Abstract

A detergent supplying device for a laundry treatment apparatus prepared by the present invention divides the inside of a dispenser into a hot water supply unit and a cold water supply unit in order to prevent backflow of cold water into a hot water hose or the backflow of hot water into a cold water hose. In addition, the laundry treatment apparatus can increase the amount of wash water supplied to the front of a detergent box and, in turn, reduce detergent residues by removing additional structure for preventing backflow. A cold water/hot water dividing rib for dividing the cold water supply unit and the hot water supply unit can guide the flow of cold or hot water. The width of a flow path toward the front is reduced by the cold water/hot water dividing rib in order to increase the flow velocity so that the wash water can be smoothly supplied toward the front even at low water pressures. Therefore, detergent residues can be minimized by increasing the amount of wash water supplied to the front of the detergent box.

The top cover 6 is provided with a detergent supply device 20 for supplying detergent and washing water.

Fig. 2 is a perspective view showing the detergent supply device 20 shown in Fig. 1, and Fig. 3 is a plan view of the detergent supply device 20 shown in Fig.

Referring to FIGS. 2 and 3, the detergent supply device 20 includes a detergent box 30 and a dispenser 40.

The detergent box 30 is installed in the detergent box housing 33 installed in the cabinet 4 or the top cover 6 so as to be detachable. The detergent box 30 is formed with an open top surface. A handle 31 is mounted on the front surface of the detergent box 30 so that the user can hold it or push it in. The detergent box 30 is formed by being divided into a detergent receiving portion 30a for receiving the detergent and a softening agent accommodating portion 30b for accommodating the fabric softening agent. The detergent storage portion 30a and the softening agent storage portion 30b are partitioned by a detergent box partition rib 30c. However, the present invention is not limited thereto, and the detergent containing portion 30a may be divided into a space for accommodating the laundry detergent and a space for accommodating the detergent for the laundry.

The dispenser (40) is installed on the opened upper surface of the detergent box (30). The dispenser 40 comprises a cover part 50 and a shower part 60.

The cover portion 50 is formed in a panel shape so as to cover the opened upper surface of the shower portion 60. The cover part 50 is provided with first and second cold water hose connecting ports 51 and 52 to which a cold water hose is connected and a hot water hose connecting port 53 to which a hot water hose (not shown) is connected. The first cold water hose connecting port 51 is connected to a cold water hose for supplying cold water to the softener receiving portion 30b and the second cold water hose connecting port 52 supplies cold water to the detergent receiving portion 30a A cold water hose is connected.

The shower part 60 is installed on the opened upper surface of the detergent box 30 and has an upper surface opened. The shower 60 is divided into a detergent shower 70 and a softener shower 80 so as to correspond to the detergent receiver 30a and the softener receiver 30b of the detergent box 30 . The hot water hose connecting port (53) and the second cold water hose connecting port (52) are communicated with the detergent shower part (70). The first coolant hose connection port (51) communicates with the softener shower part (80).

The detergent shower part 70 is formed by partitioning the space between the cold water supply part 71 and the hot water supply part 72 by the cold / hot water partition ribs 90.

The cold / hot water partition rib 90 protrudes upward from the bottom surface of the detergent shower part 70. The cold / hot water partition ribs 90 are multi-folded in a 'C' shape. In the present embodiment, the hot water supply part 72 is an inner space of the cold / hot water partition rib 90, and the cold water supply part 71 corresponds to the outer space of the cold / hot water partition rib 90 Hot water compartment ribs 90 are connected to the inner space of the cold / hot water partition ribs 90 and the hot water hose connection ports 53 are communicated with the second cold water hose connectors 52 . Since the hot water is generally used selectively and cold water is always used, it is preferable that the outer space of the cold / hot water partition rib 90 corresponds to the cold water supply unit 71. However, the present invention is not limited to this, and it is of course possible that the positions of the hot water supply unit 72 and the cold water supply unit 71 are changed.

