Placed in. In addition, when the 1st connection part 31,32,33 is arrange | positioned in a rack fully closed position and the 2nd connection part 34,35 is arrange | positioned in a link fully closed position, as shown in FIG. The blade 30 takes a first posture that covers the air outlet 15.

  In addition, the second protrusion mechanisms 71a and 71b open the link connecting portions 34 and 35 from the second motors 73a and 73b by a fourth predetermined distance which is a distance larger than the third predetermined distance. It can be moved to a position (see FIG. 8). The link fully open position is a structure hitting position where the up / down airflow direction adjusting blade 30 contacts the moving members 43, 53, 63 when the second connecting portions 34, 35 are moved.

  Furthermore, the second protrusion mechanisms 71a and 71b can move the second connecting portions 34 and 35 to the link fully closed position, which is a position away from the second motors 73a and 73b by a fifth predetermined distance. (See FIGS. 9 and 10). Note that the link fully closed position is a structure hitting position at which the vertical airflow direction adjusting blade 30 contacts the indoor unit casing 12 or the link mechanisms 72a and 72b when the second connecting portions 34 and 35 are moved. For example, when the first connecting parts 31, 32, 33 are arranged at the first predetermined position and the second connecting parts 34, 35 are moved to the link fully closed position, as shown in FIG. The up-and-down air direction adjusting blade 30 and the indoor unit casing 12 are in contact with each other. Furthermore, when the first connecting portions 31, 32, 33 are arranged at the second predetermined position, and the second connecting portions 34, 35 are moved to the link fully closed position, as shown in FIG. The vertical wind direction adjusting blade 30 and the arms 75a and 75b are in contact with each other.

  Further, the second protrusion mechanisms 71a, 71b are configured such that the positions of the first connecting portions 31, 32, 33 are a first predetermined position, a second predetermined position, or a predetermined distance from the first predetermined position to the second predetermined position. In this case, the second connecting portions 34 and 35 can be moved using the support shafts 47, 57, and 67 pivotally supported by the first connecting portions 31, 32, and 33 as rotation axes. . For example, when the support shafts 47, 57, 67 are arranged at the first predetermined position so as not to move, the second protrusion mechanisms 71a, 71b move the support shafts 78a, 78b to move the second The distance between the connecting portions 34 and 35 and the second motors 73a and 73b can be changed (see FIGS. 5, 6, 8, 9, and 10). For this reason, the second protrusion mechanisms 71a and 71b arrange the second connecting portions 34 and 35 at positions different from the link fully closed position or the link fully open position, or link the positions of the second connecting portions 34 and 35 to each other. It is possible to change between the fully closed position and the link fully open position. In this way, the second ejection mechanisms 71a and 71b change the positions of the second connecting portions 34 and 35 around the support shafts 47, 57, and 67 as the rotation shafts, thereby allowing the air outlet 15 It is possible to adopt a predetermined posture that is arranged to be inclined at a predetermined angle with respect to the opening surface, or to swing the vertical wind direction adjusting blade 30.

  In addition, in this embodiment, even if the indoor unit 10 moves the 2nd connection parts 34 and 35 to a link full open position, when the 1st connection parts 31, 32, and 33 are arrange | positioned in the 1st predetermined position, The vertical wind direction adjusting blade 30 and the indoor unit casing 12 are configured not to cause structural interference (see FIG. 8). Moreover, in this embodiment, when the indoor unit 10 moves the second connection parts 34 and 35 to the link fully closed position when the first connection parts 31, 32, and 33 are arranged at the first predetermined position, The vertical wind direction adjusting blade 30 and the indoor unit casing 12 are configured to cause structural interference (see FIG. 9). Furthermore, in this embodiment, the indoor unit 10 is configured such that when the first connecting portions 31, 32, and 33 are disposed at the second predetermined position, the second connecting portions 34 and 35 are connected to the link fully opened position and the link fully closed. Regardless of the position, the vertical airflow direction adjusting blade 30 and the indoor unit casing 12 are configured not to cause structural interference (see FIG. 10).

