Ventilation power device in hidden indoor air purifier

Abstract

The invention provides a ventilation power device in a hidden indoor air purifier, belongs to the technical field of air purification, and aims at solving the problem that a ventilation power device in an existing air purifier is large in occupied space. The ventilation power device in the hidden indoor air purifier is arranged in a machine case; a bottom plate frame and a motor mounting plate are arranged in the machine case; the ventilation power device is arranged between the bottom plate frame and the motor mounting plate, and comprises an air duct pipe, a motor and a centrifugal impeller; the air duct pipe is in an arc shape, and is surrounded on the outer side of the centrifugal impeller; a ventilating duct is formed among the air duct pipe, the centrifugal impeller, the bottom plate frame and the motor mounting plate; a tubular mounting part which arches towards the bottom plate frame is arranged on the centrifugal impeller; a motor positioning barrel is arranged on the bottom plate frame and is arranged in the mounting part; the motor is arranged in the motor positioning barrel; the rotating shaft of the motor penetrates through the motor positioning barrel and is fixedly connected with the centrifugal impeller. The ventilation power device has the advantages of being simple in structure, good in stability and small in occupied space.

Description

technical field [0001] The invention belongs to the technical field of air purification, and relates to a ventilation power device, in particular to a ventilation power device in an indoor hidden air cleaner. Background technique [0002] Generally, the air in a closed space such as an indoor space is gradually polluted as time goes by due to the repeated breathing of living organisms in the indoor space, so it is necessary to frequently replace the air in the indoor space with fresh outdoor air. Air pollution. For this purpose, ventilation systems using total heat exchangers are usually used. [0003] The existing ventilation system is directly installed on the wall, which not only occupies indoor space, but also brings a lot of inconvenience to the placement of furniture. At the same time, it is blocked by furniture, or insufficient air volume causes partial circulation of purified airflow, which cannot achieve the full circulation effect of indoor air. At the same time, ...

Problems solved by technology

[0003] The existing ventilation system is directly installed on the wall, which not only occupies indoor space, but also brings a lot of inconvenience to the placement of furniture. At the same time, it is blocked by furniture, or insufficient air volume causes partial circulation of purified airflow, which cannot achieve the full circulation effect of indoor air. At the same time, the structure Specifically, a motor and an impeller driven by the motor are installed in the casing, and the air in the room is absorbed through the impeller and filtered through the filter screen before being transported back to the room. The existing ventilation system is not only large in size, but also prone to noise
