Description

  The present invention relates to a wall-mounted remote controller that is used by being installed on a wall surface of a kitchen or other places, such as a remote controller for a hot water supply apparatus.

When installing a remote controller for a hot water supply device on the wall surface of the kitchen, for example, a base member formed by processing a metal plate is fixed to the wall surface of the kitchen, and then attached to the front surface of the base member. A means of attaching is often employed. In this case, as a means for improving the attachment workability of the remote control body, the base member is provided with a locking projection protruding forward, while the rear wall portion of the remote control body has a through-hole shape. There is a means for providing a locking hole (see, for example, Patent Document 1).
According to such a configuration, the remote control body can be hooked to the base member by engaging the locking protrusion of the base member in the locking hole of the remote control body. Therefore, it is not necessary to screw the remote control main body to the base member while supporting the remote control main body by hand, and it is possible to facilitate the mounting operation of the remote control main body.

  However, in the prior art, there are points to be improved as described below.

That is, in many cases, the locking protrusions of the base member are bent, for example, in an L shape when viewed from the side. When the locking protrusions are engaged with the locking holes, It is customary that the entire hole is not blocked and a part of the hole remains open. For this reason, in a state where the remote control is installed on a desired wall surface, there is a risk that insects or the like may enter the remote control main body from the opening portion of the locking hole described above. Such invasion of insects is not preferable from the viewpoint of maintaining the inside of the remote control main body in good hygiene and protecting each part, and it is desired to prevent it appropriately.
As a means for preventing the entry of insects and the like as described above, a locking projection provided on the remote control body may be formed as a through-hole-shaped recess instead of being formed in a through-hole shape. Can be considered. However, when it is going to resin-mold the non-through-hole-shaped recessed part which has the form which can latch the latching protrusion appropriately, it is difficult to remove the mold for resin molding, and the molding is difficult ( (Refer to the description of FIG. 11 described later).

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

1 to 5 show an example of a wall-mounted remote controller to which the present invention is applied.
A wall-mounted remote controller A1 of this embodiment (hereinafter abbreviated as “remote controller A1” as appropriate) is a remote controller for a hot water supply device, and is used by being attached to a wall surface 90 of a kitchen, for example, as shown in FIG. . As shown well in FIG. 2, the remote controller A <b> 1 includes a base member 6 that is fixedly attached to a wall surface 90 and a remote controller body 5. The remote control body 5 has a configuration in which a decorative cover 3 and a rear case cover 4 are assembled to a case 2 that accommodates the circuit board 1.

  The circuit board 1 is configured by mounting a plurality of electric / electronic components constituting a data processing circuit for executing a process for setting operating conditions of a hot water supply device on a board body. On the front portion of the circuit board 1, for example, a display 10 using a liquid crystal display, a contact switch mechanism (not shown) for operation switches, and the like are mounted.

  The case 2, the decorative cover 3, and the rear case cover 4 are all made of resin. The case 2 has a back opening shape, and the circuit board 1 is accommodated and attached to the case 2 from the back opening 22 of the case 2. The case 2 is provided with a transparent window portion 20 and a plurality of operation switches 21 that allow the display portion 10a of the display 10 to be viewed. The decorative cover 3 has a frame shape or a case shape with a rear opening, and is externally fitted to the case 2 from its front side so as to appropriately cover the front and side portions of the case 2. The decorative cover 3 is provided with an opening 30 for exposing or exposing the transparent window portion 20 and the plurality of operation switches 21 of the case 2 to the outside. The decorative cover 3 may be provided with an operation switch 31 different from the operation switch 21 described above.

  The rear case cover 4 is a member that is fitted and attached to the case 2 so as to close the back opening 22 of the case 2 and is located behind the circuit board 1 and has a substantially plate shape that is rectangular in a front view. In a state where the remote control body 5 is assembled, the plate-like portion which is the main part of the rear case cover 4 is the rear wall portion 40 of the remote control body 5. The rear wall portion 40 is provided with first to third cylindrical protruding portions 41 to 43, which will be described later.

  The base member 6 is configured by pressing a metal plate or the like, and is fixed to the wall surface 90 using a screw body 98 inserted through the through holes 60a and 60b. The base member 6 is provided with a plurality of (for example, four) locking protrusions 65 having a substantially L shape in side view and projecting forward from the left and right side edges of the base member 6.

