Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling a bath system in which a circulation adapter is installed in a bathtub, and the bathtub and a heat source are connected via a circulation pipe connected to the circulation adapter.

[0002]

2. Description of the Related Art Conventionally, as a bath system, a bathtub with a water heater and a bathtub are connected to each other by a circulation pipe, and hot water in the bathtub is forcibly circulated between the bathtub and the waterbath by the operation of a circulation pump. It is generally known that this makes it possible to reheat the hot water in the bathtub. In such a bath system, a circulation adapter having a water intake port and a water discharge port is installed on the bathtub side, and the bathtub-side end of a circulation pipe extending from the bathtub with the water heater is connected to the circulation adapter. . Then, hot or cold water of a predetermined temperature is poured into the bathtub through a part or all of the circulation pipe from the bath kettle with the water heater, and is filled with water to a predetermined water level. The above hot water filling and reheating are automatically controlled by operating and controlling various devices such as a heating unit and a circulating pump mainly based on a predetermined control program or a control circuit built in a controller of a bath water heater. Often executed in.

In such a bath system, FIG.
As shown in the figure, the circulation adapter 11 is generally installed at a side position near the bottom surface of the bathtub 100, and the water inlet and the water discharge port of the circulation adapter 11 are usually slightly smaller than the bottom position. At the upper position. Therefore, the filling control by the controller 5 ′ is also performed depending on the installation position of the circulation adapter 11. That is, since it is unknown whether there is residual water or whether the level of the residual water is above or below the circulation adapter 11, first, a predetermined test amount of molten metal is poured, and then the circulation pump is operated to activate the circulation pipe 300. By performing a circulation determination process for determining whether or not a circulating flow due to hot and cold water in the bathtub occurs, it is determined whether the water level in the bathtub after pouring is above or below the position of the circulation adapter 11. If it is below, it is determined that there is no remaining water, and the remaining amount until the set water level is poured.On the other hand, if it is above, it is determined that there is remaining water, and the calorific value calculation processing of the remaining water including the above-mentioned test amount of pouring is performed. Do.
In the calorific value calculation process of the residual water amount, the residual water amount in the bathtub is calculated from the integrated heating amount in the forced circulation state and the temperature difference at which the temperature of the hot water in the bathtub actually rises. Then, based on the determined remaining water amount, the remaining amount until the set water level is reached is poured.

[0004]

However, the circulation adapter may be installed at a different installation position (bottom position) with respect to the bathtub 100 as shown in FIG. In the case of the above, if the above-described conventional control method of the bath system is applied as it is, the following inconvenience occurs. In other words, when the circulation adapter 11 is installed on the bottom of the bathtub 100, the water level in the bathtub is always higher than that of the circulation adapter 11 even if there is no residual water by simply pouring the first test amount. Become. For this reason, if the controller 5 'performs the circulation determination processing, a circulating flow is generated, so that it is determined that there is residual water even though there is actually no residual water. As a result, additional heating is performed on the very small amount of hot and cold water. For this reason, the bath kettle 2 with the water heater equipped with the controller 5 'for realizing the above-mentioned conventional bath system control method.
00 'cannot be connected to the bathtub 100 on which the circulation adapter 11 is installed as described above. Such an inconvenience may also be caused by a difference in the type of the circulation adapter and the like.

[0005] On the other hand, even if the structure itself is the same bath kettle, two types of bath kettles equipped with controllers having different control methods depending on whether the circulation adapter is installed on the side or on the bottom are manufactured separately and stocked. If it is kept, it will be complicated because it looks the same.

The present invention has been made in view of such circumstances, and an object thereof is to provide the same irrespective of the installation position and the type of the circulation adapter regardless of whether the circulation adapter is installed on the side or on the bottom. It is an object of the present invention to provide a bath system control method capable of constructing and constructing a bath system using a heat source device or the like incorporating a controller.

[0007]

In order to achieve the above object, according to the present invention, a bathtub in which a circulation adapter is installed and a controlled device operated and controlled by a controller are connected via the circulation adapter. The following specific items are provided for the control method of the bath system.
That is, a plurality of different control programs are stored in advance in the controller in accordance with the type of the circulation adapter or the difference in the installation position. Then, at the time of the construction of the bath system, a specific control program corresponding to the type or installation position of the circulation adapter actually installed in the bathtub is selected from the plurality of control programs, and the specific control program is selected. Basically, the switching setting of the control program is performed so that the operation control by the controller is executed in accordance with the control program (claim 1). Here, "when the bath system is constructed" means that after the specifications of the actual bath system are determined,
This includes the period before construction, during construction, and after construction, from the start of construction to the completion of construction and actual use.

