Barrel structure for blender {BARREL STRUCTURE FOR MIXER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blender for a blender that grinds a mixed object including fruit, vegetables, and the like to produce juice.

In general, the mixer is a transmission device consisting of a container (cup) for putting the mixing object and a body in which the electric motor is accommodated.

Here, the container is made of hard heat-resistant glass, synthetic resin or stainless steel, and is mounted while the grinding blade of stainless steel is engaged on the drive portion in the lower part of the container.

In addition, as the electric motor accommodated inside the body rotates at a high speed, it has been widely used in homes for the purpose of cutting and pulverizing a mixing object including fruits and vegetables, and for producing juice of the mixing object.

However, the mixer has a limit point in which the grinding blade is rotated in one direction or rotates in one direction, but rotates in one direction for a predetermined time, thereby significantly reducing the effect of grinding and juice as the mixing object is radially pushed by the centrifugal force. have.

The present invention has been made to solve the above problems, and an object thereof is to provide a tubular structure for a mixer for improving the grinding performance of the mixing object.

Mixer cylinder structure according to an embodiment of the present invention to achieve the above object, the mixing object is accommodated, the grinding blade of the mixer is disposed therein is rotated by the drive unit of the mixer; And a protrusion formed on an inner side surface of the rotary cylinder so that the mixing object is rotated while being crushed by the grinding blade. The protrusion includes the protrusion when the grinding blade and the rotary cylinder rotate in opposite directions. It is a screw protrusion line shape to induce downward helical flow of the mixing object so that the mixing object flows downward while rotating in the opposite direction to the rotation of the grinding blade, to block the mixing object is caught between the grinding blade and the protrusion, On the lower side of the protruding portion located in the lateral direction of the grinding blade, a guide portion for sliding the mixing object to the center side of the rotating cylinder is formed.

Here, the guide portion is formed between the lower surface of the protruding portion and the inner lower surface of the rotary cylinder, and has a slide surface, wherein the slide surface extends from the inner side of the rotary cylinder to the inside of the rotary cylinder, When the grinding blade and the rotating cylinder rotate in the opposite direction may be inclined in the rotation direction of the grinding blade.

At this time, the center side edge of the rotary cylinder in the slide surface, the grinding blade and the rotary cylinder may be bent in the rotation direction of the grinding blade when rotating in the opposite direction to each other.

In addition, the slide surface may be inclined 20 degrees to 40 degrees in the rotation direction of the grinding blade on the basis of the reverse radiation direction of the rotary cylinder.

The protrusion may protrude from the inner side of the rotary cylinder toward the center of the rotary cylinder, and may be inclined in the rotation direction of the rotary cylinder when the grinding blade and the rotary cylinder rotate in opposite directions.

At this time, the protrusion may be inclined 20 degrees to 60 degrees in the rotation direction of the rotary cylinder based on the reverse radiation direction of the rotary cylinder.

In the cylindrical structure for a mixer according to the present invention, the mixing object is formed between the grinding blade and the protrusion by forming a guide portion for guiding the mixing object to the center side of the inner cylinder (rotary cylinder) at the lower side of the protrusion located in the lateral direction of the grinding blade. By blocking the catch, the rotation of the grinding blade at the beginning of the operation has the effect of preventing the stop.

In addition, in the cylinder structure for a mixer according to the present invention, the inner cylinder rotates in the opposite direction to the grinding blade by taking a structure inclined in the rotational direction of the inner cylinder while the protrusion projects from the inner side of the inner cylinder (rotary barrel) to the center side of the inner cylinder. The holding force of the protrusion for holding the mixing object becomes larger, which has the advantage of generating a greater effect of reverse rotation of the mixing object.

Referring to the drawings, the mixer according to the present invention includes a mixer body 100, the inner cylinder unit 200, and a controller (not shown).

Here, the mixer body 100 may be provided with an outer cylinder 110, a grinding blade 120 and the blade driving unit 130.

Specifically, the outer cylinder 110 is blocked to the mixing object to be accommodated therein, and the upper portion is an open upper opening structure, is configured to be opened and closed by the outer cylinder cover 140. At this time, the mixing object refers to the food to be pulverized by the operation of the blender to produce juice.

In addition, the grinding blade 120 is disposed in the outer cylinder 110, and serves to liquefy by crushing the mixing object in the outer cylinder 110 during rotation.

