Standing signboard for flat display}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an advertising stand for a flat panel display, and more particularly to an advertising stand for a flat panel display that can efficiently provide a heating and cooling function for a flat panel display.

In general, a stand type advertising stand is mainly used to display an image of a product more effectively in an exhibition hall or a large shopping mall. The existing stand type advertising stand has been mainly used to insert the advertising paper printed image of the product on the advertising stand.

However, in recent years, as the unit price of the flat panel display becomes cheap due to the development of the flat panel display, an advertising stand using the flat panel is gradually being widely used.

Unlike a conventional advertising stand, an advertising stand using a flat panel display has an advantage of easily replacing an advertising image by simply inputting image data to the advertising stand. However, in an advertising stand using a flat panel display, the heat generated from the flat panel display brings a fatal combination to the blackening phenomenon and the lifespan of the display, thereby failing to provide a desired clear image and information.

In order to solve the above problems, a method has been attempted to cool the heat of the flat panel display by installing a cooling fan in the advertising rack to circulate and cool the air inside the advertising rack. However, in the conventional system, there are the following problems.

1. The conventional method is limited in cooling the display efficiently because the display is simply cooled by an air circulation method using a cooling fan. In other words, in the case of an advertising stand employing a flat panel display, the display is sealed inside the advertising stand. However, when the advertising stand is used outdoors, sunlight is introduced into the advertising stand, and the heat emitted from the display is continuously accumulated in the advertising stand, thereby rapidly increasing the temperature inside the advertising stand. Therefore, such excessive heat accumulation may cause a problem or malfunction in the display.

2. Advertisements are generally used indoors as well as outdoors, making them very vulnerable to the outside environment. Therefore, when the humidity of the air is high due to rain or the like, outside moisture flows into the advertising stand, and thus the introduced water is not easily discharged to the outside of the advertising stand. Prolonged exposure to very humid air. Therefore, this moisture is introduced into the display, there is a problem that a failure or malfunction occurs.

In particular, in rainy weather, dew condensation occurs due to temperature difference between the inside and the outside of the advertising stand, and such condensation is generated on the inner wall of the windshield, thereby causing a problem that obstructs the view of the display.

Accordingly, the present invention has been made to solve the above problems, the technical object of the present invention is to provide an advertising stand for a flat display that can efficiently cool and heat the air inside the advertising stand and the flat panel display.

In FIG. 6, the flat panel display 20 is driven by the controller 40. The controller 40 supplies power to the flat panel display 20 and supplies image data to be output to the display 20. Then, the controller 40 detects the temperature inside the advertising stand through the temperature sensor to operate the air conditioning unit.

When the flat panel display 20 is operated to generate heat from the display 20, and the temperature inside the advertising stand rises above a predetermined temperature by the generated heat, the controller 40 turns the air conditioner 30 into a cooling mode. Will be activated.

When the air conditioner 30 is operated in the cooling mode, the inner fan 31, the outer fan 35, and the compressor 32 operate. When the inner fan 31 is operated, the air pressure of the lower side of the advertisement stand rises, so that the air inside the advertisement stand is circulated along the air passage A as shown in FIG. That is, the cooling air cooled by the evaporator 34 rises upward through the space between the front panel of the flat panel display 20 and the transparent window 11 by the inner fan 31, and then again the flat panel display 20. It descends through the space between the rear of the main body and the main body 10 is introduced to the inner fan 31 again. Then, the heat discharged from the evaporator 34 by this cooling operation is discharged through the discharge port 12 by the external fan 35.

On the other hand, when operating the display 20 in a state in which the outside temperature and the temperature inside the advertising stand lower than a predetermined temperature, such as winter, the controller 40 operates the air conditioning unit 30 in the heating mode.

When the air conditioner 30 is operated in the heating mode, the internal fan 31 and the heater 36 are driven by the controller 40. At this time, the air heated by the heater 36 rises upward through the space between the front panel of the flat panel display 20 and the transparent window 11 as in the cooling mode described above, and then again the rear of the flat panel display 20. It descends through the space between the main body 10 and is circulated through the circulation path flowing back into the inner fan 31.

Therefore, in the above-described apparatus, since the cooling and heating air is continuously circulated through the front and rear of the display 20, the heating and cooling operation for the display 20 is made quickly and effectively, and the advertising stand is circulated by the circulation of the heating and cooling air. Since the internal temperature is kept constant, the temperature is maintained so that there is no abnormality in the operation of the display 20.

