Since the rotation number of the garment accommodating portion 2 varies depending on the relationship between the radius of curvature R1 of the connecting portion surrounding the main pulley and the radius of curvature R2 of the connecting portion surrounding the driven pulley, The radius of curvature R1 of the connecting portion 76 and the radius of curvature R2 of the connecting portion surrounding the driven gear must be known to control the number of rotations of the garment accommodating portion 2. [

Accordingly, the present invention determines the initial position of the first operating wheel 735 and determines the distance between the first operating wheel 735 and the first fixed wheel 733, the radius of curvature R1 of the connecting portion surrounding the moving pulley, It is also possible to control the number of revolutions of the garment accommodating portion 2 through a position determiner capable of estimating at least one of the curvature radius R2 of the connecting portion surrounding the driven pulley.

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.

The initial position of the first operating wheel 735 may be set to a position at which the distance between the first operating wheel 735 and the first fixed wheel 733 becomes minimum or the position of the first operating wheel 735, The distance between the fixed wheels 733 can be set to a point where the distance becomes maximum.

The point at which the distance between the first operating wheel 735 and the first fixed wheel 733 is minimized is determined by the radius of curvature R1 of the connecting portion surrounding the main pulley being maximized and the radius of curvature of the connecting portion surrounding the driven pulley Since the number of revolutions of the driven pulley is maximized, the number of rotations of the garment accommodating portion 2 is maximized.

The point at which the distance between the first operating wheel 735 and the first fixed wheel 733 becomes maximum is that the radius of curvature R1 of the connecting portion surrounding the moving pulley is minimized and the radius of curvature of the connecting portion surrounding the driven pulley In this case, since the number of rotations of the driven pulley is minimized, the number of revolutions of the garment accommodating portion 2 becomes minimum (state of FIG. 2).

When the initial position is set to a point where the distance between the first operating wheel 735 and the first fixed wheel 733 is the maximum, the protrusion 883 corresponds to the lowest point 863b of the first gear And the contact portion 881a is provided on the circumferential surface of the first body 82 so that the lowest point 863b of the first gear is pressed by the protrusion 883 when it is located at the highest point 864a of the second gear .

Considering that the second body 85 only reciprocates linearly without rotation, it suffices that the contact portion 881a is provided at the same height as the highest point 864a of the second gear.

However, when the initial position is set to a point at which the distance between the first operating wheel 735 and the first fixed wheel 733 is minimized, the protruding portion 883 is positioned at the highest point 863a of the first gear And the contact portion 881a is provided on the protruding portion 883 when the highest point 863a of the first gear is located at the highest point 864a of the second gear, As shown in Fig.

The control unit (means for controlling the heat exchanger, the motor of the fan, the driving unit, and the motor of the speed-change drive unit) through the position determination units 881 and 883 determines whether or not the first body 82 is in the initial position can do.

The rotation angle of the first body 82, the distance between the first body 82 and the second body 85, the rotation angle of the first operation wheel 735, the rotation angle of the first body 82, The control unit (not shown) controls the time when the motor 871 of the speed change drive unit is operated after the first body 82 is moved to the initial position by changing the distance between the first fixed wheel 733 and the first fixed wheel 733 It is possible to adjust the distance between the first operating wheel 735 and the first fixed wheel 733 (radius of curvature R1 of the connecting portion surrounding the moving pulley).

The connecting portion 76 provided in the shift control portion 8 may be a ring-shaped belt that connects the driven pulleys 733 and 735 and the driven pulleys 742 and 743. [ In this case, the tension of the connection portion 76 may serve to move the distance between the first operation wheel 735 and the first fixed wheel 733 away from each other. Therefore, according to the present invention, the first body 82 is rotated in only one of the clockwise direction and the counterclockwise direction, so that the first operation wheel 735 and the first fixed wheel 733) to prevent the distance from being changed.

