Description

Technical Field

[0001] The utility model relates to the technical field of cooking utensils (such as pots), in particular to a cooking utensil with a stirring function. Background Art

[0002] As a popcorn machine which is a special cooking utensil for making popcorn, there are old-fashioned hand-cranked popcorn machines, electric popcorn machines, single-pot popcorn machines, and double-pot popcorn machines; with the improvement of living standards, people have an increasing demand for small and easy-to-operate food processing equipment suitable for families.

[0003] The biggest problem with popcorn machines is that the grains or corn kernels and other processing materials in contact with the bottom of the pot are most likely to burst because they are heated the most, while the processing materials on the upper layer are not easily burst due to less heat, and once the materials on the upper layer burst, the materials at the bottom of the pot are burned, and moreover, since seasonings such as oil, sugar, and salt are added during the processing, and these seasonings also harden during the heating process, resulting in the processing materials sticking to the inner surface of the pot.

[0004] To solve these problems, a Chinese utility model patent (CN 220936635 U) discloses a popcorn machine, including a frying pan, a closed cover is arranged above the frying pan, a planetary gear drive disc is fixed on the top of the closed cover, a motor is arranged on the top of the planetary gear drive disc, an output end of the motor is connected to the planetary gear drive disc, a connecting rod is arranged below the closed cover, an upper end of the connecting rod is connected to the planetary gear drive disc, a lower end of the connecting rod extends into the inner side of the frying pan, and a frying plate is detachably fixed at the bottom of the connecting rod.

[0005] This technical solution limits the frying pan, lacks universality, and cannot well turn up the processing materials at the bottom of the frying pan; moreover, using a motor as the drive is not easy to control, and the motor wires will affect the processing of the frying pan on the gas stove.

[0006] A US patent application (US20230309588A1) discloses a corn popcorn machine with a stirrer, including a pot, which includes one or more inner surfaces defining the inner volume of the pot; a lid assembly, the lid assembly includes a lid, the lid is arranged to cooperate with the pot; a crank, the crank is coupled to the lid and arranged to rotate relative to the lid; and a connecting rod, the connecting rod is coupled to the crank and arranged to rotate together with the crank; a stirrer assembly, which is arranged to be positioned within the inner volume of the pot and releasably engage a connecting member when the lid is in cooperation with the pot.

[0007] This solution is more suitable for home use. However, in order to fix the stirrer, a protrusion is provided at the bottom of the pot. To cooperate with the protrusion, the stirrer is provided with through holes at the blades, and the stirrer is installed on the protrusion through the through holes. This technical solution has special requirements for the pot, resulting in too high costs. Moreover, the ring structure of the stirrer is complex and the installation is troublesome. When stirring, the ring structure of the stirrer will rub against the inner surface of the pot, making it relatively laborious. Summary of the Invention

Detailed implementation manner

[0034] The following further describes the present utility model with reference to the accompanying drawings. The accompanying drawings are only for illustrative purposes and should not be construed as a limitation of this patent.

[0035] For a more concise description of this embodiment, some components that are well known to those skilled in the art but not relevant to the main content of this creation will be omitted in the drawings or description. Additionally, for ease of expression, some components in the drawings will be omitted, enlarged, or reduced, but this does not represent the actual size or entire structure of the product.

[0036] The present utility model discloses a cooking utensil with a stirring function, such as Figures 1-5 shown, which includes a pot body 1 and a lid body 2; a stirrer 9 and a stirrer drive mechanism are also provided.

[0037] As Figure 1 shown, the stirrer drive mechanism includes an operating member, a rack 4, and a drive shaft 5. An installation cavity 21 is provided on the upper surface of the lid body 2. The rack 4 is arranged in the installation cavity 21. The operating member is connected to the rack 4 and controls the reciprocating movement of the rack 4 in the installation cavity 21; preferably, the operating member includes a handle 3 and a push rod 33. The handle 3 includes a fixed end 31 and a free end 32. The fixed end 31 of the handle 3 is rotatably connected to one end of the installation cavity 21. Operating the free end 32 of the handle 3 causes the handle 3 to rotate around its fixed end 31 so as to rotate out of or be stored in the installation cavity 21; one end of the push rod 33 is connected to the handle 3, and the other end is connected to the rack 4; the handle 3, the push rod 33, and the rack 4 are connected in a Z - shape.

[0038] As Figure 5 shown, when the free end 32 of the handle 3 is lifted upward, the handle 3 drives the push rod 33 to rotate out of the installation cavity 21, and the push rod 33 pulls the rack 4 to move in the installation cavity 21 towards the fixed end 31 of the handle 3.

[0039] As Figure 4 shown, when the free end 32 of the handle 3 is pressed down, the handle 3 is pressed into the installation cavity 21, and the push rod 33 pushes the rack 4 to move in the installation cavity 21 towards the free end 32 of the handle 3.

[0040] Preferably, considering the ease of operation, one end of the push rod 33 is connected between the fixed end 31 and the free end 32 of the handle 3, and the other end of the push rod 33 is connected to one end of the rack 4 far from the fixed end 31 of the handle 3, that is, the end adjacent to the free end 32 of the handle 3.

