In addition, not only the monogram 50 but also a permanent magnet equivalent to the monogram magnets 51A and 51B may be provided on the back side of the member forming the front surface of the fan guard 23.

  FIG. 12 shows a main electric configuration of the electric fan. In the figure, a microcomputer 64 as a control unit built in the remote controller 2 operates by receiving power supply from a power supply unit 71 including batteries such as batteries 65A and 65B. The switch contacts corresponding to the buttons 58A to 58H of 58, the external connection means 72 including a USB terminal enabling connection to the Internet and the like, and the power supply means 71 for detecting the remaining amount of the batteries 65A and 65B. The incorporated battery remaining amount detecting unit 73 is electrically connected. An output port of the microcomputer 64 is electrically connected to a remote control transmitting unit 63 serving as infrared LEDs 63A and 63B and a wireless unit, and a remote control display unit 61 including an LCD 59 and a backlight 60.

  The external connection means 72 allows the remote controller 2 to be connected to the Internet, which is an external communication means, instead of being a stand-alone device. It has a function of controlling the unit 13. Further, the battery remaining amount detection unit 73 may include, for example, a voltage detection circuit that detects a voltage between both ends of the batteries 65A and 65B, and may detect the remaining amounts of the batteries 65A and 65B based on a detection result from the voltage detection circuit.

  The microcomputer 64 of the remote controller 2 includes, as software functions, a transmission controller 75 that mainly controls the remote controller transmitter 63 and a display controller 76 that controls the operation of the remote controller display 61. The remote controller 2 includes a timer (not shown) as a counter that counts time and a period. In addition, the operation of the fan main body 1 that can be set by operating the remote control operation unit 58 includes, for example, an operation state of the fan main body 1. And the amount of air from the blower 13, the vertical and horizontal swinging ranges of the blower 13 by the swinging device 14, the type of blown air (continuous or random) from the blower 13, and the operation of the fan body 1. A setting content storage unit 77 for storing and holding settings such as a time for automatically turning on the timer (timer on time) and a time for automatically turning off the operation of the electric fan body 1 (timer off time) is provided as a memory serving as a storage unit. 78 in a partial area.

  The transmission control unit 75 controls the remote control transmission unit 63 so that an infrared signal including a unique code is transmitted each time an operation signal is received from any of the buttons 58A to 58H of the remote control operation unit 58. is there. In addition, when the transmission control unit 75 of the present embodiment receives an operation signal from the buttons 58A to 58G that can set the operation of the above-described electric fan main unit 1 among the buttons 58A to 58H of the remote control operation unit 58, the transmission control unit 75 performs the operation. While the setting contents after the change corresponding to the pressed buttons 58A to 58G are overwritten and updated in the setting content storage unit 77, especially when an operation signal from the transfer button 58H is received, the setting content storage unit 84 described later of the electric fan body 1 All stored settings are cleared, and then all settings stored in the settings storage 77 of the remote controller 2 are re-stored in the settings storage 84 of the fan body. It has a function of transmitting an infrared signal for setting (resetting signal) from the remote control transmitting unit 63.

  The display control unit 76 causes the remote controller display unit 61 to display the changed setting content overwritten and updated in the setting content storage unit 77 described above. In particular, the display control unit 76 turns off the remote control display unit 61 after a certain period of time has elapsed after setting the operation of the electric fan main body 1 using the buttons 58A to 58G, and operates the remote control display unit 58 again when the remote control operation unit 58 is operated again. The section 61 has a function of controlling to continuously display the previous setting contents stored in the setting content storage section 77 or to display the initial state setting contents stored by default.

  Specifically, after any one of the buttons 58A to 58H of the remote control operation unit 58 is first operated until the predetermined period elapses after the remote control display unit 61 is turned off after a predetermined time, the setting content is stored. The previous settings stored in the section 77 are displayed on the remote control display section 61. On the other hand, after a predetermined time has elapsed after the remote control display 61 has been turned off after a certain period of time, for example, when using the electric fan in the next season, any of the buttons 58A to 58H of the remote control operation unit 58 When this is operated for the first time, the settings of the initial state stored at the time of product shipment are displayed on the remote control display unit 61. From there, when any of the buttons 58A to 58G is operated in the remote control operation unit 58, the changed setting contents reflecting the operation are overwritten and stored in the setting content storage unit 77, and the remote control display unit 61 Is displayed for a certain period of time after the change.

  Also, as in the present embodiment, when the remote control display unit 61 is configured by the LCD 59 with the backlight 60 that can be displayed by supplying power from the batteries 65A and 65B, when the remote control operation unit 58 is operated, the LCD 59 is set. After the contents are displayed, the backlight 60 is turned on for a certain period of time. When the remote control operation unit 58 is not operated, the backlight 60 is turned off. The display control unit 76 may be configured so that the backlight 60 is kept turned off unless the unit 58 is operated. In this case, while the backlight 60 is turned off, the setting contents may be continuously displayed on the LCD 59 so that the user can check the setting contents at hand, and the backlight 65 may be used to suppress the power consumption of the batteries 65A and 65B. The LCD 59 may be turned off together with the light 60.

  In addition, when the remaining amount of the batteries 65A and 65B detected by the battery remaining amount detecting unit 73 falls below a predetermined value, the display control unit 76 turns on the backlight 60 when operating the remote control operating unit 58. The LCD 59 has a function of displaying the above-described setting contents without turning off the light, or displaying the remaining amount of the batteries 65A and 65B in a level on, for example, a level display section 59C of the LCD 59.

  A light receiving section 68 for receiving an infrared signal from the remote controller 2 is electrically connected to an input port of the control section 69 provided in the base 11 of the electric fan body 1. The output port of the control unit 69 includes a DC fan motor 21 serving as a drive source of the blower unit 13, an operation lamp 17 indicating an operation state of the fan body 1, and a swing motor 79 incorporated in the swing device 14. Are respectively connected as loads of the fan body 1.

  The control unit 69 includes, as software functions of the microcomputer, an air blowing control unit 81 that mainly controls the operation of the DC fan motor 21, an operation lamp control unit 82 that controls the operation of the operation lamp 17, and a swing motor 79. And a swing control unit 83 for controlling the operation of the camera. The control unit 69 includes, for example, a timer unit (not shown) as a counter for counting time and time for timer operations such as an on timer and an off timer, and also includes the operation of the fan body 1 during operation. Even after the operation of the fan main body 1 is stopped, a setting content storage section 84 for storing and holding the above-described setting contents of the fan main body 1 is provided in a partial area of the memory 85 serving as a storage section.

