Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a refrigerator and a method for controlling the fresh air intake of a refrigerator. Background Technology

[0002] Currently, with the improvement of living standards, refrigerators have become an indispensable part of people's daily lives, as they can store and refrigerate items and extend their shelf life.

[0003] A refrigerator consists of a cabinet and a liner inside the cabinet, which forms a cooling compartment for refrigerating various foods. To maintain proper insulation, users typically don't open the refrigerator for extended periods. This lack of fresh air in the cooling compartment leads to the accumulation of various odors, severely impacting user experience.

[0004] In related technologies, to remove odors from refrigerators, it is common practice to place absorbent materials with strong adsorption capacity inside the refrigerator, such as activated carbon. However, this method usually has a limited adsorption lifespan and needs to be replaced after long-term use. Once the adsorption is saturated, it becomes ineffective and is detrimental to human health. Summary of the Invention

[0005] The purpose of this application is to resolve the above-mentioned problems and other issues.

[0006] The purpose of this application is also to enable the introduction of fresh air and the exhaust of stale air into the refrigerated room.

[0007] The purpose of this application is also to ensure that when fresh air transportation is stopped, the refrigerator foam layer forms a complete insulation structure, which can keep the refrigerator warm.

[0008] The purpose of this application is not limited to the purposes mentioned above, and those skilled in the art can clearly understand other purposes not mentioned from the following description.

[0031] When the second bubble layer slider moves to the fourth position, the second bubble layer slider can be offset from the opening of the second exhaust section.

[0032] The refrigerator also includes the compressor compartment cover.

[0033] The compressor compartment cover can be located at the rear bottom of the housing.

[0034] The compressor compartment cover can be enclosed with the inner wall of the box to form a compressor compartment.

[0035] A compressor may be installed in the compressor compartment.

[0036] The top wall of the compressor compartment cover can form the bottom wall of the exhaust passage, and the bottom of the second exhaust section and the compressor compartment can be selectively connected.

[0037] The exhaust passage may also include a fourth exhaust section located on top of the compressor compartment cover.

[0038] The fourth exhaust section can be located at the bottom of the second exhaust section and communicate with it.

[0039] A vent hole may be provided on the top of the compressor compartment cover at the position corresponding to the fourth exhaust section.

[0040] The fresh air module may also include a third bubble layer slider.

[0041] The third bubble layer slider is movably disposed within the fourth exhaust section, and the third bubble layer slider can cover the vent hole.

[0042] The portion of the foamed layer located at the top of the compressor compartment cover may form a cavity.

[0043] The two ends of the cavity can be connected to the inner wall of the box and the outer wall of the box liner.

[0044] The fresh air module may include a frame.

[0045] The frame can be embedded in the cavity.

[0046] The fresh air fan can be installed inside the frame.

[0047] The area within the frame where the fresh air fan can be installed forms the second exhaust section.

[0048] The frame may be equipped with a first fixed bubble layer block located at the top of the fresh air fan, which is connected to the top wall of the cavity.

[0049] The first exhaust section and the third exhaust section can be formed on both sides of the frame located in the front-to-back direction of the fresh air fan.

[0050] The fourth exhaust section can be formed within the frame on the bottom side of the fresh air fan.

[0051] The fresh air module may also include a second fixed foam layer block.

[0052] The second fixed bubble layer block and the third bubble layer slider can be set in the same layer.

[0053] The first exhaust section, the third exhaust section and the fourth exhaust section may all be equipped with slide rails.

[0054] The first bubble layer slider, the second bubble layer slider, and the third bubble layer slider may be provided with sliding parts that cooperate with the slide rail, so that they can move along their respective corresponding slide rails.

[0057] An evaporator may be installed inside the refrigeration duct, and the portion of the exhaust channel that penetrates the liner is located at the bottom side of the evaporator.

[0058] A method for controlling fresh air intake in a refrigerator, used to control the refrigerator, includes the following steps:

[0059] The system detects operating parameters, and when these parameters meet preset conditions, the fresh air mode can be activated.

[0060] The refrigeration compartment is pre-cooled, and the compressor inside the refrigerator is controlled to continue working until the real-time temperature inside the refrigeration compartment is at least 2°C lower than the preset temperature.

