[0028] Compared with the prior art, the utility model has the following beneficial effects:

[0029] In this solution, the structure of the outer ring cavity and the inner ring cavity enables the liquid gathering ring to surround the two holding areas in a circular shape, thereby centrally heating the inner ring cavity, so that less liquid in the inner ring cavity can be heated and boiled faster, allowing users to first go through the inner ring cavity to have hot pot, thereby shortening the waiting time for users to have hot pot.

[0030] The present invention divides the cooking cavity into two independent areas, the outer ring and the inner ring, by setting a liquid gathering ring, and the liquid gathering ring divides the cooking cavity into an outer ring outer ring cavity and an inner ring inner ring cavity, thereby dividing the cooking cavity into two independent areas, the outer ring and the inner ring cavity, and by setting corresponding area size limitations on the inner bottom surface of the cookware, the inner ring cavity can be effectively and quickly heated to boil, thereby greatly shortening the time it takes for the liquid in the inner ring cavity to boil, thereby greatly shortening the time users need to wait when eating hot pot.

[0031] In the present solution, the first heating part is used to independently heat the outer ring cavity, and the second heating part is used to independently heat the inner ring cavity, which not only realizes the structure of dividing the cooking cavity into two areas, but also realizes the structure of independent heating of each area. The structure of the first heating part and the second heating part can be better configured to achieve that the liquid in the inner ring cavity can be heated and boiled faster, so that the user can use the inner ring cavity to have hot pot in a shorter time, shortening the user's waiting time.

[0032] In this solution, the second heating unit is provided to effectively and centrally heat the inner ring cavity, so that the liquid in the inner ring cavity can be boiled faster than the liquid in the outer ring cavity.

[0033] In this solution, the structure of the liquid gathering ring and the cooking cavity enables the inner ring cavity to have a smaller volume than the outer ring cavity. At the same time, combined with the position distribution and structural limitation of the second heating part, the liquid in the inner ring cavity can be boiled faster, while the liquid in the outer ring cavity in the outer ring can be boiled relatively slowly, so that the user can first use the inner ring cavity to eat hot pot, thereby shortening the waiting time for the user to eat hot pot.

[0034] In this solution, the total length or total heating area formed by the first heating part, the volume of the outer ring cavity, the total length or total heating area formed by the second heating part, the volume of the inner ring cavity and other structural limitations ensure that the liquid in the inner ring cavity can be heated and boiled faster than the liquid in the outer ring cavity, thereby shortening the waiting time for users to have hot pot.

[0035] In this solution, the position limitation and structural setting of the second heating part can realize effective centralized heating of the liquid in the inner ring cavity. Combined with the smaller volume and less liquid in the inner ring cavity, the liquid in the inner ring cavity can be heated and boiled faster, shortening the waiting time for users.

[0036] In this solution, the structure of the liquid collecting ring is convenient for users to install and disassemble, which makes it convenient for users to maintain and clean the liquid collecting ring, and also convenient for users to maintain and clean the cooking cavity. The structure is simple and can greatly improve the user experience.

[0037] In this solution, the area of ​​the second cross-sectional portion of the second heating part can be larger, the distance value formed by the second cross-sectional portion of the second heating part in the radial direction can be larger, or the second heating part can have a larger power, so that the second heating part can heat and boil the liquid in the inner ring cavity faster, thereby shortening the time the user needs to wait for the liquid to boil before having hot pot, thereby improving the user's experience.

[0038] In this solution, the cooking cavity is divided into an outer ring cavity and an inner ring cavity by a liquid gathering ring, which can achieve the effect of partitioning hot pot, such as the outer ring cavity for clear soup hot pot, and the inner ring cavity for spicy hot pot, thereby achieving the effect of partitioning hot pot, which can better meet the needs of users to have hot pot in different areas and greatly improve the user's usage effect.

DETAILED DESCRIPTION

[0045] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.

[0046] Embodiment: A cooking utensil of the present invention, such as Figures 1 to 5 As shown in the structure, the cooking appliance is mainly used for users to have hot pot. Users can wait for a shorter time before having hot pot, thereby greatly improving the user's use effect of the cooking appliance.

