Description

[Technical Field]

The present disclosure relates to a laundry treating apparatus, more specifically, to a laundry treating apparatus that may perform a refreshing cycle such as sterilization, wrinkle removal, deodorization, and drying of laundry.

[Background]

In general, a laundry treating apparatus is a home appliance that removes foreign substances from laundry using water and detergent, and includes a tub that stores water therein, a water supplier that supplies water to the tub, and a detergent supplier that is disposed on a flow channel connecting the water supplier with the tub and supplies detergent together with water to the tub.
In an existing laundry treating apparatus, the detergent supplier is in communication with the water supplier, so that when water is supplied to the tub, the detergent stored in the detergent supplier and water are supplied to the tub together.
Although such an existing laundry treating apparatus is able to guarantee a user autonomy to select a type and an amount of detergent required, there is a fundamental problem in that it is difficult to expect an appropriate amount of detergent required to be injected.
In addition, such a laundry treating apparatus also has an inconvenience of having to inject new detergent every time laundry washing is performed because all the detergent stored in the detergent supplier is injected into the tub when the detergent supplier receives water.
In addition, such a laundry treating apparatus has a problem in that the laundry is damaged as non-completely mixed highly concentrated detergent comes into direct contact with the laundry.
To overcome such a problem, a laundry treating apparatus in which the detergent supplier is controlled by a controller disposed in the laundry treating apparatus to supply the appropriate amount of detergent has emerged (See Korean Patent Application Publication No. 2008-0089086 ).
The existing laundry treating apparatus is designed such that the detergent is supplied to a liquid detergent mixing portion disposed in a bellows that allows the tub and a circulation mechanism to be in communication with each other, so that the detergent supplied to the bellows and water discharged from the tub are supplied back to the tub via the circulation mechanism, thereby indirectly injecting the detergent into the tub.
However, because the existing laundry treating apparatus has the liquid detergent mixing portion in a pipe through which water stored in the tub is discharged and is designed to supply the liquid detergent to the liquid detergent mixing portion, there is a problem that vibration of the tub is directly transmitted to the liquid detergent mixing portion, making the supply of the liquid detergent vulnerable to the vibration.
In addition, there is a laundry treating apparatus that supplies first detergent and second detergent to the tub by connecting a first detergent supply pipe that supplies the first detergent and a second detergent supply pipe that supplies the second detergent to a first connection pipe through which water of the tub is discharged and supplying the detergents, respectively (See Korean Patent Application Publication No. 2021-0060386 ).
Because the existing laundry treating apparatus has both the first detergent and the second detergent in the first connection pipe, there is a problem that the first detergent connection pipe and the second detergent connection pipe are vulnerable to the vibration occurred in the tub. In addition, because both the first and second detergents are supplied to the first connection pipe through which water is quickly discharged, there is a problem in which the detergents may remain in the first connection pipe because they are not sufficiently mixed with water.

[Summary]

[Technical Problem]

The present application aims to provide a structure in which an influence of vibrations occurring in a tub on a detergent supplier that supplies detergent in a laundry treating apparatus may be minimized.
The present application aims to provide a structure in which a detergent pipe is connected to a housing spaced apart from a tub and minimizes an influence of vibration occurring in the tub on the detergent pipe, thereby preventing detergent from leaking because of coupling release or rupture of the detergent pipe.
The present application aims to provide a structure in which a piping structure may be simplified and detergent may be efficiently supplied by reducing a length of a detergent pipe that allows a detergent supplier and a housing to be in communication with each other.
The present application aims to provide a port structure in which water and detergent may be effectively mixed with each other inside a housing.

A singular expression used in the present document includes a plural expression unless the context clearly indicates otherwise.
Hereinafter, preferred embodiments of a laundry treating apparatus and a method for controlling the same will be described in detail with reference to the attached drawings.
FIG. 1 is a perspective view showing an outer appearance of a laundry treating apparatus according to an embodiment of the present disclosure.
As illustrated in FIG. 1, a laundry treating apparatus 1 according to an embodiment of the present disclosure includes a cabinet 100 that forms the outer appearance of the apparatus and includes a front panel 110 forming a front surface.
The front panel 110 may be a surface of the cabinet 100 that is visible when the laundry treating apparatus 1 is viewed from the front (in an X-axis direction). A control panel (not shown) may be disposed on the front panel 110, so that a user may easily control laundry treatment of the laundry treating apparatus 1.
The front panel 110 may include a door panel 120 having an inlet 125 (see FIG. 2) at a front side thereof and a supply panel 140 disposed under the door panel 120. In addition, the front panel 110 has a door 130 that is capable of opening and closing the inlet 125.
The door panel 120 includes the inlet 125, so that laundry is able to be put into the cabinet 100. The door panel may include the control panel (not shown) for inputting a command that may control the laundry treatment of the laundry treating apparatus 1. Because the control panel is disposed at the front side of the cabinet 100 where the inlet is defined, the user may easily manipulate both the input of the laundry and the treatment of the laundry to perform the laundry treatment, thereby increasing convenience.
