Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, for example, to a control method and device for a refrigerator, and a refrigerator. Background Art

[0002] With the upgrading of the refrigerator consumption market, high-end and large refrigerators are becoming more and more popular among consumers. However, with the increase in the volume of refrigerators, consumers have put forward new requirements for the storage and preservation of food, that is, to add drawers with freezing and moisturizing functions in the freezer to meet the freezing and high-humidity storage environment for some meat rolls, ready-to-eat foods and some pre-prepared dishes. The drawers with freezing and moisturizing functions can prevent cold air from blowing directly on the food during the refrigeration process, and the moisture-permeable membrane components with humidity control can maintain the food in a high-humidity environment, thereby effectively preventing the food from drying out and other phenomena that damage the nutrient loss of the food.

[0003] However, the moisturizing drawer with the function of preserving food in the related art can only be used in the refrigerator compartment of the refrigerator. If the existing moisturizing drawer is directly used in the freezer compartment, since the existing freezer compartment only detects the temperature, that is, only guarantees the temperature in the compartment without considering the humidity, frost will form on the top of the moisturizing drawer in the freezer compartment, thereby affecting the moisture permeability of the moisture permeable component and further affecting the humidity in the drawer.

[0065] The moisturizing drawer with the function of preserving food in the related art can only be applied to the cold storage room of the refrigerator. If the existing moisturizing drawer is directly applied to the freezing room, frost will occur on the top of the moisturizing drawer.

[0066] Combination Figures 1 to 23As shown, the refrigerator of this embodiment includes an inner tank, a main fan and a drawer assembly. The drawer assembly is arranged in the inner tank 10. The side wall of the inner tank is constructed with a first air port 101 and a second air port 102. The first air port 101 is located above the drawer assembly. The airflow blown out by the main fan through the first air port 101 forms a main air path above the drawer assembly; the second air port 102 corresponds to the drawer assembly, and the airflow blown out by the main fan through the second air port 102 is used to form an auxiliary air path in the drawer assembly or to accelerate the airflow velocity of the auxiliary air path.

[0067] The inner liner 10 and the drawer assembly provided in this embodiment can be used in a freezer compartment to meet the user's need to keep the food in the freezer compartment moisturized and fresh. However, it should be noted that the inner liner 10 and the drawer assembly provided in this embodiment are not limited to the freezer compartment, but can also be used in a refrigeration compartment or a variable temperature compartment.

[0068] The drawer assembly includes a drawer cover 30 and a drawer body 20 that are slidably connected. The drawer cover 30 is provided with a moisture permeable assembly 40. The top of the drawer assembly is constructed with a first ventilation portion 100 and a second ventilation portion 200 that are relatively arranged. The airflow blown out of the first air outlet or the second air outlet flows into the drawer body 20 through the first ventilation portion 100 and flows out from the second ventilation portion 200. The airflow flowing into the drawer body 20 forms an auxiliary air path on the lower surface of the drawer cover 30, and the auxiliary air path is used to prevent frost on the lower surface of the moisture permeable assembly 40.

[0069] The inner wall of the inner liner 10 is provided with an air supply duct, and a main fan is provided in the air supply duct. The air flow blown by the main fan flows through the air supply duct and is blown out from the first air outlet and the second air outlet to the compartment to play a cooling role. It should be noted that the air flow blown out of the air outlet of the inner liner 10 is the same in terms of temperature and humidity. In this article, only the different positions produce different effects, and for the convenience of description, the air outlets are distinguished and named, namely the first air outlet 101 and the second air outlet 102.

[0070] The drawer assembly is arranged in the inner container 10, and is slidably connected to the drawer body 20 through the drawer cover 30. The drawer cover is arranged on the drawer body 20, so that a relatively closed space is formed inside the drawer. In this way, it is possible to prevent the airflow blown out of the air outlet from directly entering the drawer and acting on the surface of the food, causing serious moisture loss of the food, and affecting the edible taste and quality of the food.

[0071] The drawer assembly including the drawer cover 30 can maintain the food in the drawer in a high humidity environment, but if the humidity exceeds the preset value, it will not only affect the taste and quality of the food in the drawer, but also reduce the freezing and refrigeration effect of the food. Therefore, the drawer cover 30 with the moisture permeable component 40 provided in this embodiment can not only achieve the purpose of covering the drawer to form a closed space, but also adjust the humidity of the environment in the drawer through the moisture permeable component 40, ensuring that the food in the drawer is in a humidity environment that can take into account both the preservation and freezing effects.

[0072] In this embodiment, the first ventilation part 100 and the second ventilation part 200 are constructed at the top of the drawer assembly, so that the airflow blown out of the air outlet can flow through the inside of the drawer body 20. Based on the first ventilation part 100 and the second ventilation part 200 being located at the top of the drawer assembly, the airflow flowing into the drawer body 20 flows along the lower surface of the drawer cover 30 to form an auxiliary air path, i.e., a parallel flow parallel to the drawer cover 30. The airflow flows through the lower surface of the drawer cover 30, and the water vapor located on the lower surface of the moisture permeable component 40 can be taken away, so as to avoid the condensation of water vapor on the lower surface of the moisture permeable component 40, i.e., frost, which affects the moisture permeability function of the moisture permeable component 40, and can also accelerate the humidity in the drawer to prevent the humidity from being too high. In addition, the auxiliary air path is parallel to the lower surface of the drawer cover 30, and basically does not contact the food inside the drawer body 20, thereby avoiding the direct blowing of cold air on the food, and ensuring the freshness preservation effect of the food.

[0073] The first ventilation part 100 is an air inlet, and the second ventilation part 200 is an air outlet. The first ventilation part 100 may be located at the back of the drawer assembly (i.e., the side close to the air outlet), but the first ventilation part 100 may also be located at the front of the drawer assembly. When the first ventilation part 100 is located at the back of the drawer assembly, the second ventilation part 200 is located at the front of the drawer assembly; conversely, when the first ventilation part 100 is located at the front of the drawer assembly, the second ventilation part 200 is located at the back of the drawer assembly.

