[0043] The following is for reference.Figures 1-14 The cooking device 100 according to an embodiment of the present invention is described in this article. By setting a drain pipe 3 in the vaporization chamber 21, with the outlet end 35 of the drain pipe lower than the inlet end 34 of the drain pipe, and the highest position 36 of the drain pipe higher than the inlet end 34 and the outlet end 35 of the drain pipe, the drain pipe 3 forms a siphon principle to discharge the water after scale removal from the vaporization chamber 21, thereby achieving scale removal and sewage discharge in the vaporization chamber 21. This makes the operation of the steam generator 2 efficient and safe, and the continuous drainage achieved by the siphon principle reduces the need for water pumps, etc. Its structure is simple, easy to operate, and has good performance.

[0044] like Figures 1-14 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 drain pipe 3.

[0045] The device body 1 has a cooking cavity 12 and a mounting cavity 11. 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 and the mounting cavity 11. The cooking cavity 12 is used to place the food to be cooked, and the mounting cavity 11 is used to install other structures of the cooking device 100. The mounting cavity 11 and the cooking cavity 12 are spaced apart, which can separate the structures in the mounting cavity 11 from the cooking cavity 12.

[0046] The steam generator 2 is installed in the mounting cavity 11. A vaporization cavity 21 is formed in the steam generator 2. The steam generator 2 is connected to a water inlet path 22 and a steam path 23 that are respectively connected to the vaporization cavity 21. The water inlet path 22 has a water inlet 221, and the steam path 23 is connected to the cooking cavity 12.

[0047] Specifically, the steam generator 2 is used to generate steam for steaming food. The steam generator 2 is detachably connected to the mounting cavity 11. A vaporization cavity 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 cavity 21, and one end of the steam path 23 is connected to the steam outlet of the vaporization cavity 21 and the other end is connected to the cooking cavity 12. The other end of the water inlet path 22 is a water inlet 221, which is connected to an external water source. In this way, the external water source can enter the water inlet path 22 from the water inlet 221 and then enter the vaporization cavity 21. The water is heated in the vaporization cavity 21 to form steam. The steam enters the cooking cavity 12 through the steam path 23. Through continuous steam supply, the food is steamed.

[0048] The inlet end 34 of the drain pipe extends to the bottom area inside the vaporization chamber 21, and the outlet end 35 of the drain pipe connects to the outside of the vaporization chamber 21. The outlet end 35 of the drain pipe is lower than the inlet end 34 of the drain pipe, and the highest position 36 of the drain pipe is higher than the inlet end 34 and the outlet end 35 of the drain pipe.

[0049] Specifically, the drain pipe 3 is connected to the vaporization chamber 21 and is used to discharge water from the vaporization chamber 21. The drain pipe 3 passes through the side wall of the vaporization chamber 21, with the inlet end 34 extending to the bottom area inside the vaporization chamber 21 and the outlet end 35 located outside the vaporization chamber 21. In the vertical direction, the height of the outlet end 35 is lower than the height of the inlet end 34, and there is a highest point between the inlet end 34 and the outlet end. The highest point 36 of the drain pipe is higher than both the inlet end 34 and the outlet end 35. This arrangement of the drain pipe 3 creates a height difference between its two ends, allowing water to flow from the inlet end 34 to the outlet end, achieving one-way drainage. As water is discharged, a negative pressure is created inside the drain pipe 3, continuously drawing water from the vaporization chamber 21 into the drain pipe 3 for continuous drainage, thus continuously pumping water through the siphon principle.

[0050] 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 21 of the steam generator 2 through the water inlet channel 22. The vaporization chamber 21 is heated so that the cleaning agent can quickly dissolve the scale in the vaporization chamber 21. Then, a large amount of water is introduced into the water inlet channel 22 and the vaporization chamber 21 to dilute the dissolved wastewater. When the water level exceeds the highest position 36 of the drain pipe, the wastewater in the vaporization chamber 21 can be discharged sequentially through the inlet end 34 of the drain pipe, the highest position 36 of the drain pipe, and the outlet end 35 of the drain pipe. The wastewater is then continuously pumped out through the siphon principle until the wastewater in the vaporization chamber 21 is completely discharged.

