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

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] The following is for reference. Figures 1-10 The cooking device 100 according to an embodiment of the present invention, by setting a floating element 8 in the water inlet flow path 22 to selectively open or close the water inlet flow path 22, can realize the timed and quantitative supply of water to the vaporization chamber 21, so that a certain amount of steam is continuously provided in the vaporization chamber 21 to continuously provide steam to the cooking chamber 12. The steam heats the food, which can keep the food at a certain humidity. Moreover, when the food is baked by hot air, heating the food with an appropriate amount of steam can effectively solve the problem of the food being too dry, so as to make the food taste better. Compared with supplying water to the vaporization chamber 21 by a water pump, the floating element 8 used in this embodiment has a simpler structure, smaller size, lower cost, and better performance.

[0042] like Figures 1-10 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, and a floating component 8.

[0043] The cooking chamber 12 is formed inside the main body of the device. Specifically, the cooking device 100 can be an air fryer, a steam oven, or a grill, or other types. The main body of the device 1 is the shell structure of the cooking device 100, and its interior includes the cooking chamber 12. The cooking chamber 12 has a large cavity space and is used to place the food to be cooked. The hot airflow and steam of the cooking device 100 flow into the cooking chamber 12 to realize the cooking of the food.

[0044] The steam generator 2 is installed inside the equipment body 1. A vaporization chamber 21 is formed inside the steam generator 2. The equipment body 1 is also provided with a water inlet passage 22 and a steam passage 23 that are connected to the vaporization chamber 21. The steam passage 23 is connected to the cooking chamber 12.

[0045] 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. A vaporization chamber 21 is formed inside the steam generator 2. The steam generator 2 is connected to a water inlet path 22 and a steam path 23. One end of the water inlet path 22 is connected to the water inlet of the vaporization chamber 21. One end of the steam path 23 is connected to the steam outlet of the vaporization chamber 21 and the other end is connected to the cooking chamber 12. The other end of the water inlet path 22 is the inlet end 221 of the water inlet path. The water inlet end 221 is connected to an external water source. In this way, the external water source can enter the water inlet path 22 from the inlet end 221 and then enter the vaporization chamber 21. The water is heated in the vaporization chamber 21 to form steam. The steam enters the cooking chamber 12 through the steam path 23. The food is steamed by continuously supplying steam.

[0046] Water tank assembly 4 is adapted to supply water to water inlet flow path 22. Specifically, water tank assembly 4 is used for water storage, such as... Figures 1-3 As shown, the water tank assembly 4 is connected to the inlet end 221 of the water inlet flow path of the equipment body 1. Thus, after the water tank assembly 4 is connected to the equipment body 1, the water tank assembly 4 is connected to the water inlet flow path 22 through the inlet end 221, and the water inlet flow path 22 is connected to the vaporization chamber 21. The water in the water tank assembly 4 flows into the water inlet flow path 22 and the vaporization chamber 21 sequentially from the inlet end 221 of the water inlet flow path, so as to realize the water supply of the water tank assembly 4 to the water inlet flow path 22, and thus to the vaporization chamber 21. After the water in the water tank assembly 4 is used up, the water tank assembly 4 can be removed from the equipment body 1 and water can be added to the water tank assembly 4. Alternatively, the water tank assembly 4 is provided with a water inlet 412, which can be opened directly to add water.

[0047] 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.

[0048] The floating element 8 is movably disposed in the water inlet flow path 22. The floating element 8 is configured to open the water inlet flow path 22 when the water volume in the vaporization chamber 21 is less than the set water volume and close the water inlet flow path 22 when the water volume is greater than the set water volume.

[0049] In other words, the water in the water inlet flow path 22 will generate buoyancy on the floating member 8. According to the change in the amount of water in the vaporization chamber 21, the water will generate different buoyancy on the floating member 8, which will allow the floating member 8 to move relative to the water inlet flow path 22. During the movement of the floating member 8, the water inlet flow path 22 will switch between the open state and the closed state.

