[0056] 1 to 2 , some embodiments of the present disclosure provide a refrigerator, wherein the refrigerator 1000 includes a housing 10 defining a storage space. At least one storage chamber 100 is provided in the housing 10, and the storage chamber 100 is configured to store items that require freshness or freezing. The storage chamber 100 can be divided into a refrigeration chamber, a freezer chamber, a temperature-changing chamber, a vacuum chamber, a moisturizing area, and the like, depending on its purpose. For example, three storage chambers 100 are provided in the housing 10, the storage chamber 100 at the upper portion of the housing 10 is a refrigeration chamber, the storage chamber 100 at the lower portion of the housing 10 is a freezer chamber, and the storage chamber 100 in the middle portion of the housing 10 is a temperature-changing chamber.

[0057] In some embodiments, at least one component storage cavity is further provided in the box body 10, such as a press cabin.

[0058] In some embodiments, the refrigerator 1000 further includes a door 20 configured to open and close the storage chambers 100. For example, a receiving opening for taking items in and out is formed on one side of each storage chamber 100, and the door 20 is rotatably mounted on the side of the box body 10 to open or close the receiving opening.

[0059] In some embodiments, one or more doors 20 are provided at the opening of each storage chamber 100. For example, two doors 20 are provided at the opening of the refrigeration chamber.

[0060] 2 , the door 20 includes a door outer shell 210 and a door inner shell 220 , which are disposed opposite to each other. The door outer shell 210 is located outside the box 10 and the door inner shell 220 is located inside the box 10 .

[0061] In some embodiments, the door body 20 further includes an upper end cover 230 and a lower end cover 240 , and the upper end cover 230 is disposed opposite to the lower end cover 240 .

[0062] In some embodiments, the door body 20 further includes an insulation layer, which is located between the door body outer shell 210, the door body inner shell 220, the upper end cover 230, and the lower end cover 240. The insulation layer can be filled with foam.

[0063] In some embodiments, the door body 20 can be pivotally disposed at the opening of the storage chamber 100, and can also be connected to a drawer box in the storage chamber 100 to achieve pull-out opening and closing.

[0064] In some embodiments, the refrigerator 1000 further includes a refrigeration system 200 , which is installed in the housing 10 and configured to cool the storage chamber 100 by controlling a refrigerant.

[0065] 4 , a refrigeration system 200 includes a compressor 1 configured to compress a refrigerant.

[0066] In some embodiments, the refrigeration system 200 further includes a condenser 4 , and the outlet of the compressor 1 is connected to the inlet of the condenser 4 .

[0067] In some embodiments, the refrigeration system 200 further includes a pressure reducer 3 , and an outlet of the condenser 4 is connected to the pressure reducer 3 .

[0068] In some embodiments, refrigeration system 200 further includes an evaporator 2, the inlet of evaporator 2 being connected to pressure reducer 3, and the outlet of evaporator 2 being connected to the inlet of compressor 1. Evaporator 2 can be installed in an evaporation chamber between the casing and the liner. Evaporator 2 is configured to evaporate the refrigerant to absorb heat from the ambient air.

[0069] The working process of the refrigeration system 200 includes a compression process, a condensation process, a throttling process and an evaporation process.

[0070] For example, the compression process includes: the compressor 1 starts working, low-temperature, low-pressure refrigerant is sucked into the compressor 1, compressed into high-temperature, high-pressure superheated gas in the cylinder of the compressor 1, and then discharged into the condenser 4.

[0071] The condensation process involves the high-temperature, high-pressure refrigerant gas dissipating heat through the condenser 4, gradually cooling to a saturated vapor at room temperature and high pressure. It then cools further to a saturated liquid, where the temperature stops falling. This temperature is called the condensation temperature. The refrigerant pressure remains virtually unchanged throughout the condensation process.

[0072] The throttling process includes: the condensed refrigerant saturated liquid is filtered through a drying filter to remove moisture and impurities, and then flows into the pressure reducer 3, and is throttled and depressurized by the pressure reducer 3 to become wet steam at room temperature and low pressure.

[0073] The evaporation process includes: the wet steam at room temperature and low pressure begins to absorb heat and vaporize in the evaporator 2, which not only reduces the temperature of the evaporator 2 and the gas around the evaporator 2, but also turns the refrigerant into a low-temperature and low-pressure gas.

[0074] The refrigerant coming out of the evaporator 2 passes through the gas-liquid separator and then returns to the compressor 1. By repeating the above working process, the heat in the refrigerator 1000 can be transferred to the air outside the box to reduce the temperature in the storage chamber 100.

[0075] Afterwards, if the temperature of the storage chamber 100 is within the preset temperature range, the refrigeration system 200 is turned off. Over time, the temperature of the storage chamber 100 rises. If the temperature of the storage chamber 100 rises outside the preset temperature range, the refrigeration system 200 is turned on again, and the above process repeats. This ensures that the temperature inside the storage chamber 100 fluctuates within the preset temperature range.

[0076] 1 and 2 , the refrigerator 1000 further includes a display device 5 disposed on a side of the refrigerator body 10 facing the user. The display device 5 is configured to display information such as the temperature of the storage compartment 100 and the operating status of the refrigerator 1000, and to receive user input, such as temperature adjustment instructions and operating mode adjustment instructions.

[0077] In some embodiments, each storage compartment 100 corresponds to a corresponding refrigeration duct. Referring to Figures 2 to 4 , taking the refrigerator compartment as an example, the refrigerator 1000 further includes a refrigeration duct 130. The refrigeration duct 130 is disposed between the liner and the outer shell of the refrigerator compartment. The refrigeration duct 130 connects the evaporator compartment, where the evaporator 2 is located, with the refrigerator compartment and is configured to provide cold air to the refrigerator compartment.

[0078] 3 , the refrigerator 1000 further includes a second fan 13. The second fan 13 is disposed in the refrigeration air duct 130 and is configured to accelerate the circulation of air in the refrigeration air duct 130 and the refrigeration chamber.

[0079] 5 , refrigerator 1000 establishes a data connection with client 500 via router 300 or cloud server 400. When refrigerator 1000 and client 500 communicate via router 300, they are relatively close together, allowing a user to check the operating status of refrigerator 1000 or the storage status of food in the kitchen from within the living room or bedroom. When refrigerator 1000 and client 500 communicate via cloud server 400, they are relatively far apart, allowing the user to interact with the refrigerator 1000 through an app installed on the client 500, enabling remote control of the refrigerator 1000.

[0080] In some embodiments, referring to FIG6A , refrigerator 1000 further includes a first detection component 11 , which is disposed within storage compartment 100 and configured to detect the concentration of odorous gases within storage compartment 100 . For example, first detection component 11 is an odorous gas sensor. A gas sensor is a device that converts information such as gas composition and concentration into information that can be used by personnel, instruments, computers, and the like. The odorous gas sensor can detect the concentration of odorous gases in the surrounding area.

[0081] For example, psychrophilic bacteria in refrigerators produce metabolic gases during their growth and metabolism. These gases include volatile compounds with a strong rotten egg smell, such as methane, hydrogen sulfide, methyl mercaptan, and methylamine. An odor gas sensor can determine the concentration of odorous gases in the refrigerator by detecting the concentration of these volatile compounds. Of course, odorous gases other than these volatile compounds may be present in the refrigerator, and this disclosure does not limit the odorous gases that can be detected by the odor gas sensor.

[0082] 6A , the refrigerator 1000 further includes a deodorizing device 12 disposed in the storage chamber 100 and configured to remove odors therein. Referring to FIG2 , the deodorizing device 12 may be disposed on a shelf on a side of the door 20 near the storage chamber 100.

[0083] For example, the odor removal device 12 may include an ozone generator or an ionizer. In this case, the odor removal device 12 can generate ionized gas or ozone through the action of electric charge, releasing a large amount of negative ions, positive ions, or ozone into the air, thereby purifying the air. The odor removal device 12 may include components such as a needle electrode, a grounding ring, a control circuit, and insulation protection.

[0084] It should be noted that the deodorizing device 12 may also be a device other than an ozone generator or an ion generator that can remove the odor of food in the refrigerator 1000, and the present disclosure does not impose any restrictions on this.

[0085] It is understood that placing the first detection assembly 11 and the odor purification device 12 in the storage chamber 100 facilitates the first detection assembly 11 in detecting the concentration of odorous gases in the storage chamber 100 and facilitates the user to repair and replace the first detection assembly 11 and the odor purification device 12. In other embodiments, referring to FIG. 3 , the first detection assembly 11 and the odor purification device 12 may also be placed in the refrigeration air duct 130, which is not limited in this disclosure.

[0086] In some embodiments, referring to FIG6A , the refrigerator 1000 further includes a controller 600. The controller 600 may be a chip or a processor. For example, the processor may be a general-purpose central processing unit (CPU), a microprocessor, or an application-specific integrated circuit (ASIC). Alternatively, the controller 600 may be a programmable device, including a complex programmable logic device (CPLD), an erasable programmable logic device (EPLD), or a field programmable gate array (FPGA). The chip may be an integrated circuit (IC).

[0087] In some embodiments, the controller 600 is coupled to the first detection component 11 to obtain the concentration of the odorous gas detected by the first detection component 11.

[0088] In some embodiments, the controller 600 is further coupled to the odor purification device 12 to control the operation of the odor purification device 12 according to the concentration of the odorous gas.

[0089] Typically, the odor removal device in a refrigerator activates when the concentration of odorous gases exceeds a preset value, and deactivates when the concentration is equal to or less than the preset value. This can easily cause the odor removal device to start and stop repeatedly, shortening its service life. Furthermore, if the odor removal device continues to operate when the concentration of odorous gases exceeds the preset value, it can easily generate excessive ozone, leading to increased ozone concentration inside the refrigerator. Excessive ozone not only corrodes the refrigerator's internal materials but also poses a health risk.

[0090] Furthermore, since refrigerators vary in volume, users have varying degrees of sensitivity to odor. Therefore, if the odor removal device is controlled solely according to a pre-set fixed operating mode for large refrigerators or users with high odor sensitivity, there is a risk that odors may still be present in the refrigerator while the odor removal device has stopped operating, thereby affecting the odor removal effectiveness of the device.

[0091] Some embodiments of the present disclosure provide a refrigerator 1000, which determines the target operating mode of the odor purification device 12 based on the current concentration of odorous gases in the storage chamber 100, and controls the operation of the odor purification device 12 according to the target operating mode. The parameters of the target operating mode include operating phase parameters and idle phase parameters. The operating phase parameters include the on-time and off-time of the odor purification device 12 in a start-stop cycle, and the number of cycles of the start-stop cycle. The idle phase parameters include the idle time of the odor purification device 12. In this way, the repeated start and stop of the odor purification device 12, which leads to a reduction in the service life of the odor purification device 12, is avoided, and the continuous operation of the odor purification device 12 to generate excessive ozone is avoided.

[0092] In addition, the refrigerator 1000 in some embodiments of the present disclosure also adjusts the target operating mode corresponding to the odor purification device 12 according to the volume of the refrigerator and the user's sensitivity to odors, so that the operating mode of the odor purification device 12 can fully remove odors under the current volume of the refrigerator and the current user sensitivity, thereby improving the odor purification effect of the odor purification device 12.

[0093] In some embodiments of the present disclosure, the refrigerator 1000 includes at least one odor-purifying mode. For example, the at least one odor-purifying mode includes a first odor-purifying mode. In the first odor-purifying mode, the controller 600 controls the operating state of the odor-purifying device 12 based on the current concentration of odorous gases within the storage compartment 100. For example, the first odor-purifying mode is an adaptive odor-purifying mode.

