Description

Technical Field

[0001] The utility model relates to the technical field of kitchen equipment, in particular to an air outlet seat and a range hood. Background Art

[0002] In modern kitchens, range hoods have become one of the essential equipment. Their main function is to collect and exhaust oil smoke or water vapor during cooking, thereby protecting the kitchen environment. Its main working principle is that the main motor in the inner cavity of the machine body rotates at high speed to drive the impeller in the centrifugal fan to rotate, thereby generating a large negative pressure in the preset inner cavity. The cooking oil smoke is sucked into the range hood due to atmospheric pressure and airflow, flows along the inner wall of the fan, and is discharged outdoors or to the public flue.

[0003] At present, the exhaust outlets of the more common range hoods are basically arranged upward. After the unfiltered oil smoke condenses, it will naturally flow back to the interior of the range hood cavity due to gravity, and will eventually be collected in the oil cup below the range hood. However, with the continuous development of the form and performance of range hoods, in order to solve the noise pollution problem of users using range hoods, a split or ceiling-mounted range hood has appeared on the market. The main principle is that the noise source is farther away from the user during operation. According to the acoustic noise pollution theory, the sound pressure perceived by the user will be lower. Combined with other noise reduction measures, the noise problem when the user uses the range hood can be reduced. This type of range hood has a common feature, that is, the exhaust port needs to be placed horizontally. The above-mentioned unfiltered oil smoke cannot naturally flow back to the interior of the range hood after condensation, and eventually gathers in the exhaust pipe or leaks through the gap at the exhaust pipe interface, polluting the range hood body shell and kitchen environment.