That is, the reverse rotation preventing portion 89 includes a fastening gear 893 (see FIG. 6) provided on the first body 82, a stopper (not shown) provided on the base 81 and coupled to the fastening gear 893 891, see FIG. 4).

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 So that it is possible to perform a cyclical linear reciprocating motion between the first operating wheels 735.

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 number of revolutions of the fan 45 is maintained during operation of the garment processing apparatus but the number of revolutions of the garment accommodating portion 2 is to be changed, the control unit must first move the first operating wheel 735 to the initial position.

In the case where the point at which the distance between the first operating wheel 735 and the first fixed wheel 733 is the maximum is set to the initial position of the first operating wheel 735 (in case of FIG. 2) The first body 82 is rotated until the lowest point 863b of the first gear reaches the highest point 864a of the second gear through the position determining portions 881 and 872 and the position determining portions 881 and 883 And rotates the first body until the highest point 863a reaches the lowest point 864b of the second gear).

Since the friction between the base 81 and the first body 82 is minimized by the protrusion 819 positioned between the base 81 and the first body 82, Will also be minimized.

When the first operating wheel 735 reaches the initial position, the reverse rotation preventing portion 89 prevents the first body 82 from rotating in the opposite direction, The motor 871 of the driving unit will be held in its position until it is operated.

When the first operating wheel 735 reaches the initial position, the rotation number of the garment accommodating portion 2 is kept at the lowest state. Therefore, after the first operating wheel 735 reaches the initial position, By controlling the operation time of the motor 871 of the speed change drive unit, the garment accommodating unit 2 can be rotated at a desired number of revolutions.

When the first body 82 continues to rotate after the first operating wheel 735 reaches the initial position, the first gear peak point 863a located at the second gear lowest point 864b is located at the second gear inclined plane The second body 85 will move in the direction away from the first body 82 since the second body 85 will move toward the second gear peak 864a along the second body 864c.

When the second body 85 moves in a direction away from the first body 82, the first operating wheel 735 moves toward the first fixed wheel 733, so that the radius of curvature of the connecting portion surrounding the moving pulley R1 ) Increases.

The second operating wheel 743 is moved in the direction away from the second fixed wheel 742 by the tension of the connecting portion 76 when the radius of curvature R1 of the connecting portion surrounding the moving pulley is increased The radius of curvature R2 of the connecting portion surrounding the driven pulley decreases. Therefore, the number of revolutions of the garment accommodating portion 2 will gradually increase.

On the other hand, since the distance between the first operating wheel 735 and the first fixed wheel 733 will be changed in proportion to the time when the main gear 873 of the speed change drive portion is rotated, The number of revolutions may be adjusted by controlling the time at which the motor 871 of the speed change drive unit is operated.

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.

However, if a rotation speed sensor for measuring the rotation speed of the garment accommodating portion 2 is provided in the garment processing apparatus 100 of the present invention, the control unit may determine that the rotation speed detected by the rotation speed sensor reaches the desired rotation speed The first body 82 may be rotated through the motor 871 of the speed-change drive unit.

While the first operating wheel 735 is moving toward the initial position, the number of rotations of the garment receiving portion 2 will gradually decrease. After the first operating wheel passes the initial position, The number will gradually increase.

Therefore, if the rotation of the first body 82 is rotated until the rotation number of the garment accommodating portion 2 sensed by the rotation speed sensor reaches a desired number of revolutions, Can be controlled.

In the above description, the garment receiving portion 2 is described as receiving power from the follower portion 74 through the receiving portion belt 7451 and the belt pulley 745, May be directly coupled to coaxial (741).

The garment accommodating portion 2 is provided on a circumferential surface of the garment accommodating portion 2 or on a rotation axis of the garment accommodating portion of the first power transmission gear fixed to the driven shaft 741 instead of the belt pulley 745 And power may be transmitted from the driven portion 74 through the second power transmission gear coupled to the first power transmission gear.

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.
