More specifically, as an assembling procedure, after the front panel 4 is assembled into the indoor unit body 2, the front panel 4 is opened at a certain angle, and the front end convex portion 64 b of the protective cover 64 is provided on the front frame 3. It is inserted into the receiving portion 3d and fixed with a screw 66. With this configuration, the driver 82 can be used from an obliquely downward direction, and the work can be easily performed.

  On the other hand, in the present embodiment, as described above, each sensor unit 26, 28, 30, 32, 34 is provided on the front panel 4, so when the front panel 4 opens the front opening 2a. It moves along with the front panel 4 and protrudes further forward.

  The sensor unit 26 includes a circuit board 26a, a lens 26b attached to the circuit board 26a, and a human body detection sensor (not shown) mounted inside the lens 26b. The same applies to the other sensor units 28, 30, 32, and 34. That is, the other sensor units 28, 30, 32, and 34 are also circuit boards 28a, 30a, 32a, and 34a, and lenses 28b, 30b, 32b, and 34b attached to the circuit boards 28a, 30a, 32a, and 34a, respectively. , And a human body detection sensor (not shown) mounted inside the lenses 28b, 30b, 32b, and 34b. Furthermore, the human body detection sensor is configured by, for example, an infrared sensor that detects the presence or absence of a person by detecting infrared radiation emitted from the human body, and a pulse that is output in response to a change in the amount of infrared detected by the infrared sensor. Based on the signal, the presence or absence of a person is determined by the circuit boards 26a, 28a, 30a, 32a, and 34a. That is, the circuit boards 26a, 28a, 30a, 32a, and 34a function as presence / absence determining means for determining the presence / absence of a person. Hereinafter, a sensor and a lens paired with each other are referred to as a sensor / lens pair.

  Here, in order to obtain the detection areas in the front and rear, right and left directions, it is conceivable to arrange the sensor units 26, 28, 30, 32 and 34 on the surface of an arbitrary sphere Z as shown in the side view of FIG. . In this case, the optical axes of the sensor / lens pairs of the sensor units 26, 28, 30, 32, and 34 intersect at the center P of the sphere Z and are not in a twisted position. When viewed from the indoor unit, the sensor units 26, 28, 30, 32, and 34 are projected on the surface of the sphere Z in the front-rear direction, so it is difficult to reduce the size of the human body detection device.

  Further, in order to prevent the sensor unit from jumping out as described above, an arbitrary sphere Z is cut out at an arbitrary plane X as shown in FIG. 7, and the optical axis of the plane X and each of the sensor units 26, 28, 30, 32, and 34 is cut. It is also conceivable to arrange each sensor unit 26, 28, 30, 32, 34 at the intersection with (not the twist position). In this case, the arrangement of the sensor units 26, 28, 30, 32, and 34 is less likely to jump out in the front-rear direction as shown in the front view of FIG. The arrangement of sensor units having different distances from each other is dispersed in the vertical and horizontal directions, and there is a limit to downsizing the human body detection device.

  Therefore, in the present embodiment, the optical axes of the sensor / lens pair of the sensor units 26, 28 are on the same plane, and the optical axes of the sensor / lens pair of the sensor units 30, 32, 34 are on the same plane. However, the optical axis of the sensor / lens pair of the sensor units 26 and 28 and the optical axis of the sensor / lens pair of the sensor units 30, 32, and 34 are not on the same plane, but are twisted. Each circuit board 26a, 28a, 30a, 32a, 34a is attached to the sensor holder 36 at a predetermined angle.

  Thus, by setting the optical axis of the sensor / lens pair of the sensor unit having a different distance between the detection area and the indoor unit to the twisted position, as shown in FIGS. 1 and 2, the sensor units 26, 28, 30, 32 and 34 can be arranged substantially linearly in the lateral direction, and the human body detection device can be downsized.

  Although an example in which sensor units having different distances from the indoor unit to the detection area of the sensor unit are arranged in a substantially straight line in the lateral direction has been described, sensor units having different left and right directions are substantially straight in the height direction of the indoor unit. The same can be said for the case of the arrangement.

