Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to catalyst components and their control methods, control devices, and refrigerators. Background Technology

[0002] Currently, users are increasingly concerned about the hygiene of household appliances. Taking refrigerators as an example, the freezer and ice maker compartments typically share a large freezer space and air duct. The freezer compartment usually contains foods with strong odors, such as seafood and meat, while the ice maker is used to store ice. Because the freezer and ice maker share an air duct, it's easy for odors to cross between the ice. Simultaneously, if the refrigerator, freezer, and ice maker compartments also share an air duct, odor molecules from foods with strong odors, such as durian, onions, kimchi, and leftovers, placed in the refrigerator compartment can enter the freezer and then the ice maker, causing unpleasant odors in the ice and promoting bacterial growth. Commonly used technologies include antibacterial agents, activated carbon, low-temperature catalysts, and photocatalysis. Antibacterial agents only have an antibacterial effect on bacteria on surfaces that come into contact with the antibacterial material; they have no purifying effect on food or air that doesn't come into contact with the material. Activated carbon / low-temperature catalysts / catalysts are prone to absorbing water and freezing in freezing environments, leading to blockage of internal pores, weakened adsorption and purification capabilities, and reduced efficiency in degrading harmful components in low-temperature environments. Therefore, existing refrigerator purification technologies have certain limitations in application. Summary of the Invention

[0042] Before introducing the control method of the catalyst assembly 10 according to embodiments of the present invention, it is necessary to first explain the application scenarios of the control method of the catalyst assembly 10. The control method of the catalyst assembly 10 of the present invention can be applied to various types of refrigeration equipment with air duct 30, and can be applied to smart terminals such as smartphones, tablets, and computers, and can also be applied to servers connected to refrigeration equipment. The present invention does not impose special limitations on the application scenarios, as long as they can support and implement the control method of the catalyst assembly 10.

[0043] It should be noted that in low-temperature environments, the ionization capacity of the catalyst component 10 is significantly reduced, and electronic components are easily damaged in low-temperature environments, resulting in a significant reduction in the air purification capacity.

[0044] It should be noted that the catalyst component 10 of this application can ionize air to generate active substances such as plasma, ozone, and negative ions. These active substances, including plasma, ozone, and negative ions, can kill bacteria.

[0045] According to the control method of the catalyst assembly 10 proposed in the embodiments of this application, please refer to... Figure 1 The control method for catalyst assembly 10 includes steps 100 and 200.

[0046] Step 100: Obtain the temperature of the air duct 30. Based on the temperature of the air duct 30, control the start and stop of the heating element 400 of the catalyst assembly 10. The heating element 400 is used to heat the electronic components of the catalyst assembly 10.

[0047] Step 200: Based on the fact that the temperature of the electronic components of the catalyst assembly 10 is within the operating temperature range, control the catalyst assembly 10 to start ionization or control the catalyst assembly 10 to enter the ionization preparation stage.

[0048] According to the control method of the catalyst assembly 10 in the embodiments of this application, by obtaining the temperature of the air duct 30 and controlling the start and stop of the heating element 400 according to the temperature of the air duct 30, heat is provided to the electronic components of the catalyst assembly 10, thereby ensuring that the circuit of the catalyst assembly 10 is within the normal temperature range, significantly improving the output capability of the catalyst assembly 10 that generates plasma in a low-temperature environment, and achieving a good catalytic purification effect on the air duct 30 of the refrigeration equipment.

[0049] In step 100, by acquiring the temperature of the air duct 30 in real time, the ambient temperature of the catalyst assembly 10 can be determined. By monitoring the temperature of the air duct 30 in real time and controlling the start and stop of the heating element 400 accordingly, it can be ensured that the electronic components of the catalyst assembly 10 are always within a suitable operating temperature range, regardless of changes in the external environment. This not only improves the working efficiency of the catalyst assembly 10 but also effectively extends the service life of the electronic components.

[0050] In step 200, under the heating action of the heating element 400, the temperature of the electronic components of the catalyst assembly 10 can rise. Only when the temperature of the electronic components of the catalyst assembly 10 reaches and is maintained within the optimal operating range will the system control the catalyst assembly 10 to start the ionization process. This ensures that the catalyst assembly 10 maintains the optimal operating state during the ionization process, thereby maximizing the generation of active substances such as plasma, ozone, and negative ions.

