Hereinafter, embodiments of an air conditioner according to the present disclosure will be described with reference to the drawings.

(embodiment)
An air conditioner according to an embodiment can be configured as shown in FIG. FIG. 1 is a block diagram showing a schematic configuration of an air conditioner.

The air conditioner 1 has an operation terminal 94 a , an indoor unit 10 and an outdoor unit 100 . The indoor unit 10 is arranged inside the indoor RM, and the outdoor unit 100 is arranged outdoors. The operation terminal 94a receives an operation instruction from the living body CR existing in the indoor RM, and transmits an instruction to the indoor unit 10 according to the received operation instruction. A living body CR is, for example, a person. The operating terminal 94a is, for example, a remote controller.

The indoor unit 10 has a radar 2 , a control section 3 , a wind deflector 4 and a wind deflector 5 . The control unit 3 performs air conditioning processing and control using the radar 2 according to the command received from the operation terminal 94a. The control unit 3 has a radar control mode (first control mode) and a normal control mode (second control mode) as control modes. The radar control mode is a mode for performing control using the radar 2 . The normal control mode is a mode for performing normal control without using the radar 2 .

In the radar control mode, the radar 2 continuously detects the position of the living body CR in the indoor RM under the control of the controller 3 . While tracking the detected position of the living body CR, the control unit 3 performs a first movement in a direction toward the detected position of the living body CR and a second movement in a direction away from the detected position of the living body CR. The wind direction plates 4 and 5 are controlled so as to perform either operation.

As a result, when the living body CR existing in the indoor RM moves in the indoor RM, the way in which the conditioned air is blown out from the indoor unit 10 can be dynamically changed according to the movement of the living body CR. The comfort of living body CR can be improved dynamically.

Specifically, the indoor unit 10 performs air conditioning processing on the air sucked from the room RM through the suction port, and blows the conditioned air subjected to the air conditioning processing toward the room RM. Air conditioning includes, for example, absorption heat treatment, heat treatment, dehumidification treatment, humidification treatment, air blowing treatment, and air cleaning treatment. Absorption heat treatment, heat treatment, dehumidification treatment, humidification treatment, air blowing treatment, and air cleaning treatment are performed in cooling operation mode, heating operation mode, dehumidification operation mode, and humidification operation modes (main operation modes) of the air conditioner 1, respectively. It corresponds to the operation mode, the fan operation mode, and the air cleaning operation mode.

The main operation mode can be arbitrarily combined with the control modes (radar control mode, normal control mode). The air conditioner 1 can take any of a cooling operation mode, a heating operation mode, a dehumidification operation mode, a humidification operation mode, a ventilation operation mode, and an air cleaning operation mode in the radar control mode. The same applies to the normal control mode.

In the air conditioning process, the humidification process may be omitted. At this time, the humidification operation mode may be omitted as the operation mode of the air conditioner 1 .

The air conditioner 1 has, as auxiliary operation modes, no wind mode ON (first mode) and no wind mode OFF (second mode). The auxiliary operation mode can be arbitrarily combined with the control modes (radar control mode, normal control mode), and can be arbitrarily combined with the main operation mode. When conditioned air is blown out from the indoor unit 10, when the conditioned air is blown out from the indoor unit 10, two types of wind speeds are mixed to generate a turbulent flow that spreads over a wide area, generating a natural wind (so-called wind with a feeling of calmness). .

The air conditioner 1 may have an automatic operation mode as an operation mode. The air conditioner 1 detects the temperature of the room RM with a temperature sensor (not shown). In the automatic operation mode, the air conditioner 1 operates in the heating operation mode if the detected temperature is higher than the set temperature, and operates in the heating operation mode if the detected temperature is lower than the set temperature.

Various methods can be applied to the air cleaning process, and an electric dust collection method may be applied, or a fan method may be applied. In the electrostatic precipitator, dust-charged air is passed through a filter, and the dust is absorbed by the oppositely charged filter, thereby removing dust from the air. In the fan system, air is passed through a fine-mesh filter such as a HEPA filter, and dust is filtered out by the filter, thereby removing dust from the air. Alternatively, the air cleaning process may employ a method of releasing ions into the air, or a method of irradiating the inside of the housing of the air conditioner 1 with ultraviolet rays (UV) to sterilize the air. .

