Description

Technology Field

[0001] The present invention relates to a garment processing device, and more specifically, to a garment processing device capable of performing refresh operations such as sterilization, wrinkle removal, deodorization, and drying of garments. Background Technology

[0002] Generally, a clothing treatment device is a home appliance that removes foreign substances from clothing using water and detergent, and includes a tub for storing water, a water supply unit for supplying water to the tub, and a detergent supply unit disposed on a path connecting the water supply unit and the tub to supply detergent to the tub together with the water.

[0003] Conventional clothing processing devices supplied detergent in a manner where the detergent supply unit was connected to the water supply unit, and when water was supplied to the tub, the detergent stored in the detergent supply unit and water were supplied together to the tub.

[0004] While these conventional garment processing devices could guarantee users the autonomy to select the type and amount of detergent required, there was a fundamental problem in that it was difficult to expect the appropriate amount of detergent to be injected.

[0005] In addition, this garment processing device had the inconvenience of requiring new detergent to be added every time washing was performed, because all the detergent stored in the detergent supply unit was supplied to the tub when the detergent supply unit received water.

[0006] In addition, these garment processing devices had a problem where the clothes were damaged due to direct contact with highly concentrated detergents that were not completely mixed.

[0007] To overcome this, a garment processing device has emerged in which the detergent supply unit is controlled by a control unit provided in the garment processing device to supply an appropriate amount of detergent. (Refer to Korean Patent Publication No. 2008-0089086)

[0008] The above-described conventional clothing processing device is configured to indirectly introduce detergent into the tub by supplying detergent to a liquid detergent mixing section provided in a bellows that connects the tub and the circulation mechanism, thereby supplying the detergent supplied to the bellows and the water discharged from the tub back to the tub through the circulation mechanism.

[0009] However, since the aforementioned conventional clothing processing device is equipped with a liquid detergent mixing unit in the pipe through which water stored in the tub is discharged and is configured to supply liquid detergent to the mixing unit, vibrations from the tub are transmitted directly to the mixing unit, resulting in a problem where the supply of liquid detergent is vulnerable to vibrations.

[0010] In addition, there exists a garment processing device that supplies a first detergent and a second detergent to a tub by connecting a first detergent supply pipe for supplying a first detergent and a second detergent supply pipe for supplying a second detergent to a first connecting pipe through which water from the tub is discharged, respectively, thereby supplying the detergents. (Refer to Korean Patent Publication No. 2021-0060386)

[0011] The aforementioned conventional clothing processing device had a problem in that both the first and second detergents were provided in the first connecting pipe, making the first and second detergent connecting pipes vulnerable to vibrations generated in the tub. Additionally, since both the first and second detergents were supplied to the first connecting pipe, where water is rapidly discharged, there was a problem in that detergents could remain in the first connecting pipe because they could not be sufficiently mixed with water. The problem to be solved

[0012] The present application aims to solve the problem of providing a structure in which a detergent supply unit supplying detergent in a clothing processing device can be minimized from the influence of vibrations generated in a tub.

[0013] The present application aims to solve the problem of providing a structure in which a detergent pipe is connected to a housing portion spaced apart from a tub, thereby minimizing the influence of vibrations generated in the tub on the detergent pipe, and preventing the detergent from leaking due to the connection of the detergent pipe being released or ruptured.

The front panel (110) may be equipped with a control panel (not shown) so that the user can easily control the clothing processing of the clothing processing device (1).

[0045] The front panel (110) may include a door panel (120) having an input opening (125, see FIG. 2) at the front and a supply panel (140) provided below the door panel (120). Additionally, the front panel (110) is provided with a door (130) that allows the input opening (125) to be opened and closed.

[0046] The door panel (120) is provided with an input port (125) so that clothing can be fed into the interior of the cabinet (100). The door panel may be provided with a control panel (not shown) into which commands to control clothing processing of the clothing processing device (1) are input. Since the control panel is provided in front of the cabinet (100) equipped with the input port, the user can easily operate both the input of clothing and the processing of clothing to perform clothing processing, thereby increasing convenience.

[0047] The supply panel (140) may be located below the door panel (120). The door panel (120) may be equipped with a device that is used relatively infrequently by the user. For example, the door panel (120) may be equipped with a detergent supply, a lint filter, etc., and may be equipped with a device necessary for the maintenance and repair of the clothing processing device (1).

[0048] That is, the door panel (120) may be equipped with a device that is frequently used by the user, and the supply panel (140) may be equipped with a device that is relatively frequently used by the user.

[0049] The supply panel (140) may be provided with a through hole (not shown) so that at least a portion of the detergent drawer (415) of the detergent supply unit (400, see FIG. 2) or the filter unit (390) of the pump unit (300, see FIG. 2) may be exposed to the outside of the supply panel (140).

[0050] The supply panel (140) may be provided with a supply cover (145) that blocks the supply panel to protect and cover the detergent drawer (415) or filter section (390) exposed to the outside.

