Description

  The present invention relates to an indoor unit of an air conditioner, and more particularly to an indoor unit of an air conditioner that performs indoor air conditioning by blowing conditioned air into the room.

  When the indoor unit of the air conditioner is, for example, a wall-mounted type, an indoor side heat exchanger is provided in the main body casing, and indoor air is sucked into the main body casing by a blower fan such as a crossflow fan, and then passed through the indoor side heat exchanger. The conditioned air is blown out from the outlet mainly outside the main casing. In order to control the wind direction of the conditioned air blown from the air outlet, a vertical blade for adjusting the wind direction in the left-right direction and a vertical wind direction adjusting blade for adjusting the wind direction in the vertical direction are provided. The outlet of a conventional wall-mounted indoor unit is generally provided on the front or bottom of the indoor unit, and is covered with vertical airflow direction adjustment blades when the indoor unit is stopped, and up and down by vertical airflow direction adjustment blades when the indoor unit is in operation. The wind direction is adjusted. Therefore, the vertical airflow direction adjusting blade is shorter than the length of the air outlet, that is, the length in the longitudinal direction of the main body casing.

  When air outlets are provided on the front surface of the indoor unit or the bottom surface of the indoor unit as described above, because of the depth of the indoor unit, if the conditioned air is blown in the left-right direction using only the vertical blades, the wall-mounted indoor unit It becomes difficult to send conditioned air to a place near the wall where the is attached. Since the wind direction of the conditioned air blown out from the air outlet has a predetermined angle with respect to the wall surface, this tendency becomes more prominent as the distance from the indoor unit becomes longer.

The electrical component box of the indoor unit 2 and the electrical component box of the outdoor unit 3 are connected by a transmission line passing through the collective connection pipe 4.

<Overview of indoor unit configuration>
As shown in FIG. 1, the indoor unit 2 has an air outlet 7 formed on the bottom surface 2 e of the casing body 6. FIG. 2 is a front view of the indoor unit of the air conditioner according to the embodiment of the present invention. As shown in FIG. 2, the indoor unit 2 includes a suction port 8 for sucking indoor air in the top surface 2 d of the casing body 6 in order to blow out conditioned air from the blowout port 7.

  FIG. 3 is a right side view of the indoor unit. As shown in FIG. 3, a cross flow fan 9 is provided inside the casing body 6 of the indoor unit 2 near the back side of the substantially center of the casing body 6 in a side view. In the front view, as shown in FIG. 2, the cross flow fan 9 has the same length as the suction port 8 and is long and horizontally along the longitudinal direction DrL of the indoor unit 2 (casing body 6). Has been placed.

  In addition, an inverted V-shaped indoor heat exchanger (not shown) is disposed on the upstream side of the cross flow fan 9 in the casing body 6 in a side view, Air conditioning is performed by passing room air through the heat exchanger. Thus, in order to perform indoor air conditioning efficiently by sucking indoor air and blowing out conditioned air by the crossflow fan 9 extending long in the longitudinal direction of the casing main body 6, the indoor heat exchanger is also provided in the casing main body 6. It is formed in a shape that extends long in the longitudinal direction, and is disposed between the suction port 8 and the blower port 7 that extend long. 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 cross flow fan 9.

  As shown in FIG. 1, FIG. 2 and FIG. 3, the indoor unit 2 includes five casings 6 excluding the front surface 2a, left side surface 2b, right side surface 2c, top surface 2d and bottom surface 2e, that is, back surface 2f. The surface is covered with the decorative panel 6a. Note that the direction connecting the left side surface 2b and the right side surface 2c of the indoor unit 2, that is, the direction along the longitudinal direction DrL of the indoor unit 2 (air outlet 7) may be referred to as the left-right direction. The left hand in the view is to the left. Further, the direction from the back surface 2f of the indoor unit 2 to the front surface 2a (front surface) is referred to as the front, and the direction from the top surface 2d to the bottom surface 2e is referred to as the downward direction.

  FIG. 1 shows a state in which the horizontal blade 11 provided at the outlet 7 is open, and FIGS. 2 and 3 show a state in which the horizontal blade 11 is closed. In the indoor unit 2, the horizontal blade 11 is closed and the air outlet 7 is closed when the operation is stopped, and the horizontal blade 11 is opened and the air outlet 7 is opened during the operation. In the following description, the expression that the horizontal blades 11 block the air outlet 7 is used to express the state in which there is no gap for blowing out conditioned air between the air outlets 7 and the horizontal blades 11. The expression “covering” is used as an expression that allows a case where there is a gap for blowing out conditioned air with or without a focus on the operation of closing the horizontal blade 11.

  In the indoor unit 2 shown in FIG. 1, indoor air is not sucked from the front surface 2 a, and the indoor unit 2 sucks indoor air exclusively from the suction port 8 of the top surface 2 d of the casing body 6. Therefore, the circulation of the indoor air inside the indoor unit 2 is performed from the top surface 2d side of the indoor unit 2 toward the bottom surface 2e side of the indoor unit 2.

<Blowout passage>
As shown in FIGS. 2 and 3, the indoor unit 2 is provided with a blower passage 10 having a diffuser structure that extends from the cross flow fan 9 to the blower outlet 7. The outlet passage 10 includes a left side wall 10a, a right side wall 10b, a rear guide surface 10c, and a front guide surface 10d. The rear guide surface 10c of the blow-out passage 10 has a smooth curve having a center of curvature on the side of the cross flow fan 9 in a side view, and the radius of curvature increases toward the lower side. The distance between the rear guide surface 10 c and the front guide surface 10 d increases as the distance from the air outlet 7 increases, and increases as the opening of the air outlet passage 10 approaches the air outlet 7. Further, since the cross flow fan 9 is rotated clockwise as viewed from the right side and its central axis is arranged toward the rear surface 2f, the blowout passage 10 is located on the front side of the bottom surface 2e. It is formed obliquely toward Therefore, the conditioned air from the outlet passage 10 toward the outlet 7 has a directional vector directed downward and a directional vector directed forward, resulting in a laminar flow with less turbulence.

