Description

Display device with negative ion generator

The present invention relates to a display device having an anion generating device, and more particularly to a display device having an anion generating device in which the transfer of negative ions can be controlled using the force of Lorentz.

In general, it is known that cations present in the air are harmful to the human body while anions are beneficial to the human body. Therefore, attempts have been made to create a pleasant environment by artificially producing negative ions and spinning them into the air. There have also been various studies on how to transfer negative ions generated at one location to another.

Meanwhile, a method of organically combining anion generator with a display device has been studied. This is because the user may be damaged by harmful factors such as electromagnetic waves in the environment in which the display device is used to actively improve this. In other words, while devising a passive damage reduction method while creating a beneficial environment for the user.

Conventional negative ion generating systems did not have sufficient amount of negative ions to be delivered to the user and moreover could not freely control the delivery distance of negative ions. In other words, negative ions are generated by corona or arc discharge, and the negative ions are then blown to a user using a fan. However, this method had the following problems.

First, when generating negative ions by corona or arc discharge, in addition to the desired negative ions, harmful components such as ozone may be generated at the same time. Therefore, these harmful components were very likely to be delivered to the user by the fan's blowing power. In addition, since the fan is used to deliver the generated negative ions to the user, there is a disadvantage in that the negative ions cannot be properly delivered to the user far from the point where the negative ion generating device is located. That is, the delivery distance of the anion could not be freely adjusted.

The present invention has been made to solve the above problems, it is an object of the present invention to provide a display device having an improved anion generating device.

It is an object of the present invention to provide a display device with an anion generating device, in which the delivery distance of generated anions can be controlled.

It is an object of the present invention to provide a display device having an anion generator, in which the inflow and delivery of anions can be made appropriately.

In order to achieve the above object, according to the present invention, an anion generating material applied to the surface of the funnel of the cathode ray tube, a bottom suction inlet capable of sucking negative ions generated from the anion generating material and a front room capable of emitting anions to the outside A display device is provided having a transfer case having an outlet and a first electromagnet provided on opposite sides of the transfer case to form a predetermined magnetic field in the transfer case.

According to one feature of the invention, the voltage applied to the first electromagnet can be varied to vary the intensity of the magnetic field formed in the transfer case.

According to another feature of the invention, the anion generating material is a composition of silicon, zirconium, aluminum, cerium, lanthanum, magnesium, calcium.

According to another feature of the invention, the anion generating material is applied to the surface of the funnel in a slurry state.

According to another feature of the present invention, an inflow case curved with a predetermined curvature having a top opening corresponding to a bottom surface of the transfer case and a bottom opening facing the funnel surface of the cathode ray tube, and a curved surface of the inflow case It further comprises a plurality of second electromagnets installed in an aligned state opposite to the.

According to another feature of the invention, the voltage applied to the second electromagnet is set differently according to the installation position of the second electromagnet so that the negative ions passing through the inflow case can be advanced upward.

Hereinafter, the present invention will be described in more detail with reference to an embodiment shown in the accompanying drawings.

Prior to referring to the figures, it is generally known that electrons or charged particles incident perpendicular to the magnetic field are forced by the Fleming's left-hand law in a direction perpendicular to them, thus making constant circular motions. . In addition, when the electron is obliquely incident to the direction of the magnetic field at an angle of θ, only the components of the motion perpendicular to the magnetic field are forced in the directions perpendicular to each other, and are combined with the horizontal components to perform a kind of spiral motion. In this case, the radius of motion of the circularly moving particles is inversely proportional to the strength of the magnetic field and proportional to the incident velocity, which is called 'Lorentz Force'. As a result, the position and distance of the delivered particles can be freely controlled by controlling the movement of the charged particles (ions) according to the particle incident speed and the magnetic field strength. In the present invention, the negative ions generated in the negative ion generating device included in the display device can be delivered without loss to the user by the force of Lorentz described above.

1 is a perspective view of a portion of the display device cut away to expose the negative ion generating device according to the present invention.

