[0005]

DISCLOSURE OF THE INVENTION A detergent introducing device for a washing machine according to the present invention is provided in a bottom portion which is formed in a substantially box shape and is inclined so as to be lowered toward one side and one side portion of the bottom portion. With a detergent storage container having a discharge port
A water injection member having a water injection port for injecting water to the discharge side in the detergent storage container according to a water supply operation is provided, and the water injection member is provided below the water injection port and is inclined so as to become lower toward the opposite side of the discharge port. It is characterized in that it is provided with an inclined surface portion, and is provided with a guide member for guiding the water containing the detergent discharged from the discharge port of the detergent storage container into the washing tub.

In this structure, it is preferable that the inclined surface portion is formed integrally with the handle portion attached to the front portion of the detergent storage container. Further, the opening edge portion of the discharge port in the bottom surface portion of the detergent storage container is a horizontal surface, an inclined surface having a gentler angle than the other portions, or an inclined surface inclined so as to be higher toward the discharge port, and It is more preferable to set the height of the opening edge portion to be higher than the lowest point portion of the bottom surface portion. Further, it is also a good configuration to lower part of the opening edge portion. Further, it is also preferable that the lower end portion of the side wall portion on the discharge port side of the detergent storage container is configured to extend below the position where the opening edge portion is raised.

On the other hand, in the integrated body of the inclined surface portion and the handle portion,
A pair of wall portions may be provided so as to form a fitting groove that fits in the upper portion of the side wall portion on the discharge port side of the detergent storage container. An engaging portion is provided on at least one of the pair of wall portions, and an engaged portion is provided on the side wall portion of the detergent storage container on the discharge port side so as to engage with the engaging portion. This is the preferred configuration. Further, it is more preferable that the engaging portion is provided on the inner wall portion of the pair of wall portions. Furthermore, the front wall portion of the pair of wall portions is flush with the front surface of the side wall portion on the outlet side of the detergent storage container, or
It is also a good configuration to be provided behind the front surface.

Further, it is preferable that a clearance is provided in a rear portion and a lower portion between the detergent storage container and the guide member, and a water injection port for injecting water into the clearance is provided in the water injection member. Furthermore, it is an even more preferable configuration to bring the tip of the water injection member into contact with the upper end of the inclined surface.

[0009]

According to the above means, the inclined surface portion is provided below the water inlet of the water inlet member so as to be lowered toward the side opposite to the outlet, and the bottom surface portion of the detergent storage container is directed toward the outlet. Since it is configured to incline so as to be low, the water injected from the water injection port flows along the inclined surface part and goes to the opposite side of the discharge port, where after thoroughly stirring the detergent, the water is discharged along the bottom part. It flows toward and is discharged.
For this reason, the water injected from the water injection port will not be scattered in the detergent storage container, and the detergent in the detergent storage container will be sufficiently stirred by the water.
As a result, even when the amount of detergent is small or the force of water is strong, the detergent is sufficiently stirred in the detergent storage container, and the detergent is not left in the detergent storage container or the guide member.

By the way, in the detergent introducing device having such a structure, when the detergent is put in the detergent storage container and stored therein, if the amount of the detergent is large, the detergent may leak from the outlet. . On the other hand, in the above configuration, since the inclined surface portion is provided so as to be inclined toward the side opposite to the discharge port, the inclined surface portion can prevent the detergent from approaching the discharge port as much as possible, and Even if the amount is large, the detergent hardly leaks from the outlet.

Further, in the case of the above construction, if the inclined surface portion is formed integrally with the handle portion attached to the front portion of the detergent storage container, the number of parts can be reduced and the construction can be simplified. Further, the opening edge portion of the discharge port in the bottom surface portion of the detergent storage container is a horizontal surface, an inclined surface having a gentler angle than other portions, or an inclined surface inclined so as to be higher toward the discharge port, and If the height of the edge portion is higher than that of the lowest point portion of the bottom surface portion, it is possible to more reliably prevent the detergent from leaking from the discharge port. Furthermore, when the opening edge portion is configured to be partially lowered, all the water can be discharged from this lower portion, so that the water can be prevented from remaining in the detergent storage container. In addition, when the lower end of the side wall of the detergent storage container on the outlet side is configured to extend downward from the position where the opening edge is raised, the water discharged from the outlet hits the lower end of the side wall. To fall downward from. This can prevent the water discharged from the discharge port from jumping forward.

