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.

  The air conditioner includes an indoor unit installed indoors for air conditioning in the room. For example, in the case of a wall-mounted indoor unit, an air conditioner indoor unit includes an indoor heat exchanger in the main body casing, sucks indoor air into the main body casing by a blower fan such as a crossflow fan, and passes through the indoor heat exchanger. The conditioned air is blown out of the main body casing mainly from the blowout port toward the front.

  In general, in order to control the wind direction of the conditioned air blown from the air outlet, left and right wind direction changing blades that adjust the wind direction in the left and right direction and vertical wind direction changing blades that adjust the wind direction in the up and down direction are provided. The air outlet of the conventional wall-mounted indoor unit is provided on the front surface of the indoor unit or the bottom surface of the indoor unit, and the vertical wind direction is adjusted by the vertical wind direction changing blades when the indoor unit is in operation.

  In this way, when the wind direction is controlled by the left and right wind direction changing blades and the up and down wind direction changing blades, in order to generate a conditioned air flow in the side surface direction (left and right direction) of the casing body, for example, Patent Document 1 (Japanese Patent Laid-Open No. Hei 8- No. 178407 discloses an example in which the air outlet is provided to extend to both the left and right ends of the front surface of the indoor unit main body.

  As described above, when the outlets are provided at the left and right ends of the indoor unit and the side surfaces of the indoor unit, the conditioned air can be blown out in the left-right direction by adjusting the direction of the vertical louver. By the way, there is an area where you want to blow conditioned air directly from the indoor unit depending on the indoor conditions where the indoor unit is installed and how to use it, but you do not want to directly apply the conditioned air flow blown from the indoor unit May exist.

  Therefore, there is a case in which a mode for restricting the operation of the vertical louver, the left and right shutters, and the horizontal flap is provided so that the air flow of the conditioned air is not directed toward an area where the conditioned air is not directly blown from the indoor unit.

  However, when such a mode is provided, a mismatch occurs between an area that can be selected using an operating device such as a remote controller and an area that can actually be set by the indoor unit. Inconvenience occurs in the operation of the controller.

  An object of the present invention is to eliminate the inconvenience of operation of an operating device when a mode for limiting operations of a vertical louver, left and right shutters, and a horizontal flap is provided in order to limit an area where conditioned air is blown.

  The indoor unit of the air conditioning apparatus according to the first aspect of the present invention includes an airflow control device, a control unit, and an operating device. The airflow adjustment device may adjust the airflow of the conditioned air to send the conditioned air to a selected area selected from a plurality of setting areas in the room. The control unit controls the airflow adjusting device. The operating device has an input unit for inputting an instruction to be given to the control unit and a display unit for displaying the content of the instruction. In addition, the operation device is configured to display an input setting area on the display unit and input a selection area from the input unit. And a control part has an airflow range restriction | limiting mode which restrict | limits the range of the conditioned air guide | induced by the airflow control apparatus. When the airflow range restriction mode is set in the control unit, the operation unit performs restriction so that the setting area included in the range restricted in the airflow range restriction mode cannot be input from the input unit as a selection area. Limits not to be displayed on the screen.

  In general, when the operation of vertical louvers, left and right shutters, and horizontal flaps is restricted, and the selection of a specific area that blows conditioned air is restricted, the setting for blowing conditioned air to that specific area is set from the controller. Functions that can be entered may remain. If the operator selects such a function and the conditioned air is not blown to the selected specific area, the operator of the operating device may be misunderstood and may be mistaken for a failure.

  According to the present invention, by restricting the input from the input unit for the specific setting area whose selection is restricted, only the setting area that can be selected is displayed on the operating device in the first place, and the operator is restricted. The input to the setting area cannot be recognized. For this reason, the operation of the operating device and the operation of the airflow control device always coincide with each other, so that the operator is not misunderstood.

  An indoor unit of an air conditioner according to a second aspect of the present invention is the indoor unit of the air conditioner of the first aspect of the present invention, and further includes a casing body in which a blowout port for blowing out conditioned air is formed. The airflow adjusting device includes a blade that adjusts the angle of the wind direction of the conditioned air blown out from the air outlet. The control unit has an installation position setting mode in which the range of conditioned air to be guided is limited based on the position of the casing body as the airflow range limitation mode. And a control part is comprised so that the change of the angle of the blade | wing which guides conditioned air to the range restrict | limited by the installation position setting mode may be restrict | limited.

  According to the present invention, the setting of restricting the change of the blade angle so as to guide the conditioned air to the range restricted by the installation position setting mode while restricting the conditioned air from being guided by the position where the indoor unit is installed is limited. Since there is no selection function by the controller for the area, the operation of the controller and the range of the conditioned air guided by the blades are the same except for the range where the conditioned air is not guided by the installation position of the indoor unit. An operator can perform an operation.

  An indoor unit of an air conditioner according to a third aspect of the present invention is the indoor unit of the air conditioner of the second aspect, wherein the blade includes a left vertical louver and a right vertical louver. The control unit is configured to limit a change in the angle of the left vertical louver and the right vertical louver that guides conditioned air to a range limited by the installation position setting mode.

  According to the present invention, by restricting the operations of the left vertical louver and the right vertical louver independently, a more detailed setting area can be restricted. As the area setting becomes more complicated, the selection of the setting area that is not restricted can be set without recognizing the restricted setting area, so that the operator's operation comfort can be improved.

  An indoor unit of an air conditioner according to a fourth aspect of the present invention is the indoor unit of the air conditioner of the second or third aspect, wherein the blades adjust the vertical angle of the conditioned air blown from the outlet. Includes horizontal flap. The control unit is configured to limit the change of the angle of the horizontal flap that guides the conditioned air to the range limited by the installation position setting mode.

  According to the present invention, by restricting the movement of the horizontal flap, it is possible to restrict selection of a setting area farther than the casing body or a setting area close to the casing body, and even in such a case, limited setting is possible. Except for the area, the operator can perform the operation in a state where the operation of the operating device and the range of conditioned air guided by the blades coincide.

