Description

Air conditioner
Technical Field
The present invention relates to an air conditioner, and more particularly, to an air conditioner capable of reducing a flow separation phenomenon occurring in a suction portion of a blower fan.
Background
In general, in order to create a more comfortable indoor environment for a user, an air conditioner uses a refrigerating cycle of a refrigerant composed of a compressor, a condenser, an expansion mechanism, and an evaporator to cool and heat an indoor space or purify air.
Indoor units of air conditioners can be divided into a ceiling type, a wall type and a vertical type according to the installation positions. In the vertical indoor unit, the discharge port may be formed on the front surface or the side surface of the casing, and the suction port may be formed on the rear surface of the casing.
In the vertical indoor unit, air having passed through the heat exchanger is discharged through discharge ports provided on both sides of the casing.
In this regard, in the prior art (korean laid-open patent publication No. 10-2011-0045738, publication date: 2011, 05/04 th date, title of the invention: multi-discharge air conditioner), a pair of frames having a predetermined interval are provided in a main body to fix an indoor heat exchanger. And, the prior art includes: a flow path guiding member fixed to the frame so as to surround the indoor heat exchanger and guiding cool air formed in the indoor heat exchanger upward; and an upper discharge casing for discharging the cold air guided by the flow path guiding member to the front.
However, in the prior art, since no additional guide member is provided for guiding the air having passed through the indoor heat exchanger to the upper discharge casing, a part of the air flow moving toward the upper discharge opening through the indoor heat exchanger contacts the inner side surface of the upper discharge casing, and cannot flow together with the flow of the discharged air, and a separation phenomenon occurs.
Since the conventional technique generates flow separation of the discharge air flow between the indoor heat exchanger and the upper discharge port, there is a problem in that flow noise increases due to pressure loss.
In addition, in the prior art, the cold air flow passing through the indoor heat exchanger cannot be discharged to the outside of the upper discharge casing and stays in the circulation inside the upper discharge casing, so that the problem of frosting phenomenon occurs at the outside of the upper discharge casing.
In addition, in order to prevent the phenomenon of frosting on the outer side of the upper discharge casing, the conventional technology has a problem that the manufacturing cost is increased because an additional heat insulating material is provided on the inner side of the upper discharge casing.

[ door Assembly ]
The door assembly 40 includes: a front door module 45 for opening and closing the front discharge port 15 formed in the front case 22 and converting the direction of the air flow discharged through the front discharge port 15; side door modules 50 for opening and closing side discharge ports 14 provided on both sides of the case 11; and a hidden vane module 60 for converting the direction of the air flow discharged through the side discharge port 14.
The front door module 45 is provided between a rearmost position, which is a position closing a flow path of the air discharged through the front discharge port 15, and a frontmost position, which is a position forming a frontward directed air flow, and reciprocates in the front-rear direction.
In a state where the front door module 45 is projected to the forefront position, the operation mode in which the forward directed airflow is generated is set to the direct wind operation mode separately from the indirect wind operation mode.
The front door module 45 may stop at an aligned position corresponding to an intermediate position between the rearmost position and the foremost position. The aligned position is a position where the outer panel 46 of the front door module 45 disposed on the forefront side is located on substantially the same plane as the front face of the front case 22.
If the front door module is stopped at the aligned position, the air discharged to the front discharge port 15 is directed to the air flow from the front discharge port 15 in the lateral direction along the radial outside direction due to the outer shape of the front door module 45, instead of being discharged to the front. This operation mode may be defined as an indirect wind operation mode.
On the other hand, the outer panel 46 disposed on the forefront side of the door module is made of a translucent material, and light generated by a display unit (not shown) provided inside can be irradiated to the outside through the outer panel 46. Therefore, the outer panel 46 of the first embodiment of the present invention functions as a display that provides information to the user regarding the operation state of the indoor unit, the air quality state around the indoor unit, and the like.
The side door module 50 functions to open and close the side discharge ports 14 formed on both side surfaces of the case assembly 10.
