[0036] It should be understood that the specific embodiments described herein are intended to explain the present application and are not intended to limit the present application.

[0037] Referring to Figure 1 , Figure 1 is a structural schematic view of a refrigerator related to a hardware running environment of an embodiment of the present application.

[0038] As Figure 1As shown in the refrigerator, the refrigerator can include: a processor 1001, for example, a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, a memory 1005. Among them, the communication bus 1002 is used to realize the connection communication between these components. The user interface 1003 can include a display screen (Display), an input unit such as a keyboard (Keyboard), and the optional user interface 1003 can also include a standard wired interface, a wireless interface. The network interface 1004 can optionally include a standard wired interface, a wireless interface (such as a wireless fidelity (Wireless-Fidelity, Wi-Fi) interface). The memory 1005 can be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 1005 can also be an independent storage device from the aforementioned processor 1001.

[0039] Those skilled in the art can understand that Figure 1 The structure shown in the figure does not constitute a limitation on the refrigerator, and can include more or fewer components than the figure, or combine certain components, or different component arrangements.

[0040] As Figure 1 As shown, the memory 1005 as a storage medium can include an operating system, a network communication module, a user interface module, and a sensor life extension program.

[0041] In Figure 1 In the refrigerator shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the refrigerator of the present application can be arranged in the refrigerator, and the refrigerator calls the sensor life extension program stored in the memory 1005 through the processor 1001, and executes the method for extending the life of the sensor provided by the embodiment of the present application.

[0042] The embodiment of the present application provides a method for extending the life of the sensor, referring to Figure 2 , Figure 2 The flowchart of the first embodiment of the method for extending the life of the sensor of the present application.

[0043] In this embodiment, the method for extending the life of the sensor includes the following steps:

[0044] Step S10: Start the deodorizing device in the household appliance to remove odor.

[0045] In the embodiment, the execution subject of the embodiment can be a sensor life extension device, which can be an electronic device such as a personal computer or a server, or a controller in a food storage device such as a refrigerator. The embodiment is not limited in this regard, and the method for extending the life of a sensor is described below with reference to a sensor life extension device.

[0046] It should be noted that the household appliance in the embodiment includes but is not limited to a food storage device such as a refrigerator. The plastic liner in the food storage device such as a refrigerator can volatilize odor gas, and the food residue existing inside the food storage device such as a refrigerator can also volatilize odor gas. Therefore, when the food storage device such as a refrigerator is powered on for the first time or after a long period of non-use, a high-concentration odor environment is formed inside the food storage device such as a refrigerator.

[0047] The food storage device such as a refrigerator is provided with an odor removal device and an odor detection sensor. The odor removal device is used to purify the air inside the food storage device such as a refrigerator to remove the odor inside the food storage device such as a refrigerator, thereby achieving the purpose of reducing the concentration of odor gas. The odor detection sensor is a gas sensor used to detect the concentration of odor gas in the food storage device such as a refrigerator.

[0048] In view of the high-concentration odor environment formed inside the food storage device such as a refrigerator, the usual way is to start the odor detection sensor when the food storage device such as a refrigerator is powered on for the first time or after a long period of non-use. The odor detection sensor detects the odor concentration inside the food storage device such as a refrigerator to obtain a specific concentration value, which is then compared with a pre-set concentration value. If the detected concentration value is less than the pre-set concentration value, it means that the concentration of odor gas inside the food storage device such as a refrigerator is low, and in this case, the odor removal device is not started for purification. If the detected concentration is greater than or equal to the pre-set concentration value, it means that the concentration of odor gas inside the food storage device such as a refrigerator is low, and in this case, the odor removal device is started for purification to reduce the concentration of odor gas.

[0049] However, this approach has a problem that the current approach causes the odor sensor to detect the gas concentration in a high-odor gas concentration environment, which accelerates the aging of the odor sensor and further causes the performance of the odor sensor to degrade, thereby reducing the service life of the odor sensor.

