Moreover, the accommodating part 95 is arrange | positioned in the 2nd part 17a vicinity of the blower outlet 15 in the blowing flow path (refer FIG. 3). For this reason, the blowout flow path is divided into three flow paths by the storage portions 25 and 95 at the lower part thereof. Here, for convenience of explanation, the outlet of the outlet channel is defined by the upper ends of the two storage portions 25 and 95, and the outlet of the outlet channel is the first part 16 of the outlet 15. It is called channel B. Further, in the blowing channel, the channel portion in which the upper end portion of the storage portion 25 is located at the inlet and the outlet is the third portion 17b of the outlet 15 is referred to as the right blowing channel D. Further, in the blowout flow path, the flow path portion in which the upper end portion of the storage portion 95 is located at the inlet and the outlet thereof is the second portion 17a of the blowout opening 15 is referred to as the left blowout flow path C. For this reason, in this indoor unit 10, the outlet of the main blowing channel B is blocked by the vertical airflow direction adjusting blade 30, the outlet of the left blowing channel C is blocked by the right side shielding member 20, and the right side shielding member 20. Thus, the outlet of the right blowing channel D is closed. Further, when the side shielding members 20 and 90 are in the open state, the side shielding members 20 and 90 are arranged at positions away from the right blowing channel D and the left blowing channel C. For this reason, in this indoor unit 10, when the side shielding members 20 and 90 are in the open state, the side shielding members 20 and 90 are blown out from the second portion 17a and the third portion 17b of the air outlet 15. It has a configuration that does not affect the conditioned air. Therefore, the conditioned air flowing through the right side outlet channel D and the left side outlet channel C is regulated by the channel forming member forming the right side outlet channel D and the left side outlet channel C, It blows off from the 2nd part 17a and the 3rd part 17b of the blower outlet 15 which opens toward.

Further, as shown in FIG. 3, the first forming members 26 and 96 are a part of the flow path forming members that form the right side blowing flow path D and the left side blowing flow path C, and together with the indoor unit casing 12. A right side outlet channel D and a left side outlet channel C are formed.
The second forming members 27 and 97 are disposed on the lower side of the first forming members 26 and 96 so as not to interfere with the side shielding members in the open state. Further, the up / down airflow direction adjusting blade 30 in the closed state is disposed below the second forming members 27 and 97.

<First moving mechanism>
The first moving mechanism 50 moves the vertical airflow direction adjusting blade 30 so that the first portion 16 of the air outlet 15 is opened from the state where the first portion 16 of the air outlet 15 is shielded. Mechanism. Further, the first moving mechanism 50 can switch the state (posture) of the vertical air direction adjusting blade 30 by changing the position of the vertical air direction adjusting blade 30 with respect to the opening surface corresponding to the first portion 16 at the air outlet 15. it can.
The first moving mechanism 50 includes protruding mechanisms 41, 51, 61 and angle adjusting mechanisms 71a, 71b.

By moving the first connecting portions 31, 32, and 33, the vertical airflow direction adjusting blade 30 can be slid, that is, moved out.

Further, the pushing-out mechanisms 41, 51, 61 are rack / pinion mechanisms, and have pinion gears 42, 52, 62 and moving members 43, 53, 63 as shown in FIGS. ing. Each pinion gear 42, 52, 62 is connected to a drive shaft 54 a included in a push-out mechanism drive motor 54 described later, and rotates when the push-out mechanism drive motor 54 is driven. The moving members 43, 53, and 63 have racks 46, 56, and 66 that mesh with the pinion gears 42, 52, and 62, and support shafts 47, 57, and 67, respectively. The racks 46, 56, 66 are provided from the vicinity of one end of the moving members 43, 53, 63 to the vicinity of the other end. The support shafts 47, 57, and 67 are inserted through the shaft support portions of the first connecting portions 31, 32, and 33 of the vertical airflow direction adjustment blade 30 in parallel with the longitudinal direction of the vertical airflow direction adjustment blade 30. The wind direction adjusting blade 30 is rotatably supported.

