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] Current air fryers use a motor to drive fan blades that rotate at high speed within the cooking chamber. This generates high-speed hot air, which, under the influence of a heating element, creates efficient convection heat exchange with the food, enabling rapid cooking. However, this high-speed hot air also removes moisture from the surface and interior of the food, resulting in a drier texture.

[0003] To address this dry fuel issue, existing products typically add a steam generator system. This usually involves a water pump drawing water into the steam generator, which then heats the water to produce steam, which is then introduced into the cooking cavity. This makes the steam system complex, bulky, and expensive, leaving room for improvement. Utility Model Content

[0034] The following is for reference. Figures 1-5The cooking device 100 according to an embodiment of the present invention, by setting a water inlet pipe 31 and a steam outlet pipe 32 between the liquid storage chamber 412 and the water inlet chamber 22, allows the liquid storage chamber 412 to continuously replenish water to the water inlet chamber 22 and the vaporization chamber 21 through the water inlet pipe 31, so as to continuously provide steam to the cooking chamber 12. This can keep the food at a certain humidity, which can effectively solve the problem of the food being too dry and dry, and make the food taste better. Compared with supplying water to the vaporization chamber 21 through a water pump, the structure used in this embodiment is simpler, smaller in size, lower in cost, and has better performance.

[0035] like Figures 1-5 As shown, a cooking device 100 according to an embodiment of the present invention includes: a device body 1, a steam generator 2, a water tank assembly 4, a water inlet pipe 31, and a steam outlet pipe 32.

[0036] The device body 1 has a cooking cavity 12 formed inside it. Specifically, the cooking device 100 can be an air fryer, a steam oven, or a grill, or other types. The device body 1 is the shell structure of the cooking device 100, and its interior includes the cooking cavity 12. The cooking cavity 12 has a large cavity space and is used to place the food to be cooked. The hot airflow and steam from the cooking device 100 flow into the cooking cavity 12 to achieve the cooking of the food.

[0037] The steam generator 2 is installed on the equipment body 1. The steam generator 2 has a water inlet chamber 22 and a vaporization chamber 21. The water inlet chamber 2222 is connected to the vaporization chamber 21. The vaporization chamber 21 is connected to the cooking chamber 12 through the steam pipe 23.

[0038] Specifically, the steam generator 2 is used to generate steam for steaming food. The steam generator 2 is detachably connected to the main body 1 of the equipment. The steam generator 2 has a water inlet chamber 22 and a vaporization chamber 21. The water inlet chamber 22 is used to store a certain amount of water and is connected to the vaporization chamber 21. The water inlet chamber 22 is also connected to an external water source to supply water to the vaporization chamber 21. A steam pipe 23 is provided between the vaporization chamber 21 and the cooking chamber 12. In this way, the water in the vaporization chamber 21 is heated to form steam. The steam enters the cooking chamber 12 through the steam pipe 23 to form a complete steam delivery path. Through continuous steam delivery, food is steamed. Alternatively, by delivering steam to the cooking chamber 12, the moisture content of the food in the cooking chamber 12 is increased to prevent the food from drying out, thereby improving the taste of the food and improving the user experience.

[0039] The water tank assembly 4 has a liquid storage chamber 412. The liquid storage chamber 412 is connected to the water inlet chamber 22 through the water inlet pipe 31 to allow water to enter the water inlet chamber 22. The water inlet chamber 22 is connected to the liquid storage chamber 412 through the air outlet pipe 32 to allow air to be released from the liquid storage chamber 412.

[0040] Specifically, the water tank assembly 4 includes a water tank 41, within which a liquid storage chamber 412 is formed. The liquid storage chamber 412 is used to store water. The water tank assembly 4 is connected to the equipment body 1, which allows for the fixation of the water tank assembly 4. Furthermore, one end of the liquid storage chamber 412 of the water tank assembly 4 is connected to the water inlet pipe 31, and the other end is connected to the water inlet chamber 22. In this way, the water in the liquid storage chamber 412 first flows into the water inlet pipe 31 and then flows into the water inlet chamber 22, enabling the water tank assembly 4 to supply water to the water inlet chamber 22. The water inlet chamber 22 is also connected to the vaporization chamber 21, thereby enabling the supply of water to the vaporization chamber 21.

