Detailed Description
In general, the temperature and humidity of the refrigerator directly affect the quality of stored articles (foods) to cause the quality of the stored articles to change, so that taste and bacteria are generated, and therefore, reasonably controlling the temperature and humidity of the refrigerator can slow down the speed of food quality deterioration, but the food storage time is too long, and the quality of the foods can change, so that some schemes are already presented at present, a deodorizing and sterilizing module is introduced into the refrigerator, and deodorizing and sterilizing are performed in the running process of the refrigerator, so as to ensure the quality of the foods. However, frequent turning on of the sterilization module may have an influence on the health of the user, so it becomes important to reasonably control the operation of the sterilization module.
Therefore, the embodiment of the application provides an air-cooled refrigerator and a sterilization method thereof.
Fig. 1 shows a schematic block diagram of an air-cooled refrigerator 10 according to an embodiment of the present application. The air-cooled refrigerator 10 may generally include a cabinet, a refrigeration system, a detection device 120, a sterilization device 130, and a controller 150. The cabinet defines a storage compartment 110 (which may be a refrigeration compartment, in particular). The refrigeration system includes a blower 140 for generating and delivering a flow of refrigeration gas for the storage compartment 110. Of course, the refrigeration system may also include a compressor, an evaporator, etc., as will be known to those skilled in the art and will not be described in detail. The detection device 120 may be disposed within the storage compartment 110 or at any other suitable location for detecting an operational status parameter of the storage compartment 110. The sterilizing device 130 is used for releasing sterilizing substances (such as sterilizing ions, sterilizing gas, etc.), and the sterilizing substances can be spread by the air flow driven by the fan 140 to perform deodorizing and sterilizing on the storage compartment 110 or the whole inside of the air-cooled refrigerator 10. Preferably, the sterilizing device 130 may be disposed at a neighboring position downstream of the blower 140 or in an air flow path (e.g., an air supply duct providing a cooling air flow to the storage compartment 110), and the diffusion efficiency of the sterilizing material generated by the sterilizing device 130 is improved by the air flow delivery, thereby improving the deodorizing and sterilizing efficiency. The controller 150 may be connected to the blower 140, the detecting device 120, and the sterilizing device 130, respectively. The controller 150 may include a memory 151 and a processor 152. The memory 151 has stored therein computer program code which, when executed by the processor 152, causes the controller 150 to perform a sterilization method of the air-cooled refrigerator described below. Note that, the connection relationship between the respective members is only schematically shown in fig. 1, and the actual positional relationship between the members is not limited. In addition, the tank and the refrigeration system are not shown in fig. 1 in order not to obscure and obscure the inventive aspects of the present application, but the structure and arrangement of the tank and the refrigeration system should be known to those skilled in the art.
Specifically, the processor 152 may be an MCU (Microcontroller Unit, micro control unit) connected to the sterilization device 130 through VCC (power supply voltage), GND (ground), CTRL (control) and FD (feedback) four wires, and connected to the blower 140 through VCC, FD, PWM (pulse width modulation) and GND four wires. The detection device 120 communicates with the processor 152 via an I2C (Integrated-Circuit) bus.
Accordingly, the embodiment of the present application also provides a sterilization method of an air-cooled refrigerator, which is applied to the air-cooled refrigerator 10 of the present application and can be executed by the controller 150. Fig. 3 is a flow chart schematically showing a sterilization method of an air-cooled refrigerator according to an embodiment of the present application. Referring to fig. 3, the sterilization method may include at least the following steps S302 to S308.
In step S302, after the cooling system of the air-cooled refrigerator 10 starts to operate each time, an indication signal indicating that the fan 140 of the cooling system is stably operating is obtained.
