JP-A-10-246465

  When cool air conditioned by air is blown out from the indoor air outlet, the inner wall surface of the indoor air outlet and the front plate of the surrounding frame are cooled to a low temperature. The low-temperature air blown out by the indoor blower entrains the surrounding indoor air and creates a swirling air flow around the indoor air outlet, which is the indoor air before dehumidification. If you touch the low-temperature part around the water, water vapor in the air will condense.

  If the indoor air outlet is configured vertically, if condensation occurs at the periphery of the indoor air outlet, if any one of the attached water droplets starts to flow downward due to gravity, the water droplets gather and suddenly increase in size. Eventually, it becomes a trouble that condensed water drops from the lower end of the indoor air outlet through the frame front plate to the room. For this reason, the receiving tray which collect | recovers condensed water is provided in the lower part of an indoor air blower outlet, and the structure which collect | recovers and processes the condensed water which flows through an indoor air blower outlet is needed. On the other hand, even if such a trouble occurs at the time of high humidity such as at the start of operation, if the air conditioner is operated and the dehumidification in the room proceeds, the trouble will stop naturally, so any measures are taken. Some are not.

  In addition, since the indoor air outlet and the indoor air inlet are located adjacent to the front of the frame, a phenomenon called a short circuit occurs in which the air blown from the indoor air outlet is sucked into the indoor air inlet. It is easy to do. Conventional measures for this need to prevent cold air from flowing to the indoor air inlet adjacent to the indoor air outlet, and those equipped with a variable louver have no indoor air inlet from the front of the frame. The blowing direction is set to be variable between the diagonally forward sides. Since the blowing direction of the cold air is limited in this way, the cold air can reach only a certain range, and when the indoor air outlet is located on the side close to the indoor wall, The wind could not be blown out in the direction in which the air is present, and a great difference in usability occurs depending on the position where the air conditioner is installed.

  In recent years, the cost of materials has been rising and production costs tend to increase. Therefore, there is an increasing demand for cost reduction. In the conventional one, the evaporator on the indoor side is provided at a position facing the air suction port on the front surface of the frame, so the evaporator and the capacitor are installed at positions separated from each other, and the arrangement efficiency of the parts in the frame is poor. There are challenges. Therefore, in order to meet the demand for cost reduction, the compressor, evaporator, and condenser can be arranged together as compactly as possible, and the components such as the refrigerant piping and heat insulating material that connect the compressor, evaporator, and condenser have a compact shape. There is a need to reduce the material costs of the construction and use.

  The present invention solves the above problems, and the frame 1 includes an indoor blower 2, an outdoor blower 3, a compressor 4, a condenser 5 and an evaporator 6 constituting a refrigeration cycle, and the frame 1 Is provided with a front panel 1a on the indoor side, a rear panel 1b facing the outdoor side, and a partition wall 7 that divides the inside of the frame 1 into two chambers. The front panel 1a has an indoor air inlet 8 and an indoor air blower. The evaporator 6 and the indoor blower 2 are disposed in an indoor air flow path 10 that is disposed with an outlet 9 and is partitioned by the partition wall 7 and communicates from the indoor air inlet 8 to the indoor air outlet 9. In the rear panel 1b, an outdoor air inlet 11 and an outdoor air outlet 12 are arranged, and are partitioned by the partition wall 7 to communicate with the outdoor air outlet 12 from the outdoor air inlet 11. In the above The denser 5 and the outdoor blower 3 are arranged, the refrigerant compressed to high temperature and high pressure by the compressor 4 is liquefied by the condenser 5, and the liquefied refrigerant is vaporized by the evaporator 6 and passes through the indoor air passage 10. In a window air conditioner that cools indoor air, the indoor air intake port 8 is formed in a vertically long side surface of the front panel 1 a, and the evaporator 6 is connected to the partition wall 7 in the indoor air channel 10. A fan that is disposed so as to face each other with an interval 14 therebetween, and the indoor blower 2 is disposed on the front side of the evaporator 6, and an air flow that surrounds the interior of the indoor blower 2 toward the indoor air outlet 9. A case 15 is formed, and the fan case 15 is arranged such that an air inlet 15a communicating with the indoor air flow path 10 is disposed in front of the evaporator 6, and the indoor air blowing 9 is formed horizontally on the upper surface of the front panel 1 a to connect the outlet 15 b of the fan case 15, and an air flow from the indoor air inlet 8 toward the space 14 is formed in the indoor air flow path 10. The air sent to the interval 14 passes through the evaporator 6, flows into the fan case 15, is directed upward by the blower fan 2, and is blown out from the indoor air outlet 9. To do.