[0074] When the first ventilation part 100 is located at the front of the drawer assembly, that is, the front end of the drawer assembly is inlet. The air outlet has a large air volume and a fast wind speed. The second ventilation part 200 is an air outlet. The airflow blown out of the air outlet forms a negative pressure area at the second ventilation part 200, so that the cold air can flow through the lower surface of the drawer cover 30 at a faster speed and flow out from the second ventilation part 200. In addition, the humidity in the drawer can be reduced faster.

[0075] When the first ventilation part 100 is located at the back of the drawer assembly, that is, the air enters from the back of the drawer assembly and the air exits from the front. The airflow blown out of the air outlet can directly flow into the drawer through the first ventilation part 100, and then blow out from the second ventilation part 200. Similarly, the airflow blown out of the air outlet has a faster flow rate, and the airflow can quickly flow out from the second ventilation part 200, preventing the cold air from blowing directly onto the surface of the food in the drawer, affecting the preservation effect of the food.

[0076] The auxiliary air passage formed in this embodiment can not only effectively reduce the amount of frost on the drawer cover 30, but also ensure the humidity environment inside the drawer.

[0077] The airflow blown out of the first air outlet 101 provided in this embodiment flows through the upper surface of the drawer cover 30 to form a main air path to blow away the water vapor transmitted from the moisture permeable component 40; wherein the first air outlet 101 is arranged horizontally and is higher than the drawer cover 30. Figure 1 , Figure 2 , Figure 4 and Figure 5 shown.

[0078] The first air outlet 101 can be regarded as the main air outlet of the air supply duct, and its main function is to refrigerate the space in the freezer compartment. The airflow blown out from the first air outlet 101 has a large flow rate and a fast flow rate. In the air supply stage of the air supply duct, the cold air blown out from the first air outlet 101 blows over the top of the drawer cover 30, that is, the airflow of the main air path flows over the top of the drawer cover 30, which can quickly take away the water vapor transmitted from the moisture permeable component 40, ensuring that the moisture permeable component 40 is in an efficient moisturizing state.

[0079] The horizontal air outlet setting of the first air outlet 101 can make the airflow blown out by the first air outlet 101 parallel to the drawer cover 30, thereby cooperating with the auxiliary air path so that the auxiliary air path forms a parallel flow on the lower surface side of the drawer cover 30, which not only quickly reduces the high humidity water vapor under the drawer cover 30 to prevent the risk of freezing of the drawer cover 30 due to excessive water vapor, but also prevents cold air from directly blowing on the food, thereby keeping the food fresh.

[0080] The second air outlet 102 provided in this embodiment is located below the first air outlet 101, and the second air outlet 102 is used to form an auxiliary air path or to speed up the air flow rate of the auxiliary air path. Figure 1 , Figure 2 , Figure 4 and Figure 5 shown.

[0081] The second air outlet 102 is located below the first air outlet 101 and is provided for the auxiliary air path. The air flow rate of the auxiliary air path is much smaller than the air flow rate of the main air path. Therefore, it can be considered that the flow area of ​​the second air outlet 102, i.e., the air outlet area, is smaller than the flow area of ​​the first air outlet 101.

[0082] Optionally, when the second air outlet 102 discharges air horizontally, the second air outlet 102 corresponds to the first ventilation part 100 or the second ventilation part 200 of the drawer assembly, so that the blown air flows into the drawer body 20 to form an auxiliary air path. Figure 1 and Figure 2 shown.

[0083] When the second air outlet 102 is discharging air horizontally, the second air outlet 102 is used to form an auxiliary air path. In combination with the first ventilation part 100 defined as the air inlet for the convenience of description and distinction as mentioned above, the second air outlet 102 is arranged corresponding to the first ventilation part 100, and the air flow blown out by the second air outlet 102 flows into the drawer through the first ventilation part 101. Although the air flow rate of the second air outlet 102 is not as good as that of the first air outlet 101, the flow rate of the air flow blown out from the second air outlet 102 is still relatively fast. When the air flow enters the drawer body 20, the air flow still flows forward rapidly and flows out through the second ventilation part 200 located at the front end, thereby forming a parallel wind curtain layer on the lower surface of the drawer cover 30, blowing away the water vapor on the lower surface of the drawer cover 30, thereby not only quickly reducing the high humidity water vapor under the drawer cover 30, avoiding the risk of freezing of the drawer cover 30 and the moisture permeable component 40 due to excessive water vapor, but also preventing cold air from blowing directly on the food, thereby keeping the food fresh.

[0084] Optionally, when the second air outlet 102 is vertical and discharges air downward, the second air outlet 102 is higher than the first ventilation part 100 or the second ventilation part 200 of the drawer assembly, and the second air outlet 102 is used to blow away the airflow flowing out of the drawer assembly, increase the pressure difference and speed up the airflow velocity of the auxiliary air path. Figure 4 and Figure 5 shown.

[0085] When the second air outlet 102 is vertically and downwardly discharged, the second air outlet 102 is used to speed up the air flow rate of the auxiliary air path. At this time, the air outlet of the drawer assembly is arranged close to the second air outlet 102, that is, the second ventilation part 200 is located at the back of the drawer assembly, and the first ventilation part 100 is located at the front of the drawer assembly. The second air outlet 102 is higher than the second ventilation part 200, so that the air flow flowing out of the second ventilation part 200 can be quickly blown away by the second air outlet 102, so that a certain pressure difference is formed at the second ventilation part 200, which can speed up the air flow of the auxiliary air path in the drawer to the second ventilation part 200, thereby quickly reducing the high humidity water vapor under the drawer cover 30, avoiding the risk of ice formation of the drawer cover 30 and the moisture permeable component 40 due to excessive water vapor, and can also prevent cold wind from blowing directly on the food, thereby playing a role in preserving the food.

[0086] Optionally, the refrigerator further comprises: a damper assembly 50, which is disposed at the second air outlet 102 and is used to adjust the flow area of ​​the second air outlet 102. Figures 6 to 9 shown.

