Description

Technical Field

[0001] The invention relates to a multifunctional oven. Background Art

[0002] The ovens currently on the market are usually equipped with an upper heating device and a lower heating device to meet the various cooking needs of users. However, the design of the existing ovens has some obvious limitations, especially in terms of the functionality and flexibility of the lower heating device.

[0003] The lower heating device of a traditional oven is usually fixed at the bottom of the cabinet, and its height cannot be adjusted, which makes it impossible to flexibly adjust the position of the lower heating device according to actual cooking needs. This fixed design makes it difficult to achieve ideal cooking effects when making certain specific foods. For example, when it is necessary to use the upper and lower heating devices to clamp food (such as grilled steaks or sandwiches) for cooking, the fixed height of the lower heating device cannot meet the requirements of ingredients of different thicknesses, limiting the user experience.

[0004] In addition, the lower heating device of the prior art is usually fixed inside the cabinet and cannot be slid out of the cabinet, which brings operational inconvenience in certain usage scenarios. For example, when a user wants to place a pot directly on the lower heating device to cook noodles or other cooking operations, the user needs to operate in a narrow cabinet due to the fixed position of the lower heating device, which is not only inconvenient but also may bring safety hazards. Summary of the invention

[0005] The object of the present invention is to provide a multifunctional oven whose height can be adjusted and whose lower heating device can slide out of the cabinet along with the drawer, thereby improving the versatility and convenience of use of the oven.

[0006] The object of the present invention is achieved in that: A multifunctional oven comprises a cabinet body, a cabinet door, a lifting device and a lower heating device, wherein the cabinet door is hinged on the cabinet body. At least one upper heating device is provided at the top of the inner cavity of the cabinet; The inner cavity of the cabinet is provided with at least one drawer, and the drawer slides into or out of the inner cavity of the cabinet; The lifting device is detachably arranged on the drawer, the lower heating device is connected to the lifting device, and the lifting device drives the lower heating device to rise and fall.

[0007] By setting a lifting device on the drawer and connecting it to the lower heating device, the height adjustment function of the lower heating device is realized. Users can adjust the position of the lower heating device at will according to cooking needs, so that it can be used in conjunction with the upper heating device to meet the clamping cooking needs of ingredients of different thicknesses (such as grilled steaks or sandwiches), greatly improving the adaptability and ease of use of the oven.

[0008] The lower heating device is fixed on the drawer, and the drawer can slide into or out of the cabinet cavity. When the drawer slides out of the cabinet, the user can easily place the pot directly on the lower heating device, which is convenient for various cooking operations such as cooking noodles, avoiding the inconvenience of operating in the cabinet, and improving the safety and comfort of use.

[0009] This design not only realizes the traditional baking function by realizing the coordinated work of the upper and lower heating devices, but also has the functions of clamping cooking (such as frying and baking) and direct heating of pots. The height-adjustable design of the lower heating device expands the use of the oven, which can meet the cooking needs of users in various scenarios, making the oven a more practical and multifunctional kitchen equipment.

[0010] Through the design of the detachable lifting device, the lower heating device can be easily disassembled and installed, which is convenient for users to clean and maintain the internal structure of the oven, thereby extending the service life of the oven and improving the overall user experience.

[0011] The purpose of the present invention can also be solved by the following technical measures: Furthermore, it also includes a vertical partition plate, which is detachably arranged in the inner cavity of the cabinet, and the vertical partition plate divides the inner cavity of the cabinet into a left cavity and a right cavity; The upper heating device is arranged at the top of the left cavity, and the drawer is arranged at the bottom of the left cavity; The upper heating device is arranged on the top of the right cavity, and the drawer is arranged on the bottom of the right cavity.

[0012] Users can choose whether to install a vertical partition board according to actual cooking needs. When cooking multiple ingredients at the same time, the partition board can be used to separate the cabinet cavity into independent left and right cavities, so that different ingredients can be cooked separately, effectively avoiding the smell of different ingredients and improving cooking efficiency.

