Secondarily, heating is performed to provide a sterilization space to sterilize the handpiece The handpiece refers mainly to a dental handpiece in the embodiment of the present invention, but may include various types of devices that may be exposed to bacteria such as a surgical instrument, an endoscope apparatus, and a dental apparatus.

It should be noted that the water body described here may basically mean distilled water, but it does not exclude chemical fluids or various types of solutions.

FIG. 2 is a perspective view of the high-efficiency handpiece sterilizer of the present invention, and FIG. 3 is a longitudinal sectional view thereof.

It is preferable that the casing 1100 is formed in a cylindrical shape which can be sealed as a whole, but it is not limited to the illustrated form. The casing 1100 may be made of a material which is resistant to high temperatures and pressures inside, and a steam generating part 2000 is coupled to a lower side and a predetermined opening is formed on an upper side.

The opening and closing part 1300 is connected to the upper end of the casing 1100 by a hinge part 1320 so that the opening and closing part 1300 can be opened and closed It will be possible. The opening / closing part 1300 may be composed of an upper opening / closing handle 1310 and an opening / closing door 1330 which covers the opening. The opening and closing part 1300 may include hermetic means such as a sealing ring and locking means (not shown) to fix the closed state so that the casing 1100 can be kept sealed. The hermetic means and the locking means are omitted from the redundant description because various known devices can be applied.

The outside of the casing 1100 can communicate with a predetermined external device including a charging unit 1420 connected to a pump or a tank to inject a water body into the interior of the casing 1100 and a discharge unit 1410 through which steam is discharged. Related will be described later.

A sensing portion 1510 connected to the inside of the casing 1100 and capable of accurately measuring the temperature and / or pressure of the sterilizing space 1110 may be coupled to the casing 1100.

The inside of the casing 1100 is formed in a substantially closed form, and the handpiece 100 can be pulled out from the upper opening. However, in the case of the conventional art, when the handpiece is to be inserted into or withdrawn from a predetermined chamber, it is necessary to perform an operation of gripping and pulling the handpiece separately. This process is cumbersome and may cause injury. Particularly, since there is a possibility of additional contamination in the inlet / outlet process, in the present invention, a mounting part 3000 capable of mounting the handpiece 100 can be inserted into and withdrawn from the casing 1100 . The embodiment of the mounting portion 3000 will be described later.

The upper space of the casing 1100 in which the mounting portion 3000 is disposed is defined as a sterilizing space 1110. The sterilizing space 1110 may be divided at the position of the support portion 1020 formed inside the casing 1100 and the support portion 1020 may perform the function of supporting the bottom portion of the attachment portion 3000 . The support portion 1020 may be formed in a disc shape or a ring shape, a protrusion shape protruding from the inner wall of the casing 1100, and the like.

The steam flowing into the side of the stationary part 3000 is supplied as superheated steam as described above, and such superheated steam can be generated below the stationary part 3000.

To this end, the steam generating unit 2000 is disposed at the bottom of the casing 1100 and functions to generate steam in the course of the primary heating by receiving the water body from the outside through the input unit 1420. The steam generated from the steam generating unit 2000 may be secondarily heated from the heating unit 2010 while being stood in the steam collecting space 1121 and converted into super heated steam and supplied to the mounting unit 3000. For reference, it is preferable that the heating unit 2010 is fastened in a manner to be inserted from the lower side of the steam generating unit 2000 as shown in the figure.

At this time, when a plurality of handpieces 100 are disposed in the mounting part 3000 or a handpiece 100 having a relatively large volume is disposed, steam may not be supplied uniformly. Therefore, at the bottom of the mounting part 3000, The distribution space 1122 can be formed above the steam trapping space 1121 so that the steam can be temporarily distributed and evenly distributed.

For this purpose, a partition 1010 is formed below the support portion 1020 so as to cross the space. A predetermined flow passage 1123 may be formed in the partition 1010 so that the heating portion 2010 can pass through the center portion of the partition 1010. The flow passage 1123 may be a simple hole But it is preferable that it is formed in a cylindrical shape extending from the center of the disk-shaped body to the bottom as shown in the figure so as to absorb the heat of the heating unit 2010 as much as possible during the circulation process.

In order to maximize the spatial advantage, the heating unit 2010 may be disposed in such a manner that the heating unit 2010 is coupled to the center of the steam generating unit 2000, and such fixing structure will be described later. The heating unit 2010 can effectively sterilize the steam generated from the steam generating unit 2000 by using a superheated steam as quickly as possible. The heating unit 2010 includes a steam trapping space 1121, It may be desirable to be disposed through the dispensing space 1122.