The supply panel 140 may be located under the door panel 120. The door panel 120 may be equipped with an apparatus that is used relatively infrequently by the user. For example, the door panel 120 may be equipped with a detergent supplier, a lint filter, and the like, which are necessary for maintenance and repair of the laundry treating apparatus 1.
That is, the door panel 120 may be equipped with the apparatus that is used frequently by the user, and the supply panel 140 may be equipped with the apparatus that is used relatively infrequently by the user.
The supply panel 140 may have a through-hole (not shown), so that at least a portion of a detergent drawer 415 of a detergent supplier 400 (see FIG. 2) or a filter assembly 390 of a pump assembly 300 (see FIG. 2) is exposed to the outside of the supply panel 140.
The supply panel 140 may include a supply cover 145 that covers the supply panel to protect and cover the detergent drawer 415 or the filter assembly 390 exposed to the outside.
The supply panel 140 may be recessed rearward (in a -X-axis direction) of the door panel 120, and the supply cover 145 may be constructed to cover the supply panel 140 by an amount of the recession. In this case, when the supply cover 145 covers the supply cover, a front surface of the supply cover 145 is constructed such that a step difference with a front surface of the door panel 120 is minimized, so that overall sense of unity and aesthetics of the front panel 110 may be improved.
FIG. 2 is a perspective view showing interior of a laundry treating apparatus according to an embodiment of the present disclosure.
As illustrated in FIG. 2, the laundry treating apparatus 1 according to an embodiment of the present disclosure may include a drum 150 rotatably disposed inside the cabinet 100, a tub 170 that accommodates the drum therein and stores water therein, the pump assembly 300 that is in communication with the tub and into which water discharged from the tub is introduced, and the detergent supplier 400 that supplies detergent to the tub or the pump assembly.
The drum 150 may be rotatable inside the tub 170 by a driver 155. The drum 150 may be opened such that a front side thereof is in communication with the inlet 125, and thus may accommodate therein the laundry input via the inlet 125. The drum 150 may be rotated by the driver 155 to perform the laundry treatment.
The drum 150 includes a drum hole 151. The drum 150 may allow external water to be introduced thereinto via the drum hole 151 such that water and the laundry are mixed together, and may discharge internal water into the tub 170 via the drum hole 151.
The driver 155 may be constructed such that one side thereof is coupled to a rear surface of the cabinet and the other side thereof extends through a rear surface of the tub 170 and is connected to a rear surface of the drum 150, thereby rotating the drum.
The tub 170 may have an open front side, so that the drum 150 may be accommodated inside and water supplied from the outside may be stored. The opening at the front side of the tub 170 and the inlet 125 at the front side of the drum may both be in communication with the inlet 125, and a gasket (not shown) may be disposed to prevent water from leaking.
The tub 170 may be supported inside the cabinet 100 by a support 175. The support 175 may not only support the tub 170 inside the cabinet, but may also include a buffer apparatus to offset the vibration of the tub caused by rotation of the driver.
The pump assembly 300 may be in communication with the tub 170, so that water discharged from the tub may be introduced thereinto, and the introduced water may be supplied back to the tub 170 or discharged to the outside of the cabinet 100.
The pump assembly 300 may be constructed such that water discharged from the tub 170 and the detergent supplied from the detergent supplier 400 may be introduced thereinto and mixed together. The pump assembly 300 may re-supply detergent liquid in which water and the detergent are mixed together to the tub 170.
More specifically, the pump assembly 300 may include a housing 310 (see FIG. 6) into which water discharged from the tub 170 is introduced and forming at least a portion of an outer appearance of the pump assembly 300, a circulation pump 330 (see FIG. 6) that is disposed in the housing 310 and allows water introduced into the housing 310 to flow and be re-supplied to the tub 170, and a drainage pump 350 (see FIG. 6) that discharges water introduced into the housing 310 to the outside.
The pump assembly 300 may include the filter assembly 390 to filter out foreign substances or lint remaining in water introduced from the tub. The filter assembly 390 may be constructed such that at least a portion thereof is exposed from the supply panel 140 and is extendable in a front and rear direction from the pump assembly 300, so that the user may easily remove the foreign substances, the lint, and the like captured in the filter assembly 390 by extending the filter assembly 390 without disassembling the cabinet 100.
The pump assembly 300 may be in communication with the tub via a tub drainage pipe 211 and a tub circulation pipe 213, and water may be discharged to the outside of the cabinet 100 via a pump drainage pipe 215.
The tub drainage pipe 211 may allow the tub and the pump assembly 300 to be in communication with each other such that water discharged from the tub 170 flows to the pump assembly 300.
The tub circulation pipe 213 may allow the pump assembly 300 and the tub 170 to be in communication with each other such that water supplied from the pump assembly 300 flows to the tub 170 by the circulation pump 330 (see FIG. 3).
The pump drainage pipe 215 may allow the pump assembly 300 and the outside to be in communication with each other such that water introduced into the pump assembly 300 may be discharged to the outside of the cabinet 100 via the drainage pump 350 (see FIG. 3).