  Next, the operation of the electric fan having the above configuration will be described based on the flowcharts of FIGS.

  FIG. 13 shows a control procedure of the remote controller 2 when the operation ON / OFF button 58A is operated. In FIG. 7, when the transmission control unit 75 of the remote controller 2 receives an operation signal associated with the operation of the operation ON / OFF button 58A in step S1, the transmission control unit 75 stores the setting stored in the setting content storage unit 77 in the next step S2. It is determined whether or not the current operation state of the electric fan body 1 is in operation. Here, the operation state of the fan main body 1 is determined based on the airflow level from the blower 13 (for example, 8 levels from 0 to 7. 0 is not blown, and the airflow increases as the number increases from 1; If the air volume is any one of the levels 1 to 7, the transmission control unit 75 of the remote controller 2 determines that the electric fan body 1 is in operation, and proceeds to the next step. In S3, the air volume level during the operation is overwritten and stored in the setting content storage unit 77 as the air volume level from the air blower 13. Further, in the next step S4, the operation state of the electric fan body 1 is overwritten and stored in the setting content storage unit 77, assuming that the airflow level is 0, that is, it is turned off.

  On the other hand, if the air volume is at the level of 0 in the above-described step S2, the transmission control unit 75 of the remote controller 2 determines that the electric fan body 1 is not in operation and is off, and in the next step S5, the setting contents The level of the air volume from the blower unit 13 stored in the storage unit 77 is overwritten and stored in the setting content storage unit 77 as the operating state of the electric fan body 1.

  Thereafter, the process proceeds to step S6, and the display control unit 76 causes the remote control display unit 61 to display the level of the air volume from the blower unit 13 stored in the setting content storage unit 77. At this time, in order to illuminate the LCD 59 from behind with the backlight 60 to improve the visibility of the remote control display unit 61, the remote control display unit 61 displays on the level display unit 59C of the LCD 59 a blower unit as the changed setting content. The backlight 60 is turned on for a certain period of time while the level of the airflow from 13 is displayed.

  Then, in the next step S7, the transmission control unit 75 of the remote control 2 causes the remote control transmission unit 63 to transmit an infrared signal including an operation on / off code for switching the operation of the electric fan body 1 from the remote control transmission unit 63. A series of operations ends in step S8.

  When the infrared signal reaches the light receiving section 68 of the electric fan main body 1, the electric fan main body 1 which has been in the off state is started to operate by the control section 69, and the operation lamp control section 82 turns on the operation lamp 17 from off to on. Is transmitted. Further, the blower control unit 81 performs control for supplying an appropriate drive signal to the DC fan motor 21 so that air is blown from the blower unit 13 at the airflow level stored and held in the setting content storage unit 84. Along with sending the signal, the swing control unit 83 also controls the swing motor 79 so that the blower unit 13 swings within the swing range stored and held in the setting content storage unit 84. And sending another control signal for supplying a suitable drive signal.

  On the other hand, if the infrared signal including the operation ON / OFF code reaches the light receiving section 68 while the electric fan body 1 is in operation, the operation of the electric fan body 1 is stopped by the control section 69, and the operation lamp is turned off. The control unit 82 switches the operation lamp 17 from on to off. In either case, when the control unit 69 receives the infrared signal including the operation on / off code from the remote control 2 by the light receiving unit 68, the control unit 69 controls the remote control 2 to match the setting contents of the fan main body 1 and the remote control 2. The same procedure as that in steps S2 to S5 is executed with the setting content storage unit 84.

  FIG. 14 shows a control procedure on the remote controller 2 side when the air volume UP button 58D is operated. In FIG. 7, when the transmission control unit 75 of the remote controller 2 receives an operation signal associated with the operation on the air volume UP button 58D in step S11, the current fan stored in the setting content storage unit 77 is stored in the next step S12. It is determined whether the operation state of the main body 1 is in operation. Since the operation state of the fan main body 1 is stored at the level of the air volume from the blower 13, if the air volume is any one of 1 to 7, the transmission control unit 75 of the remote controller 2 determines that the fan main body 1 is operating. Then, in the next step S13, the new air volume level obtained by adding 1 to the air volume level is set as the operating state of the electric fan body 1 and the air volume level from the air blower 13 as the setting content storage unit 77. Overwrite and store. However, here, the maximum level of the air volume is set to “7” in advance, so if the new air volume is larger than 7 which is the maximum level in the next step S14, this is set to 7 in step S15 and the process proceeds to step S16. If the new air volume is 7 or less in step S14, the process proceeds to step S16 without any change.

  On the other hand, if the operation state of the electric fan body 1 is stored as the level of the air volume 0 in step S12 described above, the operation state of the electric fan body 1 stored in the setting content storage unit 77 and the air volume from the air blowing unit 13 The level is set as the changed content, and the process proceeds to step S16.

  After that, in step S16, the display control section 76 causes the remote control display section 61 to display the level of the air volume from the blower section 13 stored in the setting content storage section 77. At this time, in order to improve the visibility of the remote control display unit 61, the remote control display unit 61 displays the level of the air volume from the blower unit 13 on the level display unit 59C of the LCD 59 as the changed setting content. Thus, the backlight 60 is turned on for a certain period of time.

  Then, in the next step S17, the transmission control unit 75 of the remote controller 2 transmits, from the remote control transmission unit 63, an infrared signal including an air volume UP code for increasing the level of the air volume set in the electric fan body 1 by one step. Then, a series of operations as the remote controller 2 is completed in step S18.

  When the infrared signal reaches the light receiving section 68 of the fan main body 1, if the fan main body 1 is in operation, the air volume of the blower 13 becomes one step stronger than before. When the light receiving section 68 receives the infrared signal including the air volume UP code from the remote controller 2, the control section 69 of the fan main body 1 performs step S 12 of the remote controller 2 to match the setting contents of the fan main body 1 and the remote controller 2. A procedure similar to S15 is executed between the setting content storage unit 84.

