Description

Fume exhaust fan

Technical Field

The utility model relates to an oil smoke purifier, especially a range hood.

Background

The range hood has become one of the indispensable kitchen household electrical appliances in modern families. The side-draft range hood absorbs most of oil smoke close to a cooking bench in an arc form by using a vortex air pressure principle, so that adverse effects on human health can be reduced, and the suction effect of a power source is basically not reduced because the power source is close to the cooking bench.

Chinese utility model patent No. 201820965653.7 discloses an automatic mechanism that opens and shuts of smoke deflector, including smoke deflector, electric putter, push rod, swing spare, the protection casing, first supporting seat and second supporting seat, the protection casing setting is in the inside of range hood's supporting framework and constitute a space cavity with the supporting framework inboard, first supporting seat sets firmly in the inside of space cavity, electric putter sets up in the inside of space cavity and rotates with first supporting seat to be connected, electric putter's power take off end and the one end fixed connection of push rod, swing spare is equipped with rotates the first connecting portion of being connected with the second supporting seat, rotate the second connecting portion of being connected with the push rod, with smoke deflector fixed connection's third connecting portion.

Current side suction type range hood is shown as above-mentioned patent, the air inlet mode is mostly put the air inlet in the middle (the air intake mainly distributes the position on the upper side in the centre of panel), the cigarette board is located the upper portion of air intake, and the air inlet mode is put the air inlet under for (the air intake mainly distributes in the lower part of panel) range hood and generally can cancel the cigarette board or will keep off the length of the fore-and-aft direction of cigarette board and do short, its reason is mainly put the air inlet mode under and sets up behind the cigarette board, there is the risk of beating a pot when opening, and can interfere with the utensil that evaporates when evaporating food, the influence is the experience of evaporating food.

In order to improve the oil smoke suction capability of the side-draft range hood, the main adopted method comprises the following points: firstly, set up the air inlet mode to put the air inlet down, but in order to avoid keeping off the risk of beating a pot of cigarette board, and will keep off the cigarette board and cancel or will keep off the length of the fore-and-aft direction of cigarette board and make short, this although makes the air intake of lampblack absorber be close to the smoke source, has improved the oil absorption cigarette ability, but under the great condition of oil smoke, the oil smoke escapes easily. Secondly, the air inlet mode is still mid-set air inlet (mainly for avoiding the risk of beating a pot of a smoke baffle), and the air volume and the back pressure of the fan system are increased for preventing the oil smoke from escaping, but the cost is greatly increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that to prior art not enough, provide one kind and put the air inlet down and can avoid keeping off the range hood of the pot risk of beating of cigarette board, improving oil absorption cigarette ability.
