The specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.

Referring to fig. 1, fig. 1 is a schematic view of an external structure of a refrigerator 100 according to an embodiment of the present invention, where the refrigerator 100 has an approximately rectangular parallelepiped shape, and includes a case defining a storage space and a plurality of door bodies provided at an opening of the case, and the door bodies include a door body housing located outside the case, a door body liner located inside the case, an upper end cover, a lower end cover, and a heat insulating layer located between the door body housing, the door body liner, the upper end cover, and the lower end cover; typically, the insulating layer is filled with a foaming material. The cabinet is provided with a chamber including a component storage chamber for storing components in the refrigerator, such as a compressor, and a storage space for storing food and the like.

Referring to fig. 2, fig. 2 is a schematic view illustrating an internal structure of a refrigerator 100 according to an embodiment of the present invention. The storage space may be partitioned into a plurality of storage compartments, which may be configured as the refrigerating compartment 10, the freezing compartment 20, etc., according to the use. Each storage chamber is provided with one or more doors, for example, the upper storage chamber is provided with a double door. The door body can be pivoted at the opening of the box body and can also be opened in a drawer mode, so that drawer type storage is realized. The odor detection device 11 is arranged in the storage room, and the odor detection device 11 is used for detecting the gas concentration of the storage room; for example, as shown in fig. 2, at least one odor detecting device 11 is installed in the refrigerating chamber 10, in order to avoid deviation of the detected gas concentration caused by only one odor detecting device 11, the odor detecting devices 11 may be arranged according to the arrangement mode of the shelves in the refrigerating chamber 10, for example, one odor detecting device 11 is correspondingly arranged on each shelf, and then when the gas concentration of the refrigerating chamber 10 is calculated, the average value of the detected values of the odor detecting devices 11 in a plurality of refrigerating chambers 10 is taken as the real-time gas concentration value of the current storing chamber. At least a sterilizing and purifying device 12 is installed in the storage room, and the sterilizing and purifying device 12 is used for sterilizing and purifying the storage room.

Referring to fig. 3, fig. 3 is a schematic structural view of a drawer in a refrigerator 100 according to an embodiment of the present invention, when the drawer is disposed in the refrigerator, for example, when the drawer is disposed in a refrigerating chamber 10, at least one odor detecting device 11 and at least one sterilizing and purifying device 12 should be separately disposed in the drawer because the drawer is sealed. For example, as shown in fig. 3, the odor detecting device 11 may be installed in a side wall of the drawer, and the sterilizing and purifying device 12 may be installed at a bottom of the drawer, or may be installed at a side wall, or at a top of the drawer.

Referring to fig. 4, fig. 4 is a schematic view showing a structure of a refrigerating system in a refrigerator 100 according to an embodiment of the present invention, the refrigerating system including a compressor 1, a condenser 2, an anti-condensation pipe 3, a dry filter 4, a capillary 5, an evaporator 6, and a gas-liquid separator 7. The working processes of the refrigeration system comprise a compression process, a condensation process, a throttling process and an evaporation process.

The compression process comprises the following steps: when the power line of the refrigerator is inserted and the contact of the temperature controller is connected, the compressor 1 starts to work, the low-temperature and low-pressure refrigerant is sucked by the compressor 1, compressed into high-temperature and high-pressure overheat gas in the cylinder of the compressor 1 and then discharged to the condenser 2; the condensation process is as follows: the high-temperature and high-pressure refrigerant gas radiates heat through the condenser 2, the temperature is continuously reduced, the refrigerant gas is gradually cooled into normal-temperature and high-pressure saturated steam, the saturated steam is further cooled into saturated liquid, the temperature is not reduced any more, the temperature at the moment is called as condensing temperature, and the pressure of the refrigerant in the whole condensing process is almost unchanged; the throttling process is as follows: the condensed refrigerant saturated liquid is filtered by a dry filter 4 to remove moisture and impurities, and then flows into a capillary tube 5, throttling and depressurization are carried out through the capillary tube, and the refrigerant is changed into normal-temperature and low-pressure wet vapor; the evaporation process is as follows: the wet vapor with normal temperature and low pressure starts to absorb heat in the evaporator 6 for vaporization, so that the temperature of the evaporator and the surrounding temperature are reduced, the refrigerant is changed into low-temperature and low-pressure gas, the refrigerant coming out of the evaporator 6 returns to the compressor 1 again after passing through the gas-liquid separator 7, the process is repeated, and the heat in the refrigerator is transferred into the air outside the refrigerator, so that the purpose of refrigeration is realized.

