[0043] Embodiment 1

[0044] like Figures 1 to 5 The present embodiment provides a cooking device with a microwave cooking function, which can discharge the air in the cooking cavity 11 out of the cooking cavity 11 before or when cooking starts, so as to reduce the oxygen content in the cooking cavity 11, realize anaerobic or low-oxygen cooking, improve the taste of cooked food and the nutritional value of cooked food, and reduce the probability of ignition during microwave cooking, thereby improving the safety of the cooking device. The cooking device may be a microwave-steaming machine with a microwave cooking function and a steam cooking function, or a microwave-steaming machine with a microwave cooking function, a steaming function, and a baking function.

[0045] Specifically, the cooking device includes a body, an inner pot assembly 10, a door, a steam generating assembly 20, a microwave cooking module and a control device 50. The body includes a frame 60 and a casing wrapped around the outer side of the frame 60; the inner pot assembly 10 is arranged inside the body and has a cooking cavity 11 with a front opening; the door is arranged at the front side of the body and can selectively open or close the front opening of the cooking cavity 11; the steam generating assembly 20 is used to supply steam to the cooking cavity 11; and the microwave cooking module is used to realize the microwave cooking function of the cooking device. The control device 50 is connected to the microwave cooking module and the steam generating assembly 20 in communication to control the operation of the cooking device.

[0046] In this embodiment, the inner pot assembly 10 includes a cooking cavity 1 and a steam cover 2. The cooking cavity 1 has a cooking cavity 11 with an opening at the front. Meshes 12 are provided on the upper parts of the left and right sides of the cooking cavity 1. The meshes 12 can intercept microwaves. The cooking cavity 1 has an exhaust hole at the lower part of the cooking cavity 11. The left and right outer sides of the cooking cavity 1 are provided with steam covers 2. The steam cover 2 and the cooking cavity 1 are surrounded to form a steam cavity 211. The steam cavity 211 is connected to the cooking cavity 11 through the mesh 12, and the steam cavity 211 has a steam inlet 212. The steam generating assembly 20 passes steam into the steam cavity 211 through the steam inlet 212.

[0047] Before cooking begins, the steam generating assembly 20 generates hot steam and passes the hot steam into the steam chambers 211 on both sides of the cooking chamber 11, and the steam in the steam chamber 211 flows into the cooking chamber 1 through the mesh 12. Since the density of the hot steam is greater than that of the cold air in the cooking chamber 11, the hot steam entering the cooking chamber 11 forms a steam layer at the upper part of the cooking chamber 11, and when the hot steam continuously flows into the cooking chamber 11, the steam layer expands downward and squeezes the air in the cooking chamber 11 downward, so that the air is squeezed out of the cooking chamber 11 through the exhaust port until the hot steam fills the cooking chamber 11.

[0048] The inner pot assembly 10 and the cooking device provided in the present embodiment are provided with mesh holes 12 on the left and right sides of the cooking cavity 1 to allow steam to pass through, so that there is no gap located on the inner side of the cooking cavity 11 at the connection between the cooking cavity 1 and the steam cover 2, which can effectively prevent microwaves from leaking through the connection between the cooking cavity 11 and the steam cavity 211 when the cooking device adopts microwave cooking, reduce microwave loss, and effectively reduce the probability of ignition during microwave cooking, thereby improving the safety and user experience of the cooking device; by providing steam cavities 211 connected to the cooking cavity 11 at the upper parts of the left and right sides of the cooking cavity 1, the hot steam with a smaller seal enters the cooking cavity 11 and forms a layer in the vertical direction with the relatively larger seal of cold air, so that when the hot steam continues to enter the cooking cavity 11, the hot steam layer will have an impact on the cold air. The air is squeezed downward, so that the oxygen-containing air is discharged to the outside of the cooking cavity 11 through the exhaust port, thereby realizing anaerobic or low-oxygen cooking of the cooking equipment. At the same time, due to the stratification of hot steam and cold air, the mixing amount of air and hot steam in the air discharge process can be reduced, thereby reducing the discharge of hot steam and reducing energy consumption; by arranging steam chambers 211 on the left and right sides of the cooking cavity 11, it is possible to achieve spray-type steam intake on both sides of the cooking cavity 11, so that the steam can quickly fill the upper space of the cooking cavity 11, thereby facilitating the rapid oxygen and exhaust of the cooking cavity 11; furthermore, since the steam chambers 211 are arranged on the upper left and right sides of the cooking cavity 11, the condensed water generated during the steam intake process will not directly drip downward into the food in the cooking cavity 11, which is conducive to ensuring the taste of the cooked food and improving the cooking experience.

