[0032] Figure 1 is a schematic structural diagram of a purification component provided by the embodiments of the present utility model.Figure 2 It is a schematic exploded view of the purification component provided by the embodiment of the present utility model.

[0033] Refer to Figure 1 and Figure 2 The embodiment of the present utility model provides a purification component 200. The purification component 200 can be applied to a refrigerator, but is not limited to being applied to a refrigerator, and can be applied to occasions or devices that require odor removal and purification, such as odor eliminators, purifiers, fresh-keeping warehouses, etc. The purification component 200 includes a housing 210 and a purification component.

[0034] The housing 210 includes a carrier 213 and a cover 214. The carrier 213 and the cover 214 can be connected in a snap-fit manner, that is, a convex structure is provided on one of the carrier 213 and the cover 214, and a card slot is provided on the other of the carrier 213 and the cover 214. When the cover 214 is covered on the carrier 213, the snap connection is realized through the cooperation of the card slot and the convex structure. The carrier 213 and the cover 214 can also be detachably connected by means of fasteners such as screws.

[0035] The carrier 213 can be set to a rectangular shape, a square shape or other shapes. A positioning groove can be provided inside the carrier 213. When the cover 214 is covered on the carrier 213, the positioning groove is closed to form a receiving cavity 211, and part of the structure of the purification component can be embedded in the receiving cavity 211, such as the power device 230 described below.

[0036] The cover 214 includes a main body 2141 and an extension 2142. The extension 2142 extends outward from one side of the main body 2141, which is equivalent to the extension 2142 protruding from the surface of the main body 2141. The shape of the main body 2141 is adapted to the shape of the carrier 213, and the main body 2141 and the carrier 213 are detachably connected. An ionization channel 212 is provided on the extension 2142, and the ionization channel 212 communicates with the receiving cavity 211. When the purification component 200 is installed in the air duct of the refrigeration device, the ionization channel 212 communicates with the air duct, so that the air flow passing through the air duct can be ionized in the ionization channel 212 to achieve air purification.

[0037] The purification component includes a power supply device 230 and an electrode component 240. The electrode component 240 is electrically connected to the power supply device 230. The power supply device 230 is disposed in the accommodation cavity 211, and the electrode component 240 extends into the ionization channel 212. The electrode component 240 includes a first electrode 241 and a second electrode 242. The first electrode 241 and the second electrode 242 are arranged at intervals. A discharge part 2411 is provided on the side of the first electrode 241 facing the second electrode 242. The discharge part 2411 protrudes relative to the main body structure of the first electrode 241. The second electrode 242 is provided with a receiving part 2421. The position of the receiving part 2421 corresponds to the position of the discharge part 2411, and the receiving part 2421 is provided with an opening.

[0038] When the air in the space where the purification assembly 200 is located enters the purification assembly 200 and reaches the positions where the first electrode 241 and the second electrode 242 are located, the power supply device 230 supplies current to the first electrode 241 and the second electrode 242. Ionization discharge can occur between the first electrode 241 and the second electrode 242 to generate high-concentration ozone or high-energy electrons, negative ions, excited state particles and strongly oxidizing free radicals between the first electrode 241 and the second electrode 242. The highly active free radicals can degrade odors and bacteria, so that the large odor molecules are degraded into short-chain small molecules, which belongs to a process of pre-treating odors.

[0039] It can be understood that for the purification assembly 200 provided by the embodiment of the present invention, by arranging a purification component in the housing 210, the purification component includes a power supply device 230 and an electrode component 240. The electrode component 240 includes a first electrode 241 and a second electrode 242. The first electrode 241 and the second electrode 242 are arranged at intervals. A discharge part 2411 is provided on the side of the first electrode 241 facing the second electrode 242. The second electrode 242 is provided with a receiving part 2421. The position of the receiving part 2421 corresponds to the position of the discharge part 2411, and the receiving part 2421 is provided with an opening. Equivalently, the receiving part 2421 of the second electrode 242 is a semi-closed structure. Compared with a closed hole electrode, such a setting can avoid the formation of a water curtain or ice on the receiving part 2421 of the second electrode 242, improve the reliability of the electrode, and ensure that the purification assembly 200 has a good purification effect.

[0040] Figure 3 It is a schematic structural diagram of the purification component in the purification assembly 200 provided by the embodiment of the present invention.

[0041] Continue to refer to Figure 2 and at the same time refer to Figure 3 In some embodiments of the present invention, the discharge part 2411 is a needle tip structure, that is, the first electrode 241 is a needle tip electrode, and the projection of the discharge part 2411 on the second electrode 242 is located on the axis of the receiving part 2421.

[0042] The receiving part 2421 can be a circular or polygonal hollow structure, with an opening formed on one side of the receiving part 2421, so that the circular or polygonal hollow structure is not a closed structure. The opening can be arranged on the extension line of the center line of the receiving part 2421, or can be arranged offset from the extension line of the center line of the receiving part 2421.

