The fan 5 is provided in the air passage connecting the air inlet 3 and the air outlet 4, the air 5 is sucked into the air, the air is blown into the room, the motor 6 that drives the fan 5, and the air outlet direction from the air outlet 4. The louver 7 to be changed, the stepping motor 8a as the louver motor 8 for driving the louver 7, the installation location specifying means 9 for specifying whether the place where the blower body 1 is installed is a wall surface or a ceiling surface, and the louver 7 The louver closing detection means 10 for detecting the closing is provided, and the installation location specifying means 9 is installed on either the wall surface or the ceiling surface based on the driving torque when the stepping motor 8a operates the louver 7. It is configured to identify. As the fan 5, for example, a cross flow fan having a fan having a relatively small diameter and a long side and having a quiet laminar flow with a width of the fan length and having a low static pressure and a large air volume is used. The louver closing detection means 10 only needs to be able to detect that the louver 7 is closed. For example, the louver closing detection means 10 has a contact switch 11 (not shown) and contacts the contact when the louver 7 is in the closed position. The switch is turned on.

  The rotation shaft 12 is provided on both sides of the louver 7 so as to be shifted from the center of gravity of the louver 7, so that the rotation shaft 12 is provided at a position different from the extension of the center of gravity of the louver 7. 12 is connected to the stepping motor 8a, and the louver 7 is rotated by rotationally driving the stepping motor 8a.

  Further, the front surface of the blower main body 1 is provided with a receiving means 15 for receiving a signal transmitted from the transmission means 14 of the remote control means 13 (hereinafter referred to as remote control 13a) capable of remotely operating the blower main body 1, For example, a buzzer is provided as a notification unit 16 that notifies the reception unit 15 of reception. The remote controller 13a only needs to be able to be remotely controlled, and includes, for example, an infrared remote controller. The transmission unit 14 may be any transmission unit such as an infrared LED. The receiving unit 15 may be any receiving unit such as an infrared light receiving element. As the notification means 16, it is only necessary to be able to notify, and not only a buzzer but also voice guidance may be used.

  The remote controller 13a is provided with a plurality of switches and display means 17 for displaying the operation state, etc. As these switches, there are an operation switch 18 for operating or stopping the blower, a mode switch 19 for switching the operation mode, An air flow switch 20 that can switch the air flow of the fan 5 between strong and weak, a wind direction adjusting switch 21 that adjusts the air direction by changing the angle of the louver 7, and a wind direction automatic switch 22 that reciprocates the louver 7 within a predetermined range. ing. The wind direction adjustment switch 21 includes an up switch 21a that increases the louver angle and a down switch 21b that decreases the louver angle.

  The operation mode includes a clothes drying mode for drying clothes, a cool air mode for obtaining a cool breeze with the wind blown from the air outlet 4, and an air current mode for circulating indoor air.

  The control device 23 includes a CPU such as a microcomputer and various interfaces (not shown) therein. When the receiving unit 15 receives a signal from the remote controller 13a, the CPU performs each interface based on the received signal. The motor 6, the stepping motor 8 a as the louver motor 8, and the notification means 16 are controlled.

  A method for specifying the installation location of the blower main body 1 by the installation location specifying means 9 will be described.

  Since the rotation shaft 12 is located at a position different from the extension of the center of gravity of the louver 7, when the louver 7 is in the same state, the rotation shaft 12 of the louver 7 is applied to the direction of gravity when the louver 7 is in the same state. The moments are different. That is, since the moment applied to the rotating shaft 12 is different when the louver 7 is closed, the driving torque when the louver 7 is operated is also different.

  As shown in FIG. 5, there is a characteristic that when the driving voltage of the stepping motor 8a is increased, the driving torque is also increased. The torque of the stepping motor 8a is controlled by changing the driving voltage of the stepping motor 8a, and the driving torque is determined from the driving voltage. Estimate the installation location.

  With the louver 7 closed and the contact switch 11 turned on, the control device 23 gradually increases the drive voltage of the stepping motor 8a. If the drive voltage when the contact switch 11 is turned off and the louver 7 starts to open is less than V1 defined in advance, the installation location specifying means 9 specifies that the installation location is a ceiling surface, and is V1 or higher. If so, the installation location is specified as a wall surface.

  The installation location may be specified not only every time the operation is started, but only when the operation is performed for the first time after power is supplied to the blower.

  Next, the operation of the blower main body 1 will be described.