Specifically, the controller in the refrigerator is used for: acquiring a real-time gas concentration value of a storage room where the odor detection device detects the odor detection device, and acquiring a plurality of pre-stored gas concentration intervals; comparing the real-time gas concentration value with the gas concentration interval to determine a target working mode of the sterilizing and purifying device; and adjusting the working mode of the sterilizing and purifying device to be the target working mode.

Referring to fig. 5, fig. 5 is a first workflow diagram of a controller configured to perform steps S11 to S13 according to an embodiment of the present invention. After the refrigerator is powered on, the refrigerator defaults to start the odor detection device, and a user can also manually select to not start the refrigerator purification function, so that the odor detection device is closed at the moment, and the sterilization purification device is also closed. After the odor detection device is started, acquiring a real-time gas concentration value P of the storage room and a plurality of pre-stored gas concentration intervals. Wherein, each gas concentration interval corresponds to the working mode of the sterilizing and purifying device, such as mode M1, mode M2 and mode M3, and the working strength is M1 < M2 < M3. The gas concentration interval is divided by a plurality of gas concentration thresholds, such as thresholds P1, P2 and P3, wherein the gas concentration thresholds are calculated by overlapping initial concentration values with different fixed values, and the initial concentration values are obtained based on user evaluation parameters when the refrigerator is powered on for the first time. Setting the scent concentration threshold value P1, P2, P3 according to the initial concentration value P0, the P3 > P2 > P1 > P0, in a specific embodiment: p1=p0+5 (fixed value), p2=p0+30 (fixed value), p3=p0+60 (fixed value). The gas concentration interval of the composition includes: [ P1, P2), [ P2, P3), [ P3, + ]. When P is E [ P1, P2), the peculiar smell concentration is lower, strong sterilization effect is not needed, and the working mode of the sterilization and purification device is adjusted to be M1; when P is P2, P3), the peculiar smell concentration is higher, stronger sterilization effect is needed, and the working mode of the sterilization and purification device is adjusted to be M2; when P is P3, + and the odor concentration is high, strong sterilization effect is needed, and the working mode of the sterilization and purification device is adjusted to be M3.

Specifically, an operation period and a circulation number of the current operation mode are preset in the operation mode of the sterilization and purification device, one operation period comprises an operation time length and a shutdown time length, and the operation time length is obtained by converting the residual volume of the current storage chamber; wherein the working time length and the residual volume are in inverse proportion.

For example, the operating rules for the different modes of operation may refer to Table 1. In table 1, s1 represents an adjustment value of the operation time period, for example, in the range of 5 to 10 seconds, which is determined according to the remaining volume of the storage chamber, and when the remaining volume is smaller, it means that the more the storage chamber is stored, the more the odor is generated, and the longer the operation is required. s2 is the adjustment value of the machine halt time length, which can be a fixed value of 5s, or a dynamic value, such as 50-70 s, and is in direct proportion relation with the residual volume. T1-T3 are the number of cycles of the operation period, and the number of cycles is greater as the level of the operation mode increases, such as T1 of 80, T2 of 100, and T3 of 125, corresponding to the operation mode. After the circulation is finished, the real-time gas concentration value is continuously detected, and the steps S11 to S13 are repeated. If the residual volume of the refrigerating chamber is small, s1 is 10s and s2 is 50s correspondingly, and the sterilizing and purifying device is in an M1 mode, and is in a shutdown state for 55s every 12s, and the current mode is ended after 80 times of operation.

