Benefits of technology

The present invention is about a device that reduces noise in air conditioning equipment. It involves a drainage device with a fan that has a ring cap to prevent wind shear turbulence and direct hot air into the fan. This results in a quieter air exhaust and a more efficient air conditioning system.

Problems solved by technology

According to this prior art design, the space blow the fan blades of the radiator fan is an open space through which the induced flow of hot air flows directly over the fan blades to generate wind shear turbulence, causing a high level of noise.

Embodiment Construction

[0014]Referring to FIGS. 1-4, a drainage device with a low-noise radiator fan for air-conditioning equipment in accordance with the present invention is shown. As illustrated, the drainage device 10 comprises a housing 11, a motor 21, a radiator fan 31, a drainage shell 41, and a drainage blade 51.

[0015]The housing 11 comprises a bottom shell 12 and a cover shell 14. The cover shell 14 has a plurality of vent holes 16, as shown in FIG. 1. The motor 21 is mounted in the cover shell 14 inside the housing 11, as shown in FIG. 2. The motor 21 has a driving shaft 61.

[0016]The motor 21 is mounted in the cover shell 14 inside the housing 11, as shown in FIG. 2. The motor 21 has a driving shaft 61.

[0017]The radiator fan 31 comprises a plurality of fan blades 32 circumferential bowed and equiangularly arranged around the periphery thereof, as shown in FIGS. 2 and 3. Further, the radiator fan 31 is mounted in the cover shell 14 inside the housing 11, and disposed above the motor 21. In this e...

Abstract

A drainage device with a low-noise radiator fan for air-conditioning equipment is disclosed to include a housing, a motor, a radiator fan, a drainage shell, and a drainage blade. The motor is mounted in the housing. The radiator fan includes a plate member, fan blades arranged at a bottom side of the plate member around the border area, and a ring cap covering the fan blades at a bottom side and having an air passage hole at the center thereof. Thus, the ring cap forces hot air to flow through the air passage hole of the ring cap into the inside of the radiator fan to prevent wind shear disturbance, enabling the intake flow of hot air to be further guided by the fan blades to the atmosphere to significantly reduce the level of air exhaust noise.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to air conditioning drains and more particularly, to a drainage device with a low-noise radiator fan for air-conditioning equipment.[0003]2. Description of the Related Art[0004]Taiwan patent M4023962 discloses a motor cover used in a drainage device for cooling or air-conditioning equipment. During rotation of the motor, hot air is induced to flow upwards into the airflow area. At this time, the induced flow of hot air flows upwardly through the fan blades of the radiator fan and multiple air vents toward the atmosphere.[0005]According to this prior art design, the space blow the fan blades of the radiator fan is an open space through which the induced flow of hot air flows directly over the fan blades to generate wind shear turbulence, causing a high level of noise.SUMMARY OF THE INVENTION[0006]The present invention has been accomplished under the circumstances in view. It is the main obje...
