[0032] Please refer to Figure 1 , Figure 2 and Figure 3 , an embodiment of this application provides a drying filter 100, including a housing 10, a pipe body 20 and a temperature sensor 30. The housing 10 has a first inner cavity 14, and a first through hole 15 is provided on the housing 10; the pipe body 20 has a second inner cavity 23, the pipe body 20 penetrates through the first through hole 15 on the housing 10, at least a part of the pipe body 20 is located in the first inner cavity 14 of the housing 10, and moreover, the pipe body 20 is connected to the hole wall of the first through hole 15; the temperature sensor 30 is arranged in the second inner cavity 23 of the pipe body 20.

[0033] Exemplarily, the pipe body 20 can be connected to the hole wall of the first through hole 15 by welding or bonding.

[0034] The drying filter 100 provided by the embodiment of the present application is provided with a tube body 20 in the first inner cavity 14 of the housing 10 of the drying filter 100, and a temperature sensor 30 is arranged in the tube body 20, so that the temperature sensor 30 can be used to detect the temperature of the refrigerant flowing through the drying filter 100. Therefore, the condensation effect of the refrigerator condenser can be monitored, and further, the operation condition of the refrigeration system of the refrigerator can be monitored; moreover, the drying filter 100 is provided with a tube body 20 inside the housing 10, and the tube body 20 is used to accommodate and support the temperature sensor 30, so that the installation, disassembly and replacement of the temperature sensor 30 can be facilitated.

[0035] Please refer to Figure 3 , the tube body 20 has a closed end 22 and an open end 21 which are oppositely arranged. The closed end 22 is arranged in the first inner cavity 14 of the housing 10, and the open end 21 is located at the first through hole 15 or outside the housing 10. That is to say, the tube body 20 can be connected to the hole wall of the first through hole 15 with the open end 21, or connected to the hole wall of the first through hole 15 with the middle area between the open end 21 and the closed end 22.

[0036] It can be understood that by arranging the open end 21 at the first through hole 15 or outside the housing 10, the temperature sensor 30 can conveniently enter and exit the second inner cavity 23 of the tube body 20 from the open end 21, and further, the installation and disassembly of the temperature sensor 30 can be realized.

[0037] Please refer to Figure 3 , the extending direction of the housing 10 is perpendicular to the extending direction of the tube body 20.

[0038] It can be understood that when the extending direction of the housing 10 is perpendicular to the extending direction of the tube body 20, the temperature sensor 30 is arranged perpendicular to the housing 10. At this time, the temperature sensor 30 can be in full contact with the refrigerant in the central area of the housing 10, and the detected temperature of the refrigerant is relatively accurate.

[0039] In some other embodiments, the included angle between the extending direction of the housing 10 and the extending direction of the tube body 20 is an acute angle (such as 15°, 30°, 45°, 60°, 75°, 80°, etc.) or an obtuse angle (such as 105°, 115°, 135°, 150°, 165°, 170°, etc.).

[0040] It can be understood that when the included angle between the extending direction of the housing 10 and the extending direction of the pipe body 20 is an acute angle, the temperature sensor 30 is inclined relative to the housing 10. At this time, the temperature sensor 30 is relatively close to the inner wall of the housing 10. At this time, the pipe body 20 has less obstruction to the flow of the refrigerant, which is beneficial to accelerating the circulating flow speed of the refrigerant, and thus can improve the refrigeration effect of the refrigeration system of the refrigerator.

[0041] Please refer to Figure 3 , a first filter screen 41 and a second filter screen 42 are further provided in the housing 10. The first filter screen 41 and the second filter screen 42 are arranged at intervals in sequence along the extending direction of the housing 10. Both the first filter screen 41 and the second filter screen 42 are connected to the inner wall of the housing 10. The pipe body 20 is located between the first filter screen 41 and the second filter screen 42.

[0042] It can be understood that by providing the first filter screen 41 and the second filter screen 42 in the housing 10, the first filter screen 41 and the second filter screen 42 can be used to filter larger particle impurities in the refrigerant to improve the purity of the refrigerant.

[0043] Please refer to Figure 3 , a desiccant 50 is further provided in the housing 10. The desiccant 50 is arranged between the first filter screen 41 and the second filter screen 42.

[0044] It can be understood that by arranging the desiccant 50 between the first filter screen 41 and the second filter screen 42, the desiccant 50 can be concentrated in the sealed space surrounded by the first filter screen 41, the second filter screen 42 and the inner wall of the housing 10. Since the particle size of the desiccant 50 is larger than the pore size of the first filter screen 41 and the second filter screen 42, the desiccant 50 will not overflow from the pores of the first filter screen 41 and the second filter screen 42. Thus, the first filter screen 41 and the second filter screen 42 can be used to fix the desiccant 50.

