Description

  The present invention relates to a television for a bathroom fixed to a wall surface of a bathroom, and more particularly to a bathroom having a casing comprising a lid fixed to the wall of the bathroom and a casing main body that is watertightly joined to the lid. Regarding TV.

  There is a demand for watching TV images while taking a bath, and many TVs for bathrooms have been proposed in recent years. Since such a bathroom TV is exposed to an environment where hot and cold water is always applied, a watertight structure must be provided so that hot water does not enter the casing.

  On the other hand, a large-sized liquid crystal display member used for a liquid crystal display unit housed in a casing has recently been manufactured at a low cost. Accordingly, the amount of heat generated in the backlight portion of the liquid crystal display unit is also increasing.

  In order to diffuse the heat generated in such a backlight part, a metal heat radiating plate is in contact with the back part of the liquid crystal display unit so that the heat generated by the backlight part is radiated into the casing. (For example, refer to Patent Document 1).

Japanese Patent Laying-Open No. 2005-318114 (Claim 2)

  In the above-mentioned conventional bathroom night TV, a large amount of heat is generated from the backlight part. Even if the heat is radiated by the heat radiating plate, the heat is only transmitted to the air in the casing, and the casing is watertight. Since it is a structure, since the internal air is not ventilated, the malfunction that the temperature in a casing becomes high temperature arises.

  Then, this invention makes it a subject to provide the television for bathrooms which can suppress the temperature rise in a casing, without making the water-tightness of a casing suitable in view of said problem.

  In order to solve the above problems, a bathroom television according to the present invention is a bathroom television in which a liquid crystal display unit having a backlight is housed in a watertight casing fixed to a wall surface. An opening is provided and the opening is watertightly closed with a metal plate. When the casing is fixed to the wall surface, a heat transfer material is interposed between the wall surface and the metal plate, and the heat in the casing is transferred from the metal plate. It is configured to escape to the wall surface through the heat transfer material.

  The part of the wall surface to which the casing is attached has a temperature lower than the temperature inside the casing when the backlight part is operating. Therefore, the temperature gradient is high in the casing and the wall surface is low, and the heat in the casing is transferred to the wall surface through the metal plate and the heat transfer material and escapes.

Incidentally, the heat transfer material has been made to elastically deform, the metal plate is bonded from the outside peripheral edge of the opening, a metal plate restoring force of the heat transfer material in a state of mounting the casing to the wall this if configured to act in a direction to press the periphery of the opening, hardly impaired watertightness in sticking portion of the metal plate.

  As is clear from the above description, the present invention allows the heat in the casing to escape to the wall surface to which the casing is attached, so that the temperature rise in the casing can be suppressed.

  Referring to FIG. 1, BR is a bathroom, and bathroom television 1 is attached to wall surface W of bathroom BR. As shown in FIG. 2, the bathroom television 1 includes a casing including a lid 3 fixed to the wall surface W and a casing body 2 joined to the lid 3 so as to be watertight. Yes. Reference numeral 11 denotes a cosmetic cover that is detachably attached to the front, that is, from the casing body 2 side in a state where the casing body 2 and the lid 3 are joined to each other.

  The bathroom television 1 is formed with a window portion 12 showing a large area of the front surface on the front surface of the casing body 2 so that the screen of the liquid crystal display unit housed in the casing faces the window portion 12. Is set.

  Before the casing body 2 and the lid 3 are joined to each other, the liquid crystal display unit 5 and various printed wiring boards 61 and 62 must be attached to the casing body 2. In the present invention, the reinforcing plate 4 is attached to the casing body 2 in accordance with the attachment.

  Both the casing body 2 and the lid body 3 are injection-molded with a thermoplastic resin. On the other hand, the reinforcing plate 4 is made of metal, and is formed by sheet metal processing a metal thin plate. Although the liquid crystal display unit 5 described above is unitized although not shown in the figure, the screen for displaying the television screen is attached so as to face the window portion 12, so that the backlight of the liquid crystal display unit 5 is located on the rear side. . The reinforcing plate 4 is positioned behind the liquid crystal display unit 5, and the rear surface of the liquid crystal display unit 5 comes into contact with the reinforcing plate 4.

  Then, heat generated from the backlight in the liquid crystal display unit 5 is transmitted to the reinforcing plate 4. Since the reinforcing plate 4 is made of metal as described above, the transmitted heat is quickly conducted to the entire area of the reinforcing plate 4 and then radiated.

  By the way, mounting seats 21 for screwing are erected at four locations so as to surround the window 12 on the inner surface of the casing body 2. Since the four mounting seats 21 are integrally reinforced through the reinforcing plate 4, the strength around the window 12 is increased. Therefore, even if the vicinity of the window 12 is pushed from the front after the lid 3 is joined to the casing body 2, the reinforcing plate 4 is fixed to the mounting seat portion 21, so that the casing body 2 is not changed.

  A seat 43 for attaching the printed wiring boards 61 and 62 is formed on the reinforcing plate 4. Therefore, after fixing the reinforcing plate 4 to the casing body 2, the printed wiring boards 61 and 62 function as brackets for mounting the printed wiring boards 61 and 62.

  Further, the reinforcing plate 4 has an opening 44 through which a lead wire connected to a connector disposed below the reinforcing plate 4 is drawn. As shown in FIG. 5, a pair of pressing claws are formed in the opening 44. The connector is attached to a printed wiring board 51 positioned below the reinforcing plate 4, and the lead wire connects the printed wiring board 51 and the printed wiring board 61 attached to the upper portion of the reinforcing plate 4.

  When the reinforcing plate 4 is fixed to the casing body 2, the pressing claw holds the connector from above. In this state, there is no problem that the connector is loosened or disconnected even when external vibration or impact is applied.

  With reference to FIG. 4, the opening 7 was formed in the back surface of the casing main body 2, the metal plate 8 was stuck from the outer side with respect to the peripheral edge 71 of the opening 7, and the opening 7 was obstruct | occluded watertight. Then, the casing body 2 was fixed to the wall surface W so that the heat transfer material 9 made of resin having heat conductivity was sandwiched between the wall surface W and the metal plate 8. In addition, since the said reinforcement board 4 becomes high temperature, the same heat-transfer material 91 was interposed also between the reinforcement board 4 and the metal plate 8. FIG.

  With this configuration, heat flows from the reinforcing plate 4 that has become high temperature to the metal plate 8 via the heat transfer material 91, and further, the heat escapes to the wall surface W via the heat transfer material 9, and the casing body The temperature rise inside 2 is alleviated.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention.
