A microwave oven is a kitchen appliance that uses electromagnetic waves in the microwave frequency band to heat food. If you wake up late in the morning, you can put bread slices into the heating cavity.

[0003] In some existing microwave ovens, the microwave heating cavity generates electromagnetic waves in the microwave frequency band through an internal magnetron. When microwaves penetrate food, they cause polar molecules such as water and fat molecules in the food to vibrate at high speed. The friction and collision between molecules generate heat, thereby quickly heating, defrosting, and simple cooking of food.

Industrial microwave ovens with conveyor belt tunnels have many drawbacks, such as uneven heating of materials, dispersion of microwave energy, difficulty in controlling the heating time of materials, and uneven feeding and placement, which leads to uneven heating. To address these issues, a multi-purpose multi-cavity microwave oven is proposed. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] A multi-purpose, multi-cavity microwave oven, with reference to Figures 1 to 3The bottom frame 1 serves as the core load-bearing foundation of the entire microwave oven, featuring excellent load-bearing capacity and structural stability. It can support the weight of all functional components at the top, while its flat top surface provides a reference for the precise fixing of each component, preventing misalignment due to frame deformation and ensuring the overall operational accuracy of the equipment. It also serves as heat insulation and protection, preventing internal heat leakage and burns to users. The top of the bottom frame 1 is fixedly connected to multiple material trays 2, a total of four, for placing food to be heated. These trays are high-temperature resistant, microwave-penetrating, non-toxic, harmless, and food-safe. The bottom is equipped with a cylinder for easy up-and-down movement, and can adjust its position according to the height of the food, ensuring that the food is in the optimal heating area within the top structure. In conjunction with the top structure, it forms a relatively closed heating cavity, preventing microwave leakage and heat loss, and ensuring heating efficiency and safety.

[0031] Specifically, the bottom frame 1 of this multi-purpose multi-cavity microwave oven serves as the core load-bearing foundation. It supports all functional components on top with its excellent load-bearing capacity and stability, and provides a benchmark for the precise fixing of components with a flat top surface, preventing the frame from deforming and causing component misalignment, thus ensuring the accuracy of equipment operation. At the same time, it also has a heat insulation and protection function to prevent internal heat leakage and burns to users. The four material trays 2 on the top can stably place the food to be heated. They are not only high-temperature resistant, microwave-penetrable, and non-toxic and harmless food contact safe, but also can be adjusted up and down by the bottom cylinder to deliver the food to the optimal heating area in the top structure according to the height of the food. They also work with the top structure to form a relatively closed heating cavity, effectively preventing microwave leakage and heat loss, balancing heating efficiency and safety.

[0032] The top of the bottom frame 1 is fixedly connected to a heating cavity moving frame 3, which has reserved slide rails and mounting slots inside to provide movement guidance and support for the internal connecting structure. Its inner wall is treated to prevent microwave reflection and reduce microwave energy loss. The top of the bottom frame 1 is fixedly connected to two slide rails 14, which are wear-resistant and high-temperature resistant, and the surface is polished to reduce the coefficient of friction, making it easy for the top structure to slide on them. The two slide rails 14 are parallel. The heating cavity moving frame 3 is fixedly connected to two vertical lifting devices 5 inside, which drive the bottom connecting structure to achieve vertical lifting movement. The two vertical lifting devices 5 are parallel. The parallel arrangement ensures uniform force on the heating chamber and avoids tilting or offset during the lifting process. Each lifting device 5 is fixedly connected to a microwave light wave heating moving chamber 6 at its bottom. The connection between the two is equipped with a buffer pad to reduce the impact during the lifting process. When the lifting device 5 receives the electronic control signal, the piston rod extends and retracts, which can drive the microwave light wave heating moving chamber 6 to slide up and down along the slide rail inside the heating chamber moving frame 3, so as to achieve precise docking and separation between the heating chamber and the material tray 2. The microwave light wave heating moving chamber 6 is a closed cavity structure, which can form an independent heating space and prevent heat and microwave crosstalk between different cavities.

