Description

An ultrasonic cleansing device with a hydro-flux generating structure

The present invention relates to an ultrasonic cleaning device for cleaning various parts, tools, laboratory tools and household kitchen utensils by using ultrasonic vibration, and more specifically, a circulation part consisting of a circulation pump and a suction and discharge hose is connected to a water tank. The present invention relates to an ultrasonic washing apparatus having a water flow generating structure having a structure capable of improving the washing rate of a to-be-cleaned object by forming a water stream in the washing liquid in the tank.

In general, ultrasonic vibration generally refers to vibration waves of about 20,000 Hz or more, and is widely applied to various cleaning devices such as washing machines, welding machines, fish detectors, etc., and is also used for medical devices. Is expanding.

Among them, in the washing apparatus using ultrasonic waves, the process of washing by ultrasonic waves can be said to be composed of sequential generation of each phenomenon divided into cavitation, acceleration energy, and micro streaming.

The cavitation is a cavity that is visible to the bubble by the pressure applied to the liquid is generated and the generated cavity is destroyed by the pressing force to generate a very large pressure to drop the contaminants on the surface of the object to be cleaned It is a phenomenon. It is one of the phenomena widely used in industrial ultrasonic cleaners using ultrasonic vibrators with a frequency range of about 20 kHz to 100 kHz.

In addition, when the ultrasonic wave is generated in the washing solution, the particles of the washing solution are vibrated, and the acceleration generated at this time is relatively increased as the frequency of the corresponding ultrasonic wave is increased. If the operating frequency is increased to the MHz unit, relatively strong acceleration energy is generated, which is transmitted to the contaminants on the surface of the object to be washed, and the contaminants are shaken by the acceleration force and dropped. This acceleration energy is applied to cleaning semiconductors, LCDs, and the like, and has characteristics suitable for removing micro-contaminants of about 1 μm or less.

On the other hand, the straight stream refers to the flow of the fluid generated in the direction of the ultrasonic wave in accordance with the difference in the radial pressure, thereby generating a minute agitation near the surface to be cleaned, thereby adding the effect of the circulation of the cleaning liquid, transport of contaminants, etc. Can improve the cleaning efficiency. In practice, however, the generation of straight streams is very weak and it is difficult to expect a special stirring effect.

Accordingly, cavitation is used in the ultrasonic cleaner of the low frequency band (kHz band), and acceleration energy acts as the main cleaning mechanism in the ultrasonic cleaner of the high frequency band (MHz band).

Conventional ultrasonic cleaning apparatus is carried out in the same principle as shown in Figure 1, consists of a water tank (10) containing a washing liquid (or washing water) 40, and the ultrasonic vibrator 20 coupled to the lower surface In addition, when power is supplied to the ultrasonic vibrator 20, ultrasonic vibration is generated and transmitted to the washing liquid 40, and the object to be cleaned 30 is cleaned by cavitation and acceleration energy among the aforementioned phenomena. As the fine bubble rises along the height direction is to continuously price the object to be cleaned (30).

However, when the cleaning liquid 40 is used for a long time, the contaminants separated from the to-be-washed object 30 are contained in the wash liquid 40 to increase the contamination of the wash liquid itself, and thus, the washing rate of the to-be-washed object 30 is lowered. There is a problem. In order to overcome this, the regular replacement of the cleaning liquid is necessary, but the regular replacement of the cleaning liquid in the water-saving dimension of the cleaning liquid 40 is a long situation.

As such, as the repeated use of the washing liquid 40 once introduced into the water tank 10 is generalized, there may be a case of being more contaminated after washing. In order to overcome this problem, the cleaning solution 40 in the water tank 10 must be circulated or filtered to reduce the contamination of the cleaning solution 40. However, the conventional cleaning device does not have any device or structure installed for the above purpose. have.

In addition, it is evident that in each of the phenomena mentioned above, the straight stream generates a flow of the washing liquid 40 and contributes to the increase in the washing rate. However, since the formation of the straight stream is insufficient, it is difficult to improve the washing rate, so there is no problem in developing a different structure for this.

In the conventional washing apparatus, as described above, since only the ultrasonic vibrator 20 is coupled to the lower portion of the water tank 10, there is a problem in that there is no provision of any structure or device for generating a separate washing liquid 40 flow. In addition to cavitation and acceleration energy, there is a limit in the composition of the environment such as a straight stream that can be expected to improve the cleaning rate.