[0049] In this embodiment, a plurality of mesh holes 12 are arranged side by side along the front-to-back direction, that is, the steam in the coverage area of ​​the mesh holes 12 is in a long strip structure extending along the front-to-back direction, so as to increase the coverage area of ​​the mesh holes 12 in the front-to-back direction, thereby ensuring the uniformity of the steam intake of the cooking cavity 11 in the front-to-back direction.

[0050] In this embodiment, the depth of the cooking cavity 11 along the front-to-back direction is L 0 , the coverage of the mesh 12 along the front-to-back direction is L 1 , L 0 ≥L 1 ≥ 0.7 L0 , and preferably L 1 ≥ 0.8 L 0 , thereby increasing the steam intake range in the front-to-back direction, thereby improving the steam intake uniformity in the front-to-back direction of the cooking cavity 11, and making it more conducive for hot steam to quickly fill the top space of the cooking cavity 11.

[0051] The height of the cooking cavity 11 in the vertical direction is H, and the coverage width of the mesh 12 in the vertical direction is W, 0.05H≤W≤0.3H, thereby enabling the mesh 12 to have a certain width in the vertical direction to ensure the air intake speed of the steam into the cooking cavity 11, while avoiding the mesh 12 covering too large a width to cause more mixing with the air in the cooking cavity 11 during the air discharge process.

[0052] It is worth noting that the coverage range of the mesh 12 in the front-to-back direction is the length range of the area where the mesh 12 is opened on the side wall of the cooking cavity 1 in the front-to-back direction, that is, it also refers to the distance between the frontmost mesh 12 and the rearmost mesh 12 in the front-to-back direction; the coverage range of the mesh 12 in the vertical direction is the height of the area where the mesh 12 is opened on the side wall of the cooking cavity 1 in the vertical direction, that is, it refers to the distance between the uppermost mesh 12 and the lowermost mesh 12 in the vertical direction.

[0053] The height of the cooking cavity 11 in the vertical direction is H, and the distance between the upper side of the area covered by the mesh 12 and the top wall of the cooking cavity 11 is d. 1 , 0<d 1 ≤0.25H, so that the steam inlet position of the cooking cavity 1 can be closer to the top of the cooking cavity 11, thereby quickly squeezing the air at the top of the cooking cavity 11 downward, improving the air exhaust effect and air discharge effect.

[0054] The cooking cavity 11 has a symmetry plane perpendicular to the left-right direction, and the mesh holes 12 on both sides are symmetrically arranged relative to the symmetry plane, thereby making the steam inlet arrangement on both sides of the cooking cavity 11 more consistent and better ensuring the uniformity of steam inlet from the mesh holes 12 on the left and right sides.

[0055] In this embodiment, the distance between the exhaust port and the top of the cooking cavity 11 is d 2 , H>d 2 ≥0.75H, so that the exhaust port is arranged as close to the bottom of the cooking cavity 11 as possible, so as to better promote the discharge of air at the bottom of the cooking cavity 11, facilitate the rapid exhaust of air, and improve the exhaust efficiency. In this embodiment, the exhaust port is arranged on the rear wall of the cooking cavity 11, and in other embodiments, the exhaust port can be arranged on the left and right side walls of the cooking cavity 11.

[0056] like Figures 2 to 4As shown, in this embodiment, the cooking cavity 1 and the steam cover 2 are detachably connected through a fastening structure, which facilitates the maintenance and replacement of the steam cover 2 and improves the convenience of disassembly and assembly of the inner pot assembly 10 and the cooking device. In other embodiments, the steam cover 2 can also be welded to the outside of the cooking cavity 1.

[0057] The steam cover 2 is a cover structure with one side open, and the open end face of the steam cover 2 faces the outer wall of the cooking cavity 1, so that the outer wall of the cooking cavity 1 closes the opening of the steam cavity 211. In order to ensure the sealing of the connection between the steam cover 2 and the cooking cavity 1, a sealing ring 4 is sandwiched between the open end face of the steam cover 2 and the cooking cavity 1, and the sealing ring 4 surrounds the mesh 12 and the outer side of the steam cavity 211, thereby ensuring the sealed connection between the steam cover 2 and the cooking cavity 1, and preventing steam from leaking through the connection between the cooking cavity 1 and the steam cover 2.

