Therefore, when the transmission control unit 8 to be described later is inserted into the pulley through hole 779, the pulley bodies 776, 777, and 778 are moved along the receiving portions 773, 774, and 775 from the main shaft 73 The diameter of the pulley will be extended since it will move in the direction of going away. As the diameter of the pulley 77 increases, the radius of curvature of the pulley 77 contacting the connecting portion 21 increases, and the increase in the radius of curvature of the pulley contacting the connecting portion increases with the increase in the number of revolutions of the garment accommodating portion 2 ≪ / RTI >

However, when the transmission control unit 8 is pulled out of the pulley through hole 779 (when the external force inputted to each pulley body disappears), the pulley bodies 776, 777, 778 are rotated by the elastic support unit, (The state shown in Fig. 4 (a)) before the shift control portion 8 is inserted into the pulley through hole 779. In this state, When the diameter of the pulley 77 in the increased diameter state is reduced, the radius of curvature of the pulley 77 contacting the connecting portion 21 also decreases, so that the number of rotations of the garment receiving portion 2 will also decrease.

2, the speed change control unit 8 includes a base 81 fixed to the second bracket 713, a first body 82 rotatably coupled to the base, A second body 85 which reciprocates between the first body 81 and the pulley 77 and a second body 85 which is inserted into the pulley through hole 779 formed in the center of the pulley 77, 855), a rotary motion of the first body is converted into a linear reciprocating motion of the second body to insert the pressing portion into the pulley through hole 779, or the pressing portion is pulled out from the pulley through hole 779 (Not shown).

5 shows a case in which the cross-sectional area of the first body guider 813 is larger than the cross-sectional area of the second body guider 815. However, the sectional area of the first body guider 813 is larger than that of the second body guider 815 It may be smaller. In any case, the first body 82 is rotatably supported, and the second body 85 is capable of implementing the base 81 that supports only the linear reciprocating motion. If the sectional area of the first body guider 813 is smaller than the sectional area of the second body guider 815, the second body guider 815 and the first body guider 813 must be detachably installed, The body 82 may be coupled to the first body guider 813.

When the highest point 863a of the first gear is in contact with the highest point 864a of the second gear in the case of the conversion unit 86 having the above-described structure, the distance between the first body 82 and the second body 85 The depth of insertion of the pressing portion 855 into the pulley through hole 779 is maximized.

In this state, when the first body 82 rotates, the first gear peak point 863a moves toward the second gear lowest point 864b along the second gear slope 864c.

The present invention minimizes the contact area between the base 81 and the first body 82 to at least one of the base 81 and the first body 82 in order to minimize the load of the speed- The protrusions may be further provided.

6 illustrates an example in which the protrusion 819 protrudes from the base 81 toward the first body 82. At least three protrusions 819 are separated from each other by the same angle, .

Further, the protrusion 819 may be formed in a columnar shape having a smaller cross-sectional area from the base 81 toward the first body 82, whereby the present invention can be applied to the base 81 and the first body 82 82 can be reduced.

The garment processing apparatus having the above-described structure can control the number of revolutions of the garment receiving portion 2 through various methods.

The apparatus for processing garments according to the present invention can control the number of revolutions of the garment receiving unit through a rotation number detecting sensor for detecting the number of revolutions of the garment receiving unit 2 in the garment processing apparatus. That is, the control unit (not shown) controls the rotation speed provided by the rotation speed detecting sensor while reducing or increasing the radius of curvature (R, see FIG. 2) of the connecting portion 21 surrounding the pulley 77 to a desired rotation speed The number of revolutions of the garment accommodating portion 2).

In addition, the garment processing apparatus of the present invention may control the number of revolutions of the garment accommodating portion 2 through a determination unit that determines whether the diameter of the pulley 77 is in a predetermined initial state. That is, the controller sets the diameter of the pulley to the initial state through the speed change drive unit 87 and then controls the operation time of the motor 871 of the speed change drive unit to increase the rotation number of the garment accommodating unit 2 to the target rotation number .

When the pulley 77 is in the initial state, the diameter of the pulley 77 changes (the diameter R of the connecting portion surrounding the pulley changes) in proportion to the operating time of the speed change drive unit motor 871, This is because the number of revolutions of the garment accommodating portion 2 will also change in proportion to the change in diameter (R, see FIG. 2).

The initial state may be set to a state where the diameter of the pulley 77 is minimum or a diameter of the pulley 77 is maximum. And examples of the determination units 881 and 883 that enable the pulley 77 to determine whether or not the pulley 77 is in the initial state.

[ In this case, the signal generating unit 881b may be configured to transmit a control signal to the control unit (not shown) whenever the contact unit 881a is pressed by the protrusion 883.

When the initial position is set to a point where the diameter of the pulley 77 is minimum, the protrusion 883 is provided on the circumferential surface of the first body 82 corresponding to the lowest point 863a of the first gear And the contact portion 881a may be configured to be pressed by the protrusion 883 when the lowest point 863a of the first gear is located at the highest point 864a of the second gear.

It is sufficient that the contact portion 881a is provided at the same height as the highest point 864a of the second gear in consideration of the fact that the second body 85 is linearly reciprocated without rotation.

When the initial position is set to a position at which the diameter of the pulley 77 is maximized, the protrusion 883 is positioned on the circumferential surface of the first body 82 corresponding to the highest point 863a of the first gear, And the contact portion 881a may be provided to be pressed by the protrusion 883 when the highest point 863a of the first gear is located at the highest point 864a of the second gear.

