Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, and in particular to a refrigerator purification device and a detection method. Background Art

[0002] Refrigerators store a wide variety of ingredients, all of which can generate a variety of odors. Furthermore, low temperatures, high humidity, and high bacterial metabolism make it easier for bacteria to produce odors. These odors not only affect the flavor of the ingredients themselves but also create a poor user experience. The constant growth of bacteria inside the refrigerator can also affect user health.

[0003] Refrigerator purification devices primarily utilize activated carbon, ion generators, photocatalysis, and other technologies to remove odors, bacteria, and impurities from the environment. In some embodiments, refrigerator purification devices are placed in air ducts or compartments, utilizing the air flow within the refrigerator to achieve odor removal and sterilization. However, if placed within the air duct, the inherent yield rate of the electrical components and the device assembly process may result in errors, leading to damage or loss of functionality. Furthermore, since the UV lamp is installed within the air duct, it emits invisible light and cannot be detected by the human eye. This also prevents online real-time testing and verification. Functional verification requires disassembly, significantly impacting production efficiency and hindering product quality control. In other embodiments, refrigerator purification devices can detect the temperature of the UV lamp assembly. However, they cannot determine core functional indicators such as UV intensity. None of these approaches address the problem of inability to perform real-time online evaluation of the purification device during mass production of refrigerators, hindering product yield. This can lead to constant retesting and misjudgment on the production line, impacting production efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0053] The following embodiments are described in detail, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numbers in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following embodiments are not intended to represent all possible implementations consistent with the present application. They are merely examples of systems and methods consistent with certain aspects of the present application, as detailed in the claims.

[0054] Refrigerator purification devices primarily utilize activated carbon, ion generators, photocatalysis, and other technologies to remove odors, bacteria, and impurities from the environment. In some embodiments, refrigerator purification devices are placed in air ducts or compartments, utilizing the air flow within the refrigerator to achieve odor removal and sterilization. However, if placed within the air duct, the inherent yield rate of the electrical components and the device assembly process may result in errors, leading to damage or loss of functionality. Furthermore, since the UV lamp is installed within the air duct, it emits invisible light and cannot be detected by the human eye. This also prevents online real-time testing and verification. Functional verification requires disassembly, significantly impacting production efficiency and hindering product quality control. In other embodiments, refrigerator purification devices can detect the temperature of the UV lamp assembly. However, they cannot determine core functional indicators such as UV intensity. None of these approaches address the problem of inability to perform real-time online evaluation of the purification device during mass production of refrigerators, hindering product yield. This can lead to constant retesting and misjudgment on the production line, impacting production efficiency.

[0055] In order to solve the problem that the purification performance of a refrigerator purification device cannot be directly detected, an embodiment of the present application provides a refrigerator purification device and a detection method.

[0056] like Figure 1 and Figure 6 As shown, some embodiments of the present application provide a refrigerator purification device, including: a lamp box 11, a purification lamp 12, an air inlet box 13, a catalyst 14, a fan 15, an air outlet cover 16, a detection unit and a control panel 22.

[0057] The lamp box 11, the purification lamp 12, the air inlet box 13, the catalyst 14, the fan 15, and the air outlet cover 16 are connected in sequence; the detection unit is arranged between the air outlet cover 16 and the fan 15; the control board 22 is respectively communicated with the purification lamp 12, the fan 15 and the detection unit.

[0058] It should be understood that when the fan 15 is working, the air flow inside the refrigerator enters from the air inlet 1312 of the air inlet box 13, passes through the catalyst 14 and the fan 15, and flows out from the air outlet 161 of the air outlet cover 16.

[0059] The refrigerator purification device can achieve purification by blowing the charged ions generated by the purification lamp 12 irradiating the catalytic medium 14 into the interior of the refrigerator through the fan 15. The refrigerator purification device can be independently arranged inside the refrigerator without being constrained by other air duct spaces, which is convenient for product testing and can meet the needs of mass production, testing, and judgment of the production line.

[0060] like Figure 7 、 8 As shown in FIG. 11 , the detection unit includes a detection card 31 and a color card 32; the control board 22 is configured as follows:

[0061] S100: Control to turn on the purification lamp 12 and the fan 15.

