It is provided with a detergent accommodating part and a fabric softener accommodating part in which the fabric softener is accommodated.

A distribution unit is provided on the upper side of the drawer to distribute washing water to each detergent receiving space of the drawer. Washing water supply channels are connected to the rear end of the distribution unit to allow washing water to flow in.

The housing has a cylindrical shape with an upward opening. The front area of the housing is formed to be open so that the drawer can be moved forward and backward. A washing water supply pipe, one end of which is connected to the water tank, is connected to the bottom of the housing. Washing water, detergent, fabric softener, etc. are supplied into the water tank through the washing water supply pipe.

However, in this conventional clothing treatment device, the detergent that falls into the inside of the housing along with the washing water via the detergent receiving space of the drawer is not smoothly supplied to the water tank and remains inside the housing. There is a problem.

In particular, the detergent that remains inside the housing of the detergent box after contact with the washing water hardens and does not easily dissolve even when in contact with the washing water. This impedes the flow of the washing water, causing more detergent to enter the inside of the housing. This may cause it to remain in the .

Another object of the present invention is to provide a clothes treatment device and a water supply control method thereof that can control the rise of the water level inside the detergent box and suppress the generation of detergent residue due to the rise in the water level.

The laundry treatment device according to the present invention for solving the problems described above has a technical feature in that, during main washing, while washing water is supplied to the detergent box through the main passage, wash water is supplied through the free passage for a preset time. do.

More specifically, the detergent box includes a housing connected to a water tank, a drawer stored in the housing and forming a plurality of detergent accommodating spaces therein, and an upper side of the drawer to distribute washing water to the plurality of detergent accommodating spaces. It is configured to have a distribution unit that, during main washing, blocks the main flow path while supplying wash water through the main flow path, supplies wash water through the free flow path, and then supplies wash water again through the main flow path. It can be.

Accordingly, even if detergent is incorrectly added to the inside of the detergent box on the movement path of the washing water in the free flow path, the detergent is moved to the water tank by the washing water passing through the free flow path, thereby preventing the occurrence of misidentification of the position of detergent input. Detergent residue can be suppressed.

The plurality of detergent accommodating spaces inside the drawer are provided with a main detergent accommodating portion that accommodates the detergent (main detergent) used in the main laundry and a pre-detergent accommodating portion that accommodates the detergent (pre-detergent) used in the pre-washing. .

A through portion connected to the water tank is provided at the bottom of the housing, a horizontal section protrudes from the upper side of the through section inside the housing and extends in the left and right directions, and a plurality of movement paths for washing water are provided in the front area of the horizontal section. A wash water guide part is provided to guide the wash water.

As a result, during the main wash, the wash water passing through the main passage and the main detergent receiving portion moves beyond the horizontal section to the front of the horizontal section, and the remaining detergent passes through the free passage and the pre-detergent receiving section and is then washed. By being washed and removed by washing water moving along a plurality of movement paths by the water guide portion, the occurrence of detergent residue in the inner front area of the housing can be suppressed.

The wash water guide portion includes a vertical section protruding from one side of the horizontal section and disposed along the front-to-back direction of the housing; and an extension section formed in front of the vertical section to be spaced apart from the vertical section.

As a result, some of the washing water that falls into the rear area of the housing moves through between the vertical compartment and the extension compartment, and the other part moves to the front area of the extension compartment and is moved to the front area of the horizontal compartment. By forming at least two movement paths for the washing water, detergent remaining in the front area of the horizontal section is washed away, respectively, so that detergent remaining in the front area of the horizontal section inside the housing can be suppressed.

The extension section includes: a first extension section disposed on one side of the vertical section; and a second extension compartment formed on one side of the first extension compartment.

As a result, some of the washing water moved along the vertical compartment moves between the vertical compartment and the first extension compartment, and the other part moves between the first extension compartment and the second extension compartment. is moved through, and another part is moved to the front area of the second extension compartment and then moved toward the penetration part, thereby forming at least three movement paths for washing water in the front area of the horizontal compartment, The residual occurrence of detergent in the anterior region can be significantly suppressed.

More specifically, the clothing processing device includes: a cabinet; a water tank provided inside the cabinet; a detergent box connected to the water tank and supplying detergent to the water tank; A main flow path connected to the detergent box to supply washing water; A main valve provided in the main flow path; Free Euro connected to the detergent box and supplying washing water; A free valve provided in the free passage; and a first main continuous supply process of continuously supplying wash water by opening the main valve for a preset time, a free continuous supply process of continuously supplying wash water by opening the free valve for a preset time, and the main valve. A second main continuous supply process is provided for continuously supplying washing water by opening the washing water, and the washing water is supplied to the detergent box through the first main continuous supply process, the pre-continuous supply process, and the second main continuous supply process. By providing a control unit that controls each of the main valve and the free valve, generation of detergent residue inside the detergent box can be suppressed.

Here, in the first main continuous supply process, the opening time of the main valve is set to less than the first set time.

The first set time is set in consideration of the degree to which the water level inside the drawer rises because the supply speed of washing water is faster than the speed at which it is moved from the drawer due to the relatively high pressure when washing water is supplied to the inside of the drawer. It can be.

The first setting time is preferably set to 10 seconds or less.

As a result, when detergent with a smaller specific gravity than the washing water is injected into the drawer, it is possible to prevent the detergent from rising to the surface of the washing water and remaining attached to the inner wall or ceiling of the detergent box.

The control unit includes a main intermittent supply process that intermittently supplies wash water from the main flow path to the detergent box by intermittently opening and closing the main valve before the first main continuous supply process.

Here, intermittently opening and closing the main valve means repeating the operation of opening and blocking the main valve a preset number of times at relatively short time intervals.

