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 uses the internal motor to drive the stirring blade to rotate or swing, realizing 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 motor.

[0004] However, the cooking machine in the related art drives the coupling to move by setting a sleeve, and the sleeve can only drive the coupling to move in one direction. The movement of the coupling in the other direction requires the help of a reset spring, which is costly. Utility Model Content

Since the installation opening is arranged on the driving frame, compared with the sleeve structure in the related art, less material is required and the cost is lower. In addition, by utilizing the cooperation of the connecting protrusion and the connecting groove, the setting of the reset spring can be omitted, further reducing the cost.

[0008] Furthermore, the coupling includes a connecting shaft and a vertical plate arranged on the outer side wall of the connecting shaft, the vertical plate extends into the installation opening, the connecting protrusion is arranged on one of the vertical plate and the driving frame, and the connecting groove is arranged on the other of the vertical plate and the driving frame. The coupling adopting the above structure can reduce the radial size of the connecting shaft by arranging the vertical plate, thereby saving materials and reducing costs.

[0009] Further, on the side of the first plane away from the driving frame, the vertical projection of the connecting groove along the central axis of the coupling and the vertical projection of the connecting protrusion along the central axis of the coupling have an overlapping area, wherein the first plane is a horizontal plane, and the central axis of the coupling is located in the first plane. With the above arrangement, the connecting protrusion or the connecting groove can be extended below the central axis of the coupling, thereby connecting the connecting protrusion or the connecting groove to both the upper half and the lower half of the coupling, so that the connection between the two is more stable.

[0010] Furthermore, the driving frame includes an arc-shaped arm, a first limiting arm and a second limiting arm, the first limiting arm and the second limiting arm are respectively connected to two ends of the arc-shaped arm, and the inner side wall of the arc-shaped arm, the inner side wall of the first limiting arm and the inner side wall of the second limiting arm together form a mounting opening.

With the above arrangement, the arc-shaped arm can be plugged and matched with the upper part of the connecting protrusion, and the first limiting arm and the second limiting arm can be plugged and matched with the lower part of the connecting protrusion, so that the coupling is more stable when moving.

[0012] Furthermore, the lengths of the first limiting arm and the second limiting arm are the same, and the radius of the arc-shaped arm is greater than the length of the first limiting arm. With the above structure, while facilitating the removal of the coupling from the installation opening, it further saves materials and saves costs; the length of the first limiting arm is less than or equal to 20 mm. With the above size setting, it is possible to form a plug-in fit with the connecting protrusion while facilitating the connection protrusion to be removed from the installation opening.

[0013] Furthermore, in the axial direction and radial direction of the coupling, the connecting protrusion and the connecting groove are clearance-fitted. The clearance-fitting method has the advantage of being easy to disassemble and assemble.

[0034] 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.

[0035] like Figures 1 to 3 As shown, an embodiment of the utility model provides a driving mechanism, which includes a driving frame 10 and a coupling 20, wherein the driving frame 10 has a mounting opening 11; the coupling 20 is inserted into the mounting opening 11 along its radial direction; wherein, one of the driving frame 10 and the coupling 20 is provided with a connecting protrusion 31, and the other of the driving frame 10 and the coupling 20 is provided with a connecting groove 32, and the connecting protrusion 31 is inserted into the connecting groove 32.

[0036] By applying the technical solution of the utility model, the driving mechanism includes a driving frame 10 and a coupling 20. Since one of the connecting protrusion 31 and the connecting groove 32 is arranged on the driving frame 10, and the other of the connecting protrusion 31 and the connecting groove 32 is arranged on the coupling 20, and the connecting protrusion 31 is inserted into the connecting groove 32, the driving frame 10 can drive the coupling 20 to move, so as to realize the connection or separation between the stirring blade and the output shaft of the driving member 61. Since the installation opening 11 is arranged on the driving frame 10, compared with the sleeve structure in the related art, less material is required and the cost is lower. In addition, by utilizing the cooperation of the connecting protrusion 31 and the connecting groove 32, the setting of the reset spring can be omitted, further reducing the cost.

