  Hereinafter, an embodiment of the present invention will be described with reference to FIG. In this Embodiment, it is actualized about the hot water supply system applied to buildings, such as a house. FIG. 1 is a schematic view showing a building.

  The building 10 is a two-story building, and has a kitchen 11 provided on the first floor portion of the building 10, a washroom 12 and a bathroom 13 provided on the second floor portion, and hot water is supplied to each place by a hot water supply system 50. It becomes the composition which is done. In addition, in this Embodiment, although the building 10 was made into two stories, it is not limited to this. It may be a one-story building, or three or more stories.

  The hot water supply system 50 includes a hot water supply device 51 disposed outdoors. The hot water supply device 51 is connected to a water pipe via a water distribution pipe, and is configured to warm water supplied from the water pipe so as to reach a predetermined temperature. The hot water supply device 51 is connected to a spout 21 attached to the bathroom 13 (bath unit) via a hot water supply pipe 52, and hot water heated by the hot water supply device 51 is supplied to the spout 21 through the hot water supply pipe 52. It has a configuration.

  A hot water supply pipe 53 is connected to the hot water supply apparatus 51 in parallel with the hot water supply pipe 52. The hot water supply pipe 53 is branched into hot water supply pipes 55 to 57 at a header 54 (corresponding to a “branch point”). The hot water supply pipe 55 is connected to the spout 22 attached to the kitchen 11 (kitchen equipment), the hot water supply pipe 56 is connected to the spout 23 attached to the washroom 12 (wash basin), and the hot water pipe 57 is connected to the bathroom 13 (shower equipment). ) Is connected to the water outlet 24 attached. The hot water heated by the hot water supply device 51 is supplied to the water discharge ports 22 to 24 through the hot water supply pipes 55 to 57.

  Thus, by providing a hot water supply path for a bus unit that requires a relatively large amount of hot water separately from the other hot water supply paths, the amount of hot water supplied to the other outlets 22 to 24 and the water pressure during hot water filling are affected. It is restrained from reaching.

  The hot water supply pipes 52, 55 to 57 shown in the present embodiment are provided with a sensor unit 70 as a measuring means for measuring the amount of heat. As shown in the schematic diagram of FIG. 2, the sensor unit 70 includes a temperature sensor 71 that measures the hot water temperature and a flow rate sensor 72 that measures the flow rate. A manual on-off valve is provided on the upstream side and downstream side of the sensor unit 70, and consideration is given to convenience during maintenance of the sensor unit 70.

  A child radio module 75 is disposed around the sensor unit 70. The temperature sensor 71 and the flow rate sensor 72 are connected to the child radio module 75 via wirings 73 and 74, and the child radio module 75 is arranged slightly away from the hot water supply pipe. Such an arrangement is advantageous for protecting the child radio module 75 and the like.

  The child radio module 75 has a calculation unit that calculates the amount of hot water supply in the corresponding hot water supply pipe based on information from the temperature sensor 71 and the flow rate sensor 72, and functions as a calorimeter. A sensor block 81 (corresponding to a “measurement unit”) constituted by the temperature sensor 71, the flow rate sensor 72, and the child radio module 75 corresponds to the hot water supply pipes 52, 55 to 57 on a one-to-one basis. Here, with reference to FIG. 3, the electrical configuration (measurement system) according to the hot water supply system 50 will be described.

  Child radio module 75A attached to the hot water supply pipe 52 for the bath unit, child radio module 75B attached to the hot water supply pipe 55 for the kitchen equipment, child radio module 75C attached to the hot water supply pipe 56 for the wash basin, hot water pipe for the shower The child wireless module 75D attached to 57 is disposed within the communication range of the parent wireless module 76 (corresponding to a repeater), and can wirelessly communicate with the parent wireless module 76. The parent wireless module 76 is connected to the home server 78 via the LAN cable 79 and forms a control block 82 together with the home server 78. It forms communication means between the child radio modules 75A to 75D, the parent radio module 76, the sensor block 81, and the control block 82. Information from each sensor block 81 is input to the home server 78 through the parent radio module 76. . In the present embodiment, information related to the water supply temperature (the temperature of water supplied to the hot water supply device 51) is input to the child wireless module 75 from the home server 78 through the parent wireless module 76. The sub wireless module 75 refers to the water supply temperature when calculating the amount of heat.

