FIELD OF THE INVENTION
The present invention is in the field of cooling pillows.
REFERENCE TO RELATED ART
A variety of different cooling pillows have been described in patent publications. For example, an invention that involves the use of a pillow to cool a user's head is CN Pat. No. 205030925 to Xihua University, entitled Built-In Semiconductor Refrigeration Piece Water-Cooling Pillow, having an issue date of Feb. 17, 2016, the disclosure of which is incorporated herein by reference. It is a cooling pillow made in China that has a fan that cools aquogel which cools itself through the radiator on the bottom. It also has two fans on the back side that cool the radiator. It could be loud and aquogel is difficult to find.
A water cooled pillow is described TW patent No. 201225890 to Fu-Jing Cheng, entitled Water-Cooled Pillow Structure, having an issue date of Jul. 1, 2012, the disclosure of which is incorporated herein by reference. The pillow is made of a hard material that dissipates heat. It is made in Taiwan and has a water bag inside that is curved in a wavy shape to provide comfort.
An invention that involves the use of Peltier cooling modules to cool a pillow is US patent No. 20190307270 to Ronald D. Blum and Amitava Gupta, entitled Cooling Pillow, having an issue date of Oct. 10, 2019, the disclosure of which is incorporated herein by reference. With an abandoned patent, this cooling pillow has cubic modules of phase change material close to the surface where the head is placed and uses a Peltier module to cool the strips of phase change material. This looks very uncomfortable and has many figures with cooling strips placed in different areas.
An invention that involves the use of compressed air to cool a pillow is US patent No. 2018014011 to Marc L. Werner, entitled Cooling Pillow, having a publication date of May 24, 2018, the disclosure of which is incorporated herein by reference. This pillow has phase change material and has many holes around the foam that takes in air like a sponge. When compressed, the air inside the pillow cools down the phase change material within the pillow which cools the pillow. This seems impractical as once the pillow loses all of its air, one would have to let it re-inflate itself.
An invention that involves the use of thermoelectric cooling to cool a pillow is U.S. Pat. No. 3,648,469 to James E Chapman, entitled Cooling Pillow, having a publication date of Mar. 14, 1972, the disclosure of which is incorporated herein by reference. This pillow has a radiator in the middle that picks up heat from one side of the pillow and transfers it to the other side. It uses electric current with the Peltier effect in order to transfer the heat. This type of cooling would be quite situational as people who sleep with their arm(s) under their pillow would have warm arms.

The present invention includes a pillow antenna 41 with a wireless Bluetooth connector 40 that connects to any connected device 50 and its connected device antenna 51. A user could monitor his sleep with his connected device 50.
As seen in FIG. 2, the present invention includes a pillowcase 10 that wraps around the foam body 80, which houses the Cooler Module columns. The Cooler Module columns have and optional phase change material pack 20 within an optional phase change material pack casing 30. The Cooler Module columns include a 1st Cooler Module column 110, 2nd Cooler Module column 120, 3rd Cooler Module column 130, 4th Cooler Module column 140, 5th Cooler Module column 150, 6th Cooler Module column 160, 7th Cooler Module column 170, 8th Cooler Module column 180, 9th Cooler Module column 190, and a 10th Cooler Module column 200. Each Cooler Module column contains 5 Cooler Modules. The Cooler Module columns allow The Cooler Modules too be monitored and installed more efficiently. Be face change material pack 20 is installed directly above the Cooler Module columns to absorb the heat of the user over a higher surface area. The phase change material pack casing 30 allows for even distribution of phase change material within the phase change material pack 20.
As seen in FIG. 3, the present invention has a top front side 300, left front edge 301, front right edge 302, top right edge 303, right rear edge 304, bottom right edge 305, bottom opening 306, bottom rear edge 307, bottom left edge 308, front bottom edge 309. The present invention's top front side 300 is directly above the present invention's front bottom edge 309. The invention's left front edge 301 is directly across from the inventions front right edge 302. The bottom opening 306 visually depicts where the Cooler Modules will be installed. The left front edge 301, front right edge 302, and right rear edge 304 are all the same height In order to create an evenly sized pillow for the user. The Peltier cooler board 310 allows the Cooler Modules installed onto it to be stable, therefore optimizing cooling. The present invention's Cooler Modules have a 1st Peltier Cooler 321, 2nd Peltier Cooler 322, 3rd Peltier Cooler 323, 4th Peltier Cooler 324, and a 5th Peltier Cooler 325. The Peltier Coolers use electric current to move heat from the pillow to the bottom side of the Peltier Cooler. The heat from the bottom of the Peltier Coolers is then transferred to the heatsinks groupings. The present invention has a 1st Heatsink Grouping 331, 2nd Heatsink Grouping 332, 3rd Heatsink Grouping 333, 4th Heatsink Grouping 334, and a 5th Heatsink Grouping 335. The heat sink groupings are fitted with liquid tubes 344 that absorb the heat from the heat sink groupings. The liquid tubes carry the heat from the heat sink to an outside radiator that is not shown. This radiator naturally releases heat from itself. The liquid moves throughout the liquid tubes 344 through a liquid pump that is not shown. The liquid cooling provides a quieter way do displace heat from the pillow. The pillow also has an air-cooling option that is faster, but louder than the liquid cooling option. The Cooler Modules use fans placed evenly throughout the Cooler Modules in order to evenly remove heat from the pillow. The hot air is moved out of the pillow through the air conduit 345. The present invention has a 1st fan 336, 2nd fan 337, 3rd fan 338, 4th fan 339, 5th fan 340, 6th fan 341, 7th fan 342, and an 8th fan 343. At the bottom of the Cooler Modules in both types of cooling are ceramic-plated fiberglass bottoms. The present invention has a 1st fiberglass bottom 326, 2nd fiberglass bottom 327, 3rd fiberglass bottom 328, 4th fiberglass bottom 329, 5th fiberglass bottom 330. These fiberglass bottoms provide heat insulation so that the bottom of the pillow does not get too hot. They also help to prevent heat from escaping into the rest of the pillow. The fiberglass bottoms have ceramic tops so that the heat sinks are secure within the Cooler Modules. The ceramic also provides insulation to the cooler module.
As seen in FIG. 4, a Cooler Module has a 1st LED Light Strip 410, and a 2nd LED Light Strip 420. The light strips are connected to a pressure sensor 450. The pressure sensor has a pressure sensor backing 460 for support. The LED light strips are connected to the pressure sensor 450. When the pressure sensor 450 senses a high enough pressure, the LED light strips will either turn off or change colors depending on the user's preference. The pressure sensors 450 also gauge the sleep patterns of the user based on movement. The connected device 50 can be used to change the pattern of the LED Light Strip and set different interactions with the 1st LED Light Strip 410 or the 2nd LED light Strip 420. Under the LED Light Strips and the pressure sensor is the Peltier Cooler. The Peltier Cooler has an upper ceramic substrate 430 and a lower ceramic substrate 440. The ceramic substrates are electrical insulators and keep the current within the Peltier Cooler for as much cooling efficiency as possible. In between the ceramic substrates are Thermoelectric Legs 470. Thermoelectric Legs 470 use electric current to move heat from one side to the other. Below the lower ceramic substrate lies the heatsink groupings 331. These heatsink groupings pull heat from the lower ceramic substrate which can be removed with the liquid tube 344 or the fans 336. Connected below the heatsink is the ceramic top of the fiberglass bottom 326. The fiberglass bottom 326 insulates the bottom of the pillow so that it does heat up.
The present invention cooling pillow can have medical or nonmedical use with liquid or air cooling or a combination of liquid and air cooling.