That is, the side door module 50 functions to close the side discharge port 14 in a state where the side air blowing module 90 is not operated, for example, in a state where the operation of the entire indoor unit is interrupted and in a state where only the front air blowing module 82 of the indoor unit is operated.
In a state where the side air blowing module 90 is not operated, the side door module 50 closes the side outlet 14, so that it is possible to prevent dust and the like from flowing into and adhering to the inside of the case 11 through the side outlet 14, and to prevent foreign matter and the like that may cause a failure from flowing into the inside of the case 11.
The side door module 50 may include: a pair of side gates 52 that open and close the side discharge port 14 by moving in the front-rear direction; a side door driving unit 54 that generates driving force for each side door 52; and a pair of support frames 56 supporting the respective side doors 52 and the side door driving portions 54.
The side door 52 is supported so as to be movable from a foremost position where the side discharge port 14 is completely closed to a rearmost position where the side discharge port 14 is completely opened. The side door 52 extends to cover the entire upper end to the lower end of the case assembly 10 with a prescribed width to provide a sense of beauty to the user and to form an integral sense of the front case 22 and the case main body 20, and the outer surface of the side door 52 may be configured to have a material and shape that can form the same sense of texture as the case main body 20 and the front case 22.
The side door driving section 54 electrically drives the side door 52. In addition, the side door driving part 54 may include a gear motor, a pinion gear connected to an output shaft of the gear motor, and a rack gear converting a rotational force of the pinion gear into a linear reciprocating motion.
The gear motor is fixed to the support frame 56 corresponding to the fixing member, and the rack engaged with the pinion can be firmly fixed to the inner side surface of the side door 52.
On the other hand, as described above, the side door 52 is provided in a form extending from the upper end to the lower end of the case assembly 10. Therefore, the height of the side door 52 is very high compared to the width of the side door 52, and thus it is difficult to effectively drive each side door 52 with only a single driving portion.
Accordingly, two side door driving portions 54 are provided for each side door 52, and as shown in the figure, the side door driving portions 54 are preferably disposed at the upper and lower ends of the side door 52.
The support frame 56 supports the side door 52 rotatably, and may be disposed between the case main body 20 and the front case 22. The support frame 56 is formed with a side discharge port 14 extending in the vertical direction.
A plurality of side vanes 214 for guiding the direction of the discharged air may be disposed at the side discharge port 14. The plurality of side blades 214 may be integrally formed with the support frame 56. The plurality of side blades 214 of the first embodiment of the present invention are disposed obliquely forward and can guide air discharged to the outside of the case 11 in the forward direction. Therefore, in a state where the hidden vane module 60 is not operated, the air discharged through the side discharge port 14 is directed forward by the plurality of side vanes 214. Here, the forward-directed air flow may be defined as an air flow having an effective discharge angle of about 25 degrees with respect to the forward direction.
On the other hand, instead of the support frame 56, a blade that performs the same function as the side blade 214 provided to the support frame 56 may be formed in another member. For example, the side blades 214 may be integrally formed on the side surface of the side air blowing module 90 described later.
The side blades 214 may be provided on both the support frame 56 and the inner cover.
The hidden vane module 60 functions to convert the front-directed airflow discharged through the side discharge port 14 into the side-directed airflow.
As described above, the air discharged from the side discharge port 14 is directed forward by the side blades 214 of the support frame 56 or the side blades 214 of the discharge guide 190.
The hidden vane module 60 functions as a vane that converts the direction of the front-pointing airflow. The direction of the forward-directed air flow is changed by a plate-shaped hidden vane disposed adjacent to the front side of the side discharge port 14.
More specifically, when the side air blowing module 90 is operated in the direct wind mode in which the front direction air flow is established, the hidden blades of the hidden blade module 60 are in a state hidden in the storage position on the rear surface side of the front case 22 or remain in a hidden state. Therefore, the hidden vane does not affect the air flow of the air discharged through the side discharge port 14, and the discharged air keeps the front direction to the air flow.
