Description

Technical Field

[0001] The utility model relates to the technical field of ozone disinfection, in particular to a refrigerator with an ozone disinfection function. Background Art

[0002] Refrigerators have become a must-have in household appliances, and their functions are becoming more and more diverse. After meeting the needs of refrigerator refrigeration function, existing refrigerators also need to have ice-making function. Early refrigerators could only store food by cooling, and their functions were relatively simple, which could no longer meet the needs of modern life. After the ice-making function was embedded in the refrigerator, the safety and hygiene of ice-making needed to be considered. Directly using tap water to make ice obviously does not meet the requirements for preparing edible ice. Most existing refrigerators do not have ice-making function. Refrigerators with ice-making function lack water purification and disinfection means. Long-term use of internal pipes is prone to bacteria and contamination, and edible ice cannot be prepared. A multifunctional refrigerator that can prepare edible ice is now needed.

[0003] The existing patent application with publication number CN113108537A discloses a deodorizing and sterilizing device and a refrigerator, a refrigerator system, and a refrigerator control method, which relates to the field of refrigerator deodorizing and sterilizing technology, including a device body, which is a circular shell, and the shell includes a box cover, a liner box, and an inner cavity formed by the two. A fan is provided at the center of the inner cavity, and a multi-metal catalyst module is provided at the air outlet. An ozone generator is provided between the multi-metal catalyst module and the fan. The refrigerator deodorizing and sterilizing is achieved by the synergistic effect of the multi-metal catalyst, the ozone generator, and the fan, while solving the odor and safety hazards caused by the presence of ozone. The ozone in the refrigerator is only used for sterilization, lacks the ice-making function and the sterilization of the internal water supply pipe, and cannot meet the demand for making edible ice.