<Adjustment of airflow by horizontal and vertical blades>
As shown in FIG. 1, a horizontal blade 11 is provided in front of the air outlet 7. As shown in FIG. 4, a plurality of vertical blades 12 are movably attached to the outlet passage 10. The wind direction device is configured to include these horizontal blades 11 and vertical blades 12, and further includes a drive mechanism described later for driving the horizontal blades 11 and the vertical blades 12. And operation | movement of a drive mechanism is controlled by the control part mentioned later. Under the control of the control unit, the horizontal blades 11 and the vertical blades 12 take various postures to generate a wide variety of conditioned air.

  The indoor unit 2 can adjust the wind direction in the vertical direction of the indoor unit 2 by the horizontal blades 11. Further, the surfaces 12 a of the plurality of vertical blades 12 swing left and right about a state perpendicular to the longitudinal direction of the casing body 6. The surfaces 12a of the vertical blades 12 adjust the blowing direction of the conditioned air in the left-right direction by swinging or stopping at an arbitrary angle after swinging.

  FIG. 5, FIG. 6, FIG. 7 and FIG. 8 show four different states of the horizontal blade 11. FIG. As will be described later, the vertical blade 12 closest to the left side wall 10a and the right side wall 10b of the outlet passage 10 moves so as to protrude from the outlet 7. If the horizontal blade 11 changes only the angle in the blowout passage 10 or the vicinity of the blowout port 7, the protruding vertical blade 12 collides with the horizontal blade and cannot be operated properly. Therefore, the horizontal blades 11 are configured to move so as to push forward when they are released from the state where the air outlet 7 is closed. The horizontal blade 11 moves to become the four states shown in FIGS. 5, 6, 7, and 8, but also stops in the middle of the movement, and is in the middle of transition to these four states. The state posture can also be maintained.

  The state shown in FIG. 5 is a state in which the horizontal blade 11 is closed and the air outlet 7 is blocked by the horizontal blade 11. The state shown in FIGS. 6, 7, and 8 is a state in which the horizontal blade 11 is open and the air outlet 7 is open. In the state shown in FIGS. 6, 7, and 8, the posture of the horizontal blade 11 is Are different.

  In the state shown in FIG. 6, the horizontal blade 11 protrudes, the front end portion 11 a of the horizontal blade 11 rises above the rear end portion 11 b, and the horizontal blade 11 is substantially parallel to the air outlet 7. In the state shown in FIG. 7, the horizontal blade 11 protrudes, the front end portion 11 a of the horizontal blade 11 is lowered from the rear end portion 11 b, and the horizontal blade 11 is greatly opened from the front end portion 11 a toward the front. In the state shown in FIG. 8, the horizontal blade 11 protrudes, the front end portion 11 a of the horizontal blade 11 rises from the rear end portion 11 b, the horizontal blade 11 stands substantially vertically, and lowers from the rear end portion 11 b. It is in the state which opened greatly toward.

  The horizontal blade drive mechanism includes an intermediate support arm 40, a left support arm 41, and a right support arm 42 so that the horizontal blade 11 takes the posture shown in FIGS. 6, 7, and 8. The intermediate support arm 40 of the horizontal blade driving mechanism includes a rotating arm 40a, a swing arm 40b, a movable shaft 40c, and a connecting portion 40d. The intermediate support arm 40, the left support arm 41, and the right support arm 42 are disposed in the longitudinal center of the casing body 6 and on the left and right sides thereof, and the intermediate support arm 40 is attached near the rear end portion 11b. 41 and the right support arm 42 are attached near the front end portion 11a and support the horizontal blade 11.

  The left support arm 41 and the right support arm 42 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 intermediate support arm 40, the left support arm 41, and the right support arm 42 are not supported by connecting portions 40d, 41a, and 42a connected to the horizontal blade 11, but are supported by a ball joint (not shown). Therefore, not only forward and backward rotation with the horizontal blade 11 supported, but also left and right rotation around the connecting portion 40d of the intermediate support arm 40 can be handled.

  The rotation arm 40a of the intermediate support arm 40 is supported at one end side connected to the casing body 6 by a drive shaft (not shown) and can be rotated around the drive shaft. The other end side of the rotation arm 40a and one end side of the swing arm 40b are connected by a movable shaft 40c, and the swing arm 40b can swing around the movable shaft 40c. Further, the other end side of the swing arm 40b is supported by the horizontal blade 11 by a connecting portion 40d of a ball joint (not shown), and the swing arm 40b can swing around the connecting portion 40d.

  The position where the horizontal blade 11 is connected by the connecting portion 40d is that the axis connecting the connecting portions 41a, 42a connecting the left support arm 41 and the right support arm 42 is close to the front end portion 11a, while the rear end portion It is close to 11b. As described above, since the position of the connecting portion 41d of the swing arm 40b and the axis connecting the connecting portions 41a and 42a of the left support arm 41 and the right support arm 42 is shifted in the front-rear direction of the horizontal blade 11, the rotating arm 40a is By rotating, the horizontal blade 11 can be rotated. Further, when the swing arm 40b swings, the distance between the drive shaft on one end side of the swing arm 40a and the connecting portion 40d of the swing arm 40b can be changed. In the wind direction device, the horizontal blades 11 are parallel by adjusting the amount of protrusion of the intermediate support arm 40, the left support arm 41, and the right support arm 42 by the rack and pinion mechanism and adjusting the rotation angle of the horizontal blade 11 by the drive shaft. By combining the movement and the rotational movement, the horizontal blade 11 can take various postures.

