Description

Technical Field

[0001] This utility model relates to the field of kitchen appliances, and in particular to a cooking pot. Background Technology

[0002] The bottom of the pot in existing stir-fry machines is generally characterized by a large flat bottom with rounded edges, or a large curved bottom. The blade assembly is usually a single stirring blade with forked or stepped blades. When the stirring blade rotates, food tends to stick to the side wall of the pot and rotate with it, resulting in uneven heating and poor stir-frying effect. With a large curved bottom, food tends to accumulate at the blade shaft, and when the quantity is large, it cannot be stirred properly, resulting in uneven heating and unsatisfactory cooking results.

[0003] The existing stepped blades of the blade assembly are generally fixed on the same shaft, which results in the same rotation speed, and still has defects in the stirring and stir-frying effect of food. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects in the prior art where food sticks to the wall and rotates in the cooking pot, resulting in poor stirring effect and uneven heating, and to provide a cooking pot.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A cooking pot is provided, comprising a pot body and a stirring blade assembly. The pot body has a stepped structure, including a bottom portion and an expanding portion, the inner diameter of which is larger than the inner diameter of the bottom portion. The stirring blade assembly includes a lower blade and an upper blade, the lower blade being disposed in the bottom portion and the upper blade being disposed in the expanding portion. The upper and lower blades extend from the central axis of the pot body to the inner wall of the pot body and are in contact with the inner wall of the pot body. The upper and lower blades rotate relative to the pot body.

[0007] In this design, a stepped pot body is used, featuring an expanded section with an inner diameter larger than the bottom. The lower blades of the stirring blade assembly are located at the bottom, stirring the food into the expanded section during rotation. Meanwhile, the upper blades of the stirring blade assembly are located in the expanded section, where the food is stirred back to the lower section. This cycle repeats, achieving layered stirring, ensuring the food is thoroughly cooked and heated evenly. The stirring blade assembly rotates relative to the pot body, and the blades adhere closely to the inner wall of the pot, preventing uneven heating or insufficient stirring of the food.

[0008] Preferably, the stirring blade assembly further includes a connecting component, which rotates relative to the pot body, with one end of the upper blade and one end of the lower blade respectively connected to the side wall of the connecting component.

[0009] In this solution, a connecting component is provided to connect the upper and lower blades to the pot body. Since the connecting component can rotate relative to the pot body, the upper and lower blades connected to the connecting component can also rotate relative to the pot body. During use, they are used to stir and stir the food inside the pot.

[0010] Preferably, the connecting assembly includes an upper connector and a lower connector, one end of the upper blade is connected to the upper connector, one end of the lower blade is connected to the lower connector, and the upper connector and the lower connector are configured for speed change transmission.

[0011] In this design, by setting an upper connector and a lower connector, the upper and lower blades are respectively set on two different connectors. At the same time, the upper and lower connectors are equipped with variable speed transmission, so that the upper and lower blades have different rotation speeds, and the food is stirred in layers in the pot.

[0012] Preferably, the upper connector is provided with a first connecting tooth, and the lower connector is provided with a second connecting tooth. The first connecting tooth and the second connecting tooth cooperate with each other, and the gear ratios of the first connecting tooth and the second connecting tooth are different, so that the rotational speeds of the upper connector and the lower connector are different.

[0013] In this solution, connecting teeth with different tooth densities are set on the upper and lower connecting parts, and the gear ratio is set according to the actual use requirements. When the motor drives the connecting components, different speeds can be generated between the upper and lower connecting parts. The connecting teeth are set for the speed transmission of the connecting components to realize different speeds of the stirring blade assembly. The structure is simple and the effect is good.

[0014] Preferably, the connecting assembly includes a bushing, with a portion of the upper connector and a portion of the lower connector extending into the bushing and connected inside the bushing.

[0015] In this solution, a bushing is installed at the connection between the upper and lower connectors to effectively protect the connection and prevent misalignment or disengagement during the speed change process, thus avoiding transmission failure or damage to parts.

