Washing machine, detergent box assembly

Description

[0001]

The present invention relates to a washing machine, and more particularly, to a washing machine having a detergent box assembly that is easy to use.

Generally, the washing machine includes a dryer for drying laundry, a washing machine for washing laundry, and the like. Among these washing machines, a washing machine, in particular, uses a detergent or the like for washing. To this end, a washing machine generally includes a detergent box assembly for injecting a detergent. Therefore, the detergent box assembly can be said to be self-evident in a washing machine.

The detergent box assembly has a detergent receiving part for receiving the detergent, and the detergent is supplied to the tub or the drum, which is a space for washing together with the washing water, into the space.

Most of the conventional detergent box assemblies are provided at one side of a cabinet constituting the outer shape of the washing machine, and the detergent containing portion is selectively exposed to the outside by a user. The detergent box assembly may be formed, for example, in a drawer type on the front surface of the cabinet or on a top surface of the cabinet in a lid type.

The problem is that in any case, when the washing water is supplied to the detergent receiving portion, the washing water leaks to the inside or outside of the cabinet. For example, there is a risk of damaging electric parts when the water leaks to the inside of the cabinet, and when the water leaks outside the cabinet, the aesthetics of the washing machine may be deteriorated and secondary contamination may be caused to the outside. Therefore, it is a natural problem to prevent the wash water from leaking through the detergent box assembly in the detergent box assembly.

In addition, a solid detergent such as a powder detergent is often used as a detergent for washing. However, a phenomenon that solid detergent is hardly washed or dissolved by washing water in the detergent receiving part frequently occurs. That is, once the powdered detergent is wetted, it does not dissolve and becomes hardened, so that it sticks to the detergent receiving portion and does not decompose well. Therefore, it is a natural problem to prevent contamination of the detergent box assembly due to the solid detergent when a solid detergent is used.

In addition, in recent years, there has been an increasing tendency to use liquid detergents as well as such solid detergents. Liquid detergents are very easy to decompose as compared to solid detergents and thus less likely to contaminate detergent box assemblies. However, depending on the user's tendency, whether liquid detergent or solid detergent is used may vary. Thus, the need for a detergent box assembly that meets the diversity of these detergents is also natural.

In addition to liquid detergents, recently, a lot of fabric softeners have been used to provide a fragrance and a softness to a laundry after a simple detachment from the laundry concept. However, since the fabric softener is used in rinsing, when supplying the washing water to the detergent box assembly for washing, the washing water should not be mixed with the fabric softener.

As a result, there is a need to provide a detergent box assembly that meets the needs of various users in view of the type of detergent that can be used, the fabric softener, and the like.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a washing machine which can be easily and conveniently used by a user by improving a detergent box assembly in a conventional washing machine.

And more particularly, to provide a washing device that can be used safely and cleanly by preventing the washing water from leaking to the inside or the outside of the washing machine through the detergent box assembly.

In addition, when a solid detergent is used, the detergent is prevented from remaining in the detergent box assembly and contaminated, and the detergent can be sufficiently dissolved in the detergent box assembly in the first place, so that the detergent residue can be prevented from remaining in the laundry after the washing The present invention relates to a washing machine having a washing machine.

Another object of the present invention is to provide a washing device which is suitable for use in response to a change in the user's demand such as the type of detergent and the fabric softener.

According to an aspect of the present invention, there is provided a washing machine comprising a cabinet, a tub for storing wash water, and a detergent box assembly for supplying detergent and washing water to the tub, A detergent box body including a detergent receiving portion and an outlet through which wash water and detergent are discharged; And a detergent box cover provided on the top of the detergent box body and formed around the detergent receiving part to supply wash water to the detergent receiving part.

Preferably, the washing water channel is provided with a plurality of inflow openings for supplying washing water to the detergent receiving part in the radial direction. And the inlet may be formed in the form of a partition for a slit, a through hole, or an overflow. That is, it is preferable that some of the wash water is radially released and supplied to the detergent receiving portion while the wash water flows along the flow path.

In addition, it is preferable that at least a part of the washing water flow path is formed on the same plane as an inlet and an outlet, and a section between the inlet and the outlet is formed so as to surround at least three sides of the detergent receiving part Do.

