Examples of the fixing member may be a locking ring, a shock absorber installed in the trunk of the vehicle.

Next, the temperature maintaining device 300 serves to maintain the state of the LCD panel 110 in the best state by preventing the internal temperature of the enclosure from leaving a certain temperature region regardless of the external temperature change, and the door ( 200).

At this time, the constant temperature means that when the outside temperature is -50 ℃ ~ +5 ℃, to maintain ± 3 ℃ or more at the minimum +5 ℃, when the outside temperature is +30 ℃ ~ +50 ℃, the maximum + It means to keep ± 5 ℃ or less at 30 ℃.

On the other hand, the temperature maintaining device 300 is provided as an integrated air conditioner consisting of an outdoor unit and an indoor unit, and is installed inside the door 200.

That is, the integrated air conditioner 300 is installed inside the door 200 to blow hot and cold air into the body 100.

At this time, referring to Figure 4 briefly look at the integrated air conditioner as follows.

As shown in FIG. 4, the integrated air conditioner 300, that is, the air conditioner without the outdoor unit, includes a cabinet 301, an electric heater 302 installed inside the cabinet 301, and a compressor 303 for realizing a refrigeration cycle. And a condenser 304, an evaporator 305, an evaporator fan 306, a condenser fan 307, and the like.

At this time, the inlet 301a is formed in the upper part of the cabinet 301, and the outlet 301b is formed in the lower part of the cabinet 301.

At this time, the inlet 301a is provided with a temperature sensor 310 for detecting the temperature of the outside air flowing through the inlet 301a.

At this time, the temperature sensor 310 detects the temperature of the outside air flowing through the inlet 301a and transmits it to the controller (not shown).

At this time, the temperature sensor 310 to operate the electric heater 302 when the temperature of the outside air introduced through the inlet 301a to 5 ℃ in order to maintain the temperature inside the enclosure described above, the electric Preferably, the operation of the heater 302 is set to stop.

In addition, when the temperature of the outside air introduced through the inlet 301a reaches 30 ° C, the refrigeration cycle is operated, and when the temperature reaches 25 ° C, the refrigeration cycle is preferably stopped.

Of course, it does not limit the temperature range of the temperature sensor 310, it can be applied by varying the temperature range for the temperature detection depending on the environment in which the advertising device is installed.

Meanwhile, the refrigeration cycle of the integrated air conditioner 300 will be briefly described as follows.

The high temperature and high pressure refrigerant gas compressed through the compressor 303 passes through the condenser 304, and phase changes into the high temperature and high pressure refrigerant liquid through heat exchange with external air.

At this time, the high temperature heat is discharged to the outside by the condenser fan 307, the refrigerant gas of the high temperature and high pressure is heat-exchanged with the refrigerant liquid of the high temperature and high pressure in the condenser 304.

Thereafter, the refrigerant passes through a filter drier (not shown) and an expansion valve (not shown), lowers the pressure of the refrigerant liquid, changes the state of the refrigerant liquid to a low temperature low pressure, and flows to the evaporator 305.

At this time, in the evaporator 305 to absorb the surrounding heat, the outdoor air passing through the evaporator 305 through the suction port 301a has a low temperature property.

Subsequently, the low temperature low pressure refrigerant liquid is changed into a low temperature low pressure refrigerant gas state and sucked into the compressor 303, thereby generating cold wind while the series of refrigeration cycles is repeated.

On the other hand, the front of the cabinet 301 is provided with a duct 301c for guiding the outside air introduced through the inlet 301a of the cabinet 301 to the outlet 301b of the cabinet 301.

Hereinafter, the coupling and operation of the outdoor advertisement display device having the above configuration will be described.

The glass 120 is installed on the front surface of the body 100, and various devices including the LCD panel 110 are installed behind the glass 120, that is, inside the body 100.

At this time, the gap between the glass 120 and the LCD panel 110 can be minimized.

This is because the integrated air conditioner 300 having excellent cold air generation and delivery power is installed inside the enclosure, so that even if the gap between the glass 120 and the LCD panel 110 is narrow, the cold air can be efficiently delivered.

In the case of the existing outdoor advertisement display device, heat exchanger is used as a means for lowering the temperature inside the housing during the summer, but in this case, since the generation and transfer force of cold air is not maximized, the glass 120 and the LCD panel are By widening the interval between the (110) is the situation that can not help to maintain the temperature for the LCD panel (110).

As such, as the distance between the glass 120 and the LCD panel 110 becomes wider, even though the image quality of the LCD panel 110 itself is clear, the image shown to the outside through the glass 120 is displayed on the LCD panel 110 itself. It is inferior to the image quality of.

On the other hand, the door 200 of the enclosure, as described above, the integrated air conditioner 300 is installed, the evaporator fan 306 of the air conditioner 300 serves to circulate the outside air inside the enclosure while always rotating.

At this time, reference numeral 400 is a blowing fan, guides the wind discharged through the discharge port 301b of the integrated air conditioner 300 serves to blow between the glass 120 and the LCD panel 110.

In the combined outdoor advertisement display device, the temperature inside the enclosure also increases as the summer temperature rises.

At this time, when the temperature of the outside air sucked into the inlet 301a by the evaporator fan 306 is detected at 30 ° C. by the temperature sensor 310, the controller operates the refrigeration cycle.

That is, the integrated air conditioner 300 performing the refrigeration cycle generates a coolant, and the outside air sucked through the inlet 301a is converted into cold while passing through the evaporator 305.

Thereafter, the cold air is discharged through the discharge port 301b through the duct 301c and then blown between the glass 120 and the LCD panel 110 by the blowing fan 400.

Then, if the temperature of the outside air to be sucked is detected by the temperature sensor 310 at 25 ℃, the control unit stops the operation of the refrigeration cycle.

On the other hand, on the contrary, as the winter temperature decreases, the temperature of the outside air sucked by the evaporator fan 306 is also lowered.

At this time, if the temperature of the outside air to be sucked is detected by the temperature sensor 310 at 5 ℃, the control unit operates the electric heater 302.

Thereafter, the sucked outside air is converted into warmth while passing through the electric heater 302.

Thereafter, the warm air is discharged through the discharge port 301b through the duct 301c and then blown between the glass 120 and the LCD panel 110 by the blowing fan 400.

 Subsequently, when the temperature of the suctioned outside air is detected at 15 ° C. by the temperature sensor 310, the controller stops the operation of the electric heater 302.

Accordingly, the LCD panel 110 can maintain a constant temperature even if the temperature outside the enclosure rises or falls.

On the other hand, the housing of the above-mentioned outdoor advertising display device may be provided alone, or may be provided in a multi-vision as shown in FIG.

As described above, the enclosure of the outdoor advertisement display device according to the present invention is a means for maintaining a temperature inside the enclosure, and an integrated air conditioner 300 having an electric heater 302 is provided.

Accordingly, there is a technical feature of high efficiency for cold, warmth generation and transmission,

In addition, as described above, the efficiency of the generation and transmission of cold and hot air is high, and the temperature of the LCD panel 110 can be properly maintained even if the gap between the front glass 120 and the LCD panel 110 is minimized.

That is, as the gap between the glass 120 and the LCD panel 110 is minimized, the image quality of the image viewed through the glass 120 may be maximized.
