Description
Technical Field
The present invention relates to an indoor unit (Indoor unit) of an air Conditioner (Conditioner), and more particularly, to an indoor unit of an air Conditioner capable of easily cleaning the inside of the indoor unit without removing large-sized components, even if not an expert.
Background
In general, an air conditioner is a device for cooling or heating a room by using a refrigeration cycle of a refrigerant including a compressor, a four-way valve, an outdoor heat exchanger (condenser or evaporator), an expansion mechanism, and an indoor heat exchanger (evaporator or condenser) in order to create a relatively comfortable indoor environment for a user, and is generally divided into a separate type and an integrated type.
The separate type and the integrated type are functionally identical, but the separate type is an air conditioner in which a cooling/heat radiating device, an indoor fan, and an indoor fan motor are provided in an indoor unit, a heat radiating/cooling device, a compression device, an outdoor fan, and an outdoor fan motor are provided in an outdoor unit, and the indoor unit and the outdoor unit separated from each other are connected by a refrigerant pipe, and the integrated type is an integrated cooling/heat radiating function.
Typically, the separate indoor units are provided to stand up in the room or hang on a wall or be embedded in the ceiling, while the unit is provided to be perforated in the wall of the house or hang the unit in a window or be provided outdoors and be connected to the room by pipes.
In order to clean the interior of an indoor unit (in particular, a cleaning blower) of an air conditioner according to the related art (patent document 1), it is necessary that a user first separate the front panel 202 from the casing 201 and remove a heat exchanger, an orifice, and the like located inside the casing, and then clean the blower when the blower 210 is exposed.
Therefore, in the case of patent document 1, in order to clean the blower, it is necessary to separate the front panel, the heat exchanger, and the orifice, and particularly, since the heat exchanger is connected by the refrigerant piping, there is a risk that the refrigerant flows out during the separation process, and there is a great difficulty in separating the respective members, and there is a problem that cleaning itself is difficult.
In the case of patent document 2, the front panel 4, the heat exchanger, and the orifice are also required to be separated in order to clean the blower, and therefore, there is a problem in that cleaning itself is difficult.

Hereinafter, a structure for easily cleaning the indoor unit will be described in detail.
Fig. 4 is a sectional view taken along line 17-17' of fig. 1, and fig. 5 is a view of the display panel 30 shown in fig. 1 viewed from the rear.
Referring to fig. 4 and 5, an embodiment of the present invention includes an air gap 70 formed between the display panel 30 and the cabinet 10.
The display panel 30 includes a rear frame 34 and a front frame 32, and the display unit 35 is accommodated between the front frame 32 and the rear frame 34. The front surface of the display unit 35 is exposed forward by the front frame 32, and the rear surface of the display unit 35 is exposed rearward by the rear frame 34. The display unit 35 may have a smaller area than the front frame 32 and the rear frame 34.
A control unit 37 may be provided in the display unit 35. The control unit 37 may control the display unit 35. The control unit 37 may include a control part that controls the indoor unit. A vent hole 351 is formed in the rear surface of the display unit 35, thereby circulating air into the display unit 35.
The control unit 37 may be located at one side of the display unit 35. The control unit 37 may be combined with the back surface of the display unit 35. The area of the control unit 37 viewed from the rear may be smaller than the area of the display unit 35.
The display unit 35 may be located at a position overlapping the suction portion 15 in the rotation axis direction of the blower 14. The suction part 15 may be located at the rear of the display unit 35.
The control unit 37 may be located at a position overlapping the suction portion 15 in the rotation axis direction of the blower 14. The suction portion 15 may be located at the rear of the control unit 37.
When the display unit 35 and the control unit 37 are located further forward than the suction unit 15, and the control unit 37 is overheated and the blower 14 is operated, the air flowing in through the air gap 70 is discharged to the discharge unit through the suction unit 15. Thereby, the air of the air gap 70 flows in through the suction portion 15, thereby increasing the heat exchange efficiency by increasing the flow rate and flow amount of the air flowing into the air gap 70.
