Thereby, the far infrared radiation ceramics of this invention are mixed with the product manufactured by resin molding, the new function of far infrared radiation is added, and the added value of the product itself can also be increased.

<Structure of water heater>
Next, the structure of the water heater using the far-infrared radiation ceramics of this invention is demonstrated with reference to FIG. FIG. 1 is a schematic diagram of a water heater using far-infrared radiation ceramics.

  As shown in FIG. 1, the water heater 10 mainly includes an attachment member 20, a pipe 30, a stopper 40, and a ceramic ball 50. The ceramic ball is obtained by forming the far-infrared radiation ceramics of Samples A to C into a ball shape and firing. As the size and shape, a spherical shape having a diameter of 1 mm, 4 mm, 6 mm, 10 mm, and 18 mm, a pellet shape, or the like can be suitably manufactured.

  The ceramic ball 50 is filled in the pipe 30 and both ends of the pipe 30 are closed by stoppers 40. Thereby, it can prevent that the ceramic ball | bowl 50 goes out of a pipe. Further, the attachment member 20 is fixed to both ends of the pipe 30 by sandwiching the stopper 40 from both sides. Thereby, the pipe 30 can be securely fixed from both ends, and the stopper 40 can be prevented from being released and the ceramic ball 50 can be prevented from flowing out.

The stopper 40, the attachment member 20, has a hole for circulating water in the pipe 30, the water flows from the outside through this hole, the inflow water is in contact with the ceramic balls 50 It flows out from the hole on the opposite side

  Fig. 2 and Fig. 3 show examples of construction of water heaters. 2 and 3 are schematic explanatory views showing an example of construction of a water heater. The construction example in FIG. 2 will be described. As shown in FIG. 2, one end of the water heater 10 is connected to a pump 60. The water supplied from the pump flows out of the opposite end of the water heater 10 through the water heater 10 and is discharged to the outside. Here, as shown in FIG. 3, the water heater 10 can be buried in the ground.

<Evaluation>
(1) Far-infrared radiation evaluation The far-infrared radiation characteristics of samples A, B, and C and conventional far-infrared radiation ceramics were evaluated. Conventional far-infrared radiation ceramics are obtained by mixing the following raw materials with the following composition and firing.
Alumina and titania 25wt%
Cordierite 16wt%
(Co-over _{Juraito: 2MgO, 2Al 2 O 3,} 5SiO 2)
Mullite 17wt%
(Mullite: 3MgO, 2Al ₂ O ₃ )
Coagulant 25wt%

  4 to 6 are diagrams showing the infrared radiation characteristics of Samples A, B, and C, respectively. FIG. 7 is a diagram showing the infrared radiation characteristics of conventional far-infrared radiation ceramics. In these drawings, the horizontal axis indicates the emission wavelength (μm), and the vertical axis indicates the emissivity (%).

  As is clear from these figures, samples A, B, and C, which are the far-infrared radiation ceramics of the present invention, are in the near-infrared wavelength range (caused by glaucoma and cataracts) that is not good for the human body. The emission of a wavelength of 3 μm or less is low, and the emission of long-wavelength infrared is higher.

  On the other hand, conventional far-infrared radiation ceramics have high near-infrared radiation of 3 μm or less. As described above, the far-infrared radiation ceramics of the present invention can suppress radiation having a wavelength of 3 μm or less, which is not good for the human body, to a low level.

(2) Choi Komatsuna, Morohaya cultivation evaluation As an example, a sample C mixed with polypropylene resin (referred to as sample C (PP)) was prepared, placed on a polystyrene foam tray, and a tissue paper on it. We prepared soup seeded with shrimp Komatsuna seeds. Similarly, Sample C (PP) was placed on a polystyrene foam tray, and a tissue paper was placed on the tray to seed seeds of Morohaya.

As a comparative example, a tissue paper was placed on a styrofoam tray and seeded with shrimp komatsuna seeds and seeded with moroheiya seeds were prepared. Cultivation was performed in the prepared examples and comparative examples, and the degree of growth was evaluated.
The evaluation results are shown in Tables 2 and 3. Table 2 is a table showing the cultivation evaluation results of Teruna Komatsuna, and Table 3 is a diagram showing the cultivation evaluation results of Morohaya.

  It is the result of having measured the length of the bud which extended for every elapsed days after cultivation in Table 2 and Table 3. From these tables, it is clear that the far-infrared radiation ceramics according to the present invention are used for cultivation, which promotes the growth of the plant as compared with those that do not.

(3) Rice cultivation evaluation As an example, sample C was mixed with polypropylene resin to produce a far-infrared radiation ceramic-containing polypropylene resin (200 mm x 300 mm x thickness 3 mm) formed into a net-like shape, which was then installed in the field to produce rice. went.

  As a comparative example, rice cultivation was performed without setting far infrared radiation ceramic-containing polypropylene resin in the field. Rice cultivation cultivated Koshihikari. The evaluation was carried out by measuring the number of rice grains per bunch and the score using a taste meter.

The evaluation results are shown in Tables 4 and 5. Table 4 is a table showing the number of grains of rice buns for each example and comparative example, and Table 5 shows rice (brown rice) cultivated in the examples and comparative examples with a taste meter. It is the table | surface which showed the score of the result.

  As shown in Table 4, it can be clearly seen that the Example has a larger number of grains of rice bunches. From this, by using the far-infrared radiation ceramics of the present invention, the growth of rice can be enhanced and the yield can be increased.

  Further, as shown in Table 5, the score of the example is two points higher than that of the comparative example. Agricultural workers need to make a great effort to improve their taste. However, the installation of the far-infrared radiation ceramics of the present invention is not necessary for large-scale construction, and the taste can be easily improved by simply performing conventional cultivation.

(4) Evaluation of water heaters A water heater was constructed according to the construction example shown in FIG. 2, and water cultivation was evaluated using this water through the water heater. As usual, the pupae raised their parent seedlings in a pot about 100mm x 100mm in February, and replanted them in the house in mid-September.

  From February to September, the growth degree of the root of the cocoon was compared between a comparative example given normal water and an example given water through a water heater. The results are shown in FIGS. 8 to 10 are photographs of the roots of the examples and comparative examples.

  In each of FIGS. 8 to 9, the left side is a comparative example, and the right side is an example. In FIG. 10, the left side is an example, and the right side is a comparative example. As can be seen from FIG. 8 to FIG. 10, the amount of hair roots was several times larger in the example, and a marked difference in rooting occurred.

Moreover, the first harvesting time was the beginning of November for both the examples and the comparative examples, and there was no difference in the harvesting time. However, the yield up to May was about 5 tons in the comparative example [yield per field (10 ares)], whereas in the example, the yield was nearly 8 tons. . Furthermore, the harvested Example cocoons had better taste (sugar content was 1 to 2 degrees higher) than the comparative example cocoons, and the grades of deterioration and spoilage were significantly different.
From the above, it has been found that the use of a water heater has a great effect on plant cultivation.