As a result, the detergent (powder detergent) supplied inside the detergent box is released into small particles or original powder form, thereby facilitating movement by washing water and suppressing the occurrence of detergent residue inside the detergent box. You can.

In addition, when the main valve is continuously opened, the detergent inside the detergent box can be prevented from being scattered and remaining by the washing water sprayed at high pressure.

More specifically, when the washing water inside the detergent box is continuously supplied, the detergent inside the drawer is scattered and/or suspended by the washing water sprayed at high pressure and adheres to areas where the washing water is relatively difficult to access. It may remain inside the box, but when washing water is supplied intermittently, a relatively small amount of washing water first comes into contact with the detergent and wets the detergent, and this process is repeated a preset number of times to supply washing water later. Scattering and/or floating of the detergent can be suppressed, and the detergent is stably moved to the housing along with the washing water, thereby suppressing the occurrence of detergent residue inside the detergent box.

The control unit is configured to control the main valve so that the process of opening the main valve during the main intermittent opening time and blocking during the main intermittent blocking time is repeated at a preset main intermittent opening and closing frequency in the main intermittent supply process. .

The main intermittent opening time is comprised of 0.15 to 0.25 seconds, and 0.2 seconds may be preferable.

The main intermittent blocking time is 3.6 to 6 seconds, and 4.8 seconds may be preferable.

More specifically, the main intermittent opening time is 0.2 seconds, the main intermittent blocking time is 4.8 seconds, and the main intermittent opening/closing frequency is preferably 6 times.

As a result, when washing water is supplied to the main flow path, the clumped detergent among the main detergent is broken into sufficiently small particles by the intermittently supplied washing water, and the generation of detergent residue inside the detergent box caused by the clumped detergent can be suppressed. there is.

Additionally, when washing water is supplied to the main flow path, the generation of detergent residue inside the detergent box due to scattering and/or floating of detergent can be suppressed.

The control unit includes a pre-intermittent supply process that intermittently supplies wash water from the free flow path to the detergent box by intermittently opening and closing the free valve before the main intermittent supply process.

The control unit is configured to control the free valve so that the process of opening the free valve during the pre-intermittent opening time and blocking during the free intermittent blocking time is repeated at a preset number of pre-intermittent opening and closing times in the pre-intermittent supply process. .

Here, the pre-intermittent opening time can be set in the range of 0.25 to 0.35 seconds, and 0.3 seconds may be preferable.

The pre-intermittent blocking time can be set in the range of 3.92 to 5.48 seconds, and 4.7 seconds may be preferable.

As a result, when washing water is supplied to the pre-detergent, the detergent clumped in the pre-detergent is broken into sufficiently small particles by the intermittently supplied washing water to facilitate movement by the washing water, and the detergent caused by the clumped detergent is broken into sufficiently small particles by the intermittently supplied washing water. Detergent residue inside the box can be suppressed.

In addition, when washing water is supplied to the free flow, the occurrence of detergent residue inside the detergent box due to scattering and/or floating of detergent can be suppressed.

Meanwhile, in the free continuous supply process, the opening time of the free valve is set to correspond to the time when the wash water passing through the drawer is guided by the wash water guide part and reaches the penetration part.

Accordingly, in the first main continuous supply process, even if the water level inside the housing rises abnormally and detergent remains in the front area of the horizontal partition, the wash water passing through the free passage is not guided to the wash water. By being guided by the unit and moving along a plurality of washing water movement paths in the front area of the horizontal section, detergent remaining in the front area of the horizontal section can be washed and removed.

Meanwhile, a water supply control method for a clothes treatment device according to another field of the present invention includes first opening the main flow path among the main flow path and the free flow path connected to the detergent box to continuously supply wash water, and then blocking the main flow path; The technical feature is that wash water is continuously supplied by opening the free flow path, then the free flow path is blocked, and the main flow path is opened again to continuously supply wash water to the detergent box.

More specifically, the water supply control method for the laundry treatment device of the present invention includes: a cabinet; a water tank provided inside the cabinet; a detergent box connected to the water tank and supplying detergent to the water tank; a main flow path connected to the detergent box to supply wash water during main washing; A main valve provided in the main flow path; Free Euro connected to the detergent box and supplying washing water during pre-washing; and a free valve provided in the free flow passage.

By including this, the occurrence of detergent residue inside the detergent box can be suppressed.

It further includes performing a main intermittent supply process of intermittently supplying wash water from the main flow path to the detergent box by intermittently opening and closing the main valve before the first main continuous supply process.

As a result, the clumped detergent among the main detergents inside the detergent box is broken into relatively small particles to facilitate movement with the washing water, and a relatively small amount of washing water is supplied intermittently, preventing the detergent from scattering and/or floating. By suppressing this, the generation of detergent residue inside the detergent box can be suppressed.

In the step of performing the main intermittent supply process, the process of opening the main valve during the main intermittent opening time and blocking it during the main intermittent blocking time is repeated at a preset main intermittent opening and closing number.

It further includes performing a pre-intermittent supply process of intermittently supplying wash water from the free flow path to the detergent box by intermittently opening and closing the free valve before the main intermittent supply process.

As a result, the detergent that has clumped among the pre-detergents inside the detergent box is broken into relatively small particles to facilitate movement with the washing water, and a relatively small amount of washing water is supplied intermittently, preventing the detergent from scattering and/or floating. By suppressing this, the generation of detergent residue inside the detergent box can be suppressed.

In the step of performing the pre-intermittent supply process, the process of opening the free valve during the pre-intermittent opening time and blocking it during the pre-intermittent blocking time is repeated at a preset number of pre-intermittent opening and closing times.

The main intermittent opening time is smaller than the main intermittent blocking time.

The pre-intermittent opening time is smaller than the pre-intermittent blocking time.

The main intermittent opening time is smaller than the pre-intermittent opening time.

