Description

  The present invention relates to a swing device for a blower (such as a fan or a circulator) that electrically controls the swing motion of a blower.

  If the blower part of the blower is kept in one direction, the wind sent by the blower part goes first and spreads a little, but basically it is only around the narrow area covered by the area of the blower part. Since it simply flows in the direction, the range in which the user can hit the wind is narrow, and only a specific person can cool, and multiple people cannot cool simultaneously. Therefore, most blowers are provided with a swing device, and the blower of the blower is swung in a certain angle range so that the wind is spread over a certain angle range.

  As the blower provided with the swing device, for example, as shown in FIG. 4, the blower 100, the support body 102 that supports the blower part 100 from below, and the blower part 100 can be swung to the support body 102. A connecting member (not shown) that is connected to the head, a swinging mechanism (not shown) that swings and reverses the air blowing unit 100, and a control device 104 that controls the swinging mechanism is known. According to this blower, the air blower 100 can be swung in a certain angle range, and the wind can be widened and sent in a certain angle range.

  By the way, such a blower operates the remote controller 106 to input and set the swing angle information stored in the control device 104 as desired angle information. However, even if the user assumes a desired angle for swinging and reversing the air blowing unit 100, and the desired angle information is input and set to the control device 104 using the remote control based on this assumption, the air blowing unit 100 is actually used. When the head is swung, the reversal angle position (folding angle position) is often not the desired reversal angle position, and the reversal angle position of the blower unit 100 is assumed to be the reversal angle position assumed by using the remote controller 106. It is very difficult to set.

  In order to set the angle position at which the air blower 100 is swung to the desired angle position, the information about the angle position to be reversed is input to the control device 104 by trial and error while the air blower is operated and the air blower 100 is swung. The remote controller 106 must be operated to set the input many times. However, if this is done, it takes a considerable amount of time to input the angular position information to be reversed, which is very troublesome for the user.

  The problem to be solved by the present invention is to use the reversal angle position information in the control device in an operation to electrically input and set the reversal angle position information in the control device that controls the swinging motion of the blower. It is difficult to immediately set the reversal angle position information that the user likes.

  The present invention includes a swing mechanism that swings and swivels the blower unit on a support, an angular position detection device that detects an angular position of the blower unit, and a control device that controls the movement of the swing mechanism. The main feature of the blower head swinging device is that the blower is used as the control device.

  More specifically, the present invention is obtained by an angular position detection device that uses a blower unit of a blower as an operation unit for inputting reverse angle position information to a control device and moves in conjunction with the blower unit. The main feature is that the angle position information in the front direction of the blower is obtained from the angle position information, and the angle position information is used as the inverted angle position information in the control device.

  Here, the blower includes a swing mechanism that swings and swings the blower unit on the support, an angular position detection device that detects an angular position of the blower unit, and angular position information obtained by the angular position detection device. And a control device for controlling the movement of the swing mechanism.

  In addition, after turning the blower at a speed equal to or higher than a predetermined angular velocity, the angular position information in the front direction of the blower when the turning speed of the blower becomes equal to or lower than the angular velocity and a predetermined time has elapsed. It is good also as inversion angle position information of this ventilation part. Moreover, you may make it input and set to the control apparatus the angle position information of the front direction of this ventilation part as inversion angle position information of this ventilation part. In addition, in said description, although the angular position information of the front direction of this ventilation part is used, it is not limited to a front direction, You may use the angle information of arbitrary directions.

  Also, the old inversion angle position information Ara in the inversion angle position information held in the control device is rewritten to the new inversion angle position information Arb, and the new inversion angle position information Arb that has not been rewritten is obtained by the above operation. The current angle position information Acur may be rewritten.

  As the angular position detection device, any detection method such as a resistance position sensor, a potentiometer (variable resistor), a rotary encoder, a gyro, a resolver, a hall sensor, a photo interrupter, a photo reflector, or the like may be used. When the reversal angle position information in the control device is rewritten to the reversal angle position information obtained by the above operation, a sound may be emitted or the display may emit light or blink.

