The user terminal device is a liquid crystal terminal such as a smartphone, for example, and supplies an operation change command (operation start operation, operation stop operation, set temperature of the room temperature, etc.) to the air conditioner 1 via the network. be able to.

In the cooling operation and the dehumidifying operation, as indicated by the solid arrows in the figure, the refrigerant discharged from the compressor 10 flows in order from the four-way valve 11 to the outdoor heat exchanger 12, the expansion valve 13, and the indoor heat exchanger 14.
A cooling cycle or a dehumidification cycle is formed in which the refrigerant that has passed through the indoor heat exchanger 14 returns to the compressor 10 through the four-way valve 11. That is, the outdoor heat exchanger 12 functions as a condenser and the indoor heat exchanger 14 functions as an evaporator.

On the other hand, in the heating operation, as the four-way valve 11 is switched,
The refrigerant discharged from the compressor 10 sequentially flows from the four-way valve 11 to the indoor heat exchanger 14, the expansion valve 13, and the outdoor heat exchanger 12, and the refrigerant that has passed through the outdoor heat exchanger 12 passes through the four-way valve 11 and becomes a compressor. 10
A heating cycle is formed that returns to That is, the indoor heat exchanger 14 functions as a condenser, and the outdoor heat exchanger 12 functions as an evaporator.

An indoor fan 16 that faces the indoor heat exchanger 14 is disposed in the indoor unit 2. Indoor unit 2
The upper and lower flaps 17 that change the blowing direction in the vertical direction are arranged at the outlet. As shown in FIG. 1, an indoor temperature sensor (indoor temperature detecting means) 21 for detecting the indoor temperature and an indoor humidity sensor (indoor humidity detecting means) 22 for detecting the indoor humidity are attached to the indoor unit 2. Moreover, the indoor unit 2 has a human detection sensor (human detection means) 25 that detects a person in the room (air-conditioned space).

As shown in FIG. 2, the control unit 50 of the air conditioner 1 includes a compressor 10, a four-way valve 11, an expansion valve 13, a motor 16 a that drives the indoor fan 16, and a motor 17 a that drives the upper and lower flaps 17. The indoor temperature sensor 21, the indoor humidity sensor 22, the human detection sensor 25, and the controller 28 attached to the air conditioner 1 are connected. Moreover, the control part 5 of the air conditioner 1
0 changes the operation of the air conditioner 1 based on the operation change command supplied from the terminal device 30 of the user. The user terminal device 30 is a liquid crystal terminal such as a smartphone, for example,
An operation change command (operation start operation, operation stop operation, indoor temperature set temperature, etc.) can be supplied to the air conditioner 1 via the network. Therefore, the control unit 50 controls the commands from the controller 28 and the user terminal device 30 (operation start operation, operation stop operation, set temperature of the room temperature, etc.), the room temperature detected by the room temperature sensor 21, and the room humidity. Sensor 22
The operation of the air conditioner 1 is controlled based on the indoor humidity detected at 1. As described above, the air conditioner 1 of the present embodiment not only changes the operation state based on the commands from the controller 28 (operation start operation, operation stop operation, indoor temperature set temperature, etc.), Terminal device 3
Operation change command supplied from 0 (operation start operation, operation stop operation, indoor temperature set temperature, etc.)
The operating state is changed based on the above.

Here, the controller 28 is provided with a display unit, a temperature adjustment unit, an operation start button, and a stop button. The controller 28 includes an operation selection unit, an air volume selection unit,
And a wind direction selector.

An operation display unit, a set temperature display unit, and an operation mode display unit are displayed on the display unit. The operation selected by the operation selection unit (automatic, cooling, heating, dehumidification, and blowing operation) is displayed on the operation display unit. Moreover, the temperature changed by operating the temperature adjustment part is displayed on the set temperature display part.

The temperature adjustment unit changes the set temperature. The temperature adjustment unit can be operated to increase the set temperature, or the temperature adjustment unit can be operated to decrease the set temperature. The operation selected by the operation selection unit is started by pressing the operation start button, and the operation is stopped by pressing the stop button during the operation.

The operation selection unit of the controller 28 can be switched between automatic, cooling, heating, dehumidification and ventilation. The air volume selection unit can select the air volume by switching between automatic, fine (small amount), weak (small amount), and strong (large amount). The wind direction can be selected from the automatic, upward (upward), middle (horizontal), and downward (downward) directions by the wind direction selector.

