Problems solved by technology

The suction of this type of range hood is not high, and some of the fume gas will always escape, causing harm to the operator.
The filter screen only blocks part of the oil. As a result, the inner wall of the range hood is polluted, causing a large amount of uneven oil accumulation on the fan impeller, the fan rotation is out of balance, the suction efficiency is reduced, and the mechanical noise is getting louder. Therefore, it is necessary to perform laborious and time-consuming cleaning on a regular basis. Large power consumption, generally above 200W
[0004] Before this invention, there was a Chinese patent of "tornado generating device and range hood equipped with the tornado generating device", the application number is 201110253683.8, but it is an enhanced range hood for the current fan range hood, an accessory part, Not a real artificial tornado range hood

Embodiment 1

[0038] Embodiment 1: as Figure 1 to Figure 8 shown. Press the electrical switch of the artificial tornado range hood, the supercharging turbine (6) starts, and the gas at both ends of the front of the smoking machine passes through the plug-in type oil filter (5) and the detachable filter screen (17) of the turbine air inlet. Filtered, clean air is sucked into the supercharger turbine (6), after boosting, the air is input to the regulator cylinder (4), and after the pressure regulation of the regulator cylinder (4), the air flow is uniformly and stably input to each low In the sonic airfoil gas blowing column (14), the air passes through the expansion in the wing cavity, and the airflow is ejected from the vertical blowing slit (δ) of the airfoil gas, and is accelerated by the arc-shaped convex airfoil, forming several In the same rotation direction, the air curtains surround the inscribed circle concentric with the smoke chamber (3), the air curtains spray from the window o...

Embodiment 2

[0039] Example 2, such as Figure 9 Shown, be the embodiment of another kind of man-made tornado generating device of the present invention, its feature is to blow out post (25) with standpipe type vertical long slit guiding gas blowing out post (25) to replace the low-speed airfoil type gas blowing out post (14) of embodiment 1 ), the whole implementation process is the same as in Example 1.

Abstract

The invention discloses an artificial tornado range hood. The artificial tornado range hood comprises an artificial tornado generation device, a commutator combination for converting concentrated sucking force of artificial tornado to an ultrastrong and ultra-wide negative pressure chamber, a lampblack sucking channel and a lampblack separation module consisting of a lampblack collecting cover, an oil filter plate and an annular channel secondary oil filter screen, a device for re-sucking escaped lampblack and a straight lampblack discharge channel; and all the components form a complete system. The artificial tornado range hood can keep a stable, ultrastrong and efficient working state for a long time, is low in power consumption, saves time and labor during cleaning, is lower in noise, and is a novel range hood different from a centrifugal wind wheel range hood.

Description

1. Technical field [0001] The invention relates to a kitchen range hood, in particular to an artificial tornado range hood. 2. Background technology [0002] Kitchen fume contains a variety of harmful substances, which can lead to lung cancer, pneumonia and other respiratory diseases. The World Health Organization and the United Nations Development Program issued a statement saying: Kitchen smoke has become a major disaster that threatens human health, and many people have lost their lives because of it. The dietary structure of the Chinese is different from that of the Westerners. Frying, frying, cooking, and deep-frying account for a large proportion of food processing, so the oily smoke is greater and the health hazards to the people are more serious. [0003] There are many range hood styles on the market, but all are centrifugal wind turbines. The suction of this type of range hood is not high, and a part of the fume gas always escapes, causing harm to the operator. ...
