Embodiment 1 FIG.
FIG. 1 is an explanatory diagram showing an outline of a room in which the air-conditioning / air-blowing control device 10 according to Embodiment 1 is installed and the configuration of the air-conditioning / air-blowing control device 10. The indoor unit 20 is installed in the room 30, and the air-conditioning / air-blowing control device 11 is based on information from the sensor 24 provided in the indoor unit 20 and at least the blower 22 constituting the indoor air blower and the wings 23 as the wind direction plate. Control one. By setting a fixed position where a person is located and detecting that the presence / absence state of the person at this fixed position has changed to absent, the air conditioning and air blow control device 11 performs control so that air is blown to the fixed position. , Heated or cooled air is circulated by sending it to a place where a person may be steadily located and when no one is present, thereby wasting the heated or cooled air It is a combination of comfort and efficiency.

  First, the configuration of the indoor unit 20 will be described. The indoor unit 20 includes a decorative panel 21, a blower 22 and a wing 23 that constitute an indoor blower, a sensor 24, and a communication interface 25.

  The decorative panel 21 is a housing of the indoor unit 20, and has a suction port that sucks in air in the room 30 and a blowout port that blows out the sucked air into the room 30.

An indoor air blower is comprised by the air blower 22 and the wing | blade 23, and controls ventilation intensity | strength and a ventilation direction.
The blower 22 is composed of a fan and a motor. When the fan is rotated by the motor, an air flow from the suction port of the decorative panel 21 to the blower outlet is generated, and the airflow warmed by the heat exchanger or the heater provided between the suction port and the blower outlet is generated from the blower outlet. Be blown. The blowing intensity is controlled by the number of rotations of the motor.
Further, the wings 23 are constituted by a plate-like panel provided at the blowout port of the decorative panel 21 and a motor. Since the airflow generated by the blower 22 is blown out along the panel, the blowing direction is controlled by driving the motor to change the angle of the panel. The variable range of the blowing direction can be arbitrarily set by the number of panels, the direction, the number of motors, and the like.

  The sensor 24 is provided on the lower surface of the decorative panel 21 of the indoor unit 20 and is configured by an element that can detect the temperature of the room, for example, a thermosensor.

  The communication interface 25 communicates with the communication interface 15 of the air conditioning blower control device 10. The communication interface 25 transmits information on the room temperature detected by the sensor 24 to the communication interface 15 of the air conditioning blow control device 10 and receives a command from the communication interface 15 from the air conditioning blow control device 10. The communication method between the communication interface 25 of the indoor unit 20 and the communication interface 16 of the air conditioning blower control device 11 may be wired or wireless.

  Next, the configuration of the air conditioning blow control device 10 will be described.

The fixed position setting means 11 sets a fixed position where a person is located in the room 30 provided with the indoor air blower of the indoor unit 20 of the air conditioner. Here, the fixed position is a place where a person may stay for a certain time, for example, a position of a seat decided indoors or a position where a person often stays. In addition, even if the position of the seat is determined on the coordinates in the room, it does not necessarily have to be a fixed position. For example, a seat that is known to be a hollow seat for a day does not have to be a fixed position.
FIG. 2 is a configuration diagram showing a detailed configuration of the home position setting means 11. The fixed position setting unit 11 includes a difference calculation unit 111, a presence / absence information generation unit 112, a storage unit 113, and a fixed position determination unit 114.