[0050] In the embodiment, to solve the above problem, the odor sensor is started after the odor gas concentration in the high-odor gas concentration environment is relatively reduced. The specific process can be implemented in the following manner.

[0051] In a specific implementation, in order to reduce the concentration of odor gas, in the embodiment, after detecting that the household appliance is powered on, the odor removal device is first turned on to perform odor removal operation, and the concentration of odor gas in the household appliance can be reduced before the odor sensor is started through the odor removal operation of the odor removal device. It should be emphasized that the odor sensor is always in a state of stopping working when the odor removal device starts to remove odor.

[0052] It is easy to understand that the food storage device such as a refrigerator will also perform real-time odor removal operation in the process of being used by the user, and therefore the household appliance used by the user in daily life, i.e., the household appliance frequently used, will not usually form an environment with high-concentration odor gas. The embodiment is directed to the household appliance started for the first time and the household appliance that has been idle for a long time after being used, i.e., the household appliance that has not been used for a long time. Specifically, after the household appliance is powered on, the embodiment detects whether the household appliance is the household appliance started for the first time or the household appliance started for the first time after being idle for a long time. The specific detection process can be implemented in the following manner.

[0053] In a specific implementation, the embodiment first determines the usage state of the household appliance, which includes the first-time usage state, the long-time non-usage state, and the frequent usage state. The first-time usage state indicates that the user uses the household appliance for the first time, which usually means that the user newly purchases the household appliance. The long-time non-usage state indicates that the user has used the household appliance before, but has been idle for a long time before being used again. The frequent usage state indicates that the user uses the household appliance to store food materials every day.

[0054] In the embodiment, the usage state of the household appliance can be determined in the following manner.

[0055] In a specific implementation, for the household appliance frequently used by the user, such as a refrigerator, in order to ensure the freshness of food materials, the household appliance will be powered on again in a short time after an unexpected power failure, for example, the power failure occurs at 4 a.m., but the power supply is restored at 6 a.m., and the household appliance is powered on again at 6 a.m.

[0056] However, for the household appliance that has not been used for a long time or has been used for the first time, the household appliance will be powered on again after a long interval after the last power failure, for example, the last power failure of the household appliance occurs on January 1, and the household appliance is powered on again on July 1, and the interval between the power failure and the powering on again is 6 months.

[0057] In a specific implementation, the current time when the household appliance is powered on is obtained, and the time when the last power-off occurs, i.e., the historical time. In the above example, 4 a.m. and January 1 are the historical time of the last power-off, and 6 a.m. and July 1 are the current time of power-on. Based on the obtained current time and historical time, the time difference can be calculated to determine the usage state of the household appliance.

[0058] Specifically, the calculated time difference can be compared with a preset time difference in the embodiment. If the time difference is less than the preset time difference, it can be determined that the household appliance is in a frequently used state. If the time difference is greater than or equal to the preset time difference, it can be determined that the household appliance is in a first use state or a long-term non-use state. The preset time difference can be set according to actual needs, and the embodiment is not limited in this regard.

[0059] Further, through the determination of the usage state, it can be determined whether the household appliance is in a first power-on or long-term non-use and re-power-on state. If the household appliance meets a preset condition, it can be determined that the corresponding household appliance is in a first power-on or long-term non-use and re-power-on state. Otherwise, if the household appliance does not meet the preset condition, it can be determined that the corresponding household appliance does not belong to the first power-on or long-term non-use and re-power-on state. The usage state corresponding to the preset condition is a first use state or a long-term non-use state.

[0060] Step S20: Start the odor detection sensor in the household appliance.

[0061] In a specific implementation, after the odor removal device is turned on, the odor removal operation performed by the odor removal device can effectively purify the odor gas in the household appliance, thereby reducing the concentration of the odor gas and making the concentration of the odor gas reach a relatively low concentration level.