  As described above, according to the present embodiment, among the plurality of sensor units 26, 28, 30, 32, and 34 provided in the indoor unit, sensors having different distances between the visual field area of the sensor unit and the air conditioner Since the optical axes of the sensor / lens pair of the unit are twisted with respect to each other, the sensor units 26, 28, 30, 32, and 34 can be installed so as not to jump out of the front panel 4 of the indoor unit. The human body detection device can be downsized.

  Further, by arranging the sensor units 26, 28, 30, 32, 34 in a substantially straight line, the sensor units 26, 28, 30, 32, 34 are not dispersed in the vertical and horizontal directions, and the sensor units 26, 28, The size of 30, 32, 34 can be reduced.

  In addition, a plurality of sensor units 26, 28, 30, 32, and 34 in which the optical axes of the sensor / lens pairs are twisted as described above are provided as human body detecting devices, and the optical axes of the sensor / lens pairs are arranged in the visual field direction. Since it is arranged so as to face, it is possible to form a plurality of detection areas in the distance direction and a plurality of detection areas in the left-right direction when viewed from the human body detection device, and downsize the lens by improving the light collection efficiency Is possible.

  FIG. 9 shows human body position determination areas detected by the sensor units 26, 28, 30, 32, and 34. The sensor units 26, 28, 30, 32, and 34 each have a person in the next area. Can be detected.

Sensor unit 26: area A + C + D
Sensor unit 28: Area B + E + F
Sensor unit 30: area C + G
Sensor unit 32: Area D + E + H
Sensor unit 34: area F + I
That is, in the indoor unit of the air conditioner according to the embodiment of the present invention, the area that can be detected by the sensor units 26 and 28 partially overlaps the area that can be detected by the sensor units 30, 32, and 34. The number of sensor units smaller than the number of A to I is used to detect the presence or absence of a person in each of the areas A to I.

  In addition, by attaching at least three human body detection sensors to the upper part of the indoor unit, the position of the human body in the room can be two-dimensionally grasped in the perspective direction and the horizontal direction with respect to the indoor unit, that is, where on the indoor floor. Can do. FIG. 10 shows an area to be detected when three human body detection sensors are provided. In the example of FIG. 10, the presence or absence of a person in the area near the indoor unit is detected by one human body detection sensor. The presence or absence of a person in an area far from the machine is detected by two human body detection sensors.

  Returning to FIG. 9, this embodiment will be further described. In the following description, the sensor units 26, 28, 30, 32, and 34 are replaced with the first sensor 26, the second sensor 28, the third sensor 30, 4 sensors 32 and a fifth sensor 34. Since the areas C, D, E, and F are detected by two sensors, the areas other than the overlapping areas (areas A, B, G, H, and I) are detected by one sensor. Therefore, it is called a normal area. The overlapping area is divided into left overlapping areas C and D and right overlapping areas E and F.

  FIG. 11 is a flowchart for setting region characteristics to be described later in each of the regions A to I using the first to fifth sensors 26, 28, 30, 32, and 34. FIG. FIG. 11 is a flowchart for determining which area of the areas A to I is used by using the fifth sensors 26, 28, 30, 32, and 34, and determining the position of the person with reference to these flowcharts. The method will be described below.

  In step S1, the presence or absence of a person in the left overlapping region is first determined at a predetermined period T1 (for example, 5 seconds), and in step S2, a predetermined sensor output is cleared under a predetermined condition.

  Table 1 shows a method of determining the left overlapping region. When one of the three reaction results shown in Table 1 is satisfied, the outputs of the first sensor 26 and the third sensor 30 are cleared. . Here, 1 is defined as a response, 0 is defined as no response, and clear is defined as 1 → 0.

  In step S3, the presence / absence of a person in the right overlapping region is further determined in the above-described predetermined period T1, and in step S4, a predetermined sensor output is cleared under a predetermined condition.

  Table 2 shows a method for determining the right overlapping region. When one of the three reaction results shown in Table 2 is satisfied, the outputs of the second sensor 28 and the fifth sensor 34 are cleared. .