[0033] Specifically, the heating cavity moving frame 3 at the top of the bottom frame 1 provides guidance and support for the internal structure through the reserved slide rails and installation slots. The anti-microwave reflection treatment on the inner wall can also reduce energy loss. The two parallel slide rails 14 are wear-resistant, high-temperature resistant, and have low surface friction, which facilitates the smooth sliding of the top structure. The two parallel up-and-down lifting devices 5 inside the heating cavity moving frame 3 can drive the bottom structure to rise and fall smoothly, avoiding tilting and deviation. The buffer pad at the connection reduces impact. The microwave light wave heating moving cavity 6 connected at the bottom can slide along the slide rail to achieve precise docking and separation with the material tray 2. The closed structure forms an independent heating space, effectively preventing heat and microwave crosstalk between cavities.

[0034] A cylinder 4 is fixedly connected to the top of the bottom frame 1. The drive end of the cylinder 4 is fixedly connected to the bottom of the heating chamber moving frame 3. The two microwave light wave heating moving cavities 6 are externally slidably connected to the inside of the heating chamber moving frame 3 and move back and forth when working. The lateral sliding of the cylinder 4 realizes the alternating feeding of the two material trays 2, which improves the production efficiency. A sealing ring 7 is fixedly connected to the bottom of the microwave light wave heating moving cavity 6. It has the characteristics of high temperature resistance and good elasticity. It is fixed in the sealing groove of the bottom and edge of the microwave light wave heating moving cavity 6. When the microwave light wave heating moving cavity 6 descends and docks with the material tray 2, it fills the gap between the two, realizes the sealing of the heating cavity, prevents microwave leakage from the gap, ensures the safety of use, and also reduces the heat loss in the cavity, improves the heating efficiency, and forms a sealed fit with the microwave light wave heating moving cavity 6 and the material tray 2 to ensure the sealing effect.

[0035] Specifically, the cylinder 4 at the top of the bottom frame 1 is connected to the bottom of the heating chamber moving frame 3 at the top center of the frame 1. The cylinder 4 can achieve the alternating feeding of the two material trays 2 by sliding laterally, effectively reducing material waiting time and significantly improving production efficiency. The two microwave light wave heating moving cavities 6 move back and forth outside and inside the heating chamber moving frame 3 during operation to ensure motion stability. The sealing ring 7 at the bottom of the microwave light wave heating moving cavity 6 has the characteristics of high temperature resistance and good elasticity. It is fixed in the bottom and edge sealing grooves and can fill the gap when docking with the material tray 2 to achieve the sealing of the heating cavity. This not only prevents microwave leakage and ensures safe use, but also reduces heat loss in the cavity to improve heating efficiency. It also forms a good sealing fit with the microwave light wave heating moving cavity 6 and the material tray 2 to ensure reliable sealing effect.

[0036] A double-layer superimposed heat dissipation assembly 8 is fixedly connected to the top of the microwave light wave heating moving cavity 6. This structure adopts a double-layer heat sink structure with a ventilation gap reserved between the two layers of heat sinks, which can increase the heat dissipation area and dissipate heat for the microwave magnetron 9 and the heating components inside the double-layer superimposed heat dissipation assembly 8. The heat generated by the components is absorbed and conducted to the surface through the heat sink, and the internal structure accelerates the heat dissipation to avoid damage to the components due to high temperature overload. The microwave magnetron 9 is fixedly connected inside the double-layer superimposed heat dissipation assembly 8. The microwave magnetron 9 is fixed to the heat sink inside the double-layer superimposed heat dissipation assembly 8 by an insulating bracket. The microwave magnetron 9 is in close contact with the heat sink to improve the heat conduction efficiency. The microwave magnetron 9 is the core component for microwave generation. Through the high-frequency current excitation provided by the internal structure of the double-layer superimposed heat dissipation assembly 8, a high-frequency oscillation is formed inside the microwave magnetron 9 to generate microwave energy. The microwave magnetron 9 transmits the energy directly to the microwave light wave heating moving cavity 6 through the waveguide at the bottom, which acts on the material molecules to make them vibrate at high frequency and generate heat, thus achieving rapid heating.

[0037] Specifically, the double-layered heat dissipation assembly 8 at the top of the microwave light wave heating moving cavity 6 uses double-layer heat sinks and has reserved ventilation gaps, which can greatly increase the heat dissipation area, efficiently absorb and conduct heat from internal heating components such as the microwave magnetron 9, and accelerate heat dissipation with the internal structure, which can prevent components from being damaged due to high temperature overload. The microwave magnetron 9 inside the assembly is installed and fixed on the microwave light wave heating moving cavity 6, and the tight fit improves the heat conduction efficiency. As the core component for microwave generation, it generates microwave energy by high-frequency oscillation through high-frequency current excitation, and then directly transmits it to the heating cavity through the bottom waveguide, causing the material molecules to vibrate at high frequency and generate heat, achieving rapid heating while taking into account both heat dissipation reliability and heating efficiency.

