The water tank is revealed by extending and rotating the control panel, facilitating easy disassembly.

[0003] The existing drive panel movement structure is complex, not only taking up a lot of space, but also having poor stability, which affects the user experience. Utility Model Content

[0004] The purpose of this invention is to provide a panel driving device and a cooking appliance that can solve the problems of complex structure, large space occupation, and poor stability in driving panel movement.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0007] A track support, wherein a first guide groove extending along a first horizontal direction is provided on the track support;

[0008] A panel bracket is provided with a guide shaft, which is slidably engaged with the first guide groove and can rotate within the first guide groove. One end of the panel bracket is used to hinge a panel assembly.

[0009] A drive mechanism, the output end of which can reciprocate along the first horizontal direction, is movably connected to the other end of the panel bracket to drive the panel bracket to reciprocate and rotate along the first horizontal direction.

[0010] As an optional solution for the aforementioned panel driving device, a sliding groove is provided at the other end of the panel bracket, and a limiting shaft is provided on the output end. The limiting shaft slides in cooperation with the sliding groove, and the extension direction of the sliding groove is set at an angle to the horizontal plane.

[0011] As an alternative to the aforementioned panel driving device, the panel support includes a first support rod and a second support rod that are angled together and connected. The bottom end of the first support rod is movably connected to the output end, and the bottom end of the second support rod is hinged to the panel assembly.

[0012] As an alternative to the aforementioned panel driving device, the guide shaft is disposed at the connection between the first support rod and the second support rod, wherein the length of the second support rod is greater than the length of the first support rod.

[0013] As an optional solution for the above-mentioned panel driving device, the track bracket is provided with a second guide groove extending along the first horizontal direction, and the length of the second guide groove is greater than the length of the first guide groove.

[0014] A slider is provided on the output end, and the slider is slidably engaged with the second guide groove. When the guide shaft is located at one end of the first guide groove near the panel assembly, the slider and the two ends of the second guide groove are spaced apart.

[0015] As an alternative to the above-mentioned panel driving device, the output end is provided with at least two mounting portions arranged along the first horizontal direction, and the mounting portions are used to detachably connect the sliding member;

[0016] And / or, the track support is provided with at least two second guide grooves, and each second guide groove is correspondingly provided with the sliding member.

[0017] As an optional solution to the above-mentioned panel driving device, the panel driving device further includes a detection component, which includes a first sensor and a second sensor disposed on the track bracket. The first sensor is triggered when the slider is located at the end of the second guide groove near the panel assembly, and the second sensor is triggered when the slider is located at the end of the second guide groove away from the panel assembly. Both the first sensor and the second sensor are electrically connected to the driving mechanism.

[0018] As an alternative to the aforementioned panel driving device, the track bracket includes two bracket plates that are opposite to each other and spaced apart along a second horizontal direction. At least a portion of the panel bracket is located between the two bracket plates. Each bracket plate is provided with the first guide groove, and the guide shaft is provided on both sides of the panel bracket. The second horizontal direction is perpendicular to the first horizontal direction.

[0019] As an optional solution to the above-mentioned panel driving device, the panel driving device further includes a detection component. The detection component includes a first sensor and a second sensor disposed on the track bracket. The guide shaft includes a shaft body and a trigger part protruding radially along the shaft body. When the trigger part is located at one end of the first guide groove near the panel assembly, it can rotate with the shaft body to a preset position and trigger the first sensor. When the trigger part is located at one end of the first guide groove away from the panel assembly, it triggers the second sensor. Both the first sensor and the second sensor are electrically connected to the driving mechanism.

[0020] Alternatively, the detection component includes a stall sensor, which is used to detect whether the drive mechanism is stalled, and the stall sensor is electrically connected to the drive mechanism.

[0021] A cooking appliance includes a body, a panel assembly, and the aforementioned panel driving device, wherein the track support is disposed on the body and the panel support is hinged to the panel assembly.