  Moreover, when it corresponds to either of the six reaction results shown in Table 1 and Table 2, the output of the 4th sensor 32 is also cleared and it transfers to step S5. In step S5, the presence / absence of a person in the normal region is determined based on Table 3 in the above-described predetermined cycle T1, and in step S6, all sensor outputs are cleared.

  Further, a case where the presence / absence of a person in the areas A, B, and C is determined using only the outputs from the first to third sensors 26, 28, and 30 will be described with reference to FIG.

  As shown in FIG. 13, when all of the first to third sensors 26, 28, and 30 are OFF (no pulse) in the period T1 immediately before the time t1, there are people in the regions A, B, and C at the time t1. It is determined that there is no yes (A = 0, B = 0, C = 0). Next, during the period from time t1 to time t2 after period T1, only the first sensor 26 outputs an ON signal (with a pulse), and when the second and third sensors 28, 30 are OFF, at time t2. It is determined that there is a person in the area A and there are no persons in the areas B and C (A = 1, B = 0, C = 0). Further, when the first and third sensors 26 and 30 output the ON signal from the time t2 to the time t3 after the period T1, and the second sensor 28 is OFF, a person is in the region C at the time t3. It is determined that there are no people in the areas A and B (A = 0, B = 0, C = 1). Hereinafter, the presence / absence of a person in each of the areas A, B, and C is similarly determined for each period T1.

Actually, the first to fifth sensors 26, 28, 30, 32, and 34 are used to determine in which area of the areas A to I a person is present. Based on each of the areas A to I, a first area where the person is good (a place where the person is good), a second area where the time where the person is short is short (an area where the person simply passes, an area where the stay time is short, etc. ), And a third area (a non-living area such as a wall or a window where people hardly go) is distinguished. Hereinafter, the first region, the second region, and the third region are referred to as a life category I, a life category II, and a life category III, respectively, and the life category I, the life category II, and the life category III are respectively a region characteristic I. It can also be said that the region of region characteristic II, region of region characteristic II, region of region characteristic III. Further, the life category I (region characteristic I) and the life category II (region characteristic II) are combined into a life region (region where people live), while the life category III (region characteristic III) is changed to a non-life region ( The area of life may be broadly classified according to the frequency of the presence or absence of a person.

  This determination is performed after step S7 in the flowchart of FIG. 11, and this determination method will be described with reference to FIGS.

  FIG. 14 shows a case where the indoor unit of the air conditioner according to the embodiment of the present invention is installed in an LD of 1 LDK composed of one Japanese-style room, LD (living room / dining room) and kitchen. The area indicated by the ellipse in is a well-placed place declared by the subject.

  As described above, the presence / absence of a person in each of the areas A to I is determined every period T1, and 1 (with a reaction) or 0 (without a reaction) is output as a reaction result (determination) in the period T1. Is repeated a plurality of times, and in step S7, it is determined whether or not a predetermined operating time of the air conditioner has elapsed. If it is determined in step S7 that the predetermined time has not elapsed, the process returns to step S1. On the other hand, if it is determined that the predetermined time has elapsed, two reaction results accumulated in the predetermined time in each region A to I are obtained. By comparing with the threshold value, each of the areas A to I is determined as one of the life categories I to III.

  In more detail with reference to FIG. 15 showing the long-term accumulation result, the first threshold value and the second threshold value smaller than the first threshold value are set, and in step S8, the long-term accumulation result of each region A to I is set. Is determined to be greater than the first threshold, and the region determined to be greater is determined to be the life category I in step S9. If it is determined in step S8 that the long-term cumulative result of each region A to I is less than the first threshold value, whether or not the long-term cumulative result of each region A to I is greater than the second threshold value in step S10. The region determined to be large is determined to be the life category II in step S11, while the region determined to be small is determined to be the life category III in step S12.

  In the example of FIG. 15, the areas E, F, and I are determined as the life category I, the areas B and H are determined as the life category II, and the areas A, C, D, and G are determined as the life category III.

