Washing-drying machine

Abstract

The present disclosure provides a washing-drying machine. The washing-drying machine includes: a cabinet; an inner drum rotatably disposed in the cabinet and defines an accommodating cavity therein, in which the inner drum has an air outlet communicated with the accommodating cavity and a condensation air channel disposed in a bottom wall thereof, the condensation air channel is communicated with the accommodating cavity and the air outlet respectively; and a heat exchanger disposed in the cabinet and configured to exchange heat with wet air in the condensation air channel.

What is claimed is: 
     
         1 . A washing-drying machine, comprising:
 a cabinet;   an inner drum rotatably disposed in the cabinet and defines an accommodating cavity therein, wherein the inner drum has an air outlet communicated with the accommodating cavity and a condensation air channel disposed in a bottom wall thereof, the condensation air channel is communicated with the accommodating cavity and the air outlet respectively; and   a heat exchanger disposed in the cabinet and configured to exchange heat with wet air in the condensation air channel.   
     
     
         2 . The washing-drying machine according to  claim 1 , further comprising an air channel cover plate, wherein the air channel cover plate is connected with the bottom wall of the inner drum to define the condensation air channel. 
     
     
         3 . The washing-drying machine according to  claim 2 , wherein the bottom wall of the inner drum is provided with a relief groove protruding outwards along an axial direction of the inner drum, the relief groove is communicated with the air outlet, and the air channel cover plate is fitted with the relief groove to define the condensation air channel. 
     
     
         4 . The washing-drying machine according to  claim 3 , wherein the condensation air channel has an air channel inlet communicated with the accommodating cavity and the condensation air channel respectively. 
     
     
         5 . The washing-drying machine according to  claim 4 , wherein the air channel inlet is formed at an end of the condensation air channel. 
     
     
         6 . The washing-drying machine according to  claim 5 , wherein a projected area of the air channel cover plate on a plane vertical to the axial direction of the inner drum is smaller than a projected area of the relief groove on the plane, so as to define the air channel inlet. 
     
     
         7 . The washing-drying machine according to  claim 2 , wherein the air channel cover plate is connected with the inner drum by a bolt. 
     
     
         8 . The washing-drying machine according to  claim 2 , wherein the air channel cover plate is connected with the inner drum adhesively. 
     
     
         9 . The washing-drying machine according to  claim 2 , wherein the air channel cover plate is flush with the bottom wall of the inner drum. 
     
     
         10 . The washing-drying machine according to  claim 3 , wherein the relief groove is formed integrally when the inner drum is molded.