[0058] The fastening structure includes a mounting component 3 and a locking component. The first end of the mounting component 3 is welded or integrally formed on the outside of the cooking cavity 1, the second end of the mounting component 3 passes through the steam cover 2, and the locking component is detachably connected to the second end of the mounting component 3 to press the steam cover 2 against the outside of the cooking cavity 1. In this arrangement, since the first end of the mounting component 3 is welded or integrally formed with the outer wall of the cooking cavity 1, it is not necessary to provide a hole structure for connecting the mounting component 3 on the cooking cavity 1, thereby preventing the microwave in the cooking cavity 1 from leaking through the hole structure, and further reducing the probability of ignition during microwave cooking; at the same time, by arranging a detachable connection between the locking component and the second end of the mounting component 3, the locking component can press the steam cover 2 against the cooking cavity 1, which is more conducive to achieving the sealing of the connection between the steam cover 2 and the cooking cavity 1.

[0059] In order to improve the connection convenience between the steam cover 2 and the cooking cavity 1, the steam cover 2 includes a main cover part 21 with an opening on one side, and the main cover part 21 and the cooking cavity 1 together form a steam cavity 211; a mounting edge part 22 extends outward from the periphery of the open end surface of the main cover part 21, and the mounting edge part 22 is connected to the cooking cavity 1 through a fastening structure, so that the fastening structure can be located outside the steam cavity 211 of the mounting edge part 22, which is more conducive to ensuring that the steam in the steam cavity 211 will not leak through the connection position between the fastening structure and the steam cover 2. Specifically, a mounting hole 221 is opened on the mounting edge part 22, and the mounting hole 221 is arranged one-to-one with the fastening structure. The mounting component 3 passes through the mounting hole 221, and the locking component is crimped to the side of the mounting edge part 22 away from the cooking cavity 1.

[0060] In this embodiment, the mounting component 3 is a screw structure, the threaded section of the screw structure passes through the mounting hole 221, and the fastening component is a locking nut, which is screwed on the threaded section to press the mounting edge 22. This arrangement can adjust the pressure applied by the locking nut to the steam cover 2 by the screwing depth of the locking nut relative to the threaded section, thereby better ensuring that the locking nut can press the steam cover 2.

[0061] In another embodiment, the mounting component 3 may be a mounting column, the mounting column is provided with an internal threaded hole, the locking thread is a locking screw, the locking screw thread is screwed on the mounting column, and the screw head of the locking screw is pressed against the steam cover 2. In another embodiment, the mounting component 3 may be a mounting column, the locking component may be a locking sleeve, the locking sleeve interference sleeve is arranged outside the second end of the mounting column, and the end face of the locking sleeve presses the steam cover 2.

[0062] In order to improve the installation stability and sealing performance of the steam cover 2 and the cooking cavity 1 after installation, multiple fastening structures are arranged at intervals around the steam cavity 211. Specifically, multiple fastening structures are arranged at intervals along the circumference of the installation edge 22. Furthermore, since the steam cover 2 is a long strip structure extending in the left-right direction, multiple fastening structures are arranged at intervals along the front-back direction on both the upper and lower sides of the steam cover 2; at least one fastening structure is arranged at both the front and rear ends of the steam cover 2.

[0063] Furthermore, the sealing ring 4 is provided with a through hole 41, which corresponds to the mounting hole 221 one by one. The mounting component 3 passes through the aligned through holes 41 and the mounting hole 221 in sequence, thereby enabling the sealing ring 4 to be firmly clamped between the steam cover 2 and the cooking cavity 1 under the pressure applied by the fastening component, thereby effectively ensuring the sealing effect.

[0064] In order to improve the convenience of installing the sealing ring 4, in this embodiment, a sealing groove 222 is provided on the installation edge 22, and the sealing ring 4 is arranged in the sealing groove 222, and the groove depth of the sealing groove 222 is less than the thickness of the sealing ring 4 when it is not squeezed. A mounting hole 221 is provided at the groove bottom of the sealing groove 222. In this way, the sealing ring 4 is installed and positioned on the steam cover 2.

[0065] like Figures 3 to 6As shown, the steam generating assembly 20 includes a steam generator 201 and a steam pipe group, and the steam generated by the steam generator 201 is passed through the steam pipe group to the steam chambers 211 on the left and right sides. In this embodiment, the steam pipe group includes a steam supply main pipe 202 and two branch pipes 203, one end of the steam supply main pipe 202 is connected to the steam outlet of the steam generator 201, and the other end of the steam supply main pipe 202 group is connected to the air inlet ends of the two branch pipes 203, and the air outlet ends of the two branch pipes 203 are respectively sealed and connected to the steam inlets 212 of the two steam chambers 211. That is, the steam generated by the steam generator 201 flows out through the steam supply main pipe 202 and is supplied to the two steam chambers 211 after being split by the two branch pipes 203. This arrangement allows one steam generator 201 to supply steam to the two steam chambers 211, which is conducive to ensuring the synchronization of steam supply to the steam chambers 211 on both sides and reducing costs. In other embodiments, a steam generator 201 may be provided corresponding to the steam chamber 211 on each side.

