Extractor hood with double air inflow structures

Abstract

The invention relates to the technical field of kitchen utensils, in particular to an extractor hood with double air inflow structures. The extractor hood comprises a box body assembly and a draught fan assembly; the draught fan assembly comprises a volute which is provided with a first air inflow channel, a second air inflow channel and an air outflow channel; the box body assembly comprises a main case and a rack located above the main case; the lower end of the volute is located in the main case; at least part of the upper end of the volute stretches out of the main case; the portion stretching out of the main case is located in the rack; the volute is vertically arranged in the box body assembly in a half-embedded manner; the flue gas sucking and exhausting resistance is small, the whole machine noise is low, the air volume and air pressure loss caused because the box body space is small is avoided, and improving of the lampblack sucking effect is facilitated; and besides, the volute is provided with the two air inflow channels, so that air flow entering the box body is made to be dispersed into two paths, noise is effectively lowered, it is also avoided that because of gas flow concentration, the air flow speed on the two sides is low, the smoke holding areas on the left side and the right side in the box body are widened, and therefore the lampblack sucking effect is effectively improved.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to a range hood with a double air intake structure. Background technique [0002] like Figure 1 to Figure 4 As shown, the range hood 100 is mainly composed of a check valve 101, a box body, a deflector 102, a condensation plate 103, an air inlet net 105, an oil cup 104 and other components. It is mainly composed of volute 107, motor 108, impeller 109 and other components; wherein, the flue gas enters from the surrounding edges of the deflector 102, and the specific flue gas flow direction 106 can be referred to image 3 , and the volute 107 is arranged obliquely so that the distance between the air inlet of the volute 107 and the rising smoke is closer, which is beneficial to enhance the smoking effect. However, if the volute 107 is arranged obliquely, the outlet of the volute 107 will have a bend, which will cause loss of air volume, low efficiency, and cannot cope with ...

Problems solved by technology

[0008] The object of the present invention is to provide a range hood with a double air intake structure, which has a simple structure, good appearance, good noise reduction effect and can improve the effect of the range hood, so as to solve the problem that the existing range hood only has one air inlet. Poor smoking effect and high cost, low efficiency, and limited increase in smoking effect under high back pressure
