Embodiment 1 FIG.
The configuration of the air conditioner according to the present embodiment, the operation of the air conditioner according to the present embodiment, and the effects of the present embodiment will be described in order.

*** Explanation of configuration ***
With reference to FIG. 1 to FIG. 7, the configuration of the indoor unit 100 included in the air conditioner according to the present embodiment will be described.

  1, 2, and 3 illustrate the appearance of the indoor unit 100. FIG. 4 shows the indoor unit 100 in a state in which the front panel 101 is removed and one filter 180 is shifted. FIG. 5 shows a longitudinal section of the indoor unit 100 when the indoor unit 100 is cut in the left-right direction. FIG. 6 shows a longitudinal section of the indoor unit 100 when the indoor unit 100 is cut in the front-rear direction. FIG. 7 shows a configuration relating to airflow control of the indoor unit 100.

  The indoor unit 100 includes an indoor unit main body 110, a fan 120, a vane 130, a sensor 140, and a control device 150.

  The indoor unit main body 110 is installed in a room. A front panel 101 is detachably attached to the front surface of the indoor unit main body 110.

  The fan 120 is housed in the indoor unit main body 110. The fan 120 generates an air flow.

  The vane 130 is attached to the indoor unit main body 110. The vane 130 adjusts the blowing direction of the airflow.

  The sensor 140 detects the temperature distribution in the room. In the present embodiment, sensor 140 further detects the position of a person in the room.

  The control device 150 estimates the wind speed distribution of the room air from the temperature distribution detected by the sensor 140. The control device 150 controls at least one of the blowout amount and the blowout direction of the airflow adjusted by the fan 120 and the vane 130, respectively, based on the temperature distribution and the wind speed distribution.

  In the present embodiment, the control device 150 determines whether the temperature and the wind speed at the position of the person detected by the sensor 140 are the target temperature and the target wind speed from the temperature distribution and the wind speed distribution, respectively. When it is determined that the temperature and the wind speed at the position of the person are not the target temperature and the target wind speed, the control device 150 corrects at least one of the blowout amount and the blowout direction of the airflow.

  Specifically, the target temperature is a set temperature of the air conditioner. The target temperature can be changed manually using the remote control of the air conditioner.

  Specifically, the target wind speed is a wind speed that a person feels without wind. If the wind speed is below 0.4 meters per second, people feel no wind. Therefore, in the present embodiment, the target wind speed is 0.4 meters per second or less. The target wind speed is set in advance as a range of “0.4 meters / second or less”, or is set in advance as a value such as “0.3 meters / second”.

  In the present embodiment, adjusting the temperature of the person's position to the target temperature has priority over adjusting the wind speed of the person's position to the target wind speed. Therefore, when it is determined that the temperature at the person's position is not the target temperature, the control device 150 adjusts the blowing direction of the airflow to the person's position. On the other hand, when it is determined that the temperature at the person's position is the target temperature, the control device 150 shifts the blowing direction of the airflow from the person's position.

  When the blowing direction of the airflow matches the position of the person, the wind speed at the position of the person exceeds 0.4 meters per second. Therefore, people feel the wind. On the other hand, when the blowing direction of the airflow is deviated from the position of the person, the wind speed at the position of the person is 0.4 meters or less per second. Therefore, people feel no wind. At this time, the temperature at the position of the person is the target temperature. Therefore, a person feels the coolness by cooling or the warmth by heating. That is, a person can obtain satisfaction by feeling coolness or warmth while feeling comfortable by feeling no wind.

  Usually, at the start of heating operation or cooling operation, the temperature at the position of the person is not the target temperature. Therefore, until the controller 150 determines that the temperature at the person's position is the target temperature after the start of the heating operation or the cooling operation, regardless of whether or not the wind speed at the person's position is the target wind speed. And controlling at least one of the blowout amount and the blowout direction of the airflow. Therefore, in the present embodiment, the airflow hits the person until the temperature at the position of the person reaches the target temperature, but thereafter the airflow does not hit the person. As a result, a person can obtain satisfaction by feeling coolness or warmth while feeling comfortable by feeling no wind.

  In the present embodiment, sensor 140 is installed near the left end of the lower surface of indoor unit body 110. The sensor 140 is connected to the control device 150. Specifically, the sensor 140 is an infrared sensor. The sensor 140 is attached in such a direction that the depression angle is about 24.5 degrees. The depression angle is an angle formed by the central axis of the sensor 140 and a horizontal line. That is, the sensor 140 is mounted at an angle of about 24.5 degrees with respect to the horizon. The sensor 140 acquires a thermal image of the room by scanning a certain range of the room while rotating in the left-right direction. The thermal image is an image showing a temperature distribution. When there is a person in the room, the thermal image is also an image showing the position of the person. The sensor 140 may be a camera or a combination of a camera and an infrared sensor.

  In the present embodiment, control device 150 is installed near the left end inside indoor unit main body 110. Specifically, the control device 150 is a control board or a microcomputer mounted on the control board. That is, the control device 150 is implemented by a combination of software and hardware. The hardware includes a processor and a memory. The processor reads the program stored in the memory and executes it to execute the processing of the control device 150. In addition, the processor performs processing of the control device 150 using data stored in the memory, and stores the processing result in the memory. Note that the control device 150 may be implemented only by hardware.

  The control device 150 divides the floor of the room into a plurality of areas. The control device 150 captures the thermal image acquired by the sensor 140. The control device 150 replaces each coordinate point of the thermal image with a plurality of regions. Thereby, the temperature of each area | region of a room, ie, the temperature distribution of a room, is recognized. Further, from which temperature difference between the regions, in which region of the room a person is present, that is, the position of the person in the room is recognized.

  The indoor unit 100 further includes a heat exchanger 160.

  The heat exchanger 160 is a part of the refrigeration cycle in which the refrigerant circulates. The indoor unit 100 supplies the cooled or heated air to the room by using this refrigeration cycle.

