[0048] Embodiment 1

[0049] like Figure 1 and Figure 2 As shown, this embodiment provides a cooking device, which can steam and cook food in a cooking cavity 111 by introducing hot steam into an inner pot 11, improve the uniformity of steam inlet in the cooking cavity 111, and facilitate anaerobic or low-oxygen cooking of the cooking device, thereby improving the user experience of the cooking device. The cooking device may be a steamer, a steam-bake-in-one machine, or a microwave steam-bake-in-one machine.

[0050] Specifically, the cooking device includes a machine body, an inner pot assembly 10, a machine door, a steam generating assembly 20 and a control device 40. The machine body includes a machine frame 50 and a shell arranged outside the machine frame 50, the inner pot assembly 10 is arranged inside the machine body and has a cooking cavity 111 with a front opening, the machine door is arranged at the front side of the shell and can selectively open or close the front opening of the cooking cavity 111; the steam generating assembly 20 is used to supply steam to the cooking cavity 111; the control device 40 is connected to the steam generating assembly 20 in communication to control the operation of the steam generating assembly 20.

[0051] In this embodiment, the inner pot assembly 10 includes a cooking cavity 1 and a diverter 2. The cooking cavity 1 has a cooking cavity 111, and steam cavities 124 are arranged on the upper parts of the left and right sides of the cooking cavity 111. The steam cavity 124 is a long strip structure extending in the front-to-back direction. Each steam cavity 124 is connected to the cooking cavity 111 through a plurality of steam through holes 1121. The plurality of steam through holes 1121 are arranged at intervals in the front-to-back direction. A steam inlet 125 is provided on the cavity wall of the steam cavity 124, and an exhaust port is provided at the lower part of the cooking cavity 111. The diverter 2 is arranged in the steam cavity 124, and the diverter 2 is used to rectify the steam in the steam cavity 124. The diverter 2 is used to rectify the steam in the steam cavity 124 in the front-to-back direction so that the steam amount flowing out of all the steam through holes 1121 on the same side tends to be consistent.

[0052] Before cooking begins, the steam generating assembly 20 generates hot steam and passes the hot steam into the steam chambers 124 on both sides of the cooking chamber 111 through the steam inlet 125, and the steam in the steam chamber 124 flows into the cooking chamber 1 through the steam through hole 1121. Since the density of the hot steam is greater than the density of the cold air in the cooking chamber 111, the hot steam entering the cooking chamber 111 forms a steam layer at the upper part of the cooking chamber 111, and when the hot steam continuously flows into the cooking chamber 111, the steam layer expands downward and squeezes the air in the cooking chamber 111 downward, so that the air is squeezed out of the cooking chamber 111 through the exhaust port until the hot steam fills the cooking chamber 111.

[0053] That is, the inner pot assembly 10 and the cooking device provided in the present embodiment are provided with steam chambers 124 connected to the cooking chamber 111 at the upper parts of the left and right sides of the cooking chamber 111, and an exhaust port is provided at the lower part of the cooking chamber 111. Since the density of hot steam is smaller than that of the cold air in the cooking chamber 111, the hot steam entering the cooking chamber 111 can form a hot steam layer at the top of the cooking chamber 111. When the hot steam layer expands downward, it squeezes the air from top to bottom, so that the oxygen-containing air is discharged to the outside of the cooking chamber 111 through the exhaust port, thereby realizing anaerobic or low-oxygen cooking of the cooking device, and at the same time reducing the amount of mixing of air and hot steam during the air discharge process, thereby reducing the discharge amount of hot steam, improving the discharge speed and discharge effect of oxygen-containing air, and reducing energy consumption; by arranging the steam chambers 124 at the left and right sides of the cooking chamber 111, it is possible to realize the spray-type steam inlet on both sides of the cooking chamber 111, so that the steam can quickly irrigate the cooking chamber 111 The upper space is filled, which is more conducive to the rapid oxygen and air exhaust of the cooking cavity 111; at the same time, since the steam cavity 124 is set as a long strip structure extending in the front-to-back direction, and a diverter 2 is set in the steam cavity 124, when the steam enters the cooking cavity 111 from the steam cavity 124, the steam intake of the cooking cavity 111 is relatively uniform in the front-to-back direction, so that the hot steam entering the cooking cavity 111 can quickly fill various places on the top of the cooking cavity 111, and improve the uniformity of the hot steam layer in various places in the horizontal direction, thereby further reducing the mixing amount of steam and air during the air discharge process, and further improving the discharge efficiency and discharge effect of oxygen-containing air; further, since the air intake uniformity of steam from the steam cavity 124 to the cooking cavity 111 is increased, during the cooking process, the steam uniformity of various places in the cooking cavity 111 can be improved, and the temperature consistency of various places in the cooking cavity 111 can also be better guaranteed, thereby improving the effect of food cooking.

