Air conditioning equipment drain with low noise cooling fan

This creation is related to the drainage device for air conditioning equipment, and in particular to an air conditioning equipment drainage device with a low noise cooling fan.

Referring also to the Patent No. M402396 of the Republic of China, a motor housing for a drain device for a cooling or air conditioning unit, wherein during operation of the motor, hot air rises into the airflow region, and the blades of the cooling fan are subjected to the motor After being driven, the cooling fan has no shielding under the blade, and the hot air first flows under the blade of the cooling fan, and then diffuses out through the plurality of air outlets.

Due to the conventional use of the heat-dissipating fan, since the blade of the heat-dissipating fan is not shielded, the hot air directly flows under the blade of the heat-dissipating fan, causing the hot air and the blade to generate wind-disturbing disturbance, thereby causing great noise.

The main purpose of the present invention is to provide an air conditioning device drainage device with a low noise cooling fan. The ring cover is used to cover the lower edge of the plurality of oblique blades, and the hot air is first forced into the vent hole of the ring cover to eliminate the wind. The disturbance is excited, and the discharge is guided through the oblique blades to reduce the volume of the exhaust gas.

The air conditioning device drainage device with a low noise cooling fan provided by the present invention comprises: a casing consisting of a base and a cover body, and a plurality of vent holes are arranged around the cover body; a motor, the cover body of the housing is provided; a cooling fan is arranged above a plate body is arranged, a plurality of oblique blades are arranged around the lower edge of the plate body, a ring cover forms a vent hole at the center, and the ring cover is used to cover the lower edge of the oblique blade; a drain casing, the inner concave surface is upwardly arranged In the base; a drainage blade is received in the drainage housing; and a rotating shaft is disposed in the housing, and the cooling fan center, the motor center and the drainage blade center are sequentially disposed and interlocked.

Thereby, the ring cover of the present invention is used to cover the lower edges of the inclined vanes to prevent the hot air from flowing directly from the downward direction from the downward direction, thereby generating a wind-cutting disturbance, first forcing all the hot air to flow into the ring cover. In the air hole, the wind cut disturbance is eliminated, and the discharge is guided through the oblique blades to reduce the volume of the exhaust gas.

In order to explain in detail the technical features of the present invention, the following preferred embodiments are described with reference to the following drawings, wherein: as shown in FIGS. 1 to 4, a preferred embodiment of the present invention is provided. The air conditioner drainage device 10 having a low-noise cooling fan is mainly composed of a casing 11, a motor 21, a cooling fan 31, a drain casing 41, a drainage blade 51, and a rotating shaft 61, wherein: the casing 11 , consisting of a base 12 and a cover 14, the cover 14 weeks A plurality of venting holes 16 are provided, as shown in Fig. 1.

The motor 21 is disposed inside the cover 14 of the casing 11, as shown in Fig. 2.

The heat dissipating fan 31 has a plurality of oblique vanes 32 in the periphery thereof. As shown in FIGS. 2 to 3, the radiating fan 31 is disposed in the lid body 14 and above the motor 21. In the preferred embodiment, as shown in FIG. 4, a plate body 34 is disposed above the cooling fan 31. A plurality of oblique blades 32 are disposed around the lower edge of the plate body 34. A ring cover 36 defines a vent hole at the center. 38. The ring cover 36 is configured to cover the lower edges of the diagonal vanes 32. In the preferred embodiment, the cross-sectional edge of the inner edge of the vent hole 38 has an arc shape, as shown in FIG. 4, and the vent hole 38 has a smaller diameter than the inner edge of the oblique blade 32. The heat dissipation fan 31 has a convex ring 39 located at the outer edge of the ring cover 36.

The drain casing 41 is recessed upward and disposed in the base 12 as shown in FIG.

The drain blade 51 is housed in the drain casing 41 as shown in Fig. 2.

The rotating shaft 61 is disposed in the casing 11, and as shown in Fig. 2, the center of the cooling fan 31, the center of the motor 21, and the drain blade 51 are sequentially inserted and interlocked.

The structure of a preferred embodiment of the present invention has been described above, and the state of use of a preferred embodiment of the present invention will now be described.

Referring to FIG. 2, when the hot air is discharged, the cooling fan 31 is driven by the motor 21, since the hot air is blocked by the ring cover 36 of the cooling fan 31 to prevent the hot air from being inclined by the direction. The blade 32 directly flows downward to generate a wind-cut disturbance. As shown in Fig. 4, the hot air is first forced to flow from the inner edge of the vent hole 38 of the ring cover 36 to eliminate the wind-cut disturbance, as shown in Fig. 2, The discharge is guided to the exhaust holes 16 via the inclined vanes 32 and diffused out to reduce the volume of the exhaust gas.

As can be seen from the above, the achievable effect of the present invention is that the problem of the great noise generated by the discharge of hot air in the prior art is solved. The ring cover 36 of the present invention is used to cover the lower edge of the oblique blade 32, and is forced first. The hot air flows all the way into the vent hole 38 of the ring cover 36 to eliminate the wind cut disturbance, and then the discharge is guided through the inclined blades 32 to reduce the volume of the exhaust gas.