  The indoor unit main body 110 is formed with a suction port 111 for sucking room air into the interior and a blowout port 112 for supplying cooled or heated air into the room. The fan 120 sucks room air from the suction port 111. The heat exchanger 160 performs heat exchange between the refrigerant and the indoor air sucked by the fan 120. The fan 120 blows out the air cooled or heated by the heat exchange in the heat exchanger 160 from the outlet 112.

  The suction port 111 is formed in the upper part of the indoor unit main body 110. The outlet 112 is formed in the lower part of the indoor unit main body 110. The fan 20 is installed between the suction port 111 and the blowout port 112. An air path is formed from the fan 20 to the outlet 112. The heat exchanger 160 is installed in the middle of the air path.

  In the present embodiment, the fan 120 includes a plurality of propeller fans 121. The number of propeller fans 121 is two, but can be changed as appropriate. The number of propeller fans 121 is desirably 2 to 4. Each propeller fan 121 is specifically an axial flow fan, but may be changed to a mixed flow fan. A plurality of propeller fans 121 can be changed to one cross flow fan. However, a plurality of propeller fans 121 are preferable from the viewpoints of improving efficiency, increasing the air volume, generating a plurality of independent airflows, and reducing noise.

  The plurality of propeller fans 121 are arranged along the left-right direction of the indoor unit main body 110. Each propeller fan 121 is attached with a motor 122 as a drive source. The plurality of propeller fans 121 are driven independently of each other. Therefore, an independent airflow is generated for each propeller fan 121. That is, an airflow blown from the left side is generated by the left propeller fan 121, and an airflow blown from the right side is generated by the right propeller fan 121.

  All the propeller fans 121 have the same shape and size. By operating all the propeller fans 121 at the same rotational speed, it is possible to obtain substantially the same amount of air flow from all the propeller fans 121. Each propeller fan 121 may have a different size. The number, shape, and size of the propeller fan 121 can be changed as appropriate according to the required air volume and the ventilation resistance inside the indoor unit 100.

  In the present embodiment, the vane 130 includes a plurality of front flaps 131, a plurality of back flaps 132, a plurality of left and right flaps 133, and a plurality of inner vanes 134. The number of front flaps 131 and the number of back flaps 132 are two each, but can be changed as appropriate. The number of front flaps 131 and the number of back flaps 132 are preferably the same. The number of left and right flaps 133 and the number of inner vanes 134 are twelve, but can be changed as appropriate. The number of left and right flaps 133 and the number of inner vanes 134 are preferably the same.

  The plurality of front flaps 131 and the plurality of back flaps 132 are attached to the indoor unit main body 110 so as to cover the air outlet 112 in a state where all the front flaps 131 are closed. The plurality of front flaps 131 are arranged along the left-right direction of the indoor unit main body 110. Each front flap 131 is fixed. The plurality of back flaps 132 are arranged along the left-right direction of the indoor unit main body 110. Each back flap 132 is removable so that the inside of the outlet 112 can be cleaned.

  The plurality of left and right flaps 133 are positioned inside the indoor unit main body 110 with the plurality of front flaps 131 closed, and are positioned outside the indoor unit main body 110 with the plurality of front flaps 131 opened. Attached to the front flap 131. The plurality of left and right flaps 133 are arranged along the left and right direction of the indoor unit main body 110. Each left and right flap 133 is fixed. The plurality of inner vanes 134 are attached to the inside of the indoor unit main body 110 such that the plurality of left and right flaps 133 are positioned above the plurality of left and right flaps 133 in a state where the plurality of left and right flaps 133 are positioned inside the indoor unit main body 110. The plurality of inner vanes 134 are arranged along the left-right direction of the indoor unit main body 110. Each inner vane 134 is fixed.

  The control device 150 controls the rotation speed of the fan 120 and the angle of the vane 130. In the present embodiment, the control device 150 controls the rotation speed of the left propeller fan 121 to adjust the amount of blown air flow on the left side. Similarly, the control device 150 controls the number of rotations of the right propeller fan 121 to adjust the amount of blown air on the right side. The control device 150 controls the angle of the left front flap 131 and the angle of the left back flap 132 to adjust the blowing direction of the left airflow up and down. Similarly, the control device 150 controls the angle of the right front flap 131 and the angle of the right back flap 132 to adjust the blowing direction of the right airflow up and down. The control device 150 adjusts the airflow direction of the left side to the left and right by controlling the angle of the left and right flaps 133 of the left half and the angle of the inner vane 134 of the left half. Similarly, the control device 150 controls the angle of the right half left and right flaps 133 and the angle of the right half inner vane 134 to adjust the right-hand air flow direction to the left and right.

  The control device 150 determines the rotation speed of the fan 120 and the angle of the vane 130 depending on which area of the room the airflow is delivered to. For example, when the airflow is delivered to the left rear area of the room, the control device 150 increases the rotation speed of the left propeller fan 121 to increase the amount of left-side airflow blowout. Further, the control device 150 changes the angle of the left front flap 131, the left back flap 132, the left half left and right flaps 133, and the left half inner vane 134 as necessary. If necessary, the control device 150 can rotate the rotation speed of the right propeller fan 121, the angle of the right front flap 131, the angle of the right back flap 132, the angle of the right and left flaps 133, and the right half inner vane. The angle of 134 is also changed. For example, when the airflow is delivered to the right front area of the room, the control device 150 reduces the rotation speed of the right propeller fan 121 to reduce the amount of airflow blown out on the right side. In addition, the control device 150 changes the angle of the right front flap 131, the angle of the right back flap 132, the angle of the right and left flaps 133, and the angle of the right inner vane 134 as necessary. If necessary, the control device 150 may further adjust the rotation speed of the left propeller fan 121, the angle of the left front flap 131, the angle of the left back flap 132, the angle of the left and right flaps 133, and the left inner vane. The angle of 134 is also changed.