  FIG. 16 shows a case where the indoor unit of the air conditioner according to the embodiment of the present invention is installed in another 1 LDK LD. FIG. 17 shows each region A based on the long-term accumulation result in this case. The result of discriminating ~ I is shown. In the example of FIG. 16, the areas C, E, and G are determined as the life category I, the areas A, B, D, and H are determined as the life category II, and the areas F and I are determined as the life category III.

  Note that the above-described determination of the region characteristics (life classification) is repeated every predetermined time, but the determination result hardly changes unless the sofa, the table, or the like arranged in the room to be determined is moved.

  Next, the final determination of the presence / absence of a person in each of the areas A to I will be described with reference to the flowchart of FIG.

Since steps S21 to S26 are the same as steps S1 to S6 in the flowchart of FIG. 11 described above, the description thereof is omitted. In step S27, it is determined whether or not a predetermined number M (for example, 15 times) of reaction results in the period T1 has been obtained. If it is determined that the period T1 has not reached the predetermined number M, the process returns to step S21. If it is determined that the period T1 has reached the predetermined number M, in step S28, the total number of reaction results in the period T1 × M is used as the cumulative reaction period number, and the cumulative reaction period number for one time is calculated. The calculation of the cumulative reaction period is repeated a plurality of times, and it is determined in step S29 whether or not the calculation result of the cumulative reaction period is obtained for a predetermined number of times (for example, N = 4). When the determination is made, the process returns to step S21. On the other hand, when it is determined that the predetermined number of times has been reached, in step S30, the person in each of the areas A to I is determined based on the already determined area characteristics and the predetermined number of accumulated reaction periods. Presence or absence of is estimated.

  In step S31, by subtracting 1 from the calculation number (N) of the cumulative reaction period number and returning to step S21, the calculation of the cumulative reaction period number of times is repeated.

  Table 4 shows a history of reaction results for the latest one time (time T1 × M). In Table 4, for example, ΣA0 means the number of cumulative reaction periods for one time in the region A.

  Here, the cumulative reaction period number of one time immediately before ΣA0 is ΣA1, the previous cumulative reaction period number of ΣA2 is ΣA2,... Presence or absence of a person is estimated from the life category and the cumulative number of reaction periods.

  Next, after the time T1 × M from the above-described determination of the presence / absence of the person, the presence / absence of the person is similarly estimated from the past four histories, life categories, and cumulative reaction period times.

  That is, in the indoor unit of the air conditioner according to the embodiment of the present invention, since the presence / absence of a person is estimated by using a smaller number of sensors than the number of the discrimination areas A to I, every predetermined period. In this estimation, the position of a person may be mistaken.Therefore, regardless of whether it is an overlapping area or not, it is avoided to estimate the position of a person in a single predetermined period. By accumulating the area determination results for each predetermined period N times, and estimating the person's location from the past history of the accumulated reaction period times of each area obtained, the position estimation result of the person with high probability is obtained. Yes.

  Table 5 shows the time required for the presence estimation and the time required for the absence estimation when the presence / absence of the person is determined as described above and T1 = 5 seconds and M = 12 times are set.

Thus, the area to be air-conditioned by the indoor unit of the air conditioner according to the embodiment of the present invention is divided into a plurality of areas A to by the first to fifth sensors 26, 28, 30, 32 and 34. After being divided into I, the region characteristics (life categories I to III) of the respective regions A to I are determined, and the time required for the presence estimation and the time required for the absence estimation are further determined according to the region characteristics of the respective regions A to I. I am trying to change each.

  In other words, after changing the air conditioning setting, it takes about 1 minute for the wind to reach. Therefore, even if the air conditioning setting is changed in a short time (for example, several seconds), not only the comfort is impaired, but the person is quick. It is preferable not to air-condition the place where it disappears from the viewpoint of energy saving. Therefore, the presence or absence of a person in each of the areas A to I is first detected, and in particular, the air conditioning setting in the area where the person is present is optimized.