[0047] A cooking utensil of the present invention comprises a pot 1, which is mainly configured to be detachably mounted on a utensil body 10, and is provided with a cooking cavity 101, which is used to hold food and liquid, wherein the liquid level is water, and further comprises a liquid collecting ring 2, which is configured to be annular in structure and detachably mounted in the cooking cavity 101, and the liquid collecting ring 2 is mainly configured to be detachably mounted in the cooking cavity 101, and when the liquid collecting ring 2 is installed in place, the cooking cavity 101 is The outer ring cavity 1011 and the inner ring cavity 1012 are divided into two areas when the liquid collecting ring 2 is installed in the cooking cavity 101, one of which is the outer ring cavity 1011, and the other is the inner ring cavity 1012. The outer ring cavity 1011 and the inner ring cavity 1012 are both configured to independently hold liquid. The liquid collecting ring 2 is formed so that the inner ring cavity 1012 is wrapped around the inner side of the liquid collecting ring 2, and the outer ring cavity 1011 is formed so that the liquid collecting ring 2 is wrapped around the inner side of the liquid collecting ring 2. The inner side of the outer ring cavity 1011; that is, in the spatial area of ​​the cooking cavity 101, the outer ring cavity 1011 is located at the outer ring position, the inner ring cavity 1012 is located at the inner ring position, and the liquid gathering ring 2 is located in the area between the outer ring cavity 1011 and the inner ring cavity 1012, so that the liquid gathering ring 2 divides the cooking cavity 101 into two spatial areas, so that cooking can be performed separately and independently through the outer ring cavity 1011 and the inner ring cavity 1012, that is, hot pot can be performed separately and independently; wherein, for the structural part for heating the outer ring cavity 1011 and the inner ring cavity 1012, a first heating part 3 and a second heating part 4 are arranged below the cookware 1; the first heating part 3 is located in the projection area formed by the outer ring cavity 1011 projected downward in the vertical direction to realize that the first heating part 3 heats the outer ring cavity 1011, and at least a part of the second heating part 4 is located in the projection area formed by the inner ring cavity 1012 projected downward in the vertical direction to realize that the second heating part 4 heats the inner ring cavity 1012;The first heating part 3 is formed to heat the outer annular cavity 1011 alone, and the second heating part 4 is formed to heat the inner annular cavity 1012 alone. At the same time, the area formed by the region B corresponding to the inner annular cavity 1012 on the inner bottom surface of the cookware 1 is set to be smaller than the area formed by the region A corresponding to the outer annular cavity 1011 on the inner bottom surface of the cookware 1, so that the first heating part 3 heats the region A, and the second heating part 4 heats the region B. The area formed by the region B is set to be smaller than the area formed by the region A, so that the second heating part 4 can heat the region B with a relatively small area more quickly to heat and boil the liquid in the inner annular cavity 1012 corresponding to the region B, while the region A with a relatively large area will be heated relatively more slowly, so that the time required to heat and boil the liquid in the outer annular cavity 1011 is longer, so that the liquid in the inner annular cavity 1012 can be heated and boiled faster in a shorter time, and the user can use the liquid in the inner annular cavity 1012 to have hot pot, thereby shortening the waiting time for the user to have hot pot, thereby improving the user's user experience. ;

[0048] Among them, the first heating part 3 is located at the lower part of area A to heat area A, and area A is the cavity bottom wall of the outer ring cavity 1011 on the inner bottom surface of the cookware 1; the second heating part 4 is located at the lower part of area B to heat area B, and area B is the cavity bottom wall of the inner ring cavity 1012 on the inner bottom surface of the cookware 1, so that the area area for heating by the second heating part 4 is smaller than the area area for heating by the first heating part 3, so that the liquid in the inner ring cavity 1012, that is, a small part of the liquid in the cooking cavity 101, is heated by the second heating part 4, which can shorten the time for part of the liquid to be heated and boiled. Compared with heating the liquid in the entire cooking cavity 101, the heating time required for the entire liquid in the cooking cavity 101 to be heated and boiled is shorter, so that the user can first use the liquid in the inner ring cavity 1012 to cook hot pot, which greatly shortens the waiting time of the user.

[0049] Optionally, the first heating part 3 is configured as a heating tube, and the second heating part 4 is also configured as a heating tube.

[0050] Optionally, the liquid gathering ring 2 is configured as an integral one-piece structure, that is, an integral one-piece structure in a ring shape, which facilitates the installation of the liquid gathering ring 2 or the disassembly and maintenance by the user.

[0051] Optionally, all parts of the first heating part 3 are located in the projection area formed by projecting the outer ring cavity 1011 downward in the vertical direction, so that the heat generated by heating all parts of the first heating part 3 can be used to heat the liquid in the outer ring cavity 1011.

[0052] Optionally, all parts of the second heating part 4 are located in the projection area formed by projecting the inner annular cavity 1012 downward in the vertical direction, so that the heat generated by all parts of the second heating part 4 can be used to heat the liquid in the inner annular cavity 1012.

[0053] In the present solution, the volume formed by the inner annular cavity 1012 is set to be smaller than the volume formed by the outer annular cavity 1011 and the volume formed by the inner annular cavity 1012 is set to be smaller than half of the volume formed by the cooking cavity 101. In this way, the inner annular cavity 1012 has a smaller volume than the outer annular cavity 1011, so that the inner annular cavity 1012 can hold less liquid. At the same time, there will be no problem of too little liquid in the inner annular cavity 1012 due to the small volume of the inner annular cavity 1012, so that the second heating part 4 can heat and boil the liquid in the inner annular cavity 1012 more quickly, thereby shortening the waiting time for users.

