[0024] To address the technical problem that traditional refrigerators only have refrigeration and storage functions, requiring users to remove foods such as bread or bacon before heating them using a toaster or microwave, which is cumbersome and negatively impacts user experience, this application provides a heating device. The device includes a storage box, a heating component 2, and a moving component 3 on the refrigerator door 7. The storage compartment 1a of the storage box is connected to the heating space 2a outside the refrigerator door 7 via a connecting channel 1b. The moving component 3 directly moves the food from the storage compartment 1a to the heating space 2a, thus integrating refrigeration and heating functions and avoiding the cumbersome operation process.

[0025] Figures 1 to 6A heating device provided in this application embodiment is applied to a refrigerator. The refrigerator has a refrigerator door 7. The device is characterized by including a storage box, a heating component 2, and a moving component 3. The storage box is disposed on the refrigerator door 7 and has a storage slot 1a inside. The opening of the storage slot 1a is connected to the refrigerator compartment 7a. The heating component 2 includes a heating element that is rotatably disposed on the refrigerator door 7. The heating element and the refrigerator door 7 enclose a heating space 2a. A connecting channel 1b is opened on the side wall of the storage box near the refrigerator door 7. The refrigerator door 7 has a connecting channel 1b that connects the heating space 2a and the storage slot 1a. The moving component 3 is used to move the food in the storage slot 1a to the heating space 2a through the connecting channel 1b.

[0026] In this embodiment, the heating device of this application has a storage box inside the refrigerator door 7. The size and dimensions of the storage box are not limited. It is mainly used to store sliced ​​foods such as bread or bacon. The storage box forms a storage slot 1a with an open top. The storage slot 1a is directly connected to the refrigerator's refrigeration space for convenient food refrigeration and preservation. The storage box can be made of food-grade PP plastic, integrally injection molded, lightweight, low-cost, and resistant to low temperatures and impacts, suitable for the refrigerator environment; or it can be made of 304 stainless steel sheet stretched and formed, which has high strength and is easy to clean. The storage slot 1a is connected to the outside of the refrigerator door 7 through a connecting channel 1b on the side wall of the storage box. The connecting channel 1b is generally rectangular or elliptical. The opening of the connecting channel 1b is rounded to prevent food from being scratched when passing through the connecting channel 1b. The heating element of the heating assembly 2 is rotatably mounted on the outside of the refrigerator door 7. When closed, it together with the wall of the refrigerator door 7 encloses the heating space 2a. The heating space 2a is connected to the storage compartment 1a through the connecting channel 1b. The heating space 2a can hold one or more slices of bread or other food, which can be adjusted according to user needs. The heating element can be a microwave generator or a resistance wire. Since the heating of the resistance wire may affect the cooling effect of the refrigerator, the microwave generator will be more effective for heating food. The moving assembly 3 is arranged at the connecting channel 1b. It can move the food in the storage compartment 1a directly to the heating space 2a by rotating or sliding, so as to realize the connection between the functions of refrigeration and heating.

[0027] It should be noted that this application connects the storage compartment 1a and the heating space 2a by setting a connecting channel 1b. Food undergoes the entire process of "refrigeration-transfer-heating" sequentially on the inside and outside of the refrigerator door 7, eliminating the need for the user to open the door to take out or put in food, thus simplifying the operation steps. The rotating heating element allows it to flip outwards, which is convenient for putting in or taking out food and also allows for rapid heat dissipation after heating, reducing the heat transfer back to the refrigerator compartment. The overall structure is compact, directly utilizing the thickness direction of the refrigerator door 7 to integrate the heating function, without taking up extra kitchen counter space, thus expanding the refrigerator's usage scenarios.

[0028] Please see Figures 1 to 3In order to facilitate the movement of food in storage tank 1a to heating space 2a, the moving component 3 includes a rotating member 31, which is rotatably disposed in connecting channel 1b, and the outer peripheral wall of rotating member 31 protrudes at least partially from storage tank 1a and heating space 2a.

