Positive-pressure vortex type disassembly-free washable range hood

Abstract

The invention relates to range hoods and particularly relates to a positive-pressure vortex type disassembly-free washable range hood. The positive-pressure vortex type disassembly-free washable range hood comprises an outer smoke exhaust pipe, an outer air inlet pipe, an inner front air inlet pipe, an air pump, a fixing rack, an inner rear air inlet pipe, an air exhaust wall hole, an inner smoke exhaust pipe, an oil smoke hood, air inlet branch pipes, air inlet end pipes and an air inlet wall hole. The outer smoke exhaust pipe is mounted on the outer side face of an exterior wall of a kitchen; and the inner end of the outer smoke exhaust pipe extends into the kitchen from the air exhaust wall hole. The outer air inlet pipe extends into the kitchen from the air inlet wall hole and is connected with the inner front air inlet pipe, the other end of the inner front air inlet pipe is connected with an air inlet mouth of the air pump, and an air outlet mouth of the air pump is connected and communicated with the inner rear air inlet pipe. According to the positive-pressure vortex type disassembly-free washable range hood, air in the whole kitchen is exhausted to the outside orderly in an air vortex manner, and meanwhile, oil smoke is prevented from being in contact with an impeller and a motor core, so that the real disassembly-free washing is realized.

Description

technical field [0001] The invention relates to a range hood, in particular to a positive pressure eddy current non-disassembly and cleaning range hood. Background technique [0002] Most of the existing range hoods used in the kitchen have a structure in which the motor drives the impeller to directly suck the oil fume into the exhaust pipe. The disadvantage of this structure is that after the range hood works for a period of time, the impeller, the motor core and the impeller A large amount of waste oil will stick to the surface of the working chamber. This waste oil not only affects the appearance and cleanliness of the range hood, but also greatly increases the resistance of the motor and impeller during work, affecting the normal working state of the impeller and the service life of the motor. , regularly cleaning this type of range hood is both very troublesome and increases the user's economic expenditure. Some range hoods are equipped with a cover outside the impell...

[0002] Most of the existing range hoods used in the kitchen have a structure in which the motor drives the impeller to directly suck the oil fume into the exhaust pipe. The disadvantage of this structure is that after the range hood works for a period of time, the impeller, the motor core and the impeller A large amount of waste oil will stick to the surface of the working chamber. This waste oil not only affects the appearance and cleanliness of the range hood, but also greatly increases the resistance of the motor and impeller during work, affecting the normal working state of the impeller and the service life of the motor. , cleaning this type of range hood regularly is very troublesome and increases the user's economic expenditure.

Some range hoods are equipped with an outer cover on the impeller to solve this problem, but this cover will weaken the smoke exhaust ability of the impeller