[0061] Control the first bubble layer slider to move it to the second position, start the fresh air fan to rotate forward, so that the fresh air fan introduces fresh air from outside the box into the refrigeration room.

[0062] After the fresh air fan rotates forward for a first time, it can be reversed for a second time to exhaust the old air in the refrigeration room to the outside of the box, and control the first bubble layer slider to move to the first position.

[0063] After the fresh air fan rotates forward for a first time, and then stops for a third time, the fresh air fan can be restarted to reverse the direction for a second time.

[0064] The details of other embodiments are included in the detailed description and the accompanying drawings.

[0065] According to at least one embodiment of this application, by introducing a fresh air module into the foam layer on the back side of the refrigerator, fresh air can be introduced into the refrigeration compartment and old air can be exhausted, keeping the refrigerator refrigeration compartment fresh and greatly improving the user experience.

[0066] According to at least one embodiment of this application, the opening of the exhaust channel is controlled by setting a first foam layer slider and controlling the movement of the first foam layer slider, so that it can be used for fresh air input or old air exhaust. When fresh air does not need to be introduced, the first foam layer slider can be moved to close the exhaust channel. At this time, the first foam layer slider, as part of the foam layer, can isolate the refrigeration chamber from the outside of the cabinet, so as to maintain the temperature inside the refrigeration chamber.

[0067] According to at least one embodiment of this application, when the fresh air transport is stopped, the first foam layer slider can move to cover the opening of the second exhaust section, so that the refrigerator foam layer forms a complete heat preservation structure, which can keep the refrigerator warm.

[0068] According to at least one of the embodiments of this application, this refrigerator only needs to add a fresh air module in the foam layer, which is highly versatile and applicable to most refrigerators. Attached Figure Description

Detailed Implementation

[0077] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0078] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0079] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0080] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0081] In related technologies, to remove odors from refrigerators, highly absorbent materials with strong adsorption capacity, such as activated carbon, are usually placed inside the refrigerator to absorb the odors. However, this method usually has a limited adsorption lifespan, requiring replacement after prolonged use. Once saturated, the adsorption becomes ineffective and is detrimental to human health. To address this problem, this application proposes a refrigerator and a method for controlling fresh air in a refrigerator.

[0082] For ease of understanding, the side of the refrigerator facing the user for operation is called the front side of the refrigerator, and the side of the refrigerator facing away from the user is called the rear side of the refrigerator.

[0083] See Figure 1 A refrigerator may include a cabinet 100. The cabinet 100 is the outer shell structure of the refrigerator, used to house other components, such as the liner 200 and the refrigeration system. The cabinet 100 may be rectangular, or other shapes.

[0084] In some embodiments, the refrigerator may include a liner 200. The liner 200 is disposed within the body 100, and a refrigeration compartment 210 with a front opening may be formed within the liner 200. Cold air circulates within the refrigeration compartment 210, thereby maintaining the refrigeration compartment 210 at a low temperature for refrigerating or freezing various items. The opening of the refrigeration compartment 210 allows a user to access items.

[0085] In some embodiments, the refrigeration compartment 210 may include a refrigerator compartment and a freezer compartment. The temperature inside the freezer compartment is below zero and is low, and is mostly used to store meat that needs to be stored for a long time. The temperature inside the refrigerator compartment is higher than that inside the freezer compartment, and can be set between 2°C and 8°C, and is mostly used to store fruits and vegetables needed for daily life.

[0086] In some embodiments, a refrigeration air duct 220 may be provided on the rear side of the freezer compartment. A duct cover may be provided on the rear side of the freezer compartment, and the duct cover and the rear wall of the freezer compartment enclose the refrigeration air duct 220. Air outlets 250 may be spaced at intervals along the vertical direction of the housing 100 on the duct cover, and a return air inlet 240 may be provided at the bottom of the duct cover. Cold air flows from the air outlets 250 into the freezer compartment and returns to the refrigeration air duct 220 from the return air inlet 240 at the bottom. A refrigeration fan 230 may be provided inside the refrigeration air duct 220. The refrigeration fan 230 facilitates the flow of cold air from the return air inlet 240 to the air outlets 250, accelerating the circulation of cold air within the freezer compartment.

