  Next, a control procedure in the child priority mode of the air conditioner 1 according to the first embodiment will be described. FIG. 7 is a flowchart illustrating a procedure when the air conditioner 1 according to the first embodiment of the present invention performs control in the child priority mode.

  While the air conditioner 1 is operating in the normal mode, the user selects the child priority mode using the remote control operation unit 43 of the remote controller 4 and inputs the reference height information. When the child priority mode is selected and the reference height information is input, the remote control operation unit 43 transmits the child priority mode selection information and the reference height information indicating that the child priority mode is selected to the remote control unit 41. Upon receiving the child priority mode selection information and the reference height information, the remote control unit 41 sends the child priority mode and the reference height information to the air conditioning control unit 21 via the remote control communication unit 44 and the indoor unit communication unit 25 of the indoor unit 2.

In addition, when receiving the child priority mode selection information, the activity detection unit 23 operates until receiving the child priority mode release information.

  Next, in step S20, the human body detection unit 22 determines whether there is a person in the room. The human body detection unit 22 generates indoor temperature distribution information based on the infrared detection result detected by the infrared sensor 22a. The human body detection unit 22 determines whether or not there is a person in the room by comparing the shape of the high-temperature part that is higher than the other regions in the generated temperature distribution in the room with a plurality of reference samples. . The reference sample has a shape of a high-temperature portion that serves as a reference for determining that there is a person in the room. The reference sample is stored in the human body detection unit 22 in advance. The reference sample may have an arbitrary deformation width in a specific shape serving as a reference.

  Here, the high temperature part that is higher than the other regions in the information on the temperature distribution in the room is a part to be determined for determining that there is a person in the room. This high temperature portion is a portion where the temperature distribution in the room is higher than the predetermined temperature range by a predetermined temperature range or higher than the other regions, or a portion where the temperature is higher than the predetermined temperature. The predetermined temperature range and the predetermined temperature are stored in the human body detection unit 22 in advance. Further, the predetermined temperature range and the predetermined temperature can be appropriately changed by the remote controller 4.

  The human body detection unit 22 determines that there is a person in the room, that is, a person has been detected when the shape of the high temperature portion in the temperature distribution in the room satisfies the condition of the reference sample. The human body detection unit 22 determines that there is no person in the room when the shape of the high temperature portion in the temperature distribution in the room does not satisfy the conditions of the reference sample. In addition, there is no restriction | limiting in particular about the method of determining whether a person exists in a room, It is not limited to said method.

  If it is determined that there is no person in the room, that is, if No in step S20, the human body detection unit 22 repeats the process in step S20.

  If it is determined that there is a person in the room, that is, if Yes in step S20, the human body detection unit 22 determines whether there is a child in the room in step S30. The human body detection unit 22 compares the reference height information, which is a criterion condition for determining the presence / absence of a child in the room, with the detected height information, which is information on the height of a person detected in the room, to thereby detect the child in the room. The presence or absence of is determined. That is, the human body detection unit 22 determines whether or not the detected height information is equal to or less than the reference height information.

  When the height indicated by the detected height information of the person detected in the room is equal to or less than the height specified by the reference height information, the human body detection unit 22 determines that the person detected in the room is a child. On the other hand, when the height indicated by the detected height information of the person detected in the room is larger than the height specified by the reference height information, the human body detection unit 22 determines that the person detected in the room is not a child. As an example, when the height specified in the reference height information is 100 cm, the human body detection unit 22 determines that a person whose detected height is 100 cm or less in the room is a child.

  If it is determined that there are no children in the room, that is, if No in step S30, the human body detection unit 22 returns to step S20.

Information and indoor temperature distribution information are periodically transmitted to the activity detector 23.

  Upon receiving the child occupancy information and the room temperature distribution information, the activity detection unit 23 determines the activity state of the child in the room based on the child occupancy information and the room temperature distribution information.

  In step S40, the activity detection unit 23 determines whether or not a child in the room is standing and moving around. Whether or not the child in the room is standing and moving around is determined by whether or not the high temperature portion of the temperature distribution in the room is moving a distance greater than or equal to a predetermined reference movement distance within a predetermined reference time. The predetermined reference time is a time used as a reference for the activity detection unit 23 to determine whether or not a child in the room is standing and moving around, and is stored in the activity detection unit 23 in advance. The predetermined reference movement distance is a movement distance serving as a reference for determining whether or not a child in the room is standing and moving around, and is stored in the activity detection unit 23 in advance. Note that the information on the predetermined reference time and the predetermined reference movement distance may be stored in another storage unit included in the indoor unit 2.

