Blower

Abstract

A blower may include a lower case having a suction port, a fan provided inside the lower case, an upper case provided above the lower case and having a space through which air blown from the fan flows, a discharge port penetrating the upper case and formed to be elongated, and a flow guide provided in the space and extending in a direction crossing a longitudinal direction of the discharge port.

1 . A blower, comprising:
 a lower case having a suction port;   a first tower disposed above the lower case, having a first distribution space formed inside the first tower, and having a first discharge port;   a second tower disposed above the lower case, having a second distribution space formed inside the second tower, having a second discharge port, and spaced apart from the first tower;   a blowing space formed between the first tower and the second tower; and   a heater disposed in at least one of the first and second distribution spaces,   wherein the first tower comprises:   a first inner wall facing the blowing space and in which the first discharge port is disposed; and   a first outer wall being opposite to the first inner wall with respect to the first distribution space, being convex in a direction opposite to the first inner wall, and having a greater curvature than the first inner wall,   wherein the second tower comprises:   a second inner wall facing the blowing space and in which the second discharge port is disposed; and   a second outer wall being opposite to the second inner wall with respect to the second distribution space, being convex in a direction opposite to the second inner wall, and having a greater curvature than the second inner wall, and   wherein the heater is extended in an up-down direction and is inclined with respect to the vertical axis (Z).   
     
     
         2 . The blower of  claim 1 , wherein the blowing space is opened in a front-rear direction,
 wherein the first discharge port is positioned closer to a rear end of the first tower than to a front end of the first tower, is extended along a longitudinal direction of the heater, and is inclined with respect to the vertical axis (Z), and   wherein the second discharge port is positioned closer to a rear end of the second tower than to a front end of the second tower, is extended along the longitudinal direction of the heater, and is inclined with respect to the vertical axis (Z).   
     
     
         3 . The blower of  claim 2 , wherein the heater comprises a first heater disposed in the first distribution space and parallel to the first discharge port. 
     
     
         4 . The blower of  claim 2 , wherein an upper end of the heater is positioned at the center of the first or second distribution space in the front-rear direction, and a lower end of the heater is positioned closer to the rear end of the first or second tower than to the front end of the first or second tower. 
     
     
         5 . The blower of  claim 2 , wherein the heater is positioned in front of at least one of the first and second discharge ports,
 wherein the first discharge port is positioned adjacent to the rear end of the first inner wall, and   wherein the second discharge port is positioned adjacent to the rear end of the second inner wall.   
     
     
         6 . The blower of  claim 3 , wherein the heater further comprises a second heater disposed in the second distribution space and parallel to the second discharge port. 
     
     
         7 . The blower of  claim 2 , further comprising a flow guide positioned in at least one of the first and second distribution spaces, and extending in a direction that intersects a longitudinal direction of the first or second discharge port. 
     
     
         8 . The blower of  claim 7 , wherein the flow guide comprises a plurality of flow guides spaced apart from and aligned with each other in the longitudinal direction of the first or second discharge port. 
     
     
         9 . The blower of  claim 2 , wherein the rear ends of the first and second towers extend upwardly and forwardly, and
 wherein the front ends of the first and second towers extend upwardly and rearwardly.   
     
     
         10 . The blower of  claim 9 , wherein the first discharge port extends along the rear end of the first tower, and
 wherein the second discharge port extends along the rear end of the second tower.   
     
     
         11 . The blower of  claim 1 , further comprising:
 a board guide disposed in at least one of the first and second distribution spaces so as to be movable in the up-down direction, and having a guide slit extending obliquely with respect to the vertical axis (Z); and   a board disposed in at least one of the first and second distribution spaces and movably coupled to the guide slit,   wherein the blowing space is opened in a front-rear direction,   wherein the first tower further comprises a first board slit positioned in front of the first discharge port and extending in the up-down direction,   wherein the second tower further comprises a second board slit positioned in front of the second discharge port and extending in the up-down direction, and   wherein, when the board guide moves in the up-down direction, the board moves forward toward the first or second board slit.   
     
     
         12 . The blower of  claim 11 , wherein the board includes a guide protrusion protruding toward the guide slit and inserted into the guide slit, and
 wherein, when the board guide moves in the up-down direction, the guide protrusion moves along the guide slit.   
     
     
         13 . The blower of  claim 11 , further comprising a cover configured to support the board guide and to guide the movement of the board guide. 
     
     
         14 . The blower of  claim 1 , further comprising a first airflow converter that is movably positioned at the first distribution space so that the first airflow converter protrudes from the first distribution space into the blowing space; and
 a second airflow converter that is movably positioned at the second distribution space so that the second airflow converter protrudes from the second distribution space into the blowing space.
