[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] In this solution, the liquid is heated by the first heating part of the heating element to generate steam, and the steam is reheated by the second heating part of the heating element, realizing a simple overall structure, low cost, and better steam heating effect.

[0027] In this solution, only a single heating element needs to be set, and the heating element is divided into two parts, one part is the first heating part and the other part is the second heating part. The effects of heating the liquid to generate steam and reheating the steam can be achieved through the two parts.

Detailed implementation manners

[0041] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0042] Embodiment: The steam cooking device of the present utility model, as Figures 1 to 6 shown in the composition, the steam cooking device is mainly used for steam cooking of food materials. The steam cooking device can be an electric steamer. Through the structural settings of this solution, a better reheating effect of the steam can be achieved, thereby greatly increasing the heating temperature of the steam and realizing a better steam cooking effect.

[0043] The steam cooking device of this solution includes a device main body 1, and the device main body 1 can be set to have a circular structure or a square structure. The device main body 1 is provided with a cooking pot 10, and the cooking pot 10 is correspondingly set to have a circular structure or a square structure, such as a circular pot or a square pot. The cooking pot 10 is provided with a cooking cavity 101, and the cooking cavity 101 is mainly used to hold liquid and generate steam when the liquid is heated. A heating element 20 with a convex structure facing upward is installed in the middle area of the bottom wall surface of the cooking cavity 101. The heating element 20 is installed on the bottom surface of the cooking cavity 101 with a convex structure facing upward. A part of the outer surface of the heating element 20 on the convex structure is used to heat the liquid, and a part is used to heat the steam, so that the structure of a single heating element 20 can not only heat the liquid to generate steam, but also reheat the generated steam, and the overall structure for reheating the steam is simple and low-cost.

[0044] Among them, for the specific structural part of the heating element 20, the heating element 20 is provided with a first heating part 201 and a second heating part 202. The first heating part 201 is a part of the heating element 20, and the second heating part 202 is also a part of the heating element 20. Specifically, the second heating part 202 is set to be located above the first heating part 201, and the first heating part 201 is located below the second heating part 202. When the cooking cavity 101 is filled with liquid, that is, when filled with clear water, at least a part of the first heating part 201 is located below the liquid level surface and at least a part of the second heating part 202 is located above the liquid level surface. A part or all of the first heating part 201 is located below the liquid level surface to form a structure submerged in the liquid. At this time, the first heating part 201 can form the effect of heating the liquid in contact to generate steam, while at least a part or all of the second heating part 202 is located above the liquid level surface to form not heating the liquid to generate steam, but to form reheating of the steam. That is, after the first heating part 201 heats the liquid to generate steam, the steam moves up and down through the liquid and enters above the first heating part 201. At this time, the steam will be heated by the second heating part 202 to form the effect of reheating the steam. After the steam is heated, the temperature of the steam can be increased and the humidity of the steam can be reduced. It can be seen that in this solution, only a single heating element 20 needs to be set, and the heating element 20 is divided into two parts, one part is the first heating part 201, and the other part is the second heating part 202. Through these two parts, the effects of heating the liquid to generate steam and reheating the steam can be achieved. The structure and distribution of the heating element 20 make the overall structure simple and low-cost.

