[0065] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0066] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0067] In the embodiments of this application, such as Figure 1-3 As shown, the basic structure of a refrigerator includes at least a cabinet 1, storage compartments, a compressor 2, an evaporator, and a cooling system. The storage compartments can be at least one of a freezer compartment 102, a refrigerator compartment 101, and a curing compartment. The evaporator is located in an evaporator cavity and is connected to the compressor 2 via a refrigerant circulation pipeline. The evaporator's temperature decreases under the action of the refrigerant in the compressor 2 and the circulation pipeline, serving as a cold source for temperature regulation in each storage compartment. The cooling system is used to directly or indirectly deliver the cooling capacity of the evaporator to each storage compartment. Optionally, the cooling system includes a connected evaporator cavity, a fan, a supply air duct, and a return air duct 3, wherein the storage compartments are located between the supply air duct and the return air duct 3. An evaporator is installed inside the evaporator cavity. After the airflow in the evaporator cavity exchanges heat with the evaporator, a cooling airflow is formed. The fan can drive the airflow in the evaporator cavity to flow into the air supply duct, and then drive the airflow to flow in the air supply duct. The cooling airflow in the air supply duct exchanges heat with each storage compartment, reducing the temperature in the storage compartment. After heat exchange, the airflow enters the return air duct 3 and finally enters the evaporator cavity, completing the airflow circulation.

[0068] The refrigerator provided in this application embodiment includes at least a freezer compartment 102 and a refrigerator compartment 101. The air-cooling system, in addition to the supply air duct and return air duct 3, also includes an outlet air duct 4. The evaporator chamber is connected to the freezer compartment 102 via the supply air duct, the refrigerator compartment 101 is connected to the defrosting area of ​​the evaporator via the return air duct 3, and the freezer compartment 102 is connected to the refrigerator compartment 101 via the outlet air duct 4. An evaporator is installed inside the evaporator cavity. After heat exchange with the evaporator, the airflow in the evaporator cavity forms a cooling airflow. The fan can drive the airflow in the evaporator cavity into the air supply duct, and then drive the airflow to flow in the air supply duct. The cooling airflow in the air supply duct enters the freezer compartment 102 for heat exchange, reducing the temperature in the freezer compartment 102 to the target temperature. The airflow in the freezer compartment 102 will continue to enter the refrigerator compartment 101 through the air outlet duct 4. After heat exchange in the refrigerator compartment 101, the airflow enters the return air duct 3 and finally returns to the evaporator cavity, completing the airflow circulation.

[0069] like Figure 3-13 As shown, the refrigerator in this embodiment of the application further includes a return air deodorization module 5, a temperature control module, and a sterilization and deodorization module 7. Wherein, as... Figure 3-8 As shown, the return air odor removal module 5 includes a first odor removal unit, an odor sensor, and a grille 501 disposed within the return air duct 3. The first odor removal unit is at least disposed on the windward surface of the grille 501. The grille 501 controls the projected area of ​​its windward surface perpendicular to the airflow direction by changing its angle. Figure 9-13 As shown, the temperature control module includes an airbag 6 disposed within the air outlet duct 4 and a temperature sensor disposed at the air outlet 401 of the air outlet duct 4. The airbag 6 controls the airflow through the air outlet duct 4 by changing its volume. Figure 9 As shown, the sterilization and deodorization module 7 is distributed on the cold storage compartment cover 105, and the sterilization and deodorization module 7 includes a sterilization unit and a colony detection sensor.

[0070] The return air deodorization module 5 is preferably located in the return air duct 3 within the foam layer between the refrigerator compartment 101 and the freezer compartment 102, and the return air deodorization module 5 is located near the entrance of the return air duct 3. When the grille 501 is opened at a certain angle, the windward surface of the grille 501 has a certain orthographic projection area in the vertical direction of the airflow. The larger the orthographic projection area of ​​the windward surface of the grille 501 in the vertical direction of the airflow, the better the purification effect of the first odor-removing unit on the grille 501 on the airflow passing through it. The first odor-removing unit includes, but is not limited to, adsorption material layers such as nano-mineral crystals, activated carbon, bamboo charcoal, activated alumina, and honeycomb ceramics used for adsorption and deodorization. When the grille 501 is opened at an angle perpendicular to the airflow direction, the windward surface of the grille 501 has the largest orthographic projection area in the vertical direction of the airflow, and the first odor-removing unit on the grille 501 has the greatest purification effect on the airflow passing through it. When the grille 501 is opened at an angle parallel to the airflow direction, the windward surface of the grille 501 has the smallest orthographic projection area in the vertical direction of the airflow, and the first odor-removing unit on the grille 501 has the least purification effect on the airflow passing through it.

