  Cooling sheet for pillowUSPTO Application #: 20070261414Title: Cooling sheet for pillow Abstract: A cooling sheet for pillow includes a plurality of thermoelectric coolers, a thermal pad, and a heat sink. The thermoelectric coolers are electrically connected one another in series, with a first junction and a second junction. The thermal pad is thermally connected to the first junction of the thermoelectric coolers. The heat sink is thermally connected to the second junction of the thermoelectric coolers. The thermal pad is adapted to be used with a pillow, and the temperature of the thermal pad is controlled by the thermoelectric coolers. The thermoelectric coolers include first and second metals that are dissimilar from the first metal. The first and second metals are connected to each other at two junctions forming Peltier junctions. The thermoelectric coolers further include an EMF source for providing electric current through the Peltier junctions. The thermoelectric coolers can be realized by two dissimilar semiconductors.

Agent: Park Law Firm - Los Angeles, CA, US Inventor: Jacob H. Polder USPTO Applicaton #: 20070261414 - Class: 062003500 (USPTO) Related Patent Categories: Refrigeration, Using Electrical Or Magnetic Effect, Thermoelectric; E.g., Peltier Effect, Made With Flexible Heat Exchanger Material; E.g., Blanket, Wearing Apparel, Etc. The Patent Description & Claims data below is from USPTO Patent Application 20070261414. Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] The present invention relates to a cooling sheet for pillow. [0002] More particularly, this invention relates to a cooling sheet that controls the temperature of the pillow. [0003] Still more specifically, the invention relates a cooling sheet using Peltier effects. [0004] Sleeping is an important and complicated biological process people go through almost ritually every night. [0005] Sound and good sleep does not come easily to some people. There are many special ways to lead to a good-night sleep, which are resulted from the psychological or elctrophysiological researches. [0006] In contrast, there are also common-sense wisdoms. For example, a cozy and comfortable bedroom might be a good starting. Sometimes and for some people, a delicate sectional control of temperature of their body is one of the necessary conditions for a good sleep; cool head or warm feet. [0007] Accordingly, a need for a cooling sheet for pillow has been present for a long time. This invention is directed to solve these problems and satisfy the long-felt need. SUMMARY OF THE INVENTION [0008] The present invention contrives to solve the disadvantages of the prior art. [0009] An object of the invention is to provide a cooling sheet for pillow. [0010] Another object of the invention is to provide a cooling sheet that cools the pillow. [0011] Still another object of the invention is to provide a cooling sheet using a thermoelectric coolers operated by the Peltier effect. [0012] A cooling sheet for pillow includes a plurality of thermoelectric coolers, a thermal pad, and a heat sink cooled by a cooling fan. [0013] The thermoelectric coolers are electrically connected one another in series or in parallel, with a first junction and a second junction. [0014] The thermal pad is thermally connected to the first junction of the thermoelectric coolers. [0015] The heat sink is thermally connected to the second junction of the thermoelectric coolers. [0016] The thermal pad is adapted to be used with a pillow, and the temperature of the thermal pad is controlled by the thermoelectric coolers. [0017] The thermoelectric coolers include a first metal and a second metal that is dissimilar from the first metal. [0018] The first metal and the second metal are connected to each other at two junctions forming Peltier junctions. [0019] The thermoelectric coolers further include an EMF source for providing electric current through the Peltier junctions. [0020] The second metal includes a primary second metal and a secondary second metal, and the EMF source is inserted in between the primary and secondary second metals. [0021] The first junction, which is connected to the thermal pad, is a cooling junction. [0022] Alternatively, the thermoelectric coolers may include a first semiconductor and a second semiconductor that is dissimilar from the first semiconductor. The first semiconductor and the second semiconductor are connected to each other at two junctions forming Peltier junctions. Continue reading...