The detergent supplier 400 may include a detergent casing 410 coupled to the supply panel 140 from the rear and having an open front side, and the detergent drawer 415 that is extendable in the front and rear direction from the open front side of the detergent casing 410. A detergent storage 430 (see FIG. 3) may be disposed in the detergent drawer 415.
The detergent supplier 400 may include a detergent pump 440 (see FIG. 6) that allows the detergent stored in the detergent storage 430 to flow to the outside of the detergent storage 430.
The detergent supplier 400 may supply the detergent stored in the detergent storage 430 to the tub 170 or the pump assembly 300. The detergent supplier 400 of the present disclosure may be equipped with the detergent pump 440 (see FIG. 3) to supply the detergent stored in the detergent storage 430 to the tub 170 or the pump assembly 300, and preferably, the detergent supplier 400 may be equipped to supply the detergent to the pump assembly 300 for purposes of piping simplification and coupling stabilization of a detergent pipe 450 (see FIG. 3).
In addition, a detergent pipe 450 (see FIG. 6) that allows the detergent supplier 400 and the pump assembly 300 to be in communication with each other, and allows the detergent discharged by the detergent pump 440 to flow to the pump assembly 300 may be further included.
More specifically, the detergent pipe 450 may connect the detergent supplier 400 to at least one of the tub 170, the tub drainage pipe 211, the tub circulation pipe 213, and the pump assembly 300, so that the detergent stored in the detergent supplier 400 may be directly supplied to the at least one.
In this regard, when the detergent pipe 450 is connected to the tub 170, or the tub drainage pipe 211 or the tub circulation pipe 213, the vibration occurred in the tub 170 during the laundry treatment process may be directly transmitted to the detergent pipe 450. In this case, a coupling strength of the detergent pipe 450 may be reduced, or a sealing portion may be ruptured, causing the detergent inside to leak out. Alternatively, because of the vibration applied to the detergent pipe 450, there is a concern that bubbles may be generated in the detergent flowing through the detergent pipe 450, thereby reducing reliability of the detergent supply.
The detergent pipe 450 of the present disclosure may allow the detergent supplier 400 to be in communication with the pump assembly 300, preferably the housing 310, thereby minimizing the transmission of the vibration occurred in the tub 170 to the detergent pipe 450.
Specifically, the vibration occurred in the tub 170 may be primarily attenuated by the support 175, and secondarily attenuated by a bellows that may be formed in the tub drainage pipe 211 or the tub circulation pipe 213, so that the vibration may be applied to the pump assembly 300 to a minimum. In addition, the pump assembly 300 may be coupled to a base 190 (see FIG. 6) disposed on a bottom surface of the cabinet 100, and the vibration may be attenuated thirdly by the base 190.
That is, by connecting the detergent pipe 450 to the pump assembly 300, where the vibration of the tub is attenuated to the maximum, and supplying the detergent, the reliability of the detergent supply of the detergent supplier 400 by the detergent pipe 450 may be improved.
In one example, the detergent storage 410 may include a first detergent storage 411 (see FIG. 10) storing first detergent, and a second detergent storage 412 (see FIG. 10) storing second detergent.
In this regard, one of the first detergent and the second detergent may be a laundry detergent used in a laundry washing cycle of the laundry treating apparatus, and the other may be a softener used in a rinsing cycle of the laundry treating apparatus. However, the first detergent and the second detergent of the present disclosure may not be limited thereto, and may be laundry detergents or softeners having the same chemical composition as each other.
The detergent pump 440 may include a first detergent pump 441 (see FIG. 6) that is disposed in the first detergent storage 411 and discharges the first detergent and a second detergent pump 442 (see FIG. 6) that is disposed in the second detergent storage 442 and discharges the second detergent.
The detergent pipe 450 may include a first detergent pipe 451 (see FIG. 6) that is in communication with the first detergent pump 441 and supplies the first detergent therethrough and a second detergent pipe 452 (see FIG. 6) that is in communication with the second detergent pump 442 and supplies the second detergent therethrough.
The first detergent pipe 451 and the second detergent pipe 452 may allow the detergent storage 410 and the pump assembly 300 to be in communication with each other, thereby supplying the first detergent and the second detergent to the pump assembly 300, respectively.
It should be understood that the laundry treating apparatus 1 of the present disclosure is not limited in the type of detergent to be injected or the number of detergent pipes 450.
That is, the detergent pipe of the present disclosure may be equipped with not only the first detergent pipe 451 and the second detergent pipe 452, but also a plurality of detergent pipes 450, or may also be equipped with one detergent pipe 450.
In addition, the detergent supplier 400 of the present disclosure is located below the tub 170, but is not limited thereto, and is able to be located above the tub 170.
The detergent supplier 400 of the present disclosure is exemplified as an automatic detergent supplier that automatically supplies the appropriate amount of detergent at an appropriate time by a controller, but is not necessarily limited thereto and is able to be a manual detergent supplier that supplies the detergent to the tub 170 together with water supplied from an external source. In addition, the present disclosure may be a laundry treating apparatus equipped with both the automatic detergent supplier and teh manual detergent supplier.
