する屋外用表示装置の排気方式に関する。Description: TECHNICAL FIELD The present invention relates to a method of exhausting hot air inside a housing mounted with a display device, and particularly for outdoor use to display securities information and the like on an outdoor wall or pillar. The present invention relates to an exhaust system of a display device.

を前記空気流通路に送り込む方式となっていた。Conventionally, a display device of this type uses a partition plate around the display device mounting portion to form an air duct between the outer wall of the housing and the display device to form an intake / exhaust air flow passage to prevent hot air from flowing through the display device. It was a system of sending it to the air flow passage.

曇りが発生する恐れがある。As described above, in the conventional outdoor display device, as shown in FIG. 9, the hot air generated inside the display device is exhausted to the display device mounting portion and then sent to the air flow passage by the exhaust fan. The hot air of the display part stays in the upper corners of the display device, etc., and the cooling effect of the device is reduced. Since the flow of air is not constant, there is a drawback that the air flow must be balanced by adjusting the air flow rate of the exhaust fan inside the display device and the air flow direction in order to prevent the occurrence of fogging on the glass surface. Further, as shown in FIG. 10, it is difficult to secure the air flow between the front surface of the display device and the glass surface of the housing by the method of directly sending the air into the air duct by using the exhaust fan inside the display device. May fog on the glass surface of.

Referring to FIG. 6 and FIG. 6, partition plates 11, 12, and 13 are provided on the upper surface and both side surfaces of the main body 1-1, and the abutting portions of the partition plates are connected to each other so that air can flow therethrough. At least one exhaust fan 3-1 or 3-2 or 3-3 is provided in part. A display device mounting plate 17 and a mounting hole 18 are attached to the partition plates 12 and 13, and a shielding plate 19 which also serves as a display device mounting base is attached to the lower part to form a display device mounting space. Further, the partition plate 11 is provided with a partition plate 20 for dividing the front side and the back side of the display device into two when the display device is mounted, and for blocking the display device. Further, an exhaust fan is formed above the front side space a. is doing. If necessary, air flow guide plates 6 and 7 are provided on the exhaust side of the exhaust fans 3-2 and 3-3 to improve exhaust efficiency. A transparent glass having a drip-proof structure is arranged in front of the cover 1-2 connected by the hinges 8, and partition plates 12 'and 13' are fixed to both sides of the cover to close the cover 1-2.

By dividing and shielding the front side and the rear side and sending the hot air generated in each space into the air duct with each exhaust fan, the air volume in each space can be controlled freely, so a ventilation example is set. In summer, the air volume in the display device is increased to improve the cooling effect of the device. Further, in winter, it becomes easy to increase the amount of airflow between the glass surface and the display device to prevent the occurrence of fogging on the glass surface. In addition, even if the air volume is not controlled, the exhaust fan is provided for each, so that there is no stagnation of hot air in the display unit mounting space and a reliable ventilation effect is obtained, so the heat of the sunlight is displayed by the air duct system.
