For example, the first threshold value may be referred to as the second threshold value, and similarly the second threshold value may also be referred to as the first threshold value, without departing from the scope of the present application.
The embodiment of the invention provides a method for replacing, managing and controlling a sterilization and odor removal device of a refrigerator, wherein a control device can be arranged in the refrigerator, and the control device executes the method for replacing, managing and controlling the sterilization and odor removal device. Here, the control device may use a power supply provided by the refrigerator (it is understood that the control device is powered off when the refrigerator is powered off), and may also use a separate power supply (e.g., a rechargeable battery, etc.) to supply power to the control device (it is understood that the control device may still continue to operate when the refrigerator is powered off); as shown in fig. 1, the method comprises the following steps:
step 101: controlling the sterilization and deodorization device to process the storage chamber, and acquiring state information of the sterilization and deodorization device and/or state information of the storage chamber in the processing process; here, the sterilizing and deodorizing device may be provided in a storage compartment (e.g., a refrigerating compartment, a freezing compartment, a temperature-changing compartment, etc.) of the refrigerator. In practice, the sterilization and odor removal device may be activated at intervals, that is, an instruction for activating the sterilization and odor removal device is received at intervals, and then the sterilization and odor removal device is controlled to start sterilization and odor removal. Here, it is understood that the sterilizing and deodorizing device has a sterilizing module capable of sterilizing bacteria in the storage compartment and a deodorizing module capable of removing odor gas from the storage compartment.
Here, the odor gas may be: ammonia, methylamine, dimethylamine, trimethylamine, ethylamine, diisopropylamine, pyrimidine, hydrogen sulfide, sulfur dioxide or dimethyl sulfide and the like.
Here, the sterilization and odor removal device may be provided with a sensor, and the sensor may be used to obtain status information of the sterilization and odor removal device; a sensor may be provided in the storage compartment, which may acquire status information of the storage compartment.
Step 102: judging whether the state information of the sterilizing and deodorizing device meets a first preset condition and/or judging whether the state information of the storage chamber meets a second preset condition;
here, it is understood that when the sterilizing and deodorizing device has passed its effective period, the sterilizing or deodorizing capability of the sterilizing and deodorizing device will certainly decrease, such as: after the expiration period, the sterilization function may be decreased, and at this time, the status information may include several status values that can represent "sterilization capability"; after the expiration period, the odour-combating function must decline, at which point the status information may comprise several status values that can characterize the "odour-combating capacity". Therefore, in this step, when it is determined that the capabilities (e.g., sterilization capability, odor removal capability) of the sterilization odor removal apparatus decrease to a certain threshold (i.e., a first predetermined condition is satisfied) based on the status information of the sterilization odor removal apparatus, and/or when it is determined that the capabilities (e.g., sterilization capability, odor removal capability) of the sterilization odor removal apparatus decrease to a certain threshold (i.e., a second predetermined condition is satisfied) based on the status information of the storage compartment, it can be determined that the sterilization odor removal apparatus has passed the expiration date, and the user needs to be reminded to replace the sterilization odor removal apparatus.
Step 103: if so, a prompt for replacing the sterilization and deodorization device is pushed.
Here, in step 102, the judgment condition may be:
(1) the judgment condition is 'judging whether the state information of the sterilization and odor removal device meets a first preset condition', and at the moment, if the state information of the sterilization and odor removal device meets the first preset condition, the judgment result is yes;
(2) the judgment condition is 'judging whether the state information of the storage chamber meets a second preset condition', and at the moment, if the state information of the storage chamber meets the second preset condition, the judgment result is yes;
(3) the judgment condition is 'judging whether the state information of the sterilizing and deodorizing device meets a first preset condition and judging whether the state information of the storage chamber meets a second preset condition', and at the moment, when only the state information of the sterilizing and deodorizing device meets the first preset condition and the state information of the storage chamber meets the second preset condition, the judgment result is yes.
Here, the way of pushing the reminder for replacing the sterilization and deodorization device may be: the display screen displays the prompt, broadcasts the prompt through voice, and sends the prompt to a mobile phone of a user in a short message mode.
In an embodiment of the present invention, the "acquiring status information of the sterilization and odor removal device and/or status information of a storage compartment" specifically includes: acquiring a concentration change value of the odor gas in the storage chamber; wherein, when the concentration change value is a positive number, the concentration of the odorous gas increases; when the concentration change value is negative, the concentration of the odor gas is reduced; here, one function of the sterilizing and deodorizing device is to remove the odor from the air in the storage compartment, and the operation mode can be determined according to actual situations, such as: (1) in the air-cooled refrigerator, the sterilization and odor removal device can be arranged at an air inlet or an air return port, air can flow through the sterilization and odor removal device during refrigeration, the sterilization and odor removal device can remove odor in the air, and when a refrigeration system works, the sterilization and odor removal device also works; (2) can be provided with this odour removal device that disinfects in the storage compartment, can be provided with a fan in this odour removal device that disinfects, when this odour removal device that disinfects during operation, this fan can rotate to the air in the storage compartment will flow through this odour removal device that disinfects, and then the odour removal device that disinfects will filter the peculiar smell gas in the air.
