The conventional sterilizer has a function of disinfecting the apparatuses by steam heat, and there is a problem that a separate dryer is installed in order to disinfect the surgical gown or surgical gloves, and the use thereof is troublesome.

In addition, since the heater is structured to be heated by contact with water in a state in which the heater is installed in the chamber, there is a risk of electric shock as well as a failure of the heater due to direct water contact, and water droplets are often formed in the chamber. .

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a method of automatically disinfecting and drying a surgical gun, And a sterilizer for medical use.

In order to achieve the above object, the present invention provides an air supply system comprising: an air supply line connected to a chamber through an air supply member, a filter and a solenoid valve, a water supply line connected to a chamber through a water tank and a solenoid valve, A steam discharge line connected to the chamber through a safety valve and an exhaust valve from the water tank, and an exhaust line connected to the water tank through a solenoid valve in the steam discharge line. A pressure sensor, a temperature sensor and a pressure gauge for connecting the steam discharge line to the pressure sensor, and a water level sensor for controlling the inflow of water into the chamber and the water tank.

Another feature is that the chamber is formed as a double wall having an inner wall and an outer wall, and a heater is provided on the outer surface.

The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an appearance of the present invention. FIG. 1 is a perspective view of a rectangular housing 1 in which a control device 2 having a display portion 5 is provided on one side of a front face of the rectangular housing 1, And a water inlet 6 is formed on one side of the upper surface so as to supply water to the water tank while discharging steam and pressure.

Reference numeral 26 denotes a recording apparatus for a recording sheet (recording apparatus) which allows the recording of the pressure and temperature conversion to be known.

2 is a system structure showing the construction of the present invention. The system is constructed inside the enclosure 1 and includes a chamber 7 for disinfection and loading of a dry product when the door 3 is opened, And a water tank 8 for discharging water and steam to the water tank 8. The water tank 8 is connected to the water inlet 6 exposed to the outside.

Between the chamber 7 and the water tank 8, an air supply member 9 for forcibly sending air by a compressor or a vacuum pump or the like, and a filter 10 for removing germs and contaminants from the air blown, And an air supply line (A) for supplying air to the chamber (7) via a solenoid valve (11) for controlling the entry and exit of air.

A water supply line B in which the water in the water tank 8 is supplied to the chamber 7 via the solenoid valve 12 is provided and the pressure in the chamber 7 is decreased while being connected to the water supply line B And a pressure drain line (C) communicating with the water tank (8) through a solenoid valve (13) so as to adjust the amount of the water.

The steam discharge line D is constituted so that the steam generated in the chamber 7 flows into the water tank 8 through the exhaust valve 14 and the safety valve 15, And an exhaust line (E) connected to discharge the residual air in the chamber (7) and through a solenoid valve (16) for preventing reverse flow.

A temperature sensor 17 and a pressure sensor 18 are connected to the steam discharge line D so as to control the set temperature and pressure and further a pressure A gauge 19 is provided.

Each of the water level sensors 20 and 21 is provided for controlling the amount of water to be introduced into the chamber 7 and the water tank 8 and these sensors are controlled by the control device 5. [

The solenoid valves 9 (11), 12 (13) and 16 at all times are automatically operated in accordance with the control signal set by the control unit 5.

Reference numeral 22 denotes a temperature switch, and reference numeral 23 denotes a manual valve for discharging water to the water tank.

3 is a transverse sectional view of the chamber. The chamber 7 has a body shape of a double wall having inner and outer walls 71 and 72 to prevent water droplets from being formed on the inner wall 71 due to water vapor, And a placement plate 73 having a flat bottom formed integrally with the inner wall, and a water tank 74 is formed at a lower portion thereof.

A heater (24) is provided around the lower surface of the outer surface of the chamber (7) to heat the water introduced into the water tank (74).

The operation and effect of the present invention thus constructed will be described in detail as follows.

The operation of the main switch 25 of the control box 2 first causes the chamber 7 to be heated by the operation of the heater 24 and simultaneously the operation of the air supply member 9 Air and steam remaining in the chamber 7 due to the inflow of fresh air into the chamber 7 through the air supply line A is supplied to the water tank 8 through the vapor discharge line D and the exhaust line E And is discharged to the outside through the water inlet 6 formed in the water tank 8 to exchange the air.

In this state, the user selects drying, disinfection, or the like to be performed on the display unit 5 of the control device 2 according to the purpose and use of the user. Disinfection may be performed, for example, by selecting an article such as a surgical scissors, Start.

The water in the water tank 8 is supplied to the chamber 7 through the water supply line B and the water is supplied to the chamber 7 through the water supply line B. When the disinfection function is selected, And water is supplied to the sinker 7 by the operation of the water level sensor 21. When water is supplied to the sinker 7, the water is heated by the heater 24, And the solenoid valve 16 is opened to discharge the cold air in the chamber 7 through the exhaust line E while the chamber 7 is closed ) At the set temperature.

When the primary set temperature rises, when the solenoid valve 16 is opened by the control unit 2 and reaches the disinfection set temperature (about 130 ° C.), all the solenoid valves are blocked by the signal, The disinfection of the articles stored in the chamber 7 is automatically performed and the power of the heater 24 is automatically turned off so that the chamber 7 is disinfected with the high temperature steam for the selected disinfection temperature and time.

The abnormal vapor pressure in the chamber 7 flows out to the water tank 8 through the pressure drain line C. When the pressure exceeds 0.4 kg / m 2 in the chamber 7, the solenoid valve 12 So that the valve closed by the foreign substance introduced into the water tank 8 at the time of water supply acts inversely to the high pressure to remove the foreign substances that are blocking, Thereby smoothly performing the water supply to the water tank 7.

On the other hand, in the case of operating the operation clothes, when the drain button is selected, only the solenoid valves 11 and 16 of the air supply line A are turned on and the solenoid valves 12 and 13 are turned off, In this state, the forced air blowing air of the air supply member 9 flows into the water tank 8 through the exhaust line E through the chamber 7 and then is exhausted to the outside through the water inlet 6, 7) to dry the surgical clothing and the like.

In addition, since the chamber 7 is formed of a double wall and indirectly heats water, disinfection due to the formation of water droplets and inhibition of the dry function can be prevented, and electric shock due to the heater can be prevented.

The temperature and pressure in the chamber 7 are displayed by the display of the display unit 5 by the sensing of the control sensor and the pressure is marked by a separate pressure gauge 19, .

As described above, according to the present invention, the respective functions are organically operated by the control device so that the automatic function can be performed in parallel with the automatic disinfection, thereby providing ease of use, and the effect of improving disinfection, dry function and safety have.
