[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the utility model, and cannot be interpreted as limiting the utility model.
[0025] In one embodiment, Figure 1-2 As shown, a heating mechanism 10 is used to heat a pot 20 of an automatic cooking machine. The pot 20 includes an opening, a pot wall and a pot bottom. Food materials are put into the pot 20 from the opening. The pot bottom is opposite to the opening. A rotating shaft 21 is provided on the pot bottom. The rotating shaft 21 drives the pot 20 to rotate around its axis. The pot wall is the area between the opening and the pot bottom of the pot 20. When cooking, the food materials in the pot 20 are in contact with the inner surface of the pot wall.
[0026] The heating mechanism 10 includes a mounting bracket and two heating coils 12. The mounting bracket includes an arc-shaped bottom plate 11 that matches the pot wall. The two heating coils 12 are respectively mounted on the arc-shaped bottom plate 11, that is, the two heating coils 12 are also respectively arranged opposite to the pot wall. The positions of the two heating coils 12 on the arc-shaped bottom plate 11 do not completely overlap, so that relative to one heating coil 12, the two heating coils 12 increase the coverage area of the pot wall, thereby increasing the heating area of the pot 20. In the case of a single heating coil 12, since the heating area of the pot wall by the heating coil 12 is limited, the temperature gradient of the pot wall may be large. However, by providing two heating coils 12, the heating area of the pot wall can be increased, the temperature gradient of the pot wall can be reduced, the heating can be more uniform, the cooking quality of the automatic cooking machine is improved, and the user experience is better.
[0027] In addition, the two heating coils 12 are respectively arranged on the pot wall through the mounting brackets, and do not need to pass through the pot bottom provided with the rotating shaft 21, so the installation is convenient. The heating coils 12 do not need to be provided with an additional avoidance structure for the rotating shaft 21 and other mechanisms. The two heating coils 12 have a simple structure, low cost, and are easy to promote and apply.
[0028] The heating coil 12 is usually a coil structure formed by cutting and bending a metal or alloy such as an iron core or a nickel-chromium alloy, and is used to provide a heating function in a cooker or a cooking machine after being powered on.
[0029] In other embodiments, more heating coils 12 may be provided according to actual heating range requirements, etc., to ensure uniform heating of the food in the pot 20 .
[0030] In one embodiment, one heating coil 12 is arranged on one side of another heating coil 12 along the direction of the axis of the rotating shaft 21, that is, the two heating coils 12 are located at different positions on the axis of the rotating shaft 21. When the pot 20 rotates around the axis of the rotating shaft 21, one heating coil 12 can heat the circumferential surface of the pot wall facing the portion thereof, and the two heating coils 12 at different positions on the axis of the rotating shaft 21 can heat a larger area of the circumferential surface of the pot wall, further expanding the heating area when the pot 20 rotates, and the food in the pot 20 is heated more evenly, and the final dish tastes better.
[0031] Furthermore, one heating coil 12 is arranged on one side of the other heating coil 12 along the rotation direction of the pot 20. That is, with the opening of the pot 20 as the upper end, the two heating coils 12 are neither arranged directly opposite each other up and down nor left and right, but are arranged diagonally. The pot 20 does not need to increase the height or diameter to match the two heating coils 12. The two heating coils 12 arranged in this way can be easily arranged directly opposite the pot wall of the original pot 20, saving design costs, and the overall size of the automatic cooking machine does not change much, saving space and improving the user experience.
[0032] In one embodiment, the positions of the two heating coils 12 partially overlap, and the overlapping area integrates the two heating coils 12, so the temperature output at this position is higher than that at other positions of the two heating coils 12, that is, the overlapping area is the high temperature zone of the heating mechanism 10, which increases the temperature range of the heating mechanism 10 and facilitates flexible adaptation to more cooking needs; the heating power of the high temperature zone is greater than that of other areas, which saves cooking time and improves cooking efficiency. The area of the high temperature zone can be changed by changing the area of the overlapping area to adapt to different needs.
