Description

Ozone Water Low Temperature Washing Disinfector}

The present invention relates to a low-temperature washing and sterilizing device for ozone water, and more particularly, by installing a plurality of ultrasonic vibrators oscillating a short frequency in the 40 kHz band on the floor, front, back, left, and right sides in a washing tank containing ozone water, respectively, to cause cavitation of ultrasonic waves. It relates to an ozonated water low-temperature washing and disinfector that performs disinfection while easily removing foreign substances attached to objects to be washed in a washing tank by oxidizing power of OH radicals following decomposition of ozone water and cavitation.

In the case of medical devices and by-products, cleaning is performed after use. One example of such medical devices is a dental handpiece, which is a dental medical device that polishes and removes infected or damaged teeth. and powder, as well as various pathogenic microorganisms and viruses.

In general, since contaminants of handpieces such as saliva and blood may include various disease-causing factors such as AIDS or hepatitis, the contaminated handpieces may cause fatal infections to doctors and nurses who use them.

A conventional method of washing/disinfecting medical devices such as a used handpiece was to boil the medical device in boiling water or to use a high-temperature and high-pressure autoclave. However, this conventional method has a fatal disadvantage in that it takes too much time to clean/disinfect one medical device.

Considering the large number of patients visiting the dentist, the patient's waiting time for treatment is extended, which inevitably deteriorates the quality of medical service experienced by the patient. Failure to do so may result in the transmission of various disease-causing factors. In addition, in the case of handpieces, the above-described problem was conspicuous because of the high frequency of use among dental medical devices.

In addition, the conventional washing/disinfection method using high temperature and high pressure can damage medical devices such as handpieces to deteriorate their functions, and even when various disease-causing factors are inactivated through high temperature and high pressure, they remain inside the handpiece and other Since it can be transferred to a patient and help to propagate pathogenic microorganisms, an effective cleaning/disinfection method for medical devices such as handpieces is urgently required.

In this way, in general, after surgery or treatment, blood or living tissue is attached to various medical instruments such as medical tools, surgical scalpels, and endoscopes. Infectious pathogens are likely to be dormant among these deposits.

On the other hand, ozone has sterilizing power that can sterilize harmful viruses and bacteria in a short time of seconds, but does not have the risk or side effect of generating resistant bacteria like antibiotics. Research on its use is being actively conducted.

Therefore, there is an urgent need to improve a cleaning device capable of cleaning medical devices as well as various cleaning materials by using ozone having excellent sterilization and disinfection effects.

FIG. 3 is a schematic view of a washing tub according to an embodiment of the present invention, FIG. 4 is a plan view of FIG. 3 , FIG. 5 is a front view of FIG. 3 , and FIG. 6 is a side view of FIG. 3 .

Referring to the drawings, in the washing tub 300 according to an embodiment of the present invention, as described above, the ultrasonic vibration unit 400 is installed on five surfaces of the front, rear, left, right, and bottom surfaces of the washing tub 300, respectively. It is configured to oscillate ultrasonic waves toward the center of the washing tub 300.

The ultrasonic vibrator 400 includes at least one first ultrasonic vibrator 410 installed on the bottom surface of the washing tub 300 and oscillating ultrasonic waves upward, and installed on inner wall surfaces of both left and right sides of the washing tub, respectively. (300) At least one second ultrasonic vibrator 420 oscillating ultrasonic waves toward the center, and at least one third ultrasonic vibrator 430 installed on inner wall surfaces of both sides of the washing tub and oscillating ultrasonic waves toward the center of the washing tub. ) is composed of

The first ultrasonic vibrator 410, the second ultrasonic vibrator 420, and the third ultrasonic vibrator 430 may be formed in various ways according to the size of the washing tub 300, that is, width × length × height, but When the ultrasonic waves oscillated between adjacent ultrasonic oscillators interfere with each other, noise is generated due to impact, and the ultrasonic wave may not reach the object to be cleaned in a strong state due to the collision between them.