The controller 28 is provided with a mode switching unit. By the mode switching unit, the high temperature prevention mode of the air conditioner 1 can be switched to any one of the forced operation mode, the notification mode, and the off mode. In the air conditioner 1 of the present embodiment, the absence notification mode is set when the high temperature prevention mode is switched off.

Therefore, in the air conditioner 1 of the present embodiment, any one of the forced operation mode, the notification mode, and the absence notification mode (high temperature prevention mode off) is set by the mode switching unit. Therefore, in the air conditioner 1, the operation in the forced operation mode, the operation in the notification mode, and the operation in the absence notification mode are not performed simultaneously.

In the forced operation mode, when the room is in a high temperature state or a high humidity state, the forced operation is automatically started based on the room temperature and the room humidity. Therefore, when the operation mode is switched to the forced operation mode, the forced operation is automatically started even when the user does not perform the operation start operation by the controller 28 or the terminal device 30 when the room is in a high temperature state or a high humidity state. As a result, the room temperature and the room humidity decrease.

In the notification mode, when the room is in a high temperature state or a high humidity state, a notification that prompts the start of operation is automatically performed based on the room temperature and the room humidity. As a notification to prompt the start of operation, for example, the content “The room is hot. Please start cooling operation” is notified by voice from the indoor unit 2 or displayed on the display unit of the indoor unit 2 Is done.

In the air conditioner 1 of the present embodiment, when the forced operation is automatically performed in the forced operation mode, the air-conditioning space information indicating that the room is in a high temperature state or a high humidity state is the terminal device 3 of the user.
0 is supplied. As the air-conditioning space information in this case, for example, the content “The room is hot. Cooling operation has been started” is supplied to the terminal device 30 of the user and displayed on the display screen of the terminal device 30. The In addition, when a notification for prompting the start of operation is automatically performed in the notification mode, air-conditioned space information indicating that the room is in a high temperature state or a high humidity state is supplied to the user terminal device 30. As the air-conditioned space information in this case, for example, the content “The room is hot. Start cooling operation” is supplied to the terminal device 30 of the user and displayed on the display screen of the terminal device 30. Is done. In the present embodiment, whether the room is in a high temperature state or a high humidity state is determined every predetermined time, and if the room is in a high temperature state or a high humidity state, the air-conditioned space information is predetermined. It may be supplied to the terminal device 30 of the user every hour. In addition, after the notification that prompts the start of operation in the notification mode is automatically performed, when the operation of the air conditioner 1 is not started and the room is not in a high temperature state or a high humidity state, the room is in a high temperature state or a high humidity state. Release information indicating that it is no longer in the state is the terminal device 30 of the user
To be supplied. As release information in this case, for example, the content “The room temperature has dropped. It is not necessary to start the cooling operation.” Is supplied to the terminal device 30 of the user and displayed on the display screen of the terminal device 30. Is done.

In the absence notification mode, when there is no person in the room detected by the human detection sensor 25 and the operation of the air conditioner 1 is continued for a predetermined absence time, absence information indicating that there is no person in the room Is supplied to the terminal device 30 of the user. In the air conditioner 1 of this embodiment, when absence information is supplied to the user's terminal device 30 in the absence notification mode, for example, as the absence information, “the air conditioner is operated in a state where there is no person in the room” "Is supplied to the terminal device 30 of the user and displayed on the display screen of the terminal device 30.

When the mode is switched to the forced operation mode or the notification mode, the user cannot perform the operation stop operation of the air conditioner 1 by the controller 28 or the terminal device 30 of the user. Therefore, in the air conditioner 1, when the forced operation is started in the forced operation mode, the user cannot perform the operation stop operation of the air conditioner 1 by the controller 28 or the terminal device 30, and stops the forced operation. Therefore, it is necessary to switch the high temperature prevention mode off by operating the mode switching unit of the controller 28. In the air conditioner 1, the operation start operation of the air conditioner 1 can be performed by the controller 28 or the terminal device 30 in the notification mode, but after starting the operation of the air conditioner 1, the user
In addition, the operation stop operation of the air conditioner 1 cannot be performed by the terminal device 30, and in order to stop the operation, it is necessary to operate the mode switching unit of the controller 28 and switch the high temperature prevention mode off. Therefore, when the operation stop command is supplied from the terminal device 30 to the air conditioner 1 in the forced operation mode or the notification mode, the air conditioner 1 sends the terminal device 30.
On the other hand, information indicating that the operation stop operation cannot be performed by the terminal device 30 is supplied and displayed on the display screen of the terminal device 30. On the other hand, when the absence information is supplied to the user terminal device 30 in the absence notification mode, the user can perform the operation stop operation of the air conditioner 1 by the controller 28 or the terminal device 30.

