[0038] Refrigeration equipment such as refrigerators provides a low-temperature storage environment, which can extend the storage duration of stored items such as food and medicine. However, some bacteria can still survive and reproduce in a relatively low-temperature environment, posing a threat to the food in the refrigeration equipment, and the food is easily contaminated with bacteria and deteriorates more quickly. Especially for air-cooled refrigerators, since bacteria may reproduce in locations such as the air duct that users cannot see and are difficult to clean, and the air supply airflow can carry the bacteria in these parts and spread the bacteria to various parts of the refrigeration equipment, seriously affecting the safety of the storage environment of the refrigeration equipment.

[0039] To this end, the present application provides a purification device and a refrigeration device using the purification device. Specifically, the purification device is used to sterilize and purify the storage environment inside the refrigeration device, improving the safety of the storage environment of the refrigeration device. Among them, the refrigeration device can be a device with a low-temperature storage function such as a refrigerator, a freezer, a wine cooler, etc. The following will mainly take the purification device applied to a refrigerator as an example for detailed description.

[0040] 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 100. The box body 100 is provided with a storage space 110, and the purification device is disposed in the storage space 110.

[0041] Please refer to Figure 2 , Figure 2 which is a schematic block diagram of the purification device according to an embodiment of the present invention. In the embodiment of the present application, the purification device 300 includes a purification component 310. The purification component 310 is the main functional component of the purification device 300, and the purification component 310 is configured to perform a sterilization operation on the storage space 110 in the energized state. Among them, the purification component 310 can adopt sterilization methods such as ozone sterilization, plasma sterilization, ultraviolet sterilization, etc. to eliminate bacteria, viruses, etc. in the storage space 110, realizing the sterilization and purification of the storage space 110.

[0042] In an embodiment of the present application, the purification device 300 adopts plasma sterilization. The purification component 310 includes an ionization part, and the ionization part is configured to be able to excite and ionize the surrounding air into plasma in the energized state.

[0043] It can be understood that by ionizing the air through the ionization part to 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 high-energy electrons and free radicals and other active groups 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, having a good sterilization and purification effect.

[0044] The ionization part usually needs to ionize the air to excite plasma under a relatively high voltage. To meet the power supply requirements of the ionization part, please continue to refer to Figure 2 , the purification device 300 includes an electronic control module 320. The electronic control module 320 is electrically connected to the purification component 310, and the electronic control module 320 is used to supply power to the purification component 310. It can be understood that the electronic control module 320 is also electrically connected to an external power supply, and the electronic control module 320 can convert the supply voltage input by the external power supply into the working voltage required for the purification component 310 to achieve ionization.

[0045] However, the temperature in the storage space 110 is relatively low. Especially for the freezing compartment, the temperature in the freezing compartment is generally dozens of degrees below zero. When the purification device 300 is arranged in the freezing compartment, it is difficult for the electronic control module 320 to start in a low-temperature environment, and the electronic components in the electronic control module 320 are prone to attenuation when working in a low-temperature environment for a long time, which affects the reliability of the power supply of the electronic control module 320 and the service life of the electronic control module 320.

[0046] To solve the above problems, the purification device 300 according to the embodiment of the present application further includes a heating module 330, and the heating module 330 is used to radiate energy to the electronic control module 320 to increase the temperature of the electronic control module 320.

[0047] Then, in the embodiment of the present utility model, by arranging the heating module 330 to radiate energy to the electronic control module 320 to increase the temperature of the electronic control module 320, the temperature of the electronic control module 320 can be higher than the air temperature in the storage space 110, reducing the impact of the low-temperature storage environment on the electronic components in the electronic control module 320, enabling the electronic control module 320 to work normally, improving the reliability and service life of the electronic control module 320, and further ensuring the reliability of the purification device 300 and improving the safety of the storage environment in the refrigeration device 10.

[0048] Moreover, by means of the heating module 330, the impact of the low-temperature environment on the electronic control module 320 is reduced, enabling the electronic control module 320 to be arranged at a lower-temperature part in the refrigeration device 10. For example, the electronic control module 320 can be arranged in the freezer or the freezing air duct, eliminating the harsh condition that the electronic control module 320 needs to be installed far away from the low-temperature area. The electronic control module 320 can be arranged in the same area of the storage space 110 following the purification component 310, which is convenient for the assembly of the electronic control module 320 and can simplify the overall structure of the purification device 300. For example, when the purification component 310 is arranged in the freezing air duct, the electronic control module 320 can also be arranged in the freezing air duct, effectively shortening the length of the connecting cable between the two.

