Figure 6 is a diagram for explaining the movement of laundry (C) in the laundry treatment apparatus 1 according to an embodiment. Figure 7 is an enlarged view showing the surroundings of the sealing member 340 of the clothes cleaning device 1 according to the embodiment. Figure 8 is a cross-sectional perspective view of a portion of the sealing member 340 of the laundry treatment device 1 according to an embodiment.

Referring to FIGS. 3 to 6, in the laundry treatment apparatus 1 according to the embodiment, laundry C moves in various directions such as up and down, forward and backward, and left and right in the second washing space 215 during the washing process. You can.

If the tub body 310 has a low-height structure, laundry C may move to the top of the tub body 310 during the washing process. At this time, the laundry C may rise to a position higher than the opening 311 of the tub body 310, and in the process, the laundry C may contact the tub cover 320, the door 330, etc.

Referring to FIGS. 6 and 7 , the laundry treatment device 1 according to the embodiment may have a structure to block laundry C that has risen to a high position from contacting the sealing member 340 . For example, the door 330 may include an anti-friction rib 350 configured to cover the inner portion of the sealing member 340 . Here, the inner part of the sealing member 340 may mean a part that faces the inlet 321 in the horizontal direction when the door 330 is in the closed position.

The anti-friction rib 350 may be provided on the door frame 331. The anti-friction rib 350 may extend from the coupling support portion 3311. For example, it may extend from the inner wall among the side walls forming the coupling support portion 3311. However, the anti-friction rib 350 is not limited to this, and may be formed separately from the coupling support portion 3311 in the door frame 331. For example, the anti-friction rib 350 may be disposed inside the coupling support portion 3311.

The anti-friction rib 350 may protrude toward the inlet 321. When the door 330 is in the closed position, at least a portion of the friction prevention rib 350 may be located inside the inlet 321. For example, the inlet 321 of the tub cover 320 may have a depth equivalent to the thickness of the tub cover 320, and one end of the anti-friction rib 350 may be located inside the inlet 321. there is. The friction prevention rib 350 may be arranged to overlap the tub cover 320 in the horizontal direction.

The friction prevention rib 350 may have a frictional force smaller than that of the sealing member 340. In other words, the frictional force of the sealing member 340 may be greater than the frictional force of the friction prevention rib 350. The anti-friction rib 350 may be an injection molded product. The anti-friction rib 350 may include resin. Through this anti-friction rib 350, it is possible to prevent the laundry C from contacting the sealing member 340, which has a relatively high frictional force.

If the door 330 has a structure that does not include the anti-friction rib 350, the laundry C may repeatedly contact and rub against the sealing member 340, which has high frictional force, during the washing or rinsing process. In this case, the laundry C is damaged due to repeated friction with the sealing member 340, or the surface of the sealing member 340 exposed to continuous friction with the laundry C is worn, etc. Durability may decrease.

On the other hand, in the laundry treatment device 1 according to the embodiment, the friction prevention rib 350 of the door 330 prevents contact between the sealing member 340, which has a relatively large frictional force, and the laundry C, thereby preventing the laundry ( Damage to C) can be prevented, and durability of the sealing member 340 can be prevented from being deteriorated.

Referring to FIGS. 7 and 8 , the sealing member 340 may be configured to be coupled to the door 330 . The sealing member 340 may include a coupling portion 341 coupled to the door 330 and a sealing portion 342 that seals between the tub cover 320 and the door 330. The sealing portion 342 extends from the coupling portion 341 and may be one body with the coupling portion 341.

The door 330 may include a coupling support portion 3311 that supports the coupling portion 341. The coupling support portion 3311 may include a sealing groove 3312 provided to allow the coupling portion 341 to be assembled. A fixing protrusion 3313 protruding in a direction perpendicular to the insertion direction of the coupling portion 341 of the sealing member 340 may be provided inside the sealing groove 3312.

The coupling portion 341 may have a hook structure that is elastically deformed by the fixing protrusion 3313. A hook structure may be formed on one side of the coupling portion 341. However, the formation of the hook structure is not limited to this, and may be modified in various ways depending on the arrangement of the fixing protrusion 3313.

In the process of inserting the coupling portion 341 into the sealing groove 3312, a portion of the coupling portion 341 is elastically deformed by the fixing protrusion 3313 of the sealing groove 3312 and then recovers to its original shape, thereby forming a predetermined shape. Can be fixed in position.

The sealing portion 342 may have an empty cavity 3420 that is elastically deformed when the door 330 is in the closed position. The cross-sectional shape of the sealing portion 342 may have a closed loop shape surrounding the cavity 3420.

The sealing portion 342 may have at least one partition wall 343 that divides the cavity 3420 into a plurality of pieces. For example, the cavity 3420 may be divided into a first cavity 3421 and a second cavity 3422 by a partition wall 343. However, the number and shape of cavities 3420 are not limited to this and may vary depending on the shape and number of partitions 343.

Using this partition wall 343, the strength of the sealing portion 342 of the sealing member 340 can be reinforced. By reinforcing the strength of the sealing portion 342, durability and sealability of the sealing member 340 can be improved.

The sealing portion 342 may include a sealing protrusion 345 protruding toward the friction prevention rib 350 . The sealing protrusion 345 may contact and pressurize the outer surface of the anti-friction rib 350. Thus, washing water can be prevented from penetrating between the friction prevention rib 350 and the sealing member 340.

FIGS. 9 and 10 are diagrams for explaining the manufacturing process of the sealing member 340 according to an embodiment. FIG. 9 shows a state before adhesion of the sealing member 340, and FIG. 10 shows a state before adhesion of the sealing member 340. Indicates the after status.

