Description

  The present invention relates to an air conditioner that harmonizes indoor air.

  Patent Documents 1 and 2 disclose conventional air conditioners that take in indoor air to harmonize and send out conditioned air from a blowout port. The air conditioner disclosed in Patent Document 1 is provided with infrared sensors in a plurality of indoor areas, and the temperature of each area is detected by the infrared sensor. And the direction of the blowing airflow is changed based on the detected temperature to eliminate the temperature difference between the regions. Moreover, the air conditioner disclosed by patent document 2 can make indoor temperature uniform by sending conditioned air upward from a blower outlet.

  On the other hand, Patent Literature 3 discloses an air conditioner that intensively air-conditions two locations apart from each other in a room. In this air conditioner, for example, conditioned air is sent to the left from the upper part of the outlet, and conditioned air is sent to the right from the lower part. Moreover, it has the 1st, 2nd heat exchanger arrange | positioned in series, and the 1st, 2nd path | route which connects a 1st, 2nd heat exchanger is branched and provided. An opening / closing valve is provided in the first path, and an expansion valve and a capillary tube are provided in the second path.

When the on-off valve is opened and the expansion valve is closed, the first and second heat exchangers have the same cooling capacity. When the on-off valve is closed and the expansion valve is opened, the refrigerant flowing through the refrigeration cycle flows into the second heat exchanger via the capillary tube, so that the cooling capacity of the second heat exchanger is higher than that of the first heat exchanger. . Thereby, the temperature sent from the upper part of the blower outlet through which a large amount of air passing through the first heat exchanger circulates is slightly higher in temperature than the air sent from the lower part of the blower outlet. For this reason, the space of the upper left part of an air conditioner can be made into high temperature, and the space of the lower right part can be made into low temperature.

  According to the air conditioner disclosed in Patent Documents 1 and 2, the temperature in the room is substantially uniform. For this reason, when there are a plurality of users in the room, there is a problem that the comfort cannot be satisfied for each user if the temperature at which each user feels comfortable is different. Moreover, even if the indoor temperature distribution is in a non-uniform state as described in the conventional example of Patent Document 2, it cannot be matched with the temperature at which each user feels comfortable.

  On the other hand, according to the air conditioner disclosed in Patent Document 3, the two spaces can be set to different temperatures. However, since the indoor unit of the air conditioner is installed at various positions in the room, it can be set according to the installation position. The direction of the wind is changed by the user operation. For this reason, there is a problem in that the convenience of the air conditioner is inferior, requiring complicated operations.

<< First Embodiment >>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an indoor unit 1 of an air conditioner according to the first embodiment. The indoor unit 1 of the air conditioner has a main body held by a cabinet 2, and a front panel 3 provided with suction ports 4 on the upper surface side and the front surface side is detachably attached to the cabinet 2. The cabinet 2 is provided with a claw portion (not shown) on the rear side surface, and is supported by engaging the claw portion with a mounting plate (not shown) attached to the indoor side wall W1 (see FIG. 2).

  A blower outlet 5 for sending out air is provided at the front lower portion of the front panel 3. The blower outlet 5 is formed in the rectangle extended in the horizontal direction. The air outlet 5 is closed by four lateral louvers 111a, 111b, 111c, and 111d. The lateral louver 111a (first upper wind direction plate) is disposed at a position that closes the upper part of the left outlet 5a that forms the left half toward the outlet 5. The lateral louver 111b (second upper wind direction plate) is disposed at a position that closes the upper portion of the right outlet 5b that forms the right half of the outlet 5. The lateral louver 111c (first lower wind direction plate) is arranged at a position to close the lower portion of the left outlet 5a. The horizontal louver 111d (second lower wind direction plate) is disposed at a position that closes the lower portion of the right outlet 5b.

  The horizontal louvers 111a, 111b, 111c, and 111d have horizontal rotation shafts, and rotate independently by driving an airflow control motor 79 (see FIG. 28). Accordingly, the horizontal louvers 111a and 111c (first vertical wind direction changing unit) change the vertical wind direction of the airflow sent from the left outlet 5a. The horizontal louvers 111b and 111d (second up-and-down air direction changing unit) vary the up-and-down air direction of the airflow sent from the right outlet 5b.

  FIG. 2 is a side sectional view of the indoor unit 1. Inside the indoor unit 1, a ventilation path 6 that communicates from the suction port 4 to the blowout port 5 is formed. A blower fan 7 that sends out air is disposed in the blower path 6. For example, a cross flow fan or the like can be used as the blower fan 7. The air passage 6 is inclined downward as it goes forward, and has a front guide portion 6a that guides the air sent out by the air blowing fan 7 downward in the front. Moreover, the upper wall of the ventilation path 6 is an inclined surface that is inclined upward as it goes forward from the end of the front guide portion 6a.

  The front guide portion 6a is provided with a plurality of vertical louvers 12a (see FIG. 3) and 12b. FIG. 3 shows a top view of the vertical louvers 12a and 12b. A plurality of vertical louvers 12a (first left and right wind direction changing portions) arranged on the left side are each supported by a central portion by a support shaft 12d substantially perpendicular to the bottom surface of the front guide portion 6a, and the rear portion is connected by a connecting member 12c. Yes. As a result, the plurality of vertical louvers 12a rotate in conjunction with each other and vary the airflow direction in the left-right direction of the airflow sent from the left outlet 5a.

  Similarly, the plurality of vertical louvers 12b (second left and right wind direction changing portions) arranged on the right side are each supported by a central portion by a support shaft 12f that is substantially perpendicular to the bottom surface of the front guide portion 6a, and the rear portion by a connecting member 12e. It is connected. As a result, the plurality of vertical louvers 12b rotate in conjunction with each other and vary the airflow direction in the left-right direction of the airflow sent from the right outlet 5b.

  In FIG. 2, an air filter 8 that collects and removes dust contained in the air sucked from the suction port 4 is provided at a position facing the front panel 3. An indoor heat exchanger 9 is disposed between the blower fan 7 and the air filter 8 in the blower path 6. The indoor heat exchanger 9 is connected to a compressor (not shown) provided in an outdoor unit arranged outdoors, and the refrigeration cycle is operated by driving the compressor.

