Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

The embodiment discloses a stirring assembly capable of driving stirring action in a spaced mode, a frying machine upper cover comprising the stirring assembly and a frying machine comprising the frying machine upper cover. As shown in figure 1, the cooking machine comprises a pot body 4, a base 5 and a cooking machine upper cover, wherein the pot body 4 is detachably arranged on the base 5, the cooking machine upper cover can be buckled on the pot body 4, and the pot cover 1 of the cooking machine upper cover and the pot body 4 enclose to form a cooking space.

As shown in fig. 2 to 12, the upper cover of the cooker comprises a cooker cover 1 and a stirring assembly, and a power induction member 21 and a stirring rod 22 of the stirring assembly can cling to the inner side surface of the cooker cover 1 under the driving force of a driving device. The stirring assembly comprises a power induction part 21, a stirring rod 22, a stirring base 23 and a driving device, wherein the power induction part 21 is installed in the stirring base 23, the stirring rod 22 is installed on the stirring base 23 and can rotate around an installation shaft, and the power induction part 21 and the driving device are separately arranged on the upper side and the lower side of the pot cover 1. The power sensing member 21 can sense the driving force of the driving device, and is tightly attached to the lower side surface of the pot cover 1 to move under the action of the driving force, and meanwhile, the power sensing member 21 drives the stirring rod 22 to rotate in the circumferential direction and/or move in a linear manner under the action of the driving force of the driving device.

The cooker cover 1 of the upper cover of the cooker does not need to be provided with a through hole for penetrating the rotating shaft, the integrity of the cooker cover 1 is kept, the processing is convenient, the processing cost is low, the integral strength of the cooker cover 1 is high, and the problem that the cooker body is damaged by an under-shaft stirring structure is solved; the stirring component can be conveniently taken down from the cooker cover 1, thereby simplifying the cleaning steps, being convenient to disassemble and assemble and improving the sanitation level of the cooker.

The power induction member 21 is preferably a stirring magnetic member such as a permanent magnet or an electromagnet. The driving device comprises a motor 31 arranged outside the pot cover 1, a driving magnetic member 32, a rotating shaft 33, a sliding block 34, a rotating base 35 and a gear assembly, wherein the gear assembly comprises a driving gear 36, an intermediate gear 37 and a driven gear 38, and a rack 341 is arranged on the sliding block 34. The driving magnetic member 32 is magnetically connected to the stirring magnetic member so that the driving magnetic force of the driving magnetic member 32 can be transmitted to the stirring magnetic member. The driving magnetic member 32 is mounted on a slider 34, and the slider 34 is mounted on a rotating base 35 and can rotate with the rotating base 35 and move relative to the rotating base 35.

The output shaft of the motor 31 is connected to a shaft 33 for transmitting the rotation of the output shaft to the drive means and various structures on the stirring assembly. The rotating shaft 33 is a cylindrical whole, and includes an upper flat column 332, a shoulder 331, a cylinder 334 and a lower flat column 333 in sequence from top to bottom. The driving gear 36 and the driven gear 38 are sleeved on the rotating shaft 33, the driving gear 36 is installed above the shaft shoulder 331, namely, the driving gear 36 is installed on the upper flat column 332, and the driving gear 36 can rotate along with the rotating shaft 33; the driven gear 38 is mounted below the shaft shoulder 331, and the cylindrical first shaft mounting hole 383 in the middle of the driven gear 38 is matched with the cylinder 334, that is, the shaft 33 only limits the driven gear 38, and the driven gear 38 does not rotate along with the shaft 33. The non-circular second shaft mounting hole 352 of the rotating base 35 is sleeved on the lower flat column 333, so that the rotating base 35 can rotate along with the shaft 33, and further drive the stirring rod 22 to rotate circumferentially, as shown by the curve with a double-headed arrow in fig. 2. After the rotating base 35 is installed, a fixing member such as a bolt is sleeved at the end of the lower flat column 333, so that the rotating shaft 33 is prevented from being separated from the rotating base 35.