[0071] When the odor parameter value obtained by the odor sensor exceeds the limit, the grille 501 opens at a certain angle according to the value calculated by the system. The return air of the refrigerator compartment 101 will pass through the first deodorizing unit on the grille 501 until the odor parameter value obtained by the odor sensor reaches the preset value. At this point, the grille 501 is fully opened, that is, the windward surface of the grille 501 is parallel to the airflow direction. If the odor parameter value is high, the grille is fully closed, that is, the windward surface of the grille 501 is perpendicular to the airflow direction, in order to improve the deodorizing effect.

[0072] For the temperature control module, when the temperature sensor obtains a temperature parameter value close to the set temperature, and the difference between the two is within a certain range, it indicates that the temperature in this area is too high and there is a cooling request. According to the system calculation results, the compressor 2 increases the cooling capacity by increasing its speed parameter, and the fan speed parameter increases the cooling capacity transfer speed. Furthermore, the airbag 6 located in the air outlet duct 4... Figure 12 As shown, by reducing the volume, the airflow through the outlet duct 4 is increased; when the temperature sensor obtains a temperature parameter value exceeding the set temperature, the difference between the two exceeds the limit, indicating that the temperature in this area is suitable and there is no cooling demand, and the compressor 2 speed parameter and fan speed parameter remain unchanged; when the temperature sensor obtains a temperature parameter value lower than the set temperature, and the difference between the two exceeds the limit, it indicates that the temperature in this area is too low, the refrigerator's cooling capacity is too high, the compressor 2 and fan stop rotating, and the airbag 6 located in the outlet duct 4... Figure 13 The air duct is fully open, preventing the cold air in the freezer compartment 102 from being transported to the refrigerator compartment 101 through the air outlet duct 4.

[0073] For the sterilization and deodorization module 7, the colony detection sensor periodically detects the number of colonies and the concentration of harmful bacteria and viruses in the refrigerator compartment 101 after the door is closed. When needed, the sterilization unit can directionally release corresponding sterilization substances or remove and optimize bacteria and viruses through other means. The sterilization unit can use ultraviolet light and other sterilization methods, and displays the colony value and risk level on the refrigerator's display panel 104, reminding the user to keep the refrigerator compartment 101 door 103 closed during the sterilization period.

[0074] In the above embodiment, the return air deodorization device is located in the return air duct between the refrigerator compartment 101 and the freezer compartment 102. It purifies the return air before it is directed to the evaporator defrosting area, thus improving the odor of the return air in the refrigerator compartment 101. The temperature control module improves the refrigerator's refrigeration cycle structure, optimizes the airflow ratio and air circulation path, maximizing the cooling effect and reducing energy loss within a limited space. The sterilization and deodorization module 7 improves the deodorization and sterilization effect in the refrigerator compartment 101, solving the problem of excessive harmful bacteria colony levels.

[0075] In some embodiments, such as Figure 8 As shown, the return air odor removal module 5 also includes a guide plate 502 and a guide plate motor 503 disposed at the inlet of the return air vent 301 of the return air duct 3. The guide plate motor 503 is used to adjust the curvature of the guide plate 502. Due to the setting of the grille 501, after the grille 501 rotates at a certain angle, the windward surface of the grille 501 increases the contact between the first odor removal unit and the airflow, while also obstructing the airflow, thus affecting the airflow circulation efficiency in the refrigerator. The guide plate 502 is provided in the return air duct 3, and the guide plate 502 can be adjusted to bend, forming a negative pressure suction state when the airflow passes through, accelerating the return air speed, alleviating the problem of low airflow circulation efficiency caused by the obstruction of the grille 501, and avoiding the reduction of airflow speed, while also facilitating the melting effect of ice on the evaporator by the return air at a certain speed.