  The activity detection unit 23 determines that the child in the room is standing and moving around when the moving distance of the high temperature portion in the indoor temperature distribution is equal to or greater than the reference moving distance within the reference time. In addition, the activity detection unit 23 determines that the child in the room is not standing and moving when the moving distance of the high temperature portion in the indoor temperature distribution is less than the reference moving distance within the reference time. . In addition, there is no restriction | limiting in particular about the method of detecting whether the child who is indoors is standing and moving around, It is not limited to said method.

  When it is determined that the child in the room is standing and moving around, that is, in the case of Yes in step S40, the activity detecting unit 23 indicates that the child in the room is standing and moving around. The activity state information is transmitted to the air conditioning control unit 21.

  When the air conditioning control unit 21 receives the first activity state information, in step S90, the air conditioning control unit 21 performs the first operation control for adjusting the condition of the cooling operation corresponding to the first activity state information. In the first operation control, the air conditioning control unit 21 blows conditioned air throughout the room, detects the body temperature of the child standing and moving indoors, and determines the body temperature of the child standing and moving indoors. Adjust the set temperature for cooling operation to a suitable temperature. That is, the air-conditioning control unit 21 adjusts the rotational speed of the compressor 72 based on the child's activity state and the child's body temperature, and performs control to adjust the temperature of the conditioned air blown out from the indoor unit 2 into the room. Do. Thereby, the temperature environment around the moving child can be controlled to be comfortable for the child.

  The air conditioning control unit 21 detects the temperature of the child by acquiring information on the temperature distribution in the room from the human body detection unit 22. Information on the temperature of the conditioned air suitable for the body temperature of a child standing and moving indoors is stored in the air conditioning control unit 21 in advance. Moreover, the information of the temperature of the conditioned air suitable for the body temperature of the child standing and moving around in the room may be stored in another storage unit in the indoor unit 2. After step S90 ends, step S70 described later is performed.

  When it is determined that the child in the room is not standing and moving, that is, in the case of No in step S40, in step S50, the activity detection unit 23 determines whether or not the child in the room is sitting. judge. The activity detector 23 determines whether or not the child in the room is sitting by comparing the shape and size of the high-temperature portion corresponding to the child in the temperature distribution in the room with a plurality of reference samples. Thereby, it can be excluded that the state where the adult is sitting is the state where the child sitting in the room is sitting. The reference sample is stored in the human body detection unit 22 in advance. The shape and size of the reference sample may have an arbitrary deformation width in a specific shape serving as a reference.

  The human body detection unit 22 determines that the child in the room is sitting when the shape and size of the high-temperature part corresponding to the child in the indoor temperature distribution satisfy the shape and size conditions of the reference sample. To do. In addition, the human body detection unit 22 is configured such that when the shape and size of the high-temperature portion corresponding to the child in the indoor temperature distribution does not satisfy the condition of the shape and size of the reference sample, Judge that there is no. In addition, there is no restriction | limiting in particular about the method of detecting whether the child who is indoors is a sitting state, It is not limited to said method.

  If it is determined that the child who is indoors is sitting, that is, if Yes in step S50, the activity detection unit 23 is the second activity state information indicating that the child who is indoors is sitting. Is transmitted to the air conditioning control unit 21.

  When the air conditioning control unit 21 receives the second activity state information, in step S100, the air conditioning control unit 21 performs the second operation control for adjusting the condition of the cooling operation corresponding to the second activity state information. In the second operation control, the air conditioning control unit 21 detects the body temperature of the child and adjusts the set temperature for the cooling operation to a temperature suitable for the body temperature of the child sitting. That is, the air-conditioning control unit 21 adjusts the rotational speed of the compressor 72 based on the child's activity state and the child's body temperature, and performs control to adjust the temperature of the conditioned air blown out from the indoor unit 2 into the room. Do.

  In the second operation control, the air conditioning control unit 21 determines whether to blow conditioned air from the indoor unit 2 toward the child sitting or to avoid blowing conditioned air toward the child sitting. Judgment is made based on the body temperature of the child, and the presence or absence of conditioned air blowing toward the child sitting is controlled. The air conditioning control unit 21 adjusts the direction of the wind direction plate 54 based on the activity state of the child and the body temperature of the child when the conditioned air is blown, and the wind direction of the conditioned air blown into the room from the indoor unit 2. Control to adjust.