However, if a hidden blade driving unit (not shown) is activated to switch from the direct wind mode to the indirect wind mode, the hidden blade starts to move horizontally from the storage position in the direction of being exposed to the outside. If the horizontal movement is started, the movement of the hidden blade to the final extended position is stopped after the end.
When the movement of the hidden vane to the final extended position is completed, the air discharged through the side discharge port 14 is blocked by the hidden vane, and in particular, the air passing through the front end side of the side discharge port 14 directly collides with the hidden vane, whereby the movement direction is switched.
At this time, the flow rate of the air passing through the front end portion side is the fastest among the air discharged through the side discharge port 14. Therefore, the air whose moving direction is converted by collision with the hidden blade affects the moving direction of the air discharged from the rear side. By this influence, the overall movement direction of the air through the side discharge port 14 is converted to form a side-directed air flow.
The side spouts 14 provided on both sides of the case 11 include a left side spout 14 and a right side spout 14. The left hiding vane 62 and the right hiding vane 64 may be provided one corresponding to each of the left and right spouts 14 and 14. As a modification, the left hidden blade 62 and the right hidden blade 64 may be divided into a plurality of pieces.
The hidden vane driving part (not shown) may include a gear motor, a pinion (not shown) connected to an output shaft of the gear motor, and a rack (not shown) converting a rotational force of the pinion into a linear reciprocating motion so as to be able to electrically drive the hidden vane.

The description of the first air blowing module 92 is similarly applicable to the second air blowing module 94 and the third air blowing module 96.
[ air supply fan ]
The blower fan may be modified in various embodiments within the technical idea that the blower fan is rotatably provided inside the inner cover and is capable of moving air in the direction of the discharge port 13. The blower fan of the first embodiment of the present invention is located at the center of the inner housing and rotated by receiving external power.
As the blower fan, a diagonal flow fan may be used, but this is only the first embodiment of the present invention, and other types of fans may be used as the blower fan of the present invention.
[ inner cover ]
Fig. 4 is a top cross-sectional view of the air conditioner 1 according to the first embodiment of the present invention, and fig. 5 is a top cross-sectional view showing the flow of air through the air conditioner 1 according to the first embodiment of the present invention.
As shown in fig. 3 to 6, the blower fan is rotatably provided inside an inner housing, and a blower inlet 152 into which air flows is formed in a side surface of the inner housing facing the heat exchanger 71. Further, an air supply outlet 192 is formed in a side surface of the inner cover facing the discharge port 13 of the case 11. The air supply outlets 192 of the first embodiment of the present invention are formed on both sides of the inner housing in the width direction. In addition, the inner cover may include a blower fan cover 150 and a discharge guide 190. Air flows into the inside of the inside cover through the air guide 300, and a space for installing the blower fan is formed inside the inside cover.
[ air supply Fan cover ]
The blower fan is rotatably provided inside the blower fan housing 150, and the blower fan housing 150 may be provided with a blower inlet 152 having a circular shape and a front exhaust 154 having a non-circular shape. A first air guide surface 160 is formed on the inner surface of the blower fan housing 150, and the first air guide surface 160 guides the flow of air discharged from the blower fan forward.
The blower fan housing 150 performs a function of housing the blower fan therein, and also performs a function of converting the flow direction of the air passing through the blower fan for the first time. The blower fan housing 150 is located behind the blower fan, and the ejection guide 190 is located in front of the blower fan. The blower fan cover 150 and the discharge guide 190 are coupled to each other with a blower fan interposed therebetween, and form a movement path of air.
More specifically, in the indoor unit according to the first embodiment of the present invention, a diagonal flow fan is used as the blower fan, and the rotation shaft of the diagonal flow fan extends from the front surface to the rear surface of the casing 11, and discharges the air sucked into the center radially outward.
Accordingly, the air discharged by the blower fan using the diagonal flow fan is discharged in a diagonal direction substantially perpendicular to the rotation axis in a state having a rotation speed component. As described above, the blower fan housing 150 functions to convert the flow direction of the air discharged in the diagonal direction perpendicular to the rotation axis into the forward direction.