[0054] In the present embodiment, the volume formed by the inner annular cavity 1012 is set to be greater than or equal to one quarter of the volume formed by the cooking cavity 101 and the volume formed by the inner annular cavity 1012 is set to be smaller than the volume formed by the outer annular cavity 1011. In this way, the inner annular cavity 1012 has a smaller volume than the outer annular cavity 1011, so that the inner annular cavity 1012 can hold less liquid. At the same time, there will be no problem of too little liquid in the inner annular cavity 1012 due to the small volume of the inner annular cavity 1012, so that the second heating part 4 can heat and boil the liquid in the inner annular cavity 1012 more quickly, thereby shortening the waiting time for users.

[0055] Optionally, in this solution, the liquid collecting ring 2 may be installed in the cooking cavity 101 when liquid is contained in the cooking cavity 101 .

[0056] Optionally, in this solution, after the liquid collecting ring 2 is installed in the cooking cavity 101, liquid may be added to the outer ring cavity 1011 and the inner ring cavity 1012 respectively.

[0057] Optionally, the cooker can be configured as a circular structure or a square structure, and the cooking cavity can correspondingly become a circular annular cavity structure or a square annular cavity structure.

[0058] Optionally, the liquid collecting ring of the present solution is configured as a circular annular structure.

[0059] In the present embodiment, the second heating part 4 is configured to be an annular structure. The annular structure of the second heating part 4 can be configured to correspond to the annular structure of the inner ring cavity 1012, that is, both are annular structures. The annular structure can be a circular ring, a square ring, etc. The diameter formed by the inner edge position of the second heating part 4 in the annular direction is smaller than the diameter formed by the inner edge position of the liquid gathering ring 2 in the annular direction, that is, the diameter formed by the position where the inner edge position of the second heating part 4 is located is smaller than the diameter formed by the position where the inner edge position of the liquid gathering ring 2 is located, so that at least the annular area where the inner edge position of the second heating part 4 is located is located in the projection area formed by the projection of the inner ring cavity 1012 in the vertical direction downward, that is, at least the annular area where the inner edge position of the second heating part 4 is located is formed to directly heat area B, that is, at least the annular area where the inner edge position of the second heating part 4 is located is formed to directly heat the inner ring cavity 1012, thereby increasing the time for the liquid in the inner ring cavity 1012 to be heated and boiled.

[0060] And / or, in the present embodiment, the second heating part 4 is configured to be an annular structure, and the annular structure of the second heating part 4 can be configured to correspond to the annular structure of the inner ring cavity 1012, that is, both are annular structures, and the annular structure can be a circular ring, a square ring, etc., and the diameter formed by the outer edge position of the second heating part 4 in the annular direction is less than or equal to the diameter formed by the inner edge position of the liquid gathering ring 2 in the annular direction, that is, the diameter formed by the position where the outer edge position of the second heating part 4 is located is smaller than the diameter formed by the position where the inner edge position of the liquid gathering ring 2 is located, so that the annular area where the entire position part of the second heating part 4 is located is located in the projection area formed by the projection of the inner ring cavity 1012 in the vertical direction downward, that is, the annular area where the entire position part of the second heating part 4 is located is formed to directly heat the area B, that is, the annular area where the entire position part of the second heating part 4 is located is formed to directly heat the inner ring cavity 1012, thereby increasing the time for the liquid in the inner ring cavity 1012 to be heated and boiled.

[0061] Among them, the annular area where the entire position part of the second heating part 4 is located is mainly the entire area formed between the outermost end of the outer edge position of the second heating part 4 and the innermost end of the inner edge position, and the entire area in the annular direction is constituted as the annular area where the entire position part of the second heating part 4 that can be used to generate heat is located, so that the annular area where the entire position part of the second heating part 4 is located can directly heat the inner ring cavity 1012, which can effectively increase the time for the liquid in the inner ring cavity 1012 to be heated and boiled.

[0062] Optionally, in this solution, the first heating part 3 is also configured to be an annular structure.

[0063] In the present solution, in order to further enhance the speed at which the liquid in the inner ring cavity 1012 can be heated and boiled, the distance from the outer edge position on the second heating part 4 to the inner surface position of the liquid gathering ring 2 in the radial direction is smaller than the distance from the inner edge position on the first heating part 3 to the outer surface position of the liquid gathering ring 2 in the radial direction; at this time, the diameter formed by the outer edge position of the second heating part 4 can be smaller than the diameter formed by the inner surface position of the liquid gathering ring 2, so that the entire area position of the second heating part 4 is located on the inner side of the inner surface of the liquid gathering ring 2 to heat the inner ring cavity 1012. At the same time, the position of the second heating part 4 can be relatively close to the liquid gathering ring 2, while the position of the first heating part 3 can be relatively far away from the liquid gathering ring 2, so that the second heating part 4 can better concentrate heat to heat the liquid in the inner ring cavity 1012, and the first heating part 3 is located at a position relatively far away from the liquid gathering ring 2 to heat the liquid in the outer ring cavity 1011. The position setting of the second heating part 4 can shorten the time for the liquid in the inner ring cavity 1012 to be heated and boiled.