On the other hand, in the integrated body of the inclined surface portion and the handle portion,
If a pair of wall portions are provided so as to form a fitting groove that fits on the upper portion of the side wall portion on the discharge port side of the detergent storage container, a pair of wall portions are attached when the integrated product of the inclined surface portion and the handle portion is attached to the detergent storage container. The fitting can be performed only by fitting the fitting groove of the wall portion of the wall portion to the side wall portion, and the assemblability is improved. In this case, the engaging portion is provided on at least one of the pair of wall portions, and the engaged portion is provided on the side wall portion on the discharge port side of the detergent storage container so as to engage with the engaging portion. Assembling work becomes easier.

If the engaging portion is provided on the inner wall portion of the pair of wall portions, the outer appearance is improved because the engaging portion is not visible. Further, if the front wall portion of the pair of wall portions is provided so as to be flush with the front surface of the side wall portion on the discharge port side of the detergent storage container, or to be positioned rearward of the front surface, The front wall does not project from the front surface of the wall of the detergent storage container, and it is possible to prevent the user's finger or the like from being caught on the front wall.

On the other hand, when a gap is provided in the rear portion and the lower portion between the detergent storage container and the guide member, and a water injection port for injecting water into the gap is provided in the water injection member, the detergent storage container is discharged to the guide member. The discharged water and detergent can be reliably swept toward the washing tub by the water poured into the gap, and the detergent can be prevented from remaining on the guide member. Further, when the tip of the water injection member is brought into contact with the upper end of the inclined surface portion, the water injected from the water injection port of the water injection member into the detergent storage container overflows in the detergent storage container and tries to return upward. Even if a phenomenon occurs, since the tip of the water injection member is in contact with the upper end of the inclined surface portion, it is possible to reliably prevent the water from overflowing to the upper side of the water injection member.

As a result, even when the amount of detergent is small or the force of water is strong, it is ensured that the detergent is sufficiently stirred in the detergent storage container 43 and that the detergent remains in the detergent storage container 43 and the guide surface portion 32. Can be prevented.

By the way, in the detergent charging device 22 having the above-mentioned structure, when the powder detergent is charged into the detergent storage container 43, since the discharge port 46 is formed in the front part of the bottom surface portion 45 of the detergent storage container 43, the detergent is formed. If the amount is large, the detergent may leak from the discharge port 46. On the other hand, in the above configuration, since the inclined surface portion 51 is provided so as to be inclined toward the opposite side of the discharge port 46, the detergent is discharged by the inclined surface portion 51 as shown in FIG. It is possible to prevent approaching 46 to some extent. That is, since there is only a relatively narrow gap between the lower end of the inclined surface portion 51 and the bottom surface portion 45, in the detergent, the above-mentioned gap acts as a resistance and the discharge port 46.
Becomes difficult to approach. Therefore, even if the amount of the detergent to be added is large, the detergent can be almost prevented from leaking from the discharge port 46.

Particularly, in the above embodiment, the detergent storage container 43
The opening edge portion 47 of the discharge port 46 in the bottom surface portion 45 is an inclined surface that is inclined so as to be higher toward the discharge port 46, and the height of the opening edge portion 47 is higher than the lowest point portion of the bottom surface portion 45. Since it is also configured to be higher, it is possible to more reliably prevent the detergent from leaking from the discharge port 46. Further, since both end portions 47a, which are a part of the opening edge portion 47, are configured to be lowered, it is possible to discharge all the water from this lower portion and reliably prevent the water from remaining in the detergent storage container 43. it can. In this case, the detergent may leak from the lower end portions 47a of the opening edge portion 47, but the user usually puts the detergent into the detergent storage container 43 at a substantially central portion with a measuring spoon or the like. Therefore, the detergent does not leak from the detergent storage container 43 unless the detergent storage container 43 (detergent storage unit 26) is tilted at a considerable angle.

