  The hot water supply system is configured to start a hot water filling operation at a preset temperature and water level by operating an operation terminal or a timer function, and according to the size and shape of the bath tub for such hot water filling operation. Set the relationship between the appropriate hot water supply amount and the bath water level (water level hot water amount setting). This water level hot water volume setting is performed by repeatedly checking the water level by supplying a predetermined amount of hot water to the bathtub during trial operation, increasing the number of man-hours, and setting the fuel type etc. by the contractor at the start of the trial run As a result, the number of man-hours for trial operation increases.

  However, the trial operation system of Patent Document 1 starts the trial operation of the equipment of each house at the same time, and it is necessary to individually perform opening of tap water and the setting of the equipment for the trial operation in advance. Yes, it does not reduce the number of trial runs. Therefore, the greater the number of hot water supply systems that perform trial operation, the greater the burden on the installer.

  An object of the present invention is to provide a test operation method of a hot water supply system capable of reducing the number of man-hours for the test operation.

  The invention according to claim 1 is a first hot water supply system in which a test operation is performed first among the plurality of hot water supply systems in a test operation method of a plurality of hot water supply systems having common specifications installed in a plurality of houses at the same time. A reception step for causing an external device to receive setting data reflecting the test operation result of the transmission, a transmission step for transmitting the setting data from the external device to a hot water supply system other than the first hot water supply system, and the setting data to It has the execution step which performs the trial run of hot-water supply systems other than a 1st hot-water supply system, It is characterized by the above-mentioned.

  According to the above configuration, since the test operation can be performed by sharing the setting data reflecting the test operation result in a plurality of hot water supply systems having the same specifications, the number of man-hours for the test operation can be reduced.

  According to a second aspect of the present invention, in the first aspect of the invention, the external device is a portable terminal, and the setting is performed by connecting the portable terminal to an operation terminal of the hot water supply system in the reception step and the transmission step. It is characterized by sending and receiving data.

  According to the above configuration, the setting data of the first hot water supply system can be received by the portable terminal, and the setting data can be transmitted from the portable terminal to a hot water supply system other than the first hot water supply system. Sharing is possible.

  According to a third aspect of the present invention, in the first aspect of the invention, the external device is a network-connected external server, and the operation terminal of the hot water supply system is connected to the network in the reception step and the transmission step. The setting data is transmitted and received between the two.

  According to the above configuration, when the network connection is made, the external server can receive the setting data of the first hot water supply system, and the external server can transmit the setting data to another hot water supply system. Sharing is possible.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the setting data includes at least data of a reference water level of the bathtub.

  According to the above configuration, it is possible to shorten the trial run time by omitting the supply of a predetermined amount of hot water and setting the water level for setting the reference water level of the bathtub.

  According to the trial operation method of the hot water supply system of the present invention, the number of trial operations can be reduced.

It is a figure which shows the some hot water supply system of the apartment house which concerns on the Example of this invention. It is explanatory drawing of the hot water supply system of FIG. It is a flowchart of the trial run of a 1st hot-water supply system. It is a figure which shows the water level of the bathtub at the time of trial operation. It is a flowchart of the trial run of a some hot-water supply system. It is a flowchart of the trial run of hot water supply systems other than a 1st hot water supply system. It is a flowchart which shows another example of the test run of other hot water supply systems other than a 1st hot water supply system.

  Hereinafter, modes for carrying out the present invention will be described based on examples.

  As shown in FIG. 1, in a newly built apartment house C, in many cases, a plurality of hot water supply systems 1 having specifications common to a plurality of dwelling units are installed at the same time, and trial operation of the plurality of hot water supply systems 1 is also performed at the same time. To be implemented. The hot water supply system 1 includes a hot water supply device 2, a hot water tap 3, a bathroom shower 4, a bathtub 5, an operation terminal 6, and the like, and the specifications of the hot water supply device 2 and the bathtub 5 are common to each door.

  As shown in FIG. 2, the hot water supply device 2 is an instantaneous water heater that is heated by, for example, combustion heat of fuel. The hot water supply device 2 adjusts the temperature of the supplied hot water by mixing the hot water with the hot water heated by the heating unit 11 with the mixing valve 12 and supplies the hot water with the temperature adjusted to a hot water tap or the like. 13 and a hot water filling passage 14 for branching from the hot water supply passage 13 to fill the bathtub 5 with hot water. Moreover, it has the memorial passage 15 which sends the hot water of the bathtub 5 to the heating part 11, heats it with the heating part 11, and returns it to the bathtub 5 via the hot water filling passage 14.

