[0002] In the prior art, refrigerators that do not carry over odors are usually dual-system refrigerators, which require the design of independent refrigeration evaporators and freezing evaporators. Some solutions also use single-system refrigerators, which share a set of compressors and refrigeration pipelines. The refrigeration evaporator and the freezing evaporator are connected in series. When one of the refrigerator or freezer compartments has a cooling demand, the compressor needs to output pump work.

[0070] The present application provides an anti-odor refrigerator and a control method, a control device and a storage medium thereof to solve the problem of high energy consumption of existing refrigerators. Figure 1-15 Provide explanation.

[0071] Existing refrigerators that do not carry odors are generally dual-system refrigerators, which require the design of separate refrigeration evaporators, refrigeration fans, solenoid valves and other components, and the refrigeration switching between refrigeration and freezing is achieved through the solenoid valve.

[0072] In the related art, a single-system refrigerator that does not carry over odors shares a set of compressors and refrigeration pipelines, and the freezing evaporator and the refrigerating evaporator are connected in series. When one of the refrigerator or freezer compartments has a cooling demand, the compressor needs to output pump work, but the evaporator corresponding to the non-refrigerated compartment also needs to consume additional pump work while cooling the other compartment, resulting in additional consumption of cooling capacity, causing the refrigerator to consume more electricity and poor energy-saving effect.

[0073] The refrigerator of the embodiment of the present application is a single-system refrigerator that prevents odor contamination. For example, the refrigerator is provided with a freezer and a refrigerator, and the refrigerator's refrigeration system includes a compressor, a condenser, a refrigeration evaporator and a freezing evaporator connected in sequence. The refrigeration evaporator is connected in series with the freezing evaporator, and the refrigeration evaporator is located at the front end of the freezing evaporator, that is, the refrigerant first flows through the refrigeration evaporator and then flows through the freezing evaporator. At the same time, a freezing fan, a refrigeration fan, a freezing damper and a refrigeration damper are also provided. The freezing fan is used to blow air toward the freezing chamber, the refrigeration fan is used to blow air toward the freezing chamber, the refrigeration damper is arranged between the refrigeration fan and the refrigerator, and is used to adjust the opening of the refrigeration air duct to adjust the refrigeration speed of the refrigerator, and the freezing damper is arranged between the freezing fan and the freezing chamber, and is used to adjust the opening of the freezing air duct to adjust the refrigeration speed of the freezing chamber.

[0074] When the refrigerator starts working, the compressor starts and compresses the refrigerant into high-temperature and high-pressure gas. The gas then enters the condenser, where it is cooled and condensed into a high-pressure liquid. The refrigerant then flows through the refrigeration evaporator, where it evaporates and absorbs heat, lowering the temperature of the refrigerator compartment. Since the refrigeration evaporator is located in front of the freezing evaporator, the refrigerator compartment starts to refrigerate before the freezer compartment. Then, the refrigerant continues to flow and enters the freezing evaporator. In the freezing evaporator, the refrigerant evaporates again and absorbs more heat, further lowering the temperature of the freezer compartment. In this way, the freezer compartment can reach a lower temperature and is used to store food that needs to be kept fresh or frozen for a long time.

[0075] According to one embodiment of the present application, referring to Figure 1 As shown, the control method of the anti-odor refrigerator includes:

[0076] S101: Obtaining the working cycle information of the compressor and the refrigeration temperature of the refrigeration chamber.

[0077] Specifically, a temperature sensor may be provided in the refrigerating chamber to measure the temperature of the refrigerating chamber; there may be multiple temperature sensors, which may be provided at multiple locations and corners of the refrigerating chamber to improve the accuracy of detecting the temperature of the refrigerating chamber.

[0078] Exemplarily, the working cycle information of the compressor may be determined by monitoring the startup time and shutdown time of the compressor. For example, the time from one startup time of the compressor to the next startup time of the compressor may be regarded as a working cycle of the compressor.

[0079] S102: Based on the duty cycle information, determine a working mode corresponding to the duty cycle information.