  When the operation switch 18 is operated and a signal for operation in the selected operation mode is transmitted from the remote controller 13a and the reception means 15 receives the signal, the control device 23 operates the notification means 16 to generate a buzzer sound and receives the signal. In addition, the stepping motor 8a is driven and the louver 7 is operated. When the louver 7 is moved to a predetermined position and the air outlet 4 is opened, the control device 23 drives the motor 6 to rotate at a high speed when it is strong, and rotates at a low speed when it is weak. Then, the fan 5 is operated.

  The selection of the operation mode is switched by operating the mode switch 19 during the operation. Each time the operation is performed, the operation mode is switched in the order of the clothing drying mode, the cool air mode, and the airflow mode. When the signal is transmitted from the remote controller 13a and received by the receiving means 15, the control device 23 operates the notifying means 16 to sound a buzzer sound to notify that the signal has been received.

  When the operation switch 18 is operated again, an operation stop signal is transmitted from the remote controller 13a, and when the receiving means 15 receives it, the control device 23 operates the notifying means 16 to sound a buzzer sound and notify that the signal has been received. At the same time, the fan 5 is stopped. For example, after about 3 seconds have passed since the rotation of the fan 5 stops, the louver 7 is operated and the air outlet 4 is closed. If the buzzer sound for operation stop is different from the buzzer sound for operation start, it is easy to distinguish the operation start from the operation stop. Further, when starting the operation next time, it is convenient to operate in the operation mode selected in the previous operation.

  The louver operation in each operation mode will be described with reference to FIGS.

  First, the louver operation in the clothes drying mode will be described.

  When the receiving means 15 receives the clothes drying mode signal and starts operation in the clothes drying mode, the louver 7 is based on the closed position when it is installed on the wall surface and the installation location is specified on the wall surface. Move to angle α2. Then, the louver 7 is operated slowly (for example, 0.5 degrees / second) and is operated to the angle α1, thereby blowing air to the clothing while changing the blowing direction. Thereafter, the louver 7 is reciprocated within a range of angles α1 to α2.

  When installed on the ceiling surface and the installation location is specified on the ceiling surface, if the louver 7 is operated at the operating angles α1, α2 in the case of wall surface installation and blown, the air will be biased upwardly from the clothing, By reciprocating in the range of angles β1 and β2 larger than the wall surface installation, and blowing down further than the wall surface installation, the whole clothing is blown.

  As described above, during operation in the clothes drying mode, depending on the installation location, the louver 7 is constantly reciprocated within the range of the angles α1 to α2 or the range of the angles β1 to β2 to blow the clothes while changing the blowing direction. Then, the air layer saturated with humidity on the surface of the laundry is peeled off and diffused to promote clothes drying.

  Next, the louver operation in the cool breeze mode will be described.

  When the receiving means 15 receives the signal of the cool breeze mode and the operation in the cool breeze mode is started, the louver 7 is installed on the wall surface, and when the installation location is specified on the wall surface, the louver 7 has an angle α3 based on the closed position. To the floor and blow down diagonally downward.

  When installed on the ceiling surface and the installation location is specified on the ceiling surface, if the louver 7 is moved to the angle α3 in the case of wall surface installation and blown, the air is biased toward the wall surface. Is moved to a larger angle β3, so that air is blown obliquely downward to the floor surface as in the case of wall surface installation.

  Next, the louver operation in the airflow mode will be described.

  When the receiving means 15 receives the airflow mode signal and the operation in the airflow mode is started, the louver 7 is installed on the wall surface, and when the installation location is specified on the wall surface, the louver 7 has an angle α4 with respect to the closed position. The air is blown in a substantially horizontal direction with respect to the floor surface.

  When installed on the ceiling surface and the installation location is specified on the ceiling surface, if the louver 7 is moved to the angle α4 in the case of wall surface installation and blown, the air is blown to the floor surface. By moving to β4, air is blown in a substantially horizontal direction with respect to the floor surface as in the case of wall surface installation.

  The operation for finely adjusting the blowing direction will be described by taking the clothes drying mode as an example.

  While operating in the clothes drying mode, press and hold the wind direction automatic switch 22 of the remote control 13a for a predetermined time (for example, about 3 seconds that can be distinguished from normal operation) to enter the wind direction adjustment mode, and send a signal for adjusting the wind direction at the lower limit angle. To do. When the receiving means 15 receives the signal for adjusting the wind direction at the lower limit angle, the control device 23 operates the notifying means 16 to sound a buzzer sound and informs that the signal has been received. Move to an angle. In this state, the lower limit angle of the reciprocating operation range can be finely adjusted by operating the down switch 21b of the wind direction adjusting switch 21, and the change angle per switch operation is about 5 degrees. The user finely adjusts the lower limit angle of the reciprocating operation range to an appropriate position while confirming the blowing direction.

