Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a blower with an improved swing mechanism.

[Conventional technology]

FIG. 6 is a diagram showing a conventional blower shown in, for example, Japanese Utility Model Application Publication No. 58-173798. (3) is a motor part connected to this fixed part, (A) is a blade rotatably provided on this motor part, and ((5) is a circuit provided at the bottom of this blade. In the section, a receiving device (6) is installed, and control signals (to) from a separate transmitter M2 are used to receive start, stop, air volume adjustment, etc., and in relation to the circuit section (9), the blower (1 ) is operated.

A conventional blower is configured as described above, and has a motor section (3).
Power is input to the transmitter, and a control signal 8) is transmitted from the transmitter to the receiver (6), whereby the blower (1) is operated and the air volume is adjusted.

[Problem to be solved by the invention]

With conventional blowers like the one above, you can start them up and down by remote control.
For example, if a swing mechanism was added to the product body, there was a problem that the swing could not be controlled by remote control.

This invention was made to solve the problem,
The purpose is to obtain a blower whose swing can be controlled by remote control.

[Means to solve the problem]

The blower according to the present invention has a blower head equipped with blower blades that is rotatably mounted on a base, and includes a receiver provided on the base, a wireless transmitter that transmits data to the receiver, A microcomputer is provided which can arbitrarily change the air blowing direction of the blower head via the receiver in response to input from the wireless transmitter.

[Effect]

In this invention, the air blowing direction of the blower head can be changed by remote control.

(13) is a neck piece installed at the upper end of this instrument stand so that it can move up and down, and (14) is a swinging motor installed in this neck piece, which can be rotated in both forward and reverse directions using an AC power source, for example. Consists of what is possible. (15) is a joint projecting upward from this oscillating motor, and serves as a rotating portion (16), which is connected to the blower head, which will be described later. (17) is a center detection circuit installed in the part of the joint 1- that protrudes from the neckpiece (13), and is controlled based on the time from the center using, for example, an optical sensor, a Hall element, a contact point, etc. It is.

Furthermore, as shown in Fig. 2, the electrical configuration is as follows: (27) is the power supply, and (28) to (31) are the motors (20) that are turned ON and OFF.
(32) is a microcomputer, (33) is a power supply circuit for this microcomputer and other output circuits, (34) is a reset circuit, (35)
) is the clock generation circuit, (36) is the input key switch (
(not shown) and the like, and (37) is an output circuit, which is made up of, for example, an LED. (38) is a capacitor for the motor (20), (39) is a wireless transmitter that emits light to the receiver (12), and has a swing left switch (40) and a swing right switch (41), and further shown in the figure. Although not included, a rotation notch for the motor (20) and switches such as a timer are provided. In Fig. 4, TR is the time to swing the fan (II) to the right from the reference point, which is the center of the position, TL is the time to swing the fan to the left from the reference point, and t is the left swing switch ( 40) and the time during which the right swing switch (41) is pressed.

In the blower configured as above, the power source (27
) is input, the motor (20) is activated and the air blowing operation begins.Next, the rotation notch and timer of the motor (20) are arbitrarily set using the wireless transmitter (39) as shown in Figure 4. and if not set, the swing left switch (
40) is ON, the time during which the swing left switch (40) is ON is added to the time to swing the fan 0 to the left from the center of the position detected by the center detection circuit (17). Then, the swing range is moved to the left as shown in FIG.

In addition, even when the right swing switch (41) is turned on, the ON time of the right swing switch (old) is added to the time to swing right from the center of the position, and the range of swing to the right is increased. will be moved. On the other hand, the blower head (18
) is stopped, each of the above switches (40) and (41
) is turned on and the blowing m a R section (IB) is moved in each direction between the tails, the blowing direction can be changed, and the blowing action is performed by the above-mentioned processes. In this way, the air blowing direction can be arbitrarily changed using the receiver (12) and the wireless transmitter (39) using the microcomputer (32), and the center of swing can be changed without changing the swing angle. The conventional double swing mechanism is not required.

〔Effect of the invention〕

As explained above, the present invention includes a blower head equipped with blower blades that is rotatably mounted on a base, which includes a receiver provided on the base, and a wireless transmitter that transmits data to the receiver. By providing a microcomputer that can arbitrarily change the air blowing direction of the blower head via the receiver in response to input from the wireless transmitter, a blower that can easily control air blowing at hand is obtained. effective.
