First Embodiment
Hereinafter, an air conditioner 1 according to a first embodiment of the present invention will be described.

<Whole structure of the air conditioner 1>
As shown in FIG. 1, the air conditioner 1 of the present embodiment includes an indoor unit 2 installed indoors and an outdoor unit 3 installed outdoor. The air conditioner 1 includes a refrigerant circuit in which the compressor 10, the four-way valve 11, the outdoor heat exchanger 12, the expansion valve (pressure reducing mechanism) 13, and the indoor heat exchanger 14 are connected. In the refrigerant circuit, the outdoor heat exchanger 12 is connected to the discharge port of the compressor 10 via the four-way valve 11, and the expansion valve 13 is connected to the outdoor heat exchanger 12. Then, one end of the indoor heat exchanger 14 is connected to the expansion valve 13, and the other end of the indoor heat exchanger 14 is connected to the suction port of the compressor 10 via the four-way valve 11.

  The air conditioner 1 can perform any one of an automatic operation, a cooling operation, a heating operation, a dehumidifying operation, and a blowing operation, and one of the operations is selected by the controller to perform an operation start operation or an operation. A switching operation or an operation stop operation can be performed. In addition, the controller can set the set temperature of the room temperature.

  In the cooling operation and the dehumidifying operation, as indicated by the solid line arrows in the figure, the refrigerant discharged from the compressor 10 flows from the four-way valve 11 to the outdoor heat exchanger 12, the expansion valve 13, and the indoor heat exchanger 14 in this order. A cooling cycle or dehumidifying cycle is formed in which the refrigerant having passed through the 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, the refrigerant discharged from the compressor 10 is switched from the four-way valve 11 to the indoor heat exchanger 14, the expansion valve 13, the outdoor heat exchanger as shown by the broken arrow in the figure when the four-way valve 11 is switched. A heating cycle is formed, which flows in order to 12 and the refrigerant passing through the outdoor heat exchanger 12 returns to the compressor 10 through the four-way valve 11. That is, the indoor heat exchanger 14 functions as a condenser, and the outdoor heat exchanger 12 functions as an evaporator.

  In the indoor unit 2, an indoor fan 16 facing the indoor heat exchanger 14 is disposed. At the outlet of the indoor unit 2, an upper and lower flap 17 is disposed which changes the blowing direction in the vertical direction. Then, as shown in FIG. 1, an indoor temperature sensor (indoor temperature detection means) 21 for detecting the indoor temperature and an indoor humidity sensor (indoor humidity detection means) 22 for detecting the indoor humidity are attached to the indoor unit 2.

  As shown in FIG. 2, the control unit of the air conditioner 1 includes a compressor 10, a four-way valve 11, an expansion valve 13, a motor 16a for driving the indoor fan 16, and a motor 17a for driving the upper and lower flaps 17. The indoor temperature sensor 21, the indoor humidity sensor 22, and the controller 30 are connected. Therefore, the control unit is based on a command from the controller 30 (such as a start operation or a set temperature of the room temperature), the room temperature detected by the room temperature sensor 21, and the room humidity detected by the room humidity sensor 22. , Control the operation of the air conditioner 1.

  Here, the controller 30 will be described with reference to FIG. FIG. 3A shows a state in which the lid 33 on the upper surface of the controller 30 is opened.

  The left portion 31 of the controller 30 includes a display portion 41, a temperature control dial 42 disposed below the display portion 41, an operation start button 43 disposed inside the temperature control dial 42, and a temperature control dial 42. A stop button 44 disposed on the lower right side is provided. Further, in the right part 32 of the controller 30, a driving selection dial 45, an air volume selection dial 46, and a wind direction selection dial 47 are provided in order from the top.

  On the display unit 41, an operation display unit 41a, a set temperature display unit 41b, and an operation mode display unit 41c are displayed. On the operation display unit 41a, the operation (automatic, cooling, heating, dehumidifying or air blowing operation) selected by the operation selection dial 45 is displayed. Further, the temperature changed by rotating the temperature adjustment dial 42 is displayed on the set temperature display section 41 b.

  The temperature adjustment dial 42 is for changing the set temperature. The set temperature can be raised by rotating the temperature adjustment dial 42 to the right, and the set temperature can be reduced by rotating the temperature adjustment dial 42 to the left. When the operation start button 43 is pressed, the operation selected by the operation selection dial 45 is started, and when the stop button 44 is pressed during operation, the operation is stopped.

  Automatic, cooling, heating, dehumidification, and ventilation can be switched and selected by the operation selection dial 45 of the right part 32 of the controller 30. With the air volume selection dial 46, the air volume can be switched between automatic, fine (small amount), weak (small amount) and strong (large amount). The wind direction selection dial 47 can switch the wind direction automatically, upward (upward), middle (horizontally) or downward (downward) for selection.

  And the cover part which covers the whole is provided in the back surface of the controller 30, and the state which removed the cover part is shown in FIG.3 (b). As shown in FIG. 3B, the mode switching unit 50 is provided on the back surface of the controller 30 when the lid is removed. The mode switching unit 50 can switch the high temperature prevention mode of the air conditioner 1 to any of the forced operation mode, the notification mode, and the off mode.

  In the forced operation mode, when the room is in a high temperature state or high humidity state, the forced operation is automatically started based on the indoor temperature and the indoor humidity. Therefore, when the 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 to the controller 30 when the room is in the high temperature state or the high humidity state. , Indoor temperature and indoor humidity decrease.

  Then, when switching to the forced operation mode, the user can not select the heating (heating operation) with the controller 30 to perform the operation start operation, and selects the automatic (automatic operation) to start the operation of the automatic operation. Only operations can be performed. In the air conditioner 1, when the automatic operation is started by the user, 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 to change the blowing direction upward.

  In the notification mode, when the room is in a high temperature state or a high humidity state, a notification to automatically start the operation is automatically performed based on the room temperature and the room humidity.

  In the air conditioner 1, when determining whether to start forced operation in the forced operation mode or when determining whether to start notification in the notification mode, a determination diagram for the indoor temperature and the indoor humidity is used. In the determination diagram, as shown in FIG. 4, the vertical axis represents room humidity (relative humidity), and the horizontal axis represents room temperature.

