Description

A PERSONAL CLIMATE CONTROL DEVICE
RELATED APPLICATION
This application relies upon U.S. Provisional Application Ser. No. 60/830,430, filed July 13, 2006, the content of which is hereby incorporated in its entirety.
TECHNICAL FIELD
The present invention relates to an apparatus for regulating the body temperature of a human and in greater detail the present invention includes a portable apparatus for cooling and heating the core of the human body.
BACKGROUND
A person working in a warm environment or performing tasks for which protective clothing is required may find the working conditions uncomfortable and may even experience a deterioration in performance or increased fatigue due to the build-up of body heat. Additionally construction workers also experience the same heat discomfort. This may result in elevated body temperatures and increased stress.
One technique for keeping the body cool in such situations has been to employ a coolant-chilled garment. A coolant liquid such as chilled water is pumped through tubes which are attached to the garment to chill the garment. Such systems are typically closed systems in which the coolant is circulated through a cooling unit to maintain the garment and coolant at a chilled temperature.
Although the entire system may be self contained, a person wearing the chilled garment must be tethered at all times to the cooling unit. The tether, of
1
s course, restricts the mobility of the wearer of the garment. Cooling by means of a liquid increases the weight the cooling garment and also the complexity and cost of the system. In addition, the cooling and tank units that are required for the liquid coolant may impede the movements of the wearer or others when the system is used in confined areas or when movement in the work area is necessary.
Additionally, there have been systems employing air or refrigerated air for cooling individuals. However, these systems have been uncomfortable to wear, cumbersome to use, and frequently have the same disadvantages as the liquid cooling systems. Thus, what is needed is an apparatus for regulating the body temperature of a human that is both portable and easy to use while providing comfort to the user.
SUMMARY
The present invention comprises an apparatus for regulating the body temperature of a human by including a portable apparatus for cooling and heating the core of the human. The present personal climate control device provides a hands free cooling and heating device which may be clipped to the belt or pant of a wearer. In cooling the body the device amplifies evaporation and decreases the chances of shirt to skin contact. In greater detail, the present invention includes a personal climate control device comprising a housing for venting and directing an airflow upward and across a core of a human body. The housing includes a first and second opposed opening formed within the housing and a fan located within the housing. The fan is capable of directing an air stream from the first opening and towards the second opening of the housing so that the air stream is directed across the core of the human body. An electric motor operatively connected to the fan with a power supply connected to the electric motor. A clip is further included and connected to the housing for securing the housing to the human body.
The motor may be a piezoelectric motor with the fan selected from the group consisting essentially of a tube-axial fan, a centrifugal radial fan and combinations thereof. The device may further include a pre-chilled element located within the housing and operatively located such that air passes over the pre-chilled element to produce a cooled air stream. The device may also include a pre-heated element located within the housing and operatively located such that air passes over the pre- heated element to produce a heated air stream.
In a further embodiment, the personal climate control device includes a heating element located within the housing and operatively located such that air passes over the heating element to produce a heated air stream. An additional embodiment includes a mechanical heating and cooling apparatus located within the housing for cooling and heating the air stream for heating and cooling the core of the human body.