[0050] Specifically, the floating component 8 has its own weight. After water flows through the water inlet channel 22, the floating component 8 will be subjected to a certain buoyancy. That is, the difference between the buoyancy and the weight can enable the floating component 8 to move relative to the water inlet channel 22. Furthermore, the water inlet channel 22 is connected to the vaporization chamber 21. The floating component 8 is located between the water inlet channel 22 and the vaporization chamber 21, which can enable the floating component 8 to cut off or connect the water flow state of the water inlet channel 22.

[0051] Furthermore, when there is no water in the water inlet flow path 22, the floating member 8 opens the water inlet flow path 22, connecting the water tank assembly 4 to the water inlet flow path 22. This allows the water inlet flow path 22 to supply water to the vaporization chamber 21. As the liquid level rises to a certain height, when the buoyancy of the water on the floating member 8 exceeds the weight of the floating member 8, the floating member 8 moves relative to the water inlet flow path 22 until the floating member 8 closes the water inlet flow path 22, thus completing the water supply from the water inlet flow path 22 to the vaporization chamber 21.

[0052] As the vaporization chamber 21 continuously generates steam, the water volume within it gradually decreases. When the water volume in the vaporization chamber 21 falls below its set value, the buoyancy force on the floating component 8 becomes less than its own weight, causing it to move in the opposite direction relative to the water inlet path 22. This allows the floating component 8 to open the water inlet path 22, enabling it to continue supplying water to the vaporization chamber 21 until a new equilibrium is reached, at which point the floating component 8 closes the water inlet path 22. For example, Figures 5-8 A schematic diagram showing the water supply from the inlet flow path 22 to the vaporization chamber 21.

[0053] Therefore, the floating component 8 selectively opens or closes the water inlet path 22, enabling timed and quantitative water supply to the vaporization chamber 21, so that a certain amount of steam is continuously supplied to the cooking chamber 12. The steam heats the food, keeping it at a certain level of humidity. When baking food with hot air, heating the food with an appropriate amount of steam can effectively solve the problem of the food being too dry, resulting in a better taste. Compared with supplying water to the vaporization chamber 21 through a water pump, the floating component 8 used in this embodiment has a simpler structure, smaller size, lower cost, and better performance.

[0054] In some embodiments, the water inlet flow path 22 includes an upper water inlet area 225 and a lower water outlet area 226. The upper water inlet area 225 is connected to the water tank assembly 4, and the lower water outlet area 226 is connected to the vaporization chamber 21.

[0055] Specifically, such as Figure 3 As shown, the upper water inlet area 225 is connected to the outlet end of the water tank assembly 4, allowing water in the water tank assembly 4 to flow upwards to the upper water inlet area 225, thereby enabling the water tank assembly 4 to supply water to the water inlet flow path 22. Figure 4 As shown, the upper water inlet area 225 and the lower water outlet area 226 can be vertically connected, so that the water in the upper water inlet area 225 flows downward to the lower water outlet area 226, and the lower water outlet area 226 is connected to the inlet end 211 of the vaporization chamber, so that the water in the lower water outlet area 226 flows to the vaporization chamber 21, so that the water tank assembly 4 supplies water to the vaporization chamber 21 through the water inlet flow path 22.

[0056] This configuration allows for water supply to the vaporization chamber 21, while also storing a certain amount of water in the upper water inlet area 225 and the lower water outlet area 226 of the water inlet flow path 22. This ensures that water is continuously supplied to the vaporization chamber 21 after the water volume in the vaporization chamber 21 decreases, so that the vaporization chamber 21 can stably deliver steam to the cooking chamber 12.

[0057] The upper water inlet area 225 and the lower water outlet area 226 are connected by a cut-off port 227. The floating component 8 is located at the connection between the upper water inlet area 225 and the lower water outlet area 226 and is used to open or close the cut-off port 227.

