The head 300 has a head 300 docking side facing the support mechanism, the support mechanism has a support mechanism docking side facing the head 300, the head 300 docking side is opposite to the support mechanism docking side, the head 300 docking side is provided with a rotating shaft, and the head 300 is rotatably connected to the support mechanism through the rotating shaft.

[0122] In one embodiment, see Figure 1 The support mechanism includes a first support member 510 and a second support member 520 that are arranged opposite to each other. The machine head 300 is rotatably connected to the first support member 510 and / or the second support member 520 through a rotating shaft and is located between the first support member 510 and the second support member 520. The first support member 510 and the second support member 520 are respectively connected to the two sides of the base 110. The first support member 510 is located on the first side of the cooking device, that is, the first side of the machine head 300, and the second support member 520 is located on the second side of the cooking device, that is, the second side of the machine head 300. The first support member 510 and the second support member 520 can be column structures.

[0123] In this embodiment, see Figure 5-Figure 10 The rotating shaft includes a first rotating shaft portion 530, which is disposed on the first supporting member 510 side, i.e., the first side of the handpiece 300. The first end of the first rotating shaft portion 530 is connected to the handpiece 300, and the handpiece 300 can rotate synchronously with the first rotating shaft portion 530. The second end of the first rotating shaft portion 530 is connected to the rotation driving mechanism 400, and the rotation driving mechanism 400 is used to drive the first rotating shaft portion 530 to rotate, thereby driving the handpiece 300 to rotate.

[0124] The rotation driving mechanism 400 may be fixed on the first supporting member 510 .

[0125] In one embodiment, see Figure 5The rotation drive mechanism 400 includes a main drive member 410 and a transmission assembly 420. The main drive member 410 is cooperatively connected with the transmission assembly 420. The transmission assembly 420 is connected to the first rotating shaft 530. The driving force provided by the main drive member 410 is transmitted to the first rotating shaft portion 530 through the transmission assembly 420 to drive the first rotating shaft portion 530 to rotate.

[0126] The main driving member 410 may include a gear drive motor, the transmission assembly 420 includes a driving gear 421 and a shaft gear 422, the gear drive motor is electrically connected to the main control board, the output shaft of the gear drive motor is connected to the rotating shaft hole of the driving gear 421, the driving gear 421 rotates synchronously with the output shaft of the gear drive motor, the driving gear 421 is meshed with the shaft gear 422, and the rotating shaft hole of the shaft gear 422 is connected to the second end of the first shaft portion 530. When the main control board outputs a control signal to the gear drive motor, the gear drive motor can drive the driving gear 421 to rotate by rotating the output shaft under the drive of the control signal. Since the driving gear 421 is meshed with the shaft gear 422, the rotation of the driving gear 421 will drive the shaft gear 422 to rotate. Since the rotating shaft hole of the shaft gear 422 is connected to the second end of the first shaft portion 530, the rotation of the shaft gear 422 will drive the first shaft portion 530 to rotate. That is, through the mutual cooperation between the gear drive motor and the drive gear 421, the shaft gear 422, and the first shaft portion 530, the automatic rotation of the first shaft portion 530 can be controlled, and then the head 300 can be flipped to the desired working position without manually flipping the head 300, thereby saving labor costs.

[0127] The gear drive motor can be fixedly connected to the first support member 510 by screws, and the wires in the gear drive motor can be connected to the main control board through the wire vias on the first support member 510 and the base 110 .

[0128] See also Figure 6 and Figure 7 The rotating shaft hole of the driving gear 421 is provided with a flat hole 421a, and the end of the output shaft of the gear driving motor is provided with a flat part 411 adapted to the flat hole 421a. Through the mutual cooperation between the flat hole 421a and the flat part 411, the driving gear 421 can rotate synchronously with the output shaft of the gear driving motor.