The detergent supply and water circulation of the detergent supplier 400 will be described later.
FIG. 3 is a diagram showing a movement of water and detergent in a laundry treating apparatus of the present disclosure.
Referring to FIG. 3, water discharged from the tub 170 is introduced into the housing 310 of the pump assembly 300 via the tub drainage pipe 211. Water introduced into the housing 310 may be re-supplied to the tub 170 via the tub circulation pipe 213 by the circulation pump 330. That is, the tub drainage pipe 213, the housing 310, and the circulation pipe may be defined as a "circulation flow channel" through which water inside the tub 170 circulates.
In addition, water introduced into the housing 310 may be discharged to the outside of the cabinet via the pump drainage pipe 215 by the drainage pump 450. That is, the tub drainage pipe 211, the housing 310, and the pump drainage pipe 215 may be defined as a "drainage flow channel" through which water inside the tub 170 is discharged to the outside.
To improve reliability of the water circulation by the circulation flow channel and the drainage flow channel, the circulation pump 330 and the drainage pump 350 may be controlled by the controller (not shown), so that when one pump operates, the other one may stop operating.
In addition, the detergent stored in the detergent storage 430 of the detergent supplier 400 may be discharged to the outside of the detergent storage 430 by the detergent pump 440 and supplied to the pump assembly 300, preferably the housing 310, via the detergent pipe 450. That is, the detergent supplier 400, the detergent pipe 450, the housing 310, and the tub circulation pipe 213 may be defined as a "detergent supply flow channel". That is, the detergent supplier 400 may supply the detergent to the tub 170 via the detergent supply flow channel.
In one example, as described above, the housing 310 may define a space in which water introduced from the tub drainage pipe 213 and the detergent introduced from the detergent pipe 450 are introduced and mixed together. Water and the detergent are mixed together in the housing 310 to form a laundry solution, and then the laundry solution is supplied to the tub 170 via the tub circulation pipe 213, so that the detergent may be supplied to the tub 170 at a more uniform concentration, compared to when the detergent is directly supplied to the tub 170.
In other words, when the detergent is directly supplied to the tub 170, the detergent that has not been completely mixed with water comes into contact with the laundry inside the drum 150, so that the laundry may be damaged depending on a material of the laundry, and the laundry may capture the detergent, causing the concentration of the detergent inside the tub to become uneven.
Accordingly, the present disclosure may increase efficiency of the laundry treatment by supplying water and the detergent together to the housing 310 of the pump assembly 300, mixing them, and then supplying them to the tub 170.
FIG. 4 is a block diagram showing laundry treatment performed according to an embodiment of the present disclosure.
Referring to FIG. 4, the laundry treatment of the laundry treating apparatus 1 according to an embodiment of the present disclosure may include sensing an amount of laundry loaded into the drum 150 (S10), supplying the detergent (S20), performing the laundry washing cycle during the laundry treatment by rotating the driver 155 based on a set algorithm (S30), primarily rinsing the laundry accommodated in the drum 150 (S40), supplying the softener via the detergent supplier 400, secondarily rinsing the laundry accommodated in the drum 150 (S60), and draining water accommodated inside the tub 170 and dehydrating the laundry (S70).
Although not shown in the drawing, steps before and after the laundry washing cycle (S30), primary rinsing (S40), and secondary rinsing (S60) steps may include supplying water to the tub 170 and discharging water from the tub.
The laundry amount sensing step (S10) may measure the amount (a weight) of the laundry accommodated in the drum 150 by a difference in current values sensed by rotating the driver 155. Values of a first detergent amount and a second detergent amount, which will be described later, may be determined in advance based on the measured laundry amount.
The laundry detergent supply step (S20) is a step of supplying the detergent used in the laundry washing cycle (S30). The laundry detergent supply step (S20) may include operating the circulation pump 330 (S21), determining a supply amount of the first detergent based on the measured laundry amount value by the controller (not shown) (S23), and operating the first detergent pump 441 to supply the first detergent to the housing 310 (S25).
Here, an order in which the first detergent and the second detergent are injected is irrelevant. That is, the laundry detergent supply step (S20) may be a step of operating the second detergent pump 442 and supplying the second detergent, unlike the drawing.
In addition, the circulation pump operating step (S21) and the detergent amount determination step (S23) may be performed in a reverse order. That is, as long as the first detergent injection step (S25) is the last step of the laundry detergent supply step (S20), it shall be considered within the scope of the present disclosure.
In the primary rinsing step (S40), the detergent may not be supplied, but external water may be supplied, so that the driver 155 may be rotated by the controller based on a set algorithm.
The softener supply step (S50) may include operating the circulation pump (S51), determining a detergent amount of the second detergent set in advance based on the laundry amount value measured in the laundry amount sensing step (S10) (S53), and supplying the second detergent by the second detergent pump 442 based on the set detergent amount.
In the softener supply step (S50), the first detergent may be supplied or detergent the same as the first detergent may be supplied. Furthermore, as long as the softener supply step (S50) involves the supply of the second detergent, an order of the circulation pump operating step (S51) and the detergent amount determination step (S53) may be changed.