  The indoor heat exchanger 9 is cooled to a temperature lower than the ambient temperature during the cooling operation by the operation of the refrigeration cycle. Further, during the heating operation, the indoor heat exchanger 9 is heated to a temperature higher than the ambient temperature. A temperature sensor 61 is provided between the indoor heat exchanger 9 and the air filter 8 to detect the temperature of air sucked from the suction port 4, and the air conditioner is driven on the side of the indoor unit 1. A control unit 60 (see FIG. 28) for controlling is provided. A drain pan 10 that collects condensation that has fallen from the indoor heat exchanger 9 during cooling or dehumidification is provided in the lower part before and after the indoor heat exchanger 9.

  FIG. 4 is an external view showing a remote controller 31 for controlling the operation of the air conditioner of the present embodiment. The remote controller 31 has an operation unit 31a, a display unit 31b, and a transmission unit 31c. The operation unit 31a has a plurality of operation keys, and inputs an operation state of the air conditioner.

  The operation key of the operation unit 31a can be switched to an indoor cooling operation, a dehumidifying operation, or a heating operation. When the lower cover 31d is opened, another operation key is exposed, and the set temperature, wind direction, and wind speed can be set. In addition, the first and second regions obtained by dividing the room into left and right, front and rear, and top and bottom can be set separately. In addition, the installation position of the indoor unit 1 can be switched and input to the central portion excluding the left end, the right end, and both ends toward the wall. Thereby, the remote controller 31 constitutes an arrangement input means for inputting the arrangement of the indoor unit 1.

  The display unit 31b includes a liquid crystal display panel or the like, and displays the operating condition, time, set temperature, and the like of the air conditioner. Further, the schematic shape of the room R in which the indoor unit 1 is installed and the installation position of the indoor unit 1 are schematically displayed in a perspective view. And the preset temperature of the 1st, 2nd area | region divided | segmented right and left toward the indoor unit 1 can be set separately. In addition, the transmission unit 31 c transmits an operation signal from the operation unit 31 a to the indoor unit 1.

  Further, the user can set the wind speed to “light wind”, “weak wind”, “strong wind”, “automatic”, or the like. Thereby, it can be manually changed to a light breeze (about 4 m / s for a 6 tatami type air conditioner), a weak breeze (about 6 m / s), a strong breeze (about 8 m / s). In addition, when “automatic” is set, it can be switched to a light breeze, a light breeze, a strong breeze, etc. according to the driving situation.

  In the air conditioner having the above configuration, when a compressor (not shown) is driven, refrigerant from the outdoor unit (not shown) flows to the indoor heat exchanger 9 to operate the refrigeration cycle. Indoor air is sucked into the indoor unit 1 from the suction port 4 by driving the blower fan 7, and dust contained in the air is removed by the air filter 8.

  During the cooling operation, the air taken into the indoor unit 1 is cooled by exchanging heat with the indoor heat exchanger 9 on the low temperature side. The conditioned air cooled by the indoor heat exchanger 9 is sent out into the room with its direction regulated in the left-right direction and the up-down direction by the vertical louvers 12a, 12b and the horizontal louvers 111a, 111b, 111c, 111d.

<First air flow control>
When the indoor unit 1 is provided at the center in the left-right direction of the wall surface, a diagram in which the indoor unit 1 is arranged at the center of the wall surface as shown in FIG. Then, when an instruction is given to make the temperature distribution in the room uniform, the first airflow control is performed. In the first airflow control, as shown in FIG. 5, the upper lateral louvers 111a and 111b are arranged at an angle of, for example, 20 ° with respect to the horizontal so that the front is upward. The lower lateral louvers 111c and 111d are disposed at an angle of, for example, 5 ° or less with respect to the horizontal between the diagonally lower side where the front is slightly lower and substantially horizontal. Further, the vertical louvers 12a and 12b are arranged facing the front as shown in FIG. The vertical louvers 12a and 12b may be inclined in a range up to about 5 ° with the front facing outward. Then, the wind speed is set to “light wind”, and conditioned air is sent out from the outlet 5.

  The air that flows through the blowing path 6 and is delivered from the upper part of the outlet 5 is guided obliquely upward along the horizontal louvers 111a and 111b. The air that flows through the blowing path 6 and is sent out from the lower part of the outlet 5 is guided slightly downward or substantially horizontally along the horizontal louvers 111c and 111d. At this time, the air that swirls clockwise in the drawing by the blower fan 7 in the drawing and circulates increases the air volume at the upper part of the blower path 6 on the inner peripheral side. For this reason, the air sent out from the lower part of the blower outlet 5 follows the air sent out from the upper part. As a result, the conditioned air is sent obliquely upward from the outlet 5 as indicated by an arrow B1.

  Although the lower lateral louvers 111c and 111d may be arranged so as to be higher as they go forward, the air may be guided upward, but the conditioned air flowing along the lower surfaces of the lateral louvers 111c and 111d decreases. For this reason, a temperature difference may arise between the upper surface and the lower surface of the horizontal louvers 111c and 111d, which may cause condensation. Therefore, it is more desirable to arrange the horizontal louvers 111c and 111d between obliquely below and substantially horizontal.

  The air sent obliquely upward from the air outlet 5 flows along the ceiling wall S due to the Coanda effect, and reaches the side wall W2 (see FIG. 10) facing the indoor unit 1 while diffusing. And it descends | falls along the side wall W2 which opposes the indoor unit 1, distribute | circulates the floor surface F (refer FIG. 10), and conditioned air distribute | circulates the whole in the room R. FIG. As a result, the room is cooled to a uniform temperature.

<Second air flow control>
When the indoor unit 1 is provided at the left and right ends of the wall surface, a diagram in which the indoor unit 1 is arranged on one side of the wall surface by the input of the remote controller 31 is displayed (see FIG. 16). When an instruction is given to make the temperature distribution in the room uniform, the second airflow control is performed. When the indoor unit 1 is disposed at the end of a distance of, for example, 350 mm or less from the side wall orthogonal to the mounting surface, the air sent from the indoor unit 1 toward the front flows along the side wall due to the Coanda effect. For this reason, the air flow control different from the first air flow control is performed because the side close to the side wall is likely to be low temperature.

  In the second airflow control, the horizontal louvers 111a to 111d are arranged in the same manner as in the first airflow control. That is, as shown in FIG. 5 described above, the upper horizontal louvers 111a and 111b are arranged at an angle of, for example, 20 ° with respect to the horizontal so that the front is upward. The lower lateral louvers 111c and 111d are disposed at an angle of, for example, 5 ° or less with respect to the horizontal between the diagonally lower side where the front is slightly lower and substantially horizontal.