  An indoor unit of an air conditioner according to a fifth aspect of the present invention is the indoor unit of the air conditioner according to any of the second to fourth aspects of the present invention, wherein the outlet is a central outlet for blowing conditioned air forward and In addition, a left side outlet and a right side outlet are provided in communication with the central outlet and provided on the left and right in the longitudinal direction of the central outlet to blow out conditioned air in the left and right direction. The airflow control device includes a left shutter that opens and closes the left side outlet and a right shutter that opens and closes the right side outlet. The control unit limits the opening operation of the left shutter or the right shutter that blows out conditioned air to the range limited by the installation position setting mode.

  According to the present invention, by restricting the movement of the left shutter and the right shutter, it is possible to easily limit the selection of the setting area on the left side or the setting area on the right side of the casing body. As described above, by restricting the movement of the left shutter and the right shutter, it is possible to restrict the setting area in more detail. As the area setting becomes more complicated, the selection of the setting area that is not restricted can be set without recognizing the restricted setting area, so that the operator's operation comfort can be improved.

  An indoor unit of an air conditioner according to a sixth aspect of the present invention is the indoor unit of the air conditioner according to any of the first to fifth aspects of the present invention, wherein the operating unit circulates through the setting area by operating the input unit. The selection area is selected while switching.

  According to the present invention, since there are no setting areas that cannot be selected, the types of setting areas that can be switched cyclically are reduced, and the input time is shortened.

  In the indoor unit of the air conditioner according to the first aspect of the present invention, even when a mode for restricting the operation of the vertical louver, the left and right shutters, and the horizontal flap is provided to restrict the area for guiding the conditioned air, the operation unit is restricted. Therefore, there is no discrepancy between the area for guiding conditioned air and the mode selection function, and the inconvenience of operation of the operating device can be eliminated.

  In the indoor unit of the air conditioner according to the second aspect of the present invention, an area where the conditioned air is not guided by the installation position of the indoor unit is excluded, and a setting area which can be selected by the operating unit and an area where the indoor unit guides the conditioned air Therefore, the inconvenience of the operator of the operating device can be solved.

  The air conditioner 1 includes a refrigerant circuit to perform heat exchange and perform indoor air conditioning. The refrigerant circuit includes, for example, an indoor heat exchanger of the indoor unit 2 (functions as an evaporator during cooling / a condenser during heating), and a compressor and outdoor heat exchanger of the outdoor unit 3 (condenses during cooling). And function as an evaporator during heating / heating) and an expansion valve and the like are connected by a refrigerant pipe in the collective connection pipe 4. In addition, in order to control the air conditioner 1, an electrical component box for receiving a command from a control terminal such as the remote controller 5 and controlling indoor equipment such as a fan motor of the indoor unit 2 is provided in the indoor unit 2. The outdoor unit 3 is provided with an electrical component box for controlling outdoor equipment such as a fan motor of the outdoor unit 3. 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>
FIG. 2 shows the front of the indoor unit, and FIG. 3 shows the right side of the indoor unit. As shown in FIGS. 1, 2 and 3, the indoor unit 2 includes a casing body 6, a horizontal flap 11, a left shutter 20a and a right shutter 20b. The indoor unit 2 includes an indoor side heat exchanger (not shown), an indoor fan 9, and a vertical louver 12 inside the casing body 6.

  The casing body 6 of the indoor unit 2 is a substantially rectangular parallelepiped member that is long in the horizontal direction. In the indoor unit 2, five surfaces other than the front surface 2a, the left side surface 2b, the right side surface 2c, the top surface 2d and the bottom surface 2e, that is, the back surface 2f of the casing body 6 are covered with the decorative panel 6a. Note that the direction perpendicular to 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 may be referred to as the left-right direction, and the right hand in front view is the right direction and the left hand in front view is Turn 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.

  An air outlet 7 for blowing out conditioned air is formed from the bottom surface 2e of the casing body 6 to the left side surface 2b and the right side surface 2c, and a suction port 8 for sucking room air is formed in the top surface 2d. Details of the air outlet 7 will be described later.

  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.

  Further, on the upstream side of the cross flow fan 9 in the casing body 6, an indoor-side heat exchanger (not shown) having an inverted V shape in a side view is arranged and before being sucked into the cross flow fan 9. Air conditioning is performed by passing indoor air through the indoor heat exchanger. Thus, the indoor air is efficiently conditioned by sucking the indoor air and blowing out the conditioned air by the cross flow fan 9 extending long in the longitudinal direction of the casing body 6. Therefore, the indoor heat exchanger is also formed in a shape that extends in the longitudinal direction of the casing body 6, and is disposed between the inlet 8 and the outlet 7 that extends in the longitudinal direction. An air filter (not shown) is provided upstream of the indoor heat exchanger, and dust larger than the gap of the air filter is completely removed from the conditioned air guided to the cross flow fan 9.

  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. That is, the indoor air sucked from the suction port 8 on the top surface 2d of the casing body 6 sequentially passes through the air filter and the indoor heat exchanger, and is sent out to the blowing passage 10 by the crossflow fan 9, and the vertical louver 12 The direction of the airflow is adjusted by the horizontal flap 11 and blown out from the outlet 7 on the bottom surface 2 e of the casing body 6.

  As shown in FIGS. 2 and 3, 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 stream from the outlet passage 10 toward the outlet 7 has a directional vector directed downward and a directional vector directed forward, and is a laminar flow with less turbulence.

<Configuration around the outlet>
As shown in FIG. 4, the air outlet 7 includes a central air outlet 7a, a left side air outlet 7b, and a right side air outlet 7c. The outlet passage 10 is divided into a central outlet passage 10A connected to the central outlet 7a, a left outlet passage 10B connected to the left side outlet 7b, and a right outlet passage 10C connected to the right side outlet 7c. The central outlet passage 10A and the left outlet passage 10B are partitioned by a storage portion 25a, and the central outlet passage 10A and the right outlet passage 10C are partitioned by a storage portion 25b, but the central outlet passage 10A and the left outlet passage 10B. And the right outlet passage 10C communicate with each other. The central air outlet 7a is opened and closed by the horizontal flap 11, the left air outlet 7b is opened and closed by the left shutter 20a, and the right air outlet 7c is opened and closed by the right shutter 20b.