[0033] In one embodiment, the mounting bracket further includes a buckle 13, the buckle 13 includes a connection portion and a plurality of buckle rods arranged in an array around the connection portion, the plurality of buckle rods are radially distributed from the connection portion to the surrounding of the connection portion, and the ends of the plurality of buckle rods away from the connection portion are fixed on the arc bottom plate 11, that is, the plurality of buckle rods are naturally bent with the curvature of the arc bottom plate 11, and the heating coil 12 is arranged between the arc bottom plate 11 and the buckle rods, that is, the heating coil 12 also forms a curved surface matching the pot wall. The heating coils 12 at different positions are at the same distance from the pot wall under the restriction of the mounting bracket, and the heating mechanism 10 heats the pot 20 more evenly and controllably. The radially distributed buckle rods can stably fix the heating coil 12 on the surrounding side of the pot wall with a small number of them, which is low in cost and good in effect.
[0034] In one embodiment, the ends of the multiple buckling rods close to the arc-shaped bottom plate 11 are concave to form multiple fixed grooves arranged at intervals, and the heating coil 12 is arranged in the multiple fixed grooves of the multiple buckling rods. The groove walls of the multiple fixed grooves can constrain the heating coil 12 to keep its original shape and prevent the heating coil 12 from deforming. At the same time, the heating coil 12 can be fixed to the surrounding side of the pot 20 to provide stable heating for the pot 20.
[0035] In one embodiment, the heating mechanism 10 further includes a plurality of magnetic conductive strips 14, which are arranged on the side of the heating coil 12 away from the arc bottom plate 11. When current passes through the heating coil 12, a magnetic field is generated. The magnetic field acts on the pot 20 and generates eddy currents in the pot 20 according to the principle of electromagnetic induction. The eddy currents cause the pot 20 to heat up at a high speed by itself, thereby heating the food in the pot 20. A plurality of magnetic conductive strips 14 are arranged on the side of the heating coil 12 away from the pot 20, so that the electromagnetic waves generated by the heating coil 12 are all absorbed by the magnetic conductive strips 14 and the pot 20 on both sides thereof, avoiding magnetic leakage and preventing harm to human health. Among them, the magnetic conductive strips 14 are usually made of magnetic materials, such as iron, nickel, cobalt, etc.
[0036] In one embodiment, the side walls of the multiple buckle rods are provided with multiple through mounting holes, and the magnetic conductive strip 14 is inserted into the mounting holes. The buckle rods cooperate with the arc bottom plate 11 to fix the heating coil 12, and fix the magnetic conductive strip 14 through the mounting holes provided thereon, with a simple structure and high integration.
[0037] In one embodiment, Figure 4 As shown, the heating mechanism 10 also includes a heating core 15, and one heating core 15 is electrically connected to two heating coils 12. The outputs of the two heating coils 12 can be uniformly controlled and coordinated, which makes it easier to achieve a more uniform heating effect, saves the cost of using multiple heating cores 15, and occupies less space.
[0038] In one embodiment, Figure 3-4 As shown, an automatic cooking machine includes a pot 20, a housing 30 arranged on the periphery of the pot 20, and the heating mechanism 10 in the above-mentioned embodiment, and an arc bottom plate 11 is fixed in the housing 30, and the housing 30 covers the periphery of the pot 20 and the heating mechanism 10, which can reduce the heat dissipation of the heating mechanism 10 and the pot 20, and play a certain heat preservation effect. A gap is set between the arc bottom plate 11 and the pot wall to facilitate the rotation of the pot 20 or the heating mechanism 10, so that the heating is more uniform.
[0039] Specifically, the bottom of the pot 20 is fixedly connected to the shaft 21, and the motor can drive the shaft 21 to rotate by rotating the gear, thereby driving the pot 20 to rotate, so that the pot 20 is heated more evenly. The arc bottom plate 11 can be fixedly connected to the housing 30 through a pair of angle steels 32 and other connecting parts.
[0040] In one embodiment, the heating mechanism 10 may further include a heat dissipation device, which is fixed on the housing 30 directly opposite the heating coil 12. The heating coil 12 will generate high temperature when it outputs high power for a long time, and the high temperature will affect the life and electrical performance of the heating coil 12. The heat dissipation device can help the inside and surface of the heating coil 12 to dissipate the residual heat faster, maintain the heating coil 12 within a suitable working temperature, and protect the heating coil 12. The heat dissipation device can be a heat dissipation fan 31, a heat sink, etc.