[0051] Therefore, by installing a drain pipe 3 with a siphon principle in the vaporization chamber 21, the water after scale removal is discharged from the vaporization chamber 21 through the drain pipe 3, achieving scale removal and sewage discharge of the vaporization chamber 21. Continuous drainage is achieved through the siphon principle, reducing the need for pumps and other structures, simplifying installation steps. Its structure is simple, easy to operate, and performs well. Furthermore, regular scale removal and sewage discharge ensures efficient and safe operation of the steam generator 2, reducing maintenance frequency and costs, and extending the service life of the steam generator 2. Additionally, the steam generator 2 can be used in conjunction with structures such as hot air systems, solving the problem of food surfaces drying out when heated by hot air, thus improving the food's texture.

[0052] In some embodiments, the inlet end 231 of the steam flow path is higher than the highest position 36 of the drain pipe, and the outlet end 232 of the steam flow path is lower than the outlet end 35 of the drain pipe.

[0053] Specifically, such as Figure 3 As shown, in the vertical direction, the inlet end 231 of the steam flow path is located in the upper region of the vaporization chamber 21, and the highest position 36 of the drain pipe is spaced apart from the inlet end 231 of the steam flow path and is lower than the inlet end 231 of the steam flow path. The highest position 36 of the drain pipe is located in the middle region of the vaporization chamber 21. In this way, steam can be transported on the upper side of the vaporization chamber 21, and the drain pipe 3 is installed in the middle region of the vaporization chamber 21. The inlet end 34 of the drain pipe extends to the bottom region of the vaporization chamber 21, which can reduce the amount of steam transported from the drain pipe 3. The outlet end 232 of the steam flow path is connected to the cooking chamber 12, and the outlet end 232 of the steam flow path is lower than the outlet end 35 of the drain pipe. In this way, the arrangement of the drain pipe 3 and the steam flow path 23 can be realized in a limited space, and the overall structure is compact and occupies little space.

[0054] Therefore, by setting up the steam flow path 23 and drain pipe 3, after the steam generator 2 is working, a large amount of steam generated by the vaporization chamber 21 accumulates in the top area of ​​the vaporization chamber 21, and a large amount of steam flows to the cooking chamber 12 through the steam flow path 23, which helps to improve the steam delivery efficiency.

[0055] In some embodiments, the outlet end 35 of the drain pipe is connected to the steam flow path 23 to communicate with the cooking cavity 12, such as... Figure 3 As shown, the outlet end 35 of the drain pipe is connected to the upper area of ​​the outlet end 232 of the steam flow path, which can indirectly realize the connection between the drain pipe 3 and the cooking cavity 12. In this way, when draining, the water in the drain pipe 3 can flow to the cooking cavity 12 through the outlet end 232 of the steam flow path, so as to discharge the water in the drain pipe 3 to the cooking cavity 12, which facilitates the cleaning of water.

[0056] Therefore, by connecting the outlet end 35 of the drain pipe to the steam flow path 23, part of the structure of the steam flow path 23 can be shared with the drain pipe 3, which simplifies the setting of the drain pipe 3, makes the overall structure more compact, and facilitates the installation of the steam generator 2 and the equipment body 1.

[0057] In some embodiments, the drain pipe 3 includes a first pipe section 31, a second pipe section 32, and a third pipe section 33 connected in sequence. The first pipe section 31 is located in the vaporization chamber 21 and extends vertically. The lower end of the first pipe section 31 extends to the bottom of the vaporization chamber 21. The second pipe section 32 passes through the side wall of the vaporization chamber 21 and extends horizontally. One end of the second pipe section 32 is connected to the upper end of the first pipe section 31. At least a portion of the third pipe section 33 extends vertically. The upper end of the third pipe section 33 is connected to the other end of the second pipe section 32. The lower end of the third pipe section 33 communicates with the steam flow path 23.

[0058] Specifically, such as Figure 3As shown, the first pipe section 31, the second pipe section 32, and the third pipe section 33 are connected sequentially along the water flow direction. The first pipe section 31 and the third pipe section 33 are connected to the same side of the second pipe section 32. The first pipe section 31 is located inside the vaporization chamber 21 and extends vertically, allowing water to flow vertically within the first pipe section 31. The lower end of the first pipe section 31 extends to the bottom of the vaporization chamber 21, which facilitates the pumping and discharge of more water from the vaporization chamber 21. The second pipe section 32 is bent relative to the first pipe section 31. The second pipe section 32 is connected to the side wall of the vaporization chamber 21 in a horizontal direction, allowing water to flow horizontally within the second pipe section 32. The third pipe section 33 is bent and connected to the second pipe section 32. At least a portion of the third pipe section 33 extends vertically, and the lower end of the third pipe section 33 is connected to the steam flow path 23, allowing water to flow vertically to the outlet end 232 of the steam flow path. Through the above arrangement, water can be diverted in different directions. The drain pipe 3 can be constructed as a U-shaped pipe.