[0058] Specifically, a cut-off port 227 is provided between the upper water inlet area 225 and the lower water outlet area 226. For example, the cut-off port 227 can be provided in either the upper water inlet area 225 or the lower water outlet area 226. The arrangement is varied and can be flexibly configured according to the specific internal structure of the water inlet flow path 22. In this embodiment, for example… Figure 4 As shown, a cut-off port 227 can be provided at the lower end of the upper water inlet area 225. The cut-off port 227 is open near the lower water outlet area 226, and the floating member 8 is located on the lower side of the cut-off port 227. In this way, the floating member 8 can float up and down relative to the cut-off port 227 under the buoyancy of the water in the lower water outlet area 226, so as to open or close the cut-off port 227, thereby realizing the connection and disconnection between the upper water inlet area 225 and the lower water outlet area 226.

[0059] Therefore, as Figure 5 As shown, when the floating element 8 closes the cut-off port 227, it can limit the water supply path 22 from continuing to supply water to the vaporization chamber 21, thereby achieving a quantitative water supply from the water supply path 22 to the vaporization chamber 21, and as... Figure 6As shown, when the floating part 8 opens the cut-off port 227, the water inlet flow path 22 can supply water to the vaporization chamber 21 in a timely manner so that the water volume in the vaporization chamber 21 is sufficient.

[0060] In some embodiments, a first mating surface 228 is formed in the device body 1, which is distributed around the cut-out 227. The floating member 8 is provided with a second mating surface 821. The second mating surface 821 is adapted to fit with the first mating surface 228 and close the cut-out 227. The cut-out 227 can be opened after the first mating surface 228 and the second mating surface 821 are separated.

[0061] Specifically, such as Figure 4 As shown, the first mating surface 228 is distributed around the cut-out 227. The first mating surface 228 can be constructed as a plane. The floating member 8 is provided with a second mating surface 821, which is distributed around the floating member 8. The second mating surface 821 can also be constructed as a plane. In this way, the second mating surface 821 can be flatly fitted with the first mating surface 228 to avoid water leakage. Furthermore, by arranging the first mating surface 228 around the cut-out 227, the outer periphery of the cut-out 227 can be pressed against the floating member 8. The surface-to-surface contact can improve the sealing performance between the floating member 8 and the cut-out 227. The structure is simple and easy to process.

[0062] Furthermore, the area of ​​the second mating surface 821 can be set to be greater than or equal to the area of ​​the first mating surface 228, so that the second mating surface 821 and the first mating surface 228 can be completely fitted together, so that the floating part 8 and the cut-off port 227 can be reliably sealed, thereby cutting off the upper water inlet area 225 and the lower water outlet area 226.

[0063] The cut-out 227 can be constructed in the shape of a circle, a square, an ellipse, etc. The first mating surface 228 can be the same as or different from the structure of the cut-out 227. Its setting method is diverse and can be selected according to the actual space.

[0064] Therefore, when the floating member 8 moves relative to the cutting port 227, the second mating surface 821 moves closer to or further away from the first mating surface 228 to achieve the closing and opening of the cutting port 227, which can keep the water level in the vaporization chamber 21 within a stable range, so as to ensure the normal operation of the vaporization chamber 21 and reduce the phenomenon of dry burning of the vaporization chamber 21.

[0065] Furthermore, the floating component 8 and the cut-off port 227 can be coordinated by elastic pressing or other means to achieve the closure of the cut-off port 227 by the floating component 8.

[0066] In some embodiments, the floating member 8 includes a guide portion 81 and a main body portion 82 connected together. The outer diameter of the main body portion 82 is larger than the outer diameter of the guide portion 81. The guide portion 81 is inserted into the cut-out 227 and guides and cooperates with the inner wall of the cut-out 227. A second mating surface 821 is formed on the main body portion 82.

[0067] Specifically, both the guide portion 81 and the main body portion 82 can be constructed as cylindrical structures, with the outer diameter of the guide portion 81 being smaller than the outer diameter of the main body portion 82, and the outer diameter of the guide portion 81 being smaller than the inner diameter of the cut-out 227. For example... Figure 4 As shown, relative to the main body 82, the guide part 81 is close to the cut-out 227 and extends into the cut-out 227, so that the guide part 81 can guide and cooperate with the inner wall of the cut-out 227, and the floating part 8 can be guided and cooperated with the cut-out 227. Its structure is simple and easy to process.

