Referring to FIG. 6, the clothes treating apparatus includes a cabinet 10 that forms an exterior, a tub 20 that is provided inside the cabinet 10 to accommodate laundry water, and a rotatable inside the tub 20 that is laundry. The drum 30, which accommodates the water, is detachably provided inside the drum 30, and the first drain draining the washing water discharged from the auxiliary container 40 and the auxiliary container 40, in which washing of laundry is performed separately from the drum. A flow passage 36 and a second drain passage 38 are included. Here, the first drum 30 and the second drum of the laundry treatment apparatus according to the embodiment are named as the drum 30 and the auxiliary container 40, respectively.

The cabinet 10 may include a cabinet opening 11 and a door 13 that opens and closes the cabinet opening 11 on one surface thereof to allow the laundry to be pulled out or pulled out.

The upper side of the tub 20 is connected to a water supply device for supplying wash water into the tub.

The water supply device is a water supply valve 54 for controlling the amount of wash water supplied from an external water supply source, one end of which is connected to an external water supply source and the other end of which is connected to a water supply valve to wash water from an external water supply source to a water supply valve. The first water supply pipe 55 to be drawn in and one end of the water supply valve 54 and the other end are formed to face the tub 20 to include a second water supply pipe 56 for supplying the wash water to the tub 20.

The lower side of the tub 20 is connected to the drainage for draining the wash water.

Drainage device is a drain pump 65 for providing power for discharging the wash water contained in the tub 20, one end is connected to the tub 20 and the other end is connected to the drain pump 65 to wash the tub 20 A first drain pipe 66 for introducing water to the drain pump 65 and one end thereof are connected to the drain pump 65 and the other end is exposed to the outside to discharge the wash water from the drain pump 65 to the outside of the cabinet 10. And a second drain pipe 67. The first drain pipe 66 may be formed of a bellows pipe so that vibration of the tub 20 is not transmitted to the drain pump 65.

The tub 20 is circumferentially supported by the vibrator 70 to be fully cushioned. The vibrator 70 is provided on the lower side of the tub 20, and is formed of a damper 77 connected to the spring 75 and the spring 75 in series and provided above the spring. However, in FIG. 6, the spring 75 and the damper 77 are provided at the lower side of the tub 20 to be connected in series, but this is only an example, and the spring 75 is connected to the upper side of the tub 20. It may be configured in various ways.

On the other hand, the tub 20 includes a tub cover 25 detachably coupled to the upper end of the tub 20.

The tub cover 25 is detachably provided at the upper end of the tub 20 and extends inwardly of the tub 20 from the cover bent portion 25b and the cover bent portion 25b that are bent into the tub 20. And a cover horizontal portion 25a having an opening formed in the center thereof. The user may inject laundry through the opening formed in the center or attach or detach the auxiliary container 40 to the inside of the drum 30.

On the other hand, the first drain passage 36 is formed of a space formed as the tub cover 25 and the balancer 37 are spaced apart from each other. As described below, the first drain passage 36 serves to drain the wash water discharged from the auxiliary container 40 to the tub 20.

The second drain passage 38 is formed between the drum 30 and the auxiliary container 40 and serves to drain the wash water to the drum 30. Hereinafter, the second drain passage 38 will be described with reference to FIG. 7. FIG. 7 is a plan view for describing the second drain passage 38 illustrated in FIG. 6.

Referring to FIG. 7, the second drain passage 38 is formed by recessing a portion of the inner circumferential surface of the upper end of the drum 30 and extends downward of the drum 30. When the balancer 37 is provided at the upper end of the drum 30, the second drain passage 38 is formed by recessing a portion of the inner circumferential surface of the balancer 37. The second drain passage 38 serves to drain the wash water discharged from the auxiliary container 40 to the drum 30 as described below.

In particular, when the balancer 37 is a ball balancer operated by the ball, the recessed depth of a part of the inner circumference should be adjusted so that the ball can move smoothly inside the balancer 37.

On the other hand, when the auxiliary container 40 is rotated at a very high rotational speed to reach the dehydration step, the washing water discharged from the auxiliary container 40 may be discharged to a part of the upper portion. Scattered wash water may move to the outside of the tub 20 to cause various problems such as corrosion of parts and failure of electrical appliances.

Accordingly, the clothes treating apparatus may further include scattering prevention parts 22 and 26 formed to prevent the washing water discharged from the auxiliary container 40 from scattering upward.

In addition, it may further include a scattering recovery unit 23, 27 for recovering the wash water is blocked by the scattering prevention unit 22, 26 to guide to the second drain passage (38).

The scattering prevention parts 22 and 26 and the scattering recovery parts 23 and 27 may be formed according to various embodiments. Hereinafter, the scattering preventing unit 22 provided in the tub cover 25 will be described with reference to FIGS. 8 and 9.

