Glass door, manufacturing technique and refrigeration equipment

Abstract

The invention provides a glass door which comprises an outer glass sheet, an inner glass sheet and a spacing bar. The outer glass sheet is separated from the inner glass sheet through the spacing bar, and a hollow space is formed. The spacing bar is located on the periphery of the hollow space. The outer side of the spacing bar is located between the outer glass sheet and the inner glass sheet, and the outer glass sheet and the inner glass sheet are bonded through a sealant. A PU frame is arranged on the outer side of the sealant. The PU frame wraps the periphery of the inner glass sheet or wraps the periphery of the inner glass sheet and the periphery of the outer glass sheet at the same time. The invention further provides a manufacturing technique of the glass door and refrigeration equipment adopting the glass door. Integrated formation of a door body is achieved by combining the PU and the RIM technique, the hollow glass sheets are sealed into an integral module through the PU material, and the undesirable odor problem of a sealant of a hollow glass door is solved; meanwhile, condensation of a frame can be prevented; and by the adoption of the integral forming technique, a few hours of curing time of the hollow glass sheets and the frame is shortened, the product takt time is shortened, and the production quality is improved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to a glass door, a preparation process and refrigeration equipment. Background technique [0002] At present, the insulating glass door body used for refrigeration equipment is generally two-layer insulating glass or three-layer insulating glass bonded or plugged into the frame to form a door assembly. Taking two-layer insulating glass as an example, the structure can be found in figure 1 As shown: the hollow glass door body includes outer glass a and inner glass b, the outer glass a and the inner glass b are separated by a spacer c, and sealed with two layers of glue, the first sealant d is Butyl glue, the second sealant e is silicone glue, and then the door body frame f (extruded frame, injection frame or aluminum alloy frame) is plugged and assembled with insulating glass, and bonded with sealant g. Wherein the sealant g and the second sealant are of ...

AI Technical Summary

Problems solved by technology

[0004] 1. The sealant (usually silicone glue, polysulfide glue, etc.) has a long curing time. After the insulating glass and the frame are bonded and fixed, they need to be fixed with tooling. It can be basically fixed after 3-4 hours. Remove the tooling and wait for 24 hours. The above can be fully cured, and the production cycle is slow

[0005] 2. The sealant has a very strong odor. After it is installed on the refrigeration equipment, there will be a strong odor permeating in the box of the refrigeration equipment (ice bar, wine cabinet, beverage cabinet, etc.), which not only affects the user's experience of opening the door, but also affects the inside of the box. food storage

[0007] 4. The process is complicated, the manual installation and coating cycle is slow, and it is not environmentally friendly
