Description

  The present invention relates to an electric device mounting base member used for mounting an electric device such as a remote controller of a water heater or a thin television on a desired wall portion such as a bathroom, and an electric device mounting structure including the same.

  As a method of attaching an electric device such as a remote controller of a water heater to a wall portion of a bathroom, instead of directly attaching the electric device to the wall portion, a base member is used, and the electric device is attached to the wall portion via the base member. There is a method of indirectly attaching to (see, for example, Patent Document 1). When the base member is used, it is possible to attach a plurality of electric devices together on the front surface portion. However, when mounting electrical equipment using the base member, while protecting the wiring of the electrical equipment attached to the front side of the base member appropriately using a stay pipe, the back side of the base member It is often difficult to pull out.

  Therefore, the inventor of the present invention has newly conceived of providing a wiring hole in the base member for passing the wiring of the electric device from the front side to the back side of the base member. However, if the wiring is simply passed through the back side of the base member, when water enters between the base member and the wall of the bathroom, the wiring may get wet and the electrical system may be adversely affected. There is. As a means for preventing this, for example, a means for filling the caulking agent between the base member and the wall can be considered. When deterioration occurs, water may enter between the electrical equipment and the wall, and the electrical wiring may get wet, so there is room for improvement in protecting the electrical system.

JP 2004-53221 A

  The present invention has been conceived under the circumstances as described above, facilitates the wiring of the wiring of the electric device, and between the wall portion to be attached to the electric device and the base member. An electric equipment mounting base member capable of appropriately preventing electrical wiring from getting wet with water even when water enters, and an electrical equipment mounting structure including the same The challenge is to provide

  In order to solve the above problems, the present invention takes the following technical means.

The electric device mounting base member provided by the first aspect of the present invention can be mounted on the front surface side of the electric device, and can be mounted on the wall portion with the back surface facing a desired wall portion. A base member for mounting electrical equipment, comprising a base member main body, the wiring hole being provided in the base member main body and for passing the wiring of the electrical equipment to the back side of the base member main body It is possible to cover the upper part of the wiring of the electric device, to be located above the wiring hole, to protrude from the base member main body part toward the back, and to receive the water that has dropped from above. And at least a part of the flange portion is inclined in the vertical height direction, and the water received by the flange portion causes the wiring hole and the wiring to be It is characterized in that it is configured to be capable flow down downwards after being guided to a position offset from a position directly above.

According to such a configuration, the following effects can be obtained.
1stly, when attaching an electric equipment to the front side of a base member main-body part, it should just set so that the wiring of an electric device may pass through the hole for wiring as it is, and may be located in the back side of a base member main-body part. Therefore, the structure for drawing the wiring of the electric device to the back side of the base member main body is simple and the wiring can be easily handled.
Second, even if there is a gap between the upper part of the base member main body and the wall part to which the electrical device is to be attached, even if water enters from this gap, It can be led down to the position offset from the position directly above the wiring hole and the wiring of the electric equipment, and can flow down. Therefore, it is possible to appropriately prevent the wiring from getting wet with water and to prevent the water from entering the wiring hole, thereby enhancing the protection of the electric system.

  In the present invention, preferably, a receiving portion provided at a lower portion of the base member main body portion and capable of receiving the liquid falling from the collar portion, and the liquid received by the receiving portion as the base member main body. And a drainage hole that can flow down to the lower side of the base member main body after passing through the front side of the part.

  According to such a configuration, it is possible to appropriately discharge the water that has flowed down from the flange portion to the outside of the base member, so that a large amount of water does not accumulate between the lower portion of the base member main body portion and the wall portion. . In addition, if the water that has passed through the drainage holes flows down from the front side of the base member main body, the surface of the wall is less than when the water flows down along the surface of the wall. The effect of making it less likely to cause water stains can also be expected.

  In the present invention, preferably, the upper surface of the flange portion is inclined so as to decrease in height as it proceeds from a substantially central portion in the left-right width direction to both end portions, and the receiving portion is at both ends of the flange portion. The drainage holes are provided with a pair of holes located below or near the lower ends of both ends of the flange. Yes.

