[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0049] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0051] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0052] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only 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 the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] The pot cover retracting and releasing mechanism provided by the present invention can be applied to integrated stoves.

[0055] like Figure 1 - Figure 3 As shown, the pot cover retracting and releasing mechanism includes: a pot cover 100 , a first swinging mechanism, a table top 300 and a lifting mechanism 400 .

[0056] The tabletop 300 may be a tabletop 300 of an integrated stove, that is, a burner is provided on the tabletop 300. The through hole 310 on the tabletop 300 is located on the side of the burner, for example, on the left side of the left burner. The through hole 310 may be in the shape of a rectangular parallelepiped, and its length is slightly larger than the diameter of the pot cover 100. The through hole 310 is small in size, which reduces the occupation of the tabletop 300.

[0057] The first swing mechanism is connected to the pot cover 100, and the first swing mechanism is used to drive the bottom surface of the pot cover 100 to be in a horizontal state or a vertical state. Figure 2 As shown, in a horizontal state, the bottom surface of the pot cover 100 is parallel to the horizontal plane, and is used to cooperate with the opening of the pot to close the opening of the pot. Figure 3 As shown, in the vertical state, the bottom surface of the pot cover 100 is parallel to the vertical plane, that is, the rotation range of the first swing mechanism is 0-90 degrees. The swing range of the pot cover 100 can be limited by a limiting structure to avoid exceeding the stroke of the pot cover 100.

[0058] The bottom of the lifting mechanism 400 is located below the table 300, and the lifting mechanism 400 includes a lifting end that can move up and down, that is, the top of the lifting mechanism 400. The lifting end is connected to the first swing mechanism, and the lifting mechanism 400 is used to drive the first swing mechanism and the pot cover 100 to move up and down, so that the pot cover 100 in a vertical state passes through the through hole 310.

[0059] When the user finishes cooking, the pot cover 100 can be hidden under the countertop 300. Specifically, initially, the pot cover 100 is horizontally buckled on the opening of the pot, and the pot cover 100 is rotated by the first swing mechanism so that the pot cover 100 is switched from a horizontal state to a vertical state and is moved away from the opening of the pot; then the lifting mechanism 400 is used to drive the pot cover 100 to descend through the through hole 310 to the bottom of the countertop 300, thereby achieving hiding. Conversely, when cooking is required, the lifting mechanism 400 can drive the pot cover 100 to rise so that the pot cover 100 passes through the through hole 310 and moves above the countertop 300. The first swing mechanism drives the pot cover 100 to rotate from a vertical state to a horizontal state, and then buckles the pot cover on the opening of the pot to complete the closure of the pot cover 100. The storage space problem of the pot cover 100 is solved, space utilization is improved, and occupancy is reduced.

[0060] In this embodiment, the lifting mechanism 400 includes a retractable multi-stage sleeve assembly, so that when the multi-stage sleeve assembly is in a retracted state, it can avoid occupying too much vertical space, and the integrated stove can be set lower. In other feasible solutions, a linear module, such as a screw motor, an electric push rod, etc., can also be directly used to directly drive the first swing mechanism and the pot cover 100 to rise and fall.

[0061] like Figure 4 and Figure 5As shown, the multi-stage sleeve assembly includes a first tube body 410 and a second tube body 420 which are sleeved in sequence from the outside to the inside. After extension, the first tube body 410 is located at the bottom, and the second tube body 420 is located at the top. The top of the second tube body 420 forms a lifting end. The lifting mechanism 400 also includes a lifting module. The lifting module may include a first motor 430 and a first driving end. The first driving end may be a screw rod 440 coaxially connected to the output shaft of the first motor 430. The screw rod 440 is threadedly connected to the second tube body 420. Through the rotation of the screw rod 440, the torque is transmitted to the second tube body 420. The second tube body 420 and the first tube body 410 can only perform linear motion but not relative rotation. Therefore, the second tube body 420 can be driven to rise and fall by the rotating screw rod 440. The first motor 430 is connected to the bottom of the first tube body 410. The cross-sections of the first tube body 410 and the second tube body 420 may both be rectangular to avoid relative rotation.