As described above, times at which the first detergent and the second detergent are supplied by the detergent supplier 400 may be different from each other. Alternatively, the first detergent and the second detergent may be supplied at the same time in the laundry detergent supply step (S20) and the softener supply step (S50).
FIG. 5 is a rear view of the detergent supplier 400 and the pump assembly 300 at a lower portion of the cabinet 100 in an embodiment of the present disclosure.
Referring to FIG. 5, the cabinet 100 may include the base 190 that is disposed at the lower portion thereof and provides a space in which various equipment may be installed.
The detergent supplier 400 and the pump assembly 300 may be coupled to the base 190. The detergent supplier 400 and the pump assembly 300 may be disposed at the rear (in the -X-axis direction) of the supply panel 140, and may be at least partially exposed to the outside when the supply cover 145 is opened.
In addition, the detergent supplier 400 and the pump assembly 300 may be in communication with each other via the detergent pipe 450. The detergent supplier 400 and the pump assembly 300 may be disposed adjacent to each other to reduce an extension length of the detergent pipe 450 and simplify a piping structure.
Specifically, the detergent supplier 400 may be disposed adjacent to a first panel among panels forming both side surfaces (in the Y-axis) of the cabinet 100, and the pump assembly 300 may be disposed adjacent to a second panel facing the first panel among the panels forming both side surfaces of the cabinet 100, so that they may be arranged in parallel with each other in a width direction of the cabinet.
The housing 310 of the pump assembly 300 may be disposed below the tub 170, and may be in communication with the tub drainage pipe 213, the tub circulation pipe 213, the pump drainage pipe 215, and the detergent pipe 450.
In other words, to simplify a piping relationship of pipes connected to the housing 310 of the pump assembly, the detergent supplier 400 and the pump assembly 300 may be arranged in parallel with each other in the width direction at a location below the tub 170.
With such a structure, not only the transmission of the vibration occurred in the tub to the detergent pipe 450 may be minimized, but also the piping structure may be simplified.
In one example, the first detergent pipe 451 and the second detergent pipe 452 of the detergent pipe 450 may be connected to different locations on the housing 310.
A connection relationship between the detergent pipe 450 and the housing 310 will be described later.
Hereinafter, the pump assembly 300 according to first to third embodiments will be described, but this is only for a purpose of describing in detail a connection relationship between the pump assembly 300 and the detergent pipe 450, and it should be understood that the present disclosure is not limited to respective embodiments to be described later.
FIG. 6 is a rear perspective view of a pump assembly 300a according to a first embodiment.
Referring to FIG. 6, the pump assembly 300a according to the first embodiment may include the housing 310 to which the tub pipes 211 and 213, the pump drainage pipe 215, and the detergent pipe 450 are connected and defining a space in which a fluid flows therein, the circulation pump 330 that is disposed on the housing 310 and re-supplies water introduced into the housing 310 to the tub 170, the drainage pump 350 that is disposed on the housing 310 and discharges water introduced into the housing 310 to the outside, and the filter assembly 390 (see FIG. 8) that is disposed inside the housing 310 and filters the foreign substances or the lint.
In one example, the housing 310 may include a water collecting housing 311 into which water discharged from the tub 170 is introduced and to which the tub drainage pipe 211 is connected, a circulation housing 313 that is in communication with the water collecting housing 311 and provides a space where the circulation pump 330 is coupled, and a drainage housing 315 that is in communication with the water collecting housing 311 and provides a space where the drainage pump 350 is coupled.
In addition, the housing 310 may include housing ports 361, 363, and 365 that provide spaces where the tub pipes 211 and 213 and the pump drainage pipe 215 are connected, and detergent ports 371 and 372 connected to the detergent pipe 450 and into which the detergent is introduced.
The housing ports 361, 363, and 365 may protrude to the outside of the housing. The housing ports 361, 363, and 365 may include a water collecting port 361 that is disposed on the water collecting housing 311, is connected to the tub drainage pipe 211, and receives water stored in the tub, a circulation port 363 disposed on the circulation housing 313 and through which water or the detergent introduced into the circulation housing 313 by the circulation pump 330 is discharged to the tub circulation pipe 213, and a drainage port 365 disposed on the drainage housing 315 and through which water introduced into the drainage housing 315 by the drainage pump 350 is discharged to the pump drainage pipe 215.
As shown in the drawing, the water collecting port 361 may extend rearward of the housing 310. Accordingly, water introduced into the tub drainage pipe 211 may hit a front side of the water collecting housing 311 once and form an irregular waterflow inside, thereby improving efficiency of mixing with the detergent introduced by the detergent pipe.
In addition, the water collecting port 361 and the drainage port 365 may be disposed in parallel with each other for the piping simplification. Preferably, the water collecting port 361 and the drainage port 365 may be formed by extending rearward of the housing 310.
The circulation port 363 may be disposed so as not to face the water collecting port 361 and a circulation hole 3113 (see FIG. 9) of the water collecting housing 311.