The suction portion 15 may be located at a face of the case 10 facing the display panel 30. The suction portion 15 may be located at the front surface of the case 10. Specifically, as described above, the suction portion 15 is formed in the front panel 20 forming the front surface of the casing 10.
The air gap 70 may be defined by a gap between the display panel 30 and the case 10. The air gap 70 provides a space through which external air flows in, exchanges heat with the display unit 35, and flows out to the outside through the air gap 70.
The air gap 70 may have a structure in which air heated by the display unit 35 or/and the control unit 37 flows by convection.
The display panel 30 and the case 10 may be completely separated from each other, but it is also possible that the display panel 30 is in contact with a part of the area of the case 10. Thus, the air gap 70 between the display panel 30 and the cabinet 10 may define a flow path that is open at least at the upper and lower portions.
Preferably, the air gap 70 between the display panel 30 and the cabinet 10 may define at least upper, lower, left and right open flow paths.
For example, the air gap 70 may include: a first air gap 71 located at a lower position than the display unit 35; a second air gap 72 located at a higher position than the display unit 35; and a third air gap 73 communicating with the first air gap 71 and the second air gap 72.
Of course, the first air gap 71 may be located at a lower position than the control unit 37, the second air gap 72 may be located at a higher position than the control unit 37, and at least a portion of the third air gap 73 is located at the same height as the control unit 37.
The first air gap 71 is a space between the lower end of the display panel 30 and the lower end of the case 10, the second air gap 72 is a space between the upper end of the display panel 30 and the upper end of the case 10, and the third air gap 73 is a space between the center of the display panel 30 and the center of the case 10.
The outside air flows in through the first air gap 71 and exchanges heat with the display unit 35 and/or the control unit 37 at the third air gap 73, and then flows out through the second air gap 72.
The third air gap 73 may be located at a position overlapping the display unit 35 in the horizontal direction. The third air gap 73 is located behind the display unit 35.
The suction portion 15 may be in communication with the air gap 70. When the air gap 70 and the suction portion 15 communicate, the outside air naturally flows from the suction portion 15 through the air gap 70 during the cooling operation of the indoor unit, and therefore, the cooling capacity is improved by increasing the flow rate and the flow velocity of the air flowing through the air gap 70, and even when only the blower 14 rotates at a low speed, the flow velocity and the flow velocity of the air flowing through the air gap 70 can be increased.
That is, when the suction portion 15 communicates with the air gap 70, the display unit 35 and the control unit 37 can be cooled at the same time of the cooling action.
Specifically, the suction portion 15 may be located at a position overlapping at least with the third air gap 73 in the front-rear direction. The suction portion 15 may be located behind the third air gap 73.
When the control unit 37 is overheated and the blower 14 is operated or the cooling operation is performed, the air flowing in through the air gap 70 is discharged from the discharge portion through the suction portion 15 when the third air gap 73 is located further forward than the suction portion 15.
Accordingly, the air heat-exchanged with the display unit 35 at the air gap 70 flows in through the suction portion 15, thereby improving heat exchange efficiency.
The back surface of the display panel 30 is exposed to the air gap 70. One side of the display unit 35 may be exposed to the air gap 70. Specifically, the back surface of the display unit 35 may be exposed to the air gap 70. The back surface of the display unit 35 may be the widest surface among the surfaces of the display unit 35.
One face of the control unit 37 may be exposed to the air gap 70. Specifically, the back surface of the control unit 37 may be exposed to the air gap 70. The back surface of the control unit 37 may be the widest surface among the surfaces of the control unit 37. Since the widest facing air gap 70 of the display unit 35 and the control unit 37 is exposed, the heat exchange efficiency can be maximized.
