The stirring apparatus 100 is for driving a stirrer 200 by driving a driving motor (not shown). The stirring apparatus 100 includes a driving unit 240 and a rotation unit 250.

The drive unit 240 is installed on the upper support 120 installed horizontally at the upper end of the frame unit and includes a drive shaft 242 provided inside the end of the upper support 120 by the drive shaft support 242A and a drive shaft 242 And a driving gear 244 coupled to a lower end of the driving gear 244. A driven sprocket 247 is coupled to the upper end of the drive shaft 242. The driven sprocket 247 is connected to a driving sprocket (not shown) of the driving motor provided in the upper support 120 or the frame portion by the chain, and the driving shaft 242 is driven when the driving motor is driven. The drive shaft support 242A rotatably supports the drive shaft 242 and rotatably couples the housing 252 of the rotation unit 250. The drive shaft 242 is coupled to the drive shaft 242, The housing 252 is coupled with the base ring B.

The rotary part 250 is coupled while wrapping the drive shaft support body 242A of the drive part 240 and a bay ring B is provided between the upper end inner circumferential surface and the lower end of the drive shaft support body 242A. A driven shaft 256 coupled to one end of the driven gear 254 engaged with the drive gear 244 is provided in the housing 252. At this time, the lower end of the driven shaft 256 is exposed downward of the housing 252, and the driven shaft 256 is coupled to be rotatably supported inside the housing 252.

With this structure, when the drive gear 244 rotates while the driven gear 254 of the driven shaft 256 is engaged with the drive gear 244, the driven gear 254 is engaged with the drive gear 244 So that it revolves around the driving gear 244 while rotating. That is, the driven shaft 256 rotates around the driving gear 244 while rotating.

Meanwhile, a container 110 is provided below the upper support 120. The container 110 accommodates agitated materials (food or the like) and can be made of a large cooker for cooking with an angle adjusting device. At this time, the support stirrer 100 of the large pot may be coupled, or the large pot and the stirring device 100 may be separately configured and coupled to each other.

On the other hand, the inside of the container 110 made of a large cooker is curved so that the bottom region 112, the side wall region 116, and the boundary region 114 are curved. The first and second and third blades 272C, 274C and 276C are smoothly formed between the bottom region 112 and the sidewall region 116 and the boundary region 114 So that the food can be scraped and agitated.

The connection support member 260 coupled to the lower end of the driven shaft 256 is formed in a plate shape of a flat triangle and has three first, second, and third corner coupling ends 262, 264, 266 having coupling holes, The first and second corner coupling ends 264 and 266 are bent upward at angles a1 and a2 and the center portion 261 is formed at the center of the driven shaft 256 (Lower end) of the driven shaft 256 to rotate and revolve according to the rotation and revolution of the driven shaft 256. [

The first corner coupling end 262 of the connection support member 260 is formed in a horizontal state so as to be coincident with the center portion 261 and the second and third corner coupling ends 264 and 266 are inclined at angles a1 and a2 The first, second, and third stirring rods 272, 274, 276 coupled to the first, second, and third corner coupling ends 262, 264, 266 are rotated and rotated in different trajectories at different angles a1, a2, And the inside surface of the container 110 is stirred to stir the stirring object. The second corner joining end 264 is upwardly bent at an angle a1 of about 5-10 degrees with respect to the horizontal line L1 while the third corner joining end 266 is bent upward To an angle a2 of approximately 10 - 20 degrees.

When the first corner coupling end 262 is horizontal and flat like the center portion 261, the first stirring rod 272 coupled to the first corner coupling end 262 is parallel to the vertical line L2 The second stirring rod 274 coupled to the second corner coupling end 264 that is bent upward at an angle a1 of about 5-10 degrees with respect to the horizontal line L1 is perpendicular to the vertical line L2 Is inclined at an angle a3 of approximately 5-10 degrees with respect to the horizontal line L1 and is coupled to the third corner coupling edge 266 upwardly bent at an angle a2 of approximately 10-20 degrees with respect to the horizontal line L1 The third stirring rod 276 is tilted at an angle a4 of approximately 10 - 20 degrees with respect to the vertical line L2.

Therefore, since the first, second, and third stirring rods 272, 274, 276 are installed at different angles a1, a2 at different positions, when the connecting and supporting member 260 revolves while rotating, And the three stirring rods 272, 274 and 276 stir the inside of the container 110 tightly.

Although the connection support member 260 is formed in a triangular shape so as to form three corner coupling ends 262, 264 and 266 in the present embodiment, it is not limited thereto. The connection supporting member 260 may be formed in a rectangular or pentagonal shape, .