  When the automatic wind direction switch 22 is operated after adjusting the lower limit angle to an appropriate position, the remote controller 13a transmits a wind direction adjustment signal of the upper limit angle, and when the receiving means 15 receives the wind direction adjustment signal of the upper limit angle, the louver 7 Is moved to the upper limit angle of the reciprocating motion range. The upper limit angle is adjusted in the same manner as the lower limit angle.

  When the wind direction automatic switch 22 is operated after the upper limit angle is adjusted to an appropriate position, the wind direction adjustment mode is canceled, and the remote control 13a transmits a signal for canceling the wind direction adjustment, and the receiving means 15 receives the signal to slightly adjust the blowing direction. Adjustment ends. Thereafter, the louver 7 reciprocates within the adjusted upper limit angle and lower limit angle.

  In this embodiment, the louver 7 is operated at the start of operation, then the fan 5 is operated, and when the operation is stopped, the fan 5 is stopped and then the louver 7 is closed. May be operated simultaneously.

  With the above-described configuration, the louver 7 changes the operating angle according to the installation location specified by the installation location specifying means 9 and blows air, so that the user can perform appropriate operations without changing the blowing direction according to the installation location. It can be blown out in the direction and is easy to use.

  Moreover, since the installation location specifying means 9 specifies whether the stepping motor 8a is installed on the wall surface or the ceiling surface from the driving torque when the louver 7 is operated, the installation location can be reliably specified. This can be realized at a low cost without adding new parts.

  Also, the rotational axis 12 of the louver 7 does not coincide with the center of gravity, that is, one of the rotary shafts 12 is made heavier, so the driving torque during operation of the louver 7 differs between the wall surface and the ceiling surface, and it can be installed easily and reliably The location can be specified.

  Further, since the driving torque is estimated from the characteristics of the driving voltage and the driving torque of the stepping motor 8a, the installation location can be specified reliably, and the cost can be reduced without adding new parts. .

  In addition, in the clothes drying mode, the ceiling surface installation blows more obliquely downward toward the floor surface than the wall surface installation, so the clothes can be efficiently blown regardless of the installation location, and the clothes are dried with energy saving. can do.

  In the cool breeze mode, both the wall surface installation and the ceiling surface installation blow air diagonally downward to the floor surface, so that the user is effective without changing the blowing direction according to the installation location. A cool breeze can be obtained.

  In addition, in the airflow mode, the air is blown in a substantially horizontal direction with respect to the floor surface in both the wall surface installation and the ceiling surface installation, so that the effect can be obtained without the user performing an operation to change the blowing direction according to the installation location. Thus, indoor air can be circulated.

  In addition, by operating the wind direction adjustment switch 21, the operating angle of the louver 7 can be changed and the blowing direction can be finely adjusted. For example, the positional relationship between the installation of the blower and the clothes is the preset positional relationship. When there is a difference, by finely adjusting the blowing direction, the user can adjust to the actual situation and can efficiently dry clothes, which is easy to use.

(Embodiment 2)
As shown in FIG. 9, when the driving speed of the stepping motor 8a is increased, the driving torque decreases. The torque of the stepping motor 8a is controlled by changing the driving speed of the stepping motor 8a, and the driving torque is determined from the driving speed. Is configured to identify the installation location.

  In addition, description is abbreviate | omitted about the structure similar to Embodiment 1. FIG.

  In a state where the louver 7 is closed and the contact switch 11 is ON, the control device 23 starts driving at the driving speed S0 at which the driving torque of the stepping motor 8a becomes substantially zero, and gradually decreases the driving speed. Go. If the drive speed when the contact switch 11 is turned OFF and the louver 7 starts to open is greater than or equal to S1 defined in advance, the installation location specifying means 9 specifies that the installation location is a ceiling surface, and less than S1. If so, the installation location is specified as a wall surface.

  With the above configuration, since the driving torque is estimated from the characteristics of the driving speed and driving torque of the stepping motor 8a, the installation location can be specified reliably, and the cost can be reduced without adding new parts. Can do.

(Embodiment 3)
As shown in FIG. 10, a storage unit 24 for storing the installation location specified by the installation location specifying unit 9 is provided, and the control device 23 stores the installation location specified by the installation location specifying unit 9 in the storage unit 24. The stored setting is read out.

