Description

Technical Field

[0001] This utility model relates to the field of food heating and cooking, specifically a food heating device with a rotating mechanism. Background Technology

[0002] Food heating appliances are a common device in food cooking, using electric or gas heating on a fixed stove to heat and cook food. With social progress and the ever-increasing pace of life, people have higher and higher demands for quick and convenient eating, which has led to the emergence of food container heating devices.

[0003] Chinese patent document CN111972997A discloses a convenient heating structure for a takeout container. It utilizes a compartmentalized structure to separate different types of food and heats each portion through a bottom heating layer. While this heating structure simplifies the food heating process to some extent, it still suffers from two technical drawbacks:

[0004] Firstly, while the aforementioned zoned heating method allows for individual heating and cooking of ingredients, the ingredients remain stationary within each zone, resulting in uneven heat distribution within each zone. This leads to inconsistent heating levels and times, significantly impacting the overall heating effect.

[0005] Secondly, because the food remains stationary within the compartments, the food at the bottom absorbs a significant amount of heat generated by the heating element. This not only prevents the food at the top of the compartments from being heated or cooked properly, but also causes the food at the bottom to burn, affecting the edibility of the food in the meal box. Utility Model Content

[0006] In order to overcome the technical defects of existing food container heating devices, this utility model provides a food heating device with a rotary mechanism that provides uniform heating and strong stability.

[0007] To achieve the above objectives, this utility model provides a food heating device with a rotating mechanism, which mainly includes a housing, a heating component, and a driving mechanism. The heating component is located inside the housing and is movably connected to the housing, and can rotate around an axis within the housing. The driving mechanism is fixedly mounted on the housing and can rotate in either the forward or reverse direction under the control of a circuit controller. A rotating shaft is also fixed to the heating component, which is connected to the driving mechanism to enable the heating component to rotate within the housing under the drive of the driving mechanism.

[0008] This application optimizes the above-described structure. The drive mechanism includes a motor, a drive wheel, a transmission wheel, and a transmission belt. The motor is fixedly mounted on the housing, with its output shaft extending outside the housing. The drive wheel is coaxially fixed to the motor's output shaft, rotating with the output shaft during motor operation. The transmission wheel is mounted on a rotating shaft and coaxially fixed to it. The axes of the transmission wheel and the drive wheel are parallel to each other, and their positions correspond. The transmission belt is fitted onto the drive wheel and the transmission wheel, allowing the motor to drive the rotating shaft to rotate together during operation.

[0009] This application further refines the above structure, adding at least one steering sensor to the housing. The steering sensor is fixed to the housing and corresponds to the direction of movement of the drive belt. The drive belt also has a protrusion fixed to it, which triggers the steering sensor to operate when the drive belt moves.

[0010] This application further optimizes the above structure by providing two steering sensors on the housing, which are respectively located on both sides of the transmission belt, so that the steering sensors can be triggered to work when the transmission belt moves in both directions under the drive of the motor.

[0011] This application optimizes the above-described structure by adding a positioning sleeve to the housing. The positioning sleeve is fixed to the housing and located on the outer side corresponding to the position of the transmission wheel to ensure the axial positional stability of the transmission wheel during operation.

[0012] This application optimizes the above-described structure. The heating assembly includes an upper cover, a lower cover, and an electromagnetic coil. The upper and lower covers are positioned correspondingly and are fastened together. The connection between the upper and lower covers forms a cavity for placing the food container. The electromagnetic coil is fixed to both the upper and lower covers and heats the food inside the container when energized.

[0013] This application further optimizes the above structure, with the pivot comprising an upper half-shaft and a lower half-shaft. The upper half-shaft is fixed to the upper cover, and the lower half-shaft is fixed to the lower cover, and the upper and lower half-shafts are fixed by a snap-fit ​​connection to form the pivot.

