Patent Searching and Data


Title:
REFRIGERATION AND FREEZING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/105306
Kind Code:
A1
Abstract:
A refrigeration and freezing device, comprising a storage drawer (100), an electrolytic oxygen removal assembly (200), a touch sensing device (500) and an electric air valve (300). The electrolytic oxygen removal assembly (200) is used for consuming oxygen in a storage space so that nitrogen-rich oxygen-deficient air is obtained in the space so as to benefit a gas atmosphere for food preservation. The intensity of the aerobic respiration of food, particularly fruits and vegetables, is decreased by means of decreasing the content of oxygen in the storage space, simultaneously ensuring basic respiratory action and preventing the anaerobic respiration of the food, thereby achieving the goal of long-term preservation of the food. When the touch sensing device (500) detects that a user is about to open the storage drawer (100), the electric air valve (300) opens a through hole on the drawer (100) so that the interior and exterior of the storage space communicate, the pressure difference between the interior and exterior of the drawer being eliminated, and thus the problem in which a drawer is difficult to open due to the mounting of the electrolytic oxygen removal assembly (200) is solved; a user may open the storage drawer (100) with less effort, and the usage experience of the user is thus improved.