[0087] The flow area of ​​the second air outlet 102 is adjusted by the damper assembly 50, that is, the air volume of the second air outlet 102 is adjusted, thereby adjusting the auxiliary air path, and further adjusting the humidity control in the drawer. The drawer assembly provided in this embodiment can not only adjust the humidity in the drawer through the moisture permeable assembly 40, but also adjust the humidity in the drawer by adjusting the air flow rate of the second air outlet 102 and the auxiliary air path. The moisture permeable assembly 40 cooperates with the auxiliary air path to ensure not only the moisture permeability effect of the moisture permeable assembly 40, but also the moisture retention and freshness preservation effect of the drawer.

[0088] Optionally, a slide rail 105 is provided at the second air outlet 102, and the air door assembly 50 includes: an air door sliding piece 501, which is slidably connected to the slide rail 105 and is used to adjust the flow area of ​​the second air outlet 102, and the end of the air door sliding piece 501 is configured with a rack portion 5011; a transmission gear 502, which is meshed and connected with the rack portion 5011; a motor 503, which is provided in the inner tank 10 and is transmission-connected with the transmission gear 502, and the motor 503 drives the transmission gear 502 to rotate, thereby driving the air door sliding piece 501 to move back and forth in a straight line, thereby adjusting the flow area of ​​the second air outlet 102. Figures 6 to 9 shown.

[0089] The ventilation area of ​​the second air outlet 102 is shielded by the air door sliding piece 501, so that the flow area of ​​the second air outlet 102 can be adjusted. The motor 503 drives the transmission gear 502 to rotate, and the transmission gear 502 is engaged with the rack portion 5011 of the air door sliding piece 501, thereby driving the air door sliding piece 501 to move back and forth along the slide rail 105 in a straight line, thereby adjusting the flow area of ​​the second air outlet 102.

[0090] In order to more efficiently adjust the flow area of ​​the second air outlet 102, optionally, the second air outlet 102 includes a plurality of first vents, and the damper sliding piece 501 is also configured with a plurality of second vents 5012 that match the first vents; when the second vents 5012 correspond to the first vents, the second air outlet 102 is opened; when the area between the adjacent second vents 5012 corresponds to the first vents, the second air outlet 102 is closed. In this way, the limitation that the damper sliding piece 501 needs too much moving space to completely close the second air outlet 102 when sliding from one end of the second air outlet 102 to the other end can be overcome.

[0091] Combination Fig. 20 As shown, the embodiment of the present disclosure provides a control method for a refrigerator, comprising:

[0092] S01, when the first air outlet and the second air outlet are both opened to discharge air, the processor obtains the temperature value in the drawer component;

[0093] S02, when the temperature value of the drawer assembly is higher than the shutdown temperature of the refrigerator, the processor obtains the humidity value in the drawer assembly, and controls the switch of the second air outlet according to the ratio of the humidity value of the drawer assembly to the first humidity threshold value;

[0094] S03, when the temperature value of the drawer assembly is lower than or equal to the shutdown temperature of the refrigerator, the processor controls the main fan to turn off.

[0095] In the disclosed embodiment, air is discharged through the first air outlet and the second air outlet to cool the room where the drawer assembly is located; by achieving different conditions, the switch of the second air outlet, that is, the on-off of the auxiliary air path, is controlled, which helps to control the humidity in the drawer assembly and ensure the freshness of the food in the drawer; in addition, when the temperature in the drawer assembly reaches the shutdown temperature, the main fan is controlled to be turned off, which helps to save energy and reduce consumption. It can also avoid excessive frost on the top of the drawer assembly due to too low temperature, which affects the humidity control effect.

[0096] It should be noted that the temperature value of the drawer assembly is higher than the shutdown temperature of the refrigerator. It can be understood that the temperature of the drawer assembly has not yet reached the temperature required for the compartment to reach when the compressor stops. When the temperature value of the drawer assembly is higher than the shutdown temperature of the refrigerator, the main fan is in the on state, and the first air outlet and the second air outlet are also in the air outlet state. In this way, the first air outlet and the second air outlet continuously discharge air to cool the compartment and reduce the temperature in the compartment and the drawer assembly. At this time, compare the humidity value in the current drawer assembly with the first humidity threshold, where the first humidity threshold is the preset minimum humidity value to be reached in the drawer assembly; according to the comparison result, control the switch of the second air outlet, that is, control the on and off of the auxiliary air path, so as to ensure the humidity requirements in the drawer assembly.

[0097] When the temperature value of the drawer assembly is lower than or equal to the shutdown temperature of the refrigerator, the main fan is controlled to be turned off, so that the first air outlet and the second air outlet no longer discharge air, thereby preventing the temperature in the compartment and the drawer assembly from continuing to drop, which is not only not conducive to energy saving and consumption reduction, but also affects the stability of the humidity environment in the drawer assembly based on the temperature.

[0098] Optionally, when the temperature value of the drawer assembly is higher than the shutdown temperature of the refrigerator, the humidity value in the drawer assembly is obtained, and the switch of the second air vent is controlled according to the ratio of the humidity value of the drawer assembly to the first humidity threshold, including: when the humidity value of the drawer assembly is lower than or equal to the first humidity threshold, the second air vent is controlled to be closed.

[0099] The first humidity threshold is the preset minimum humidity value to be reached in the drawer assembly; when the humidity value of the drawer assembly is lower than or equal to the first humidity threshold, the second air outlet is controlled to be closed, that is, the auxiliary air path is controlled to be disconnected, and the airflow can only form weak convection in the drawer assembly, which can delay the leakage of water vapor in the drawer assembly to the outside, that is, avoid the reduction of humidity in the drawer assembly, and ensure the humidity level in the drawer assembly.

[0100] Optionally, when the temperature value of the drawer assembly is higher than the shutdown temperature of the refrigerator, the humidity value in the drawer assembly is obtained, and the switch of the second air vent is controlled according to the ratio of the humidity value of the drawer assembly to the first humidity threshold value. It also includes: when the humidity value of the drawer assembly is higher than the first humidity threshold value, the second air vent is maintained open.

[0101] When the humidity value of the drawer assembly is higher than the first humidity threshold, it can be understood that there is still room for the humidity in the drawer assembly to be reduced. The overall humidity in the drawer assembly is too high, especially when the humidity value in the drawer assembly is higher than the shutdown temperature of the refrigerator. The humidity in the drawer assembly is too high, which is not conducive to the freezing and preservation effect of the food in the drawer. At this time, the second air outlet is kept open, that is, the auxiliary air path is maintained. The water vapor in the drawer can be taken away through the auxiliary air path, which can avoid condensation of water vapor and affect the moisture permeability of the drawer assembly on the one hand, and can also accelerate the reduction of humidity in the drawer on the other hand.

