  In the bathroom remote controller described in Patent Document 1, it is possible to suppress a decrease in microphone sensitivity due to the formation of a water film in the second sound collection hole. However, in the bathroom remote controller attached to the wall surface of the bathroom, hot water applied to the bathroom remote controller may enter between the cover and the case body and adhere to the surface of the case body. There is also a risk of condensation on the surface of the case body. And if the water adhering to the surface of the case main body exists on the water repellent sheet in front of the first sound collecting hole, there arises a problem that the microphone sensitivity is lowered. Further, when the water repellent sheet is not provided in the opening outside the case main body in the first sound collecting hole, the water adhering to the surface of the case main body flows toward the first sound collecting hole and the first sound collecting hole. There is a possibility that a water film is formed in the sound collecting hole. Then, the problem that microphone sensitivity falls by the water film formed in the 1st sound collection hole arises.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a bathroom remote control capable of suppressing a decrease in microphone sensitivity.

  A bathroom remote control that solves the above problems includes a case main body having a first sound collection hole, and a lower part of the case main body that is mounted on the front side of the case main body and below the first sound collection hole.

A first water-preventing rib is provided, and an opening between both end portions of the first water-preventing rib is opened toward the second sound collecting hole.

  According to this structure, it can suppress that the water which flows along the surface of a case main body from upper direction reaches the outer side opening part of a 1st sound collection hole with the 1st moisture prevention rib. Therefore, since it can suppress that water is arrange | positioned at the outer side opening part of a 1st sound collection hole, the fall of microphone sensitivity can be suppressed. Moreover, the opening part between the both ends of the 1st water covering prevention rib surrounding a part of outer side opening part of the 1st sound collection hole is opened toward the 2nd sound collection hole. Therefore, sound can be guided from the second sound collecting hole to the first sound collecting hole by the first moisture-preventing rib. Therefore, the microphone can collect sound more easily through the first sound collection hole and the second sound collection hole, so that the microphone sensitivity can be improved.

In the bathroom remote control, it is preferable that the first sound collecting hole is provided in a front surface of the case body, and the second sound collecting hole is provided in a side wall portion of the cover.
According to this configuration, since the first sound collecting hole is provided in the front surface of the case body and the second sound collecting hole is provided in the side wall portion of the cover, the first sound collecting hole and the second sound collecting hole are provided. The sound holes are different from each other in the vertical and horizontal positions, and the opening directions are different. In such a bathroom remote controller, a first moisture-preventing rib in which an opening between both ends opens toward the second sound collecting hole is provided on the outer periphery of the outer opening of the first sound collecting hole. Thus, the microphone can collect sound more easily through the second sound collection hole and the first sound collection hole. In addition, the second sound collecting hole is not provided on the front surface of the cover where the hot water is easily applied, but is provided on the side wall portion where the hot water is not easily applied compared to the front surface. Therefore, compared to the case where the second sound collecting hole is provided on the front surface of the cover, it is difficult to form a water film on the second sound collecting hole. Therefore, it is possible to suppress a decrease in microphone sensitivity due to the formation of a water film in the second sound collection hole.

  In the bathroom remote controller, the surface of the case main body is provided with a second moisture prevention rib that forms a ridge extending along the first moisture prevention rib on the outer periphery of the first moisture prevention rib. It is preferable.

  According to this structure, it can suppress that the water which flows along the surface of a case main body from upper direction reaches the outer side opening part of a 1st sound collection hole also by the 2nd moisture prevention rib. Therefore, since it can suppress more that water is arrange | positioned in the outer side opening part of a 1st sound collection hole, the fall of microphone sensitivity can be suppressed more.

  According to the bathroom remote control of the present invention, it is possible to suppress a decrease in microphone sensitivity.

It is open toward. Therefore, it is possible to guide the sound from the second sound collection hole 56 toward the first sound collection hole 35 by the first moisture-preventing rib 43. Therefore, the microphone 62 can collect sound more easily through the first sound collection hole 35 and the second sound collection hole 56.

Next, characteristic effects of the present embodiment will be described.
(1) Since it is possible to suppress the water from being disposed in the outer opening of the first sound collecting hole 35 by the first water-preventing ribs 43, it is possible to suppress a decrease in microphone sensitivity. Moreover, since the sound can be guided from the second sound collection hole 56 toward the first sound collection hole 35 by the first moisture prevention rib 43, the microphone sensitivity can be improved.

  (2) The first sound collection hole 35 is provided in the front surface (substrate fixing portion 33) of the case body 30, and the second sound collection hole 56 is provided in the side wall portion 52 of the decorative cover 50. For this reason, the first sound collecting hole 35 and the second sound collecting hole 56 are displaced in the vertical direction and the left-right direction, and have different opening directions (the first sound collecting hole 35 is in the front-rear direction). The second sound collecting hole 56 is opened in the left-right direction). In such a bathroom remote controller 11, the first moisture-preventing rib 43 in which the opening 43 a between both ends opens toward the second sound collecting hole 56 is the outer periphery of the outer opening of the first sound collecting hole 35. Accordingly, the microphone 62 can collect sound more easily through the second sound collection hole 56 and the first sound collection hole 35. In addition, the second sound collection hole 56 is provided in the side wall 52 in the decorative cover 50, not on the front surface (front covering portion 51) where the hot water is easily applied, but on the side wall 52 where the hot water is less likely to be applied than on the front surface. Therefore, compared to the case where the second sound collection hole 56 is provided on the front surface of the decorative cover 50, it is difficult to form a water film in the second sound collection hole 56. Therefore, it is possible to suppress a decrease in microphone sensitivity due to the formation of a water film in the second sound collection hole 56.

It is possible to suppress the water flowing in the direction from reaching the outer opening of the first sound collecting hole 35. Therefore, since it can suppress more that water is arrange | positioned in the outer side opening part of the 1st sound collection hole 35, the fall of microphone sensitivity can be suppressed more.

  (4) The water flowing along the surface of the case body 30 from above is left and right of the first sound emission hole 37 by the second speaker-side moisture prevention rib 46 or the first speaker-side moisture prevention rib 45. Guided on both sides of the direction, it flows downward. Accordingly, the first speaker side moisture prevention rib 45 and the second speaker side moisture prevention rib 46 allow water flowing along the surface of the case body 30 from above to be opened outside the first sound emitting hole 37. It can suppress reaching a part. Therefore, the formation of a water film in the first sound emitting hole 37 can be suppressed.