  The indoor air flow path 10 is formed with an air flow gap 10a between the side surface of the front panel 1a and the side surface of the fan case 15, and the indoor air intake port provided on the side surface of the front panel 1a. Since 8 faces the evaporator 6 and the air flow gap 10a, a space for forming the indoor air inlet 8 can be secured without increasing the depth of the frame 1.

  Further, a U-shaped connection pipe 6a is provided on a side surface of the evaporator 6, and the evaporator 6 is disposed in the indoor air flow path 10 so that the connection pipe 6a faces the indoor air intake port 8, The air flowing into the indoor side air flow path 10 from the indoor air intake port 8 passes through the periphery of the connection pipe 6a and travels toward the interval 14, so that the entire evaporator 6 can exchange heat with the indoor air. .

  In addition, a partition plate 16 is provided below the indoor air flow path 10 to form a lower space 17 partitioned from the indoor air flow path 10, and the compressor 4 and the air are formed in the lower space 17. The control board 18 of the harmony machine is arranged, the evaporator 6 and the compressor 4 are arranged close to one side of the frame 1, and the control board 18 is arranged on the other side of the lower space 17, and the control board 18 is arranged on the front side of the frame body 1 from the evaporator 6 so as to face the front surface or side surface of the front panel 1a, so that the control board 18 is separated from the direction in which drain water from the evaporator 6 drops. Can be placed.

  Since the fan case 15 is disposed at a higher position than the partition plate 16 and a gap 19 is formed between the bottom surface of the fan case 15 and the partition plate 16, the partition plate 16 is caused by cold air flowing through the fan case 15. No influence and no condensation.

  The air conditioner of the present invention is configured such that a horizontally long indoor air outlet 9 is formed on the upper surface of the front panel 1a of the frame body 1 and cool air is blown out from the upper front of the frame body 1. The cool air blown out from the room flows from the high place in the room to the floor surface while spreading in the horizontal direction, so that the cool air is easily circulated throughout the room and the cooling effect can be improved. Further, since the indoor air intake port 8 is arranged on the side surface of the front panel 1 a and the indoor air on the side of the frame body 1 is sucked in, the cool air blown from the indoor air outlet 9 changes the direction of the indoor air intake port 8. It is possible to greatly widen the blowing angle without facing, and even when the frame 1 is installed so as to approach the wall, the blowing direction of the cold air can be surely directed to the center of the room. The cold air no longer flows along the air conditioner, and the installation conditions of the air conditioner can be relaxed.

  Even if condensation occurs at the periphery of the indoor air outlet 9, water droplets remain attached to the indoor air outlet 9 or drop into the frame 1 and travel through the indoor air outlet as before. Therefore, there is no worry of water droplets dropping into the room. Furthermore, since the indoor air outlet 9 is located at a high place in the room, it is possible to prevent a hand or a foreign object from being inserted through the indoor air outlet 9.

  Further, the compressor 4, the condenser 5 and the evaporator 6 can be arranged near the partition wall 7 in the frame body 1, and the members such as the refrigerant piping and the heat insulating material connected to the compressor 4, the condenser 5 and the evaporator 6 are compact. Since the material cost of the parts used can be suppressed, the production cost can be reduced.

  The indoor air flow path 10 forms an air circulation gap 10a between the side surface of the front panel 1a and the side surface of the fan case 15, and the indoor air inlet 8 on the side surface of the front panel 1a faces the air circulation gap 10a. By forming also in the position which carries out, the opening area of the indoor air inlet 8 can be ensured, without expanding the depth dimension of the frame 1. FIG. For this reason, it is not necessary to change the depth dimension of the frame 1, and the installation structure of the air conditioner remains unchanged, and the cold air blown from the indoor air outlet 9 is directed to the indoor air inlet 8 without changing the conventional structure. An air conditioner that does not generate air can be realized.

  Further, a U-shaped connection pipe 6a is provided on the side surface of the evaporator 6, and the refrigerant flows through the connection pipe 6a. For this reason, by arranging the connection pipe 6a of the evaporator 6 in the indoor air flow path 10 so that the connection pipe 6a faces the indoor air intake port 8, the air flowing into the air circulation gap 10a from the indoor air intake port 8 becomes the interval 14. Since it passes through the periphery of the connection pipe 6a when heading, heat exchange is also performed in the U-shaped connection pipe 6a portion of the evaporator 6, and heat exchange is possible in the entire evaporator 6, so heat exchange efficiency is improved. It became a thing.

