Description

Technical Field

[0001] This utility model relates to the field of household appliances technology, and in particular to a cooking device. Background Technology

[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, existing air fryers require water from the tank to be pumped into the vaporization chamber via a water pump or other equipment to provide steam to the cooking chamber. The water pump makes the steam generator complex and costly. Alternatively, the water tank and vaporization chamber can be vertically distributed, allowing water to flow into the vaporization chamber under gravity. However, this arrangement results in a large vertical space occupied by the steam generation system, which affects the lightweight design of the air fryer and leaves room for improvement.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] The following is for reference. Figures 1-9 The cooking device 100 according to the present invention has a simple structure, which can reduce the installation cost and reduce the space occupied by the steam generator 2, thereby improving the lightweight of the cooking device 100.

[0039] like Figures 1-9 As shown, a cooking device 100 according to an embodiment of the present invention includes: a device body 1, a steam generator 2, and a water tank assembly 3.

[0040] The equipment body 1 has a cooking chamber 11. A steam generator 2 is installed inside the equipment body 1. A transition chamber 21 and a vaporization chamber 23 are formed inside the steam generator 2. The transition chamber 21 and the vaporization chamber 23 are distributed in a horizontal direction and are connected at the bottom. The vaporization chamber 23 is connected to the cooking chamber 11 through a steam channel 25. A water tank assembly 3 is installed inside the equipment body 1. A water storage chamber 311 is formed inside the water tank assembly 3. The transition chamber 21 is located below the water storage chamber 311 and is selectively connected to the bottom of the water storage chamber 311.

[0041] 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.

[0042] 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.

[0043] Furthermore, the cooking device 100 is also equipped with a steam generator 2, which can be used to evaporate water into steam to replenish the moisture of food, prevent the food from becoming too dry, and improve the taste of the food. The steam generator 2 has a vaporization chamber 23 and a transition chamber 21. The transition chamber 21 and the vaporization chamber 23 are distributed in the horizontal direction, and the bottom of the transition chamber 21 and the bottom of the vaporization chamber 23 are connected. That is, water can flow from the bottom of the transition chamber 21 to the bottom of the vaporization chamber 23, which can shorten the vertical space occupied by the steam generator 2. The steam generator 2 is also equipped with a steam channel 25. One end of the steam channel 25 is connected to the vaporization chamber 23, and the other end is open towards the cooking chamber 11, so that the water in the vaporization chamber 23 can flow into the cooking chamber 11 through the steam channel 25 after evaporation, thereby replenishing the moisture of the food and ensuring the taste of the food.

[0044] Furthermore, 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, which can be selectively connected to the transition cavity 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 transition cavity 21, or the user can install the water tank assembly 3 on the equipment body 1 to connect the water storage cavity 311 with the transition cavity 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 top of the transition cavity 21.

[0045] Users can store water in the water storage chamber 311. When the water storage chamber 311 is installed above the transition chamber 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 transition chamber 21, the water can flow into the transition chamber 21 under the action of gravity. The bottom of the transition chamber 21 is connected to the bottom of the vaporization chamber 23, so that when the amount of water entering the transition chamber 21 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 transition chamber 21 and supplying water to the vaporization chamber 23 through the transition chamber 21 can ensure that the water flows into 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, improving the weight of the cooking equipment 100, and the transition chamber 21 has a simple structure, which can reduce the installation cost.

[0046] According to the embodiment of the present invention, the cooking device 100 is provided with a transition cavity 21 that is horizontally connected to the vaporization cavity 23, and the lower part of the water storage cavity 311 is selectively connected to the upper part of the transition cavity 21. This shortens the vertical distance between the water storage cavity 311 and the vaporization cavity 23, thereby reducing the space occupied by the steam generator 2, improving the lightweight of the cooking device 100, and the transition cavity 21 has a simple structure, which can reduce the installation cost, improve the performance, and broaden the applicability.

