Japanese Patent Laid-Open No. 2001-112074 JP 2007-123103 A

  In the remote control attached to the wall surface or the like, when water is wiped during cleaning, water enters the main body through the gap between the peripheral edge of the button hole of the main body and the button top. There is a risk of taking.

  On the other hand, by providing a waterproof rib in the portable electronic device described above between the button pad and the front surface of the main body, water enters the main body from the gap between the peripheral portion of the button hole of the main body and the button top. Although a waterproof structure with such a rib for waterproofing is obtained, there is a problem that it is difficult to reduce the thickness of the remote control due to the presence of the waterproof rib, and the button pad and the waterproof structure In order to ensure the adhesion between the ribs and the adhesion between the front of the main unit and the waterproof rib, it is necessary to apply a high compressive load between the button pad and the front of the main unit, and the dimensional accuracy of each member However, there is a problem that the structure becomes complicated.

  An object of the present invention is to provide a simple waterproof structure that can be thinned in an operating device attached to a wall surface or the like.

  An operating device according to a first invention is an operating device attached to a wall surface or the like, and includes a main body and a front panel. The main body accommodates the electrical board in a state along the wall surface and the like, moves in a direction close to the electrical board by applying a pressing load from the front side, and releases the pressing load from the front side. An operation button unit that moves in a direction away from the electrical board is configured. The front panel is fixed to the front surface of the main body, and is formed with a button hole that exposes the front side portion of the operation button portion. A groove extending downward from the lower end of the operation button portion is formed on the front surface of the main body. The groove and the back surface of the front panel constitute a water guide path that guides water that has entered the main body side downward from the gap between the peripheral portion of the button hole and the front side portion of the operation button portion.

  In this operation device, the front panel is fixed to the front surface of the main body constituting the operation button portion, and a groove extending downward from the lower end of the operation button portion is formed on the front surface of the main body. Since the water guide path is configured by the back of the water, water can enter the main body from the gap between the peripheral part of the button hole and the front part of the operation button part when water is wiped during cleaning. Even then, this water is guided downward through the water conduit and drained below the position corresponding to the waterproof required portion of the electrical board. It is possible to prevent intrusion and water on the electrical board. In this way, the waterproof structure in this operating device can be made thinner as much as there is no waterproof rib compared to the conventional waterproof structure with a waterproof rib, and in order to ensure adhesion It is possible to provide a simple structure that does not require a compressive load between the members or requires dimensional accuracy of each member.

  The operating device according to a second aspect of the present invention is the operating device according to the first aspect of the present invention, wherein the front surface of the main body has a gap between the peripheral portion of the button hole and the front side portion of the operation button portion at the position of the upper end of the groove. An aggregating portion is further formed that collects water that has entered the main body side before being led to the groove.

  In this operation device, even when water enters the main body side through the gap between the peripheral portion of the button hole and the front side portion of the operation button portion, this water is guided to the water guide path after being collected in the collecting portion. As a result, even when a large amount of water that exceeds the drainage capacity from the water conduit enters the main body side through the gap between the peripheral part of the button hole and the front side part of the operation button part, Can be guided to the water conduit without entering the main body from the operation button portion.

  An operating device according to a third invention is the operating device according to the first or second invention, wherein the operation button unit is a first operation button unit and a second operation button is disposed below the first operation button unit. And at least an operation button portion. The groove extends from the first operation button portion toward the second operation button portion.

  In this operation device, since the groove extends from the first operation button portion toward the second operation button portion arranged below the first operation button portion, the button hole corresponding to the first operation button portion is formed. Even if water enters the main body side through the gap between the peripheral edge portion and the front side portion of the first operation button, the water does not enter the main body from the first operation button portion, and the lower first through the water guide path. 2 It will be led to the operation button part and will be drained below the part where waterproofing of the electrical circuit board is necessary. Can be prevented.

  An operating device according to a fourth invention is the operating device according to any one of the first to third inventions, wherein the main body includes a substantially box-shaped case and a button constituting a front side portion of the operation button portion. Have. The operation button part is formed integrally with the button, the front surface of the case, the button support part on which the button is disposed, and the button support part and the front surface of the case are elastically formed integrally with the front surface of the case. And an elastic part to be connected. A gap is formed between the button support portion and the front surface of the case as the elastic portion is formed.

  In this operation device, the main body has a case and a button, and the operation button portion has a button, a button support portion, and an elastic portion, and the button support portion and the front surface of the case are formed along with the formation of the elastic portion. A gap is formed between the button hole and the water when the water enters the main body through the gap between the peripheral part of the button hole and the front side part of the operation button part. It has a structure that may further invade. However, this operating device employs a structure in which the front panel is fixed to the front surface of the main body constituting the operation button portion, and a groove extending downward from the lower end of the operation button portion is formed on the front surface of the main body. Since the water guide path is configured by the back of the front panel, when water is wiped off during cleaning, water flows into the main body from the gap between the peripheral edge of the button hole and the front side of the operation button. Even if it penetrates, this water is guided downward through the water conduit without entering the case through the gap between the button support part and the front of the case, and below the part that requires waterproofing of the electrical board. As a result, water can be prevented from entering the main body from the operation button portion and water splashing on the electrical board.