  Further, a partition plate 16 is provided below the indoor air flow path 10 to form a lower space 17 partitioned from the indoor air flow path 10, and the compressor 4 is installed near one side of the lower space 17. The control board 18 of the air conditioner is arranged on the other side, and the control board 18 is located on the front side of the frame body 1 with respect to the evaporator 6 of the indoor air flow path 10, and the front or side surface of the front panel 1a. It is attached so as to face each other. Since the drain water dripped from the evaporator 6 is guided to the outdoor side and does not cause dew condensation on the surface of the front panel 1a, the control board 18 can be arranged away from the direction in which the drain water from the evaporator 6 is processed. As a result, the waterproofing measures for the control board 18 can be simplified, and production costs can be reduced and maintenance can be improved.

  Further, since the cool air after passing through the evaporator 6 flows through the fan case 15, the surface temperature of the fan case 15 may decrease and condensation may occur. In the present invention, the fan case 15 is separated from the partition plate 16. Since it is arranged at a high place, a gap 19 is formed between the bottom surface of the fan case 15 and the partition plate 16, and the partition plate 16 is not in contact with the fan case 15 and is not directly cooled by the fan case 15. There is no condensation on the surface of the partition plate 16, the vicinity of the control board 18 disposed in the lower space 17 below the partition plate 16 is not affected by condensation due to cold air, and the waterproof structure of the control board 18 can be simplified. Therefore, reduction of production cost and improvement of maintainability can be expected.

The liquid refrigerant is then sent to the evaporator 6 and vaporized, and the indoor air in the indoor air passage 10 is cooled by the heat of vaporization at this time. Then, the refrigerant vaporized by the evaporator 6 is sent again to the compressor 4 and compressed and sent to the condenser 5 to constitute a refrigeration cycle.

  The air conditioner for windows has a vertically long frame shape that cannot be installed on the window frame, and the indoor air channel 10 and the compressor 4 are arranged vertically in the frame 1. Is done. Reference numeral 16 denotes a partition plate which is disposed between the compressor 1 and the indoor air flow path 10 and divides the inside of the frame body 1 vertically. Reference numeral 17 denotes a lower space formed below the partition plate 16. Is installed in the lower space 17.

The water channel 20 a passes through the partition wall 7 and reaches the condenser 5 of the outdoor air channel 13. When indoor air passes through the evaporator 6, moisture contained in the air is condensed and adheres to the surface of the evaporator 6, becomes drain water, drops onto the drain receiver 20, and the drain water dropped on the drain receiver 20 is guided. It flows through the water channel 20a and is guided to the capacitor 5.
Reference numeral 21 denotes a lower drain receiver disposed below the condenser 5. The lower drain receiver 21 is formed on the base 1c of the frame body 1 outside the partition wall 7, and the drain water guided by the water conduit 20a is stored in the condenser. 5, the drain water partly evaporates with the heat of the condenser 5 to become water vapor and is discharged from the outdoor air outlet 12 to the outside. It collects in the drain receptacle 21.

  The lower drain receiver 21 is provided with a rotating plate (not shown), and the rotating plate is located in the drain water stored in the drain receiver. When the rotating plate rotates, the drain water of the lower drain receiver 21 is scooped up. Water is sprinkled on the condenser 5. The drain water adhering to the condenser 5 is evaporated by the heat of the condenser 5 to become water vapor, and is discharged to the outside from the outdoor air outlet 12. The drain water is evaporated by the condenser 5, so that the drain water in the lower drain receiver 21 is discharged. Can be processed without draining. In addition, since the condenser 5 is cooled by applying drain water to the condenser 5, the cooling efficiency of the refrigerant is improved, and an improvement in cooling capacity can be expected.

Since a general window air conditioner has a vertically long frame shape that cannot be taken large enough to be placed on the window frame, the indoor air inlet and the indoor air outlet are arranged on the front of the front panel of the frame. It has been thought that it must be placed adjacent to. For this reason, it is necessary to prevent the cool air blown out from the indoor air outlet from being directed to the indoor air intake port. The blowing direction can only be changed between the two.
Since it is such a configuration, the cool air blown out from the vertically long indoor air outlet has little spread in the lateral direction, and the air blown from the indoor air outlet is limited to a narrow range. When installed close to each other, the cold air easily flows along the wall and does not circulate quickly in the room, and the temperature unevenness in the room tends to increase.

