Since the bathroom is hot and humid and easily flooded with water, it is an extremely bad environment for electric appliances that dislike moisture, and some active measures are required to operate without causing failure. Bathroom televisions also require such waterproofing and moisture-proofing measures. In order to prevent water and moisture from entering the inside of the television, it was first attempted to enclose the entire television receiver in an airtight case.

[0003]

However, when the entire television receiver is sealed in an airtight case,
Even though the image can be seen through the transparent window, the sound is trapped in the case, making it very difficult to hear. In addition, it is necessary to perform some waterproof treatment on various switches and operation buttons including the power switch, and it has been difficult to reliably perform the waterproof treatment while maintaining durability. These waterproof treatments are technically feasible if the cost does not matter,
There has been a strong demand for cost reduction, and a bathroom television receiver that has sufficient waterproofing measures despite its simple structure and that can clearly hear the sound has not been realized.

[0004] It is an object of the present invention to solve the above-mentioned problems relating to a television receiver for a bathroom.
It is an object of the present invention to provide a television receiver for a bathroom which has a simple structure, has sufficient waterproofness, and can clearly hear sound.
