Hereinafter, with reference to the accompanying drawings will be described in detail a clothing processing apparatus according to an embodiment of the present invention.

1 is a conceptual diagram of a laundry machine according to the present invention. Hereinafter, the overall configuration of the laundry machine will be described with reference to FIG. 1.

The laundry machine 100 of the present invention includes a cabinet 1 forming an appearance and a receiving space 2 provided to be rotatable inside the cabinet to store clothes.

The accommodation space 2 may be provided with a drum 21 for providing a space for clothes to be dried, the drum may be provided in a cylindrical shape with the front and rear surfaces open.

The front surface of the drum is provided with a front support portion 25 having an opening for receiving the door 3, the rear surface of the drum may be provided with a rear support portion 27 for supporting the rear of the drum.

The front support part 25 is provided to support the front surface of the drum, the opening portion that can accommodate the door 3 and the detachable portion 251 which is provided to be detachable to the filter assembly 5 to be described later. It is preferable to have on one side.

The rear support part 27 is provided to support the rear surface of the drum and is provided to be connected to the duct 41 of the air supply device to be described later.

Therefore, the drum is supported by the front support portion 25 and the rear support portion 27 so that the front and rear surfaces are rotatable, respectively, the drum motor 211 provided outside the drum is drum through the belt (v) The rotational force provided by the motor is provided to the drum.

In this case, it is preferable that the inner peripheral surface of the drum is further provided with a lifter 29 to facilitate the stirring of clothes.

On the other hand, the laundry machine of the present invention may further include an air supply device (4) for supplying hot air to the clothes contained in the drum.

The air supply device 4 discharges the air in the drum to the outside of the drum and resupplies the inside of the drum 21 to dehumidify and heat the air discharged from the drum. 43 and a fan 45.

 The duct 41 preferably includes an inlet port 411 communicating with the detachable part 251 provided in the front support part 25, and an outlet port 413 communicating with the rear support part 27.

That is, as shown in FIG. 1, the suction port 411 is provided to communicate with the lower portion of the detachable portion 251 so that the filter assembly 5 to be described later may be accommodated into the duct 41 through the detachable portion. The outlet 413 may be provided to communicate with a hole passing through the rear support part 27.

On the other hand, the heat exchange device 43 is preferably provided to dehumidify the air in the drum 21 discharged through the inlet 411 and heated to re-supply hot air into the drum through the outlet 413. Hida

In order to dehumidify and heat the air discharged from the drum 21, the heat exchanger 43 is provided with condensate supply means for supplying cold water into the duct to remove moisture from the air and heating means for heating the dehumidified air. Can be.

However, unlike the above, the heat exchanger 43 may be provided as a heat pump. The heat pump is a device in which an evaporator, a compressor, a condenser, and an expander are connected to a refrigerant circulation passage. The evaporator absorbs heat from the air flowing into the duct and the refrigerant evaporates, thus dehumidifying the air introduced into the duct, and the condenser supplies heat to the air flowing through the duct during the condensation of the refrigerant to circulate the duct. Heat it.

Therefore, when the heat exchanger is configured through the heat pump, a structure for communicating condensate supply means for condensing air flowing in the duct 41 to the duct is unnecessary, and a structure related to condensate treatment supplied into the duct (drainage) Since a flow path is unnecessary), a simpler air supply device can be configured.

The fan 45 is provided in the duct 41 to provide power to circulate the air in the drum along the duct.

That is, when the fan 45 rotates, the air in the duct 41 will flow into the drum through the outlet 413. When the air in the duct enters the drum, the air in the drum will open the inlet 411. It will flow into the duct 41 through. Therefore, the air inside the drum 21 will be dehumidified and heated by the heat exchanger 43 in the process of flowing inside the duct by the fan.

On the other hand, when drying the clothes inside the drum while circulating the air in the drum 21, foreign matters such as lint (Lint) may occur in the process of drying the clothes, the foreign material discharged from the clothes is a duct 41 Will cycle along.

When foreign matter such as lint is circulated through the duct 41 without being filtered, foreign matter contained in the air may be adsorbed on the surface of the heat exchanger. The drying efficiency of the result may be reduced.

Therefore, the laundry machine of the present invention may further include a filter assembly 5 for filtering foreign matters from the air circulating along the duct 41 and cleaning the filtered foreign matters so as not to lower the filtration capacity.