  The left and right support arms 41 and 42 are driven by a rack and pinion mechanism so that the movement amounts of the left support arm 41 and the right support arm 42 are the same, and the rotation of the rotation arm 40a follows the movement of the left support arm 41 and the right support arm 42. As a result, the horizontal blades 11 are moved in parallel. Thereby, for example, as shown in FIG. 6, the horizontal blade 11 takes a horizontal posture. When the left support arm 41 and the right support arm 42 are further extended from the posture of FIG. 6 and the intermediate support arm 40 is rotated counterclockwise when viewed from the right side surface 2c, the front end portion 11a is moved as shown in FIG. The horizontal blade | wing 11 can be made to take the attitude | position which fell and opened ahead. When the left support arm 41 and the right support arm 42 are further extended from the posture of FIG. 6 and the intermediate support arm 40 is rotated clockwise as viewed from the right side surface 2c, the rear end portion 11b is moved as shown in FIG. The horizontal blade | wing 11 can be made to take the attitude | position which fell and opened below. Moreover, the horizontal blade | wing 11 can be tilted to the left or the right by making the amount (movement amount) to which the left support arm 41 and the right support arm 42 extend differ.

<Vertical blade drive mechanism>
In addition to the horizontal blade | wing 11 and the vertical blade | wing 12 which were demonstrated above, and the horizontal blade | wing drive mechanism for driving them, the wind direction apparatus of an air conditioning apparatus is provided with the vertical blade | wing drive mechanism. As shown in FIGS. 9A, 9B and 9C, the vertical blade 12 includes a first vertical blade 12x provided in the vicinity of both left and right ends of the air outlet 7, and a first A second vertical blade 12y provided closer to the center of the air outlet 7 than the vertical blade 12x is included.

  The vertical blade driving mechanism includes a stepping motor 20f for driving the first vertical blade 12x and the second vertical blade 12y. Note that one stepping motor is provided on each of the left and right sides, but the illustration of the stepping motor provided on the left side is omitted. In addition, the first vertical blade 12x, the second vertical blade 12y, and the left portion of the vertical blade driving mechanism described below have a symmetric structure with the right portion, so only the right portion is shown and described. Illustration and description of the left part are omitted.

  The first vertical blade 12x is fixed to a transmission shaft 21f for transmitting driving force by a support arm 22f. The transmission shaft 21f is connected to the stepping motor 20f via the crankshaft 24f. When the stepping motor 20f rotates, the transmission shaft 21f rotates with the rotation, and the support arm 22f also rotates. FIG. 9A shows a state in which the stepping motor 20f rotates clockwise, the support arm 22f comes into contact with the casing body 6, and the first vertical blade 12x is retracted to the back of the air outlet 7. In the state of Fig.9 (a), the front-end | tip part of the blowing side of the 1st vertical blade | wing 12x is substantially perpendicular | vertical with respect to the left-right direction. FIG. 9B shows a state in which the stepping motor 20f rotates counterclockwise by a predetermined angle from the state of FIG. 9A and the first vertical blade 12x slightly protrudes from the outlet 7. . In the state of FIG. 9B, the first vertical blade 12x is moved so that the tip end portion on the blowing side opens outward. Thereby, it arrange | positions so that the guide surface 12xa of the 1st vertical blade | wing 12x may open toward the outer side of the blower outlet 7. FIG. FIG. 9C shows a state in which the stepping motor 20f further rotates counterclockwise from the state of FIG. 9B, and the support arm 22f abuts against the casing body 6 and stops. In the state of FIG. 9C, the angle formed by the guide surface 12xa of the first vertical blade 12x and the left-right direction is larger than that in FIG. 9B.

  The second vertical blade 12y is connected to a crank arm 25f for transmitting driving force via a vertical blade connecting rod 26f. The crank arm 25f is connected to the stepping motor 20f via the crankshaft 24f. When the stepping motor 20f rotates, the crank arm 25f rotates with the rotation and the vertical blade connecting rod 26f linearly extends in the left-right direction. Move on. The vertical blade connecting rod 26f is attached to the crank arm 25f by a crank pin 27f so that the vertical blade connecting rod 26f can rotate around the crank pin 27f. FIG. 9A shows a state in which the stepping motor 20f rotates clockwise, the vertical blade connecting rod 26f moves to the left, and the second vertical blade 12y is tilted to the left. At this time, the second vertical blade 12y is pushed by the vertical blade connecting rod 26f, is deformed by being pushed by the vertical blade connecting rod 26f, and is bent to the left. In FIG. 9B, the stepping motor 20f rotates counterclockwise by a predetermined angle from the state of FIG. 9A, the vertical blade connecting rod 26f moves to the right, and the second vertical blade 12f moves in the left-right direction. The state of being perpendicular to the figure is shown. In FIG. 9C, the stepping motor 20f further rotates counterclockwise from the state of FIG. 9B, the vertical blade connecting rod 26f moves to the right, and the second vertical blade 12y is tilted to the right. The state is shown.

