Embodiment Construction

[0023] Specific embodiments of the present application will be described in detail below in conjunction with technical solutions and accompanying drawings.

[0024] Such as figure 1 As shown, the present application adopts the basic design principle of seat-type personalized air supply. Commonly used seats are selected as the basic structure, and the fresh air ducts of the air-conditioning systems of building offices, gymnasiums, and vehicles are installed on the underside of the floor. The fresh air enters from the leg air supply pipes 1 on both sides of the seat, passes through the pipeline folding device 2 to the armrest air supply pipe 3, and finally is discharged from the terminal air outlet 4 on the front side of the armrest. During operation, the angle of the air supply port can be changed by using the air outlet angle regulator 8; the air supply volume can be adjusted by using the air volume regulating valve 9, thereby improving the airflow velocity. If the user need...

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...