The filter assembly 5 may be provided to be detachably attached to the suction port 411 through the detachable part 251 of the front support part 25. In this case, the user opens the door 3 and then the filter assembly ( 5) can be separated and combined from the washing machine.

2 and 3 are perspective views of the filter assembly 5.

The filter assembly 5 is configured to be detachably attached to the inlet 411 of the duct through the detachable part 251, and a filter housing 51 for filtering air in the drum introduced into the inlet 411. And, it may include a brush unit 53 for moving the foreign matter remaining in the filter housing to one side of the filter housing and compressing.

The filter housing 51 may be attached to or detached from the inlet 411 of the duct through the detachable part 251, and the air inside the drum introduced into the inlet 411 passes through the filter housing. Is supplied.

In this case, an upper surface of the filter housing 51 may include an inflow surface 511 through which air discharged from the drum flows into the filter housing. However, it is preferable that the inflow surface 511 is provided in a shape corresponding to the detachable portion 251 to be detachable from the detachable portion, and the inflow surface includes a plurality of inflow holes 5111. desirable.

In addition, the filter housing 51 may include a filter 513 on at least one surface that filters foreign matter from the air introduced into the filter housing through the inlet hole 5111.

The filter 513 removes foreign matters from the air introduced into the filter housing, and the foreign matters may be provided in the form of a mesh to flow to the heat exchanger provided in the duct.

On the other hand, the filter is the first filter (513a) and the second filter provided in the form of a pair of nets respectively provided at opposite ends of the inlet surface 511 to maximize the filtration capacity of the filter assembly (5) ( 513b).

In this case, any one of the first filter 513a and the second filter 513b may be hinged to each other so as to be selectively separated from the inflow surface 511. This is to allow the user to remove the stored foreign matter from the filter assembly when a large amount of foreign matter is stored in the filter assembly 5.

In addition, the filter assembly 5 provided in the laundry machine of the present invention may further include a brush unit 53 for moving and compressing the foreign matter remaining in the filters 513a and 513b to one side of the filter assembly.

The brush unit 53 includes a brush 531 (FIG. 4) provided to forward and reverse rotate inside the filter assembly 5, a rotation shaft 533 which is a central axis of the forward and reverse rotation of the brush 531, and It may include a motor (not shown) that powers the brush 531.

The rotation shaft 533 is inserted into the shaft through hole 5131 (FIG. 5B) provided in the filter 513a and inserted into the shaft insertion portion 5311 of the brush 531. However, one end of the rotary shaft is located inside the filter housing 51, but is coupled to the shaft insertion portion 5311 provided in the brush 531, the other end of the rotary shaft 533 is the outside of the filter housing 51 Located in but preferably coupled to the driven gear (5331).

In this case, it is preferable that the motor further includes a main gear (not shown) engaged with the driven gear 5313. The driven shaft 533 is provided on the rotary shaft 533 and the main gear is provided to the motor indirectly to transfer the power of the motor to the brush 531 is the filter assembly 5 of the present invention detachable portion of the front support This is to be easily detached from the inlet 411 of the 251 and the duct 41.

That is, if the rotary shaft 533 is provided in a form directly connected to the motor, the filter assembly 5 is detachable to the detachable portion 251 of the front support part 25 because the motor should be directly connected to the surfaces of the filters 513a and b. In order to have a structure, a structure capable of preventing the detachable part from interfering with the motor must be provided (there is a problem that the structures of the detachable part and the suction port are complicated).

In addition, when the motor is provided on the surface of the filter, when the filter assembly is separated from the front support portion, the power supply of the motor should be provided to maintain the connection with the motor.

However, as described above, when the driven shaft 5331 is provided on the rotating shaft and the main gear (not shown) is provided on the motor, the coupling structure between the motor and the power supply of the motor can be simplified, and the structure of the detachable part and the suction port is simplified. In addition, even when the motor cannot be installed adjacent to the driven gear due to the structure of the washing machine, there is an effect of transmitting power of the motor by using the driven gear by using a plurality of gears.

Meanwhile, the brush 531 rotates forward and backward within the predetermined angle range by the rotation shaft 533 so that foreign matter remaining in the filters 513a and b is on one side of the filter assembly 5 (FIG. 4 is a lower side of the filter assembly). It is an embodiment to move to) and then press to compress the foreign matter.