[0045] Among them, the steam cooking device further includes a steam collecting member 30. The steam collecting member 30 is arranged to be located inside the cooking cavity 101 or above the cooking cavity 101 to form a shielding structure for most areas of the cooking cavity 101. The outer edge of the steam collecting member 30 can be arranged to be placed on the cooking pot 10 to form a structure above the cooking cavity 101, or the outer edge of the steam collecting member 30 can be arranged to be in contact with the side wall surface of the cooking cavity 101 to form a structure inside the cooking cavity 101, so as to realize the formation of a shielding structure of the steam collecting member 30 for most areas of the cooking cavity 101. The shielding structure can block the steam below the steam collecting member 30, and then realize the concentration of the steam below the steam collecting member 30. For the structural part for concentrating the steam, specifically, a steam collecting part 302 is provided on the steam collecting member 30. At least a part of the steam collecting part 302 is arranged to be located above the heating member 20, so as to realize that the steam can move from bottom to top and be concentrated near the lower position of the inner surface of the steam collecting part 302. At the same time, at least a part of the steam collecting part 302 is arranged such that the projection area formed by projecting downward in the vertical direction is configured to overlap at least partially with the first heating part 201 and / or the second heating part 202. The overlapping structure enables the steam generated by heating the liquid on the side surface of the first heating part 201 to directly enter the area near the lower position of the inner surface of the steam collecting part 302 upward. At this time, it can be set that the projection area formed by the steam collecting part 302 in the vertical direction can overlap with the side surface of the first heating part 201, or can overlap with the side surface of the second heating part 202, or can also overlap with both the side surface of the first heating part 201 and the side surface of the second heating part 202 at the same time. Under the above overlapping structure, the steam generated by heating the liquid by the first heating part 201 can move directly upward, and can directly enter the area near the lower position of the inner surface of the steam collecting part 302 in the vertical upward direction during the upward movement, forming a structure where the steam directly enters the lower inner area of the steam collecting part 302 for concentration. This can shorten the path for the steam to enter the lower inner area of the steam collecting part 302, improve the concentration effect of the steam entering the lower inner area of the steam collecting part 302, and further realize the effect of improving the re-heating of the steam by the second heating part 202 in the concentrated state.

[0046] Optionally, at least a part of the steam collecting part 302 is arranged such that the projection area formed by projecting downward in the vertical direction is configured to overlap at least partially with the first heating part 201 and the second heating part 202.

[0047] Preferably, a projection area formed by projecting at least a part of the steam collecting part 302 downward in the vertical direction is configured to completely overlap with the first heating part 201 and the second heating part 202. That is, a projection area formed by projecting at least a part of the steam collecting part 302 downward in the vertical direction can form an overlapping structure that covers all positions on the outer surface of the first heating part 201 and all positions on the outer surface of the second heating part 202. At this time, the steam can be better reheated and better enter the inner area below the steam collecting part 302 for concentration.

[0048] Among them, after the steam is concentrated and heated by the second heating part 202, the steam is discharged outward through the steam collecting part 302 to provide steam to the food material for the steam cooking function. Specifically, a steam outlet 3024 is provided on the steam collecting part 302. The steam outlet 3024 is set in a hole structure. The steam outlet 3024 penetrates the inner surface and the outer surface of the steam collecting part 302 to form a through-hole structure. The regional space position in the cooking cavity 101 below the steam collecting member 30 is configured to be in communication with the steam outlet 3024. In this way, the steam in the cooking cavity 101 can be blocked by the steam collecting member 30 and then move upward to enter the inner area below the steam collecting part 302. During this process, the steam is reheated by the second heating part 202 on the moving path. After the steam is heated, it will be discharged outward through the steam outlet 3024, providing steam with a higher temperature and lower humidity to the food material, thereby improving the steam cooking effect on the food material.

[0049] Optionally, the number of the steam outlets 3024 is set to be multiple. The multiple steam outlets 3024 are arranged in an annular spaced-apart structure or an annular radial spaced-apart structure on the steam collecting part 302, so that the steam can effectively enter the cooking space area of the cooking food material through the multiple steam outlets 3024. The cooking space area is located above the steam collecting member 30. The steam outlet 3024 is provided with an open structure facing directly upward or obliquely upward.

