[0043] In the description of the present invention, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0044] The present application provides a refrigeration device, which can be a device with a low-temperature storage function such as a refrigerator, a freezer, a wine cooler, etc. The following will take an air-cooled refrigerator as an example for detailed description.

[0045] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the refrigeration device according to an embodiment of the present invention. The refrigeration device 10 includes a box body assembly and a purification device 300.

[0046] Among them, the box body assembly includes a box body 100 and a door body 200 movably connected to the box body 100. A storage space 110 is provided in the box body 100, and the door body 200 can move relative to the box body 100 to close or expose the storage space 110.

[0047] The purification device 300 is arranged in the storage space 110, and the purification device 300 is used for sterilizing and purifying the storage space 110. There can be various sterilization methods for the purification device 300. For example, the purification device 300 can adopt ozone sterilization, ultraviolet sterilization, plasma sterilization, etc.

[0048] In the embodiment of the present application, the purification device 300 adopts plasma sterilization technology. For example, the purification device 300 can include an ionization component, and the ionization component discharges electricity to the surrounding air when powered on, and can ionize the surrounding air to excite plasma.

[0049] It can be understood that by discharging electricity to the air to ionize and excite plasma, the plasma contains a large number of charged particles (such as OH−, H3O+, etc.), reactive oxygen species (ROS), reactive nitrogen species (RNS), etc. These active groups such as high-energy electrons and free radicals all have bactericidal effects. They can target and destroy various structures of microorganisms, such as etching cell walls, destroying biofilms and peroxidized lipids, and may cause oxidative damage, base modification and strand breakage of bacterial DNA and RNA, and have a good sterilization and purification effect.

[0050] However, the ionization component to ionize and generate plasma has relatively high requirements for the surrounding environment, especially being greatly affected by the environmental humidity. For example, when the door body 200 is opened to expose the storage space 110, the storage space 110 is communicated with the air environment outside the refrigeration device 10, and the external hot air will enter the storage space 110. The moisture in the hot air will condense when it meets the cold in the storage space 110. If the condensation forms on the ionization component, it will affect the discharge of the ionization component and is not conducive to the generation of plasma. Moreover, the condensation is likely to condense into frost after the cold air blows, which is even less conducive to discharge.

[0051] To solve the above problems, in the embodiments of the present application, the purification device 300 is configured as follows: in the first power-on mode, the door body 200 closes the storage space 110, and the purification device 300 is in the ionization working state; in the second power-on mode, the door body 200 exposes the storage space 110, and the purification device 300 is in the anti-condensation working state.

[0052] Specifically, the purification device 300 may be provided with an anti-condensation mechanism. For example, the purification device 300 may include a heating element that generates heat to increase the temperature of the purification device 300 and reduce the risk of condensation on the purification device 300.

[0053] In this way, the refrigeration device 10 is provided with the purification device 300. In the first power-on mode, the door body 200 closes the storage space 110. At this time, the purification device 300 is in the ionization working state, and plasma can be excited in the storage space 110 to achieve sterilization and purification of the storage space 110. In the second power-on mode, the door body 200 is in the state of exposing the storage space 110, and the purification device 300 is in the anti-condensation working state, which can reduce the condensation on the purification device 300 and minimize the impact of condensation on the ionization operation, thereby improving the reliability of the ionization of the purification device 300, ensuring the sterilization and purification effect of the purification device 300, and improving the safety of the storage environment inside the refrigeration device 10.

[0054] It should be noted that when the door body 200 closes the storage space 110, the purification device 300 may be configured to always work in the ionization state in the first power-on mode, that is, the purification device 300 continuously ionizes plasma in the storage space 110; alternatively, the purification device 300 may be configured to start the first power-on mode intermittently, that is, the purification device 300 is powered on for a period of time to ionize plasma and powered off for a period of time to stop generating plasma.

[0055] In one embodiment, the ionization component 310 is disposed within the air duct member of the air-cooled refrigerator, and a blower is provided within the air duct member. The first power-on mode of the purification device 300 can be associated with the operation of the blower, causing the purification device 300 to start the first power-on mode intermittently. Specifically, in a state where the door body 200 closes the storage space 110, when the blower operates to blow cold air into the storage space 110, the purification device 300 starts the first power-on mode, ionizing plasma within the air supply duct. The plasma follows the supply air flow and flows to various parts of the storage space 110. At the same time, a portion of the plasma can also follow the return air flow and flow into the evaporator chamber through the return air duct, achieving sterilization and disinfection of the entire storage space 110, especially killing bacteria and viruses hidden in areas that are inaccessible to users for cleaning. That is to say, the ionization operation of the purification device 300 runs synchronously with the blower. When the blower operates, the purification device 300 synchronously starts the first power-on mode, enabling the ionized plasma to flow to various positions of the storage space 110 along with the cold air, thereby achieving the best sterilization effect of the purification device 300. When the blower stops operating, the purification device 300 ends the first power-on mode and stops the ionization operation, reducing power consumption.

