DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent dissolving apparatus for a washing machine, and more particularly to a detergent dissolving apparatus provided with a detergent dissolving filter having a new structure for storing detergent.

[0002]

2. Description of the Related Art Generally, when washing is performed using a washing machine, a detergent used remains on the laundry. To remove the residual detergent, several rinses, for example, four rinses, had to be performed. Therefore, in order to solve this problem, there has been a demand for a detergent dissolving apparatus which develops a detergent having good solubility or which is dissolved in advance by mechanical force to minimize the residual detergent in the laundry. Was.

In response, a detergent dissolving apparatus having a mechanical force for forcibly dissolving the detergent has been developed. The device dissolves detergent to a considerable level, enhances activity,
Since it penetrates evenly between the fibers, it not only reduces the amount of electricity, but also reduces the amount of water used, as well as improving the washing power and reducing the number of rinses.

[0004] Further, by reducing the amount of the detergent itself, there is an advantage of environmental protection.

[0005] A typical detergent dissolution apparatus is illustrated in FIG. In the figure, the detergent dissolving device is configured so that the power of the water jet injected from the water supply nozzle is doubled so as to separate the detergent particles and obtain the physical flow energy required for dissolution.

That is, the detergent dissolving device is composed of a rectangular parallelepiped outer body 1 and an inner body 2 housed inside the outer body 1 so as to be slidable right and left. Internal fuselage 2
, A filter 3 capable of containing a detergent therein is fixed in position. A water supply inlet 4 into which water is supplied is formed in the upper surface of the outer body 1 in the figure. A water supply connection pipe 6 is connected to the water supply inlet 4, and a water supply guide pipe 7 for guiding the supply water is provided between them.

The water supply guide pipe 7 is an acceleration pipe tapered from the upper part to the lower part in the figure for accelerating water supply, or an acceleration pipe 5 is installed in the inside thereof, and is provided between the acceleration pipe 5 and the water supply guide pipe 7. Are formed with air holes 9 for pressurizing the supplied water to increase the detergent dissolving efficiency. A net-like water backflow prevention plate 8 is arranged between the water supply guide pipe 7 and the water supply inlet 4 to prevent backflow of supplied water.

Therefore, as shown in FIG. 8 showing a side cross section of the detergent dissolving apparatus, a water supply guide pipe 7 having an acceleration pipe 5 and an air hole 9 is connected to the outer body 1. You. The inner body 2 is inserted into the outer body 1 when the funnel or the conical filter 3 is settled therein.

Since the apparatus is assembled in this manner, the apparatus reduces the cross-sectional area on the outlet side of the accelerating pipe 5, increases the flow rate, and at the same time allows air to flow through the air holes 9, thereby further accelerating the flow rate. To form strong water currents.
The water stream smashes the detergent contained in the upper surface of the filter 3, passes through the filter 3, and causes the detergent to dissolve while causing a vortex in the inner body 2.

[0010]

[SUMMARY OF THE INVENTION] However, the detergent dissolving device, wash water exiting the accelerating pipe 5, through the bottom of the detergent and the filter 3 by injection force of the apparatus, the water flow force F ₁ is area Only by applying fluidity to the detergent in A, a lump of detergent is separated, and dissolution is achieved only by circulating detergent particles in the filter 3.

If the feedwater pressure is low (about 0.8 kgf
/ Cm ³ or less), the spraying force exerts a weak force on the region A, causing a problem that the detergent mass remains on the upper edge of the filter as it is.

At the beginning of the water supply, the washing water becomes the same as the water flow G, and the detergent particles pass over the filter 3 and accumulate on the detergent cylinder corner C. The water flow force F ₂ formed by the streamlined water flow is: The inability to impart a change in flow to the detergent accumulated in the corner portion C causes the detergent to remain.

In addition, at the initial stage of water supply and at high water pressure, the undissolved detergent particles instantly close the filter, so that the output amount is small compared to the input injection amount. Alternatively, the lump) overflows and comes out of the detergent cylinder in the direction of the water flow force F.

In order to prevent such a problem, the overflow space, that is, the gap G must be minimized. However, as the gap G is reduced, the washing water flows back into the air holes 9.

Although this can be prevented by a check valve or the like, the method of preventing the wash water from flowing back to the cold water connection pipe (toward the hot water connection pipe at the time of cold water supply) at the time of hot water supply is as follows. Quite difficult.

[0016] Such a problem is continued until it is penetrated because the jetting power of the acceleration pipe at low water pressure cannot pass through the detergent in the filter. Furthermore, because of the high soap content, a sticky detergent is more severe.

As described above, the existing detergent dissolving apparatus has a limit in the performance and quality improvement due to the residual of the detergent at the time of low water pressure, the discharge of many dissolved detergent particles, the correlation of backflow, inconsistency, and the like. There is a problem that the amount of water supply is small and the entire washing time is long due to the acceleration pipe for increasing the flow velocity or the reduction of the nozzle cross-sectional area.

It would be extremely desirable to solve any one or more of these problems with a simple structure. For this,
SUMMARY OF THE INVENTION It is a main object of the present invention to provide a detergent dissolving apparatus in which a detergent container having an improved filter portion is provided so that the detergent is not discharged to the outside of the detergent container without being dissolved.

It is another object of the present invention to provide a detergent dissolving apparatus in which the swirling force of the washing water is increased in the detergent container to dissolve the detergent promptly and discharge it.

Still another object of the present invention is to provide a detergent container which is supported by an external support, and which has an inner body for accommodating the detergent container and an inclination angle of a bottom surface of the outer body such that the inner body is slidingly inserted. Another object of the present invention is to provide a detergent dissolving apparatus having a compact structure.