[0076] In some embodiments, in the return air odor removal module 5, multiple grilles 501 are sequentially arranged along the airflow path within the return air duct 3, and each grille 501 is equipped with an odor sensor. Each grille 501 corresponds to an odor sensor located at its position, and the angle of the corresponding grille 501 is adjusted based on the odor parameter value detected by the odor sensor. By using multiple grilles 501 and odor sensors sequentially arranged along the airflow path, the return air can be thoroughly deodorized. Furthermore, as the upstream grilles 501 purify the return air, the odor parameter value of the return air will show a continuous decreasing trend, and the rotation angle of the downstream grilles 501 will become smaller and smaller overall. That is, along the direction of airflow, the obstruction of the airflow by the grilles 501 becomes smaller and smaller. This allows the purification function of the return air to be distributed to multiple grilles 501 along the airflow path, avoiding excessively large rotation angles of a single grille 501 that would cause excessive obstruction to the airflow.

[0077] In some embodiments, the temperature control module further includes a second deodorizing unit disposed on the surface of the airbag 6. The second deodorizing unit includes, but is not limited to, an adsorption material layer for adsorption and deodorization, such as nano-mineral crystals, activated carbon, bamboo charcoal, activated alumina, and honeycomb ceramics. After passing through the second deodorizing unit on the surface of the airbag 6, the cold air carrying the cooling capacity flows from the air outlet 401 of the air outlet duct 4 to the refrigerator compartment 101, adsorbing the odors carried by items such as fish, shrimp, and meat that may be present in the freezer compartment 102. When the actual temperature measured by the temperature sensor is close to the set temperature, i.e., the difference is within a limited range, the cooling capacity is appropriate, the compressor 2 speed and fan speed are maintained at the current state, and the airbag 6 in the air outlet duct 4 can open to a certain size according to the system's comprehensive calculation of temperature and deodorizing parameters. If the temperature parameter deviates significantly, the opening is smaller to prioritize temperature; if the odor parameter deviates significantly, the opening is larger, so that the airbag 6 has a larger surface area to achieve full contact between the airflow and the second deodorizing unit, prioritizing the deodorizing effect.

[0078] In some embodiments, such as Figure 11 As shown, the air outlet duct 4 includes several branch air outlet channels 402, each branch air outlet channel 402 forming an air outlet 401 connecting to the refrigerator compartment 101. Multiple airbags 6 are provided and distributed within each branch air outlet channel 402, and multiple temperature sensors are provided and distributed at the air outlet 401 of each branch air outlet channel 402. Through the cooperation of the branch air outlet channels 402, airbags 6, and temperature sensors, the temperature at the air outlet 401 of each branch air outlet channel 402 can be independently controlled, thereby achieving zoned temperature control within the refrigerator compartment 101, making temperature regulation more precise and targeted. The branch air outlet channels 402 and air outlets 401 can both be installed on the cover 105 of the refrigerator compartment 101.

[0079] In some embodiments, multiple sterilization and deodorization modules 7 are distributed on the refrigerator compartment face shield 105. Specifically, they can be set according to the storage area in the refrigerator compartment 101. For example, they can be arranged according to the shelves and fruit and vegetable boxes in the refrigerator compartment 101. When needed, the sterilization unit can directionally emit sterilization substances, ultraviolet light, or perform other sterilization methods.

[0080] Based on the same technical concept, this application also provides a method for operating a refrigerator, such as... Figure 14 As shown, the refrigerator's operating methods include air return and deodorization, temperature control, and sterilization and deodorization.

[0081] The air return deodorization method includes: adjusting the angle of the grille according to the odor parameter value detected by the odor sensor, so as to adjust the positive projection area of ​​the grille's windward surface perpendicular to the airflow direction.

[0082] The temperature control method includes: adjusting the compressor speed parameters and fan speed parameters according to the temperature value detected by the temperature sensor, and adjusting the volume of the air bag to adjust the amount of cold air entering the refrigerator compartment from the freezer compartment.

[0083] The sterilization and deodorization method includes: controlling the sterilization unit to sterilize all or part of the cold storage room based on the number of colonies detected by the colony detection sensor.

