Abstract

The invention relates to a convection type fume extractor which is provided with a flue hole and a centrifugal fan volute that are crossed vertically, an upper opening of the flue hole is provided with a valve fixed by a hinge support, and the valve can be separated from or cover on the upper opening of the flue hole; an opening on an interlayer ring at the periphery of the opening of the flue hole is connected with a buffer stop bin, an air spraying nozzle fixed on the buffer stop bin is communicated with an interlayer space, a rectification smoke removing hole is arranged on an upper opening of the buffer stop bin, a smoke cover is arranged on the lower opening of the flue hole, the upper end of an air conveying pipe on the smoke cover is inserted into the connecting part of the volute and the flue hole and ventilated with the connecting part mutually, a fan blade assembly is arranged in the volute to form a centrifugal fan, and an air outlet of the centrifugal fan is communicated with the ring interlayer space.

Description

Technical field: [0001] The invention relates to a convection type range hood Background technique: [0002] There is a convection type range hood, which is disclosed through the inventor's invention patent document No. 2004100470183 and the trial production of related prototypes, but has not yet been put into industrial production. The present inventor obtained a brand-new design proposal through subsequent research on the same subject. Invention content: [0003] The invention provides a new convection range hood, which adopts hot air to be automatically convectively exhausted in its flue and uses a controllable valve to shut off the smoke convection channel, and then the blower extracts the smoke below the valve and discharges it to the The method above the valve is combined to realize the sufficient and stable one-way outflow of hot air in the convection channel. [0004] The beneficial effects of the present invention are: the flue gas convection channel of the pres...
