These terms are only used to distinguish these description objects from each other. For example, the first threshold may be referred to as the second threshold, and similarly, the second threshold may also be referred to as the first threshold, which does not deviate from the protection scope of the present application.

The first embodiment of the present invention provides a control method for replacing the sterilization and deodorization device of a refrigerator. Here, a control device may be provided in the refrigerator, and the control device executes the control method for replacing the sterilization and deodorization device. Here, the control device can use the power supply provided by the refrigerator (it can be understood that when the refrigerator is powered off, the control device will be powered off), and can also use an independent power source (for example, a rechargeable battery, etc.) for the The control device provides power (it can be understood that the control device can still continue to work after the refrigerator is powered off); as shown in Figure 1, it includes the following steps:

Step 101: Control the sterilization and deodorization device to process the storage compartment, and during this processing, obtain the state information of the sterilization and deodorization device and/or the state information of the storage compartment; here, the sterilization and deodorization device may It is installed in the storage compartment of the refrigerator (for example, a refrigerating room, a freezing room, or a greenhouse, etc.). In practice, the sterilization and deodorization device may be activated at regular intervals, that is, it will receive an instruction to start sterilization and deodorization at regular intervals, and then control the sterilization and deodorization device to start the process of sterilization and removal of odorous gases. Here, it can be understood that the sterilization and deodorization device has a sterilization module and a deodorization module, the sterilization module can kill bacteria in the storage compartment, and the deodorization module can remove peculiar smell gas in the storage compartment.

Here, the odorous gas may be ammonia, methylamine, dimethylamine, trimethylamine, ethylamine, diisopropylamine, pyrimidine, hydrogen sulfide, sulfur dioxide, or dimethylsulfide.

Here, a sensor can be provided in the sterilization and deodorization device, and the sensor can be used to obtain the status information of the sterilization and deodorization device; a sensor can be provided in the storage compartment, and the sensor can obtain the status information of the storage compartment.

Step 102: Determine whether the status information of the sterilization and deodorization device meets a first preset condition and/or determine whether the status information of the storage compartment meets a second preset condition;

Here, it can be understood that when the sterilization and deodorization device has passed the expiration date, the "sterilization" or "deodorization" capability of the sterilization and deodorization device will definitely decrease. For example, after the expiration date, the sterilization function will decrease. At this time, the status information can include several status values that can characterize the "sterilization ability"; after the expiration date, the deodorization function will definitely decline. At this time, the status information can include several status values that can characterize the "deodorization ability". Status value. Therefore, in this step, when it is determined based on the status information of the sterilization and deodorization device that the capabilities of the sterilization and deodorization device (for example, sterilization ability, deodorization ability) have fallen to a certain threshold (that is, the first preset Condition), and/or when it is determined based on the state information of the storage compartment that the capabilities of the sterilization and deodorization device (for example, sterilization capability, deodorization capability) have fallen to a certain threshold (that is, the second preset condition is satisfied It can be concluded that the sterilization and deodorization device has passed the expiration date, and the user needs to be reminded to replace the sterilization and deodorization device.

Step 103: If yes, push a reminder to replace the sterilization and deodorization device.

Here, in step 102, the judgment condition may be:

(1) The judgment condition is "judge whether the status information of the sterilization and deodorization device meets the first preset condition", at this time, as long as the status information of the sterilization and deodorization device meets the first preset condition, the judgment result is yes ；

(3) The judgment condition is "judge whether the state information of the sterilization and deodorization device meets the first preset condition and judge whether the state information of the storage compartment meets the second preset condition", at this time, only sterilization and deodorization When the state information of the device meets the first preset condition and the state information of the storage compartment meets the second preset condition, the judgment result is yes.

Here, the way of pushing the reminder of replacing the sterilization and deodorizing device may be: display the reminder on the display screen, broadcast the reminder by voice, and send the reminder to the user's mobile phone in the form of short messages.