[0094] In some embodiments, the controller 600 is configured to: if it is determined that the refrigerator 1000 is in the first odor-purifying mode, obtain the odor gas concentration in the current storage chamber 100, and determine the odor level corresponding to the odor-purifying device 12 based on the obtained odor gas concentration; determine the target operating mode of the odor-purifying device 12 based on the odor level; and control the operation of the odor-purifying device 12 according to the target operating mode.

[0095] It is understood that, referring to Table 1, a mapping relationship between odor gas concentration and odor level is pre-stored in the refrigerator 1000. After obtaining the current odor gas concentration in the storage chamber 100, the controller 600 can determine the odor level corresponding to the current odor gas concentration based on the pre-set mapping relationship between odor gas concentration and odor level.

[0096] In some embodiments, the odor gas concentration is divided into at least two odor levels. For example, in the first odor-free mode, the odor gas concentration detected by the first detection component 11 is divided into three different odor levels from low to high. For example, the odor gas concentration range is [1, X1) for a slight odor level, represented by odor level A. The odor gas concentration range is (X1, X2) for a moderate odor level, represented by odor level B. The odor gas concentration range is (X2, X3) for a high odor level, represented by odor level C. Level A means basically no odor, level B means a slight odor, and level C means an obvious odor. It can be understood that X1 < X2, and X2 < X3.

[0097] Table 1 Odor Grades

[0098] It is understood that, referring to Table 2, the refrigerator 1000 also pre-stores a mapping relationship between odor levels and operating modes of the odor purification device 12. After determining the odor level corresponding to the current odorous gas concentration, the controller 600 can determine the target operating mode of the odor purification device 12 based on the pre-set mapping relationship between odor levels and operating modes of the odor purification device 12.

[0099] In some embodiments, any one of the at least two odor levels corresponds to an operating mode of the odor purification device 12. As shown in Table 1, odor level A corresponds to the first operating mode D, odor level B corresponds to the second operating mode E, and odor level C corresponds to the third operating mode F.

[0100] In some embodiments, in any of at least one operating mode, the operating parameters of the odor purification device 12 include operating phase parameters and idle phase parameters. The operating phase parameters include the on-time and off-time of the odor purification device 12 within an on-off cycle, and the number of on-off cycles. The idle phase parameters include the idle time of the odor purification device 12.

[0101] Table 2 Operation mode of the odor purification device 12 in the first odor purification mode

[0102] In some embodiments, the power-on duration in the on-off cycle satisfies: t1 < t2.

[0103] In some embodiments, the power-on duration in the on-off cycle satisfies: t2 < t3.

[0104] For example, t1 is 10 seconds, t2 is 20 seconds, and t3 is 30 seconds.

[0105] In some embodiments, the number of cycles of the on-off period satisfies: T1 < T2.

[0106] In some embodiments, the number of cycles of the on-off period satisfies: T2<T3.

[0107] For example, T1 is 5 times, T2 is 10 times, and T3 is 15 times.

[0108] In some embodiments, the idle duration of the idle phase satisfies: K3<K2.

[0109] In some embodiments, the idle duration of the idle phase satisfies: K2<K1.

[0110] For example, K3 is 3 minutes, K2 is 2 minutes, and K3 is 1 minute.

[0111] It should be noted that the values ​​of the start-stop cycle, start time, stop time, number of cycles of the start-stop cycle and idle time in Table 2 can be pre-set by empirical values, and this disclosure does not limit this.

[0112] It should be noted that the odor gas concentration is positively correlated with the odor level; the odor level is positively correlated with the startup time; the odor gas concentration is positively correlated with the number of cycles of the start-stop cycle; the odor level is negatively correlated with the shutdown time; and the odor gas concentration is negatively correlated with the idle time.

[0113] That is, as the odor level increases, the on-time within the on-off cycle increases, the off-time within the on-off cycle decreases, and the number of on-off cycles increases while the idle time decreases. Thus, the higher the odor level, the greater the total amount of positive and negative ions or ozone released by the odor purification device 12, thereby improving the odor purification effect and reducing the odor purification time.

[0114] It should be noted that the number of cycles of the start-stop period can be a positive integer greater than or equal to 1, or any decimal greater than zero.

[0115] In some embodiments, the duration of an on-off cycle is set to a fixed value, such as 60 seconds. Of course, the duration of the on-off cycle can also be 100 seconds, 30 seconds, etc. In addition, the duration of the on-off cycle can be different at different odor levels, and the duration of the on-off cycle in two adjacent cycles can also be different at the same odor level. This disclosure does not impose any restrictions on this.

[0116] It should be noted that the setting of the power-on time and the power-off time can not only enable the deodorizing device 12 to fully remove the odor in the storage chamber 100, but also avoid the generation of excessive ozone to a certain extent, which may affect the food and users.

[0117] It's understandable that the idle time (K2) can further prevent excessive ozone levels from being caused by the odor removal device 12 being on for extended periods. For example, if the first detection component 11 malfunctions and mistakenly determines that odor is still present in the storage chamber 100, the ozone generated by the odor removal device 12 during its operating phase will be almost completely degraded within the K2 time, as the odor removal device 12 enters its idle phase after its operating phase. This eliminates the risk of excessive ozone levels by turning the odor removal device 12 back on after the idle phase.

[0118] After determining the target operating mode for the odor-purifying device 12, the controller 600 controls the operation of the odor-purifying device 12 according to the target operating mode. At this point, the odor-purifying device 12 alternates between an operating phase and an idle phase. During the operating phase, the odor-purifying device 12 executes at least one on-off cycle, operating according to a preset on-time duration, Ton, and a preset off-time duration, Toff, within any one of the at least one on-off cycles. That is, the odor-purifying device 12 starts operating for Ton and then stops for Toff, completing an on-off cycle. It then continues operating for Ton and then stops for Toff, repeating the cycle.

[0119] During the operating phase, the controller 600 also obtains the number of on-off cycles executed by the odor purification device 12. If the number of on-off cycles is greater than or equal to the number of on-off cycles T, the operating phase ends and the odor purification device 12 enters the idle phase. During the idle phase, the odor purification device 12 stops operating. After the idle time of the odor purification device 12 is greater than or equal to the preset idle time K, the odor purification device 12 re-obtains the odorous gas concentration within the storage chamber 100.

[0120] It can be understood that if it is determined that the concentration of odorous gas in the storage chamber 100 detected by the first detection component 11 is at level A, it indicates that there is basically no odor in the refrigerator 1000.

[0121] In some embodiments, if the controller 600 determines that the current odor level is A, it can control the odor purification device 12 to operate in the first operating mode D corresponding to the odor level A. After running for T1 on-off cycles, the odor purification device 12 enters the idle phase and re-acquires the odor gas concentration detected by the first detection component 11 after the idle period K1 has elapsed.

[0122] In this way, when there is basically no odor in the refrigerator 1000, the odor purification device 12 is still turned on for odor purification. When there are ingredients in the box 10 whose odor cannot be identified by the first detection component 11, or when the first detection component 11 fails, the odor purification effect of the refrigerator 1000 can be guaranteed.

[0123] In other embodiments, if the controller 600 determines that the current odor level is A, the odor purification device 12 may be controlled to be in a shutdown state. In this way, energy can be saved and the service life of the odor purification device 12 can be extended.

[0124] In some embodiments, if the controller 600 determines that the odor gas concentration detected by the first detection component 11 is at odor level B, it indicates that there is a slight odor in the refrigerator 1000. In this case, the odor purification device 12 is controlled to operate in the second operating mode E corresponding to odor level B. After operating for T2 on-off cycles, the odor purification device 12 enters an idle phase. After the idle period K2 has elapsed, the odor gas concentration detected by the first detection component 11 is re-obtained.

[0125] Similarly, the operation process of the odor purification device 12 in the third operation mode F corresponding to the odor level C is the same as above.

[0126] In some embodiments of the present disclosure, by configuring the on-time and off-time, ozone levels can be controlled within a preset range, preventing the odor removal device 12 from continuously generating large amounts of ozone. This ensures that the odor removal device 12 achieves its odor-removing effect while preventing excessive ozone from affecting food and users. Furthermore, the idle time setting prevents the first detection component 11 from malfunctioning and requiring frequent activation, further preventing ozone levels from exceeding the specified limit.

[0127] In some embodiments, during the entire deodorization process of the deodorization device 12, the counter of the controller 600 counts the number of cycles of the start-stop cycle cumulatively. That is to say, in the operating modes corresponding to all the above-mentioned odor levels, the counter that counts the number of cycles of the start-stop cycle is shared. That is, the first operating mode D, the second operating mode E, and the third operating mode F share the same start-stop cycle counter. For example, the controller 600 first controls the deodorization device 12 to operate in the first operating mode D, and the number of cycles of the first operating mode D is X. During this period, if the controller 600 determines that the odor level has changed to B, it controls the deodorization device 12 to operate in the second operating mode E, and the number of cycles of the second operating mode E is Y. Then, in the above process, the number of cycles of the start-stop cycle recorded by the start-stop cycle counter is X+Y.

[0128] In some embodiments, the controller 600 is further configured to: in the presence of odor level switching, obtain the number of cycles of the start-stop cycle recorded by the start-stop cycle counter; if it is determined that the obtained number of cycles of the start-stop cycle is greater than or equal to the number of cycles of the start-stop cycle preset in the operating mode corresponding to the current odor level, then enter the idle phase in the operating mode corresponding to the current odor level, and control the start-stop cycle counter to be cleared.

[0129] It can be understood that after entering the idle stage, the odor purification device 12 no longer obtains the odor gas concentration detected by the first detection component 11, but waits until the idle stage ends and then re-obtains the odor gas concentration detected by the first detection component 11 to control the odor purification device 12 to enter the next operation stage according to the odor gas concentration.

[0130] In some embodiments, when it is determined that the odor level has changed, the odor level can be switched after waiting for a preset time. If it is determined that the odor gas concentration detected by the first detection component 11 has been at the changed odor level within the preset time, for example, 10 seconds, then it is determined that the odor level has changed. At this time, the controller 600 controls the odor removal device 12 to switch to the corresponding operating mode of the changed odor level. For example, if the controller 600 determines that the odor gas concentration detected by the first detection component 11 at time t has changed from A to B, and if the odor level has been at level B within t+10 seconds, then the operating mode of the odor removal device 12 is controlled to change from D to E.

[0131] In some embodiments, referring to FIG6B , the refrigerator 1000 further includes an information push device 16 configured to push different information to the user. The information push device 16 may be a display device 5, a voice module, an LED light module, or a buzzer provided on the refrigerator 1000. Different information push contents may be configured to convey different information to the user.

[0132] In some embodiments, the controller 600 is further configured to: obtain at least one of the cumulative number of times the odor removal device 12 has operated according to the operating parameters corresponding to the preset maximum odor level, or the cumulative duration of the operation according to the operating parameters corresponding to the preset maximum odor level; and, if either a first preset condition or a second preset condition is met, control the information push device 16 to execute a preset reminder strategy to indicate that the odorous gas concentration in the current storage chamber 100 is continuously abnormal. The first preset condition includes the cumulative number of times being greater than or equal to a preset number threshold, and the second preset condition includes the cumulative operating duration being greater than or equal to a preset duration threshold.

[0133] In some embodiments, when refrigerator 1000 is in the first odor-purifying mode, the number of times odor-purifying device 12 has been run in the operating mode corresponding to the highest odor level (e.g., odor level C in the above embodiment) is obtained. If the cumulative number is determined to be greater than or equal to a preset threshold, it indicates that there is a strong odor in refrigerator 1000 and that odor-purifying device 12 has not been able to effectively remove the odor after multiple runs at the highest level. In this case, it indicates that there may be spoiled food or strongly odorous food left exposed in refrigerator 1000. Since odor-purifying device 12 cannot remove the odor in a short period of time, a corresponding prompt needs to be issued to the user to remind the user to deal with the strongly odorous food in storage chamber 100.