[0022] The beneficial effects of this utility model are:

[0023] In the panel driving device provided by this utility model, when the panel driving device is in its initial state and the output end of the driving mechanism moves forward, the output end applies a pushing force to the panel bracket. At this time, the guide shaft is located at the rear end of the first guide groove, and the gravity of the panel assembly acts on the front end of the panel bracket, making the sliding resistance of the panel bracket sliding forward much smaller than the rotational resistance of the panel bracket. Therefore, the panel bracket will move forward under the action of the driving mechanism, realizing the panel assembly extending forward. When the guide shaft moves to the front end of the first guide groove, the sliding resistance of the panel bracket increases due to the obstruction of the first guide groove, and is greater than the rotational resistance of the panel bracket. When the output end of the driving mechanism continues to move forward, the panel bracket will rotate relative to the track bracket around the guide shaft to realize the lifting and lowering of the panel assembly.

[0024] The linear motion output by the drive mechanism, combined with the guiding effect of the guide shaft and the first guide groove, can realize both the reciprocating linear movement of the panel bracket and the rotation of the panel bracket. The panel bracket does not move back and forth during the rotation, reducing the space and size occupied by the drive mechanism, which is beneficial to reducing the extension distance of the panel assembly and improving the stability of the panel assembly. The first guide groove extends in a straight line, with a simple structure and convenient processing.

[0025] The cooking appliance provided by this utility model adopts the above-mentioned panel driving device, which has a simple structure and is conducive to shortening the distance of the panel assembly moving in the front and back direction, thereby shortening the length of the overall structure and avoiding interference between the panel assembly and the cabinet.

[0042] Example 1

[0043] This embodiment provides a cooking appliance, including a body, a control panel assembly, and a cooking component, the cooking component including a water tank. A cooking cavity is formed within the body; the water tank is mounted on the body and is used to hold water. The cooking component communicates with the cooking cavity to supply water to the cavity, using the water to cook the food and improve its texture. The control panel assembly is electrically connected to a steam-grill assembly, used for user interaction and to control the start / stop of the steam-grill assembly and adjust its operating parameters.

[0044] In this embodiment, the cooking component can be a steam-grill component, enabling the cooking appliance to have steam-grilling functions. It should be noted that steam-grill components are a conventional structure in the art, and this embodiment can employ the principles and structures of any existing steam-grill component; specific details will not be provided here.

[0045] To avoid the water tank occupying space within the cooking cavity, the water tank is located at the top of the unit, with the control panel positioned in front of it. This arrangement allows for a larger control panel to accommodate the trend towards smarter home appliances. It also utilizes the space behind the control panel to house the water tank, preventing any impact on the size of the cooking cavity. Furthermore, the control panel can conceal the water tank from the front. Since cooking appliances are typically embedded in kitchen cabinets, with only the front of the appliance exposed, the water tank remains hidden by the control panel, improving the overall aesthetics and enhancing the product's appearance.

[0046] To facilitate the replenishment of water into the water tank, the cooking appliance also includes a panel drive device. The panel drive device is located on the top of the appliance and is connected to the panel assembly. It can drive the panel assembly to extend forward and then flip up to expose the water tank, making it easy to remove and place the water tank for replenishment. It can also drive the panel assembly to return to its original position and cover the water tank.

[0047] like Figure 1 As shown, the panel driving device includes a track bracket 10, a driving mechanism 30, and a panel bracket 20. The track bracket 10 is located on the top of the machine body. One end of the panel bracket 20 is hinged to the panel assembly 100, and the panel bracket 20 is movably connected to the track bracket 10. The other end of the panel bracket 20 is movably connected to the output end of the driving mechanism 30. The track bracket 10 guides the panel bracket 20, allowing the panel bracket 20 to slide back and forth relative to the track bracket 10 in a first horizontal direction, thereby driving the panel assembly 100 to extend and retract in the first horizontal direction. When the panel bracket 20 slides to a designated position closer to the panel assembly 100 in the first horizontal direction, the panel bracket 20 can rotate relative to the track bracket 10, thereby driving the panel assembly 100 to rise and fall. This design allows the panel assembly 100 to extend forward via the linear movement of the panel bracket 20, which is compatible with the thickness and installation requirements of the panel assembly 100, avoids collisions and interference between the panel assembly 100 and the cabinet, and solves the problem of the panel assembly 100 being too thick to be easily flipped. The rotation of the panel bracket 20 can raise and lower the panel assembly 100 so that the water tank is exposed, making it convenient to put the water tank in and out.