[0062] After the concentration of the odor gas is relatively reduced, the odor detection sensor is turned on again in the embodiment. At this time, the odor detection sensor changes from detecting the gas concentration in a high odor gas concentration environment to detecting the gas concentration in a relatively low odor gas concentration environment. This mode in the embodiment can effectively avoid the influence of high concentration odor on the sensor, reduce the aging speed of the odor sensor and the performance degradation of the odor sensor, and prolong the service life of the odor sensor.

[0063] The embodiment prolongs the service life of the sensor by starting the odor removal device in the household appliance when the household appliance is powered on, and starting the odor detection sensor in the household appliance after the odor removal device starts to remove odor.

[0064] Reference Figure 3 , Figure 3 The flowchart of the second embodiment of the method for prolonging the service life of the sensor.

[0065] Based on the first embodiment, the method for prolonging the service life of the sensor further comprises the following steps before step S20:

[0066] Step S020: Record the odor removal working time of the odor removal device.

[0067] It should be noted that the odor removal device needs to spend a certain time to remove odor, and it is easy to understand that the longer the time spent, the better the odor removal effect, and the lower the concentration of odor gas in the household appliance. Therefore, in the embodiment, the odor removal working time of the odor removal device is recorded after the odor removal device is started.

[0068] Further, in order to ensure that the concentration of odor gas can be effectively reduced, the recorded odor removal working time is compared with a preset time in the embodiment. If the odor removal working time does not reach the preset time, it means that the household appliance is still in an environment with high concentration of odor gas. On the contrary, if the odor removal working time reaches the preset time, it means that the concentration of odor gas in the household appliance has been reduced to a relatively low level. In this case, the odor sensor is started in the embodiment to effectively avoid the odor sensor in a high concentration environment. The preset time can be set according to the actual odor removal requirement, which is not limited in the embodiment.

[0069] The embodiment can effectively ensure that the concentration of odor gas in the household appliance is reduced to a low concentration by recording the odor removal working time of the odor removal device and then starting the odor sensor after the odor removal working time of the odor removal device meets the preset time. Further, the influence of high concentration odor on the sensor is effectively avoided, the aging speed of the odor sensor and the performance degradation of the odor sensor are reduced, and the service life of the odor sensor is prolonged.

[0070] Reference Figure 4 , Figure 4 The flowchart of the third embodiment of the method for prolonging the service life of the sensor.

[0071] Based on the first embodiment, a third embodiment of the method for prolonging the service life of the sensor is provided.

[0072] In this embodiment, after the step S20, the method further comprises:

[0073] Step S30: obtaining the current gas concentration in the home appliance.

[0074] In a specific implementation, after the odor sensor is turned on, the gas concentration in the home appliance can be detected by the odor sensor, and the current gas concentration obtained in this embodiment is collected by the odor sensor.

[0075] Step S40: controlling the working state of the odor removal device according to the current gas concentration.

[0076] It should be noted that the odor removal device acts to reduce the odor gas concentration in the home appliance, and the working state of the odor removal device can be controlled based on the current gas concentration collected by the odor sensor in this embodiment.

[0077] Further, in this embodiment, the current gas concentration is compared with the preset concentration threshold value, if the current gas concentration is less than the preset concentration threshold value, it indicates that the odor gas concentration of the home appliance is low at this time, otherwise, if the current gas concentration is greater than or equal to the preset concentration threshold value, it indicates that the odor gas concentration of the home appliance is high at this time. When the odor gas concentration of the home appliance is low, the home appliance does not need to be purified, in this case, the odor removal operation of the odor removal device is terminated, and the odor removal device is controlled to stop working. When the odor gas concentration of the home appliance is high, the home appliance needs to continue to be purified, in this case, the odor removal device continues to be in an open state until the current gas concentration is reduced to below the preset concentration threshold value. The preset concentration threshold value can be set according to actual purification requirements, which is not limited in this embodiment.

