Description

Technical Field

[0001] The present application relates to the technical field related to kitchen appliances, and in particular to a range hood. Background Art

[0002] The existing range hood is a kitchen appliance for purifying the kitchen environment. It is installed above the kitchen stove and can quickly extract the waste from the stove combustion and the oil smoke generated during the cooking process that is harmful to the human body and discharge it to the outside. At the same time, the oil smoke is condensed and collected to reduce pollution, purify the air, and has the safety protection function of anti-toxicity and explosion-proof. The existing range hood includes a smoke inlet, an air outlet, and an air duct connecting the two air outlets. A fan is provided on the air duct. The air duct connects the kitchen and the smoke pipe, and the smoke pipe connects to the outside to suck the kitchen oil smoke to the outside. Since the oil smoke needs to stay inside the range hood to fully purify the oil smoke, the exhaust path of the oil smoke is tortuous, so that the oil smoke stays inside the range hood as long as possible, so that the exhaust gas is purified more fully, thereby making this method slow in oil smoke treatment speed and exhaust efficiency.

Since the purification channel is composed of the vertically arranged air inlet 11, the purification chamber 12 and the air outlet 13, the oil smoke enters from the air inlet 11, is purified by the purification chamber 12, and then enters the fan 2 through the air outlet 13. The oil smoke has a vertical direction and the shortest path during the purification process, which is conducive to increasing the emission speed of the oil smoke, thereby improving the emission efficiency of the purified gas. In addition, the vertically arranged purification channel can provide a relatively straight exhaust path without too many bends, which helps to reduce the resistance and energy consumption during the exhaust process. At the same time, the vertically arranged purification channel can reduce the space occupied by the range hood in the horizontal direction of the kitchen, which is an advantage for places where the kitchen space is relatively compact.

[0039] Preferably, the air inlet 11, the purification chamber 12 and the air outlet 13 are integrally arranged to avoid gaps between the air inlet 11 and the purification chamber 12 and between the air outlet 13 and the purification chamber 12, thereby preventing oil smoke from leaking after entering the purification channel.

Moreover, there is no need to set a smoke pipe, so that the air can circulate in the kitchen, which is beneficial to improving the flow efficiency of the air in the kitchen, thereby benefiting the cooling of the kitchen. Preferably, a plurality of through holes 14 are evenly provided around the top side wall of the body 1, including the front side, the rear side, the left side and the right side of the top side wall of the body 1, so that the smoke discharged from the fan 2 can be evenly discharged from all sides, thereby more effectively reducing wind resistance and improving the smoke discharge efficiency.

The outlets of the fan 2 are provided in multiple ways, so that the smoke entering the fan 2 can be discharged from the outlets of the multiple fans 2, thereby reducing wind resistance and reducing the energy consumption of the fan 2. Moreover, the smoke discharged from the outlets of the multiple fans 2 is discharged to the outside of the body 1 through the through hole 14, and there is no need to set a smoke pipe, so that the air can circulate in the kitchen, which is beneficial to improving the flow efficiency of the air in the kitchen, thereby benefiting the cooling of the kitchen. Preferably, multiple through holes 14 are evenly provided around the top side wall of the body 1, including the front side, rear side, left side and right side of the top side wall of the body 1, so that the smoke discharged from the fan 2 can be evenly discharged from all sides, thereby more effectively reducing wind resistance and improving the exhaust efficiency of smoke.