  According to such a configuration, the water received by the eaves portion is rapidly advanced to the end portion of the eaves portion and dropped downward, and at least one of the pair of drain holes is passed through the dropped water. It is possible to quickly discharge to the outside using this. Therefore, smoothing of drainage can be promoted and the time during which water stays between the base member main body portion and the wall portion can be shortened.

  In the present invention, it is preferable to further include a stay pipe connecting portion that is provided on the back side of the base member main body portion and connects the base member main body portion to a stay pipe. Is configured such that when the stay pipe is connected, a gap is formed between the tip of the stay pipe and the back surface of the base member main body, and an opening is formed around the gap. Of the wiring of the electrical equipment, a portion that is passed through the wiring hole and disposed on the back side of the base member main body enters the gap through the opening and enters the interior of the stay pipe. It can be passed through. Here, the stay pipe is a pipe that is directly or indirectly connected to an electric device to be attached to a wall and can directly or indirectly support the electric device, and is a wiring of the electric device. Can be passed inside.

  According to such a configuration, the base member main body and the stay pipe can be appropriately connected, and the wiring of the electric device arranged on the back side of the base member main body can be connected to the stay pipe. It is also possible to pass inside properly.

  The electric equipment mounting structure provided by the second aspect of the present invention includes a base member attached to a desired wall portion and one or more electric equipments attached to the front side of the base member. In the electric equipment mounting structure, the base member for electric equipment mounting provided by the first aspect of the present invention is used as the base member.

  According to such a configuration, an effect similar to that described for the electric device mounting base member provided by the first aspect of the present invention can be obtained.

  Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

It is a perspective view which shows an example of the attachment structure of the electric equipment which concerns on this invention. It is II-II sectional drawing of FIG. It is a disassembled perspective view of the attachment structure of the electric equipment shown in FIG. FIG. 2 is an exploded cross-sectional view of a main part of the electric device mounting structure shown in FIG. 1. It is a back perspective view of the base member used for the attachment structure of the electric equipment shown in FIG.

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

  1 to 5 show an embodiment of an electric equipment mounting structure to which the present invention is applied. As shown well in FIG. 1, the electrical equipment mounting structure S of the present embodiment uses a base member B and a remote control of a TV unit 6A and a water heater (not shown) on a wall portion 7 standing in a bathroom. 6B is attached.

  2 to 4, the television unit 6A includes a television body 60A and a cover body 61A attached to the television body 60A from the front side. Similarly, the remote controller 6B includes a remote controller main body 60B and a cover body 61B attached to the remote controller main body 60B from the front side. As the television unit 6A and the remote controller 6B, known ones can be used as appropriate, and the description thereof is omitted.

  The base member B corresponds to an example of an electric equipment mounting base member to which the present invention is applied. The base member B is made of a synthetic resin which is relatively hard as a whole, and has a substantially rectangular base member main body 1 in front view, It has the connecting part 2 for stay pipes provided. As shown in FIG. 3, the base member main body 1 has a plate-like portion 10 having a flat front surface, and two wiring holes 11 are formed vertically on the plate-like portion 10. It is provided at intervals. These wiring holes 11 are for passing the wirings 62A and 62B of the TV unit 6A and the remote control 6B to the back side of the base member main body 1.

A plurality of screw holes 12 are provided on the peripheral edge of the base member main body 1. The television body 60A and the remote control body 60B can be fixed to the front side of the base member body 1 by using the screw body 99 screwed into the screw hole 12. The cover bodies 61A and 61B are attached to the television body 60A and the remote controller body 60B after they are attached to the base member B. As shown in FIG. 2 and FIG. 4, a seal member 63 made of a loop-like elastic member that surrounds the bases of the wirings 62A and 62B is attached to the back surfaces of the TV main body 60A and the remote control main body 60B. Yes. When the seal member 63 comes into contact with the plate-like portion 10 of the base member B, a water-stop seal of this portion is achieved. As a result, even if water enters between the TV main body 60A and the base member main body 1 or between the remote control main body 60B and the base member main body 1, this water is the base of the wirings 62A and 62B. Proceeding toward is properly prevented.

