Consequently, solved are the problem that the casing tends to decrease in strength since (1) the casing is constituted by joining the casing body 2 and a lid plate to keep the inner side of the casing airtight from the outside and (2) while the casing recently becomes large in size for a larger screen, a window 12 formed on the casing body 2 that the screen of the liquid crystal display unit 5 faces becomes larger in size relatively to the casing body 12. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a bathroom television fixed to a wall surface of a bathroom, and more particularly to a bathroom having a casing comprising a lid body fixed to the wall surface of a bathroom and a casing body that is watertightly joined to the lid body. 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 in which hot water is always applied, a watertight structure must be provided so that hot water does not enter the casing.

  In addition, electrical components such as a liquid crystal display unit and various printed wiring boards must be built in the casing. Therefore, the casing is composed of a casing main body and a lid, and after the liquid crystal display unit and the electrical component are attached to the casing main body or the lid, the casing main body and the lid are joined to each other in a watertight manner (for example, patents) Reference 1).

In such a bathroom TV, a window portion facing the liquid crystal display unit is formed in the substantially central portion of the lid, and the TV image displayed on the liquid crystal display unit built in the casing interferes with the window portion. Can do.
Japanese Patent Laid-Open No. 9-27993 (FIGS. 4 and 5)

  It is assumed that the size of the liquid crystal display unit illustrated in the above-mentioned patent document is relatively small. However, large-sized liquid crystal display members used in liquid crystal display units have recently been manufactured at low cost. Along with this, the screen size of the bathroom television tends to increase. For example, when the screen of the liquid crystal display member exceeds 10 inches, the width of the casing is 40 cm or more.

  This casing is composed of a casing body provided with a window hole facing the liquid crystal display unit, and a lid joined to the back of the casing body. When the liquid crystal display screen is small, a decrease in strength due to the provision of window holes in the casing body is not a problem. However, when the casing is enlarged, the ratio of the window holes to the area of the casing body increases. Moreover, even if the casing is enlarged, the thickness cannot be increased at the increased ratio.

  Therefore, when the casing is enlarged, the strength of the casing, particularly the casing main body, is greatly reduced. If the thickness of the casing body is increased, the portion may not be easily dented when pressed locally from the front, but an improvement in strength in the torsional direction cannot be expected.

  In addition to the problem of reduced strength of the casing, if a strong impact is applied by, for example, dropping the bathroom television set to the wall surface of the bathroom, a failure may occur in which the connector in the casing is loosened or disconnected. is there. In this case, the cause of the failure is eliminated simply by reinserting the connector.

  However, the casing body and the lid must be joined in a watertight manner. Therefore, the casing body and the lid are bonded to each other or welded to each other. Therefore, once the casing body and the lid are joined, it becomes virtually impossible to repair or maintain the casing without destroying the casing.

  Therefore, in view of the above problems, the present invention provides a bathroom television that does not reduce the strength of the casing and does not loosen or come off the connector inside the casing even when the screen size of the liquid crystal display unit is increased. It is an issue to provide.

  In order to solve the above problems, a bathroom television according to the present invention includes a casing made of a resin lid fixed to a bathroom wall and a resin casing body watertightly bonded to the lid. A bathroom television having a window portion facing the liquid crystal display unit at a substantially central portion of the casing body, and is attached to the inside of the casing body at a plurality of locations set around the window portion, and an outer peripheral portion of the casing body. A reinforcing plate that abuts on the inner wall portion formed in the vicinity from the inside is provided.

  Since the reinforcing plate is made of sheet metal, it has higher rigidity than the resin casing body. By attaching the reinforcing plate at a plurality of locations around the window portion, the strength around the window portion is improved. Therefore, even if the casing body is pushed from the front, it will not be recessed. Moreover, even if an external force acts on the casing body from the lateral direction by making the reinforcing plate abut against the inner wall portion formed near the outer periphery of the casing body from the inside, the reinforcing plate receives the external force from the lateral direction. This prevents deformation such as twisting of the casing.