[0068] And such as Figure 4 As shown, the second mating surface 821 is formed on the side of the main body 82 near the cut-out 227, that is, the second mating surface 821 is located on the upper side of the main body 82. In this way, when the floating member 8 moves toward the cut-out 227, the second mating surface 821 fits with the first mating surface 228, which can close the cut-out 227. When the floating member 8 moves away from the cut-out 227, the second mating surface 821 separates from the first mating surface 228, which can open the cut-out 227.

[0069] Therefore, by setting the guide part 81 to guide the cut-off port 227, the floating part 8 can always be in a guiding engagement state with the cut-off port 227, so that the floating part 8 is stable and reliable in the up and down floating process, thereby enabling the cut-off port 227 to switch stably between the open state and the closed state, so as to achieve stable water supply to the vaporization chamber 21.

[0070] In some embodiments, the opening area of ​​the cut-off port 227 is s, and the vertical distance between the highest liquid level in the water tank assembly 4 and the cut-off port 227 is h. max The volume of the main body 82 is V, the weight of the floating part 8 is G, and the following condition is satisfied: ρ 水 gh max s≤ρ 水 gV-G.

[0071] Specifically, the opening area of ​​the cut-off port 227 is the interception area of ​​the water passing through the cut-off port 227, and the highest liquid level in the water tank assembly 4 can be understood as the state when the water tank assembly 4 is full of water, and the vertical distance between the highest liquid level of the water tank assembly 4 and the cut-off port 227 is h. max At this time, when the water tank assembly 4 is filled with water between its highest liquid level and the cut-off port 227, the water pressure on the floating component 8 is ρ. 水 gh maxs, and at this time the buoyancy force on the floating component 8 is ρ 水 gV-G, when ρ 水 gh max s≤ρ 水 gV-G means that the buoyancy force on the floating component 8 is greater than the water pressure on the floating component 8, which allows the floating component 8 to be in a closed state with the cut-off opening 227. The buoyancy force on the floating component 8 varies depending on the material, and can be selected according to the actual situation.

[0072] Therefore, with the above settings, when the entire water tank assembly 4 is filled with water, the water pressure generated can be fully supported by the buoyancy of the floating component 8, so that the cut-off port 227 is in a closed state, that is, water will not leak from the water inlet flow path 22 into the vaporization chamber 21. In this way, the amount of water in the vaporization chamber 21 will not be changed, and the vaporization chamber 21 will be prevented from generating a large amount of steam that is transported to the cooking chamber 12, thus affecting the cooking effect of the food.

[0073] In some embodiments, the lower water outlet area 226 and the vaporization chamber 21 are connected by a flow channel 223, the lower end 2232 of the flow channel is connected to the lower water outlet area 226 and the upper end is connected to the vaporization chamber 21.

[0074] Specifically, such as Figure 4 As shown, the outlet end of the lower water outlet region 226 is connected to the lower end 2232 of the flow channel, and the upper end 2231 of the flow channel is connected to the vaporization chamber 21. The lower end 2232 of the flow channel is the inlet end, and the upper end 2231 is the outlet end. This allows water from the lower water outlet region 226 to enter the vaporization chamber 21 through the flow channel 223. The flow channel 223 extends vertically.

[0075] Furthermore, the upper end 2231 of the flow passage is higher than the lowest liquid level of the vaporization chamber 21, which can create a liquid level difference between the vaporization chamber 21 and the flow passage 223. When there is no pressure in the water in the flow passage 223, the water in the flow passage 223 will not enter the vaporization chamber 21. In this way, a water seal feature can be formed at the upper end 2231 of the flow passage, preventing the steam in the vaporization chamber 21 from entering the flow passage 223.