  As clearly shown in FIG. 3, a pair of locking holes 45 and a pair of engaging portions 48 corresponding to the plurality of locking protrusions 65 are formed in the rear wall portion 40. A hole portion 46 (corresponding to an example of the “hole portion for forming an engagement portion” in the present invention and illustrated in an enlarged state in FIGS. 7 to 9) and a terminal opening portion 47 are provided.

  The locking hole 45 is a part for engaging the locking projection 65 and has a slit shape extending in the vertical direction. As shown in FIGS. 4A and 4B, the locking hole 45 is formed to have a vertical width that allows the locking projection 65 to enter the horizontal direction from the rear. When the remote control body 5 is lowered in the state shown in FIG. 4B, the tip of the locking projection 65 is locked to the upper edge of the locking hole 45 as shown in FIG. It is possible to make it. As shown in FIG. 3, the locking hole 45 is preferably formed with a narrower width in the upper part than in the lower part, and a locking projection 65 is formed on the upper edge of the locking hole 45. When locked, the remote control main body 5 is configured so that a large gap (rattle) does not occur in the locking hole 45 in the left-right horizontal direction. In addition, the remote control body 5 is configured not to rattle in the front-rear direction. However, as shown in FIG. 4C, a part of the lower side of the locking hole 45 remains open. This opening part may become an approach path for insects and the like.

  As clearly shown in FIGS. 2 and 4, the rear wall portion 40 is provided with a plurality of first cylindrical projecting portions 41. The first cylindrical projecting portion 41 has a substantially rectangular tube shape that projects forward from the periphery of the locking hole 45 and surrounds the periphery of the front region of the locking hole 45. The first cylindrical protrusion 41 has a tip opening 41a. The tip opening 41a is formed by the tip of the first cylindrical protrusion 41 being in contact with the rear surface portion of the circuit board 1. It is blocked by the circuit board 1. As a result, even if an insect enters the locking hole 45, it is possible to prevent further entry into the remote control body 5. The first cylindrical projecting portion 41 is in contact with a portion that avoids the component mounting area in the vicinity of the left and right side edges of the circuit board 1.

The pair of engaging portions 48 provided on the rear wall portion 40 can be elastically deformed in the front-rear direction of the remote control main body 5 and have a convex portion 48a protruding rearward. The engaging portion 48 is shown in FIG.
As shown, when the locking projection 65 is inserted into the locking hole 45 of the remote control main body 5, it is pushed forward by the base member 6 as indicated by an arrow N1. Next, as shown in FIG. 4C, when the remote controller body 5 is slid downward and the convex portion 48a is located below the lower edge portion 61 of the base member 6, the lower portion of the engaging portion 48 is The convex portion 48 a is engaged with the lower edge portion 61 of the base member 6 by being displaced rearward by the elastic restoring force. When such an engagement occurs, it becomes difficult to move the remote control body 5 upward relative to the base member 6, and the state in which the locking projection 65 is locked to the upper edge portion of the locking hole 45 is formed. It can be maintained properly.

  The engaging portion 48 is formed by providing a U-shaped or substantially U-shaped hole 46 in the rear wall 40, and insects and the like enter the remote control body 5 from the hole 46. As a means for preventing this, a second cylindrical protrusion 42 is provided (in FIG. 4, the first and second cylindrical protrusions 41, 42 are shown on the same cross section for convenience, Only the lower side of the cylindrical protrusion 42 is shown in FIG. 2. This is also true for FIG. The second cylindrical protruding portion 42 is a rectangular tube with a tip opening that protrudes forward from the periphery of the hole 46 and surrounds the periphery of the front region of the hole 46. The tip of the second cylindrical projecting portion 42 is also in contact with the rear surface portion of the circuit board 1 in the same manner as the first cylindrical projecting portion 41, and the tip opening 42 a is blocked by the circuit board 1. Yes. The second cylindrical projecting portion 42 is in contact with a portion in the vicinity of the lower edge of the circuit board 1 that avoids the component mounting area.