The difference calculation unit 111 issues a temperature detection command to the sensor 24 of the indoor unit 20 through the communication interface 15 of the air conditioning and ventilation control device 10 and the communication interface 26 of the indoor unit 20, and acquires temperature information of the room 30 from the sensor. Further, the difference calculation unit 111 generates temperature distribution information of the room 30 based on the acquired temperature information. FIG. 3 shows table information as an example of temperature distribution information. This table information indicates the temperature (° C.) measured for each region by dividing the plane viewed from the sensor 24 vertically and horizontally, with the horizontal axis as the x direction and the vertical axis as the y direction. A table as shown in FIG. 3 is generated in the difference calculation unit 111 based on temperature information including the temperature measured by the sensor 24 and the measurement position based on a command from the air-conditioning / air-blowing control device 10. Two types of table information are generated: a base information table composed of base information and a latest information table composed of the latest information. Each area in each table is assigned one value that represents the area. This representative value may be obtained by averaging values such as temperature in each area, or may be specified within the area. It may be a point value.
The base information is temperature information that is an initial value when extracting a change in temperature distribution, and is preferably measured in the absence of a person in the room 30, for example, in the early morning before a person goes to work in the office. It is set to be measured and is updated regularly at a daily cycle. The latest information is current temperature distribution information of the room 30 including the person, and is updated periodically, for example, at a cycle of 30 seconds. The difference calculation unit 111 first acquires base information and generates and stores a base information table. Next, the latest information is acquired and the latest information table is generated and stored. Then, for each region, the difference between the stored base information and the acquired latest information is calculated. FIG. 4 illustrates an example of a difference information table including difference information obtained by calculating a difference when the base information illustrated in FIG. 3 and the latest information are acquired. The calculated difference information is output to the presence / absence information generation unit 112 every 30 seconds.
The time for acquiring the base information and the time interval for acquiring the latest information from the sensor 24 are set by the user, for example, and are not limited to the above-described time.

When the difference information is acquired, the presence / absence information generation unit 112 generates the presence / absence information when the difference is equal to or greater than the set threshold value, with the position as the position where the person exists. When the person comes to each region, the temperature rises and the difference becomes large. For example, the threshold is set to 15.0 or more, and if the difference is 15.0 or more, it is determined that the person is present. The value of position presence / absence information is set to 1. If the difference is less than 15.0, it is determined that the person is absent, and the value of the presence / absence information of the position is set to 0. FIG. 5 shows an example of a presence / absence information table including presence / absence information generated based on the difference information shown in FIG. 4 acquired from the difference calculation unit 111 by the presence / absence information generation unit 112. The presence / absence information generation unit 112 outputs the generated presence / absence information to the storage unit 113.
Note that the threshold can be changed by setting, and is not limited to the above as long as it is a threshold that can detect a person from the difference information between the base information and the latest information.

The storage unit 113 acquires the presence / absence information table from the presence / absence information generation unit 112 and stores it. The storage unit 113 stores up to 120 presence / absence information tables corresponding to one hour, and when more presence / absence information tables are acquired, the storage unit 113 sequentially updates from the oldest one.
The number of presence / absence information tables stored in the storage unit 113 is set by the user and is not limited to 120.

For each area of the presence / absence information table stored in the storage unit 113, the fixed position determination unit 114 has a value of 1 or more of the presence / absence information of 1 in 120, that is, an area that is in the presence state is a fixed position. Set and generate home position information. FIG. 6 shows an example of a fixed position information table including fixed position information indicating the set fixed positions.
Note that the number of presence / absence information for determining the fixed position in the fixed position determination unit 114 is set by the user, and is not limited to the number described above. The detailed configuration of the home position setting unit 11 has been described above.

The presence / absence detection unit 12 detects the presence / absence of a person at the fixed position set by the fixed position setting unit 11. The presence / absence detection unit 12 first acquires presence / absence information from the presence / absence information generation unit 112 of the fixed position setting unit 11 and the fixed position information from the fixed position determination unit 114, and the position set as the fixed position by the fixed position information. The presence / absence information is detected using the presence / absence information to generate home position information.
The presence / absence detection of a person at a fixed position is performed as follows. First, the position where the fixed position information is 0 is a position that is not set as a fixed position in the first place, and the value of the fixed position presence / absence information is set to 0 so that it is not determined as a blow target position to be described later. Further, a position where the value of the fixed position information is 1 and the value of the presence / absence information is 1, the value of the fixed position presence / absence information is 1. Furthermore, the value of the fixed position presence / absence information is 0 for the position where the value of the fixed position information is 1, but the value of the presence / absence information is 0 indicating the absence. FIG. 7 shows an example of the fixed position presence / absence information table when the fixed position presence / absence information is generated based on the presence / absence information table acquired from the storage unit 113 by the presence / absence detection unit 12 and the fixed position information table of FIG. . The home position presence / absence information table generated by the presence / absence detection unit 12 is output to the absence detection unit 13.