  In addition, when the conditioned air is blown toward the child sitting, the air conditioning control unit 21 performs control to determine and adjust the air volume of the conditioned air to be blown toward the child based on the body temperature of the child. . That is, the air conditioning control unit 21 adjusts the rotation speed of the indoor fan 62 based on the child's activity state and the child's body temperature, and performs control to adjust the air volume of the conditioned air blown out from the indoor unit 2 into the room. Do.

  Thereby, it is possible to prevent the child from losing physical condition due to the airflow of the conditioned air hitting the child in the room too much or the temperature of the conditioned air being too low for the child. In addition, it is also possible to perform control to adjust at least one of the presence / absence of conditioned air blowing toward the child and the amount of conditioned air blowing toward the child to a condition suitable for the child's body temperature.

  The temperature of the conditioned air suitable for the body temperature of the sitting child, the presence / absence of conditioned air blowing toward the sitting child, and the volume of the conditioned air blown toward the child are stored in the air conditioning control unit 21 in advance. It is determined based on the determination criteria. Since the air conditioning control unit 21 includes a table storing such determination criteria, it is possible to finely control the air conditioning conditions raised for the child's body temperature. The table may be stored in another storage unit in the indoor unit 2. After step S100 is completed, step S70 described later is performed.

  If it is determined that the child in the room is not in a sitting state, that is, if No in step S50, the activity detection unit 23 determines in step S60 whether the child in the room is sleeping. To do. The activity detection unit 23 determines whether or not the child in the room is sleeping by comparing the shape and size of the high temperature portion corresponding to the child in the temperature distribution with a plurality of reference samples. The reference sample is stored in the human body detection unit 22 in advance. The shape and size of the reference sample may have an arbitrary deformation width in a specific shape serving as a reference.

  The human body detection unit 22 determines that the child in the room is sleeping when the shape and size of the high-temperature portion corresponding to the child in the temperature distribution in the room satisfy the shape and size conditions of the reference sample. To do. In addition, the human body detection unit 22 is configured such that when the shape and size of the high-temperature portion corresponding to the child in the indoor temperature distribution does not satisfy the conditions of the shape and size of the reference sample, the child in the room is in a sleeping state. Judge that there is no. In addition, there is no restriction | limiting in particular about the method of detecting whether the child who is indoors is a sleeping state, It is not limited to said method.

  When it is determined that the child in the room is sleeping, that is, in the case of Yes in step S60, the activity detection unit 23 indicates the third activity state information indicating that the child in the room is sleeping. Is transmitted to the air conditioning control unit 21.

  When the air conditioning control unit 21 receives the third activity state information, in step S110, the air conditioning control unit 21 performs the third operation control for adjusting the condition of the cooling operation corresponding to the third activity state information. The third operation control is the same control as the second operation control. After step S110 ends, step S70 described later is performed.

  If it is determined that the child in the room is not sleeping, that is, if No in step S60, the air conditioning control unit 21 has received whether or not the child priority mode release information has been received from the remote controller 4 in step S70. Determine whether.

  When the cancellation information of the child priority mode is received, that is, in step S70, if Yes, the air conditioning control unit 21 transmits the cancellation information of the child priority mode to the human body detection unit 22 and the activity detection unit 23 in step S80. Release the control of the cooling operation in the child priority mode. When the control of the cooling operation is canceled in the child priority mode, the air conditioning control unit 21 newly operates in the operation mode before the transition to the child priority mode, the default operation mode when the child priority mode is canceled, or the remote controller 4. Control the cooling operation in the selected operation mode. Moreover, the human body detection part 22 will cancel | release reference | standard height information, if the cancellation information of child priority mode is received.

  If the cancellation information of the child priority mode has not been received, that is, if No in step S70, the process returns to step S40. Since children's activity status changes frequently, it is necessary to reconfirm the children's activity status regularly and change the control of the cooling operation, so that the cooling operation can be more precisely tailored to the indoor child's activity status. It can be controlled, and it can avoid the child's physical condition from being cooled.

  In addition, unless the control of the cooling operation in the child priority mode is canceled, when the human body detection unit 22 detects the presence of a new child, the child priority after step S40 is also applied to the newly detected child. Control of the cooling operation in the mode is performed.

  In the above description, the air conditioning control unit 21 and the activity detection unit 23 are provided in the indoor unit 2. However, the air conditioning control unit 21 and the activity detection unit 23 may be provided in the outdoor unit 3.

