  In the ceiling-suspended air conditioner described in the above-mentioned patent document, although not shown, generally, a downward outlet is disposed on the lower surface of the ceiling-suspended air conditioner. In addition, the conventional interior has a double ceiling structure in which the space for piping, wiring, etc. of the ceiling is partitioned by a board or the like with respect to the ceiling of the building itself. The number of cases where double ceilings are not provided is increasing. When it is a double ceiling, the air outlet of the ceiling-suspended air conditioner is exposed in the living space, but the space above it is in the double ceiling and is not included in the living space. However, if it is no longer a double ceiling, it will be decorated like a skeleton ceiling construction that directly includes the ceiling of the building in the living space, so that the space above the outlet of the ceiling-suspended air conditioner is included in the living space An environment has been generated. In such a case, air stays easily in the space above the outlet of the ceiling-suspended air conditioner. As a result, the heat discharged from the ceiling-suspended air conditioner also tends to accumulate in the space.

  As a result of intensive studies on the above problems, the present inventors have come up with the following content.

  That is, the 1st form of this indication provides a fan device provided with a fan and an attaching machine which attaches the fan to the ceiling suspension type air conditioner above the blower opening of the ceiling suspension type air conditioner.

  By installing the fan device in the ceiling-suspended air conditioner, the retention of air in the space above the air outlet of the ceiling-suspended air conditioner is reduced, and the accumulation of warm heat (warm air) in this space is also reduced. .

  A second form of the present disclosure provides a fan device according to the first form, further comprising a receiver that receives a signal from an external device, and a controller that controls the operation of the fan based on the signal.

  With this configuration, the fan device can be appropriately controlled in consideration of a signal from an external device.

  A third aspect of the present disclosure provides a fan device according to the second aspect, wherein the receiver is a receiver that receives an ON / OFF signal of the operation of the fan.

  With this configuration, the fan device can be appropriately controlled based on an external ON / OFF signal.

  A fourth form of the present disclosure provides a fan device according to the second form, wherein the receiver is a receiver that receives a signal related to an ON / OFF state of the ceiling-suspended air conditioner.

  With this configuration, the fan device can be appropriately controlled according to the ON / OFF state of the ceiling-suspended air conditioner.

  According to a fifth form of the present disclosure, in the fourth form, the control unit operates the fan when the receiver receives a signal indicating that the ceiling-suspended air conditioner is in an ON state, and the receiver Provided is a fan device that stops the operation of the fan when a signal indicating that the ceiling-suspended air conditioner is in an OFF state is received.

  When the ceiling-suspended air conditioner is in an ON operation, a flow may not be formed in the space above the blower opening of the ceiling-suspended air conditioner, and a heat bias may occur in which warm heat accumulates.

  Here, according to the fifth embodiment, the air convection including the above-described space is generated, and the heat bias that warm heat is accumulated in the space is reduced.

  According to a sixth aspect of the present disclosure, in the fourth aspect, the control unit operates the fan when the receiver receives a signal indicating that the ceiling-suspended air conditioner is in an OFF state, and the receiver Provided is a fan device that stops the operation of the fan when a signal indicating that the ceiling-suspended air conditioner is in an ON state is received.

  When the ceiling-suspended air conditioner is turned off, a flow may not be formed in the space above the blower opening of the ceiling-suspended air conditioner, and a heat bias may occur in which warm heat accumulates. In particular, when a ceiling-suspended air conditioner that is different from the ceiling-suspended air conditioner that is turned off is in the ON state, the ceiling suspended air-conditioner that is in the ON state is affected by the airflow created by the ceiling-suspended air conditioner that is in the ON state. Air conditioners do not generate airflow. Then, heat may accumulate in the space above the air outlet of the ceiling-suspended air conditioner in the OFF state.

  Here, according to the sixth embodiment, air convection including the space described above is generated, and the heat bias that warm heat accumulates in the space is alleviated.

  7th form of this indication provides the fan apparatus which is a receiver which receives the signal regarding the operation mode currently performed in the said ceiling-suspended air conditioner in the said 2nd form.

  With this configuration, the fan device can be appropriately controlled according to the operation mode of the ceiling-suspended air conditioner.