Further, the protrusion mechanisms 41, 51, 61 have one protrusion mechanism driving motor 54. A drive shaft 54 a that rotates when the drive mechanism driving motor 54 is driven is connected to the drive mechanism drive motor 54. Further, as described above, the pinion gears 42, 52, 62 of the projecting mechanisms 41, 51, 61 are connected to the drive shaft 54a. For this reason, the push-out mechanism drive motor 54 can rotate the pinion gears 42, 52, and 62 by rotating the drive shaft 54a. The protrusion mechanism driving motor 54 is fixed to a mounting plate 80 described later.
With such a configuration, in the projection mechanisms 41, 51, 61, when the projection mechanism driving motor 54 rotates the pinion gears 42, 52, 62, the racks 46, 56, meshing with the pinion gears 42, 52, 62, Power is transmitted to 66, and the positions of the moving members 43, 53, 63 with respect to the pinion gears 42, 52, 62 change. For this reason, the up-and-down air direction adjusting blade 30 moves in the direction toward the opening surface corresponding to the first portion 16 in the air outlet 15 or the first portion 16 in the air outlet 15 as the moving members 43, 53, and 63 move. It moves in the direction away from the opening surface corresponding to. Note that the rotation amount and the rotation direction of the protrusion mechanism driving motor 54 are controlled by the control unit 84 described later.

In addition, the angle adjustment mechanisms 71 a and 71 b are angle-adjusted with the vertical wind direction adjustment blade 30 so that the front-rear inclination angle with respect to the opening surface corresponding to the first portion 16 is adjusted at the outlet 15 of the vertical wind direction adjustment blade 30. The 2nd connection parts 34 and 35 which are the parts with which the mechanisms 71a and 71b are connected are moved.
The angle adjustment mechanisms 71a and 71b include angle adjustment mechanism drive motors 73a and 73b and link mechanisms 72a and 72b.
The angle adjustment mechanism drive motors 73a and 73b have drive shafts 79a and 79b. The angle adjustment mechanism drive motors 73a and 73b are stepping motors, and drive the link mechanisms 72a and 72b via the drive shafts 79a and 79b. The link mechanisms 72a and 72b have swing levers 74a and 74b and arms 75a and 75b. One end of the swing levers 74a and 74b is disposed in the vicinity of the drive shafts 79a and 79b, and swings as the drive shafts 79a and 79b rotate. The other ends of the swing levers 74a and 74b are rotatably connected to one ends of the arms 75a and 75b. Further, support shafts 78a and 78b are formed in the arms 75a and 75b in the vicinity of the ends opposite to the ends connected to the swing levers 74a and 74b. The support shafts 78a and 78b are respectively engaged with the shaft support portions of the second connecting portions 34 and 35 of the up / down air direction adjusting blade 30, and support the up / down air direction adjusting blade 30 in a rotatable manner.

With such a configuration, the angle adjusting mechanisms 71a and 71b can push and pull the second connecting portions 34 and 35 of the vertical airflow direction adjusting blade 30 by driving the angle adjusting mechanism driving motors 73a and 73b. The rotation angles of the link mechanisms 72a and 72b, that is, the rotation amounts and the rotation directions of the angle adjustment mechanism driving motors 73a and 73b are controlled by the control unit 84 described later.
Further, the first moving mechanism 50 has a mounting plate 80. The attachment plate 80 is disposed above the opening surface corresponding to the first portion 16 at the air outlet 15. Further, on the upper surface of the mounting plate 80, one protrusion mechanism driving motor 54 and two angle adjusting mechanism driving motors 73a and 73b are fixed. Specifically, the protrusion mechanism driving motor 54 is fixed in the vicinity of the left end portion of the mounting plate 80. Further, the angle adjustment mechanism driving motors 73a and 73b are fixed to the substantially central portion of the mounting plate 80, respectively. Thus, the protrusion mechanism drive motor 54 and the angle adjustment mechanism drive motors 73a and 73b are housed inside the indoor unit casing 12 together with the mounting plate 80.

<Second moving mechanism>
FIG. 12 is a perspective view of the vicinity of the right side shielding member 20. FIG. 13 is a conceptual diagram of the second moving mechanism 29 in a side view of the indoor unit 10. In FIG. 12, the front part of the indoor unit casing 12 and the storage part 25 are omitted. Further, the alternate long and short dash line in FIG. 13 indicates the rotation axis of the right side shielding member 20.
The second moving mechanisms 29 and 99 are moving mechanisms different from the first moving mechanism 50, and the second portion 17 a and the third portion 17 b of the air outlet 15 are shielded from the second state of the air outlet 15. This is a mechanism capable of moving the side shielding members 20 and 90 so that the portion 17a and the third portion 17b are opened. In other words, the second moving mechanisms 29 and 99 are mechanisms for moving the side shielding members 20 and 90 in order to switch the state of the side shielding members 20 and 90. Specifically, the second moving mechanisms 29 and 99 set the side shielding members 20 and 90 in the closed state to the indoor unit main body so that the state of the side shielding members 20 and 90 is switched from the closed state to the open state. 11 is moved toward the center in the left-right direction. Further, at this time, the second moving mechanisms 29 and 99 move the side shielding members 20 and 90 so that the side shielding members 20 and 90 are disposed above the vertical airflow direction adjusting blades 30.