[0064] And / or, in the present solution, in order to further enhance the speed at which the liquid in the inner ring cavity 1012 can be heated and boiled, the distance from the outer edge position on the second heating portion 4 to the inner surface position of the liquid gathering ring 2 along the radial direction is set to be greater than the distance from the inner edge position on the second heating portion 4 to the central axis N of the inner ring cavity 1012 along the radial direction. At this time, the diameter formed by the outer edge position of the second heating portion 4 can be smaller than the diameter formed by the inner surface position of the liquid gathering ring 2, so that the regional position of the entire part of the second heating portion 4 is located on the inner side of the inner surface of the liquid gathering ring 2 to heat the inner ring cavity 1012. At the same time, the regional position of the entire part of the second heating portion 4 can be relatively close to the central axis N and relatively far away from the inner surface position of the liquid gathering ring 2, so that the regional position of the entire part of the second heating portion 4 that generates heat can be relatively close to the central position of the inner ring cavity 1012 for centralized heating, so as to more concentrate the heat to heat the liquid in the inner ring cavity 1012. The position setting of the second heating portion 4 can shorten the time for the liquid in the inner ring cavity 1012 to be heated and boiled.

[0065] In the present solution, the height of the liquid collecting ring 2 in the vertical direction is set to be greater than or equal to one half of the height of the cooking cavity 101 in the vertical direction, so that the inner ring cavity 1012 has a certain accommodating space area within the height range defined by the liquid collecting ring 2, that is, it has a certain volume. Under this volume, the inner ring cavity 1012 can hold a certain amount of liquid for hot pot, and at the same time prevent the volume of the inner ring cavity 1012 from being too small, resulting in too little liquid in the inner ring cavity 1012, which may easily lead to the problem of dry burning.

[0066] In the present scheme, or, the height of the liquid gathering ring 2 in the vertical direction is set to be greater than or equal to one half of the height of the cooking cavity 101 in the vertical direction and less than the height of the cooking cavity 101 in the vertical direction, so that the inner ring cavity 1012 has a certain accommodating space area within the height range defined by the liquid gathering ring 2, that is, it has a certain volume, under which the inner ring cavity 1012 can hold a certain amount of liquid for hot pot, while preventing the volume in the inner ring cavity 1012 from being too small, resulting in too little liquid in the inner ring cavity 1012, which is easy to cause dry burning; and the height of the liquid gathering ring 2 in the vertical direction is set to be less than the height of the cooking cavity 101 in the vertical direction, which can effectively prevent the problem of overflowing the pot when hot pot is used, and the boiling liquid will overflow from the inner ring cavity 1012 to the outer ring cavity 1011 or from the outer ring cavity 1011 to the inner ring cavity 1012 through the top surface of the liquid gathering ring 2, and will not overflow to the outside of the cooking cavity 101, effectively preventing the problem of overflowing the pot.

[0067] In this solution, when the height of the liquid gathering ring 2 in the vertical direction is less than the height of the cooking cavity 101 in the vertical direction, the top surface of the liquid gathering ring 2 is located on the inner side of the cooking cavity 101, that is, the top surface of the liquid gathering ring 2 is located below the top surface of the cookware 1, and the top surface of the liquid gathering ring 2 and the pot cover 5 placed on the cookware 1 are configured to be non-contacting with each other, that is, when the pot cover 5 is covered on the cookware 1, the pot cover 5 and the top surface of the liquid gathering ring 2 are in a non-contacting structure separated from each other, so that the top surface of the liquid gathering ring 2 and the pot cover 5 are not in contact with each other. A spacer 6 is formed in between, and the spacer 6 is formed into a structure that connects the outer ring cavity 1011 and the inner ring cavity 1012 for the flow of steam. When the pot cover 5 is closed on the cooker 1, the spacer 6 makes the outer ring cavity 1011 and the inner ring cavity 1012 form a connecting structure through the space area above the top surface of the liquid gathering ring 2, so that the boiled steam in the inner ring cavity 1012 enters the outer ring cavity 1011 or above the outer ring cavity 1011, preventing the heat in the inner ring cavity 1012 from being directly dissipated.