[0037] It should be noted that, since the sleeve can only contact the coupling 20 through one side, the sleeve can only drive the coupling 20 to move in one direction. At this time, a reset spring is required to achieve the reset of the coupling. In this embodiment, since the two sides of the connecting protrusion 31 can be respectively fitted with the two sides of the connecting groove 32, the driving frame 10 can drive the coupling 20 to move back and forth along a straight line.

[0038] like Figure 1 and Figure 3 As shown, the coupling 20 includes a connecting shaft 21 and a vertical plate 22 disposed on the outer side wall of the connecting shaft 21, the vertical plate 22 extends into the mounting opening 11, the connecting protrusion 31 is disposed on one of the vertical plate 22 and the driving frame 10, and the connecting groove 32 is disposed on the other of the vertical plate 22 and the driving frame 10. The coupling 20 with the above structure can reduce the radial dimension of the connecting shaft 21 by disposing the vertical plate 22, thereby saving materials and reducing costs.

[0039] In this embodiment, on the side of the first plane away from the drive frame 10, the vertical projection of the connecting groove 32 along the central axis of the coupling 20 and the vertical projection of the connecting protrusion 31 along the central axis of the coupling 20 have an overlapping area, wherein the first plane is a horizontal plane, and the central axis of the coupling 20 is located in the first plane. With the above arrangement, the connecting protrusion 31 or the connecting groove 32 can be extended to below the central axis of the coupling 20, and then the connecting protrusion 31 or the connecting groove 32 is connected to both the upper half and the lower half of the coupling 20, so that the connection between the two is more stable.

[0040] It should be noted that the first plane is a horizontal plane where the central axis of the coupling is located. The side of the first plane away from the driving frame 10 refers to the bottom of the first plane.

[0041] The vertical projection of the connecting groove 32 along the central axis of the coupling 20 refers to the projection of the connecting groove 32 on the vertical plane. The vertical projection of the connecting protrusion 31 along the central axis of the coupling 20 refers to the projection of the connecting protrusion 31 on the vertical plane.

[0042] like Figure 2 As shown, the driving frame 10 includes an arc-shaped arm 12, a first limiting arm 13 and a second limiting arm 14, the first limiting arm 13 and the second limiting arm 14 are respectively connected to the two ends of the arc-shaped arm 12, and the inner side wall of the arc-shaped arm 12, the inner side wall of the first limiting arm 13 and the inner side wall of the second limiting arm 14 together form a mounting opening 11. The driving frame 10 manufactured using the arc-shaped arm 12, the first limiting arm 13 and the second limiting arm 14 can further save materials and reduce costs.

[0043] In this embodiment, the arc-shaped arm 12 , the first limiting arm 13 and the second limiting arm 14 together form a semi-annular structure.

[0044] like Figure 2 and Figure 3 As shown, the connection protrusion 31 is arranged on the outer side wall of the vertical plate 22, the connection protrusion 31 is an annular structure, the connection groove 32 is arranged on the inner side wall of the installation opening 11, and the end of the connection groove 32 extends to the mouth of the installation opening 11. With the above arrangement, the connection protrusion 31 can be easily removed from the installation opening 11 through the arrangement of the annular structure.

[0045] The end of the connecting groove 32 extends to the mouth of the installation opening 11 , which means that the connecting groove 32 passes through the inner side walls of the first limiting arm 13 and the second limiting arm 14 .

[0046] like Figure 2 As shown, the arc-shaped arm 12 is a semicircular structure, the first limiting arm 13 and the second limiting arm 14 are both straight structures, and the first limiting arm 13 and the second limiting arm 14 are both tangent to the arc-shaped arm 12. With the above arrangement, the arc-shaped arm 12 can be plugged and matched with the upper part of the connecting protrusion 31, and the first limiting arm 13 and the second limiting arm 14 can be plugged and matched with the lower part of the connecting protrusion 31, so that the coupling 20 is more stable when it moves.