In the air conditioner 1 , the indoor unit 10 has a fan 23 , a heat exchanger 22 , a ventilation member 6 and a receiver 94 in addition to the radar 2 , the controller 3 , the wind direction plates 4 and 5 . The control unit 3 includes a control device 80 , a drive circuit 81 , a drive circuit 82 , a drive circuit 83 , a fan motor 84 , a fan motor 85 , a fan motor 86 and a switching motor 87 . The outdoor unit 100 has a fan 123 , a heat exchanger 122 , a four-way valve 124 , a compressor 125 and a controller 103 . The control unit 103 includes a control device 180 , a drive circuit 181 , a drive circuit 182 , a drive circuit 183 , a fan motor 184 , a switching motor 185 and a motor 186 .

In the indoor unit 10 , the fan 23 is arranged near the heat exchanger 22 . The fan 23 guides the air sucked from the indoor RM through the inlet of the indoor unit 10 to the heat exchanger 22 and guides the conditioned air heat-exchanged in the heat exchanger 22 to the outlet of the indoor unit 10 . The control unit 3 drives the fan motor 84 with the drive circuit 81 to rotate the fan 23 around the rotation axis. The controller 3 can change the rotation speed of the fan 23 .

Heat exchanger 22 may take a variety of configurations. For example, heat exchanger 22 includes a plurality of fins and a refrigerant circuit (not shown) connected thereto. The plurality of fins are in thermal contact with the refrigerant circuit, with the refrigerant circuit running near them. The heat exchanger 22 heat-exchanges air sucked from the indoor RM with the refrigerant.

In the outdoor unit 100 , the fan 123 is arranged near the heat exchanger 122 . Fan 123 rotates under the control of control unit 103 . As a result, the fan 123 draws in outside air and guides it to the heat exchanger 122 , and discharges the outside air heat-exchanged by the heat exchanger 122 to the outside of the outdoor unit 100 . The control unit 103 drives the fan motor 184 with the drive circuit 181 to rotate the fan 123 around the rotation axis. The controller 3 can change the rotation speed of the fan 123 via the controller 103 .

Heat exchanger 122 may take on a variety of configurations. For example, heat exchanger 122 includes a plurality of fins and a refrigerant circuit connected thereto. The plurality of fins are in thermal contact with the refrigerant circuit, with the refrigerant circuit running near them. The heat exchanger 122 exchanges heat with the refrigerant against the outside air.

A four-way valve 124 is arranged in the refrigerant circuit. The four-way valve 124 can switch the flow path of the refrigerant in the refrigerant circuit between the cooling side and the heating side according to control by the control unit 103 . The control unit 103 can drive a switching motor 185 with a drive circuit 182 to switch the four-way valve 124 between the cooling side and the heating side. The controller 3 can switch the four-way valve 124 between the cooling side and the heating side via the controller 103 .

Compressor 125 is arranged in the refrigerant circuit. The compressor 125 compresses the refrigerant and sends it out into the refrigerant circuit under the control of the controller 3 . The control unit 103 drives the motor 186 with the drive circuit 183 to cause the compressor 125 to perform the cycle operation of compressing the refrigerant. The control unit 3 can change the number of cycles of the compressor 125 (the number of compression cycles performed per unit time) via the control unit 103 .

For example, the air conditioner 1 switches the four-way valve 124 to the cooling side in the cooling operation mode by the control unit 3 and the control unit 103 . The heat exchanger 22 performs heat absorption, causes the refrigerant to absorb heat from the air in the room RM, and blows out the heat-absorbed conditioned air to the room RM. The heat exchanger 122 performs heat radiation processing to release the heat absorbed by the refrigerant to the outside air.

Alternatively, the air conditioner 1 switches the four-way valve 124 to the heating side in the heating operation mode by the control unit 3 and the control unit 103 . The heat exchanger 122 performs endothermic heat treatment, causing the refrigerant to absorb heat from the outside air. Heating is performed in the heat exchanger 22, the heat absorbed by the refrigerant heats the air in the room RM, and the heated conditioned air is blown out to the room RM.