  As described above, the air conditioner 1 controls the cooling operation under conditions suitable for the child's activity state based on the child's activity state information. That is, the air conditioner 1 determines the temperature of the conditioned air in the cooling operation based on the information on the presence or absence of the child in the room, the information on the activity state of the child in the room, and the information on the body temperature of the child in the room. Control to adjust the conditions suitable for the body temperature. Furthermore, the air conditioner 1 performs control to adjust at least one of the presence / absence of conditioned air blowing toward the child and the amount of conditioned air blowing toward the child to a condition suitable for the child's body temperature. be able to.

  Children's body temperature and temperature fluctuations vary depending on their activity. That is, the body temperature and the variation in body temperature are different between a child standing and moving, a child sitting, and a child sleeping. Although it varies depending on the child, the temperature of a child standing and moving around is the highest, and the temperature of a sleeping child tends to be the lowest. Therefore, by controlling the cooling operation individually based on the information on the child's activity state according to the child's activity state, a comfortable space for the child can be created under conditions suitable for the child's activity state.

  And since the air conditioner 1 can adjust the setting conditions of air_conditionaing | cooling operation based on the body temperature of the child who exists indoors, it can perform comfortable air-conditioning control for the child from which a body temperature differs from an adult. Therefore, the air conditioner 1 has a low ambient temperature because the air flow of the conditioned air hits the child too much, or even if the air flow of the conditioned air does not directly hit the child, the temperature of the conditioned air is too low for the child. Can be prevented from losing health.

  The air conditioner 1 is an air conditioner that is a facility where many children gather, such as a kindergarten, a nursery school, and a hospital where the waiting time is long or the user has to stay indoors for a long time without playing outside. Even in situations where people stay indoors, driving in the child priority mode can prevent children from losing their physical condition due to cooling.

  In the above description, the case where the air conditioner 1 performs the cooling operation has been described. However, even when the air conditioner 1 performs the heating operation or the air blowing operation, the child priority mode is performed as in the case of the above-described cooling operation. Driving is possible. Also in this case, as in the case of the cooling operation, it is possible to prevent the child from losing physical condition due to excessive hitting of the airflow from the indoor unit 2 or due to the temperature of the airflow from the indoor unit 2. .

  In addition, in a kindergarten, nursery school, or hospital where many children gather, when the human body detection unit 22 detects a group of children in close proximity to each other, individual children are individually identified. It may be difficult to set the air conditioning operation. In this case, the air-conditioning control unit 21 adjusts the setting condition of the cooling operation according to the body temperature of the child whose body temperature is low in the group, and sets the cooling operation according to the average body temperature of the plurality of children included in the group. It is also possible to perform control such as adjusting the conditions.

  Therefore, the air conditioner 1 according to the first embodiment can perform a child-friendly air conditioning operation in consideration of the physical condition of the child in accordance with the activity state of the indoor child, that is, in accordance with the body temperature of the indoor child. , Has the effect.

Embodiment 2. FIG.
In the first embodiment described above, the case where the reference height information, which is the determination criterion condition for determining the presence / absence of a child in a room, is one fixed value has been described. A range of heights may be used. The height range of the child is a height range in which an upper limit value and a lower limit value determined by the human body detection unit 22 as a child are set.

  FIG. 8 is a flowchart illustrating a procedure in the case where the air conditioner 1 according to Embodiment 2 of the present invention performs control in the child priority mode. The process shown in FIG. 8 is an example of the cooling operation process in the child priority mode that is repeatedly executed in a preset cycle when the child priority mode is selected by the remote controller 4. In FIG. 8, the same steps as those in the flowchart shown in FIG.

  While the air conditioner 1 is operating in the normal mode, the user selects the child priority mode in the remote control operation unit 43 of the remote controller 4 and inputs the range of the child's height as the reference height information. When the child priority mode is selected and the reference height information is input, the remote control operation unit 43 transmits the child priority mode selection information and the reference height information indicating that the child priority mode is selected to the remote control unit 41. When receiving the child priority mode selection information and the reference height information, the remote controller 41 receives the child priority mode selection information and the reference height information via the remote control communication unit 44 and the indoor unit communication unit 25 of the indoor unit 2. To 21.

  When the air conditioning control unit 21 receives the child priority mode selection information and the reference height information in step S210, the child priority mode selection information and the reference height information are sent to the human body detection unit 22, and the child priority mode selection information is sent to the activity detection unit 23. Send and start controlling the cooling operation in the child priority mode.

