[0059] Figure 1 FIG. 1 is a flow chart of a method for controlling a refrigerator according to an embodiment of the present invention. Figure 1 As shown, and refer to Figures 2 to 11 The embodiment of the present invention provides a control method for a refrigerator 100. The refrigerator 100 includes a storage compartment, a humidity control drawer 110 disposed in the storage compartment, and a dehumidification fan 130. A moisture permeable membrane 120 is disposed on the humidity control drawer 110. The dehumidification fan 130 causes airflow to flow through the outer surface of the moisture permeable membrane 120.

[0060] Control methods include:

[0061] Step S111, obtaining the switch status of the door of the storage compartment and the switch status of the humidity control drawer 110;

[0062] Step S112, controlling the operation of the dehumidification fan 130 according to the switch state of the storage compartment door and the switch state of the humidity control drawer 110.

[0063] like Figure 2 As shown, in some other embodiments of the present invention, the control method includes:

[0064] Step S121, obtaining the operating status of the refrigerator 100;

[0065] Step S122, controlling the operation of the dehumidification fan 130 according to the operating state of the refrigerator 100.

[0066] like Figure 3 As shown, in some further embodiments of the present invention, the control method includes:

[0067] Step S131, obtaining the humidity of the humidity control drawer 110;

[0068] Step S132 , controlling the operation of the dehumidification fan 130 according to the humidity of the humidity control drawer 110 .

[0069] In these embodiments, the specific working process includes: obtaining the switch state of the door of the storage compartment and the switch state of the humidity control drawer 110, and controlling the operation of the dehumidification fan 130 according to the switch state of the door of the storage compartment and the switch state of the humidity control drawer 110; or obtaining the operation state of the refrigerator 100, and controlling the operation of the dehumidification fan 130 according to the operation state of the refrigerator 100. Or obtaining the humidity of the humidity control drawer 110, and controlling the operation of the dehumidification fan 130 according to the humidity of the humidity control drawer 110. The moisture permeable film has a hydrophilic group and conducts moisture through moisture absorption, thereby having a moisture permeable function. The moisture permeable film 120 is arranged on the control drawer so that the moisture in the humidity control drawer 110 is transferred from the inside of the humidity control drawer 110 to the outside of the humidity control drawer 110. When the dehumidification fan 130 is working, the airflow speed on the outer surface of the moisture permeable membrane 120 is accelerated, and the airflow takes away the moisture on the outer side of the moisture permeable membrane 120, forming a humidity difference between the inside and outside of the moisture permeable membrane 120, accelerating the rate at which moisture passes through the moisture permeable membrane 120, and improving the dehumidification effect. When the dehumidification fan 130 stops working, the humidity of the humidity control drawer 110 is maintained within a certain range. In this working process, the humidity inside the humidity control drawer 110 is adjusted by controlling the opening and closing of the dehumidification fan 130.

[0070] In this embodiment, the dehumidification fan 130 is provided to accelerate the speed at which the moisture in the humidity control drawer 110 flows out through the moisture permeable membrane 120, thereby improving the humidity adjustment efficiency. The humidity of the humidity control drawer 110 is adjusted according to the switch state of the door of the storage compartment, the switch state of the humidity control drawer 110, the operating state of the refrigerator 100 and / or the humidity of the humidity control drawer 110, so as to solve the problem of passive humidity adjustment of the humidity control drawer 110, avoid condensation or low humidity in the storage compartment, and achieve the purpose of actively controlling the humidity of the humidity control drawer 110, thereby ensuring the storage effect of the food in the humidity control drawer 110.

[0071] like Figure 4As shown, in some embodiments of the present invention, the operation of the dehumidification fan 130 is controlled according to the switch state of the storage compartment door, the switch state of the humidity control drawer 110, or the operating state of the refrigerator 100 and / or the humidity of the humidity control drawer 110, including:

[0072] Step S211, when the door of the storage compartment is closed, start the dehumidification fan 130;

[0073] Step S212, when the storage compartment starts the cooling mode, turn off the dehumidification fan 130;

[0074] Step S213, after the storage compartment turns off the cooling mode for a first preset time, the dehumidification fan 130 is turned on;

[0075] Step S214, after the second preset time period, turn off the dehumidification fan 130.