Here, during the operation of the sterilizing and deodorizing device, the concentration value of the odor gas (which may be the concentration value of any odor gas or the sum of the concentration values of all odor gases) may be detected at intervals, so that the concentration variation value of the odor gas can be obtained.
Here, odor sensors may be provided in the storage compartment, and the odor sensors may measure a change value of the concentration of the odor, which may be classified into: (1) a stacked semiconductor type, which is manufactured by using a principle that some metal oxide semiconductor materials have conductivity varying with the change of the components of the ambient gas at a certain temperature, and which can be effectively used for the measurement of the concentration of gases such as methane, ethane, propane, butane, alcohol, formaldehyde, carbon monoxide, carbon dioxide, ethylene, acetylene, vinyl chloride, styrene, acrylic acid, etc.; (2) in the combustion mode, a high-temperature-resistant catalyst layer is prepared on the surface of the platinum resistor, and at a certain temperature, combustible gas is catalytically combusted on the surface of the platinum resistor, so that the platinum resistor is heated by combustion, the resistance is changed, and the change value is a function of the concentration of the combustible gas; (3) each gas has specific thermal conductivity, when the difference between the thermal conductivities of two or more gases is large, the content of one component can be distinguished by using a thermal conductivity element, and the thermal conductivity element can be used for detecting the concentrations of hydrogen, carbon dioxide and high-concentration methane; (3) electrochemically, a substantial portion of flammable, toxic, and harmful gases are electrochemically active, can be electrochemically oxidized or reduced, and so on.
The step of judging whether the state information of the storage compartments meets a second preset condition specifically comprises the following steps: judging whether the concentration change value is larger than a first threshold value or not; the first threshold is less than zero. It will be understood that if the germicidal odor removal apparatus is active, the concentration of odorous gases should decrease relatively quickly (i.e., need to be less than or equal to a first threshold value), and if the concentration change is greater than the first threshold value (especially if the concentration change is greater than zero), this indicates that the germicidal odor removal apparatus is malfunctioning, at which point the user is notified that the germicidal odor removal apparatus has been replaced.
In an embodiment of the present invention, the "acquiring status information of the sterilization and odor removal device or status information of the storage compartment" specifically includes: acquiring the concentration change value of the effective component in the storage chamber; wherein, when the concentration variation value is a positive number, the concentration of the effective component increases; when the concentration change value is negative, the concentration of the effective component is reduced; the effective component is a bactericidal factor or an odor removal factor; here, the sterilizing and deodorizing device may be adapted to sterilize or deodorize the odor by releasing into the storage compartment some effective ingredients that may be used to sterilize or deodorize the odor, such as: releasing ozone, which can be used to kill bacteria; CLO2 is released and CLO2 can be used for removing odor gas and the like.
During the operation of the sterilization and odor removal device, the concentration value of the effective component (which may be the concentration value of any effective component or the sum of the concentration values of all effective components) can be detected at regular intervals, so that the concentration variation value of the effective component can be obtained.
The step of judging whether the state information of the storage compartments meets a second preset condition specifically comprises the following steps: judging whether the concentration change value is smaller than a second threshold value; the second threshold value is less than or equal to zero. Here, it can be understood that the sterilizing and deodorizing device continuously releases the effective components into the storage compartment during the treatment process, and the effective components are continuously consumed, but the concentration of the effective components should not decrease so quickly (i.e. it is required to be greater than or equal to the second threshold value), so that when the concentration of the effective components changes to a value less than the second threshold value, the sterilizing and deodorizing device is confirmed to have passed the effective period.
In the embodiment of the invention, the step of processing the storage compartment by the sterilization and odor removal control device specifically comprises the following steps: controlling the sterilization and deodorization device to emit ultraviolet rays into the storage chamber; here, the ultraviolet ray having a wavelength in the range of 240nm to 280nm has an optimal sterilization effect, and is capable of destroying the molecular structure of DNA (deoxyribonic Acid) or RNA (Ribonucleic Acid) in the bacterial virus, causing death of growing cells and/or regenerative cells, and achieving the sterilization and disinfection effect, and the ultraviolet ray has the strongest sterilization effect particularly at the wavelength of 253.7 nm.
In addition, if a photocatalyst (a general name of a photo-semiconductor material having a photocatalytic function represented by nano-scale titanium dioxide) is coated on the surface of a substrate, a strong catalytic degradation function is generated under the action of ultraviolet light and visible light, toxic and harmful gases in the air can be effectively degraded, various bacteria can be effectively killed, toxins released by bacteria or fungi can be decomposed and harmlessly treated, and the functions of removing formaldehyde, deodorizing, resisting pollution, purifying the air and the like are also provided.
The step of acquiring the state information of the sterilizing and deodorizing device and/or the state information of the storage chamber specifically comprises the following steps: acquiring the intensity value of ultraviolet rays in the storage chamber; the step of judging whether the state information of the storage compartments meets a second preset condition specifically comprises the following steps: and judging whether the intensity value of the ultraviolet rays is smaller than a third threshold value. In practice, to increase the UV-lightThe intensity of the ultraviolet ray is required to be more than a certain value, for example, more than 70 μ W/cm2. Here, the principle of measuring the intensity value of the ultraviolet rays may be: the ordinary silicon photocell does not respond to ultraviolet light, the fluorescent ultraviolet type silicon photocell can respond well to the ultraviolet light part, the two photocells collect light simultaneously, and the ultraviolet light signal in the measured light can be obtained by subtracting the two signals.