In other words, because a flow angle of the fluid changes while water introduced into the water collecting housing 311 by the water collecting port 361 passes through the circulation housing 313 and the circulation port 363, mixing efficiency of water and the detergent may be improved accordingly.
Preferably, the water collecting port 361 may be disposed to extend rearward from the water collecting housing 311, the circulation housing 311 may be disposed to extend laterally from the water collecting housing 311, and the circulation port 363 may be disposed to extend upward from the water collecting housing 311.
The detergent ports 371 and 372 may be formed to protrude outward from the housing 310. The detergent ports 371 and 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.
In the pump assembly 300a according to the first embodiment, the first detergent pipe 451 is connected to the water collecting housing 311, and the second detergent pipe 452 is disposed on the circulation housing 313 so as to be disposed downstream of the circulation pump 330.
The first detergent port 371 may extend not parallel to the water collecting port 361, preferably perpendicular thereto, and the second detergent port 372 may extend so as not to face the circulation port 363 and the circulation hole 3113, preferably perpendicular thereto.
In addition, the first detergent port 371 may be disposed to extend upward from the water collecting port 361 or the water collecting housing 311, and the second detergent port 372 may extend rearward from the circulation port 363 or the circulation housing 313.
FIG. 7 is a cross-sectional view taken along a line 1-1' in FIG. 6, FIG. 8 is a cross-sectional view taken along a line 2-2' in FIG. 6, and FIG. 9 is a cross-sectional view taken along a line 3-3' in FIG. 6. Referring to FIGS. 7 to 9, the pump assembly 300a according to the first embodiment will be described.
FIG. 7 is a cross-sectional view of the circulation housing 313. As described above, the circulation housing 313 may provide a space in which the circulation pump 330 is disposed such that water introduced into the water collecting housing 311 is discharged.
That is, at least a portion of the circulation pump 330, preferably a circulation impeller 3331 of the circulation pump 330, may be disposed inside the circulation housing 313, so that water introduced into the circulation housing 311 may flow into the tub circulation pipe 213 via the circulation housing 313 and the circulation port 363.
The circulation housing 313 may include the circulation port 363 through which water is discharged, and the second detergent port 372 disposed in the circulation port 363 or the circulation housing 313. Water introduced via the water collecting housing 311 is introduced into the circulation housing 313 via the circulation hole 3113.
In addition, the circulation housing 313 may include the second detergent port 372, so that the second detergent may be introduced into the circulation housing 313.
Water and the detergent introduced into the circulation housing 313 may be mixed with each other in an internal space of the circulation housing 313, and may be discharged together to the tub circulation pipe 213 via the circulation port 363 by the circulation impeller 3331 and supplied to the tub 170.
The second detergent port 372 may be disposed so as not to face the circulation port 363, preferably perpendicular thereto. As the second detergent port 372 is disposed in this manner, an angle between a flow direction of water discharged to the circulation port 363 and a flow direction of the detergent introduced into the second detergent port 372 is maximized, thereby allowing water and the detergent to be mixed together better.
In addition, a detergent check valve 375 may be disposed in the second detergent pipe 452 or the second detergent port 372. The detergent check valve is designed to allow only a movement of the fluid from the detergent supplier 400 toward the pump assembly 300, and to block a movement of the fluid from the pump assembly 300 to the detergent supplier 400.
In addition, the detergent check valve 375 may be disposed 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.
In the drawing, the second detergent port 372 is disposed on the circulation housing 313 as an example, but a case in which the first detergent port 371 is disposed on the circulation housing 313 and the second detergent port 372 is disposed on the water collecting housing 311 may also be considered to belong to the pump assembly 300a of the first embodiment of the present disclosure.
FIG. 8 is a cross-sectional view of the water collecting housing 311. Referring to FIG. 8, the water collecting housing 311 may include the water collecting port 361 and the first detergent port 371, and may have a space in which the fluid may flow defined therein.
That is, water introduced from the tub drainage pipe 211 via the water collecting port 361 and the detergent introduced from the first detergent pipe 451 via the first detergent port 371 may be introduced into the water collecting housing 311.
As described above, the first detergent port 371 and the water collecting port 361 are arranged so as not to face each other, so that the flow direction of water introduced from the water collecting port 361 and the flow of the detergent introduced from the first detergent port 371 are misaligned with each other, preferably perpendicular to each other, thereby improving the mixing efficiency with water without precipitating highly concentrated detergent.
In addition, the first detergent port 371 or the first detergent pipe 451 may include the detergent check valve 375, so as to allow a movement of the fluid from the detergent supplier 400 to the water collecting housing 311 and block a movement of the fluid from the water collecting housing 311 to the detergent supplier 400.
In addition, the water collecting housing 311 may be a first space where water discharged from the tub 170 is introduced into the pump assembly 300, and the foreign substances or the lint discharged from the tub 170 may be introduced thereinto together.
Accordingly, the water collecting housing 311 of the pump assembly 300 of the present disclosure may be equipped with the filter assembly 390. The filter assembly 390 is constructed such that at least a portion thereof is disposed in the internal space of the water collecting housing 311 and is able to be extended from the water collecting housing 311.
