Have the advantages that in coal gas, natural gas low in cost, be widely used in kitchen, however, coal gas, natural gas are easy leakage, danger
The life security of evil user.Kitchen ventilator is a kind of kitchen appliance for purifying kitchen environment, is mounted in kitchen, above cooking stove,
The oil smoke being harmful to the human body generated in the waste and cooking process of cooking stove burning can be taken away rapidly, discharge is outdoor, kitchen ventilator
Pollution can be reduced, air is purified, and has gas defence, explosion-proof safety guarantee effect, the waste that cooking stove can be burnt and culinary art
The oil smoke being harmful to the human body generated in the process is extracted into outdoor, reduces pollution, purifies the air of a room, with progress of the epoch, oily
Smoke machine is gradually changed from traditional only structure with simple function becomes the structure for having various modes function now, people couple
It needs to learn how practice uses in the kitchen ventilator of new construction, this is inconvenient for the elderly of decrease of memory
Thing, in order to solve this problem, people are proposed the kitchen ventilator that can be remotely controlled, but also can not be good
Reply actual needs, and can not be adjusted according to the actual situation, in addition, the long-range control is only merely long-range control, not
It can teach how user operates, modern younger generation are busy with one's work, it is impossible to carry out for a long time to kitchen ventilator long-range
Control, however environment needed for different dish is also different in cooking process, it can be seen that, there is designs for existing kitchen ventilator not
The problem of enough hommizations is forgotten to close valve or pipeline leakage, is easy to bring seriously to user security once user when cooking
Injury, user experience effect is poor.
Currently, the function of existing kitchen ventilator is relatively simple, it can not detect whether kitchen coal gas, natural gas leaking etc. occurs
It is dangerous.Also, existing kitchen ventilator needs the participation of cooker also to carry out opening or closing kitchen ventilator, it is contemplated that kitchen kitchen range
In operation, it can be stained with greasy dirt on hand, key can be made dirty when operating kitchen ventilator, or will appear the phenomenon that being nervously fumbled,
It has no time to attend to operate kitchen ventilator, and kitchen ventilator culinary art terminates user and closes kitchen ventilator, since culinary art terminates oil smoke not by abundant outlet,
Therefore the emptying that kitchen ventilator is unfavorable for kitchen fume is closed immediately, although existing kitchen ventilator has the function of time-delay closing, it prolongs
When close pattern under power of motor and operating duration all be setting, can not voluntarily be adjusted according to kitchen space, still not
Conducive to the emptying of kitchen fume.The design passes through the participation for reducing cooker mainly to make kitchen ventilator more intelligent.
