[0076] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0077] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0078] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0079] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0080] The present invention aims to provide an electric wok with a novel stirring device, and the stirring device is used to drive the stirring blade to lift at least once relative to the inner wall of the wok within a swing cycle to achieve a more uniform stirring process.

[0081] The wok described above can be a semi-spherical shape, a semi-cylindrical shape, a semi-olive shape or a flat pan;

[0082] The swing cycle refers to that under the action of the stirring drive device, the stirring blade swings from one side of the wok to the other side of the wok, and then swings back from the other side of the wok to this side of the wok. The rising and falling refer to the relative rising and falling of the bottom of the stirring blade with respect to the inner wall of the wok corresponding to the stirring blade.

[0083] The stirring blade is designed according to the structural form of the cookware, such as L-shaped, concave-shaped, U-shaped, semi-circular, 1 / 4 circular arc, etc.

[0084] The sliding drive arm is arranged in an L shape and includes a short arm and a long arm; the long arm is used for sliding connection with the stirring drive device, and the free end of the short arm of the sliding drive arm is connected to the stirring blade. For semi-circular and concave-shaped stirring blades, sliding drive arms can be arranged at one or both ends of the stirring blade; for L-shaped, 1 / 4 circular arc, etc. sliding drive arms, the sliding drive arm is arranged at one end of the stirring blade.

[0085] The stirring drive device is mainly used to provide the driving force for swinging. The swinging can adopt a mechanical conversion device to convert the rotational motion of the motor or the output shaft of the reduction motor into a reciprocating swinging motion; it can also adopt an electric push rod to reciprocally push the shaft handle on one side of the stirring blade shaft to achieve swinging; it can also be achieved by setting limit switches on both sides of the cookware and then controlling the forward and reverse rotation of the reduction motor; that is, when the reduction motor rotates forward, when the stirring blade runs to the limit switch on the left side of the cookware, the reduction motor flips from forward rotation to reverse rotation; thus driving the stirring blade to swing towards the right side of the cookware. When the stirring blade swings to the limit switch on the right side of the cookware, the reduction motor flips from reverse rotation to forward rotation, driving the stirring blade to swing towards the limit switch on the left side of the cookware, until it swings to the limit switch on the left side of the cookware, and the reduction motor flips from forward rotation to reverse rotation again, and so on. For semi-circular or concave-shaped stirring blades, the stirring drive device can be arranged on one side of the stirring blade, or one can be arranged on each side of the stirring blade. It is also possible to arrange a stirring drive device on one side of the stirring blade and a sliding support seat on the other side of the stirring blade, etc.

[0086] The so-called sliding connection means that a sliding sleeve is arranged on the output shaft of the stirring drive device, and a square (or other polygon) guiding sliding hole is arranged on the sliding sleeve; the sliding drive arm with a square cross-section (matched with the cross-section of the sliding hole) is inserted into the sliding sleeve, so that the swinging drive of the stirring blade can be realized, and the sliding connection between the sliding drive arm and the sliding sleeve can also be realized. At the same time, the square guiding sliding hole and the square sliding drive arm cooperate to prevent the sliding drive arm from rotating relative to the sliding sleeve; for the situation where stirring drive devices are arranged on both sides of the stirring blade, or for the situation where a stirring drive device is arranged on one side of the stirring blade and a sliding support seat is arranged on the other side, the two sliding drive arms are both slidably arranged in the sliding sleeve to play a guiding role. At this time, the sliding hole and the sliding drive arm can also be circular. As a deformation of the above sliding connection, a sliding groove can also be arranged on the sliding drive arm, and the output shaft of the stirring drive device is an insertion piece adapted to the sliding groove; inserting the insertion piece type output shaft into the sliding groove on the sliding drive arm can also produce a similar effect. The following content is described by taking the sliding sleeve as an example.

