[0010] In the above method, a mixture obtained by mixing food waste, vegetable powder, a biodegradable resin, a foamable member, and a thermosetting resin or a thermoplastic resin is subjected to hollow molding. Therefore, the electric appliance body according to claim 1 can be manufactured by the same molding method as in the case of plastic molding.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an electric appliance body and a method of manufacturing the same according to an embodiment of the present invention will be described. FIG. 1 is a perspective view showing a television body according to the present invention. The TV body 1 is made of a material consisting of food waste, vegetable powder, a biodegradable resin, a thermosetting resin, and a foamable member, using the same molding method as in plastic molding. It is manufactured by molding.

FIG. 2 shows a manufacturing process of the TV body 1.
This will be described with reference to FIG. FIG. 2 is a flowchart showing the manufacturing process. First, okara (vegetable powder) generated during the production of tofu, chitosan (food waste), cellulose (biodegradable resin), a thermosetting resin, and a foamable member are mixed, and heated and mixed. By performing stirring, the above-mentioned okara, chitosan, cellulose, a foamable member, and a thermosetting resin are mixed (S1). Here, this chitosan is a basic polysaccharide widely distributed in organisms such as crustaceans such as crabs and shrimps, and shellfish such as oysters. Things. The temperature at the time of mixing is suitably about 150 degrees. Next, the mixture obtained in the mixing step of S1 is injected into a mold of a desired shape while being heated to a temperature suitable for hollow molding, and gas is injected.
Then, after cooling and solidifying while maintaining the gas pressure so as to obtain a desired shape, the television body 1 is obtained by taking out from the mold (S2).

Here, the results of experiments in which forcible charging is performed on a material (referred to as "Okapak" in FIG. 3) made of okara and biodegradable resin constituting the TV body 1 and polystyrene are shown. In this experiment, a DC corona discharge was applied to a material composed of okara and biodegradable resin and polystyrene using a charge decay measuring device (electrostatic sweep memory KM-511 manufactured by Kasuga Electric Co., Ltd.). And a guideline value immediately before discharge OFF,
The decay time until the pointer value became half was measured.
The measurement conditions were as follows: the distance from the charged electrode to the test surface was 25.
mm, the distance from the measuring device to the test surface was 15 mm, the sample to be measured was sliced to half the thickness, and the sample surface was set to face the electrode side. FIG. 3 is a diagram showing a guideline value immediately before the discharge OFF and a decay time until the guideline value becomes half. According to the experimental data, it can be seen that the decay time for the material consisting of okara and biodegradable resin or the like until the above-mentioned guideline value is reduced to half compared with polystyrene is greatly reduced.

As described above, according to the television body 1 according to one embodiment of the present invention, the same characteristics as those of a plastic product can be obtained in all aspects such as strength and heat resistance. It can be used as a substitute for the synthetic resin used in the above. In addition, since the TV body 1 is mainly made of a material made of okara and a biodegradable resin or the like, as shown in the above experimental data, the electrification of static electricity is suppressed. In addition, the TV body 1
Even when disposed of in landfills, it is decomposed by microorganisms and does not remain in the soil.Even when incinerated, a small amount of energy is required without the need for a high-temperature incinerator as in the case of a conventional plastic TV body. Because it can be incinerated and does not generate harmful gases during incineration, waste does not cause environmental destruction. Further, since the television body 1 includes a foaming member, it is possible to reduce the weight. In the above embodiment, the present invention is described as being applied to a television body, but it is needless to say that the present invention can be applied to other electric appliance bodies.

The present invention is not limited to the configuration of the above embodiment, and various modifications are possible. For example, in the above-described embodiment, as a material constituting the TV body 1, food waste is described as “karato”. However, the material is not necessarily limited thereto, and bran, coffee bean cake, soybean cake,
Any of soy sauce grounds, beer grounds, or a combination thereof may be used. Further, in the above-described embodiment, a thermosetting resin is used as one of the materials constituting the TV body 1, but a thermoplastic resin may be used instead or together with this.

Further, the food waste and the biodegradable resin are not limited to the materials described in the above embodiment. Further, the molding of the television body 1 is performed by hollow molding, but may be performed by other molding methods such as extrusion molding and injection molding. In the above embodiment, the present invention is described as being applied to a television body, but it is needless to say that the present invention can be applied to other electric appliances.

[0017]

As described above, according to the electric appliance body made of food waste or the like according to the first or second aspect of the present invention, it can be molded in the same manner as a conventional plastic product. In all respects, such as strength, heat resistance, etc., characteristics equivalent to plastic products can be obtained. Since the body for electric appliances is mainly made of a material made of okara and a biodegradable resin, the static electricity is less charged than the body for electric appliances made of polystyrene, and the surrounding dust and the like are applied to the body. Adsorption can be eliminated. Further, even if this electric appliance body is disposed of in a landfill or the like, it is decomposed (corroded) by microorganisms in the soil, and does not remain in the soil. In addition, even when this electric appliance body is incinerated, it can be incinerated with a small amount of energy without generating harmful gases. Therefore,
Waste does not cause environmental destruction, and special equipment such as a high-temperature high-temperature incinerator, which was conventionally required for incineration of plastic products, is not required. Further, since the body for an electric appliance includes a foamable member, it is possible to reduce the weight.

According to a third aspect of the present invention, there is provided a method of manufacturing an electric appliance body comprising food waste and the like.
Since a mixture obtained by mixing a predetermined food waste, a biodegradable resin, and a foamable member is molded by hollow molding, the molding method is the same as that of the conventional plastic molding. The body for electrical appliances can be manufactured.