[0051] The supply panel (140) may be recessed further back (in the -X direction) than the door panel (120), and the supply cover (145) may be provided to cover the supply panel (140) by the recessed portion. In this case, when the supply cover (145) covers the supply cover, the front surface of the supply cover (145) is provided such that the height difference between it and the front surface of the door panel (120) is minimized, thereby improving the overall sense of unity and aesthetic appeal of the front panel (110).

[0052] FIG. 2 is a perspective view showing the interior of a clothing processing device according to one embodiment of the present invention.

[0053] As illustrated in FIG. 2, a clothing processing device (1) according to one embodiment of the present invention may include a drum (150) rotatably provided inside the cabinet (100), a tub (170) that accommodates the drum and stores water, a pump unit (300) that communicates with the tub and receives water discharged from the tub, and a detergent supply unit (400) that supplies detergent to the tub or the pump unit.

[0054] The drum (150) may be rotatably provided inside the tub (170) by a driving unit (155). The front of the drum (150) is open to communicate with an inlet (125) so as to receive clothing inserted through the inlet (125). The drum (150) may rotate by the driving unit (155) to perform processing of the clothing.

[0055] The drum (150) is provided with a drum hole (151). The drum (150) allows external water to flow in through the drum hole (151) to mix water and clothing, and allows internal water to be discharged to the tub (170) through the drum hole (151).

[0056] One side of the drive unit (155) is connected to the rear of the cabinet and the other side penetrates the rear of the tub (170) and is connected to the rear of the drum (150) to rotate the drum.

[0057] The tub (170) has an open front so that the drum (150) can be accommodated inside and can store water supplied from the outside. Both the opening at the front of the tub (170) and the inlet (125) at the front of the drum can be connected to the inlet (125), and a gasket (not shown) can be provided to prevent water leakage.

[0058] The tub (170) can be supported inside the cabinet (100) by a support member (175). The support member (175) can not only support the tub (170) inside the cabinet, but can also include a damping device to offset vibrations of the tub caused by the rotation of the drive member.

[0059] The pump unit (300) is connected to the tub (170) so that water discharged from the tub flows in, and can supply the inflowed water back to the tub (170) or discharge water to the outside of the cabinet (100).

[0060] The pump unit (300) may be provided so that water discharged from the tub (170) and detergent supplied from the detergent supply unit (400) can be introduced to mix the water and detergent. The pump unit (300) may resupply the detergent solution mixed with water and detergent to the tub (170).

[0061] More specifically, the pump unit (300) may include a housing unit (310, see FIG. 6) into which water discharged from the tub (170) flows and which forms the exterior of at least part of the pump unit (300), a circulation pump (330, see FIG. 6) provided in the housing unit (310) to flow the water flowing into the housing unit (310) back to the tub (170) and resupply it, and a drainage pump (350, see FIG. 6) to discharge the water flowing into the housing unit (310) to the outside.

[0062] The pump unit (300) is equipped with the filter unit (390) to filter out foreign substances or lint remaining in the water introduced from the tub. The filter unit (390) is provided such that at least a portion of it is exposed to the supply panel (140) and is provided to be able to be withdrawn in the forward and backward directions from the pump unit (300), so that the user can easily remove foreign substances and lint collected in the filter unit (390) by withdrawing the filter unit (390) without disassembling the cabinet (100).

[0063] The pump unit (300) can be connected to the tub through the tub drain pipe (211) and the tub circulation pipe (213), and water can be discharged to the outside of the cabinet (100) through the pump drain pipe (215).

[0064] The above tub drain pipe (213) can connect the tub and the pump unit (300) so that water discharged from the tub (170) flows to the pump unit (300).

[0065] The above tub circulation pipe (213) can connect the pump unit (300) and the tub (170) so that water supplied from the pump unit (300) flows into the tub (170) by the circulation pump (330, see FIG. 3).

[0066] The above pump drain pipe (215) may be configured to communicate with the outside of the pump unit (300) so that water flowing into the pump unit (300) is discharged to the outside of the cabinet (100) through the drain pump (350, see FIG. 3).

[0067] The detergent supply unit (400) may include a detergent case (410) that is connected to the rear of the supply panel (140) and has an open front, and a detergent drawer (415) that is configured to be drawn out in the forward and backward directions from the open front of the detergent case (410). The detergent drawer (415) may be equipped with a detergent storage unit (430, see FIG. 3).

[0068] The above detergent supply unit (400) may include a detergent pump (440, see FIG. 6) that flows the detergent stored in the detergent storage unit (430) to the outside of the detergent storage unit (430).

[0069] The detergent supply unit (400) can supply the detergent stored in the detergent storage unit (430) to the tub (170) or the pump unit (300). The detergent supply unit (400) of the present invention is equipped with a detergent pump (440, see FIG. 3) to supply the detergent stored in the detergent storage unit (430) to the tub (170) or the pump unit (300). Preferably, the detergent supply unit (400) can be equipped to supply the detergent to the pump unit (300) to simplify the piping of the detergent pipe (450, see FIG. 3) and to ensure the stability of the connection.