  The absence detection means 13 detects that the presence / absence state of the home position detected by the presence / absence detection means 12 as a person is changed to the absence state. Specifically, the absence detection unit 13 stores 20 fixed position presence / absence information tables output by the presence / absence detection unit 12 corresponding to the latest 10 minutes of information. When the number of fixed position presence / absence information tables to be stored exceeds 20, the old fixed position presence / absence information is sequentially updated to a new fixed position presence / absence information table. The absence detection means 13 detects whether there are 10 or more consecutive zeros indicating the absence state for each position in the stored 20 fixed position presence / absence information tables. Among them, it is detected whether there are 5 or more 1s indicating the existence state other than 10 consecutive 0s. And when these conditions are satisfy | filled, it will detect that the presence / absence state of the fixed position changed to the absent state, and the fixed position absence information will be output to a ventilation condition setting means. This means that the presence / absence state of the home position is changed to the absence state when the place where the home position is set continues for 10 minutes without a person for 5 minutes.

The air blowing condition setting means 14 sets the air blowing direction of the indoor air blower determined corresponding to the fixed position where the absence detection means 13 detects that the presence / absence state has changed to the absence state. Specifically, based on the fixed position absence information output from the absence detection means 13, in order to blow the air to the center of the position where the presence / absence state of the fixed position has changed to the absent state, the motor of the wing 23 of the indoor blower is used. Set the control conditions. In FIG. 9, the outline | summary of the example of a setting of ventilation conditions is shown. The detected position and the angle of the panel controlled by the motor are stored in the blowing condition setting means 14 as table information. In order to blow to the center of the position where the fixed position presence / absence state has changed to the absence state, the angle of the panel of the wing 23 to blow into the “absence” range shown in FIG. Is controlled to the median value of the angle α shown in FIG. The air blowing condition setting unit 14 outputs the set air blowing conditions to the communication interface 15.
In addition, the panel angle of the wing 23 set by the blowing condition setting means 14 is not limited to the panel extending line extending to the area where the wing 23 is absent. Any angle that blows air to the region may be used.

  The communication interface 15 transmits to the communication interface of the indoor unit 20 under the blowing condition set by the blowing condition setting means 14. Based on the sent air blowing conditions, the motor of the wing 23 is controlled to perform air blowing control.

  Next, operation | movement of the air-conditioning ventilation control apparatus 10 which concerns on this Embodiment 1 is demonstrated. FIG. 10 is a flowchart showing the operation of the air-conditioning blow control apparatus 10 according to the first embodiment.

In step S <b> 1, the fixed position setting unit 11 issues a command to the sensor 24 and acquires temperature information from the sensor 24. The fixed position setting means 11 generates base information and latest information from the acquired temperature information, generates and stores presence / absence information of the room 30 from the difference between the base information and the latest information, and a person exists at the same position for a certain time or more. The position in the state is set as a fixed position, and the fixed position information is output to the presence / absence detecting means.
In step S <b> 2, the presence / absence detection unit 12 acquires the presence / absence information detected by the presence / absence detection unit 12 of the fixed position setting unit 11 and the fixed position information set by the fixed position determination unit 114. The presence / absence information is acquired every predetermined time. Further, the presence / absence information and the fixed position information are compared to detect the presence / absence of a person at the fixed position.

