Description

Clothes treating apparatus

Technical Field

The present application relates to a laundry treatment apparatus.

Background

A laundry treatment apparatus is a concept including a washing machine that separates foreign matter from an object to be washed (laundry, etc.), and a dryer that removes water from an object to be dried (wet laundry, etc.).

The existing laundry treating apparatus that can be washed is referred to as comprising: an outer tub storing water; a drum rotatably provided inside the tub and accommodating laundry; a water supply part supplying water to the outer tub; a water discharge part for discharging water stored in the outer tub; and a detergent storage part storing a detergent to be supplied to the tub.

The detergent storage part provided in the conventional laundry treating apparatus is disposed on a moving path of the water supplied from the water supply part. In the detergent storage part of the above-described structure, since the flow path provided by the water supply part is provided to connect the water supply source and the outer tub via the detergent storage part, water and detergent can be simultaneously supplied to the outer tub when the water supply part is activated.

On the other hand, a drain portion provided in an existing laundry treatment apparatus is provided to include: the drainage pump is positioned outside the outer barrel; a first drain pipe guiding water inside the outer tub to the drain pump; and a second drain pipe guiding water discharged from the drain pump to a drain port.

There are cases where it is difficult to dissolve the laundry detergent supplied to the tub in water in the laundry treatment apparatus provided with the detergent storage part and the drain part having the above-described structure.

The conventional laundry treating apparatus may rotate the drum and form a water flow inside the tub to dissolve the laundry detergent in the water, but if the water and the laundry detergent are simultaneously supplied to the tub by activating the water supply part, a portion of the laundry detergent inputted to the tub may be discharged to the first drain pipe. In this case, even if the drum rotates, the laundry detergent (the laundry detergent discharged from the outer tub) moving to the first drain pipe is difficult to flow into the outer tub again, and thus the conventional laundry treatment apparatus has a problem that the laundry detergent is difficult to dissolve in water, a problem that the laundry detergent is not washed cleanly even when a proper amount of the laundry detergent is charged (a problem that a large amount of the laundry detergent is required for washing), and the like.

If the first water supply pipe 311 is open and the second water supply pipe 312 is closed, water will be supplied only to the first chamber 511 through the first flow path 543. In contrast, if the first water supply pipe 311 is closed and the second water supply pipe 312 is open, water will be supplied only to the second chamber 512 through the second flow path 544. On the other hand, if both water supply pipes 311, 312 are simultaneously opened, water will be supplied to only the third chamber 513 through the third flow path 545.

The water supplied to each chamber 511, 512, 513 may be moved to the casing 52 through the chamber discharge ports 514, 515, 516 provided to each chamber, and the water inside the casing 52 may be moved to the outer tub main 21 through the outer tub connection pipe 32.

Fig. 4 shows an example of a control method of the laundry treating apparatus having the above-described configuration.

The control method of fig. 4 may include: a water supply step S10 of supplying only water to the tub 2; a detergent supply step S40 of simultaneously supplying detergent and water to the tub 2 after the water supply step is completed; and a washing step S80 of rotating the drum 7 and separating foreign matters from the washing object after the detergent supply step is completed.

The water supply step S10 may be performed such that the control unit (not shown) opens the tub water supply pipe 33 by controlling the tub water supply pipe valve 331 as a step of supplying water not containing the laundry detergent to the tub 2.

On the other hand, the water supply step S10 may be provided as a step of supplying water to the tub 2 through a chamber provided in the three chambers 511, 512, 513 of the detergent storage part 5, in which no detergent is stored.

That is, the water supply step S10 may be provided as a step of controlling the first and second valves 341 and 342 to supply water to the tub 2 through chambers provided in the first, second and third chambers 511, 512 and 513 of the drawer 51, in which no laundry detergent is stored.

For example, if the laundry detergent is stored in the first chamber 511, the water supply step S10 may be configured to activate the second valve 342 and supply water only to the second flow path 544, or may be configured to activate all of the first and second valves 341 and 342 and supply water only to the third flow path 545.

If the laundry detergent is stored in the second chamber 512, the water supply step S10 may be configured to activate the first valve 341 and supply water only to the first flow path 543, or may be configured to activate all of the first and second valves 341 and 342 and supply water only to the third flow path 545.

Likewise, if the laundry detergent is stored in the third chamber 513, the water supply step S10 may be configured to activate the first valve 341 and supply water only to the first flow path 543, or may be configured to activate the second valve 342 and supply water only to the second flow path 544.

The determination of which chamber stores the laundry detergent and which chamber is empty may be made based on information input by the user through the input unit 151, or may be made by a sensor provided in the laundry detergent storage unit 5 and detecting whether or not the laundry detergent is stored in each of the chambers 511, 512, 513.

