[0068] See Figure 1 , is a schematic structural diagram of a refrigerator provided under one embodiment of the present invention.

[0069] Embodiments of the present invention provides a refrigerator, comprising:

[0070] Cabinet;

[0071] Drawer 1, located in the box body;

[0072] Fan 2, for inducing the flow of air within the drawer 1;

[0073] The first detection device 3 for detecting the internal temperature and internal humidity of the drawer 1;

[0074] A second detection device 4 for detecting the temperature of the inner wall of the drawer 1;

[0075] Controller 5, which is configured to:

[0076] S11, determine whether the refrigerator has reached a stable state, if so, then perform the next step S12;

[0077] S12, N consecutive times by the first detection device 3 and the second detection device 4 to detect the internal temperature of the drawer 1, internal humidity and inner wall temperature; wherein the N≥2;

[0078] S13, if it is judged that the inner wall temperature detected each time is less than the condensation temperature corresponding to the internal temperature and internal humidity detected at that time, the refrigerator is controlled to enter the drawer anti-condensation mode;

[0079] Wherein, the drawer anti-condensation mode comprising: controlling the fan 2 starts.

[0080] It will be appreciated that the refrigerator comprises a refrigeration system. Exemplary, the refrigeration system comprises a compressor, a refrigeration fan, an evaporator, a filter, a capillary, a condensing tube and other components, in the operation of the compressor, the refrigerant gas is compressed by the compressor to a high temperature and high pressure of superheating evaporation, and through the compressor exhaust pipe into the condensing tube, the superheated vapor is condensed in the condensing tube into a high temperature medium pressure liquid, high temperature medium pressure refrigerant liquid through the filter filter into the capillary, after the capillary throttling and pressure reduction from high temperature medium pressure to low temperature low pressure, The low-temperature and low-pressure refrigerant liquid absorbs a large amount of external heat in the evaporator and vaporizes into saturated vapor to achieve refrigeration, and then inhales it as low-pressure steam, and then is sucked in by the compressor to maintain circulation. The box body is provided with a number of refrigeration chambers, for example, a refrigeration chamber, a freezer room, a vacuum preservation room, etc., drawer 1 is provided in the refrigeration room room, each room is equipped with a temperature detection device, after the refrigerator is powered on, the compressor and the refrigeration fan of each room are operated continuously according to the normal set speed, it can be judged by the following way whether the refrigerator has reached a stable state: Detect whether the temperature of several of the refrigeration chambers has reached the corresponding shutdown point of several refrigeration chambers, if yes, Then determine that the refrigerator has reached a steady state.

[0081] Exemplarily, the air supply port 11 of the drawer 11 is disposed on the top of the drawer 1, such as Figure 2 As shown, in this case, the wall temperature of drawer 1 in the refrigeration process of drawer 1 is lower, when the wall temperature is lower than the dew point temperature at this time, it will cause water vapor to produce bead-like condensation on the inner wall of vacuum drawer 1, because the water vapor density is lower than the air and the top of drawer 1 is supplied, the top temperature of drawer 1 is lower than other positions, and usually water droplets appear on the top inner wall of drawer 1, such as Figure 3 as shown. Then the fan 2, the first detection device 3 and the second detection device 4 may be located on the top of the drawer 1, as Figure 4 shown, thus guaranteeing an anti-condensation effect. as Figure 5 As shown, the fan 2, the first detection device 3 and the second detection device 4 may be integrated into one, in order to facilitate disassembly. as Figure 4 and 6 As shown, the air inlet 21 of the fan 2 may be perpendicular to the top of the drawer 1, the air outlet 22 of the fan 2 may be parallel to the top of the drawer 1, so that the air circulation path within the drawer 1 is as follows Figure 7 As shown, it is ensured that the wind can blow to the top of drawer 1, prevent condensation on the top, and allow the air in drawer 1 to circulate fully.

