２ｂ、第３図のように逆り字形２ｃをなして・いる。In these figures, reference numeral 1 indicates the rear enclosure (cover member of the heat dissipation part) of the TV, and the cross-sectional shape of the heat dissipation hole part 2 is as shown in FIG. 2 or 3. The top surface has a U-shape 2b as shown in FIG. 2, and an inverted-shape 2c as shown in FIG.

ような心配が々い。If a liquid such as soy sauce is accidentally poured from the top of a TV with the above shape, the arrow shown in Figures 2 and 3 ((
), much of the liquid flows into the U-shape 2 and the inverted-shape 2c, and is repelled, quickly flowing into the enclosure 1.
flows outside. For this reason, there is a great fear that the liquid may flow into the interior through the opening 2a, come into contact with live electrical parts, and ignite, causing a fire.

、天面部はＶ字形２ｔＬ、Ｕ字形２−をむしている。In these figures, reference numeral 1 indicates the rear enclosure (cover member of the heat dissipation part) of the TV, and the cross-sectional shape of the heat dissipation part 2 is as shown in Figs. 5 and 6. As shown by the broken line, heat is released from the inside through the opening 2a to the outside. The top portion has a V-shape 2tL and a U-shape 2-.
従って上部より誤って液体３がかげられても。Therefore, even if liquid 3 is accidentally spilled from the top.
液体はｒ字形２ｄ、Ｕ字形２−に沿って流れ、開口部２

It does not flow into the interior from α.
本発明によれば、誤まって醤油等の液体をテレビ等のハ
ウジングこぼしてしｉりた場合でも垂直上方部に開口部

なりこれによる火災発生の確率を非常に小さくさせる。According to the present invention, even if a liquid such as soy sauce is accidentally spilled onto the housing of a TV or the like, the heat radiation hole does not have an opening in the vertical upper part, making it difficult for the liquid to enter the inside of the device. This greatly reduces the probability of a fire occurring.
このことにより装置の安全性を向上させる効果がある。This has the effect of improving the safety of the device.
また異物の挿入も防止できる効果もあり熱も後方ににげ