  With such a configuration, the blade moving mechanism 50 can change the posture of the up / down airflow direction adjusting blade 30 by moving the first connecting portions 31, 32, 33 and the second connecting portions 34, 35. In the present embodiment, when the first connecting portions 31, 32, 33 are moved, the positions of the second connecting portions 34, 35 are moved along with the movement of the first connecting portions 31, 32, 33. It is assumed that the positions of the first connecting parts 31, 32, 33 are not moved even if the second connecting parts 34, 35 are moved.

  The blade moving mechanism 50 has a mounting plate 80. The mounting plate 80 is disposed above the opening surface of the air outlet 15 and is fixed to the indoor unit casing 12. Further, one first motor 54 and two second motors 73a and 73b are fixed to the upper surface of the mounting plate 80. In this way, the first motor 54 and the second motors 73 a and 73 b are housed inside the indoor unit casing 12 together with the mounting plate 80.

  Next, the control part 84 which controls the drive of the 1st motor 54 and the 2nd motor 73a, 73b is demonstrated.

<Control unit>
FIG. 11 is a control block diagram of the control unit 84 included in the air conditioner.

  As shown in FIG. 11, the control unit 84 is connected to various devices such as the indoor unit 10 and the outdoor unit 2, and performs cooling operation or heating based on an operation command or the like from the air conditioning target person via the remote controller 86. Operation control of various devices according to each operation such as operation is performed.

  The control unit 84 includes a reception unit 81, a setting unit 82, a storage unit 83, a determination unit 88, a determination unit 87, and a drive control unit 85.

  The receiving unit 81 receives, as a control signal, a command for the air conditioner transmitted from the air conditioning subject via the remote controller 86 or the like. The command includes, for example, a wind direction setting command. The wind direction setting command is a command issued by the air conditioning subject in order to set the blowing direction of the air blown out from the indoor unit 10.

  The setting unit 82 sets the posture to be taken by the vertical wind direction adjusting blades 30 based on the control signal related to the wind direction setting command received by the receiving unit 81. Further, the setting unit 82 further sets the positions of the first connecting parts 31, 32, 33 and the second connecting parts 34, 35 based on the set posture.

  Each time the setting unit 82 newly sets the positions of the first connecting parts 31, 32, 33 and the second connecting parts 34, 35, the storage unit 83 stores the current first connecting parts 31, 32, 33 and The position information of the second connecting parts 34 and 35 is stored. Therefore, the storage unit 83 stores the current position information of the first connecting units 31, 32, 33 and the second connecting units 34, 35 as position information.

  The determination unit 88 determines whether or not the movement of the first coupling units 31, 32, 33 and the second coupling units 34, 35 is necessary when the posture of the up / down airflow direction adjusting blade 30 is changed. Specifically, the determination unit 88 includes information regarding the positions of the first coupling units 31, 32, 33 and the second coupling units 34, 35 set by the setting unit 82, and the first stored in the storage unit 83. The position information of the connecting parts 31, 32, 33 and the second connecting parts 34, 35 is compared, and it is determined whether or not the first connecting parts 31, 32, 33 and the second connecting parts 34, 35 need to be moved. to decide.

  Based on the determination result of the determination unit 88, the determination unit 87 determines the operation content of the up / down wind direction adjusting blade 30 as the first operation or the second operation. Specifically, the determination unit 87 determines that the determination unit 88 needs to move only the first connection unit 31, 32, 33, and the first connection unit 31, 32, 33 and the second connection unit. When it is determined that the movement of the connecting portions 34 and 35 is necessary, the operation content is determined to be the first operation. Further, when the determination unit 88 determines that only the movement of the second coupling units 34 and 35 is necessary, the determination unit 87 determines the operation content as the second operation.