  FIG. 10 is a partially broken perspective view corresponding to FIG. 9A described above, FIG. 11 is a partially broken perspective view corresponding to FIG. 9B, and FIG. 9C is a partially broken perspective view. The figure is FIG. In the above description, the stepping motor 20f directly rotates the crankshaft 24f, the rotation of the crankshaft 24f is transmitted to the transmission shaft 21f and the crank arm 25f, and the transmission shaft 21f and the crank arm 25f rotate at the same time as an example. Yes. However, the transmission shaft 21f and the crank arm 25f do not always rotate simultaneously. Although not shown, a clutch mechanism is incorporated in the transmission shaft 21f, and the coupling between the crankshaft 24f and the transmission shaft 21f can be released. Thereby, only the crank arm 25f can be driven by the crankshaft 24f in a state where the transmission shaft 21f is stopped at a predetermined position. At this time, the stop position of the transmission shaft 21f is maintained, for example, by frictional resistance between the support arm 22f and the casing body 6.

  In the state shown in FIG. 10, the rear portion 12xd of the first vertical blade 12x is in contact with the right side wall 10b. In the state shown in FIG. 10, the air flow 30f blown out along the first vertical blades 12x is diagonally left forward because the portion near the rear portion 12xd of the first vertical blades 12x faces left diagonally forward. In the state shown in FIG. 11, the airflow 31 f that is strongly blown out along the first vertical blade 12 x is about the middle between the forward direction and the right direction. Therefore, in the state shown in FIG. 11, the conditioned air blowing area can be expanded in the left-right direction and blown out at a wide angle. The airflow 32f blown out along the first vertical blade 12x in the state shown in FIG. 12 is substantially parallel to the left-right direction. In the state shown in FIG. 12, the conditioned air blowing region can be expanded to a place along the wall W.

  In the state of FIG. 11 and FIG. 12, the first vertical blade 12 x protrudes from the air outlet 7. Since the shape of the blower outlet 7 is also various, even if it says that the 1st vertical blade | wing 12 protrudes rather than the blower outlet 7, it may not be decided uniquely. For example, as shown in FIG. 4, the front direction of the blower outlet 7 protrudes from the left-right direction. In this case, it is not clear whether it should protrude from the front direction of the blower outlet 7 or from the left-right direction. Therefore, projecting from the air outlet 7 in this embodiment is defined as projecting from the left and right ends of the air outlet 7 in a side view. For example, in FIG. 11 and FIG. 12, it can be said that the first vertical blade 12x protrudes from the right end 7a of the air outlet 7 and thus protrudes. This is because the right side wall 10b of the blowout passage 10 prevents the diffusion of the air flow in the left-right direction. For example, if at least the first vertical blade 12x protrudes from the right end 7a, the effect of the right side wall 10b is eliminated. This is because of its meaning. If defined in this way, even when the left and right end portions are high or low, the first vertical blade 12x protrudes when viewed from the side as much as possible.

  In the above description, the state during the cooling operation in which the horizontal blades 11 are opened as shown in FIG. 7 is taken as an example, but the state during the heating operation shown in FIG. 8 and the horizontal state as shown in FIG. The same operation is possible when the blade 11 is parallel to the outlet 7. Then, as described above, the first vertical blade 12x protrudes more than the second vertical blade 12y to have the effect of diffusing the airflow in the left-right direction.

  Since the second vertical blade 12y is connected by two vertical blade connecting rods 26e and 26f as shown in FIG. 4, the second vertical blade 12y is divided into two groups: a group A near the left side surface 2b and a group B near the right side surface 2c. Can be divided. The swinging direction is independent for group A and group B connected to different vertical blade connecting rods 26e and 26f. For example, when group A is tilted to the right, group B may tilt 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. Naturally, the second vertical blades 12y belonging to the group A and the group B can be swung in the same direction.

<Control unit>
By adjusting the blowing direction of the horizontal blades 11 and the vertical blades 12, and by adjusting the wind speed of the cross flow fan 9, a flow of conditioned air for appropriate air conditioning corresponding to the indoor form and the indoor situation is generated. Can do. In order to control the horizontal blades 11, the vertical blades 12, the cross flow fan 9, and the like, a control unit 50 as shown in FIG. 13 is provided. The control unit 50 includes an indoor control unit 51 for controlling each device of the indoor unit 2 and an outdoor control unit 52 for controlling each device of the outdoor unit. The indoor control unit 51 and the outdoor control unit 52 is connected by a signal line 53.

  The outdoor control unit 52 is connected to a compressor 54, an outdoor electric expansion valve 55, a four-way switching valve 56, an outdoor fan 57, a plurality of pressure sensors 58, a plurality of temperature sensors 59, and the like. The outdoor control unit 52 controls the refrigerant circulation amount of the refrigerant circuit by controlling the rotational speed of the compressor 54, 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 55. To do. The outdoor control unit 52 switches the circulation path of the refrigerant flowing in the refrigeration circuit by switching the four-way switching valve 56 to control operation switching such as switching between heating operation and cooling operation. The outdoor control unit 52 controls the heat exchange efficiency in the outdoor heat exchanger by controlling the rotational speed of the outdoor fan 57. Therefore, the outdoor control unit 52 uses the temperature and pressure of each part detected by a plurality of pressure sensors 58 and temperature sensors 59 installed in the refrigerant circuit and each device for judgment for control.

  On the other hand, the indoor control unit 51 is connected to a transmission / reception unit 60, a horizontal blade driving mechanism 61, a vertical blade driving mechanism 62, a crossflow fan motor 63, a temperature sensor 64, a display unit 65, and the like. The indoor control unit 51 transmits and receives data between the user's remote controller and the transmission / reception unit 60 for control. The indoor control unit 51 controls the horizontal blade driving mechanism 61, the vertical blade driving mechanism 62, and the crossflow fan motor 63 according to the indoor state and the user's setting, and the angle and fluctuation of the horizontal blade 11 and the vertical blade 12 are controlled. The state of movement and the rotational speed of the motor 63 for the crossflow fan can be adjusted to change the blowing direction and the strength of blowing the conditioned air. The indoor control unit 51 uses state information such as the temperature of each part detected by a plurality of temperature sensors 64 or the like installed in the refrigerant circuit or each device for judgment for control. In addition, the indoor control unit 51 notifies the user of the setting state and environment of the indoor unit 2 via the display unit 65.

