Description

Garment processing equipment

[0001] The present invention relates to a clothing treatment device.

[0002] Generally, a clothing treatment device such as a washing machine that performs a washing cycle to remove foreign substances from clothing includes a cabinet forming an exterior, a tub accommodated inside the cabinet to store water, and a drum accommodated in the tub to store clothing.

[0003] Conventional clothing treatment devices are equipped with a water supply unit that is connected to an external water source and supplies water to a tub, so that water can be supplied and clothes can be washed together with detergent.

[0004] Figure 1 schematically shows the structure for supplying water to the inside of a tub of a conventional clothing treatment device.

[0005] A door (I) is provided in front of the drum (D) accommodated inside the tub (T) to be opened and closed, and a gasket (G) may be provided between the tub (T) and the door (I) to prevent water or clothes accommodated in the tub (T) from leaking out of the tub (T).

[0006] The above tub (T) or gasket (G) may be connected to an external water source and may be equipped with a nozzle (N) that supplies water and sprays water into the interior of the drum (D). The nozzle (N) is provided to spray water toward the lower portion of the drum (D), thereby wetting clothes contained in the drum (D).

[0007] In this way, the conventional clothing treatment device can evenly wet the clothing first during the water supply process.

[0008] Figure 2 illustrates a state in which detergent is applied to the gasket of a conventional clothing treatment device.

[0009] Figure 2(a) shows detergent on the gasket, and Figure 2(b) shows detergent on the door.

[0010] When water is supplied to the above tub (T), detergent can also be supplied through the detergent box connected to the water supply pipe, and as the drum (D) rotates, physical force is transmitted to the clothes, and as the water and detergent rub against each other, foreign substances can be separated from the clothes.

[0011] During this process, foam caused by detergent may be generated in the water contained in the tub (T), and the generated foam (T) has a lower specific gravity than water and can be placed at the highest water level.

[0012] As a result, a state in which a large number of bubbles (E) are present may be maintained except for the area where the nozzle (N) is installed among the above gaskets (G).

[0013] In addition, since the water sprayed from the nozzle (N) is directed only toward the inside of the drum (D), foam (E) may be applied to the door (I) positioned in front of the nozzle (N).

[0014] The foam adhering to the gasket (G) and door (I) above may not only be organic matter generated by detergent, but may also combine with foreign substances separated from clothing, and may remain even after all water has been drained from the tub (T). Furthermore, the remaining foam may serve as a breeding ground for bacteria such as mold, potentially causing the interior of the clothing treatment device to rot.

[0015] Meanwhile, in the case of the above gasket (G), the area far from the nozzle (N) can be cleaned of bubbles or foreign substances by water remaining in the tub (T) or water sprayed from the nozzle (N).

[0016] The above nozzle (N) is generally installed on the upper part of the gasket (G) so that it can spray water up to the rear surface of the drum and continuously spray water even when water is contained in the tub (T), and the part where the nozzle (N) is installed is set so that it does not become submerged in water even when water is contained at the highest level inside the tub (T).

[0017] Therefore, there was a problem that the area adjacent to the nozzle (N) and the upper area of ​​the gasket (G) among the above gaskets (G) had no opportunity to be cleaned, so bubbles or foreign substances always remained.

[0018] As a result, conventional clothing treatment devices had the problem of clothing being contaminated by remaining foam or foreign substances even after the washing cycle was completed.

[0019] The present invention aims to provide a clothing treatment device capable of washing not only the drum but also the inner surface of a gasket with water.

[0020] The present invention aims to provide a garment treatment device capable of washing a gasket area adjacent to a nozzle.

[0031] The above washing slit can be arranged separately from the main injection hole.

[0032] The above-mentioned spray nozzle includes a blocking rib extending from the rear side of the washing hole to both sides to block water sprayed from the washing hole from being sprayed forward, and the washing slit may be provided by being recessed from the surface of the guide body arranged on both sides of the main spray hole to the blocking rib.

[0033] The above-mentioned washing slit may be provided with a height that decreases from the surface of the guide body toward the washing hole.

[0034] The lower surface of the above-mentioned washing slit may be arranged to be inclined so that the height decreases as it goes from the washing hole to the surface of the guide body.

[0035] The above washing slit may include a first washing slit extending from the first washing hole to the surface of the guide body, and a second washing slit extending from the second washing hole to the surface of the guide body.

[0036] The angles of the first washing slit and the second washing slit may be formed differently from each other.

[0037] The above injection nozzle may include an auxiliary injection hole that is positioned above the main injection hole and sprays water further rearward than the main injection hole.

[0038] The above auxiliary injection hole may be arranged at the upper part of the guide body.

[0039] The above injection nozzle may further include a partition rib arranged inside the auxiliary injection hole to divide the sprayed water.

[0082] The above door (200) may further include a sensing unit (240) that is equipped to receive a user's pressure or touch and separate the door (200) from the cabinet (10).

[0083] The sensing unit (240) may be configured to detect physical contact with a user. For example, the sensing unit (240) may include any configuration that can detect physical contact with a user, such as a touch film, touch panel, physical button, or piezoelectric element installed on the door (200).

[0084] The door (200) can be opened from the cabinet (10) without being pressed toward the cabinet (10) when the user touches or presses the sensing unit (240). This can prevent damage or scratches from occurring when the door (200) is pressed by a user or an object.

[0085] The sensing unit (240) may be provided near the pressurizing unit (250). Thus, the user can intuitively recognize that the sensing unit (240) and the pressurizing unit (250) are areas that receive user input.

[0086] The sensing unit (240) may be built into the door (200), and may be provided so as to be displayed on the outer surface of the door (200). Accordingly, the sensing unit (240) may further include a separate light-emitting body. Of course, the area where the sensing unit (240) is installed on the surface of the door (200) may be indicated by marking, shading, etc.

[0087] The garment treatment device of the present invention may additionally include an auxiliary device (5) arranged at the bottom of the composite device (3). The auxiliary device (5) may be arranged at the bottom of the composite device (3), and the composite device (3) may be arranged and mounted above the auxiliary device (5).

[0088] The auxiliary device (5) may include an auxiliary cabinet (10b) placed at the bottom of the cabinet (10) of the composite device (4), and a drawer (80) extended forward from the auxiliary cabinet (10b).

[0089] An open input unit (84) may be placed in front of the drawer (80) to receive a withdrawal command from the user to withdraw the drawer (80) forward.