[0029] In one embodiment of this application, the core component of the moving assembly 3 is a cylindrical rotating member 31 arranged horizontally along the surface of the refrigerator door 7. Its two ends are directly embedded into the refrigerator door 7 or the heating assembly 2. A portion of the outer peripheral wall of the rotating member 31 extends into the storage compartment 1a, and another portion extends into the heating space 2a. When the user selects the heating function, the motor drives the rotating member 31 to rotate unidirectionally by a certain angle via a synchronous belt or gears. The cylindrical rotating member 31, through friction with the food or other transmission structures, pushes the food near the refrigerator door 7 outward from the storage compartment 1a, causing it to slide down along the connecting channel 1b onto the surface of the engaged heating element, ultimately being completely contained within the heating space 2a. The motor then stops.

[0030] By designing the rotating component 31 to simultaneously protrude from the outer periphery of the storage tank 1a and the heating space 2a, the entire process from feeding to conveying can be achieved with a single component, eliminating the need for complex mechanisms such as traditional push rods, slide rails, and gates. This significantly reduces the number of parts and is suitable for the compact layout of the narrow thickness of the door 22. The cylindrical rotating component 31 forms a flexible line contact with the food during rotation, ensuring that soft toast, crispy bacon, or folded cheese can be delivered smoothly without being crushed. The rotating component 31 can also be equipped with a structure that blocks the connecting channel 1b. When the rotating component 31 stops rotating, it forms a physical barrier, keeping the high-temperature air, oil mist, and moisture from the heating space 2a outside the door, preventing temperature fluctuations and cross-contamination of odors in the refrigerator compartment.

[0031] Please see Figure 4 To prevent unnecessary slippage between the rotating part 31 and the food, which would affect the efficiency of food movement, the outer peripheral wall of the rotating part 31 is provided with anti-slip teeth 311. When the rotating part 31 rotates, the anti-slip teeth 311 can be inserted into the surface of the food to drive the food from the storage tank 1a through the connecting channel 1b and into the heating space 2a.

[0032] In this embodiment, anti-slip teeth 311 are protruded at equal intervals along the axial and circumferential directions on the cylindrical surface of the rotating component 31. The teeth are triangular pyramids or arc-shaped blades, and the tooth height is slightly greater than the thickness of the food surface. The anti-slip teeth 311 are integrally injection molded with the rotating component 31 or formed by metal inserts. When the motor drives the rotating component 31 to rotate, the tips of the anti-slip teeth 311 are instantly pressed into the surface of the bread slice or meat slice, forming a micro-mechanical engagement. As the rotating component 31 continues to rotate, the food is forced to slide along the connecting channel 1b until it falls into the heating space 2a. After feeding is completed, the rotating component 31 stops rotating, which both isolates the heat and prevents the food from sliding back. Specifically, spirally distributed triangular pyramidal teeth with a tooth height of 1.5 mm and a apex angle of 60° can be integrally molded on the surface of the PPS plastic roller, which is suitable for soft foods such as toast; or 0.3 mm thick arc-shaped blades can be welded to the outer circumference of the 304 stainless steel roller, and the blade edge is electrolytically polished, which is suitable for frozen meat slices.

[0033] The anti-slip teeth 311 form a mechanical engagement between the rotating part 31 and the food, significantly increasing the tangential thrust. Even if the food surface is frosty, oily, or soft and fragile, it can prevent slippage, ensuring that each rotation accurately delivers a single item and improving the transfer success rate. The rounded corners of the teeth or the silicone coating reduce cutting damage to the food and maintain its shape. The anti-slip teeth 311 are integrated with the rotating part 31, eliminating the need for additional clamping components. The structure is simple and easy to clean. At the same time, when the teeth are facing upwards, the stop can also act as a gate to prevent heat backflow, further improving the reliability of the refrigerator door integrated heating system and the user experience.

[0034] Please see Figure 4 To further enhance the friction between the food and the rotating part 31, an anti-slip layer 312 is provided on the outer peripheral wall of the rotating part 31.