[0080] In an optional embodiment, step S102 includes determining that the target operating mode corresponding to the working cycle information is a first target operating mode when the working cycle is the first working cycle after power-on, defrosting or door opening and closing; and determining that the target operating mode corresponding to the working cycle information is a second target operating mode when the working cycle is the working cycle after the first working cycle; wherein the first target operating mode is configured such that the refrigeration damper is opened at a preset opening, and the refrigeration fan and the compressor operate at their respective corresponding preset speeds; and the second target operating mode is configured to adjust at least one of the opening of the refrigeration damper, the speed of the refrigeration fan and the speed of the compressor.

[0081] Due to the working cycle after the first power-on, defrosting, and door opening and closing, the refrigerator is usually in an unstable operating state. At this time, iterating the operating speed of each load cannot obtain the ideal temperature balance state. Therefore, in the first working cycle, the compressor, refrigeration fan and refrigerator fan are controlled according to the preset first target working mode, that is, the refrigeration damper is controlled to open at a preset opening, and the refrigeration fan and compressor are operated at a preset speed. Starting from the second working cycle of the compressor, the opening of the refrigeration damper, the speed of the refrigeration fan or the compressor speed are adjusted based on the refrigeration temperature, so that the refrigeration evaporator and the freezing evaporator can participate in refrigeration at the same time as much as possible, solving the problem of insufficient utilization of refrigerator cooling capacity and high power consumption.

[0082] In an optional embodiment, after obtaining the refrigeration temperature of the refrigerating chamber, the control method also includes: obtaining the freezing temperature of the freezing chamber; when the freezing temperature is greater than or equal to the preset freezing start-up temperature, turning on the compressor and the freezing damper; when the refrigeration temperature is greater than or equal to the preset refrigeration start-up temperature, opening the refrigeration damper; when the refrigeration temperature is greater than or equal to the preset refrigeration stop temperature, closing the refrigeration damper.

[0083] In this embodiment, when it is detected that the freezing temperature is greater than or equal to the preset freezing start-up temperature, it means that the temperature in the freezing chamber is higher than the set temperature, and the compressor and the freezing damper are turned on to refrigerate the freezing damper. When it is detected that the refrigeration temperature is greater than or equal to the preset refrigeration start-up temperature, it means that the refrigeration chamber needs to be refrigerated, and the refrigeration damper is opened to improve the refrigeration efficiency of the refrigeration chamber; when it is detected that the refrigeration temperature is less than or equal to the preset refrigeration shutdown temperature, it means that the refrigeration chamber has been refrigerated, and the refrigeration damper is closed. When the freezing temperature drops to the preset refrigeration shutdown temperature, it means that the freezing chamber has reached or is lower than the required refrigeration temperature. When it is detected that the refrigeration chamber does not need to be refrigerated, in order to save energy and avoid over-refrigeration, the compressor and the refrigeration fan can be turned off, and the temperature in the freezing chamber will gradually rise, but due to the thermal insulation performance of the freezing chamber, the freezing temperature will not immediately rise to above the preset freezing start-up temperature.

[0084] It can be understood that the preset freezing start-up temperature and the preset freezing stop temperature can be reasonably set according to the design of the refrigerator, the refrigeration energy and the user's usage habits. The preset freezing start-up temperature is greater than the preset freezing stop temperature, and a certain difference is maintained between the two to prevent the compressor from frequently starting and stopping and causing unnecessary wear and energy consumption on the refrigerator.

[0085] In this embodiment, the opening and closing of the compressor is controlled based on the freezing temperature rather than the refrigerating temperature because the freezing evaporator is usually larger than the refrigerating evaporator. If the opening of the compressor is controlled based on the refrigerating temperature, the freezing evaporator consumes more cooling energy when the refrigerating evaporator is turned on alone.

[0086] In an optional embodiment, the temperature difference between the on-off points of the refrigerating chamber is greater than the temperature difference between the on-off points of the freezing chamber.

