Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic door lock device for a medical high pressure steam sterilizer,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic door lock apparatus for a medical high pressure steam sterilizer, and more particularly to an automatic door lock apparatus for a medical high pressure steam sterilizer, Pressure steam sterilizer for automatically sterilizing and drying an object to be sterilized such as a liquid, a packaged product, and an unpackaged product by selecting an operation cycle according to the kind thereof.

Generally, various medical instruments are required to be sterilized and stored. To this end, a method of using a medicine or sterilizing by using a high-temperature steam is disclosed. In the case of a medical instrument which is not directly used in the human body, it can be sterilized by using a medicine, but most of the medical instruments used in the human body are sterilized by using high temperature and high pressure steam.

A conventional medical high pressure steam sterilizer is a device for sterilizing and disinfecting various medical equipment, surgical clothing, gowns, etc. for sterilization and disinfection by a high-pressure steam for the treatment performed in a hospital or the like, And sterilization treatment is carried out using them.

BACKGROUND ART A conventional medical high-pressure steam sterilizer has a chamber in which a sterilization chamber for containing various medical devices, clothes such as surgical gowns and gowns (hereinafter referred to as objects to be sterilized) is formed, and a door A vacuum pump for lowering the atmospheric pressure and the humid air in the chamber; a solenoid valve for shutting off and supplying the distilled water and the steam to the chamber; And the like.

In the conventional medical high-pressure steam sterilizer having the above-described configuration, the object to be sterilized is placed in the sterilization chamber of the chamber, and then the distilled water stored in the water storage tank is supplied to the sterilization chamber, and the heater is operated to generate high- Thereby sterilizing the sterilized object.

However, since the conventional medical high-pressure steam sterilizer is configured to manually open and close the door, the degree of locking is different for each user. This allows the door to be closed more strongly than the closing standard required by the chamber depending on the user's force when closing the chamber, or vice versa. That is, when the chamber is closed more strongly than the chamber closing standard, there is a great deal of force when the door is opened after the high-pressure sterilization process is completed. On the contrary, when the user's strength is low or the door is closed by the user's careless operation If the chamber is closed with a force below the reference, the door may not overcome the high pressure formed in the chamber during the high pressure sterilization process, resulting in an accident that the chamber may explode.

Therefore, the high-pressure steam sterilizer should be constructed so that the door can always be closed and locked with a constant force to conform to the chamber closure criteria regardless of the user's skill.

On the other hand, the chamber discharges the vapor inside the chamber after the high-pressure sterilization treatment, and the chamber is held in a strongly adsorbed state because the inside of the chamber is lowered to a high vacuum state. Accordingly, when the opening of the chamber is closed immediately after discharging the steam, it is very difficult to open the chamber because the force is very great for rotating the locking device to open the door. Thus, the chamber was opened by opening the door after waiting for a long time until the temperature inside the chamber was lowered to the room temperature. As a result, the utilization time of the autoclave is reduced, and the efficiency of use is greatly reduced.

In addition, the conventional medical high-pressure steam sterilizer can not withstand the pressure generated inside the chamber, so that the locking part of the locking device is easily broken, and hot water vapor and pressure generated during sterilization frequently leaks to the outside while pushing the door. As a result, not only the performance of the sterilizer is deteriorated but also a safety accident that burns the leaked steam occurs.

In addition, in the conventional medical high-pressure steam sterilizer, since the locking device of the door is manually opened and closed, there is a risk of a safety accident that the door is opened during operation of the device.

A control panel mounting base 120 is formed integrally with the upper cover 101 and a control panel 200 is installed on the front surface of the control panel mounting base 120.

A door (DOOR) 110 is installed on the front surface of the medical high-pressure steam sterilizer 100. When the door 110 is opened, a chamber 300 having a hexagonal structure is installed. Herein, the chamber 300 is filled with objects to be sterilized such as various medical instruments, rubbers, clothes (surgical gowns, gowns, etc.), fabrics, liquids, Sterilized and dried.

