Bracket for range hood fan, range hood fan and range hood

Abstract

The invention discloses a support for a draught fan of a range hood, the draught fan of the range hood and the range hood, the support for the draught fan of the range hood comprises a mounting base and a plurality of supporting leg structures evenly arranged on the side face of the mounting base at intervals, and each supporting leg structure comprises a supporting rod connected with the mounting base and a fixing base connected with the supporting rod; the angle formed between the supporting foot structures arranged at the two ends of the side face of the installation base is smaller than or equal to 200 degrees. According to the scheme, smoke is sucked in from the bottom of the air flue from bottom to top, the lower area of the air inlet is a main flowing-in channel of the smoke, and therefore the support is arranged outside the lower area of the air inlet, and it can be guaranteed that the smoke is not blocked through the arrangement; the smoke can smoothly enter the air inlet of the fan through the area without the supporting leg structure, so that the smoke inlet area is increased, the smoke inlet amount is increased, and the smoke suction effect is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a bracket for a range hood fan, a range hood fan and a range hood. Background technique [0002] In the range hood, the fan has a direct impact on the exhaust effect and working performance of the range hood. The fan mainly includes a volute, a motor, a bracket supporting the motor, and an impeller driven and rotated by the motor. [0003] Among them, the setting mode of the motor in the volute is divided into the middle position of the motor and the non-center position. In the non-center-mounted mode of the motor, the fan has an air inlet, and the air is fed through one side. In the way of placing the motor in the middle, the fan has two air inlets, and the air is fed through both sides. Compared with the single-sided air intake of the non-central motor, the double-sided air intake of the central motor increases the air intake, and the effect of absorbing oil fum...

AI Technical Summary

Problems solved by technology

[0011] The support in the prior art adopts a sheet structure, the area of ​​the windward surface is relatively large, and its own wind resistance is large, resulting in the unsmooth air intake and poor smoking effect

[0012] 4. The influence of the motor casing on the air intake

[0013] In the prior art, the motor casing covering the motor rotor is in a cylindrical convex structure, and the airflow entering from the air inlet will hit the motor casing, resulting in disordered airflow, poor discharge, and poor smoking effect