Next, the configuration of the second moving mechanisms 29 and 99 will be described. The second moving mechanisms 29 and 99 include a second moving mechanism 29 for switching the state of the right side shielding member 20 and a second moving mechanism 99 for switching the state of the left side shielding member 90. The second moving mechanism 99 is the same as the configuration in which the configuration of the second moving mechanism 29 is bilaterally symmetric. Therefore, only the configuration of the second moving mechanism 29 will be described here, and the configuration of the second moving mechanism 99 will be described. Description of is omitted.
The second moving mechanism 29 includes a second moving mechanism driving motor 24, a support member 23, and a spring portion 28.
The second moving mechanism driving motor 24 is disposed outside the right side blowing channel D and is fixed to the indoor unit casing 12. Specifically, as shown in FIG. 13, the second moving mechanism driving motor 24 is located in the indoor unit casing 12 and behind the indoor unit casing 12 from the rear portion of the third portion 17 b of the air outlet 15. Has been placed.
The second moving mechanism driving motor 24 includes a driving shaft 24b that rotates when the second moving mechanism driving motor 24 is driven, and an interlocking lever 24a that rotates in conjunction with the driving shaft 24b. . The drive shaft 24b extends substantially in the front-rear direction of the indoor unit 10. Specifically, as illustrated in FIG. 13, the drive shaft 24 b is disposed so as to be inclined with respect to the front-rear direction of the indoor unit 10 such that the rear portion of the drive shaft 24 b is lower than the front portion.

The support member 23 includes a front support member 23a and a rear support member 23b. The lower end portion of the front support member 23 a is fixed in the vicinity of the second end portion 20 b of the right side shielding member 20. Further, the upper end portion of the front support member 23a is rotatably supported by the indoor unit casing 12. The lower end portion of the rear support member 23b is fixed in the vicinity of the first end portion 20a of the right side shielding member 20. Further, the upper end portion of the rear support member 23b is connected to a drive shaft 24b of the second moving mechanism drive motor 24. For this reason, the rear support member 23b can rotate around the drive shaft 24b as the drive shaft 24b rotates.
The spring part 28 includes a spring holding part 28a and a spring member 28b, a part of which is disposed on the outer peripheral surface of the spring holding part 28a. The spring holding portion 28a is provided to be rotatable around the drive shaft 24b. Further, a part of the spring holding portion 28a is connected to the rear support member 23b. Further, the spring holding portion 28a includes a locking pin 28c. The locking pin 28c protrudes from the spring holding portion 28a.

One end of the spring member 28b extends from the direction of the arrow X1 shown in FIG. 12 to the locking pin 28c, and the spring holding portion 28a is biased in the direction of the arrow X1 shown in FIG. 12 via the locking pin 28c. . The other end of the spring member 28 b is fixed to the indoor unit casing 12. For this reason, the spring member 28b always urges the rear support member 23b in the direction of the arrow X1 shown in FIG. 12 via the locking pin 28c.
With this configuration, in the second moving mechanism 29, the interlocking lever 24a presses the contact portion of the locking pin 28c against the biasing force of the spring member 28b by driving the second moving mechanism driving motor 24. By rotating in the arrow X2 direction in FIG. 12, the rear support member 23b rotates in the same direction. For this reason, the right side shielding member 20 moves in the direction of opening the third portion 17b of the air outlet 15 with the drive shaft 24b disposed at an inclination as the rotation axis. That is, the second moving mechanism driving motor 24 switches the state of the right side shielding member 20 from the closed state to the open state against the urging force of the spring member 28b. In this way, the first portion 21 of the right side shielding member 20 is stored in the storage space S. At this time, a part of the second portion 22 that is a portion of the right-side shielding member 20 that is not stored in the storage space S is a space that is located when the vertical airflow direction adjustment blade 30 is in a closed state. It arrange | positions at the 1st part 16 of the blower outlet 15. FIG.