According to the first aspect of the present invention, a plurality of control programs different from each other are stored and stored in advance in the controller according to the assumed type of the circulation adapter or the difference in the installation position. Since the control program executed by the controller can be selected and switched according to the actual type or installation position of the circulation adapter, the specifications of the bath system to be installed (the type or installation position of the circulation adapter) are not determined. However, the controlled devices equipped with the same controller can be applied in common.

In order to further embody the above-mentioned claim 1 in particular based on the difference in the installation position of the circulation adapter, the following may be performed. That is, in the storage unit of the controller, at least two types of control programs, a side installation program and a bottom installation program, are stored and stored in advance in accordance with the difference in the installation position of the circulation adapter with respect to the bathtub, and when the bath system is constructed. Then, the controller receives the output of the adapter information relating to the actual installation position of the circulating adapter, and based on the adapter information, performs each process of selecting a specific control program from the two types of control programs and setting the switching. (Claim 2).
In this case, based on the output adapter information, it is determined whether the actual installation position of the circulation adapter is the side installation or the bottom installation, and a specific control program corresponding to the actual installation position is determined. The switching setting is executed by the controller.

The switching of the control program based on the adapter information in claim 2 may be performed by manual switching based on the input of adapter information by a manual operation of a constructor or the like as described later. Performing the determination processing enables automatic switching. In other words, if the controlled device is a heat source unit that is connected to the circulation adapter by a circulation pipe having a circulation pump and is capable of reheating the water in the bathtub and enabling circulation heating, the controller includes a circulation adapter after the construction of the bath system. An adapter determination process for determining the actual installation position of the adapter and outputting the adapter information is performed. Then, as a determination of the installation position in this adapter determination process, if a circulating flow through the circulating pipe is generated by operating the circulating pump in a state where a predetermined amount of hot water is injected into the bathtub, the circulating adapter is installed on the bottom surface. On the other hand, if there is no circulating flow, it is determined that side installation is provided (claim 3). In other words, if the circulation determination process is performed with a predetermined amount of hot water being poured into the bathtub such that the water surface comes below the installation position of the circulation adapter installed on the side, the circulation adapter will be circulated in the circulation pipe if the adapter is installed on the bottom. While the flow is generated, the circulation flow does not occur if the circulation adapter is installed on the side, so that it is possible to reliably determine whether the circulation adapter is installed on the bottom or on the side. The hot and cold water to be injected may be hot water or water.

In the adapter determination process according to the third aspect of the present invention, the bathtub should be empty before the injection of a predetermined amount of hot and cold water. Even if water is present, by adding the following process, erroneous determination can be prevented regardless of the presence or absence of residual water, and the installation position of the circulation adapter can be reliably determined. That is, as a determination of the installation position in the adapter determination process, even when a circulating flow is generated by the operation of the circulating pump, additional heating is performed by a heat source device, and the integrated heating amount and the temperature of hot water in the bathtub are increased. The amount of hot water in the bathtub is calculated based on the above formula, and if the calculated hot water amount is greater than the amount of hot water injected into the bathtub, the circulation adapter is determined to be installed on the side (claim 4).

On the other hand, in order to further embody the above-mentioned claim 1 in particular based on the difference in the type of the circulation adapter, the following may be performed. That is, for the storage unit of the controller,
An integrated adapter with an automatic drain plug that is independently controlled to open and close in response to a normal adapter program and switch operation depending on the type of circulation adapter installed on the bottom of the bathtub and the circulation adapter At least two types of control programs are stored and stored in advance. Then, when the bath system is constructed, the controller receives the output of the adapter information relating to the actual type of the circulating adapter in the controller and selects a specific control program from the two types of control programs based on the adapter information. Each processing for switching setting is performed (claim 5). In this case, based on the output adapter information, it is determined whether the type of the actual circulation adapter is the normal type or the type integrated with the automatic drain plug, and the specific control adapter corresponding to the actual type is used. The setting for switching to the program is executed by the controller.