  In the indoor unit 2, when the operation is stopped, the horizontal flap 11 is closed and the opening surface 16 of the central outlet 7a is closed, and during operation, the horizontal flap 11 is opened and the opening surface 16 of the central outlet 7a is opened. FIG. 1 shows a state in which the horizontal flap 11 of the central outlet 7a is open, and FIG. 3 shows a state in which the horizontal flap 11 is closed.

  The vertical louver 12 disposed in the blowout passage 10 includes a plurality of blades classified into a left main vertical louver 12a, a right main vertical louver 12b, a left side vertical louver 12c, and a right side vertical louver 12d (see FIG. 4). ). As shown in FIG. 5, the vertical louver 12 is divided into a left louver 19a and a right louver 19b, which are connected by different connecting rods 13a and 13b. The left louver 19a includes a left main vertical louver 12a and a left side vertical louver 12c, and the right louver 19b includes a right main vertical louver 12b and a right side vertical louver 12d. Since the driving force is transmitted from the stepping motors 13c and 13d via the arms 13e and 13f and the connecting rods 13a and 13b are driven independently, the left louver 19a and the right louver 19b are connected to the casing body 6. It can swing left and right independently of each other about a plane perpendicular to the longitudinal direction. Therefore, by controlling the rotation of the stepping motors 13c and 13d, the left main vertical louver 12a and the left side vertical louver 12c, and the right main vertical louver 12b and the right side vertical louver 12d are stopped at an arbitrary angle after swinging. Thus, the conditioned air blowing direction in the left-right direction of the indoor unit 2 can be adjusted.

  In the state shown in FIG. 4, the left side vertical louver 12c and the right side vertical louver 12d are stopped at an angle that does not lead conditioned air to the opened left side outlet 7b and right side outlet 7c. The relationship between the inclination of the vertical louver 12 and the opening and closing of the left side outlet 7b and the right side outlet 7c is as follows. The state of FIG. Does not appear when driving.

  For example, when only the central air outlet 7a is opened and conditioned air is to be concentrated on the central air outlet 7a, the blade surfaces of the left louver 19a and the right louver 19b are in a state of being perpendicular to the longitudinal direction. (FIG. 5A).

  When it is desired to guide the conditioned air toward the right, as shown in FIG. 5B, when the stepping motors 13c and 13d are rotated clockwise, the arms 13e and 13f are rotated around the fulcrums 13g and 13h. The arms 13e and 13f push the connecting rods 13a and 13b to the right, and the vertical louver 12 is tilted to the right.

  The inclination of the vertical louver 12 can be stopped at a desired position by controlling the rotation angle of the stepping motors 13c and 13d. For example, when the state shown in FIG. 5C is rotated by an angle smaller than the rotation angle of the stepping motors 13c and 13d shown in FIG. 5B, the inclination of the angle β smaller than the angle α shown in FIG. The vertical louver 12 can be provided.

  The connecting rod 13a, the stepping motor 13c and the arm 13e shown in FIG. 5 constitute the left louver driving portion 42a of the vertical louver driving mechanism 42, and the connecting rod 13b, the stepping motor 13d and the arm 13f are driven to the right louver of the vertical louver driving mechanism 42. Part 42b is configured.

  In order to drive the vertical louver 12, the horizontal flap 11, the left shutter 20a, and the right shutter 20b as described above, the indoor unit 2 includes the above-described vertical louver driving mechanism 42, a horizontal flap driving mechanism and a shutter driving mechanism, which will be described later. ing. These drive mechanisms are controlled by a control unit described later.

<Shutter>
FIG. 6 is an enlarged view of a portion around the left shutter in order to explain the configuration near the left shutter. FIG. 6A shows a state in which a part around the left shutter is broken and enlarged when the left shutter 20a is closed and the horizontal flap 11 is opened. FIG. 6B shows a state in which a part of the periphery of the left shutter when the left shutter 20a and the horizontal flap 11 are opened is broken and enlarged.

  The left shutter 20a shown in FIGS. 6 (a) and 6 (b) is driven while being supported by the support member 23, and rotates counterclockwise to open the left side outlet 7b to accommodate the storage portion 25a. It is stored in. A driving force is applied to the support member 23 from a stepping motor (not shown) controlled by the control unit 30. A slit 26d for moving the support member 23 is formed in the storage portion 25a, one end 23a of the support member 23 is fixed to the left shutter 20a, and the other end 23b is attached to the rotating shaft. Therefore, the rotation of the left shutter 20a is centered on the other end 23b. The storage portion 25a is deformed into a substantially U shape with the opening facing downward, and a cavity 26c into which the left shutter 20a enters is formed at the center. On the upper end portion 26a of the storage portion 25a, there is a left outlet passage 10B connected to the left side outlet 7b. Since the left shutter 20a rotates and fits in the substantially U-shaped cavity 26c, the cavity 26c is inclined obliquely in a front view, so that the distance between the lower end portion 26b and the upper end portion 26a of the storage portion 25a is reduced, and the left side The opening area of the left outlet passage 10B connected to the outlet 7b can be increased.

  Moreover, the casing main body 6 has the recessed part 15a in the left side blower outlet 7b vicinity. The left shutter 20a in the closed state is fitted into the recess 15a. Similarly, a recess (not shown) that accommodates the right shutter 20b is also provided in the vicinity of the right side outlet 7c. Further, the recess 15a is configured such that the left shutter 20a and the right shutter 20b and the casing body 6 are arranged substantially continuously when the left shutter 20a and the right shutter 20b are in the closed state. For this reason, when the left shutter 20a and the right shutter 20b are in the closed state, the outer surfaces of the left shutter 20a and the right shutter 20b and the outer surface of the casing body 6 are arranged substantially in a single plane.

