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. Water is generally pumped into the steam generator, which then heats the water to produce steam, which is then introduced into the cooking chamber. However, flow-through steam generators are prone to scale buildup, and in boiler-type steam generators, after scale removal, water cannot drain from the chamber, indicating room for improvement.

[0052] The following is for reference. Figures 1-16 The cooking device 100 according to an embodiment of this utility model, through the cooperation of the top rod assembly 9 and the floating member 8, allows the floating member 8 to open the water inlet passage 22, enabling a large amount of water to be introduced into the vaporization chamber 21 for descaling. A drain pipe 3 is installed in the vaporization chamber 21 to discharge the water used for descaling. Its structure is simple, easy to operate, and has good performance. Furthermore, regular descaling and drainage 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 surface drying out when heated by hot air and improving the taste of the food.

[0053] like Figures 1-16As shown, a cooking device 100 according to an embodiment of the present invention includes: a device body 1, a steam generator 2, a floating member 8, and a top rod assembly 9.

[0054] 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.

[0055] The steam generator 2 is installed inside the equipment body 1. A vaporization chamber 21 is formed inside the steam generator 2. The vaporization chamber 21 is connected to the water inlet flow path 22, and the vaporization chamber 21 is connected to the cooking chamber 12 through the steam flow path 23.

[0056] 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.

[0057] The vaporization chamber 21 is connected to a drain pipe 3, which can discharge water from the vaporization chamber 21. 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 point 36 of the drain pipe is higher than the inlet end 34 and the outlet end 35 of the drain pipe.

[0058] Specifically, such as Figure 3As shown, the drain pipe 3 passes through the side wall of the vaporization chamber 21, with the inlet end 34 of the drain pipe extending to the bottom area inside the vaporization chamber 21 and the outlet end 35 of the drain pipe located outside the vaporization chamber 21. In the vertical direction, the height of the outlet end 35 of the drain pipe is lower than the height of the inlet end 34 of the drain pipe, and there is a highest position between the inlet end 34 and the outlet end of the drain pipe. The highest position 36 of the drain pipe is higher than the inlet end 34 and the outlet end 35 of the drain pipe. This arrangement of the drain pipe 3 can create a height difference between the two ends of the drain pipe 3, allowing water to flow from the inlet end 34 to the outlet end of the drain pipe, realizing one-way drainage of the drain pipe 3. As the water is discharged, a negative pressure is formed inside the drain pipe 3, and the water in the vaporization chamber 21 will be continuously drawn into the drain pipe 3 for continuous drainage, so as to continuously pump water through the siphon principle.

[0059] The floating element 8 is floatingly disposed in the water inlet flow path 22, and the floating element 8 is used 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 to close the water inlet flow path 22 when the water volume is greater than the set water volume.

[0060] 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.

[0061] Furthermore, when there is no water in the water inlet flow path 22, the floating member 8 opens the water inlet flow path 22, allowing 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 is greater than 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.

[0062] 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 6-9 A schematic diagram showing the water supply from the inlet flow path 22 to the vaporization chamber 21.

[0063] The push rod assembly 9 is adapted to selectively press against the floating member 8, and the push rod assembly 9 is used to push the floating member 8 to open the water inlet flow path 22. That is, by selectively pressing the push rod assembly 9 against the floating member 8, the floating member 8 can be moved relative to the water inlet flow path 22, thereby enabling the floating member 8 to open or close the water inlet flow path 22.

[0064] Specifically, the floating component 8 is subject to the buoyancy of the water. By manually operating the push rod assembly 9 to move in the direction of the floating component 8, the push rod assembly 9 can apply a thrust to the floating component 8 in the same direction as its weight. The floating component 8 will move in the direction relative to the cut-off of the water inlet flow path 22, which can open the water inlet flow path 22. In this way, the water inlet flow path 22 can supply water to the vaporization chamber 21.

[0065] Furthermore, when the water in the vaporization chamber 21 reaches a certain height, the force applied to the push rod assembly 9 can be manually removed, causing the floating component 8 to move in the opposite direction under the action of buoyancy, which can close the water inlet flow path 22. In this way, the water in the vaporization chamber 21 can be discharged from the drain pipe 3.

[0066] 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 flow path 22. The vaporization chamber 21 is heated so that the cleaning agent can quickly dissolve the scale in the vaporization chamber 21. By pushing the push rod assembly 9 to open the water inlet flow path 22, a large amount of water is introduced into the vaporization chamber 21 through the water inlet flow path 22 to dilute the dissolved wastewater. Finally, the wastewater is discharged through the drain pipe 3.

