Abstract

PROBLEM TO BE SOLVED: To provide a housing, a display device and a bathroom that can ensure safety even though a conductive cover is used.SOLUTION: A housing houses a display (electric device). A metallic rear cover (cover) 4 comprising the housing is fixed on a metallic chassis 5 included in the display with screws 41 from the rear side. The chassis 5 has bosses 51 into which screws 41 are screwed. An insulating member is disposed between the boss 51 and the rear cover 4 and between the rear cover 4 and the screw 41; thereby the rear cover 4 is insulated from the chassis 5. Noise does not flow via the rear cover 4 from the chassis 5 to the building material of a bathroom in which a display device 1 is attached. The head of the screw 41 does not protrude rearward from the rear surface of the rear cover 4. As the head of the screw 41 does not make contact with the building material, noise does not flow to the building material via the screw 41.

Description

  The present invention relates to a housing for installing an electrical device in a bathroom, a display device, and a bathroom.

  Some thin display devices used as television receivers are fixed to a wall and used. Patent Document 1 discloses a display device to which a wall hanging tool is attached. By the way, as a method of using a display device, it has been proposed to be used in a bathroom. Some display devices used in bathrooms include a housing including a front cover and a rear cover that cover the front and rear of a display unit that displays an image for waterproofing.

  When the display device is used by being embedded in a bathroom wall, the rear cover of the housing forms a part of the wall building material. Since the rear cover requires strength as a building material, the rear cover is often made of metal. In many cases, the rear cover is connected to the chassis in the display device with screws, and the rear cover and the chassis are usually electrically connected.

The hole 42 is closed with a seal 43 after the rear cover 4 is fixed with the screw 41.

  7 is a perspective view of the rear cover 4, and FIG. 8 is a partial cross-sectional view of the rear cover 4 according to the first embodiment. 7 is a perspective view of the rear cover 4 as viewed from the front side, and FIG. 8 is a sectional view taken along line VIII-VIII in FIG. The lower side of FIG. 8 corresponds to the front of the display device 1, and the upper side corresponds to the rear of the display device 1. The rear cover 4 has an attachment portion 44 for attaching the screw 41 from the rear side, and the attachment portion 44 protrudes forward from the plate-like portion 46 of the rear cover 4, that is, inside the housing 10. The attachment portion 44 has a configuration in which a plate-like member is bent so as to protrude forward, and has an elongated shape in the vertical direction. The rear cover 4 has two attachment portions 44, and the two attachment portions 44 are provided in parallel. The two attachment portions 44 are formed with two holes 45 through which the shaft of the screw 41 passes. The attachment portion 44 is formed of a member different from the plate-like portion 46, and is attached to the front surface of the plate-like portion 46.

  FIG. 9 is an enlarged cross-sectional view in which a connecting portion between the chassis 5 and the rear cover 4 according to Embodiment 1 is enlarged. The lower side of FIG. 9 corresponds to the front side of the display device 1, and the upper side corresponds to the rear side of the display device 1. The hole 42 formed in the rear cover 4 is larger in diameter than the head of the screw 41. A boss 51 into which the screw 41 is screwed protrudes rearward from the plate-like chassis main body 52. The screw 41 has a shaft passing through a hole 45 formed in the attachment portion 44 of the rear cover 4 and is screwed into the boss 51. The rear cover 4 is fixed to the chassis 5 by being connected by screws 41. An insulating sleeve 61 is disposed at the rear end of the boss 51. The sleeve 61 is formed of an insulating material in a shape having a cylindrical portion 612 and a flange portion 611 continuous with the front end of the cylindrical portion 612. The cylindrical portion 612 is fitted in the hole 45, and the shaft of the screw 41 passes therethrough. The rear side of the flange portion 611 is in contact with the peripheral portion of the hole 45 of the mounting portion 44, and the front side is in contact with the rear end of the boss 51. Since the insulating sleeve 61 is disposed between the boss 51 and the mounting portion 44, the chassis 5 and the rear cover 4 are not brought into contact and conducting.

  In addition, an insulating washer 62 is fitted to the screw 41. The washer 62 is disposed on the rear side of the mounting portion 44 and is in contact with the rear end of the sleeve 61. The washer 62 is sandwiched between the head of the screw 41 and the rear end of the sleeve 61. Further, an annular insulating sheet 63 is disposed between the washer 62 and the attachment portion 44. The insulating sheet 63 is externally fitted to a portion where the sleeve 61 protrudes rearward from the rear surface of the mounting portion 44, and fills a gap between the washer 62 and the rear surface of the mounting portion 44. The cylindrical portion 612 of the sleeve 61 insulates between the mounting portion 44 and the shaft of the screw 41, and the washer 62 and the insulating sheet 63 insulate between the mounting portion 44 and the head of the screw 41. Since the insulating sleeve 61, the washer 62, and the insulating sheet 63 are disposed, the attachment portion 44 and the screw 41 are insulated from each other. Although the screw 41 is screwed into the boss 51 to conduct between the screw 41 and the chassis 5, the mounting portion 44 and the screw 41 are insulated from each other. And do not conduct. The flange portion 611 of the sleeve 61 corresponds to the first insulating member in the present invention, and the cylindrical portion 612 corresponds to the second insulating member in the present invention. The washer 62 and the insulating sheet 63 correspond to the third insulating member in the present invention. Note that the washer 62 and the insulating sheet 63 may be integrated. Further, the flange portion 611 and the cylindrical portion 612 may be separated. In addition, the display device 1 may include an insulating member in which the sleeve 61, the washer 62, and the insulating sheet 63 are integrated, and the insulating member corresponding to the flange portion 612 separated from the cylindrical portion 612 and the sleeve 61, the washer 62, and the cylindrical member 612 may be provided as an integrated member.

  The screw 41 screwed and fastened into the boss 51 completely enters the hole 42, and the rear end of the screw 41 is located in front of the rear surface of the rear cover 4. The sizes of the screw 41, the mounting portion 44, the boss 51, the sleeve 61, the washer 62, and the insulating sheet 63 are determined so as to have such a positional relationship. For this reason, the head of the screw 41 does not protrude rearward from the rear surface of the rear cover 4, that is, outside the housing 10. Further, as shown in FIG. 8, an insulating seal 43 is attached to the rear cover 4 to close the hole 42 from the rear side.

  As described above in detail, in the display device 1 according to the present embodiment, the metal rear cover 4 is fixed to the chassis 5 with the screws 41, and the chassis 5 and the rear cover 4 are insulated. For this reason, there is no conduction between the chassis 5 and the rear cover 4, and no noise flows from the chassis 5 to the rear cover 4 even when high-voltage noise enters the display device 1 due to lightning or the like. Accordingly, noise does not flow from the rear cover 4 to the bathroom structure and the user is not affected, and the safety of the display device 1 is ensured. Since the safety of the display device 1 is ensured while using the metal rear cover 4, the display device 1 can be used in a bathroom where the strength of the rear cover 4 is required.

  Further, in the display device 1 according to the present embodiment, the head of the screw 41 for fixing the rear cover 4 does not protrude rearward from the rear surface of the rear cover 4. For this reason, the screw 41 does not come into contact with the building material of the bathroom 2, and noise does not flow to the building material through the screw 41 and the user is not affected. Therefore, the display device 1 has high safety. Further, the head of the screw 41 is covered with an insulating seal 43 from the rear side. For this reason, it is prevented more reliably that the bis | screw 41 contacts the building material of the bathroom 2, and the safety | security of the display apparatus 1 becomes more reliable.