[0059] Furthermore, the lower end of the third pipe section 33 is lower than the lower end of the first pipe section 31. This arrangement creates a height difference between the ends of the two pipe sections. Under the pressure of the water and atmospheric pressure in the vaporization chamber 21, the water in the vaporization chamber 21 can flow sequentially to the first pipe section 31, the second pipe section 32, and the third pipe section 33, thereby achieving unidirectional drainage of the drain pipe 3 and continuous drainage through the siphon principle.

[0060] In some embodiments, the inlet end 34 of the drain pipe is spaced apart from the bottom wall of the vaporization chamber 21 to form a gap h, and satisfies: 2mm≤h≤5mm.

[0061] Specifically, there is a gap between the inlet end 34 of the drain pipe and the bottom wall of the vaporization chamber 21, such as Figure 3 As shown, the lower end of the first pipe section 31 is spaced apart from the inner bottom wall of the vaporization chamber 21, which facilitates the water in the vaporization chamber 21 to be drawn into the drain pipe 3. The gap can be set to h, and h can be 2mm, 3mm, 4mm, 5mm, etc. By setting the above values, the lower end of the first pipe section 31 can be prevented from contacting the inner bottom wall of the vaporization chamber 21, which makes it easier for the water in the vaporization chamber 21 to flow into the first pipe section 31 through the gap, thereby improving the drainage efficiency of the drain pipe 3.

[0062] The gap cannot be set too large, as an excessively large gap will prevent more water from being discharged from the vaporization chamber 21, affecting the drainage volume of the vaporization chamber 21. Conversely, the gap cannot be set too small, as this will increase the difficulty of water suction. Therefore, by setting the gap to meet the requirement of 2mm≤h≤5mm, the drainage efficiency of the drain pipe 3 can be satisfied, and the drainage volume of the vaporization chamber 21 can also be improved. Furthermore, setting the gap can ensure that the inlet end of the drain pipe 3 will not be blocked due to the accumulation of sediment, allowing sediment or particles to pass through smoothly.

[0063] In some embodiments, the height of the inlet 221 is higher than or equal to the height of the highest position 36 of the drain pipe. That is, the height of the inlet 221 can be equal to the height of the highest position 36 of the drain pipe, or the height of the inlet 221 can be higher than the height of the highest position 36 of the drain pipe. The setting method is not unique and can be flexibly selected according to actual needs.

[0064] In this embodiment, as Figure 3 As shown, the height of the inlet 221 is higher than the height of the highest position 36 of the drain pipe. This allows the water level in the vaporization chamber 21 to rise to the same level as the liquid level in the inlet 221, enabling more water to be introduced into the vaporization chamber 21. Since the water level in the vaporization chamber 21 is higher than the height of the highest position 36 of the drain pipe, the water in the vaporization chamber 21 can flow into the drain pipe 3, filling the drain pipe 3 with water. Furthermore, the height difference between the two ends of the drain pipe 3 enables the siphon effect during the drainage process of the drain pipe 3.

[0065] In other embodiments, the height of the inlet end 231 of the steam flow path is higher than the height of the inlet 221, in the vertical direction, such as... Figure 3 As shown, the inlet 221 is located between the inlet end 231 of the steam flow path and the highest position 36 of the drain pipe. The water level in the vaporization chamber 21 can be raised to the same height as the inlet 221, and the water level in the vaporization chamber 21 is lower than the height of the inlet end 231 of the steam flow path. This prevents water from entering the inlet end 231 of the steam flow path and prevents water from being discharged through the steam flow path 23. In this embodiment, the drain pipe 3 is used to discharge the descaling wastewater in the vaporization chamber 21, thereby preventing the descaling wastewater from entering the steam flow path 23 and contaminating the steam flow path 23, or causing blockage of the steam flow path 23. Thus, the descaling and sewage discharge of the vaporization chamber 21 can be satisfied, and the safety of the steam flow path 23 can also be guaranteed.

[0066] In some embodiments, the water inlet 221 is located on the front side of the equipment body 1, and the steam flow path 23 and the drain pipe 3 are both located on the rear side of the steam generator 2.

