Today, range hoods have entered thousands of homes and become indispensable kitchen appliances. In this way, although the problem of oil fume has been solved, new problems have emerged again – often encountering the problem of low oil absorption of range hoods. Let’s take a closer look. First of all, we learned about the two ways of sucking oil from the range hood, and then analyzed the reasons for the small suction of the range hood:
Two ways to absorb oil from a hood
1. Deep cover type: The deep cover type includes deep type or deep cabinet type. These two types of range hoods are equipped with deeper ( larger volume ) hoods. When the fan is placed at high speed, the upper part of the hood is formed. The negative pressure zone is used to accommodate the fumes that are too late to be pumped away, which acts as a buffer to avoid the spread of a large amount of soot spillage;
2 , side suction type: refers to the air inlet of the wind cabinet and the wind wheel in the vertical plane, the air outlet is on the horizontal plane (top), the side suction is the use of the inner cavity to form a huge smoke buffer, resulting A certain wind pressure, the pressure of exhausting smoke is large, the exhausting speed is fast and thorough, and the oil path is well controlled. Side suction hoods are mostly meant to be mounted on the side of the wind wheel or at the center of the angle. From the appearance, you can directly see that the air inlet is on the side. The suction of the side suction is better than that of the direct suction, but since the wind wheel is mounted on the side angle, it is more troublesome to clean.Analysis of small suction force of range hood
1. The distance between the range hood and the cooker is too high:
Simple solution: readjust the height
2 , the exhaust pipe is too long, too many turns:
Simple solution: install the exhaust pipe correctly according to the instructions
3 , the direction of the outlet is not properly selected or blocked by obstacles :
Simple solution: change position and clear obstacles
4 , the kitchen air convection is too large or the seal is too strict:
Simple solution: reduce air convection or moderate opening windows
5 , the exhaust pipe interface is seriously leaking:
Simple solution: sealed
The main factors affecting the suction force of the range hood are:
1 , the amount of exhaust air;
2 , the distance between the air inlet of the range hood and the cooker;
3 , the distance of the range hood from the flue (that is, the length of the pipe).
The amount of exhaust air is generally calculated in terms of how many cubic meters per minute. Each model of the range hood will be marked. The current high market is 18 cubic meters / minute.
The side suction hood is closer to the cooker, so it is generally better than the European smoking. However, the European straight plate is installed directly above the cooker. According to the principle of convection, the smoking ability is not bad.
The location of the hood design can't be too far from the flue, otherwise the smoking effect will be greatly reduced, and even the soot can be reversed.
In fact, the suction of the hood is not as good as possible. The hood with large suction power is generally powerful, and the radiation, energy consumption and noise are relatively increased. In general, the size of the kitchen is no more than 15 square meters, and a 17- m3 / min hood can fully meet the daily exhaust demand. The 17- m3 / min hood can change the entire kitchen in three minutes. gas.