Referring to the drawings, the display device 10 using the cathode ray tube is surrounded by the front case 11 and the rear case 12. A cathode ray tube is installed inside the case, and the panel 14 of the cathode ray tube is exposed on the front surface of the display device 10. A pedestal 13 is installed on the bottom of the case. The inflow transfer part 20 of the negative ion generating device is installed close to the front case 11 inside the case. The inlet delivery unit 20 of the negative ion generating device is a cathode ray tube at the top center of the front case 11 so that the anion transferred from the inlet delivery unit 20 of the negative ion generating device is suitable for delivery to the user who is looking at the display device. It is preferable to be installed at the top of the.

FIG. 2 is a schematic perspective side view of the display device shown in FIG. 1.

Referring to the drawings, the cathode ray tube installed inside the case includes a panel 14 and a funnel 15 sealed to the panel 14 and having a neck 16 integrally formed thereon. Anion generating material 17 is applied to the surface of the funnel 15. The negative ion generating material 17 is a component of the negative ion generating device, and generates negative ions when the display device is operated. (In fact, negative ions are generated even when the display device is not operated.) The negative ions generated from the negative ion generating material 17 may be discharged to the outside through the inlet transfer unit 20.

The anion generating material 17 is a ceramic material, for example, and main components are silicon (Si), zirconium (Zr), cerium (Ce), lanthanum (La), magnesium (Mg), calcium (Ca), and the like. An anion generating ceramic material is prepared in a slurry state and applied to the funnel 15 of the cathode ray tube. By forming the anion generating material 17 in a slurry state, coating becomes easy, and a constant thickness can be maintained at the time of coating.

FIG. 3 is a schematic exploded perspective view of the inflow delivery part indicated with reference numeral 20 in FIGS. 1 and 2.

Referring to the drawings, the inflow delivery unit 20 may be divided into an upper delivery unit 31 and the lower inlet (32). The bottom of the inlet 32 is installed on the top of the funnel 15 of the cathode ray tube shown in FIG.

The transfer part 31 includes a transfer case 33 and an electromagnet 34 provided at both sides of the transfer case 33. As shown in the drawing, the transfer case 33 has the bottom and the front open, and the back and the left and right sides are closed. Negative ions in the transfer case 33 are introduced from the bottom inlet 36 and are discharged through the front outlet 35. The front discharge opening 35 is exposed to the outside of the front case 11 of the display apparatus 10. Optionally, a plurality of anion passing holes may be formed in the bottom of the transfer case 33.

Electromagnets 39 provided on both outer surfaces of the transfer case 33 generate a Lorentz force that allows negative ions introduced into the transfer case 33 to be discharged through the front discharge port. That is, according to Fleming's left hand law, when a magnetic feed is formed between the electromagnets 39 on both sides, and when negative ions flow in the vertical direction through the bottom suction port 36, the force on the negative ions is applied to the front discharge port 35. Will face. Therefore, negative ions introduced into the transfer case 33 may be transferred to the outside through the front discharge port 35. At this time, the negative ion whose path is changed is divided into two types of movements. Anions that are perpendicular to the magnetic field have a simple circular motion, and anions that are incident at an oblique angle to the magnetic field have a spiral motion. By varying the current applied to the electromagnet 39 it is possible to adjust the size of the magnetic field, thereby adjusting the transmission distance of the negative ions.

The electromagnet 39 provided in the anion transfer unit 31 preferably forms a relatively weak magnetic field so as not to influence the magnetic field on other parts of the display device. Accordingly, the motion radius of the negative ion whose movement path is changed by the Lorentz force becomes very large in inverse proportion to the strength of the magnetic field when other conditions are constant, and negative ions can be transmitted to the user who is spaced apart from the display device 10. have.

The inflow case 37 of the negative ion inflow portion 32 is in a state where the top and bottom surfaces are open, and electromagnets 38 and 39 are provided at both sides. The inflow case 37 is installed close to the surface of the funnel 15 but is not in close contact with the surface of the funnel 15. This is to allow all the ions generated inside the case of the display device to flow through the bottom opening 41 of the inflow case 37. The inflow case 37 preferably has the shape of a tunnel with a predetermined curvature as shown in the figure. In FIG. 2, negative ions generated from the negative ion generating material 17 are introduced from the bottom opening 41 of the inflow case 37 and are sucked into the bottom suction port 36 of the transfer case 33 through the top opening 40. do.