[0070] Additionally, the detergent supply unit (400) and the pump unit (300) may be connected to allow the detergent discharged by the detergent pump (440) to flow to the pump unit (300), and the detergent pipe (450, see FIG. 6) may be further included.

[0071] More specifically, the detergent pipe (450) may be configured to connect the detergent supply unit (400) to one or more of the tub (170), tub drain pipe (211), tub circulation pipe (213), and pump unit (300) so that the detergent stored in the detergent supply unit (400) is directly supplied to one or more of the above.

[0072] At this time, if the detergent pipe (450) is connected to the tub (170) or the tub drain pipe (211) or tub circulation pipe (213), vibrations generated in the tub (170) during the clothing processing process may be directly transmitted to the detergent pipe (450). In this case, the bonding strength of the detergent pipe (450) may be reduced, or the sealing part may rupture, causing the detergent inside to leak out. Alternatively, due to the vibrations applied to the detergent pipe (450), foam may form in the detergent flowing through the detergent pipe (450), potentially reducing the reliability of the detergent supply.

[0073] The detergent pipe (450) of the present invention can minimize the propagation of vibrations generated in the tub (170) to the detergent pipe (450) by connecting the detergent supply unit (400) to the pump unit (300), preferably the housing unit (310).

[0074] Specifically, vibrations generated in the tub (170) are primarily attenuated by the support member (175) and secondarily attenuated by the bellows portion that may be formed in the tub drain pipe (211) or the tub circulation pipe (213), thereby minimizing vibrations to be applied to the pump unit (300). Additionally, the pump unit (300) may be coupled to a base (190, see FIG. 6) provided on the bottom surface of the cabinet (100), and vibrations may be tertiarily attenuated by the base (190).

[0075] That is, by connecting the detergent pipe (450) to the pump section (300) where the vibration of the tub is attenuated to the maximum extent and supplying the detergent, the reliability of the detergent supply of the detergent supply section (400) by the detergent pipe (450) can be improved.

[0076] Meanwhile, the detergent storage unit (410) may include a first detergent storage unit (411, see FIG. 10) for storing a first detergent and a second detergent storage unit (412, see FIG. 10) for storing a second detergent.

[0077] Here, either the first detergent or the second detergent may be a laundry agent used in the washing process of a garment processing device, and the other may be a fabric softener used in the rinsing process of a garment processing device. However, the first detergent and the second detergent of the present invention are not limited thereto and may be a laundry agent or a fabric softener having the same chemical composition.

[0078] The detergent pump (440) may include a first detergent pump (441, see FIG. 6) provided in the first detergent storage unit (411) to discharge a first detergent and a second detergent pump (442, see FIG. 6) provided in the second detergent storage unit (442) to discharge a second detergent.

[0079] The detergent pipe (450) may include a first detergent pipe (451, see FIG. 6) that is connected to the first detergent pump (441) to supply a first detergent, and a second detergent pipe (452, see FIG. 6) that is connected to the second detergent pump (442) to supply a second detergent.

[0080] The first detergent pipe (451) and the second detergent pipe (452) can connect the detergent storage unit (410) and the pump unit (300) to supply the first detergent and the second detergent to the pump unit (300), respectively.

[0081] Meanwhile, it should be understood that the clothing processing device (1) of the present invention is not limited to the type of detergent introduced or the number of detergent pipes (450).

[0082] That is, the detergent pipe of the present invention can be provided with a plurality of detergent pipes (450) as well as a first detergent pipe (451) and a second detergent pipe (452), and can also be provided with a single detergent pipe (450).

[0083] Additionally, the detergent supply unit (400) of the present invention is located below the tub (170), but is not limited thereto and may be located above the tub (170).

[0084] The detergent supply unit (400) of the present invention is exemplified by an automatic detergent supply unit in which an appropriate amount of detergent is automatically supplied at the appropriate time by a control unit, but is not necessarily limited thereto and may also be a manual detergent supply unit in which detergent is supplied to a tub (170) together with water supplied from the outside. In addition, the present invention may be a clothing processing device equipped with both an automatic detergent supply unit and a manual detergent supply unit.

[0085] The supply of detergent and the circulation of water of the detergent supply unit (400) will be described later.

[0086] Figure 3 is a diagram showing the movement of water and detergent in the clothing processing device of the present invention.

[0087] Referring to FIG. 3, water discharged from the tub (170) flows into the housing (310) of the pump unit (300) through the tub drain pipe (211). The water flowing into the housing (310) can be supplied back to the tub (170) through the tub circulation pipe (213) by the circulation pump (330). That is, the tub drain pipe (213), the housing (310), and the circulation pipe can be defined as a “circulation path” through which water inside the tub (170) circulates.

