifically, when the cooking device is in a first working state, the heating element 3 cooperates with the cooking cavity 101, and the heating element 3 heats the liquid or food in the cooking cavity 101; when the cooking device is in a second working state, the inner pot 1, the air collecting hood 2 and the heating element 3 together constitute a closed steam generating cavity 4. When the heating element 3 heats the liquid in the steam generating cavity 4, the liquid will quickly vaporize into steam and be discharged through the air collecting hood 2. The heating element 3 can heat the liquid to achieve cooking or steaming functions to meet the user's usage needs, thereby greatly improving the applicability of the cooking device. It has a simple structure, diverse functions and strong practicality.

[0026] Further, if Figure 1 and Figure 2 As shown, the inner pot 1 is provided with an annular recess 102 which is in communication with the cooking cavity 101 , and the gas collecting hood 2 is detachably mounted on the annular recess 102 .

[0027] Specifically, the air collecting hood 2 can be flexibly disassembled and installed on the annular recess 102, which is convenient for users to clean and maintain. When the air collecting hood 2 is covered on the annular recess 102, the annular recess 102 is used to collect liquid, so that when the heating element 3 is working, the heating element 3 heats the liquid on the annular recess 102, thereby achieving the rapid vaporization of the liquid on the annular recess 102 into steam and discharging it through the air collecting hood 2.

[0028] Further, if Figure 3 and Figure 4 As shown, the heating element 3 is arranged in the central area of ​​the bottom of the inner pot 1 and extends along the circumference of the annular recess 102 .

[0029] Specifically, the heating element 3 is arranged in the central area of ​​the bottom of the inner pot 1, and can effectively conduct heat to various parts in the inner pot to ensure that it can fully cover the cooking space in the inner pot.

[0030] It should be noted that the heating element 3 and the inner liner 1 are an integrated structure or a split structure. When the heating element 3 and the inner liner 1 are an integrated structure, they have good air tightness and thermal conductivity, which is beneficial to improving thermal efficiency and stability, and can better conduct heat to various parts in the inner liner 1; when the heating element 3 and the inner liner 1 are a split structure, it is easier to operate during maintenance and replacement, thereby increasing the service life.

[0031] Further, if Figure 2 As shown, the projection area of ​​the gas collecting hood 2 on the inner container 1 at least covers the annular recess 102 .

[0032] Specifically, the projected area of ​​the gas collecting hood 2 is greater than or equal to the projected area of ​​the annular recess 102 to ensure that it can completely cover the recess 102 and enclose it in a sealed space, so that the heating element 3 heats the liquid on the annular recess 102, thereby achieving rapid vaporization into steam and being discharged through the gas collecting hood 2.

[0033] Further, if Figure 5 As shown, the distance from the annular recess 102 to the inner surface of the inner container 1 is H, 0mm≤H≤10mm.

[0034] If the distance between the annular depression 102 and the inner surface of the inner pot 1 is too large or too small, it will affect the normal use of the cooking device. If the distance is too large, it may cause the steam to be generated slowly, affecting the heating efficiency; if the distance is too small, it may cause dry burning.

[0035] Preferably, the distance H from the annular recess 102 to the inner surface of the liner 1 is 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0036] Further, if Figure 3 and Figure 5 As shown, the annular depression 102 is formed by the upper surface of the inner container 1 being depressed downward.

[0037] Further, if Figure 2 As shown, the air collecting hood 2 has an air inlet end 201 and an air outlet end 202 . A sealing member 5 is disposed on the air inlet end 201 . The air collecting hood 2 is spaced apart from the annular recess 102 by the sealing member 5 .

[0038] Specifically, the setting of the seal 5 can improve the sealing between the air collecting hood 2 and the annular recess 102, and can prevent the air inlet end 201 of the air collecting hood 2 from directly contacting the annular recess 102, thereby preventing damage to the air collecting hood 2 in the case of dry burning, and improving safety performance.

[0039] Further, if Figure 2 As shown, a water inlet 1021 is provided on the annular recess 102, and a water replenishment hole 501 is provided on the sealing member 5. The water replenishment hole 501 is connected to the water inlet 1021 and the cooking cavity 101, and the liquid in the cooking cavity 101 flows into the annular recess 102 through the water inlet 1021 and the water replenishment hole 501.

[0040] Specifically, a water inlet 1021 is provided on the annular recess 102, and the water inlet 1021 is mainly used for the water in the cooking cavity 101 to flow into the annular recess 102, and the water replenishment hole 501 on the sealing member 5 is connected with the water inlet 1021 and the cooking cavity 101, so as to ensure that the water can flow smoothly into the annular recess 102.

[0041] Further, if Figure 2 As shown, a juice receiving tray 6 is disposed on the gas outlet end 202 , and a steamer assembly 7 is disposed on the juice receiving tray 6 ; an upwardly extending edge 601 is disposed on the juice receiving tray 6 , and the edge 601 is located outside the gas outlet end 202 .

[0042] Specifically, the function of the juice collecting tray 6 is to collect the soup of the food or the condensed water of the steam on the steamer assembly 7 generated during the cooking process. The steamer assembly 7 includes a steamer 701 detachably mounted on the juice collecting tray 6 and a steaming cover 702 that can cover the top opening of the inner pot 1 and / or the steamer 701. The steaming cover 702 is provided with an exhaust port 7021 for discharging steam. The steamer 701 is arranged in multiple layers, and two adjacent steamers 701 are interconnected.

[0043] Furthermore, the heating element 3 at least includes a heating tube, a PTC heater, a thick film heater or a ceramic heating plate.
