[0012] A second toothed rack extending along the length direction is provided on the inner wall of the first tube;

[0013] A first gear is rotatably connected to the side wall of the second tube. The inner side of the first gear meshes with the first rack, and the outer side of the first gear meshes with the second rack, so that after the second tube rises and falls relative to the first tube, the first gear drives the third tube to rise and fall synchronously relative to the second tube.

[0014] Furthermore, a second gear is provided on the side wall of the second tube, the second gear is located above the first gear, and the inner side of the second gear meshes with the first rack.

[0015] Furthermore, the first swing mechanism includes a rotating module and a connecting arm. The connecting arm includes a first end and a second end that are disposed opposite to each other. The first end is rotatably connected to the lifting end, and the second end is connected to the pot lid.

[0016] The rotation module is located on the lifting end and is used to drive the connecting arm to rotate relative to the lifting end.

[0017] Furthermore, the rotating module includes a second motor, a first bevel gear, and a second bevel gear; the second motor is connected to the lifting end; the first bevel gear is connected to the output shaft of the second motor.

[0021] And / or, the pot lid includes a lid body, a stirrer, and a second oscillating mechanism; the stirrer includes a shaft and stirring blades connected to each other; the shaft is hinged to the bottom surface of the lid body;

[0022] The second swing mechanism is located between the cover and the shaft, and is used to drive the shaft to swing to a vertical or horizontal state.

[0023] Secondly, the present invention provides an integrated stove, including the aforementioned pot lid retraction mechanism.

[0024] Thirdly, the present invention provides an integrated stove control method, comprising the following steps:

[0025] Receive shutdown signal;

[0026] Drive the pot lid to rotate so that the bottom surface of the pot lid changes from a horizontal state to a vertical state;

[0027] Drive the lid to move up and down so that the lid is lowered below the through hole on the countertop.

[0028] This invention has at least the following advantages or beneficial effects:

[0029] The pot lid launching mechanism provided by the present invention includes: a pot lid, a first swing mechanism, a platform, and a lifting mechanism; the first swing mechanism is connected to the pot lid and is used to drive the bottom surface of the pot lid to be in a horizontal or vertical state; a through hole is provided on the platform; the lifting mechanism includes a lifting end that can move up and down; the lifting end is connected to the first swing mechanism and is used to drive the first swing mechanism and the pot lid to move up and down so that the pot lid in the vertical state can pass through the through hole.

[0030] After cooking, the lid can be hidden under the countertop. Initially, the lid is horizontally placed over the pot's opening. A first swing mechanism rotates the lid, changing it from a horizontal to a vertical position and removing it from above the pot's opening. Then, a lifting mechanism lowers the lid through a hole under the countertop, thus hiding it. Conversely, when cooking is needed, the lifting mechanism raises the lid, allowing it to move above the countertop through the hole. The first swing mechanism rotates the lid from a vertical to a horizontal position, then places it over the pot's opening, closing the lid. This solves the problem of lid storage space, improves space utilization, and reduces space occupation. Attached Figure Description

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0049] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0050] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0051] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0052] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0053] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0054] The lid-retracting mechanism provided by this invention can be applied to integrated stoves.

[0055] like Figures 1-3 As shown, the pot lid raising and lowering mechanism includes: pot lid 100, first swing mechanism, table 300 and lifting mechanism 400.

[0056] The countertop 300 can be the countertop 300 of an integrated stove, meaning the countertop 300 has burners. The through hole 310 on the countertop 300 is located to the side of the burner, for example, to the left of the left burner. The through hole 310 can be rectangular, with its length slightly larger than the diameter of the pot lid 100. The through hole 310 is small in size, reducing its footprint on the countertop 300.

[0057] The first swing mechanism is connected to the pot lid 100, and the first swing mechanism is used to drive the bottom surface of the pot lid 100 to a horizontal or vertical state. For example, Figure 2 As shown, in the horizontal position, the bottom surface of the lid 100 is parallel to the horizontal plane, used to mate with the opening of the pot to close the opening. Figure 3 As shown, in the vertical position, the bottom surface of the pot lid 100 is parallel to the vertical plane, meaning the rotation range of the first swing mechanism is 0-90°. The swing range of the pot lid 100 can be limited by a limiting structure to prevent it from exceeding its stroke.

[0058] The bottom of the lifting mechanism 400 is located below the tabletop 300. The lifting mechanism 400 includes a lifting end that can move up and down, i.e., the top of the lifting mechanism 400. The lifting end is connected to the first swing mechanism. The lifting mechanism 400 is used to drive the first swing mechanism and the pot lid 100 to move up and down so that the pot lid 100, which is in a vertical position, can pass through the through hole 310.