Meanwhile, the detergent receiving portion may include the detergent receiving portion provided to receive a solid detergent. A solid detergent here can generally refer to a detergent in powder form. Of course, this detergent receiving portion is not necessarily capable of receiving solid detergent. That is, this means the manufacturer's recommendation, so liquid detergent may be contained in the present detergent receiving part.

The washing water passage may include a hot water passage for supplying hot water to the detergent receiving portion and a detergent cold water passage for supplying cold water to the detergent receiving portion. The starting end of the hot water channel may be connected to the hot water inlet and the starting end of the present detergent cold water channel may be connected to the detergent cold water inlet.

The hot water flow path and the present detergent cold water flow path may be configured so that at least some sections are communicated with each other. Herein, the section may be a portion surrounding the present detergent receiving portion. Therefore, irrespective of whether hot water or cold water is supplied, the washing water can be always supplied to the detergent receiving part uniformly.

It is preferable that a drain port for draining wash water from the detergent box body is formed in the vicinity of the hot water inlet of the hot water channel and the cold water inlet of the present detergent cold water channel. This is to prevent the hot water introduced into the hot water channel from flowing into the cold water inlet or vice versa.

The detergent receiving portion may include a detergent receiving portion provided to receive a solid detergent. Here, the pre-detergent receiving portion may be provided separately from the present detergent receiving portion. In this case, the distinction between the detergent and the preparative detergent is necessary because the detergent necessary for the avalanche is a preparatory detergent, and it is a detergent necessary for the main laundry after the avalanche.

Here, the wash water flow path may include a cold water flow path for supplying cold water to the pre-detergent receiving part. In addition, the starting end of the pre-cleaner cold water channel may be connected to the cold water inlet of the pre-cleaner, and the end of the pre-cleaner cold water channel in the flow direction may be clogged. At this time, it is preferable that a plurality of partition walls are formed in the pre-cleaner cold water passage so that cold water overflows to the pre-detergent storage portion in a radial direction. Of course, the partition may be formed as a slit or a through hole as described above.

Further, the height of the partition wall may be changed along the cold water passage of the pre-cleaner. For example, it is preferable that the height of the partition at the end of the cold water flow path is relatively higher as the cold water flow path progresses. This is to sufficiently supply wash water to the distal end of the cold water flow path so as to supply the wash water sufficiently in all directions surrounding the detergent receiving portion.

Preferably, a residual water drain port having a height less than a bottom surface of the pre-cleaner cold water channel is formed at a distal end portion of the pre-cleaner cold water channel. This is to prevent the washing water from remaining in the flow channel when the supply of the washing water is completed.

Meanwhile, the pre-detergent receiving portion and the pre-cleaner cold water passage may be replaced with the present detergent receiving portion and the detergent cold water passage. Therefore, as described above, the distinction between the present detergent and the pre-detergent is different depending on whether or not the wash water is supplied to the detergent containing the detergent.

According to another aspect of the present invention, there is provided a washing machine comprising a detergent box assembly for supplying detergent and washing water to a tub, the detergent box assembly comprising a solid detergent container and a liquid detergent container A detergent box body including a detergent receiving portion having a portion for discharging washing water and a detergent; And a detergent box cover provided on the upper part of the detergent box body, wherein the detergent channel is formed along the periphery of the solid detergent housing part and supplies the washing water to the solid detergent housing part A washing machine comprising a solid detergent laundry water channel.

The washing water flow path may include a liquid detergent washing water flow path branched from the solid detergent washing water flow path and supplying washing water to the liquid detergent receiving portion. In addition, it is preferable that a guide portion is formed on the solid detergent wash water flow path so as to smoothly guide some of the washing water to the liquid detergent receiving portion.

Further, the detergent box body may further include a second solid detergent receiving portion, and the liquid detergent receiving portion may be located between the solid detergent receiving portions. For example, if two solid detergent receptacles are provided, one may be referred to as the detergent receptacle and the other as the detergent receptacle.

The washing water flow path may include a second solid detergent wash water flow path formed around the second solid detergent receiving part to supply washing water to the second solid detergent receiving part.

Meanwhile, the liquid detergent receiving portion may further include a fabric softening agent accommodating portion. That is, a space in which the liquid detergent is accommodated may be formed on one side, and a space may be formed on the other side to accommodate the fabric softening agent.

In this case, the washing water flow path may further include a fabric softening agent flow path for supplying washing water to the fiber softening agent receiving portion between the solid detergent washing water flow path and the second solid detergent washing water flow path.