The control unit 37 generates more heat than the display unit 35, and the heat is concentrated in the control unit 37. Accordingly, the indoor unit of the air conditioner according to an embodiment of the present invention may further include an air guide 300 guiding or concentrating the air flowing at the air gap 70 to the control unit 37.
For example, the air guide 300 may include a first air guide 310 and a second air guide 320 configured to face the first air guide 310.
The control unit 37 is located between the first air guide 310 and the second air guide 320. The first air guide 310 and the second air guide 320 are formed to protrude from one surface of the display unit 35. Specifically, the first air guide 310 and the second air guide 320 may protrude rearward from the rear surface of the display unit 35.
An acceleration flow path 74 may be defined between the first air guide 310 and the second air guide 320. The air guide 300 may have a shape in which the lower and upper sides of the control unit 37 are opened, and the left and right sides of the control unit 37 are blocked.
The first air guide 310 may be located at the left side of the control unit 37 and have a longer up-down direction length than the control unit 37. The second air guide 320 may be located at the right side of the control unit 37 and have a longer up-down direction length than the control unit 37.
A part of the areas of the first air guide 310 and the second air guide 320 are located at positions overlapping the control unit 37 in the left-right direction, and the first air guide 310 and the second air guide 320 are located at positions not overlapping the control unit 37 in the up-down direction.
The air flowing in the air gap 70 flows into the space between the first air guide 310 and the second air guide 320 and is guided to the control unit 37.
The air guide 300 may be divided into a lower region S1, a central region S2, and an upper region S3. The lower region S1 is a region located at a lower level than the control unit 37, the central region S2 is a region at least a part of which is located at the same level as the control unit 37, and the upper region S3 is a region located at a higher level than the control unit 37.
The interval between the first air guide 310 and the second air guide 320 in the lower region S1 may be wider than the interval between the first air guide 310 and the second air guide 320 in the central region S2.
The portion of the first air guide 310 located in the lower region S1 may be defined as a first lower portion 311, the portion of the second air guide 320 located in the lower region S1 may be defined as a second lower portion 321, the portion of the first air guide 310 located in the central region S2 may be defined as a first central portion 315, the portion of the second air guide 320 located in the central region S2 may be defined as a second central portion 325, the portion of the first air guide 310 located in the upper region S3 may be defined as a first upper portion 313, and the portion of the second air guide 320 located in the upper region S3 may be defined as a second upper portion 323.
Specifically, the interval between the first lower portion 311 and the second lower portion 321 may be wider than the interval between the first center portion 315 and the second center portion 325.
The interval between the first air guide 310 and the second air guide 320 in the lower region S1 may be narrowed as approaching the central region S2. The interval between the first lower portion 311 and the second lower portion 321 may be narrowed as approaching the upper portion from the lower portion. The first lower portion 311 may be inclined upward from the left side toward the right side, and the second lower portion 321 may be inclined upward from the right side toward the left side.
By the arrangement of the first lower portion 311 and the second lower portion 321, the air flowing in from the outside of the air guide 300 is accelerated and the flow rate is increased.
The interval between the first center part 315 and the second center part 325 may be constant in the up-down direction. The interval between the first air guide 310 and the second air guide 320 in the upper region S3 may be wider than the interval between the first air guide 310 and the second air guide 320 in the central region S2.
Specifically, the interval between the first upper portion 313 and the second upper portion 323 may be wider than the interval between the first center portion 315 and the second center portion 325.
The interval between the first air guide 310 and the second air guide 320 of the upper region S3 may be narrowed as approaching the central region S2. The interval between the first upper portion 313 and the second upper portion 323 may be widened as it goes from the lower portion toward the upper portion. The first upper portion 313 may be inclined upward from the right side toward the left side, and the second upper portion 323 may be inclined upward from the left side toward the right side.
By the arrangement of the first upper portion 313 and the second upper portion 323, the flow rate of the air heat-exchanged with the control unit 37 becomes slow, so that the contact time with the display unit 35 increases, and the contact area with the display unit 35 increases.