[0048] In this embodiment, the first horizontal direction is the front-to-back direction. It should be noted that the front-to-back direction specifically refers to the side of the panel assembly 100 with the interactive surface as the front side, that is, the front side of the panel assembly 100 faces the user, and the side of the panel assembly 100 away from the interactive surface is the rear side. The panel assembly 100 extending means that the panel assembly 100 moves forward under the drive of the panel driving device to extend out of the cabinet body in which the cooking appliance is embedded.

[0049] Combination Figure 1 and Figure 2 As shown, the track support 10 is provided with a first guide groove 111, which extends along a first horizontal direction, that is, the first guide groove 111 extends along the front-back direction; the panel support 20 includes a support body 21 and a guide shaft 22 disposed on the support body 21. The guide shaft 22 is slidably engaged with the first guide groove 111 and can rotate within the first guide groove 111 to guide the movement of the panel support 20, thereby constraining the movement trajectory of the panel support 20; the output end of the drive mechanism 30 can reciprocate along the first horizontal direction to drive the panel support 20 to reciprocate and rotate along the first horizontal direction.

[0050] For ease of explanation, the panel drive device is defined as follows: when the output end of the drive mechanism 30 moves backward to its limit position, the panel drive device is in its initial state, at which time the panel assembly 100 is blocked on the front side of the water tank; when the output end of the drive mechanism 30 moves forward and drives the panel support 20 to extend forward to its maximum distance, the panel drive device is in its extended state, at which time the panel assembly 100 moves forward to its maximum distance, and the guide shaft 22 is located in the first guide groove 111; when the output end of the drive mechanism 30 moves forward to its limit position, the panel drive device is in its flipped state, at which time the panel support 20 rotates to its maximum angle.

[0051] In this embodiment, the other end of the panel support 20 is movably connected to the output end of the drive mechanism 30. When the panel drive device is in the initial state and the output end of the drive mechanism 30 moves forward, the output end applies a pushing force to the panel support 20. At this time, the guide shaft 22 is located at the rear end of the first guide groove 111, and the gravity of the panel assembly 100 acts on the front end of the panel support 20, making the sliding resistance of the panel support 20 sliding forward much smaller than the rotational resistance of the panel support 20 rotating. Therefore, the panel support 20 will move forward under the action of the drive mechanism 30, realizing the panel assembly 100 extending forward. When the guide shaft 22 moves to the front end of the first guide groove 111, the sliding resistance of the panel support 20 increases due to the obstruction of the first guide groove 111, and is greater than the rotational resistance of the panel support 20. When the output end of the drive mechanism 30 continues to move forward, the panel support 20 will rotate relative to the track support 10 around the guide shaft 22 to realize the lifting and lowering of the panel assembly 100.

[0052] In this embodiment, the linear motion output by the drive mechanism 30, combined with the guiding effect of the guide shaft 22 and the first guide groove 111, can realize both the reciprocating linear movement of the panel support 20 and the rotation of the panel support 20. The panel support 20 does not move back and forth during the rotation, reducing the space and size occupied by the drive mechanism 30, which is beneficial to reducing the extension distance of the panel assembly 100 and improving the stability of the panel assembly 100. The first guide groove 111 extends in a straight line, has a simple structure, and is easy to process.

[0053] like Figure 2 As shown, in this embodiment, the other end of the panel bracket 20 is slidably connected to the output end of the drive mechanism 30. Specifically, the output end of the drive mechanism 30 is provided with a limiting shaft 313, and the other end of the panel bracket 20 is provided with a sliding groove 2111. The extension direction of the sliding groove 2111 is set at an angle to the horizontal plane. The limiting shaft 313 is located in the sliding groove 2111 and can slide and rotate within the sliding groove 2111. Through the cooperation of the limiting shaft 313 and the sliding groove 2111, the driving force can be transmitted through the contact between the limiting shaft 313 and the inner wall of the sliding groove 2111 to drive the panel bracket 20 to move linearly and rotate. The sliding groove 2111 is inclined in the front-back direction, which can provide movement space for the rear end of the bracket body 21 to move around the guide shaft 22. During the rotation of the bracket body 21 around the guide shaft 22, the relative position of the limiting shaft 313 in the sliding groove 2111 will be adaptively adjusted to avoid structural interference and ensure the smooth lifting and lowering of the panel assembly 100.