[0102] Optionally, the refrigerator further comprises a circulating fan, which is arranged above the drawer assembly and forms a circulating air path above the drawer assembly. When the circulating fan is started, the circulating fan forms a circulating air path above the drawer assembly, especially the moisture permeable assembly, so that the water vapor on the surface of the moisture permeable assembly can be blown away, thereby preventing the risk of surface icing due to poor moisture discharge on the surface of the moisture permeable assembly, thereby affecting the moisturizing effect of the drawer, and eliminating the quality risk of ice forming on the inner wall and the drawer cover due to excessive humidity inside the drawer.

[0103] Combination Fig.21 As shown, the embodiment of the present disclosure provides another control method for a refrigerator, comprising:

[0104] S01, when the first air outlet and the second air outlet are both opened to discharge air, the processor obtains the temperature value in the drawer component;

[0105] S02, when the temperature value of the drawer assembly is higher than the shutdown temperature of the refrigerator, the processor obtains the humidity value in the drawer assembly, and controls the switch of the second air outlet according to the ratio of the humidity value of the drawer assembly to the first humidity threshold value;

[0106] S03, when the temperature value of the drawer assembly is lower than or equal to the shutdown temperature of the refrigerator, the processor controls the main fan to turn off;

[0107] S04, the processor obtains the humidity value in the drawer assembly, and controls the switch of the circulation fan according to the ratio of the humidity value of the drawer assembly to the second humidity threshold.

[0108] It should be noted that the second humidity threshold is the maximum humidity value required in the drawer assembly.

[0109] In the disclosed embodiment, when the main fan is turned off, the switch of the circulation fan is controlled by comparing the humidity value in the drawer assembly with the second humidity threshold, so that when the air is stopped, it can be further determined whether it is necessary to help the drawer assembly to adjust the humidity.

[0110] Optionally, the switch of the circulation fan is controlled according to the ratio of the humidity value of the drawer assembly to the second humidity threshold, including: when the humidity value of the drawer assembly is higher than the second humidity threshold, the auxiliary fan is controlled to turn on to generate a circulating air path to remove water vapor from the drawer assembly.

[0111] The main fan is turned off, and the first and second air outlets stop supplying air. When the humidity value of the drawer assembly is higher than the second humidity threshold, the circulation fan 60 is started. The airflow generated by the circulation fan 60 can suck or blow air from the moisture permeable assembly 40 of the drawer cover 30, blow away or take away the water vapor on the surface of the moisture permeable assembly 40, and exchange it with the cold air in the freezer compartment, thereby preventing the risk of surface icing on the surface of the moisture permeable assembly 40 due to poor moisture discharge, thereby affecting the moisturizing effect of the drawer, and eliminating the quality risk of excessive humidity inside the drawer causing ice on the inner wall of the drawer and the drawer cover.

[0112] Exemplarily, when the drawer assembly is located above the freezer compartment, the top of the inner liner 10 is configured with a guide air duct 104, and the circulation fan 60 is connected to the guide air duct 104. For example, the first air outlet 101 stops supplying air, the circulation fan 60 is started, and the circulation fan 60 sucks air outward from the moisture permeable assembly 40, that is, the moisture permeable assembly 40 is located on the air inlet side of the circulation fan 60, and the air outlet side of the circulation fan 60 faces the guide air duct 104. When the circulation fan 60 is started, the airflow on the upper surface of the drawer cover 30 flows into the circulation fan 60 under the action of suction, and is blown out to the guide air duct 104. The airflow flowing out of the guide air duct 104 enters the circulation fan 60 again under the action of suction, and the cycle repeats. When the airflow circulates back and forth, the airflow flows through the upper surface of the moisture permeable assembly 40, and can take away the water vapor of the moisture permeable assembly 40 in time, so as to prevent the risk of surface icing on the surface of the moisture permeable assembly 40 due to poor moisture discharge.

[0113] Exemplarily, the first air outlet 101 stops supplying air, the circulating fan 60 is started, and the circulating fan 60 blows air from the side of the moisture permeable component 40, that is, the moisture permeable component 40 is located on the air outlet side of the circulating fan 60, and the air inlet side of the circulating fan 60 faces the guide air duct 104. When the circulating fan 60 is started, the airflow on the upper surface of the drawer cover 30 flows to the surroundings along the drawer cover 30 under the action of the fan, and then enters the circulating fan 60 through the guide air duct 104, and is then blown out by the circulating fan 60, and so on. In the case of the reciprocating flow of the airflow, the airflow flows through the upper surface of the moisture permeable component 40, and the water vapor that penetrates the moisture permeable component 40 can be blown away in time, preventing the risk of surface icing on the surface of the moisture permeable component 40 due to poor moisture discharge.

[0114] It should be noted that there is a certain gap between the circulation fan 60 and the surface of the moisture permeable component 40, so that the airflow above the drawer cover 30 can flow into the gap between the circulation fan 60 and the surface of the moisture permeable component 40, thereby blowing away or taking away the water vapor on the surface of the moisture permeable component 40.

[0115] Optionally, controlling the switch of the circulation fan according to the ratio of the humidity value of the drawer assembly to the second humidity threshold value also includes: controlling the auxiliary fan to be turned off when the humidity value of the drawer assembly is lower than or equal to the second humidity threshold value.

[0116] The main fan is turned off, and the first and second air outlets stop supplying air. When the humidity value in the drawer assembly is lower than or equal to the second humidity threshold, the auxiliary fan is controlled to be turned off, which can avoid the humidity in the drawer assembly from decreasing and keep the humidity environment in the drawer assembly balanced and stable.