[0087] A sliding drive device is used to drive a sliding drive arm to slide relative to a sliding sleeve, thereby driving the stirring blade to lift at least once relative to the inner wall of the cooking pot within a swinging cycle. It can be electric or mechanical and can be set according to needs. For example, in an electric drive mode, an electric push rod can be arranged on one side of the sliding sleeve, and the free end of the electric push rod is arranged on the sliding drive arm. By driving the reciprocating motion of the electric push rod, the reciprocating motion of the sliding drive arm relative to the sliding sleeve can be realized, but this method has a higher cost. Another example is a mechanical drive mode. A roller is arranged on one side of the free end of the sliding drive arm; a guide rail groove is arranged on one side of the sliding drive arm; during the swinging process of the sliding drive arm, the roller slides along the guide rail groove. In this way, by changing the shape of the guide rail groove, the movement track of the sliding drive arm can be changed. Another mechanical drive mode is that a guide rail head is arranged at the free end of the sliding drive arm, and the guide rail head can be a ball or a roller; a guide rail is arranged corresponding to the guide rail head; during the swinging process of the sliding drive arm, the guide rail head slides along the guide rail. In this way, by changing the shape of the guide rail, the movement track of the sliding drive arm can also be changed.

[0088] Embodiment 1

[0089] Figure 1 The structural schematic diagram of this embodiment is shown in the figure. It includes a housing 1, a cooking pot 2 is arranged in the housing, and an arc-shaped stirring blade 3 is arranged in the cooking pot; a stirring drive device 4 is arranged on one side of the cooking pot corresponding to the stirring blade; a sliding hole is radially arranged on the drive shaft of the drive device;

[0090] Sliding drive arms 5 are arranged at both ends of the arc-shaped stirring blade. The sliding drive arms are in an inverted L shape, and the free end of the short arm is connected to the arc-shaped stirring blade; the long arm part is slidably connected in the sliding hole of the drive shaft, and the long arm is arranged in the same direction as the stirring blade; the stirring drive device drives the sliding drive arms to swing through the drive shaft, and then drives the stirring blade to swing repeatedly in the cooking pot to achieve swinging stirring.

[0091] A drive head is arranged at the free end of the long arm of the sliding drive arm. In this embodiment, the drive head is a roller outside the sliding drive arm.

[0092] An inverted U-shaped guide rail groove is arranged in the housing corresponding to the free end of the long arm. The guide rail groove can be obtained by sheet metal of a metal plate or made by means such as grooving on a thick plate material; the shape of the guide rail groove in the length direction is the swinging track of the roller; it can be designed according to needs; during the swinging process of the stirring shaft, the roller slides in the guide rail groove along the guide rail groove. Figure 2 Shown as Figure 1 The side view of the part of the guide rail groove and the sliding drive arm in the figure; as shown in the figure, the guide rail groove is a horizontally arranged straight line; Figure 3 For Figure 2Schematic diagrams of the swing of the sliding drive arm at different positions. As shown in the figure, when the roller reciprocates in the guide rail groove, the sliding drive arm slides relative to the stirring shaft. That is, when the sliding drive arm swings to the middle of the guide rail groove, it is in a vertical state. At this time, the sliding drive arm drives the stirring blade to the highest position, and the lower end of the stirring blade is the farthest from the bottom of the cookware. When the sliding drive arm swings to both ends of the guide rail groove, it is in an inclined state. At this time, the sliding drive arm drives the stirring blade to the lowest position, and the lower end of the stirring blade is the closest to the bottom of the cookware.

[0093] Embodiment 2

[0094] Figures 4 to 6 is Figure 1 A variation of the shown embodiment, which is different in that the directions of the sliding drive device and the sliding drive arm and the stirring blade are opposite. As shown in the figure, sliding drive arms 5 are provided upward at both ends of the arc-shaped stirring blade. The sliding drive arm is L-shaped, and the free end of its short arm is connected to the arc-shaped stirring blade. The long arm part is slidably connected in the sliding hole of the drive shaft. The stirring drive device drives the sliding drive arm to swing through the drive shaft, and then drives the stirring blade to swing repeatedly in the cookware to achieve swinging stirring.