[0054] Understandably, the slide rail 2111 determines the lifting height of the panel assembly 100. By setting the specific dimensions of the slide rail 2111, the angular range of rotation of the bracket body 21 around the guide shaft 22 can be limited, thereby controlling the lifting height of the control panel assembly 100.

[0055] Optionally, the slide 2111 can be an inclined straight groove or an arc groove, as long as it can provide clearance space for the limit shaft 313 when the bracket body 21 rotates.

[0056] In order to increase the lifting height of the panel assembly 100 while keeping the extension distance of the panel assembly 100 unchanged, such as Figure 2As shown, the bracket body 21 includes a first bracket rod 211 and a second bracket rod 212 connected at an angle. The bottom end of the first bracket rod 211 is connected to the output end of the drive mechanism 30, and the bottom end of the second bracket rod 212 is hinged to the panel assembly 100. That is, the top ends of the first bracket rod 211 and the second bracket rod 212 are connected, and the opening of the angle formed by the first bracket rod 211 and the second bracket rod 212 faces downward. This arrangement allows the front and rear ends of the bracket body 21 to be low, facilitating the connection between the panel bracket 20 and the bottom end of the panel assembly 100. When the panel drive device is in its initial state, the bottom end of the panel assembly 100 is approximately at the same height as the output end of the drive mechanism 30, resulting in a low center of gravity for the panel assembly 100. This provides good support for the panel assembly 100 from the panel bracket 20, making the structure more stable.

[0057] Furthermore, compared to a straight-extending support body, the panel support 20 has a larger rotation angle and a larger lifting distance of the panel assembly 100 by means of the first support rod 211 and the second support rod 212 arranged at an angle, while the moving distance of the output end of the drive mechanism 30 remains unchanged. This is beneficial to reduce the moving space required by the drive mechanism 30. The angled space formed by the first support rod 211 and the second support rod 212 can avoid interference between the support body 21 and other structures.

[0058] In this embodiment, the first support rod 211 and the second support rod 212 can be arranged vertically. In other embodiments, the first support rod 211 and the second support rod 212 can be arranged at an acute angle or an obtuse angle.

[0059] Optionally, the slide 2111 may extend along the length of the first support rod 211.

[0060] In this embodiment, the guide shaft 22 is located at the connection position of the first support rod 211 and the second support rod 212, so that when the drive mechanism 30 applies a thrust to the bottom end of the first support rod 211, the torque of the thrust is approximately equal to the length of the first support rod 211, which is beneficial to increase the rotation angle of the first support rod 211 when the output end of the drive mechanism 30 moves a unit distance.

[0061] Optionally, the length of the second support rod 212 is greater than the length of the first support rod 211. By increasing the length of the second support rod 212, the radius of rotation of the panel assembly 100 around the guide shaft 22 during lifting can be increased, thereby increasing the lifting height of the panel assembly 100 when the second support rod 212 rotates by a unit angle.

[0062] In this embodiment, the drive mechanism 30 includes a rack 31, which serves as the output end of the drive mechanism 30 and can reciprocate along the first horizontal direction. The front end of the rack 31 is connected to the panel bracket 20, which helps to shorten the length of the rack 31 and reduce the space occupied by the drive mechanism 30.

[0063] In other embodiments, the drive mechanism 30 can be a structure capable of outputting linear motion, such as an electric actuator, a lead screw and nut drive mechanism, a cylinder, or a hydraulic cylinder.

[0064] like Figure 3 As shown, when the panel drive device is in the initial state, the panel bracket 20 is positioned rearward, the rack 31 is located at the rear limit position, and the guide shaft 22 is located at the rear end of the first guide groove 111.