In the embodiment of the present invention, the "acquiring the status information of the sterilization and deodorization device and/or the status information of the storage compartment" specifically includes: obtaining the concentration change value of the peculiar smell gas in the storage compartment; wherein, when the When the concentration change value is a positive number, the concentration of the peculiar smell gas increases; when the concentration change value is a negative number, the concentration of the peculiar smell gas decreases; here, a function of the sterilization and deodorization device is to remove the storage compartment The odor gas in the air can work according to the actual situation. For example: (1) In an air-cooled refrigerator, the sterilization and deodorization device can be installed at the air inlet or the return air outlet. When cooling, the air will flow Through the sterilization and deodorization device, the sterilization and deodorization device can remove the peculiar smell gas in the air. When the refrigeration system is working, the sterilization and deodorization device is also working; (2) The sterilization and deodorization device can be installed in the storage compartment Device, the sterilization and deodorization device may be provided with a fan, when the sterilization and deodorization device is working, the fan will rotate, so that the air in the storage compartment will flow through the sterilization and deodorization device, and then the sterilization and deodorization device Will filter the odorous gas in the air.

Here, during the working process of the sterilization and deodorization device, the concentration value of the odor gas can be detected at regular intervals (the concentration value can be the concentration value of any odor gas, or the sum of the concentration values of all odor gases ), so that the concentration change value of the odorous gas can be obtained.

Here, odor gas sensors can be installed in the storage compartment. These sensors measure the concentration change value of odor gas. They can be divided into: (1) stacked semiconductor type, which uses some metal oxide semiconductor materials at a certain temperature Under the principle that the electrical conductivity changes with the change of the environmental gas composition, it can be effectively used for methane, ethane, propane, butane, alcohol, formaldehyde, carbon monoxide, carbon dioxide, ethylene, acetylene, vinyl chloride, benzene Measurement of the concentration of ethylene, acrylic acid and other gases; (2) Combustion type, a high-temperature resistant catalyst layer is prepared on the surface of the platinum resistor. At a certain temperature, the combustible gas is catalytically burned on the surface, and the combustion makes the temperature of the platinum resistor increase , The resistance changes, and the change value is a function of the concentration of flammable gas; (3) Thermal conductivity pool type, each gas has its own specific thermal conductivity, when the thermal conductivity of two or more gases is quite different At the time, the thermal conductivity element can be used to distinguish the content of one of the components, which can be used for the concentration detection of hydrogen, carbon dioxide, and high-concentration methane; (3) Electrochemical method, a considerable part of flammable, toxic and harmful gases are electrochemical Activity can be electrochemically oxidized or reduced, etc.

The "determining whether the state information of the storage compartment satisfies the second preset condition" specifically includes: determining whether the concentration change value is greater than a first threshold; the first threshold is less than zero. Here, it can be understood that if the sterilization and deodorization device is within the validity period, the concentration of the peculiar smell gas should decrease relatively quickly (that is, it needs to be less than or equal to the first threshold), and if the concentration change value is greater than the first When the threshold value (especially when the concentration change value is greater than zero), it means that the function of the sterilization and deodorization device has failed. At this time, the user needs to be notified to replace the sterilization and deodorization device.

In the embodiment of the present invention, the "acquiring the status information of the sterilization and deodorization device or the status information of the storage compartment" specifically includes: obtaining the concentration change value of the effective ingredient in the storage compartment; wherein, when the concentration changes When the value is positive, the concentration of the effective ingredient increases; when the change in concentration is negative, the concentration of the effective ingredient is decreasing; the effective ingredient is a sterilization factor or deodorization factor; here, sterilization and deodorization The device can release some effective ingredients into the storage compartment. These effective ingredients can be used to sterilize or remove odorous gases, for example: release ozone, which can be used to kill bacteria; release CLO2, CLO2 can be used to remove odorous gases, etc. .

Here, in the working process of the sterilization and deodorization device, the concentration value of the effective ingredient can be checked at regular intervals (the concentration value can be the concentration value of any effective ingredient, or the sum of the concentration values of all effective ingredients ), so that the concentration change value of the effective ingredient can be obtained.

The "determining whether the state information of the storage compartment meets a second preset condition" specifically includes: determining whether the concentration change value is less than a second threshold; the second threshold is less than or equal to zero. Here, it can be understood that during the processing of the sterilization and deodorization device, the sterilization and deodorization device will continuously release these effective ingredients into the storage compartment, and these effective ingredients will also be continuously consumed, but the effective The concentration of the component should not drop quickly (that is, it needs to be greater than or equal to the second threshold). Therefore, when the concentration change of the active component is less than the second threshold, it can be confirmed that the sterilization and deodorization device has passed the expiration date.