The air supply inlet 152 of the air supply fan housing 150 has a circular shape, and the front exhaust port 154 has a quadrangular shape.
A housing base 180 having a square front outlet 154 is provided on the front side of the blower fan housing 150 so that the square front outlet 154 can be formed. The annular flare 170 is located radially outward of the circular air supply inlet 152. Since the inlet protrusion of the blower fan is located outside the flare 170, it is possible to prevent a part of the air moving forward by the blower fan from moving back again to the return air of the air flowing to the inlet of the blower fan through the space between the blower fan and the blower fan housing 150.
The bell mouth 170 is provided in a ring shape on the inner side of the blower fan housing 150 facing the blower inlet 152. The flare 170 has a longitudinal section of a concave shape surrounding an end of an inlet boss provided to the blower fan and extends in a circumferential direction.
The flare 170 may be formed in a shape surrounding the outer peripheral surface of the blower inlet 152 formed in the center of the blower fan housing 150. The flare 170 may be formed to protrude rearward and form a groove portion in a shape recessed forward.
In addition, at least a portion of the flare 170 may be inserted radially inward of the blower fan. Such a flare 170 can help to improve the suction and discharge performance of the side air blowing module 92 by guiding the suction flow at the inlet of the air blowing fan. In addition, since the rear of the first air guide surface 160 connected to the bell mouth 170 is formed as a convex curved surface, an increase in frictional resistance of air moving forward through the bell mouth 170 can be reduced, and the blowing of air can be more smoothly formed.
The first air guide surface 160 has a dome shape formed to protrude rearward in a curved shape with a prescribed curvature to prevent the formation of a vortex or a vortex in the course of switching the flow direction of the air discharged from the blower fan.
The flow of the air in the flow direction is switched by the inner surface of the fan housing, and the flow direction is switched to the side direction by the discharge guide 190 for the second time while the flow direction is switched to the first time in a state having a predetermined rotational speed component.
Accordingly, the inner side surface of the first air guide surface 160 may be shaped to expand the cross-sectional area of the flow path so that the air rotationally discharged from the blower fan can restore pressure while traveling in the flow direction.
The side discharge openings 14 formed in both sides of the case 11 are formed in front of the left and right edges of the blower fan housing 150, respectively.
On the other hand, the blower fan is accommodated in the blower fan housing 150 in a state where the rotation shaft has directivity extending in a direction from the front surface toward the rear surface of the case 11. The blower fan uses a diagonal flow fan that sucks air flowing in from the blower inlet 152 formed in the rear blower fan housing 150 along the center side and discharges the air in a diagonal direction along the radial outside.
[ spitting guide ]
The discharge guide 190 may be modified in various embodiments within the technical idea of guiding the air having passed through the blower fan to the side discharge port 14.
The discharge guide 190 is coupled to the front discharge port 154 of the blower fan housing 150, and a blower outlet 192 for guiding the air having passed through the blower fan to the discharge port 13 may be formed on both sides in the width direction of the discharge guide 190. A second air guide surface 200 is formed on the back surface of the discharge guide 190, and the second air guide surface 200 guides the flow of air guided by the first air guide surface 160 to the side of the discharge port 3. A flow path of air is formed between the first air guide surface 160 and the second air guide surface 200.
The discharge guide 190 is coupled to the front of the blower fan housing 150, and serves to perform a second switching of the flow of air in the flow direction that is switched by the blower fan housing 150 for the first time.
The ejection guide 190 includes a flat plate-shaped base plate 194. The base plate 194 has a flat plate shape with a substantially constant thickness in the front-rear direction.
On the other hand, a motor mounting portion 196 is formed on the rear center side of the base plate 194, and the motor mounting portion 196 supports the blower fan and also functions as a support side blower motor 220. The rear shape of the motor mounting portion 196 corresponds to the inner shape of the blower fan so as to be able to support the blower fan. The motor mounting portion 196 protruding in a rearward protruding shape is inserted into the interior of the blower fan forming the recessed groove portion.
