Rotary negative pressure balance system

Abstract

The invention discloses a rotary type negative pressure balance system which can comprise a spacing body used for spacing the interior of a room from the exterior of the room. The room is provided with a negative pressure generating device capable of generating a negative pressure environment in the room; the air exchange device is arranged in an air flow channel formed in the spacer; the airflow channel is used for communicating the indoor space with the outdoor space. According to the rotary type negative pressure balance system, when the range hood is used, indoor air and outdoor air can be communicated by starting the ventilation device, a series of problems such as ceiling deformation and cracking, door and window airtightness reduction and toilet smell returning caused by large negative pressure generated in a room are avoided, the door and the window do not need to be opened, and operation is easy and convenient. The system is provided with the composite filter screen, air entering a room can be filtered, and the indoor air quality is ensured.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, in particular to a rotary negative pressure balance system. Background technique [0002] A range hood, also known as a range hood, is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove, which can quickly remove the burning waste of the stove and the oil fume that is harmful to the human body during the cooking process, and discharge it to the outside. Guarantee role. [0003] Usually when the range hood is used in the kitchen, if the doors and windows are all closed, the huge suction of the range hood will generate a large negative pressure in the room, causing the ceiling to be slightly deformed, and the outdoor air will also enter the room through the gap between the doors and windows. The choice will cause problems such as deformation and cracking of the ceiling and poor sealing of doors and windows. [0004] In addition, the...

AI Technical Summary

Problems solved by technology

[0003] Usually, when using a range hood in the kitchen, if all the doors and windows are closed, the huge suction of the range hood will cause a large negative pressure in the room, causing a slight deformation of the ceiling, and outdoor air will also enter the room through the gaps in the doors and windows, and accumulate over time. The choice will cause problems such as deformation and cracking of the suspended ceiling, and poor sealing of doors and windows.

[0004] In addition, a large negative pressure will cause the odor in the bathroom air duct to be sucked back into the room. Even if the bathroom exhaust duct has a check valve, it is difficult to completely seal it.

[0005] If some doors and windows are opened to avoid negative pressure problems, a large amount of outdoor air will directly enter the room without filtering, and harmful substances such as pollutants and PM2.5 in the air will seriously affect indoor air quality and damage human health.
