Efficient smoke exhaust and matched hearth thereof

Abstract

The invention provides an efficient smoke exhaust and a matched hearth thereof. The efficient smoke exhaust is composed an upper part and a lower part, the upper part is the smoke exhaust, and the lower part is the fuel gas hearth. A semi-closed U-shaped gas pipe is arranged on the lower portion of a smoke exhaust shell, and a flat-long-strip-shaped air outlet is formed in the position below the gas pipe. A semi-closed U-shaped gas pipe is arranged on the position above the hearth as well, and a flat-long-strip-shaped air outlet is formed in the position above the corresponding gas pipe. In working, an exhaust fan is started, negative pressure is formed in a gas suction cavity of the smoke exhaust, screwing up airflow is generated, and thus oil smoke generated by cooking is exhausted to the outer side of a kitchen through an exhaust pipe. Meanwhile, the smoke exhaust and an air blower of the hearth are started, an air curtain is formed in the position below the smoke exhaust shell and above the hearth, the oil smoke generated during cooking is closed in a certain space and completely removed in a sucked mode, and thus oil smoke sucking removal efficiency is improved. According to the efficient smoke exhaust and the matched hearth thereof, the oil smoke can be effectively prevented from diffusing, and indoor air keeps fresh and cool; and meanwhile, working efficiency of the smoke exhaust can further being improved, and energy sources are saved.

Description

technical field [0001] The invention relates to kitchen utensils, in particular to a high-efficiency range hood and its matching stove. Background technique [0002] The working principle of the range hood is that through the fan installed inside, the high-speed centrifugal rotation after power-on generates a powerful swirling airflow, and the oil fume generated during cooking is discharged to the outside through the air outlet. [0003] At present, most range hoods on the market are top-suction type, that is, the entire range hood is located directly above the stove. The centrifugal fan is installed in the suction chamber of the range hood. When working, the centrifugal fan rotates at high speed to generate a certain negative pressure, which then generates a swirling airflow, and uses the natural rising characteristics of the cooking fume to reduce the harmful cooking fume and combustion. The exhaust gas produced is sucked. For ease of operation, there is usually a height...
