Description
Technical Field
The invention relates to an oil fume purification device, in particular to a range hood.
Background
The range hood has become one of the indispensable kitchen household electrical appliances in modern families. The range hood works by utilizing the fluid dynamics principle, sucks and exhausts oil smoke through a centrifugal fan arranged in the range hood, and filters partial grease particles by using a filter screen. The centrifugal fan comprises a volute, an impeller arranged in the volute and a motor driving the impeller to rotate. When the impeller rotates, negative pressure suction is generated in the center of the fan, oil smoke below the range hood is sucked into the fan, accelerated by the fan and then collected and guided by the volute to be discharged out of a room.
Currently, the common range hoods on the market include a top suction type, a side suction type and a bottom suction type. The top-suction type range hood adopts the oil smoke rising principle, generates a negative pressure area right above a cooking bench, sucks and exhausts naturally rising oil smoke generated during cooking, and has the advantages of fashionable and concise appearance, larger air volume, larger space suitability and capability of catching oil smoke far away from the cooking bench.
Referring to fig. 12 and 15, a conventional top-suction range hood includes a smoke collecting hood 1 ' and a fan frame 2 ' disposed above the smoke collecting hood 1 ', a smoke guide plate 4 ' disposed below an air inlet of the smoke collecting hood 1 ', and an oil cup 5 ' disposed at a bottom of a rear side of the smoke collecting hood 1 '. The oil cup 5 'is an independent component, and the installation mode is usually that the folded edges 51' at the left and right ends of the oil cup 5 'are clamped into the hook groove at the bottom of the smoke collecting hood 1'. Not only the distance between the hook grooves is small, and the two ends of the oil cup 5' need to be operated simultaneously, but also the visualization degree is extremely low in the installation process, and the whole installation is very laborious. When the oil cup 5 'is disassembled, due to the design that the hook groove is internally provided with the positioning and clamping structure for the upper folded edge 51' of the oil cup 5 ', the oil cup needs to be slightly forced outwards during disassembly, and the risk of oil splashing in the oil cup 5' caused by excessive force can exist. In addition, the oil cup 5' is usually formed by tailor welding and is in a slender groove shape, so that cleaning dead corners exist, and the oil cup is not easy to clean.
Referring to fig. 12 to 14, after the oil cup 5 'is installed, a gap exists between the oil cup and the smoke collecting hood 1' in the vertical direction, and a gap exists between the oil cup and the wall 100 in the front-rear direction. The air inlet is provided with the smoke guide plate 4 ', so that negative pressure generated by upward air suction of the fan system can be diffused to the periphery of the smoke guide plate 4 ', namely, negative pressure regions can be formed on the periphery of the smoke guide plate 4 ', and as shown by arrows in figure 12, smoke can be sucked in the front, the rear, the left and the right negative pressure regions. It is advantageous to suck the oil smoke in the left, right and front directions, but when the oil smoke is sucked in the rear direction, a part of the oil smoke will impact on the upper edge of the oil cup 5 ' along the smoke guide plate 4 ', and then be sucked from the gap between the smoke guide plate 4 ' and the oil cup 5 ', as shown by the arrow in fig. 14, because the gap is small, the speed of the oil smoke reaching the gap will decrease rapidly, the oil smoke will condense at the edge of the oil cup 5 ', and oil drops will form to drop along the oil cup onto the cooking bench for a little time. In addition, most of the oil smoke will follow the inclined plane at the front side of the oil cup 5 ', pass through the gap between the oil cup 5' and the wall 100, and then be sucked into the range hood through the gap between the oil cup 5 'and the smoke collecting hood 1', as shown by the arrow in fig. 13. However, when the oil smoke passes through the gap between the oil cup 5 'and the wall 100, the oil smoke will be rapidly reduced in speed, and the oil smoke will form a "traffic jam" state in the gap between the oil cup 5' and the wall 100, so that most of the oil smoke passing through the gap will be condensed on the wall 100, and after a long time, oil drops will appear on the wall, thereby causing the common phenomenon of wall oil hanging in the market.
In addition, there is also an integrated smoke guide plate, which integrates the oil cup on the smoke guide plate, but still cannot solve the above-mentioned problems of oil hanging and oil dripping.