[0134] In other embodiments, the operating time of the deodorizing device 12 in the operating mode corresponding to the highest odor level is obtained. If it is determined that the cumulative operating time is greater than or equal to the preset time threshold, it also indicates that the odor in the refrigerator 1000 is relatively strong, and a prompt message needs to be sent to the user to remind the user to deal with the food with a strong odor in the storage chamber 100.

[0135] The refrigerator 1000 provided in some embodiments of the present disclosure can promptly remind the user to deal with food with a strong odor when the concentration of odorous gas in the refrigerator 1000 remains abnormal, thereby improving the odor purification effect of the refrigerator 1000 and increasing the service life of the odor purification device 12.

[0136] In some embodiments, when the refrigerator 1000 is in the first odor-free mode, the controller 600 is further configured to: receive a sensitivity setting instruction input by the user before obtaining the current odor gas concentration of the storage chamber 100 to determine the corresponding odor level; the sensitivity setting instruction is configured to set the user's sensitivity to odor; according to the user's sensitivity to odor, set an odor gas concentration range corresponding to at least one preset odor level; the threshold range includes an upper limit value and a lower limit value, and the higher the user's sensitivity to odor, the smaller at least one of the upper limit value or the lower limit value of the odor gas concentration corresponding to the odor level.

[0137] It is understood that refrigerator 1000 is pre-set with at least one odor level, with different operating modes corresponding to different odor levels. However, due to differences in the human body, different users have different sensitivities to the same odorous gas concentration. Some embodiments of the present disclosure, by studying the response of the first detection component 11 to different food odors and the sensitivity of the human senses to different food odors, set the odorous gas concentration range corresponding to the at least one odor level based on user sensitivity. Generally, the higher the user's sensitivity to odor, the lower either the upper limit or the lower limit of the odorous gas concentration corresponding to the odor level.

[0138] For example, in the first odor-free mode, three different sensitivity levels are set, namely the first sensitivity (high sensitivity), the second sensitivity (medium sensitivity) and the third sensitivity (low sensitivity). Users can input the sensitivity setting instructions according to their own odor sensitivity through preset human-computer interaction components, such as the display device 5 of the refrigerator 1000 or the mobile terminal APP bound to the refrigerator 1000, so as to set the sensitivity that suits their own senses.

[0139] Referring to Table 3, at any one of at least one sensitivity, the odor gas concentration is divided into three different odor levels, namely A, B and C, according to the output signal of the first detection component 11. Odor level A indicates basically no odor, odor level B indicates a slight odor, and odor level C indicates a clear odor.

[0140] Table 3 Odor gas concentration range corresponding to each odor level at different sensitivities

[0141] It should be noted that the same odor level corresponds to different odor gas concentration ranges under different sensitivities. The higher the sensitivity, the higher at least one of the upper limit or lower limit of the odor gas concentration range can be, that is, the higher the odor concentration threshold for dividing the odor level can be.

[0142] In some embodiments, in the odor concentration threshold corresponding to odor level A, X 31 <X 21 .

[0143] In some embodiments, in the odor concentration threshold corresponding to odor level A, X 21 <X 11 .

[0144] In some embodiments, in the odor concentration threshold corresponding to odor level B, X 32 <X 22 .

[0145] In some embodiments, in the odor concentration threshold corresponding to odor level B, X 22 <X 12 .

[0146] In some embodiments, in the odor concentration threshold corresponding to the odor level C, X 33 <X 23 .

[0147] In some embodiments, in the odor concentration threshold corresponding to the odor level C, X 23 <X 13 .

[0148] In some embodiments, the controller 600 is further configured to: currently obtain the odor gas concentration of the storage chamber 100; and determine the threshold range into which the current odor gas concentration of the storage chamber 100 falls based on the odor gas concentration and the odor gas concentration range corresponding to the at least one odor level, so as to determine the odor level.

[0149] The refrigerator 1000 provided in some embodiments of the present disclosure can better meet the user's demand for odor removal of the refrigerator 1000 by allowing the user to adjust the sensitivity at any time according to his or her own experience.

[0150] In some embodiments, the controller 600 is further configured to: after determining the corresponding odor level, determine the target information push content corresponding to the current odor level according to the preset correspondence between the odor level and the information push content; and control the information push device 16 to perform the corresponding information push operation according to the target information push content.

[0151] In some embodiments, the information push device 16 includes an LED light assembly, such as an LED light bar, which indicates the different odor levels of the refrigerator 1000 through the color and flashing frequency of the LED light. Taking the three odor levels A, B, and C mentioned above as an example, when the odor level is determined to be level A, the light bar is in a solid blue state. When the odor level is determined to be level B, the light bar is in a breathing blue flashing state with a flashing frequency of s1. When the odor level is determined to be level C, the light bar is in a breathing blue flashing state with a flashing frequency of s2, where s2>s1.

[0152] Of course, information push of different odor levels can also be executed through the mobile device APP bound to the refrigerator 1000, and the present disclosure does not impose any restrictions on this.

[0153] The refrigerator 1000 provided in some embodiments of the present disclosure can promptly convey the odor situation in the storage chamber 100 to the user, so that the user can understand the situation and intervene in time.

[0154] In some embodiments, when the refrigerator 1000 is in the first odor-purifying mode, the controller 600 is further configured to: obtain the operating status of the refrigerator 1000 and the open / closed status of the door 20 before obtaining the current odor gas concentration in the storage chamber 100 to determine the corresponding odor level; and control the odor-purifying device 12 to stop operating if either a third preset condition or a fourth preset condition is met. The third preset condition includes the refrigerator 1000 being in the cooling state, and the fourth preset condition includes the door 20 being open.

[0155] That is, if the refrigerator 1000 is in a cooling state, or the door of the refrigerator 1000 is in an open state, the deodorization device 12 is controlled to stop running; if the refrigerator 1000 is not in a cooling state, and the door of the refrigerator 1000 is in a closed state, the current odor gas concentration of the storage room 100 is obtained to determine the corresponding odor level.

[0156] It is understandable that when the refrigerator 1000 is cooling, cold air will blow into the storage chamber 100. When the user opens the door 20, the airflow speed in the storage chamber 100 will increase, affecting the accuracy of the first detection component 11 in detecting the concentration of odorous gases, which may cause the concentration of odorous gases to fluctuate. Therefore, when the refrigerator 1000 is cooling or the door 20 is open, the controller 600 stops receiving signals from the first detection component 11, the odor removal device 12 also stops running, and the current start-stop cycle count is reset. When the refrigerator 1000 detects that the cooling has ended or the door has been closed for a period of time, it receives the signal from the first detection component 11 again, obtains the concentration of odorous gases, and determines the odor level to control the operating status of the odor removal device 12.

[0157] The refrigerator 1000 of some embodiments of the present disclosure can effectively improve the accuracy of the operation control of the deodorizing device 12 and improve the deodorizing effect.

[0158] In some embodiments, the odor-purifying mode of refrigerator 1000 also includes a second odor-purifying mode. In the second odor-purifying mode, controller 600 no longer obtains the odor gas concentration detected by first detection component 11, but instead controls the operation of odor-purifying device 12 solely according to a preset fixed operating mode. For example, the second odor-purifying mode is a forced odor-purifying mode.

[0159] It should be noted that the second odor-purifying mode can be turned on or off based on user instructions. Based on their needs, the user can input a command to activate the second odor-purifying mode through a preset human-computer interaction component, such as the display device 5 of the refrigerator 1000 or a mobile terminal app integrated with the refrigerator 1000, thereby controlling the refrigerator 1000 to enter the second odor-purifying mode. Of course, the user can also input a command to deactivate the second odor-purifying mode through the preset human-computer interaction component, thereby controlling the refrigerator 1000 to enter the first odor-purifying mode.

[0160] In some embodiments, the controller 600 is further configured to: if it is determined that a second odor-purifying mode start-up instruction input by the user is received, then control the refrigerator 1000 to enter the second odor-purifying mode; in the second odor-purifying mode, the odor-purifying device 12 operates according to fixed preset operating parameters; if it is determined that no second odor-purifying mode start-up instruction input by the user is received, then control the refrigerator 1000 to enter the first odor-purifying mode, and obtain the odor gas concentration in the current storage chamber 100 to determine the corresponding odor level.

[0161] In the second odor-purifying mode, the odor-purifying device 12 enters an operating phase and operates according to the preset on-time and off-time corresponding to the second odor-purifying mode during any on-off cycle. After the number of on-off cycles is greater than or equal to the number of on-off cycles corresponding to the second odor-purifying mode, the device stops operating and enters an idle phase. After the idle time in the idle phase is greater than or equal to the preset idle time corresponding to the second odor-purifying mode, the device re-enters the operating phase. For example, the operating modes corresponding to the second odor-purifying mode are shown in Table 4.

[0162] Table 4 Operation mode of the odor purification device in the second odor purification mode

[0163] It should be noted that the second odor-purifying mode is not controlled by the odor gas concentration detected by the first detection component 11. After the user activates the second odor-purifying mode, the controller 600 no longer receives signals from the first detection component 11 until the user exits the second odor-purifying mode and the idle time of the second odor-purifying mode expires. At this point, the controller 600 receives signals from the first detection component 11 and controls the operation of the odor-purifying device 12 based on the odor level.

[0164] Some embodiments of the present disclosure further provide a method for controlling a refrigerator 1000, which can be used to remove odors in the refrigerator 1000. The operating mode of the refrigerator 1000 includes a first odor removal mode. Referring to FIG. 7 , the method includes steps S10 to S30.

[0165] S10: If it is determined that the refrigerator 1000 is in the first odor-free mode, the concentration of the odorous gas in the current storage chamber 100 is obtained to determine the odor level corresponding to the odorous gas concentration.

[0166] S20: Determine a target operating mode for the odor removal device 12 based on the odor level. Parameters of the target operating mode include: the on-time and off-time of any one of at least one on-off cycle within the operating phase, the number of cycles of the on-off cycle, and the idle time of the idle phase.

[0167] S30, control the deodorization device 12 to enter the operation stage, operate according to the preset start-up time and the preset stop time in any of the start-stop cycles, stop running after the number of cycles of the start-stop cycle is greater than or equal to the preset number of cycles of the start-stop cycle, and enter the idle stage, and re-enter the operation stage after the time length of entering the idle stage is greater than or equal to the preset idle time length.

[0168] In some embodiments, referring to FIG. 8 , when the refrigerator 1000 is in the first deodorizing mode, the method includes S11 to S17 .

[0176] In some embodiments, referring to FIG. 9 , before the step ( S10 ) of obtaining the concentration of odorous gas in the current storage chamber 100 to determine the odor level corresponding to the odor concentration if it is determined that the refrigerator 1000 is in the first odor-free mode, the method further includes S31 to S32 .

The threshold range comprises an upper limit and a lower limit. The higher the user's odor sensitivity, the smaller the upper limit and lower limit of the odor gas concentration corresponding to the odor level.

[0179] 9 , after S32 , the controller 600 executes the step ( S10 ) of obtaining the current odor gas concentration in the storage chamber 100 to determine the corresponding odor level. At this time, S10 includes S111 to S121 .

If so, execute S52; if not, execute S111 to obtain the current concentration of odorous gas in the storage chamber 100 to determine the corresponding odor level.