  The horizontal blade drive mechanism 61 controlled by the indoor control unit 51 includes a left support arm so that the horizontal blade 11 can be driven to tilt left or right in addition to driving the horizontal blade 11 to be pushed out or stored. A drive unit 66 and a right support arm drive unit 67 are provided. And the indoor control part 51 can drive the left support arm drive part 66 and the right support arm drive part 67 independently. Further, an intermediate support arm driving unit 68 is provided to drive the intermediate support arm 40. When the parallel movement of the horizontal blade 11 is performed, the indoor control unit 51 controls the movement amount of the left support arm 41 and the movement amount of the right support arm 42 to be the same, so that the horizontal blade 11 moves in parallel. The support arm drive unit 68 causes the intermediate support arm 40 to follow the left support arm 41 and the right support arm 42. When the horizontal blade 11 is tilted left or right, control is performed so that the amount of movement of the left support arm 41 and the amount of movement of the right support arm 42 are different.

  When the horizontal blade 11 is released from the state where the blower outlet 7 is blocked to bring the horizontal blade 11 into a desired state, the indoor control unit 51 first performs a left support arm drive unit 66 and a right support arm drive unit 67 to the left. The support arm 41 and the right support arm 42 are moved, and the horizontal blades 11 are pushed out in parallel. At this time, the intermediate support arm driving unit 68 rotates the rotating arm 40a following the operation of protruding so that the horizontal blade 11 moves in parallel. Thereby, although the blower outlet 7 blocked by the ejection of the horizontal blades 11 is opened, the horizontal blades 11 are smoothly opened without being strongly rubbed around the blower ports 7.

  Next, while the left support arm 41 and the right support arm 42 are fixed, the rotation arm 40a is rotated by the intermediate support arm drive unit 68, and the connecting portion 41a of the left support arm 41 and the right support arm 42 are rotated. The horizontal blade 11 is rotated around an axis connecting the connecting portion 42a. The horizontal blade 11 can be moved to a desired state by the two-step operation of the parallel movement and the rotational movement as described above.

  The indoor control unit 51 performs control so that the horizontal blades 11 are moved to a desired state in one step by performing the two-step operation as described above in parallel and performing a rotational movement while performing the parallel movement. You can also

  The indoor control unit 51 includes a right stepping motor 20f, a left stepping motor (not shown), a right clutch mechanism (not shown), and a left clutch mechanism (not shown) shown in FIG. To control. The clutch mechanism can be composed of, for example, an electromagnet or the like, and the first vertical blade 12x and the second vertical blade 12y on the right side driven by the vertical blade drive mechanism 62 are controlled by these controls to turn on and off the electromagnet. In addition, the determination of the stop positions of the left first vertical blade 12x and the second vertical blade 12y and the continuous swing operation can be performed independently.

<Airflow of vertical blades and conditioned air>
(Blowout during cooling operation)
The flow of conditioned air during the cooling operation will be described with reference to FIGS. 14, 15, 16, 17, 18, and 20. 14 (a), 15 (a), 16 (a), 17 (a), 18 (a) and 20 (a) are front views, and FIG. 14 (b) and FIG. 15 (b). 16 (b), FIG. 17 (b), FIG. 18 (b) and FIG. 20 (b) are right side views, FIG. 14 (c), FIG. 15 (c), FIG. 16 (c), FIG. c), FIG. 18 (c) and FIG. 20 (c) are bottom views. In addition, the air flow is indicated by arrows in FIGS. 14, 15, 16, 17, 18, and 20. FIG. 20 is a diagram for explaining the airflow of a conventional air conditioner for comparison, and shows an indoor unit of a type that blows conditioned air in the left-right direction by wind direction blades.

  The airflow 33 shown in FIG. 14 opens the horizontal blade 11 so that the front end portion 11a is located slightly below the rear end portion 11b during the cooling operation, and the first vertical blade 12x and the second vertical blade 12y. Is occurring in the state of facing the center. A method of forming the state shown in FIG. 14 will be described by taking the first vertical blade 12x on the right side as an example. When the power is turned off, the first vertical blade 12x is energized and stored. Then, in order to obtain the state shown in FIG. 14, the clutch mechanism of the transmission shaft 21f is released, and the transmission shaft 21f and the crankshaft 24f are uncoupled. Then, the stepping motor 20f is rotated clockwise, and the second vertical blade 12y is tilted to the left with respect to the front as shown in FIG. 9B. At this time, since the clutch mechanism of the transmission shaft 21f is opened, the first vertical blade 12x is kept in the housed state, and the rear portion 12xd of the first vertical blade 12x is inclined to the left with respect to the front. ing. As a result, as shown in FIG. 14, the first vertical blade 12x and the rear portion 12xd of the second vertical blade 12y are inclined to the left with respect to the front.

  In the cooling operation, the air flow 34 shown in FIG. 15 opens the horizontal blades 11 and opens the horizontal blades 11 in the same manner as in FIG. 14, and the first vertical blades 12x and the second vertical blades 12y move forward. Is generated in a state of being substantially parallel (perpendicular to the left-right direction). A method of forming the state shown in FIG. 15 will be described by taking the first vertical blade 12x on the right side as an example. In order to obtain the state shown in FIG. 15, first, the second vertical blade 12 y is inclined toward the center of the air outlet 7 as shown in FIG. In this state, the clutch mechanism of the transmission shaft 21f is released so that the transmission shaft 21f and the crankshaft 24f are in a non-coupled state. Next, the stepping motor 20f is rotated counterclockwise, and the second vertical blades 12y are directed substantially parallel to the front as shown in FIG. 9B. At this time, since the clutch mechanism of the transmission shaft 21f is opened, the first vertical blade 12x does not rotate, and the first vertical blade 12x is kept parallel to the front, unlike FIG. 9B. . As a result, a state is formed in which the second vertical blade 12y is parallel to the front in a state where the first vertical blade 12x is housed as shown in FIG.

