The present application provides a food cooking device, which can cook food by steam heating. For example, the food cooking device can be an electric steamer or a steam oven.

Please refer to Figures 1 and 2. In some embodiments, the food cooking device 1 includes a cooking chamber 100, a steam generator 200, a water tank 300 and other related structures.

The cooking chamber 100 has a cooking cavity 110 for placing food, and the cooking cavity 110 is used as a space for cooking food. The cooking chamber 100 generally has a food access opening 120, and a chamber door 400 is provided corresponding to the food access opening 120, and the chamber door 400 can open and close the food access opening 120. As shown in FIG. 1 , at this time, the chamber door 400 is in an open state, which is convenient for users to take and put food.

The steam generator 200 is used to heat the food placed in the cooking cavity 110, and the heating method is to form high-temperature steam, which is passed into the cooking cavity 110, and the food is cooked with the help of the high-temperature steam. Usually, the cooking chamber 100 and the steam generator 200 can be arranged in the same shell 500. Of course, in other embodiments, the cooking chamber 100 and the steam generator 200 can also be arranged in different shells, so as to form two relatively independent modules and fixedly connected together. Please refer to Figures 1 and 2. In some embodiments, the side where the food access opening 120 is located on the cooking chamber 100 is the front side, and the side opposite to the food access opening 120 is the rear side wall 130. The steam generator 200 is arranged on the rear side wall 130 of the cooking chamber 100. Of course, in other embodiments, the steam generator 200 can also be arranged on other side walls of the cooking chamber 100.

The water tank 300 is connected to the steam generator 200, for example, by a pipeline, an adapter or a direct plug-in. The water tank 300 is used to supply water to the steam generator 200, and the steam generator 200 converts the water obtained from the water tank 300 into steam.

Please refer to FIG. 3-13 , in some embodiments, the water tank 300 has a tank body 310 and a tank cover 320. The tank body 310 has a water injection port 311, and the water injection port 311 is used for a user to inject liquid into the tank body 310. The tank cover 320 is disposed at the water injection port 311, and the tank cover 320 is used to close the water injection port 311, and the tank cover 320 can prevent liquid from leaking or splashing out from the water injection port 311.

The box cover 320 as a whole can be a separate structure from the box body 310, and can be movably connected or detachably connected, so that the user can open the water inlet 311 by moving or removing the box cover 320 when the box cover 320 closes the water inlet 311. Further, please refer to Figures 3-13. In some embodiments, the box cover 320 has a first sealing portion 321 and a second sealing portion 322 that are arranged opposite to each other. Of course, in some embodiments, the box cover 320 can also have other structures besides the first sealing portion 321 and the second sealing portion 322 to achieve corresponding functions.

The box cover 320 has a closed position and an open position. When the box cover 320 is in the closed position, the first cover part 321 and the second cover part 322 jointly close the water injection port 311, that is, the orthographic projections of the first cover part 321 and the second cover part 322 on the horizontal plane at least partially fall within the orthographic projection range of the water injection port 311 on the horizontal plane. At the same time, the first cover part 321 and the second cover part 322 are integrally formed or form a linkage structure, and the two can move together, so that when the box cover 320 is in the open position, the first cover part 321 and the second cover part 322 can open the water injection port 311. Among them, the first cover part 321 and the second cover part 322 open the water injection port 311, including exposing at least a part of the area of the water injection port 311, so that the water injection port 311 can communicate with the outside.