  The home server 78 grasps the hot water usage status at the water outlets 21 to 24 based on the information input from the sensor block 81. When the hot water supply is stopped, the hot water remains in the hot water supply pipe. This hot water gradually loses heat under the influence of the outside and returns to room temperature after a certain period of time. On the other hand, when the water outlet is not completely closed due to the user forgetting to tighten, the hot water in the hot water supply pipe returns to room temperature in a shorter period than usual due to leakage of hot water from the water outlet. The home server 78 monitors whether such a situation has occurred, and if it is determined that the event has occurred, the home server 78 notifies the user of a message prompting the user to check the spout.

  Further, in the present embodiment, the hot water supply device 51 does not operate in a state where the water discharge ports 21 to 24 are slightly open, and the supply of hot water is avoided. Even when it is determined that water has been supplied over a long period of time based on information from the sensor block 81, a message prompting the user to confirm the water outlet is displayed. Notify

  Here, in the present embodiment, information from a plurality of sensor blocks 81 (child radio modules 75) is collected by one parent radio module 76. Hereinafter, with reference to FIG. 1 and FIG. 4, the arrangement of the sensor unit 70 and the configuration related thereto will be described supplementarily.

  As shown in FIG. 1, hot water supply pipes 52 and 53 extending from a hot water supply device 51 installed outdoors are inserted into the underfloor space LE of the building 10 from the outdoors. The building 10 is provided with a pipe shaft 30 that connects the underfloor space LE and the interstory space ME. The hot water supply pipes 52 and 53 reach the second floor through the pipe shaft 30. The pipe shaft 30 is inserted with not only the hot water supply pipes 52 and 53 but also a drain pipe 35 through which drainage from the second floor portion passes.

  The branch point (header 54) in the hot water supply pipe 53 is arranged in the underfloor space LE, and the hot water supply pipe 53 branches into the hot water supply pipes 55 to 57 on the near side inserted through the pipe shaft 30. About the said sensor part 70, the use condition of the hot water in the hot water supply pipes 55-57 can be grasped | ascertained separately by arrange | positioning in the position which becomes a downstream (water outlet side) rather than a branch location.

  The pipe shaft 30 passes through a position adjacent to the spout 22 attached to the kitchen facility, and the hot water supply pipe 55 is connected to the spout 22 through an opening formed in the middle of the pipe shaft 30. The other hot water supply pipes 52, 56, 57 reach the interstory space ME via the pipe shaft 30, and are connected to the respective outlets 21, 23, 24 on the second floor part via the interstory space ME. ing.

  Here, the distance between the hot water supply pipes 52 and 55 to 57 in the pipe shaft 30 is smaller than the distance between the hot water supply pipes 52 and 55 to 57 in the underfloor space LE and the inter-floor space ME. At 30, the hot water supply pipes 52 and 55 to 57 are in a state of being close to each other. That is, the arrangement of the hot water supply pipes is “dense” in the pipe shaft 30 as compared with other parts in the building 10. In the present embodiment, the portion inserted through the pipe shaft 30 in the hot water supply pipes 52, 55 to 57 corresponds to the “predetermined portion”.

  The above-described sensor units 70A to 70D are disposed in the pipe portions passing through the pipe shaft 30 through the hot water supply pipes 52 and 55 to 57, respectively. More specifically, as shown in FIG. 4, sensor portions 70 </ b> A to 70 </ b> D are arranged in portions adjacent to the water discharge port 22 of the first floor portion (for kitchen equipment) in each of the hot water supply pipes 52 and 55 to 57. In order to improve the response of the sensor unit 70, it is advantageous to dispose the sensor unit 70 as close to the water outlet as possible. The kitchen facility provided with the water outlet 22 is installed on the floor, and the position of the water outlet 22 is close to the second floor portion. In this way, by pulling up the location where the sensor unit 70 is disposed to a height position equivalent to the water discharge port 22, it is possible to suppress the decrease in the responsiveness.

  In the configuration in which the sensor unit 70 and the child radio module 75 are connected via the wirings 73 and 74, shortening the lengths of the wirings 73 and 74 is advantageous in improving the measurement accuracy. In view of such circumstances, the arrangement of the child radio module 75 depends on the arrangement of the sensor unit 70. As described above, it is possible to bring the child radio modules 75 closer to each other by arranging the sensor unit 70 in a portion where the hot water supply pipes 52 and 55 to 57 are close to each other, that is, by arranging the sensor units 70 close to each other. It has become.

