Title:
REFRIGERATOR AND REFRIGERATOR AIR DUCT PURIFICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/138268
Kind Code:
A1
Abstract:
A refrigerator and a refrigerator air duct purification system. Refrigeration air duct front foam (5) is fixed on the rear side of a refrigeration air duct back plate (3). A surface light source light-transmitting assembly (9) is arranged on the front side of the refrigeration air duct back plate (3). The refrigeration air duct front foam (5), the refrigeration air duct back plate (3) and the surface light source light-transmitting assembly (9) are provided with an air outlet (13) that penetrates front to back, an air-out end of the air outlet (13) being in communication with a refrigeration chamber. An ion generator (1), an air quality sensor (2) and an ethylene concentration sensor (6) are arranged in a main air duct. A control board is initially in a determination state, determines, by means of a door opening-closing sensor, whether a refrigeration door body is opened, and if the refrigeration door body is opened, starts an ion purification mode and controls the ion generator (1) to work for 3 hours; in the working process of the ion generator (1), the control board continuously monitors the state of the refrigeration door body, and restarts the time of the work of the ion generator (1) if the refrigeration door body is opened again; and after the ion generator (1) finishes working, the control board reenters the determination state.