The wind direction plates 4 and 5 respectively adjust the wind direction of the conditioned air blown into the room RM. Wind direction means the direction of the wind. In this specification, the control unit 3 directly controls the direction in which the wind direction plates 4 and 5 face, but the direction in which the direction plates 4 and 5 face and the direction of the wind immediately after being blown out from the outlet of the indoor unit 10 ( wind direction) are treated as roughly the same. That is, the wind direction plates 4 and 5 can adjust the wind direction by their orientation, and the controller 3 can control the wind direction by controlling the direction of the wind direction plates 4 and 5 . It should be noted that the directions of the wind direction plates 4 and 5 can be individually controlled. As a result, it is possible to blow out air whose air direction is aligned in one direction from the entire air outlet of the indoor unit 10, and two or more of the air outlets of the indoor unit 10 divided by the plurality of wind direction plates 4, 5, etc. It is also possible to blow two or more winds with different wind directions from the region.

The wind direction plate 4 can be switched between a closed position and an open position. The wind direction plate 4 closes the outlet when switched to the closed position. The wind direction plate 4 opens the blowout port in a state of being switched to the open position. The wind direction plates 4 and 5 adjust the wind direction of the conditioned air blown into the room RM in a state in which the air outlet is open. The wind direction plate 4 adjusts the wind direction of the conditioned air in the vertical direction. The wind direction plate 5 adjusts the wind direction of the conditioned air in the horizontal direction.

For example, the wind deflectors 4, 5 may be configured as shown in FIGS. 2-4. FIG. 2 is a cross-sectional view showing the configuration of the indoor unit 10, showing a state in which the wind direction plate 4 is in the closed position. FIG. 3 is a cross-sectional view showing the configuration and operation of the indoor unit 10, showing a state in which the wind direction plate 4 is in the open position. FIG. 4 is a perspective view showing the configuration and operation of the indoor unit 10, showing a state in which the wind direction plate 4 is in the open position. Hereinafter, the longitudinal direction of the indoor unit 10 is defined as the X direction, the height direction of the indoor unit 10 is defined as the Z direction, and the direction perpendicular to the X and Z directions is defined as the Y direction.

As shown in FIGS. 2 to 4, the indoor unit 10 further has a housing 21 and a filter 24 in addition to the configuration shown in FIG.

The housing 21 is formed in a substantially rectangular parallelepiped shape extending in the X direction. Note that the housing 21 may be formed in other shapes. The housing 21 is hung, for example, on the wall of the room RM. The housing 21 has an upper surface 21a and a lower surface 21b. The upper surface 21a is provided at or near the upper end of the housing 21 and faces substantially upward. The lower surface 21b is provided at or near the lower end of the housing 21 and faces substantially downward.

A ventilation path 31 , a suction port 32 , and a blowout port 33 are provided in the housing 21 . The ventilation path 31 is provided inside the housing 21 . The suction port 32 opens to the upper surface 21a of the housing 21, for example. The blowout port 33 opens to the lower surface 21b of the housing 21, for example. The suction port 32 and the blowout port 33 may open to other parts of the housing 21 .

The indoor unit 10 allows air to pass through the ventilation path 31 . Wind is the flow of gas, such as air. The suction port 32 is provided at one end of the ventilation passage 31 and communicates the ventilation passage 31 with the outside of the indoor unit 10 . The blowout port 33 is provided at the other end of the ventilation passage 31 and communicates the ventilation passage 31 with the outside of the indoor unit 10 . In other words, the ventilation path 31 is provided between the suction port 32 and the blowout port 33 inside the housing 21 .

The heat exchanger 22 is provided in the ventilation passage 31 . The heat exchanger 22 exchanges heat with the surrounding gas in the ventilation passage 31 . Thereby, the heat exchanger 22 cools the air flowing through the air passage 31 during the cooling operation, and heats the air flowing through the air passage 31 during the heating operation.