  The vertical louvers 12a and 12b are arranged toward the center of the room with respect to the front. That is, the vertical louvers 12a and 12b are inclined in the range of 15 ° to 30 ° toward the center of the opposite wall surface. When the indoor unit 1 is provided at the end of the shorter side wall W1 with the room R in FIG. 10 between 6 tatami mats, the direction from the indoor unit 1 toward the center of the opposite side wall W2 is relative to the vertical plane perpendicular to the side wall W1. Tilt about 20 °. For this reason, the inclination angle of the vertical louvers 12a and 12b may be set in a range of 15 ° to 30 ° in order to uniformly bring the room to a desired temperature even in a narrower room or a wider room. In addition, you may enable it for a user to set the inclination-angle of the vertical louvers 12a and 12b.

  Then, the wind speed is set to “light wind”, and conditioned air is sent out from the outlet 5. Thereby, the air sent out diagonally upward from the blower outlet 5 distribute | circulates along the ceiling wall S by the Coanda effect, and reaches | attains the side wall W2 (refer FIG. 10) facing the indoor unit 1 while diffusing. And it falls along the side wall W2, distribute | circulates the floor surface F (refer FIG. 10), and conditioned air distribute | circulates the whole inside of the room R. FIG. As a result, the room is cooled to a uniform temperature.

<Third airflow control>
Next, in the case where the first and second regions E1 and E2 (see FIG. 10) obtained by dividing the room left and right toward the indoor unit 1 are set to different temperatures by the operation unit 31a, depending on the arrangement of the indoor unit 1 The first to third air blowing modes can be selected. The first air blowing mode is selected when the indoor unit 1 is arranged at the center of the wall surface. The second ventilation mode is selected when the indoor unit 1 is disposed at the end of the wall surface and the side close to the indoor unit 1 is cooled. The third ventilation mode is selected when the indoor unit 1 is arranged at the end of the wall surface and the side far from the indoor unit 1 is cooled.

  Whether the arrangement of the indoor unit 1 is determined as the center part of the wall surface and the first ventilation mode is selected, or whether the arrangement of the indoor unit 1 is determined as the end part of the wall surface and the second and third ventilation modes are selected. Depends on the size of the room and the shape of whether the room is portrait or landscape. When the conditioned air is sent from the indoor unit 1 to the front, the second and third air blowing modes are selected when the conditioned air is disposed at a position where it does not diffuse left and right along the side wall orthogonal to the mounting surface. As an example, when the 6 tatami type indoor unit 1 is attached to the short side wall between the 6 tatami mats, the second and third air blowing modes are arranged when placed at a distance of, for example, 350 mm or less from the side wall orthogonal to the attachment surface. Is selected.

  When the first air blowing mode is selected by operating the remote controller 31, the third air flow control is performed. In the display unit 31b of the remote controller 31 shown in FIG. 4 described above, the first air blowing mode is selected, and the setting of the first region E1 on the left side (see FIG. 10) is set toward the indoor unit 1 arranged in the center of the wall surface. This represents a state in which the temperature is set to 24 ° C. and the set temperature of the second region E2 on the right side (see FIG. 10) is set to 26 ° C. The first and second regions E1 and E2 are divided by a vertical plane passing through the center of the side wall W1 (see FIG. 10).

  When the cooling operation is started at the set temperature, the vertical louvers 12a and 12b are arranged as shown in FIG. That is, the right vertical louver 12b is arranged in a direction toward the front. The left vertical louver 12a is arranged, for example, inclined at 40 ° to the left as it goes forward. For example, the right vertical louver 12b may be inclined slightly to the right by, for example, 5 ° in a range where the inclination angle is smaller than that of the vertical louver 12a.

  The right lateral louvers 111b and 111d are arranged in the same manner as in FIG. That is, the upper lateral louver 111b is arranged at an angle of 20 ° with respect to the horizontal, for example, so that the front is upward. The lower lateral louver 111d is disposed at an angle of 5 ° or less with respect to the horizontal, for example, between the diagonally lower side where the front is slightly lower and substantially horizontal. The left lateral louvers 111a and 111c are arranged as shown in FIG. That is, the horizontal louvers 111a and 111c are arranged between an obliquely lower side and a substantially horizontal side, which is slightly lower as it moves forward. For example, the horizontal louver 111a is arranged horizontally, and the horizontal louver 111c is arranged so that the front is 10 ° below the horizontal. FIG. 8 is a perspective view of the indoor unit 1 showing this state.

  Then, similarly to the first airflow control, the wind speed is set to “slight wind”, the blower fan 7 is driven, and conditioned air is sent out from the blowout port 5 as shown in FIG. That is, the conditioned air is sent from the left outlet 5a toward the left substantially horizontal or slightly to the left as shown by the arrow A1. Further, the image is sent while being inclined leftward by an inclination angle α with respect to a vertical plane passing through the center of the side wall W1. From the right outlet 5b, conditioned air is sent obliquely upward on the front as shown by arrow B1.

  FIG. 10 shows a flow state of the air sent into the room. Air (B1) airflow (hereinafter referred to as “second airflow”) delivered from the right outlet 5b circulates along the ceiling wall S due to the Coanda effect while diffusing to the left and right, and gradually decreases the speed. And it falls along the wide range of the side wall W2 facing the indoor unit 1.

  An airflow (hereinafter referred to as “first airflow”) of air (A1) sent from the left outlet 5a flows along the left side wall W3 toward the indoor unit 1 and reaches the side wall W2. Then, the second airflow merges with the first airflow and circulates on the floor surface F.

  The inclination angle α (see FIG. 9) of the first airflow is preferably 20 ° or more. When the indoor unit 1 is provided in the center of the shorter side wall W1 with the room R in FIG. 10 between 6 tatami mats, the direction from the center of the indoor unit 1 to the corner where the side walls W2, W3 intersect is a vertical plane perpendicular to the side wall W1. Inclined about 20 °. Therefore, when the inclination angle α of the first airflow is set to 20 ° or more, the first airflow can be reliably made to follow the side wall W3. When the room R is between 8 tatami mats or when the indoor unit 1 is in front and horizontally long, the inclination angle α can be set to be larger than 20 ° along the side wall W3.

  Since the second air flow (B1) is sent out toward the front, the first region E1 on the left side of the room R and the second region E2 on the right side of the room R are cooled with the same cooling capacity by the second air flow (B1). On the other hand, since the first air flow (A1) is sent to the left, the first region E1 on the left side of the room R is cooled more than the second region E2 by the first air flow (A1). As a result, the average temperature of the first region E1 is lower than the average temperature of the second region E2.