FIG. 8 is an enlarged view of a portion A of FIG. 6, and FIG. 9 is a diagram illustrating another embodiment of a scattering prevention unit and a scattering recovery unit.

Referring to FIG. 8, the scattering prevention part 22 according to an example includes a curved surface extending from the inner surface of the tub cover 25 toward the auxiliary container 40 but formed to be convex upward. Accordingly, the wash water discharged from the auxiliary container 40 is prevented from being scattered to the outside of the tub 20 as it collides with the lower surface of the shatterproof part 22.

Meanwhile, the scattering recovery unit 23 according to an example is provided on the lower surface of the scattering prevention unit 22 to guide the wash water collected on the lower surface to the second drain passage 38. Specifically, the scattering recovery portion 23 is formed to extend downward from the lower surface of the scattering prevention portion 22, one side is formed to face the auxiliary container (40). For example, it may be formed of a rib that protrudes from the lower surface of the shatterproof portion 22 and extends in the circumferential direction of the tub cover 25.

The scattering prevention unit 22 prevents the washing water from scattering by colliding with the wash water, and the scattering recovery unit 23 guides the seta water collected in the scattering prevention unit 22 to the second drain passage 38. However, this explains the main function. In fact, the present invention is not limited to the main function, and the scattering water recovery unit 23 may also prevent the washing water from scattering due to a collision with the washing water, and the scattering preventing unit 22 may also wash the water into the second drain passage 38. I can guide you.

Referring to FIG. 9, the shatterproof part 26 according to another example is formed of a flat surface rather than a curved surface. In detail, the tub cover 25 includes a blocking horizontal portion 26a extending horizontally from the tub cover 25 and a blocking inclined portion 26b extending downward from the blocking horizontal portion 26a toward the auxiliary container 40.

The scattering recovery part 26 according to another example is provided on the lower surface of the blocking slope part 26b but is formed to maintain a predetermined angle θ and a direction in which gravity acts. The predetermined angle θ is set such that the scattering water recovery unit 27 guides the washing water to the second drain passage 38 more smoothly.

Referring back to FIG. 6, the auxiliary container 40 is detachably coupled to the inner circumferential surface of the upper end of the drum 30 and is detachably attached to the auxiliary body 48 and the auxiliary body 48 for receiving laundry and washing water. And it includes an auxiliary cover 46 that is formed with a fine water inlet for injecting laundry.

The auxiliary container 40 is detachably coupled to the upper end of the balancer 37 inner circumferential surface, and more specifically, the upper end of the auxiliary body 48 is coupled to the inner circumferential surface of the balancer 37 of the drum 30. If the auxiliary cover 46 is coupled to the balancer 37 inner circumferential surface, it is difficult to maintain a firm coupling between the auxiliary cover 46 and the auxiliary body 48 due to the weight of the wash water accommodated in the auxiliary body (48).

The upper end of the auxiliary container 40 includes a coupling part C1 coupled to the inner circumferential surface of the balancer 37 and a spaced part C2 spaced apart from the balancer 37. However, in the present specification, the coupling part C1 and the separation part C2 are not limited to the upper end of the auxiliary container 40. This is because the auxiliary container 40 is constant in both cross sections from the upper end to the lower end. Therefore, in the present specification, the coupling part C1 is a concept including both the upper and lower parts of the part indicated by C1 of FIG. 7, and the separation part C2 is used as the concept including both the upper and lower parts of the part indicated by C2 of FIG. 7. do. Therefore, in the present specification, both the auxiliary cover 46 and the auxiliary body include a coupling part C1 and a spacer part C2. Meanwhile, in FIG. 7, the coupling part C1 is displayed only on one side of the auxiliary container, but for convenience of drawing. Therefore, the coupling part C1 is composed of a pair of coupling parts C1 provided on opposite sides, and the spaced part C2 is also the same.

Meanwhile, the spacer C2 is illustrated as a plane in FIG. 7 but is not limited thereto. In other words, the separation part C2 may be formed in a curved surface, and thus the cross section of the auxiliary container 40 may be formed in an oval shape as a whole. Accordingly, the coupling part C1 may be a first curvature part C1 having a first curvature, and the separation part C2 may be a second curvature part C2 having a second curvature smaller than the first curvature.

Meanwhile, the first curvature portion C1 may be referred to as the remote portion C1, and the second curvature portion C2 may be referred to as the short distance portion C2.

According to the above configuration, the auxiliary container 40 can raise the washing force by causing the vortex of the wash water.

