Embodiment Construction
[0012] The implementation of the power on-off system for range hoods of the present invention will be described in detail below.
[0013] Many users turn off the range hood after only turning it on for a few minutes when cooking, which cannot play its role. The correct way to use it is to turn it on as soon as the cooking starts, and then turn it off after 5-6 minutes after the whole cooking is over. . Here, because natural gas or liquefied petroleum gas, when the range hood is disabled, the nitrogen compound will exceed the standard by 5 times as long as it is burned for a few minutes, and the carbon monoxide gas can exceed 65 times the standard. The range hood should work all the way, instead of turning on and off from time to time. As for the reason why it is still necessary to work for a few minutes after the cooking is over, it is to discharge the harmful gas remaining in the kitchen to the greatest extent, so as not to keep it in the kitchen, so as to prevent harm to hu...

The invention relates to a range hood power on / off system. The range hood power on / off system comprises a driving assembly, a power supply assembly and a power supply switcher, wherein the driving assembly comprises a volute, a motor, an exhaust fume collecting hood, an air guide ring, locking nuts and a draught fan cover; the volute is arranged close to the motor; the power supply assembly comprises a base, an electric control box, a commercial power connection terminal and a voltage stabilizing element; the commercial power connection terminal is connected into the electric control box; theair guide ring is arranged on the motor through the locking nuts; the draught fan cover is arranged on one side of the air guide ring; the base is arranged below the electric control box; the voltagestabilizing element is arranged in the electric control box, and is connected with the commercial power connection terminal; the power supply switcher is positioned in the electric control box, is connected with the commercial power connection terminal, and is used for cutting off the power supply of the commercial power connection terminal to the driving assembly when a switch-off state signal isreceived, and for recovering the power supply of the commercial power connection terminal to the driving assembly when an ignition state signal is received. By adopting the range hood power on / off system, an electronic auxiliary function of a range hood is completed.
Description
technical field [0001] The invention relates to the field of range hoods, in particular to a power switching system for range hoods. Background technique [0002] Range hoods use oil filter screens in terms of oil fume filtration. There are one, two or more layers, and the filter holes are square, rhombus, round, etc. The purpose is to block the oil fume through the filter, but from the use of so many years, the effect of this solution is very poor. Even when the filter screen is as small as 0.01 square centimeters, 37% of the oil fumes cannot be blocked. The filter mesh holes of most hoods on the market are about 0.04 square centimeters, so it is almost directly discharged, and the result is pollution of the inner wall of the hood. A large amount of uneven oil accumulation is caused in the impeller of the fan, and the dynamic balance of the fan rotation is lost, so the suction effect is naturally getting worse, and the mechanical noise is getting louder. In short, without...
