Hereinafter, a garment treatment device according to various embodiments will be specifically described with reference to the attached drawings.

As an example of a clothing treatment device (1), a washing machine is described, but the idea of the present disclosure is not limited to being applied to a washing machine, and can be applied to all clothing treatment devices (1), such as a dryer that operates by putting laundry in it.

FIG. 1 is a cross-sectional view of a washing machine (1) according to one embodiment of the present disclosure, and FIG. 2 is a perspective view of a washing machine (1) according to one embodiment of the present disclosure.

As shown in FIGS. 1 and 2, the washing machine (1) may be configured to include a housing (10), a tub (20) installed inside the housing (10) to store water, a drum (30) rotatably arranged inside the tub (20), and a motor that drives the drum (30).

The housing (10) may include a housing opening (12) formed to allow access to the interior of the drum (30). The washing machine (1) may include a door (200) for opening and closing the housing opening (12) provided in the housing (10). The door (200) may be rotatably mounted to the housing (10) by a hinge. The door glass (210) of the door (200) may be provided to be transparent or translucent so that the interior of the housing (10) may be visible.

The washing machine (1) may include a tub (20) provided inside the housing (10) to store water. The tub (20) may be placed inside the housing (10). The tub (20) may include a tub opening (22) provided to correspond to the housing opening (12). The tub (20) may be supported inside the housing (10). The tub (20) may have a roughly cylindrical shape with one side open.

The tub (20) can be elastically supported from the housing (10) by a damper. The damper can connect the housing (10) and the tub (20). The damper can be provided to absorb vibration energy and attenuate vibration when vibration generated when the drum (30) rotates is transmitted to the tub (20) and the housing (10).

The washing machine (1) may include a drum (30) provided to accommodate laundry. The drum (30) may be provided rotatably inside a tub (20). The drum (30) may perform washing, rinsing, and/or dehydration while rotating inside the tub (20). The drum (30) may have a generally cylindrical shape with one side open.

A plurality of perforations (33) for the circulation of washing water may be formed around the drum (30), and lifters (34) may be installed on the inner surface of the drum (30) so that laundry can rise and fall when the drum (30) rotates.

The drum (30) may include a drum opening (32) provided to correspond to the housing opening (12) and the tub opening (22). Laundry may be fed into the drum (30) or taken out from the drum (30) through the housing opening (12), the tub opening (22), and the drum opening (32).

The washing machine (1) may include a washing machine drive device (40) configured to rotate a drum (30). The washing machine drive device (40) may include a motor. The motor may include a stator fixed to the tub (20) and a rotor rotatably arranged around the stator. The rotor may rotate by electromagnetic interaction with the stator and transmit rotational force to the drive shaft.

A housing opening (12) is formed on the front panel (11) of the housing (10). The housing opening (12) can be opened and closed by a door (200) installed on the front panel (11) of the housing (10). The door (200) can be equipped with a door glass (210) provided to allow the inside of the drum (30) to be viewed and a door frame (220) supporting the door glass (210).

A diaphragm (100) may be installed between the tub (20) and the door (200). The diaphragm (100) may connect the housing opening (12) and the tub opening (22), form a passage from the housing opening (12) to the tub opening (22), and reduce vibration transmitted to the housing when the drum (30) rotates. In addition, the diaphragm (100) may be arranged between the door (200) and the front panel (11) to prevent water from leaking to the outside of the housing (10).

The diaphragm (100) may be formed of an injection molded thermoplastic elastomer. Since the thermoplastic elastomer has elasticity like rubber at room temperature, the diaphragm (100) formed of the thermoplastic elastomer can effectively dampen vibration transmitted from the tub (20) to the front panel (11) of the housing (10).

The diaphragm (100) is connected to the housing (10) by a fixing member (510). Specifically, the fixing member (510) secures the housing lip portion (14) forming the perimeter of the housing opening (12) and the housing connecting portion (110) of the diaphragm (100).

A diaphragm lip (130) is formed at the front end of the diaphragm (100). It protrudes from the fixed member (510) toward the center of the housing opening (12) and can be formed in an annular shape along the perimeter of the housing opening (12).