Fan 23 is provided in ventilation path 31 . The fan 23 rotates around the rotation axis Axf extending in the X direction, thereby blowing air from the suction port 32 to the blowout port 33 in the ventilation passage 31 . As a result, the indoor unit 10 sucks indoor air from the suction port 32 into the air passage 31 and blows out the air (wind) in the air passage 31 from the air outlet 33 . Therefore, in this specification, the side of the ventilation passage 31 near the suction port 32 is called upstream, and the side near the blowout port 33 is called downstream.

Fan 23 is positioned downstream of heat exchanger 22 . Therefore, when the fan 23 generates wind, the air sucked from the suction port 32 passes through the fins of the heat exchanger 22 . Thereby, the air flowing through the ventilation path 31 exchanges heat with the heat exchanger 22 .

The filter 24 is provided at the suction port 32 or in the vicinity of the suction port 32 in the ventilation passage 31 . Filter 24 is located upstream of heat exchanger 22 . The filter 24 covers the suction port 32 from inside the housing 21 . The filter 24, for example, filters the air sucked from the suction port 32 and captures dust in the air.

The air deflector 4 may include a plurality of air deflectors 25A and 25B. The plurality of wind direction plates 25A and 25B are members for adjusting the wind direction of conditioned air in the vertical direction, and are also called vertical louvers. The wind direction plate 25A forms the flow path C1 for the conditioned air, and the wind direction plate 25B forms the flow path C2 for the conditioned air. Each of the wind direction plates 25A and 25B has a shaft portion 41 and a plate portion 42 .

The shaft portion 41 is formed in a substantially columnar shape extending in the X direction. The shaft portion 41 is rotatably supported by the housing 21 around a rotation axis Axl extending in the X direction. In addition, each of the plurality of wind direction plates 25A and 25B has an individual rotation axis Axl. The plate portion 42 protrudes from the shaft portion 41 in a direction substantially orthogonal to the rotation axis Axl. The plate portion 42 is formed in a substantially rectangular plate shape extending in the X direction.

The wind deflector 25A is supported by the rotary shaft Axl, and the wind deflector motor 85 is controlled by the drive circuit 82 to be movable between the closed position Pc1 and the open position Po1. The wind deflector 25B is supported by the rotating shaft Axl, and the wind deflector motor 85 is controlled by the drive circuit 82 to be movable between the closed position Pc2 and the open position Po2.

As shown in FIG. 2, the wind direction plate 25A closes the ventilation opening C1, which is the outlet of the flow path C1, in a state of being switched to the closed position Pc1. The wind direction plate 25B closes the ventilation port C2, which is the outlet of the second flow path, in a state of being switched to the closed position Pc1. The air vent C1 and the air vent C2 form the air outlet 33 of the indoor unit 10 .

As shown in FIGS. 3 and 4, the wind direction plate 25A opens the ventilation port C1 in a state of being switched to the open position Po1. The wind direction plate 25B opens the ventilation port C2 in a state of being switched to the open position Po1.

The open position Po1 includes various positions where the wind direction plates 25A and 25B partially open the outlet 33 . For example, the open position Po1 includes a position where the airflow direction plates 25A and 25B face substantially horizontally, a position where the airflow direction plates 25A and 25B face downward, and a plurality of positions between these two positions, as shown in FIG. include. That is, the wind direction plates 25A and 25B are rotatable between a position facing substantially horizontally and a position facing downward.

The airflow direction plates 25A and 25B positioned at the open position Po1 adjust the vertical direction (+Z direction and -Z direction) of the air discharged from the blowing port 33 according to the direction of the airflow direction plates 25A and 25B. That is, the wind direction plates 25A and 25B are oriented substantially horizontally as shown in FIG. 3, so that the indoor unit 10 emits wind substantially horizontally. On the other hand, the wind direction plates 25A and 25B face downward, so that the indoor unit 10 emits wind downward.

The wind deflector 5 is supported by a rotating shaft Ax2 (not shown), and a wind deflector motor 86 is controlled by a drive circuit 82 to be movable between an open position on the -X side and an open position on the +X side. be.

