Abstract

The utility model relates to a cooking fume flue shutter which is a utensil which is arranged on a cooking fume removing flue and prevents foreign odor in the fume removing flue from entering a room. An outer shell of the utility model is divided into an upper shell and a lower shell. One end of the lower shell forms a round tube shape to be inserted in a public fume removing flue. An isolation valve sheet is arranged between the upper shell and the lower shell. The lower part of the valve sheet is provided with a handle in an extending mode. When the handle is wrenched, the isolation valve sheet can rotate around a rotating shaft. The utility model has the advantages of simple structure, low cost, and convenient usage. When a cooking fume exhauster is not used, the utility model can prevent foreign odor in the fume removing flue from entering a room to pollute air.

Description

Kitchen oil flue isolating valve

The utility model relates to and a kind ofly is installed on the exhaust stack of kitchen, prevents that peculiar smell imports indoor apparatus in the exhaust stack, is a kind of kitchen oil flue isolating valve specifically.

In recent years in the multi-storey residential buildings that built up, be provided with public exhaust stack, the each household kitchen is provided with a socket, oil supply and discharge cigarette machine smoke exhaust pipe inserts wherein, because the non-return valve on the smoke exhaust does not have buffer action, it is indoor to cause various smells in the exhaust stack gently often to import into, pollutes indoor air, makes the people feel to feel bad.

The utility model purpose is to overcome the shortcoming in the above-mentioned technology, proposes a kind of kitchen oil flue isolating valve, is installed on the mist extractor road junction, and the corrugated tube of smoke exhaust is inserted wherein, when mist extractor not, exhaust stack is closed, prevent that peculiar smell from importing into, when mist extractor, can open, oil smoke is drained.

The utility model purpose is realized by following technical scheme: this kitchen oil flue isolating valve, include shell, it is characterized in that shell is divided into upper casing and lower casing two parts, lower casing one end is round tube shape, insert in the public exhaust stack, the isolation valve block is housed between upper casing and the lower casing, handle is extended in the valve block below, during the moving handle of plate, isolate the valve block moving axis that can rotate and rotate.

Form the upper casing of shell, the profile approximate ellipsoidal covers on lower casing.With the corresponding upper casing bellmouth in lower casing tubular position on, insert the corrugated tube of smoke exhaust, isolate valve block and can in the gap between upper casing and the lower casing, swing.At the shell periphery 2-3 hole arranged, shell is fixed on the wall on every side of oil smoke road junction with screw.

When smoke exhaust is stopped using, pulling handle is to the position of closing, isolate valve block and in the gap of upper casing and lower casing, move to the entrance point that lower casing inserts the pipe of public exhaust stack, public exhaust stack and upper casing are isolated, and the peculiar smell in the public exhaust stack just can not imported in the kitchen through upper casing by lower casing.When needs use smoke exhaust, pulling handle is to the position of opening, isolate second half position that is rocked to shell in the gap of valve block between upper casing and lower casing, open the pipe import that lower casing inserts public exhaust stack, the corrugated tube of the smoke exhaust that inserts the upper casing bellmouth is communicated with public exhaust stack, and oil smoke can enter in the public exhaust stack.

The utility model advantage is simple in structure, and it is all convenient to make, install, use, and it is installed on the mist extractor road junction in kitchen, during use, open the isolation valve block, not the time spent, close the isolation valve block, can prevent that the peculiar smell in the public exhaust stack from entering in the kitchen, contaminated air is felt under the weather the people.Cost is low, is easy to apply.

Embodiment of accompanying drawings:

Fig. 1 is a kind of kitchen oil flue isolating valve structure chart,

Fig. 2 is the A-A cutaway view,

Fig. 3 is the B-B cutaway view,

This kitchen oil flue isolating valve, its shell is divided into upper casing (4) and lower casing (3) two parts, lower casing (3) one ends are round tube shape, insert in the public exhaust stack (6), be equipped with between upper casing (4) and the lower casing (3) and isolate valve block (1), isolate valve block (1) below and extend handle (2), pulling handle (2) is isolated valve block (1) moving axis (7) that can rotate and is rotated.Smoke exhaust corrugated tube (5) inserts in the bellmouth of upper casing (4).When without smoke exhaust, pulling handle (2) is positioned between upper casing (4) and the lower casing (3) isolation valve block (1), is in the position of pass; When using smoke exhaust, pulling handle makes the isolation valve block move to another position of shell, the position that is in out.