The bracket portion 1200 may be disposed on the outer surface of the casing 1100 to minimize heat transfer while being supported by an external structure. The shape and type of the bracket portion 1200 are not limited to the illustrated embodiment .

4 is a perspective view for explaining an embodiment of a steam generator in the high-efficiency handpiece sterilizer of the present invention.

In the embodiment of the present invention, the steam generator 2000 is disposed at the bottom of the casing 1100, and the steam generator 2000 is formed in a disc shape to maximize spatial efficiency.

The water body is introduced into the side of the steam generating part 2000 through the input part 1420 and moves in a substantially circumferential direction, and can be heated by the heating part 2010 to generate steam. To this end, the internal structure allows the flow path to be maximized, and a description thereof will be given later.

The steam generator 2000 includes a body 2100 having a bottom and a side surface and an upper plate 2300 disposed on the upper surface of the body 2100 and having a steam discharge hole 2310, And an intermediate member 2200 disposed between the upper plate portion 2300 and the body portion 2100 to provide a moving path of water bodies and / or steam.

A heater coupling part 2110 is formed on the central side of the steam generating part 2000 so that the heating part 2010 can be fastened to the steam generating part 2000. The heater coupling part 2110 has a hole And a thread is formed on the inner circumference to provide a fastening force. A screw groove may also be formed in a corresponding portion of the heating unit 2010 so as to correspond to the thread of the heater fastening portion 2110. It should be noted that the threads and threaded grooves can be interchanged.

The heating unit 2010 can be disposed in a substantially circumferential direction in the space formed inside the steam generating unit 2000 and the water flowing from the input unit 1420 moves to the outer circumferential side of the heating unit 2010 A discharge passage 2202 may be formed on the inner circumferential side of the passage to be discharged to the upper steam discharge hole 2310 while steam is generated. .

A predetermined partition structure may be formed to extend upward from the side where the heating unit 2010 is arranged so as to partition the steam generating flow passage 2201 and the discharge preparation flow passage 2202, and this will be described below in connection with this.

5 is an exploded perspective view of the steam generating unit of FIG. FIG. 5 (a) is viewed from above, and FIG. 5 (b) is viewed from below.

The body 2100 forms an outer shape of a side surface and a bottom surface of the steam generating part 2000, and the upper part is opened. The side surface is formed with a charging port 2120 connected to the charging portion 1420. The charging portion 1420 may be formed in the form of a nozzle that can be coupled to the outside.

A heater engagement portion 2110 is formed at the center of the body portion 2100 and a path through which a predetermined water body and steam can flow can be provided on the outer peripheral side of the body portion 2100. This path is formed on the upper side of the intermediate member 2200 .

A heating unit 2010 is disposed on the bottom surface of the body 2100 and both ends of the heating unit 2010 are drawn out to allow control power to be input. Accordingly, the heating unit 2010 may be disposed in a manner such that the heating unit 2010 is formed in a U-shape as a whole and surrounds the heater fastening unit 2110.

The intermediate member 2200 inserted into the inner space of the body part 2100 may have a predetermined flow space on the upper side and the heating part groove 2220 may be provided on the lower side to fix the heating part 2010 have. The heating grooves 2220 are concave grooves upwardly corresponding to the arrangement of the heating units 2010 placed on the bottom surface of the body part 2100, and this shape is shown in FIG. 5 (b). The heating grooves 2220 may be formed in a U-shape as a whole. Considering the spatial advantage, it may be considered that a groove corresponding to the lower shape of the heating unit 2010 is formed on the bottom surface of the body part 2100. However, in the intermediate member 2200, It is preferable that the heating grooves 2220 correspond to most of the height of the heating unit 2010, considering that the flow is generated on the upper side and the side and the heat transfer must be performed effectively.

As shown in FIG. 5A, the upper side of the heating groove 2220 has a convex shape, and the partition wall 2210 may extend to the upper side thereof. The upper portion of the partition wall 2210 and the heating groove 2220 define the steam generating passage 2201 and the discharge preparation passage 2202.

At this time, when the heating groove 2220 surrounds the arrangement of the heating unit 2010 as a whole, when the partition wall portion 2210 is entirely connected to the upper side of the partition wall 2210, the steam generating flow passage 2201 and the discharge preparation flow passage 2202 become difficult to communicate with each other. For this purpose, at one end portion of the heating unit 2010 starting from the inside of the body portion 2100, the partition wall portion 2210 above the heating groove 2220 defines a space, and a portion of the partition wall portion 2210 It is preferable to open it. It is preferable that such an open portion is located farther from the inlet 2120 in order to secure the heat transfer path as much as possible.

An opening through which the heater fastening portion 2110 can be inserted may be formed on the center side of the intermediate member 2200.

