Abstract

The invention provides a double-fulcrum fan structure and a cabinet air conditioner. The double-fulcrum fan structure comprises a mounting plate, a volute, a centrifugal fan and a volute cover plate.The volute is fixedly arranged on the mounting plate. A centrifugal fan mounting cavity is formed in the volute. The volute cover plate is fixedly arranged on the volute and is located outside the centrifugal fan mounting cavity. The centrifugal fan is arranged in the centrifugal fan mounting cavity. One end of the centrifugal fan is supported on the mounting plate, and the other end of the centrifugal fan is supported on the volute cover plate. The double-fulcrum fan structure and the cabinet air conditioner provided by the invention are simple and reasonable in structure, and the number of parts and screws can be effectively reduced, so that the assembling efficiency is improved; and a fan of the double-fulcrum fan structure is lower in operating noise and lower in cost, the rotation stability of fan blades of the air conditioner can be effectively ensured, the operating noise of the air conditioner is lowered, the load of a motor is reduced, and the service life of the motor is prolonged.

Description

technical field [0001] The invention belongs to the technical field of air conditioner components, and in particular relates to a double fulcrum fan structure and a cabinet type air conditioner. Background technique [0002] In the existing air-conditioning cabinets, one end of the motor is fixed on the motor mounting plate, and the other end of the fan blade is suspended in the air. Due to the heavy weight of the fan blade, this design will form a large moment of inertia, the motor load will be large, and a certain amount of air will be generated. noise; and the existing air-conditioning cabinet motor installation structure is relatively complex and has many parts, resulting in low assembly efficiency. [0003] Based on the above-mentioned technical problems in the fan structure of the air-conditioning cabinet, there is no relevant solution; therefore, it is urgent to find an effective solution to solve the above-mentioned problems. Contents of the invention [0004] The...
