Abstract

PURPOSE:To control the feeding direction of wind, by controlling a receiver in the wind feed direction being set by a transmitter with respect to a swing control section based on a wind feeding direction command fed from the transmitter. CONSTITUTION:When a wind feeding direction switch 22 of a transmitter 15 is set to a desired direction, the wind feeding direction is transmitted to a signal decision circuit 10 in a receiver 9 so as to start a swing motor 3. When the vane is directed to the direction set by said switch 22 then the swing motor 3 is stopped, wind can be fed to desired direction. Since a function for commanding the wind feeding direction is provided, the wind can be fed to desired direction at any time.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a remotely controllable electric fan for household or commercial use.

BACKGROUND OF THE INVENTION Conventionally, this type of electric fan has had a configuration as shown in FIG. In FIG. 2, wind is generated by a blower section consisting of a blade 1 and a blower motor 2 that drives the blade 1. The blower motor 2 is a motor whose rotation speed can be changed. The oscillation control section 5 is mainly formed by the oscillation motor 3 and the crank mechanism 4 attached to the oscillation motor 3, and the direction of the wind generated by the blade 1 and the blower motor 2 is changed by the oscillation control section 5. The support body 6 supports the blade 1, the blower motor 2, and the swing control section 5. The transmitter 8 commands the start/stop of the swing motor 3 and the rotation speed of the blower motor 2, and the receiver 7 determines whether the command signal from the transmitter 8 is valid and starts/stops the swing motor 3. It is used to stop and change the rotational speed of the blower motor 2.

In the electric fan configured as described above, after the transmitter 8 instructs the receiver 7 to start the oscillating motor 3, the transmitter 8 sends a command to the receiver 7 at the moment when the blades 1 face in the desired direction. By commanding the swing motor 3 to stop, air is blown in a desired direction.

FIG. 3 is a circuit diagram of the electric fan shown in FIG. 2. The transmitter 8 includes a wind strength selector switch 2o and a swing switch 2.
The setting state of 1 is input to the transmission code generation circuit 34, and the signal generated by the transmission code generation circuit 34 and the signal generated by the carrier wave generation circuit 33 are modulated by the modulation circuit 32 to generate the infrared light emitting element 3.
The configuration is such that the voltage is applied to 1. On the other hand, the receiver 8 amplifies the signal captured by the infrared light receiving element 29 with the amplifier circuit 28,
After the filter circuit 27 selects the carrier frequency, the detection circuit 26 extracts the transmission code, and the signal discrimination circuit 25 discriminates the signal. Signal discrimination circuit 2
5 recognizes that a valid signal has arrived that instructs the start/stop of the swing motor 3 or changes the wind strength, that is, changes the rotation speed of the blower motor 2, and turns the swing motor 3 on or off or blows the air. The rotation speed of the motor 2 is switched.

Problems to be Solved by the Invention In such a conventional configuration, when efficiently blowing air from an electric fan to a place where people are present, it is difficult to detect when the direction of the wind is in the desired direction. There was the operational hassle of having to instruct the oscillating motor to stop at 3Ω.

The present invention is intended to solve these problems.It is possible to specify the direction of the wind directly from the transmitter, and to make the head oscillate around the specified direction, thereby blowing air over a certain range. The purpose is to provide electric fans.

Means for Solving the Problem In order to solve this problem, the present invention provides a blower section that generates wind, a swing control section that changes the direction of the air from the blower section, and a swing control section that includes the blower section and the swing control section. a transmitter for commanding the air blowing direction, wind direction change, and wind strength; and a transmitter that determines whether the command signal from this transmitter is valid and sets the air blowing direction and changes the wind direction. , which has a receiver that switches the wind strength.

Function: According to this configuration, the receiver blows air in the desired direction by controlling the swing control unit to blow air in the direction set by the transmitter based on the command of the air blowing direction from the transmitter. It happens.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIG. In the drawings, the same symbols are used for the same components as in the prior art, and the explanation thereof will be omitted. In the figure, the transmitter 16 inputs the setting states of the wind strength changeover switch 2o, the swing switch 21, and the air blowing direction switch 22 to the transmission code generation circuit 19, and the signal generated by the transmission code generation circuit 19 and the carrier wave generation circuit. 1
The signal generated in step 8 is modulated by a modulation circuit 17 and applied to the infrared light emitting element 16. On the other hand, in the receiver 9, the signal captured by the infrared light receiving element 14 is amplified by the amplifier circuit 13, the filter circuit 12 selects the carrier frequency, the detection circuit 11 extracts the transmitted sign, and the signal discrimination circuit 1
o is configured to discriminate the signal.

In the above configuration, first, when the blowing direction switch 22 of the transmitter 16 is set to a desired direction, the blowing direction switch 22
The air blowing direction set in step 2 is transmitted to the signal discrimination circuit 1o of the receiver 9, and the signal discrimination circuit 10 activates the swing control 3 to move the air in the direction set by the air blowing direction switch 22 as shown in FIG. By directing the shown blade 1 and stopping the oscillating motor 3, air can be blown in a desired direction.

Furthermore, when blowing air within a certain angle range around the set direction, the swing switch 21 of the transmitter 15
By pressing , a signal is transmitted to the signal discrimination circuit 1o of the receiver 9, and the signal discrimination circuit 10 starts the oscillating motor 3.
By reciprocating the direction of the blade 1 shown in FIG. 2 within a certain angle, air can be blown within a certain angular range around the direction set by the air blowing direction switch 22 of the transmitter 9. In order to realize these series of operations, the oscillating motor 3 needs to be capable of forward/reverse rotation and rotation angle control.

Note that changing the direction of the wind can also be achieved by installing a wind direction control board in front of the blade 1 and controlling the direction; in this case, the direction of this wind direction control board is changed instead of the swing motor 3. I would like to install a useless motor.

Effects of the Invention As is clear from the above description of the embodiments, the present invention is equipped with a function that can command the direction of air blowing, so that the transmitter can be operated by detecting when the wind is directed in the desired direction. Air can be blown in any desired direction at any time.