The filter assembly 390 may include a filter handle 391 that is positioned outside the water collecting housing 311 and is exposed from the supply panel 140, a filter member 393 that extends from the filter handle 391 in a rearward direction of the water collecting housing 311 and filters the foreign substances or the lint, and a filter sealing 395 that seals a space between the filter member 393 or the filter handle 391 and the water collecting housing 311 such that water does not leak.
The user may open the supply cover 145, hold the filter handle 391 exposed through the supply panel 140, and extend the filter handle 391 forward to separate the filter assembly 390 from the water collecting housing 311.
The user may wash the separated filter assembly 390 or replace the filter assembly 390, and then push the same back rearward from the supply panel 140 to mount the filter assembly 390 in the water collecting housing 311.
FIG. 9 is a cross-sectional view of the filter assembly 300a. Referring to FIG. 9, the circulation housing 313 may be disposed on one side of the water collecting housing 311, and the drainage housing 315 may be disposed on the other side of the water collecting housing 311.
The circulation pump 330 may include a circulation pump casing 331 forming at least a portion of an outer appearance of the circulation pump, and a circulation motor assembly 333 disposed inside the circulation pump casing 331.
The circulation pump casing 331 may be constructed to accommodate at least a portion of the circulation motor assembly 333 therein, and may be coupled to the circulation housing 313. That is, the circulation housing 313 may be formed in a shape in which one side facing the water collecting housing 311 is open, and the circulation pump casing 331 may be constructed to shield the open portion.
The circulation motor assembly 333 may be at least partially accommodated in the circulation pump casing 331, and the remaining portion thereof may be accommodated in the circulation housing 313.
The circulation motor assembly 332 may include the circulation impeller 3331 that is rotatably disposed in the circulation housing 313, a circulation motor 3333 that is accommodated in the circulation pump casing 331 and generates a driving force, and a rotation shaft 3332 that connects the circulation motor 3333 with the circulation impeller 3331 and transmits the driving force of the circulation motor 3333 to the circulation impeller 3331.
The drainage pump 350 may include a drainage pump casing 351 forming at least a portion of an outer appearance of the circulation pump, and a drainage motor assembly 353 disposed inside the drainage pump casing 351.
The drainage pump casing 351 may be constructed to accommodate at least a portion of the drainage motor assembly 353 therein, and may be coupled with the drainage housing 315. That is, the drainage housing 315 may be formed in a shape in which one side facing the water collecting housing 311 is open, and the drainage pump casing 351 may shield the open portion.
The drainage motor assembly 353 may be at least partially accommodated in the drainage pump casing 351, and the remaining portion thereof may be accommodated in the drainage housing 315.
The drainage motor assembly 353 may include a drainage impeller 3531 that is rotatably disposed in the drainage housing 315, a drainage motor 3533 that is accommodated in the drainage pump casing 351 and generates a driving force, and a rotation shaft 3352 that connects the drainage motor 3533 with the drainage impeller 3531 and transmits the driving force of the drainage motor 3533 to the drainage impeller 3531 and rotates the same.
The water collecting housing 311 may be connected to each of the circulation housing 313 and the drainage housing 315. More specifically, the water collecting housing 311 may have the circulation housing 313 disposed on one side thereof, and may include the circulation hole 3113 in communication with the circulation housing 313. In addition, the water collecting housing 311 may have the drainage housing 315 on the other side thereof, and may include a drainage hole 3115 in communication with the drainage housing 315.
In other words, water introduced into the water collecting housing 311 via the tub drainage pipe 211 may move to the circulation housing 313 via the circulation hole 3113 or move to the drainage housing 315 via the drainage hole 3115.
In addition, the detergent introduced via the first detergent pipe 451 may also move to the circulation housing 313 via the circulation hole 3113.
The circulation hole 3113 allows the water collecting housing 311 and the circulation housing 313 to be in communication with each other, and preferably has a diameter smaller than a diameter of the water collecting housing 311 or the circulation housing 313.
As the circulation hole 3113 is formed with such a size, a pressure increases as water and the detergent introduced into the water collecting housing 311 pass through a narrow passage (the circulation hole 3113), and as a result, the mixing efficiency of water and the detergent may increase.
Although the present disclosure exemplifies that the housing 310, the circulation pump casing 331, and the drainage pump casing 351 are coupled with each other to form an overall outer appearance of the pump assembly 300, but the present disclosure is not limited thereto, and it should be understood that the housing 310, the circulation pump 330, and the drainage pump 350 may each be implemented in a structure in which they are separated and spaced apart from each other and are in communication with each other by separate pipes.
FIG. 10 is a diagram showing circulation of water and the detergent along the pump assembly 300a of the first embodiment.
Referring to FIG. 10, water discharged from the tub 170 is introduced into the water collecting housing 311 via the tub drainage pipe 211, and the first detergent stored in the first detergent storage 431 is also introduced into the water collecting housing 311 via the first detergent pipe 451.
Water and the first detergent introduced into the water collecting housing 311 are introduced into the circulation housing 313 by the flow generated by the circulation pump 330. In addition, in the circulation housing 313, the second detergent stored in the second detergent storage 432 is introduced into the water collecting housing 311 via the second detergent pipe 452.