[0198] Referring to Figure 12 , the control method of controller 600 in some embodiments of the present disclosure is described, taking as an example a refrigerator 1000 that includes a first odor-free mode and a second odor-free mode, with the first odor-free mode having three preset odor levels, A, B, and C, and corresponding operating modes. The method comprises steps S71 to S91. The operating process of controller 600 executing this method has been described in detail above and will not be repeated here.

[0199] It should be noted that the implementation process of a control method for a refrigerator 1000 provided in some embodiments of the present disclosure can refer to the control process of the above-mentioned controller 600. The working principles and beneficial effects of the two correspond to each other, and therefore will not be repeated here.

[0200] Some embodiments of the present disclosure provide a refrigerator 1000 and a control method for refrigerator 1000. By determining the operating mode of the odor purification device 12 based on the concentration of odorous gases in the storage compartment 100, the operating intensity of the odor purification device 12 can be effectively controlled according to different odorous gas concentrations. The controller 600 controls the odor purification device 12 to alternate between an operating phase and an idle phase. During the operating phase, the odor purification device 12 cycles through at least one on-off cycle. This not only effectively achieves odor purification, but also prevents the odor purification device 12 from over-operating, extending its service life. Furthermore, when the odor purification device 12 is an ozone generator, it can also prevent excessive ozone concentration from exceeding the specified level, potentially affecting the freshness of food in the refrigerator 1000 and the user's health. Furthermore, this operating mode setting effectively prevents issues such as the odor purification device 12 not operating or over-operating due to the first detection component 11 failing to respond to certain strongly odorous foods or over-responding to others with less odorous foods.

[0201] It should be noted that the odor removal effect of the odor removal device 12 is also affected by the volume of the storage chamber 100. For example, if the current volume of the storage chamber 100 is 400L, and the concentration of the odorous gas detected by the first detection component 11 is at odor level B, the odor removal device 12 operates in accordance with the second operating mode E. Assume that after running for T1 start-stop cycles, the amount of negative ions or ozone generated by the odor removal device 12 is just enough to remove the odor. Then, if the current volume of the storage chamber 100 increases to 500L, and the concentration of the odorous gas detected by the first detection component 11 is also at odor level B, then after the odor removal device 12 runs for T2 start-stop cycles in accordance with the second operating mode E, the amount of negative ions or ozone generated may not be able to completely remove the odor. If there is still an odor in the refrigerator 1000, the odor removal device 12 enters an idle state, thereby affecting the odor removal effect of the refrigerator 1000.

[0202] It is understandable that the larger the volume of the storage chamber 100, the higher the concentration of the odorous gas, and the longer the operation time of the odor removal device 12 can be, so as to generate sufficient negative ions or ozone to ensure the odor removal effect.

[0203] Therefore, the effect of the volume of the refrigerator 1000 on the odor purification effect of the odor purification device 12 is taken into consideration. In some embodiments, after determining the target operating mode of the odor purification device 12, the controller 600 further adjusts the adjustable parameters in the target operating mode according to the volume of the refrigerator 1000 to improve the odor purification effect of the odor purification device 12.

[0204] In some embodiments, the controller 600 is further configured to: obtain the current odorous gas concentration in the storage chamber 100 as detected by the first detection component 11; search for a corresponding target odor level within at least one preset odor level based on the odorous gas concentration; and determine a target operating mode for the odor removal device 12 based on the target odor level, with each odor level corresponding to a corresponding operating mode for the odor removal device 12. The controller 600 also obtains the current volume of the storage chamber 100 and adjusts the adjustable parameters in the target operating mode based on the volume, thereby controlling the operation of the odor removal device 12 according to the adjusted adjustable parameters. In some embodiments, the adjustable parameters include the number of cycles in the on / off cycle of the odor removal device 12. The controller 600 is further configured to: calculate the volume difference between the volume and a preset baseline volume; the baseline volume corresponds to a baseline operating number for at least one odor level; determine an adjustment parameter based on the volume difference; and add the adjustment parameter to the baseline operating number to obtain the target operating number as the adjusted adjustable parameter. The adjustment parameter is positively correlated with the volume difference.

[0205] In some embodiments, the operating mode of the odor removal device 12 can be determined according to Table 2. Referring to Table 2, taking the classification of the odor gas concentration detected by the first detection component 11 into the three odor levels A, B, and C from low to high as an example, the number of operations for odor level A can be less than the number of cycles of the on-off cycle for odor level B, and the number of operations for odor level B can be less than the number of cycles of the on-off cycle for odor level C. An on-off cycle includes a preset on-time period and a preset off-time period.

[0206] In some embodiments, the adjustment process for the number of cycles of the start-stop period can refer to Table 5. It should be noted that the reference volume, reference number of operations, and adjustment parameter values ​​in Table 5 can be pre-set by empirical values, and this disclosure does not limit this.

[0207] Table 5 Number of operation times of the start-stop cycle after superimposing the adjustable parameters

[0208] For example, the reference volume is 100L, and the number of cycles T1, T2, and T3 of the start-stop cycle corresponding to the reference volume are the reference operating numbers of odor levels A, B, and C, respectively.

[0209] As the volume of the storage chamber 100 increases, the adjustment parameters corresponding to the deodorizing device 12 also gradually increase. The adjustment parameters are Y1, 1.5Y1..., Y2, 1.5Y2..., Y3, 1.5Y3..., etc. in the table. Y1, Y2, Y3 can be equal or increase successively. 50*1, 50*2,..., 50*n are the volume differences.

[0210] As the volume increases, the number of on-off cycles of the odor purification device 12 at any odor level also increases according to a certain rule (non-linear). Taking level A as an example: for every 50L increase in volume, the number of on-off cycles will increase accordingly.

[0211] It's understandable that, under the same operating mode, the concentration of negative ions or ozone generated per unit time by the odor-purifying device 12 is fixed, and negative ions and ozone are easily degraded. Therefore, the larger the volume of the storage chamber 100, the lower the probability of negative ions and ozone coming into contact with odor molecules, and the worse the odor-purifying effect of the odor-purifying device 12. Therefore, the greater the increase in the volume of the storage chamber 100 relative to the baseline volume, the more cycles the odor-purifying device 12 needs to operate in. This ensures the odor-purifying effect of the odor-purifying device 12.

[0212] In addition, when the increased volume of the storage chamber 100 is the same, the higher the odor level, the more cycles of the on-off cycle of the odor purification device 12 are increased. In this way, the odor purification effect of the odor purification device 12 can be guaranteed.

[0213] For example, if the volume of the storage chamber 100 increases by 50 L on the basis of the base volume, the number of cycles of the start-stop cycle at level A increases by Y1, and the number of cycles of the start-stop cycle at level B increases by Y2.

[0214] Since the odor level of grade B is greater than that of grade A, the total amount of odor in the refrigerator 1000 under grade B also increases more, so Y2 can be greater than Y1.

[0215] It should be noted that the volume changes in Table 5 are only examples, and the volume of storage compartment 100 may not necessarily be found in the table. If the volume of refrigerator 1000 is within the range specified in Table 5, the number of cycles of the adjusted start-stop cycle can be determined according to the following rules.

[0216] For example, if the storage chamber volume is R, and R satisfies the following conditions: R > (100 + 50 * n) - 25 and R ≤ 100 + 50 * n (n ≥ 1), then the deodorizing device 12 can use the adjustment parameters corresponding to the volume of 100 + 50 * n (n ≥ 1) or the volume of 100 + 50 * (n - 1). Alternatively, the following method can be used: using 50 as a unit, divide R by 50 to obtain a remainder. If the remainder is less than 25, it is discarded. If the remainder is greater than or equal to 25, it is used as 50 to find the closest reference volume from the table.

[0217] For example, if the volume of storage chamber 100 is 238, and the remainder after dividing 238 by 50 is 38, which is greater than 25, then the reference volume of storage chamber 100 is 250. At this time, if the odor level is A, the target number of operations is T1 + 2.5Y1. For another example, if the volume of storage chamber 100 is 218, and the remainder after dividing 218 by 50 is 18, which is less than 25 and can be discarded, then the reference volume of storage chamber 100 is 200. At this time, if the odor level is A, the target number of operations is T1 + 1.5Y1.

[0218] In some embodiments, since different types of refrigerators have different total volumes and the volumes of the storage compartments corresponding to different types of refrigerators are also different, the volumes of the storage compartments 100 in the current refrigerator 1000 may be stored in a database of the refrigerator 1000 before the refrigerator 1000 leaves the factory. In this way, the controller 600 can obtain the volume data pre-stored in the database to determine the volume of the current storage compartment 100.

[0219] It is understood that the control logic in Table 5 may also be pre-stored in the controller 600 of the refrigerator 1000. In this way, after the controller 600 obtains the current volume of the storage chamber 100 through the volume data pre-stored in the database, it can determine the adjustable parameters based on the current volume of the storage chamber 100 and the control logic.

[0220] In some embodiments, the parameters in the operating mode include the number of cycles of the on / off cycle and the idle time of the odor purification device 12. The controller 600 is further configured to: after determining that the odor purification device 12 has completed a target number of operations, control the odor purification device 12 to shut down and enter an idle state; if it is determined that the odor purification device 12 has been in the idle state for a period greater than or equal to the idle time, control the odor purification device 12 to enter the next target number of operations.

[0221] Some embodiments of the present disclosure provide a method for controlling a refrigerator 1000. The method may be executed by the controller 600 or the refrigerator 1000. Referring to FIG. 15 , the method includes steps S100 to S400.

[0222] S100, obtaining the odorous gas concentration in the current storage chamber 100 detected by the first detection component 11.

[0223] S200: Determine a target odor level based on the odor gas concentration and a preset correspondence between the odor gas concentration and the odor level, and obtain a target operating mode of the odor purification device 12 based on the target odor level. Each odor level corresponds to an operating mode of the odor purification device 12.

[0224] S300: Obtain the current volume of the storage room 100.

[0225] S400, adjusting the adjustable parameters in the target operation mode according to the volume, and controlling the operation of the deodorizing device 12 according to the adjusted adjustable parameters.

[0226] In some embodiments, the adjustable parameter includes the number of cycles of the on / off period of the deodorizing device 12. Referring to Figure 16, the step of adjusting the adjustable parameter in the target operation mode according to the volume (S400) includes steps S401 to S403.

[0227] S401: Calculate the volume difference between the volume and a preset reference volume, wherein the reference volume corresponds to at least one reference operation number of different odor levels.

[0228] S402: Obtain a corresponding adjustment parameter according to the volume difference, and add the adjustment parameter to the reference operation times to obtain a target operation times. The adjustment parameter is positively correlated with the volume difference.

[0229] S403, controlling the operation of the deodorizing device 12 according to the target operation times.

[0230] In some embodiments, the parameters in the operation mode include the number of cycles and idle time of the on-off cycle of the deodorizing device 12. Referring to Figure 17, the operation of the deodorizing device 12 is controlled according to the adjusted adjustable parameters (S403), including S4031 to S4034.

[0231] S4031: Determine whether the deodorizing device 12 has completed one operation phase. If yes, execute S4032; if no, execute S4031.

[0232] S4032, control the deodorizing device 12 to stop and enter the idle state.

[0233] S4033: Determine whether the duration of the odor removal device 12 entering the idle state is greater than or equal to the preset idle duration. If so, execute S4034; if not, execute S4032.

[0234] S4034, control the deodorizing device 12 to enter the next operation stage and return to S4031.

[0235] In some embodiments of the present disclosure, the refrigerator 1000 odor purification method employs an odor purification device 12 installed in the storage compartment 100 to purify odors within the refrigerator 1000. During this process, different odor levels correspond to different operating modes of the odor purification device 12. This allows for targeted odor purification methods based on the concentration of odorous gases in the storage compartment 100, thereby improving odor purification effectiveness. Furthermore, the controller 600 acquires the volume of the storage compartment 100 and adjusts the target operating mode accordingly, thereby improving the accuracy of the odor purification logic and further enhancing odor purification effectiveness.