Shaped top plate portion 2300 is disposed to cover the intermediate member 2200 to form an inner flow path and the upper plate portion 2300 is provided with one or more vapor discharge holes 2310 may be formed.

The steam is supplied to the steam trapping space 1121 at the upper portion of the steam discharge hole 2310 to receive the heat of the heating unit 2010 to be superheated steam.

At this time, a partition wall insertion portion 2320 is formed to extend to the lower side of the upper plate portion 2300. The partition wall insertion portion 2320 is coupled with the partition portion 2210 of the intermediate member 2200, 2201 and the discharge preparation flow passage 2202 are completely separated. In the illustrated embodiment, the partition 2210 is formed in a slit shape and the partition insertion portion 2320 is inserted into a rib.

The partition wall portion 2210 and the partition wall inserting portion 2320 form an open portion at the other end side of the heating portion 2010, i.e., at the side far from the inlet port 2120 to form the steam generating passage 2201 and the discharge preparation passage 2202 .

It is preferable that the steam generating part 2000 and at least the intermediate member 2200 are made of a material having excellent thermal conductivity so that heat transfer of the heating part 2010 can be efficiently performed.

According to this concept, when a water body flows into the outer side of the intermediate member 2200 through the input part 1420, it moves along the circumferential direction to the steam generating passage 2201 defined by the partition wall part 2210, When the heat from the heating groove 2010 is received from the heating groove 2220 and is converted into steam and moved to the discharge preparation flow passage 2202 which is the inner circumference side at the opening portion of the partition portion 2210, And is discharged upward through the steam discharge hole 2310 while being moved in the circumferential direction in the space between the steam discharge holes 2210.

The steam thus discharged is transferred to the circulation passage 1123 formed at the outer circumference of the heating unit 2010 by receiving the heat of the heating unit 2010 while staying in the steam trapping space 1121 formed in the lower part of the partitioning unit 1010, And is moved to the support portion 1020 in a state of being evenly distributed through the distribution space 1122. [

In the case of performing the two-stage heating by separating the generation of steam from the overheating as in the present invention, it is possible to minimize the time required to further increase the temperature while boiling and pressurizing the water with one heater, It should be noted that the apparatus can be made compact.

As a result, it was confirmed that the total sterilization time was 25 minutes when the conventional steam method was followed and the time advantage was maximized because the operation of the equipment was completed within 5 minutes according to the concept of the present invention. In addition, the temperature of the superheated steam generated through the heating unit 2010 took about 3 minutes to reach 200 ° C. The sterilization time of approximately 1 minute is required for the superheated steam of such temperature.

On the other hand, there is a problem that a superheated steam is introduced into the side of the stationary part 3000 so that sterilization is not performed in the past. As described above, there is a need to uniformly distribute steam to sterilize the steam. An example is given below.

6 is a perspective view for explaining an embodiment of a mounting part in the high-efficiency handpiece sterilizer of the present invention.

The mounting portion 3000 may include a predetermined holder portion 3100 to mount one or more handpieces 100 thereon. The holder 3100 may have a bottom surface and may extend upwardly from a disc-shaped base 3010 supported by the support portion 1020.

A plurality of holes may be formed in the base portion 3010 to allow the superheated steam to flow from the distribution space 1122. These holes may be formed in the base portion 3010 such that the superheated steam can flow into the inner periphery of the holder portion 3100 2 hole 3012 and a first hole 3011 which can be introduced into the sterilization space 1110. [

The holder 3100 has a cylindrical shape and a second hole 3012 is formed through the upper and lower portions of the bottom of the holder 3100 to allow superheated steam to flow into the holder 3100. Therefore, when the handpiece 100 is mounted on the holder portion 3100, the superheated steam flows into the inner circumferential side or the bottom side of the mounting portion by the second hole 3012, and the outer circumferential side of the first hole 3011 And sterilization is performed.

Therefore, when the holes for introducing the superheated steam are divided at the inner and outer sides of the holder 3100 as described above, the inner and outer spaces of the inner and outer spaces can be effectively sterilized according to the type of the handpiece 100.

Meanwhile, it is preferable that the grip portion 3200 is formed as a shape extending upward from the base portion 3010. 3, the upper end of the handle 3200 is disposed adjacent to the bottom surface of the opening and closing part 1300 and allows the opening and closing part 1300 to be held and lifted through the gripping or gripping member immediately when the opening and closing part 1300 is opened.

The sterilized handpiece 100 is removed and stored in a state that the mounting part 3000 is fully drawn out and the handpiece 100 requiring sterilization is mounted on the holder part 3100 and put into the sterilization space 1110 Thereby performing the sterilization process described above.

