Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. It should be noted that, in adding reference numerals to the constituent elements of the drawings, the same constituent elements are denoted by the same reference symbols as possible even if they are shown in different drawings. In the following description of the embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the difference that the embodiments of the present invention are not conclusive.

1 is a bottom perspective view showing a state in which a front panel is separated from an indoor unit of a ceiling-type air conditioner according to an embodiment of the present invention.

1, the ceiling type air conditioner according to the present invention includes an outdoor unit (not shown) installed in an outdoor space, an indoor unit 1 installed in an indoor space, and an outdoor unit (not shown) And a refrigerant pipe (not shown) to which the refrigerant is transferred.

The indoor unit 1 may be coupled to the lower end of the installation member F and the upper end of the installation member F may be coupled to the ceiling so that the indoor unit 1 may be suspended from the ceiling.

The indoor unit 1 includes a main body 10 forming an outer appearance of the main body 10, a front panel 20 coupled to the main body 10 to form a lower outer appearance of the main body 10, Of 30). The overall appearance of the indoor unit 1 can be formed by the main body 10, the front panel 20, and the base 30. [

A heat exchanger (12 of FIG. 2) may be disposed inside the main body 10. Therefore, the air sucked into the indoor unit (1) can be discharged to the outside after heat exchange with the heat exchanger (12).

The main body 10 may be opened to communicate with the suction port 21 formed on the front surface of the front panel 20. The front panel 20 may be coupled to the main body 10 to cover the open portion of the main body 10. For this, the front panel 20 may have a plate shape corresponding to the lower shape of the main body 10 so as to cover the opening of the main body 10. For example, the front panel 20 may have the shape of a rectangular plate.

The front panel 20 is provided with a suction port 21 for sucking indoor air and a discharge port 22 for discharging indoor air after the indoor air sucked into the indoor unit 1 is heat-exchanged . The suction port 21 may be disposed at a central portion of the front panel 20. The discharge ports 22 may be symmetrically formed on the outer sides of the suction port 21, respectively. The suction port 21 may be formed in a grill structure. The discharge port 22 may have a rectangular structure having a predetermined width and length. However, the shapes of the suction port 21 and the discharge port 22 are not limited thereto.

A filter (not shown) for removing foreign substances contained in the air sucked into the main body 10 through the suction port 21 may be provided inside the front panel 20.

2 is an exploded perspective view showing the internal structure of the indoor unit of the ceiling-type air conditioner according to the embodiment.

Referring to FIG. 2, the main body 10 may be formed by combining a plurality of plates. The main body 10 can shield the inside of the indoor unit 1 by forming front, rear, left and right outer surfaces of the indoor unit 1. [ The lower end of the main body 10 is coupled to the front panel 20 and the upper end of the main body 10 can be engaged with the lower surface of the base 30. Therefore, when the base 30 and the front panel 20 are coupled to the upper and lower ends of the main body 10, the heat exchanger 12 and the fan 14 can be accommodated in the indoor unit 1 A space can be formed.

The main body 10 may further include a drain plate 11 capable of collecting condensed water generated through heat exchange. The drain plate 11 may be disposed above the front panel 20. In detail, the drain plate 11 is capable of collecting condensed water generated on the outer surface of the heat exchanger 12 when the refrigerant passing through the heat exchanger 12 and the room air exchange heat. For this purpose, the drain plate 11 may be formed with a water collecting space (not shown) in which the upper surface thereof is recessed to collect condensed water.

The lower end of the indoor heat exchanger 12 may be received and seated in the water collecting space. Therefore, the condensed water formed on the outer surface of the indoor heat exchanger 12 flows downward and can be collected in the water collecting space.

A drain pipe (not shown) for discharging the condensed water collected in the collecting space to the outside may be connected to the drain plate 11.

A through hole 111 may be formed at the center of the drain plate 11 to allow the air flowing through the inlet 21 to flow upward. Therefore, the air purified by the filter can flow upward through the drain plate 11. [

The heat exchanger 12 may be disposed on the upper surface of the drain plate 11. In order to heat exchange the air purified by the filter, a refrigerant that exchanges heat with room air may flow into the heat exchanger (12). The heat exchanger 12 may be formed to correspond to a side surface shape of the main body 10. For example, when the side surface of the body 10 is formed in a square shape, the heat exchanger 12 may have a square structure corresponding thereto.