Further, please refer to Figures 3-7. In some embodiments, the box cover 320 is rotatably connected to the box body 310. Among them, the first cover part 321 and the second cover part 322 are arranged relative to each other with the rotation axis c of the box cover 320 as the boundary. In this embodiment, please refer to Figures 3 and 7. When the box cover 320 is in the open position, the first cover part 321 extends into the box body 310 from the water injection port 311, and the second cover part 322 extends outward from the water injection port 311 to open the water injection port 311. In these embodiments, when the user needs to open the water injection port 311, he only needs to press the first cover part 321, which is easy to operate and simple in structure. In some other flip-top box cover 320 structures, a buckle position of a concave or convex structure needs to be reserved on the box body 310 and/or the box cover 320 so that the user can open the box cover 320 more conveniently. These buckle positions are prone to cause the accumulation of water and form scale, which is difficult to clean and easy to contaminate the ingredients during the cooking process. In contrast, in this embodiment, only the first sealing portion 321 needs to be pressed, so no hand-locking positions need to be reserved on the box body 310 and/or the box cover 320, which can reduce cleaning dead corners of the box body 310 and/or the box cover 320 and the accumulation of waste water, making cleaning more convenient.

In some embodiments, the water tank 300 is arranged in the horizontal direction, and the water injection port 311 is arranged on the top wall of the box body 310, so when the box cover 320 is in the closed position, the box cover 320 is also arranged in the horizontal direction. Please refer to Figures 3, 8 and 9. When the box cover 320 is in the closed position, in the horizontal direction perpendicular to the rotation axis c, the size a2 of the second cover part 322 is greater than the size a1 of the first cover part 321. Please refer to Figure 3. This size relationship can ensure that when the user presses the first cover part 321, the water injection port 311 can have a larger opening space, so that it is convenient for the user to add water into the box body 310 through the water injection port 311.

Of course, in some other embodiments, when the box cover 320 is in the closed position, in the horizontal direction perpendicular to the rotation axis c, the size a2 of the second covering portion 322 may also be equal to or smaller than the size a1 of the first covering portion 321 .

Further, please refer to FIG. 6. In some embodiments, when the box cover 320 is in the closed position, the uppermost edge of the peripheral side wall of the box cover 320 is flush with the uppermost edge of the side wall of the water injection port 311. Of course, the flush mentioned here means roughly flush. Due to factors such as manufacturing errors and assembly errors, it is difficult for the uppermost edge of the peripheral side wall of the box cover 320 to be completely flush with the uppermost edge of the side wall of the water injection port 311. Therefore, the upper and lower errors within a certain range are also included in the flush mentioned in this embodiment. When the box cover 320 is flush with the uppermost edge of the water injection port 311, the connection between the box cover 320 and the box body 310 will not form a step structure, so no water accumulation area will be formed, which can further avoid the accumulation of wastewater. Of course, in some other embodiments, the uppermost edge of the peripheral side wall of the box cover 320 can also be lower than the uppermost edge of the side wall of the water injection port 311 to prevent the box cover 320 from protruding from the water injection port 311.

Further, please refer to FIGS. 6-8 , in some embodiments, at least a portion of the end of the first cover portion 321 has a first clamping platform 3211 protruding outward, and the box body 310 has a first stopper 3121 corresponding to the first clamping platform 3211. The first stopper 3121 is arranged on the inner wall of the box body 310, and is located on the movement path of the first clamping platform 3211, so as to form a match with the first clamping platform 3211. Please refer to FIG. 6 , when the first cover portion 321 rotates upward, due to the presence of the first stopper 3121, when the first clamping platform 3211 abuts against the first stopper 3121, the first cover portion 321 can be prevented from continuing to rotate to the outside of the water injection port 311, so as to prevent the user from using too much force when closing the water injection port 311 and causing the first cover portion 321 to tilt out of the water injection port 311.

Further, please refer to Figures 6-8, in some embodiments, the first clamping platform 3211 is a step-shaped structure of one or more sections arranged at the end of the first resisting portion 3121. The first resisting portion 3121 is a step structure arranged around the water injection port 311 on the box body 310. The first clamping platform 3211 and the first resisting portion 3121 are engaged with each other.

Further, please refer to Figures 6-8, in some embodiments, the first clamping platform 3211 surrounds at least three sides of the first sealing portion 321, and the first blocking portion 3121 is arranged corresponding to the first sealing portion 321. In addition to preventing the first sealing portion 321 from rotating outward, the first blocking portion 3121 and the first clamping platform 3211 can also form a sealing structure, thereby further preventing water from leaking from the water injection port 311.