  FIG. 15 shows a control procedure on the remote control 2 side when the air volume DOWN button 58E is operated. In FIG. 7, when the transmission control unit 75 of the remote controller 2 receives an operation signal associated with the operation of the air volume DOWN button 58E in step S21, the current fan stored in the setting content storage unit 77 is stored in the next step S22. It is determined whether the operation state of the main body 1 is in operation. Since the operation state of the fan main body 1 is stored at the level of the air volume from the blower 13, if the air volume is any one of 1 to 7, the transmission control unit 75 of the remote controller 2 determines that the fan main body 1 is operating. In the next step S23, the new air volume level obtained by subtracting 1 from the air volume level is used as the operating state of the electric fan body 1 and the air volume level from the air blower 13 as the setting content storage unit 77. Overwrite and store. However, in this case, since the minimum level of the air volume at which the air blowing unit 13 performs the air blowing operation is set to “1” in advance, if the new air volume is smaller than 1 which is the maximum level in the next step S24, this is set to 1 in step S15. Then, if the new air volume is 1 or more in step S14, the process directly proceeds to step S26.

  On the other hand, in step S22 described above, if the operation state of the electric fan body 1 is stored as the level of the air volume 0, the operation state of the electric fan body 1 stored in the setting content storage unit 77 and the air volume from the air blowing unit 13 The level is set to the changed content as it is, and the process proceeds to step S26.

  After that, in step S26, the display control section 76 causes the remote control display section 61 to display the level of the air volume from the blower section 13 stored in the setting content storage section 77. At this time, in order to improve the visibility of the remote control display unit 61, the remote control display unit 61 displays the level of the air volume from the blower unit 13 on the level display unit 59C of the LCD 59 as the changed setting content. Thus, the backlight 60 is turned on for a certain period of time.

  Then, in the next step S27, the transmission control unit 75 of the remote controller 2 transmits, from the remote control transmission unit 63, an infrared signal including an air volume DOWN code for increasing the level of the air volume set in the electric fan body 1 by one step. Then, a series of operations as the remote controller 2 is completed in step S18.

  When the infrared signal reaches the light receiving section 68 of the electric fan main body 1, if the electric fan main body 1 is in operation, the air volume of the air blowing section 13 becomes one step lower than before. When the infrared ray signal including the air volume DOWN code from the remote controller 2 is received by the light receiving section 68, the control section 69 of the electric fan main body 1 executes the step S22 of the remote controller 2 in order to match the setting contents of the electric fan main body 1 and the remote controller 2. A procedure similar to steps S25 to S25 is executed with the setting content storage unit 84.

  FIG. 16 shows a control procedure of the remote controller 2 when the transfer button 58H is operated. The transfer button 58H is operated by the user's will when the actual operation of the electric fan body 1 does not match the setting contents of the remote control 2 displayed on the remote control display section 61. In FIG. 7, when the transmission control unit 75 of the remote controller 2 receives an operation signal associated with an operation on the transfer button 58H in step S31, the transmission control unit 75 stores the operation signal in the setting content storage unit 84 of the electric fan body 1 in the next step S32. In order to clear all the setting contents, the remote control transmitting unit 63 transmits an infrared signal including an all reset code which is a part of the above-mentioned reset signal.

  When the infrared ray signal is received by the light receiving section 68, the fan main body 1 is reset to the initial state by resetting all the setting contents stored so far in the setting content storage section 84 by the control section 69.

  In step S33, the transmission control unit 75 of the remote controller 2 counts the processing time (about 0.3 seconds) on the side of the electric fan body 1 during this time, and then in the next step S34, stores the current setting stored in the setting content storage unit 77. It is determined whether or not the operation state of the electric fan body 1 is in operation. Since the operation state of the fan body 1 is stored in the level of the air volume from the blower unit 13, if the air volume is any one of 1 to 7, the transmission control unit 75 of the remote controller 2 determines that the fan body 1 is operating. Then, in the next step S35, the infrared signal including the air volume UP code of the same number of times as the air volume level from the air blowing unit 13 stored in the setting content storage unit 77 is sent to the remaining part. Is transmitted from the remote control transmission unit 63 as the reset signal of

  For example, if the level of the air volume from the air blowing unit 13 stored in the setting content storage unit 77 is “5”, the infrared signal including the air volume UP code is transmitted from the remote control transmitting unit 63 five times at regular intervals. You. The control unit 69 of the electric fan body 1 receiving this by the light receiving unit 68 sets the operation state of the electric fan body 1 to the operation in which the air volume level is 5 and also sets the air volume level from the blower 13 to 5, and sets the respective settings. The data is overwritten and stored in the storage unit 84. Thereafter, the control unit 69 of the electric fan main body 1 can control the operation of the air blowing unit 13 so that air is blown with the same settings as those on the remote controller 2 side.

  Thereafter, the remote controller 2 proceeds to step S36, in which the display controller 76 causes the remote controller display 61 to display the level of the air volume from the blower unit 13 stored in the setting content storage unit 77. Ends in step S37. Also at this time, the remote control display unit 61 turns on the backlight 60 for a certain period of time with the level of the air volume from the blower unit 13 displayed on the level display unit 59C of the LCD 59.

  FIG. 17 shows a control procedure of the electric fan main body 1 when an infrared signal including the above-mentioned all reset code is received. In FIG. 7, when the light receiving section 68 receives an infrared signal including an all-reset code in step S41, the control section 69 of the electric fan body 1 clears all setting contents stored in the setting content storage section 84. In order to return to the initial state, in the next step S42, the operation state of the electric fan body 1 also sets the air flow level to 0, that is, turns off, and in the following step S43, the air flow (storage air flow) level from the blower unit 13 is also set to 0. Then, if there is a display unit for the air volume on the side of the fan main body 1, the process proceeds to step S44, where the air volume in the initial state is displayed on the display unit, and a series of procedures is ended in step S45. The subsequent operation procedure on the side of the fan main body 1 is as described above.