  The forced operation mode will be described below.

  FIG. 4 is an example of a determination diagram in the forced operation mode, in which a high temperature zone, a monitoring zone, and a standby zone are set. The high temperature zone is a region where the room is in a high temperature state or high humidity state, and it is necessary to reduce the room temperature and the room humidity. The standby zone is an area far from the high temperature zone, and is an area where it is not necessary to reduce the room temperature or the room humidity. The monitoring zone is an area close to the high temperature zone, and is an area in which the indoor temperature and the indoor humidity are easily changed to the high temperature zone.

In the determination diagram of FIG. 4, points A to F indicate points which are the following room temperature and room humidity. Point A: indoor temperature is 27 degrees, indoor humidity is 100% point B: indoor temperature is 27 degrees, indoor humidity is y ₁ between 70-80%, point C : Indoor temperature is 33 degrees, indoor humidity is 30% point D: indoor temperature is 28 degrees, indoor humidity is 100% point E: indoor temperature is 28 degrees, indoor Humidity is y ₂ between 70-80% · Point F: Indoor temperature is 34 ° C and indoor humidity is y ₃ between 30-40%

Then, a line l ₁ of connecting the points A and B and the point C, a line between the waiting zone and monitoring zone, a line l ₂ connecting a point D and point E and point F, and monitoring zone It is a line between the high temperature zone. Accordingly, as shown in the decision diagram of Figure 4, standby zone, a lower left region of the line l _1, the high temperature zone, the upper right area (indoor temperature and the indoor humidity of the line l ₂ is on line l ₂ a certain including the case), the monitoring zone is an area sandwiched between the high temperature zone and the standby zone (indoor temperature and the indoor humidity which might reside on a line l _1).

  Therefore, when the operation is switched to the forced operation mode when the operation of the air conditioner 1 is stopped, 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. Therefore, the driving operation in each zone after switching to the forced driving mode will be described.

  When the room temperature and the room humidity are in the high temperature zone, the room temperature and the room humidity need to be reduced, so the cooling operation (forced operation) is started. The cooling operation in the forced operation mode in the air conditioner 1 is a cooling operation at a set temperature of 28 ° C. Then, when the room temperature falls by 1 degree or more below the set temperature (when the room temperature becomes 27 degrees or less), the cooling operation is in the thermo-off state. Here, in the thermo-off state, 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 flow rate is lower than in the cooling operation, and the upper and lower flaps 17 are disposed 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 easily changed to the high temperature zone. Therefore, the room temperature and the room humidity need to be properly detected. In the blowing operation, the compressor is stopped and the indoor fan 16 of the indoor unit is driven. In the air conditioner 1, since the indoor temperature sensor 21 and the indoor humidity sensor 22 are attached to the inside of the indoor unit 2, when the upper and lower flaps 17 are closed when the operation is stopped, heat is accumulated inside the indoor unit In some cases, room temperature and room humidity can not be detected properly. Therefore, when the room temperature and the room humidity are in the monitoring zone, the air flows 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 flow rate is lower than the air flow rate in the cooling operation, and the upper and lower flaps 17 are disposed near the upper end of the movable range to make the blowing direction upward. change.

  When the room temperature and the room humidity are in the standby zone, the room temperature and the room humidity do not need to be reduced because the room temperature and the room humidity are not far from the high temperature zone.

  Thus, in the present 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. In addition, after the cooling operation is started, the cooling operation is stopped when the thermo-off state continues for a predetermined time.

  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 50 (see FIG. 3B) of the controller 30 switches to the forced operation mode (step S1). Here, the case where the room temperature and the room humidity when switched to the forced operation mode are in the standby zone (see FIG. 4) will be described.

  In the forced operation mode, it is determined whether the indoor temperature detected by the indoor temperature sensor 21 and the indoor humidity detected by the indoor 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 to change to the high temperature zone after changing from the standby zone to the monitoring 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 approach the high temperature zone where the cooling operation needs to be started.

  When it is determined that the indoor temperature and the indoor 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 inside 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, if it is determined that the room temperature and the room humidity are not in the monitoring zone (step S2: NO), the room temperature and the room humidity are in the standby zone, so it is determined whether the room temperature and the room humidity are in the monitoring zone (Step S2).

  Then, after the air blowing operation is started in step S3, it is determined whether the indoor temperature detected by the indoor temperature sensor 21 and the indoor humidity detected by the indoor humidity sensor 22 are in the monitoring zone (step S4). If 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 Thus, the 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 change to the standby zone or the high temperature zone after the air blowing operation is started. . Therefore, it is determined whether the room temperature and the room humidity are in the standby zone (step S5). When it is determined that the room temperature and the room humidity are in the standby zone (Step S4: YES), the room temperature and the indoor humidity change from the monitoring zone close to the high temperature zone to the standby zone, so the air blowing operation is stopped. (Step S6). Then, it transfers to step S2 and it is judged whether room temperature and room humidity exist in a monitoring zone. On the other hand, if 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. The cooling operation is started (step S7).

  After the cooling operation is started, it is determined whether the cooling operation is in the thermo-off state based on the indoor temperature detected by the indoor temperature sensor 21 and the set temperature (step S8). In the air conditioner 1, when the cooling operation is at the set temperature of 28 ° C. and the room temperature becomes 27 ° C. or lower, the thermostat is turned off. Therefore, in step S8, it is determined whether the cooling operation is in the thermo-off state based on whether the indoor temperature is 27 ° C. or lower. Then, if it is determined that the thermo-off state is not set (step S8: NO), the room temperature is higher than 27 ° C., so the process proceeds to step S7 and the cooling operation is continued.

  On the other hand, when it is determined that the cooling operation is in the thermo-off state (step S8: YES), in the thermo-off state, it is determined whether the indoor temperature detected by the indoor temperature sensor 21 has changed to a temperature higher than the set temperature ( Step S9). If it is determined that the indoor temperature has changed to a temperature higher than the set temperature (step S9: YES), the process proceeds to step S7, and the cooling operation is started. If it is determined that the indoor temperature has not changed to a temperature higher than the set temperature (step S9: NO), the thermo-off state is continued.