[0082] It should be noted that, in the step S12, the number of consecutive detections N and the interval between each two detections may be set according to the actual needs, not limited herein. In the present embodiment, the false positive rate caused by multiple detections to reduce the sensor measurement error. Condensation temperature refers to the temperature at which moisture in the air condenses into water droplets, and when the temperature of the inner wall of drawer 1 is lower than the condensation temperature, condensation will form on the inner wall. And because of the different internal temperature and internal humidity, will have an impact on the condensation temperature, if the use of a fixed condensation temperature, can not accurately reflect the risk of condensation, therefore, in the step S13, for each detection in N times, by obtaining the internal temperature obtained by the detection and the condensation temperature corresponding to the condensation temperature, and then the detection of the inner wall temperature and the condensation temperature comparison, can accurately determine whether there is a risk of condensation. Exemplarily, it may be pre-determined different internal temperature Tk and internal humidity RH corresponding to the condensation temperature Tc, and form a corresponding relationship, so that, in step S13, for each detection in N times, by this correspondence, the internal temperature Tk and the internal humidity RH corresponding to the condensation temperature Tc detected can be determined. In a specific embodiment, the correspondence is shown in Table 1.

[0084]

[0085] Preferably, the interval between each two detections is 1 minute, and N equals 5. Then, the step S12 is specifically: every 1 minute to control the first detection device 3 detects the internal temperature and internal humidity of the drawer 1 times and controls the second detection device 4 detects the inner wall temperature of the drawer 1 times, after continuous detection 5 times, the internal temperature detected for 5 consecutive times is T 1 、T 2 、T 3 、T 4 、T 5 , record the internal humidity detected for 5 consecutive times as RH 1 、RH 2 、RH 3 、RH 4 、RH 5 , record the temperature of the inner wall detected 5 times in a row as Tn 1 、Tn 2 、Tn 3 、Tn 4 、Tn 5 。 The step S13 is specifically: according to the internal temperature and internal humidity detected for 5 consecutive times, according to Table 1 to determine the condensation temperature corresponding to each detection of the internal temperature and internal humidity Tc 1 、Tc 2 、Tc 3 、Tc 4 、Tc 5 , determine whether the temperature of the inner wall detected for 5 consecutive times satisfies Tn 1 ＜Tc 1 、Tn 2 ＜Tc 2 、Tn 3 ＜Tc 3 、Tn 4 ＜Tc 4 、Tn 5 ＜Tc 5 If so, control the refrigerator into drawer anti-condensation mode.

[0090] Determine whether the internal pressure of the drawer 1 is greater than the first preset pressure threshold;

[0091] If so, the control of the vacuum pump starts running until the internal pressure of the drawer 1 is detected by the pressure detection device is less than the second preset pressure threshold, the control of the vacuum pump stops running;

[0092] If not, the control of the vacuum pump starts running until the operating length of the vacuum pump reaches the first preset length of time, the control of the vacuum pump stops running.

[0093] It should be noted that, in the present embodiment, the first preset pressure threshold is greater than the second preset pressure threshold, the first preset pressure threshold may be set according to the upper pressure limit of drawer 1, the second preset pressure threshold may be set according to the lower pressure limit of drawer 1, if the internal pressure of the drawer 1 is greater than the first preset pressure threshold, it will affect the freshness preservation effect, at this time the drawer 1 is vacuumed for a longer time. The first preset duration may be set according to the actual needs, and is not limited here. For example, the first preset duration may be set to 5 minutes.

[0094] In the present embodiment, when the refrigerator enters the drawer anti-condensation mode, it will also be based on the internal pressure of drawer 1, to achieve the linkage control of the fan 2 and the vacuum pump, can timely withdraw the water vapor from the inside of drawer 1, but also make the oxygen content in the space drop, can inhibit the respiration of fruits and vegetables and oxidation reaction, thereby reducing nutrient loss, delaying the aging and corruption of ingredients, to achieve the purpose of prolonging the freshness of ingredients, ensuring the quality of food, to achieve drawer 1 preservation and avoid condensation of both, improve user experience.