As a result, a relatively small amount of wash water is intermittently supplied to the main detergent container where the amount of detergent is relatively large, thereby reducing the possibility of the main detergent scattering and/or floating.

The pre-intermittent opening/closing frequency is greater than the main intermittent opening/closing frequency.

A preset waiting time is provided between the first main continuous supply process and the free continuous supply process and between the free continuous supply process and the second main continuous supply process.

Here, the waiting time is set in consideration of the time it takes for wash water passing through the main flow path or the free flow path to reach the penetration part via the drawer.

The fabric softener receiving portion 318 is formed on the upper side of the pre-detergent receiving portion 316. An outflow pipe 319 is formed in the fabric softener receiving portion 318 to allow the fabric softener to flow downward. The outflow pipe 319 is formed to protrude upward from the bottom surface of the pre-detergent receiving portion 316. The tubular portion 323 of the siphon forming member 321 is coupled to the outflow pipe 319. The tubular portion 323 accommodates the outflow pipe 319 therein, and a movement path through which the fabric softener can be moved is formed between the inner surface of the tubular portion 323 and the outer surface of the outflow pipe 319. . The tubular portion 323 is formed to be spaced a preset distance from the bottom of the fabric softener receiving portion 318 to allow the fabric softener to flow in. When the water level of the fabric softener in the fabric softener receiving portion 318 rises above the height of the outflow pipe 319, the fabric softener begins to flow out. When the outflow of the fabric softener begins, the fabric softener can continue to outflow even if the water level of the fabric softener becomes lower than the water level of the outflow pipe 319 due to the siphon phenomenon.

FIG. 6 is a perspective view of the housing 210 of FIG. 3, FIG. 7 is a cross-sectional view taken along line VII-VII of FIG. 6, and FIG. 8 is a cross-sectional view taken along line VIII-VIII of FIG. 6. As shown in FIGS. 6 and 7, the housing 210 has an open top and front shape. The housing 210 is disposed inside the front plate 110a of the cabinet 110. Screw fastening portions 215 are formed in the outer front area of both side portions 241 of the housing 210 so that they can be fastened with screws.

The housing 210 includes a plurality of vertical sections 220 in which the drawer 310 is stored, a horizontal section 225 formed on the lower side of the drawer 310, and a plurality of inclined sections 230. . The plurality of vertical sections 220 are disposed on both sides and the rear of the drawer 310, respectively. The horizontal section 225 and the plurality of inclined sections 230 are formed below the drawer 310, respectively.

The housing 210 includes both side portions 241 disposed on both sides of the drawer 310, a rear portion 242 disposed at the rear of the drawer 310, and a bottom portion disposed on the lower side of the drawer 310. It is provided with unit 245.

The both side parts 241 each have vertical sections 220 disposed on both sides of the drawer 310.

The rear portion 242 includes a vertical section 220 disposed behind the drawer 310.

The bottom portion 245 includes the horizontal section 225 and the plurality of inclined sections 230.

The bottom portion 245 has a penetrating portion 247 formed through it to allow the washing water inside to flow out. The penetrating portion 247 may be formed in the horizontal section 225. Here, the horizontal section 225 may be formed to be slightly inclined toward the penetrating portion 247 (for example, having a relatively small inclination compared to the inclined section 230). The plurality of inclined sections 230 may be configured to be inclined toward the penetrating portion 247. As a result, the washing water inside the housing 210 can be smoothly moved to the penetration part 247. The plurality of inclined sections 230 are not desirable because if the movement (speed) of the washing water is too slow, the transport performance of detergent is lowered, and if the movement is relatively fast, the distance passing the penetrating portion 247 increases. It may not be possible. Accordingly, the plurality of slope sections 230 are each configured to have a preset slope.

The penetrating portion 247 may be formed on one side (left side in the drawing) of the horizontal section 225. It may be formed to protrude outward from the housing 210. The other end of the washing water supply pipe 260, one end of which is connected to the water tank 140, may be connected to the penetration part 247 (see FIG. 2). As a result, the interior of the water tank 140 and the interior of the housing 210 may be communicated with each other. A washing water supply pipe connection part 251 may be formed in the penetration part 247 to allow the washing water supply pipe 260 to be connected.

A ventilation portion 450 is provided on one side of the housing 210 (for example, the left side in the drawing) so that the inside and outside of the housing 210 communicate with each other. As a result, the inside of the water tank 140 communicates with the outside of the housing 210. According to this configuration, when the door 115 is closed while an infant or animal enters the inside of the drum 160 through the front opening of the cabinet 110, the infant or animal inside the drum 160 Breathing is possible through the washing water supply pipe 260 and the ventilation unit 450.

The plurality of inclined sections 230 include a first inclined section (right inclined section) 230a and a second inclined section (left inclined section) that are formed to be inclined downwardly inward from both side portions 241 of the housing 210, respectively. ) (230b), a third inclined section (front inclined section) 230c disposed in front of the penetrating portion 247, and a fourth inclined section (rear inclined section) disposed behind the penetrating portion 247. (230d) is provided.

Here, the first inclined section 230a and the second inclined section 230b may be configured to have different inclination angles (tilts) with respect to the horizontal section 225. The first inclined section 230a and the second inclined section 230b are formed to be inclined inwardly along the left and right directions of the housing 210, respectively. The second inclined section 230b may have a larger inclination angle than the first inclined section 230a and may be configured to be relatively close to vertical. The first inclined section 230a is a section where the washing water movement path is formed and is formed at a relatively low slope. The third inclined section 230c and the fourth inclined section 230d are formed to be inclined along the front-to-back direction of the housing 210, respectively. The third inclined section 230c is formed to slope backward and downward toward the penetrating portion 247. The fourth inclined section 230d is formed to slope forward and downward toward the penetrating portion 247.