[0051] According to one embodiment of this application, the temperature of the air duct 30 is obtained, and the start and stop of the heating element 400 of the catalyst assembly 10 is controlled based on the temperature of the air duct 30, including steps 110 and 120.

[0052] Step 110: If the temperature of the air duct 30 is greater than the preset temperature, then control the heating element 400 to stop.

[0053] Step 120: If the temperature of the air duct 30 is lower than the preset temperature, then control the heating element 400 to start.

[0054] In step 110, if the detected temperature of the air duct 30 is higher than the preset temperature, it indicates that the current ambient temperature is already high enough, and the electronic components of the catalyst assembly 10 can operate normally without additional heat. By stopping the operation of the heating element 400 in a timely manner, it is possible to avoid continuing to heat when the ambient temperature is already high enough, thereby saving energy and protecting the electronic components from overheating damage.

[0055] In step 120, if the detected temperature of the air duct 30 is lower than the preset temperature, it indicates that the current ambient temperature is low, and the electronic components of the catalyst assembly 10 may not function properly. To address this issue, the system activates the heating element 400 to provide the necessary heat to the electronic components, ensuring their stable operation in low-temperature environments. By promptly activating the heating element 400 to provide heat to the electronic components, the system ensures that the catalyst assembly 10 can function normally even in low-temperature environments, preventing performance degradation or failure due to excessively low temperatures.

[0056] According to one embodiment of this application, the preset temperature is -30 degrees Celsius.

[0057] Understandably, setting the preset temperature to -30 degrees Celsius covers the low-temperature range that the refrigeration equipment may encounter in most practical applications, ensuring that the catalyst assembly 10 can operate stably in various low-temperature environments. When the temperature inside the air duct 30 drops below -30 degrees Celsius, the system will automatically activate the heating element 400 to provide the necessary heat to the electronic components of the catalyst assembly 10, ensuring that they can continue to operate normally without being affected by the low temperature. Conversely, if the temperature inside the air duct 30 is higher than -30 degrees Celsius, the heating element 400 will stop working to avoid unnecessary energy waste and potential overheating problems.

[0058] According to one embodiment of this application, if the temperature of the air duct 30 is lower than the preset temperature, the heating element 400 is activated, including step 121.

[0059] Step 121: Control the heating element 400 to heat in a cyclical interval, wherein the heating duration of the heating element 400 is 7 minutes and the interval between heating and stopping of the heating element 400 is 6 minutes.

[0060] In step 121, when the system detects that the temperature of the air duct 30 is lower than the preset -30 degrees Celsius, it will control the heating element 400 to start. However, it does not heat continuously, but adopts a "heating-interval" cycle mode. Specifically, the heating element 400 will heat continuously for 7 minutes, then stop heating for 6 minutes, and then start the next heating cycle.

[0061] By setting the heating duration and interval, overheating caused by the heating element 400 working continuously for a long time can be effectively avoided, thereby protecting the heating element 400 itself and its connected electronic components from damage.

[0062] The cyclic heating mode can be adjusted according to different ambient temperatures and airflow conditions. For example, in extremely low temperature environments, the heating time can be appropriately extended or the interval time shortened to ensure that electronic components receive sufficient heat support.

[0063] According to one embodiment of this application, the operating temperature range is [-30, 45] degrees Celsius.

[0064] Understandably, catalyst assembly 10 can achieve efficient purification within this temperature range. The [-30, 45] degree Celsius range covers environmental conditions from low temperatures to relatively warm conditions, ensuring the stability and reliability of catalyst assembly 10 in practical applications.

[0065] According to one embodiment of this application, based on the temperature of the electronic components of the catalyst assembly 10 being within the operating temperature range, the catalyst assembly 10 is controlled to initiate ionization, including step 201.

[0066] Step 201: Control the catalyst assembly 10 to ionize at cyclic intervals, wherein the ionization time of the catalyst assembly 10 during continuous ionization is 2 minutes, and the interval between stopping the ionization of the catalyst assembly 10 is 28 minutes.