In addition, the blade drive unit 130 is a configuration for providing a driving force for rotating the grinding blade 120, may be provided with a first rotating shaft 131 and the first driving member (M1). At this time, the first rotating shaft 131 is connected to the grinding blade 120 in the vertical direction, the first drive member (M1) is connected to the first rotating shaft (131). That is, the first rotation shaft 131 is connected to the central portion of the grinding blade 120 disposed in the horizontal direction and arranged in the longitudinal direction, the grinding blade 120 and the first driving member (M1) by connecting the first The driving force of the driving member M1 is transmitted to the grinding blade 120 so that the grinding blade 120 may be rotated when the first driving member M1 is operated.

In addition, the inner cylinder unit 200 may include an inner cylinder 210 and an inner cylinder driving part 220.

Here, the inner cylinder 210 is disposed in the outer cylinder 110, the protrusion 211 may be formed on the inner side so that the mixing object is rotated while being crushed by the grinding blade 120.

For reference, the inner cylinder in the present specification means a rotating cylinder, the structure including the inner cylinder and the protrusions and guides described below means a cylindrical structure for a mixer.

In addition, the inner cylinder driving unit 220 is connected to the inner cylinder 210 serves to rotate the inner cylinder 210, it may be provided separately from the blade driving unit 130 for rotating the grinding blade 120.

Furthermore, although not shown in the drawings, the inner cylinder driving portion and the blade driving portion may be implemented by a single driving portion, and the driving portion may include an inner cylinder driving portion or a grinding blade that drives the inner cylinder by utilizing a driving force transfer medium such as a clutch. It can serve as a driving blade drive unit.

The controller (not shown) is electrically connected to the blade driving unit 130 and the inner cylinder driving unit 220 to control the blade driving unit 130 and the inner cylinder driving unit 220.

On the other hand, in the conventional mixer, the grinding blade is rotated in only one direction, so that the mixing object is continuously rotated in only one direction in the mixer barrel, and the mixing object is kept like a wall while being pushed out to the inner side of the mixer barrel, thereby grinding As it does not return to the blade again, the grinding performance drops significantly.

Of course, the existing mixer also has a protrusion formed on the inner wall of the mixer to create a certain amount of vortex in the mixing object, but also by implementing a flow having a regular pattern, there is a limit that the mixing object is not crushed well.

Accordingly, the mixer according to the present invention, for the irregular flow of the mixing object of the inner cylinder 210, the inner cylinder driving unit 220 so as to mix the mixing object while the controller changes the rotational direction of the inner cylinder 210 as shown in FIG. ) Can be controlled.

As a specific embodiment, the controller controls the blade driving unit (130 of FIG. 2) and the inner cylinder driving unit (220 of FIG. 2) so that the grinding blade 120 and the inner cylinder 210 is rotated in the opposite direction.

At this time, the controller repeats the on / off power to the power source of the inner cylinder drive unit 220, when the power is off, the inner cylinder 210 is inertial inertia forward rotation is linked to the rotational force of the mixing object by the grinding blade 120 Reverse the rotation.

That is, the controller controls the blade driving unit 130 and the inner cylinder driving unit 220, the power to the inner cylinder driving unit 220 in the state that the grinding blade 120 and the inner cylinder 210 is rotated in the opposite direction. Repeating the control, so that when the power of the inner cylinder driving unit 220 is turned on, the inner cylinder 210 reverse rotation (rotating in the opposite direction to the grinding blade 120), the power of the inner cylinder driving unit 220 In the off time, while the inner cylinder 210 rotates without inertia, the rotational speed gradually decreases, and is then driven by the rotational force of the mixing object by the grinding blade 120 to be rotated forward (rotate in the same direction as the grinding blade 120).

In other words, the inner cylinder 210 receives the driving force from the inner cylinder driving unit 220 only when the controller turns on the power of the inner cylinder driving unit 220, and when the controller reverses the power of the inner cylinder driving unit 220. In the inertia rotation as the driving force is not received from the inner cylinder driving unit 220 is interlocked with the rotational force of the mixing object to rotate forward.

In another embodiment, the inner cylinder driving unit 220 includes a direct current motor and a switch circuit, although not shown in the drawing, or an alternating current motor and an inverter, and the inner cylinder driving unit 220 is driven by the driving force of the inner cylinder driving unit 220 under the control of a controller. It is possible to rotate 210 forward and reverse.