[0076] like Figure 3 and Figure 4As shown, the height of the inlet end 211 of the vaporization chamber is higher than the lowest liquid level of the vaporization chamber 21, and the inner bottom wall of the lower water outlet area 226 can be set to be level with the inner bottom wall of the vaporization chamber 21. In this way, the water in the lower water outlet area 226 can flow upward through the flow channel 223 into the vaporization chamber 21. When the water volume in the vaporization chamber 21 is within a stable range, the liquid level in the lower water outlet area 226 is the same as the liquid level in the vaporization chamber 21. As the water in the vaporization chamber 21 continues to evaporate, and when the water in the water tank assembly 4 and the upper water inlet area 225 is exhausted, the water level in the vaporization chamber 21 will be lower than the upper end 2231 of the flow channel, and the steam will not enter the flow channel 223. The steam will only flow towards the cooking cavity 12, which is safer and has a simple structure and is easy to implement.

[0077] Where the liquid level in the vaporization chamber 21 is at the same height as the upper end 2231 of the flow channel, such as Figure 4 As shown, the floating component 8 closes the cut-off port 227, and at this time, the buoyancy force on the floating component 8 from the water is not greater than the weight of the floating component 8, and the underwater volume of the floating component 8 is set as V1, i.e., ρ 水 With gV1≤G, the floating component 8 is subjected to water pressure from the upper water inlet area 225 at the cut-off port 227, so that the water pressure and gravity on the floating component 8 are greater than the buoyancy on the floating component 8. This allows the floating component 8 to move away from the cut-off port 227, so that the cut-off port 227 opens. The water flow from the upper water inlet area 225 enters the lower water outlet area 226 through the cut-off port 227, and the water flow from the lower water outlet area 226 flows into the vaporization chamber 21 through the flow passage 223, so as to replenish water to the vaporization chamber 21 and avoid the subsequent dry burning problem of the vaporization chamber 21.

[0078] And, such as Figure 7 and Figure 8 As shown, when the water in the water tank assembly 4 and the upper water inlet area 225 is depleted, that is, when the floating part 8 is not subjected to the water pressure of the upper water inlet area 225, that is, the floating part 8 can remain closed with the cut-off port 227, or the floating part 8 can separate from the cut-off port 227. At this time, the upper water inlet area 225 will not supply water to the vaporization chamber 21.

[0079] Therefore, when the liquid level in the vaporization chamber 21 is the same as the height of the upper end 2231 of the flow channel, this is the limit position of the liquid level in the vaporization chamber 21. At this time, water can be added to the vaporization chamber 21, or when the water in the water tank assembly 4 is exhausted, the user is prompted to add water to the water tank assembly 4 so as to realize that the water tank assembly 4 can add water to the vaporization chamber 21 to ensure the normal operation of the vaporization chamber 21. Its setting method is simple and safe.

[0080] In some embodiments, a raised platform 229 is formed in the lower water outlet area 226. The raised platform 229 and the cut-off opening 227 are distributed opposite to each other in the vertical direction, and the raised platform 229 protrudes toward the cut-off opening 227. A portion of the floating member 8 extends into the cut-off opening 227 and another portion is movably disposed between the raised platform 229 and the cut-off opening 227.

[0081] Specifically, such as Figure 4 As shown, the raised platform 229 protrudes from the bottom wall of the lower water outlet area 226 towards the cut-off port 227, and the raised platform 229 and the cut-off port 227 are distributed opposite each other. The cut-off port 227 is located above the raised platform 229, and the center of the raised platform 229 can be directly opposite the center of the cut-off port 227. A floating component 8 is installed between the two. The floating component 8 is installed vertically between the raised platform 229 and the cut-off port 227. During installation, at least a portion of the guide portion 81 of the floating component 8 extends into the cut-off port 227, and the main body portion 82 of the floating component 8 faces the raised platform 229, thus realizing the installation of the floating component 8. The structure is simple, easy to process, and convenient to assemble and disassemble.

[0082] Therefore, by setting the raised platform 229 to protrude towards the cut-out 227, the distance between the raised platform 229 and the cut-out 227 can be reduced. In this way, when the main body 82 is in contact with the raised platform 229, the guide part 81 always maintains a guiding fit with the inner wall of the cut-out 227. As a result, when the floating member 8 moves, the second mating surface 821 of the floating member 8 and the first mating surface 228 of the cut-out 227 can reliably fit or separate, which improves the reliability of the floating member 8 moving between the raised platform 229 and the cut-out 227. Moreover, the relatively distributed arrangement of the raised platform 229 and the cut-out 227 makes it easy to achieve a guiding fit between the floating member 8 and the cut-out 227.

