Drum type washing and drying machine

Abstract

A drum type washing and drying machine includes a cylindrical rotary drum provided with drum perforations and having a rotating shaft in a horizontal or a slanted direction; a water tub, supported in a main body of the drum type washing and drying machine, for accommodating therein the rotary drum; a dehumidification unit for dehumidifying air exhausted from the rotary drum via the water tub; and a blower-heater path communicating with the dehumidification unit and incorporating therein a blower and a heater. The washing and drying machine is also provided with a circulation path for allowing the blower-heater path and the rotary drum to communicate with each other via the water tub. An opening sealing member is installed at a connection opening between the blower-heater path and circulation path such that the opening sealing member is disposed to be rotable in conjunction with an operation of the blower.

1 . A drum type washing and drying machine comprising: 
 a cylindrical rotary drum provided with multiple drum perforations on a cylindrical surface thereof and having a rotating shaft in a horizontal or a slanted direction;    a water tub, elastically supported in a main body of the drum type washing and drying machine, for accommodating therein the rotary drum;    a dehumidification unit for dehumidifying air exhausted from the rotary drum via the water tub;    a blower-heater path communicating with the dehumidification unit and incorporating therein a blower and a heater;    a circulation path for allowing the blower-heater path and the rotary drum to communicate with each other via the water tub; and    an opening sealing member installed at a connection opening provided between the blower-heater path and circulation path, the opening sealing member being rotable in conjunction with an operation of the blower.    
   
   
       2 . The machine of  claim 1 , wherein the opening sealing member has a rotation axis which divides the opening sealing member into a left and a right portion, and a weight balance between the left and the right portion with respect to the rotation axis is maintained such that the opening sealing member closes the connection opening while the blower is stopped, and opens the connection opening by making a rotation when the blower is operated.  
   
   
       3 . The machine of  claim 1 , wherein the opening sealing member has a rotation axis, and facing surfaces of the connection opening and the opening sealing member in an axial direction of the rotation axis are formed to have substantially planar shapes.  
   
   
       4 . The machine of  claim 1 , wherein the opening sealing member has a rotation axis which divides the opening sealing member into a left and a right portion having different areas.  
   
   
       5 . The machine of  claim 1 , wherein the opening sealing member has a rotation axis which divides the opening sealing member into a left and a right portion, and a weight is disposed in either one of the left and the right portion.
