The heat exchanger 130 may be disposed between the blower fan 140 and the receiving wall 112 to exchange heat between the refrigerant flowing in the heat exchanger 130 and the air discharged from the blower fan 140. . For example, the heat exchanger 130 may be a fin tube type heat exchanger using a fin and a refrigerant tube of a plurality of bent shapes. On the other hand, in the present disclosure, it should be noted that the type of heat exchanger 130 is not limited. The heat exchanger 130 may be formed in a cylindrical shape as schematically shown in FIG.

The blowing fan 140 may be disposed inside the housing 110 and discharge air sucked into the center in the circumferential direction.

The cover integrated drain plate 150 is a passage of air circulated inside the housing 110, and functions as a cover member surrounding the housing 110, and collects condensed water falling from the heat exchanger 130 to be discharged to the outside. have. The cover integrated drain plate 150 is formed at the center and is formed at an inlet 154 for guiding the air in the indoor space 3 to the blower fan 140, and is formed outside the inlet 154 and from the blower fan 140. It may include a discharge port 155 for guiding the discharged air to the indoor space (3). The discharge port 155 may have a donut shape having a diameter larger than that of the heat exchanger 130. The discharge holes 155 may be completely overlapped in the vertical direction with respect to the discharge guide 173, as shown in FIGS. 3, 7, 8, 11A, and 13.

On the other hand, the ceiling wall 1 includes a plurality of finishing materials having a generally rectangular plate shape. In this case, the finishing member 160 may be formed to have the same area as the finishing material. In addition, the lateral area of the housing 110 may be smaller than that of the finishing member 160. According to such a shape, the air conditioning facility can be easily installed without damaging the external appearance of the ceiling wall 1 by simply removing the finishing material of one of the ceiling walls 1, and installing the ceiling type air conditioner 10. As shown in FIG. The closing member 160 may include an air inflow passage 161 corresponding to the maximum diameter of the discharge port 155.

The guide member 170 may uniformly guide the air discharged from the discharge port 155 to the indoor space 3. The guide member 170 includes an intake wall 172 forming an intake passage 171 for guiding the air flowing into the inlet 154, and a discharge guide 173 extending in the circumferential direction from the intake wall 172. can do. The discharge guide 173 may have a shape inclined downward toward the outside from the center of the guide member 170. Here, the inclined shape does not necessarily have to be flat. For example, the discharge guide 173 may include a curved surface recessed downward as shown in FIG. 7. According to the discharge guide 173, the air discharged from the discharge port 155 may be discharged in all directions of 360 degrees. The guide member 170 may completely overlap in the vertical direction with respect to the closure member 160, as shown in FIGS. 1, 2, 3, 7 to 9, and 11a.

The filter 180 is disposed in the suction passage 171 and may purify the air introduced into the housing 110 through the suction passage 171. The filter 180 may be circular, for example, to correspond to the shape of the suction passage 171.

4 is a bottom view of a housing according to another embodiment of the present disclosure. Referring to FIG. 4, a housing 110 according to another embodiment of the present disclosure may include a flow guide 125. In other words, the flow guide 125 may protrude from the base 111 of the housing 110 instead of being formed on the separator plate 120. In this case, the minimum length R1 from the center of the base 111 to the flow guide 125 is larger than the maximum length R2 from the rotation center of the blower fan 140 to the auxiliary blade 142 (see FIG. 5). It can be long.

On the other hand, the flow guide 125 may be provided in the separation plate 120 and the housing 110, respectively. The flow guide 125 will be described in more detail with reference to FIGS. 7 and 8.

5 is a perspective view of a blowing fan according to an embodiment of the present disclosure. Referring to FIG. 5, the blower fan 140 according to an exemplary embodiment of the present disclosure may include a main blade 141, an auxiliary blade 142 disposed above the main blade 141, a main blade 141, and an auxiliary blade. It may include an intermediate plate 143 formed between the blades 142. The function of each blade and intermediate plate 143 will be described in more detail with reference to FIGS. 7 and 8.

6A is a perspective view of a cover integrated drain plate according to an exemplary embodiment of the present disclosure, and FIG. 6B is a cross-sectional view taken along the cut line I-I of FIG. 6A.

