Description

Integrated kitchen of grease proofing cigarette backward flow

Technical Field

The utility model relates to the technical field of integrated stoves, in particular to an integrated stove capable of preventing oil smoke from flowing back.

Background

The integrated kitchen range is a kitchen appliance integrating multiple functions of a range hood, a gas kitchen range, a sterilizing cabinet, a storage cabinet and the like, and is also called an environment-friendly kitchen range or an integrated environment-friendly kitchen range in the industry. Has the advantages of space saving, good fume exhausting effect, energy saving, low consumption, environmental protection and the like. The oil absorption rate of the general integrated kitchen ranges reaches 95%, the higher the oil smoke absorption rate is, the better the quality is, and the oil smoke absorption rate of some brands of integrated kitchen ranges reaches 99.95% of limit indexes. However, most of the existing integrated stoves have the condition of oil smoke backflow when a fan is closed or the fan power is turned on to the maximum, and the oil smoke backflow needs to be limited at the moment.

The Chinese patent with the publication number of CN209026861U discloses an integrated kitchen of grease proofing cigarette backward flow, including holding the subassembly and induced drafting the subassembly, hold the subassembly and include fire circle, ignition switch, hold cabinet, kitchen range and drawer, the both ends of auxiliary pipeline run through respectively the blast pipe with the cover that induced drafts, works as when the rotational speed of fan accelerates, the inside oil smoke of cover that induced drafts increases, this moment the inside air velocity of flow of blast pipe accelerates, and drives the inside air of auxiliary pipeline to flow in the blast pipe, thereby make the inside pressure of auxiliary pipeline reduces, and produces the suction and adsorb the inside oil smoke of cover that induced drafts, avoided the oil smoke to get rid of completely the backward flow phenomenon that produces, the baffle with the cover that induced drafts rotates to be connected, and the quality is lighter, works as when the fan rotates, the baffle can upwards open, with the air exhaust into the cover that induced drafts is inside, works as the fan closes the back, the baffle is because gravity effect falls down, will the cover that induced drafts is sealed, thereby has avoided backward flow.

However, the device still has the defects that: when the fan is closed or the fan is opened to the maximum, high-concentration oil smoke rapidly enters the smoke exhaust pipe, and although an auxiliary pipeline is added, the oil smoke still flows back along the pipeline under the condition of high concentration of the oil smoke.