[0056] In one embodiment, the refrigeration device 10 further includes a triggering device configured to: when the door body 200 exposes the storage space 110, trigger the purification device 300 to start the second power-on mode; when the door body 200 moves from the state of exposing the storage space 110 to closing the storage space 110, trigger the purification device 300 to end the second power-on mode.

[0057] There can be various triggering methods for the triggering device. The triggering device can be a mechanical triggering mechanism. For example, a switch for starting or ending the second power-on mode can be provided on the purification device 300. The mechanical triggering mechanism is connected to the door body 200, and when the door body 200 moves, it can drive the mechanical triggering mechanism to move together, causing the mechanical triggering mechanism to press the switch to mechanically trigger the purification device 300, thereby achieving starting or ending the second power-on mode. The triggering device can also be an electrical trigger implemented by combining a sensor and an electronic control board.

[0058] To simplify the overall structure of the refrigeration device 10, in one embodiment, please refer to Figure 2 , Figure 2 which is the electrical structure block diagram of the refrigeration device according to the embodiment of the present invention. The triggering device 400 includes a detector 410 and a controller 420. The detector 410 is configured to detect the opening and closing state of the door body and output an electrical signal. The controller 420 is electrically connected to the detector 410 and the purification device 300, and the controller 420 is configured to control the purification device 300 to start or end the second power-on mode according to the electrical signal output by the detector 410.

[0059] Specifically, the door body 200 is initially in a closed state, that is, in a state of enclosing the storage space 110. When the door body 200 is opened to expose the storage space 110, the detector 410 detects that the door body 200 is in an open state. At this time, the detector 410 outputs a first electrical signal to the controller 420. After receiving the first electrical signal, the controller 420 sends a first control signal to the purification device 300 to control the purification device 300 to start the second power-on mode, so that the purification device 300 performs the dew condensation removal operation. When the door body 200 is switched from the open state to the closed state again, the detector 410 detects this change and outputs a second electrical signal to the controller 420. After receiving the second electrical signal, the controller 420 sends a second control signal to the purification device 300 to control the purification device 300 to end the second power-on mode and stop the dew condensation removal operation.

[0060] Among them, there are various detection methods for the detector 410. For example, the detector 410 can be a photoelectric sensor. When the door body 200 is opened and closed, there will be a change in the light intensity in the storage space 110. By detecting the change in the light intensity in the storage space 110, the opening and closing state of the door body 200 can be judged; the detector 410 can also be a microswitch. When the door body 200 is closed, it pushes the contact of the microswitch to close and triggers the circuit. When the door body 200 is opened away from the microswitch, its contact is disconnected and the circuit is interrupted. By detecting the change in the circuit, the opening and closing state of the door body 200 can also be judged. The detection method adopted by the detector 410 can be determined according to the specific production requirements of the refrigeration device 10, and the present application does not limit this.

[0061] For a general refrigerator, the refrigerator itself is provided with a detection device to judge the opening and closing state of the refrigerator door, so as to control some functional operations of the refrigerator. For example, when the detection device detects that the refrigerator door is opened, the lighting element inside the refrigerator emits light for illumination; when the detection device detects that the refrigerator door is closed, the lighting element inside the refrigerator goes out and stops illumination. The detector 410 in this embodiment can be improved by using this detection device, so that the detection device is not only associated with the lighting control in the refrigeration device 10, but also associated with the control of the purification device 300. In this way, multiple functional operations of the refrigeration device 10 share the same detector 410, without increasing the number of detectors 410, and the cost can be reduced.

[0062] Please refer to Figure 3 , Figure 3Schematic block diagram of a purification device according to an embodiment of the present invention. The refrigeration device 10 includes an electronic control module 330 and an ionization assembly 310. The electronic control module 330 is electrically connected to the ionization assembly 310 to supply power to the ionization assembly 310. The electronic control module 330 is provided with a control circuit, and there are many electronic components on the control circuit. Since it is not easy for electronic components to start at low temperatures and there is attenuation when they are in a low-temperature environment for a long time, in order to avoid affecting the life and reliability of the electronic control module 330, the electronic control module 330 and the ionization assembly 310 can be separated, the electronic control module 330 can be far away from the ionization assembly 310, and is arranged in a region with a relatively higher temperature in the refrigeration device 10.