In the embodiment of the invention, the bactericidal factor is negative ions. Here, the negative ions can destroy the molecular protein structure of microorganisms such as bacteria and viruses, cause structural changes or energy transfer, and cause the microorganisms such as bacteria and viruses to die, thereby enabling sterilization treatment of the storage compartment.
Here, the concentration value of the negative ions can be measured by the following method: light scattering, membrane weighing, vibration balance measurements and beta-ray measurements. During the operation of the sterilizing and deodorizing device, the concentration value of the negative ions can be detected at intervals, so that the concentration change value of the negative ions can be obtained.
Here, it can be understood that during the treatment process of the sterilizing and deodorizing device, the sterilizing and deodorizing device will continuously release negative ions into the storage compartment, and the negative ions will be continuously consumed, but the concentration of the negative ions should not decrease very quickly (i.e. it needs to be greater than or equal to the fourth threshold), so that when the concentration of the negative ions changes to a value less than the fourth threshold, it can be confirmed that the sterilizing and deodorizing device has passed the effective period.
Optionally, the "acquiring the status information of the sterilization and odor removal device" specifically includes: obtaining the weight or content of a certain ingredient in the sterilization and odor removal module, and the like, such as: the sterilization and odor removal device is provided with an essential oil slow-release diffusion module, a weight sensor is arranged below the essential oil slow-release diffusion module, when the essential oil is slowly released, the weight of the essential oil becomes zero, and therefore the state information of the sterilization and odor removal device can comprise: the weight of the essential oil sustained-release diffusion module; the step of judging whether the state information of the sterilizing and deodorizing device meets a first preset condition specifically comprises the following steps: when the weight of a certain component is less than a first threshold or the content of the certain component is less than a second threshold, a first preset condition is met, such as: if the weight of the essential oil sustained-release diffusion module is zero, the first preset condition is met.
The second embodiment of the invention provides a replacement control device for a sterilization and deodorization device of a refrigerator, which comprises:

Therefore, in the module, when the capabilities (e.g., sterilization capability, odor removal capability) of the sterilization and odor removal device are determined to fall to a certain threshold (i.e., a first preset condition is met) based on the status information of the sterilization and odor removal device, and/or when the capabilities (e.g., sterilization capability, odor removal capability) of the sterilization and odor removal device are determined to fall to a certain threshold (i.e., a second preset condition is met) based on the status information of the storage compartment, it can be determined that the sterilization and odor removal device has passed the validity period, and a user needs to be reminded to replace the sterilization and odor removal device.

In addition, if a photocatalyst (a general name of a photo-semiconductor material having a photocatalytic function represented by nano-scale titanium dioxide) is coated on the surface of a substrate, a strong catalytic degradation function is generated under the action of ultraviolet light and visible light, toxic and harmful gases in the air can be effectively degraded, various bacteria can be effectively killed, toxins released by bacteria or fungi can be decomposed and harmlessly treated, and the functions of removing formaldehyde, deodorizing, resisting pollution, purifying the air and the like are also provided.
The acquisition module is further configured to: acquiring the intensity value of ultraviolet rays in the storage chamber; the judging module is further configured to: and judging whether the intensity value of the ultraviolet rays is smaller than a third threshold value.
In practice, in order to improve the ultraviolet sterilizing effect, the intensity of the ultraviolet light needs to be higher than a certain value, for example, 70 μ W/cm2. Here, the principle of measuring the intensity value of the ultraviolet rays may be: the ordinary silicon photocell does not respond to ultraviolet light, the fluorescent ultraviolet type silicon photocell can respond well to the ultraviolet light part, the two photocells collect light simultaneously, and the ultraviolet light signal in the measured light can be obtained by subtracting the two signals.
In the embodiment of the invention, the bactericidal factor is negative ions. Here, the negative ions can destroy the molecular protein structure of microorganisms such as bacteria and viruses, cause structural changes or energy transfer, and cause the microorganisms such as bacteria and viruses to die, thereby enabling sterilization treatment of the storage compartment.
Here, the concentration value of the negative ions can be measured by the following method: light scattering, membrane weighing, vibration balance measurements and beta-ray measurements. During the operation of the sterilizing and deodorizing device, the concentration value of the negative ions can be detected at intervals, so that the concentration change value of the negative ions can be obtained.
Here, it can be understood that during the treatment process of the sterilizing and deodorizing device, the sterilizing and deodorizing device will continuously release negative ions into the storage compartment, and the negative ions will be continuously consumed, but the concentration of the negative ions should not decrease very quickly (i.e. it needs to be greater than or equal to the fourth threshold), so that when the concentration of the negative ions changes to a value less than the fourth threshold, it can be confirmed that the sterilizing and deodorizing device has passed the effective period.
