[0002] As people's living standards improve, their demands for product quality also increase. Air fryers, as kitchen appliances labeled as low-fat and healthy, have become popular with many consumers. Current air fryers use a motor to drive fan blades that rotate at high speed within the cooking chamber. Under the action of the heating element, high-speed hot air is generated. This high-speed hot air undergoes efficient convection heat exchange with the food, enabling rapid cooking. Furthermore, air fryers can be equipped with a steam generator to supply steam into the cooking chamber, thus preventing the high-speed hot air from removing moisture from the surface and interior of the food, which could result in a dry and tough texture.

[0003] However, in existing air fryers, the water flow from the steam generator directly enters the vaporization chamber. When the air fryer platform or the air fryer itself is tilted, the high-temperature steam in the vaporization chamber is prone to backflow, which can damage the water supply components and cause dry burning in the vaporization chamber, damaging the steam generator and affecting the lifespan and safety of the air fryer. There is room for improvement. Utility Model Content

[0040] The following is for reference. Figures 1-9 According to the embodiments of the present invention, the cooking device 100 can prevent water backflow in the vaporization chamber 23, thereby preventing damage to the steam generator 2, extending the service life of the cooking device 100, and improving the safety of use.

[0041] like Figures 1-9 As shown, a cooking device 100 according to an embodiment of the present invention includes a device body 1 and a steam generator 2.

[0042] The equipment body 1 has a cooking chamber 11. A steam generator 2 is installed inside the equipment body 1. The steam generator 2 has a connecting chamber 27, a connecting channel 24, and a vaporization chamber 23. The connecting channel 24 has a connecting inlet 241 and a connecting outlet 242. The connecting inlet 241 is connected to the connecting chamber 27, and the connecting outlet 242 is connected to the vaporization chamber 23. The vaporization chamber 23 is connected to the cooking chamber 11 through a steam channel 25. The steam generator 2 also has a vent 21 connected to the connecting chamber 27. The vent 21 is used to inject water into the connecting chamber 27. The vent 21 is higher than the connecting outlet 242, and the connecting outlet 242 is higher than the connecting inlet 241.

[0043] The cooking equipment 100 can be an air fryer, steam oven, or other type of oven, used for defrosting, frying, cooking, and baking food. It has an internal cavity that can be used to hold food. Users can put food into the cavity and then perform defrosting, frying, cooking, and baking operations to meet different user needs.

[0044] Specifically, the device body 1 is the shell structure of the cooking device 100, which includes a cooking cavity 11 and a mounting cavity 12. The cooking cavity 11 has an opening that opens to one side, and a cooking bucket 13 is installed inside the cooking cavity 11. The cooking bucket 13 is retractable relative to the cooking cavity 11, so that the user can pull the cooking bucket 13 out of the device body 1 to put food into the cooking bucket 13, and can also put the cooking bucket 13 into the cooking cavity 11 through the opening to put the food to be cooked into the cooking cavity 11, which is convenient to use. The mounting cavity 12 is used to install other structures of the cooking device 100. The mounting cavity 12 and the cooking cavity 11 are spaced apart, so that the structure in the mounting cavity 12 can be separated from the cooking cavity 11, ensuring the operational reliability of the structure in the mounting cavity 12.

[0045] Furthermore, the cooking equipment 100 is also provided with a steam generator 2, which can be used to evaporate water into steam to replenish the moisture of the food, prevent the food from becoming too dry, and improve the taste of the food. The steam generator 2 has a connecting cavity 27, a connecting channel 24 and a vaporization cavity 23. The connecting cavity 27 and the vaporization cavity 23 are distributed in a horizontal direction, and the connecting channel 24 is located between the connecting cavity 27 and the vaporization cavity 23. One end of the connecting channel 24 is set as a connecting inlet 241, and the other end of the connecting channel 24 is set as a connecting outlet 242. The connecting inlet 241 of the connecting channel 24 can be set to connect with the connecting cavity 27, and the connecting outlet 242 of the connecting channel 24 can be set to connect with the vaporization cavity 23.