[0068] Optionally, in this embodiment, a steam outlet 501 is provided on the pot cover 5, and the steam outlet 501 is arranged to be located directly above the outer ring cavity 1011, so as to be neither located directly above the inner ring cavity 1012 nor located directly above the liquid gathering ring 2, so that the hot air or steam generated in the inner ring cavity 1012 during the heating process will be gathered in the inner ring cavity 1012 before entering into the outer ring cavity 1011 or above the outer ring cavity 1011 through the spacer 6 and then discharged to the outside through the steam outlet 501, which can effectively improve the concentration of heat in the inner ring cavity 1012, which is beneficial to increase the speed at which the liquid in the inner ring cavity 1012 is heated and boiled, and shorten the heating and boiling time.

[0069] In the present solution, in order to further enhance the speed at which the liquid in the inner annular cavity 1012 can be heated and boiled, thereby shortening the waiting time that the user needs to wait, a ratio Q2 of the total length formed by the second heating portion 4 and the volume formed by the inner annular cavity 1012 is set to be greater than a ratio Q1 of the total length formed by the first heating portion 3 and the volume formed by the outer annular cavity 1011; that is, the ratio Q2 is obtained by dividing the total length formed by the second heating portion 4 by the volume formed by the inner annular cavity 1012, and the ratio Q1 is obtained by dividing the total length formed by the first heating portion 3 by the volume formed by the outer annular cavity 1011, wherein, by setting the ratio Q2 to be greater than the ratio Q1, it is achieved that the length of the second heating portion 4 for providing heating for a unit volume of liquid or the same amount of liquid is greater than that of the first heating portion 3. 3 is used to provide heating length, thereby realizing that for a unit volume of liquid or the same amount of liquid, the total heat generated within the length range provided by the second heating part 4 is greater than the total heat generated within the length range provided by the first heating part 3, so that the total heat heated by the inner ring cavity 1012 is greater than the total heat heated by the outer ring cavity 1011, so that the liquid heated by the second heating part 4 can be heated and boiled faster, that is, the liquid in the inner ring cavity 1012 can be heated and boiled faster, so that the user can operate the hot pot through the inner ring cavity 1012 in a shorter waiting time, and the outer ring cavity 1011 can be further heated and boiled in a slower time to operate the hot pot.

[0070] Or, in the present solution, in order to further enhance the speed at which the liquid in the inner annular cavity 1012 can be heated and boiled, thereby shortening the waiting time that the user needs to wait, a ratio W2 of the total length formed by the second heating portion 4 to the area formed by the region B corresponding to the inner annular cavity 1012 on the inner bottom surface of the cookware 1 is set to be greater than a ratio W1 of the total length formed by the first heating portion 3 to the area formed by the region A corresponding to the outer annular cavity 1011 on the inner bottom surface of the cookware 1, that is, the ratio W2 is obtained by dividing the total length formed by the second heating portion 4 by the area formed by the region B corresponding to the inner annular cavity 1012 on the inner bottom surface of the cookware 1, and the ratio W1 is obtained by dividing the total length formed by the first heating portion 3 by the area formed by the region A corresponding to the outer annular cavity 1011 on the inner bottom surface of the cookware 1. The first heating portion 3 heats the region A, and the second heating portion 4 heats the region B. By setting the ratio W2 to be greater than the ratio W1, the effect of heating the cookware 1 on the heating of the cookware 1 is achieved. The length of the second heating part 4 for heating the liquid per unit area on the inner bottom surface of the pot 1 or the same amount of liquid is greater than the length of the first heating part 3 for heating, thereby achieving that the total heat generated within the length range of the second heating part 4 for heating the liquid per unit area on the inner bottom surface of the pot 1 or the same amount of liquid is greater than the total heat generated within the length range of the first heating part 3 to provide heating, so that the total heat heated by the inner ring cavity 1012 is greater than the total heat heated by the outer ring cavity 1011, so that the liquid heated by the second heating part 4 can be heated and boiled faster, that is, the liquid in the inner ring cavity 1012 can be heated and boiled faster, so that the user can operate the hot pot through the inner ring cavity 1012 in a shorter waiting time, and the outer ring cavity 1011 can be further heated and boiled at a slower time to operate the hot pot.