  The first operation includes a first connecting portion moving operation and a second connecting portion origin correcting operation. The first operation is performed in the order of the first connecting portion moving operation and the second connecting portion origin correcting operation. The first connecting portion moving operation is an operation in which the first connecting portions 31, 32, 33 are moved from the current position to a predetermined position set by the setting portion 82. The second connecting portion origin correcting operation is an operation in which the second connecting portions 34 and 35 are moved from the current position to the origin position and further moved from the origin position to a predetermined position set by the setting unit 82. That is. The origin position is a reference position when the driving of the second motors 73a and 73b is controlled.

  The second operation includes a second connecting portion moving operation. The second connecting portion moving operation is an operation in which the second connecting portions 34 and 35 are moved from the current position to a predetermined position. Note that the second operation does not include an operation in which the first coupling portions 31, 32, and 33 are moved. Further, the second operation does not include an operation in which the second connecting portions 34 and 35 are moved to the origin position.

  Furthermore, when the determination unit 87 determines that the operation content of the up / down airflow direction adjusting blade 30 is the first operation, based on the positions of the first connection units 31, 32, 33, the origins of the second connection units 34, 35 are determined. Determine the position. Specifically, the determination unit 87 sets the origin position of the second connection units 34 and 35 based on the positions of the first connection units 31, 32, and 33 set by the setting unit 82 to the link fully open position or the link fully closed state. The position is determined as one of the positions. More specifically, the determination part 87 determines the origin position of the 2nd connection parts 34 and 35 to a link full open position, when the 1st connection parts 31,32,33 are set to the 1st predetermined position. . Moreover, the determination part 87 determines the origin position of the 2nd connection parts 34 and 35 to a link fully closed position, when the 1st connection parts 31,32,33 are set to the 2nd predetermined position.

  Here, the determination of the origin position by the determination unit 87 is performed based on an origin position determination program created based on the structure of the indoor unit 10 and the condition of the room in which the indoor unit 10 is installed. The origin position determination program is stored in the storage unit 83 in advance. Note that the origin position determination program in the present embodiment is designed by performing simulation, desktop calculation, experiment, or the like based on the structure of the indoor unit 10 or the like. The structure of the indoor unit 10 is an arrangement relationship between members other than the vertical air direction adjusting blades 30 in the indoor unit 10 and the vertical air direction adjusting blades 30. Furthermore, the indoor situation in which the indoor unit 10 is installed refers to indoor structures that may be located in the vicinity of the up-and-down air direction adjusting blades 30 and the indoor unit 10 when the indoor unit 10 is installed ( For example, the arrangement relationship with a curtain rail or the like.

  The drive control unit 85 controls the rotation speed and rotation direction of the first motor 54 and the two second motors 73a and 73b, so that the first ejection mechanism 41, 51, 61 and the second ejection mechanism 71a, 71b is driven at an arbitrary timing. Specifically, the drive control unit 85 inputs a predetermined amount of positive or negative pulses to the first motor 54 and the second motors 73a and 73b, thereby causing the first ejection mechanisms 41, 51, 61 and the second ejection to occur. The mechanisms 71a and 71b are driven to move the first connecting parts 31, 32 and 33 and the second connecting parts 34 and 45 to predetermined positions. For this reason, the drive control unit 85 determines whether or not the first coupling units 31, 32, 33 and the second coupling units 34, 45 are respectively disposed at predetermined positions set by the setting unit 82. 54 and the number (number) of pulses input to the second motors 73a and 73b. The drive control unit 85 inputs a predetermined pulse to the first motor 54 with the rack fully closed position as the origin position of the first coupling units 31, 32, 33. In addition, the drive control unit 85 inputs a predetermined pulse to the second motors 73a and 73b with the link fully open position or link fully closed position as the origin position of the second coupling units 34 and 35.

  Further, the drive control unit 85 can independently control the first motor 54 and the two second motors 73a and 73b. For this reason, the first protrusion mechanisms 41, 51, 61 and the second protrusion mechanisms 71a, 71b can be driven independently.