[0087] In this embodiment, the temperature difference between the start and stop points of the refrigerating chamber is the difference between the preset refrigerating start temperature and the preset refrigerating stop temperature, and the temperature difference between the start and stop points of the freezing chamber is the difference between the preset refrigerating start temperature and the preset freezing stop temperature. Exemplarily, the temperature difference between the start and stop points of the refrigerating chamber is 3-5°C, such as 3°C, 3.5°C, 4°C, 4.5°C or 5°C, and the temperature difference between the start and stop points of the freezing chamber is 1-2°C, such as 1°C, 1.5°C or 2°C.

[0088] Normally, because the temperature of the freezer is lower than that of the refrigerator, when the temperature difference between the start and stop points is the same, the freezer has a longer start time and a shorter stop time. Therefore, by setting the temperature difference between the start and stop points of the refrigerator to be greater than that of the freezer, for example, the temperature difference between the start and stop points of the refrigerator is 3.5°C, and the temperature difference between the start and stop points of the freezer is 1.5°C. Under this parameter, the start and stop cycle durations of the two compartments are relatively close, and have a relatively suitable temperature fluctuation range and compressor shutdown time, which fully utilizes the cooling capacity of the evaporator and saves energy.

[0089] In an optional embodiment, when the working mode is the second target working mode, the operating parameters of at least one of the refrigeration damper, the freezer fan and the compressor are adjusted based on the working mode and the refrigeration temperature, including: when the refrigeration temperature is greater than or equal to the preset refrigeration shutdown temperature, opening the refrigeration damper; when the refrigeration temperature is greater than or equal to the preset refrigeration startup temperature, reducing the opening of the refrigeration damper; and / or, increasing the speed of the freezer fan; and / or, increasing the speed of the compressor.

[0090] In this embodiment, at the moment when the compressor is turned on, it is judged whether the refrigeration temperature is greater than or equal to the preset refrigeration shutdown temperature. If so, the refrigeration fan is controlled to start working, so that the refrigerator and the freezer start refrigeration at the same time. However, the temperature difference between the start and stop points of the refrigerator is set to 3.5°C, which is already a relatively large fluctuation range. Therefore, it is further judged whether the refrigeration temperature is greater than or equal to the preset refrigeration startup temperature. If so, it means that the start and stop cycle of the refrigerator is still smaller than that of the freezer, and the actual temperature fluctuation range of the refrigerator exceeds 3.5°C. Therefore, at this time, the refrigeration efficiency of the refrigerator can be reduced by reducing the opening of the refrigeration damper to extend the first refrigeration time of the refrigerator, or the refrigeration efficiency of the freezer can be increased by increasing the speed of the refrigeration fan and the speed of the compressor, and the second refrigeration time of the freezer is reduced, so that the first refrigeration time and the second refrigeration time are as equal as possible, and finally the refrigeration temperature of the refrigerator is maintained in a stable operating state within the fluctuation range of the start and stop temperature difference of 3.5°C.

[0091] S103: Based on the working mode and the refrigeration temperature, adjust the operating parameters of at least one of the refrigeration damper, the freezing fan and the compressor to increase the first refrigeration time of the refrigeration evaporator or reduce the second refrigeration time of the freezing evaporator.

[0092] Optionally, within one working cycle of the compressor, the working time of the refrigeration evaporator is a first refrigeration time, and the working time of the freezing evaporator is a second refrigeration time. By increasing the first refrigeration time of the refrigeration evaporator or reducing the second refrigeration time of the freezing evaporator, the difference between the first refrigeration time and the second refrigeration time is within a preset difference range, so that the refrigeration evaporator and the freezing evaporator participate in refrigeration as much as possible at the same time, avoiding the problem of insufficient utilization of cooling capacity and high power consumption caused by cooling a single compartment while the other compartment is not cooled.

