  FIG. 9 shows the electrical configuration of the electric fan in this embodiment. In the figure, reference numeral 41 denotes a control unit including a microcomputer disposed on the pedestal 2 of the electric fan main body 1, and the input port of the control unit 41 includes a remote control transmitter 51 in addition to the main body operation unit 8 described above. While a receiving unit 42 that receives a remote control operation signal is connected, a DC fan motor 15 that constitutes the air blowing unit 4 and a first stepping motor that constitutes the left and right swinging unit 23 are connected to the output port of the control unit 41. 26 and a second stepping motor 27 constituting the upper and lower head swing part 24 are connected to each other. The remote control transmitter 51 includes a remote control operation unit 52 composed of the plurality of operation buttons described above, and a remote control operation signal generated inside the remote control transmitter 51 when the remote control operation unit 52 is operated. In addition, the signal is wirelessly transmitted to the receiving unit 42 of the electric fan main body 1 through a transmitting unit (not shown).

  The control unit 41 receives the operation signal generated from the main body operation unit 8 as a software function by the microcomputer or the reception unit 42 from the remote control transmitter 51 as the remote control operation unit 52 is pushed. In response to the remote control operation signal, the air blow control unit 44 that controls the operation of the DC fan motor 15, the left / right swing control unit 45 that controls the operation of the first stepping motor 26, and the operation of the second stepping motor 27 are controlled. A vertical swing control unit 46 to be controlled is provided. The control unit 41 includes a position detection unit 43 that detects position information corresponding to the direction of the blower unit 4. The control unit 41 not only operates the electric fan body 1 but also stops the operation of the electric fan body 1 by the pressing operation of the power button 30, position information corresponding to the direction of the air blowing unit 4, and the air volume from the air blowing unit 4. The storage unit 47 stores various setting states such as the left and right swing ranges of the blower unit 4 and the upper and lower swing ranges of the blower unit 4. The setting state stored in the storage unit 47 is read when the power button 30 is pushed again and the operation of the electric fan body 1 is restarted. The head swing device 6 can be operated.

  Next, the effect | action is demonstrated about the electric fan of the said structure. First, the operation of the blower unit 4 will be described. When the operation of the electric fan body 1 is started by pushing the power button 30, the blower control unit 44 reads the set air volume of the blower unit 4 stored in the storage unit 47, A pulse drive signal with a duty corresponding to the set air volume is sent to the DC fan motor 15. As a result, the DC fan motor 15 and the fan 16 start to operate at the same rotational speed as immediately before the operation of the electric fan body 1 is stopped, and the set air volume is continuously generated from the blower unit 4.

  As shown in Table 1, in this embodiment, the air volume from the blower unit 4 can be set to any one of seven modes by pushing the remote control operation unit 52. In mode 1, the rotational speed of the DC fan motor 15 is set to 300 rpm. In modes 2 to 7, the rotational speed of the DC fan motor 15 is set to 450, 670, 830, 990, 1065, and 1140 rpm. In the present embodiment, since the air blow control unit 44 controls the pulse width of the DC fan motor 15, if the duty of the pulse drive signal to the DC fan motor 15 is further finely varied, more modes than those shown in Table 1 are possible. Thus, it is also possible to easily generate continuous air with different air volumes from the blower unit 4. Further, the rotational speed of the DC fan motor 15 shown here is merely an example.

  Also, in this embodiment, the wind switching button 31 is pushed to operate, instead of the continuous air blowing operation in which a constant amount of air is continuously generated from the air blowing unit 4 regardless of the passage of time, the air is blown with the passage of time. It is possible to perform a rhythm air blowing operation that periodically generates a variable air volume from the unit 4. When the air flow control unit 44 shifts to the rhythm air blowing operation, in any one of the four patterns shown in the following Table 2, the air volume from the air blowing unit 4 increases and decreases periodically and smoothly with time. The duty of the pulse drive signal is gradually changed, and this pulse drive signal is sent to the DC fan motor 15.