[0236] In some embodiments, the controller 600 is further configured to: obtain the concentration of odorous gas in the storage chamber 100, and determine whether there is an odor in the storage chamber 100 based on the odorous gas concentration; when there is an odor in the storage chamber 100, determine the target odor level corresponding to the odorous gas concentration according to a preset odor level table; the odor level table includes m concentration intervals and corresponding m odor levels, m≥2; determine the target operation mode of the deodorization device 12 based on the volume of the storage chamber 100 and the target odor level, combined with a preset operation strategy table; the operation strategy table includes n volume intervals, m odor levels corresponding to any one of the n volume intervals, and m operation modes, n≥1; control the deodorization device 12 to operate according to the target operation mode. During the operation of the deodorization device 12, if it is determined that the odor level has changed, control the deodorization device 12 to operate according to the operation mode corresponding to the changed odor level until there is no odor in the storage chamber 100.

[0237] The first detection component 11 obtains the concentration of odorous gas in the storage chamber 100, and based on the obtained concentration of odorous gas in the storage chamber 100, determines whether the gas in the storage chamber 100 has an odor. If it is determined that the gas in the storage chamber 100 does not have an odor, the first detection component 11 can be used to obtain the concentration of odorous gas in the storage chamber 100 again, and the determination of whether the gas in the storage chamber 100 has an odor can be re-determined, and corresponding processing can be performed again based on the determination result. If it is determined that the gas in the storage chamber 100 has an odor, a pre-set odor level table is first queried based on the obtained concentration of odorous gas in the storage chamber 100. The odor level corresponding to the odorous gas concentration range corresponding to the odorous gas concentration in the storage chamber 100 is found from the pre-set odor level table, and the found odor level is determined as the target odor level corresponding to the odorous gas concentration in the storage chamber 100.

[0238] Then, based on the volume of the storage chamber 100 and the determined target odor level, the pre-set operation strategy table is queried, and the volume interval corresponding to the volume of the storage chamber 100 is found from the pre-set operation strategy table as the target volume interval. Under the entry corresponding to the target volume interval, the operation mode corresponding to the determined target odor level is found, and the found operation mode is determined as the target operation mode of the deodorization device 12.

[0239] Next, the odor purification device 12 is controlled to operate according to the determined target operating mode. During the operation of the odor purification device 12 according to the determined target operating mode, the first detection component 11 is used to obtain the current odor gas concentration within the storage chamber 100. Based on the current odor gas concentration within the storage chamber 100, a pre-set odor level table is queried to determine the current odor level corresponding to the current odor gas concentration within the storage chamber 100. A determination is then made as to whether the current odor level is the target odor level, that is, whether the odor level of the gas within the storage chamber 100 has changed.

[0240] If it is determined that the current odor level is still the target odor level, it is determined that the odor level of the gas in the storage chamber 100 has not changed. At this time, the odor purification device 12 can continue to be controlled to operate according to the determined target operation mode. If it is determined that the current odor level is not the target odor level, it is determined that the odor level of the gas in the storage chamber 100 has changed. At this time, the pre-set operation strategy table can be queried based on the volume of the storage chamber 100 and the changed odor level to determine the changed operation mode of the odor purification device 12, and the odor purification device 12 can be controlled to operate according to the changed operation mode corresponding to the changed odor level. And so on, until it is determined that the gas in the storage chamber 100 is odorless. Thereby, the purification of the odor in the storage chamber 100 is achieved.

[0241] It should be noted that, in some embodiments of the present disclosure, the controller 600 pre-stores an odor level table and an operation strategy table, so that the corresponding table content can be directly queried when the odor in the storage room 100 is subsequently purified.

[0242] The pre-stored odor level table includes m concentration intervals and odor levels corresponding to the m concentration intervals, with a total of m odor levels, m ≥ 2, and different concentration intervals correspond to different odor levels. The pre-stored operation strategy table includes n volume intervals of storage chambers 100, m odor levels corresponding to the volume intervals of the n storage chambers 100, and operation modes of the deodorization device 12 corresponding to the m odor levels. m odor levels correspond to m operation modes, n ≥ 1. In other words, one volume interval corresponds to m odor levels and m operation modes. Under the entry corresponding to the same volume interval, one odor level corresponds to one operation mode. Different volume intervals can correspond to the same m odor levels, but different volume intervals correspond to different m operation modes, and different odor levels correspond to different operation modes.

[0243] It can be understood that the m odor levels included in the pre-set odor level table do not include the no odor level, that is, these m odor levels are the m odor levels corresponding to when the gas in the storage chamber 100 has an odor, and it is necessary to satisfy m≥2. In this way, it can be ensured that the controller 600 can adjust the odor purification device 12 to operate in different operating modes at different odor levels according to the odor level table to achieve the purpose of odor purification.

[0244] In some embodiments, the first detection component 11 outputs a voltage value to indicate the concentration of the odorous gas. The controller 600 is further configured to: obtain the output voltage value of the first detection component 11; if the output voltage value is determined to be less than a preset first voltage threshold, determine that there is no odor in the storage chamber 100; if the output voltage value is determined to be greater than or equal to the preset first voltage threshold, determine that there is an odor in the storage chamber 100.

[0245] It should be noted that, in some embodiments of the present disclosure, the first detection component 11 indicates the change in the concentration of the odorous gas in the storage chamber 100 by the change in the output voltage value, and the concentration of the odorous gas in the corresponding storage chamber 100 can be determined based on the output voltage value of the first detection component 11. For example, the resistance of the first detection component 11 will change as the concentration of the odorous gas in the storage chamber 100 changes, and the change in resistance causes the change in the output voltage value. Therefore, the concentration of the odorous gas in the storage chamber 100 can be reflected by measuring the change in the output voltage value of the first detection component 11. Accordingly, according to the change in the output voltage value of the first detection component 11, the voltage value can be divided into m voltage intervals, each representing a different concentration interval, that is, corresponding to m odor levels.

[0246] When determining whether the gas in the storage chamber 100 has an odor based on the obtained odorous gas concentration in the storage chamber 100, the output voltage value of the first detection component 11 can be first obtained to determine whether the output voltage value of the first detection component 11 is less than a preset first voltage threshold value V1. If it is determined that the output voltage value of the first detection component 11 corresponding to the odorous gas concentration in the storage chamber 100 is less than the preset first voltage threshold value V1, it is determined that the gas in the storage chamber 100 does not have an odor. If it is determined that the output voltage value of the first detection component 11 is greater than or equal to the preset first voltage threshold value V1, it is determined that the gas in the storage chamber 100 has an odor.

[0247] Referring to Table 6, taking m=3 as an example, odor levels are divided into three corresponding odor levels based on the human sensory sensitivity to odor: slight odor level A, moderate odor level B, and noticeable odor level C. Correspondingly, based on the three voltage limits of the first voltage threshold V1, the second voltage threshold V2, and the third voltage threshold V3, the output voltage value V of the first detection component 11 is divided into three voltage ranges (i.e., corresponding to three concentration ranges).

[0248] When the voltage value V output by the first detection component 11 satisfies V1≤V<V2, the corresponding odor level is slight odor level A. When the voltage value V output by the first detection component 11 satisfies V2≤V<V3, the corresponding odor level is moderate odor level B. When the voltage value V output by the first detection component 11 satisfies V≥V3, the corresponding odor level is obvious odor level.

[0249] It can be understood that when the output voltage value V of the first detection component 11 satisfies V<V1, it is determined that the gas in the storage chamber 100 has no odor.

[0250] Table 6 Odor Grade Table 2

[0251] During operation, when the controller 600 determines the target odor level corresponding to the odorous gas concentration in the storage chamber 100 according to a pre-set odor level table, it may first obtain the output voltage value of the first detection component 11. Referring to Table 6, the controller 600 may compare the output voltage value V of the first detection component 11 with the second voltage threshold V2 and the third voltage threshold V3 (previously determined to be V≥V1) to determine whether the output voltage value V of the first detection component 11 corresponding to the odorous gas concentration in the storage chamber 100 satisfies V1≤V<V2. If V1≤V<V2 is satisfied, the target odor level corresponding to the odorous gas concentration in the storage chamber 100 is determined to be a mild odor level. If V1≤V<V2 is not satisfied, the controller 600 further determines whether the output voltage value V of the first detection component 11 satisfies V2≤V<V3. If V2≤V<V3 is satisfied, the target odor level corresponding to the odorous gas concentration in the storage chamber 100 is determined to be a moderate odor level. If V2≤V<V3 is not satisfied, the output voltage value V of the first detection component 11 corresponding to the odorous gas concentration in the storage chamber 100 is further determined to be V≥V3. If V≥V3 is satisfied, the target odor level corresponding to the odorous gas concentration in the storage chamber 100 is determined to be a noticeable odor level.

[0252] It should be noted that the odor level table shown in Table 6 includes three voltage intervals and three odor levels. It is only an example of the division of odor levels and does not constitute a limitation on the odor levels. The odor level table may include other numbers of voltage intervals and odor levels (for example, m = 2 or 4 or 5, etc.), and the present disclosure does not limit this.

[0253] In some embodiments, the operating mode parameters of the odor removal device 12 include an operating time and an off time. Different operating modes correspond to different operating times, and higher odor levels correspond to longer operating times. Different volume intervals and different odor levels correspond to different operating modes, and the larger the lower limit of the volume interval and the higher the odor level, the higher the operating intensity of the odor removal device.

[0254] It is understandable that the operating intensity can be reflected by the operating time of the deodorizing device 12. Different operating modes correspond to different operating times. The higher the odor level, the longer the corresponding operating time can be. The downtime corresponding to different operating modes can be the same or different. Furthermore, according to the correspondence between the volume interval, the odor level and the operating mode, the larger the lower limit value of the volume interval where the volume value of the storage chamber 100 is located, the higher the odor level, and the longer the corresponding operating time. For example, within the same volume interval, the higher the odor level, the longer the corresponding operating time. Under the same odor level, the larger the lower limit value of the volume interval, the longer the corresponding operating time.

[0255] Refer to Table 7 for a table of operating modes for the odor removal device 12. The three odor levels described above correspond to three different operating modes: Mild odor level A corresponds to the first operating mode, moderate odor level B corresponds to the second operating mode, and significant odor level C corresponds to the third operating mode. The first operating mode has an operating time of t1 and an off time of t0. The second operating mode has an operating time of t2 and an off time of t0. The third operating mode has an operating time of t3 and an off time of t0, with t1 < t2 < t3.

[0256] Table 7 Operation mode table

[0257] It is understandable that if it is determined that the gas in the storage chamber 100 has an odor, the odor removal device 12 can be controlled to operate in different operating modes according to the operating modes shown in Table 7. If it is determined that the gas in the storage chamber 100 has no odor, the odor removal device 12 remains in the shutdown state.

[0258] It should be noted that, when the parameters of the operating mode include operating phase parameters and idle phase parameters, the operating phase parameters include the on-time and off-time of the deodorizing device 12 in a start-stop cycle, and the number of cycles of the start-stop cycle, and the idle phase parameters include the idle time of the deodorizing device 12, the operating time in some embodiments of the present disclosure may refer to the total operating time of the operating phase, or, refer to the on-time of the deodorizing device in the operating phase.

[0259] In some embodiments, the controller 600 is further configured to: control the odor purification device 12 to cyclically operate according to the target operating time and target downtime in the target operating mode; in each cycle, first control the odor purification device 12 to continuously operate for the target operating time, and then control the odor purification device 12 to continuously stop for the target downtime.

