Description

  The present invention relates to a bracket used for installing a desired installation target device in a bathroom, and a hot water supply system including the bracket.

  In recent years, when replacing a hot water supply device in a general household, the non-latent heat recovery type is often changed to a latent heat recovery type. In the latent heat recovery type hot water supply apparatus, since a large amount of drain (condensate) is generated due to the latent heat recovery, construction for drainage treatment of the drain is necessary. However, for example, in a housing complex, there is a case where a drain outlet is not provided in the pipe space where the hot water supply device is installed.

  As a hot water supply system capable of coping with such a case, for example, there is one described in Patent Document 1. In the hot water supply system described in this document, the drain generated in the hot water supply device is guided into the bathroom and poured into the drain pan of the bathroom. As means for concretely realizing such a configuration, a three-way valve is connected by piping to a circulation adapter of the bathtub. This three-way valve is controlled so that when the drain is sent from the hot water supply device, the drain is poured into the drain pan, and when hot water is sent from the hot water supply device, the hot water flows to the circulation adapter of the bathtub. The According to such a configuration, even when the drain outlet dedicated to the drain is not provided at the location where the hot water supply device is installed, the drain can be appropriately disposed of using the drain pan of the bathroom. Is possible.

  However, when a hot water supply system as described above is constructed in accordance with replacement of a hot water supply device, it is necessary to install a three-way valve in the bathroom. This three-way valve is, for example, an electromagnetic system that can be operated remotely, and because it has a certain size and weight, it is not easy to assemble directly into the circulation adapter of the bathtub, and the circulation adapter is not compatible with that. Most of the cases. Therefore, it is conceivable to install the three-way valve at a position away from the circulation adapter and to pipe these, but in the past, a bracket for easily installing the above-described devices such as the three-way valve in the bathroom is proposed. The fact is not being done. The above-described three-way valve is preferably installed, for example, in a region between a bathtub and a bathroom wall, but conventionally, a device such as a three-way valve cannot be easily installed in such a narrow region. The installation work was difficult.

The drain drainage unit 5 corresponds to an example of an installation target device referred to in the present invention, and includes a three-way valve 50 described later. In FIG. 1 and FIG. 2, for ease of understanding, the drain drainage unit 5 is shown not attached to the bracket B. However, the drain drainage unit 5 is attached to the bracket B as described later. The bracket B is attached to the bathroom penetrating tool 2.

  The hot water supply apparatus 1 is configured as a latent heat recovery type gas hot water supply apparatus having a general hot water supply function and a bath hot water supply function. The hot water supply device 1 has the same basic configuration as that conventionally known, and heat exchange for recovering sensible heat and latent heat from the combustion gas generated by the gas burners 10a and 10b, the fan 11, and the gas burners 10a and 10b. 12a, 12b, a neutralizer 13 that neutralizes the strongly acidic drain that is generated along with the recovery of latent heat and is sent through the flow path 37, and for storing the drain that has been neutralized. A drain tank 14 is provided. In the general hot water supply operation of the hot water supply device 1, water supplied to the water inlet 30 a is supplied to the heat exchanger 12 a through the pipe part 30 and heated, and hot water generated by this heating passes through the pipe parts 31 and 32. To the currant 33 and the like.

  The hot water flow paths Ra and Rb connecting the hot water supply device 1 and the circulation adapter 40 of the bathtub 4 have the following configuration. That is, in the hot water flow paths Ra and Rb, the other ends of the external pipes 35a and 35b whose one ends are connected to the hot water supply apparatus 1 are connected to the bathroom via the pair of pipe portions 20 provided in the bathroom penetrating tool 2. It is connected to the inner piping members 36a, 36b. In addition, in FIG. 1, the code | symbol 43 shows the outer wall of a house and the code | symbol 42 has shown the wall part of the bathroom. One end of the piping member 36 b is connected to a connection port that communicates with the suction port 40 b of the circulation adapter 40. One end of the piping member 36 a is connected to the drain drainage unit 5 and indirectly connected to a connection port communicating with the discharge port 40 a of the circulation adapter 40 via the drain drainage unit 5. As shown in FIG. 3, the drain drainage unit 5 has a structure in which a three-way valve 50 having ports P <b> 1 to P <b> 3 is housed and protected in a case 51 made of resin or the like. The three-way valve 50 is an electromagnetic valve, and an electric wiring 52 for power supply and signal is drawn outside the case 51.