That is, by utilizing the switch circuit or the inverter of the inner cylinder driving unit 220, when the inner cylinder 210 is reversely rotated as well as forward rotation by the control of the controller is provided by the driving force from the inner cylinder driving unit 220 to be driven and rotated. To be able.

As described above, the mixer according to the present invention controls the inner cylinder drive unit 220 to mix the mixing object while the controller changes the rotational direction of the inner cylinder 210, thereby breaking the balanced state of the mixing object, As it is not stacked on the inner side of the inner cylinder 210, but returns to the grinding blade 120 that rotates at the central portion of the inner cylinder 210, the grinding performance can be significantly increased.

That is, the mixer according to the present invention is configured to break the balanced state of the mixing object, and as a result of breaking down the mixing object maintained like a wall at the inner side of the inner cylinder 210, it will eventually increase the grinding performance for the mixing object. Can be.

Specifically, the mixing object is moved to the inner side of the inner cylinder 210 by the centrifugal force by the rotation of the grinding blade 120 during the mixing process, wherein the particles of the mixing object to achieve a balance (balance) of the force As it stops without moving anymore, it does not move to the grinding blade 120 side and is no longer crushed.

By the way, the balance of the force between the particles of the mixing object is broken as the rotational direction of the inner cylinder 210 in the mixer according to the present invention is changed by the imbalance of the force between the particles, the particles will flow again As it moves toward the grinding blade 120 in the flow process, the grinding is continuously made.

In addition, in the mixer according to the present invention, as shown in FIG. 5 in the condition that the grinding blade 120 is located inside the inner cylinder 210, the blade driving unit 130 and the inner cylinder driving unit 220 are the grinding blade 120. When the inner cylinder 210 and the inner cylinder 210 are rotated in opposite directions, the grinding structure of the mixing object may be further increased by the shape structure of the protrusion 211.

Specifically, the protrusion 211 may have a screw protrusion line shape to induce downward helical flow of the mixing object so that the mixing object flows downward while rotating in the opposite direction to the rotation of the grinding blade 120.

Looking specifically at the flow of the mixing object rotates in one direction by the grinding blade 120, the grinding blade 120 is disposed below the inner cylinder 210, when the grinding blade 120 rotates the mixing object is the inner cylinder ( It is pushed up to the inner side of the 210 and then raised upward along the inner side of the inner cylinder 210. Accordingly, the mixing object flowing upward while receiving the centrifugal force thus hardly flows toward the grinding blade 120 disposed on the lower side of the inner cylinder 210.

In order to flow the mixing object flowing in this way to the side of the grinding blade 120 disposed on the lower side inside the inner cylinder 210, so that the mixing object is flowed downward while rotating in the direction opposite to the rotation of the grinding blade 120, As the protrusion 211 is formed in a screw protrusion line shape, as shown in FIG. 5, downward spiral flow of the mixing object may be induced.

That is, the mixing object that is in contact with the inner side of the inner cylinder while rotating flow in one direction, by hitting the screw projection line rotates in the opposite direction and descends downward along the spiral structure of the screw projection line, to the lower side inside the inner cylinder (210) As it flows toward the side of the grinding blade 120 disposed, the grinding effect of the mixer is further increased.

Then, by comparing the blender according to the present invention configured as described above and the comparative object of the invention 1, 2, the grinding effect of the mixing object based on the grinding state for a certain time to be described with reference to Figs. do.

6 is a view showing the results of grinding the garlic as a mixing object in the blender of the present invention 1 and 2 blender of the present invention by time.

The blender according to the present invention was put into the garlic and started to pulverize, about 50% after 3 seconds, about 80% after 15 seconds, and finally about 100% was pulverized.

In comparison, the blender of Comparative Invention 1 begins to grind with garlic, and then to about 20% of the total amount of garlic, about 30% after 15 seconds, and finally about 40 minutes by 1 minute. % Was ground.

In addition, the blender of Comparative Invention 2 begins to grind garlic, and then, after about 3% of the total amount of garlic, about 30% after 15 seconds, and about 40% by 1 minute. Crushed.

7 is a view showing the results of grinding apples as a mixing object in the blender of the present invention and the blenders of the inventions 1 and 2 according to time.