[0087] In some embodiments, the refrigerator may include a door. The door is rotatably connected to the front of the refrigerator body 100 to open or close the cooling compartment 210. When the door is closed, it covers the front opening of the cooling compartment 210, thus sealing the interior of the cooling compartment 210, facilitating the low-temperature preservation of items and preventing cold air leakage. When the door is open, it allows the user to easily access items.

[0088] In some embodiments, the refrigerator compartment and the freezer compartment may each have a corresponding refrigerator compartment door and freezer compartment door to be opened or closed accordingly.

[0089] In some embodiments, the refrigerator compartment and the freezer compartment may be spaced apart along the vertical direction of the cabinet 100 or spaced apart along the horizontal direction of the cabinet 100, thereby forming a double-door refrigerator or a side-by-side refrigerator, without limitation.

[0090] In some embodiments, the refrigerator may include a refrigeration system for providing cooling capacity to the refrigerator. The refrigeration system may include a compressor 520, an evaporator 530, and a condenser.

[0091] In some embodiments, the refrigerator may include a compressor compartment cover 500. The compressor compartment cover 500 may be a semi-enclosed structure, located at the rear bottom of the cabinet 100, forming a compressor compartment 510 with the inner wall of the cabinet 100. The compressor compartment 510 is separated from the refrigeration compartment 210, and the compressor 520 and condenser described above may be installed in the compressor compartment 510. The evaporator 530 may be installed in the refrigeration air duct 220 in the freezer compartment, and located upstream of the refrigeration fan 230. The compressor 520, condenser, and evaporator 530 may be connected by a capillary tube through which refrigerant flows. The specific working principle of the refrigeration system will not be described in detail here.

[0092] In some embodiments, a foam layer 600 may be formed between the refrigerator liner 200 and the refrigerator body 100. By providing the foam layer 600, the heat transfer between the refrigerator's cooling compartment 210 and the outside can be reduced, helping the refrigerator to more effectively maintain the low temperature within the cooling compartment 210 and reduce energy consumption. The foaming material can be made of polyurethane or polystyrene. The foaming material is injected into the refrigerator body 100 using appropriate equipment, and under certain conditions, the foaming material forms the foam layer 600, filling the area between the refrigerator body 100 and the refrigerator liner 200.

[0093] In some embodiments, the foam layer 600 may form an exhaust channel 300 that penetrates the liner 200 and the housing 100. The two ends of the exhaust channel 300 may be connected to the outside of the housing 100 and the inside of the cooling room 210, thereby facilitating the introduction of fresh air and the exhaust of old air.

[0094] See Figure 2 In some embodiments, the exhaust passage 300 may include a first exhaust section 310. The exhaust passage 300 may include a second exhaust section 320. The first exhaust section 310 and the second exhaust section 320 may extend sequentially along the front-rear direction of the housing 100, the opening of the first exhaust section 310 is larger than the opening of the second exhaust section 320, and the bottom walls of the first exhaust section 310 and the second exhaust section 320 may be on the same horizontal plane.

[0095] In some embodiments, the refrigerator may include a fresh air module 400. The fresh air module 400 may include a fresh air fan 410, which is disposed within the second exhaust section 320. By disposing of the fresh air fan 410, air can circulate in the exhaust channel 300, and by controlling the rotation direction of the fresh air fan 410, the flow direction of air within the exhaust channel 300 can be controlled.

[0096] In some embodiments, the fresh air module 400 may include a first foam layer slider 420. The first foam layer slider 420 may be block-shaped and capable of covering the opening of the second exhaust section 320. The first foam layer slider 420 is larger than or equal to the opening of the second exhaust section 320. The first foam layer slider 420 is movably disposed within the first exhaust section 310 to control the opening and closing of the second exhaust section 320. The first foam layer slider 420 and the foam layer 600 may be made of the same material, and the first foam layer slider 420 may be part of the foam layer 600, thereby providing a certain heat insulation effect.

[0097] In some embodiments, the first bubble layer slider 420 is movable between a first position and a second position. When the first bubble layer slider 420 moves to the first position, it covers the opening of the second exhaust section 320 to close the exhaust passage 300, at which point the fresh air fan 410 can be in a closed state.