[0035] In one embodiment, a tubular anti-slip layer 312 is coaxially sleeved on the outer peripheral wall of the rotating component 31. The anti-slip layer 312 is made of food-grade rubber, silicone, or thermoplastic elastomer. The inner surface is fixed to the groove of the rotating component 31 by micro-interference or axial dovetail ribs. The outer surface is formed with grid knurling, annular ridges, or densely distributed hemispherical protrusions. The thickness is controlled within a range that can produce elastic deformation under pressure without significantly increasing the overall diameter. When the anti-slip layer 312 rotates with the rotating component 31 and comes into contact with food, its soft outer surface instantly conforms to the contour of the food, forming surface-to-surface friction. At the same time, the micro-protrusions on the outer surface further embed into the surface of the food, achieving secondary engagement, thereby uniformly transmitting the tangential thrust to the entire piece of food, so that it is stably pulled out of the storage slot 1a and sent into the heating space 2a through the connecting channel 1b.

[0036] The anti-slip layer 312 utilizes the deformation and rebound of elastic materials to form a continuous, soft, and high-friction interface between the rotating part 31 and the food. Even if the food surface is wet, oily, or covered with ice, it can significantly reduce the probability of slippage and ensure transfer efficiency. Its detachable sleeve structure means that after wear, only the thin-walled sleeve needs to be replaced, without scrapping the entire rotating part 31, reducing maintenance costs. At the same time, the anti-slip layer 312 isolates the metal or ceramic roller from direct contact with the food, avoiding abnormal noise and scratches, improving quietness and food hygiene and safety, thereby enhancing the reliability of the refrigerator door integrated heating device and the user experience.

[0037] Please see Figures 1 to 3 In order to ensure that the food can fit snugly against the opening of the connecting channel 1b and facilitate the food from the connecting channel 1b into the heating space 2a, the heating device includes a baffle 4. The baffle 4 is slidably disposed in the storage tank 1a and can abut against the food so that the food abuts against the refrigerator door 7 and blocks the connecting channel 1b.

[0038] In this embodiment, a guide groove is formed on the side or bottom wall of the storage tank 1a along the food pushing direction. The baffle 4 is embedded in the guide groove in the form of a slider or roller and can slide along the guide groove. The side of the baffle 4 facing the food is provided with an elastic tongue or a light spring, so that the baffle 4 always applies a lateral pushing force to the food in the direction of the refrigerator door 7, so that the food at the front edge is pressed tightly against the inner wall of the door and naturally covers the entrance of the connecting channel 1b. When the rotating component 31 rotates to push the food, the food at the front edge is pushed out, and the baffle 4 then moves forward to fill the gap, pressing the next piece of food against the door, keeping the entrance continuously blocked. Two T-shaped guide channels can be formed on the bottom wall of the storage tank 1a. The baffle 4 is a PPS plastic sliding plate with T-shaped ribs extending from the top and embedded in the guide channels. It is supported by a compression spring at the back and is suitable for vertically stacked toast slices or bacon and other foods. Alternatively, a stainless steel sliding rod can be embedded in the side wall of the storage tank 1a. The baffle 4 is a stainless steel sheet bent into a U-shaped clamp with a food-grade silicone pad attached inside. It can gently press the food with its own elasticity and is suitable for vertically placed bacon slices.

[0039] The baffle 4 of this application continuously applies lateral pressure to keep the food in contact with the inner wall of the refrigerator door 7 and to block the opening of the connecting channel 1b, thereby reducing the leakage of cold air from the refrigerator compartment and the backflow of heat from the heating compartment, and reducing energy consumption and temperature fluctuations. At the same time, it ensures that the front end of the food maintains a constant contact pressure with the rotating part 31 or the feeding teeth, further improving the reliability of the transfer and preventing slippage. The sliding baffle 4 can also automatically adapt to the amount of remaining food, eliminating the need for frequent adjustments by the user, improving the convenience of operation and the overall operational stability of the integrated heating device of the refrigerator door.

