Problems solved by technology

Wherein, the acute angle between the plane formed between the inner ring and the outer ring of the first air outlet component and the plane where the fan is located is 65-80 degrees; the diameter of the hole of the air inlet on the base increases sequentially from top to bottom, There is an air outlet on the second air outlet part, and the size of the second air outlet at the same distance as the first air outlet part is the same, but the high-speed motor is still used in this patent, and there is still machine noise generated by the rotation of the motor itself and vibration
Therefore, the fan in the prior art has the disadvantages of high noise, difficulty in cleaning, and high energy consumption

Embodiment 1

[0051] Such as figure 1 As shown, the bladeless fan of the low-speed supercharger impeller includes an upper part, a middle part and a lower part mechanically connected, wherein the upper part is an air outlet assembly, and the middle part includes a cylindrical fan housing 2, a supercharger impeller assembly, and an air intake assembly. And motor 3, the bottom is base 1. Wherein, the casing 2 has an air inlet and an air outlet, the air outlet assembly is arranged at the air outlet, and the air inlet assembly is arranged at the air inlet. Such as figure 1 with figure 2 As shown, there is a remote control panel 11 on the base 1. The remote control panel 11 is also called an electronic induction receiver, which is used to receive the signal sent by the remote controller and control the speed of the motor. The speed of the motor is to ensure that the fan outlet The basis of the size of the wind, the greater the speed, the greater the wind blown by the fan. The connecting par...

Embodiment 2

[0061] The structural principle of this embodiment is basically the same as that of Embodiment 1, the difference is that, as image 3 As shown, the booster impeller assembly adopts a single-stage thickened axial-flow impeller. The positional relationship between most of the components in this embodiment is the same as that in the first embodiment of the booster impeller assembly. With a single-stage thickened axial-flow impeller, the longer the acceleration distance of the air passing through the impeller, the greater the energy obtained. For example, the thickness of the impeller in the past was 20mm. In this embodiment, the thickness of the impeller is increased to 40mm, and the energy of the air increases. The volume is larger than in the past, otherwise the same air volume and air pressure, the speed of the thickened impeller is much smaller. At this time, the rotating speed of the motor 3 can be reduced, and the noise will also be reduced as the rotating speed decreases....

Embodiment 3

[0063] The structural principle of this embodiment is basically the same as that of Embodiment 1, the difference is that, as Figure 4 As shown, the booster impeller assembly is a multi-stage axial flow impeller, and the relationship between other components is basically the same as that in the second embodiment. The multi-stage axial-flow impeller can realize large wind output at low speed, thus reducing noise. The multi-stage axial-flow impeller is the same as the single-stage thickened axial-flow impeller. The only difference is that the single-stage thickened axial-flow impeller can increase the energy at one time, while the multi-stage axial-flow impeller can increase the energy in multiple times. , the results are designed for lower speeds.

Abstract

The invention provides a bladeless fan with a low-speed booster impeller, which belongs to the technical field of electric appliances. It solves the problems of high noise, difficulty in cleaning and high energy consumption of the existing bladeless fan. The bladeless fan with a low-speed supercharged impeller includes a base and a cylindrical casing arranged above the base. The casing is provided with an air inlet and an air outlet, and a supercharged impeller assembly and a drive for the supercharger are arranged in the casing. The motor for the impeller assembly is provided with an air inlet assembly that can reduce air noise at the air inlet, and an air outlet assembly that can increase the draft effect at the air outlet. The invention has the advantages of good performance, low noise, easy cleaning, low energy consumption, large wind outlet angle and the like.

Description

technical field [0001] The invention belongs to the technical field of electrical appliances, and relates to a fan, in particular to a bladeless fan with a low-speed booster impeller. Background technique [0002] A fan is a cooling device that removes heat by circulating and moving air, and is a traditional, eco-friendly indoor appliance. Fans can be divided into three types according to the different types of air outlets. One is an axial flow fan that directly disturbs the wind flow through multiple fan blades that rotate around the axis driven by a motor. This fan is a traditional common electric fan. Forms, including ceiling fans and table fans and other structural fans, the fan blades of this fan are mostly exposed outside, in order to prevent the fan blades from falling off and hurting people, or to prevent external objects from touching the fan blades, some protective sleeves are usually set around the fan blades Or isolate the device, or hang the fan high, away from...