[0083] Among them, the raised platform 229 can be constructed as a circular boss, and the outer diameter of the circular boss can be greater than or equal to the maximum outer diameter of the floating member 8, which can facilitate the smooth contact between the floating member 8 and the circular boss.

[0084] In some embodiments, the distance between the end face of the raised platform 229 and the cut-out 227 is less than the vertical height of the floating member 8. This allows the floating member 8 to move stably between the raised platform 229 and the cut-out 227, ensuring that the floating member 8 can effectively close or open the cut-out 227, thereby improving the water supply efficiency of the water tank assembly 4 toward the vaporization chamber 21.

[0085] Specifically, the raised platform 229 protrudes a certain height from the bottom wall of the lower water outlet area 226 toward the cut-off port 227, which reduces the distance between the raised platform 229 and the cut-off port 227. The distance between the two is less than the vertical height of the floating member 8, that is, the distance between the two is less than the total height of the guide part 81 and the main body 82. In this way, when the main body 82 is attached to or separated from the cut-off port 227, the guide part 81 is always in a guiding and cooperating manner with the cut-off port 227, avoiding the problem of the floating member 8 detaching from the cut-off port 227 and causing the problem of the floating member 8 failing to seal the cut-off port 227. This allows the floating member 8 to move reliably between the raised platform 229 and the cut-off port 227, so that the cut-off port 227 can be stably switched between the closed state and the open state.

[0086] In some embodiments, the water tank assembly 4 includes a water tank 41 and a shield 42. A water inlet 411 is formed at the bottom of the water tank 41. The shield 42 is movably installed at the water inlet 411. The water inlet 411 is adapted to extend to the inlet end 221 of the water inlet path. A push-opening member 222 is provided at the inlet end 221 of the water inlet path. The push-opening member 222 is used to push open the shield 42 so that the water inlet 411 communicates with the water inlet path 22.

[0087] Specifically, such as Figure 3 and Figure 9 As shown, a water storage chamber is formed inside the water tank 41 for storing water. A downward-facing, open water inlet 411 is formed at the bottom of the water tank 41. A blocking member 42 is movably connected to the water inlet 411, meaning the blocking member 42 can move relative to the water inlet 411, and during this movement, the blocking member 42 can open or close the water inlet 411. Furthermore, a top-opening member 222 is provided at the center of the inlet end 221 of the water inlet path, used to apply force to the blocking member 42 to open the water inlet 411. The water inlet 411 is provided with a sealing member 224, such as... Figure 3 As shown, the seal 224 can be constructed as a silicone ring. The seal 224 is pressed against the outer peripheral wall of the water inlet 411 to achieve a seal at the connection between the water inlet 411 and the inlet end 221 of the water inlet flow path.

[0088] During installation, the water inlet 411 of the water tank assembly 4 is extended to the inlet end 221 of the water inlet flow path, and the opening member 222 pushes the blocking member 42 upward to open the blocking member 42, so that the water inlet 411 can be connected to the inlet end 221 of the water inlet flow path. In this way, the water in the water tank 41 flows into the water inlet flow path 22 through the water inlet 411 to supply water to the water inlet flow path 22. When the water tank assembly 4 is removed, the blocking member 42 of the water tank assembly 4 moves away from the opening member 222, and the opening member 222 does not apply force to the blocking member 42. The blocking member 42 moves in the direction of the opening member 222 to close the water inlet 411. The operation is simple and convenient.

[0089] Among them, such as Figure 9As shown, the blocking component 42 includes a valve 421, a push rod 422, and an elastic component 423. The elastic component 423 can be constructed as a spring, which is installed between the valve 421 and the push rod 422. When the water tank assembly 4 is not connected to the equipment body 1, the blocking component 42 presses against the water inlet 411 by gravity to close the water inlet 411. After the water tank assembly 4 is connected to the equipment body 1, the opening component 222 pushes the push rod 422 upward. After the water tank assembly 4 is in contact with the equipment body 1, the opening component 222 opens the water inlet 411 so that the water inlet 411 is connected to the water inlet flow path 22.