[0063] In one embodiment, the storage space 110 includes a first storage space 111 and a second storage space 112. The refrigeration temperature of the first storage space 111 is lower than that of the second storage space 112. The ionization assembly 310 is arranged in the first storage space 111, and the electronic control module 330 is arranged in the second storage space 112. The ionization assembly 310 and the electronic control module 330 are connected by a cable.

[0064] Among them, the storage space 110 can be used as the freezer compartment of the refrigeration device 10, and the second storage space 112 can be used as the refrigerated compartment of the refrigeration device 10. That is to say, the ionization assembly 310 is arranged in the freezer compartment, and the electronic control module 330 is arranged in the refrigerated compartment.

[0065] The electronic control module 330 can include an input circuit, a boost circuit, and an output circuit. Among them, the input circuit is used to connect to an external power supply through an input interface, and the external power supply can be the control power supply in the refrigeration device 10. The output circuit is electrically connected to the ionization assembly 310 through an output interface. The input circuit is coupled to the output circuit through the boost circuit. The boost circuit is used to controllably convert the low-voltage power input by the input circuit into the high-voltage power required for ionization of the ionization assembly 310 and output it through the output circuit. For example, the voltage input from the input circuit is the third voltage, and the boost circuit is used to boost the third voltage to the fourth voltage. The fourth voltage meets the ionization requirements of the ionization assembly 310, and the fourth voltage is greater than the third voltage. The boost circuit can include a transformer, and the circuit structure of the transformer is well known to those skilled in the art and will not be elaborated in the description of this embodiment.

[0066] Please refer to Figure 4 , Figure 4Schematic block diagram of a purification device according to another embodiment of the present utility model. The purification device 300 includes an ionization component 310 and a heating element 320. Among them, the ionization component 310 is the core functional component of the purification device 300. The purification device 300 discharges the air in the storage space 110 through the ionization component 310 to realize the excitation and ionization of plasma in the storage space 110. The heating element 320 is used to radiate energy to the ionization component 310 in the energized state to increase the temperature of the ionization component 310, thereby reducing the condensation of moisture on the ionization component 310.

[0067] Specifically, when the purification device 300 is in the first power-on mode, the purification device 300 supplies power to the ionization component 310; when the purification device 300 is in the second power-on mode, the purification device 300 supplies power to the heating element 320.

[0068] Among them, the way in which the heating element 320 radiates energy to the ionization component 310 to increase the temperature of the ionization component 310 can be that the heating element 320 itself can generate heat and radiate the generated heat to the ionization component 310 through air or other media, or it is in contact with the ionization component 310 to directly transfer the heat to the ionization component 310, that is, the temperature of the ionization component 310 is increased by means of heat exchange; it can also be that the heating element 320 itself does not generate heat (or generates very little heat), and the energy radiated by the heating element 320 can be absorbed by the ionization component 310 and converted into heat energy. For example, the heating element 320 can be configured as an infrared light source, and the infrared light source radiates infrared rays (electromagnetic waves) to the ionization component 310, and the ionization component 310 absorbs the infrared rays and converts them into heat, thereby increasing the temperature of the ionization component 310.

[0069] In one embodiment, the heating element 320 is configured to generate heat in the energized state. Among them, the heating element 320 can be one of a resistor, an inductor, and a capacitor. Specifically, when the door body 200 exposes the storage space 110, the purification device 300 starts the second power-on mode. At this time, the heating element 320 is energized to generate heat, and the heat is transferred to the ionization component 310. The ionization component 310 absorbs the heat and heats up, so that the temperature of the ionization component 310 is higher than the temperature of other structural components in the storage space 110. Therefore, the moisture entering the storage space 110 is more likely to condense on other structural components, which can effectively reduce the condensation on the ionization component 310 and reduce the influence of condensation on the ionization of the ionization component 310. In one embodiment, the heating element 320 is a resistor.

[0070] It can be understood that the heating element 320 can be arranged close to the ionization component 310 so that the heat generated by the heating element 320 can be quickly transferred to the ionization component 310, the temperature of the ionization component 310 can be quickly increased, and the ionization component 310 can receive enough heat, so that the ionization component 310 can be heated to a large temperature difference from other surrounding structural components to reduce condensation.

