Refrigerators are essential appliances for home life, and the popularity of the refrigerators in cities exceeds 90%. The low temperature environment in the refrigerator can also cause the food to breed harmful microorganisms, which becomes a health killer. Taking the refrigerating chamber of a refrigerator as an example, the temperature in the refrigerating chamber is generally 0-10 ℃, at which the activity of microorganisms is obviously reduced, the food spoilage speed is obviously slowed down, but specific bacteria such as psychrophile can not be killed or inhibited. It is therefore necessary to perform sterilization treatment of the refrigerator. Commonly used sterilization methods include contact sterilization and non-contact sterilization. The contact type sterilization refers to sterilization by installing a photocatalyst or a cold catalyst or adding an antibacterial agent into a refrigerator liner material, and the contact type sterilization can only kill harmful microorganisms on the surface of food which is in contact with a sterilization medium.

Since the contact sterilization has a very small sterilization effect, the non-contact sterilization is carried out at the same time, and specifically includes ultraviolet sterilization or ozone sterilization. The existing non-contact sterilization control mode mainly comprises the following steps: firstly, controlling a degerming device to degerming according to fixed start-stop time; and secondly, a sterilization control is performed by adding an ozone concentration sensor, a germ concentration sensor or an odor sensor and based on sampling data of the corresponding sensors. The inventor researches and discovers that the first mode cannot be intelligently turned on or off according to the actual use scene of a user, the intelligent degree is low, energy conservation and emission reduction are not facilitated, and the degerming effect is poor; in the second mode, the ozone concentration sensor, the germ concentration sensor and the odor sensor are all very-used sensors, so that the device cost is high, and the control of the whole machine cost is not facilitated. Based on the above, the application provides a refrigerator sterilization control method, a refrigerator sterilization control device, a computer readable storage medium, a computer program product and a refrigerator, and the sterilization effect of the refrigerator is improved on the basis of limiting the device cost by optimizing the sterilization time and the sterilization duration.

In one embodiment, as shown in fig. 1, there is provided a refrigerator sterilization control method including steps S102 to S104:

step S102: and acquiring the position information of the refrigerator door, and judging whether the door opening action exists at present according to the position information.

Wherein, be provided with the food apotheca in the refrigerator, this food apotheca keeps apart with the external world through refrigerator body and corresponding refrigerator door. Specifically, can be at each refrigerator door position respectively mounted position detection device, like proximity switch or position sensor, carry out the collection that corresponds refrigerator door position signal, obtain positional information and send to controlling means, acquire the positional information of refrigerator door by controlling means again to judge according to this positional information whether the position of corresponding refrigerator door relative refrigerator body changes, if then there is the action of opening the door at present, if there is not the action of opening the door at present. It can be understood that the change of the position of the refrigerator door relative to the refrigerator body may refer to the change of the relative position of the refrigerator door relative to the refrigerator body caused by the rotation or sliding of the refrigerator door relative to the refrigerator body.

Step S103: under the condition that there is the action of opening the door at present, the moment humidity of opening the door and the moment humidity of closing the door of the apotheca that the acquisition refrigerator door corresponds to whether the humidity of apotheca risees according to the moment humidity of opening the door and the moment humidity of closing the door judgement apotheca.

As mentioned above, the storage chamber corresponding to the refrigerator door refers to a storage chamber communicating with the outside through the refrigerator door. Under the current condition that has the action of opening the door, the switch of refrigerator door can make the inside and outside air convection of refrigerator, not only can cause the harmful microorganism exchange in the air to lead to the refrigerator in harmful microorganism to increase, can cause humidity rising in the refrigerator moreover to cause harmful microorganism reproductive capacity reinforcing, on this basis, under the prerequisite of confirming the current action of opening the door, judges whether the action of opening the door has aroused the rising of apotheca humidity.

Further, the condition for determining whether the humidity of the storage chamber is increased is not unique, and the humidity increase of the storage chamber may reach a preset increase, or the humidity of the storage chamber may be increased when the humidity is greater than the humidity at the time of opening the door.

