A gasket 150 for sealing between the charging port 102 and the tub 110 is installed along the periphery of the charging port 102.

3, the gasket 150 has a ring or annular shape having a predetermined height, and the gasket 150 is folded so that the middle portion thereof is overlapped. That is, referring to FIG. 2, it can be seen that the gasket 150, which is shaped to surround the upper and lower portions of the door 130, is folded over.

A heating member for removing the washing water or moisture remaining in the gasket 150 is installed in the gasket 150 or around the gasket 150, which will be described below with reference to the drawings.

Fig. 4 is an enlarged cross-sectional view of the portion " A "in Fig. 2, showing a gasket and a heating member according to an embodiment of the present invention. Fig. 5 is an enlarged cross- Fig.

As shown in FIG. 4, a heating member 160 for removing moisture present in the lower central portion of the inner surface 151 of the gasket 150 is formed. Washing, rinsing, dewatering, or the like, washing water or moisture accumulates in the lowermost portion of the gasket 150 and the peripheral region around the lowermost portion of the gasket 150. This is a phenomenon that occurs because the gasket 150 is approximately circular.

Such residual washing water or moisture includes a mixture of detergent and detergent contained in the laundry and a detergent. If the washing water remaining in the gasket 150 or the moisture remaining in the gasket 150 is left for a long time in the drum 120 having a high humidity, the washing water may be decomposed or foreign matter such as mold may be generated. .

At this time, the central portion of the lower end of the inner side surface 151 of the gasket 150 is heated by using the heating member 160, so that the washing water and moisture in the lower middle portion of the inner surface of the gasket 150 can be evaporated.

Here, the heating member 160 may be embedded in the lower end of the gasket 150. The amount of heat conducted from the heat generating member 160 to the surface of the gasket 150 can be increased by embedding the heat generating member 160 in the lower end portion of the gasket 150. [

The gasket 150 is formed by injection molding using a rubber material. Therefore, it is effective that the heat generating member 160 is also embedded in the gasket 150 by injection.

5 shows a process of injection molding the gasket 150 with the heat generating member 160 built therein.

As shown in FIG. 5, the gasket 150 is composed of an upper molded product 150a and a lower molded product 150b. Here, a heating member receiving portion 150c for accommodating the heating member 160 is provided on the upper molded product 150a of the gasket 150. [

A mold (not shown) having a structure capable of forming the heat generating member receiving portion 150c for injecting the upper molded product 150a of the gasket 150 is used.

5A), the heat generating member 160 is inserted into the heat generating member accommodating portion 150c (FIG. 5B), and the lower molded product 150b is inserted into the heat generating member accommodating portion 150c The gasket 150 having the heat generating member 160 embedded therein can be obtained by injection (FIG. 5C).

It is effective that the heat generating member receiving portion 150c is formed larger than the heat generating member 160 so that a gap is formed between the heat generating member 160 and the heat generating member receiving portion 150c, The gap between the accommodating portions 150c is filled with the lower ejection member 150b so that the heating member 160 is firmly embedded in the upper ejection member 150a and the lower ejection member 150b.

In the figure, reference numeral 151 denotes an inner surface of the gasket, and reference numeral 152 denotes an outer surface of the gasket.

The heating member 160 has a substantially circular cross section and is formed of a resistor and includes a heating body 162 radiating heat and an insulator 162 surrounding the heating body. The gasket 150 itself is made of rubber and the heating element 162 is directly connected to the gasket 150 without a separate insulator 161. In this case, It can also be embedded.

In the case where the gasket 150 is so thin that it is difficult to embed the insulator 161, only the heat element 162 may be built in the gasket 150 without the insulator 161. In this case, 150c may be made smaller according to the size of the heating element 162. [ Here, it is preferable that the heating member 160 or the heating element 162 is a heater or a heating wire.

On the other hand, the heating member can be provided at other positions, which will be described below with reference to the drawings.