[0066] The two branch pipes 203 have the same length and diameter, so that the steam volume and steam supply speed flowing to the steam chambers 211 on both sides through the two branch pipes 203 are the same, which is conducive to improving the uniformity of the steam flow on the left and right sides of the cooking chamber 11. More preferably, the two branch pipes 203 are symmetrically arranged, so that the steam inlet to the steam chambers 211 on the left and right sides can be uniformly achieved.

[0067] 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.

[0068] In this embodiment, the steam inlet 212 is arranged at the bottom of the steam cavity 211, and a drainage structure is arranged in the steam cavity 211, and the drainage structure guides the condensed water in the steam cavity 211 to converge toward the steam inlet 212. This arrangement enables the condensed water to converge at the steam inlet 212 under the drainage effect of the drainage structure when there is condensed water in the steam cavity 211, thereby facilitating the condensed water to be discharged through the steam inlet 212, thereby avoiding the accumulation of condensed water in the steam cavity 211, and improving the cleaning convenience of the inner pot assembly 10 and the cooking device.

[0069] In this embodiment, the steam generator 201 is lower than the steam inlet 212, the branch pipe 203 has a tendency to extend obliquely downward from the steam inlet 212 to the steam supply main pipe 202, and the steam supply main pipe 202 has a tendency to extend downward from the air inlet end of the branch pipe 203 to the steam outlet of the steam generator 201. As a result, the condensed water gathered at the steam inlet 212 can flow back to the steam generator 201 through the branch pipe 203 and the steam supply main pipe 202 in sequence, 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 pipeline inside the cooking device.

[0070] It can be understood that the tendency of the branch pipe 203 to extend obliquely downward from the steam inlet 212 to the steam supply main pipe 202 means that the branch pipe 203 can extend downward from its outlet end to the inlet end, or part of the pipe section of the branch pipe 203 can extend downward and the remaining part of the pipe section can be arranged horizontally; similarly, the tendency of the steam supply main pipe 202 to extend downward from the outlet end of the branch pipe 203 to the outlet of the steam generator 201 means that the steam supply main pipe 202 can extend downward from its outlet end to the inlet end, or part of the pipe section can extend downward and the other part of the pipe section can be arranged horizontally.

[0071] Furthermore, the steam inlet 212 is lower than the mesh 12 to prevent condensed water in the steam cavity 211 from flowing into the cooking cavity 11 through the mesh 12 .

[0072] In this embodiment, the drainage structure includes a drainage slope 213 formed at the bottom of the steam chamber 211. In the front-to-back direction, the drainage slope 213 extends obliquely upward from the steam inlet 212 to the end of the steam chamber 211. This drainage structure is simple in structure, easy to set up and has a good drainage function, which effectively reduces the processing cost of the steam cover 2 and the liner assembly 10.

[0073] In this embodiment, the steam inlet 212 is arranged in the middle of the steam cavity 211 in the front-to-back direction, so that the steam entering the steam cavity 211 from the steam inlet 212 can diffuse to the front and rear sides, thereby improving the uniformity of the steam in the front-to-back direction of the steam cavity 211, thereby improving the uniformity of the steam inlet in the front-to-back direction of the cooking cavity 11.

[0086] Furthermore, the branch pipe 203 and / or the outer side of the steam cover 2 may be wrapped with an insulation layer to insulate the branch pipe 203 , thereby reducing heat loss when steam flows from the steam generator 201 to the steam chamber 211 .

[0087] Embodiment 3

[0088] The present embodiment provides an inner pot assembly 10 and a cooking device including the inner pot assembly 10.

In this arrangement, since the opening area of ​​the rectifying holes of the rectifying plate facing the steam inlet 212 is relatively small, while the opening area of ​​the rectifying holes away from the steam inlet 212 gradually increases, the resistance of steam passing through the rectifying holes gradually decreases from the position of the steam inlet 212 to the position away from the steam inlet 212, thereby guiding the steam entering from the steam inlet 212 to flow to both sides of the steam chamber 211, achieving the rectification effect of the steam inside the rectifying chamber, and further improving the uniformity of the steam in the front-to-back direction in the outlet chamber.

[0091] In another embodiment, the rectification structure includes a rectification tube, which extends in the front-to-back direction and is spaced apart from the wall of the steam chamber 211.