[0076] In this embodiment, when the door of the storage compartment is closed, the dehumidification fan 130 is started to prevent condensation caused by excessive humidity inside the humidity control drawer 110. When the storage compartment starts the cooling mode, the dehumidification fan 130 is turned off to prevent the dehumidification fan 130 from causing the humidity inside the humidity control drawer 110 to be too low during the cooling process. In addition, the disturbance of the flow of the airflow inside the refrigerator caused by the operation of the dehumidification fan is avoided, and the cooling effect is prevented from being affected by the operation of the dehumidification fan, and energy saving effect can be achieved.

[0077] In some embodiments of the present invention, starting the dehumidification fan 130 when the door of the storage compartment is closed includes: starting the dehumidification fan 130 after the humidity control drawer 110 is opened and closed and when the door of the storage compartment is closed.

[0078] Specifically, the door of the storage room is opened and the humidity control drawer 110 is opened, and the outside air outside the storage room enters the humidity control drawer 110. Compared with the low temperature environment of the humidity control drawer 110, the temperature of the outside air is higher than the air inside the humidity control drawer 110. The saturated vapor pressure of water is positively correlated with temperature, that is, the higher the temperature, the higher the saturated vapor pressure of water, and the lower the temperature, the lower the saturated vapor pressure of water. Therefore, after the high-temperature air from the outside enters the low-temperature humidity control drawer 110, there is a possibility of precipitation of moisture and condensation due to the decrease in temperature. When the humidity control drawer 110 is closed and the door of the storage room is closed, the dehumidification fan 130 is started so that the moisture in the humidity control drawer 110 flows out of the humidity control drawer 110 through the moisture permeable membrane 120 to avoid the generation of condensation.

[0079] In this embodiment, after the humidity control drawer 110 is opened and closed, and the door of the storage compartment is closed, the dehumidification fan 130 is immediately started. The dehumidification fan 130 is started in time to accelerate the airflow near the moisture permeable membrane 120, increase the humidity difference between the inside and outside of the moisture permeable membrane 120, and promote the airflow inside the humidity control drawer 110 to flow out, thereby avoiding condensation and improving the active controllability of humidity control.

[0080] In other embodiments of the present invention, when the door of the storage compartment is closed, starting the dehumidification fan 130 further includes: after the door of the storage compartment is opened for a third preset time, when the door of the storage compartment is closed, starting the dehumidification fan 130. The third preset time can be any value, such as 10s, 20s, 30s, ..., preferably 60s.

[0081] The ability to prolong the storage time of fruits and vegetables in the refrigerator 100 depends, to a certain extent, on the fact that the storage compartment of the refrigerator 100 has a relatively low temperature, which can inhibit the respiration of the fruits and vegetables.

[0082] Specifically, after the door of the storage room is opened for the third preset time, the door of the storage room is closed again. During the time when the door of the storage room is open, regardless of whether the humidity control drawer 110 is opened, its internal temperature will exchange heat with the outside world, so that the temperature inside the humidity control drawer 110 rises, resulting in enhanced respiration of the stored items in the humidity control drawer 110. With enhanced respiration, the moisture inside the humidity control drawer 110 increases, thereby increasing the humidity inside the humidity control drawer 110. Regardless of whether the moisturizing drawer is opened during the period when the door of the storage room is opened, when the door of the storage room is closed again, the dehumidification fan 130 is immediately started to adjust the humidity of the humidity control drawer 110, in order to reduce the humidity inside the humidity control drawer 110.

[0083] In this embodiment, the dehumidification fan 130 is immediately started when the door of the storage compartment is closed again, so as to avoid adjustment after condensation occurs, thereby improving the initiative of humidity adjustment.