[0049] Among them, the way that the heating module 330 radiates energy to the electronic control module 320 to increase the temperature of the electronic control module 320 can be that the heating module 330 itself can generate heat and radiate the generated heat to the electronic control module 320 through air or other media, or be in contact with the electronic control module 320 to directly transfer the heat to the electronic control module 320 to increase the temperature of the electronic control module 320; it can also be that the heating module 330 itself does not generate heat (or generates very little heat), and the energy radiated by the heating module 330 can be absorbed by the electronic control module 320 and converted into heat energy. For example, the heating module 330 can be configured as an infrared light source, and the infrared light source radiates infrared rays (electromagnetic waves) to the electronic control module 320, and the electronic control module 320 absorbs the infrared rays and converts them into heat, thereby increasing the temperature of the electronic control module 320.

[0050] To rapidly increase the temperature of the electronic control module 320, the heating module 330 is configured to generate heat when powered on. Among them, the heating module 330 can be one of a resistor, an inductor, and a capacitor. In one embodiment, the heating module 330 is a resistor.

[0051] In one embodiment, the heating module 330 and the electronic control module 320 are provided as an integrated structure. That is to say, the heating module 330 and the electronic control module 320 are integrated into one body, so that the heat generated by the heating module 330 is directly and rapidly transferred to the electronic control module 320, enabling the electronic control module 320 to reach the working temperature faster, while reducing heat loss and improving the thermal utilization rate of the heating module 330; moreover, the heating module 330 and the electronic control module 320 are a whole, reducing the number of components of the purification device 300, making the overall design of the purification device 300 more compact and facilitating the assembly of the purification device 300.

[0052] In one embodiment, the electronic control module 320 may include a circuit board, and a circuit structure for controlling the operation of the purification component 310 is provided on the circuit board. The heating module 330 is a resistor 331, and the resistor 331 can be connected to the circuit board.

[0053] Among them, the heating module 330 can operate intermittently, that is, the heating module 330 radiates energy to the electronic control module 320 for a period of time and stops radiating for a period of time.

[0054] In one embodiment, the heating module 330 is configured to: when the temperature of the electronic control module 320 is lower than the preset temperature, the heating module 330 radiates energy to the electronic control module 320; when the temperature of the electronic control module 320 is at the preset temperature, the heating module 330 stops radiating.

[0055] Among them, the preset temperature is a reference temperature set in advance in the control program of the refrigeration device 10 to determine whether to control the operation of the heating module 330. It can be understood that the preset temperature can be a specific temperature value or a temperature range. To better control the operation of the heating module 330, in one embodiment, the preset temperature is in the range of -30°C to -25°C.

[0056] Specifically, when the temperature of the electronic control module 320 is lower than -30°C, the heating module 330 radiates energy to the electronic control module 320 to increase the temperature of the electronic control module 320. When the temperature of the electronic control module 320 is between -30°C and -25°C, the heating module 330 stops radiating. In this way, through the intermittent operation of the heating module 330, the power consumption of the heating module 330 can be reduced, thereby reducing the overall power consumption of the refrigeration device 10. Moreover, it is avoided that the heating module 330 works for a long time and radiates heat to other areas of the storage space 110, reducing the impact of the heating module 330 on the temperature inside the storage space 110.

[0057] Of course, in other alternative embodiments of the present application, the heating module 330 can also be configured to always work, that is, the heating module 330 always radiates energy to the electronic control module 320 so that the temperature of the electronic control module 320 can always be maintained at the above preset temperature. For example, when the storage temperature in the storage space 110 is extremely low, the intermittent operation of the heating module 330 cannot meet the temperature requirements of the electronic control module 320, and the heating module 330 can be controlled to always work. It should be noted that here it means that the heating module 330 always works on the premise that the refrigeration device 10 is powered on.

[0058] Please refer to Figure 3 , Figure 3 which is the electrical structure block diagram of the refrigeration device according to the embodiment of the present utility model. The purification device 300 includes a first detector 400. The first detector 400 is used to detect the temperature of the electronic control module 320. The heating module 330 is configured to radiate energy to the electronic control module 320 when the first detector 400 detects that the temperature of the electronic control module 320 is lower than the preset temperature until the temperature of the electronic control module 320 rises to the preset temperature and then stops. Among them, the first detector 400 is a temperature sensor, and the first detector 400 can be arranged inside the electronic control module 320 to avoid the interference of the air temperature inside the storage space 110.