[0084] In the above implementation, the return air deodorization method utilizes a return air deodorization module located in the return air duct between the refrigerator and freezer compartments to purify the return air before it is directed to the evaporator defrosting area, thus improving the odor of the return air in the refrigerator compartment. The temperature control method improves the refrigerator's refrigeration cycle, optimizes the airflow ratio and air circulation path, maximizing the cooling effect and reducing energy loss within a limited space; the sterilization and deodorization method improves the deodorization and sterilization effect in the refrigerator compartment, solving the problem of excessive harmful bacteria colony levels.

[0085] In some embodiments, in the air return deodorization method: when the odor parameter value R detected by the odor sensor is greater than a first limit value Rx and less than a second limit value Ry, the angle of the grille is adjusted so that the windward surface of the grille is tilted relative to the airflow direction until the odor parameter value R is lower than the first limit value Rx. When the odor parameter value R detected by the odor sensor is greater than or equal to the second limit value Ry, the angle of the grille is adjusted so that the windward surface of the grille is perpendicular to the airflow direction until the odor parameter value R is lower than the second limit value Ry.

[0086] When the odor parameter value R is greater than the first limit value Rx and less than the second limit value Ry, although the odor parameter value R is relatively large, it is not necessary to adjust the windward side of the grille to be perpendicular to the airflow, thus minimizing the grille's obstruction effect on the airflow. When the odor parameter value R detected by the odor sensor is greater than or equal to the second limit value Ry, it indicates that the odor in the return air is too strong. To ensure a better odor removal effect, the odor removal function of the first odor removal unit needs to be fully activated. In this case, the windward side of the grille needs to be adjusted to be perpendicular to the airflow to achieve the maximum odor removal effect. Preferably, Ry ≥ 2Rx.

[0087] In some embodiments, in the temperature control method, when the difference between the temperature value T detected by the temperature sensor and the set temperature T0 of the cold storage compartment satisfies T-T0>Tx, the airbag is adjusted to a fully contracted state, and the rotational speed parameters of the compressor and the fan are increased, where Tx>0; when T0-T>Ty is satisfied, the airbag is adjusted to a fully expanded state, and the airbag adheres to the inner wall of the air outlet duct to block the air outlet duct, and the compressor and the fan stop rotating, where Ty>0; when T-T0≤Tx and T0-T≤Ty are satisfied, the airbag is adjusted to a state between fully contracted and fully expanded, with a gap between the airbag and the inner wall of the air outlet duct, and the rotational speeds of the compressor and the fan remain unchanged.

[0088] In some embodiments, in the sterilization and deodorization method, the sterilization unit is activated when the colony count S detected by the colony detection sensor is greater than a second limit value Sx.

[0089] In some embodiments, multiple grilles are arranged sequentially along the airflow path, and each grille is equipped with a corresponding odor sensor. The return air odor removal module sequentially applies the return air odor removal method to the area where each grille is located.

[0090] For example, specific methods for deodorizing return air can be as follows: Figure 15 As shown, the odor sensors and grilles in each region k are controlled independently.

[0091] (1) The odor parameter value detected by the odor sensor in area k is denoted as Rk, and the first limit value of the odor parameter value is Rx. The size of Rk and Rx is compared. If Rk > Rx, the system executes the return air deodorization program E; if Rk ≤ Rx, the grille in area k is fully opened with an opening angle of 0, and the windward side of the grille is set parallel to the airflow direction.

[0092] (2) When Rk > Rx, calculate RkE = Rk - Rk and determine the range of odor parameter values ​​to which RkE belongs.

[0093] If RkE belongs to the odor value range E1, then the opening angle mode of the grille in region k is θ1;

[0094] If RkE belongs to the odor value range E2, then the opening angle mode of the grille in region k is θ2;

[0095] ...

[0096] If RkE belongs to the odor value range Eq, then the opening angle mode of the grille in region k is θq.

[0097] The values ​​in the range E1-Eq show a gradually increasing trend. E1 represents the minimum range of the set odor parameter values, and Eq represents the maximum range of the set odor parameter values. In mode θ1, the opening angle of the grille is relatively small, and the windward side of the grille has a relatively small obstruction effect on the airflow. In modes θ1-θq, the opening angle of the grille shows a gradually increasing trend, and the windward side of the grille gradually increases its obstruction effect on the airflow. In mode θq, the opening angle of the grille is the largest, the windward side of the grille is perpendicular to the airflow channel direction, and the grille has the greatest obstruction effect on the airflow.