  For example, when ½ each of conditioned air is sent out from the left outlet 5a and the right outlet 5b, the first and second regions are each ¼ of the conditioned air sent out from the outlet 5 by the second air flow. It is cooled with each cooling capacity. In addition, the first region is cooled by the first airflow with a cooling capacity of about ½ of the conditioned air sent from the blowout port 5. Thereby, the cooling capacity of 3/4 of the conditioned air sent from the blower outlet 5 is supplied to the first region.

  Further, as shown in FIG. 6 described above, the vertical louver 12a is inclined, so that the first air flow (A1) delivered from the left outlet 5a has an air volume due to an increase in pressure loss and a decrease in cross-sectional area due to the vertical louver 12a. Decrease. For this reason, the temperature of the first air stream (A1) is lower than the second air stream by heat exchange with the indoor heat exchanger 9. Therefore, the average temperature of the first region E1 can be further lowered than the average temperature of the second region E2.

  FIGS. 11-15 has shown the temperature distribution in the room R at the time of 2nd airflow control. The size of the room R is 6 tatami mats (height 2400 mm, width 3600 mm, depth 2700 mm). 11 and 12 show the measurement results of the cross-sections of the alternate long and short dash lines D1 and D2 shown in FIG. 13 and 14 show the measurement results of the cross-sections of the two-dot chain lines D3 and D4 shown in FIG. FIG. 15 shows the measurement result of the cross section of the broken line D5 shown in FIG.

  The D1 cross section is a position parallel to the side wall W3 and 675 mm from the side wall W3, and is a cross section at a position on the left side of the indoor unit 1 in the room R. The cross section D2 is a position parallel to the side wall W4 facing the side wall W3 and 675 mm from the side wall W4, and is a cross section at a position on the right side ¼ toward the indoor unit 1 in the room R. The cross section D3 is a position parallel to the side wall W1 and 1200 mm from the side wall W1, and is a cross section at a position 1/3 ahead of the indoor unit 1 in the room R. The D4 cross section is a cross section at a position parallel to the side wall W2 facing the side wall W1 and 1200 mm from the side wall W2, and at a position 1/3 rearward toward the indoor unit 1 in the room R. The D5 cross section is a cross section at a position parallel to the floor surface F and 600 mm from the floor surface F, and 1/4 from the bottom of the room R.

  According to these figures, the temperature of the first region E1 on the left side of the room R toward the indoor unit 1 is controlled to about 24 ° C. In addition, the temperature of the second region E2 on the right side of the indoor unit 1 is controlled to about 26 ° C. Therefore, the temperature difference between the first and second regions E1 and E2 can be set at about 2 ° C.

  At this time, air flows from the side wall W2 toward the side wall W1 in the lower central partial living space of the room R. For this reason, the air sent out from the blower outlet 5 is decelerated, the wind speed of 1st area | region E1 is 0.1 m / s or less, and the wind speed of 2nd area | region E2 is about 0.2 m / s. Therefore, cold air does not directly pour into the living space, and an extremely low-speed airflow flows, so that it is possible to prevent the health of the user from being impaired. If the wind speed is 0.5 m / s or less, the user feels almost no wind. For this reason, the rotation speed of the ventilation fan 7 is determined so that the wind speed of living space may be 0.5 m / s or less.

The first air stream (A1) has an air volume of 2.5 m ³ / min, the wind speed is 3 m / s, the blowing temperature is 10 ° C., the air stream of the second air stream (B1) is 5 m ³ / min, and the wind speed is 6 m / s, the blowing temperature is 15 ° C. As described above, the air volume and the wind speed are different due to pressure loss or the like, and the blowing temperature of the first air stream (A1) is low. Moreover, since the wind speed of 1st airflow is low, the quantity of the conditioned air which circulates from the 1st area | region E1 to the 2nd area | region E2 reduces, and the quantity stagnated in the 1st area | region E1 increases. Thereby, the temperature of the first region E1 can be made lower than that of the second region E2 more easily.

  The heat exchanger 9 may be divided into left and right parts so that the respective heat exchangers have different temperatures, and a temperature difference between the first and second airflows may be provided. Further, the blower fan 7 may be divided into left and right, and the respective blower fans may have different rotation speeds, and the first and second airflows may have different wind speeds and air volumes. Thus, the temperature of the first and second regions can be adjusted more finely.

  Moreover, since conditioned air is sent in different directions from the left and right left outlets 5a and 5b of the outlet 5, comfort can be improved. That is, when conditioned air is sent in different directions from above and below the air outlet 5, a temperature difference is generated between the upper and lower surfaces of the horizontal louver. As a result, condensation may occur on the horizontal louver, and water may be sprayed on the user or the user may be uncomfortable by flooding the room. On the other hand, if conditioned air is sent out from the left outlet 5a and the right outlet 5b in different directions, occurrence of a temperature difference between the upper and lower surfaces of the lateral louvers 111a to 111d is suppressed, and condensation is prevented and comfort is improved.

  When a larger temperature difference is provided in the first and second regions E1 and E2, the right vertical louver 12b is disposed so as to be inclined forward (inward) on the left side. By arranging the vertical louver 12b with the front inclined inward (left side), the second air flow (B1) (see FIG. 10) sent out from the right outlet 5b is the second region E2 on the right side of the room R. More than the first area E1 on the left side. For this reason, more cooling capacity is provided in the first region E1 on the left side than the second region E2 on the right side of the room R.

  And since the whole air quantity sent out from the blower outlet 5 reduces, the rotation speed of the ventilation fan 7 is increased and an air volume is increased. As a result, the temperature difference between the first and second regions E1 and E2 increases. Further, the absolute room temperature of the first and second regions E1 and E2 is adjusted by changing the rotational speed of the compressor (not shown).

  In addition, when the indoor unit 1 is arrange | positioned at the edge part of the right side of a room | chamber interior, what is necessary is just to arrange | position the whole vertical louvers 12a and 12b and the horizontal louvers 111a-111d symmetrically.

<Fourth air flow control>
Next, when the second air blowing mode is selected by operating the remote controller 31, fourth airflow control is performed. FIG. 16 shows a display state of the remote controller 31 that has selected the second air blowing mode. That is, the indoor unit 1 is arranged on the left side toward the wall surface to which the indoor unit 1 is attached, the set temperature of the left first region E1 (see FIG. 10) is set to 24 ° C., and the right second region E2 (see FIG. 10) is set to 26 ° C.

