Description
Cooking utensil with stirring function TECHNICAL FIELD
[0001] The present application relates to the technical field of cooking utensils (such as pots), and in particular to a cooking utensil with stirring function. BACKGROUND
[0002] As a cooking utensil, the popcorn machine is a special cooking utensil for making popcorn, including old-fashioned hand-operated 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, easy-to-operate food processing equipment suitable for families.
[0003] The biggest problem with popcorn machines is that the processing materials such as rice or corn kernels at the bottom of the pot are most likely to burst due to the most heat, while the upper layer of processing materials is less likely to burst due to less heat. Once the upper layer of materials bursts, the materials at the bottom of the pot are burned, and due to the addition of oil, sugar, salt and other seasonings during the processing process, the seasonings will also harden during heating, causing the processing materials to stick to the inner surface of the pot.
[0004] In order to solve these problems, a Chinese utility model patent (CN220936635U) discloses a popcorn machine, which includes a frying pan, a closed cover is arranged above the frying pan, a planetary gear driving disc is fixed to the top of the closed cover, an electric motor is arranged on the top of the planetary gear driving disc, the output end of the electric motor is connected with the planetary gear driving disc, a connecting rod is arranged below the closed cover, the upper end of the connecting rod is connected with the planetary gear driving disc, the lower end of the connecting rod extends to the inner side of the frying pan, and a frying plate is detachably fixed to the bottom of the connecting rod.
[0005] This technical solution limits the frying pan and has no universality, and the processing materials at the bottom of the frying pan cannot be well turned over. Moreover, the electric motor is used as the drive, which is not easy to control, and the motor circuit will affect the processing of the frying pan on the gas stove.
[0006] A corn popcorn machine with a stirrer is disclosed in a US patent application (US20230309588A1), which includes a pot including one or more interior surfaces defining an interior volume of the pot; a lid assembly including a lid configured to cooperate with the pot; a crank coupled with the lid and configured to rotate relative to the lid; and a link coupled with the crank and configured to rotate with the crank; a stirrer assembly configured to be positioned within the interior volume of the pot and releasably engage the link when the lid cooperates with the pot.
[0007] The scheme is suitable for family use, but in order to fix the stirrer, the bottom of the pot is provided with a protrusion, the stirrer is provided with a through hole at the blade to match the protrusion, and the stirrer is installed on the protrusion through the through hole. The technical scheme has special requirements for the pot, the cost is too high, the ring structure of the stirrer is complicated and troublesome to install, and the ring structure of the stirrer rubs against the inner surface of the pot during stirring, which is relatively laborious.