[0129] See also Figure 8 and Fig. 9The outer surface of the first rotating shaft portion 530 is connected with a plurality of ribs 531, and the rotating shaft hole of the rotating shaft gear 422 is provided with a plurality of slots 422a adapted to the plurality of ribs 531. Through the mutual engagement of the ribs 531 and the slots 422a, the first rotating shaft portion 530 and the rotating shaft gear 422 can be formed into a whole, that is, the relative position relationship between the two is ensured to remain unchanged, and when the rotating shaft gear 422 rotates, the first rotating shaft portion 530 can rotate synchronously with the rotating shaft gear 422. Among them, the second end of the first rotating shaft portion 530 can be fixed to the rotating shaft gear 422 by a screw, further ensuring that the first rotating shaft portion 530 will not be separated from the rotating shaft gear 422. In addition, the first side of the machine head 300 is also provided with a slot 422a that is compatible with the rib 531 on the outer surface of the first rotating shaft portion 530. The first end of the first rotating shaft portion 530 and the first side of the machine head 300 can also be connected by the matching snap connection between the rib 531 and the slot 422a, that is, the synchronous rotation of the first rotating shaft portion 530 and the machine head 300 can be achieved. Fig.10 Schematic diagram of the connection structure between the first rotating shaft portion 530 and the rotating shaft gear 422.

[0130] The shaft gear 422 can be made of a material with good wear resistance, such as POM material (polyoxymethylene resin).

[0131] In this embodiment, see Fig.11 The shaft may further include a second shaft portion 540, which is disposed on the second support member 520 side, i.e., the second side of the handpiece 300. The first end of the second shaft portion 540 is connected to the handpiece 300, and the handpiece 300 can rotate with the second shaft portion 540, and the second end of the second shaft portion 540 is rotatably connected to the second support member 520.

[0132] When the rotary drive mechanism 400 drives the first rotating shaft portion 530 to rotate, in order to make the entire head 300 follow the first rotating shaft portion 530 to rotate normally, a second rotating shaft portion 540 is set on the second side of the head 300, and the relative position between the second rotating shaft portion 540 and the head 300 remains unchanged. At the same time, the second rotating shaft portion 540 and the second support member 520 are in a rotational connection relationship, that is, when the head 300 rotates driven by the first rotating shaft portion 530, the second rotating shaft portion 540 can rotate synchronously, that is, the first rotating shaft portion 530, the head 300 and the second rotating shaft portion 540 can rotate synchronously relative to the supporting mechanism.

[0133] Specifically, see Fig.11The first end of the second rotating shaft portion 540 can be connected to the second side of the machine head 300 by means of ribs and slots. An end cover 541 and a transition piece 542 are arranged between the second end of the second rotating shaft portion 540 and the second support member 520. The end cover 541 and the second rotating shaft portion 540 can be connected by snaps or screws. The end cover 541 and the transition piece 542 can be connected by means of ribs and slots. The transition piece 542 and the second side of the machine head 300 can also be fixedly connected by screws. The transition piece 542 and the second support member 520 can be rotatably connected by means of an axial hole connection.

[0134] In this embodiment, only one rotating shaft may be provided, and the first rotating shaft portion 530 and the second rotating shaft portion 540 are respectively located at two ends of the same rotating shaft. Alternatively, two rotating shafts are provided, namely the first rotating shaft and the second rotating shaft, the first rotating shaft is provided on the first support member side, the second rotating shaft is provided on the second support member, the first rotating shaft includes the first rotating shaft portion 530, and the second rotating shaft includes the second rotating shaft portion 540.

[0135] In one embodiment, the cooking device further includes a limiting structure, which is used to limit the head 300 from continuing to rotate when it rotates along the first rotation direction to the first extreme rotation position, and to limit the head 300 from continuing to rotate when it rotates along the second rotation direction to the second extreme rotation position, and the first rotation direction is opposite to the second rotation direction. When the head 300 rotates along the first rotation direction around the rotation axis, the position of the head 300 gradually approaches the first working position, and when the head 300 rotates along the second rotation direction around the rotation axis, the position of the head 300 gradually approaches the second working position. For details, please refer to Fig.12 and Fig.13 , the first rotation direction is Fig.12 and Fig.13 In the clockwise direction of the viewing direction shown, the first limit rotation position of the corresponding head 300 is shown in FIG. Fig.13 Correspondingly, the second rotation direction is Fig.12 and Fig.13 In the counterclockwise direction of the viewing direction, the corresponding second limit rotation position of the head 300 is shown in FIG. Fig.12 The first rotation direction is that the second working position rotates toward the first working position, and the second rotation direction is that the first working position rotates toward the second working position.

[0136] The setting of the limiting structure can prevent the head 300 from rotating 360 degrees relative to the supporting mechanism, thereby preventing the wires and / or signal lines from being entangled due to the rotation of the head 300, and thereby preventing the wires and / or signal lines from being damaged due to local force concentration, thereby ensuring the stability of the electrical connection and signal connection in the cooking equipment.