In this step, the indication signal may be determined by detecting an operation state parameter (such as voltage or rotation speed) of the fan 140, and when the operation state parameter of the fan 140 reaches a set range, it is determined that the fan 140 is stably operated. For example, upon detecting that the rotational speed of the blower 140 is within a set rotational speed range (e.g., 990-1500 rpm), the blower 140 is determined to be operating steadily. When the fan 140 is in a stable running state, the sterilizing substances can be guaranteed to be rapidly and effectively uniformly diffused, the sterilizing effect is guaranteed, and meanwhile, health risks caused by overhigh local concentration are avoided.
In step S304, the operation state parameters of the storage compartment 110 are obtained.
In step S306, it is determined whether the starting condition of the sterilization device 130 is met according to the operation state parameters of the storage compartment 110. If yes, go to step S308.
In step S308, the sterilization device 130 is started to operate in a preset manner. The preset mode of operation of the sterilization apparatus 130 in this step is not particularly limited, as long as the sterilization apparatus 130 can perform a necessary sterilization function to perform deodorization and sterilization on the inside of the air-cooled refrigerator 10.
In this embodiment, the sterilization device 130 can be dynamically and reasonably controlled to be started according to the operation state parameters of the storage compartment 110, so that the sterilization effect is ensured, the utilization efficiency of the sterilization device 130 is improved, and the problems that the sterilization module is frequently started, the health of a user is affected and energy is wasted due to the fixed starting conditions of the sterilization module of the refrigerator in the prior art are solved.
In one embodiment, the sterilization device 130 may be configured to controllably operate in a sterilization mode, a heating mode, or a shutdown mode. The sterilizing device 130 is activated to generate sterilizing substances to perform deodorization sterilization in the sterilization mode. The sterilizing device 130 generates heat to remove condensation in the heating mode. The sterilization device 130 stops operating in the shutdown mode. Accordingly, step S308 may be further implemented as: the sterilization device 130 is controlled to cyclically operate in a cyclically alternating manner of a stop mode, a sterilization mode, and a heating mode. By cyclically alternating the shutdown mode, the sterilization mode and the heating mode, the sterilization device 130 can be temporarily suspended after being operated in the sterilization mode and the heating mode, so that energy is accumulated for the next operation, the normal operation of the sterilization device 130 is ensured, and the service life of the sterilization device is prolonged.
Further, in step S308, the sterilization device 130 may be controlled to operate cyclically in a cyclically alternating manner of the shutdown mode, the sterilization mode and the heating mode according to a preset cycle parameter. The cycle parameters herein include respective durations during which the sterilization device 130 operates in the shutdown mode, the sterilization mode, and the heating mode in the cycle of the sterilization device 130. For example, if the duration of the preset shutdown mode is T1 seconds, the duration of the sterilization mode is T2 seconds, the duration of the heating mode is T3 seconds, the sterilization device 130 is started and then is suspended in the shutdown mode for T1 seconds, then is operated in the sterilization mode for T2 seconds, then is operated in the heating mode for T3 seconds, then is operated in the shutdown mode for T1 seconds, and so on. The preset time period T1 of the shutdown mode, the time period T2 of the sterilization mode, and the time period T3 of the heating mode may be set according to the actual situation and the application requirement of the sterilization device 130 and the air-cooled refrigerator 10, which is not particularly limited in the present application.
In one embodiment, referring to fig. 4, before performing step S304, the sterilization method of the air-cooled refrigerator of the present application may further include the steps of:
in step S303, it is determined whether the refrigeration system is operated for the first time after the air-cooled refrigerator 10 is powered on. That is, it is determined whether the refrigeration system is in the first cooling cycle after the air-cooled refrigerator 10 is powered on. If not, the step S304 is continued. If yes, step S310 is executed.
Specifically, the flag bit indicating that the refrigeration system has completed the first refrigeration operation can be generated according to the recorded first start time and the first stop time of the refrigeration system by recording the first start time and the first stop time of the refrigeration system when the air-cooled refrigerator 10 is powered on each time (including the first power on and the power off and then powered on). The flag bit is cleared after the refrigerator is powered off. Thus, in step S303, it is determined whether the cooling system is operated for the first time after the air-cooled refrigerator 10 is powered up by determining whether the flag is present. If the flag bit does not exist currently, the refrigeration system is judged to be operated for the first time after the air-cooled refrigerator 10 is powered on. If the flag bit is present, it is determined that the refrigeration system is not operated for the first time after the air-cooled refrigerator 10 is powered on.