In other embodiments, the first clamping platform 3211 may also be one or more separately arranged protruding structures. The first blocking portion 3121 may also be designed as other structures.

In addition, in order to prevent the first cover portion 321 from rotating outside the water injection port 311, in some embodiments, a limiting structure may be further provided on the second cover portion 322. Referring to FIGS. 9 and 10, in some embodiments, when the box cover 320 is in the closed position, the box cover 320 is at least partially located in the water injection port 311, and at least a portion of the end of the second cover portion 322 has a second clamping platform 3221 protruding outward, and the box body 310 has a second stopper 3122 corresponding to the second clamping platform 3221, so as to prevent the second cover portion 322 from passing through the water injection port 311.

The second card platform 3221 can adopt the same, similar or different structure as the first card platform 3211. Please refer to Figures 9 and 10. In some embodiments, the second card platform 3221 is a step-shaped structure arranged at the end of the second stopper 3122 in one or more sections. The second stopper 3122 is a step structure arranged around the water injection port 311 on the box body 310. The second card platform 3221 and the second stopper 3122 are engaged with each other. In other embodiments, the second card platform 3221 can also be one or more separately arranged protruding structures. The second stopper 3122 can also be designed as other structures.

Further, the box cover 320 and the box body 310 are rotatably connected via a rotating shaft, wherein, please refer to FIGS. 5 and 8 , in some embodiments, the rotating shaft 323 may be disposed between the side wall of the box cover 320 and the side wall of the water injection port 311, thereby ensuring that the rotation axis c between the box cover 320 and the box body 310 is located on the side wall of the box cover 320 and the side wall of the water injection port 311, so that the box cover 320 can be better rotated in the water injection port 311. In other embodiments, the rotating shaft 323 may also be disposed on the outside or inside of the water injection port 311, that is, the position of the rotating shaft 323 is higher or lower than the water injection port 311.

Further, please refer to Figures 5 and 8. In some embodiments, the rotating shaft 323 is protrudingly disposed on the side wall of the box cover 320, for example, it can be an integral structure with the box cover 320, or it can be fixedly or movably connected. In some other embodiments, the rotating shaft 323 can also be protrudingly disposed on the side wall of the water injection port 311, for example, it can be integrally formed with the side wall of the water injection port 311, or it can be fixedly or movably connected.

Further, please refer to FIG6 , in some embodiments, when the box cover 320 is in the closed position, the peripheral side wall of the box cover 320 and the side wall of the water injection port 311 fit each other to achieve a better sealing effect. Of course, the fit mentioned here means roughly fit, because of factors such as manufacturing errors and assembly errors, it is difficult for the peripheral side wall of the box cover 320 and the side wall of the water injection port 311 to fit completely, so this embodiment will also regard the situation with a very small gap as fit, the purpose of which is to avoid leakage of excessive liquid.

Further, please refer to FIG. 6 , in some embodiments, the outer surface of the box cover 320 is flush with the outer surface of the box body 310 or forms a smooth transition, so that the outer surface of the box cover 320 and the outer surface of the box body 310 can form an integral structure, further preventing the accumulation of liquid. In other embodiments, when the outer surface of the box cover 320 and the outer surface of the box body 310 form a smooth transition, the outer surface of the box cover 320 can also be raised from the outer surface of the box body 310.

On the other hand, in some embodiments of the present application, another solution for closing the water injection port 311 is provided, that is, using a magnet to close and open the water injection port 311.

Please refer to Figures 11-13. In some embodiments, the box cover 320 and the box body 310 are two separate parts, one of which is provided with at least one first magnetic member 313, and the other is provided with at least two second magnetic members 324 located at different positions, wherein at least one second magnetic member 324 is used to be magnetically fixed with the first magnetic member 313 when the box cover 320 is in the closed position, and at least one second magnetic member 324 is used to be magnetically fixed with the first magnetic member 313 when the box cover 320 is in the open position. In these embodiments, the first magnetic member 313 is magnetically attracted with the second magnetic members 324 at different positions, thereby fixing the box cover 320 in the open position and the closed position.

