On the other hand, a gasket for sealing between the inlet and the tub is installed around the inlet.

However, since such a conventional drum washing machine does not have a separate device or configuration for removing washing water remaining in the gasket even after completion of washing or dewatering of the laundry, the washing water remaining in the gasket Foreign matter such as fungi is generated or odor is generated, which causes discomfort to the user and worsens the sanitary condition of the user.

In addition, foreign substances such as fungi due to washing water remaining in the gasket may adhere to the laundry, or a bad smell may permeate the laundry, thereby deteriorating the washing performance.

The present invention has been conceived to solve the problems of the conventional art as described above, and it is an object of the present invention to provide a drum washing machine capable of collecting laundry water and moisture remaining in a gasket and discharging it naturally by forming a drainage part and a drainage hole in a gasket provided between the door and the inlet. And to provide the above-mentioned objects.

It is another object of the present invention to provide a drum washing machine capable of collecting laundry water, moisture, and the like remaining in a gasket and forcibly draining water remaining in the gasket by further forming a forced drainage means in the drainage portion or the lower portion of the drainage hole in the gasket do.

It is another object of the present invention to provide a drum washing machine in which an air blowing device and an air blowing guide portion are formed on an upper portion of a gasket so that washing water remaining in other portions except a lower portion of the gasket can be effectively sent to a drain portion formed in a lower portion of the gasket For other purposes.

It is another object of the present invention to provide a drum washing machine capable of improving washing quality and sanitation environment of a user by preventing impurities such as molds generated by washing water and moisture remaining in the gasket from being impregnated in laundry, The present invention also provides another object of the present invention.

In order to accomplish the above-mentioned object, the present invention provides a cabinet comprising: a cabinet having a charging port into which laundry is charged; A door installed in the cabinet for opening and closing the inlet of the cabinet; A tub installed inside the cabinet; A drum installed to rotate inside the tub; And a gasket installed between the inlet of the cabinet and the tub to seal between the door and the tub, wherein the gasket is provided with a gasket for preventing contaminants from being generated in the center of the lower surface of the inner surface of the gasket, And a drainage part for the drum washing machine is formed.

According to the above-described structure, the washing water or moisture remaining on the gasket after the completion of the washing course of the drum washing machine can be drained by the drainage part, and the odor generated in the gasket can be reduced.

Here, the drainage portion is recessed at the lower end of the gasket. That is, by forming the drain portion in a negative direction, the collection efficiency of the washing water and the like can be increased, and if the drain portion is inclined, the collection efficiency can be further increased.

Further, a drain hole may be formed in the drain portion. In the case where only the drainage portion is formed, it is inevitable to naturally dry or evaporate in order to remove the washing water collected in the drainage portion. However, if a drainage hole is further formed in the drainage portion, the washing water collected in the drainage portion can be discharged smoothly The removal efficiency of washing water and the like can be increased.

According to another aspect of the present invention, there is provided a washing machine comprising: a cabinet having a charging port into which laundry is charged; A door installed in the cabinet for opening and closing the inlet of the cabinet; A tub installed inside the cabinet; A drum installed to rotate inside the tub; A gasket installed between the inlet of the cabinet and the tub to seal between the door and the tub; A drainage portion formed at a lower central portion of the inner surface of the gasket for collecting residual water or washing water; And a forced drainage means for removing residual water or washing water collected in the drainage portion from the gasket.

In this way, by providing the forced drainage means together with the drainage portion, the drainage efficiency of the wash water and the like can be further increased.

Preferably, the forced drainage means is a drain pump installed at a lower portion of the cabinet to discharge washing water to the outside, and the drain pump is connected to a drain hole formed in the drainage portion. That is, it is also possible to drain the washing water collected in the drainage unit by using a drainage pump that is installed before, without having to install a separate forced drainage means.

In addition, a connection pipe communicating with the forced drainage means may be mounted on the drain hole. By forming the connecting pipe in this manner, the washing water collected in the drainage portion can be smoothly guided to the forced drainage means.

Meanwhile, the drainage part is formed to be depressed downward, and natural drainage is performed through the drainage hole. As a result, the collection efficiency of washing water and the like can be increased.

The forced drainage means may be a drain pump installed at a lower portion of the cabinet for discharging washing water to the outside, and a separate suction fan installed between the drainage portion and sucking residual water or washing water collected in the drainage portion. It is effective that the suction fan is a fan motor in which a fan and a motor are integrally formed and is waterproofed.

In this manner, by providing a separate suction fan as the forced drain means in addition to the drain pump, it is possible to drain the washing water and the like that do not drain naturally.

In addition, the suction fan is preferably an axial flow fan, which is advantageous in forming a flow path for flowing wash water and the like. That is, since the flow path is formed in the front-rear direction of the axial flow fan, the flow path structure can be simplified.

Meanwhile, an air blowing device for blowing air to collect the residual water or washing water present on the surface of the gasket can be further formed on one side of the gasket. Therefore, washing water or the like which can not reach the drainage part formed at the lower part of the gasket can be sent to the drainage part.

In this case, it is more effective that at least one blowing guide portion is formed in the gasket connected to the outlet end of the blowing device so that the air blown by the blowing device can be blown along the surface of the gasket. If there is no air guide, the air from the air blowing device can be discharged directly into the space inside the drum without blowing along the surface of the gasket.

In addition, it is preferable that the air blowing device operates in a state where the door is closed. If the door is opened, the washing water remaining in the gasket during the inflow / outflow of air can be naturally dried.

Meanwhile, the air blowing device is formed at a position facing the drainage portion to blow air evenly over the entire surface of the gasket.

In addition, a check valve may be provided in the connection pipe, or a check valve may be further provided between the forced drainage means and the drainage pump. When the drain pump is operated to drain contaminated washing water from the tub after completing a normal washing course of the washing machine, the washing water collected in the drain portion of the gasket should not flow into the drain pump. The washing water collected in the drainage unit can be prevented from being introduced into the drainage pump when the washing water is drained from the tub after completion of the washing course.

Meanwhile, antimicrobial substances such as fermented lactic acid bacteria of Kimchi may be applied to the drainage part to reduce foreign matter such as fungi in the gasket.