[0090] In some embodiments, the steam generator 2 includes a first heating element 25, which is connected to the bottom of the vaporization chamber 21 and is used to heat the vaporization chamber 21.

[0091] Specifically, the first heating element 25 can be configured as a heating tube, and the first heating element 25 is detachably connected to the bottom of the vaporization chamber 21, such as... Figure 3 and Figure 10 As shown, the steam generator 2 includes an outer casing 26 and a base plate 27. The outer casing 26 and the base plate 27 are connected to define a vaporization chamber 21, and as shown... Figure 3 As shown, a sealing silicone 271 is connected between the outer shell 26 and the base plate 27 to improve the sealing of the connection between the two and ensure that water will not leak. The rear side of the outer shell 26 is used to connect the steam flow path 23. In this way, when the steam generator 2 is working, after the water inlet flow path 22 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 flow path 23. The arrangement is simple and the structure is compact.

[0092] It should be noted that, for example Figure 3 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.

[0093] 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 12.

[0094] Specifically, the hot air assembly 5 heats the food inside the cooking cavity 12 by delivering hot air. In this embodiment, the cooking device 100 may have cooking methods such as hot air grilling. Figure 10As shown, the hot air assembly 5 includes a second heating element 51 and a heating fan 52, which are mounted on the device body 1. The second heating element 51 can be configured as a heating tube for heating the airflow. The heating fan 52 can drive the hot airflow. The heating fan 52 is also connected to a drive motor 6. Driven by the drive motor 6, the heating fan 52 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 6 is also connected to a cooling fan 7, which is coaxially connected to the drive motor 6 with the heating fan 52. The drive motor 6 drives the cooling fan 7 to rotate, driving the hot airflow to achieve a heat dissipation function.

[0095] Furthermore, the hot air assembly 5 can work with the steam generator 2 to deliver steam to the cooking cavity 12, which can reduce the problem of dry food surface and improve the taste of food.

[0096] In some embodiments, the device body 1 also has an installation cavity 11 located above the cooking cavity 12. The hot air assembly 5 and the steam generator 2 are spaced apart and distributed in the installation cavity 11. The steam generator 2 is distributed in the side area of ​​the installation cavity 11, and both the hot air assembly 5 and the steam generator 2 are located above the cooking cavity 12.

[0097] Specifically, the device body 1 also includes a mounting cavity 11 for mounting various structures of the cooking device 100. The mounting cavity 11 and the cooking cavity 12 are spaced apart, and the mounting cavity 11 is located above the cooking cavity 12. The hot air assembly 5 and the steam generator 2 are both detachably connected to the mounting cavity 11. The hot air assembly 5 and the steam generator 2 are spaced apart to avoid interference between them, reduce interference with their respective operations, and facilitate individual disassembly and maintenance of the hot air assembly 5 and the steam generator 2.

[0098] Among them, such as Figure 10 As shown, the hot air assembly 5 is located in the middle region of the mounting cavity 11, and the steam generator 2 is located in the side region of the mounting cavity 11. Both the hot air assembly 5 and the steam generator 2 are located above the cooking cavity 12. The hot air assembly 5 heats the food by driving hot airflow. By placing the hot air assembly 5 in the middle region of the mounting cavity 11, the hot air assembly 5 can cover a large area of ​​the upper region of the cooking cavity 12. This facilitates the hot air assembly 5 to drive a large amount of hot airflow to circulate between the cooking cavity 12 and the mounting cavity 11 in the vertical direction, thereby improving the heating efficiency and cooking effect of the food. The steam generator 2 is located in the side region of the mounting cavity 11 and supplies water to the vaporization cavity 21 through the water inlet passage 22. After the vaporization cavity 21 generates steam, it flows downward through the steam passage 23 to the cooking cavity 12, thereby realizing the steaming of food.

[0099] Furthermore, the second heating element 51 and the heating fan 52 are installed in the mounting cavity 11 of the equipment body 1.

[0100] 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 11, resulting in a compact structure and complete functions.