Among them, at least one of the first magnetic attraction member 313 and the second magnetic attraction member 324 is a magnetic attraction member, and the other is a magnetic attraction member or a magnetically attracted member. The magnetic attraction member can actively attract other magnetically attracted members, such as magnets or electromagnets. The magnetically attracted member is made of a material that can be attracted by the magnetic attraction member, such as a metal material.

In some embodiments, the box cover 320 can move relative to the box body 310, and the movement method is not limited, as long as the box cover 320 can open and close the water injection port 311. In other embodiments, the user can also open and close the water injection port 311 by removing and installing the box cover 320.

Further, referring to FIGS. 11-13 , in some embodiments, the second magnetic member 324 is disposed on the box cover 320, and the first magnetic member 313 is disposed on the box body 310. In other embodiments, the second magnetic member 324 may also be disposed on the box body 310, and the first magnetic member 313 is disposed on the box cover 320.

Further, please refer to Figures 11-13. In some embodiments, the box body 310 has a guide channel 314, and the box cover 320 is movably arranged in the guide channel 314 to switch between closing and opening the water injection port 311. The guide channel 314 can limit the box cover 320, and the box cover 320 can move in the direction defined by the guide channel 314. The guide channel 314 limits the movement direction of the box cover 320 to a certain extent, which can facilitate the operation of the user, and the user can more easily drive the box cover 320 to move and switch between the open position and the closed position.

In some embodiments, the movement of the box cover 320 relative to the box body 310 can be translation or rotation. Please refer to Figures 11-13. In some embodiments, the water injection port 311 is set through the bottom wall of the guide channel 314, and the box cover 320 translates or rotates on the bottom wall. The translation and rotation movement mode is more convenient for the user to control. Under the guidance and limit of the guide channel 314, the user does not need to actively control the movement direction of the box cover 320, but only needs to control the translation or rotation of the box cover 320.

Further, please refer to Figures 11-13, in some embodiments, the guide channel 314 is recessed on the top wall of the box body 310, and the outer surface of the top wall serves as the bottom wall of the guide channel 314. The guide channel 314 can also be set on the box body 310 in other ways. The upper end of the guide channel 314 is open to facilitate user manipulation.

Further, please refer to Figures 11-13. In some embodiments, the box 310 has a long strip structure, and the guide channel 314 is a groove structure arranged along the length direction of the long strip structure. In addition, in other embodiments, the box 310 can also be a structure of other shapes, not limited to the long strip structure shown in the figure. The shape of the box 310 can be flexibly designed according to the position of the box 310 on the food cooking device 1 and the space occupied.

Further, please refer to Figures 11-13. In some embodiments, the second magnetic component 324 is arranged on the box cover 320, and at least two second magnetic components 324 are arranged front and back along the movement direction of the box cover 320 relative to the box body 310, and the distance between at least two second magnetic components 324 is greater than the size of the water injection port 311 in the movement direction, so as to ensure that when the box cover 320 moves from the open position to the closed position, the first magnetic component 313 can be magnetically fixed to the corresponding second magnetic component 324.

Further, please refer to Figures 11-13. In some embodiments, the box cover 320 is divided into a first cover portion 321 and a second cover portion 322 by a midline d perpendicular to the moving direction thereof. Of course, in other embodiments, other lines may be used as boundaries for division. For example, the size of the first cover portion 321 in the moving direction of the box cover 320 may be greater than, equal to, or less than the size of the second cover portion 322 in the moving direction of the box cover 320.

The first cover part 321 is provided with at least one second magnetic component 324, and the second cover part 322 is provided with at least one second magnetic component 324. The distance between the second magnetic component 324 on the first cover part 321 and the second magnetic component 324 on the second cover part 322 is greater than the size of the water injection port 311 in the movement direction.