The agitating unit 270 includes first, second, and third stirring rods 272, 274, 276 coupled to the first, second, and third corner connecting ends 262, 264, 266. The first, second, and third stirring rods 272, 274, 276 have inner support rods 272A, 274A, 276A each of which is coupled to the first, second, and third corner coupling ends 262, 264, 266 of the connection support member 260, And outer support rods 272B, 274B, and 276B that are formed in a hollow shape so as to insert the respective inner support rods 272A, 274A, and 276A. The outer support rods 272B, 274B and 276B are rotated about the inner support rods 272A, 274A and 276A with the inner support rods 272A, 274A and 276A inserted in the outer support rods 272B, 274B and 276B A support 275 having a polygonal inner diameter is coupled to the upper ends of the outer support rods 272B, 274B and 276B so that the inner support rods 272A and 274B And 276A are formed in a polygonal shape so as to be inserted into the inner diameter of the support 275. [

With this structure, the outer support rods 272B, 274B, and 276B are always moved downward by their own weight, and self rotation is prevented. That is, a support 275 having a polygonal inner diameter is coupled to the upper ends of the outer support rods 272B, 274B, and 276B, and the middle and lower ends of the polygonal inner support rods 272A, 274A, The outer support rods 272B, 274B and 276B are allowed to flow only in the longitudinal direction of the inner support rods 272A, 274A and 276A, that is, upward and downward.

This structure allows the outer support rods 272B, 274B and 276B to move downward due to their own weight so that the first, second and third blades 272C, 274C and 276C are brought into close contact with the bottom of the container 110 with an appropriate pressure. will be.

At this time, the outer support rods 272B, 274B, 276B are moved downward with respect to the inner support rods 272A, 274A, 276A so that the outer support rods 272B, 274B, 276B can be moved downward by their own weight, To prevent the first, second and third blades 272C, 274C and 276C from being brought into close contact with the inner circumferential surface of the container 110 due to excessive pressure.

The first, second, and third blades 272C, 274C, and 276C are coupled to the lower ends of the outer support rods 272B, 274B, and 276B, respectively. The other end of the blade support 277 is connected to the lower end of each of the outer support rods 272B, 274B, 276B in a state where the first, second and third blades 272C, 274C, 276C are coupled to one end of the blade support 277, 274B, and 276B, respectively, by being bolted to the lower ends of the outer support rods 272B, 274B, and 276B.

The shape of each of the first, second, and third blades 272C, 274C, and 276C may be different depending on whether it is in contact with the flat central region 112, . For example, when the contact area is in contact with the boundary area 114 or the sidewall area 116, the contact area is formed as a curved line. When the contact area is in contact with the flat central area 112, the contact area is formed as a straight line. This is to ensure that the ends of the first, second, and third blades 272C, 274C, and 276C are closely contacted with the inner surface (central region, boundary region, and sidewall region) of the container 110. Whether or not the first, second, and third blades 272C, 274C, and 276C are in close contact with each other is determined by stacking the first, second, and third blades 272C, 274C, 276C are tightly attached to the inner surface of the container 110 so as to stir the food.

In order to prevent the outer support rods 272B, 274B and 276B from being arbitrarily disengaged from the inner support rods 272A, 274A and 276A, that is, the outer support rods 272B, 274B and 276B are arranged on the inner support rods 272A, 274A and 276A Release preventing means may be provided at the ends of the support member 275 and the inner support rods 272A, 274A, and 276A to prevent the protrusion from occurring. The release preventing means may be formed of a locking protrusion formed in the retainer 275 and inserted into the outer support rods 272B, 274B, and 276B through the passage grooves at the ends of the inner support rods 272A, 274A, and 276A . This locking protrusion is inserted through the through groove of the retainer 275 when the inner support rods 272A, 274A and 276A are inserted into the outer support rods 272B, 274B and 276B, It is possible to prevent the outer support rods 272B, 274B, and 276B from being separated from the inner support rods 272A, 274A, and 276A by blocking the entrance of the passage groove with a stopper or the like to prevent the locking protrusion from coming out.

Meanwhile, as shown in FIG. 9, a spring 279 may be installed inside the outer support rod 274. That is, a spring may be installed between the inner support rod 272A and the outer support rod 272B to elastically support the outer support rod 272B downward. The outer support bar 272B is elastically supported in a downward direction by a spring 272C so that the outer support rod 272B can not move smoothly downward due to the resistance of food or agitated material. To the bottom of the container 110 without squeezing. At this time, although FIG. 12 is described with reference to the first stirring rod 272, the same applies to the second and third stirring rods 274 and 276.

The operation of the stirrer 200 rotating in different trajectories according to the present invention will be described.