[0050] In this solution, a steam-blocking part 301 is provided on the steam-collecting part 30. The steam-blocking part 301 is configured to form a blocking structure for the cooking cavity 101, so that when the steam flows upward, it cannot pass through the steam-blocking part 301. The steam-blocking part 301 can block the steam generated in the cooking cavity 101 below the steam-collecting part 30, preventing the steam from moving upward through the steam-blocking part 301. As a result, the steam generated in the cooking cavity 101 can only move upward into the steam-collecting area 3021 and can only be discharged outward through the steam outlet 3024 on the steam-collecting part 30. Thus, it is realized that the steam will be concentrated in the steam-collecting area 3021 before being discharged outward through the steam outlet 3024. Among them, the steam-collecting part 302 is arranged in the inner area of the steam-blocking part 301, that is, the steam-collecting part 302 is arranged at the inner ring position of the steam-collecting part 30, and the steam-blocking part 301 is arranged at the outer ring position of the steam-collecting part 30. The steam-blocking part 301 forms a structure that annularly surrounds the steam-collecting part 302 in its inner area. And the steam-collecting part 302 is configured to be a convex structure relative to the steam-blocking part 301 to form a steam-collecting area 3021. The steam-collecting area 3021 is a concave structure for accumulating steam. The steam-collecting part 302 is configured to be an upward convex structure relative to the steam-blocking part 301. The upward convex structure causes a concave structure to be formed at the inner position below the steam-collecting part 302, and this concave structure forms the steam-collecting area 3021. Thus, the effect of the steam-collecting area 3021 for accumulating steam is realized. With the combination of the steam-blocking part 301 and the steam-collecting part 302, it is realized that the steam will be concentrated and enter the steam-collecting area 3021.

[0051] Optionally, the heating part 20 is configured to be an annular structure, which can be a circular convex structure.

[0052] Optionally, the heating part 20 can be configured to be an annular cylindrical structure, such as a cylindrical structure.

[0053] Optionally, the heating part 20 can be configured to be an annular conical structure, such as a conical structure.

[0054] Optionally, the cooking cavity 101 is configured to be a circular ring structure or a square annular structure, and the steam-blocking part 301 is correspondingly configured to be a circular ring structure or a square annular structure.

[0055] Regarding the structural part of the steam collecting section 302, the steam collecting section 302 is arranged to form an occlusion structure for the top surface of the second heating section 202, so that the top surface of the second heating section 202 is located below the inner top surface of the steam collecting section 302. The occlusion structure forms a blocking structure for the upward movement of steam, and is configured to form an annular surrounding structure for a part of the side surface of the second heating section 202. Mainly, the steam collecting section 302 is arranged to be in an annular structure to form an annular surrounding structure for the second heating section 202, that is, to form an annular surrounding structure for the annular side surface of the second heating section 202. The annular surrounding structure can better accumulate steam, so that the steam forms a surrounding structure in the outer area of the side surface of the second heating section 202, and is configured to form a steam collecting area 3021 between the outer surface of the second heating section 202 and the inner surface of the steam collecting section 302 to form a structure for concentrating steam in the steam collecting area 3021. The space area formed between the outer surface of the second heating section 202 and the inner surface of the steam collecting section 302 is configured to be the steam collecting area 3021. The steam collecting area 3021 with a concave structure forms an annular concave structure for concentrating steam. When the steam is concentrated in the steam collecting area 3021, it also forms a concentration in the outer area of the side surface of the second heating section 202 to better contact the side surface of the second heating section 202 and be heated.

[0056] Optionally, the steam collecting section 302 is arranged to be in an annular structure, that is, an annular convex structure.

[0057] Optionally, the steam collecting area 3021 is arranged to be in an annular structure, configured to be an annular concave structure for accumulating steam, and form an annular surrounding effect for a part of the side surface of the second heating section 202.

