Description

Technical Field

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

[0002] In modern kitchens, integrated and intelligent kitchen appliances are increasingly favored by consumers. For example, the microwave-steam-oven combo combines the functions of a microwave oven, steamer, and oven, and can perform multiple cooking tasks such as steaming, baking, frying, and microwaving in one cooking cavity, allowing users to complete diverse cooking in one device.

[0003] In related technologies, cooking equipment includes a main body, a panel, a water tank, and a lifting mechanism. The main body has a cooking cavity and a receiving cavity located above the cooking cavity. The receiving cavity has an opening on the front side facing the main body. The water tank is placed in the receiving cavity through the opening. The panel is movably located at the opening. The lifting mechanism is connected to the panel and includes a support, a moving arm, and a drive mechanism. The support is connected to the main body and has a guide groove extending along the front-rear direction of the main body. The front end of the moving arm is connected to the panel, and the rear side wall of the moving arm has a guide post that is slidably located in the guide groove. The drive mechanism drives the moving arm to reciprocate relative to the support along the extension direction of the guide groove, thereby causing the panel to open or close the opening.

[0004] However, in related technologies, the stability of the moving arm when driving the panel is poor, which leads to technical problems such as poor reliability and stability of the panel opening or closing. Utility Model Content

[0005] In view of the above problems, embodiments of this application provide a cooking device for improving the reliability and stability of panel movement.

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

[0007] This application provides a cooking device, including a device body, a panel, and a lifting mechanism. The panel is located on the front side of the device body, and the lifting mechanism includes a bracket, a moving arm, and a drive unit. The bracket is used to be fixedly connected to the device body and extends along the front-rear direction of the device body.

[0008] The front end of the motion arm is connected to the rear side of the panel and is configured to move back and forth relative to the support. The power output end of the drive unit is connected to the motion arm.

[0009] The moving arm has a first guide groove and a second guide groove along its length, and both of them have a local curvature in the extension direction to form a height difference in the vertical direction; the bracket is provided with at least two guide posts that can slide and match the first guide groove and the second guide groove respectively; and the first guide groove and the second guide groove are arranged vertically at intervals and staggered in the vertical direction.

[0010] In the cooking device provided in this application embodiment, the support in the lifting mechanism is fixedly connected to the device body. The front end of the moving arm is connected to the rear side of the panel. The moving arm has a first guide groove and a second guide groove along its length. The first guide groove and the second guide groove are arranged vertically at intervals and staggered in the vertical direction. Both of them have a local curvature in the extension direction to form a height difference in the vertical direction. The support is provided with at least two guide columns that can slide and match the first guide groove and the second guide groove respectively. The guide columns jointly support the rear end of the moving arm to improve the problem of poor stability of the moving arm caused by the front side of the moving arm being solely subjected to the weight of the panel. In addition, when the driving unit drives the moving arm to move relative to the support in the front and back directions, the moving arm moves along the extension trajectory of the first guide groove and the second guide groove, which improves the reliability and stability of the moving arm driving the panel to move, thereby improving the reliability and stability of the moving arm driving the panel to switch between the open and closed states.

[0011] In some embodiments, the first guide groove is located above the second guide groove, and the second guide groove portion is located in front of the first guide groove, and the curved areas of the two overlap in projection on the same horizontal plane.

[0012] This allows the panel to flip vertically as the moving arm moves back and forth.

[0013] In some embodiments, the rear end of the second guide groove is provided with an upwardly extending limiting notch. When the moving arm drives the panel to the open state, the corresponding guide post is constrained within the limiting notch to limit the movement of the moving arm in the front-back direction.

[0014] In this way, when the panel is in the open position, the moving arm is locked to prevent the panel from moving due to its own weight.

[0015] In some embodiments, the power output end of the drive unit has a drive wheel, and the moving arm has a force-receiving part that cooperates with the drive wheel. The extension trajectory of the force-receiving part is consistent with the extension trajectories of the first guide groove and the second guide groove. The drive wheel is in direct contact with the force-receiving part so as to drive the moving arm to move under its own rotation.

[0016] In this way, the drive wheel and the motion arm are in direct contact, which shortens the transmission path of the driving force, reduces the error in the transmission of the driving force, and thus improves the reliability of driving the motion arm.

[0017] In some embodiments, the front end of the force-receiving part is vertically aligned with the front end of the first guide groove, and the rear end of the force-receiving part is vertically aligned with the rear end of the first guide groove.

[0018] This improves the stability of the support for the moving arm and the smoothness of the movement.