[0090] The above open input unit (84) may be configured in any way as long as it can receive a withdrawal command by making contact with the user's body. For example, it may be configured as a touch panel or button.

[0091] The height at which the above-mentioned composite device (4) is placed can be increased due to the above-mentioned auxiliary device (5). Accordingly, when the above-mentioned composite device (4) is equipped with a front-load type in which the door (200) is placed at the front of the cabinet (10), the position of the opening (14) is also increased, so that the user can easily access the door (200) with less or no bending of the waist.

[0092] The detailed configuration of the above composite device and the above auxiliary device is described later.

The water supply pipe (52) may be coupled to the tub body (21) or may have its end coupled to the gasket (23).

[0103] If the above water supply pipe (52) can supply water to the above tub (20), the above water supply pipe (52) may be connected to any part of the tub (20).

[0104] The water supply pipe (52) of the water supply unit (50) may be connected to a gasket (24). A spray unit (500) coupled to the end of the water supply unit (52) may be installed on the gasket (24). The spray unit (500) may be provided to evenly spray water supplied from the water supply pipe (52) into the interior of the drum (30).

[0105] The above drainage unit (60) may include a drain pipe (61) connected to the lower portion of the tub (20) to drain water from the tub (20), a drainage pump (62) that provides power to drain water supplied from the drain pipe (61) to the outside of the cabinet (10), and a drainage pipe (63) that extends from the drainage pump (62) to the outside of the cabinet (10) to drain water.

[0106] The garment treatment device of the present invention may further include a water level sensor (24) for detecting the water level of the tub (20). The water level sensor (24) may be provided in any configuration as long as it can detect the water level inside the tub (20). For example, the water level sensor (24) may include a communication pipe that is connected to the tub (20) and has a blocked end, and a device portion that is positioned on the upper portion of the communication pipe and detects a pressure change inside the communication pipe.

[0107] The clothing treatment device of the present invention may further include a support member (70) that supports the tub (20) inside the cabinet (10).

[0109] In addition, the clothing treatment device of the present invention may further include a heat supply unit (90) capable of circulating air inside the tub (20) or the drum (30) and heating the air.

[0110] The above heat supply unit (90) may be placed lower than the tub (20).

[0111] However, since the tub (20) is the closest configuration to the drum (30) and the lower part of the tub (20) is provided with a drainage part (60), the heat supply part (90) can be installed and placed on the tub (20).

[0112] The heat supply unit (90) may be positioned and secured on the upper portion of the tub (20). That is, the heat supply unit (90) may be positioned above the opening of the tub.

[0113] The heat supply unit (90) may include at least one of a circulation path (91) extending from the tub (20) in at least one of the front-back / left-right directions to circulate air inside the tub (20), an evaporator (92) received in the circulation path (91) to cool the air and condense moisture, a condenser (93) disposed downstream of the evaporator to heat the air, a compressor (94) disposed outside the circulation path (91) to supply refrigerant that heats the air to the condenser (93), an expansion valve that expands and cools the refrigerant discharged from the condenser (93) and delivers it to the evaporator (92), and a circulation fan (96) disposed inside the circulation path (91) to provide power to circulate the air.

[0114] The above circulation path (91) may be provided so that one end is connected to the upper rear of the tub body (21) and the other end is connected to the upper front of the tub body (21) or the gasket (24).

[0115] The above circulation fan (96) can be driven so that air is sucked into the circulation path (91) from the rear of the drum (30) and the air is discharged into the drum body (31) through the inlet (35).

[0116] Accordingly, the hot air generated from the heat supply unit (90) can be introduced into the inlet (35) and evenly supplied to the drum (30), so that the clothes can be evenly dried. In addition, the air used to dry the clothes can be introduced into one end of the circulation path (91) without difficulty by passing through the through hole (33) by the negative pressure provided by the blower fan (96).

[0117] As a result, the heat supply unit (90) may be provided so that the drum (30) is accommodated in the tub (20) and a plurality of through holes (33) are provided on the outer surface of the drum (30), so that even if the air resistance is high, hot air can be supplied into the drum body (31).

[0118] Since the above heat supply unit (90) has the above tub (20) positioned at the bottom, the collection unit and storage tank for collecting condensate can be omitted. That is, the water condensed within the above circulation path (91) can be collected in the above tub (20) and discharged to the above drainage unit (60).

[0119] The above circulation path (91) can be arranged to extend in an L-shape from the upper part of the tub (20) to secure the volume through which air moves or the area of ​​the evaporator and condenser.

[0120] That is, after extending forward from one side of the upper rear of the tub body (21), it can extend to the other side of the upper front of the tub body (21).

[0121] The above circulation path (91) may include an inlet portion (91a) extending from the rear to the front of the tub body (21), a moving portion (91b) extending from the inlet portion to the front other side of the tub body (21) or the gasket (24), and a discharge portion (91c) extending downward from the moving portion and communicating with the inside of the gasket (24).

[0122] The above duct can extend left and right from the top of the tub (20), and a filter (99), an evaporator (92), and a condenser (93) can be sequentially arranged inside.

[0123] The above circulation fan (96) may be provided to communicate with the above circulation path (91).

[0124] The above circulation fan (96) may be installed inside the circulation path (91) and may include a housing connecting the moving part and the discharge part.

[0125] The above circulation fan (96) is placed in front of the tub body (21) to evenly distribute the weight of the rear of the tub body (21) to which the driving unit (40) is coupled.

[0126] The above circulation fan (96) can be driven to move air from the inlet to the outlet.

[0127] The garment treatment device of the present invention can perform multiple courses for treating garments based on the above configuration. The courses may include a washing course for removing foreign substances from garments and a drying course for removing moisture from garments.

[0128] The clothing treatment device of the present invention may include an integrated control unit in which a control unit for performing a washing course and a control unit for performing a drying course are integrated, and the integrated control unit may be built into the control panel (100) or may be installed separately from the control panel (100) and mounted inside the cabinet (10).

[0129] The clothing treatment device of the present invention may further include a detergent box (700) for storing detergent supplied to the tub (20).

[0130] The detergent box (700) may be positioned lower than the tub (200). The detergent box (700) can prevent interference with the heat supply unit (90) positioned above, and can be exposed to the user without difficulty even when the complex device (4) is raised due to the auxiliary device (5).