Specifically, can dispose humidity detection device and carry out humidity to the apotheca and gather, at the moment of opening the door and the moment of closing the door, trigger humidity detection device because of refrigerator door position change and carry out humidity and gather, obtain the moment humidity of opening the door and the moment humidity of closing the door that correspond the apotheca to send to controlling means, judge whether the humidity of apotheca risees according to this moment humidity of closing the door and the moment humidity of opening the door by controlling means again. If not, it indicates that the humidity in the storage chamber is not increased due to the door opening operation (for example, under the condition of short door opening time or low environmental humidity), the current sterilization requirement is not urgent, and at this time, the sterilization is not performed, but the step S102 is returned to continue to monitor the position information of the refrigerator door.

If so, it is indicated that the humidity in the storage chamber is increased due to the door opening action, the harmful microorganisms in the refrigerator are increased, the reproductive capacity of the harmful microorganisms is enhanced, and the current sterilization requirement is urgent, and at this time, the step S104 is executed: and calculating the door opening time according to the door opening time and the door closing time of the storage chamber, determining a first sterilization time according to the door opening time, and outputting a first sterilization instruction.

Wherein, first degerming instruction is used for instructing degerming device continuous operation first degerming duration, carries out degerming work. The door opening duration refers to the time difference between the door opening time and the door closing time. It can be understood that the longer the door is opened, the stronger the convection of air inside and outside the refrigerator caused by the door opening action is, the more harmful microorganisms are brought in, and the longer the required sterilization time is on the premise of certain sterilization intensity.

Specifically, the timing device is configured to time the door opening starting time and the door opening ending time, the timing information is sent to the control device, the control device calculates the door opening duration according to the timing information, the first degerming duration is determined based on the obtained door opening duration, a corresponding first degerming instruction is output to the degerming device, and the degerming device is instructed to degerming. Further, the manner in which the control device determines the first sterilization duration according to the door opening duration is not exclusive. For example, the first sterilization duration may be determined according to the door opening duration and the corresponding relationship between the preset door opening duration and the first sterilization duration; the first sterilization duration can also be comprehensively determined according to the door opening duration and the difference value between the door opening time humidity and the door closing time humidity caused by door opening.

In one embodiment, as shown in fig. 2, the first degerming duration is determined according to the door opening duration, which includes steps S201 to S203.

Step S201: and judging whether the difference value between the door opening time and the preset door opening time is less than or equal to a set difference value.

The preset door opening time can be fixed or can be changed in real time according to the environmental humidity, for example, the preset door opening time can be changed along with the environmental humidity in equal proportion. Further, the magnitude of the preset difference is not unique, and may be 1s, 2s, or 5s, for example. In one embodiment, the preset difference is zero, that is, step S201 is: and judging whether the door opening time is equal to the preset door opening time.

Specifically, after the control device calculates the door opening time, the control device compares the door opening time with the current preset door opening time, and judges whether the difference between the door opening time and the preset door opening time is smaller than or equal to a set difference.

When the difference between the door opening time and the preset door opening time is less than or equal to the set difference, executing step S202: and determining the preset degerming duration corresponding to the preset door opening duration as a first degerming duration. Wherein, the preset degerming duration can be set according to degerming effect statistical data in the historical degerming experimental process. Specifically, the corresponding relation between the preset door opening time and the preset degerming time can be established according to historical degerming effect statistical data, and when the difference between the actual door opening time and the current preset door opening time is smaller than or equal to a set difference, the preset degerming time corresponding to the preset door opening time is determined as the first degerming time.

If the difference between the door opening time and the preset door opening time is greater than the set difference, step S203 is executed: and calculating to obtain a time ratio of the door opening time to the preset door opening time, and determining the first degerming time by combining the time ratio and the preset degerming time corresponding to the preset door opening time.

Specifically, the control device calculates a time ratio of the door opening duration to the preset door opening duration according to the door opening duration and the current preset door opening duration, and multiplies the time ratio by the preset degerming duration corresponding to the preset door opening duration to obtain the first degerming duration.