[0071] In order to better transfer the heat generated by the heating element 320 to the ionization assembly 310, in one embodiment, the heating element 320 and the ionization assembly 310 are set as an integrated structure. That is to say, the heating element 320 and the ionization assembly 310 are integrated into one, so that the heat generated by the heating element 320 can be transferred to the ionization assembly 310 more quickly, so that the ionization assembly 310 is quickly heated to a higher temperature, while reducing the loss in the heat transfer process, and improving the heat utilization rate of the heating element 320. Moreover, the heat generated by the heating element 320 is more transferred to the ionization assembly 310, reducing the heat transferred to other areas of the storage space 110, which can reduce the impact on the temperature in the storage space 110.

[0072] In addition, the heating element 320 and the ionization assembly 310 are set as an integrated structure. The heating element 320 and the ionization assembly 310 are a whole, which reduces the number of parts of the purification device 300. The two do not need to be installed separately, which facilitates the assembly of the purification device 300.

[0073] Please refer to Figure 5 and Figure 6 , Figure 5 This is a first assembly diagram of the ionization component and the heating element of the first embodiment of the utility model. Figure 6 The second assembly diagram of the ionization assembly and the heating element of the first embodiment of the utility model. In one embodiment, the refrigeration device 10 includes a mounting portion 340, and the ionization assembly 310 and the heating element 320 are arranged on the mounting portion 340. The mounting portion 340 serves as a support carrier for the ionization assembly 310 and the heating element 320, so that the ionization assembly 310 and the heating element 320 are firmly connected to form an integrated structure; at the same time, the mounting portion 340 also serves as an installation function, so as to install the ionization assembly 310 and the heating element 320 into the storage space 110.

[0074] Since the ionization component 310 generally requires a higher power supply voltage for ionization, and the heating element 320 is usually a low-voltage component, in order to avoid the heating element 320 from being broken down, the mounting part is made of insulating material to prevent the high voltage electricity on the ionization component 310 from flowing to the heating element 320 through the mounting part 340, thereby protecting the heating element 320; at the same time, the mounting part 340 insulates and isolates the ionization component 310 from other structural parts in the storage space 110 to prevent electric shock accidents.

[0075] The ionization assembly 310 includes an ionization head 311, which is used to discharge the surrounding air to ionize the air and generate plasma. It can be understood that although the heating element 320 and the ionization assembly 310 are set as an integrated structure, a certain distance is still required between the heating element 320 and the ionization head 311 to prevent the high voltage on the ionization head 311 from damaging the heating element 320. Please refer toFigure 5 , the ionization assembly 310 includes an insulating member 312 disposed between the ionization head 311 and the heating member 320 to separate the ionization head 311 and the heating member 320.

[0076] In one embodiment, as Figure 5 shown, the ionization head 311 includes a first ionization head (not labeled) and a second ionization head (not labeled), the heating member 320 is disposed between the first ionization head and the second ionization head, and the heat generated by the heating member 320 can be evenly transferred to the two ionization heads 311. Correspondingly, the insulating member 312 includes a first insulating member (not labeled) and a second insulating member (not labeled), the first insulating member is disposed between the first ionization head and the heating member 320, and the second insulating member is disposed between the second ionization head and the heating member 320. Among them, the ionization head 311 adopts a needle-shaped electrode, which is beneficial to discharge, and the insulating member 312 is designed in a ring shape along the circumferential direction of the ionization head 311.

[0077] In one embodiment, referring to Figure 5 and Figure 6 shown, the mounting portion 340 includes an outer frame 341 and a sealing member 342. The ionization head 311 and the heating member 320 are disposed inside the outer frame 341. The ionization head 311 includes a base portion 3111 and an ionization portion 3112 connected to the base portion 3111, and the sealing member 342 covers the heating member 320 and the base portion 3111, only exposing the ionization portion 3112 for discharging.

[0078] By providing the sealing member 342 to cover the heating member 320 and the base portion 3111, the heating member 320 and the base portion 3111 of the ionization head 311 are isolated from the air environment in the storage space 110, avoiding direct contact between cold air or moisture and the heating member 320 and the base portion 3111, and preventing corrosion and damage of the heating member 320 and the base portion 3111.

[0079] It can be understood that the sealing member 342 is made of an insulating material, so that the sealing member 342 has electrical insulation, preventing the high-voltage electricity on the ionization head 311 from being transmitted to the heating member 320 through the sealing member 342 and avoiding damage to the heating member 320. At the same time, the sealing member 342 is also made of a heat-conducting material, so that the sealing member 342 has a heat-conducting function, and the heat generated by the heating member 320 can be quickly transferred to the ionization head 311 through the sealing member 342, causing the temperature of the ionization head 311 to rise rapidly.

