Description

The present invention relates to a method of trial operation of a hot water supply system provided with a hot water supply device and a bathtub, and more particularly to a method of trial operation of a plurality of hot water supply systems having common specifications such as a condominium.

Conventionally, a hot water supply system consisting of a hot water supply device, a hot water tap, a shower in a bathroom, a bathtub, etc. has been installed in a house. The hot water supply system newly introduced by new construction or renovation of a house will be tested for operation after the installation work is completed.

In many cases, such as newly built condominiums and detached houses built in one area, hot water supply systems with the same specifications are installed in each house at the same time. Since the trial run of these multiple hot water supply systems is performed individually for each house, it is a burden on the installer.

As a technique for reducing the burden in such a test run, for example, as in Patent Document 1, the equipment of each house including the hot water supply system is connected to the network, and the test run of the equipment of each house is performed from an external server via the network. A test run system to start is known.

Japanese Unexamined Patent Publication No. 2007-32930

The hot water supply system is configured to be able to start hot water filling operation with preset temperature and water level by operating the operation terminal or timer function, and in the trial run, depending on the size and shape of the bathtub for such hot water filling operation. Set the relationship between the appropriate amount of hot water supply and the bathtub water level (water level hot water amount setting). This water level hot water amount setting is set by repeatedly supplying a predetermined amount of hot water to the bathtub and checking the water level during the test run, which increases the man-hours and the setting process of the fuel type etc. by the builder at the start of the test run. Therefore, the man-hours for trial run will increase.

However, the test run system of Patent Document 1 starts the test run of the equipment of each house all at once, and it is necessary to open the tap water for the test run and set the equipment individually in advance. Yes, it does not reduce the number of test run steps. Therefore, the greater the number of hot water supply systems for trial operation, the greater the burden on the installer.

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

The invention of claim 1 is a first hot water supply system in which a trial run is first performed among the plurality of hot water supply systems in a method of trial operation of a plurality of hot water supply systems having common specifications installed in a plurality of houses at the same time.

It is characterized by having an execution step of executing a trial run of a hot water supply system other than the first hot water supply system.

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

The invention of claim 2 is the invention of claim 1, wherein the external device is a portable terminal, and the portable terminal is communicatively connected to the operation terminal of the hot water supply system in the reception step and the transmission step. It is characterized by sending and receiving data.

The invention of claim 3 is the invention of claim 1, wherein the external device is a network-connected external server, and the operation terminal of the hot water supply system is network-connected to the external server in the reception step and the transmission step. It is characterized in that the setting data is transmitted and received between the two.

According to the above configuration, when the network is connected, 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. It can be shared.

The invention of claim 4 is characterized in that, in the invention of any one of claims 1 to 3, the setting data includes at least data of a reference water level of a bathtub.

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

According to the test run method of the hot water supply system of the present invention, the man-hours for the test run can be reduced.

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

Hereinafter, embodiments for carrying out the present invention will be described with reference to examples.

As shown in FIG. 1, in many cases, a plurality of hot water supply systems 1 having the same specifications for a plurality of dwelling units are installed in the newly built apartment building C at the same time, and the trial operation of the plurality of hot water supply systems 1 is also performed at the same time. Will be implemented in. The hot water supply system 1 is composed of 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 house.

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

A hot water supply flow rate sensor 13a, a hot water supply temperature sensor (not shown), and the like are arranged in the hot water supply passage 13. A reheating passage 15 is connected to the hot water filling passage 14 via a switching valve 16. The switching valve 16 communicates the hot water supply passage 13 with the hot water filling passage 14 when supplying hot water to the bathtub 5, and communicates the reheating passage 15 with the hot water filling passage 14 at other times. The reheating passage 15 is provided with a pump 17 for supplying the 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. These various sensors, a mixing valve 12, a switching valve 16, a pump 17, a heating unit 11, and the like are communicably connected to the control unit 20. The control unit 20 controls each operation such as test run, hot water supply, hot water filling, and reheating based on the detected values of various sensors.

The operation terminal 6 is communicably connected to the control unit 20, and the temperature setting such as the hot water supply set temperature in the hot water supply operation, the bathtub set temperature in the hot water filling operation and the reheating operation, and the bathtub water level setting in the hot water filling operation are set from the operation terminal 6. And so on. In addition, the hot water filling operation, the reheating operation, and the like are executed by the operation of 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 6a 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 or the like) that can be carried by the installer, or an external server connected to a network. The operation terminal 6 is configured to communicate with a portable terminal or an external server connected to a network by the communication means 6a.

Since the bathtub 5 is selected and installed according to the size of the bathroom to be installed from among various specifications having different sizes and shapes, the bathtub 5 is filled with hot water up to the bathtub water level set in the hot water filling operation. Therefore, it is necessary to set an appropriate water level hot water amount (relationship setting between the hot water supply amount and the bathtub water level) in advance. This water level hot water amount setting is performed in the trial run of the hot water supply system 1. The water level of the bathtub 5 (distance from the bottom surface of the bathtub 5 to the water surface) is detected by a pressure sensor 21 arranged in the vicinity of the connection portion where the reheating passage 15 or the hot water filling 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 showing the relationship between the detected pressure and the water level, and accurately acquires the water level of the bathtub 5.