The switching of the control program based on the adapter information according to claim 5 or 2 can be performed by manual switching based on input of adapter information by a manual operation of a constructor or the like. . That is, input setting means for manually inputting and setting adapter information relating to the type or installation position of the circulation adapter is provided, and the controller receives the output of the adapter information from the input setting means and selects and switches the control program. Each processing for setting is performed (claim 6). As the "input setting means", a dip switch attached to a controller or a remote controller (remote controller) connected to the controller is assigned for inputting adapter information, or an input menu for adapter information is additionally set to the remote controller. You can do it. In the case of this claim 6, if the installer who constructed the bath system confirms the actual type or installation position of the circulating adapter at the construction site, and then performs the input setting of the adapter information by the input setting means, a specific The switching setting to the control program is reliably performed.

In order to perform the switching setting of the control program according to claim 5 by automatic switching, the following may be performed. That is, the integrated automatic drain cock is connected to the controller so as to be able to output adapter information for identifying its own type to the controller and open / close information regarding the open / close state, and the adapter information output by the controller in connection with the integrated automatic drain cock. In response to this, each processing of selecting a control program and setting switching is performed (claim 7). In this case, since the integrated automatic drain plug is connected to the controller, the adapter information is output from the integrated automatic drain plug to the controller. Based on the output adapter information, a specific control program is automatically processed. Is set by switching.

Further, the integrated adapter program stored in claim 5 includes a residual water detecting process for detecting the presence or absence of residual water in the bathtub based on opening / closing information output from the integrated automatic drain cock. (Claim 8). By doing so, when the actually installed circulation adapter is integrated with the automatic drainage plug,
Since it is possible for the controller to determine whether the automatic drain cock is opened or closed based on the open / close state output from the automatic drain cock, if it is in the open state, it is possible to reliably detect that there is no residual water in the bathtub. . If it is detected that there is no remaining water, the amount of hot water up to the set water level can be dropped into the bathtub at a stretch at the time of hot water filling control. become.

The controlled apparatus according to any one of the first, second, and fifth aspects includes a circulating pipe having a circulating pump, which is connected to a circulating adapter to control the pouring of water into the bathtub and the hot water in the bathtub. By using a bathtub with a water heater that performs reheating control of the water heater (Claim 9), a bathtub with a water heater of the same specification can be used as a common heat source device regardless of the type or installation position of the circulation adapter. Then, the bath system can be constructed.

The controlled device according to any one of claims 1, 2 and 5, wherein the pouring control for pouring hot water in the bathtub into the washing machine is performed. By doing so (claim 10), as in the above case, regardless of the type or installation position of the circulation adapter,
A bath system can be constructed by applying a washing machine pouring device of the same specification as a common optional device. In particular, in the case where the circulation adapter is provided on the bottom surface, all the hot and cold water in the bathtub can be used as hot water for pouring into the washing machine.

[0018]

As described above, according to the control method of the bath system of the present invention, even if the type or position of the circulating adapter installed in the bathtub is undetermined or unspecified, the bath system can be used. Controlled devices equipped with the same controller can be applied in common, and it is possible to eliminate the need to manufacture and stock a plurality of types of controlled devices depending on the type of circulation adapter or the difference in installation position.

In particular, according to the second aspect, it is determined whether the actual installation position of the circulation adapter is the side installation or the bottom installation based on the output adapter information, and the identification corresponding to the actual installation position is made. The switching setting to the control program can be executed by the controller.

According to the third aspect, the switching of the control program based on the adapter information can be performed by the automatic switching process based on the determination of the installation position of the circulation adapter by the adapter determination process. According to the fourth aspect, in the adapter determination processing of the third aspect, erroneous determination can be prevented regardless of the presence or absence of residual water, and the installation position of the circulation adapter can be reliably determined.

According to the fifth aspect, it is determined whether the type of the actual circulation adapter is the normal type or the type integrated with the automatic drainage plug based on the output adapter information, and the type of the circulation adapter is determined according to the actual type. The switching setting to the specified control program can be executed by the controller.

According to the sixth aspect, the switching of the control program based on the adapter information according to the fifth or second aspect is input by a constructor or the like who has confirmed the actual type or installation position of the circulation adapter at the construction site. It can be reliably performed by manual switching using the setting means.

