A high-efficiency exhaust system for household upper-mounted and upper-discharge range hoods

Abstract

The invention relates to a high-efficiency household upper-mounted upwards-exhaust type range hood exhaust system. The bottom of a range hood (1) is provided with a smoke suction port I (2) and a smoke suction port II (3), a fan M1 (4) is arranged in the smoke suction port I, and a fan M2 (5) is arranged in the smoke suction port II; a smoke outlet (6) is formed in the top of the range hood (1), afan M3 (7) is installed in a smoke outlet pipeline of the smoke outlet, a cavity among the smoke outlet, the smoke suction opening I and the smoke suction opening II is a smoke collecting cavity (8),a gas sensor BA is arranged in the smoke collecting cavity, and a control circuit for controlling the fan M1, the fan M2 and the fan M3 to work is further installed in the range hood; and the gas sensor BA feeds a signal of gas concentration of lampblack in the smoke collecting cavity back to the control circuit. The exhaust system has the beneficial effects that the structure is simple, and thelampblack can be quickly discharged on the premise of reducing energy consumption and noise.

Description

technical field [0001] The invention relates to a range hood exhaust system, in particular to a high-efficiency household top-mounted and top-drain type range hood exhaust system, which belongs to the technical field of range hood smoke exhaust. Background technique [0002] Because cooking can produce a large amount of lampblack, range hood is widely used. [0003] According to different structures, range hoods can be divided into top-mounted and top-drain type and bottom-mounted and bottom-drain type range hoods. Because most of the range hoods with bottom-mounted and bottom-drain structure are composite all-in-one machines, the smoke exhaust effect is better. , but the price is relatively expensive, and ordinary people are discouraged. [0004] Therefore, the general household range hoods mostly use the top-mounted and top-row range hoods, and the top-mounted and top-row range hoods mostly use a high-power single motor. The oil fume outside the air duct spreads to the l...

Problems solved by technology

[0003] According to different structures, range hoods can be divided into top-mounted and top-drain type and bottom-mounted and bottom-drain type range hoods. Because most of the range hoods with bottom-mounted and bottom-drain structure are composite all-in-one machines, the smoke exhaust effect is better. , but the price is relatively expensive, and ordinary people are discouraged

[0004] Therefore, the general household range hoods mostly use the top-mounted and top-row range hoods, and the top-mounted and top-row range hoods mostly use a high-power single motor. The oil fume outside the air duct spreads to the low-temperature area outside the air duct, and the oil fume diffuses in the air, and the effect of oil fume extraction is not good
