Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen utensils, and in particular to a stirrer for a cooking machine and a cooking machine. Background Technology
[0002] Currently, more and more cooking machines or stir-fry machines are appearing on the market, capable of semi-automatic or fully automatic stir-frying. The stir-frying function basically relies on a simple rotating structure to simulate human stirring. For example, a motor is installed on the top of the pot lid, which drives a paddle-shaped spatula to rotate simply inside the pot to achieve the stirring function.
[0003] The drawback of this design is that a single rotating function often fails to achieve satisfactory cooking results. With the rotation only occurring in the center of the pot, the food inside is often pushed to the outer edge of the pot. Because the working radius of the rotating spatula is limited, it cannot scrape the outer wall, causing the food on the outer edge to quickly stick to the wall due to the high temperature until cooking is finished. This results in dishes with poor taste and texture. Utility Model Content
[0004] The technical problem to be solved by this utility model is to address the issue of poor taste in dishes caused by the single rotation function of the spatula in cooking machines and stir-fry machines, and to provide a stirrer and cooking machine for use in cooking machines.
[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0009] A stirring blade is located in the middle of the main connecting rod;
[0010] Rotary drive;
[0011] A gear set is located in the middle of the main connecting rod. The gear set has an input end, a first output end, and a second output end. The input end is connected to the rotary driver, the first output end is connected to the main connecting rod, and the second output end is connected to the stirring blade.
[0012] The gear set includes: a first-stage sun gear, a first-stage planetary gear, a second-stage sun gear, and a second-stage planetary gear;
[0013] The input terminal is connected to the first-stage sun gear, the first-stage sun gear meshes with the first-stage planetary gear, the first-stage planetary gear is connected to the second-stage sun gear, the second-stage sun gear meshes with the second-stage planetary gear, the second-stage sun gear is connected to the second output terminal, and the second-stage planetary gear is connected to the first output terminal.
[0014] In this design, the rotary driver of the stirrer has dual outputs. The high-speed output connects to the stirring blade, driving it to rotate rapidly and achieve the stir-frying function. The low-speed output drives the main connecting rod to rotate, thereby causing the scraper to rotate along the wall of the pot.
[0015] This gear set is a two-stage planetary reduction gear. On one hand, the second-stage sun gear of the high-speed stage is connected to the second output end, which is fixedly connected to the stirring blade, driving its rotation. On the other hand, the second-stage planetary gear of the low-speed stage is fixedly connected to the first output end, serving as the low-speed stage output. The output from the first output end, after being reduced by two stages, is connected to the main connecting rod, driving its rotation, thus creating a situation where the stirring blade rotates at a higher speed, while the scraper rotates at a lower speed.
[0016] Preferably, the gear set further includes a gear ring structure that meshes with the secondary planetary gear.
[0017] In this design, the secondary planetary gear meshes with the gear ring structure, making the secondary planetary gear more stable.
[0018] Preferably, the gear set further includes a base and a housing, the base being fixed to the rotary drive, the housing being fixed to the base, the gear ring structure being disposed on the inner wall of the housing, and the housing accommodating the first-stage sun gear, the first-stage planet gear, the second-stage sun gear, and the second-stage planet gear.
[0019] Preferably, the gear set further includes a planet carrier, which includes a centrally located planetary output shaft and a frame surrounding the output shaft. The secondary planetary gears are connected to the frame, and the end of the planetary output shaft furthest from the frame is the first output end.
[0020] Preferably, the planetary output shaft has a hollow structure, the center of the secondary sun gear is connected to the sun output shaft, and the end of the sun output shaft away from the secondary sun gear is the second output end, which is inserted into the planetary output shaft.
[0021] In this design, the second output end is inserted into the planetary output shaft, so that the first output end and the second output end can overlap, thereby driving the stirring to the main connecting rod at different speeds at the same point.
[0022] Preferably, a high-speed output bearing is provided between the planetary output shaft and the solar output shaft.
[0023] Preferably, the planetary output shaft extends out of the gear ring structure, and a low-speed output bearing is provided between the planetary output shaft and the gear ring structure.
[0024] Preferably, the main connecting rod is provided with a first hole, and the planetary output shaft is interference-fitted into the first hole.
[0025] In this design, the planetary output shaft is interference-fitted into the first hole, thereby ensuring good assembly.
[0026] Preferably, the secondary planetary gear is connected to the frame via a connecting pin.
[0027] A cooking machine comprising a stirrer as described above for use in a cooking machine.
[0028] In this design, the cooking machine utilizes a multi-stage planetary gear transmission in the motor, with different stages of the planetary gears providing different speed outputs. Through improvements to the gear transmission structure, a single motor achieves two outputs. The high-speed output is used for stirring with a spatula at the center of the pot, while the low-speed output drives a scraper to scrape the pot walls. This maximizes space utilization and saves costs.
[0029] The positive and progressive effects of this utility model are as follows: the rotary driver of the stirrer has dual outputs. The high-speed output is connected to the stirring blade, which drives the stirring blade to rotate quickly to realize the stir-frying function. The low-speed output drives the main connecting rod to rotate, thereby driving the scraper to rotate along the wall of the pot.
[0030] This gear set is a two-stage planetary reduction gear. On one hand, the second-stage sun gear of the high-speed stage is connected to the second output end, which is fixedly connected to the stirring blade, driving its rotation. On the other hand, the second-stage planetary gear of the low-speed stage is fixedly connected to the first output end, serving as the low-speed stage output. The output from the first output end, after being reduced by two stages, is connected to the main connecting rod, driving its rotation, thus creating a situation where the stirring blade rotates at a higher speed, while the scraper rotates at a lower speed.

The end of the sun output shaft 1551 away from the secondary sun gear 155 is the second output end, which is inserted into the planetary output shaft 1571.
[0056] The second output end is inserted into the planetary output shaft 1571, so that the first output end and the second output end can overlap, thereby driving the stirring to the main connecting rod at different speeds at the same point.
[0057] A high-speed stage output bearing 161 is provided between the planetary output shaft 1571 and the sun output shaft 1551.
[0058] The planetary output shaft 1571 extends out of the gear ring structure 1521, and a low-speed output bearing 162 is provided between the planetary output shaft 1571 and the gear ring structure 1521.

[0062] The motor output shaft 141 of the motor is fixed to the first-stage sun gear 153.
[0063] Both the scraper 120 and the mixing blade 130 are detachably mounted on the main connecting rod 110, and the user can replace the scraper 120 and the mixing blade 130 as needed.
[0064] In this embodiment, the first end of the main connecting rod 110 is connected to the scraper 120, and the second end of the main connecting rod 110 is a free end. However, this utility model is not limited to this, and scrapers 120 can also be installed at both ends of the main connecting rod 110.
