ABSTRACT:
TECHNICAL FIELD
The present invention relates to an electron-emitting device used for manufacturing electron-charged water, counteracting and removing chemical substances, or increasing an anion concentration in air, as well as an electrode used in the electron-emitting device.
BACKGROUND ART
An electron-emitting device has been utilized for manufacturing electron-charged water which is used as drinking water, processed water, cooking water, bath water or the like for businesses such as processed food manufacturers, supermarkets and hotels and for households. The device has also been used for the purposes of counteracting and removing chemical substances contained in food, materials for processed food, livestock feed or the like as well as adding anions to air.
Some examples of the above-described electron-emitting devices have been disclosed in Unexamined Japanese Patent Publication Nos. H5-137804, H7-204656 and H9-94581. An electron-emitting electrode connected with an output terminal of the electron-emitting device is submerged in water in a water tank or a bathtub and is charged with high electric potential, thereby generating electron-charged water.
In a method of manufacturing electron-charged water disclosed in Unexamined Japanese Publication No. H5-137804, a potential treatment device which takes out negative electrons having a specific waveform from an AC100V commercial power supply is used as an electron-emitting device for producing electron-charged water. The electron-emitting device, however, cannot generate current of more than 0.1 mA, and the charged potential is extremely low.
Therefore, there is substantially no effect of potential, which makes it difficult to efficiently manufacture electron-charged water.
An electron-emitting device used in a device for manufacturing electron-charged water disclosed in Unexamined Japanese Publication No. H7-204656 is a potential treatment device or an inverter. The electron-emitting device can generate an alternating or a pulsating current at a frequency of 5,000 to 500,000 Hz and a voltage of 1 to 100V. However, since the frequency range is too wide, it is difficult to select and fix an optimum frequency for efficiently manufacturing electron-charged water. Thus, if the selected frequency is wrong, it may take a long time to manufacture electron-charged water.
In a method of manufacturing electron-charged water disclosed in Unexamined Japanese Patent Publication No. H9-94581, a device which generates high-voltage AC static potential at a frequency of 50/60 Hz and a voltage of 500 to 60,000V is employed as an electron-emitting device. The device, however, needs to have a large-scaled insulation structure in order to prevent electric leakage and for safety because the device generates a high voltage of 500 to 60,000V.
A conventional electron-emitting electrode which is used in combination with an electron-emitting device for manufacturing electron-charged water has such a structure that a metal alligator clip is provided on an end of a copper wire connected to an electron-emitting device. A tank, a table, a bathtub, or the like, where an object to be processed such as drinking water, food and bath water are placed, are electrically insulated from earth using an insulating material such as an insulator, and a metal member clamped by an alligator clip is submerged in water or the object to be processed is clamped by an alligator clip, thereby charging the electrode with a potential.
When adding anions to air in a room, a metal electrode electrically insulated with an insulating material such as an insulator, is hung from a ceiling or on a wall and clamped by an alligator clip provided on an end of a copper wire which is connected to an electron-emitting device.
According to the above methods, however, an object has to be kept insulated from earth, a ceiling or the like. Therefore, the system is complicated and large-scaled and requires remodeling to secure a space for installation. Thus, such methods cannot be easily implemented and remain inconvenient.
To solve the above problems, the other techniques for manufacturing electron-charged water are disclosed in Unexamined Japanese Patent Publications Nos. H5-137804, H7-204656 and H9-94581.
In a method for manufacturing electron-charged water disclosed in Unexamined Japanese Patent Publication No. H5-137804, it is not necessary to keep a bathtub itself insulated. However, water in a bathtub needs to be kept insulated using a pad, sheet or the like made of nonconductive material, which causes problems in practice. Furthermore, since it is substantially impossible to completely insulate water in a bathtub, electrical leakage may occur.
A method of manufacturing electron-charged water disclosed in Unexamined Japanese Patent Publication No. H7-204656 does not need any insulators. In this case, however, water in a non-insulated vessel is directly charged with potential, presenting the possibility of electrical leakage.
According to a method of manufacturing electron-charged water disclosed in Unexamined Japanese Patent Publication No. H9-94581, a water vessel need not be kept insulated by use of a stainless steel electron radiation electrode coated with electric insulating resin. Nevertheless, compared with a non-coated stainless steel electron radiation electrode, the stainless steel electron radiation electrode, because it is covered with insulating resin, has low electron radiating function, which tends to require a longer time to manufacture electrically-processed water.
In view of the above, an object of the present invention is to provide an electron-emitting device having high safety and endurance which can negatively charge and activate an object to be processed efficiently, and an electrode for an electron-emitting device which is safe and can negatively charge and activate an object to be processed efficiently without requiring insulation of an object to be processed, a vessel or the like.
SUMMARY
The electron-emitting device of the present invention is a device comprising a primary coil and a secondary coil wound on an I-core, an E-core combined with the I-core, and a single output terminal extended from one end of the secondary coil. By this structure, high potential is generated by adding an electric field of the secondary coil around a magnetic field of the I-core, and high electrostatic potential is obtained by employing only one output terminal as a single output terminal from two output terminals of the secondary coil. Thus, an object to be processed can be negatively charged and activated efficiently while enhancing safety.
In the above electron-emitting device, the secondary coil is divided into two sections and wound on plural parts on the I-core so that potential of the secondary coil is efficiently increased, thereby providing higher electrostatic potential.
A leakage path iron core which is coated with insulating material is provided between the primary coil and the secondary coil. In the case that the device is damaged, the leakage path iron core functions as electrical resistance so as to check an increase of current flowing to the secondary coil, which further enhances safety.
The E-core is provided so as to surround the I-core, the primary core and the secondary core. By this structure, the magnetic field becomes stable, thereby limiting fluctuation of the potential. Further, if an insulating gap is formed between the secondary coil and the E-core, troubles such as damage in an internal insulation can be prevented.
In the electron-emitting device, alternating current generated in an output terminal is adjustable within a range from 3,000V to 15,000V. Thus, an optimum current can be fixed depending on a capacity, form and characteristic of a load or an object to be processed, and the object can be charged with the most efficient electrostatic potential.
An electrode for an electron-emitting device of the present invention comprises a plurality of bottom-closed cylindrical members in which at least one of the bottom-closed cylindrical members is made of insula