[0014] This application further refines the above structure, adding a positioning plate to the housing, which is fixed together with the housing. The positioning plate is sleeved on the upper and lower half-shafts, allowing the upper and lower half-shafts to extend out of the housing for radial and axial positioning of the upper and lower half-shafts.

[0015] This application further optimizes the above structure by adding rotating blocks on the outer sides of the upper and lower covers. The rotating blocks are located on opposite sides of the rotating shaft and are rotatably connected to the housing. A rotating mechanism is formed between the rotating blocks and the housing to enable smooth rotation of the heating assembly within the housing.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. In this utility model of a food heating device with a rotating mechanism, a drive mechanism is used to drive the heating component to rotate in either the forward or reverse direction within the housing. Firstly, the rotation of the heating component causes the food inside the food container to tumble during heating, resulting in more even and stable heating of the food and improving the reliability of cooking within the heating component. Secondly, because the food is constantly tumbling during heating, prolonged contact between the food and the container wall is avoided, effectively preventing overheating and scorching.

[0018] 2. In the food heating device with a rotating mechanism of this utility model, the motor is rotated forward or backward by triggering a direction sensor. This structure not only ensures that the food is constantly turned inside the food container, but also prevents the food container from accidentally opening or the food from falling out due to poor connection or sealing performance when it rotates, thus improving the stability of the heating device during operation.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The applicant hereby emphasizes that the following embodiments are one or more examples that can realize the technical solutions of the present utility model, obtain the corresponding technical effects, and solve the corresponding technical problems, but do not mean that the protection scope of the technical solution only includes the following embodiments.

[0029] according to Figures 1 to 8 As shown, the food heating device with a rotating mechanism of this utility model mainly includes a housing 1, a heating element 2, and a driving mechanism 3. The heating element 2 is disposed inside the housing 1 and is rotatably connected to the housing 1 via an axis, allowing the heating element 2 to continuously rotate the food inside the food container during heating. The driving mechanism 3 is mounted on the housing 1, located on the outside of the housing 1, and fixed to the housing 1. Driven by an external circuit controller, the driving mechanism 3 can rotate in either the forward or reverse direction. A rotating shaft 4 is also provided on the heating element 2, and the rotating shaft 4 coincides with the axis of rotation of the heating element 2 within the housing 1. The rotating shaft 4 extends outside the housing 1 and is fixed to the heating element 2. Driven by the driving mechanism 3, the heating element 2 can rotate in either the forward or reverse direction within the housing 1 through the connection of the rotating shaft 4.

[0030] In one embodiment of this utility model, the drive mechanism 3 consists of a motor 31, a drive wheel 32, a transmission wheel 33, and a transmission belt 34. The motor 31 is mounted on and fixed to the housing 1. The output shaft of the motor 31 extends outside the housing 1 and is coaxially fixed to the drive wheel 32. Therefore, the motor 31 can be mounted inside or outside the housing 1, as long as the motor 31 shaft is coaxially fixed to the drive wheel 32 outside the housing 1. The transmission wheel 33 is mounted on the rotating shaft 4 and coaxially fixed to it. The transmission belt 34 is respectively sleeved on the drive wheel 32 and the transmission wheel 33 to transmit the rotational power of the drive wheel 32. In this embodiment, the transmission wheel 33 and the drive wheel 32 are arranged with their axes parallel to each other, and their radial positions correspond to each other, so that the transmission belt 34 can smoothly sleeve on the drive wheel 32 and the transmission wheel 33 and play a good power transmission role between them. In this embodiment, the drive wheel 32 and transmission wheel 33 can be gears, and the transmission belt 34 can be a belt with teeth on the inside. Normal operation is achieved through the meshing of the drive wheel 32 and transmission wheel 33 with the teeth on the inside of the belt. Of course, the same function can be achieved using common pulley and belt combinations.