[0041] The water tank assembly 4 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.

[0042] The air outlet pipe 32 is used to circulate air. One end of the air outlet pipe 32 is connected to the water inlet chamber 22, and the other end is connected to the liquid storage chamber 412. In this way, the gas in the water inlet chamber 22 can enter the air outlet pipe 32 and enter the liquid storage chamber 412 through the air outlet pipe 32, so that the gas can be discharged into the liquid storage chamber 412.

[0043] Furthermore, during the process of water tank assembly 4 supplying water to vaporization chamber 21, as the water level in inlet chamber 22 rises, compressed air enters storage chamber 412 through air outlet pipe 32. This gradually reduces the pressure in inlet chamber 22 and gradually increases the pressure in storage chamber 412, thereby enabling water tank assembly 4 to continuously supply water to inlet chamber 22. After the water in cooking chamber 12 decreases due to evaporation, water inlet chamber 22 supplies water to vaporization chamber 21. At this time, the water in inlet chamber 22 decreases, and the air in inlet chamber 22 enters storage chamber 412 through air outlet pipe 32. Simultaneously, the water in storage chamber 412 adds water to inlet chamber 22 through inlet pipe 31, thereby ensuring sufficient water volume in inlet chamber 22 and vaporization chamber 21.

[0044] Therefore, by simultaneously providing a water inlet chamber 22 and a vaporization chamber 21 within the steam generator 2, the overall water storage capacity of the steam generator 2 can be increased. Furthermore, while the water in the vaporization chamber 21 is in use, the liquid storage chamber 412 can continuously replenish water to the water inlet chamber 22 and the vaporization chamber 21 through the water inlet pipe 31, ensuring the operational reliability of the vaporization chamber 21, preventing the vaporization chamber 21 from burning dry and causing damage to the steam generator 2, extending the service life of the steam generator 2, and ensuring the reliability of the cooking equipment 100 and improving the safety of the cooking equipment 100.

[0045] According to the cooking device 100 of this utility model embodiment, by setting an inlet pipe 31 and an outlet pipe 32 between the liquid storage chamber 412 and the water inlet chamber 22, the liquid storage chamber 412 can continuously replenish water to the water inlet chamber 22 and the vaporization chamber 21 through the inlet pipe 31, so as to continuously provide steam to the cooking chamber 12, which can keep the food at a certain humidity, effectively solving the problem of the food being too dry and dry, thus making the food taste better. Compared with supplying water to the vaporization chamber 21 through a water pump, the structure used in this embodiment is simpler, smaller in size, lower in cost, and has better performance.

[0046] In some embodiments, the cooking device 100 further includes an exhaust pipe 33, the outlet end 332 of which is connected to the water inlet chamber 22, and the inlet end 331 of which is connected to the outside of the device body 1.

[0047] Specifically, such as Figure 3 As shown, an exhaust pipe 33 is connected to the water inlet chamber 22 and is also connected to the outside of the equipment body 1, allowing external air to enter the water inlet chamber 22 through the exhaust pipe 33. In this way, when the water level in the water inlet chamber 22 is low, the air in the exhaust pipe 33 can enter the water inlet chamber 22, and the gas in the water inlet chamber 22 can enter the liquid storage chamber 412, and the water in the liquid storage chamber 412 can flow smoothly to the water inlet chamber 22.

