Brief Patent Description - Full Patent Description - Patent Application Claims
FIELD OF THE INVENTION [0001] The present invention relates generally to temperature and climate-controlled suits that are worn by humans to protect them from extreme external temperatures in the environment. Specifically, the present invention pertains to low-cost self-contained climate-controlled suits that are worn by humans that keep a person's skin temperature constant without moisture buildup inside the suit. BACKGROUND OF THE INVENTION [0002] In the extreme winter and summer temperatures, it is often uncomfortable, if not difficult, to move about outdoors. Travel is even more difficult in certain parts of the country such as the Arizona desert in summer, or in Minnesota during winter where temperatures can range from 110 degrees to as low as -30 degrees. While most individuals cope in the extreme cold temperatures by wearing layers of clothing in an effort to secure body heat, it would be desirable to have a portable means to provide heat that would reduce the need to wear many layers of clothing. Likewise, in the summer, many professionals are required to wear business suits that are very uncomfortable in high temperatures and high humidity. It would also be desirable to provide a portable means to cool a person who must wear uncomfortable clothing outdoors to maximize comfort. [0003] The present invention addresses these concerns by providing a suit that may be worn over clothing while maintaining a stable temperature and humidity level within a confined space of the suit. The temperature inside the suit may be kept at a constant temperature through the use of a combination thermoelectric heater/cooler that is housed within a backpack. An intake fan is exposed to the elements and ingests air from the outside into the backpack where it passes over a large heat sink that is either cool or hot depending on how the heater/cooler is set. When the air passes over the heat sink, the temperature of the air is either raised or lowered depending on the temperature of the heat sink. The air is then forced out of the backpack into the suit through a narrow tube that his connected to the suit. [0004] The suit is made from plastic, vinyl or other suitable non-porous material. The suit is constructed so that it can cover a large portion of the human body over clothing, yet leave the hands, feet, and face exposed to the environment. When the air is delivered from the backpack to the suit through the tube, it circulates throughout the suit so that the person within the suit remains in a comfortable constant-temperature and low-humidity environment. The air is expelled through openings in the suit near the neck area or around the hands and feet area. DISCUSSION OF THE PRIOR ART [0005] Temperature controlled suits are known in the prior art. More specifically, suits that are used to cover an entire person's body that are cooled or heated using an external source of conditioned air are discussed in the prior art. Other similar temperature-controlled and air conditioned suits are disclosed in U.S. Pat. Nos. 3,064,448, 2,540,547, 3,085,405, 3,085,405, 5,197,294, and French Patent No. FR2619315. [0006] While these devices aim to function as air conditioned suits, and while each invention disclosed in the respective patents may disclose a feature of the present invention, none of the above-listed patents disclose the combination of features in the present invention either individually or in combination with each other in such a way that it would have been obvious to do so at the time the present invention was conceived. [0007] In addition, there is a need in the art for a device which can function as both a thermoelectric air conditioner that works in combination with a lightweight plastic or vinyl suit worn over other clothing that maximizes throughput of air, yet minimizes the level of humidity under the suit. A device of this type is disclosed by the present invention. SUMMARY OF THE INVENTION [0008] Broadly, it is an object of the present invention to provide a source for heating and cooling a space confined under a garment. [0009] It is a further object of the present invention that the source for heating and cooling the space is a thermoelectric heating and cooling unit. [0010] It is a further object of the present invention that the thermoelectric heating and cooling unit be confined within a closed space. [0011] It is a further object of the present invention that a fan or other wind-producing device be used to deliver air in contact with the thermoelectric device to cool or heat the air. [0012] It is a further object of the present invention that the heated or cooled air is delivered through a tube from the closed space to inside of the garment. [0013] It is a further object of the present invention that the garment be worn over at least one layer of clothing that is worn by a person. [0014] It is a further object of the present invention that the thermoelectric device is capable of switching from heating to cooling functionality by means of a switch. [0015] It is a further object of the present invention that the air delivered to the garment contains minimal humidity. [0016] The description of the invention which follows, together with the accompanying drawings should not be construed as limiting the invention to the example shown and described, because those skilled in the art to which this invention appertains will be able to devise other forms thereof within the ambit of the appended claims. BRIEF DESCRIPTION OF THE DRAWINGS [0017] FIG. 1 is a front view of the backpack that encloses the thermoelectric apparatus and the delivery tube; [0018] FIG. 2 is an exploded view of the thermoelectric apparatus from the front of the device; [0019] FIG. 3 is an exploded view of the thermoelectric apparatus from the rear of the device; Continue reading about Air conditioning system for a garment...
