Description

  The present invention relates to a bathroom-mounted remote control, wall packing, and a water-proof / drainage structure for a bathroom-mounted remote control, and more particularly to a structure having waterproof and drainage functions in a remote controller for a water heater installed in a bathroom.

  As shown in FIG. 9 (a), when a remote controller of a water heater is attached to the wall surface of the bathroom, water such as water droplets or water vapor (hereinafter referred to as water droplets) does not enter the housing from the rear surface of the remote controller housing. A packing a made of an elastic member having a specific shape and a thickness of about several millimeters (specifically, a sponge-like member) is affixed to a predetermined position (see FIG. 9B) on the rear surface of the housing. In this state, the remote control a is attached to the wall surface of the bathroom.

  More specifically, an annular projecting portion c to which a stay pipe (not shown) is attached when the remote control b is attached to the bathroom wall surface is provided on the rear surface of the remote control b housing. Inside of the through hole (specifically, an electrical wire insertion hole d for inserting an electrical wire (not shown) such as a remote control cable extending from the electrical board inside the housing, and the interior of the housing) Ventilation holes e) are provided so as to penetrate through the rear surface of the housing.

  On the other hand, the wall packing a surrounds the annular portion g having an opening f having substantially the same diameter as the protruding portion c of the rear surface of the housing in accordance with the shape of the rear surface of the housing as described above. The adhesive layer is formed on the front and back surfaces of the annular portion g and the frame portion h (the portion of the adhesive layer is indicated by hatching in the figure).

  When the remote controller b is attached to the bathroom wall surface, the position of the opening f of the wall packing a is set so that the annular portion g of the wall packing a covers the periphery of the protrusion c on the back surface of the housing. In accordance with the position of c, in this state, one surface of the wall packing a is adhered to the back of the housing, and the other surface is adhered to the bathroom wall against the elasticity of the wall packing a. Caulking is applied to the outer peripheral portion of the remote control b (specifically, between the remote control b and the bathroom wall surface).

  As described above, in the conventional construction method, the gap formed between the housing rear surface and the bathroom wall surface is closed by the caulking applied to the outer periphery of the remote controller b and the wall packing a attached to the rear surface of the remote controller b. This prevents water droplets or the like from entering the housing from the through holes d and e.

  However, such a configuration has the following problems, and improvements have been desired.

  That is, the wall packing a used in the above-described conventional construction method is as thin as several millimeters, and the whole is composed of a sponge-like soft member, or a frame portion formed by the frame portion h. Due to the narrow width of the sheet, there is a tendency that distortion or twisting is likely to occur when bonding to the back of the casing of the remote control b, and wrinkles are likely to occur on the bonding surface. On the other hand, this type of remote control b may be attached to the bathroom wall surface without attaching the above-mentioned stay pipe in relation to the construction site. In such a case, the above-mentioned caulking is insufficient or the caulking is deteriorated. If a water droplet or the like enters between the remote control b and the bathroom wall surface, the water droplets pass through the wall packing trap generated during the construction to the rear surface of the remote control b housing (specifically, in the through holes d and e). There was a problem of infiltration.

  In addition, as a convenience method for preventing the occurrence of wrinkles as described above, an operator may cut a part of the wall packing a (for example, the upper end portion) during construction. When a notch is made in the water, intrusion of water droplets or the like is caused from the incised portion. Therefore, even though generation of wrinkles can be suppressed, invasion of water droplets or the like cannot be prevented.

  When water droplets or the like enter the gap between the remote controller b and the bathroom wall surface due to the above-described circumstances, in the conventional wall packing a, the infiltrated water droplets or the like are formed on the outer peripheral surface of the protrusion c of the remote control b and the opening of the wall packing a. There is a problem that water droplets or the like accumulated in the gap easily enter the inside of the casing of the remote control b from the through holes d and e. .

  The present invention has been made in view of the above-described conventional problems, and the object of the present invention is to provide a bathroom-installed remote control that is easy to perform construction work and has a high effect of preventing intrusion of water droplets and the like into the housing. Another object of the present invention is to provide a wall packing and a drainage prevention structure for a bathroom-mounted remote controller using these.