In order to improve the heat exchange efficiency between the air and the refrigerant, the heat exchanger 12 may have a shape in which an elongated tube is bent many times so as to enlarge the area. Therefore, indoor air that has flowed upward through the through-hole 111 can exchange heat with the heat exchanger 12.

For example, when the ceiling-type air conditioner is in the cooling operation mode, the temperature of the air passing through the heat exchanger 12 is lowered and the air passing through the heat exchanger 12 during the heating operation of the ceiling- Can be increased. At this time, the condensed water generated on the outer surface of the heat exchanger (12) during the heat exchange can be collected in the collecting space.

The main body 10 may further include an air guide 13 for preventing internal air from leaking to the outside of the main body 10. The air guide 13 may be disposed between the main body 10 and the heat exchanger 12. In addition, the cross-sectional size of the air guide 13 may be larger than the heat exchanger 12 and smaller than the front panel 20. Therefore, the heat-exchanged air with the refrigerant may not leak to the outside of the main body 10 while flowing outwardly from the inside of the heat exchanger 12.

The fan 14 may be disposed at the center of the main body 10. The fan (14) can cooperate with the fan motor (141) generating the rotational power when the power is applied, and can force the air flow. Accordingly, when the fan motor 141 operates, an upward suction force can be generated in the center portion, and a wind force can be generated inward from the inside in the outer peripheral surface direction. Accordingly, when the fan 14 receives the rotational power from the fan motor 141 and rotates at a high speed, the suction force generated at the lower side is transmitted to the through-hole 111 and the suction port 21, Can be inhaled. The indoor air sucked into the central portion of the fan (14) is blown in the direction of the outer circumferential surface and passes through the heat exchanger (12), so that heat exchange by the refrigerant can be performed.

The main body 10 may include an orifice 15 provided in the through-hole 111. The orifice 15 may guide the air flowing upward from the lower side of the drain plate 11 into the central portion of the fan 14. For this purpose, the orifice 15 may have a cylindrical shape increasing in diameter toward the bottom. In addition, the lower end of the orifice 15 may be coupled so as to lie on the same plane as the bottom surface of the drain plate 11.

An orifice hole 151 may be formed in the orifice 15 so as to be vertically perforated. The fan 14 may be disposed inside the orifice hole 151.

Accordingly, when the fan 14 rotates to generate a suction force downward, the air below the drain plate 11 flows upward along the orifice hole 151, And may be introduced into the central portion.

The main body 10 includes a plasma filter 16 disposed on the left side of the lower surface of the orifice 15 and a filter bracket (not shown) provided on the plasma filter 16 to restrain the plasma filter 16. As shown in FIG. The plasma filter 16 generates plasma to attract and adsorb foreign matter contained in the air. In addition, the filter bracket may be coupled to the lower surface of the orifice 15.

The main body 10 may further include a dust filter (not shown) provided between the filter bracket and the plasma filter 16. The dust filter may be removably mounted on the filter bracket for filtering the fine foreign matter that has not been removed despite the secondary filtering of the air filter and the plasma filter 16.

In this embodiment, at least one of the air filter, the plasma filter, and the dust collecting filter provided in the ceiling-mounted air conditioner may be omitted. In addition, a separate filter may be additionally mounted in addition to the filters.

The main body 10 may further include a control box 17 for controlling the operation of the indoor unit 1. A space of a predetermined size may be formed in the control box 17 to incorporate a printed circuit board (not shown).

The main body 10 may further include a panel elevating means 18 provided on a lower surface of the orifice 15. [ The panel elevating means 18 is for selectively lifting and lowering the front panel 20 and may be installed between the orifice 15 and the front panel 20.

The panel lifting unit 18 includes a plurality of lifting and lowering kits 181 that generate large rotational power to force the upper panel 20 upward and downward and a lower end coupled to the lifting unit 21, And a wire 182 for transmitting the rotational power generated by the motor 181 to the inlet 21.

Therefore, if the lifting and lowering kit 181 extends the length of the wire 182, the suction port 21 can be kept open.

On the contrary, when the lifting kit 181 pulls the wire 182, the suction port 21 flows upward to shield the suction port 21. [

Hereinafter, the specific structure of the front panel 20 will be described.