  Further, the drive control unit 85 controls the driving of the first ejection mechanisms 41, 51, 61 and the second ejection mechanisms 71a, 71b based on the operation content determined by the determination unit 87. Specifically, when the operation content is determined to be the first operation by the determination unit 87, the drive control unit 85 first sets the first coupling units 31, 32, 33 from the current position by the setting unit 82. The drive of the first ejection mechanisms 41, 51, 61 is controlled so as to be moved to the predetermined position. Next, the drive control unit 85 uses the support shafts 47, 57, and 67 that are pivotally supported by the first connection units 31, 32, and 33 disposed at predetermined positions as the rotation shafts, and the second connection unit 34, The second projecting mechanism is configured so that 35 is moved from the current position to the origin position (link fully open position or link fully closed position) and then moved from the origin position to a predetermined position set by the setting unit 82. The drive of 71a, 71b is controlled (equivalent to origin correction control). In addition, when the operation content is determined to be the second operation by the determination unit 87, the drive control unit 85 is arranged at the first connection unit 31, 32, 33 arranged at a predetermined position set by the setting unit 82. The second connection portion 34, 35 is moved from the current position to a predetermined position set by the setting portion 82, with the support shafts 47, 57, 67 supported by The drive of the delivery mechanisms 71a and 71b is controlled. In this way, the first connecting portions 31, 32, 33 and the second connecting portions 34, 35 are moved to the predetermined positions set by the setting portion 82, so that the attitude of the up-and-down air direction adjusting blade 30 is increased. Is changed.

<Features>
(1)
In the above embodiment, when the operation content is determined to be the first operation by the determination unit 87, first, the first coupling units 31, 32, 33 are moved from the current position to the predetermined position set by the setting unit 82. The drive of the first ejection mechanisms 41, 51, 61 is controlled so as to be moved. Then, after the first connecting portions 31, 32, 33 are moved to the predetermined positions set by the setting portion 82, the second connecting portions 34, 35 are moved from the current position to the origin position (link fully open position or link all open position). The second projection mechanisms 71a and 71b are controlled to be moved from the origin position to a predetermined position set by the setting unit 82. For this reason, when the position of the 1st connection part 31,32,33 and the 2nd connection part 34,35 is moved so that the up-and-down wind direction adjustment blade 30 may take a predetermined attitude | position, 1st connection part 31,32, Even if the positions of the second connecting portions 34 and 35 are moved along with the movement of 33, the second connecting portions 31, 32, and 33 are moved to the predetermined positions set by the setting portion 82, and then the second connecting portions are moved. By moving the parts 34 and 35 to the origin position, the second connecting parts 34 and 35 can be temporarily arranged at a reference position. Therefore, even when the first connecting portions 31, 32, 33 and the second connecting portions 34, 35 move relative to each other, the second connecting portions 34, 35 are arranged at the origin position which is a reference position. After that, by moving to a predetermined position set by the setting unit 82, it is possible to reduce the possibility of being displaced from the predetermined position set by the setting unit 82.

  As a result, the vertical wind direction adjusting blade 30 can easily take a desired posture.

  Moreover, in the said embodiment, when it is judged by the judgment part 88 that the movement of the 1st connection part 31,32,33 and the 2nd connection part 34,35 is required, the operation | movement content of the up-and-down air direction adjustment blade 30 Is determined as the first operation. For this reason, whenever the 1st connection part 31,32,33 is moved, the 2nd connection part 34,35 can be moved to an origin position.

(2)
In the said embodiment, the 2nd connection parts 34 and 35 are moved by using the support shafts 47, 57, and 67 pivotally supported by the 1st connection parts 31, 32, and 33 as a rotating shaft. For this reason, in the indoor unit 10, the first connecting portions 31, 32, and 33 are arranged in the movement range of the second connecting portions 34 and 35 that can move the second connecting portions 34 and 35 without causing structural interference. It depends on where it is.

