Description

Apparatus suppling detergent in the washing machine}

The present invention relates to a washing machine, and more particularly, to a detergent input device of the washing machine to facilitate the mixed washing water discharge.

In general, a washing machine is a device that separates foreign matters from laundry by forcibly flowing the wash water by friction between water and laundry, emulsification of the detergent, and impact on the laundry.

Such a washing machine previously contains a detergent, a fabric softener, and / or an additive (hereinafter, abbreviated as "detergent") in a detergent input device. In this state, when the washing machine is operated, detergent or the like is introduced in a process of sequentially or selectively performing washing, rinsing, and dehydration strokes.

Hereinafter, a detergent injector of a general washing machine will be described with reference to FIGS. 1 to 4.

Referring to FIG. 1, a top cover 1 is installed at an upper portion of the washing machine, a detergent input device is installed at the top cover 1, and a water supply device is installed at a rear side of the detergent input device.

The water supply device comprises a plurality of solenoids (3) for supplying and cutting off the wash water, and a water supply pipe (4) connected to the solenoid at all times and supplying the wash water to the detergent input device and the housing.

A housing 10 is installed in the top cover 1, and a detergent injecting device is inserted into the housing 10 so as to be withdrawn. The bottom surface of the housing 10 is formed to be inclined.

The water supply pipes 4 are disposed in the housing 10, respectively, and supply washing water to the detergent injecting device and the housing bottom as the user selects a predetermined stroke.

For example, three water pipes are connected to the upper portion of the housing 10 to supply wash water to each chamber of the detergent dispensing device. Accordingly, the wash water mixed with the detergent or the like contained in the detergent input device (hereinafter, abbreviated as "mixed wash water") is discharged to the bottom of the housing and then supplied to the washing tank.

In addition, one water supply pipe is connected to the housing 10 so as to be disposed at the rear side of the detergent injector so that the wash water supplied to the bottom of the housing is supplied directly to the bottom of the housing without passing through the detergent injector.

This detergent dosing device will be described in more detail.

Referring to FIG. 2, the detergent dispensing apparatus includes a shower tray 20 (see FIG. 1), a detergent box 30, and siphon covers 41, 42, and 43.

The shower tray 20 is installed above the housing 10, the detergent box 30 is installed below the shower tray 20, and the siphon covers 41, 42, and 43 are detergent boxes. It is installed to cover the upper portion of the (30).

The shower tray 20 includes a detergent shower unit 21 and an additive shower unit 22 as shown in FIG. 1. The detergent shower unit 21 and the additive shower unit 22 are provided with a plurality of through-holes so that the washing water supplied by the water supply device falls on the detergent box 30.

In addition, the detergent box 30 is installed in the housing 10 to be withdrawn. At least two or more chambers are formed in the detergent box 30 to accommodate detergents.

More specifically, the detergent box 30 has a detergent chamber 31 is formed in the center, the additive chamber 32 and the softener chamber 33 is formed on both sides of the detergent chamber. In this case, the detergent chamber 31 is disposed under the detergent shower unit 21, and the additive chamber 32 is disposed under the additive shower unit 22. Here, of course, it can be manufactured by changing the position of each chamber or the number of chambers.

In the detergent chamber 31, a box-type detergent container 36 having an open upper surface is separately seated to form a space for storing detergent.

The detergent container 36 is seated in the detergent chamber 31 when the liquid detergent is added, and separated from the detergent chamber when the powder detergent is added. Accordingly, the detergent dispensing apparatus may selectively use a liquid detergent and a powder detergent.

The rear end of the detergent container 36, the additive chamber 32 and the softener chamber 33 is formed with stepped portions 37 so that the washing water overflows to the rear side of the detergent box.

Meanwhile, the detergent siphon cover 41 is installed to cover the open upper surface of the detergent container 36. In addition, the additive siphon cover 42 and the softener siphon cover 43 are provided to cover the open upper surfaces of the additive chamber 32 and the softener chamber 33.

Inner siphon columns 34 are formed on the bottom surfaces of the detergent container 36, the additive chamber 32, and the softener chamber 33 to protrude upward. A siphon hole 35 (refer to FIGS. 2 and 3) is formed in the center of the inner siphon column 34 along the longitudinal direction of the inner siphon column.

In addition, outer siphon columns 44 are formed on the lower surfaces of the detergent siphon cover 41, the additive siphon cover 42, and the softening siphon cover 43 so as to protrude downward. A hollow is formed along the longitudinal direction of the outer siphon column at the center of the outer siphon column 44.

At this time, a plurality of siphon ribs 36 are formed on the outer circumferential surface of the inner siphon column 34 so as to protrude radially. Accordingly, the outer siphon column 44 is inserted into the inner siphon column 34 so as to maintain a predetermined distance (C). At this time, a space portion (not shown) of a predetermined height is formed above the inner siphon column 34.

