Description

DISPLAY APPARATUS HAVING A FUNCTION FOR REMOVING DUST}

The present invention relates to a display device having a dust removal function that makes it possible to easily remove dust from the screen by neutralizing the static electricity that causes dust to adhere to the screen.

In general, a device for displaying an image includes a television or LCD monitor using a cathode-ray tube (CRT), a liquid crystal display (LCD), a plasma display panel (PDP), or the like.

Such a display device has had to be periodically cleaned by attaching dust to the screen, and it is not easy to separate dust from the screen due to static electricity.

In order to solve this problem, various apparatuses for cleaning the screen of the display apparatus have been developed, which will be described below with reference to the accompanying drawings.

1 is a perspective view illustrating a screen dust removing apparatus of a projection television according to the related art. As shown, the screen dust removing device according to the prior art is a patent application No. 2003-0089770 filed by the applicant to the Korean Intellectual Property Office, the large screen 20 is installed on the front of the cabinet 10, the cabinet A projection television having a rear cover (30) mounted on a rear surface of (10), comprising a guide hole formed at an upper end of a cabinet (10), the cabinet being fixedly installed at both sides of the cabinet (10) and having a front guide groove formed therein. Guide part; A rear cover guide part connected to the cabinet guide part and fixedly installed at both sides of the rear cover 30 and having a rear guide groove; A guide shaft sliding along the front guide groove and the rear guide groove; A screen protection cover 70 whose one end is wound around the guide shaft through the guide hole; And a screen protection cover 70 fixedly installed at the other end of the screen protection cover 70 so as to be movable upward and downward toward the front of the screen 20, and on one surface thereof, a dust removal member 82 capable of removing dust from the screen 20. ) Is formed an operating tool (80).

As described above, the screen dust removing apparatus of the projection television according to the prior art is not only to damage the appearance due to the installation of the screen protective cover and the operation port, but also to be inconvenient for removing dust, and only by the dust removing member. There was a problem that there is a limit to properly remove the dust attached.

The present invention has been made to solve the above problems, and by neutralizing the static electricity that causes the dust attached to the screen, it is possible to easily remove the dust from the screen, furthermore, by discharging the clean air from which the dust is removed Clean up the environment.

In the display device having a dust removing function according to the present invention, in the display device provided with a screen in the main body, an ion emitting part for removing dust attached to the screen by neutralizing charged static electricity by releasing ions is installed around the screen. It features.

The present invention makes it easy to remove dust from the screen by neutralizing the static electricity that causes the dust to adhere to the screen, and furthermore, by cleaning the dust removed from the screen by the neutralization of the static electricity with air to remove the dust By releasing air, it has the effect of purifying the surrounding environment.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

2 is a perspective view showing a display device having a dust removal function according to the present invention, Figure 3 is a block diagram showing a display device having a dust removal function according to the present invention. As shown, the display apparatus 100 having a dust removing function according to the present invention is provided with a screen 120 for displaying an image on the front of the main body 110, the ion emitter 130 around the screen 120 ) Is installed.

Meanwhile, the display apparatus 100 having a dust removing function according to the present invention may be applied to various display apparatuses for displaying an image such as an LCD, a PDP television, an LCD monitor, or the like.

The ion emitter 130 dissipates the static electricity to attach dust to the screen 120 by releasing ions to neutralize the charged static electricity so that the dust is removed from the screen 120.

The ion emitter 130 is provided with an electrode (not shown) to receive power, and generates ions by the supplied power. For example, the ion emitter 130 may be applied to ionization by a high voltage raised by an ion conversion transformer (not shown). The current is relatively lowered by the increase of the voltage according to the ampere law, and this high voltage causes ionization to air molecules to generate ions.

Meanwhile, the ion emitter 130 includes first and second ion emitters 131 and 132 which emit negative and negative ions, respectively, in order to neutralize them, considering that the static electricity that causes dust to attach is positive or negative.

The first and second ion emitters 131 and 132 are composed of a plurality of anions and cations so as to be uniformly supplied on the screen 120, and are alternately installed around the screen 120. For example, the first and second ion emitters 131 and 132 are discharged. The parts 131 and 132 are installed to be alternately arranged up and down so as to be adjacent to both sides of the screen 120 in the main body 110.

On the other hand, when the first and second ion emitters 131 and 132 operate simultaneously, the control unit 140 receives an operation signal by the operation switch 141 to prevent the neutralization of the static electricity due to the combination of negative ions and positive ions. It is preferable to alternately operate the first and second ion emitters 131 and 132 for a predetermined time.

As shown in FIG. 4, the display apparatus 100 having a dust removing function according to the present invention is formed to be arranged along the width direction at an end 111 positioned below the screen 120 in the main body 110. A plurality of suction ports 151, a suction path 152 formed inside the main body 110 so as to be connected to the discharge port 112 at the rear side of the main body 110 from the suction port 151, and dust and dirt through the suction path 152. It may further include a cleaning fan 153 installed on the suction path 152 to suction the air, and a filter 154 installed on the outlet side of the suction path 152 to filter dust from the air. . Therefore, the dust falling down from the screen 120 by the ion emitter 130 is sucked together with the air to discharge the clean air from which the dust is removed by filtering.

Referring to the operation of the display device having a dust removal function according to the present invention having such a configuration as follows.

When the operation switch 141 is turned on to remove dust attached to the screen 120 by static electricity, the control unit 140 causes the anion and the positive ion to be discharged from the first and second ion emitting units 131 and 132 for a predetermined time. Release each of these alternately. By neutralizing the static electricity charged on the screen 120 by the ions emitted from the first and second ion emitters 131 and 132, the dust is easily separated from the screen 120.

At this time, clean air from which dust is removed by the filter 154 by suctioning the dust falling from the screen 120 by the driving of the cleaning fan 153 through the air inlet 151 together with the air is the main body 110. It is to be discharged through the rear outlet 112.

According to the preferred embodiment of the present invention as described above, it is possible to easily remove the dust from the screen by neutralizing the static electricity that causes the dust to adhere to the screen, and furthermore, the dust falling from the screen by the neutralization of the static electricity and air It cleans up the surroundings by inhaling together and releasing the dust from which the dust is removed.

As described above, specific embodiments have been described in the detailed description of the present invention, but it is obvious that the technology of the present invention can be easily modified by those skilled in the art, and such modified embodiments are defined in the claims of the present invention. It will be included in the technical spirit described.