[0260] It can be understood that when the controller 600 controls the odor purification device 12 to operate according to the determined target operating mode, it is necessary to control the odor purification device 12 to operate alternately and cyclically according to the target operating time and target downtime included in the determined target operating mode, and in each cycle, the odor purification device 12 is first controlled to operate continuously to reach the target operating time, and then the odor purification device 12 is controlled to stop continuously to reach the target downtime.

[0261] For example, in combination with what is shown in Table 7, when the odor-purifying device 12 is controlled to operate in the second operating mode, it is necessary to control the odor-purifying device 12 to be turned on for t2 seconds, stopped for t0 seconds, turned on for t2 seconds, stopped for t0 seconds, ..., and operate in this cycle until it is determined that the gas in the storage chamber 100 has no odor and the cycle corresponding to the second operating mode is stopped, or until it is determined that the odor level of the gas in the storage chamber 100 has changed, for example, it is determined that the changed operating mode corresponding to the changed odor level is the first operating mode, then the odor-purifying device 12 continues to be controlled to operate in the first operating mode. Similarly, when the odor-purifying device 12 is controlled to operate in the first operating mode, it is necessary to control the odor-purifying device 12 to be turned on for t1 second, stopped for t0 seconds, turned on for t1 second, stopped for t0 seconds, ..., and operate in this cycle until it is determined that the gas in the storage chamber 100 has no odor and the cycle corresponding to the first operating mode is stopped.

[0262] In some embodiments, the i-th volume interval in the operation strategy table is: (i*100-50, i*100+50], and the operation time in the j-th operation mode corresponding to the j-th odor level corresponding to the i-th volume interval is: t j +(k j *(i-1)*(i-2)+1)*R j . t j represents the basic running time corresponding to the jth running mode, k j Indicates the constant coefficient corresponding to the jth operating mode, R j The time increment corresponding to the jth operating mode is represented by (i=2, 3, ..., n) and (j=1, 2, ..., m). The higher the odor level, the larger the corresponding basic operating time, constant coefficient, and time increment.

[0263] Referring to Table 7, the pre-set operation strategy table includes n volume intervals of storage chambers 100, m odor levels corresponding to each volume interval of each storage chamber 100, and m operation modes. When dividing the volume intervals of the storage chambers 100, the volume of the storage chambers 100 can be divided into n volume intervals by setting different volume limits. The endpoint values ​​of the volume intervals are the volume limits. In some embodiments of the present disclosure, for ease of description, these n volume intervals are arranged in ascending order of corresponding volume values. Correspondingly, the m odor levels are also arranged in ascending order of corresponding odorous gas concentrations, and the m operation modes are also arranged in ascending order of corresponding operation times.

[0264] For the i-th volume interval among the n volume intervals of the storage rooms 100 included in the operation strategy table, the interval value range corresponding to the i-th volume interval is: [i*100-50, i*100+50], i=2, 3, ..., n.

[0265] For the jth operating mode corresponding to the jth odor level in the i-th volume interval, the operating time corresponding to the jth operating mode is: t j +(k j *(i-1)*(i-2)+1)*R j . t j represents the basic running time corresponding to the jth running mode, k j Indicates the constant coefficient corresponding to the j-th operating mode, k j Greater than 0, R j Indicates the time increase corresponding to the jth operating mode, R j Greater than 0. The higher the odor level, the greater the corresponding basic operating time, constant coefficient and time increase, that is, it satisfies: t1<t2<…<t j <…<t m , k1<k2<…<k j <…<k m , R1<R2<…<R j <…<R m .

[0266] It should be noted that since i = 2, 3, ..., n, that is, starting from the second volume interval, the interval value range corresponding to each volume interval satisfies (i*100-50, i*100+50], and the running time of each operation mode corresponding to each volume interval satisfies t j +(k j *(i-1)*(i-2)+1)*R j , then when i=1, the interval value range corresponding to the first volume interval is: (0, 150], and the running time of the m running modes corresponding to the first volume interval is set to be the basic running time t1, t2, ..., t j ,…,t m .

[0267] Combining Table 6 and Table 7, the pre-set operation strategy table is shown in Table 8, taking k1=0.25, k2=0.5, k3=0.75 as an example. When i=1, the first volume interval is (0, 150], the operating time in the first operating mode corresponding to the slight odor level is the basic operating time t1, the operating time in the second operating mode corresponding to the moderate odor level is the basic operating time t2, and the operating time in the third operating mode corresponding to the obvious odor level is the basic operating time t3. When i=2, 3, ..., n, the i-th volume interval satisfies (i*100-50, i*100+50], the operating time in the first operating mode corresponding to the slight odor level A satisfies t1+(0.25*(i-1)*(i-2)+1)*R1, the operating time in the second operating mode corresponding to the moderate odor level B satisfies t2+(0.5*(i-1)*(i-2)+1)*R2, and the operating time in the third operating mode corresponding to the obvious odor level C satisfies t3+(0.75*(i-1)*(i-2)+1)*R3.

[0268] Table 8 Operation strategy table

[0269] In the first operating mode, the controller 600 operates as follows: The first detection component 11 obtains the odorous gas concentration within the storage chamber 100, and based on the obtained odorous gas concentration within the storage chamber 100, determines whether the gas within the storage chamber 100 has an odor. If it is determined that the gas within the storage chamber 100 does not have an odor, the first detection component 11 is used to obtain the odorous gas concentration within the storage chamber 100 again, and the determination of whether the gas within the storage chamber 100 has an odor is re-evaluated, and appropriate processing is performed again based on the determination result. If it is determined that the gas within the storage chamber 100 has an odor, Table 6 is first consulted based on the obtained odorous gas concentration within the storage chamber 100. From Table 6, it is determined that the odor level corresponding to the concentration range corresponding to the odorous gas concentration within the storage chamber 100 is a slight odor level. Then, based on the volume of the storage chamber 100 and the determined slight odor level, query Table 7 and find out from Table 7 that the volume interval corresponding to the volume of the storage chamber 100 is (150, 250]. Under the entry corresponding to (150, 250), find out that the operating mode corresponding to the determined slight odor level A is the first operating mode, and the operating time in the first operating mode is t1+R1. Then, control the odor purification device 12 to cyclically operate according to the determined first operating mode, that is, control the odor purification device 12 to cyclically operate according to the rule of turning on for t1+R1 seconds, stopping for t0 seconds, turning on for t1+R1 seconds, and stopping for t0 seconds, until it is determined that the gas in the storage chamber 100 is odorless, and then stop the cycle corresponding to the first operating mode, at which time the purification process ends.

[0270] In the second operating mode, the controller 600 operates as follows: The first detection component 11 obtains the odorous gas concentration within the storage chamber 100, and based on the obtained odorous gas concentration within the storage chamber 100, determines whether the gas within the storage chamber 100 has an odor. If it is determined that the gas within the storage chamber 100 does not have an odor, the first detection component 11 can be used to obtain the odorous gas concentration within the storage chamber 100 again, and the determination of whether the gas within the storage chamber 100 has an odor can be re-evaluated, and corresponding processing can be performed again based on the determination result. If it is determined that the gas within the storage chamber 100 has an odor, Table 6 is first consulted based on the obtained odorous gas concentration within the storage chamber 100. From Table 6, the odor level corresponding to the concentration range corresponding to the odorous gas concentration within the storage chamber 100 is found to be a moderate odor level. Then, according to the volume of the storage chamber 100 and the determined moderate odor level, query Table 7, find out from Table 7 that the volume interval corresponding to the volume of the storage chamber 100 is (0, 150], and under the entry corresponding to (0, 150], find out that the operating mode corresponding to the determined moderate odor level is the second operating mode, and the operating time in the second operating mode is t2. Then, control the odor purification device 12 to cyclically operate according to the determined second operating mode, that is, control the odor purification device 12 to cyclically operate according to the rule of turning on for t2 seconds, stopping for t0 seconds, turning on for t2 seconds, and stopping for t0 seconds, and in the process of the odor purification device 12 cyclically operating according to the determined second operating mode, obtain the current odor gas concentration in the storage chamber 100 through the first detection component 11, and query Table 6 according to the current odor gas concentration in the storage chamber 100 to determine the current odor level corresponding to the current odor gas concentration in the storage chamber 100, and judge whether the current odor level is the moderate odor level, that is, judge whether the odor level of the gas in the storage chamber 100 is moderate. No change. If it is determined that the current odor level is the moderate odor level, it is determined that the odor level of the gas in the storage chamber 100 has not changed. At this time, the deodorization device 12 can continue to be controlled to circulate according to the determined second operating mode. If it is determined that the current odor level is not the moderate odor level, it is determined that the odor level of the gas in the storage chamber 100 has changed. Assuming that the odor level changes from the moderate odor level to the slight odor level, at this time, Table 7 can be re-queried according to the volume of the storage chamber 100 and the changed odor level. Under the entry corresponding to (0, 150], it is found that the operating mode corresponding to the slight odor level is the first operating mode, and the operating time in the first operating mode is t1. Then the deodorization device 12 is controlled to circulate according to the determined first operating mode, that is, the deodorization device 12 is controlled to circulate according to the rule of turning on for t1 seconds, stopping for t0 seconds, turning on for t1 seconds, and stopping for t0 seconds. When it is determined that the gas in the storage chamber 100 has no odor, the cycle corresponding to the first operating mode is stopped, and the purification process ends at this time.

[0315] It can be understood that when it is determined that the current concentration of odorous gas in the storage room 100 is at a severe odor level, the method is similar to the above method and will not be repeated here.

[0316] In summary, some embodiments of the present disclosure provide a refrigerator 1000 and a control method for refrigerator 1000, including a first detection component 11 and an odor purification device 12. The controller 600 determines a target odor level based on the concentration of odorous gases within the storage chamber 100. Based on the volume of the storage chamber 100 and the target odor level, and in conjunction with a pre-set operation strategy table, the controller 600 determines a target operating mode for the odor purification device 12 and controls the odor purification device 12 to operate according to the determined target operating mode. This improves odor purification effectiveness while reducing the risk of ozone generation by the odor purification device 12.

[0317] Currently, related technologies primarily rely on ozone, ultraviolet light, and ion sterilization to achieve odor removal. However, when using these technologies for odor removal, if the refrigerator is continuously running to remove odors, excessive ozone is likely to be generated. High concentrations of ozone not only accelerate the aging of various plastic components in the refrigerator but are also harmful to human health.

[0318] Some embodiments of the present disclosure also provide a refrigerator 1000, which can slowly release odor-purifying substances such as active oxidizing substances to replace ozone to purify odors in the refrigerator 1000, and can also control the release rate of the odor-purifying substances according to the concentration of the odor-purifying substances to improve the flexibility of releasing the odor-purifying substances, thereby improving the accuracy of odor purification.

[0319] In some embodiments of the present disclosure, referring to FIG. 25 , the odor removal device 12 includes an odor removal component 121. For example, odor removal component 121 includes a slow-release catalyst block. Odor removal component 121 is configured to release a target gas capable of removing odors from the refrigerator compartment, replacing ozone to remove odors from refrigerator 1000. This prevents the production of ozone during the odor removal process, thereby preventing ozone from accelerating the aging of various plastic components within refrigerator 1000 and potentially harming human health.

[0320] 27 , the first detection component 11 may be disposed at the air inlet of the deodorizing device 12 to detect the odor concentration in the storage chamber 100 .

[0321] It should be noted that the present disclosure does not limit the type of target gas. For example, the target gas can be any active oxidizing substance capable of removing odors, such as herbal extracts (e.g., eucalyptus oil, lemon oil). In some embodiments, the target gas capable of purifying odors within the housing 10 can also be referred to as the functional component or odor-removing substance of the odor-removing component 121.