In step S310, the sterilization device 130 is started to operate in the above-mentioned preset manner until the refrigeration system is turned off. Since the refrigerator generally transitions from a high temperature (much higher than the storage temperature of the storage compartment) to a low temperature state during the first cooling cycle after the refrigerator is powered up, the risk of deterioration and decay of the stored items in this case increases greatly, and thus the sterilization device 130 is continuously operated in a preset manner during the first cooling cycle until the cooling system is turned off. The preset mode of operation of the sterilization device 130 in this step is the same as that in step S308, and will not be described here again.
In this embodiment, by controlling the sterilizing device 130 to continuously operate in a preset manner until the refrigerating system is turned off when the refrigerating system is operated for the first time after the air-cooled refrigerator 10 is powered on, cleanliness in the storage compartment 110 in the first refrigerating cycle after the air-cooled refrigerator 10 is powered on is ensured, and the risk of deterioration and decay of stored articles due to high temperature in the initial stage of power on is greatly reduced.
The scheme of the application can dynamically start the sterilizing device 130 according to the operation state parameters of the storage compartment 110 of the air-cooled refrigerator 10. The operational parameters of the storage compartment 110 herein refer to parameters that characterize the storage conditions of the articles in the storage compartment 110, and the rate of deterioration of the articles under different storage conditions is different, and thus the need for sterilization is different. In one embodiment, referring to fig. 2, the detection device 120 of the air-cooled refrigerator 10 may include a temperature sensor 121 and a pressure sensor 122. The temperature sensor 121 may be provided in the storage compartment 110, for example, for detecting the temperature of the storage compartment 110. The pressure sensor 122 may be provided at a lower portion of a rack or shelf of the storage compartment 110, for example, and calculate the weight of the stored goods in the storage compartment 110 from the sensed pressure.
Accordingly, in the sterilization method of the air-cooled refrigerator, the operation state parameters of the storage compartment 110 acquired in step S304 may include the temperature of the storage compartment 110 and the weight of the stored articles. Which are obtained by the aforementioned temperature sensor 121 and pressure sensor 122, respectively. Further, the activation condition of the sterilization device 130 in step S306 may include that the temperature of the storage compartment 110 is greater than or equal to the preset temperature threshold and the weight of the stored articles is greater than or equal to the preset weight threshold. Since the higher the temperature, the faster the deterioration and decay speed of the articles, and the more the articles are stored, the more the heat and moisture are released from the articles, and the greater the deterioration and decay speed and probability of the articles, and when the amount of the articles stored is very small or even none, frequent sterilization is not needed, the sterilization device 130 is started to sterilize when the temperature of the storage compartment 110 and the weight of the articles stored reach respective preset thresholds, thereby effectively improving the utilization efficiency of the sterilization device 130 and reducing unnecessary energy consumption.
Further, in one embodiment, with continued reference to fig. 2, the detection device 120 of the air-cooled refrigerator 10 may further include a humidity sensor 123. The humidity sensor 123 may be provided in the storage compartment 110, for example, for detecting the humidity of the storage compartment 110. In a specific embodiment, the humidity sensor 123 may be integrated with the temperature sensor 121, so that the temperature and humidity detection is performed by the same temperature and humidity sensor.