  The airflow 35 shown in FIG. 16 opens the horizontal blades 11 in the cooling operation in the same manner as in FIG. 14, directs the second vertical blades 12y substantially horizontally with respect to the front, and the first vertical blades 12x. Is generated in a state of slightly protruding from the air outlet 7. Such states of the first vertical blade 12x and the second vertical blade 12y coincide with the state shown in FIG. 9B. The state shown in FIG. 16 (the state shown in FIG. 9B) is connected to the clutch mechanism of the transmission shaft 21f from the state shown in FIG. 14 (the state shown in FIG. 9A). It can be formed by making a predetermined rotation around.

In the cooling operation, the air flow 36 shown in FIG. 17 opens the horizontal blade 11 in the same manner as in FIG. 14, tilts the second vertical blade 12y of the left half (group A) to the left, and the right half (group). The second vertical blade 12y of B) is tilted to the right, and the first vertical blade 12x is generated in a state where the first vertical blade 12x protrudes slightly from the air outlet 7 as in FIG. In order to form the state of FIG. 17, the clutch mechanism of the transmission shaft 21f is released from the state of FIG. 15, and only the crank arm 25f is rotated counterclockwise by the stepping motor 20f. Thereby, while the first vertical blade 12x maintains the state of FIG. 15, the second vertical blade 12y of the right half (group B) faces rightward as shown in FIG. 9C.
The airflow 37 shown in FIG. 18 opens the horizontal blade 11 in the cooling operation during the cooling operation, tilts the second vertical blade 12y as in the state of FIG. 17, and causes the first vertical blade 12x to move. This occurs in a state of further protruding from the state of FIG. The state shown in FIG. 18 corresponds to the state shown in FIG. The state shown in FIG. 18 (the state shown in FIG. 9C) is connected to the clutch mechanism of the transmission shaft 21f from the state shown in FIG. 14 (the state shown in FIG. 9A). It can be formed by rotating around.

  The airflow in the state shown in FIGS. 14 to 18 will be described. In the state shown in FIG. 14, the rear portions 12xd of the left and right first vertical blades 12x are in contact with the left side wall and the right side wall (see FIG. 9). Therefore, it is difficult for airflow to flow toward the back surface 12xb of the first vertical blade 12x. And the airflow 33 of FIG. 14 is toward the center of the blower outlet 7, and in the state of FIG. 14, it can collect airflow in the blower outlet 7, and can blow strong conditioned air toward the front. The air flow 34 in FIG. 15 is directed straight forward, and in the state of FIG. 15, strong conditioned air can be blown forward. The airflow 33 in FIG. 14 and the airflow 35 in FIG. 15 differ in whether or not the airflow is concentrated toward the center, and the stored first vertical blade 12x helps the airflow to be concentrated by the rear portion 12xd.

  In contrast to the air flow 34 in FIG. 15, the air flow 35 in FIG. 16 is such that the first vertical blades 12 x protrude toward the outside of the air outlet 7 relative to the second vertical blades 12 y and are inclined in the left-right direction. The airflow slightly spreads in the left-right direction on the side closer to the left and right end portions of 7. The airflow 36 in FIG. 17 further spreads as the group A and the group B of the second vertical blades 12y are inclined in different directions with respect to the airflow in FIG. Then, since the direction of the conditioned air is changed in the left-right direction by tilting the second vertical blade 12y, the wind speed and the air volume of the conditioned air guided to the left and right by the first vertical blade 12x are increased. However, as can be seen from FIGS. 16 (c) and 17 (c), the air flow of conditioned air blown out from the air outlet 7 is small in the direction facing the left side surface 2b and the right side surface 2c.

  On the other hand, in the airflow 37 of FIG. 18, the first vertical blade 12x protrudes from the outlet 7 and opens in a C shape, so that an airflow of conditioned air is generated in the direction where the left side surface 2b and the right side surface 2c face. The airflow 37 in FIG. 18 is directed seamlessly over the entire 180 degrees ahead from the direction facing the left side surface 2b through the direction facing the front surface 2a to the direction facing the right side surface 2c. This state is shown in FIG. 19B as seen from the top side. The first vertical blade 12x protrudes forward from the position of the top of the right side wall 10b of the outlet passage 10 (dashed line). Therefore, the airflows 37b and 37c guided by the first vertical blade 12x from the airflow 37a guided to the right by the second vertical blade 12y are blown in parallel toward the right without being influenced by the right side wall 10b. At this time, the airflow 37b is guided along the guide surface 12xa of the first vertical blade 12x, and the airflow 37c is guided by the back surface 12xb of the first vertical blade 12x. Thus, by using the back surface 12xb of the first vertical blade 12x, more airflow can be generated in the right direction. Further, in this state, the first vertical blade 12x protrudes to the right side of the extension line (two-dot chain line) of the right side wall 10b of the blowout passage 10. Therefore, the effect of inducing conditioned air to the right is increased.

  On the other hand, since the conventional vertical wind direction plate 128 shown in FIG. 19A is located behind the top 110a of the side wall 110, the air flow directions D1 and D2 of the conditioned air guided to the left by the vertical wind direction plate 128 are also included. The direction is changed forward along the side wall 110. Therefore, the air flow directions D3 and D4 of the conditioned air finally blown out from the air outlet 107 are directed obliquely forward, and the air flow direction substantially parallel to the left-right direction cannot be obtained.