6A and 6B, the cover-integrated drain plate 150 according to the embodiment of the present disclosure includes: a drain groove 151 for collecting condensed water falling from the heat exchanger 130 and a drain groove 151. A condensate discharge passage 152 for guiding condensate collected and communicated to the outside, a housing fastening portion 153 coupled to the housing 110, and an inlet 154 for guiding air introduced into the blower fan 140. And a discharge port 155 for guiding the air discharged from the blower fan 140 and a discharge vane 156 installed in the discharge port 155 to control the discharge direction of the air.

The cover integrated drain plate 150 may be formed of, for example, a transparent material. If the cover-integrated drain plate 150 is made of a transparent material, it is possible to easily check the contamination state of the drain groove 151, the inlet 154, and the outlet 155 which are most likely to be contaminated without removing the ceiling type air conditioner 10. In addition, maintenance costs can be saved due to unnecessary service requests. In addition, since contamination can be checked from time to time, if contamination is found, it can be quickly requested for replacement or repair, thereby improving the cleanliness of the air conditioner 10.

The housing fastening part 153 of the cover integrated drain plate 150 may be detachably provided to the housing 110. The cover integrated drain plate 150 may include a latch portion 1531 that is fastened to the first fastening means 113 in a snap manner. According to this structure, the drain groove 151, the suction port 154 and the discharge port 155 can be cleaned and / or replaced by simply removing the cover-integrated drain plate 150 from the housing 110. The effort and cost of repair work can be saved.

The portion close to the condensate discharge passage 152 in the drain groove 151 may be formed lower than the remaining portion. For example, the drain groove 151 may be formed to be inclined downward toward the condensate discharge passage 152. According to such a structure, since the water accommodated in the drain groove 151 can be naturally induced into the condensate discharge flow path 152 by gravity and discharged to the outside, water can be prevented from remaining in the drain groove 151. .

7 is a view showing the internal structure of the ceiling air conditioner according to an embodiment of the present disclosure, Figure 8 is a view showing the air flow of the ceiling air conditioner according to an embodiment of the present disclosure.

7 and 8, at least a portion of the main blade 141 of the blowing fan 140 may be disposed to overlap the heat exchanger 130 in the circumferential direction from the rotation center of the blowing fan 140. For example, as shown in FIGS. 7 and 8, the entirety of the main blade 141 may overlap the heat exchanger 130.

At least a part of the auxiliary blade 142 of the blowing fan 140 may be disposed so as not to overlap with the heat exchanger 130 in the circumferential direction from the rotation center of the blowing fan 140. For example, as illustrated in FIGS. 7 and 8, one half or more of the auxiliary blades 142 may not overlap with the heat exchanger 130.

According to such a structure, the first air stream discharged by the main blade 141 is heat-exchanged while passing through the heat exchanger 130, and passes through the space between the receiving wall 112 and the heat exchanger 130 to discharge the outlet 155. Through the discharge guide 173 may be discharged to the indoor space.

Meanwhile, at least 1/2 of the second air stream discharged by the auxiliary blade 142 does not pass through the heat exchanger 130, but directly passes through a space formed between the receiving wall 112 and the heat exchanger 130. It may be discharged to the indoor space along the discharge guide 173 through the discharge port 155.

Since the heat exchange efficiency of the heat exchanger 130 is improved as the contact area is increased, the heat exchanger 130 has a structure for widening the contact area. Therefore, the kinetic energy may be reduced while the first air flow passes through the large contact area of the heat exchanger 130, thereby weakening the earth output. However, since the second airflow is directly discharged without passing through the heat exchanger 130, the second airflow may be more strongly discharged. In addition, since the second airflow flows into the corner portion where the base 111 and the receiving wall 112 abut, that is, the upstream side of the first airflow, the second airflow may serve to strongly push the first airflow.

In addition, since the second airflow helps the rapid circulation of air, condensation generated in the housing 110 such as the heat exchanger 130 may be reduced as the air of high humidity moves slowly around the heat exchanger 130. have.

On the other hand, low pressure may be formed on the flow path of the second air stream by the high flow rate of the second air stream. In this case, it may cause air on the flow path of the first air stream (ie, air heat exchanged by the heat exchanger 130) in the high pressure state at a relatively slow flow rate to be introduced into the flow path of the second air stream. . However, since the flow path of the first air flow and the flow path of the second air flow are partitioned from each other due to the intermediate plate 143 and the separation plate 120, the problem that thermal efficiency decreases as the flow path of the first air flow increases is prevented. can do. In other words, the intermediate plate 143 and the separator plate 120 may block the first air stream from moving upward. 7 and 8, the intermediate plate 143 and the separator plate 120 may be positioned at the same height.