  Then, when the thermo-off state is continued, it is determined whether a predetermined time has elapsed (step S10). When it is determined that the predetermined time has elapsed in the thermo-off state (step S10: YES), the cooling operation is stopped (step S11). In the air conditioner 1, since the cooling operation is stopped after a predetermined time has elapsed in the thermo-off state, the cooling operation is immediately started even when the indoor temperature and the indoor humidity rise when the cooling operation is stopped. Can be prevented.

  On the other hand, if it is determined that the predetermined time has not elapsed in the thermo-off state (step S10: NO), the process proceeds to step S9 to determine whether the indoor temperature has changed to a temperature higher than the set temperature.

<Features of the air conditioner of the present embodiment>
In the air conditioner 1 of the present embodiment, when the room is in a state where it is necessary to reduce the room temperature and the room humidity, the cooling operation to reduce the room temperature and the room humidity is automatically started. Therefore, it is possible to prevent the user from becoming a heat stroke or the like because the room temperature and the room humidity can be prevented from continuing for a long time in a high state.

  Further, in the air conditioner 1 of the present embodiment, it is determined whether to start the cooling operation based on the indoor temperature and the indoor humidity in a state where the indoor fan 16 is driven and the air flows inside the indoor unit 2. Even when the indoor temperature sensor 21 and the indoor humidity sensor 22 are inside the indoor unit 2 and heat is absorbed inside the indoor unit 2 at the time of operation stop, the indoor temperature and the indoor humidity can be properly detected.

  Furthermore, in the air conditioner 1 of the present embodiment, when the monitoring zone is near the high temperature zone where the cooling operation is started, the room temperature and the indoor humidity approach the range where the cooling operation is started. , And the indoor fan 16 can be driven. Therefore, it is possible to properly detect the room temperature and the room humidity and determine whether to start the cooling operation.

  In addition, in the air conditioner 1 of the present embodiment, after the indoor fan 16 is driven, the indoor temperature and humidity are in the monitoring zone near the high temperature zone where the cooling operation is started. Can continue to drive. Therefore, it is possible to properly detect the room temperature and the room humidity and determine whether to start the cooling operation.

  Further, in the air conditioner 1 of the present embodiment, the cooling operation is started when the indoor temperature and the indoor humidity are in the high temperature zone by setting the high temperature zone to a range in which the indoor temperature and the indoor humidity need to be reduced. it can.

  Furthermore, in the air conditioner 1 of the present embodiment, the load on the user can be reduced by making the air volume when the indoor fan 16 is driven smaller than that during the cooling operation.

  In addition, in the air conditioner 1 of the present embodiment, when the indoor fan 16 is driven, the direction of the upper and lower flaps 17 of the indoor unit 2 is changed to change the blowing direction upward, from the indoor unit 2 Because the user does not directly blow the user's wind, the burden on the user can be reduced.

  Further, in the air conditioner 1 of the present embodiment, in the forced operation mode, the controller 30 can not select the heating operation and perform the operation start operation, so that the heating operation can be prevented from being erroneously started.

  Furthermore, in the air conditioner 1 of the present embodiment, only the automatic operation can be selected and the operation start operation can be performed in the forced operation mode, so the heating operation is performed when the outside air temperature is low.

Second Embodiment
Next, a second embodiment of the present invention will be described with reference to FIG. The air conditioner according to the second embodiment differs from the air conditioner according to the first embodiment in the timing when the cooling operation is started in the forced operation mode. In addition, since the other structure is the same as that of the said 1st Embodiment, the description is suitably abbreviate | omitted using the same code | symbol.

  In the air conditioner of the second embodiment, the determination diagram for determining the start of forced operation is the same as the determination diagram (FIG. 4) in the air conditioner 1 of the first embodiment.

  And in the air conditioner of the first embodiment, in the forced operation mode, the cooling operation is started when the indoor temperature and the indoor humidity are in the high temperature zone, whereas in the air conditioner of the second embodiment, the air conditioner is forced. In the operation mode, the cooling operation is started when the room temperature and the room humidity are in the high temperature zone, and the cooling operation is started when the room temperature and the room humidity are in the monitoring zone for a predetermined time.

  In the air conditioner of the second embodiment, as in the air conditioner of the first embodiment, in the forced operation mode, the cooling operation is stopped when a predetermined time has elapsed in the thermo-off state of the cooling operation.

  Next, control in the forced operation mode of the air conditioner of the second embodiment will be described.

  First, when the operation of the air conditioner is stopped, the mode switching unit 50 (see FIG. 3B) of the controller switches the mode to the forced operation mode (step S21). Here, the case where the indoor temperature and the indoor humidity when switched to the forced operation mode are in the standby zone will be described.

  In the forced operation mode, it is determined whether the indoor temperature detected by the indoor temperature sensor 21 and the indoor humidity detected by the indoor humidity sensor 22 are in the monitoring zone (step S22). When the room temperature and the room humidity change from the standby zone to the high temperature zone, it is considered to change to the high temperature zone after changing from the standby zone to the monitoring zone. Therefore, in step S22, it is determined whether the room temperature and the room humidity approach a high temperature zone where the cooling operation needs to be started, based on whether the room temperature and the room humidity are in the monitoring zone.

  When it is determined that the indoor temperature and the indoor humidity are in the monitoring zone (step S22: YES), the indoor fan 16 is driven to start the air blowing operation (step S23). When the room temperature and the room humidity are in the monitoring zone near the high temperature zone, the air flows inside 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 S22: NO), the room temperature and the room humidity are in the standby zone, so the process proceeds to step S22 and the room temperature and the room humidity are Continue to determine if it is in the monitoring zone.

  Then, after the air blowing operation is started in step S23, it is determined whether the indoor temperature detected by the indoor temperature sensor 21 and the indoor humidity detected by the indoor humidity sensor 22 are in the monitoring zone (step S24). If it is determined that the room temperature and the room humidity are not in the monitoring zone (step S24: NO), it is considered that the room temperature and the room humidity change to the standby zone or the high temperature zone after the air blowing operation is started. Therefore, it is determined whether the room temperature and the room humidity are in the standby zone (step S25). If it is determined that the indoor temperature and the indoor humidity are in the standby zone (step S25: YES), the indoor temperature and the indoor humidity change from the monitoring zone close to the high temperature zone to the standby zone, so the air blowing operation is stopped (step S26) The process proceeds to step S22, and the determination as to whether the room temperature and the room humidity are in the monitoring zone is continued. On the other hand, if it is determined in step S25 that the room temperature and the room humidity are not in the standby zone (step S25: 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. Because of this, the cooling operation is started (step S27).