[0098] In some embodiments, when the first bubble layer slider 420 moves to the second position, the opening of the first bubble layer slider 420 is misaligned with the opening of the second exhaust section 320, and the exhaust passage 300 is unobstructed. At this time, the fresh air fan 410 can rotate, introducing fresh air from outside the housing 100 into the refrigeration chamber 210. After a period of time, the fresh air fan 410 can reverse, exhausting the old air in the refrigeration chamber 210 to outside the housing 100.

[0099] In some embodiments, the opening of the exhaust channel 300 is controlled by moving the first foam layer slider 420, which can then be used for fresh air intake or stale air exhaust. When fresh air is not required, the first foam layer slider 420 can be moved to close the exhaust channel 300. In this case, the first foam layer slider 420, as part of the foam layer 600, can isolate the refrigeration chamber 210 from the outside of the housing 100, thereby maintaining the temperature inside the refrigeration chamber 210.

[0100] In some embodiments, when the opening of the first exhaust section 310 is at least twice the size of the opening of the second exhaust section 320, the first bubble layer slider 420 can be the same size as the opening of the second exhaust section 320. In this way, the first bubble layer slider 420 can just cover the opening of the second exhaust section 320 in the first position, and can be completely offset from the opening of the second exhaust section 320 in the second position, so that the flow rate of the second exhaust section 320 is greater and the fresh air intake and old air exhaust are faster.

[0101] In some embodiments, the exhaust passage 300 may include a third exhaust section 330. The third exhaust section 330 is connected to the end of the second exhaust section 320 that is away from the first exhaust section 310. The third exhaust section 330 and the first exhaust section 310 are located on both sides of the second exhaust section 320. For example, if the first exhaust section 310 is close to the housing 100, then the third exhaust section 330 is close to the inner liner 200. Their positions may also be reversed.

[0102] In some embodiments, the opening of the third exhaust section 330 may be larger than the opening of the second exhaust section 320, and the bottom wall of the third exhaust section 330 may be on the same plane as the bottom wall of the second exhaust section 320. The third exhaust section 330 and the first exhaust section 310 may be symmetrically arranged with respect to the second exhaust section 320.

[0103] In some embodiments, the fresh air module 400 may include a second foam layer slider 430. The second foam layer slider 430 may be block-shaped and capable of covering the opening of the second exhaust section 320. The second foam layer slider 430 is larger than or equal to the opening of the second exhaust section 320. The second foam layer slider 430 is movably disposed within the third exhaust section 330 to control the opening and closing of the second exhaust section 320. The second foam layer slider 430 and the foam layer 600 may be made of the same material, and the second foam layer slider 430 may be part of the foam layer 600, thereby providing a certain heat insulation effect.

[0104] In some embodiments, the second bubble layer slider 430 can move between a third position and a fourth position. When the second bubble layer slider 430 moves to the third position, the second bubble layer slider 430 covers the opening of the second exhaust section 320 to close the exhaust passage 300. At this time, the fresh air fan 410 can be in the off state.

[0105] In some embodiments, when the second bubble layer slider 430 moves to the fourth position, the second bubble layer slider 430 is offset from the opening of the second exhaust section 320. If the first bubble layer slider 420 moves to the second position at the same time, the exhaust channel 300 is unobstructed, and the fresh air fan 410 can be turned on to exhaust fresh air into the cooling room 210 or exhaust old air from the cooling room 210 to the outside of the housing 100.

[0106] In some embodiments, by setting the second foam layer slider 430, the first foam layer slider 420 and the second foam layer slider 430 can both cover the openings at both ends of the second exhaust section 320, so that the fresh air fan 410 and the cooling room 210 are better isolated and the foam layer 600 has a better heat preservation effect.

[0107] In some embodiments, when the opening of the third exhaust section 330 is at least twice the size of the opening of the second exhaust section 320, the second bubble layer slider 430 can be the same size as the opening of the second exhaust section 320. In this way, the second bubble layer slider 430 can just cover the opening of the second exhaust section 320 in the third position, and can be completely offset from the opening of the second exhaust section 320 in the fourth position, so that the flow rate of the second exhaust section 320 is greater and the fresh air intake and old air exhaust are faster.

[0108] In some embodiments, the second bubble layer slider 430 may have the same structure as the first bubble layer slider 420.