  In the present embodiment, fan 120 is provided upstream of heat exchanger 160. Therefore, the airflow from the fan 120 is rectified by the heat exchanger 160. Therefore, as compared with the configuration in which the fan 120 is provided downstream of the heat exchanger 160, the swirling flow is less likely to be generated in the air blown from the blowout port 112, and the wind speed can be made uniform as a whole. For this reason, the result of airflow control tends to be an expected result. That is, in this embodiment, it becomes easy to appropriately adjust the temperature distribution of the room and the wind speed distribution of the air in the room. In addition, since there is no complicated structure such as the fan 120 at the air outlet 112, it is easy to take measures against condensation that occurs at the boundary between warm air and cold air during the cooling operation. Further, since the motor 122 of the fan 120 is not exposed to the cooled or heated air, a failure is less likely to occur.

  In the present embodiment, the heat exchanger 160 includes a first heat exchanger 161, a second heat exchanger 162, a third heat exchanger 163, and a fourth heat exchanger 164. The heat exchanger 160 is configured such that a longitudinal section cut in the front-rear direction has a W shape as a whole. Note that the triangular gap between the first heat exchanger 161 and the second heat exchanger 162, the triangular gap between the second heat exchanger 162 and the third heat exchanger 163, and the third heat exchanger 163. A heat exchanger may also be installed in one or more of the triangular gaps between the first heat exchanger 164 and the fourth heat exchanger 164. Moreover, the heat exchanger 160 may be configured to be V-shaped by two heat exchangers, or may be configured to have another shape by one or more heat exchangers. The heat exchanger 160 may be configured by an independent heat exchanger for each propeller fan 121. In that case, independent temperature control on the left and right is possible.

  A first heat exchanger 161, a second heat exchanger 162, a third heat exchanger 163, and a fourth heat exchanger 164 are arranged in order from the front side to the back side of the indoor unit main body 110. The first heat exchanger 161 and the third heat exchanger 163 are inclined such that the upper end is closer to the front side of the indoor unit body 110 than the lower end. The second heat exchanger 162 and the fourth heat exchanger 164 are inclined such that the upper end is closer to the back side of the indoor unit body 110 than the lower end. That is, the second heat exchanger 162 and the fourth heat exchanger 164 are inclined in the opposite direction to the first heat exchanger 161 and the third heat exchanger 163. Note that some of the first heat exchanger 161, the second heat exchanger 162, the third heat exchanger 163, and the fourth heat exchanger 164 may be arranged vertically.

  The air passage is divided into a front air passage, a central air passage, and a rear air passage by the heat exchanger 160. The front air path is formed on the front side of the first heat exchanger 161. The central air path is formed between the second heat exchanger 162 and the third heat exchanger 163. The back air path is formed on the back side of the fourth heat exchanger 164.

  Indoor unit 100 further includes a drain pan 170 and a filter 180.

  The drain pan 170 is installed below the heat exchanger 160. The drain pan 170 collects the dew condensation water from the heat exchanger 160.

  In the present embodiment, the drain pan 170 includes a first drain pan 171 and a second drain pan 172. The configuration of the drain pan 170 is appropriately changed according to the configuration of the heat exchanger 160.

  The first drain pan 171 is installed below the first heat exchanger 161 and the second heat exchanger 162. The second drain pan 172 is installed below the third heat exchanger 163 and the fourth heat exchanger 164. When the indoor air is cooled by the heat exchanger 160 during the cooling operation, condensation occurs in the heat exchanger 160. The dew condensation water of the first heat exchanger 161 and the second heat exchanger 162 is dropped from the lower ends of the first heat exchanger 161 and the second heat exchanger 162 and is collected by the first drain pan 171. Condensed water from the third heat exchanger 163 and the fourth heat exchanger 164 is dropped from the lower ends of the third heat exchanger 163 and the fourth heat exchanger 164 and is collected by the second drain pan 172.

  The filter 180 is detachably installed in the suction port 111. The filter 180 prevents dust from entering the interior of the indoor unit 100. The number of filters 180 is two, but can be changed as appropriate. The number of filters 180 is desirably the same as the number of propeller fans 121.

  Note that the indoor unit 100 may be connected to a central controller of a HEMS (home energy management system) by wire or wirelessly. Energy saving effect can be improved by cooperation with HEMS.

*** Explanation of operation ***
With reference to FIG. 8, operation | movement of the indoor unit 100 which the air conditioner which concerns on this Embodiment has is demonstrated. The operation of the control device 150 during the heating operation will be mainly described. The operation of control device 150 corresponds to the airflow control method according to the present embodiment.

  In this airflow control method, the air velocity distribution of the room air is estimated from the temperature distribution of the room detected by the sensor 140 of the air conditioner. Based on the temperature distribution and the wind speed distribution, at least one of the blowing amount and blowing direction of the air flow adjusted by the fan 120 and the vane 130 of the air conditioner is controlled.

  In S11 of FIG. 8, the control device 150 performs normal sensing.

  In normal sensing, the control device 150 rotates the sensor 140 in the left-right direction by 1.6 degrees. The control device 150 stops the sensor 140 for 0.1 to 0.2 seconds each time the sensor 140 is rotated 1.6 degrees. And the control apparatus 150 takes in the thermal image acquired by the sensor 140 in the meantime from the sensor 140. FIG. The movable range of the sensor 140 in the left-right direction is 150.4 degrees. Therefore, when the sensor 140 rotates from one end to the other end of the movable range, the control device 150 obtains 94 thermal images from the sensor 140. These 94 thermal images correspond to detection results of the temperature distribution in the room. In addition, the rotation angle per time of the sensor 140 in normal sensing can be changed as appropriate, and may be set smaller than 1.6 degrees as long as the processing speed of the control device 150 is high. The movable range of the sensor 140 in the left-right direction can also be changed as appropriate, and may be set larger than 150.4 degrees if the processing speed of the control device 150 is fast.

