Typically software routines may be stored in memory. The software routine may also be stored or executed by another CPU (not shown), which may be located remotely from the present cleaning device.

Although the process according to the invention has been described as being executed by software routines, at least some of the processes of the invention may be performed by hardware. As such, the processes of the present invention may be implemented in software executed on a computer system, or in hardware such as an integrated circuit, or in combination of software and hardware.

On the other hand, the microbubble generating unit (100a) is made of ozone microbubble based on the action of the ozone gas and the washing water supplied from the ozone gas supply unit 225, and then the washing water containing the ozone microbubble is cleaned in the cabinet 210. It is provided to the space 210a. According to the present embodiment, the micro bubble generating unit 100a is disposed in series on the branch line 230 so as to easily clean the medical container, and is preferably accelerated to the cleaning space 210a. Referring to FIG. 1, the microbubble generating unit 100a is shown to be supplied to the lower and lower ends of the cleaning space 210a. However, the present invention is not limited thereto. For example, the ozone microbubble generated from the microbubble generating unit 100a may be disposed to facilitate physical cleaning of the medical device. To this end, the microbubble generating unit 100a may be disposed so that the ozone microbubble is concentrated in a portion where the medical device is placed.

The micro bubble generating unit 100a will be described with reference to FIGS. 2, 3A, and 3B as follows. As shown in these figures, the microbubble generating unit (100a) has a device body (110a), and a rotation guide guide portion 130a provided in the device body (110a).

The device body 110a is a part which forms an appearance in the micro bubble generating unit 100a. It may be a plastic injection molding of transparent or translucent material, but need not be so.

The apparatus main body 110a has an air inlet 111a through which air as ozone gas is introduced, a water inlet 113a through which water as washing water is introduced at a position different from the air inlet 111a, and introduced air. The water discharge unit 115a through which the washing water containing the ozone microbubble is discharged by the interaction between water and water is provided. Here, the water flowing into the water inlet 113a may be washing water or water provided separately.

The device body 110a may have a cylindrical shape having the same cross-sectional area in all the sections except for the inner wall surface on which the air inlet 111a and the water outlet 115a are formed. In such a structure, the air inlet 111a and the water outlet 115a may be disposed to face each other at both ends of the apparatus body 110a, as shown in FIG. 3B.

As such, the air inlet 111a and the water outlet 115a are disposed opposite to each other at both ends of the apparatus main body 110a, thereby destroying (colliding) the introduced ozone singer to form an ozone microbubble, and then discharging it. This is preferred because it can proceed organically, but need not necessarily be. That is, if necessary, the air inlet 111a and the water outlet 115a and the water inlet 113a may be disposed at different positions from those in the drawing.

2 and 3A, the air inlet 111a is in the form of a hole, but since the air inlet 111a is an exemplary configuration, the air inlet 111a is not limited to the shape of a hole. Meanwhile, a separate connector (not shown) may be provided in the air inlet 111a as in the water inlet 113a. That is, the water inlet 113a is provided with a water supply connector 116a for supplying water to the water inlet 113a. The screw portion 117a is formed in the connector 116a for water supply.

In some sections of the inner wall surface of the water discharge unit 115a, an extended inclined surface 118a is formed in which a cross-sectional area of the water discharge unit 115a is gradually expanded. Thus, the expansion inclined surface 118a is formed in the water discharge portion 115a, so that the flow of the discharged water can be induced more quickly based on the Bernoulli method, which is a correlation between the cross-sectional area and the velocity of the fluid, thereby generating microbubbles. It can work advantageously.

The rotation guide unit 130a guides the rotation of the water introduced into the apparatus main body 110a through the water inlet 113a and guides it toward the air introduced through the air inlet 111a while strongly turning the water. Do it.

The rotation guide unit 130a may be separately manufactured and coupled to a corresponding position in the apparatus main body 110a. However, the injection guide unit 130a may be integrally manufactured when the apparatus main body 110a is manufactured. .

On the other hand, water collides toward the air to make the air remaining in the air, such as ozone gas, into a micro bubble, which is an ultra-fine bubble, but in order to increase the efficiency, the air flows into the apparatus main body 110a rapidly and also collides with the air. It is desirable to have a faster flow of water. In addition, the rotational (or swinging) method of water impinging on the air can be expected to improve efficiency. To this end, the rotation guide unit 130a is provided.