[0062] S200 : After the photosensitive area 310 of the detection card 31 enters the preset detection area of ​​the air inlet box 13 , the chromaticity value detected by the detection card 31 is obtained.

[0063] S300: Compare the chromaticity value detected by the detection card 31 with the color card 32 to generate a light beam intensity value.

[0064] S400: If the light beam intensity value exceeds a set value, marking the refrigerator purification device as a qualified product;

[0065] S500: If the light beam intensity value does not exceed the set value, mark the refrigerator purification device as unqualified.

[0066] It should be understood that the preset detection area is the irradiation area of ​​the purification lamp 12 in the connection surface between the air outlet cover 16 and the fan 15. The preset detection area is free of other interferences, and can truly measure the light beam intensity value of the refrigerator purification device, making the detection more accurate. The light beam is an ultraviolet light beam, which has a strong sterilization effect. The control board 22 can use a single-chip microcomputer. There is a blank photosensitive area 310 on the detection card 31, which can sense the changes in the intensity of the light beam emitted by the purification lamp 12 and present corresponding dark and light colors. There is a table of light beam intensity values ​​corresponding to different colors on the color card 32. The light beam intensity value on the color card 32 is matched according to the color detected by the detection card 31, thereby judging the light beam intensity.

[0067] By controlling the chromaticity value obtained by the detection card 31 in the preset detection area to be compared with the color card 32, a beam intensity value is generated to judge whether the refrigerator purification device is qualified, thereby solving the problem that the refrigerator purification device cannot directly detect the purification performance.

[0070] In some embodiments, a wire hole 111 is provided on a side of the lamp box 11 away from the air inlet box 13 , and the wires of the lamp box 11 pass through the wire hole 111 to connect to the purification lamp 12 , the fan 15 and the control board 22 .

[0071] The wire holes 111 are used to connect the purification lamp 12 , the fan 15 , the control panel 22 and the external power supply to each other through the wires, thereby realizing the function of powering and controlling the purification device.

[0074] In some embodiments, a fixing platform 113 is provided inside the cavity of the lamp box 11; the fixing platform 113 includes supporting ribs 1131, light board limiting ribs 1132 and light board clamping claws 1133; the light board 122 includes a first light board surface 1221, a second light board surface 1222 and a third light board surface 1223; the supporting ribs 1131 are in contact with the first light board surface 1221; the light board limiting ribs 1132 are in contact with the second light board surface 1222; the light board clamping claws 1133 are clamped with the third light board surface 1223.

[0075] The supporting ribs 1131 are used to support the light board 122, the light board limiting ribs 1132 are used to limit the displacement of the light board 122, and the light board claws 1133 are used to fix the light board 122 inside the cavity of the light box 11, thereby reducing the occurrence of damage to the refrigerator purification device caused by the displacement or falling of the light board 122.

[0076] like Figure 4 As shown, in some embodiments, the air inlet box 13 is a cavity structure; the air inlet box 13 includes a limiting rib 1311, a catalytic medium chamber 1313, a catalytic medium claw 13131 and an air inlet hole 1312; a plurality of the air inlet holes 1312 are evenly arranged on the back side 131 of the air inlet box; the limiting rib 1311 is located at the corner of the back side 131 of the air inlet box; the catalytic medium chamber 1313 is located in the middle of the back side 131 of the air inlet box; the two catalytic medium claws 13131 are symmetrically arranged on both sides of the catalytic medium chamber 1313.

[0077] The limiting rib 1311 is used to form a gap with the inner tank; the air inlet is used to form an air inlet channel to facilitate wind field circulation; the catalytic medium claw 13131 is used to fix the catalytic medium 14; and the catalytic medium chamber 1313 is used to place the catalytic medium 14.

[0078] In some embodiments, the catalytic medium 14 is a photocatalyst medium; the catalytic medium 14 is fixed in the catalytic medium chamber 1313 by the catalytic medium claws 13131 .

[0079] The light beam generated by the lamp bead 121 of the purification lamp 12 irradiates the catalyst 14, which can generate a large amount of negative ions, thereby oxidizing and decomposing the pollutants in the box, achieving the effect of sterilization and deodorization.

[0083] The air outlet 161 allows the airflow passing through the fan 15 to flow out. The buckle 162 is used to connect the air outlet cover 16 and the air inlet box 13 to facilitate disassembly.