[0067] In step 201, the catalyst assembly 10 does not ionize continuously, but adopts an "ionization-interval" cyclic mode. Specifically, the catalyst assembly 10 will continuously ionize for 2 minutes, then stop ionization for 28 minutes, and then start the next ionization cycle.

[0068] Prolonged continuous ionization may have adverse effects on the catalyst assembly 10, such as reducing its activity and increasing its wear. By cyclically ionizing, the catalyst assembly 10 can be given a certain rest time, reducing the damage it suffers and thus extending its service life.

[0069] By arranging appropriate intervals, the catalyst assembly 10 can maintain high activity during each ionization, thereby improving ionization efficiency. Furthermore, the ionization process can be monitored and adjusted during the intervals to further optimize the ionization effect.

[0070] Of course, the cyclic interval ionization strategy can be adjusted according to different application scenarios and needs. For example, when a large amount of air needs to be processed quickly, the interval time can be shortened or the ionization time can be extended; when the ambient temperature is low, the interval time can be increased to save energy.

[0071] According to one embodiment of this application, based on the fact that the temperature of the electronic components of the catalyst assembly 10 is within the operating temperature range, the catalyst assembly 10 is controlled to start ionization, including steps 210, 220 and 230.

[0072] Step 210: Obtain the operating status of the fan 40 in the air duct 30.

[0073] Step 220: If the blower 40 is in use, control the catalyst assembly 10 to start ionization.

[0074] Step 230: If the blower 40 is in the off state, then control the catalyst assembly 10 not to start.

[0075] In step 210, the operating status of the fan 40 in the air duct 30 is acquired in real time. Specifically, the operating status of the fan 40 can be obtained by acquiring the fan control signal from the refrigeration equipment controller.

[0076] In step 220, after obtaining the operating status of the fan 40, if the fan 40 is in use (i.e., running), it means that there is airflow in the air duct 30. At this time, the catalyst assembly 10 will have a better effect on air purification and improve the overall energy utilization efficiency.

[0077] In step 230, after obtaining the operating status of the fan 40, if the fan 40 is in the off state (i.e., not running), it indicates that there is no airflow or the airflow volume is very small in the air duct 30. In this case, starting the catalyst assembly 10 for ionization treatment will not be effective. Therefore, the system will control the catalyst assembly 10 not to start the ionization process to save energy and extend the equipment life.

[0078] According to one embodiment of this application, before obtaining the temperature of the air duct 30 and controlling the start / stop of the heating element 400 of the catalyst assembly 10 based on the temperature of the air duct 30, steps 010 and 020 are included.

[0079] Step 010: Determine that the refrigeration equipment is in refrigeration mode, and obtain the temperature of the air duct, or Step 020: Determine that the refrigeration equipment is in defrost mode, and obtain the temperature of the air duct after the defrost mode ends and a preset time has elapsed.

[0080] In step 010, by determining that the refrigeration equipment is in refrigeration mode, it can be ensured that the subsequent ionization steps are performed in a safe environment, and ionization purification can be performed normally.

[0081] The defrost signal is used to monitor the defrost status of the refrigeration equipment in real time. The defrost signal is emitted by the refrigeration equipment when it detects frost on the evaporator surface and requires defrosting.

[0082] In step 020, once it is determined that the refrigeration device is in the defrost mode, the control catalyst assembly 10 is made to wait until the defrost mode ends before starting. This is because during the defrost process, the refrigeration device temporarily stops refrigerating, and at the same time, a large amount of moisture or humidity may be released, which will have an adverse effect on the ionization effect of the catalyst assembly 10 and may even damage the catalyst assembly 10. Therefore, stopping ionization during defrost is a necessary protective measure. By setting a reasonable preset duration, a certain buffer time can be given to the catalyst assembly 10 after defrost to avoid the adverse effects it may suffer when immediately starting the ionization process. This helps to extend the service life of the catalyst assembly 10 and improve its working stability and reliability.