[0048] The steam generator 2 can be installed at the rear of the cooking equipment 100. The exhaust pipe 33 is used to circulate air. The exhaust pipe 33 passes through the equipment body 1, and the inlet end 331 of the exhaust pipe is connected to the outside of the equipment body 1. The outlet end 332 of the exhaust pipe is connected to the water inlet chamber 22, which can realize the connection between the water inlet chamber 22 and the outside of the equipment body 1. It can allow air to be exchanged between the water inlet chamber 22 and the outside, and can achieve the function of ventilation. Ventilation can prevent negative pressure from forming inside the pipe and the chamber, thereby maintaining air pressure balance and ensuring smooth liquid flow.

[0049] Furthermore, the liquid storage chamber 412 is in a closed state, meaning that the liquid storage chamber 412 is not connected to the outside of the equipment body 1. This prevents water in the water inlet chamber 22 from entering the exhaust pipe 33, thereby avoiding water leakage at the inlet end 331 of the exhaust pipe.

[0050] In some embodiments, the inlet end 331 of the exhaust pipe is higher than the water inlet chamber 22 and the vaporization chamber 21, i.e. Figure 3As shown in Figure 5, the exhaust pipe 33 extends downward from a position higher than the water inlet chamber 22 and the vaporization chamber 21, and is connected to the water inlet chamber 22. This allows external air to flow downward from a higher position through the exhaust pipe 33 to the water inlet chamber 22, supplementing the water inlet chamber 22 with a certain amount of gas to maintain the water pressure balance within the water inlet chamber 22. Furthermore, the high position of the inlet end 331 of the exhaust pipe increases the length of the exhaust pipe 33, thereby increasing the distance from the inlet end 331 of the exhaust pipe to the water inlet chamber 22. The exhaust pipe 33 can also store a certain amount of air, increasing its gas storage capacity. Moreover, the exhaust pipe 33 can be positioned higher than the steam pipe 23 of the vaporization chamber 21 to separate the two and avoid interference between the gas pipes. This arrangement is reasonable and easy to install.

[0051] In some embodiments, the outlet end 332 of the exhaust pipe is connected to the top of the water inlet chamber 22 and is spaced apart from the water inlet pipe 31 and the exhaust pipe 32.

[0052] Specifically, such as Figure 4 As shown, the outlet end 332 of the exhaust pipe is connected to the top of the water inlet chamber 22, allowing external air to enter the top space of the water inlet chamber 22 through the exhaust pipe 33. The inlet end of the exhaust pipe 32 is also connected to the top of the water inlet chamber 22. Thus, after the air in the exhaust pipe 32 enters the liquid storage chamber 412, the air in the water inlet chamber 22 decreases, and the air in the exhaust pipe 33 enters the water inlet chamber 22, maintaining the gas balance in the water inlet chamber 22. This ensures that the air in the water inlet chamber 22 continuously flows to the liquid storage chamber 412 and prevents negative pressure from appearing in the water inlet chamber 22, allowing the water in the liquid storage chamber 412 to flow smoothly into the water inlet chamber 22.

[0053] The water inlet pipe 31, the air outlet pipe 32, and the exhaust pipe 33 are arranged sequentially and spaced apart in one direction. The water inlet pipe 31 and the air outlet pipe 32 are connected separately to the liquid storage chamber 412. The water inlet pipe 31, the air outlet pipe 32, and the exhaust pipe 33 can all be constructed as flexible pipes. Generally, the water inlet pipe 31 and the air outlet pipe 32 can be set as one pipe, which can realize the supply of water from the liquid storage chamber 412 to the water inlet chamber 22, while the water inlet chamber 22 supplies air to the liquid storage chamber 412. In this embodiment, two pipes are set to realize the water supply and air supply respectively. Compared with setting a single pipe, the diameter of a single pipe can be reduced, which is conducive to the connection and cooperation with the steam generator 2 and can maintain the overall structural coordination.

[0054] Furthermore, the water inlet pipe 31, the air outlet pipe 32, and the exhaust pipe 33 are set apart, so that the three do not affect each other. This allows for dynamic changes in air pressure between the liquid storage chamber 412 and the water inlet chamber 22, enabling the liquid storage chamber 412 to continuously supply water to the water inlet chamber 22. The structure is simple, easy to install and disassemble, and reduces maintenance costs.