[0059] Specifically, when the first detector 400 detects that the temperature of the electronic control module 320 is lower than the preset temperature, at this time the first detector 400 outputs a first electrical signal. The controller 600 of the refrigeration device 10 receives the first electrical signal and controls the heating module 330 to radiate energy to increase the temperature of the electronic control module 320. When the first detector 400 detects that the temperature of the electronic control module 320 is at the preset temperature, the first detector 400 outputs a second electrical signal. The controller 600 receives the second electrical signal and controls the heating module 330 to stop radiating. In this way, by setting the first detector 400, the refrigeration device 10 controls the operation of the heating module 330 according to the temperature data detected by the first detector 400, realizing the automatic control of the heating module 330.

[0060] Such as Figure 1As shown in the figure, the refrigeration device 10 further includes a door body 200. The door body 200 is movably connected to 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. When the door body 200 exposes the storage space 110, the storage space 110 communicates with the external environment of the refrigeration device 10, and the hot air in the external environment 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 moisture condenses on the electronic control module 320, first, it is easy to freeze after being blown by the cold air, making the electronic control module 320 at a relatively low temperature, affecting the startup of the electronic control module 320. Second, it is easy to corrode and damage the electronic components in the circuit control, affecting the reliability of the electronic control module 320.

[0061] In this regard, in one embodiment, the heating module 330 is further configured to: when the door body 200 exposes the storage space 110, the heating module 330 radiates energy to the electronic control module 320; when the door body 200 moves from exposing the storage space 110 to closing the storage space 110, the heating module 330 stops radiating energy.

[0062] In this embodiment, the control of the heating module 330 is associated with the opening and closing state of the door body 200. When the door body 200 is opened to expose the storage space 110, the heating module 330 is controlled to radiate energy to the electronic control module 320, so that the temperature of the electronic control module 320 rises, and the temperature of the electronic control module 320 is higher than the temperature of other structural components in the storage space 110. Then, the moisture entering the storage space 110 is not easy to condense on the electronic control module 320, but is more likely to condense when meeting the cold at other parts of the storage space 110, thereby reducing the condensation on the electronic control module 320, reducing the impact on the electronic control module 320, and improving the reliability of the electronic control module 320. When the door body 200 is switched from the open state to the closed state to close the storage space 110, the heating module 330 is controlled to stop radiating. Since the opening and closing time of the door body 200 of the refrigeration device 10 is generally short, the energy radiated by the heating module 330 has little impact on the temperature in the storage space 110, and hardly affects the refrigeration or freezing effect of the food in the storage space 110.

[0063] It can be understood that the external environmental temperature is often much higher than the temperature in the storage space 110. To effectively improve the condensation situation on the electronic control module 320, when the door body 200 exposes the storage space 110, the heating module 330 is controlled to radiate energy at a relatively high power, so that the electronic control module 320 can be heated to a relatively high temperature (higher than the above preset temperature), reducing the temperature difference with the external environment of the refrigeration device 10. For example, when the heating module 330 is a resistor 331, controlling the resistor 331 to generate heat to raise the temperature of the electronic control module 320 above 0°C can effectively reduce the condensation of moisture on the electronic control module 320.

[0064] In one embodiment, please refer to againFigure 3 The purification device 300 further includes a second detector 500 for detecting the opening and closing state of the door body 200, so that the refrigeration device 10 controls whether the heating module 330 operates according to the opening and closing state of the door body 200.

[0065] 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 second detector 500 detects that the door body 200 is in an open state. At this time, the second detector 500 outputs a third electrical signal to the controller 600, and the controller 600 controls the heating module 330 to radiate energy according to the third electrical signal, so that the temperature of the electronic control module 320 increases. When the door body 200 is switched from the open state to the closed state again, the second detector 500 outputs a fourth electrical signal to the controller 600, and the controller 600 controls the heating module 330 to stop radiating according to the fourth electrical signal. Then, by setting the second detector 500 to detect the opening and closing state of the door body 200, automatic control of the heating module 330 is achieved.

[0066] There are various detection methods for the second detector 500. For example, the second detector 500 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 second detector 500 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 second detector 500 can be determined according to the specific production requirements of the refrigeration device 10, and the present application does not limit this.

[0067] For a general refrigerator, the refrigerator itself is provided with a detection device for judging the opening and closing state of the refrigerator door to control some functional operations of the refrigerator. For example, when the detection device detects that the refrigerator door is opened, the light-emitting part inside the refrigerator emits light for illumination; when the detection device detects that the door body 200 is closed, the light-emitting part in the refrigerator goes out and stops illuminating. The second detector 500 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 heating module 330. In this way, multiple functional operations of the refrigeration device 10 share the same detector, and there is no need to increase the number of detectors, which can reduce costs.