  More specifically, with the time required for estimating the presence / absence of the area determined as the life category II as a standard, in the area determined as the life category I, there is a person at a shorter time interval than the area determined as the life category II. In contrast, when there are no people in the area, the absence of the person is estimated at a longer time interval than the area determined as the life category II. The time required for estimation is set to be long. On the other hand, in the area determined to be life category III, the presence of a person is estimated at a longer time interval than the area determined to be life category II. By estimating the absence of a person at a time interval shorter than the region determined as II, the time required for the presence estimation is set longer and the time required for the absence estimation is set shorter. Furthermore, as described above, the life division of each region changes depending on the long-term accumulation result, and accordingly, the time required for the presence estimation and the time required for the absence estimation are variably set.

  Further, the rotational speed control of the fan 8 and the wind direction control of the upper and lower blades 12 and the left and right blades are performed according to the air conditioning setting in each of the areas A to I. These controls will be described below.

  Wind direction control during heating is performed by controlling the wind direction in front of the person's feet in the area where it is determined that there is a person, so that warm air reaches the vicinity of the feet, and during air conditioning, the wind direction control is performed above the person's head. By controlling, the cool air reaches above the head. The wind direction is adjusted by the rotational speed of the fan 8 and the angles of the upper and lower blades 12 or the left and right blades.

  FIG. 18 shows the rotation control of the upper and lower blades 12, and when the operation of the air conditioner is stopped, the front panel 4, the upper and lower blades 12, and the middle blade 14 are all closed as shown in FIG. 18 (a). It is in.

  During cooling, the front panel 4, the upper and lower blades 12 and the middle blade 14 are moved from the state shown in FIG. 18 (a) in order to allow the blown air (cold air) to reach above the human head (cooling ceiling airflow). The state shown in FIG. 18C is reached through the state shown in b). First, the arms 18 and 20 are driven and controlled so that the front panel 4 is separated from the front opening 2 a, and the arms 22 and 24 are driven and controlled so that the upper and lower blades 12 are separated from the outlet 10.

  In the state of FIG. 18C, the air blown out from the blowout port 10 is guided in the horizontal direction by the upper and lower blades 12, but the downstream end of the upper and lower blades 12 is curved upward, so that it is far from the room. Can send air up to. At this time, the upper part of the blower outlet 10, that is, the lower part of the front panel 4 is closed by the middle blade 14, and a part of the air blown out from the blower outlet 10 is not led to the front opening 2 a.

On the other hand, at the time of heating, in order to make the blown air (warm air) reach the vicinity of the person's feet (heating airflow), the state shown in FIG. 18 (a) to the state shown in FIG. 18 (b) are passed through FIG. The state shown in (d) is reached. In the state of FIG. 18 (d), the air blown out from the outlet 10 is
Although being guided obliquely downward by the upper and lower blades 12, since the downstream end of the upper and lower blades 12 is curved toward the main body, warm air that tends to accumulate above the room can be sent to the lower part of the room.

  In addition, FIG.18 (e) is utilized at the time of air conditioning before stabilization, and blowing air is directed to a human body (air flow for human bodies).

  FIG. 19 shows the set number of rotations of the fan 8 when air conditioning is performed in each of the areas A to I. A1, A2, and A3 are reference rotations of areas at short distance, medium distance, and long distance from the indoor unit, respectively. A4 is a rotation speed difference due to a difference in region when the distance is the same, and is set as follows, for example.

A1: 800 rpm (during heating), 700 rpm (during cooling)
A2: 1000 rpm (during heating), 900 rpm (during cooling)
A3: 1200rpm (during heating), 1100rpm (during cooling)
A4: 100rpm (common for cooling and heating)
Here, the expression “relative position” is introduced as an expression representing the positional relationship with the indoor unit, such as the distance from the indoor unit in each region, the angle from the front of the indoor unit, and the height difference.

  Further, the degree of air conditioning that is easy to air-condition in each region is expressed by an expression of air conditioning requirement level. It is assumed that the higher the air conditioning requirement level, the more difficult the air conditioning is, and the lower the air conditioning requirement level, the easier the air conditioning. For example, as the distance from the indoor unit increases, the blown air is difficult to reach and the air conditioning is difficult to perform. That is, the air conditioning requirement level and the relative position from the indoor unit are closely related, and in this embodiment, the air conditioning requirement level is determined according to the relative position from the indoor unit.