  In addition, the conventional indoor unit 200 as shown in FIGS. 20 (a), 20 (b) and 20 (c) generates a conditioned air flow in the left and right directions by the side wind direction plates 213 and 214. In the shaded area 240, there is almost no airflow. This is because the casing body 206 for providing the side wind direction plates 213 and 214 or the side wind direction plates 213 and 214 blocks the air flow of the conditioned air, resulting in a portion without the air flow 230. That is, the airflow 230 whose airflow is adjusted by the vertical airflow direction adjusting plate 212 and the horizontal airflow direction adjusting plate 211 and blown from the outlet 207, and the airflow whose airflow direction is adjusted by the vertical airflow direction adjusting plate 212 and the side airflow direction plates 213 and 214. This is because two of 231 occur separately and it is difficult to connect them without break.

(Blowout during heating operation)
The blowing of the heating operation will be described with reference to FIG. FIG. 21 (a) shows the front of the indoor unit during heating operation, FIG. 21 (b) shows the right side, and FIG. 21 (c) shows the bottom. The difference between the case where the first vertical blades 12x in the vicinity of the left side wall and the right side wall are accommodated and the case where the first vertical blades 12x in the vicinity of the left side wall are protruded in the explanation of the air blowing operation during the cooling operation described above. Even at the time, the induction of conditioned air by the first vertical blades 12x has the same effect as in the cooling operation. Therefore, there is no need to repeat the adjustment of the airflow by the first vertical blade 12x during the heating operation, but here, a brief description will be given of a case where the first vertical blade 12x protrudes most during the heating operation.

  The air flow 38 shown in FIG. 21 opens the horizontal blade 11 so that the front end portion 11a is located above the rear end portion 11b during the heating operation, and the first vertical blade 12x and the right side wall in the vicinity of the left side wall. The first vertical blade 12x in the vicinity is opened and the vertical blade 12 is tilted with respect to the vertical direction.

  21A, the airflow 38 includes airflows 38b and 38d that are directed toward the left side surface 2b, and airflows 38c and 38e that are directed toward the right side surface 2c. The airflow 38b is guided along the back surface 12xb of the left first vertical blade 12x, and the airflow 38d is guided along the guide surface 12xa of the left first vertical blade 12x. The airflow 38c is guided along the back surface 12xb of the right first vertical blade 12x, and the airflow 38e is guided along the guide surface 12xa of the right first vertical blade 12x.

  And when FIG.21 (c) is seen, the airflow 38d is influenced by the airflow 38a which goes to the downward direction of the front surface 2a, and includes what goes diagonally forward. Similarly, the airflow 38e includes an airflow that is influenced by the airflow 38a that is directed downward from the front surface 2a and that is directed obliquely forward. By adjusting the angle of the horizontal blade 11 and the angle of the first vertical blade 12x near the left side wall and the right side wall, the direction facing the left side surface 2b of the indoor unit 2, the direction facing the right side surface 2c, and the front surface 2a It is possible to adjust the conditioned air blown in the direction between them as well as the facing direction.

(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. 22 (a) shows a front view of the indoor unit in the insensitive airflow mode, FIG. 22 (b) shows a right side view of the indoor unit, and FIG. 22 (c) shows a bottom view of the indoor unit. Show. In the insensitive airflow mode, the front end portion 11a of the horizontal blade 11 is slightly raised from the rear end portion 11b, and the upper surface of the horizontal blade 11 faces the air outlet. That is, the posture of the horizontal blade 11 in the insensitive airflow mode is substantially parallel to the posture in which the horizontal blade 11 closes the outlet 7. The posture of the horizontal blade 11 is as shown in FIG. 22 by causing the horizontal blade 11 to squeeze out so that the upper surface of the horizontal blade 11 is orthogonal to the air flow blown out from the air outlet 7. When the horizontal blades 11 are kept at an angle orthogonal to the air flow blown from the outlet 7, the conditioned air hits the horizontal blades 11 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 FIG. 22 is a state in which the front end portion 11a is slightly lowered as compared with the state in which the upper surface of the horizontal blade 11 is perpendicular to the blowing direction of the laminar flow blown from the blower outlet 7. In this state, the airflow is weakened by hitting the horizontal blades 11, but it can be said that the flow of the conditioned air to the rear hardly exists or is extremely weak. In FIG. 22, an extremely weak air flow generated at the rear is indicated by an arrow smaller than an arrow directed forward or in the left-right direction. At this time, the number of rotations of the cross flow fan 9 is also reduced, and the amount of air blown from the outlet 7 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 11 to reduce the wind speed, thereby making it difficult for a person to feel the air flow.

  In the state shown in FIG. 22, the gap formed between the casing body 6 and the horizontal blade 11 is narrow. This makes it easier to increase the amount of conditioned air blown out in the left-right direction, that is, the direction in which the left side surface 2b and the right side surface 2c face. Furthermore, as can be seen from FIG. 22A and FIG. 22B, the horizontal blades 11 cooperate with the first vertical blades 12x to induce conditioned air in the left-right direction. Since the horizontal blades 11 are immediately below the first vertical blades 12x, more conditioned air can be guided in the left-right direction.

(Adjustment of left and right airflow)
The adjustment of the left and right air volume can be performed mainly by the inclination of the vertical blade 12 as described above. Further, the left and right airflows can be adjusted by tilting the horizontal blade 11 to the left as shown in FIGS. 23 and 24 or by tilting the horizontal blade 11 to the right although not shown. At that time, only one of the first vertical blades 12x near the left side wall and the first vertical blades 12x near the right side wall is opened, or the opening angle of each is changed, thereby further adjusting the left and right air volumes. be able to.

