Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, and in particular to an automatic stirring structure for a porridge cooker. Background Technology

[0002] Porridge cooking, a common traditional cooking method, relies heavily on stirring for its texture and evenness. Thorough stirring prevents ingredients from settling and burning at the bottom, ensures even heating, and enhances the porridge's flavor. With the development of intelligent kitchen appliances, automatic stirring porridge cookers are increasingly entering home and commercial settings. These cookers use mechanical structures to replace manual stirring, reducing labor intensity and increasing cooking efficiency. Currently, most automatic stirring porridge cookers on the market consist of a drive mechanism and a stirring component. The core function is to use a transmission component to drive the stirring component to rotate, thus achieving the stirring function and meeting users' needs for convenient cooking.

[0003] However, existing automatic stirring porridge cookers mostly have an integrated stirring structure, which easily leaves porridge residue in the gaps, making cleaning difficult and prone to bacterial growth with long-term use, affecting hygiene. The stirring speed of existing automatic stirring porridge cookers is mostly fixed, unable to adjust according to the different stages of porridge cooking (such as water absorption, boiling, and thickening stages), resulting in insufficient stirring uniformity and a tendency for scorching or overflowing. The supporting stability of the stirring structure in existing automatic stirring porridge cookers is poor, easily causing shaking during stirring, which not only affects the stirring effect but may also reduce the lifespan of the equipment. Furthermore, existing automatic stirring porridge cookers lack effective load and viscosity monitoring mechanisms, failing to achieve adaptive stirring and relying on manual intervention, thus lacking ease of use.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] The present invention discloses an automatic stirring structure for a porridge cooker, including a drive component 1 and a stirring component 2. The drive component 1 is installed inside the working box at the top of the porridge cooker, and the stirring component 2 is set in the pot body of the porridge cooker. The automatic stirring function of the porridge is achieved through the cooperation of the two. The stirring assembly 2 is connected to the bottom of the drive assembly 1 via bearings to ensure the stability of the transmission process. The stirring assembly 2 includes a column 21, a stirring frame 22, and a stirring paddle 23. The column 21 is connected to the bottom of the drive assembly 1 via bearings, providing core support for the entire stirring structure. The stirring frame 22 is fixedly welded to the bottom of the column 21. The stirring frame 22 forms a three-dimensional support effect through multiple rails, which, together with the feet 214 at the bottom of the column 21, disperse the force generated during the stirring process, effectively preventing the porridge pot from shaking during operation. At the same time, its large longitudinal coverage area can fully contact the porridge, ensuring the uniformity of the porridge stirring. The stirring paddle 23 is installed on the front and rear sides of the bottom of the stirring frame 22, and its bottom end is close to the bottom of the porridge pot, which can stir the porridge at the bottom of the pot and prevent it from sticking to the bottom. In particular, the stirring paddle 23 adopts a detachable design, which can be easily removed for individual cleaning after use, completely solving the problem of dirt and grime easily accumulating in the gaps of traditional stirring structures, ensuring hygiene during use. See details. Figure 1 .

[0017] The column 21 includes a top column 211, a locking member 212, a stirring shaft 213, and a foot 214. The top column 211 is located at the top of the column 21. The locking member 212 is threaded to the bottom of the top column 211. The stirring shaft 213 is threaded to the bottom of the locking member 212. The locking member 212 securely installs the stirring shaft 213 and the top column 211. The foot 214 is located at the bottom of the stirring shaft 213 and is embedded in the bottom of the porridge pot. The foot 214 firmly fixes the column 21 to the central axis of the porridge pot, further improving the stability of the entire stirring structure and preventing displacement during stirring. The stirring rack 22 consists of a crossbar 221, a vertical rod 222, and a fixing rod 223. The crossbar 221 is inserted through the top of the stirring shaft 213 and welded in place. Several vertical rods 222 are evenly arranged on both sides of the stirring shaft 213, with their tops welded to the bottom of the crossbar 221. The top surface of the fixing rod 223 is welded to the bottom of the vertical rod 222 and inserted through the bottom of the stirring shaft 213. The interconnection of the crossbar 221, vertical rod 222, and fixing rod 223 forms a stable, railing-like three-dimensional support structure, which can both distribute the stirring force and increase the contact area with the porridge, ensuring thorough stirring. The stirring paddle 23 is bolted to the front and rear sides of the fixing rod 223 and is detachable, allowing users to easily disassemble, clean, or replace it according to their needs. The stirring paddle 23 can be cleaned separately after disassembly, avoiding the problem of dirt accumulating in the crevices. See details. Figure 2 .

[0018] The drive assembly 1 consists of a gearbox 11, a variable frequency motor 12, an output flange 13, a rotating support 14, and a mounting platform 15. The gearbox 11 is located at the top of the drive assembly 1. The variable frequency motor 12 is connected to the left side of the gearbox 11 via a flange. The output flange 13 at the bottom of the gearbox 11 is bolted to its bottom surface. The top surface of the rotating support 14 is tightly fitted to the bottom surface of the output flange 13 and is connected to the top of the column 21 via a bearing. The rotating support 14 is bolted to the mounting platform 15. The mounting platform 15 is bolted to the working box on top of the porridge cooker, ensuring the entire drive assembly 1 is stably mounted on the porridge cooker and guaranteeing the stability of the transmission process. The variable frequency motor 12 is connected to the control system. During the porridge cooking process, the control system monitors the stirring load and viscosity in real time through a torque sensor installed between the output flange 13 and the rotating support 14. It also automatically adjusts the input frequency of the variable frequency motor 12 via a frequency converter, thereby changing the motor speed. The motor speed is converted by the fixed transmission ratio of the reduction gearbox 11, outputting a stirring speed adapted to the current state of the porridge. This achieves adaptive adjustment of the stirring speed, ensuring optimal stirring results at different stages of porridge cooking. This guarantees a uniform texture and effectively prevents scorching and overflow. See details... Figure 3 .

[0019] Through the rational coordination of its various components, the automatic stirring structure not only achieves automatic and thorough stirring of the porridge, but also solves the problems of inconvenient cleaning, fixed stirring speed, and easy shaking during use of traditional stirring structures, significantly improving the convenience and practicality of cooking porridge.