Further, since the rear support member 23b is always urged in the direction of the arrow X1 shown in FIG. 12 by the spring member 28b, the right side shielding member 20 is urged in a direction in which the state is always closed. Therefore, in the second moving mechanism 29, the interlocking lever 24a rotates in the direction of the arrow X1 shown in FIG. 12 by driving the second moving mechanism driving motor 24, so that the locking pin 28c and The rear support member 23b rotates in the same direction. As a result, the right-side shielding member 20 moves in the direction of shielding the third portion 17b of the outlet 15 with the drive shaft 24b as the rotation axis.
In the second moving mechanism 99, the left-side shielding member 90 is switched from the closed state to the open state against the urging force of the spring member by driving the second moving mechanism driving motor 94, or the spring member It is switched from the open state to the closed state by the urging force. The driving of the second moving mechanism driving motors 24 and 94 is controlled by a control unit 84 to be described later.

<Control unit>
FIG. 14 is a control block diagram of the control unit 84 included in the air conditioner.
As shown in FIG. 14, the control unit 84 is connected to various devices such as the indoor unit 10 and the outdoor unit 2, and is based on an operation command from an air-conditioning target person via the remote controller 86, for cooling operation or heating operation. It is possible to perform operation control of various devices according to each operation mode.
The remote controller 86 is provided with a plurality of switches such as an operation stop / start button, an operation switching button, and a wind direction setting button 86a. The operation stop / start button is a switch that is operated when the operation of the air conditioner is stopped by the air conditioning subject or when the operation is started. The operation switching button is a switch that is operated when various operation modes such as a cooling operation or a heating operation of the air conditioner are set by the air conditioning subject. Furthermore, the wind direction setting button 86a is a switch that is operated when the blowing direction of the air blown out from the indoor unit 10 by the air conditioning subject is set. For example, when the wind direction setting button 86a is pressed by the air conditioning subject, the control unit 84 receives a wind direction setting command from the air conditioning subject as a control signal. In addition, in the wind direction setting command in this embodiment, the 1st command which is a command for setting the blowing direction of air so that conditioned air blows also to the side of the indoor unit 10, and conditioned air is sent to the person to be air-conditioned. A second command that is a command for setting the air blowing direction so as to blow out to the front upper side and the side of the indoor unit 10 so as not to hit directly is included. The first command of the wind direction setting command is a command issued only when the vertical wind direction adjusting blade 30 is in the second open state or the third open state.

The control unit 84 has a drive control unit 85. The drive control unit 85 controls the number of rotations and the rotation direction of the projection mechanism drive motor 54 and the two angle adjustment mechanism drive motors 73a and 73b, so that the projection mechanisms 41, 51, and 61 and the angle adjustment mechanism are controlled. 71a and 71b are driven at an arbitrary timing. Thereby, the state of the up-and-down wind direction adjusting blade 30 can be switched. Further, the drive control unit 85 drives the second moving mechanisms 29 and 99 at an arbitrary timing by controlling the rotation speed and the rotation direction of the second moving mechanism driving motors 24 and 94. Thereby, the state of the side shielding members 20 and 90 can be switched.
In addition, when switching the side shielding members 20 and 90 from the closed state to the open state, the drive control unit 85 adjusts the vertical wind direction so that the side shielding members 20 and 90 and the vertical wind direction adjusting blades 30 do not interfere with each other. After the blade 30 is switched from the closed state to the first open state, the second open state, or the third open state, the state of the side shielding members 20 and 90 is switched from the closed state to the open state. The drive control unit 85 switches the state of the up / down airflow direction adjusting blade 30 from the first open state, the second open state, or the third open state to the closed state. In the open state, after the side shielding members 20, 90 are switched from the open state to the closed state so that the side shielding members 20, 90 and the up / down air direction adjusting blades 30 do not interfere with each other, the up / down air direction The state of the adjustment blade 30 is switched from the first open state, the second open state, or the third open state to the closed state.

In addition, the control unit 84 transmits the control signal related to the received wind direction setting command, the control signal related to the operation mode setting command for the cooling operation or the heating operation, and the control signal related to the operation stop command to the drive control unit 85. And the drive control part 85 switches the state of the up-and-down wind direction adjustment blade | wing 30 and the side shielding members 20 and 90 based on the control signal transmitted from the control part 84. FIG.
For example, when a control signal related to the operation mode setting command for the cooling operation is transmitted from the control unit 84, the drive control unit 85 moves the first moving mechanism 50 so that the state of the up / down airflow direction adjusting blade 30 is in the second open state. Drive.
As a result, the conditioned air blown from the first portion 16 of the blower outlet 15 is regulated by the vertical airflow direction adjusting blades 30 and blown to the lower front side of the indoor unit 10.