According to the seventh aspect, the switching setting of the control program according to the fifth aspect can be performed by automatic processing based on adapter information output by connection between the integrated automatic drain plug and the controller.

According to the eighth aspect, when the actually installed circulation adapter is an integral type with the automatic drain plug, the residual water detection processing is easily performed based on the open / closed state output from the automatic drain plug. When there is no residual water in the bathtub, it is possible to simplify the filling control and realize quick filling.

According to the ninth aspect, regardless of the type of the circulation adapter or the installation position, a bath system with a water heater of the same specification can be applied as a common heat source device to perform a bath system. According to the tenth aspect, a bath system can be constructed by applying a washing machine pouring device having the same specifications as a common optional device regardless of the type or installation position of the circulation adapter.

The hot and cold water in the bathtub 1 returned to the reheating heat exchanger 34 by the operation of the circulation pump 33 from 2 is heated by the combustion heat of the reheating combustion burner 35 as a reheating heating unit, and the heated hot water is transferred to the outflow pipe. The water is supplied again into the bathtub 1 through the passage 36 to reheat and circulate the heat. In the return line 32, a water level sensor 37 for detecting the water level of the bathtub 1 by detecting water pressure, the circulation pump 33, and a flap opened by passage of the circulation flow to determine the circulation in order from the upstream side in the circulation direction of the circulation hot water. Are provided, and a bath water temperature sensor 39 for detecting the temperature of the circulating water flowing into the reheating-side heat exchanger 34 is provided. In addition, an additional hot water temperature sensor 40 for detecting the temperature of the circulating hot water after heating is provided in the outgoing pipeline 36.

The pouring circuit 4 has an upstream end branched from the downstream side of the tapping line 24, branches into two on the way, and has one downstream end connected to the return line 32 on the discharge side of the circulation pump 33. And a second pouring line 42 having the other downstream end communicating with the outgoing line 36.
The pouring water from the hot water supply circuit 2 is fed through the pouring lines 41 and 42 to return the return line 32 of the circulation circuit 3.
The hot water can be poured into the bathtub 100 by flowing into both the outlet pipe 36 and the outflow pipe 36. A pouring amount sensor 43 for detecting a pouring flow rate is interposed at the upstream end position of the pouring circuit 4, and a pouring solenoid valve for switching the pouring by opening and closing control in each of the pouring lines 41 and 42. 44 and 45 are disposed, and two-stage check valves 46 and 47 are disposed downstream of the pouring solenoid valves 44 and 45.

Fuel gas is supplied to each of the hot water supply side combustion burner 23 and the additional heating side combustion burner 36 via the valve 65.

Next, the circulation adapter 12 integrated with the automatic drain plug 13 (integrated with the automatic drain plug) installed in the case of the bath system shown in FIG. 3 will be briefly described. The circulation adapter 12 is attached so as to penetrate the bottom wall 101 of the bathtub 100. The drainage plug 13 is supported so as to be movable in the vertical direction, and a water absorption hole 121, a water discharge hole 122, and a drainage hole 123 are formed therein. It was formed. The drain plug 13
Is composed of a plug 131 and a shaft 132, and the shaft 132 is guided and supported movably in the vertical direction at the center position of the circulation adapter 12. One end of the water absorption hole 12 is opened in the bathtub 100 through the drain plug 13, and the other end is connected to a return pipe 32. The spout 12
2 has one end penetrating the drain plug 13 and opening into the bathtub 100, and the other end is connected to the going pipe 36. Further, the drain hole 123 is formed in a donut shape at a position on the outer peripheral side of the circulation adapter 12, and one end thereof is formed in the bathtub 100.
And the other end thereof is connected to the drain pipe 124 in communication. When the drain plug 13 moves upward, one end of the drain hole 123 is communicated with the inside of the bathtub 100 to be opened (see the dashed line in FIG. 5), while the drain plug 13 is opened.
Is moved downward, so that one end of the drain hole 123 is closed (see the solid line in FIG. 5).

