Description

Technical Field

[0001] This application relates to the field of cooking equipment technology, and more particularly to a cooking device. Background Technology

[0002] With the increasing demand for roasted foods in daily life, such as roast chicken and roast duck, the roasting functions of cooking equipment have become more and more sophisticated, especially involving a method of hanging roasting.

[0003] In related technologies, cooking equipment includes an inner pot with a cooking cavity, and a heating plate is installed within the inner pot to heat food placed in the cooking cavity. The first end of the heating plate is rotatably connected to the inner pot, while the second end is detachably connected. When the second end of the heating plate is disconnected from the inner pot, the heating plate rotates relative to the inner pot around its first end under its own weight, thereby changing the position of the heat source.

[0004] However, in the relevant technologies, there is a technical problem that the heating plate collides with the wall of the cooking cavity during the process of the heating plate rotating relative to the inner pot by its own gravity. Summary of the Invention

[0005] In view of the above problems, this application provides a cooking device to solve the technical problem of collision between the heating plate and the wall of the cooking cavity when changing the heating position of the heating plate during hanging roasting of food, so as to improve the positional accuracy of the heating plate relative to the inner pot during the up-and-down flipping process, avoid collision between the heating plate and the wall of the cooking cavity, and improve the cooking reliability of the cooking device.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] This application provides a cooking device, including:

[0008] Inner pot, the inner pot having a cooking cavity open at the front;

[0009] A first drive mechanism is disposed at the top of the inner liner. The power output end of the first drive mechanism has a first drive shaft. The first drive shaft extends vertically and partially extends into the inner liner. The first drive shaft can rotate around its own axis.

[0010] A hanging grill is located inside the cooking cavity and is detachably connected to the first drive shaft so that the first drive shaft drives the hanging grill to rotate around its own axis.

[0011] A heating plate is disposed inside the inner liner, and the first end of the heating plate has a connecting terminal. The connecting terminal extends out of the inner liner and rotates and seals with the inner liner. The second end of the heating plate is a free end.

[0012] The second drive mechanism and the control unit are both located outside the inner liner. The control unit is electrically connected to the second drive mechanism to control the second drive mechanism to drive the heating plate to rotate up and down relative to the inner liner, so as to switch between at least the first gear, the second gear and the third gear.

[0013] When the heating plate is switched to the second setting, the heating plate is located on the outer periphery of the hanging grill and forms an angle with the side wall of the inner liner.

[0014] This configuration, controlled by the control unit, allows the heating plate to switch between three settings via the second drive mechanism. This enables the heat source to be positioned on the top or side walls of the cooking cavity, or at an angle to the side walls, accommodating the needs of hanging food with uneven volume distribution. Combined with the first drive mechanism rotating the hanging rack around its own axis within the cooking cavity, the food is heated 360° in a suspended position, ensuring even heating and preventing undercooked areas. This improves the cooking uniformity and reliability of the equipment. Furthermore, when the heating plate is precisely controlled at the second setting, its lower part is closer to the food below, allowing for more even heating of the larger lower volume food, preventing uneven cooking due to uneven volume distribution. Additionally, the second drive mechanism and control unit improve the precision of controlling the heating plate's rotation angle relative to the inner cavity, preventing contact between the heating plate and the inner wall of the cooking cavity, thus avoiding collisions and further enhancing the cooking reliability.

[0015] In some embodiments, when the heating plate is switched to the first setting, the heating plate is located above the hanging grill and arranged in a horizontal direction; when the heating plate is switched to the third setting, the heating plate is located on the outer periphery of the hanging grill and arranged in a vertical direction.

[0016] This allows it to adapt to different cooking needs and improves the precision of the heating plate's movement.

[0017] In some embodiments, when the heating plate is in the first position, the first drive shaft is located above the heating plate.

[0018] This design avoids the overlap between the movement path of the heating plate during the switching process between the first and second gear positions and the location of the first drive shaft, thereby preventing interference between the heating plate and the first drive shaft and improving the stability and reliability of the heating plate during the flipping process relative to the inner liner.