[0016] Preferably, the pot body also includes a pressure detection device, a motor, and a control unit. The pressure detection device is connected to the expansion section and is used to generate an electrical signal. The pressure detection device, motor, and control unit are electrically connected.

[0017] In this solution, a pressure detection device is installed in the expansion section to collect the pressure on the pot body when the food rotates and squeezes the side wall of the pot body, and generates an electrical signal that is transmitted to the control unit. The control unit controls the current of the motor according to the electrical signal, and generates different stirring blade speeds according to different currents, so that the optimal stir-frying speed can be matched according to different weights of food.

[0018] Preferably, the pot body further includes an outer shell, which is fitted over the outside of the pot body, and the pressure detection device is sandwiched between the pot body and the outer shell.

[0019] In this solution, by setting the pressure detection device in the outer shell, it is not only fixed to the outer wall of the pot, but also isolated from the outside, which protects the pressure detection device and extends its service life. The outer shell design is simple and fits the shape of the pot, so it will not make the cooking pot too big.

[0020] Preferably, the pressure detection device is a piezoelectric ceramic sheet, which has an annular sheet structure and is attached to the outer wall of the expansion portion.

[0021] In this solution, a piezoelectric ceramic sheet is selected as the pressure detection device. It has a simple structure, is lightweight and small in size, and will not cause the cooking pot to become too heavy. Moreover, the structure of the piezoelectric ceramic sheet can better fit the expansion part. The ring structure can make the piezoelectric ceramic sheet cover the outer wall of the entire expansion part, making the detection more accurate and improving the reliability.

[0022] Preferably, the motor is connected to the stirring blade assembly.

[0023] In this solution, the motor is electrically connected to the pressure detection device. By receiving different electrical signals generated by the pressure detection device, different currents are generated to adjust the motor speed, thereby driving the stirring blade assembly to rotate at different speeds and achieve better cooking results.

[0024] Preferably, the bottom edge of the lower blade is fitted to the inner bottom of the pot body, and the side edge of the lower blade is fitted to the inner wall of the bottom part; the side edge of the upper blade is fitted to the inner wall of the expanded part.

[0025] In this design, the blades fit snugly against the inner wall of the pot, preventing some food from being insufficiently stirred. By having the stirring blades adhere closely to the inner wall of the pot and thoroughly stir-fry the food, even heating of the food is ensured, thus improving the uniformity of heating in the cooking pot.

[0026] The significant advantages of this invention are as follows: The stepped pot body has an expanded portion with an inner diameter larger than the bottom. The lower blades of the stirring blade assembly are located at the bottom, stirring the food into the expanded portion during rotation. Meanwhile, the upper blades of the stirring blade assembly are located in the expanded portion, where the food is stirred to the lower layer. This cycle repeats, achieving layered stirring, ensuring the food is thoroughly cooked and heated evenly. The stirring blade assembly rotates relative to the pot body, and the blades are in close contact with the inner wall of the pot, preventing uneven heating or insufficient stirring of the food.

[0049] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0050] This utility model provides a cooking pot, such as Figure 1-4As shown, the apparatus includes a pot body 1 and a stirring blade assembly 2. The pot body 1 has a stepped structure, including a bottom portion 11 and an expansion portion 12. The inner diameter of the expansion portion 12 is larger than the inner diameter of the bottom portion 11. The stirring blade assembly 2 includes a lower blade 22 and an upper blade 21. The lower blade 22 is disposed in the bottom portion 11, and the upper blade 21 is disposed in the expansion portion 12. The upper blade 21 and the lower blade 22 extend from the central axis of the pot body 1 to the inner wall of the pot body 1 and are in contact with the inner wall of the pot body 1. The upper blade 21 and the lower blade 22 rotate relative to the pot body 1.

