It may be combined or combined with the storage unit 300 in the rear of the deformation space (359).

The front end of the elastic bar 350 to which the pressing part 352 is pressed may be located in the deformable space 359 . The elastic bar 350 may be elastically deformed so that the front end is moved downward when the pressing part 352 is pressed, and in this case, the engaging part 353 protruding upward from the elastic bar 350 is also moved downward. Accordingly, the locking portion 353 and the stopper 250 do not overlap with each other in the front-rear direction X, so that the user can completely withdraw the storage unit 300 .

The elastic bar 350 may be elastically deformed as a whole, or the rear end or any part may be elastically deformed and the front end may be moved downward so that the front end is located in the deformation space 359 .

On the other hand, referring to FIG. 27 , in an embodiment of the present invention, the elastic bar 350 includes an upper extension part 358 extending upwardly from the coupling point with the storage unit 300 at the rear end thereof, The front end portion may extend forward from the upper extension portion 358 to form a free end.

Specifically, the elastic bar 350 may be positioned spaced apart upward from the bottom surface of the storage unit 300, that is, the storage frame 390 through the upper extension portion 358, and thus the front end portion of the storage frame 390. It is possible to form a free end spaced apart from the bottom surface of the

In addition, in an embodiment of the present invention, the elastic bar 350 may include a bending portion 356 that is positioned at the rear of the locking portion 353 and is bent in the vertical direction (Z).

That is, in one embodiment of the present invention, while the front end of the elastic bar 350 maintains its shape with rigidity, when the pressing part 352 is pressed, the bending part 356 causes deformation of the elastic bar 350 . The front end may be positionally moved downward.

Unlike the front or rear end of the elastic bar 350 , the bending portion 356 may be made of a material having high elasticity, or may be integrally molded as a whole and formed in a curved shape.

Referring back to FIG. 19 , in an embodiment of the present invention, the locking part 353 is located behind the auxiliary detergent accommodating part 340 , so that the storage unit 300 is withdrawn and the locking part 353 . In a state in which is in contact with the stopper 250 , the auxiliary detergent accommodating part 340 may be exposed to the outside of the opening 15 .

As described above, since the position of the locking part 353 may correspond to the set withdrawal distance for the storage unit 300, even if the user withdraws the storage unit 300 by the set withdrawal distance, the use of the storage unit 300 is For ease, the auxiliary detergent accommodating part 340 may be located more forward than the catching part 353 .

Accordingly, the user inserts the detergent through the detergent input hole 312 located in the front of the detergent storage container 310 in a state in which the storage unit 300 is withdrawn by the set withdrawal distance, or at the rear of the detergent input unit 313 . It is possible to put the auxiliary detergent in the auxiliary detergent receiving unit 340 is located.

Meanwhile, in an embodiment of the present invention, the dispenser unit 200 may further include a guide protrusion 255 . 26 shows an enlarged view of the guide protrusion 255 as viewed from below, and FIGS. 27 and 28 show the guide protrusion 255 penetrating through the through groove 354 .

26 to 28 , the guide protrusion 255 extends rearward from the rear surface of the stopper 250 and may have a narrower width than the stopper 250 . The locking part 353 may have a through groove 354 formed in the center based on the width direction Y, and the guide protrusion 255 is the storage unit 300 with which the locking part 353 is drawn out. may pass through the through hole 354 while in contact with the stopper 250 .

Meanwhile, FIG. 30 shows a state in which the front end of the elastic bar 350 is caught by the stopper 250 in a state in which the guide protrusion 255 is removed. In the process of withdrawing the storage unit 300 , the front end of the elastic bar 350 protruding forward to form a free end may be unintentionally caught by the stopper 250 depending on the use environment.

In this case, the user cannot withdraw the storage unit 300 as much as the set withdrawal distance, and the detergent storage container 310 or the auxiliary detergent accommodating part 340 is not exposed to the outside of the opening 15, which makes it difficult for the user to use it. can occur.