[0054] In this embodiment, the depth of the steam cavity 124 along the front-to-back direction is L0, the width of the steam cavity 124 along the front-to-back direction is L1, and L0>L1≥0.7L0, thereby increasing the effective range of the steam cavity 124 in the front-to-back direction, improving the uniformity of steam intake in the front-to-back direction of the cooking cavity 111, and making it more conducive for hot steam to quickly fill the top space of the cooking cavity 111. More preferably, L1≥0.8L0.

[0055] The height of the cooking cavity 111 in the vertical direction is H, and the distance between the upper end of the steam cavity 124 and the top wall of the cooking cavity 111 is d1, 0<d1≤0.25H, so that the steam cavity 124 can be closer to the top of the cooking cavity 111, so that the top space of the cooking cavity 111 can be filled first, and the steam layer in the cooking cavity 111 can expand from top to bottom, reducing the amount of mixing of air and steam, thereby reducing the steam cavity 124 discharged during the exhaust process.

[0056] In this embodiment, the distance between the exhaust port and the top of the cooking cavity 111 is d2, H>d2≥0.8H, so that the exhaust port is arranged as close as possible to the bottom of the cooking cavity 111, so as to better promote the discharge of air at the bottom of the cooking cavity 111, and to facilitate the rapid exhaust of oxygen-containing air and improve the exhaust efficiency. In this embodiment, the exhaust port is arranged on the rear wall of the cooking cavity 111, and in other embodiments, the exhaust port can be arranged on the left and right side walls of the cooking cavity 111.

[0057] The cooking cavity 111 has a second symmetry plane perpendicular to the left-right direction, the steam cavities 124 on both sides are symmetrically arranged relative to the second symmetry plane, and the steam holes 1121 on both sides are symmetrically arranged relative to the second symmetry plane, thereby making the steam inlet settings on both sides of the cooking cavity 111 more consistent, and better ensuring the uniformity of steam entering from the steam holes 1121 on the left and right sides.

[0058] The cooking cavity 1 comprises an inner pot 11 and a steam hood 12 arranged outside the inner pot 11, the inner wall of the inner pot 11 encloses a cooking cavity 111, the steam hood 12 and the outer wall of the inner pot 11 enclose a steam cavity 124, steam holes 1121 are provided on the left and right side walls of the inner pot 11, the steam hood 12 is detachably connected to the inner pot 11, and the flow divider 2 is installed on the steam hood 12. This arrangement is conducive to simplifying the processing of the inner pot 11 and the steam hood 12, and at the same time, because the connection position of the steam hood 12 and the inner pot 11 is located outside the inner pot 11, the connection between the steam hood 12 and the inner pot 11 will not form a gap located inside the cooking cavity 111, which is conducive to setting a microwave cooking function in the cooking device.

[0059] In other embodiments, the inner liner 11 and the steam cover 12 can also be integrally formed, that is, an opening of the steam chamber 124 is formed on the inner wall of the inner liner 11, and a steam outlet plate is installed at the opening of the steam chamber 124 of the inner liner 11, and a steam through hole 1121 is opened on the steam outlet plate.