The driving unit 240 and the rotation unit 250 of the stirrer 200 are coupled to the upper support 120 and the driven shaft 256 is projected to the bottom surface of the upper support 120, The fastening bolt is coupled to the bottom surface of the driven shaft 256 through the coupling hole formed in the center portion 261. [ In this process, the connection support member 260 is engaged with the driven shaft 256. [ At this time, the first and second and third stirring rods 272, 274 and 276 are coupled to the first, second and third corner connecting ends 262, 264 and 266 of the connection supporting member 260, And the first and second stirring rods 272, 274 and 276 are connected to the first, second and third corner connecting ends 262, 264 and 266 after the connection support member 260 is coupled to the driven shaft 256 Respectively.

When the stirrer 200 is installed in the stirring device 100, the first, second, and third blades 272C, 274C, and 276C of the stirrer 200 are in contact with the curved inner surface of the container 110 . That is, since the first stirring rod 272 coupled to the first corner coupling end 262, which maintains a horizontal state such as the horizontal line L1, maintains the vertical state directly below the blade 272C, And the second stirring rod 274 which is engaged with the second corner coupling end 264 which is upwardly bent at an angle a1 of 5 to 10 degrees with respect to the horizontal line L1, The blade 274C contacts the boundary region 114 by tilting at an angle a3 of the third corner coupling edge 266 and is coupled to the third corner coupling edge 266 that is upwardly bent at least 10 degrees with respect to the horizontal line L1, The rod 276 is brought into contact with the side wall region 116 in a state in which the rod 276 is inclined at an angle a4 larger than the second stirring rod 274 with respect to the vertical line L2.

Since the outer support rods 272B, 274B and 276B of the first, second and third stirring rods 272, 274 and 276 are coupled to the inner support rods 272A and 274A and 276A so as to move downward by their own weight, And the three blades 272C, 274C and 276C maintain a state of being in close contact with the bottom of the container 110 with a load (pressure) corresponding to the self weight of the outer support rods 272B, 274B and 276B.

The first blade 272C is in close contact with the central region 112 of the container 110 and the second blade 274C is coupled to the second corner coupling end 264 by a second stirring rod 274, Since the third blade 276C is joined to the third corner coupling end 266 and is inclined at a predetermined angle a4, (116).

Then, when the driving unit 240 is operated, the driven gear 254 engaged with the driving gear 244 rotates and rotates the connecting supporting member 260. At the same time, the driven gear 254 rotates (revolves or eccentrically rotates) the periphery of the driving gear 244 while engaged with the driving gear 244.

Therefore, the driven shaft 256 revolves at the same time as the rotation, and the connection support member 260 coupled to the lower end of the driven shaft 256 simultaneously rotates and revolves. Therefore, 272, 274, 276) rotate and revolve in different paths.

As described above, when the connection support member 260 revolves while revolving, the rotation loci of the first, second, and third stirring rods 272, 274, 276 are as shown in FIGS. Here, each of the trajectories shown in Figs. 7 to 10 represents a trajectory in which the blades 272C, 274C, and 276C move.

7, since the first stirring rod 272 coupled to the first corner coupling end 262 of the flat structure maintains a vertical state so as to be parallel to the vertical line L2, And stirs the bottom central region 112 of the container 110 while rotating and revolving with the locus as it is.

Since the second stirring rod 274 coupled to the second corner coupling end 264 bent upward at a predetermined angle is provided to be inclined at a predetermined angle with respect to the vertical line L2, The boundary region 114 of the container 110 is stirred while rotating and revolving in the same locus. That is, the second blade 274C forms a locus including a portion of the central region 112 and a portion of the sidewall region 116.

Finally, the third stirring rod 276 coupled to the third corner coupling end 266, which is upwardly bent at a larger angle than the second corner coupling edge 264, is tilted at a predetermined angle with respect to the vertical line L2 So that the sidewall region 116 of the container 110 and a part of the boundary region 114 are stirred while rotating and revolving in a locus as shown in Fig.

An inner support rod 278A having an upper end coupled to the connection support member 260 and having a first rack gear 278A-1 formed along the longitudinal direction thereof, and an inner support rod 278B having an inner support rod 278A An outer support rod 278B is formed so that a second rack gear 278C-1 is formed along the longitudinal direction and a second rack gear 278C-1 is opposed to the first rack gear 278A- A first rack gear 278A-1 and a second rack gear 278C-1 so that the outer support rod 278B is moved downward by its own weight or moved upward by an external force, 1 of the pinion gear 278D. At this time, the pinion 278D is not fixed anywhere so as to be movable up and down. Accordingly, when the coupling hole 278C and the outer support rod 278B move downward, the pinion 278D also rotates and moves downward.

Since the outer support rods 278B and the inner support rods 278A are connected by the pinions 278D engaged with the rack gears 278A-1 and 278C-1, the outer support rods 278B are connected to the inner support rods 278A It is possible to move only upward or downward with respect to the longitudinal direction.
