2 is a perspective view showing a variable detergent box of a washing machine according to an embodiment of the present invention, Figure 3 is an exploded perspective view showing a detergent box of a washing machine according to an embodiment of the present invention, Figure 4 is Detergent box of the washing machine according to an embodiment is a cross-sectional view, Figure 5 is a perspective view showing a variable payment of the detergent box of the washing machine according to an embodiment of the present invention.

2 to 5, a washing machine having a variable detergent box according to an embodiment of the present invention is provided in a water supply pipe 5a (see FIG. 1), and a case having an accommodating part 70 in which detergent is stored. 50 and a variable delivery part 80 which is detachably provided in the housing part 70 to receive the liquid detergent.

Thus, when the variable payment unit 80 is installed in the accommodating part 70, since the liquid detergent is freshly stored in the detergent box, the liquid detergent can be supplied accurately at the moment of starting the washing operation such as pre-washing or main washing.

Here, the accommodating part 70 is supplied with a first accommodating part 72 in which detergent for preliminary washing is stored, a second accommodating part 74 in which detergent for main laundry is stored, and after the washing operation is completed. Includes a third housing portion 76 in which the fabric softener is fresh.

The variable payment part 80 is preferably installed in the second storage part 74 in which the detergent for washing is stored, and the reason thereof is as follows.

The ordinary user opens the detergent container before starting the washing operation, puts the detergent in the first storage part 72 and the second storage part 74, and inserts the fabric softener in the third storage part 76 and then removes the detergent box. Since the washing operation is started by closing, the detergent is put into the second storage portion 74 before the pre-washing and the main washing.

Since the preliminary washing proceeds immediately after the washing operation is started, the liquid detergent dehydrated in the first storage unit 72 may be supplied with the liquid detergent to the tub (see FIG. 1) before the preliminary washing starts.

The second storage part 74 because the liquid detergent contained in the second storage part 74 must be supplied to the tub 2 before the washing machine starts after the fresh water is washed in the second storage part 74 during the preliminary washing. The variable payment part 80 installed at the c) suppresses the supply of the liquid detergent to the tub 2 along the water supply pipe 5a.

This makes it possible to prevent the detergent more than necessary from being supplied to the tub 2 by the liquid detergent supplied from the second storage portion 74 during the preliminary washing, and the second water immediately before the main washing is performed. Since the liquid detergent that has been dehydrated in the payment 74 and the variable payment 80 is supplied to the tub 2, the amount of detergent required for the present washing is not insufficient.

As described above, the liquid detergent contained in the variable payment part 80 is prevented from flowing to the tub 2 side along the water supply pipe 5a, and the variable payment part 80 is provided when the wash water is supplied to the variable payment part 80. The siphon tube 82 is provided in the variable payment part 80 so that the liquid detergent or the wash water does not remain on the bottom.

The siphon tube 82 includes a tube 82a protruding from the bottom surface of the variable payment part 80, and a stopper 82b covered on an upper end of the tube 82a, and the tube 82a includes a second storage part ( It is arranged to communicate with the discharge passage (74a) provided in 74.

In addition, the bottom surface 84 of the variable soldering portion 80 is formed of an inclined surface inclined in the direction of the tube 82a, and a groove portion 86 is formed in the circumference of the tube 82a to be concave downward.

When the wash water is supplied to the variable payment part 80 by the structural features as described above, both the fresh liquid detergent and the wash water do not remain in the variable payment part 80 but are moved to the tub 2 side along the water supply pipe 5a. .

Since the siphon tube 82 as described above is similar to the operation principle of the siphon tube applied to a conventional washing machine, the rationale or engineering analysis in which the above operation occurs will be omitted.

In addition, the detergent box according to an embodiment of the present invention further includes a detachable part 90 provided in the accommodating part 70 and the variable payment part 80. When coupled, the variable payment unit 80 is prevented from being separated from the housing unit 70 by the detachable unit 90.

The detachable part 90 includes a catching protrusion 92 provided in the accommodating part 70, and a hook portion 94 provided in the variable payment part 80 corresponding to the catching protrusion 92.

The ring portion 94 is a plurality of groove portions formed on the edge of the variable payment portion 80, the locking projection 92 is fitted to the ring portion 94, so the variable payment portion 80 is the storage portion 70 It is possible to prevent the separation from.

Here, the sizes of the locking projections 92 and the ring 94 may be varied, and the variable protrusions are formed to be relatively large formed on one side of the plurality of locking projections 92 and the ring 94 The effect of improving the fastening force between the 80 and the receiving portion 70 is shown.

Looking at the operation of the washing machine having a variable detergent box according to the present invention configured as described above are as follows.

First, after opening the door to store the laundry inside the drum (see Fig. 1), the detergent box is opened, the detergent is put into the first storage unit 72 and the second storage unit 74, and the third storage unit ( 76) Close the detergent compartment with the fabric softener.

In this case, when the detergent used is a liquid detergent, the variable payment part 80 is inserted into the second storage part 74, and the second water inside the ring part 94 formed at the edge of the variable payment part 80. As the locking projection 92 of the payment 74 is forcibly fitted, the variable payment unit 80 is installed.

When the washing operation is started and the preliminary washing proceeds, the washing water flowing along the water supply pipe 5a is supplied with the liquid detergent into the tub 2 while passing through the first storage unit 72.

After the preliminary washing is finished, the washing water supplied to the detergent along the water supply pipe 5a is supplied to the second storage portion 74 and supplied to the variable payment portion 80.

When the water level of the variable payment unit 80 overflows due to the wash water supplied to the variable payment unit 80, the liquid detergent and the wash water which were freshly immersed in the variable payment unit 80 by the action of the siphon tube 82 are supplied to the water supply pipe 5a. Is discharged to the tub 2 side.

As a result, when the preliminary washing proceeds, the liquid detergent supplied to the tub 2 can be prevented from being supplied to the second storage part 74 and the variable payment part 80.

Of course, when the powder detergent is used, the variable payment unit 80 may be used separately from the second storage unit 74.

In addition, the variable payment unit 80 may be provided in the first storage unit 72 and the third storage unit 76.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and various modifications and equivalent other embodiments are possible to those skilled in the art. Will understand.

In addition, although the detergent box of the drum washing machine has been described as an example, this is merely exemplary, and the variable detergent box of the present invention may be used in a washing machine other than the drum washing machine.

Therefore, the true technical protection scope of the present invention will be defined by the claims below.