[0137] It is understandable that the setting of the limiting structure enables the head 300 to rotate only between the first limit rotation position and the second limit rotation position. More specifically, Fig.12 and Fig.13 In the illustrated embodiment, the first working position of the machine head 300 is the same as the first extreme rotation position, and the second working position of the machine head 300 is the same as the second extreme rotation position. In other words, the rotation angle of the machine head 300 from the first extreme rotation position to the second extreme rotation position is 180 degrees. Of course, in another feasible embodiment, the first working position of the machine head 300 is not limited to coincide with the first extreme rotation position, but can be located between the first extreme rotation position and the second extreme rotation position. Similarly, the second working position is not limited to coincide with the second extreme rotation position, but can be located between the first extreme rotation position and the second extreme rotation position.

[0138] In this embodiment, the limiting structure may include a first limiting portion 610 and a second limiting portion 620 provided on the rotating shaft, and a first stop portion 630 and a second stop portion 640 provided on the supporting mechanism. The first limiting portion 610 matches with the first stop portion 630 to limit the head 300 from continuing to rotate when it rotates along the first rotation direction to the first limit rotation position, and the second limiting portion 620 matches with the second stop portion 640 to limit the head 300 from continuing to rotate when it rotates along the second rotation direction to the second limit rotation position.

[0139] In one embodiment, see Fig.12 and Fig.13 The limiting structure can be arranged on the second side of the nose 300 , wherein the first limiting portion 610 and the second limiting portion 620 can be arranged on the second rotating shaft 540 , and the first stopping portion 630 and the second stopping portion 640 can be arranged on the second support member 520 .

[0140] The limiting structure may include a limiting block provided on the second rotating shaft portion 540 and a stop block provided on the second supporting member 520, the first limiting portion 610 and the second limiting portion 620 are respectively the ends of the limiting block along the circumferential direction, and the first stop portion 630 and the second stop portion 640 are respectively the ends of the stop block. In other words, in this embodiment, the first limiting portion 610 and the second limiting portion 620 are integrally formed, and the first stop portion 630 and the second stop portion 640 are integrally formed. Of course, it can be understood that in other embodiments, the first limiting portion 610 and the second limiting portion 620 can also be independently provided, and the first stop portion 630 and the second stop portion 640 can also be independently provided.

[0141] The first limiting portion 610 has a first limiting surface, the second limiting portion 620 has a second limiting surface, the first stop portion 630 has a first stop surface, and the second stop portion 640 has a second stop surface. When the machine head 300 is located at the first extreme rotation position, the second limiting surface and the second stop surface are coplanar, and the first limiting surface abuts against the first stop surface; when the machine head 300 is located at the second extreme rotation position, the first limiting surface and the first stop surface are coplanar, and the second limiting surface and the second stop surface abut against each other.

[0142] Optionally, the limit block is fan-shaped, and / or the stop block is fan-shaped. It is understandable that in other feasible embodiments, the limit block and the stop block are not limited to being fan-shaped, and can also be any other regular or irregular shape.

[0143] It is understandable that, in another feasible embodiment, the limiting structure is not limited to being arranged on the second side of the handpiece 300. For example, specifically, the limiting structure includes a third limiting portion and a fourth limiting portion arranged on the first rotating shaft portion 530, and a third stop portion and a fourth stop portion arranged on the first supporting member 510. The third limiting portion matches with the third stop portion to limit the handpiece 300 from continuing to rotate when it rotates along the first rotation direction to the first limit rotation position; the fourth limiting portion matches with the fourth stop portion to limit the handpiece 300 from continuing to rotate when it rotates along the second rotation direction to the second limit rotation position.

[0144] Similarly, it is feasible to simultaneously set the limiting structures on both sides of the handpiece 300. It is understandable that the specific structure of the limiting structure located on the first side of the handpiece 300 and the specific structure of the limiting structure located on the second side of the handpiece 300 may be the same or different, but what needs to be satisfied is that the two limit rotation positions of the handpiece 300 defined by the two limiting structures are the same.