The fabric softener wash water flow path may be configured such that wash water flows into the solid detergent wash water flow path due to the offset of the momentum between the solid detergent wash water flow path and the inflowing wash water when the wash water flows into the second solid detergent wash water flow path.

The detergent box cover may include a top cover having a mouth for introducing the detergent into the detergent housing part and a guide rib for surrounding the inlet so as to smoothly supply the washing water to the detergent housing part; And a lower cover coupled to the upper cover and configured to form the wash water flow path therein.

According to another aspect of the present invention, there is provided a washing machine comprising a cabinet, a tub for storing wash water, and a detergent box assembly for supplying detergent and washing water to the tub, A detergent box body having a detergent receiving portion, an outlet for discharging washing water and detergent; And a detergent box cover having an upper cover formed with an inlet for introducing detergent into the detergent receiving portion and a lower cover configured to be connected to the upper cover to form a washing water flow path for supplying washing water to the detergent receiving portion Thereby providing a washing device.

Here, the upper cover may include a guide rib configured to surround the inlet so as to smoothly supply the wash water to the detergent receiving portion. The washing water channel may be formed along the circumference of the detergent receiving part to supply the washing water in a radial direction. In this case, the guide rib is configured to guide the washing water introduced in the radial direction downward. That is, it is preferable that the washing water is guided downward to prevent washing water from splashing around.

Wherein the lower cover is formed with a lower extension portion extending upwardly and connected to the upper cover to form an outer wall of the laundry channel. The upper cover may be formed with an upper extension extending downwardly and connected to the lower extension to form an outer wall of the wash channel. Accordingly, the upper cover and the lower cover may be coupled to each other to form a flow path coupling portion constituting the outer side wall of the washing water flow path.

Here, the outer side wall of the washing water flow path means a wall forming the washing water flow path on the opposite side of the inner side wall surrounding the detergent receiving portion. Therefore, the washing water is supplied to the detergent receiving portion through the inner wall without passing the washing water through the outer wall.

In the meantime, the detergent box body is preferably provided with a groove for receiving at least a part of the wash water flow path formed by the detergent box cover. That is, at least a part of the washing water flow path is accommodated in the groove, so that the detergent box cover can be stably fixed to the detergent box body.

Preferably, the detergent box body is formed with a cover engaging portion which is coupled to the outer cover at an outer side of the outer wall or the outer wall of the washing water channel. The cover coupling portion may be formed by hook coupling or the like.

Here, it is preferable that the cover coupling portion is formed on the horizontal reference relative to the flow coupling portion. This is because even though the clearance is formed in the passage connecting portion and the wash water leaks through the clearance, the height of the cover engaging portion is higher, so that the wash water can be prevented from leaking to the outside of the detergent box assembly through the cover engaging portion. In addition, the flow path coupling portion may be formed by heat fusion or vibration fusion.

Meanwhile, the cabinet may include a top plate having an opening formed therein, and the detergent box cover may be fixed to the top plate below the opening. The detergent box assembly may include a detergent box frame provided at an upper portion of the opening and coupled to the detergent box cover to be adhered to the top plate.

The detergent box assembly may include a detergent box lid rotatably connected to the detergent box frame at one side thereof and configured to selectively open and close the opening.

Preferably, the upper surface of the upper cover is formed with a leakage preventing rib located to surround the outer periphery of the opening. This is to prevent water from flowing into the cabinet through the detergent box assembly even if water flows in from the outside of the cabinet through the opening.

In addition, it is preferable that a boss for screwing or riveting the upper cover to the detergent box frame is formed inside the leakage preventing rib. This is also intended to prevent the inflow of water introduced through the screw or rivet into the cabinet.

It is preferable that a plurality of the detergent receiving portions are provided and a plurality of the washing water flow paths are provided so as to correspond to the plurality of detergent receiving portions. Preferably, the lower cover is formed with a residual water drain hole configured to supply wash water, which is not supplied to the detergent receiving portion, to the outside of the washing water flow path, to the detergent box body. Residual water can be prevented from remaining in the detergent box assembly through the residual water drain hole, thereby maintaining a cleaner and more pleasant environment.

According to the present invention, a detergent box assembly in a conventional washing machine can be basically improved to provide a washing machine which can be easily and conveniently used by a user.