  When the cooling operation is started at this set temperature, the vertical louver 12a is disposed so as to be inclined in the range of 5 ° to 10 ° with the front facing slightly outward. The vertical louver 12b is disposed so as to be inclined with an inclination angle in the range of 15 ° to 30 ° with the front facing outward. Further, the horizontal louvers 111a, 111b, 111c, and 111d are arranged in the same manner as in the third airflow control. That is, the upper lateral louver 111b is arranged at an angle of 20 ° with respect to the horizontal, for example, so that the front is upward.

  The lower lateral louver 111d is disposed at an angle of 5 ° or less with respect to the horizontal, for example, between the diagonally lower side where the front is slightly lower and substantially horizontal. The left lateral louvers 111a and 111c are arranged as shown in FIG. That is, the horizontal louvers 111a and 111c are arranged between an obliquely lower side and a substantially horizontal side, which is slightly lower as it moves forward. For example, the horizontal louver 111a is arranged horizontally, and the horizontal louver 111c is arranged so that the front is 10 ° below the horizontal.

  Then, as in the first airflow control, the wind speed is set to “breeze”, the blower fan 7 is driven, and conditioned air is sent out from the outlet 5 as shown in FIG. That is, the conditioned air is sent from the left outlet 5a toward the left substantially horizontal or slightly leftward as shown by the arrow A2. From the right outlet 5b, conditioned air is sent obliquely upward to the right as indicated by an arrow B2.

  The second air flow (B2) delivered from the right outlet 5b circulates along the ceiling wall S by the Coanda effect while diffusing left and right, and gradually decreases the speed. And it falls along the wide range of the side wall W2 facing the indoor unit 1. The first air flow (A2) sent out from the left outlet 5a flows along the left side wall W3 toward the indoor unit 1 and reaches the side wall W2. Then, the second airflow merges with the first airflow and circulates on the floor surface F.

  Since the second air flow (B2) is sent out to descend along the opposite side wall W2, the first region E1 on the left side of the room R and the second region E2 on the right side of the room R are equivalent by the second air flow (B2). Cooled with cooling capacity. On the other hand, since the first air flow (A2) is sent to the left, the first region E1 on the left side of the room R is cooled more than the second region E2 by the first air flow (A2). As a result, the average temperature of the first region E1 is lower than the average temperature of the second region E2.

  FIG. 18 shows the temperature distribution in the room R during the fourth airflow control. The size of the room R is 6 tatami mats (height 2400 mm, width 3600 mm, depth 2700 mm). This figure shows the measurement result of the cross section of the broken line D5 shown in FIG. The D5 cross section is a cross section at a position parallel to the floor surface F and 600 mm from the floor surface F, and 1/4 from the bottom of the room R.

  According to the figure, the temperature of the first region E1 on the left side of the room R toward the indoor unit 1 is controlled to about 24 ° C. In addition, the temperature of the second region E2 on the right side of the indoor unit 1 is controlled to about 26 ° C. Therefore, the temperature difference between the first and second regions E1 and E2 can be set at about 2 ° C.

  At this time, air flows from the side wall W2 toward the side wall W1 in the living space in the lower central portion of the room R. For this reason, the air sent out from the blower outlet 5 is decelerated, the wind speed of 1st area | region E1 is 0.2 m / s, and the wind speed of 2nd area | region E2 is 0.1 m / s or less. Therefore, cold air does not directly pour into the living space, and an extremely low-speed airflow flows, so that it is possible to prevent the health of the user from being impaired.

  In addition, when the indoor unit 1 is arrange | positioned at the edge part of the right side of a room | chamber interior, what is necessary is just to arrange | position the whole vertical louvers 12a and 12b and the horizontal louvers 111a-111d symmetrically.

<Fifth air flow control>
Next, when the third ventilation mode is selected by operating the remote controller 31, fifth airflow control is performed. FIG. 19 shows a display state of the remote controller 31 that has selected the second air blowing mode. That is, the indoor unit 1 is arranged at the left end toward the wall surface to which the indoor unit 1 is attached, the set temperature of the left first region E1 (see FIG. 10) is set to 26 ° C., and the right second region This represents a state in which the set temperature of E2 (see FIG. 10) is set to 24 ° C.

  When the cooling operation is started at this set temperature, the vertical louver 12a is arranged with an inclination angle in the range of 5 ° to 20 ° with the front facing slightly toward the center of the room. The vertical louver 12b is disposed so as to be inclined in the range of 30 ° to 50 ° with the front facing outward. The horizontal louver 111a on the upper left side is arranged at an angle of, for example, 20 ° with respect to the horizontal so that the front is upward, like the horizontal louver 111b shown in FIG. The lower horizontal louver 111c is disposed at an angle of 5 ° or less with respect to the horizontal, for example, between the diagonally lower side where the front is slightly lower and substantially horizontal.

  The right lateral louvers 111b and 111d are arranged in the same manner as the lateral louvers 111a and 111c shown in FIG. In other words, the horizontal louvers 111b and 111d are arranged between an obliquely lower side and a substantially horizontal side, which is slightly lower as it moves forward. For example, the horizontal louver 111b is arranged horizontally, and the horizontal louver 111d is arranged so that the front is 10 ° below the horizontal.

  And a wind speed is set to "strong wind", the ventilation fan 7 is driven, and conditioned air is sent out from the blower outlet 5 as shown in FIG. In other words, the conditioned air is sent from the left outlet 5a toward the slightly upper right as shown by the arrow A3. From the right outlet 5b, conditioned air is sent out substantially horizontally on the right side or slightly downward on the right side as indicated by an arrow B3.

  The first air flow (A3) delivered from the left outlet 5a circulates along the ceiling wall S due to the Coanda effect while diffusing left and right, and gradually decreases the speed. And it falls along the wide range of the side wall W2 facing the indoor unit 1. The second air flow (B3) sent out from the right outlet 5b flows along the right side wall W4 toward the indoor unit 1 and reaches the side wall W2. Then, the second airflow merges with the first airflow and circulates on the floor surface F.

  Since the first air flow (A3) is sent out so as to descend along the opposite side wall W2, the first region E1 on the left side of the room R and the second region E2 on the right side of the room R are equivalent by the first air flow (A3). Cooled with cooling capacity. On the other hand, since the third air flow (B3) is sent out toward the right side wall W4, the second region E2 on the right side of the room R is cooled more than the first region E1 by the second air flow (B3). As a result, the average temperature of the first region E1 is higher than the average temperature of the second region E2.