[0046] Furthermore, the steam generator 2 is also equipped with a steam channel 25. The inlet end 251 of the steam channel is connected to the vaporization chamber 23, and the outlet end 252 of the steam channel is open towards the cooking chamber 11. This allows the vaporization chamber 23 to be connected to the cooking chamber 11 through the steam channel 25. The vaporization chamber 23 can heat the water flow to generate steam. The steam can flow through the steam channel 25 to the cooking chamber 11 to replenish the water in the food and improve its taste. Moreover, the inlet end 251 of the steam channel is located in the upper area of ​​the vaporization chamber 23, which can prevent water from flowing directly from the steam channel 25 into the cooking chamber 11 and ensure its reliability.

[0047] Meanwhile, the steam generator 2 is also provided with a vent 21, which is configured to communicate with the connecting cavity 27. The connecting cavity 27 is connected to the vaporization cavity 23 through the connecting flow channel 24, so that the user can inject water into the connecting cavity 27 through the vent 21, and then the connecting cavity 27 injects water into the vaporization cavity 23 through the connecting flow channel 24, ensuring the reliability of the vaporization cavity 23. Moreover, the vent 21 is configured to be higher than the connecting outlet 242, and the connecting outlet 242 is configured to be higher than the connecting inlet 241, so that after a certain amount of water is stored in the connecting cavity 27, the water in the connecting cavity 27 can enter the vaporization cavity 23 through the connecting outlet 242 of the connecting flow channel 24.

[0048] Furthermore, when the water volume in the vaporization chamber 23 decreases due to evaporation, water can still remain in the connecting channel 24. This water can then be used to seal the connecting channel 24 through the liquid surface, preventing the cooking equipment 100 itself or the platform on which the cooking equipment 100 is placed from tilting, which could cause the high-temperature steam in the vaporization chamber 23 to flow back into the connecting chamber 27 through the connecting channel 24. This can prevent damage to other components in the equipment body 1 and prevent dry burning in the vaporization chamber 23, thus extending the service life of the cooking equipment 100 and ensuring safe use.

[0049] According to the embodiment of the present invention, the cooking device 100, by setting the vent 21 higher than the connecting outlet 242 and setting the connecting outlet 242 higher than the connecting inlet 241, can seal the connecting flow channel 24 through the liquid surface, thereby preventing the high-temperature steam in the vaporization chamber 23 from flowing back, thus preventing damage to other components in the device body 1, preventing the vaporization chamber 23 from dry burning, improving the safety of the cooking device 100, extending the service life of the cooking device 100, and providing better performance and wider applicability.

[0050] In some embodiments, a middle channel 28 is also formed in the steam generator 2. The middle channel 28 is provided with a middle inlet 281 and a middle outlet 282 that are spaced apart in the horizontal direction. The middle inlet 281 is connected to the connecting outlet 242, and the middle outlet 282 is connected to the vaporization chamber 23.

[0051] Specifically, the connecting cavity 27 can be connected to the vaporization cavity 23 via the connecting flow channel 24, and as shown in the figure. Figures 2-5As shown, an intermediate channel 28 is also formed inside the steam generator 2. The intermediate channel 28 is located between the connecting channel 24 and the vaporization chamber 23. The intermediate channel 28 has an intermediate inlet 281 and an intermediate outlet 282. That is, the intermediate inlet 281 can be connected to the connecting outlet 242, and the intermediate outlet 282 can be connected to the vaporization chamber 23. This allows the water flow in the connecting chamber 27 to flow through the connecting channel 24 to the intermediate channel 28, and then through the intermediate channel 28 to flow into the vaporization chamber 23, so as to complete the water injection into the vaporization chamber 23 and ensure the reliability of the vaporization chamber 23 in supplying steam to the cooking chamber 11.

[0052] Furthermore, the intermediate inlet 281 and intermediate outlet 282 of the intermediate channel 28 are arranged to be spaced apart in the horizontal direction, and as shown in the figure. Figures 2-5 As shown, the bottom wall of the vaporization chamber 23 is set lower than the intermediate channel 28, meaning that the water level must be higher than the intermediate channel 28 before water can be injected into the vaporization chamber 23 for water storage. The connecting inlet 241 is set lower than the connecting outlet 242, and the connecting outlet 242 is connected to the intermediate inlet 281, meaning that the intermediate inlet 281 is also set higher than the connecting inlet 241. At this time, the water level is higher than the entire connecting flow channel 24, which can seal the connecting flow channel 24 and prevent the high-temperature steam in the vaporization chamber 23 from flowing back to the vent 21 and other places, damaging other structures, ensuring the service life of the cooking equipment 100, and ensuring safe use.

