Description

The present invention relates to an electronic device for a bathroom such as a bathroom television fixed to a wall surface in the bathroom.

Conventional bathroom electronic devices of this type are covered with a waterproof housing to prevent hot water in the bathroom from entering the inside. However, in order to receive signals from the outside and power supply from the outside, the harness extends from the inside of the housing to the outside. The part where this harness extends is inferior in waterproofness to the waterproofness of other parts of the housing, so waterproof measures such as packing should be used to prevent hot water in the bathroom from reaching the extended part. There is a need to do.

For example, in the bathroom TV, when the bathroom TV is fixed to the wall surface in the bathroom, a metal bracket for fixing is fixed to the wall surface, and the bathroom TV is fixed to the bracket. A harness is extended from the back of the bathroom TV, and the harness is inserted through a through hole provided in the wall surface. An annular sponge-like packing surrounding the extension portion is provided so that the hot water in the bathroom does not reach the extension portion of the harness. Then, when the bathroom TV is fixed to the wall surface, the packing is compressed to seal the hot water in the bathroom so that it does not reach the extension portion. Further, a caulking agent is applied to the outer peripheral edge of the bathroom TV to fill the gap between the outer peripheral edge and the wall surface. In this way, the caulking agent on the outer periphery of the bathroom TV and the sponge-like packing ensure double waterproofing, but in order to further improve the waterproofness, the caulking agent is applied to the outside of the sponge-like packing. In some cases, the bathroom TV is mounted on the wall surface in the state of being in the state, and the applied caulking agent is sandwiched between the back surface of the housing of the bathroom TV and the wall surface when the bathroom TV is mounted (for example, Patent Document). See 1).

JP-A-2018-74276 (Fig. 1)

The work of applying the caulking agent to the outside of the packing is performed by the contractor at the site, but at that time, the state in which the caulking agent is applied may differ depending on the skill of the contractor. Further, if the amount of the caulking agent applied is not appropriate, the caulking agent may be peeled off from the housing of the bathroom television after the applied caulking agent is cured.

Therefore, in view of the above problems, it is an object of the present invention to provide a bathroom electronic device in which the state of application of the caulking agent does not differ depending on the contractor and the cured caulking agent does not easily come off from the housing of the electronic device. And.

In order to solve the above problems, the bathroom electronic device according to the present invention is a bathroom electronic device that is surrounded by a waterproof housing and is fixed to the wall surface of the bathroom, and extends from the back surface of the housing. When the housing is fixed to the wall surface with the harness inserted through the through hole formed in the wall surface, the housing is sandwiched between the back surface of the housing and the wall surface and compressed, and the hot water in the bathroom is discharged. In the case where the packing is provided so as not to reach the through hole, the annular caulking agent application range surrounding the packing is displayed on the back surface of the housing, and the surface roughness of the caulking agent application range is indicated on the housing. It is characterized by making it rougher than the surface roughness of other parts of the back surface to make it difficult for the caulking agent to come off.

By showing the caulking agent application range, the caulking agent can be surely applied to an appropriate range even if the skill of the contractor is different. Further, by making the surface roughness of the caulking material application range rougher than the surface roughness of other parts, the cured caulking agent is less likely to be peeled off from the caulking agent application range.

As is clear from the above description, according to the present invention, the caulking agent can be reliably applied to an appropriate range, and the applied caulking agent is less likely to be peeled off from the housing after being cured.

With reference to FIG. 1, W is the wall surface of the bathroom, and the bathroom television 1 which is an electronic device is fixed. Specifically, the bathroom TV 1 is not directly fixed to the wall surface W, but a sheet metal bracket 4 is fixed to the wall surface W as shown in FIG. 3, and the bathroom TV 1 is attached to the bracket 4. Will be fixed to the wall surface W.

With reference to FIGS. 2 and 3, four engaging pieces 41 bent forward are provided on the upper portion of the bracket 4. And, at the lower part of the bracket 4, two fixing pieces 42 which are also bent forward are provided. On the other hand, on the back surface of the bathroom television 1, as shown in FIG. 2, four engaging windows 11 are provided at the upper part and two fixed windows 12 are provided at the lower part.

When the bathroom TV 1 is brought closer to the bracket 4 from the front while the bracket 4 is fixed to the wall surface W, the four engaging pieces 41 are each inserted into the engaging window 11, and the two fixed pieces 42 are inserted. Is inserted into the fixed window 12. Then, with the bathroom TV 1 pressed against the wall surface W, the fixing piece 42 is fixed to the housing of the bathroom TV 1 from below the fixing window 12 using screws. Then, the bathroom TV 1 is pulled downward by the tightening force of the screw, the engaging piece 41 is brought into close contact with the upper part of the inner surface of the engaging window 11, and the bathroom TV 1 is fixed to the bracket 4.

An extension portion 13 of the harness is provided on the back surface of the bathroom television 1, and a packing 2 surrounding the extension portion 13 is attached in advance to the back surface of the bathroom television 1. The packing 2 is made of a foam material and is compressionally deformed when subjected to external pressure. Therefore, when the bathroom TV 1 is pressed against the wall surface W when the bathroom TV 1 is attached to the bracket 4, the packing 2 is compressed and adheres to the wall surface W so that the hot water in the bathroom does not reach the extension portion 13. Function. Reference numeral 14 denotes a ventilation seal, which is attached so as to cover the through hole formed in the housing of the bathroom TV 1, and functions to make the pressure in the housing of the bathroom TV 1 equal to the atmospheric pressure.

As shown in FIG. 4, when the bathroom TV 1 is fixed to the bracket 4, a caulking agent 52 is applied to the outer peripheral edge of the bathroom TV 1 to prevent hot water in the bathroom from flowing into the back surface of the bathroom TV 1. Even if hot water flows into the back side of the bathroom TV 1, the packing 2 is waterproofed so that the flowing hot water does not enter the range surrounded by the packing 2. Then, in order to further improve the waterproof property, when the bathroom TV 1 is attached to the bracket 4, the caulking agent 51 is applied so as to surround the packing 2, and the hot water flowing into the back surface of the bathroom TV 1 is packed. Before reaching 2, it was made to be blocked by the caulking agent 51.

As the range to which the caulking agent 51 is applied, the caulking agent application range 3 is displayed on the back surface of the bathroom television 1. Therefore, the contractor may apply the caulking agent 51 evenly over the entire area of the caulking agent application range 3. The surface roughness of the caulking agent application range 3 is rougher than that of other parts on the back surface of the bathroom television 1 due to the embossing. Therefore, when the caulking agent 51 is applied to the caulking agent application range 3, the caulking agent 51 adheres more firmly to the caulking agent application range 3 and can reduce the possibility of peeling after curing.

By the way, the means for roughening the surface roughness of the caulking agent application range 3 is not limited to the above-mentioned grain processing, and if the adhesive strength of the caulking agent is stronger than the adhesive strength in other parts, it is specific. It is not limited to means.

The present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the gist of the present invention.