In the air conditioner 1, when determining whether to start forced operation in the forced operation mode,
When determining whether to start the notification in the notification mode, a determination diagram for the room temperature and the room humidity is used. As shown in FIG. 3, the vertical axis indicates the room humidity (relative humidity).
The horizontal axis represents the room temperature.

  First, the forced operation mode will be described.

FIG. 3 is an example of a determination diagram in the forced operation mode. In this determination diagram, a high temperature zone, a monitoring zone, and a standby zone are set. The high temperature zone is an area where the room is in a high temperature state or a high humidity state and the room temperature or the room humidity needs to be lowered. The standby zone is a region far from the high temperature zone, and is a region where it is not necessary to reduce the room temperature or the room humidity. The monitoring zone is a region close to the high temperature zone, and is a region where the room temperature and the room humidity are easily changed to the high temperature zone.

In the determination diagram of FIG. 3, points A to F indicate the following indoor temperature and indoor humidity.
Point A: the room temperature is 27 degrees and the room humidity is 100% Point B: the room temperature is 27 degrees and the room humidity is y1 between 70 and 80% Point C: Point where room temperature is 33 degrees and room humidity is 30% Point D: Room temperature is 28 degrees Point of room humidity is 100% Point E: Room temperature is 28 degrees and room humidity Is the point y2 between 70 and 80%. · F point: The room temperature is 34 degrees and the room humidity is y3 between 30 and 40%.

A line 11 connecting points A, B, and C is a line between the standby zone and the monitoring zone, and a line 12 connecting points D, E, and F is the monitoring zone and the high temperature zone. The line between Therefore, as shown in the determination diagram of FIG. 4, the standby zone is the lower left region of the line l1, and the high temperature zone is the upper right region of the line l2 (the room temperature and the room humidity are the line l2
The monitoring zone is a region sandwiched between the high temperature zone and the standby zone (including the case where the room temperature and the room humidity are on the line l1).

Therefore, when the operation of the air conditioner 1 is stopped, when the operation mode is switched to the forced operation mode, the operation operation differs depending on whether the room temperature and the room humidity are in the high temperature zone, the monitoring zone, and the standby zone. Accordingly, the operation in each zone after switching to the forced operation mode will be described.

When the room temperature and the room humidity are in the high temperature zone, it is necessary to reduce the room temperature and the room humidity, so that the cooling operation (forced operation) is started. In the air conditioner 1, the cooling operation in the forced operation mode is a cooling operation at a set temperature of 28 ° C. Then, when the room temperature decreases by 1 degree or more from the set temperature (when the room temperature becomes 27 degrees or less), the cooling operation is in a thermo-off state. Here, the thermo-off state is a state where the compressor is stopped and the indoor fan 16 is driven. In the air conditioner 1, when the cooling operation is in the thermo-off state, the air volume is made lower than that in the cooling operation, and the upper and lower flaps 17 are arranged near the upper end of the movable range to change the blowing direction upward.

When the room temperature and the room humidity are in the monitoring zone, the room temperature and the room humidity are likely to change to the high temperature zone, and therefore it is necessary to detect the room temperature and the room humidity appropriately, so the air blowing operation is performed. The air blowing operation is an operation in which the compressor is stopped and the indoor fan 16 of the indoor unit is driven. In the air conditioner 1, the indoor temperature sensor 21 and the indoor humidity sensor 22 are
Since it is attached inside the indoor unit 2, when the upper and lower flaps 17 are closed and the heat is trapped inside the indoor unit when the operation is stopped, the indoor temperature and the indoor humidity may not be detected properly. Therefore, when the room temperature and the room humidity are in the monitoring zone, the air flow is started inside the indoor unit 2 by starting the air blowing operation, so that the room temperature and the room humidity can be properly detected. Here, in the air blowing operation when the room temperature and the room humidity are in the monitoring zone, the air volume is made lower than the air volume of the cooling operation, and the upper and lower flaps 17 are arranged near the upper end of the movable range so that the blowing direction is upward. change.

When the room temperature and the room humidity are in the standby zone, it is far from the high temperature zone, and it is not necessary to reduce the room temperature and the room humidity, so that the cooling operation and the air blowing operation are not performed.

