The central axis of the cooker 4 is positioned under the central axis of the heat-insulating shell 3, the upper three-quarters part (based on the height of the section of the cooker 4, the lower part is the same) is arranged inside the heat-insulating shell 3, the lower one-quarter part is exposed out of the heat-insulating shell 3, and the stirring rod 5 is arranged inside the cooker 4 and is coaxially installed with the cooker body. Wherein, the heat preservation shell 3 only plays a role of supporting and fixing; the cooker 4 is exposed out of the lower quarter part of the heat preservation shell 3 and is directly aligned with the gas stove 2 for heating.

Station conversion subassembly includes: support 6, gear motor 7, belt 8, band pulley 9, rotation axis 10. Two supports 6 are fixedly arranged on the cooking bench 1 on the rotating shafts 10 on two sides of the pot body, a speed reducing motor 7 is arranged on one support 6, a belt wheel 9 is connected with an output shaft of the speed reducing motor 7 through a belt 8, and the output shaft of the speed reducing motor is in key fit with the rotating shafts 10. A microswitch is arranged on the belt wheel 9 and used for detecting the rotating limit position of the pot body to prevent the pot mouth from facing to the right lower part, and a potential sensor (not shown in the attached drawing) is arranged at one side provided with the speed reducing motor 7 to control the station of the pot body. When the pot body is used for feeding dishes, the pot body can be adjusted to a dish feeding station (75-105 degrees) by rotating the speed reducing motor 7; when the pan body is used for frying, the pan body can be adjusted into a frying station (30-90 degrees) by rotating the speed reducing motor 7; when the pot body is used for serving, the pot body can be adjusted to a serving station (225-270 degrees) by rotating the speed reducing motor 7; when the pot body is used for cleaning, the pot body can be adjusted to a cleaning station (0-40 degrees) by rotating the speed reducing motor 7.

As shown in fig. 2, the stir-fry assembly comprises: a servo motor (not shown in the drawings), a first transmission assembly, a second transmission assembly and a bearing housing 15. Servo motor sets up 3 outsides of lagging casing, first drive assembly and second drive assembly set up 3 outsides of lagging casing, its one end with servo motor connects, and the other end is connected with pan 4 and puddler 5 respectively, and bearing housing 15 sets up 3 outsides of lagging casing are used for fixing first drive assembly and second drive assembly. More specifically, the first transmission assembly comprises: an output gear 11 fixedly connected with an output shaft of the servo motor, a first reduction gear set 12 meshed with the output gear 11, and a first driving shaft 13 coaxially connected with an output end of the first reduction gear set 12 and having a hollow interior; wherein the first driving shaft 13 is connected with the pot 4 through a plurality of ball bearings 14 fixedly mounted on the bearing housing 15. The second transmission assembly includes: an output gear 11 fixedly connected with an output shaft of the servo motor, a second reduction gear set 16 meshed with the output gear 11, and a second driving shaft 17 coaxially connected with an output end of the second reduction gear set 16 and penetrating the first driving shaft 13; wherein the second drive shaft 17 is connected to the agitator shaft 5 through a plurality of ball bearings 14 fixedly mounted on the first drive shaft 13. When the cooking robot works, the servo motor is started, the output gear 11 and the first speed reducing mechanism are used for transmission, the first driving shaft 13 is driven to rotate at a lower speed, and then the cooker 4 is driven to rotate at a low speed. Similarly, the output gear 11 and the first speed reducing mechanism drive the second driving shaft 17 to rotate at a higher speed, so as to drive the stirring rod 5 to rotate at a high speed. At the moment, the food materials are taken as a research object, the motion track of the food materials is a track of incomplete circular motion, namely in a vertical plane, the food materials do circular motion along the inner wall of the cooker 4, when the highest point is reached, the food materials are separated from the wall of the cooker 4, the pan throwing motion is performed, the food materials fall into the bottom of the cooker 4 again, the processes are repeated, and the stir-frying process of the food materials is realized.

The difference between the number of gears in the first reduction gear set 12 and the number of gears in the second reduction gear set 16 is an odd number. Therefore, the pot 4 and the stirring rod 5 rotate around the central axis of the heat preservation shell 3 in different directions. Moreover, differential motion is realized on the rotating speed of the pan 4 and the stirring rod 5, so that the stir-frying effect can be effectively improved.

In further implementation, because the pot 4 is thin, it is difficult to connect with the first driving shaft 13 by a nut or a bolt; therefore, the first driving shaft 13 passes through the polygonal fixing hole of the pot 4, and a fastener 18 and a sealing rubber ring 19 are provided at the protruding portion of the pot 4 to be fixed to the pot 4. The fastener 18 generates a downward force and the sealing rubber ring 19 realizes sealing. It should be noted that the thread direction of the fastener 18 is opposite to the rotation direction of the first drive shaft 13. Only in this way is it possible to maintain the screw connection tight when the first drive shaft 13 is rotated.

In the further implementation process, as shown in fig. 3-5, the pot 4 is in a spherical shape, a bottle shape or a cylindrical shape. In the embodiment, the spherical pot 4 is preferred, and compared with other two kinds of pots 4, the spherical pot 4 can heat more food materials when having the same heating area, so that the food materials can be better turned and fried, the contact area between the pot 4 and the heating equipment is increased, and the contact heating time between the food materials and the pot wall is prolonged; moreover, the opening of the pan is properly reduced, so that the probability that the food materials are thrown out of the pan in the stir-frying process is reduced. Correspondingly, the mixing rod 5 is a U-shaped shovel, the inner side of which is provided with a saw-toothed saw blade 20, the outer contour of which is matched with the shape of the pot 4, and a predetermined distance is reserved between the outer contour and the inner wall of the pot 4. On the one hand, the paddle 5 is rotating and, on the other hand, the saw blade 20 on the paddle 5 helps to break up the food material.

In a further implementation, the pot 4 and the stirring rod 5 are made of metal iron, and the inner surface of the pot is coated with a polytetrafluoroethylene coating. The polytetrafluoroethylene coating is used as a non-stick coating, has better abrasion resistance and non-stick property, avoids food materials from sticking a pot, and is convenient to clean at a later stage.

In order to facilitate understanding of the technical scheme of the stir-frying unit for the stir-frying robot, the working principle of the stir-frying unit is briefly explained: after the pot body is finished and is advanced the dish process, become stir-fry station (30 ~ 90 °) through the rotatory adjustment pot body of gear motor 7, fry the dish process, open servo motor, through output gear 11, the transmission of first reduction gears, drive first drive shaft 13 and rotate with lower speed, and then drive pan 4 low-speed rotation. Similarly, the output gear 11 and the first speed reducing mechanism drive the second driving shaft 17 to rotate at a higher speed, so as to drive the stirring rod 5 to rotate at a high speed. At this time, the food material is taken as a research object, the motion track of the food material is a track of incomplete circular motion, namely in a vertical plane, the food material does circular motion along the inner wall of the pot 4, and when the highest point is reached, the food material is separated from the wall of the pot 4, does horizontal throwing motion, falls into the bottom of the pot 4 again, and the processes are repeated. After the stir-frying process is finished, the pot body is adjusted to a dish discharging station (225-270 degrees) through the rotation of the speed reducing motor 7, and dish discharging is carried out.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, the present invention does not separately describe various possible combinations.