The front shape of the motor mounting portion 196 is a rearward recessed shape, and a side blower motor 220 is mounted inside the motor mounting portion 196 forming a recessed groove.
Three fastening bosses 197 are provided inside the front of the motor mounting portion 196. The motor bracket 222 for fixing the side Fang Songfeng motor 220 is fixed to the fastening boss 197.
The central portion of the discharge guide 190 is formed substantially in a plane, and both side wing portions of the discharge guide 190 are bent forward. Therefore, the air discharged from the blower fan is discharged in a direction inclined forward.
The second air guide surfaces 200 are provided on both sides in the width direction of the base plate 194, and the second air guide surfaces 200 are formed integrally with the base plate 194 and extend in a forwardly bent shape.
By the bent shape of the second air guiding surface 200, the flow path sectional area of the air may be gradually expanded with the flow direction of the air.
More specifically, the second air guide surface 200 forms a predetermined inclination angle with respect to the back surface of the base plate 194 and extends in a direction away from the first air guide surface 160.
As described above, the flow direction of the air discharged from the blower fan is first converted by the first air guide surface 160 of the blower fan housing 150 and is guided to the rear surface side of the discharge guide 190.
[ air guide ]
Fig. 7 is a front perspective view of an air guide 300 according to a first embodiment of the present invention, fig. 8 is a perspective view showing a first air guide 310 according to the first embodiment of the present invention, and fig. 9 is a rear perspective view of the air guide 300 according to the first embodiment of the present invention.
As shown in fig. 7 to 9, the air guide 300 into which the air having passed through the heat exchanger 71 flows can be modified in various embodiments within the technical idea of converting the flow path of the air having passed through the heat exchanger 71 into a circular flow path.
Since the outlet of the heat exchanger 71 and the inlet of the air blowing module portion 80 are connected by the air guide 300, the air passing through the heat exchanger 71 can stably move toward the air blowing module portion 80. Further, since the air having passed through the heat exchanger 71 moves along the curved air guide 300, it is possible to reduce the flow separation of the air moving from the heat exchanger 71 to the inlet of the air blowing module 80. Further, since the air guide is provided between the heat conduction surface of the heat exchanger 71 and the air supply inlet 152 of the air supply module unit 80, the pressure loss of the air supply flow can be prevented, and the flow noise can be reduced by reducing the vortex flow caused by the flow separation of the air supply flow inside the case.
For this, the air guide 300 may be provided with a quadrangular-shaped guide inflow portion 340 and a circular-shaped guide discharge portion 350. The width of the guide inflow portion 340 is slightly larger than the width of the heat exchanger 71 so as to cover the entire heat exchanger 71, and the air passing through the heat exchanger 71 can smoothly flow into the air blowing module portion 80.
The air guide 300 is provided between the heat exchanger 71 and the air-blowing module portion 80, and forms a duct that guides the air having passed through the heat exchanger 71 to the air-blowing inlet 152 of the air-blowing module portion 80. The air guide 300 is spaced apart from the case 11, and a heat insulating space 700 is formed between the air guide 300 and the case 11. Therefore, an additional heat insulating material for preventing frosting is not required between the air guide 300 and the case 11, so that the production cost can be reduced.
The air guide 300 of the first embodiment of the present invention may include: a guide inflow portion 340 forming a passage through which the air passing through the heat exchanger 71 flows; a guide discharge unit 350 for guiding the air flowing in through the guide inflow unit 340 to the air supply inlet 152; and a guide body part 360 connecting the guide inflow part 340 and the guide discharge part 350.
The width direction length of the guide inflow portion 340 is equal to or longer than the width direction length of the heat exchanger 71. In addition, the guide inflow portion 340 may have a quadrangular shape or a quadrangular shape with one side opened. The heat exchanger 71 of the first embodiment of the present invention has a rectangular parallelepiped shape extending in the up-down direction, and the guide inflow portion 340 and the heat exchanger 71 may be provided in a facing shape. The guide inflow portion 340 may be provided in plural numbers and may be provided continuously in the vertical direction.