<Modification>
(1) In the above embodiment, the case of the wall-mounted indoor unit 2 has been described. However, the type of the indoor unit is not limited to the wall-mounted type, and may be a stationary type or other types. Also good.

  (2) In the above-described embodiment, a case has been described in which two first vertical blades 12x are arranged on each of the left and right, but two or more first vertical blades 12x may be arranged on the left and right. . In that case, the operations of the plurality of first vertical blades 12x arranged may be different on the right side, for example, or may be independent from each other. In this case, the left and right first vertical blades may be operated independently as in the above embodiment.

  (3) In the above embodiment, the case where the first vertical blade 12x in the vicinity of the right side wall 10b and the second vertical blade 12y belonging to the group B are driven by the same stepping motor 20f has been described. For example, two stepping motors are used. May be used to drive the first vertical blade 12x and the second vertical blade 12y separately. Also, the left side can be configured similarly to the right side.

<Features>
(A)
The indoor unit 2 of the air conditioner 1 includes a casing body 6 having an air outlet 7, a first vertical blade 12x in the vicinity of the left side wall 10a of the outlet passage 10, and a first vertical blade 12x in the vicinity of the right side wall 10b. . The indoor unit 2 includes the second vertical blades 12y between the first vertical blades 12x, that is, near the center of the air outlet 7.

  The first vertical blade 12x is rotated by a stepping motor 20f or the like (drive source) that constitutes the vertical blade driving mechanism 62, so that the first vertical blade 12x moves so as to protrude outward of the air outlet 7 from the second vertical blade 12y. . As the first vertical blade 12x protrudes as described above, the conditioned air is more outside the outlet 7 than the case where the second vertical blade 12y is configured by only the vertical blade that changes the angle in the left-right direction. The airflow direction can be changed, and the airflow can be widened in the left-right direction (longitudinal direction of the air outlet 7). At this time, since only the direction of the airflow is changed by the vertical blades, it is possible to blow the conditioned air without any unevenness as a whole.

  Then, as shown in FIG. 19 (b), by causing the first vertical blade 12 x to protrude from the outlet 7, the conditioned air whose air direction has been changed by the first vertical blade 12 x is changed to the left side wall 10 a or the right side of the outlet passage 10. Since it is not necessary to change the direction of the wind again when it hits the wall, it becomes easier to blow out conditioned air in the left-right direction at a wide angle. That is, by projecting the first vertical blade 12x, more conditioned air can be blown out in the left-right direction. In addition, in this invention, the 1st vertical blade | wing 12x protrudes from the blower outlet 7 is projecting from the right-and-left end part of the blower outlet 7 in side view.

  Particularly, when the first vertical blade 12x protrudes from the air outlet 7, the direction of the guide surface 12xa of the first vertical blade 12x changes because of the rotation of the stepping motor 20f or the like. 9B and FIG. 9C are more open toward the outside of the air outlet 7 than FIG. 9B. In other words, the state of FIG. 9 (b) is inclined toward the right side wall 10b than the state of FIG. 9 (a), and the state of FIG. 9 (c) is more than that of FIG. 9 (b). Furthermore, it inclines toward the right side wall 10b. By adjusting the inclination angle, the first vertical blade 12x can be directed to a state more suitable for blowing in the left-right direction. Thereby, control of the conditioned air spreading in the left-right direction is facilitated.

(B)
The 2nd vertical blade | wing 12y is comprised by the member softer than the 1st vertical blade | wing 12x. And as shown to Fig.9 (a) and FIG.9 (b), it is comprised by the vertical blade | wing connecting rod 26f so that it can deform | transform into right and left. The opposite side of the portion to which the vertical blade connecting rod 26f is connected is fixed perpendicular to the forward direction, and is also fixed by the vertical blade connecting rod 26f, so even if a soft member that deforms is used, The direction of the conditioned air can be changed. On the other hand, the first vertical blade 12x is supported by a support arm 22f fixed to the back surface 12xb. The support arm 22f is fixed to a part of the first vertical blade 12x with two plate-like members in order to rotate the first vertical blade 12x. The first vertical blade 12x is made of a member having higher rigidity than the second vertical blade 12y so that the first vertical blade 12x does not deform even if it is not supported by the support arm 22f as a whole. For example, even if the first vertical blade 12x and the second vertical blade 12y are formed of the same plastic material, a desired high rigidity can be obtained by increasing the thickness of the first vertical blade 12x.

  In the above-described embodiment, the first vertical blade 12x has the guide surface 12xa curved in a convex shape toward the center of the air outlet 7. The conditioned air can be smoothly guided along the curved guide surface 12xa, and the wind direction can be efficiently changed from the parallel direction to the vertical direction toward the front of the outlet 7. Since the curved first vertical blades can be easily blown out at a wide angle, the first vertical blades 12x can be designed compactly, and the indoor unit 2 of the air conditioner 1 can be easily downsized.

  In addition, since the guide surface 12xa is curved in this convex manner, as shown in FIG. 14, in the state in which the first vertical blade 12x is stored, the first vertical blade 12x on the left side generates an air flow toward the right. The first vertical blade 12x on the right side can generate an air flow toward the left. Thereby, since the airflow of conditioned air is collected in the center, conditioned air can be strongly blown out toward the front.

  When the first vertical blade 12x is viewed from the back surface 12xb, it is curved in a concave shape. With the concavely curved back surface 12xb, for example, as shown in FIG. 19B, the direction of the conditioned air flow can be changed in parallel to the left-right direction. Therefore, more conditioned air can be blown out in parallel with the left-right direction by the first vertical blades 12x.