[0055] In some embodiments, the steam generator 2 includes a main structure 26 and a connecting cover 27. The connecting cover 27 is detachably connected to the main structure 26 and together with the main structure 26 defines a water inlet chamber 22 and a vaporization chamber 21. A water inlet pipe 31, a steam outlet pipe 32 and a steam exhaust pipe 33 are respectively connected to the connecting cover 27.

[0056] Specifically, after connecting the connecting cover 27 to the main structure 26, the water inlet chamber 22 and the vaporization chamber 21 are defined, which are used for water supply and water storage of the steam generator 2, respectively. The water inlet pipe 31, the steam outlet pipe 32, and the exhaust pipe 33 are connected to the area of ​​the connecting cover 27 near the water inlet chamber 22, ensuring that the three pipes are connected to the water inlet chamber 22. This also shortens the length of the water inlet pipe 31 and the steam outlet pipe 32 between the water inlet chamber 22 and the liquid storage chamber 412, reducing installation and maintenance costs. Furthermore, connecting the water inlet pipe 31, the steam outlet pipe 32, and the exhaust pipe 33 to the connecting cover 27 ensures a stable and secure connection, guaranteeing the water supply stability of the steam generator 2.

[0057] The connecting cover 27 and the main structure 26 can be detachably connected by bolts or other connectors, or by snap-fit ​​or plug-in connection. The connection method is simple and easy to install and disassemble.

[0058] In some embodiments, the water inlet chamber 22 is provided with a vent 227 that is connected to the water inlet pipe 31 and the air outlet pipe 32 respectively. The vent 227 is also connected to the vaporization chamber 21, so that the water in the water inlet chamber 22 flows to the vaporization chamber 21 through the vent 227. The vent 227 is also connected to the air outlet pipe 32, so that the vent 227 can also discharge the gas in the water inlet chamber 22, avoiding pressure problems caused by gas accumulation or affecting the liquid flow.

[0059] Therefore, by setting a vent 227 in the water inlet chamber 22, the pressure between the water inlet chamber 22 and the liquid storage chamber 412 can be stabilized, and water can be smoothly supplied to the water inlet chamber 22, thereby ensuring the smooth operation and working stability of the steam generator 2.

[0060] The water inlet chamber 22 and the vaporization chamber 21 are connected through the flow passage 223. The inlet end 2231 of the flow passage is connected to the water inlet chamber 22, and the outlet end 2232 of the flow passage is connected to the vaporization chamber 21. The inlet end 2231 of the flow passage is lower than the outlet end 2232 of the flow passage, and the outlet end 2232 of the flow passage is lower than the vent 227.

[0061] Specifically, such as Figure 4As shown, the outlet end of the water inlet chamber 22 is connected to the inlet end 2231 of the flow channel, and the outlet end 2232 of the flow channel is connected to the vaporization chamber 21. The lower end of the flow channel 223 is the inlet end 2231, and the upper end is the outlet end 2232. This design, with the inlet end 2231 lower than the outlet end 2232, creates a height difference, allowing water in the water inlet chamber 22 to flow upwards through the flow channel 223 into the vaporization chamber 21. The flow channel 223 can extend in a straight line or at an angle; in this embodiment, it extends vertically, resulting in a simpler structure and easier manufacturing.

[0062] Furthermore, the outlet end 2232 of the flow channel is lower than the drain port 227, which creates a height difference between the two. This allows the liquid in the storage chamber 412 to flow into the water inlet chamber 22 from the drain port 227. After the liquid in the water inlet chamber 22 accumulates to a certain amount, it will be guided to the vaporization chamber 21 through the flow channel 223, so that the liquid can flow along the set path.