Meanwhile, the bottom portion 245 of the housing 210 allows washing water that falls to the rear of the interior along with detergent via the drawer 310 to smoothly move to the penetration portion 247 and be supplied to the water tank 140. It is structured so that it can be The bottom portion 245 of the housing 210 is provided with a plurality of inclined sections 230 to allow washing water to move at an appropriate speed.

The bottom portion 245 of the housing 210 is provided with a horizontal partition portion 272 that protrudes above the penetrating portion 247 and is disposed in the left and right directions of the housing 210. As a result, washing water that has fallen into the inner rear area of the housing 210 can be prevented from excessively moving through the penetration part 247 of the housing 210 to the inner front area of the housing 210. If the washing water moved with the detergent moves excessively to the front of the housing 210, the possibility that the detergent moved forward will remain in the front area of the housing 210 increases accordingly. More specifically, the detergent moved to the front inside of the housing 210 is relatively difficult to remove, so the possibility of it remaining increases. For example, when only the horizontal partition 272 is provided inside the housing 210, the water overflow due to an increase in the water level inside the housing 210 moves to the front of the horizontal partition 272. Washing water and detergent flow out through the penetration portion 247, but most of the detergent that has moved to the inner front area of the housing 210 along with the washing water remains in the inner front area of the housing 210. In order to eliminate this, it is necessary to form a movement path for washing water in the front area of the horizontal partition 272.

The horizontal section 272 is formed on the lower side of the ventilation portion 450. As a result, when the water level of the washing water inside the housing 210 rises, the washing water does not flow out of the housing 210 through the ventilation part 450, but flows beyond the horizontal partition 272 to the outside of the housing 210. By moving to the front area of the horizontal partition 272, excessive increase in the water level of the housing 210 can be suppressed.

The horizontal partition portion 272 is formed at a point moved a preset distance forward from the center of the penetrating portion 247 along the front-back direction of the housing 210. The amount flowing into the penetrating portion 247 may be controlled by the horizontal partition portion 272. More specifically, the horizontal dividing portion 272 may be formed at a point that divides the internal space of the penetrating portion 247 at a preset ratio (for example, approximately 70:30). As a result, most of the washing water that falls through the main detergent receiving part 314 is supplied to the water tank 140 through the rear area of the inner space of the penetrating part 247 by the horizontal partition part 272. It can be. When the water pressure of the washing water passing through the main detergent receiving part 314 increases to an abnormal, unusual level, and as a result, the flow rate increases excessively and the water level rises, the detergent exceeds the horizontal partition 272. And wash water may be moved to the front area of the horizontal section 272. Detergent and wash water moved to the front of the horizontal partition 272 can be supplied to the water tank 140 through the inner front area of the penetration part 247 disposed in front of the horizontal partition 272. there is.

The horizontal section 272 includes a first section 272a disposed above the penetrating portion 247 and a second section extending from the first section 272a to form the second inclined section 230b. It is provided with a section 272b. The first section 272a is disposed along the left and right directions of the housing 210. The second section 272b is disposed inclined backward with respect to the left and right directions of the housing 210. The second section 272b may be configured to have an inclination angle of approximately 30 to 40 degrees of the housing 210 (see FIG. 11).

The housing 210 is provided with a wash water guide unit 500 that guides the wash water so that a plurality of wash water movement paths are formed in the front area of the horizontal section 272. As a result, the detergent remaining in the front area of the horizontal partition 272 is washed away by the washing water moving along the washing water movement path formed in front of the horizontal partition 272, and the housing 210 ) can suppress detergent residue in the inner front area.

The wash water guide unit 500 is comprised of a vertical compartment 510 and a vertical compartment 510 that protrude on one side of the horizontal compartment 272 and are disposed along the front and rear directions of the housing 210. It is configured to include an extension section 520 formed at the front to be spaced apart from the vertical section 510.

The vertical partition 510 is formed to protrude upward from the first inclined section 230a. The vertical partition 510 has a substantially rectangular plate shape. The vertical partition 510 is formed to be spaced forward at a preset distance from the rear portion 242 of the housing 210. As a result, some of the washing water that falls through the pre-detergent receiving part 316 passes between the rear part 242 and the rear end of the vertical partition 510 and reaches the rear area of the horizontal partition 272. can be moved to

The extension section 520 has a substantially rectangular plate shape. The extension section 520 is formed in front of the vertical section 510 at a preset distance apart. As a result, another part of the washing water that falls through the pre-detergent receiving portion 316 moves downward between the vertical compartment 510 and the extension compartment 520. In addition, another part of the washing water that falls through the pre-detergent receiving portion 316 moves to the front of the extension section 520 and moves downward. Accordingly, the washing water that falls through the pre-detergent receiving portion 316 is moved along two movement paths to the front area of the horizontal section 272.

Some of the washing water that falls through the pre-detergent receiving part 316 moves along the vertical compartment 510, and some moves along between the vertical compartment 510 and the extension compartment 520. It moves downward to form a first movement path that moves toward the horizontal partition 272, and another part moves to the front of the housing 210 along the extension partition 520 and then moves downward to form the housing ( A second movement path is formed that moves toward the horizontal partition 272 via the front area of 210). As a result, the detergent remaining in the front area of the horizontal section 272 can be effectively washed away, thereby suppressing the detergent remaining in the inner front area of the housing 210.

The extension section 520 includes a first extension section 530 formed on one side of the vertical section 510 and a second extension section spaced apart in front of the first extension section 530. It is provided with unit 540. As a result, the washing water that falls through the pre-detergent receiving unit 316 forms a plurality of washing water movement paths in front of the horizontal section 272. As a result, the occurrence of detergent residue in the front area of the horizontal partition 272 can be suppressed.

