Air conditioner

Abstract

An air conditioner includes a main body that includes a suction port and an outlet port, wherein: the main body includes a front surface, a back surface, an upper surface, a lower surface, and a pair of side surfaces; the suction port is formed on any of the front surface, the upper surface, and the side surfaces; the outlet port is formed on at least the lower surface; an outlet air channel is upstream from the outlet port; a side of the outlet air channel near the front surface is formed by a diffuser; and the diffuser includes a portion that diverges from an imaginary straight line that constitutes a direction of extension of an upstream portion of the diffuser increasingly toward a downstream end of the diffuser in a side view.

         10 . An air conditioner comprising:
 a main body that comprises a suction port and an outlet port;   a blowing portion that is disposed inside said main body; and   a heat exchanging portion that is disposed inside said main body,   wherein:   said main body includes a front surface, a back surface, an upper surface, a lower surface, and a pair of side surfaces;   said suction port is formed on any of said front surface, said upper surface, and said side surfaces;   said outlet port is formed on at least said lower surface;   an outlet air channel is upstream from said outlet port;   a side of said outlet air channel near said front surface is delimited by a diffuser;   said diffuser comprises a portion that diverges from an upstream portion imaginary straight line that constitutes a direction of extension of an upstream portion of said diffuser increasingly toward a downstream end of said diffuser when viewed from a side;   a stabilizer is disposed below said heat exchanging portion, said diffuser being formed on a lower surface of said stabilizer;   said suction port is formed on said front surface of said main body and being disposed within a range that is lower than an upper end of said blowing portion and higher than an upper end of said stabilizer in a height direction of said main body;   an airflow guiding wall is disposed downstream from said suction port; and   said airflow guiding wall has an L-shaped cross section comprising:
 a horizontal surface that extends horizontally toward a back surface side of said main body; and 
 a downward surface that extends downward. 
   
     
     
         11 . The air conditioner according to  claim 10 , wherein said outlet port is formed so as to span said front surface and said lower surface. 
     
     
         12 . The air conditioner according to  claim 10 , wherein:
 a vertical wind directing vane that adjusts a vertical component of direction of expulsion of air that is blown out from said blowing portion is disposed in said outlet air channel; and   a length of a rectilinear portion of a downstream portion of said diffuser is a length that is greater than or equal to half of a length of a chord that joins an upstream end and a downstream end of said vertical wind directing vane when viewed from a side.   
     
     
         13 . The air conditioner according to  claim 10 , wherein:
 a side of said outlet air channel near said back surface is delimited by a guiding wall, said outlet air channel being configured by said diffuser and said guiding wall, which face each other.   
     
     
         14 . The air conditioner according to  claim 13 , wherein a distance between an upstream portion of said diffuser and a downstream portion of said guiding wall widens toward a downstream end. 
     
     
         15 . The air conditioner according to  claim 10 , wherein an angle α that is formed between an upstream portion imaginary straight line S 1  and a downstream portion imaginary straight line S 2  is 5 degrees through 40 degrees when viewed from a side, where said upstream portion imaginary straight line S 1  is a direction of extension of a rectilinear portion of an upstream portion of said diffuser and said downstream portion imaginary straight line S 2  is a direction of extension of a rectilinear portion of a downstream portion of said diffuser. 
     
     
         16 . The air conditioner according to  claim 10 , wherein said suction port is formed on said front surface of said main body and has an opening that has a length that corresponds to a length in a width direction of at least said heat exchanging portion.