The intermediate gear 37 is coaxially provided with upper and lower teeth, which are engaged with the driving gear 36 and the driven gear 38, respectively. Specifically, the driven gear 38 includes a full tooth portion 381 and an incomplete tooth portion 382 coaxially disposed, the full tooth portion 381 meshes with the intermediate gear 37, and the incomplete tooth portion 382 meshes with the rack 341. The two layers of teeth on the intermediate gear 37 have different radii, so that the driving gear 36 and the driven gear 38 rotate at different speeds. Because the driven gear 38 does not rotate with the rotating shaft 33 and the rotating speed thereof is different from the rotating speed of the rotating shaft 33 (equal to the rotating speed of the driving gear 36), the driven gear 38 can rotate relative to the rotating base 35 (the rotating base 35 thereof is equal to the rotating speed of the driving gear 36), so as to push the rack 341 engaged therewith to move relative to the rotating base 35, and further drive the stirring rod 22 to move linearly, as shown by the line with the double-headed arrow in fig. 2.

The slider 34 is a ring-shaped structure, the inner wall of the slider 34 extends inward to form a support rim 342, and the bottom surface of the driven gear 38 abuts against the support rim 342. That is, the bottom surface of the incomplete tooth 382 abuts on the support rim 342, and supports the driven gear 38 without affecting the rotation thereof, thereby preventing the driven gear 38 from moving downward along the rotation shaft 33.

Of course, the shaft 33 may have other configurations. For example, a shoulder 331 may be provided between the cylinder 334 and the lower flat column 333, the driven gear 38 being disposed above the shoulder 331, the shoulder 331 being used to prevent the driven gear 38 from moving downward along the rotation shaft 33; a bearing or other structure may be provided between the driven gear 38 and the drive gear 36 to ensure that the driven gear 38 does not rotate with the drive gear 36 due to contact with the drive gear 36.

Two racks 341 are preferably oppositely arranged on the annular sliding block 34, and when the incomplete tooth portion 382 of the driven gear 38 is meshed with the rack 341 on one side, the rack 341 is pushed to move forward, that is, the driving magnetic member 32 is pushed to move forward, and then the stirring rod 22 is driven to move forward by the power induction member 21; when the incomplete tooth portion 382 is disengaged from the rack 341 on the one side and is meshed with the rack 341 on the other opposite side, the rack 341 is pushed to move backwards, that is, the driving magnetic member 32 is pushed to move backwards, and then the stirring rod 22 is driven to move backwards through the power induction member 21, so that the stirring rod 22 continuously reciprocates, and the food to be cooked is fully stirred.

The stirring assembly preferably includes two stirring rods 22 having different inclination angles. When the stirring assembly rotates in the circumferential direction, because of different inclination angles, the two stirring rods 22 respectively stir the food materials at the positions close to the center of the pot body 4 and the food materials at the positions far away from the center of the pot body, the situation that the food materials to be cooked are not uniform in cooking is avoided, and the automatic cooking result is better.

The mounting structure between the rotary base 35 and the slider 34 and the mounting structure between the rotary base 35 and the pot cover 1 are not particularly limited, and can be stably mounted without affecting normal use. Preferably, the slide block 34 is provided with a limiting groove 343, the rotating base 35 is provided with a limiting convex rib 354, and the limiting groove 343 is matched with the limiting convex rib 354, so that the slide block 34 can move linearly relative to the rotating base 35. Be provided with the spacing hole 351 of slider of bar on the rotating base 35, install drive magnetic force piece 32 on the slider 34 bottom surface and stretch into the spacing hole 351 of slider, can assist restriction slider 34 can not be rotatory for rotating base 35, can reduce again and power response piece 21 between the distance, improved the magnetic attraction of drive magnetic force piece 32 to power response piece 21. The rotating base 35 is further provided with a ball 353 to reduce the resistance of the rotating base 35 when moving along the outer surface of the pot cover 1, so that the rotating base 35 moves more stably and smoothly.

The rotating base 35 is preferably designed to be long and round at both ends, and a round recess 11 is formed on the lid 1. The curvature of both ends of the spin base 35 is the same as that of the edge of the recess 11, so both ends of the spin base 35 can abut on the inner wall of the recess 11. When the rotating base 35 rotates along with the rotating shaft 33, the inner wall of the concave portion 11 can provide certain supporting force for two ends of the rotating base 35, so that the rotating base 35 is prevented from shaking up and down when the rotating base 35 is active, and the rotating base 35 can move more stably.

It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