Table 1 operation rule settings in operation mode

Mode of operation	Trigger condition	Operation rule	Run cycle
				M1	P1≤p＜P2	Running for s1+2 seconds, stopping for s2+5 seconds,	run T1 cycles
M2	P2≤p＜P3	Operating for s1+5 seconds, stopping for s2+5 seconds,	run T2 cycles
				M3	P＞P3	Running for s1+5 seconds, stopping for s2 seconds,	run T3 cycles

Specifically, after step S13 is performed, the controller in the refrigerator is configured to: acquiring prompt information corresponding to the target working mode; the prompt message is used for informing the user of the current air freshness of the storeroom and reminding the user of whether food material cleaning operation is needed or not; and when the sterilizing and purifying device operates in the target working mode, sending out the prompt information.

Referring to fig. 6, fig. 6 is a second workflow diagram of a controller according to an embodiment of the present invention, and after step S13 is performed, the controller is further configured to perform steps S14 to S15. When the refrigerator runs in the M1 mode, the air in the refrigerator is judged to be good in freshness, but slight peculiar smell is felt, and a user is prompted to check whether food materials with large smell exist in the clinic or not; when the refrigerator runs in the M2 mode, the refrigerator is judged to have common air freshness, obvious peculiar smell is felt, and a user is reminded to check and clean out expired food materials possibly; and when the refrigerator runs in the M3 mode, judging that food materials in the refrigerator are deteriorated and rotten, and reminding a user to immediately clean and clean the refrigerator.

Specifically, the controller in the refrigerator is used for: responding to the first power-on operation of the refrigerator, starting the sterilization and purification device and controlling the sterilization and purification device to work in a preset lowest intensity mode; after the sterilizing and purifying device stops running, acquiring a gas concentration value detected by the odor detection device; when the evaluation parameters input by the user are acquired, calculating the initial concentration value based on the weight value corresponding to the evaluation parameters and the gas concentration value; the evaluation parameters comprise at least two evaluation grades, and each evaluation grade has a corresponding weight value; and when the evaluation parameters input by the user are not acquired, acquiring a default weight value and the gas concentration value to calculate the initial concentration value.

Referring to fig. 7, fig. 7 is a third workflow diagram of a controller configured to perform steps S21 to S27 according to an embodiment of the present invention:

s21, judging whether the refrigerator is electrified for the first time, if so, executing the step S22, and if not, directly ending the flow.

S22, when the refrigerator is powered on for the first time, starting the sterilizing and purifying device, enabling the controller to work in a preset minimum intensity mode M0, and then entering step S23.

For example, M0 is less than M1, because the refrigerator is powered on for the first time, the storage room does not store or store less articles, and weak sterilization operation is started at this time, so that the operation rule of the refrigerator can be set by a user for purifying the peculiar smell of the refrigerator which exists due to long-term unopened refrigerator.

S23, judging whether the sterilizing and purifying device stops running, if so, entering a step S24, and if not, continuing to execute the step S23.

S24, after the sterilizing and purifying device is operated, acquiring a gas concentration value detected by the odor detection device, and then entering step S25.

S25, judging whether the user evaluation parameters are acquired, if so, proceeding to step S26, otherwise, proceeding to step S27.

For example, there are two ways to obtain the user evaluation parameters, one is obtained through a display screen of the refrigerator, and the other is obtained through a mobile terminal connected in advance to the refrigerator. If the user is prompted to evaluate the refrigerator odor at this time, and no reply is received for a long time, the initial concentration value needs to be calculated by adopting a default mode.

S26, after the user evaluation parameters are acquired, calculating the initial concentration value based on the weight value corresponding to the evaluation parameters and the gas concentration value.

For example, detecting the gas concentration value p0 in the air in the refrigerator, acquiring the evaluation of the freshness of the air in the refrigerator by a user, determining an evaluation coefficient K according to the evaluation result, and calculating the initial concentration PO of the smell in the air in the refrigerator. The evaluation parameters are classified into three grades of excellent, good and general, the corresponding evaluation weight values are respectively 0.5K, K and 1.5K, so that the initial odor concentrations corresponding to the high (H), medium (M) and low (L) odor sensitivities are respectively POH=0.5 KpO, POM=KpO and POL=1.5 KpO.

And S27, when the evaluation parameters input by the user are not acquired, acquiring a default weight value and the gas concentration value, and calculating the initial concentration value.