  When the ceiling-suspended air conditioner is in the heating mode, a state in which the heat is discharged from the ceiling-suspended air conditioner and the heat accumulates easily occurs. Here, according to the eighth embodiment, when the ceiling-suspended air conditioner is set to the heating mode, the fan device is turned on / off in conjunction with the ON / OFF state of the ceiling-suspended air conditioner. . On the other hand, in the cooling mode, the state in which the cool air flows downward (region where people are present) within the set temperature range is not a particularly problematic environmental state. Therefore, when the ceiling-suspended air conditioner is set to the cooling mode, the fan device is not operated regardless of the ON / OFF state of the air conditioner. With such operation control, a fan operation is performed to alleviate the thermal bias when the thermal bias in the space above the air outlet of the ceiling-suspended air conditioner becomes a problem.

Provided is a fan device that stops the operation of the fan when it receives a signal indicating that it is in the second air volume mode.

  In the first air volume mode with a small air volume, since the air flow created by the ceiling-suspended air conditioner is small, a bias in temperature tends to occur in the space above the air outlet of the ceiling-suspended air conditioner. Here, according to the ninth embodiment, the fan device is turned on. Thereby, the convection of air including the space is generated, and the heat bias that heat is accumulated in the space is alleviated. On the other hand, in the second air volume mode in which the air volume is large, the air flow created by the ceiling-suspended air conditioner is large, so that the temperature bias generated in the space is relatively small.

A second wind direction mode having a large slope, and the controller operates the fan when the receiver receives a signal indicating that the ceiling-suspended air conditioner is in the first wind direction mode, and receives the signal. Provided is a fan device that stops the operation of the fan when the unit receives a signal indicating that the ceiling-suspended air conditioner is in the second wind direction mode.

  When the operation mode of the ceiling-suspended air conditioner is the first wind direction mode in which the wind direction of the ceiling-suspended air conditioner has a small downward slope, the air flow created by the ceiling-suspended air conditioner is higher in the room (people Therefore, air convection is less likely to occur in the entire room, and thermal bias is likely to occur in the space above the air vent of the ceiling-suspended air conditioner. Here, according to the tenth embodiment, the fan device is turned on. Thereby, the convection of air including the space is generated, and the heat bias that heat is accumulated in the space is alleviated. On the other hand, when the ceiling-suspended air conditioner is in the second wind direction mode in which the wind direction of the ceiling-suspended air conditioner is large, the air flow created by the ceiling-suspended air conditioner is directed downward in the room. Is likely to occur, and the bias of the heat generated in the space is relatively small. Here, according to the tenth embodiment, the fan device is turned off. It is possible to suppress the occurrence of convection of air in the building including the space more than necessary. By such operation control, the bias of the heat generated in the space is efficiently reduced.

  An eleventh aspect of the present disclosure provides the fan device according to the second aspect, wherein the receiver is a receiver that receives a signal related to a temperature of air sucked by the ceiling-suspended air conditioner.

  With this configuration, the fan device can be appropriately controlled according to the temperature of the air sucked into the ceiling-suspended air conditioner.

  A twelfth aspect of the present disclosure provides the fan apparatus according to the second aspect, wherein the receiver is a receiver that receives a signal related to a use environment of the fan apparatus.

  With this configuration, the fan device can be appropriately controlled according to the usage environment of the fan device.

  According to a thirteenth aspect of the present disclosure, in the twelfth aspect, the use environment is humidity, and the controller operates the fan when receiving a signal indicating that the receiver is high in humidity. Provided is a fan device that stops the operation of the fan when the receiver receives a signal indicating that the humidity is low.

  When the humidity of the fan device is high, the humidity in the air tends to accumulate in the space above, particularly above the air outlet of the ceiling-suspended air conditioner. Here, according to the thirteenth embodiment, the fan device is turned on. Thereby, an air flow is generated in the space, and the occurrence of condensation and mold near the ceiling is reduced. On the other hand, when the humidity of the fan device is low, according to the thirteenth embodiment, the fan device is turned off. This suppresses the fan device from operating more than necessary. By such operation control, the accumulation of moisture in the space is efficiently mitigated.

  A fourteenth aspect of the present disclosure is the fan apparatus according to the twelfth aspect, wherein the use environment is an ON / OFF state of another ceiling-suspended air conditioner that is different from the ceiling-suspended air conditioner in which the fan apparatus is installed. I will provide a.

  With this configuration, the fan device can be appropriately controlled according to the ON / OFF state of another ceiling-suspended air conditioner that is different from the ceiling-suspended air conditioner in which the fan device is installed.

(Third embodiment)
A fan device 100 according to a third embodiment will be described. Since the fan device 100 of the present embodiment has the same configuration as the fan device 100 of the first embodiment, detailed description thereof is omitted.