[0084] like Figure 5 As shown, in some embodiments of the present invention, the operation of the dehumidification fan 130 is controlled according to the switch state of the storage compartment door, the switch state of the humidity control drawer 110, or the operating state of the refrigerator 100 and / or the humidity of the humidity control drawer 110, including:

[0085] Step S221, after defrosting the evaporator corresponding to the storage compartment, start the dehumidification fan 130;

[0086] Step S222, when the storage compartment starts the cooling mode, turn off the dehumidification fan 130;

[0087] Step S223, after the storage compartment refrigeration ends for the first preset time, the dehumidification fan 130 is turned on and runs for a second preset time.

[0088] Literature indicates that during the defrosting period of the refrigerator 100, the liquid dew condensed on the evaporator surface or the solid frost layer condensed on the evaporator surface will evaporate faster, resulting in an increase in the air humidity of the refrigerating chamber. Accordingly, the humidity inside the humidity control drawer 110 will also increase.

[0089] Specifically, after the defrosting process of the evaporator is completed, the dehumidification fan 130 is started until the storage compartment starts the cooling mode. When the cooling mode is started in the storage compartment, the dehumidification fan 130 is turned off. The dehumidification fan 130 is started after the first preset time period of cooling in the storage compartment is completed, and the dehumidification fan 130 is turned off after running for the second preset time period. The first preset time period and the second preset time period may be equal or unequal. Both the first preset time period and the second preset time period may be any value, such as 30s, 3min, 5min, 10min, 15min..., and is preferably 10min according to the measurement results.

[0090] In this embodiment, when the storage compartment starts the cooling mode, cold air with lower temperature and humidity blows through the surface of the moisture permeable membrane 120, forming a large humidity difference between the inside and outside of the moisture permeable membrane 120, thereby discharging excess water vapor in the humidity control drawer 110 through the moisture permeable membrane 120 out of the humidity control drawer 110. At this time, if the dehumidification fan 130 is turned on at the same time, it will cause excessive moisture in the humidity control drawer 110 to be taken away through the moisture permeable membrane 120, and the humidity inside the humidity control drawer 110 will be too low, affecting the storage effect. After the cooling is completed, the dehumidification fan 130 starts to run for the first preset time to avoid the dehumidification fan 130 running directly, which will cause the humidity control drawer 110 to have too much moisture permeability and low humidity.

[0091] like Figure 6 As shown, in some embodiments of the present invention, the operation of the dehumidification fan 130 is controlled according to the switch state of the storage compartment door, the switch state of the humidity control drawer 110, or the operating state of the refrigerator 100 and / or the humidity of the humidity control drawer 110, including:

[0092] Step S231, calculating the humidity rising rate of the humidity control drawer 110 according to the humidity of the humidity control drawer 110;

[0093] Step S232 , controlling the operation of the dehumidification fan 130 according to the humidity rising rate of the humidity control drawer 110 .

[0094] In this embodiment, the humidity rise of the humidity control drawer 110 is calculated according to the humidity of the humidity control drawer 110 obtained. The operation of the dehumidification fan 130 is controlled according to the humidity rise rate of the humidity control drawer 110. In this embodiment, the operation of the dehumidification fan 130 is controlled by the humidity rise rate, and the change trend of the humidity in the humidity control drawer 110 is taken into account, which strengthens the advance prediction and improves the initiative of the control.

[0095] like Figure 7 As shown, in other embodiments of the present invention, the operation of the dehumidification fan 130 is controlled according to the switch state of the storage compartment door, the switch state of the humidity control drawer 110, or the operating state of the refrigerator 100 and / or the humidity of the humidity control drawer 110, including:

[0096] Step S241, calculating the humidity rising rate of the humidity control drawer 110 according to the humidity of the humidity control drawer 110;

[0097] Step S242, controlling the operation of the dehumidification fan 130 according to the humidity of the humidity control drawer 110 and the humidity rising rate.

[0098] In this embodiment, the humidity rise of the humidity control drawer 110 is calculated according to the humidity of the humidity control drawer 110 obtained. The operation of the dehumidification fan 130 is controlled according to the humidity and the humidity rise rate of the humidity control drawer 110. In this embodiment, the operation of the dehumidification fan 130 is controlled by the humidity and the humidity rise rate, and the humidity value and the humidity change trend in the humidity control drawer 110 are comprehensively considered, and the factors considered are more comprehensive.

