Description

Technical Field

[0001] This utility model relates to the field of fuze technology, specifically a refrigerated dryer cabinet. Background Technology

[0002] A refrigerated air dryer, also known as a freeze dryer, is a device that uses refrigeration technology to lower the temperature of compressed air, thereby reducing the water vapor content in the air. It is widely used in industrial production to provide dry, clean compressed air. Its working principle involves cooling the compressed air to below its dew point temperature through a refrigeration system, causing the water vapor in the air to condense into liquid water, which is then discharged through a drainage system. It typically includes an evaporator, condenser, and refrigeration compressor. The air dryer cabinet houses these components. However, in daily use, the following problems exist: due to external environmental factors (temperature and humidity changes), a certain amount of condensation sometimes occurs inside the cabinet, resulting in high internal humidity, which is detrimental to the long-term stable operation of electrical equipment. Furthermore, routine maintenance of the electrical structure requires opening the cabinet, which is inconvenient. In addition, the refrigerated air dryer cabinet is equipped with a grille for air intake and exhaust. During use, a large amount of dust will accumulate in the grille, which can easily affect its working efficiency. In practice, this is usually solved by regular cleaning. There are also related patents, such as patent CN221867808U, a refrigerated air dryer that is easy to clean. This patent uses a screw and nut structure to drive the cleaning structure to clean the grille, which will significantly increase the cost of the cabinet. Moreover, the screw and nut are also easily affected by dust, making them unable to move smoothly or even jam. Summary of the Invention

[0003] The purpose of this utility model is to provide a refrigerated dryer cabinet to solve the problems existing in the prior art.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] As attached Figure 1-5 As shown, the refrigerated dryer cabinet involved in this utility model includes a main cabinet body 1, an electrical box 2, and a foot unit 3.

[0019] The main cabinet 1 is a hollow rectangular box structure made of metal sheet, with a grille 11 on one side, which is an array of air passage holes.

[0020] An opening 12 is provided on one side of the main cabinet 1, and an electrical box 2 is provided at the opening 12. The electrical box 2 is box-shaped and has an opening on the side parallel to the side of the main cabinet 1 where the opening 12 is provided. The electrical box 2 extends into the interior of the main cabinet 1 through the opening 12, and its edge is fixedly connected to the opening 12. A wire through hole 21 is provided on the electrical box 2. The electrical box 2 may also be provided with a box cover 22 that can seal its opening.

[0021] The main cabinet 1 is provided with a foot unit 3 below it. The foot unit 3 includes several support feet 31 and a horizontal support plate 32. The support feet 31 are located at the lower part of the horizontal support plate 32. The main cabinet 1 is located on the horizontal support plate 32. The foot unit 3 can be installed or its size can be adjusted as needed. The support feet 31 can be plate-shaped or column-shaped. The figure shows a plate-shaped support feet.

[0022] As attached Figure 4 , 5 As shown, the air passage f of the grille 11 is a rounded rectangular hole.

[0023] The refrigerated dryer cabinet also includes a dust removal structure 4, which includes a limiting groove 41 and a dust removal plate 42. The dust removal plate 42 includes an inner insert plate 421, a horizontal connecting plate 422, a vertical connecting plate 423, and a hand handle 424.

[0024] The inner insert plate 421 is inserted into the air passage hole f. Its lateral dimension is smaller than that of the air passage hole f. Its number and position distribution are consistent with the multiple arrays of air passage holes f of the grille 11, so that each air passage hole f is provided with an inner insert plate 421. The length of the inner insert plate 421 is greater than or equal to the thickness of the plate at the air passage hole f.

[0025] The horizontal connecting plate 422 is used to connect several inner insert plates 421 in a horizontal row.

[0026] The vertical connecting plate 423 is disposed on both sides of the horizontal connecting plate 422 and is used to connect several horizontal connecting plates 422. There are at least two vertical connecting plates 423, and there may be more than one.

[0027] Hand-held levers 424 are provided on the vertical connecting plates 423 on both sides. One end of the hand-held lever 424 is perpendicular to the vertical connecting plate 423, passes through the limiting groove 41 and bends to one side, thereby preventing it from falling out of the limiting groove 41.

[0028] The limiting groove 41 is set on the side plate of the main unit cabinet on both sides of the grille opening, and its vertical dimension is larger than the longitudinal dimension of the air passage hole f.

[0029] The dust removal plate 42 is formed by stamping and bending in one go. Alternatively, the inner insert plate 421 and the horizontal connecting plate 422 can be formed by stamping and bending a single sheet of material, and then connecting it with the vertical connecting plate 423.

[0030] During assembly, insert the inner plate 421 into the air passage hole f, and bend the handle 424 to one side after passing through the limiting groove 41. When in use, hold the ends of the handle 424 with both hands and move the dust removal plate 42 up and down. This can compress the dust in the air passage hole f to both sides, making it easier to clean. This can significantly improve cleaning efficiency and reduce dust generation.

[0031] It should be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.
