Noise-reduction range hood of double air intake structure

Abstract

The invention relates to the technical field of kitchen utensils, and particularly relates to a noise-reduction range hood of a double air intake structure. The range hood provided by the invention comprises a box body component, a flow guide plate, a fan component and a silencing component, wherein the fan component comprises a volute; the volute is provided with a first air intake passage, a second air intake passage and an air outtake passage; the flow guide plate is mounted on the box body component; further, the flow guide plate is provided with a wind inlet. An air current entering the box body component from the wind inlet is dispersed into two ways, that is, passes through the first air intake passage and the second air intake passage respectively and then passes through the air outtake passage to flow out; a current distribution effect is good; noise is effectively reduced; meanwhile, lower flow speeds of the air currents on two sides, which are caused as the air current is centralized, are also avoided; smoke gathering areas on left and right sides in the box body component are expanded; an oil and smoke suction effect is improved; the silencing component is arranged, corresponding to the first air intake passage of the volute, in the box body component, so as to be capable of eliminating noise of a gas eddy current in the range hood, reverberation noise and radiationnoise at an air inlet, and the improvement of a noise reduction effect of the whole range hood is facilitated.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to a noise reduction range hood with a double air intake structure. Background technique [0002] The ones used in the user's family are generally double stoves, with two burners on the left and right. The cooking utensils are located on both sides of the hood, and the general range hood has only one air inlet and the air inlet is placed in the middle. It is generally difficult to suck and exhaust the oil fumes on both sides with the central air inlet. [0003] In view of the above problems, the current technical solutions generally solve the problem by increasing the left and right, front and rear dimensions of the smoke collecting cavity. The increased size of the smoke collection cavity can form a certain size of smoke control area. Generally, the larger the size, the larger the smoke control area. For example, a certain brand of series fan has a bottleneck in the incre...

Problems solved by technology

[0007] The purpose of the present invention is to provide a noise-reducing range hood with a double-intake structure, which has a simple structure, good noise reduction and noise-reduction effects, and can improve the effect of the range hood, so as to solve the problem of existing range hoods. There is only one air inlet, which has poor smoking effect, and the parallel arrangement of volutes has problems of high cost, low efficiency and high noise