  The present invention realizes an unprecedented new arrangement structure for indoor air inlets 8 and indoor air outlets 9 even for a window air conditioner having a vertically long frame shape. In order to realize a simple arrangement structure, the blower structure in the frame 1 is specified.

  In the present invention, the indoor air suction port 8 is formed vertically long on the side surface of the front panel 1a on the front side of the partition wall 7 of the frame 1, and the indoor air outlet 9 is formed on the upper surface of the front panel 1a. ing. Although the indoor air intake port 8 of the embodiment is formed on both side surfaces of the front panel 1a, the indoor air intake port 8 may be provided only on one side surface of the front panel 1a if an air flow can be secured.

  The evaporator 6 is arranged side by side with the outdoor fan 3 of the outdoor air flow path 13 so as to be close to one side in the indoor air flow path 10, and 14 is an interval formed between the evaporator 6 and the partition wall 7. The evaporator 6 is disposed so as to face the partition wall 7 with an interval 14.

The indoor blower 2 is composed of a sirocco fan, the indoor blower 2 is arranged on the front side of the evaporator 6, 15 is a fan case constituting a blower casing formed so as to surround the indoor blower 2, and 15a is a room The air inlet of the fan case 15 communicating with the inside air flow path 10 and the fan case 15, 15 b is the outlet of the fan case 15 connected to the indoor air outlet 9, and 2 a is in the center of the air inlet 15 a of the fan case 15. When the motor 2a is energized and the indoor fan 2 rotates, air is sucked from the indoor air inlet 15a and an air flow toward the outlet 15b is formed.
Reference numeral 15 c denotes an air guide member provided around the air inlet 15 a of the fan case 15, and the fan case 15 is connected to the front surface of the evaporator 6 so that the air inlet 15 a faces the evaporator 6. The outlet 15b of the fan case 15 is directed upward and connected to an indoor air outlet 9 provided on the upper surface of the front panel 1a.
In this configuration, when the indoor blower 2 rotates, room air flows from the indoor air intake port 8 on the side surface of the front panel 1 a into the indoor air channel 10, and enters the indoor air channel 10 from the indoor air intake port 8. An air flow directed to the interval 14 is created, and the air sent to the interval 14 faces the front side of the frame body 1, passes through the evaporator 6, and flows into the fan case 15 from the air inlet 15 a through the air guide member 15 c. Then, an upward air flow is formed in the fan case 15, and blows out from the indoor air outlet 9 into the room through the outlet 15 b of the fan case 15.

  In this configuration, since the indoor air outlet 9 is configured to be laterally long so as to be substantially the entire width of the frame body 1, cold air can be blown out from the entire indoor air outlet 9 configured to be wide. It became possible to blow cold air over a wide area in front of the body 1. Further, since the indoor air outlet 9 is located near the ceiling of the room, the cool air flows from the vicinity of the ceiling of the room toward the floor. For this reason, the cool air does not immediately flow near the floor surface, but spreads in front of the air conditioner and easily reaches a far range away from the air conditioner, so that the cool air circulates in the room quickly.

  Moreover, in this structure, the indoor air blower 2 in the indoor side air flow path 10 is located ahead of the evaporator 6, and the indoor air outlet 9 provided in the upper surface of the front panel 1a is also located in the frame body 1 front side. Therefore, the cool air blown from the indoor air outlet 9 does not go to the side of the frame 1 but goes to the front of the front of the frame 1. And since the indoor air inlet 8 is arrange | positioned at the side surface of the front panel 1a, and the air of the side of the frame 1 is sucked in, the cold air which blows off from the indoor air outlet 9 is not sucked into the indoor air inlet 8, The short circuit phenomenon no longer occurs.

  Reference numeral 9a denotes a louver provided at the indoor air outlet 9, which can change the blowing direction of the cold air vertically and horizontally. In the present invention, even when the blowing direction of the cold air is changed to the left and right by the louver 9a and is directed obliquely forward of the frame body 1, the cold air does not go to the side of the frame body 1, and the cold air is directed to the side of the front panel 1a. Since it is not sucked into the indoor air inlet 8 provided, the blowing angle of the louver 9a can be set in a wide range in front of the frame body 1.

  For this reason, when the side surface of the frame 1 is installed close to the indoor wall surface, the cold air blown out from the indoor air outlet 9 by the louver 9a is opposite to the indoor wall surface without causing a short circuit phenomenon. Because the cool air circulates quickly in the room regardless of whether the frame 1 is closer to the left or right wall in the room, the temperature unevenness in the room can be reduced. The cooling effect can be improved without generating.