[0109] In some embodiments, the exhaust channel 300 can be disposed on the top of the press chamber cover 500, and the top wall of the press chamber cover 500 forms the bottom wall of the exhaust channel 300, so that the exhaust channel 300 can be easily formed with the press chamber cover 500 as the bottom.

[0110] In some embodiments, the bottom of the second exhaust section 320 and the compressor chamber 510 may be selectively connected. When the second exhaust section 320 and the compressor chamber 510 are connected, old air can be discharged into the compressor chamber 510 while the fresh air fan 410 is discharging old air outward, thereby using the lower temperature of the old air to cool and dissipate heat from the compressor 520 inside the compressor chamber 510.

[0111] In some embodiments, a vent hole may be provided on the top of the compressor compartment cover 500 at the position corresponding to the second exhaust section 320. The vent hole can be selectively opened or closed. The vent hole is positioned opposite to the compressor 520 in the compressor compartment 510, so that the old air can be blown directly to the compressor 520, thereby improving the heat dissipation efficiency.

[0112] In some embodiments, the exhaust passage 300 may include a fourth exhaust section 340 disposed on the top of the compressor compartment cover 500. The fourth exhaust section 340 may extend in the front-rear direction of the housing 100, and the fourth exhaust section 340 is located at the bottom of and communicates with the second exhaust section 320, through which old air may flow from the second exhaust section 320 to the fourth exhaust section 340.

[0113] In some embodiments, the fresh air module 400 may include a third bubble layer slider 440, which is block-shaped. The third bubble layer slider 440 is movably disposed within the fourth exhaust section 340 and can move along the front-rear direction of the housing 100. The third bubble layer slider 440 can cover the vent hole, and the opening of the third bubble layer slider 440 is greater than or equal to that of the vent hole. By controlling the movement of the third bubble layer slider 440, selective communication between the second exhaust section 320 and the compressor chamber 510 can be achieved.

[0114] See Figure 3In some embodiments, when the third bubble layer slider 440 covers the vent, and the first bubble layer slider 420 and the second bubble layer slider 430 are located in the second position and the fourth position respectively, the fresh air fan 410 can introduce fresh air from outside the housing 100 into the refrigeration room 210 along the first exhaust section 310, the second exhaust section 320 and the third exhaust section 330.

[0115] See Figure 4 In some embodiments, when the third bubble layer slider 440 moves to be offset from the vent, the compressor chamber 510 and the second exhaust section 320 are connected. When the first bubble layer slider 420 is in the first position and the second bubble layer slider 430 is in the fourth position, the fresh air fan 410 discharges the old air in the refrigeration chamber 210 directly from the second exhaust section 320 to the fourth exhaust section 340 and enters the compressor chamber 510 through the vent.

[0116] In some embodiments, the fresh air module 400 may include a frame 700, which may be a rectangular frame structure. By setting the frame 700, the fresh air fan 410, the first foam layer slider 420, the second foam layer slider 430, and the third foam layer slider 440 can be placed inside the frame 700, and then the frame 700 is placed in the foam layer 600, which facilitates the installation of each component.

[0117] In some embodiments, the portion of the foamed layer 600 located at the top of the press chamber cover 500 may have a cavity, and the frame 700 is embedded in the cavity. Alternatively, the frame 700 can be placed on top of the press chamber cover 500 first, and then the foamed layer 600 can be formed, thus creating a cavity at the location of the frame 700. Or, the foamed layer 600 can be formed first, and then a cavity can be excavated at the corresponding location, with the frame 700 then embedded in the cavity.

[0118] In some embodiments, a second exhaust section 320 is formed in the area within the frame 700 where the fresh air fan 410 is located. A first fixed bubble layer block 450, which is connected to the top wall of the cavity, may be provided at the top of the fresh air fan 410 within the frame 700. A first exhaust section 310 and a third exhaust section 330 are formed on both sides of the fresh air fan 410 in the front-rear direction within the frame 700, respectively. A fourth exhaust section 340 is formed at the bottom side of the fresh air fan 410 within the frame 700.

[0131] In summary, in this embodiment, different ventilation paths can be formed by flexibly moving the positions of the first bubble layer slider 420, the second bubble layer slider 430, and the third bubble layer slider 440. These paths can be used for fresh air input or for old air exhaust. The old air can be exhausted into the compressor chamber 510 to dissipate heat from the compressor 520, thus making reasonable use of the old air.