[0060] like Figures 3 to 6As shown, in order to improve the diversion effect of the diverter 2, the diverter 2 is divided into a plurality of steam diverter channels 21, and the diverter steam inlets of the plurality of steam diverter channels 21 are all connected to the steam inlet 125, and the diverter steam outlets of the plurality of steam diverter channels 21 are arranged in sequence in the front-to-back direction, and the diverter steam outlets are connected to the steam through hole 1121. The steam entering the steam inlet 125 is rectified in the front-to-back direction by the steam diverter channel 21 for the steam flowing out of the diverter steam outlet. This arrangement enables the steam entering the steam chamber 124 from the steam inlet 125 to be diverted into the plurality of steam diverter channels 21 through the diverter steam inlets of the plurality of steam diverter channels 21. Since the diverter steam outlets of the plurality of steam diverter channels 21 are arranged in sequence in the front-to-back direction, the steam is guided to different positions in the front-to-back direction through the steam diverter channel 21 for steam discharge, thereby ensuring that the steam flowing out of each steam diverter channel 21 can cover the entire steam chamber 124 in the front-to-back direction.

[0061] The steam chamber 124 includes a first chamber 1241 and a second chamber 1242 which are arranged side by side and connected to each other. The steam inlet 125 is arranged in the first chamber 1241 and the diverter 2 is arranged in the first chamber 1241. The steam through hole 1121 is arranged opposite to the second chamber 1242. The diverter 2 rectifies the steam entering the second chamber 1242 from the first chamber 1241 in the front-to-back direction.

[0062] According to the above arrangement, the diverter 2 rectifies the steam entering the second chamber 1242 from the first chamber 1241, so that the steam in the second chamber 1242 can be more uniform in the front-to-back direction, thereby making the steam flowing out of the steam through hole 1121 from the second chamber 1242 more uniform in the front-to-back direction; and by setting up the first chamber 1241, the steam entering the second chamber 1242 from the first chamber 1241 is rectified once through the diverter 2, and the steam flowing out of the first chamber 1241 from the second chamber 1242 can be rectified twice, which can prevent the unrectified steam from directly flowing out through the steam through hole 1121, thereby improving the steam rectification effect.

[0063] That is, in this embodiment, the steam outlet of each steam diverter channel 21 is open upward or downward, so that the steam flows from the first chamber 1241 to the second chamber 1242. In other embodiments, the steam chamber 124 may not be provided with the first chamber 1241 and the second chamber 1242, and the steam outlet of each steam diverter channel 21 may also be open toward the cooking chamber 111, and the steam flowing out of the steam outlet directly flows out of the steam chamber 124 through the steam through hole 1121 directly opposite to the steam outlet.

[0064] In order to improve the convenience of setting the steam inlet 125, in the present embodiment, the steam inlet 125 is arranged on the side of the first chamber 1241 away from the second chamber 1242, so that the steam inlet 125 can be arranged away from the second chamber 1242, thereby extending the actual diversion path of each steam diversion channel 21 on the basis of the unchanged height of the first chamber 1241 in the vertical direction, thereby improving the diversion effect.

[0065] In this embodiment, the first chamber 1241 is located below the second chamber 1242, that is, the steam inlet 125 is arranged at the bottom of the steam chamber 124. This arrangement enables the hot steam entering the steam chamber 124 from the steam inlet 125 to not only flow upward through the diverter 2 to the second chamber 1242 under the action of the steam intake pressure, but also flow upward to the second chamber 1242 under the upward rising action of the hot steam, thereby ensuring the smoothness and reliability of the flow of the hot steam and preventing the hot steam from gathering in the steam inlet 125 and the first chamber 1241. In other embodiments, the first chamber 1241 may also be located below the second chamber 1242.

[0066] Furthermore, the steam inlet 125 is arranged in the middle of the steam chamber 124 along the front-to-back direction. This arrangement is conducive to the steam entering the first chamber 1241 from the steam inlet 125 to diffuse to the front and rear sides under the action of the diverter 2, which is more conducive to ensuring the uniformity of the steam flowing out of the first chamber 1241 in the front-to-back direction and simplifying the structure of the diverter 2. In other embodiments, the steam inlet 125 can also be arranged at other positions of the steam chamber 124 along the front-to-back direction.