[0063] The exhaust pipe 33 is connected to the vent 227 of the water inlet chamber 22. In this way, after the outside air enters the water inlet chamber 22 along the exhaust pipe 33, the outside air can flow from the vent 227 to the side of the exhaust pipe 32, and some air can enter the liquid storage chamber 412 from the exhaust pipe 32, so that the water in the liquid storage chamber 412 can flow to the water inlet chamber 22. When the water level in the water inlet chamber 22 and the vaporization chamber 21 reaches the position of the vent 227, the air in the exhaust pipe 33 cannot enter the side of the vent 227. That is, the air pressure in the water inlet chamber 22 remains unchanged, and the liquid storage chamber 412 stops supplying water to the water inlet pipe 31, and the water in the water inlet pipe 31 stops supplying water to the vaporization chamber 21, so as to realize the quantitative water supply to the vaporization chamber 21. Furthermore, when the water in the vaporization chamber 21 decreases, the water inlet pipe 31 supplies water to the vaporization chamber 21, and the water level in the water inlet pipe 31 drops, which allows the vent 227 to connect with the exhaust pipe 33. In this way, the air in the exhaust pipe 33 can enter the liquid storage chamber 412, and the liquid storage chamber 412 can replenish water to the water inlet pipe 31 to maintain sufficient water volume in the water inlet chamber 22.

[0064] Therefore, through the above settings, the changes in liquid level in the water inlet chamber 22 and vaporization chamber 21, as well as the changes in air pressure in the water inlet chamber 22, can be used to continuously supply water to the vaporization chamber 21. The settings are simple, the water supply process is automatic and reliable, and the dry burning of the vaporization chamber 21 can be avoided, resulting in higher safety.

[0065] In some embodiments, the vaporization chamber 21 is connected to the flow channel 223 through an intermediate flow channel 225. The inlet end of the intermediate flow channel 225 is connected to the flow channel 223, and the outlet end of the intermediate flow channel 225 is connected to the vaporization chamber 21. The intermediate flow channel 225 is higher than the flow channel 223.

[0066] Specifically, a flow channel 223 is connected to the vaporization chamber 21 via an intermediate flow channel 225, allowing water in the flow channel 223 to flow to the intermediate flow channel 225 and then to the vaporization chamber 21, thus supplying water to the vaporization chamber 21. The intermediate flow channel 225 can extend horizontally, and its design is simple and easy to manufacture.

[0067] Furthermore, by setting the intermediate flow channel 225 higher than the inlet end 2231 of the flow channel and the drain port 227 higher than the outlet end 2232 of the flow channel, a U-shaped liquid flow channel can be formed between the water inlet chamber 22 and the vaporization chamber 21. Thus, when there is a liquid level difference between the water inlet chamber 22 and the vaporization chamber 21, and the water level in the water inlet chamber 22 is lower than the drain port 227, the water inlet chamber 22 can continuously supply water to the vaporization chamber 21 through the flow channel 223 and the intermediate flow channel 225 under the influence of the liquid's own gravity and air pressure. This water supply method is simple, reducing the need for pumps and other structures, thereby reducing the installation cost of the steam generator 2.

[0068] In some embodiments, the angle between the line connecting the bottom of the side of the vent 227 near the flow channel 223 and the bottom of the end of the intermediate flow channel 225 away from the flow channel 223 and the horizontal direction is α1, and satisfies: α1≥5°.

[0069] Specifically, such as Figure 4 As shown, there is a height difference between the vent 227 and the intermediate flow channel 225, such that the line connecting the bottom of the vent 227 near the flow channel 223 and the bottom of the intermediate flow channel 225 away from the flow channel 223 forms an angle α1 with the horizontal direction. α1 can be set to values ​​such as 5°, 6°, 7°, 8°, 9°, and 10°. By setting these values, the angle between the line connecting the bottom of the vent 227 near the flow channel 223 and the bottom of the intermediate flow channel 225 away from the flow channel 223, and the horizontal direction, can always be greater than or equal to 5°. Furthermore, the vent 227 is higher than the bottom of the intermediate flow channel 225. Thus, when the device body 1 is tilted relative to the horizontal plane, and the tilt angle is less than or equal to 10°, water in the inlet chamber 22 can still flow smoothly into the vaporization chamber 21. The value of the angle α1 is not limited to those listed in this embodiment and can be selected and set according to actual needs.

