Description

  The present invention relates to a bathroom electronic device that includes a watertight casing and is installed in a bathroom, such as a bathroom television or a bathroom remote controller.

  Since this type of conventional bathroom electronic device is used in a bathroom, a watertight casing is employed so that water and water vapor do not enter the casing. However, an image display unit, other electronic boards, and other electronic members are built in the casing, and when energized, heat is generated inside the casing and the air inside expands. Conversely, when energization stops, the air inside the casing is cooled and contracts. If the internal air gradually leaks during expansion, the internal pressure becomes non-pressure during cooling, and moisture may be sucked into the casing. Moreover, in the case of providing a speaker such as a bathroom television, the diaphragm is bent by the pressure in the casing, so that the sound quality may be deteriorated or the speaker may be damaged.

  In addition, if moisture is sealed when the casing is sealed, the interior of the transparent portion provided for viewing the image display unit in the bathroom television is cloudy, resulting in a problem that the viewability of the image display unit is impaired.

Therefore, the casing is actively opened to a position where moisture does not reach in the bathroom to allow ventilation, so that the pressure in the casing does not change and the water vapor enclosed inside is discharged to the outside. Thus, a ventilation hole is formed in the casing itself (see, for example, Patent Document 1).
JP 2004-208046 A (FIG. 3)

  If only the ventilation hole is provided in the casing, there is a risk that a small insect may enter the casing through a hole formed in the wall surface for passing cables. Further, when dust enters from the air holes, there is a problem that dust enters between the image display portion and the transparent portion, making it difficult to see. Therefore, a small hole is formed on the back surface of the casing as a ventilation hole, and the ventilation hole is covered with a ventilation seal from the inside of the casing.

  This ventilation seal is a seal in which a large number of fine holes are formed, which allows gas such as air and water vapor to pass through but blocks solid matter. In order to attach this ventilation seal, it is necessary to secure a margin for adhering the ventilation seal around the ventilation hole. However, when the casing is made compact, there is a case where the margin for the ventilation seal cannot be secured. In addition, if the ventilation holes are formed on the back of the casing, the inside of the bathroom and the position of the ventilation holes are very close, so if the waterproof construction between the wall surface and the casing is insufficient, water will penetrate to the position of the ventilation holes. There is a fear.

  Therefore, in view of the above problems, the present invention provides a bathroom electronic device that can reliably prevent moisture from entering and secure ventilation between the inside and outside of the casing regardless of the design of the casing. This is the issue.

In order to solve the above problems, the bathroom electronic device according to the present invention comprises an electronic board and other electronic members in a watertight sealed casing, and in the bathroom electronic device installed in the bathroom, on the back surface of the casing, Attach a harness in which cables connected to the circuit board and other electronic components in the casing are integrated, and incorporate a ventilation tube with the cables in this harness, open one end of the ventilation tube in the casing, and so on. The end of the vent tube is open to the atmosphere outside the bathroom, and a flange part is provided at the one end of the vent tube to which a vent seal can be attached. The solid material is prevented from entering the casing .

  Ventilation between the inside and outside of the casing is performed through a ventilation tube. The position of the other end of the ventilation tube can be freely set. For example, the other end of the ventilation tube can be positioned at a position away from the bathroom and not exposed to water.

  In addition, although it is desirable to stick a ventilation seal to one end of the ventilation tube, it is difficult to secure an adhesive margin for the ventilation tube as it is. Therefore, in such a case, a flange portion to which a ventilation seal can be attached is provided at the one end of the ventilation tube, the ventilation seal is attached to the flange portion, and the solid matter passes through the ventilation tube into the casing. Can be prevented from entering.

  By the way, if the flange part is molded integrally with the casing, the number of parts is not increased.

  As is clear from the above description, the present invention performs ventilation between the inside and outside of the casing through the ventilation tube, so that the position of the other end that is an opening to the outside of the ventilation tube can be freely set. And since the ventilation tube was incorporated in the harness, the ventilation tube can be installed without being influenced by the design of the casing.

  Referring to FIG. 1, reference numeral 1 denotes a bathroom television as an example of a bathroom electronic device according to the present invention, which is fixed to a wall W of a bathroom BR. As shown in FIG. 2, the bathroom television 1 includes a casing in which a front cover 2 and a rear cover 3 are joined in a watertight manner. A detachable decorative cover 11 is attached from the front. The decorative cover 11 is not essential, and the decorative cover 11 may be eliminated depending on the design of the front cover 2.

  The front cover 2 is provided with a transparent window portion 21 for viewing a television image displayed on the internal image display portion from the front. Further, the rear cover 3 is fixed so as to be in close contact with the wall W of the bathroom BR.

  Referring to FIG. 3, in a casing formed by front cover 2 and rear cover 3, an image display unit 22 composed of a liquid crystal display unit, and a communication for communicating with a driver circuit of image display unit 22 and the outside. An electronic substrate 23 on which a circuit and other electronic circuits are formed is incorporated. The electronic board 23 and an external tuner unit (not shown) are connected via a plurality of cables. These cables are collected as one harness and attached to the insertion port 31 formed in the rear cover 3.

  Referring to FIG. 4, when attaching bathroom television 1 to wall portion W, opening WH through which harness 4 is passed through wall portion W is formed in advance. The front cover 2 and the rear cover 3 are joined to each other with the harness 4 attached to the rear cover 3. Since this harness 4 is formed with a plug portion 41 that closes the insertion port 31 in a liquid-tight manner, water or the like does not enter the casing from the insertion port 31 when the harness 4 is attached.

  As described above, various cables 42 are collected in the harness 4. In the present invention, the ventilation tube 5 is further incorporated in the harness 4 together with the cable 42. The other end 51 of the ventilation tube 5 is pulled out to a position sufficiently away from the bathroom BR and fixed by a fixing band (not shown) or the like. On the other hand, one end 52 of the ventilation tube 5 is located in the casing and opens into a space in the casing.

  In the present embodiment, the flange member 6 is attached to one end 52 of the ventilation tube 5. As shown in FIG. 5, the flange member 6 is configured such that the leg portion 61 is inserted into one end 52, and the internal passage of the ventilation tube 5 communicates with the opening 62 of the flange member 6. A flange margin 63 is formed around the opening 62 in the flange member 6. A ventilation seal 7 is attached to the margin margin 63 and the opening 62 is closed with the ventilation seal 7.

  As described above, the vent seal 7 allows gas to pass through but does not allow solids to pass through. Even if a small insect enters the vent tube 5 from the other end 51, the vent seal 7 allows the small insect to enter the casing. Intrusion is prevented.

  Incidentally, as shown in FIG. 6, the flange portion 32 is formed integrally with the rear case 3 without using the flange member 6, and one end 52 of the ventilation tube 5 is connected to the flange portion 32, and the ventilation seal 7 is attached. You may make it stick.

  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. For example, in the above embodiment, the entire rear surface of the bathroom TV 1 is fixed to the wall portion W of the bathroom BR and the surroundings of the bathroom TV 1 are caulked. The angle of the television 1 may be adjusted.
