Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat having a heating function.

[0002]

2. Description of the Related Art Conventionally, a toilet seat having a heater built into a toilet seat body has been used. With such a toilet seat, it is possible to prevent the buttocks and the back of the thigh from being cold even when the toilet is used even in winter.

[0003]

However, with the above-described toilet seat, only the buttocks and the back of the thigh of the human body can be heated, which is insufficient as a heating device. Further, the heating function for heating the main body of the toilet seat is necessary only in winter, and the heater is wasted at other times.

Further, in the above-described toilet seat, it takes some time for the toilet seat body to warm up after a person enters the toilet. Therefore, there was a problem that the user had to sit on a cold toilet seat immediately after entering the toilet.

Therefore, an object of the present invention is to provide a toilet seat which can effectively warm the human body and can be used for promoting health throughout the year. Another object of the present invention is to provide a toilet seat that can effectively warm the human body, can be used for promoting health throughout the year, and can be used in a warm condition at all times.

[0006]

A toilet seat according to the present invention is a toilet seat in which a toilet seat lid is openably and closably attached to a toilet seat body, and a sheet heating element for radiating far infrared rays is attached to the toilet seat lid. An energizing means for energizing the device is provided. In particular, it is preferable that the sheet heating element is made of carbon fiber mixed paper.

Further, when the toilet seat lid is open, the sheet heating element is set to the first temperature for keeping the human body warm, and when the toilet seat lid is closed, the sheet heating element is set to keep the toilet seat body warm. A temperature switching means for setting the second temperature for the purpose may be further provided.

[0008]

In the toilet seat according to the present invention, far infrared rays are radiated forward from the heating surface of the sheet heating element when the sheet heating element is energized by the energizing means while a person is sitting on the toilet seat body. The radiant energy of the far infrared rays goes straight to reach the waist and back of the human body and activates the molecular motion inside the human body. As a result, the waist and back are effectively warmed.

As described above, since far infrared rays directly apply heat energy to the human body without passing through the air, the human body can be warmed efficiently and quickly. Therefore, in this toilet seat, a sufficient heating function can be obtained with low power consumption. Moreover, since far-infrared rays can effectively warm the waist and back from the inside, it can be used as a thermotherapy device throughout the year and contributes to health promotion.

When the sheet heating element is energized by the energizing means with the toilet seat lid closed, far infrared rays are radiated from the sheet heating element, and the radiant energy of the far infrared rays reaches the toilet seat body. As a result, the toilet seat body is kept warm. In this case, the toilet seat body can be kept warm with a small amount of power consumption.

In particular, when carbon fiber mixed paper is used as the sheet heating element, far infrared rays having a wavelength most easily absorbed by the human body and clothes can be efficiently radiated, so that the heating temperature is low and the power consumption is low. Can effectively warm the human body.

Further, when the temperature switching means is provided,
The sheet heating element is set to the first temperature for keeping the human body warm when the toilet seat lid is open, and the sheet heating element is set to the second temperature for keeping the toilet seat body warm when the toilet seat lid is closed. Set to temperature. As a result, the functions of the thermotherapy device and the heating device and the function of keeping the heat of the toilet seat body are efficiently and automatically switched. Since a high temperature is not required to keep the toilet seat body warm, wasteful power consumption can be prevented by setting the second temperature lower than the first temperature.

The far-infrared radiation sheet 50 includes a carbon fiber mixed paper 100 and resin layers 101 and 102 laminated on both sides of the carbon fiber mixed paper 100. The resin layers 101 and 102 are formed of, for example, glass fiber reinforced epoxy resin (hereinafter referred to as glass epoxy resin) or FRP. This far infrared radiation sheet 50
Is manufactured as follows.

Water is added to bast fibers such as Kozo, Mitsumata, or Gunpi, which are raw materials for Japanese paper, to make a pulp liquid, and carbon fibers cut to a predetermined size, for example, about 5 mm are mixed therein and dispersed. Let The pulp solution is flowed on a papermaking net to form a wet sheet. The wet sheet is mechanically squeezed using a squeezing roll, dried, and then cut into predetermined dimensions. Thus, the carbon fiber mixed paper 1 having a thickness of about 0.1 mm
00 is formed.

Then, on the surface of the carbon fiber mixed paper 100, a silver paste 104 is printed in a strip shape having a width of about 1 cm along two opposite sides, and a copper paste coated with a conductive adhesive is applied to the silver paste 104. The foil tape 103 is attached. In this way, a pair of electrodes is formed at the edge of the carbon fiber mixed paper 100.

Further, for example, the carbon fiber mixed paper 100 is sandwiched between resins in a raw dry state and hot pressed to heat-cure the resin. At this time, as shown in FIG. 5, a hole for attaching a conductive wire is formed in the resin in the end region of each copper foil tape 103. In this way, the resin layers 101 and 102 are laminated on both sides of the carbon fiber mixed paper 100. Finally, the conductor wire 105 is connected to one end of each copper foil tape 103 by soldering or the like. In this way, the far infrared radiation sheet 50 having a thickness of about 0.5 mm is manufactured. The far-infrared radiation sheet 50 is lightweight and flexible.

The resin layers 101 and 102 are provided for imparting insulation and waterproofness to the surface of the carbon fiber mixed paper 100 and for molding the carbon fiber mixed paper 100 into a sheet shape. As the material of the layers 101 and 102, various materials having such a function can be used. Further, a resin layer 101,
Instead of hot pressing 102, carbon fiber mixed paper 10
A resin having an insulating property and a waterproof property may be applied or sprayed on the surface of the zero. A fabric sheet may be attached to one or both surfaces of the far-infrared radiation sheet 50.

Far-infrared radiation sheet 5 through conductor 105
When a voltage is applied to the pair of 0 copper foil tapes 103, an electric current flows through the carbon fibers dispersed in the carbon fiber mixed paper 100, and the carbon fibers generate heat to generate the carbon fiber mixed paper 100.
Far-infrared rays are radiated forward from both sides.

The amount of heat generation and the set temperature of the far infrared radiation sheet 50 are adjusted by the amount of carbon fibers mixed in the carbon fiber mixed paper 100 and the amount of current or applied voltage. Far-infrared rays emitted from the far-infrared ray radiating sheet 50 made of the carbon fiber mixed paper 100 can directly give thermal energy to the inside of the human body with little intervening air. Therefore, this far infrared radiation sheet 5
When 0 is used, the human body part can be warmed quickly and efficiently. Further, since far infrared rays similar to the sun are efficiently radiated, the human body can be comfortably warmed.