On the other hand, the second air stream discharged by the auxiliary blade 142 may flow in a vortex while passing through the flow guide 125. According to such a structure, it is possible to prevent the second airflow from being discharged in the direction perpendicular to the receiving wall 112, and to prevent the kinetic energy of the airflow from weakening due to the sudden change of the flow path. In addition, according to the vortex-shaped flow of the second air stream, it is possible to prevent the problem that the discharge air revolves around the corner portion where the base 111 and the receiving wall 112 are in contact with each other. On the other hand, in order to smoothly guide the flow of air in the corner portion, the corner portion may have a curved shape.

Meanwhile, the cover integrated drain plate 150 includes a coupling outer wall 157 and a coupling inner wall 158 extending downward, and the passage wall of the closure member 160 and the intake wall 172 of the guide member 170 are It may be coupled to the coupling outer wall 157 and the coupling inner wall 158, respectively. However, this is only one example, and in the embodiment of the present disclosure, the coupling form of the closing member 160 and the guide member 170 is not necessarily limited thereto.

9 is a bottom view of a ceiling type air conditioner according to an embodiment of the present disclosure. Referring to FIG. 9, the ceiling type air conditioner 10 according to the exemplary embodiment of the present disclosure may discharge air radially as shown in FIG. 9. In other words, the ceiling type air conditioner 10 may uniformly discharge air at 360 degrees so that there is no blind spot of air conditioning. Due to the characteristics of the air discharge direction of the ceiling type air conditioner 10, by installing the ceiling type air conditioner 10 in the center of the ceiling, it is possible to balance the air conditioner distribution of the indoor space. According to such a structure, the problem of the unbalance of air-conditioning distribution can be eliminated compared with the other air-conditioning apparatus suitably installed in the side wall of an indoor space.

FIG. 10A is a top perspective view of a cover integrated drain plate according to another embodiment of the present disclosure, and FIG. 10B is a bottom perspective view of a cover integrated drain plate according to another embodiment of the present disclosure, and FIG. 11A is a view of another embodiment of the present disclosure. 11 is a bottom view of the ceiling type air conditioner, and FIG. 11B is a view showing the air flow when the ceiling type air conditioner according to another embodiment of the present disclosure operates.

10A to 11B, the cover-integrated drain plate 250 of the ceiling type air conditioner 20 according to another embodiment of the present disclosure is disposed in the discharge port 255 and the rotational force of the air discharged from the discharge port 255. It may include a discharge vane (256) for raising the. For example, the discharge vane 256 may be inclined downward along the circumferential direction so that the discharged air may have a vortex shape as shown in FIG. 11. According to such a structure, the indoor air can be more uniformly harmonized by assisting the mixing action of the indoor air.

12 is a view showing a cross-sectional view of a guide member according to another embodiment of the present disclosure, Figure 13 is a view showing a bottom view of the window is removed from the guide member according to another embodiment of the present disclosure.

12 and 13, the guide member 170 according to another embodiment of the present disclosure may further include an illumination unit 175 for illuminating the room. The lighting unit 175 may be disposed in a circular shape along the outside of the suction passage 171, for example. In order to secure even lighting, it is common to install a lighting device in the center of the ceiling, so it may be difficult to install the ceiling type air conditioner 10 in the center of the ceiling. However, in the case of the ceiling type air conditioner 10 having the lighting unit 175 as in another embodiment of the present disclosure, such a problem can be solved. According to another embodiment of the present disclosure, one ceiling type air conditioner 10 including the lighting device may be installed without separately installing the lighting device and the air conditioner in the indoor space.

For example, the lighting unit 175 may include a substrate 1751, a light source 1702, and a window 1753. The substrate 1751 may be disposed along the outer circumference of the intake wall 172 in a donut shape.

The light source 1702 may include, for example, a plurality of light emitting diodes (LEDs) provided on the substrate 1701. For example, the light sources 1702 may be arranged in a plurality of rows radially. When the ceiling type air conditioner 10 is installed at the center of the ceiling, the plurality of light sources 1702 may be arranged to be symmetrical with respect to the center of the guide member 170 in order to secure even indoor lighting. On the other hand, according to the installation position of the ceiling-type air conditioner 10, the light source 1702 may be arranged in an asymmetrical shape with respect to the center of the guide member 170.