  The liquid crystal display unit may include a backlight on the back, and the reinforcing plate may be made of metal and function as a heat radiating plate for heat generated by the backlight in contact with the back of the liquid crystal display unit.

  Further, the reinforcing plate has a window portion facing the detachable connector, and a casing body is formed by forming a holding portion on the peripheral portion of the window portion to hold the connector and prevent the connector from falling off. It is possible to prevent a problem that the connector is loosened or pulled out after the cover and the lid are joined to each other.

  The reinforcing plate may function as a bracket for holding the printed wiring board.

  As is clear from the above description, the present invention is provided with the reinforcing plate that reinforces the periphery of the window portion and the outer peripheral edge portion of the casing body. The strength of the casing body can be increased without increasing the wall thickness.

  The heat source having the largest heat generation amount in the casing is the backlight of the liquid crystal display unit. However, if the reinforcing plate is made of metal, heat generation from the backlight can be promoted.

  In addition, since the casing is required to be waterproof, it is possible to prevent the connector from loosening or coming off in the casing with the pressing portion in a state where the casing body and the lid are joined to each other. Failure due to loosening can be prevented.

  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 body 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.

  Referring to FIG. 3, before joining casing body 2 and lid body 3 to each other, liquid crystal display unit 5 and various printed wiring boards 61 and 62 must be attached to 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, and the screen for displaying the television screen is mounted so as to face the window portion 12, 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. Therefore, the reinforcing plate 4 also functions as a heat radiating plate for the liquid crystal display unit 5.

  By the way, mounting seats 21 for screwing are erected at four positions 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 portion 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.

  Further, when the reinforcing plate 4 is fixed to the casing body 2, the vertical piece 41 provided on the reinforcing plate 4 comes into contact with the inner peripheral wall 22 of the casing body 2 as described in detail in FIG. Since the vertical piece 41 is configured to contact the inner peripheral wall 22 in this way, when the reinforcing plate 4 is attached to the casing body 2, the inner peripheral wall 22 serves as a positioning guide and the reinforcing plate 4 with respect to the casing main body 2. Positioning can be performed. Further, in a state where the reinforcing plate 4 is fixed to the casing body 2, for example, even if the inner peripheral wall 22 tries to deform inward, the vertical piece 41 supports the inner peripheral wall 22 and prevents the inner peripheral wall 22 from deforming inward. . As described above, when the deformation to the inside of the inner peripheral wall 22 is prevented, when the external force is applied to the casing body 2 from the lateral direction, the reinforcing plate 4 prevents the deformation of the casing, and the deformation in the twisting direction is also prevented. This is prevented by the reinforcing plate 4.

  Returning to FIG. 3, the reinforcing plate 4 is formed with a seat 43 for attaching the printed wiring boards 61 and 62. 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.

  Furthermore, the reinforcing plate 4 is formed with an opening 44 through which a lead wire connected to a connector 71 disposed below the reinforcing plate 4 is drawn. As shown in FIG. 5, a pair of pressing claws 42 is formed in the opening 44. The connector 71 is attached to a printed wiring board 51 positioned below the reinforcing plate 4, and the lead wire 7 connects the printed wiring board 51 and the printed wiring board 61 attached to the upper portion of the reinforcing plate 4. is there.

  When the reinforcing plate 4 is fixed to the casing body 2, the pressing claw 42 presses the connector 71 from above. In this state, there is no problem that the connector 71 is loosened or detached even when external vibration or impact is applied.

  By the way, since the reinforcing plate 4 is interposed between the printed wiring boards 61 and 62 and the liquid crystal display unit 5, the heat generated from the liquid crystal display unit 5 does not directly affect the printed wiring boards 61 and 62. In the above-described embodiment, the reinforcing plate 4 is made of sheet metal so as to efficiently dissipate heat generated by the liquid crystal display unit 5. However, when the necessity for heat dissipation of the liquid crystal display unit 5 does not matter so much. The reinforcing plate 4 may be formed of a material other than metal, such as plastic.

  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.