[0145] In one embodiment, see Fig.14 The first limiting portion 610 is also provided with a first magnetic member, the second limiting portion 620 is provided with a second magnetic member, the first stop portion 630 is provided with a first induction member 631, and the second stop portion 640 is provided with a second induction member 641. The first induction member 631 can sense the first magnetic member, and the second induction member 641 can sense the second magnetic member. The first induction member 631 and the second induction member 641 are respectively connected to the main control board. As mentioned above, the first limiting portion 610 and the second limiting portion 620 can be the ends of the limiting block along the circumferential direction, respectively, and the first stop portion 630 and the second stop portion 640 can be the ends of the stopping block at both ends, respectively, that is, the first magnetic member and the second magnetic member can be arranged at the ends of the limiting block along the circumferential direction, and the first induction member 631 and the second induction member 641 can be arranged at the ends of the stopping block at both ends.

[0146] When the head 300 rotates to the first extreme rotation position along the first rotation direction, the first sensing component 631 can sense the first magnetic component and output a corresponding sensing signal; when the head 300 rotates to the second extreme rotation position along the second rotation direction, the second sensing component 641 can sense the second magnetic component and output a corresponding sensing signal.

[0147] The first sensing element 631 and the second sensing element 641 are electrically connected to the main control board respectively. The main control board can obtain sensing signals of the first sensing element 631 and the second sensing element 641 and further determine the position of the head 300 according to the sensing signals.

[0148] In one embodiment, the first sensing element 631 and / or the first sensing element 631 is a Hall sensor, and the first magnetic element and / or the second magnetic element is a magnet.

[0149] In one embodiment, see Fig.15 The cooking device further includes a first identification mechanism, which is disposed on the base 110 and is used to detect whether the first pot body 210 is placed on the base 110. The first identification mechanism can be electrically connected to the main control board, and the main control board can determine whether the first pot body 210 is placed on the base 110 according to the identification signal output by the first identification mechanism, and then execute the corresponding control process.

[0150] Specifically, see Fig.15 The base 110 has a first placement surface 111, and the first identification mechanism includes a first trigger 120 and a first micro switch 130. The first micro switch 130 is electrically connected to the main control board. The first trigger 120 is convexly arranged on the first placement surface 111 and can be movably switched between a natural state and a triggered state; when the first pot body 210 is placed on the base 110, the first trigger 120 switches from a natural state to a triggered state to drive the first micro switch 130 to close; when the first pot body 210 leaves the base 110, the first trigger 120 switches from a triggered state to a natural state to drive the first micro switch 130 to open. The main control board can detect the switch state of the first micro switch 130, and determine whether the first pot body 210 is placed on the base 110 according to the detection result.

[0151] Furthermore, the first identification mechanism further includes a linkage component 140. One end of the linkage component 140 is connected to the first trigger, and the other end is connected to the first micro switch 130. The first trigger drives the first micro switch 130 to operate through the linkage component 140. In other words, when the first trigger moves to the trigger state, the linkage component 140 is driven to move, and the linkage component 140 moves to trigger the first micro switch 130. When the first trigger moves to the natural state, the linkage component 140 is driven to move, and the linkage component 140 moves to stop triggering the first micro switch 130, and the first micro switch 130 is disconnected.

[0152] Optionally, in another feasible implementation manner, the first identification mechanism is not limited thereto, and may also be an infrared sensor or an image sensor, etc.

[0153] In one embodiment, see Fig.16 The cooking device further includes a second identification mechanism, which is disposed at the heating opening 310 of the machine head 300 and is used to detect whether the first pot body 210 or the second pot body 220 is placed on the top side of the machine head 300. The second identification mechanism can be electrically connected to the main control board, and the main control board can determine whether the second pot body 220 or the first pot body 210 is placed at the heating opening 310 of the machine head 300 according to the identification signal output by the second pot identification mechanism, and then execute the corresponding control process.

[0154] Specifically, see Fig.16 The heating opening 310 has a second placement surface 320, and the second identification mechanism includes a second trigger member 330 and a second micro switch. The second micro switch is electrically connected to the main control board, and the second trigger member 330 is convexly arranged on the second placement surface 320 and can be movably switched between a natural state and a triggered state. When the second pot body 220 or the first pot body 210 is placed on the top side of the machine head 300, the second trigger member 330 switches from a natural state to a triggered state to drive the second micro switch to close; when the second pot body 220 or the first pot body 210 leaves the top side of the machine head 300, the second trigger member 330 switches from a triggered state to a natural state to drive the second micro switch to open. The main control board can determine whether the first pot body 210 or the second pot body 220 is placed on the top side of the machine head 300 according to the detected switch state of the second micro switch.