The electromagnets 38 and 39 are provided in a state where a plurality of the electromagnets 38 and 39 are arranged on opposite sides of the case 37. That is, the electromagnets 38 and 39 are installed in mutually aligned state on the opposing surfaces. The electromagnets 38 and 39 provided in the inlet part 32 are for injecting particles with the force of Lorentz generated by the inlet 32 and sending them to the upper transfer case 35. The current applied to the electromagnets 38 and 39 is set differently depending on the position of each electromagnet 38 and 39 relative to the case 37. That is, the Lorentz force is set to allow the negative ions introduced through the bottom opening 41 to move upward in the inflow case 37. At this time, the anion will proceed along the predetermined trajectory.

Whether to apply the inlet 32 in the negative ion generating device is optional. In other words, the negative ion generating device lacking the inlet 32 can also achieve the desired effect to be achieved by the present invention. The inlet 32 serves to transfer negative ions to the transfer case 35, and when the inlet 32 is missing, only the negative ions are introduced into the transfer case 35.

Hereinafter, the operation of the present invention will be described briefly.

When the display device 10 starts to operate, heat is generated in the cathode ray tube due to the thermoelectronic tendency of the electron beam, as is known. At the same time, negative ions are released from the negative ion generating material. These negative ions are present in the space formed between the inside of the case and the funnel 15.

As such, negative ions present in the space are introduced through the bottom opening 41 of the inflow case 37. Negative ions introduced into the inflow case 37 are induced upwards under the influence of the Lorentz force of the electromagnets 38 and 39. The voltage applied to each of the electromagnets 38 and 39 varies depending on the position at which the electromagnet is attached to the inflow case 37, whereby negative ions can travel upward along a predetermined trajectory within the inflow case 37. have. Negative ions are introduced into the transfer case 33 through the top opening 40 of the inflow case 37 and the bottom suction port 36 of the transfer case 33. A magnetic field in the horizontal direction is formed inside the transfer case 33 by the action of the electromagnet 34, and thus, the negative ions are introduced to the front discharge port 35. Negative ions released from the front outlet 35 may reach the user. In order to control the reach distance, the voltage applied to the electromagnet 34 may be adjusted.

In the display device having the negative ion generating device according to the present invention, the negative ions are inversely proportional to the strength of the magnetic field, and the radius of motion increases, and the negative ions can be delivered to the user spaced apart from the display device. According to the experiment, the magnetic induction by the electromagnet of the inlet was not operated, and when the anion was released by Lorentz's force using only the electromagnet provided in the delivery unit, the amount of anion was released at a distance of 50 cm from the display device. When measured by the ion tester (model name: KST-900), the amount of ion emission increased by about 30% compared to the general monitor. In addition, the increase ratio tended to increase as the measurement distance increased.

On the other hand, when the anion is introduced through the inflow case 37 and measured at a distance of 50 cm from the display device, the amount of negative ions increased at a rate of about 40 to 55% compared with the other cases. In addition, as in the above case, the increase ratio increased as the measurement distance increased.

In addition, the display device having an anion generator according to the present invention has the following advantages.

First, the indoor air using the display device can be purified through the negative ions.

Second, the user using the display device may adjust the radiation distance of the negative ions according to the distance away from the display device, so that as many negative ions reach the user as possible.

Third, since ceramics that emit negative ions without using corona or arc discharge are used as negative ion generating materials, it is possible to reduce the generation of harmful substances such as ozone.

Fourth, simple manufacturing is possible because the radiation distance of the negative ions is controlled by controlling the magnetic field by only adjusting the magnitude of the voltage applied to the electromagnet without complicated circuit configuration.

Although the present invention has been described with reference to one embodiment shown in the accompanying drawings, it is merely an example, and those skilled in the art may realize that various modifications and equivalent other embodiments are possible. I can understand. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