  In the flowcharts of FIGS. 13 to 17, the setting content related to the air volume of the blower unit 13 has been mainly described, but the other setting content is basically processed in a similar procedure. For example, by operating the swing button 58B on the remote controller 2 side, an infrared signal including a swing angle switching code for switching the swing angle of the blower 13 is transmitted from the remote controller transmitter 63 to the light receiver 68 of the fan body 1. Is reached, the swing control unit 83 controls the operation of the swing motor 79 so that the swing angle of the blower unit 13 is 0 ° (that is, swing release), 50 °, and 80 °. It is also possible to switch over to any one of them and to overwrite and store in the setting content storage unit 84. At this time, the display control unit 76 of the remote controller 2 transmits the swing angle to 0 ° in order to inform the user of the swing angle of the blowing unit 13 from the remote control display unit 61. When the display 59A is not turned on and the swing angle is switched to 50 °, “50 °” of the swing angle display 59A is turned on, and when the swing angle is switched to 90 °, the swing angle is changed. “90 °” on the display section 59A is turned on.

  Also, by operating the random switching button 58C on the remote controller 2 side, an infrared signal including a random switching code for switching the type of air blowing from the air blowing unit 13 is transmitted from the remote control transmitting unit 63 to the light receiving unit 68 of the fan body 1. Each time the air blows, the blower controller 81 controls the operation of the DC fan motor 21 so that the air flow from the blower unit 13 is constant and does not change, and the air flow from the blower unit 13 changes in a complicated manner due to the strong and weak air flow. It is also possible to switch to any of the random styles each time and overwrite and store in the setting content storage unit 84. At this time, the display control unit 76 of the remote controller 2 switches the air flow to the random air in order to notify the user of whether the air is being aired by the continuous air or the random air from the remote control display unit 61. In this case, the random display portion 59B is turned on, and when the air is switched to the continuous air, the random display portion 59B is turned off.

  Further, while the fan main body 1 is operating, the infrared signal including the timer off code for automatically stopping the operation of the fan main body 1 by operating the timer off button 58F on the remote control 2 side is transmitted from the remote control transmitting unit 63. Each time the light reaches the light receiving section 68 of the electric fan main body 1, the timer expiration time until the control section 68 stops the operation of the electric fan main body 1 is set to, for example, 0 hour (that is, timer release), 1 hour, and 2 hours. Alternatively, the setting may be switched to any one of the four hours, and the setting content storage unit 84 may be overwritten and stored. At this time, the display control unit 76 of the remote control 2 displays the set timer expiration time at the user's hand from the remote control display unit 61 when the timer expiration time is switched to 0 hour. When the timer-off time is switched to 1 hour without turning on 59D, "1" of the timer-off time display section 59D is turned on, and when the timer-off time is switched to 2 hours, the timer-off time display section 59D is displayed. Is turned on, and when the timer cut-off time is switched to 4 hours, "4" of the timer cut-off time display section 59D is turned on. If the new timer cut-off time set by overwriting and storing in the setting content storage unit 84 is other than 0 hour, the control unit 69, when the time counted by the timer unit 52 reaches the set timer cut-off time, The operation of the electric fan body 1 is automatically stopped, and if the set new timer expiration time is 0 hour, such automatic stop is released.

  On the other hand, while the operation of the fan main body 1 is stopped or after setting the timer expiration time, the timer on button 58G is operated on the remote controller 2 to automatically start the operation of the fan main body 1. Each time the infrared signal reaches the light receiving unit 68 of the fan main body 1 from the remote control transmitting unit 63, the timer input time until the control unit 68 starts operating the fan main body 1 is set to, for example, 0 hour (that is, the timer release time). ), 2 hours, 4 hours, or 6 hours, and the setting can be overwritten and stored in the setting content storage unit 84. At this time, the display control unit 76 of the remote control 2 transmits the set timer input time to the user by using the remote control display unit 61 so that the timer input time is switched to 0 hour. When the timer ON time is switched to 2 hours without turning on 59E, "2" of the timer ON time display section 59E is turned on, and when the timer ON time is switched to 4 hours, the timer ON time display section 59E is displayed. Is turned on, and when the timer input time is switched to 6 hours, "6" of the timer input time display section 59E is turned on. If the new timer entry time set by overwriting and storing in the setting content storage unit 84 is other than 0 hour, the control unit 69, at the time when the time counted by the timer unit 52 reaches the set timer entry time, The operation of the electric fan body 1 is automatically started, and if the set new timer ON time is 0 hour, such automatic start is canceled.

  The setting range storage 77 of the remote controller 2 includes the swing range of the blower 13, the type of blown air from the blower 13, and the timer ON time and the timer OFF time of the electric fan 1. All the setting contents are newly stored in the setting content storage unit 84 after the transfer button 58H is operated to clear all the setting contents stored in the setting content storage unit 84 of the electric fan body 1. It has become.

  Next, the operation during the operation of the fan body 1 will be described. When the blower fan 22 rotates by energizing the DC fan motor 21 during the operation of the fan body 1, the induced electromotive force from the power generation unit 41 is supplied to the power supply unit 42. Is supplied to the white LED 49 of the display unit 43 via the lead wire 48 of FIG. Thereby, the light emitted from the white LED 49 is guided to the monogram 50, and the entire monogram 50 emits white light on the front side of the fan guard 23, and the brightness of the monogram 50 is adjusted in real time according to the rotation speed of the blower fan 22. Changes to Therefore, if the remote controller 2 is detached from the fan main body 1, the person around the fan main body 1 can immediately visually check the current air volume of the blower 13 from the degree of brightness of the monogram 50. Becomes possible.

  Further, here, the white LED 49 and the monogram 50 that constitute the display unit 43 are provided on the fan guard 23 that constitutes the blower unit 13, and the person around the fan main body 1 can use the current standing posture. The air volume of the air blower 13 can be visually recognized well by a planar light emission display from the entire monogram 50. For this reason, in the present embodiment as well, it is possible to differentiate products by display in store displays and the like.

  Moreover, in the present embodiment, the circular display from the monogram 50 whose brightness changes in accordance with the rotation speed of the blower fan 22 is provided by providing the monogram 50 on the disk portion 35 located at the center of the front surface of the fan guard 23. Can be performed at the outer peripheral portion of the front surface of the blower 13. This makes it possible to significantly enhance the visual effect of the product in a store display or the like.