Next, the trial run of the hot water supply system 1 will be described with reference to the flowchart of FIG. 3 and FIG. Si (i = 1, 2, ...) In FIG. 3 represents a step.
First, in S1, 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 the trial run.

Next, in S2, after supplying a predetermined amount of hot water of A1 (for example, 10 L) from the hot water supply device 2 to the bathtub 5 via the hot water filling passage 14, the pump 17 of the reheating passage 15 is driven, and the hot water of the bathtub 5 is added. It is determined whether or not it is possible to circulate through the heating passage 15 and return to the bathtub 5. This is a step of confirming that the bathtub 5 does not have hot water that hinders the setting of the water level, and the circulation of the hot water in the bathtub 5 is detected by the water flow switch 18 of the reheating 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 thereof. When the determination is No, that is, when circulation is not detected, the pump 17 is stopped and the process proceeds to S3. On the other hand, if the determination is Yes, that is, when circulation is detected, the pump 17 cannot be set appropriately, so the pump 17 is stopped and the process proceeds to S20.

Next, in S3, a predetermined amount of hot water A2 (for example, 60 L) is supplied to the bathtub 5 to proceed to S4. Then, in S4, the pump 17 of the reheating passage 15 is driven to determine whether or not the hot water of the bathtub 5 can be circulated. If the determination is No, the pump 17 is stopped and the process proceeds to S5. In S5, the bathtub 5 is supplied with hot water of a predetermined amount A3 (for example, 20 L) and proceeds to S6. And return to S4. The supply of the predetermined amount A3 is repeated until circulation becomes possible. The number of times of supply n is set to zero at the start of the trial run.

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

Next, in S10, a predetermined amount of hot water of A5 (for example, 40 L) is supplied to the bathtub 5 to proceed to S11, and in S11, the current water level is set to the intermediate water level H2 and the process proceeds to S12. Then, in S12, the supply amount A6 of hot water required to reach the target water level H3 from the intermediate water level H2 is calculated, and the process proceeds to S13. The target water level H3 is a preset water level for confirming other operations such as reheating operation in the test run. 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, and the hot water supply amount A6 required to make the target water level H3 from the intermediate water level H2 can be calculated based on this water level hot water amount setting.

Next, in S13, the calculated hot water of the supply amount A6 is supplied to the bathtub 5, and the process proceeds to S14. Then, 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, the target water level H3-10 mm). Generally, the inner wall of the bathtub 5 is inclined, and the opening area (water surface area) becomes larger toward the upper side. Therefore, an error due to the non-linear relationship between the amount of hot water supplied and the water level due to this shape is formed. The judgment standard value is set so as to allow. If the determination is No, the process proceeds to S15, in S15, a predetermined amount of hot water of A7 (for example, 2 L) is supplied to the bathtub 5 and the process proceeds to S16. .. The supply of hot water of a predetermined amount A7 is repeated until the value becomes equal to or higher than the judgment reference value. The number of times of supply m is set to zero at the start of the trial run.

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 test run is completed, and the hot water filling amount is adjusted based on this water level. Then, in S18, other operations such as a reheating 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, the setting data reflecting the result of the trial run, such as the supply amount of hot water corresponding to the reference water level H1 (A1 + A2 + A3 × n + A4), is stored (saved) and the trial run is terminated. This setting data includes data input from the operation terminal 6 such as the amount of hot water supplied (A1 + A2 + A3 × n + A4 + A5 + A6 + A7 × m) corresponding to the operation confirmation water level H4, the type and unit price of the fuel supplied to the hot water supply device 2. Is also included.

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

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

Next, in S22, the external device 7 receives the setting data reflecting the test run result stored in the first hot water supply system, and the process proceeds to S23. For example, as the external device 7, the portable terminal is connected to the operation terminal 6 of the first hot water supply system by communication to receive the 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 connected to the operation terminal 6 of the other hot water supply system 1 that has not been commissioned other than the first hot water supply system by communication, and the setting data is transmitted from the external device 7. It is transmitted to another hot water supply system 1 and proceeds to S24. S23 is a transmission step of causing the external device 7 to transmit the setting data to another hot water supply system 1 other than the first hot water supply system.

Next, in S24, in another hot water supply system to which the setting data is transmitted, a trial run is performed using the setting data. S24 is an execution step of executing a trial run of another hot water supply system 1 using the setting data. The setting data includes data on the amount of hot water supplied equivalent to the reference water level H1, and the other hot water supply system 1 has the same specifications as the first hot water supply system. The input process can be reduced and the trial run can be simplified. This simplified test run will be described with reference to the flowchart of FIG. Si (i = 31, 32, ...) In the figure represents a step.