  On the other hand, after the air blowing operation is started in step S23, when it is determined that the room temperature and the room humidity are in the monitoring zone (step S24: YES), a predetermined time after the room temperature and the room humidity become the monitoring zone Is judged (step S28). When it is determined that the room temperature and the room humidity in the monitoring zone have reached a predetermined time (step S28: YES), the room temperature and the room humidity are in the high temperature zone because the predetermined time has elapsed in the state close to the high temperature zone. The cooling operation is started (step S27). On the other hand, when it is determined that the room temperature and the room humidity in the monitoring zone have not passed the predetermined time (step S28: NO), the process proceeds to step S23, and the air blowing operation is continued.

  After the cooling operation is started in step S27, it is determined whether the cooling operation is in the thermo-off state based on the indoor temperature detected by the indoor temperature sensor 21 and the set temperature (step S29). In the air conditioner, when the cooling operation is at a set temperature of 28 ° C. and the room temperature becomes 27 ° C. or lower, the thermo-off state is established. Therefore, in step S31, it is determined whether the forced operation is in the thermo-off state based on whether the room temperature is 27 ° C. or lower. Then, when it is determined that it is not in the thermo-off state (step S29: NO), the room temperature is higher than 27 ° C., so that the process proceeds to step S27 and the cooling operation is continued.

  On the other hand, when it is determined that the cooling operation is in the thermo-off state (step S29: YES), in the thermo-off state, it is determined whether the indoor temperature detected by the indoor temperature sensor 21 has changed to a temperature higher than the set temperature ( Step S30). If it is determined that the indoor temperature has changed to a temperature higher than the set temperature (step S30: YES), the process proceeds to step S27, and the cooling operation is started. If it is determined that the indoor temperature has not changed to a temperature higher than the set temperature (step S30: NO), the thermo-off state is continued.

  When the thermo-off state is continued, it is determined whether a predetermined time has elapsed (step S31). If it is determined that the predetermined time has elapsed in the thermo-off state (step S31: YES), the cooling operation is stopped (step S32). In the air conditioner, the cooling operation is stopped after a predetermined time has elapsed in the thermo-off state, so that when the cooling operation is stopped, the cooling operation is immediately started even if the room temperature and the room humidity rise. It can prevent.

  On the other hand, when it is determined that the predetermined time has not elapsed in the thermo-off state (step S31: NO), the process proceeds to step S30, and it is determined whether the indoor temperature has changed to a temperature higher than the set temperature.

<Features of the air conditioner of the present embodiment>
In the air conditioner 1 of the present embodiment, as in the air conditioner 1 of the first embodiment, when the room is in a state where the room temperature and the room humidity need to be reduced, the room temperature and the room humidity are reduced. The cooling operation is automatically started. Therefore, it is possible to prevent the user from becoming a heat stroke or the like because the room temperature and the room humidity can be prevented from continuing for a long time in a high state.

  Moreover, in the air conditioner 1 of the present embodiment, the cooling operation is automatically started when the indoor temperature and the indoor humidity are in the monitoring zone for a predetermined time after the indoor fan 16 is driven. Therefore, the room temperature and the room humidity can be reduced by starting the cooling operation before the room temperature and the room humidity require the cooling operation.

Third Embodiment
Next, a third embodiment of the present invention will be described with reference to FIG. The air conditioner according to the third embodiment differs from the air conditioner according to the first embodiment in the timing when the cooling operation is started in the forced operation mode. In addition, since the other structure is the same as that of the said 1st Embodiment, the description is suitably abbreviate | omitted using the same code | symbol.

  In the air conditioner of the third embodiment, the determination diagram for determining the start of forced operation is the same as the determination diagram (FIG. 4) in the air conditioner 1 of the first embodiment.

  And in the air conditioner of the first embodiment, in the forced operation mode, the cooling operation is started when the room temperature and the room humidity are in the high temperature zone, while in the air conditioner of the third embodiment, In the forced operation mode, the cooling operation is started when the room temperature or the room humidity after the indoor fan 16 is driven is higher than the room temperature or the room humidity before the indoor fan 16 is driven.

  In the air conditioner of the third embodiment, as in the air conditioner of the first embodiment, in the forced operation mode, the cooling operation is stopped when a predetermined time has elapsed in the thermo-off state of the cooling operation.

  Next, control in the forced operation mode of the air conditioner will be described.

  First, when the operation of the air conditioner is stopped, the mode switching unit 50 (see FIG. 3B) of the controller switches the mode to the forced operation mode (step S41). Here, the case where the indoor temperature and the indoor humidity when switched to the forced operation mode are in the standby zone will be described.

  In the forced operation mode, it is determined whether the indoor temperature detected by the indoor temperature sensor 21 and the indoor humidity detected by the indoor humidity sensor 22 are in the monitoring zone (step S42). When the room temperature and the room humidity change from the standby zone to the high temperature zone, it is considered to change to the high temperature zone after changing from the standby zone to the monitoring zone. Therefore, in step S42, it is determined whether the room temperature and the room humidity approach a high temperature zone where the cooling operation needs to be started, based on whether the room temperature and the room humidity are in the monitoring zone.

  When it is determined that the indoor temperature and the indoor humidity are in the monitoring zone (step S42: YES), the indoor fan 16 is driven to start the air blowing operation (step S43). When the room temperature and the room humidity are in the monitoring zone near the high temperature zone, the air flows inside 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, if it is determined that the room temperature and the room humidity are not in the monitoring zone (step S42: NO), it is considered that the room temperature and the room humidity are in the standby zone, so the process proceeds to step S2 and the room temperature and room temperature Continue to determine if the indoor humidity is in the monitoring zone.