  Therefore, it means that the set rotation speed of the fan 8 in the case of performing air conditioning in each of the areas A to I is set higher as the air conditioning requirement level is higher. That is, as the position of the area to be air-conditioned is farther from the indoor unit, the set rotational speed of the fan 8 is set higher, and when the distance from the indoor unit is the same, the fan 8 is shifted to the left and right from the front of the indoor unit. The set rotation speed is set high. In addition, when there is one area to be air-conditioned, it is set to the set rotation speed (air volume) of that area.

  FIG. 20 shows the set angles of the upper and lower blades 12 and the left and right blades during heating. B1, B2, and B3 are the reference upper and lower blade angles of the regions at short distance, medium distance, and long distance from the indoor unit, respectively. , B4 is the angle difference between the upper and lower blades when the distance is the same, whereas C1 and C2 are the reference left and right blade angles of the left and right regions (the counterclockwise direction is the counterclockwise direction), and C3 and C4 are the differences in the regions The angle difference between the left and right blades is, for example, set as follows. The angle of the upper and lower blades 12 is an angle when measured in the counterclockwise direction with reference to this position as 0 ° when the line connecting the front and rear ends of the blade is horizontal with the blades convex upward. That is.

B1: 70 °
B2: 55 °
B3: 45 °
B4: 10 °
C1: 0 °
C2: 15 °
C3: 30 °
C4: 45 °
That is, when heating the area A or B close to the indoor unit, the upper and lower blades 12 are set to a first angle (for example, 70 °), and the rotation speed of the fan 8 is set to the first rotation speed (for example, 70 °). , 800 rpm), and the wind direction is controlled at the edge of the indoor unit side (in front of the person's feet) in the region A or B so that the warm air reaches the vicinity of the feet. In addition, when heating the area C, D, E or F at a medium distance from the indoor unit, the upper and lower blades 12 are set to a second angle (for example, 55 °) smaller than the first angle, The rotation speed of the fan 8 is set to a second rotation speed (for example, 1000 rpm) higher than the first rotation speed, and the wind direction is directed to the edge on the indoor unit side (in front of the human foot) in the region C, D, E, or F. The warm air is made to reach the vicinity of the feet. Furthermore, when heating the area G, H, or I farthest from the indoor unit, the upper and lower blades 12 are set to a third angle (for example, 45 °) smaller than the second angle, and the rotation of the fan 8 is performed. The number is set to a third rotational speed (for example, 1200 rpm) higher than the second rotational speed, and the wind direction is controlled at the edge of the indoor unit side (in front of the human foot) in the region G, H, or I, and in the vicinity of the foot The warm air is made to reach.

  FIG. 21 shows the set angles of the upper and lower blades 12 and the left and right blades during cooling in the rising or unstable region, and E1, E2, and E3 are reference points for regions at short distance, medium distance, and long distance from the indoor unit, respectively. The upper and lower blade angles, E4, is the angle difference between the upper and lower blades due to the difference in the area when the distance is the same, while F1 and F2 are the reference left and right blade angles in the left and right regions (counterclockwise is the positive direction), and F3 and F4 Is the angle difference between the left and right blades due to the difference in area, and is set as follows, for example. Note that “rise” refers to the time when the operation of the air conditioner is started, and “unstable region” refers to a state where the current indoor air-conditioning state does not satisfy a set condition (for example, a set temperature).

E1: 50 °
E2: 35 °
E3: 25 °
E4: 10 °
F1: 0 °
F2: 15 °
F3: 25 °
F4: 35 °
FIG. 22 shows the setting angles of the upper and lower blades 12 and the left and right blades during cooling in the stable region, where H1 is a reference upper and lower blade angle in the case of ceiling airflow, and H2 is a reference upper and lower angle in the case of stripping airflow. The blade angle, H3 is the upper limit blade angle difference due to the difference in distance, whereas I1 and I2 are the reference left and right blade angles in the left and right regions (counterclockwise is the positive direction), and I3 and I4 are the left and right blades due to the difference in regions The angle difference is set as follows, for example. The stable region is a state where the current indoor air conditioning state is a set condition (for example, a set temperature).