[0131] The detergent box (700) may be equipped with a detergent body that holds detergent and a detergent pump that sprays the detergent held in the detergent body into the tub (20). Accordingly, water from the tub (20) can be prevented from randomly entering the detergent box (700) or detergent can be prevented from randomly being supplied.

[0132] The above detergent box (700) may be equipped to supply detergent to at least one of the drainage unit (60) or the circulation unit (65).

[0133] When supplying detergent to the above circulation unit (65), the detergent can be supplied to the tub (20) while driving the circulation pump, etc., and during the circulation process, the detergent can be more easily dissolved in water and the detergent can be evenly supplied to the clothes.

[0134] A filtration filter (800) can be placed between the above-mentioned drainage pump (62) and the circulation unit (65), thereby preventing foreign substances discharged from the tub (20) from being re-introduced into the circulation unit (65).

[0135] The above filter (800) can be exposed in front of the detergent box (700) and can be detachably installed in the front.

[0136] The above cabinet may further include a base (15) that supports the above filter (800) and the above detergent box (700).

[0137] The above base (15) can form the lower surface of the cabinet (10).

[0138] The above base (15) can be provided to support the support (70) and can support the detergent box (700) and the filter (800) without interfering with the support (70).

[0139] The detergent box (700) may be detachably mounted on the base (15) and may be configured to be pulled out and inserted forward from the base (15). Thus, the user can continuously replenish detergent in the detergent box (700) and also wash it.

[0140] The front of the above base (15) may further include a step panel (16) positioned at the bottom of the front panel (11) to guide the withdrawal and entry of at least one of the detergent box (700) and the filter (800).

[0141] The above step panel (16) may have a hole through which the detergent box (700) and the filter (800) are inserted and removed, and may block the base (15) from being exposed to the outside.

[0142] The above-mentioned step panel (16) may be provided separately from the front panel (11). Accordingly, the front panel (11) and the step panel (16) may be provided with different materials. As a result, even if the front panel (11) is provided with a metal material that is rigid or difficult to form, the step panel (16) may be provided with a material that is easy to form so as to guide or expose the withdrawal of one or more of the detergent box (700) and the filter (800).

[0143] Figure 5 illustrates a cross-section of the internal structure of the cabinet of the garment treatment device of the present invention.

[0144] The above drum (30) may include a drum body (31) that is rotatably provided on the tub body (21) to store clothes, and an inlet (35) that is positioned at the front of the drum body (31) and communicates with the inlet (22) and the opening (14).

[0145] The above drum body (31) may be provided in a cylindrical shape, and a through hole (33) communicating with the inside of the tub body (21) may be provided on the back surface or outer surface. The above drum body (31) may be provided with a metal material.

[0146] The clothing treatment device of the present invention may include a driving unit (40) having the same structure as a general washing machine (1). The driving unit (40) may be coupled to the tub (20) and provided to rotate the drum (30).

[0147] The above driving unit (40) may include a stator (41) coupled to the rear of the tub body (21), a rotor (42) rotated by the stator (41), and a rotation shaft (43) connecting the rotor (42) and the drum (30).

[0148] The above tub body (21) has a rotation shaft (43) passing through the back surface, and a bearing housing that rotatably supports the rotation shaft (43) can be installed.

[0149] The clothing treatment device of the present invention may further include a circulation unit (65) that recirculates and supplies the water of the tub (20).

[0150] The above circulation unit (65) may include a circulation pump that is in communication with the drainage pump (62) or is placed on one side of the drainage pump (62), and a circulation hose that supplies water drained from the tub body (21) back to the tub (20).

[0151] In this way, water can be saved by reusing the water in the tub (20) during the washing cycle or rinsing process, and the washing efficiency can also be increased by evenly dissolving detergent, etc. through the circulation section (65).

[0152] The door (200) may include a front portion (210) forming the front of the door, a door frame (220) forming the side of the door (200), coupled to the front portion (210) and mounted on the mounting portion (12), and a rear portion (230) coupled to the rear of the door frame (220).

[0153] The front part (210) and the rear part (230) are made of a transparent material, and the door frame (220) is provided in a ring shape so that the inside of the inlet (22) can be exposed to the front of the cabinet (10).

[0154] The rear portion (230) can be coupled to the door (200) and inserted into the gasket (23), and the lower portion protrudes further than the upper portion so that it can be inserted into the inlet (22).

[0155] The rear portion (230) can prevent water or clothing contained in the tub body (21) or drum (30) from approaching the gasket (23). Therefore, even if the drum (30) rotates rapidly, water from clothing can be prevented from accumulating on the gasket (23) or from leaking into the interior of the cabinet (10).

[0156] In addition, the clothing can also be prevented from being concentrated in the inlet (22) portion by colliding with the rear portion (230) and moving back into the drum (30).

[0157] The above-mentioned spray unit (500) is coupled to the gasket (23) and can spray water toward the inside of the inlet (22). As a result, when the above-mentioned spray unit (500) is coupled to the above-mentioned tub body (21), water can be evenly sprayed toward the lower part of the drum body (21) without being obstructed by the outer surface of the drum (30) or the inlet (35).

[0158] Since the main purpose of the above-mentioned spray unit (500) is to supply water to the tub (20) and spray water directly onto clothing, it may be common to spray water toward the rear of the door (200).

[0159] However, the spray unit (500) of the present invention can wash the gasket (23) and the rear portion (230) by spraying at least some of the water onto the inner surface or rear portion (230) of the gasket (23). As a result, even if there is foam or foreign matter remaining on the gasket (23) and the rear portion (230), it can be washed away during the process of spraying water.

[0160] As a result, the washing process can be disclosed as it is by minimizing the amount of foam remaining on the rear part (230) of the door during the washing cycle, and when the washing cycle is finished, the detergent and foreign substances can be prevented from remaining inside the clothing treatment device, thereby maintaining cleanliness.

[0161] Figure 6 shows the gasket structure of the garment treatment device of the present invention in detail.

[0162] In the garment treatment device of the present invention, a water supply pipe (52) extending from a water supply valve (51) or an auxiliary pipe branching from the water supply pipe (52) may be directly connected to a spray nozzle (500). The spray nozzle (500) may be provided such that one end is connected to the end of the water supply pipe (52) and the other end is connected to the gasket (23) so as to spray water into the interior of the gasket (23).