[0038] The double-layer stacked heat dissipation assembly 8 has an internally fixedly connected cavity light wave tube 10, which is an auxiliary heating component. When working, it is powered by a power supply. The tungsten filament in the tube heats up and generates infrared rays. The infrared rays penetrate the outer tube and directly irradiate the surface of the material in the microwave light wave heating moving cavity 6, realizing microwave + light wave dual-mode heating, so that the surface of the material forms a caramelized taste. The double-layer stacked heat dissipation assembly 8 has an internally fixedly connected upper power supply 11, which is equipped with a protective shell to shield microwave interference. It provides suitable power to the microwave magnetron 9, cavity light wave tube 10, and heat exhaust fan 12. It also has overvoltage and overcurrent protection functions. When the circuit is abnormal, it automatically cuts off the power supply to ensure the safety of the equipment.

[0039] Specifically, the cavity light wave tube 10 inside the double-layer stacked heat dissipation assembly 8 serves as an auxiliary heating component. Powered by the power supply, the tungsten filament of the lamp tube heats up to generate infrared rays. The infrared rays penetrate the outer tube and irradiate the surface of the material, realizing dual-mode microwave and light wave heating. This can create a caramelized texture on the surface of the material and enrich the heating effect. The upper power supply 11 inside the assembly and the outer protective shell can shield microwave interference and provide suitable power for the microwave magnetron 9, the cavity light wave tube 10, and the heat exhaust fan 12. It also has overvoltage and overcurrent protection functions and automatically cuts off the power when the circuit is abnormal, effectively ensuring the safe operation of the equipment.

[0040] A heat exhaust fan 12 is fixedly connected inside the double-layer stacked heat dissipation component 8. The fan blades are rotated by a motor to generate directional airflow. The air inlet of the heat exhaust fan 12 faces the inside of the heat dissipation component, and the air outlet extends to the outside of the equipment through a pipe. When working, it can accelerate the air flow inside the double-layer stacked heat dissipation component 8, quickly exhaust the heat absorbed by the heat sink, and at the same time remove some of the heat from the top of the microwave light wave heating moving cavity 6, maintain the stable temperature of the external environment of the heating cavity, and avoid the surrounding components from being affected by high temperature. An intelligent electric controller 13 is fixedly connected to the outside of the heating cavity moving frame 3. The intelligent electric controller 13 has flame-retardant characteristics and is equipped with a touch screen and physical buttons on its surface. It is connected to other components through wires. It can be programmed automatically and can be freely set to microwave power, working time, working output count, etc., monitor the operating status of the equipment, and automatically alarm and stop when an abnormality occurs.

[0041] Specifically, the heat dissipation fan 12 inside the double-layer stacked heat dissipation component 8 generates directional airflow through the fan blades driven by the motor. The air inlet faces the inside of the component, and the air outlet extends to the outside of the equipment via a pipe. This accelerates the airflow inside the component, quickly dissipates the heat absorbed by the heat sink, and also removes the heat from the top part of the microwave light wave heating moving cavity 6, maintaining a stable external ambient temperature for the microwave light wave heating moving cavity 6 and preventing surrounding components from being affected by high temperatures. The intelligent electronic control unit 13 outside the heating cavity moving frame 3 has flame-retardant properties and is equipped with a touch screen display and physical buttons on its surface.

It can monitor the operating status of the equipment and automatically alarm and shut down when an abnormality occurs, taking into account both equipment protection and ease of operation.

[0042] The bottom of the microwave magnetron 9 is fixedly connected to the top of the microwave light wave heating moving cavity 6. A microwave sealing gasket is provided at the connection between the microwave magnetron 9 and the microwave light wave heating moving cavity 6 to prevent microwave leakage. This connection method ensures that the microwave energy generated by the microwave magnetron 9 is directly and losslessly transmitted to the microwave light wave heating moving cavity 6. At the same time, the design of the microwave magnetron 9 allows the microwaves to be evenly distributed in the cavity, avoiding local overheating of the material. In addition, the microwave magnetron 9 moves up and down synchronously with the microwave light wave heating moving cavity 6, which can keep the relative position of the microwave magnetron 9 and the microwave light wave heating moving cavity 6 fixed and prevent the microwave transmission path from deviating. The bottom of the light wave tube 10 inside the cavity is fixedly connected to the top of the microwave light wave heating moving cavity 6, and a high-temperature resistant sealant is provided between the light wave tube 10 and the microwave light wave heating moving cavity 6. The installation position of the light wave tube 10 inside the cavity is aligned with the center of the microwave light wave heating moving cavity 6, which can make the infrared rays evenly irradiate the surface of the material. Moreover, the light wave tube 10 inside the cavity moves up and down synchronously with the microwave light wave heating moving cavity 6, and the irradiation distance can be adjusted according to the height of the material to ensure stable heating effect.

