For example, can set up the stirring procedure that this cooking function corresponds according to the different cooking functions of cooking machine (for example, make soybean milk, preparation fruit juice etc.). When the user selects a cooking function, the cooking machine can stir according to the stirring program of this cooking function of predetermineeing. Specifically, can set up the high position of cooking machine during operation puddler subassembly and when the stirring at this high position according to different cooking functions. Of course, in same cooking function, can set up to the puddler subassembly and can stir in a plurality of not co-altitude positions. It may also be provided that the stirring rod assembly is capable of repeated cyclic stirring at a plurality of height positions.

Further, please refer to fig. 3 to 7, the main body 1b is provided with a plurality of position switches 17, and the control circuit board 5 is electrically connected to the position switches 17. The connecting beam 2243 is provided with a touch part 2244, the touch part 2244 can touch the position switch 17 in the ascending or descending process of the stirring motor assembly 22, the position switch 17 can touch a signal to the control circuit board 5, and the control circuit board 5 can control the working state of the rack and pinion driving device (for example, control the working state of the first driving motor 19) according to the touch signal, so as to control the stirring rod assembly 24 to move up and down along the main machine 1 b. Through the cooperation of position switch 17 and touch 2244, can realize the automatic positioning of puddler subassembly.

In some embodiments, the position switch 17 is a microswitch. The position switch is provided on the main body 1b via the switch bracket 16. The position switch 17 includes a first microswitch 171, a second microswitch 173 positioned below the first microswitch 171, and a third microswitch 172 positioned between the first microswitch 171 and the second microswitch 173. The first micro switch 171, the second micro switch 173, and the third micro switch 172 are respectively disposed on the main body 1b through the first switch bracket 161, the second switch bracket 163, and the third switch bracket 162. A first microswitch 171 and a second microswitch 173 are provided on either side of the rack and pinion assembly. The third microswitch 172 is provided on the same side as the first microswitch 171.

For example, the first driving motor 19 may be controlled to stop, and the connecting beam 2243 and the stirring motor assembly 22 may stop descending. At this time, it can be understood that the agitating bar assembly 24 is lowered to the lowermost position. The stirring rod assembly 24 is at the lowest position and can stay at the lowest position, and the stirring rod assembly 24 can stir the food material. This lowest position can be considered an operating position of the agitator bar assembly 24. Of course, the control circuit board 5 can also control the first driving motor 19 to rotate reversely, so that the stirring rod assembly 24 can move upwards.

Based on the above structure, the touch part 2244 touches the third micro switch 172, the third micro switch 172 can generate a third touch signal to the control circuit board 5, and the control circuit board 5 can control the operating state of the first driving motor 19 according to the third touch signal. For example, the first driving motor 19 may be controlled to stop moving, and the connecting beam 2243 and the stirring motor assembly 22 may stop moving up and down. It will be appreciated that the agitator bar assembly 24 can remain in a height position between the initial position and the lowermost position. The paddle assembly 24 can paddle food material at these height positions. This height position can be considered as another operating position of the stirring rod assembly 24. Of course, the control circuit board 5 can also control the first driving motor 19 to continue rotating or rotate reversely, so that the stirring rod assembly 24 can move up and down.

It should be noted that the microswitches may be disposed on the same side, or may be disposed on two sides of the rack-and-pinion assembly in other combination manners, for example, the first and second microswitches are disposed on the same side, and the third microswitch 172 is disposed on the other side. The first and second microswitches may also be provided with a plurality of second microswitches. The present application is not limited to this, and may be set according to a specific application environment.

It should be noted that, for the embodiment that the stirring rod assembly is directly connected to the rack and pinion driving device without the stirring motor assembly, a touch part may be disposed on the stirring rod assembly, the touch part can touch the position switch during the up-and-down movement of the stirring rod assembly along the host, the position switch generates a touch signal to the control circuit board, and the control circuit board can control the working state of the rack and pinion driving device according to the touch signal to control the lifting of the stirring rod assembly. Or a touch part can be arranged on the guide sliding block.