  6 (a) and 6 (b), the direction of the airflow when the conditioned air is sent forward using the horizontal flap 11 is indicated by a solid arrow, and the conditioned air is sent in the left-right direction. The direction of airflow is indicated by dotted arrows. FIG. 6A shows a state in which the left shutter 20a is closed and the left-side outlet 7b is closed, and a state where such an air flow shown by a solid line is generated, that is, the vertical louver 12 is shown. Shows a state perpendicular to the longitudinal direction. FIG. 6B shows a state in which the left shutter 20a is open and the left side outlet 7b is open, and a state in which such an air flow indicated by a dotted line is generated, that is, a vertical louver. 12 shows a state in which the surface of the 12 blades is tilted to the left from the direction perpendicular to the longitudinal direction. In the state of FIG. 6B, the conditioned air can be blown out in the direction in which the left side surface 2b of the casing body 6 faces using the horizontal flap 11 and the left side outlet 7b.

  As shown in FIG. 6, when the horizontal flap 11 is closed, the horizontal flap 11 exists on the flow line of the left shutter 20a. Therefore, when the left shutter 20a and the right shutter 20b are opened, the horizontal flap 11 is firstly opened. Opening operation is performed.

<Vertical louver tilt and shutter opening / closing>
The left shutter 20a and the right shutter 20b are selectively opened and closed according to the inclination of the vertical louver 12. FIG. 7 is a schematic diagram showing the relationship between the inclination of the vertical louver 12 and the opening / closing of the left shutter 20a and the right shutter 20b when the indoor unit 2 is viewed from the top surface 2d side. The vertical louver 12 is divided into a left louver 19a and a right louver 19b, connected to the connecting rods 13a and 13b, and driven separately.

  FIG. 7A shows a state in which the blade surface of the vertical louver 12 is in a state perpendicular to the longitudinal direction, and both the left shutter 20a and the right shutter 20b are closed. In the state of FIG. 7A, the conditioned air is blown out forward, and the conditioned air is not blown out in the left-right direction.

  FIG. 7B shows a state in which the blade surface of the vertical louver 12 is inclined rightward with respect to the longitudinal direction, the left shutter 20a is closed, and the right shutter 20b is opened. In the state of FIG. 7B, the left shutter 20a is closed in order to blow out conditioned air to the right.

  FIG. 7C shows a state in which the blade surface of the vertical louver 12 is inclined leftward with respect to the longitudinal direction, the left shutter 20a is opened, and the right shutter 20b is closed. In the state of FIG. 7B, the right shutter 20b is closed in order to blow out conditioned air to the left.

  In FIG. 7D, the blade surface of the left louver 19a of the vertical louver 12 is inclined to the left with respect to the longitudinal direction, and the blade surface of the right louver 19b is inclined to the left with respect to the longitudinal direction. The left shutter 20a and the right shutter 20b are shown open. In the state of FIG. 7 (d), both the left shutter 20a and the right shutter 20b are open in order to blow out conditioned air in both the left and right directions.

  FIG. 7E shows a state in which the blade surface of the vertical louver 12 swings left and right with a state perpendicular to the longitudinal direction as a boundary, and both the left shutter 20a and the right shutter 20b are closed. In the state of FIG. 7 (e), when the left shutter 20a and the right shutter 20b are opened and closed in correspondence with the blade surfaces of the vertical louver 12, the opening and closing operation continues in accordance with the swing, which makes the user uncomfortable. Because it gives, it is fixed in the closed state.

  7A to 7E, all the horizontal flaps 11 are open. In order to realize the states of FIGS. 7B to 7D, the horizontal flap 11 is opened as described above, and then the left shutter 20a and the right shutter 20b are opened.

  The relationship between the inclination of the vertical louver and the opening / closing of the shutter will be described with reference to FIG. 8A describes the relationship between the angle of the left louver 19a of the vertical louver 12 and the left shutter 20a, and FIG. 8B illustrates the angle of the right louver 19b of the vertical louver 12 and the right shutter. The relationship with 20b is described.

  As shown in FIG. 8 (a), there are angles 12p to 12u, 12x, and 12y as boundaries that the left louver 19a of the vertical louver 12 can take. The angle 12x is a left-side fully open angle. When the left louver 19a is at this angle, the structure hits and is an angle for determining the origin. The angle 12y is a right-side fully open angle. When the left louver 19a is at this angle, the structure hits and is an angle for determining the origin. The angle 12p is the left swing angle when the installation setting is in the center, the angle 12q is the right swing angle when the installation setting is in the center, and the angle 12p when the installation setting is in the center. And the left louver 19a swings in the range An1 between the angle 12q. The angle 12r is an angle at which the blade surface of the vertical louver 12 is perpendicular to the center, that is, the longitudinal direction of the indoor unit.

  The angle 12s is a left-side swing angle when the installation setting is left, and when the installation setting is left, the left louver 19a swings in a range An2 between the angle 12s and the angle 12q. The angle 12t is the right swing angle when the installation setting is right. When the installation setting is right, the left louver 19a swings in a range An3 between the angle 12p and the angle 12t. .

  The angle 12u is a boundary angle for determining whether the left shutter 20a is opened or closed. When the left louver 19a is in the range An4 between the angle 12u and the angle 12p, the left shutter 20a is opened, and the angle 12u is between the angle 12u and the angle 12q. When the left louver 19a is in the range An5, the left shutter 20a is closed.

  As shown in FIG. 8 (b), there are angles 12p to 12t, 12v, 12x, and 12y as boundaries that the vertical louver 12 can take. What is different from FIG. 8A is an angle 12v, which is a boundary angle for determining whether the right shutter 20b is opened or closed. When the right louver 19b is in the range An6 between the angle 12v and the angle 12p, the right shutter 20b is opened, and when the right louver 19b is in the range An7 between the angle 12u and the angle 12q, the right shutter 20b is closed.