More specifically, it is possible to provide a washing machine that can be used safely and cleanly by preventing the water from leaking into the washing machine or the outside through the detergent box assembly.

In addition, when a solid detergent is used, the detergent is prevented from remaining in the detergent box assembly and contaminated, and the detergent can be sufficiently dissolved in the detergent box assembly in the first place, so that the detergent residue can be prevented from remaining in the laundry after the washing The washing machine can be provided.

In addition, it is possible to provide a washing device which is suitable for use and is convenient to use in response to a change in the user's demand such as the type of detergent and the fabric softener.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a washing machine as described above, and more particularly to a detergent box assembly. The configuration of the washing machine other than the detergent box assembly may be the same as that of the general washing machine, and the technical idea of the present invention is not limited to such a configuration. Therefore, embodiments of the present invention will be described with the center of the detergent box assembly as an example, and description of a general washing machine configuration will be omitted.

The washing apparatus according to an embodiment of the present invention includes a cabinet (not shown), a tub, and a detergent box assembly 100.

The cabinet forms the outer shape of the washing machine and accommodates various components therein. FIG. 1 shows a top plate 170, which is part of such a cabinet, which forms the top surface of the cabinet. In addition, the tub is configured to be supplied with detergent together with washing water to be stored therein, and the laundry is washed while rotating the drum. As described above, the configurations of the cabinet, the tub, and the like are a general configuration, and a detailed description thereof will be omitted.

The detergent box assembly 100 includes a detergent receiving body 161 and a detergent box body 160 including an outlet 165 through which wash water and detergent are discharged. The detergent receiving portion 161 is configured to receive the detergent and is inclined downward toward the outlet 165 so that the detergent and the washing water can be smoothly discharged to the outlet 165.

The detergent box assembly 100 includes a detergent box cover 130 provided at an upper portion of the detergent box body 160 to supply wash water to the detergent receiving portion 161. In the detergent box cover 130, wash water passages 310, 320, 330 and 340 are formed.

Here, a plurality of the wash water flow paths may be formed. Also, a plurality of detergent receiving portions corresponding to the plurality of wash water flow paths may be formed. FIG. 2 shows an example in which four wash water flow paths are formed and three detergent receiving portions are formed. Of course, a separate detergent box 150 may be divided into two or more detergent receptacles.

At least a part of the wash water flow path is formed along the circumference of the detergent receiving portion 161 to supply wash water to the detergent receiving portion.

First, a description will be given of the present detergent receiving portion 162 of the detergent receiving portion 161 and the detergent cold water flow path 320 for supplying washing water to the present detergent containing portion of the washing water flow path. Here, the term " detergent " refers to a detergent used in the present laundry. Therefore, the present detergent may be replaced with a pre-cleaner used for pre-washing, and in this case, the present detergent cold water passage 320 may be replaced with the pre-cleaner cold water passage 340.

2, the detergent cold water flow path extends from the rear of the detergent box cover 130 until it surrounds at least the detergent receiving portion 162 as seen in FIG. That is, it is formed so as to at least surround the left and right and front sides of the present detergent receiving portion.

In addition, the washing water flow path, in particular, the detergent cold water flow path is provided with a plurality of inflow openings for supplying washing water to the detergent receiving portion, particularly the present detergent receiving portion, in a radial direction. Such an inlet may be formed in the form of a partition for a slit, a through hole, or an overflow. Details will be described later.

On the other hand, hot water as well as cold water can be used for washing. Therefore, it is preferable that the washing water flow path includes the hot water flow path 310.

The hot water passage 310 is also formed along the periphery of the present detergent receiving portion 162. In addition, it is preferable that a plurality of inlets for supplying wash water in the radial direction are formed.

The hot water passage 310 may be separated from the detergent cold water passage 320. However, it is preferable that the hot water passage 310 and the present detergent cold water passage 320 are formed so as to be at least partially common to each other in order to limit the space and make it easier.

2, the detergent cold water flow path 320 starts from the cold water inlet port 363 provided at the rear of the detergent box cover 130 to cover the detergent receiving portion, To the hot water inlet 361 provided at the rear of the hot water inlet 361. Of course, the present detergent cold water flow path 320 may be defined as a point 315 surrounding the three sides of the present detergent receiving portion.