[0065] like Figure 4 As shown, when the rack 31 moves forward, the limiting shaft 313 at the front end of the rack 31 abuts against the inner wall of the sliding groove 2111 on the first support rod 211, thereby applying a pushing force to the panel support 20. Since the guide shaft 22 slides into the first guide groove 111, and the panel support 20 is subjected to the downward gravity of the panel assembly 100, the sliding resistance experienced by the panel support 20 as it slides forward is much less than the rotational resistance experienced when the panel support 20 rotates. Therefore, the panel support 20 will move along the first horizontal direction without rotating, thus enabling the extension and retraction of the panel assembly 100.

[0066] As the rack 31 moves forward, the guide shaft 22 moves to the front end of the first guide groove 111. The guide shaft 22 abuts against the inner wall of the front end of the first guide groove 111, restricting the panel bracket 20 from moving forward. The panel drive device is in the extended state. At this time, the panel assembly 100 extends forward to the maximum distance.

[0067] like Figure 5 As shown, when the rack 31 continues to move forward, the panel bracket 20 is restricted from continuing to move linearly due to the contact between the guide shaft 22 and the first guide groove 111. At this time, the sliding resistance experienced by the panel bracket 20 is greater than the rotational resistance experienced by the panel bracket 20. Driven by the rack 31, the panel bracket 20 will rotate around the axis of the guide shaft 22, thereby driving the panel assembly 100 to move and avoid the front position of the water tank, thus facilitating the removal and placement of the water tank. During this process, the guide shaft 22 rotates within the end of the first guide groove 111 closest to the panel assembly 100 (i.e., the front end) to avoid interfering with the rotation of the panel bracket 20.

[0068] In this embodiment, after the panel bracket 20 moves forward to the designated position, it rotates upward with the cooperation of the rack 31, the guide shaft 22, and the first guide groove 111, thereby lifting the panel assembly 100. This arrangement ensures that the interactive surface of the panel assembly 100 always faces forward, i.e., towards the user, during the lifting process, which facilitates user operation and improves the appearance.

[0069] Understandably, when the water tank is assembled and the panel drive device needs to switch from the flipped state to the initial state, the rack 31 moves backward in the opposite direction. At this time, the weight of the panel assembly 100 is the assist force for the rotation of the panel support 20. The panel support 20 will first rotate in the opposite direction, causing the panel assembly 100 to fall back, so that the panel drive device moves to the extended state. At this time, the weight of the panel assembly 100 is converted into the resistance to the continued rotation of the panel support 20. The rotational resistance of the panel support 20 is greater than the sliding resistance. When the rack 31 continues to move backward, it will drive the panel support 20 to move backward synchronously until it returns to the initial state.

[0070] It is understandable that the first guide groove 111 can not only provide guidance for the linear movement of the panel bracket 20 by cooperating with the guide shaft 22, but also limit the forward extension distance of the panel bracket 20. In other words, the length of the first guide groove 111 is the extension distance of the panel assembly 100. By reasonably setting the length of the first guide groove 111, the extension distance of the panel assembly 100 can be designed to meet the needs of different models and installation environments.

[0071] Optionally, the first guide groove 111 can be an oblong groove, and the sidewalls at both ends of the first guide groove 111 along the first horizontal direction are arc surfaces, so that when the guide shaft 22 moves to both ends of the first guide groove 111, it can rotate and cooperate with the arc surfaces, thereby improving the stability of the guide shaft 22.

[0072] In this embodiment, combined with Figures 2-3 As shown, the track support 10 is also provided with a second guide groove 112 extending along the first horizontal direction. The length of the second guide groove 112 is greater than the length of the first guide groove 111. A slider 311 is provided on the rack 31, and the slider 311 is slidably engaged with the second guide groove 112. When the guide shaft 22 is located at the end of the first guide groove 111 near the panel assembly 100, the two ends of the slider 311 and the second guide groove 112 are spaced apart. By setting the second guide groove 112 to engage with the slider 311, the sliding of the rack 31 can be further guided, which is beneficial to improving the motion accuracy of the panel support 20. The length of the second guide groove 112 is greater than that of the first guide groove 111. When the guide shaft 22 is at the front end of the first guide groove 111, there is still a distance between the slider 311 and the front end of the second guide groove 112. This distance provides clearance for the rotation of the guide shaft 22 within the first guide groove 111, allowing the panel support 20 to rotate smoothly.