In FIG. 1, the hot water distribution path at the time of bathing operation is indicated by a bold line. During the bath chasing operation, the circulation pump P provided in the internal pipe 38b of the hot water supply device 1 is driven so that hot water in the bathtub 4 is pumped up to the hot water flow path Rb and the internal pipe 38b, and then the heat exchanger. 12b. The hot water heated by the heat exchanger 12b is returned to the bathtub 4 through the internal pipe 38a and the hot water channel Ra. At that time, the drain drainage unit 5 can communicate hot water from the drain drainage unit 5 to the circulation adapter 40 because the ports P1 and P2 communicate with each other. Port P3 is in a closed state. The three-way valve V2 positioned at the connection between the drain storage tank 14 and the internal pipe 38b is closed on the tank 14 side to prevent the drain from flowing from the tank 14 into the internal pipe 38b. In addition, the hot water filling operation to the bathtub 4 is performed by opening the on-off valve V1 provided in the hot water supply device 1 and supplying hot water from the pipe portions 31 and 34 to the internal pipe 38b to flow into the flow paths Ra and Rb.

During this operation, the three-way valve V2 is open on the drain tank 14 side, and when the circulation pump P is driven, the drain in the tank 14 passes through the internal pipes 38b and 38a and the hot water flow channel Ra. It is sent to the drain drainage unit 5. In the drain drainage unit 5, the ports P1 and P2 are not connected, and the port P3 is open. For this reason, the drain is discharged from the port P3 to the drain pan 41 of the bathroom. Since the drain drain unit 5 is actually supported by the bracket B and installed above the bathroom penetrating tool 2, a hose (not shown) is connected to the port P3, and through this hose. Drain discharge to the drain pan 41 is performed. In the hot water supply system S, after the drain discharge operation described above is completed, it is also possible to execute an operation of causing the previous drain circulation path to flow hot water and cleaning the path. However, the details are omitted.

  As shown in FIG. 3 and FIG. 4 (b), the bathroom penetrating tool 2 has a configuration in which a pair of tube parts 20 penetrates and is joined to a fixed plate 21. The pair of tube parts 20 are arranged at intervals in the horizontal direction (however, in FIG. 1 and FIG. 2, they are shown in a state where they are lined up and down for convenience), and are in a state of penetrating the wall part 42 of the bathroom. It is attached. The distal end portion of each tubular body portion 20 is located in the bathroom, but this portion is used for mounting the bracket B as described later. A nut 22 is screwed and attached to the distal end side of each tubular body portion 20, and this nut 22 is for fixing the bathroom penetrating tool 2 to the wall portion 42. By tightening the nut 22, the bathroom wall 42 is sandwiched between the nut 22 and the fixing plate 21, and the bathroom penetrating tool 2 is fixed.

As shown in FIG. 3 and FIG. 4A, the bracket B includes a bracket body 6 and a pair of engaging portions 7 provided to be connected to both lower ends of the bracket body 6. . These portions of the bracket B can be integrally formed by bending a single metal plate formed in a predetermined shape.
Each engaging portion 7 has engaging pieces 7A and 7B. The engagement piece 7A corresponds to an example of a first engagement piece referred to in the present invention, and the engagement piece 7B corresponds to an example of a second engagement piece referred to in the present invention.

The engaging piece 7 </ b> A can be engaged with the nut 22 of the bathroom penetrating tool 2. The engaging piece 7A has a substantially semicircular arc shape in which one end is integrally connected to the lower portion of the bracket body 6 and the front end is a free end. Is open. In a natural state where the engagement piece 7A is not elastically deformed, as shown in FIG. 4A, the center distance L1 between the pair of engagement pieces 7A (the distance between the centers of the arcs of the engagement pieces 7A). Is longer than the center-to-center distance L2 (arrangement pitch) of the pair of nuts 22. With such a configuration, as shown in FIGS. 5 and 6, the pair of engaging pieces 7 </ b> A are disposed between the pair of nuts 22 in an elastically deformed state, and the engaging pieces 7 </ b> A are disposed on the respective nuts 22. If they are externally fitted, the pair of engaging pieces 7A are brought into pressure contact with the outer surface portion of the nut 22 by the elastic restoring force, and are engaged and held. A bent portion 70a bent outward is continuously provided at the distal end portion of each engaging piece 7A. When performing an operation of deforming the engaging piece 7A, the bent portion 70a is used as a knob. can do.

