JP2012-95205A

  By the way, a circuit board is installed in the device housing of the remote controller, and a display element, a switch, a processor, etc. are mounted on the circuit board. Therefore, the fixing of the fixing metal fittings on the device housing and the wall surface and the fixing structure thereof are restricted by the arrangement of components on the circuit board side.

  If a back cover is installed as a member that closes the back side of the device housing, the height in the thickness direction of the device main body from the wall surface is required to separate the back member and the circuit board from the fixing brackets. Only the number of parts increases.

In view of the above problems, an object of the present invention is to reduce the number of parts, simplify the mounting structure, and facilitate the assembly and mounting work.

In order to achieve the above object, according to one aspect of the remote control device of the present invention, a fixing bracket attached to a wall surface, a front plate, and a frame portion that surrounds a peripheral edge of the front plate are attached to the fixing bracket. a device housing that, in the device housing, towards the inside of the frame portion from a position retracted to the front side from the rear edge of the apparatus housing, a and a circuit board attached to the back surface side of the front plate is formed on the non-overlapping ranges, e Bei fixing portion facing the fixing bracket, and insert the engagement protrusions of the mounting brackets to the engagement hole of the fixing portion, wherein the hook portion of the engagement protrusion An insertion/removal mechanism portion that engages with the engagement hole and fixes the device housing to the fixing metal piece so as to be insertable and removable.

  In the above remote controller, the device housing may be a molded body of synthetic resin integrally provided with the fixing portion.

  In the remote control device, when the insertion/removal mechanism part is mounted on the device housing, the elastic projection provided on the fixing part is engaged with the locking hole of the fixing metal fitting and is maintained in a pressed state. An elastic restoring force may be applied to the fixing portion.

The above remote controller may have one or more remote controller functions selected from a plurality of remote controller functions provided in the bathroom remote controller installed in the bathroom.

According to the present invention, the following effects can be obtained.
(1) The device housing is provided with a fixing portion facing the fixing metal fittings, and an insertion/extraction mechanism portion for fixing the fixing metal fittings. It is possible to omit the back member and the back cover that close the back surface of the device housing, and it is possible to reduce the number of parts.

  (2) Since there is an insertion/extraction mechanism part that fixes the device case to the fixing bracket while avoiding the circuit board arranged in the device case, there are restrictions on the circuit board in fixing the device case and the fixing bracket. In addition, by simplifying the mounting structure, not only manufacturing and assembling but also mounting and mounting work can be facilitated.

(3) The remote control device can be flattened, and the protrusion from the wall surface can be reduced.