A through-hole leading to the inside of the housing is formed inside the projecting portion, and a drainage groove for draining water droplets entering between the rear surface of the housing and the bathroom wall surface surrounds the projecting portion. In the annular shape, the projection has a predetermined length in the left-right direction at a predetermined position inside the annular drain groove and below the protruding portion, and a part of the annular drain groove is formed in the annular drain groove. A second drainage groove that is in communication is formed.

  And, as a preferred embodiment thereof, water drops or the like that have a predetermined length in the left-right direction below the annular protrusion and inside the annular drain groove and that have entered the groove A third drainage groove having an inclined portion for guiding to the second drainage groove or the annular drainage groove and communicating with the second drainage groove or the annular drainage groove is formed. .

  And the said inclination part forms the full length or a part of said 3rd drainage groove in the upward substantially circular arc shape so that it may be located in substantially equal distance from the outer peripheral wall of the said protrusion part, It is characterized by the above-mentioned. .

  Furthermore, a drainage hole communicating with the annular drainage groove and penetrating through the surface of the housing is provided below the annular drainage groove.

On the other hand, the wall packing according to the present invention is a wall packing interposed between the above-described bathroom-installed remote controller and attached to the bathroom wall surface, and the packing body is composed of a flat plate member having elasticity. A main hole having an opening into which the annular protrusion can be fitted in the packing body, and communicated with the main hole between the inner peripheral surface of the main hole and the outer peripheral wall of the annular protrusion. And a guide hole for guiding the water droplets or the like that have entered into the second drainage groove or the third drainage groove is formed. Preferably, the guide hole has a substantially rectangular opening shape.

  Moreover, the wall packing of this invention is comprised as an other suitable embodiment with the plate-shaped member which a packing main body has elasticity, and has an opening part which can fit the said cyclic | annular protrusion part in this packing main body. A main hole and a guide hole that communicates with the main hole and guides water droplets or the like that have entered between the inner peripheral surface of the main hole and the outer peripheral wall of the annular protrusion to the outside of the packing body are formed. It is characterized by being.

  The packing body is formed with an inclined portion at the upper end thereof, and by this inclined portion, water drops or the like that have entered from the upper side and reached the upper end of the packing body are either left or right side surfaces of the wall packing, or one of the side surfaces. It is comprised so that it may be guided to.

  Further, the packing body is entirely composed of a sponge-like pad, and an adhesive layer is formed on at least one of the front and back surfaces except for the vicinity of the upper end of the packing body.

  Further, in the bathroom remote control drainage structure according to the present invention, the above-described wall packing is bonded to the rear surface of the above-described bathroom-mounted remote controller, and the other surface of the wall packing is bonded to the bathroom wall surface. It is characterized by.

  According to the present invention, the bathroom-mounted remote control has a protruding portion with an outer contour annularly formed on the rear surface of the casing, and a through-hole leading to the inside of the casing is formed inside the protruding portion. A drainage groove for draining water droplets or the like entering between the back of the body and the bathroom wall surface is formed in an annular shape so as to surround the projection, and below the projection and inside the annular drainage groove A second drainage groove having a predetermined length in the left-right direction and a part of which communicates with the annular drainage groove is formed at a predetermined position. A water droplet or the like having a predetermined length in the left-right direction at a predetermined position below the protrusion and inside the annular drainage groove, and entering the groove into the second drainage groove or the annular drainage groove. The second drainage groove or the annular drainage groove having an inclined portion for guiding A third drainage groove that communicates is formed, and a packing body of the wall packing has a main hole having an opening into which the annular protrusion can be fitted, and communicates with the main hole. A remote control is provided with a guide hole for guiding water droplets or the like that have entered between the inner peripheral surface and the outer peripheral wall of the annular projecting portion to the second drainage groove or the third drainage groove. Even if water drops enter from between the back of the housing and the wall packing, particularly water vapor enters from below, the water drops are provided with the annular drainage groove and the second drainage groove (third drainage groove). In this case, it is blocked by the third drainage groove) and does not easily reach the protruding portion (through hole) on the rear surface of the housing.

  Further, even when water droplets or the like enter from between the rear surface of the housing and the wall packing, the second water droplets or the like that have entered the wall packing between the outer peripheral wall of the protruding portion on the rear surface of the housing and the wall packing. Since the guide hole for guiding to the drainage groove or the third drainage groove is formed, the infiltrated water droplets or the like do not stay around the protruding portion but the second or third through the guide hole. Guided by the drainage groove, entry into the through hole in the rear surface of the housing is prevented.