  The engagement piece 7B is a part that plays a role of further stabilizing the state in which the engagement piece 7A is engaged with the nut 22. Similar to the engagement piece 7A, the engagement pieces 7B are provided in a pair of left and right in a state of protruding downward from the bracket main body 6, but are positioned forward of the engagement pieces 7A. Further, the engaging piece 7B has an arc shape shorter than the engaging piece 7A, has a downward opening shape, and can be elastically deformed in the vertical direction. Similar to the bent portion 70a of the engaging piece 7A, the engaging piece 7B is also provided with a bent portion 70b that can be used as a knob.

  The engaging piece 7B can be brought into pressure contact with the upper surface of the tubular body portion 20 of the bathroom penetrating tool 2 when the engaging piece 7A is engaged with the nut 22. In the present embodiment, since the piping members 36a and 36b are fitted and connected to the one end opening of the tubular body portion 20 and the upper surface of the tubular body portion 20 is exposed, the exposed upper surface of the engaging piece 7B is exposed. It can be made to contact. In the present embodiment, the pair of tube portions 20 and the nut 22 correspond to a fixing member as an engagement target of the bracket in the present invention. Unlike the present embodiment, when the pipe members 36a and 36b are externally connected to the pipe body portion 20 so that the upper surface of the pipe body portion 20 is not exposed, the engaging piece 7B is a pipe member. It will press-contact with the upper surface of 36a, 36b. In this case, the piping members 36a and 36b and the nut 22 correspond to a fixing member as an engagement target of the bracket B.

  The bracket body 6 is a part for attaching the drain drainage unit 5. In the present embodiment, the drain drainage unit 5 can be held by the bracket body 6 without using a means such as a screw stopper.

  More specifically, the bracket body 6 includes a connecting portion 63 that connects the pair of engaging portions 7, a flat plate-like back plate portion 60 that stands upward from the connecting portion 63, and the back plate portion 60. A horizontal plate-like support plate portion 61 formed on the front surface side and a pair of holding piece portions 62 protruding forward from the upper portion of the back plate portion 60 are provided. A bent piece 62a bent inward is formed at each tip of the pair of holding pieces 62. The support plate portion 61 can be formed integrally with the back plate portion 60 by processing a part of the back plate portion 60 into a flat, two-fold plate shape. As shown by the arrow N1 in FIG. 3, the pair of holding piece portions 62 can be elastically deformed (flexible deformation) in the direction in which they face each other, and the gap between the bent piece portions 62a and drain drainage is greatly increased. It is possible to make the drain drainage unit 5 enter between the pair of holding pieces 62 while avoiding interference with the unit 5. As a result, as shown in FIG. 7, the drain drainage unit 5 can be placed on the support plate portion 61. If an elastic restoring force is generated in the pair of holding pieces 62, the bent piece 62a is positioned on the front side of the drain drainage unit 5 and is locked to the front portion.

  As shown in FIG. 8, the bracket B can attach the drain drainage unit 5 in a direction different from that in FIG. 7. In FIG. 7, the ports P1 to P3 are located on the left side of the drain drainage unit 5 and the port P1 is facing left, whereas in FIG. 8, the ports P1 to P3 are located on the right and the port P1 is facing right. is there. The construction worker can appropriately select one of the orientations shown in FIGS. 7 and 8 in consideration of the piping connection workability to the ports P1 to P3.

  Next, the operation of the hot water supply system S described above will be described.

In order to install the drain drainage unit 5 in the bathroom, the bracket B is attached to the bathroom penetrating tool 2. The mounting of the bracket B is performed by inserting the pair of engaging pieces 7A between the pair of nuts 22 of the bathroom penetrating tool 2 so as to be elastically deformed, and by fitting the nuts 22 externally. At this time, the engaging piece 7B may be appropriately modified so as not to hinder the above-described operation. These operations can be easily performed by appropriately pinching the bent portions 70a and 70b.