[0041] Further, a return spring 23 is provided at the fixed end 31 of the handle 3. After the handle 3 is pressed into the installation cavity 21 and then released, the handle 3 can rotate out of the installation cavity 21 under the action of the return spring 23, which is convenient for hand-held operation. Correspondingly, when not in use, the handle 3 should be stored in the installation cavity 21. In order to prevent the handle 3 from popping out of the installation cavity 21 under the action of the return spring 23, a storage lock 22 for the handle 3 is provided at the position corresponding to the free end 32 of the handle 3 in the installation cavity 21.

[0042] As Figures 1-3 shown, the drive shaft 5 includes a gear shaft 51 at the upper part and a connecting shaft 52 at the lower part; an installation hole is provided in the installation cavity 21, and the drive shaft 5 is arranged in the installation hole. The gear shaft 51 at its upper part meshes with the rack 4. When the handle 3 drives the rack 4 to move, the rack 4 also drives the drive shaft 5 to rotate through the gear shaft 51; the connecting shaft 52 at the lower part of the drive shaft 5 protrudes from the lower surface of the cover body 2.

[0043] The agitator drive mechanism further includes an agitator connection component, and the agitator 9 is detachably connected to the agitator connection component; the drive shaft 5 drives the agitator 9 to rotate through the agitator connection component.

[0044] As Figure 2 、 Figure 3 shown, the agitator connection component is a ratchet mechanism, including a ratchet 8, a pawl 7 and a rotary fixing piece 6; a through hole is provided in the center of the rotary fixing piece 6, and the rotary fixing piece 6 is sleeved on the connecting shaft 52 at the lower part of the drive shaft 5 through the through hole. The pawl 7 is movably arranged at both ends of the rotary fixing piece 6, and the ratchet 8 is sleeved on the connecting shaft 52 and is located below the rotary fixing piece 6.

[0045] As Figure 3 shown, the ratchet 8 is in the shape of a cylindrical body with an open upper end. The tooth grooves of the ratchet 8 are arranged on the inner wall of the cylinder body. The rotary fixing piece 6 and the pawl 7 are both installed in the cylinder body of the ratchet 8, and the ratchet 8 and the pawl 7 are in an internal meshing relationship. When the drive shaft 5 rotates in one direction (such as the clockwise direction), it drives the rotary fixing piece 6 to rotate. The pawl 7 opens towards the inner wall of the ratchet 8 under the action of the centrifugal force generated by the rotation of the rotary fixing piece 6 and inserts into the tooth grooves of the ratchet 8, driving the ratchet 8 to rotate; when the drive shaft 5 rotates in the opposite direction (such as the counterclockwise direction), the pawl 7 slides over the tooth grooves of the ratchet 8 and the ratchet 8 does not rotate. Therefore, the ratchet mechanism can ensure that the agitator 9 rotates only in one direction.

[0046] The stirrer 9 includes a clamping portion 91, a connecting rod 92, and a stirring member; a clamping interface 81 is provided on the outer wall of the ratchet wheel 8; the stirrer 9 is detachably connected to the clamping interface 81 of the ratchet wheel 8 through the clamping portion 91.

[0047] The stirring member includes an intermediate member 94 and at least two blades 93 provided on the intermediate member 94. The blades 93 are symmetrically arranged with the intermediate member 94 as the center, and the intermediate member 94 is connected to the connecting rod 92.

[0048] The blade 93 has a guiding surface, and the guiding surface forms an angle less than 90° with the bottom surface of the pot body 1.

[0049] As Figure 4 shown, press the free end 32 of the handle 3, press the handle 3 into the installation cavity 21, and the push rod 33 pushes the rack 4 to move in the installation cavity 21 in the direction of the free end 32 of the handle 3. The rack 4 drives the gear shaft 51 to rotate clockwise, thereby driving the rotating fixing piece 6 to rotate clockwise. The pawl 7 is inserted into the tooth groove of the ratchet wheel 8, driving the ratchet wheel 8 to rotate clockwise, thereby driving the stirrer 9 to rotate clockwise. The blade 93 rotates with the stirrer 9, and the guiding surface of the blade 93 stirs up the processing material in the pot body 1, enabling the processing material in the pot body 1 to be evenly heated and preventing the processing material from gathering at the bottom of the pot and causing burning and sticking.

[0050] As Figure 5 shown, lift the free end 32 of the handle 3 upward. The handle 3 drives the push rod 33 to rotate out of the installation cavity 21. The push rod 33 pulls the rack 4 to move in the installation cavity 21 in the direction of the fixed end 31 of the handle 3. The rack 4 drives the gear shaft 51 to rotate counterclockwise, thereby driving the rotating fixing piece 6 to rotate counterclockwise. The pawl 7 slides over the tooth groove of the ratchet wheel 8, and the ratchet wheel 8 does not rotate, and the stirrer 9 does not rotate.

[0051] Press the handle 3 again, and the stirrer 9 rotates again. By pressing and lifting once, using the one-way rotation of the ratchet wheel 8, it is ensured that the stirrer 9 rotates in one direction. Applied to popcorn, the stirrer 9 rotates in one direction, which can make the popcorn fully burst and not stick to the bottom.

[0052] The stirrer 9 of the present utility model is detachable. A clamping interface 81 is provided on the outer wall of the ratchet wheel 8, and different types of stirrers 9 can be installed. The present utility model can be used not only for popcorn but also for stir-frying, beating egg liquid, etc.

[0053] The above is only the preferred embodiment of the present utility model and is not used to limit the implementation scope of the present utility model. That is, all equivalent changes and modifications made according to the content of the patent application scope of the present utility model should fall within the technical scope of the present utility model.