[0073] It is understandable that, such as Figure 4As shown, when the guide shaft 22 is located at the end of the first guide groove 111 near the panel assembly 100 (i.e., the front end), the distance between the slider 311 and the end of the second guide groove 112 near the panel assembly 100 (i.e., the front end) is defined as the first distance. The first distance determines the maximum flip angle of the panel bracket 20. By reasonably designing the first distance, the maximum flip angle of the panel bracket 20 can be adjusted to meet the requirements of the model and installation.

[0074] To facilitate adjustment of the maximum tilt angle of the panel bracket 20, refer to... Figure 2 As shown, the rack 31 is provided with at least two mounting portions 312 arranged along the first horizontal direction. The mounting portions 312 are used to detachably connect to the sliding member 311. By providing at least two mounting portions 312 and detachably connecting the mounting portions 312 to the sliding member 311, the mounting portion 312 connected to the sliding member 311 can be selected according to actual needs, thereby adjusting the first distance and thus adjusting the maximum flip angle of the panel bracket 20.

[0075] In this embodiment, the mounting part 312 can be a mounting hole, and the sliding member 311 can be detachably connected to the mounting hole. Optionally, the mounting hole is a threaded hole to facilitate disassembly and assembly.

[0076] In other embodiments, the mounting part 312 can be a slot, and the sliding member 311 engages with the slot to achieve a detachable connection. For example, one of the inner wall of the slot and the sliding member 311 is provided with a locking hole, and the other is provided with a snap-fit; the snap-fit ​​is secured by the engagement of the snap-fit ​​with the locking hole.

[0077] To improve the stability of the rack 31's movement, at least two second guide grooves 112 can be provided on the track support 10. Each second guide groove 112 is provided with a corresponding sliding member 311 to improve the guiding effect on the rack 31 through multiple sliding engagements, thereby improving the movement accuracy of the rack 31.

[0078] In this embodiment, two second guide grooves 112 are provided, and the two second guide grooves 112 are spaced apart along the first horizontal direction. Each second guide groove 112 is correspondingly provided with a sliding member 311. In other embodiments, the number and arrangement of the second guide grooves 112 can be adjusted according to actual needs.

[0079] Optionally, the lengths of the two second guide grooves 112 can be equal or unequal, but both must be greater than the length of the first guide groove 111. When the lengths of the two second guide grooves 112 are unequal, the longer second guide groove 112 can provide redundant length, which, together with the position-adjustable slider 311, can accommodate assembly errors and dimensional errors, ensuring the rotation angle of the panel bracket 20.

[0080] In this embodiment, the slider 311 is a sliding shaft to reduce the contact area between the slider 311 and the second guide groove 112 and reduce the sliding friction.

[0081] In other embodiments, the shape of the slider 311 can also be selected according to actual needs. For example, the slider 311 can be a rectangular block, as long as it can slide within the second guide groove 112.

[0082] To improve the stability of the panel assembly 100 during movement, two track brackets 10 and two panel brackets 20 are provided. The two panel brackets 20 are spaced apart along the second horizontal direction, and each panel bracket 20 is correspondingly provided with one track bracket 10. The two panel brackets 20 are respectively connected to both ends of the panel assembly 100 to improve the uniformity of force on the panel assembly 100 and the stability during movement. The second horizontal direction is perpendicular to the first horizontal direction.

[0083] For example, when the first horizontal direction is the front-back direction, the second horizontal direction is the left-right direction.