[0047] In some embodiments, a venting cavity 22 is also formed inside the steam generator 2. The venting cavity 22 is connected between the transition cavity 21 and the vaporization cavity 23, and the venting cavity 22 is provided with a vent 222 that communicates with the outside.

[0048] Specifically, such as Figures 1-2 As shown, a venting chamber 22 is also formed inside the steam generator 2. The venting chamber 22 is located between the transition chamber 21 and the vaporization chamber 23, and the lower part of the venting chamber 22 can communicate with the lower part of the transition chamber 21 and the vaporization chamber 23. The venting chamber 22 is provided with a vent 222, which is located in the upper part of the venting chamber 22. The venting chamber 22 can communicate with the outside through the vent 222, so that outside air can enter the venting chamber 22 through the vent 222.

[0049] When the water tank assembly 3 supplies water to the transition chamber 21, outside air can enter the vent 22 through the vent 222 and then enter the water storage chamber 311 to ensure pressure balance in the water storage chamber 311 and thus ensure normal water supply to the water storage chamber 311. When the water level rises, the outlet end 213 of the transition chamber can be sealed. At this time, the water in the vaporization chamber 23 continues to evaporate, causing the water level in the lower part of the vent 22 and the vaporization chamber 23 to drop. This allows air to enter the transition chamber 21 again through the lower end of the transition chamber 21 and then enter the water storage chamber 311, allowing water to continue flowing into the vaporization chamber 23 and ensuring reliable water supply.

[0050] In some embodiments, the ventilated cavity 22 includes an upper ventilated region 221 and a lower connected region 223. The transition cavity 21, the upper ventilated region 221 and the vaporization cavity 23 are distributed sequentially in the horizontal direction, and the bottom of the transition cavity 21, the bottom of the upper ventilated region 221 and the bottom of the vaporization cavity 23 are all connected through the lower connected region 223.

[0051] Specifically, the venting chamber 22 is located between the transition chamber 21 and the vaporization chamber 23, and as follows: Figure 2As shown, the venting cavity 22 is provided with an upper venting area 221 and a lower connecting area 223. The upper venting area 221 is connected above the lower connecting area 223. The transition cavity 21, the upper venting area 221 and the vaporization cavity 23 are distributed sequentially in the horizontal direction, which can shorten the vertical dimension of the steam generator 2 and improve the weight reduction of the cooking equipment 100. The transition cavity 21, the upper venting area 221 and the vaporization cavity 23 are spaced apart. The outlet end 213 of the transition cavity is located below the transition cavity 21. The outlet end 213 of the transition cavity, the bottom of the upper venting area 221 and the bottom of the vaporization cavity 23 are all connected through the lower connecting area 223.

[0052] Furthermore, the upper venting area 221 is provided with a vent 222, which can supply air to the venting chamber 22. The outlet end 213 of the transition chamber, the bottom of the upper venting area 221 and the bottom of the vaporization chamber 23 are all connected through the lower connecting area 223, so that the water in the transition chamber 21 can flow to the lower connecting area 223 and the vaporization chamber 23 under the action of gravity. The upper venting area 221 can be connected to the transition chamber 21 through the lower connecting area 223 to supply air, ensuring the reliability of water supply to the transition chamber 21.

[0053] In some embodiments, the vent 222 is located at the top of the upper vent area 221, such as... Figure 2 As shown, the venting cavity 22 is provided with an upper venting area 221 and a lower connecting area 223. The upper venting area 221 is located above the lower connecting area 223, and the vent 222 is located at the top of the upper venting area 221, that is, the vent 222 is located at the top of the venting cavity 22. The vent 222 can be flush with the inlet end 211 of the transition cavity. Water will gather below the steam generator 2 under the action of gravity. Setting the vent 222 at the top of the upper venting area 221 can ensure the communication between the vent 222 and the outside world, thereby ensuring the reliability of the air supply from the vent 222 to the water storage cavity 311, so as to ensure the continuous water supply from the water storage cavity 311 to the vaporization cavity 23, and to prevent water from flowing out of the vent 222 to the outside world, thus ensuring the user experience.