[0058] In this solution, in order to better achieve the accumulation of steam in the steam collection area 3021, the horizontal plane where the central position of the height distance of the second heating part 202 in the vertical direction is set as M. The part of the second heating part 202 above the horizontal plane M is located inside the steam collection part 302, so as to form a structure in which the steam collection part 302 annularly wraps the part of the second heating part 202 above the horizontal plane M. That is, the part of the second heating part 202 above the horizontal plane M is in a structure surrounded by the steam collection part 302 in a ring shape. Under the annular wrapping structure, a spatial area in a ring shape is formed between the inner surface of the steam collection part 302 and the inner surface of the part of the second heating part 202 above the horizontal plane M. This spatial area constitutes a part of the steam collection area 3021. And the annular wrapping structure can achieve the annular wrapping of the steam in the outer area of the side surface of the second heating part 202, that is, in the inner area of the inner surface of the steam collection area 3021, so as to achieve the effect of centralized accumulation and annular wrapping of the steam, which is beneficial to the effective accumulation of the steam and then the steam is reheated by the second heating part 202. It not only realizes the effect of steam accumulation in the steam collection area 3021, but also realizes the heating effect that the steam can be effectively contacted by the second heating part 202 over a large area.

[0059] In order to better guide the steam into the steam collection area 3021 for concentration, in this solution, a guiding part 3022 is provided on the steam collection part 302. A guiding channel 3023 is formed between the inner surface of the guiding part 3022 and the side surface of the second heating part 202. The guiding channel 3023 is used for the flow of steam. The guiding channel 3023 is set as a vertically upward channel structure or a slanting channel structure that is inclined upward above the central axis N of the heating part 20 in the vertical direction, so as to form a structure for guiding the steam to move towards the side surface of the second heating part 202. The structure of the guiding channel 3023 can form a structure for guiding the steam to flow through it, and then guide the steam to move in the channel direction of the guiding channel 3023, which can better guide the steam into the steam collection area 3021, can better guide the steam to the side surface of the second heating part 202, realize the better centralized accumulation of the steam, and realize the better reheating of the steam.

[0060] Among them, when the guiding channel 3023 is set as a vertically upward channel structure, at this time, the guiding channel 3023 is a straight up-and-down channel structure, which can better form a structure for guiding the steam to move directly upward.

[0061] Among them, when the guiding channel 3023 is set to an inclined channel structure that is inclined above the central axis N of the heating element 20 in the vertical direction, the guiding passage can better guide the steam to move along the inclined direction to the side surface of the second heating part 202, so as to better reheat the steam.

[0062] Optionally, the inner side surface of the guiding part 3022 is set to an inclined structure, mainly set to be inclined above the second heating part 202 to form a structure for guiding the steam to move along the inclined direction, so that the steam can better move into the steam collecting area 3021 for concentration, and be centrally heated by the second heating part 202 during the concentration process.

[0063] Optionally, the steam outlet 3024 is set on the guiding part 3022, so that the steam can be better concentrated in the steam collecting area 3021, reheated by the second heating part 202, and then discharged outwards through the steam outlet 3024, thereby improving the effect of reheating the steam.

[0064] Optionally, the steam outlet 3024 can be set on the inner top surface of the steam collecting part 302 to form a through structure, that is, the steam outlet 3024 penetrates the inner top surface and the outer top surface of the steam collecting part 302 to connect the steam collecting area 3021 with the external space of the steam collecting part 30. It can also form a structure in which the steam can be better concentrated in the steam collecting area 3021, reheated by the second heating part 202, and then discharged outwards through the steam outlet 3024, thereby improving the effect of reheating the steam.

[0065] In this solution, the steam collecting part 302 can correspond to the annular structure of the heating element 20 and is correspondingly set to an annular structure. The steam collecting area 3021 on the steam collecting part 302 is set to an annular concave structure, and the guiding part 3022 on the steam collecting part 302 is correspondingly also set to an annular structure, so that the formed guiding channel 3023 is also set to an annular structure in the annular direction, thereby forming an annular guiding channel 3023 with a channel structure in the up and down directions. The lower end of the guiding channel 3023 is connected to the space area below the steam collecting part 30 in the cooking cavity 101 for steam to enter the guiding channel 3023. The lower end of the guiding channel 3023 constitutes a part of the steam collecting area 3021 to form steam entering the steam collecting area 3021. The steam is reheated by the second heating part 202 and then enters the steam collecting area 3021 for concentration and accumulation, and then the heated steam is centrally discharged upwards through the steam outlet 3024, so as to achieve a better steam cooking effect on the food materials. Because the temperature of the steam is higher and the humidity is lower after being reheated, the cooking time of the food materials can be increased, the steam cooking time of the food materials can be shortened, and the steam cooking taste of the food materials is better.

