Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a glass door and its refrigeration equipment. Background Technology

[0002] Existing display cases, refrigerators, freezers, and other refrigeration equipment typically use glass doors to facilitate the display of items inside. Based on the product's positioning, these glass doors usually have aluminum alloy or plastic frames. Plastic frames are typically made of PVC extruded material. However, glass doors made from ordinary PVC extruded profile frames have poor visual appeal and are not very aesthetically pleasing. To improve the aesthetics of the glass doors and enhance the overall appearance of the refrigeration equipment, the extruded material at the top of the glass door is replaced with injection-molded material, forming a combined frame of PVC extruded and injection-molded materials. The upper part of the door frame made of injection-molded material has rounded corners and conceals the hinges.

[0003] CN118602676A discloses a refrigerator door, refrigerator, and assembly method that are composed of injection molded parts and extruded parts. The top end cap of the refrigerator door is made by splicing multiple injection molded parts. There are splicing seams on the surface of the end cap and between the end cap and the extruded profile. The splicing seams are prone to misalignment after splicing, resulting in poor visual effect. In addition, since the end cap is made of injection molded material, each of the multiple end cap splicing parts needs to be designed and manufactured with molds separately. The design, manufacturing and debugging of injection molded parts are more expensive than using extruded parts, resulting in high production cost of glass doors. Utility Model Content

[0004] To address the problem of high production costs in existing glass doors due to the need for multiple extruded parts to be assembled, the first objective of this utility model is to provide a glass door comprising a main frame, an upper frame, a glass assembly, and a door seal. The main frame includes a lower frame profile and side frame profiles, each with a bottom groove and a side groove. The upper frame is mounted on the main frame and includes an end cap and an upper frame profile installed within the end cap. The upper frame profile and the end cap cooperate to form a top groove. The glass assembly is fixed within a frame enclosed by the top groove, bottom groove, and side grooves. The back of the main frame and the upper frame are provided with slots, and the door seal is installed in the slots.

[0005] Specifically, the end cap includes a front cover surface, a rear cover surface, an upper cover surface, and mounting portions disposed on both sides of the end cap. A first limiting plate and a second limiting plate are disposed on the inner side of the end cap.

[0006] Specifically, the front cover, rear cover, upper cover, and first limiting plate enclose a mounting cavity with a bottom opening. The upper frame profile is disposed in the mounting cavity. The upper frame profile includes a top plate and a rear fixing plate. The rear fixing plate, top plate, front cover, and second limiting plate enclose a top groove.

[0007] Specifically, the lower side of the mounting part is provided with a plurality of splicing limiting claws that match the cavities of the side frame profile, and the claws are engaged in the cavities.

[0008] Specifically, the end cap has reinforcing iron cores at both ends on its inner side, and the upper cover has reinforcing iron sheets at both ends. The reinforcing iron core includes an upper fixing part, an angle reinforcing part, and a side fixing part inserted into the cavity of the side frame profile, which are clamped between the end cap and the upper frame profile. The reinforcing iron core is connected to the upper frame and the side frame profile by screws.

[0009] Specifically, the upper fixing part of the reinforcing core is provided with a positioning groove that matches the first limiting plate and a clearance groove that matches the second limiting plate, and the positioning groove is engaged with the first limiting plate.

[0010] Specifically, the upper cover surface is provided with a baffle strip, and the reinforcing iron sheet is provided on the rear side of the baffle strip.

[0011] Specifically, the slots include a side slot on the back of the side frame profile, a bottom slot on the back of the lower frame profile, an upper slot on the back of the upper frame profile, and a corner slot on the back of the end cap.

[0012] Specifically, the front and rear sides of the bottom groove and the side groove are respectively provided with a first sealing strip and a second sealing strip, and the front side of the rear fixing plate is provided with a third sealing strip. The first sealing strip, the second sealing strip and the third sealing strip are made of soft PVC material.

[0013] The second objective of this utility model is to provide a refrigeration device, characterized in that it includes a cabinet and the aforementioned glass door, wherein the cabinet has an internal cavity, and the glass door is hinged to one side of the cabinet for opening or closing the internal cavity.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model provides a glass door and its refrigeration equipment. The frame of the glass door is assembled from an injection-molded end cap and upper frame profiles, side frame profiles and lower frame profiles made of PVC extruded material. The upper frame is formed by the upper frame profile and the end cap forming a top groove. Only a single injection-molded part is used, eliminating the need to assemble multiple injection-molded parts, which significantly reduces production costs. The assembly of the upper frame profile and the end cap is hidden in the door seal. The visible surface of the glass door has only two splicing seams on the left and right sides, resulting in an aesthetically pleasing overall appearance. Attached Figure Description
