Description

Technical Field

[0001] This application relates to the field of refrigeration equipment, and more specifically, to a dryer filter and its refrigeration equipment. Background Technology

[0002] There are many types of refrigeration equipment, which are commonly used in daily life and production. Among them, refrigerators and air conditioners, which are common in daily life, are refrigeration equipment. The main refrigeration components in refrigeration equipment include compressors, condensers, expansion valves, and evaporators. In order to improve the refrigeration effect and the service life of the components, a dryer filter is usually installed in front of the expansion valve for drying and filtration. The dryer filter is mainly used to dry the moisture in the refrigerant and filter the impurities in the refrigerant.

[0003] The interior of a dryer filter contains a filter screen and a molecular sieve. As the usage time increases, the filtration and drying effect of the filter screen and molecular sieve will decrease. However, in the relevant dryer filter technology, the shell of the dryer filter is welded as a whole, making it difficult to disassemble the dryer filter shell, which makes it inconvenient to replace the molecular sieve and clean the filter screen. Therefore, when the dryer filter loses its filtration and drying effect, it is usually replaced directly, which is costly. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a dryer filter and its refrigeration device, which aims to improve the problems of inconvenience in replacing molecular sieves and cleaning filter screens, resulting in high costs.

[0005] In a first aspect, embodiments of this application provide a drying filter, including a drying filter assembly.

[0006] The drying and filtration assembly includes a first housing, a second housing, a cylinder, a first threaded sleeve, a second threaded sleeve, a first filter plate, a second filter plate, and a molecular sieve. The cylinder is slidably inserted between the first housing and the second housing. The first threaded sleeve is threadedly fitted onto the top of the cylinder and onto the outside of the first housing. The second threaded sleeve is threadedly fitted onto the bottom of the cylinder and onto the outside of the second housing. Handwheels are provided on the outside of both the first and second threaded sleeves. The first filter plate is fixedly connected to the inside of the cylinder. The second filter plate is magnetically attracted to the inside of the cylinder. A handle is provided on the upper surface of the second filter plate. The molecular sieve is placed inside the cylinder.

[0007] In one specific implementation, the top wall of the cylinder is slidably attached to the bottom wall of the first housing, and the bottom wall of the cylinder is slidably attached to the top wall of the second housing.

[0008] In one specific implementation, a first limiting plate is fixedly sleeved on the outside of the first housing, a first sealing gasket is provided on the bottom wall of the first limiting plate, and the top wall of the first threaded sleeve abuts against the first sealing gasket.

[0009] In one specific implementation, a second limiting plate is fixedly sleeved on the outside of the second housing, a second sealing gasket is provided on the top wall of the second limiting plate, and the bottom wall of the second threaded sleeve abuts against the second sealing gasket.

[0010] In one specific implementation, a limiting ring is provided inside the top of the cylinder, a first annular magnet is provided on the upper surface of the limiting ring, and a second annular magnet is provided on the lower surface of the second filter plate, the second annular magnet being magnetically attracted to the first annular magnet.

[0011] In one specific implementation, two handles are provided, which are symmetrically arranged and both handles are located at the edge of the upper surface of the second filter plate.

[0012] In one specific embodiment, the molecular sieve is placed above the first filter plate, and the molecular sieve is located between the first filter plate and the second filter plate.

[0013] Secondly, embodiments of this application also provide a refrigeration device, including the aforementioned drying filter and refrigeration components.

[0014] The refrigeration assembly includes a compressor, a condenser, an expansion valve, and an evaporator. The refrigerant outlet of the compressor is connected to the refrigerant inlet of the condenser. The refrigerant outlet of the condenser is connected to the first housing. The second housing is connected to the refrigerant inlet of the expansion valve. The refrigerant outlet of the expansion valve is connected to the refrigerant inlet of the evaporator. The refrigerant outlet of the evaporator is connected to the refrigerant inlet of the compressor.

[0015] In one specific implementation, the outlet of the compressor refrigerant is connected to the inlet of the condenser refrigerant via a first pipe, the outlet of the condenser refrigerant is connected to the first housing via a second pipe, the second housing is connected to the inlet of the expansion valve refrigerant via a third pipe, the outlet of the expansion valve refrigerant is connected to the inlet of the evaporator refrigerant via a fourth pipe, and the outlet of the evaporator refrigerant is connected to the inlet of the compressor refrigerant via a fifth pipe.

[0016] The beneficial effects of this utility model are as follows: When using the dryer filter and its refrigeration equipment obtained through the above design, if it is necessary to clean the first and second filter plates or replace the molecular sieve, rotating the two handwheels will rotate the first and second threaded sleeves. The first threaded sleeve moves away from the first housing, and the second threaded sleeve moves away from the second housing, thus separating the first and second threaded sleeves from the first and second housings. The cylinder can then be pulled out from between the first and second housings, completing the disassembly of the cylinder. The second filter plate can then be pulled out of the cylinder by the handle, and the molecular sieve can be poured out from the cylinder, allowing for cleaning of the first and second filter plates and replacement of the molecular sieve. This makes cleaning the first and second filter plates and replacing the molecular sieve more convenient, eliminating the need to replace the dryer filter and saving costs.

[0033] Please see Figure 1 This application also provides a refrigeration device, including the above-mentioned dryer filter and refrigeration component 200.

[0034] Please see Figure 1 and 2 The refrigeration assembly 200 includes a compressor 210, a condenser 220, an expansion valve 230, and an evaporator 240. The refrigerant outlet of the compressor 210 is connected to the refrigerant inlet of the condenser 220, and the refrigerant outlet of the compressor 210 and the refrigerant inlet of the condenser 220 are connected through a first pipe 250.

When cleaning the first filter plate 160 and the second filter plate 170 is required, or when replacing the molecular sieve 180 is required, the two handwheels 190 are rotated, which in turn rotates the first threaded sleeve 140 and the second threaded sleeve 150. The first threaded sleeve 140 moves away from the first sealing gasket 112, and the second threaded sleeve 150 moves away from the second sealing gasket 122, thereby allowing the first... A threaded sleeve 140 can be separated from the first housing 110, allowing the second threaded sleeve 150 to separate from the second housing 120. The cylinder 130 can then be pulled out from between the first housing 110 and the second housing 120, thus completing the disassembly of the cylinder 130. The second filter plate 170 can then be pulled out of the cylinder 130 by holding the handle 171, allowing the molecular sieve 180 to be poured out. This facilitates the cleaning of the first filter plate 160 and the second filter plate 170, and the replacement of the molecular sieve 180. Consequently, the dryer filter does not need to be replaced, saving costs.