H1: 180 °
H2: 190 °
H3: 5 °
I1: 0 °
I2: 15 °
I3: 25 °
I4: 35 °
Here, as shown in FIG. 18 (c), the ceiling airflow is the airflow when the upper and lower blades 12 are positioned at the lower part of the air outlet 10 and all the blown air is received by the concave surface of the blade and the air is sent out. This means that the upper and lower blades 12 are located slightly above the position at the time of the ceiling air flow, and a part (a small amount) of the blown air is also flown to the convex side of the blade (below the blade). It is an air flow when the wind is sent out in a state where condensation does not easily occur on the convex surface.

When cooling the area A or B close to the indoor unit, the upper and lower blades 12 are set below a predetermined angle (for example, 5 °) from the horizontal, and the rotational speed of the fan 8 is the first rotational speed (when heating) First
The number of revolutions is set to 700 rpm, for example, so that the cool air reaches above the head of the area A or B, and the cool air falls like a shower. Further, when cooling the region C, D, E, or F at a medium distance from the indoor unit, the upper and lower blades 12 are set substantially horizontal, and the rotational speed of the fan 8 is a second higher than the first rotational speed. The rotation speed is set to be lower than the second rotation speed at the time of heating, for example, 900 rpm, and is set so that the cool air reaches above the area C, D, E, or F overhead. Further, when cooling the region G, H, or I farthest from the indoor unit, the upper and lower blades 12 are set upward by a predetermined angle (for example, 5 °) from the horizontal, and the rotation speed of the fan 8 is the second rotation. Is set to a third rotational speed higher than the number (for example, 1100 rpm, which is smaller than the third rotational speed during heating), and is set to allow the cold air to reach above the region G, H, or I overhead. Yes.

  Next, the wind direction control performed according to the number of areas to be air-conditioned will be described with reference to the flowchart of FIG.

  After the operation of the air conditioner is started, the presence / absence determination of a person in the areas A to I is first performed in step S41, and one area determined to have a person in step S42, that is, one area to be air-conditioned. In such a case, in step S43, air conditioning is performed based on the air volume and direction set according to the area. If it is determined in step S42 that there is not one area to be air-conditioned, it is determined in step S44 whether there are two areas to be air-conditioned. If there are two areas to be air-conditioned, the process proceeds to step S45.

  In step S45, the air volume is set to the set air volume of the area where the air conditioning requirement is high, and the arrangement mode of the two areas is identified as one of the five modes as shown in FIG. 24, and in the next step S46, Control is performed as shown in Table 6 according to the identified mode.

  Here, mode 1 represents the case of two areas adjacent to each other with a medium distance and the front of the indoor unit, and mode 2 represents the case of two areas adjacent to each other in the front-rear relationship with the angle substantially equal to the indoor unit. Represents. In addition, mode 3 represents the case of two regions where the angle with the indoor unit is substantially the same and is separated in the longitudinal relationship, mode 4 represents the case of two regions where the distance to the indoor unit is substantially the same and the angle is different, Mode 5 represents the case of two regions that are separated, in other words, two regions that are different in distance and angle from the indoor unit.

The up-and-down wind directions of modes 1 to 4 are fixed to a low demand area during heating, and are fixed to a high demand area during cooling. In addition, the vertical wind direction in mode 5 controls the operation of the upper and lower blades 12 and after stopping for a predetermined time (fixed angle) in the first region of the two regions (first and second regions), The operation of changing the wind direction toward the first region is repeated after changing the wind direction toward the second region and stopping in the second region for a predetermined time. In addition, the stop time of each area | region is each set, for example according to the distance from an indoor unit, and it is preferable to lengthen a stop time, so that the distance from an indoor unit is far.

