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 fan causing airflow; a lower body forming an inner space where the fan is disposed, and having a suction hole through which air passes; a first upper body positioned above the lower body; a second upper body spaced apart from the first upper body above the lower body; and a space formed between the first upper body and the second upper body and opened in a frontward-rearward direction; wherein each of the first and second upper bodies includes: an inner panel forming the exterior of the first and second upper bodies, and facing the space; an outer panel forming the exterior of the first and second upper bodies, and opposite the space with respect to the inner panel; an inner wall disposed between the inner panel and the outer panel; an outer wall disposed between the inner wall and the outer panel, and forming a flow path within the first and second upper bodies in conjunction with the inner wall; a slit formed to penetrate the inner panel, adjacent to a rear end of the first and second upper bodies, and configured to discharge air flowing through the flow path; and a connecting member connecting the rear end of the inner wall to one end of the inner panel forming a front end of the slit, extending in a rounded manner so that air flowing through the flow path turns forward and reaches the slit, wherein the connecting member protrudes toward an inner rear portion of the first and second upper bodies.

2 . The blower of claim 1 , wherein the inner panel includes:
a guide part forming a front portion of the slit; an inlet part forming a rear portion of the slit; and a bending part bent from a rear end of the guide part toward the flow path, wherein the inner wall is adjacent to the guide part and extends along the guide part, and wherein the connecting member connects the rear end of the inner wall to the bending part.

3 . The blower of claim 2 , wherein the outer panel connects to a front end of the guide part to form a front end of the first and second upper bodies, and the outer panel connects to a rear end of the inlet part to form a rear end of the first and second upper bodies, and the outer panel is convex on the opposite side of the space.

4 . The blower of claim 3 , wherein the outer wall is extended along a curvature of the outer panel from a front end of the outer wall, and the rear end of the outer wall is bent forward away from the outer panel, and the rear end of the outer wall is connected to the inner panel between the rear end and front end of the inlet part,
wherein a rear end portion of the outer wall is spaced apart from the connecting member, and wherein each of the first and second upper bodies includes an opening formed between the rear end portion of the outer wall and the connecting member, and wherein the opening is configured to allow the air flowing through the flow path to turn forward and reach the slit.

5 . The blower of claim 4 , wherein the connecting member includes:
a first part forming one end of the connecting member and connected to the inner wall; a third part forming the other end of the connecting member and connected to the bending part; and a second part connecting the first and third parts and curving along a curved surface formed at the rear end of the outer wall.

6 . The blower of claim 5 , wherein a first gap between one end of the second part connected to the first part and the rear end portion of the outer wall is the same as a second gap between the other end of the second part connected to the third part and the rear end portion of the other wall.

7 . The blower of claim 6 , wherein a third gap between one end of the third part connected to the bending part and a front part of the inlet part is smaller than the second gap.

8 . The blower of claim 4 , wherein the connecting member disposed such that one end of the connecting member is positioned between the rear end of the inner wall and the guide part, and the other end is in contact with one end of the bending part.

9 . The blower of claim 8 , wherein the connecting member includes:
a hook protruding toward the inner wall from one end of the connecting member and coupled to the rear end of the inner wall; and a locking part protruding toward the bending part between the one end and the other end of the connecting member and coupled to the bending part.

10 . The blower of claim 9 , wherein the locking part is spaced forward of the other end of the connecting member.

11 . The blower of claim 4 , wherein the inlet part includes a front part located forward of the point where the rear end of the outer wall is connected, and
the front part of the inlet part forms the opening in conjunction with the rear end of the outer wall.

12 . The blower of claim 11 , wherein the front part of the inlet part becomes thinner as it extends forward.

13 . The blower of claim 11 , wherein a front end of the inlet part forms a rear end of the slit.

14 . The blower of claim 3 , wherein the inner panels of the first and second upper bodies are convex toward the space, and
a gap between the inner panel of the first upper body and the inner panel of the second upper body decreases from the rear of the space toward the center of the space and increases from the center of the space toward the front of the space.

15 . The blower of claim 1 , wherein the inner wall and the outer wall of the first upper body are coupled at a position spaced rearward from a front end of the first upper body,
wherein the inner wall and the outer wall of the second upper body are coupled at a position spaced rearward from a front end of the second upper body, and wherein each of the first and second upper bodies includes: a first space separated from the flow path between the front end of the first upper body and the inner wall of the first upper body; and, a second space separated from the flow path between the front end of the second upper body and the inner wall of the second upper body.

16 . The blower of claim 15 , wherein the first upper body includes a first damper movably arranged in the first space to either protrude into the space or be received in the first space, the first damper changes the direction of the air flowing through the space,
wherein the first space is connected to a first slot formed in the inner panel of the first upper body, allowing the first damper to pass through the first slot and protrude into the space, wherein the second upper body includes a second damper movably arranged in the second space to either protrude into the space or be received in the second space, the second damper changes the direction of the air flowing through the space, and wherein the second space is connected to a second slot formed in the inner panel of the second upper body, allowing the second damper to pass through the second slot and protrude into the space.

17 . The blower of claim 8 , wherein the outer wall has a rounded shape extending from a rear end of the outer wall to a front end of the outer wall.
