Description

  The present invention relates to a frame for an image display device used for an image display device arranged in a recess provided in a wall.

  In recent years, image display devices that display images such as television images have been made thinner. With the thinning of image display devices, thin image display devices including so-called flat display panels such as plasma display panels or liquid crystal panels are becoming the mainstream in place of conventional image display devices including CRT (Cathode Ray Tube). It has become.

  FIG. 8 is a perspective view of a plasma display device 100 as an example of such a flat image display device when observed from the image display surface side. In the plasma display device 100, a plasma display panel (hereinafter referred to as “PDP”) 2 for displaying an image and a circuit board for driving the PDP 2 are covered with a front cover 3 and a back cover 4.

  In the following description, the vertical direction refers to the vertical direction (that is, the vertical direction) when the plasma display device is disposed in a normal use state. Further, the left-right direction indicates a direction orthogonal to this (that is, a horizontal direction).

  FIG. 9 is a schematic cross-sectional view showing an internal configuration of a conventional plasma display apparatus 100. As shown in FIG. 9, inside the front cover 3 and the back cover 4 of the plasma display device 100, a PDP 2 that displays an image, a chassis 5 that supports this on a front surface 5 a via a resin sheet 7, and a chassis 5 And a plurality of circuit boards 6 for driving the PDP 2 attached to the rear surface 5b of the apparatus. As shown in FIG. 9, an accommodation space 11 for accommodating the circuit board 6 is formed between the back surface 5 b of the chassis 5 and the back cover 4.

  Further, an intake port 8 is provided at the lower part of the back cover 4, and an exhaust port 9 is provided at the upper part. Further, a fan 10 is provided inside the back cover 4 at a position corresponding to the exhaust port 9. When the fan 10 is operated, an air flow as indicated by arrows A1 and A2 in FIG. 9 is generated between the storage space 11 inside the back cover 4 and the outside of the back cover 4. In other words, low-temperature air is drawn from the intake port 8, the chassis 5 and the circuit board 6 in the back cover 4 are cooled by forced convection, and high-temperature air is discharged from the exhaust port 9.

  Recently, image display devices have been further reduced in thickness (for example, about 25 mm). The depth of the storage space 11 surrounded by the chassis 5 and the back cover 4 is also very small. In other words, the distance between the intake surface of the fan 10 facing the chassis 5 and the chassis 5 is also reduced. Thereby, the flow path resistance in the storage space 11 increases, and the problem that the air volume of the fan 10 decreases arises.

  For example, Patent Document 1 proposes an image display device that solves the above problem by dividing the storage space 11 inside the back cover 4 into a plurality of vertical regions by a partition wall. According to this configuration, it is possible to reduce the flow resistance of the air flow path from the intake port to the exhaust port in each of the divided areas, thereby improving the cooling efficiency.

  In recent years, the number of cases in which an image display device is disposed in a depression provided on a wall is increasing even at home. In the case where the image display device is arranged in a recess provided in the wall, there arises a problem that high-temperature air discharged from the exhaust port of the image display device stays in the recess. As shown in FIG. 10, the gap between the back cover 4 and the inner surface 103 a of the recess 103 is small (for example, 60 mm or less), and there are peripheral surfaces 103 b on the top, bottom, left, and right. This is because high-temperature air hardly passes through the space between the image display device 100 and the inner surface 103a and the peripheral surface 103b of the recess and is not easily discharged out of the recess 103. If the high-temperature air discharged from the image display device 100 stays in the recess 103, the high-temperature air discharged from the image display device 100 is sucked again from the intake port 8 of the image display device 100, and the image display device 100 is sufficiently charged. There is a risk that it will be impossible to exhaust heat.

  In order to discharge the high-temperature air staying in the dent outside the dent, for example, it is conceivable to increase the number of fans inside the casing of the image display device or to replace the fans inside the casing with high performance fans. . Thereby, even when only a narrow flow path is formed around the image display device, the high-temperature air discharged from the image display device can be efficiently discharged out of the recess. However, except for the case where the image display device is arranged in the recess, the design becomes excessive and the manufacturing cost becomes high.

  In view of the above-described problems, an object of the present invention is to enable high-temperature air discharged from an image display device to be discharged out of a recess when placed in a recess provided in a wall.

  In order to solve the above-described problem, the present invention provides a frame installed around an image display device arranged in a posture in which a display surface faces forward, and the space around the image display device is defined in the image display device. A main body provided with an exhaust port that communicates the first space and the second space, and a first space on the front side of the image display device and a second space on the rear side of the image display device, and the exhaust port. And a fan for flowing air from the second space to the first space.

  According to the present invention, when the image display device is arranged in a recess provided on the wall, the fan of the image display device frame forms an air flow, so that a stronger air current is generated outside the image display device. Can be generated. That is, the high-temperature air generated in the image display device and discharged from the image display device can be discharged out of the recess by the fan included in the image display device frame. In this way, the frame for the image display device can suppress the retention of the hot air in the recess. Further, since the image display device frame can be removed when the image display device is not disposed in the recess, it is possible to avoid excessive design of the image display device itself.
