Description

Technical Field

[0001] The utility model relates to a high-heat-insulation offline coated hollow glass door body. Background Art

[0002] The doors used in refrigerators and wine cabinets are usually hollow glass doors, which include door frames, inner glass and outer glass fixed on the door frames. Since the film layer of offline coating is easily oxidized when exposed to the air, offline coated glass is usually used for inner glass, while outer glass needs to be screen-printed. Since offline coated glass cannot be screen-printed, online coated glass is usually used for outer glass. The hollow glass door formed by the combination of offline coated glass and online coated glass has good thermal insulation performance, and its U value is generally 1.3-1.4w / m 2 .k, there is still a risk of condensation in extreme environments. Utility Model Content

[0003] In view of the above problems, the utility model provides a high-thermal insulation offline coated hollow glass door body, which effectively solves the problems pointed out in the background technology.

[0004] The technical solution adopted by the utility model is:

[0005] A high-insulation offline coated hollow glass door body comprises a door frame, and online coated glass, spacer bars and offline coated glass fixed on the door frame in sequence from the inside to the outside, the offline coated glass comprises a coating area overlapping with the online coated glass, and a frame film removal area located around the edges of the coating area, and a cavity is formed between the coating area, the spacer bars and the online coated glass.

[0006] Preferably, a silk-screen film removal area is also provided on the inner side of the offline coated glass.

[0007] Preferably, the silk-screen film removal area is located above the film coating area.

[0008] By setting the screen printing film removal area for LOGO screen printing, the LOGO printed on the offline coated glass will be clearer.

[0009] The utility model changes a hollow glass door body formed by arranging offline coated glass and online coated glass from the inside to the outside into a hollow glass door body formed by arranging online coated glass and offline coated glass from the inside to the outside, so that the offline coated glass with better thermal insulation performance is located on the outside of the hollow glass door body, thereby improving the thermal insulation performance. At the same time, in order to solve the coating oxidation problem of the offline coated glass, the laser film removal technology is used to remove the film at the frame of the offline coated glass to form a frame film removal area, so that the frame area in contact with the external air has no coating, thus avoiding the oxidation problem.

[0010] The utility model performs laser film removal at the position where the LOGO screen printing is required, so that the LOGO screen printed on the offline coated glass is clearer.

[0011] The utility model performs laser film removal on the area requiring oxidation protection and silk screen printing, retains most of the coating of the offline coated glass, and ensures that the offline coated glass still has very good thermal insulation performance.

[0012] Since the cost of offline coated glass is relatively high, the utility model adopts a combined structure of offline coated glass and online coated glass, which not only ensures the thermal insulation performance, but also reduces the U value by 10%-15% compared with the conventional hollow glass door body, and greatly reduces the cost.
