Description

Vacuum Blender { VACUUM BLENDER } The present invention relates to a vacuum blender, and more particularly to a vacuum blender for detecting backflow of fine water or moisture during operation of the vacuum blender and preventing the fine water, etc. from entering the vacuum pump. A blender is one of the most widely used electrical appliances in households today; it allows food items such as fruits, vegetables, and grains to be placed inside a mixing container and finely ground using a rotating blade installed at the bottom of the grinding container, making the food ready for consumption. Conventional blenders place food to be ground into the grinding container, close the lid, and rotate the blades using a high-speed motor; during this process, the air inside the container, the ground food, and liquids are mixed at high speed, generating a large amount of foam. For example, when fruits such as bananas and tomatoes are put into a blender and ground, a large amount of bubbles are produced at the top of the fruit juice. This not only degrades the taste and texture when drinking fruit juice, but also means that a significant portion of the nutrients are destroyed because the fruit fiber has already oxidized during the grinding process. Furthermore, if food must be stored rather than consumed immediately after grinding, leaving it exposed to air accelerates the oxidation process, which in turn speeds up the destruction of fiber and nutrients, causes discoloration and a decline in freshness, and leads to separation of layers between the food and the air. As such, there was a problem in that food ground by a blender was difficult to store for a long period if not consumed immediately. To address these issues, vacuum blenders with various structures have recently been developed and released. When liquid food is placed inside the grinding container of a vacuum blender and ground, fine food particles are often drawn into the vacuum pump (backflow) by vacuum suction, frequently causing the vacuum pump and pressure sensor to malfunction. As described above, in order to prevent the backflow of food containing liquid, there was a problem with the use of the blender where the maximum amount of food that can be put in the grinding container is marked, or where the user must visually check whether backflow is occurring during operation.