[0043] With such a setting, the discharge part 2411 of the needle tip structure can concentrate the electric field intensity, so that a high-intensity electric field region is formed near the needle tip. This high-intensity electric field is conducive to the occurrence of ionization discharge, improving the discharge efficiency, and thus generating more active substances, such as ozone, negative ions, etc., for air purification. And the position of the receiving part 2421 is corresponding to the position of the discharge part 2411, so that the receiving part 2421 and the needle tip structure form a good cooperation to jointly form a discharge region, optimize the discharge path, and improve the discharge efficiency and energy utilization efficiency.

[0044] Further, the axis of the receiving part 2421 is collinear with the center line of the opening. That is, the opening is arranged on the extension line of the center line of the receiving part 2421. At this time, the shapes of the receiving part 2421 and the opening that cooperate with each other are similar to a "U"-shaped long groove, and the "U"-shaped long groove is arranged along the width of the second electrode 242. With such a setting, the electric field intensity can be concentrated to the maximum extent, optimizing the discharge effect.

[0045] Continue to refer to Figure 2 and Figure 3 , in some embodiments of the present invention, the plane where the first electrode 241 is located and the plane where the second electrode 242 is located are perpendicular to each other. With such a setting, the discharge part 2411 can extend along the width direction of the first electrode 241, which is convenient for the processing of the discharge part 2411 and is also convenient for the first electrode 241 and the second electrode 242 to cooperate to form an ionization field.

[0046] In addition, in some embodiments, in addition to setting a long groove at the position of the second electrode 242 corresponding to the discharge part 2411, other structures can also be set, such as a receiving needle tip structure or a fin structure, as long as the discharge for generating ozone or ions can be realized between the discharge part 2411 and the second electrode 242. Therefore, in an embodiment of the present invention, the discharge part 2411 can be a needle tip structure, and the second electrode 242 is provided with a receiving needle tip structure corresponding to the needle tip structure, and the receiving needle tip structure faces the first electrode 241.

[0047] With such a setting, for the relatively arranged needle tip structure and the receiving needle tip structure, the discharge is concentrated between the needle tip structure and the receiving needle tip structure, which can effectively increase the ionization air efficiency, and thus increase the quantity of active substances generated by ionization.

[0048] Continue to refer to Figure 3, in some embodiments of the present utility model, a second heating element 260 is provided between the first electrode 241 and the second electrode 242. The second heating element 260 is used to generate heat to increase the temperature at the positions where the first electrode 241 and the second electrode 242 are located, thereby preventing the first electrode 241 and the second electrode 242 from condensing or freezing due to low temperature.

[0049] Furthermore, the second heating element 260 can be arranged at a position close to the first electrode 241, so as to provide heat for the first electrode 241 to effectively prevent the first electrode 241 from condensing or freezing. Since there is an opening on the second electrode 242, a water curtain or condensation generally does not form at the position of the opening. Therefore, compared with the first electrode 241, the generation of this phenomenon can be alleviated. Thus, the second heating element 260 is arranged at a position close to the first electrode 241 to effectively prevent condensation or freezing on the surface of the first electrode 241.

[0050] Continue to refer to Figure 2 and Figure 3 , in some embodiments of the present utility model, the duty ratio of the power supply device 230 is <50%. The power supply device 230 includes a high-voltage transformer 231, a low-voltage input circuit 232, and a high-voltage output circuit 233 provided on the circuit board 220. The low-voltage input circuit 232 is connected to the input end of the high-voltage transformer 231, and the high-voltage output circuit 233 is connected to the output end of the high-voltage transformer 231; the first electrode 241 and the second electrode 242 are connected to the high-voltage output circuit 233. The voltage of the low-voltage input end is 5 to 12V, and the high-voltage output end is a single-pulse DC voltage, and the pulse peak voltage is between -10KV and +10KV.

[0051] It can be understood that setting the voltage range of the low-voltage input circuit 232 between 5V and 12V ensures the safety of use in the refrigerator. Moreover, the voltage range between 5V and 12V is usually applicable to common power adapters or battery-powered systems, facilitating users to access the mains power or use a portable power supply for power supply.

[0052] Designing the high-voltage output circuit 233 as a single-pulse DC voltage with its pulse peak voltage between -10KV and +10KV, the high-voltage pulse output is the key to generating ionization discharge, which can ensure the formation of a strong enough electric field between the electrodes, and the first electrode 241 and the second electrode 242 form a high-voltage discharge structure.

[0053] Pulse voltage can reach a very high peak value in an extremely short time, thus quickly forming a strong electric field between the electrodes and promoting the ionization of air molecules. When the high-voltage is turned on and the pulse is at its peak, the voltage difference is the largest, causing the air in the reaction area to be rapidly ionized. By the intermittent working mode of the pulse voltage, the continuous discharge phenomenon between the electrodes can be reduced, thereby reducing the wear rate of the electrodes and extending their service life.

[0054] When the power supply provides a negative high voltage to the first electrode 241, a high-intensity electric field will be formed around the first electrode 241. Under the action of the high-intensity electric field, air molecules begin to be ionized, generating high-concentration ozone or high-energy electrons, negative ions, excited-state particles, and highly reactive free radicals with strong oxidizing properties. These highly reactive free radicals can degrade odors and bacteria, causing large odor molecules to be degraded into short-chain small molecules, which belongs to a pre-treatment process for odors.