[0059] After cooking, the lid 100 can be hidden under the countertop 300. Initially, the lid 100 is horizontally placed over the pot's opening. A first swing mechanism rotates the lid 100, changing it from a horizontal to a vertical position and removing it from above the pot's opening. Then, a lifting mechanism 400 lowers the lid 100 through the through-hole 310 to below the countertop 300, thus hiding it. Conversely, when cooking is needed, the lifting mechanism 400 raises the lid 100, allowing it to pass through the through-hole 310 and move above the countertop 300. The first swing mechanism rotates the lid 100 from a vertical to a horizontal position, then places it over the pot's opening, closing the lid 100. This solves the problem of lid 100 storage space, improves space utilization, and reduces space occupation.

[0060] In this embodiment, the lifting mechanism 400 includes a retractable multi-stage sleeve assembly, which avoids occupying too much vertical space when the multi-stage sleeve assembly is in the retracted state, allowing the integrated stove to be set lower. In other feasible solutions, linear modules, such as lead screw motors, electric push rods, etc., can be used to directly drive the first swing mechanism and the pot lid 100 to lift and lower.

[0061] like Figure 4 and Figure 5As shown, the multi-stage sleeve assembly includes a first tube 410 and a second tube 420 sequentially sleeved from the outside in. When extended, the first tube 410 is located below, and the second tube 420 is located above, with the top of the second tube 420 forming a lifting end. The lifting mechanism 400 also includes a lifting module, which may include a first motor 430 and a first drive end. The first drive end may be a screw 440 coaxially connected to the output shaft of the first motor 430. The screw 440 is threadedly connected to the second tube 420. Through the rotation of the screw 440, torque is transmitted to the second tube 420. The second tube 420 and the first tube 410 can only move linearly and cannot rotate relative to each other. Therefore, the rotating screw 440 can drive the second tube 420 to rise and fall. The first motor 430 is connected to the bottom of the first tube 410. The cross-sectional shape of both the first tube 410 and the second tube 420 can be rectangular to avoid relative rotation.

[0062] In this embodiment, to further increase the stroke of the lifting end, the multi-stage sleeve assembly also includes a third tube 450 located inside the second tube 420, which can move up and down relative to the second tube 420. A first rack 451 extending along its length is provided on the outer wall of the third tube 450; a second rack 411 extending along its length is provided on the inner wall of the first tube 410; a mounting hole is provided on the side wall of the second tube 420, penetrating its inner and outer surfaces, and a first gear 421 is rotatably connected within the mounting hole. The circumferential outer wall of the first gear 421 protrudes from the inner and outer walls of the second tube 420, respectively. The outer side of the first gear 421 meshes with the second rack 411, and the inner side of the first gear 421 meshes with the first rack 451. When extension is required, the first motor 430 drives the screw 440 to rotate, the second tube 420 moves upward, the second rack 411 drives the first gear 421 to rotate, the rotating first gear 421 drives the first rack 451 to move, thereby pushing the third tube 450 upward, and the top of the third tube 450 forms a lifting end.

[0063] The first gear 421 can be provided on both opposite side walls of the second tube 420. Correspondingly, the second rack 411 and the first rack 451 can be provided on both opposite inner side walls of the first tube 410 and both opposite outer side walls of the third tube 450, thereby forming a stable meshing relationship.

[0064] The second tube 420 has a mounting hole on its side wall, and a second gear 422 is installed in the mounting hole. The second gear 422 is located above the first gear 421, and the inner side of the second gear 422 meshes with the first rack 451. The third tube 450 is connected to the second tube 450 from both the top and bottom positions, thereby improving the stability of the third tube 450 in raising and lowering.

[0065] like Figure 6 As shown, the first swing mechanism includes a rotating module and a connecting arm 210. The connecting arm 210 can be elongated and includes a first end and a second end arranged opposite to each other along its length. The first end is rotatably connected to the lifting end, and the second end is fixedly connected to the pot lid 100. The rotating module is located at the lifting end and is used to drive the connecting arm 210 to rotate relative to the lifting end. The rotating module drives the connecting arm 210 to rotate to a horizontal or vertical position, so that the pot lid 100 switches between a horizontal and a vertical state.