[0117] Combination Fig. 22 As shown, the embodiment of the present disclosure provides another control method for a refrigerator, comprising:

[0118] S01, when the first air outlet and the second air outlet are both opened to discharge air, the processor obtains the temperature value in the drawer component;

[0119] S02, when the temperature value of the drawer assembly is higher than the shutdown temperature of the refrigerator, the processor obtains the humidity value in the drawer assembly, and controls the switch of the second air outlet according to the ratio of the humidity value of the drawer assembly to the first humidity threshold value;

[0120] S03, when the temperature value of the drawer assembly is lower than or equal to the shutdown temperature of the refrigerator, the processor controls the main fan to turn off;

[0121] S04, the processor obtains the humidity value in the drawer assembly, and controls the switch of the circulation fan according to the ratio of the humidity value of the drawer assembly to the second humidity threshold value;

[0122] S05, when the auxiliary fan is turned on, the processor obtains a new humidity value in the drawer assembly, and controls the switch of the circulation fan according to the ratio of the new humidity value in the drawer assembly to the second humidity threshold.

[0123] In the embodiment of the present disclosure, when the main fan is turned off and the auxiliary fan is turned on, the humidity in the drawer assembly is assisted by the auxiliary fan to adjust the humidity in the drawer assembly to reduce the humidity in the drawer assembly. In this way, after the auxiliary fan is turned on, a new humidity value can be obtained for comparison, and the switch of the circulation fan can be controlled according to the result until the circulation fan is turned off, so that the humidity in the drawer assembly meets the demand.

[0124] Combination Fig.23 As shown, the embodiment of the present disclosure provides another control method for a refrigerator, comprising:

[0125] S01, when the first air outlet 101 and the second air outlet 102 are both opened to discharge air, the processor obtains the temperature value in the drawer assembly;

[0126] S02, when the temperature value of the drawer assembly is higher than the shutdown temperature of the refrigerator, the processor obtains the humidity value in the drawer assembly, and controls the switch of the second air outlet 102 according to the ratio of the humidity value of the drawer assembly to the first humidity threshold value;

[0127] S21, controlling the switch of the second air vent 102 includes controlling the second air vent 102 to be closed or maintained open; when the second air vent 102 is controlled to be closed or maintained open, the processor obtains a new temperature value in the drawer assembly, and controls the switch of the second air vent 102 and / or the switch of the main fan again according to the ratio of the new temperature value in the drawer assembly to the shutdown temperature of the refrigerator;

[0128] S03, when the temperature value of the drawer assembly is lower than or equal to the shutdown temperature of the refrigerator, the processor controls the main fan to turn off.

[0129] In the embodiment of the present disclosure, by controlling the second air vent to be closed or maintained open, a new temperature value in the drawer assembly is re-acquired, and the switch of the second air vent and / or the switch of the main fan are controlled again according to the ratio of the new temperature value in the drawer assembly to the shutdown temperature of the refrigerator; this cycle is repeated to keep the humidity and temperature in the drawer assembly within a stable range, thereby avoiding affecting the freezing and preservation effect of the food.

[0130] Optionally, the refrigerator also includes: a humidity sensor 70, which is arranged in the drawer body 20, for detecting the humidity inside the drawer body 20; wherein the humidity sensor 70 is connected to the damper assembly 50 and / or the circulating fan 60 at the second air outlet 102, and the damper assembly 50 and / or the circulating fan 60 triggers an action according to the signal transmitted by the humidity sensor 70, so as to maintain the humidity inside the drawer body 20 within a set range.

[0131] For example, when the humidity sensor 70 detects that the relative humidity value in the drawer has dropped to 82%, a signal is sent to trigger the motor 503 of the damper assembly 50 to operate, so that the damper sliding piece 501 closes the second air port 102, that is, the air flow rate and flow rate of the auxiliary air path are reduced to prevent the humidity in the drawer from continuing to decrease. When the air supply duct stops supplying air, due to the characteristics of the moisture permeable membrane 402 itself, when the relative humidity is higher than 85%, it actively permeates moisture to the outside; when the relative humidity is lower than 80%, it stops permeating moisture to the outside to prevent the humidity in the drawer from decreasing. At this time, through the indirect cooling of the drawer body 20 and the drawer cover 30 and the first ventilation part 100 and the second ventilation part 200 under weak natural convection conditions, the temperature inside and outside the drawer is consistent, thereby achieving precise temperature control inside the drawer. When the humidity sensor 70 detects that the relative humidity is higher than 87%, the circulating fan 60 is started, and the damper assembly 50 is opened, that is, the second air outlet 102 is opened to reduce the relative humidity in the drawer to 82%. The circulating fan 60 is stopped and the second air outlet 102 is closed, thereby ensuring that the food in the drawer is always maintained in a high humidity environment with a relative humidity of 80% to 85%, thereby improving the preservation effect of the food.

[0132] Optionally, the inner tank 10 further includes: a third air outlet 103, located below the second air outlet 102; the third air outlet 103 corresponds to the middle or lower part of the drawer body 20 to quickly cool the drawer. Fig.10 shown.

[0133] The airflow blown out of the third air outlet 103 has the same temperature and humidity as the airflow blown out of the first air outlet 101 and the second air outlet 102. The airflow is blown directly to the middle or lower part of the drawer body 20 through the third air outlet 103, so that the middle and lower parts of the drawer body 20 can be quickly cooled down, thereby quickly cooling the food in the drawer, and avoiding the drawer cover 30 blocking the cold air from blowing directly on the food, which slows down the freezing rate of the food.

[0134] The first air vent 101 and the second air vent 102 provided in this embodiment can be regarded as the upper air vent relative to the drawer body 20, and the third air vent 103 can be regarded as the lower air vent relative to the drawer body 20. Two groups of air vents are arranged longitudinally at the rear of the drawer body 20. The upper air vent is used in conjunction with the perspective assembly to achieve humidity control and frost control (reduce the amount of frost formation) of the drawer, and the lower air vent is used to blow cold air directly to the bottom of the drawer and the side wall other than the top to achieve rapid cooling. On the one hand, the food in the drawer can be cooled more quickly. On the other hand, when a small amount of food is stored or the longitudinal height of the drawer is too large, which is prone to form a longitudinal humidity, the limited water vapor in the drawer can be locked in the form of condensation on the inside of the drawer, avoiding the disadvantageous situation that only the upper air vent exists, resulting in continuous upward movement and rapid loss of moisture, and avoiding the continuous formation of an upper and lower humidity gradient in the drawer body 20, resulting in continuous and rapid loss of moisture.