The reciprocal conversion between the open state and the closed state of the drain plug 13 is performed by pushing and pulling an operating wire 14 connected to a shaft 132. The operating wire 14 is driven by a driving unit 15 shown in FIG. As a result, the inside of the guide tube 141 is slid and pushed and pulled. The driving unit 15 is supported by the flange 102 of the bathtub 100 and includes, for example, a driving motor 15 configured by a stepping motor.
1, a shaft 152 that is rotated forward and backward by the drive motor 151, and a shaft 153 that moves forward and backward by converting the rotational force of the shaft 152 into advance and retreat force. The operating wire 14 is connected to the tip of the shaft 153 via a coupling 154.

The operation of the drive unit 15 is controlled by an automatic drain plug controller 16. The automatic drain plug controller 16 receives an operation signal of an open / close switch 161 disposed on the upper surface of the flange 102 and receives the drive signal from the drive motor 151.
Is rotated by a predetermined amount required for the opening / closing conversion of the drain plug 13. The amount of forward / backward movement of the operation wire 14 based on this rotation operation is, for example, a magnetic position sensor 162.
The automatic drain plug controller 16 receives the detection signal and detects whether the drain plug 13 is open or closed. When the automatic drain plug controller 16 is connected to the controller 5 of the bathtub 200 with a water heater by a connection terminal or the like,
The controller 5 has its own identification information, that is,
While outputting the adapter information indicating that the circulation adapter 12 is an automatic drain plug integrated type, information on the open / close state of the drain plug 13 based on the position sensor 162 is output.

In the above-mentioned bath kettle 200 with water heater, various controls such as hot water supply control, bath operation control including hot water filling control and reheating control are output from a remote controller 50 or the like by a controller 5 having an MPU and a memory. And the output from the various sensors described above.

Select and switch to the bath operation control unit 51 (setting)
And a switching processor 55 for performing the switching.

In the storage unit 53, for example, a normal type circulation adapter 11 is provided as a possible bath system.
0 for side installation type (see solid lines in FIGS. 1 and 4),
The normal type circulation adapter 11 is installed on the bottom of the bathtub 100 (see dashed lines in FIGS. 2 and 4), and the integrated circulation adapter 12 is installed on the bottom of the bathtub 100 (see FIGS. 3 and 5). ), Three control programs corresponding to each of the three types are stored and stored. That is, the side installation program 5
31, a normal bottom installation program 532, and an integrated bottom installation program 533 are stored. The storage unit 53 may be formed of, for example, an EEPROM, and a process of rewriting the storage content stored in the EEPROM into a selected specific control program may be performed as the switching setting process by the switching processing unit 55. . In this case, thereafter, the operation of the bath kettle 200 with the water heater is controlled by the cooperation of the bath operation control unit 51 and the storage unit 53.

Various processing methods can be adopted as the adapter determination processing by the adapter determination processing section 54 and the switching processing by the switching processing section 55. The following processing methods may be used in combination of one or two or more in accordance with an assumed bath system. In the present embodiment, processing based on all the following processing methods is executed.

The first processing method is performed based on adapter information manually input by a constructor or the like using a remote controller 50 or the like as adapter information input setting means, and is based on manual switching of a control program. is there. That is, when the installer or the like operates a dip switch (input setting means) for inputting adapter information preset to the remote controller 50 or the controller 5, the actual type and installation position of the circulation adapter 11 or 12 are set. Input and set adapter information for

More specifically, as shown in FIG.
The adapter information input and set to 0 is fetched (step SA1), and it is determined whether or not the adapter information is the bottom-side installation and the normal type (step SA2). The program 532 (see FIG. 7) is selected and set up, and if it is an integrated bottom installation, the integrated bottom installation program 533 is selected and set up (step SA3). Conversely, if the result of determination in step SA2 is side installation, the side installation program 531 is selected and set up (step SA4).

In the first processing method described above, if there is no output of adapter information from the remote controller 50 in step SA1, each processing in step SA2 and subsequent steps is omitted, and the second or third processing method described later is used. The processing is executed.

In the second processing method, the control program is automatically switched based on the output of the identification information from the automatic drain plug controller 16. That is, when the automatic drain plug 13 is installed in the bathtub 100, the automatic drain plug controller 16 is connected to the controller 5, and the identification information (adapter information) is output from the automatic drain plug controller 16. Therefore, this is used.

