Description

Computer body with negative ion generator {COMPUTER MAIN FRAME WITH ANION GENERATOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer main body having an anion generator, and more particularly, to be mounted on a power supply box of a personal computer main body to collect dust and the like inside the personal computer main body and to discharge air charged with negative ions to the outside. A computer body having an anion generator.

In recent years, with the rapid development of information and communication technology, the time for using personal computer for work or personal is gradually increasing. By the way, the computer is a device that operates by electricity, and since the external parts are sucked by the external air to cool the internal parts and then discharged to the outside, dust is floating around the user, which causes a deterioration of the computer use environment.

On the other hand, negative ions are known to be beneficial to the human body. An anion generator generates a corona discharge between the positive and negative plates by applying a negative voltage of several thousand volts to the negative electrode plate. By being released in the air, the air is anionized. The emitted electrons combine with oxygen molecules to produce anionized oxygen, and the electrons are adsorbed onto the positive electrode plate with negative charge of dust.

However, incorporating a single product of an anion generator into a computer use space is not easy in terms of cost or space, and may also be somewhat cumbersome because the anion generator must be operated separately from the computer.

In view of such various conditions, a technology of adding an anion generator to a computer body is known as Utility Model Registration No. 216994. FIG. 1 is a schematic cross-sectional view for explaining the structure of a computer body having such a conventional anion generator. to be. As shown in FIG. 1, in a computer main body (hereinafter, simply referred to as a “body”) 10 having a conventional negative ion generator, an installation frame 12 provided to install various drivers on a front surface thereof is generally provided. As a result, an anion generator is installed in the installation frame 12. In more detail, the anion generator 20 is mounted on the driver installation frame 12. An inlet 21 is formed at the front of the anion generator 20, and the computer main body 10 at the rear thereof. The exhaust port 22 which discharges the purified air to the space inside is formed.

In front of the exhaust port 22, an anion generator 26 composed of a positive electrode plate 27 and a negative electrode plate 28 is disposed, and a driving fan 24 is mounted in front of the exhaust port 22 again. In the drawing, reference numeral 23 denotes a filter for filtering out dust contained in sucked air.

However, according to the computer body provided with the conventional negative ion generator as described above, since there is a considerable distance between the negative ion generating portion and the cooling fan for discharging the generated negative ions to the outside of the computer main body, the dust collection efficiency inside the computer main body is good. However, there is a problem that the efficiency of negative ion discharge to the outside of the computer body is low.

Furthermore, since a separate driving fan is required in addition to the existing cooling fan, the manufacturing cost and power consumption not only increase, but the noise increases by using two fans. In addition, there is a problem in that the drive installation frame is wasted because it must be mounted in the driver installation frame provided to mount the driver.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and is provided with an anion generator in a power supply box provided in a computer body, thereby eliminating a driver installation frame, and allowing anion discharge efficiency and cost reduction. It is an object to provide a computer body having a.
