Document Type and Number:
WIPO Patent Application WO/2021/238218
Kind Code:
A1
Abstract:
A control method for a modified atmosphere preservation apparatus, wherein the modified atmosphere preservation apparatus comprises an accommodating box, a drawer, a modified atmosphere film, a modified atmosphere power assembly, a gas concentration sensor, a human body detection sensor, and a control unit. The control method comprises: when a space formed by the accommodating box and the drawer is sealed, the gas concentration sensor obtains the concentration of a preservation gas contained in the space formed by the accommodating box and the drawer, and sends same to the control unit; the control unit determines whether the concentration of the preservation gas is lower than a preset concentration threshold; if the concentration of the preservation gas is lower than the preset concentration threshold, the human body detection sensor determines whether a human body exists around the modified atmosphere preservation apparatus; and if no human body exists around the modified atmosphere preservation apparatus, the control unit controls and starts the modified atmosphere power assembly to adjust the concentration of the preservation gas contained in the space formed by the accommodating box and the drawer, so as to make the concentration of the preservation gas reach the preset concentration threshold.