  Then, after the air blowing operation is started in step S43, it is determined whether the room temperature detected by the room temperature sensor 21 or the room humidity detected by the room humidity sensor 22 is higher than before the air blowing operation is started ( Step S44). If it is determined that the room temperature and the room humidity have risen before the start of the air blowing operation (step S44: YES), the room temperature and the room humidity approach a high temperature zone where the cooling operation needs to be started or It is considered that the temperature and the indoor humidity have changed to the high temperature zone. For this reason, since it is necessary to reduce the room temperature and the room humidity, the cooling operation is started (step S45).

  On the other hand, if it is determined that the room temperature and the room humidity have not risen before the start of the air blowing operation (step S44: NO), the process proceeds to step S43, and the air blowing operation is continued.

  After the cooling operation is started in step S45, it is determined whether the cooling operation is in the thermo-off state based on the indoor temperature detected by the indoor temperature sensor 21 and the set temperature (step S46). In the air conditioner, when the cooling operation is at a set temperature of 28 ° C. and the room temperature becomes 27 ° C. or lower, the thermo-off state is established. Therefore, in step S46, it is determined whether the cooling operation is in the thermo-off state based on whether the room temperature is 27 ° C. or lower. Then, if it is determined that it is not in the thermo-off state (step S46: NO), the room temperature is higher than 27 ° C., so the process proceeds to step S45 and the cooling operation is continued.

  On the other hand, when it is determined that the cooling operation is in the thermo-off state (step S46: YES), in the thermo-off state, it is determined whether the indoor temperature detected by the indoor temperature sensor 21 has changed to a temperature higher than the set temperature ( Step S47). If it is determined that the indoor temperature has changed to a temperature higher than the set temperature (step S47: YES), the process proceeds to step S45, and the cooling operation is started. If it is determined that the room temperature has not changed to a temperature higher than the set temperature (NO in step S47), the thermo-off state is continued.

  Then, if the thermo-off state is continued, it is determined whether a predetermined time has elapsed (step S48). If it is determined that the predetermined time has elapsed in the thermo-off state (step S48: YES), the cooling operation is stopped (step S49). In the air conditioner, the cooling operation is stopped after a predetermined time has elapsed in the thermo-off state, so that when the cooling operation is stopped, the cooling operation is immediately started even if the room temperature and the room humidity rise. It can prevent.

  On the other hand, when it is determined that the predetermined time has not elapsed in the thermo-off state (step S48: NO), the process proceeds to step S47, and it is determined whether the indoor temperature has changed to a temperature higher than the set temperature.

<Features of the air conditioner of the present embodiment>
In the air conditioner according to the present embodiment, as in the air conditioner 1 according to the first embodiment, when the room is in a state where the room temperature and the room humidity need to be reduced, the room temperature and the room humidity are reduced. The cooling operation is automatically started. Therefore, it is possible to prevent the user from becoming a heat stroke or the like because the room temperature and the room humidity can be prevented from continuing for a long time in a high state.

  In the air conditioner 1 of the present embodiment, cooling is performed when the indoor temperature or the indoor humidity after the indoor fan 16 is driven is higher than the indoor temperature or the indoor humidity before the indoor fan 16 is driven. Driving is started. Therefore, the cooling operation can be started before the cooling operation is required to reduce the room temperature and / or the room humidity.

Fourth Embodiment
Next, a fourth embodiment of the present invention will be described with reference to FIGS. The air conditioner according to the fourth embodiment differs from the air conditioner according to the first embodiment in the timing when the air blowing operation is started in the forced operation mode and the timing when the cooling operation is started. In addition, since the other structure is the same as that of the said 1st Embodiment, the description is suitably abbreviate | omitted using the same code | symbol.

  In the air conditioner of the fourth embodiment, the determination diagram shown in FIG. 8 is used for the determination diagram that determines the start of the cooling operation. The vertical axis of the determination diagram indicates the indoor humidity (relative humidity), and the horizontal axis indicates the indoor temperature.

  As shown in FIG. 8, the high temperature zone and the standby zone are set in the determination diagram. The high temperature zone shown in FIG. 8 is an area where the room temperature and the room humidity need to be reduced, and the standby zone is an area where the room temperature and the room humidity do not need to be reduced. And in the air conditioner of a 4th embodiment, since a monitoring zone is not set, after switching to forced operation mode, ventilation operation is started regularly. The air blowing operation is stopped when a predetermined air blowing time has elapsed.

As shown in the decision diagram of Figure 8, the waiting zone is a lower left region in FIG. 4 and the same line l ₂ of the first embodiment, the high temperature zone, upper right region of a line l ₂ (room temperature and it is including when the indoor humidity is on the line l _2).

  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 a cooling operation with a set temperature of 28 ° C. is started. Further, the cooling operation in the forced operation mode is in the thermo-off state when the room temperature becomes 27 degrees or lower.

  On the other hand, when the room temperature and the room humidity are in the standby zone, the room temperature and the room humidity do not need to be reduced, but the standby zone is an area far from the high temperature zone and an area near the high temperature zone Since the temperature and the indoor humidity tend to change to the high temperature zone), when the room temperature or the indoor humidity tends to rise, the cooling operation is started because the high temperature zone is approached. On the other hand, when the room temperature and the room humidity are in the standby zone and the room temperature or the room humidity does not tend to rise, the cooling operation is not started. Therefore, when the room temperature and the room humidity are in the standby zone, after the air blowing operation is started, the air blowing operation is stopped when the predetermined air blowing time has elapsed without the cooling operation being started.

  As described above, in the air conditioner according to the first embodiment, the cooling operation is started when the room temperature and the room humidity are in the high temperature zone in the forced operation mode, whereas the air conditioner according to the fourth embodiment is In the forced operation mode, the cooling operation is started when the room temperature and the room humidity are in the high temperature zone, and the room temperature or the room humidity (at least one of the room temperature and the room humidity) rises after the air blowing operation is started. The cooling operation is started when there is a tendency.

  In the air conditioner of the fourth embodiment, the cooling operation is stopped when a predetermined time has elapsed in the thermo-off state in the forced operation mode, as in the air conditioner of the first embodiment.

  Next, control in the forced operation mode of the air conditioner will be described.

  First, when the operation of the air conditioner is stopped, the mode switching unit 50 (see FIG. 3B) of the controller 30 switches to the forced operation mode (step S51). Here, the case where the indoor temperature and the indoor humidity when switched to the forced operation mode are in the standby zone will be described.