Further, for example, when a control signal related to the operation mode setting command for the heating operation is transmitted from the control unit 84, the drive control unit 85 causes the first moving mechanism so that the state of the up / down airflow direction adjusting blade 30 becomes the third open state. 50 is driven.
As a result, the conditioned air blown from the first portion 16 of the blower outlet 15 is regulated by the vertical airflow direction adjusting blades 30 and blown out below the indoor unit 10.
Further, for example, when a control signal related to the first command is transmitted from the control unit 84, the drive control unit 85 causes the second moving mechanisms 29 and 99 so that the side shielding members 20 and 90 are in the open state. Drive.
As a result, the conditioned air that has reached the second portion 17 a and the third portion 17 b of the air outlet 15 is blown out toward the side of the indoor unit 10. At this time, since the drive control unit 85 does not drive the first moving mechanism 50, the state of the up / down airflow direction adjusting blade 30 is maintained in either the second open state or the third open state. Therefore, when the first command is issued from the air conditioning subject via the remote controller 86, the conditioned air is blown out to the side of the indoor unit 10 and to the front lower side or the lower side of the indoor unit 10.

For example, when a control signal related to the second command is transmitted from the control unit 84, the drive control unit 85 drives the first moving mechanism 50 so that the state of the up-and-down airflow direction adjusting blade 30 is in the first open state. At the same time, the second moving mechanisms 29 and 99 are driven so that the side shielding members 20 and 90 are in the open state.
As a result, the conditioned air blown from the first portion 16 of the blowout port 15 is regulated by the vertical airflow direction adjusting blades 30 and blown out to the upper front side of the indoor unit 10. In addition, the conditioned air that has reached the second portion 17 a and the third portion 17 b of the outlet 15 is blown out toward the side of the indoor unit 10.
Further, for example, when a control signal related to a cooling operation and a heating operation stop command is transmitted from the control unit 84, the drive control unit 85 is in a state where the vertical airflow direction adjusting blade 30 and the side shielding members 20 and 90 are closed. The first moving mechanism 50 and / or the second moving mechanisms 29 and 99 are driven so that

Accordingly, the air outlet 15 is shielded by the up / down airflow direction adjusting blade 30 and the side shielding members 20 and 90.

For this reason, at least a part of the side shielding members 20 and 90 in the open state can be accommodated. Furthermore, when the side shielding members 20 and 90 are in the open state, the first portion of the side shielding members 20 and 90 is housed in the housing space S, so that the side shielding from the outline of the indoor unit 10 is performed. The protrusion of the members 20 and 90 can be suppressed. Therefore, even when the side shielding members 20 and 90 are in the open state, the possibility that the appearance of the indoor unit 10 is damaged can be reduced.

Further, in the above embodiment, a part of the indoor unit casing 12 and the first forming member 26 form a right side blowing channel D through which air flows toward the third portion 17 b of the outlet 15. Further, a left side blowing passage C through which air toward the second portion 17a of the outlet 15 flows is formed by a part of the indoor unit casing 12 and the first forming member 96. Further, when the side shielding members 20 and 90 are in the open state, the side shielding members 20 and 90 are disposed at positions away from the right blowing channel D and the left blowing channel C. For this reason, for example, compared with the case where the side shielding member is in contact with the conditioned air flowing through the side blowing channel, the side shielding members 20 and 90 have the blowing channel D and the left blowing channel C. The possibility of contact with the flowing conditioned air can be reduced.
Thereby, the possibility that the side shielding members 20 and 90 are condensed can be reduced.

For example, the drive shaft and the rear support member may constitute a rack / pinion mechanism. Further, for example, the second moving mechanism may be a link mechanism.

-Second Embodiment-
FIG. 15 is an external perspective view of the indoor unit 110 when the operation of the air conditioner is stopped. FIG. 16 is an external perspective view of the indoor unit 110 when a heating operation is performed in the air conditioner. FIG. 17 is an external perspective view of the indoor unit 110 in a state where the heating operation is performed in the air conditioner and the side opening 117 is opened. 16 and 17, reference numeral 116 indicates an opening portion that is formed on the bottom surface of the indoor unit casing 112 at the air outlet 115 and can be covered by the vertical airflow direction adjusting blades 130.
An air conditioner according to a second embodiment of the present invention will be described. In addition, in this structure of an air conditioner, since structures other than the indoor unit 110 are the same structures as 1st Embodiment, description is abbreviate | omitted.