[0047] In other embodiments, the first limiting arm 13 and the second limiting arm 14 may also be configured as an outwardly extending structure, that is, the opening size of the installation opening 11 gradually increases to facilitate assembly and disassembly of the connecting protrusion 31 and the connecting groove 32 .

[0048] The first limiting arm 13 and the second limiting arm 14 have the same length, and the radius of the arc-shaped arm 12 is greater than the length of the first limiting arm 13. The above structure not only facilitates the removal of the coupling 20 from the installation opening 11, but also further saves materials and costs.

[0049] In this embodiment, the length of the first limiting arm 13 is less than or equal to 20 mm. With the above-mentioned size setting, it is possible to form a plug-in fit with the connecting protrusion 31 and facilitate the connecting protrusion 31 to be removed from the installation opening 11 .

[0050] The length of the first limiting arm 13 can be 5 mm, 10 mm, 15 mm, 20 mm, or any value less than or equal to 20 mm.

[0051] Specifically, the connection protrusion 31 and the connection groove 32 are clearance-fitted in the axial direction and the radial direction of the coupling 20. The clearance-fitting method has the advantage of being easy to assemble and disassemble.

[0052] like Figure 1 As shown, the driving mechanism further includes a driving block 40, which is connected to the driving frame 10 to drive the driving frame 10 to move. When the upper cover 80 is covered on the inner pot 70, the upper cover 80 drives the driving frame 10 to move through the driving block 40, which has the advantage of simple structure.

[0053] The driving block 40 is connected to the driving frame 10 via connecting ribs.

[0054] It should be noted that a pressure block can be provided on the upper cover 80 and an inclined surface can be provided on the driving block 40. The driving block 40 is driven to move by the pressing block and the inclined surface fitting together, thereby driving the driving frame 10 to move, so that the driving frame 10 drives the coupling 20 to move.

[0055] Of course, a first magnetic component may be provided on the upper cover 80 and a second magnetic component may be provided on the driving block 40 , and the magnetic force between the first magnetic component and the second magnetic component may be used to drive the driving block 40 to move, thereby driving the driving frame 10 to move.

The guide rod 50 can be used to guide the driving frame 10 so that the driving frame 10 moves along the extension direction of the guide rod 50.

[0057] like Figures 4 to 7As shown, another embodiment of the utility model provides a cooking utensil, the cooking utensil comprises an outer shell 60, an inner pot 70, an upper cover 80 and a driving mechanism, wherein a driving member 61 is arranged in the outer shell 60; the inner pot 70 is arranged in a removable manner on the outer shell 60, and a rotatable stirring blade is arranged in the inner pot 70; the upper cover 80 is arranged on the upper part of the inner pot 70 in an openable and closable manner; the driving frame 10 of the driving mechanism is arranged in the outer shell 60, and the upper cover 80 can drive the driving frame 10 to move to drive the coupling 20 to move, thereby connecting or disconnecting the stirring blade and the output shaft of the driving member 61, and the driving mechanism is the driving mechanism provided above. In the application of the cooking utensil, when the upper cover 80 is arranged on the inner pot 70, the upper cover 80 can drive the driving block 40 to move, thereby driving the driving frame 10 to move, and the driving frame 10 drives the coupling 20 to move, so as to realize the connection between the stirring blade and the output shaft of the driving member 61, and then the driving member 61 drives the stirring blade to rotate, so that the food in the inner pot 70 can be stir-fried. When the upper cover 80 is opened by the inner pot 70, the coupling 20 can be driven to move in the opposite direction, so that the stirring blade and the output shaft of the driving member 61 are separated, so that the inner pot 70 can be taken out of the outer shell 60. Since the drive frame 10 is provided with a mounting opening 11, and the mounting opening 11 is provided with a connecting protrusion 31 or a connecting groove 32, compared with the sleeve structure in the related art, less material is required and the cost is lower. In addition, by using the cooperation of the connecting protrusion 31 and the connecting groove 32, the setting of the return spring can be omitted, further reducing the cost.