[0071] In the present solution, in order to further enhance the speed at which the liquid in the inner annular cavity 1012 can be heated and boiled, thereby shortening the waiting time required by the user, a ratio R2 of a total heating area formed by a projection area formed by the second heating portion 4 projecting upward on the cookware 1 in the vertical direction to a volume formed by the inner annular cavity 1012 is set to be greater than a ratio R1 of a total heating area formed by a projection area formed by the first heating portion 3 projecting upward on the cookware 1 in the vertical direction to a volume formed by the outer annular cavity 1011; that is, the ratio R2 is obtained by dividing the total heating area formed by the projection area formed by the second heating portion 4 projecting upward on the cookware 1 in the vertical direction by the volume formed by the inner annular cavity 1012, and the ratio R1 is obtained by dividing the total heating area formed by the projection area formed by the first heating portion 3 projecting upward on the cookware 1 in the vertical direction by the volume formed by the outer annular cavity 1011, wherein, by setting the ratio R2 to be greater than the ratio R1, the effect of The total heating area provided for heating by the second heating part 4 per unit area of ​​the inner bottom surface of the cookware 1 or the same amount of liquid is greater than the total heating area provided for heating by the first heating part 3, thereby achieving that the total heat generated within the total heating area range of the second heating part 4 for heating the liquid per unit area of ​​the inner bottom surface of the cookware 1 or the same amount of liquid is greater than the total heat generated within the total heating area range of the first heating part 3, so that the total heat heated by the inner ring cavity 1012 is greater than the total heat heated by the outer ring cavity 1011, so that the liquid heated by the second heating part 4 can be heated and boiled faster, that is, the liquid in the inner ring cavity 1012 can be heated and boiled faster, so that the user can operate the hot pot through the inner ring cavity 1012 in a shorter waiting time, and the outer ring cavity 1011 can be further heated and boiled at a slower time before operating the hot pot.

[0072] Alternatively, in the present solution, in order to further increase the speed at which the liquid in the inner annular cavity 1012 can be heated and boiled, thereby shortening the waiting time required by the user, it is provided that a ratio E2 of a total heating area formed by a projection area formed by the second heating portion 4 projecting upward on the cookware 1 in the vertical direction to an area B corresponding to the inner annular cavity 1012 on the inner bottom surface of the cookware 1 is greater than a ratio E2 of a total heating area formed by a projection area formed by the first heating portion 3 projecting upward on the cookware 1 in the vertical direction to an area B corresponding to the inner annular cavity 1011 on the inner bottom surface of the cookware 1 The ratio E1 of the areas formed by the corresponding areas A on the inner bottom surface of the cookware 1 is obtained by dividing the total heating area formed by the projection area formed by the second heating part 4 projecting upward on the cookware 1 in the vertical direction by the area B formed by the inner annular cavity 1012 corresponding to the inner bottom surface of the cookware 1 to obtain the ratio E2. The ratio E1 of the areas formed by the projection area formed by the first heating part 3 projecting upward on the cookware 1 in the vertical direction by the area A formed by the outer annular cavity 1011 corresponding to the inner bottom surface of the cookware 1 to obtain the ratio E2. Area B is heated, and area A is heated by the first heating part 3, wherein, by setting the ratio E2 to be greater than the ratio E1, it is achieved that the total heating area provided for heating by the second heating part 4 for the liquid per unit area on the inner bottom surface of the cookware 1 or the same amount of liquid is greater than the total heating area provided for heating by the first heating part 3, thereby achieving that the total heat generated within the total heating area range for heating by the second heating part 4 for the liquid per unit area on the inner bottom surface of the cookware 1 or the same amount of liquid is greater than the total heat generated within the total heating area range for heating by the first heating part 3, so that the total heat heated by the inner ring cavity 1012 is greater than the total heat heated by the outer ring cavity 1011, so that the liquid heated by the second heating part 4 can be heated and boiled faster, that is, the liquid in the inner ring cavity 1012 can be heated and boiled faster, so that the user can operate the hot pot through the inner ring cavity 1012 in a shorter waiting time, and the outer ring cavity 1011 can be further heated and boiled at a slower time to operate the hot pot.

[0073] Optionally, a passage can be provided on the liquid collecting ring 2, so that the outer ring cavity 1011 and the inner ring cavity 1012 are in a connected structure, so that when the user adds liquid into the cooking cavity 101, the liquid in the outer ring cavity 1011 and the liquid in the inner ring cavity 1012 will be maintained at the same liquid level, and the structure of the outer ring cavity 1011 and the inner ring cavity 1012 can form a structure in which the amount of liquid in the outer ring cavity 1011 is greater than the amount of liquid in the inner ring cavity 1012.

[0074] Of course, the outlet may not be provided, and the liquid collecting ring 2 has a certain height. When the liquid in the outer ring cavity 1011 and the liquid in the inner ring cavity 1012 both submerge the top surface of the liquid collecting ring 2, the liquid level in the outer ring cavity 1011 and the liquid level in the inner ring cavity 1012 are at the same liquid level height, and thus the structure of the outer ring cavity 1011 and the inner ring cavity 1012 can form a structure in which the amount of liquid in the outer ring cavity 1011 is greater than the amount of liquid in the inner ring cavity 1012.

[0075] Of course, the port may not be provided, and the user may independently add liquid to the outer ring cavity 1011 and the inner ring cavity 1012 respectively, and make the liquid in the outer ring cavity 1011 and the inner ring cavity 1012 remain at approximately the same liquid level height, so that the structure of the outer ring cavity 1011 and the inner ring cavity 1012 can form a liquid amount in the outer ring cavity 1011 that is greater than the liquid amount in the inner ring cavity 1012.