[0019] In some embodiments, the force-bearing portion is located on the outer edge of the moving arm.

[0020] This ensures the structural strength of the motion arm.

[0021] In some embodiments, the drive wheel is located above the moving arm, and the force-bearing part is located at the upper edge of the moving arm.

[0022] In this way, the drive wheel will not be subjected to pressure from the moving arm and the panel during rotation, thereby improving the overall reliability and service life of the drive unit.

[0023] In some embodiments, the rear end of the force-bearing portion has a clearance notch for avoiding the drive wheel.

[0024] This prevents interference between the drive wheel and the rear end of the force-bearing part, thus affecting the travel of the drive wheel.

[0025] In some embodiments, the drive wheel is a drive gear, the force-bearing part is a tooth, and the drive gear meshes with the tooth.

[0026] This improves the reliability and accuracy of the drive wheel's motion of the moving arm.

[0027] In some embodiments, the first guide groove, the second guide groove, and the force-receiving part all have the same curvature in their extension directions, and each curvature is a circular arc, and each circular arc has the same center.

[0028] This can further improve the reliability and smoothness of the movement of the arm.

[0029] In some embodiments, the extension trajectories of the first guide groove, the second guide groove, and the force-bearing part each include a straight line segment and an arc segment connected sequentially in the front-back direction. The arc segment is formed on the arc segment, and the arc segment is located behind the corresponding straight line segment. At least the rear end of the arc segment is higher than the straight line segment connected to it in the vertical direction.

[0030] This can further improve the accuracy and reliability of the movement path of the moving arm in the forward and backward direction.

[0031] In some embodiments, the motion arm is a non-metallic arm.

[0032] This can improve the noise caused by poor lubrication during the movement of the motion arm.

[0033] In some embodiments, the support has a sliding gap extending through the front-rear direction of the cooking device, the rear end of the moving arm is located within the sliding gap, and the front end of the moving arm is always located outside the sliding gap.

[0034] This protects the arm while improving the overall aesthetics.

[0035] In some embodiments, a plurality of first reinforcing ribs are provided between the second guide groove and the first guide groove, and a plurality of second reinforcing ribs are provided between the first guide groove and the tooth portion, wherein the plurality of first reinforcing ribs and the plurality of second reinforcing ribs are arranged at intervals along the front-back direction.

[0036] This can improve the structural strength of the dynamometer arm.

[0037] In some embodiments, the bracket is provided with a first micro switch and a second micro switch at intervals along the front-rear direction, and the first micro switch is located between the second micro switch and the panel;

[0038] The side wall of the moving arm has a trigger rod. When the moving arm moves the panel to the open state, the trigger rod triggers the second micro switch; when the moving arm moves the panel to the closed state, the trigger rod triggers the first micro switch.

[0039] In this way, users can know precisely and directly whether the panel has reached the open or closed position.

[0040] In some embodiments, there are two supports and two moving arms. The two supports are spaced apart along the width direction of the panel, and one support corresponds to one moving arm. The front ends of both moving arms are connected to the rear side of the panel.

[0041] The drive unit has two power output terminals, which are respectively connected to the two motion arms.

[0042] This improves the stability and reliability of the panel's movement.

[0043] 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.

[0067] 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, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0068] This application provides a cooking device, which includes, but is not limited to, a steam oven, a baking oven, and corresponding combination models, such as a microwave-steam-oven combination machine, a steam-oven combination machine, a microwave-steam combination machine, etc.

[0069] Generally, cooking equipment includes a main body, an inner pot, a control panel, and a lifting mechanism. The inner pot has a cooking chamber into which high-temperature airflow or steam is introduced to achieve the cooking function. The control panel is located on the front of the main body and above the inner pot, allowing users to operate the cooking functions. Taking a cooking equipment with a steaming function as an example, it also includes a water tank and a steam generator. The water tank supplies water to the steam generator, which generates high-temperature steam and delivers it to the cooking chamber to achieve the steaming function. To improve the structural compactness of the cooking equipment, the inner pot has a receiving cavity with an opening at the front. The water tank is housed in this cavity, and the control panel is movably positioned at the opening. The lifting mechanism moves the control panel to open or close the opening, thereby improving the structural compactness and space utilization of the cooking equipment.