Further, since the lower end portion 48a of the side wall portion 48 of the detergent storage container 43 on the discharge port 46 side is configured to extend below the position where the opening edge portion 47 is raised, the discharge is performed from the discharge port 46. The generated water is the lower end 48 a of the side wall 48.
After hitting, it will fall downward. This can prevent the water discharged from the discharge port 46 from jumping forward.

Further, in the case of the above-mentioned embodiment, since the handle member 49 in which the inclined surface portion 51 and the handle portion 50 are integrally formed is attached to the detergent storage container 43, the number of parts can be reduced and the configuration is simplified. be able to. Further, in the handle member 49 which is an integrated body of the inclined surface portion 51 and the handle portion 50,
A pair of wall portions 52 are formed so as to form a fitting groove 54 that fits on the upper portion of the side wall portion 48 of the detergent storage container 43 on the discharge port 46 side,
Since 53 is provided, the inclined surface portion 51 and the handle portion 5 are provided.

At the time of mounting to 3, the mounting can be performed only by fitting the fitting groove 54 between the pair of wall portions 52 and 53 to the side wall portion 48, and the assemblability can be improved.

In the case of this construction, the pair of wall parts 5
An engaging hole 53 a is provided as an engaging portion in one of the wall portions 53 of the reference numerals 2, 53, and the side wall portion 48 of the detergent storage container 43.
Since the engaging claw 48b is provided as the engaged portion so as to engage with the engaging hole 53a, the assembling work for attaching the handle member 49 to the detergent storage container 43 is further simplified and its attaching strength is increased. Will be sufficient. The wall 53
An engaging claw is provided as an engaging portion on the detergent storage container 4
An engaging hole may be provided as the engaged portion that engages with the engaging claw on the side wall portion 48 of the third embodiment.

The engagement hole 53a is formed in the pair of wall portions 5
Since it is configured to be provided on the inner wall portion 53 of the reference numerals 2, 53, the user does not see the engagement hole 53a and the engagement claw 48b, so that the appearance can be improved. Further, since the front wall portion 52 of the pair of wall portions 52, 53 is configured to be flush with the front surface of the side wall portion 48 of the detergent storage container 43 on the discharge port 46 side (front side), The wall portion 52 does not project from the front surface of the side wall portion 48 of the detergent storage container 43, and it is possible to prevent the user's finger or the like from being caught on the front wall portion 52.

On the other hand, in the above embodiment, the detergent storage container 43
Since the gaps 55 and 56 are provided in the rear portion and the lower portion between the guide surface portion 32 and the guide surface portion 32, and the water injection port 37 for injecting water into the gaps 55 and 56 is provided in the first water injection member 24, the detergent is used. Ensure that the water and the detergent discharged from the discharge port 46 of the storage container 43 or the upper surface opening of the detergent storage container 43 to the guide surface portion 32 are swept toward the rotary tank 4 by the water poured into the gaps 55 and 56. You can
Therefore, it is possible to more reliably prevent the detergent from remaining on the guide surface portion 32.

Further, in the above embodiment, the first water injection member 2
Since the contact portion 24a of the tip end portion of No. 4 is brought into contact with the upper end portion of the inclined surface portion 51, the water injected from the water injection port 36 of the first water injection member 24 into the detergent storage container 43 is stored in the detergent storage container 43. Even if a phenomenon occurs in which the water overflows in the container 43 and tries to return to the upper side, the above-mentioned water overflows to the upper side of the first water injection member 24 by the contact portion 24a of the first water injection member 24 and the inclined surface portion 51. The contact with the upper end can be surely prevented.