The air hole 351 may be located between an upper end of the first upper portion 313 and an upper end of the second upper portion 323. A space between an upper end of the first upper portion 313 and an upper end of the second upper portion 323 may overlap the plurality of ventilation holes 351 in a vertical direction. The air hole 351 may be located at an upper portion than between the upper end of the first upper portion 313 and the upper end of the second upper portion 323.
The air discharged from the upper region S3 of the air guide 300 is slowed down and diffused, thereby providing time for flowing into the inside of the display unit 35 through the ventilation holes 351, and thus the heat exchange efficiency is increased.
Of course, the air guide 300 may function as a reinforcing material that reinforces the rigidity of the display unit 35. The air guide 300 prevents twisting and vibration of the display unit 35, and reinforces rigidity of the display unit 35.
The display panel 30 and the case 10 may be moved relative to each other by a link. The links may include a main link 3a and an auxiliary link 3c.
The main link 3a is hinge-coupled to the display panel 30 and the case 10, respectively. The main link 3a may include: a first link 331 having one end hinge-coupled with the case 10; and a second link 332 having one end hinge-coupled to the first link 331 and the other end hinge-coupled to the display panel 30. The length of the second link 332 may be longer than the length of the first link 331. A link motor 3b may be connected to the main link 3 a.
The first link 331 is connected to the case 10 by a first hinge 334, the first link 331 is connected to the second link 332 by a second hinge 333, and the second link 332 is connected to the display panel 30 by a third link 335.
The auxiliary link 3c is hinge-coupled to the display panel 30 and the case 10, respectively. The auxiliary link 3c may be provided with a pair. The main link 3a may be located between a pair of auxiliary links 3 c.
The main link 3a may be located at an upper portion than the auxiliary link 3c, and the total length of the main link 3a may be greater than that of the auxiliary link 3 c.
The display panel 30 includes a hanger 38. The hook 38 allows the display panel 30 to be hung on the hook support portion 210 of the case 10.
For example, the hooks 38 may protrude rearward from the back surface of the display panel 30. Specifically, the hook 38 may include: a first member 381 extending from the front surface of the display panel 30 toward the rear of the display panel 30; and a second member 382 connected downward from the rear end of the first member 381. One end of the second member 382 may be spherically shaped to reduce friction.
The hook 38 may be located at a position spaced apart from the main link 3 a. The hook 38 may be located further down than the main link 3 a.
The hook 38 may be located further down than the suction portion 15. In addition, the hook 38 may be located further to the lower side than the display unit 35.
The case 10 includes a hanger support part 210. The hooking support 210 may protrude forward from the front surface of the case 10. The hook support 210 provides a space for hooking the hook 38.
For example, the hanger supporting part 210 may include an upper hanger supporting part 212 and a lower hanger supporting part 211 located at a lower position than the upper hanger supporting part 212.
The upper hanger supporting part 212 may protrude forward from the front panel 20. The upper hook support 212 does not provide a rotation center during the rotation operation of the display panel 30, but is configured to hold only the hook 38 in a maintenance state, and thus is preferably configured to extend in a horizontal direction for easy hooking and unhooking of the hook 38.
The lower hanger supporting part 211 may include: a first lower hook support portion 211a extending forward from the front panel 20; and a second lower hanger supporting part 211b extending from one end of the first lower hanger supporting part 211a to the upper end.
When the display panel 30 is switched from the opened state to the closed state or vice versa, the lower hook support portion 211 hooks the hooks 38 and becomes the rotation center of the display panel 30, and thus has a structure protruding rearward and bending upward in order to prevent the hooks 38 from being separated.
The lower hanger supporting part 211 of the hanger supporting part 210 may be located adjacent to the lower end of the front panel 20. Specifically, the lower hook support portion 211 of the hook support portion 210 may be located at a lower position than the suction portion 15.