The rotation guide unit 130a is disposed along an imaginary line connecting the air inlet 111a and the water outlet 115a while allowing water flow from the water inlet 113a to the water outlet 115a. It includes a plurality of guide walls (140a, 150b).

The plurality of guide walls 140a and 150b include a first guide wall 140a and a second guide wall 150a disposed radially outward of the first guide wall 140a. Both the first guide wall 140a and the second guide wall 150a are provided as pipe-shaped tubular bodies.

One end of the first guide wall 140a is fixed to an inner wall surface of one side of the apparatus body 110a in which the water discharge unit 115a is formed while the one end thereof surrounds the water discharge unit 115a and the other end thereof is an air inlet 111a. ) Is spaced apart from the other inner wall surface of the device body (110a) formed.

The second guide wall 150a is disposed on the radially outer side of the first guide wall 140a to form a spaced gap between the first guide wall 140a and one end thereof with an air inlet 111a. It is fixed to the other inner wall surface of the main body (110a), the other end is spaced apart from one inner wall surface of the device body (110a) is formed water outlet (115a).

Referring to the action of the micro bubble generating unit (100a) having such a configuration, first, ozone gas is introduced into the apparatus main body (110a) through the air inlet (111a), the washing water through the water inlet (113a) the apparatus main body ( Flows into 110a). The introduced washing water is rotated due to the rotation guide unit 130a including the first guide wall 140a and the second guide wall 150a, and forms a flow as shown by the arrow of FIG. It collides rapidly and efficiently with the ozone gas entering through 111a), thereby effectively generating a large number of ozone microbubbles. As described above, the generated ozone microbubble is provided to the cleaning space 210a of the cabinet 210 together with the washing water.

Thus, the washing water containing ozone microbubble is provided to the washing space 210a, and the washing water from the washing water spray nozzle 223 and ultraviolet rays are irradiated from the ultraviolet lamp 252 and thus, inside the washing space 210a. The medical device may be sterilized.

As such, according to the present embodiment, the cleaning and sterilizing effect on the medical device can be significantly improved than before.

Various modifications to the microbubble generating unit

On the other hand, the above-described micro bubble generating unit (100a) may be variously modified as shown in Figures 4 to 10b out of the structure shown in Figures 1 to 3c.

Hereinafter, various modifications of the micro bubble generating units 100b to 100h will be described with reference to FIGS. 4 to 10B. Reference numerals in the following modifications are to use a method that gives the lowercase letters in the tail different, duplicate description is omitted.

4 is a cross-sectional view according to a second modification of the micro bubble generating unit.

The microbubble generating unit 100b according to the second modified example shown in this figure is the same in structure as the microbubble generating unit 100a of the first modified example. In other words, the rotation guidance unit 130b is the same as the first modified example in that it includes two first and second guide walls 140b and 150b.

4, the inner wall surfaces of the first and second guide walls 140b and 150b form inclined surfaces 141b and 151b whose cross-sectional area gradually decreases with respect to the direction in which water flows. It is different from the first modification.

As shown in FIG. 4, when the inclined surfaces 141b and 151b are formed on the inner wall surfaces of the first and second guide walls 140b and 150b, the flow of water discharged to the water discharge unit 115b by the inclined surfaces 141b and 151b may be faster. Can be. As a result, the flow and velocity of water can be increased to collide with air more quickly and more strongly, thereby increasing the amount of microbubbles generated.

Meanwhile, the microbubble generating unit 100b according to the second modified example is further provided with a porous air guide member 170b in the air inlet 111b. Porous air guide member 170b is formed with a number of fine pores (holes) on the surface, when the general air passes through the porous air guide member 170b, the size of the air particles is primarily reduced after the fine particles Since it may be introduced into the device body (110b) it may be more advantageous for generating micro bubbles.

In addition, when the porous air guide member 170b is employed, it is possible to prevent unnecessary consumption of air and to induce the inflow rate of air quickly, thereby increasing the efficiency of microbubble generation. .

In summary, in the present modified example, the porous air guide member 170b is used to maintain a small particle size of the incoming air in advance, thereby forming a rotating flow rate to increase the flow velocity at the inner wall instead of at the center region of the conduit. By doing so, it is possible to generate microbubbles of more effectively and finer size.