In the above embodiment, the opening edge portion 47 of the discharge port 46 in the bottom surface portion 45 of the detergent storage container 43 is an inclined surface which is inclined toward the discharge port 46 so as to be higher. However, the opening edge portion may be a horizontal surface or an inclined surface having a gentler angle than the other bottom surface portions. Even with this structure, it is possible to obtain substantially the same operational effects as those of the above embodiment.

[0051]

As is apparent from the above description, the present invention provides an inclined surface portion below the water injection port of the water injection member so as to be lowered toward the side opposite to the discharge port, and the detergent storage container. Since the bottom part of the is inclined so as to be lower toward the discharge port, the water injected from the water injection port will not be scattered in the detergent storage container, and the water causes the detergent in the detergent storage container to be washed. Is sufficiently agitated, and even when the amount of detergent is small or the force of water is strong, the detergent is sufficiently agitated in the detergent storage container and the detergent is not stored in the detergent storage container or the guide member. It has an excellent effect of not remaining. Further, in the above configuration, since the inclined surface portion is provided so as to be inclined toward the side opposite to the discharge port, the inclined surface portion can prevent the detergent from approaching the discharge port as much as possible, and the amount of the detergent is large. However, it is possible to prevent the detergent from leaking from the outlet.

Further, in the case of the above construction, since the inclined surface portion is formed integrally with the handle portion attached to the front portion of the detergent storage container, the number of parts can be reduced and the construction can be simplified. Further, the opening edge portion of the discharge port in the bottom surface portion of the detergent storage container is a horizontal surface, an inclined surface having a gentler angle than other portions, or an inclined surface inclined so as to be higher toward the discharge port, and Since the height of the edge portion is set to be higher than the lowest point portion of the bottom surface portion, it is possible to more reliably prevent the detergent from leaking from the discharge port.

Furthermore, since a part of the opening edge is made low, all the water can be discharged from this low part, so that it is possible to prevent water from remaining in the detergent storage container. Further, since the lower end portion of the side wall portion on the discharge port side of the detergent storage container is configured to extend downward from the position where the opening edge portion is higher, the water discharged from the discharge port is lower than the lower end portion of the side wall part. After hitting, it will fall downward. As a result, it is possible to reliably prevent the water discharged from the discharge port from jumping forward.

On the other hand, in the integrated body of the inclined surface portion and the handle portion,
Since the pair of wall portions is provided so as to form the fitting groove that fits on the upper portion of the side wall portion on the discharge port side of the detergent storage container, the integrated product of the inclined surface portion and the handle portion is attached to the detergent storage container. At this time, the fitting can be performed only by fitting the fitting grooves of the pair of wall portions to the side wall portions, and the assemblability can be improved. Further, in this case, the engaging portion is provided on at least one of the pair of wall portions, and the engaged portion is provided on the side wall portion on the discharge port side of the detergent storage container so as to engage with the engaging portion. Then, the assembling work becomes easier.

If the engaging portion is provided on the inner wall portion of the pair of wall portions, the outer appearance is improved because the engaging portion is not visible. Further, if the front wall portion of the pair of wall portions is provided so as to be flush with the front surface of the side wall portion on the discharge port side of the detergent storage container, or to be positioned rearward of the front surface, It is possible to prevent the front wall portion from protruding from the front surface of the wall portion of the detergent storage container, and prevent the user's finger or the like from being caught on the front wall portion.

On the other hand, when a gap is provided in the rear portion and the lower portion between the detergent storage container and the guide member, and a water injection port for injecting water into the gap is provided in the water injection member, the detergent storage container is discharged to the guide member. The discharged water and detergent can be reliably swept toward the washing tub by the water poured into the gap, and the detergent can be prevented from remaining on the guide member. Further, when the tip of the water injection member is brought into contact with the upper end of the inclined surface portion, the water injected from the water injection port of the water injection member into the detergent storage container overflows in the detergent storage container and tries to return upward. When the phenomenon occurs, the tip of the water injection member is in contact with the upper end of the inclined surface, so that the water can be reliably prevented from overflowing to the upper side of the water injection member.