[0088] Additionally, water flowing into the housing part (310) can be discharged to the outside of the cabinet through the pump drain pipe (215) by the drain pump (450). That is, the tub drain pipe (211), the housing part (310), and the pump drain pipe (215) can be defined as a “drainage channel” through which water inside the tub (170) is discharged to the outside.

[0089] In order to improve the reliability of water circulation through the above circulation path and the above drainage path, the circulation pump (330) and the drainage pump (350) are controlled by a control unit (not shown) so that when one pump operates, the other one can be stopped from operating.

[0090] Additionally, the detergent stored in the detergent storage unit (430) of the detergent supply unit (400) can be discharged to the outside of the detergent storage unit (430) by the detergent pump (440) and supplied to the pump unit (300), preferably the housing unit (310), through the detergent pipe (450). That is, the detergent storage device (400), the detergent pipe (450), the housing unit (310), and the tub circulation pipe (213) can be defined as a “detergent supply path.” That is, the detergent supply unit (400) can supply detergent to the tub (170) through the detergent supply path.

[0091] Meanwhile, as described above, the housing portion (310) may form a space in which water flowing in from the tub drain pipe (213) and detergent flowing in from the detergent pipe (450) are introduced and mixed. After the water and detergent are mixed in the housing portion (310) to form a washing liquid, the washing liquid is supplied to the tub (170) through the tub circulation pipe (213), thereby allowing the detergent to be supplied to the tub (170) at a uniform concentration compared to the case where the detergent is supplied directly to the tub (170).

[0092] In other words, if the detergent is supplied directly to the tub (170), the detergent, which is not completely mixed with water, comes into contact with the clothing inside the drum (150), and there is a risk that the clothing may be damaged depending on the material of the clothing, and the clothing may trap the detergent, causing the concentration of the detergent inside the tub to become uneven.

[0093] Accordingly, the present invention can increase the efficiency of clothing processing by supplying water and detergent together to the housing part (310) of the pump part (300), mixing them, and then supplying them to the tub (170).

[0094] FIG. 4 is a block diagram showing that clothing treatment is performed according to one embodiment of the present invention.

[0095] Referring to FIG. 4, the garment processing of a garment processing device (1) according to one embodiment of the present invention may include the steps of detecting the amount of garments introduced into the drum (150) (S10), supplying a detergent (S20), performing a washing process during garment processing by rotating the driving unit (155) according to a predetermined algorithm (S30), rinsing the garments contained in the drum (150) first (S40), supplying a fabric softener through the detergent supply unit (400), rinsing the garments contained in the drum (150) secondarily (S60), and draining the water contained inside the tub (170) and dehydrating the garments (S70).

[0096] Although not shown in the drawing, the steps before and after the washing process (S30), first rinse (S40), and second rinse (S60) may include a step of supplying water to the tub (170) and a step of discharging water from the tub.

[0097] The above volume detection step (S10) can measure the volume (weight) of the clothing contained inside the drum (150) by the difference in current values ​​detected by rotating the driving unit (155). Depending on the measured volume, the values ​​of the first detergent amount and the second detergent amount, which will be described later, may be predetermined.

[0098] The laundry agent supply step (S20) is a step of supplying a detergent used in the laundry process (S30). It may include a step (S21) in which a circulation pump (330) is operated, a step (S23) in which a first detergent supply amount is determined based on the measured amount value by a control unit (not shown), and a step (S25) in which the first detergent pump (441) is operated to supply the first detergent to the housing unit (310).

[0099] Here, the order in which the first and second detergents are added is irrelevant. That is, unlike the drawing, the detergent supply step (S20) may be a step in which the second detergent pump (442) operates to add the second detergent.

[0100] In addition, the above-mentioned circulation pump operation step (S21) and detergent amount determination step (S23) may be provided in reverse order; that is, the invention is considered to apply as long as the first detergent injection step (S25) is the last step of the laundry agent supply step (S20).

[0101] In the first rinse (S40), external water is supplied without supplying detergent, and the drive unit (155) can be rotated by the control unit according to a predetermined algorithm.

[0102] The fabric softener supply step (S50) may include the steps of operating a circulation pump (S51), determining a preset amount of second detergent based on the amount of detergent measured in the amount detection step (S10) (S53), and supplying the second detergent by the second detergent pump (442) according to the determined amount of detergent.

[0103] In the fabric softener supply step (S50), the first detergent may be supplied, or a detergent identical to the first detergent may be supplied. Additionally, in the fabric softener supply step (S50), only the second detergent needs to be supplied, and the order of the circulation pump operation step (S51) and the detergent amount determination step (S53) may be changed.

[0104] As described above, the time at which the first detergent and the second detergent are supplied by the detergent supply unit (400) may differ. Alternatively, the first detergent and the second detergent may be supplied at once in the laundry detergent supply step (S20) and the fabric softener supply step (S50).

[0105] FIG. 5 is a view of the detergent supply unit (400) and the pump unit (300) from the rear, looking at the bottom of the cabinet (100).

[0106] Referring to FIG. 5, the cabinet (100) may include a base (190) provided at the bottom, which provides a space for installing various equipment.