[0095] A slide U-shaped guide rail groove is provided on the stirring drive device in the housing, and the roller slides along the guide rail groove in the guide rail groove. Figure 5 Shown as Figure 4 The side view of the part of the guide rail groove and the sliding drive arm in Figure 6 is Figure 4 Schematic diagrams of the swing of the sliding drive arm at different positions. As shown in the figure, when the roller reciprocates in the guide rail groove, the sliding drive arm slides relative to the stirring shaft. That is, when the sliding drive arm swings to the middle of the guide rail groove, it is in a vertical state. At this time, the sliding drive arm drives the stirring blade to the lowest position, and the lower end of the stirring blade is the closest to the bottom of the cookware. When the sliding drive arm swings to both ends of the guide rail groove, it is in an inclined state. At this time, the sliding drive arm drives the stirring blade to the highest position, and the lower end of the stirring blade is the farthest from the bottom of the cookware.

[0096] Embodiment 3

[0097] As an improvement of the above embodiment, as Figures 9 to 11 shown, a positioning member such as a through bolt, a nut, etc. is provided at the lower section of the long arm. A return spring is sleeved on the long arm between the positioning member and the drive shaft. In this way, the guide rail groove can be changed to a track; the guide rail head is made to run along the track by the action of the return spring.

[0098] As Figure 11 shown, the return spring can be a compression spring, as shown in the above figure; it can also be a tension spring, as shown in the following figure. It can be designed according to needs.

[0099] Example 4

[0100] As a further improvement of the above embodiments, when the cookware is semi-spherical, it further includes a cookware rotation driving device for driving the cookware to rotate during the cooking process to achieve a more complex stirring process.

[0101] The cookware rotation driving device can be designed as needed; for example, a rotating base can be provided at the bottom of the cookware, and the rotating base is driven by a motor to rotate to drive the cookware to rotate; or a ring-shaped rotating support can be provided at the rim of the cookware, and the cookware is placed inside the ring-shaped rotating support, etc.

[0102] During the manual cooking process, usually a spatula is slid down along the bottom of the pan from one side of the pan, and when sliding down near the bottom of the pan, the spatula is turned up to complete a stirring (turning); then, this action is repeated from the other side of the pan to complete a new stirring (turning), and so on until it is cooked. In order to better simulate the way of manual cooking, the present invention further adds a movable track on the basis of the above track; the form of the movable track can be strip-shaped or wedge-shaped, and further description will be made in combination with the embodiments.

[0103] Example 5

[0104] As Figure 7 and Figures 12 to 20 shown, the above-mentioned sliding driving device includes: a semi-circular base track; two block-shaped (wedge-shaped) movable tracks 7 are symmetrically hinged above the semi-circular base track through a hinge shaft 9; the movable track can be designed as a single wedge or a double wedge as needed, as shown in the figure, the movable track is a double wedge; its outer contour includes a driving surface on the inner side and an outer side surface adapted to the semi-circular base track; a gap adapted to the driving roller is formed between the outer side surface and the semi-circular base track; for a single wedge, the inner driving surface includes a guiding section located below and a track section located above the guiding section; for a double wedge, the inner driving surface at least includes a lower guiding section, a track section and an upper guiding section from bottom; wherein, the lower guiding section of the inner driving surface and the lower section of the outer side surface together form the lower wedge part at the lower end of the movable track; the upper guiding section of the inner driving surface and the upper section of the outer side surface together form the upper wedge part at the lower end of the movable track; the upper wedge part and the lower wedge part are mainly for facilitating the roller to roll into and out of the movable track.

[0105] In order to ensure that the outer side surface at the lower end of the movable track presses downward on the track, two methods can be adopted:

[0106] 1) The hinge point of the movable track is located above the center of gravity of the movable track, resulting in an eccentric setting of the movable track, and under the action of gravity, its outer side surface presses downward on the guiding track.