In one embodiment of the present invention, the guide protrusion 255 and the through groove 354 are provided to prevent the front end of the elastic bar 350 from contacting the stopper 250 to prevent the storage unit 300 from being pulled out. can

The guide protrusion 255 may have a narrower width than the stopper 250 , and the through-groove 354 may have a width corresponding to the guide protrusion 255 . The engaging portion 353 may have a wider width than the through groove 354 .

The guide protrusion 255 extends backward from the rear surface of the stopper 250 . Accordingly, a situation in which the elastic bar 350 is unintentionally positioned so that the front end overlaps the stopper 250 can be prevented.

For example, in the process of withdrawing the adjustment unit, the front end of the elastic bar 350 may have a height limited by the guide protrusion 255 before reaching the stopper 250, and thus the elastic bar reaching the stopper 250 ( The front end of the 350 is positioned at a lower height than the stopper 250 by the guide protrusion 255 so as not to contact the stopper 250 .

On the other hand, the locking part 353 has a through-groove 354 formed in the center, and moves forward in a state where the through-groove 354 is penetrated by the guide protrusion 255 , so movement is limited by the guide protrusion 255 . this will not occur.

When the stopping part 353 reaches the stopper 250, the stopping part 353 having a width wider than the through groove 354 overlaps with the stopper 250 having a width wider than the guide protrusion 255 and comes into contact. , thus, at the set withdrawal distance, the locking part 353 is completely in contact with the stopper 250 and can limit the withdrawal of the storage unit 300 .

On the other hand, in an embodiment of the present invention, the guide protrusion 255 may have a lower surface inclined as the protrusion height from the fixing unit is gradually decreased as the guide protrusion 255 is further away from the stopper 250 .

26 shows the guide protrusion 255 having an inclined lower surface as viewed from below, and FIG. 27 shows the guide protrusion 255 having an inclined lower surface passing through the through groove 354. .

As the guide protrusion 255 is inclined toward the rear, the protruding length or height is reduced, so that the front end of the elastic bar 350 is unintentionally caught by the guide protrusion 255 and the movement is restricted effectively. Since the front end of the elastic bar 350 is naturally induced to have a lower height than the stopper 250 along the inclined lower surface, an unintentional overlapping situation of the elastic bar 350 can be effectively prevented. .

On the other hand, FIG. 31 shows the detergent reservoir 310 as viewed from the top, FIG. 32 shows the vent hole 360 of the detergent reservoir 310 as viewed from the top, and FIG. 33 shows the vent hole ( 360) is shown in cross-section in the vertical direction (Z).

31 to 33 , in one embodiment of the present invention, a vent hole 360 may be formed in the detergent storage container 310 in which detergent is stored and inserted into the opening 15 in the front-rear direction (X).

Specifically, the detergent storage container 310 may have a storage space for storing detergent therein, and a ventilation hole 360 may be formed on the upper surface to communicate the storage space with the outside. For example, a storage space may be formed in the case 339 of the detergent storage container 310 , and a ventilation hole 360 may be formed in the cap member 330 of the detergent storage container 310 .

The vent hole 360 has a central part 362 between the lower end 361 facing the storage space and the upper end 363 facing the outside of the detergent reservoir 310 is parallel to the upper surface of the detergent reservoir 310 . can be extended

The lower end 361 of the ventilation hole 360 is opened to the storage space, and the upper end 363 of the ventilation hole 360 is opened to the outside of the detergent storage container 310 . The ventilation hole 360 may have a form in which the central axes of the upper end 363 and the lower end 361 are spaced apart from each other so that the central portion 362 extends in parallel with the upper surface of the detergent storage container 310 .

That is, as shown in FIG. 33 , the ventilation hole 360 may have a shape in which a center line extending in a cross-section is bent. Accordingly, a situation in which the detergent inside the detergent storage container 310 leaks to the outside can be effectively suppressed.

Specifically, the detergent storage container 310 is moved forward and backward along the opening 15 by the user, and in this process, the detergent inside the detergent storage container 310 may leak to the outside through the ventilation hole 360 . .