[0070] Therefore, through the above settings, the cooking equipment 100 can be placed at a small angle without affecting the water supply to the vaporization chamber 21, and the vaporization chamber 21 can be made to work stably, thereby improving the adaptability of the cooking equipment 100 and its use in different scenarios.

[0071] In other embodiments, the angle between the line connecting the bottom of the inlet end 2231 of the flow channel near the vent 227 and the bottom of the middle flow channel 225 near the vent 227 and the horizontal direction is α2, and satisfies: α2≥5°.

[0072] Specifically, such as Figure 4 As shown, there is a height difference between the inlet end 2231 of the flow channel and the intermediate flow channel 225. This allows the line connecting the bottom of the inlet end 2231 of the flow channel near the vent 227 and the bottom of the intermediate flow channel 225 near the vent 227 to form an angle α2 with the horizontal direction. α2 can be set to 5°, 6°, 7°, 8°, 9°, 10°, etc. By setting these values, the angle between the line connecting the bottom of the inlet end 2231 of the flow channel near the vent 227 and the bottom of the intermediate flow channel 225 near the vent 227 to the horizontal direction can always be greater than or equal to 5°. Furthermore, the bottom of the intermediate flow channel 225 is higher than the inlet end 2231 of the flow channel. Thus, when the equipment body 1 is tilted relative to the horizontal plane, and the tilt angle between the two is less than or equal to 10°, the steam in the vaporization chamber 21 will not enter the flow channel 223, and consequently will not enter the water inlet chamber 22, reducing steam waste. Furthermore, the value of the included angle α2 is not limited to those listed in this embodiment, and can be selected and set according to actual needs.

[0073] Therefore, through the above settings, the cooking device 100 can be placed at a small angle with the cooking device 100 tilted towards the drain port 227 of the water inlet chamber 22, and the drain port 227 can be ensured to be higher than the bottom of the middle flow channel 225. This does not affect the water supply to the vaporization chamber 21, so as to achieve stable operation of the vaporization chamber 21. Water is also kept in the flow channel 223 so that the steam in the cooking chamber 12 will not flow to the water inlet chamber 22 and the liquid storage chamber 412, thereby improving the adaptability of the cooking device 100 and different usage scenarios.

[0074] In some embodiments, the cooking device 100 further includes a first heating element 25, which is disposed at the bottom of the steam generator 2 and is used to heat the vaporization chamber 21.

[0075] Specifically, the first heating element 25 can be configured as a heating tube or a heating base plate, etc., and the first heating element 25 is detachably connected to the bottom of the vaporization chamber 21, such as... Figure 3 and Figure 4As shown, the main structure 26 defines a vaporization chamber 21. A sealing silicone 262 connects the first heating element 25 to the main structure 26, and a sealing silicone 262 also connects the connecting cover 27 to the main structure 26. This improves the sealing of the connection between them to ensure that water does not leak. The main structure 26 is connected to the steam pipe 23. Thus, when the steam generator 2 is working, after the water inlet pipe 31 supplies water to the vaporization chamber 21, the first heating element 25 starts to heat the water in the vaporization chamber 21 until steam is generated. This enables the steam generator 2 to generate steam, and the steam is delivered to the cooking chamber 12 through the steam pipe 23. The arrangement is simple and the structure is compact.

[0076] It should be noted that, for example Figure 5 As shown, the steam generator 2 is equipped with a fuse 28, which can protect the circuit safety of the steam generator 2 and prevent the electrical components from overheating, thereby protecting the safety of the cooking equipment 100. The steam generator 2 is also equipped with a temperature sensor 29, which is used to monitor the internal temperature of the steam generator 2 and ensure that it operates within a safe temperature range.

