Personalized air supply device embedded in seat armrests

Abstract

Belonging to the fields of ventilation patterns, air distribution, pollutant control, and human body comfort research, the invention relates to a personalized air supply device embedded in seat armrests. The invention is characterized in that the device comprises seat leg air supply pipes, pipeline folding apparatuses, armrest air supply pipes, end air outlets, multistage telescopic sleeve pieces, higher stage sleeve piece bottom flanges, lower stage sleeve piece top grooves, air outlet angle regulators, and air volume regulating valves, etc. By cleverly making use of the free spaces existing at the seat armrest sides when people seat, the personalized air supply device is embedded in seat legs and armrest structures. The air supply pipes can achieve free folding of the seat armrests through the multistage telescopic sleeve piece apparatuses. The armrest end air outlets are utilized to send warm and clean air subjected to heat and wet treatment to a breathing zone in front of the human body, thus preventing a cold air blowing sense and improving human body local thermal comfort. The invention is suitable to be used in offices, theaters, stadiums, vehicles and other environments.

Description

technical field [0001] The device belongs to the research fields of ventilation mode, air flow organization, pollutant control and human comfort, and relates to a personalized air supply device embedded in the armrest of a seat. Background technique [0002] With the development of air-conditioning and ventilation systems for buildings or vehicles, people have higher and higher requirements for environmental comfort. The personalized air supply system can help personnel actively participate in and set the thermal environment required by individuals, deliver fresh air directly to the human breathing zone, and use a small air supply volume to improve the air quality and thermal comfort felt by personnel in the microenvironment sex. In this context, in architectural offices, theaters, stadiums and transportation environments, the requirements of sitting and standing personnel for personalized environments have prompted the development of new seat-type personalized air supply s...

Problems solved by technology

However, its limitation is that the design of the air supply outlet of the pipe nozzle of the air supply device occupies most of the activity space on the front side of the human trunk, which is very easy to cause inconvenience when people work or take vehicles; at the same time, the fresh air after processing is directly If the temperature, humidity and outlet wind speed are not properly controlled, it will easily cause discomfort to the personnel; in addition, when the personnel using this personalized air supply device suffers from infectious respiratory diseases, it will increase the air temperature around them. The likelihood and extent of a person being infected