[0066] The rotating module includes a second motor 220, a first bevel gear 230, and a second bevel gear 240. The second motor 220 is connected to the lifting end. The first bevel gear 230 is connected to the output shaft of the second motor 220. The connecting arm 210 is connected to the lifting end via a first rotating shaft. The second bevel gear 240 is connected to the first rotating shaft, and the first rotating shaft, the second bevel gear 240, and the connecting arm 210 have the same motion state. The first bevel gear 230 and the second bevel gear 240 mesh.

[0067] like Figure 2 and Figure 6 As shown, a notch is provided on the side wall of the top of the third tube 450 to allow the connecting arm 210 to be rotated to a horizontal position relative to the third tube 450. A second motor 220 is fixedly connected to the inside of the notch, and a first bevel gear 230 is connected to the output shaft of the second motor 220. Both ends of a first rotating shaft are rotatably connected to the third tube 450. The first rotating shaft, the second bevel gear 240, and the connecting arm 210 are fixedly connected and have the same motion state. After the second motor 220 starts, torque is transmitted to the pot lid 100 through the first bevel gear 230, the second bevel gear 240, the first rotating shaft, and the connecting arm 210 to achieve the switching of the pot lid 100's state.

[0068] like Figure 7 As shown, a panel 320 with an opening / closing through-hole 310 is movably connected to the countertop 300. When the panel 320 is in the open state, it is flush with the upper surface of the countertop 300, making the countertop 300 more aesthetically pleasing. The panel 320 can be moved away from the through-hole 310 by a translation mechanism, thereby raising the pot lid 100 below the through-hole 310 above the countertop 300.

[0069] The translation mechanism includes a translation module, a support plate 340, a guide rail 350, a guide column 360, and hinges 370. The bottom surface of the panel 320 has four lifting lugs 380 at its four corners. There are four hinges 370, corresponding one-to-one with the lifting lugs 380. One end of each hinge 370 is hinged to a lifting lug 380 via a first hinge axis, and the other end is hinged to the support plate 340. The guide rail 350 is positioned between the burner head and the through hole 310. The guide rail 350 has a sliding groove extending in the left-right direction, comprising a first section 351 and a second section 352, as shown below. Figure 8 As shown, the first segment 351 extends horizontally, and the second segment 352 extends vertically. The lower end of the second segment 352 is connected to one end of the first segment 351, forming an "L" shape. The guide post 360 is coaxially connected to the first hinge shaft near the guide rail 350, and the guide post 360 is slidably connected in the slide groove. After the translation mechanism moves the support horizontally, the guide post 360 can move horizontally under the drive of the guide groove to below the through hole 310. After the guide post 360 rises to the second segment 352, it drives the first hinge shaft to move upward, thereby causing the panel 320 to move upward and close the through hole 310. Conversely, when it is necessary to open the through hole 310, the support can be driven in the opposite direction. As the guide post 360 moves from the second segment 352, it gradually moves downward, and the panel moves downward accordingly. When the guide post 360 slides into the first segment 351, the panel moves horizontally below the table surface 300. By using a translation method to drive panel 320, the space occupied by panel 320 during movement can be reduced.

[0070] The translation module may include a third motor 330, on which a fourth gear 331 is provided, and on the support plate 340 a fourth rack 341 extending in the left and right direction is provided. The fourth rack 341 meshes with the fourth gear 331, and the third motor 330 drives the support plate 340 to move in the left and right direction.

[0071] like Figures 9-12 As shown, the pot lid 100 includes a lid body 110, a stirrer, and a second swing mechanism; the stirrer includes a shaft 120 and a stirring blade 130 connected to each other; the shaft 120 is hinged to the bottom surface of the lid body 110; the second swing mechanism is disposed between the lid body 110 and the shaft 120, and is used to drive the shaft 120 to swing to a vertical or horizontal state.

[0072] For intelligent cooking cookware, the lid 110 has a stirrer, which includes a shaft 120 and stirring blades 130. The number of stirring blades 130 can be one or two. When there are two blades, the two blades are arranged in a straight line. When the shaft 120 is in a vertical position, the rotating mechanism on the lid 100 can drive the shaft 120 to rotate, thereby stirring the food in the cookware. When cooking is finished and the lid 100 needs to be stored in the through hole 310, the shaft 120 can be rotated 90° to a horizontal position using the second swing mechanism, that is, parallel to the bottom surface of the lid 100. The stirrer is then hidden inside the lid 110, allowing the lid 100 to pass smoothly through the through hole 310.