  FIG. 18 shows the temperature distribution in the room R during the fourth airflow control. The size of the room R is 6 tatami mats (height 2400 mm, width 3600 mm, depth 2700 mm). This figure shows the measurement result of the cross section of the broken line D5 shown in FIG. The D5 cross section is a cross section at a position parallel to the floor surface F and 600 mm from the floor surface F, and at a position ¼ from the bottom of the room R.

  According to the figure, the temperature of the first region E1 on the left side of the room R toward the indoor unit 1 is controlled to about 26 ° C. In addition, the temperature of the second region E2 on the right side of the indoor unit 1 is controlled to about 24 ° C. Therefore, the temperature difference between the first and second regions E1 and E2 can be set at about 2 ° C.

  At this time, air flows from the side wall W2 toward the side wall W1 in the living space in the lower central portion of the room R. For this reason, the air sent out from the blower outlet 5 is decelerated, the wind speed of 1st area | region E1 is 0.1 m / s or less, and the wind speed of 2nd area | region E2 is about 0.2 m / s. Therefore, cold air does not directly pour into the living space, and an extremely low-speed airflow flows, so that it is possible to prevent the health of the user from being impaired.

  In addition, when the indoor unit 1 is arrange | positioned at the edge part of the right side of a room | chamber interior, what is necessary is just to arrange | position the whole vertical louvers 12a and 12b and the horizontal louvers 111a-111d symmetrically.

  According to this embodiment, regardless of the arrangement of the indoor unit 1, the first area E1 and the second area E2 obtained by dividing the room into left and right can be set to substantially the same temperature. Further, by selecting the first to third air blowing modes, the first and second regions E1 and E2 can be easily temperature-controlled to different temperatures. Therefore, even when the temperature at which a plurality of users feel comfortable differs, comfort can be easily satisfied for a plurality of users in the room regardless of the arrangement of the indoor unit 1.

Further, in the first to fifth airflow control, the airflow flows from the wall surface W2 facing the indoor unit 1 toward the wall surface W1 where the indoor unit 1 is installed in the lower part of the first and second regions E1 and E2. For this reason, the wind speed of the residential area in the lower part of the room can be easily reduced to 0.5 m / s or less. Accordingly, it is possible to prevent the user from being exposed directly to the cold air and to prevent the user from being damaged.
<< Second Embodiment >>
Next, FIG. 22 is a perspective view showing the indoor unit 1 of the air conditioner of the second embodiment. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment shown in FIGS. In the present embodiment, lateral louvers 112a, 112b, and 112c are provided in place of the lateral louvers 111a, 111b, 111c, and 111d of the first embodiment. Other parts are the same as those in the first embodiment.

  The lateral louver 112a (first upper wind direction plate) is arranged at a position to close the upper part of the left outlet 5a. The lateral louver 112b (second upper wind direction plate) is arranged at a position to close the upper part of the right outlet 5b. The lateral louver 112c (lower wind direction plate) is disposed at a position where the lower portion of the blowout port 5 is closed. The horizontal louvers 112a, 112b, and 112c have horizontal rotation shafts and rotate independently by driving the airflow control motor 79 (see FIG. 28). Therefore, the left part of the horizontal louver 112c and the horizontal louver 112a change the vertical direction of the airflow sent from the left outlet 5a. The right part of the horizontal louver 112c and the horizontal louver 112b change the vertical direction of the airflow sent from the right outlet 5b.

  In the case of performing the first airflow control, the vertical louvers 12a and 12b are arranged as shown in FIG. The horizontal louvers 112a, 112b, and 112c are rotated and arranged in the same manner as the horizontal louvers 111a, 111b, and 111c shown in FIG. Thereby, the conditioned air can be sent out during the cooling operation similarly to the first embodiment, and the indoor temperature during the cooling operation can be made uniform.

  When performing 2nd airflow control, the horizontal louvers 112a-112c are arrange | positioned similarly to 1st airflow control. The vertical louvers 12a and 12b are arranged toward the center of the room with respect to the front. Thereby, the conditioned air can be sent out during the cooling operation similarly to the first embodiment, and the indoor temperature during the cooling operation can be made uniform.

  When the third airflow control is performed by selecting the first air blowing mode, the vertical louvers 12a and 12b are arranged as shown in FIG. The lateral louvers 112b and 112c are arranged in the same manner as in the first airflow control. The horizontal louver 112a is rotated and arranged in the same manner as the horizontal louver 111a shown in FIG. FIG. 22 shows the state of the indoor unit 1 at this time.

  The delivery direction in the vertical direction of the left outlet 5a is regulated by the left side (first vertical wind direction variable portion) of the horizontal louver 112a and the horizontal louver 112c. The delivery direction in the vertical direction of the right outlet 5b is restricted by the right side (second vertical wind direction variable portion) of the horizontal louver 112b and the horizontal louver 112c. Thereby, the conditioned air is sent out by the indoor unit 1 arranged at the center of the wall surface during the cooling operation, as in the first embodiment. As a result, the first and second regions E1 and E2 (see FIG. 10) obtained by dividing the room into left and right are controlled to different temperatures.

  As described above, the amount of air flowing through the upper portion of the air blowing path 6 is larger than the amount of air flowing through the lower portion. For this reason, even if the lower horizontal louver 112c has the same angle on the left and right, the air flow can be sent in different directions in the vertical direction at the left outlet 5a and the right outlet 5b as in the first embodiment.

  When performing the fourth airflow control by selecting the second air blowing mode, the lateral louvers 112a, 112b, and 112c are arranged in the same manner as the third airflow control. The vertical louver 12b is disposed so as to be inclined in the range of 5 ° to 10 ° with the inclination angle facing forward slightly outward. The vertical louver 12b is disposed so as to be inclined with an inclination angle in the range of 15 ° to 30 ° with the front facing outward.

  Thereby, the conditioned air is sent out by the indoor unit 1 arranged at the left end of the wall surface during the cooling operation, as in the first embodiment. As a result, the first area E1 obtained by dividing the room into the left and right can be maintained at a lower temperature than the second area E2 (see FIG. 17).

  When the fifth airflow control is performed by selecting the third air blowing mode, the lateral louver 112a is arranged so that the front side is upward, like the lateral louver 111b shown in FIG. The horizontal louvers 112b and 112c are arranged in the same manner as the horizontal louvers 111a and 111d shown in FIG.

  The vertical louver 12a is disposed so as to be inclined in the range of 5 ° to 20 ° with the front facing slightly toward the center of the room. The vertical louver 12b is disposed so as to be inclined in the range of 30 ° to 50 ° with the front facing outward.