Further, in another embodiment, after the time ratio between the door opening time and the preset door opening time is obtained, the product of the time ratio and the corresponding preset sterilizing time may be multiplied by a preset coefficient to obtain the first sterilizing time. Wherein, the preset coefficient can be set according to the degerming effect statistical data in the historical degerming experimentation.

The specific determination process of the first sterilization duration is provided, the method is simple, and the working efficiency of the sterilization control process of the refrigerator is improved.

It can be understood that the refrigerator may include a plurality of storage chambers and corresponding refrigerator doors, such as a freezing chamber, a temperature-changing storage chamber, a refrigerating chamber, etc., and the refrigerator may perform door opening determination and humidity detection on the storage chambers respectively, and perform sterilization control on the storage chambers respectively according to the door opening determination and humidity detection results. Since the temperature of the refrigerating chamber in each storage chamber is relatively high, the propagation of harmful microorganisms is more facilitated, and for the convenience of understanding, the storage chamber is taken as the refrigerating chamber in the following description.

It should be noted that, if the door opening action occurs again in the sterilization process, the sterilization is stopped during the door opening, the unfinished sterilization duration of this time and the first sterilization duration corresponding to the next door opening action are superimposed to obtain an updated first sterilization duration, and then the first sterilization instruction is output based on the updated first sterilization duration.

According to the refrigerator sterilization control method, on one hand, the situation that the air inside and outside the refrigerator is convected due to opening and closing of the refrigerator door is considered, harmful microorganisms in the air are exchanged to increase the harmful microorganisms in the refrigerator, and the humidity in the refrigerator is possibly increased to enhance the reproductive capacity of the harmful microorganisms, so that the position information of the refrigerator door is obtained firstly, whether door opening action exists at present or not is judged according to the position information, and a sterilization instruction is output only under the condition that the door opening action exists and the humidity of a corresponding storage chamber is increased due to the door opening action; on the other hand, the strength of air convection caused by the opening and closing of the refrigerator door is directly related to the door opening time, the first sterilization time is determined according to the door opening time, which is equivalent to performing sterilization control differently according to the current actual scene, and the matching degree of the sterilization time and the actual scene is favorably improved. The sterilization control process optimizes the sterilization opportunity and the sterilization duration, and is favorable for improving the sterilization effect of the refrigerator. In addition, the first sterilization duration is determined according to the door opening duration, and a first sterilization instruction is output, which means that the sterilization device is opened after the refrigerator door is closed, so that the health hidden danger brought to a user by sterilization during door opening can be avoided, and the safety of the sterilization process can be improved; and the hardware devices used for humidity detection, position detection and timing are conventional devices, the device cost is low, and the cost can be controlled while the refrigerator sterilization effect is improved.

As described above, the increase in the humidity in the storage chamber may cause the increase in the ability of harmful microorganisms to multiply, and the increase in the humidity in the storage chamber may be caused by not only the door opening operation, but also the defrosting operation. Based on this, in one embodiment, as shown in fig. 3, after step S102, step S105 and step S106 are further included.

Step S105: and under the condition that no door opening action exists at present, acquiring the humidity of the storage chamber of the refrigerator, and judging whether the humidity reaches a preset humidity threshold value.

Specifically, under the condition that no door opening action exists at present, the humidity detection device continuously detects the humidity of the storage chamber, the control device acquires the humidity of the storage chamber, and whether the humidity reaches a preset humidity threshold value is judged. If not, the current sterilization requirement is not urgent, and at the moment, sterilization is not carried out.

If yes, it indicates that the sterilization requirement is urgent, go to step S106: and outputting a second sterilization instruction.

The second degerming instruction is used for instructing the degerming device to perform degerming operation according to the degerming mode corresponding to the second degerming instruction. This degerming mode is long including degerming intensity and degerming, specifically can set up according to degerming effect statistics in the historical degerming experimentation.