[0019] In some embodiments, when the heating plate is in the third position, the distance between the hanging grill and the heating plate along the front-back direction of the cooking cavity is less than the distance between the hanging grill and the opening.

[0020] This design brings food placed on the hanging grill closer to the heat source and away from the open external environment, reducing heat loss and improving cooking efficiency.

[0021] In some embodiments, the heating plate comprises at least two heating tubes, which are arranged in a concentric ring structure and are sequentially spaced from the inside to the outside along the radial direction of the cooking cavity. The outer periphery of the concentric ring structure is adapted to the cross-sectional profile of the cooking cavity, and the thermal radiation intensity of the concentric ring structure is uniformly distributed radially.

[0022] When the heating plate is in the first setting, the heat radiation areas of at least two heating tubes together cover the horizontal area at the bottom of the cooking cavity;

[0023] When the heating plate is in the third setting, the heat radiation areas of at least two heating tubes together cover the vertical cross-sectional area inside the cooking cavity.

[0024] This design increases the area of ​​the heating plate that radiates heat into the cooking cavity, thereby improving the uniformity of heating.

[0025] In some embodiments, a heating space is formed between the hanging grill and the top wall of the inner liner;

[0026] Each heating tube has an opening on one side adjacent to the rear sidewall of the inner liner. Both ends of each heating tube forming the opening are bent outward along the radial direction of the annular structure to form a bent section for connection with the connecting terminal. Each bent section is arranged sequentially at intervals along the width direction of the cooking cavity and is opposite to the heating space.

[0027] This design ensures that food suspended on the grill can also receive heat radiation from above, preventing the upper part of the food from being undercooked due to insufficient heat. This improves the evenness of heating the food by the heating plate and enhances the cooking effect of the equipment.

[0028] In some embodiments, the control unit includes a controller, a detection element, and a counting rod. The counting rod is drivenly connected to the heating plate to rotate synchronously with the rotation of the heating plate. Multiple counting structures are evenly arranged at intervals along the circumference of the counting rod. The detection element is fixed to the outer periphery of the counting rod and is signal-connected to the controller. The detection element is configured to detect the position of the counting structures. The controller controls the second drive mechanism to operate according to the detection signal of the detection element to precisely control the rotation angle of the heating plate.

[0029] This design improves the control precision of the heating plate's flip angle, thereby improving the positional accuracy of the heating plate within the cooking cavity and ultimately enhancing the applicability of the cooking equipment.

[0030] In some embodiments, the counting structure is a counting protrusion, and the detection element is a counting sensor.

[0031] This results in a simple structure, easy implementation, and low cost.

[0032] In some embodiments, the second drive mechanism has a first drive direction and a second drive direction, wherein the first drive direction and the second drive direction are opposite.

[0033] This configuration allows the heating plate to switch between the first, second, and third gears along the same motion path under the drive of the second drive mechanism. The driving method is simple and easy to implement.

[0034] In some embodiments, the second driving mechanism includes a drive motor and a power transmission component. The power output end of the drive motor has a second drive shaft with two opposite rotation directions. The power transmission component is connected between the second drive shaft and the heating plate. When the second drive shaft rotates about its own axis in different rotation directions, it drives the power transmission component to move in the first driving direction and the second driving direction, respectively, so as to at least drive the heating plate to rotate from the side wall of the inner liner to the top wall of the inner liner.

[0035] This design is simple and easy to implement. The extension and retraction length of the power transmission component in the first and second driving directions can be controlled by the transmission ratio between the second drive shaft and the power transmission component, thereby controlling the rotation angle of the heating plate relative to the cooking cavity. This allows the heating plate to be positioned not only at the first and second positions on the top and side walls of the inner pot, but also at the second position between the top and side walls of the inner pot, thus improving the positional accuracy of the heating plate in the cooking cavity.