  In S12 of FIG. 8, the control device 150 determines whether there is a person in the room from the thermal image obtained in S11. When it is determined that there is a person in the room, the control device 150 stores the position of the person in the memory. That is, the control device 150 stores the position of the person detected by the sensor 140 in S11 in the memory.

  If it is determined in S12 that there is a person in the room, the flow proceeds to S13. If it is determined in S12 that there is no person in the room, the flow returns to S11.

  In S13 of FIG. 8, the control device 150 determines whether or not the activity amount of the person is small from the history of the position of the person stored in the memory by repeatedly performing S11 and S12. Instead of determining whether the amount of activity of the person is small, it may be determined whether the person is at the same position for a certain time.

  If it is determined in S13 that the amount of human activity is small, the flow proceeds to S14. If it is determined in S13 that the amount of human activity is large, the flow returns to S11.

  In S14 of FIG. 8, the control device 150 performs detailed sensing on the position of the person stored in the memory in S12 and the periphery of the position.

  In the detailed sensing, the control device 150 performs sensing with a resolution four times that of normal sensing. That is, the control device 150 rotates the sensor 140 by 0.4 degrees in the left-right direction. The control device 150 stops the sensor 140 for 0.1 to 0.2 seconds every time the sensor 140 is rotated by 0.4 degrees. And the control apparatus 150 takes in the thermal image acquired by the sensor 140 in the meantime from the sensor 140. FIG. The rotation range in the left-right direction of the sensor 140 in the detailed sensing is 37.6 degrees centering on the position of the person. Therefore, when the sensor 140 rotates from one end to the other end of the rotation range of the detailed sensing, the control device 150 obtains the same number of 94 thermal images as the normal sensing from the sensor 140. Note that the resolution of the detailed sensing can be changed as appropriate, and may be set to five times or more that of normal sensing if the processing speed of the control device 150 is high. The rotation range of the detailed sensing can also be changed as appropriate, and may be set larger than 37.6 degrees if the processing speed of the control device 150 is high.

  In S15 of FIG. 8, the control device 150 determines whether or not the person is warmed up to the hand and toe from the thermal image obtained in S14.

  If it is determined in S15 that the person has not warmed up to the hands and feet, the flow proceeds to S16. If it is determined in S15 that the person has warmed up to the hands and feet, the flow proceeds to S17.

  In S16 of FIG. 8, the control device 150 controls the rotation speed of the fan 120 and the angle of the vane 130 so that the airflow reaches the person's position stored in the memory in S12, that is, the airflow hits the person. To do.

  In S17 of FIG. 8, the control device 150 recognizes the detailed temperature distribution in the vicinity of the position of the person stored in the memory in S12 from the thermal image obtained in S14. The controller 150 estimates the position of the person stored in the memory in S12 and the wind speed distribution of air around the position from the detailed temperature distribution.

  In the present embodiment, the result of statistical processing of the measured data of the temperature distribution and the wind speed distribution is stored in advance in the memory as table format data. This table format data is data for mapping a temperature distribution pattern to a wind speed distribution pattern. The control device 150 refers to this data and converts the detailed temperature distribution around the position of the person and the position into the wind speed distribution. As a method for estimating the wind speed distribution from the temperature distribution, other methods such as using a preset calculation formula may be used in addition to the data in the table format.

  In S18 of FIG. 8, the control device 150 determines the number of rotations of the fan 120 based on the temperature distribution and the wind speed distribution obtained in S15 so that the temperature of the person and the wind speed become the target temperature and the target wind speed, respectively. The angle of the vane 130 is controlled. As described above, the target temperature is specifically the set temperature of the air conditioner. Specifically, the target wind speed is a wind speed that a person feels without wind. That is, the control device 150 controls the rotation speed of the fan 120 and the angle of the vane 130 so that the airflow does not hit the person while the warmth is felt by the person.

  In the present embodiment, the control device 150 searches for the position where the temperature and the wind speed coincide with the target temperature and the target wind speed as the target position from the temperature distribution and the wind speed distribution obtained in S15. The control device 150 calculates the difference between the target position and the person's position. Then, the control device 150 controls the rotational speed of the fan 120 and the angle of the vane 130 so that the position where the airflow reaches is shifted by the same amount as the difference.

  For example, in FIG. 9, it is assumed that the position of a person and the periphery of the position are divided into 28 areas of 4 rows and 7 columns.

  The region A in the third row and the second column and the region B in the third row and the third column are human positions. The person's position is specifically the position of the person's foot. The temperatures in the areas A and B are equal to the target temperature, but the wind speeds in the areas A and B are higher than the target wind speed. On the other hand, the temperature and the wind speed in the region C in the second row and sixth column and the region D in the second row and seventh column respectively match the target temperature and the target wind speed. That is, the area C and the area D are target positions. In this case, the control device 150 adjusts the rotational speed of the fan 120 and the angle of the vane 130 so that the position where the airflow reaches is shifted by the same as the difference between the region C and the region A or the difference between the region D and the region B. Change to correct the amount and direction of air flow. As a result, the temperature distribution and the wind speed distribution in the 28 region surrounded by the solid line in FIG. 9 are shifted to the 28 region surrounded by the alternate long and short dash line in FIG. 9. For this reason, the temperature and the wind speed of the area A and the area B coincide with the target temperature and the target wind speed, respectively.

  Note that if the difference between the region C and the region A or the difference between the region D and the region B is only a difference in the front-rear direction, it is only necessary to change the rotational speed of the fan 120 to adjust the amount of air flow. If the difference between the region C and the region A or the difference between the region D and the region B is only a difference in the left-right direction, it is only necessary to change the direction of the air flow by changing the angle of the vane 130.