  The stay pipe connecting portion 2 is configured by integrally forming a pair of projecting portions 20 on the back surface portion of the base member main body portion 1. As clearly shown in FIG. 5, the pair of projections 20 are opposed to each other with a pair of slit-like gaps 21 therebetween, and the cylindrical projection is divided into left and right parts. It is the same composition as. A screw portion 22 for screwing a screw portion 50 on the outer periphery of the distal end portion of the stay pipe 5 is provided on the inner peripheral surfaces of the pair of protrusions 20. However, the screw portion 22 is provided only in the range of the middle height from the tip side of each projection portion 20, and is not provided in the vicinity of the base portion of each projection portion 20. As a result, as shown in FIG. 2, when the screw portion 50 of the stay pipe 5 is screwed into the screw portion 22, the distal end portion of the stay pipe 5 does not advance to the proximal end of each projection portion 20. A gap 30 is formed between the tip of the stay pipe 5 and the back surface of the base member main body 1. The gap 30 is a portion that allows the wires 62A and 62B to enter the tip opening without closing the tip opening of the stay pipe 5. As a means for forming the gap 30, instead of providing the screw portion 22 to a midway height, for example, when the tip of the stay pipe 5 has advanced to a midway height of each projection 20, the stay pipe 5 A means for providing a stopper (not shown) in contact with the base member main body 1 may be employed.

  As shown in FIG. 2, when the stay pipe 5 is connected to the stay pipe connecting portion 2, two openings 21 a that allow the gap 30 to communicate with the external space are formed. These openings 21a are a part of the two gaps 21 shown in FIG. 5 (a part of the gap 21 that is not closed by the stay pipe 5). The wirings 62A and 62B pass through the two wiring holes 11 and are arranged on the back side of the base member main body 1. The wirings 62A and 62B pass through the opening 21a and enter the gap 30. After entering, the state is set to be passed through the stay pipe 5. In the assembly procedure of the electrical equipment mounting structure S, it is not necessary to pass the wires 62A and 62B through the stay pipe 5 after the stay pipe 5 is connected to the stay pipe connecting portion 2. It goes without saying that the stay pipe 5 may be connected to the stay pipe connecting portion 2 after the wires 62A and 62B have been passed through the stay pipe 5 first. The stay pipe 5 is inserted and fixed in a hole 70 provided in the wall 7 of the bathroom. The wires 62A and 62B pass through the stay pipe 5 and are drawn out of the bathroom.

  As clearly shown in FIG. 5, on the back side of the base member main body 1, a frame-shaped convex portion 13 having a rectangular loop-shaped sealing member 80 attached thereto, reinforcing ribs 14 and 15, and ribs 15. Are provided with a plurality of notch recesses 16 and a flange 4 serving also as a reinforcing rib.

  The frame-shaped convex part 13 protrudes toward the back from the outer peripheral edge part of the plate-shaped part 10 so that it may appear well in FIG. 2 and FIG. When the base member B is attached to the wall portion 7, the seal member 80 is sandwiched between the frame-shaped convex portion 13 and the wall portion 7, and a water sealing is achieved. This suppresses water from entering between the wall portion 7 and the base member B. The frame-shaped convex portion 13 and the seal member 80 are provided with screw body insertion holes 19 for enabling the base member B to be screwed to the wall portion 7. If such a screwing means is provided, the mounting strength of the base member B can be made higher than when the base member B is fixed using only the stay pipe 5, and the stay pipe 5 is not used. Mounting is also possible, providing excellent flexibility.

The reinforcing rib 14 is located between the pair of protrusions 20 and has a shape extending in a direction in which the pair of protrusions 20 face each other. The stay pipe connecting portion 2 and its peripheral portion may receive a relatively large force from the stay pipe 5, but the presence of the ribs 14 can efficiently reinforce those portions.