Therefore, in one embodiment of the present invention, the first ultrasonic vibrator 410, the second ultrasonic vibrator 420, and the third ultrasonic vibrator 430 are respectively the bottom surface of the washing tub, the inner wall surfaces on both sides of the left and right sides, and the front and rear surfaces. A plurality of doedoes are spaced apart from each other on both inner wall surfaces, and are arranged so that the ultrasonic vibrators are spaced at least 100 mm apart.

In addition, the ultrasonic vibrator 400 includes a control unit 440 that controls the operation of the first ultrasonic vibrator, the second ultrasonic vibrator, and the third ultrasonic vibrator. A first channel controller 441 that controls the operation of the vibrator 410, a second channel controller 442 that controls the operation of the second ultrasonic vibrator 420, and the third ultrasonic vibrator 430 ) It is composed of a third channel control unit 443 that performs operation control.

In this way, as the first, second and third channel controllers are configured to correspond to the first, second and third ultrasonic vibrators, operation can be individually controlled through the control unit 400 and the first channel The control unit, the second channel control unit, and the third channel control unit may be simultaneously operated or at least one may be operated alternately according to a set order.

Accordingly, it is possible to configure various washing control settings according to the characteristics of the object to be washed.

Meanwhile, the control unit 440 is configured to prevent damage to objects to be washed when operating at least one of the first channel control unit 441, the second channel control unit 442, and the third channel control unit 443. It can be configured so that continuous operation for more than a critical period of time is not performed.

That is, through the first channel control unit 441, the operation time can be set by repeating the process of maintaining the oscillation operation of the first ultrasonic vibrator 410 for 60 seconds, stopping it for 2 minutes, and then restarting it again three times. .

This critical time setting can be damaged by resonance when ultrasonic waves are oscillated for a long time, especially in the case of objects to be cleaned in the form of glass, if they are continuously exposed to ultrasonic waves for a certain period of time, so such a critical time setting may be required. there is.

On the other hand, in one embodiment of the present invention, it is preferable to set the oscillation ultrasonic band of the first ultrasonic vibrator 410, the second ultrasonic vibrator 420, and the third ultrasonic vibrator 430 to a band of 40 kHz among short frequencies, which Ultrasonic waves in the 40kHz band have a relatively larger guaranteed oscillation distance than those in the 20kHz, 24kHz, and 28kHz bands, and the oscillation direction is also oscillated almost linearly in a forward direction orthogonal to the vibrator plane of the ultrasonic transducer.

In the case of the 20kHz, 24kHz, and 28kHz bands, as the oscillation direction is oscillated radially by 15° in the left and right directions with respect to the forward direction orthogonal to the oscillator surface of the corresponding ultrasonic oscillator, ultrasonic interference with neighboring ultrasonic oscillators occurs. This results in increased noise and lowered cleaning efficiency.

Therefore, in one embodiment of the present invention, the oscillation ultrasonic band of the first ultrasonic oscillator 410, the second ultrasonic oscillator 420, and the third ultrasonic oscillator 430 is oscillated with ultrasonic waves of a 40 kHz band among short frequencies, and the corresponding ultrasonic oscillators It is configured so that the oscillation direction is made in the forward direction orthogonal to the vibrator surface of

In addition, in one embodiment of the present invention, the first ultrasonic vibrator 410 is located at 12 locations on the bottom surface of the washing tub 300, and the second ultrasonic vibrator 420 is located at 5 locations on the left and right inner wall surfaces of the washing tub 300, respectively. The third ultrasonic vibrator 430 is provided at three locations on the inner wall surface of the front and rear sides of the washing tub 300, respectively.

At this time, it is preferable to maintain a distance of at least 100 mm or more, preferably about 115 mm to 130 mm, between the ultrasonic vibrators.

If the interval between ultrasonic oscillators is greater than 130mm, the number of ultrasonic oscillators that can be installed for the size of the washing tank decreases, reducing the efficiency of removing foreign substances from the object to be cleaned. As a result of this, not only noise generation but also the effect of ultrasonic pressure applied to the object to be cleaned due to the impact between them is reduced.