[0070] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 As shown, the lifting mechanism 10 for the cooking device panel 20 provided in this application includes a bracket 100, a moving arm 200, and a drive unit 300. The bracket 100 is fixedly connected to the cooking device and extends along the front-rear direction of the cooking device. The front end of the moving arm 200 is connected to the rear side of the panel 20, and the moving arm 200 can move back and forth relative to the bracket 100. The power output end of the drive unit 300 is drivenly connected to the moving arm 200. For example, the drive unit 300 includes a drive motor 320 and a drive wheel 310. The drive wheel 310 is connected to the output shaft of the drive motor 320 and is directly connected to the moving arm 200. The drive motor 320 rotates forward or backward, so that the drive wheel 310 can rotate forward or backward around its own axis, thereby driving the moving arm 200 to move the panel 20 forward or backward, so that the panel 20 is in an open or closed state.

[0071] It should be noted that the front and back directions referred to in this article refer to the same direction as the front and back of the cooking equipment.

[0072] Among them, such as Figure 1 and Figure 2 As shown, there are two supports 100 and two moving arms 200. The two supports 100 are spaced apart along the width direction of the panel 20, and one support 100 corresponds to one moving arm 200. The front ends of the two moving arms 200 are connected to the two ends of the rear side of the panel 20. The drive unit 300 has two power output ends, which are respectively connected to the two moving arms 200. That is to say, the two moving arms 200 jointly drive the panel 20 to move, which can improve the stability and reliability of the movement of the panel 20.

[0073] Please refer to Figure 3 and Figure 4As shown, the motion arm 200 (e.g.) Figure 1 and Figure 2 The upper and lower directions of the moving arm 200 are provided with a first guide groove 210 and a second guide groove 220 arranged at intervals. Both the first guide groove 210 and the second guide groove 220 are along the length direction of the moving arm 200 (e.g., in the upper and lower directions). Figure 3 and Figure 4 The first guide groove 210 and the second guide groove 220 extend in the front-back direction, and both have a partial curvature in the extension direction. For example, both the first guide groove 210 and the second guide groove 220 have at least a partial arc or elliptical arc, so that the extension directions of the first guide groove 210 and the second guide groove 220 form a height difference in the vertical direction. For example, the rear end of both the first guide groove 210 and the second guide groove 220 is higher than the front end. Furthermore, the first guide groove 210 and the second guide groove 220 are arranged vertically at intervals and staggered in the vertical direction. In addition, as... Figure 2 and Figure 3 As shown, the bracket 100 is provided with at least two guide posts that can slide and match the first guide groove 210 and the second guide groove 220 respectively. For example, the at least two guide posts include a first guide post 110 and a second guide post 120. The first guide post 110 and the second guide post 120 are fixedly arranged relative to the bracket 100. The first guide post 110 is located in the first guide groove 210 and contacts the upper and lower groove walls of the first guide groove 210. The second guide post 120 is located in the second guide groove 220 and contacts the upper and lower groove walls of the second guide groove 220. When the drive wheel 310 drives the moving arm 200 to move back and forth relative to the bracket 100, the first guide post 110 slides relative to the first guide groove 210, and the second guide post 120 slides relative to the second guide groove 220 to guide the movement of the moving arm 200.

[0074] Since the first guide groove 210 and the second guide groove 220 both have a height difference in the vertical direction, and both the rear end of the first guide groove 210 and the front end of the second guide groove 220 are higher than the front end, when the moving arm 200 drives the panel 20 to move along the extension direction of the first guide groove 210 and the second guide groove 220, in addition to displacement in the front-to-back direction, there is also displacement in the vertical direction. This causes the panel 20 to move forward and flip upward during the opening process until the panel 20 moves to the open state (e.g., ...). Figure 5 As shown); when the moving arm 200 drives the panel 20 to move backward, the panel 20 moves backward and downward until the panel 20 moves to the closed state (as shown). Figure 6 (As shown).

[0075] In addition, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the first guide groove 210 and the second guide groove 220 are spaced apart and staggered in the vertical direction. Therefore, the first guide post 110 and the second guide post 120 are staggered in the vertical direction. In this way, in addition to guiding each other with the corresponding first guide groove 210 and second guide groove 220, the first guide post 110 and the second guide post 120 can provide a supporting foundation for the moving arm 200. Moreover, the first guide post 110 and the second guide post 120 always support the moving arm 200 at different positions in the front-back direction and the vertical direction, thereby improving the structural strength of the moving arm 200 and enhancing its stability and reliability.