In this case, when the installer connects the automatic drain cock controller 16 to the controller 5 as shown in FIG. 9, identification information is output from the automatic drain cock controller 16 (step SB1), and the identification information of the identification information is output. If the discrimination result is the integrated bottom installation type, the integrated bottom installation program 533 (see FIG. 7) is selected and set up.
If the result of the determination is bottom installation but a single automatic drain plug, it is determined that the normal circulation adapter 11 is installed independently of the automatic drain plug, and the normal bottom installation program 532 is executed. Select and set up (YES in step SB2, step SB3). Conversely, if the result of the determination in step SB2 is not the bottom installation, it is determined that although the single automatic drain cock is installed on the bottom, the normal circulation adapter 11 is installed on the side, and the side installation program is executed. 531 is selected and set up (YES in step SB2, step SB4).

It should be noted that the above-described second processing method uses the automatic drain plug 13 if the identification information is not output in step SB1.
Is not installed, the processes after step SB2 are omitted, and the processes according to the third processing method described later are executed.

The third processing method is to perform adapter determination processing by pouring a predetermined amount of molten metal for determination and to automatically switch control programs.

That is, as shown in FIG. 10, a predetermined amount (for example, 10 L) of hot water is poured into bathtub 100 (step SC1). The hot water is supplied from the hot water supply circuit 2 (see FIG. 4) through the hot water supply circuit 4 and the circulation pipe 300 to the bathtub 1.
00. In addition, this pouring is performed by a predetermined amount (see FIG. 1) lower than the opening of the circulation adapter 11 on the side of the bathtub 100 in the case of side installation. Next, the circulating pump 33 is operated and the water flow switch 3 is turned on.
8 determines whether or not an ON signal (with a circulating flow) is output (step SC2). When the ON signal is output, the circulation adapter 11 is poured by pouring the predetermined amount of molten metal.
Is submerged, that is, it is determined that the circulation adapter 11 is installed on the bottom surface, and the normal bottom installation program 53 is used.
2 (see FIG. 7) and set up (YES in step SC2, step SC3). Conversely, if the ON signal from the water flow switch 38 is not output (no circulating flow), it is determined that the circulating adapter 11 is not submerged with the above-described predetermined amount of pouring, that is, it is determined that the circulating adapter 11 is installed on the side. Select and set up the normal side installation program 531 (NO in step SC2, step S2).

In order to perform the above-mentioned third processing method more accurately, additional processing may be further performed in the above-mentioned steps SC1 to SC4. Thus, even if residual water is present in the bathtub 100, erroneous determination can be prevented and accurate adapter determination processing and control program switching setting processing can be performed.

That is, as shown in FIG. 11, the predetermined amount of molten metal is poured and circulation is determined in the same manner as in steps SC1 and SC2 (steps SD1 and SD2). In addition, the combustion burner 35 is operated to burn the water in the bathtub 100 to the set temperature (step SD3). This reheating is stopped when the temperature detected by the bath water temperature sensor 39 reaches the set temperature. Then, the amount of hot and cold water in the bathtub 100 is calculated (calorific value calculation process) based on the integrated heating amount by the reheating and the temperature difference (increased temperature) of the detected temperature from before the reheating to after the reheating. If the calculated amount of hot water is less than the prescribed amount of hot water (for example, the above-mentioned predetermined amount of pouring water + the amount of hot water in consideration of the calorific value calculation error), the circulation adapter 11 is determined to be installed on the bottom surface, and the normal type bottom surface installation program 532 is used.
(See FIG. 7) and set up (Step S)
YES at D4, step SD5). Conversely, if the calculated amount of hot water is equal to or greater than the prescribed amount of hot water, it is determined that the circulation adapter 11 is installed on the side and that there is already residual water in the bathtub 100 before the pouring of step SD1. The side installation program 531 is selected and set up (NO in step SD4, step SD6). In the case where the automatic test run process is also performed, in step SD6, the display unit of the remote controller 50 may be combined with a display process indicating that there is a setting error when performing the bath automatic test run.

On the other hand, if the ON signal is not output from the water flow switch 38 in step SD2, an additional pouring (for example, 60-liter pouring) is dropped into the bathtub 100 just in case (step SD7), and the circulation judgment is performed again. Perform (Step S
D8). If an ON signal is output from the water flow switch 38 in this circulation determination, the normal type side installation program 531
And set it up (YE in step SD8).
S, step SD10). An additional pouring (for example, pouring of 10 L) may be performed before the set-up (step SD9), and the water flow switch 38 may be used in the circulation determination in step SD8.
If the ON signal is not output from, the circulation determination in step SD8 may be repeated after additional pouring (for example, pouring of 20 L) (NO in step SD8, step SD
11).