In the embodiment of the present invention, the "controlling the sterilization and deodorization device to process the storage compartment" specifically includes: controlling the sterilization and deodorization device to emit ultraviolet rays into the storage compartment; here, the ultraviolet rays have the best wavelength in the range of 240nm to 280nm The bactericidal effect, which can destroy the molecular structure of DNA (Deoxyribonucleic Acid) or RNA (Ribonucleic Acid) in bacterial viruses, causing the death of growth cells and/or the death of regenerative cells, achieving the effect of sterilization , Especially when the wavelength is 253.7nm, ultraviolet rays have the strongest bactericidal effect.

In addition, if the photocatalyst (a general term for a photo-semiconductor material with photocatalytic function represented by nano-sized titanium dioxide) is coated on the surface of the substrate, it will produce a strong catalytic degradation function under the action of ultraviolet light and visible light, which can effectively It degrades toxic and harmful gases in the air effectively, can effectively kill a variety of bacteria, and can decompose and harmlessly treat the toxins released by bacteria or fungi. It also has the functions of formaldehyde removal, deodorization, anti-pollution and air purification.

The “acquiring the status information of the sterilization and deodorization device and/or the status information of the storage compartment” specifically includes: obtaining the intensity value of the ultraviolet rays in the storage compartment; the “determining whether the status information of the storage compartment is Satisfying the second preset condition" specifically includes: judging whether the intensity value of the ultraviolet rays is less than the third threshold value. In practice, in order to improve the sterilization effect of ultraviolet rays, the intensity value of ultraviolet rays needs to be greater than a certain value, for example, needs to be greater. Here, the principle of measuring the intensity value of ultraviolet light can be as follows: ordinary silicon photovoltaic cells do not respond to ultraviolet light, while fluorescent ultraviolet silicon photovoltaic cells can respond well to ultraviolet light. The two types of photovoltaic cells take light at the same time, and through the operation of the two signals If it is poor, the ultraviolet signal in the measured light can be obtained.

In the embodiment of the present invention, the bactericidal factor is anion. Here, negative ions can destroy the molecular protein structure of microorganisms such as bacteria and viruses, causing structural changes or energy transfer, thereby causing the death of bacteria, viruses and other microorganisms, so that the storage compartment can be sterilized.

Here, the following methods can be used to measure the concentration of negative ions: light scattering method, filter weighing method, oscillatory balance measurement method, and β-ray measurement method. Here, during the working process of the sterilization and deodorization device, the concentration value of the negative ion can be detected at regular intervals, so that the concentration change value of the negative ion can be obtained.

Here, it can be understood that during the processing of the sterilization and deodorization device, the sterilization and deodorization device will continuously release negative ions into the storage compartment, and the negative ions will also be continuously consumed, but the concentration of the negative ions should not be The decline is very fast (that is, it needs to be greater than or equal to the fourth threshold). Therefore, when the negative ion concentration change value is less than the fourth threshold, it can be confirmed that the sterilization and deodorization device has passed the expiration date.

Optionally, the "acquiring status information of the sterilization and deodorization device" specifically includes: acquiring the weight or content of a certain component in the sterilization and deodorization module, for example: the sterilization and deodorization device has a slow-release essential oil The diffusion module has a weight sensor below. When the essential oil is slowly released, the weight becomes zero. Therefore, the status information of the sterilization and deodorization device may include: the weight of the essential oil sustained release diffusion module; Whether the status information of the device meets the first preset condition" specifically includes: when the weight of a certain component is less than the first threshold or the content is less than the second threshold, the first preset condition is met, for example: if the essential oil slow-release diffusion module If the weight is zero, the first preset condition is satisfied.

For example, after the expiration date, the sterilization function will decline. At this time, the status information can be Including several state values that can characterize the "sterilization ability"; after the expiration date, the deodorizing function will definitely decline. At this time, the state information can include several state values that can characterize the "odor removal ability". Therefore, in this module, when it is determined based on the status information of the sterilization and deodorization device that these capabilities (for example, sterilization ability, deodorization ability) of the sterilization and deodorization device have fallen to a certain threshold (that is, the first preset is satisfied Condition), and/or when it is determined based on the state information of the storage compartment that the capabilities of the sterilization and deodorization device (for example, sterilization capability, deodorization capability) have fallen to a certain threshold (that is, the second preset condition is satisfied It can be concluded that the sterilization and deodorization device has passed the expiration date, and the user needs to be reminded to replace the sterilization and deodorization device.
