Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of short air supply distance. The inventor has searched and tested many methods, and has done a lot by increasing the motor speed, adjusting the size of the fan blades, changing the overall size of the product, changing the shape of the air outlet and air inlet, etc. The working prototypes were compared and tested and analyzed, and it was found that no beneficial effect was obtained, either the noise became larger or the product size was too large

Abstract

The invention discloses a novel axial-flow fan blade air conditioner fan. The novel axial-flow fan blade air conditioner fan comprises a fan body composed of a front shell and a rear shell and axial-flow fan blades, an air inlet is formed in the rear side face of the rear shell, and an air outlet is formed in the front side face of the front shell; and the axial-flow fan blades are arranged in the fan body, and a rotating shaft of the axial-flow fan blades is perpendicular to the middle position of the air outlet. The novel axial-flow fan blade air conditioner fan is characterized in that an air gathering device is arranged between the air outlet and the axial flow fan blades and comprises an air gathering ring and an air gathering grid, the air gathering ring is arranged on the outer side of the edge of the air gathering grid, the axial-flow fan blades are arranged towards the air gathering ring, and the rotating diameter of the axial-flow fan blades is smaller than the inner diameter of the air gathering ring. According to the novel axial-flow fan blade air conditioner fan, the air gathering device is arranged between the air outlet and the axial-flow fan blades, axial flow air is gathered and exhausted through the air gathering grid, and compared with an existing air conditioner fan, the air supply distance can be increased by 40% or above.

Description

technical field [0001] The invention relates to the technical field of evaporative air conditioning, in particular to a novel axial-flow blade air-conditioning fan. Background technique [0002] Water evaporative air-conditioning fan (hereinafter referred to as air-conditioning fan) is an energy-saving and cooling product. Its principle is that a water evaporation carrier is installed at the air inlet of the fan assembly, and the fan drives air through the water evaporation carrier to promote water to evaporate at room temperature. The water evaporates and absorbs the heat of gasification to cool the water and air. The ungasified water flows back to the water tank for recycling, and the cooled air is blown out through the air duct and the air outlet, directly giving people a feeling of coolness. Because it does not use a compressor, but uses a common fan, so the energy consumption is low, the cost is low, and it is favored by consumers in the hot summer. The structure of th...
