Humidity control structure, refrigerator and humidity control method

Abstract

The invention discloses a humidity control structure, a refrigerator and a humidity control method. The humidity control structure comprises a first air pipe, a second air pipe, a branch pipe and a mixing throttle. The first air pipe and the second air pipe are used for communicating with a refrigerating chamber and a freezing chamber. The air supply direction of the first air pipe is opposite tothe air supply direction of the second air pipe. The first air pipe communicates with the inlet of the branch pipe. The outlet of the branch pipe is used for communicating with the refrigerating chamber. The mixing throttle is used for adjusting the volume of air passing through the outlet of the branch pipe or the second air pipe. By means of the humidity control structure, when the air enteringthe freezing chamber enters the refrigerating chamber through the second air pipe, the humidity in the refrigerating chamber can be reduced; the branch pipe can directly convey part of the air in thefirst air pipe back into the refrigerating chamber, the humidity of the air is not changed, and thus the volume of air entering the refrigerating chamber through the branch pipe and the second air pipe is adjusted through the mixing throttle, the humidity in the refrigerating chamber can be adjusted, the changing speed of the humidity can be controlled, the humidity can be more precisely controlled, and the use effect is better.

Description

technical field [0001] The invention relates to the technical field of humidity adjustment, in particular to a humidity control structure, a refrigerator and a humidity control method. Background technique [0002] With the improvement of people's living standards, the use and function of refrigerators are given more requirements, and the humidity control of the refrigerator compartment is very important. [0003] Traditional air-cooled refrigerators have no humidity control function. The humidity in the refrigerator freezer fluctuates between 30% and 70%. The best storage humidity for most vegetables and fruits is above 80% to 90%. If the humidity is too low, vegetables and fruits will lose water. Shrinkage, and when using refrigerators to store medicines, cigarettes, tea and other items, the room humidity is low, which puts forward higher requirements for the refrigerator's ability to control humidity. [0004] At present, most refrigerator products have no humidity contr...

Problems solved by technology

[0003] Traditional air-cooled refrigerators have no humidity control function. The humidity in the refrigerator freezer fluctuates between 30% and 70%. The best storage humidity for most vegetables and fruits is above 80% to 90%. If the humidity is too low, vegetables and fruits will lose water. Shrinkage, and when using refrigerators to store medicines, cigarettes, tea and other items, the room humidity is low, which puts forward higher requirements for the refrigerator's ability to control humidity

[0004] At present, most refrigerator products have no humidity control function, and a small number of products can control the humidity of some compartments, but they cannot control the change speed of humidity, and the adjustment accuracy is low