At that time, by forming the entire length or a part of the third drainage groove on the rear surface of the housing in a substantially arc shape upward so as to be located at substantially the same distance from the outer peripheral wall of the annular projecting portion, If a wall packing with a guide hole having a substantially rectangular opening is used, when the wall packing is affixed to the rear surface of the housing, the affixing position of the wall packing is shifted and the guide hole is not in the vertical direction of the remote control. Even if it is inclined downward, the guide hole reaches the third drainage groove, so that drainage can be performed reliably.

  Further, by providing a drainage hole communicating with the annular drainage groove and penetrating through the surface of the housing below the annular drainage groove, the second or third drainage groove is guided. Water droplets and the like are discharged out of the remote control housing through this drain hole.

  In addition, if an inclined portion is formed at the upper end of the packing body of the wall packing, water droplets or the like that have entered from above and reached the upper end of the packing main body are either left or right side surfaces of the wall packing. Since it is guided to the side surface side, it is possible to suppress intrusion of water droplets or the like between the housing back surface and the wall packing.

  Further, the packing body is composed of a sponge-like pad, and an adhesive layer is formed on at least one of the front and back surfaces except for the vicinity of the upper end portion of the packing body, so that the wall packing is attached to the casing of the remote controller. When pasted on the back surface, no wrinkles are formed near the upper end where the pressure-sensitive adhesive layer is not formed, so that the waterproof effect can be further enhanced.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  An outer peripheral wall 4b of the pipe mounting portion 4 is provided so as to protrude from the housing back surface 2a. This is mainly for securing a mounting allowance for mounting the stay pipe, and for preventing water droplets or the like from entering the through-hole described later along the surface of the housing back surface 2a. In the form, the pipe mounting portion 4 is formed such that the contour of the outer peripheral wall 4b (in other words, the outer contour of the pipe mounting portion 4) is substantially circular.

  In the illustrated example, the outer contour of the pipe mounting portion 4 is formed in a substantially circular shape. However, for example, an elliptical shape or a shape close to a rectangle may be used. In short, it is only necessary that an annular protrusion is formed by the inner peripheral wall 4a for mounting the stay pipe and the outer peripheral wall 4b, and other shapes can be adopted as long as the above-described object can be achieved. is there.

  The grommet portion 5 is formed so as to protrude from the inner bottom portion 4c inside the pipe mounting portion 4, and an electrical wire insertion hole (through hole) 6 for inserting an electrical wire into the top surface 5a is a housing. 2 is opened through. Similarly, a vent hole (through hole) 7 for ventilation inside the housing 2 is also opened through the inside bottom portion 4 c so as to penetrate into the inside of the housing 2.

  A substantially rectangular annular drain groove 8 is formed around the outer peripheral edge 2b of the housing back surface 2a thus configured in accordance with the shape of the outer peripheral edge 2b (substantially rectangular in this embodiment). ing. Specifically, the drainage groove 8 is a drainage groove for draining water droplets or the like entering between the housing back surface 2a and the bathroom wall surface, and at least the outer peripheral wall 4b of the pipe mounting portion 4. Is formed so as to surround the outer peripheral wall 4b.

  More specifically, as shown in FIG. 3, the drainage groove 8 is configured by a groove having a substantially concave cross section with a width and depth of about several millimeters, and extends along the upper edge of the outer peripheral edge 2b of the housing back surface 2a. The upper edge groove 8a formed in this way, the left edge groove 8b and the right edge groove 8c formed on both the left and right edges, and the lower edge groove 8d formed along the lower edge communicate with each other. .

  A drainage hole 9 communicating with the lower edge groove 8d is provided below the lower edge groove 8d of the drainage groove 8. More specifically, the drain hole 9 is provided so as to penetrate the surface of the housing 2 as shown in FIG. In the remote controller 1 shown in the present embodiment, the opening on the front side of the housing of the drain hole 9 is formed so as to penetrate the hinge portion of the opening / closing lid A (see FIG. 2A) provided on the front of the housing. (See FIG. 2 (b)).