[0013] The left and right cavities are equipped with upper heating devices and drawers, and the lower heating devices can be adjusted in height with the lifting device. Users can set different cooking modes in different cavities, such as baking food in the left cavity and cooking steak or sandwiches in the right cavity, to meet the cooking needs of different ingredients.

[0014] The vertical partitions are designed to be detachable, so users can easily install or remove them. When a larger cooking space is needed, the partitions can be quickly removed to restore the overall space of the cabinet, making it convenient to bake large-sized ingredients. This design enhances the space utilization and flexibility of the oven.

[0015] The left and right cavities can be cooked using independent heating devices. When users only need to cook a small amount of ingredients, they can choose to use only a single cavity for cooking, thereby reducing energy consumption and achieving higher energy efficiency, which meets the requirements of energy saving and environmental protection of modern kitchen equipment.

[0016] Through the design of vertical partitions, the oven not only supports traditional baking functions, but also supports zoned cooking mode. Different cavities can perform different cooking operations simultaneously, which significantly improves the functionality and applicability of the oven, making it a multi-functional cooking device in the user's kitchen.

[0017] The divider can be easily removed to facilitate thorough cleaning of the oven cavity, helping to maintain the hygiene of the oven and extend the life of the equipment.

[0018] Furthermore, it also includes a transverse partition plate, which is detachably arranged in the left cavity, and the transverse partition plate divides the left cavity into an upper left cavity and a lower left cavity. The upper heating device is arranged at the top of the upper left cavity, and the drawer is arranged at the bottom of the lower left cavity.

[0019] The transverse partition is detachably arranged in the right cavity, and the transverse partition divides the right cavity into an upper right cavity and a lower right cavity. The upper heating device is arranged at the top of the upper right cavity, and the drawer is arranged at the bottom of the lower right cavity.

[0020] By setting the horizontal partition plate, users can separate the left and right cavities up and down according to actual needs, forming four independent cooking spaces: the upper left cavity, the lower left cavity, the upper right cavity and the lower right cavity. This design can meet the needs of users to cook multiple ingredients at the same time, and significantly improve the space utilization of the oven.

[0021] Users can choose whether to install a horizontal partition. When cooking smaller ingredients, the partition can be installed to process more ingredients at the same time; when a larger cooking space is needed, the partition can be removed to accommodate larger ingredients or cooking utensils. This design enhances the flexibility of the device.

[0022] Users can set different cooking temperatures or modes in different cavities, such as baking in the upper left cavity, frying in the lower left cavity, and performing other cooking operations in the upper right cavity and lower right cavity at the same time, realizing true multi-tasking cooking.

[0023] Users can selectively use part of the cavity for cooking operations. For example, when only a small amount of heating space is needed, the heating device of the unused cavity can be turned off to reduce unnecessary energy consumption, thereby achieving more efficient energy utilization and complying with modern environmental protection concepts.

[0024] The upper and lower chambers provide users with more cooking options. For example, users can bake in the upper chamber and hold cooking ingredients or heat pots in the lower chamber. By combining the functions of different chambers, users can complete more complex multi-step cooking tasks, significantly improving the practicality and versatility of the oven.

[0025] The transverse partition is detachable, allowing users to easily install or remove the partition. After removal, the inner cavity is easier to clean, avoiding the accumulation of oil stains or residues, making maintenance more convenient, helping to maintain the hygiene of the equipment and extend its service life.

[0026] Furthermore, it also includes a circuit board, and the upper heating device and the lower heating device are respectively connected to the circuit board, and the circuit board controls the power on and off of the upper heating device and the lower heating device.

[0027] Through the control of the circuit board, users can choose to turn on or off the upper and lower heating devices according to cooking needs, realizing precise management of the heating process. For example, in certain cooking modes, users can turn on only the upper heating device for single-sided baking, or turn on the upper and lower heating devices to work at the same time to meet the requirements of different ingredients and cooking methods.

[0028] The circuit board can be equipped with human-computer interaction interfaces such as buttons, knobs or touch screens, making user operation more convenient and intuitive. Through the functional control interface, users can quickly switch heating modes, adjust working status or set heating time, greatly improving the user experience of the device.

