AI Technical Summary

Technical Problem

Existing ultrasonic atomization humidification technology for refrigerators suffers from lag in humidity control within the refrigerator compartment and issues of insufficient or excessive humidification due to changes in available volume, which affect the preservation of food.

Method used

By installing humidity and available volume sensors in the refrigerator, and combining them with the controller to monitor humidity and available volume in real time, the number of humidification cycles and duration of operation of the humidification module are dynamically adjusted to achieve adaptive humidification control.

Benefits of technology

It can maintain a suitable humidity range under different available volumes, solving the problems of insufficient or excessive humidification and improving the preservation effect of food.

Abstract

The application discloses a refrigerator and a humidification control method. The method comprises the following steps: after refrigeration is completed, the humidity of the refrigeration chamber collected by a humidity sensor is obtained, and the available volume in the refrigeration chamber at the current time is obtained; if the humidity in the refrigeration chamber is less than a first preset humidity threshold, the target cycle number is determined according to the available volume in the refrigeration chamber, wherein the available volume in the refrigeration chamber is positively correlated with the target cycle number; the humidification module is controlled to periodically run until the cumulative cycle number reaches the target cycle number or the humidity in the refrigeration chamber rises to be greater than a second preset humidity threshold. The application sets the available volume to be positively correlated with the target humidification cycle number, so that the humidification control strategy can be self-adapted to the actual loading state of the refrigeration chamber, the problems of insufficient humidification or excessive humidification leading to condensation caused by the available volume are solved, and the food preservation effect level is improved.