Further, the water tank 300 can be fixedly installed in the food cooking device 1 in a non-quickly detachable manner, that is, during use, the water tank 300 is basically not disassembled, and the user directly fills the liquid through the water filling port 311 on the water tank 300. In other embodiments, the water tank 300 is installed in the food cooking device 1 in a quick-detachable manner, and the user can quickly disassemble the water tank 300 to add water or perform other operations.

Please refer to Figures 13-14, in some embodiments, a water tank seat 600 is further included, and the water tank 300 is detachably mounted on the water tank seat 600. The detachable manner may include but is not limited to snap connection, screw connection, detachable bonding, etc.

In some embodiments, the water tank seat 600 can be used as a transfer structure between the water tank 300 and the steam generator 200 in addition to installing the water tank 300. Please refer to Figures 13-15. In some embodiments, the water tank seat 600 has a docking joint 610, and the docking joint 610 is connected to the steam generator 200. The water tank seat 600 can be a fixed structure, that is, when the water tank 300 is removed, the water tank seat 600 remains stationary, so the docking joint 610 and the steam generator 200 always remain connected. After each installation of the water tank 300, the connection between the water tank 300 and the steam generator 200 can be completed as long as the docking of the water tank 300 and the water tank seat 600 is completed.

Please refer to Figures 13-15. In some embodiments, the box body 310 is provided with a water outlet 315, and a water outlet valve 316 for closing the water outlet 315 is provided at the water outlet 315. When the water tank 300 is not connected to the water tank seat 600, the water outlet valve 316 remains in a closed state, and water can be prevented from leaking out of the water outlet 315. When the water tank 300 is installed on the water tank seat 600, the docking joint 610 is connected to the water outlet valve 316. When the water tank 300 is installed on the water tank seat 600, the docking joint 610 can directly or indirectly act on the water outlet valve 316, so that the water outlet valve 316 is switched from a closed state to a conductive state to open the water outlet 315.

Please refer to Figures 13-15. In some embodiments, the water outlet valve 316 includes a valve core 3161 and an elastic pre-tightening member 3162 for shielding the water outlet 315. The elastic pre-tightening member 3162 acts on the valve core 3161 to keep the water outlet valve 316 closing the water outlet 315. The valve core 3161 has a sealing portion 3163. The elastic pre-tightening member 3162 is arranged between the valve core 3161 and the box body 310. The sealing portion 3163 seals the water outlet 315 under the pulling force or thrust of the elastic pre-tightening member 3162. The elastic pre-tightening member 3162 can be a spring, a spring sheet or other elastic member.

The joint 610 has a push-up portion 611 for pushing the valve core 3161 to open the water outlet 315. When the water tank 300 is mounted on the water tank seat 600, the push-up portion 611 can support the valve core 3161 and push it to move to a position to open the water inlet 311. For example, in the embodiment shown in FIG. 13, when the water tank 300 is mounted on the water tank seat 600, the push-up portion 611 pushes the valve core 3161 to move toward the inside of the box body 310. The valve core 3161 may have a channel communicating with the water outlet 315, thereby opening the water outlet 315.

Further, please refer to FIGS. 13-15 , in some embodiments, the box body 310 has a water outlet channel 317, and the water outlet 315 is connected to the water outlet channel 317. The valve core 3161 is inserted into the water outlet channel 317, and when the water tank 300 is installed on the water tank seat 600, the push-up portion 611 of the docking joint 610 is inserted into the water outlet channel 317 to push the valve core 3161 to open the water outlet 315, and the docking joint 610 is sealed and docked with the water outlet channel 317. In order to achieve sealing with the water outlet channel 317, in the embodiments shown in FIGS. 13-15 , a sealing ring 620 or other sealing structure is provided on the peripheral side of the docking joint 610, and the sealing ring 620 is sealed and fitted with the inner wall of the water outlet channel 317.