  The left and right wind directions in mode 1 are fixed at the center of two adjacent areas. In modes 2 and 3, it is assumed that the two areas are in substantially the same direction with different distances when viewed from the indoor unit. The wind direction is fixed in a highly requested area. Further, the left and right wind directions of mode 4 and the mode 5 comprising the arrangement of two spaced apart areas are controlled in the same way as the control of the upper and lower blades 12, and after stopping for a predetermined time in the first area, The operation of changing the wind direction toward the first area is repeated after changing the wind direction toward the second area and stopping in the second area for a predetermined time. The stopping time of each area is set according to the relative position from the indoor unit to each area, for example, the angle from the front of the indoor unit, and it is preferable to increase the stopping time as the angle from the front of the indoor unit increases. .

  If it is determined in step S44 that there are not two areas to be air-conditioned, in step S47, three or more areas to be air-conditioned are selected from the two modes, the normal mode and the special mode, depending on the arrangement. Judgment. Here, the special mode represents the case of a total of three areas, that is, a medium distance and two areas adjacent to each other across the front of the indoor unit, and one area that is a long distance and located in front of the indoor unit. The case of three or more areas excluding is denoted as normal mode. When there are three or more areas to be air-conditioned, the air volume is set to the set air volume of the area with the highest air-conditioning requirement level, and when it is determined to be the special mode (center adjacent) shown in FIG. In step S48, the wind direction is set in the same manner as in mode 1 of FIG.

  On the other hand, if it is determined in step S47 that the mode is not the special mode, control in the normal mode shown in FIG. 25 (b) or (c) is performed in step S49, and the vertical wind direction is the region closest to the indoor unit. The angle of the upper and lower blades 12 is changed between the set angle of the upper and lower blades 12 and the set angle of the upper and lower blades 12 in the region farthest from the indoor unit.

  In the normal mode, the left and right wind directions are set to the left end angle and the right end angle at the left and right blade setting angles in the regions at both ends (regions C and I in FIG. 25B and regions C and H in FIG. 25C). Set and stop at the left end angle for a predetermined time, then change the wind direction toward the right end side (swing), stop at the right end angle for a predetermined time and then change the wind direction toward the left end side region (swing) repeat. Note that the operating speed of the left and right blades during the swing is set slower than the operating speed of the left and right blades in the modes 4 and 5 described above. In addition, the stop time at the left end angle or the right end angle is set in accordance with, for example, the angle from the front of the indoor unit, and it is preferable that the stop time is increased as the angle from the front of the indoor unit increases.

  In addition, after each air-conditioning control is performed in step S43, S46, S48 or S49, it returns to step S41.

  When the indoor unit is arranged as shown in FIG. 14, it is determined that the indoor unit is installed in the vicinity of the left side wall using the first to fifth sensors 26, 28, 30, 32, and 34. It is also possible to control the operation of the left and right blades only in the region located on the right side of the left side wall. In this case, the human body detection device including the first to fifth sensors 26, 28, 30, 32, and 34 functions as an automatic installation position recognition unit for the indoor unit.

  It should be noted that at least two sensors may be provided as means for automatically recognizing the installation position of the indoor unit. In the example shown in FIG. 4, the first and second sensors 26 and 28 whose optical axes are on the same plane are provided. To take further explanation.

  When two sensors 26 and 28 are provided, outputs for each cycle T1 from the two sensors 26 and 28 are accumulated for a predetermined time (for example, 3 to 4 hours), and the accumulated reaction result is compared with one threshold value. Thus, the two areas are divided into a living area and a non-living area or two living areas. Note that the threshold value to be compared may be, for example, the second threshold value described above.

  In the embodiment, the five human body detection sensors are provided. However, the present invention is not limited to this, and may be one, for example.

  It is to be noted that, by appropriately combining any of the various embodiments, the effects possessed by them can be produced.

  As described above, the air conditioner according to the present invention can easily bind the lead wire connecting the electrical component directly mounted on the movable panel and the electrical component connection part of the indoor unit body, and can be electrically connected. Since reliability can be ensured, it can be applied to all other devices having a configuration in which an electrical component is mounted on a movable part, and in particular, can be applied to an air conditioner, an air cleaner, or the like having a sensor unit.