[0078] In this embodiment, the current gas concentration in the home appliance is obtained, and the working state of the odor removal device is controlled according to the current gas concentration. After the odor sensor is turned on, the working state of the odor removal device is adjusted according to the gas concentration detected by the odor sensor, so that the intelligent adjustment of the odor removal device in the home appliance is ensured.

[0079] In addition, an embodiment of the present application further provides a storage medium, and the storage medium stores a program for prolonging the service life of the sensor. When the program for prolonging the service life of the sensor is executed by a processor, the steps of the method for prolonging the service life of the sensor are implemented.

[0080] Since the storage medium adopts all the technical solutions of the above embodiments, it has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0081] With reference to Figure 5 , Figure 5 The structure block diagram of the first embodiment of the device for prolonging the service life of a sensor.

[0082] As Figure 5 shown, the device for prolonging the service life of a sensor includes:

[0083] The detection module 10 is configured to start the odor removal device in the household appliance to remove odor when it is detected that the household appliance is powered on.

[0084] In the embodiment, the execution subject of the embodiment can be a device for prolonging the service life of a sensor, which can be an electronic device such as a personal computer or a server, or a controller in a food storage device such as a refrigerator. The embodiment is not limited in this regard, and the method for prolonging the service life of a sensor will be described in the embodiment and the following embodiments with the device for prolonging the service life of a sensor as an example.

[0085] It should be noted that the household appliance in the embodiment includes but is not limited to a food storage device such as a refrigerator. The plastic liner in the food storage device such as a refrigerator can volatilize odor gas, and the food residue existing in the food storage device such as a refrigerator can also volatilize odor gas. Therefore, when the food storage device such as a refrigerator is powered on for the first time or after a long period of non-use, a high-concentration odor environment will be formed inside the food storage device such as a refrigerator.

[0086] The food storage device such as a refrigerator is provided with an odor removal device and an odor detection sensor. The odor removal device is used to purify the air in the food storage device such as a refrigerator to remove the odor in the food storage device such as a refrigerator, so as to reduce the concentration of odor gas. The odor detection sensor is a gas sensor used to detect the concentration of odor gas in the food storage device such as a refrigerator.

[0087] For the high concentration odor environment formed in the interior of the food storage equipment such as refrigerator, the common method is to start the odor detection sensor when the food storage equipment such as refrigerator is powered on for the first time or powered on after long-term non-use, detect the odor concentration in the food storage equipment such as refrigerator through the odor detection sensor, and obtain the specific concentration value, and then compare the concentration with the pre-set concentration value. If the detected concentration value is less than the pre-set concentration value, it means that the concentration of odor gas in the food storage equipment such as refrigerator is low, and in this case, the odor removal device is not started for purification. If the detected concentration is greater than or equal to the pre-set concentration value, it means that the concentration of odor gas in the food storage equipment such as refrigerator is low, and in this case, the odor removal device is started for purification to reduce the concentration of odor gas.

[0088] However, the problem of this method is that the current method will make the odor sensor detect the gas concentration in a high odor gas concentration environment, which will accelerate the aging of the odor sensor, and further cause the performance degradation of the odor sensor, reducing the service life of the odor sensor.

[0089] In order to solve the above problems in the embodiment, the odor sensor is started after the odor gas concentration in the high odor gas concentration environment is relatively reduced, and the specific process can be realized in the following manner.

[0090] In the specific implementation, in order to reduce the concentration of odor gas, the odor removal device is turned on after the detection of the power-on of the household appliance in the embodiment, and the odor removal device is controlled to perform odor removal operation first. The odor removal operation of the odor removal device can reduce the odor gas concentration in the household appliance before the odor sensor is started. It should be emphasized that the odor sensor is always in a stopped state when the odor removal device starts to remove odor.