[0077] In some embodiments, the device body 1 includes a cooking lid 13 and a cooking pot body 14. The cooking lid 13 is connected to the cooking pot body 14 to jointly define a cooking cavity 12. The cooking lid 13 is rotatable relative to the cooking pot body 14 to open or close the cooking cavity 12.

[0078] Specifically, such as Figures 1-3 As shown, the cooking lid 13 is positioned above the cooking pot body 14 and is connected to the cooking pot body 14, together defining the cooking cavity 12 for placing the food to be cooked. The cooking lid 13 is movably connected to the cooking pot body 14, allowing it to move closer to and further away from the cooking pot body 14, thus enabling the cooking cavity 12 to be opened or closed.

[0079] The cooking lid 13 can be rotatably connected to the cooking pot body 14. When the cooking lid 13 moves away from the cooking pot body 14, the cooking cavity 12 can be opened. After opening, the cooking cavity 12 can be opened upwards, allowing the user to place food into or remove food from the cooking cavity 12 through the open opening. After the user completes the operation, the cooking lid 13 can be moved closer to the cooking pot body 14 to close the cooking cavity 12, ensuring that the cooking cavity 12 is sealed from the outside world. This ensures the reliability of the cooking equipment 100 during operation and prevents external contamination of the cooking cavity 12, improving cleanliness.

[0080] Furthermore, it should be noted that the cooking lid 13 can be rotatably connected to the cooking pot body 14 at the rear. The user can operate the cooking lid 13 to rotate upward and backward relative to the cooking pot body 14 to open the cooking cavity 12, and the user can operate the cooking lid 13 to rotate downward and forward relative to the cooking pot body 14 to close the cooking cavity 12. The two can be connected by a hinge to realize the rotatable connection between the cooking lid 13 and the cooking pot body 14. The setup is simple, low-cost, and easy to operate.

[0081] In some embodiments, the water tank assembly 4 is installed on the cooking lid 13, the steam generator 2 is installed on the cooking pot body 14, and the water inlet pipe 31 and the steam outlet pipe 32 are both configured such that one end extends into the cooking lid 13 and the other end extends into the cooking pot body 14.

[0082] Specifically, such as Figure 3 As shown, the water tank assembly 4 is located on the cooking lid 13, and the steam generator 2 is located inside the cooking pot body 14. Both the cooking lid 13 and the steam generator 2 can be located on the rear side of the cooking pot body 14, which simplifies their connection. The steam generator 2 can be located at the bottom of the inner side of the cooking pot body 14. The water inlet pipe 31 and the steam outlet pipe 32 extend vertically. Thus, the upper ends of the water inlet pipe 31 and the steam outlet pipe 32 extend to the cooking lid 13. The water tank 41 of the water tank assembly 4 is provided with a water inlet 411. The water inlet pipe 31 and the steam outlet pipe 32 are connected to the water inlet 411, which connects to the liquid storage chamber 412. The lower ends of the water inlet pipe 31 and the steam outlet pipe 32 extend into the cooking pot body 14 and communicate with the connecting cover 27 of the steam generator 2, which connects to the water inlet chamber 22.

[0083] Thus, with the above configuration, when the cooking lid 13 rotates relative to the cooking pot body 14, the water inlet pipe 31 and the steam outlet pipe 32 will move simultaneously with the rotation of the cooking lid 13. The water inlet pipe 31 is used for water inlet, and the steam outlet pipe 32 is used for air outlet. By setting one water inlet pipe 31 and one steam outlet pipe 32, the size of a single pipe can be reduced, thus not affecting the movement of the hinge, so that the cooking lid 13 can be opened and closed smoothly. At the same time, the diameter of the water inlet pipe 31 and the steam outlet pipe 32 should not be too small to avoid air blockage, so that the gas can pass upward effectively, thereby ensuring that the water flows downward smoothly.