After the blender according to the present invention began to grind apples, the total amount of apples was about 50% after 3 seconds, about 70% after 15 seconds, and finally about 80% by 1 minute.

In comparison, the blender of Invention 1 of the comparator 1 started to grind apples, and then, after about 3% of the total amount of apples, about 20% after 15 seconds, about 30% after 15 seconds, and finally about 40 minutes by 1 minute. % Was ground.

In addition, the blender of Comparative Invention 2 begins to grind apples, and then, after 3 seconds, about 10% after 3 seconds, about 10% after 15 seconds, and finally about 10% by 1 minute Crushed.

Finally, Figure 8 is a view showing the results of crushing the celery as a mixing object in the blender of the present invention and the blender of the inventions 1 and 2 by time.

After the blender according to the present invention was put into the celery, and pulverized, about 60% after 3 seconds, about 80% after 15 seconds, and finally about 90% was pulverized.

In comparison, the blender of Invention 1 of the present invention begins to grind with celery, and then, after about 3% of the total celery, about 5% after 15 seconds, about 10% after 15 seconds, and finally about 10 minutes % Was ground.

In addition, the blender of Comparative Invention 2 begins to grind with celery, and after about 3% of the total celery, about 5% after 3 seconds, about 10% after 15 seconds, and finally about 10% until 1 minute Crushed.

In summary, the mixers of the inventions 1 and 2 of the comparative object 1 start mixing and pulverizing the mixing object. After 3 seconds, the blender is ground in a small amount of the mixing object. Although the amount of grinding of the object is slightly increased, there is little change in the amount of grinding of the mixing object from 15 seconds to the last one minute.

This shows that the mixers of Comparative Invention 1 and 2 maintain the state in which the mixing object is no longer pulverized by keeping the mixing object in a balanced state from 15 seconds to the last minute.

That is, in the mixers of the comparative inventions 1 and 2, the mixing object is moved to the inner side of the inner cylinder by the centrifugal force caused by the rotation of the grinding blade during the mixing process, whereby the particles of the mixing object achieve a balance of power (balance). If it stops without moving any more, the grinding blade does not move to the side will no longer be pulverized.

On the contrary, after the mixer of the present invention starts to grind the mixing object and grinds it, more than half of the mixing object is pulverized after 3 seconds, and the amount of grinding of the mixing object is continuously increased even after 15 seconds, and finally, 1 minute. Even if the amount of grinding of the mixing object is steadily increased, there is a high grinding effect in which the grinding is performed in almost the amount of the mixing object.

Looking again at the configuration to implement this effect, the mixer of the present invention by controlling the inner cylinder drive unit 220 to mix the mixing object while changing the rotation direction of the inner cylinder 210, breaking the balanced state of the mixing object Accordingly, the mixing object is not stacked like a wall at the inner side of the inner cylinder 210, and back to the grinding blade 120 that rotates in the central portion of the inner cylinder 210, the grinding performance can be significantly increased.

That is, the balance of forces between the particles of the mixing object is broken as the rotational direction of the inner cylinder 210 changes in the mixer according to the present invention so that the forces between the particles are imbalanced, such that the particles flow again. As it moves toward the grinding blade 120 in the flow process, the grinding is continuously made.

The controller may control the inner cylinder driving unit 220 and the blade driving unit 130 to rotate the inner blade 210 and then rotate the grinding blade 120.

Substantially, in the mixing object rotated by the rotation of the grinding blade 120 and the inner cylinder 210, the grinding blade 120 provides a greater driving force than the inner cylinder (210).

Due to this, if the grinding blade 120 is rotated before the inner cylinder 210, the mixing object is rotated considerably faster by the grinding blade 120, even after the inner cylinder 210 rotates in the reverse direction, the mixing object is the inner cylinder (210) As the reverse rotation by) does not occur in a short time, the balanced state of the mixing object is not broken quickly.

In order to overcome these limitations, the present invention reverses the inner cylinder 210 prior to the grinding blade 120, so that the mixing object is reversely rotated at a certain speed by the rotational force of the inner cylinder 210. When the grinding blade 120 rotates at a high speed, the balanced state of the mixing object is hardly achieved, and thus the mixing object can be pulverized in a faster time.