[0091] It is easy to understand that the odor removal device will also perform odor removal operation in real time during the user's normal use of the refrigerator and other food storage equipment, so the household appliance used by the user in normal use, i.e. the household appliance frequently used, will not form a high-concentration odor gas environment. The embodiment is aimed at the household appliance started for the first time and the household appliance which has been idle for a long time after use, i.e. the long-term non-use household appliance. Specifically, after the household appliance is powered on, the embodiment will detect whether the household appliance is the household appliance powered on for the first time or the household appliance powered on after long-term non-use, and the specific detection process can be realized in the following manner.

[0092] In a specific implementation, the use state of the home appliance is determined in the embodiment, the use state includes a first use state, a long-term non-use state and a frequent use state, the first use state indicates that the user uses the home appliance for the first time, which is usually that the user newly purchases the home appliance, the long-term non-use state indicates that the user has used the home appliance before, but has not used it for a long time, and the frequent use state indicates that the user uses the home appliance to store food materials every day.

[0093] In the embodiment, the use state corresponding to the home appliance can be determined in the following manner.

[0094] In a specific implementation, for the home appliance frequently used by the user, such as a refrigerator, in order to ensure the freshness of food materials, the home appliance is powered on again in a short time when a power failure occurs unexpectedly, for example, the power failure occurs at 4 a.m., but the power supply is restored at 6 a.m., and the home appliance is powered on again at 6 a.m.

[0095] However, for the home appliance that is used for the first time or has not been used for a long time, the home appliance is powered on again after a long time interval after the last power failure, for example, the last power failure of the home appliance is on January 1, and the home appliance is powered on again on July 1, and the interval between the power failure and the power-on again is 6 months.

[0096] In a specific implementation, the current time when the home appliance is powered on and the time when the last power failure occurs, that is, the historical time, are obtained in the embodiment, for example, 4 a.m. and January 1 are the historical time of the last power failure, and 6 a.m. and July 1 are the current time of the power-on, based on the obtained current time and historical time, the time difference can be calculated to determine the use state of the home appliance.

[0097] Specifically, the calculated time difference can be compared with a preset time difference in the embodiment, if the time difference is less than the preset time difference, it can be determined that the home appliance is in a frequent use state, if the time difference is greater than or equal to the preset time difference, it can be determined that the home appliance is in a first use state or a long-term non-use state, wherein the preset time difference can be set according to actual needs, and the embodiment does not limit this.

[0098] Further, by using the state judgment, it can be determined whether the household appliance is powered on for the first time or powered on again after a long period of non-use. If the household appliance meets the preset condition, it can be determined that the corresponding household appliance is powered on for the first time or powered on again after a long period of non-use. Otherwise, if the household appliance does not meet the preset condition, it can be determined that the corresponding household appliance does not belong to the case of being powered on for the first time or powered on again after a long period of non-use, wherein the preset condition corresponds to the first use state or the long period of non-use state.

[0099] The control module 20 is configured to start the odor detection sensor in the household appliance after the odor removal of the odor removal device.

[0100] In a specific implementation, after the odor removal device is started, the odor removal operation of the odor removal device can effectively purify the odor gas in the household appliance, so as to reduce the concentration of the odor gas and make the concentration of the odor gas reach a relatively low concentration level.

[0101] After the concentration of the odor gas is relatively reduced, the odor detection sensor in the embodiment is started again. At this time, the odor detection sensor is switched from detecting the gas concentration in a high odor gas concentration environment to detecting the gas concentration in a relatively low odor gas concentration environment. This mode in the embodiment can effectively avoid the influence of high concentration odor on the sensor, reduce the aging speed of the odor sensor and the performance attenuation of the odor sensor, and prolong the service life of the odor sensor.

[0102] The embodiment starts the odor removal device in the household appliance to remove odor when detecting that the household appliance is powered on, and starts the odor detection sensor in the household appliance after the odor removal of the odor removal device. By starting the odor removal device to purify the odor in the household appliance when the household appliance is powered on, and starting the odor detection sensor in the household appliance after the concentration of the odor is relatively reduced, the influence of high concentration odor on the sensor can be effectively avoided, and the service life of the odor sensor is prolonged.