  Patterns 1, 3, 5, and 7 shown in Table 2 are set by pressing the air volume increasing button 34 or the air volume decreasing button 35 during the rhythm air blowing operation. Similarly, it is also possible to generate more patterns of rhythm winds in the blower unit 4.

  In pattern 1, the number of rotations of the DC fan motor 15 increases from a minimum of 120 rpm at a rate of 30 rpm every 0.2 seconds and reaches a maximum of 300 rpm after 1.2 seconds. And after 1.4 seconds, it decreases at a rate of 20 rpm every 0.2 seconds, and after 2.6 seconds, it decreases at a rate of 30 rpm every 0.2 seconds, and after 3 seconds, the minimum 120 rpm again. Thereafter, this one-cycle operation is repeated. In pattern 3, the rotational speed of the DC fan motor 15 increases from the minimum of 490 rpm at a rate of 30 rpm every 0.2 seconds and reaches the maximum of 670 rpm after 1.2 seconds. Then, after 1.4 seconds, it decreases at a rate of 20 rpm every 0.2 seconds, and after 2.6 seconds, it decreases at a rate of 30 rpm every 0.2 seconds. Thereafter, this one-cycle operation is repeated. In the pattern 5, the rotational speed of the DC fan motor 15 increases from the minimum 810 rpm at a rate of 30 rpm every 0.2 seconds and reaches the maximum 990 rpm after 1.2 seconds. And after 1.4 seconds, it decreases at a rate of 20 rpm every 0.2 seconds, and after 2.6 seconds, it decreases at a rate of 30 rpm every 0.2 seconds. Thereafter, this one-cycle operation is repeated. In the pattern 7, the rotational speed of the DC fan motor 15 increases from the minimum 960 rpm at a rate of 30 rpm every 0.2 seconds and reaches the maximum 1140 rpm after 1.2 seconds. Then, after 1.4 seconds, it decreases at a rate of 20 rpm every 0.2 seconds, and after 2.6 seconds, it decreases at a rate of 30 rpm every 0.2 seconds. Thereafter, this one-cycle operation is repeated. The pattern shown here is merely an example, and the minimum rotation speed, maximum rotation speed, time (seconds), and rate of increase / decrease in the rotation speed of the DC fan motor 15 are appropriately changed according to the fan specifications. Good.

  In this embodiment, the air blow control unit 44 controls the pulse width of the DC fan motor 15 to change the rotational speed of the DC fan motor 15 with the passage of time. Also, the rhythm wind can be generated from the blower unit 4 without stopping the energization of the DC fan motor 15. Therefore, it is possible to eliminate misrecognition by the user and provide a rhythmical wind to the user. Further, in this embodiment, the rhythm wind that changes the rotation speed of the DC fan motor 15 with the passage of time can be switched and controlled from among a plurality of patterns, so that a rhythmical wind suitable for each of a plurality of users is also obtained in this respect. Can be provided.

  Next, the operation of the swing device 6 will be described. When the left and right swing button 32 is pressed in a state where the power button 30 is pressed and the operation of the electric fan body 1 is started, the left and right swing control unit 45 is operated. Reads out the left and right swing ranges of the blower unit 4 stored in the storage unit 47 and sends a pulse drive signal corresponding to the swing range to the first stepping motor 26. Thereby, the rotational force by the 1st stepping motor 26 generate | occur | produces in the left-right swing part 23, and it can rock | fluctuate the ventilation part 4 repeatedly right and left within the set left-right swing range. Further, when the left button 38 or the right button 39 is pushed, the left / right swing control unit 45 sends a pulse drive signal corresponding to the direction of the left button 38 or the right button 39 to the first stepping motor 26. Thereby, the rotational force by the 1st stepping motor 26 generate | occur | produces in the left-right swing part 23, and the ventilation part 4 can be rock | fluctuated left or right.