Referring to FIG. 3, a space keeping rib 38 protrudes from the bottom surface of the additive chamber 32 and the softener chamber 33. The gap retaining rib 38 uniformly spaces the gap between the lower surface of the housing 10 and the lower surface of each chamber 31, 32, 33 when the detergent box 30 is deformed. Therefore, the mixed washing water in each chamber is smoothly discharged to the bottom surface of the housing by the siphon phenomenon.

Referring to the operation of the detergent dosing device configured as described above are as follows.

When the user selects a predetermined button through the operation unit, the wash water is selectively discharged to the housing bottom or / and the shower tray 20 through the water supply pipe 4 of each wash water supply unit.

When wash water is supplied to the predetermined chamber, detergent, softener or additives is mixed with the wash water. At this time, when the wash water is filled more than the step portion 37 (see Fig. 2) of the predetermined chamber, the wash water of the predetermined chamber is overflowed to the step portion 37 formed on the rear side of the detergent box 30. It is discharged to the bottom surface of the housing 10 through.

At this time, once the mixed washing water is discharged through the siphon hole 35 of the inner siphon column 34, the mixed washing water contained in the chamber continues until the mixed washing water is almost disappeared by the siphon phenomenon. Is discharged to the bottom surface of the housing 10.

On the other hand, when the wash water is supplied to the rear side of the detergent box 30, the wash water is discharged directly to the lower surface of the housing 10 without entering the detergent box, the discharged wash water is the lower surface of the detergent box 30 It is discharged into the washing tank through.

However, the detergent input device of the conventional washing machine has the following effects.

First, as the user selects a predetermined stroke, water flows in various directions on the bottom surface of the housing by washing water overflowed from the chamber and / or wash water discharged directly to the housing bottom. Is formed.

This water flow affects the siphon phenomenon while passing through the lower part of the siphon hole. That is, the water flow causes the mixed wash water to cause a capillary phenomenon in the siphon hole, and the discharge of the mixed wash water is stopped or the discharge efficiency is reduced by the capillary phenomenon.

Second, since the water supply device supplies the washing water in the predetermined chamber while the solenoid is turned on / off at predetermined intervals, the capillary phenomenon is caused in the siphon hole by the washing water remaining in the lower part of the siphon hole. Is generated. Accordingly, the siphon hole has a problem that water clogging occurs.

Third, even if the water flow of the washing water is formed in any direction, it always affects the siphon hole of the detergent chamber located in the center as shown in FIG. Accordingly, a problem of reducing the siphon phenomenon in the detergent chamber occurs.

In order to solve the above-mentioned problems, an object of the present invention is to provide a detergent injection device of the washing machine so that the siphon phenomenon occurs more smoothly in the detergent input device, and the mixed washing water is discharged without remaining.

In order to achieve the above object, the present invention is installed in the housing of the top cover retractable, at least two or more chambers are formed to put detergent, etc., wherein each of the inner siphon column is formed to protrude upward A detergent box formed at a lower surface of each chamber to form a guide rib in contact with a bottom surface of the housing near a siphon hole of an inner siphon column; And a siphon cover seated in each chamber so as to cover the upper surface of each chamber, and each cover having a siphon cover protruding downward from the inner siphon column so as to maintain a predetermined interval. Provide a detergent dispensing device for the washing machine.

At this time, the guide rib is preferably opened in the washing tank-side predetermined portion to prevent the washing water flowing in the lower surface of the housing to flow into the lower portion of the siphon hole.

Hereinafter, an embodiment of a detergent input device of a washing machine according to the present invention will be described with reference to Figures 2, 5 to 8.

Figure 5 is a rear view showing the back structure of the detergent box according to the invention, Figure 6a is an enlarged perspective view showing the shape of the guide rib formed on the lower surface of the detergent chamber of Figure 5, Figure 6b is a softener of the detergent chamber of Figure 5 7 is an enlarged perspective view showing the shape of the guide rib formed on the lower surface of the chamber, FIG. 7 is a state diagram illustrating a flow state in which the washing water is discharged to the bottom of the housing by a siphon phenomenon in the detergent input device of FIG. 5, and FIG. 8 is FIG. It is a state figure shown in order to demonstrate the flow state of the wash water which flows through the back of the detergent box.

5 and 7, the detergent input device includes a detergent box 60 and a siphon cover 70 (see FIG. 7).

The detergent box 60 is installed to be withdrawn in the housing installed in the top cover 1, and at least two or more chambers are formed to accommodate detergents.

An inner siphon column 64 protrudes upward from the bottom surface of each chamber.