  As shown by the one-dot chain line in FIG. 4, the communication range CE of the parent wireless module 76 is limited. However, with the above-described arrangement, a plurality (all) of communication ranges CE of one parent wireless module 76 are included. The child wireless modules 75A to 75D are integrated, and the communication function between each child wireless module 75A to 75D and the parent wireless module 76 is established.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  If the sensor block 81 and the control block 82 can be wirelessly communicated with each other, it is not necessary to carry out wiring or the like for electrically connecting the sensor block 81 and the control block 82, and it is possible to contribute to improvement of work efficiency at the time of construction. Here, in the building 10, building improvements such as walls and floors can be obstacles that hinder upper communication. For this reason, restrictions on the communication range tend to become strong. Such a problem can be solved by providing the master wireless module 76 for each sensor block 81 (each hot water supply pipe), but if such a countermeasure is taken, the measurement system can become large. There is concern that this will hinder the spread of measurement systems. In this regard, as shown in the present embodiment, if the sensor unit 70 is arranged in a portion where the hot water supply pipes are close to each other, the parent radio that constitutes the communication means together with the child radio module 75 attached to the sensor unit 70. The module 76 can be shared. This is preferable for simplifying the measurement system by reducing the number of parent wireless modules 76.

  In the configuration in which the hot water supply path for supplying hot water to each of the water discharge ports 22 to 24 is divided by branching the hot water supply tube 53, the hot water supply tubes 55 to 57 are separated from each other as they approach the water discharge ports 22 to 24. . In view of such a situation, if the hot water supply pipes 55 to 57 are forced to approach each other at a position close to the water discharge ports 22 to 24, the hot water supply path may become distorted. On the other hand, it is inevitable that the hot water supply pipes are close to each other at a position close to the branch point (header 54). Therefore, as shown in the present embodiment, by setting the location where the sensor unit 70 is located near the branch location, it is possible to prevent the hot water pipe from being complicated in order to enjoy the above-described effects. .

  If the hot water supply pipe 52 in parallel with the hot water supply pipe 53 is configured to approach the hot water supply pipe 53 on the downstream side (water discharge port side) of the branch point of the hot water supply pipe 52, the hot water supply pipe 52 is used. The parent radio module 76 can be shared by the sensor blocks 81B to 81D and the sensor block 81A for the hot water supply pipe 53. Thereby, it can contribute to the further simplification of a measurement system.

  The rising portions of the hot water supply pipes 52 and 53 are accommodated in the pipe shaft 30. About pipe shaft 30, since other composition, such as drain pipe 35, is inserted, if it is going to insert a plurality of hot-water supply pipes 52 and 53, those hot-water supply pipes will be in the state where they approached. Then, if it is set as the structure which arrange | positions the sensor part 70 in these approaching parts, it can suppress suitably that the handling of a hot water supply pipe becomes complicated when implement | achieving the collective arrangement | positioning of the sensor part 70. FIG.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows. Incidentally, the configuration of another embodiment described below may be applied individually to the configuration in the above embodiment, or may be applied in combination with each other.

  (1) In the above embodiment, the hot water supply pipes 52 and 55 to 57 are gathered in the pipe shaft 30 and the hot water supply pipes 52 and 55 to 57 are brought closer to each other as compared with the outside of the pipe shaft 30. In addition, a sensor unit 70 (corresponding to “sensor”) is disposed in a portion inserted through the pipe shaft 30. For example, in a configuration in which the distance between the hot water supply pipes is reduced (approached) in the underfloor space LE or the interstory space ME, the sensor unit 70 can be disposed in a portion where the distance is reduced.

  (2) In the above embodiment, the hot water supply pipe 53 is branched at the header 54, and the sensor unit 70 is disposed on the downstream side (water outlet side) of the header 54. However, the present invention is not limited to this. It is not something. As shown in the schematic diagram of FIG. 5A, the sensor unit 70 can be disposed at a portion upstream of the header 54 (on the hot water supply device side). In this case, the location where the sensor unit 70 is disposed in the hot water supply pipe 53 and the hot water supply pipe 52 are brought close to each other, and the sensor unit 70 attached to the hot water supply pipe 52 is also arranged in the location where the sensor part 70 is approaching. . Thereby, sharing of the parent wireless module 76 can be realized for the sensor unit 70 attached to the hot water supply pipe 52 and the sensor unit 70 attached to the hot water supply pipe 53.