  So, in the said embodiment, when the operation content of the up-and-down wind direction adjustment blade | wing 30 is determined to be 1st operation | movement, based on the position of 1st connection part 31,32,33, it is the 2nd connection part 34,35. The origin position is determined as one of the link fully open position and the link fully closed position. For this reason, for example, when the origin positions of the second coupling parts 34 and 35 in the origin correction control are determined to be positions on the side where no structural interference occurs with respect to the positions of the first coupling parts 31, 32 and 33. Can move the second connecting portions 34 and 35 to the origin position without causing structural interference or the like. In addition, the second connecting portions 34 and 35 are moved in the direction toward the origin position determined by the determining portion 87. Therefore, based on the position of the 1st connection parts 31, 32, and 33, the moving direction of the 2nd connection parts 34 and 35 can be changed.

  This can reduce the possibility of structural interference.

(3)
In the above embodiment, the determination of the origin position by the determination unit 87 is based on the origin position determination program. The origin position determination program is created based on the structure of the indoor unit 10 and the situation of the room where the indoor unit 10 is installed. For this reason, for example, the origin position determination program is designed by the designer, and the origin position is set so that the vertical air direction adjusting blade 30 and the indoor unit casing 12 do not cause structural interference in consideration of the structure of the indoor unit 10. The origin position is determined so that the up / down airflow direction adjusting blade 30 and the indoor structure do not interfere with each other in consideration of the installation situation in the room where the indoor unit 10 is installed. When designed in such a manner, in the origin correction control, it is possible to reduce the possibility that the vertical wind direction adjusting blade 30 interferes with members other than the vertical wind direction adjusting blade 30. Therefore, in the origin correction control, it is possible to reduce the possibility that the second coupling parts 34 and 35 are not moved to the origin position due to the structure interference. Thus, the optimal origin position can be selected and determined according to the structural constraints and installation constraints of the indoor unit 10.

  In the above embodiment, due to the structure of the indoor unit 10, when the first connecting parts 31, 32, 33 are arranged at the first predetermined position, the second connecting parts 34, 35 are moved to the link fully closed position. And the up-and-down wind direction adjusting blade 30 and the indoor unit casing 12 are configured to cause structural interference. For this reason, the origin position determination program allows the determination unit 87 to determine the second connection units 34 and 35 when the first connection units 31, 32, and 33 are arranged at the first predetermined position in the origin correction control. Designed to determine the origin position as the link fully open position. Moreover, in the said embodiment, when the 1st connection parts 31,32,33 are arrange | positioned in the 2nd predetermined position on the structure of the indoor unit 10, the up-and-down wind direction adjustment blade 30 and the indoor unit casing 12 are structures. The second connecting portions 34 and 35 can be moved to either the link fully closed position or the link fully open position without causing interference. However, when the first connecting parts 31, 32, 33 are arranged at the second predetermined position, if the second connecting parts 34, 35 are moved to the link fully open position, the up / down airflow direction adjusting blade 30 and the indoor unit 10 are installed. It is assumed that there is a risk of interference with indoor structures (for example, curtain rails, etc.). For this reason, the origin position determination program allows the determination unit 87 to determine the second connection units 34 and 35 when the first connection units 31, 32, and 33 are arranged at the second predetermined position in the origin correction control. It is designed to determine the origin position as the link fully closed position. Therefore, in the origin correction control, the determination unit 87 determines the origin position of the second connection unit 34, 35 as the link fully open position when the first connection unit 31, 32, 33 is disposed at the first predetermined position. And when the 1st connection parts 31, 32, and 33 are arrange | positioned in the 2nd predetermined position, the origin position of the 2nd connection parts 34 and 35 is determined to a link fully closed position.

  By moving the second connecting portions 34 and 35 in the moving direction toward the origin position determined in this way, it is possible to reduce the possibility that the vertical wind direction adjusting blade 30 interferes with members other than the vertical wind direction adjusting blade 30. ing.