FIG. 11 is a flowchart showing the detailed operation of the fixed position setting means 11.
Steps S <b> 11 to S <b> 13 show the operation of the difference calculation unit 111 of the fixed position setting unit 11. In step S11, the difference calculation unit 111 issues a command to the sensor 24, acquires a temperature information table serving as a base of the room 30, and generates a base information table. The difference calculation unit 111 stores the base information table, and proceeds to step S12 after 30 seconds have elapsed since the generation of the base information table. In step S12, the difference calculation unit 111 issues a command to the sensor 24 every 30 seconds to acquire the current temperature information in the room 30, and generates a latest information table. In step S <b> 13, the difference calculation unit 111 calculates a temperature distribution difference between the base information table acquired in step S <b> 11 and the latest information table acquired in step S <b> 12 and outputs the difference to the presence determination unit 112. The difference calculation unit 111 outputs the difference information table between the base information table and the latest information table to the presence determination unit 112 every 30 seconds in order to acquire the latest information table every 30 seconds in step S12.
In step S14, the presence / absence detection unit 112 acquires the difference information table calculated in step S13, detects whether there is a person in the room 30 based on a threshold value from the difference information table at each position, A presence / absence information table is output to the storage unit 113. There is an upper limit on the number of presence / absence information tables stored in the storage unit 113, and a maximum of 120 presence / absence information tables are stored. When more presence / absence information tables are input, old ones are updated sequentially. .
In step S15, the fixed position determination unit 114 detects positions where 60 or more people are detected at the same position in the plurality of presence / absence information tables stored in the storage unit 113, determines the fixed position, and determines the fixed position information. Generate a table.

When the fixed position is set as described above, in step S3, the absence detecting unit 13 acquires and stores 20 fixed position presence / absence information tables generated by the presence / absence detecting unit 12, and also stores the fixed position presence / absence information. At each position in the table, it is detected whether there are 10 or more consecutive 0s indicating the absence state. If there are, there are 5 or more 1 indicating the presence state other than the 10 consecutive 0s. By detecting the presence, it is determined whether there is a position where the presence / absence state has changed to the absence state. If it is not detected that the presence / absence state has changed to the absence state, the process returns to step S2. If it is detected that the presence / absence state has changed to the absence state, the process proceeds to step S4.
In step S <b> 4, the blowing condition setting unit 14 sets the blowing direction to the center of the position where the presence / absence state has changed to the absence state based on the fixed position absence information table generated by the absence detection unit 13. Set the ventilation conditions of the indoor blower.
In step S5, the blowing condition setting means 14 sends the set blowing condition to the indoor unit 20 via the communication interface 15 and the communication interface 25, and the motor of the blade 23 is controlled thereby to control the blowing.

  By the above-described operation, a command related to the blowing condition of the indoor unit 20 is received by the communication interface of the indoor unit 20, and the indoor blower operates according to the commanded blowing condition. In the present embodiment, since the condition of the panel angle of the wings 23 is commanded by the air conditioning blow control device 10, the angle of the panel is changed by controlling the motor, and the blower is sent to the position where the presence / absence state is changed to the absence state. Will come to be.

  As described above, according to the air-conditioning blow control apparatus according to Embodiment 1, a fixed position where a person is located is set, and it is detected that the presence / absence state of the person at the fixed position has changed to absence, and the indoor blower blows air. By setting the air blowing condition including at least one of the air blowing intensity and the air blowing angle, the position where the air is blown when a person is absent is a fixed position that is originally assumed to have a person, so It can be suppressed that the adjusted air is continuously sent to a place where a person is not in a steady state and is wasted. Thereby, a comfortable environment can be provided by blowing the air-conditioned wind to the position where the person exists again. In addition, since the air blowing direction is directed to the position where the presence / absence state has changed to the absence state, it is possible to blow air toward the floor compared to the direction horizontal to the ceiling to avoid air blowing to the person, Heating efficiency rises compared with the case where it continues blowing in the direction.

  In addition, although the sensor 24 demonstrated the element which can detect temperature, for example, what is comprised with a thermo sensor, as long as the position of the presence or absence state of the person in the room 30 is known, another sensor may be used.

  In addition, the fixed positions set by the fixed position setting unit 11 are set to be sequentially updated. However, once the fixed position is set, the fixed position information may be continuously used.

Embodiment 2. FIG.
Next, the air conditioning blower control apparatus 10 according to Embodiment 2 will be described. In the first embodiment, the fixed position information and presence / absence information are detected by the sensor 24. However, in the second embodiment, the fixed position is set in advance and the presence / absence is detected by the gate 26 provided at the entrance / exit of the room 30. explain.
In the second embodiment, the detailed configurations and operations of the fixed position setting unit 11, the presence / absence detecting unit 12, and the gate 26 are different from those of the first embodiment, and other configurations and operations are the same as those of the first embodiment.