FIG. 3 is a top perspective view of a front panel according to an embodiment, and FIG. 4 is an exploded perspective view of a front panel according to an embodiment.

Referring to FIG. 3, the front panel 20 may include a vane 23 for controlling a flow direction of air discharged into a room. The vane 23 may be configured to be rotatable at a predetermined angle. The vane 23 may be inclined outward from the front surface of the front panel 20. Therefore, it is possible to provide a wind having a uniform wind velocity in all the rooms. However, the direction of rotation of the vane 23 is not limited thereto. Also, the arrangement, construction, and operation of the vane 23 are not limited thereto.

The front panel 20 may include a motor accommodation space 24 in which a vane motor 231 described later can be disposed. The motor housing space 24 may be provided at the left and right corners of the front panel 20. The motor accommodating space 24 may be partitioned from the upper space of the front panel 20 by a partition rib 232.

The front panel 20 may further include a vane motor 231 for adjusting the angle of rotation of the vane 23. The vane motor 231 may be disposed in the motor accommodation space 24 as described above. The vane motor 231 may be provided in an amount corresponding to the vane 23. In addition, the plurality of vane motors 231 may be selectively operated.

The front panel 20 may further include an inspection port 25 through which a tool such as a driver can be inserted when the front panel 20 is detached from the main body 10. [ The inspection hole 25 may be formed through any part of the motor accommodation space 24. The inspection hole 25 may be formed as a triangle, for example.

The front panel 20 may further include a panel flange 251 provided on one side of the inner wall surface of the inspection hole 25. [ The panel flange 251 may protrude into the inspection hole 25.

The panel flange 251 may include a panel coupling hole 252 for fixing the front panel 20 to the main body 10 to be fixed thereto. Accordingly, the front panel 20 may not be detached from the main body 10 by fastening the panel coupling hole 252 and the later-described coupling hole (191 in FIG. 2) by the fastening member.

The front panel 20 may further include a motor cover 241 for shielding the motor accommodation space 24. At this time, the motor cover 241 may be formed in a shape that does not cover the inspection hole 25. A motor escape groove 242 may be formed on the upper surface of the motor cover 241. Therefore, the motor escape groove 242 may be formed larger than the upper surface of the vane motor 231 to prevent the vane motor 231 from interfering with the motor cover 241. The motor escape groove 242 may be recessed upward from the lower surface of the motor cover 241.

The front panel 20 may further include a plurality of protrusion penetrations 253 for supporting a load of an inspection port cover 254 to be described later.

The front panel 20 may further include an inspection port cover 254 for shielding the inspection port 25. The check port cover 254 may be coupled to an edge of the front panel 20 to form a part of an outer appearance of the indoor unit 1. [ Also, the check cover 254 may be selectively detached from the front panel 20 by sliding at the corner.

The check port cover 254 may include a plurality of locking protrusions 255 for supporting a load on the front panel 20. The locking protrusion 255 may be formed at a position corresponding to the protrusion penetration portion 253. The stopper protrusion 255 is coupled to the protrusion penetration portion 253 so that the inspection port cover 254 can be coupled to the front panel 20.

Referring to FIG. 1 again, the main body 10 may include a panel bracket 19 protruding outwardly from the lower end of the main body 10. The panel bracket 19 may have a fastening hole 191 for fastening a fastening member such as a screw. The fastening hole 191 can be fastened by the panel flange 251 and the fastening member. Therefore, when the panel bracket 19 and the panel flange 251 are coupled by the fastening member, the load of the front panel 20 can be supported by the main body 10.

The main body 10 may include a plurality of the hanger assemblies 40 for engaging with the lower end of the installation member F. [ The plurality of hanger assemblies 40 may be disposed on each of the corner surfaces to stably support the body 10 from the ceiling C, The ceiling C may be provided with an installation member F corresponding to the number of the hanger assemblies 2. A plurality of mounting members F provided on the ceiling C may be positioned on the front and rear sides and the left and right sides of the main body 10 and a plurality of the hanger assemblies 40 may be disposed on the main body 10 And can be coupled to the lower end of the mounting member F, respectively.

When the lower end of the mounting member F is coupled to the hanger assembly 40, the remaining components except for the front panel 20 may be suspended from the ceiling.

Hereinafter, the specific structure of the hanger assembly 40 will be described.

