Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, for example to a purification control method and purification control device for a refrigerator, and a refrigerator. Background Technology

[0002] Currently, users' functional needs for refrigerators are no longer limited to basic refrigeration and freezing; they are also increasingly concerned about the hygiene and health of the storage environment. The relatively enclosed interior of a refrigerator has poor air circulation, and the diverse types of food stored there make it easy for microorganisms (such as bacteria and mold) to grow, producing mixed odors that affect food preservation and user experience.

[0003] In related technologies, in order to solve the above problems, purification devices that utilize principles such as photocatalytic sterilization or plasma have been designed. These purification devices generate active substances with strong oxidizing properties, which decompose odors in the refrigerator compartment and inactivate microorganisms, thereby achieving purification and deodorization of the refrigerator compartment.

[0004] In the process of implementing the embodiments of this disclosure, it was found that the related technology has at least the following technical problems: Refrigerators in related technologies typically use a refrigeration fan to force air circulation, promoting contact between active substances and contaminants. In the refrigerator's control strategy, the refrigeration fan and compressor operate synchronously, but the compressor's operating time within a control cycle is relatively short (e.g., running for 10 minutes and then stopping for 50 minutes). This results in the purification device being ineffective for most of the time, with a short purification and deodorization period and poor purification and deodorization effect inside the refrigerator compartment.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0031] Combination Figure 1 As shown, this embodiment of the present disclosure provides a refrigerator 100, including: a cabinet 110, an air duct 120 for supplying air to the compartments, a fan 130, a purification device 200 for sterilization and deodorization, and a purification control device 500 (600) for the refrigerator. The cabinet 110 includes a compartment 111 for accommodating items to be stored. The air duct 120 communicates with the compartment 111. The purification device 200 is installed in the air duct 120. The purification control device 500 (600) for the refrigerator is disposed in the cabinet 110.

[0032] Optionally, the purification device 200 can be a plasma deodorization device, a negative ion sterilization device, an ultraviolet sterilization device, or an ozone deodorization device, etc.

[0033] Combination Figure 2 As shown, taking a plasma deodorizing device as an example, in some embodiments, the purification device 200 includes: a support member 210, a lamp panel 220, and a catalyst block 230. The support member 210 is detachably mounted within the air duct 112 and is provided with claws 211 for fixing the lamp panel 220 and the catalyst block 230. The lamp panel 220 and the catalyst block 230 are mounted to the support member 210 via the claws 211.

[0034] Optionally, the claws 211 on the support member 210 for mounting the lamp panel 220 include lamp panel limiting posts for positioning the lamp panel 220; fixing grooves for fixing the lamp panel 220; wire grooves for straightening; and mounting and disassembling protrusions for providing a point of force, which can be bent outward to cause deformation, facilitating the installation and removal of the lamp panel 220, and also playing a supporting and balancing role to prevent the support member 210 from tipping over.

[0037] Optionally, such as Figure 3 The catalyst block 230 shown is a honeycomb ceramic block, which provides a base for the photocatalytic material to adhere. The photocatalytic material is composed of titanium dioxide and tungsten trioxide in a ratio of 1:9 to 9:1, and is attached to the surface of the honeycomb ceramic block to generate active substances to remove odors and microorganisms.

[0038] Optionally, the catalyst block 230 also includes a shock-absorbing sponge, which is adhered to the honeycomb ceramic block to absorb shock between the honeycomb ceramic block and the support, reduce damage from hard impacts, and facilitate the installation of the honeycomb ceramic block into the support.

[0039] Optionally, the purification control device 600 for the refrigerator includes a processor. During deodorization and sterilization of the refrigerator compartments, the processor can acquire the refrigerator's operating status. When the refrigerator is in the cooling phase, the processor can control the lamp panel to irradiate the catalytic block. After the cooling phase ends, the processor controls the refrigerator's cooling fan and lamp panel to operate intermittently according to a preset program until the next cooling phase is reached.

