Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0017] Such as figure 1 As shown, it is a schematic diagram of a rectifying plate of a novel central circular hole range hood of the present invention. The new rectifying plate includes the widely used square rectifying plate 1 and the edge 3 of the fume hood; a central round hole 2 (that is, an elliptical opening in the center of the rectifying plate) is set in the center of the square rectifying plate, which directly faces the air duct opening to generate upward exhaust air. The speed is relatively high, and the exhaust air in the center guides most of the rising oil fume from the left or right stove to the center of the fume hood to quickly suck it away; there is a...

Abstract

The invention discloses a novel central circular hole type range hood rectifying plate. Please refer to the schematic diagram of the rectifying plate in the specification. The novel central circular hole type range hood rectifying plate comprises a square rectifying plate body (1), an oil fume hood edge (3) and an annular exhaust area around an oil fume hood opening. A central circular hole (2) isformed in the square rectifying plate body (1). The central circular hole (2) directly faces an air duct opening and generates upper air exhaust and central air exhaust to guide most of the rising oil fume air flow of a left cooking head or a right cooking head to the center of the oil fume hood to be quickly sucked away, and the remaining small amount of oil fume is sucked away from the oil fumehood edge (3) by the uniform wind existing in the annular air exhaust area around the oil fume hood opening (4) and prevented from escaping. Compared with the prior art, by the adoption of the novelcentral circular hole type range hood rectifying plate, the oil fume collecting path of an original rectifying plate can be improved, a better oil fume collecting effect is obtained, and the oil fumecollecting efficiency is improved.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to a household range hood with a rectifying plate. Background technique [0002] Cooking oil fume pollutants will have a serious impact on the kitchen sanitation environment and the physical and mental health of operators. With the improvement of people's living standards, people put forward higher requirements for the air quality of the kitchen. Improving the pollutant collection capacity of range hoods can greatly improve the kitchen sanitation environment, reduce the health threats to kitchen operators, and reduce the pollution of cooking fumes to the atmospheric environment, which is of great significance. [0003] The range hood is composed of a fan and a hood. The structure of the hood affects the distribution of the airflow, thereby affecting the collection effect of the range hood. The distribution of exhaust velocity on the hood surface of ordinary smoke hood is uneven, ...