[0155] The second trigger member 330 may be a trigger rod protruding from the second placement surface 320. When the second pot body 220 or the first pot body 210 is placed on the second placement surface 320, the trigger rod will shrink downward, thereby triggering the second micro switch to close. When the second pot body 220 or the first pot body 210 leaves the second placement surface 320, the trigger rod will protrude upward, and the second micro switch will be disconnected. The main control board can determine whether the second pot body 220 or the first pot body 210 is placed on the top side of the machine head 300 by detecting the state of the second micro switch.

[0156] The weight of the head 300 is about 1200g-2800g. The main body 100, the head 300 and the first pot body 210 constitute a first complete machine, and the weight ratio of the head 300 to the first complete machine is 0.2-0.5. The main body 100, the head 300 and the second pot body 220 constitute a second complete machine, and the weight ratio of the first complete machine to the second complete machine is 0.8-2.

[0157] In one embodiment, a weight detection structure is provided on the side of the base 110 facing away from the machine head 300, and the weight detection structure is electrically connected to the main control board. The weight detection structure can detect the overall weight of the cooking device, and then determine whether the rotary drive mechanism 400 can operate according to the overall weight. For example, the preset weight values ​​of the whole machine without a pot, the whole machine with a frying pan, the whole machine with a frying pan, the whole machine with a frying pan and a grill can be pre-stored in the main control board, and the main control board can compare the overall weight detected by the weight detection structure with each preset weight value, and then determine the current state of the cooking device to determine whether the rotary drive mechanism 400 can operate.

[0158] In another embodiment, a control method of a cooking device is also provided, wherein the cooking device includes a main body 100, a first pot body 210 and / or a second pot body 220, a head 300 and a rotary drive mechanism 400, the main body 100 includes a base 110, the first pot body 210 can be placed on the base 110, the head 300 can be rotatably arranged on the main body 100 to switch between a first working position and a second working position, the head 300 is provided with a heating opening 310, when the head 300 is located at the first working position, the heating opening 310 faces the base 110 to dock with the opening of the first pot body 210, when the head 300 is located at the second working position, the heating opening 310 faces away from the base 110, and the rotary drive mechanism 400 is connected to the head 300 or the main body 100, and is used to drive the head 300 to switch between the first working position and the second working position. For the specific structure of the cooking device, please refer to the specific description of the cooking device provided in the above embodiment, which will not be repeated here.

[0159] See also Fig.17 , the control method provided in this embodiment includes:

[0160] Step S100, determining the initial position of the head 300;

[0161] Step S300: when the initial position of the machine head 300 is the first working position, determine whether the first pot body 210 is placed on the base 110;

[0162] Step S500: If the first pot body 210 is not placed on the base 110, a control signal is sent to the rotation drive mechanism 400 after receiving the rotation command input by the user, so that the rotation drive mechanism 400 drives the head 300 to rotate around the rotation axis and switches the head 300 to the second working position.

[0163] After starting the cooking device, the initial position of the machine head 300 can be determined first, and then combined with the initial position of the machine head 300, it can be determined whether the rotation drive mechanism 400 can be started. Specifically, when the initial position of the machine head 300 is the first working position, that is, the cooking device is in the air frying mode, it is further determined whether the first pot body 210 is placed on the base 110. If it is not placed on the base 110, it means that the machine head can be rotated at this time. The user can input a rotation instruction through the operation panel. The main control board responds to the rotation instruction input by the user, and then sends a control signal to the rotation drive mechanism 400, thereby controlling the rotation drive mechanism 400 to drive the machine head 300 to rotate around the rotation axis to switch the machine head 300 to the second working position. In this way, the machine head 300 can be automatically adjusted to the correct working position, thereby switching the cooking device to the appropriate working mode.