  Thereby, the conditioned air is sent out by the indoor unit 1 arranged at the left end of the wall surface during the cooling operation, as in the first embodiment. As a result, the first area E1 obtained by dividing the room into the left and right can be maintained at a higher temperature than the second area E2 (see FIG. 20).

<< Third Embodiment >>
Next, FIG. 23 is a perspective view showing the indoor unit 1 of the air conditioner of the third embodiment. The same parts as those in the first embodiment shown in FIGS. In this embodiment, horizontal louvers 113a and 113b are provided instead of the horizontal louvers 111a, 111b, 111c, and 111d of the first embodiment. Other parts are the same as those in the first embodiment.

  The lateral louver 113a (upper wind direction plate) is arranged at a position that closes the upper part of the air outlet 5. The lateral louver 113b (lower wind direction plate) is disposed at a position where the lower portion of the outlet 5 is closed. The horizontal louvers 113a and 113b have horizontal rotation shafts, and rotate independently by driving the airflow control motor 79 (see FIG. 28). Further, the lateral louvers 113a and 113b are made of a soft flexible material, and a rotational torque in opposite directions can be applied to the rotating shafts at both ends by an airflow control motor 79 (see FIG. 28). Thereby, the horizontal louvers 113a and 113b can be twisted as shown in FIG.

  Therefore, the left part of the horizontal louvers 113a and 113b varies the vertical direction of the airflow sent from the left outlet 5a. The right part of the horizontal louvers 113a and 113b varies the vertical direction of the airflow sent from the right outlet 5b.

  When the first airflow control is performed, the vertical louvers 12a and 12b (first and second left and right wind direction changing units) are arranged as shown in FIG. The horizontal louvers 113a and 113b are rotated and arranged in the same manner as the horizontal louvers 111a and 111c shown in FIG. Thereby, the conditioned air can be sent out during the cooling operation similarly to the first embodiment, and the indoor temperature during the cooling operation can be made uniform.

  When performing the second airflow control, the lateral louvers 113a and 113b are arranged in the same manner as the first airflow control. The vertical louvers 12a and 12b are arranged toward the center of the room with respect to the front. Thereby, the conditioned air can be sent out during the cooling operation similarly to the first embodiment, and the indoor temperature during the cooling operation can be made uniform.

  When the third airflow control is performed by selecting the first air blowing mode, the vertical louvers 12a and 12b are arranged as shown in FIG. The right part (second up-and-down wind direction variable part) of the horizontal louvers 113a and 113b is arranged in the same manner as the first airflow control. The left portions (the first up / down air direction variable portion) of the horizontal louvers 113a and 113b are twisted and arranged in the same manner as the horizontal louvers 111a and 111c shown in FIG. FIG. 25 is a perspective view showing the indoor unit 1 at this time. Accordingly, during the cooling operation, the conditioned air is sent out in the same manner as in the first embodiment, and the first and second regions E1 and E2 (see FIG. 10) divided into the left and right rooms are controlled to different temperatures.

  When the fourth airflow control is performed by selecting the second air blowing mode, the horizontal louvers 113a and 113b are arranged in the same manner as the third airflow control. The vertical louver 12b is disposed so as to be inclined in the range of 5 ° to 10 ° with the inclination angle facing forward slightly outward. The vertical louver 12b is disposed so as to be inclined with an inclination angle in the range of 15 ° to 30 ° with the front facing outward.

  Thereby, the conditioned air is sent out by the indoor unit 1 arranged at the left end of the wall surface during the cooling operation, as in the first embodiment. As a result, the first area E1 obtained by dividing the room into the left and right can be maintained at a lower temperature than the second area E2 (see FIG. 17).

  When the fifth airflow control is performed by selecting the third air blowing mode, the left portions of the horizontal louvers 113a and 113b are arranged in the same manner as the first airflow control. The right portions (first up-and-down wind direction variable portions) of the horizontal louvers 113a and 113b are twisted and arranged in the same manner as the horizontal louvers 111a and 111c shown in FIG.

  The vertical louver 12a is disposed so as to be inclined in the range of 5 ° to 20 ° with the front facing slightly toward the center of the room. The vertical louver 12b is disposed so as to be inclined in the range of 30 ° to 50 ° with the front facing outward.

  Thereby, the conditioned air is sent out by the indoor unit 1 arranged at the left end of the wall surface during the cooling operation, as in the first embodiment. As a result, the first area E1 obtained by dividing the room into the left and right can be maintained at a higher temperature than the second area E2 (see FIG. 20).

  In the first to third embodiments, the schematic shape of the room R and the schematic installation position of the indoor unit 1 are displayed in a schematic perspective view on the display unit 31a of the remote controller 31 shown in FIG. The display screen of the display unit 31a is not limited to this, and other screens may be displayed. For example, as shown in FIG. 26, a plan view 31e representing the installation position of the indoor unit 1 is provided, and the set temperatures of the first and second regions E1 and E2 are arranged side by side as “24 ° C., 26 ° C.”. May be. That is, it is only necessary that the user can easily understand which arrangement of the indoor unit 1 is selected. In addition, as shown in FIG. 27, by sliding a slide-type lid 31d, the temperature, air direction, air volume, etc. can be input in more detail.

  Each airflow control is performed when a command is issued from the remote controller 31 by a user's operation, but may be automatically switched and executed when the room temperature reaches a predetermined condition. Further, a microphone (not shown) connected via a voice recognition unit (not shown) may be provided in the indoor unit 1 and commanded to the control unit. That is, when speaking to the microphone, for example, “Left is cold”, the temperature of the first area divided into the left and right can be controlled to be lower than that of the second area from the state of uniform temperature distribution in the room.

  Moreover, you may connect an air conditioner and a communication terminal via networks, such as the internet. The communication terminal includes a personal computer, a telephone, a mobile phone, and the like, and is connected to the network by a wireless mobile communication network, a telephone line, satellite communication, a cable line, and the like.

<< Fourth Embodiment >>
Next, FIG. 28 is a block diagram showing a control unit of the air conditioner of the fourth embodiment. In the present embodiment, in addition to the air conditioner of the first embodiment shown in FIGS. 1 to 21 described above, a distance detector 78 that detects the distance from the indoor unit 1 to the wall surface orthogonal to the mounting surface of the indoor unit 1 is provided. I have. In addition, arrangement detection means for detecting the arrangement of the indoor unit 1 based on the detection result of the distance detection unit 78 is provided. Other parts are the same as those in the first embodiment.