[0084] In this embodiment, the track support 10 includes two support plates 11 that are arranged opposite to each other and spaced apart along the second horizontal direction. Each support plate 11 is provided with a first guide groove 111 and a second guide groove 112. The rack 31 and at least part of the panel support 20 are located between the two support plates 11. The two support plates 11 restrict the movement direction of the rack 31 and the panel support 20, thereby playing a limiting and guiding role. Correspondingly, guide shafts 22 are provided on both opposite sides of the panel support 20 to cooperate with the first guide grooves 111 on the two side support plates 11 respectively.

[0085] To ensure the synchronization of movement at both ends of the panel assembly (100mm), combined with Figure 1 As shown, the drive mechanism 30 also includes a drive member 32, a transmission rod 34, and two other transmission gear sets 33. The two ends of the transmission rod 34 pass through the corresponding side bracket plates 11 and are respectively fixedly connected to the transmission gear sets 33. The output shaft of the drive member 32 is in transmission engagement with the transmission gear sets 33, and the transmission gear sets 33 mesh with the corresponding side rack 31. After the drive member 32 is started, it drives the rack 31 on one side to reciprocate through the transmission gear sets 33. Simultaneously, the transmission gear set 33 on that side drives the transmission gear set 33 on the other side to move through the transmission rod 34, thereby driving the rack 31 on the other side to reciprocate.

[0086] It should be noted that the transmission gear set 33 can adjust the output speed of the drive component 32 to a suitable speed so that the panel assembly 100 can extend, retract, and rise and fall at a suitable speed. On the other hand, it can prevent the output shaft of the drive component 32 from being collinear with the axis of the transmission rod 34, so that the drive component 32 and the transmission rod 34 can be arranged in the vertical direction to make reasonable use of space.

[0087] Optionally, the drive unit 32 is a rotary motor, and the output shaft of the rotary motor is connected to the transmission gear set 33; the transmission gear set 33 includes at least two meshing transmission gears.

[0088] Optionally, the panel driving device also includes a base plate 50, and the track bracket 10 and the drive mechanism 30 can be mounted on the base plate 50 to form a modular structure for easy assembly and disassembly of the panel driving device.

[0089] To improve the motion accuracy of the panel support 20, the panel drive device also includes a detection component 40. The detection component 40 is used to detect the motion state of the panel support 20. The detection component 40 is electrically connected to the drive mechanism 30 so as to facilitate the control of the start and stop of the drive mechanism 30 according to the state of the panel support 20.

[0090] In this embodiment, combined with Figures 1-5 As shown, the detection component 40 includes two sensors, which are mounted on the track support 10. The two sensors are a first sensor 41 and a second sensor 42. The slider 311 can trigger the first sensor 41 and the second sensor 42 when the panel driving device is in the flip state and the initial state, respectively. Both the first sensor 41 and the second sensor 42 are electrically connected to the driving mechanism 30.

[0091] like Figure 6 As shown, when the panel driving device is in the initial state, the guide shaft 22 is located at the rear end of the first guide groove 111, the slider 311 is located at the rear end of the second guide groove 112, and the slider 311 triggers the second sensor 42. The electrical signal of the second sensor 42 changes, so as to determine that the panel driving device is in the initial state at this time, thereby controlling the start and stop of the driving mechanism 30.

[0092] like Figure 7 As shown, when the panel driving device is in the flip state, the guide shaft 22 is located at the front end of the first guide groove 111, the slider 311 is located at the front end of the second guide groove 112, and triggers the first sensor 41. The electrical signal of the first sensor 41 changes, so as to determine that the panel driving device is in the flip state at this time, thereby controlling the start and stop of the driving mechanism 30.

[0093] In this embodiment, the position of the panel assembly 100 is determined by the cooperation between the slider 311 and the detection component 40, which enables timely control of the start and stop of the drive mechanism 30, thereby improving the motion accuracy of the panel bracket 20 and the overall intelligence of the machine.

[0094] In this embodiment, the first sensing element 41 and the second sensing element 42 are micro switches, and the guide shaft 22 triggers the micro switches by pressing the spring of the micro switches.

[0095] In some other embodiments, the first sensor 41 and the second sensor 42 may also be distance sensors or other sensors, and the sensors are triggered when the distance between the guide shaft 22 and the sensor is within the detection range.