[0053] In some embodiments, the angle between the line connecting the end point of the vent 21 near the middle channel 28 and the bottom wall end point of the middle outlet 282 and the horizontal direction is A1, satisfying: A1 > 5°.

[0054] Specifically, the user can inject water into the connecting cavity 27 through the vent 21, and the water flow can pass through the connecting channel 24 and the intermediate channel 28 to the vaporization cavity 23, such as... Figure 1 As shown, the end point of the vent 21 near the middle channel 28 can be set as point A, the bottom wall end point of the middle outlet 282 can be set as point C1, and the angle between the line connecting point A and point C1 and the horizontal direction can be set as A1. A1 can be set to satisfy: A1 > 5°, that is, the angle A1 between the line connecting point A and point C1 and the horizontal direction can be set as 6°, 10° or 15°, etc.

[0055] Furthermore, the line connecting point A and point C1 is set to form an angle with the horizontal direction, that is, the end point of the vent 21 near the middle channel 28 is set to be higher than the bottom wall end point of the middle outlet 282, the middle outlet 282 is set to be higher than the connecting inlet 241, and the vent 21 is set to be higher than the connecting outlet 242. That is, the water injected into the vent 21 needs to store a certain amount of water in the connecting cavity 27 and the connecting flow channel 24 before it can flow into the vaporization cavity 23 through the middle outlet 282. When the cooking device 100 is tilted towards the vent 21, there is still water in the connecting flow channel 24, which can then seal the connecting flow channel 24 to prevent the steam in the vaporization cavity 23 from flowing back to the connecting cavity 27 and the vent 21, thus ensuring the safety of the cooking device 100.

[0056] In other embodiments, the angle between the bottom wall endpoint of the intermediate inlet 281 and the endpoint of the connecting inlet 241 away from the intermediate channel 28 and the horizontal direction is A2, satisfying: A2 > 5°.

[0057] Specifically, the user can inject water into the connecting cavity 27 through the vent 21, and the water flow can pass through the connecting channel 24 and the intermediate channel 28 to the vaporization cavity 23, such as... Figure 1 As shown, the bottom wall endpoint of the intermediate inlet 281 can be set as point C2, and the endpoint of the connecting inlet 241 away from the intermediate channel 28 can be set as point B. The angle between the line connecting point C2 and point B and the horizontal direction can be set as A2. A2 can be set to satisfy: A2 > 5°, that is, the angle A2 between the line connecting point C2 and point B and the horizontal direction can be set as 6°, 10° or 15°, etc.

[0058] Furthermore, the line connecting point C2 and point B is set to form an angle with the horizontal direction, that is, the bottom end of the intermediate inlet 281 is set to be higher than the end of the connecting inlet 241 away from the intermediate channel 28, and the connecting outlet 242 is set to be higher than the connecting inlet 241. The connecting outlet 242 is connected to the intermediate inlet 281, that is, the water injected into the drain 21 needs to store a certain amount of water in the connecting channel 24 before it can flow through the intermediate channel 28 to the vaporization chamber 23. When the cooking device 100 is tilted towards the drain 21, there is still water in the connecting channel 24, which can then seal the connecting channel 24 to prevent the steam in the vaporization chamber 23 from flowing back to the connecting chamber 27 and the drain 21, thus ensuring the safety of the cooking device 100.

[0059] In some embodiments, A1 > 10° is satisfied; and / or A2 > 10° is satisfied.

[0060] Specifically, the angle between the line connecting point A and point C1 and the horizontal direction can be set to A1, and A1 can be set to satisfy: A1 > 10°, that is, the angle A1 between the line connecting point A and point C1 and the horizontal direction can be set to 11°, 15° or 20°, etc. The angle between the line connecting point C2 and point B and the horizontal direction can be set to A2, and A2 can be set to satisfy: A2 > 10°, that is, the angle A2 between the line connecting point C2 and point B and the horizontal direction can be set to 11°, 15° or 20°, etc.

