Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of refrigerator, especially a refrigerator based on hall sensor. BACKGROUND

[0002] Refrigerator, one of the indispensable appliances in modern families, greatly improves our quality of life with its outstanding preservation and refrigeration technology. It effectively reduces the internal temperature through the built-in refrigeration system, providing a low-temperature storage environment for food, thereby delaying food spoilage and maintaining the freshness and nutrition of food. Refrigerator design is diverse, from simple single-door to luxurious multi-door, meeting the needs of different families. Some high-end models are also equipped with advanced functions such as intelligent temperature control, rapid freezing, holiday mode, allowing users to enjoy a more convenient and intelligent life experience. In addition, environmental protection and energy saving are also important considerations in modern refrigerator design, using high-efficiency compressors and insulation materials to reduce energy consumption and meet the concept of green living. In short, the refrigerator is not only a practical tool in the kitchen, but also an important partner in improving the quality of life and ensuring food safety.

[0003] According to the search, the Chinese patent with the publication number CN209131225U discloses a refrigerator fan control system and a refrigerator, wherein the refrigerator fan control system includes a freezing fan located in the refrigerator, a magnetic control switch installed on the first door of the refrigerator, and a magnetic element installed on the second door of the refrigerator. The magnetic control switch is electrically connected to the freezing fan to control the start and stop of the freezing fan. When the distance between the magnetic element and the magnetic control switch is within the preset distance, the magnetic element turns on the magnetic control switch. When the distance between the magnetic element and the magnetic control switch is outside the preset distance, the magnetic element turns off the magnetic control switch. When the first door and the second door are closed at the same time, the distance between the magnetic element and the magnetic control switch is within the preset distance.

[0004] The refrigerator in the above-mentioned prior art uses a door magnetic structure to achieve start and stop control of the refrigerator freezing fan, thereby meeting the need for reducing energy consumption. However, the current technology uses a door magnetic induction on-off structure that is either installed outside the refrigerator or inside the refrigerator shell. First, the door magnetic sensor installed outside the shell is not protected and is easily damaged by collision, especially when the refrigerator is being moved and the door magnetic sensor is accidentally damaged. Second, although the installation inside the shell has good protection effect, it needs to open the corresponding position of the shell of the refrigerator when disassembling, and then the door magnetic sensor can be disassembled and replaced.