[0029] The introduction of circuit boards makes it possible to integrate intelligent functions into equipment. For example, temperature sensors and current monitoring modules can be added to enable the circuit board to intelligently adjust the power or operating time of the heating device according to the ingredients or cooking mode, prevent overheating or undercooking, and realize intelligent cooking.

[0030] The circuit board can be equipped with protection circuits and fault detection functions, such as overload protection, short circuit protection, and overheating protection. When the device is abnormal, the circuit board can cut off the power supply in time to ensure the safety of the device and the user. At the same time, the circuit board can remind the user of the operating status of the device through status indicators or prompt sounds.

[0031] The circuit board precisely controls the on and off of the heating device, avoiding long-term continuous heating or unnecessary heating, significantly reducing energy consumption. This energy-saving design not only meets the needs of modern families for low-energy devices, but also reduces the impact on the environment.

[0032] The control function of the circuit board supports fast switching of multiple cooking modes. For example, users can select separate upper and lower heating, zone heating or full cavity heating through preset modes to flexibly adapt to different cooking needs. This multi-mode compatibility makes the device more versatile and further enhances the practicality of the oven.

[0033] To sum up, by setting a circuit board to control the power on and off of the upper heating device and the lower heating device, the present invention not only improves the operating convenience and safety of the oven, but also significantly enhances the intelligence, energy saving and functional diversity of the equipment, fully meeting the needs of modern users for high-performance kitchen equipment.

[0034] Furthermore, it also includes a high temperature resistant power supply line, which is arranged in the cabinet, one end of the high temperature resistant power supply line is connected to the circuit board, and the other end of the high temperature resistant power supply line is connected to the lower heating device. When the lower heating device is located in the cabinet or outside the cabinet, the circuit board controls the power on and off of the lower heating device through the high temperature resistant power supply line.

[0035] High temperature resistant power supply lines can work stably in high temperature environments, effectively avoiding line aging, short circuit or damage caused by excessive temperature, ensuring power supply safety and long-term reliable operation of equipment.

[0036] The setting of high-temperature resistant power supply lines supports the lower heating device to be located inside the cabinet or slid out of the cabinet for operation without additional adjustment of circuit connections. Users can freely adjust the position of the lower heating device according to cooking needs, such as for clamping cooking or heating pots separately, which significantly improves the flexibility and practicality of the oven.

[0037] The high temperature resistant power supply line can provide a reliable electrical connection to ensure that the lower heating device can obtain stable power support at different positions, thereby ensuring that the heating effect of the heating device is not affected by position changes, thereby improving the performance stability of the oven.

[0038] The high temperature resistant power supply line effectively reduces the wire loss and replacement frequency caused by high temperature, reduces the maintenance cost of the equipment, and at the same time extends the service life of the overall oven, improving the product's economy and user experience.

[0039] When the lower heating device slides out of the cabinet, the design of the high temperature resistant power supply line ensures that the circuit board can still accurately control the power on and off of the lower heating device. For example, users can use the lower heating device outside the cabinet to cook noodles or fry, which expands the application scenarios of the oven and makes it have both baking and cooking functions.

[0040] High temperature resistant power cables have strong wear resistance and heat resistance, which can effectively prevent damage caused by cable dragging or sliding. At the same time, high temperature resistant materials reduce the fire hazard of wires in high temperature environments, further improving the safety performance of the equipment.

[0041] The design of the high temperature resistant power supply line enables the user to achieve free sliding and position adjustment of the lower heating device without complicated operations, while maintaining the normal power supply and functional use of the lower heating device, greatly simplifying the operation process of the equipment.

[0042] Furthermore, it also includes a high temperature resistant plug, a high temperature resistant socket and a high temperature resistant power supply line. The high temperature resistant socket is arranged in the inner cavity of the cabinet, and the high temperature resistant socket is electrically connected to the circuit board. One end of the high temperature resistant power supply line is connected to the lower heating device, and the other end of the high temperature resistant power supply line is connected to the high temperature resistant plug. The high temperature resistant plug and the high temperature resistant socket are plugged together, and the circuit board controls the power on and off of the lower heating device through the high temperature resistant socket, the high temperature resistant plug and the high temperature resistant power supply line.