[0061] In actual setup, you can ensure that only the angle A1 between the line connecting points A and C1 and the horizontal direction satisfies: A1 > 10°; or you can ensure that only the angle A2 between the line connecting points C2 and B and the horizontal direction satisfies: A2 > 10°; or you can ensure that the angle A1 between the line connecting points A and C1 and the horizontal direction satisfies: A1 > 10°, and simultaneously ensure that the angle A2 between the line connecting points C2 and B and the horizontal direction satisfies: A2 > 10°. This improves the flexibility of the setup and avoids issues such as steam backflow, ensuring the safety of the cooking equipment 100.

[0062] In some embodiments, the connecting channel 24 extends vertically, the intermediate channel 28 extends horizontally, and the connecting channel 24 intersects the intermediate channel 28 perpendicularly.

[0063] Specifically, the connecting channel 24 is connected to the intermediate channel 28, and the intermediate channel 28 is connected to the vaporization chamber 23, and so on. Figures 2-5 As shown, the connecting channel 24 extends vertically, with the connecting inlet 241 located directly below the connecting outlet 242. The intermediate channel 28 extends horizontally, with the intermediate inlet 281 and the intermediate outlet 282 spaced apart horizontally. The connecting outlet 242 is connected to the intermediate inlet 281, allowing the connecting channel 24 and the intermediate channel 28 to intersect perpendicularly at the connecting outlet 242 and the intermediate inlet 281.

[0064] Furthermore, the bottom of the connecting cavity 27 is connected to the connecting inlet 241. When the drain port 21 supplies water into the connecting cavity 27, the water level first rises to the connecting inlet 241. As the water volume gradually increases, the water level moves upward from the connecting inlet 241 to the connecting outlet 242. The connecting outlet 242 is connected to the intermediate inlet 281, so that when the water level rises to the connecting outlet 242, it can flow into the intermediate inlet 281. The intermediate inlet 281 and the intermediate outlet 282 extend horizontally, so that when the water level exceeds the connecting outlet 242, it can flow into the vaporization cavity 23 through the intermediate channel 28. When the water level is lower than the intermediate channel 28, the water flow can still close the connecting channel 24, or when the cooking device 100 is tilted, the water flow in the connecting channel 24 will still exist, thereby preventing the backflow of steam in the vaporization cavity 23, ensuring the safety of the cooking device 100 and extending the service life of the cooking device 100.

[0065] In some embodiments, the vent 21, the connecting channel 24, and the intermediate channel 28 are distributed sequentially in the horizontal direction.

[0066] Specifically, such as Figures 2-5 As shown, the vent 21 can be connected to the connecting channel 24 through the connecting cavity 27, and the connecting channel 24 can be connected to the intermediate channel 28. The vent 21, the connecting channel 24, and the intermediate channel 28 can be distributed sequentially in the horizontal direction. That is, the vent 21 is located on the side away from the vaporization chamber 23. The water flow can first flow through the vent 21 to the connecting channel 24, and then flow through the intermediate channel 28 to the vaporization chamber 23. When a certain amount of water is stored in the connecting cavity 27, the liquid level can be raised above the connecting channel 24. That is, when water is injected into the vaporization chamber 23, the connecting channel 24 is completely sealed by the water flow, which can prevent steam backflow and ensure the reliability of the cooking equipment 100. Furthermore, the sequential distribution of the vent 21, the connecting channel 24, and the intermediate channel 28 in the horizontal direction can reduce the space occupied by the steam generator 2 in the vertical direction, thereby increasing the volume of the cooking equipment 100 and improving the lightweight design.

[0067] In some embodiments, a venting cavity 22 is also formed inside the steam generator 2, the venting cavity 22 is provided with a vent 221, and the venting cavity 22 is connected to the communicating cavity 27.