  Next, in step S20, the human body detection unit 22 determines whether or not there is a person in the room in the same manner as in the first embodiment.

  If it is determined that there is no person in the room, that is, if No in step S20, the human body detection unit 22 repeats the process in step S20.

  If it is determined that there is a person in the room, that is, if Yes in step S20, the human body detection unit 22 determines whether there is a child in the room in step S220. The human body detection unit 22 compares the reference height information, which is a criterion condition for determining the presence / absence of a child in the room, with the detected height information, which is information on the height of a person detected in the room, to thereby detect the child in the room. The presence or absence of is determined. The reference height information here is the range of the child's height. The human body detection unit 22 determines whether or not the detected height information is within the height range specified by the reference height information.

  The human body detection unit 22 determines that a person detected in the room is a child when the detected height information of the person detected in the room is within the height range specified by the reference height information. On the other hand, the human body detection unit 22 determines that the person detected indoors is not a child when the detected height information of the person detected indoors is outside the height range specified by the reference height information. As an example, when the height range specified by the reference height information is 50 cm to 120 cm, the human body detection unit 22 detects a person whose detected height of the person detected in the room is within the range of 50 cm to 120 cm as a child. It is determined that By using the range of the height of the child as the reference height information, it is possible to reduce erroneous determination when the human body detection unit 22 determines whether there is a child in the room. An example of erroneous determination when the human body detection unit 22 determines whether or not there is a child in the room is to determine that the animal is a child.

  Thereafter, Steps S40 to S110 are performed in the same manner as in the first embodiment.

  In the second embodiment, the air conditioner 1 determines whether the child is a child using the reference height information, and thus has the same effect as in the first embodiment.

  Moreover, in this Embodiment 2, since the range of a child's height is used as reference | standard height information in the air conditioner 1, the human body detection part 22 reduces the misjudgment at the time of determining whether there is a child in a room. Can do. By reducing the erroneous determination of the child in the human body detection unit 22, the air conditioning operation in accordance with the body temperature of the child in the room can be performed with higher accuracy.

  In particular, in places such as kindergartens, nursery schools, and hospitals where many children gather, reducing the number of misidentifications of children in the human body detection unit 22 enables more comfortable air conditioning operation for more children. .

  Furthermore, the range of the height of the child set as the reference height information can be changed according to the growth of the child. For example, every time a kindergarten class or a nursery school class changes, the height of the child with the lowest height to the height of the child with the highest height is set as the upper and lower limits of the height range. Thereby, the human body detection part 22 can detect without misrecognizing the child of all the classes.

Embodiment 3 FIG.
In Embodiment 1 and Embodiment 2 described above, a case where the user selects the child priority mode from the remote controller 4 and sets the reference height information, the operation control of the air conditioner 1 is switched to the child priority mode is shown. It was. In Embodiment 3, an automatic child priority mode that can automatically switch to the child priority mode will be described. In the automatic child priority mode, when there is a child in the room when the automatic child priority mode is set, the air conditioner 1 performs the same control as the automatic child priority mode described above. Hereinafter, a case where there is no child in the room when the automatic child priority mode is set will be described.

  FIG. 9 is a flowchart for explaining a control procedure in the automatic child priority mode of the air conditioner 1 according to Embodiment 3 of the present invention. In FIG. 9, the same step numbers are assigned to the same processes as those in the flowchart shown in FIG.

  While the air conditioner 1 is operating in the normal mode, the user selects the automatic child priority mode using the remote control operation unit 43 of the remote controller 4 and inputs the range of the child's height as the reference height information. When the automatic child priority mode is selected and the reference height information is input, the remote control operation unit 43 transmits the automatic child priority mode selection information and the reference height information to the effect that the automatic child priority mode is selected to the remote control unit 41. To do. When receiving the automatic child priority mode selection information and the reference height information, the remote control unit 41 air-conditions the automatic child priority mode selection information and the reference height information via the remote control communication unit 44 and the indoor unit communication unit 25 of the indoor unit 2. It transmits to the control part 21.

  When the air conditioning control unit 21 receives the automatic child priority mode selection information and the reference height information in step S310, the automatic child priority mode selection information and the reference height information are detected in the human body detection unit 22 and the automatic child priority mode selection information is detected in the activity. It transmits to the part 23. Here, when receiving the automatic child priority mode selection information, the human body detection unit 22 detects the child in the room until receiving the cancellation information of the automatic child priority mode. In addition, when receiving the automatic child priority mode selection information, the activity detection unit 23 operates until receiving the cancellation information of the automatic child priority mode.