The air deflector 5 may include a plurality of air deflectors 29-1 to 29-k and 29-(k+1) to 29-2k. A plurality of wind direction plates 29-1 to 29-k and 29-(k+1) to 29-2k are members for adjusting the wind direction of conditioned air in the horizontal direction (-X direction and +X direction), and both the left and right louvers are Called. The directions of the -X side air deflectors 29-1 to 29-k and the +X side air deflectors 29-(k+1) to 29-2k may be independently controlled by the control unit 3.

The wind direction plates 29-1 to 29-k on the -X side are connected to a common rotation axis Ax2, and the wind direction plate motor 86 is controlled by the drive circuit 82 to open the -X side end and the +X side end open positions. It may be possible to collectively move between. The wind direction plates 29-(k+1) to 29-2k on the +X side are connected to a common rotation axis Ax2. It may be movable collectively between the positions.

The ventilation member 6 shown in FIG. 1 can be switched between a closed position and an open position. The ventilation member 6 is inserted into a part of the flow path of the conditioned air blown into the room RM in a state of being switched to the closed position, and changes the opening ratio of the part of the flow path. While the ventilation member 6 is switched to the open position, the insertion into the part of the channel is released (for example, the ventilation member 6 is retracted from the part of the channel), and the opening ratio of the part of the channel is determined. returned.

In the air conditioner 1, the control unit 3 switches the ventilation member 6 to the closed position when the calm mode as the auxiliary operation mode is turned on. The ventilation member 6 is selectively inserted into the first flow path to change the opening ratio of the first flow path in a state of being switched to the closed position. The open area ratio of the second channel is maintained as it was. The controller 3 switches the ventilation member 6 to the open position when the calm mode ON as the auxiliary operation mode is canceled (when the calm mode is turned OFF). The ventilation member 6 is retracted from the first channel while being switched to the open position, and the opening ratio of the first channel is restored.

For example, the ventilation member 6 can be configured as shown in FIGS. 3-6. FIG. 3 is a cross-sectional view showing the configuration and operation of the indoor unit 10, showing a state where the ventilation member 6 is in the open position. FIG. 4 is a perspective view showing the configuration and operation of the indoor unit 10, showing a state where the ventilation member 6 is in the open position. FIG. 5 is a cross-sectional view showing the configuration and operation of the indoor unit 10, showing a state where the ventilation member 6 is in the closed position. FIG. 6 is a perspective view showing the configuration of the ventilation member 6. As shown in FIG.

As shown in FIGS. 3 and 4, the ventilation member 6 is accommodated in the recess 21c of the housing 21 provided in the vicinity of the outlet 33 while being switched to the open position Po2. The depression 21 c is recessed from the inner surface 21 d of the housing 21 forming part of the ventilation passage 31 . The ventilation member 6 positioned at the open position Po2 is accommodated in the depression 21c, and is thus restrained from obstructing the wind flowing through the ventilation passage C1.

As shown in FIG. 5, the ventilation member 6 is selectively inserted into the flow path C1 in a state where it is switched to the closed position Pc2 to change the opening ratio of the flow path C1. The opening ratio of the flow path C1 becomes smaller than before the ventilation member 6 is inserted. The ventilation member 6 includes a ventilation member 26A in which a plurality of ventilation holes 56 are arranged, as shown in FIG. The ventilation member 26A is supported by the shaft portion 51 and is movable between the closed position Pc2 and the open position Po2 by controlling the switching motor 87 by the drive circuit 83. As shown in FIG. Then, when moving to the closed position Pc2, as shown in FIG. 7, the wind moving in the ventilation passage 31 by the fan 23 passes through the ventilation port 56 and changes to the wind W2a.

On the other hand, the blowout port 33 forming the flow path C2 is not provided with a ventilation member. The opening ratio of the channel C2 is maintained as it was. That is, the wind discharged from the flow path C2 becomes the wind W1a (laminar flow) that does not pass through the ventilation member. As a result, the wind W2a passing through the ventilation member 26A provided in the flow path C1 and the wind W1a passing through the flow path C2 not provided with the ventilation member are formed adjacent to each other.