In an embodiment of the present invention, the ventilation hole 360 forms a central portion 362 extending in parallel with the upper surface of the detergent storage container 310 between the upper end 363 and the lower end 361 extending in the vertical direction (Z). By doing so, the area in which the storage space and the outside of the detergent storage container 310 directly communicate in the vertical direction (Z) is minimized, and thus the detergent leaking through the vent hole 360 to the outside of the detergent storage container 310 is minimized. be able to

On the other hand, as shown in FIG. 33 , in an embodiment of the present invention, the upper end 363 and the lower end 361 of the vent hole 360 extend in the vertical direction (Z) of the detergent reservoir 310 and It may be connected to both ends of the central part 362, respectively.

Therefore, the movement path of the detergent to leak from the storage space of the detergent storage container 310 to the outside is bent several times, and leakage of the detergent can be minimized.

In addition, in an embodiment of the present invention, the central portion 362 of the ventilation hole 360 may extend in a direction transverse to the front-rear direction (X), for example, in the lateral direction (Y) of the detergent storage container (310). .

Detergent flowing by the movement of the detergent storage bin 310 may have momentum in the front-back direction (X) like the detergent storage bin 310, and therefore, an embodiment of the present invention provides a detergent that moves in the front-rear direction (X). In order to minimize the situation in which leaking out through the upper end 363 while moving the central portion of the vent hole 360, the central portion 362 is moved in a direction transverse to the front-rear direction (X), for example, in the lateral direction (Y). They can be extended to reduce detergent leakage.

Meanwhile, FIG. 32 shows an overlapping region 369 in which the upper end 363 and the lower end 361 of the ventilation hole 360 overlap in the vertical direction (Z). Referring to FIG. 32 , in an embodiment of the present invention, in the ventilation hole 360 , the upper end 363 and the lower end 361 overlap in the vertical direction Z to expose the storage space to the outside. An overlapping region 369 may be formed.

A method of manufacturing the cap member 330 of the detergent storage container 310 having the ventilation hole 360 or the ventilation hole 360 may be varied. For example, an injection molding method using an upper mold corresponding to the upper end 363 of the vent hole 360 and a lower mold corresponding to the lower end 361 or the upper end 363 and the lower end 361 of the venting hole 360, respectively A perforated processing method may be used.

In the above various methods, in order to form the ventilation hole 360 according to an embodiment of the present invention, a process for forming the central portion 362 extending in parallel with the upper surface of the detergent storage container 310 needs to be added. , when considering the extension direction of the central part 362, the process for processing the central part 362 may be more difficult than other processes.

However, in one embodiment of the present invention, by setting an overlapping area 369 between the upper end 363 and the lower end 361 of the ventilation hole 360 , the central portion 362 through the processing of the upper end 363 and the lower end 361 . ) can be induced.

For example, in the injection molding method, the upper mold for forming the upper end 363 of the ventilation hole 360 and the lower mold for forming the lower end 361 are spaced apart from each other on the central axis, but are arranged in a partially overlapping state along the vertical direction (Z). Thus, it is possible to process the ventilation hole 360 according to an embodiment of the present invention.

In addition, in the perforation method, the upper end 363 and the lower end 361 of the ventilation hole 360 by a certain depth are perforated, respectively, but if the upper end 363 and the lower end 361 are partially overlapped, one embodiment of the present invention and Likewise, the ventilation hole 360 having the overlapping area 369 may be machined.

As described above, one embodiment of the present invention forms a central portion 362 parallel to the upper surface of the detergent storage container 310, but forms an overlapping region 369 in which the upper end 363 and the lower end 361 overlap, thereby forming a ventilation hole 360) can be improved effectively and simply.

On the other hand, FIG. 34 shows the inside of the case 339 of the detergent storage container 310 in which a plurality of flow inhibiting walls 370 are formed according to an embodiment of the present invention, and FIG. 35 shows the detergent storage container 310 of FIG. ) is shown by incision along the GG line.