FIG. 12 is a configuration diagram of the air-conditioning air blow control apparatus 10 according to the second embodiment.
The gate 26 is provided at the entrance / exit of the room 30 and manages the entrance / exit of the person in the room 30. The entrance / exit indicating who entered / exited the room 30 by touching the gate with a card having personal information. Generate information. Based on this entry / exit information, it may be determined whether a person is at his or her seat. This entrance / exit information is output as presence / absence information to the communication interface 15 of the air-conditioning / air-blowing control device 10 through a communication interface (not shown).

  The fixed position setting means 11 sets a fixed position where a person is located in the room 30 where the indoor air blower of the indoor unit 20 is provided. The fixed position is set by inputting in advance which position corresponds to which fixed position based on the personal information of the card by the user. The set home position information is output to the presence / absence detecting means 12.

  The presence / absence detection unit 12 detects the presence / absence of a person at the fixed position set in the fixed position setting unit 11. The presence / absence detection means 12 acquires the fixed position information from the fixed position setting means 11 and the presence / absence information from the communication interface 15, and the presence / absence information on the presence / absence of the person at the position set as the fixed position by the fixed position information. Is used to generate home position presence / absence information. The presence / absence information generated by the presence / absence detection unit 12 is output to the absence detection unit 13. Subsequent operations are the same as those in the first embodiment.

As described above, according to the air-conditioning blow control apparatus according to the second embodiment, a fixed position where a person is located is set, and it is detected that the presence / absence state of the person at the fixed position has changed to absence. By setting at least one of the blowing intensity and the blowing angle to be performed, it is possible to prevent the air that has been adjusted as in the past from being continuously sent to a place where a person is not steadily wasted and wasted. In addition, since the air blowing direction is directed to the position where the presence / absence state has changed to the absence state, it is possible to blow air toward the floor compared to the direction horizontal to the ceiling to avoid air blowing to the person, Heating efficiency rises compared with the case where it continues blowing in the direction.
In the second embodiment, since the fixed position information is set by human input, an accurate fixed position can be grasped. Furthermore, since the presence / absence information of the person is generated by detecting the person's entrance / exit by the gate 26, more reliable presence / absence information is obtained compared to the sensor 24.

  In the second embodiment, the presence / absence information is generated by the gate 26. However, the presence / absence information can be obtained in correspondence with the fixed position information. The presence / absence may be detected and input by software installed on a personal computer.

  In the second embodiment, the fixed position information is input to the fixed position setting unit 11 and the presence / absence information is generated by the gate 26. However, the presence / absence information is detected by the sensor 24 as in the first embodiment. Also good.

  In the above embodiment, the case where only the blowing direction depending on the angle of the panel is set as the blowing condition is described. However, the blowing intensity of the blower may be set as the blowing condition, and both the blowing intensity and the blowing direction are set. It may be set. When the air blowing conditions are set according to the air blowing intensity and the air blowing direction, it is realized by setting the control of the wing 23 that determines the air blowing direction as a swing and the fan control that determines the air blowing intensity according to the air blowing direction is set to be switched ON and OFF. To do.

Embodiment 3 FIG.
Next, the air conditioning blower control apparatus 10 according to Embodiment 3 will be described. In the first embodiment, the blowing direction of the blowing condition set by the blowing condition setting unit 14 is one direction. However, in the third embodiment, the wing 23 is within the range that is not present in the home position absence information. Swing.
In this Embodiment 3, the detailed structure of the ventilation condition setting means 14 differs from Embodiment 1, and the other structure and operation | movement are the same as that of Embodiment 1. FIG.

