Description

  The present invention relates to a remote control device.

  Conventionally, a remote controller such as a water heater is installed on a wall surface. Some remote control devices installed on the wall surface do not include a rear case of the remote control device. In some remote control devices that do not include a back case, the back surface of the remote control device is covered with an insulating sheet in order to prevent foreign matter from entering the case from the back side of the remote control device. A remote control device whose rear surface is covered with an insulating sheet is disclosed in, for example, Japanese Patent Laid-Open No. 2002-345124 (Patent Document 1).

JP 2002-345124 A

  In the remote control device whose back surface is covered with an insulating sheet as described in the above publication, for example, water droplets attached to the wall surface during cleaning or the like reach the remote control device through the wall surface and are attached to the back surface of the remote control device. In some cases, the insulation sheet and the case of the remote control device may enter the case. In this case, when the water droplets that have entered the case come into contact with the circuit of the substrate disposed in the case, the circuit of the substrate may be short-circuited, causing the remote control device to fail.

  This invention is made | formed in view of the said subject, The objective is to provide the remote control apparatus which can suppress the penetration | invasion of the water drop into a case.

  The remote control device of the present invention is used by being fixed to a wall. The remote control device includes a case, a substrate, and an insulating sheet. The case has a plate-like portion facing the substrate and a peripheral wall portion surrounding the substrate. The insulating sheet sandwiches the substrate between the plate-like portions and is disposed on the wall side of the substrate. The case includes a claw portion connected to the peripheral wall portion. The nail | claw part has covered the upper end of at least one part of the insulating sheet from the board | substrate opposite side with respect to the insulating sheet.

  According to the remote control device of the present invention, the claw portion covers at least a part of the upper end of the insulating sheet from the side opposite to the substrate with respect to the insulating sheet. For this reason, the nail | claw part can suppress that a water droplet flows into the upper end of at least one part of an insulating sheet. Thereby, it can suppress that a water droplet penetrate | invades in a case from the clearance gap between the upper end of at least one part of an insulating sheet, and a case.

  In the above remote control device, the claw portion protrudes from the peripheral wall portion to the side opposite to the substrate with respect to the insulating sheet and then extends toward the lower end side of the insulating sheet. The lower end of the claw portion is located on the opposite side of the insulating sheet from the substrate, and is located on the lower end side of the insulating sheet with respect to at least a part of the upper end of the insulating sheet. For this reason, a nail | claw part can flow a water drop to the lower end side of an insulating sheet rather than a board | substrate with respect to an insulating sheet, and rather than the upper end of at least one part of an insulating sheet. Thereby, it can suppress that a water droplet penetrate | invades in a case from the clearance gap between the upper end of at least one part of an insulating sheet, and a case.

  In the above remote control device, the claw portion includes an upper surface that is inclined from the peripheral wall portion toward the lower end side of the insulating sheet toward the tip opposite to the substrate with respect to the insulating sheet of the claw portion. For this reason, the nail | claw part can flow a water droplet along the upper surface which inclines to the lower end side of an insulating sheet toward the front-end | tip on the opposite side to a board | substrate with respect to the insulating sheet of a nail | claw part from a surrounding wall part. Thereby, it can suppress that a water droplet accumulates in a nail | claw part and a water droplet flows from the edge part which cross | intersects the front-end | tip of a nail | claw part. Therefore, it can suppress that a water droplet flows from the edge part of a nail | claw part to the upper end of at least one part of an insulating sheet.

  In the above remote control device, the claw portion engages at least a part of the upper end of the insulating sheet. For this reason, it can suppress that a clearance gap produces between a nail | claw part and the upper end of at least one part of an insulating sheet. Thereby, it can suppress that a water droplet penetrate | invades in a case from the clearance gap between a nail | claw part and the upper end of at least one part of an insulating sheet.

  In the above remote control device, the claw portion includes a central portion disposed in the center in the horizontal direction intersecting the vertical direction of the insulating sheet, and dam portions connected to both ends of the central portion in the horizontal direction. The weir portion projects in the vertical direction of the insulating sheet from the center portion. For this reason, the dam part can suppress that a water droplet flows into a horizontal direction from the both ends of a nail | claw part. Thereby, it can suppress that a water droplet flows from the both ends of a nail | claw part to the upper end of at least one part of an insulating sheet.

  In the above remote control device, the case includes a mounting hole for mounting on a mounting plate mounted on the wall. The claw portion is located directly below the mounting hole. Since the mounting hole is pressed by a screw or the like, water droplets collect in the mounting hole. Since the claw portion is located directly below the attachment hole, water droplets collected in the attachment hole flow along the claw portion. Thereby, it can suppress effectively that a water droplet penetrate | invades in a case from the clearance gap between the upper end of an insulating sheet and a case.

  As described above, according to the present invention, it is possible to provide a remote control device that can suppress the intrusion of water droplets into the case.