  When the operation as described above is performed, the pair of engaging pieces 7A are externally fitted in a state in which they are pressed against the inner portions of the outer surface portions of the pair of nuts 22 by the elastic restoring force, so that the nuts 22 are not dropped off. The engaging portion 7 is engaged and held by the nut 22 so as not to easily occur. Since the engagement piece 7B is in pressure contact with the upper surface of the tubular body portion 20 of the bathroom penetrating tool 2, the engagement pieces 7A and 7B are in a state of sandwiching the nut 22 and the tubular body portion 20, and the engagement portion 7 for these portions. The engagement state becomes more reliable and strong. Therefore, the bracket B can be attached to the bathroom penetrating tool 2 in a stable state. Since the bracket B is mounted in a state straddling between the pair of nuts 22, the stability of the bracket B is further improved.

  When mounting the bracket B, the bathroom penetrating tool 2 is effectively used, and it is not necessary to use a screw member or tools. The mounting position of the bracket B is a narrow space between the bathtub 4 and the wall 42 of the bathroom, but the bracket B can be easily and appropriately mounted on the bathroom penetrating tool 2 even in such a narrow space. Is possible.

  The drain drainage unit 5 is attached to the bracket B. This attachment is easily performed by allowing the drain drainage unit 5 to enter between the pair of holding pieces 62 of the bracket body 6 and placing it on the support plate 61. Can be done. In this attached state, in addition to the movement of the drain drainage unit 5 in the left-right width direction being restricted by the pair of holding pieces 62, the bent piece 62 a is locked to the front side of the drain drainage unit 5, thereby Movement of the drainage unit 5 in the front-rear direction is also restricted. Therefore, it is possible to fix the drain drainage unit 5 without using screwing means and the like, and the drain drainage unit 5 can be easily attached to the bracket B. As described with reference to FIGS. 7 and 8, the drain drainage unit 5 can be set to any of the attachment states shown in these drawings, so that it is convenient for pipe connection to the ports P <b> 1 to P <b> 3. It is also possible to select the better direction and facilitate the piping connection work to the ports P1 to P3.

  9 and 10 show another embodiment of the present invention. In these drawings, elements that are the same as or similar to those in the above embodiment are given the same reference numerals as in the above embodiment.

  In the embodiment shown in FIG. 9A, each engaging portion 7 of the bracket B has an engaging piece 7A, but does not have a portion corresponding to the engaging piece 7B of the above embodiment. . The pair of engagement pieces 7A is configured to be able to engage and hold the nut 22 of the bathroom penetrating tool 2 only by these. Therefore, when such an engagement piece 7A is provided on the bracket B, an engagement piece corresponding to the engagement piece 7B may not be provided on the bracket B. In order to stabilize the mounting state of the bracket B with respect to the bathroom penetrating tool 2, it is preferable to provide means corresponding to the engaging piece 7B. If such means is omitted, the engaging portion 7 is engaged with the nut 22. The advantage that the workability at the time of making it better is obtained.

In the embodiment shown in FIG. 9B, the engaging piece 7A is formed in a substantially semicircular arc shape opened inward. The engaging pieces 7A are arranged so as to sandwich the pair of nuts 22 from both outer sides thereof, so that the engaging pieces 7A are fitted on the outer side surface portions of the nuts 22 and press-contacted, and can be engaged with and held by the nuts 22. In the embodiment shown in FIG. 9C, the engagement piece 7A has a substantially semicircular arc shape opened downward. Even in such a configuration, the engaging pieces 7A can be engaged with and held on the nuts 22 by fitting the engaging pieces 7A on the upper portions of the nuts 22.
As understood from these embodiments, when the engaging piece is formed in a substantially semicircular arc shape with a part opened, the direction of the opening is not particularly limited.