  As shown in FIG. 5, the terminal opening 47 is a part for exposing the terminal portion 15 provided on the rear surface portion of the circuit board 1 to the rear side of the rear wall portion 40. The wiring cord C connected to the terminal portion 15 is passed through the opening portion 64 of the base member 6 and the opening portion 91 provided in the wall portion 9, and is connected to the hot water supply device. As shown in FIG. 3, the terminal opening 47 is provided in a part of the wiring cord routing recess 40 a provided in the rear wall 40. In the present embodiment, insects and the like are also prevented from entering the remote control body 5 from the terminal opening 47, and as a means for that purpose, a third cylindrical protrusion 43 is provided as shown in FIG. It has been. The third cylindrical protrusion 43 protrudes forward from the periphery of the terminal opening 47 and has a rectangular tube shape with a tip opening that surrounds the periphery of the front region of the terminal opening 47. The tip of the third cylindrical protrusion 43 is also in contact with the rear surface portion of the circuit board 1 in the same manner as the first and second cylindrical protrusions 41 and 42, and the tip opening 43 a is the circuit board 1. It is blocked by.

  The rear wall portion 40 is also provided with recesses 49a and 49b for avoiding interference with the screw body 98. Unlike the locking holes 45, these recesses 49a and 49b do not have to be structured so that the locking projections 65 can be locked, and the head of the screw body 98 simply enters. What is necessary is just to be formed so that it may obtain. Therefore, although these recesses 49a and 49b are non-through holes, there is no problem that they are difficult to mold.

  Next, the operation of the remote controller A1 will be described.

  First, as described with reference to FIG. 4, the procedure for attaching the remote control body 5 to the base member 6 is to engage the locking projections 65 of the base member 6 in the locking holes 45 of the remote control body 5. After that, it is only necessary to slide down the remote control main body 5. By this operation, the remote control body 5 can be hooked on the base member 6. Further, since the engaging portion 48 engages with the lower edge portion 61 of the base member 6, the remote control main body 5 is prevented from being lifted, so that the latch mounting state of the remote control main body 5 with respect to the base member 6 is inadvertently released. It can also be prevented.

In the mounted state of the remote controller A1 shown in FIG. 4C, the lower part of each locking hole 45 is not closed by the locking projection 65 and is in an open state. There is a possibility that, for example, an insect enters the one cylindrical protrusion 41. On the other hand, the first cylindrical protruding portion 41 enters the first cylindrical protruding portion 41 because the tip opening portion 41a is closed by the circuit board 1 as described above. It is possible to appropriately prevent the insects that have traveled further into the remote control body 5. Of course, entry of dusts other than insects can be prevented. The rear wall portion 40 of the remote control main body 5 is also provided with a hole portion 46 and a terminal opening portion 47 as holes other than the locking hole portion 45, but the second portion provided corresponding to these holes is also provided. Since the tip openings 42a and 43a of the third cylindrical protrusions 42 and 43 are blocked by the circuit board 1, insects or the like may enter the remote control body 5 from these portions. Is prevented. For this reason, the interior of the remote control body 5 can be maintained in a good state of hygiene and can be appropriately protected.

The circuit board 1 is used as means for closing the front end openings 41a to 43a of the first to third cylindrical projecting portions 41 to 43, and it is not necessary to separately use a dedicated member. Therefore, the configuration is reasonable, and the complexity of the structure can be appropriately avoided. Moreover, since all the 1st thru | or 3rd cylindrical protrusion parts 41-43 should just be formed in the front-end | tip opening shape, the shaping | molding is also easy.
FIG. 11 shows a comparison (virtual comparison) with the present invention. In this comparison, the first cylindrical protrusion 41A is formed as a non-opening concave portion having a wall portion 410 at the tip. However, according to such a configuration, the downward convex portion 45a for locking the locking protrusion 65 to the upper edge portion of the locking hole 45 is formed while forming the first cylindrical protruding portion 41A. Further, it is not easy to form (it is difficult to remove a mold for resin molding). On the other hand, if the first cylindrical projecting portion 41 has a tip opening shape as in the present embodiment, there is no such inconvenience, the resin molding can be facilitated, and the manufacturing cost can be reduced. it can.

  6 to 10 show other embodiments of the present invention. In these drawings, elements that are the same as or similar to those in the above embodiment are denoted by the same reference numerals as those in the above embodiment, and redundant description is omitted.