In addition, the hot water passage 310 may extend from the hot water inlet 361 to the cold water inlet 363 after wrapping the detergent receiving portion. Of course, the hot water passage 310 can be defined as a point 325 surrounding the present detergent receiving portion.

The point 325 may be an inlet through which the wash water flows from the viewpoint of the detergent cold water flow path 320 and the point 315 may be an outlet through which wash water flows. Therefore, it is preferable that the interval between the inlet and the outlet of the wash water flow path is formed so as to completely surround the detergent receiving portion. Here, the complete enclosure may surround the four sides of the detergent receiving part, but may mean at least three sides of the detergent receiving part. Therefore, it is preferable that the inlet and the outlet are formed on the same plane.

That is, the wash water flows in the radial direction between the inlet and the outlet, and the detergent and the wash water flow to the rear of the detergent box assembly. Accordingly, since the washing water flows into the detergent receiving portion in the direction in which the detergent and the washing water flow out, that is, in all directions except the rear, the washing water can be uniformly supplied to the detergent receiving portion and the detergent contained therein.

The detergent does not remain in the detergent receiving portion due to the supply direction of the washing water and the detergent is prevented from being bundled, thereby preventing contamination of the detergent box assembly. Also, since the detergent is dissolved in the detergent box assembly primarily, it is possible to minimize the detergent remaining in the laundry after the completion of washing.

This effect may be more pronounced in particular when a detergent such as a powder detergent is contained in the detergent receiving part.

On the other hand, it is not preferable that the wash water flowing along the detergent cold water passage 320 continuously flows into the hot water inlet 361. The reverse is also true. Therefore, the inlet 325 and the outlet 315 may be provided with drain holes for draining the washing water from the detergent box body. Of course, the drains 311 and 321 may be formed in the vicinity of the hot water inlet of the hot water passage and the cold water inlet of the detergent cold water passage, respectively, as shown in FIG.

The detergent receiving portion 161 may include a detergent receiving portion 164. In addition, the washing water flow path may include a pre-cleaning water channel 340 for supplying cold water to the pre-detergent receiving portion. Of course, such a reservoir containing portion and a pre-cleaner cold water passage may be replaced with the present detergent containing portion and the present detergent cold water passage. However, in any case, the end of the cold water flow path 340 is preferably closed.

That is, the starting end of the pre-cleaner cold water passage 340 is connected to the pre-cleaner cold water inlet 362, and the end of the pre-cleaner cold water passage 340 in the flow direction is blocked. In Fig. 2, the end 341 of the blocked cold water flow path 340 is shown. In this case, since it means that the flow path is no longer extended, it is preferable that the washing water is radially discharged from the distal end portion. That is, the end portion may have the same configuration as the inlet 325 or the outlet 315 described above.

Hereinafter, the structure for introducing the washing water into the detergent receiving portion will be described in detail with reference to FIG.

The same description may be applied to the detergent cold water flow path 320 described above. 3 shows the lower cover of the detergent box cover. The upper cover and the lower cover may be separately manufactured and joined together, but the upper cover and the lower cover may be integrally manufactured.

The pre-cleaner cold water passage 340 is formed inside the detergent box cover 130. And the upper cover and the lower cover may be combined. In any case, it is preferable that the outer wall, i.e., the outer wall of the pre-cleaner cold water passage 340 is closed. Of course, it is preferable that the upper and lower portions of the flow path are also closed. However, it is preferable that the inner side wall is opened in various forms along the pre-cleaner cold water passage 340 so that the wash water flows in the radial direction of the detergent receiving portion along the inner side wall.

As shown in FIG. 3, a plurality of partition walls 341 and 342 may be formed along the inner wall 343 of the cold water passage 340. First, the washing water overflows over the inner side wall, thereby supplying the washing water to the detergent receiving portion in the radial direction. Also, it can be overflowed through a plurality of partitions, which function to disperse the amount of wash water overflowing as a whole. However, it is preferable that the partition wall at the end portion of the flow passage is configured to be higher than the partition wall of the other portion. That is, sufficient washing water is supplied to the end of the flow path.

In addition, at the end of the flow path 340, a residual water discharge port 345 formed below the bottom surface of the flow path is preferably formed. Therefore, it is possible to drain water without remaining water on the flow path. In this case, the residual water drain hole may be formed in a slit shape or a through hole shape.

