Hollow glass door and manufacturing method thereof

Abstract

The invention provides a hollow glass door and a manufacturing method thereof. The hollow glass door comprises a door frame, an outer glass panel and an inner glass panel. The outer glass panel and the inner glass panel are mounted on the door frame. The hollow glass door further comprises a spacing assembly which comprises a spacer and a waterproof gas-permeable membrane. The spacer is clamped between the outer glass panel and the inner glass panel in a sealing mode. A plurality of air holes are formed in the spacer, and the waterproof gas-permeable membrane is attached to the spacer and covers the air holes. The air holes are covered through the waterproof gas-permeable membrane; and during the practical using process, when the pressure of a cavity formed between the glass panels is not equal to the outside pressure, outside air can flow between the cavity between the glass panels and the outside environment through the air holes, so that the air pressure balance inside and outside the hollow glass door is guaranteed, glass bursting accidents due to large inside and outside pressure differences are avoided, and the safe reliability of the hollow glass door is improved.

Description

technical field [0001] The invention relates to a glass door, in particular to a hollow glass door and a manufacturing method thereof. Background technique [0002] Currently, glass doors are widely used in refrigeration equipment to enhance aesthetics and visibility. In order to improve the thermal insulation performance of glass doors, hollow glass doors are usually used. Hollow glass doors are generally composed of inner glass plates, outer glass, door frames and other components. The inner and outer glass are installed on the door frame and sealed with sealant to form a hollow structure between the inner and outer glass. However, due to the influence of the temperature difference between the inside and outside of the refrigeration equipment and the influence of the actual ambient temperature and air pressure of the refrigeration equipment, the pressure in the hollow structure of the insulating glass door is likely to be unequal to the external pressure, so that the glas...