FIG. 5 is a view of a hanger assembly disposed in a body according to an embodiment, FIG. 6 is an exploded perspective view of a hanger assembly according to an embodiment, and FIG. 7 is a cross-sectional view of a hanger assembly disposed in a body according to an embodiment.

Referring to FIG. 5, the hanger assembly 40 may be disposed at the lower end of the body 10. Further, the hanger assembly 40 may be disposed above the inspection port 25 so as to be operable at the inspection port 25.

The hanger assembly 40 may include a main body mount 41 fastened to the main body 10 and adapted to adjust the distance between the main body 10 and the ceiling.

The main body mounter 41 may further include a first mount portion 411 coupled to the main body 10 by a mount coupling member 412. A mount hole 411a into which the mount bolt 412a can be inserted may be formed in any one portion of the first mount portion 411. [ When the mount bolt 412a is inserted into the mount hole 411a, the mount bolt 412a on the rear surface of the main body 10 can be fastened by the mount nut 412b.

Therefore, the main body mounter 41 can be supported by the main body 10 by the mount fastening member 412.

The main body mounter 41 may further include a second mount portion 414 formed by bending the first mount portion 411 at least once. The second mounting portion 414 may be formed with a first insertion hole 414a into which the fastening member 45 can be inserted.

The hanger assembly 40 may further include a support 42 coupled to the mounting member F. [ The support 42 is connected to the main body mounter 41 and can slide upward and downward.

The support 42 may further include a first support 421 coupled to a lower end of the installation member F. [ The first support body 421 may be provided with an installation hole 421a into which the installation member F can be inserted. Therefore, the mounting member F can be inserted into the mounting hole 421a and fastened by the mounting nut 421b.

As another example, the lower end of the installation member F inserted into the installation hole 421a may be formed wider than the upper end of the installation member F. [ Therefore, the mounting member F can be supported by the first support body 421. [

The supporting member 42 may further include a connecting portion 422 for connecting the first supporting member 421 and a second supporting member 423 to be described later. The connection member 422 has an effect that the attachment member F installed on the first support member 421 does not interfere with the second support member 423. [

The connecting portion 422 may include a bent portion 422b for avoiding the mount fastening member 412 on the upper side or the lower side of the first supporting member 421. [ The bending portion 422a is formed at least once from the first support body 421 so that a clearance space 422e for preventing interference with the mount coupling member 412 can be formed. For example, when the support 42 slides downward, the mount coupling member 412 is not interfered with due to the avoidance space 422e.

In addition, the connection portion 422 may further include a contact portion 422b that is in contact with the main body. The contact portion 442b may contact a part of the main body 10 while being bent at least once from the first support body 421. [ Accordingly, when the support 42 slides upward and downward, the contact portion 422b can be slid in the vertical direction while contacting the main body 10. Further, the sliding contact of the contact portion 422b is advantageous in that the main body can be lifted and lowered more securely while minimizing the swinging of the main body. In addition, since the contact portion 422b is formed by bending, a part of the load of the main body 10 can be dispersed. Therefore, the durability of the support 42 is improved.

The connection portion 422 includes an upper connection portion 422c for connecting the contact portion 442b and the bent portion 422a and a lower connection portion 422d for connecting the bending portion 422a and a second support member 423, ).

The support 42 may further include a second support 423 to which the fastening member 45 described later may be inserted, facing the second mount 414. The coupling member 45 is inserted and fixed between the second support 423 and the second mount 414 so that the ceiling C and the main body 10 are fixed with a certain distance maintained .

Meanwhile, the second support body 423 may be bent at least once from the connection portion 422. A second insertion hole 423a through which the fastening member 45 can be inserted may be formed at a portion of the second support body 423. Therefore, the gap between the second support body 423 and the second mount 414 can be varied depending on the fastening state of the fastening member.