[0055] During use, the continuous discharge phenomenon between the electrodes can be reduced by the intermittent working mode of the pulse voltage, thereby reducing the wear rate of the electrodes and extending their service life.

[0056] Figure 4 It is a schematic structural diagram of another embodiment of the purification component in the purification component 200 provided by the embodiment of the present utility model.

[0057] Refer to Figure 4 , in some embodiments of the present utility model, the purification component 200 further includes a first heating element 250, and the first heating element 250 is encapsulated at the input end of the high-voltage transformer 231 through insulating glue.

[0058] By providing the first heating element 250, it is used to heat the power supply device 230 so that the power supply device 230 can operate normally in a low-temperature environment, which can improve the reliability of the purification component 200 and ensure that the purification component 200 has a good purification effect.

[0059] Among them, both the first heating element 250 and the second heating element 260 can be structures such as heating wires and heating plates, and can also adopt a structure of a heating wire cooperating with a heat transfer plate. In addition, the first heating element 250 and the second heating element 260 can also include a heating wire and an aluminum foil. The aluminum foil is provided on one side of the heating wire. That is, the heating wire is laid on one surface of the aluminum foil, and the heat transfer area of the heating wire is increased through the aluminum foil to achieve good heat conduction efficiency. In addition, the aluminum foil can also be wrapped on both sides of the heating wire to increase the conduction area of the heating wire.

[0060] Further, the purification component 200 further includes a temperature sensor disposed on the circuit board 220 for monitoring the temperature at the location where the circuit board 220 is located. Thus, the first heating element 250 is controlled to start heating through the temperature information detected by the temperature sensor, so that the power device 230 can ensure to be within the normal operating temperature range, improving the reliability of the purification component 200 and effectively maintaining the purification effect of the purification component 200. Thus, the automatic control of the first heating element 250 is realized.

[0061] It should be noted that both the carrier 213 and the cover 214 provided in the embodiments of the present invention can be made of insulating materials to ensure the electrical isolation of the first electrode 241 and the second electrode 242 from the external environment. For example, both the carrier 213 and the cover 214 are formed of a flame-retardant plastic such as ABS / PP / glass fiber to form an insulating shell to ensure the normal discharge of the first electrode 241 and the second electrode 242.

[0062] It should also be noted that at least one of the first electrode 241 and the second electrode 242 is a titanium alloy electrode or a manganese alloy electrode or a stainless steel electrode.

[0063] Since titanium alloy, manganese alloy and stainless steel are materials with good corrosion resistance. In the application of air purification, the first electrode 241 and the second electrode 242 may come into contact with various chemical substances and humid air. Therefore, using titanium alloy electrodes, manganese alloy electrodes and stainless steel electrodes for the first electrode 241 and the second electrode 242 can significantly improve the durability of the electrodes and reduce the performance degradation or failure caused by corrosion.

[0064] Moreover, titanium alloy electrodes, manganese alloy electrodes and stainless steel electrodes are not only corrosion-resistant, but also have high physical stability and are not easily broken, improving the durability of the purification component. Among them, the stainless steel electrode is made of food-contact grade stainless steel.

[0065] The embodiments of the present invention also provide a refrigeration device, which includes a cabinet body, a door body and the above-mentioned purification component 200. The door body is movably provided on the cabinet body. The purification component 200 is disposed on the cabinet body or the door body, and the opening of the receiving part 2421 of the purification component 200 faces downward.

[0066] When the entire purification component 200 is disposed on the cabinet body or the door body, the purification component 200 has a certain inclination angle to prevent moisture in the air from condensing on one side of the power device 230; at the same time, the opening part of the second electrode 242 faces downward to prevent condensation or icing on the second electrode 242, resulting in the entire electrode being frozen. The original fan in the refrigerator drives the air circulation in the cabinet body to pass through the ionization channel for air purification. The purification component 200 can be provided as an independent module in a low-temperature storage space, such as the freezer compartment of a refrigerator, to purify the air in the freezer compartment.

[0067] When the air in the space where the purification component 200 is located enters the purification component 200 and reaches the positions of the first electrode 241 and the second electrode 242, a current is supplied to the first electrode 241 and the second electrode 242 through the power supply device 230, and ionization discharge can occur between the first electrode 241 and the second electrode 242 to generate a high concentration of ozone, high-energy electrons, negative ions, excited-state particles and strongly oxidizing free radicals between the first electrode 241 and the second electrode 242. The highly active free radicals can degrade odors and bacteria, causing large odor molecules to degrade into short-chain small molecules, which belongs to a process of pre-treating odors.

[0068] In addition, an odor sensor is also provided in the refrigeration device. The odor sensor can be arranged on the inner wall of the door body or the cabinet body to detect the odor concentration in the space, so as to control the operation of the first electrode 241 and the second electrode 242 according to the odor concentration.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
