Description

  The present invention relates to a mounting structure for a remote control device.

  A remote control (remote controller) device for remotely operating a device is widely used by being attached to a wall. For example, a remote control device for remotely operating a water heater that supplies hot water to a bathtub, a shower, a hot water tap of a sink or the like is attached to the wall of a bathroom or kitchen.

  This type of remote control device is communicably connected to a device via a lead wire. For this reason, when the remote control device is attached to the wall, it is necessary to connect the lead wire coming out of the remote control device through a hole formed in the wall and to connect to the wiring behind the wall. At the time of this attachment, a slack and bent lead wire may protrude between the case and the wall surface of the remote control device and be sandwiched. Since the lead wire comes out from the back surface of the remote control device, even if the lead wire is sandwiched between the case and the wall surface, it is difficult to see from the eyes of the installation operator. For this reason, the remote control device may be fixed to the wall in a state where the lead wire is sandwiched between the case and the wall surface. In this case, the lead wire may be damaged or disconnected.

  In the conventional remote control device, in order to prevent the lead wire from being caught as described above, there is a device in which a protective pipe is projected on the back surface of the remote control device and the lead wire is passed through the protective pipe ( For example, see Patent Document 1).

Japanese Patent Laid-Open No. 10-42382 (FIG. 1)

  When a protective pipe is protrudingly provided on the rear surface of the remote control device, a hole having a size into which the protective pipe can be inserted must be formed in the wall when being attached to the wall. That is, it is necessary to open a hole having a diameter larger than that of the protective pipe in the wall, which is troublesome. Also, since the attachment position of the remote control device is defined by inserting the protective pipe into the hole opened in the wall, the hole for inserting the protective pipe and the screw hole provided in the wall for fixing the remote control device If the positional relationship is shifted, the screw hole cannot be inserted, and the hole position must be corrected. For this reason, it is difficult to efficiently perform the attaching operation of the remote control device.

  The present invention has been made to solve the above-described problems, while reliably preventing a lead wire from being sandwiched between the case of the remote control device and the wall when the remote control device is attached to the wall, It is an object of the present invention to provide a remote control device mounting structure that can be easily mounted.

  The mounting structure of the remote control device according to the present invention is such that when the remote control device for remotely operating the device is mounted on the wall, a lead wire taken from the inside of the remote control device to the outside on the back side of the remote control device is formed on the wall A mounting structure for passing through the formed hole, comprising a cylindrical projecting member that protrudes rearward from the back side case of the remote control device and has a hollow portion through which the lead wire passes, and when the remote control device is attached to the wall, the projecting member Is configured to retract the protruding member when pressed against the wall.

  According to the present invention, it is possible to reliably prevent the lead wire from being sandwiched between the case of the remote control device and the wall when the remote control device is attached to the wall. Moreover, since the hole to be opened in the wall only needs to be able to pass the lead wire, it can be made small, and therefore, the mounting operation can be performed easily and quickly.

It is the perspective view which looked at the remote control apparatus of Embodiment 1 of this invention from the back side. It is sectional drawing cut | disconnected by the plane of (a) in FIG. 1 in the state which attached the remote control device shown in FIG. 1 to the wall. FIG. 3 is an enlarged view of a portion indicated by B in FIG. 2 (however, the state before the remote control device is attached to a wall). It is sectional drawing in the state which attached the remote control apparatus of Embodiment 2 of this invention to the wall. FIG. 3 is an enlarged view of a portion indicated by C in FIG. 2 (however, the state before the remote control device is attached to a wall).

  Embodiments of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to the element which is common in each figure, and the overlapping description is abbreviate | omitted.

Embodiment 1 FIG.
FIG. 1 is a perspective view of the remote control device according to the first embodiment of the present invention as viewed from the back side. FIG. 2 is a cross-sectional view taken along the plane “a” in FIG. 1 in a state where the remote controller shown in FIG. 1 is attached to a wall. FIG. 3 is an enlarged view of a portion indicated by B in FIG. 2 (however, the state before the remote control device is attached to the wall).