  As described above, in the present embodiment, the remote controller 2 that includes the fan main body 1 that has the blower unit 13 that functions as a blower and the remote controller 2 that remotely controls the fan main body 1 is provided. The electric fan main body 1 includes a remote control operation section 58 for setting the operation of the electric fan main body 1 and a remote control display section 61 for displaying the setting contents operated by the remote control operation section 58. When the setting contents from the remote controller 2 are received by the light receiving unit 68 serving as a receiving unit in conjunction therewith, the setting contents stored in the setting content storage unit 84 are changed, and the load (operation) including the blower unit 13 is changed by the setting contents. The lamp 17, the DC fan motor 21, and the swinging motor 79) are controlled, and the remote controller 58 has a transfer button 58 </ b> H serving as a reset operation body. Then, all the setting contents stored in the setting content storage unit 84 of the fan main body 1 are cleared, and all the setting contents stored by the remote controller 2 are newly stored in the fan main body 1. Is transmitted, the transmission controller 75 of the remote controller 2 is configured.

  In this case, if the setting contents of the remote controller 2 do not match the setting contents of the electric fan main body 1, only the transfer button 58H is operated to clear the setting contents of the electric fan main body 1 once, and then the remote control 2 side All the setting contents can be newly stored in the fan main body 1 side. Therefore, it is possible to avoid the troublesome operation, reflect the setting contents on the remote controller 2 side to the fan main body 1 side, and display the same setting contents on which the fan main body 1 operates on the remote control display section 61. In addition, this can be realized only by adding a process of clearing the setting content of the fan main body 1 before the normal process of changing the setting content of the fan main body 1 with a remote operation from the remote control 2 side. In addition, the software configuration of the electric fan can be simplified.

  Also, in this embodiment, after the operation of the fan main body 1 is set by the remote control operation unit 58, the remote control display unit 61 is turned off after a certain period of time has elapsed, and when the remote control operation unit 58 is operated again, the remote control display A display control unit on the remote controller 2 side so that the unit 61 continuously displays the previous setting content stored in the setting content storage unit 77 or displays the default setting content stored by default. 76 is controlled.

  Thus, the power of the remote controller 2 can be reduced by turning off the remote controller display unit 61 after the operation of the electric fan main body 1 is set by the remote controller operation unit 58. In addition, when the remote controller 2 is used again, the previous setting contents or the initial state setting contents are displayed on the remote control display unit 61, so that the usability as the remote control 2 can be improved.

  Further, the remote control display unit 61 of the present embodiment is configured by an LCD 59 with a backlight 60 that can be displayed by driving the batteries 65A and 65B. When the remote control operation unit 58 is operated, the backlight 60 is turned on. When not operating the backlight 58, the backlight 60 is turned off.

  In this case, the LCD 59 is brightened by the backlight 60 to improve the visibility of the remote control display unit 61 when the remote control operation unit 58 is operated, and the backlight 60 is turned off when the remote control operation unit 58 is not operated. Power consumption of the batteries 65A and 65B can be suppressed.

  Further, in the present embodiment, when the remaining amount of the batteries 65A and 65B is lower than a predetermined value, the backlight 60 is not turned on without being turned on when the remote control operation unit 58 is operated, or the LCD 59 is turned off. The display controller 76 of the remote controller 2 is configured to display the remaining amount of the batteries 65A and 65B.

  In this case, when the remaining amount of the batteries 65A and 65B decreases, the backlight 60 can be kept off even if the remote control operation unit 58 is operated, and the power consumption of the batteries 65A and 65B can be suppressed. , 65B can be confirmed by the display from the remote control display unit 61 at hand by the user.

  Further, the fan main body 1 of the present embodiment includes a blower fan 22 surrounded by a fan guard 23 serving as a guard, and the remote controller 2 is detachably provided on a front side of a monogram 50 forming an outer surface of the fan guard 23, The transmission control unit 75 and the display control unit 76 are configured so that the display on the remote control display unit 61 is continued during the operation of the electric fan body 1 and the operation on the remote control operation unit 58 is received.

  Here, the operation of the fan main body 1 includes not only the air being blown by the blower unit 13 but also the standby of the fan main body 1 until the timer enters. Further, in order to continue the display of the remote control display unit 61 during the operation of the electric fan main body 1, when the operation state of the electric fan main body 1 is determined to be in operation or the timer ON time is set to other than 0 hour. In this case, the setting contents may be kept displayed on the LCD 59.

  In this manner, if the remote controller 2 is attached to the front side of the monogram 50, for example, which is the outer surface of the fan guard 23 of the electric fan main body 1, the user can use the display from the remote control display unit 61 while the electric fan main body 1 is operating. The settings of the operation of the fan body 1 can be checked at any time, and the settings of the operation of the fan body 1 can be changed at any time by operating the remote control operation unit 58.

  In addition, in the present embodiment, a blower unit 13 configured by surrounding a rotating blower fan 22 with a fan guard 23, a support base 15 that supports the blower unit 13 from a floor surface S, and a display unit provided on the fan guard 23. 43 and a power generation unit 41 for converting the rotational force of the blower fan 22 into electric power are provided in the fan main body 1, and electric power that changes according to the rotation speed of the blower fan 22 is supplied to the display unit 43 via the lead wire 48. The power generation unit 41 is configured to supply the power.

  In this case, by supplying power corresponding to the rotation speed of the blower fan 22 from the power generation unit 41 to the display unit 43, the brightness of the display unit 43 can be changed in real time in accordance with the rotation speed of the blower fan 22, The current air volume of the air blower 13 can be visually recognized on the spot. In addition, by providing the display unit 43 not on the support base 15 supporting the blower unit 13 but on the fan guard 23 forming the blower unit 13, the current air volume can be visually recognized in a standing posture. Products can be differentiated by display even at exhibitions.

  In addition, the display unit 43 of the present embodiment includes a white LED 49 as a light emitting element that receives power from the power generation unit 41 and a monogram 50 as a light guide that guides the light of the white LED 49 and emits light. .

  For this reason, a fan with improved visibility can be provided by guiding the light from the white LED 75 to the monogram 50 and emitting light in a planar manner, instead of a spot-like display using only the white LED 49.

  Further, in the present embodiment, a monogram 50 serving as a light guide plate is arranged at the center of the front surface of the fan guard 23, located in front of the rotation center of the blower fan 22.

  In this case, the monogram 50 provided at the center of the front surface of the fan guard 23 displays a planar display that changes according to the rotation speed of the blower fan 22 at the rotation center position of the blower fan 22 which is a base point of the blower unit 13. Can be performed. As a result, it is possible to provide a fan that has a remarkably enhanced visual effect in store displays and the like.

