Description

  The present invention relates to a waterproof television set installed in a bathroom or the like.

  A conventional waterproof television employs a watertight structure so that water does not enter the casing. A transparent screen display unit is provided on the front surface of the watertight casing, and the built-in liquid crystal display unit faces the screen display unit so that the liquid crystal display unit can be viewed from the outside through the screen display unit.

Among such waterproof television devices, particularly those fixed to the wall of a bathroom are used in an environment where hot water is applied over a long period of time. And a lid body joined from the back side, and the casing body and the lid body are fused over the entire circumference to improve water tightness (for example, see Patent Document 1).
Japanese Patent Laying-Open No. 2004-207801 (FIG. 2)

  In the waterproof television that is used while being fixed to the wall surface of the bathroom as described above, the water vapor in the watertight casing may be condensed on the inner surface of the screen display unit due to a change in room temperature. If condensation occurs on the inner surface of the screen display unit in this way, the screen display unit becomes cloudy and the liquid crystal display unit becomes difficult to see. Therefore, it is necessary to provide a space between the screen display unit and the liquid crystal display unit, and to communicate with this other space in the watertight casing so that the air in the space circulates and can be fogged.

  On the other hand, if dust enters even if it is fine between the screen display unit and the liquid crystal display unit, the dust is conspicuous when watching TV images displayed on the liquid crystal display unit, and the commercial value of the waterproof TV Decreases. Therefore, when assembling a waterproof television, the watertight casing is fused after carefully removing dust such as air blow so that dust does not enter between the liquid crystal display and the screen display.

  However, even if the dust removal operation is carefully performed as described above to remove the dust between the screen display unit and the liquid crystal display unit, the dust may remain in other parts of the watertight casing. Then, after the casing main body and the lid are fused, the remaining dust may enter the space between the screen display unit and the liquid crystal display unit by changing the attitude of the waterproof television apparatus. .

  If the dust enters between the screen display unit and the liquid crystal display unit after the casing body and the lid are fused in this way, the watertight casing cannot be opened, and the waterproof TV must be discarded. A malfunction occurs.

  Therefore, in view of the above problems, the present invention provides a waterproof television apparatus capable of preventing dust from entering the space without impairing the air permeability of the space between the screen display unit and the liquid crystal display unit. The issue is to provide.

  In order to solve the above-described problems, a waterproof television apparatus according to the present invention is a waterproof television in which at least a liquid crystal display unit is stored facing a screen display unit in a watertight casing that cannot be opened and closed and has a transparent screen display unit provided on the front surface. In the television device, a ventilation space allowing air flow in the watertight casing is provided between the liquid crystal display unit and the inner surface of the screen display unit, and the inner surface of the watertight casing is at least an upper portion of the liquid crystal display unit. Further, the present invention is characterized in that a bowl-shaped dustproof portion for preventing dust from entering the space for ventilation is formed.

  It is conceivable that dust remaining in the watertight casing enters the ventilation space due to the drop of gravity. Therefore, by forming a dustproof part at least on the upper part of the liquid crystal display part, even if dust falls from above the ventilation space, it is received by this dustproof part, and entry into the ventilation space is prevented. .

  In particular, the watertight casing is composed of a casing body that forms the front surface side and a lid body that is joined to the casing body from the back surface side, and the casing body and the lid body are melted over the entire circumference. It is suitable for a waterproof television apparatus that employs a configuration that cannot be opened and closed by wearing.

  As is apparent from the above description, the present invention prevents dust from entering the ventilation space by means of the dust-proof part. Therefore, it is possible to prevent the waterproof television apparatus from being discarded due to intrusion of dust.

  Referring to FIG. 1, reference numeral 1 denotes a waterproof television set, which is used by being fixed to a bathroom wall BR in the present embodiment. As shown in FIG. 2, the waterproof television device 1 includes a circuit board 4 including a liquid crystal display unit 41 in a watertight casing including a casing body 2 and a cover plate 3.

  The casing body 2 and the cover plate 3 are fused over the entire circumference and assembled so that hot water does not enter the inside. Therefore, once the casing body 2 and the cover plate 3 are fused, they cannot be separated without destroying the casing body 2 and the cover plate 3.

  A transparent resin screen display unit 21 is bonded to the front surface of the casing body 2. Reference numeral 5 denotes a cosmetic cover that is detachably attached to the front surface of the casing body 2.

  Before the casing body 2 and the cover plate 3 are fused to each other, the surface of the liquid crystal display unit 41 and the inner surface of the screen display unit 21 are particularly carefully blown to perform dust removal work so that no dust remains. . Then, after carefully checking that no dust remains between the liquid crystal display unit 41 and the screen display unit 21, the lid plate 3 and the casing body 2 are fused to each other.

  However, if dust adheres to a place other than the inner surface of the screen display unit 21, the dust may not be completely removed by the dust removal operation. Therefore, as shown in FIG. 3, a dust-proof portion 22 is formed inside the casing body 2 so as to surround the screen display portion 21.

  As shown in FIG. 4, the dustproof part 22 does not prevent the ventilation space 6 formed between the liquid crystal display part 41 and the screen display part 21 from communicating with other parts in the watertight casing. The liquid crystal display unit 41 is formed so as not to contact.

  Even if dust falls from above the liquid crystal display unit 41, it does not get caught in the dust-proof unit 22 and enter the space 6. In the present embodiment, the screen display unit 21 is formed so as to surround from the top, bottom, left and right, but it is necessary to form at least the upper part of the liquid crystal display unit.

  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.
