(Overview of indoor unit)
FIG. 1 is a front view of an indoor unit of an air conditioner according to an embodiment of the present invention, FIG. 2 is a bottom view of the indoor unit, FIG. 3 is a right side view of the indoor unit, and FIG. It is a perspective view which shows the indoor unit seen from diagonally lower right. In the indoor unit 1, five surfaces other than the front surface 1 a, the left side surface 1 b, the right side surface 1 c, the top surface 1 d and the bottom surface 1 e, that is, the back surface 1 f of the casing body 2 are covered with the decorative panel 5. In the following description, the direction from the rear surface 1f of the indoor unit 1 to the front surface 1a (front surface) is referred to as the front, and is along the direction connecting the left side surface 1b and the right side surface 1c of the indoor unit 1, that is, the longitudinal direction of the outlet 4. The direction is called the left-right direction.

  The indoor unit 1 includes a suction port 3 on the top surface 1d of the casing body 2 and a blower port 4 on the bottom surface 1e. FIG. 1 shows a state in which the horizontal blade 6 provided at the outlet 4 is closed. Normally, the air outlet 4 is closed when the operation is stopped, and the air outlet 4 is opened during the operation. However, the indoor unit 1 in FIG. 1 blows out conditioned air in the left-right direction even when the air outlet 4 is closed by the horizontal blades 6. It has a configuration that can. Details of the operation of the indoor unit 1 will be described later. In the following description, the expression “the horizontal blade 6 blocks the air outlet 4” is used to describe a state where there is no gap for blowing conditioned air between the air outlet 4 and the horizontal blade 6, and the horizontal blade 6 is The phrase “covering the air outlet 4” is used as an expression allowing the case where there is a gap for blowing out the conditioned air with or without a focus on the closing operation.

  In the indoor unit 1 shown in FIG. 1, indoor air is not sucked from the front surface 1 a, and the indoor unit 1 sucks indoor air exclusively from the suction port 3 on the top surface 1 d of the casing body 2. Therefore, the movement of the indoor air inside the indoor unit 1 is performed from the top surface 1d side of the indoor unit 1 toward the bottom surface 1e side of the indoor unit 1. As shown in FIG. 3, a cross flow fan 7 is provided inside the casing main body 2 of such an indoor unit 1 near the rear side at the substantially center of the casing main body 2 in a side view. An upstream V-shaped indoor heat exchanger (not shown) is arranged on the upstream side of the cross flow fan 7 in a side view, and the indoor heat exchanger is inserted before being sucked into the cross flow fan 7. Air conditioning is performed by passing room air. An air filter (not shown) is provided upstream of the indoor heat exchanger, and dust larger than the air filter gap is completely removed from the conditioned air guided to the crossflow fan 7. Although illustration is omitted, in the front view, the cross flow fan 7 has the same length as the suction port 3 and is long and horizontally disposed along the longitudinal direction of the casing body 2. In this way, the indoor heat exchanger is also used to efficiently perform indoor air conditioning by sucking indoor air and blowing out conditioned air by the crossflow fan 7 extending long in the longitudinal direction of the casing main body 2. It is formed in a shape that extends long in the longitudinal direction, and is disposed between the suction port 3 and the blower port 4 that extend long.

  Between the crossflow fan 7 and the blower outlet 4, as shown in FIG. 3, the blower channel | path 8 of a diffuser structure is provided. The guide surface 8a of the blow-out passage 8 has a smooth curve having a center of curvature on the side of the cross flow fan 7 in a side view, and the radius of curvature increases toward the lower side. Further, since the cross flow fan 7 rotates clockwise as viewed from the right side and its central axis is disposed toward the back surface 1f, the blowout passage 8 is located on the front side of the bottom surface 1e. It is formed obliquely toward Therefore, the conditioned air from the outlet passage 8 toward the outlet 4 has a directional vector from the top surface 1d toward the bottom surface 1e and a directional vector from the back surface 1f toward the front surface 1a. Become.

<Configuration of wind direction device>
A horizontal blade 6 is provided in front of the air outlet 4. The horizontal blade 6 can take two states, that is, when it is opened during operation and when it is operated while being closed. The indoor unit 1 can adjust the wind direction in the vertical direction of the indoor unit 1 by the horizontal blades 6. In this indoor unit 1, the horizontal blade 6 is opened when the air is blown forward from the air outlet 4 during heating and cooling, and the horizontal blade 6 is closed when the air is blown only right and left from the air outlet 4. FIG. 1 shows a state in which the air outlet 4 is closed with the horizontal blades 6 closed.

  FIG. 5 is a perspective view showing the indoor unit 1 as viewed from the lower left, and shows a state in which the horizontal blades 6 are removed for easy explanation of the internal structure of the blowout passage 8. A plurality of vertical blades 9 connected by vertical blade connecting rods 10 are swingably attached to the blowing passage 8. The surfaces 9 a of the plurality of vertical blades 9 swing left and right about a state perpendicular to the longitudinal direction of the casing body 2. These vertical blades 9 adjust the blowing direction of the conditioned air in the left-right direction by swinging or stopping at an arbitrary angle after swinging. Since the vertical blades 9 are connected by the two vertical blade connecting rods 10, they can be divided into two groups, a group A near the left side surface 1b and a group B near the right side surface 1c. The swinging direction is independent between group A and group B connected to different vertical blade connecting rods 10. For example, when group A is tilted to the right, group B may be tilted to the left. Further, in the group A and the group B, for example, even when they are tilted in the same direction, the tilt angles can be made different. Of course, the vertical blades 9 belonging to the group A and the group B can be swung in the same direction.

  In FIG. 5, the position indicated by the two-dot chain line 11 is an extension line of the ridge line that is a boundary between the bottom surface 1 e, the left side surface 1 b, and the right side surface 1 c. Conventionally, the bottom surface 1 e and the left side surface 1 b and the right side surface 1 c of the decorative panel 5 are usually separated at the two-dot chain line 11. The portion where the bottom surface 1e on the two-dot chain line 11 is recessed becomes an opening 12b for blowing to the left and an opening 12c for blowing to the right. The blower outlet 4 includes these openings 12b and 12c. The opening part 12a of the bottom face 1e of the blower outlet 4 is between these opening parts 12b and 12c. Thus, the blower outlet 4 has the left-side opening 12b and the right-side opening 12c in the indoor unit 1, and the shape of the horizontal blade 6 is configured to block the opening 12b and the opening 12c. .

  Next, the structure of the horizontal blade 6 will be described. FIG. 6A shows the front of the horizontal blade, FIG. 6B shows the bottom of the horizontal blade, and FIG. 6C shows the right side of the horizontal blade. Further, FIG. 7A shows a perspective view of the horizontal blade, and FIG. 7B shows a partially enlarged view of the right side surface portion as viewed obliquely from the upper left. The horizontal blade 6 includes a main body portion 6a, a left side surface portion 6b extending further to the left from the left end of the main body portion 6a, and a right side surface portion 6c extending further to the right from the right end of the main body portion 6a. In a closed state, the horizontal blade 6 is configured such that the left side surface portion 6b closes the opening portion 12a of the left side surface 1b, and the right side surface portion 6c closes the opening portion 12b of the right side surface 1c.