[0067] Therefore, by cooperating with the top rod assembly 9 and the floating component 8, a large amount of water can be introduced into the vaporization chamber 21. A drain pipe 3 with a siphon principle is installed in the vaporization chamber 21, through which the water after scale removal is discharged from the vaporization chamber 21, achieving descaling and drainage 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 provides good performance. Furthermore, regular descaling and drainage ensures efficient and safe operation of the steam generator 2, reducing maintenance frequency and costs, and extending its service life. 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 and improving the food's texture.

[0068] In some embodiments, the push rod assembly 9 includes a push rod 91 and an elastic member 92. The push rod 91 is movably mounted on the device body 1 and is adapted to press against the floating member 8. The elastic member 92 is used to apply an elastic force to the push rod 91 in a direction away from the floating member 8.

[0069] Specifically, the push rod 91 extends in the direction toward the floating member 8 and is detachably connected to the equipment body 1 and can move relative to the equipment body 1. Its movement can be linear. The elastic member 92 elastically presses against the push rod 91 and can apply an elastic force to the push rod 91.

[0070] Furthermore, the end of the push rod 91 away from the floating member 8 is the operating end, which can push the end of the push rod 91 to move the push rod 91 toward the floating member 8. The push rod 91 pushes the floating member 8 to move away from the push rod 91, which can open the water inlet passage 22. At the same time, the push rod 91 squeezes the elastic member 92, which increases the compression of the elastic member 92. The elastic member 92 applies an elastic force to the push rod 91 away from the floating member 8. When one end of the push rod 91 is not compressed, the push rod 91 moves away from the floating member 8 under the elastic force of the elastic member 92, and the floating member 8 can be reset under the action of buoyancy.

[0071] Therefore, by setting the cooperation between the push rod 91 and the elastic element 92, the push rod 91 can automatically reset without pushing the floating element 8 to open the water inlet flow path 22. The reset of the push rod 91 facilitates the next operation. The structure is simple, the operation is convenient, and the cost is low.

[0072] In some embodiments, the device body 1 is provided with an outwardly open pressing port 13, one end of the push rod 91 extends into the water inlet channel 22 and presses against the floating member 8, and the other end of the push rod 91 extends to the pressing port 13 and is exposed outwardly.

[0073] Specifically, such as Figure 5 As shown, the pressing port 13 penetrates through the equipment body 1 and is open to the outside for the installation of the push rod 91. The diameter of the pressing port 13 is larger than the external dimensions of the push rod 91, which facilitates the installation of the push rod 91. The pressing port 13 is connected to the water inlet flow path 22. The pressing port 13 and at least part of the structure of the floating member 8 are relatively distributed, which facilitates the push rod 91 pressing against the floating member 8. During installation, one end of the push rod 91 is extended into the water inlet flow path 22, and the other end is located in the pressing port 13 and exposed outside the equipment body 1. A gap can be set between the push rod 91 and the floating member 8 to keep the push rod 91 and the floating member 8 in a separated state. The structure is simple and the installation is convenient.

[0074] Furthermore, the push rod 91 of the pressing port 13 is small in size. The user can operate the push rod 91 with other tools such as a push rod, and push the push rod 91 to move in the direction of the floating member 8 so that one end of the push rod 91 presses against the floating member 8, thereby pushing the floating member 8 to open the water inlet passage 22.

[0075] Therefore, by setting the other end of the push rod 91 to be exposed outward at the pressing port 13, the user can operate the push rod 91 simply and conveniently.

[0076] In some embodiments, the elastic element 92 is sleeved outside the push rod 91 and located inside the pressing port 13. Specifically, the elastic element 92 can be a spring with a certain elasticity, which can provide elastic force to the push rod 91. During installation, the spring is first sleeved on one end of the push rod 91 and then placed inside the pressing port 13, which can realize the installation of the push rod 91, the spring and the device body 1. Its structure is simple and easy to install. Thus, when the push rod 91 is pushed to move, the spring is subjected to the pressure of the push rod 91, and the spring will apply a reverse elastic force to the push rod 91 to realize the spring pushing the push rod 91 to move.

[0077] In some embodiments, the inner end of the pressing port 13 forms a limiting stop surface 131, the outer end peripheral wall of the pressing port 13 is provided with a limiting member 14, the outer peripheral wall of the other end of the push rod 91 is provided with a limiting part 911, the limiting part 911 is provided between the limiting member 14 and one end of the elastic member 92, and the other end of the elastic member 92 abuts against the limiting stop surface 131.