  Further, in this embodiment, a pair of monogram magnets 51A and 51B provided in the fan main body 1 and a pair of monogram magnets 51A and 51B, which can be attracted to the monogram magnets 51A and 51B, are provided in the remote control 2 as an attachment / detachment mechanism for the fan main body 1 and the remote controller 2. It consists of a pair of remote control magnets 52A, 52B, and is arranged with the polarities of the monogram magnets 51A, 51B reversed.

  Thus, it is possible to prevent the remote controller 2 from being mounted upside down while having a simple configuration. Further, since the remote controller 2 is mounted in the correct direction without the characters on the character sheet 55 and the display on the remote controller display section 61 being upside down, the user U always operates the remote controller operation section 58 in a predetermined direction. And the display from the remote control display unit 61 can be confirmed.

  FIG. 18 and FIG. 19 both show the appearance of a fan including the fan main body 1 and the remote controller 2 according to the second embodiment of the present invention. FIG. 20 is an exploded view of a main part of the fan main body 1, and FIG. 21 is a perspective view of a main part of the fan main body 1.

  In each of these drawings, a description will be given of a configuration different from that of the first embodiment. The electric fan main body 1 is different from the operation lamp 17 of the first embodiment in addition to a main body operation unit 101 including a plurality of keys and buttons described later. An operation panel 103 having a main body display unit 102 such as an LED is disposed in front of the upper surface of the base 11. The light receiving section 68 includes three infrared communication signal sensors 68A, 68B, and 68C arranged so that the directions of the reception directivities are different from each other. The infrared communication signal sensors 68A, 68B, and 68C themselves are widely distributed as sensors for receiving infrared signals from the remote controller 2, and cost reduction can be achieved as compared with a conventional current-collecting infrared detection sensor. it can. The number of sensors is not particularly limited as long as it is plural.

  The infrared communication signal sensors 68A, 68B, and 68C have the same configuration, and include a light receiving element 105 having a light receiving surface for receiving an infrared signal, and a light receiving surface for restricting an entry path of the infrared signal to the light receiving element 105. And a linear cylindrical directional tube 106 disposed at the front. The directional tube 106 is open at both ends in the length (axial) direction, one end of which is attached to the light receiving element 105 so as to face the light receiving surface of the light receiving element 105, and the other end is formed on the side surface of the base 11. Window 107 that has been opened. Therefore, the number of the window holes 107 provided in the base 11 is the same as that of the infrared communication signal sensors 68A, 68B, 68C.

  In this embodiment, as shown in FIG. 21, the infrared communication signal sensors 68A, 68B, 68C and the window holes 107 are respectively provided around the column 12 in different radiation directions from the column 12 toward the side surface of the base 11. You. Specifically, when the electric fan main body 1 is viewed from the front, the first infrared communication signal sensor 68A is disposed on the left side of the base 11, the second infrared communication signal sensor 68B is disposed at the center of the base 11, The third infrared communication signal sensor 68C is arranged on the right side of the base 11. The first infrared communication signal sensor 68A is disposed in a radiation direction extending from the support 12 to the second infrared communication signal sensor 68B in a radiation direction extending at an angle αL of 45 ° to the left from the reference 0 °. The third infrared communication signal sensor 68C is disposed on the opposite right side in a radial direction extending at an angle αR of 45 °.

  Note that the left and right angles αL and αR described above may be, for example, 70 ° other than 45 °. Further, a window hole 107 may be formed not only on the side surface of the base 11 but also on the upper surface of the base 11, and the infrared communication signal sensor may be provided facing the window hole 107. In any case, in order to correctly specify the direction of the remote controller 2 that emits the infrared signal, each of the infrared communication signal sensors 68A, 68B, and 68C is configured so that the directional tubes 106 do not point in the same direction, that is, the reception directivity. Are arranged inside the base 11 at predetermined intervals so that the directions of the directions are different from each other.

  In the present embodiment, with a simple configuration in which a cylindrical directional tube 106 is provided in front of the light receiving element 105, only an infrared signal that enters the directional tube 106 from the window hole 107 in a specific direction is transmitted. The light can reach the light receiving surface of the light receiving element 105. This allows the light receiving element 105 itself to have the receiving directivity of the infrared signal, so that the light receiving element 105 can reliably receive an infrared signal from a specific direction.

  In addition, the base 11 is originally formed to have a flat shape in a relatively wide range with respect to the floor surface S in a plan view so that the electric fan main body 1 is not easily tilted. It is preferable to provide the base 11 in a wider range than the support 12 and the blower 13. If the base 11 is used as a mounting portion of the light receiving section 68, the infrared communication signal sensors 68A, 68B, 68C can be arranged at a sufficient interval, and even if a radio signal is emitted from any direction, The wireless signal is reliably received by the light receiving unit 68, and the recognition accuracy of the wireless signal can be improved.

  The power supply unit 42 incorporated in the blower unit 13 can supply the induced electromotive force generated by the power generation unit 41 not only to the display unit 43 provided on the fan guard 23 but also to the remote controller 2 mounted on the front side of the monogram 50. In addition, in addition to the lead wire 48 of the first embodiment, an electrode 108 serving as a terminal for supplying power to the remote controller 2 and the like are provided. The conductive electrode 108 is arranged on the front surface of the monogram 50, and holds the remote controller 2 on the front side of the monogram 50 by using the magnetic force between the monogram magnets 51A, 51B and the remote controller magnets 52A, 52B. At this time, power is supplied to the remote controller 2 via the electrode 108. The batteries 65A and 65B incorporated in the remote controller 2 are secondary batteries, and the power supplied from the power generation unit 41 is stored in the batteries 65A and 65B, and the batteries 65A and 65B are used even when the remote controller 2 is used alone. Each unit of the remote controller 2 can be operated with the stored power. As a modified example, a movable shutter mechanism that exposes the electrode 108 only when the remote controller 2 is mounted on the monogram 50 may be provided in the fan guard 23.

  FIG. 22 shows the appearance of the operation panel 103 provided on the upper surface of the base 11. In the figure, an operation panel 103 includes the main body operation unit 101 and the main body display unit 102 described above. The main body operation unit 101 includes a plurality of operation bodies that can be pushed and operated, including an operation off / on button 111A, a random switching button 111B, a high air volume button 111C, a low air volume button 111D, and a vertical swing button. 111E, a left and right swing button 111F, a sensor operation button 111G, a timer off button 111H, and a timer on button 111I. In this embodiment, each time the operation off / on button 111A of the main body operation unit 101 is pressed, the operation of the fan main body 1 is switched to either start or stop.