  The front end portion 6d and the rear end portion 6e of the horizontal blade 6 are connected in a substantially straight line between the left side surface portion 6b and the right side surface portion 6c in the main body portion 6a. The left end portion 6f of the left side surface portion 6b and the right end portion 6g of the right side surface portion 6c continue from the front end portion 6d to the rear end portion 6e so as to draw a convex parabola, and the rear ends of the left side surface portion 6b and the right side surface portion 6c. The portion extends from the rear end 6e of the main body 6a and is connected to the left end 6f and the right end 6g.

Referring to FIG. 6C, the bottom surface 6h of the main body portion 6a is warped in a bow shape from the rear end portion 6e to the front end portion 6d in a side view. Since the main body 6a of the horizontal blade 6 is normally supported by two or three points by a movable arm or the like, it is necessary to increase rigidity so as not to bend and to prevent condensation on the horizontal blade 6 or the like. In order to give heat insulation, it has a predetermined thickness. Therefore, the thickness gradually increases along the shape of the bottom surface 6h in a side view from the front end portion 6d to the ridge line 6j, and a relatively flat upper surface 6i continues with some unevenness, and extends from the ridge line 6j to the rear end portion 6e. The thickness decreases rapidly. In the state where the horizontal blades 6 block the air outlet 4, the flat upper surface 6i of the main body 6a is kept horizontal .

  A left side slit 13 and a right side slit 14 are formed in the left side surface part 6b and the right side surface part 6c of the horizontal blade 6, respectively. The left slit 13 is composed of an upper left slit 13a and a lower left slit 13b, and the right slit 14 is composed of an upper right slit 14a and a lower right slit 14b. The lower left slit 13b is formed between the slope 6k and the slope 6m. The slope 6k is a slope that reaches the vicinity of the left end of the bottom surface 6h obliquely from the upper surface 6i at the left end of the main body 6a. The slope 6m is formed on the back side of the left horizontal blowing guide plate 15, and extends substantially horizontally from the middle height between the rear end upper part 6b1 and the rear end part 6e toward the vicinity of the front end part 6d in the left side surface part 6b. The lower right slit 14b is formed between the slope 6l and the slope 6n. The inclined surface 6l is an inclined surface that reaches the vicinity of the right end portion of the bottom surface 6h obliquely from the upper surface 6i at the right end portion of the main body portion 6a. The slope 6n is formed on the back side of the left horizontal blowing guide plate 15, and is located in the vicinity of the front end 6d from the middle height between the rear end upper part 6b1 and the rear end upper part 6c1 and the rear end 6e in the left side part 6b. It extends substantially horizontally toward

  A left horizontal blowing guide plate 15 is formed between the lower left slit 13b and the upper left slit 13a, and a right horizontal blowing guide plate 16 is formed between the lower right slit 14b and the upper right slit 14a. The left side blowing guide plate 15 and the right side blowing guide plate 16 are formed so as to partially overlap with the slopes 6k and 6l in plan view, but not to overlap most. Further, the left side blowing guide plate 15 and the right side blowing guide plate 16 are inclined downward toward the left side surface portion 6b and the right side surface portion 6c, respectively. Therefore, the conditioned air blown directly from the outlet 4 toward the slopes 6k and 6l is guided obliquely downward toward the left and right ends along the slopes 6k and 6l, and passes through the lower left slit 13b and the lower right slit 14b. The left side surface portion 6b and the right side surface portion 6c are blown out obliquely downward to the left and right. In addition, the conditioned air traveling toward the left and right ends along the main body 6a is closer to the upper surface 6i than the left side blowing guide plate 15 and the right side blowing guide plate 16, and is moved upward by the left side blowing guide plate 15 and the right side blowing guide plate 16. The flow is restricted so as not to escape to the lower left slit 13b and the lower right slit 14b.

  The air heading toward the left side blowing guide plate 15 and the right side blowing guide plate 16 from above is guided diagonally downward toward the left and right ends by the left side blowing guide plate 15 and the right side blowing guide plate 16, and the upper left slit 13a and the upper right slit 14a. , And blown obliquely downward from the left side surface portion 6b and the right side surface portion 6c to the left and right. Auxiliary plates 17 and 18 are formed around the upper part of the upper left slit 13a and the upper right slit 14a to suppress the airflow directed upward from the horizontal blades 6.

  The wind direction device includes an ejection mechanism that drives the horizontal blades 6 in order to adjust the angle when the horizontal blades 6 are opened and closed and opened. The urging mechanism includes three arms 40, 41, 42 arranged in parallel with each other at the longitudinal center of the casing body 2 and on the left and right sides thereof (see FIG. 10). The three arms 40, 41, 42 are moved (protruded) so as to extend obliquely downward toward the front by a rack and pinion mechanism (not shown), or moved in the opposite direction to be stored. Or Since these arms 40, 41, and 42 are driven by a rack and pinion mechanism so that the amount of movement is the same, the movement of the horizontal blades 6 supported by the arms 40, 41, and 42 becomes parallel movement. The arms 40, 41, and 42 are attached to the horizontal blade 6 via a drive shaft (not shown) on the same axis, and the horizontal blade 6 can be rotated around the axis of the drive shaft. The wind direction device combines the parallel movement and the rotational movement of the horizontal blade 6 by adjusting the amount of projection of the arms 40, 41 and 42 by the rack and pinion mechanism and adjusting the rotation angle of the horizontal blade 6 by the drive shaft. The horizontal blades 6 can take various postures. For example, the horizontal blade | wing 6 can take the attitude | position in which the upper surface 6i of the main-body part 6a of the flat horizontal blade | wing 6 becomes horizontal.

  As described above, the air direction device of the air conditioner includes the horizontal blades 6 and the vertical blades 9, the ejection mechanism for driving them, and the vertical blade driving unit. The vertical blade driving unit has the above-described vertical blade connecting rod 10 in order to drive the vertical blade 9. Control of the ejection mechanism and the vertical blade driving unit will be described later.

  By adjusting the blowing direction of the horizontal blade 6 and the vertical blade 9 and adjusting the wind speed of the cross flow fan 7, appropriate air conditioning corresponding to the indoor form and the indoor situation can be performed. In order to control the horizontal blades 6, the vertical blades 9, and the cross flow fan 7, a control unit 20 as shown in FIG. 8 is provided. The control unit 20 includes an indoor control unit 21 for controlling each device of the indoor unit 1 and an outdoor control unit 22 for controlling each device of the outdoor unit, and the indoor control unit 21 and the outdoor control unit. 22 is connected by a signal line 23.

