Abstract

A blower is provided. The blower according to the present disclosure includes: a fan causing airflow; a lower body forming an inner space at which the fan is disposed, and having a suction hole through which air passes; and a first upper body positioned above the lower body, and the first upper body may include a first wall forming a first flow path communicating with the inner space of the lower body and a first panel surrounding the first wall, and the first panel may include a first slit formed through the first panel and discharging air flowing through the first flow path to an outside of the first panel.

First claim

What is claimed is:

1. A blower comprising:
a case having a suction hole;
a fan disposed in the case and discharging upwardly an air introduced through the suction hole;
a first tower disposed above the case, forming a first flow path communicating with an inner space of a lower body, and including a first slit;
a second tower disposed above the case, forming a second flow path communicating with the inner space of the lower body, including a second slit, and laterally spaced apart from the first tower;
a blowing space formed between the first and second towers, opened in a front-rear direction, and in which discharged air from the first and second slits flows;
wherein the first tower includes:
a first inner part facing the blowing space, extending in the front-rear direction, in which the first slit is disposed, and
a first outer part being opposite to the first inner part,
wherein the second tower includes:
a second inner part facing the blowing space, extending in the front-rear direction, in which the second slit is disposed, and
a second outer part being opposite to the second inner part,
wherein the first and second slits are disposed adjacent to a rear end of the first and second inner part,
wherein each of the first and second towers includes:
a turning passage having an inlet communicating with the first or second flow path, having an outlet forming the first or second slit, and having a rounded shape such that airflow flowing within the first or second flow path is turned to a frontward direction; and
a turning part protruding from the first or second inner part, and spaced apart from the first or second outer part to form the turning passage therebetween, and
wherein the turning part is protruded obliquely from the first or second inner part to a rearward direction.

2. The blower of claim 1 , wherein each of the first and second towers includes:
an inner panel providing an outer surface of the first and second inner part;
an inner wall providing an inner surface of the first and second inner part;
an outer panel providing an outer surface of the first and second outer part; and
an outer wall providing an inner surface of the first and second outer part, and
wherein the first and second slits are formed by penetrating the inner panel,
wherein the inner wall is opened in correspond to the inner panel, and
wherein the turning part includes a connecting member that connects an end portion of the inner panel disposed front of the first or second slit and an end portion of the inner wall disposed front of the turning passage.

3. The blower of claim 1 , wherein a width of the turning passage is being narrower or constant respect to an airflow direction.

4. The blower of claim 1 , wherein an outer surface of the turning part and an inner surface of the first and second outer parts provide a boundary of the turning passage, and have round shape with a same center of curvature.

5. The blower of claim 1 , wherein each of the first and second outer parts includes: an outer panel providing an outer surface of the first and second outer part; and an outer wall providing an inner surface of the first and second outer part, and wherein the outer wall have a curved shape placing the turning part inside and being convex to an outward direction.

6. The blower of claim 5 , wherein the outer wall have a round shape from a front end of the outer wall to a rear end of the outer wall.

7. The blower of claim 1 , wherein each of the first and second inner parts is divided into an inlet part located behind and a guide part located in front with respect to the first and second slits, and wherein the guide part forms a slope oblique about the front-rear direction at an end portion adjacent to the first and second slits, and wherein the inlet part extends along an imaginary line extending the slope of the guide part.

8. The blower of claim 7 , wherein each of the first and second outer parts includes: an outer panel providing an outer surface of the first and second outer part; and
an outer wall providing an inner surface of the first and second outer part, and
wherein the outer panel is connected to a rear end of the inlet part such that forming a rear end of the first and second towers, and
wherein the outer wall is connected to a front end of the inlet part such that providing a boundary of the first and second flow paths.

9. The blower of claim 8 , wherein each of the rear end of the first and second towers has a pointed shape.

10. The blower of claim 9 , wherein each of the rear end of the first and second towers is disposed on the imaginary line.

11. The blower of claim 1 , wherein each of the first and second outer parts includes:
an outer panel providing an exterior of the first and second outer part; and
an outer wall providing an inner surface of the first and second outer part and providing a boundary of the first flow path, and
wherein the outer panel and the outer wall have different curvature to each other.

12. The blower of claim 11 , wherein a rear end of the outer panel is connected to the rear end of the first or second inner part, and wherein a rear end of the outer wall is connected to a portion of the first or second inner part adjacent to the first or second slit as being bent toward the first or second slit from the outer panel such that providing the boundary of the first or second turning passage in curved shape.

13. The blower of claim 12 , wherein each of the first and second towers includes:
a damper stored inside a storage space of the first or second tower, or being protrude through a slot to the blowing space such that change a direction of airflow of the blowing space, and
wherein the slot is disposed adjacent to a front end of the first or second inner part, and
wherein the storage space is formed between the outer panel and the outer wall.

14. The blower of claim 13 , wherein the outer wall includes:
a parallel portion extending along the outer panel;
a first bending portion bent inward from a rear end of the parallel portion and connected to the rear end of the first or second inner part; and
a second bending portion bent inward from a front end of the parallel portion and connected to the front end of the first or second inner part, and
wherein the first or second flow path is separated from the storage space by the second bending portion.

15. The blower of claim 14 , wherein the second bending portion includes a guide surface inclined toward the first or second slit with respect to a vertical axis (V) such that guides an air discharged from the fan toward the first or second slit.