  Moreover, since the evaporator 6 is arrange | positioned rather than the indoor air blower 2 at the partition wall 7 side, the evaporator 6 does not oppose the front panel 1a, but is located in the frame 1 away from the front panel 1a, and the evaporator 6, the condenser 5, and the compressor 4 can be arranged in the vicinity of the partition wall 7 in the frame 1. Therefore, the compressor 4, the condenser 5, and the evaporator 6 can be placed close together in a compact manner in the frame 1. Can do.

  Conventionally, the evaporator is arranged along the inside of the front panel so as to face the indoor air inlet, and the drain receiver and the refrigerant pipe are also arranged along the inside of the front panel. In addition, since there is a possibility of causing condensation on the surface of the front panel due to the cold air of the refrigerant pipe, it is necessary to attach a heat insulating material to the refrigerant pipe. However, since the evaporator and the condenser are arranged at positions separated from each other in the front and rear of the frame body, the length of the refrigerant pipe is required, the shape of the drain receiver and the heat insulating material is increased, and many materials are used for these parts. Necessary, leading to an increase in production costs.

  In the present invention, since the distance between the evaporator 6 and the condenser 5 can be shortened, the drain receiver 20 and the water conduit 20a can be configured in a compact shape, and the refrigerant pipe 4a can be connected to the partition wall 7 in the frame 1. Since it can arrange | position collectively in the vicinity, the length of the refrigerant | coolant piping 4a can be shortened, and the structure can be simplified. Furthermore, since the refrigerant pipe 4a can be arranged in the frame 1 that does not face the front panel 1a, there is no concern about condensation on the surface of the front panel 1a due to the cold air of the refrigerant pipe 4a, and the condensation prevention that has been attached to the refrigerant pipe 4a. Since the amount of the heat insulating material used can be reduced, the material cost for the refrigerant pipe 4a and the heat insulating material can be suppressed, and the cost can be reduced.

  The air conditioner assembly procedure is as follows. After the compressor 4, condenser 5 and evaporator 6 constituting the refrigeration cycle are attached to the frame 1 and the refrigerant pipe 4a is connected, the components such as the indoor blower 2 and the outdoor blower 3 are attached. It is to be attached. In this invention, since the evaporator 6 is disposed inside the frame body 1 closer to the partition wall 7 than the indoor blower 2, even if the evaporator 6 is first attached to the frame body 1, the installation work of the indoor blower 2 is obstructed. The workability can be improved. Furthermore, the indoor blower 2 and the motor 2a can be integrally formed in advance by the fan case 15, and it is sufficient to attach the fan case 15 together with the front surface of the evaporator 6, and the indoor blower 2 and the motor 2a on the assembly line can be installed. Since attachment work is not necessary, productivity can be improved and production cost can be reduced.

Moreover, since cool air blows out from the indoor air outlet 9, the inner wall surface of the indoor air outlet 9 and the surface of the front panel 1a of the frame 1 in the vicinity thereof are cooled to a low temperature. And if the indoor air before dehumidification around the indoor air outlet 9 touches the indoor air outlet 9 and the low temperature part around it, dew condensation occurs. In the present invention, since the indoor air outlet 9 is provided on the upper surface of the front panel 1a, water droplets adhering to the inner wall surface of the indoor air outlet 9 flow into the frame 1 through the fan case 15, and the dew condensation water flows. It no longer flows along the surface of the front panel 1a, and there is no worry of dripping into the room.
Condensation is likely to occur when the air conditioner starts operating at high humidity. However, if indoor dehumidification progresses over time, the occurrence of condensation at the indoor air outlet 9 and its surroundings can be suppressed. The condensed water does not collect in the fan case 15.

  Furthermore, since the indoor air outlet 9 is located at a high place in the room, the hand cannot reach the indoor air outlet 9, so that an effect of preventing a child's mischief such as inserting a hand or a foreign object can be expected. became.

  In addition, the conventional air conditioner for windows has a similar design because the indoor air inlet and the indoor air outlet are disposed adjacent to each other on the front surface of the frame. Since the machine is not provided with the indoor air inlet 8 and the indoor air outlet 9 on the front surface of the front panel 1a of the frame body 1, the degree of freedom in designing the front surface of the front panel 1a is widened, and the design can be differentiated. It is now possible.

