Description

Detergent feeding device in drum-type washing machine

The present invention relates to a detergent input device of a washing machine, and more particularly, laundry performance by preventing the detergent from infiltrating into the fabric softener input area when the detergent is introduced into the main laundry detergent preserving area and the prewashing detergent input area of the detergent container. And it is to be able to improve the rinsing performance.

In general, the drum washing method is a method of washing by using a friction between the rotating drum and the laundry by receiving the driving force of the motor in a state in which detergent, washing water and laundry are put in the drum. Don't get tangled with each other, knocking and rubbing can have a laundry effect.

As shown in FIG. 1, the drum washing machine 1 includes a detergent container 1 containing detergent, and a functional operation unit 6 for selecting a function of a washing machine such as a washing course.

On the other hand, as shown in Figs. 2 to 4, the detergent container 1 is filled with a detergent washing area A for main washing and a preliminary washing detergent by a partition wall 10 (iii) formed so as to face each other. It is divided into three zones, the zone B and the fiber softener injection zone C located in the middle thereof.

In other words, the detergent is contained in each area and put into each washing course.

At this time, the handle 50 is attached to the front surface of the detergent container 1 so as to easily handle the detergent container 1.

However, the conventional detergent container 1 configured as described above has the main laundry detergent input area A, the prewashing detergent input area B, and the two laundry walls 10 facing each other as described above. Although it is divided into three zones of the fiber softener injection zone (C), the upper part of each zone is open, which causes the following problems.

That is, when the detergent is introduced into the main laundry detergent input area A or the prewashing detergent input area B of the detergent container 1, the detergent penetrates into the fiber softener input area C.

Accordingly, when the last rinse of the fabric softener is introduced, not only the fabric softener but also the detergent penetrating into the fiber softener input area C may be introduced into the tub, thereby reducing the rinsing performance.

In other words, while the purpose of performing the rinsing stroke is to reduce the concentration of the detergent remaining in the laundry, the rinsing stroke when the detergent penetrates into the fabric softener input area (C) while the detergent is introduced into the detergent container (1). The detergent is re-introduced into the tub, resulting in a thickening of the detergent again, resulting in a poor rinsing performance, which in turn lowers the reliability of the product.

The present invention is to solve the above problems, the detergent is introduced into the fabric softener input area (C) when the detergent in the detergent washing area (A) and pre-washing detergent input area (B) of the detergent container. It is an object of the present invention to provide a drum washing machine detergent injection device that can effectively prevent the phenomenon that the rinsing performance is reduced by preventing intrusion.

According to the present invention, an inner space of the main laundry detergent injection zone (A) and the pre-washing detergent injection zone (B) is provided by two partition walls 10 disposed to face each other, and a fiber softener injection zone exists between the areas. In (C), the detergent container (1) having a drain pipe 20 to siphon the rear of the fiber softener input area (C); At the upper end of the partition 10, a detergent intrusion preventing cover 3 for selectively shielding the remaining area except the upper part of the drain pipe 20 or the upper part of the drain pipe 20 in the fiber softener input area C moves along the partition wall. Possibly mounted.

In this case, as shown in FIG. 8, the slide protrusion 300 is bent inwardly at the front end of both flange portions 30 of the detergent intrusion preventing cover 3, and the detergent intrusion is formed at the outer upper end of the partition 10. The guide groove 100 in which the slide protrusion 300 of the detergent intrusion prevention cover 3 is positioned is formed so that the prevention cover 3 can slide along the longitudinal direction of the partition 10.

On the other hand, since the material of the detergent intrusion preventing cover 3 is resin, both flange portions 30 have elasticity of a predetermined size, and thus the detergent intrusion preventing cover 3 is located at the upper end of the partition wall 10. Although it may be assembled by pressing, it is most preferred that the cover 3 is pushed forward and assembled in a state where the slide projection 300 on the front side of the cover is aligned with the guide groove 100 on the rear side of the partition 10.

In addition, as shown in Figure 9, the hook piece 101 is protrudingly formed on one side of the upper end of the partition 10 in front, the upper side of the drain pipe 20 after the detergent is injected on one side of the detergent intrusion preventing cover (3). The hook groove 301 is formed to move to the hook piece 101 of the partition 10 when the detergent intrusion preventing cover 3 is moved forward of the detergent container 1 so that the cover is exposed, and the hook piece 101 is hooked. The groove 301 is configured to prevent movement of the detergent intrusion preventing cover 3 in the partition wall longitudinal direction.

In this case, the hook piece 101 formed on the partition 10 may be formed only at one end of the partition 10, and may be formed at both upper ends of the partition 10 to increase reliability. The cover 3 is also provided with a hook groove 301 in accordance with the number of hook pieces 101.