  In the remote control A2 shown in FIG. 6, the case 2 is provided with a wall portion 25 that protrudes inward from the side wall of the case 2, and the tip of the first cylindrical protrusion 41 located near the lower portion of the remote control main body 5, for example, is a wall. The front end opening 41 a of the first cylindrical projecting portion 41 is closed by the wall portion 25 in contact with the rear surface of the portion 25. The same applies to the second cylindrical protrusion 42, and the tip opening 42 a is closed by the wall 25.

  Even when the front end openings 41a and 42a of the first and second cylindrical projecting portions 41 and 42 are closed using the wall portion 25 provided in the case 2 as in this embodiment, It is possible to appropriately prevent insects and the like from entering the remote control body 5. As can be understood from the present embodiment, in the present invention, a wall provided separately in the remote control main body instead of the circuit board as a means for closing the distal end openings of the first and second cylindrical protrusions May be used. If the first and second cylindrical projecting portions 41, 42 are provided so as to be biased toward the outer peripheral edge of the rear wall 40, the wall 25 is also biased toward the outer peripheral edge of the remote control body 5. It is sufficient to provide it, which is preferable in reducing the size of the wall portion 25.

In the remote control A3 shown in FIG. 7, a pair of elastically deformable portions 51 for generating a collision sound are provided on the rear wall portion 40 (plate portion of the rear case cover 4) of the remote control main body 5. The elastically deformable portion 51 is a portion for generating a predetermined sound when the remote control main body 5 is appropriately attached to the base member 6 so that the attaching operator can detect it. The elastically deformable portion 51 has, for example, an L shape when viewed from the front, and is formed by providing a slit 52 having a form in which two L-shaped slits are connected in series on the rear wall portion 40. The upper part of the elastically deformable part 51 is connected to the rear wall part 40 and can be elastically deformed in the front-rear thickness direction of the rear wall part 40. Convex portions 51 a and 51 b are formed on the upper and lower portions of the elastically deformable portion 51. As shown in FIG.7 (c), the height H1 of the convex part 51a is made higher than the height H2 of the convex part 51b.

  As a means for preventing insects and the like from entering the remote control main body 5 from the slit 52, the rear wall portion 40 is provided with a fourth cylindrical projecting portion 44. The fourth cylindrical protrusion 44 protrudes forward from the periphery of the slit 52 and has a cylindrical shape with a front end opening surrounding the periphery of the front region of the slit 52. Although not shown in the drawings, unlike the present embodiment, the fourth cylindrical projecting portion 44 has a second cylindrical projecting portion 42 provided corresponding to the hole 46 forming the engaging portion 48. And the second and fourth cylindrical projecting portions 42 and 44 can be integrated (formed as one cylindrical projecting portion). The fourth cylindrical projecting portion 44 abuts on the rear surface portion of the circuit board 1, and the tip opening 44 a is closed by the circuit board 1.

  In the remote control A3 of the present embodiment, as shown in FIG. 8A, when the locking projections 65 of the base member 6 are engaged with the locking holes 45 of the remote control main body 5, the same operation is performed. As shown in FIGS. 2B and 2C, the convex portion 51a of the elastically deformable portion 51 comes into contact with the base member 6 and is pressed forward. For this reason, the elastically deformable portion 51 bends forward, and a gap having a dimension L <b> 3 is generated between the convex portion 51 b and the base member 6. Next, as shown in FIG. 8D, when the remote control body 5 is slid down relative to the base member 6, the engaging portion 48 is moved to the base member 6 as shown in FIGS. At substantially the same timing as engaging with the lower edge portion 61, the convex portion 51 a of the elastically deformable portion 51 is positioned below the lower edge portion of the base member 6. The lower part swings backward by the elastic restoring force. Then, the convex part 51b collides with the base member 6 vigorously, and a collision sound is generated. When the remote controller A3 is installed on the wall surface 90, it is difficult to confirm by visual inspection from the outside whether or not the engaging portion 48 and the base member 6 are properly engaged. On the other hand, according to the present embodiment, by confirming the collision sound when the convex portion 51 b of the elastically deformable portion 51 collides with the base member 6, the engaging portion 48 can be appropriately applied to the base member 6. It is possible to detect the engagement, and to perform the attachment work of the remote controller A3 more accurately.