[0031] In another embodiment of this utility model, at least one steering sensor 11 is also provided on the housing 1. The steering sensor 11 is fixed to the housing 1 and electrically connected to an external circuit controller to trigger the forward or reverse rotation of the motor 31. The transmission belt 34 also has a protrusion 35, which is fixedly connected to the transmission belt 34. It can be installed separately on the transmission belt 34 or integrally formed with the transmission belt 34. The protrusion 35 and the steering sensor 11 are positioned corresponding to each other, and the steering sensor 11 can be triggered when the transmission belt 34 moves. In this embodiment, the steering sensor 11 can be a micro switch that contacts the protrusion 35, or it can be an inductive switch that can be covered by the protrusion 35. It can be installed outside or inside the housing 1 according to actual needs, and both can realize the forward or reverse rotation of the motor 31 triggered by the steering sensor 11.

[0032] In another embodiment of this utility model, two steering sensors 11 are provided, and are respectively located on both sides of the transmission belt 34. The two steering sensors 11 can be arranged on the left and right sides of the transmission belt 34, or on the top and bottom sides. Their function is that one of them triggers the motor 31 to rotate in the forward or reverse direction, and the other triggers the motor 31 to rotate in the reverse direction.

[0033] In another embodiment of this utility model, a positioning sleeve 12 is also provided on the outer side of the transmission wheel 33. The positioning sleeve 12 is fixed together with the housing 1, and limits the axial movement of the transmission wheel 33 without affecting its rotation, so as to ensure that the transmission wheel 33 will not have axial displacement during operation, thereby improving the stability and reliability of the linkage between the drive wheel 32 and the transmission wheel 33.

[0034] In one embodiment of this utility model, the heating component 2 includes an upper cover 21, a lower cover 22, and an electromagnetic coil 23. The upper cover 21 and the lower cover 22 are fastened together and form a receiving cavity 24 after connection. The receiving cavity 24 is used to hold the lunch box so that the heating component 2 can heat the food inside. The electromagnetic coil 23 is fixedly installed on the upper cover 21 and the lower cover 22, and is located outside the receiving cavity 24. The electromagnetic coil 23 is electrically connected to an external circuit controller and heats the food inside the lunch box by means of electromagnetic eddy currents after being energized. In this embodiment, the lunch box can be made of metal to achieve the heating of food by the electromagnetic coil 23. For the principle of heating food in a metal lunch box by the electromagnetic coil 23 and its control principle, those skilled in the art can refer to the detailed description in Chinese patent documents CN2206907Y, CN2349472Y, and CN1470805A, which will not be repeated here.

[0035] In another embodiment of this utility model, the rotating shaft 4 is composed of an upper half shaft 41 and a lower half shaft 42. The upper half shaft 41 is fixed together with the upper cover 21, while the lower half shaft 42 is fixed together with the lower cover 22. The upper half shaft 41 and the lower half shaft 42 are positioned correspondingly, both extending out of the housing 1, and are fixed together by a snap-fit ​​connection, thereby forming a complete rotating shaft 4.

[0036] In another embodiment of this utility model, the housing 1 is further provided with a positioning plate 13. The positioning plate 13 is fixed together with the housing 1 and sleeved on the outside of the upper half shaft 41 and the lower half shaft 42 to position the upper half shaft 41 and the lower half shaft 42 axially and radially, so as to prevent the shaft 4 from axially displaced when rotating and to prevent the upper half shaft 41 and the lower half shaft 42 from separating when rotating.

[0037] In another embodiment of this utility model, a rotating block 43 is also provided on the upper cover 21 and the lower cover 22. The rotating block 43 is located on the opposite side of the housing 1 along the axis of the rotating shaft 4, and is fixed together with the upper cover 21 and the lower cover 22. The rotating block 43 is coaxially arranged with the rotating shaft 4, so that it forms a linear axis with the rotating shaft 4 on both sides of the housing 1, to ensure the stability and reliability of the rotation of the upper cover 21 and the lower cover 22 within the housing 1.
