Description

  The present invention relates to a washing / drying machine that stores clothes in an inner tub and performs washing to drying.

Conventionally, in this type of washing and drying machine, the process from washing to drying is performed by blowing drying air to the inner tub 32 that stores the clothes to evaporate the moisture contained in the clothes (for example, patents). Reference 1). As shown in FIG. 9, an inner tub 32 rotatably provided in the outer tub 31, and a stirring blade 33 for stirring clothes inside the inner tub 32, the inner tub 32 and the stirring wing 33 are It is rotated by the driving means 34. The inner tub 32 accommodates clothing and has a plurality of water holes 35 on its peripheral wall surface. A high-temperature hot air blowing means 36 for supplying drying air to the inner tank 32 and a heater 37 for heating the drying air are provided, and the blowing nozzle 38 provided above the inner tank 32 is directed toward the center of the stirring blade 33. The air for drying is blown out.
JP-A-9-774

  However, in the conventional configuration, when the clothes are dried, the clothes are splashed and stirred by the forward and reverse rotation of the stirring blade 33. At this time, the drying air heated from the blowing nozzle 38 is sprayed and brought into contact with clothes to promote drying. After the drying air collides with clothes in the inner tub 32, the air passes through a water passage hole 35 provided in the inner tub 32, passes through the space between the outer tub 31 and the inner tub 32, and is below the outer tub 31. It is discharged from the exhaust port provided. When the clothes are stirred by the rotation of the stirring blade 33, the clothes may get entangled, and the tangled clothes take time to dry and the finish is also poor. Further, when the amount of clothes is large, it is difficult for hot air to hit the lower layer clothes in the inner tub 32 and the drying time becomes longer.

  The present invention solves the above-described conventional problems, and provides a washing and drying machine capable of suppressing entanglement of clothes, improving the finish, improving drying efficiency, saving energy and shortening drying time. For the purpose.

  In order to solve the conventional problems, the washing and drying machine of the present invention is provided with a stirring plate having a predetermined inclination angle on a stirring blade, and a blade is provided between the stirring blade and the stirring plate.

  As a result, the clothes move mainly up and down so that they do not get entangled, and the rotation of the stirring blades guides the warm air to the lower layer of the inner tank by the blades between the stirring blades and the stirring plate, and allows the clothes to pass through. Improve energy saving and shorten drying time.