[0036] In some embodiments, the power transmission component is a worm gear, and the second drive shaft has drive teeth that match the worm gear, the drive teeth meshing with the worm gear; the first end of the heating plate also has a force-receiving portion, the force-receiving portion being located between two adjacent connecting terminals;

[0037] When the second drive shaft rotates around its own axis, the worm moves along its own axis, moving towards or away from the force-bearing part to push against or release the force-bearing part, thereby driving the heating plate to rotate or stop rotating.

[0038] This design offers several advantages. Firstly, the meshing transmission between the worm gear and the drive gear is simple in structure and highly accurate in transmission. Secondly, the design of the force-bearing part increases the stress on the heating plate, reduces the damage rate of the heating plate, and extends the service life of the cooking equipment.

[0039] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the cooking equipment provided by the embodiments of this application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific implementation.

[0072] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0073] With the increasing demand for roasted foods in daily life, such as roast chicken and roast duck, the roasting functions of cooking equipment have become more and more sophisticated, especially involving a method of hanging roasting.

[0074] In some embodiments, the cooking device includes an inner pot with a cooking cavity, and a heating plate is disposed within the inner pot to heat food placed in the cooking cavity. A first end of the heating plate is rotatably connected to the inner pot, and a second end of the heating plate is detachably connected to the inner pot. When the second end of the heating plate is decoupled from the inner pot, the heating plate rotates relative to the inner pot around its first end under its own weight, thereby changing the position of the heat source. However, during the rotation of the heating plate relative to the inner pot under its own weight, a technical problem arises: the heating plate rotates from the top wall to the side wall of the cooking cavity, colliding with the side wall of the cooking cavity.

[0075] To address the aforementioned issues, this application provides a cooking device, including but not limited to ovens, steam ovens, and microwave-steam-roast combination ovens, which allows for the hanging roasting of food.

[0076] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0077] See attached image. Figure 1 A schematic diagram of the structure of a cooking device provided in an embodiment of this application; Figure 2 A schematic diagram of a heating plate in the third position provided in an embodiment of this application; Figure 3 for Figure 2 Cross-sectional view at point AA; Figure 4 A schematic diagram of a heating plate in the first position provided in an embodiment of this application; Figure 5 for Figure 4 Cross-sectional view at point BB.

[0078] like Figures 1 to 5 As shown, the cooking device 100 includes an inner pot 110, a first drive mechanism 120, a hanging rack 130, and a heating plate 140.

[0079] Among them, such as Figure 1 , Figure 2 and Figure 3 As shown, the inner pot 110 has a cooking cavity 111 with an open front side; for example, the inner pot 110 has one, two, three, four or more cooking cavities 111. When the inner pot 110 has multiple cooking cavities 111, the multiple cooking cavities 111 in the inner pot 110 can be divided according to different functions. The embodiments of this application take the improvement of one cooking cavity 111 in the inner pot 110 as an example for illustration.

[0080] Combination Figure 3 , Figure 8 As shown or in combination Figure 4 , Figure 9 As shown, the first drive mechanism 120 is disposed on the top of the inner liner 110. The power output end of the first drive mechanism 120 has a first drive shaft 121. The first drive shaft 121 extends vertically and partially extends into the inner liner 110. The first drive shaft 121 can rotate around its own axis.

[0081] In some embodiments, the first drive mechanism 120 includes a first drive motor 151 and an output shaft of the first drive motor 151. For example, the first drive shaft 121 is the output shaft; in another example, the first drive shaft 121 is another shaft-like component coaxially connected to the first drive shaft 121 to lengthen the output shaft and meet the transmission distance requirements between the first drive mechanism 120 and the desired drive component. Specifically, the first drive shaft 121 and the output shaft are fixedly connected, and the connection method includes, but is not limited to, welding, bonding, coupling connection, snap-fit ​​connection, etc.