  The outdoor control unit 22 is connected to a compressor 24, an outdoor electric expansion valve 25, a four-way switching valve 26, an outdoor fan 27, a plurality of pressure sensors 28, a plurality of temperature sensors 29, and the like. The outdoor control unit 22 controls the refrigerant circulation amount of the refrigerant circuit by controlling the rotational speed of the compressor 24, for example, and controls the pressure of the refrigerant flowing through the refrigerant circuit by controlling the opening degree of the outdoor electric expansion valve 25. To do. The outdoor control unit 22 switches the circulation path of the refrigerant flowing in the refrigeration circuit by switching the four-way switching valve 26 to control operation switching such as switching between heating operation and cooling operation. The outdoor control unit 22 controls the heat exchange efficiency in the outdoor heat exchanger by controlling the rotational speed of the outdoor fan 27. Therefore, the outdoor control unit 22 uses the temperature and pressure of each part detected by a plurality of temperature sensors 29 and pressure sensors 28 installed in the refrigerant circuit and each device for judgment for control.

  On the other hand, the indoor control unit 21 is connected to a transmission / reception unit 30, an ejection mechanism 31, a vertical blade drive unit 32, a crossflow fan motor 33, a plurality of temperature sensors 34, a display unit 35, and the like. The indoor control unit 21 transmits and receives data between the user's remote controller and the transmission / reception unit 30 for control. The indoor control unit 21 controls the urging mechanism 31, the vertical blade drive unit 32, and the crossflow fan motor 33 according to the indoor state and the user's settings, thereby controlling the angles and fluctuations of the horizontal blades 6 and the vertical blades 9. The state of movement and the rotational speed of the motor 33 for the cross flow fan can be adjusted to change the blowing direction and the strength of blowing the conditioned air. The indoor control unit 21 uses state information such as the temperature of each part detected by a plurality of temperature sensors 29 or the like installed in the refrigerant circuit or each device for judgment for control. In addition, the indoor control unit 21 notifies the user of the setting state and environment of the indoor unit 1 via the display unit 35.

<Operation of wind direction device>
When the indoor unit 1 is stopped, the horizontal blade 6 is normally closed as described with reference to FIGS. This prevents dust or pollen from accumulating on the horizontal blade 6 when the indoor unit 1 is stopped. As shown in FIGS. 6 and 7, the horizontal blade 6 is formed with a left side slit 13 and a right side slit 14. However, since the left side surface portion 6b and the right side surface portion 6c of the horizontal blade 6 are curved, the left side slit 13 and the right side slit 14 are not the left side surface 1b and the right side surface 1c of the indoor unit 1, but rather the bottom surface of the indoor unit 1. 1e. Further, since the slopes 6k, 6l, the left side blowing guide plate 15 and the right side blowing guide plate 16 are inclined obliquely downward, the horizontal blades 6 are closed so that dust, pollen and the like are not easily accumulated.

(Blow left and right)
FIG. 9 is a partially enlarged view showing the state of the indoor unit as viewed from the front side on the lower right. FIG. 9 shows a state in which conditioned air is blown out only in the left-right direction with the horizontal blades 6 closed. Also, in FIGS. 1 to 4 described above, the conditioned air blowing direction in this state is indicated by arrows. At this time, the indoor control unit 21 of the control unit 20 outputs an instruction signal to the ejection mechanism 31 so that the horizontal blades 6 are closed. In order to make it easier to blow right and left, the indoor control unit 21 outputs an instruction signal to the vertical blade drive unit 32 so that the group A of the vertical blades 9 is tilted to the left and the group B is tilted to change the airflow to the right. To do. Accordingly, for example, as shown in FIG. 9, if it is on the right side, conditioned air is blown out from the upper right slit 14 a and the lower right slit 14 b toward the lower right direction D 1, D 2 of the indoor unit 1. For example, since the direction D2 of the conditioned air blown out from the lower right slit 14b is regulated by the angle between the slope 6m and the lower surface of the right side blowing guide plate 16, the direction D2 is set depending on how this angle is formed. can do.

  Here, the case where the right side blowing guide plate 16 is fixed has been described. However, the angle of the lower surface of the right side blowing guide plate 16 can be changed and changed, and in that case, manually or The direction D2 can be automatically changed according to the situation. The direction D1 can also be set by the angle of the upper surface of the right side blowing guide plate 16 as in the direction D2. The strength at which the conditioned air is blown out is adjusted by setting the rotational speed of the cross flow fan 7 to an appropriate value, and an instruction signal for the adjustment is sent from the indoor control unit 21 to the cross flow fan. It is output to the motor 33.

(Blowout during cooling operation)
FIG. 10A shows a front view of the indoor unit during the cooling operation, and FIG. 10B shows a bottom view of the indoor unit during the cooling operation. Further, FIG. 11A shows a side view of the indoor unit during the cooling operation, and FIG. 11B shows a perspective view of the indoor unit during the cooling operation. During the cooling operation, the front end portion 6d of the horizontal blade 6 is lowered from the rear end portion 6e, and the upper surface 6i of the horizontal blade 6 is inclined, for example, about 30 degrees with respect to the horizontal. In order to bring the horizontal blade 6 suspended by the central arm 40 and the left and right arms 41 and 42 into the state shown in FIGS. 10 and 11, the horizontal blade 6 is pushed out by extending the arms 40, 41 and 42. It is necessary to perform the operation and the operation of changing the angle of the horizontal blade 6 with respect to the arm 40 by the drive shaft 43 at the tip of the arm 40. When the conditioned air is blown out from the outlet 4 in a state where the horizontal blades 6 are opened at the angles shown in FIGS. 10 and 11, from between the front end portion 6 d of the horizontal blade 6 and the bottom surface 1 e of the indoor unit 1. A conditioned air flow toward the front is formed. The conditioned air is conveyed toward the wall on the opposite side of the indoor wall to which the indoor unit 1 is attached by this air flow.

  At this time, for example, when the vertical blade 9 is fixed perpendicularly to the longitudinal direction of the casing body 2, conditioned air blown from the outlet 4 is guided to the left slit 13 and the right slit 14 at both left and right ends of the horizontal blade 6. Not. When the vertical blades 9 are fixed substantially vertically as described above, almost all the conditioned air flows straight forward. The direction of the airflow at this time is indicated by an arrow in FIG. In this case, the forward flow is smooth due to the left side surface portion 6b and the right side surface portion 6c. On the other hand, the vertical blade 9 can be adjusted to an angle at which the conditioned air does not reach the left slit 13 and the right slit 14 at both left and right ends while the vertical blade 9 is tilted left and right. In this case, the conditioned air flowing forward by the horizontal blades 6 spreads in a fan shape. The direction of the airflow at this time is indicated by an arrow in FIG. Further, the vertical blade 9 can be tilted to the left and right so that the conditioned air reaches the left slit 13 and the right slit 14 at both left and right ends. In this case, not only the conditioned air flowing forward by the horizontal blades 6 spreads out in a fan shape, but also the conditioned air that has passed through the left slit 13 is transmitted to the left side blowing guide plate 15 and the right side blowing guide plate 16 or the slope 6k, It flows in the left-right direction along 6l. The direction of the airflow at this time is indicated by an arrow in FIG. In this case, the left side blowing guide plate 15 and the right side blowing guide plate 16 and the slopes 6k, 6l are angled with respect to the upper surface 6i of the horizontal blade 6, thereby giving the airflow a slightly rearward direction vector. be able to. With such a setting, the conditioned air can be blown into a zone along the wall just beside the indoor unit 1, which is difficult to guide only with the vertical blades 9 due to the depth of the indoor unit 1. Note that the right side blowing guide plate 16 may be configured to blow rightward without giving an angle.