  Next, the human body detection unit 22 periodically detects a person at the entrance of the room, and the human body detection unit 22 determines whether or not a person has entered the room in step S320.

  If it is determined that no person has entered the room, that is, if No in step S320, the human body detection unit 22 repeats the process of step S320.

  If it is determined that a person has entered the room, that is, if Yes in step S320, the human body detection unit 22 determines whether a child has entered the room in step S330. The human body detection unit 22 detects the entrance of the child in the room by comparing the reference height information with the detected height information that is the height information of the person who has detected that the person has entered the room. The reference height information here is the range of the child's height. The human body detection unit 22 determines whether or not the detected height information is within the height range specified by the reference height information.

  The human body detection unit 22 determines that the person detected as having entered the room is a child when the detected height information of the person detected to have entered the room is within the height range specified by the reference height information, On the other hand, the human body detection unit 22 determines that the child has entered the room. If the detected height information of the person detected to have entered the room is outside the height range specified by the reference height information, It is determined that the person detected to have entered the room is not a child, and it is determined that no child has entered the room.

  If it is determined that no child has entered the room, that is, if No in step S330, the human body detection unit 22 returns to step S320.

  If it is determined that a child has entered the room, that is, if Yes in step S330, the air conditioning control unit 21 automatically switches to the child priority mode, and from step S40 to step S60, as in the first embodiment, And step S90 to step S110 are implemented.

  Here, when it is determined that the child in the room is not in a sleeping state, that is, in the case of No in step S60, the air conditioning control unit 21 receives the release information of the automatic child priority mode from the remote controller 4 in step S340. It is determined whether or not it has been received.

  If the automatic child priority mode cancellation information is received, that is, if Yes in step S340, the air conditioning control unit 21 sends the automatic child priority mode cancellation information to the human body detection unit 22 and the activity detection unit 23 in step S350. Send and release control of cooling operation in automatic child priority mode. When the control of the cooling operation is canceled in the automatic child priority mode, the air conditioning control unit 21 is the operation mode before the transition to the automatic child priority mode, the default operation mode when the automatic child priority mode is canceled, or the remote controller 4. The cooling operation is controlled in the newly selected operation mode.

  If the cancellation information of the automatic child priority mode has not been received, that is, if No in step S340, the process returns to step S320.

  In addition, when the human body detection unit 22 determines that a new child has entered the room, the cooling operation control in the child priority mode after step S40 is performed for the child that is determined to have newly entered the room. .

  The air conditioning control in the automatic child priority mode in the third embodiment has the same effect as that in the first embodiment because the air conditioner 1 determines whether or not the child is a child using the reference height information.

  Further, the air conditioning control in the automatic child priority mode has the same effect as that of the second embodiment because the air conditioner 1 uses the range of the child's height as the reference height information.

  Further, in the air conditioning control in the automatic child priority mode, when the human body detection unit 22 detects that a child has entered the room, the mode is automatically switched to the child priority mode. For this reason, in this Embodiment 3, every time a child enters and leaves the room and a child in the room is changed, the newly entered child is matched to the activity state of the child in the room, that is, the child in the room. A child-friendly air-conditioning operation that takes into account the physical condition of the child is possible according to the body temperature of the child.

  The air conditioning control in the automatic child priority mode is particularly effective in places where children enter and exit frequently such as kindergartens, nurseries, and hospital waiting rooms. In addition, air conditioning control in the automatic child priority mode automatically and smoothly switches to the child priority mode even when the user forgets to set the child priority mode. .

  In the above description, the case where the range of the child's height is used as the reference height information has been described, but one fixed value may be used for the reference height information as in the first embodiment.

  In the above description, the case where the automatic child priority mode is set when the air conditioning control unit 21 receives the automatic child priority mode selection information and the reference height information has been described. However, the automatic child priority mode selection information is used. The form may not be used. In this case, when the reference height information is stored in the human body detection unit 22 via the air conditioning control unit 21 or in a state where the air conditioning control unit 21 does not receive the child priority mode selection information, the air conditioning control unit 21 When the child priority mode is set and the human body detection unit 22 detects a child, the air conditioning control unit 21 switches to the child priority mode.