[0084] Furthermore, the steam generator 2 is located on the same side as the rotating connection between the cooking lid 13 and the cooking pot body 14. This reduces the range of motion of the water inlet pipe 31 and the steam outlet pipe 32 when the cooking lid 13 rotates relative to the cooking pot body 14, and also reduces the length of the water inlet pipe 31 and the steam outlet pipe 32, thus improving the overall structural coordination.

[0085] The steam generator 2 is detachably connected to the cooking pot body 14, which facilitates the installation and removal of the steam generator 2, and the water tank assembly 4 is detachably connected to the cooking lid 13, which facilitates the installation and removal of the water tank assembly 4 and the cooking lid 13.

[0086] In some embodiments, one end of the steam pipe 23 is located inside the cooking pot body 14 and communicates with the vaporization chamber 21, the cooking lid 13 is provided with a steam outlet 131 that opens toward the cooking chamber 12, and the other end of the steam pipe 23 extends into the cooking lid 13 and communicates with the steam outlet 131.

[0087] Specifically, such as Figure 3 As shown, the main structure 26 of the steam generator 2 is used to connect the steam pipe 23 on the side near the water inlet chamber 22. The inlet end of the steam pipe 23 extends into the cooking pot body 14 and communicates with the vaporization chamber 21 of the steam generator 2. At least a portion and the outlet end of the steam pipe 23 extend into the cooking lid 13, and the cooking lid 13 is provided with a steam outlet 131. The outlet end of the steam pipe 23 is connected to the steam outlet 131, which can realize the connection and fixation of the steam pipe 23. The steam outlet 131 is open towards the cooking chamber 12, so that the steam pipe 23 can communicate with the cooking chamber 12. Concealing at least a portion of the steam pipe 23 inside the cooking lid 13 can protect the steam pipe 23 and make the inner surface of the cooking lid 13 flat.

[0088] Furthermore, when the steam generator 2 is working, the steam generated in the vaporization chamber 21 is transported to the steam outlet 131 through the steam pipe 23, and steam is sprayed into the cooking chamber 12 from the steam outlet 131 to realize the steam delivery to the cooking chamber 12.

[0089] Furthermore, the steam pipe 23 extends from the cooking pot body 14 into the cooking lid 13, so that when the cooking lid 13 rotates relative to the cooking pot body 14, the steam pipe 23 will move with the rotation of the cooking lid 13. The steam pipe 23 is set in the same way as the water inlet pipe 31 and the steam outlet pipe 32, and the diameter of the steam pipe 23 should not be too large, so that the cooking lid 13 can be opened and closed smoothly, and avoids wear on the steam pipe 23, the water inlet pipe 31 and the steam outlet pipe 32 during the movement of the cooking lid 13, thereby improving the service life of each pipe and improving the performance of the cooking equipment 100.

[0090] In some embodiments, the cooking device 100 further includes a hot air assembly, which includes a second heating element and a heating fan, the heating fan being used to drive airflow at the second heating element toward the cooking chamber 12.

[0091] Specifically, the hot air assembly heats the food inside the cooking chamber 12 by delivering hot air. In this embodiment, the cooking device 100 can have cooking methods such as hot air grilling. The hot air assembly includes a second heating element and a heating fan, which can be disposed inside the cooking cover 13. The second heating element can be constructed as a heating tube for heating the airflow. The heating fan can drive the hot airflow. The heating fan is also connected to a drive motor. Driven by the drive motor, the heating fan drives the hot airflow near the heating tube to flow, delivering the hot airflow to the cooking chamber 12. Through continuous hot air circulation, the food is cooked. Furthermore, the drive motor is also connected to a cooling fan, which is coaxially connected to the drive motor with the heating fan. The drive motor drives the cooling fan to rotate, driving the hot airflow to achieve a heat dissipation function.

[0092] Furthermore, the hot air assembly can work with the steam generator 2 to deliver steam to the cooking cavity 12, which can reduce the problem of dry food surfaces and improve the taste of the food.