For example, if the refrigerator is powered on for the first time and fails to obtain the evaluation result of the user, the default weight value is K, and at this time, the initial concentration value is pom= KpO.

Specifically, the controller in the refrigerator is used for: displaying an operation window in a display screen in the refrigerator, and acquiring user input operation to obtain evaluation parameters input by a user; wherein, a plurality of evaluation grades are displayed on the operation window.

Referring to fig. 8, fig. 8 is a fourth operation flowchart of the controller according to the embodiment of the present invention, and the step S25 specifically includes steps S251 to S252.

Specifically, the controller in the refrigerator is used for: sending a prompt operation to a mobile terminal which is connected with the refrigerator in advance so as to prompt a user to feed back the evaluation parameters according to the prompt operation; wherein, the prompt operation is provided with a plurality of evaluation grades.

Referring to fig. 9, fig. 9 is a schematic information interaction diagram of a refrigerator 100 and a client 200 according to an embodiment of the present invention, where the refrigerator 100 establishes a data connection with the client 200 through a router 300 or a cloud server 400. When the refrigerator 100 and the client 200 communicate through the router 300, the refrigerator 100 and the client 200 are closely spaced, and a user can view the operation condition of the refrigerator or the storage condition of food materials placed in a kitchen in a living room or a room. When the refrigerator 100 and the client 200 communicate through the cloud server 400, the refrigerator 100 and the client 200 are far apart, and a user can perform data interaction with the refrigerator 100 through an APP installed in the client 200, and meanwhile, remote control of the refrigerator 100 can be realized.

Referring to fig. 10, fig. 10 is a fifth workflow diagram of the controller according to the embodiment of the present invention, and the step S25 specifically includes steps S253 to S254.

Referring to fig. 11, fig. 11 is a schematic diagram of a display interface for prompting operation in a mobile terminal according to an embodiment of the present invention, where options and explanations corresponding to different odor sensitivities are provided on the display interface, so that a user can conveniently select the options. Options of the display interface include: (1) high: the method is suitable for people particularly sensitive to peculiar smell, and the food materials can be identified, reminded and started for sterilization and purification after being slightly rotted to emit peculiar smell Ai-Nose, but false alarm can also exist. (2) In (a): the method is suitable for people with moderate odor sensitivity, and is also a recommended grade verified according to a large amount of experimental data. (3) Low: the odor detection kit is suitable for people insensitive to odor, and Ai-Nose has low odor detection sensitivity in the refrigerator, so that reminding caused by odor detection is reduced.

Compared with the prior art, the refrigerator disclosed by the invention has the advantages that the sensitivity degree of a user to the initial smell of the refrigerator is recorded when the refrigerator is powered on for the first time, and then different concentration judgment thresholds are set based on the sensitivity degree, so that the subsequent refrigerator concentration judgment is more in line with the actual experience of the user, the personalized requirements of different people are met, and the user experience is good; the refrigerator is provided with the sterilizing and purifying device, the working strength is dynamically adjusted according to the concentration value of the peculiar smell, and the intelligent degree and the purifying effect can be effectively improved.

Referring to fig. 12, fig. 12 is a flowchart of a method for purifying a refrigerator odor according to an embodiment of the present invention. An odor detection device for detecting the gas concentration in the storage chamber and a sterilization and purification device for sterilizing and purifying the storage chamber are arranged in the storage chamber of the refrigerator. The refrigerator peculiar smell purifying method comprises the following steps:

s1, acquiring a real-time gas concentration value of a storage room where the odor detection device detects the odor detection device, and acquiring a plurality of pre-stored gas concentration intervals;

s2, comparing the real-time gas concentration value with the gas concentration interval to determine a target working mode of the sterilizing and purifying device;

s3, adjusting the working mode of the sterilizing and purifying device to be the target working mode.

