Problems solved by technology

[0003] Fresh air fans are mainly divided into two types: exhaust air fresh air fans and supply air fresh air fans. In the fresh air fresh air fans, they are divided into pipeline fresh air and wall-mounted fresh air. It is suitable for industrial or large-area office areas. At present, there are both ducted fresh air and wall-mounted fresh air in the home. Ducted fresh air will form dust in the pipe after a long time, and it is difficult to clean, so it will damage the room during long-term use. form secondary pollution

Embodiment 1

[0033] This embodiment discloses an air duct for fresh air fans, including a quiet air duct 16 and a spiral air duct 17, and the spiral air duct 17 adopts a spiral design. The spiral is a constant velocity spiral. The spiral air duct 17 adopts a section on the spiral, and the angle difference between the starting point and the end point of this section is 190°. The silent air duct 16 is a protrusion on the side wall of the fresh air machine. There are two connection points between the silent air duct 16 and the side wall, which are point A and point B respectively. Point A connects the silent air duct 16 and the spiral air duct 17 at the same time. The highest point of the protrusion is point C, and the line AB is a straight line , make a vertical line from point C to line AB to form point D, the length of CD is X, the width of the fresh air machine is U, X:U is 1:4, the length of BD is Z, the length of AD is Y, and the length of the fresh air machine is The height is V, (Z+...

Abstract

The invention discloses an air duct for a ventilator. The air duct comprises a silent air duct and a spiral air duct, wherein the spiral air duct adopts spiral line design, the spiral line is a constant-speed spiral line or an equiangular spiral line, the spiral air duct adopts one section on the spiral line, and the angle difference between a starting point and an end point of the section rangesfrom 190 degrees to 260 degrees. According to the air duct, one section of the spiral line is selected, the silent air duct is matched, so that the air volume of the ventilator is increased, meanwhilethe noise of the ventilator is reduced, and the size of the ventilator is greatly reduced.

Description

technical field [0001] The invention relates to the field of fresh air blowers, in particular to an air duct for fresh air blowers. Background technique [0002] The fresh air fan is an effective air purification equipment that can circulate the indoor air. On the one hand, the indoor dirty air is discharged outside, and on the other hand, the fresh outdoor air is sterilized, disinfected, filtered and other measures, and then input into the room. , so that the room is fresh and clean air all the time. The fresh air fan uses the patented technology of fresh air convection to make the room in a slightly positive pressure state, thereby preventing the outdoor air from entering from other outlets. Through independent air supply and induced air, the indoor air can be convected, thereby maximizing the indoor air replacement. The built-in multifunctional purification system of the fresh air fan ensures that the air entering the room is clean and healthy. [0003] Fresh air fans a...