[0068] Please refer to Figure 4 , Figure 4This is a circuit schematic diagram of the electric control module and the heating module of the purification device according to the embodiment of the present utility model. The electric control module 320 includes an input circuit 321, a boost circuit 322, and an output circuit 323. The input circuit 321 is coupled to the output circuit 323 through the boost circuit 322. The output circuit 323 is electrically connected to the purification component 310. The boost circuit 322 is used to boost the supply voltage input by the input circuit 321 to the working voltage required for the ionization of the purification component 310.

[0069] Among them, the input circuit 321 is used to connect to an external power supply through the input interface 3211. The external power supply can be the control power supply of the refrigeration device 10, such as Figure 4 As shown, two input interfaces 3211 are provided at one end of the input circuit 321. The two input interfaces 3211 are respectively connected to the positive and negative electrodes of the external power supply. When the input circuit 321 is connected to the external power supply through the input interface 3211, the boost circuit 322 starts to work.

[0070] The boost circuit 322 is used to controllably convert low-voltage electricity into high-voltage electricity required by the purification component 310. For example, the voltage input from the input circuit 321 is the first voltage, and the boost circuit 322 is used to boost the first voltage to the second voltage. The second voltage meets the excitation ionization requirements of the purification component 310, and the second voltage is greater than the first voltage. The boost circuit 322 may 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.

[0071] The output circuit 323 is used to output high-voltage electricity, such as Figure 4 As shown, an output interface 3231 is provided at one end of the output circuit 323. The output circuit 323 is used to be electrically connected to the ionization part of the purification component 310 through the output interface 3231.

[0072] In one embodiment, the heating module 330 is disposed between the input circuit 321 and the boost circuit 322.

[0073] When the heating module 330 uses the resistor 331 to generate heat, the resistor 331 is a low-voltage component. Placing the low-voltage component close to the high voltage is likely to break down the low-voltage component. In this embodiment, the resistor 331 is arranged between the input circuit 321 and the boost circuit 322, so that the resistor 331 is far away from the output circuit 323, that is, far away from the high-voltage part, making it easier to protect the resistor 331 and avoid the high voltage of the output circuit 323 from affecting the resistor 331. At the same time, the resistor 331 is arranged between the input circuit 321 and the boost circuit 322, so that the resistor 331 is close to the middle position of the electronic control module 320, making the resistor 331 have a more appropriate distance from the input circuit 321 and the boost circuit 322, and not being too far away from the output circuit 323, so that the heat generated by the resistor 331 can be transferred to the input circuit 321, the boost circuit 322, and the output circuit 323, so that the temperatures of the input circuit 321, the boost circuit 322, and the output circuit 323 can all increase.

[0074] Please continue to refer to Figure 4 , the input circuit 321 includes a first input line 3212 and a second input line 3213. One end of the input circuit 321 is connected to the positive pole of the external power supply through the first input line 3212, and the other end of the input circuit 321 is connected to the negative pole of the external power supply through the second input line 3213. The electronic control module 320 further includes a third input line 3214. One end of the heating module 330 is connected to the positive pole of the external power supply through the third input line 3214, and one end of the heating module 330 is connected to the above-mentioned second input line 3213 to be connected to the negative pole of the external power supply through the second input line 3213.

[0075] Then, when the heating module 330 is the resistor 331, the input circuit 321 and the resistor 331 share the second input line 3213, so that the heat generated when the resistor 331 is energized can be transferred through the second input line 3213, further improving the temperature increase effect on the electronic control module 320.

[0076] In one embodiment, the purification device 300 further includes a seal, and the seal covers the heating module 330, the boost circuit 322, a part of the input circuit 321, and a part of the output circuit 323, only exposing the input interface 3211 and the output interface 3231.

[0077] The seal covers the heating module 330, the boost circuit 322, a part of the input circuit 321, and a part of the output circuit 323, isolating the above circuit structure from the air environment in the storage space 110, avoiding direct contact between cold air or moisture and the above circuit structure, and further improving the reliability of the electronic control module 320.

[0078] It is understandable that the seal is made of an insulating material to endow the seal with insulation, so as to avoid the influence of the high voltage of the output circuit 323 on the heating module 330 (resistor 331). At the same time, the seal is also made of a heat-conducting material to endow the seal cover with heat conduction, so that the heat generated by the heating module 330 can be quickly transferred to all parts of the electronic control module 320 through the seal, making the temperature of all parts of the electronic control module 320 uniform.

[0079] In one embodiment, the seal is formed by solidifying a sealing liquid sprayed on the above circuit structure, wherein the sealing liquid can be epoxy resin, polyurethane, etc.

[0080] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.