As described above, when the thickness of the gasket 150 is so small that it is difficult to install the heat generating member 170 internally, the gasket 150 may be provided below the gasket 150 so as to be spaced apart from the lower end of the gasket 150, (Not shown).

Here, when the heating member 170 is attached to the inner side surface 151 or the outer side surface 152 of the lower end of the gasket 150, it is effective that the heating member 170 is a sticky adhesive heat line. 3, the heat generating member 170 may be attached to the inner side surface 151 or the outer side surface 152 of the gasket 150 in the form of a thin sticky adhesive heat wire having a predetermined area .

At this time, when the heat generating member 170 made of a sticky adhesive heat ray is provided on the inner side surface 151 of the lower end portion of the gasket 150, it is effective to perform the waterproof treatment on the heat generating member 170. This is because washing water or moisture is collected mainly on the inner side surface 151 of the lower end portion of the gasket 150, and if the water-proofing treatment is not performed on the heat generating member 170, there is a danger to the user due to a short circuit or the like.

Meanwhile, it is preferable that the heat generating members 160 and 170 formed of a heater or a heat line are strip type bent several times in order to maximize a heating value. By embedding hot wire bent in a substantially jig-like shape inside the gasket 150 or arranging sticker-bonded hot wires in a jig-like shape, more heat can be applied to the inside or the surface of the gasket 150.

Here, it is preferable that the resistance value of the heating element of the heating member 160 or 170 is adjusted so that the maximum heating temperature does not exceed 150 ° C. If the temperature exceeds 150 ° C, the gasket 150 may melt.

It is preferable that the heating members 160 and 170 heat only a portion corresponding to 1/3 to 1/2 of the entire length of the gasket 150. That is, it is sufficient that the portion corresponding to 1/3 to 1/2 of the circumferential length of the entire gasket 150 can be heated by the heating members 160 and 170 based on the lowermost end of the gasket 150. This is because, This is because it is sufficient to provide the heat generating member only at the portion where the moisture mainly collects around the gasket 150 including the lowermost end portion of the gasket 150.

Meanwhile, it is effective that the heating members 160 and 170 operate when the door 130 is closed. If the door 130 is opened, air can be introduced into the drum 120, and moisture, washing water, and the like present in the gasket 150 can be naturally dried / evaporated, so that the heating members 160 and 170 need to be operated There is no.

Further, it is preferable that the heating members 160 and 170 stop operating when the door 130 is opened. That is, when power is supplied to the heat generating members 160 and 170 while the door 130 is closed and heat is generated in the heat generating members 160 and 170, the user opens the door 130 to input or take out the laundry, It is preferable that the power supply to the heat generating members 160 and 170 is cut off so that the heat generating members 160 and 170 are not operated.

In order to achieve the above-mentioned object, the present invention provides a cabinet including a cabinet 101 having a charging port 102 into which laundry is charged, a cabinet 101 installed in the cabinet 101 for opening and closing a charging port 102 of the cabinet 101, A door 130 and a tub 110 installed inside the cabinet 101. The drum 120 is installed to rotate inside the tub 110. The door 130 and the tub 110 are connected to each other by a cabinet A gasket 150 installed between the inlet 102 of the gasket 101 and the tub 110 and a door 130 after the laundry is taken out of the drum 120, (160, 170) provided on the gasket (150) so as to prevent the generation of contaminants in the lower central portion of the tub (151).

Here, since the shape or the installation structure of the heat generating members 160 and 170 is the same as that shown in FIG. 4, a description thereof will be omitted.

The heat generating members 160 and 170 may be spaced apart from the bottom of the lower end of the gasket 150 or may be embedded in the gasket 150.

In addition, the heating members 160 and 170 are not operated when the door 130 is opened, and are automatically or manually operated during a washing course. That is, power may be supplied to the heat generating members 160 and 170 only when the user selects the power source, or power may be supplied to the heat generating members 160 and 170 at the last stage of the washing course.