The air blowing condition setting means 14 sets the air blowing direction of the indoor air blower determined corresponding to the fixed position where the absence detection means 13 detects that the presence / absence state has changed to the absence state. Specifically, on the basis of the fixed position absence information output from the absence detecting means 13, the room is used to swing and blow the air to a certain range toward the position where the presence / absence state of the fixed position has changed to the absent state. Conditions for controlling the motor of the wing 23 of the blower are set. The detected position and the angle of the panel controlled by the motor are stored in the blowing condition setting means 14 as table information. The range of the swing differs depending on the detection range of the presence / absence information.
FIG. 13 is a conceptual diagram in which the home position absence information detected by the absence detector 13 of the air-conditioning / air-blowing control device 10 according to the third embodiment is represented in one dimension. The fixed position absence information in this case is expressed in a one-dimensional manner because all the horizontal directions of the floor are collectively divided into one area. The fixed position absence information is configured by a range of the presence state indicated by “present” or the absence state indicated by “absence” at each position. In this case, the panel of the wings 23 is controlled so that the blower condition setting means 14 swings to the range a detected as being absent as shown in FIG.
FIG. 14 is a conceptual diagram showing an example of the fixed position absence information different from the fixed position absent information of FIG. 13 in one dimension. The fixed position absence information is configured by a range other than the presence state indicated by “present”, the absence state indicated by “absent”, and the fixed position indicated by black. In this case, the blower condition setting unit 14 swings to the range b detected as the absence state shown in FIG. 13 or the range c other than the fixed position adjacent to the absence state range so that the indoor blower blows. The panel of wings 23 is controlled.

As described above, according to the air-conditioning / air-blowing control device according to the third embodiment, a fixed position where a person is located is set, and the indoor fan is blown by detecting that the presence / absence state of the person at the fixed position is changed to absent. By setting at least one of the blowing intensity and the blowing angle to be performed, it is possible to prevent the air that has been adjusted as in the past from being continuously sent to a place where a person is not steadily wasted and wasted. Thereby, a comfortable environment can be provided by blowing the air-conditioned wind to the position where the person exists again. In addition, since the air blowing direction is directed to the position where the presence / absence state has changed to the absence state, it is possible to blow air toward the floor compared to the direction horizontal to the ceiling to avoid air blowing to the person, Heating efficiency rises compared with the case where it continues blowing in the direction.
Moreover, since it was set as the structure which swings in the area | region including absence, the circulation of the whole room | chamber 30 becomes good and heating efficiency rises.

In addition, in the above-described embodiment, when two or more positions where the presence / absence state of the fixed position detected when a person is present are detected to be absent are detected, the blowing condition setting unit can blow air to two places. Set conditions.
Furthermore, the temperature of the room 30 is measured by installing a temperature sensor in which the position information is known in the room 30, setting the angle of the panel of the wings 23 in the air blowing direction for each time, and feeding back and evaluating the information from the temperature sensor. It can be made uniform in position. FIG. 15A shows an operating time in which the angle of the panel of the wings 23 is controlled every predetermined time by swinging every angle range of 0 to 20 °, 20 to 40 °, and 60 to 80 ° excluding the range of the existing state. And a graph in which the operation time is shifted. By changing the operating time for each swing angle in this way, temperature information from the temperature sensor in the room 30 as shown in FIG. 15B is measured. By performing the evaluation based on this result, the setting angle of the wings 23 can be changed, and the temperature of the entire room 30 can be made closer to uniform, giving comfort to the occupants.

  In addition, all of the air-conditioning / air-blowing control device 10 of the above embodiment can be realized by the hardware configuration shown in FIG. FIG. 16 is a hardware configuration diagram in the case where the air-conditioning / air-blowing control device 10 according to the first embodiment is realized by hardware. The fixed position setting means 11, presence / absence detection means 12, absence detection means 13, and blowing condition setting means 14 are all realized by the processor 41. Further, the memory 42 is used to store information in the fixed position setting means 11, presence / absence detection means 12, absence detection means 13, and air blowing condition setting means 14. The communication interface 16 is realized by the communication interface 43.

In addition, when a person returns to a fixed position, it is detected by a presence / absence detection unit, and the air blowing direction is controlled to be an air flow along the ceiling.
Although the base information is information on the temperature distribution in the room 30 where no one is present, it may be measured when there is a person in the room 30.
Moreover, although the said embodiment demonstrated the case where it heats, this invention is applicable also in the case of the air_conditioning | cooling using a heat exchanger. Furthermore, the present invention can be applied to an air conditioner that performs air cleaning.