*** Explanation of effects ***
In the present embodiment, the air velocity distribution of the room air is estimated from the temperature distribution of the room detected by the sensor 140 of the air conditioner. Based on the temperature distribution and the wind speed distribution, at least one of the blowing amount and blowing direction of the air flow adjusted by the fan 120 and the vane 130 of the air conditioner is controlled. For this reason, according to this Embodiment, it becomes possible to adjust temperature distribution and wind speed distribution appropriately.

  In the present embodiment, it is determined from the temperature distribution and the wind speed distribution whether the temperature and the wind speed at the position of the person are the target temperature and the target wind speed, respectively. If it is determined that it is not, at least one of the blowing amount and the blowing direction of the air current is corrected. For this reason, both comfort and satisfaction can be given to a person.

  In the present embodiment, the target temperature is the set temperature of the air conditioner, and the target wind speed is the wind speed that a person feels no wind. For this reason, the air which cooled or heated can be made to reach | attain a person, without making airflow feel.

  In this embodiment, when it is determined that the temperature at the position of the person is not the target temperature, the direction of the air flow is adjusted to the position of the person. On the other hand, if it is determined that the temperature at the person's position is the target temperature, the direction of the air flow is shifted from the person's position. For this reason, it is possible to prevent the person from feeling an air current in a state where the cooled or heated air is reliably made to reach the person.

  In this embodiment, after starting the heating operation or cooling operation, until it is determined that the temperature of the person's position is the target temperature, regardless of whether the wind speed of the person's position is the target wind speed, Controls at least one of the amount and direction of air flow. For this reason, it is possible to prevent the person from feeling an air current in a state where the cooled or heated air is reliably made to reach the person.

Embodiment 2. FIG.
In Embodiment 1, the position where the airflow blown from the air conditioner is directed is slightly shifted from the position of the person, so that the cooled or heated air reaches the person without feeling the airflow. On the other hand, in this Embodiment, the air which blows off from an air conditioner is extinguished around a person, and the air which cooled or heated reaches | attains a person, without making airflow feel.

  Hereinafter, the configuration of the air conditioner according to the present embodiment, the operation of the air conditioner according to the present embodiment, and the effects of the present embodiment will be described in order. Differences from the first embodiment will be mainly described.

*** Explanation of configuration ***
The configuration of the indoor unit 100 included in the air conditioner according to the present embodiment is the same as that of the first embodiment shown in FIGS.

  As in the first embodiment, the control device 150 estimates the air velocity distribution of the room air from the temperature distribution detected by the sensor 140. The control device 150 controls at least one of the blowout amount and the blowout direction of the airflow adjusted by the fan 120 and the vane 130, respectively, based on the temperature distribution and the wind speed distribution.

  In the present embodiment, the control device 150 controls at least one of the blowout amount and the blowout direction of the airflow, thereby colliding with different surfaces for each airflow among the ceiling surface, the floor surface, and the plurality of wall surfaces of the room. A plurality of airflows that collide with each other at one place in the room later are generated.

  Specifically, the plurality of airflows include an airflow that collides with a wall surface on the left of the indoor unit body 110 among the plurality of wall surfaces, and an airflow that collides with a wall surface on the right of the indoor unit body 110 among the plurality of wall surfaces. Is included.

  As in the first embodiment, the plurality of propeller fans 121 are arranged along the left-right direction of the indoor unit main body 110. The plurality of propeller fans 121 are driven independently of each other. The plurality of airflows are generated by different propeller fans 121 among the plurality of propeller fans 121. That is, the left propeller fan 121 generates an air current that collides with the left wall surface of the indoor unit main body 110, and the right propeller fan 121 generates an air current that collides with the right wall surface of the indoor unit main body 110.

  The control device 150 adjusts the rotation speed of the left propeller fan 121, the angle of the left front flap 131, the angle of the left back flap 132, the angle of the left and right flaps 133, and the angle of the left inner vane 134. Thus, the air flow generated by the left propeller fan 121 is changed to an air current that collides with the wall surface on the left of the indoor unit main body 110. Similarly, the control device 150 determines the rotation speed of the right propeller fan 121, the angle of the right front flap 131, the angle of the right back flap 132, the angle of the right and left flaps 133, and the angle of the right inner vane 134. By adjusting the airflow, the airflow generated by the right propeller fan 121 is changed to an airflow that collides with the wall on the right side of the indoor unit main body 110. The airflow that collided with the wall surface on the left of the indoor unit body 110 and the airflow that collided with the wall surface on the right side of the indoor unit body 110 collide with each other at one place in the room. Thereby, the wind speeds of a plurality of air currents are canceled out, and the periphery of the part is in a state of no air current or near no air current.

  The control device 150 collides the airflow generated by the left propeller fan 121 with the wall surface on the left side of the indoor unit main body 110, and then also collides with the front wall of the indoor unit main body 110, that is, the wall surface behind the room. It is desirable to change to airflow. Similarly, the control device 150 collides the airflow generated by the right propeller fan 121 with the wall on the right side of the indoor unit main body 110 and then on the wall in front of the indoor unit main body 110, that is, the wall behind the room. It is also desirable to change to a colliding airflow. The airflow that collided with the wall surface on the left of the indoor unit body 110 and the airflow that collided with the wall surface on the right side of the indoor unit body 110 both eventually wrap around along the wall surface in the back of the room. collide. Thereby, it can cool and warm so that a person may be wrapped from the circumference with a plurality of air currents.

  The control device 150 adjusts the position where the plurality of airflows collide with each other according to the position of the person detected by the sensor 140.

  In the present embodiment, control device 150 divides the room into a first region including the position of the person, a second region close to the position of the person, and a third region far from the position of the person. The control device 150 adjusts the position where the plurality of airflows collide with each other to the second region.

*** Explanation of operation ***
With reference to FIG. 10, operation | movement of the indoor unit 100 which the air conditioner which concerns on this Embodiment has is demonstrated. The operation of the control device 150 during the heating operation will be mainly described. The operation of control device 150 corresponds to the airflow control method according to the present embodiment.