In this case, the flow velocity of the wind W2a is high in accordance with the decrease in the aperture ratio of the flow path C1. Therefore, the wind W2a draws in the wind W1a. As a result, the wind W1a hits the wind W2a. In addition, the wind W2a that has transitioned to turbulent flow is diffused and hits the wind W1a that flows adjacent to the wind W2a. Thus, the wind W1a and the wind W2a having different flow velocities and states (laminar flow or turbulent flow) hit each other by flowing side by side. That is, the wind W1a that does not pass through the ventilation member and the wind W2a that has passed through the ventilation member 26A (ventilation port 56) interfere with each other.

When the wind W1a and the wind W2a hit each other, for example, clumps of the wind W1a and the wind W2a are broken, and the turbulent wind W2a is carried by the wind W1a. The wind W1a and the wind W2a cause such various interactions to generate a turbulent flow Ws that spreads over a wide area. As a result, the turbulent flow Ws emitted from the indoor unit 10 becomes closer to the natural wind (so-called calm wind) than the wind immediately after being discharged from the outlet 33 .

The radar 2 shown in FIG. 1 can detect the position and speed of the living body CR in the indoor RM. The radar 2 is a Doppler radar such as millimeter wave radar and microwave radar. The radar 2 has a transmitter 2a, a receiver 2b, and a signal processor 2c. The radar 2 generates radio waves such as millimeter waves and microwaves in the signal processing section 2c, transmits them from the transmission section 2a to the living body CR, receives the reflected waves in the reception section 2b, and transfers them to the signal processing section 2c. Although the radar 2 is provided at any position in the indoor unit 10, it is desirable to be provided at a position where the position and speed of the living body CR in the room RM can be easily detected. The radar 2 may be embedded in the +Y side portion of the housing 21 near the center in the X direction, as indicated by the dashed lines in FIGS.

The radar 2 can detect the position of the living body CR as shown in FIG. FIG. 8 is a diagram showing the operation of radar. In FIG. 8, the detected positions of the living body CR are indicated by dots.

The radar 2 detects the target space and the position of the living body CR within the target space under the control of the control unit 3 . The radar 2 continuously transmits and receives radio waves to and from the living body CR, continuously detects the position of the living body CR, and continuously supplies detection results to the control unit 3 .

For example, radar 2 detects an indoor RM having length L1, width W1, and area L1×W1. As shown in FIG. 9(a), the control unit 3 identifies the indoor RM having a length L1, a width W1, and an area L1×W1 as the target space according to the detection result of the radar 2, and assigns the space identifier SP1. assign. FIG. 9 is a diagram showing information detected by the radar 2, FIG. 9(a) shows information about space detected by the radar 2, and FIG. Indicates information about the CR.

The control unit 3 sets coordinates within the target space SP1. The radar 2 may detect the target space by further including the height of the space. In this case, the volume of the target space can also be detected. In FIG. 8, the identified object space is indicated by a rectangle and the horizontal and vertical coordinates are indicated. The radar 2 detects the position of the living body CR within the target space SP1 under the control of the control unit 3 .

The control unit 3 specifies the distance D1, the horizontal angle θ1, and the vertical angle α1 of the living body CR of ID1 according to the detection result of the radar 2, and specifies the distance D2, the horizontal angle θ2, and the vertical angle α2 of the living body CR of ID2. do.

The control unit 3 converts the distance, horizontal angle, and vertical angle of the two living bodies CR into coordinates (horizontal coordinate and vertical coordinate) in the object space. The control unit 3 recognizes that two living bodies CR exist at the coordinates, as indicated by dots in FIG. For each of the two living bodies CR, the control unit 3 determines that coordinates spatially close to temporally continuous detection results correspond to the same identifier, even if the living body CR has moved.

When one living body CR is detected by the radar 2, the control unit 3 locks onto the detected living body CR. When a plurality of living body CRs are detected by the radar 2, the control unit 3 selects one living body CR from among the plurality of living body CRs according to a predetermined condition, and locks onto the selected living body CR. The control unit 3 can continuously recognize the position of the locked-on living body CR according to the continuous detection results of the radar 2 . Thereby, the control unit 3 can track the locked-on living body CR.