[0135] Optionally, the air outlet areas of the upper air outlet and the lower air outlet are both adjustable.

[0136] When used under normal moisturizing function, the air outlet area of ​​the upper air outlet is smaller than that of the lower air outlet. The upper air outlet is used to realize humidity control and frost control of the moisturizing drawer, and the lower air outlet has a large area to achieve rapid cooling. On the one hand, it can make the food in the drawer cool down more quickly, and on the other hand, it can lock the water vapor in the drawer in the form of condensation on the inside of the drawer, so that the relative humidity of the air at the bottom is higher and closer to the humidity on the surface of the food, avoiding the continuous migration of moisture in the food. The upper air outlet has a smaller area, a higher relative temperature, and a lower relative humidity. While controlling frost, it minimizes the loss of moisture, avoiding the continuous formation of an upper and lower humidity gradient in the drawer body 20, which leads to continuous and rapid loss of moisture.

[0137] Furthermore, if the upper cover 403 is frosted due to improper use by the user, the area of ​​the upper air vent can be increased to accelerate the top air circulation and eliminate the frosting when the food is stored in the drawer. After the abnormal situation is corrected, the air outlet area of ​​the air vent can be restored to normal. It is not necessary to empty the food in the drawer before defrosting.

[0138] Optionally, the first ventilation portion 100 is configured to be formed by the drawer cover 30, the top of the drawer body 20, or between the drawer cover 30 and the drawer body 20. Figure 3 shown.

[0139] When the first ventilation portion 100 is configured on the top of the drawer cover 30 or the drawer body 20, the first ventilation portion 100 can be a plurality of ventilation holes, or a ventilation slot arranged through. When the first ventilation portion 100 is configured between the drawer cover 30 and the drawer body 20, the first ventilation portion 100 can be a gap, a flash gap, etc. formed between the drawer cover 30 and the drawer body 20.

[0140] Optionally, the second ventilation portion 200 is configured to be formed by the drawer cover 30, the top of the drawer body 20, or between the drawer cover 30 and the drawer body 20. Figure 3 shown.

[0141] When the second ventilation portion 200 is configured on the top of the drawer cover 30 or the drawer body 20, the second ventilation portion 200 can be a plurality of ventilation holes, or a ventilation slot arranged through. When the second ventilation portion 200 is configured between the drawer cover 30 and the drawer body 20, the second ventilation portion 200 can be a gap, a flash gap, etc. formed between the drawer cover 30 and the drawer body 20.

[0142] It should be noted that the specific positions of the first ventilation part 100 and the second ventilation part 200 can be determined according to actual conditions, and are not limited to the same component (i.e., the top of the drawer cover 30 or the drawer body 20), and are both formed between the drawer cover 30 and the drawer body 20.

[0143] Combination Figures 14 to 19 As shown. Optionally, the moisture permeable component 40 includes a lower seat 401 and a moisture permeable membrane 402. The lower seat 401 is configured with a first hollow portion 4011 for covering the top of the drawer; the moisture permeable membrane 402 is disposed above the lower seat 401; wherein the inner side wall of the first hollow portion 4011 is configured with an upwardly inclined water vapor guide surface 4012 and a downwardly inclined condensation water guide surface 4013, and the condensation water guide surface 4013 is located above the water vapor guide surface 4012 and is disposed to intersect. In this way, the moisture permeable component 40 is located at the top of the drawer, and the water vapor in the drawer passes through the first hollow portion 4011 of the lower seat 401 and moves toward the moisture permeable membrane 402, and the purpose of moisture permeation and humidity adjustment is achieved through the moisture permeable membrane 402; through the water vapor guide surface 4012 and the condensation water guide surface 4013 of the first hollow portion 4011, not only the fluidity of water vapor can be increased, but also the condensation water condensed on the inner side of the moisture permeable membrane 402 can be guided, thereby preventing water vapor and condensation water from freezing on the lower seat 401 and the inner side of the moisture permeable membrane 402, and the amount of frost can be effectively reduced.

[0144] Optionally, the moisture permeable component 40 includes a moisture permeable membrane 402, which has a three-layer structure, namely a hydrophobic layer, a water-conducting layer and a hydrophilic layer. Among them, the moisture permeable aperture of the moisture permeable membrane 402 is above a certain humidity threshold and can be adjusted automatically according to the size of the humidity value. When the main fan stops supplying air, due to the characteristics of the moisture permeable membrane 402 itself, when the relative humidity is higher than 85%, it actively permeates moisture to the outside; when the relative humidity is lower than 80%, it stops permeating moisture to the outside to prevent the humidity of the food from decreasing. At this time, through the indirect cooling of the drawer body 20 and the drawer cover 30 and the first ventilation part 100 and the second ventilation part 200 formed under weak natural convection conditions, the temperature inside and outside the drawer is consistent, thereby achieving precise temperature control inside the drawer. In actual application, since the temperature of the freezing chamber is controlled by a temperature sensor, when the temperature is lower than -20°C, the compressor stops refrigeration. When the temperature rises to -15°C, the moisture lost by the food itself and the effect of the moisture permeable membrane 402 will increase the relative humidity in the drawer to about 85%; when the temperature reaches -15°C, the compressor starts refrigeration, and when the temperature drops to -20°C, the humidity in the drawer is reduced, which will reduce the relative humidity in the drawer to about 80%, thereby ensuring that the food in the drawer is always maintained in a high humidity environment with a relative humidity of 80% to 85%, thereby improving the preservation effect of the food.

[0145] Exemplarily, the moisture permeable membrane 402 has a three-layer structure. When the relative humidity is above 80%, the surface facing the inner side of the drawer is hydrophobic, the middle layer (ie, the layer having the nano-microporous structure) is water-conductive, and the layer facing away from the inner side of the drawer is hydrophilic.

[0146] In order to protect the moisture permeable film 402, non-woven fabrics can be added on both sides of the film, and plastic sealing can be performed around the film to ensure that the moisture permeable film 402 is protected from external violent damage.