Furthermore, different preset humidity thresholds can be set for different storage chambers respectively based on the characteristics of common microorganisms in the storage chambers, and differential sterilization control is performed based on the relation between the humidity of the storage chamber detected in real time and the corresponding preset humidity threshold.

When the door opening operation occurs during the sterilization operation by the sterilization apparatus based on the second sterilization command, the present sterilization is stopped, the first sterilization duration is determined based on steps S102 to S104, the first sterilization command is output, and the corresponding sterilization control is performed.

Above-mentioned embodiment, do not have the condition of opening the door action at present, acquire the humidity of refrigerator apotheca to under this humidity reaches the prerequisite of presetting the humidity threshold value, output second degerming instruction, control bacteria removing device carries out degerming work, can in time carry out the degerming under the condition that refrigerator apotheca humidity too high can arouse harmful microorganism reproductive capacity reinforcing, restrain harmful microorganism's reproduction, be favorable to further promoting the degerming effect of refrigerator.

In an embodiment, with continuing reference to fig. 3, before step S102, step S101 is further included: and detecting whether a preset forced sterilization condition is triggered.

The forced sterilization condition may be that the refrigerator is powered on, or that a preset forced sterilization time is reached, or that a forced sterilization instruction sent by a user is received. It will be appreciated that the forced sterilization time can be set by the user as desired. For example, the forced sterilization time may be a certain fixed time per week, or a certain fixed time per month. Further, the way of sending the forced sterilization instruction by the user is not unique, for example, a forced sterilization button may be arranged on the refrigerator, and the forced sterilization instruction is sent when the user touches or presses the button; the user may send a forced sterilization instruction to the control apparatus through the terminal.

Specifically, the control device detects whether a forced sterilization condition is triggered currently, and if not, the step S102 is executed; if yes, go to step S107: and controlling the degerming device to perform forced degerming work.

If the forced sterilization condition is triggered, the sterilization operation is required to be executed even if the door opening action does not exist at present or the humidity is not too high, and at the moment, the control device controls the sterilization device to perform the forced sterilization operation based on the forced sterilization mode.

In the embodiment, the forced sterilization mode is added on the basis of the existing sterilization starting judgment condition, and can be started as required, so that the flexibility of the refrigerator sterilization control method is enhanced.

In one embodiment, step S107 includes: and controlling the degerming device to continuously work for a second degerming time, and then intermittently working at a preset period.

The second sterilization duration can be determined according to the volume of the storage chamber of the refrigerator, and the larger the volume is, the longer the corresponding second sterilization duration is. Further, the intermittent operation at the preset period means that the sterilizing device is not operated continuously, for example, the operation time b1 is followed by the rest time b2, or the rest time b3 is followed by the operation time b4 is followed by the rest time b 5. Wherein, the sum of b1 and b2, and the sum of b3, b4 and b5 are equal to the preset period.

In addition, in order to ensure the thoroughness of sterilization, the sterilization device can be controlled to continuously operate in an intermittent working state; or after the intermittent work reaches the set period, controlling the degerming device to exit the forced degerming mode, stopping the forced degerming work, and returning to the step of detecting whether to trigger the preset forced degerming condition so as to save energy.

It should be noted that if door opening occurs during the continuous operation of the degerming device for performing forced degerming, degerming is suspended during the door opening period, after the door is closed, the degerming device continues to perform forced degerming until the cumulative degerming operation time reaches the second degerming duration, and then performs subsequent intermittent degerming operation; and if the door is opened during the forced sterilization process of the intermittent operation of the sterilization device, exiting the forced sterilization mode, determining the first sterilization duration based on the steps S102 to S104, outputting a first sterilization instruction, and performing corresponding sterilization control.

Above-mentioned embodiment, force under the degerming mode, it is long when the first continuous operation second degerming of control bacteria removing device, can ensure the degerming effect, the bacteria removing device is in order to predetermine cycle intermittent type work again, be equivalent to open and close with certain start-stop ratio periodicity, can avoid because the long-time degerming device life-span that the work of continuing to bring of bacteria removing device shortens and the ageing problem of material in the refrigerator, be favorable to promoting the life of refrigerator, simultaneously can also avoid to a certain extent because the too long ozone flavor that brings of bacteria removing device continuous operation time is too thick problem.