The display panel 30 may include a closed state, an open state, and a maintenance state.
Hereinafter, various states of the display panel 30 will be described.
Fig. 6 is a sectional view showing a closed state of the display panel 30.

In the closed state, the display panel 30 may be entirely overlapped with the case 10 in the front-rear direction, and at least one surface of the display panel 30 may be in contact with at least one surface of the case 10. In addition, in the closed state, the display panel 30 and the case 10 are arranged in parallel. That is, in the closed state, the display panel 30 and the case 10 extend in the horizontal direction.
In the closed state, the hook 38 is hooked on the lower hook support portion 211, and the main link 3a is in a folded state.
In the off state, natural convection is formed or the blower 14 operates at a low speed in order to radiate heat from the display panel 30.
Fig. 7 is a sectional view showing an opened state of the display panel 30.
Referring to fig. 7, the display panel 30 may include an opened state spaced apart from one end of the case 10. In the opened state, the upper end of the display panel 30 may be spaced apart from the upper end of the case 10, and the lower end of the display panel 30 is in contact with the lower end of the case 10.
When the state is changed from the closed state to the open state, the display panel 30 rotates around the lower hook support 211, and the main link 3a is unfolded. In the process of switching from the closed state to the open state, the hook 38 becomes the rotation center of the display panel 30 in a state of being hooked on the lower hook support portion 211.
That is, in the open state, the display panel 30 is inclined with respect to the case 10.
In the open state, the indoor unit performs cooling operation or heating operation.
Fig. 8 is a sectional view showing a maintenance state of the display panel 30, fig. 9 is a front view showing a maintenance state of the display panel 30, and fig. 10 is a sectional view of a portion where the bolt of fig. 9 is located.
Referring to fig. 8 to 10, the display panel 30 may include a maintenance state in which a lower portion of the case 10 is exposed. In the maintenance state, the upper end of the display panel 30 is spaced apart from the upper end of the casing 10, and the lower end of the display panel 30 is located further upward than the lower end of the casing 10.
Accordingly, in the maintenance state, the lower end of the case 10 is exposed forward, and the cover fastening mechanism 810 can be exposed. The cover fastening mechanism 810 will be described later.
That is, the maintenance state is a state in which the display panel 30 in the open state is moved to the upper portion. The hook 38 is hooked to the case 10 in a state where the cover fastening mechanism 810 is exposed.
In the maintenance state, the hooks 38 may be hooked on the upper hook support portions 212, and the lower end of the display panel 30 may be caught on the lower hook support portions 211. Thereby, the display panel 30 is stably placed in the maintenance state.
Since the user may be injured by the blower 14 during cleaning in the maintenance state, the blower 14 is stopped.
A lower cover 43 is disposed on the second discharge portion 16c formed on the bottom surface of the casing 10. The lower cover 43 may be coupled to the case 10 by a cover fastening mechanism 810.
The cover fastening mechanism 810 may penetrate the case 10 and fasten the cover and the case 10. For example, the cover fastening mechanism 810 may include bolts.
The cover fastening mechanism 810 may be located adjacent to the lower end of the case 10. The cover fastening mechanism 810 may be located at a lower position than the hook support 210. By the cover fastening mechanism 810 being located at a lower position than the hook support portion 210, the cover fastening mechanism 810 is exposed when the hook 38 is hooked on the hook support portion 210. The case 10 may include bolt holes 231 for fastening the cover fastening mechanism 810.
The lower cover 43 may include a fastening tab 449, the fastening tab 449 including a through opening through which the cover fastening mechanism 810 extends.
Fig. 11 is a diagram showing a state in which the lower cover 43 is removed in the maintenance state of the display panel 30.
Referring to fig. 11, in the maintenance state of the display panel 30, the lower cover 43 may be separated after the cover fastening mechanism 810 is separated. When the lower cover 43 is removed in the maintenance state of the display panel 30, the blower 14 is exposed through the second discharge portion 16 c. Thus, at least a part of the blower 14 can be positioned vertically overlapping the second discharge portion 16 c.