(4)
In the said embodiment, 2nd protrusion mechanism 71a, 71b is provided with link mechanism 72a, 72b. Therefore, when the second motors 73a and 73b are driven, the swing levers 74a and 74b and the arms 75a and 75b can be driven, so that the positions of the second connecting portions 34 and 35 can be moved.

  Thereby, the position of the 2nd connection parts 34 and 35 can be moved with easy composition.

(5)
In the said embodiment, the position of the 2nd connection parts 34 and 35 is correct | amended by moving the 2nd connection parts 34 and 35 to the origin position which is a reference | standard position. For this reason, the position of the 2nd connection parts 34 and 35 can be estimated even if it does not provide position detection means, such as a limit switch.

<Modification>
(A)
In the above embodiment, the origin position determination program is designed based on the structure of the indoor unit 10 and the situation (predetermined condition) in the room where the indoor unit 10 is installed.

  Alternatively, the origin position determination program may be designed based on the structure of the indoor unit and other conditions. As other conditions, the movement time required for the second connecting part to move to the predetermined position set by the setting part or the second connecting part is changed by moving to the origin position. For example, the posture of the vertical airflow direction adjusting blade.

  First, the case where the origin position determination program is designed based on the structure of the indoor unit and the movement time will be described.

  For example, due to the structure of the indoor unit, when the second connecting portion is moved in either the direction toward the link fully open position or the direction toward the link fully closed position, the members other than the vertical airflow direction adjustment blades constituting the indoor unit If the wind direction adjusting blade does not interfere, the origin position is based on the time required for the second connecting part to move from the current position to the predetermined position set by the setting part via the origin position. The origin position determination program may be designed so that is determined. Thus, when the origin position determination program is designed, the determination unit moves the second connecting unit from the current position to a predetermined position set by the setting unit via the link fully closed position. The travel time required in the case of being moved is compared with the travel time required when moving from the current position to the predetermined position set by the setting unit via the link fully open position. The origin position is determined so that the second connecting portion is moved in the moving direction with the shorter moving time. For this reason, compared with the case where the origin position of a 2nd connection part is determined irrespective of movement time, the execution time of origin correction control can be shortened.

  Next, a case where the origin position determination program is designed based on the structure of the indoor unit and the attitude of the up / down air direction adjusting blades will be described. Due to the structure of the indoor unit, it is possible to adjust the vertical air direction and the members other than the vertical air direction adjusting blades constituting the indoor unit even if the second connecting portion is moved in either the direction toward the link fully open position or the direction toward the link fully closed position. If the blade does not interfere, the origin position is determined so that the origin position is determined based on the attitude of the vertical airflow direction adjustment blade that changes as the second connecting portion is moved from the position where it is currently arranged to the origin position. A position determination program may be designed.

  For example, in the case where the origin position determination program is designed so that the origin position is determined so that the blown air (conditioned air) is not directly blown to the air conditioning target person, the conditioned air is not directly blown to the air conditioning target person. While adopting such a posture, the second connecting portion can be moved so that the posture of the vertical airflow direction adjusting blade changes. For this reason, the possibility that the blown air is directly blown onto the air-conditioning target person can be reduced. Specifically, for example, when the first connecting portion is arranged at the second predetermined position, the second connecting portion is moved to the link fully open position, so that the vertical wind direction adjusting blades directly blow out to the air-conditioning target person. Adopt a posture that is likely to be blown air. For this reason, when the origin position determination program is designed so that the origin position of the second connection part is determined as the link fully closed position when the first connection part is arranged at the second predetermined position. In the origin correction control, the second connecting unit is moved from the currently arranged position to the link fully closed position, and further moved from the link fully closed position to a predetermined position set by the setting unit. Therefore, the possibility that the conditioned air blown from the air outlet is directly blown to the air-conditioning subject can be reduced.