In S31, the operation terminal 6 is operated to start the test run and proceed to S32. Next, in S32, after supplying a predetermined amount of hot water of A1 from the hot water supply device 2 to the bathtub 5 via the hot water filling passage 14, the pump 17 of the reheating passage 15 is driven, and the hot water of the bathtub 5 passes through the reheating passage 15. It is determined whether or not the 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, the appropriate water level and hot water amount cannot be set, so the pump 17 is stopped and the process proceeds to S46, and the installer is notified of the error occurrence of the test run in S46 and the process ends.

Next, in S33, hot water of a supply amount (A2 + A3 × n + A4) that 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 proceeds to S34. Then, 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 the reference water level H1 of the setting data has not been reached due to some trouble, the process proceeds to S46. If the determination is Yes, the process proceeds to S35, and in S35, the current water level is set as the reference water level H1 of the hot water supply system 1 and the process proceeds to S36. The setting of the reference water level H1 is simplified, and the time required up to this point is shortened.

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

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

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. Then, in S44, other operations such as reheating and hot water are confirmed, and the process proceeds to S45. In S45, the setting data reflecting the result of the test run is stored and the test run is completed.

Next, an example of a more simplified test run in the execution step will be described with reference to the flowchart of FIG. Si (i = 51, 52, ...) In the figure represents a step.
In S51, the operation terminal 6 is operated to start the test run and proceed to S52. Next, in S52, after supplying a predetermined amount of hot water of A1 from the hot water supply device 2 to the bathtub 5 via the hot water filling passage 14, the pump 17 of the reheating passage 15 is driven, and the hot water of the bathtub 5 passes through the reheating passage 15. It is determined whether or not the 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, the water level and the amount of hot water cannot be set appropriately, so the pump 17 is stopped and the process proceeds to S63, and the installer is notified of the error occurrence of the test run in S63 and the process ends.

Next, in S53, hot water of a supply amount (A2 + A3 × n + A4) that 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 proceeds to S54. Then, 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, and in S55, the current water level is set as the reference water level H1 of the hot water supply system 1 and the process proceeds to S56. The setting of 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) required to change from the reference water level H1 to the target water level H3 is supplied to the bathtub 5 and the process proceeds to S57. The amount of hot water supplied (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 water level is the same, so the current water level should be the operation confirmation water level H4, and even the operation confirmation water level H4 setting 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 the determination reference value (for example, the target water level H3-10 mm). If the determination is No, the process proceeds to S58, in S58, the bathtub 5 is supplied with hot water of a predetermined amount A7 and proceeds to S59, and in S59, the number of times of supply m of the predetermined amount A7 is counted and the process returns to S57. The number of times of supply m is set to zero at the start of the trial run.

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

Next, the operation and effect of the test run method of the hot water supply system of the present invention will be described.
The test run method of the hot water supply system of the present invention is other than the reception step of causing the external device 7 to receive the setting data reflecting the test run result of the first hot water supply system that was first tested, and the external device 7 to the first hot water supply system. It includes a transmission step of causing another hot water supply system 1 to transmit the setting data, and an execution step of executing a trial run of another hot water supply system 1 other than the first hot water supply system using the setting data. Therefore, since the setting data reflecting the test run result of the first hot water supply system can be shared by the plurality of hot water supply systems 1 having the same specifications and the test run can be performed in the execution step, the man-hours for the test run can be reduced. be.

When the external device 7 is a portable terminal, the portable terminal is connected to the operation terminal 6 of the hot water supply system 1 for communication in the reception step and the transmission step to transmit and receive setting data. Therefore, the setting data can be shared via the portable terminal, and the setting data can be shared to reduce the man-hours for the trial run.

When the external device 7 is an external server connected to a network, the operation terminal 6 of the hot water supply system 1 is connected to the network in the reception step and the transmission step to transmit and receive setting data to and from the external server. Therefore, the setting data can be shared via the external server, and the setting data can be shared to reduce the man-hours for the trial run.

The setting data includes at least the data of the reference water level H1 of the bathtub 5. Therefore, it is possible to shorten the test run time by omitting the repetition of supplying a predetermined amount of hot water and checking the water level for setting the reference water level H1 of the bathtub 5. Further, the setting data also includes data such as the type of fuel input by the installer from the operation terminal 6, and the burden of individually setting these in the plurality of hot water supply systems 1 can be reduced.

We explained the test run method of multiple hot water supply systems with the same specifications of apartment house C, but it also applies to multiple hot water supply systems with the same specifications installed in multiple detached condominiums built together in one area. It is possible. Further, the hot water supply device 2 may be a hot water storage type water heater. In addition, a person skilled in the art can carry out the present invention in a form in which various modifications are added to the above embodiment without departing from the spirit of the present invention, and the present invention includes such modified forms.