[0164] In one embodiment, the main body 100 includes a supporting mechanism, which is connected to the base 110. The supporting mechanism includes a first supporting member 510 and a second supporting member 520 arranged on opposite sides of the base 110. The head 300 is arranged between the first supporting member 510 and the second supporting member 520 via a rotating shaft, and the rotating shaft is rotatably connected to the first supporting member 510 and the second supporting member 520; the cooking device also includes a limiting structure 600, which includes a first limiting portion 610 and a second limiting portion 620 arranged on the rotating shaft and a first stopping portion 630 and a second stopping portion 640 arranged on the supporting mechanism, the first limiting portion 610 matches the first stopping portion 630, the second limiting portion 620 matches the second stopping portion 640, the first limiting portion 610 is provided with a first magnetic member, the first stopping portion 630 is provided with a first sensing member 631, the second limiting portion 620 is provided with a second magnetic member, and the second stopping portion 640 is provided with a second sensing member 641;

[0165] See also Fig.18 Step S100, i.e., the step of determining the initial position of the head 300, comprises:

[0166] Step S110, obtaining the sensing result of the first sensing element 631 on the first magnetic element and the sensing result of the second sensing element 641 on the second magnetic element;

[0167] Step S130: Determine the initial position of the head 300 according to the sensing result.

[0168] When the handpiece 300 is at different positions, the distance between the sensing element and the corresponding magnetic element is different, so the sensing result of the sensing element on the magnetic element is different. Therefore, the position of the handpiece can be determined according to the sensing result of the sensing element on the magnetic element.

[0169] Specifically, when the first sensing component senses the signal of the first magnetic component, the initial position of the machine head is determined to be the first working position, i.e., the empty frying position; when the second sensing component senses the signal of the second magnetic component, the initial position of the machine head is determined to be the second working position, i.e., the frying or steaming mode; when the first sensing component does not sense the signal of the first magnetic component and the second sensing component does not sense the signal of the second magnetic component, it is determined that the machine head is not in the first working position and is not in the second working position.

[0170] When it is determined that the machine head is not in the first working position and not in the second working position, the user can input a rotation command through the operation panel, and the main control board can send a control signal to the rotation drive mechanism after receiving the rotation command input by the user, so that the rotation drive mechanism drives the machine head to rotate around the rotation axis and rotates the machine head to the first working position or the second working position.

[0171] In one embodiment, the cooking device further includes a first identification mechanism, and the first identification mechanism is disposed on the base 110 .

[0172] See also Fig.19 Step S300, i.e., the step of determining whether the first pot body 210 is placed on the base 110, includes:

[0173] Step S310: Obtain an identification signal from a first identification mechanism.

[0174] Specifically, the base 110 has a first placement surface 111, and the first identification mechanism includes a first trigger 120 and a first micro switch 130. The first trigger 120 is convexly arranged on the first placement surface 111 and can be movably switched between a natural state and a triggered state. When the first pot body 210 is placed on the base 110, the first trigger 120 switches from a natural state to a triggered state to drive the first micro switch 130 to close; when the first pot body 210 leaves the base 110, the first trigger 120 switches from a triggered state to a natural state to drive the first micro switch 130 to open.

[0175] In step S310 , a switch signal of the first micro switch 130 may be acquired.

[0176] Step S330 : determining whether the first pot body 210 is placed on the base 110 according to the recognition signal of the first recognition mechanism.

[0177] Whether the first pot 210 is placed on the base 110 can be determined according to the switch signal of the first micro switch 130. For example, when the switch signal of the first micro switch 130 is a closed signal, it can be determined that the first pot 210 is placed on the base 110; when the switch signal of the first micro switch 130 is an open signal, it can be determined that the first pot 210 is not placed on the base 110.

[0178] When the initial position of the machine head is the first working position, and it is determined that the first pot body is placed on the base, the user can perform menu operations of the first working mode through the operation panel.

[0179] See also Fig. 20 The control method of the cooking device provided in this embodiment also includes:

[0180] Step S400: when the initial position of the machine head 300 is the second working position, determine whether the second pot body 220 or the first pot body 210 is placed on the top side of the machine head 300;

[0181] Step S600: If the second pot body 220 or the first pot body 210 is not placed on the top side of the machine head 300, a control signal is sent to the rotation drive mechanism 400 after receiving the rotation command input by the user, so that the rotation drive mechanism 400 drives the machine head 300 to rotate around the rotation axis and switches the machine head 300 to the first working position.

[0182] When the initial position of the machine head 300 is the second working position, that is, the cooking device is in the frying and steaming mode, it is further determined whether the second pot body 220 or the first pot body 210 is placed on the top side of the machine head 300, that is, at the heating opening 310. If it is not placed on the top side of the machine head 300, the user can input a rotation instruction through the operation panel at this time. When the main control board receives the rotation instruction input by the user, it can control the rotation drive mechanism 400 to drive the machine head 300 to rotate around the rotation axis to switch the machine head 300 to the first working position. In this way, the machine head 300 can be automatically adjusted to the correct working position, and then the cooking device can be switched to the appropriate working mode.