  In addition, when the vertical swing button 33 is pressed in a state where the power button 30 is pressed to start the operation of the electric fan body 1, the vertical swing control unit 46 is stored in the storage unit 47. And a pulse drive signal corresponding to the swing range is sent to the second stepping motor 27. Thereby, the rotational force by the 2nd stepping motor 27 generate | occur | produces in the up-and-down swing part 24, and the ventilation part 4 can be swung up and down repeatedly within the set up-and-down swing range. In addition, when the upper button 36 or the lower button 37 is pushed, the vertical swing control unit 46 sends a pulse drive signal corresponding to the direction of the upper button 36 or the lower button 37 to the second stepping motor 27. Thereby, the rotational force by the 2nd stepping motor 27 generate | occur | produces in the up-and-down swing part 24, and the ventilation part 4 can be rock | fluctuated up or down.

  Since the left and right swing control unit 45 and the vertical swing control unit 46 can independently control the corresponding first stepping motor 26 and second stepping motor 27, respectively, a three-dimensional combination of up and down and left and right It is possible to repeatedly swing the air blowing unit 4 in motion.

  The blower unit 4 is swung by the control unit 41 (the left and right swing control unit 45 and the vertical swing control unit 46) described above, as well as the support table 21 that can be swung up and down and the receiving table 25 that can be rotated horizontally. And can be manually moved up and down and left and right.

  As described above, in the present embodiment, in the electric fan including the swing device 6 that swings the blower unit 4, the first stepping motor 26 and the second stepping that serve as a stepping motor as a drive source of the swing device 6. A motor 27 is mounted so that the range of swinging can be arbitrarily set by a remote control transmitter 51 as a remote control body.

  In this case, since the first stepping motor 26 and the second stepping motor 27 are used as the driving source of the swing device 6, the first stepping motor 26 and the second stepping motor 27 are operated by an operation from the remote control transmitter 51. The air blowing range by the air blowing unit 4 can be set without excess or shortage only by giving an appropriate pulse drive signal to the second stepping motor 27. Therefore, it is possible to arbitrarily set the swing range of the blower unit 4 by a user's remote operation at a position away from the fan main body 1 and blow air from the blower unit 4 to a desired range.

  Further, in this embodiment, in the electric fan provided with the swinging device 6 that swings the blower unit 4, the first stepping motor 26 and the second stepping motor 27 that are stepping motors as the drive source of the swinging device 6. And the direction of the blower unit 4 can be arbitrarily set by a remote control transmitter 51 serving as a remote control.

  In this case, since the first stepping motor 26 and the second stepping motor 27 are used as the driving source of the swing device 6, the first stepping motor 26 and the second stepping motor 27 are operated by an operation from the remote control transmitter 51. The air blowing unit 4 can be directed in an arbitrary direction easily and in a short time only by giving an appropriate pulse drive signal to the second stepping motor 27. Therefore, air can be quickly blown in a desired direction by directing the air blowing unit 4 in an arbitrary direction by a user's remote operation in a short time.

  FIG. 10 shows the external appearance of the remote control transmitter 61 in the second embodiment of the present invention. The remote control transmitter 61 of the present embodiment is similar to the remote control transmitter 51 of the first embodiment in that the power button 63, the wind switching button 64, the left / right swing button 65, the up / down swing button 66, the air volume increase button 67, the air volume. A down button 68 is provided, and the function of each operation button is the same as that of the remote control transmitter 51. Similarly to the remote control transmitter 51, the remote control transmitter 61 includes an upper button 68, a lower button 69, a left button 70, and a right button 71 that are direction operation buttons. Since this is different from the above, this point will be described. The remote control operation unit 62 of the remote control transmitter 61 is different in configuration from the remote control operation unit 52 of the remote control transmitter 51 in that it does not include an operation button corresponding to the enter button 40 of the remote control transmitter 51.

