Abstract

The invention relates to the technical field of kitchen utensils and in particular relates to a range hood. The range hood provided by the invention comprises a box body assembly and a draught fan assembly arranged in the box body assembly, wherein the box body assembly comprises a machine case and a rack which is connected with the machine case and is located above the machine case; the draught fan assembly comprises a volute and the lower part of the volute is located in the machine case; at least part of the upper part of the volute stretches out of the machine case; the part which stretches out of the machine case is located in the rack. The range hood is simple in structure and reasonable in design; the box body assembly comprising the machine case and the rack is arranged so that thevolute can be arranged in the box body assembly in a semi-embedding manner; on one hand, the flue gas suction and discharging resistance is small and outlet loss of the volute is easy to reduce; noses of a whole machine are optimized; the air inlet resistance is small and inlet gas is sufficient; air quantity and air pressure loss caused by a relatively small box body space also can be avoided and a lampblack suction effect is easy to improve; on the other hand, the volute can be arranged in the box body assembly in a vertical or inclined arrangement manner and reasonable and flexible selection can be carried out according to actual requirement conditions.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to a range hood. Background technique [0002] At present, in the near-suction range hood, the volute is usually inclined so that the distance between the air inlet and the oil fume is shortened to obtain a better smoking effect. Such as 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. [0003] However, i...