Also, the radar 2 can detect the positions of the living body CR at a plurality of locations. The control unit 3 may assign a biometric identifier to each group of a plurality of spatially adjacent detection positions according to the detection result of the radar 2 . In the case of FIG. 8, the control unit 3 specifies the positional relationship between the plurality of detection positions in the collection of the plurality of detection positions for each of the two living bodies CR. Thereby, the control unit 3 can grasp the posture (for example, the posture of sitting on the floor, the posture of sitting on a chair, the standing posture, the lying posture, the crouching posture, etc.) of each of the two living bodies CR.

Further, as shown in FIG. 8, the radar 2 can detect the speed of the living body CR by the Doppler effect from the frequency difference (or wavelength difference) between the transmission wave and the reception wave in the signal processing unit 2c.

In the case of FIG. 8, the radar 2 also detects the velocity for each of the two living CRs. The control unit 3 specifies the speed v1 of the living body CR of ID1 and the speed v2 of the living body CR of D1 according to the detection result of the radar 2, as shown in FIG. 9B. In FIG. 8, the speed of each living body CR specified by the control unit 3 is indicated by the length of the line.

As a result, the direction of the wind blown from the indoor unit 10 can be controlled so as not to hit the living body CR while the locked-on living body CR is being tracked.

As shown in FIGS. 14(d) and 15(d), the controller 3 of the indoor unit 10 uses the radar 2 to determine the position of the living body CR in the indoor RM, continuing from FIGS. 14(c) and 15(c). detect. As shown in FIG. 14(d), the radar 2 detects that the living body CR exists at a planar position P12d on the +X side and the +Y side in the room RM.

It should be noted that the avoidance direction in the wind avoidance control can be arbitrarily set in the control unit 3 . The wind avoidance control may be a control in which the direction of the wind avoids the position of the living body CR in the horizontal direction, or a control in which the direction of the wind avoids the position of the living body CR in the vertical direction. Alternatively, the control may be such that the wind direction avoids the position of the living body CR in the vertical and horizontal directions.

As described above, in the present embodiment, in the air conditioner 1, the radar 2 continuously detects the position of the living body CR in the room RM. In the radar control mode, the control unit 3 controls the wind deflectors 4 and 5 so as to perform either the first operation or the second operation while tracking the detected position of the living body CR. That is, even if the living body CR moves, the wind direction plates 4 and 5 are controlled according to the current position of the living body CR. In the first operation, the wind direction plates 4 and 5 are controlled so that the wind direction is directed toward the detected position of the living body CR. In the second operation, the wind direction plates 4 and 5 are controlled so that the wind direction avoids the position of the living body to be detected. As a result, when the living body CR existing in the indoor RM moves in the indoor RM, the way in which the conditioned air is blown out from the indoor unit 10 can be dynamically changed according to the movement of the living body CR. The comfort of living body CR can be improved dynamically.

In addition, although the case where the indoor unit 10 has one radar 2 is illustrated in the embodiment, the indoor unit 10 may have a plurality of radars. In this case, since the indoor unit 10 detects the position of the living body CR using a plurality of radars, the accuracy of position detection can be easily improved.

It should be noted that in the radar control mode, which of the first operation and the second operation the control unit 3 controls the wind direction plates 4 and 5 to perform may be designated by the operation terminal 94a. . The operation terminal 94a is provided with a button for selecting wind control or wind avoidance control, and when the operation terminal 94a detects that the button is pressed, a command for wind control or wind avoidance control is sent from the operation terminal 94a to the room. It may be sent to unit 10 . Alternatively, the operation terminal 94a is provided with a button operation method (for example, simultaneous pressing of a plurality of buttons) for selecting wind control or wind avoidance control, and the operation terminal 94a detects the execution of the button operation method. At this time, a command for wind control or wind avoidance control may be transmitted to the indoor unit 10 from the operation terminal 94a. The control unit 3 can determine which of the first operation and the second operation is to be performed in accordance with the command received from among the command for wind control and the command for shelter control. As a result, in the radar control mode, it is possible to control the wind direction specified by the living body CR while tracking the detected position of the living body CR, thereby dynamically improving the comfort of the living body CR existing in the indoor RM. can.