[0082] like Figure 3 and Figure 5 As shown, the hanging grill 130 is located inside the cooking cavity 111 and is detachably connected to the first drive shaft 121, so that the first drive shaft 121 drives the hanging grill 130 to rotate around its own axis, thereby allowing the food loaded on the hanging grill 130 to rotate 360° around the axis of the hanging grill 130 in a hanging posture. That is, the food that needs to be cooked can be rotated 360° relative to the side wall of the cooking cavity 111 by the hanging grill 130.

[0083] For example, the detachable connection between the hanging grill 130 and the drive shaft includes, but is not limited to, bolt and nut connection, snap-fit ​​connection, pin connection, etc.

[0084] like Figure 6 and Figure 7 As shown, the heating plate 140 is set inside the inner liner 110, and then combined with... Figure 11 and Figure 13As shown, the first end 141 of the heating plate 140 has a connection terminal 1411. The connection terminal 1411 extends out of the inner liner 110 through the junction area of ​​the top wall and side wall of the inner liner 110 to electrically connect with the power supply cable or other power supply components to provide power to the heating plate 140, so that the electrical energy is converted into heat energy in the heating plate 140 to provide heat to the cooking cavity 111. The connection terminal 1411 rotates and seals with the inner liner 110, thereby sealing the inner liner 110 with the environment outside the inner liner 110, thereby preventing the ineffective loss of heat in the cooking cavity 111 and improving the cooking efficiency of the cooking equipment 100. In addition, the second end 142 of the heating plate 140 is a free end.

[0085] For example, the first end 141 of the heating plate 140 has at least two connection terminals 1411, and the number of connection terminals 1411 can be two, three, four, six, eight, etc.

[0086] Additionally, return Figure 3 , Figure 5 and combined Figure 8 and Figure 9 As shown, the cooking device 100 also includes a second drive mechanism 150 and a control unit (not shown in the figure). The second drive mechanism 150 and the control unit are both located outside the inner pot 110. The control unit is electrically connected to the second drive mechanism 150 to control the second drive mechanism 150 to drive the heating plate 140 to rotate up and down relative to the inner pot 110, so as to rotate and switch between at least the first gear, the second gear and the third gear, thereby meeting the cooking needs of different ingredients.

[0087] Furthermore, in combination Figure 8 , Figure 9 , Figure 11 , Figure 12 and Figure 13 As shown, the heating plate 140 has a rotating body 200 adjacent to the connection terminal 1411 (see figure). Figure 12 and Figure 13 As shown), the rotating body 200 is cylindrical, and the connecting terminal 1411 passes through the rotating body 200 radially. The rear side wall of the inner liner 110 is provided with a rotating cavity 112 that matches the rotating body 200 and is aligned with its axial direction (in conjunction with...). Figure 12 and 13 As shown), the rotating body 200 can deflect within the rotating cavity 112, so that the second end 142 of the heating plate 140 can swing up and down relative to the cooking cavity 111 under the drive of the second driving mechanism 150, thereby switching the position of the heating plate in the cooking cavity 111 to adapt to different cooking needs.

[0088] And such as Figure 13As shown, the outer peripheral wall of the rotating body 200 and the inner peripheral wall of the rotating cavity 112 are always in contact to form a surface seal, so as to reduce heat loss and improve the sealing reliability between the heating plate 140 and the inner liner 110.

[0089] For example, such as Figure 12 and Figure 13 As shown, the cross-sectional profile of the rotating body 200 is arc-shaped; the cross-sectional profile of the rotating cavity 112 is circular, so that the rotating body 200 and the rotating cavity 112 form a sliding connection between arc surfaces, thereby making the relative rotation between the two smoother and more stable.

[0090] like Figure 12 As shown, along the width direction of the inner liner 110, at least two spaced guide structures 210 are provided on the rear side wall of the inner liner 110. Each guide structure 210 includes two opposite guide portions 2101 recessed in opposite directions. The two guide portions 2101 together form a rotating cavity 112.

[0091] For example, each guide part 2101 is fixedly connected to the inner liner 110. The fixed connection methods include, but are not limited to, welding, bonding, snap-fit ​​connection, pin connection, etc.