Referring to FIG. 9, the cross-sectional shape of the sealing member 340 has a closed loop shape surrounding the cavity 3420, so the sealing member 340 can be manufactured by extrusion molding. The sealing member 340 may be extruded so that the cavity 3420 extends along the longitudinal direction. As an example, a mother sealing member corresponding to a plurality of sealing members 340 may be formed through one-time extrusion molding. The mother sealing member 340 may be cut into multiple pieces and used as multiple or single sealing members 340.

Referring to FIG. 10, the extruded sealing member 340 may be bent so that both ends 3401 and 3402 face each other, and then the both ends 3401 and 3402 may be bonded. As an example for adhesion of both ends 3401 and 3402, at least one of the both ends 3401 and 3402 of the sealing member 340 may be heated and melted to adhere both ends 3401 and 3402. However, since this adhesive method is illustrative, it is not limited thereto.

Before adhesion of both ends 3401 and 3402 of the sealing member 340 or after adhesion of both ends 3401 and 3402 of the sealing member 340, a cavity 3420 is formed in the sealing portion 342 of the sealing member 340. ) may be formed with a plurality of through holes (TH) for communicating with the outside.

Through this through hole (TH), liquid or air unintentionally introduced into the cavity 3420 can be removed.

The sealing member 340 manufactured in this way can be assembled to the door 330. As shown in Figure 7, the sealing member 340 can be fixed to the door 330 by inserting the coupling portion 341 of the sealing member 340 into the coupling support portion 3311 of the door 330.

Referring again to FIGS. 4 and 7 , the tub cover 320 may be provided with a seating groove 324 for seating the door 330 when the door 330 is closed. The seating groove 324 may be provided around the inlet 321 in the tub cover 320. The seating groove 324 may be concave downward compared to the adjacent portion of the tub cover 320. A protrusion 325 protruding upward may be provided in the portion of the seating groove 324 facing the inlet 321.

The protrusion 325 may perform the function of pressing the sealing member 340 when the door 330 is in the closed position. Additionally, the protrusion 325 may perform a dam function to block wash water inside the tub body 310 from flowing into the seating groove 324.

In the process of moving the door 330 to the closed position, the sealing member 340 contacts the upper surface of the protrusion 325 and is pressed by the upper surface of the protrusion 325, so that it may be elastically deformed. The sealing member 340 is elastically deformed by the protrusion 325 to prevent water from penetrating between the sealing member 340 and the door cover 332.

Meanwhile, the sealing member 340 may be arranged so that the through hole TH overlaps the tub cover 320. The plurality of through holes TH may be disposed outside the protrusion 325 of the tub cover 320. As the through hole (TH) is disposed outside the protrusion 325 of the tub cover 320, the protrusion 321 will block liquid exiting the through hole (TH) from flowing into the inlet 321. You can.

FIG. 11 is a cross-sectional view illustrating the operation of the sealing member 340 when the door 330 opens and closes the inlet 321 in the clothing processing device 1 according to the embodiment. FIG. 12 is an enlarged view of a part of FIG. 11, and FIG. 13 is an enlarged view of another part of FIG. 11.

Referring to FIG. 11, as the door 330 rotates around a predetermined hinge axis 322, the sealing member 340A is disposed at a position relatively close to the hinge axis 322 during the process of closing the door 330. ) and the timing at which the sealing member 340B disposed at a position relatively distant from the hinge axis 322 contacts the door cover 332 and the force applied by the door cover 332 may be different.

For example, as shown in FIG. 12, the sealing member 340A disposed close to the hinge axis 322 contacts the door cover 332 at a relatively early time and is applied with greater force by the door cover 332. While being pressed, as shown in FIG. 13, the sealing member 340B disposed at a position far from the hinge axis 322 contacts the door cover 332 at a relatively late point in time and is pressed with a small force by the door cover 332. It can be. Taking this into consideration, the surrounding structures of the door cover 332 in contact with the sealing member 340A close to the hinge axis 322 and the sealing member 340B far from the hinge axis 322 may be different. You can. For example, the distance D1 between the door cover 332 and the friction prevention rib 350 adjacent to the hinge axis 322 is the distance between the door cover 332 and the friction prevention rib 350 adjacent to the hook receiving portion 323. It may be different from the distance between them (D2). The distance D1 between the door cover 332 adjacent to the hinge axis 322 and the anti-friction rib 350 is the distance between the door cover 332 adjacent to the hook receiving portion 323 and the anti-friction rib 350 ( It can be shorter than D2). In the door cover 332 adjacent to the hinge axis 322, the protrusion 325A may not be disposed at the inner end. For example, the protrusion 325A may be disposed slightly outward from the inner end. On the other hand, the protrusion 325B may be disposed at the inner end of the door cover 332 adjacent to the hook receiving portion 323.

The sealing member 340 according to the embodiment has a closed-loop cross-sectional shape of the sealing portion 342, and thus can provide a large sealing area and have a wide elastic deformation range. Accordingly, even if the structure of the door cover 332 that presses the sealing member 340 is different, the sealing member 340 can provide a predetermined sealing force.

Meanwhile, in the above-described embodiment, the clothing processing device 1 includes a first clothing processing device 100 and a second clothing processing device 200 that provide a first washing space 115 and a second washing space 215. The explanation is centered on the example, but is not limited to this. For example, as shown in FIG. 14 , the clothing processing device 1A according to the embodiment may include a second clothing processing device 200 that provides a second washing space 215 . For example, the laundry treatment apparatus 1A may have a single tub 300 having an upward opening 311 without a first tub having a front opening 311 . In this case, the tub cover 320, sealing member 340, and door 330 described above may be applied to a single tub 300.
