Problems solved by technology

[0005] The above-mentioned patent application provides a range hood using electrostatic adsorption to obtain better adsorption and cleaning effect. However, since the oil fume does not undergo further treatment of oil fume particles before entering the high-voltage electrostatic field, the smoke in the smoke Therefore, the high-voltage electrostatic field will absorb a large number of oil fume particles in a short period of time. If it is not removed in time, it will seriously affect the future electrostatic adsorption effect, and even aggravate the oil fume emitted by the range hood. particle content
In this way, not only the fume purification effect is not ideal, but also cause troubles to users

Embodiment 1

[0072] like figure 1 , figure 2 and image 3As shown, the difference between this embodiment and the above-mentioned specific implementation is only that: the range hood of this embodiment further includes an oil net condensation adsorption device 100 . The oil net condensation adsorption device 100 of this embodiment is installed on the smoke collection chamber 600, the main box body 500 is arranged on the upper part of the smoke collection chamber 600, and the dynamic centrifugal adsorption device 200, the air duct condensation adsorption device 300 and the electrostatic adsorption device 400 are installed on the main box 500.

[0073] The oil screen condensation adsorption device 100 of this embodiment includes an inverted conical outer oil screen 101 and an inner oil screen attached to the outer oil screen 101. The outer oil screen 101 has a grid-like structure, and the inner oil screen has a wave-shaped diamond-shaped hole structure.

[0074] The inverted cone-shaped ...

Embodiment 2

[0079] In this embodiment, the electrostatic adsorption device is replaced by a catalyst substance as a form of adsorption, which can also realize the adsorption of the oil fume particles remaining at the air outlet.

[0080] The advantage of this embodiment is that it is easier to realize the adsorption of the catalyst substance, and it is also more energy-saving and environment-friendly.

Abstract

The invention provides a range hood provided with a multi-layer purifying and adsorbing device. The range hood comprises a dynamic centrifugal adsorbing device, an air channel condensing and adsorbing device and an electrostatic adsorbing device which are sequentially arranged from a cooking fume suction direction to a cooking fume exhaust direction; the dynamic centrifugal adsorbing device comprises a rotatable centrifugal mesh disc; the electrostatic adsorbing device can form a high-voltage electric field for adsorbing cooking fume particles; and the air channel condensing and adsorbing device is used for conveying cooking fume and condensing and adsorbing the cooking fume in a conveying process. According to the range hood provided by the invention, at least three layers of adsorbing devices are arranged for adsorbing and purifying the cooking fume particles, therefore the indexes such as air volume of the range hood reach the standards, the PM2.5 emission index is also reduced more effectively, and the overall environment of a kitchen and air is improved.

Description

technical field [0001] The invention relates to the technical field of purifying and absorbing oil fume by range hoods, in particular to a range hood with multi-layer purification and adsorption devices. Background technique [0002] With the improvement of material living standards, people have higher and higher requirements for the kitchen environment, and the practicability and frequency of use of range hoods are also getting higher and higher. However, while people are enjoying the good life brought by high technology, they inadvertently have a serious impact on the surrounding environment. Today, due to the continuous emission of soot and dust, the air quality has dropped sharply, and the PM2.5 and PM10 indexes have risen sharply. Aiming at the environmental pollution problems caused by the exhaust of range hoods, range hoods with unique functions such as oil-gas separation, clean gas discharge, environmental protection and energy saving are often created by adding pur...