[0067] All steam diversion channels 21 are radially distributed with the steam inlet 125 as the center, and each steam diversion channel 21 is distributed in a flared shape in the direction away from the steam inlet 125. Since the opening area of ​​the steam inlet 125 is small, and the length of the steam chamber 124 in the front-to-back direction is large, each steam diversion channel 21 is arranged in a flared shape in the direction away from the steam inlet 125, so that the channel cross-sectional area of ​​each steam diversion channel 21 gradually increases in the direction away from the steam inlet 125, thereby facilitating the steam entering from the steam diversion channel 21 to diffuse in the front-to-back direction under the drainage effect of the steam diversion channel 21.

[0068] In the present embodiment, the front end cavity wall of the steam chamber 124 forms the front channel wall of the frontmost steam diversion channel 21, and the rear end cavity wall of the steam chamber 124 forms the rear channel wall of the rearmost steam diversion channel 21, that is, the diversion steam outlet of the frontmost steam diversion channel 21 extends to the front end of the steam chamber 124, and the diversion steam outlet of the rearmost steam diversion channel 21 extends to the rear end of the steam chamber 124, thereby ensuring that the steam flowing out of the first chamber 1241 can cover the rear end and the front end of the first chamber 1241.

[0069] In order to further improve the uniformity of the steam entering the cooking cavity 111 in the front-to-back direction, in the present embodiment, a plurality of vent groups 112 are arranged at intervals along the front-to-back direction on both sides of the left and right sides of the cooking cavity 111, and the plurality of vent groups 112 correspond one-to-one with the diversion steam outlets of the steam diversion channel 21 in the front-to-back direction, and each diversion steam outlet is connected to all the steam holes 1121 of the corresponding vent group 112.

[0070] That is, in this embodiment, the multiple steam holes 1121 on each side can be divided into multiple vent groups 112 according to the number of steam diversion channels 21 and the position of the diversion steam outlet of each steam diversion channel 21. Each vent group 112 is located above the diversion steam outlet of the corresponding steam diversion channel 21. The hot steam flowing upward from the diversion steam outlet of a steam diversion channel 21 generally flows out through the steam hole 1121 in the corresponding vent group 112.

[0071] Each vent group 112 includes a plurality of steam holes 1121, and the total opening area of ​​all steam holes 1121 of each steam hole group is S1, and the opening area of ​​the shunt steam inlet of the steam channel corresponding to the steam hole group is S2, and S1 is positively correlated with S2. Since S1 is positively correlated with S2, it means that if the total opening area of ​​a vent group 112 is larger, the opening area of ​​the shunt steam inlet of the corresponding steam shunt channel 21 is larger, and the amount of steam entering the corresponding steam shunt channel 21 from the shunt steam inlet is larger, and it is better to ensure that the amount of steam flowing out of each steam hole 1121 can be consistent.

[0072] In order to further ensure the uniformity of the steam entering the cooking cavity 111 in the front-to-back direction, in this embodiment, the plurality of steam through holes 1121 are distributed in a determinant manner along the front-to-back direction and the vertical direction. That is, the steam through holes 1121 are evenly spaced in a plurality of rows along the front-to-back direction, and each row of steam through holes 1121 includes a plurality of steam through holes 1121 evenly spaced in the vertical direction, thereby ensuring the uniform distribution of the plurality of steam through holes 1121 in the front-to-back direction, thereby facilitating the uniformity of the amount of steam flowing out of the steam through holes 1121 in the front-to-back direction. That is, in this embodiment, each vent group 112 includes a plurality of rows of steam through holes 1121.

[0073] Furthermore, the ratio of S1 to S2 of a steam diversion channel 21 is A, and the A values ​​of all steam diversion channels 21 are roughly equal, which is more conducive to ensuring that the amount of steam flowing out of each steam hole 1121 can be roughly consistent in area, thereby ensuring that the steam entering the cooking cavity 111 from the steam cavity 124 can be consistent in area in the front-to-back direction.