Thus, in this embodiment, in the forced operation mode, the cooling operation (forced operation) is started when the room temperature and the room humidity are in the high temperature zone. Further, after the cooling operation is started, the cooling operation is stopped when the thermo-off state continues for a predetermined time.

  Next, the notification mode will be described.

An example of the determination diagram in the notification mode is the same as the example of the determination diagram in the forced operation mode shown in FIG. In this determination diagram, a high temperature zone, a monitoring zone, and a standby zone are set.

Therefore, when switching to the notification mode when the operation of the air conditioner 1 is stopped, the operation is different depending on whether the room temperature and the room humidity are in the high temperature zone, the monitoring zone, and the standby zone. Therefore, the driving operation in each zone after switching to the notification mode will be described.

When the room temperature and the room humidity are in the high temperature zone, it is necessary to reduce the room temperature and the room humidity.

When the room temperature and the room humidity are in the monitoring zone, the room temperature and the room humidity are likely to change to the high temperature zone, and therefore it is necessary to detect the room temperature and the room humidity appropriately, so the air blowing operation is performed. The air blowing operation is an operation in which the compressor is stopped and the indoor fan 16 of the indoor unit is driven. In the air conditioner 1, the indoor temperature sensor 21 and the indoor humidity sensor 22 are
Since it is attached inside the indoor unit 2, when the upper and lower flaps 17 are closed and the heat is trapped inside the indoor unit when the operation is stopped, the indoor temperature and the indoor humidity may not be detected properly. Therefore, when the room temperature and the room humidity are in the monitoring zone, the air flow is started inside the indoor unit 2 by starting the air blowing operation, so that the room temperature and the room humidity can be properly detected. Here, in the air blowing operation when the room temperature and the room humidity are in the monitoring zone, the air volume is made lower than the air volume of the cooling operation, and the upper and lower flaps 17 are arranged near the upper end of the movable range so that the blowing direction is upward. change.

When the room temperature and the room humidity are in the standby zone, it is far from the high temperature zone, and there is no need to reduce the room temperature and the room humidity.

As described above, in the present embodiment, in the notification mode, when the room temperature and the room humidity are in the high temperature zone, notification for starting the operation is started.

Next, control in the forced operation mode of the air conditioner 1 will be described with reference to FIG.

First, when the operation of the air conditioner 1 is stopped, the mode switching unit of the controller 30 switches to the forced operation mode (step S1). Here, a case will be described in which the room temperature and the room humidity when switched to the forced operation mode are in the standby zone (see FIG. 3).

In the forced operation mode, it is determined whether the room temperature detected by the room temperature sensor 21 and the room humidity detected by the room humidity sensor 22 are in the monitoring zone (step S2).
). When the room temperature and the room humidity change from the standby zone to the high temperature zone, it is considered that the room temperature and the room humidity change from the standby zone to the monitoring zone and then to the high temperature zone. Therefore, in step S2, based on whether the room temperature and the room humidity are in the monitoring zone, it is determined whether the room temperature and the room humidity are close to a high temperature zone where the cooling operation needs to be started.

When it is determined that the room temperature and the room humidity are in the monitoring zone (step S2: YES), the indoor fan 16 is driven to start the air blowing operation (step S3).
. When the room temperature and the room humidity are in the monitoring zone near the high temperature zone, the air flows into the indoor unit 2 by starting the air blowing operation, so that the room temperature and the room humidity can be properly detected.

On the other hand, when it is determined that the room temperature and the room humidity are not in the monitoring zone (step S2: NO), since the room temperature and the room humidity are in the standby zone, it is determined whether the room temperature and the room humidity are in the monitoring zone. (Step S2).

Then, after starting the air blowing operation in step S3, it is determined whether the room temperature detected by the room temperature sensor 21 and the room humidity detected by the room humidity sensor 22 are in the monitoring zone (step S4). When it is determined that the room temperature and the room humidity are in the monitoring zone (step S4: YES), the room temperature and the room humidity can be properly detected because the room temperature and the room humidity are in the monitoring zone near the high temperature zone. As described above, the air blowing operation is continued (step S3).