The guide inflow portion 340 of the first embodiment of the present invention may include a first guide inflow portion 311 and a second guide inflow portion 321. The second guide inflow portion 321 is located at the lower side of the first guide inflow portion 311.
The air flowing in from the first guide inflow portion 311 moves toward the front air blowing module 82 through the first guide discharge portion 312, and moves toward the first air blowing module 92 through the second guide discharge portion 314.

Accordingly, the air guide 300 blocks air existing in the first air guide 310 and the second air guide 320 from mixing.
Air flow of air conditioner
Air to be air-conditioned is sucked through the suction port 12 of the casing 11. Foreign matter in the air sucked from the suction port 12 is removed when passing through the filter assembly 800. The air that has exchanged heat with the refrigerant when passing through the heat exchanger 71 is supplied to the front air-sending module 82 and the side air-sending module 90 via the air guide 300. And then discharged to the outside of the case 11.
Next, the flow of air through the air guide 300 will be described in more detail. Since the air having passed through the heat exchanger 71 is guided to the air blowing module 80 along the air guide 300, the flow separation phenomenon of the air flow moving from the heat exchanger 71 to the air blowing module 80 can be reduced, and the flow noise can be reduced.
If the air guide 300 is not provided, air moving from the heat exchanger 71 to the air blowing module 80 contacts the inside of the case 11, and flow separation occurs due to friction force generated.
A part of the airflow moving from the heat exchanger 71 to the blower module unit 80 rubs against the side surface of the case 11, and cannot follow the suction flow, thereby causing separation. The flow separation as described above causes pressure loss and increases in flow noise. In addition, when the cold air flow passing through the heat exchanger 71 is circulated inside the casing 11, there is a possibility that frost may be formed outside the casing 11 under high-temperature and high-humidity environmental conditions outside the casing 11.
Accordingly, since the air guide 300 is provided to form a passage through which the air having passed through the heat exchanger 71 can move toward the air blowing module 80, it is possible to reduce the flow noise by reducing the separation phenomenon of the air flow moving from the heat exchanger 71 toward the air blowing module 80.
Since the curved surface is provided on the inner side of the air guide 300 to reduce the frictional resistance of the air and thus reduce the flow separation phenomenon, the phenomenon that the flow noise increases due to the vortex flow generated by the flow separation can be alleviated.
In the present invention, the cooling air flow having passed through the heat exchanger 71 moves toward the air blowing module 80 via the air guide 300, and thus, the case 11 is not frosted. Since the heat insulating layer is formed by the heat insulating space portion 700 formed between the air guide 300 and the case 11, it is possible to prevent the case 11 from frosting.
By the air guide 300 provided between the heat exchanger 71 and the air blowing module portion 80, loss of air flow can be minimized, and as the heat insulation space portion 700, which is a hollow heat insulation region, is formed in the space between the outer side surface of the air guide 300 and the case 11, it is possible to prevent the occurrence of the phenomenon of frosting on the outer side of the case 11.
Further, by using the air guide 300 and the heat insulating space 700, it is not necessary to use a heat insulating material for preventing frost formation in the case 11, and therefore, the material cost and the manufacturing cost can be reduced.
As described above, the present invention reduces flow noise by removing flow separation occurring at the inlet of the air blowing module unit 80, and further can prevent occurrence of frost formation on the outer surface of the casing 11 due to flow separation. In addition, in order to eliminate the flow separation phenomenon occurring inside the case 11 when the cooling air flow moves toward the air supply module portion 80 through the heat exchanger 71, the air guide 300 is additionally provided, so that the flow noise can be reduced and the heat insulation effect between the case 11 and the guide portion can be obtained.