<Horizontal flap>
FIG. 9 is a perspective view showing the appearance of the horizontal flap 11 and the surrounding structure. The horizontal flap 11 is suspended from a mounting plate 60 that forms the lower side of the indoor unit 2. The mounting plate 60 is disposed above the opening surface 16 of the central air outlet 7a so that the central air outlet 7a can be closed by the horizontal flap 11 attached to the mounting plate 60, and is guided forward of the air outlet passage 10. It arrange | positions at the surface 10d side.

  The left support arm drive unit 46 of the horizontal flap drive mechanism 41 includes a drive motor 54a as a drive source, and a pinion gear 52a is attached to the drive shaft 55a of the drive motor 54a. The pinion gear 52a meshes with the rack gear 56a at the opening 61a of the mounting plate 60, and the amount of protrusion of the left support arm 53a on which the rack gear 56a is formed is controlled by the rotational speed of the pinion gear 52a. For this purpose, a stepping motor is used as the drive motor 54a, the left support arm 53a is slidably inserted into the guide groove 62a, and the left support arm 53a moves into the guide groove 62a as the drive motor 54a rotates. Slide The tip of the left support arm 53a is pivotally supported by a rotation shaft 57a fixed to the connecting portion 11p of the horizontal flap 11.

  Similarly, the right support arm drive unit 47 includes a drive motor 54b as a drive source. As the drive motor 54b rotates, the right support arm 53b slides in the guide groove 62b, and the right support arm 53b The amount of protrusion is controlled by the number of rotations of the drive motor 54b. Note that the pinion gear of the right support arm drive unit 47 meshed with the opening 61b is not shown. The tip of the right support arm 53b is also pivotally supported by a rotation shaft (not shown) fixed to the connecting portion 11q of the horizontal flap 11.

  The intermediate support arm drive unit 48 includes a drive motor 54c as a drive source. The drive motor 54c is attached to the rotating arm 58a of the intermediate support arm 53c in order to drive the intermediate support arm 53c. The rotating arm 58a is connected to the swing arm 58b by a movable shaft (not shown) (see FIG. 10C). The swing arm 58b is pivotally supported at the connecting portion 11r of the horizontal flap 11 so as to be swingable. The horizontal flap 11 is mainly rotated by rotating the swing arm 58b around the rotation axis of the drive motor 54c.

  FIG. 10 is a view schematically showing a cross section in the vicinity of the air outlet as viewed from the side surface in order to explain the operation of the horizontal flap. FIG. 10A shows a state when the operation of the air conditioner 1 is stopped and the horizontal flap 11 is fully closed. At this time, the left support arm 53a and the right support arm 53b are stored so that the amount of protrusion is minimized within a range in which the horizontal flap 11 can move smoothly. In order to house the left support arm 53a, the drive motor 54a drives the pinion gear 52a to rotate counterclockwise as viewed from the right to retract the left support arm 53a. In order to house the right support arm 53b, the drive motor 54b is driven to rotate the pinion gear counterclockwise as viewed from the right to retract the right support arm 53b. At that time, the driving motor 54c rotates the pivot arm 58a counterclockwise as viewed from the right to pull up the swing arm 58b and lift the rear end side of the horizontal flap 11 upward. Each of the drive motors 54a, 54b, 54c continues to generate a drive force even after the horizontal flap 11 contacts the casing body 6. However, since the horizontal flap 11 is in contact with the casing body 6, the rack gears 56a and 56b and the rotating arm 58a do not move. In this way, the tightening is a process in which the driving motors 54a, 54b, 54c generate a driving force even after the rack gears 56a, 56b and the rotating arm 58a do not move. By performing such tightening, the central air outlet 7a can be reliably closed by the horizontal flap 11.

  FIG. 10B shows a state in which the horizontal flap 11 is most rotated clockwise as viewed from the right after the horizontal flap 11 is opened. In the following description, a state in which the horizontal flap 11 is rotated most clockwise is referred to as a roll-up state. In order to be in the roll-up state, the left support arm 53a and the right support arm 53b must protrude to the point where the horizontal flap 11 does not hit the casing body 6 even in the roll-up state. In the state shown in FIG. 10B, the left support arm 53a and the right support arm 53b are pushed out until the horizontal flap 11 does not hit the casing body 6, but the amount of the push is reduced as much as possible. State. In the following description, a state in which the amount of protrusion of the left support arm 53a and the right support arm 53b is minimized as long as the horizontal flap 11 does not hit the casing body 6 in any posture is referred to as an arm upper position. In this arm upper position, the horizontal flap 11 does not contact the casing body 6 at any angle of the horizontal flap 11. In the roll-up state, the movable part other than the horizontal flap 11 hits any part and causes the structure to stop moving any more. When such a structural hit occurs, the horizontal flap 11 shown in FIG. 10A is tightened to position the horizontal flap 11, and in the case of FIG. 10B, the rotation angle of the horizontal flap 11 is determined. Criteria can be given.

  FIG. 10C shows a state in which the horizontal flap 11 is most rotated counterclockwise when viewed from the right at the upper arm position. In the following description, the state in which the horizontal flap 11 is most rotated counterclockwise is referred to as a roll-down state. In order to enter the roll-down state, the left support arm 53a and the right support arm 53b must protrude until the horizontal flap 11 does not hit the casing body 6 even in the roll-down state. Even in the roll-down state, the movable part other than the horizontal flap 11 hits any part and causes a structure hit that does not move any more. The horizontal flap 11 can be positioned by retightening when such a structural hit occurs, and the reference of the rotation angle of the horizontal flap 11 can be given in the same manner as in FIG. Therefore, the control unit 30 can accurately control the rotational angle of the horizontal flap 11 using either or both of FIG. 10B and FIG. 10C.

  FIG. 10 (d) shows the state of the horizontal flap during operation at the arm upper position. When operating in the roll-up state of FIG. 10 (b) or the roll-down state of FIG. 10 (c), the structure hits and deteriorates quickly due to the influence of vibration or the like. Driving is performed using an angle between the angle rotated slightly counterclockwise and the angle rotated slightly clockwise than the roll-down state.