[0076] In this solution, the user can place liquid in the cooking cavity 101 and then install the liquid collecting ring 2 into the cooking cavity 101. At this time, the liquid collecting ring 2 divides the liquid in the cooking cavity 101 into two parts, one part of the liquid is located in the outer ring cavity 1011, and the other part of the liquid is located in the inner ring cavity 1012. At the same time, the liquid levels in the outer ring cavity 1011 and the liquid in the inner ring cavity 1012 are at the same liquid level height, and the amount of liquid in the inner ring cavity 1012 is less than the amount of liquid in the outer ring cavity 1011.

[0077] In the present solution, the structural arrangement of the outer annular cavity 1011 and the inner annular cavity 1012 enables the liquid in the inner annular cavity 1012 to be heated and boiled faster and in a shorter time. The area of ​​the region B corresponding to the inner annular cavity 1012 on the bottom surface of the cooker 1 is smaller, the volume of the inner annular cavity 1012 is smaller, and at the same time, the distance of the inner annular cavity 1012 in the radial direction and the length in the annular direction are smaller. In this way, the area and distance of heat transfer when the second heating part 4 heats the liquid in the inner annular cavity 1012 are also smaller, so that the heat generated by the second heating part 4 can be concentrated in the area of ​​the inner annular cavity 1012 for effective heating, so that the liquid in the inner annular cavity 1012 can be heated and boiled in a shorter time, while the liquid in the outer annular cavity 1011 will be heated and boiled more slowly. At this time, the user can use the inner annular cavity 1012 to make hot pot after a short waiting time, and the outer annular cavity 1011 can be used to put ingredients that need to be boiled for a longer time, so as to achieve the experience effect of making hot pot in different areas.

[0078] In the present solution, in order to enhance the speed at which the liquid in the inner annular cavity 1012 can be heated and boiled, the area formed by the second cross-sectional portion 401 of the second heating portion 4 can be larger than the area formed by the first cross-sectional portion 301 of the first heating portion 3; that is, the second cross-sectional portion 401 is formed on the cross-section of the second heating portion 4, and the first cross-sectional portion 301 is formed on the cross-section of the first heating portion 3, and the area of ​​the second cross-sectional portion 401 is larger than the area of ​​the first cross-sectional portion 301, that is, the area of ​​the cross-sectional area of ​​the second heating portion 4 is larger than the area of ​​the cross-sectional area of ​​the first heating portion 3, and the cross-sectional areas of the first heating portion 3 and the second heating portion 4 are mainly cross-sectional areas separated in the radial direction, so that the cross-sectional area formed by the second heating portion 4 for generating heat is larger than the cross-sectional area formed by the first heating portion 3 for generating heat, so that the second heating portion 4 can provide more heat to heat the liquid in the inner annular cavity 1012, so as to heat and boil the liquid in the inner annular cavity 1012 faster, thereby shortening the waiting time for users to eat hot pot.

[0079] In the present scheme, in order to enhance the speed at which the liquid in the inner annular cavity 1012 can be heated and boiled, the distance value formed by the second cross-sectional portion 401 of the second heating portion 4 in the radial direction can be greater than the distance value formed by the first cross-sectional portion 301 of the first heating portion 3 in the radial direction; that is, the second cross-sectional portion 401 is formed on the cross-section of the second heating portion 4, and the first cross-sectional portion 301 is formed on the cross-section of the first heating portion 3, and the distance value formed by the second cross-sectional portion 401 in the radial direction is greater than the distance value formed by the first cross-sectional portion 301 in the radial direction. The cross-sections of the first heating portion 3 and the second heating portion 4 are mainly cross-sections separated in the radial direction, so that the area corresponding to the distance value formed by the second heating portion 4 in the radial direction to generate heat is greater than the area corresponding to the distance value formed by the first heating portion 3 in the radial direction to generate heat, so that the second heating portion 4 can provide more heat to heat the liquid in the inner annular cavity 1012, so as to heat and boil the liquid in the inner annular cavity 1012 faster, thereby shortening the waiting time for users to have hot pot.

[0080] In the present solution, in order to increase the speed at which the liquid in the inner ring cavity 1012 can be heated and boiled, the power of the second heating part 4 can be set to be greater than or equal to the power of the first heating part 3 when heating, that is, the rated power or heating power of the second heating part 4 can be set to be greater than or equal to the rated power or heating power of the first heating part 3. Combined with the fact that the volume of the inner ring cavity 1012 is smaller than the volume of the outer ring cavity 1011, the liquid in the inner ring cavity 1012 can be heated and boiled in a shorter time than the liquid in the outer ring cavity 1011, so that the second heating part 4 can provide more heat to heat the liquid in the inner ring cavity 1012, so as to heat and boil the liquid in the inner ring cavity 1012 faster, thereby shortening the waiting time for users to have hot pot.