[0078] Specifically, the pressing port 13 can be constructed as a circular hole, and the push rod 91 can be constructed as a circular rod, and as... Figure 5 As shown, a step is formed at the inner end of the pressing port 13, which can be formed as a limiting stop surface 131. The outer peripheral wall of the pressing port 13 is connected to a limiting member 14. The limiting member 14 and the limiting stop surface 131 define an installation space. The outer peripheral wall of the other end of the push rod 91 is provided with a limiting part 911. The limiting part 911 protrudes from the outer surface of the push rod 91. During installation, the elastic member 92 is sleeved on the outside of the push rod 91, and one end of the elastic member 92 abuts against the side of the limiting part 911 near the floating member 8. The push rod 91 is extended to the pressing port 13 so that the other end of the elastic member 92 abuts against the limiting stop surface 131. Then the limiting member 14 is connected to the inner peripheral wall of the outer end of the pressing port 13. The push rod 91 and the elastic member 92 can be installed at the pressing port 13. The structure is simple and the installation is convenient.

[0079] The limiting member 14 is detachably connected to the inner peripheral wall of the pressing port 13, which facilitates installation and disassembly. The limiting part 911 can be integrally formed with the push rod 91, which has a simple structure and is easy to process.

[0080] Therefore, through the above-mentioned arrangement, when the push rod 91 is pushed to move towards the floating member 8, the elastic member 92 presses against the limiting part 911 and the limiting stop surface 131 respectively, which allows the elastic member 92 to store force, and allows the elastic member 92 to push the push rod 91 to move away from the floating member 8. When the limiting part 911 and the limiting member 14 press against each other, the movement of the push rod 91 can be restricted, which can prevent the push rod 91 from separating from the equipment body 1, so that the push rod 91 can be accurately reset.

[0081] In some embodiments, the pressing port 13 is located on the top of the device body 1, which allows the push rod assembly 9 to be installed from the top of the device body 1. The pressing port 13 is completely exposed on the top of the device body 1, which facilitates installation and disassembly. There are no other structures above the pressing port 13, so it will not interfere with other structures of the cooking device 100. It is also convenient for manual operation of the push rod assembly 9. Furthermore, setting the pressing port 13 on the top of the device body 1 makes processing simpler and more convenient, and it is easier to process it in existing cooking devices 100, which facilitates the integration of the push rod assembly 9 with existing cooking devices 100.

[0082] 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 has a water inlet, and the lower water outlet area 226 is connected to the vaporization chamber 21.

[0083] Specifically, such as Figure 3 As shown, an inlet is formed at the upper end of the upper water inlet area 225. This inlet is the inlet end 221 of the water inlet flow path. Through the inlet, the upper water inlet area 225 can be connected to the water source, so that the water source can enter the water inlet flow path 22, as shown. 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 through the flow passage 223, so that the water in the lower water outlet area 226 flows to the vaporization chamber 21, thereby realizing the water supply from the water inlet flow path 22 to the vaporization chamber 21.

[0084] 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.

[0085] 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 floatingly disposed in the lower water outlet area 226 and is used to open or close the cut-off port 227.

[0086] Specifically, a cut-off point 227 is provided between the upper water inlet area 225 and the lower water outlet area 226. For example, the cut-off point 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 4As 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. That is, the floating member 8 can float up and down in the lower water outlet area 226. 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.

[0087] Therefore, as Figure 6 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 7 As 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.

[0088] 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-off opening 227 and guides and cooperates with the inner wall of the cut-off opening 227.

[0089] 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.

[0090] Furthermore, the main body 82 is located within the lower water outlet area 226 and is used to close the cut-off port 227, and the push rod assembly 9 is adapted to press against the main body 82.

[0091] Specifically, such as Figure 4 As shown, the main body 82 has a top mating surface 821 on the side near the guide portion 81, and the device body 1 has a bottom mating surface 228 on the outer periphery of the cut-off port 227. When the main body 82 can move with the floating member 8 in the lower water outlet area 226, the top mating surface 821 and the bottom mating surface 228 can be made to fit or separate, so as to open or close the cut-off port 227. Furthermore, the push rod assembly 9 presses against the main body 82, that is, the push rod 91 of the push rod assembly 9 can press against the top mating surface 821, so as to separate the top mating surface 821 from the bottom mating surface 228, thereby separating the floating member 8 from the cut-off port 227 and opening the cut-off port 227.

[0092] Therefore, by setting the guide part 81 and the cut-off port 227 to guide each other, after the push rod assembly 9 pushes the floating part 8 to move, the floating part 8 will always be in a guiding state with the cut-off port 227, so that the floating part 8 moves stably and reliably during 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.

[0093] In some embodiments, a raised platform 229 protruding toward the cut-off port 227 is provided in the lower water outlet area 226. The main body 82 is movable between the raised platform 229 and the cut-off port 227, and the top rod assembly 9 and the raised platform 229 are distributed opposite each other in the direction of movement of the main body 82.