[0098] (3) After the return air deodorization module sequentially uses the above-mentioned return air deodorization method to complete the angle adjustment of each area where the grille is located, the airflow in the return air duct enters the defrosting area of ​​the evaporator in the evaporator cavity, and the refrigerator executes the return air defrosting control program.

[0099] In some embodiments, the air outlet duct includes several branch air outlet channels, each branch air outlet channel forming an air outlet connecting the cold storage compartment. Multiple airbags are provided and distributed in each branch air outlet channel. Multiple temperature sensors are provided and distributed at the air outlet of each branch air outlet channel. The temperature control module sequentially applies the temperature control method to the area where each air outlet is located.

[0100] For example, a specific temperature control method may be as follows: Figure 16 As shown, the airbags and temperature sensors at the air outlets of each branch air outlet channel i are controlled independently.

[0101] (1) The temperature value detected by the temperature sensor in area i is Ti, the set temperature of the cold storage room is T0, the first limit value of the temperature value is Tx, the second limit value is Ty, and both Tx and Ty are positive numbers.

[0102] ① When the measured temperature Ti > T0 and Ti - T0 > Tx in region i, the system executes cooling program A;

[0103] ② When Ti-T0≤Tx or T0-Ti≤Ty, the system executes cooling program B;

[0104] ③ When Ti < T0 and T0 - Ti > Ty, the system executes the cooling program C.

[0105] (2) In the refrigeration program A, calculate TiA = Ti - T0 and determine the temperature range to which TiA belongs.

[0106] If TiA belongs to temperature range A1, then the compressor speed increases by 1 level, the fan speed increases by 1 level, and the volume of the airbag in region i inside the hood of the cold storage compartment is φA, where φA represents the airbag being fully contracted.

[0107] If TiA belongs to temperature range A2, then the compressor speed increases by 2 levels, the fan speed increases by 2 levels, and the volume of the airbag in region i inside the hood of the cold storage compartment is φA, where φA represents the airbag being fully contracted.

[0108] ...

[0109] If TiA belongs to the temperature range Ag, then the compressor speed increases by g, the fan speed increases by g, and the volume of the airbag in region i inside the refrigeration compartment is φA, where φA represents the airbag being fully contracted.

[0110] The values ​​in the range A1-Aq show a gradually increasing trend. A1 represents the minimum temperature range set in cooling program A, and Ag represents the maximum temperature range set in cooling program A.

[0111] Once the temperature in region i meets the temperature range TA set in cooling program A, the temperature regulation of cooling program A is completed.

[0112] (3) In the refrigeration program B, the compressor speed and fan speed are kept at the existing parameters. Calculate TiB = Ti - T0 and determine the temperature range to which TiB belongs.

[0113] If TiB belongs to temperature range B1, then the volume of the airbag in region i inside the hood of the cold storage compartment is ΦB1.

[0114] If TiB belongs to temperature range B2, then the airbag volume of region i inside the hood of the cold storage compartment is ΦB2.

[0115] ...

[0116] If TiB belongs to the temperature range Bh, then the airbag volume of region i inside the hood of the cold storage compartment is ΦBh.

[0117] The values ​​in the range B1-Bh show a gradually increasing trend. B1 represents the minimum temperature range set in cooling mode B, and Bh represents the maximum temperature range set in cooling mode B.

[0118] Once the temperature in region i meets the temperature range TB set in cooling program B, the temperature regulation of cooling program B is completed.

[0119] (4) In the refrigeration program C, the compressor speed and the fan stop rotating. The volume of the air bladder in area i inside the refrigeration compartment is Φmax. φmax indicates that the air bladder is fully open and completely closes the branch air outlet channel of area i.

[0120] In some embodiments, multiple sterilization and deodorization modules are distributed on the refrigeration compartment cover, and the sterilization and deodorization modules sequentially apply the sterilization and deodorization method to each area.

[0121] For example, specific methods for sterilization and deodorization can be as follows: Figure 17 As shown, the sterilization and deodorization modules in each area j are controlled independently.

[0122] (1) The colony count detected by the colony detection sensor in area j is Sj, and the limit value of the colony count is Sx. Compare the size of Sj and Sx. If Sj > Sx, the system executes the sterilization and deodorization program D for area j, and the display screen prompts that the sterilization and deodorization function is turned on. It is recommended to keep the refrigerator compartment closed within the sterilization set time tc. If Sj ≤ Sx, the sterilization and deodorization program D is not executed in area j, and the sterilization and deodorization method in area j ends.

