Abstract

The invention provides a refrigerator. The refrigerator comprises a refrigerator body and a packaging structure. The packaging structure comprises a first support, a second support and a heating assembly. The first support and the second support can move oppositely to clamp a packaging bag. The heating assembly is arranged in the first support. The heating assembly comprises a heating piece and a thermal protection device. The heating piece is used for heating and sealing the packaging bag. The thermal protection device and the heating piece are electrically connected to form a heating circuit. When the temperature of the thermal protection device reaches a threshold value, the thermal protection device is disconnected, and the heating circuit is disconnected. According to the refrigerator, food materials can be independently packaged, mutual pollution between the food materials is avoided, and high safety is achieved.

Description

technical field [0001] The invention relates to a household appliance, in particular to a refrigerator. Background technique [0002] A refrigerator is an appliance that maintains low temperatures by keeping food or other items in a constant cold state to avoid spoilage. With the improvement of people's living standards, people's demand for food preservation is also increasing. [0003] Generally, a variety of food materials are often stored inside the refrigerator, such as vegetables, fruits, cooked food, pasta and the like. For different food materials, certain odors or volatiles are often emitted, and these odors and volatiles often pollute the interior of the refrigerator. Therefore, multiple ingredients are placed in the refrigerator at the same time, which will cause mutual contamination of the ingredients in the refrigerator. Contents of the invention [0004] The invention provides a refrigerator capable of avoiding mutual contamination among foodstuffs. [000...