  As described above, according to the present invention, the following effects can be obtained.

  In the first invention, the main body can be made thinner by the absence of the waterproof rib as compared with the conventional waterproof structure using the waterproof rib, and a compressive load is applied between the members in order to ensure adhesion. It is possible to provide a simple structure that does not need to be applied or require dimensional accuracy of each member.

  In the second invention, even when a large amount of water exceeding the drainage capacity from the water guide path enters the main body side from the gap between the peripheral portion of the button hole and the front side portion of the operation button portion, It is possible to guide to the water guide path without entering the main body from the operation button part.

  In the third invention, even if water enters the main body from the gap between the peripheral portion of the button hole corresponding to the first operation button portion and the front side portion of the first operation button, Without intruding into the main body from the button part, it is led to the second operation button part below through the water guide path, and drained below the part that requires waterproofing of the electrical circuit board. It is possible to prevent water from splashing on the electrical board by further entering the main body from the 1 operation button part.

  In the fourth invention, even when water is wiped at the time of cleaning, even if water enters the main body side from the gap between the peripheral portion of the button hole and the front side portion of the operation button, the water is supported by the button. Without entering the case through the gap between the front of the case and the case, it will be guided downward through the water conduit and drained below the part that requires waterproofing of the electrical circuit board. Further intrusion into the main body from the button portion can be prevented from splashing the electrical board.

(2) Waterproof structure of remote control In the remote control 1 having the basic structure as described above, it corresponds to the central button 11 corresponding to the front side portion of the central operation button portion 17 and the front side portion of the cross operation button portion 18. There is a gap between the cross button 12 and the buttons 12 to 16 corresponding to the front side portions of the operation button portions 18 to 22 corresponding to the peripheral portions of the button holes 32 to 36 of the front panel 3. Since there is a gap between them, there is a risk that water may enter the main body 2 side (more specifically, the front side of the front plate 5a) from these gaps when the remote control 1 is wiped with water during cleaning. is there. And when such water intrusion to the main body 2 occurs, this water may further enter the main body 2 from the operation button portions 17 to 22.

  In particular, the operation button portions 17 to 22 such as the remote controller 1 include buttons 11 to 16, button support portions 61, 63, 65, 67, 69, 72, 75, 78, 81, button elastic portions 62a, When the structure having 62b, 64a, 64b, 66a, 66b, 68a, 68b, 70a, 70b, 73a, 73b, 76a, 76b, 79a, 79b, 82a, 82b is adopted, the button elastic portion 62a , 62b, 64a, 64b, 66a, 66b, 68a, 68b, 70a, 70b, 73a, 73b, 76a, 76b, 79a, 79b, 82a, 82b, the button support portions 61, 63, 65, 67 69, 72, 75, 78, 81 and the front surface of the case 5 (more specifically, the front surface of the front plate 5a), a gap is formed. The operation corresponding to the gap between the central button 11 corresponding to the front portion of the portion 17 and the cross button 12 corresponding to the front portion of the cross operation button portion 18 and the peripheral portions of the button holes 32 to 36. When water enters the main body 2 from the gap between the buttons 12 to 16 corresponding to the front side portions of the button portions 18 to 22, there is a possibility that this water may further enter the case 5 through the gap. It is high.

  On the other hand, in the remote controller 1, the water that has entered the main body 2 through the gap between the center button 11 and the cross button 12 or the gap between the peripheral edge of the center button hole 32 and the cross button 12 is the first. By making the shape of the outer peripheral edge of the recess 52 into an arc shape, it is easy to be guided downward along the vicinity of the outer peripheral edge of the first recess 52, and the lower end of the electrical board 4 is connected to the central operation button portion 17 and the cross operation button portion. For the water that has entered the main body 2 side through the gap between the peripheral portion of the lower left button hole 34 and the lower left button 14 so as not to be positioned below the lower end position of the first recess 52 in which the 18 is disposed. 4 so that the lower end of 4 is not located below the position of the lower end of the third recess 54 in which the lower left operation button portion 20 is disposed, and the main body from the gap between the peripheral portion of the lower right button hole 36 and the lower right button 16. 2 For the water that has entered into the first recess 52, the lower end of the electrical board 4 is not positioned below the lower end of the fifth recess 56 where the lower right operation button portion 22 is disposed. The central button 11 and the central button 11 are arranged so that the waterproof part (electronic component mounted on the electrical board 4) of the electrical board 4 is not located below the lower edge, the lower edge of the third recess 54, and the lower edge of the fifth recess 56. Gap between the cross button 12, the gap between the peripheral portion of the central button hole 32 and the cross button 12, the gap between the peripheral portion of the lower left button hole 34 and the lower left button 14, and the peripheral portion of the lower right button hole 36 and the lower right button 16, even if the water enters the main body 2 through the gap between the button 16 and the front of the case 5, the water is allowed to enter the case 5 from the gap between the button support portions 61, 63, 65, 67, 69, 75, 81. Without intrusion, recess 52, Promptly guided to the lower end of the recess 52, 54, 56 through such 4,56, water is to prevent such to the to the electrical component mounting board 4.