  The control unit 60 includes a CPU 71 that performs various arithmetic processes, and an input circuit 72 that receives an input signal and an output circuit 73 that outputs a calculation result of the CPU 71 are connected to the CPU 71. Further, a memory 74 is provided for storing a calculation program of the CPU 71 and temporarily storing calculation results.

  An airflow control motor 79 is connected to the output circuit 73. The airflow control motor 79 drives the vertical louvers 12a and 12b and the horizontal louvers 111a to 111d to change the blowing direction of the conditioned air. A detection signal from the distance detector 78 is input to the input circuit 72. The distance detector 78 detects the distances to the side walls W3 and W4 (see FIG. 10) orthogonal to the side wall W1 where the indoor unit 1 is installed.

  The distance detection unit 78 measures light by emitting light or sound and capturing light or sound reflected by the side walls W3 and W4. The distance detection unit 78 may have another configuration. For example, the distance may be measured by extending a rod-shaped member from the indoor unit 1 toward the side walls W3 and W4. Alternatively, the distance may be calculated by taking images of the side walls W3 and W4.

  FIG. 29 is a flowchart showing a detection operation of the arrangement of the indoor unit 1 of the air conditioner having the above-described configuration. In step # 11, the distance detector 78 detects the distance L3 between the indoor unit 1 and the left side wall W3 and the distance L4 between the right side wall W4. In step # 12, it is determined whether or not the distance L3 is larger than a predetermined distance L0.

  The distance L0 is set to, for example, 350 mm in order to determine whether or not the installation position of the indoor unit 1 is the end of the wall surface. The distance L0 has an optimum value inherently depending on the shape of the air outlet 5, the shape of the front surface portion of the air conditioner, the blowing direction, the shapes of the vertical louvers 12a and 12b, and the like. For this reason, it is determined at the design stage of the air conditioner and stored in the memory 74 of the control unit 60 in advance.

  If the distance L3 is greater than the distance L0, the process proceeds to step # 13, and it is determined whether the distance L4 is greater than the distance L0. When the distance L4 is larger than the distance L0, the process proceeds to step # 14, and the memory 74 stores that the indoor unit 1 is disposed at the center. Thereby, the first airflow control is performed when the indoor temperature is made uniform. Moreover, when providing a temperature difference in 1st, 2nd area | region E1, E2, 1st ventilation mode is selected by the control part, and 3rd airflow control is performed.

  If the distance L4 is less than or equal to the distance L0 in step # 13, the process proceeds to step # 15, and the memory 74 stores that the indoor unit 1 is disposed at the right end. Thereby, the second airflow control is performed when the indoor temperature is made uniform. When 2nd area | region E2 is set to low temperature rather than 1st area | region E1, 2nd ventilation mode is selected by the control part 60, and 4th airflow control is performed. When the second region E2 is set to a higher temperature than the first region E1, the third air blowing mode is selected by the control unit 60, and the fifth airflow control is performed.

  When the distance L3 is equal to or smaller than the distance L0 in step # 12, the process proceeds to step # 16, and it is determined whether or not the distance L4 is larger than the distance L0. If the distance L4 is greater than the distance L0, the process proceeds to step # 17, and the memory 74 stores that the indoor unit 1 is disposed at the left end. Thereby, the second airflow control is performed when the indoor temperature is made uniform. When the first region E1 is set at a lower temperature than the second region E2, the second air blowing mode is selected by the control unit 60, and the fourth airflow control is performed. When the first region E1 is set to a higher temperature than the second region E2, the third air blowing mode is selected by the control unit 60, and the fifth airflow control is performed.

  If the distance L4 is equal to or less than the distance L0 in step # 16, the room width is narrow and divided into left and right, making temperature control difficult. For this reason, the fact that the temperature management cannot be divided is stored in the memory 74. Thereby, the first airflow control is performed when the indoor temperature is made uniform. Further, the operation of the remote controller 31 is limited so that a temperature difference cannot be set in the first and second regions E1 and E2.

  The arrangement of the indoor unit 1 is detected by the above operation. Therefore, the arrangement detection means for detecting the arrangement of the indoor unit 1 is configured by the control unit 60 and the distance detection unit 78 having the operation program of the flowchart. Incidentally, the air conditioner operating condition can be changed by driving the airflow control motor 79 by a predetermined operation by the remote controller 31 regardless of the detection result of the arrangement detecting means.

  Further, the input circuit 72 or the output circuit 73 may be provided with several stages of changeover switches corresponding to the distance between the indoor unit 1 and the left side wall W3 and the right side wall W4. When the indoor unit 1 is installed, the installation worker or user operates the changeover switch according to the distance from the left side wall W3 and the right side wall W4. Thereby, the changeover switch may constitute an arrangement input unit that inputs the arrangement of the indoor unit 1, and the changeover switch may be provided so that the airflow control can be changed regardless of the detection result of the arrangement detection unit.

  Further, it is not necessary to perform the operation of the above flowchart every time the cooling operation is performed. For example, it may be performed at regular intervals, when a power outlet is inserted into the power plug, or when the indoor unit 1 is installed. Thereby, air conditioning can be started quickly.

  The blowing direction may be changed stepwise in accordance with the distances L3 and L4 between the indoor unit 1 and the left side wall W3 and the right side wall W4. In this case, since detailed operation conditions can be set according to the distance between the indoor unit 1, the left side wall W3, and the right side wall W4, a more comfortable living space can be obtained.

  According to this embodiment, since the arrangement | positioning detection means which detects arrangement | positioning of the indoor unit 1 is provided, it is not necessary for a user to input arrangement | positioning of the indoor unit 1, and the convenience of an air conditioner improves. In addition, although the arrangement | positioning detection means is provided in the air conditioner of 1st Embodiment, you may provide an arrangement | positioning detection means in the air conditioner of 2nd, 3rd embodiment.

  In the first to fourth embodiments, the arrangement of the vertical louvers 12a and 12b and the horizontal louvers 111a to 111d, 112a to 112c, 113a and 113b at the time of the first to fifth airflow control is the shape of the air outlet 5, the air conditioner There is an optimal orientation inherently depending on the shape of the front surface. For this reason, arrangement | positioning of each part is determined in the design stage of an air conditioner, and is previously memorize | stored in the memory 74 at the time of shipment.

  Although the air conditioner according to the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be implemented with appropriate modifications without departing from the spirit of the present invention.

  The present invention can be used for an air conditioner that harmonizes indoor air.