The connecting portion 21 connecting the pulley 77 and the garment accommodating portion 2 may be a ring-shaped belt. In this case, the tension of the connection portion 21 may serve to press the pulley bodies 776, 777, and 778 in the direction of the main coaxial shaft 73. Accordingly, the present invention can prevent reverse rotation preventing the diameter of the pulley 77 from being reduced by the connecting portion 21 by allowing the first body 82 to rotate only in a clockwise or counterclockwise direction, And the like.

The stopper 891 is a means for preventing the first body 82 from rotating in a predetermined reference direction but preventing the first body 82 from rotating in a reverse direction. Therefore, the present invention can fix the position of the first operating wheel 735 even if the motor 871 of the speed change drive unit does not arrest the first body 82 through the driven gear 873. [

As described above, the first gear 863 provided in the present invention includes a plurality of peak points 863a spaced at the same angle from each other and a plurality of lowest points 863b spaced at the same angle from each other, (864) also includes a plurality of peak points (864a) spaced at the same angle from each other and a plurality of lowest points (864b) spaced at the same angle from each other.

Therefore, even if the first body 82 rotates only in the clockwise direction or the counterclockwise direction by the anti-reverse rotation unit 89, the second body 85 can be rotated in the clockwise direction A periodic linear reciprocating motion can be performed between the pulleys 77.

Hereinafter, the operation of the present invention will be described.

When a garment is inserted into the garment accommodating portion 2, a control unit (not shown) operates the motor 61 of the driving unit to rotate the fan 45 and the main coaxial shaft 73.

A control unit (not shown) during rotation of the garment accommodating unit 2 operates the heat exchanger 33 to supply heated air to the clothes.

If the garment accommodating portion 2 rotates only in one of the clockwise direction and the counterclockwise direction, the garments inside the garment accommodating portion 2 are tangled with each other, and the tangled portion of the garment hangs for a long time There is a disadvantage. Therefore, it is preferable that the control unit alternately performs the clockwise rotation and the counterclockwise rotation of the garment accommodating portion 2.

Meanwhile, it is preferable that the rotation direction of the garment accommodating portion is changed at a time when the heat exchanger 33 is overheated and temporarily stopped operating.

The controller stops the operation of the heat exchanger (33) when the temperature of the heat exchanger (33) measured by the temperature sensor (35) reaches a predetermined first reference temperature, and the temperature measured by the temperature sensor And repeats the operation of restarting the operation of the heat exchanger 33 when the temperature reaches the second reference temperature set at a temperature lower than the reference temperature.

If the rotation direction change of the clothes accommodating portion 2 progresses while the heat exchanging portion 33 stops operating, the clothes processing apparatus of the present invention can not only prevent the clothes from being entangled but also minimize the drying time.

When the rotation speed of the fan 45 is maintained while the rotation speed of the garment accommodating portion 2 is to be changed during the operation of the garment disposal apparatus, the control unit controls the rotation speed of the pulley 45 through the speed change drive unit 87 and the determination units 881, The first body 82 is rotated until the diameter of the first body 77 reaches the initial state.

When the state shown in Fig. 9A (the state in which the diameter of the pulley is minimized) is set to the initial state, the control unit sets the lowest point of the first gear through the speed change drive unit 87 and the determination units 881 and 883 Until the uppermost point 863a of the first gear reaches the lowest point 864b of the second gear until the uppermost point 863a of the first gear 863a reaches the highest point 864a of the second gear 1 Rotate the body).

On the other hand, when the diameter of the pulley 77 reaches the initial state, the radius of curvature of the connecting portion 21 surrounding the pulley is minimized, so that the number of rotations of the garment accommodating portion 2 is also minimized.

In order to increase the number of revolutions of the garment accommodating portion 2 in such a state, the controller first rotates the first body 82 through the motor 871 and the main gear 873 of the speed change drive portion.

When the first body 82 rotates, the first gear peak point 863a located at the second gear lowest point 864b moves toward the second gear peak point 864a along the second gear slope 864c, 2 body 85 will move in a direction away from the first body 82.

When the second body 85 moves in a direction away from the first body 82, the pressing portion 855 is inserted into the pulley through hole 779 and the interval between the pulley bodies 776, 777, 778 The diameter of the pulley 77 will increase as shown in Fig. 9 (b).

As the diameter of the pulley 77 increases, the radius of curvature of the connecting portion 21 surrounding the pulley will increase, so that the number of rotations of the garment accommodating portion 2 will also increase. Therefore, the present invention can provide the clothes processing apparatus 100 capable of rotating the fan 45 and the garment accommodating portion 2 through only one driving portion 6, but controlling the number of revolutions of only the garment accommodating portion 2 have.

In this case, since the first body 82 is prevented from rotating in the reverse direction by the reverse rotation preventing portion 89, the problem that the diameter of the pulley 77 is reduced by the connecting portion 21 is prevented.

The inclination angles of the inclined surfaces 776b, 777b and 778b provided on the respective pulley bodies 776, 777 and 778 are equal to the inclination angles of the inclined surfaces 857 provided on the pressing portion, And can be smoothly inserted into the hole 779.

In order to minimize the frictional force between the pressing portion inclined surface 857 and each of the inclined surfaces 776b, 777b and 778b, any one of the inclined surfaces 857 and the inclined surfaces 776b, 777b and 778b may be provided with a roller or a ball .

The present invention may be embodied in various forms without departing from the scope of the invention. Accordingly, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