[0092] And such as Figure 12 As shown, a clearance notch 1122 is formed between adjacent guide structures 210, through which the connection terminal 1411 can pass. When the heating plate 140 switches between the first and second gears, the rotating body 200 shields and seals the clearance notch 1122, so that the rotating body 200 and the multiple guide structures 210 are sealed and slidably connected. The structure is simple and easy to implement.

[0093] In other embodiments, the rear sidewall of the inner liner 110 has an installation notch. For example... Figure 12 and Figure 13 As shown, the cooking device 100 also includes two reinforcing plates 230, which are stacked and installed at the mounting notch and sealed to the mounting notch. Each reinforcing plate 230 has at least two guide portions 2101 recessed away from the other, so that each guide portion 2101 can be connected to the inner pot 110 through the corresponding reinforcing plate 230, thereby enhancing the connection strength and support strength between the inner pot 110 and the rotating body 200.

[0094] One of the two reinforcing plates 230 is located inside the inner liner 110, and the other is located outside the inner liner 110. The two reinforcing plates 230 are opposite each other and are detachably and sealed to the inner liner 110. In this way, the force from the reinforcing plates 230 can be dispersed from the inner and outer sides of the inner liner 110, thereby further improving the connection strength and support strength between the inner liner 110 and the reinforcing plates 230.

[0095] For example, each reinforcing plate 230 is fixedly connected to the inner liner 110. The fixed connection methods include, but are not limited to, snap-fit ​​connection, pin connection, bolt and nut connection, etc. A sealing ring can also be provided between each reinforcing plate 230 and the inner liner 110 to further improve the sealing reliability between the reinforcing plate and the inner liner.

[0096] It should be noted that when switching the heating plate 140 between the first, second and third gears, the hanging grill 130 needs to be removed from the drive shaft 121 first. After the heating plate 140 is switched to the desired gear, the hanging grill 130 can be installed back onto the drive shaft 121.

[0097] For example, such as Figure 5 and Figure 9 As shown, when the heating plate 140 rotates to the first setting, it is positioned above the hanging rack 130 and arranged horizontally for cooking small foods fixed near the top of the rack 130. When the heating plate 140 switches to the second setting, it is located on the outer periphery of the rack 130, forming an angle with the side wall of the inner liner. This is suitable for situations where the food has a small top and a large bottom, and the food near the bottom of the rack 130 is difficult to cook. By making the heating plate 140 form an angle with the side wall of the inner liner, it is closer to the bottom of the food, avoiding uneven cooking. Figure 3 and Figure 8 As shown, when the heating plate 140 is switched to the third position, the heating plate 140 is located on the outer periphery of the hanging grill 130 and arranged in the vertical direction. This is suitable for situations where the food is fixed on the hanging grill 130 and the volume of the food is uniform along the vertical direction of the hanging grill 130. In this way, the heating plate 140 is set on the periphery of the hanging grill 130. When the hanging grill 130 drives the food to rotate around its own axis, it can improve the uniformity of heating the food, thereby improving the cooking effect.

[0098] Of course, the heating plate 140 may include, but is not limited to, a first setting, a second setting, and a third setting. Between the first setting and the third setting, multiple settings may be provided so that the heating plate 140 has different tilt angles with the side wall of the inner pot, thereby meeting different cooking needs.

[0099] In addition, when the cooking device 100 is used for hanging roasting or grilling food, the control unit controls the second drive mechanism 150 to switch the heating plate 140 to the side wall of the inner cavity 110, i.e., the third setting, to improve the uniformity of food cooking. When the cooking device 100 is used for steaming, grilling, or microwave cooking food, the control unit controls the second drive mechanism 150 to switch the heating plate 140 to the top wall of the inner cavity 110, i.e., the first setting, to reduce the space occupied by the heating plate 140 in the width or front-back direction of the cooking cavity 111, so as to provide more cooking space for the food.