[0107] The detergent supply unit (400) and the pump unit (300) can be coupled to the base (190). The detergent supply unit (400) and the pump unit (300) are provided in the rear direction (-X-axis direction) of the supply panel (140) so that at least a portion of them can be exposed to the outside when the supply cover (145) is opened.

[0108] Additionally, the detergent supply unit (400) and the pump unit (300) may be connected through a detergent pipe (450). The detergent supply unit (400) and the pump unit (300) may be provided adjacent to reduce the extension length of the detergent pipe (450) and simplify the pipe structure.

[0109] Specifically, the detergent supply unit (400) is provided adjacent to the first panel among the panels forming both sides (Y-axis) of the cabinet (100), and the pump unit (300) is provided adjacent to the second panel facing the first panel among the panels forming both sides of the cabinet (100), so that they can be arranged side by side in the width direction of the cabinet.

[0110] The housing part (310) of the pump part (300) is positioned below the tub (170) and can be connected to the tub drain pipe (213), tub circulation pipe (213), pump drain pipe (215) and detergent pipe (450).

[0111] In other words, to simplify the piping relationship of each pipe connected to the housing part (310) of the pump part, the detergent supply part (400) and the pump part (300) can be provided side by side in the width direction below the tub (170).

[0112] Through this structure, not only can vibrations generated in the tub be minimized from propagating to the detergent pipe (450), but the pipe structure can also be simplified.

[0113] Meanwhile, the first detergent pipe (451) and the second detergent pipe (452) of the detergent pipe (450) can be connected to different locations in the housing part (310).

[0114] The connection relationship between the detergent pipe (450) and the housing part (310) will be described later.

[0115] Hereinafter, the pump unit (300) according to the first to third embodiments is described, but this is merely to explain in detail the connection relationship between the pump unit (300) and the detergent pipe (450), and it should be understood that the present invention is not limited to each embodiment described below.

[0116] FIG. 6 is a rear perspective view of the pump unit (300a) according to the first embodiment.

[0117] Referring to FIG. 6, the pump unit (300a) according to the first embodiment may include a housing unit (310) in which a space for fluid flow is formed and connected to a tub pipe (211, 213), a pump drain pipe (215), and a detergent pipe (450); a circulation pump (330) provided in the housing unit (310) to re-supply water flowing into the housing unit (310) to the tub (170); a drain pump (350) provided in the housing unit (310) to discharge water flowing into the housing unit (310) to the outside; and a filter unit (390, see FIG. 8) provided inside the housing unit (310) to filter foreign substances or lint.

[0118] The housing section (310) may include a water collection housing (311) into which water discharged from the tub (170) flows and to which the tub drainage pipe (213) is connected, a circulation housing (313) that is in communication with the water collection housing (311) and provides a space to which the circulation pump (330) is connected, and a drainage housing (315) that is in communication with the water collection housing (311) and provides a space to which the drainage pump (350) is connected.

[0119] Additionally, the housing part (310) may include a housing port (361, 363, 365) that provides a space connected to the tub pipe (211, 213) and the pump drain pipe (215), and a detergent port (371, 372) to which the detergent pipe (450) is connected and through which the detergent is introduced.

[0120] Housing ports (361, 363, 365) may protrude outside the housing portion. Housing ports (361, 363, 365) may include a water collection port (361) provided in the water collection housing (311) and connected to the tub drainage pipe (211) to allow water stored in the tub to flow in, a circulation port (363) provided in the circulation housing (313) to allow water or detergent introduced into the interior of the circulation housing (313) by the circulation pump (330) to be discharged to the tub circulation pipe (213), and a drainage port (365) provided in the drainage housing (315) to allow water introduced into the interior of the drainage housing (315) by the drainage pump (350) to be discharged to the pump drainage pipe (215).

[0121] As shown in the drawing, the water collection port (361) can be extended to the rear of the housing part (310). Through this, water flowing into the tub drain pipe (211) strikes the front of the water collection housing (311) once, forming an irregular water flow inside, thereby improving the efficiency of mixing with the detergent flowing in through the detergent pipe.

[0122] Additionally, for simplification of piping, the water collection port (361) and the drainage port (365) may be provided side by side. Preferably, the water collection port (361) and the drainage port (365) may be formed extending to the rear of the housing portion (310).

[0123] The circulation port (363) may be provided so as not to face the circulation hole (3113, see FIG. 9) of the water collection port (361) and the water collection housing (311).

[0124] In other words, since the fluid flow angle changes while the water flowing into the collection housing (311) by the collection port (361) passes through the circulation housing (313) and the circulation port (363), the mixing efficiency between the water and the detergent can be improved.

[0125] Preferably, the water collection port (361) is positioned to extend to the rear of the water collection housing (311), the circulation housing (311) is positioned to extend to the side of the water collection housing (311), and the circulation port (363) can be provided to extend to the upper side of the water collection housing (311).

