Hereinafter, main components of the autoclave according to an embodiment of the present invention will be described based on the drawings.

1 and 2, a high-pressure sterilizer according to an embodiment of the present invention, the chamber 100 is provided with an entrance, the door 100 for opening and closing the entrance of the chamber 100, the chamber 101, the chamber The air injection line 110 and the chamber 100 installed in the bottom surface of the 100 and injecting air into the heater 105 for generating steam and the chamber 100 and having a first sole valve 111 for opening and closing the line ) Exhaust line to exhaust the air and the second brush valve 122 for opening and closing the line is installed, the ejector 130 is connected to the exhaust line 120 to provide a vacuum pressure to the chamber 100, and a heater It includes a control unit 140 for controlling the operation of the (105), the first brush valve 111, the second brush valve 122, and the ejector 130.

The ejector 130 is formed with an inlet 131a and an outlet 131b provided with a venturi conduit 131 'along a central line, and an exhaust line 120 is connected but crossing the venturi conduit 131' The water pressure line 134 connected to the inlet of the venturi pipe 131, the venturi pipe 131 ', on which the furnace 132 is formed, passes water through the venturi pipe 131', and the water pressure line 134 is installed. And a third sole valve 133 that opens and closes the line 134.

The autoclave according to this embodiment is sterilized by loading a sterilization object inside the chamber 100 through the door 101. Sterilization of the autoclave according to this embodiment follows the following procedure.

According to this embodiment, the first brush valve 111 is opened and air is injected into the chamber 100 to increase the pressure of the chamber 100 (a), and the heater 105 is operated to move the interior of the chamber 100 Steam is generated (b), and when the inside of the chamber 100 reaches a set temperature, the set temperature is maintained for a certain period of time (c), the second sole valve 122 is opened, and a drainage of the chamber 100 is made ( d), as the third sole valve 133 is opened, water passes through the Venturi conduit 131 ', whereby the process of exhausting and drying the interior of the chamber 100 (e) is performed.

The control unit 140 includes a memory for storing a program that automatically performs steps (a), (b), (c), (d), and (e) and a processor for processing the program. The control unit 140 may include an integrated touch panel 145 on which a user interface is mounted.

Chamber 100 is made of a high pressure of the internal steam according to the air injection and steam generation for a certain time, the interior of the chamber 100 is created a sterilized environment of high-pressure steam that can sufficiently penetrate the steam to the sterilized object loaded. After the set temperature is maintained in the chamber 100 and sterilization proceeds for a certain period of time, drainage of water accumulated in the chamber 100 is performed, and the sterilized object is dried while the steam is exhausted. Exhaust and drying is performed through the ejector 130.

The ejector 130 applies vacuum pressure to the interior of the chamber 100 while water having a higher density than water vapor inside the chamber 100 passes, while vacuum pressure is applied to the exhaust pipe while water passes through the venturi pipe 131 '. Occurs. The vacuum pressure of the exhaust line 120 is transmitted to the chamber 100, and the water vapor of the chamber 100 flows out through the outlet of the ejector 130.

The autoclave according to the present embodiment as described above, as a vacuum generating fluid of the ejector 130, by using water having a higher density than water vapor to dry the sterilized object with a sufficient vacuum pressure to exhaust the interior of the chamber 100 . The number of direct water pipes provided to the ejector 130 may be used.

Referring to FIG. 3, the ejector 130 further includes an injection nozzle 135 installed at the inlet of the Venturi conduit 131 'and connected to the hydraulic line 134. The injection nozzle 135 may have a tapered shape with a narrower diameter as it goes toward the flow direction of water.

The ejector 130 is configured so that water is injected from the injection nozzle 135 to pass through the Venturi conduit 131 ', and is sufficient for the suction conduit 132 by water passing through the Venturi conduit 131' at a high pressure and high speed. Vacuum pressure is generated. The vacuum pressure can be adjusted according to the water pressure.

The exhaust line 120 is connected adjacent to the inlet side of the Venturi pipe 131 'from the Venturi pipe 131, and may be disposed to cross the tapered rear end side of the injection nozzle 135.

In this embodiment, since the suction line 132 to which the exhaust line 120 is connected is disposed on the rear end side of the injection nozzle 135, vacuum pressure is applied to the suction line 132 by water injected from the injection nozzle 135. This happens. Since water is injected at a high pressure from the injection nozzle 135, water flows rapidly from the inlet side of the venturi pipe 131 'to the outlet side, and passes through the venturi formed by a narrow flow path of the venturi pipe 131'.

The ejector 130 may further include a water pump 136 that pressurizes the hydraulic pressure line 134. The water pump 136 may be located between the venturi conduit 131 ′ and the third sole valve 133 in the hydraulic line 134.

The water pump 136 causes water passing through the hydraulic line 134 to be pressurized and accelerated to flow into the Venturi pipeline 131 '. As described above, the water is further pressurized and accelerated by the operation of the water pump to flow into the venturi conduit 131 ', and thus a larger vacuum pressure may be formed in the intake conduit 132 through the venturi conduit 131'.

The autoclave according to this embodiment is connected to the chamber 100 and supplies water inside the chamber 100 and further includes a water supply line 150 installed with a fourth brush valve 154 for opening and closing the line. The water supply line 150 uses direct water from the water supply line, but a filter may be installed.

As described above, the embodiments of the present invention have been described, but on the basis of this, those skilled in the art can add or change the components within the scope not departing from the essential technical spirit of the present invention described in the claims. The present invention may be variously modified and changed by deletion, addition, or the like, and this is also included within the scope of the present invention.
