In one embodiment, the refrigerator further includes a humidifier for increasing the humidity in the refrigerating chamber 10. Since the humidity of the air entering the freezing chamber 20 is reduced, the humidity of the air entering the refrigerating chamber 10 from the freezing chamber 20 is necessarily reduced in the refrigerating chamber 10, and therefore, in order to ensure the proper humidity of the refrigerating chamber 10, the refrigerating chamber 10 is humidified by a heater, and the humidity of the refrigerating chamber 10 can be adjusted better.
In one embodiment, as shown in fig. 1, the refrigerator further includes an evaporator 30, an outlet of the first air duct 100 and an inlet of the second air duct 200 are both disposed in the freezing chamber 20, and the evaporator 30 is disposed between the outlet of the first air duct 100 and the inlet of the second air duct 200. The temperature in the freezing chamber 20 can be reduced through the evaporator 30, the freezing chamber 20 is kept in a freezing state, meanwhile, air entering the freezing chamber 20 can be dehumidified, the evaporator 30 is located between the outlet of the first branch pipe and the inlet of the second air pipe 200, the humidity can be reduced in the process that the air enters the second branch pipe again through the first branch pipe, and the follow-up temperature memorability adjustment in the refrigerating chamber 10 is facilitated.
As shown in fig. 2, in an embodiment, a humidity control method is provided, which adopts the above humidity control structure, and includes the following steps:
detecting the humidity in the refrigerating chamber 10 to obtain real-time humidity;
comparing the real-time humidity with a preset humidity range;
if the real-time humidity is larger than the maximum value of the preset humidity range, dehumidifying the refrigerating chamber 10;
if the real-time humidity is within the preset humidity range, the humidity control treatment and the dehumidification treatment are alternately performed on the refrigerating chamber 10,
the air mix door reduces the air volume ratio of the refrigerating room 10 delivered from the branch pipe 300 when dehumidifying the refrigerating room 10, and increases the air volume ratio of the refrigerating room 10 delivered from the branch pipe 300 when humidity-controlling the refrigerating room 10.
The humidity control method compares the real-time humidity measured in the refrigerating chamber 10 with a preset humidity range, when the real-time humidity is higher, the air volume ratio conveyed to the refrigerating chamber 10 by the branch pipe 300 is reduced through the mixing air door, at the moment, more low-humidity air enters the refrigerating chamber 10, the humidity in the refrigerating chamber 10 can be reduced at a higher speed, and when the real-time humidity is more appropriate, the dehumidifying treatment and the humidity control treatment can be alternately carried out on the refrigerating chamber 10, wherein the air volume ratio conveyed to the refrigerating chamber 10 by the branch pipe 300 can be increased through the mixing air door during the humidity control treatment, the quantity of low-humidity air entering the refrigerating chamber 10 can be reduced, the falling speed of the humidity in the refrigerating chamber 10 is slowed down, therefore, the humidity control method can adjust the humidity in the refrigerating chamber 10 and control the change speed of the humidity, the control is more accurate, and the use effect is good.
Alternatively, in the above-mentioned alternate humidity control treatment and dehumidification treatment of the refrigerating chamber 10, the humidity control treatment of the refrigerating chamber 10 may be performed once or at least twice, and the dehumidification treatment of the refrigerating chamber 10 may be performed once or at least twice, for example, two humidity control treatments and one dehumidification treatment are performed, and the time point of the dehumidification treatment is located between the two humidity control treatments.
Optionally, the time of the humidity control treatment and the time of the dehumidification treatment are the same or different according to the dehumidification requirement.
Optionally, the preset humidity range may be set according to different articles, for example, the articles placed in the refrigerating chamber 10 are fruits, and the preset humidity range may be set to 80% to 95%; the predetermined humidity range may be set to 30% to 50% for articles such as cakes and tea to be placed in the refrigerating compartment 10.
In one embodiment, when the refrigerating compartment 10 is dehumidified, the amount of air delivered to the freezing compartment 20 by the first duct 100 is increased; when the humidity control process is performed on the refrigerating compartment 10, the amount of air delivered to the freezing compartment 20 by the first duct 100 is reduced. Because the humidity in the refrigerating chamber 10 needs to be reduced as soon as possible during dehumidification, the air volume of the first air duct 100 entering the freezing chamber 20 is increased, the total circulating air volume can be increased for accelerating the dehumidification speed, and the air volume of the first air duct 100 entering the freezing chamber 20 is reduced during humidity control, so that the dehumidification speed can be slowed down, excessive humidity is avoided, and the humidity is kept in a proper range.
In one embodiment, as shown in fig. 2, if the real-time humidity is less than the minimum value of the preset humidity range, the humidity control process is performed on the refrigerating chamber 10. At this time, the humidity is low, and therefore, it is necessary to reduce the total circulating air volume, slow down the dehumidification speed, and prevent the humidity in the refrigerating compartment 10 from being too low.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