[0094] Specifically, such as Figure 4 As shown, the raised platform 229 protrudes from the bottom wall of the lower water outlet area 226 toward the cut-off port 227, and the raised platform 229 and the cut-off port 227 are distributed opposite to 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. The floating member 8 is installed between the two. The floating member 8 is installed between the raised platform 229 and the cut-off port 227 in the vertical direction. During installation, at least a portion of the guide portion 81 of the floating member 8 is extended into the cut-off port 227, and the main body portion 82 of the floating member 8 is located between the raised platform 229 and the cut-off port 227 to realize the installation of the floating member 8.

[0095] Furthermore, the main body 82 can move vertically, meaning the push rod assembly 9 can be positioned directly opposite the raised platform 229 in the vertical direction. In this way, the push rod assembly 9 can push the floating member 8 to move along the direction of movement of the floating member 8, thereby opening or closing the cutting port 227. The structure is simple, easy to process, and convenient to assemble and disassemble.

[0096] 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 floating member 8 and 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.

[0097] Furthermore, the distance between the end face of the raised platform 229 and the cut-off port 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-off port 227, ensuring that the floating member 8 can effectively close or open the cut-off port 227, thereby improving the water supply efficiency of the water inlet flow path 22 toward the vaporization chamber 21.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] Specifically, such as Figure 3 As 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.

[0106] 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.

[0107] 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, the height of the gap being h, and satisfying: 2mm≤h≤5mm.

[0108] 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 3As 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 height of 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.

[0109] 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.

[0110] In some embodiments, the height of the inlet end 221 of the water inlet path is higher than or equal to the height of the highest position 36 of the drain pipe. That is, the height of the inlet end 221 of the water inlet path can be equal to the height of the highest position 36 of the drain pipe, or the height of the inlet end 221 of the water inlet path 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.

[0111] In this embodiment, as Figure 3 As shown, the height of the inlet end 221 of the water inlet flow path 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 at the inlet end 221 of the water inlet flow path, enabling more water to flow 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 flows 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.

[0112] In other embodiments, the height of the inlet end 231 of the steam flow path is higher than the height of the inlet end 221 of the water flow path, in the vertical direction, such as... Figure 3As shown, the inlet end 221 of the water inlet path is located between the inlet end 231 of the steam inlet 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 end 221 of the water inlet path, and the water level in the vaporization chamber 21 is lower than the inlet end 231 of the steam inlet path. This prevents water from entering the inlet end 231 of the steam inlet path, thus preventing water from being discharged through the steam inlet 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 inlet path 23 and contaminating the steam inlet path 23, or causing blockage of the steam inlet path 23. Thus, the descaling and sewage discharge of the vaporization chamber 21 can be satisfied, and the safety of the steam inlet path 23 can also be guaranteed.

[0113] 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 passage 22.

[0114] Specifically, water tank assembly 4 is used for water storage, such as Figure 1 , Figure 2 , Figure 6 and Figure 14 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 from the inlet end 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 421, which can be opened directly to add water.

[0115] 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.

[0116] 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 inlet end 221 of the water inlet path.

[0117] Specifically, such as Figure 3 and Figure 14As 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.

[0118] Among them, such as Figure 14 As shown, the blocking component 42 includes a valve 421, a push rod 422, and an elastic reset component 423. The elastic reset 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.

[0119] 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.

[0120] 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 15 and Figure 16 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.

[0121] 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.

[0122] And, such as Figures 10-13 As shown, when cleaning scale, a cleaning agent, such as citric acid, is first added to the water tank assembly 4. Water is then supplied to the vaporization chamber 21 through the water tank assembly 4, maintaining a certain liquid level in the vaporization chamber 21. The descaling process is then performed, with the citric acid dissolving the scale to form a relatively concentrated liquid. The push rod assembly 9 is then manually pushed against the floating part 8, causing the floating part 8 to open the water inlet flow path 22, allowing the water inlet flow path 22 to supply water to the vaporization chamber 21. This dilutes the water concentration in the vaporization chamber 21 until the liquid level exceeds the highest position of the drain pipe 3. Water will then be discharged from the drain pipe 3, forming a siphon effect to continue pumping water from the vaporization chamber 21 until the liquid level is lower than the lower end of the drain pipe 3, thus completing the descaling and drainage of the vaporization chamber 21.

[0123] It should be noted that, for example Figure 15 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.

[0124] 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.

[0125] 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 16 As shown, 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 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 cavity 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] Among them, such as Figure 16 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.

[0130] The second heating element 51 and the heating fan 52 are installed in the mounting cavity 11 of the equipment body 1.