[0066] In order to further improve the effect of steam generation and the effect that the steam can be better reheated by the second heating part 202, in this solution, it is set that the area for contacting the liquid for heating formed by the first heating part 201 in the circumferential direction is larger than the area for contacting the steam for heating formed by the second heating part 202 in the circumferential direction. By setting that the first heating part 201 has a larger area in the circumferential direction for contacting the liquid for heating, more steam can be generated in the circumferential direction. At the same time, the steam can be better separated and move upward in the circumferential direction. At the same time, by setting that the second heating part 202 has a smaller heating area in the circumferential direction, it is beneficial for the steam to move more easily into the steam collecting area 3021 during the upward movement, and at the same time, it can move better along the outer side surface of the second heating part 202 in the vertical direction. It is also beneficial for the steam to be better concentrated and move concentratedly into the steam collecting area 3021 along the circumferential direction of the second heating part 202, so as to achieve the effect of improving the steam generation effect and the effect that the steam can be better reheated by the second heating part 202.

[0067] And / or, in order to further improve the effect that the steam can be better reheated by the second heating part 202, in this solution, it is set that the height distance H1 for contacting the liquid for heating formed by the first heating part 201 in the vertical direction is less than the height distance H2 for contacting the steam for heating formed by the second heating part 202 in the vertical direction. By setting that the height distance of the first heating part 201 in the vertical direction is relatively lower, the steam can quickly enter the vicinity of the side surface position of the second heating part 202 upward. At the same time, by setting that the second heating part 202 has a relatively higher height distance in the vertical direction, a relatively higher height distance is formed on the side surface of the second heating part 202 in the vertical direction, so as to form a longer path for reheating the steam on the path of the steam moving upward. It can be realized that the second heating part 202 has a larger heating area to effectively reheat the moving steam, and further improve the effect that the steam can be better reheated by the second heating part 202.

[0068] In order to further improve the concentration effect of steam entering the steam collection area 3021, in this solution, the projection area formed by the steam collection part 302 projecting downward in the vertical direction is configured to cover the first heating part 201 and a part of the bottom wall surface of the cooking cavity 101, so that the steam generated by heating the liquid on the side surface of the first heating part 201 can directly enter the steam collection area 3021 upward; at this time, the projection area formed by the steam collection part 302 in the vertical direction can comprehensively cover the side surface position of the first heating part 201, and at the same time form a covering structure for the position where the first heating part 201 meets the inner bottom surface of the cooking cavity 101 and the area near the meeting position. Under this covering structure, the steam generated by heating the liquid by the first heating part 201 can directly move upward, and directly enter the steam collection area 3021 vertically upward during the upward movement process, forming an effect that the steam directly enters the steam collection area 3021, shortening the path of the steam entering the steam collection area 3021, improving the concentration effect of the steam entering the steam collection area 3021, and further realizing the effect of improving the re - heating of the steam by the second heating part 202 in the steam collection area 3021.

[0069] In this solution, for the structural part of the steam blocking part 301, the steam collection part 30 is mainly set as a detachable installation structure. It can be that the outer edge position of the steam blocking part 301 is set to be placed on the cooking pot 10 or the outer edge position of the steam blocking part 301 is set to be in contact with the side wall surface of the cooking cavity 101, so as to form a structure in which the steam blocking part 301 blocks most of the area of the cooking cavity 101. The steam blocking part 301 is located below the top surface of the second heating part 202 and above the first heating part 201, so that the steam blocking part 301 can effectively form a blocking structure for the steam in the cooking cavity 101 below the second heating part 202 and guide the steam to enter the steam collection area 3021. When the steam moves upward and is blocked by the steam blocking part 301, it forms a structure in which the steam moves along the lower surface of the steam blocking part 301 towards the steam collection area 3021 direction, realizing that the steam enters the steam collection area 3021 under the blocking structure of the steam blocking part 301 and is reheated by the side surface of the second heating part 202, thereby improving the smoothness of the steam moving towards the steam collection area 3021 and the effect of the steam being reheated by the second heating part 202.

