Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Examples

This embodiment discloses a lampblack absorber, it is shown with reference to figure 1 ~ 2, the lampblack absorber includes lampblack absorber body 2, usually, the lampblack absorber body 2 of top-suction lampblack absorber leans on the wall installation, and is accomodate in cupboard 3, and the exhaust pipe 26 of lampblack absorber is arranged away from the calandria in kitchen furred ceiling 1. Considering that the smoke collecting cavity 4 of the top-suction type range hood is shallow, the negative pressure suction force is relatively weak, the smoke collecting cavity is positioned right above a cooker and has a larger distance with the cooking bench 5, the flowing distance of smoke in the vertical direction is longer, oil drops are sucked along with hot smoke, the phenomenon that the oil drops turn back before entering the smoke collecting cavity 4 due to the fact that the gravity action cannot be overcome can occur, the oil drops turning back can interact with the smoke and other oil drops when the oil drops fall back, the outward escape of the smoke and the splashing of the oil drops are caused, and the smoke exhaust effect of the range hood is reduced. In order to solve this technical problem, improve the lampblack absorber effect of discharging fume, improve and be used for the culinary art to experience, lampblack absorber among this embodiment technical scheme still includes air curtain portion, and this air curtain portion sets up on above-mentioned lampblack absorber body, and above-mentioned air curtain portion has supply-air outlet 6, and above-mentioned supply-air outlet 6 is located the outside of above-mentioned collection smoke chamber 4, and encircles 4 a week settings in above-mentioned collection smoke chamber, and the air current that comes out from above-mentioned supply-air outlet 6 encircles lampblack absorber body top of a kitchen range a week and forms.

Cold air (relative to hot smoke generated by the cooker during cooking) is fed into the upper part of the cooking bench 5 through the air supply outlet 6, the cold air surrounds the cooking bench 5 for a circle to form an air curtain, the flow speed of air flow of the air curtain is reduced when the air flow is close to the cooking bench 5, the air flow deflects gradually under the suction action of an exhaust fan 24 arranged in the range hood body, and one part of air flow is directly converged with the hot smoke generated by the cooking above the cooker, is sucked into the smoke collection cavity 4 and is then exhausted through an exhaust pipe 26; the other part of the air curtain flows to the upper part of the stove to fill a negative pressure area generated by rising of hot flue gas.

On the other hand, above-mentioned supply-air outlet 6 is located the outside in collection smoke chamber, and when its air-out formed the air curtain, can not prevent the oil smoke to the collection smoke chamber 4 flow of lampblack absorber body, effectively avoids air current flow direction and oil smoke flow direction to take place the convection current, and then influences the lampblack absorber smoke exhaust effect.

Specifically, the air curtain portion further comprises an air inlet 12 and an air flow channel 14 communicating the air inlet 12 with the air supply outlet 6, and the air flow channel 14 is located outside the smoke exhaust channel 18 of the range hood body and arranged around the smoke exhaust channel 18 for a circle. Fresh air enters the airflow channel 14 from the air inlet 12 and is exhausted from the air supply outlet 6 at the flowing tail end of the airflow channel 14, and blown air forms an air curtain around the periphery of the cooking bench to block convection of oil smoke and ambient air.

Optionally, the air curtain portion includes a casing 16, an air supply pipe 20 and a blower 22, the smoke collection chamber 4 and the smoke evacuation channel 18 are both disposed in the casing 16, and the airflow channel 14 is formed in the casing 16 outside the smoke evacuation channel 18 and the smoke collection chamber 4; the air supply outlet 6 is arranged on the shell 16; the blower 22 is provided on the air supply pipe 20, and one end of the air supply pipe 20 is provided with the air inlet 12, and the other end thereof communicates with the housing 16. The air curtain part adopting the structural design has flexible appearance size and convenient assembly, can be matched with various top suction type range hoods, is suitable for the reconstruction of the existing range hoods, and can be integrated with the range hoods selected by customers in new assembly and repair.

Preferably, a diffuser 8 is provided at the air supply port 6, an air supply panel 10 is provided outside the diffuser 8, and the air supply panel 10 is detachably attached to the casing 16. The air diffuser 8 adopts low-flow-resistance aluminum alloy blades, the guide of a plurality of blades is adjusted simultaneously through the universal driving shaft, and the air diffuser can be adjusted according to the distance between the range hood and the cooking bench, so that the air curtain can completely cover a cooking area. The air supply panel 10 is designed to be easily disassembled and assembled, so that the air diffuser 8 can be conveniently adjusted and cleaned. For example, the mounting is performed by a clamping manner, a screw thread fit mounting, and the like.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