On the other hand, when it is determined that the room temperature and the room humidity are not in the monitoring zone (step S4: NO), it is considered that the room temperature and the room humidity have changed to the standby zone or the high temperature zone after starting the air blowing operation. . Therefore, it is determined whether the room temperature and the room humidity are in the standby zone (step S5). If it is determined that the room temperature and the room humidity are in the standby zone (step S4: YES), the air temperature operation is stopped because the room temperature and the room humidity have changed from the monitoring zone close to the high temperature zone to the standby zone. (Step S
6). Then, it transfers to step S2 and it is judged whether indoor temperature and indoor humidity exist in a monitoring zone. On the other hand, when it is determined that the room temperature and the room humidity are not in the standby zone (step S5: NO), the room temperature and the room humidity are in the high temperature zone, and it is necessary to reduce the room temperature and the room humidity. Cooling operation is started (step S7). At this time,
In the forced operation mode, the air-conditioning space information indicating that the room temperature and the room humidity are in the high temperature zone and the cooling operation is automatically started is supplied to the user terminal device 30 (step S8).
).

Thereafter, it is repeatedly determined whether an operation stop command is supplied from the terminal device 30 to the air conditioner 1 (step S9). When an operation stop command is supplied from the terminal device 30 to the air conditioner 1 (step S9: YES), information indicating that the operation stop operation cannot be performed by the terminal device 30 is supplied from the air conditioner 1 to the terminal device 30. (Step S10).

Next, control in the notification mode of the air conditioner 1 will be described with reference to FIG.

First, when the operation of the air conditioner 1 is stopped, the mode is switched to the notification mode by the mode switching unit of the controller 30 (step S101). Here, the case where the room temperature and the room humidity when the notification mode is switched is in the standby zone (see FIG. 3) will be described.

In the notification mode, it is determined whether the room temperature detected by the room temperature sensor 21 and the room humidity detected by the room humidity sensor 22 are in the monitoring zone (step S1).
02). When the room temperature and the room humidity change from the standby zone to the high temperature zone, it is considered that the room temperature and the room humidity change from the standby zone to the monitoring zone and then to the high temperature zone. Therefore, in step S2, based on whether the room temperature and the room humidity are in the monitoring zone, it is determined whether the room temperature and the room humidity are close to a high temperature zone where the cooling operation needs to be started.

When it is determined that the room temperature and the room humidity are in the monitoring zone (step S102: YES), the indoor fan 16 is driven to start the air blowing operation (step S).
103). If the room temperature and humidity are in the monitoring zone near the hot zone,
By starting the air blowing operation, air flows inside the indoor unit 2, so that the indoor temperature and the indoor humidity can be detected appropriately.

On the other hand, when it is determined that the room temperature and the room humidity are not in the monitoring zone (step S102: NO), since the room temperature and the room humidity are in the standby zone, it is determined whether the room temperature and the room humidity are in the monitoring zone. (Step S102).

Then, after the air blowing operation is started in step S3, it is determined whether the room temperature detected by the room temperature sensor 21 and the room humidity detected by the room humidity sensor 22 are in the monitoring zone (step S104). If it is determined that the room temperature and the room humidity are in the monitoring zone (step S104: YES), the room temperature and the room humidity can be properly detected because the room temperature and the room humidity are in the monitoring zone near the high temperature zone. As described above, the air blowing operation is continued (step S103).

On the other hand, when it is determined that the room temperature and the room humidity are not in the monitoring zone (step S104: NO), it is considered that the room temperature and the room humidity have changed to the standby zone or the high temperature zone after starting the air blowing operation. . Therefore, it is determined whether the room temperature and the room humidity are in the standby zone (step S105). If it is determined that the room temperature and the room humidity are in the standby zone (step S104: YES), the fan operation is stopped because the room temperature and the room humidity have changed from the monitoring zone close to the high temperature zone to the standby zone. (Step S106). Then, it transfers to step S2 and it is judged whether indoor temperature and indoor humidity exist in a monitoring zone. On the other hand, when it is determined that the room temperature and the room humidity are not in the standby zone (step S105: NO), the room temperature and the room humidity are in the high temperature zone, and it is necessary to reduce the room temperature and the room humidity. Notification for prompting the start of operation is started (step S107). At this time, in the notification mode, air-conditioning space information indicating that the room temperature and the room humidity are in the high temperature zone and the notification for prompting the start of operation is started is supplied to the user terminal device 30 (step S108). When the user who sees the air-conditioned space information determines that the operation of the air conditioner 1 is to be started, an operation start command is issued from the terminal device 30 to the air conditioner 1.
Therefore, it is repeatedly determined whether the operation start command is supplied from the terminal device 30 to the air conditioner 1 (step S109). And when the operation start command is supplied from the terminal device 30 to the air conditioner 1 (step S109: YES), the cooling operation of the air conditioner 1 is started (step S110). Thereafter, it is repeatedly determined whether an operation stop command has been supplied from the terminal device 30 to the air conditioner 1 (step S111). Then, when an operation stop command is supplied from the terminal device 30 to the air conditioner 1 (step S111: YES), information indicating that the operation stop operation cannot be performed by the terminal device 30 is supplied from the air conditioner 1 to the terminal device 30.