  The remote control device 10 shown in these drawings is installed on a wall in order to remotely control a device such as a water heater. The remote control device 10 is attached to the wall of a bathroom or kitchen when the water heater is remotely operated.

  As shown in FIG. 2, the casing of the remote control device 10 is configured by combining a front case 1 and a back case 2. The remote control device 10 is attached to the wall 7 by fixing the back side case 2 to the wall 7 with screws 6. An electronic circuit board 5 is installed inside the remote control device 10. A lead wire 4 is connected from the electronic circuit board 5 so as to be communicably connected to a target device operated by the remote control device 10. The lead wire 4 is taken out of the remote control device 10 from the inside of the remote control device 10 through a take-out port formed in the back side case 2. A rubber member 15 having a hole through which the lead wire 4 is inserted is fitted into the lead-out port of the lead wire 4 formed in the back side case 2. A through hole 8 for passing the lead wire 4 is formed in the wall 7. The lead wire 4 reaches the back side of the wall 7 through the through hole 8 and is connected to the wiring to the operation target device. A gap between the back side case 2 and the wall 7 is sealed (sealed) by the packing 3. This prevents water and foreign matter from entering the remote control device 10 from the lead wire 4 outlet.

  Before attaching the remote control device 10 to the wall 7, as shown in FIG. 1, a cylindrical (cylindrical) protruding member 11 protrudes rearward from the back side case 2. The lead wire 4 is taken out through the hollow portion of the protruding member 11. As shown in FIG. 3, the rear case 2 is formed with a storage portion 13 having an annular groove in which the protruding member 11 can be stored. A spring 12 as an urging member for urging the protruding member 11 rearward (backward direction of the remote control device 10) is installed in the storage unit 13. Before the remote controller 10 is attached to the wall 7, the protruding member 11 is pushed out by the spring 12, so that the protruding member 11 protrudes rearward as shown in FIG. When the remote control device 10 is attached to the wall 7, the tip of the protruding member 11 is pressed against the wall surface around the through hole 8. Thereby, when the protruding member 11 is pressed by the wall 7, the spring 12 is contracted, and the protruding member 11 is retracted and stored in the storage portion 13.

  According to this embodiment, when the remote control device 10 is attached to the wall 7, the lead wire 4 is inserted into the hollow portion of the protruding member 11, so the lead wire 4 does not fit inside the through hole 8 of the wall 7. Even when it is bent in a slack, the protruding member 11 protrudes to form a space between the wall 7 and the remote control device 10, so that the slack state can be visually recognized and improved. It does not protrude outside the protruding member 11. For this reason, it can prevent reliably that the lead wire 4 is pinched | interposed between the wall 7 and the back side case 2. As shown in FIG. Therefore, it is possible to reliably prevent the remote control device 10 from being fixed while the lead wire 4 is sandwiched between the wall 7 and the back side case 2, and the lead wire 4 from being damaged or disconnected. Further, since the protruding member 11 is retracted by attaching the remote control device 10 to the wall 7, it is not necessary to insert the protruding member 11 into the through hole 8. For this reason, the through-hole 8 formed in the wall 7 may be smaller in diameter than the protruding member 11 and may have a size that allows only the lead wire 4 to pass therethrough. Therefore, the operation of forming the through hole 8 in the wall 7 is also easy. Further, since the protruding member 11 is not inserted into the through hole 8, even if the position of the through hole 8 is slightly shifted, the mounting position of the remote control device 10 is not affected. For this reason, even if the positional relationship between the screw hole of the wall 7 into which the screw 6 is inserted and the through hole 8 is slightly shifted, the remote control device 10 can be attached to the wall 7 without any problem. For this reason, according to the present embodiment, the remote controller 10 can be easily and quickly attached.