[0043] The plug-in design of the high-temperature resistant plug and the high-temperature resistant socket allows the user to easily disconnect the electrical connection of the lower heating device and quickly disassemble the lower heating device for separate cleaning, avoiding the cleaning inconvenience caused by the fixed design, greatly improving the cleaning convenience and maintenance efficiency of the equipment.

[0044] The modular design of high-temperature resistant plugs and sockets can be quickly disassembled and assembled without complicated tools or technical operations. Ordinary users can also operate it easily, which significantly improves the user experience of the equipment.

[0045] Both the high temperature resistant plug and the high temperature resistant socket are made of high temperature resistant materials, which can maintain good electrical connection in high temperature environment, avoiding poor contact problems caused by high temperature or frequent plugging and unplugging, thereby ensuring stable power supply and normal operation of the heating device.

[0046] The design of high temperature resistant plug and socket reduces the wear of power cord during frequent use and facilitates the individual replacement of damaged parts, avoiding the maintenance difficulties caused by the overall non-detachable design, thereby extending the service life of the equipment and reducing the user's maintenance costs.

[0047] High temperature resistant plugs and sockets have good heat resistance and durability, and can prevent safety hazards such as short circuits, overheating or fire in high temperature environments. At the same time, its plug-in design avoids the damage of traditional fixed wires due to excessive pulling during the sliding process, further improving the safety of the equipment.

[0048] The plug-in design allows the lower heating device to easily slide out of the cabinet for independent use, such as for cooking noodles or frying. It also supports quick reinstallation back into the cabinet to continue clamping or heating operations, meeting cooking needs in different scenarios and enhancing the applicability of the equipment.

[0049] The modular design of the high temperature plug and socket is not only convenient for users to operate, but also makes the product more efficient in production and maintenance. Each component can be manufactured, tested and replaced independently, reducing the difficulty of production and the cost of subsequent maintenance.

[0050] Furthermore, the cabinet is provided with at least one upper heating cavity at the top of the inner cavity of the cabinet, and the upper heating device is an upper heating tube, which is arranged in the corresponding upper heating cavity.

[0051] The upper heating tube is arranged in the upper heating cavity, and the heating element is covered by the heating cavity, which effectively improves the heat gathering efficiency, reduces heat loss, and improves the overall baking efficiency.

[0052] Furthermore, it also includes an upper baking tray, which is detachably arranged in the corresponding upper heating cavity and located below the upper heating tube.

[0053] The upper baking tray is detachable, which allows users to replace different types of baking trays (such as flat trays, corrugated trays, etc.) according to actual needs to meet diverse cooking needs. In addition, the detachable design makes it easy to take out and clean, ensuring the cleanliness and long-term use of the equipment.

[0054] Furthermore, the lower heating device includes a shell and a lower heating tube, the shell is connected to the lifting device, the shell is provided with a lower heating cavity, and the lower heating tube is arranged in the lower heating cavity.

[0055] The lower heating tube is arranged in the lower heating cavity, and the heating element is covered by the heating cavity, which effectively improves the heat gathering efficiency, reduces heat loss, and improves the overall baking efficiency.

[0056] The lifting design of the lower heating device further enhances the flexibility of heating. Users can adjust the height of the lower heating device by lifting it, so that the lower heating tube is close to the food, enhancing the heating effect, which is especially suitable for sandwiches, steaks and other cooking scenarios.

[0057] Furthermore, it also includes a lower baking tray, which is detachably arranged in the lower heating cavity and located above the lower heating tube.

[0058] The lower baking tray is detachable, which allows users to replace different types of baking trays (such as flat trays, corrugated trays, etc.) according to actual needs to meet diverse cooking needs. In addition, the detachable design makes it easy to take out and clean, ensuring the cleanliness and long-term use of the equipment.

[0059] The upper baking tray is located below the upper heating tube, and the lower baking tray is located above the lower heating tube, and can be used to bake different types of ingredients. By combining the upper and lower heating tubes and baking trays, multi-functional cooking modes such as multi-layer baking, clamping heating, and independent heating can be achieved, significantly expanding the use of the oven.

