The present invention relates to a washing machine having a simple drying function by wind.

In recent years, it has been aimed to give a washing machine a simple drying function by wind. 15 shows an example of such a washing machine with a drying function. The washing machine forms an air vent 2 on a lid 1 located at the top, and rotates an inner tank (not shown) for washing, dehydrating and drying to inhale outside air from the air vent to generate wind. It is made to dry by contacting the laundry in the inner tank.

16 shows another example of such a washing machine with a drying function. The washing machine forms an air vent 3 on the cover 1, installs an air vent cover 4 covering the air vent 3 so as to be openable and closes, and opens the air vent cover 4 with the inner tub (this is also the case). By rotating the air (not shown), the outside air is sucked from the air vent 3 to generate wind, and the wind is brought into contact with the laundry placed inside the inner tank to dry.

In the above two examples of washing machines, the former is a small washing machine such as a hairpin enters the vent (2), it is sandwiched between the stirring body located in the lower part of the inner tank and the bottom surface of the inner tank to hinder the rotation of the stirring body. May cause malfunction. In the periphery of the air vent 2, dust, dust, and the like tend to collect, and it is likely to enter the air vent 2 and impair the washing effect.

On the other hand, the latter is eliminated by the vent cover 4, but it is cumbersome to open the vent cover 4 every time the dry operation is performed. Alternatively, if the drying operation is performed while forgetting to open the vent cover 4, the intake air from the vent 3 cannot be sufficiently obtained, and as a result, the drying is not sufficiently performed.