  In this airflow control method, as in the first embodiment, the air velocity distribution of the room air is estimated from the temperature distribution of the room detected by the sensor 140 of the air conditioner. Based on the temperature distribution and the wind speed distribution, at least one of the blowing amount and blowing direction of the air flow adjusted by the fan 120 and the vane 130 of the air conditioner is controlled.

  In S21 of FIG. 10, the control device 150 performs normal sensing. The process of S21 is the same as the process of S11 of FIG.

  In S22 of FIG. 10, the control device 150 determines whether or not there is a person in the room from the thermal image obtained in S21. The process of S22 is the same as the process of S12 of FIG.

  If it is determined in S22 that there is a person in the room, the flow proceeds to S23. If it is determined in S22 that there is no person in the room, the flow returns to S21.

  In S23 of FIG. 10, the control device 150 recognizes the temperature distribution of the room from the thermal image obtained in S21. The control device 150 estimates the shape of the room from the temperature distribution. As a method for estimating the shape of the room from the temperature distribution of the room, a conventional method can be used. In accordance with the shape of the room, the control device 150 causes the airflow blown from the left side to collide in turn with the left wall surface and the back wall surface of the room, and the airflow blown from the right side The number of rotations of the fan 120 and the angle of the vane 130 are controlled so that the two air currents collide with each other in order, and both air currents collide with each other at one place in the room. That is, the control device 150 controls the rotation speed of the fan 120 and the angle of the vane 130 so that the airflow disappears around the person while the warmth is felt by the person.

  In S24 of FIG. 10, the control device 150 performs normal sensing again. The process of S24 is the same as the process of S11 of FIG. In S24, the control device 150 may perform detailed sensing on the position of the person stored in the memory in S22 and the vicinity of the position. The process in that case is the same as the process in S14 of FIG.

  In S25 of FIG. 10, the control device 150 recognizes the position of the person and the temperature distribution of the room from the thermal image obtained in S24. The control device 150 estimates the air velocity distribution of the room air from the temperature distribution.

  In the present embodiment, as in the first embodiment, the results of statistical processing of the measured data of the temperature distribution and the wind speed distribution are stored in advance in the memory as table format data. This table format data is data for mapping a temperature distribution pattern to a wind speed distribution pattern. The control device 150 refers to this data and converts the temperature distribution of the room into the wind speed distribution. As a method for estimating the wind speed distribution from the temperature distribution, other methods may be used as in the first embodiment.

  In S26 of FIG. 10, the control device 150 searches for a position where the plurality of airflows blown out in S23 collide with each other from the temperature distribution and the wind speed distribution obtained in S25. Specifically, the control device 150 has the lowest wind speed among the position where the temperature is highest with respect to other positions or the position where the temperature is relatively high with respect to other positions. The position is detected as a collision position. Further, the control device 150 sets a position where a plurality of airflows should collide with each other around the position of the person as a target position. Specifically, the control device 150 includes a region adjacent to a region where a person is present among a plurality of regions in a room, or a region where a person is sandwiched between another region and a region where a person is present. An area far from the area, that is, an area next to an area where a person is present is determined as a target position. The control device 150 calculates the difference between the collision position and the target position. The controller 150 does nothing if there is no difference. On the other hand, if there is a difference, the control device 150 controls the rotation speed of the fan 120 and the angle of the vane 130 so that the position where the airflow collides is shifted by the same amount as the difference.

  For example, in FIG. 11, it is assumed that a room is divided into 35 areas of 5 rows and 7 columns.

  Region A in the second row and third column is the position of a person. Region B in the fifth row and fourth column is a collision position. Since the distance between the area A and the area B is long, a person is not feeling warmth. For this reason, it is necessary to collide a plurality of air currents in the area around the area A, such as the area C in the third row and the third column. In this case, the control device 150 changes the rotation speed of the fan 120 and the angle of the vane 130 so that the position where the air current collides is shifted by the same amount as the difference between the region B and the region C. Correct the blowing direction. As a result, a plurality of air currents collide around the area A where people are present. For this reason, the temperature and the wind speed in the region A coincide with the target temperature and the target wind speed, respectively. Similar to the first embodiment, the target temperature is specifically the set temperature of the air conditioner. Specifically, the target wind speed is a wind speed that a person feels without wind. That is, the target wind speed is 0.4 meters per second or less.

  Region A corresponds to the first region described above. Region B corresponds to the third region described above. Region C corresponds to the second region described above. In the above example, the control device 150 adjusts the position where the plurality of airflows collide with each other to the second region.

  If the difference between the regions B and C is only the difference in the front-rear direction, it is only necessary to change the rotational speed of the fan 120 and adjust the amount of blown airflow. If the difference between the region B and the region C is only a difference in the left-right direction, it is only necessary to change the direction of the air flow by changing the angle of the vane 130.

  As a modification of the present embodiment, the control device 150 may omit the process of estimating the air velocity distribution of the room air. That is, the control device 150 may control at least one of the blowout amount and the blowout direction of the airflow adjusted by the fan 120 and the vane 130, respectively, based only on the temperature distribution in the room. Further, the sensor 140 may be omitted. In that case, the position where the plurality of airflows collide with each other cannot be adjusted according to the position of the person detected by the sensor 140. However, the airflow that collided with the wall surface on the left of the indoor unit main body 110 and the airflow that collided with the wall surface on the right of the indoor unit main body 110 are caused to collide with each other in such a way as to wrap around the wall surface in the back of the room. Thus, it is possible to obtain a certain effect that the whole room can be cooled or warmed so as to be wrapped.

*** Explanation of effects ***
In the present embodiment, similarly to the first embodiment, the air velocity distribution of the room air is estimated from the temperature distribution of the room detected by the sensor 140 of the air conditioner. Based on the temperature distribution and the wind speed distribution, at least one of the blowing amount and blowing direction of the air flow adjusted by the fan 120 and the vane 130 of the air conditioner is controlled. For this reason, according to this Embodiment, it becomes possible to adjust temperature distribution and wind speed distribution appropriately.

