Hollow glass door and manufacturing method thereof

Abstract

The invention provides a hollow glass door and a manufacturing method thereof. The hollow glass door include a frame, an outer glass plate, an inner glass plate, and an air pressure balancing assembly; the outer glass plate and the inner glass plate are arranged on the frame; the air pressure balancing assembly includes a sealing partition bar and waterproof breathable film; the sealing partition bar is clamped between the outer glass plate and the inner glass plate; a plurality of vent holes are formed in the sealing partition bar; the waterproof breathable film is pasted on the sealing partition bar and covers the vent holes; the vent holes are covered by the waterproof breathable film; in actual use, when the pressure of a cavity formed between the glass plates is not equal to the ambient pressure, outside air can flow between the cavity and the outside environment through the vent holes, and then the air pressure in the hollow glass door and the air pressure outside the hollow glass door can be balanced, glass burst accidents due to over-high pressure difference can be avoided, and the safety and reliability of the hollow glass door can be 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...

Problems solved by technology

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 glass of the insulating glass door is likely to be deformed or damaged due to the pressure difference. Burst, resulting in lower safety reliability of the hollow glass door in the prior art