34 and 35 , an embodiment of the present invention is provided in plurality in the storage space and protrudes from the inner surface of the detergent storage container 310 to suppress the flow of the detergent toward the ventilation hole 360 . It may further include a flow inhibiting wall 370 that does.

The flow inhibiting wall 370 may be manufactured separately from the case 339 of the detergent storage container 310 and coupled to the case 339 , or may be integrally formed with the case 339 . The flow inhibiting wall 370 may be provided in plurality, and is coupled to the inner surface of the detergent storage container 310 to protrude from the inner surface, and may inhibit the flow of detergent stored in the detergent storage container 310 .

The kinetic energy of the detergent in the detergent reservoir 310 can be reduced by the flow-restricting wall 370 , and thus the possibility of leaking through the vent hole 360 can be reduced, which is advantageous.

On the other hand, the ventilation hole 360 is located at the front end of the upper surface, the flow restricting wall 370, is located in the rear of the ventilation hole 360, in a direction transverse to the front-rear direction (X) It includes an extended first restraining wall 371 , and the ventilation hole 360 may be located between the front surface of the detergent storage container 310 and the first restraining wall 371 .

Specifically, the ventilation hole 360 may be located on the upper surface of the detergent storage container 310 , for example, at the front end of the cap member 330 of the detergent storage container 310 . As described above, the front end of the detergent storage container 310 may correspond to the detergent input unit 313 .

The first restraining wall 371 may be located at the rear of the ventilation hole 360 . Accordingly, based on the front-rear direction (X), the ventilation hole 360 may be located between the front surface of the detergent storage container 310 and the first containment wall 371, and accordingly, the detergent flowing in the front-rear direction (X). The flow is blocked by the front surface and the first restraining wall 371 of the detergent storage container 310 and leakage through the ventilation hole 360 can be suppressed.

The first restraining wall 371 may extend in a direction transverse to the front-rear direction (X). For example, the first restraining wall 371 may extend in parallel with the lateral direction (Y) to block the movement of the detergent flowing in the front-rear direction (X). The first restraining wall 371 may protrude upward from the lower surface of the detergent storage container 310 or extend from the side in the lateral direction (Y).

On the other hand, as shown in FIGS. 34 and 35 , in an embodiment of the present invention, the ventilation hole 360 may be located on the edge side to which the side of the detergent storage container 310 is connected at the front end of the upper surface. have.

In addition, the flow restricting wall 370 may include a second restricting wall 372 positioned on the opposite side of the side with the vent hole 360 as the center and extending along the front-rear direction (X). , the ventilation hole 360 may be located between the side of the detergent storage container 310 and the second restraining wall 372 .

Since the ventilation hole 360 is located at the edge of the front end, the flow of detergent is restricted by the front and side surfaces of the detergent storage container 310 and the flow energy of the detergent toward the ventilation hole 360 can be reduced.

Also, the ventilation hole 360 may be disposed between the second restraining wall 372 and the side surface of the detergent storage container 310 . The second containment wall 372 may extend in parallel with the front-rear direction X, and accordingly, the detergent is ventilated along the lateral direction Y by the side surfaces of the second containment wall 372 and the detergent storage container 310 . Flow towards the hole 360 may be restricted.

In the detergent valve 380 , the rear end 382 may have a larger diameter than the insertion portion 383 . That is, the detergent valve 380 may be formed such that the rear end 382 is stepped with respect to the insertion portion 383 , and accordingly, the insertion distance of the detergent valve 380 may be limited.

In addition, since the front surface of the rear end 382 is supported on the rear surface of the detergent storage container 310 , a stable fixing structure of the detergent valve 380 can be implemented.

On the other hand, in an embodiment of the present invention, the rear end 382 of the detergent valve 380 may be formed with a plurality of grip grooves 384 spaced apart along the outer circumferential direction. The rear end 382 of the detergent valve 380 is exposed to the outside of the detergent storage container 310, and a grip groove 384 may be formed so that it can be easily gripped by a user.