Of course, the side frames 36 may be removed in the maintenance state of the display panel 30 or before switching to the maintenance state of the display panel 30.
The structure of the lower cover 43 will be described in detail below.
Fig. 12 is a plan view showing the lower cover 43 of an embodiment of the present invention, and fig. 13 is a perspective view showing the lower cover 43 of an embodiment of the present invention.
Referring to fig. 12 and 13, the lower cover 43 may have a structure to be attached to and detached from the case 10 and a structure to be fastened to the cover fastening mechanism 810.
For example, the lower cover 43 includes: a cover 441 coupled to the case 10; and a cover opening 443 formed through the cover plate 441 and located at a position corresponding to the second discharge portion 16c, for discharging air discharged from the second discharge portion 16 c.
The cover 441 may cover at least the second discharge portion 16c. Preferably, the cover plate 441 may have a shape and size corresponding to each side of the base 12, and covers the lower side of the base 12.
The cover 441 may have a coupling element coupled to the base 12. The coupling element may comprise a cover hook. The cover hook is inserted into the case 10. The cover hook may include: a first cover hook 445 at one end of the cover plate 441; and a second cover hook 446 at the other end of the cover plate 441.
The lower cover 43 may also include a fastening tab 449, the fastening tab 449 including a through opening through which the cover fastening mechanism 810 extends. The fastening piece 449 extends from the cover plate 441 toward a direction intersecting the cover plate 441.
Fig. 14 is a control block diagram of an embodiment of the present invention.
Referring to fig. 14, the present invention may further include a temperature sensor 525, a humidity sensor 530, a cover separation sensing sensor 550, and a control part 560.
The temperature sensor 525 may be provided at the case 10. Specifically, the temperature sensor 525 may be provided at a position adjacent to the left discharge portion 16a or the right discharge portion 16 b. The temperature sensor 525 supplies temperature information to the control portion 560.
The cover separation sensing sensor 550 may be provided at the case 10. Specifically, the cover separation sensing sensor 550 may be disposed adjacent to the second discharge portion 16c of the casing 10. The cover separation sensing sensor 550 senses whether the lower cover 43 is separated or not, and provides the information to the control part 560. The cover separation sensing sensor 550 may be constituted by an optical sensor or a switching sensor.
The humidity sensor 530 may be provided at the cabinet 10. Specifically, the humidity sensor 530 may be disposed adjacent to the left discharge portion 16a or the right discharge portion 16 b. The humidity sensor 530 provides the relative humidity information to the control unit 560.
In the case where the separation of the cover from the case 10 is sensed by the cover separation sensing sensor 550, the control part 560 may control to stop the blower 14. This prevents the user from performing cleaning while the blower 14 is rotating due to carelessness during cleaning.
In addition, the control part may control the vane motor 520 to open the discharge part in case that the separation of the cover from the casing 10 is sensed. When the cover is separated from the casing 10, the blower 14 can be exposed through the second discharge portion 16c by opening the regulating blade 510.
The control unit 560 may determine the condensation dew condensation condition based on the temperature and humidity around the casing 10 and the rotation speed of the fan motor 14a, and control the vane motor 520 to adjust the vane 510 to close the second discharge unit 16c when the condensation dew condensation condition is satisfied.
When the second discharge portion is closed by the regulating vane 510 under dew condensation conditions, the flow rate of air discharged from the first discharge portions 16a, 16b increases, and dew condensation can be prevented in the first discharge portions 16a, 16b and the second discharge portion 16 c.
The control unit 560 may determine that the dew condensation condition is satisfied when the temperature around the casing 10 is within a predetermined temperature range, the humidity around the casing 10 is equal to or higher than a predetermined reference humidity, and the rotational speed of the fan motor 14a is lower than the reference speed.
