Description

  The present invention relates to a cabinet and a display device, and more particularly, to a cabinet provided with an exhaust opening and a display device including such a cabinet.

  Generally, a television cabinet is provided with an opening for heat dissipation (a heat radiation port). And in the thin television which is a television generally used in recent years, a heat radiation opening is often provided in the upper part of the cabinet from the viewpoint of spontaneous emission by convection. In such a structure, if water is spilled from the upper part, water may easily enter the cabinet and the television may break down. Naturally, if there is no heat radiating opening at the top, the temperature inside the cabinet will rise, causing a failure.

  Therefore, various techniques have been proposed and adopted so that water does not enter the cabinet. For example, there is a technique for completely protecting the interior with a metal cabinet and waterproofing in a television set that is assumed to be used outdoors (see Patent Document 1). And in this technique, heat dissipation is also realized by attaching a fin structure to the metal cabinet at the same time. In addition, there is a technique for opening and closing a slit provided in a ceiling portion in accordance with turning on and off of a power supply (see Patent Document 2).

  In addition, as shown in the side view of FIG. 1A, the exhaust part 130 provided on the top surface of the cabinet 120 of the television 100 is stepped, and an opening 101 is provided between the steps. There is also a technology that makes it difficult for water 105 to enter the interior of the inclined surface 102, and is adopted in the product of the present applicant. Furthermore, as shown in FIG. 1C, there is a technique in which ribs (walls) 103 are slightly extended from the inclined surface 102 into the opening 101 to make it difficult for water 105 to enter.

  By the way, with the technique disclosed in Patent Document 1, the mass production type television is too costly and heavy, and this technique cannot be employed. Further, in the technique disclosed in Patent Document 2, when the power is on, the slit is open, so there is a risk that water may enter, which is insufficient as a countermeasure and another technique is required. It was. There was also a strong demand for structurally simpler technology. Further, in the technique shown in FIG. 1A, a simple structure can effectively cope with waterproofing from above, but as shown in FIG. There is also a risk of entering the pool. Also in the structure of FIG. 1C, another technique has been demanded because water 105 accumulates in the inclined portion and enters the television when it passes over the upper portion of the inclined surface.

  An object of the present invention is to provide a technique for solving the above-described problems.

The device according to the present invention is a cabinet of a display device having a heat radiation opening formed in a plurality of stages in the vertical direction, and the shape constituting the opening has a predetermined length in the front-rear direction so that the rear becomes lower. An inclined surface formed and a groove formed extending in the lateral direction on the inclined surface are provided.
In addition, the inclined surface may be formed in a stepped shape that decreases in the rearward direction on the upper surface portion of the display device, and the opening may be formed between the plurality of inclined surfaces.
The groove may have an end lower than the central portion.
The groove may have a convex shape inside the cabinet, and the convex portion may function to promote heat release inside the display device.

  Next, embodiments for carrying out the present invention will be specifically described with reference to the drawings. The outline of the feature of the present embodiment is that a drainage groove is provided in an inclined portion in an exhaust port provided in a television cabinet so that water does not enter the inside from the inclined portion.

  FIG. 2 is a diagram schematically illustrating the television 10 according to the present embodiment, focusing mainly on the exhaust unit 30 provided on the upper surface of the cabinet 20. 2A is a rear view of the television 10, and FIG. 2B is a diagram showing a side end (left end in the figure) of FIG. 2A. The exhaust part 30 has a structure similar to that of the exhaust part 130 shown in the prior art of FIG. 1 except that the groove 13 is mainly provided on the inclined surface 12. FIG. 3 is a diagram focusing on the movement of the water 50 when water is applied from above the television 10 having a structure corresponding to FIG. Furthermore, the shape of the inclined surface 12 is shown in FIG. In the drawings in the present embodiment, the reference numerals are omitted as appropriate when the drawings are complicated.

  Specifically, as shown mainly in FIG. 2 (b), the exhaust part 30 is provided between the two inclined surfaces 12 and the inclined surface 12 formed in three steps in a stepped manner so as to descend backward. And an opening 11 formed therein. In FIG. 2A, the opening 11 is shown in black. Further, the inclined surface 12 extends in the left-right direction as shown in FIGS. 2A and 3B, and is formed so that the rear side is lowered as shown in FIG. 2B. . With this structure, the water 50 spilled from the top flows down to the rear side. Further, a groove 13 extending in the left-right direction is formed in the approximate center of the inclined surface 12 in the front-rear direction so that the water 50 does not easily enter the opening 11. Here, the groove 13 has a V-shaped cross section, but is not limited to this shape, and may have a U-shaped cross section, for example. Further, the depth of the second-stage groove 13 and the third-stage groove 13 may be different, or may be different from the shape and depth.

  Further, as shown in FIGS. 4A to 4C, the depth of the groove 13 is the shallowest at the left and right center position (AA cross section), and becomes deeper toward the side, and is the left and right ends. It is deepest at the groove side end 13b. That is, as can be seen from a comparison between FIGS. 4A and 4B, the groove lower end portion 13a of the groove 13 is formed at the highest position in the center and is at the lowest position at the groove side end portion 13b. Thus, the water 50 that has entered the groove 13 is discharged from the groove-side end portion 13b.

  As shown in FIGS. 3 and 4, the water 50 spilled on the upper part of the cabinet 20 of the television 10 travels down the inclined surface 12 and falls down to go down the stairs. And the front side edge part 12a of the inclined surface 12 is in a position where it enters the front side rather than the rear side edge part 12b of the upper inclined surface 12 so that the water 50 that has fallen from above does not enter the opening 11. It has become. That is, a part of the inclined surface 12 overlaps when viewed from above. Further, the second-stage inclined surface 12 and the third-stage inclined surface 12 are similarly arranged.

  All or part of the water 50 that has fallen from the first-stage inclined surface 12 to the second-stage inclined surface 12 enters the groove 13, and the water 50 that has entered the groove 13 is directed toward the groove-side end portion 13b. And is discharged from the flow groove side end portion 13b. The water 50 that has not been taken into the groove 13 of the second-stage inclined surface 12 is transmitted to the third-stage inclined surface 12, and all or part of the water 50 is taken into the groove 13, transmitted through the groove 13, and the groove side. It is discharged from the end 13b.

  Next, the exhaust heat rectification function of the groove 13 provided on the inclined surface 12 will be described. In the case of the shape shown in FIG. 1, the surface on the inside of the cabinet 120 of the inclined surface 102 acts to move air (heat) forward, and the efficiency of exhaust heat from the opening 101 decreases. On the other hand, in this embodiment, as shown in FIGS. 5A and 5B, the groove 13 has a protruding shape inside the cabinet 20. As a result, the groove 13 can change the moving direction of air (heat), and the exhaust heat efficiency of the opening 11 can be improved.

By adopting such a structure, when the water is transmitted from the center in the groove 213 and the water spilled from the top of the groove 213 is merged and increases from the groove 213 toward the side end. Even so, it can be easily spilled not on the inside (front side) but on the outside (rear side). Note that the second-stage inclined surface 212 may have the shape shown in FIG. 2 or the like, and the third-stage inclined surface 212 may have the shape of this modification.

  Moreover, the inclined surface 312 which concerns on the modification of Fig.7 (a)-(c) is shown. The inclined surface 312 in FIG. 7A has a shape such that the surface of the inclined surface 312 becomes lower toward the side end surface from the center in accordance with the horizontal inclination of the groove 313 (groove lower end 313a). .