  The blower head swing device according to the present invention uses the blower portion of the blower as the swing angle setting operation portion, and the rotation direction of the blower portion is determined, and the angle in the front direction of the blower portion is set as the reversal angle. Therefore, the inversion angle has a one-to-one correspondence with the angle in the front direction of the blower, and therefore, the swing inversion angle position of the blower of the blower can be easily set to the inversion angle position that the user likes. There is an advantage.

FIG. 1 is an exploded perspective view of essential parts of an embodiment of a blower provided with a swing device according to the present invention. FIG. 2 is a block diagram of an embodiment of a blower provided with a swing device according to the present invention. FIG. 3 is a flowchart showing a control process in the control device of the embodiment of the blower provided with the swing device according to the present invention. FIG. 4 is an explanatory view showing an embodiment of a conventional blower provided with a swing device.

  The object of easily setting the reversal angle position of the blower portion of the blower to the reversal angle position desired by the user is realized with the minimum number of parts and without increasing the cost of the swinging device of the blower.

  FIG. 1 is an exploded perspective view of an essential part of an embodiment of a blower provided with a swing device according to the present invention, and FIG. 2 is a configuration diagram of an embodiment of a blower provided with a swing device according to the present invention. In these drawings, reference numeral 10 denotes a fan motor, and a blower fan 12 is coaxially attached to a rotating shaft of the fan motor 10. The blower unit is configured with the fan motor 10, the blower fan 12, and a fan guard (not shown) as main components.

  An upper connecting member 14a is attached to the rear portion of the fan motor 10, and the upper connecting member 14a is connected to the upper portion of the lower lower connecting member 14b so as to be swingable back and forth using a rotating shaft 14c. The lower connecting member 14b has a rotating shaft 16 extending downward, and the rotating shaft 16 is rotatably inserted into a vertical hole 18a formed at the center of a columnar portion of the lower support 18. The upper connecting member 14a and the lower connecting member 14b constitute the connecting member 14.

  A helical gear 20 as a central member is coaxially attached to the rotating shaft 16 with being sandwiched between the lower connecting member 14 b and the support 18. A screw gear (worm gear) 22 as a satellite member is connected to the helical gear 20, and a rotation shaft of a swing motor 24 is coaxially attached to the screw gear 22. A mounting piece 26 is provided below the lower connecting member 14 b and away from the rotary shaft 16, and a swinging motor 24 is mounted on the mounting piece 26.

  An angular position detection device 30 that detects the rotation angle position of the rotation shaft 16 and outputs the rotation angle position information to the control device 28 is attached to the tip of the rotation shaft 16. The control device 28 controls the rotation direction of the swing motor 24 based on information on the rotation angle position of the rotary shaft 16 detected by the angular position detection device 30 to control the swing rotation angle width of the blower fan 12. It is configured.

  The angular position detection device 30 is configured to detect the rotational angular position of the rotary shaft 16 as an electrical value and output the electrical value to the A / D converter 32 of the control device 28. For example, a resistance position sensor can be used as the angular position detection device 30, but the angular position detection device 30 is not limited to a resistance position sensor. Further, without using the angular position detection device 30, a method of relatively detecting the angle may be employed, for example, using the number of steps of the stepping motor, the number of FG pulses of the motor, or a rotary encoder.

  The A / D converter 32 is configured to convert the voltage value output from the angular position detection device 30 into a digital value and output this digital value to the current angle calculation means 34 of the control device 28. The A / D converter 32 may be an A / D converter 32 built in the control device 28 or an external A / D converter 32.

  The current angle calculation means 34 is configured to calculate and obtain the current angle position information Acur from the digital value output from the A / D converter 32, and to output the current angle position information Acur to the current angle information holding RAM 36. .

  The current angle information holding RAM 36 holds the current angle position information Acur obtained by the current angle calculation means 34 and uses the current angle position information Acur as a swing operation detecting means 38, an automatic swing / turnback angle setting means 40, and an automatic swing. It is configured to output to the control means 42.