  That is, in the remote controller 1 shown in the present embodiment, the water droplets or the like that have flown into the drainage groove 8 flow into the lower edge groove 8d due to gravity, and further flow into the drainage hole 9 from the drainage hole 9 to the housing 2. It is configured to be discharged to the outside from the front side.

  And in the remote control 1 shown in this embodiment, it has a predetermined length in the left-right direction at a predetermined position inside the drainage groove 8 configured as described above, and a part thereof communicates with the drainage groove 8. A second drainage groove 10 is formed.

  The second drainage groove 10 mainly guides the waterdrops flowing down through the outer peripheral wall 4b of the pipe mounting portion 4 and the waterdrops flowing from the third drainage groove described later to the drainage groove 8, A through-hole (the above-described electrical wire insertion) in which the water droplets (specifically, water vapor) entering the drainage groove 8 (specifically, the lower edge groove 8d) from below is formed in the pipe mounting portion 4 It is formed for the purpose of preventing intrusion so as not to reach the hole 6 and the vent hole 7), and as shown in FIG. 1, below the pipe mounting portion 4 and inside the lower edge groove 8 d ( (Upward) includes a horizontal groove portion 10a formed in parallel with the lower edge groove 8d, and a guide groove portion 10b extending downward while communicating with the horizontal groove portion 10a and communicating with the lower edge groove 8d. .

  Specifically, the second drainage groove 10 is formed in a predetermined position on the rear surface 2a of the housing in the same manner as the drainage groove 8 described above, with a groove having a substantially concave shape with a width and depth of about several millimeters. (See FIG. 3), the horizontal groove portion 10a is located below the pipe mounting portion 4, and the length in the left-right direction is longer than the diameter (lateral width) of the pipe mounting portion 4. Is set to Here, the length in the left-right direction is set in this way because water droplets or the like that flow down along the outer peripheral wall 4b of the pipe mounting portion 4 easily flow into the horizontal groove portion 10a, and water vapor enters from below. This is to increase the prevention effect.

  In the illustrated example, the horizontal groove portion 10 is formed substantially horizontally in parallel with the lower edge groove 8d of the drainage groove 8. However, water droplets or the like that flow into the horizontal groove portion 10a flow into the guide groove portion 10b. It is also possible to form it with a downward slope toward the guide groove portion 10b so as to facilitate this.

  Further, the guide groove 10b is provided to guide water droplets or the like flowing into the horizontal groove 10a to the lower edge groove 8d of the drain groove 8, so that it is formed at both ends of the horizontal groove 10a as shown in the figure. For example, the horizontal groove 10a may be provided at the center. In short, the position, shape, number, and the like of the guide groove 10b can be appropriately changed in design as long as the above-described object can be achieved.

  Further, in the present embodiment, in addition to the second drainage groove 10, a third drainage groove 11 is formed between the pipe mounting portion 4 and the second drainage groove 10.

  The third drainage groove 11 is formed mainly for guiding water drops or the like flowing down through a guide hole 103 of the wall packing 100 described later to the second drainage groove 10 or the drainage groove 8. A water droplet or the like having a predetermined length in the left-right direction at a predetermined position inside the drainage groove 8 and below the pipe mounting portion 4 flows into the second drainage groove 10. In order to facilitate, it is configured to have an inclined portion inclined downward toward the second drainage groove 10 (or the drainage groove 8).

  Specifically, the third drainage groove 11 has a cross section of about several millimeters in width and depth at a predetermined position on the rear surface 2a of the housing, like the drainage groove 8 and the second drainage groove 10. It is configured by forming a concave groove (see FIG. 3). In the present embodiment, as shown in FIG. The lowermost part of the arc portion is formed so as to communicate with the second drainage groove 10.

  That is, the third drainage groove 11 is set so that each part of the groove is located at substantially the same distance from the outer peripheral wall 4b of the pipe mounting part 4 over the entire length thereof. Here, the third drainage groove 11 is formed in this way even when the wall packing 100 is obliquely bonded in relation to a guide hole 103 of the wall packing 100 described later (see FIG. 6). This is because water droplets or the like guided by the guide hole 103 flow into the third drainage groove 11.