In other words, the first detergent and the second detergent introduced into the circulation housing 313 may be mixed with water and discharged to the outside of the circulation housing 313 via the circulation port 363.
FIG. 11 is a rear perspective view showing a second embodiment of a pump assembly, and FIG. 12 is a diagram showing circulation of water and detergent according to a second embodiment of a pump assembly.
FIGS. 11 and 12 illustrate a pump assembly 300b according to a second embodiment. A description redundant with the description of the pump assembly 300a according to the first embodiment above will be omitted.
Referring to FIG. 11, the pump assembly 300b according to the second embodiment has both the first detergent port 371 and the second detergent port 372 on the circulation housing 313 or the circulation port 371.
Unlike in the pump assembly 300a according to the first embodiment described above, the detergent is supplied to the housing 310 from downstream of the water collecting housing 311 based on the flow of water flowing in the housing 310.
That is, the detergent is introduced into the circulation housing 313, not the water collecting housing 311.
Accordingly, the foreign substances or the lint filtered by the filter member 393 disposed in the water collecting housing 311 are clumped by the detergent supplied from the detergent supplier 400 and minimize fouling of the filter member 393, thereby extending a cleaning or replacement cycle of the filter assembly 390.
In addition, in this case, it is preferable that the first detergent port 371 and the second detergent port 372 are disposed on the circulation port 361. It is to increase the efficiency of mixing by allowing the first detergent introduced from the first detergent port 371 and the second detergent introduced from the second detergent port 372 to be effectively in contact with water discharged via the circulation port 361.
In addition, because the first detergent port 371 and the second detergent port 372 are disposed on the circulation port 361, influence of the vibration by the circulation pump 330 on the first detergent pipe 451 and the second detergent pipe 452 may be minimized.
In addition, as the detergent is supplied to the circulation port 363 located most downstream in the pump assembly 300b based on the movement of the fluid by the circulation pump 330, the detergent remaining inside the pump assembly 300b may be minimized.
Referring to FIG. 12, water introduced into the water collecting housing 311 flows into the tub 170 via the tub circulation pipe 213 by the circulation port 361. The first detergent and the second detergent may be supplied to the circulation port 363 disposed on the circulation housing 313 by the first detergent port 371 and the second detergent port 372, and may be supplied to the tub 170 together with water.
FIG. 13 is a rear perspective view showing a third embodiment of a pump assembly, and FIG. 14 is a diagram showing circulation of water and detergent according to a third embodiment of a pump assembly.
FIGS. 13 and 14 illustrate a pump assembly 300c according to a third embodiment. A description redundant with the descriptions of the pump assembly 300a according to the first embodiment and the pump assembly 300b according to the second embodiment above will be omitted.
Referring to FIG. 13, the pump assembly 300c according to the third embodiment has both the first detergent port 371 and the second detergent port 372 on the water collecting housing 311 or the water collecting port 371.
Unlike in the pump assembly 300a according to the first embodiment and the pump assembly 300b according to the second embodiment described above, the detergent is supplied from upstream of the circulation pump 350 based on the flow of water flowing in the housing 310 by the circulation pump 330. In other words, the detergent is entirely supplied to the water collecting housing 311.
Accordingly, areas and times of the first detergent and the second detergent in contact with water may be increased. By increasing the contact area with water and the contact time with water, the first detergent and the second detergent may be mixed with water more effectively. That is, the first detergent port 371 and the second detergent port 372 are disposed on the water collecting housing 311.
In other words, in a case of the third embodiment, as water, the first detergent, and the second detergent are all introduced into the water collecting housing 311, the mixing of water, the first detergent, and the second detergent may frequently occur in the internal space of the water collecting housing 311.
In addition, as the first detergent pipe 451 and the second detergent pipe 452 are both disposed on the water collecting housing 311 far from the circulation pump 330 and the drainage pump 350, the influence of the vibration during operation of the circulation pump 300 may be minimized.
Referring to FIG. 14, water introduced into the water collecting housing 311 flows into the tub 170 via the tub circulation pipe 213 by the circulation port 361. The first detergent and the second detergent may be introduced into the water collecting housing 311 by the first detergent port 371 and the second detergent port 372, may be mixed together inside the water collecting housing 311, may flow together with the water into the circulation housing 313 and be supplied to the tub 170.
The foregoing description exemplifies the case in which the first detergent and the second detergent are discharged in one cycle step such that their supply times overlap each other. However, when configured with a structure similar to the pump assemblies 300a, 300b, and 300c according to the first to third embodiments described above, it should be interpreted as falling within the scope of the present disclosure. Furthermore, as shown in FIG. 4, even cases in which the first detergent and the second detergent are supplied in different cycle steps such that their supply times do not overlap each other should be understood as falling within the scope of the present disclosure.
Although the present disclosure has been illustrated and described with respect to the specific embodiments, it will be obvious to those skilled in the art that the present disclosure may be variously improved and changed without departing from the technical idea of the present disclosure provided by the following patent claims.