  FIG. 10E shows a state (rolled-down state) in which the horizontal flap 11 is most rotated counterclockwise as viewed from the right after the horizontal flap 11 is opened. In the state shown in FIG. 10 (e), the left support arm 53a and the right support arm 53b are pushed out until the horizontal flap 11 does not hit the casing body 6, but the amount of the push out is increased as much as possible. State. In the following description, the state in which the amount of protrusion of the left support arm 53a and the right support arm 53b is maximum is referred to as an arm lower position. In this arm lower position, the horizontal flap 11 does not contact the casing body 6 at any angle of the horizontal flap 11. In the roll-down state, the movable part other than the horizontal flap 11 hits any part and causes a structure hit that does not move any more. Therefore, the horizontal flap 11 can be positioned by tightening when it is raised, and the reference of the rotation angle of the horizontal flap 11 can be given also in the case of FIG. It is possible to accurately control the rotational angle of the horizontal flap 11 by using (e).

  At the lower arm position, the amount of protrusion of the left support arm 53a and the right support arm 53b is maximized. Therefore, when the length of the horizontal flap 11 is added to the left support arm 53a and the right support arm 53b, The possibility of the horizontal flap 11 hitting the furniture to be arranged increases. Therefore, the roll-up state is prohibited at the arm lower position.

  FIG. 10F shows the state of the horizontal flap during operation at the arm lower position. When operating in the roll-down state of FIG. 10 (e), the structure hits and deteriorates quickly due to the influence of vibration, etc., so use an angle rotated slightly clockwise than the roll-down state. Driving is performed.

<Control unit>
By adjusting the blowing direction of the horizontal flap 11 and the vertical louver 12 as described above, adjusting the wind speed of the cross flow fan 9, and opening and closing the left shutter 20a and the right shutter 20b, it is possible to appropriately adapt to the indoor form and the indoor situation. A conditioned air flow for air conditioning can be generated. That is, the horizontal flap 11, the vertical louver 12, the cross flow fan 9, the left shutter 20a and the right shutter 20b, and a mechanism for driving them constitute an airflow adjusting device. In order to control the airflow control device including the horizontal flap 11, the vertical louver 12, the cross flow fan 9, the left shutter 20a and the right shutter 20b, a control unit 30 as shown in FIG. 11 is provided.

  The control unit 30 includes an indoor control unit 31 for controlling each device of the indoor unit 2 and an outdoor control unit 32 for controlling each device of the outdoor unit, and the indoor control unit 31 and the outdoor control unit. 32 is connected by a signal line 33.

  The outdoor control unit 32 is connected to a compressor 34, an outdoor electric expansion valve 35, a four-way switching valve 36, an outdoor fan 37, a plurality of pressure sensors 38, a plurality of temperature sensors 39, and the like. The outdoor control unit 32 controls the operation switching such as switching between the heating operation and the cooling operation by switching the circulation path of the refrigerant flowing through the refrigeration circuit by switching the four-way switching valve 36. The outdoor control unit 32 controls, for example, the refrigerant circulation amount of the refrigerant circuit by controlling the rotation speed of the compressor 34, and controls the pressure of the refrigerant flowing through the refrigerant circuit by controlling the opening degree of the outdoor electric expansion valve 35. To do. The outdoor control unit 32 controls the heat exchange efficiency in the outdoor heat exchanger by controlling the rotational speed of the outdoor fan 37. Therefore, the outdoor control unit 32 uses the temperature and pressure of each part detected by a plurality of pressure sensors 38 and temperature sensors 39 installed in the refrigerant circuit and each device for judgment for control.

  On the other hand, the indoor control unit 31 is connected to a transmission / reception unit 40, a horizontal flap drive mechanism 41, a vertical louver drive mechanism 42, a shutter drive mechanism 49, a crossflow fan motor 43, a temperature sensor 44, a display unit 45, and the like. . The indoor control unit 31 transmits and receives data between the user's remote controller 5 and the transmission / reception unit 40 for control. The indoor control unit 31 controls the horizontal flap drive mechanism 41, the vertical louver drive mechanism 42, and the crossflow fan motor 43 in accordance with the indoor state and the user's settings, and the angle and swing of the horizontal flap 11 and the vertical louver 12 are controlled. The state of movement and the rotational speed of the motor 43 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 31 uses state information such as the temperature of each part detected by a plurality of temperature sensors 44 installed in the refrigerant circuit and each device for judgment for control. Further, the indoor control unit 31 notifies the user of the setting state and environment of the indoor unit 2 via the display unit 45.

  The horizontal flap drive mechanism 41 controlled by the indoor control unit 31 drives the left support arm drive unit 46, the right support arm drive unit 47, and the intermediate support arm so that the horizontal flap 11 can be driven out and stored. A portion 48 is provided. The indoor control unit 31 controls the movement amount of the left support arm 53a and the movement amount of the right support arm 53b to be the same when moving the horizontal flap 11 in parallel, so that the horizontal flap 11 moves in parallel. The intermediate support arm 53c is caused to follow the movement of the left support arm 53a and the right support arm 53b.

  When the horizontal flap 11 is released from the state in which the air outlet 7 is blocked, and the horizontal flap 11 is brought into a desired state, the indoor control unit 31 first performs the left support arm drive unit 46 and the right support arm drive unit 47 to the left. The support arm 53a and the right support arm 53b are driven. The air outlet 7 that has been blocked by the ejection of the horizontal flap 11 is opened. At this time, the intermediate support arm driving unit 48 operates to eject the horizontal flap 11 against the opening surface 16 of the central air outlet 7a. Following this, the rotating arm 58a is rotated. Thereby, the horizontal flap 11 is smoothly opened from the air outlet 7 without being rubbed strongly around the air outlet 7. Since it has the mechanism moved in this way, the shape of the horizontal flap 11 can be made substantially equal to the shape of the central outlet 7a. Therefore, the gap 2w (see FIG. 2) when the central air outlet 7a is blocked by the horizontal flap 11 can be reduced. Thereby, the designability can be improved. Further, for example, as shown in FIG. 3, the lower surfaces 2x, 2y, 2z of the indoor unit 2 can be flush with each other, and the boundary between the horizontal flap 11 and the surrounding casing body 6 is made inconspicuous. Thus, a beautiful appearance can be formed.