[0040] Please see Figures 1 to 3 In order to ensure that the baffle 4 can effectively abut against the food, an elastic element 5 is provided between the baffle 4 and the storage box. The two ends of the elastic element 5 elastically abut against the inner wall of the storage box and the baffle 4, respectively.

[0041] In one embodiment, the elastic element 5 is made of a linear compression spring, a wave spring, or elastic rubber, with one end abutting against the inner wall of the rear end of the storage box and the other end abutting against the center or two symmetrical points on the back of the baffle 4, so that the baffle 4 always applies a lateral pushing force towards the refrigerator door 7 to the food; guide ribs are provided parallel to the top or bottom wall of the storage box, and corresponding grooves are opened on the edge of the baffle 4, so that the baffle 4 slides along the guide ribs when the elastic element 5 extends or retracts, preventing deflection and jamming. For example, two cylindrical limiting posts are formed at the rear end of the storage box, each fitted with a stainless steel compression spring, and corresponding recesses are provided on the back of the baffle 4 for horizontally pushing the toast slices. The elastic element 5 allows the baffle 4 to automatically compensate for the gap caused by the reduction of food, ensuring that the food at the front is always in close contact with the refrigerator door 7 and blocks the connecting channel 1b, reducing the exchange of hot and cold air and maintaining a stable temperature in the refrigerator compartment; at the same time, constant pressure ensures that the food and the rotating part 31 or the feeding teeth maintain reliable contact, avoiding free rotation or slippage and improving the success rate of transfer; the elastic element 5 is hidden inside the storage box, does not take up extra food space, and the detachable design makes it easy to clean, enhancing the reliability of the integrated heating device of the refrigerator door and the user experience.

[0042] Please see Figures 1 to 3 In order to prevent the food from being affected by the refrigeration and preservation of the food in the refrigeration space during the heating process, the heating equipment also includes a heat insulation component 6, which is connected to the refrigeration door 7 and is located between the heating space 2a and the storage tank 1a.

[0043] In this embodiment, the heat insulation component 6 is formed into a rectangular partition adapted to the thickness of the steel plate layer of the refrigerator door 7. It is made of glass fiber reinforced PPS or double-layer vacuum-sealed stainless steel thin-walled box, with a pre-set annular groove embedded in the outer periphery of the door liner, and is fastened to the steel plate of the refrigerator door 7 by screws or clips. A material passage opening coaxial with the connecting channel 1b is opened in the center of the partition. The edge of the material passage opening is wrapped with a food-grade silicone lip. Under the pushing action of the baffle 4, the lip flexibly fits against the food surface to form a sliding seal. When heating, the heating element 21 is engaged, and the heat insulation component 6 physically separates the heating space 2a from the storage tank 1a. Heat can only be transferred through the material passage opening, and the lip remains in contact with the food as the amount of food decreases, reducing thermal bridging. The heat insulation component 6 forms a low thermal conductivity barrier between the heating space 2a and the storage compartment 1a, significantly reducing heat conduction and radiation to the refrigerator compartment and preventing the temperature in the refrigerator compartment from rising and causing a decrease in the preservation effect of other food items; the central lip slides and fits against the food, allowing the food to enter the heating space 2a smoothly while blocking the backflow of hot air, reducing condensation and odor transfer; the heat insulation component 6 is detachably connected to the refrigerator door 7, which is convenient for maintenance and replacement, and improves the energy efficiency, safety and long-term reliability of the integrated heating device in the refrigerator door.

[0044] Please see Figure 1 and Figure 3In order to ensure a tight connection between the door body 22 of the heating assembly 2 and the refrigerator door 7 when closed, the door body 22 is connected to the heating element, and the door body 22 is rotatably connected to the refrigerator door 7. The free end of the door body 22 is provided with a connector 221, and the refrigerator door 7 is provided with a mating part 71. The connector 221 and the mating part 71 are magnetically connected.