  In the forced operation mode, it is determined whether a predetermined time has elapsed (step S52). If it is determined that the predetermined time has not elapsed (step S52: NO), the determination is continued until the predetermined time has elapsed. And when predetermined time passes (step S52: YES), a ventilation operation is started (S53). After the air blowing operation is started, it is determined whether the indoor temperature detected by the indoor temperature sensor 21 and the indoor humidity detected by the indoor humidity sensor 22 are in the high temperature zone (step S54). If it is determined that the indoor temperature and the indoor humidity are in the high temperature zone (step S54: YES), the cooling operation is started (step S55).

  On the other hand, when it is determined that the indoor temperature and the indoor humidity are not in the high temperature zone (step S54: NO), it is determined whether a predetermined air blowing time has elapsed after the air blowing operation is started (step S56). After the air blowing operation is started, if it is determined that the predetermined air blowing time has elapsed (step S56: YES), the air blowing operation is stopped (step S57). Then, the process proceeds to step S52, and after the air blowing operation is started in step S53, it is determined whether a predetermined air blowing time has elapsed.

  On the other hand, when it is determined that the predetermined air blowing time has not elapsed after the air blowing operation is started in step S53 (step S56: NO), the room detected by the indoor temperature sensor 21 after the air blowing operation is started. It is determined whether the temperature or the indoor humidity detected by the indoor humidity sensor 22 tends to increase (step S58). If it is determined that the indoor temperature or the indoor humidity tends to rise (step S58: YES), the room temperature or the indoor humidity approaches the high temperature zone, and the cooling operation is started (step S55). On the other hand, when it is determined that the room temperature or the room humidity does not tend to increase (step S58: NO), the process proceeds to step S56, and after the air blowing operation is started, it is determined whether a predetermined air blowing time has elapsed.

  After the cooling operation is started in step S55, it is determined whether the cooling operation is in the thermo-off state based on the indoor temperature detected by the indoor temperature sensor 21 and the set temperature (step S59). In the air conditioner, when the cooling operation is at a set temperature of 28 ° C. and the room temperature becomes 27 ° C. or lower, the thermo-off state is established. Therefore, in step S59, it is determined whether the cooling operation is in the thermo-off state based on whether the room temperature is 27 ° C. or lower. Then, if it is determined that the thermostat is not in the OFF state (step S59: NO), the room temperature is higher than 27 ° C., so the process proceeds to step S55 and the cooling operation is continued.

  On the other hand, when it is determined that the cooling operation is in the thermo-off state (step S59: YES), in the thermo-off state, it is determined whether the indoor temperature detected by the indoor temperature sensor 21 has changed to a temperature higher than the set temperature ( Step S60). If it is determined that the indoor temperature has changed to a temperature higher than the set temperature (step S60: YES), the process proceeds to step S55 and the cooling operation is performed. If it is determined that the room temperature has not changed to a temperature higher than the set temperature (step S60: NO), the thermo-off state is continued.

  Then, if the thermo-off state is continued, it is determined whether a predetermined time has elapsed (step S61). If it is determined that the predetermined time has elapsed in the thermo-off state (step S61: YES), the cooling operation is stopped (step S62). In the air conditioner, the cooling operation is stopped after a predetermined time has elapsed in the thermo-off state, so that when the cooling operation is stopped, the cooling operation is immediately started even if the room temperature and the room humidity rise. It can prevent.

  On the other hand, when it is determined that the predetermined time has not elapsed in the thermo-off state (step S61: NO), the process proceeds to step S60, and it is determined whether the indoor temperature has changed to a temperature higher than the set temperature.

<Features of the air conditioner of the present embodiment>
In the air conditioner according to the present embodiment, as in the air conditioner 1 according to the first embodiment, when the room is in a state where the room temperature and the room humidity need to be reduced, the room temperature and the room humidity are reduced. The cooling operation is automatically started. Therefore, it is possible to prevent the user from becoming a heat stroke or the like because the room temperature and the room humidity can be prevented from continuing for a long time in a high state.

  Further, in the air conditioner 1 of the present embodiment, since the indoor fan 16 is periodically driven in the forced operation mode, it is possible to properly detect the indoor temperature and the indoor humidity to determine whether to start the cooling operation.

  Furthermore, in the air conditioner 1 of the present embodiment, the cooling operation is started when at least one of the indoor temperature and the indoor humidity tends to increase after the indoor fan 16 is driven. Therefore, the room temperature and the room humidity can be reduced by starting the cooling operation before the cooling operation is required.

Fifth Embodiment
Next, a fifth embodiment of the present invention will be described with reference to FIGS. The air conditioner according to the fifth embodiment differs from the air conditioner according to the first embodiment at the time when forced operation is started. In addition, since the other structure is the same as that of the said 1st Embodiment, the description is suitably abbreviate | omitted using the same code | symbol.

  In the air conditioner of the fifth embodiment, the determination diagram shown in FIG. 10 is used as the determination diagram for determining the start of forced operation. The vertical axis of the determination diagram indicates the indoor humidity (relative humidity), and the horizontal axis indicates the indoor temperature.

  As shown in FIG. 10, a high temperature zone, a high humidity zone, a monitoring zone, and a standby zone are set in the determination diagram. The high temperature zone shown in FIG. 10 is an area where it is necessary to reduce the room temperature and the room humidity. The high humidity zone is an area where the indoor humidity needs to be reduced. The standby zone is an area far from the high temperature zone and the high humidity zone, and is an area where there is no need to reduce the room temperature or the room humidity. The monitoring zone is an area close to the high temperature zone and the high humidity zone, and is an area in which the indoor temperature and the indoor humidity are easily changed to the high temperature zone and the high humidity zone.