When the door (200) of the washing machine (1) is closed, the diaphragm lip (130) can prevent water from leaking between the door (200) and the front panel (11) of the housing (10) by contacting and sealing the door glass (210). In some cases, the diaphragm lip (13) can also prevent water from leaking by contacting and sealing the door frame (220).

Figure 3 is a plan view of the door (200) of Figure 2, Figure 4 is a side view of the door (200) of Figure 2, Figure 5 is a perspective view showing the door (200) of Figure 2 cut away, and Figure 6 is an enlarged cross-sectional view of a washing machine (1) according to one embodiment of the present disclosure.

The door (200) may include a door glass (210) provided to allow viewing of the inside of the drum (30) and a door frame (220) supporting the door glass (210). A portion of the door glass (210) may contact the diaphragm (100) to prevent water inside the drum (30) from leaking out of the housing (10).

Assuming that there is no door glass (210) of the door (200), the door frame (220) may include a frame opening (223) at its center that is arranged to correspond to the housing opening (12) when the door is closed.

The door (200) may be provided to open or close the inside of the washing machine (1). The door (200) may be locked by a door lock device (250). The door lock device (250) may be locked in a manner in which a catch formed on one of the door (200) and the housing (10) and a hook formed on the other of the door (200) and the housing (10) are combined to catch on the catch. The door lock device (250) may be formed in the form of a locking device using a hook, a ring, a bar, or a solenoid, but is not limited thereto.

The washing machine (1) can only operate when the door (200) is closed. When laundry is fed into the washing machine (1), there are cases where the laundry is not fed completely into the drum (30) and thus gets stuck in the door (200). (See Figs. 7 and 8)

Even if laundry is stuck, if the user applies force to close the door (200), the washing machine (1) may operate with the laundry stuck in the door (200). Accordingly, the laundry stuck in the door (200) may rotate by the drum (30) and permanently damage the diaphragm (100), which may cause a leak or damage to the laundry.

By reducing the gap between the door (200) and the housing (10) or between the door (200) and the diaphragm (100), the door (200) can be prevented from closing with laundry stuck in the door (200).

To prevent the door (200) from closing with laundry stuck in it, the door (200) may include a door protrusion (230) that protrudes from the door frame (220) toward the front side (10a) of the housing.

However, it is not necessarily required to protrude from the door frame (220), and it is sufficient if the gap between the door (200) and the housing (10) or between the door (200) and the diaphragm (100) can be reduced so that the door (200) does not close. In other words, the door protrusion (230) may be formed to protrude from the housing (10) rather than the door frame (220).

Referring to FIG. 6, the door frame (220) may include a first edge portion (221) on the inner side of the door frame (220) and a second edge portion (222) extending from the first edge portion (221) to the outer side of the door frame (220).

Specifically, the first border portion (221) may correspond to the front surface of the housing joint portion (110) of the diaphragm (100), and the second border portion (222) may correspond to the front surface (10a) of the housing.

The door protrusion (230) may include a first protrusion (231) protruding from the first frame (221) and a second protrusion (232) protruding from the second frame (222).

The first protrusion (231) may protrude toward the diaphragm (100), specifically, toward the front of the housing joint (110) of the diaphragm (100), and the second protrusion (232) may protrude toward the front (10a) of the housing.

In order to effectively achieve the effect of preventing the door (200) from closing when laundry gets caught in the door (200), it is preferable that the first protrusion (231) contacts the diaphragm (100) and the second protrusion (232) contacts the front surface (10a) of the housing.

Even if the second protrusion (232) and the front surface (10a) of the housing do not come into contact, the second protrusion (232) may include a protrusion surface (2321) that extends vertically so as to be parallel to the front surface (10a) of the housing.

The first protrusion (231) and the second protrusion (232) may each protrude a predetermined distance from the diaphragm (100) and the front surface (10a) of the housing.

The first protrusion (231) corresponds to the diaphragm (100) and the second protrusion (232) corresponds to the front side (10a) of the housing. In order to prevent laundry from getting caught, the second protrusion (232) may be positioned closer to the front side (10a) of the housing than the first protrusion (231).

