It is preferably applied to. In addition, the planar heater 160 is preferably used for the regeneration of the absorbent material 140.

That is, on the inner surface of the inner cover 110, the outer cover 130 or the door duct 120, a surface heater 160 for regeneration of the absorbent material 140 is first installed, and the supporter 150 and the absorber thereon are installed thereon. The material 140 is provided.

The planar heater 160 is for drying the absorbent material 140 having a wide applied range in a short time. When the absorbent material 140 is heated by the planar heater 160, the absorbed material is dried while the absorbed material 140 is dried. Can be reused.

The surface heater 160 is preferably operated after the absorbent material 140 absorbs some of the moisture in the air introduced into the door 100 after the washing and drying of the dishes is completed. However, the time of operation and the time of operation can be changed as necessary. The supporter 150 for supporting the absorber material 140 on the surface heater 160 is coupled, and the absorber material 140 is coated on the supporter 150.

The supporter 150 may be made of any material capable of applying the absorbent material 140 such as silica-ceramic, stainless steel, or plastic, but has a durability against heat that does not deform when the surface heater 160 is operated. It is desirable to have.

The absorbing material 140 is applied on the supporter 150 as a zeolite, and a membrane or coating film is preferable rather than a bead shape. In order to provide the absorbent material 140 in a thin film form, the existing structure (inner cover, outer cover, door duct) may be used as it is without providing a separate component.

That is, when the absorbent material 140 is provided in a thin film form, it can be directly applied to any surface of the cabinet 10 or the inner surface of the door 100, so that a separate component for dehumidification is not required. Therefore, the structure of the dish washer () is not complicated and it is possible to improve the function and ease of manufacturing the product.

The absorbent material 140 may be formed on the inner cover 110, the outer cover 130, or the inner surface of the door duct 120 as well as on one side of the tub 200, but the absorber material 140 may be formed on the inner cover ( When applied to the 110) it is possible to improve the thermal efficiency.

In more detail, since the inner cover 110 faces the tub 200 side, the inner cover 110 faces the tub 200 that is relatively hot compared to the outside of the cabinet 10 even after the washing and drying of the dishes are completed.

Therefore, since the inner cover 110 is relatively hot compared to the outer cover 130 due to heat conduction, the surface heater 160 takes less time to heat up to a temperature necessary for dehumidifying the absorbent material 140.

That is, when the absorbent material 140 is applied to the inner cover 110 side, the energy required to heat the planar heater 160 may be reduced, thereby improving thermal efficiency in terms of driving the planar heater 160.

The absorbing material 140 coated on the supporter 150 is used for washing and drying dishes, and when wet air flows into the inside of the door 100, absorbing moisture in the air makes dry air. The air dried by the absorbent material 140 is exhausted through the air discharge unit 132, and the absorbent material 140 absorbing moisture is dried and reused by the surface heater 160.