  In order to set the direction of the blower unit 4 to an arbitrary direction in a state where the blower unit 4 is not swinging, the direction operation button corresponding to the direction in which the blower unit 4 is to be directed is pressed and operated. The air blower 4 swings in this direction while long pressing the direction operation button, and when the long press of the direction operation button is released, the air swing operation of the air blower 4 stops. Therefore, when the user wants to change the blowing direction by the blower unit 4, the user pushes the direction operation button in the desired direction to swing the blower unit 4, and the long-press operation of the direction operation button at the desired position. By canceling and stopping the swing motion, the blower unit 4 can be directed in a desired direction. When the direction operation button is pressed and operated to swing the air blowing unit 4 and the air blowing unit 4 reaches any one of the left end 54, the right end 55, the upper end 56, and the lower end 57 without releasing the long pressing operation. The oscillating operation of the air blowing unit 4 is stopped.

  To set the swing range of the blower unit 4 while the blower unit 4 is swinging left and right, the direction in which the swing range is desired to be set while the blower unit 4 is swinging Press and hold the direction operation button corresponding to. The air blower 4 swings in this direction while long pressing the direction operation button. When the long push operation of the direction operation button is released, the position of the air blower 4 when the long push operation is released. Is set to the movable end in the direction where the In order to set the movable end in the other directions, the direction operation button corresponding to the direction in which the movable end is set is long pressed, and when the blower unit 4 reaches a desired position, the long press operation is canceled to move the movable end. Set. In this way, the movable end can be set in any direction, and the swing range of the blower unit 4 can be set. When the swing range is set, the blower 4 performs a swing operation within the movable range. In addition, the setting of the movable end of the air blower 4 can be set in any direction, up, down, left, and right as in the first embodiment, and can be set in any order from any direction.

  The present embodiment is different from the second embodiment in the function of the direction operation buttons. In this embodiment, in order to set the direction of the air blower 4 to an arbitrary direction in a state where the air blower 4 is not swinging, the direction operation button corresponding to the direction in which the air blower 4 is directed is pushed. Manipulate. When the direction operation button is pushed, the air blower 4 swings in this direction, and when the same direction operation button is pushed again, the air blower 4 swings. Therefore, when the user wants to change the blowing direction by the blower unit 4, the user pushes the direction operation button in the desired direction to swing the blower unit 4, and presses the same direction operation button again at the desired position. The air blowing unit 4 can be directed in a desired direction by moving and stopping the swinging operation.

  The direction operation button is pushed and operated to swing the air blowing unit 4. The air blowing unit 4 reaches one of the left end 54, right end 55, upper end 56, and lower end 57 without the same direction operation button being pushed again. In such a case, the swinging operation of the blower unit 4 is stopped. In addition, when a different direction operation button is pushed after the direction operation button is pushed and the air blower 4 is swung, the direction corresponding to the direction operation button that is pushed later is changed. The air blower 4 starts a swinging motion. Therefore, when the same direction operation button is pushed twice in succession, the blower unit 4 is set in an arbitrary direction.

  In the state where the blower unit 4 is swinging, in order to set the swing range of the blower unit 4, the direction operation button corresponding to the direction in which the swing range is desired to be set is pushed. When the direction operation button is pushed, the air blowing unit 4 swings in this direction, and when the same direction operation button is pushed again, the position of the air blowing unit 4 when the push operation is performed is movable in that direction. Set to the end. To set the movable end for other directions, push the direction operation button corresponding to the direction to set the movable end, and push the same direction operation button again when the blower unit 4 reaches the desired position. To set the movable end. As described above, the movable end can be set in any direction, and the swing range of the blower unit 4 can be set. When the swing range is set, the blower unit 4 swings within the swing range. I do.

  The direction operation button is pushed and operated to swing the air blowing unit 4. The air blowing unit 4 reaches one of the left end 54, right end 55, upper end 56, and lower end 57 without the same direction operation button being pushed again. In this case, the reached end is set as the movable end. In addition, when a different direction operation button is pushed after the direction operation button is pushed and the air blower 4 is swung, the direction corresponding to the direction operation button that is pushed later is changed. The air blower 4 starts a swinging motion. Therefore, an arbitrary movable end is set when the same direction operation button is pressed twice in succession. In addition, the setting of the movable end of the air blower 4 can be set in any direction, up, down, left, and right as in the first embodiment, and can be set in any order from any direction.