The assembly process of the detergent intrusion prevention cover for the detergent container of the present invention configured as described above is as follows.

First, when assembling the detergent intrusion prevention cover (3) in the detergent container (1), the detergent intrusion prevention cover (3) is placed on top of the fabric softener input area (C) of the detergent container (1), and then the detergent intrusion prevention cover (3 By pressing), the slide protrusion 300 provided at the tip of the flange portion 30 of the cover is located in the guide groove 100 outside the partition 10 to complete the assembly.

At this time, the slide projection 300 of the detergent intrusion preventing cover 3 is snap-fit to the guide groove 100 of the partition wall 10 by the elastic deformation of the flange portion 30 generated during the press-fit.

On the other hand, when assembling the detergent intrusion preventing cover 3 in the detergent container 1 as described above, the assembly of the detergent intrusion preventing cover 3 with respect to the partition 10 is a hook piece of the partition 10 as shown in FIG. After being made at the position out of 101, the hook intrusion prevention cover 3 is pushed forward to allow the hook groove 301 and the hook piece 101 of the partition wall 10 to be joined together.

Accordingly, the detergent intrusion preventing cover 3 is caught by the hook piece 101 so as not to leave the position even if vibration occurs during washing.

When assembling the detergent intrusion preventing cover 3 into the detergent container 1 as described above, the detergent intrusion preventing cover 3 is assembled at a position completely out of the hook piece 101 of the partition 10 as shown in FIG. 6. This is advantageous, because when the detergent intrusion prevention cover 3 is assembled at a position not to escape the hook piece 101 of the partition 10, the hook piece (due to the height h) due to the height of the hook piece 101 ( This is because the detergent intrusion prevention cover 3 is lifted up at a portion where 101 is located so that a part of the slide protrusion 300 does not enter the guide groove 100.

The action of the detergent container 1 of the present invention assembled as described above is as follows.

First, when the detergent is put into the detergent container 1 before the washing process, the user pulls out the detergent container 1 stored in the detergent container 1 storage part of the front panel unit by a predetermined distance, and then puts the detergent for washing the main container of the detergent container 1 into the container. Before the detergent is introduced into the region A or the detergent washing region B for pre-washing, it is checked whether the detergent intrusion preventing cover 3 is positioned as shown in Fig. 7A.

That is, when the detergent is injected, the detergent intrusion preventing cover 3 should be positioned in front of the detergent container 1 so that the drain pipe 20 of the fabric softener input area C is exposed.

In this state, the detergent may be introduced into the desired region of the main laundry detergent input area (A) and the prewashing detergent input area (B).

At this time, the detergent may infiltrate into the fabric softener input region (C), but because the detergent intrusion preventing cover (3) covers the upper portion of the fabric softener input region (C), the fabric softener input region of the detergent ( No intrusion into C) occurs.

On the other hand, if you want to inject the fabric softener into the fabric softener input area (C) following the detergent input, push the detergent intrusion preventing cover (3) to the rear of the detergent container (1) of the fabric softener input area (C) as shown in Figure 7b Open the front and then add the fabric softener to the open area.

In this way, after the detergent and the fabric softener has been added, the detergent intrusion preventing cover 3 is placed in front of the detergent container 1 as shown in FIG. 7A to proceed with washing. 20) Only the top is exposed.

Accordingly, during the washing stroke, the portion except the drain pipe 20 of the fabric softener input region C is always covered by the detergent intrusion preventing cover 3.

On the other hand, during the last rinsing of the rinsing stroke, water is supplied from the water dispenser (not shown) provided in the upper part of the detergent container 1 through the upper region of the drain pipe 20 in a shower manner, and thus the fiber softener input area (C) The fabric softener and washing water already added to the mixture is mixed, and when the mixed liquid reaches a predetermined level, the mixed liquid is released into the gap between the drain pipe 20 and the cap 40 by the siphon function.

In this way, the mixed liquid of the fiber softener and the wash water, which has escaped into the gap between the drain pipe 20 and the cap 40 by the siphon function, flows into the tub to give the fiber softening effect.

As described above, the present invention is a drum washing machine, the detergent installed in the detergent input area when the detergent detergent input area (A) and the pre-washing detergent input area (B) of the detergent container 1 in the detergent washing area The intrusion prevention cover 3 prevents the detergent from entering the fabric softener input area C.

Accordingly, the present invention can effectively prevent the phenomenon that the rinsing performance is lowered due to the detergent intrusion, since only the fabric softener is introduced into the tub during the final rinsing of the rinsing stroke, thereby improving the consumer's confidence in the product. I can do it.