In the case of FIG. 4, the porous air guide member 170b is formed of a cylindrical pipe having a plurality of fine pores formed on a surface thereof, and one end thereof is coupled to the air inlet 111b but the free end thereof has a first end. It is arranged to partially enter into the guide wall 140b.

This is because when the flow rate is faster than the same flow rate, the incoming air and water collide more quickly, so the size of the bubble is generally smaller, and the water flowing in the rotation type is much better than the flow rate in the inner wall. It is advantageous to generate a micro bubble, in particular, if the length of the porous air guide member 170b as shown in Figure 4 is long so that the free end is arranged to enter a portion of the inside of the first guide wall 140b porous air guide member 170b The inflow of air provided from the side can be increased in various places, thereby increasing the amount of micro bubbles generated per unit time.

5 is a cross-sectional view according to a third modification of the micro bubble generating unit.

In the microbubble generating unit 100c according to the third modified example shown in this drawing, except that the porous air guide member 170c is formed of a conical pipe in which a plurality of fine pores are formed on a surface thereof. Is not different from the second modification.

6 is a cross-sectional view according to a fourth modified example of the microbubble generating unit.

In the microbubble generating unit 100d according to the fourth modified example shown in this drawing, both the apparatus main body 110d and the first and second guide walls 140d and 150d are provided as hollow bodies through which air can flow. It has a structure in which a plurality of fine pore holes (145d) is formed on the inner wall surface of the first guide wall (140d).

In addition, the porous air guide member 170d has a conical structure for introducing air into the inner space of the first guide wall 140d including the inside of the device body 110d.

In such a structure, since the air flowing from the porous air guide member 170d collides with the rotatable water flowing along two paths as shown by the arrow, it generates a larger amount of micro bubbles per unit time or unit size. It is advantageous.

7 is a sectional view according to a fifth modification of the microbubble generating unit.

The microbubble generating unit 100e according to the fifth modified example shown in this drawing is the same as the second modified example, but the collision type nozzle part 300e having the collision member 311 in the water discharge part 115e region. The difference is that is more concatenated.

The impingement nozzle unit 300e serves to double the generation of fine bubbles by colliding an admixture in which water and microbubbles are mixed through the water discharge unit 115e.

Referring to the collision nozzle unit 300e, the collision nozzle unit 300e sequentially includes the first diffusion unit 307, the first extension unit 309, and the collision member 311 in the direction of the arrow through which the air flows. , A second diffusion part 313 and a second extension part 315.

The first diffusion part 307 receives an airflow mixed with water and microbubbles from the water discharge part 115t and flows out to the first extension part 309. The first diffusion part 307 includes an inflow end 303 for receiving an airflow and an outlet end 305 for outflowing the airflow. It is formed narrower than the outlet end 305 of the inlet end 303. The diameter of the outlet end 305 is also formed to be narrower than the diameter of the water outlet 115e. In addition, the area of the first diffusion part 307 of the collision type nozzle part 300e has a structure in which the diameter gradually increases from the inlet end 303 to the outlet end 305.

The first extension part 309 is formed larger than the diameter of the outlet end 305 (discontinuously large) but flows the airflow while maintaining the same diameter for a predetermined section. Since the collision member 311 is provided in the region of the first extension portion 309, the adhering body collides with the collision member 311 while passing toward the first extension portion 309 through the first diffusion portion 307.

In other words, the air flowing through the first diffusion part 307 is subjected to a lot of pressure because the flow path of the first diffusion part 307 is narrow. In this state, the first extension part having a larger diameter, that is, a wider width, is provided. When 309 is reached, since the pressure suddenly weakens and collides with the collision member 311, fine bubbles may be generated.

As described above, the collision member 311 is disposed in the region of the first extension portion 309 and serves to generate fine bubbles as the air collides with each other. In the present modification, the collision member 311 is provided with a plate-like body having a large surface area, and is fixed to the inner wall surface of the collision nozzle part 300t by the trivet leg 312. Such a collision member 311 is not necessary to be limited in shape because it is sufficient if the structure that the air can collide.

Water containing the fine bubbles generated by hitting the collision member 311 is discharged through the second diffusion portion 313 and the second extension portion 315. In this case, although the second diffusion part 313 and the second extension part 315 may be omitted in construction, when the second diffusion part 313 and the second extension part 315 are provided, more fine bubbles are provided. It is advantageous in that it can be made.