[0100] In another example, the control unit can control the second drive mechanism 150 to drive the heating plate 140 to switch between the top wall of the inner liner 110 and any one of the left, right, or rear walls of the inner liner 110, thereby changing the rotational connection position between the heating plate and the inner liner. However, the left and right side walls of the inner liner 110 have racks for placing baking trays. Therefore, when the third setting is the left or right side wall of the inner liner 110, interference may occur between the heating plate 140 and the racks. Therefore, this embodiment of the application describes the third setting as the rear wall of the inner liner 110 as an example.

[0101] In this embodiment, the control unit controls the second drive mechanism 150 to switch the heating plate 140 between the first, second, and third gear positions. This allows the heating source of the cooking device 100 to be located on the top wall or side wall of the cooking cavity 111, or at an angle to the side wall, to accommodate the hanging grilling requirements of foods with uneven volume distribution. Combined with the first drive mechanism 120 driving the hanging grill 130 to rotate around its own axis within the cooking cavity 111, the food can be heated in a hanging posture with 360° rotation, resulting in even heating and preventing localized undercooking. This improves the cooking uniformity and reliability of the cooking device 100. Furthermore, when the heating plate 140 is precisely controlled in the second gear position, the lower part of the heating plate 140 is closer to the food in the lower direction, allowing for more even heating of the larger food volume in the lower part, thus preventing uneven cooking due to uneven volume distribution. In addition, the arrangement of the second drive mechanism 150 and the control unit improves the control accuracy of the rotation angle of the heating plate 140 relative to the inner pot 110, so as to avoid the heating plate 140 from contacting the wall of the cooking cavity 111 in the inner pot 110, thereby avoiding collision between the two and further improving the cooking reliability of the cooking device 100.

[0102] Furthermore, such as Figure 5 and Figure 9As shown, when the heating plate 140 is in the first position, the first drive shaft 121 is located above the heating plate 140 to avoid the motion path formed by the heating plate 140 during the switching process between the first and second positions from overlapping with the position of the first drive shaft 121, thereby avoiding interference between the heating plate 140 and the first drive shaft 121 and improving the stability and reliability of the heating plate 140 during the flipping process relative to the inner liner 110.

[0103] In addition, such as Figure 3 and Figure 8 As shown, when the heating plate 140 is in the third position, the distance between the hanging rack 130 and the heating plate 140 along the front-back direction of the cooking cavity 111 is less than the distance between the hanging rack 130 and the opening, so that the food placed on the hanging rack 130 is closer to the heat source and further away from the external environment at the opening, reducing heat loss and improving cooking efficiency.

[0104] In some specific embodiments, such as Figure 10 and Figure 11 As shown, the heating plate 140 has at least two heating tubes 143, which are arranged in a concentric ring structure and are sequentially spaced from the inside to the outside along the radial direction of the cooking cavity 111 to improve the heating uniformity of the heating plate 140 to the cooking cavity 111 and improve the cooking effect.

[0105] For example, the heating plate 140 includes two, three, four or more heating tubes 143. This embodiment of the application will be described using the heating plate 140 including two heating tubes 143 as an example.

[0106] Furthermore, the outer periphery of the concentric ring structure is adapted to the cross-sectional profile of the cooking cavity 111, and the heat radiation intensity of the concentric ring structure is uniformly distributed radially to further increase the heat radiation area of ​​the heating plate 140 to the cooking cavity 111 and improve the heating uniformity.

[0107] When the heating plate 140 is in the first position, the heat radiation areas of at least two heating tubes 143 together cover the horizontal area at the bottom of the cooking cavity 111; when the heating plate 140 is in the third position, the heat radiation areas of at least two heating tubes 143 together cover the vertical cross-sectional area inside the cooking cavity 111, thereby making the size of the heating plate 140 fit the shape of the inner pot 110 while maximizing the heat radiation area of ​​the heating plate 140 and improving the cooking efficiency of the cooking device 100.