[0076] It should be noted that since the panel 20 is connected to the front end of the motion arm 200, the motion arm 200 forms a cantilever beam-like structure under the weight of the panel 20 itself, resulting in uneven force distribution in the front-back direction. By setting the first guide groove 210 and the second guide groove 220 on the motion arm 200, the first guide post 110 and the second guide post 120 on the bracket 100 are respectively supported in the corresponding first guide groove 210 and second guide groove 220, and the first guide post 110 and the second guide post 120 are staggered in the front-back direction and vertical direction. In this way, different positions of the motion arm 200 can be supported to improve the balance of the motion arm 200 in the front-back direction, improve the problem of uneven force distribution in the front-back direction, and thus improve the overall stability of the motion arm 200.

[0077] In some embodiments, the surfaces of the first guide post 110 and the second guide post 120 may be coated with a wear-resistant layer. Correspondingly, the upper and lower walls of the first guide groove 210 and the second guide groove 220 may also be coated with a wear-resistant layer to reduce wear and improve wear resistance, thereby improving the motion reliability, stability and service life of the motion arm 200, and further improving the reliability and stability of the motion arm 200 in driving the panel 20 to switch between the open and closed states.

[0078] In other embodiments, at least the area corresponding to the first guide post 110 and the first guide groove 210 is fitted with a first bushing, and at least the area corresponding to the second guide post 120 and the second guide groove 220 is fitted with a second bushing. For example, the first bushing is fitted on the peripheral wall of the first guide post 110, and the second bushing is fitted on the peripheral wall of the second guide post 120. The first bushing and the second bushing have good wear resistance and rigidity, avoiding the impact of wear-induced errors on the stability, reliability and motion accuracy, and further improving the support reliability, stability and reliability of the motion arm 200.

[0079] In addition, the motion arm 200 has a force-receiving part 230 that matches the drive wheel 310. The extension trajectory of the force-receiving part 230 is consistent with the extension trajectory of the first guide groove 210 and the second guide groove 220. The drive wheel 310 is in direct contact with the force-receiving part 230 on the motion arm 200 to drive the motion arm 200 to move. The drive wheel 310 is arranged adjacent to one of the first guide post 110 and the second guide post 120. In this way, the drive wheel 310 is in direct contact with the motion arm 200, which shortens the transmission path of the driving force, reduces the error of the driving force transmission, and thus improves the reliability of driving the motion arm 200 to move.

[0080] In some embodiments, the force-bearing part 230 is located on the outer edge of the motion arm 200, so that there is no need to open slots or holes on the motion arm 200, thus ensuring the structural strength of the motion arm 200.

[0081] As an example, the drive wheel 310 is located above the motion arm 200, and the force-bearing part 230 is located on the upper edge of the motion arm 200. Since the drive wheel 310 is coaxially connected to the output shaft of the drive motor 320, when the drive wheel 310 is not subjected to pressure from the motion arm 200 and the panel 20 and other components, the output shaft of the drive motor 320 can be prevented from being deformed or damaged due to external pressure, thus extending the service life of the drive motor 320 and improving the overall reliability and service life of the drive unit 300.

[0082] In another example, when the output shaft of the drive motor 320 has greater strength, the drive wheel 310 can also be located below the moving arm 200, that is, the force-bearing part 230 is located at the lower outer edge of the moving arm 200; or, the drive wheel 310 can also directly contact the outer edge of other positions of the moving arm 200, without any specific restrictions.

[0083] In some embodiments, the drive wheel 310 and the force-receiving part 230 are in frictional engagement, that is, when the drive wheel 310 rotates around its own axis, friction is generated between it and the force-receiving part 230, thereby driving the motion arm 200 to move in the front-back direction.

[0084] In other embodiments, the force-receiving part 230 is a toothed part, and the drive wheel 310 is a drive gear. The drive gear meshes with the toothed part. In this way, when the drive gear rotates around its own axis, it can drive the toothed part to drive the moving arm 200 to move in the front-back direction, which improves the reliability of the drive wheel 310 driving the moving arm 200 and avoids the problem of slippage and other phenomena that would prevent the moving arm 200 from moving.

[0085] For example, in Figure 3 , Figure 4 , Figure 5 as well as Figure 6As shown, the drive wheel 310 is a drive gear, and the force-receiving part 230 is a toothed part. The toothed part is located at the upper edge of the moving arm 200 and extends along the front-back direction at the upper edge of the moving arm 200. The drive gear is located above the moving arm 200 and meshes with the toothed part. In this way, when the drive motor 320 rotates forward or backward, the drive gear rotates forward or backward around its own axis, so that the moving arm 200 moves forward or backward.