[0093] In an optional embodiment, the difference between the first refrigeration time and the second refrigeration time is within a preset difference range. The preset difference range of this embodiment is very small compared to the working cycle of the compressor. The preset difference range can be 10-60s. For example, the preset difference range can be 10s, 20s, 30s, 40s or 60s, etc. By making the preset difference range as small as possible, the first refrigeration time and the second refrigeration time are as equal as possible.

[0094] In an optional embodiment, the refrigeration fan and the freezing fan can be driven by the same motor, that is, one end of the output shaft of the motor is connected to the refrigeration fan, and the other end is connected to the freezing fan. The refrigeration fan and the freezing fan can be driven to work at the same time, saving a set of driving motors and saving energy.

[0095] In an alternative embodiment, reference Figure 2As shown, when the refrigeration temperature is greater than or equal to the preset refrigeration start-up temperature, the opening of the refrigeration damper is reduced; and / or, the speed of the refrigeration fan is increased; and / or, the speed of the compressor is increased, including:

[0096] S201: When the refrigeration temperature is greater than or equal to the preset refrigeration start-up temperature, obtaining the current opening of the refrigeration damper;

[0097] S202: When the current opening is greater than the preset opening, reducing the opening of the refrigeration damper;

[0098] S203: When the current opening degree is equal to the preset opening degree, obtaining first speed information of the refrigeration fan;

[0099] S204: when the first speed information is less than the first preset speed, increasing the speed of the refrigeration fan;

[0100] S205: When the first speed information is equal to the first preset speed information, increase the speed of the compressor.

[0101] It can be understood that in this embodiment, the opening of the refrigeration damper, the speed of the freezing fan and the speed of the compressor are adjusted in order of priority from high to low. When it is detected that the refrigeration temperature is greater than or equal to the preset refrigeration start-up temperature, the opening of the refrigeration damper is preferentially reduced to extend the synchronous refrigeration time of the refrigeration room. The opening of the refrigeration damper will have a minimum value. When the opening of the refrigeration damper is lower than the minimum value, the refrigeration temperature will not be able to be lowered. When the opening of the refrigeration damper is iterated to the minimum and still cannot meet the requirement, the speed of the freezing fan and the speed of the compressor are increased to reduce the duration of the freezing and refrigeration cycle, and finally a stable operating state with a refrigeration temperature ≤3.5℃ start-stop temperature difference can be obtained. The adjustment of the refrigeration damper and the rotation speed of the freezing fan and the compressor are all for optimizing the refrigeration time of refrigeration and freezing, so as to make the refrigeration evaporator and the freezing evaporator participate in refrigeration at the same time as much as possible. In this embodiment, the opening of the refrigeration damper is preferably reduced because it has the greatest advantage in reducing energy consumption. The next option is to increase the rotation speed of the freezing fan and the compressor to minimize the refrigeration energy consumption of the refrigerator.

[0102] In an optional embodiment, the control method further includes: when the refrigeration evaporator is turned off and the freezing temperature is less than or equal to the preset freezing shutdown temperature, turning off the compressor, the freezing fan and the refrigeration fan; and / or, when it is detected that the compressor is turned off, turning off the freezing fan and the refrigeration fan.

[0103] In this embodiment, during the non-refrigeration period of the refrigerator compartment, when the freezing temperature drops to the preset freezing shutdown temperature, it means that the freezer compartment has reached or is lower than the required refrigeration temperature. At this time, in order to save energy and avoid over-refrigeration, the compressor, the freezing fan and the refrigeration fan can be turned off, and the temperature in the freezer compartment will gradually rise. However, due to the thermal insulation performance of the freezer compartment, the freezing temperature will not immediately rise above the preset freezing start-up temperature.

[0104] For example, when it is detected that the compressor is turned off, the freezing fan and the refrigerating fan are turned off because the refrigeration system is no longer cooling at this time. Turning on the refrigerating fan will only consume extra energy, avoiding continuing to run the refrigerating fan when cooling is not needed, thereby reducing energy consumption.