  In the present embodiment, the two air streams blown out from the indoor unit 100 are caused to collide with each other around the person, thereby eliminating the air streams. Therefore, it is possible to form a space that does not let a person feel the airflow.

  According to the present embodiment, it is possible to remove the discomfort caused by the wind hitting a person and to give satisfaction to the person by sending cooled or heated air.

  In the conventional air conditioning, the cooled or heated air blown from the indoor unit reaches a person and then diffuses into the room. For this reason, the change in the temperature around the person becomes gradual. Therefore, it takes time for the temperature around the person to reach the target temperature. When conventional windbreak control is performed, the cooled or heated air cannot be sent directly to a person. Therefore, similarly, it takes time for the temperature around the person to reach the target temperature. In contrast, in the present embodiment, one of the cooled or heated air blown out from the indoor unit 100 flows so as to push the other air back. Therefore, the cooled or heated air stays around the person. Therefore, the temperature around the person can reach the target temperature in a short time. As a result, energy loss in air conditioning can be suppressed.

  When heating and cooling the entire room, very large electric power is required. On the other hand, in this Embodiment, the air cooled or heated can be concentrated around a person and power consumption can be suppressed to the minimum. Therefore, when the use restriction of the power consumption such as peak cut is performed, the power used for the air conditioner can be minimized and the remaining power can be passed to other devices.

  In the present embodiment, the position where the air current collides and disappears can be changed according to the position of the person.

  When the door of the room is opened and the room is expanded, the position of the inner wall becomes far and the position where the air current collides changes. However, in this embodiment, it is possible to detect a change in the position where the air current collides from the temperature distribution in the room. Then, the position where the air current collides can be moved again to an appropriate position by controlling at least one of the air flow amount and the air blowing direction.

  In the present embodiment, even if there is an obstacle between the indoor unit 100 and the person, the obstacle can be bypassed by using an air flow that wraps the person from the surroundings.

Embodiment 3 FIG.
The configuration of the air conditioner according to the present embodiment, the operation of the air conditioner according to the present embodiment, and the effects of the present embodiment will be described in order. Differences from the second embodiment will be mainly described.

*** Explanation of configuration ***
The configuration of the indoor unit 100 included in the air conditioner according to the present embodiment is the same as that of the first embodiment shown in FIGS.

  As in the first embodiment, the control device 150 determines whether the temperature and the wind speed at the position of the person detected by the sensor 140 are the target temperature and the target wind speed from the temperature distribution and the wind speed distribution, respectively. When it is determined that the temperature and the wind speed at the position of the person are not the target temperature and the target wind speed, the control device 150 corrects at least one of the blowout amount and the blowout direction of the airflow.

Similar to the first embodiment, the target temperature is specifically the set temperature of the air conditioner. Specifically, the target wind speed is a wind speed that a person feels without wind. That is, the target wind speed is 0.4 meters per second or less.

  If it is determined in S36 that the temperature and wind speed at the person's position are the target temperature and the target wind speed, respectively, the flow ends. If it is determined in S36 that the temperature and the wind speed at the position of the person are not the target temperature and the target wind speed, the flow proceeds to S37.

  The process of S37 in FIG. 12 is the same as the process of S26 in FIG. Instead of the process of S37, the same process as S18 of FIG. 8 may be performed. That is, the control device 150 searches the temperature distribution and the wind speed distribution obtained in S35 for a position where the temperature and the wind speed coincide with the target temperature and the target wind speed as the target position, and the difference between the target position and the human position. The rotational speed of the fan 120 and the angle of the vane 130 may be controlled so that the position where the air current collides is shifted by the same amount as the above.

*** Explanation of effects ***
In the present embodiment, the same effect as in the second embodiment can be obtained.

  As in the second embodiment, the control device 150 controls at least one of the blowout amount and the blowout direction of the airflow, so that the surface of the room differs among the airflow among the ceiling surface, the floor surface, and the plurality of wall surfaces. A plurality of airflows that collide with each other at one place in the room after the collision is generated.

  Specifically, the plurality of airflows include an airflow that collides with the ceiling surface and an airflow that collides with the floor surface.

  As in the second embodiment, the plurality of propeller fans 121 are arranged along the left-right direction of the indoor unit main body 110. The plurality of propeller fans 121 are driven independently of each other. The plurality of airflows are generated by different propeller fans 121 among the plurality of propeller fans 121. That is, one of the airflow colliding with the ceiling surface of the indoor unit body 110 and the airflow colliding with the floor surface is generated by the left propeller fan 121, and the other airflow is generated by the right propeller fan 121. The

Similarly, the control device 150 adjusts the number of rotations of the right propeller fan 121, the angle of the right front flap 131, and the angle of the right back flap 132, so that the airflow generated by the right propeller fan 121 is Change to the other airflow. The airflow that collided with the ceiling surface and the airflow that collided with the floor surface collide with each other at one place in the room. Thereby, the wind speeds of a plurality of air currents are canceled out, and the periphery of the part is in a state of no air current or close to no air current.

  The control device 150 changes the airflow generated by the left propeller fan 121 into an airflow that collides with the front surface of the indoor unit main body 110, that is, the wall in the back of the room, after colliding with the ceiling surface or the floor surface. Is desirable. Similarly, the control device 150 collides the airflow generated by the propeller fan 121 on the right side with the floor surface or the ceiling surface, and then collides with the front wall of the indoor unit main body 110, that is, the wall surface behind the room. It is desirable to change to Both the airflow that collided with the ceiling surface and the airflow that collided with the floor surface finally collide with each other in such a way as to wrap around along the wall surface in the back of the room. Thereby, it can cool or warm so that a person may be wrapped up and down with a plurality of air currents.