[0147] When the lower seat 401 is placed horizontally, the inner side wall of the first hollow portion 4011 protrudes outward and the cross section is triangular or similar to a triangular shape. It can be understood that the condensed water guide surface 4013 and the water vapor guide surface 4012 are two intersecting planes protruding outward from the inner side wall of the first hollow portion 4011. The condensed water guide surface 4013 is located above the water vapor guide surface 4012.

[0148] When the drawer cover 30 with the moisture permeable component 40 is covered on the drawer body 20, the water vapor in the drawer body 20 flows upward along the water vapor guide surface 4012. During the flow, water droplets carried in the water vapor condense into condensed water after contacting the water vapor guide surface 4012, and then slide downward along the inclined water vapor guide surface 4012 and drip into the drawer body 20. This not only reduces the discharge of water vapor in the drawer, but also prevents the water vapor from frosting on the side wall of the first hollow part 4011, thereby causing blockage and affecting the flow of water vapor.

[0149] Since the drawer cover 30 plays the role of indirectly cooling the food in the drawer, the air outside the drawer is lower than the temperature inside the drawer. Therefore, when the water vapor in the drawer is higher than the set humidity and is dissipated through the moisture permeable component 40, the water vapor in contact with the lower cover will condense, that is, the water vapor condenses on the condensation water guide surface 4013 of the first hollow part 4011 to form condensed water. Based on the inclined setting of the condensation water guide surface 4013, the condensed water flows downward along the inclined surface, thereby avoiding condensation and freezing on the condensation water guide surface 4013. In addition, the condensation water guide surface 4013 faces the moisture permeable membrane 402, which can not only make the water vapor flow along the condensation water guide surface 4013 to guide the condensed condensed water, but also increase the contact area between the water vapor on the first hollow part 4011 and the moisture permeable membrane 402.

[0150] Optionally, a water stop step 4014 is constructed at the intersection of the water vapor guide surface 4012 and the condensate guide surface 4013, and the water stop step 4014 is used to stop the water droplets carried by the water vapor that moves along the water vapor guide surface 4012 to the water stop step 4014 from continuing to move upward; wherein, the two ends of the water stop step 4014 are respectively connected to the top of the water vapor guide surface 4012 and the bottom of the condensate guide surface 4013.

[0151] The water stop step 4014 is located at the intersection of the water vapor guide surface 4012 and the condensed water guide surface 4013, and the bottom of the condensed water guide surface 4013 protrudes from the top of the water vapor guide surface 4012. When the water vapor in the drawer moves upward along the water vapor guide surface 4012 to the water stop step 4014, some water droplets carried in the water vapor adhere to the water vapor guide surface 4012, and under the guidance of the inclined setting of the water vapor guide surface 4012, the water droplets attached to the water vapor guide surface 4012 move downward to drip. The water droplets carried in another part of the water vapor move to the water stop step 4014, and under the stopping effect of the water stop step 4014, they adhere to the surface of the water stop step 4014, and then drip into the drawer. It should be noted that the water stop step 4014 can not only be used to stop the water droplets in the water vapor, but also play a certain role in hindering the upward movement of the water vapor, which can further extend the time that the water vapor is in the drawer. In addition, the water droplets in the water vapor include not only the water droplets originally carried, but also the water droplets formed by condensation of water vapor during the movement.

[0152] The water-stopping step 4014 can prevent water droplets in the water vapor from moving to the lower side of the moisture-permeable membrane 402, thereby reducing the amount of frost on the lower side of the moisture-permeable membrane 402 and the lower cover, and preventing the moisture-permeable membrane 402 and the first hollow portion 4011 of the lower cover from being blocked, thereby ensuring the moisture-permeable effect of the moisture-permeable component 40.

[0153] Optionally, the water stop step 4014 is arranged parallel to the upper surface of the lower seat 401. In this way, the water vapor and the water droplets carried in the water vapor can be better stopped.

[0154] Optionally, the angle between the condensation water guide surface and the vertical plane is greater than or equal to 7°, so that the condensation water condensed between the moisture permeable membrane 402 and the lower seat 401 flows downward along the condensation water guide surface to avoid condensation.

[0155] In this embodiment, the moisture permeable component 40 is arranged horizontally when in use. Thus, when the angle between the condensation water guide surface and the vertical plane is 7°, it is the minimum angle at which water vapor and condensation water can flow downward along the condensation water guide surface 4013, so that water vapor and condensation water can be prevented from condensing and frosting on the condensation water guide surface 4013, thereby reducing the amount of frost on the inner side of the moisture permeable membrane 402, avoiding blockage of the moisture permeable membrane 402 and the first hollow portion 4011 of the lower cover, and thus ensuring the moisture permeability effect of the moisture permeable component 40.

[0156] When the angle between the condensation water guide surface and the vertical plane is greater than 7°, water vapor and condensation water can flow downward along the condensation water guide surface 4013, avoiding frost on the inner side of the moisture permeable membrane 402 and the upper surface of the lower cover, thereby avoiding blockage of the moisture permeable membrane 402 and the first hollow portion 4011 of the lower cover, thereby ensuring the moisture permeability effect of the moisture permeable component 40.

[0157] Optionally, the angle between the water vapor guide surface 4012 and the vertical plane is less than or equal to 2° to prevent the water vapor from condensing on the water vapor guide surface 4012 when flowing along the water vapor guide surface 4012 .

[0158] In this embodiment, the moisture permeable component 40 is arranged horizontally when in use. Thus, when the angle between the water vapor guide surface 4012 and the vertical plane is 2°, the water vapor guide surface 4012 can not only play a guiding role, but also prevent water vapor from condensing on the guide surface, thereby eliminating the risk of water vapor freezing and frosting on the water vapor guide surface 4012.

[0159] When the angle between the water vapor guide surface 4012 and the vertical plane is less than 2°, it can be ensured that the water vapor cannot condense on the guide surface, thereby eliminating the risk of water vapor freezing or frosting on the water vapor guide surface 4012 .

[0160] Optionally, the moisture permeable component 40 also includes an upper cover 403, which is constructed with multiple second hollow portions 4031, and the upper cover 403 is detachably connected to the lower seat 401; wherein the lower surface of the upper cover 403 and the upper surface of the lower seat 401 enclose a moisture permeable cavity, and the moisture permeable membrane 402 is arranged in the moisture permeable cavity.