  (3) In the above-described embodiment, the sensor block 81 is disposed in a portion passing through the first floor portion of the hot water supply pipes 52, 56 to 57 for the water outlet of the second floor portion. However, the present invention is not limited to this. Absent. It is also possible to arrange the sensor block 81 in a portion passing through the second floor portion of the hot water supply pipes 52, 56 to 57. Since the first floor portion and the second floor portion are partitioned by the ceiling, wireless communication is likely to be hindered. Therefore, when making such a change, it is preferable to use the parent wireless module 76 corresponding to the first floor part and the parent wireless module 76 corresponding to the second floor part together, and divide the information acquisition targets for each hierarchy.

  (4) In the above embodiment, the sensor blocks 81B to 81D (specifically, the child radio modules 75B to 75D) attached to the hot water pipes 55 to 57 and the sensor block 81A (specifically, the child radio module to the hot water pipe 52). 75A) is arranged in the communication range CE of one parent wireless module 76 and the parent wireless module 76 is shared, but is not limited to this. In order to share the parent wireless module 76 for at least a plurality of sensor blocks 81, it is sufficient if the sharing of the parent wireless module 76 is achieved for the sensor blocks 81B to 81D attached to the hot water supply pipes 55 to 57. For the hot water supply pipes 52 having different hot water supply paths, it is not denied that the parent wireless module 76 is provided separately.

  (5) In the above embodiment, the hot water supply pipe 52 is configured to be close to the hot water supply pipe 53 (hot water supply pipes 55 to 57), but the hot water supply pipe 52 and a part of the hot water supply pipes 55 to 57 are configured to be close to each other. It is also possible to divide the sensor unit 70 group into two. In this case, a parent wireless module 76 may be provided for each set.

  (6) In the above embodiment, the hot water supply path dedicated to the hot water filling is constructed by the hot water supply pipe 52, but the hot water supply pipe 52 may be divided into a plurality of branches in the same manner as the hot water supply pipe 53. For example, the hot water supply pipe 52 may be branched to supply hot water to the hot water outlet and the shower water outlet. In this case, the portion that is downstream of the branch position in the hot water supply pipe 52 and the portion that is downstream of the branch position in the hot water supply pipe 53 are brought close to each other so that each sensor unit 70 is within the communication range of one parent wireless module. It is good to arrange in.

  (7) In the above embodiment, the pipe shaft 30 passes through the vicinity of the spout 22 attached to the kitchen 11, but the position of the pipe shaft 30 is arbitrary. However, when various processes such as confirmation of water leakage are performed based on the information from the sensor block 81 as described above, it is preferable to arrange the sensor block 81 as close to the water outlet as possible in view of improvement in responsiveness. Paying attention to the point that the water discharge port 22 is above the floor surface, that is, closer to the second floor portion, when there are water discharge ports on both the first floor portion and the second floor portion, close to the water discharge port on the first floor portion. It is advantageous to dispose the pipe shaft so as to pass through in order to realize the centralized arrangement of the sensor units 70 on the pipe shaft and to improve the responsiveness.

  (8) The home server 78 described in the above embodiment is configured to check for water leakage based on information from the sensor block 81 and notify the user of water leakage confirmation as necessary. Is not to be done. For example, a configuration in which the amount of hot water used at each water outlet is grasped based on information from the sensor block 81 and how much hot water is used at which water outlet can be configured.

  (9) The sensor block 81 shown in the above embodiment has a configuration in which the sensors 71 and 72 and the child radio module 75 are separated and connected by the wirings 73 and 74. However, the present invention is not limited to this. Is not to be done. It is also possible to have a configuration in which the sensors 71 and 72 and the child radio module 75 are integrated and the unit is attached to the hot water supply pipe.

  (10) In the above embodiment, the case where the temperature sensor 71 and the flow sensor 72 are used in combination is exemplified, but the type and number of sensors are not limited to those described above. For example, only one of the temperature sensor 71 and the flow rate sensor 72 may be provided.