For example, after the refrigerator is powered on, the refrigerator defaults to start the odor detection device, and the user can also manually select to not start the refrigerator purification function, so that the odor detection device is turned off and the sterilization purification device is also turned off at the moment. After the odor detection device is started, acquiring a real-time gas concentration value P of the storage room and a plurality of pre-stored gas concentration intervals. Wherein, each gas concentration interval corresponds to the working mode of the sterilizing and purifying device, such as mode M1, mode M2 and mode M3, and the working strength is M1 < M2 < M3. The gas concentration interval is divided by a plurality of gas concentration thresholds, such as thresholds P1, P2 and P3, wherein the gas concentration thresholds are calculated by overlapping initial concentration values with different fixed values, and the initial concentration values are obtained based on user evaluation parameters when the refrigerator is powered on for the first time. Setting the scent concentration threshold value P1, P2, P3 according to the initial concentration value P0, the P3 > P2 > P1 > P0, in a specific embodiment: p1=p0+5 (fixed value), p2=p0+30 (fixed value), p3=p0+60 (fixed value). The gas concentration interval of the composition includes: [ P1, P2), [ P2, P3), [ P3, + ]. When P is E [ P1, P2), the peculiar smell concentration is lower, strong sterilization effect is not needed, and the working mode of the sterilization and purification device is adjusted to be M1; when P is P2, P3), the peculiar smell concentration is higher, stronger sterilization effect is needed, and the working mode of the sterilization and purification device is adjusted to be M2; when P is P3, + and the odor concentration is high, strong sterilization effect is needed, and the working mode of the sterilization and purification device is adjusted to be M3.

Specifically, the method further comprises: acquiring prompt information corresponding to the target working mode; the prompt message is used for informing the user of the current air freshness of the storeroom and reminding the user of whether food material cleaning operation is needed or not; and when the sterilizing and purifying device operates in the target working mode, sending out the prompt information.

For example, when the refrigerator runs in the M1 mode, the air in the refrigerator is judged to be good in freshness, but slight peculiar smell is felt, and at the moment, a user is prompted to check whether the food materials with a period and a large smell are available or not; when the refrigerator runs in the M2 mode, the refrigerator is judged to have common air freshness, obvious peculiar smell is felt, and a user is reminded to check and clean out expired food materials possibly; and when the refrigerator runs in the M3 mode, judging that food materials in the refrigerator are deteriorated and rotten, and reminding a user to immediately clean and clean the refrigerator.

Specifically, the method for calculating the initial concentration value comprises the following steps: responding to the first power-on operation of the refrigerator, starting the sterilization and purification device and controlling the sterilization and purification device to work in a preset lowest intensity mode; after the sterilizing and purifying device stops running, acquiring a gas concentration value detected by the odor detection device; when the evaluation parameters input by the user are acquired, calculating the initial concentration value based on the weight value corresponding to the evaluation parameters and the gas concentration value; the evaluation parameters comprise at least two evaluation grades, and each evaluation grade has a corresponding weight value; and when the evaluation parameters input by the user are not acquired, acquiring a default weight value and the gas concentration value to calculate the initial concentration value.

For example, when the refrigerator is powered on for the first time, the sterilizing and purifying device is started and the controller works in a preset minimum intensity mode M0, M0 is smaller than M1, and because the refrigerator is powered on for the first time, the storage room does not store or store less articles, and weak sterilizing operation is started at this time, so that the operating rule of the sterilizing and purifying device can be set by a user for purifying peculiar smell of the refrigerator due to long-term unsealing. There are two ways to obtain the user evaluation parameters, one is obtained through a display screen of the refrigerator, and the other is obtained through a mobile terminal connected in advance with the refrigerator. If the user is prompted to evaluate the refrigerator odor at this time, and no reply is received for a long time, the initial concentration value needs to be calculated by adopting a default mode. Detecting the concentration value of the gas in the air in the refrigerator as P0, acquiring the evaluation of the freshness of the air in the refrigerator by a user, determining an evaluation coefficient K according to the evaluation result, and calculating the initial concentration P0 of the smell in the air in the refrigerator. The evaluation parameters are classified into three grades of excellent, good and general, the corresponding evaluation weight values are respectively 0.5K, K and 1.5K, so that the initial odor concentrations corresponding to the high (H), medium (M) and low (L) odor sensitivities are respectively POH=0.5 KpO, POM=KpO and POL=1.5 KpO. If the refrigerator is powered on for the first time and the evaluation result of the user cannot be obtained, the default weight value is K, and the initial concentration value is pom= KpO at this time.