[0163] The above gasket (23) may be provided with a nozzle installation hole (231) to which the injection nozzle is coupled, and an air inlet hole (233) communicating with the circulation path (91). The nozzle installation hole (231) is positioned closer to the upper part of the gasket (23) than the lower part, and the air inlet hole (233) may be positioned eccentrically to one side from the upper part of the gasket (23) in consideration of the arrangement of the circulation duct (91).

[0164] Meanwhile, the garment treatment device of the present invention may further include a steam supply unit capable of supplying steam to the inside of the tub (20). Steam supplied from the steam supply unit may also be coupled to the gasket (23) to supply the steam to the garments contained in the drum (30).

[0165] In this case, the gasket (23) may include a steam supply hole (232) to which a steam pipe for supplying the steam is connected on one side of the nozzle installation hole (231).

[0166] The above nozzle installation hole (231) can be placed higher than the air inlet hole (233).

[0167] The above-mentioned spray unit (500) may be provided so as to be coupled to the nozzle installation hole (231) and to spray water onto the lower surface of the drum (30). Furthermore, the above-mentioned spray unit (500) may be provided so as to be coupled to the nozzle installation hole (231) and to spray water onto at least one of the inner surface of the gasket (23) and the rear portion (230) of the door.

[0168] Figure 7 illustrates a structural example of the injection unit (500) of the present invention.

[0169] The injection unit (500) of the present invention may include an inlet pipe (510) that is connected to the end of the water supply pipe (52) or a branch pipe branching from the water supply pipe (52) and at least a portion of which is inserted into the gasket (23), and an injection nozzle (540) that is disposed at the lower portion of the inlet pipe (510) and exposed to the inner surface of the gasket (23).

[0170] The above inlet pipe (510) may include a guide hollow portion that guides water supplied from a water supply pipe (52) or the like to the spray nozzle (540), and the spray nozzle (540) may be arranged at the end of the inlet pipe (510) to spray the supplied water to the outside of the spray unit (500).

[0171] The above injection unit (500) may further include an installation plate (530) provided between the inlet pipe (510) and the injection nozzle (540) and having a larger area than the inlet pipe (510) and the injection nozzle (540) to prevent the injection unit (500) from being separated from the gasket (23).

[0172] The above inlet pipe (510) may be placed on one side or the upper side of the installation plate (530), and the injection nozzle (540) may be placed on the other side or the lower side of the installation plate (530).

[0173] The above inlet pipe (510), the injection nozzle (540), and the installation plate (530) may be provided as separate parts, or may be manufactured as one piece.

[0174] The installation plate (530) can be installed on the inner surface connecting the opening (14) and the inlet (22) of the gasket (23).

[0175] Since the outer surface of the inner surface of the gasket (23) is the area where the rear part (230) of the door (200) is inserted, the installation plate (530) is exposed to the outer surface of the inner surface of the gasket (23), and the injection nozzle (540) can also be exposed to the outer surface of the inner surface of the gasket (23).

[0176] The above installation plate (530) may be installed on the inner surface of the gasket (23) and may not be exposed to the outside of the gasket (23), and only the injection nozzle (540) may protrude to the outside of the inner surface of the gasket (23) and may be exposed to the outside of the gasket (23).

[0177] The above installation plate (530) can prevent the injection part (500) from coming out of the inner surface of the gasket (23) even when strong water pressure is applied to the inlet pipe (510).

[0178] From another perspective, the inlet pipe (510) is provided in the shape of a pipe that is connected to the end of the water supply pipe (52) to receive water, and the installation plate (530) may extend outward from an outer surface disposed between one end and the other end of the inlet pipe (510) and be seated on the gasket (23). The installation plate (530) may be provided in a flat or plate shape.

[0179] The above injection nozzle (540) can extend from the installation plate (530) in the opposite direction to the inlet pipe (510) to spray water.

[0180] When the above installation plate (530) is installed on the upper part of the gasket (23), the injection nozzle (540) can extend to the lower part of the installation plate (530).

[0181] The above-mentioned spray nozzle (540) may be provided with a plurality of through holes to spray water in various directions. This allows water to be sprayed to multiple areas to be supplied through a single inlet pipe (510), simplifying the configuration of the spray unit (500).

[0182] The above injection nozzle (540) may include a guide body (541) having a hollow portion that protrudes from the inner surface of the gasket (23) into the opening (22) and communicates with the inlet pipe (510).

[0183] The above guide body (541) may be provided in any shape and size as long as the plurality of through holes communicating with the hollow body do not interfere with or are connected to each other.

[0184] The above guide body (541) may be provided in a spherical shape as shown, but may also be provided in a rod shape or a circular shape.

[0185] The cross-sectional area or diameter of the above guide body (541) may be provided to be equal to or larger than that of the above inlet pipe (510).

[0186] The above injection nozzle (540) may include a main injection hole (542) that penetrates the guide body (541) and discharges the water toward the back of the drum, and a cleaning hole (544) that penetrates the guide body (541) but is spaced apart from the main injection hole (542) and sprays the water toward the gasket (23).

[0187] The main injection hole (542) may be provided so as to penetrate the guide body (541) at an angle. As a result, water discharged from the guide body (541) can be directly sprayed toward the lower portion of the drum (30). Clothing placed at the lower portion of the drum (30) can be directly wetted by the main injection hole (542).

[0188] The above main injection hole (542) may be provided to spray water in the forward and backward direction from the gasket (23) or toward the driving unit (40). This allows water to be supplied to the rear of the drum (30) as much as possible.

[0189] The injection nozzle (540) of the present invention may further include a washing hole (544) provided on at least one of both sides of the main injection hole (542) to spray water toward the gasket (23).

[0190] The above washing hole (544) may be provided to communicate with the inlet pipe (510) and receive water from the inlet pipe (510) and spray water. Inside the guide body (541), the washing hole (544) and the inlet pipe (510) communicate, and the main spray hole (542) and the inlet pipe (510) communicate, but the washing hole (544) and the main spray hole (542) may not communicate with each other and may be completely separated.

[0191] Accordingly, all of the washing water flowing into the washing hole (544) can be sprayed toward the gasket (23). The washing hole (544) can extend from the guide body (541) toward the inner surface of the gasket (23). The washing hole (544) can be arranged to spray water toward the inner surface of the gasket (23) at the installed portion.

[0192] In this way, the injection unit (540) can spray water on at least one of the inner surfaces of the gasket (23) facing both sides of the injection unit, and directly wash the inner surface of the gasket (23).