More specifically, the first extension section 530 includes a first extension section body 532 and a first bent end portion 534 bent from the first extension section body 532. The first extension section body 532 is disposed along the front-to-back direction of the housing 210. The first bent end 534 is formed by bending the front end of the first extension section body 532. Washing water moved along the first extension section body 532 can be stably moved downward by the first bent end 534.

The second extension section 540 includes a second extension section body 542 and a second bent end portion 544 bent from the second extension section body 542. The second extension section body 542 is disposed along the front-to-back direction of the housing 210. The second bent end 544 is formed at the front end of the second extension section body 542. Washing water moved along the second extension section body 542 can be stably moved downward by the second bent end 544.

Here, the extension section 520 may be configured to have a relatively low height compared to the vertical section 510. This is because some of the washing water that falls through the pre-detergent receiving part 316 has already fallen on both sides of the vertical compartment 510, and thus the washing water is guided in a relatively small amount.

Hereinafter, the flow of washing water through the distribution unit 360 will be described with reference to FIGS. 9 to 14.

Figure 9 is a diagram for explaining the operation of the main valve supply part 391 of the distribution unit main body 362 of Figure 4, Figure 10 is a cross-sectional view taken along line X-X of Figure 9, and Figure 11 is the main valve of Figure 9. This is a diagram to explain the flow of washing water through the valve supply unit 391.

As shown in FIG. 9, when the main valve 369 is opened and the main passage 365 is opened, washing water moves to the main valve supply unit 391 and flows into the drawer 310 through the distribution hole 392. It falls into the main detergent receiving part 314.

As shown in FIG. 10, the washing water passing through the main valve supply unit 391 moves to the rear area of the main detergent receiving unit 314 of the drawer 310 and moves to the rear left side of the housing 210 in the drawing. falls into the area.

As shown in FIG. 11, the wash water that falls to the rear of the housing 210 via the main detergent receiving portion 314 of the drawer 310 flows through the fourth inclined section 230d (rear inclined section). It moves along and moves to the water tank 140 through the rear area of the penetrating part 247.

The horizontal partition 272 prevents detergent and wash water moving forward along the fourth inclined section 230d from moving to the front area of the housing 210, thereby preventing detergent from being moved to the front area of the housing 210. Suppresses residue.

Figure 12 is a diagram for explaining the operation of the free valve supply part 395 of the distribution unit main body 362 of Figure 4, Figure 13 is a cross-sectional view taken along line ⅩⅢ-ⅩⅢ of Figure 12, and Figure 14 is a free view of Figure 12. This is a diagram to explain the flow of washing water through the valve supply unit 395. As shown in FIG. 12, when the free valve 370 is opened, washing water moves along the free passage 366 and moves to the free valve supply unit 395 inside the distribution unit 360. Washing water moved to the free valve supply unit 395 falls into the interior of the drawer 310 through the distribution hole 397 on the bottom.

Washing water passing through the pre-valve supply unit 395 falls into the pre-detergent receiving unit 316 of the drawer 310. As shown in FIG. 13, the washing water that falls into the pre-detergent receiving part 316 moves to the rear area and falls into the rear area of the housing 210. Washing water that falls through the pre-detergent receiving portion 316 falls into the rear right area (first inclined section 230a) of the housing 210.

As shown in FIG. 14, some of the washing water that falls to the rear of the housing 210 via the pre-detergent receiving portion 316 is in the rear portion 242 of the housing 210 and the vertical compartment ( It moves downward through the rear end of the horizontal section 510 and moves to the rear area of the horizontal section 272. Washing water moved to the rear of the horizontal section 272 is supplied to the water tank 140 through the rear area of the penetration section 247.

Another part of the wash water that falls through the pre-detergent receiving portion 316 moves forward along the vertical compartment 510. Some of the washing water moved along the vertical compartment 510 moves downward between the vertical compartment 510 and the first extension compartment 530, and moves to the front of the horizontal compartment 272. It forms a first path (P1) that moves along the area. Another part of the wash water moved along the vertical compartment 510 is moved along the first extension compartment 530 and between the first extension compartment 530 and the second extension compartment 540. It moves downward through and forms a second path (P2) that moves through the front area compared to the first path (P1). In addition, another part of the wash water moved along the first extension compartment 530 moves downward to the front area of the second extension compartment 540, and moves downward to the front area of the housing 210, i.e. A third path (P3) is formed that passes through the front area of the second path (P2).

As a result, the detergent remaining in front of the horizontal partition 272 is washed away and removed by the washing water moved along the first path (P1), the second path (P2), and the third path (P3). , residual generation of detergent in the inner front area of the housing 210 can be suppressed. In this embodiment, the first path (P1), the second path (P2), and the third path (P3) are each shown with arrows, but the first path (P1), the second path (P2), and the third path (P3) are respectively indicated by arrows. This does not mean that the path P3 is formed to exactly match the arrow shown in the drawing.

FIG. 15 is a control block diagram of the clothing treatment device of FIG. 1. As shown in FIG. 15, the clothing treatment device according to an embodiment of the present invention includes a control unit 700 implemented with a microprocessor and a control program.

The control unit 700 performs a first main continuous supply process of continuously supplying wash water by opening the main valve 369 for a preset time, and opening the free valve 370 for a preset time to supply wash water. A pre-continuous supply process in which washing water is supplied continuously and a second main continuous supply process in which washing water is continuously supplied by opening the main valve 369, wherein the washing water is supplied in the first main continuous supply process and the pre-continuous supply process. And it is configured to control the main valve 369 and the free valve 370, respectively, so that the detergent can be supplied to the detergent box 200 through the second main continuous supply process.

An operation mode selection unit 730 capable of selecting one of a plurality of operation modes is communicatively connected to the control unit 700.