Accordingly, in the sterilization method of the air-cooled refrigerator, the operation state parameter of the storage compartment 110 acquired in step S304 may further include the humidity of the storage compartment 110. Furthermore, the starting condition of the sterilization device 130 in step S306 may further include that the humidity of the storage compartment 110 is greater than or equal to the preset humidity threshold. That is, in this case, it is necessary to simultaneously satisfy that the temperature of the storage compartment 110 is greater than or equal to the preset temperature threshold, the weight of the stored articles in the storage compartment 110 is greater than or equal to the preset weight threshold, and the humidity of the storage compartment 110 is greater than or equal to the preset humidity threshold, so as to start the sterilization device 130 for sterilization. Since humidity is also an important factor affecting the deterioration of the articles, the higher the humidity is, the faster the deterioration of the articles is, so that the starting judgment of the sterilization device 130 is more accurate and reasonable by increasing the judgment of whether the humidity of the storage compartment 110 satisfies the starting condition of the sterilization device 130.
The preset temperature threshold value, the preset weight threshold value, and the preset humidity threshold value may be set according to the actual situation and the application requirement of the sterilizing device 130 and the air-cooled refrigerator 10, which is not particularly limited in the present application.
In one embodiment, before controlling the sterilization apparatus 130 to cyclically operate in the shutdown mode, the sterilization mode, and the heating mode cyclically alternating in step S310 or step S308, the sterilization apparatus 130 may be controlled to be preheated in the heating mode for a specified time. After that, step S310 or step S308 is performed. That is, after the sterilization apparatus 130 is started, preheating is first performed to remove at least a portion of the condensation, thereby improving the reliability of the subsequent cyclic operation of the sterilization apparatus 130.
If the cooling system is not operated for the first time after the air-cooled refrigerator 10 is powered on, the sterilization module may be turned off when the set sterilization stop condition is satisfied during the cyclic operation of the sterilization device 130 in the mode of cyclically alternating the shutdown mode, the sterilization mode and the heating mode in step S308.
The sterilization stop condition may be: the number of cycles of the sterilization apparatus 130 is counted, and if the number of cycles of the sterilization apparatus 130 reaches a target number threshold, the sterilization apparatus 130 is turned off, and the counted number of cycles is cleared to wait for the next start of the sterilization apparatus 130. Since sterilizing device 130 is activated to produce a sterilizing substance once per cycle, the number of cycles of sterilizing device 130 should be equal to the number of activations. And if the cycle times reach the target times threshold, the sterilization target of the current refrigeration cycle is indicated to be completed.
Another sterilization stop condition may be: the operation state of the cooling system of the air-cooled refrigerator 10 is detected, and if the operation state of the cooling system is off, the sterilizing device 130 is turned off. Since the blower 140 also stops operating when the refrigeration system is turned off, the sterilization device 130 is turned off following the stop of the blower 140.
The two sterilization stopping conditions may be used simultaneously, for example, after the number of cycles of the sterilization apparatus 130 reaches the target number threshold, the refrigeration system is still running (i.e. the blower 140 is still running), and the sterilization apparatus 130 is stopped at the excitation number; if the number of cycles does not reach the target number of times threshold and the refrigeration target has been completed, the refrigeration system has been shut down (i.e., the blower 140 has been shut down), the sterilization device 130 is turned off based on the signal that the refrigeration system is turned off (which may specifically be the signal that the blower 140 is turned off).
The aforementioned target number threshold may be preset or may be generated after dynamic correction. Preferably, the target number of times threshold is a target number of times threshold after the preset initial number of times threshold is corrected according to the weight of the stored articles in the storage compartment 110 such that the target number of times threshold increases as the weight of the stored articles in the storage compartment 110 increases. By adopting the target number of times threshold value dynamically corrected according to the weight of the stored articles in the storage compartment 110, it is possible to further secure a sufficient sterilization time, thereby securing a sterilization effect.