[0108] like Figure 7 and Figure 9 As shown, a heating space 113 is formed between the hanging grill 130 and the top wall of the inner liner 110. Combined with... Figure 5 , Figure 10 and Figure 11As shown, each heating tube 143 has an opening 1431 on one side of the inner liner 110. The two ends of each heating tube 143 forming the opening 1431 are bent outward along the radial direction of the annular structure to form a bent section 144 for connection with the connecting terminal 1411. Each bent section 144 is arranged sequentially at intervals along the width direction of the cooking cavity 111 and is opposite to the heating space 113, so that when the heating plate 140 is rotated to the third position, the bent section 144 can heat the heating space 113, so that the food suspended on the hanging rack 130 can also be radiated by heat from above, so as to avoid the food being undercooked due to insufficient heat on the upper part, thereby improving the heating uniformity of the food by the heating plate 140 and improving the cooking effect of the cooking equipment 100.

[0109] In addition, in some embodiments, the second drive mechanism 150 has a first drive direction and a second drive direction, which are opposite to each other. This allows the heating plate 140 to switch between the first, second, and third gears along the same motion path under the drive of the second drive mechanism 150, resulting in a simple and easy-to-implement driving method.

[0110] For example, the first driving direction and the second driving direction are curved. For instance, without changing the size of the second driving mechanism 150, by rotating and fixing the end of the second driving mechanism 150 away from the heating plate 140, and by turning the end of the second driving mechanism 150 close to the heating plate 140, the end of the second driving mechanism 150 close to the heating plate 140 acts on the heating plate 140. Then, the first driving direction and the second driving direction of the end of the second driving mechanism 150 close to the heating plate 140 are curved.

[0111] In another example, the first driving direction and the second driving direction are linear.

[0112] Specifically, in combination Figure 3 and Figure 8 As shown, or in combination Figure 5 and Figure 9 As shown, the second drive mechanism 150 includes a drive motor 151 and a power transmission component 152. The power output end of the drive motor 151 has a second drive shaft 153, which has two opposite rotational directions. The power transmission component 152 is connected to the second drive shaft 153. When the second drive shaft 153 rotates around its own axis in different rotational directions, it drives the power transmission component 152 to move in the first drive direction and the second drive direction, respectively, so as to at least drive the heating plate 140 to switch between the first gear, the second gear, and the third gear. The first drive direction and the second drive direction are two opposite directions extending along the axial direction of the power transmission component 152.

[0113] This configuration is simple and easy to implement. The extension and retraction length of the power transmission component 152 in the first and second driving directions can be controlled by the transmission ratio between the second drive shaft 153 and the power transmission component 152, thereby controlling the rotation angle of the heating plate 140 relative to the cooking cavity 111. This allows the heating plate 140 to be positioned not only at the first and third gear positions, but also at the second gear position with any included angle between the first and third gear positions. This improves the control accuracy of the heating plate 140's position in the cooking cavity 111 and enhances the cooking reliability of the cooking device 100.

[0114] In some embodiments, the following description illustrates the first driving direction and the second driving direction when the heating plate 140 switches from the third position to the first position, with the extension direction of the power transmission member 152 relative to the drive motor 151 being the first driving direction and the reverse direction being the second driving direction. The power transmission member 152 is rotatably connected to the portion of the first end 141 of the heating plate 140 located outside the inner liner 110, so that when the heating plate 140 needs to switch between the first, second, and third positions, and the power transmission member 152 needs to move along either the first or second driving direction, the power transmission member 152 always abuts against the portion of the first end 141 of the heating plate 140 located outside the inner liner 110. For example, the rotatable connection between the power transmission member 152 and the heating plate 140 can be a hole-shaft connection, a hinge connection, or the like.