[0040] In conjunction with the refrigerator described above, this disclosure provides a purification control method for a refrigerator, wherein the processor described above can be the executing entity of the purification control method. Figure 4 As shown, the purification control method includes: S401, the processor obtains the operating status of the refrigerator.

[0041] The refrigerator's operating status includes a cooling phase and a non-cooling phase. The cooling phase refers to the stage where the refrigerator compartment temperature reaches the start-up temperature, and the compressor and cooling fan operate to cool the compartment.

[0042] Specifically, the processor can obtain the compartment temperature through a temperature sensor located inside the refrigerator compartment, and compare the compartment temperature with the start-up and stop temperatures to determine whether the refrigerator is in the cooling stage. The processor can also directly determine whether the compressor is powered on or off by feedback signals from a current sensor and compressor relay, thus determining whether the refrigerator is in the cooling stage.

[0043] S402, the processor controls the operation of the purification device when the refrigerator is in the cooling stage.

[0044] Specifically, taking the above-mentioned purification device as an example, the operation of the purification device is controlled and the lamp plate is turned on to irradiate the catalyst block.

[0045] Specifically, when the refrigerator is in the cooling phase, the compressor operates to cool the air, and the cooling fan works simultaneously to blow cold air into the compartments. In this situation, controlling the purification device allows the existing airflow from the fan, which is used for cooling, to force the air inside the compartment through the purification device in the duct. This allows odor molecules, bacteria, and viruses in the air to be decomposed and killed by the purification device, thus purifying the air inside the refrigerator in real time during the cooling process. This effectively removes odors, keeps the air inside the refrigerator fresh, and reduces the growth of microorganisms. In this way, purification and deodorization can be performed without increasing the energy consumption of the additional fan.

[0046] S403, after the cooling stage ends, the processor controls the refrigerator's fan and purification device to run intermittently according to a preset program until the next cooling stage is reached.

[0047] Specifically, after the refrigerator completes one cooling cycle, the compressor stops working, and the temperature of the refrigerator compartment gradually stabilizes and remains near the set temperature for a period of time. This period is the window period for purification and deodorization. In this embodiment, by controlling the fan and purification device to operate intermittently according to a preset program during this period, the purification and deodorization can be extended from a small part of the entire cooling cycle to almost the entire cooling cycle, thereby improving the overall purification and deodorization effect on the refrigerator compartment.

[0048] Furthermore, after the cooling phase ends, the refrigerator's cooling fan operates intermittently according to a preset program. This allows the fan to blow over the evaporator, which has not yet returned to room temperature, and the frost on its surface. This effectively utilizes the residual cold energy to slightly cool the refrigerator compartments, slowing down the temperature rise and indirectly reducing the compressor's subsequent start-up frequency and operating time. Additionally, the fan blows relatively warmer air from the compartments towards the low-temperature evaporator, promoting the natural melting of the frost layer on its surface. This helps reduce or eliminate the need for independent electric defrosting, further achieving energy savings.

[0049] In this embodiment of the present disclosure, during the purification and deodorization process of the refrigerator compartment, in addition to controlling the operation of the purification device during the refrigerator's cooling phase to ensure sufficient contact between the active substances generated by the purification device and the pollutants in the refrigerator compartment, the refrigerator's cooling fan and purification device are also controlled to operate intermittently according to a preset program after the cooling phase ends, until the next cooling phase is reached. This prolongs the contact time between the active substances and the pollutants in the refrigerator compartment. Therefore, this embodiment of the present disclosure can increase the duration of the purification device's effective state and improve the purification and deodorization effect in the refrigerator compartment.

[0050] In some embodiments, after the cooling phase ends, the fan and purification device are controlled to operate intermittently according to a preset program, including: after a set delay, obtaining the room temperature; if the room temperature rises by a first temperature compared to the temperature when the fan was last stopped, controlling the fan and purification device to operate; if the room temperature drops by a second temperature compared to the temperature when the fan was running, turning off the fan and purification device; repeating the above steps until the room temperature reaches the start-up temperature.