  Next, the left support arm 53a and the right support arm 53b are fixed, and the intermediate support arm driving unit 48 rotates the rotation arm 58a to connect the left support arm 53a and the right support arm 53b. The horizontal flap 11 is rotated around an axis connecting the connecting portion. The horizontal flap 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 31 performs control so that the horizontal flap 11 is moved to a desired state in one step by performing the two-step operation as described above in parallel and performing the rotational movement while performing the parallel movement. You can also

  The operations of the intermediate support arm 53c, the left support arm 53a and the right support arm 53b and the specific posture control of the horizontal flap 11 will be described later.

  The shutter drive mechanism 49 is a mechanism for driving the left shutter 20a and the right shutter 20b, and includes a shutter drive mechanism drive motor and a shutter drive arm, which will be described later. The controller 30 controls the opening and closing of the left shutter 20a and the right shutter 20b by controlling the driving of the shutter drive mechanism 49. The left and right shutters 20a and 20b can be opened and closed independently by the shutter drive mechanism 49, and can be controlled by the control unit 30 independently.

<Remote controller>

[Fig. 11] is a screen display showing a selection result of a wind area. Here, the wind area is an area where conditioned air blown from the indoor unit 2 is directly blown. In this embodiment, the room is divided into the center and the left and right sides in the longitudinal direction of the indoor unit 2, and the areas to be blown directly are all areas including the center and both left and right sides, and the left including the center and the left side. It is divided into three areas: the area and the right area including the center and the right side. FIG. 12A shows a display screen when all areas are selected, FIG. 12B shows a display screen when the right area is selected, and FIG. The display screen when the left area is selected is shown.

  In order to display the liquid crystal screen as shown in FIG. 12A, a menu that allows selection of the wind area is selected by the menu / decision button 5n. The mode selection in the wind area menu is performed by the wind area button 5m. The entire area of FIG. 12A, the right area of FIG. 12B, and the left area of FIG. 12C are cyclically switched and can be selected every time the wind area button 5m is pressed.

<Installation position setting and LCD display>
The wall-mounted indoor unit 2 in FIG. 1 is not always installed at the center of the wall W of the room, and may be installed near the left end or the right end of the wall W. If the indoor unit 2 is installed near the right end or the left end of the wall W, the distance between the adjacent wall following the wall W and the indoor unit 2 is too close, and depending on the direction in which the conditioned air blows out, The conditioned air will be blown toward you. If the conditioned air directly hits a wall or furniture arranged near the wall, it is not preferable because condensation or dust winding occurs. Therefore, an installation position setting mode is provided in which the direction in which the conditioned air is blown out is limited depending on the installation position of the indoor unit 2.

  As shown in FIG. 8, when the indoor unit 2 is installed at the right end of the wall W and the right installation position is set, the indoor unit 2 adjusts the angle of the vertical louver 12 up to the right swing angle 12t. . When the indoor unit 2 is installed at the left end of the wall W and the left installation position is set, the indoor unit 2 adjusts the angle of the vertical louver 12 up to the left swing angle 12s.

  FIG. 14 shows the relationship among the liquid crystal display of the remote controller, the up / down air direction, the left and right shutters, the left / right air direction, and the air-conditioning area when the installation position is set to the center.

  In FIG. 14, the first row in which the screen display composed of characters of all areas and three arrows is drawn as a liquid crystal display shows a state in which all areas are selected as the wind area. When all areas are selected as the wind area, a screen composed of characters of all areas and three arrows is displayed on the liquid crystal display portion 5a of the remote controller 5. In the indoor unit 2 in which all areas are selected, the up and down wind direction follows the operation mode, the left shutter 20a and the right shutter 20b are opened, and the left and right wind directions are adjusted so that the left louver 19a is adjusted to the left swing angle 12p, and the right louver 19b is on the right side. The swing angle is adjusted to 12q. Therefore, the area indicated by hatching in the lowermost row in the first row in FIG. 14 is an air conditioning area, and the conditioned air flow blown out by the indoor unit 2 covers the entire range of the room 100.

  In FIG. 14, the second column in which a screen display composed of characters in the right area and two arrows is drawn shows the state when the right area is selected as the wind area. When the right area is selected as the wind area, a screen composed of characters in the right area and two arrows is displayed on the liquid crystal display unit 5a of the remote controller 5. In the indoor unit 2 in which the right area is selected, the vertical wind direction adjusted by the horizontal flap 11 follows the operation mode, the left shutter 20a is closed and the right shutter 20b is opened, and the left and right wind directions are the left louver 19a and the right louver 19b. The right swing angle is adjusted to 12q. Therefore, the air conditioning area is limited to the center and the right side of the room 100 as indicated by hatching in the lowermost row of the second row in FIG.

  In FIG. 14, a third column in which a screen display composed of characters in the left area and two arrows is drawn shows a state when the left area is selected as the wind area. That is, when the left area is selected as the wind area, a screen composed of the characters in the left area and the two arrows is displayed on the liquid crystal display unit 5a of the remote controller 5. In the indoor unit 2 in which the left area is selected, the vertical wind direction adjusted by the horizontal flap 11 follows the operation mode, the left shutter 20a is opened and the right shutter 20b is closed, and the left and right wind directions are the left louver 19a and the right louver 19b. The left swing angle is adjusted to 12p. Therefore, the airflow of the conditioned air blown out from the air-conditioning area, that is, the indoor unit 2 is limited to the center and the left side of the room 100 as shown by hatching in the lowermost row of the second row in FIG.

