FIG. 7 is a diagram illustrating an example of a processing method for glass plate 12 of refrigerator-freezer 1 according to Embodiment 4 of the present invention. The glass plate 12 is tempered to ensure safety against impacts. There are many processing methods for the strengthening process, and here, the heat strengthening process will be described, but the strengthening process is not limited to the process.

A glass plate 12 that is a part to be strengthened is installed on the conveyor 15 and is conveyed into the strengthening furnace 16.
The glass plate 12 heated at a high temperature in the tempering furnace 16 is subjected to a forced air cooling process using a forced air cooling device 17 installed at the outlet in the tempering furnace 16 after the heating, and the temperature of the glass plate 12 is lowered and heated. Complete the strengthening process.
Although the temperature in the tempering furnace 16 is largely dependent on the equipment state, the glass plate 12 is heated to an average of over 700 ° C. In forced air cooling after heating, the temperature of the glass plate 12 is adjusted to be about 40 ° C.
By performing the heat strengthening treatment in this way, a compressive stress layer is generated at a thickness of about 1/6 of the surface of the glass plate 12, and the wind pressure resistance is about 3.5 to 5 times that of ordinary float glass. Ensure strength.

  FIG. 8 is a diagram illustrating another example of the processing method of glass plate 12 of refrigerator-freezer 1 according to Embodiment 4 of the present invention, and includes a bending process in the processing process. FIG. 8 shows that the provision of the bending step 18 of the glass plate 12 in the heat strengthening step eliminates the need for a separate bending step and can be handled with minimum equipment. ing. When bending is required, the bending receiving jig 19 is set in advance on the conveyor 15, the glass plate 12 is placed on the bending receiving jig 19, and the tempering furnace 16 is charged.

FIG. 9 is an enlarged view showing a step of bending the glass plate 12 of FIG. The glass plate 12 placed on the bending work receiving jig 19 is automatically inserted into the bending work process 18 after exiting the tempering furnace 16 when the heating for heat strengthening is completed. The glass plate 12 is pressed by the bending pressing jig 20 in a state where the temperature of the glass plate 12 is high, and is processed into a bent cross-sectional shape from a flat plate. When the bending amount is large, the press is performed in several times so that the glass is not broken in the middle.
After the bending process, the glass sheet 12 enters the tempering furnace (separate body) 16a shown in FIG. 8 and cools the glass plate 12 to around 40 ° C. using the forced air cooling device 17 installed in the tempering furnace (separate body) 16a. To do.
By processing in this way, it is possible to ensure a wind pressure strength of about 3.5 to 5 times that of ordinary float glass while giving the glass plate 12 a bent shape.

  Further, when the thickness of the glass plate 12 is less than 2 mm, the heat strengthening process cannot be performed, and thus chemical strengthening may be performed after the bending process. In this case, it is possible to obtain a wind pressure strength of about 5 times that of ordinary float glass, and it is possible to ensure a strength equal to or higher than that when a heat strengthening step is performed. In the case of chemical strengthening treatment, drilling and cutting can be performed after the treatment, so that the degree of freedom of the external design is greatly improved.

As for the glass plate 12, organic printing and inorganic printing are given to the glass plate back surface (foaming heat insulating material contact surface). Organic printing is printing using a resinous ink that cures at room temperature that allows color preparation, and is a printing process that prints ink on a glass surface using a silk screen technique. Inorganic printing is printing using an ink mainly composed of glass powder and inorganic pigment, and is a printing process in which the ink is baked at a high temperature after printing and the ink is fused to the glass. Organic printing is a printing process after bending, and inorganic printing is a printing process before bending.

  When the printing process applied to the curved surface portion 12a is to be performed after bending, when the general screen printing is to be performed, the squeegee contact level to the curved surface portion 12a is not stable, and the printed film thickness is large. There is a risk of printing defects such as variations and “smear”.

In the printing of the curved surface portion 12a, it is possible to complete the printing with a stable film thickness by performing inorganic printing before the bending process, and simultaneously perform the paint baking process in the bending process in which the heat treatment is performed, It becomes possible to increase the production yield.
Moreover, you may implement the whole printing by inorganic printing. When the entire printing is performed by inorganic printing, the entire printing process can be completed before bending, and the time can be shortened and the production yield can be improved by omitting the organic printing process.

  After the bending process, it is possible to perform a printing process by screen printing on an unprinted portion that is relatively flat. By applying organic printing, the range of design is further expanded.

  You may print on the surface side (design surface side) of the glass plate 12. FIG. In particular, when installing a manufacturer's logo, touch panel, etc., it is used for printing in a relatively small range, such as showing the initial touch position.
