BLENDER WITH BIDIRECTIONAL ROTATING KNIVES Russian patent published in 2024 - IPC A47J43/46 

FIELD: household appliances.

SUBSTANCE: invention relates to a blender with bidirectional rotating blades, with possibility of rotation of a pair of blades in opposite directions with different rotation speeds. Blender with bidirectional rotating blades comprises a blade assembly including a main blade shaft, which is configured to rotate the first blade as a whole and the first main connector in the forward direction, and the reverse rotation blade shaft, which is configured to ensure the second blade rotation and a first connector of reverse rotation and has a structure which is coaxial to the main blade shaft and through which the main blade shaft passes; and a reduction gear assembly including a main gear shaft, which is configured to enable rotation of a second main connector, which is engaged with the first main connector, and the main gear in the forward direction, at least one auxiliary gear which is engaged with the main gear and rotates in the reverse direction, a ring gear for which the auxiliary gear is internal and engaged therewith, and a second reverse rotation connector which is configured to rotate integrally with the ring gear in the reverse direction and transmit the reverse rotation to the first reverse rotation connector, wherein in the inner area of one of the first main connector and the second main connector, the other of the first main connector and the second main connector is inserted for engagement therewith; first reverse rotation connector is made integral with the lower end portion of the reverse rotation blade shaft; one of the first reverse rotation connector and the second reverse rotation connector is inserted into the inner area of the other of the first reverse rotation connector and the second reverse rotation connector and is engaged therewith, in the casing, having a reduction gear assembly, there is a mounting section of the container, which is formed along the periphery of the upper end of the casing and on which a food container is located, a wall body of a recessed portion, which extends downward from the inner side end portion of the container mounting portion, and a casing top plate which extends inward from the recessed portion wall body lower end and is formed at a position below the container mounting portion; in the recessed portion, which is the inner area surrounded by the recessed portion wall body and the upper casing plate, the first main connector and the second main connector are connected to each other, and the first reverse rotation connector and the second reverse rotation connector are connected to each other; second main connector is connected to the upper end of the main gear shaft using the fastener, and after separation of the fastener from the second main connector and the main gear shaft in a position in which the container is separated upward from the casing, second main connector is separated from the main gear shaft to the upper side of the casing upper plate; knife assembly is installed to pass through the lower portion of the container for accommodating food products and is detachably connected to the container; and at separation of the casing having the reducer assembly installed therein, the reducer assembly is separated from the blade assembly.

EFFECT: easier disassembly and assembly of elements, ensuring safe use of the blender and increasing durability of its elements.
