Embodiment

[0010] Embodiment: A two-way air inlet centrifugal wind wheel, including an impeller core disk 1, a wheel rim 2 and several blades 3, the impeller core disk is fixed to the output shaft of the motor, and several blades are annularly distributed on both the impeller core disk and the wheel rim Between, one end of each blade is fixed to the wheel rim, and the other end of each blade is fixed to the edge 11 of the impeller core disk and radially protrudes from the edge of the impeller core disk and is exposed outside the edge of the impeller core disk, that is, the outer edge of the blade air outlet side The diameter of the circle where it is located is greater than the diameter of the circle where the edge of the impeller core disk is located, so that a gap 4 is formed between the other end of the impeller and the impeller core disk, and air can enter the centrifugal wind wheel through this gap, that is, compared with the traditional centrifugal wind wheel, the two-way air intake ...

Abstract

The invention discloses a two-way air intake centrifugal wind wheel. The other end of each blade of the two-way air intake centrifugal wind wheel is fixed on the edge of an impeller core disc, extends out of the edge of the impeller core disc in a radial direction and is exposed outside the edge of the impeller core disc, i.e. the diameter of a circle in which the outer edge of the air outlet side of the blade is located is lager than that of a circle in which the edge of the impeller core disc is located, so that a gap is formed between the other end of the impeller and the impeller core disc, and air can enter into the centrifugal wind wheel by the gap. Compared with the traditional single-way air intake centrifugal wind wheel, the centrifugal wind wheel of the invention is added with a reversed air inlet so as to achieve two-way air intake, thereby improving air quantity parameters on an equal footing. The invention has simple structure and is easy to implement.

Description

technical field [0001] The invention relates to a centrifugal wind wheel, in particular to a centrifugal wind wheel capable of two-way air intake. Background technique [0002] The working principle of the fan equipped with a centrifugal wind wheel is: the motor drives the centrifugal wind wheel to rotate, the blades in the centrifugal wind wheel force the gas to rotate, do work on the gas, and increase the energy of the gas. The surrounding area is thrown out, and the speed energy is converted into pressure energy through the volute casing. When the gas in the centrifugal wind wheel is discharged, the pressure in the centrifugal wind wheel is lower than the pressure at the air inlet, and the new gas is released under the action of the pressure difference. Inhaled into the centrifugal wind wheel, the gas is continuously sucked in and discharged. The structure of a traditional centrifugal wind wheel is as follows: it includes an impeller core disc, a wheel hoop and several b...