The second diffusion part 313 is provided in the same manner as the structure of the first diffusion part 307. That is, the diameter of the first bubble 309 gradually increases from the diameter of the first extension portion 309 to the rearward direction with respect to the direction in which the water containing the fine bubbles flows.

The second extension part 315 is connected to the second diffusion part 313 so that the predetermined length section maintains the largest diameter of the second diffusion part 313.

When the collision type nozzle part 300e having such a structure is applied, the air flowing through the first diffusion part 307 receives a lot of pressure because the flow path of the first diffusion part 307 is narrow, and in this state, the diameter is increased. As it reaches a larger, ie, wider, first extension portion 309 and impinges on the collision member 311, a finer bubble is created. The water in which the fine bubbles are formed in this manner may be formed into many fine bubbles while passing through the second diffusion part 313 and the second extension part 315.

8 is a sectional view according to a sixth modification of the microbubble generating unit.

The microbubble generating unit 100f according to the sixth modified example shown in this drawing includes an inclined portion connecting the first diffusion portion 307 and the first extension portion 309 in the collision type nozzle portion 300f. Most of the same as the microbubble generating unit 100e of the fifth modification except that 308 is further formed.

The inclined portion 308 is connected to the first extension portion 309 while gradually increasing in diameter at the outlet end 305 of the first diffusion portion 307. There is no harm in generating fine bubbles.

9 is a sectional view according to a seventh modification of the microbubble generating unit.

The microbubble generating unit 100g according to the seventh modified example shown in this figure is the same as the microbubble generating unit of the fifth modified example except that the porous air guide member 170g has a conical shape.

However, in the case of this modification, the structure of the collision nozzle part 300g, especially the collision member 411 of the collision nozzle part 300g differs from a 5th modification. Although the collision member 411 is schematically illustrated in FIG. 9, the shape of the collision member 411 shows a view in which the airflow body can have a larger portion, an area, and repeatedly collide. For example, it may be considered that the pinwheel shape is arranged in a plurality, it can be more advantageous to make a fine bubble because the collision of the airflow can be further deepened.

10A is a perspective view according to an eighth modification of the microbubble generating unit, and FIG. 10B is a cross-sectional view of FIG. 10A.

Unlike the above-described modified examples, the microbubble generating unit 100h according to the eighth modified example shown in these figures is provided with a water supply connector 116h 'on both sides of the apparatus main body 110h. The water flows through 113h '. When such a structure is applied, since the water supply to the inside of the apparatus main body 110h may proceed at various places, it may be more advantageous for generating micro bubbles.

On the other hand, in addition to the first modified example, and having the same structure as the second to eighth briefly described above, while having a simple and simple structure, it is possible not only to increase the amount of micro bubbles generated relative to the amount of water and air used. The particles can be kept even. Therefore, the microbubble may be widely used for various purposes in various fields, for example, in the field of cleaning medical instruments and / or the like, as in the present embodiment.

The embodiments described above are all exemplary and various modifications may be made without departing from the spirit of the present invention.

For example, all of the above-described modifications of the microbubble generating unit may be equipped with an anion generator. Mounting an anion generator can provide finer air particles, which may be more advantageous for generating microbubbles.

7 to 9, the impact nozzle part is illustrated as being coupled to the apparatus body, but the impact nozzle portion may be integrally formed with the apparatus body.

In addition, all of the above-described modifications have been described as injecting water into the water inlet and air into the air inlet, but injecting water and air into the water inlet, and injecting air into the air inlet. It would also be possible. In addition, the portion to which water is supplied may be two or three or more places as shown in FIGS. 10A and 10B.

On the other hand, the micro-bubble generating unit described above may not only generate micro-sized bubbles, but also micro-sized bubbles smaller than the micro size. For example, the microbubble generating unit described above can generate microbubbles and / or nanobubbles of microbubbles and does not exclude producing bubbles of smaller sizes. In addition, the term "micro bubble generating unit" used in the present specification and claims does not produce only "micro sized bubbles", but "micro sized bubbles" and / or "nano sized bubbles" and / or "nano sized." It should be interpreted as a unit that produces a bubble containing a "bubble of smaller size than a bubble of size."

As described above, the present invention is not limited to the described embodiments, and various modifications and changes can be made without departing from the spirit and scope of the present invention, which will be apparent to those skilled in the art. Therefore, such modifications or variations will have to be belong to the claims of the present invention.
