Description

Cold bed using Peltier's Effect {COLDNESS AND WARMTH BED USING PELTIER'S EFFECT}

The present invention relates to a cold bed using Peltier's Effect. Techniques have been developed to allow hot water to circulate into the mattress (i) or to allow heating beds (ii) to be used to keep the bed warm. It was also developed to make the mattress in the form of a tube and to use cold or hot water in it. However, it is considered that one bed has not been developed so that the upper surface of the bed can be cold or warm, and this operation can be easily performed. It is natural for humans to be active during the day and go to bed at night. When you go to sleep during the day, you feel a little hotter than normal because you have a lot of calories. Therefore, when you fall asleep, it is better to lower your elevated body temperature slightly. After that, when the body temperature is gradually lowered to sleep, the phenomenon occurs that is slightly lower than the normal body temperature at dawn. In addition, since the temperature of the atmosphere is also the lowest at dawn, it is easy to catch a cold, so it is desirable to raise the temperature of the bed slightly at this point. By the way, the bed of the above-mentioned (i) and (ii) type has the function to increase the body temperature but does not have the function to lower the body temperature, and it is inconvenient to use and there is a risk of fire. have. And in case of (iii), a large amount of water is put into the tube and the exhaust is very inconvenient and there is a high possibility of damaging the tube, and it is not possible to effectively control the body temperature.

Therefore, the present invention provides a cold and hot bed that can be conveniently used so that the upper surface (metal plate) of the bed is cold or warm by a simple operation due to its simple structure and almost no failure. In another aspect, the present invention provides a cold bed hot or cold wind is emitted to the upper surface of the bed. All of the cold and hot beds are characterized by using a Peltier element. To this end, the present invention, a cold-temperature device consisting of a Peltier element and a metal plate on which the Peltier element is fixed, a cooling water tank and a fan motor for cooling the Peltier element, a blower, and an air cylinder into which outside air is introduced; And a housing that supports the cold temperature device.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that in the following description, only parts necessary for understanding the present invention are described, and descriptions of other parts will be omitted so as not to obscure the subject matter of the present invention.

In each embodiment of the present invention, the metal plate is mounted on the housing 10. In the housing, a cold and hot device is installed. The cold and hot device of the present invention is divided into six embodiments, where a partial structural change, a change in material, and a change in the number of parts are within the scope of the present invention. On the other hand, the Peltier device is a plate-shaped semiconductor invented by Peltier, a Frenchman in the 19th century. When DC power is supplied thereto, one side generates heat and the other side becomes cold. In addition, if the pole of the power source is different, the side where the heat is generated becomes cold, and the side where the cold side has heat is generated. Therefore, the cold device of the present invention also uses a Peltier device having the above properties.

First, a first embodiment of the present invention will be described. In FIG. 1, the radiator 29 and the water pump 30 are installed outdoors. And the cold device 20 is mounted in the housing 10. When DC power is applied to the Peltier element 22 through the wire 23, the surface in contact with the metal plate 21 is cooled, and thus the body part in contact with the metal plate is cool. At this time, the Peltier device generates heat on the opposite side of the metal plate, and the Peltier device needs to be dissipated (cooled) because the cooling effect of the Peltier device becomes smooth. To this end, cooling water reservoirs 24 are fixed to the bottom of the Peltier element, respectively. In addition, hoses 28 and 27 are connected to the water pump and the radiator in parallel (see FIG. 1A). Therefore, by the action of the water pump, the cooling water circulates into the cooling water tank to cool the Peltier element.

Next, look at the second embodiment shown in FIG. Compared with the first embodiment, this is air-cooled using a pen motor without using a cooling water container. That is, the metal plate 21a is cooled by the Peltier element 22a, and the heat generated in the Peltier element is cooled by the fan motor 25a, and the hot air generated at this time is discharged through the hole 11 of the housing. Reference numeral 23a denotes an electric wire, and 26a denotes a cooling fin.