[0074] It is worth mentioning that the above-mentioned "tending to be consistent" means that they can be completely consistent, but a certain error is allowed. For example, at various locations in the front and back directions of the steam chamber 124, if the maximum amount of steam entering the cooking chamber 111 is Imax and the minimum amount of steam is Imin, Imax / Imin=1~1.2 is allowed.

[0075] In order to simplify the structure of the diverter 2, in the present embodiment, the width of the diverter steam outlets of the plurality of steam diverter channels 21 in the front-to-back direction gradually increases in the direction away from the steam inlet 125, that is, the front-to-back width of the steam outlet of the steam diverter channel 21 close to the steam inlet 125 is smaller, while the front-to-back width of the diverter steam outlet of the steam diverter channel 21 away from the steam inlet 125 is larger, thereby making the amount of steam entering each steam diverter channel 21 gradually decrease in the direction close to and away from the steam inlet 125, thereby effectively preventing a large amount of steam from directly flowing out from the steam inlet 125 through the diverter steam outlet close to the steam inlet 125, and preventing the steam from converging to the diverter steam outlet of the steam diverter channel 21 closest to the steam inlet 125, thereby better ensuring the diversion effect.

[0076] In this embodiment, a plane passing through the center line of the steam inlet 125 and perpendicular to the left and right direction is set as the first symmetry plane, and the flow divider 2 is symmetrically arranged relative to the first symmetry plane. That is, the plurality of steam flow divider channels 21 are symmetrically arranged relative to the symmetry plane, thereby ensuring that the steam diverted to the front and rear sides by the steam inlet 125 can be symmetrically arranged relative to the symmetry plane, further improving the uniformity of the steam flowing into the steam chamber 124 in the front and rear directions; at the same time, this arrangement is also conducive to simplifying the structure of the flow divider 2.

[0077] In order to reduce the number of steam diversion channels 21 while ensuring the diversion effect, in this embodiment, preferably, the number of steam diversion channels 21 is 4 to 7.

[0078] In this embodiment, five steam diverter channels 21 are provided, including a first diverter channel 21a, two second diverter channels 21b and two third diverter channels 21c, wherein the first diverter channel 21a is provided vertically opposite to the steam inlet 125, the two second diverter channels 21b are respectively located at the front and rear sides of the first diverter channel 21a, wherein one third diverter channel 21c is located at the front side of the second diverter channel 21b on the front side, and the other third diverter channel 21c is located at the rear side of the second diverter channel 21b on the rear side. The opening area of ​​the diverter steam inlet of the first diverter channel 21a, the second diverter channel 21b and the third diverter channel 21c gradually increases, and the area of ​​the steam outlet of the first diverter channel 21a, the second diverter channel 21b and the third diverter channel 21c gradually increases.

[0079] In this embodiment, the flow divider 2 includes a plurality of flow divider plate portions 22 arranged around the steam inlet 125, the first ends of the plurality of flow divider plate portions 22 are relatively closed in the direction toward the steam inlet 125, the second ends of the plurality of flow divider plate portions 22 are arranged at intervals in the front-to-back direction, a steam flow divider channel 21 is formed between two adjacent flow divider plate portions 22, and the left and right sides of each flow divider plate portion 22 are both in contact with the cavity wall of the steam cavity 124. This arrangement enables the plurality of steam flow divider channels 21 to be separated by the flow divider plate portions 22 in the front-to-back direction, and the left and right cavity walls of the steam cavity 124 form the left and right channel walls of the steam flow divider channel 21, which improves the reliability of the separation between two adjacent steam flow divider channels 21 and also helps to simplify the structure of the flow divider 2.