  As the ribs 15, there are a plurality of vertical ribs extending in the vertical direction and a plurality of horizontal ribs extending in the left and right substantially horizontal directions, and these are connected to cross each other. According to such a structure, the wide area of the base member main-body part 1 can be reinforced efficiently. The plurality of ribs 15 include two ribs 15 a located between the wiring hole 11 and the stay pipe connecting portion 2, and a notch recess 16 is provided in these ribs 15 a. As shown in FIG. 2, the notch recess 16 is a portion for allowing a part of the wirings 62 </ b> A and 62 </ b> B to enter and be locked. This makes it possible to position the wirings 62A and 62B when the mounting structure S is assembled.

  Even if water enters between the upper part of the base member main body 1 and the wall 7, the flange 4 is a part for appropriately dealing with this. The flange 4 is located near the upper portion of the base member main body 1 so as to be positioned above the two wiring holes 11 and the stay pipe connecting portion 2, and is similar to the reinforcing ribs 14 and 15. The rib shape protrudes toward the back of the base member main body 1. As shown in FIG. 2, the height H <b> 1 of the flange portion 4 is preferably a height at which the tip of the flange portion 4 comes into contact with or approaches the wall portion 7. When water enters between the wall portion 7, the water can be received by the upper surface 40. Although the height H1 of the collar part 4 is so preferable that it is so high that the clearance gap between the collar part 4 and the wall part 7 becomes small, the specific value is not ask | required. However, it is desirable that the height H1 of the collar portion 4 is higher than at least the height H2 of the gap 30. If H1> H2, the upper part of the wirings 62A and 62B that are not inserted into the stay pipe 5 is appropriately covered with the flange part 4, and water can be prevented from flowing directly to the part. It is.

  As shown in FIG. 5, the collar portion 4 is inclined in a substantially square shape so that the substantially central portion 4a in the left-right width direction is the highest and the height gradually decreases as it goes to the width direction both end portions 4b. It has a form. Thereby, the water received by the upper surface 40 of the collar part 4 flows toward both or one side of the both ends 4b, as shown by the arrow N1. Both end portions 4b of the flange portion 4 are positioned on the outer side in the left-right width direction of the base member B with respect to the plurality of reinforcing ribs 15 (of course, left and right from the positions directly above the wiring holes 11 and the wirings 62A and 62B). The water reaching the both ends 4b passes through the outer side of the outermost vertical ribs 15b and is located closer to the lower part of the base member main body 1 as indicated by the arrow N2. It falls on the receiving part 17.

  The receiving portion 17 is constituted by a part of the frame-like convex portion 13 and is connected to intersect with the lower edge portion of the plate-like portion 10. A pair of drainage holes 18 are provided at both ends in the width direction of the lower edge of the plate-like portion 10. Preferably, similarly to the flange portion 4, the receiving portion 17 is inclined so that the height gradually decreases as it proceeds from the substantially central portion in the left-right width direction to both end portions, and is received by the receiving portion 17. Water is configured to smoothly flow into the drain hole 18. As shown by an arrow N3 in FIG. 2, the water received by the receiving portion 17 passes through the drainage hole 18 and flows to the front side of the base member main body portion 1, and then below the base member main body portion 1. It is supposed to flow down. Preferably, the upper surface of the receiving portion 17 is inclined in a front-down manner, so that the water flows into the hole portion 18 more smoothly. As shown in FIG. 2, the remote controller 6 </ b> B is disposed so as to cover the front surface of the hole 18 while being provided so as not to close the hole 18. In this way, if the front surface of the hole 18 is covered by the remote controller 6B, the risk of water entering the hole 18 from the front surface can be eliminated or reduced.

  Next, the operation of the electrical equipment mounting structure S described above will be described.

First, the wires 62A and 62B of the TV unit 6A and the remote controller 6B of the water heater are passed through the two wiring holes 11 to the back side of the base member B and enter the gap 30 through the opening 21a, so that the stay pipe 5 can be set appropriately. The TV unit 6A and the remote control 6B may be attached by contacting or approaching the front surface of the base member B so that the bases of the wirings 62A and 62B face the wiring holes 11. By changing the position of the wiring hole 11, the arrangement of the TV unit 6A and the remote controller 6B can be freely changed. In addition, it is not necessary to provide a space for guiding the wires 62A and 62B into the stay pipe 5 between the TV unit 6A or the remote controller 6B and the base member B. Therefore, it is preferable to avoid the television unit 6A and the remote controller 6B being provided in a large and bulky state on the front side of the base member B.