With the above-described processing, a specific control program corresponding to the type and location of the circulation adapter 11 or 12 actually installed in the bath operation control unit 51 is set up, and based on the specific control program. The operation control of the bath kettle 200 with the water heater will be performed.

When an integrated bottom installation program is set up as the specific control program,
In the residual water amount detection process in the hot water filling control, if the automatic drain plug 13 is in the open state or the continuous open state for a predetermined time according to the opening / closing information output from the automatic drain plug controller 16, there is no residual water in the bathtub 100. Can be grasped immediately. Thereby, the pouring of the primary dropping amount and the calculation of the residual water amount by the calorific value calculation in the residual water amount detection processing can be omitted, and the pouring of the entire hot water amount up to the set water level can be immediately dropped into the bathtub 100.
In addition, even when the automatic drain plug 13 is in the closed state and there is residual water, since the circulation adapter 12 is installed on the bottom surface and is submerged, the water level of the residual water is immediately detected by the water level sensor 37 of the pressure detection type. It can be detected, and the amount of hot water different from the set water level can be dropped into the bathtub 100 at a stretch. As described above, filling up to the set water level by the filling control can be performed quickly.

<Other Embodiments> The present invention is not limited to the above-described embodiments, but includes various other embodiments.

(Part 1) In the above embodiment, the remote controller 5
0 is used as the input setting means.
0a (see FIG. 3), the kitchen remote controller 50a may be used as input setting means.

(Part 2) In the above embodiment, the bath kettle 200 with a water heater is applied as a controlled device. However, the present invention is not limited to this. For example, a washing machine pouring device 1 as shown in FIG.
7 may be applied as a controlled device to construct a bath system. FIG. 12 shows a case where the circulation adapter 12 integrated with the automatic drainage plug is installed on the bottom wall of the bathtub 100, but the ordinary circulation adapter 11 installed on the bottom surface or the circulation adapter 11 installed on the side surface is provided. It can be applied when

The washing machine pouring device 17 includes a remote controller 18
The operation is controlled by the controller 18 connected to 1, 50 or 50a, and is interposed in the middle of the outgoing line 36 of the circulation pipe 300 at the time of construction of the bath system according to the user's request. That is, the upstream end of the washing machine pouring pipe 171 is connected to the outgoing line 36 via the three-way switching valve 172, and the downstream end is detachably connected to the washing machine 19 via the filter 173 and the water flow switch 174. It is supposed to be. In addition, the washing machine pouring pipe 1 branches off from each of the water supply pipe 21 and the hot water pipe 24 of the hot water supply circuit 2.
Aqueduct 1 that merges with 71 via a solenoid valve or check valve
75 and a hot water pipe 176 are provided so that when there is no remaining water in the bathtub 100 or when there is little remaining water, water can be injected or poured in a supplementary manner. And the controller 1
8 controls the three-way switching valve 172 to switch the upstream side (the heat exchanger 34 side) of the going pipe 36 to the washing machine pouring pipe 171 and to operate the circulation pump 33 in this state. The remaining hot water in the bathtub 100 is poured into the washing machine 19 through the return pipe 32, the upstream side of the going pipe 36, and the washing machine pouring pipe 171. Also in this case, the controller 18 may be provided with the initial setting control unit 52 in the above-described embodiment.

In this case, the plurality of control programs stored in advance in the storage unit of the controller 18 include:
For example, it may have the following processing contents. The side installation program, the normal bottom installation program, and the integrated bottom installation program are each a washing machine 1
9 and two types of control modes, a backwash mode for cleaning the filter 173. These control modes are different depending on the type of the circulation adapter and the difference in the installation position.