  When the current angle position information Acur output from the current angle information holding RAM 36 suddenly changes at a rate of change of 5 degrees / sec or more, the swing operation detection means 38 detects the change as swing operation information, and this is detected. The swing operation information is output to the automatic swing / turnback angle setting means 40.

  The automatic swing-back angle setting means 40 automatically uses the current angle position information Acur output from the current angle information holding RAM 36 when the swing operation information output from the swing operation detection means 38 is maintained for one second or more. The swing back turn angle information Ara / Arb is set, and the set automatic swing turn back angle information Ara / Arb is output to the automatic swing back turn angle information holding RAM 44 and held in the automatic swing back turn angle information holding RAM 44. The old automatic swing-back angle information Ara / Arb is rewritten with new automatic swing-back angle information Ara / Arb.

  The automatic swing-back angle information holding RAM 44 outputs the held automatic swing-back angle information Ara / Arb to the automatic swing control means 42, and the automatic swing control means 42 is current angle position information of the current angle information holding RAM 36. Based on Acur and the automatic swing-back angle information Ara / Arb in the automatic swing-back angle information holding RAM 44, the swing motor 24 is controlled to automatically swing the blower of the blower.

  In addition to the above-described one, the blower includes a buzzer 46 that sounds a setting sound, an operation switch 48 that operates the device, and a display 50 that includes an LED that displays the state of the device. The types of the buzzer 46, the operation switch 48, and the display device 50 are not limited. The buzzer 46, the operation switch 48, and the display device 50 may not be provided. The control device 28 controls the swing motor 24, the buzzer 46, the operation switch 48, the display 50, and the fan motor 10 via the I / O.

  Next, a control process in the control device that controls the swing device according to the present invention will be described with reference to the flowchart of FIG.

  First, the control process in the control device in a state where the user of the blower does not newly set the folding angle of the blower, that is, in the state of steady operation in which the folding angle position has already been set will be described.

  The operation switch 48 of the blower is operated to cause the blower unit to start automatic swing operation. The angular position detection device 30 acquires the current angular position information Acur, and the swing operation detecting means 38 determines whether or not there is a sudden angle change with respect to the acquired current angular position information Acur. Since the blower is in steady operation and the user has not given a sudden change in angle to the blower, it is determined that there is no sudden change in angle, and the process proceeds to a determination as to whether or not a turn-back angle determination waiting state is present.

  The automatic turning angle determination waiting state is determined by the automatic swinging turning angle setting means 40. The turn-back angle determination waiting state starts when there is a sudden angle change in the blower, but the user does not give a sudden change in angle to the blower, and there is no sudden angle change in the blower, so the turn-back angle It is determined that the state is not in the waiting state for confirmation, and the automatic swing control mode is entered.

  In the automatic swing control mode, the automatic swing control means 42 determines whether or not the current angular position information Acur is between the reverse angle position information Ara and Arb, and if it is between the reverse angle position information Ara and Arb Returns to the acquisition of the current angular position information Acur. If the current angular position information Acur is not between the reverse angular position information Ara and Arb, the head motor 24 is rotated in the reverse direction to return to the acquisition of the current angular position information Acur. .

  Next, a control process in the control device when the swing angle position of the blower is newly set will be described.

  When newly setting the swing angle position of the blower unit, the user turns the blower unit by hand at a speed equal to or higher than a predetermined angular velocity, and stops the turn at an angular position where the user wants to turn back.

  During the operation of the blower, the current angle is constantly acquired by the angular position detection device 30, and the swing operation detecting means 38 determines whether or not the acquired current angle has an angle change exceeding a predetermined angular velocity. Yes. When the user turns the air blower abruptly by hand (e.g., the rate of change is 5 degrees / sec or more), the swing operation detecting means 38 determines that there is a sudden angle change, and the automatic swing-back angle setting means At 40, the turning angle determination waiting state is started.