Alternatively, in the radar control mode, which of the first operation and the second operation the control unit 3 controls the wind direction plates 4 and 5 to perform depends on the moving speed and moving direction of the living body CR. may be determined by For example, the control unit 3 may turn on the wind blow control when the living body CR approaches the radar 2 at a predetermined speed or more according to the detection result of the radar 2, or the living body CR may turn on the radar 2 Wind avoidance control may be turned on when the vehicle moves away from the vehicle at a predetermined speed or more. As a result, in the radar control mode, while tracking the detected position of the living body CR, it is possible to control the wind direction in accordance with the movement of the living body CR. can improve significantly.

Alternatively, whether the control unit 3 controls the wind direction plates 4 and 5 to perform the first operation or the second operation in the radar control mode may be determined in advance for each operation mode. good.

In the radar control mode, when the operation terminal 94a detects pressing of the button for commanding the first operation mode, a command for the first operation mode is transmitted from the operation terminal 94a to the indoor unit 10. The receiving device 94 will supply the command to the control part 3, if the command of a 1st operation mode is received. The first operation mode is, for example, cooling operation, heating operation, and blowing operation. In the radar control mode, when the operation terminal 94a detects pressing of the button for commanding the second operation mode, a command for the second operation mode is transmitted from the operation terminal 94a to the indoor unit 10. The receiving device 94 will supply the command to the control part 3, if the command of a 2nd operation mode is received. The second operation mode is, for example, dehumidification operation, humidification operation, and air cleaning operation. In the radar control mode, the control unit 3 controls the wind direction vanes 4 and 5 to perform the first operation when the command for the first operation mode is received. In the radar control mode, the control unit 3 controls the wind direction vanes 4 and 5 to perform the second operation when the command for the second operation mode is received. As a result, in the radar control mode, it is possible to perform wind direction control according to the driving mode while tracking the detected position of the living body CR, so that the comfort of the living body CR existing in the indoor RM can be dynamically improved. .

Alternatively, in the radar control mode, the control unit 3 may change the position range tracked by the radar 2 according to the auxiliary operation mode. In the radar control mode, when the control unit 3 does not receive a command to turn on the calm feeling mode as the auxiliary operation mode, as in the embodiment, the indoor RM (first position range) is set as the target space SP1, and the target space Detect the position (and velocity) of the living body CR in SP1. As a result, the control unit 3 can perform controls such as wind control and wind avoidance control while locking onto and tracking the living body CR within the target space SP1.

On the other hand, when the operation terminal 94a detects that the no wind feeling button 947 has been pressed, a command for turning on the no wind feeling mode is transmitted from the operation terminal 94a to the indoor unit 10 . In the radar control mode, when receiving a command to turn on the calm feeling mode as the auxiliary operation mode, the control unit 3 identifies a space (second position range) close to the indoor unit 10 in the indoor RM as the target space. Considering that the wind blown from the indoor unit 10 does not reach far when the no-wind feeling mode is on, it is appropriate to set the space close to the indoor unit 10 as the target space. For example, the control unit 3 specifies a partial area on the -Y side of the room RM in FIG. 12(a) as the target space, and as shown in FIG. (<W1) and assign the identifier SP2 of the space with area L2×W2 (<L1×W1). Then, similarly to the embodiment, the control unit 3 continuously detects the position (and speed) of the living body CR within the target space SP2. As a result, the control unit 3 can perform controls such as wind exposure control and wind avoidance control while locking on and tracking the living body CR within the narrower target space SP2 considering that the no-wind sensation mode is ON. can.

Further, in the radar control mode, the control unit 3 may change the number of revolutions of the fan 23 according to the distance to the living body CR detected by the radar 2 . The control unit 3 may increase the rotation speed of the fan 23 according to the detection result of the radar 2 so that the farther the living body CR is, the stronger the wind becomes.

12B and 13B, the control unit 3 controls the XY distance from the radar 2 to the horizontal position P12b and the The distance to the living body CR is obtained according to the difference of the position P13b from the Z height. The control unit 3 rotates the fan 23 at a rotational speed corresponding to the obtained distance, and blows conditioned air at an air volume indicated by the length of the dashed-dotted arrow. The same applies to the cases shown in FIGS. 12(c) and 13(c) and the cases shown in FIGS. 12(d) and 13(d).