The water supply step S10 is performed until the water level inside the tub 2 reaches a preset first water level (S20).

The water supply step S10 is a process for minimizing the discharge of the laundry detergent supplied through the laundry detergent supply step S40 to the first drain pipe 41 through the drain port 213 (a process of forming a water barrier at the drain port), and thus, it is preferable that the first water level is set to a water level that does not expose the drain port 213.

Fig. 5 (a) shows an example of the case where the first water level is set to be a water level L2 higher than the discharge port 213 and lower than the lowest point of the drum 7. If the heater 25 is provided inside the tub body 21, the first water level may be set to a water level L1 submerging the heater 25. Since the step of starting the heater 25 and heating the water may be started after the water supply step S10 is completed in order to promote the dissolution of the laundry detergent.

Although fig. 5 (a) shows a case where the water supply step S10 is performed through the tub water supply pipe 33, as described above, the water supply step S10 may be configured to supply water to the tub through empty chambers 511, 512, 513 of the detergent storage part 5.

Whether or not the water level inside the tub body 21 reaches the first water level is performed by the detection part 8 (S20), and if the detection part 8 detects that the water level inside the tub body 21 reaches the first water level, the water supply step is ended (S30).

As shown in fig. 4, the detergent supply step S40 may be set to start at the end of the water supply step (S30).

The detergent supply step S40 is a step of simultaneously supplying the detergent stored in the detergent storage part 5 and water to the tub body 21, and is performed so as to control the opening and closing of the storage part water supply pipes 311 and 312.

That is, the detergent supply step S40 may be provided as a step of controlling the first and second valves 341 and 342 to supply water to the chambers storing the detergent among the first, second and third chambers 511, 512 and 513 provided to the drawer 51.

For example, if the laundry detergent is stored in the first chamber 511, the laundry detergent supply step S40 is a process of activating the first valve 341 and supplying water only to the first flow path 543, if the laundry detergent is stored in the second chamber 512, the laundry detergent supply step S40 is a process of activating the second valve 342 and supplying water only to the second flow path 544, and if the laundry detergent is stored in the third chamber 513, the laundry detergent supply step S40 is a process of activating both the first valve 341 and the second valve 342 and supplying water only to the third flow path 545.

As shown in fig. 5 (b), the detergent supply step S40 may be performed until reaching a second water level L3 set to be higher than the lowest point of the drum body 71 (S50). This is to enable water inside the tub body 21 to be supplied to laundry inside the drum body 71.

The second water level may be determined according to the amount of laundry (the amount of laundry) put into the drum body 71. In this case, as shown in fig. 4, the control method may perform a laundry amount determining step S15, the laundry amount determining step S15 being performed before the start of the detergent supply step S40 and detecting the laundry amount stored in the drum 7.

The laundry amount judging step S15 may be performed in various ways. The method of determining the amount of laundry according to the amount of current supplied to the stator 741 during the period when the drum 7 is rotated to a preset reference angle, or the method of determining the amount of laundry by measuring the rotation angle of the drum after supplying a preset amount of power to the stator 741 may be exemplified. However, it is preferable that the second water level L2 is set to be increased in proportion to the amount of the washing object stored in the drum 7.

If the water level of the tub body 21 reaches the second water level L3 (S50), the detergent supply step S40 of supplying the detergent and water to the tub is ended (S60).

The washing step S80 may be set to start after the end of the detergent supply step S40. The washing step S80 may be set as a step of alternately performing clockwise rotation and counterclockwise rotation of the drum 7 by controlling the driving part 74, thereby separating foreign matter from laundry. Unlike the above, in the washing step S80, the rotation direction of the drum may be set only to the clockwise direction, or may also be set only to the counterclockwise direction.

In order to easily separate the foreign matter from the laundry, a dissolving step S70 of dissolving the laundry detergent in water may be further provided before the washing step S80 is started. The dissolving step S70 may be provided as a step of rotating the drum 7 at a lower number of revolutions than the number of revolutions set in the washing step.

In the dissolving step S70, the drum may be set to alternately perform clockwise rotation and counterclockwise rotation, or may be set to rotate in only either one of the two directions. In addition, the dissolving step S70 may be configured to activate the heater 25 to heat water while the drum is rotated.

The above-described control method can minimize the possibility that the laundry detergent supplied in the laundry detergent supply step S40 is discharged to the first drain pipe 41 through the drain port 213 by the water supply step S10, so that it is possible to prevent the laundry detergent from being insufficient to cause a decrease in washing performance.

Since the structure and control method of the laundry treating apparatus described above relate to the embodiments, the scope of the present application is not limited to the embodiments described above.