[0086] The teeth can be formed directly on the upper edge of the motion arm 200 by integral molding or cutting; or they can be a separate rack, which is set on the upper edge of the motion arm 200 by welding, bonding or integral molding. No specific restrictions are made here.

[0087] Please continue to refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the extension trajectories of the first guide groove 210, the second guide groove 220, and the force-receiving part 230 have the same curvature. This curvature includes, but is not limited to, the curvature formed by circular arcs, elliptical arcs, and other arcs. That is, the same curvature of the extension trajectories of the first guide groove 210, the second guide groove 220, and the force-receiving part 230 has the same arc center, i.e., the arc centers of the three coincide. The first guide post 110, the second guide post 120, and the drive wheel 310 are arranged in a staggered arrangement in the radial direction with the same curvature. The first guide post 110, the second guide post 120, and the drive wheel 310 all move around the same arc center. The first guide post 110, the second guide post 120, and the drive wheel 310 are distributed at different positions of the moving arm 200, forming a triangular support. This improves the accuracy and reliability of the moving arm 200's forward and backward movement path, avoids jamming, and enhances the reliability of the first guide post 110 and the second guide post 120's support for the moving arm 200, thereby improving the overall stability and reliability of the moving arm 200.

[0088] In some embodiments, the first guide groove 210 is located above the second guide groove 220, and a portion of the structure of the second guide groove 220 is located in front of the first guide groove 210, and the arcuate regions of the two overlap in the projection portion on the same horizontal plane, so as to improve the smoothness and motion continuity of the motion arm 200.

[0089] For example, the first guide groove 210, the second guide groove 220 and the force-receiving part 230 are all arcs, and each arc has the same center, which further improves the accuracy and reliability of the movement path of the motion arm 200 in the front-back direction and the up-down flipping of the panel, and avoids jamming.

[0090] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the extension trajectories of the first guide groove 210, the second guide groove 220, and the force-receiving part 230 all include straight line segments and arc segments connected sequentially in the front-back direction. The arcs in the first guide groove 210, the second guide groove 220, and the force-receiving part 230 are all formed on their respective corresponding arc segments. The arc segments are located behind their corresponding straight line segments, and at least the rear end of the arc segment is higher than the straight line segment it is connected to in the vertical direction. The centers of the arc segments in the extension trajectories of the first guide groove 210, the second guide groove 220, and the force-receiving part 230 coincide. This reduces the processing difficulty of the first guide groove 210, the second guide groove 220, and the force-receiving part 230. At the same time, it can further improve the accuracy and reliability of the movement path of the motion arm 200 in the front-back direction, thereby improving the stability and reliability of the motion arm 200.

[0091] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, at the rear end of one of the first guide groove 210 and the second guide groove 220, a limiting notch 240 extending vertically upward is provided. When the moving arm 200 drives the panel 20 to the open state, the guide post in the guide groove with the limiting notch 240 is constrained within the limiting notch 240 to limit the movement of the moving arm 200 in the front-back direction. In this way, when the panel 20 is in the open state, the moving arm 200 is locked to prevent the moving arm 200 from driving the panel 20 to move due to the weight of the panel 20 itself, thereby improving the stability of the panel 20 in the open state.

[0092] For example, in Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the force-receiving part 230 is located on the upper edge of the moving arm 200. The first guide groove 210 is located between the second guide groove 220 and the force-receiving part 230, and the front end of the second guide groove 220 is located in front of the first guide groove 210 and the front end of the force-receiving part 230. The limiting notch 240 is opened at the rear end of the arc segment in the second guide groove 220. In this way, the first guide post 110, the second guide post 120 and the drive wheel 310 always form a triangular support for the moving arm 200, thereby improving the stability of the moving arm 200.

[0093] Please refer to Figure 4 , Figure 6 and Figure 7 As shown, the rear end of the force-bearing part 230 has a clearance notch 280 for avoiding the drive wheel 310. This prevents the drive wheel 310 from interfering with the rear end of the force-bearing part 230, thereby affecting the travel of the drive wheel 310.

[0094] In addition, the motion arm 200 can be made of metal or a non-metallic material with high strength. For example, the motion arm 200 is made of metal, which can improve the structural strength and rigidity of the motion arm 200. For another example, the motion arm 200 is made of a non-metallic arm with high strength and rigidity. In this way, when there is poor lubrication between the motion arm 200 and the first guide post 110 and the second guide post 120, there will be no noise generated by mutual friction, thereby improving the user experience.