  Moreover, it can also comprise so that the intensity | strength of the airflow which goes to the left-right direction may be changed by changing the angle of the horizontal blade | wing 6. FIG. For example, the closer the upper surface 6i of the horizontal blade 6 is to a direction perpendicular to the direction of the laminar flow blown out from the blower outlet 4, the weaker the strength toward the front of the airflow is, while moving in the left-right direction. Increases the strength of the airflow.

(Blowout during heating operation)
FIG. 12A shows a front view of the indoor unit during the heating operation, and FIG. 12B shows a bottom view of the indoor unit during the heating operation. FIG. 13A shows a side view of the indoor unit during the heating operation, and FIG. 13B shows a perspective view of the indoor unit during the heating operation. During the heating operation, the rear end portion 6e of the horizontal blade 6 is below the front end portion 6d, and the upper surface 6i of the horizontal blade 6 is substantially vertical. In the state shown in FIGS. 12 and 13, the rear end portion 6 e protrudes forward and the upper surface 6 i faces slightly downward from the state in which the upper surface 6 i is substantially vertical. In order to make the horizontal blade 6 suspended by the central arm 40 and the left and right arms 41, 42 into the state shown in FIGS. 12 and 13, the arms 40, 41, 42 use the horizontal blades as in the above cooling operation. 6 is pushed out, and the horizontal blade 6 is changed to a vertical state by the drive shaft 43 at the tip of the arm 40. When the conditioned air is blown out from the outlet 4 in a state where the horizontal blades 6 are opened at the angles shown in FIGS. 12 and 13, the conditioned air is blocked by the horizontal blades 6 and flows downward.

  At this time, if the vertical blade 9 is fixed perpendicularly to the longitudinal direction of the casing body 2, the conditioned air blown from the outlet 4 is guided to the left slit 13 and the right slit 14 at the left and right ends of the horizontal blade 6. Rather, almost all conditioned air flows straight down. At this time, due to the left side surface portion 6b and the right side surface portion 6c, the downward flow becomes smooth. On the other hand, the vertical blade 9 is tilted to the left and right so that the conditioned air does not reach the left slit 13 and the right slit 14 at both left and right ends, and the conditioned air flowing downward by the horizontal blade 6 can be fan-shaped. it can. The direction of the airflow at this time is indicated by an arrow in FIG. Further, the vertical blade 9 can be tilted to the left and right so that the conditioned air reaches the left slit 13 and the right slit 14 at both left and right ends. In this case, not only the conditioned air flowing forward by the horizontal blades 6 spreads out in a fan shape, but also the conditioned air that has passed through the left slit 13 is transmitted to the left side blowing guide plate 15 and the right side blowing guide plate 16 or the slope 6k, It flows in the left-right direction along 6l. At this time, since the left side blowing guide plate 15 and the right side blowing guide plate 16 and the slopes 6k and 6l have an angle with respect to the upper surface 6i of the horizontal blade 6, it is possible to give the airflow a slightly forward direction vector. it can. Thereby, the conditioned air can be blown out to a zone that is difficult to be guided only by being blocked by the horizontal blades 6 and is slightly forward on the lower side of the left and right sides of the indoor unit 1. The direction of the airflow at this time is shown in FIGS. 12 (a) and 12 (b). In addition, description of the airflow which goes right below in FIG.12 (b) is abbreviate | omitted. During the heating operation, the angle of the horizontal blade 6 can be changed. For example, the closer the upper surface 6i of the horizontal blade 6 is to a direction perpendicular to the direction of the laminar flow blown out from the blower outlet 4, the weaker the strength toward the front of the airflow is, while moving in the left-right direction. Increases the strength of the airflow.

(Blowout in insensitive airflow mode)
In the following description, the conditioned air blowing mode that makes the air flow very weak so that the human body hardly feels the air flow is referred to as an insensitive air flow mode. FIG. 14A shows a front view of the indoor unit in the insensitive airflow mode, and FIG. 14B shows a bottom view of the indoor unit in the insensitive airflow mode. FIG. 15A shows a side view of the indoor unit in the insensitive airflow mode, and FIG. 15B shows a perspective view of the indoor unit in the insensitive airflow mode. In the insensitive airflow mode, the front end portion 6d of the horizontal blade 6 is slightly raised from the rear end portion 6e, and the upper surface 6i of the horizontal blade 6 faces the air outlet 4. That is, the posture of the horizontal blade 6 in the insensitive airflow mode is substantially parallel to the posture in which the horizontal blade 6 closes the outlet 4. To bring the horizontal blade 6 suspended by the central arm 40 and the left and right arms 41 and 42 into the state shown in FIGS. 14 and 15, the horizontal blade 6 is pushed out by a predetermined amount by the arms 40, 41 and 42. Then, the rear end 6e of the horizontal blade 6 is changed to a slightly lowered state by the drive shaft 43 (see FIG. 11B) at the tip of the arm 40. That is, the indoor unit 1 can open the blower outlet 4 in a state where the horizontal blade 6 is pushed out and the horizontal blade 6 is orthogonal to the airflow blown out from the blower outlet 4. If the horizontal blades 6 are kept at an angle orthogonal to the air flow blown from the outlet 4, the conditioned air strikes the horizontal blades 6 and flows not only in the front and left and right directions but also in the rear, that is, can be blown out in four directions. It becomes a state.

  The state shown in FIGS. 14 and 15 is a state in which the tip end portion 6d is slightly lower than the state in which the upper surface 6i is perpendicular to the blowing direction of the laminar flow blown from the blower outlet 4. In this state, the airflow is weakened by hitting the horizontal blades 6, but it can be said that the flow of the conditioned air to the rear is hardly present or is extremely weak. In FIG. 14 and FIG. 15, the extremely weak airflow generated at the rear is indicated by an arrow smaller than the arrows directed to the front and left and right directions. At this time, the number of rotations of the cross flow fan 7 is also reduced, and the amount of air blown from the outlet 4 is reduced. Thereby, in addition to the air volume of the conditioned air being blown off being reduced and the wind speed being weakened, the conditioned air is applied to the horizontal blades 6 to reduce the wind speed, thereby making it difficult for a person to feel the air flow. In this state, the flow of conditioned air can also be adjusted by adjusting the amount of protrusion of the arms 40, 41, and 42 to change the distance between the periphery of the outlet 4 and the horizontal blade 6.

  In this case, the airflow flowing to the left and right by the vertical blades 9 can be controlled as in the cooling operation and the heating operation. Since the conditioned air that has flowed to the left and right flows along the left side blowing guide plate 15 and the right side blowing guide plate 16, it is blown to the left and right at a desired angle defined by the left side blowing guide plate 15 and the right side blowing guide plate 16.

