Description

Technical Field

[0001] The utility model relates to the technical field of dehumidifier accessories, in particular to a fan capable of realizing rapid disassembly. Background Art

[0002] Dehumidifiers are also called dehumidifiers, dryers, and dehumidifiers. They can generally be divided into two categories: civil dehumidifiers and industrial dehumidifiers. They are part of an air-conditioned home. Usually, a conventional dehumidifier consists of a compressor, a heat exchanger, a fan, a water container, a casing, and a controller. When the dehumidifier is working, the fan draws humid air into the machine, passes through the heat exchanger, and the water molecules in the air condense into water droplets. The treated dry air is discharged from the machine. This cycle keeps the indoor humidity at an appropriate relative humidity.

[0003] The fan is one of the most important core components of the dehumidifier and also accounts for a large part of the cost. Conventional fans are purchased from fan factories as finished products, which are not only expensive but also have a long procurement cycle and cannot meet customers' short-term delivery requirements. Utility Model Content

[0006] A fan volute is provided at the rear end of the fan connection box cover plate, a volute cover is provided at the rear end of the fan volute, and an impeller is movably provided inside the fan volute;

[0007] A through hole is provided in the middle of the volute cover plate, a motor connecting plate is provided on the rear end surface of the volute cover plate, a motor is mounted on the motor connecting plate, and the motor is connected to the impeller through a coupling;

[0008] The volute cover plate, the fan volute and the fan connection box cover plate are split structures.

[0009] Preferably, the fan connection box cover plate and the volute cover plate are evenly provided with strip-shaped slots on the outer circle of the through hole.

[0010] Preferably, the fan volute is a multi-section folding structure, and metal inserts are symmetrically provided on the edge of the fan volute.

[0011] Preferably, the fan volute is plug-connected with corresponding strip-shaped slots provided on the fan connection box cover and the volute cover through corresponding metal inserts on both sides.

[0012] Preferably, a head cover is provided at one end of the fan volute, and a connecting piece is provided at the other end of the fan volute. Metal inserts with a "concave" structure are provided on both sides of the connecting piece, and metal inserts are provided at the "concave" openings on both sides of the head cover corresponding to the "concave" structure.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the fan that can be quickly disassembled can be quickly disassembled and assembled. It only needs to remove the corresponding screws, and the metal insert only needs to be bent and tilted to achieve disassembly. At the same time, the impeller inside can be repaired or replaced to meet the needs of different air volumes, which is convenient and simple. The traditional purchased integrated fan cannot be disassembled, let alone replace the impeller. In addition, the fan has a low production cost, a short delivery time, simple installation, a high fault tolerance rate, and more convenient later maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