[Operation]
The operation of the fan device 100 of this embodiment will be described.

  FIG. 9 is a flowchart illustrating an example of the operation of the fan device 100 according to the third embodiment.

  As shown in FIG. 9, first, a signal related to the operation mode of the ceiling-suspended air conditioner 200 is received from an external device via the receiver 2 (step S31). In this example, the operation mode includes a heating mode in which the ceiling-suspended air conditioner 200 performs a heating operation and a cooling mode in which the ceiling-suspended air conditioner 200 performs a cooling operation. Next, the controller 3 determines whether the ceiling-suspended air conditioner 200 is in the heating mode based on the signal received by the receiver 2 (step S32). When the operation mode of the ceiling-suspended air conditioner 200 is the heating mode (Yes in step S32), the controller 3 operates the fan device 100 according to the ON / OFF state of the ceiling-suspended air conditioner (step S33). Specifically, the control of the fan device 100 shown in FIG. 7 or FIG. 8 is executed. When the operation mode of the ceiling-suspended air conditioner 200 is not the heating mode (No in step S32), it is determined whether or not the operation mode of the ceiling-suspended air conditioner 200 is the cooling mode (step S34). When the operation mode of the ceiling-suspended air conditioner 200 is the cooling mode (Yes in step S34), the controller 3 stops the operation of the fan device 100 (step S35). When the operation mode of the ceiling-suspended air conditioner 200 is not the cooling mode (No in step S34), the control flow of the fan device 100 of the present embodiment is ended (end).

  When the ceiling-suspended air conditioner 200 is in the heating mode, a state in which the heat is discharged from the ceiling-suspended air conditioner 200 and the heat accumulates easily occurs.

  On the other hand, in the cooling mode, the state in which the cool air flows downward (region where people are present) within the set temperature range is not a particularly problematic environmental state. Therefore, when the ceiling-suspended air conditioner is set to the cooling mode, the fan device is not operated regardless of the ON / OFF state of the air conditioner. By such operation control, operating the fan apparatus 100 more than necessary is suppressed, and energy consumption is reduced.

  That is, due to the above operation of the fan device 100, the temperature bias in the space above the air blowing port 7 of the ceiling-suspended air conditioner is efficiently reduced.

(Fourth embodiment)
A fan device 100 according to a fourth embodiment will be described. Since the fan device 100 of the present embodiment has the same configuration as the fan device 100 of the first embodiment, detailed description thereof is omitted.

[Operation]
The operation of the fan device 100 of this embodiment will be described.

  FIG. 10 is a flowchart illustrating an example of the operation of the fan device 100 according to the fourth embodiment.

  As shown in FIG. 10, first, a signal related to the operation mode of the ceiling-suspended air conditioner 200 is received from an external device via the receiver 2 (step S41). In this example, the operation mode includes a first air volume mode in which the air volume of the ceiling-suspended air conditioner 200 is small and a second air volume mode in which the air volume of the ceiling-suspended air conditioner 200 is large. Next, the controller 3 determines whether or not the operation mode of the ceiling-suspended air conditioner 200 is the first air volume mode based on the signal received by the receiver 2 (step S42). When the operation mode of the ceiling-suspended air conditioner 200 is the first air volume mode (Yes in step S42), the controller 3 operates the fan device 100 (step S43). When the operation mode of the ceiling-suspended air conditioner 200 is not the first air volume mode (No in step S42), the controller 3 determines whether the operation mode of the ceiling-suspended air conditioner 200 is the second air volume mode. Determination is made (step S44). When the operation mode of the ceiling-suspended air conditioner 200 is the second air volume mode, the operation of the fan device 100 is stopped (step S45). When the operation mode of the ceiling-suspended air conditioner 200 is not the second air volume mode (No in step S44), the control flow of this embodiment is ended (end).

  In the first air volume mode in which the air volume is small, the air flow created by the ceiling-suspended air conditioner 200 is small, and thus a bias in temperature is likely to occur in the space above the air outlet 7 of the ceiling-suspended air conditioner. Here, according to the above operation, the fan device 100 is turned on. Thereby, the convection of air including the space is generated, and the heat bias that heat is accumulated in the space is alleviated. On the other hand, in the second operation mode in which the air volume is large, the air flow created by the ceiling-suspended air conditioner 200 is large, and thus the temperature bias generated in the space is relatively small. Here, according to the above operation, the fan device is turned off. Thereby, it can suppress that the convection of the air in a building including the said space more than necessary generate | occur | produces. By such operation control, the bias of the heat generated in the space is efficiently reduced.