[0068] Specifically, such as Figures 2-5 As shown, a vent chamber 22 is also formed inside the steam generator 2. The vent chamber 22 is located between the vent 21 and the vaporization chamber 23, and the lower part of the vent chamber 22 can communicate with the connecting chamber 27. The vent chamber 22 is provided with a vent 221, which is located in the upper part of the vent chamber 22. The vent chamber 22 can communicate with the outside through the vent 221, so that outside air can enter the vent chamber 22 through the vent 221.

[0069] When water is injected into the vent 21, outside air can enter the vent chamber 22 through the vent 221 and then into the water storage chamber 311 to ensure pressure balance in the water storage chamber 311 and thus ensure normal water supply. When the water level rises, the vent 21 can be closed. At this time, the water in the vaporization chamber 23 continues to evaporate, causing the water level in the connecting chamber 27 and the vaporization chamber 23 to drop. This allows air to enter the vent 21 again through the vent 221 and then into the water storage chamber 311, allowing water to continue flowing into the vaporization chamber 23 and ensuring reliable water supply.

[0070] In addition, the vent 221 is located at the top of the vent chamber 22. The vent 221 is positioned above the drain port 21, connecting the inlet 241 and the outlet 242. Water will gather below the steam generator 2 under the influence of gravity. Positioning the vent 221 at the top of the vent chamber 22 ensures the connection between the vent 221 and the outside world, thereby ensuring the reliability of the air supply from the vent 221 to the water storage chamber 311. This ensures the continuous water supply from the water storage chamber 311 to the vaporization chamber 23 and prevents water from flowing out of the vent 221 to the outside world, thus ensuring a better user experience.

[0071] In some embodiments, the vent 21, the vent cavity 22 and the connecting channel 24 are spaced apart in the horizontal direction, and the connecting cavity 27 is respectively connected to the lower part of the vent 21, the vent cavity 22 and the connecting channel 24.

[0072] Specifically, the venting cavity 22 is disposed between the vent 21 and the connecting channel 24, that is, the vent 21, the venting cavity 22, and the connecting channel 24 can be distributed at intervals along the horizontal direction, and as... Figures 3-5 As shown, the connecting cavity 27 is located below the venting cavity 22. That is, the connecting cavity 27 can be connected to the vent 21, the lower part of the venting cavity 22, and the connecting inlet 241 of the connecting channel 24, thereby shortening the vertical dimension of the steam generator 2 and improving the weight reduction of the cooking equipment 100.

[0073] Furthermore, by connecting the drain port 21, the lower part of the vent chamber 22, and the connecting inlet 241 of the connecting channel 24 to the connecting chamber 27, the overall water storage capacity of the steam generator 2 can be increased. When the external water supply stops, the water flow in the steam generator 2 can still supply water to the vaporization chamber 23 for a period of time to provide water replenishment time for the user, thereby ensuring the continuous operation of the cooking equipment 100, meeting different usage needs, and improving the user experience.

[0074] In some embodiments, the cooking device 100 further includes a water tank assembly 3, which is installed on the device body 1. A water storage cavity 311 is formed inside the water tank assembly 3, and the water storage cavity 311 is connected to the drain port 21.

[0075] Specifically, the cooking equipment 100 also includes a water tank assembly 3, which is installed on the equipment body 1. The water tank assembly 3 forms a water storage cavity 311. The water storage cavity 311 can be selectively connected to the drain port 21. That is, the user can separate the water tank assembly 3 from the equipment body 1 to disconnect the water storage cavity 311 from the drain port 21, or the user can install the water tank assembly 3 on the equipment body 1 to connect the water storage cavity 311 to the drain port 21. When the water tank assembly 3 is installed on the equipment body 1, the water tank assembly 3 is located above the steam generator 2, and the bottom of the water storage cavity 311 can be connected to the drain port 21.

[0076] Users can store water in the water storage chamber 311. When the water storage chamber 311 is installed above the drain port 21, the water in the water storage chamber 311 gathers at the bottom of the water storage chamber 311 under the action of gravity. When the water storage chamber 311 is connected to the drain port 21, the water can flow to the drain port 21 under the action of gravity. The drain port 21 is connected to the vaporization chamber 23, so that when the amount of water entering the connecting chamber 27 reaches a certain level, it can flow into the vaporization chamber 23, and then be heated and evaporated in the vaporization chamber 23 to provide steam to the cooking chamber 11, ensuring the taste of the food. Installing the water storage chamber 311 above the drain port 21 can ensure that the water flows to the steam generator 2 by gravity, while also shortening the vertical distance between the water tank assembly 3 and the vaporization chamber 23, thereby reducing the space occupied by the steam generator 2 and improving the lightweight of the cooking equipment 100.