The auxiliary cover 46 includes a drainage portion of the auxiliary container 40 according to various embodiments of draining the wash water by centrifugal force by the rotation of the auxiliary container 40. The auxiliary vessel drainage portion 41, that is, the second drum drainage portion 41 of FIG. 8, will not be described in order to avoid redundant description.

Hereinafter, the auxiliary container drainage unit according to various embodiments will be described with reference to FIGS. 10 to 13. 10 to 13 is a view showing various embodiments of the auxiliary container drain.

Referring to Figure 10, the auxiliary container drainage portion 46 according to another embodiment of the present invention is formed in the auxiliary cover 46, the discharge portion 943 and to discharge the washing water accommodated in the auxiliary body 48 to the top and It is formed on the auxiliary cover 46, and includes a decompression unit for reducing the washing water before being discharged by the discharge unit (943).

The discharge part 943 is provided above the decompression unit and is formed in the shape of a discharge hole formed in the circumferential surface of the upper end of the auxiliary body 48. Discharge part 943 is provided in the coupling portion (C1), that is, the remote portion (C1) that the centrifugal force by the rotation of the auxiliary container 40 is the largest. Washing water at the same rotational speed can be more easily discharged because it rises the highest along the inner peripheral surface of the coupling portion (C1).

The decompression unit is provided under the discharge unit 943 to depressurize the washing water rising along the inner circumferential surface of the coupling unit C1. That is, the decompression unit acts as a resistance to the wash water to hinder the flow of the wash water, so that the wash water contained in the auxiliary container 40 rotating at a constant rotational speed cannot be easily discharged from the auxiliary container.

For example, when the auxiliary container 40 rotates at a rotational speed to perform the washing stroke, the washing water is not discharged from the auxiliary container 40. This is because, even when the auxiliary container 40 performs the washing stroke, when the washing water is discharged to the outside through the discharge part 943 along the inner circumferential surface, the washing stroke may no longer be performed. Therefore, the decompression unit may not discharge the washing water at a rotational speed at which the washing stroke is performed as the water pressure of the washing water rising along the inner circumferential surface of the auxiliary body 48 may be discharged at the rotational speed at which the dewatering stroke is performed. So that it is formed.

As shown in FIG. 10, the decompression unit includes a rising passage 941 for raising the washing water and a falling passage 942 for lowering the raised washing water. Specifically, the up flow passage 941 and the down flow passage 942 are provided in a space formed between the circumferential surface of the auxiliary cover 46 and the cover protrusion 945 extending downward from the lower surface of the auxiliary cover 46. It is formed by a water wall extending upwardly. Therefore, one side of the water wall forms one side of the upward flow path and the other surface forms one side of the downward flow path 942.

The washing water rises along the up flow passage 941 and then is bent to decrease the water pressure while descending along the down flow passage 942. In other words, the up flow passage 941 and the down flow passage 942 act as resistances to prevent the washing water from moving smoothly.

On the other hand, the down flow passage 942 may be formed narrower than the up flow passage (941) in order to further reduce the pressure of the wash water. In addition, the upward passage 941 and the downward passage 942 may be formed such that the cross-sectional area of the passage gradually decreases along the direction in which the wash water moves.

The discharge part 943 may be discharged to the outside while the wash water is moved along the down flow passage 942 as the discharge portion 943 is formed to communicate with the down flow passage 942 on the other side of the down flow passage 942.

Referring to FIG. 11, the auxiliary container drain 48 according to another embodiment of the present invention is configured to reduce the pressure of the auxiliary container 40 according to another embodiment shown in FIG. 10. There is a tooth point in which the ascending passage is provided with a plurality of collectors and through holes for communicating the plurality of collectors. Due to this difference, the water pressure decreases more as the wash water passes through the upward flow passage 481. This difference is described below.

In detail, the upward flow path 481 includes a lower collecting part 486 provided under the rising flow path 481, an upper collecting part 487 provided at an upper part of the rising flow path 481, and a lower collecting part 486. The third through hole (481a), the second through hole (481b) for communicating the lower collecting portion 486 and the upper collecting portion (487), the upper collecting portion (487) and the down flow passage to communicate with The through hole 481c is provided.

The wash water is sequentially formed through the first through hole 481a, the lower collecting part 486, the second through hole 481b, the upper collecting part 487, and the third through hole 481c provided in the upward flow passage 481. After passing through, it enters the descending flow path.

The first through hole 481a and the second through hole 481b are provided at different hardnesses to reduce the pressure of the wash water while the washing water passes through the rising passage 481, and the second through hole 481b and the first through hole 481b are provided at different hardnesses. The three through holes 481c are provided on different hardnesses. The first through hole 481a and the third through hole 481c are provided on the same hardness or on different hardnesses.

In addition, the upper collecting portion 487 is formed to have a smaller volume than the lower collecting portion 486 can reduce the washing water more effectively.

