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 to provide an inner space, and the case having an inlet; a first body provided above the case; and a fan configured to suction air through the inlet and to discharge air into the first body; wherein the first body includes a first wall configured to provide a first flow path for communicating with the inner space of the case, and a first panel configured to accommodate the first wall within the first panel, wherein the first panel includes a first slit configured to discharge air from the first flow path to an outside of the first panel.

2 . The blower of claim 1 , further comprising:
a second body provided above the case and spaced apart from the first body to provide a blowing space between the first body and the second body, the second body including a second wall configured to provide a second flow path for communicating with the inner space of the case, and a second panel to accommodate the second wall within the second panel, wherein the second panel includes a second slit configured to discharge air from the second flow path to an outside of the second panel.

3 . The blower of claim 2 , wherein the first panel comprises:
a first inner panel provided on one side of the first wall to face the blowing space and to provide the first slit; and a first outer panel provided on an opposite side of the first wall, the first outer panel to contact the first inner panel and provide a first front end and a first rear end of the first body, wherein the second panel comprises:
a second inner panel provided on one side of the second wall to face the blowing space and to provide the second slit; and
a second outer panel provided on an opposite side of the second wall, the second outer panel to contact the second inner panel and provide a second front end and a second rear end of the second body, and
wherein the blowing space is provided between the first inner panel and the second inner panel.

4 . The blower of claim 3 , wherein the first body is spaced from the second body in a first direction,
wherein the first inner panel is to have a convex shape in a second direction which is opposite to the first direction, wherein the first outer panel is to have a convex shape in the first direction, wherein the second inner panel is to have a convex shape in the first direction, wherein the second outer panel is to have a convex shape in the left direction, wherein a curvature of the first inner panel is less than a curvature of the first outer panel, wherein a curvature of the second inner panel is less than a curvature of the second outer panel, and wherein a gap of the blowing space between the first inner panel and the second inner panel is to decrease from a rear of the blowing space to a center of the blowing space, and the gap of the blowing space is to increase from the center of the blowing space to a front of the blowing space.

5 . The blower of claim 1 , wherein the first body includes a first opening configured to communicate with the first flow path and having an outlet corresponding to the first slit.

6 . The blower of claim 5 , wherein the first panel includes:
a first bending portion that is bent toward the first flow path; a first guide portion to connect to the first bending portion in a front of the first bending portion; and, a first inlet portion that is spaced apart, in a rearward direction, from the first bending portion, wherein the first slit is provided between the first bending portion and the first inlet portion.

7 . The blower of claim 6 , wherein the first wall has a first end adjacent to the first guide portion, and a second end spaced apart from the first end and connected to the first inlet portion,
wherein at least a portion of the first bending portion is provided between the first end of the first wall and the second end of the first wall, wherein the first body includes a first connecting member provided between the first end of the first wall and the first bending portion, and the first connecting member is connected to the second end of the first wall and the first bending portion, and wherein the first opening is provided between the first connecting member and the first bending portion, and the first wall and the first inlet portion.

8 . The blower of claim 7 , wherein a first end of the first connecting member is provided between the first wall and the first guide portion,
wherein a second end of the first connecting member is connected to an end of the first bending portion, wherein the first connecting member includes: a first portion configured to provide the first end of the first connecting member; a second portion bent from the first portion toward the first opening; and a third portion to extend from the second portion toward the first bending portion and to provide the second end of the first connecting member.

9 . The blower of claim 8 , wherein the second end of the first wall is connected to an inside of the first inlet portion,
wherein the first inlet portion includes a front portion to protrude from the second end of the first wall toward the first bending portion and having an inner surface facing the third portion, and wherein the first opening is provided between the second portion, the third portion and the first bending portion, and the first wall and the front portion.

10 . The blower of claim 9 , wherein a gap between the second portion and the first wall is constant or becomes smaller toward a downstream of the first opening.

11 . The blower of claim 9 , wherein a gap between the third portion and the front portion is constant or becomes smaller toward a downstream of the first opening.

12 . The blower of claim 9 , wherein the first body includes a groove provided in at least one of the third portion and the first bending portion and facing an inner surface of the front portion.

13 . The blower of claim 9 , wherein the first body includes a spacer to couple to the first bending portion and to the first inlet portion, and the spacer is provided between the first bending portion and the front portion, and
wherein a thickness of the front portion is increased as it is adjacent to the spacer.

14 . The blower of claim 7 , wherein the first connecting member includes a first hook to hook couple to a first locking part at the first wall.

15 . The blower of claim 14 , wherein the first bending portion includes a second hook to hook couple to a second locking part at the first connecting member.

16 . The blower of claim 1 , wherein the first flow path is elongated in an up-down direction,
wherein the first slit is provided at a rear of the first panel, wherein the first body includes a first vane provided in the first flow path adjacent to the first slit, and the first vane is to have a convex upward shape, and wherein a rear of the first vane is above a front of the first vane.