[0081] In the present solution, a limiting portion 102 can be provided on the bottom surface of the cooking cavity 101 for the installation structure of the liquid gathering ring 2. When the liquid gathering ring 2 is installed in place, the limiting portion 102 and the outer surface and / or inner surface of the liquid gathering ring 2 constitute a limiting structure that contacts each other. The limiting portion 102 is configured to be a recessed structure or a convex structure. For example, a groove of an annular structure is provided on the inner bottom surface of the cookware 1. When the liquid gathering ring 2 is installed in place, the bottom surface and a part of the inner surface and the outer surface of the liquid gathering ring 2 enter the groove to form a limiting structure in the radial direction to prevent the liquid gathering ring 2 from shifting. For example, two independent annular structure convex portions are provided on the inner bottom surface of the cookware 1, and the liquid gathering ring 2 is placed between the two convex portions to form a limited installation of the liquid gathering ring 2 to prevent the liquid gathering ring 2 from shifting in the radial direction. Both the installation and disassembly of the liquid gathering ring 2 can be realized, which is convenient for users to use and maintain the liquid gathering ring 2.

[0082] In the present solution, the installation structure of the liquid gathering ring 2 can also be provided with a magnetic attraction portion on the liquid gathering ring 2 to form a structure that is magnetically attracted to the cookware 1 through the magnetic attraction portion when the liquid gathering ring 2 is installed in place. The magnetic attraction portion can be set as a magnet made of magnetic material, and the cookware 1 is set as stainless steel. When the liquid gathering ring 2 is installed in place, it is magnetically attracted to the inner bottom surface of the cookware 1 through the magnetic attraction portion. The magnetic attraction structure makes it convenient for users to install the liquid gathering ring 2 in place or disassemble it for maintenance, thereby improving the effect of users using the liquid gathering ring 2.

[0083] In the present embodiment, the liquid gathering ring 2 is configured to have a hollow structure so that the inner and outer surfaces of the liquid gathering ring 2 do not contact each other in the radial direction. The hollow structure can realize a structure that isolates heat transfer. When the liquid in the inner ring cavity 1012 is rapidly heated, the heat in the inner ring cavity 1012 can be better prevented from being transferred to the outer ring cavity 1011 through the liquid gathering ring 2, so that the liquid gathering ring 2 forms a structure that isolates heat transfer. The heat in the inner ring cavity 1012 can be kept as much as possible in the inner ring cavity 1012 to heat the liquid in the inner ring cavity 1012, thereby increasing the speed at which the liquid in the inner ring cavity 1012 is heated.

[0084] Optionally, the hollow structure of the liquid collecting ring 2 is configured as a vacuum structure, which can achieve a better effect of isolating heat transfer.

[0085] In this solution, the cookware 1 can be configured as a detachable installation and placement structure, and an installation cavity is provided on the utensil body 10, in which the first heating part 3 and the second heating part 4 of this solution are installed. The cookware 1 can be installed in place by the user or disassembled for cleaning, which is convenient for the user to use and maintain the cookware 1.

[0086] The cooking utensil of the present solution may be an electric hot pot, an electric boiling pot, or an induction cooker; all of which may be configured according to the present solution so that the user can use the cooking utensil of the present solution to cook hot pot.

[0087] Anything not mentioned in this plan can be achieved by adopting or drawing on existing technologies.

[0088] Working principle: The cooking device of the present invention divides the cooking cavity 101 into an outer ring cavity 1011 located at the outer ring position of the cooking cavity 101 and an inner ring cavity 1012 located at the inner ring position of the cooking cavity 101 by means of the liquid collecting ring 2. The outer ring cavity 1011 and the inner ring cavity 1012 are respectively formed into two independent cavities to hold liquid, so that both the outer ring cavity 1011 and the inner ring cavity 1012 can be used to hold liquid to achieve the effect of hot pot; wherein, by limiting the volume of the inner ring cavity 1012 to be smaller than the volume of the outer ring cavity 1011, and limiting the position and structural setting of the second heating part 4, the second heating part 4 can better and faster heat the inner ring cavity The liquid in the inner ring cavity 1012 is heated. When the cooking appliance starts working, the liquid in the inner ring cavity 1012 can achieve a boiling effect faster than the liquid in the outer ring cavity 1011, thereby shortening the boiling speed of the liquid in the inner ring cavity 1012, so that the user does not need to wait too long to have hot pot through the inner ring cavity 1012. At this time, the outer ring cavity 1011 can be used to place some ingredients that need to be cooked for a longer time, and the inner ring cavity 1012 can be used for users to have real-time hot pot, and hot pot can be used for some ingredients that need to be cooked for a shorter time, thereby improving the user experience and greatly shortening the time users need to wait for hot pot.