In addition, the partition may be replaced with a through hole or a slit. In any case, it is preferable that the washing water is formed so as to be uniformly supplied to the detergent receiving portion along the flow path.

Meanwhile, in the embodiment of the present invention, the detergent box assembly 100 may be formed to have the detergent receiving portion 162 and the detergent receiving portion 164, respectively, in which the solid detergent is received. Here, the latter may be referred to as a second solid detergent receptacle. Further, a liquid detergent receiving portion 163 may be further provided between the detergent receiving portion and the pre-detergent receiving portion to receive the liquid detergent.

Here, it is necessary to supply wash water also to the liquid detergent receiving portion 163. However, the liquid detergent can be easily supplied to the tub without being dissolved in the washing water and remained in the detergent receiving portion even if a large amount of the washing water is not supplied. Therefore, unlike the other flow path described above, it is not necessary to form the liquid detergent wash water flow path 330 for supplying the washing water to the liquid detergent receiving portion so as to surround the liquid detergent receiving portion 163.

As shown in FIG. 2, the detergent box cover 130, particularly the lower cover 300, is formed with a liquid detergent washing water flow path 330 branched from the detergent cold water flow path 320. It is preferable that the guide 332 is formed on the detergent cold water flow path 320 so that a part of the washing water can be smoothly introduced into the liquid detergent washing water flow path 330. Such a guide portion may be formed in a curved shape or a guide rib shape or the like.

On the other hand, a discharge hole 331 for discharging wash water is formed at the distal end of the liquid detergent wash water flow path 330.

Therefore, when the user puts the liquid detergent into the liquid detergent receiving part for the main washing, the washing water flows into the detergent cold water passage 320, a part thereof flows into the liquid detergent washing water passage 330, 163, and a part thereof flows into the detergent accommodation portion. Of course, the detergent and the washing water are combined at the rear lower portion of the detergent box body and discharged to the discharge port 165.

The liquid detergent may comprise a fabric softener. Therefore, liquid detergent for washing and fabric softener should be distinguished. This is because each function is different and the time of supplying the tub to the washing machine is different.

Therefore, it is preferable that the liquid detergent receiving portion 163 is divided through a separate detergent box 150. In addition, it is preferable that the detergent box is provided with a siphon cap configured to supply a liquid detergent or a fabric softening agent using a siphon phenomenon due to its liquid nature. The construction of the siphon cap is obvious to those skilled in the art, so a detailed description thereof will be omitted.

On the other hand, the liquid detergent wash water flow path 330 supplies wash water to the liquid detergent receiving portion for washing, among the liquid detergent receiving portion. Accordingly, it is preferable that a flow path for supplying the fabric softener to the detergent box 150 is provided separately. Meanwhile, since the fabric softening agent is required in the rinsing process, it is preferable that washing water is not supplied to the portion where the fabric softening agent is contained in the washing process.

For this purpose, it is preferable that the fabric softener wash water channel 350 is separately formed. The fabric softener wash water channel 350 is preferably provided between the present detergent wash water channel 320 and the pre-detergent wash water channel 340. The detergent wash water flow path and the pre-detergent wash water flow path are connected to the cold water inflow ports 362 and 363, respectively. The cold water inflow ports may be formed in directions intersecting with each other. That is, the cold water inlets and the fabric softener wash water channel may be arranged in a Y shape. Therefore, when the cold water, which is cold water, flows in the cold water inflow ports at the same time, the flow direction of the wash water changes due to the offset of the momentum between the wash water. That is, the momentum directed to both sides is canceled and the wash water flows in the center direction, and the fabric softener wash water channel 350 may be formed along the center direction.

Therefore, during the washing process, the washing water may be introduced into only one of the detergent washing water flow path and the preliminary washing water flow path, and the washing water may be simultaneously introduced into the washing water flow path during the rinsing process. Thus, washing water can be introduced into the fabric softener wash water channel only during the rinsing process. Of course, a discharge hole 351 for supplying wash water may be formed at the end of the fabric softener wash water channel 350.

Hereinafter, an assembling process of the detergent box assembly 100 according to an embodiment of the present invention will be described.

First, the detergent box assembly 100 is not provided in the form of a drawer on the front surface of the cabinet but may be provided on the top plate 170. That is, the user may be configured to supply the detergent through the opening 171 formed in the top plate 170.