[0054] In some embodiments, at least a portion of the water storage cavity 311, the transition cavity 21, and the lower connecting region 223 are sequentially arranged facing each other in the vertical direction.

[0055] Specifically, when the water tank assembly 3 is installed on the main body, the water tank assembly 3 is located above the steam generator 2, and the bottom of the water storage chamber 311 can communicate with the top of the transition chamber 21, and as... Figures 3-5As shown, at least a portion of the water storage chamber 311, the transition chamber 21, and the lower connecting area 223 are arranged in a vertically aligned manner. That is, when the water storage chamber 311 is connected to the transition chamber 21, the water in the water storage chamber 311 can be directly and vertically directed to the lower connecting area 223, and then flow to the vaporization chamber 23 through the lower connecting area 223, thereby improving the water supply efficiency. Furthermore, the vertically aligned arrangement of at least a portion of the water storage chamber 311, the transition chamber 21, and the lower connecting area 223 can improve the compactness of the water storage chamber 311, the transition chamber 21, and the lower connecting area 223 in the horizontal direction, thereby reducing the space occupied by the installation chamber 12, increasing the space of the cooking chamber 11, ensuring the amount of food cooked at one time, improving the user experience, and also improving the overall lightweight of the cooking equipment 100 and reducing its volume.

[0056] In some embodiments, the venting chamber 22 and the vaporization chamber 23 are connected by a water supply channel 24, the outlet end 241 of the water supply channel is higher than the inlet end 242 of the water supply channel, and both are lower than the outlet end 213 of the transition chamber.

[0057] Specifically, a water replenishment channel 24 is provided between the transition chamber 21 and the vaporization chamber 23. The inlet end 242 of the water replenishment channel is connected to the transition chamber 21, and the outlet end 241 of the water replenishment channel is connected to the vaporization chamber 23. This allows water in the transition chamber 21 to enter the vaporization chamber 23 through the water replenishment channel 24, thereby replenishing the vaporization chamber 23 with water.

[0058] Furthermore, the inlet end 242 of the water replenishment channel is configured to connect with the bottom of the transition chamber 21 through the lower connecting area 223, and the outlet end 241 of the water replenishment channel is configured to be higher than the inlet end 242 of the water replenishment channel. This allows the water in the lower connecting area 223 to enter the vaporization chamber 23 through the outlet end 241 of the water replenishment channel after a certain amount of water has been stored in the lower connecting area 223. Both the outlet end 241 and the inlet end 242 of the water replenishment channel are configured to be lower than the outlet end 213 of the transition chamber. This allows the water replenishment channel 24 to be closed when the water level is at the highest point of the outlet end 241 of the water replenishment channel. This ensures that while the water in the vaporization chamber 23 is converted into steam, the transition chamber 21 needs to replenish water into the vaporization chamber 23 to maintain the balance between the two chambers and ensure operational reliability.

[0059] In some embodiments, the water tank assembly 3 is detachably mounted on the device body 1.

[0060] Specifically, the water tank assembly 3 is provided with a water storage chamber 311, which can be used to store water, such as... Figure 1 and Figures 3-5As shown, the water tank assembly 3 is connected to the equipment body 1 and communicates with the upper part of the transition chamber 21. Thus, after the water tank assembly 3 is connected to the equipment body 1, the water tank assembly 3 can communicate with the water supply channel 24 through the transition chamber 21, and the water supply channel 24 can communicate with the vaporization chamber 23. This allows the water in the water storage chamber 311 to flow from the transition chamber 21 into the water supply channel 24, and then into the vaporization chamber 23, thereby supplying water to the vaporization chamber 23 from the water tank assembly 3. After the water in the water tank assembly 3 is used up, the water tank assembly 3 can be detached from the equipment body 1 and water can be added to the water tank assembly 3. Alternatively, the water tank assembly 3 is provided with a water inlet, which can be opened directly to add water.

