Next, the detailed description of the operation of the present invention made as described above is as follows.

Through the high-pressure steam sterilizer equipped with a washing function according to an embodiment of the present invention, a single washing function, a washing and sterilization function, a single sterilization function, etc. can be selectively performed according to the operation of the operation panel 14 by the user. .

The single cleaning function is a simple cleaning function, and after a predetermined object to be sterilized is put into the chamber 20, cleaning with hot water is performed by the control of the control unit 100 according to the operation of the operation panel 14. After the drying process is performed, a drying process is performed through the drying fan 82 .

In the washing and sterilization function, as in the single washing function, the drying operation does not proceed immediately after the washing function is performed, but the drying fan (82 ) through the drying process.

In the single sterilization function, the washing function does not proceed, and the sterilization function through the steam supply unit 80 proceeds, and then the drying process proceeds through the drying fan 82 .

Here, since the sterilization function through the steam supply unit 80 and the drying process through the drying fan 82 are well-known techniques in the relevant field, a detailed description thereof will be omitted.

Meanwhile, referring to the washing function, a series of processes including a water supply process, a soaking process, a washing process, a rinsing process, and a drying process are sequentially performed.

In the water supply process, a certain amount of water is supplied into the chamber 20 through the check valve 30 connected to the water supply pipe while the water supply solenoid valve 31 is opened under the control of the control unit 100, It is stored, and at this time, the drain solenoid valve 71 maintains a closed state.

That is, when the water supply solenoid valve 31 is opened, as water is supplied from the outside through the water supply pipe, the opening and closing member 32 in the base member 40 provided in the check valve 30 is connected to the base member 40. While being pushed to the side, the inside of the connecting member 50 is opened, and the inside passing through the connecting member 50, the water supply hole 34 of the opening and closing member 32 and the spray hole 44 of the base member 40 ) is formed (see FIG. 8a).

In the soaking process, after a certain amount of water is filled in the chamber 20 through the water supply process, the heater 60 inside the chamber 20 is operated under the control of the control unit 100, and the chamber 20 The process of heating the water filled in to the set temperature (approximately 100 ℃) will proceed.

Accordingly, in the chamber 20, it is possible to easily clean various foreign substances adhered to the object to be sterilized through steam generated by heating the stored water.

As shown in FIG. 7 , in the washing process, after the water stored in the chamber 20 is drained, high-pressure water is passed through a plurality of check valves 30 according to the control of the control unit 100 by a set program. While spraying, the cleaning process is repeated about 3 to 5 times, and through this, various foreign substances attached to the object to be sterilized can be completely removed.

In the washing process, when water is sprayed through the plurality of check valves 30, the water may be sprayed through all nozzles at the same time, or may be sprayed through only some nozzles, or the nozzles installed on the left and right sides of the chamber may operate alternately. It may be controlled so that water is sprayed sequentially while being.

Thereafter, in the rinsing process, additional water is sprayed through a plurality of check valves 30 to perform a rinsing operation for the object to be sterilized, and in the drying process, a drying fan is controlled by the control unit 100. As the 82 is operated, warm air for drying the object to be sterilized put into the chamber 20 is supplied over a certain period of time.

Meanwhile, in the sterilization function or the washing and sterilization function, when the sterilization operation is in progress, the check valve 30 moves inside the chamber 20 by the operation of the steam supply unit 80 under the control of the control unit 100. As the high-temperature and high-pressure steam is filled, the opening/closing member 32 inside the base member 40 moves toward the connection member 50 by steam pressure.

Accordingly, the O-ring 38 installed on the central axis 36 of the opening/closing member 32 of the check valve 30 moves toward the O-ring contact groove 56 of the opening/closing member 50 and adheres to the corresponding check valve 30. It becomes possible to close (see Fig. 8b).

Therefore, while the interior of the chamber 20 is maintained in a tightly sealed state through the operation of the plurality of check valves 30, high-temperature and high-pressure sterilization of the object to be sterilized can be performed over a certain period of time.

On the other hand, although the preferred embodiments of the present invention have been shown and described above, the present invention is not limited to the specific embodiments described above, and the technology to which the present invention pertains within the scope of not departing from the gist of the present invention claimed in the claims. Various variations and modifications are possible by those skilled in the art, and these variations and modifications should not be individually understood from the technical spirit or perspective of the present invention.