Although the above-described decompression unit is illustrated only for the lower collector 486 and the upper collector 487 in FIG. 11, this is only an example, and a plurality of collectors may be additionally provided below the lower collector 486. And a plurality of collectors in addition to the upper side of the upper collector 487 may be provided. In addition, unlike the illustrated in FIG. 11, the decompression unit may include a single lower collector 486 and a plurality of upper collectors 487 arranged side by side along the circumferential direction, or vice versa.

On the other hand, the decompression unit of the auxiliary container drainage unit 48 according to the present embodiment should rotate the auxiliary container 40 at the first RPM in order to draw the wash water contained in the auxiliary container 40 to the lower collection 486.

In addition, the decompression unit of the auxiliary container drainage unit 48 according to the present embodiment should rotate the auxiliary container 40 at the second RPM in order for the wash water accommodated in the auxiliary container 40 to be drawn into the upper collecting part 487.

The first RPM is 60 rpm to 100 rpm, more specifically may be set to 80 rpm to 100 rpm.

The second RPM is 100 rpm to 150 rpm, more specifically, may be set to 100 rpm to 120 rpm.

On the other hand, among the washing water collected in the lower collecting unit 486 by the simple dehydration performed during the washing or rinsing stroke, the washing water that has not moved to the upper collecting unit 487 is an auxiliary container even at a rotation speed lower than the first rpm. By the centrifugal force by the rotation of the upper collecting portion 487 can be moved.

Referring to FIG. 12, the auxiliary container draining portion 91 according to another embodiment of the present invention has no pressure reducing portion, and has a discharge portion 911 and a discharge portion 911 formed of discharge holes formed on the circumferential surface of the auxiliary cover 46. The second drainage flow path 38 is provided on the upper side of the secondary scattering prevention portion 912 and the scattering water collected on the lower surface of the secondary scattering prevention portion 912 to prevent the washing water discharged from the discharge portion 911 upwards 38 It includes an auxiliary scatter recovery unit 913 to guide.

The auxiliary scatter prevention unit 912 may be formed to be inclined upward toward the outside of the auxiliary cover 46. However, this is merely an example and may be formed in various forms such as a lower surface formed horizontally.

The lower surface of the auxiliary scatter prevention unit 912 is provided with a secondary scattering recovery portion 913 for collecting the scattered water collected on the lower surface to guide to the second drain passage (38). The auxiliary scatter recovery portion 913 is provided on the lower surface of the auxiliary scatter prevention portion 912 and includes at least one rib extending downward. In FIG. 12, the rib constituting the auxiliary scatter recovery portion 913 extends downward along the gravity direction, but is not limited thereto, and the auxiliary rib may be configured in consideration of the size of the auxiliary scatter prevention portion 912 and the position of the second drain passage 38. It may be formed to be inclined downward toward the outside or the inside of the cover 46.

Referring to FIG. 13, the auxiliary container drainage part 93 according to another embodiment of the present invention includes an auxiliary ratio provided at an upper portion of the nozzle part 931 and the nozzle part 931 formed on the circumferential surface of the auxiliary cover 46. The acid prevention part 912 and the inclination part 935 provided under the nozzle part 931 are included.

The nozzle part 931 is provided to be higher than the upper end of the balancer 37 and lower than the cover horizontal part 25a, and at least one formed to penetrate the upper end of the auxiliary container 40, that is, the circumferential surface of the auxiliary cover 46. It consists of discharge holes. The nozzle part 931 is used for spraying the washing water far to a desired point.

In detail, the nozzle part 931 is formed at the other side to discharge the washing water introduced through the nozzle inlet 931a and the nozzle inlet 931a to allow the washing water to flow in, and is formed to be smaller than the inlet. It includes. Accordingly, the nozzle part 931 may move the washing water to a relatively far place, and in this embodiment, the nozzle part 931 is located far from the auxiliary container 40 instead of the second drain passage 38. It is used for the purpose of discharging to the first drain passage (36).

Specifically, the nozzle portion 931 is provided on the circumferential surface of the auxiliary cover 46, and the inclination angle is adjusted to discharge the washing water toward the inner surface of the tub cover 25. In detail, the nozzle part 931 is adjusted so that the washing water is discharged toward the lower surface of the cover horizontal part 25a.

In particular, the discharge angle of the washing water discharged from the nozzle part 931 is adjusted so that the incident angle of the washing water with respect to the lower surface of the cover horizontal portion 25a becomes an acute angle. Accordingly, since the amount of washing water is small due to the collision with the lower surface when the washing water enters the lower surface of the cover horizontal portion 25a, most of the washing water is guided to the tub 20 along the first drain passage 36. Can be.