  In the embodiment shown in FIG. 9C, the bracket body 6 is configured to extend downward from the connecting portion 63 that connects the pair of engaging portions 7 together. Even with such a configuration, it is possible to attach the installation target device to the bracket body 6. As can be understood from the present embodiment, the bracket main body portion may be provided on the lower side instead of being provided on the upper side of the pair of engaging portions.

  In the embodiment shown in FIG. 10, a protruding portion 73 protruding toward the opening 72 side of the engaging piece 7A is provided on the concave surface 71 of each engaging piece 7A. The protrusion 73 has, for example, a substantially arc shape similar to the front view shape of the engagement piece 7A. Further, as shown in FIG. 5B, the projecting portion 73 is positioned near the rear portion in the front-rear direction of each engagement piece 7A, and the cross-sectional shape of each engagement piece 7A is substantially L-shaped. Yes. As shown in FIG. 5C, when the engaging piece 7A in the present embodiment is engaged with the nut 22, the projecting portion 73 is engaged with the step portion 28 on the back surface side of the nut 22. A packing 27 having a diameter smaller than that of the nut 22 is interposed between the nut 22 and the wall portion 42 of the bathroom, whereby the stepped portion 28 is generated. In some cases, the stepped portion 28 is filled with a caulking material (not shown). In this case, the protruding portion 73 is engaged with the caulking material and is locked to the stepped portion 28.

  According to this embodiment, the movement of the engaging piece 7A in the front-rear direction (the axial length direction of the tubular body portion 20) is restricted by the action of the protruding portion 73 engaging the stepped portion 28. If the engagement piece 7A is externally fitted so as to be in strong pressure contact with the nut 22, it is possible to prevent the engagement piece 7A from being easily displaced in the front-rear direction, but according to the present embodiment, The advantage that the displacement of the engaging piece 7A can be prevented more reliably and the mounting state of the bracket B can be further stabilized is obtained.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of each part of the bracket according to the present invention and the hot water supply system including the bracket can be variously modified within the intended scope of the present invention.

  In the above-described embodiment, the mounting target of the bracket is a bathroom penetrating tool, but other parts can be the mounting target. For example, a piping member other than the bathroom penetrating tool, a pipe body for inserting electric wiring, a bolt attached to the wall of the bathroom, and the like can be set as an attachment target (an engagement target of the bracket engagement portion). It is. In the embodiment of FIG. 3 to FIG. 8, as understood from the fact that the engagement target of the engagement portion of the bracket is both the tube portion and the nut of the bathroom penetrating device, “ The term “a pair of fixing members” is not limited to a case where a single fixing member is paired, but includes a case where a plurality of fixing members combined together form a pair. The pair of fixing members may not necessarily have the same shape and size. Therefore, the pair of engaging portions of the bracket according to the present invention are not necessarily formed symmetrically. For example, when the sizes of the pair of fixing members are different from each other, the sizes of the respective portions of the pair of engaging portions can be made to be asymmetrically different from each other.

  The engaging portion of the bracket according to the present invention may be configured to be able to engage and hold on a predetermined fixing member based on the fact that it has an engaging piece that can be elastically changed. Accordingly, when the engaging portion has a plurality of engaging pieces, each of the plurality of engaging pieces cannot be engaged and held with the predetermined fixing member by itself. Even so, it is only necessary that the entire engaging portion can be engaged and held by the fixing member by the cooperation of the plurality of engaging pieces.

  The bracket main body referred to in the present invention only needs to be able to attach an installation target device. As means for attaching the installation target device to the bracket main body, various means such as screw fixing means and wire restraint can be applied.

  Equipment other than the drainage unit can be applied as the installation target equipment. For example, a drive device unit for an automatic washing device for a bathtub, a drive device for opening and closing a bathtub stopper by remote control, and the like can be used as the installation target device, and the type thereof is not limited. The drain drainage unit referred to in the present invention is not necessarily limited to the one in which the three-way valve is accommodated in the case. For example, the three-way valve single component can be used as the drain drainage unit without accommodating the three-way valve in the container. Although the present invention is suitable for mounting an installation target device in a narrow area in a bathroom, the installation location is not limited to a narrow area and can be used in a wide area such as a washing place. In the hot water supply system according to the present invention, the specific types and configurations of the hot water supply devices are not limited, and various types of hot water supply devices can be applied.
