Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a multi-layer transparent plate in which an insulating gas having a specific gravity higher than that of air is sealed in a space, and its purpose is to manufacture a multilayer transparent plate filled with a large amount of granular desiccant. Two passages are formed in the frame member 1, which is made up of a screw and a plurality of 'lIi fittings, to prevent the desiccant from leaking from both passages. There are two things you can do to fill it up.

For the windows and doors of general houses, refrigerators, low-humidity carbon dioxide cases, and other refrigeration equipment, multi-layer transparent gases with a specific gravity greater than that of air (such as insulating gas that does not easily cause convection, such as Mr or SFa, etc.) are sealed in the space. It is known that by using @, you can reduce the indoor heating and cooling load and the refrigeration load in the refrigerator, and also reduce the amount of dew condensation on the outer surface of the 41-layer transparent plate.

However, these multi-layer transparent plates may consist of two or more transparent plates and a frame member, or they may consist of multiple transparent plates and a frame member filled with a large amount of granular desiccant. There are two species. The former multi-layer transparent plate evacuates the space and then fills the space with insulating gas, but from the viewpoint of the moisture contained in the insulating gas and the moisture permeability of the V-layered material, # ! If used for a long period of time outside of one circle with a large jet difference or outside one circle, condensation will occur on the opposing surfaces of both transparent lenses.
There is also 4. On the other hand, the latter multi-layer transparent board has a space C due to the moisture and moisture permeability of the insulating gas in the frame member;
h The hot gas supply passage and the air exhaust passage are separated by a spacer 1.
:During the manufacturing process, the desiccant may leak into the space and outside from both passages, such as removing the desiccant in the space after filling with insulating gas, refilling the frame member with desiccant, etc. , post-processing operation a had to be performed.

The present invention improves on the points mentioned above.

To explain the uninvented practical example according to aspect (2) below, the first
1! I and (1) shown in Fig. 2 are multi-layer transparent plates used for refrigeration, freezing, or cold storage machines, and general honeycomb windows. C: Interposed between two transparent plates C2 (2B) made of glass and the peripheral end surfaces of opposing surfaces of both transparent plates.

As shown in FIG. 7, a half-helmet product t'x is installed so that the spacer (4A) is at the top, and fixed with a suitable fixing. After that, as shown in Figures 7 to s9, gas supply IIA (not shown) C2 is connected to a supply nozzle 041 consisting of a long and narrow lightning.
Insert it into the space (5) circle through one passage consisting of the opening (11B) and the through hole (1! IB), and position its tip into the space (5) circle Fs.

With the supply of this insulating gas, the air in the space (5) is pushed upward and exhausted from the exhaust nozzle Q9 to the outside as shown by the arrow. (not shown) C: more insulating gas IG+

I (12m) (12/)V Because it is used as a leak prevention member for the desiccant (8), 111m transparent #1 (llv') can be assembled without using a new leak prevention member, and it is a semi-finished product. When moving the multilayer transparent plate (11 and filling with insulating gas O), the desiccant (8) enters into or outside the space (5) from the opening (11B) and through holes (13A) (15B and). ) can be reliably prevented from leaking. Therefore, the post-processing process caused by the leakage of the desiccant (8) as in the conventional method is also difficult. 5) The process of removing the desiccant (8) from the circle and replenishing the desiccant (8) into the hollow part (9) can be completely eliminated.

After arranging the semi-finished product so that the spacer (4A) is located at the upper part C:, an insulating gas l0IV with a higher specific gravity than air is injected into the space (51) from the supply nozzle O- inserted into one passage.
In order to supply the gas, the space (5

'There is no need to carry out, and there is no need to carry out the air discharge passage.

The air in the hollow section can be automatically discharged and replaced with almost no residual air in the space.

9 The durability of the desiccant can be improved as above, and since both passages are closed by the sealing member, the hollow part can be glued at the same time as Ir hot gas is filled in, which shortens the manufacturing process and the patent application. I can figure it out.