Second Embodiment
The outline of the air conditioner according to the second embodiment is the same as that of the air conditioner of the first embodiment described above. The indoor unit of the air conditioner according to the second embodiment includes a wind direction device for the air conditioner that is different from the indoor unit of the first embodiment. The difference between the wind direction device of the second embodiment and the wind direction device of the first embodiment is the configuration of the ejection mechanism. FIG. 16 is a perspective view of the indoor unit 1A according to the second embodiment as viewed obliquely from the lower right. The decorative panel 5 is the same in the first embodiment and the second embodiment, and the air outlet 4 has the opening 12a of the bottom surface 1e and the openings 12b and 12c provided on the left and right sides thereof. Therefore, the horizontal blade 6A has a main body portion 6Aa, a left side surface portion 6Ab, and a right side surface portion 6Ac.

<Configuration of wind direction device>
As shown in FIG. 16, the urging mechanism for driving the horizontal blade 6A includes a left support arm 51 and a right support arm 52 for moving the horizontal blade 6A in parallel while supporting the horizontal blade 6A. The left support arm 51 and the right support arm 52 are moved (protruded) so as to extend obliquely downward toward the front by a rack and pinion mechanism (not shown), or moved and stored in the opposite direction. To do. The left support arm 51 and the right support arm 52 are connected to the horizontal blade 6A by a ball joint (not shown) instead of being pivotally supported by the connecting portion 51a connected to the horizontal blade 6A. In addition to rotating the horizontal blade 6A forward and backward in a state in which the horizontal blade 6 is supported, the horizontal blade 6A can be tilted to the left and right.

  The ejection mechanism includes a rotation mechanism including a rotation arm 50a and a swing arm 50b. One end of the turning arm 50a connected to the casing body 2 is pivotally supported by a drive shaft (not shown), and can turn around the drive shaft. The other end side of the rotation arm 50a and one end side of the swing arm 50b are connected by a movable shaft 50c, and the swing arm 50b can swing around the movable shaft 50c. Further, the other end side of the swing arm 50b is supported by the horizontal blade 6A by the connecting portion 50d of the ball joint, and the swing arm 50b can swing around the connecting portion 50d. The position where the horizontal blade 6A is connected by the connecting part 50d is that the axis connecting the connecting parts 51a, 52a connecting the left support arm 51 and the right support arm 52 is in the vicinity of the front end part 6Ad. The vicinity of the end 6Ae. Since the axis connecting the connecting portions 51a and 52a of the left support arm 51 and the right support arm 52 and the position of the connecting portion 50d of the swing arm 50b are displaced in the front-rear direction of the horizontal blade 6A, the rotating arm 50a is rotated. Accordingly, the horizontal blade 6A can be rotated. Further, since the swing arm 50b swings, the distance between the drive shaft on one end of the swing arm 50a and the connecting portion 50d of the swing arm 50b can be changed. On the other hand, the horizontal blade 6A can be moved in parallel by following the rotation of the rotation arm 50a. Thereby, the horizontal blade | wing 6A can take the attitude | position in which the flat upper surface 6Ai of main-body part 6Aa becomes horizontal, for example.

  As described above, the air direction device of the air conditioner includes the horizontal blades 6A and the vertical blades 9, the ejection mechanism for driving them, and the vertical blade driving unit. Control of the ejection mechanism and the vertical blade driving unit will be described later. The vertical blade driving unit has the above-described vertical blade connecting rod 10 in order to drive the vertical blade 9. By adjusting the blowing direction of the horizontal blades 6A and the vertical blades 9 and adjusting the wind speed of the cross flow fan 7, the air flow of conditioned air for appropriate air conditioning corresponding to the indoor form and the indoor situation is generated. To do. In order to control the horizontal blades 6A, the vertical blades 9 and the cross flow fan 7, a control unit 20A as shown in FIG. 17 is provided. The control unit 20A includes an indoor control unit 21A for controlling each device of the indoor unit 1 and an outdoor control unit 22 for controlling each device of the outdoor unit. The indoor control unit 21A and the outdoor control unit 22 is connected by a signal line 23. Since the difference between the control unit 20 of the first embodiment and the control unit 20A of the second embodiment is only the difference between the indoor control unit 21 and the indoor control unit 21A, the indoor control unit 21A will be described below, and the outdoor control unit Description of 22 is omitted. In addition, the relationship between the transmission / reception unit 30, the crossflow fan motor 33, the temperature sensor 29, the display unit 35, and the like and the indoor control unit 21A is the same as that in the indoor control unit 21, and thus the description thereof is omitted.

  The indoor control unit 21A is connected to a transmission / reception unit 30, an ejection mechanism 31A, a vertical blade driving unit 32, a crossflow fan motor 33, a temperature sensor 34, a display unit 35, and the like. The push-out mechanism 31A controlled by the indoor control unit 21A includes a left support arm drive unit 36 and a right support arm drive unit 37 in order to tilt the horizontal blade 6A to the left or right. The indoor control unit 21A can drive the left support arm drive unit 36 and the right support arm drive unit 37 independently. When moving the horizontal blade 6A in parallel, the indoor control unit 21A controls the movement amount of the left support arm 51 and the movement amount of the right support arm 52 to be the same, and tilts the horizontal blade 6A to the left or right. In some cases, the movement amount of the left support arm 51 and the movement amount of the right support arm 52 are controlled to be different.

  In order to release the horizontal blade 6A from the state where the blower 4 is closed and to make the horizontal blade 6A into a desired state, the indoor control unit 21A first uses the left support arm drive unit 36 and the right support arm drive unit 37. The left support arm 51 and the right support arm 52 are moved to push out the horizontal blade 6A. As a result, the air outlet 4 blocked by the horizontal blade 6A is opened. At this time, the rotation mechanism drive unit 38 follows the horizontal blade 6A so as to move in parallel, and rotates the rotation arm 50a. Move.

  Next, while the left support arm 51 and the right support arm 52 are fixed, the rotation mechanism drive unit 38 rotates the rotation arm 50a to connect the connecting portion 51a of the left support arm 51 and the right support arm 52. The horizontal blade 6A is rotated around an axis connecting the connecting portion 52a. The horizontal blade 6A can be moved to a desired state by the two-step operation of the parallel movement and the rotational movement as described above.

  Note that the indoor control unit 21A controls the horizontal blade 6A to move to a desired state in one step by performing the two-step operation as described above in parallel and rotating while moving in parallel. You can also

<Operation of wind direction device>
In the operation of the wind direction device according to the second embodiment, when conditioned air is blown out from the outlet 4 with the horizontal blade 6A being horizontal, the following four operations are performed as in the first embodiment. Can be made. That is, about the right-and-left blowing in the state which closed the blower outlet 4 with the horizontal blade | wing 6A, or the blowing in the cooling operation when the horizontal blade 6A is in the horizontal state, the blowing in the heating operation, and the blowing in the insensitive airflow mode The wind direction device of the second embodiment is the same as the wind direction device of the first embodiment.

(Blowout in insensitive airflow mode)
FIG. 18 shows a front state when the horizontal blades are tilted in the insensitive airflow mode, and FIG. 19 shows a state seen from the diagonal right side. 18 and 19 show a state where the left side of the horizontal blade 6A is lowered by extending the left support arm 51 longer than the right support arm 52. FIG. Further, since the insensitive airflow mode is in effect, the front end 6Ad of the horizontal blade 6A is slightly raised from the rear end 6Ae, and the upper surface of the horizontal blade 6A faces the air outlet 4. In other words, the posture of the horizontal blade 6A in the insensitive airflow mode is substantially the same as the posture in which the horizontal blade 6A closes the outlet 4 when the left support arm 51 and the right support arm 52 are extended to the same length. It is parallel, and when the left support arm 51 is extended long, the left side is further lowered from that state.