  In the illustrated configuration, the surface of the back side case 2 positioned inside the protruding member 11 is formed to be one step lower than the surface of the other back side case 2. Thereby, it can prevent reliably that the lead wire 4 is pinched | interposed between the wall 7 and the back side case 2 inside the protrusion member 11. FIG. Moreover, the packing 3 can be enlarged and the whole surface can be reliably contacted to the wall 7.

  In the present embodiment, the projecting member 11 is made of a hard member, and the projecting member 11 can be advanced and retracted by the spring 12. However, in the present invention, the projecting member 11 is projected by a flexible member such as a bellows. You may comprise a member. When the projecting member is configured by a flexible member, the projecting member itself can be configured to be compressed and retracted when the projecting member is pressed against the wall when the remote control device is attached to the wall. Even if an urging member such as 12 is not used, the same effect as described above can be obtained.

Embodiment 2. FIG.
Next, the second embodiment of the present invention will be described with reference to FIG. 4 and FIG. 5. The description will focus on the differences from the first embodiment described above, and the same or corresponding parts will be denoted by the same reference numerals. The description is omitted. FIG. 4 is a cross-sectional view corresponding to FIG. 2 in the first embodiment in a state where the remote control device according to the second embodiment of the present invention is attached to a wall. FIG. 3 is an enlarged view of the portion indicated by C in FIG. 2 (however, the state before the remote control device is attached to the wall).

  The cylindrical projecting member 16 provided in the remote control device 20 of the present embodiment shown in these drawings is composed of a flexible member formed of an elastic material (for example, elastic foam rubber). The back side case 2 is formed with a storage portion 18 having an annular groove in which the protruding member 16 can be stored. Before the remote control device 20 is attached to the wall 7, the projecting member 16 projects rearward from the back side case 2 as shown in FIG. 5. When the remote control device 20 is attached to the wall 7, when the protruding member 16 is pressed by the wall 7, the protruding member 16 is compressed and retracted, and is stored in the storage portion 18 as shown in FIG. 4.

  According to this embodiment, in addition to the same effects as those of the first embodiment described above, the following effects can also be obtained. In a state where the remote control device 20 is attached to the wall 7, the compressed projecting member 16 is in close contact with the back side case 2 and the wall 7. For this reason, the lead-out port of the lead wire 4 formed in the back side case 2 is sealed (sealed) by the protruding member 16, and water and foreign matter can be prevented from entering the remote control device 20. Thus, in this embodiment, since the protruding member 16 also functions as a sealing member that seals the lead wire 4 outlet, a member such as the packing 3 of the first embodiment can be omitted.

  As shown in FIG. 4, the front case 1 is formed with a boss 17 that protrudes toward the inner surface. The tip of the boss 17 is in contact with the bottom of the storage portion 18 formed in the back case 2. As described above, when the remote controller 20 is attached to the wall 7, the protruding member 16 is pressed against the wall 7 to be compressed, so that the storage portion 18 is pressed by the compression reaction force, and the back side case 2 is Deforms and deforms. In order for the protruding member 16 to function as a seal member, it is necessary to increase the compression reaction force of the protruding member 16 to increase the degree of adhesion. Therefore, if the boss 17 is not provided, the amount of deformation of the back side case 2 increases. There is. On the other hand, in the present embodiment, since the abutting portion where the boss 17 formed in the front case 1 and the storage portion 18 abut is provided, the compression reaction force of the projecting member 16 is changed to the front case 1. It can be received by both the back side case 2. For this reason, the deformation amount of both cases can be reduced.

  In the configuration shown in the figure, the boss 17 is in contact with the storage portion 18, but the boss 17 is not necessarily in contact with the storage portion 18, and may be in contact with the vicinity of the installation location of the protruding member 16. Further, a protrusion such as the boss 17 may be formed not on the front case 1 but on the back case 2. Moreover, you may comprise including the electronic circuit board 5 interposed between the front side case 1 and the back side case 2. As shown in FIG. In short, the same effect as described above can be obtained by providing a contact portion where the front case 1 and the rear case 2 are in contact with each other in the vicinity of the place where the protruding member 16 is installed.