[0043] Specifically, the bottom of the microwave magnetron 9 is connected to the top of the microwave light wave heating moving cavity 6. The microwave sealing gasket at the connection can prevent microwave leakage and ensure that microwave energy is directly and losslessly transmitted into the cavity. Its design also makes the microwaves evenly distributed, avoiding local overheating of the material. At the same time, the magnetron rises and falls synchronously with the heating cavity, keeping the relative position fixed and preventing the microwave transmission path from deviating. The bottom of the light wave tube 10 inside the cavity is connected to the top of the heating cavity. The light wave tube is aligned with the center of the heating cavity, so that infrared rays are evenly irradiated on the surface of the material.

[0044] The bottom of the upper power supply 11 is fixedly connected to the top of the microwave light wave heating moving cavity 6. The upper power supply 11 moves synchronously with the microwave light wave heating moving cavity 6, which can shorten the length of the wires between them, reduce power transmission loss, and at the same time prevent the wires from being pulled and worn due to the lifting and lowering of the heating cavity, thus extending the service life of the wires. The bottom of the exhaust fan 12 is fixedly connected to the top of the microwave light wave heating moving cavity 6. The exhaust fan 12 moves synchronously with the microwave light wave heating moving cavity 6, which can always maintain a fixed relative position with the heat dissipation components, ensuring that the airflow can flow accurately through the heat sink and maintain stable heat dissipation efficiency.

[0045] Specifically, the bottom of the upper power supply 11 is connected to the top of the microwave heating moving cavity 6, and moves synchronously with the microwave heating moving cavity 6. This can shorten the length of the wires to various electrical components, reduce power loss during transmission, and prevent the wires from being pulled and worn due to the raising and lowering of the microwave heating moving cavity 6, effectively extending the service life of the wires. Similarly, the bottom of the heat exhaust fan 12 is connected to the top of the microwave heating moving cavity 6, and moves synchronously with the microwave heating moving cavity 6.

[0046] The implementation principle of this application embodiment is as follows: First, the microwave light wave heating moving cavity 6 is made of stainless steel in a cylindrical or cuboid structure. Microwaves are uniformly reflected and distributed within the cavity. Combined with its internal integrated microwave reflection structure, this further ensures uniform microwave energy diffusion. The microwave magnetron 9 is fixed to the top of the microwave light wave heating moving cavity 6, and the generated microwave energy can be efficiently transmitted into the cylindrical or cuboid cavity of the microwave light wave heating moving cavity 6 to act on the food. Second, the bottom frame 1 supports four material trays 2. The material trays 2 are made of high-temperature resistant, microwave-penetrable, and safe materials. The cylinder at the bottom of the material tray 2 adjusts the height of the material tray 2, so that the food is precisely placed in the optimal heating zone within the cavity. The lifting device 5 drives the microwave light wave heating moving cavity 6 to dock with two of the material trays 2, forming a seal with the help of the sealing ring 7. The cavity prevents microwave leakage while ensuring concentrated energy. Two cylinders 4 drive the bottom of the moving frame 3 of the heating cavity. By sliding laterally, the two material trays 2 can be alternately loaded, effectively reducing material waiting time and significantly improving production efficiency. During heating, the improved material handling efficiency is superior to the inconvenience of fixed material handling in a single cavity. With multiple sets of one cavity, the material trays 2 are matched in a one-to-two ratio, which further improves the working and production efficiency of the equipment. The exhaust fan 12, together with the double-layer superimposed heat dissipation component 8, promptly removes excess heat from the cavity to avoid local overheating. The intelligent electronic control unit 13 realizes automatic control programming and can adjust the microwave power and working time to ensure stable energy output. When the material trays 2 of the two cavities work alternately, all components work together to maintain a consistent heating environment, ultimately achieving efficient and uniform heating.