[0051] Specifically, immediately after the cooling phase ends, the surface temperature of the evaporator and the temperature inside the chamber are extremely low. Immediately starting the fan could blow excessively cold air into the chamber, potentially causing food to freeze. Furthermore, the air cleanliness inside the chamber is relatively high, so purification is not urgent. Therefore, it is necessary to delay the set time and then monitor the chamber temperature to determine whether the fan and purification device can be activated.

[0052] Optionally, the duration can be set to 5 to 10 minutes.

[0053] Specifically, if the room temperature has risen by a certain amount compared to when the fan was last shut down, it indicates a significant temperature increase within the room, and during this temperature rise, biological contaminants such as microorganisms or odors in the room are increasing again. Therefore, it is necessary to start the fan to promote air circulation and activate the purification device to purify the air.

[0054] Optionally, the first temperature is 1 ℃ to 1.5 ℃.

[0055] Specifically, if the room temperature drops by a second temperature compared to the temperature when the fan is running, it indicates that the fan operation has reduced the room temperature to a certain extent, and biological pollutants such as microorganisms and odors have been further purified. At this time, turning off the fan and purification device can avoid excessive cooling and unnecessary energy consumption.

[0056] Optionally, the second temperature is 0.5 ℃ to 1 ℃, and the second temperature is less than the second temperature.

[0057] Specifically, by continuously repeating the steps described above to control the operation of the fan and purification device based on changes in compartment temperature, the refrigerator can flexibly adjust the operating status of the equipment according to actual temperature requirements after the cooling operation phase ends, so that the refrigerator compartment can maintain a certain purification and deodorization effect while minimizing energy consumption and achieving energy-saving operation.

[0058] In this embodiment, after the cooling phase ends, the room temperature is monitored by delaying the set time. The fan and purification device are activated when the temperature rises to a first temperature and shut off when the temperature drops to a second temperature. This intermittent operation not only achieves precise control of the refrigerator's actual temperature requirements and avoids over-cooling, but also utilizes the purification device to continuously purify the air and remove odors and microorganisms when the temperature fluctuates.

[0059] In some embodiments, controlling the operation of the fan includes: determining the current number of times the fan is started and stopped during this intermittent operation phase; determining a target speed based on the current number of starts and stops; and controlling the fan to operate at the target speed.

[0060] Specifically, during the non-cooling phase, the system undergoes multiple heating and cooling processes for purification, which places high demands on the lifespan of the fan. By determining the target speed based on the current number of start-stop cycles during this intermittent operation phase and controlling the fan to operate at the target speed, the lifespan of the fan can be extended.

[0061] Specifically, during the non-cooling phase, as the number of times the fan starts and stops increases, the refrigerator compartments gradually become cleaner, and the need for purification decreases. Therefore, the fan speed can be slightly lower for the second purification compared to the first, and even slightly lower for the third, and so on. Thus, the target fan speed can be determined based on the current number of on / off cycles.

[0062] Alternatively, the target speed can be determined based on the current number of start-stop cycles according to the following expression: ; in, Let N be the target rotational speed, and N be the current number of starts and stops. α is the rated speed of the fan, and α is the speed reduction coefficient.

[0063] In this embodiment, during the non-cooling phase, the fan speed is adjusted according to the current number of times the fan is turned on and off. This can meet the cooling and purification needs of the refrigerator at different times, and avoid the reduction in lifespan and energy waste caused by the fan running at high speed continuously.

[0064] In some embodiments, before controlling the operation of the purification device when the refrigerator is in the cooling stage, the purification control method further includes: acquiring biological pollution parameters in the compartment; determining the pollution level in the compartment based on the biological pollution parameters; determining to execute the step of controlling the operation of the purification device when the refrigerator is in the cooling stage when the pollution level reaches a set level; and controlling the fan and purification device to operate intermittently according to a preset program after the cooling stage ends, until the next cooling stage is reached.

[0065] Specifically, biological pollution parameters are indicators that reflect the degree of biological pollution in an indoor space, such as odor parameters and microbial parameters.

[0066] Specifically, these parameters can be obtained by installing corresponding sensors in the room. For example, a bacterial sensor can be installed to detect the concentration of microorganisms in the room, and an odor sensor can be installed to detect the content of odor molecules.