[0193] Since the above-mentioned cleaning hole (544) can clean both sides where the injection unit (540) is installed, the entire inner surface of the gasket (23) can be cleaned from the top of the gasket (23).

[0194] Meanwhile, the injection nozzle (540) may include an auxiliary injection hole (543) that is positioned above the main injection hole (543) and sprays water further rearward than the main injection hole (542).

[0195] The above auxiliary injection hole (543) may be provided to penetrate the upper part of the guide body (541) and communicate with the inlet pipe (510).

[0196] The above auxiliary injection hole (543) can be placed on the upper part of the guide body (541), and in order to secure the flow rate, the installation plate (530) can be extended in a stepwise manner to an adjacent area away from the guide body (541) in the part where the auxiliary injection hole (543) is formed.

[0197] Meanwhile, the injection unit (500) may further include a steam pipe (520) that is spaced apart from the inlet pipe (510) in the installation plate (530) and supplies steam. The steam pipe (520) may include a steam cavity (521) through which steam passes and is discharged.

[0198] The above injection unit (500) can simplify the configuration of being connected to the gasket (23) by having the injection nozzle (540) and the steam pipe (520) as one unit.

[0199] The above injection unit (500) may further include a blocking rib (550) extending to both sides of the guide body (541).

[0200] The above blocking rib (550) can prevent water sprayed from the spray nozzle (540) from being sprayed unnecessarily forward, and can concentrate the water sprayed from the spray nozzle (540) so that it is sprayed at least to both sides and the rear of the spray nozzle (540).

[0201] As a result, the cleaning power can be maximized by securing the flow rate of water sprayed on the rear of the door (230) and the gasket (23) where foreign substances or foam may be present.

[0202] Figure 8 specifically illustrates the structure of the injection unit (500) of the present invention.

[0203] Figure 8(a) illustrates a structure in which a guide hollow (511) and a cleaning hole (544) inside an inlet pipe (510) are connected to each other, Figure 8(b) illustrates a structure in which the injection unit (500) is viewed from the rear, and Figure 8(c) illustrates a structure in which a guide hollow (511) inside an inlet pipe (510) and an auxiliary injection hole (543) are connected to each other.

[0204] The above main injection hole (542) may be provided so that its area increases as it goes from the inlet pipe (510) to the surface of the guide body (541). Accordingly, the pressure of the water discharged from the main injection hole (542) gradually decreases, so that when it is sprayed from the main injection hole (542), it can spread out over a larger area than the area of ​​the main injection hole (542).

[0205] Accordingly, water can be evenly sprayed not only on clothes or the lower surface of the drum placed in the direction of movement of the main spray hole (542), but also on both sides.

[0206] The above injection nozzle (540) may further include a dispersion rib (5431) extending from the guide body (541) to the lower portion of the main injection hole (542).

[0207] The above-mentioned dispersion rib (5431) may extend from the guide body (541) at a different slope from the slope at which the main injection hole (542) extends from the guide body (541).

[0208] The above dispersion rib (5431) may be extended at a slope more gentle than the slope of the main injection hole (542), for example, may be extended at 90 degrees.

[0209] Accordingly, the dispersion rib (5431) can be provided to collide with at least a portion of the water discharged from the main injection hole (542) in the guide body (541).

[0210] The above-mentioned dispersion rib (5431) can perform the function of dispersing water sprayed from the main injection hole (542) to the left and right. Accordingly, among the clothes accommodated in the drum body (31), water sprayed from the main injection hole (542) can be supplied not only to the clothes placed in the straight rear region of the main injection hole (542), but also to the clothes placed on both sides of the main injection hole (542).

[0211] The above-mentioned dispersion rib (5431) may be provided in an upwardly convex shape, and may be provided so that the high point faces the main injection hole (542).

[0212] The area of ​​the above dispersion rib (5431) can be formed to be equal to or larger than the end area of ​​the main injection hole (542).

[0213] The above guide body (541) may further include a washing slit (545) that is sunken from at least one of both sides of the main injection hole (542) to the washing hole (544) to guide water sprayed from the washing hole (544).

[0214] The above-mentioned cleaning hole (544) is provided to penetrate the guide body (541) toward the inner circumference of the gasket (23). However, the cleaning slit (545) is provided to penetrate from the rear of the guide body (541) to the cleaning hole (544), so that at least a portion of the water discharged from the cleaning hole (544) can be guided to be discharged to the rear of the guide body (541).

[0215] The above washing slit (545) can induce the water sprayed from the washing hole (544) to be sprayed evenly in a buoyant shape in a 90-degree area between the extension direction of the washing hole (544) and the extension direction of the main spray hole (541).

[0216] The above washing slit (545) may be provided to disperse water sprayed from the washing hole (545) at various angles.

[0217] As a result, the water sprayed from the washing hole (544) can spray water not only on the inner surface of the gasket (23) facing the washing hole (544), but also on various parts of the inner surface of the gasket (23) adjacent to the area facing the washing hole (544).

[0218] In addition, due to the washing slit (545), water sprayed from the washing hole (544) can wash both sides of the inlet (22) and the drum inlet (35), and can evenly wet the clothes contained in the drum body (31).

[0219] The above washing slit (545) may be formed so that its height or width becomes smaller as it approaches the washing hole (544) on the surface of the guide body (541). Accordingly, water flowing into the washing hole (544) through the washing slit (545) can be sprayed while being widely and evenly spread.

[0220] The lower surface of the above washing slit (545) may be arranged to be inclined so that the height decreases as it goes from the washing hole (544) to the surface of the guide body (541).

[0221] Accordingly, the water sprayed from the washing slit (545) does not entirely flow into the drum (30), but can be more reliably distributed from the gasket (23) to the rear of the door (230), the inlet (22), and the drum inlet (35). Accordingly, bubbles and foreign substances can be removed from the entire area from the gasket (23) to the rear of the door (230), the inlet (22), and the drum inlet (35).

[0222] Meanwhile, the washing slit (545) may be formed separately from the main injection hole (532). The main injection hole (542) may be spaced apart from the washing slit (545) to prevent water sprayed from the main injection hole (542) from being dispersed into the washing slit (545). Accordingly, the flow rate and pressure of water supplied from the main injection hole (542) to the rear of the drum (30) may be secured.