[0161] The moisture permeable component 40 is connected to the lower seat 401 through the upper cover 403, and the moisture permeable membrane 402 is confined in the moisture permeable cavity, which can not only further fix the position of the moisture permeable membrane 402, but also protect the moisture permeable membrane 402 to prevent the moisture permeable membrane 402 from being damaged, thereby affecting the moisture permeability effect.

[0162] In addition, the moisture permeable assembly 40 is horizontally arranged when in use, the lower seat 401 is located below the moisture permeable membrane 402, and the upper cover 403 is located above the moisture permeable membrane 402. The plurality of second hollow portions 4031 constructed by the upper cover 403 facilitate the water vapor transmitted from the moisture permeable membrane 402 to be discharged through the second hollow portions 4031, that is, the second hollow portions 4031 serve the purpose of discharging water vapor.

[0163] Optionally, the second hollow portion 4031 is arranged corresponding to the first hollow portion 4011 , so that the water vapor penetrating from the first hollow portion 4011 passes through the moisture-permeable membrane 402 and is discharged from the second hollow portion 4031 .

[0164] Optionally, the side wall of the second hollow portion 4031 is also configured with a water vapor guide surface 4012, a condensed water guide surface 4013 and a water stop step 4014. In this way, it can help reduce the frost of the permeated water vapor on the second hollow portion 4031 and the upper side of the moisture permeable membrane 402, and avoid clogging the second hollow portion 4031 and the moisture permeable membrane 402.

[0165] Optionally, the edge of the upper surface of the lower seat 401 protrudes upward to form a boss 4015; when the lower seat 401 is connected to the upper cover 403, the boss 4015 abuts against the moisture-permeable membrane 402 to press the moisture-permeable membrane 402 against the lower surface of the upper cover 403.

[0166] In this embodiment, the edge of the upper surface of the lower seat 401 protrudes upward to form a boss 4015, that is, when the moisture permeable membrane 402 is arranged in the moisture permeable cavity, the edge of the moisture permeable membrane 402 overlaps the boss 4015. When the lower seat 401 is connected to the upper cover 403, the boss 4015 presses the moisture permeable membrane 402 against the lower surface of the upper cover 403, so that the moisture permeable membrane 402 is pressed against the lower surface of the upper cover 403, and the moisture permeable membrane 402 is reinforced to prevent the moisture permeable membrane 402 from moving in the moisture permeable cavity.

[0167] Optionally, the boss 4015 may be arranged around the circumference of the lower seat 401. In this way, the edges of the moisture permeable membrane 402 are all pressed against the lower surface of the upper cover 403. In this way, not only the stability of the moisture permeable membrane 402 can be ensured, but also the flatness of the moisture permeable membrane 402 can be ensured, and wrinkles in the moisture permeable membrane 402 are prevented to affect the moisture permeability effect.

[0168] Optionally, the lower seat 401 is configured with an elastic claw 4016 , and the upper cover 403 is configured with a limiting groove 4033 , and the elastic claw 4016 is engaged with the limiting groove 4033 , so that the lower seat 401 and the upper cover 403 are detachably connected.

[0169] Combination Fig.14 and Fig.17 As shown, the lower seat 401 provided in one embodiment has a curved elastic claw 4016, and a portion of the lower surface edge of the upper cover 403 extends downward to form a limit plate 4032, and the limit plate 4032 forms a limit groove 4033. The lower seat 401 is assembled with the upper cover 403 from bottom to top, and the limit plate 4032 is located at the outer edge of the lower seat 401. When the elastic claw 4016 of the lower seat 401 moves upward from the edge of the limit plate 4032, the elastic claw 4016 is compressed and deformed until the limit end of the elastic claw 4016 moves into the limit groove 4033. In this way, the elastic claw 4016 is clamped in the limit groove 4033 of the upper cover 403, and the clamping and fixing of the lower seat 401 and the upper cover 403 is achieved. When the lower seat 401 and the upper cover 403 need to be disassembled, the limiting end of the elastic claw 4016 only needs to be pressed inward to make it escape from the limiting groove 4033 , and then the lower seat 401 and the upper cover 403 can be separated.

[0170] Optionally, the lower seat 401 is configured with a card slot, and the upper cover 403 is configured with a card connection portion 4034, and the card connection portion 4034 is inserted into the card slot so that the upper cover 403 and the lower seat 401 are detachably connected.

[0171] Combination Fig.18 and Fig.19 As shown, another embodiment provides a lower seat 401 with a slot, and an upper cover 403 with a snap-on portion 4034. When the upper cover 403 is connected to the lower cover, the snap-on portion 4034 of the upper cover 403 is directly inserted into the slot of the lower seat 401 to achieve snap-on fixation. Optionally, the snap-on portion 4034 is provided on the lower surface of the upper cover 403 and is provided perpendicular to the upper cover 403.

[0172] Optionally, the clamping portion 4034 includes a guiding and protecting portion 4035 and two elastic portions, and the two elastic portions are located on both sides of the guiding and protecting portion 4035. When the clamping portion 4034 is inserted into the card slot, the guiding and protecting portion 4035 is used to guide the two elastic portions, so that the clamping portion 4034 is clamped in the card slot to avoid falling out.

[0173] Optionally, the elastic portion includes a columnar elastic deformation portion 4036 and an elastic force recovery portion 4037 connecting the elastic deformation portion 4036 and the guide protection portion 4035, wherein the elastic deformation portion 4036 and the guide protection portion 4035 are both arranged perpendicular to the upper cover 403 and are arranged at a certain distance from each other, and the elastic force recovery portion 4037 is bent and is located between the elastic deformation portion 4036 and the guide protection portion 4035.

[0174] The guiding protection part 4035 can avoid the defect of unclear guidance of the upper cover 403 and the lower seat 401 during the installation process, and can also play a protective role after installation. The elastic force recovery part 4037 is added to ensure that the elastic deformation part recovers sufficient elastic force after installation to reach the state before elastic deformation, thereby satisfying the fixed connection between the upper cover 403 and the lower seat 401 and preventing loosening.