The plurality of cold / hot water partition ribs 90 are spaced apart from each other by a predetermined distance so as to form a space 93 between the cold water supply unit 71 and the hot water supply unit 72. In the present embodiment, the cold / hot water partition rib 90 is composed of two first and second ribs 91 and 92, but the present invention is not limited thereto. .

In the spacing space 93, a plurality of discharge holes 93a are spaced apart from each other by a predetermined distance. The water supplied to the cold water supply unit 71 may overflow and flow into the spacing space 93 beyond the cold / hot water partition rib 90. The water that has flowed into the spacing space 93 can escape through the discharge holes 93a without flowing back to the hot water supply unit 72. [ Even if the water supplied to the hot water supply unit 72 overflows and flows into the spacing space 93, the hot water supply unit 71 escapes through the discharge holes 93a of the spacing space 93, It is possible to prevent the phenomenon of backward flow to the < / RTI >

A plurality of hot water discharge holes 72a are formed on the lower surface of the hot water supply part 72 so as to be spaced apart from each other by a predetermined distance. The hot water supplied from the hot water hose (not shown) to the hot water supply unit 72 is discharged to the detergent box 30 through the hot water discharge holes 72a. The hot water supply part 72 is formed with a discharge port 72b for discharging hot water that has not been discharged through the hot water discharge holes 72a.

The cold water supply unit 71 corresponds to the outer space of the cold / hot water partition rib 90, and the cooling water flows between the first rib 91 and the outer surface of the detergent storage unit 70. The flow rate of the cold water is further increased because the channel width of the cold water is narrower than when the cold / hot water partition ribs 90 are not provided. The cold water supply unit 71 is provided with a plurality of cold water discharge holes 71a on the downstream side in the flow path of the cold water.

Since the plurality of cold water discharge holes 71a are formed to extend across the front surface portion 70a and the bottom surface 70b of the detergent receiving portion 70, cold water is supplied toward the front of the detergent box 30 The detergent in the detergent box 30 can be washed down more smoothly. The plurality of cold water discharge holes 71a are spaced apart from each other by a predetermined distance in the lateral direction. However, the present invention is not limited thereto, and a plurality of cold water discharge holes 71a may be formed at predetermined intervals Do.

The operation according to the embodiment of the present invention will be described as follows.

First, when cold water and hot water are both supplied through the cold water hose (not shown) and the hot water hose (not shown), the hot water is supplied to the hot water supply unit 72 through the hot water hose connecting port 53. The hot water supplied to the hot water supply unit 72 is supplied into the detergent box 30 through the plurality of hot water discharge holes 72a.

The cold water is supplied to the cold water supply unit 71 through the second cold water hose connection port 52. The cold water from the second cold water hose connection port 52 flows forward along the space between the first rib 91 and the inner wall 71c of the detergent receiver 71. [ And the first rib 91 serves to guide the flow of the cold water forward. Since the width of the omni-directional flow path 100 is smaller than that of the case where the first rib 1 is not present, the flow rate of the cold water may increase. Therefore, even at a low water pressure, the cold water can flow forward at a higher speed. The cold water flowing forward is supplied to the front of the detergent box 30 through the cold water discharge holes 71a. In the conventional case, the amount of cold water reaching forward when the water pressure is low is relatively small, and the detergents in front of the detergent box 30 can not be dissolved. In this embodiment, however, The amount of the cold water supplied to the front of the detergent box 30 becomes sufficient, so that the detergent in the detergent box 30 can be effectively dissolved and the amount of residual detergent can be reduced.

Meanwhile, when the cold water supplied to the cold water supply unit 71 overflows, it can flow into the spacing space 93 between the first ribs 91. The cold water flowing into the spacing space 93 can escape into the detergent box 30 through the discharge holes 93a to prevent the cold water from flowing back to the hot water supply unit 72 side. That is, when only cold water is supplied, the reverse flow of the cold water through the hot water hose connecting port 53 can be prevented. Therefore, since the supplied cold water is smoothly supplied to the detergent box 30, the amount of detergent remaining in the detergent box 30 can be minimized.