In the pouring mode, in both the normal type and the integrated type bottom setting programs, the entire remaining water amount can be used for pouring irrespective of the remaining water amount in the bathtub 100 because of the bottom setting. Since the total remaining water amount can be obtained by water level detection information from a water level sensor (not shown) provided in the circulation pipe 300, first, the remote controller 181,
For 50, 50a, information on how much the current remaining water is, asking whether the desired pouring amount is all or the desired amount,
And, the remaining water at the current temperature or the desired pouring temperature displays several questions, thereby giving the user an opportunity to make a selection. Next, if the operation information input by the user for the pouring amount or the like includes the input of the desired temperature and the temperature is higher than the current temperature, the operation goes through the three-way switching valve 172 and the upstream and downstream of the pipe line 36 communicates. Keep circulation pump 33
Operate. Then, additional heating is performed by the combustion burner 35 until the residual water in the bathtub 100 rises to the above-mentioned desired temperature based on the detected value of the current temperature detected by a bath water temperature sensor not shown. When the desired temperature is reached, the additional heating is stopped, and the three-way switching valve 172 is switched so that the upstream side of the outgoing line 36 and the washing machine pouring pipe 171 communicate with each other.
By this, the remaining water in the bathtub 100 is poured into the washing machine 19 until the water level in the bathtub corresponds to the pouring amount input by the user.

On the other hand, when the circulation adapter is installed on the side, even if the amount of residual water in the bathtub 100 is sufficient, the molten water is poured into the washing machine 19 with the remaining water portion higher than the side installation position of the circulation adapter. If the remaining water level is lower than the position of the side surface of the circulation adapter, the remaining water cannot be used for the pouring and the water level cannot be detected. For this reason, in the pouring mode in the side-installation program, only the information as to whether or not the washing machine can be poured and the amount that can be poured are based on the relationship between the water level detection information by the water level sensor and the side-installation position. Is displayed on the remote controller 181, 50, or 50a only, to prompt the user to input an intention to execute. When the user performs an input operation related to the pouring operation, the three-way switching valve 172 is switched to connect the upstream side of the going pipe 36 to the washing machine pouring pipe 171, and the remaining water in the bathtub 100 is circulated by the circulation pump 33. Hot water is poured into the washing machine 19 to a water level that can be sucked from the bathtub 100 by the installed circulation adapter.

On the other hand, in the backwash mode, when a backwash operation command is input as a common control irrespective of the installation position and type of the circulation adapter, the three-way switching valve 172 is controlled to switch to the filter 173 side. By communicating with the downstream side of the pipe 36 and in this state, the solenoid valve of the water guide pipe 175 is opened to inject water into the filter 173 and to pass the washed sewage that has passed through the filter 173 to the downstream side of the pipe 36. The water is poured into the bathtub 100 and drained from the drain plug of the bathtub. Before performing such common control, if the drainage plug is not in the open state when the circulating adapter is installed on the bottom surface, the wastewater will stay in the outflow pipe 36, and the control for countermeasures will be taken. Is performed. That is, in the backwash mode of the bottom installation program in the case where the normal circulation adapter is installed on the bottom of the bathtub 100, when the backwash mode is selected by the user, the remote controller 181, 50 or 50a
, An instruction of “Please open drain plug” is displayed, and then a backwash operation command from the user is received. In the backwash mode of the bottom installation program when the integrated circulation adapter 12 is installed on the bottom, information from the open / close switch operation 161 or the position sensor 162 is transmitted via the automatic drainage controller 16 (see FIG. 7). If the automatic drain plug is not in the open state, the execution of the reverse cleaning by the common control is prohibited, while if the automatic drain plug is in the open state, the common control is immediately executed.

On the other hand, when the circulation adapter is installed on the side, even if the drain plug is not in the open state, the outgoing pipe 3
Since the sewage from No. 6 only accumulates in the bathtub 100 below the position where the circulation adapter is placed on the side, backwashing can be performed regardless of whether the drain cock is opened or closed as described above.
For this reason, in the backwash mode of the side surface installation program, upon receiving a backwash operation command from the user, the common control is executed.

(Part 3) In the above embodiment, a case has been described where a plurality of control programs for each type and installation position of the circulation adapter 11 or 12 are stored in the controller 5 in advance. However, the present invention is not limited to this. When the operation control of the device is realized by a control circuit, a plurality of control circuits different from each other are provided in advance for the controller 5 or 18 according to the type of the circulation adapter or the difference in the installation position, and the construction of the bath system is performed. At this time, from among the plurality of control circuits, a specific control circuit corresponding to the type or installation position of the circulation adapter actually installed in the bathtub is selected, and the operation control by the controller is executed by this specific control circuit. The selection switching setting of the control circuit may be performed in such a manner.
