Filtered Airflow for Exercise Machines

摘要

The blower motor is powered by 115 volts from the circuit board that runs all of the other functions of the machine. This blower assembly is designed with enough draw to pull the incoming air across air filters in order to keep the blower and the operator free of air-borne debris. The filtered air is then supplied into the hollow framing of the equipment to be distributed to the operator, circuit boards and motors through holes made in the equipment framing. Using the machine frame as the ductwork also preserves the style and design of the equipment. Not only is this a new idea to the exercise equipment industry, but I believe it is necessary for an exercise machine to deliver clean air to the operator in order to keep their good health in mind. A blower without an air filter will send bacteria onto the user who is breathing heavy and sweating. This seems to defeat the purpose of exercising and the benefits of getting your heart rate and breathing accelerated for a length of time. The air is not mechanically cooled but typically exercise rooms are air conditioned anyhow.

1. The air being delivered into the exercise machine is filtered, catching debris and bacteria before it collects on the blower wheel while also preventing contaminated air from blowing onto the user. A clean blower will also maintain proper air flow. Various size holes in the pipe can be used and will not clog with debris because it will be trapped in the air filter before it gets to the air filter box and blower assembly. Air channels can be created to direct air onto circuit boards or even drive motors to keep them cooler as well. Larger holes in the pipe can be used to install a nozzle that is directional and closable; giving the user even more control over the exact location and the amount of air being directed from each nozzle. A two speed motor can be used to vary the amount of air output, giving the user a low speed and hi speed option. Air filters can be replaced as needed to ensure good air flow and filtering capability. The blower assembly proto type works well. I have included drawings with the blower mounted in various locations and on several different machines. The blower assembly is mounted to and supplies filtered air into the existing pipe framework of the machine. The prototype blower assembly has an outlet that fits into a 2″ p.v.c. pipe which is simulating the approximate diameter and length of the metal framing already being used for the equipment.