The user may rotate the detergent valve 380 in the forward or reverse direction by gripping not only the limiting protrusion 381 but also the rear end 382 in which the grip groove 384 is formed.

Meanwhile, in an embodiment of the present invention, the coupling groove 385 may include a straight forward portion 386 and a rotating portion 387 . The straight portion 386 may have a front open front of the front end and extend rearward from the front end. The rotating part 387 may extend in a reverse direction opposite to the forward direction from the rear end of the straight forward part 386 .

The detergent valve 380 is inserted into the valve hole 397 so that the coupling protrusion 396 slides on the straight part 386 , and the coupling protrusion 396 slides on the rotating part 387 in the forward direction. may be rotated to be coupled to the valve hole 397 .

The coupling process of the detergent valve 380 according to the shape of the coupling groove 385 as described above will be described in detail as follows.

First, in FIG. 42 , the detergent valve 380 that starts to be inserted into the valve hole 397 is shown. The detergent valve 380 may be inserted into the valve hole 397 in a state in which the straight portion 386 of the coupling groove 385 and the coupling protrusion 396 are aligned to be positioned on a straight line in the front-rear direction (X), In this process, the coupling protrusion 396 may slide along the straight portion 386 of the coupling groove 385 .

Meanwhile, FIG. 43 shows a state in which the detergent valve 380 of FIG. 42 is inserted into the valve hole 397 . The detergent valve 380 may be inserted into the valve hole 397 by going straight so that the front surface of the rear end 382 comes into contact with the rear surface of the detergent storage container 310 . In this state, the coupling protrusion 396 may still be positioned on the straight portion 386 of the coupling groove 385 .

Meanwhile, FIG. 44 shows a state in which the detergent valve 380 of FIG. 43 is rotated in the forward direction to be in a closed state. The detergent valve 380 may be rotated in the forward direction while the front side of the rear end 382 is fully inserted so as to contact the rear surface of the detergent storage container 310 .

When the detergent valve 380 rotates in the forward direction, the coupling protrusion 396 may move along the rotating part 387 from the straight part 386 of the coupling groove 385 . As the detergent valve 380 rotates in the forward direction, the coupling protrusion 396 moves in the reverse direction with respect to the detergent valve 380 , so that the rotating part 387 may extend in the reverse direction from the straight forward part 386 .

The length of the rotating part 387 may correspond to a predetermined amount of rotation in the forward direction for the detergent valve 380 to be in a closed state. That is, when the detergent valve 380 is rotated in the forward direction and the coupling protrusion 396 is positioned at the end of the rotating part 387 of the coupling groove 385 , the detergent valve 380 is in a closed state and the coupling process is terminated.

Meanwhile, in an embodiment of the present invention, the straight portion 386 may extend backward from the front end of the detergent valve 380 , and the opened front surface may be located on the front surface of the detergent valve 380 .

Accordingly, when the rectilinear portion 386 and the engaging protrusion 396 are not aligned in a straight line, the insertion of the detergent valve 380 into the valve hole 397 may be restricted, and the user may use the current detergent valve 380 . ) to effectively identify the alignment status.

For example, when the open front of the straight forward part 386 is spaced apart from the front of the detergent valve 380 to the rear, the detergent valve 380 is engaged with the coupling protrusion 396 while being partially inserted into the valve hole 397 . Since the groove 385 is not aligned, further insertion is prevented. In this case, it may not be easy for the user to determine the alignment state of the engaging protrusion 396 and the engaging groove 385 .

Accordingly, according to an embodiment of the present invention, the user can easily identify the alignment state between the coupling protrusion 396 and the coupling groove 385 from the initial insertion of the detergent valve 380 with the naked eye, etc., so that the insertion of the detergent valve 380 is proceeded. make it possible

On the other hand, referring to FIGS. 43 and 44 , in an embodiment of the present invention, the forward stopper 391 may come into contact with the limiting projection 381 when the engaging projection 396 is positioned at the end of the rotating part 387 . can

As described above, the contact between the limiting protrusion 381 and the forward stopper 391 may assist in limiting rotation by the engaging protrusion 396 and the engaging groove 385 . Accordingly, when the engaging protrusion 396 is positioned at the end of the rotating part 387 in the engaging groove 385, the limiting protrusion 381 prevents further rotation while the rotation is restricted by the forward stopper 391 and prevents the engaging protrusion ( 396) can be prevented.