  The hot water supply passage 13 is provided with a hot water supply flow rate sensor 13a, a hot water supply temperature sensor (not shown), and the like. A memorial passage 15 is connected to the hot water filling passage 14 via a switching valve 16. The switching valve 16 causes the hot water supply passage 13 to communicate with the hot water filling passage 14 when hot water is supplied to the bathtub 5, and causes the chasing passage 15 to communicate with the hot water filling passage 14 at other times. A pump 17 for supplying hot water of the bathtub 5 to the heating unit 11 and a water flow switch 18 for detecting the flow of the hot water are disposed in the memorial passage 15. These various sensors, the mixing valve 12, the switching valve 16, the pump 17, the heating unit 11 and the like are connected to the control unit 20 so as to be communicable. The control unit 20 controls each operation such as trial operation, hot water supply, hot water filling, and memorial service based on the detection values of various sensors.

  The operation terminal 6 is communicably connected to the control unit 20, and from this operation terminal 6, a hot water supply set temperature in the hot water supply operation, a temperature setting such as a bath set temperature in the hot water operation and the memorial operation, and a bath water level setting in the hot water operation Etc. Further, a hot water filling operation or a memorial operation is executed by operating the operation terminal 6.

  In addition to the communication connection with the control unit 20, the operation terminal 6 includes a known wired or wireless communication means 6 a for communication connection with the external device 7. The external device 7 is a portable terminal (for example, a general-purpose or dedicated tablet PC) that can be carried by the installer or an external server connected to the network. The operation terminal 6 is configured to communicate with a portable terminal or a network-connected external server by the communication means 6a.

  The bathtub 5 is selected and installed according to the size of the bathroom to be installed from various specifications with different sizes and shapes. In order to do so, it is necessary to set in advance an appropriate water level hot water amount setting (relationship between hot water supply amount and bathtub water level). This water level hot water amount setting is performed by a trial operation of the hot water supply system 1. The water level of the bathtub 5 (the distance from the bottom surface of the bathtub 5 to the water surface) is detected by a pressure sensor 21 provided in the vicinity of the connecting portion where the memorial passage 15 or the hot water passage 14 is connected to the bathtub 5. The detected pressure of the pressure sensor 21 is proportional to the water level of the bathtub 5, and the control unit 20 has a map or the like indicating the relationship between the detected pressure and the water level and accurately acquires the water level of the bathtub 5.

Next, the trial operation of the hot water supply system 1 will be described based on the flowchart of FIG. 3 and FIG. In FIG. 3, Si (i = 1, 2,...) Represents a step.
First, in S <b> 1, the installer of the hot water supply system 1 sets the hot water supply set temperature, the type of fuel, the unit price, etc. from the operation terminal 6, closes the stopper for draining the water from the bathtub 5, and operates the operation terminal 6 And start a test run.

  Next, in S2, after supplying a predetermined amount A1 (for example, 10 L) of hot water from the hot water supply device 2 to the bathtub 5 via the hot water filling passage 14, the pump 17 of the chasing passage 15 is driven, and the hot water in the bathtub 5 is added. It is determined whether or not circulation through the culvert passage 15 and returning to the bathtub 5 is possible. This is a step for confirming that there is no hot water in the bathtub 5 that hinders the setting of the water level hot water quantity, and the circulation of the hot water in the bathtub 5 is detected by the water flow switch 18 in the additional passage 15. The amount of hot water supplied is obtained from the detected flow rate of the hot water supply flow rate sensor 13a and the detection period. If the determination is No, that is, if circulation is not detected, the pump 17 is stopped and the process proceeds to S3. On the other hand, if the determination is Yes, i.e., circulation is detected, an appropriate amount of hot water cannot be set, so the pump 17 is stopped and the process proceeds to S20.

  Next, in S3, a predetermined amount A2 (for example, 60 L) of hot water is supplied to the bathtub 5, and the process proceeds to S4. In S4, it is determined whether or not the pump 17 in the chasing passage 15 is driven to circulate hot water in the bathtub 5. If the determination is No, the pump 17 is stopped and the process proceeds to S5. In S5, a predetermined amount A3 (for example, 20 L) of hot water is supplied to the bathtub 5 and the process proceeds to S6. In S6, the number n of supply of the predetermined amount A3 is counted. To return to S4. The supply of the predetermined amount A3 is repeated until the circulation becomes possible. The number of times of supply n is set to zero at the start of trial operation.

  If the determination in S4 is Yes, the process proceeds to S7. In S7, a predetermined amount A4 (for example, 10 L) of hot water is supplied to the bathtub 5, and the process proceeds to S8. And in S8, the pump 17 of the memorial passage 15 is driven, the circulation of the hot water in the bathtub 5 is confirmed again, the pump 17 is stopped, and it progresses to S9. In S9, the current water level is set as a reference water level H1 for appropriately setting the hot water level, and the process proceeds to S10.