[0132] In this embodiment, forced convection can be achieved through the fresh air fan 410 and the refrigeration fan 230, allowing fresh air to quickly enter the refrigeration chamber 210. At the same time, the old air in the refrigeration chamber 210 can be quickly discharged to the compressor chamber 510, completely eliminating the unpleasant odor in the refrigeration chamber 210 and improving the user experience.

[0133] In this embodiment, simply adding a fresh air module 400 to the foam layer 600 at the rear of the refrigerator is sufficient to introduce fresh air and exhaust old air. It is highly versatile and applicable to most refrigerators.

[0134] See Figure 5 This application also proposes a method for controlling the fresh air intake of a refrigerator, which includes the following steps:

[0135] Step S100: Detect operating parameters. When the operating parameters meet the preset conditions, the fresh air mode can be turned on.

[0136] The operating parameters may include the interval between opening and closing the refrigerator door. When the door is opened, outside heat will enter the refrigeration compartment 210, causing the temperature of the stored items to rise. Combined with the heat brought by the fresh air, the temperature of the items will rise further, which is not conducive to the preservation of the items. Therefore, the interval between opening and closing the refrigerator door should be greater than or equal to 2 hours. The fresh air mode can only be turned on if the door is not opened or closed for at least 2 hours. The heat in the refrigeration compartment 210 is basically only affected by the fresh air.

[0137] In some embodiments, operating parameters may include the 24-hour refrigerator operating rate. When the 24-hour refrigerator operating rate is greater than 90%, the refrigerator may be overloaded due to opening and closing the door, placing hot food inside, or high ambient temperature, which may not be enough to support the heat brought by the fresh air. In this case, turning on the fresh air mode may cause the refrigerator to run continuously without reaching the preset temperature. Therefore, when the 24-hour refrigerator operating rate is ≤90%, the fresh air mode can be turned on.

[0138] In some embodiments, operating parameters may include the outdoor temperature of the enclosure 100. Since the fresh air temperature is equal to the outdoor temperature of the enclosure 100, a higher outdoor temperature will enter the cooling chamber 210 with the fresh air, increasing the heat load inside the enclosure. A higher fresh air temperature will also cause frost to form on the surface of food, affecting the appearance and taste of the food. Therefore, when the outdoor temperature of the enclosure 100 is ≤25℃, the fresh air mode can be turned on.

[0139] In some embodiments, operating parameters may include the refrigerator defrost interval. The defrost time is typically about 0.5 hours, and the time it takes for the food temperature in the cooling compartment 210 to drop to -18°C varies between 2 and 3.5 hours depending on the amount of food. That is, after defrosting is started, the food temperature can usually drop below -18°C within 4 hours. Therefore, if the defrost interval is greater than or equal to 4 hours, the fresh air mode can be activated.

[0140] In some embodiments, the fresh air mode can be turned on when the interval between opening and closing the refrigerator door, the 24-hour refrigerator operating rate, the outdoor temperature of the refrigerator body at 100°C, and the defrosting interval of the refrigerator all meet the preset conditions.

[0141] Step S200: Pre-cool the refrigeration compartment 210 and control the compressor 520 in the refrigerator to continue working until the real-time temperature in the refrigeration compartment 210 is 2°C lower than the preset temperature.

[0142] Based on the above, since the fresh air entering the cooling compartment 210 brings heat, it will raise the temperature inside the cooling compartment 210, which is detrimental to the stored items. Therefore, it is necessary to pre-cool the cooling compartment 210. The refrigerator compressor 520 will continue to operate until the real-time temperature inside the cooling compartment 210 is at least 2°C lower than the preset temperature to offset the heat brought by the fresh air. This preset temperature can be the temperature inside the cooling compartment 210 set by the user on the control panel. The real-time temperature inside the cooling compartment can also be 3°C or 3.5°C lower than the preset temperature, depending on the actual setting.

[0143] Step S300: Control the first bubble layer slider 420 to move it to the second position, start the fresh air fan 410 to rotate forward, so that the fresh air fan 410 introduces fresh air from outside the box 100 into the refrigeration room 210.