The foreign matter remaining in the filter by the brush 531 is moved to one side of the filter assembly to maintain the function of the filter assembly even if the user does not clean the foreign matter remaining in the filters 513a and b. Pressurizing the foreign matter inside the filter assembly increases the frequency of operation of the washing machine, so that even if a large amount of foreign matter is stored in the filter assembly 5, the user often eliminates the inconvenience of emptying the foreign matter inside the filter assembly 5. To do so.

Meaning that the brush 531 rotates forward and backward within a predetermined angle range means that the brush repeats clockwise and counterclockwise rotation about the rotation axis 533, and in this case, the forward and reverse rotation area of the brush 531. (A, FIG. 4) preferably includes a region C (see FIG. 4) overlapping the stacked region B where foreign matter is accumulated.

On the other hand, the overlap region (C) may be implemented by appropriately designing the forward and reverse angle range of the brush.

However, since the foreign matter is stored in the filter assembly 5 therein, even if the foreign material is compressed with a brush, the foreign material will cover a part of the filter, and thus, the reduction of the filtration capacity is inevitable. Therefore, the following describes the characteristics of the filter that can minimize the reduction of the filtration capacity despite the compression storage of the foreign matter in the filter assembly.

FIG. 4 shows an embodiment regarding the shape of the filter 513 provided in the filter assembly 5.

The filters 513a and b may be provided in an asymmetrical circular shape as shown in FIG. 4 (a).

That is, the filter may be provided as a circular filter having a radius of curvature of at least two different sizes. In this case, it is preferable that the radius of curvature R of the filter formed in the direction in which the foreign matter is compressed is larger than the radius of curvature r in the direction in which the inflow surface 51 is formed.

If the radius of curvature (R) of the lower part of the filter in which the foreign matter is compressed and stored is increased, the filter capacity of the filter assembly may be minimized even if the foreign matter is compressed and stored by the brush.

On the other hand, when the filter has a polygonal shape other than an ellipse or an untagged circular shape as shown in FIG. 4 (b), the filter width w1 formed in the area B where foreign matter accumulates is the filter width w1 in which an inflow surface is formed. It may be provided to be larger than).

Since the brush 531 provided in the brush unit 53 rotates forward and backward by the rotation shaft 533, when the width of the filter is provided to be narrower from the rotation shaft 533 to the upper portion, the foreign matter is placed in the stacking area B at the bottom of the rotation shaft. Even if compressed and stored, it is possible to minimize the deterioration of the filtration capacity of the filter assembly.

On the other hand, the method of controlling the rotation direction of the motor so that the brush 531 can be rotated forward and backward within a predetermined angle range is a sensor for detecting the position of the brush and a signal from the sensor to change the rotation direction of the motor It may be implemented through a control unit (not shown), or may be implemented through a motor and a stopper to change the direction of rotation by itself when a resistance that interferes with the rotation of the brush is detected. The latter will be described below as an example.

The motor may be provided as a synchronous motor that automatically changes the rotation direction of the shaft when a resistance that interferes with rotation is detected, and the stopper contacts the brush when the brush is rotated in one direction by a predetermined angle. It can be provided to restrain the rotation of the brush.

Therefore, when the brush is rotated by the angle range set in one direction, the brush comes into contact with the stopper, and when the brush is in contact with the stopper, the motor is rotated to the set angle range by changing the rotation direction of the brush.

5 is a view of an embodiment of the stopper provided in the laundry machine according to the present invention. Hereinafter, the stopper will be described in detail.

The stopper 515 may be provided inside the filter housing 51 and may be provided with a pair of protrusions spaced apart at the same angle as a predetermined angle range set in the brush.

In this case, the stopper 515 may be provided inside the filter 513a as shown in FIG. 5 (a), or may be provided outside the filter 513a as shown in FIG. 5 (b). have.

FIG. 5C illustrates a case in which one stopper 5133 is provided in the filter 513a. In this case, the brush 531 includes a stopper accommodating groove 5313 for accommodating the stopper 5133. Is provided.

That is, the stopper 5133 illustrated in FIG. 5C is provided at one side of the outer circumferential surface of the shaft through hole 5131 provided in the filter 513a so that the rotation shaft 533 penetrates, and the stopper receiving groove 5313 is The rotating shaft 533 is provided in the shaft insertion portion 5311 is accommodated.

In this case, the stopper accommodating groove 5313 may be bent at an outer circumferential surface of the shaft insertion part 5311 to be in contact with the stopper 5133 when the brush is rotated by a predetermined angle.
