Problems solved by technology

However, when cooking in the kitchen, a variety of harmful gases will be produced. Harmful gases will cause great harm to the human body, such as cancer, etc. The fume gas includes polycyclic aromatic hydrocarbons, and a considerable part of the polycyclic aromatic hydrocarbons has carcinogenic properties. Such as benzo[α]pyrene, when the existing hood is working, there will be a large number of soot particles attached to the hood. Particulate matter adheres to the air outlet of the hood, which affects the overall performance of the hood

Embodiment 1

[0086] A non-pressure loss hood air outlet system with multiple cooking fume treatment, such as Figure 1 to Figure 2 As shown, a hood main body 3 , multiple hood cleaning components 2 and a filter component 100 are provided. The filter component is arranged at the hood air outlet of the hood main body 3 .

[0087] In this embodiment, the multi-hood cleaning assembly 2 is set as a combination of a resonant oil fume filter 21, an oil fume separator 21, and a saponification and decomposition kitchen grease equipment 23.

[0088] Specifically, the resonant oil fume filter 21 is provided with a non-planar filter device 211 for filtering oil fume, and a resonant body 212 with elastic potential energy. The minimum elastic potential energy of the piece>0; one end of the elastic piece is fixed to the fixed frame on the fixed body, the above-mentioned air inlet surface 2122 is at least one of planar or non-planar structures, and any one of the air inlet surfaces 2122 and The other ad...

Embodiment 2

[0117] A non-pressure-loss type hood air outlet system for multiple oil fume treatment, other structures are the same as in Embodiment 1, the difference is that the non-pressure loss type hood air outlet system for multiple oil fume treatment, such as Figure 10 As shown, the filter layer 110 is provided with a gauze 101 .

[0118] Specifically, the relative distance between the gauze 101 and the activated carbon layer 104 along the X-axis direction is B;

[0119] 0mm≤B≤600mm;

[0120] Specifically, the thickness E of gauze 101 纱 ;0.2mm≤E 纱 ≤60mm;

[0121] Specifically, the gauze 101 is set as a single-layer gauze 101

[0122] Specifically, the gauze 101 is provided with ventilation holes, and the ventilation holes are set as any one or more of polygonal ventilation holes, rectangular ventilation holes, circular ventilation holes or oval ventilation holes;

[0123] Specifically, the area of ​​the vent hole is S 孔 ;1mm 2 ≤S 孔 ≤2500mm 2 ;

[0124] By setting the gauze ...

Embodiment 3

[0126] A non-pressure-loss hood air outlet system for multiple oil fume treatment, other structures are the same as those in Embodiment 1 or 2, the difference is that, as Figure 11 As shown, the filter layer 110 is provided with gauze 101 and HEPA net 103;

[0127] Specifically, the gauze 101 and the HEPA net 103 are arranged sequentially along the X-axis of the first plane starting from the origin;

[0128] The gauze 101 and the HEPA net 103 provided through the filter layer 110 can further improve the filtration of harmful substances in the oil fume flow out from both sides.

Abstract

The invention provides a non-pressure-loss type range hood air outlet system for multi-lampblack treatment. The non-pressure-loss type range hood air outlet system for multi-lampblack treatment comprises a range hood body, a multi-lampblack cleaning assembly and a filtering assembly, wherein the filtering assembly is arranged at a range hood air outlet of the range hood body, and the multi-lampblack cleaning assembly is arranged on the range hood body and is arranged to be a combination of at least three of a resonance type lampblack filtering screen, a lampblack separator, a saponification kitchen grease decomposition device, a range hood catalytic degradation device or a range hood spraying device. According to the non-pressure-loss type range hood air outlet system for multi-lampblack treatment, adhesion of lampblack particulate matter to the range hood can be reduced, and the overall performance of the range hood is improved; and the pressure loss to the filtering device of the range hood cannot be caused when the lampblack air flow of the range hood is exhausted, and the non-pressure-loss type range hood air outlet system has the advantages of being simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a non-pressure-loss type hood air outlet system for multiple fumes treatment. Background technique [0002] The range hood is one of the essential electrical appliances in today's family. The range hood is installed above the gas stove in the kitchen, and is used to absorb the oil fumes generated during cooking, so that the oil fumes can be discharged outside, reducing air pollution in the kitchen. However, when cooking in the kitchen, a variety of harmful gases will be produced. Harmful gases will cause great harm to the human body, such as cancer, etc. The fume gas includes polycyclic aromatic hydrocarbons, and a considerable part of the polycyclic aromatic hydrocarbons has carcinogenic properties. Such as benzo[α]pyrene, when the existing hood is working, there will be a large number of soot particles attached to the hood. Particulate matter adheres to the air outlet of ...