  When the vertical blade 9 is tilted to the left with respect to the longitudinal direction of the casing body 2 in a state where the left side of the horizontal blade 6A is lowered as described above, the air is blown out from the outlet 4 into the left slit 13 at the left end of the horizontal blade 6A. The conditioned air can be guided. At this time, since the horizontal blade 6A is inclined to the left, it is easy to guide to the left. Further, since the horizontal blade 6A is tilted to the left, the angle of the left side blowing guide plate 15 of the left slit 13 is further tilted downward, so that conditioned air flows in a zone closer to the left side surface 1b of the casing body 2. be able to.

  On the other hand, when the vertical blade 9 is tilted to the right with respect to the longitudinal direction of the casing body 2 while the left side of the horizontal blade 6A is lowered, the harmony blown from the outlet 4 to the right slit 14 at the right end of the horizontal blade 6A. Air can be guided. At this time, since the horizontal blade 6A is tilted to the left, the airflow of the conditioned air is further weakened because the airflow is returned along the horizontal blade 6A when guided to the right side. It becomes easy. Further, since the horizontal blade 6A is inclined to the left, the angle at which the right side blowing guide plate 16 of the right slit 14 is inclined downward is reduced, so that conditioned air can easily flow through a zone far from the right side surface 1c of the casing body 2.

  Even during the cooling operation, by tilting the horizontal blade 6A, the variation of the airflow in the left-right direction can be added in the same manner as the blowing in the insensitive airflow mode. As for the horizontal blade 6A during the cooling operation, the tip end 6Ad is lowered further than the position of the horizontal blade 6A in the insensitive airflow mode, but the appearance is similar, so illustration is omitted. If the vertical blades 9 are tilted so that the horizontal blades 6A are blown toward the inclined side, it becomes easy to blow out a fast air current. Moreover, since the angle of the left side blowing guide plate 15 or the right side blowing guide plate 16 is changed by the inclination of the horizontal blade 6A, the left and right blowing directions can be finely adjusted. On the other hand, if the vertical blades 9 are tilted so as to blow in the direction opposite to the direction in which the horizontal blades 6A are tilted, it is easy to blow a slow air current.

(Blowout during heating operation)
FIG. 20 shows a front state when the horizontal blades are tilted during heating operation, and FIG. 21 shows a state seen obliquely from the right side. 20 and 21 show a state in which the left side of the horizontal blade 6A is lowered by extending the left support arm 51 longer than the right support arm 52. FIG. Moreover, since it is during heating operation, the front end portion 6Ad of the horizontal blade 6A is lower than the rear end portion 6Ae, the rear end portion 6Ae protrudes forward from the vertical state of the horizontal blade 6A, and the upper surface is slightly lower. It is in a state of facing.

  When the vertical blade 9 is tilted to the left with respect to the longitudinal direction of the casing body 2 in a state where the left side of the horizontal blade 6A is lowered as described above, the air is blown out from the outlet 4 into the left slit 13 at the left end of the horizontal blade 6A. The conditioned air can be guided. At this time, since the horizontal blade 6A is inclined to the left, it can be blown out to the left more strongly than when the horizontal blade 6A is horizontal. Further, since the horizontal blade 6 </ b> A is inclined to the left, the conditioned air can easily flow through the left front side of the casing body 2 due to the angle of the left side blowing guide plate 15 of the left side slit 13.

  On the other hand, when the vertical blade 9 is tilted to the right with respect to the longitudinal direction of the casing body 2 while the left side of the horizontal blade 6A is lowered, the harmony blown from the outlet 4 to the right slit 14 at the right end of the horizontal blade 6A. Air can be guided. At this time, since the horizontal blade 6A is tilted to the left, the conditioned air strikes the horizontal blade 6A when guided to the right side, and the air flow is further weakened. Further, since the horizontal blade 6A is inclined to the left, the angle at which the right side blowing guide plate 16 of the right slit 14 is inclined downward is reduced, so that conditioned air can easily flow through a zone far from the right side surface 1c of the casing body 2.

<Modification>
(1) In the first and second embodiments described above, the case where the left slit 13 and the right slit 14 are formed in the horizontal blades 6 and 6A has been described. The blade 6B can also be used. FIG. 22 (a) shows a front view of the horizontal blade, and FIG. 22 (b) shows a bottom view of the horizontal blade. Similarly to the horizontal blades 6 and 6A described above, the horizontal blade 6B also includes a main body portion 6Ba, a left side surface portion 6Bb, and a right side surface portion 6Bc. FIG. 23 shows an enlarged view of the inside of the right side surface portion 6Bc, and the side end portion 6Bg is higher than the upper surface 6Bi. Thus, it becomes easy to form the right end portion 6Bg high in the right side surface portion 6Bc of the horizontal blade 6B, and the same applies to the left side surface portion 6Bb.

  The left side surface portion 6Bb and the right side surface portion 6Bc formed higher than the upper surface 6Bi restrict the flow of conditioned air in the left-right direction. For example, when the vertical blade 9 is directed straight forward, the front surface of the horizontal blade 6B It becomes easy to form an air current of flowing conditioned air. On the other hand, when the vertical blades 9 are tilted in the left-right direction to guide the conditioned air in the left-right direction, an air flow of conditioned air slightly upward from the horizontal can be generated.

  When the horizontal blade 6B is combined with the wind direction device according to the second embodiment, the horizontal blade 6B is tilted to either the left or right as in the second embodiment, so that the conditioned air by the vertical blade 9 is moved in the left-right direction. The intensity of the airflow can be finely adjusted. For the conditioned air flowing on the left side, the angle of the air flow of the conditioned air guided slightly upward from the horizontal by the left side surface portion 6Bb can be adjusted by the inclination of the horizontal blade 6B. Similarly, for the conditioned air flowing on the right side, the angle of the air flow of the conditioned air guided slightly upward from the horizontal by the right side surface portion 6Bc can be adjusted by the inclination of the horizontal blade 6B.

  (2) In the first embodiment, the second embodiment, and the modified example (1), the left side surface portion 6b, 6Ab, 6Bb and the right side surface portion 6c, 6Ac, 6Bc are formed with the left side slit 13 and the right side slit 14. The case where it is formed or not formed has been described. That is, in the horizontal blades 6, 6A, 6B, the states of the left side surfaces 6b, 6Ab, 6Bb and the right side surfaces 6c, 6Ac, 6Bc are fixed, and are not changed midway.

  However, a shutter that slides on the left slit 13 and the right slit 14 is provided, and is manually opened and closed, so that the state of the first embodiment and the second embodiment and the modification (1) is switched. You can also Further, the left slit 13 and the right slit 14 can be automatically opened and closed instead of manually.