Next, the third embodiment will be described. Compared with the second embodiment, the fan motor 40 and the air cylinder 24a fixed to the bottom of the Peltier element are used instead of the fan motor. The metal plate 21b is cooled by the action of the Peltier element 22b. At this time, the heat generated in the Peltier element is naturally dissipated by the atmosphere and cooled by external cold air supplied from the blower. That is, the air from the blower is supplied into one of the reservoirs through the tube 41, and the air cools the Peltier element, and is again supplied into the other reservoir through the tube 41a to cool the Peltier element and then the tube 42a Through the outside. Reference numeral 23b denotes an electric wire, and 26b denotes a cooling fin.

Next, a fourth embodiment of the present invention will be described. This is a modification of the first embodiment, in which the human body is not in contact with the metal plate 21c, but in a manner in which cold air and the metal plate are in contact with the human body. That is, the metal plate 21c is cooled by the Peltier element 22c, and the heat generated in the Peltier element is cooled by the radiator 29c, the water pump 30c, and the hoses 28c and 27c. Cooling fins 50c are fixed to the upper surface of the metal plate 21c, and a metal plate 60c having a plurality of holes 61c formed thereon is mounted thereon. The cold air supplied from the blower 40b installed at the outside enters the space portion between the metal plate 21c and the metal plate 60c through the tube 41b. Therefore, external air collides with the cooling plate and the metal plate cooled by the Peltier element, which is immediately released through the hole 61c toward the human body.

Next, a fifth embodiment of the present invention will be described. This corresponds to the composite type of the second and fourth embodiments. That is, the metal plate 21d to which the cooling fin 50d is fixed by the Peltier element 22d is cooled, and the heat generated in the Peltier element in which the cooling fin 26d is formed is discharged through the hole 11d of the housing by the fan motor 25d. The cold air supplied from the blower 40c installed outside enters the space portion between the metal plate 21d and the metal plate 60d through the tube 41c. Therefore, external air collides with the cooling plate and the metal plate cooled by the Peltier element, which is immediately released through the hole 61d toward the human body.

Next, a sixth embodiment of the present invention will be described. This corresponds to the hybrid of the third and fifth embodiments of the present invention. That is, the metal plate 21e is cooled by the Peltier element 22e, and the heat generated in the Peltier element is naturally dissipated by the temperature of the atmosphere, and is cooled by supplying external cool air supplied from the blower 40e into the air chamber 24e. The outside air supplied from the blower enters the space portion between the rapid plate 21e and the metal plate 60e through the tube 41e, and the air collides with the metal plate 21e and the cooling fin 50e to cool down and is discharged toward the human body through the hole 61e. Reference numerals 43e and 44e are tubular bodies and 26e are cooling fins.

As described above, the present invention cools the Peltier device by using a coolant or a fan motor and external air, and serves to cool the user's body through a metal plate or a metal plate formed with holes.

In each of the embodiments of the present invention, the metal plate, the cooling water container, and the air container are preferably selected from materials having a good thermal conductivity such as aluminum or brass, and in the case of the metal plates 60c, 60d, and 60e, the metal, plastic, wood, and other elasticity are excellent. Good materials may be used as the material. In the present invention, the technology for applying power to the Peltier element, fan motor, radiator, water pump, and blower, and the electric technology for manipulating them are not particularly described. In addition, since the technology for installing the cold and hot devices of the present invention is not special, detailed description thereof will be omitted. The present invention as described above can be used to cool in the summer and warm in the winter, which is very convenient because it is made simply by reverse the polar direction of the power applied to the Peltier element.

Of course, the cooling action of the Peltier element is unnecessary when used for the winter season. In addition, the present invention may be configured to automatically operate the cold and hot devices when the user is lying on the bed and stop the operation when coming down from the bed. In the case of the metal plates 21, 21a, 21b, 60c, 60d, and 60e, gold, silver, and the like, which are useful for the human body as well as the metal, may be plated in the material, and ceramics, jade, Stones, wood, paper, etc. may be bonded together.