In one embodiment, the intermittent operation with a preset period comprises: running the third degerming time and stopping running for setting the rest time in each period; as shown in fig. 4, in the process of setting the rest period when the sterilizing apparatus is stopped, the refrigerator sterilizing control method further includes step S401 and step S402.

Step S401: and acquiring the temperature and the humidity of the storage chamber of the refrigerator, and judging whether the secondary sterilization starting condition is met or not according to the temperature and the humidity.

And the sum of the third degerming time and the set rest time is equal to the time of the preset period. The third sterilization duration and the set rest duration can be set correspondingly according to the specific model of the refrigerator and the historical sterilization effect statistical data of the corresponding model. Specifically, in the process that the sterilizing device stops running and the rest time length is set, the temperature detection device and the humidity detection device respectively detect the temperature and the humidity of the refrigerator storage chamber in real time, and corresponding temperature sampling data and corresponding humidity sampling data are obtained and sent to the control device. And judging whether the secondary sterilization starting condition is met or not by the control device according to the temperature sampling data and the humidity sampling data. Further, the secondary sterilization start condition specifically includes a temperature condition and a humidity condition. The temperature condition can be that the temperature of the storage chamber of the refrigerator reaches a set temperature threshold value, and/or the temperature rise of the temperature of the storage chamber of the refrigerator relative to the temperature at the previous moment is larger than a preset temperature rise; the humidity condition may be that the humidity of the storage chamber of the refrigerator reaches a set humidity threshold, and/or that the humidity of the storage chamber of the refrigerator is increased by more than a preset humidity increase amount relative to the humidity at the previous time. If not, the degerming device continues to stop running until the stop running time reaches the set rest time.

If yes, go to step S402: and determining the fourth sterilization duration based on the humidity of the storage chamber of the refrigerator, and outputting a secondary sterilization instruction.

Specifically, if the secondary sterilization start condition is reached, the sterilization device needs to be controlled to continuously start the fourth sterilization duration to perform the secondary sterilization operation. The sterilization period at this time, i.e., the fourth sterilization period, is determined by the control device based on the humidity of the storage chamber of the refrigerator. It should be noted that, in order to simplify the control process, the set humidity threshold and the preset humidity threshold may be set to the same value.

Further, the specific manner in which the control device determines the fourth sterilization period based on the humidity of the storage chamber of the refrigerator is not exclusive.

In one embodiment, the control device determines the fourth sterilization duration according to the humidity of the storage chamber of the refrigerator and the preset corresponding relationship between the humidity of the storage chamber and the sterilization duration.

In another embodiment, the secondary sterilization starting condition comprises that the temperature of the storage chamber of the refrigerator reaches a set temperature threshold value, and the humidity of the storage chamber of the refrigerator is increased by a value greater than a preset humidity increase amount relative to the humidity at the previous moment; determining a fourth sterilization duration based on the humidity of the refrigerator storage chamber, comprising: and calculating the ratio of the humidity increase value of the refrigerator storage chamber to the humidity increase value at the previous moment, and determining the fourth sterilization duration according to the ratio and the set sterilization duration corresponding to the set humidity increase value.

As described above, the humidity detecting device detects the humidity of the storage chamber of the refrigerator in real time during the set rest period when the sterilizing device is stopped. The humidity of the storage chamber of the refrigerator is increased relative to the humidity at the previous moment, namely the humidity acquired by the humidity detection device at present is increased relative to the humidity acquired by the last sampling. Further, the set humidity increase amount may be fixed or may be changed in real time according to the humidity of the storage chamber, for example, the set humidity increase amount is smaller as the current humidity of the storage chamber is higher. In addition, the corresponding relation between the set humidity increase amount and the set sterilization duration can be set according to historical sterilization effect statistical data.