[0105] For example, reference Figure 3 As shown, the process of the control method of the anti-odor refrigerator includes:

[0106] The freezing temperature is ≥ the preset freezing start temperature, the compressor is on, and the freezing fan is on;

[0107] Refrigeration temperature ≥ preset refrigeration start-up temperature, refrigeration damper open;

[0108] Refrigeration temperature ≤ preset refrigeration shutdown temperature, refrigeration damper closed;

[0109] During the non-refrigeration period, if the freezing temperature is less than or equal to the preset freezing shutdown temperature, the compressor will be shut down and the freezing fan will be turned off;

[0110] After the first power-on, defrosting, or door opening and closing, the system will resume operation at the preset refrigeration damper opening, refrigeration fan speed, and compressor speed.

[0111] And the second compressor cycle starts to judge:

[0112] When the compressor is turned on, if the refrigeration temperature is ≥ the preset refrigeration shutdown temperature, the refrigeration damper opens;

[0113] When the compressor is turned on, if the refrigeration temperature is ≥ the preset refrigeration start-up temperature, the opening angle of the refrigeration damper is reduced by 5°;

[0114] When the compressor is turned on, if the refrigeration temperature is ≥ the preset refrigeration start-up temperature, and the opening angle of the refrigeration damper is at the minimum, the refrigeration fan speed will be increased by one gear;

[0115] When the compressor is turned on, if the refrigeration temperature is ≥ the preset refrigeration start-up temperature, and the opening angle of the refrigeration damper is at the minimum, the refrigeration fan speed is at the highest level, and the compressor speed is increased by 150rpm.

[0116] In an optional embodiment, the refrigeration evaporator and the freezing evaporator are both arranged in the freezing air duct assembly, and a fan shielding structure is arranged in the freezing air duct assembly, and the refrigeration air door and the freezing air door are integrated on the fan shielding structure, and the fan shielding structure can move between a first position and a second position to control the opening of the refrigeration air door and the freezing air door (see the anti-odor refrigerator section below for details). Exemplarily, when the fan shielding structure moves to the first position, the freezing air door is opened and the refrigeration air door is closed, and when the fan shielding structure moves to the second position, the refrigeration air door and the freezing air door are both opened.

[0117] For example, reference Figure 4 As shown, the process of the control method of the anti-odor refrigerator includes:

[0118] When the freezing temperature is ≥ the preset freezing start-up temperature, the fan shielding structure moves to the first position, the freezing damper opens, and the refrigeration damper closes;

[0119] Refrigeration temperature ≥ preset refrigeration start-up temperature, the fan shielding structure moves to the second position, and the refrigeration damper and the freezing damper are both opened;

[0120] When the refrigeration temperature is less than or equal to the preset refrigeration shutdown temperature, the fan shielding structure moves to the first position;

[0121] During the non-refrigeration period, when the freezing temperature is ≤ the preset freezing shutdown temperature, the compressor stops, and the freezing fan and the refrigeration fan are turned off;

[0122] After the first power-on, defrosting, or door opening and closing, the system will resume operation according to the preset damper opening, refrigeration fan speed, and compressor speed.

[0123] And the second compressor cycle starts to judge:

[0124] When the compressor is turned on, if the refrigeration temperature is ≥ the preset refrigeration shutdown temperature, the fan shielding structure moves to the second position;

[0125] When the compressor is turned on, if the refrigeration temperature is ≥ the preset refrigeration start-up temperature, the fan shielding structure moves to the second position, and the number of action steps decreases (that is, the corresponding refrigeration damper opening decreases);

[0126] When the compressor is turned on, if the refrigeration temperature is ≥ the preset refrigeration start-up temperature, and the refrigeration damper opening corresponding to the fan shielding structure is at the minimum, the refrigeration fan speed is increased by one gear;

[0127] When the compressor is turned on, if the refrigeration temperature is ≥ the preset refrigeration start-up temperature, and the refrigeration damper opening corresponding to the fan shielding structure is at the minimum, the refrigeration fan speed is at the highest level, and the compressor speed is increased by 150rpm.