[0045] Exemplarily, the desiccant 50 is a molecular sieve. Molecular sieve is an adsorbent composed of crystalline silicate (sodium aluminosilicate and calcium aluminosilicate). After removing the crystal water by heating, molecular-sized holes are formed in the crystal lattice. These holes have uniform sizes, allowing small molecules to enter the crystal but preventing large molecules from entering, thereby playing a sieving role. This characteristic makes molecular sieve an effective desiccant for gas and liquid. The functions of molecular sieve in the drying filter include: (1) Removing moisture: Molecular sieve can effectively adsorb and remove moisture from the refrigerant to ensure the normal operation of the refrigeration system. This is because the refrigerant will produce moisture during the circulation process. If it is not removed in time, it will cause ice blockage and affect the refrigeration effect; (2) Filtering impurities: In addition to removing moisture, molecular sieve can also filter various impurities in the refrigerant, such as metal powder, dirt, etc., to further ensure the purity of the refrigerant.

[0046] Exemplarily, the first filter screen 41 and the second filter screen 42 are both made of metal.

[0047] See also Figure 1 , Figure 2 and Figure 3 The shell 10 includes a cylinder 11, a first end 12 and a second end 13. The first end 12 and the second end 13 are respectively arranged at both ends of the cylinder 11 and are both connected to the cylinder 11. In the direction from the cylinder 11 to the first end 12, the cross-sectional area of ​​the first end 12 gradually decreases, and in the direction from the cylinder 11 to the second end 13, the cross-sectional area of ​​the second end 13 gradually decreases.

[0048] Exemplarily, the barrel 11 is cylindrical, and the cross-sectional area of ​​the barrel 11 remains uniform along its extension direction.

[0049] Exemplarily, the first end portion 12 and the second end portion 13 are each in a truncated cone shape.

[0050] See also Figure 3 The first filter screen 41 is located at the connection between the cylinder 11 and the first end 12 , and the second filter screen 42 is located at the connection between the cylinder 11 and the second end 13 .

[0051] See also Figure 1 , Figure 2 and Figure 3 The shell 10 also includes an inlet joint 61 and an outlet joint 62, the inlet joint 61 is connected to the end of the first end 12 away from the cylinder 11, and the outlet joint 62 is connected to the end of the second end 13 away from the cylinder 11, the cross-sectional area of ​​the inlet joint 61 is larger than the cross-sectional area of ​​the outlet joint 62, and the outlet joint 62 is used to connect to the capillary.

[0052] It is understandable that the inlet joint 61 is used to connect with the pipeline connecting the condenser.

[0053] Exemplarily, both the inlet joint 61 and the outlet joint 62 are cylindrical, and the cross-sectional areas of the inlet joint 61 and the outlet joint 62 are each kept uniform along their respective extending directions.

[0054] Exemplarily, the material of the housing 10 can be plastic, metal or ceramic, that is, the materials of the cylinder body 11, the first end portion 12, the second end portion 13, the inlet joint 61 and the outlet joint 62 can each be plastic, metal or ceramic.

[0055] Exemplarily, the housing 10 is an integral structure.

[0056] The embodiment of the present application also provides a refrigerator, including the drying filter 100 in any of the above embodiments.

[0057] Exemplarily, the refrigerator includes a refrigeration system, the refrigeration system includes a compressor, a condenser, a capillary tube and an evaporator, and the drying filter 100 is arranged between the condenser and the capillary tube.

[0058] Among them, the main function of the condenser is to cool and condense the high-temperature and high-pressure gaseous refrigerant sent by the compressor into a liquid state and release heat. This process is usually achieved through a fan or a water-cooling system so as to effectively remove the heat from the system; the function of the capillary tube is to reduce the temperature and pressure of the high-pressure liquid from the condenser. The capillary tube is usually a tube with a very small inner diameter. Due to the sudden decrease in the tube diameter and the effect of the length, the liquid will be depressurized and cooled when flowing through the capillary tube and become a low-pressure liquid refrigerant. This process is crucial for maintaining the continuous operation of the refrigeration cycle because it ensures that the refrigerant can effectively absorb heat in the evaporator, thereby achieving the refrigeration effect.

[0059] By installing the drying filter 100 between the condenser and the capillary tube in the embodiment of the present application, the main function is to remove the residual moisture in the refrigerant, prevent ice blockage, and reduce the corrosion effect of moisture on the refrigeration system; at the same time, the drying filter 100 can also filter out impurities in the refrigeration system, such as dust, metal chips and various oxides, to prevent the impurities from blocking the capillary tube or damaging the compressor; in addition, the drying filter 100 provided in the embodiment of the present application further includes a temperature sensor 30, so that the temperature of the refrigerant flowing through the drying filter 100 can be detected by using the temperature sensor 30. Therefore, the condensation effect of the refrigerator condenser can be monitored, and further, the operation condition of the refrigeration system of the refrigerator can be monitored.

[0060] The above has introduced in detail the drying filter and the refrigerator provided by the embodiments of the present application. Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only for helping to understand the present application. At the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