[0060] With the upper and lower heating devices working independently or jointly, users can choose single baking, upper and lower sandwich heating or multi-layer baking mode according to their needs. For example, when baking cakes, the upper and lower parts can be heated at the same time, and when making sandwiches, the upper and lower parts can be sandwiched and heated, which greatly enriches the cooking scenes.

[0061] Furthermore, it also includes a transmission device, a handle and a lifting controller, wherein the handle is arranged on the outer wall of the cabinet; The transmission device is arranged on the cabinet, the input end of the transmission device is connected to the handle, and the output end of the transmission device is located in the inner cavity of the cabinet; The lifting controller is arranged on the drawer, and the lifting device is connected to the lifting controller; When the drawer slides into the inner cavity of the cabinet, the output end of the transmission device is connected to the lifting controller, the handle moves, the handle drives the lifting controller to move through the transmission device, and the lifting controller drives the lifting device to move, thereby adjusting the height of the lower heating device.

[0062] Through the operation of the handle, the transmission device transmits the external mechanical force to the lifting controller, thereby driving the lifting device to move. This design allows users to accurately control the height of the lower heating device and adjust it according to the cooking needs of different ingredients to ensure the best heating effect, which is particularly suitable for clamping heating scenarios.

[0063] The handle is set on the outer wall of the cabinet, which is convenient for users to operate. The height of the lower heating device can be adjusted without opening the cabinet door. The operation is intuitive and labor-saving, which greatly improves the user experience of the equipment.

[0064] The input end of the transmission device is connected to the handle, and the output end is connected to the lifting controller. When the drawer slides into the cabinet cavity, the transmission device and the lifting controller are reliably connected. This design ensures that the lifting function is only enabled after the drawer is returned to its original position, which improves the stability and safety of the system.

[0065] After the drawer is returned to its original position, the user can dynamically adjust the height of the lower heating device at any time through the handle without interrupting the cooking process to meet the needs of different cooking stages, such as holding a sandwich or adjusting the lower heating device close to the bottom of the pot for centralized heating.

[0066] The introduction of the height adjustment function further expands the scope of application of the oven. Users can not only achieve clamping heating, but also flexibly adjust it according to the height of the pot or the thickness of the ingredients, adapting to more diverse cooking scenarios and enhancing the practical value of the equipment.

[0067] The docking design of the transmission device and the lifting controller ensures that the movement of the handle will not affect the internal structure of the equipment. When the drawer is not in the return position, the output end of the transmission device is disconnected from the lifting controller, avoiding equipment damage or safety hazards that may be caused by misoperation.

[0068] By combining the handle with the transmission device, the traditional electric lifting and adjustment design is simplified, the manufacturing cost is reduced, and the accuracy and stability of the adjustment function are ensured. This innovative design adds unique functions to the oven products and improves the market competitiveness.

[0069] The handle is ergonomically designed and users only need to rotate or pull to complete the adjustment. The operation process is natural and smooth, suitable for all types of users, especially the elderly and children, expanding the applicable population of the device.

[0070] Further, the lifting controller includes a front screw rod, a front nut, a rear screw rod, a rear nut and a control rod, the front screw rod and the rear screw rod are opposite to each other, the front nut is sleeved on the front screw rod, and the rear nut is sleeved on the rear screw rod; The end of the front screw rod facing the rear screw rod is provided with a front gear, and the end of the rear screw rod facing the front screw rod is provided with a rear gear; The front end of the control rod is provided with a gear plate, the front gear and the rear gear are respectively meshed with the teeth of the gear plate, and the rear end of the control rod is provided with a first transmission gear for connecting to the output end of the transmission device; The front nut and the rear nut are respectively connected to the lifting device in a detachable manner; The control rod drives the gear plate to rotate, and the gear plate drives the front screw and the rear screw to rotate respectively, so that the front nut and the rear nut slide, and the sliding of the front nut and the rear nut drives the lifting device to unfold or fold, thereby adjusting the height of the lower heating device.