[0067] Specifically, after obtaining the biological contamination parameters, the contamination level of the room can be determined by comparing these parameters with the standards for each contamination level. For example, the contamination level can be divided into multiple levels (such as Level 1, Level 2, etc.), with different levels corresponding to different ranges of contamination severity. For instance, when the number of microorganisms is within the first range, it is determined to be Level 1, indicating a relatively light level of contamination; when the number of microorganisms exceeds the upper limit of the first range, it is determined to be Level 2, indicating a relatively heavy level of contamination. In this way, corresponding purification measures can be taken according to different contamination situations, which is beneficial to improving purification efficiency and targeting.

[0068] Optionally, the biological pollution parameters include odor parameters and microbial parameters; determining the pollution level of the room based on the biological pollution parameters includes: determining the pollution level as Level 1 when the odor parameter or microbial parameter is greater than or equal to a first threshold and less than a second threshold; determining the pollution level as Level 2 when the odor parameter or microbial parameter is greater than or equal to the second threshold; and determining the pollution level as Level 3 when both the odor parameter and microbial parameter are greater than or equal to the second threshold; wherein, the Level 2 is set, Level 3 is higher than Level 2, and Level 2 is higher than Level 1.

[0069] Specifically, when the contamination level in the compartment reaches a set level, it indicates a relatively high degree of biological contamination. In this case, simply controlling the purification device during the refrigerator's cooling phase is insufficient to completely remove the biological contamination. Therefore, in this situation, it can be determined that after the cooling phase ends, the fan and purification device need to be operated intermittently according to a preset program until the next cooling phase is reached.

[0070] In this embodiment, when the refrigerator is in the cooling phase, the purification device is not directly controlled to operate. Instead, biological pollution parameters within the compartment are first acquired to determine the pollution level. Then, based on the actual pollution level, it is decided whether to activate the purification function and whether to adopt an intermittent operation mode subsequently. This avoids unnecessary energy consumption while ensuring that the air quality inside the refrigerator can be effectively improved when needed.

[0071] In some embodiments, the purification control method further includes: determining that the purification device is controlled to operate only during the cooling stage when the pollution level is lower than a set level; and controlling the purification device to operate at maximum intensity, controlling the fan to operate at maximum speed, and outputting alarm prompt information when the pollution level is higher than the set level.

[0072] Specifically, when the pollution level in the compartment is determined to be lower than the set level, it indicates that there is some biological contamination in the compartment, but the degree is relatively mild. In this case, controlling the operation of the purification device during the refrigeration phase of the refrigerator can effectively remove the biological contamination in the compartment.

[0073] Specifically, when the pollution level in a room exceeds a set level, it indicates that the biological contamination within the room is extremely severe. In this case, simply controlling the operation of the purification device is insufficient to meet the purification and deodorization requirements. Therefore, in addition to controlling the purification device to operate at maximum intensity and the fan to operate at maximum speed, it is also necessary to output an alarm message to prompt the user to remove the source of biological contamination in the room.

[0074] In some embodiments, before controlling the operation of the purification device, the purification control method further includes: identifying the category of items to be stored in the room; and increasing the basic operating intensity of the purification device and the basic speed of the fan when there are items of a strong odor category.

[0075] Specifically, a camera capable of capturing images of stored items within the room, along with an odor sensor, is installed in the room. The processor can capture images of the items through the camera and odor parameters within the room through the odor sensor, and then identify the food category of the items in the room based on the item images and odor parameters.

[0076] Specifically, if there are strongly odorous food items in the room, it indicates that the original operating intensity of the purification device and the speed of the fan are insufficient to effectively remove odors and microorganisms. Therefore, in this case, it is necessary to increase the basic operating intensity of the purification device and the basic speed of the fan.

[0077] In this embodiment, before controlling the operation of the purification device, it is first determined whether there are any strongly odorous food items in the room. If so, the basic operating intensity of the purification device and the basic speed of the fan are increased. This helps to improve the purification and deodorization effect on the room.
