Abstract

The invention relates to an automatic air supply device of an extractor hood in closed or semi-closed space, in particular to an automatic air supply technology of the extractor hood. A device which does not change the original function or appearance of an existing extractor hood and does not increase any power consumption is arranged in the original extractor hood, and the situation that lampblack suction of the existing extractor hood in the closed or semi-closed space is noneffective or basically noneffective is thoroughly solved. According to the content of the automatic air supply technology, a pipe leading to the outside is used for supplying air to a closed kitchen. According to the technical scheme for solving the technical problem, an air inlet pipe is added in an air pipe of the extractor hood and enters the position below the indoor extractor hood for air output; an air inlet is provided with an air inlet check valve, and once the kitchen is sealed, the air inlet check valve can be sucked by wind power due to the suction force of the extractor hood; and automatic air supply is achieved below the extractor hood.

Description

Range hood automatic ventilating technology

The present utility model patent is range hood automatic air in a kind of airtight or semi-enclosed space.

Be one is not changed existing lampblack absorber original function, original outward appearance, the device not increasing any power consumption is arranged in original range hood.The existing range hood of thorough solution, the situation that fume-exhausting is invalid or substantially invalid in airtight or semi-enclosed space.

House now more and more seals, and particularly in air-polluting situation, people select to close door and window, and the kitchen fume crisis brought thus just all the more seriously.Present lampblack absorber all adopts super large suction without exception, high quiet.I examined, and in airtight kitchen, as long as one opens lampblack absorber, backstairs is not locked and will be opened by suction.And be exactly how to strengthen fume-exhausting power again in the kitchen of sealing, be also that oil smoke fills the air, there is no effect.There is idea thus in person.Lead to the piping outside the house via one, blown in airtight kitchen.Not only significantly can reduce the power consumption of motor, with the convection current of air, oil smoke can also be taken away as early as possible.

The method of main realization is as follows:

Lampblack absorber can increase an air intake airduct (T-2) in wind pipe.Via in lampblack absorber down (T-4) to lampblack absorber lowest part air-out (T-5).Other one naturally droops (T-1) { air inlet has band air intake check-valves, ensures not to be opened in the packing less situation in indoor } in outdoor or vent stack.Indoor (T-3) are entered via original discharge pipe.

Once kitchen sealing, because the air draught air intake check-valves of lampblack absorber will be picked up by wind-force.Automatic ventilating below lampblack absorber, air intake directly siphons away from lampblack absorber wall, thus forms certain negative pressuren zone, and oil smoke is inhaled toward lampblack absorber wall, thus reduces the diffusion of oil smoke, siphons away oil smoke quickly.

Be exactly solve the ability of lampblack absorber at the fume-exhausting in sealing place completely like this when not increasing a lot of cost.

accompanying drawing illustrates:

Fig. 1 is (T-1) beginning outdoor of this range hood automatic ventilating technology, indoor (T-3) are entered, from (T-4) in oil smoke body down to the lampblack absorber side schematic view that the most beneath (T-5) blows via former lampblack absorber discharge pipe (T-2).

Fig. 2 is (T-1) beginning outdoor of this range hood automatic ventilating technology, indoor (T-3) are entered, from (T-4) in oil smoke body down to the lampblack absorber front schematic view that the most beneath (T-5) blows via former lampblack absorber discharge pipe (T-2).

Claims

1. one kind increases the technology of an admission line in original smoke exhaust pipe of range hood.

2. in former lampblack absorber discharge pipe, increase an air intake airduct.

3. via down arriving the air-out of lampblack absorber lowest part in lampblack absorber.

4. other one naturally droops in outdoor or vent stack.

5. enter indoor lampblack absorber via original lampblack absorber discharge pipe.

6. as follows according to this automatic ventilating system features of claim:

The indoor sealing or when having certain sealing when lampblack absorber runs, this system can be supplemented room air automatically via blast pipe (T-1) (T-2) (T-3) (T-4) (T-5), reduce the loss of lampblack absorber, and oil smoke can be siphoned away quickly.

7. outdoor air inlet (T-1) has an air intake check-valves, and under indoor do not have Packed situation, this system can not carry out supplementing of room air.

8. this system is without any electric power or Mechanical Driven, does not produce any resource consumption.
