Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and in particular to a driving mechanism and a cooking utensil having the same. Background Art

[0002] As an automatic cooking device, the stir-frying machine is gradually becoming popular among consumers. The automatic stir-frying machine drives the stirring blade to rotate or swing through the internal drive parts to achieve the automatic stir-frying function of the ingredients, which greatly facilitates consumers and saves time.

[0003] In the related art, since the stirring blade is arranged in the cooking cavity of the inner pot, in order to facilitate the taking and placing of the inner pot from the base, a movable coupling is usually arranged to achieve the connection or separation between the stirring blade and the output shaft of the driving member. For example, patent CN218852437U discloses a cooking machine, which can connect or separate with the stirring blade by pressing a button and driving the coupling to move horizontally through a driving mechanism.

[0004] However, the cooking appliance in the related art has a complicated driving mechanism. Utility Model Content

[0005] The utility model provides a driving mechanism and a cooking utensil with the same, so as to solve the problem of complex driving structure of a coupling in the related technology.

[0007] According to the technical solution of the utility model, the driving mechanism includes a matching piece, a magnet and a mounting frame. When the upper cover is installed on the inner pot, the magnetic force between the matching piece and the magnet can be used to drive the magnet to move. Since the magnet is fixedly installed in the mounting cavity, the magnet can drive the mounting frame to move, and then drive the coupling to move through the mounting frame to achieve the connection or separation between the stirring blade and the output shaft of the driving member. Compared with the related art in which a complex driving mechanism is set to drive the coupling to move, the magnetic force between the matching piece and the magnet is used to drive the coupling to move, which has the advantage of a simple structure. Since the magnet is fixedly installed in the mounting cavity and extends into the avoidance gap, the distance between the matching piece and the magnet is reduced, and the magnetic force between the two is increased, so that the coupling moves faster.

[0008] Furthermore, the magnet includes a magnetic body and a magnetic protrusion arranged on the magnetic body, the magnetic body is located in the installation cavity, the magnetic protrusion is located in the avoidance gap, and the surface of the magnetic protrusion is flush with the avoidance gap or protrudes from the avoidance gap.

[0010] Furthermore, on a plane perpendicular to the avoidance notch, the ratio between the projected area of ​​the magnetic protrusion and the projected area of ​​the magnetic body is between 0.8 and 0.95. The above ratio range can ensure that the matching piece and the magnet have a sufficiently large magnetic force, while preventing the magnet from detaching from the mounting frame under the action of the magnetic force.

[0011] Furthermore, the mounting frame has a pick-and-place opening connected to one side of the avoidance notch, and the area of ​​the pick-and-place opening is larger than the cross-sectional area of ​​the magnet. The magnet can be picked up and placed using the pick-and-place opening.

[0013] Furthermore, the two sides of the baffle protrude from the inner walls of the first side plate and the third side plate respectively, and the lower edge of the baffle protrudes from the upper surface of the bottom plate. With the above arrangement, the magnet can be blocked at both sides and the lower edge of the baffle, making the magnet more firmly fixed.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0033] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a driving mechanism, which is applied to a cooking utensil. The cooking utensil includes a shell 50 and an upper cover 70, and the shell has a accommodating cavity; the driving mechanism includes: a matching piece 71, a magnet 10 and a mounting frame 20, the matching piece 71 and the magnet 10 are magnetically matched, and the matching piece 71 is arranged on the upper cover 70 or the shell 50; the mounting frame 20 is arranged in the accommodating cavity, and has an installation cavity 211 for installing the magnet 10 and an avoidance gap 212, the avoidance gap 212 is connected to the installation cavity 211 and is located on a side of the installation cavity 211 close to the matching piece 71, and the magnet 10 is fixedly arranged in the installation cavity 211 and extends into the avoidance gap 212.

[0034] The technical solution of the utility model is applied, and the driving mechanism includes a matching piece 71, a magnet 10 and a mounting frame 20. When the upper cover 70 is placed on the inner pot 60, the magnetic force between the matching piece 71 and the magnet 10 can be used to drive the magnet 10 to move. Since the magnet 10 is fixedly arranged in the mounting cavity 211, the magnet 10 can drive the mounting frame 20 to move, and then drive the coupling 52 to move through the mounting frame 20, so as to achieve the connection or separation between the stirring blade and the output shaft of the driving member 51. Compared with the related art in which a complex driving mechanism is set to drive the coupling 52 to move, the magnetic force between the matching piece 71 and the magnet 10 is used to drive the coupling 52 to move, which has the advantage of a simple structure. Since the magnet 10 is fixedly arranged in the mounting cavity 211 and extends into the avoidance gap 212, the distance between the matching piece 71 and the magnet 10 is reduced, and the magnetic force between the two is increased, so that the coupling 52 moves faster.

[0035] In other embodiments, the magnet 10 is wrapped in a closed structure in a fixed manner, and the minimum distance between the fitting 71 and the magnet 10 is 6 mm. With the solution of the present application, since the magnet 10 extends into the avoidance gap 212, and the outer surface of the magnet 10 is flush with the avoidance gap 212 or protrudes from the avoidance gap 212, the distance between the fitting 71 and the magnet 10 can be reduced.

[0036] The matching piece 71 may be a magnetic piece, or a material such as iron or nickel that can be adsorbed by a magnetic piece.

[0037] It should be noted that when the matching piece 71 is disposed on the upper cover 70, the matching piece 71 can be magnetically matched with the magnet 10 during the process of the upper cover 70 being covered on the inner pot 60. When the matching piece 71 is disposed on the outer shell 50, the upper cover 70 can drive the matching piece 71 to move during the process of the upper cover 70 being covered on the inner pot 60, and drive the magnet 10 to move through magnetic matching.

[0038] like Figure 2 As shown, in the first embodiment of the present application, the magnet 10 includes a magnetic body 11 and a magnetic protrusion 12 arranged on the magnetic body 11, the magnetic body 11 is located in the installation cavity 211, the magnetic protrusion 12 is located in the avoidance gap 212, and the surface of the magnetic protrusion 12 is flush with the avoidance gap 212 or protrudes from the avoidance gap 212.

[0043] In this embodiment, the ratio between the projected area of ​​the magnetic protrusion 12 and the projected area of ​​the magnetic body 11 is between 0.8 and 0.95 on a plane perpendicular to the avoidance notch 212. The above ratio range can ensure that the matching piece 71 and the magnet 10 have a sufficiently large magnetic force, while the magnet 10 will not be separated from the mounting frame 20 under the action of the magnetic force.

[0044] The ratio of the projected area of ​​the magnetic protrusion 12 to the projected area of ​​the magnetic body 11 may be 0.8, 0.9, 0.95, or any value between 0.8 and 0.95.

With the above arrangement, the magnet 10 can be blocked at both sides and the lower edge of the baffle 217, so that the magnet 10 is fixed more firmly.