[0071] The height of the lifting device can be precisely controlled through the spiral structure of the front screw, front nut, rear screw and rear nut. When the control rod rotates, the gear plate drives the front and rear screws to rotate, and the front nut and rear nut slide, thereby finely adjusting the position of the lower heating device to ensure precise lifting and lowering to meet different cooking needs.

[0072] The meshing design of the gear plate on the control lever and the front and rear gears ensures smooth force transmission, allowing the lifting device to operate smoothly without sticking, avoiding common mechanical wear and failure problems, and improving the durability and stability of the equipment.

[0073] The present invention adopts a manual mechanical adjustment method, through the combination of front and rear screws, gear plates and control rods, which not only improves the accuracy, but also reduces the potential problems caused by the electric system, improves the stability and service life of the product, and thus enhances the market competitiveness of the oven product.

[0074] The adjustable lifting function enables the lower heating device to be flexibly adjusted according to different cooking needs, supporting more types of cooking, such as frying, grilling, clamping heating, etc., providing users with more cooking options and enhancing the versatility of the oven.

[0075] Furthermore, the transmission device includes a reducer and a second transmission gear, the reducer is arranged on the cabinet, the input end of the reducer is connected to the handle, the output end of the reducer extends into the inner cavity of the cabinet, and the second transmission gear is arranged on the output end of the reducer for connecting to the first transmission gear.

[0076] The setting of the reducer effectively reduces the rotation speed of the handle input, making the action of the lifting controller smoother. Through the reduction device, the speed during the transmission process is controlled, avoiding the vibration or instability that may be caused by rapid rotation, and ensuring the smoothness and stability of the lifting process.

[0077] The reducer slows down the rotation speed of the handle, making it easier for the user to operate. Due to the existence of the reducer, the user does not need to use too much force to adjust the height of the lower heating device, which reduces the labor intensity during operation and improves the comfort and convenience of use.

[0078] The introduction of the reducer makes the lifting process more refined and ensures more precise fine-tuning of the lifting device. This is essential for cooking scenarios that require precise height control and can meet the different heating requirements of various ingredients, such as clamping heating or pot height adjustment.

[0079] The use of the reducer allows the lower heating device to achieve a larger lifting range even with a smaller rotation of the handle, which greatly reduces the difficulty of user operation, making it suitable for more user groups with different strengths and needs, and increasing the user-friendliness of the product.

[0080] Because the reducer can smoothly adjust the lifting and lowering speed, the oven can adapt to different cooking scenarios more flexibly, whether it is rapid heating or clamping heating that requires fine control, it can easily handle it.

[0081] Further, the lifting device is a lifting bracket, and the lifting bracket includes a first bracket and a second bracket, the first bracket and the second bracket are connected, the upper end of the first bracket is connected to the rear end of the lower heating device, and the lower end of the first bracket is detachably connected to the front nut; The upper end of the second bracket is connected to the front end of the lower heating device, and the lower end of the second bracket is detachably connected to the rear nut; The lifting device and the lower heating device are connected to form a first module, and the first module and the drawer are detachably connected to form a second module; When the front nut and the rear nut are close to each other, the lifting bracket is unfolded to drive the lower heating device to rise; when the front nut and the rear nut are away from each other, the lifting bracket is folded to drive the lower heating device to fall.

[0082] The user can disassemble the first module (lifting device and lower heating device combination) for cleaning as needed, and can disassemble the second module (lifting device, lower heating device and drawer combination) as a whole for cleaning.

[0083] This design makes it easy for users to clean all heating parts, avoids hygiene problems caused by dirt accumulation due to long-term use, and improves the user experience and hygiene of the equipment.

[0084] With the detachable lifting bracket structure, users can choose to disassemble the second module (lifting device, lower heating device and drawer combination) for cleaning, or disassemble the first module (lifting device and lower heating device combination) alone without disassembling the drawer. This provides users with greater flexibility, facilitating cleaning and maintenance according to actual needs, saving time and energy.