  On the other hand, although the stay pipe connecting portion 2 is provided on the back side of the base member B, the stay pipe connecting portion 2 itself is configured by using a pair of protrusions 20, The height of the reinforcing rib 15 can be a small size equal to or lower than the height of the reinforcing rib 15 or the like. Therefore, although the structure on the back side of the base member B is somewhat complicated, the entire electrical equipment mounting structure S is based on the fact that it is not necessary to provide a space for arranging the wirings 62A and 62B on the front side of the base member B. It is possible to reduce the size.

  The operation of passing the wires 62A and 62B through the stay pipe 5 can be performed collectively on the back side of the base member B. Therefore, the work becomes easy. In particular, in the present embodiment, the wirings 62A and 62B are locked to the notch recess 16, so that the wirings 62A and 62B can be prevented from inadvertently moving when the wirings 62A and 62B are routed. , The operation is made easier. The notch recess 16 is rational because it is provided using the reinforcing rib 15a of the base member B. Further, since the base member B is also provided with the ribs 14 and the flange portion 4 that exhibits a reinforcing function, it is possible to ensure sufficient strength while reducing the thickness of each part of the base member B. .

  In the present embodiment, the water stop seal using the seal members 63 and 80 prevents water from entering a predetermined portion, thereby appropriately protecting the electric system. When the seal member 80 is deteriorated or the surface of the wall portion 7 is tiled and the joint portion of the tile has a deep concave shape, the space between the upper portion of the base member B and the wall portion 7 However, as will be described below, such a situation can be appropriately dealt with. That is, as indicated by arrows N1 to N3 in FIGS. 5 and 2, the water described above is received by the flange 4 and then guided toward the end 4b and flows down from the end 4b, and thereafter Is received by the receiving part 17, passes through the drain hole 18, and is discharged below the base member B. Therefore, the wirings 62A and 62B are more thoroughly prevented from getting wet. Moreover, it is also avoided appropriately that much water accumulates in the lower part of the base member B. Furthermore, if water is dropped and discharged from the front surface side of the base member B, unlike the case where water is discharged along the surface of the wall portion 7, the effect of making it difficult for water stains to occur on the surface of the wall portion 7 is also achieved. I can expect.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of each part of the electric device mounting base member and the electric device mounting structure according to the present invention can be varied in design in various ways.

The heel portion according to the present invention is only required to be inclined at least partially so that it can flow downward after guiding the received water from the position directly above the wiring hole and the wiring of the electrical equipment. It is possible to adopt a form different from the substantially square shape of the embodiment. For example, it is also possible to adopt a form that is inclined in only one direction from one end part in the left-right width direction to the other end part, or a form in which the inclined part is curved. In addition, the water that has flowed down from the flange portion is provided on the back side of the base member main body (for example, on the back surface of the base member main body or on this back surface instead of being discharged to the outside from the front side of the base member main body. The base member main body is configured to be discharged to the outside from between the sealing member and the wall portion, or a hole penetrating in the vertical direction is provided in the lower portion of the base member main body portion. It can also be set as the structure discharged | emitted below from the lower part (hole part) of a part.

  The present invention can be applied even when the base member is not connected to the stay pipe. More specifically, even when the base member is screwed to the wall without connecting the stay pipe to the base member, even when the wiring of the electric device is directly inserted into the hole of the wall. The present invention is applicable, and it is possible to appropriately prevent the wiring from being splashed by the presence of the collar portion.

  The base member of the above embodiment is suitable for attaching a plurality of electric devices to the wall portion together, but the present invention is not limited to this, and is also applied to a case where only one electric device is attached to the wall portion, for example. It is possible. As the electric device, various devices other than the television unit and the remote controller of the water heater can be applied. Needless to say, the wall part to which the electric device is attached is not limited to the wall part of the bathroom, but can be a wall part of a kitchen or other various rooms or places.