  Furthermore, you may comprise so that the magnitude | size of the opening of the left side slit 13 and the right side slit 14 may be adjusted with a shutter. Thereby, it is possible to perform finer air conditioning according to the indoor state and environment.

  (3) In the first and second embodiments and the modified examples (1) and (2), as shown in FIG. 5, the left opening 12b and the right opening 12c of the outlet 4 are shown. Explained the case where a member that guides the airflow is not provided but the opening is simply formed.

  However, the guide shown in FIG. 24 can also be provided in the outlet passage 8 following the outlet 4. FIG. 24A and FIG. 24B are both perspective views showing a state in which the indoor unit 1B is viewed from the lower right side. FIG. 24 (a) looks up from the position moved further to the right side than FIG. 24 (b). The guide 60 provided in the opening 12c on the right side is a substantially plate-like member arranged horizontally, and guides conditioned air in the longitudinal direction of the air outlet 4 (longitudinal direction of the horizontal blades 6, 6A, 6B). To do. Therefore, a slit-like gap 61 is formed between the casing body 2 and the guide 60. 24 (a) and 24 (b) only show the right guide 60, the left side is provided with a guide for blowing to the left side symmetrically with the right side. Since the left guide has the same function as the right guide 60, the description of the left guide is omitted in the following description.

  When the right slit 14 is formed as in the horizontal blades 6 and 6A of the first embodiment and the second embodiment, the horizontal blade 6 is formed by inclining the vertical blade 9 and blowing conditioned air to the right. , 6A is closed, and conditioned air is guided from the guide 60 to the right slit 14. Therefore, the cooperation of the guide 60 and the right slit 14 facilitates the blowing of conditioned air in the right direction.

  When the horizontal blades 6 and 6A having the right slit 14 are slightly opened until the gap 61 of the guide 60 is not blocked by the horizontal blades 6 and 6A, the conditioned air is discharged horizontally from the gap 61 of the guide 60 to the right side. Simultaneously with the blowout, conditioned air can be blown out from the right slit 14 in the right direction. Therefore, more conditioned air can be blown rightward by the cooperation of the guide 60 and the horizontal blades 6 and 6A.

  In the case of the above modification (1), when the horizontal blade 6B is slightly opened until the gap 61 of the guide 60 is not blocked by the horizontal blade 6B, the gap 61 of the guide 60 is horizontally moved to the right side. Harmonic air can be blown out. Therefore, the conditioned air can be strongly blown out in the right direction by the guide 60 in spite of the right side surface portion 6Bc of the horizontal blade 6B. In addition, as described in the modification (2), the slit can be configured to be openable / closable so as to have both the functions with and without the slit, and the degree of opening / closing is switched. You can also.

  Moreover, the horizontal blade | wing 6B can be inclined using the wind direction apparatus of the said 2nd Embodiment. In this case, by tilting, for example, by covering the left guide with the left side surface portion 6Bb, it is possible to blow out from the right guide 60 or blow out only from the right guide 60. In addition, for example, by combining the horizontal blade 6A and the guide 60 of the wind direction device of the second embodiment, variations in the flow of conditioned air in the right direction can be further increased.

  (4) In the first embodiment, the second embodiment, and the modifications (1) and (2), as shown in FIG. 5, the left opening 12 b and the right opening 12 c of the outlet 4. Is not formed with such a large opening as to cut out the left side surface 1b and the right side surface 1c of the decorative panel 5. Therefore, the design of the decorative panel 5 is clearly refined and has a beautiful appearance as the indoor units 1 and 1A. However, although the appearance of the indoor units 1 and 1A is sacrificed, the right side portion 6Cc and the left side portion (not shown) are enlarged and the left and right openings are enlarged as in the horizontal blade 6C shown in FIG. You can also. FIG. 25A shows a state where the horizontal blade 6C is closed, and FIG. 25B shows a state where the horizontal blade 6C is opened. The right side surface 1c of the indoor unit 1C shown in FIG. 25 is partially cut away, and the right opening 12c constituting the outlet 4 is large. Although not shown in FIG. 25, the horizontal blade 6C includes a main body portion and a left side surface portion as in the first embodiment and the second embodiment.

<Features>
(A)
The horizontal blades 6, 6 </ b> A, 6 </ b> B, 6 </ b> C provided in the indoor units 1, 1 </ b> A, 1 </ b> B, 1 </ b> C can open and close the air outlet 4 and change the direction of the conditioned air blown from the air outlet 4 up and down. it can. The air outlets 4 that the horizontal blades 6, 6A, 6B, 6C open and close are the opening 12b (left side opening) of the left side 1b of the indoor units 1, 1A, 1B, 1C and the openings of the right side 1c, 1c. It consists of a part 12c (right side opening) and an opening 12a (front opening) between these openings 12b and 12c. In the above embodiment, the case where these three openings 12a, 12b, and 12c are connected and integrally opened is described. However, the openings 12a, 12b, and 12c are separated by, for example, a crosspiece or the like. It may be. In that case, a member that separates the openings 12a, 12b, and 12c, such as a crosspiece, may be configured to be covered with the openings 12a, 12b, and 12c by the closed horizontal blades 6, 6A, 6B, and 6C. It is preferable for constructing a clean and beautiful appearance. When connecting the decorative panel 5 with such a crosspiece or the like, the strength of the decorative panel 5 can be improved by the crosspiece or the like, and problems such as generation of noise due to vibration of the decorative panel 5 can be prevented. 25 shows the opening 12c that is large enough to cut out the right side surface 1c, but the left and right openings 12b and 12c do not necessarily have to be formed by cutting out the side surface of the indoor unit. In the first and second embodiments described above, the bottom surfaces 1e and 1e are formed by being recessed.

  The horizontal blades 6, 6A, 6B, 6C have main body portions 6a, 6Aa, 6Ba, left side portions 6b, 6Ab, 6Bb and right side portions 6c, 6Ac, 6Bc, 6Cc. When the air outlet 4 is closed, the body portions 6a, 6Aa, 6Ba cover the opening portion 12a, the left side surface portions 6b, 6Ab, 6Bb cover the opening portion 12b, and the right side surface portions 6c, 6Ac, 6Bc, 6Cc cover the opening portion 12c. cover. Main body portions 6a, 6Aa, 6Ba are exclusively used for changing the wind direction in the vertical direction. When conditioned air hits the main body portions 6a, 6Aa, 6Ba of the horizontal blades 6, 6A, 6B, 6C, the left side surface portions 6b, 6Ab, 6Bb and the right side surface portion 6c, in the left-right direction of the main body portions 6a, 6Aa, 6Ba, Since 6Ac, 6Bc, and 6Cc are present, it is difficult for the airflow to flow in the left-right direction, and it is easy to guide in the front-rear direction. While the conditioned air can be adjusted in the left-right direction by the vertical blades 9, the left side surfaces 6b, 6Ab, 6Bb and the right side surfaces 6c, 6Ac, 6Bc, 6Cc can be easily blown forward, so that the indoor conditions and environment It becomes easy to generate airflow suitable for the state, and it becomes easy to realize comfortable air conditioning.