  Thereby, the possibility that the air-conditioning subject feels uncomfortable can be reduced.

  In addition, as another condition, a demonstration or the like for making it easy for the user to understand the driving of the up / down airflow direction adjusting blades when the air conditioner is activated may be considered. The origin position determination program may be designed based on all conditions of the structure of the indoor unit, the condition of the room in which the indoor unit is installed, the movement time, and the posture of the up / down air direction adjusting blade.

  Furthermore, the origin position determination program may be designed based only on the structure of the indoor unit. Specifically, the origin position determination program may be designed so that the origin position of the second connection portion is determined based only on the position of the first connection portion. For example, the indoor unit moves the second connecting portion to the link fully closed position when the first connecting portion is arranged at the first predetermined position, and the first connecting portion is arranged at the second predetermined position. In the case where it is configured so that structural interference occurs only when the second connecting portion is moved to the link fully open position, the first connecting portion is disposed at the first predetermined position. The origin position of the second connecting portion is determined to be the fully open position of the link, and when the first connecting portion is disposed at the second predetermined position, the origin position of the second connecting portion is determined to be the fully closed position of the link. In addition, an origin position determination program is designed. When the origin position determination program is designed in this way, the movement direction of the second connecting portion to the origin position in the origin correction control can be determined based only on the position of the first connecting portion.

(B)
In the above embodiment, the origin positions of the second coupling parts 34 and 35 are determined based on the origin position determination program stored in the storage unit 83 in advance.

  Instead of this, users including air conditioning subjects and indoor unit installation workers may be able to set the origin position of the second connecting portion.

  For example, as shown in FIG. 12, a case will be described in which the indoor unit main body 11 is provided with an input unit 89 (corresponding to a setting unit) that allows the user to set the origin positions of the second coupling units 34 and 35. In addition, since it is the same as that of the said embodiment except the input part 89 being further provided, in FIG. 12, about the structural member other than the input part 89, the code | symbol similar to the said embodiment is attached | subjected. In addition, since the configuration other than the input unit 89 and the determination unit 87 is the same as that of the above embodiment, the description thereof is omitted.

  The input unit 89 is a switch that can set the origin position of the second coupling units 34 and 35. The user can set the origin positions of the second coupling parts 34 and 35 by inputting the origin positions of the second coupling parts 34 and 35 to the input unit 89. In this modification, the input unit 89 is provided in the indoor unit main body 11, but the present invention is not limited to this, and the input unit may be provided in another component such as a remote controller.

  When determining the origin position of the second coupling units 34 and 35 in the origin correction control, the determination unit 87 first determines whether or not there is an input in the input unit 89. If the determination unit 87 determines that there is no input of the origin position in the input unit 89, the origin of the second coupling units 34 and 35 is based on the origin position determination program stored in the storage unit 83 in advance. Determine the position. Further, when determining that the origin position is input from the input unit 89, the determination unit 87 determines the origin position of the second coupling units 34 and 35 to be the origin position input to the input unit 89. As described above, when the origin position set by the user has priority over the preset origin position, the origin positions of the second connecting portions 34 and 35 in the origin correction control are determined according to the convenience of the user. Can be set. For this reason, the origin position of the 2nd connection parts 34 and 35 can be set according to the indoor condition etc. in which the indoor unit 10 is installed.

  Thereby, the installation restrictions of the indoor unit 10 can be reduced.

(C)
In the above embodiment, the air outlet 15 is formed on the bottom surface of the indoor unit casing 12.

  Instead of this, the air outlet may be formed continuously from the bottom surface to the side surface of the indoor unit casing. Moreover, when the blower outlet is continuously formed from the bottom surface to the side surface of the indoor unit casing, a side shielding member capable of opening and closing the side surface side of the blower outlet may be provided.

  The present invention can be applied to an indoor unit of an air conditioner because the horizontal blade can be moved so that the horizontal blade can easily take a desired posture.