[0045] In one embodiment, the door 22 can be made of the same metal or plastic panel as the refrigerator door 7. The heating element is fixed on the inside by screws or buckles, and the side is rotatably connected to the outer surface of the refrigerator door 7 by a hidden hinge. The free end of the door 22 is embedded with a connector 221, which is a ferromagnetic sheet or a permanent magnet strip. The refrigerator door 7 is provided with a mating part 71 at the corresponding position. The mating part 71 is a permanent magnet strip or a ferromagnetic sheet. The surfaces of the two are flush, forming a surface-to-surface magnetic attraction. When the door 22 is rotated to the closed position, the connector 221 and the mating part 71 automatically align and generate a continuous magnetic force, so that the door 22 is pressed tightly against the refrigerator door 7, ensuring that the heating space 2a is sealed. For example, the free end of the door 22 has an injection-molded groove with an embedded neodymium iron boron magnetic strip, and the corresponding position of the refrigerator door 7 is attached with a galvanized steel plate, suitable for heating thin slices of food such as toast or bacon; or, stainless steel decorative pieces are wrapped around the edge of the door 22 as ferromagnetic connectors 221, and soft magnetic rubber strips are embedded in the refrigerator door 7, resulting in low noise when closing, suitable for use in the early morning at home. Both the connector 221 and the mating part 71 use mutually attractive permanent magnet strips, and soft silicone pads are added to the contact surface, providing strong magnetic force and cushioning the impact of closing the door. The magnetic connection allows the door 22 to close in one step without the need for additional locks, and the user can press or pull it open with one hand; the continuous magnetic force ensures that the door 22 and the refrigerator door 7 are tightly fitted throughout the entire heating cycle, reducing hot air leakage and energy loss, while preventing the door 22 from accidentally popping open and causing burns; the magnetic structure is hidden on the edge of the door 22, with a simple appearance, and the magnetic strips or iron pieces can be removed and replaced, making maintenance convenient and improving the safety, energy efficiency, and user experience of the integrated heating device in the refrigerator door.

[0046] Secondly, please refer to Figure 5 This application provides a refrigerator door 7, which includes the heating device provided in the first aspect of this application.

[0047] In this embodiment, the storage box is embedded in the inner liner of the door facing the refrigerator compartment 7a. The heating element of the heating component 2 is fixed to the outer surface of the door shell by a hinge. The connecting channel 1b passes through the refrigerator door 7 and coaxially connects the storage slot 1a and the heating space 2a. The heat insulation component 6 is clamped on the outer periphery of the connecting channel 1b. The baffle 4 and the elastic component 5 are arranged inside the storage box. By embedding the heating device into the refrigerator door 7, the refrigerator adds a rapid heating function while maintaining the original refrigeration function. Users do not need to purchase a toaster or microwave oven, saving kitchen space. The heat insulation effect of the heat insulation component 6 ensures that the temperature of the refrigerator compartment is hardly affected during heating, keeping the food fresh and improving the added value and market competitiveness of the product.

[0048] Thirdly, please refer to Figure 6 This application provides a refrigerator, including a refrigerator door 7 and a control system. The moving component 3 includes a motor and a rotating part 31. The motor is used to drive the rotating part 31 to rotate. The control system is electrically connected to the motor.

[0049] In one embodiment, the control system adds an offline voice module to the refrigerator's main control board. This module integrates a microphone array on the top of the door 22 shell and uses AEC (Acoustic Echo Cancellation) to collect the refrigerator's own compressor noise for noise reduction training. The module and the motor drive circuit share the same UART (Universal Asynchronous Receiver / Transmitter) interface. When the user speaks a preset wake-up word and command, such as "Good morning, heat up toast," the voice chip analyzes it locally and outputs the corresponding angle and speed parameters. The main control board immediately drives the motor to drive the rotating component 31 to complete the toasting process and simultaneously starts the heating component 2. Voice control allows users to operate the motor and heating component 21 without touching them even when their hands are occupied or oily, improving safety and convenience. The offline solution avoids uploading personal information and utilizes the refrigerator's original main control board resources without increasing additional hardware costs. By directly driving the motor and heating component 2 with voice commands, a one-stop "speak and bake" experience is achieved, enhancing the refrigerator's competitive advantage in intelligent design.