[0096] Optionally, the cooking appliance also includes a controller, and the detection component 40 and the drive component 32 are all electrically connected to the controller. The detection component 40 transmits detection signals to the controller, and the controller controls the start and stop of the drive component 32 according to the received signals.

[0097] Example 2

[0098] This embodiment provides a cooking appliance, which has a structure that is roughly the same as the cooking appliance in Embodiment 1, except that the structure of the detection component 40 is different.

[0099] In this embodiment, two sensors cooperate with the guide shaft 22 to detect the state of the panel bracket 20. For example... Figure 8 As shown, when the panel driving device is in the initial state, the guide shaft 22 is located at the rear end of the first guide groove 111. At this time, the guide shaft 22 triggers the second sensor 42, and the electrical signal of the second sensor 42 changes, so as to facilitate the control of the start and stop of the drive mechanism 30.

[0100] When the panel drive device is in the extended state, the guide shaft 22 moves to the front end of the first guide groove 111. At this time, the guide shaft 22 does not rotate relative to the track bracket 10, and the guide shaft 22 will not trigger the first sensor 41. When the guide shaft 22 rotates to the panel drive device in the flipped state, the guide shaft 22 triggers the first sensor 41, and the electrical signal of the first sensor 41 changes, so as to facilitate the control of the start and stop of the drive mechanism 30.

[0101] In order to ensure that the guide shaft 22 located at the front end of the first guide groove 111 does not trigger the first sensor 41 in the extended state, and triggers the first sensor 41 in the flipped state, as follows: Figure 9 and Figure 10 As shown, the guide shaft 22 includes a shaft body 221 and a trigger portion 222 protruding radially along the shaft body 221. When the panel driving device is in the extended state, the trigger portion 222 extends approximately in a first horizontal direction, and the trigger portion 222 will not trigger the first sensor 41; as Figure 10 As shown, when the panel driving device is in the flip state, the trigger part 222 rotates with the shaft 221 and the angle changes. The trigger part 222 triggers the first sensor 41, and the electrical signal of the first sensor 41 changes, so as to facilitate the control of the start and stop of the drive mechanism 30.

[0102] Example 3

[0103] This embodiment provides a cooking appliance, which has a structure that is roughly the same as the cooking appliance in Embodiment 1, except that the structure of the detection component 40 is different.

[0104] In this embodiment, the detection component 40 includes a stall sensor, which is used to detect whether the drive component 32 is stalled, so as to control the start and stop of the drive component 32 according to the stall status of the drive component 32.

[0105] To ensure the movement accuracy of the panel support 20, when the panel drive device is in the initial state, the slider 311 is located at the rear end of the second guide groove 112. The slider 311 abuts against the rear side wall of the second guide groove 112, preventing the rack 31 from moving further rearward. If the drive mechanism 30 is in the activated state at this time, the drive member 32 will stall. Detecting whether the drive member 32 is stalled allows for the determination that the panel support 20 has been retracted, and timely control of the drive member 32 to stop operation. When the panel drive device is in the flipped state, the slider 311 is located at the front end of the second guide groove 112. The slider 311 abuts against the front side wall of the second guide groove 112, preventing the rack 31 from moving further forward. If the drive mechanism 30 is in the activated state at this time, the drive member 32 will stall. Detecting whether the drive member 32 is stalled allows for the determination that the panel assembly 100 has been lifted, and timely control of the drive member 32 to stop operation.

[0106] Similarly, the state of the panel bracket 20 can also be determined by the cooperation between the guide shaft 22 and the first guide groove 111, combined with the stall detection component, which will not be elaborated here.

[0107] By detecting whether the drive component 32 is stalled, the position status of the panel bracket 20 can be determined, so as to control the start and stop of the drive component 32, which helps to improve the movement accuracy of the panel bracket 20.

[0108] It should be noted that the stall sensor is existing technology in this field. The stall sensor can be a current sensor or an encoder. By detecting the current of the rotating motor through the current sensor or the rotation speed of the rotating motor through the encoder, it is possible to detect whether the rotating motor is stalled.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
