Figure 1 is a schematic view of a non-contact controlled air flow machine in accordance with a preferred embodiment of the present invention. Referring to FIG. 1 , the non-contact control air flow machine is an electric fan in this embodiment. The electric fan includes an air flow machine housing 100 , a fan body 102 , an operation panel device 103 , a control circuit 104 , The special wavelength light emitting device 108, the two-dimensional special wavelength light sensor 109, and the lens 110. In the present embodiment, since the air flow machine is described by a vertical electric fan, the air flow machine housing 100 includes the base 120, the oscillating weight housing 121, and the support rod 122. The top surface of the base 120 is connected to the support rod 122, and the support rod 122 extends upwardly and is coupled to the swing head housing 121. The operation panel device 103 is disposed on the base 120 and has a plurality of settings in operation The operation button 107 on the plate device 103. The control circuit 104 is electrically connected to the fan body for controlling the operation of the fan body, such as the fan speed or whether the head is swung.

The special wavelength light emitting device 108 is disposed in the outer airflow casing 100 to emit a special wavelength of light (for example, infrared or other wavelengths of light). The lens 110 is also disposed on the outer airflow casing 100 and disposed on the receiving surface of the two-dimensional special-wavelength light sensor 109 to receive a specific wavelength of light within a specific range.

When the user wants to operate the electric fan, the operation button 107 on the control panel 103 can be directly contacted to control the wind speed and the swinging head of the electric fan. However, in the case where the user is far from the electric fan or the environment is too dim, the user cannot easily access the operation button 107. In the present embodiment, the user can choose to use the gesture control to control the electric fan, and there is no need to directly contact the conventional operation button 107. Hereinafter, in order to facilitate the description of the electric fan of the present embodiment, it is assumed that the special-wavelength light-emitting device 108 emits an infrared ray, and the two-dimensional special-wavelength photo sensor 109 is used to sense the infrared ray. When the user is within the range of the electric fan gesture sensing, the infrared light is reflected back by the user and received by the lens 110. The two-dimensional special wavelength light sensor 109 will sense the infrared light received by the lens 110 to detect a two-dimensional image.

In general, the two-dimensional special-wavelength photo sensor 109 is, for example, an array of a photosensitive element, a CMOS image sensor, a CMOS image sensor, or other photosensitive elements. this The photosensitive element array has MxN pixels, and cooperates with a miniature camera or camera (that is, the lens 110) to continuously capture external images and transmit them to the control circuit 104. The control circuit 104 determines the direction in which the hand moves, the angle of the movement, and even the shape of the hand, and the number of times the hand moves within a predetermined time, based on the received continuous image. In addition, the special wavelength light emitting device 108 is, for example, an additional designated light source, similar to the function of the fill light, for illuminating the user's hand, and the lens and the internal two-dimensional sensing element are captured by the infrared light reflected by the hand. image. In this embodiment, the lens can be filtered by means of a coating to avoid visible light from interfering with the two-dimensional sensor, and the two-dimensional sensor will not misjudge the image due to interference of visible light.

FIG. 2 is a schematic view showing the position and sensing range of the airflow lens of the present invention. Referring to FIG. 2, in the embodiment of FIG. 2, the lens 110 is disposed, for example, on the base 120 of the electric fan. Therefore, the lens 110 is disposed on the base of the electric fan, and the lens 110 can receive about 45 degrees from the horizontal plane. An image with a 90 degree angle. Therefore, when the user stands in front of the electric fan and the hand is extended, the lens 110 just captures the image of the user's hand to determine the user's control gesture command. For example, if the user's hand is swung left to right, it indicates an instruction to speed up the fan speed. Or, in a short period of time (for example, within two seconds), the user quickly swivels from left to right twice, indicating that the electric fan is to open the swing head. In addition, the above gesture may also be, for example, right swing to left, top to bottom or bottom to top, etc., so the gesture of the present invention is not limited to the combination of the swing direction, the number of swings, and the swing order described above.

In addition, the above gesture control is to detect the wave of the hand. The direction, the number of times, and the combination are used as instructions for the determination of subsequent gesture commands. In a preferred embodiment of the present invention, the gesture control may also be used as a basis for determining the command by detecting the shape and motion of the hand. For example, a user inputs a different control command using a hand gesture that is stuck for a period of time (eg, scissors, stones, cloth, or a single finger, etc.). In addition to the instructions corresponding to the gestures, in addition to the above-mentioned switch of the electric fan oscillating head and the air volume of the electric fan, the present invention may also include the opening and closing of the electric fan, so the instructions corresponding to the new gesture control will be in accordance with the type and function of the air flow machine. Adjustment, so the instructions corresponding to the gesture control of the present invention are not limited to the above examples.

In the above gesture control process, in order to enable the user to know whether the electric fan determines the gesture command input at this time, the embodiment also cooperates with a mechanism for emitting a prompt sound. Therefore, the above electric fan further includes a speaker 112. The control circuit 104 drives the speaker 112 to emit different prompt sounds according to different gesture control commands input by the user. For example, the prompt tone includes a plurality of different pitches to match a plurality of different air volume levels, for example, the lowest air volume level corresponds to the pitch of the pitch Do, the second lowest air volume corresponds to the pitch of the pitch Re, and so on. . When the user inputs a gesture command for increasing the speed of the electric fan, the electric fan sends a corresponding tone according to the current level to be converted to the air volume level. In addition, when the user inputs, for example, an instruction to turn the swing head on or off, the electric fan emits a beeping sound, for example.