As shown in fig. 10 to 13, the outer side edge of the guide body part 460 of the air guide 400 of the second embodiment of the present invention may be formed in a quadrangular shape. The air guide 400 of the second embodiment of the present invention is different from the air guide 400 of the first embodiment of the present invention only in the shape of the guide body part 460, and the remaining constitution is almost similar or identical, so that a detailed description thereof is omitted.
Since the outlet of the heat exchanger 71 and the inlet of the air blowing module portion 80 are connected by the air guide 400, the air passing through the heat exchanger 71 can stably move toward the air blowing module portion 80. The air guide 400 may be provided with a guide inflow portion 440 of a quadrangular shape and a guide discharge portion 450 of a circular shape.
The air guide 400 of the second embodiment of the present invention may include: a guide inflow portion 440 forming a passage through which air having passed through the heat exchanger 71 flows; a guide discharge portion 450 for guiding the air flowing in through the guide inflow portion 440 to the air supply inlet 152; and a guide body 460 connecting the guide inflow portion 440 and the guide discharge portion 450.

The first and second guide inflow parts 411 and 421 form rectangular inlets, and extend in the up-down direction.
The guide discharging part 450 may form a hole of a circular shape. In addition, the guide discharging part 450 may be provided in plural numbers, and may be provided in the up-down direction along the guide main body part 460. The guide discharge portion 450 is in contact with the rear side of the blower fan housing 150 so that the air passing through the guide discharge portion 450 can be transferred to the inside of the blower fan housing 150 without leakage.
The guide and discharge portion 450 of the second embodiment of the present invention includes a first guide and discharge portion 412, a second guide and discharge portion 422, a third guide and discharge portion 423, and a fourth guide and discharge portion 424.

The second guide/discharge portion 422 connected to the first blower module 92 is provided with a concave groove-shaped curved surface mounting portion 427. Since the curved surface mounting portion 427 is in contact with the first air blowing module 92 having a shape protruding rearward, the second guide discharging portion 422 blocks the leakage of the cool air to the outside of the air guide 400 by surface contact with the first air blowing module 92.
Since the same configuration as the curved surface mounting portion 427 is also provided in the first guide discharge portion 412, the third guide discharge portion 423, and the fourth guide discharge portion 424, a detailed description thereof will be omitted.

The first guide separating body 414 connects the first guide inflow portion 411 and the first guide discharge portion 412, and guides the movement of air from the first guide inflow portion 411 to the first guide discharge portion 412.
The guide body 460 is connected to the second guide inflow portion 421, the second guide discharge portion 422, the third guide discharge portion 423, and the fourth guide discharge portion 424. The air flowing in through the second guide inflow portion 421 is thus guided to the second guide discharge portion 422, the third guide discharge portion 423, and the fourth guide discharge portion 424.
The second guide inflow portion 421 forms a quadrangular passage, and the second guide discharge portion 422, the third guide discharge portion 423, and the fourth guide discharge portion 424 form a circular passage. Therefore, since the inner body 466 has a curved shape, it is possible to prevent or reduce the occurrence of a vortex, turbulence, or the like while the air moving from the guide inflow portion 440 to the guide discharge portion 450 is converged to the circular discharge portion.
The air guide 400 including the guide inflow portion 440, the guide discharge portion 450, and the guide main body portion 460 may be separated into the first air guide 410 and the second air guide 420.

The guide body part 460 includes a support body 462, a connection edge 464, an inner body 466, and a concave-convex protrusion 468, and guides the air flowing in through the second guide inflow part 421 to the second guide discharge part 422, the third guide discharge part 423, and the fourth guide discharge part 424.
The air blocking portion 430 may be modified in various embodiments within the technical idea of protruding from the second air guide 420 toward the heat exchanger 71 and dividing the inside of the second air guide 420 into a plurality of spaces. The air blocking portion 430 of the second embodiment of the present invention protrudes toward the rear side of the second air guide 420, and a partition wall is formed between the second and third guide discharge portions 422 and 423. Therefore, the air guide 400 blocks the air discharged to the second and third guide discharge portions 422 and 423 from mixing.