[0107] 2) A resilient element is provided, and under the action of the resilient element, the outer side surface of the wedge portion of the movable track abuts against the guiding track. For example: a torsion spring is provided at the hinge shaft, and under the action of the torsion spring, the outer side surface of the wedge portion of the movable track abuts against the guiding track; or a tension spring or a rubber band is provided between the movable track and the guiding track to make the outer side surface of the wedge portion of the movable track abut against the guiding track.

[0108] When the roller on the sliding drive arm swings from the track to the movable track here, the roller rolls upward along the lower guiding section of the movable track onto the movable track and further runs upward along the track section of the movable track; the track section of the movable track can be designed as a required curve section according to needs; when the roller on the sliding drive arm swings further upward beyond the hinge point, the movable track will deflect accordingly; when the roller on the sliding drive arm swings even further upward beyond the movable track, the sliding drive arm abuts against the semi-circular base track under the action of the spring; the movable track loses the pressure of the sliding drive arm and the upper end of the outer side surface abuts against the track under the action of gravity; at this time, the sliding drive arm reaches the upper dead center on this side, the running track of the sliding drive arm flips and starts to run downward; since there is a gap adapted to the driving roller formed between the outer side surface and the semi-circular base track; so the roller swings downward along the track and pushes open the movable track when passing through the movable track, continues to swing along the track to the other side, and then runs to the movable track on the other side; similarly, the roller rolls upward along the lower guiding section of the movable track on the other side onto the movable track and further runs upward along the track section of the movable track; when the roller on the sliding drive arm swings upward beyond the movable track, the sliding drive arm abuts against the other side of the semi-circular base track under the action of the spring; the movable track on the other side loses the pressure of the sliding drive arm and the upper end of the outer side surface abuts against the track under the action of gravity; at this time, the sliding drive arm reaches the upper dead center on this side, the running track of the sliding drive arm flips and starts to run downward; since there is a gap adapted to the driving roller formed between the outer side surface and the semi-circular base track; so the roller swings downward along the track and pushes open the movable track when passing through the movable track, continues to swing along the track, and a figure-eight stirring is completed in a cycle; since when the roller is on the semi-circular base track, the stirring blade is at the lowest position of the cookware, and when walking on the movable track, it runs at a high position. In this way, when a swinging cycle is completed, a four-stage action of high, low, high, and low is formed, thus better imitating the way of manual stir-frying and increasing the uniformity of stirring.

[0109] Embodiment 6

[0110] As a variation of Embodiment 5, only one of the above-mentioned movable tracks can also be used, and in this way, the actions of low, low, high, and low can also be completed. Moreover, when only one movable track is used, it can be arranged at the required position according to needs.

[0111] Embodiment 7

[0112] As a variation of Embodiment 5, the sliding drive device and the sliding drive arm can also be arranged above the stirring shaft in the same form as in Embodiment 2; as Figures 21 to 23 shown, the sliding drive device is arranged above the cookware; the two sliding drive arms are arranged in the opposite direction to the stirring blades; the two movable tracks are arranged above the semi-circular base track, and the inner arc segments of the two movable tracks; the outer side is the track segment; the rollers are slidably arranged on the side of the semi-circular base track far from the cookware, and the return spring on the sliding drive arm is a tension spring for pulling the rollers to always face the center direction of the cookware; the inner sides of the upper ends of the two wedge blocks are pressed against the semi-circular base track under the action of gravity or elastic elements; Figure 21 The figure shows a schematic structural view when the sliding drive arm swings to make the roller roll to the upper guiding section outside the left movable track; Figure 22 The figure shows a schematic structural view when the sliding drive arm swings to make the roller roll to the lower guiding section outside the left movable track; Figure 23 The figure shows a schematic structural view when the sliding drive arm swings to make the roller roll to the arc section inside the left movable track; with further swinging, the sliding drive arm will swing to the right movable track and then repeat the above actions in reverse, and so on.

[0113] In summary, it can be seen that the operation process of this embodiment is similar to that of Embodiment 5 and will not be elaborated here.

[0114] Embodiment 8
