Ceiling-type air conditioner

Abstract

Disclosed herein is a ceiling-type air conditioner including: an upper housing having a cylindrical shape, a heat exchanger having in an annular shape and disposed inside the upper housing, a blowing fan disposed on the inside of the heat exchanger and configured to draw in air and heat exchange the drawn-in air with the heat exchanger. In addition, the ceiling-type air conditioner may include a lower housing including an outlet disposed on a radially outer side of the heat exchanger and configured to discharge the heat exchanged air to the outside of the upper housing and having an annular shape and an inlet panel through which external air is drawn in by the blowing fan, the lower housing movable in a vertical direction between a first position and a second position different from the first position, and a middle housing disposed between the upper housing and the lower housing and including a plurality of discharge holes disposed outside the outlet in a radial direction of the lower housing, wherein the lower housing is configured to open the outlet when placed in the first position, and to close the outlet when placed in the second position, so that the air heat exchanged with the heat exchanger is discharged through the plurality of discharge holes.

What is claimed is: 
     
         1 . A ceiling-type air conditioner, comprising:
 an upper housing having a cylindrical shape;   a heat exchanger having in an annular shape disposed inside the upper housing;   a blowing fan disposed on an inside of the heat exchanger and configured to draw in air and heat exchange the drawn-in air with the heat exchanger;   an outlet disposed on a radially outer side of the heat exchanger and configured to discharge the heat exchanged air to the outside of the upper housing, the outlet having an annular shape;   a lower housing including an inlet panel through which external air is configured to be drawn in by the blowing fan, and movable in a vertical direction between a first position and a second position different from the first position; and   a middle housing disposed between the upper housing and the lower housing and including a plurality of discharge holes disposed outside the outlet in a radial direction of the lower housing;   wherein the lower housing is configured to open the outlet based on being placed in the first position, and to open the outlet based on being placed in the second position, so that the air heat exchanged with the heat exchanger is discharged through the plurality of discharge holes.   
     
     
         2 . The ceiling-type air conditioner of  claim 1 , wherein the lower housing is movable vertically between the first position and the second position, the first position being on a lower side of the second position. 
     
     
         3 . The ceiling-type air conditioner of  claim 1 , wherein the middle housing includes:
 a discharge base in which the plurality of discharge holes is formed, and   a divider extending upwardly from the discharge base to separate a flow path through which airflow discharged through the outlet is configured to flow, and a flow path through which airflow discharged through the plurality of discharge holes is configured to flow.   
     
     
         4 . The ceiling-type air conditioner of  claim 3 , wherein the divider includes a plurality of distribution ports configured to direct the air heat exchanged from the heat exchanger to the flow path through which the airflow discharged through the plurality of discharge holes is configured to flow. 
     
     
         5 . The ceiling-type air conditioner of  claim 4 , further comprising an open/close member comprising a door configured to open the plurality of distribution ports based on the lower housing being in the second position, and to close the plurality of distribution ports based on the lower housing being in the first position. 
     
     
         6 . The ceiling-type air conditioner of  claim 5 , wherein the open/close member is hinge-coupled to the divider. 
     
     
         7 . The ceiling-type air conditioner of  claim 5 , wherein the open/close member extends vertically and is configured to be slidable in an up and down direction. 
     
     
         8 . The ceiling-type air conditioner of  claim 3 , wherein the lower housing includes a guide surface inclined to face the middle housing, wherein a first discharge airflow discharged through the outlet is configured to be guided radially outwardly of the upper housing by the guide surface. 
     
     
         9 . The ceiling-type air conditioner of  claim 8 , wherein the discharge base has a downward convex shape , and a second discharge airflow discharged through the plurality of discharge holes is configured to be discharged wider than the first discharge airflow. 
     
     
         10 . The ceiling-type air conditioner of  claim 4 , further comprising a guide disposed between the middle housing and the upper housing and configured to guide the air passing through the plurality of distribution ports to the plurality of discharge holes. 
     
     
         11 . The ceiling-type air conditioner of  claim 10 , wherein the guide extends from the divider to the discharge base and is configured to separate a flow path through which the airflow flowing through the plurality of distribution ports and toward the plurality of discharge holes flows. 
     
     
         12 . The ceiling-type air conditioner of  claim 11 , wherein the guide is provided in a plurality and spaced apart from each other and configured to distribute the airflow passing through the plurality of distribution ports to a radially outer side of the upper housing. 
     
     
         13 . The ceiling-type air conditioner of  claim 1 , wherein based on the lower housing being placed in a third position between the first position and the second position, the airflow discharged through the outlet is configured to be discharged downwardly, and
 the airflow discharged through the plurality of discharge holes is configured to be discharged to a radially outer side of the upper housing.   
     
     
         14 . The ceiling-type air conditioner of  claim 1 , wherein the outlet is disposed between the lower housing and the middle housing, and based on the lower housing being placed in the second position, the lower housing and the middle housing meet and close the outlet. 
     
     
         15 . The ceiling-type air conditioner of  claim 1 , wherein the upper housing includes an insulation covering an outer circumferential surface of the upper housing adjacent to the plurality of discharge holes.