[0073] Specifically, such as Figure 11 and Figure 12As shown, a rotating mechanism is provided on the cover 110, and the rotating mechanism has a drive shaft 111. The drive shaft 111 has a first hinge portion 1111, and the shaft 120 has a second hinge portion 121. The first hinge portion 1111 and the second hinge portion 121 are hinged by a second hinge shaft 140. The drive shaft 111 has a through hole extending along its length direction. A third rack 1112 is provided in the through hole. The upper end of the third rack 1112 is connected to a linear drive module 1113, which drives the third rack 1112 to move along the length direction of the drive shaft 111. A third gear 1211 is provided on the second hinge portion 121. The third gear 1211 is concentric with the second hinge shaft 140. The third rack 1112 meshes with the third gear 1211, so that the third rack 1112 drives the third gear 1211 to rotate, thereby causing the shaft 120 to swing to a horizontal state and a vertical state.

[0074] In this embodiment, there are two stirring blades 130. The two stirring blades 130 are arranged on opposite sides of the shaft 120 along the same straight line, and the arrangement direction of the two stirring blades 130 is parallel to the second hinge shaft 140.

[0075] The integrated stove provided by the present invention includes the above-mentioned pot lid retraction mechanism.

[0076] The integrated stove control method provided by this invention is executed by a controller and includes the following steps:

[0077] Receive the shutdown signal.

[0078] The signal can be sent by the user or by the timer. For example, when automatic cooking is complete, the timer sends a shut-off signal to the controller.

[0079] Drive the pot lid 100 to rotate so that the bottom surface of the pot lid 100 changes from a horizontal state to a vertical state.

[0080] The controller sends a control command to the first swing mechanism, which causes the first swing mechanism to rotate the pot lid 100 90° to a vertical position.

[0081] Drive the pot lid 100 to move up and down so that the pot lid 100 is lowered below the through hole 310 of the table surface 300.

[0082] The controller sends a command to the lifting mechanism 400, which lowers the pot lid 100 below the through hole 310, thus concealing the pot lid 100. Figure 3 As shown.

[0083] Conversely, when cooking is required, the integrated stove control method includes the following steps: receiving a start signal, driving the pot lid 100 to rise and fall, so that the pot lid 100 rises above the through hole 310 of the countertop 300; driving the pot lid 100 to rotate, so that the bottom surface of the pot lid 100 rotates from a vertical state to a horizontal state, thereby covering the cookware, such as... Figure 2 As shown.

[0084] Furthermore, after "driving the pot lid 100 to rotate so that the bottom surface of the pot lid 100 rotates from a vertical state to a horizontal state", the following steps can be performed:

[0085] The lid 100 is driven to move up and down, causing it to descend and securely fasten to the cookware. Specifically, when the lid 100 rises, it can be raised slightly higher. When rotated to a horizontal position, the bottom surface of the lid 100 is higher than the opening of most cookware. The lid 100 is then lowered to secure it to the cookware, adapting to cookware of different heights. An indirect sensor can be installed on the stirring blade 130 to detect the distance between the stirring blade 130 and the bottom of the cookware, thereby determining whether the lid 100 can be securely fastened.

[0086] Furthermore, the method also includes a step between the two steps of "receiving the start signal" and "driving the lid 100 to rise above the through hole 310 of the tabletop 300": detecting whether there is an obstacle above the panel 320. This can be done by using an image acquisition mechanism to acquire an image above the panel 320 and analyzing the image to determine if there is an obstacle. If an obstacle exists, the panel 320 is not opened. If there is no obstacle, the panel 320 is opened.

[0087] Furthermore, the method also includes a step between the two steps of "opening the panel 320" and "driving the lid 100 to rise above the through hole 310 of the countertop 300": detecting whether there is an obstacle in the rising space above the through hole 310. This can be done by using an image acquisition mechanism to capture an image above the through hole 310 and analyzing the image to determine if an obstacle exists. If an obstacle is present, the step of "driving the lid 100 to rise above the through hole 310 of the countertop 300" is stopped, and an alarm is issued to the user. If no obstacle is present, the step of "driving the lid 100 to rise above the through hole 310 of the countertop 300" is executed.

[0088] When a stirrer is located beneath the lid 100, the method further includes the step of "driving the stirrer to a vertical position" performed after "rotating the bottom surface of the lid 100 from a vertical position to a horizontal position," wherein the stirrer can be used to stir ingredients. The method also includes the step of "driving the stirrer to a horizontal position" performed before "rotating the bottom surface of the lid 100 from a horizontal position to a vertical position," wherein the stirrer can be concealed inside the lid 110 so that the lid 100 can pass through the through-hole 310.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
