Description

Ultrasonic Cleaning System for Vehicles

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic cleaning apparatus for a vehicle, and in particular, while driving a vehicle, the operation switch provided inside the vehicle is turned on to generate ultrasonic waves from a vibrator coupled to the vehicle body panel, and to remove dirt such as dust from the vehicle body panel. An ultrasonic cleaning apparatus for a vehicle capable of cleaning a vehicle body panel.

In general, ultrasonic waves (supersonic) refers to waves having a frequency greater than 20 kHz which is an audible frequency as vibration or pressure waves generated in an elastic medium. Ultrasound can be in the form of longitudinal waves, such as sound waves traveling in the air, or in the form of shear waves or shear waves in solids. In addition, the Rayleigh wave of the ultrasonic wave propagates along a solid surface, and the lamb wave propagates along a thin rod and the cutting plane of the object.

Ultrasonic cleaning refers to a surface cleaning method that removes and degreases the dirt of the object by causing mechanical stirring in the cleaning solution. In other words, the ultrasonic cleaning is transmitted as a small density wave when ultrasonic waves with a frequency of 16 kHz or more pass through the liquid, whereby the liquid repeatedly expands and compresses, and uses cavitation and interfacial disturbances generated.

Ultrasonic cleaning is used to clean parts of complicated shape, the inside of parts, micro parts such as watches, electronic device parts or internal combustion engine parts that are difficult to clean by brush or jet classification.

On the other hand, the vehicle is generally washed with a wet car wash using the washing water, or to wash the vehicle body using a brush or brush.

However, the wet car wash has a problem of excessive use of washing water and space for washing the vehicle, and the car wash using a brush or a brush is difficult to use while driving the vehicle.

It is an object of the present invention to generate ultrasonic waves in a vehicle body panel through a switch operation inside the vehicle while the user does not use the conventional wet car wash to clean the exterior of the vehicle, such as dust adhered to the surface of the vehicle body panel. To provide an ultrasonic cleaning device for a vehicle designed to easily remove the.

A first aspect of the present invention for achieving the above object is an ultrasonic cleaning apparatus for a vehicle for removing dust and dirt on the surface of the vehicle body, the oscillator control means connected to the vehicle power source; An operation switch provided inside the vehicle to turn on / off the oscillator control means; An ultrasonic frequency oscillator supplied with power from the oscillator control means by turning on the operation switch; And an oscillator electrically connected to the ultrasonic frequency oscillator and receiving ultrasonic signals from the ultrasonic frequency oscillator to generate ultrasonic vibrations.

A second feature of the present invention is the first feature, wherein the vibrator is mounted in a groove inside the vehicle body panel.

According to a second aspect of the present invention, in the second aspect, the vibrator generates a vibration wave in a direction perpendicular to the vehicle body panel, and transmits the vibration wave along a side surface parallel to the vehicle body panel.

As described above, according to the ultrasonic cleaning apparatus for a vehicle according to the present invention, in order to clean the exterior of a vehicle, the user generates ultrasonic waves in the vehicle body panel through a switch operation inside the vehicle while driving without using a conventional wet car wash. The effect is that the contaminants such as dust attached to the surface of the body panel can be easily removed.

Briefly, the present invention relates to an ultrasonic cleaning apparatus for a vehicle. In particular, it allows a user to easily remove contaminants on the body panel while driving the vehicle without using wet cleaning using washing water.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

1 is a block diagram illustrating an ultrasonic cleaning apparatus according to an embodiment of the present invention.

As shown in FIG. 1, the ultrasonic cleaning apparatus according to an embodiment of the present invention includes an oscillator control means 3 connected to the vehicle power source 1. In this case, the vehicle power source 1 may be a battery mounted in a vehicle. The oscillator control means 3 is turned on / off by the operation switch 5 provided in the interior of the vehicle, the power supply to the ultrasonic frequency oscillator 7 by turning on the operation switch (5) do.

The ultrasonic frequency oscillator 7 receives electric power from the oscillator control means 3 and supplies an electronic signal for generating ultrasonic vibration to the vibrator 9. In this case, the ultrasonic frequency oscillator 7 may include an amplifier for amplifying the oscillated frequency. The vibrator 9 is coupled to a predetermined portion inside the vehicle body panel to generate vibration waves in a direction perpendicular to the vehicle body panel.

2 is a perspective view illustrating a vehicle in which an ultrasonic vibrator is installed in accordance with an embodiment of the present invention, and FIG. 3 is an enlarged cross-sectional view illustrating an installation state of the vibrator on the vehicle body by enlarging A of FIG. 2.

As shown in Figs. 2 and 3, the vibrator 9 is mounted in a groove provided in the interior of the vehicle body panels 13a, 13b, 13c. The vibrator 9 vibrates in a direction perpendicular to the vehicle body panels 13a, 13b, and 13c to generate vibration waves, and along the direction Tr parallel to the surfaces of the vehicle body panels 13a, 13b, and 13c. It propagates the vibration wave. Thus, the vibration wave degrades the adhesion of pollutants 17 such as dust adsorbed on the outside of the vehicle panels 13a, 13b, 13c, and the pollutants 17 are generated while the driver is driving the vehicle. Can be removed by the running wind.

In this case, the pollutant 17 can be more easily removed by the liquid discharged from the liquid jetting means (not shown) further provided in the vehicle body panels 13a, 13b, and 13c while driving the vehicle.

Next, an operation method of the dust removing apparatus for removing contaminants adsorbed on the vehicle panel will be described with reference to FIGS. 1 to 3.

As illustrated in FIGS. 1 to 3, when a driver or a vehicle occupant operates a manipulation switch 5 provided indoors while the vehicle is in operation, an ultrasonic frequency connected to the vehicle power source 1 is turned on. The oscillator 4 transmits an electronic signal capable of generating ultrasonic vibrations to the vibrator 9 formed in the groove inside the vehicle body panels 13a, 13b, and 13c. The vibrator 9 vibrates in a direction perpendicular to the vehicle body panels 13a, 13b, and 13c to generate vibration waves, and generates a direction Tr parallel to the surfaces of the vehicle body panels 13a, 13b, and 13c. Thus propagating the vibration wave.

Accordingly, the vibration wave degrades the adhesion of contaminants 17 such as dust adsorbed on the outside of the vehicle body panels 13a, 13b, and 13c, and the contaminants 17 are generated while the driver is driving the vehicle. It is removed by running wind. In this case, the pollutant 17 can be easily removed by the liquid discharged from the liquid ejection means (not shown) further provided in the vehicle body panels 13a, 13b, and 13c while driving the vehicle.