[0062] In this embodiment, in order to further increase the stroke of the lifting end, the multi-stage sleeve assembly further includes a third tube body 450 located inside the second tube body 420, and the third tube body 450 can perform lifting and lowering motion relative to the second tube body 420. A first rack 451 extending along the length direction of the third tube body 450 is provided on the outer wall of the third tube body 450; a second rack 411 extending along the length direction of the first tube body 410 is provided on the inner wall of the first tube body 410; a mounting hole is provided on the side wall of the second tube body 420, and the mounting hole penetrates the inner and outer surfaces thereof, and a first gear 421 is rotatably connected in the mounting hole, and the circumferential outer wall of the first gear 421 protrudes from the inner and outer walls of the second tube body 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 body 420 moves upward, the second rack 411 drives the first gear 421 to rotate, and the rotating first gear 421 drives the first rack 451 to move, thereby pushing the third tube body 450 upward, and the top of the third tube body 450 forms a lifting end.

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

[0064] A mounting hole is provided on the side wall of the second tube body 420, and a second gear 422 is provided in the mounting hole. The second gear 422 is located above the first gear 421, and the inner side of the second gear 422 is meshed with the first rack 451, and the third tube body 450 is meshed and connected from two positions, thereby improving the stability of the lifting and lowering of the third tube body 450.

[0065] like Figure 6 As shown, the first swing mechanism includes a rotating module and a connecting arm 210. The connecting arm 210 may be in the shape of a long strip, and the connecting arm 210 includes a first end and a second end arranged oppositely along its length direction. The first end is rotatably connected to the lifting end, and the second end is fixedly connected to the pot cover 100. The rotating module is arranged 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 the horizontal or vertical state, so that the pot cover 100 is switched to the horizontal state and the 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 through the 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 is meshed with the second bevel gear 240.

[0067] like Figure 2 and Figure 6 As shown, a notch is provided on the side wall at the top of the third tube body 450 to avoid the connecting arm 210, so that the connecting arm 210 can rotate to a horizontal position relative to the third tube body 450. The second motor 220 is fixedly connected to the inner side of the notch, and the first bevel gear 230 is connected to the output shaft of the second motor 220. Both ends of the first rotating shaft are rotatably connected to the third tube body 450, and 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 is started, the torque is transmitted to the pot cover 100 through the first bevel gear 230, the second bevel gear 240, the first rotating shaft and the connecting arm 210 to realize the switching of the state of the pot cover 100.

[0068] like Figure 7 As shown, a panel 320 for opening and closing the through hole 310 is movably connected to the table 300. When the panel 320 is in an open state, it is flush with the upper surface of the table 300, thereby making the table 300 more beautiful. The panel 320 can be moved away from the through hole 310 under the drive of the translation mechanism, so that the pot cover 100 below the through hole 310 rises above the table 300.

[0069] The translation mechanism includes a translation module, a support plate 340, a guide rail 350, a guide column 360 and a hinge 370. The four corners of the bottom surface of the panel 320 are respectively provided with lifting ears 380. There are four hinges 370, which correspond to the lifting ears 380 one by one. One end of the hinge 370 is hinged to the lifting ear 380 through a first hinge axis, and the other end is hinged to the support plate 340. The guide rail 350 is set at a position between the furnace head and the through hole 310. The guide rail 350 is provided with a slide groove extending in the left and right direction. The slide groove includes a first section 351 and a second section 352. Figure 8 As shown, the first section 351 extends in the horizontal direction, the second section 352 extends in the vertical direction, the lower end of the second section 352 is connected to one end of the first section 351, and the first section 351 and the second section 352 are connected to form an "L" shape. The guide column 360 is coaxially connected to the first hinge shaft near the guide rail 350, and the guide column 360 is slidably connected in the slide groove. After the translation mechanism moves the bracket horizontally, the guide column 360 can be driven by the guide groove to move horizontally to the bottom of the through hole 310, and after the guide column 360 moves upward to the second section 352, the guide column 360 drives the first hinge shaft to move upward, so that the panel 320 moves upward and closes the through hole 310. Conversely, when the through hole 310 needs to be opened, the bracket can be driven in the reverse direction, and the guide column 360 gradually moves downward during the movement from the second section 352, and the board surface moves downward accordingly. When the guide column 360 slides into the first section 351, the board surface is translated to the bottom of the table 300. By driving the panel 320 in a translational manner, the space occupied by the panel 320 when it moves can be reduced.