[0070] Among them, when the outer edge position of the steam blocking part 301 is set to be placed on the cooking pot 10, it is mainly set to be directly limited and placed on the top end face position of the cooking pot 10, so as to form that the steam collection part 30 is detachably placed on the cooking pot 10 through the steam blocking part 301, which is convenient for users to install the steam collection part 30 in place or perform disassembly and maintenance.

[0071] Among them, when the outer edge position of the steam blocking part 301 is set to be in contact with the side wall surface of the cooking cavity 101, the main structure is that the outer side surface of the outer edge position of the steam blocking part 301 forms a contact and fitting structure with the side wall surface of the cooking cavity 101, and at the same time forms a certain deformation extrusion structure. At this time, a sealing member with a flexible structure can be installed on the outer side surface of the outer edge position of the steam blocking part 301. The sealing member is in contact and fitting with the side wall surface of the cooking cavity 101 to form a squeezing force and a frictional force, so as to realize that the steam collecting member 30 is placed in the cooking cavity 101, which is convenient for the user to install or disassemble and maintain the steam collecting member 30 in place.

[0072] Among them, a support part with a convex structure can also be provided on the four side wall surfaces of the cooking cavity 101 and oriented towards the middle area of the cooking cavity 101. The support part forms a structure for placing the steam collecting member 30 to realize a support and limit structure for the steam collecting member 30 in the vertical direction.

[0073] In this solution, for the liquid in the cooking cavity 101, mainly the user manually adds liquid, that is, clear water, into the cooking cavity 101. Regarding the setting of the height position of the liquid level surface of the liquid in the cooking cavity 101, mainly a liquid level display part 1011 is provided on the side wall position of the cooking cavity 101. The liquid level display part 1011 is used to play a role of marking and guiding for the clear water manually added by the user, that is, it plays the role of a scale line. The user can add clear water into the cooking cavity 101 until the liquid level surface of the clear water reaches the liquid level display part 1011 or above the liquid level display part 1011. At this time, the liquid in the cooking cavity 101 forms an immersion structure with respect to the liquid level display part 1011, and then the steam cooking device can be controlled to start working to execute the steam cooking function. The height distance from the liquid level display part 1011 down to the bottom wall surface of the cooking cavity 101 is greater than or equal to the height distance of the first heating part 201. In this way, when the user adds clear water into the cooking cavity 101 according to the height of the liquid level display part 1011, the height distance of the liquid level surface of the clear water in the cooking cavity 101 will always be greater than or equal to the height distance of the first heating part 201, thereby effectively forming an immersion structure with respect to the side surface of the first heating part 201. The side surface of the first heating part 201 can effectively contact the liquid to heat and generate steam, realizing stable steam generation in the cooking cavity 101, and effectively ensuring that the entire part of the first heating part 201 is located below the liquid level surface of the liquid to stably heat the liquid and generate steam.

[0074] Wherein, when the liquid level display part 1011 is located above the first heating part 201, the height distance H0 from the liquid level display part 1011 upward to the top surface of the second heating part 202 is set to be greater than or equal to two-thirds of the height distance of the second heating part 202. At this time, when the user follows the height of the liquid level display part 1011 to add clear water to the cooking cavity 101, the height distance of the liquid level surface of the clear water in the cooking cavity 101 will make the first heating part 201 located below the liquid level surface, and a small part of the height distance of the second heating part 202 in the vertical direction can be located below the liquid level surface. By setting the height distance H0 from the liquid level display part 1011 upward to the top surface of the second heating part 202 to be greater than or equal to two-thirds of the height distance of the second heating part 202, it is ensured that more than two-thirds of the second heating part 202 in the vertical direction will not be submerged by the liquid level, and most of the side surface of the second heating part 202 can be located above the liquid level surface and exposed to reheat the steam, thereby ensuring that the steam can be effectively reheated by the second heating part 202 and achieving the effect of improving the reheating of the steam.

