Abstract

The present invention relates to washing machines, and more particularly, to a detergent introducing device to a washing machine which can prevent early introduction of detergent, such as fiber softener and the like. The washing machine includes a cabinet which is an exterior of the washing machine, a drum rotatably mounted in the cabinet, and a detergent introducing device drawably mounted in the cabinet for supplying detergent, such as fiber softener, and the like, to the drum, wherein the detergent introducing device includes a detergent box having a chamber for holding the detergent, such as the fiber softener, and a first siphon tube projected upward from the chamber, and an early introduction preventive portion mounted on the detergent box for preventing early introduction of the fiber softener in the chamber into the first siphon tube. The washing machine of the present invention has the following advantages. The early introduction preventive portion of the detergent introducing device permits to prevent early introduction of fiber softener in the detergent box into the drum even if an impact is applied to the detergent box having the detergent, such as the fiber softener, held therein. Accordingly, as a loss of the fiber softener can be reduced, a washing effect can be maximized, and an effective washing can be done.

Claims

1. A washing machine comprising:

a cabinet which is an exterior of the washing machine, a drum rotatably mounted in the cabinet, and a detergent introducing device drawably mounted in the cabinet for supplying detergent, such as fiber softener, and the like, to the drum, wherein the detergent introducing device includes;

a detergent box having a chamber for holding the detergent, such as the fiber softener, and a first siphon tube projected upward from the chamber, and

an early introduction preventive portion mounted on the detergent box for preventing early introduction of the fiber softener in the chamber into the first siphon tube.

2. The washing machine of claim 1, wherein the detergent introducing device further includes a siphon cover having a second siphon tube for capping the first siphon tube.

3. The washing machine of claim 1, wherein the early introduction preventive portion is a plate projected upward from a bottom of the chamber.

4. The washing machine of claim 3, wherein the early introduction preventive portion has a height enough to prevent the fiber softener from being introduced into the first siphon tube even if the fiber softener rushes.

5. The washing machine of claim 4, wherein the early introduction preventive portion has a top edge positioned higher than or the same with a top of the first siphon tube.

6. A washing machine comprising:

a cabinet which is an exterior of the washing machine, a drum rotatably mounted in the cabinet, and a detergent introducing device drawably mounted in the cabinet for supplying detergent, such as fiber softener, and the like, to the drum, wherein the detergent introducing device includes;

a detergent box having a chamber for holding the detergent, such as the fiber softener, and a first siphon tube projected upward from the chamber,

a siphon cover mounted on an upper portion of the chamber, the siphon cover having a second siphon tube projected downward to cap the first siphon tube, and

an early introduction preventive portion mounted on the chamber or the siphon cover for preventing early introduction of the fiber softener in the chamber into the first siphon tube.

7. The washing machine of claim 6, wherein the early introduction preventive portion is a plate projected down from a ceiling of the siphon cover.

8. The washing machine of claim 7, wherein the early introduction preventive portion and the first siphon tube are overlapped in a vertical direction.

9. The washing machine of claim 8, wherein the early introduction preventive portion has a height the same with the first siphon tube.

10. The washing machine of claim 8, wherein the early introduction preventive portion has a height different from a height of the first siphon tube.

11. The washing machine of claim 7, wherein the early introduction preventive portion has a width substantially the same with a diameter of the second siphon tube.

12. The washing machine of claim 7, wherein the early introduction preventive portion is a plate projected upward from a bottom of the chamber.

13. A detergent introducing device comprising:

a detergent box drawably mounted in a washing machine, having a chamber for holding detergent, such as fiber softener, and a first siphon tube projected upward from the chamber,

a siphon cover mounted on an upper portion of the chamber, the siphon cover having a second siphon tube projected downward to cap the first siphon tube, and

an early introduction preventive portion mounted on the chamber or the siphon cover for preventing early introduction of the fiber softener in the chamber into the first siphon tube.