[0077] In some embodiments, the water tank assembly 3 includes a water tank 31 and a shield 32. A water inlet 312 is formed at the bottom of the water tank 31. The shield 32 is movably installed at the water inlet 312. The water inlet 312 is adapted to extend to the drain outlet 21. A push-opening member 211 is provided at the drain outlet 21. The push-opening member 211 is used to push open the shield 32 so that the water inlet 312 communicates with the drain outlet 21.

[0078] Specifically, such as Figure 2 As shown, the water tank assembly 3 includes a water tank 31 and a shield 32. The water tank 31 contains a water storage chamber 311 for storing water. The bottom of the water tank 31 has a downward-facing, open water inlet 312. The shield 32 is movably connected to the water inlet 312, meaning it can move relative to the water inlet 312. During this movement, the shield 32 can open or close the water inlet 312. Furthermore, the drain outlet 21 has a push-opening member 211. The push-opening member 211 can be a cylindrical structure protruding towards the side away from the drain outlet 21, allowing it to push open the shield 32 to open the water inlet 312. The drain outlet 21 also has a sealing member 34. Figure 2 As shown, the sealing element 34 can be constructed as a silicone ring, etc. The sealing element 34 is pressed against the outer peripheral wall of the water inlet 312 to achieve the sealing between the water inlet 312 and the drain port 21.

[0079] During installation, the water inlet 312 of the water tank assembly 3 is extended to the drain port 21, and the top opening member 211 pushes the blocking member 32 upward, so that the water inlet 312 can be connected to the drain port 21. In this way, the water in the water tank 31 flows into the connecting cavity 27 through the water inlet 312 to supply water to the connecting cavity 27. The blocking member 32 is provided with an elastic member 33, which is a spring or the like. The spring can apply an elastic force to the blocking member 32 toward the top opening member 211, so that when the water tank assembly 3 is removed, the blocking member 32 of the water tank assembly 3 separates from the top opening member 211. The top opening member 211 does not apply force to the blocking member 32. Under the action of the elastic force, the blocking member 32 moves toward the top opening member 211 to close the water inlet 312. The operation is simple and convenient.

[0080] In some embodiments, the steam generator 2 is further provided with a drain pipe 26, the inlet end 261 of the drain pipe extending into the bottom region inside the vaporization chamber 23, and the outlet end 262 of the drain pipe communicating with the outside of the vaporization chamber 23.

[0081] Specifically, the steam generator 2 is also provided with a drain pipe 26, which is connected to the vaporization chamber 23 and is used to discharge water from the vaporization chamber 23. The drain pipe 26 passes through the side wall of the vaporization chamber 23, with the inlet end 261 of the drain pipe extending to the bottom area inside the vaporization chamber 23 and the outlet end 262 of the drain pipe located outside the vaporization chamber 23. In the vertical direction, the height of the outlet end 262 of the drain pipe is lower than the height of the inlet end 261 of the drain pipe, and there is a highest position between the inlet end 261 and the outlet end 262 of the drain pipe. The highest position of the drain pipe 26 is higher than the inlet end 261 and the outlet end 262 of the drain pipe.

[0082] The drain pipe 26 is designed in this way to create a height difference between its two ends, allowing water to flow from the inlet end 261 to the outlet end 262 of the drain pipe, thus achieving one-way drainage. As water is discharged, a negative pressure is created inside the drain pipe 26, and water in the vaporization chamber 23 is continuously drawn into the drain pipe 26 for continuous drainage, thereby continuously pumping water through the siphon principle.