It should be noted that the dismounting structure of the mounting part 3000 not only eliminates the inconvenience of directly inputting the equipment into the conventional chamber, but also provides an advantage of preventing contamination of the sterilizer or the handpiece.

FIG. 7 is a block diagram illustrating a sterilization system to which the high-efficiency handpiece sterilizer of the present invention is applied.

The handpiece sterilizer 1000 includes a casing 1100 and an opening / closing part 1300, and a bracket part 1200 that can be connected to external equipment is formed as described above. The handpiece sterilizer 1000 may be connected to the lower main frame (not shown) and supported in an upright state.

A tank portion 4100 for storing and supplying a water body is disposed at one side of the handpiece sterilizer 1000. The tank portion 4100 is connected to the pump portion 4110 and is supplied by the power of the pump portion 4110 The water body flows into the steam generator 2000 through the line 4111.

The handpiece 100 is supported in the mounting part 3000 disposed inside the casing 1100 and the sterilization is performed by superheated steam as described above. The discharge unit 1410 is connected to the discharge line 4311 to discharge or reduce the sterilized vapor and the valve unit 4300 is further disposed on the path of the discharge line 4311 . The valve portion 4300 functions to control the internal pressure by opening or closing the leakage of the pressure to the discharge portion 1410. For this purpose, the controller unit 4200 controls the valve unit 4300, and the valve unit 4300 is a solenoid valve.

A pressure monitor line 4221 may be additionally connected to the discharge unit 1410 to monitor the pressure inside the casing 1100. A predetermined pressure gauge may be connected to monitor the pressure in real time. The measured result through the pressure monitor line 4221 is calculated by the controller unit 4200 so that control of the valve unit 4300 for maintaining the appropriate temperature and pressure can be performed.

The sensing unit 1510 may include a temperature sensor and may measure the internal temperature to provide a temperature sensing signal to the controller unit 4200. The controller unit 4200 may include a pump unit 4110 and / ) And / or controlling the pressure and temperature by controlling the heating unit 2010 and / or the valve unit 4300. [

The arrangement and the configuration of the above-described configurations are not limited to the illustrated examples.

The sterilizing operation of the handpiece sterilizer and the sterilizing system according to the present invention will be described below. The handpiece 100 is mounted on the holder part 3100 of the mounting part 3000 drawn out to the outside and the opening / closing part 1300 is opened The mounting portion 3000 is seated in the casing 1100. [ Guide means (not shown) such as a projection may be formed between the mounting portion 3000 and the supporting portion 1020 to facilitate position adjustment at the time of insertion.

In this manner, the steam generator 2000 can be operated in the state where the mounting part 3000 is disposed and the opening and closing part 1300 is closed. However, it is preferable that the heating unit 2010 is operated first to perform preheating so that the heating time can be minimized, and then the heating unit 2010 performs preheating and heating for generating steam. For example, after the control power is first applied to the heating unit 2010 to preheat for 2 minutes 30 seconds, the heating unit 2010 can be preheated for 30 seconds. When the preheating is completed, if the water body of the tank part 4100 is put into the charging part 1420 through the pump part 4110, it is heated through the steam generating flow path 2201 on the outer peripheral side of the heating part 2010, 2202 and a steam discharge hole 2310 to be introduced into the steam trapping space 1121. The steam temporarily staying in this space is temporarily heated and moved upward through the circulation channel 1123 through the heating unit 2010 to be sterilized upward along the holes formed in the bottom surface of the mounting part 3000 in the distribution space 1122 And is moved to the space 1110. Thus, the superheated steam generated can be about 200 ° C.

As described above, the base portion 3010 of the mounting portion 3000 is provided with a second hole 3012 for discharging the superheated steam to the inner circumference side of the holder portion 3100 and a second hole 3012 for discharging the superheated steam directly to the sterilization space 1110. [ The holes 3011 are formed, so that the inside and outside of the handpiece 100 can be uniformly sterilized.

In the handpiece sterilizer 1000 of the present invention, the preheating takes about 3 minutes and the sterilization takes about 1 minute, so that the time can be drastically reduced compared to the conventional case.

The temperature and pressure in the casing 1100, more precisely in the sterilizing space 1110, are monitored in real time, and the overall operation control is performed by the controller unit 4200. The temperature of the sensing line 4211 is measured through the valve unit 4300, So that it is possible to control the pressure appropriately as described above.

According to the above-described high-efficiency handpiece sterilizer of the present invention, the time required for generation and heating of steam is overcome and the generation of steam and the formation process of superheated steam are separated from each other so that the time required for sterilization is drastically reduced It provides an advantage that can be done.

In addition, the entire mounting part for mounting the handpiece is detachably formed, not only the ease of use is improved, but also the overall structure is compact, thereby maximizing spatial advantage.