  However, regarding the water that has entered the main body 2 through the gap between the peripheral portion of the upper left button hole 33 and the upper left button 13 and the gap between the peripheral portion of the upper right button hole 35 and the upper right button 15, the lower left operation button portion 20 and Since the lower right operation button part 22 is located below the upper left operation button part 19 and the upper right operation button part 21, the lower end of the electrical board 4 is arranged at the second recess 53 in which the upper left operation button part 19 is arranged. It is difficult to prevent the lower end and the lower end of the fourth recess 55 where the upper right operation button portion 21 is disposed from being located below the lower end.

Therefore, in the remote controller 1, on the front surface of the main body 2 (more specifically, on the front surface of the front plate 5a),
A left groove 91 extending downward from the lower end of the upper left operation button portion 19 and a right groove 92 extending downward from the lower end of the upper right operation button portion 21 are formed. As a result, the left groove 91 and the back surface of the front panel 3 are arranged such that the water that has entered the main body 2 side through the gap between the peripheral portion of the upper left button hole 33 and the upper left button 13 corresponding to the front side portion of the upper left operation button portion 19. The right water guide path 9a is formed downward, and the right groove 92 and the back surface of the front panel 3 are formed by the peripheral portion of the right upper button hole 35 and the upper right button 15 corresponding to the front side portion of the upper right operation button portion 21. The right water guide path 9b that guides the water that has entered the main body 2 side from the gap downward is configured. Here, the left groove 91 extends toward the lower left operation button part 20 disposed below the upper left operation button part 19 (first operation button part), and the right groove 92 corresponds to the upper right operation button part 21. It extends toward the lower right operation button portion 22 arranged below the (first operation button portion).

  For this reason, even when water is wiped from the remote control 1 at the time of cleaning, even if water enters the main body 2 from the gap between the peripheral portion of the upper left button hole 33 and the upper left button 13, this water remains in the left water guide path. Even if water enters the main body 2 from the gap between the peripheral edge of the upper right button hole 35 and the upper right button 15 through the right water guide path 9b, the water is guided to the lower left operation button portion 20 through the lower portion 9a. It is led to the lower right lower operation button part 22 and drained below the position corresponding to the waterproof required part of the electrical circuit board 4, so that the operation button parts 19 and 21 enter the main body 2. Further, it is possible to prevent water from entering the electrical board 4 by entering. As described above, in the waterproof structure of the remote controller 1, the main body 2 can be made thinner by the absence of the waterproof rib as compared with the conventional waterproof structure using the waterproof rib, and the adhesion can be ensured. It is possible to provide a simple structure that does not require the application of a compressive load between the members or the dimensional accuracy of each member.

  In addition, since the left groove 91 is connected to the left end of the third recess 54 and the right groove 92 is connected to the right end of the fifth recess 56, the lower operation button portion 20, through the water guide paths 9 a and 9 b, The water guided up to 22 can be quickly guided to the lower ends of the recesses 54 and 56 along the vicinity of the outer peripheral edges of the recesses 54 and 56.

  Further, in the remote controller 1, on the front surface of the main body 2 (more specifically, the front surface of the front plate 5a), the gap between the peripheral portion of the upper left button hole 33 and the upper left button 13 is located at the upper end of the left groove 91. The water that has entered the main body 2 side is collected at the upper end of the right groove 92 and the left collecting portion 93 that collects before guiding the water to the left groove 91, and from the gap between the peripheral portion of the upper right button hole 35 and the upper right button 15 to the main body 2 side. A right aggregating portion 94 that collects the invading water before being led to the right groove 92 is further formed. Here, the left aggregation portion 93 is a groove wider than the left groove 91 formed below the lower end of the second recess 53, and the right aggregation portion 94 is lower than the lower end of the fourth recess 55. The groove is wider than the right groove 92 formed in the above.

  For this reason, in this remote control 1, even when water enters the main body 2 through the gap between the peripheral portion of the upper left button hole 33 and the upper left button 13, Even when water enters the main body 2 through the gap between the peripheral portion of the upper right button hole 35 and the upper right button 15 after the water is collected in the right collecting portion 94, it is guided to the path 9a. As a result, the water guide passage 9b is guided to the main body 2 side from the gap between the peripheral portion of the upper left button hole 33 and the upper left button 13 and the gap between the peripheral portion of the upper right button hole 35 and the upper right button 15. Even when a large amount of water exceeding the drainage capacity from 9b enters, the water can be guided to the water guiding paths 9a and 9b without entering the main body 2 from the operation button portions 19 and 21. That. Further, when adopting a structure in which the front panel 3 is fixed to the front surface of the main body 2 by sticking to the front surface of the main body 2, as in the case of the remote controller 1, in order to realize secure fixing, more specifically, the front surface (more specifically, It is desirable to increase the contact area between the front surface of the front plate 5a and the back surface of the front panel 3. However, since the widths of the grooves 91 and 92 can be reduced by providing the aggregation portions 93 and 94, the front surface of the main body 2 can be reduced. This also contributes to an increase in the contact area between the front panel 3 and the back surface of the front panel 3.