  In the present embodiment, a pair of elastically deformable portions 51 are provided on the left and right sides, and a collision sound caused by each of the pair of elastically deformable portions 51 can be generated simultaneously. However, instead of this, the collision sound may be intentionally shifted. As one means for that purpose, for example, the left and right elastically deformable portions 51 and 51 are different from each other in the horizontal lengths L1 and L2 of the pair of left and right elastically deformable portions 51 shown in FIG. With 51, a means such as making the stroke at the time of elastic restoration from the bending deformation state different can be adopted. According to such a configuration, when both of the pair of engaging portions 48 are properly engaged with the base member 6, a sound in which the convex portion 51 b collides with the base member 6 at that time can be heard twice in succession. Thus, it is easier to check the collision sound.

  In the remote control A4 shown in FIG. 9, the portion 69 of the base member 6 with which the convex portion 51b of the elastically deformable portion 51 for generating a collision sound contacts is in addition to the base member 6 via the narrow-width portion 68. It is configured to be connected to the part. According to such a structure, when the convex part 51b collides with the above-mentioned part 69, this part 69 becomes easy to vibrate, Therefore A collision sound can be enlarged and the sound can be heard more easily.

In the remote control A5 shown in FIG. 10, a protrusion-like elastically deformable portion 54 protruding rearward is provided on the rear wall portion 40 of the remote control main body 5, and this elastically deformable portion 54 is provided on the base member 6. The long hole 67 has been entered. The elastically deformable portion 54 has a halved portion near the tip through a slit 54a extending in the axial direction, and can be expanded and contracted. The long hole 67 extends in the vertical direction, but the width of the lower portion 67a is made larger than that of other portions.

  In this embodiment, as shown in FIG. 10A, in the state where the locking projection 65 is engaged with the locking hole 45, as shown in FIG. 54 is compressed in the long hole 67. Next, as shown in FIG. 6C, when the remote control main body 5 is lowered and the engaging portion 48 engages with the lower edge portion 61 of the base member 6, at that time, as shown in FIG. The elastically deformable portion 54 is located at the lower portion 67a of the long hole 67 and returns to its original natural state. At this time, the elastically deformable portion 54 collides with the base member 6 and a collision sound is generated. According to such a configuration, unlike the embodiment shown in FIGS. 7 to 9, as a means for generating a predetermined collision sound, the rear wall portion 40 of the remote control main body 5 has an entry route such as an insect. It is not necessary to provide a through-hole that may become a problem, and it is possible to simplify measures for preventing entry of insects and the like.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of each part of the wall-mounted remote controller according to the present invention can be modified in various ways within the intended scope of the present invention.

  In the present invention, when the tip of the first cylindrical protrusion is brought into contact with the circuit board (or a wall surface instead thereof), for example, a relatively soft resin layer having elasticity is provided on the circuit board, You may make it contact | abut the front-end | tip of a 1st cylindrical protrusion part to the said resin layer. According to such a structure, the effect which makes it hard to produce a clearance gap between a 1st cylindrical protrusion part and a circuit board can be anticipated. This also applies to the second and third cylindrical protrusions.

  In the present invention, the first cylindrical protrusion does not necessarily have to be in contact with the circuit board (or a wall surface instead of this), and a minute gap (a gap having a dimension capable of preventing entry of insects or the like) between them. ) Are formed so that they are close to each other. Even with such a configuration, invasion of insects and the like can be prevented, the object of the present invention can be achieved, and the tip opening of the first cylindrical protrusion is substantially blocked, so It is included in the technical scope of the invention. This also applies to the second and third cylindrical protrusions.

  The specific form, number, arrangement, and the like of the locking protrusions and the locking holes in the present invention are not limited. In the remote control according to the present invention, the remote control main body is supported by being hooked to the base member, but in addition to this, other support means (screwing means or the like) may be used in combination. For example, the upper part of the remote control body is hooked to the base member by the engaging action of the locking projection and the locking hole, while the lower part of the remote control body is screwed to the base member. It is also possible to adopt a configuration such as being fixed.

  The remote control body referred to in the present invention is not limited to a combination of a case that accommodates a circuit board, a decorative cover, and a rear case cover.