[0126] The detergent ports (371, 372) may be formed to protrude outside the housing portion (310). The detergent ports (371, 372) may include a first detergent port (371) connected to the first detergent pipe (451) and a second detergent port (372) connected to the second detergent pipe (452).

[0127] In the pump unit (300a) according to the first embodiment, the first detergent pipe (451) is connected to the water collection housing (311), and the second detergent pipe (452) is provided in the circulation housing (313) so as to be positioned downstream of the circulation pump (330).

[0128] The first detergent port (371) is preferably extended in a vertical direction so as not to be parallel to the water collection port (361), and the second detergent port (372) is preferably extended in a vertical direction so as not to face the circulation port (363) and the circulation hole (3113).

[0129] Additionally, the first detergent port (371) is positioned to extend upward from the water collection port (361) or water collection housing (311), and the second detergent port (372) can extend backward from the circulation port (363) or circulation housing (313).

[0130] FIG. 7 is a cross-sectional view according to 1-1' of FIG. 6, FIG. 8 is a cross-sectional view according to 2-2' of FIG. 6, and FIG. 9 is a cross-sectional view according to 3-3' of FIG. 6. A pump section (300a) according to the first embodiment will be described with reference to FIG. 7 to 9.

[0131] FIG. 7 is a cross-sectional view of the circulation housing (313). As described above, the circulation housing (313) may provide a space equipped with a circulation pump (330) to discharge water flowing into the water collection housing (311).

[0132] That is, at least a part of the circulation pump (330), preferably the circulation impeller (3331) of the circulation pump (330), is provided inside the circulation housing (313) so that water introduced into the circulation housing (311) can flow through the circulation housing (313) and the circulation port (363) to the tub circulation pipe (213).

[0133] The above circulation housing (313) may be equipped with a circulation port (363) through which water is discharged, and a second detergent port (372) provided in the circulation port (363) or the circulation housing (313). Water introduced through the water collection housing (311) flows into the circulation housing (313) through the circulation hole (3113).

[0134] In addition, the circulation housing (313) is equipped with a second detergent port (372) so that the second detergent can be introduced into the interior of the circulation housing (313).

[0135] Water and detergent introduced into the circulation housing (313) are mixed in the internal space of the circulation housing (313) and discharged together through the circulation port (363) to the tub circulation pipe (213) by the circulation impeller (3331) and supplied to the tub (170).

[0136] The second detergent port (372) can preferably be positioned vertically so as not to face the circulation port (363). By positioning it in this way, the angle between the flow direction of the water discharged to the circulation port (363) and the flow direction of the detergent flowing into the second detergent port (372) is maximized, thereby allowing the water and detergent to be mixed more effectively.

[0137] Additionally, a check valve (375) may be provided in the second detergent pipe (452) or the second detergent port (372). The check valve is provided to allow only the movement of fluid from the detergent supply unit (400) toward the pump unit (300) and to block the movement of fluid from the pump unit (300) toward the detergent supply unit (400).

[0138] Additionally, the check valve (375) may be provided not only in the second detergent pipe (452) or the second detergent port (372), but also in the first detergent pipe (451) or the first detergent port (371).

[0139] In the drawing, the second detergent port (372) is provided in the circulation housing (313) as an example, but the case where the first detergent port (371) is provided in the circulation housing (313) and the second detergent port (372) is provided in the water collection housing (311) is also considered to belong to the pump unit (300a) of the first embodiment of the present invention.

[0140] FIG. 8 is a cross-sectional view of a water collection housing (311). Referring to FIG. 8, the water collection housing (311) is equipped with a water collection port (361) and a first detergent port (371), and a space is formed inside through which fluid can flow.

[0141] That is, the water collection housing (311) can receive water introduced from the tub drain pipe (211) through the water collection port (361) and detergent introduced from the first detergent pipe (451) through the first detergent port (371).

[0142] As described above, the first detergent port (371) and the water collection port (361) are provided so as not to face each other, so that the flow direction of water flowing in from the water collection port (361) and the flow of detergent flowing in from the first detergent port (371) are staggered, preferably arranged vertically, thereby preventing the highly concentrated detergent from settling and improving the mixing efficiency with water.

[0143] Additionally, the first detergent port (371) or the first detergent pipe (451) is equipped with a check valve (375) to allow the movement of fluid from the detergent supply unit (400) to the water collection housing (311) and to block the movement of fluid from the water collection housing (311) to the detergent supply unit (400).

[0144] Additionally, the water collection housing (311) may be the first space into which water discharged from the tub (170) flows into the pump unit (300), and foreign matter or lint discharged from the tub (170) may also flow in.

[0145] Accordingly, a filter unit (390) may be provided in the water collection housing (311) of the pump unit (300) of the present invention. At least a portion of the filter unit (390) is disposed in the internal space of the water collection housing (311) so as to be able to be withdrawn from the water collection housing (311).

