Washing machine

The present invention relates to a washing machine including a touch panel type display operation unit.

The operation panel of the conventional washing machine is a combination of a display unit that displays a seven-stage type such as time and various button-type operation units. However, in recent years, in order to display various states in the operation of the washing machine, the display portion using the character liquid crystal has been increasing. In the display portion of the character liquid crystal, the lower surface is extraordinarily large and flat compared with the display portion of the seven-segment type. Therefore, there is a problem that condensation occurs when the moisture is emitted from the outside, and the visibility is deteriorated. Therefore, in the display portion of the conventional character liquid crystal, in order to prevent the intrusion of moisture, the potting material is filled on the control substrate connected to the character liquid crystal or the like, and the packing is inserted between the operation panel and the surface. It is handled by sealing (for example, refer to Patent Document 1).