[0095] To further improve the structural strength of the motion arm 200, in some embodiments, please refer to... Figure 7 As shown, a plurality of first reinforcing ribs 260 are arranged at intervals along the front-back direction between the first guide groove 210 and the second guide groove 220, and a plurality of second reinforcing ribs 270 are arranged at intervals along the front-back direction between the first guide groove 210 and the tooth. Both the first reinforcing ribs 260 and the second reinforcing ribs 270 extend vertically to prevent the tooth from deforming due to the pressure of the drive gear, and to prevent the upper groove wall of the first guide groove 210 and the upper groove wall of the second guide groove 220 from deforming, thereby improving the overall stability and reliability of the moving arm 200.

[0096] Please refer to Figure 1 and Figure 2 As shown, the bracket 100 has a sliding gap that runs through the front and back of the cooking device. The rear end of the moving arm 200 is located inside the sliding gap, and the front end of the moving arm 200 is always located outside the sliding gap. This can protect the moving arm 200 and improve the overall aesthetics.

[0097] Please refer to Figures 1 to 3 As shown, the bracket 100 includes two sub-brackets 100a extending in the same direction as the extension direction of the motion arm 200. The two sub-brackets 100a are located on opposite sides of the motion arm 200 and are detachably connected. The two sub-brackets 100a together form a sliding gap. The first guide post 110 passes through the first guide groove 210 and is connected to at least one of the two sub-brackets 100a. The second guide post 120 passes through the second guide groove 220 and is connected to at least one of the two sub-brackets 100a. This reduces the installation difficulty of the first guide post 110 and the second guide post 120 and increases the installation versatility to meet the needs of different scenarios.

[0098] In addition, such as Figure 8 and Figure 9 As shown, the two sub-supports 100a are detachably connected by fasteners 600 to facilitate the maintenance, repair, and replacement of the motion arm 200 between the two supports 100.

[0099] like Figure 8 and Figure 9 As shown, the drive motor 320 is fixed to the bracket 100 along the width direction of the panel 20 (e.g., Figure 1 and Figure 2 The drive motor 320 is located on the side of the two supports 100 (in the left and right directions). For example, the drive motor 320 is located on the side of the two supports 100 that are adjacent to each other. In this way, the space between the two supports 100 can be effectively utilized without increasing the overall volume of the lifting mechanism 10, thereby reducing the overall volume of the cooking equipment.

[0100] In addition, the output shaft of the drive motor 320 can be directly connected to the drive wheel 310, or it can be connected through a transmission gear set. That is, the output shaft of the drive motor 320 is connected to the input end of the transmission gear set, and the output end of the transmission gear set is connected to the drive wheel 310. The specific design can be flexibly designed according to the spatial layout, and no specific restrictions are imposed here.

[0101] In some embodiments, please refer to Figure 10 and Figure 11 As shown, the bracket 100 is provided with a first micro switch 400 and a second micro switch 500 at intervals along the front-to-back direction, and the first micro switch 400 is located between the second micro switch 500 and the panel 20; the side wall of the moving arm 200 has a trigger rod 250. When the moving arm 200 moves the panel 20 to the open state, the trigger rod 250 triggers the second micro switch 500; when the moving arm 200 moves the panel 20 to the closed state, the trigger rod 250 triggers the first micro switch 400. In this way, the user can accurately and directly know whether the panel 20 has reached the open or closed position.

[0102] For example, such as Figure 10 and Figure 11 As shown, the first micro switch 400 and the second micro switch 500 are both disposed on the side of the two brackets 100 facing each other, and each bracket 100 has a clearance space 130 to avoid the trigger rod 250 that moves with the moving arm 200.

[0103] In summary, the lifting mechanism for a cooking device panel provided in this application embodiment has a support fixedly connected to the device body. The front end of the moving arm is connected to the rear side of the panel. The moving arm has a first guide groove and a second guide groove along its length. The first guide groove and the second guide groove are arranged vertically at intervals and staggered in the vertical direction. Both of them have a local curvature in the extension direction to form a height difference in the vertical direction. The support is provided with at least two guide posts that can slide and match the first guide groove and the second guide groove respectively. The guide posts jointly support the rear end of the moving arm to improve the problem of poor stability of the moving arm caused by the front side of the moving arm being solely subjected to the weight of the panel. In addition, when the driving unit drives the moving arm to move relative to the support in the front and back directions, the moving arm moves along the extension trajectory of the first guide groove and the second guide groove, which improves the reliability and stability of the moving arm driving the panel to move, thereby improving the reliability and stability of the moving arm driving the panel to switch between the open and closed states.