In the determination of FIG 10, A ₁ point to E ₁ point shows that it is the room temperature and the indoor humidity below. A ₁ point: the room temperature is 25 degrees and the indoor humidity is y ₄ between 80 and 90% B ₁ point: the room temperature is 33 degrees and the room humidity is 30% C ₁ point: indoor temperature is 25 ° C., indoor humidity is 100% D. ₁ point: indoor temperature is 28 ° C., indoor humidity is y ₂ between 70-80%, E ₁ point: the indoor temperature is 34 degrees and the indoor humidity is y ₃ between 30-40% · point ₁ F: the indoor temperature is 28 degrees and the indoor humidity is 100%

Then, the line l ₁₁ connected to _one point and B ₁ point A is a line between the waiting zone and monitoring zone, the line l ₁₂ connected to _one point and D _point C is monitored zone and high humidity a line between the zones, a line a line l ₁₃ connected to _one point and E ₁ point D is a line between the monitoring zone and the hot zone, which connects the _point and F _point D l ₁₄ is a line between the high humidity zone and the high temperature zone.

Accordingly, as shown in the decision diagram of Figure 10, the waiting zone is a lower left region of the line l _11, hot zone, right area (indoor temperature and the indoor humidity of the line l ₁₄ at the top right of the line l ₁₃ a but which might reside on the line l ₁₃ above and l _14), high humidity zones, upper right in the left area (indoor temperature and the indoor humidity of the line l ₁₄ line l ₁₂ is on the line l ₁₂ The monitoring zone is a high temperature zone and an area between the high humidity zone and the standby zone (including the case where the room temperature and the room humidity are on the line ₁₁ ).

  Therefore, when the air conditioner is shut down and switched to the forced operation mode, the operation operation is different when the room temperature and the room humidity are in the high temperature zone, the high humidity zone, the monitoring zone, and the standby zone. Therefore, the driving operation in each zone after switching to the forced driving mode will be described.

  In the present embodiment, the forced operation in the forced operation mode is either the dehumidifying operation or the cooling operation at the set temperature of 28 ° C.

  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 a cooling operation with a set temperature of 28 ° C. is started. Further, the cooling operation in the forced operation mode is in the thermo-off state when the room temperature becomes 27 degrees or lower.

  When the room temperature and humidity are in the high humidity zone, there is no need to lower the room temperature because the room temperature is lower than 28 ° C. However, since it is necessary to reduce the room humidity, the cooling operation is not started. , Dehumidification operation is started. Dehumidifying operation in forced operation mode is switched to cooling operation when room temperature and humidity are in the high humidity zone after starting dehumidification operation, and room temperature and humidity change from the high humidity zone to the monitoring zone Is stopped. In the dehumidifying operation when the room temperature and the room humidity are in the high humidity zone, the air flow rate is lower than the air flow rate in the cooling operation, and the upper and lower flaps 17 are disposed near the upper end of the movable range to make the blowing direction upward change. Then, when the cooling operation is switched after the dehumidifying operation, the air volume in the dehumidifying operation is increased to the air volume in the cooling operation, and the air volume is gradually increased in the cooling operation.

  When the room temperature and the room humidity are in the monitoring zone, the room temperature and the room humidity are easily changed to the high temperature zone and the room humidity. Therefore, it is necessary to properly detect the room temperature and the room humidity. I do.

  In addition, when the room temperature and the room humidity are in the standby zone, the room temperature and the room humidity do not need to be reduced, so the air blowing operation and the cooling operation are not performed.

  As described above, in the air conditioner of the first embodiment, the cooling operation is started when the room temperature and the room humidity are in the high temperature zone in the forced operation mode, while the air conditioner of the fifth embodiment is In the forced operation mode, the cooling operation is started when the room temperature and the room humidity are in the high temperature zone, and the dehumidifying operation is started when the room temperature and the room humidity are in the high humidity zone.

  Moreover, in the air conditioner of the fifth embodiment, the cooling operation in the forced operation mode is stopped when a predetermined time has elapsed in the thermo-off state, as in the air conditioner of the first embodiment. On the other hand, the dehumidifying operation in the forced operation mode is switched to the cooling operation when the room temperature and the room humidity change to the high temperature zone, and is stopped when the room temperature and the room humidity change to the monitoring zone.

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

  First, when the operation of the air conditioner is stopped, the mode switching unit 50 (see FIG. 3B) of the controller 30 switches to the forced operation mode (step S71). Here, the case where the indoor temperature and the indoor humidity when switched to the forced operation mode are in the standby zone will be described.

  In the forced operation mode, it is determined whether the indoor temperature detected by the indoor temperature sensor 21 and the indoor humidity detected by the indoor humidity sensor 22 are in the monitoring zone (step S72). When the room temperature and the room humidity change from the standby zone to the high temperature zone or the high humidity zone, it is considered to change to the high temperature zone or the high humidity zone after changing from the standby zone to the monitoring zone. Therefore, in step S72, based on whether the room temperature and the room humidity are in the monitoring zone, the room temperature and the room humidity are required to start the forced operation (cooling operation or dehumidifying operation) in the high temperature zone and the high humidity zone. Determine if you are approaching.

  When it is determined that the indoor temperature and the indoor humidity are in the monitoring zone (step S72: YES), the indoor fan 16 is driven to start the air blowing operation (step S73). When the room temperature and the room humidity are in the monitoring zone near the high temperature zone and the high humidity zone, the air flows inside 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 S72: NO), the room temperature and the room humidity are in the monitoring zone because the room temperature and the room humidity are considered to be in the standby zone. The determination of whether or not to continue (step S72).

  Then, after the air blowing operation is started in step S73, it is determined whether the indoor temperature detected by the indoor temperature sensor 21 and the indoor humidity detected by the indoor humidity sensor 22 are in the high humidity zone (step S74). If it is determined that the room temperature and the room humidity are not in the high humidity zone (step S74: NO), it is determined whether the room temperature and the room humidity are in the monitoring zone (step S75). If it is determined that the room temperature and the room humidity are not in the monitoring zone (step S75: NO), it is determined whether the room temperature and the room humidity are in the standby zone (step S76). If it is determined that the room temperature and the room humidity are not in the standby zone (step S76: NO), the room temperature and the room humidity are considered to be in the high temperature zone, and the cooling operation is started (step S77).

  If it is determined in step S74 that the room temperature and the room humidity are in the high humidity zone (step S74: YES), the dehumidifying operation is started (step S78).