[0183] In one embodiment, the cooking device further includes a second identification mechanism, which is disposed at the heating opening 310 of the machine head 300 .

[0184] See also Fig.21 Step S400, i.e., the step of determining whether the second pot body 220 or the first pot body 210 is placed on the top side of the machine head 300, includes:

[0185] Step S410: Obtain an identification signal from a second identification mechanism.

[0186] Specifically, the heating opening 310 has a second placement surface 320, and the second identification mechanism includes a second trigger member 330 and a second micro switch. The second trigger member 330 is convexly arranged on the second placement surface 320 and can be movably switched between a natural state and a triggered state; when the second pot body 220 or the first pot body 210 is placed on the top side of the handpiece 300, the second trigger member 330 switches from the natural state to the triggered state to drive the second micro switch to close; when the second pot body 220 or the first pot body 210 leaves the top side of the handpiece 300, the second trigger member 330 switches from the triggered state to the natural state to drive the second micro switch to open;

[0187] In step S410, a switch signal of the second micro switch may be acquired.

[0188] Step S430 : determining whether the second pot body 220 or the first pot body 210 is placed on the top side of the machine head 300 according to the recognition signal of the second recognition mechanism.

[0189] According to the switch signal of the second micro switch, it can be determined whether the second pot 220 or the first pot 210 is placed on the top side of the handpiece 300. For example, when the switch signal of the second micro switch is a closed signal, it can be determined that the second pot 220 or the first pot 210 is placed on the top side of the handpiece 300; when the switch signal of the second micro switch is an open signal, it can be determined that the second pot 220 or the first pot 210 is not placed on the top side of the handpiece 300.

[0190] When the initial position of the machine head is the second working position, and it is determined that the first pot body or the second pot body is placed on the base, the user can perform menu operations of the second working mode through the operation panel.

[0191] In one embodiment, in step S500, i.e., the step of causing the rotary drive mechanism 400 to drive the machine head 300 to rotate around the rotation axis and switching the machine head 300 to the second working position, the sensing signal of the first sensing element 631 is obtained, and if the first sensing element 631 senses the first magnetic element, the rotary drive mechanism 400 is controlled to stop running.

[0192] In step S600, i.e., the step of making the rotary drive mechanism 400 drive the machine head 300 to rotate around the rotation axis and switching the machine head 300 to the first working position, the sensing signal of the second sensing element 641 is obtained. If the second sensing element 641 senses the second magnetic element, the rotary drive mechanism 400 is controlled to stop running.

[0193] That is, when the rotary drive mechanism 400 drives the machine head 300 to rotate, it can determine whether the limit position has been reached based on the inductive signals of the first sensing element 631 and / or the second sensing element 641. When the limit position is reached, the rotary mechanism is promptly controlled to stop running to avoid over-rotation.

[0194] In one embodiment, step S500 may include: obtaining the required rotation angle of the handpiece 300 and controlling the rotation drive mechanism 400 to drive the handpiece 300 to rotate around the rotation axis by a corresponding angle, so as to switch the handpiece 300 to the second working position.

[0195] Likewise, step S600 may include: acquiring the required rotation angle of the handpiece 300 and controlling the rotation drive mechanism 400 to drive the handpiece 300 to rotate around the rotation axis by a corresponding angle, so as to switch the handpiece 300 to the first working position.

[0196] That is to say, in addition to the aforementioned method of realizing the rotation of the head 300 by combining with the limiting structure, the rotation drive mechanism 400 can also be controlled to drive the head 300 to rotate to the corresponding angle by determining the angle at which the head 300 needs to rotate, so as to switch the head 300 to the corresponding working position.

[0197] In one embodiment, a weight detection structure is provided on the side of the base facing away from the machine head, that is, the weight detection structure can detect the overall weight of the cooking device. The weight detection structure includes but is not limited to a weight sensor. The control method of the cooking device provided in this embodiment also includes: obtaining a weight value detected by the weight detection structure; when the weight value is within a first range, determining that the cooking device is in a first working mode; when the weight value is within a second range, determining that the cooking device is in a second working mode; when the weight value is within a third range, determining that no pot is placed in the cooking device.

However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