In addition, the controller, the inner cylinder driving unit 220 and the inner cylinder 210 and the grinding blade 120 to stop at the same time at least one or more at the same time in the process of rotating the inner cylinder 210 and the grinding blade 120. The blade driving unit 130 may be controlled.

Accordingly, the mixing object rotated by the grinding blade 120 and reversely rotated by the inner cylinder 210 does not receive the instantaneous rotational force at the same time, thereby further weighting the irregular flow of the mixing object while the mixing object is momentarily decelerated. Accordingly, the effect of breaking the balanced state of the mixing object can be further increased.

On the other hand, the mixer according to the present invention, as shown in Figure 10 and 11, the guide portion 212 may be formed inside the inner cylinder (210).

In the mixer of the present invention, when the inner cylinder 210 is rotated (clockwise in the drawing) first, then the grinding blade (120 in FIG. 9) is rotated in the opposite direction to the inner cylinder 210 (counterclockwise in the drawing). In this case, the grinding blade 120 is no longer when the mixing object is caught between the grinding blade 120 and the protrusion (211 in FIG. 9) as the rotational force is considerably small before the rapid rotation is made (initial operation). It can't turn and stops.

That is, when the grinding blade 120 is blocked at the beginning of operation by the mixing object supported by the protrusion 211, the grinding object 120 is crushed and stopped by the small rotational force of the initial operation. There is a problem that is hardly made.

As an example, as shown at 10 o'clock in FIG. 9, the carrot C as a mixing object is caught between the grinding blade 120 and the protrusion 211, so that the grinding blade 120 has a blade driving part (130 in FIG. 2). Even if the driving force is continuously provided by), it can no longer rotate and stop.

In order to solve the initial operation problem of the mixer, the mixer of the present invention may be provided with an inner cylinder 210 according to another embodiment as shown in Figs.

The inner cylinder 210 may include a guide portion 212 to block the mixing object from being caught between the grinding blade (120 of FIG. 9) and the protrusion 211.

The guide portion 212 is formed on the lower side of the protrusion 211 located in the lateral direction of the grinding blade 120, and takes a structure for sliding guide the mixing object to the center side of the inner cylinder (210).

That is, the guide part 212 of the grinding blade 120 in the lower portion of the inner cylinder 210, not the upper portion of the inner cylinder 210 in order to guide the mixing object between the grinding blade 120 and the protrusion 211. It is formed laterally.

Accordingly, when the mixing object is pushed by the grinding blade 120 and moved to the protrusion 211 side, the mixing object is not caught by the protrusion 211 and meets the guide portion 212, thereby guiding the center of the inner cylinder 210 by the guide portion 212. The guide can be moved to the side.

Specifically, the guide portion 212 is formed between the lower surface of the protrusion 211 and the inner lower surface of the inner cylinder 210, and has a slide surface 212a.

At this time, the slide surface 212a extends from the inner side of the inner cylinder 210 to the center side of the inner cylinder 210, the grinding blade 120 and the inner cylinder 210 when rotating in the opposite direction to each other the grinding blade 120 Inclined in the direction of rotation.

If the slide surface 212a is inclined in the reverse rotation direction of the grinding blade 120 or the reverse radiation direction of the inner cylinder 210, not the rotation direction of the grinding blade 120, the grinding blade 120 rotates and mixing Even if the object is pushed, the mixing object is not slid from the slide surface 212a to the center side of the inner cylinder 210, and continues to be caught between the grinding blade 120 and the protrusion 211.

In consideration of this, the slide surface 212a extends from the inner side of the inner cylinder 210 toward the center side of the inner cylinder 210 and takes a structure inclined in the rotational direction of the grinding blade 120, whereby the mixing object is a grinding blade ( 120 is pushed by the slide surface (212a) when meeting the slide on the slide surface (212a) is moved to the center side of the inner cylinder (210).

In this way, the mixing object is slid by the slide surface 212a to move away from the grinding blade 120 and the protrusion 211, so that the grinding blade 120 is continuously blocked without being stopped by being blocked by the mixing object, The grinding action of the mixing object by the grinding blade 120 may be made.

At this time, the center side edge of the inner cylinder 210 in the slide surface 212a, although forming a shape that does not bend in the figure, in another preferred embodiment grinding blade 120 and the inner cylinder 210 in the opposite direction At the time of rotation may be curved in the rotational direction of the grinding blade 120.