  Reference numeral 10a denotes an air flow gap formed between the side surface of the front panel 1a of the frame body 1 and the side surface of the fan case 15 with the lateral width of the fan case 15 shorter than the lateral width of the frame body 1. The indoor air inlet 8 on the side surface 1a is also formed at a position facing the air circulation gap 10a. In this way, the indoor air flows from the indoor air inlet 8 into the air circulation gap 10a, and an air flow toward the interval 14 along the side surfaces of the fan case 15 and the evaporator 6 can be formed. The opening area of the indoor air inlet 8 can be ensured without increasing the length. For this reason, it is not necessary to change the depth dimension of the frame 1, and a new arrangement structure can be realized even with a window air conditioner that cannot take a large depth dimension.

Reference numeral 6a denotes a U-shaped connecting pipe formed on the side surface of the evaporator 6. The evaporator 6 has a large number of flat fins arranged in the vertical direction with small gaps and a plurality of pipes arranged in the horizontal direction. And a U-shaped connection pipe 6a that alternately connects ends of a plurality of pipes, and the indoor air intake port 8 provided on the side surface of the frame 1 with the U-shaped connection pipe 6a of the evaporator 6 It is arrange | positioned at the indoor side air flow path 10 so that it may face.
In this way, since the indoor air flowing in from the indoor air intake port 8 flows around the U-shaped connection pipe 6a when flowing from the air circulation gap 10a toward the interval 14, the U-shaped connection pipe 6a. The air touched by the air is cooled, and heat exchange can be performed not only in the central portion of the evaporator 6 through which the room air passes but also in the connection pipe 6a. Furthermore, since the evaporator 6 and the indoor blower 2 are disposed so as to face each other, the indoor air can be uniformly passed through the entire evaporator 6. For this reason, heat exchange can be performed by the whole evaporator 6, and the air conditioner excellent in heat exchange efficiency can be realized.

Reference numeral 18 denotes a control board for instructing operation / stop of the indoor blower 2, the outdoor blower 3, the compressor 4, etc. The control board 18 is arranged in the lower space 17 of the frame 1. The evaporator 6 in the indoor air flow path 10 is arranged close to one side of the frame 1, and the compressor 4 in the lower space 17 is arranged close to one side of the frame 1 so as to be positioned below the evaporator 6 side. The control board 18 is disposed on the opposite side of the compressor 4 and on the front side of the frame 1 with respect to the evaporator 6 of the indoor air flow path 10.
Reference numeral 22a denotes a control board chamber wall disposed between the compressor 4 and the control board 18 in the lower space 17, and reference numeral 22 denotes a control board chamber formed between the front surface of the front panel 1a and the control board wall 22a.

The evaporator 6 and the drain receiver 20 are located in the vicinity of the partition wall 7 in the frame 1 away from the front surface of the front panel 1a, and the drain water condensed by the evaporator 6 and dripped onto the drain receiver 20 is supplied from the water conduit 20a. Since the drain water is not treated on the front side of the frame 1 where the indoor blower 2 is arranged facing the condenser 5 on the outdoor side, condensation does not occur on the surface of the front panel 1a, and the control board 18 Even if it is arranged so as to face the front surface of the front panel 1a, there is no risk of drain water being applied to the control board 18.
For this reason, it is not necessary to provide a cover on the front side of the control board 18, and the control board chamber 22 can be formed between the control board chamber wall 22a and the front surface of the front panel 1a. The cost can be reduced by reducing the number of parts. Further, when the front panel 1a is removed, the control board 18 attached to the control board chamber 22 can be exposed to the front surface of the frame body 1, and disassembly / assembly work can be facilitated and maintenance can be improved. It became.

  Reference numeral 19 denotes a gap formed between the bottom surface of the fan case 15 and the top surface of the partition plate 16 by disposing the fan case 15 at a higher position than the partition plate 16, and the fan case 15 and the partition plate 16 are in contact with each other. It has a configuration that does not. Since air cooled through the evaporator 6 flows through the fan case 15, the surface of the fan case 15 is cooled to a low temperature, and the room air before passing through the evaporator 6 flowing through the indoor air flow path 10. Touching may cause condensation. On the other hand, since the gap 19 is formed between the partition plate 16 and the fan case 15, the cool air in the fan case 15 is not directly transmitted to the partition plate 16. For this reason, the surface of the partition plate 16 located on the upper surface of the control board chamber 22 does not cause dew condensation due to the cold air of the fan case 15, and the control board 18 disposed in the control board chamber 22 can be protected from water. Is.
