Description

Submerged range hood with linked upper baffle and lower baffle

Technical Field

The invention relates to the field of kitchen appliances, in particular to a submerged range hood with an upper baffle and a lower baffle linked.

Background

The common range hoods on the market at present have three types, namely a top suction type range hood, a side suction type range hood and a submerged type range hood. The ceiling type range hood is generally arranged in a better matching cabinet, the upper surface of a smoke collecting cover of the ceiling type range hood is flatly attached to the bottom surface of the cabinet, so that the mounting position is generally higher, but an air inlet of the ceiling type range hood is far away from a cooking bench, the smoking effect is poorer, and in order to improve the smoking effect, the power of a motor needs to be increased, so that the defects of cost rise, noise increase and the like are caused. In addition, the top-suction type smoke exhaust ventilator is higher in installation position and is easy to touch during cooking; the distance between the air inlet and the cooking bench is shortened, the smoking effect is improved, the size of the air cabinet system is larger, but the whole size of the smoke collecting cavity is smaller, so that the air cabinet system is arranged on the upper part or the middle part, and part of the smoke collecting hood is positioned above the plane of the cabinet; in addition, the side suction machine and the cooking bench form a certain included angle, the smoke collecting effect is poor, and the oil smoke escapes. A submerged range hood, which realizes downward movement of a negative pressure region, for example, a lifting range hood with the patent number ZL201621063063.2 (the granted publication number is CN206207511U), solves the problem that a cooking bench in an air inlet is too far by descending the air inlet, but the bottom of a smoke collection cavity is arc-shaped (or inclined), when oil smoke ascends, the oil smoke directly contacts with the bottom of the smoke collection cavity, and the air inlet has the problems of small negative pressure and no smoke baffle plate, so that the oil smoke escape phenomenon is serious, and the smoke suction effect is not ideal; in addition, the distance between the air inlet and the cooking bench is short, and the smoke baffle plate is arranged at the air inlet, so that the pot collision problem can occur, so that the utility model with the patent number of CN201820985116.9 provides a novel cooking stove, wherein the air inlet is arranged below the smoke collecting cavity, and the air inlet and the smoke baffle plate are additionally arranged at the upper part of the smoke collecting cavity, but the power of the motor can be increased and the cost is increased due to the use of the two air inlets and the smoke baffle plate; in addition, because the upper part of the cooking bench is also provided with the air inlet, the plane where the upper air inlet of the range hood is positioned occupies more space, the operating space of a cooker is reduced, and the phenomenon of collision is easy to occur.