  In addition, description is abbreviate | omitted about the structure similar to Embodiment 1. FIG.

  A method for setting the installation location of the blower main body 1 will be described.

  Setting the installation location by combining a plurality of switches of the remote controller 13a, for example, the mode switch 19 and the wind direction automatic switch 22 and simultaneously pressing for a predetermined time (for example, about 3 seconds that can be distinguished from simultaneous pressing due to an erroneous operation). As shown in FIG. 11, the display unit 17 displays that it is the setting mode.

  When the blower main body 1 is installed on the ceiling surface, for example, when the mode switch 19 and the up switch 21a of the wind direction adjusting switch 21 are combined and pressed simultaneously, the setting of the installation location on the remote controller 13a is set to the ceiling surface installation and displayed. The display of the ceiling surface installation is displayed on the means 17 and the setting signal for the ceiling surface installation is transmitted from the transmission means 14.

  When the receiving unit 15 receives the setting signal for installing the ceiling surface, the installation location specifying unit 9 specifies that the installation location is the ceiling surface and stores it in the storage unit 24. And the control apparatus 23 operates the alerting | reporting means 16, and sounds the buzzer sound "pi", and alert | reports that the installation place was specified on the ceiling surface.

  When installed on the wall surface, for example, when the mode switch 19 and the down switch 21b of the wind direction adjusting switch 21 are combined and pressed simultaneously, the setting of the installation location on the remote controller 13a is set to the wall surface installation, and the display means 17 displays the wall surface installation display. In addition, a setting signal for wall surface installation is transmitted from the transmission means 14.

  When the receiving means 15 receives the setting signal for wall surface installation, the installation location specifying means 9 specifies that the installation location is a wall surface and stores it in the storage means 24. And the control apparatus 23 operates the alerting | reporting means 16, and alert | reports that the installation place was specified to the wall surface by sounding the buzzer sound "pipi" unlike the ceiling surface installation.

  When the remote controller 13a is in a mode other than the installation location setting mode, for example, when transmitting a signal such as driving or stopping, the remote controller 13a simultaneously transmits the signal of the installation location set in the remote controller 13a. The operation when the stored installation location settings are different will be described.

  For example, the air blower is installed on the ceiling surface, and the ceiling surface installation is set in both the remote controller 13a and the storage means 24. However, if the setting of the remote controller 13a is initialized by replacing the battery mounted on the remote controller 13a and the setting of the installation location is changed to the wall surface setting, the remote controller 13a transmits a signal such as driving or stopping. The signal of the installation location set in the remote controller 13a that is transmitted at the same time is transmitted by wall installation. When the receiving means 15 receives this wall surface setting signal, it differs from the setting of the storage means 24. Therefore, the control device 23 operates the notifying means 16 to emit a buzzer sound, and the setting of the remote control 13a and the setting of the storage means 24 are different. Notify that there is.

  Further, the control unit invalidates the wall surface installation signal received by the reception unit 15 and operates the louver 7 at the ceiling surface installation operation angle based on the setting of the storage unit 24.

  With the above configuration, the remote controller 13a is operated to set and transmit the installation location, and the reception unit 15 receives the setting signal to identify the installation location, so that the installation location can be easily and reliably set. This can be realized at a low cost without adding new parts.

  In addition, since the installation location is set by operating a combination of a plurality of predetermined switches on the remote controller 13a, the installation state can be easily set, and the setting is inadvertently changed due to an erroneous operation by the user. Can be prevented.

  Moreover, since the alerting | reporting means 16 alert | reports that the installation location was specified with the buzzer sound, it can recognize easily that the installation location was set.

  Further, since the buzzer sounds depending on the setting of the installation location, it is possible to easily recognize whether the installation location is specified on the wall surface or the ceiling surface, and the installation location and the blower set by the remote controller 13a are specified. It can be easily confirmed that the installation locations match.

  In addition, after setting the installation location, if the installation location signal set in the remote controller 13 a received by the receiving unit 15 is different from the setting of the installation location stored in the storage unit 24, it is stored in the storage unit 24. Since the louver 7 is operated based on the setting, the louver 7 can be reliably operated according to the installation location even when the setting of the remote controller 13a is changed unintentionally.

  Further, since the notification means 16 notifies the user that the setting of the remote controller 13a is different from the setting of the storage means 24 with a buzzer sound, the user easily recognizes that the setting of the remote controller 13a is different from the setting of the blower. be able to.