  The main body display unit 102 includes signal reception lamps 112A, 112B, 112C, a room temperature display unit 113A, a humidity display unit 113B, an air volume display unit 113C, a vertical swing lamp 114A, a left and right swing lamp 114B, and a sensor operation. It comprises a mode lamp 114C, a timer off lamp 114D, and a timer on lamp 114E. Among them, the signal receiving lamps 112A, 112B, 112C of the display unit 102 are respectively arranged along the circumferential side surface of the base 11 corresponding to the infrared communication signal sensors 68A, 68B, 68C.

  FIG. 23 shows a main electric configuration of the electric fan. Compared to the electric fan of the first embodiment, the electric fan main body 1 of the present embodiment has a main body transmitting unit 121, a room temperature sensor 122, and a humidity sensor 123 in addition to the main body operation unit 101 and the main body display unit 102 described above. The remote controller 2 is additionally provided with a light receiving unit 124. With respect to these added configurations, the main body operation unit 101, the room temperature sensor 122, and the humidity sensor 123 are electrically connected to the input ports of the control unit 69 on the side of the electric fan body 1, respectively, and are connected to the output ports of the control unit 69. The main body display unit 102 and the main body transmission unit 121 are electrically connected. The light receiving section 124 is electrically connected to an input port of the microcomputer 64 on the remote controller 3 side.

  The main body transmitting unit 121 includes one or more infrared LEDs (not shown) for transmitting an infrared signal to the light receiving unit 124 on the remote controller 2 side. Thereby, in this embodiment, two-way wireless communication is possible from the main body transmission section 121 of the fan main body 1 to the light receiving section 124 of the remote control 2 and from the remote control transmission section 63 of the remote control 2 to the light receiving section 68 of the fan main body 1. become. In addition, the room temperature sensor 122 is incorporated in the fan main body 1 as a temperature detecting means for detecting the room temperature that is the peripheral temperature of the fan main body 1, and the humidity sensor 123 is installed in the fan main body 1 as a humidity detecting means for detecting the humidity around the electric fan main body 1. It is.

  The control unit 69 of the electric fan main body 1 includes a display control unit 126 that mainly controls the operation of the main body display unit 102 as a software function instead of the operation lamp control unit 82 of the first embodiment. Further, each time the control unit 69 receives an operation signal from the main body operation unit 121 and overwrites and stores the new setting content in the setting content storage unit 84, the control unit 69 transmits an infrared signal including a unique code corresponding to the new setting content. Is further provided with a transmission control unit 127 that controls the main body transmission unit 121 so that is transmitted from the main body transmission unit 121. Therefore, in the present embodiment, not only the operation from the remote control operation unit 58 but also the operation from the main unit operation unit 101 can change the setting content of the operation of the electric fan main unit 1 and overwrite and store the setting content in the setting content storage unit 84. The changed setting contents are displayed on the main body display unit 102 by the display control unit 126 each time.

  On the other hand, when the microcomputer 64 of the remote controller 2 receives the infrared signal including the unique code from the main body transmission unit 121 by the light receiving unit 124, the setting content up to that time stored in the setting content storage unit 77 is received by the light receiving unit 124. As a software function, a new configuration is provided in which the setting content corresponding to the unique code received in step (1) is changed and overwritten and stored, and the changed setting content is displayed on the remote control display unit 61 by the display control unit 76.

  The other configuration is common to that of the first embodiment, and the operation procedure associated with the operation on the remote control operation unit 58 is also the same as that described in the flowcharts of FIGS. I do.

  Regarding the electric fan having the above configuration, the operation of the electric fan main body 1 in accordance with the operation of the main body operation unit 101 will be described first. When the control unit 69 starts the operation of the electric fan body 1 in response to the operation signal from the operation off / on button 111A, the air blowing control unit 81 sets the air blowing unit at the air volume level stored and held in the setting content storage unit 84. A control signal for supplying an appropriate drive signal to the DC fan motor 21 so that air is blown from the control unit 13 is sent out, and the swing control unit 83 also performs the swing control stored in the setting content storage unit 84. Another control signal for supplying an appropriate drive signal to the swing motor 79 is transmitted so that the blower unit 13 swings right and left and / or up and down at an angle in the range.

  The display control unit 126 causes the air volume display unit 113C to display the level of the air volume from the air blowing unit 13 stored in the setting content storage unit 84 during the operation of the electric fan body 1. The air volume from the air blowing unit 13 is controlled by the air blowing control unit 81, and the level of the air volume increases by one level each time the strong air volume button 111C is pressed, and the level of the air volume decreases by one level each time the weak air volume button 111D is pressed. The changed airflow level is overwritten and stored in the setting content storage unit 84. When the changed air volume level is overwritten and stored in the setting content storage unit 84, the transmission control unit 127 transmits an infrared signal including a unique code corresponding to the air volume level from the main body transmission unit 121 to the remote controller 2. I do.

  When this is received by the light receiving unit 124 of the remote controller 2, the microcomputer 64 causes the setting content storage unit 77 to overwrite and store the changed airflow level instead of the airflow level previously stored, and the display control unit 76 The level is displayed on the level display section 59C of the LCD 59. That is, the high air volume button 111C and the low air volume button 111D of the electric fan body 1 have the same functions as the air volume UP button 58D and the air volume DOWN button 58E of the remote controller 2, and the operation procedure of the electric fan body 1 is also the same as the first embodiment. Is the same as the operation procedure (steps S11 to S18, S21 to S28) of the remote controller 2 in step S11.

  In addition, although detailed procedures are partially omitted because they are duplicated, each time the random switch button 111B is pressed, the continuous air flow from the blower unit 13 that is constant and does not change, and the air flow from the blower unit 13 is strongly and weakly complicated. Switch to one of the changing random winds. The display control unit 126 causes the air volume display unit 113C to display not only the currently set air volume but also whether the continuous or random air is being supplied. That is, the random switching button 111B and the air volume display section 113C of the electric fan body 1 have the same functions as the random switching button 58C and the random display section 59B of the remote controller 2.