[0067] Specifically, such as Figure 3 As shown, the water inlet 221 is located on the front side of the device body 1, allowing the user to perform water addition and other operations from the front side of the device body 1. The water inlet 221 is located on the front side of the steam generator 2, and the steam flow path 23 and the drain pipe 3 are respectively connected to the rear side of the steam generator 2. Thus, when the steam generator 2 is working, water can be added to the steam generator 2 from the front water inlet 221, and steam is transported to the cooking chamber 12 from the rear side of the steam generator 2 through the steam flow path 23. Wastewater is discharged from the rear side of the steam generator 2 through the drain pipe 3. Therefore, through the above arrangement, it is convenient for the user to perform various operations on the cooking device 100 from the front side, improving the user experience.

[0068] In some embodiments, the cooking appliance 100 further includes a water tank assembly 4, which is detachably mounted on the appliance body 1 and is adapted to supply water to the water inlet 221.

[0069] Specifically, water tank assembly 4 is used for water storage, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the water tank assembly 4 is connected to the water inlet 221 of the equipment body 1. After connecting the water tank assembly 4 to the equipment body 1, the water tank assembly 4 is connected to the water inlet flow path 22 through the water inlet 221, and the water inlet flow path 22 is connected to the vaporization chamber 21. The water in the water tank assembly 4 flows from the water inlet 221 into the water inlet flow path 22, and then into the vaporization chamber 21, so as to realize the water supply of the water tank assembly 4 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, which can be opened directly to add water.

[0070] 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.

[0071] 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 water inlet 221. A push-opening member 222 is provided at the water inlet 221. The push-opening member 222 is used to push open the shield 42 so that the water inlet 411 communicates with the water inlet 221.

[0072] Specifically, such as Figure 3 As shown, a water tank 41 has a water storage cavity for storing water. The bottom of the water tank 41 has a downward-facing, open water inlet 411. 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 water inlet 221 to apply force to the blocking member 42 to open the water inlet 411. The water inlet 411 is also equipped with a sealing member 224, such as... Figure 13 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 water outlet 221.

[0073] During installation, the water inlet 411 of the water tank assembly 4 is extended to the water inlet 221, and the top opening member 222 pushes the blocking member 42 upward, so that the water inlet 411 can be connected to the water inlet 221. In this way, the water in the water tank 41 flows into the water inlet 221 through the water inlet 411 to supply water to the water inlet 221. When the water tank assembly 4 is removed, the blocking member 42 of the water tank assembly 4 moves away from the top opening member 222, and the top opening member 222 does not apply force to the blocking member 42. The blocking member 42 moves toward the top opening member 222 to close the water inlet 411. The operation is simple and convenient.

[0074] Among them, such as Figure 4 As 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 attached to 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 221.

[0075] In some embodiments, the steam generator 2 also forms an exhaust flow path 24, one end of which is connected between the inlet 221 and the outlet 223 of the water inlet flow path 22, and the other end of which forms an exhaust port 241. The outlet 223 of the water inlet flow path 22 is lower than the exhaust flow path 24.

[0076] Specifically, such as Figure 3 As shown, one end of the exhaust flow path 24 is connected to the water inlet flow path 22, and the exhaust flow path 24 has an exhaust port 241 at the end away from the water inlet flow path 22. The exhaust port 241 can communicate with the outside air. When the exhaust port 241 is connected to the space outside the equipment body 1, the gas in the exhaust flow path 24 can be discharged to the outside of the equipment body 1. The outlet 223 of the water inlet flow path 22 is lower than the exhaust flow path 24. In this way, the water in the water inlet flow path 22 enters the vaporization chamber 21 through the outlet 223. As the water volume continues to rise, the water enters the exhaust flow path 24 from the connection between the water inlet flow path 22 and the exhaust flow path 24, so that the gas in the exhaust flow path 24 is discharged to the outside.

[0077] When the exhaust port 241 of the exhaust flow path 24 is closed, the gas in the exhaust flow path 24 can enter the water inlet flow path 22, which can control the water flow to continuously add water to the vaporization chamber 21. When the water level reaches the connection between the exhaust flow path 24 and the water inlet flow path 22, the air in the exhaust flow path 24 cannot enter the water inlet flow path 22 nor can it be discharged. In this way, the water supply of the water inlet flow path 22 to the vaporization chamber 21 can be controlled.

[0078] In some embodiments, the upper end of the exhaust flow path 24 is at the same height as the water inlet 221, and the lower end of the exhaust flow path 24 is higher than the water outlet 223 of the water inlet flow path 22.

[0079] Specifically, the upper end of the exhaust flow path 24 is the exhaust port 241, which is at the same height as the inlet 221. The lower end of the exhaust flow path 24 is higher than the outlet 223 of the inlet flow path 22, so that the exhaust flow path 24 and the outlet 223 can form a height difference to adapt to the water flow control at different stages of the inlet flow path 22.