It will be appreciated by those skilled in the art that the sterilizing substance generated by the sterilizing device may have an influence on the health of the human body if it escapes from the refrigerator or acts on the human body. Therefore, in order to avoid the influence of the sterilization process on the human health, in one embodiment, the opening and closing states of the door of the storage compartment 110 are monitored during the process of starting the sterilization device 130 in the preset manner in step S310 or step S308, and the operation and closing of the sterilization device 130 is controlled according to the opening and closing states of the door of the storage compartment 110. Specifically, the open/close state of the door of the storage compartment 110 can be detected in real time; if the door of the storage compartment 110 is in an open state, the sterilization device 130 is closed until the door of the storage compartment 110 is in a closed state, and then the sterilization device 130 is started to operate in the preset mode. The operation and closing of the sterilizing device 130 are controlled by the opening and closing state of the door body associated with the storage compartment 110, so that sterilizing substances caused by the fact that the sterilizing device 130 still works when the door body is opened are prevented from directly acting on a nearby human body and escaping from the refrigerator, and the influence on the health of the human body is effectively avoided.
Accordingly, referring to fig. 2, the air-cooled refrigerator 10 may further include a door switch 160. The door switch 160 is disposed at the door of the storage compartment 110, and is connected to the controller 150 (specifically, the processor 152 of the controller 150) for detecting the open/close state of the door of the storage compartment 110. The door switch 160 may be, for example, a hall switch, a photoelectric switch, or the like, which is not particularly limited in the present application.
In addition, as mentioned above, the sterilizing substances generated by the sterilizing device 130 are propagated by the air flow driven by the blower 140, so that in order to ensure the sterilizing efficiency and effectiveness, the operation state of the blower 140 of the cooling system of the air-cooled refrigerator 10 can be monitored during the process of starting the sterilizing device 130 to operate in a preset manner in step S310 or step S308, and the operation and closing of the sterilizing device 130 can be controlled according to the operation state of the blower 140. Specifically, the operation state of the blower 140 of the refrigeration system may be detected in real time; if the operation state of the blower 140 is a stop or a malfunction, the sterilization device 130 is turned off until the sterilization device 130 is started next time. For example, if the rotational speed of the blower 140 is detected to be less than the set rotational speed threshold, the blower 140 may be deemed to be malfunctioning. Further, after detecting the fan 140 failure, a failure identifier may be returned to the controller 150, and the controller 150 controls the corresponding execution unit to alarm.
Having described various implementations of the various links of the embodiments shown in fig. 3 and fig. 4, the implementation process of the sterilization method of the air-cooled refrigerator of the present application will be described in detail by way of specific embodiments.

In step S512, the sterilization device 130 is controlled to preheat for a specified time in the heating mode, and then to cyclically operate in a cyclically alternating manner of the shutdown mode, the sterilization mode and the heating mode according to a preset cycle parameter.
Step S514, counting the cycle number of the sterilization device 130 and detecting the operation state of the refrigeration system in the cycle operation process, and if the cycle number reaches the target number threshold or the operation state of the refrigeration system is off, closing the sterilization device 130. After that, the process returns to step S502 to wait for the next start-up of the refrigeration system.
In this embodiment, the preset temperature threshold, the preset weight threshold, the preset humidity threshold, and the target frequency threshold may be set according to the actual situation and the application requirement of the sterilization device 130 and the air-cooled refrigerator 10. The cycle parameters preset in step S506 and step S512 are as described above and are not repeated.
In addition, during the cyclic operation of step S512, the open/close state of the door of the storage compartment 110 is detected in real time. If the door of the storage compartment 110 is in an open state, the sterilization device 130 is closed until the door of the storage compartment 110 is in a closed state, and then the sterilization device 130 is continuously controlled to operate in a cyclic and alternating mode of a shutdown mode, a sterilization mode and a heating mode according to preset cycle parameters. Meanwhile, during the cyclic operation of step S512, the operation state of the fan 140 of the refrigeration system is also detected in real time. If the operation state of the blower 140 is a shutdown or failure, the sterilization device 130 is turned off, and the process returns to step S502 to wait for the next start-up of the refrigeration system.
The embodiment realizes the dynamic and reasonable control of the starting of the sterilization device 130, improves the utilization efficiency of the sterilization device 130 while guaranteeing the sterilization effect, reduces the influence on the health of users, and avoids unnecessary energy consumption.