  When the automatic swing-back turn angle setting means 40 starts the turn-back angle determination waiting state, the turn-back angle determination wait timer starts counting and returns to the acquisition of the current angle position information Acur.

  Whether or not there is a sudden angle change with respect to the acquired current angle position information Acur is determined again by the swing operation detecting means 38. When the user continues to turn the blower, the count of the reverse angle determination waiting timer is reset and the process returns to the acquisition of the current angle position information Acur. When the user stops turning the air blower at an angular position where the user desires to turn back, the swinging operation detecting means 38 determines that there is no sudden angle change, and then determines the return angle confirmation waiting state. At this stage, since the return angle determination waiting state is still started, the automatic swing back return angle setting means 40 determines that the return angle determination is in a standby state.

  When it is determined that the turn-back angle determination wait state is established, it is determined whether or not the turn-back angle determination wait timer has expired. If the return angle determination waiting state continues for 1 second or longer, it is determined that the return angle determination wait timer has expired.

  When the turn-back angle determination waiting timer expires, the turn-back angle in the automatic head turn-back angle information holding RAM 44 is updated. In other words, the reverse angle position information Ara / Arb held in the automatic swing-back angle information holding RAM 44 is rewritten to the reverse angle position information Arb / Acur, and the old reverse angle position information Ara is sequentially deleted.

  When the folding angle of the automatic swing folding angle information holding RAM 44 is updated, the folding angle determination waiting state ends, and the process returns to the acquisition of the current angle position information Acur. If the return angle determination waiting timer does not expire, for example, if the stationary state does not continue for 1 second or longer, the process returns to the acquisition of the current angle position information Acur.

  In the above description, it is determined that the current angular position information Acur has changed abruptly at a change rate of 5 degrees / sec or more. However, the change rate is not limited to this value and can be arbitrarily set. it can. In the above description, it is determined that the folding angle determination waiting timer has expired when the folding angle determination waiting state continues for 1 second or longer. However, the time for determining that the folding angle determination waiting timer has expired is 1 It is not limited to seconds, and can be set arbitrarily.

  The above explanation is an explanation of one embodiment of the present invention, and the present invention is not limited to these explanations. For example, when performing an operation of setting the turning angle information to the control device using the air blowing unit, the method of switching to the input operation is not limited to the above-described embodiment, and those skilled in the art can appropriately consider it. A possible method may be adopted.

  In the above embodiment, the air blower is swung in the horizontal direction, but a sensor and a motor are installed so that the air blower can be swung in the vertical direction. The position may be set.

  Further, the swing mechanism of the above embodiment is turned back at an arbitrary angle position, but the swing may be reversed at a predetermined swing angle position instead of an arbitrary angle position. For example, if the air blower is rotated 40 ° to 50 ° to the right or left, the head is reversed at ± 45 °, and if the air blower is moved 50 ° to 60 ° to the right or left, the head is reversed at ± 55 °. You may make it do. Further, for example, when the air blower that has been swung over at ± 40 ° is rotated right or left, it may be swung over at ± 50 °.

  Further, in the above embodiment, automatic swinging is performed around the intermediate angular position between the left and right folding angle positions set as input, but the input angular position, for example, the air blower is rotated 40 ° to the right. Automatic swing may be performed around the 40 ° angular position.

  Alternatively, the rotational speed at which the user of the blower rotates the blower may be stored in the control device, and automatic swinging may be performed at the rotational speed.

  In addition, for example, 0 ° to 20 ° is a strong operation, 20 ° to 30 ° is an air blow off, 30 ° to 90 ° is a weak operation, and the air blow intensity may be changed depending on the swing angle. The swing rotation speed of each section may be changed according to each section.

  In addition, the swing mechanism may be used to make settings other than the setting of the swing angle position, such as power ON / OFF and setting of the blowing intensity.

  The present invention can be applied to uses other than setting the swinging condition of the blower unit, for example, to switch the blower mode, by diversifying the method of switching the blower unit to a state where it can be used as input operation means.