The plurality of operation modes may include, for example, a first operation mode including the main wash and the pre-wash.

The plurality of operation modes may include, for example, a second operation mode that includes the main wash and does not include the pre-wash.

The control unit 700 may perform the first main continuous supply process, the free continuous supply process, and the second main continuous supply process during the main washing in the operation mode selected by the operation mode selection unit 730. It can be configured as follows.

The main valve 369 and the free valve 370 are controllably connected to the control unit 700, respectively.

The control unit 700 is equipped with a timer 710 that counts time.

A water level detection unit 750 that detects the water level inside the water tank is communicatively connected to the control unit 700.

The first main continuous supply process may be set so that the main valve 369 is opened below the first set time. The first set time is, for example, when the pressure of the washing water is relatively high when washing water is supplied inside the drawer 310, the supply speed of the washing water is determined by the speed at which the washing water flows out from the drawer 310. It can be set in consideration of the degree to which the water level inside the drawer 310 increases faster than that of the drawer 310.

In this embodiment, the first setting time is set to 10 seconds or less, but this is only an example and is not limited thereto.

Figure 16 is a diagram for explaining the opening and closing operations of the main valve 369 and the free valve 370 of the laundry treatment device according to an embodiment of the present invention. As shown in FIG. 16, the control unit 700 operates the main valve 369 and the free valve to perform the free continuous supply process after a preset waiting time has elapsed after the end of the first main continuous supply process. It can be configured to control (370).

In addition, the control unit 700 is configured to control the main valve 369 and the free valve 370 so that the second main continuous supply process is performed after a preset waiting time has elapsed after the end of the free continuous supply process. You can.

The control unit 700 detects the water level of the water tank 140 through the water level detection unit 750 during the second main continuous supply process, and when the internal water level of the water tank 140 reaches the set water level, the main It is configured to control the main valve 369 so that the flow path 365 is blocked.

Figure 17 is a diagram for explaining a water supply control method for a clothing treatment device according to an embodiment of the present invention. As shown in FIG. 17, the water supply control method of the clothes treatment device of this embodiment includes performing a first main continuous supply process of continuously supplying washing water by opening the main valve 369 for a preset time. (S300); Performing a free continuous supply process of continuously supplying wash water by opening the free valve 370 for a preset time (S400); and performing a second main continuous supply process of continuously supplying washing water by opening the main valve 369 for a preset time (S500).

When the main wash starts, the control unit 700 controls the main valve 369 to be opened so that wash water can be supplied to the detergent box 200 through the main passage 365 (S310). The control unit 700 counts the opening time (Tmoi) of the main valve 369 through the timer 710, and when the opening time (Tmoi) of the main valve 369 reaches the set time (Tms), (S320), the main valve 369 is blocked (S330).

The control unit 700 waits for a preset waiting time after blocking the main valve 369 (S340). The control unit 700 causes the step 400 of performing the pre-continuous supply process to be performed when the waiting time has elapsed.

First, the control unit 700 opens the free valve 370 (S410). Accordingly, washing water is supplied to the detergent box 200 through the free passage 366.

Here, the washing water supplied to the detergent box 200 through the free passage 366 falls into the interior of the housing 210 via the pre-detergent receiving portion 316. At this time, if detergent is incorrectly introduced into the pre-detergent receiving portion 316 due to the user's carelessness, the pre-detergent is removed by washing water supplied to the detergent box 200 through the free passage 366. The detergent in the detergent receiving portion 316 may be moved to the water tank 140.

Washing water that falls into the housing 210 moves to the penetrating part 247 by forming a plurality of washing water movement paths in front of the horizontal partition 272 by the washing water guide part 500. do. Accordingly, the detergent remaining in the front of the horizontal section 272 is washed away by the washing water moving along the plurality of washing water movement paths, thereby generating detergent residue in the front area inside the housing 210. This can be suppressed.

The control unit 700 counts the opening time (Tfoi) of the free valve 370 by the timer 710, and when the opening time (Tfoi) of the free valve 370 reaches the set time (Tfs), (S420), the free valve 370 is controlled to be blocked (S430). When the free valve 370 is blocked, the control unit 700 waits for a preset time (S440). The control unit 700 counts the waiting time through the timer 710, and when the waiting time reaches a preset time, the control unit 700 opens the main valve 369 (S510) to open the second The main continuous supply process is performed (S500).

The control unit 700 detects the water level of the washing water inside the water tank 140 through the water level detection unit 750, and the detected water level (Lwi) inside the water tank 140 is set to the set water level (Lws). When it reaches (S520), the control unit 700 controls the main valve 369 to be blocked (S530).

FIG. 18 is a diagram for explaining the opening and closing operations of the main valve 369 and the free valve 370 of a laundry treatment device according to another embodiment of the present invention. As shown in FIG. 18, the control unit 700 of the clothing treatment apparatus of this embodiment is configured to include a main intermittent supply process, a first main continuous supply process, a free continuous supply process, and a second main continuous supply process.

The main intermittent supply process is configured to intermittently supply wash water from the main flow path 365 to the detergent box 200 by intermittently opening and closing the main valve 369 before the first main continuous supply process. .

Here, intermittently opening and closing the main valve 369 means repeating the operation of opening and blocking the main valve 369 a preset number of times at relatively short time intervals.

When washing water is intermittently supplied to the inside of the detergent box 200, the detergent (powder detergent) supplied to the main detergent receiving part 314 of the detergent box 200 is broken into small particles by the washing water. Or in its original powder form.

As a result, the movement of detergent with washing water becomes easier, thereby suppressing the occurrence of detergent residue inside the detergent box 200.