7 is a side cross-sectional view of a flat panel display platform according to another embodiment of the present invention, Figures 8 to 10 is an enlarged projection of the lower portion of the flat panel display platform, Figure 8 is a side view, Figure 9 Is a plan view thereof, and FIG. 10 is a rear view thereof.

In the above-described embodiment, the air inside the rack is continuously circulated by the inner fan 31 to shield the outside air from the outside. In this embodiment, the air is introduced into the rack to circulate the inside of the rack. It is configured to be.

In the present embodiment, the inlet 13 for introducing the outside air is formed on the lower surface of the main body 10, the outlet for discharging the internal air to the outside of the main body 10 on the upper side of the air conditioning unit ( 14) is formed.

In addition, a PTFE Membrane filter 50 for filtering the air flowing through the inlet 13 is provided inside the inlet 13, and is rotatable between the PTFE Membrane filter 50 and the inner fan 31. A damper 60 is provided. At this time, the PTFE membrane filter 50 and the inlet 13 are positioned on the same line as the inner fan 31. The PTFE membrane filter 50 is made of a material that allows air to pass but does not pass water and impurities.

In addition, the rotary damper 60 is driven by a motor although not shown in detail. The rotary damper 60 is driven by the controller 40. The rotary damper 60 selectively blocks the internal air from being circulated by blocking the air flowing into the inner fan 31 through the rear side of the flat panel display 20. That is, according to the operation of the rotary damper 60, the air-conditioning operation for the flat panel display 20 is set to the internal circulation or the external circulation.

In addition, since the other structure is substantially the same as the above-mentioned embodiment, the same reference numeral is attached and the detailed description is abbreviate | omitted.

Next, the operation of the embodiment shown in FIGS. 7 to 10 will be described with reference to FIGS. 11 and 12.

When the advertising stand for display is activated, the controller 40 detects the temperature inside the advertising stand through a temperature sensor to operate the air conditioner.

For example, when the display stand is operated in a low temperature state, such as winter, that is, when a temperature below a predetermined level is detected by the temperature sensor, the controller 40 operates the air conditioner 30 in the heating mode.

When the controller 40 operates the display advertising stand in the heating mode, the controller 40 first drives the rotary damper 60 to set the air-conditioning operation for the flat panel display 20 in a bet circulation method.

In the heating mode, the controller 40 drives the inner fan 31 and the heater 36, while the outer fan 35, the compressor 32, the condenser 33 and the evaporator 34 stop driving. .

When the inner fan 31 is driven, the air pressure of the lower side of the advertisement stand rises, so that the air inside the advertisement stand is circulated along the air passage A as shown in FIG. That is, the internal air rises upward through the space between the front panel of the flat panel display 20 and the transparent window 11 by the inner fan 31, and then again the rear side of the flat panel display 20 and the main body 10. It descends through the space between the inner fan 31 is introduced.

In addition, in this case, since the air of the rear side of the display 20 is strongly sucked by the inner fan 31, the air circulated inside is not discharged through the outlet 14. In addition, at this time, since the pressure of the air flowing into the inner fan 31 from the rear side of the display 20 is set to be higher than a predetermined level, external air does not flow through the inlet 13. That is, the inside of the advertising stand is made by the heating operation by the bet circulation method.

On the other hand, when the internal temperature is increased by the heating operation or the internal temperature is increased by the heat emitted from the display 20, and a predetermined temperature or more is detected by the temperature sensor, the controller 40 uses an external air circulation method. The cooling operation is performed.

In the cooling mode, the controller 40 sets the heater 36 in an inactive state, while the internal fan 31, the compressor 32, the condenser 33, the evaporator 34 and the external fan 35 are turned off. It is set to the operation state. In addition, the controller 40 drives the rotary damper 60 to block the internal air circulated through the air passage A from entering the internal fan 31.

When the inner fan 31 is driven, the outside air is introduced through the inlet 13 and the PTFE membrane filter 50, and the outside air thus supplied is cooled through the evaporator 34 and then supplied to the display 20. do.

That is, the cooling air cooled by the evaporator 34 rises upward through the space between the front panel of the flat panel display 20 and the transparent window 11 by the inner fan 31, and then again the flat panel display 20. After descending through the space between the rear of the body and the main body 10 is discharged through the outlet (14).

Therefore, in the above-described apparatus, since the cooling and heating air continuously flows through the front and rear of the display 20, the heating and cooling operation for the display 20 is made quickly and effectively, and the inside of the advertising stand by the flow of the cooling and heating air. Since the temperature of the constant is maintained to maintain the temperature so that there is no abnormality in the operation of the display 20.