[0083] When the defrost signal ends, it indicates that the defrost operation of the refrigeration device has been completed. At this time, the system starts a timer and waits for a preset duration. This preset duration is to ensure that the refrigeration device has fully returned to its normal working state, and the temperature, humidity, etc. conditions in the air duct 30 have stabilized, and the water vapor on the catalyst assembly 10 has been evaporated or ionized, making the overall environment suitable for the catalyst assembly 10 to restart, reducing the possibility of water condensing and freezing at the tip of the electrode 100.

[0084] When the timer reaches the preset duration, the system believes that the environmental conditions at this time meet the requirements for the catalyst assembly 10 to restart ionization. Then, the subsequent steps are executed, that is, the temperature of the air duct 30 is acquired, and the start and stop of the heating element 400 of the catalyst assembly 10 are controlled according to the temperature of the air duct 30. By controlling the start and stop of the heating element 400, the catalyst assembly 10 is maintained to operate within the working temperature range, thereby ensuring its ionization effect and purification efficiency.

[0085] According to an embodiment of the present application, the preset duration is 30 s.

[0086] It can be understood that during the defrost process of the refrigeration device, refrigeration will be temporarily stopped and a large amount of moisture or humidity will be released. The dissipation of this moisture and humidity and the re-stabilization of the temperature and humidity in the air duct 30 require a certain amount of time. The preset duration of 30 seconds can ensure that within this period, the environmental conditions in the air duct 30 can return to a state suitable for the catalyst assembly 10 to restart ionization.

[0087] According to the catalyst assembly 10 provided by the embodiment of the present application, please refer to Figure 2 or Figure 3The catalyst assembly 10 includes an electrode 100, a power supply 300, a heating element 400, and a controller. The electrode 100 includes a first electrode plate 110 and a second electrode plate 120 spaced apart. The first electrode plate 110 is provided with at least one discharge element 111. The discharge element 111 and the second electrode plate 120 are adapted to form an ionization electric field. The power supply 300 is electrically connected to the first electrode plate 110 and the second electrode plate 120. The heating element 400 is connected to the power supply 300 and is used to heat the electronic components of the catalyst assembly. The controller is used to execute the control method of the catalyst assembly 10 described above.

[0088] It is understood that the electrode 100 is composed of a first electrode plate 110 and a second electrode plate 120 spaced apart, forming a stable electric field environment between the first electrode plate 110 and the second electrode plate 120. At least one discharge component 111 is disposed on the first electrode plate 110, and these discharge components 111 work in conjunction with the second electrode plate 120 to form an ionizing electric field. Under the action of the electric field, molecules or atoms in the air are ionized, generating charged particles, thereby helping to remove pollutants from the air.

[0089] The power source 300 is the energy source for the catalyst assembly 10. It is electrically connected to the first electrode plate 110 and the second electrode plate 120 to provide the electrical energy required for the ionization process.

[0090] The heating element 400 is connected to the power supply 300 and generates heat through the power supply 300. This heat is used to heat the power supply 300 itself or other electronic components that require heating. The heating element 400 helps maintain the catalyst assembly 10 within a suitable operating temperature range, thereby improving the efficiency of ionization and catalysis.

[0091] The controller is responsible for executing the above-described control method for the catalyst assembly 10. By receiving signals from sensors (such as the temperature of the air duct 30, defrosting signals from the refrigeration equipment, etc.), the controller can intelligently adjust parameters such as the discharge state of the electrode 100 and the heating power of the heating element 400 to ensure that the catalyst assembly 10 always operates in the optimal state.

[0092] In one embodiment, the second electrode sheet 120 is provided with a ventilation hole 121, and the catalyst assembly 10 includes a first housing 610 and a second housing 620. The first housing 610 and the second housing 620 are snap-fitted together, and an installation space 601 is formed between the first housing 610 and the second housing 620. The electrode 100, the power supply 300, and the heating element 400 are located in the installation space 601. The tip of the discharge component 111 is directly opposite the center of the ventilation hole 121, which confines the discharge to the hollow edge. The discharge component 111 is kept at a distance from the first housing 610 and the second housing 620 to prevent sparking from igniting the surrounding plastic parts.

[0093] According to one embodiment of this application, please refer to Figure 2 The power supply 300 includes a circuit board 340, which is provided with a low-voltage input circuit 310, a transformer 320 and a high-voltage output circuit 330 connected in sequence. The high-voltage output circuit 330 is connected to the first electrode plate 110 and the second electrode plate 120. The heating element 400 is disposed on the side of the transformer 320 near the low-voltage input circuit 310 and is powered by the low-voltage input circuit 310.