[0083] Furthermore, during long-term use of the steam generator 2, scale is prone to form. Water and cleaning agent can be introduced into the vaporization chamber 23 of the steam generator 2 through the drain port 21. The vaporization chamber 23 is heated so that the cleaning agent can quickly dissolve the scale in the vaporization chamber 23. Then, a large amount of water is introduced into the connecting chamber 27 and the vaporization chamber 23 to dilute the dissolved wastewater. When the water level exceeds the highest position of the drain pipe 26, the wastewater in the vaporization chamber 23 can be discharged sequentially through the inlet end 261 of the drain pipe, the highest position of the drain pipe 26, and the outlet end 262 of the drain pipe. The wastewater is then continuously pumped out through the siphon principle until the wastewater in the vaporization chamber 23 is completely discharged.

[0084] Therefore, by setting a drain pipe 26 with a siphon principle in the vaporization chamber 23, the water after scale removal is discharged from the vaporization chamber 23 through the drain pipe 26, thus achieving scale removal and sewage discharge in the vaporization chamber 23. Continuous drainage is achieved through the siphon principle, reducing the need for structures such as water pumps and installation steps. Its structure is simple, easy to operate, and has good performance. Furthermore, regular scale removal and sewage discharge make the steam generator 2 operate efficiently and safely, reducing maintenance frequency and costs, and extending the service life of the steam generator 2.

[0085] The water tank assembly 3 is connected to the drain port 21, which is spaced apart from the vent 221. Air can enter the vent chamber 22 through the vent 221, and water can enter the connecting flow channel 24 through the connecting cavity 27, and then enter the vaporization chamber 23. As the water level rises, water... Figure 3 As shown, the water flow can seal the connecting outlet 242 and the discharge port 21. As the water in the vaporization chamber 23 evaporates, the water storage chamber 311 can continuously replenish water to the vaporization chamber 23 through the discharge port 21 and the connecting channel 24, so that the water level is maintained at the height of the closed connecting channel 24 and the discharge port 21.

[0086] Furthermore, as the water in the vaporization chamber 23 evaporates, the water levels in the connecting chamber 27 and the connecting channel 24 both drop, causing the discharge port 21 to open. Figure 4 As shown, at this time, air can enter through the vent chamber 22, causing the water in the water storage chamber 311 to flow downwards to continue water supply. Even after all the water at the drain port 21 has been supplied, the water in the vaporization chamber 23 continues to evaporate through heating, causing the water level in the vaporization chamber 23 to drop. However, the water in the connecting chamber 27 and the connecting channel 24 remains flush with the connecting outlet 242. Figure 5 As shown, this can isolate the vaporization chamber 23 from the connecting chamber 27, preventing steam from being ejected through the vent 221 or causing damage to the water tank assembly 3, thus ensuring the safety of the cooking equipment 100 and the service life of the water tank assembly 3.

[0087] It should also be noted that when the water level in the vaporization chamber 23 is higher than the inlet end 261 of the drain pipe, the steam generated in the vaporization chamber 23 enters the steam channel 25 through the inlet end 251 of the steam channel for steam transport. When the water level in the vaporization chamber 23 is lower than the inlet end 261 of the drain pipe, the steam in the vaporization chamber 23 can be output simultaneously through the outlet end 252 of the steam channel and the outlet end 262 of the drain pipe.

[0088] In some embodiments, the steam generator 2 includes a first heating element 4, which is connected to the bottom of the vaporization chamber 23 and is used to heat the vaporization chamber 23.

[0089] Specifically, the first heating element 4 can be configured as a heating tube, and the first heating element 4 is detachably connected to the bottom of the vaporization chamber 23, such as... Figure 9 As shown, the steam generator 2 includes an upper shell 291 and a bottom plate 292. The upper shell 291 and the bottom plate 292 are connected to define a vaporization chamber 23. A sealing ring 293 is connected between the upper shell 291 and the bottom plate 292. The sealing ring 293 can be made of silicone or other materials to improve the sealing performance of the connection and ensure that water does not leak. A steam channel 25 and a drain pipe 26 can be connected to the side of the upper shell 291 away from the water tank 31. In this way, when the steam generator 2 is working, after the connecting channel 24 supplies water to the vaporization chamber 23, the first heating element 4 starts to heat the water in the vaporization chamber 23 until steam is generated. This realizes the steam generation of the steam generator 2. Its arrangement is simple and compact, which is conducive to the arrangement of the steam generator 2 in the mounting cavity 12.