[0075] In order to better guide the steam to move into the steam collecting area 3021 for centralized heating by the second heating part 202, and thus achieve the effect of reheating the steam, in this solution, the side surfaces of the first heating part 201 and / or the second heating part 202 are set to be inclined upward toward the central axis N of the heating element 20 in the vertical direction to form a structure for guiding the steam to move in the direction of the side surface of the second heating part 202 and the steam collecting area 3021. The inclined structure will form a guide for the steam to move along the inclined direction. Under the guidance of the inclined structure, the steam will move toward the side surface of the second heating part 202 to be heated, and at the same time, the steam will also converge into the steam collecting area 3021 and gather in the steam collecting area 3021, so that the steam can be effectively in contact with the second heating part 202 in the steam collecting area 3021 for heating, thereby improving the effect of reheating the steam.

[0076] Preferably, the side surfaces of both the first heating part 201 and the second heating part 202 are set to be inclined upward toward the central axis N of the heating element 20 in the vertical direction, so as to better guide the steam to be reheated.

[0077] Preferably, the side surfaces of the first heating part 201 and the second heating part 202 are both arranged to be inclined upward toward the central axis N of the heating element 20 in the vertical direction, and the side surfaces of the first heating part 201 and the second heating part 202 form a continuous inclined surface structure in the inclined direction. In this way, it is possible to better guide the steam to move along the inclined surface structure to the side surface of the second heating part 202 for heating, achieving the effect of enhancing the re-heating of the steam.

[0078] Alternatively, in order to better guide the steam to move into the steam collecting area 3021 for centralized heating by the second heating part 202, thereby achieving the effect of re-heating the steam, in this solution, the first heating part 201 and the second heating part 202 are arranged to be an integral structure, so that the heating element 20 has an integral structure, and the heating element 20 is arranged to have an outer diameter value that gradually decreases in the circumferential direction from bottom to top. The integral structure makes the overall structure of the heating element 20 simpler, and the installation and manufacturing costs of the heating element 20 are lower. At the same time, the integral structure can also form a side surface of the first heating part 201 and a side surface of the second heating part 202 into an integrally continuous surface structure, thereby achieving a better guiding effect on the steam, which is beneficial for the steam to be effectively guided into the steam collecting area 3021 for concentration and then re-heated by the second heating part 202. Moreover, the heating element 20 is arranged to have an outer diameter value that gradually decreases in the circumferential direction from bottom to top, so that the heating element 20 has an overall convex conical structure, realizing that the side surfaces of the first heating part 201 and the second heating part 202 are inclined in the up-down direction, mainly forming a structure inclined upward toward the central axis N of the heating element 20 in the vertical direction. The inclined structure will cause the steam to move along the inclined direction. Under the guidance of the inclined structure, the steam will move toward the side surface of the second heating part 202 for heating, and at the same time, the steam will also converge and concentrate toward the steam collecting area 3021 and then gather in the steam collecting area 3021, so that the steam can effectively contact the second heating part 202 in the steam collecting area 3021 for heating, thereby enhancing the effect of re-heating the steam.