  Then, after the dehumidifying operation is started, it is determined whether the indoor temperature detected by the indoor temperature sensor 21 and the indoor humidity detected by the indoor humidity sensor 22 are in the high humidity zone (step S79). If it is determined that the room temperature and the room humidity are in the high humidity zone (step S79: YES), the cooling operation is started because the humidity is not lowered by the dehumidifying operation (step S77). On the other hand, when it is determined that the room temperature and the room humidity are not in the high humidity zone (step S79: NO), the room humidity decreases and the room temperature and the room humidity change to the monitoring zone and the standby zone. The dehumidifying operation is stopped (step S80), and the process proceeds to step S73 to continue the blowing operation.

  On the other hand, if it is determined in step S75 that the room temperature and the room humidity are in the monitoring zone (step S75: YES), the process proceeds to step S73 to continue the air blowing operation.

  If it is determined in step S76 that the room temperature and the room humidity are in the standby zone (step S76: YES), the air blowing operation is stopped (step S81).

  Then, after the cooling operation is started in step S77, it is determined whether the cooling operation is in the thermo-off state based on the indoor temperature detected by the indoor temperature sensor 21 and the set temperature (step S82). In the air conditioner, when the cooling operation is at a set temperature of 28 ° C. and the room temperature becomes 27 ° C. or lower, the thermo-off state is established. Therefore, in step S82, it is determined whether the cooling operation is in the thermo-off state based on whether the indoor temperature is 27 ° C. or lower. Then, if it is determined that the thermo-off state is not set (step S 82: NO), the room temperature is higher than 27 ° C., so the process proceeds to step S 77 and the cooling operation is continued.

  On the other hand, when it is determined that the cooling operation is in the thermo-off state (step S82: YES), it is determined whether the indoor temperature detected by the indoor temperature sensor 21 has changed to a temperature higher than the set temperature in the thermo-off state ( Step S83). If it is determined that the indoor temperature has changed to a temperature higher than the set temperature (step S83: YES), the process proceeds to step S77 and the cooling operation is started. If it is determined that the indoor temperature has not changed to a temperature higher than the set temperature (step S83: NO), the thermo-off state is continued.

  When the thermo-off state is continued, it is determined whether a predetermined time has elapsed (step S84). If it is determined that the predetermined time has elapsed in the thermo-off state (step S84: YES), the cooling operation is stopped (step S85). In the air conditioner, the cooling operation is stopped after a predetermined time has elapsed in the thermo-off state, so that when the cooling operation is stopped, the cooling operation is immediately started even if the room temperature and the room humidity rise. It can prevent.

  On the other hand, when it is determined that the predetermined time has not elapsed in the thermo-off state (step S84: NO), the process proceeds to step S83, and the indoor temperature detected by the indoor temperature sensor 21 changes to a temperature higher than the set temperature Determine if you did.

<Features of the air conditioner of the present embodiment>
In the air conditioner 1 of the present embodiment, as in the air conditioner 1 of the first embodiment, when the room is in a state where the room temperature and the room humidity need to be reduced, the room temperature and the room humidity are reduced. The cooling operation is automatically started. Therefore, it is possible to prevent the user from becoming a heat stroke or the like because the room temperature and the room humidity can be prevented from continuing for a long time in a high state.

  Moreover, in the air conditioner 1 of the present embodiment, when the room temperature and the room humidity are in the high humidity zone, the room humidity can be reduced by starting the dehumidifying operation.

  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 indicated not by the description of the embodiments described above but by the claims, and further includes all modifications within the meaning and scope equivalent to the claims.

  For example, in the first to fifth embodiments described above, 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. May be started. In this case, the determination diagram shown in FIG. 12 is used as the determination diagram for starting the forced operation. In the determination diagram of FIG. 12, 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 indoor temperature is in the high temperature zone, the cooling operation (forced operation) is started. If the indoor temperature is in the monitoring zone, perform a ventilation operation. When the room temperature is in the standby zone, neither cooling operation nor blowing operation is performed. The control in the forced operation mode of the air conditioner is performed based on the indoor temperature and the indoor humidity in the first to fifth embodiments, but differs in that it is performed based on the indoor temperature. The fifth embodiment is carried out in the same manner as the control shown in FIGS. 5 to 7 and 9 and 11 of the fifth embodiment.

  In the first to fifth embodiments described above, although the forced operation is automatically started based on the room temperature and the room humidity in the forced operation mode, the forced operation is automatically performed based on the indoor humidity in the forced operation mode. May be started. And control in the forced operation mode of the air conditioner differs in that it is performed based on indoor humidity in what is performed based on indoor temperature and indoor humidity in the first to fifth embodiments, but the others It is performed in the same manner as the control shown in FIGS. 5 to 7 and 9 and 11 of the first to fifth embodiments.

  Further, in the above-described first to fifth embodiments, in the forced operation mode, it may be informed that the forced operation is to be started before the forced operation is started.

  In the first to fifth embodiments described above, the air conditioner has the outside air temperature detection means for detecting the outside air temperature, and the outside air temperature detected by the outside air temperature detection means is predetermined in the forced operation mode. The forced operation may not be started when the temperature is lower than the ambient temperature.

  In the first to fifth embodiments described above, in the forced operation mode, the forced operation is started based on the indoor temperature and the indoor humidity detected by the indoor temperature sensor and the indoor humidity sensor attached to the indoor unit. The forced operation may be started based on the indoor temperature and the indoor humidity detected by the indoor temperature sensor and the indoor humidity sensor attached to the controller.

  In the first to fifth embodiments described above, in the forced operation mode, the air blowing operation when the room temperature and the room humidity are in the monitoring zone, the dehumidifying operation when the room temperature and the room humidity are in the high humidity zone, and the user In the automatic operation when the controller selects the automatic operation with the controller and performs the operation start operation, the air volume is lower than the air volume of the cooling operation, and the upper and lower flaps are arranged near the upper end of the movable range The air volume and the blowing direction can be changed.

  Moreover, in the above-described first to fifth embodiments, in the forced operation mode, the user can select automatic (automatic operation) with the controller 30 and perform only the operation start operation of the automatic operation, but the air blowing ( An operation start operation such as air blowing operation) or dehumidification (dehumidification operation) may be performed.

  By using the present invention, it is possible to start forced operation to lower the room temperature at the time of operation stop.