The entry part 388 may be formed on the rotating part 387 . That is, the entry part 388 may be formed at a portion connected to the straight part 386 in the rotation part 387 . In addition, the entry part 388 may be formed to have a narrower width than the rotation part 387 . Accordingly, the coupling protrusion 396 may generate resistance to movement in the process of passing the entry portion 388 .

Due to the entry part 388 , the user can feel resistance to rotation at the initial stage of rotation of the detergent valve 380 , and the coupling protrusion 396 is intact on the rotation part 387 according to the forward rotation of the detergent valve 380 . entry can be recognized.

In addition, when the coupling protrusion 396 is positioned at the end of the rotating part 387, when the detergent valve 380 is rotated in the reverse direction due to an unintended cause, the entry part 388 interferes with the movement of the coupling protrusion 396, It is possible to prevent the detergent valve 380 from being unintentionally rotated in the reverse direction to be converted to an open state.

Meanwhile, referring to FIG. 45 , the entry part 388 may have a side inclined so that the width becomes narrower toward the end of the rotation part 387 . That is, the entry portion 388 may be formed to be narrower as it goes away from the straight portion 386 .

The inclined side of the entry part 388 may have a straight inclined surface or may form a curved surface. In addition, the end portion from the entry portion 388 toward the rotation portion 387 may have a step shape in which the width is discontinuously expanded in relation to the rotation portion 387 .

In an embodiment of the present invention, the entry of the engaging protrusion 396 into the rotating part 387 may be induced when the detergent valve 380 rotates in the forward direction by the entry part 388 formed to be inclined on the side. When the valve 380 is unintentionally rotated in the reverse direction, the movement of the coupling protrusion 396 may be restricted by the entry part 388 .

That is, one embodiment of the present invention limits the forward rotation of the detergent valve 380 to a certain amount or less through the forward stopper 391, and at the same time, the reverse stopper ( 392) is used to prevent over-rotation of the detergent valve 380, thereby preventing damage to the coupling protrusion 396 and the like.

On the other hand, in an embodiment of the present invention, the limiting protrusion 381 may be in contact with the reverse stopper 392 when the coupling protrusion 396 is positioned on the straight portion 386 to limit the reverse rotation. .

When the detergent valve 380 is rotated in the reverse direction from the closed state to the open state, the coupling protrusion 396 moves from the end of the rotating part 387 toward the straight part 386, and the coupling protrusion 396 has the straight part ( 386), the reverse stopper 392 limits the reverse rotation of the limiting protrusion 381, thereby preventing the engaging protrusion 396 from being damaged by being pressed by the side of the straight forward part 386.

On the other hand, in an embodiment of the present invention, the detergent storage container 310 is engraved with a closing mark 393 at a position corresponding to the forward stopper 391 on the rear surface, and the reverse stopper 392 at a position corresponding to the position. An open mark 394 may be engraved.

For example, words expressing opening and closing in Korean or English may be engraved, and specific shapes such as open and closed locks may be engraved as shown in FIGS. 38 and 39 . The method of engraving may also vary, such as intaglio or embossing.

In the state in which the detergent valve 380 is inserted, the forward direction for the closed state or the reverse direction for the open state of the detergent valve 380 may be ambiguous to the user. A forward stopper 391 and a reverse stopper 392 for limiting the rotation of the forward stopper 391 and the reverse stopper 392 are engraved with a closed mark 393 and an open mark 394 respectively on or around the forward stopper 391 and the reverse stopper 392 By doing so, the user can effectively recognize the forward and reverse directions and the open or closed state accordingly.