(Fifth embodiment)
A fan device 100 according to a fifth embodiment will be described. Since the fan device 100 of the present embodiment has the same configuration as the fan device 100 of the first embodiment, detailed description thereof is omitted.

[Operation]
The operation of the fan device 100 of this embodiment will be described.

  FIG. 11 is a flowchart illustrating an example of the operation of the fan device 100 according to the fifth embodiment.

  As shown in FIG. 11, first, a signal related to the operation mode of the ceiling-suspended air conditioner 200 is received from an external device via the receiver 2 (step S51). In this example, the operation mode includes a first wind direction mode in which the wind direction of the ceiling-suspended air conditioner 200 has a small downward slope and a second wind direction mode in which the wind direction of the ceiling-suspended air conditioner 200 has a large downward slope. . Next, the controller 3 determines whether or not the ceiling-suspended air conditioner 200 is in the first wind direction mode based on the signal received by the receiver 2 (step S52). When the operation mode of the ceiling-suspended air conditioner 200 is the first wind direction mode (Yes in step S52), the controller 3 operates the fan device 100 (step S53). When the operation mode of the ceiling-suspended air conditioner 200 is not the first wind direction mode (No in step S52), it is determined whether the operation mode of the ceiling-suspended air conditioner 200 is the second wind direction mode (step S54). ). When the operation mode of the ceiling-suspended air conditioner 200 is the second wind direction mode (Yes in step S54), the controller 3 stops the operation of the fan device 100 (step S55). When the operation mode of the ceiling-suspended air conditioner 200 is not the second wind direction mode (No in step S54), the control flow of the fan device 100 of this embodiment is ended (end).

  When the operation mode of the ceiling-suspended air conditioner 200 is the first wind direction mode in which the wind direction of the ceiling-suspended air conditioner 200 is small in the downward direction, the air flow generated by the ceiling-suspended air conditioner 200 is higher in the room. Since it occurs in a relatively upper part of the area where people are present, air convection is unlikely to occur in the entire room, and an uneven temperature is generated in the space above the air outlet 7 of the ceiling-suspended air conditioner 200. Cheap. Here, according to the above operation, the fan device 100 is turned on. Thereby, the convection of air including the space is generated, and the heat bias that heat is accumulated in the space is alleviated. On the other hand, when the ceiling-suspended air conditioner 200 is in the second wind direction mode in which the wind direction of the ceiling-suspended air conditioner 200 is large in the downward direction, the air flow created by the ceiling-suspended air conditioner 200 is directed downward in the room. Convection is likely to occur, and the temperature bias generated in the space is relatively small. Here, according to the above operation, the fan device is turned off. Thereby, it can suppress that the convection of the air in a building including the said space more than necessary generate | occur | produces. By such operation control, the bias of the heat generated in the space is efficiently reduced.

  As for the wind direction, the airflow does not necessarily occur only in the direction intended by the equipment, and the airflow often changes depending on the building structure, etc., so the control method depends on the operating environment, operating conditions, and thermal environment. It may be appropriate to set (sometimes the control method opposite to the above operation). In preparation for such a case, the fan device 100 may be configured to change the logic of control for turning on / off the operation.

(Sixth embodiment)
A fan device 100 according to a sixth embodiment will be described. Since the fan device 100 of the present embodiment has the same configuration as the fan device 100 of the first embodiment, detailed description thereof is omitted.

[Operation]
The operation of the fan device 100 of this embodiment will be described.

  FIG. 12 is a flowchart illustrating an example of the operation of the fan device 100 according to the sixth embodiment.

  As shown in FIG. 12, first, a signal related to the temperature of the ceiling-suspended air conditioner 200 is received from an external device via the receiver 2 (step S61). Next, the controller 3 determines whether or not the temperature of the air sucked into the ceiling-suspended air conditioner 200 is equal to or higher than the threshold value Tth based on the signal received by the receiver 2 (step S62). When the temperature of the air sucked into ceiling-suspended air conditioner 200 is equal to or higher than threshold value Tth, controller 3 operates fan device 100 (step S63). When the temperature of the air sucked into ceiling-suspended air conditioner 200 is lower than threshold value Tth (No in step S62), controller 3 stops the operation of fan device 100 (step S64).

