Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment of the utility model provides a cooking utensil can be automatic cooking machine, flour-mixing machine, soybean milk machine, meat grinder etc. need install agitating unit's utensil, and when cooking utensil was soybean milk machine, meat grinder, the paddle on its agitating unit was the blade. The embodiment of the utility model takes an automatic cooker as an example for explanation.

With the improvement of the quality of life of people, cooking equipment tends to be automated gradually. For example, the automatic cooker is a new generation of intelligent cooking equipment controlled by a microcomputer, and has the characteristics of no radiation, no oil smoke, oil and electricity saving, automatic stir-frying and the like. Automatic cooking machines generally comprise: heating base, pan and with the pot cover that the heating base electricity is connected, install agitating unit on the pot cover, rotate through motor drive agitating unit and replace the food in the continuous stirred tank of slice to it is even to make edible material be heated, avoids edible material to burn, burns out the taste in order to guarantee to process food, realizes automatic culinary art process.

However, in the actual cooking process, along with the difference of the food materials, the stirring effect of the food materials can also show a large difference, and particularly, the phenomenon that the stirring paddle is blocked is easily caused when the food materials with high viscosity or the food materials with large quantities are stirred, so that the food materials cannot be continuously stirred, the food materials are burnt and burnt, the taste is influenced, and potential safety hazards also exist.

In view of this, the embodiment of the utility model provides a cooking utensil, in normal use, first drive arrangement drive paddle horizontal rotation stirs edible material, when meetting the paddle and being blocked, second drive arrangement starts and drives the paddle and follow the rotatory certain angle of center pin of paddle to the slope form, is less inclination with the original great inclination adjustment of paddle, and the resistance that the paddle received reduces, then normally stirs again. The technical problem that the stirring paddle of the cooking utensil is blocked can be solved, so that the stirring paddle can normally stir viscous or large-amount food materials.

The invention is described below with reference to the accompanying drawings in conjunction with specific embodiments.

Fig. 1 is a schematic structural diagram of a cooking appliance provided in an embodiment of the present invention, fig. 2 is a top view of the cooking appliance provided in an embodiment of the present invention, and fig. 3 is a cross-sectional view along a sectional line a-a in fig. 2.

Referring to fig. 1 to 3, a cooking appliance 100 according to an embodiment of the present invention includes: the container 200 with the cooking cavity and the cover assembly 300 covering the container 200 can provide a bearing space and a heat preservation space for food materials, and can prevent the food materials from splashing, and the cover assembly 300 covers the container 200 to prevent sundries from falling into the container 200 to pollute the food. Wherein the cover assembly 300 includes a housing 500 and a stirring assembly 600 disposed on the housing 500.

The stirring assembly 600 includes: a first driving means 610, a second driving means 620 and a paddle 630, the paddle 630 being located in the container 200 for stirring the food material. The first driving device 610 is rotatably connected with the paddle 630, and the first driving device 610 is used for driving the paddle 630 to rotate horizontally, that is, the first driving device 610 drives the paddle 630 to rotate clockwise or counterclockwise so as to achieve the purpose of stirring food materials.

Certainly, the utility model discloses more than this, fig. 4 is the utility model provides a cooking utensil's the section view when just to the paddle, fig. 5 is the enlarged schematic view of part B structure in fig. 4, fig. 6 is the section view of the cooking utensil that the embodiment of the utility model provides when just to the paddle and behind the paddle angle adjustment angle that provides, fig. 7 is the enlarged schematic view of part C structure in fig. 6, refer to fig. 4 to 7 and show, second drive arrangement 620 is connected with paddle 630, and second drive arrangement 620 is used for driving paddle 630 to rotate to the slope form.

For example, as shown in fig. 4 and 5, when the cooking appliance 100 is in normal use, the first driving device 610 drives the paddle 630 to horizontally rotate to stir the food material, and to ensure the stirring effect of the food material, the paddle 630 often needs to maintain a larger inclination angle, but this also increases the resistance of the paddle 630 to stir the food material, and particularly when the food material with high viscosity or a large amount of food material is stirred, the paddle 630 is easily jammed. At this time, the second driving device 620 drives the blades 630 to rotate, as shown in fig. 6 and 7, the second driving device 620 drives the blades 630 to rotate to reduce the inclination angle of the blades 630, the resistance of the blades 630 is reduced, and the stirring assembly 600 can resume normal stirring.

Here, the inclination angle of the blade 630 means an angle α between the blade 630 and the horizontal direction. Alpha can be more than or equal to 10 degrees and less than 90 degrees, so that the blades 630 have a certain inclination angle during stirring, and the stirring quality of food materials is improved. Moreover, when the paddle 630 is clamped, the inclination angle of the paddle can be adjusted, so that the resistance is reduced, and the problem that the paddle 630 is clamped is solved.

It should be noted that, referring to fig. 1 to 3, the cooking apparatus 100 provided in the embodiment of the present invention may further include: a base 400.

The control unit may also be used to control the stirring assembly 600, for example, to adjust the switching, the rotation speed, the rotation direction, etc. of the stirring assembly 600.

With continued reference to fig. 5, in some embodiments of the present invention, a distance L1 between a central axis of the vertical turning of the paddle 630 and one of the turned edges of the vertical turning of the paddle 630 is greater than a distance L2 between the central axis of the vertical rotation of the paddle 630 and the inner bottom surface of the cooking cavity.

It is easy to understand that L1 is larger than L2, so that the paddle 630 is as close to the inner bottom surface of the container 200 as possible, the food material can be stirred more uniformly, and the stirring effect of the food material is ensured. On the other hand, when the paddle 630 is rotated from a smaller inclination angle to a larger inclination angle, the inner bottom surface of the container 200 may prevent the paddle 630 from continuing to rotate, preventing the paddle 630 from rotating to be perpendicular to the inner bottom surface of the container 200, resulting in excessive resistance during stirring.
