Laundry may pass through the laundry inlet (11), the tub opening (21) and the drum opening (31) in sequence to be accommodated inside the drum (30) or taken out from the drum (30). The drum opening (31) may be provided to face approximately forward.

[0084] The drum (30) can perform each operation according to the washing, rinsing, and / or dehydration process while rotating inside the tub (20). A plurality of holes (32) are formed in the cylindrical wall of the drum (30), so that water stored in the tub (20) can flow into the inside of the drum (30) or flow out from the outside of the drum (30).

[0085] The garment treatment device (1) may include a driving device (36) configured to rotate a drum (30). The driving device (36) may include a driving motor and a rotating shaft for transmitting driving force generated by the driving motor to the drum (30).

[0087] The clothing treatment device (1) may include a water supply device (40). The water supply device (40) may include water supply valves (41, 42) that can be connected to an external water source. For example, the water supply valves (41, 42) may include a first water supply valve (41) for supplying hot water and a second water supply valve (42) for supplying cold water. The first water supply valve (41) may be referred to as a hot water valve. The second water supply valve (42) may be referred to as a cold water valve.

[0088] The water supply device (40) may include a water supply valve (41, 42) and a water supply pipe (43, 44). The water supply pipe (43, 44) may be provided as a flexible material hose, a plastic pipe, or a metal pipe. The water supply pipe (43, 44) may be connected to the water supply valve (41, 42). For example, the water supply pipe (43, 44) may include a first water supply pipe (43) connected to a first water supply valve (41), and a second water supply pipe (44) connected to a second water supply valve (42). The first water supply pipe (43) may be referred to as a hot water pipe. The second water supply pipe (44) may be referred to as a cold water pipe.

[0089] At least one of the water supply pipes (43, 44) can guide water from the water supply valve (41, 42) to the tub (20). For example, at least one of the water supply pipes (43, 44) can extend from the water supply valve (42) to the tub (20). For example, the water supply pipe (43, 44) that is provided to extend from the water supply valve (42) to the tub (20) can be referred to as a direct water supply pipe. The water supply pipe (43, 44) that is provided to extend from the water supply valve (42) to the tub (20) can be provided to supply water by being connected to a diaphragm (22) described later. A specific description of the water supply pipe (43, 44) that is provided to extend from the water supply valve (42) to the tub (20) will be described later.

[0090] Water can be supplied to the lower detergent supply device (60) via the tub (20). For example, water can be supplied to the lower detergent supply device (60) without passing through the tub (20).

[0091] The water supply valves (41, 42) can open or close the water supply pipes (43, 44). The water supply valves (41, 42) can allow or block the supply of water from an external water source to the tub (20). For example, the water supply valves (41, 42) may include solenoid valves that open and close in response to an electrical signal.

[0092] The garment treatment device (1) may include a detergent supply device (50, 60) configured to supply detergent to the tub (20). The detergent supply device (50, 60) may include an upper detergent supply device (50) and a lower detergent supply device (60). The term "detergent" may be used as a comprehensive term for pre-wash detergent, main wash detergent, fabric softener, bleach, etc.

[0093] The upper detergent supply device (50) may be located at the upper part of the tub (20). The upper detergent supply device (50) may be located above the tub (20) in the vertical direction. The upper detergent supply device (50) is a manual detergent that requires the user to add detergent for each wash.

[0094] A supply device or an automatic detergent supply device that stores a large amount of detergent and automatically supplies a predetermined amount of detergent during washing may be included. The upper detergent supply device (50) may be connected to the tub (20) via a detergent connection pipe (51). For example, the upper detergent supply device (50) may be configured to supply solid detergent and / or fabric softener to the tub (20). However, the types of detergents are not limited to the examples described above.

[0095] The detergent connecting pipe (51) may be provided in a U shape. The detergent connecting pipe (51) may be provided as a flexible hose, plastic pipe, or metal pipe. One end of the detergent connecting pipe (51) may be connected to the upper detergent supply device (50), and the other end of the detergent connecting pipe (51) may be connected to the tub (20). In the vertical direction with respect to the ground, one end and the other end of the detergent connecting pipe (51) may be located higher than the bent portion of the detergent connecting pipe (51). Therefore, water may accumulate at the bent portion of the detergent connecting pipe (51). The water accumulated at the bent portion of the detergent connecting pipe (51) may prevent moisture inside the tub (20) from being discharged to the outside through the upper detergent supply device (50).

[0096] The lower detergent supply device (60) may be located at the bottom of the tub (20). The lower detergent supply device (60) may be located vertically lower than the tub (20). The lower detergent supply device (60) may include a manual detergent supply device that requires the user to add detergent for each wash, or an automatic detergent supply device that stores a large amount of detergent and automatically adds a predetermined amount of detergent during the wash. For example, the lower detergent supply device (60) may be provided to supply liquid detergent and / or fabric softener to the tub (20). The type of detergent is not limited to the above-described examples.

[0097] The clothing treatment device (1) may include a drainage device (70) configured to discharge water contained in the tub (20) to the outside. The drainage device (70) may include a drainage pump (71) for discharging water in the tub (20) to the outside of the housing (10).

[0098] The clothing treatment device (1) may include a circulation pump (76) to circulate water in the tub (20) back to the tub (20) through the lower detergent supply device (60).

[0099] The drainage device (70) can be connected to the tub (20) through a tub connection pipe (72). The drainage device (70) can discharge water from the tub (20) to the outside of the housing (10) through a drain pipe (73).

[0100] The garment treatment device (1) may include a water level sensor (200) that detects the water level within the tub (20). The water level sensor (200) may be located outside the tub (20). For example, the water level sensor (200) may be installed at the bottom of the upper detergent supply device (50). The location of the water level sensor (200) is not limited to that exemplified.

[0101] The water level sensor (200) can be connected to a connecting hose (201) extending from a branch pipe (72a) of a tub connecting pipe (72). The water level sensor (200) can be installed at the end of the connecting hose (201) connected to the tub connecting pipe (72). The water level of the connecting hose (201) can be the same as the water level of the tub (20).

[0102] When the water level in the tub (20) rises, the water level in the connecting hose (201) rises. When the water level in the connecting hose (201) rises, the pressure inside the connecting hose (201) may increase. The water level sensor (200) can detect a change in pressure inside the connecting hose (201) and can detect a water level inside the tub (20) corresponding to the pressure inside the connecting hose (201). The water level sensor (200) can generate an electrical signal corresponding to the pressure inside the connecting hose (201). The frequency of the electrical signal generated by the water level sensor (200) may vary depending on the change in pressure inside the connecting hose (201).

[0103] As another example, the water level sensor (200) may be installed inside the tub (20). As the water level inside the tub (20) rises, the pressure applied to the water level sensor (200) increases. The water level sensor (200) can detect the water level inside the tub (20) corresponding to the pressure.
