In addition, a washing machine having a residual water discharge device according to the present invention includes a cabinet, a tub installed inside the cabinet to wash the fresh water, a drum rotatably installed inside the tub to accommodate the wash water, and installed in the tub. A drain pipe extending outward, a discharge pipe installed at one side of the drain pipe and extending outside the cabinet, a valve installed at one side of the discharge pipe to open and close the discharge pipe, and installed between the valve and the cabinet according to a user's operation It characterized in that it comprises a residual water discharge device including an operation means for opening and closing the.

Hereinafter, an embodiment of a washing machine having a residual water discharge device according to the present invention will be described in detail with reference to the accompanying drawings.

For convenience of explanation, a drum washing machine will be described as an example. In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation.

In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator.

Therefore, definitions of these terms should be made based on the contents throughout this specification.

3 is a cross-sectional view showing a washing machine having a residual water discharge device according to the present invention, Figure 4 is a front view showing a washing machine according to the present invention.

3 to 4, a washing machine having a residual water discharge device according to the present invention includes a cabinet 10, a tub 12 installed inside the cabinet 10 to wash water, and a tub 12 inside the tub 12. A drum 14 rotatably installed on the drum 14 to accommodate the wash water, a drain pipe 16 installed on the tub 14 and extending outside the cabinet 10, and a drain pipe 16 disposed on one side of the cabinet 10 to the outside of the cabinet 10. Discharge pipe 20 extending to the outlet, the valve 30 is installed on one side of the discharge pipe 20 to open and close the discharge pipe 20, and installed between the valve 30 and the cabinet 10 according to the user's operation valve ( 30 and the operation means 40 and 50 to open and close the water supply prevention means 70 is installed in the operation means (40, 50) to detect whether the valve 30 is opened or closed to determine whether water supply operation is started. It is made to include.

Thus, when the user drives the operation means (40, 50) installed outside the cabinet 10 after the washing operation is finished, the valve 30 is opened while the washing water remaining in the drain pipe (16) along the cabinet (20) (10) It is discharged to the outside.

Here, the valve 30 is composed of a cock valve that is opened and closed by the rotational force transmitted by the operation means 40, 50, the operation means 40, 50 are installed in the valve 30 and to the outside of the cabinet 10 It includes an extended drive shaft 40, and a lever 50 is installed on the outer end of the drive shaft 40 and slidably disposed on the outer wall of the cabinet 10.

In this way, the user can open and close the valve 30 by a simple operation of rotating the lever 50, so that the remaining water can be easily discharged from the drain pipe 16.

5 is a perspective view showing a residual water discharge device according to the present invention, Figure 6 is a block diagram showing a residual water discharge device according to the present invention.

5 to 6, the water supply preventing means 70 is installed in the sensing piece 72 installed on the drive shaft 40 and the cabinet 10 corresponding to the sensing piece 72. The switch includes a switch 74 for transmitting an electrical signal and a controller 76 for determining whether the water supply valve 15a is opened or closed in accordance with the signal received by the switch 74.

As a result, when the user rotates the lever 50 in the 'closed' state, the sensing piece 72 is also rotated, and the lever 50 and the sensing piece 72 are rotated, so that the valve 30 is completely closed. When the sensing piece 72 is in contact with the knob of the switch 74 to transmit an electrical signal from the switch 74, the control unit 76 maintains a state in which the water supply valve 15a can be opened. .

On the contrary, when the lever 50 is not completely rotated in the 'close' direction and the sensing piece 72 does not contact the switch 74, the control unit 76 maintains the water supply valve 15a in the closed state so that the water supply operation is performed. You won't lose.

As a result, the water supply operation is performed in the state in which the discharge pipe 20 is opened to prevent the wash water from being lost to the outside of the tub 12.

Looking at the operation of the washing machine having a residual water discharge device according to the present invention configured as described above are as follows.

First, when the user rotates the lever 50 in the 'open' direction after the washing operation is completed, the valve 30 is opened while the drive shaft 40 is rotated, so that the discharge pipe 20 is opened and remains inside the drain pipe 16. Washing water to be discharged to the outside of the cabinet 10 along the discharge pipe (20).

After the wash water inside the drain pipe 16 is completely discharged by this operation, the sensing piece 72 contacts the switch 74 when the user rotates the lever 50 completely in the 'close' direction to close the valve 30. The electrical signal is transmitted.

In response to the signal received from the switch 74, the control unit 76 switches the water supply valve 15a to an openable state, thereby enabling the following washing operation.

At this time, if the lever 50 is not completely rotated in the 'closed' direction after the remaining water is completely discharged, the sensing piece 72 and the switch 74 are not in contact with each other, so that the water supply valve 15a is maintained in a closed state.

As a result, the water supply operation is performed in the state in which the discharge pipe 16 is opened, thereby preventing the wash water which is fresh in the tub 12 from being lost to the outside of the cabinet 10 along the discharge pipe 20.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims. I will understand.

In addition, the drum washing machine has been described as an example, but this is merely exemplary, and the residual water draining device of the present invention may be used in any product driven by fresh water rather than the residual water draining device used in the drum washing machine.

Accordingly, the true scope of protection of the present invention should be defined by the following claims.

Residual water discharge device and a washing machine having the same according to the present invention configured as described above can discharge the wash water remaining in the drain pipe by a simple operation to rotate the lever for the convenience of the user, the residual water freezes in winter There is an advantage that can prevent malfunction and breakage of the washing machine generated.
