Description

Circulating device for uniformly disturbing and filtering air

The present invention relates to the technical field of the structure of an air circulation fan, in particular to a rapid convection of hot and cold air in the room to improve the cooling efficiency of the cold air, and to filter the air of the circulating convection to improve the air quality. The circulation device that evenly disturbs and filters the air.

Generally, after the air conditioner is turned on, when the indoor space reaches the set temperature, the compressor of the air conditioner usually needs to continue to operate for about 15 to 20 minutes, so the power consumption is very high. At present, in order to shorten the cooling time of the indoor space, an indoor ceiling fan is usually installed on the ceiling of the room to promote the convection of the hot and cold air in the indoor space.

The structure of the conventional indoor ceiling fan, as shown in Taiwan Patent No. M362310, is mainly based on the rotation of a plurality of blades combined with the motor linkage to blow the air above the chamber downward by the rotation of the plurality of blades. However, based on the natural law of hot air rising cold air, this kind of downward blowing is to blow the hot air above the indoors down to the inside of the room, while the indoor cold air will remain in the bottom of the room. Therefore, the effect of the air convection is very poor, and the speed of the cooling in the auxiliary chamber is very slow, and the cooling efficiency of the cold air in the room cannot be effectively improved, so the power saving effect is very small. In particular, when it blows the airflow down It is easy for the dust on the indoor floor to be blown up and fly in the air, which will further deteriorate the air quality in the room.

The structure of the conventional indoor ceiling fan has the problem that the air circulation convection effect is poor and the cooling efficiency of the cold air cannot be effectively improved, and the indoor air cannot be filtered or the indoor air quality is deteriorated.

The present invention provides a circulation device for uniformly disturbing and filtering air, comprising a fixed rod, a motor, a turbo fan and a plurality of filters. Wherein, the upper end of the fixing rod has a fixing portion for fixing on the ceiling of the room. The motor is coupled to the lower end of the fixed rod. The turbofan includes a body, an annular fan cover, and a plurality of upright blades. The seat body is coupled to the motor and is rotatable in one direction by the motor. The annular fan cover is disposed in parallel under the seat body, and a flow space between the seat body and the annular fan cover is formed in the interior of the turbo fan, and a circumferential space is formed in the flow surface and One of the annular air outlets is formed on the bottom surface to penetrate the air inlet of the flow space. The plurality of upright blades are coupled between the seat body and the annular fan in an annularly spaced arrangement such that when the turbo fan rotates, the underlying air can be drawn in by the air inlet and then discharged from the air outlet. The plurality of filter sheets are coupled to the periphery of the seat body and the annular fan cover for sealing the air outlet to filter the passing air.

The circulation device provided by the present invention for evenly disturbing and filtering the air, when the motor drives the turbo fan to rotate, can be formed by the action of a plurality of upright blades arranged at an angle and annular intervals in the turbo fan. Vortex airflow The air under the turbo fan is drawn into the flow space by the air inlet, and then the airflow in the flow space is discharged from the air outlet to the periphery of the turbo fan through the plurality of vertical blades. In this way, the cold air in the lower part of the room can be sucked and discharged to the upper part of the room to circulate and convect the hot air to achieve the purpose of effective cooling, and the circulating convection can quickly mix the hot and cold air in the room to achieve rapid and uniform cooling. The effect, in turn, can greatly increase the cooling efficiency of the cold air to save energy. In particular, when the airflow is discharged from the air outlet of the turbofan, it is filtered through the plurality of filters and then discharged, so that the air quality in the room can be greatly improved.