[0051] The pot body 1 is designed with a stepped structure, featuring an expanded portion 12 with an inner diameter larger than the bottom portion 11. The lower blade 22 of the stirring blade assembly 2 is located at the bottom portion 11, and during rotation, it stirs the food into the expanded portion 12 of the pot body 1. The upper blade 21 of the stirring blade assembly 2 is located at the expanded portion 12, and the food is then stirred to the lower layer by the upper blade 21. This cycle repeats, achieving layered stirring, which ensures that the food is thoroughly stir-fried within the pot body 1 and its surface is evenly heated. The stirring blade assembly 2 rotates relative to the pot body 1, and the blades are in close contact with the inner wall of the pot body 1, preventing uneven heating or insufficient stirring of the food.

[0052] Specifically, in this embodiment, such as Figure 1-2 As shown, the bottom part 11 and the expansion part 12 of the pot body 1 are designed with stepped arcs to form an upper and lower stepped pot body 1. The upper blade 21 and the lower blade 22 of the stirring blade assembly 2 each have an independent blade for stirring food.

[0053] In this embodiment, the stirring blade assembly 2 further includes a connecting component 3. The connecting component 3 rotates relative to the pot body 1, and one end of the upper blade 21 and one end of the lower blade 22 are respectively connected to the side wall of the connecting component 3. By setting the connecting component 3, the upper blade 21 and the lower blade 22 are connected to the pot body 1. Since the connecting component 3 can rotate relative to the pot body 1, the upper blade 21 and the lower blade 22 connected to the connecting component 3 can also rotate relative to the pot body 1. During use, they are used to stir and stir the food in the pot body 1. In other possible embodiments, other components can also be set, as long as they can rotate relative to the pot body 1 and are connected to the upper blade 21 or the lower blade 22.

[0054] Furthermore, the connecting assembly 3 includes an upper connector 31 and a lower connector 32. One end of the upper blade 21 is connected to the upper connector 31, and one end of the lower blade 22 is connected to the lower connector 32. The upper connector 31 and the lower connector 32 are configured for variable speed transmission. By setting the upper connector 31 and the lower connector 32, the upper blade 21 and the lower blade 22 are respectively mounted on two different connectors. Simultaneously, the variable speed transmission between the upper connector 31 and the lower connector 32 allows the upper blade 21 and the lower blade 22 to rotate at different speeds, enabling the food to be stirred in layers within the pot body 1. In other possible embodiments, the connecting assembly 3 can be configured with other structures, as long as it satisfies the variable speed rotation of the upper blade 21 and the lower blade 22.

[0055] The upper connecting member 31 is provided with a first connecting tooth 311, and the lower connecting member 32 is provided with a second connecting tooth 322. The first connecting tooth 311 and the second connecting tooth 322 cooperate with each other. The gear ratios of the first connecting tooth 311 and the second connecting tooth 322 are different, resulting in different rotational speeds for the upper connecting member 31 and the lower connecting member 32. By providing connecting teeth with different tooth densities on the upper connecting member 31 and the lower connecting member 32, and setting the gear ratio according to actual usage requirements, different rotational speeds can be achieved when the motor 6 drives the connecting assembly 3. The connecting teeth are used for the speed change transmission of the connecting assembly 3, realizing different rotational speeds of the stirring blade assembly 2. The structure is simple and effective.

[0056] Specifically, in this embodiment, such as Figure 3 As shown, the first connecting tooth 311 and the second connecting tooth 322 have different numbers of gears, and the gear ratio between the first connecting tooth 311 and the second connecting tooth 322 is 2:1. During rotation, only a portion of the connecting teeth of the first connecting tooth 311 and the second connecting tooth 322 mesh. The different number of gears and the partial meshing of the connecting teeth achieve the effect of variable speed transmission. Because the upper connecting member 31 and the lower connecting member 32 are configured for variable speed transmission, the speed ratio between the upper blade 21 and the lower blade 22 is 2:1. In other possible embodiments, variable speed transmission between the upper connecting member 31 and the lower connecting member 32 can be achieved by setting other structures, or different speed ratios can be set according to usage requirements, as long as the speeds of the upper blade 21 and the lower blade 22 are different.

