Problems solved by technology

The other type of fan also has an air inlet on the right side, and the motor is installed on the fan through a beam. However, due to the relatively large diameter of the motor currently used, the motor and the beam occupy most of the area of ​​the air inlet, resulting in the actual air intake from the right side of the fan. Therefore, the air intake effect of these two types of fans is not much different. The fan system composed of these two types of fans has common shortcomings: 1. The space on the righ

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0015] As shown in the figure, the double-sided uniform air intake fan system of this range hood includes a main engine 1, an impeller 4 and a fan 5, and the motor 7 is fixedly connected with three motor brackets 6 through first bolts 16. The motor bracket 6 Fixedly connected to the fan 5, the fan 5 is fixedly connected to the inner wall of the main engine 1 through the first screw 17, the impeller 4 is connected to the output shaft of the motor 7, and a left air inlet chamber 14 and a right inlet chamber connected to each other are formed in the main engine 1 cavity. Wind cavity15.

[0016] Concrete structure and principle are: at first motor support 6 is installed on the motor 7, then is fixed on the blower fan 5, then impeller 4 is contained on the motor 7, fixes with block cap 2 then. The fan retaining ring 3 is fixedly installed on the fan 5 by the seco...

Abstract

The invention relates to a uniform air intake draught fan system on double-side of a fume exhaustor, comprising a main unit, impeller and draught fan, a set of motor support frames are fixedly connected onto the motor, the motor support frame is fixedly connected onto the draught fan, the draught fan is fixedly connected onto the internal wall of the main unit, the impeller is connected to the output shaft of the motor, a communicated left air intake cavity and right air intake cavity are formed inside the main unit cavity. The impeller includes an upper loop, a central loop, a bottom loop and an impeller vane, the central loop is arranged between the upper loop and the bottom loop, an impeller frame for connecting the motor output shaft is fixedly connected onto the central loop. The invention has useful effect of: 1 effectively developing right side space of the draught fan system such that uniform air intake on double-side is obtained, easily absorbing oil smoke generated by a left boiler or right boiler in cooking process; 2 sufficiently developing right side area of the draught fan system to resolve bottleneck of improving air capacity such that air capacity is improved greatly.

Description

technical field [0001] The invention relates to a fan system of a range hood, in particular to a double-sided uniform air inlet fan system for a range hood. Background technique [0002] In the prior art, there are mainly two types of fans for range hoods. One is that the right side of the fan is completely sealed, and the air intake is all on the left side. The other type of fan also has an air inlet on the right side, and the motor is installed on the fan through a beam. However, due to the relatively large diameter of the motor currently used, the motor and the beam occupy most of the area of ​​the air inlet, resulting in the actual air intake from the right side of the fan. Therefore, the air intake effect of these two types of fans is not much different. The fan system composed of these two types of fans has common shortcomings: 1. The space on the right side of the fan system is not fully utilized, and the air volume cannot always be improved. 2. The air intake is unev...