The indoor unit 110 is a wall-hanging indoor unit that is attached to an indoor wall surface or the like. In addition, the indoor unit 110 mainly includes an indoor unit main body 111, an up / down airflow direction adjusting blade 130, a first moving mechanism, and a second moving mechanism. In addition, since the structure of the up-and-down air direction adjustment blade | wing 130 and a 1st moving mechanism is the same structure as 1st Embodiment, description is abbreviate | omitted.
<Indoor unit configuration>
The indoor unit main body 111 mainly includes an indoor unit casing 112, an indoor heat exchanger, an indoor fan, and vertical blades. Further, in the indoor unit main body 111, the configurations of the indoor heat exchanger, the indoor fan, and the vertical blades are the same as those in the first embodiment, and thus the description thereof is omitted here.
The indoor unit casing 112 includes a casing main body 112a and a front panel 113. The casing body 112a is a substantially rectangular member that is long in the horizontal direction. The casing body 112a houses an indoor heat exchanger, an indoor fan, vertical blades, and the like. Further, an intake port (not shown) and an air outlet 115 are formed in the casing body 112a. The intake port is an opening for taking indoor air into the interior of the indoor unit casing 112, and is formed in the upper part of the casing body 112a.

The air outlet 115 is an opening for blowing out conditioned air in the indoor unit main body 111 and is formed in the vicinity of the lower part of the indoor unit 110. Specifically, the air outlet 115 is formed continuously from the bottom surface of the casing main body 112a to both side surfaces. For this reason, a part of the air outlet 115 is visible in the side view of the indoor unit 110.
The front panel 113 includes a front portion 113a and side portions 113b extending in the rear direction of the indoor unit body 111 from both ends of the front portion 113a. The front portion 113a can cover substantially the entire front side of the casing body 112a. The side portion 113b can cover a part of both side surfaces of the casing body 112a. Moreover, the side part 113b can cover the opening part (henceforth the side opening part 117) currently formed in the side surface of the casing main body 112a in the blower outlet 115. FIG.

The front panel 113 can take two states (a closed state and an open state).
When the front panel 113 is in the closed state, as shown in FIGS. 15 and 16, the side portion 113 b of the front panel 113 is disposed so as to cover the side opening 117.
Further, when the front panel 113 is in the open state, as shown in FIG. 17, the side portion 113 b of the front panel 113 is disposed so as to open the side opening 117. Specifically, when the front panel 113 is in an open state, the front panel 113 is disposed above the casing body 112a as compared to the position of the front panel 113 when the front panel 113 is in a closed state.
<Configuration of second moving mechanism>
The second moving mechanism is a moving mechanism different from the first moving mechanism, and the front panel 113 can be slid up and down with respect to the indoor unit body 111 in order to switch the state of the front panel 113. It is.

The second moving mechanism is disposed inside the indoor unit casing 112. The second moving mechanism is a rack / pinion mechanism that opens and closes the side opening 117 by moving the front panel 113 by the driving force of the driving unit. For this reason, the second moving mechanism functions as a conversion mechanism that converts the rotational motion transmitted from the drive unit into the opening / closing operation of the side opening 117, that is, the vertical motion of the front panel 113. In the present embodiment, the second moving mechanism is a rack / pinion mechanism, but is not limited thereto, and any mechanism that can slide the front panel in the vertical direction may be used. For example, the second moving mechanism may be another mechanism such as a link mechanism as long as the mechanism can slide the front panel in the vertical direction.
With this configuration, in the indoor unit 110, the side opening 117 can be opened by sliding the front panel 113 upward with respect to the indoor unit body 111.

Thereby, air can be blown out to the side as needed.
In addition, since the front panel 113 is slid in the vertical direction, the side opening 117 is shielded or opened, so that the front panel 113 can be prevented from projecting from the outer wall of the indoor unit 110 in the left-right direction. Therefore, when the front panel 113 is opened and closed, the amount of protrusion of the front panel 113 in the left-right direction from the outline of the indoor unit 110 can be suppressed.

Since the present invention is an invention of an indoor unit that can blow air to the side as needed, application to a wall-mounted indoor unit is effective.