[0094] One end of the circuit board 340 is equipped with a low-voltage input circuit 310, which is the input terminal of the power supply 300. This circuit is responsible for receiving low-voltage electrical energy from the external power supply 300 and transmitting it to subsequent circuit components. The transformer 320 can convert the input low-voltage electrical energy into high-voltage electrical energy. The output terminal of the transformer 320 is connected to the high-voltage output circuit 330, and the generated high-voltage electrical energy is transmitted to the first electrode plate 110 and the second electrode plate 120.

[0095] The heating element 400 is positioned on the side of the transformer 320 closest to the low-voltage input circuit 310, which facilitates heat transfer and utilization, ensuring that the transformer 320 is heated while preventing the high voltage from affecting the heating element. The input terminals of the heating element are powered through the low-voltage input circuit 310, ensuring that the heat from the heating element is quickly transferred to the electronic components in the low-voltage section through the circuit wires, keeping their temperature within the normal operating range.

[0096] According to one embodiment of this application, please refer to Figure 3 The power supply 300 includes a circuit board 340. On the first side of the circuit board 340, a low-voltage input circuit 310, a transformer 320, and a high-voltage output circuit 330 are connected in sequence. The high-voltage output circuit 330 is connected to the first electrode plate 110 and the second electrode plate 120. The heating element 400 is fixed to the second side of the circuit board 340 by insulating glue 500. The first side and the second side of the circuit board 340 are opposite to each other. The heating element 400 is powered by the low-voltage input circuit 310.

[0097] Understandably, circuit board 340 provides a platform for the orderly arrangement and connection of various circuit components. On the first side of circuit board 340, low-voltage input circuit 310, transformer 320, and high-voltage output circuit 330 are sequentially electrically connected. A heating element 400 is located on the second side of circuit board 340. The input terminals of the heating element are powered through low-voltage input circuit 310, ensuring that the heat from the heating element is quickly transferred to circuit board 340 and the low-voltage input circuit 310, transformer 320, and high-voltage output circuit 330 located on the first side of circuit board 340, ensuring that their temperatures remain within the normal operating range.

[0098] According to the refrigerator of the third aspect embodiment of this application, please refer to Figure 4 The refrigerator includes a cabinet 20 and the catalyst assembly 10 mentioned above. An air duct 30 is provided inside the cabinet 20; the catalyst assembly 10 is disposed in the air duct 30.

[0099] It should be noted that the refrigerator of this application has all the technical effects of the catalyst assembly 10 mentioned above, since it includes the catalyst assembly 10 mentioned above, and will not be repeated here.

[0100] Understandably, the airflow through the duct 30 passes sequentially through the first electrode plate 110 and the second electrode plate 120. The catalyst assembly 10 can sterilize and purify the airflow, effectively removing bacteria and odors. Through the duct 30, the air inside the housing 20 can circulate, ensuring that the air inside the entire housing 20 is thoroughly sterilized and purified.

[0101] In one embodiment, a fan 40 is provided in the air duct 30 to generate airflow. The operation of the fan 40 will make the airflow smoother and enhance the sterilization and purification effect.

[0102] According to one embodiment of the present invention, the side of the catalyst assembly 10 closest to the power source 300 is connected to the side wall of the air duct 30, and the side of the catalyst assembly 10 furthest from the power source 300 is tilted toward the ground at a set angle.

[0103] It is understandable that the refrigerator's air duct 30 is prone to a humid environment. Tilting the catalyst assembly 10 can prevent condensation from entering the power supply 300 side of the catalyst assembly 10. If the power supply 300 is exposed to a humid environment (such as during refrigerator defrosting), it may cause a short circuit or malfunction. By tilting the catalyst assembly 10 away from the power supply 300, the chance of liquid entering the power supply 300 can be reduced, improving the stability and reliability of the power supply 300.

[0104] According to the control device of the catalyst assembly 10 provided in the embodiments of this application, please refer to Figure 5 It includes a first control module and a second control module.
