Description

Detergent supply device for drum washing machine {device for providing detergent in washing machine}

The present invention relates to a detergent supply apparatus for a drum washing machine, and more particularly, to a detergent supply apparatus for a drum washing machine which can automatically supply various detergents into the washing space under the control of a controller.

In general, the drum washing machine is installed in such a way that the outer circumferential surface of the cylindrical washing drum is positioned in the vertical direction, and thus the washing machine is capable of sucking the laundry by using a drop generated when the washing drum rotates.

The drum washing machine includes a main body forming a large appearance, a tub installed inside the main body and a washing drum filled with washing water, and a washing drum rotatably installed inside the tub and having a plurality of dehydration holes formed on a wall thereof.

In addition, a detergent supply device is installed on the tub to dissolve the detergent using the wash water supplied from the external water supply to the inside of the washing drum, and supply the wash water mixed therewith to the inside of the washing drum. According to the control of the control unit according to the various washing processes such as pre-washing, main washing, rinsing washing, cloth washing, dehydration, etc. are automatically performed, and detergents or fabric softeners necessary for each washing process are supplied to the inside of the washing tank. It is supposed to be.

1 is a perspective view showing a state in which a detergent container of a detergent supply apparatus installed in a general drum washing machine is drawn out, and FIG. 2 is a longitudinal sectional view schematically showing the structure of the detergent supply apparatus illustrated in FIG. 1, with reference to the drawings. The detergent supply unit of the washing machine is described as follows.

The detergent supply device of a general drum washing machine includes a detergent container housing (30) coupled to an upper side of the front side of the main body (10) of the drum washing machine, and a receiving groove for accommodating detergent so that the detergent container housing (30) can be withdrawn. The detergent container 40 is installed, and the water dispenser 20 for supplying the wash water to the detergent container (40).

When using the washing machine by the above-described configuration, as shown in Figure 1, the user withdraws a portion of the detergent container 40 to the front side of the main body 10 of the drum washing machine, each detergent separated in the detergent container 40 After the detergent and the fabric softener is put into the accommodating part, the detergent container 40 is pushed into the detergent container housing 30 to operate the washing machine.

When the washing machine is operated, the water supply valve 11 is opened as the washing process proceeds under the control of the control unit, and the washing water is supplied to the drum washing machine, and the washing water supplied to the drum washing machine is connected to the water supply dispenser through the connection hose. 20 is supplied to the water dispenser 20, the wash water is introduced into the detergent container 40 located on the lower side and mixed with the detergent or fabric softener and the like, the tub 50 through the water supply hose 12 ) Is supplied inward.

On the other hand, the detergent container 40 of the above-described detergent supply device is a detergent container and the fabric softener is dissolved by the wash water supplied to the inside during the washing process, the tub 50 is provided in the structure is supplied to the detergent container 40 Residual detergent is generated on the inside, and this process is repeated, the cleaning operation is required to remove the residual detergent residues for a certain period of time due to the residual detergent remaining in the detergent container 40.

However, the detergent container 40 has a structure that can be withdrawn only a portion of the predetermined width toward the front of the main body 10, the user is left because it is made of a structure that is not completely separated from the detergent container housing 30 There was a very troublesome problem in cleaning for removing the residue of the detergent, and after the user withdraws the detergent container 40 to the front of the main body 10 and puts a detergent or fabric softener into the inside thereof, the detergent container 40 is a detergent container. In the process of pushing into the housing 30, the detergent or the fabric softener flows to the outside of the detergent container 40, causing problems in use, such as requiring careful attention when the detergent and fabric softener is injected. there was.

On the other hand, in recent years, due to the diversification and improved functionality of the detergent, the use of a liquid laundry detergent in a liquid state as well as a powdered laundry detergent in the form of fine particles is increasing.

In view of this, since the above-described detergent supply apparatus can supply only the laundry detergent in the form of a powder, the fabric softener and the bleach in the form of liquid into the laundry space, and the laundry detergent in the laundry administration in the preliminary washing and the main washing process. It can supply only laundry detergent in powder form, and it is not equipped with liquid detergent supply means for separately supplying liquid detergent for performing washing function instead of bleaching and rinsing functions. There was a limit to satisfaction.

The present invention has been made to solve the conventional problems as described above, an object of the present invention is to install a detergent container of the detergent supply device to be separated from the main body of the drum washing machine to facilitate the cleaning operation of the detergent container. In addition, it is possible to supply various detergents even when the detergent container is not withdrawn or separated from the main body, and the detergent of the drum washing machine can be supplied separately with a liquid laundry detergent to perform the washing function instead of the bleaching and rinsing functions. It is for the purpose of providing a device.