Therefore, the present invention has been devised in view of the above-described conventional problems, and the first object of the present invention is to generate water flow in the washing liquid in addition to the transmission of ultrasonic vibrations, thereby creating a water flow structure of the structure capable of realizing the washing rate of the cleaned object. It is to provide an ultrasonic cleaning device having a.

As shown in Figure 1 and 2, the ultrasonic cleaning device 1000, by combining the ultrasonic vibrator 200 in the lower portion of the water tank 100 to generate a fine bubble in the washing solution 3000 in the water tank 100 Device. Such a fine bubble may function to escape the foreign matter by hitting the surface of the wash object 2000 stored in the water tank 100, wherein the separated foreign matter functions as a contaminant that contaminates the washing solution 3000 itself. do.

In the present invention, two hoses penetrate two outer walls of one side of the water tank 100, and two hoses are connected thereto, and each of the hoses 410 and 420 is connected to the circulation pump 430, thereby forcing the washing liquid 3000. It has a structure that generates water flow by circulating. At this time, the suction filter 410b is installed at the inlet of the suction hose 410 so that the foreign matter in the suction liquid 3000 is filtered.

The washing apparatus 1000 is provided with a cylindrical water tank 100 and a plurality of ultrasonic vibrators 200 for delivering ultrasonic waves to the lower surface thereof, and one side wall of the water tank 100 includes the above washing liquid ( For circulation of 3000, a water flow generating means consisting of a circulation pump 430 and two hoses connected thereto is installed.

Here, the water tank 100 is a cylindrical container structure with an open top, made of stainless steel, and the washing solution 3000 is contained therein. In addition, four ultrasonic vibrators 200 are coupled to the lower surface of the water tank 100 so that when the power is supplied to each ultrasonic vibrator 200, ultrasonic vibration is transmitted to the cleaning liquid 3000. At this time, the ultrasonic vibrator 200 may be used by combining the lower surface area of the water tank 100 more.

Each of the ultrasonic vibrators 200 has a structure of a bolt-clamped Langevin type transducer, and includes vibration elements such as piezoelectric elements, electro-distortion elements, and magneto-distortion elements. The lower surface of the water tank 100 is coupled by bonding or fastening, and the driving circuit unit 300 is electrically connected to control the power supply. The driving circuit unit 300 is a structure of a microcomputer, and is provided to function to adjust the power applied to each of the ultrasonic vibrators 200 in the middle, so that the number of the objects to be cleaned 2000 is large or complicated in shape. Applying a large power ultimately controls the intensity of the ultrasound.

One side wall of the water tank 100 is formed with two through-holes in a height direction, and a suction hole 410a and a discharge hole 420a, which are made of rubber, are inserted into and coupled with each other. The inlet 410a is located below and relatively close to the bottom surface of the water tank 100, and the outlet 420a is provided with a predetermined height difference thereon.

The suction hose 410 and the discharge hose 420 are fitted to the suction port 410a and the discharge port 420a. The suction hose 410 is the inlet portion is fitted to the inlet 410a, unlike the discharge hose 420 is the outlet portion is fitted to the outlet 420a and are respectively installed perpendicular to the outer wall of the water tank (100) Structure. In addition, a circulation pump 430 is connected to an outlet portion of the suction hose 410 and an inlet portion of the discharge hose 420. If the circulation pump 430 operates, the washing liquid 3000 is sucked into the suction hose 410. Suction is discharged into the water tank 100 through the discharge hose 420, the foreign matter contained in the washing liquid 3000 can be collected by the suction force to the connection portion side of the suction hose 410, and thus the other tank The degree of contamination at places in (100) is relatively less.

At this time, the suction filter 410b is installed at the inlet side of the suction hose 410 in front of the suction port 410a on the inner wall surface of the water tank 100. The suction filter 410b has a mesh structure made of stainless steel, and surrounds the front of the suction port 410a so that foreign matters contained in the cleaning liquid 3000 sucked into the suction hose 410 are filtered. As a result, the foreign matter is filtered, and the washing water having a relatively low pollution level is supplied back to the water tank 100 through the discharge hose 420.

As seen from the water tank 100, the washing liquid 3000 is discharged downward and supplied to the upper portion, so that the water flow generating means rotates counterclockwise when viewed from the front of the water tank 100 in the state installed at the right side of the water tank 100. Water flow can occur.