[0128] The control method for the anti-odor cross-contamination refrigerator provided in the embodiment of the present application is applied to the anti-odor cross-contamination refrigerator in which a freezing evaporator and a refrigerating evaporator are connected in series, the refrigerating evaporator and the freezing evaporator are respectively arranged in the corresponding refrigerating air duct and freezing air duct and are spaced apart to avoid odor cross-contamination, and based on the working cycle information of the compressor, the corresponding working mode is determined, and based on the working mode and the refrigerating temperature, the working parameters of at least one of the refrigerating damper, the refrigerating fan and the compressor are adjusted to reduce the refrigerating speed of the freezing evaporator or increase the refrigerating speed of the freezing evaporator, so that the refrigerating time of the refrigerating evaporator and the refrigerating time of the freezing evaporator are as equal as possible, thereby reducing the consumption of cold energy when the refrigerating evaporator or the freezing evaporator is refrigerated alone, saving the energy consumption of the refrigerator, and improving the user experience.

[0129] The embodiment of the second aspect of the present application refers to Figure 5 As shown, a control device for an anti-smell refrigerator is provided, the refrigerator comprises a freezing chamber, a refrigerating chamber, a freezing fan, a refrigerating fan, a refrigerating damper, a freezing damper, and a compressor, a freezing evaporator and a refrigerating evaporator connected in series, the refrigerating evaporator is located at the front end of the refrigerating evaporator, the refrigerating fan is used to blow cold air to the refrigerating chamber, the refrigerating fan is used to blow cold air to the freezing chamber, the refrigerating damper is arranged between the refrigerating fan and the refrigerating chamber, and the freezing damper is arranged between the refrigerating fan and the freezing chamber, and the control device comprises:

[0130] The acquisition module 501 is used to acquire the working cycle information of the compressor and the refrigeration temperature of the refrigeration chamber;

[0131] A determination module 502, configured to determine a working mode corresponding to the working cycle information based on the working cycle information;

[0132] The adjustment module 503 is used to adjust the operating parameters of at least one of the refrigeration damper, the freezing fan and the compressor based on the working mode and the refrigeration temperature to increase the first refrigeration time of the refrigeration evaporator or reduce the second refrigeration time of the freezing evaporator.

[0133] All of the above technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described in detail here.

[0134] In the control device of the anti-odor refrigerator provided in the embodiment of the present application, during the refrigeration process of the refrigerator, the freezing evaporator and the refrigerating evaporator can be cooled at the same time as much as possible, avoiding the need for the other evaporator to consume additional pump work when the refrigerating chamber or the freezing chamber is cooled separately, thereby reducing the consumption of cold energy and saving the power consumption of the refrigerator.

[0135] The embodiment of the third aspect of the present application, combined with Figure 6-Figure 14As shown, a refrigerator for preventing odor contamination is provided, comprising a freezing chamber 20, a refrigerating chamber 10, a compressor 1, a freezing evaporator 6, a refrigerating evaporator 5, a refrigerating air duct 101, a freezing air duct 201, a refrigerating fan 2011, a refrigerating fan 2012 and a controller, wherein the freezing evaporator 6 and the refrigerating evaporator 5 are arranged in the freezing chamber 20, the freezing evaporator 6 and the refrigerating evaporator 5 are connected in series, and the refrigerating evaporator 5 is located at the front end of the freezing evaporator 6; the refrigerating air duct 101 and the refrigerating air duct 201 are respectively provided with Refrigeration damper 1011 and freezing damper 2015, the refrigeration fan 2011 is installed in the refrigeration air duct 101, and is used to blow cold air toward the refrigeration chamber 10, the freezing fan 2012 is installed in the freezing air duct 201, and is used to blow cold air toward the freezing chamber 20, the controller is electrically connected to the compressor 1, the freezing evaporator 6, the refrigeration evaporator 5, the freezing fan 2012, the refrigeration damper 1011 and the freezing damper 2015 respectively, and the controller is used to execute the control method of the anti-odor refrigerator as in the above embodiment.