[0080] In this embodiment, the flow divider 2 and the steam hood 12 are separately arranged, and a connecting plate portion 23 is connected between the left side or right side of two adjacent flow divider plate portions 22, so that multiple flow divider plate portions 22 are connected through the connecting plate portion 23, so that the flow divider 2 can form an integral structure, realize the separate arrangement of the flow divider 2 and the steam hood 12, and facilitate the separate processing of the flow divider 2 and the steam hood 12, thereby reducing the processing difficulty of the flow divider 2 and the steam hood 12. In other embodiments, multiple flow divider plate portions 22 are separately arranged, and the side of each flow divider plate portion 22 facing away from the cooking cavity 111 is welded or integrally formed with the steam hood 12.

[0081] Furthermore, the flow divider 2 is formed by bending in one piece, thereby simplifying the processing difficulty of the flow divider 2 and improving the processing convenience of the flow divider 2. That is, in this embodiment, a plurality of connecting plate portions 23 arranged in sequence along the front-to-back direction are arranged alternately in the left-to-right direction, that is, for the flow divider 22 located in the middle, both the left and right sides thereof are connected with connecting plate portions 23, and the two connecting plate portions 23 are respectively connected to the flow divider 22 on the front and rear sides of the flow divider 22, thereby facilitating the formation of the staggered flow divider 22 and connecting plate portions 23 by bending in sequence. In other embodiments, each connecting plate portion 23 can also be welded to the adjacent flow divider 22.

[0082] In order to improve the installation convenience of the flow divider 2 in the steam chamber 124, the two outermost flow divider plate portions 22 are fitted with the chamber wall of the steam chamber 124 where the steam inlet 125 is provided, so that when the flow divider 2 is installed, the installation position of the flow divider 2 in the steam chamber 124 is limited by the fitting of the flow divider plate portions 22 with the chamber wall of the steam chamber 124, thereby ensuring the installation stability of the flow divider 2 in the steam chamber 124. In this embodiment, the outermost flow divider plate portions 22 are fitted with the chamber bottom of the steam chamber 124.

[0083] Furthermore, the diverter 2 is detachably connected to the steam hood 12 to improve the convenience of disassembly and assembly of the diverter 2. Preferably, the diverter 2 is inserted into the steam chamber 124, so that no other parts are needed to fasten the steam hood 12 and the diverter 2, so as to simplify the structure of the inner pot assembly 10 and the cooking device, and at the same time improve the convenience of installation and disassembly of the diverter 2.

[0084] In order to improve the convenience of installation and removal of the steam hood 12 on the inner pot 11, the steam hood 12 includes a main hood portion 121 with an opening on one side, and the main hood portion 121 and the cooking cavity 1 are surrounded to form a steam cavity 124; a mounting edge portion 122 extends outward from the periphery of the open end surface of the main hood portion 121, and the mounting edge portion 122 is connected to the cooking cavity 1 through a fastening structure, so that the fastening structure can be located outside the steam cavity 124 of the mounting edge portion 122, which is more conducive to ensuring that the steam in the steam cavity 124 will not leak through the connection position between the fastening structure and the steam hood 12. Preferably, a plurality of fastening structures are arranged at intervals around the mounting edge portion 122 to ensure the installation stability of the steam hood 12 on the inner pot 11.

[0085] In order to ensure the sealing of the connection between the steam hood 12 and the cooking cavity 1, a sealing ring is sandwiched between the open end surface of the steam hood 12 and the cooking cavity 1, and the sealing ring surrounds the steam through hole 1121 and the outer side of the steam cavity 124, thereby ensuring the sealed connection between the steam hood 12 and the cooking cavity 1, and preventing steam from leaking through the connection between the cooking cavity 1 and the steam hood 12. Preferably, the installation edge 122 is provided with an annular sealing groove 1221, and the sealing ring is installed in the sealing groove 1221.

[0086] In this embodiment, the bottom height of the steam chamber 124 gradually decreases from the front and rear ends to the steam inlet 125, that is, the steam inlet 125 is opened at the lowest point of the bottom of the steam chamber 124, which is conducive to the convergence of condensed water in the steam chamber 124 to the steam inlet 125, and is conducive to the discharge of condensed water in the steam chamber 124.