  During operation of the electric fan body 1, detection signals from the room temperature sensor 122 and the humidity sensor 123 are taken into the control unit 69. Utilizing this, the display control unit 126 causes the room temperature display unit 113A to display an indication of the room temperature and causes the humidity display unit 113B to display an indication of the humidity. Further, each time the sensor operation button 111G is pressed, the sensor operation mode set in accordance with the detection results of the room temperature sensor 122 and the humidity sensor 123 is selected or canceled, for example, to any of strong, standard, and weak. You. During the operation in the sensor operation mode, in addition to the room temperature detected by the room temperature sensor 122 and the room temperature detected by the humidity sensor 123, an appropriate air volume is selected according to the selected strong, standard, or weak mode. Is automatically set by the air blowing control unit 81, and the air blowing control unit 65 controls the operation of the DC fan motor 21 so that air is blown from the air blowing unit 13 at the set air volume. Here, too, the display control unit 126 displays the set air volume on the air volume display unit 113C, and causes the sensor operation mode lamp 114C to display which mode is selected.

  Each time the timer off button 111H is pressed during operation of the electric fan body 1, the timer off time until the operation is stopped is, for example, 0 hour (timer release), 1 hour, 2 hours, and 4 hours. Is set to any of When the control section 69 sets the timer cut-off time in response to the operation signal from the timer cut-off button 111H, the set timer cut-off time is displayed on the timer cut-off lamp 114D by the display control section 126 (the light is turned off in the case of 0 hour). When the time counted by the built-in timer reaches the set timer expiration time, the operations of the DC fan motor 21, the display unit 51, and the oscillating motor 64 are terminated, and the electric fan body 1 The operation of is automatically stopped. That is, the timer-off button 111H and the timer-off lamp 114D of the electric fan body 1 have the same functions as the timer-off button 58F and the timer-off time display section 59D of the remote controller 2.

  On the other hand, every time the timer on button 111I is pressed after the operation of the electric fan body 1 is stopped or after the timer off time is set, the timer on time until the operation is started is, for example, 0 hour (that is, the timer is released). It is set to one of two hours, four hours, and six hours. When the control unit 63 receives the operation signal from the timer input button 111I and sets the timer input time, the set timer input time is displayed on the timer input lamp 114E by the display control unit 126. ), And when the time counted by the built-in timer reaches the set timer input time, the operation of the electric fan body 1 is automatically started. That is, the timer input button 111I and the timer input lamp 114E of the electric fan main body 1 have the same functions as the timer input button 58G and the timer input time display section 59E of the remote controller 2.

  The operation of the swing operation of the blower unit 13 will be described. During the operation of the fan body 1 that blows air from the blower 13, each time the up / down swing button 111E is pressed, the up / down swing operation is turned on or off. Switch. When the up / down swing operation is turned on in response to the operation signal from the up / down swing button 111E, the swing control unit 83 controls the swing motor 79 to swing the blower unit 13 vertically. Control behavior. The display control unit 126 turns on the up / down swing lamp 114A when the up / down swing operation is switched on, and turns off the up / down swing lamp 114A when the up / down swing operation is switched off.

  On the other hand, for the left and right swing operation, each time the left and right swing button 111F is pressed while the electric fan body 1 is operating, the left and right swing operation mode is set to 0 ° (no swing) in which the swing angle is fixed or The display switches to 90 ° or “Preference” where the swing range can be set arbitrarily. The 90 ° swing operation mode, which is the first mode, is set by pressing the left and right swing button 112F once from the state in which the left and right swing operation mode is released. At this time, the blower control unit 81 determines a predetermined angle from the left and right swing center lines when the blower unit 13 is viewed from the front, that is, an angle of 45 ° to the left, and the same 45 ° to the right. The operation of the swing motor 79 is controlled so that the blower 13 swings in the left-right direction within the range of the angle. When the mode of the left and right swing operation is switched to 90 °, the display control unit 126 turns on only the lamp corresponding to “90 °” of the left and right swing lamp 54B.

  Note that the left and right angles described above may be other than 45 °. However, in the first mode, no matter how the main body operation unit 101 or the remote control operation unit 58 is operated, the preset angle cannot be changed.

  The favorite swing operation mode, which is the second mode, is set by pressing the left and right swing button 112F twice from the state in which the left and right swing operation mode is cancelled. At this time, the blower controller 81 controls the blower 13 to swing in the left-right direction within the range of the left and right angles arbitrarily set by the person from the left and right swing center line C as a reference. Next, the operation of the swing motor 79 is controlled. Further, when the mode of the left and right swing operation is switched to your preference, the display control unit 126 turns on only the lamp corresponding to “favorite” of the left and right swing lamp 114B.

  In the second mode, the left and right angles are variably set by appropriately operating the operation unit 41 and the remote control operation unit 28 of the electric fan body 1, and stored in the storage unit 68. In the present embodiment, while the angle from the left and right swing center line to the left end is set to, for example, 20 °, the angle to the right end can be set to, for example, a different 50 °, and then the second mode is set. Then, the left and right swing operation can be restarted at that angle. Therefore, the left and right swing center lines corresponding to the swing center position of the blower 13 in the present embodiment are always at the center of the left and right swing range in the first mode, but are not necessarily left and right in the second mode. Is not necessarily at the center of the swing range, and in this case, it is a reference when variably setting the left and right swing ranges.

  In this embodiment, the left and right swing center lines with respect to the fan main body 1 can be designated by direct operation or remote operation. The direct operation utilizes the mechanical part of the swinging device 14 to move the blowing unit 13 and the swinging unit 14, which are movable parts with respect to the support column 12, by hand, so that the left and right swinging center lines and thus the blowing unit are moved. The wind direction from 13 can be adjusted appropriately. Although not shown, the wind direction from the blower 13 can also be manually adjusted appropriately in the vertical direction.

  The display control unit 126 of the electric fan main body 1 operates the signal reception lamps 112, 112B, 112C of the main body display unit 102 for a predetermined time in response to the infrared communication signal sensors 68A, 68B, 68C that have received the infrared signal from the remote controller 2. Turn on. Thus, it is possible to immediately understand which of the infrared communication signal sensors 68A, 68B, 68C has detected the infrared signal after the operation on the remote control operation unit 58.