  Next, in S10, a predetermined amount A5 (for example, 40 L) of hot water is supplied to the bathtub 5 and the process proceeds to S11. In S11, the current water level is set to the intermediate water level H2, and the process proceeds to S12. In S12, the hot water supply amount A6 necessary for changing from the intermediate water level H2 to the target water level H3 is calculated, and the process proceeds to S13. The target water level H3 is a preset water level for other operation confirmation such as a memorial operation in a trial operation. The water level hot water amount is set from the relationship between the reference water level H1, the intermediate water level H2, and the predetermined amount A5. Based on this water level hot water amount setting, the supply amount A6 of hot water necessary for changing from the intermediate water level H2 to the target water level H3 can be calculated.

  Next, in S13, hot water of the calculated supply amount A6 is supplied to the bathtub 5 and the process proceeds to S14. In S14, it is determined whether or not the current water level is equal to or higher than a predetermined determination reference value (for example, target water level H3-10 mm). In general, the bathtub 5 is formed in a shape in which the inner wall is inclined and the opening area (area of the water surface) increases toward the upper side, so that an error due to a nonlinear relationship between the amount of hot water supplied and the water level due to this shape. The criterion value is set so as to allow If the determination is No, the process proceeds to S15. In S15, a predetermined amount A7 (for example, 2 L) of hot water is supplied to the bathtub 5 and the process proceeds to S16. In S16, the number of times of supply of the predetermined amount A7 of hot water is counted and the process returns to S14. . The supply of hot water of a predetermined amount A7 is repeated until the determination reference value is exceeded. The supply frequency m is set to zero at the start of trial operation.

  If the determination in S14 is Yes, the process proceeds to S17, the current water level is set to the operation confirmation water level H4, and the process proceeds to S18. The operation confirmation water level H4 becomes the standard water level for normal hot water filling operation after the end of the trial operation, and the amount of hot water filling is adjusted based on this water level. In S18, other operations such as a memorial operation and a hot water operation in which a certain amount of hot water is added to the bathtub 5 are confirmed, and the process proceeds to S19.

  Next, in S19, setting data reflecting the result of the test operation, such as the supply amount of hot water (A1 + A2 + A3 × n + A4) corresponding to the reference water level H1, is stored (saved), and the test operation is terminated. The set data includes data input from the operation terminal 6 by the operator such as the supply amount of hot water (A1 + A2 + A3 × n + A4 + A5 + A6 + A7 × m) corresponding to the operation confirmation water level H4 and the type and unit price of fuel supplied to the hot water supply device 2. Is also included.

  If the above-mentioned trial operation is performed individually for the hot water supply system 1 of each house in the apartment house C, the number of man-hours required to complete the trial operation of all the hot water supply systems 1 increases in proportion to the number of units, which is a burden for the installer. Become. Therefore, a trial operation method for simplifying the trial operation of the plurality of hot water supply systems 1 having the same specifications installed in the apartment house C will be described based on the flowchart of FIG. Si (i = 21, 22,...) In the figure represents a step.

  In S21, a trial operation of one appropriate hot water supply system 1 (first hot water supply system) among a plurality of hot water supply systems 1 having common specifications is performed. The trial operation of the first hot water supply system is the above-described trial operation (see FIG. 3), and S21 is a trial operation step of the first hot water supply system. When the trial operation of the first hot water supply system is completed, the process proceeds to S22.

  Next, in S22, the external device 7 receives setting data reflecting the test operation result stored in the first hot water supply system, and the process proceeds to S23. For example, a portable terminal is connected to the operation terminal 6 of the first hot water supply system as the external device 7 to receive setting data. S22 is a reception step for causing the external device 7 to receive the setting data.

  Next, in S23, the external device 7 that has received the setting data is communicatively connected to the operation terminal 6 of another hot water supply system 1 in which a trial operation other than the first hot water supply system has not been performed. It transmits to the other hot water supply system 1, and progresses to S24. S23 is a transmission step for transmitting setting data from the external device 7 to another hot water supply system 1 other than the first hot water supply system.

  Next, in S24, a test run is performed using the setting data in another hot water supply system to which the setting data has been transmitted. S24 is an execution step for executing a trial operation of another hot water supply system 1 using the setting data. The set data includes hot water supply amount data corresponding to the reference water level H1, and the specifications of the other hot water supply systems 1 are the same as those of the first hot water supply system. Trial operation can be simplified by reducing the input process. This simplified trial operation will be described based on the flowchart of FIG. Si (i = 31, 32,...) In the figure represents a step.

  In S31, the operation terminal 6 is operated to start a trial run, and the process proceeds to S32. Next, in S32, after supplying a predetermined amount A1 of hot water from the hot water supply device 2 to the bathtub 5 via the hot water filling passage 14, the pump 17 of the memorial passage 15 is driven, and the hot water of the bathtub 5 passes through the memorial passage 15. It is determined whether or not circulation that circulates and returns to the bathtub 5 is possible. If the determination is No, the pump 17 is stopped and the process proceeds to S33. If the determination is Yes, an appropriate water level cannot be set, so the pump 17 is stopped and the process proceeds to S46. In S46, the occurrence of a trial operation error is notified to the installer, and the process is terminated.