In addition, a timer 500 is connected to the circulation pump 430, and the timer 500 is installed to periodically operate the circulation pump 430. If the ultrasonic cleaning is performed for about 1 hour, if the cycle of the timer 500 is designated as 10 minutes, the washing liquid 3000 is circulated once every 10 minutes.

The water flow generating means is stored as a separate housing 440 on one outer wall of the water tank 100, it is made of stainless steel like the water tank 100 is connected to the outer wall.

2 is a state diagram of use of the ultrasonic cleaning device. As shown in FIG. 2, in the ultrasonic cleaning apparatus 1000, when the kitchen utensils such as a cutlery, chopsticks, and utensils are washed as the object to be cleaned 2000, the outlet 420a is once inside the water tank 100. After the water is poured into the washing solution 3000 to a height of at least, the washing object 2000 is stored, and ultrasonic power is applied to the ultrasonic vibrator 200 by applying power.

At this time, if the timer 500 of the circulation pump 430 is designated as 10 minutes, the circulation pump 430 is operated once every 10 minutes to force the circulation of the washing liquid 3000 and generate water flow.

Since the foreign matter such as various food debris may be attached to the object to be cleaned 2000 as described above, when ultrasonic vibration is transmitted to the washing liquid 3000, fine bubbles are generated and the foreign material is priced and separated. At this time, when the circulating pump 430 is operated, the separated foreign matter is sucked through the suction port 410a and the suction hose 410 and discharged through the discharge hose 420 and the discharge port 420a to generate water flow in the water tank 100. do. As a result of such water flow, the foreign matter release rate on the surface of the object to be cleaned 2000 may be increased.

In addition, since the suction filter 410b is installed in front of the suction port 410a, the contamination of the washing solution 3000 is reduced by the filtration of the suction filter 410b, and thus, the washing solution 3000 having the less contamination level is the water tank 100. ), The cleaning rate of the to-be-cleaned material 2000 that is lowered due to the contamination of the washing solution 3000 itself may be improved.

3 is a block diagram of a washing apparatus according to a second embodiment of the present invention.

It is a structure.

Each of the hoses 410 and 420 is connected to the circulation pump 430 so that the washing solution 3000 in the water tank 100 sucked into the suction hose 410 during operation of the circulation pump 430 is discharged through the discharge hose 420. The water is supplied into the water tank 100, and thus, when viewed from the top of the water tank 100, the water flow is generated while being circulated perpendicularly to the height direction as a whole. This flow of water has a similar flow pattern to the eddy generated when water is drained from the sink, and the strongest water flow is generated at the height at which the hoses 410 and 420 are connected and becomes smaller as it goes down. Generates a laminar flow with velocity.

Accordingly, when washing the object to be washed (2000), made of plastic or wood, the hoses (410, 420) are installed relatively high, and the object is made of metal with high specific gravity than water. In the case of 2000, the installation positions of the hoses 410 and 420 may be changed according to the type of the object to be cleaned 2000, such as relatively low heights of the hoses 410 and 420.

In addition, a plurality of circulation pumps 430 may be disposed along the outer wall of the water tank 100, and a structure in which each hose 410 and 420 is connected to have a height difference, and a structure in which each hose 410 and 420 are connected at the same height may be used in combination. Of course. In addition to the side wall surface of the water tank 100, it is also possible to use a structure in which each of the hoses (410, 420) is installed with the ultrasonic vibrator 200 interposed between the lower surface on which the ultrasonic vibrator 200 is installed.

In addition, the water tank 100 mentioned in the present invention, in addition to being used for washing kitchen utensils, varies in size depending on the type, size, and shape of the object to be cleaned 2000, and an ultrasonic vibrator of a higher frequency band (200) can be used to wash a large number of mechanical parts and tools, and electronic parts such as semiconductors and LCD panels, and it can be selected from polygonal shapes such as triangular and square, each corner being curved so that there are no angled parts other than cylindrical shape. Can be used.

The suction filter 410b may be used by changing to a structure that is fitted to remove foreign substances caught while being filtered for a long time in addition to being fixed to the inner wall surface of the water tank 100 at a corresponding position of the suction port 410a.

As the foreign matter release rate of the surface of the object to be cleaned increases, there is a characteristic that the cleaning rate can be further increased.

In addition, the hole is formed in the side wall of the water tank already installed, and each hose is connected to the existing ultrasonic cleaning device has the advantage that can be easily installed and used.