  In such horizontal blades 6, 6A, 6B, 6C, the upper surfaces 6i, 6Ai, 6Bi of the main body portions 6a, 6Aa, 6Ba are flat (flat), and these upper surfaces 6i, 6Ai, 6Bi are horizontal. Can take. Therefore, the left side surface portions 6b, 6Ab, 6Bb and the right side surface portions 6c, 6Ac, 6Bc, 6Cc are placed on the left and right body portions 6a, 6Aa, 6Ba in a horizontal posture so that the air outlet 4 can be used during cooling operation. The air flow of the conditioned air blown obliquely downward can be changed in a horizontal direction so that the conditioned air can reach a relatively long distance, and air conditioning of the entire room becomes easy.

  Of these horizontal blades 6, 6A, 6B, 6C, the horizontal blades 6, 6A, 6C have a left side slit 13 formed in the left side surface portions 6b, 6Ab, 6Bb, and a right side slit 14 in the right side surface portions 6c, 6Ac, 6Bc, 6Cc. Is formed. Since the left side surface portions 6b, 6Ab, 6Bb and the right side surface portions 6c, 6Ac, 6Bc, 6Cc are present, the conditioned air is difficult to move in the left-right direction. The conditioned air can be guided in the left-right direction through 13 and the right slit 14. As described above, the horizontal blades 6, 6A, 6C are moved in the left-right direction due to the left slit 13 and the right slit 14 in spite of the left side portions 6b, 6Ab, 6Bb and the right side portions 6c, 6Ac, 6Bc, 6Cc. It is easy to create a harmonious air flow. Since the left slit and the right slit make it easy to create a flow of conditioned air in the left-right direction, it becomes easy to perform air conditioning in a region along the wall to which the indoor unit is attached.

  The horizontal blades 6, 6 </ b> A, 6 </ b> C described above are controlled by the control units 20, 20 </ b> A, and the control units 20, 20 </ b> A can block the air outlet 4 with the horizontal blades 6, 6 </ b> A, 6 </ b> C. And the control parts 20 and 20A can drive the motor 33 for crossflow fans in the state which the horizontal blade | wings 6, 6A, and 6C block | closed the blower outlet 4. FIG. When the crossflow fan motor 33 is driven, the portions other than the left slit 13 and the right slit 14 are closed, so that conditioned air can be blown out only from the left slit 13 and the right slit 14. In addition, since the other portions are blocked, the conditioned air that is blown out concentrates on the left slit 13 and the right slit 14, so that it is possible to blow out strongly.

(B)
In the indoor units 1, 1A, 1B, 1C, the horizontal blades 6, 6A, 6B, 6C cover the air outlet 4, but the horizontal blades 6, 6A, 6B, 6C create a state where the air outlet 4 is not blocked. You can also. That is, it is in a state where there is a gap between the periphery of the horizontal blades 6, 6 </ b> A, 6 </ b> B, 6 </ b> C and the periphery of the outlet 4. Even in such a state, if the gap is narrowed, a close state can be created when the gap is closed. If there is a gap, the conditioned air can be blown out from the gap, and not only the left-right direction but also the conditioned air flow toward the front can be created at the same time. Since the adjustment of the distance between the periphery of the air outlet 4 and the horizontal blades 6, 6A, 6b, 6C is diversified, there is an effect of increasing variations in control such as the wind direction and the wind speed. Thus, creating a state where there is a gap between the periphery of the horizontal blades 6, 6 </ b> A, 6 </ b> B, 6 </ b> C and the periphery of the air outlet 4 is caused by pushing out the horizontal blades 6, 6 </ b> A, 6 </ b> B, 6 </ b> C. Yes. For that purpose, a mechanism such as the ejection mechanism described in the first and second embodiments is required.

  The urging mechanism can guide conditioned air in the four directions of front, rear, left and right by the arms 40, 41, and 42, the left support arm 51, the right support arm 52 and the rotation mechanism described with reference to FIGS. The main body portions 6a, 6Aa, 6Ba, the left side surface portions 6b, 6Ab, 6Bb and the right side surface portions 6c, 6Ac, 6Bc, 6Cc can be pushed into the state. The conditioned air is not blown out forward and backward as much as possible, but the conditioned air can be adjusted to the state where the conditioned air can be guided in the four directions of front, rear, left and right. It is easy to adjust the horizontal blades 6, 6A, 6B, 6C to an angle that creates an easy-to-flow state. Taking the horizontal blade 6 as an example, by making a fine adjustment such as tilting the tip 6d slightly as shown in FIGS. Air conditioning can be performed in a quiet state where it is difficult for a person to feel the flow. In a situation close to a desired air-conditioning state set by a remote controller or the like, air-conditioning can be performed in a highly quiet state, and comfort of air-conditioning can be improved.

  As described with reference to FIGS. 16 to 21 for the indoor unit 1A according to the second embodiment, the push-out mechanism of the second embodiment can tilt the main body 6Aa to the left or right. In addition to causing the vertical blade 9 to blow out conditioned air strongly to the left, right or both sides, the direction of the reaction that the conditioned air receives from the main body portion 6Aa is determined by the inclination of the main body portion 6Aa. When tilting the part 6Aa, the force blown out increases. Conversely, if the main body 6Aa is tilted in the direction opposite to the blowing direction determined by the vertical blades 9, the force with which the conditioned air is blown out is weakened. For example, if the main body 6Aa is tilted to the left so that the left is lowered when the conditioned air is blown to the right by the vertical blades 9, the air flow of the conditioned air blown toward the right becomes weak. In this way, by configuring the main body 6Aa to be tilted, it is possible to finely adjust the airflow of conditioned air that blows to the left and right, and to increase the variation of the airflow, so that air conditioning that matches the indoor situation is performed. It becomes easy.

(C)
Conditioned air can be guided in the horizontal direction of the horizontal blades 6, 6 </ b> A, 6 </ b> B, 6 </ b> C by the right guide 60 shown in FIG. 24 and the left guide not shown. Since the right side guide 60 and the left side guide are in the blowout passage 8 (space covered by the horizontal blades) that is closed when the horizontal blades 6, 6A, 6B, 6C are closed, when the operation is stopped, etc. Since it does not appear in the appearance, it is easy to design for a refined appearance.

  In the horizontal blades 6, 6 </ b> A, 6 </ b> C, unlike the case where the right guide 60 and the left guide are not provided by cooperation with the right guide 60 and the left guide, It is possible to efficiently perform the blowing in the left-right direction. When the horizontal blades 6, 6 </ b> A, 6 </ b> C are closed, a conditioned air flow path guided from the right guide 60 to the right slit 14 can be formed, and a conditioned air flow path guided from the left guide to the left slit 13 is formed. it can. When the horizontal blades 6, 6 </ b> A, 6 </ b> B, 6 </ b> C are opened, they are formed by the right-side guide 60 and the left-side guide together with the conditioned air flow guided by the horizontal blades 6, 6 </ b> A, 6 </ b> B, 6 </ b> C. Harmonized air is blown out to the left and right by the airflow. Thereby, compared with the case where the right side guide 60 and the left side guide are not provided, it becomes easier to blow out the conditioned air in the left-right direction.