[0061] The water tank assembly 3 and the equipment body 1 can be detachably connected by bolts or other connectors, or they can be connected by snap-fit ​​or other means. The connection method is simple and easy to assemble and disassemble.

[0062] 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 inlet end 211 of the transition cavity. A push-opening member 212 is provided at the inlet end 211 of the transition cavity. The push-opening member 212 is used to push open the shield 32 so that the water inlet 312 communicates with the inlet end 211 of the transition cavity.

[0063] Specifically, such as Figure 1 As shown, the water tank assembly 3 includes a water tank 31 and a shielding member 32. The water tank 31 contains a water storage cavity 311 for storing water. The bottom of the water tank 31 has a downward-facing, open water inlet 312. The shielding member 32 is movably connected to the water inlet 312, meaning it can move relative to the water inlet 312. During this movement, the shielding member 32 can open or close the water inlet 312. Furthermore, a push-opening member 212 is provided at the inlet end 211 of the transition cavity. The push-opening member 212 can be configured as a cylindrical structure and protrude towards the side away from the transition cavity 21, allowing it to push open the shielding member 32 to open the water inlet 312. A sealing member 34 is also provided at the inlet end 211 of the transition cavity. Figure 9 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 inlet end 211 of the transition cavity.

[0064] During installation, the water inlet 312 of the water tank assembly 3 is extended to the inlet end 211 of the transition cavity, and the opening member 212 pushes the blocking member 32 upward, so that the water inlet 312 can be connected to the inlet end 211 of the transition cavity. In this way, the water in the water tank 31 flows into the transition cavity 21 through the water inlet 312 to supply water to the transition cavity 21. 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 opening member 212, so that when the water tank assembly 3 is removed, the blocking member 32 of the water tank assembly 3 separates from the opening member 212. The opening member 212 does not apply force to the blocking member 32. Under the action of the elastic force, the blocking member 32 moves toward the opening member 212 to close the water inlet 312. The operation is simple and convenient.

[0065] In some embodiments, the transition cavity 21 is provided with a communication port communicating with the vaporization cavity 23. The top opening member 212 and the communication port are both provided on the bottom wall of the transition cavity 21, and the top opening member 212 is located in the middle of the bottom wall of the transition cavity 21. The communication port and the top opening member 212 are distributed at intervals.

[0066] Specifically, the water tank assembly 3 is detachably installed at the inlet end 211 of the transition cavity, and the top opening member 212 provided at the inlet end 211 of the transition cavity can push the blocking member 32 away from the water inlet 312, thereby opening the water inlet 312, so that the water in the water storage cavity 311 can flow into the transition cavity 21. The transition cavity 21 is provided with a connecting port, which is connected to the lower connecting area 223, and can then be connected to the vaporization cavity 23. The connecting port is located on the bottom wall of the transition cavity 21, so that the water flowing into the transition cavity 21 can flow into the lower connecting area 223 under the action of gravity, ensuring the reliability of water supply.

[0067] Furthermore, the top opening member 212 is also provided on the bottom wall of the transition cavity 21. The lower end of the top opening member 212 is connected to the bottom wall of the transition cavity 21, and the upper end can extend vertically upward, so that the top opening member 212 can cooperate with the water tank assembly 3 at the inlet end 211 of the transition cavity. The top opening member 212 is provided in the middle of the bottom wall of the transition cavity 21, and the connecting port is spaced apart from the top opening member 212, which can prevent the water tank assembly 3 from blocking the connecting port, ensuring the reliability of water supply, and allowing the water inlet 312 to supply water around the top opening member 212, thereby improving the water supply speed.