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

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

[0072] For the smart cooking pot, the cover 110 thereof is provided with a stirrer, which includes a shaft 120 and a stirring blade 130. The number of stirring blades 130 can be one or two. When there are two, the two blades are arranged in a straight line. When the shaft 120 is in a vertical state, the rotating mechanism on the pot cover 100 can drive the shaft 120 to rotate, thereby stirring the ingredients in the pot; when cooking is completed and the pot cover 100 needs to be stored in the through hole 310, the shaft 120 can be rotated 90° to a horizontal state by using the second swing mechanism, that is, parallel to the bottom surface of the pot cover 100, and the stirrer is hidden inside the cover 110, so that the pot cover 100 can pass through the through hole 310 smoothly.

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

[0074] In this embodiment, the number of the stirring blades 130 is two. The two stirring blades 130 are disposed along the same straight line at two opposite sides of the shaft 120 , 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 comprises the above-mentioned pot cover retracting and releasing mechanism.

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

[0077] Receive a shutdown signal.

[0078] The signal may be sent by the user or by a timer, for example, when automatic cooking is completed, the timer sends a shut-down signal to the controller.

[0079] The pot cover 100 is driven to rotate so that the bottom surface of the pot cover 100 rotates from a horizontal state to a vertical state.

[0080] The controller sends a control instruction to the first swing mechanism, so that the first swing mechanism rotates the pot cover 100 90° to a vertical state.

[0081] The pot cover 100 is driven to move up and down so that the pot cover 100 is lowered to below the through hole 310 of the table top 300 .

[0082] The controller sends a command to the lifting mechanism 400, and the lifting mechanism 400 drives the pot cover 100 to descend below the through hole 310 to hide the pot cover 100. Figure 3 shown.

[0083] On the contrary, when cooking is required, the integrated stove control method includes the steps of: receiving a start signal, driving the pot cover 100 to move up and down, so that the pot cover 100 rises to above the through hole 310 of the table 300; driving the pot cover 100 to rotate, so that the bottom surface of the pot cover 100 rotates from a vertical state to a horizontal state, so as to cover the pot, such as Figure 2 shown.

[0084] Further, after “driving the pot cover 100 to rotate so that the bottom surface of the pot cover 100 rotates from a vertical state to a horizontal state”, the following steps may be performed:

[0085] The pot cover 100 is driven to move up and down so that the pot cover 100 is lowered and fastened with the pot. That is, when the pot cover 100 is raised, it can be raised slightly higher. When it rotates to a horizontal state, the bottom surface of the pot cover 100 is higher than the opening of most pots. Then, the pot cover 100 is fastened with the pot by lowering the pot cover 100 to adapt to pots of different heights. Among them, an indirect sensor can be provided on the stirring blade 130 to detect the distance between the stirring blade 130 and the bottom of the pot, so as to determine whether the pot cover 100 can be fastened.

[0086] Furthermore, the method further includes a step between the steps of "receiving a start signal" and "driving the pot cover 100 to move up and down so that the pot cover 100 rises to above the through hole 310 of the table 300": detecting whether there is an obstacle above the panel 320, and using an image acquisition mechanism to acquire an image above the panel 320, analyzing the image to determine whether there is an obstacle. When there is an obstacle, the panel 320 is not opened. When there is no obstacle, the panel 320 is opened.