[0146] The filter unit (390) may include a filter handle (391) positioned outside the water collection housing (311) and exposed to the supply panel (140), a filter member (393) extending from the filter handle (391) to the rear of the water collection housing (311) and configured to filter foreign substances or lint, and a filter sealing (395) that seals the space between the filter member (393) or the filter handle (391) and the water collection housing (311) to prevent water from leaking out.

[0147] The user can open the supply cover (145), grasp the filter handle (391) exposed through the supply panel (140), and pull it forward to separate the filter unit (390) from the water collection housing (311).

[0148] The user can wash the separated filter unit (390) or replace the filter unit (390), and then push the filter unit (390) back into the supply panel (140) to mount the filter unit (390) in the water collection housing (311).

[0149] FIG. 9 is a cross-sectional view of the filter section (300a). Referring to FIG. 9, a circulation housing (313) may be provided on one side of the water collection housing (311), and a drainage housing (315) may be provided on the other side of the water collection housing (311).

[0150] The circulation pump (330) may include a circulation pump case (331) that forms the exterior of at least a part of the circulation pump, and a circulation motor part (333) provided inside the circulation pump case (331).

[0151] The above circulation pump case (331) is provided to accommodate at least a portion of the circulation motor unit (333) inside and can be coupled with the circulation housing (313). That is, the circulation housing (313) is provided in a form in which one side facing the water collection housing (311) is open, and the circulation pump case (331) can be provided to cover the open portion.

[0152] The above-mentioned circulation motor part (333) may be provided such that at least one part is accommodated in the circulation pump case (331), and the remaining part is accommodated in the circulation housing (313).

[0153] The above circulation motor unit (332) may include a circulation impeller (3331) rotatably provided in the circulation housing (313), a circulation motor (3333) housed in the circulation pump case (331) to generate driving force, and a rotating shaft (3332) that connects the circulation motor (3333) and the circulation impeller (3331) to transmit the driving force of the circulation motor (3333) to the circulation impeller (3331).

[0154] The drainage pump (350) may include a drainage pump case (351) that forms the exterior of at least part of the circulation pump, and a drainage motor part (353) provided inside the drainage pump case (351).

[0155] The drainage pump case (351) is configured to accommodate at least a portion of the drainage motor unit (353) inside and can be coupled with the drainage housing (315). That is, the drainage housing (315) is configured with one side facing the water collection housing (311) open, and the drainage pump case (351) can be configured to cover the open portion.

[0156] The above drainage motor part (353) may be provided to be at least accommodated in the drainage pump case (351), and the remaining part accommodated in the drainage housing (315).

[0157] The above drainage motor unit (353) may include a drainage impeller (3531) rotatably provided in the drainage housing (315), a drainage motor (3533) housed in the drainage pump case (351) to generate driving force, and a rotating shaft (3352) that connects the drainage motor (3533) and the drainage impeller (3531) to transmit the driving force of the drainage motor (3533) to the drainage impeller (3531) and rotate it.

[0158] The above water collection housing (311) may be connected to the circulation housing (313) and the drainage housing (315), respectively. More specifically, the circulation housing (313) may be provided on one side of the water collection housing (311) and may include a circulation hole (3113) that communicates with the circulation housing (313). Additionally, the drainage housing (315) may be provided on the other side of the water collection housing (311) and may include a drainage hole (3115) that communicates with the drainage housing (315).

[0159] In other words, water flowing into the collection housing (311) through the tub drainage pipe (211) can be configured to move to the circulation housing (313) through the circulation hole (3113) or to the drainage housing (315) through the drainage hole (3115).

[0160] In addition, the detergent flowing in through the first detergent pipe (451) can also move to the circulation housing (313) through the circulation hole (3113).

[0161] The above circulation hole (3113) is provided to connect the water collection housing (311) and the circulation housing (313), and preferably, its diameter is smaller than the diameter of the water collection housing (311) or the circulation housing (313).

[0162] By being formed with such a size, the pressure increases as the water and detergent flowing into the water collection housing (311) pass through a narrow passage (circulation hole (3113)), and as a result, the mixing efficiency of the water and detergent can be increased.

[0163] Meanwhile, although the present invention has been exemplified by the housing part (310), the circulation pump case (331), and the drainage pump case (351) being combined to form the overall exterior of the pump part (300), it should be understood that the present invention is not limited thereto and may be implemented in a structure in which the housing part (310), the circulation pump (330), and the drainage pump (350) are each separated and spaced apart and connected by separate pipes.

[0164] FIG. 10 is a diagram showing the circulation of water and detergent according to the first embodiment of the pump section.

[0165] Referring to FIG. 10, water discharged from the tub (170) flows into the water collection housing (311) through the tub drainage pipe (211), and the first detergent stored in the first detergent storage unit (431) also flows into the water collection housing (311) through the first detergent pipe (451).

[0166] The water and the first detergent flowing into the above water collection housing (311) are introduced into the circulation housing (313) by the flow generated by the circulation pump (330). Additionally, the second detergent stored in the second detergent storage unit (432) is introduced into the circulation housing (313) through the second detergent pipe (452) to the water collection housing (311).