  Next, in S33, a supply amount (A2 + A3 × n + A4) of hot water which is additionally supplied to A1 already supplied in S31 and becomes the reference water level H1 included in the setting data is supplied to the bathtub 5, and the process proceeds to S34. In S34, it is determined whether or not the difference between the current water level and the reference water level H1 is within a predetermined reference range (for example, within ± 5 mm). If the determination is No, that is, if there is a possibility that some trouble has occurred and the reference water level H1 of the setting data is not reached, the process proceeds to S46. If the determination is Yes, the process proceeds to S35, where the current water level is set as the reference water level H1 of the hot water supply system 1 in S35, and the process proceeds to S36. The setting up to the reference water level H1 is simplified, and the time required up to this point is shortened.

  Next, in S36, a predetermined amount A5 of hot water is supplied to the bathtub 5 and the process proceeds to S37. In S37, the current water level is set to the intermediate water level H2, and the water level hot water amount is set and the process proceeds to S38. In S38, the supply amount A6 of hot water required for changing from the intermediate water level H2 to the target water level H3 based on the water level hot water amount setting is calculated, and the process proceeds to S39.

  Next, in S39, hot water of the calculated supply amount A6 is supplied to the bathtub 5 and the process proceeds to S40. In S40, it is determined whether or not the current water level is equal to or higher than a determination reference value (for example, target water level H3-10 mm). If the determination is No, the process proceeds to S41. In S41, the predetermined amount A7 of hot water is supplied to the bathtub 5 and the process proceeds to S42. In S42, the number m of supply of the predetermined amount A7 is counted, and the process returns to S40. The supply frequency m is set to zero at the start of trial operation.

  If the determination in S40 is Yes, the process proceeds to S43, the current water level is set to the operation confirmation water level H4, and the process proceeds to S44. In S44, other operations such as memorial service and hot water are confirmed, and the process proceeds to S45. In S45, setting data reflecting the result of the test operation is stored, and the test operation is terminated.

Next, an example of a further simplified test operation in the execution step will be described based on the flowchart of FIG. Si (i = 51, 52,...) In the figure represents a step.
In S51, the operation terminal 6 is operated to start a trial run, and the process proceeds to S52. Next, in S52, after supplying a predetermined amount A1 of hot water from the hot water supply device 2 to the bathtub 5 via the hot water filling passage 14, the pump 17 of the memorial passage 15 is driven, and the hot water of the bathtub 5 passes through the memorial passage 15. It is determined whether or not circulation that circulates and returns to the bathtub 5 is possible. If the determination is No, the pump 17 is stopped and the process proceeds to S53. If the determination is Yes, an appropriate water level cannot be set, so the pump 17 is stopped and the process proceeds to S63. In S63, the occurrence of a trial operation error is notified to the installer, and the process is terminated.

  Next, in S53, a supply amount (A2 + A3 × n + A4) of hot water which is additionally supplied to A1 already supplied in S51 and becomes the reference water level H1 included in the setting data is supplied to the bathtub 5, and the process proceeds to S54. In S54, it is determined whether or not the difference between the current water level and the reference water level H1 is within a predetermined reference range (for example, within ± 5 mm). If the determination is No, the process proceeds to S63. If the determination is Yes, the process proceeds to S55, where the current water level is set as the reference water level H1 of the hot water supply system 1 in S55, and the process proceeds to S56. The setting up to the reference water level H1 is simplified, and the time required up to this point is shortened.

  Next, in S56, hot water of the supply amount (A5 + A6) necessary for changing from the reference water level H1 to the target water level H3 is supplied to the bathtub 5, and the process proceeds to S57. This hot water supply amount (A5 + A6) is included in the setting data. If the first hot water supply system has the same specifications as the other hot water supply systems 1, the same water level hot water amount setting is used, so the current water level should be the operation confirmation water level H4, and the operation confirmation water level H4 is simplified. And the required time is shortened.

  Next, in S57, it is determined whether or not the current water level is equal to or higher than a determination reference value (for example, target water level H3-10 mm). When the determination is No, the process proceeds to S58, and in S58, the predetermined amount A7 of hot water is supplied to the bathtub 5 and the process proceeds to S59. In S59, the number m of supply of the predetermined amount A7 is counted, and the process returns to S57. The supply frequency m is set to zero at the start of trial operation.

  If the determination in S57 is Yes, the process proceeds to S60, and the current water level is set to the operation confirmation water level H4 in S60, and the process proceeds to S61. In S61, other operations such as memorial service and hot water are confirmed, and the process proceeds to S62. In S62, setting data reflecting the result of the test operation is stored, and the test operation is terminated.