[0080] In one embodiment, the seal 342 is formed by solidifying a sealing liquid filled in the outer frame 341, where the sealing liquid can be epoxy resin, polyurethane, etc. By filling the sealing liquid to form the above-mentioned seal 342, there is no need for complex processing for the sealing assembly of the seal 342 with the ionization head 311 and the heating element 320, which is convenient for production. Moreover, the liquid medium has good fluidity and can flow into the tiny gap between the ionization head 311 and the heating element 320, so that the solidified seal 342 firmly connects the ionization head 311 and the heating element 320 together, improving the reliability.

[0081] The above first embodiment provides a method of setting the heating element 320 to radiate energy to the ionization assembly 310 to increase the temperature of the ionization assembly 310 to avoid condensation. In addition, in some embodiments, it can also be to set the structure of the ionization assembly 310 itself so that the ionization assembly 310 can generate heat by itself to increase its temperature.

[0082] In one embodiment, please refer to Figure 7 , Figure 7 which is a schematic structural diagram of the ionization assembly of the second embodiment of the present invention. Different from the purification device 300 of the above first embodiment, the purification device 300 in this embodiment omits the heating element 320. The purification device 300 includes an ionization assembly 310, and the ionization assembly 310 includes a first electrode 313, a second electrode 314, and an insulating medium 315 disposed between the first electrode 313 and the second electrode 314.

[0083] Among them, the first electrode 313, the second electrode 314, and the insulating medium 315 form a capacitor. After a power supply is applied between the first electrode 313 and the second electrode 314, discharge occurs based on the potential difference between the first electrode 313 and the second electrode 314, and the air around the first electrode 313 or the second electrode 314 can be excited to ionize plasma. It should be noted that for the ionization assembly 310 adopting the structure of this embodiment, an alternating current needs to be configured to supply power to the ionization assembly 310.

[0084] Due to the presence of the insulating medium 315, heat will be generated during the discharge process of the ionization assembly 310, causing its own temperature to rise. Then, when the door body 200 exposes the storage space 110, the heat generated by the discharge of the ionization assembly 310 can be utilized to make the temperature of the ionization assembly 310 higher than that of other structural parts of the storage space 110, reducing the condensation of moisture on the ionization assembly 310. That is to say, when the door body 200 exposes the storage space 110, the ionization assembly 310 is in an energized state.

[0085] In this embodiment, when the purification device 300 is in the first power-on mode, a first voltage is applied between the first electrode 313 and the second electrode 314 to cause the first electrode 313 and the second electrode 314 to discharge and ionize to generate plasma; when the purification device 300 is in the second power-on mode, a second voltage is applied between the first electrode 313 and the second electrode 314 to cause the first electrode 313 and the second electrode 314 to heat up, so as to increase the temperature of the ionization assembly 310; wherein, the second voltage is less than the first voltage.

[0086] It can be understood that when the door body 200 reveals the storage space 110, generally the user opens the door body 200 to take and place items in the storage space 110. In this embodiment, the second voltage is set to be less than the first voltage, that is, a lower voltage is applied between the first electrode 313 and the second electrode 314, which is sufficient for the two to heat up to increase their own temperature, but not sufficient to generate plasma, so it will not affect the physical health of the user, and at this time the power supply voltage is low, avoiding electric shock accidents.

[0087] Since a relatively large amount of heat is generated during the process of the ionization assembly 310 discharging to ionize plasma, in order to avoid the heat generated by the ionization assembly 310 having a greater impact on the temperature in the storage space 110, in some embodiments, when the door body 200 closes the storage space 110, the purification device 300 is configured to intermittently start the first power-on mode.

[0088] For the ionization assembly 310 to better ionize plasma, as Figure 7 shown, the first electrode 313 and the second electrode 314 are arranged in a plate shape, and the distance between the first electrode 313 and the second electrode 314 is constant, so as to generate a stable discharge state between the first electrode 313 and the second electrode 314, thereby better ionizing plasma.

[0089] One of the first electrode 313 and the second electrode 314 is arranged inside the insulating medium 315, and the other of the first electrode 313 and the second electrode 314 is exposed on the surface of the insulating medium 315. Taking the first electrode 313 being arranged inside the insulating medium 315 as an example, the first electrode 313 is completely covered by the insulating medium 315, and the first electrode 313 is isolated from the air environment in the storage space 110, so that the moisture entering the storage space 110 only affects the second electrode 314, making it easier to reduce the condensation on the ionization assembly 310 and improve the ionization reliability of the ionization assembly 310.

[0090] The above has described the embodiments of the present invention in detail with reference to the drawings, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