[0087] like Figure 6 and Figure 7 As shown, the steam generating assembly 20 includes two steam pipes 202, and the steam generated by the steam generator 201 is respectively supplied to the two steam chambers 124 through the two steam pipes 202. This arrangement enables one steam generator 201 to supply steam to the two steam chambers 124, which is conducive to ensuring the synchronization of the steam supply to the steam chambers 124 on both sides and reducing costs. In other embodiments, a steam generator 201 may be provided corresponding to the steam chamber 124 on each side.

[0088] The steam generator 201 is preferably disposed at the rear side of the cooking cavity 1, thereby preventing the steam generator 201 from occupying the upper space of the cooking cavity 1. In other embodiments, the steam generator 201 may also be disposed at the top of the cooking cavity 1. The two steam pipes 202 are preferably disposed symmetrically relative to the second symmetry plane to improve the consistency of steam supply from the steam generator 201 to the two steam cavities 124.

[0089] The steam generator 201 is lower than the steam inlet 125, and the steam pipe 202 tends to extend downward from the steam inlet 125 to the steam generator 201, so that the condensed water gathered at the steam inlet 125 can flow back to the steam generator 201 through the steam pipe 202 in turn, which is conducive to the recovery and reuse of the condensed water, and the steam supply pipeline and the condensed water return pipeline are shared, simplifying the pipelines inside the cooking equipment.

[0090] It can be understood that the tendency of the steam pipe 202 to extend obliquely downward from the steam inlet 125 to the steam generator 201 means that the steam pipe 202 can extend downward from its gas outlet end to the gas inlet end, or part of the steam pipe 202 can extend downward and the rest of the pipe can be arranged horizontally.

[0091] In order to further improve the connection convenience between the steam pipe 202 and the steam hood 12, in this embodiment, the steam hood 12 further includes a connecting pipe portion 123 connected to the bottom of the main hood portion 121, and the steam inlet 125 is communicated with the inner cavity of the connecting pipe portion 123, and the connecting pipe portion 123 is detachably sealed and connected to the steam pipe 202. By providing the connecting pipe portion 123, it is convenient to achieve a sealed connection between the steam hood 12 and the steam pipe 202 through the cooperation of the connecting pipe portion 123 and the steam pipe 202, thereby simplifying the sealed connection structure between the two. In other embodiments, the gas outlet end of the steam pipe 202 can also be sealed and inserted at the steam inlet 125.

[0092] The gas port is connected to an exhaust pipe 30, which is used to discharge the gas in the cooking cavity 111 out of the cooking device. The exhaust position and exhaust method corresponding to the exhaust pipe 30 can be specifically set according to the type of cooking device, and the present invention does not limit this.

[0093] Embodiment 2

[0094] The present embodiment provides an inner pot assembly 10 and a cooking device comprising the inner pot assembly 10, and the inner pot assembly 10 provided in the present embodiment is a further improvement on the inner pot assembly 10 in the first embodiment, and the present embodiment will not repeat the same contents as the first embodiment.

[0095] like Figure 8 As shown, in this embodiment, a partition plate 3 is provided in the second chamber 1242 , and the left and right sides of the partition plate 3 are respectively in contact with the left and right side walls of the steam chamber 124 , and two adjacent groups of vent holes 112 are separated by the partition plate 3 .

[0096] The inner pot assembly 10 and cooking equipment provided in this embodiment separate two adjacent vent groups 112 by setting a partition plate 3, so that the steam flowing into the second chamber 1242 from a steam diversion channel 21 can only flow out from the steam through hole 1121 in the vent group 112 corresponding to the steam diversion channel 21, which is beneficial to ensure the effect of the diversion component 2 on steam diversion.

[0097] The partition plate 3 can be formed integrally with the steam cover 12 , or the partition plate 3 can be plugged or welded to the bottom of the steam chamber 124 . The present embodiment does not limit the installation method of the partition plate 3 on the steam cover 12 .

[0098] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