[0144] Based on the above, after pre-cooling is completed, fresh air can be introduced. By controlling the movement of the first bubble layer slider 420, the exhaust channel 300 is unobstructed, and the fresh air fan 410 rotates in the forward direction, which can draw fresh air into the cooling room 210, thus realizing the introduction of fresh air.

[0145] In some embodiments, after the fresh air fan 410 rotates forward, the refrigeration fan 230 is turned off, which can effectively prevent the high-temperature fresh air from entering the refrigeration duct 220 and being blown directly onto the food surface by the refrigeration fan 230, causing the food to soften.

[0146] Step S400: After the fresh air fan 410 rotates forward for a first time, the fresh air fan 410 is reversed for a second time to exhaust the old air in the refrigeration chamber 210 to the outside of the box 100, and the first bubble layer slider 420 is controlled to move to the first position.

[0147] Based on the above, when the fresh air fan 410 rotates forward, it draws fresh air from outside the housing 100 into the cooling room 210. After the fresh air fan 410 rotates forward for the first time, the fresh air enters the cooling room 210 and undergoes forced convection heat exchange with the evaporator 530 to form low-temperature fresh air. This first time can be 10 seconds or 12 seconds, depending on the actual setting.

[0148] After the fresh air fan 410 rotates forward for a first time, it reverses for a second time. Upon completion of the second time, the first bubble layer slider 420 moves to the first position, covering the opening of the second exhaust section 320, thus closing the exhaust passage 300 and forming a sealed, insulated structure. The reverse rotation of the fresh air fan 410 is relative to its forward rotation and changes the direction of the drawn air. For example, if the fresh air fan 410 reverses, it can draw the stale air from the refrigerated compartment 210 to the outside of the enclosure 100, expelling the stale air. The second time can be 10 seconds or 12 seconds, depending on the actual settings.

[0149] See Figure 6 In this embodiment, the refrigerator fresh air control method may further include the following steps:

[0150] Step S410: After the fresh air fan 410 rotates forward for the first time, the fresh air fan 410 stops for the third time, and then the fresh air fan 410 is turned on again, causing the fresh air fan 410 to rotate in reverse for the second time.

[0151] Based on the above, the third time the fresh air fan 410 stops is to allow sufficient heat exchange between the fresh air and the evaporator 530, turning the fresh air into cool air, thus preventing excessive heat from being brought into the cooling room 210. This third time can be 5 seconds or 6 seconds, depending on the actual settings.

[0152] In some embodiments, after the fresh air fan 410 has been shut down for three hours, the refrigeration fan 230 can be turned on for a certain period of time so that the cooled fresh air can be blown into the refrigeration room 210 as soon as possible to provide fresh air to the refrigeration room 210.

[0153] In some embodiments, the fresh air fan 410 rotating forward, the fresh air fan 410 stopping, the refrigeration fan 230 starting, the refrigeration fan 230 stopping, and the fresh air fan 410 reversing can be a cycle of fresh air introduction and old air exhaust. After the refrigerator cycles multiple times, such as more than 3 times, the unpleasant odor in the refrigeration compartment 210 can be completely removed.

[0154] Step S510: Enter fresh air standby mode, compressor 520 and refrigeration fan 230 start at maximum speed until the temperature inside the refrigeration room 210 reaches the shutdown temperature.

[0155] Based on the above, after the fresh air mode is activated once, the temperature inside the refrigerated room 210 will rise slightly. In order to preserve food, it is necessary to quickly cool it down by using strong cooling.

[0156] Step S520: After the refrigerator continues to run for four hours, it enters defrosting mode.

[0157] Based on the above, the fourth time can be 4 hours, 6 hours, etc. After the refrigerator has been running for the fourth time, it will enter defrost mode and resume normal control.

[0158] Step S530: After 24 hours, determine whether the operating parameters meet the preset conditions. If they do, turn on the fresh air mode.

[0159] Based on the above, the fresh air mode is executed once every 24 hours. This ensures that the refrigeration room 210 has a fresh odor while minimizing the impact on the food temperature inside.

[0160] In summary, this control method can intelligently control the introduction of fresh air and the exhaust of old air, keeping the odor inside the refrigerator fresh at all times, with minimal impact on the food stored in the refrigeration compartment 210, thus meeting users' health needs and improving user experience.
