For the cooking of Chinese dishes, the taste of small-pot fried dishes is usually better than that of big-pot dishes, one of the reasons is that the materials of the small-pot dishes are heated relatively faster and more uniformly. To promote even and rapid heating of the material, existing automatic/semi-automatic cooking devices are typically equipped with a stirring mechanism that stirs the material.

For example, chinese patent document CN101836815A discloses a stirring mechanism of a cooking apparatus, which includes one or more groups of stirring rods, each group of stirring rods includes two or more stirring rods; wherein, this rabbling mechanism corresponds stirring rod group still including a set of mount pad, and the stirring rod in each stirring group articulates respectively on a mount pad, and the stirring rod in each stirring group can both be around the articulated shaft swing that this stirring rod corresponds. The rod-shaped stirring tool has the advantages that the rod-shaped stirring tool can play a good role in scattering materials, prevents the materials from being adhered and agglomerated, but has the defect that the materials are difficult to turn over. For example, for a bulk material, it is easy to cause the problem that one surface of the material sticking to the pan is heated excessively, and the other opposite surface is heated insufficiently. Therefore, the problem of uneven heating of the materials is caused, and the dish quality is affected.

Chinese patent document CN2778144Y discloses a mechanized cooking machine, which is composed of a frame, a frying pan device, a sealing device, a heat preservation shell, a fire control device, a spatula, an air-blowing burner and a control system; the frying pan is driven by the motor reducer to horizontally rotate; the frying pan is driven by a motor reducer to vertically rotate; the vertical motion of the frying pan and the horizontal motion of the frying pan are combined to realize the frying of the frying pan by the frying pan. The frying machine also has the defects of poor material stirring effect and easy push/pull of the materials to the outside of the frying pan.

As a preferred embodiment of the present invention, the stirring member is moved into the pot while the stirring assistance member is brought into contact with the rim area of the pot; the stirring member is moved out of the pot while separating the stirring auxiliary member from the pot.

In order to achieve the second object, another aspect of the present invention further provides a cooking apparatus, including a pot, a stirring auxiliary member, and a stirring system, where the stirring system includes a stirring driving device, a stirring member, and a trajectory changing mechanism; the stirring auxiliary component is provided with a contact position contacted with the cooker and a separation position separated from the cooker; wherein, in the contact position, the stirring auxiliary component is positioned above the pot and is contacted with the edge area of the pot, and the inner wall of the stirring auxiliary component is in a state of being folded towards the radial inner side of the pot; in a stirring state, the stirring auxiliary component is in a contact position, and the stirring driving device drives the stirring component to vertically rotate around the horizontally arranged stirring shaft so as to stir the materials in the pot; the track changing mechanism is connected with the stirring component and the stirring driving device and is configured to change the spatial position of the stirring shaft when the stirring component rotates, so that the material stirring part of the stirring component is close to the inner wall of the pot and the inner wall of the stirring auxiliary component in the rotating process. Wherein, material stirring portion is pressed close to mutually with the pan and the inner wall of stirring auxiliary component, both can be material stirring portion and pan and the inner wall direct contact of stirring auxiliary component, also can be material stirring portion and have certain clearance between its inner wall (the material stirring portion can take away the material that adheres to at pan inner wall and stirring auxiliary component inner wall equally this moment).

In the technical scheme, the rotating track of the material stirring part is adjusted by the track changing mechanism, so that the material stirring device can be adapted to pots with different shapes (such as a spherical pot and a flat-bottom pot); the track changing mechanism can also limit the rotation range of the material stirring part outside the cooker, and is beneficial to the miniaturization of the stirring auxiliary component and the cooking equipment. The stirring auxiliary component is separated from the cooker, so that the cooker is convenient to miniaturize and to be used for serving dishes. In contrast, in the solution disclosed in CN2778144Y, the cooking pan rotates vertically and the center of rotation of the cooking pan remains unchanged, so that the range of space occupied by the cooking pan when the cooking pan rotates outside the pot is very large, which results in a significant increase in the volume of the apparatus.

Fig. 11 is a front sectional view of the preferred embodiment of the cooking apparatus of the present invention, when cooking, with a sectional plane passing through the central axis of the pot 21. As can be seen from fig. 11, in the preferred embodiment of the cooking apparatus of the present invention, the inner wall of the stirring auxiliary member 22 is formed into a circular arc surface, the stirring auxiliary member 22 and the inner wall of the pot 21 form a circular arc smooth transition, and the radius of the stirring auxiliary member 22 is smaller than that of the pot 21. The cam member 421 is correspondingly provided with a track groove 4212 as shown in fig. 10, when the roller 4231 is located in the track of the section a-D, the material stirring part 431 and the inner wall of the pot 21 do the approaching movement; when the roller 4231 is positioned in the track of the section A-B, the material stirring part 431 and one side of the inner wall of the stirring auxiliary member 34 do approaching movement; when the roller 4231 is positioned in the track of the section B-C, the material stirring part 431 rotates to the position above the stirring auxiliary member 34 and starts to idle; when the roller 4231 is located in the trajectory of section C-D, the material stirring portion 431 contacts the stirring auxiliary member 34 downward and starts to move close to the other side of the inner wall of the stirring auxiliary member 34. The material is driven by the material stirring portion 431 to rise to the stirring auxiliary member 34 along the curved surface formed by the inner walls of the pot 21 and the stirring auxiliary member 34, and the material falls back into the pot 21 after being turned over by the stirring auxiliary member 34.

In the invention, the track changing mechanism can ensure that the material stirring part 431 is close to the inner walls of the pot 21 and the stirring auxiliary component 34 during stirring, and can limit the rotating range of the material stirring part 431 outside the range of the pot, thereby being convenient for the miniaturization of cooking equipment. If an angle is expressed, if there is no track changing mechanism, then to ensure that the material stirring part 431 is close to the inner wall of the pot 21 during stirring, a spherical pot must be used, and the radius of rotation of the material stirring part 431 is approximately equal to that of the spherical pot, so it is easy to understand that the range of rotation of the material stirring part 431 in this situation is very large, and the volume of the stirring auxiliary member and the equipment is increased significantly.

It should be noted that the multi-link mechanism can also implement complex known motion rules and trajectories in a plane/space, so in other embodiments of the present invention, the trajectory transformation mechanism can also be implemented by using the multi-link mechanism.

The cooking device of the preferred embodiment of the present invention can be used to call a cooking program by using a control system to execute the following cooking method:

⑴ controlling the automatic feeding system to feed cooking materials into the pot;