[0079] Alternatively, in order to better concentrate the steam in the vicinity of the side surface of the second heating unit 202, and to better guide the steam to be timely supplied to the outside for cooking the food ingredients after being reheated, in this solution, the height distance H3 from the top surface of the second heating unit 202 to the inner top surface of the steam collecting unit 302 is set to be less than the interval distance L1 from the side surface of the second heating unit 202 to the inner side surface of the steam collecting unit 302, so as to form a structure in which the steam moves towards the steam outlet 3024 under the shielding structure of the steam collecting unit 302. In this way, the steam will be blocked by the inner top surface of the steam collecting unit 302 during the upward movement and move towards the outer side in the horizontal direction and the lower side in the vertical direction. Since the height distance H3 from the top surface of the second heating unit 202 to the inner top surface of the steam collecting unit 302 is relatively smaller, the formed space area is smaller, and thus more steam will be concentrated in the vicinity of the outer side of the side surface of the second heating unit 202, so as to effectively reheat the steam by the second heating unit 202. At the same time, the steam will move towards the direction of the steam outlet 3024 under the shielding structure of the steam collecting unit 302, and thus more steam will enter the steam outlet 3024 more smoothly after being reheated and be discharged to the outside, so as to improve the smoothness of the steam movement and better guide the steam to be timely supplied to the outside for cooking the food ingredients after being reheated.

[0080] Optionally, the steam outlet 3024 is arranged at the side position of the steam collecting unit 302 to penetrate through the inner side surface and the outer side surface of the steam collecting unit 302, so as to effectively discharge the steam.

[0081] In addition to the equipment main body 1, the steam cooking equipment of this solution further includes a steaming grid and a steaming tray. The steaming grid and the steaming tray can be an integral overall structure or a split structure. The steaming grid is placed on the equipment main body 1 or on the cooking pot 10 above the steam collecting member 30. A plurality of steam ports are arranged on the steaming grid, and the steaming grid is used to hold food ingredients. The steam discharged through the steam collecting member 30 can enter above the steaming grid through the steam ports to perform steam cooking on the food ingredients. The steaming tray can be placed on the steaming grid to form a surrounding internal space to surround the food ingredients and form a steam cooking space. The food ingredients are placed on the steaming grid and within the steam cooking space. The steam enters the steam cooking space after being discharged through the steam collecting member 30 to achieve the steam cooking effect on the food ingredients. Among them, a plurality of steaming grids and steaming trays can be provided to form a group with a single steaming grid and a single steaming tray. The steaming grid and the steaming tray in a single group form a single-layer steam cooking space. A plurality of groups can be stacked up and down to form a multi-layer steam cooking space to hold more food ingredients for steam cooking in multiple layers. Of course, a pot lid can also be provided at the top to cover the steam cooking space. The pot lid can be placed on the steaming tray to form a shielding structure, thereby realizing the steam cooking function of the steam cooking equipment.

[0082] Optionally, an exhaust port is provided on the pot lid to discharge the steam in the steam cooking space, preventing the air pressure in the steam cooking space from becoming too high.

[0083] The steam cooking device of this solution can be set as an electric steamer.

[0084] What is not described in this solution can be implemented by adopting or referring to the prior art.

[0085] Working principle: In this solution, the cooking cavity 101 is mainly used to hold liquid, that is, clear water, which generates steam when heated. At the same time, during the generation of steam, the steam is reheated to increase the temperature of the steam and reduce the humidity of the steam. Specifically, after the liquid in the cooking cavity 101 is heated by contact with the first heating part 201 of the heating element 20 to generate steam, the steam is guided by the steam collecting element 30 so that the steam is heated by contact with the second heating part 202. The overall structure for reheating the steam set in this solution is simple and low-cost. By making full use of the flow of steam, the steam collecting element 30 is set to gather the steam, and the gathered steam is reheated, achieving a better effect and a simpler structure for reheating the steam. At the same time, the generated steam will also be concentrated in the steam collecting area 3021 and discharged outward in a concentrated manner. The concentrated steam will be discharged outward through the steam outlet 3024, mainly to provide the steam heated to the ingredients above the equipment main body 1. Because the temperature of the steam is higher and the humidity is lower, a better steam cooking effect on the ingredients can be achieved, and at the same time, the time for the ingredients to be cooked and prepared can be shortened, thereby greatly improving the user experience effect.

In actual applications, various changes can be made in form and details without departing from the spirit and scope of the present utility model, and all are within the protection scope of the present utility model.