[0223] The above washing hole (544) may include a first washing hole (5441) that penetrates one side of the guide body (541) and is positioned on one side of the main injection hole, and a second washing hole (5442) that penetrates the other side of the guide body (541) and is positioned on the other side of the main injection hole.

[0224] The first cleaning hole (5441) and the second cleaning hole (5442) can be formed to be angled at an angle range of 90 degrees or more and 180 degrees or more. As a result, the nozzle unit (500) can evenly clean both sides of the installed gasket (23).

[0225] The above washing slit (545) may include a first washing slit (5451) that penetrates one side of the guide body (541) and is positioned on one side of the main injection hole, and a second washing slit (5451) that penetrates the other side of the guide body (541) and is positioned on the other side of the main injection hole.

[0226] The above washing slit (545) may include a first washing slit (5441) extending from the first washing hole (5441) to the surface of the guide body (541), and a second washing slit (5442) extending from the second washing hole (5442) to the surface of the guide body (541).

[0227] The angles of the first washing slit (5441) and the second washing slit (5442) may be formed differently from each other, and the cross-sectional areas may also be different from each other.

[0228] Accordingly, the spray unit (500) can be adjusted so that the flow rate and area of ​​water sprayed from the first washing slit (5441) and the second washing slit (5442) are as uniform as possible when the gasket (23) is installed with the spray unit (500) tilted to one side from the top. In addition, even if the spray unit (500) is installed at the top of the gasket (23), the spray direction of the water can be adjusted so that water is not sprayed into the air inlet hole (233).

[0229] The above washing slit (545) may be provided recessed from both sides of the main injection hole (542) to the blocking rib (550). As a result, water sprayed from the washing hole (544) can be sprayed more intensively toward the rear than the blocking rib (550).

[0230] As a result, the spray unit (500) may be configured to spray water intensively on an area facing rearward rather than the front surface of the gasket (23). That is, the cleaning flow rate can be secured intensively on areas where there is a high probability of foam or foreign substances sticking to the gasket (23) and the rear surface (230) of the door.

[0231] Meanwhile, the auxiliary injection hole (543) may be provided with a wider width than the main injection hole (542). In addition, since the auxiliary injection hole (543) is positioned higher than the main injection hole (542), the water sprayed from the auxiliary injection hole (543) may spread more widely as it goes downward.

[0232] Therefore, the auxiliary injection hole (543) can spray water over a wider area at the bottom of the drum (30).

[0233] Meanwhile, the interior of the auxiliary injection hole (543) may further include a partition rib (5431) that partitions the interior of the auxiliary injection hole (543).

[0234] The above partition rib (5431) may be arranged inside the auxiliary injection hole (543) to divide the sprayed water into various directions or may be provided to spray water evenly from the auxiliary injection hole (543).

[0235] The above partition ribs (5431) may be provided in multiple numbers and arranged at a certain distance apart along the width of the auxiliary injection hole (543).

[0236] The above partition rib (5431) can be arranged so that the width from one side of the auxiliary injection hole (531) to the partition rib (5431) is longer than the width between the partition ribs (5431).

[0237] Accordingly, more water can be supplied from the auxiliary injection hole (543) to both sides of the auxiliary injection hole (543) than to the center of the auxiliary injection hole (543).

[0238] Therefore, a larger amount of water than the main injection hole (542) can be sprayed on both sides of the lower part of the drum (30) to induce the clothes placed on the lower part of the drum (30) to be evenly wetted.

[0239] Fig. 9 illustrates an aspect in which water is sprayed from the spray unit of the present invention, and Fig. 10 illustrates the direction in which water is sprayed when the spray unit is installed on a gasket.

[0240] Specifically, Fig. 9(a) illustrates the injection unit (500) as viewed from below, and Fig. 9(b) illustrates the injection unit (500) as viewed from the side.

[0241] Referring to FIGS. 9 and 10, the injection unit (500) may be configured to spray water in at least one direction among the rear, rear both sides, and both sides in the installed area.

[0242] In addition, the above-mentioned injection unit (500) can spray water supplied from the inlet (510) to the entire area extending from both sides to the rear.

[0243] However, the above-mentioned injection unit (500) may not spray water forward.

[0244] The above injection unit (500) can be placed between the front surface of the gasket (23) and the rear surface of the gasket (23) on the upper side of the gasket (23).

[0245] For example, the injection unit (500) may be positioned closer to the front surface of the gasket (23).

[0246] In addition, the inner surface of the gasket (23) and the rear surface of the gasket (23) are more likely to be covered with bubbles or foreign substances than the front surface of the gasket (23).

[0247] In addition, the spray nozzle (540) of the spray unit (500) receives water through one inlet pipe (510), but is equipped to spray water through multiple discharge ports such as a main spray hole (542), an auxiliary spray hole (543), and a washing hole (544).

[0248] Therefore, spraying water to the front surface of the gasket (23) can unnecessarily reduce the quantity and flow rate of water sprayed to the main spray hole (542), auxiliary spray hole (543), and washing hole (544).

[0249] In addition, it may not be necessary to spray water on the front surface of the gasket (23) because it is difficult for bubbles or foreign substances to reach the rear surface (230) of the door.

[0250] In summary, the spray unit (500) of the present invention can be equipped to spray water intensively only toward the inner surface of the gasket (23) and the rear surface of the gasket (23), not the front surface of the gasket (23), so that the washing water sprayed from the main spray hole (542), the auxiliary spray hole (543), and the washing hole (544) can secure a water pressure and flow rate that can guarantee washing power.

[0251] Water (A) sprayed from the above auxiliary spray hole (543) can be sprayed toward the rear of the drum.

[0252] The water (B) sprayed from the main washing hole (542) can be sprayed toward the rear of the drum, but since the main washing hole (542) is arranged to be inclined downwards compared to the auxiliary spray hole (543), water can be sprayed to an area closer to the inlet (35) than the auxiliary spray hole (543).

[0253] In addition, water (B) sprayed from the main washing hole (542) can be dispersed in the rearward direction by the dispersion rib (5421). As a result, a portion of the water sprayed from the main washing hole (542) can be sprayed not only in the width direction of the lower portion of the drum (30), but also on the gasket (23) and the rear portion (230) of the door.

[0254] The water (C) sprayed from the above-mentioned washing hole (544) can be sprayed in both directions. Therefore, the water (C) sprayed from the above-mentioned washing hole (544) can wash the gasket (23).