In the air conditioner 1 of the present embodiment, when the room is in a state where the room temperature or the room humidity needs to be reduced, the forced operation is automatically started in the forced operation mode, or the operation is started in the notification mode. When the prompting notification is automatically started, the air-conditioned space information (the room is in a state where the room temperature or the room humidity needs to be reduced) is supplied to the terminal device 30, so that the user can perform forced operation. While being able to know that it started automatically, the operation change command can be supplied from the terminal device 30 to the air conditioner 1 and the operation of the air conditioner 1 can be started.
Therefore, since it can suppress continuing for a long time in the state where indoor temperature and indoor humidity are high, it can prevent that a user becomes heat stroke etc.

Further, in the air conditioner 1 of the present embodiment, when the operation in the forced operation mode or the notification mode is performed, the change of the operation state based on the operation change command supplied from the terminal device 30 is limited. When the temperature or humidity of the room where the air conditioner 1 is high continues, the operation state is changed based on the operation change command supplied from the terminal device 30, thereby It can prevent the temperature and humidity of a room from continuing high.

Furthermore, in the air conditioner 1 of the present embodiment, when the operation in the forced operation mode or the notification mode is performed, the operation cannot be stopped based on the operation change command supplied from the terminal device 30. It is possible to prevent the operation of the air conditioner 1 from being stopped by the operation of the terminal device 30 when the operation in the mode or the notification mode is performed.

As mentioned above, although embodiment of this invention was described based on drawing, it should be thought that a specific structure is not limited to these embodiment. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and further includes all modifications within the meaning and scope equivalent to the scope of claims for patent.

For example, in the above-described embodiment, when switching to the forced operation mode or the notification mode, the case where the operation stop operation of the air conditioner cannot be performed by the user terminal device has been described, but the operation change supplied from the terminal device The effect of the present invention is obtained when the change of the operating state of the air conditioner based on the command is restricted. Therefore, in the present invention, the terminal device may be restricted so that an operation other than the operation stop operation of the air conditioner cannot be performed. For example, a set temperature changing operation that makes it impossible to reduce the indoor temperature and the indoor humidity is performed. It may be restricted so that it cannot.

Further, in the above-described embodiment, the forced operation is automatically started based on the room temperature and the room humidity in the forced operation mode, but the forced operation is automatically started based on the room temperature in the forced operation mode. Good. In this case, the determination diagram shown in FIG. 6 is used as the determination diagram for starting the forced operation. In the determination diagram of FIG. 6, a high temperature zone, a monitoring zone, and a standby zone are set. The high temperature zone is a region where the room temperature is 28 degrees or more, the standby zone is a region where the room temperature is less than 27 degrees, and the monitoring zone is a region where the room temperature is 27 degrees or more and less than 28 degrees. When the room temperature is in the high temperature zone, the cooling operation (forced operation) is started. When the room temperature is in the monitoring zone, the air blowing operation is performed. When the room temperature is in the standby zone, no cooling operation or air blowing operation is performed. The control in the forced operation mode of the air conditioner is performed based on the room temperature and the room humidity in the embodiment, but differs in that it is performed based on the room temperature, but the others are shown in FIG. 4 of the embodiment. This is performed in the same manner as the control described above. The same applies to the notification mode, and in the notification mode, notification that prompts the start of operation may be started based on the room temperature.

In the above-described embodiment, the forced operation is automatically started based on the room temperature and the room humidity in the forced operation mode. However, the forced operation is automatically started based on the room humidity in the forced operation mode. Good. The control in the forced operation mode of the air conditioner is different in that it is performed based on the indoor humidity and the indoor humidity in the embodiment, but is otherwise performed in FIG. 4 of the embodiment. The control is performed in the same manner as the control shown. The same applies to the notification mode. In the notification mode, notification that prompts the start of operation may be started based on the room humidity.

Further, in the above-described embodiment, the case where the forced operation mode in which the forced operation is automatically started and the notification mode in which the notification for prompting the operation start is automatically described has been described. And only one of the notification modes.

By using the present invention, it is possible to suppress a long-time continuation in a state where the room temperature and the room humidity are high, so that the user can be prevented from having heat stroke or the like.