A detergent box frame 120 is inserted into the opening 171 for coupling the top plate and the three-dimensional cutter box assembly. An opening 121 is formed at the center of the detergent box frame 120 so that the user can supply the detergent through the opening.

Meanwhile, the detergent box frame 120 is in close contact with the top plate 170. Therefore, water can be prevented from flowing into the cabinet through the gap between the detergent box frame 120 and the top plate 170. A sealing may be further provided if necessary.

However, the lid 110 is coupled to the detergent box frame 120, and the lid may include a hinge structure or the like to be rotatable. Therefore, due to the hinge structure and the like, there is room for water to flow into the cabinet through this portion. Therefore, a detergent box cover can be formed as described below to eliminate the space in which such water is introduced into the cabinet.

The detergent box cover may be connected to the top plate 170 from the bottom of the top plate 170. Of course, it can be fixed to the top plate by engaging with the detergent box frame 120.

Here, the detergent box cover 130 may have a single structure or may be formed by combining the upper cover 200 and the lower cover 300. In this case, the upper cover and the lower cover are defected from each other, thereby forming a washing water flow path for supplying washing water to the inside.

The detergent box cover is provided with a charging port 166 for charging detergent. A guide rib 167 may be formed to surround the inlet so as to smoothly supply the washing water to the detergent receiving portion.

The guide ribs 167 guide the wash water flowing in the radial direction downward. That is, the flow direction of the washing water is smoothly guided downward to prevent the washing water from splashing in the detergent receiving portion. Therefore, the washing water can be prevented from being contaminated by the detergent containing portion.

Meanwhile, when the detergent box cover is composed of the upper cover and the lower cover, the inlet 167 and the guide rib 167 are preferably formed on the upper cover.

In addition, the upper cover and the lower cover may be coupled to each other to form a washing water channel. To this end, the lower cover may be formed with a lower extension 310 extending upward to form an outer wall of the washing water channel . The upper cover may have an upper extension 210 extending downward and coupled with the lower extension 310. Accordingly, the lower extension 310 and the upper extension 210 are coupled to each other by vibration welding, heat fusion, or the like to form a flow path coupling part 320 constituting the outer side wall 330 of the washing water flow path.

The detergent box cover 130 is joined at the top of the detergent box body 160 where the detergent is received. This coupling may be a hook coupling. In order to further strengthen the coupling, the detergent box body 160 may be provided with a groove 166 for receiving at least a portion of the wash water flow path formed by the detergent box cover.

In addition, the detergent box body is formed with a cover coupling part 220 which is coupled to the upper cover on the outer side of the outer wall of the washing water channel. The cover coupling portion may be a portion where the upper cover contacts the detergent box body.

Here, it is a matter of course that the flow path coupling portion 320 is formed to have no gap along the flow path. However, due to the difference in dimensional error and the inaccuracy of the joint, there is room for some gaps to be generated. Therefore, there is a fear that the washing water leaks to this portion. Therefore, it is necessary to prevent the leaked wash water from being discharged to the outside of the detergent box assembly 100.

For this, the cover coupling part 220 is preferably formed on the horizontal reference relative to the flow coupling part 320. Therefore, even if the wash water leaks once through the flow path coupling portion, the wash water is not leaked to the outside through the cover coupling portion due to the height difference.

Accordingly, the detergent box body 160 is engaged with the detergent box cover 130 and fixed to the lower portion of the top plate 170 through the detergent box cover.

Here, it is preferable that a leakage preventing rib 230 is formed on the upper part of the detergent box cover 130. It is preferable that the leakage preventing ribs 230 are positioned to surround the outer periphery of the opening 171 of the top plate 170. Therefore, the water introduced into the opening 171 is not discharged to the outside due to the leakage preventing rib 230. Therefore, water can be prevented from flowing into the cabinet in advance.

A boss 240 may be formed on the inside of the leakage preventing rib 230 to connect the upper cover to the detergent box frame 120 or the top plate 170. And can be coupled through the boss portion 240 through screws or rivets. In addition, even if water flows through the screw or the like, the boss is positioned inside the leakage preventing rib, so that water is prevented from escaping to the outside.

2, reference numeral 370 denotes a residual water drain hole. The residual water drain hole functions to discharge the wash water leaking to the outside of the wash water flow path to the detergent box body 160. Therefore, it is possible to effectively prevent the water from remaining in the detergent box assembly and decaying.