In addition, the first, second, and third ultrasonic vibrators have 12 positions of the first ultrasonic vibrator 410 spaced apart from the left and right side edges of the bottom surface of the washing tub 300 at a predetermined interval, respectively, and are located at 5 positions each. , and are spaced apart at regular intervals before and after the drain discharge end (DR) formed on the center side of the bottom surface of the washing tub, but are spaced apart at regular intervals from the left and right side edges of the bottom surface of the washing tub 300, and are formed at 5 locations each It is formed between the vibrator and the first ultrasonic vibrator 410 at each of 12 places is configured to maintain a distance of 100 mm or more.

In addition, the second ultrasonic vibrator 420, among the first ultrasonic vibrators 410, is spaced apart at a predetermined interval from both left and right edges of the bottom surface of the washing tub 300, and is spaced apart at a predetermined interval from each of the five places to the left and right, and moves upward. In a state of being spaced apart at regular intervals, five locations are located on the left and right inner wall surfaces, respectively.

That is, if the longitudinal direction of the left and right inner wall surfaces is defined as the X axis and the longitudinal direction of the front and rear inner wall surfaces as the Y axis, the left and right rims of the bottom surface of the washing tub 300 of the first ultrasonic vibrator 410 The X-axis positions are formed identically by being spaced apart at a predetermined distance from each other, and each of the five locations on the left and right inner wall surfaces of the second ultrasonic vibrator 420 correspond to each other one-to-one.

In addition, the first ultrasonic vibrator 410 is spaced apart from the front and rear edges of the bottom surface of the washing tub 300, but is formed at the closest three places and the front and rear inner wall edges of the third ultrasonic vibrator 430, respectively. The locations correspond to each other on a one-to-one basis so that the Y-axis positions are identical.

In this way, the X-axis position or Y-axis position between the first ultrasonic oscillator 410 and the second ultrasonic oscillator 420 and between the first ultrasonic oscillator 410 and the third ultrasonic oscillator 430 is formed in a one-to-one correspondence. What is to be done is that when ultrasonic oscillators on the bottom, left, right, and front and rear sides simultaneously oscillate ultrasonic waves at a specific location of the object to be cleaned, the specific location of the object to be cleaned receives the most powerful ultrasonic impact effect, maximizing the efficiency of removing foreign substances. Because.

In this way, the plurality of ultrasonic oscillators of the first, second, and third ultrasonic oscillators 410, 420, and 430 correspond to each other and position the X-axis or Y-axis at the same location, so that ultrasonic waves are emitted simultaneously in various directions at a specific location in the washing tank. As it launches and strikes, the impact effect can be maximized.

Second and third channel control units are provided. In this embodiment, the second ultrasonic vibrator 420 and the third ultrasonic vibrator 430 separately operate and control the left and right sides and the front and rear sides, respectively. The control unit 442 consists of a left control unit 442a and a right control unit 442b, and the third channel control unit 443 consists of a front side control unit 443a and a rear side control unit 443b. .

Accordingly, the control unit 440 includes the first channel control unit 441, the left control unit 442a of the second channel control unit, the right control unit 442b, and the front side control unit 443a of the third channel control unit. and the rear side control unit 443b may be simultaneously operated or at least one may be operated alternately according to a set order.

That is, it is possible to individually control the operation of each of the five surfaces of the ultrasonic vibrator.

Accordingly, more precise ultrasonic oscillation can be performed. If the control unit 440 can detect the size, shape, current accommodation position, etc. of the object to be washed by a separate sensor means, it corresponds to the current state and is required according to the setting. Directional ultrasonic oscillation can be performed precisely.

In this way, when operation control is performed on each of the five surfaces, the interval between the ultrasonic vibrators can be narrower, so that the foreign matter removal efficiency and the generation rate of OH radicals can be further increased according to ultrasonic oscillation.