*** Explanation of operation ***
The operation of the indoor unit 100 included in the air conditioner according to the present embodiment is the same as that of the second embodiment shown in FIG. 10 except for the processing of S23.

  In S23, the control device 150 causes the airflow blown from the left side in order to collide with the ceiling surface of the room and the back wall of the room in order, and the airflow blown from the right side in turn to the floor of the room and the wall of the back of the room. The rotational speed of the fan 120 and the angle of the vane 130 are controlled so that both airflows collide with each other at one place in the room. Alternatively, the control device 150 causes the airflow blown from the left side to collide with the floor surface of the room and the wall surface in the back of the room in order, and the airflow blown from the right side in turn to the ceiling surface of the room and the wall surface of the back of the room in order. The rotation speed of the fan 120 and the angle of the vane 130 are controlled so that the two airflows collide with each other at one place in the room.

  As a modification of the present embodiment, the control device 150 may omit the process of estimating the air velocity distribution of the room air. That is, the control device 150 may control at least one of the blowout amount and the blowout direction of the airflow adjusted by the fan 120 and the vane 130, respectively, based only on the temperature distribution in the room. Further, the sensor 140 may be omitted. In that case, the position where the plurality of airflows collide with each other cannot be adjusted according to the position of the person detected by the sensor 140. However, the airflow that collided with the ceiling surface and the airflow that collided with the floor surface collide with each other in such a way as to wrap around the wall surface at the back of the room, so that the entire room can be cooled or warmed A certain effect that it can be obtained.

*** Explanation of effects ***

Embodiment 5. FIG.
In Embodiment 1, the position where the airflow blown from the air conditioner is directed is slightly shifted from the position of the person, so that the cooled or heated air reaches the person without feeling the airflow. On the other hand, in the present embodiment, the airflow blown out from the air conditioner collides with an obstacle around the person and disappears, so that the air cooled or heated is not given to the person without feeling the airflow. To reach.

  Hereinafter, the configuration of the air conditioner according to the present embodiment, the operation of the air conditioner according to the present embodiment, and the effects of the present embodiment will be described in order. Differences from the first embodiment will be mainly described.

*** Explanation of configuration ***
The configuration of the indoor unit 100 included in the air conditioner according to the present embodiment is the same as that of the first embodiment shown in FIGS.

  In the present embodiment, the sensor 140 detects the position of an obstacle around the position of the person in addition to the position of the person in the room. Obstacles include sofas, tables, and chairs.

  The control device 150 adjusts the direction of the airflow to the position of the obstacle detected by the sensor 140. Specifically, the control device 150 adjusts the rotational speed of the fan 120 and the angle of the vane 130, thereby causing the airflow generated by the fan 120 to collide with obstacles around the person's position. Change to When the air current collides with the obstacle, the wind speed of the air current is greatly reduced at the position of the obstacle. Therefore, the position of the person near the obstacle becomes a state of no airflow or no airflow.

*** Explanation of operation ***
With reference to FIG. 13, the operation | movement of the indoor unit 100 which the air conditioner which concerns on this Embodiment has is demonstrated. The operation of the control device 150 during the heating operation will be mainly described.

  The processes in S51 to S56 in FIG. 13 are the same as the processes in S11 to S16 in FIG.

  In S57 of FIG. 13, the control device 150 recognizes the position of the obstacle around the position of the person from the thermal image obtained in S51. The control device 150 controls the rotation speed of the fan 120 and the angle of the vane 130 so that the airflow collides with the obstacle. That is, the control device 150 controls the rotation speed of the fan 120 and the angle of the vane 130 so that the airflow disappears around the person while the warmth is felt by the person.

  In S58 of FIG. 13, the control device 150 performs normal sensing again. The process of S58 is the same as the process of S11 of FIG. In S58, the control device 150 may perform detailed sensing on the position of the person stored in the memory in S52 and the vicinity of the position. The process in that case is the same as the process in S14 of FIG.

  In S59 of FIG. 13, the control device 150 recognizes the position of the person and the temperature distribution of the room from the thermal image obtained in S58. The control device 150 estimates the air velocity distribution of the room air from the temperature distribution.

  In the present embodiment, as in the first embodiment, the results of statistical processing of the measured data of the temperature distribution and the wind speed distribution are stored in advance in the memory as table format data. This table format data is data for mapping a temperature distribution pattern to a wind speed distribution pattern. The control device 150 refers to this data and converts the temperature distribution of the room into the wind speed distribution. As a method for estimating the wind speed distribution from the temperature distribution, other methods may be used as in the first embodiment.

  In S60 of FIG. 13, the control device 150 confirms from the temperature distribution and wind speed distribution obtained in S59 whether or not the airflow blown out in S57 collides with an obstacle, and rotates the fan 120 as necessary. The number and the angle of the vane 130 are changed.

  As a modification of the present embodiment, the control device 150 may omit the process of estimating the air velocity distribution of the room air. That is, the process of S60 may be omitted. Even in that case, if the position of the obstacle is known, the airflow can be blown out toward the obstacle with a certain degree of accuracy. Accordingly, by causing the airflow to collide with the obstacle, a certain effect that the position of the person near the obstacle can be brought into a state of no airflow or no airflow can be obtained.

*** Explanation of effects ***
In the present embodiment, similarly to the first embodiment, the air velocity distribution of the room air is estimated from the temperature distribution of the room detected by the sensor 140 of the air conditioner. Based on the temperature distribution and the wind speed distribution, at least one of the blowing amount and blowing direction of the air flow adjusted by the fan 120 and the vane 130 of the air conditioner is controlled. For this reason, according to this Embodiment, it becomes possible to adjust temperature distribution and wind speed distribution appropriately.

  As mentioned above, although embodiment of this invention was described, you may implement combining some of these embodiment. Alternatively, any one or some of these embodiments may be partially implemented.