A locking device 500 for opening and closing the door by the rotation of the motor 510 may be installed in the door 110. The locking device 500 may be configured to open and close the door 110 by engaging with a locking member 180 disposed at a front side of the chamber 300.

The locking device 500 is configured to be locked and unlocked by the locking member 180 by rotating the lock gear 540 by normal and reverse rotation of the motor 510 to thereby open and close the door 110 .

For example, as shown in FIGS. 2 and 15 to 24, the locking device 500 may include a locking member (not shown) disposed at one side of a horizontal frame 501, which is horizontally disposed at the center of the interior of the door 110 180, respectively. At this time, the locking device 500 includes a motor 510, a motor gear 530, a lock gear 540, a manual gear 550, a first micro switch 560, a photosensor 570, .

The motor 510 may be a planetary reduction gear motor. At this time, the planetary reduction geared motor is a device that transmits power by rotating one gear of a pair of gears engaged by the motor.

The motor gear 530 rotates the lock gear 540 and the passive gear 550, which are engaged with each other in one direction and the other direction, by a predetermined angle by the rotation of the motor 510 do. A coupling 520 may be additionally provided between the motor 510 and the motor gear 530.

The lock gear 540 is rotated at a predetermined angle by the motor gear 530 so that the locking groove 541 is coupled to and separated from the locking pin 183 of the locking member 180, Lt; / RTI >

For example, the lock gear 540 has a gear tooth 542 meshing with the motor gear 530 at a predetermined length on a side surface thereof, and the locking member 180 are formed with locking grooves 541 which are engaged with and separated from the locking pins 183 of the first and second locking members 180, 180. Further, a fixing hole 544 into which the stopper pin 430 is inserted is formed on the side surface. Accordingly, the lock gear 540 is rotated at a predetermined angle around the rotating shaft 543 by the motor gear 530.

The first micro switch 560 senses the movement of the pin 561 according to the rotation of the lock gear 540 and discriminates the opening and closing of the door 110.

For example, the first micro switch 560 is turned on when the locking groove 541 of the lock gear 540 is locked with the locking pin 183 of the locking member 180, And is turned off when the locking grooves 541 of the lock gear 540 are completely released from the locking pin 183 of the locking member 180 to be opened. The sensing signal of the first micro switch 560 is used as a control signal for opening and closing the door 110 by controlling the operation of the motor 510.

The photosensor 570 is installed at one side of the lock gear 540 and controls the rotation range of the lock gear 540 by detecting the rotation position of the lock gear 540.

For example, the photosensor 570 is turned off when the locking groove 541 of the lock gear 540 is locked to the locking pin 183 of the locking member 180 to be locked (ON) when the locking groove (541) of the lock gear (540) completely disengages from the locking pin (183) of the locking member (180). At this time, the sensing signal of the ON and OFF states of the photosensor 570 controls the operation of the motor 510 in the same manner as the first micro switch 560, As shown in Fig.

For example, when the stopper pin 430 of the safety lock device 400 is released from the fixing hole 544 of the lock gear 540, the detection signal of the first micro switch 560 is turned on And the control unit of the control panel 200 rotates the motor 510 to open the door 110 when the sensing signal of the photosensor 570 is OFF. At this time, the motor 510 rotates the motor gear 530 counterclockwise to control the rotation of the lock gear 540 to the control unit of the photosensor 570.

On the contrary, when the stop signal of the first micro switch 560 is turned off while the stopper pin 430 of the safety lock device 400 is released from the fixing hole 544 of the lock gear 540, And when the sensing signal of the photosensor 570 is ON, the control unit of the control panel 200 rotates the motor 510 to rotate the door 110 in a forward direction. At this time, the motor 510 rotates the motor gear 530 in a clockwise direction so that the lock gear 540 is rotated to the control unit of the photosensor 570.