[0255] In addition, a portion of the water (C) sprayed from the washing hole (544) may be sprayed in a fan shape in an area extending from the two sides (C) to the rear (A) through the washing slit (545).

[0256] That is, since the water (C) sprayed from the washing hole (544) is sprayed to the entire area from both sides to the rear by the washing slit (545), the quantity and water pressure per unit area of ​​the water discharged radially may be smaller than the quantity and water pressure of the water entering the washing hole (544) from the inlet pipe (510).

[0257] That is, since the water (C) sprayed from the washing hole (544) is dispersed over a 180-degree area from one side to the rear and the other side, it cannot be sprayed far, but can only be sprayed to an adjacent area and fall downward.

[0258] As a result, the water (C) sprayed from the washing hole (544) can be supplied intensively to the area near the spray nozzle (540).

[0259] Nevertheless, the water sprayed in a 180-degree area through the above-mentioned cleaning hole (544) can have a cleaning power sufficient to remove foam or foreign substances adhering to the gasket (23) and the rear part (230) of the door.

[0260] Therefore, the water (C) sprayed from the above-mentioned cleaning hole (544) can clean not only the gasket (23) but also the entire rear surface (230) of the door.

[0261] In addition, at least a portion of the water (C) sprayed from the washing hole (544) may be sprayed toward the front surface of the gasket (23). However, among the water (C) sprayed from the washing hole (544), water flowing toward the front surface or in both directions may be blocked by or come into contact with the blocking rib (550) and fall downwards due to gravity while moving along the extension direction of the blocking rib (550).

[0262] Among the water (C) sprayed from the above washing hole (544), water that falls downwards after being blocked by the blocking rib (550) can have the same effect as water sprayed downwards from the installation plate (520) if it falls due to gravity acceleration.

[0263] As a result, the water (C) sprayed from the washing hole (544) and coming into contact with the blocking rib (550) can wash the rear surface (230) of the door disposed at the lower portion of the installation plate (520). That is, the water (C) sprayed from the washing hole (544) can wash the entire area of ​​the rear surface (230) as it flows down from the upper portion to the lower portion of the rear surface (230).

[0264] As a result, the water (C) sprayed from the washing hole (544) can be concentrated and sprayed on the gasket (23) and the door (200), and can evenly wash from the top to the bottom of the inner surface of the gasket (23) and from the top to the bottom of the rear surface (230) of the door.

[0265] Figure 11 illustrates water being sprayed from the above-mentioned injection unit (500) with the gasket as the reference.

[0266] The above injection unit (500) can be coupled to the upper portion of the gasket (23) and can be placed between the front and rear surfaces of the gasket (23).

[0267] The above injection unit (500) can be coupled closer to the front surface than the rear surface of the gasket (23).

[0268] The water (A) sprayed through the auxiliary spray hole (543) can be sprayed toward the rear. That is, the water sprayed from the auxiliary spray hole (543) can be sprayed the furthest among the water sprayed from the spray nozzle (540).

[0269] Water (B) sprayed through the main injection hole (542) can be sprayed toward the lower rear portion. Therefore, the main injection hole (542) can spray water to an area closer to the drum inlet (35) than the auxiliary injection hole (543).

[0270] In addition, water (B) sprayed from the main injection hole (542) can collide with the dispersion rib (5421) disposed at the bottom and be dispersed to the left and right. Accordingly, while spraying toward the lower rear portion, it can also be sprayed to both sides.

[0271] The water (C) sprayed from the above-mentioned cleaning hole (544) can be sprayed toward the inner surface of the gasket (23) or toward both sides of the spray nozzle (540). Therefore, the cleaning hole (544) can be cleaned from both sides of the spray nozzle (540).

[0272] At this time, some of the water (C) sprayed from the washing hole (544) is sprayed toward the rear and lower rear portion through the washing slit (545), but due to the low water quantity and water pressure, it may not be able to leave the vicinity of the gasket (23). Therefore, the water (C) sprayed from the washing slit (545) may be supplied intensively to the rear portion (230) of the door, the inlet (22), or the drum inlet (25).

[0273] Figure 12 illustrates the effect of the cleaning hole of the present invention.

[0274] Referring to Fig. 12(a), water (C) sprayed from the cleaning hole (544) of the present invention can be sprayed directly toward both sides of the installed gasket (23). At this time, the water sprayed from the cleaning hole (544) can first collide with the inner surface of the gasket (23) located almost horizontally with the cleaning hole (544).

[0275] Referring to Fig. 12(b), water (C) sprayed from the cleaning hole (544) that collides with the inner surface of the gasket (23) moves downward along the inner surface of the gasket (23) and can sequentially wash away water attached to the inner surface of the gasket (23).

[0276] In addition, water (C) sprayed from the washing hole (544) can be inserted into at least some of the air inlet holes (233) to wash away bubbles or foreign substances that may have penetrated into the air inlet holes (233).

[0277] Meanwhile, the gasket (23) may further include a protrusion (244) that guides water (C) sprayed from the cleaning hole (544) to flow along the inner surface of the gasket (23). The protrusion (244) may be provided in a form in which water can be reflected to the lower part of the inner surface of the gasket (23) when water sprayed from the cleaning hole (544) collides with it.

[0278] The above protrusion (244) can be placed at a position facing the air inlet hole (233).

[0279] The water sprayed from the above-mentioned washing hole (544) can completely wash the inner surface of the gasket (23) and wash away all foam or foreign substances (E) adhering to the gasket (23) toward the lower part of the gasket (23) or the water contained in the tub (20).

[0280] Figure 13 illustrates an additional embodiment of the injection unit (500) of the present invention.

[0281] Fig. 13(a) illustrates the rear of an additional embodiment of the injection unit (500) of the present invention, and Fig. 13(b) illustrates the front of an additional embodiment of the injection unit (500) of the present invention.

[0282] Referring to Fig. 13(a), the rear structure of the injection unit (500) may be completely identical to the embodiment of the injection unit (500) described above.

[0283] That is, the above injection unit (500) may include an inlet pipe (510), a steam pipe (520), an installation plate (530), an injection nozzle (540), and a blocking rib (550).

[0284] The above injection nozzle (540) may include a guide body (541), a main injection hole (542), an exposed injection hole (543), the washing hole (544), and a washing slit (545).

[0285] Referring to Fig. 13(b), an additional embodiment of the injection unit (500) of the present invention may further include an additional washing hole (546) that sprays water to the front.

