Technical Field
[0001] The utility model belongs to the technical field of range hoods, and particularly relates to a range hood. Background Art
[0002] A range hood is a very common kitchen appliance in daily life. By starting the range hood, the oil fumes generated during the cooking process can be first sucked into the interior of the range hood and then further transferred to the outside atmosphere. However, the existing smoking structure of the range hood generally sets a smoke guide cavity at the bottom of the range hood body and an air inlet communicating with the fan device at the top of the smoke guide cavity. The air inlet generally has a relatively large air suction area, resulting in a relatively low air suction pressure of the range hood for the oil fumes generated during the cooking process, so that the oil fumes are likely to escape to the outside, and the smoking effect of the range hood is not ideal. Summary of the Utility Model
[0003] The purpose of the utility model is to overcome the problem that the existing range hood has a relatively low air suction pressure for the oil fumes generated during the cooking process, resulting in the oil fumes being likely to escape to the outside and the smoking effect of the range hood not being ideal, and to provide a range hood with a smoke gathering effect and a good oil fume suction effect.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A range hood, comprising a range hood body, the range hood body is provided with a smoke guide cavity with an opening at the bottom, and a smoking port communicating with the inner side oil fume cavity of the range hood body is arranged at the top of the smoke guide cavity; it further comprises a smoke baffle arranged in the smoke guide cavity and having a preset distance from the smoking port. The smoke baffle is adapted to the shape of the smoke guide cavity, and there is at least a distance between the smoke baffle and the front side and the left and right sides of the smoke guide cavity, so that an air inlet structure is formed between the outer side of the smoke baffle and the inner side of the smoke guide cavity. The smoke baffle is provided with a filtering module on the inner side and air holes at the bottom communicating with the filtering module, and the air holes are arranged on the front side and the left and right sides of the smoke baffle.
[0006] Compared with the prior art, the range hood of the utility model forms an air inlet structure that surrounds the front side and the left and right sides of the smoke baffle at the bottom of the range hood body and communicates with the smoking port by arranging a smoke baffle in the smoke guide cavity and leaving a distance between the smoke baffle and the front side and the left and right sides of the smoke guide cavity, so that the air inlet structure has a relatively high air suction pressure, effectively preventing the oil fumes generated during the cooking process from escaping to the outside, and having a good smoke gathering and smoking effect. Moreover, when the oil fumes flow through the smoke baffle and enter the air inlet structure, part of the oil fumes can flow through the air holes and be absorbed by the filtering structure on the inner side of the smoke baffle to form a clean air flow and enter the smoking port, thereby reducing the accumulation of oil fumes in the fan device, making the fan device work more smoothly, and having a better filtering effect of the range hood.