[0115] In some other embodiments, the power transmission component 152 and the portion of the heating plate 140 located outside the inner liner 110 are in direct contact. In this case, the process of the heating plate 140 switching from the third gear to the first gear, from the third gear to the second gear, and from the second gear to the first gear is completed by the second drive shaft 153 driving the power transmission component 152 to move along the first drive direction. However, the process of the heating plate 140 switching from the first gear to the third gear, from the first gear to the second gear, and from the second gear to the third gear requires the heating plate 140 to automatically rotate back to the side wall of the inner liner 110 under its own gravity. Of course, during this process, the second drive shaft 153 retracts by the corresponding length along the second drive direction as the heating plate 140 rotates to the target gear.

[0116] For example, the power transmission component 152 is a worm gear, and the second drive shaft 153 has drive teeth that match the worm gear. The drive teeth mesh with the worm gear, and the meshing transmission between the worm gear and the drive teeth results in a simple structure and high transmission accuracy; additionally, as... Figure 8 , Figure 9 , combined Figure 10 , Figure 11As shown, the first end 141 of the heating plate 140 also has a force-receiving part 1412, which is located between two adjacent connecting terminals 1411. The force-receiving part 1412 can be a separately provided rod-shaped member, shaft-shaped member, etc. The provision of the force-receiving part 1412 increases the force strength of the heating plate 140. Compared with the worm gear directly acting on the connecting terminals 1411, it reduces the damage rate of the heating plate 140 and improves the service life of the cooking equipment 100.

[0117] When the second drive shaft 153 rotates around its own axis, the worm moves along its own axis, moving towards or away from the force-bearing part 1412 to push against or release the force-bearing part 1412, thereby driving the heating plate 140 to rotate or stop rotating, so that the heating plate 140 can switch between the first gear, the second gear and the third gear.

[0118] In addition, such as Figure 8 and Figure 9 As shown, the control unit includes a controller (not shown), a detection element 160, and a counting rod 161. The counting rod 161 is connected to the heating plate 140 and rotates synchronously with the rotation of the heating plate 140. Multiple counting structures are evenly arranged at intervals along the circumference of the peripheral wall of the counting rod 161. The detection element 160 is fixed to the outer periphery of the counting rod 161 and is signal-connected to the controller. The detection element 160 is configured to detect the position of the counting structures. The controller controls the second drive mechanism 150 to operate according to the detection signal of the detection element 160, so as to accurately control the rotation angle of the heating plate 140, improve the accuracy and reliability of the switching of the heating plate 140 between different settings, and effectively avoid direct contact between the heating plate 140 and the cavity wall of the cooking cavity 111, thus avoiding collisions and improving cooking reliability.

[0119] For example, the counting rod 161 is coaxially connected to the second drive shaft 153. The controller controls the drive motor 151 to rotate, so that the second drive shaft 153 drives the counting rod 161 to rotate. The detection element 160 identifies the number of counting structures on the counting rod 161 to calculate the rotation angle of the second drive shaft 153. Then, based on the transmission ratio between the second drive shaft 153 and the power transmission element 152, the extension distance of the power transmission element in the first or second drive direction is calculated, and the rotation angle of the heating plate 140 relative to the cooking cavity 111 is calculated. Therefore, by controlling the rotation of the drive motor 151 to control the rotation angle of the second drive shaft 153, the heating plate 140 can be precisely controlled at the second position, either the first or third position, or any position in between. This improves the positional accuracy of the heating plate 140 in the cooking cavity 111, thereby improving the applicability of the cooking device 100 to different foods.

[0120] For example, the counting structure can be a counting protrusion, a counting groove, etc.; the detection element 160 can be a counting sensor, such as a laser counting sensor, an image recognition counting sensor, a photoelectric counting sensor, an inductive counting sensor, a capacitive counting sensor, etc. The combination of the counting structure and the detection element 160 is simple in structure and easy to implement.

[0121] In another example, the counting rod 161 and the second drive shaft 153 are an integral structure, eliminating the need for intermediate connecting parts, thereby improving the connection accuracy between the two, which in turn improves the detection accuracy of the detection element 160, and further improves the positional accuracy of the heating plate 140 in the cooking cavity 111.
