Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a door body for refrigeration equipment. Background Art
[0002] Refrigeration equipment refers to equipment that can remove heat from one place and transfer it to another place, usually used to keep the temperature of a certain space or object lower than the surrounding environment temperature. Refrigeration equipment can be various, from simple household refrigerators to complex industrial cooling systems.
[0003] Common types of refrigeration equipment with a combination of a chassis and a door are as follows:
[0004] Household refrigerators and freezers: These are the most common refrigeration equipment, used to store food and other items in a low-temperature environment to prevent them from spoiling.
[0005] Commercial freezers: Freezers used in commercial environments, such as display cabinets in supermarkets and cold storages in the catering industry, for storing and displaying food.
[0006] Medical refrigeration equipment: Such as medical refrigerators, drug refrigerators, etc., used to store drugs, vaccines and other medical supplies, with strict requirements for temperature control.
[0007] The working principle of refrigeration equipment is usually based on the vapor compression refrigeration cycle, using the heat absorption and heat release characteristics of the refrigerant in different states to achieve heat transfer. In some special application scenarios, such as ultra-low temperature freezing, other types of refrigeration technologies may also be used, such as absorption refrigeration or semiconductor refrigeration.
[0008] Currently, for the door body structure of refrigeration equipment, in most cases, the door body is still set to rotate horizontally mainly. The form of a vertically opening door can better place the frozen objects into the refrigeration equipment. However, for most small refrigeration and cold storage equipment, their door bodies are mainly of a single-layer heat insulation structure. When used for a long time, if the outside is relatively hot, there are still many cases of internal and external heat exchange, which causes the refrigeration equipment to continuously work without being able to stop and rest, resulting in a reduced service life of the refrigeration equipment and continuous power consumption.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0027] Refer to Figures 1-4, A door body for a refrigeration device, comprising a door panel 10, a handle 11 is provided on the outer side of the door panel 10, and one end of the handle 11 is fixedly assembled with the surface of the door panel 10 by screws. On the other side of the door panel 10, there is an inner lining plate 12. A sealing strip 13 is provided at the connecting edge between the inner lining plate 12 and the door panel 10. The sealing strip 13 is adhesively fixed to the surface of the door panel 10 by resin glue, and the sealing strip 13 is tightly fitted with the edge of the inner lining plate 12. A concave storage groove 14 is formed on the surface of the inner lining plate 12. On one side of the door panel 10, there are two hinge sleeves 15 of the same specification, and one end of the hinge sleeve 15 is fixedly assembled with the surface of the door panel 10 by screws. The number of hinge sleeves 15 is two, and the two hinge sleeves 15 are symmetrically distributed along the vertical position of one side edge of the door panel 10. Inside the door panel 10, there are filled with a first thermal insulation layer 16, a heat insulation layer 17 and a second thermal insulation layer 18 respectively. The first thermal insulation layer 16, the heat insulation layer 17 and the second thermal insulation layer 18 are adhesively fixed to each other by resin glue.
[0028] Further, it should be noted that the sealing strip 13 is made of rubber material, and it has:
[0029] Good sealing performance: Rubber material has good elasticity and sealing property, which can effectively prevent air, water, dust, etc. from penetrating through the sealed area;
[0030] Weather resistance: Rubber sealing strips usually have good weather resistance, can resist the influence of environments such as ultraviolet rays, high temperature, and low temperature, and are not easy to age;
[0031] Corrosion resistance: Rubber sealing strips have certain corrosion resistance to a variety of chemical substances, such as grease, acid, alkali, etc.
[0032] Economical and durable: Compared with other sealing materials, rubber sealing strips usually have a moderate price and a long service life, with a high cost performance.
[0033] Further, it should be noted that the number of storage grooves 14 is at least four, and the storage grooves 14 are equally spaced along the vertical position of the inner lining plate 12, which can accommodate some small items for refrigeration and reduce the position where small items occupy the space for placing large items.
[0034] Further, it should be noted that two hook grooves 20 are formed on one side of the door panel 10, and the hook grooves 20 are distributed along the vertical position of the door panel 10. On one side of the inner lining plate 12, there is a hook 21 integrally formed and fixedly attached. The hook 21 is hung in fit with the hook groove 20, which can facilitate the quick disassembly and assembly of the inner lining plate 12 from the door panel 10 when regular cleaning is required. Moreover, the inner lining plate 12 itself is made of high-strength plastic material, which increases the thickness of the central area of the door panel 10 and forms an auxiliary heat insulation effect in disguise.
[0035] Further, it should be noted that the first thermal insulation layer 16 is made of vacuum insulation panel material, which is a new type of thermal insulation material composed of a core material and a packaging bag. The packaging bag is evacuated, greatly reducing the heat transfer rate. Due to its small size and light weight, it is particularly suitable for refrigerators with limited space.
[0036] Further, it should be noted that the heat insulation layer 17 is made of polyurethane foam material, which has good heat insulation performance and a closed-cell structure, and can effectively prevent moisture penetration and heat transfer.
[0037] Further, it should be noted that the second thermal insulation layer 18 is made of aluminosilicate fiber board material, which has good heat insulation effect and fire resistance.
[0038] Working mode: Through the three layers of heat insulation materials filled inside the door panel 10, the heat insulation structure is no longer single, improving the closed heat insulation effect when the door panel 10 is installed with the cabinet or box body of the refrigeration and cold storage equipment. Through the hinge sleeve 15 structure installed on the edge of the door panel 10, it can be assembled with the hinge parts adaptable to the cabinet or box body, and the stable opening and closing of the door panel 10 can be realized.
[0039] Through the inner lining plate 12 structure, it can have the effect of assisting heat insulation. At the same time, the storage slots 14 opened on the inner lining plate 12 can be used to store small items, improving the bearing area range in the closed environment after the door panel 10 is installed with the cabinet or box body.
[0040] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
