Abstract
The invention provides a kitchen lampblack discharge system which has good effect and is convenient to maintain. The kitchen lampblack discharge system comprises a range hood, a check valve, a smoke discharge pipe and a public flue, wherein the smoke discharge pipe is directly and hermetically connected with the public flue, the check valve comprises a vertical pipe which is internally provided with a circular valve plate, the valve plate is rotatably supported on the pipe wall of the vertical pipe by virtue of a transverse shaft which radially penetrates through the valve plate, and the pipe wall of the vertical pipe is provided with a blocking point; when the valve plate is in a horizontal state, the edge of the valve plate is depressed on the blocking point, a weight gain plate is fixed on the valve plate which is located above the blocking point and is close to the blocking point, the upper end and lower end of the vertical pipe are respectively sleeved on the lower end of the smoke discharge pipe and the air outlet of the range hood. In the invention, the check valve is additionally arranged between the air outlet of the range hood and the smoke discharge pipe, and the check valve is connected with the air outlet of the range hood and the smoke discharge pipe in a dismountable way, so as to be convenient to dismount and clean.
Description
Technical field
The present invention relates to the kitchen fume exhaust system.
Background technology
Contain 300 multiple harmful substances in kitchen fume, the function of kitchen fume exhaust system is that kitchen fume is discharged, and its discharging modes are roughly two kinds, and a kind of is directly to enter in the outside atmosphere environment; Another kind is to enter in the common flue that arranges in building.The structure that the below introduces existing kitchen fume exhaust system to common flue discharging is connected the kitchen fume exhaust system and is comprised lampblack absorber, smoke exhaust pipe and the common flue that connects in turn with principle.Smoke exhaust ventilator enters oil smoke suction in the kitchen in common flue.But because many families share same flue, cause other user can enter the kitchen by smoke exhaust pipe to the waste gas of air flue emission, pollute.The main method that addresses this problem at present is to install the check-valves of multi-blade type between smoke exhaust pipe and common flue additional, when smoke exhaust ventilator is worked, the valve block that blows check-valves open enters common flue with oil smoke, when smoke exhaust ventilator was not worked, valve block relied on gravity closing valve and stops oppositely passing through of oil smoke in flue.But this check-valves has following shortcoming: after 1, using a period of time, it is even glutinous that oil smoke easily occurs in valve block, causes check-valves to open and close not smooth, affects exhaust effect; 2. be fixed on the joining place of smoke evacuation tracheae and common flue, not Quick-detachable cleaning because of it.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of kitchen fume exhaust system effective and easy to maintenance.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of kitchen fume exhaust system, comprise lampblack absorber, check-valves, smoke exhaust pipe and common flue, smoke exhaust pipe directly and common flue be tightly connected, check-valves comprises standpipe, standpipe is built-in with a circular valve block, valve block is rotatably supported on the standpipe tube wall by the transverse axis that radially runs through valve block, a gear point is set on the standpipe tube wall, when valve block is in flat condition, be pressed under the edge of valve block on the gear point, be positioned at and fix a weightening finish sheet on gear point top and the valve block near the gear point, the two ends up and down of standpipe respectively with the air outlet socket of smoke exhaust pipe lower end and lampblack absorber.
Above-mentioned kitchen fume exhaust system, standpipe internal diameter-circular valve block diameter=1mm.
Above-mentioned kitchen fume exhaust system, smoke exhaust pipe lower end are coated at the standpipe upper end.
Above-mentioned kitchen fume exhaust system, standpipe lower end are coated at the air outlet of lampblack absorber.
Above-mentioned kitchen fume exhaust system, the weightening finish sheet is fixed on the valve block lower surface, and the state that is pressed under the edge with valve block on the gear point is as the criterion.
Above-mentioned kitchen fume exhaust system, socket place is fastening by anchor ear.
Add loaded check valve between lampblack absorber air outlet and smoke exhaust pipe, check-valves and lampblack absorber air outlet and smoke exhaust pipe removably connect, and are convenient to disassembly, cleaning.When lampblack absorber was not worked, the valve block of check-valves is close port under the effect of self gravitation, avoided the oil smoke in flue oppositely to flow into, and the weightening finish sheet on valve block plays closing assisted effect.During lampblack absorber work, under the effect that air-flow blows to, valve block sways, and opens valve port, and oil smoke is passed through smoothly.The valve block of check-valves is spacing by gear point, guarantees that the contact area of valve block and gear point is little, reduce the glutinous company that contact of valve block and gear point, make the valve block unlatching flexible.
Description of drawings
The present invention is described in more detail below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present invention.
Fig. 2 is part enlarged diagram in Fig. 1.
In figure: 1 lampblack absorber, 2 air outlets, 3 check-valves, 4 smoke exhaust pipes, 5 common flues, 6 transverse axis, 7 valve blocks, 8 standpipes, 9 anchor ears, 10 gear points, 11 weightening finish sheets.
The specific embodiment
as depicted in figs. 1 and 2, a kind of kitchen fume exhaust system, comprise lampblack absorber 1, check-valves 3, smoke exhaust pipe 4 and common flue 5, smoke exhaust pipe directly and common flue be tightly connected, check-valves comprises standpipe 8, standpipe is built-in with a circular valve block 7, valve block is rotatably supported on the standpipe tube wall by the transverse axis 6 that radially runs through valve block, a gear point 10 is set on the standpipe tube wall, when valve block is in flat condition, be pressed under the edge of valve block on the gear point, be positioned at and fix a weightening finish sheet 11 on gear point top and the valve block near the gear point, the two ends up and down of standpipe respectively with air outlet 2 socket of smoke exhaust pipe lower end and lampblack absorber.
In order to guarantee that valve block rotates flexibly under condition, the anti-channeling of reduce oil smoke, standpipe internal diameter-circular valve block diameter=1mm.
Particularly, the standpipe upper end is coated at smoke exhaust pipe lower end or smoke exhaust pipe lower end and is coated at the standpipe upper end.
Particularly, the standpipe lower end air outlet that is coated at the air outlet of lampblack absorber or lampblack absorber is coated at the standpipe lower end.
Particularly, pouring weight is fixed on the valve block lower surface, and the state that is pressed under the edge with valve block on the gear point is as the criterion.
In order to make the socket consolidation, socket place is fastening by anchor ear 9.