[0085] Since the lifting bracket and the lower heating device can be disassembled easily and conveniently, users can perform maintenance without additional tools or complicated steps, which improves the operability of the product. Especially in environments with limited space such as kitchens, the easy disassembly design can greatly improve the practicality and maintenance convenience of the product.

[0086] Users can disassemble the entire first module (lifting device and lower heating device combination) and clean it separately, avoiding the problem of difficult cleaning due to fixed parts in traditional ovens. Even if multiple parts need to be disassembled during the cleaning process, the simple disassembly method reduces the difficulty of cleaning, ensures that the equipment remains in a good hygienic state, and reduces food residue.

[0087] Due to the disassembly design between the lifting bracket and the front and rear nuts, users can easily clean the first module (lifting device and lower heating device combination) without removing the drawer and other parts. This saves space and avoids the inconvenience caused by large-scale disassembly, making the operation more concise and efficient.

[0088] Since the lifting bracket can be unfolded to drive the lower heating device up when the front and rear nuts are close together, and can be folded to drive the lower heating device down when they are far away, this structure not only improves the stability of the lifting bracket, but also makes the lifting process more stable and smooth. The stability during the disassembly process is also guaranteed, avoiding the instability caused by excessive disassembly.

[0089] The detachable design allows users to promptly clean any dust or oil that may affect the performance of the device, avoiding damage to the device or reduced heating efficiency due to the accumulation of such dirt, thereby extending the service life of the product.

[0090] After cleaning, the first module (lifting device and lower heating device combination) can maintain the best working condition, avoiding overheating, malfunction or damage caused by dirt accumulation. The simplicity and safety of the cleaning process improves the long-term stability of the equipment and reduces potential safety hazards caused by improper cleaning.

[0091] The easy disassembly and cleaning design greatly improves the user experience, reduces the difficulty of maintenance, and increases user satisfaction with the equipment. After cleaning, the reliability and performance of the equipment can be maintained, enhancing the overall competitiveness of the product.

[0092] The beneficial effects of the present invention are as follows: The present invention realizes the height adjustment function of the lower heating device by arranging a lifting device on the drawer and connecting it with the lower heating device. The user can adjust the position of the lower heating device at will according to cooking needs, so that it can be used in conjunction with the upper heating device to meet the clamping cooking needs of ingredients of different thicknesses (such as grilled steaks or sandwiches), greatly improving the adaptability and ease of use of the oven.

[0093] In the present invention, the lower heating device is fixed on the drawer, and the drawer can slide into or out of the cabinet cavity. When the drawer slides out of the cabinet, the user can easily place the pot directly on the lower heating device, which is convenient for performing various cooking operations such as cooking noodles, avoiding the inconvenience of operating in the cabinet, and improving the safety and comfort of use.

[0094] According to the present invention, the user can disassemble the first module (the lifting device and the lower heating device combination) for cleaning as needed, and can disassemble the second module (the lifting device, the lower heating device and the drawer combination) as a whole for cleaning. This design makes it convenient for the user to clean all parts involved in heating, avoids the hygiene problems caused by the accumulation of dirt due to long-term use, and improves the use experience and hygiene of the equipment.

[0095] The present invention allows users to choose whether to install a vertical partition plate according to actual cooking needs. When multiple ingredients need to be cooked at the same time, the partition plate can be used to separate the cabinet cavity into an independent left cavity and a right cavity, thereby achieving the purpose of cooking different ingredients separately, effectively avoiding the smell of the ingredients, and improving cooking efficiency.

[0096] The present invention, through the provision of a transverse partition plate, the user can separate the left cavity and the right cavity up and down according to actual needs, forming four independent cooking spaces, namely the upper left cavity, the lower left cavity, the upper right cavity and the lower right cavity. This design can meet the user's needs for cooking multiple ingredients at the same time, and significantly improve the space utilization of the oven.

[0097] The plug-in design of the high temperature resistant plug and the high temperature resistant socket of the present invention enables the user to easily disconnect the electrical connection of the lower heating device and quickly disassemble the lower heating device for separate cleaning, thereby avoiding the cleaning inconvenience caused by the fixed design, and greatly improving the cleaning convenience and maintenance efficiency of the equipment.
