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 polycyclic aromatic hydrocarbons has carcinogenic properties. properties, such as benzo[α]pyrene, when the air outlet component in the hood exhausts the gas, the gas at the air outlet will cause pressure on the air outlet of the hood due to the air flow, which in turn will cause damage to the air outlet of the hood damage
[0003] Moreover, the exhaust system of the existing hood can only directly discharge the fume gas to the outside. When the environment in which the range hood is used is in a relatively sealed state, the fume gas can only be discharged to the outside through a special long fume exhaust pipe, such as This situation exists in the catering areas of many large shopping malls, which greatly wastes manpower, material resources and financial resources.

Embodiment 1

[0050] A circulating smoke machine filter screen for indoor and outdoor inner space environment, such as Figure 1 to Figure 2 As shown, a filter assembly 100 is provided, and the filter assembly 100 is provided at the air outlet of the hood.

[0051] Specifically, take the outer end surface of the air outlet of the hood as the first plane, establish a cross coordinate system with the center point of the first plane as the origin, and take the horizontal direction of the first plane to the right as the positive direction of the X-axis, so as to point toward the outlet of the hood. The direction that the tuyere passes through the origin and is perpendicular to the first plane is the negative direction of the Y axis;

[0052] Specifically, starting from the origin, the filter assembly 100 is sequentially fixed with a filter layer, a UV lamp 102, an activated carbon layer 104, and a housing 105 along the X-axis of the first plane;

[0053] The main function of activated carbon i...

Embodiment 2

[0077] A circulating hood filter for indoor and outdoor environments, other structures are the same as in Embodiment 1, the difference is that the circulating hood filter for indoor and outdoor environments, such as image 3 As shown, the filter layer is provided with gauze 101 and HEPA net 103;

[0078] Specifically, the gauze 101 and the HEPA net 103 are arranged sequentially along the X-axis of the first plane starting from the origin;

[0079] Define the surface area of ​​the HEPA net 103 as S HEPA网 , 500mm 2 ≤S HEPA网 ≤678500mm 2 ;

[0080] Define the surface area of ​​gauze 101 as S 纱网 , 500mm 2 ≤S 纱网 ≤678500mm 2 ;

[0081] The surface area of ​​the filter cotton 106 is defined as S 棉 , 500mm 2 ≤S 棉 ≤678500mm 2 .

[0082] Under a specific Q, the flow rate obtained by the design of the filter assembly has the following relationship, and Q is the pressure of the exhaust hood wind force of the range hood.

[0083] (a) The flow rate without entering the activat...

Embodiment 3

[0094] A circulating hood filter for indoor and outdoor environments, the other structures are the same as in Embodiment 1 or 2, the difference is that the HEPA net 103 and the gauze 101 start from the origin and move along the X axis of the first plane. The axes are set sequentially.

[0095] By adjusting the position of the HEPA net and gauze, the harmful substances and solid particles in the airflow exhausted by the hood can be isolated to the greatest extent, and the pollution to the system can be reduced.

Abstract

The invention provides a circulating type kitchen ventilator filter screen used in indoor and outdoor space environments. The circulating type kitchen ventilator filter screen used in the indoor and outdoor space environments is provided with a filter assembly, the filter assembly is assembled to an air outlet of a kitchen ventilator, and the filter assembly is arranged at the air outlet of the kitchen ventilator. The filter assembly is provided with a filter layer, a UV lamp, filter cotton, a first baffle, an activated carbon layer and a shell; the filter layer is provided with a gauze element, or the filter layer is provided with the gauze element and an HEPA net. By means of the circulating type kitchen ventilator filter screen, gas discharged from the kitchen ventilator can be fully filtered, and the gas discharged from the kitchen ventilator is completely clean; the circulating type kitchen ventilator filter screen has the advantages of being simple in structure and convenient touse, and a lot of manpower, material resources and financial resources are saved.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a circulating hood filter used for indoor and outdoor environments. 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. properties, such as benzo[α]pyrene, when the air outlet component in the hood exhausts the gas, the gas at the air outlet will cause pressure on the air outlet of the hood due to the air ...