[0167] In other words, the first detergent and the second detergent introduced into the circulation housing (313) can be mixed with water and discharged to the outside of the circulation housing (313) through the circulation port (363).

[0168] FIG. 11 is a rear perspective view showing a second embodiment of the pump unit, and FIG. 12 is a drawing showing water and detergent circulating according to the second embodiment of the pump unit.

[0169] FIGS. 11 and 12 illustrate a pump unit (300b) according to a second embodiment. Parts that overlap with the pump unit (300a) according to the first embodiment described above are omitted.

[0170] Referring to FIG. 11, in the pump unit (300b) according to the second embodiment, both the first detergent port (371) and the second detergent port (372) are provided in the circulation housing (313) or the circulation port (371).

[0171] Unlike the pump unit (300a) according to the first embodiment described above, a detergent is supplied to the housing unit (310) downstream from the water collection housing (311) based on the flow of water flowing in the housing unit (310).

[0172] That is, the detergent is provided to flow into the circulation housing (313) rather than the collection housing (311).

[0173] By doing so, the time for cleaning or replacing the filter member (390) can be extended by minimizing fouling of the filter member (393) as foreign substances or lint filtered by the filter member (393) provided in the water collection housing (311) clump together with the detergent supplied from the detergent supply unit (400).

[0174] In addition, in this case, it is preferable that the first detergent port (371) and the second detergent port (372) be provided in the circulation port (361). This is to increase the efficiency of mixing by ensuring that the first detergent flowing in from the first detergent port (371) and the second detergent flowing in from the second detergent port (372) effectively come into contact with the water discharged through the circulation port (361).

[0175] In addition, by providing a first detergent port (371) and a second detergent port (372) in the circulation port (361), the effect of vibration caused by the circulation pump (330) on the first detergent pipe (451) and the second detergent pipe (452) can be minimized.

[0176] In addition, based on the movement of fluid by the circulation pump (330), the detergent is supplied to the circulation port (363) located furthest downstream from the pump section (300b), thereby minimizing the residue of detergent inside the pump section (300b).

[0177] Referring to FIG. 12, water flowing into the water collection housing (311) flows to the tub (170) through the tub circulation pipe (213) by means of the circulation port (361). The first detergent and the second detergent are supplied to the circulation port (363) provided in the circulation housing (313) by means of the first detergent port (371) and the second detergent port (372), and can be supplied to the tub (170) together with the water.

[0178] FIG. 13 is a rear perspective view showing a third embodiment of the pump unit, and FIG. 14 is a drawing showing water and detergent circulating according to the third embodiment of the pump unit.

[0179] FIGS. 13 and 14 illustrate a pump unit (300c) according to a third embodiment. Parts that overlap with the pump unit (300a) according to the first embodiment and the pump unit (300b) according to the second embodiment described above are omitted.

[0180] Referring to FIG. 13, in the pump unit (300c) according to the third embodiment, the first detergent port (371) and the second detergent port (372) are both provided in the water collection housing (311) or the water collection port (371).

[0181] Unlike the pump unit (300a) according to the first embodiment and the pump unit (300b) according to the second embodiment described above, the detergent is supplied upstream of the circulation pump (350) based on the flow of water flowing in the housing unit (310) by the circulation pump (330). That is, it is configured so that all the detergent is supplied to the water collection housing (311).

[0182] Through this, the surface area and time of contact between the first detergent and the second detergent with water can be increased. As the surface area and time of contact with water are increased, the first detergent and the second detergent can be mixed more effectively with water. That is, the first detergent pot (371) and the second detergent pot (372) are provided in the water collection housing (311).

[0183] In other words, in the case of the third embodiment, water, the first detergent, and the second detergent are all provided to flow into the water collection housing (311), so that mixing of water, the first detergent, and the second detergent can occur frequently in the internal space of the water collection housing (311).

[0184] In addition, the first detergent pipe (451) and the second detergent pipe (452) are both placed in a collection housing (311) located far from the circulation pump (330) and the drainage pump (350), so that the effect of vibration during the operation of the circulation pump (300) can be minimized.

[0185] Referring to FIG. 14, water flowing into the water collection housing (311) flows into the tub (170) through the tub circulation pipe (213) via the circulation port (361). The first detergent and the second detergent flow into the water collection housing (311) via the first detergent port (371) and the second detergent port (372), and while mixed inside the water collection housing (311), they flow into the circulation housing (313) together with the water and can be supplied to the tub (170).

[0186] Meanwhile, although the above description exemplifies a case where the first and second detergents are discharged in a single step so that the supply times overlap, if the pump unit (300a, 300b, 300c) according to the first to third embodiments described above is provided in a structure such as the above, it should be interpreted as belonging to the present invention, and as shown in FIG. 4, a case where the first and second detergents are supplied in different steps so that the supply times do not overlap should also be understood as belonging to the present invention.