Further, please refer to Figures 13-14. In some embodiments, the water tank seat 600 has a mounting groove 620, and the mounting groove 620 has a circle of groove walls 621, and the groove walls 621 surround a mounting cavity with an upper end opening. The docking joint 610 is arranged at one end of the mounting groove 620, and the end of the box body 310 having the water outlet 315 is the first end 3181, and the end opposite to the first end 3181 is the second end 3182. When the box body 310 and the docking joint 610 are plugged in and matched, since the mounting groove 620 forms an interference with the second end 3182 of the box body 310, the bottom wall of the second end 3182 has an avoidance area 3183 that retracts toward the inner cavity of the box body 310, so that the box body 310 can be inserted into the mounting groove 620, and the box body 310 and the docking joint 610 on the water tank seat 600 can be plugged in and matched more conveniently. The design of the mounting groove 620 allows the water tank seat 600 to cover the bottom of the water tank 300 after the water tank 300 is installed on the water tank seat 600, thereby positioning the water tank 300. At the same time, the water tank 300 can be fixed by cooperating with the docking head 610 and the box body 310. There is no need to provide an additional fixing structure, thereby simplifying the structure of the water tank 300 and the water tank seat 600.

7 and 13, in some embodiments, the bottom wall of the avoidance area 3183 is higher than the bottom wall of the first end 3181. In the embodiments shown in FIGS. 7 and 13, the avoidance area 3183 forms a height difference, and an inclined transition is formed between the height differences.

In some embodiments, the water inlet 311 is disposed at the second end 3182 of the box body 310, and at least a portion of the avoidance area 3183 is inclined downward from the second end 3182 of the box body 310 toward its first end 3181. In addition to achieving the avoidance function, this angle also helps the water flow toward the water outlet 315 at the first end 3181 to avoid the water from being deposited in the box body 310.

Of course, in other embodiments, the water tank 300 can also be directly inserted into the water tank seat 600 in the direction of the docking joint 610. In this case, the structure of the water tank seat 600 used to match the water tank 300 can be a plane or the movement trajectory of the water tank 300 is a straight line. In this case, the water tank 300 can be fixed only by the plug-in cooperation between the box body 310 and the docking joint 610, and another fixing structure can be provided on the water tank seat 600 to fix the water tank 300.

Further, please refer to Figures 13 and 14. In some embodiments, the circumference of the box body 310 has an inward step structure 3184. After the box body 310 is installed in the installation cavity, the inward step structure 3184 abuts against the groove wall 621 of the installation groove 620, thereby avoiding the formation of an upward gap between the box body 310 and the water tank seat 600.

Further, please refer to Figures 3 and 11. In some embodiments, two opposite side walls of the box body 310 are provided with first handles 319 to facilitate the user to disassemble and assemble the box body 310. The first handle 319 is a groove. Of course, in other embodiments, the first handle 319 can also be a protrusion or other handle structures.

Further, please refer to Figures 8 and 13. In some embodiments, the box cover 320 may also be provided with a second handle portion 325 to facilitate the user to move the box cover 320. In the embodiment shown in Figure 8, the second handle portion 325 is a protrusion. In the embodiment shown in Figure 13, the second handle portion 325 is a groove. Of course, in other embodiments, the second handle portion 325 may also be other handle structures.

Furthermore, the water tank 300 can be arranged at any position outside the cooking chamber 100. Please refer to Figures 1 and 2. In some embodiments, a refrigeration assembly 700 is also included. The refrigeration assembly 700 is used to cool the cooking chamber 110 to keep the food fresh. The water tank 300 is arranged above the refrigeration assembly 700. The water tank 300 and the refrigeration assembly 700 are arranged side by side with the cooking chamber 100. Among them, a second shell 800 can be arranged outside the refrigeration assembly 700. The second shell 800 covers the refrigeration assembly 700. The water tank 300 and the water tank seat 600 can be arranged on the upper part of the second shell 800, and form an integral module with the second shell 800 and the refrigeration assembly 700 to improve the overall aesthetics of the device.

The above embodiments introduce the application of a water tank 300 in a steam-heated food cooking device. In other embodiments, the water tank 300 can also be applied to other types of food cooking devices.