Here, if the powdered detergent agglomerates and exists in the form of a relatively large lump inside the main detergent receiving portion 314 of the detergent box 200, it cannot move along the washing water and does not move along the washing water movement path. It exists in an area that has been pushed out. The detergent clumps pushed out of the washing water movement path come into contact with the washing water and solidify, and the solidified detergent blocks the flow of washing water and detergent. This problem is solved through the main intermittent supply process and/or the pre-intermittent supply process to be described later in the clothing treatment device according to an embodiment of the present invention.

In addition, when washing water is intermittently supplied to the inside of the detergent box 200, a relatively small amount of washing water first comes into contact with the detergent (main detergent) inside the main detergent receiving portion 314. Since the detergent in contact with the washing water combines with water and relatively increases in specific gravity, scattering and/or floating when spraying the washing water can be suppressed. Here, detergent scattered and/or suspended when washing water is sprayed adheres to areas of the inner surface of the detergent box 200 that are relatively difficult to access with washing water and remains inside the detergent box 200.

In the step of performing the main intermittent supply process, the control unit 700 repeats the process of opening the main valve 369 during the main intermittent opening time and blocking it during the main intermittent blocking time at a preset main intermittent opening and closing frequency. It is composed.

The main intermittent opening time can be set to 0.15 to 0.25 seconds.

The main intermittent opening time may be preferably 0.2 seconds.

The main intermittent blocking time can be set in the range of 3.6 to 6 seconds.

The main intermittent blocking time may be preferably 4.8 seconds.

The main intermittent opening/closing frequency may be preferably 6 times.

With this configuration, the control unit 700 controls the main valve 369 to perform the main intermittent supply process during the main washing. As a result, the clumped detergent among the main detergents inside the main detergent receiving portion 314 is broken into small particles and easily moved with the washing water, thereby suppressing the generation of detergent residue inside the detergent box 200. In addition, the main detergent inside the main detergent receiving portion 314 first comes into contact with a relatively small amount of washing water, combines with the washing water, and repeats the process of suppressing scattering and/or floating a preset number of times, thereby preventing scattering. Alternatively, detergent residue inside the detergent box 200 due to floating can be suppressed.

Figure 19A is a diagram for explaining the main intermittent supply process of the water supply control method for a clothing treatment device according to another embodiment of the present invention, and Figure 19B is a diagram for explaining the main water supply control method for a clothing treatment device according to another embodiment of the present invention. This is a drawing to explain what happens after the intermittent supply process. As shown in FIGS. 19A and 19B, the water supply control method of the clothes treatment apparatus of this embodiment includes a step of performing the main intermittent supply process (S200), a step of performing the first main continuous supply process (S300), and a step of performing the first main continuous supply process (S300). A step of performing a continuous supply process (S400) and a step of performing a second main continuous supply process (S500).

In performing the main intermittent supply process (S200), the control unit 700 first opens the main valve 369 to supply washing water to the detergent box 200 through the main passage 365. Control (S210).

The control unit 700 counts the intermittent opening time (Tmioi) of the main valve 369 through the timer 710, and when the intermittent opening time (Tmioi) reaches the intermittent opening setting time (Tmios) ( S220), the control unit 700 blocks the main valve 369 (S230).

The control unit 700 counts the intermittent blocking time (Tmici) of the main valve 369 through the timer 710, and when the intermittent blocking time (Tmici) reaches the intermittent blocking setting time (Tmics) (S240) , the control unit 700 counts the number of intermittent openings and closings (number of intermittent blocking times) (Nmi) of the main valve 369 (S250).

The control unit 700 repeats the above processes until the intermittent switching frequency (Nmi) reaches the intermittent switching frequency (Nms) (S260).

In performing the main intermittent supply process (S200), the control unit 700 opens the main valve 369 for 0.3 seconds and closes it for 4.7 seconds.

More specifically, when the main valve 369 is opened, the main passage 365 is opened for 0.3 seconds, and washing water is supplied to the main detergent receiving portion 314. The washing water supplied to the main detergent receiving part 314 comes into contact with the detergent of the main detergent receiving part 314, and at this time, the clumped detergent is broken into small particles by the sprayed washing water and can be easily moved along with the washing water. It becomes a state. In addition, the detergent in contact with the washing water combines with the washing water and increases in specific gravity, so that scattering and/or floating can be suppressed. As a result, the occurrence of detergent residue inside the detergent box 200 is suppressed.

When the intermittent opening/closing frequency reaches the intermittent opening/closing set frequency (S260), the control unit 700 performs the above-described first main continuous supply process (S300), and performs the free continuous supply process (S300). The main valve 369 and the free valve 370 are controlled to perform steps S400) and performing the second main continuous supply process (S500).

As a result, the occurrence of detergent residue inside the detergent box 200 is suppressed.

Figure 20 is a diagram for explaining the opening and closing operations of the main valve 369 and the free valve 370 of a laundry treatment device according to another embodiment of the present invention. The control unit 700 of the clothing treatment apparatus of this embodiment is comprised of a pre-intermittent supply process, a main intermittent supply process, a first main continuous supply process, a free continuous supply process, and a second main continuous supply process.

The pre-intermittent supply process is configured to intermittently supply wash water from the free passage 366 to the detergent box 200 by intermittently opening and closing the free valve 370 before the main intermittent supply process.

Here, intermittently opening and closing the free valve 370 means repeating the operation of opening and blocking the free valve 370 a preset number of times at relatively short time intervals.

When washing water is intermittently supplied to the inside of the detergent box 200, the clumped detergent (powder detergent) supplied to the pre-detergent receiving part 316 inside the detergent box 200 is broken down into small pieces by the washing water. It comes in the form of granules or original powder.

As a result, the movement of detergent with washing water becomes easier, thereby suppressing the occurrence of detergent residue inside the detergent box 200.

