Description

Separate range hood with smoke collection and diversion structure

The utility model relates to a separate range hood with a smoke collection and diversion structure, in particular to a separate range hood with a smoke collection and diversion structure.

For the range hood of the prior art, taking the island type range hood 9 as an example, a smoke collection hood 93 is arranged above its top wall 91 , and the exhaust motor 95 is arranged in the smoke collection hood 93 . The oil fume filter 96 is disposed on the bottom wall 92 . The problem that it may produce is that the noise of the exhaust motor 95 cannot be avoided in the house. Furthermore, the air flow passes through the oil fume filter 96 and the fume collecting hood 93 , and then is exhausted by the exhaust motor 95 to the outside of the range hood 9 , and the oil fume usually stagnates between the top wall 91 and the bottom wall 92 . There are many corners of the fume collecting hood 93, and oil fume is easy to stagnate, and the air flow cannot be discharged smoothly. The above-mentioned problems lead to the low efficiency of the range hood 9, which tends to accumulate lampblack and reduce the service life.

Another current technology is to change the exhaust motor to the outside of the smoke collection hood, and the exhaust motor is arranged outside the house to reduce noise, similar to the separated air conditioner. However, the fume collecting hood is manufactured by bending a metal plate, and is usually connected to the casing by screws or rivets. The inside of the fume collecting hood, that is, the part where the fumes are concentrated, is unavoidably exposed to some fixing screws. These screws for fixing are not only unsightly, but also cause turbulent flow of oily fume, reducing the fluency of oily fume flow. Furthermore, oil fume adheres to the screws, making it difficult to clean and wipe.

Therefore, how to overcome the above defects by improving the structural design has become one of the issues to be solved in this technical field.

The technical problem to be solved by this new model is to provide a separate range hood with a smoke collection and diversion structure for the deficiencies of the prior art. It provides a smoke collection box that can reduce the number of exposed fixing screws to improve the smooth flow of the smoke. , increase the appearance and easy to clean.

In order to solve the above-mentioned technical problems, another technical solution adopted by the present model is to provide a separate range hood with a smoke collecting and guiding structure, which includes a casing and a smoke collecting box. The casing has an upper wall, a lower wall and an air inlet port, and the air inlet port passes through the upper wall and the lower wall. The smoke collecting box covers the air inlet port and protrudes from the upper wall. The smoke collecting box includes an outer box wall, a flow guiding shell, and a cover plate. The outer box wall is fixed around the air inlet port. The guide housing is arranged inside the outer box wall. The cover plate is fixedly connected to the top of the outer box wall. The top end of the guide housing is fixedly connected to the cover plate. The cover plate has an air outlet port, and the air outlet port connects the smoke collecting box to the air inlet port of the casing. The bottom edge of the air guide housing does not exceed the lower wall of the casing and is a predetermined distance away from the lower wall. The bottom edge of the flow guide housing has a plurality of outward shielding wings. The plurality of shielding wings are adjacent to the inner surface of the air inlet port, so that the oil fume passes through the flow guide housing to reduce turbulent flow, and then is discharged from the air outlet port of the cover plate.

One of the beneficial effects of the new model is that the separate range hood provided by the new model has a smoke collection and diversion structure, which arranges the diversion shell of the smoke collection box inside the outer box wall, and the cover plate is fixed The ground is connected to the top of the outer box wall, reducing the exposure of the fixing element to the area where the oil fume flows inside the smoke collection box, thereby reducing the turbulence of the oil fume or adhering to the fixing element, so that the oil fume passes through the guide shell more smoothly. The air outlet port of the cover plate is discharged outward, which is beneficial to cleaning and wiping.