[0099] Of course, in some other embodiments of the present invention, the operation of the dehumidification fan 130 may be controlled according to the switch state of the storage compartment door, the switch state of the humidity control drawer 110, the operating state of the refrigerator 100 and / or the humidity of the humidity control drawer 110, or the operation of the dehumidification fan 130 may be controlled only according to the humidity of the humidity control drawer 110.

[0100] In this embodiment, the operation of the dehumidification fan 130 is controlled according to the humidity of the humidity control drawer 110. In this embodiment, the operation of the dehumidification fan 130 is controlled only by the humidity of the humidity control drawer 110, and the humidity of the humidity control drawer 110 is easy to detect and easy to operate.

[0101] The humidity rise rate is the change value of humidity per unit time. The defined unit time can be 10s, 20s, 30s, etc., or 1min, 3min, 5min, etc. For the convenience of calculation, the unit time is preferably 10min. The humidity change value can be the difference of relative humidity per unit time, or the difference of absolute humidity per unit time. For the convenience of calculation, the difference of relative humidity is preferred.

[0102] like Figure 8 As shown, in some embodiments of the present invention, the operation of the dehumidification fan 130 is controlled according to the humidity and / or humidity rising rate of the humidity control drawer 110, including:

[0103] Step S251, when the humidity of the humidity control drawer 110 is greater than a first preset humidity value, and the humidity rising rate is greater than the first preset value, the dehumidification fan 130 is operated at a first speed;

[0104] Step S252, when the humidity of the humidity control drawer 110 is less than or equal to the first preset humidity value, or the humidity rising rate is less than or equal to the first preset value, the dehumidification fan 130 is operated at a second speed;

[0105] The first rotation speed is greater than the second rotation speed.

[0106] In this embodiment, the humidity of the humidity control drawer 110 is less than or equal to the first preset humidity value, or the humidity rising rate is less than or equal to the first preset value, including the following three situations: the humidity of the humidity control drawer 110 is less than or equal to the first preset humidity value, and the humidity rising rate is greater than the first preset value; the humidity of the humidity control drawer 110 is greater than the first preset humidity value, and the humidity rising rate is less than or equal to the first preset value; the humidity of the humidity control drawer 110 is less than or equal to the first preset humidity value, and the humidity rising rate is less than or equal to the first preset value. Depending on the items stored in the humidity control drawer 110, the first preset humidity value can take different ranges or values, generally 90-95%, preferably 95%. The first preset value can be any value, preferably 10% / 10min.

[0107] In this embodiment, it is determined that the humidity control drawer 110 is under different humidity and / or different humidity rising rates, and the dehumidification fan 130 operates at different speeds. When the humidity is high and the humidity rising rate is large, the dehumidification fan 130 operates at a higher speed to accelerate the airflow on the surface of the moisture permeable membrane 120, and promote the moisture in the humidity control drawer 110 to flow out through the moisture permeable membrane 120, thereby accelerating the reduction of the humidity in the humidity control drawer 110. Vice versa. The dehumidification fan 130 can operate at different speeds to better match the actual humidity value and / or humidity rising rate inside the humidity control drawer 110, so as to make the control more precise.

[0108] In some embodiments of the present invention, the dehumidification mode operation of the humidity control drawer 110 is controlled according to the humidity of the humidity control drawer 110 and the humidity rise rate, including: when the humidity of the humidity control drawer 110 is less than a second preset humidity value, the dehumidification fan 130 is turned off.

[0109] In this embodiment, when the humidity in the humidity control drawer 110 is less than the second preset humidity value, the dehumidification fan 130 is turned off to prevent the humidity inside the humidity control drawer 110 from being too low, causing a large amount of moisture loss from the stored items. The second preset humidity value can take different ranges or values, generally 85%-90%, preferably 85%.

[0110] In some embodiments of the present invention, the obtaining of the switch state of the humidity control drawer 110 includes: obtaining the switch state of the humidity control drawer 110 by the user through at least one of a magnetic induction switch and a photoelectric sensor.