Specifically, the control device obtains humidity sampling data obtained by real-time detection of the humidity detection device, calculates an increase value of the humidity of the refrigerator storage chamber relative to the humidity at the previous moment and a current set humidity increase amount according to the humidity sampling data, calculates a ratio of the increase value to the set humidity increase amount, multiplies the ratio by the set sterilization duration corresponding to the set humidity increase amount to obtain a fourth sterilization duration, and outputs a corresponding sterilization instruction.

Further, in another embodiment, after the ratio of the current increase value to the set humidity increase value is obtained, the fourth sterilization duration may be obtained by multiplying the product of the ratio and the corresponding set sterilization duration by the set coefficient. Wherein, the set coefficient can be set according to degerming effect statistical data among the historical degerming experimentation.

The fourth sterilization duration determination process is provided, the method is simple, and the working efficiency of the refrigerator sterilization control process is improved.

It will be appreciated that the set sterilization duration is necessarily less than the set rest duration, and likewise, the fourth sterilization duration is necessarily less than or equal to the rest of the set rest duration for the current cycle. And if the calculated fourth degerming duration is greater than the rest duration remained in the current period, setting the rest duration remained in the current period as the fourth degerming duration.

In the above embodiment, in the process that the sterilizing device stops running and the rest time duration is set, the judgment of the secondary sterilizing starting condition is introduced, the working state of the sterilizing device can be adjusted in time according to the actual situation, and the sterilizing effect of the refrigerator is further improved.

For the sake of understanding, the specific procedures of the refrigerator sterilization control method will be described in detail below with reference to specific embodiments. As shown in fig. 5, the method specifically comprises the following steps:

step 1: the refrigerator is powered on and opened.

Step 2: and (4) detecting whether a forced sterilization condition is triggered, if so, executing the step (3), and otherwise, executing the step (4).

And step 3: controlling the degerming device to continuously operate for a time period of t1, quitting the continuous operation after a time period of t1, taking the time period of t2 as a period, controlling the degerming device to stop operating for a time period of t4 every time period of t3, wherein t2 is t3+ t4, circulating the operation,

further, in order to ensure the thoroughness of sterilization, the sterilization device can be controlled to continuously operate in an intermittent working state by taking the time length of t2 as a period; as shown in fig. 5, after the intermittent operation reaches the set period, the sterilization apparatus may be controlled to exit the forced sterilization mode, stop the forced sterilization operation, and return to step 2 to save energy.

If the door opening action is met within the time length of t1, the degerming is suspended during the door opening period, after the door is closed, the degerming device is controlled to continue degerming, and the degerming device stops working until the accumulated degerming working time reaches the time length of t 1. If the door opening action is met in the period of the time length of t2, exiting the forced sterilization mode and executing the step 4. It can be understood that if the door opening action is met in the period of the time length t3, the degerming time before the time length t3 is cleared.

In the period of the time length of t4, the temperature detection device and the humidity detection device respectively detect the temperature and the humidity of the storage chamber of the refrigerator in real time, obtain corresponding temperature sampling data and humidity sampling data and send the corresponding temperature sampling data and humidity sampling data to the control device. The control device judges whether the temperature Tn at the current moment reaches a set temperature threshold value T or not according to the temperature sampling data and the humidity sampling data₀(ii) a On the other hand, the current-time humidity Rn and the previous-time humidity Rn-1 are subjected to difference calculation, and the obtained difference value is compared with a preset humidity increase amount delta R. When Tn is more than or equal to T₀And Rn-Rn-1 >. DELTA R, controlling the degerming device to continuously operate for t5 time length to perform secondary degerming operation. Wherein t5 is a2 t6, wherein t6 is the corresponding set sterilization duration when the humidity changes to the set humidity increase Δ R1, and a2 is the ratio of the humidity increase of the refrigerator storage chamber relative to the humidity increase at the previous moment to the set humidity increase, i.e. a2 is (Rn-1)/[ Δ R1.

And 4, step 4: acquiring the position information of the refrigerator door, judging whether door opening action exists or not according to the position information, and if so, executing a step 5; if not, executing step 6.