[0123] (2) When Sj > Sx, calculate SjD = Sj - SX and determine the range of colony values ​​to which SjD belongs.

[0124] If SjD belongs to the colony count range D1, then the sterilization unit in region j will activate sterilization setting e1.

[0125] If SjD belongs to the colony count range D2, then the sterilization unit in region j will activate sterilization setting e2.

[0126] ...

[0127] If SjD belongs to the colony count range Dp, then the sterilization unit in region j will activate the sterilization setting ep.

[0128] The values ​​in the range D1-Dp show a gradually increasing trend. D1 is the minimum range of the set colony count, and Dp is the maximum range of the set colony count. The sterilization intensity of the sterilization levels e1-ep gradually increases.

[0129] (3) When the colony count in region j meets the range SD set in the sterilization and deodorization procedure D, the sterilization and deodorization method in region j ends.

[0130] In some embodiments, the refrigerator compartment is divided into several sub-areas, each of which is equipped with an air outlet for a branch air outlet duct, an air inlet for a return air duct, and a sterilization and deodorization module. This allows each sub-area to be equipped with a return air deodorization module, a temperature control module, and a sterilization and deodorization module, enabling independent control of each sub-area within the refrigerator compartment. This makes the return air deodorization effect, sterilization and deodorization effect, and temperature control effect more precise and targeted, while saving energy.

[0131] To further improve the control indicators in each sub-zone of the refrigerator compartment, and to ensure that the refrigerator prioritizes the execution of the most needed programs, some embodiments of this application also include a priority determination method. For example... Figure 18 As shown, the priority determination method for each working method within any sub-region z of the cold storage room includes:

[0132] (1) When the measured temperature value Tz of sub-region z is greater than the set temperature T0, calculate the ratio u = Tz / T0 of the measured temperature to the set temperature in the sub-region. When calculating, if there are multiple air outlets in sub-region z, Tz is the average value of the temperature values ​​obtained by the temperature sensors at all air outlets in sub-region z.

[0133] (2) When the colony count Sz of subregion z is greater than the limit value Sx, calculate the ratio of the colony count of subregion z to the set optimal colony count: v = Sz / S0. Wherein, when multiple sterilization and deodorization modules are set in subregion z, Tz is the average value of the colony counts obtained by all colony detection sensors in subregion z.

[0134] (3) When the odor parameter value Rz of sub-region z > the limit value Rx, calculate the ratio of the odor parameter value of sub-region z to the set optimal odor parameter value: w = Rz / R0. Wherein, during the calculation, Rz is selected as the odor parameter value detected by the odor sensor closest to the return air vent in the return air duct. When there are multiple return air ducts in sub-region z, Tz is the average value of the odor parameter values ​​detected by the odor sensor closest to the return air vent in all return air ducts in sub-region z.

[0135] (4) When u>v and u>w, the temperature control method has the highest priority and is executed first.

[0136] ①If u>v>w, then the priority order within sub-region z is temperature control method, sterilization and deodorization method, and return air deodorization method, in that order.

[0137] ②If u>w>v, then the priority order within sub-region z is temperature control method, return air deodorization method, and sterilization deodorization method, in that order.

[0138] (5) When v>u and v>w, the sterilization and deodorization method has the highest priority and should be executed first.

[0139] ①If v>u>w, then the priority order within sub-region z is sterilization and deodorization method, temperature control method, and return air deodorization method, in that order.

[0140] ②If v>w>u, then the priority order within sub-region z is sterilization and deodorization method, return air deodorization method, and temperature control method, in that order.

[0141] (6) When w>u and w>v, the return air deodorization method has the highest priority and is executed first.

[0142] ①If w>u>v, then the priority order within sub-region z is, in order, return air deodorization method, temperature control method, and sterilization deodorization method;

[0143] ②If w>v>u, then the priority order within sub-region z is as follows: return air deodorization method, sterilization deodorization method, and temperature control method.

[0144] like Figure 19 As shown, an exemplary flowchart illustrates the refrigerator operation method within subregion z when u>v>w is satisfied.