[0322] In some embodiments, the odor removal device 12 further includes a heating component 122. The heating component 122 can also be connected to the odor removal component 121 to heat the odor removal component 121. For example, the heating component 122 can be any component such as a heating wire whose heating temperature can be controlled by the controller 600, and this disclosure is not limited to this.

[0323] In some embodiments, the odor removal device 12 further includes a second detection component 123. The second detection component 123 is configured to detect the concentration of the target gas. For example, the second detection component 123 is a slow-release first detection component.

[0324] In some embodiments, the heating component 122 and the second detection component 121 can both be coupled to the controller 600 .

[0325] In some embodiments, the odor removal device 12 further includes a housing 120, and the odor removal component 121, the heating component 122, and the second detection component 123 are all disposed in the housing 120. A card slot is also provided in the housing 120, and the odor removal component 121 can be disposed in the card slot.

[0326] It is understood that the present disclosure does not limit the number of odor purification devices 12 included in the housing 10, nor the number of heating components 122 and odor purification components 121 included in the odor purification device 12. The housing 10 may be the refrigerator compartment or freezer compartment of the refrigerator 1000. The present disclosure also does not limit the connection method between the heating component 122 and the second detection component 121 and the controller 600.

[0327] In some embodiments, the controller 600 is further configured to obtain the concentration of the target gas and control the heating component 122 to heat the deodorizing component 121 according to the concentration of the target gas.

[0328] It is understood that the concentration of the target gas can be used to represent the residual amount of the target gas in the odor removal component 121. For example, the concentration of the target gas can be positively correlated with the residual amount of the target gas in the odor removal component 121. In other words, the greater the residual amount of the target gas in the odor removal component 121, the greater the concentration of the target gas. The less the residual amount of the target gas in the odor removal component 121, the lower the concentration of the target gas.

[0329] First, the controller 600 obtains the concentration of the target gas detected by the second detection component 123. For example, the second detection component 123 periodically collects the concentration of the target gas and sends the collected target gas concentration to the controller 600. Accordingly, the controller 600 can receive the target gas concentration. Alternatively, the controller 600 can also send a gas concentration detection instruction to the second detection component 123, causing the second detection component 123 to respond to the instruction and detect the concentration of the target gas.

[0330] The release rate of the target gas from the odor removal component 121 may be related to the temperature of the heating component 122. For example, the release rate of the target gas from the odor removal component 121 may be positively correlated with the temperature of the heating component 122. In other words, the higher the temperature of the heating component 122, the faster the release rate of the target gas from the odor removal component 121. The lower the temperature of the heating component 122, the slower the release rate of the target gas from the odor removal component 121.

[0331] As mentioned above, since the heating component 122 is connected to the odor removal component 121, the controller 600 can control the temperature at which the heating component 122 heats the odor removal component 121 by adjusting the temperature of the heating component 122. For example, the controller 600 controls the heating power of the heating component 122 based on the concentration of the target gas, thereby controlling the temperature of the heating component 122 and, in turn, controlling the release rate of the target gas from the odor removal component 121. The greater the heating power of the heating component 122, the higher the temperature of the heating component 122 can be. The lower the heating power of the heating component 122, the lower the temperature of the heating component 122 can be.

[0332] For example, when the odor-purifying component 121 is not heated, the higher the concentration of the target gas, the more residual odor-purifying substances in the odor-purifying component 121. The controller 600 can then control the heating component 122 to shut down or lower its temperature to reduce the release rate of the target gas from the odor-purifying component 121, thereby saving the amount of target gas used in the odor-purifying process. When the odor-purifying component 121 is not heated, the lower the concentration of the target gas, the less residual target gas in the odor-purifying component 121. The controller 600 can then control the heating component 122 to increase its temperature to increase the release rate of the target gas from the odor-purifying component 121, thereby ensuring that a sufficient amount of target gas can be released to achieve the odor-purifying effect.

[0333] In some embodiments of the present disclosure, a second detection component 123 is provided in the odor removal device 12 to detect the concentration of the target gas. Based on the target gas concentration, the heating power of the heating component 122 connected to the odor removal component 121 is adjusted, thereby adjusting the rate at which the odor removal component 121 releases the target gas. This increases the flexibility of the target gas release, thereby improving the accuracy of odor purification and reducing the waste of the target gas while ensuring the odor removal effect.

[0334] In some embodiments, the controller 600 is further configured to: determine the concentration of the odorous gas in the box 10 before controlling the heating component 122 to heat the odor-purifying component 121 according to the concentration of the target gas; and control the heating component 122 to heat the odor-purifying component 121 according to the concentration of the odorous gas and the concentration of the target gas.

[0335] For example, the controller 600 may first determine the relationship between the concentration of the target gas and the first preset concentration and the second preset concentration. The first preset concentration and the second preset concentration may be pre-stored in the controller 600. The first preset concentration may be smaller than the second preset concentration.

[0336] If the concentration of the target gas is greater than or equal to the first preset concentration and less than the second preset concentration, it means that the odor-purifying component 121 has consumed part of the odor-purifying substance, that is, the concentration of the target gas released by the odor-purifying component 121 will decrease relative to the initial state, and therefore the odor-purifying effect of the odor-purifying component 121 will also decrease. Therefore, the controller 600 can determine the first preset power of the heating component 122 according to the concentration of the odorous gas in the box body 10, and control the heating component 122 to heat the odor-purifying component 121 according to the first preset power. The first preset power of the heating component 122 can be positively correlated with the concentration of the odorous gas in the box body 10. That is, the greater the concentration of the odorous gas in the box body 10, the greater the first preset power of the heating component 122 can be. The smaller the concentration of the odorous gas in the box body 10, the smaller the first preset power of the heating component 122 can be.

[0337] If the concentration of the target gas is greater than or equal to the second preset concentration, it means that the function of the odor-purifying component 121 meets the odor-purifying requirements, that is, the remaining amount of the odor-purifying substance is sufficient. Therefore, the controller 600 can determine the second preset power of the heating component 122 according to the odor gas concentration in the box body 10, and control the heating component 122 to heat the odor-purifying component 121 according to the second preset power. The second preset power of the heating component 122 can be positively correlated with the odor gas concentration in the box body 10. In other words, the greater the odor gas concentration in the box body 10, the greater the second preset power of the heating component 122 can be. The smaller the odor gas concentration in the box body 10, the smaller the second preset power of the heating component 122 can be.

[0338] It should be noted that, given the same concentration of odorous gas within the housing 10, the second preset power corresponding to the heating component 122 is lower than the first preset power. The lower the power of the heating component 122, the lower the temperature of the heating component 122, and the lower the effect of increasing the release rate of the target gas when the heating component 122 heats the odor removal component 121.

[0339] In this way, the setting of the first preset concentration and the second preset concentration can further improve the accuracy of controlling the heating power of the heating component 122, thereby improving the odor removal effect. When the concentration of the odorous gas in the housing 10 is the same, the greater the concentration of the target gas, the lower the heating power of the heating component 122, and the lower the effect of increasing the release rate of the target gas when the odor removal component 121 is heated by the heating component 122. The lower the concentration of the target gas, the higher the heating power of the heating component 122, and the higher the effect of increasing the release rate of the target gas when the odor removal component 121 is heated by the heating component 122.

[0340] When the controller 600 determines the first preset power or the second preset power of the heating component based on the odorous gas concentration within the housing 10, for example, it may determine the corresponding first preset power or second preset power based on the odorous gas concentration within the housing 10 and a mapping relationship between odorous gas concentration and heating power. It will be understood that the mapping relationship between odorous gas concentration and heating power used to determine the first preset power is different from the mapping relationship between odorous gas concentration and power used to determine the second preset power.

[0341] Referring to Table 9, a mapping relationship between odor levels and heating power of the heating assembly 122 at different target gas concentrations is shown, using the example of categorizing the odor gas concentration within refrigerator 1000 into different levels (e.g., levels A, B, and C, where the odor gas concentration of level A is lower than that of level B, which is lower than that of level C). The controller 600 can determine the second preset power or the first preset power of the heating assembly 122 using Table 9.

[0342] Table 9 Heating power of heating components

[0343] It should be noted that, under the same target gas concentration range, W1'<W2', and W2'<W3'; W1<W2, and W2<W3. Under the same level of odor gas concentration, W1'<W1, W2'<W2, and W3'<W3.

[0344] For example, if the concentration of the target gas is greater than or equal to the second preset concentration, and the odor level corresponding to the odor gas concentration in the box 10 is B, the controller 600 can determine that the power of the heating component 122 is the second preset power W2 ′.

[0345] In some embodiments, if the concentration of the target gas is less than a first preset concentration, it indicates that the odor-purifying substance in the odor-purifying component 121 has been completely consumed and that the odor-purifying component 121 or the entire odor-purifying device 12 needs to be replaced. The controller 600 can then output a prompt message prompting the user to replace the odor-purifying device 12. In this way, the user can promptly receive a prompt message indicating that the odor-purifying substance has been completely consumed and can then promptly replace the odor-purifying device 12, thereby ensuring the odor-purifying effect within the refrigerator 1000.

[0346] For example, the controller 600 may display the above prompt information through the display device 5. Alternatively, the refrigerator 1000 may further include an indicator light configured to indicate that the odor-purifying substance in the odor-purifying component 121 has been consumed. The controller 600 may output the above prompt information by lighting the indicator light.

[0347] Furthermore, in some embodiments, if the controller 600 determines that the odor purification device 12 or the odor purification component 121 has not been replaced within the preset time period of the refrigerator 1000 outputting the above-mentioned prompt information (for example, if the concentration of the target gas is always less than the first preset concentration within the preset time period, it can be determined that the odor purification device 12 or the odor purification component 121 has not been replaced), the controller 600 may no longer control the operation of the odor purification device 12 after the preset time period until the user replaces the odor purification device 12, and then turn on the heating component 122 to adjust the release rate of the target gas.

[0348] 28 , in some embodiments, the odor removal device 12 further includes a first blower 124 . The first blower 124 is configured to accelerate the flow of the target gas. The first blower 124 can be coupled to a controller 600 . It should be noted that this disclosure does not limit the number or location of the first blowers 124 included in the odor removal device 12 .

[0349] In some embodiments, the controller 600 is further configured to obtain the concentration of the odorous gas in the box 10 and adjust the rotation speed of the first fan 124 according to the concentration of the odorous gas in the box 10.

[0350] For example, the controller 600 determines the rotational speed of the first fan 124 based on the concentration of the odorous gas in the housing 10 and the mapping relationship between the odor level to which the odorous gas concentration belongs and the rotational speed of the first fan 124, and controls the first fan 124 to operate at this rotational speed. The rotational speed of the first fan 124 can be positively correlated with the concentration of the odorous gas in the housing 10. In other words, the greater the concentration of the odorous gas in the housing 10, the greater the rotational speed of the first fan 124, and the faster the flow rate of the target gas, thereby reducing the odor in the housing 10 as quickly as possible. The lower the concentration of the odorous gas in the housing 10, the lower the rotational speed of the first fan 124, thereby saving energy.

[0351] In some embodiments of the present disclosure, the flow rate of the target gas is controlled by providing a first fan 124. The rotation speed of the first fan 124 is controlled by obtaining the concentration of the odorous gas within the housing 10, thereby improving the accuracy of the rotation speed control of the first fan 124 and further improving the accuracy of odor removal.

[0352] The timing at which the controller 600 obtains the concentration of the target gas will be described in detail below.

