Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a kotatsu top plate.

[0002]

[Prior art]

 In the past, for kotatsu used at home, it was impossible to know whether or not electricity was supplied until the kotatsu futon was rolled up or the position of the knob on the switch was checked. Moreover, it was not known at all whether the temperature of kotatsu was appropriate.

Therefore, if the kotatsu is forgotten while it is energized, there have been health and safety problems for infants and the elderly, and energy saving problems. I was also told that I intended to energize the kotatsu, and after a while, when I entered the kotatsu and stretched out my legs, I felt cold and uncomfortable.

[0004]

[Problems to be solved by the device]

 The present invention is intended to solve the above-mentioned drawbacks, and provides a top plate capable of easily knowing the temperature of kotatsu. In addition, the temperature of the kotatsu changes when the kotatsu is energized for a long time or when it is not energized, so in this case, a top plate that can easily know whether or not the kotatsu is energized is provided. It is also a thing.

[0005]

[Means for Solving the Problems]

 The present invention has been made in view of the above problems of the prior art, and its characteristic feature is that an organic material solution that changes from transparent to cloudy or changes color depending on temperature is applied between a plurality of glass plates. Light control glass sandwiched, or light control glass in which such an organic material solution is sandwiched between films or microencapsulated and adhered to a glass plate, or such organic material solution is microencapsulated and printed on a glass plate The above-mentioned light control glass is used for the surface of the kotatsu top plate, which is a feature of the kotatsu top plate.

As the organic material solution, a solution containing mainly a water-soluble polymer compound or a solution containing mainly a water-soluble polymer compound and a nonionic surfactant can be used.

Further, the temperature range from room temperature to the maximum temperature of the kotatsu top plate when the kotatsu is used is divided into several zones, and an organic material solution that becomes cloudy or changes color in each temperature zone. By appropriately combining the above and using a plurality of glass plates, films or microcapsules, the color pattern of the kotatsu top plate may be changed several times when the temperature of the kotatsu top plate rises or falls.

[0008]

[Action]

 In the kotatsu top plate configured as described above, by energizing the kotatsu, the temperature of the kotatsu continues to rise, the temperature of the kotatsu top plate rises, and the temperature of the light control glass rises. Thus, the organic material solution becomes cloudy or changes color when the temperature of the light control glass rises, while the temperature of the kotatsu gradually decreases when the kotatsu is turned off, and when the temperature drops below a certain temperature after a while When the temperature of the glass drops, it returns to its original transparency or original color.

[0009]

【Example】

 Hereinafter, the present invention will be described based on illustrated embodiments. FIG. 1 shows a perspective view of a kotatsu using a kotatsu top plate 4 to which a light control glass 1 is attached, and FIG. 2 shows an organic material solution 5 that changes from transparent to cloudy or changes color depending on temperature. FIG. 7 is a cross-sectional view of a top plate of Kotatsu in which a light control glass sandwiched between two transparent glass plates 6 and 6 is attached.

FIG. 1 is a perspective view of a kotatsu using a kotatsu top plate 4 in which a light control glass 1 is attached to a kotatsu top plate body 3, and is shown on a kotatsu yagura (not shown). A kotatsu blanket 5 is hung on which the kotatsu top plate 4 of the present invention is placed. Although the organic material solution on the top of the kotatsu is also warmed by the heat generated from the kotatsu, the organic material solution partially becomes cloudy depending on the temperature in that state, but in this example, the temperature is rather low and the distribution temperature is Since they are different, the organic material solution is divided into a cloudy part 2 and other parts due to the temperature rise.

FIG. 2 shows a light control glass 1 in which an organic material solution 5 whose color changes from transparent to cloudy or changes in color depending on temperature is sandwiched between two transparent glass plates 6 and 6 and a main body 3 of a kotatsu plate. FIG. 3 is a cross-sectional view of the Kotatsu top plate 4 attached to FIG. Although not shown, the light control glass 1 is attached to the kotatsu top plate body 3 with an adhesive. Also, in consideration of safety issues, the peripheral portion of the light control glass is covered with a frame or cover material made of a material other than glass such as plastic or wood, or at least the glass plate is covered. The peripheral portion is polished or polished.

In this example, the light control glass is adhered to the main body of the kotatsu with an adhesive, but the present invention is not limited to this example, and the light control glass is fitted to the main body of the kotatsu. It may be included or dropped.

As the organic material solution 6, an organic material solution of a color type whose color reversibly changes with temperature, or a white turbid type organic material solution whose color reversibly changes with white turbidity is used. In this example, the organic material solution 6 is applied by being sandwiched between two glass plates, but the organic material solution 6 may be sandwiched between films or formed into a microfilm to be adhered and formed on the glass plate surface. Good.

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. By the above operation of the present invention, it is possible to obtain a top plate having a functional design in which the color and pattern of the top plate can be changed by turning the power on and off. By doing so, it will greatly contribute to the solution of problems related to safety, health and power saving due to forgetting to turn on / off the power of Kotatsu. Also, by appropriately combining organic material solutions that become cloudy or change color in several temperature zones and use multiple glass plates or films or microcapsules, the kotatsu top plate temperature rises or falls when The functionality of the kotatsu will be enhanced if the pattern on the top plate can be changed several times.

Further, since the light control glass used for the top plate of the kotatsu of the present invention functions by sensing the temperature of the kotatsu as it is as direct heat, the structure is extremely simple, so that it is cost effective. Cheap and advantageous.