  In the illustrated example, the case where the third drainage groove 11 is set to be substantially equidistant from the outer peripheral wall 4b of the pipe mounting portion 4 over the entire length of the third drainage groove 11 is shown. For example, a part of the third drainage groove 11 may be formed in an arc shape. In the illustrated example, a protrusion 12 is formed at a portion where the third drainage groove 11 and the second drainage groove 10 communicate with each other. However, when the communication portion becomes wider, the protrusion 12 has a water vapor from below. This is provided to prevent the intrusion of the material. Therefore, when the communication portion is narrow, such a protrusion 12 does not need to be provided. On the contrary, when the communication portion is wide, more protrusions 12 can be provided.

  In FIG. 1, reference numeral 13 denotes a support portion for supporting the housing rear surface 2 a by floating about several millimeters from the bathroom wall surface when the remote controller 1 is attached to the bathroom wall surface. Reference numeral 14 denotes a pasting position display section formed on the back surface 2a of the housing in order to indicate a pasting position of a wall packing 100 described later. In this embodiment, the pasting position display section 14 is a wall packing. 100 proper sticking positions are displayed by the outline of the wall packing 100. Further, a reference numeral 15 denotes a display unit for marking or the like formed to indicate a column for marking the model number or the like of the remote controller 1.

  Next, the wall packing according to the present invention will be described with reference to FIGS. FIG. 4 is an explanatory view showing an example of the wall packing according to the present invention. FIG. 4 (a) shows a front view of the wall packing, and FIG. 4 (b) shows a bottom view. FIG. 5 is an explanatory diagram showing a state in which the wall packing is properly affixed to the affixing position on the housing back surface 2 a of the remote controller 1. FIG. 6 is an explanatory diagram showing an example of a state in which the wall packing is not properly attached to the attachment position on the housing back surface 2 a of the remote controller 1.

  The wall packing 100 is a packing that is interposed between the housing back surface 2a of the remote control 1 and the bathroom wall surface when the remote control 1 is attached to the bathroom wall surface, and is a flat plate having a thickness of about several millimeters. It is formed with a member.

  Specifically, in this embodiment, the wall packing 100 is configured by a flat sponge-like member, and as shown in FIG. 4A, the upper end 101a is formed in a substantially rectangular shape having an arc shape. A main hole 102 having an opening capable of fitting the outer peripheral wall 4b of the pipe mounting portion 4 of the remote controller 1 at a predetermined position of the packing body 101, and a guide hole having a substantially rectangular opening shape communicating with the main hole 102. And 103.

  Here, the upper end portion 101a of the packing body 101 is formed in an arc shape so that when the wall packing 100 is interposed between the housing rear surface 2a of the remote controller 1 and the bathroom wall surface, the upper end portion 101a penetrates from above. By causing the water droplets or the like to flow down to the left and right of the packing by the arc-shaped inclined portion formed on the upper end portion 101a, the water droplets or the like are added to the pipe mounting portion 4 (specifically, the through holes 6 and 7). This is because it is difficult to penetrate. Therefore, the shape of the upper end portion 101a of the packing body 101 is such that water droplets or the like that enter from above and reach the upper end of the packing body 101 are guided to the left and right side surfaces or one of the side surfaces of the packing body 101. The design can be changed as appropriate as long as the shape is appropriate.

  The main hole 102 only needs to have an opening into which the outer peripheral wall 4b of the pipe mounting portion 4 can be fitted. More preferably, the packing body 101 is attached to the housing rear surface 2a of the remote controller 1. When mounted, the main hole is adapted to match the contour of the outer peripheral wall 4b so that a gap generated between the outer peripheral wall 4b of the pipe mounting portion 4 and the inner peripheral surface 102a of the main hole 102 becomes as small as possible. The shape of 102 is set.

  Further, the guide hole 103 is formed so that the guide hole 103 communicates below the main hole 102 when the packing main body 101 is attached to an appropriate application position on the housing rear surface 2a of the remote controller 1. Yes. That is, when water droplets or the like enter the guide hole 103 from the upper end portion 101a of the packing body 101 between the packing and the housing back surface 2a, the water droplets or the like that enter the outer peripheral wall of the pipe mounting portion 4 4b and guided to the third drainage groove 11 or the second drainage groove 10 without accumulating in a gap formed between the inner peripheral surface 102a of the main hole 102, In the present embodiment, the length dimension (vertical dimension in the figure) of the guide hole 103 is set to a length that allows the lower end portion 103a to reach the second guide groove 10 as shown in FIG. Yes.