Accordingly, the mixing object that slides on the slide surface 212a can be smoothly slid from the slide surface 212a to the center side of the inner cylinder 210 and moved to the center side of the inner cylinder 210. have.

In addition, the slide surface 212a of the guide portion 212 is preferably inclined 20 to 40 degrees in the rotational direction of the grinding blade 120 on the basis of the reverse radiation direction (arrow on the drawing) of the inner cylinder 210. Do.

If the inclination angle α of the slide surface 212a is smaller than 20 degrees, the grinding surface 120 is closer to the imaginary line in the reverse radiation direction (arrow on the drawing) of the inner cylinder 210. As the pressing direction of the mixing object and the slide surface 212a become perpendicular to each other, it becomes difficult to slide toward the center of the inner cylinder 210 on the slide surface 212a.

In addition, if the inclination angle α of the slide surface 212a is greater than 40 degrees, the guide portion 212 occupies a large amount of the inner space of the inner cylinder 210 so that the amount of the mixing object falls, eventually. The amount of mixing is also reduced.

On the other hand, the protrusion 211 is an improved embodiment, it may take a structure inclined in the rotational direction of the inner cylinder 210 while protruding from the inner side of the inner cylinder 210 toward the center side of the inner cylinder (210).

Accordingly, when the inner cylinder 210 rotates in the opposite direction to the grinding blade 120, the protruding portion 211 may have a larger holding force for holding the mixing object, thereby generating a greater effect of reverse rotation of the mixing object.

For reference, the inclined structure of the protruding portion 211 means that the surface of the protruding portion 211 located on the rotational side of the inner cylinder 210 is inclined.

Here, the protrusion 211 is preferably inclined 20 to 60 degrees in the direction of rotation of the inner cylinder 210 on the basis of the reverse radiation direction (arrow on the drawing) of the inner cylinder 210.

If the inclination angle β of the protruding portion 211 is smaller than 20 degrees, the inclined surface of the protruding portion 211 is closer to the imaginary line in the reverse radiation direction (arrow on the drawing) of the inner cylinder 210, so that the inner cylinder 210 is closed. When the protrusion 211 rotates in the opposite direction to the grinding blade 120, the holding force for holding the mixing object is weakened, so that the reverse rotation with respect to the mixing object is not sufficiently generated.

In addition, if the inclination angle β of the protrusion 211 is greater than 60, the space between the inner side of the inner cylinder 210 and the protrusion 211 decreases, so that the amount of holding of the mixing object falls, eventually mixing. The reverse rotation with respect to the object does not occur sufficiently.

Furthermore, a plurality of protrusions 211 may be formed along the inner circumferential surface of the inner cylinder 210, and as another example, as shown in FIG. 12, two protrusions 211 adjacent to each other among the plurality of protrusions 211 may be formed. The shape of the cross section may be different.

When the cross-sectional shapes of two adjacent protrusions 211 are different from each other, the vortices of the mixing object generated by the protrusions 211 also have different irregular flows, thereby increasing the grinding performance of the mixer of the present invention.

As a specific example, the protrusion 211 may have a rectangular cross-section or a curved structure as shown in the drawing.

Further, the rotation speed of the inner cylinder 210 is preferably 60rpm to 400rpm.

When the rotational speed of the inner cylinder 210 is faster than 400rpm, the grinding object of the mixer decreases due to the force of the mixing object being drawn into the inner side of the inner cylinder 210, and the mixing speed is lowered from 60rpm to 400rpm. The force that the object is attracted to the inner side of the inner cylinder 210 is greatly reduced so that the grinding performance of the mixer does not fall.

Of course, if the rotational speed of the inner cylinder 210 is slower than 60rpm, the mixing object rotates only in the direction of rotation by the grinding blade 120, and almost does not rotate in the opposite direction, so that the inner cylinder 210 becomes meaningless. .

On the other hand, the arrangement structure according to the embodiment of the blade drive unit 130 and the inner cylinder drive unit 220 described above, will be described in detail with reference to FIGS.

Both the blade driving unit 130 and the inner cylinder driving unit 220 are disposed below the inner cylinder 210, or the blade driving unit 130 is disposed below the inner cylinder 210 and the inner cylinder driving unit 220 is the inner cylinder 210. It can be disposed above the.