  When the temperature of the air sucked into the ceiling-suspended air conditioner 200 is high, it is presumed that the temperature bias in the space above the air blowing port 7 of the ceiling-suspended air conditioner 200 is large. Here, the unevenness of the heat in the space is alleviated by the above operation. Moreover, when the temperature of the air sucked by the ceiling-suspended air conditioner 200 is low, it is presumed that the temperature deviation in the space is relatively small. Here, the operation described above can suppress the occurrence of convection of air in the building including the space more than necessary. By such operation control, the bias of the heat generated in the space is efficiently reduced.

  In the above operation example, as the temperature of the air sucked into the ceiling-suspended air conditioner 200, for example, the temperature near the suction port (not shown) of the ceiling-suspended air conditioner 200 may be used. It is not limited to. Any form may be used as long as the temperature of the air sucked into the ceiling-suspended air conditioner 200 can be detected.

(Seventh embodiment)
A fan device 100 according to a seventh embodiment will be described. Since the fan device 100 of the present embodiment has the same configuration as the fan device 100 of the first embodiment, detailed description thereof is omitted.

[Operation]
The operation of the fan device 100 of this embodiment will be described.

  FIG. 13 is a flowchart illustrating an example of the operation of the fan device 100 according to the seventh embodiment.

  As shown in FIG. 13, first, a signal related to the usage environment of the fan device 100 is received from an external device via the receiver 2 (step S71). In this example, the usage environment of the fan device 100 is humidity. Next, the controller 3 determines whether or not the humidity is equal to or higher than the threshold value Hth based on the humidity-related signal received by the receiver 2 (step S72). When the humidity is equal to or higher than the threshold value Hth, the controller 3 operates the fan device 100 (step S73). If the humidity is less than the threshold value Hth (No in step S72), the controller 3 stops the operation of the fan device 100 (step S74).

  When the humidity of the fan device 100 is high, the humidity in the air tends to accumulate in the space above, in particular, the space above the air outlet of the ceiling-suspended air conditioner. Here, according to the above operation, the fan device 100 is turned on. Thereby, an air flow is generated in the space, and the occurrence of condensation and mold near the ceiling is reduced. On the other hand, when the humidity of the fan device 100 is low, the fan device is turned off according to the above operation. Thereby, operating the fan apparatus 100 more than necessary is suppressed. By such operation control, the accumulation of moisture in the space is efficiently mitigated.

  The humidity is not limited to the humidity inside the building, but it can also be judged by information related to the humidity inside the building, such as humidity as weather data, humidity outside the building, etc., and relative humidity, absolute humidity, etc. Any index indicating humidity in the air can be used.

(Modification)
Although the present disclosure has been described based on the above-described embodiment, the present disclosure is not limited to the above-described embodiment and the above-described modified examples. The following may be used.

  (1) As the usage environment of the fan device 100, an ON / OFF state of another ceiling-suspended air conditioner different from the ceiling-suspended air conditioner in which the fan device is installed may be used. Thereby, a fan apparatus can be suitably controlled according to the ON / OFF state of another ceiling suspension type air conditioner different from the ceiling suspension type air conditioner in which the fan apparatus is installed.

  A specific example is as follows. For example, when the operation mode of the ceiling-suspended air conditioner 200 adjacent to the ceiling-suspended air conditioner 200 provided with the fan device 100 is the heating mode and the wind direction is the horizontal wind direction, the fan device 100 is provided. It is assumed that there is a tendency for heat to accumulate in a space above the air blowing port 7 of the ceiling-suspended air conditioner 200 that is provided. Here, if it is determined from the signal relating to the operation of the adjacent ceiling-suspended air conditioner 200 received by the receiver 2 that the operation mode is the heating mode, the wind direction is the horizontal wind direction, and the ON state, the fan device 100 is turned on. Make it work. By such operation control, the uneven temperature of the space can be efficiently eliminated.

  (2) Other device information and sensor information notified from the energy management system may be used. In addition, since the determination of the operation state of surrounding devices is complicated and complicated, the necessity of turning on / off the operation of the corresponding fan device 100 in the energy management system is determined and the result is received, You may use as a judgment material for ON / OFF control of operation | movement of the apparatus 100. FIG.

  (3) The receiver 2 may not receive the signal related to the usage environment of the fan device 100. For example, the fan device 100 may include a detector that detects its own usage environment, and the controller 3 may control the operation of the fan 1 based on the usage environment of the fan device 100 detected by this detector. Examples of the detector include a detector that detects humidity, temperature, and the like.

  The present disclosure is useful as a fan device and a ceiling-suspended air conditioner that are improved in terms of air conditioning as compared with the related art.