  As described above, since the third drainage groove 11 communicates with the second drainage groove 10, the guide hole 103 has a length dimension that reaches at least the third drainage groove 11. As long as it has.

  And the adhesive layer for adhere | attaching this packing main body 101 to the housing | casing back surface 2a of the remote control 1 and a bathroom wall surface is formed in the front and back of this packing main body 101. As shown in FIG. Specifically, in the present embodiment, the pressure-sensitive adhesive layer is formed in a portion indicated by hatching in FIG. 4, that is, in other portions except for the vicinity of the upper end portion 101 a of the packing body 101.

  Here, the pressure-sensitive adhesive layer is formed only on the portion other than the vicinity of the upper end portion 101a of the packing body 101. When the packing body 101 is bonded to the housing back surface 2a, a wrinkle is formed near the upper end portion 101a. This is to prevent the occurrence. That is, as described above, if an adhesive layer is formed on the entire surface of a packing made of a sponge-like soft material, wrinkles may occur when the packing body 101 is affixed to the housing back surface 2a. In the embodiment, by not forming an adhesive layer in the vicinity of the upper end portion 101a, wrinkles are prevented from occurring in the vicinity of the upper end portion 101a, thereby improving the waterproof effect on the upper end side of the wall packing 100. .

  In addition, since the occurrence of such wrinkles is finally prevented from intruding water droplets or the like from the upper end side of the packing body 101 into the through holes 6 and 7 provided in the pipe mounting portion 4. The part (non-adhesive part) where the adhesive layer is not formed is set so as to include at least the range from the upper end part 101 a of the packing body 101 to the upper end part of the main hole 102.

  The wall packing 100 configured as described above is, as shown in FIG. 5, firstly attached on the back surface 2 a of the casing 2 of the remote controller 1 when the remote controller 1 is mounted on the bathroom wall surface. Affixed to the contours shown. And by attaching the remote control 1 to a bathroom wall surface, it interposes between the housing | casing back surface 2a and a bathroom wall surface, and functions to seal between both by elastically deforming between both.

  Thus, the remote controller attached to the bathroom wall surface using the remote controller 1 and the wall packing 100 according to the present invention does not have an adhesive layer formed near the upper end 101a of the wall packing 100. The vicinity of the upper end portion 101a is closely adhered, and the upper end portion 101a is formed with an inclined portion. Therefore, even if the caulking around the remote controller 1 is broken and water drops enter from above, Is prevented from reaching the pipe mounting portion 4 by the wall packing 100.

  Even if water droplets or the like enter from the upper end portion 101a side of the packing body 101, the guide holes 103 communicating with the main hole 102 of the wall packing 100 are formed. The drainage groove flows down to the third drainage groove 11 and the second drainage groove 10 through the guide hole 103 without accumulating in a gap formed between the outer peripheral wall 4b of the main hole 102 and the inner peripheral surface 102a of the main hole 102. 8. It is discharged to the outside through the drain hole 9. Therefore, even if a water droplet or the like enters from above the wall packing 100, the water droplet or the like does not enter the inside of the housing 2 from the through holes 6 and 7 formed in the pipe mounting portion 4.

  In the remote controller 1 shown in the present embodiment, the third drainage groove 11 is formed so as to be located at substantially the same distance from the outer peripheral wall 4b of the pipe mounting portion 4 over its entire length. Even when the packing 100 is attached obliquely as shown in FIG. 6, the water droplets or the like that have entered from above are guided to the third drainage groove 11 through the guide hole 103, and thus the above-described effects are obtained. Not damaged.

  Moreover, the wall packing 100 prevents water droplets or the like (mainly water vapor) that breaks down the caulking around the remote controller 1 from the lower side and enters the gap between the wall packings 100 (for example, during bonding). Even if it has entered from the above-mentioned drainage grooves 10 and 11, the second drainage groove 10 and the third drainage groove 11 prevent upward intrusion. It is discharged outside. Therefore, even if a water droplet or the like enters from below the wall packing 100, the water droplet or the like does not reach the pipe mounting portion 4 and does not enter the inside of the housing 2 from the through holes 6 and 7. .
