Straight-draught range hood with double-air-inlet blower

Abstract

A straight-draught range hood with a double-air-inlet blower belongs to the field of range hoods and overcomes the shortcomings that a conventional range hood is poor in suction and exhaust effects and narrow in use space. The straight-draught range hood comprises a case consisting of a transverse case body and a vertical case body which are connected with each other, wherein a first vertical air duct is formed in the interior hollow part of the vertical case body; a first smoke inlet and a second smoke inlet which are communicated with the first vertical air duct are respectively formed in the upper part and the lower part of the vertical case body; an exhaust fume collecting hood is arranged on the case; an oil cup is arranged at the lower part of the case; the blower is arranged in the exhaust fume collecting hood; the air outlet of the blower is formed in the upper part of the exhaust fume collecting hood and communicated with the outside; the included angle beta between the transverse case body and the inner side surface of the vertical case body is smaller than 135 degrees and larger than 90 degrees; an air inlet is formed in each of two sides of the blower; the first vertical air duct is communicated with one of the air inlets of the blower; the transverse case body is provided with a third smoke inlet penetrating the transverse case body; and the third smoke inlet is communicated with the other air inlet of the blower through a second vertical air duct in the exhaust fume collecting hood. The straight-draught range hood is large in use space, good in suction and exhaust effects and excellent in energy-saving effect.

Description

technical field [0001] The invention belongs to the field of range hoods, and in particular relates to a fan double-inlet direct suction type range hood. Background technique [0002] At present, range hoods are mainly divided into top suction type and side suction type range hoods with two types of air intake. The cooking space of the top-suction range hood is small, and there is a sense of oppression when cooking, and sometimes it is accidentally touched, and because of a certain height, the smoking effect is not ideal. The appearance of the side-suction range hood has greatly improved the smoking effect, but the shape of the side-suction range hood is relatively bulky, and it is not so coordinated with the kitchen, and the range hood extends from the wall as a whole, often making the two Layered steamers and some bulky cooking utensils cannot be used, causing great inconvenience to consumers, especially consumers in the north. In addition, because the side suction hoo...

AI Technical Summary

Problems solved by technology

The cooking space of the top-suction range hood is small, and there is a sense of oppression when cooking, and sometimes they touch each other accidentally, and because of a certain height, the smoking effect is not ideal

The appearance of the side-suction range hood has greatly improved the smoking effect, but the shape of the side-suction range hood is relatively bulky, and it is not so coordinated with the kitchen, and the range hood extends from the wall as a whole, often making the two Layered steamers and some large-volume cooking tools cannot be used, causing great inconvenience to consumers, especially those in the north

In addition, because the side suction hood is very close to the cooking area, excessive suction is likely to cause local oxygen supply to be thin, which often leads to insufficient gas combustion, which increases the consumption of gas and is not energy-saving enough.

[0003] At present, there is a range hood with a combination of top suction and side suction on the market. The air duct is equipped with a smoke inlet, which is equivalent to side suction; the horizontal air duct is also equipped with a smoke inlet, which is equivalent to top suction; however, the distance between the smoke inlet of the horizontal air duct and the vertical air duct is long, and the vertical air duct The negative pressure formed by the horizontal air duct makes the smoking effect of the horizontal air duct not good, so the effect of horizontal and vertical suction and discharge cannot be achieved