And 5: the position detection device feeds back a door opening action signal to the control device, the timing device starts timing at the same time, timing information is fed back to the control device, and the humidity detection device collects humidity R1 at the door opening time and humidity R2 at the door closing time and feeds back the humidity to the control device. The control device judges whether the humidity of the storage chamber is increased or not according to R1 and R2, when R2 is larger than R1, the door opening time t is calculated according to timing information, the degerming time t7 is determined according to the door opening time t, the degerming device is controlled to continuously work for t7 time to perform degerming work, and after the degerming is completed, the step 2 is returned.

Wherein, determining the degerming duration t7 according to the door opening duration t includes:

when the door opening time is t-t 8, setting the degerming time t7 as a preset degerming time t1 'corresponding to the preset door opening time t8, that is, t 7-t 1';

when the door opening time is t ≠ t8, the time ratio n between the door opening time t and the preset door opening time t8 is calculated, the degerming time t7 is determined by combining the time ratio n and the preset degerming time t1 'corresponding to the preset door opening time t8, namely t7 ═ t 1' × n a1, n ═ t/t8, and a1 is a preset coefficient, and the degerming time can be set according to degerming effect statistical data in the historical degerming experimental process.

Step 6: under the condition that no door opening action exists at present, the humidity of the storage chamber of the refrigerator is obtained, and whether the humidity reaches a preset humidity threshold value R or not is judged₀And if so, controlling the degerming device to perform degerming work according to a preset degerming mode, returning to the step 2 after degerming is finished, and if not, directly returning to the step 2. When the door opening operation is performed during the sterilization in step 6, the current sterilization operation is stopped, and the operation of the sterilization apparatus is controlled according to the rule of step 5.

According to the refrigerator sterilization control method, on one hand, the situation that the air inside and outside the refrigerator is convected due to opening and closing of the refrigerator door is considered, harmful microorganisms in the air are exchanged to increase the harmful microorganisms in the refrigerator, and the humidity in the refrigerator is possibly increased to enhance the reproductive capacity of the harmful microorganisms, so that the position information of the refrigerator door is obtained firstly, whether door opening action exists at present or not is judged according to the position information, and a sterilization instruction is output only under the condition that the door opening action exists and the humidity of a corresponding storage chamber is increased due to the door opening action; on the other hand, the strength of air convection caused by the opening and closing of the refrigerator door is directly related to the door opening time, the first sterilization time is determined according to the door opening time, which is equivalent to performing sterilization control differently according to the current actual scene, and the matching degree of the sterilization time and the actual scene is favorably improved. The sterilization control process optimizes the sterilization opportunity and the sterilization duration, and is favorable for improving the sterilization effect of the refrigerator. In addition, the first sterilization duration is determined according to the door opening duration, and a first sterilization instruction is output, which means that the sterilization device is opened after the refrigerator door is closed, so that the health hidden danger brought to a user by sterilization during door opening can be avoided, and the safety of the sterilization process can be improved; and the hardware devices used for temperature detection, humidity detection, position detection and timing are conventional devices, the device cost is low, and the cost can be controlled while the refrigerator sterilization effect is improved.

Further, under the compulsory degerming mode, it is long that control bacteria removing device continuous operation t1 is earlier, can ensure the degerming effect, it uses time long as cycle intermittent type work with t2 to control bacteria removing device again, be equivalent to with the periodic opening of certain start-stop ratio and close, can avoid because the long-time degerming device life-span that continuous operation of bacteria removing device brought shortens and the ageing problem of material in the refrigerator, be favorable to promoting the life of refrigerator, simultaneously can also avoid to a certain extent because the too long ozone flavor that brings of bacteria removing device continuous operation time problem excessively. In addition, in the process that the sterilizing device stops running and the rest time is set, the judgment of the secondary sterilizing starting condition is introduced, the working state of the sterilizing device can be adjusted in time according to the actual situation, and the sterilizing effect of the refrigerator is further improved.