  As described above, when the installation position is set to the center, three types of modes can be selected as the wind area: the entire area, the right area, and the left area. Accordingly, three types of screen display are possible on the liquid crystal display unit 5 a of the remote controller 5, and three types of modes can be input using the operation unit 5 b of the remote controller 5.

  However, as described above, since there is a mode for setting the installation position that restricts the direction in which the conditioned air is blown out depending on the installation position of the indoor unit 2, for example, if the installation position setting is set to the left corner, the left side of FIG. An angle toward the left is allowed only up to a swing angle of 12 s, and the left area of the wind area of the vertical louver 12 cannot be set.

  FIG. 15 shows the relationship among the liquid crystal display of the remote controller, the up / down air direction, the left and right shutters, the left / right air direction, and the air conditioning area when the installation position is set to the left side.

  In FIG. 15, the first column shows the state when all areas are selected as the wind area, and the liquid crystal display unit 5a of the remote controller 5 includes characters of all areas and three arrows. A screen is displayed. In this case, in the indoor unit 2, the vertical wind direction adjusted by the horizontal flap 11 follows the operation mode, the left shutter 20a is closed and the right shutter 20b is opened, and the left and right wind directions are adjusted so that the left louver 19a is adjusted to the center angle 12r. The right louver 19b is adjusted to the right swing angle 12q. Therefore, the flow of conditioned air blown out by the indoor unit 2 is limited to the front and right sides of the indoor unit 2. However, since the indoor unit 2 is installed at the left corner of the wall W, as indicated by hatching in the bottom row of the first row in FIG. Spans the entire range.

  In FIG. 15, the second column shows the state when the right area is selected as the wind area, and the liquid crystal display unit 5a of the remote controller 5 is composed of characters in the right area and two arrows. A screen is displayed. In this case, the up and down wind direction adjusted by the horizontal flap 11 follows the operation mode, the left shutter 20a is closed and the right shutter 20b is opened, and the left and right wind directions are the left louver 19a and the right louver 19b at the right swing angle 12q. Adjusted. Therefore, the flow of conditioned air blown out by the indoor unit 2 is approximately the center of the room 100 and the flow of conditioned air blown out by the indoor unit 2 as shown by hatching in the bottom row of the second row in FIG. Limited to the right side. Since the indoor unit 2 is installed in the left corner of the wall W, a little conditioned air flow is generated in front of the indoor unit 2 near the indoor unit 2, so that it is limited to the right side here. is doing.

  In FIG. 15, the third row is erased with a cross. This indicates that the left area cannot be selected as the wind area. When the installation position is set to the left corner, two types of modes can be selected as the wind area: the entire area and the right area. That is, the input is limited to two types of modes using the operation unit 5b of the remote controller 5, and the display on the liquid crystal display unit 5a of the remote controller 5 is also limited to two types. The method of limiting the mode selection in the indoor unit 2 and the screen display and input limitation by the remote controller 5 will be described later.

  FIG. 16 shows the relationship between the liquid crystal display of the remote controller 5, the up and down air direction, the left and right shutters, the left and right air directions, and the air conditioning area when the installation position setting is right corner.

  In FIG. 16, the first row shows the state when all areas are selected as the wind area, and the liquid crystal display unit 5 a of the remote controller 5 includes characters of all areas and three arrows. A screen is displayed.

<Wind area and liquid crystal display restriction method>
FIG. 17 shows the CPU 31a, the storage unit 31b, and the transmission / reception unit 40 of the indoor unit 2 extracted from the control unit 30 shown in FIG. The storage unit 31b on the indoor unit 2 side stores a vertical louver driving application AP1 for driving the vertical louver 12 and a side shutter driving application AP2. The vertical louver drive application AP1 includes a center subprogram P1, a right corner subprogram P2, and a left corner subprogram P3. The side shutter drive application AP2 also includes a center subprogram P4, a right corner subprogram P5, and a left corner subprogram P6.

  Further, as shown in FIG. 13B, the storage area 5d of the remote controller 5 stores a wind area setting application AP3, which includes the installation position central subprogram Sub1 and the installation position right corner. A subprogram Sub2 and an installation position left corner subprogram Sub3 are included.

  The screen display of the liquid crystal display unit 5a shown in FIG. 14 and the control of the remote controller 5 are described in the installation position center subprogram Sub1, the control of the vertical louver 12 is described in the center subprogram P1, and the left shutter 20a Control of the right shutter 20b is described in the central subprogram P4.

  Further, the screen display of the liquid crystal display unit 5a shown in FIG. 15 and the control of the remote controller 5 are described in the installation position right corner subprogram Sub2, and the control of the vertical louver 12 is described in the right corner subprogram P2. The control of the left shutter 20a and the right shutter 20b is described in the right corner subprogram P5.

  Further, the screen display of the liquid crystal display unit 5a shown in FIG. 16 and the control of the remote controller 5 are described in the installation position left corner subprogram Sub3, and the control of the vertical louver 12 is described in the left corner subprogram P3. Control of the left shutter 20a and the right shutter 20b is described in the left corner subprogram P6.

  As shown in the flowchart of FIG. 18, the installation position setting mode is selected using the menu / decision button 5n of the remote controller 5 as shown in the screen display of the liquid crystal display unit 5a of FIG. Although not shown, the center, right corner, and left corner are displayed on the liquid crystal display unit 5a by the selection button 5p, and the installation position is set by the menu / decision button 5n. When the installation position is set using this installation position setting mode, the command is transmitted from the transmission / reception unit 5e of the remote controller 5 to the CPU 31a via the transmission / reception unit 40. CPU31a memorize | stores the content of the instruction | command in the memory | storage part 31b (step S1).

  When the installation position is set on the remote controller 5 side, switching to a subprogram corresponding to the installation position is performed (step S2). For example, when the right corner is selected as the installation position, the CPU 5c reads the installation position right corner subprogram Sub2 from the storage unit 5d in parallel with the transmission of the command from the transmission / reception unit 5e.

  On the indoor unit 2 side, for the vertical louver drive application AP1, switching of the subprogram corresponding to the installation position set by the CPU 31a is performed.