The closer the gap between the second protrusion (232) and the front surface (10a) of the housing is to the first protrusion (231), the more effectively the door (200) can be prevented from closing.

The wider the area where the laundry is caught in the door (200), the more reliably the door (200) can be prevented from closing. Accordingly, the first protrusion (231) and the second protrusion (232) of the door protrusion (230) may include surfaces parallel to the corresponding diaphragm (100) and the front surface (10a) of the housing, respectively.

For example, the second protrusion (232) may include a protrusion surface (2321) extending in an up-down direction parallel to the front surface (10a) of the housing. In some cases, a portion of the protrusion surface (2321) may come into contact with the front surface (10a) of the housing.

The thickness and length of the part of the laundry that is inserted into the door (200) may be different. Accordingly, the closer the narrowest part of the gap between the second protrusion (232) and the housing (10) is to the first protrusion (231), the more advantageous it may be to prevent the door (200) from being locked.

To this end, the gap between the second protrusion (232) and the housing (10) may be reduced from the lower end of the second protrusion (232) to the protrusion surface (2321). However, it does not necessarily have to be gradually reduced, and it is sufficient if there is a tendency to be reduced.

Referring to FIG. 5, the door (200) may include a border protrusion (224) formed to protrude further upward from the frame opening (223) along the first border portion (221).

The edge protrusion (224) reduces the gap between the door (200) and the housing (10) or the door (200) and the diaphragm (100), so that laundry can be prevented from being caught between the door (200) and the diaphragm (100) or between the door (200) and the housing (10) at the upper part of the door (200) when the washing machine (1) is in operation.

FIG. 7 is a drawing showing a situation in which laundry is hung on a washing machine (1) according to one embodiment of the present disclosure, FIG. 8 is an enlarged cross-sectional view of a situation in which laundry is hung when trying to close a door (200) of a washing machine (1) according to one embodiment of the present disclosure, and FIG. 9 is a plan view of a door (200) of a washing machine (1) according to one embodiment of the present disclosure. The door protrusion (230) of FIG. 9 may include a plurality of protrusions (2301) arranged at predetermined intervals along the perimeter of a frame opening (223).

The predetermined gap between the plurality of protrusions (2301) may be formed narrowly so as to prevent the door (200) from closing when laundry hangs over the diaphragm (100). Specifically, the predetermined gap between the plurality of protrusions (2301) may be formed smaller than the length of each of the plurality of protrusions (2301) in the circumferential direction of the frame opening (223).

Since laundry is most likely to get stuck in the middle of the door (20), the central protrusion among the multiple protrusions (2301) may be formed as the largest.

The door protrusion (230) may include a portion at the side end of the door protrusion (230) in which the cross-sectional area decreases from the center of the door protrusion (230) along the circumferential direction of the housing opening (12).

In other words, it may include a part that connects the rear of the door protrusion (230) and the door frame (220) without creating a chin.

If a corner is formed in the door protrusion (230), when a user applies force to the door (200) while laundry is stuck, the laundry may be damaged by being hit by the corner. However, if a fillet portion with a reduced cross-sectional area is formed in the corner, this problem can be solved.

FIG. 10 and FIG. 11 are enlarged cross-sectional views of a washing machine (1) according to one embodiment of the present disclosure.

Referring to Fig. 10, the rear surfaces of the first frame portion (221) and the second frame portion (222) may be positioned on one plane. In this case, the door frame (220) may be formed to be easily manufactured, which may be advantageous in the manufacturing process.

When laundry is stuck in the door (200), the thickness of the stuck laundry may vary. If the laundry is thin, the door (200) may close when the user applies force to the door (200) even if the first protrusion (231) and the second protrusion (232) are present.

In this case, the washing machine (1) may operate, causing damage to the diaphragm (100), which may result in a water leak or damage to the laundry.

Referring to Fig. 11, in order to solve this problem, the door protrusion (230) may include a third protrusion (233) that further protrudes from the second protrusion (232) toward the front side (10a) of the housing.