In addition, when washing water is intermittently supplied to the inside of the detergent box 200, a relatively small amount of washing water first comes into contact with the detergent (pre-detergent) inside the pre-detergent receiving portion 316, causing the detergent to scatter and /Or floating is suppressed, and the generation of detergent residue inside the detergent box 200 is suppressed.

When performing the pre-intermittent supply process, the control unit 700 is configured to repeat the process of opening the free valve 370 during the pre-intermittent opening time and blocking it during the pre-intermittent blocking time at a preset number of pre-intermittent opening and closing times. .

The pre-intermittent opening time can be set to 0.25 to 0.35 seconds.

The pre-intermittent opening time may preferably be 0.3 seconds.

The pre-intermittent blocking time can be set in the range of 3.92 to 5.48 seconds.

The main intermittent blocking time may be preferably 4.7 seconds.

The main intermittent opening/closing frequency may be preferably 4 times.

With this configuration, the control unit 700 controls the free valve 370 to perform the pre-intermittent supply process during the main washing. As a result, detergent clumped among the pre-detergent inside the pre-detergent storage unit is broken into small particles and easily moved with the washing water, thereby suppressing the generation of detergent residue inside the detergent box 200. In addition, the pre-detergent inside the pre-detergent receiving portion 316 can be suppressed from scattering and/or floating by repeating the process of first contacting a relatively small amount of washing water a preset number of times, so that the detergent box ( 200), the occurrence of detergent residue inside can be suppressed.

Figure 21A is a diagram for explaining the pre-intermittent supply process among the water supply control method of a clothing treatment device according to another embodiment of the present invention, and Figure 21B is a water supply control method of a clothing treatment device according to another embodiment of the present invention. This is a drawing to explain the process after the pre-intermittent supply process. As shown in Figures 21A and 21B, the water supply control method of the clothes treatment apparatus of this embodiment includes a step of performing a pre-intermittent supply process (S100), a step of performing a main intermittent supply process (S200), and a first main A step of performing a continuous supply process (S300), a step of performing a pre-continuous supply process (S400), and a step of performing a second main continuous supply process (S500).

In the step of performing the pre-intermittent supply process (S100), the control unit 700 first opens the free valve 370 to supply washing water to the detergent box 200 through the free passage 366 ( S110). The intermittent opening time (Tfioi) of the free valve 370 is counted through the timer 710, and when the intermittent opening time (Tfioi) reaches the intermittent opening setting time (Tfios) (S120), the control unit 700 blocks the free valve 370 (S130). The control unit 700 counts the intermittent blocking time (Tfici) of the main valve 369 through the timer 710, and when the intermittent blocking time (Tfici) reaches the intermittent blocking setting time (Tfics) (S140) , the control unit 700 counts the number of intermittent openings and closings (number of intermittent blocking times) (Nfi) of the main valve 369 (S150).

The control unit 700 repeats the process until the intermittent switching frequency (Nfi) reaches the intermittent switching setting frequency (Nfs) and performs the pre-intermittent supply process (S160).

In performing the pre-intermittent supply process (S100), the control unit 700 opens the free valve 370 for 0.2 seconds and closes it for 4.8 seconds. The control unit 700 repeats the process of opening the free valve 370 for 0.2 seconds and blocking it for 4.8 seconds six times.

More specifically, when the free valve 370 is opened, the free passage 366 is opened for 0.2 seconds, and a relatively small amount of washing water supplied to the pre-detergent receiving part 316 is stored in the pre-detergent receiving part 316. It comes into contact with the detergent of (316). At this time, the clumped detergent among the pre-detergents is broken into small particles by the sprayed washing water and can be easily moved along with the washing water. In addition, the pre-detergent in contact with the washing water combines with the washing water and increases in specific gravity, so that scattering and/or floating can be suppressed. As a result, the occurrence of detergent residue inside the detergent box 200 is suppressed.

The control unit 700 operates the main valve ( 369).

When the main intermittent supply process is performed, the washing water passing through the main flow path 365 flows into the main detergent receiving part 314, and the detergent that has clumped in the main detergent is broken into small granules and can be easily moved by the washing water. , and the scattering and/or floating of the main detergent is suppressed through the process of supplying a relatively small amount of washing water a preset number of times (4 times). As a result, the occurrence of detergent residue inside the detergent box 200 is suppressed.

When the step (S200) of performing the main intermittent supply process is completed, the control unit 700 controls the main valve 369 to perform the step (S300) of performing the first main continuous supply process.

As the main intermittent supply process is already performed, the detergent is broken into small particles to make it easy to move, and the main detergent is supplied through the process of supplying a small amount of washing water supplied during the main intermittent opening time as many times as the main intermittent opening and closing time. Since it is in contact with and combined with washing water, the generation of detergent residue inside the detergent box 200 can be suppressed and the main detergent can be supplied smoothly during the first main continuous supply process.

When the first main continuous supply process (S300) is completed, the control unit 700 controls the free valve 370 to perform the free continuous supply process (S400). In the pre-continuous supply process, residual detergent in the front area of the horizontal partition 272 inside the housing 210, which may be generated in the first main continuous supply process, is guided by the wash water guide unit 500. It can be washed and removed by washing water moving along a plurality of washing water movement paths. As a result, the occurrence of detergent residue in the inner front area of the detergent box 200 can be suppressed.

When the step (S400) of performing the pre-continuous supply process is completed, the control unit 700 opens the main valve 369 to perform the step (S500) of performing the second main continuous supply process. The control unit 700 detects the water level of the washing water inside the water tank 140 through the water level detection unit 750 during the second main continuous supply process and detects the water level (Lwi) of the internal washing water in the water tank 140. ) opens the main valve 369 until it reaches the set water level (Lws). The control unit 700 controls the main valve 369 to block the main flow path 365 when the water level (Lwi) of the washing water reaches the set water level (Lws).