[0286] As described above, when water flowing in from the inlet pipe (510) is discharged to the additional cleaning hole (546), the flow rate sprayed into the main injection hole (542), the exposure injection hole (543), the cleaning hole (544), and the cleaning slit (545) may be reduced. In addition, the front surface of the gasket (23) may not require cleaning because it is difficult for foreign substances or bubbles to adhere to it.

[0287] However, if cleaning of the front surface of the gasket (23) is required depending on the shape and size of the gasket (23) and the rear surface of the door (230), the spray unit (500) may further include the additional cleaning hole (546).

[0288] The above additional cleaning hole (546) may be provided to penetrate the front of the guide body (541) so that water supplied from the inlet pipe (510) is sprayed toward the front of the gasket (23).

[0289] The additional cleaning hole (546) may be provided in any configuration and shape as long as it can spray water from the injection unit (500) to the front of the gasket (23). That is, the additional cleaning hole (546) may be provided so as to penetrate the guide body (541) from the front to the rear, or may be provided by recessing both sides of the guide body (541) like a cleaning slit (545).

[0290] For example, the additional cleaning hole (546) may be provided so as not to communicate with the main penetration hole (542) or the auxiliary penetration hole (543). This prevents water discharged through the main penetration hole (542) or the auxiliary penetration hole (543) from flowing out to the additional cleaning hole (546).

[0291] To this end, the additional cleaning hole (546) may be arranged spaced apart in at least one direction from the rear of the main penetration hole (542) or the auxiliary penetration hole (543).

[0292] The water sprayed from the additional cleaning hole (546) can be sprayed to the front of the gasket (23) or the rear surface (230) of the door. Therefore, in order for the additional cleaning hole (546) to be supplied to the entire front inner surface of the gasket (23) and the rear surface (230) of the door, the additional cleaning hole (546) can be arranged on both sides at the rear of the main penetration hole (542) or the auxiliary penetration hole (543).

[0293] In this way, water can be sprayed as evenly as possible toward both front sides from the spray unit (500), and bubbles or foreign substances that may adhere to the front surface of the gasket (23) and the top of the rear surface (230) of the door (200) can be washed away.

[0294] The above additional cleaning holes (546) may be provided on both sides of the main penetration hole (542) or the auxiliary penetration hole (543) of the guide body (541) by penetrating the guide body (541). A partition rib (5461) disposed in front of the main penetration hole (542) or the auxiliary penetration hole (543) may be included between the plurality of the above additional cleaning holes (546).

[0295] The additional washing hole (546) may be positioned in front of the blocking rib (550) and in the rear of the washing slit (545). That is, the additional washing hole (546) may be positioned symmetrically with the washing slit (545) with respect to the blocking rib (550).

[0296] Figure 14 illustrates the direction in which water is sprayed in an additional embodiment of the above spray unit (500).

[0297] Figure 14(a) illustrates the direction in which water is sprayed from the lower portion of the spray unit (500), and Figure 14(b) illustrates the direction in which water is sprayed from the side of the spray unit (500).

[0298] Referring to Fig. 14(a), water (A, B, C) sprayed from the main injection hole (542), auxiliary injection hole (543), and cleaning hole (544) among the injection nozzles (540) can be sprayed in the same direction as in the above-described embodiment. However, the flow rate or water pressure of water (A, B, C) sprayed from the main injection hole (542), auxiliary injection hole (543), and cleaning hole (544) can be reduced.

[0299] As the flow rate and water pressure of water (A, B, C) sprayed from the main injection hole (542), auxiliary injection hole (543), and washing hole (544) decrease, the flow rate and water pressure of water (D) sprayed from the additional washing hole (546) may increase.

[0300] The water (D) sprayed from the additional washing hole (546) can be sprayed forward from the spray unit (500).

[0301] The water (D) sprayed from the additional cleaning hole (546) above may be sprayed to both sides of the partition rib (5461). The gasket (23) facing the partition rib (5461) and the rear surface (230) of the door are likely to correspond to the uppermost part of the gasket (23) and the uppermost part of the rear surface (230) of the door, and the probability of foreign substances or foam being attached may be very low.

[0302] Accordingly, the water sprayed from the additional cleaning hole (546) can be sprayed to the uppermost part of the gasket (23) and the rear surface (230) of the door, except for the uppermost part, by the partition rib (5461). Accordingly, water can be sprayed to the part where there is a higher probability of bubbles or foreign substances among the front surface of the gasket (23) and the rear surface (230) of the door.

[0303] Referring to Fig. 14(b), water (D) sprayed from the additional cleaning hole (546) may collide with the front surface of the gasket (23) and the rear surface (230) of the door, and then flow down along the rear surface (230) of the door and enter the tub (20).

[0304] In this way, the rear surface (230) of the door can be cleaned more reliably.

[0305] Figure 15 illustrates water being sprayed from the spray unit (500) of the above additional embodiment, with the gasket as a reference.

[0306] Since the water (D) sprayed from the above additional cleaning hole is sprayed intensively on the front surface of the gasket placed in front of the spray unit (500), the effect of cleaning the inner surface of the gasket (23) may not be great.

[0307] However, since the water (D) sprayed from the additional washing hole inevitably collides with the rear surface (230) of the door, the rear surface (230) of the door can be washed with a greater flow rate.

[0308] Meanwhile, in the injection unit (500) of the above additional embodiment, the direction (A, B, C) of water sprayed from the main injection hole (542), auxiliary injection hole (543), and washing hole (544) may be the same as when the additional washing hole (546) is not provided, but the flow rate may be smaller than when the additional washing hole (546) is not provided.

[0309] Accordingly, in the garment treatment device of the present invention, if it is necessary to wash the rear surface (230) of the door or if washing the front surface of the gasket (23) is important, the spray unit (500) may be provided with an additional washing hole (546). However, in the garment treatment device of the present invention, if it is important to wash the inner surface of the gasket (23) and the wetting depth of the clothes accommodated in the drum (30) of the door, the additional washing hole (546) of the spray unit (500) may be omitted. As described above, even if the additional washing hole (546) of the spray unit (500) is omitted, the rear surface (230) of the door can be washed.

[0310] The present invention may be implemented in various modified forms, and the scope of the invention is not limited to the above-described embodiments. Therefore, if a modified embodiment includes elements of the claims of the present invention, it should be considered to fall within the scope of the present invention.