[0080] Among them, such as Figures 5-8 As shown, when the water tank assembly 4 is connected to the water inlet 221, the water inlet 221 is separated from the exhaust port 241, and the water tank assembly 4 can isolate the exhaust port 241 of the exhaust flow path 24 from the outside to keep the air in the exhaust flow path 24 constant. When the water tank assembly 4 supplies water to the water inlet 221, air can enter the water inlet flow path 22 and the water tank assembly 4 from the lower end of the exhaust flow path 24 along the water flow. The water flows into the vaporization chamber 21 at the water outlet 223. As the water volume gradually increases, air cannot enter the water inlet flow path 22 and the water tank assembly 4 in reverse. At this time, the water inlet flow path 22 stops supplying water to the vaporization chamber 21, which can realize the control of the water supply by the exhaust flow path 24. As the water level in the vaporization chamber 21 decreases, water is supplied to the vaporization chamber 21 in a cyclical manner through the above water supply method until the water tank assembly 4 is empty.

[0081] It should also be noted that, such as Figures 5-7 As shown, when the water level in the vaporization chamber 21 is higher than the lower end of the drain pipe 3, the steam generated in the vaporization chamber 21 enters the steam flow path 23 through the inlet end 231 of the steam flow path for steam transport, as... Figure 8 As shown, when the water level in the vaporization chamber 21 is lower than the lower end of the drain pipe 3, the steam in the vaporization chamber 21 can be simultaneously transported through the inlet end 231 of the steam flow path and the lower end of the drain pipe 3.

[0082] And, such as Figures 9-12 As shown, when cleaning scale, first add cleaning agent to the water tank assembly 4. The cleaning agent can be citric acid. Water is supplied to the vaporization chamber 21 through the water tank assembly 4, so that the vaporization chamber 21 maintains a certain liquid level. The descaling process is used to remove scale. Citric acid dissolves scale and forms a relatively concentrated liquid. Remove the water tank assembly 4 and then manually add water to the equipment body 1 quickly through the water inlet 221 to dilute the water concentration in the vaporization chamber 21 until it is full. In this way, the liquid level will be above the highest position of the drain pipe 3. The water will be discharged from the drain pipe 3 and form a siphon principle to continue to pump water from the vaporization chamber 21 until the liquid level is lower than the lower end of the drain pipe 3. The descaling and sewage discharge of the vaporization chamber 21 can be completed.

[0083] 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.

[0084] 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 13 As shown, the steam generator 2 includes an outer shell 26 and a base plate 27. The outer shell 26 and the base plate 27 are connected to define a vaporization chamber 21. A sealing silicone 271 is connected between the outer shell 26 and the base plate 27 to improve the sealing of the connection and ensure that water does not leak. The rear side of the outer shell 26 is used to connect the steam flow path 23 and the drain pipe 3. Thus, 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. Its arrangement is simple and compact, which is conducive to the arrangement of the steam generator 2 in the mounting cavity 11.

[0085] Furthermore, when the steam generator 2 is performing descaling and sewage discharge, the first heating element 25 can heat the cleaning agent in the vaporization chamber 21 so that the cleaning agent can quickly dissolve the scale in the vaporization chamber 21 and improve the descaling and sewage discharge efficiency of the steam generator 2.

[0086] It should be noted that, for example Figure 13 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.

[0087] 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.

[0088] Specifically, the hot air assembly 5 heats the food in the cooking chamber 12 by delivering hot air. In this embodiment, the cooking device 100 may have cooking methods such as hot air grilling. The hot air assembly 5 includes a second heating element 51 and a heating fan 52, which are installed in the mounting cavity 11. 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.

[0089] 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.

[0090] In some embodiments, the hot air assembly 5 and the steam generator 2 are spaced apart in the mounting cavity 11, and the steam generator 2 is distributed in the side region of the mounting cavity 11, and both the hot air assembly 5 and the steam generator 2 are located on the upper side of the cooking cavity 12.

[0091] Specifically, the hot air assembly 5 is 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 and reduce interference with their respective operations. It also facilitates the separate disassembly and maintenance of the hot air assembly 5 and the steam generator 2.

[0092] Among them, such as Figure 14 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 on the upper side of 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 flow path 22. After the vaporization cavity 21 generates steam, it flows downward through the steam flow path 23 to the cooking cavity 12, thereby realizing the steaming of food.

[0093] 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.
