Bidirectional equal-arc curved cooking fume purifying filtering screen and purifying method

Abstract

The invention relates to a bidirectional equal-arc curved cooking fume purifying filtering screen and a purifying method, and belongs to the field of kitchen appliance products. The bidirectional equal-arc curved cooking fume purifying filtering screen comprises a substrate, and is structurally characterized by furthering comprising multiple curved separation and dissipation areas and multiple planar separation and dissipation areas; the curved separation and dissipation areas and the planar separation and dissipation areas are arranged on the substrate, and one planar separation and dissipation area is arranged between every two adjacent curved separation and dissipation areas; curved vent holes and an oil guide stem are arranged on each curved separation and dissipation area; planar vent holes are formed in each planar separation and dissipation area; and the head ends of the curved separation and dissipation areas are located on one side of the substrate, and the tail ends of the curved separation and dissipation areas are located on the other side of the substrate. According to the bidirectional equal-arc curved cooking fume purifying filtering screen, the equal-arc curved features are fully utilized, airflow turbulent flow can be effectively motivated, internal dissipation is improved, and therefore the fat separation degree is improved; and the bidirectional equal-arc curved cooking fume purifying filtering screen is novel in form, accords with human factor engineering, and is convenient for a user to scrub and clean.

Description

technical field [0001] The invention relates to a two-way equal-arc surface oil fume purification filter screen and a purification method, belonging to the field of kitchen electrical appliances. Background technique [0002] At present, the commonly used filter screens on the market are mostly small-hole dense screens and single-layer or double-layer filter screens with long air holes; the small-hole dense screens are difficult to process because the opening size is only about 1.5 mm, and they are difficult to process during use. It is easy to block in the center, and frequent disassembly and cleaning will easily lead to damage to parts; the long air holes are easy to scrub, but the grease separation degree of the single-layer mesh is relatively low. As a result, the cost increases, the weight of the whole machine increases, and due to the difference in the design of the double-layer net, there are also problems such as increased difficulty in disassembly and difficult scru...

Problems solved by technology

[0002] At present, the commonly used filter screens on the market are mostly small-hole dense screens and single-layer or double-layer filter screens with long air holes; the small-hole dense screens are difficult to process because the opening size is only about 1.5 mm, and the process of use It is easy to block in the center, and frequent disassembly and cleaning will easily lead to damage to parts; the long air hole is easy to scrub, but the grease separation degree of the single-layer mesh is relatively low. As a result, the cost increases, the weight of the whole machine increases, and due to the different design of the double-layer net, there are also problems such as increased difficulty in disassembly and difficult scrubbing of the inner net.

[0003] In view of this, in the patent document with application number 201210355913.6, the concave-convex structure filter screen device of the range hood is disclosed. At present, the common filter screens in the market are mostly characterized by plane or conical arc surface. Frontal interception of condensation, not sufficient to stimulate airflow disturbance turbulence and internal dissipation
