DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an autoclave .

[0002]

As of the Related Art As is well known, <br/> lid of the sterilization autoclave is strength retention, the need for the gas-tight seal, conventionally is composed of fairly integral structure of a thick alone. Examples of such lids include a clamping rod that extends in the radial direction and has a rotating shaft for opening and closing forward or side of the pressure vessel, and a lid that slides vertically to open and close. There is something that I did. However, in each case, the moving space for opening and closing the lid is large, and the position occupied by the lid when opened is limited, which imposes various restrictions when installing the pressure vessel.

[0003]

SUMMARY OF THE INVENTION The present invention provides a seal
Together it is good, moving space of the lid assembly small Io
It is intended to provide autoclaves .

[0004]

That is, the present invention provides:
A plurality of beam members 1 are juxtaposed to constitute a lid assembly 4, and the lid assembly 4 is located on the front surface of the pressure vessel 5, at a closed position A for closing the opening 6, and outside the side wall of the pressure vessel. A guide member 12 is provided so as to be movable while being bent between an open position B which is positioned and opens the opening 6.
The material 12 has a bent portion located outside the closed position A.
The packing 9 extends into the opening position B through the opening 122 and is inserted into the groove 8 recessed in the periphery of the opening 6, and the packing 9 is inserted into the opening portion of the lid assembly 4 at the closing position A. An auto that is configured to press against the 6th peripheral edge
It features a clave .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A beam member is juxtaposed to constitute a bendable lid assembly. For example, adjacent beam members are connected by a hinge, and a sealing elastic body is interposed in a gap at each connection point. The lid assembly is installed so as to be movable while bending between a closed position for closing the front opening of the pressure vessel and an open position for opening the opening (any position on the side wall of the pressure vessel). I do.

When the lid assembly is opened and closed, a guide member extending between the closed position and the open position of the lid assembly with a bent portion interposed therebetween is provided in the vicinity of the pressure vessel opening. The cover assembly is moved while changing its direction with the curved portion of the guide member interposed therebetween. At this time, the hinge and the elastic body for sealing flexibly correspond to each other, so that the cover assembly can move in a relatively small moving space. Moving.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings.

The autoclave main body as the pressure vessel 5 has a sterilization chamber 7 therein and an opening 6 for taking an object to be sterilized into and out of the sterilization chamber 7. The lid assembly 4 of the present invention connects the adjacent beam member 1 (in the embodiment, the channel steel) and the beam member 1 with the hinge 2 so as to cover the opening 6.
The elastic body 3 for sealing is interposed in the space below the hinge 2 by a suitable means.

The lower surface of the sealing elastic body 3 of the lid assembly 4 is finished to be flush with the bottom surface of the beam member 1, and preferably faces the triangular projections 3 ', 3' at both ends. The sealing property of the opening 6 is enhanced by closely contacting the notch corner 1 ′ of the beam member 1.

A packing 9 is fitted in a groove 8 recessed around the opening 6 as shown in FIG. 1, and a pressure for pressing the packing 9 from the back is inserted into the groove 8. One end of a pipe 10 for feeding gas is facing (see FIG. 2).

The beam members 1 are connected only at the portions connected by the hinges 2, and the adjacent beam members are free without being fixed. For this reason, even when the lid assembly 4 is bent, the circumferential gap between the adjacent beam members 1 and 1 is widened, as shown in FIGS.
Can be slid and stored in parallel with the side wall 11 of the pressure vessel 5 (in the illustrated embodiment, in parallel with the upper side wall 11).

A guide member 12 serving as a guide for slidingly storing the lid assembly 4 is provided between a closed position A and an open position B with a bent portion 122 interposed therebetween. In this embodiment, since the extension member 123 of the guide member 12 is installed in parallel with the upper side wall 11 which is the opening position B, the lid assembly 4 is separated from the opening 6 and then the lid assembly 4 shown in FIG. As described above, it retreats to a predetermined position on the side wall 11.

The cover assembly 4 of the guide member 12
The peripheral portion 121 facing the closed position A of the
In order to receive the internal pressure of the packing 9 and the pressing force of the packing 9, it is preferable to reinforce the packing 9 to a predetermined strength (see FIG. 2).

Opening and closing of the lid assembly 4 may be performed manually, but appropriate driving means for reciprocatingly sliding in one direction,
For example, if a gear motor or the like is used, the opening and closing operation of the entire lid assembly can be easily automated with a simple driving mechanism.

According to the above-described configuration, the opening 6 is formed by the lid assembly 4.
When the lid is closed, the lid assembly 4 is slid from the open position B above the pressure vessel 5, and the front surface is moved to the closed position A facing the opening 6 and stopped. next,
The pressure gas is supplied from the back of the packing 9 to cover the lid assembly 4.
The packing 9 is pressed against the front of the container to seal it. When the lid assembly 4 is opened from the opening 6, the opening 6 can be opened by releasing the pressing operation of the packing 9 and sliding the lid assembly 4 upward.

As the sealing elastic body 3 in the present invention, a nylon resin having high mechanical strength and a synthetic resin material having a certain elasticity at room temperature are desirable. Materials can also be used.

Further, in the above embodiment, the lid assembly is constituted by the beam members connected by a single hinge, but the hinge mechanism is provided between both members by modifying the opposing side portions of the beam members. Is also good.

[0018]

According to the present invention, the lid assembly can be moved in a relatively small moving space, and the restriction on the installation of the pressure vessel can be greatly eased as compared with the conventional one. it can. In addition, the lid assembly passes through the bend from the closed position
Lid assembly after reaching the closed position of the front opening of the pressure vessel
Sealing is good because the packing is pressed against the body and sealed.
You can keep it good.