[0353] In some embodiments, the controller 600 is further configured to: in response to an instruction to stop the first fan 124, control the heating component 122 to heat the deodorizing component 121 according to a third preset power; after the first preset time, the controller 600 can control the heating component 122 to stop running, and obtain the concentration of the target gas through the second detection component 123.

[0354] The third preset power and the first preset duration may be pre-stored in the controller 600. The instruction to stop the first fan 124 may be generated by the controller 600 when the rotation speed of the first fan 124 is zero, for example.

[0355] In this way, before performing the operation of obtaining the concentration of the target gas, the first fan 124 is controlled to stop running, which prevents the first fan 124 from blowing away the target gas, improves the accuracy of detecting the concentration of the target gas, and further improves the accuracy of subsequently controlling the release rate of the target gas according to the concentration of the target gas, thereby improving the accuracy of odor removal.

[0356] After the first fan 124 stops running and the heating component 122 heats the odor removal component 121 for a first preset period of time, the operation of obtaining the concentration of the target gas is performed, so that the odor removal component 121 can release a portion of the target gas, so that the controller 600 can detect the concentration of the target gas, thereby further improving the accuracy of odor removal.

[0357] In some embodiments, the controller 600 is further configured to: after controlling the rotation speed of the first fan 124 according to the concentration of the odorous gas in the box body 10, and controlling the heating component 122 to heat the odor purification component 121 according to the concentration of the target gas, determine whether the concentration of the odorous gas in the box body 10 is reduced to below the target odorous gas concentration value.

[0358] For example, if the odor gas concentration in the box body 10 is still greater than the target odor gas concentration value within the second preset time period after the rotation speed of the first fan 124 is controlled according to the odor gas concentration in the box body 10, and the heating component 122 is controlled to heat the odor purification component 121 according to the target gas concentration, the controller 600 controls the first fan 124 to stop running and controls the heating component 122 to stop heating, so as to reduce the consumption of odor purification substances and save energy.

[0359] Then, after waiting for the third preset time, the controller 600 again controls the rotation speed of the first fan 124 according to the concentration of the odorous gas in the box 10, and controls the heating component 122 to heat the odor-purifying component 121 according to the concentration of the target gas.

[0360] It should be noted that the second preset time length, the third preset time length and the target odorous gas concentration value can be pre-stored in the controller 600.

[0361] Through the above embodiment, the heating component 122 can intermittently accelerate the rate at which the odor-purifying component 121 releases the target gas, thereby reducing the consumption of odor-purifying substances while ensuring the purification effect of odors in the refrigerator 1000.

[0362] Referring to Figure 29 , the odor removal device 12 includes two heating assemblies 122 and two odor removal assemblies 121. For example, the two heating assemblies 122 are disposed on opposite sides of the housing 120 along the X-direction. One of the two odor removal assemblies 121 is connected to the heating assembly 122 located on one side of the housing 120 along the X-direction, and the other of the two odor removal assemblies 121 is connected to the heating assembly 122 located on the other side of the housing 120 along the X-direction.

[0363] In some embodiments, the odor purification device 12 may further include at least one damper 125. For example, the odor purification device 12 may include two dampers 125, which may be disposed on both sides of the housing 120 along the Y direction.

[0364] In some embodiments, the shell 120 can form a sealed cavity, and the gas in the storage chamber 100 enters the cavity through the damper 125 located on one side of the shell 120 along the Y direction, and after being deodorized by the deodorizing component 121, flows out from the damper 125 located on the other side of the shell 120 along the Y direction.

[0365] 2, 31 and 32, the odor removal device 12 further includes a first buckle 126. The odor removal device 12 can be fixed in the housing 10 by the first buckle 126. The odor removal component 121 can be a porous slow-release block to facilitate the release of the target gas.

[0366] In some embodiments, the odor purification device 12 further includes a second buckle 127 , and the odor purification component 121 can be fixed in the housing 120 via the second buckle 127 .

[0367] In combination with the deodorizing device 12 shown in Figures 29 to 32, the deodorizing process of the refrigerator 1000 provided in some embodiments of the present disclosure is exemplarily described below.

[0368] In some embodiments, based on the response of the first detection component 11 to the odors of different food ingredients and the human senses' perception of the odors of different food ingredients, the odor gas concentration is classified into three different odor levels based on the output signal of the first detection component 11. For example, [1, X1] is Level A, [X1, X2] is Level B, and [X2, X3] is Level C. Level A indicates essentially no odor, Level B indicates a slight odor, and Level C indicates a noticeable odor.

[0369] If the controller 600 determines that the odor level in the refrigerator 1000 is Class A, the odor purification device 12 is controlled to be in a shutdown state. At this time, the controller 600 starts timing. If the cumulative shutdown time is greater than or equal to the preset shutdown time, the odor purification device 12 is controlled to operate in the following mode. The heating component 122 operates at a power of W1 to heat the odor purification component 121. (It can be understood that since the cold storage room is in a low temperature environment for a long time, and the low temperature environment will reduce the sustained release rate of the odor purification substance in the odor purification component 121, in order to ensure the odor purification effect, the odor purification component 121 can be heated to accelerate the sustained release rate of the odor purification substance.) In addition, the damper 125 is opened, and the first fan 124 is controlled to operate at a speed of R1 to quickly diffuse the target gas slowly released from the odor purification substance into the cold storage room to perform odor purification. After the first preset cumulative operation time, the controller 600 closes the damper 125, the first fan 124 and the heating component 122. During the above process, the first detection component 11 is still running to detect the concentration of odorous gas in the refrigerator 1000. If the controller 600 determines that the odor level corresponding to the odorous gas concentration in the refrigerator 1000 is still at level A, the above process is run again after a time interval T0.

[0370] If the controller 600 determines that the odor level in the refrigerator 1000 is level B, the odor purification device 12 is controlled to operate in the following mode: the heating component 122 operates at a power of W2 to heat the odor purification component (W1 < W2. Since the concentration of odorous gas is greater at level B than at level A, more target gas needs to be slowly released for odor purification. In this case, the heating power of the heating component 122 needs to be increased). In addition, the damper 125 is opened and the first fan 124 is controlled to operate at a speed of R2 (R1 < R2) to increase the gas flow rate in the odor purification device 12, quickly diffusing the slowly released target gas into the refrigerator compartment for odor purification, thereby improving the odor purification efficiency.

[0371] During the above process, the first detection assembly 11 remains in operation to detect the concentration of odorous gases within refrigerator 1000. If the controller 600 determines that the odor level within refrigerator 1000 remains at Level B, it then operates according to the above procedure for a second preset time, then shuts down damper 125, first fan 124, and heating assembly 122. If the controller 600 determines that the odor level within refrigerator 1000 has dropped to Level A, it controls damper 125, first fan 124, and heating assembly 122. At this point, a timer begins. If the odor level remains at Level A within the timer, after a time interval T0, the system resumes operation in the operating mode corresponding to Level A. If the odor level rises to Level C during the timer, the system resumes operation in the operating mode corresponding to Level C. If the odor level remains at Level B within the second preset time, the odor removal device 12 stops operating after the second preset timer has run. After a time interval T0, the odor level within refrigerator 1000 is re-determined.

[0372] If the controller 600 determines that the odor level in the refrigerator 1000 is level C, the odor purification device 12 is controlled to operate in the following mode: the heating component 122 operates at a power of W3 to heat the odor purification component (W1<W2<W3). In addition, the damper 125 is opened, and the first fan 124 is controlled to operate at a speed of R3 (R1<R2<R3), so that the slowly released target gas is quickly diffused into the refrigerator compartment for odor purification, so as to improve the odor purification efficiency. During the above process, the first detection component 11 remains in operation to detect the odor level in the refrigerator 1000. If the odor level is always at level C, the damper 125, the first fan 124 and the heating component 122 are closed after the third preset time is accumulated according to the above procedure. If the odor level is at level B, the odor purification device 12 is controlled to operate in the operating mode corresponding to level B. If the concentration of odorous gas remains at level B within the second preset time, the controller 600 stops running after the deodorizing device 12 runs for the second preset time, and re-determines the odor level in the refrigerator 1000 after an interval of T0.

[0373] It should be noted that the three operating modes corresponding to levels A, B, and C share the same timer to count the operating time of the odor removal device 12. In the event of an odor level switch, as long as the accumulated operating time is greater than or equal to the operating time requirement corresponding to the current level, T0 is immediately reset.

[0374] Since the odor-removing component 121 is a consumable item, varying the sustained-release rate for different odorous gas concentrations can extend the lifespan of the odor-removing component 121. If the concentration of the active ingredient in the odor-removing substance decreases or is completely consumed, the odor-removing effectiveness of the odor-removing component 121 will decrease or even disappear. In this case, a message may be displayed reminding the user to replace the odor-removing device 121.

[0375] In some embodiments, since the concentration of the active ingredient of the odor-purifying substance decreases over time, the odor-purifying effect of the odor-purifying device 12 per unit time will also decrease significantly. Therefore, in this case, the controller 600 can remove the odor as quickly as possible through the following control process.

[0376] When the odor-purifying device 12 is inactive and the damper 125 is closed, the controller 600 assesses the lifespan of the odor-purifying component 121 or the remaining amount of odor-purifying material. The heating component 122 is turned on and operates at a power of W0, promoting the release of slow-release gas into the odor-purifying device 12. After a time period of t, the heating component 122 stops operating. At this point, the slow-release first detection component 11 begins operating to detect the concentration of slow-release gas within the odor-purifying device 12.

[0377] If it is determined that the concentration of the slow-release gas satisfies Y2≤Y<Y3, it indicates that the function of the deodorizing component 121 meets the deodorizing requirement of the refrigerator 1000, and the controller 600 continues to operate in the above-mentioned operating mode.

[0378] If the concentration of the slow-release gas satisfies Y1≤Y<Y2, it indicates that the odor-purifying component 121 has consumed some of the odor-purifying material, and therefore the odor-purifying effect of the odor-purifying component 121 will be reduced compared to its original state. In this situation, if the odor-purifying device 12 is operated again, the following control is implemented: If the controller 600 determines that the odor level is A, the corresponding operating mode of the odor-purifying device 12 remains unchanged. If the controller 600 determines that the odor level is B, the power of the heating component 122 is increased from W2 to W3 during operation. This allows the heating component 122 to increase the amount of target gas released per unit time by the odor-purifying component 121, compensating for the reduced amount of target gas slow-released per unit time caused by the decrease in the total active ingredient content, thereby improving the odor-purifying effect in this situation. Similarly, if the odor-purifying device 12 determines that the odor level is C, the power of the heating component 122 is increased from W3 to W4 during operation, where W4>W3.

[0379] If the slow-release gas concentration is determined to be 0≤Y<Y, it indicates that the odor-purifying material in the odor-purifying component 121 has been completely consumed and needs to be replaced. At this time, the controller 600 outputs a prompt message reminding the user to replace the odor-purifying device 12. If the user still does not replace it after the reminder, the controller 600 will no longer control the operation of the odor-purifying device 12 after the end of the time interval T0. After confirming that the odor-purifying device 12 has been replaced, the controller 600 will control the operation of the odor-purifying device 12 based on the determined odor level.

[0380] Some embodiments of the present disclosure provide a method for controlling a refrigerator 1000, and the method may be performed by a controller 600. Referring to Figure 26 , the method includes steps S1 to S2.

In this way, compared with the ion odor purification technology and the ozone odor purification technology in the related art, the generation of ozone that harms the cabinet 10 and the human body is avoided, and the installation structure is simple and can be replaced at any time. In addition, according to the extent to which the first detection component 11 is affected by the odor, the sustained release rate of the odor purification substance in the odor purification component 121 is controlled in a timely manner, thereby improving the accuracy of odor purification.