In addition, in the case where the condensed dew condition is satisfied, the control part 560 may increase the rotation speed of the fan motor 14a to be higher than the current rotation speed. When the rotational speed of the fan motor 14a is higher than the current rotational speed in the case where the dew condensation condition is satisfied, the control unit 560 can prevent dew condensation at the discharge unit 16.
In addition, when the temperature of the control unit 37 is higher than the critical temperature, the control part 560 may control the fan motor 14a to rotate the blower 14. When the temperature of the control unit 37 is higher than the critical temperature, the control unit 560 may control the fan motor 14a to rotate the blower 14 at a lower rotational speed than during normal operation.
Hereinafter, a control method for preventing injury to a user when separating a cover according to the present invention will be described in detail.
Fig. 15 is a flowchart showing a control method of an embodiment of the present invention.
Referring to fig. 15, the cap separation sensing sensor 550 senses the separation of the cap and provides it to the control part 560 (S105).
The control part 560 determines whether the cover is separated or not based on the information input from the cover separation sensing sensor 550 (S110).
When it is determined that the cover has been separated, the control unit 560 turns off the power to the fan motor 14a to stop the rotation of the blower 14 (S120).
When it is determined that the cap has been separated, the control unit 560 controls the vane motor 520 to open the regulating vane 510 to the second discharge unit 16c (S130). The indoor unit of the present invention has one or more of the following effects.
First, according to the present invention, when the display panel is in the maintenance state, the lower portion of the case is exposed, and when the bolts coupled to the lower portion of the case are separated, the cover covering the lower discharge portion can be removed, and the blower is exposed through the lower discharge portion, so that there is an advantage that the blower can be easily cleaned through the lower discharge portion by using a cleaning brush or the like, and there is an advantage that the blower can be cleaned simply by lifting the maintenance panel, separating the bolts, separating the lower cover.
In the second aspect, according to the present invention, since the hook formed on the display panel is hooked on the casing in the maintenance state where the lower portion of the casing is exposed on the display panel, there is an advantage in that the display panel does not need to be separated during cleaning, and the indoor unit can be easily cleaned even by the elderly and infirm.
Third, according to the present invention, the case includes two supporting parts with steps, and in a maintenance state of the display panel, the hooks of the display panel are respectively hooked at the two supporting parts at the lower end of the display panel, so that there is an advantage in that the display panel can be stably placed in the maintenance state.
Fourth, according to the present invention, there is an advantage in that the hooks of the display panel are hooked at the case in the closed state and the open state of the display panel, thereby stably fixing the display panel, and the hooks of the display panel become the rotation center in the process of switching from the closed state to the open state of the display panel.
Fifth, according to the present invention, since the inclination angle of the back surface of the discharge portion is made gentler than the discharge guide, the conversion is made softer when the direction of the air is converted by the discharge guide at the discharge portion, and the flow rate of the air discharged through the discharge portion is increased, the air discharged through the discharge portion has a uniform velocity, and thus there is an advantage in that dew condensation around the discharge portion is prevented.
In the sixth aspect of the present invention, since the discharge guide on the same surface as the rear surface of the discharge portion is composed of a portion having the same inclination angle as the rear surface of the discharge portion and a portion having a larger inclination angle than the rear surface of the discharge portion, the switching is made softer when the discharge portion switches the direction of air by the discharge guide, and dew condensation on the rear surface of the discharge portion is prevented, dew condensation on the wall surface adjacent to the rear surface of the discharge portion is prevented because the discharge guide can be kept at a larger angle toward the front surface on the rear surface of the discharge portion.
The above-described features, configurations, effects, etc. are included in at least one embodiment of the present invention, and should not be limited to only one embodiment. Furthermore, those skilled in the art can combine or modify the contents of each embodiment with other embodiments. Accordingly, matters related to these combinations and modifications are to be understood as being included within the scope and spirit of the invention as disclosed in the accompanying claims.