[0136] For example, reference Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the refrigeration system of the refrigerator includes a compressor 1, a condenser 2, a drying filter 3, a return air pipe assembly 4, a refrigeration evaporator 5 and a freezing evaporator 6 which are connected in sequence. The refrigeration evaporator 5 and the freezing evaporator 6 are connected in series, and the refrigeration evaporator 5 is located at the front end of the freezing evaporator 6, that is, the refrigerant first flows through the refrigeration evaporator 5 and then flows through the freezing evaporator 6. The air flowing through the refrigeration evaporator 5 returns to the refrigeration evaporator 5 after passing through the refrigeration return air duct 30, forming a circulating flow of air to cool the refrigeration chamber 10.

[0137] In an optional embodiment, the refrigerated evaporator 5 and the frozen evaporator 6 are an integrated component of a series structure, that is, the evaporator includes a first section and a second section, the first section is the refrigerated evaporator 5, and the second section is the frozen evaporator 6, the refrigerated fan 2011 and the frozen fan 2012 are both designed in the freezing air duct 201 component, and the refrigerated fan 2011 and the frozen fan 2012 can be coaxially arranged and share a motor and are driven by the same motor, and the evaporator is configured so that the front section (refrigerated evaporator 5) exchanges heat with the refrigerating chamber 10, and the rear section (frozen evaporator 6) exchanges heat with the freezing chamber 20.

[0138] Furthermore, the refrigeration damper 1011 and the freezing damper 2015 are an integrated structure and are integrally formed in the fan shielding structure 2014. The fan shielding structure 2014 is arranged in the freezing air duct 201. The fan shielding structure 2014 can move between a first position and a second position to open or close the freezing. When the freezing air duct 201 is moved to the first position, the freezing air duct 201 is opened and the refrigeration air duct 101 is closed. When the fan shielding structure 2014 moves to the second position, both the refrigeration air duct 101 and the freezing air duct 201 are opened. By designing the fan shielding structure 2014, there is no need to design separate refrigeration dampers 1011 and freezing dampers 2015. The opening of the refrigeration air duct 101 and the freezing air duct 201 can be flexibly coordinated to control the refrigeration efficiency of the refrigeration chamber 10 and the freezing chamber 20, and the integration of the refrigerator refrigeration system is also improved.

[0139] In an optional embodiment, the refrigerator is a cross-door refrigerator, and the lower freezer compartment 20 is divided into two compartments by a middle partition 202. The evaporator is placed in its entirety inside the box of the freezer compartment 20 and is located on the back of the freezing air duct 201 assembly. After the freezing air duct 201 assembly is assembled in place, the sealing rib 2013 can seal the refrigeration evaporator 5 in a chamber, which is only connected to the refrigeration return air duct 30 of the refrigeration compartment 10, and not to the freezing compartment 20. That is, the evaporator is divided into two parts in series by the sealing rib 2013, which are respectively refrigerated by the refrigeration air duct 101 and the freezing air duct 201, so as to ensure the larger refrigeration demand of the freezing air duct 201, and at the same time separate the refrigeration air duct 101 and the freezing air duct 201 to meet the anti-odor requirements of the refrigerator.

[0140] Compared with the traditional dual-system refrigerator, the refrigerator of this embodiment does not need to be equipped with a solenoid valve, simplifies the structure of the refrigeration system, and can reduce the maintenance cost caused by the failure of the solenoid valve. By designing the refrigeration evaporator 5 and the freezing evaporator 6 as an integrated component and integrating them in the back box of the freezer 20, not only the number of components is reduced, but also the integration and compactness of the system are improved, and the flow distance of the refrigerant in a cycle is reduced, so that the refrigerant can exchange heat more smoothly when flowing through the two evaporators, thereby improving the refrigeration efficiency. Compared with the general single-system refrigerator, the refrigeration return air duct 30, the return air pipe assembly 4 and other components can be used in common with the general single-system refrigerator, and the component commonality rate is higher, which can reduce the design cost and the cost of the whole machine.
