Central Hair Drying System

Abstract

A central system for delivery of an airflow at a variety of temperatures and rates to individual dryers, replacing the individual motor, fan and heating elements in the dryer. The system may produce a heated airflow based on multiple user-input temperature and airflow level commands. Multiple dryer users can independently control their desired temperature and the airflow level. The system may utilize an HVAC air delivery system and comprises a central control system with preprogrammed algorithm to operate the HVAC to achieve the desired results. A number of sensors can provide inputs to the control system.

Description

FIELD OF THE INVENTION[0001]The present teachings generally relate to a central system for delivering independently controlled temperature and airflow rate to a plurality of individual dryers and thus providing a reduced-weight and low-noise dryer.BACKGROUND OF THE INVENTION[0002]A variety of hot air blowing devices are known for the drying of human and animal body parts and, in particular, drying, dehumidifying, shaping and styling of hair. The hair dryer is usually hand held and portable. Such devices, whether portable or not, commonly contain a housing which contains a powerful electric motor, a fan, heating elements, control features and a conduit to deliver directional heated or non-heated airflow.[0003]The conventional hair dryer poses several health hazards to the professional users and their clients. The conventional hand-held hair dryer device is relatively heavy and hence challenging to maneuver, which consequently poses an ergonomic hazard for a professional user, for exa...

AI Technical Summary

Benefits of technology

The present invention is a system for controlling the temperature and pressure of airflow in a dental handpiece. The system includes two ducts, each containing a different airflow, and Y-connectors which combine the airflows to create a third airflow. Dryer handpieces are connected to the Y-connectors and each has its own damper to control the airflow. The system also includes a control system that can adjust pressure and temperature at each handpiece. Additionally, the system has a preheater and a heater to adjust the temperature of the airflow before it reaches the dental handpiece. The technical effect of this invention is to provide precise control over the airflow and pressure in a dental handpiece, which can enhance dental procedures and increase patient safety.

Problems solved by technology

The conventional hair dryer poses several health hazards to the professional users and their clients.

The conventional hand-held hair dryer device is relatively heavy and hence challenging to maneuver, which consequently poses an ergonomic hazard for a professional user, for example hairdressers, groomers and beauticians.

Another occupational hazard of a conventional hand-held hair dryer is the noise emission generated by the motor and the fan, typically in the range of 70 dB to 90 dB.

During simultaneous operation of several dryers, the noise level increases considerably.

Long-term exposure of professionals and clients to the noise is undesirable.

Another negative aspect of the high noise level is the general acoustic pollution which impedes in-person and phone communication between the professional users and the clients.

Utilization of the conventional hair dryer poses hygienic risk which stems from the fact the air drawn into the dyer and then directed toward a client, is a recirculated indoor air.

When a conventional dryers are operated in a professional facility with multiple clients, there is a high risk of transporting contaminated air that may expose clients to other clients' germs, bacteria, microorganisms, fungi, skin particles and dust.

Several other negative aspects of the conventional dryer exist due to the fact that every dryer contains heating elements and a powerful electrical motor.

A conventional dryer has to be frequently replaced due to a reduction in performance and has a typical short lifespan of only about 200 to 300 hours, which substantially increases the operational costs of the facility.

In a typical commercial facility operating dryers the heat generated by the individual motors of the dryers significantly affects the ambient temperature.