The siphon cover 70 is seated in each chamber to cover the upper surface of each chamber. On the lower surface of the siphon cover 70, the outer siphon column 71 (see FIG. 7) protrudes downward to be inserted into the corresponding inner siphon column 64 to maintain a predetermined interval.

In this case, guide ribs 66a and 66b protrude to a predetermined height H on the lower surface of each chamber near the siphon hole 65 of the inner siphon column 64 as shown in FIGS. 6A and 6B. The guide ribs 66a and 66b are installed to contact the bottom surface of the housing 50 as shown in FIG. 7.

The guide ribs 66a and 66b are preferably formed such that the washing tank-side predetermined part is opened. This is to prevent the washing water flowing into the bottom surface 51 of the housing 50 from flowing into the lower portion of the siphon hole 65.

The guide ribs 66a and 66b may be formed in a substantially arc shape to surround the siphon hole 65. The guide ribs 66a and 66b may be changed into various shapes in addition to the arc shape.

When the detergent injecting device has three chambers as an example will be described in more detail as follows.

Three chambers are installed in the detergent box 60 to contain detergent. That is, the detergent chamber 61 is installed at the center, and the softener chamber 62 and the additive chamber 63 are installed at both sides of the detergent chamber 61. Of course, the position of these chambers can be changed in various ways.

Guide ribs 66a and 66b are formed on the lower surfaces of the three chambers 61, 62 and 63, respectively, in which a predetermined portion of the washing tank side is opened. The guide ribs 66a and 66b protrude to a predetermined height H as shown in FIGS. 6A and 6B.

At this time, it is preferable that both ends of the guide rib 66a of the detergent chamber 61 located at the center extend a predetermined length to the washing tank side. This is to prevent the washing water from flowing into the lower portion of the siphon hole 65 even when the water flow direction of the washing water is changed by selectively operating the water supply device.

The guide rib 66a of the detergent chamber 61 is formed in a substantially "U" shape. In addition, the softener chamber 62 and the guide rib 66b of the additive chamber 63 which are located in the both sides of the said detergent chamber 61 are formed in substantially arc shape. The guide ribs 61, 62, and 63 may be formed in various ways in addition to the above-described shape.

The guide ribs 66a and 66b formed in the respective chambers are preferably formed to have a height of approximately 0.3-0.7 mm. This is because the interval between the bottom of the siphon hole 65 and the bottom surface 51 of the housing 10, 50 maintains the above-described spacing so that the siphon phenomenon can be smoothly generated in the siphon columns 64 and 71. Because you can.

The operation of the detergent injector of the present invention configured as described above will be described.

When the user selects a predetermined button through the operation unit, the wash water is selectively discharged to the housing bottom 51 and / or the shower tray 20 (see FIG. 1) through the respective wash water supply units.

When wash water is supplied to the predetermined chamber, detergent, softener or additives is mixed with the wash water. At this time, when the wash water is filled more than the step portion 68 (see Fig. 2) of the predetermined chamber, the wash water of the chamber is overflowed (through the step portion 68 formed on the rear side of the detergent box 60) It is discharged to the bottom surface 51 of the housing 50.

In this case, the wash water overflowed from the one side and / or both chambers flows to the washing tank side by the inclination of the housing bottom surface 51, and at this time, the washing water forms a stream of water that spreads toward the detergent chamber 61.

In addition, when the wash water is supplied to the rear side of the detergent box 60, the wash water flows between the bottom surface 51 of the housing and the lower surface of the detergent box 60 to form a water flow.

As the washing water is formed in various directions as shown by the arrow of FIG. 8, the washing water flowing to the guide ribs 66a and 66b is blocked by the guide ribs 66a and 66b to bypass the siphon hole 65. do.

In addition, the guide rib 66a of the detergent chamber 61 bypasses the siphon hole 65 regardless of whether the softeners located at both sides and the water flow formed at the center side in the additive chambers 62 and 63.

By the action of the guide ribs 66a and 66b, it is possible to prevent the washing water from flowing in the lower portion of the siphon hole 65 regardless of which water flow is formed.

Thus, once the mixed wash water begins to be discharged through the siphon hole 65 of the inner siphon column 64, the mixed wash water contained in the chamber is continued until the mixed wash water is almost eliminated by the siphon phenomenon. To be discharged to the bottom surface 51 of the housing.

As described above, the detergent input device according to the present invention has the following effects.

First, by preventing the flow of washing water to the lower portion of the siphon hole by the guide rib, there is an effect that can generate the siphon phenomenon more smoothly.

Second, since the wash water is prevented from flowing to the lower portion of the siphon hole, there is an effect that can prevent the capillary phenomenon from occurring in the siphon hole unlike the conventional.

Third, therefore, the mixed washing water can be easily discharged from the siphon column so that the mixed washing water remaining in each of the chambers is hardly present.
