Washing and drying machine

Abstract

A washing and drying machine has an object to improve a drying efficiency of a laundry and reduce a drying time, and includes an outer drum; an inner drum rotated in this outer drum and having a substantially cylindrical shape to constitute a storage chamber therein; a takeout port which is constituted in one end surface of a cylinder of this inner drum in an axial direction and via which the laundry is to be taken or introduced; a plurality of through holes which are formed around a side surface of the cylinder of the inner drum and in the other end surface of the cylinder in the axial direction and from which water is discharged during the washing and through which circulation air for drying circulates during the drying; and a blowing regulation unit which blows the air for drying into the storage chamber from the side of one end or the other end of the cylinder of the inner drum in the axial direction and which allows the air to flow from the through holes on the other end side or from the one end side and which inhibits outflow of the air for drying from the other through holes.

1 . A washing and drying machine which washes laundry and dries it after end of the washing, comprising:
 an outer drum;   an inner drum rotated in the outer drum and having a substantially cylindrical shape to constitute a storage chamber therein;   a takeout port which is constituted in one end surface of a cylinder of the inner drum in an axial direction and via which the laundry is to be taken or introduced;   a plurality of through holes which are formed around a side surface of the cylinder of the inner drum and in the other end surface of the cylinder in the axial direction and from which water is discharged during the washing and through which circulation air for drying circulates during the drying;   blowing means for blowing, into the storage chamber, air for drying heated by heating means during the drying; and   blowing regulation means for blowing the air for drying into the storage chamber from the side of one end or the other end of the cylinder of the inner drum in the axial direction, allowing the air to flow from the through holes on the other end side or from the one end side, and inhibiting outflow of the air for drying from the other through holes.   
   
   
       2 . The washing and drying machine according to  claim 1 , wherein a partition wall which divides a space between the outer drum and the inner drum into the one-end side or the other-end side from which the air for drying flows and another part constitutes the blowing regulation means. 
   
   
       3 . The washing and drying machine according to  claim 1 , wherein an opening/closing member which openably closes the through holes around the side surface of the inner drum constitutes the blowing regulation means, and the opening/closing member opens the through holes during the washing, and closes the through holes during the drying. 
   
   
       4 . The washing and drying machine according to any one of  claims 1  to  3 , further comprising:
 a refrigerant circuit in which at least a compressor, a radiator, a pressure reduction device and an evaporator are successively connected in an annular form via pipes,   wherein the radiator constitutes the heating means, the air for drying subjected to heat exchange between the air and the radiator is blown into the storage chamber during the drying, and the air blown through the storage chamber is subjected to heat exchange between the air and the evaporator.