The hanger assembly 40 may further include a pair of guide rails 44 capable of guiding the support 42 to slide in a vertical direction with respect to the ceiling C. The pair of guide rails 44 may be in contact with the left and right sides of the connection portion 422, respectively. Further, the pair of guide rails 44 may be formed to protrude toward the main body. Therefore, the support 42 can be slid in the direction perpendicular to the ceiling C by the pair of guide rails 44. [

The hanger assembly 40 may further include a fastening member 45 for adjusting the height of the support 42. The fastening member 45 may be inserted into the first and second insertion holes 414a and 423a. The fastening member 45 may include the bolts 45a and the nuts 45b fastened to the bolts 45a. When the bolt 45a is rotated, the nut 45b can be fixed without being rotated. For example, the nut 45b may be fixed to the second support body 423 without being rotated. Accordingly, when the bolt 45a and the nut 45b are tightened, the support 42 can be slid upward. That is, the gap between the main body mounter 41 and the support body 42 can be reduced. When the distance between the mounter 41 and the support 42 is shortened, the distance between the main body 10 and the ceiling C can be reduced.

In contrast, when the bolt 45a and the nut 45b are loosened, the interval between the body mounter 41 and the support body 42 may be distant. At this time, the distance between the main body 10 and the ceiling C may be distant.

In another embodiment, a thread corresponding to the bolt 45a may be formed in the second fastening hole 423a of the second support body 423. Accordingly, as the bolt 45a is rotated, the support 42 can be slid upward and downward.

8 is a view showing a state in which the inspection port cover according to the embodiment is separated from the front panel.

Referring to FIG. 8, the check cover 254 can be detached from the front panel 20. At this time, the inside of the indoor unit (1) can communicate with the indoor space through the check port (25). At this time, the hanger assembly 40 may be positioned above the inspection port 25. [ Therefore, the operator can check the fastening state of the mounting member (F) and the hanger assembly (40) without removing the entire front panel (20). The operator can adjust the height between the indoor unit 1 and the ceiling by operating the fastening member 45 of the hanger assembly 40 using a tool such as a screwdriver.

Hereinafter, a process of reducing the clearance by operating the hanger assembly when a gap is generated between the indoor unit and the ceiling in the ceiling-type air conditioner installation process will be described.

FIG. 9 is a cross-sectional view of an indoor unit in which a clearance is generated between an indoor unit and a ceiling according to an embodiment of the present invention. FIG. 10 is a cross- And FIG. 11 is a cross-sectional view of the indoor unit in which the operation of reducing the clearance according to the embodiment is completed.

9, a clearance D2 may be generated between the indoor unit 1 and the ceiling C during installation or maintenance of the indoor unit 1 of the ceiling-type air conditioner of the operator. Due to the clearance D2, the indoor unit 1 and the ceiling C may not be horizontal, that is, the indoor unit 1 may be inclined toward either side.

At this time, the operator can open the inspection port cover 254 at the point where the clearance D2 has occurred. At this time, the distance between the main body mount 41 of the hanger assembly 40 and the support 42 may be the first height H.

Referring to FIG. 10, an operator can operate the fastening member 45 of the hanger assembly 40 using a tool T such as a screwdriver. By rotating the fastening member 45 counterclockwise, the operator can get close to the support 42 and the body mounter 41. The operator adjusts the distance between the support body 42 and the body mounter 41 to a second height L smaller than the first height H so that the body 10 on the side of the hanger assembly 40 and the ceiling C) can be reduced. By reducing the clearance D2, the main body 10 and the ceiling C can be leveled.

Referring to FIG. 11, when the operation of reducing the clearance D2 between the indoor unit 1 and the ceiling C is completed, the operator can close the inspection cover 254.

In the present specification, the height of the hanger assembly 40 at the point where the clearance has occurred has been described so as to align the ceiling with the indoor unit 1. However, the height of the opposite side of the hanger assembly 40 , It is also possible to align the ceiling with the indoor unit 1.

Conventionally, when there is a clearance between the indoor unit and the ceiling of the ceiling-type air conditioner, the operator has to hold his / her body in the inspection hole and work with the other hand. However, in the case of the present invention, since the body mounter is slidably guided to the support body so as to be adjustable in height, and the fastening member fixes the body mounter to the support body so as to be adjustable in height, Can be easily adjusted.

In addition, since the main body is slidably guided to the contact portion of the support body, there is an advantage that the main body can be raised and lowered more securely while minimizing the swinging of the main body.

In addition, the ceiling-type air conditioner according to the present invention does not require the operator to hold the main body by hand, and the size of the inspection port can be formed to be large enough to insert a tool such as a driver, There is an advantage not to be required.

In addition, since the operator can hold the ladder with one hand when adjusting the height of the indoor unit of the ceiling-type air conditioner, safety is improved when the height of the indoor unit is adjusted.