[0057] Furthermore, the connecting assembly 3 includes a bushing 33, with a portion of the upper connecting member 31 and a portion of the lower connecting member 32 extending into the bushing 33 and connected inside the bushing 33. Providing the bushing 33 at the connection between the upper connecting member 31 and the lower connecting member 32 effectively protects the connection, preventing misalignment or disengagement during speed change, and avoiding transmission failure or component damage. In other possible embodiments, other components can be used instead of the bushing 33, as long as they can protect the connection between the upper connecting member 31 and the lower connecting member 32.

[0058] In this embodiment, the pot body 1 also includes a pressure detection device, a motor 6, and a control unit. The pressure detection device is connected to the expansion portion 12 and is used to generate an electrical signal. The pressure detection device, motor 6, and control unit are electrically connected. The pressure detection device in the expansion portion 12 collects the pressure exerted on the pot body 1 when food rotates and squeezes the side wall of the pot body 1, and generates an electrical signal that is transmitted to the control unit. The control unit controls the current of the motor 6 based on the electrical signal, generating different stirring blade speeds according to different currents, thus matching the optimal stir-frying speed to different weights of food.

[0059] The pot body 1 also includes an outer shell 4, which is fitted over the outside of the pot body 1. A pressure detection device is clamped between the pot body 1 and the outer shell 4. By clamping the pressure detection device with the outer shell 4, it is not only fixed to the outer wall of the pot body 1, but also isolated from the outside, protecting the pressure detection device and extending its service life. The outer shell 4 has a simple design and fits the shape of the pot body 1, preventing the cooking pot from becoming excessively large. In other possible embodiments, other structures can be used instead of the outer shell 4, as long as they allow the pressure detection device to be fixed to the expansion portion 12.

[0060] Specifically, such as Figure 4 As shown, the pressure detection device is a piezoelectric ceramic sheet 5, which has a ring-shaped structure and is fitted to the outer wall of the expansion portion 12. Using the piezoelectric ceramic sheet 5 as the pressure detection device results in a simple structure, light weight, and small size, preventing the cooking pot from becoming excessively heavy. Furthermore, the structure of the piezoelectric ceramic sheet 5 allows for better fit to the expansion portion 12, and the ring-shaped structure ensures that the piezoelectric ceramic sheet 5 covers the entire outer wall of the expansion portion 12, making the detection more accurate and improving reliability. In other possible embodiments, other components can be used for the pressure detection device, as long as they meet the detection requirements.

[0061] Furthermore, motor 6 is connected to the mixing blade assembly 2. Motor 6 is electrically connected to a pressure detection device. By receiving different electrical signals generated by the pressure detection device, different currents are generated to adjust the speed of motor 6, thereby driving the mixing blade assembly 2 to rotate at varying speeds and achieve better cooking results.

[0062] Specifically, in this embodiment, the motor 6 is connected to the stirring blade assembly 2 via a clutch. The clutch includes an upper clutch 61 and a lower clutch 62, wherein the motor 6 is connected to the lower clutch 62, and the upper clutch 61 is detachably connected to the lower clutch 62. The upper clutch 61 is connected to the bottom gear of the stirring blade assembly 2. By setting the clutch, the pot body 1 is separated from the motor 6, facilitating cleaning by the user. In other possible embodiments, other structures can also be used to connect the motor 6 to the stirring blade assembly 2, as long as the motor 6 can control the rotation speed of the stirring blade assembly 2 and is detachably connected to the stirring blade assembly 2.

[0063] In this embodiment, as Figure 1 As shown, the bottom edge of the lower blade 22 is fitted to the inner bottom of the pot body 1, and the side edge of the lower blade 22 is fitted to the inner wall of the bottom part; the side edge of the upper blade 21 is fitted to the inner wall of the expansion part 12. By fitting the blades to the inner wall of the pot body 1, the situation where some food is not fully stirred in the pot body 1 is avoided. The stirring blade assembly 2, closely attached to the inner wall of the pot body 1, thoroughly stirs the food in the pot body 1, ensuring even heating of the food and improving the uniformity of heating in the cooking pot. In other possible embodiments, the upper blade 21 and the lower blade 22 can also be designed with other structures, as long as they do not affect their ability to fully stir the food in the pot body 1.

[0064] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