[0068] In some embodiments, the steam generator 2 includes a drain pipe 26, with the inlet end 261 of the drain pipe extending into the bottom region of the vaporization chamber 23 and the outlet end 262 of the drain pipe communicating with the outside of the vaporization chamber 23.

[0069] Specifically, the steam generator 2 is also equipped with a drain pipe 26, which is connected to the vaporization chamber 23 and used to drain water from the vaporization chamber 23. The drain pipe 26 passes through the side wall of the vaporization chamber 23, with its inlet end 261 extending to the bottom area inside the vaporization chamber 23 and its outlet end 262 located outside the vaporization chamber 23. In the vertical direction, the height of the outlet end 262 is lower than the height of the inlet end 261, and the inlet end 261 and outlet end of the drain pipe are... The drain pipe 26 has a highest position between 262 and 261. The highest position of the drain pipe 26 is higher than the inlet end 261 and the outlet end 262 of the drain pipe. This arrangement of the drain pipe 26 creates a height difference between the 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 of the drain pipe 26. As water is discharged, a negative pressure is formed 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.

[0070] 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 water inlet. 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 transition chamber 21 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.

[0071] 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.

[0072] The water tank assembly 3 is connected to the inlet end 211 of the transition chamber. The inlet end 211 of the transition chamber is spaced apart from the vent 222. Air can enter the vent 22 through the vent 222, and water can enter the water supply channel 24 through the transition chamber 21, and then enter the vaporization chamber 23. As the water level rises, water... Figure 3As shown, the water flow can seal the water supply channel 24 and the outlet end 213 of the transition chamber. As the water in the vaporization chamber 23 evaporates, the water storage chamber 311 can continuously supply water to the vaporization chamber 23 through the transition chamber 21 and the water supply channel 24, so that the water level is maintained at the height of the sealed water supply channel 24 and the outlet end 213 of the transition chamber.

[0073] Furthermore, as the water in the vaporization chamber 23 evaporates, the water level in the lower connecting area 223 of the venting chamber 22, the venting chamber 22, and the water replenishment channel 24 all decrease, causing the outlet end 213 of the transition chamber to open, such as... Figure 4 As shown, at this time, air can enter through the venting chamber 22, causing the water in the transition chamber 21 to flow downwards to continue water supply. Even after all the water in the water tank 31 and the transition chamber 21 is 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 lower connecting area 223 of the venting chamber 22 and the water supply channel 24 remains flush with the outlet end of the water supply channel 24. Figure 5 As shown, the vaporization chamber 23 can be isolated from the vent chamber 22 and the transition chamber 21, preventing steam from being ejected through the vent 222 or damaging the water tank assembly 3, thus ensuring the safety of the cooking equipment 100 and the service life of the water tank assembly 3.

[0074] 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.

[0075] 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.

[0076] 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 9As shown, the steam generator 2 includes an upper shell 27 and a bottom plate 28. The upper shell 27 and the bottom plate 28 are connected to define a vaporization chamber 23. A sealing ring 29 is connected between the upper shell 27 and the bottom plate 28. The sealing ring 29 can be made of silicone or other materials to improve the sealing performance of the connection and ensure that water does not leak. The rear side of the upper shell 27 is used to connect the steam channel 25 and the drain pipe 26. In this way, when the steam generator 2 is working, after the water supply 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 enables the steam generator 2 to generate steam. Its arrangement is simple and compact, which is conducive to the arrangement of the steam generator 2 in the mounting cavity 12.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] The heating fan 52 is also connected to the drive unit 7, which can be a drive motor or similar device. Driven by the drive unit 7, the heating fan 52 drives the hot airflow near the heating element, delivering the hot airflow to the cooking chamber 11. Through continuous hot air circulation, the food is cooked. 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, driving the hot airflow to achieve heat dissipation. Furthermore, the hot air assembly 5 can work with the steam generator 2 to deliver steam to the cooking chamber 11, thereby reducing the problem of dry food surfaces and improving the texture of the food.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.