[0090] Furthermore, when the steam generator 2 is performing descaling and sewage discharge, the first heating element 4 can heat the cleaning agent in the vaporization chamber 23 so that the cleaning agent can quickly dissolve the scale in the vaporization chamber 23 and improve the descaling and sewage discharge efficiency of the steam generator 2.

[0091] It should be noted that, for example Figure 9 As shown, the steam generator 2 is equipped with a thermostat 6, which includes a fuse and a temperature sensor. When the cooking equipment 100 tilts or causes the vaporization chamber 23 to dry-burn, the temperature sensor can monitor the internal temperature of the steam generator 2, thereby causing the fuse to disconnect the circuit. This protects the circuit safety of the steam generator 2, prevents the electrical components from overheating, and protects the safety of the cooking equipment 100, ensuring that it operates within a safe temperature range.

[0092] In some embodiments, the cooking device 100 further includes a hot air assembly 5, which includes a second heating element 51 and a heating fan 52, the heating fan 52 being used to drive the airflow at the second heating element 51 toward the cooking chamber 11.

[0093] Specifically, the cooking equipment 100 is equipped with a hot air assembly 5. The hot air assembly 5 heats the food in the cooking cavity 11 by delivering hot air, thereby improving the healthiness of the food and meeting different usage needs. The hot air assembly 5 is equipped with a second heating element 51 and a heating fan 52, and both the second heating element 51 and the heating fan 52 are installed in the mounting cavity 12. The second heating element 51 can be constructed as a heating tube or the like, and is used to heat the airflow. The heating fan 52 can drive the hot airflow to move.

[0094] The heating fan 52 is also connected to the drive unit 7, which can be configured as a drive motor, etc. Driven by the drive unit 7, the heating fan 52 can drive the hot airflow near the heating tube to flow, and deliver the hot airflow to the cooking chamber 11. Through continuous hot air circulation, the food is cooked.

[0095] Furthermore, the drive unit 7 is also connected to a cooling fan 71, which is coaxially connected to the heating fan 52. The drive unit 7 drives the cooling fan 71 to rotate, thereby driving the flow of hot air to achieve functions such as heat dissipation. In addition, the hot air assembly 5 can work with the steam generator 2 to deliver steam into the cooking cavity 11, thereby reducing the problem of dry food surface and improving the taste of food.

[0096] In some embodiments, the hot air assembly 5 and the steam generator 2 are spaced apart in the mounting cavity 12, and the steam generator 2 is distributed in the side region of the mounting cavity 12, and both the hot air assembly 5 and the steam generator 2 are located on the upper side of the cooking cavity 11.

[0097] Specifically, the hot air assembly 5 is detachably connected to the mounting cavity 12. The hot air assembly 5 and the steam generator 2 are spaced apart to avoid interference between them and to facilitate individual disassembly and maintenance of the hot air assembly 5 and the steam generator 2. For example, Figure 6 As shown, the hot air assembly 5 is located in the central region of the mounting cavity 12, the steam generator 2 is located in the side region of the mounting cavity 12, and both the hot air assembly 5 and the steam generator 2 are located on the upper side of the cooking cavity 11.

[0098] Furthermore, the hot air assembly 5 heats the food by driving hot airflow. The hot air assembly 5 is set in the middle area of ​​the mounting cavity 12, which allows the hot air assembly 5 to cover a large area of ​​the upper part of the cooking cavity 11. This facilitates the hot air assembly 5 to drive a large amount of hot airflow to circulate between the cooking cavity 11 and the mounting cavity 12 in the vertical direction, thereby improving the heating efficiency and cooking effect of the food. The steam generator 2 is located in the side area of ​​the mounting cavity 12 and supplies water to the vaporization cavity 23 through the water storage cavity 311. After the vaporization cavity 23 generates steam, it flows to the cooking cavity 11 through the steam channel 25, which can replenish the water of the food and ensure the taste of the food.

[0099] Therefore, according to the different functional requirements of the cooking equipment 100, the hot air assembly 5 and the steam generator 2 are reasonably arranged in the space of the installation cavity 12, resulting in a compact structure and complete functions.
