The pouring device as described.

The present invention operates as follows. The filling control means (60) checks the water level in the bathtub (40) by the water level detecting means (33, 53) during the filling operation, and adjusts the subsequent pouring amount based on the confirmation. And at least two operation modes, a high-speed pouring mode for pouring without checking the water level in the bathtub (40) during the filling operation, and the operation mode selecting means (51, 81, 82). The filling operation is executed in the operation mode selected in the step (1).

For example, if the user is allowed to select through the operation mode selection means (51, 81, 82) which of the operation modes, the confirmation pouring mode and the high-speed pouring mode, should be used, the bathtub ( If the user recognizes that 40) is empty, the user normally selects the high-speed pouring mode, so that the hot water can be filled in a short time. On the other hand, if you know that there is residual water or do not know whether there is residual water,
Since the confirmation pouring mode is selected, the water can be filled to the set water level regardless of the presence or absence of residual water and the residual water amount.

The amount of hot water to be filled in the high-speed pouring mode is determined by the water level in the bathtub (40) or the amount of hot water to be poured. For example, in the case where the pouring volume when pouring in the high-speed pouring mode is determined by the pouring volume itself, such as 200 liters, the pouring control means (60) uses the flow detecting means (2).
The pouring is performed until the pouring amount detected in (6, 52) reaches the set hot water amount.

On the other hand, when determining the pouring amount in the high-speed pouring mode based on the water level, the water level pouring amount data storage means (5
The water level in the bathtub (40) stored in 4) and the bathtub (4
The pouring amount corresponding to the set water level is obtained based on the water level pouring amount data indicating the correspondence relationship with the pouring amount to 0), and the pouring amount is detected until the pouring amount detected by the flow rate detecting means (26, 52) matches. I do.

Further, the hot water setting means (83) receives from the user the designation of the hot water in the bathtub (40) upon completion of the hot water filling operation, and the hot water control means (60) at least fills the hot water in the high-speed pouring mode. The pouring amount at the time of performing the operation is changed according to the hot water amount designated through the hot water setting means (83).

For example, the water level at the time of completion of hot water filling can be selected in a plurality of stages, and the pouring amount in the high-speed pouring mode is increased or decreased according to the water level specified by the user. Thereby, even in the high-speed pouring mode, the hot water can be filled to an appropriate water level desired by the user.

Further, the water level pouring amount data correction means (7
0), every time the filling operation in the high-speed pouring mode is completed, the actual water level in the bathtub (40) is detected by the water level detecting means (33, 53), and the water level and the current pouring amount are calculated. The correspondence is compared with the correspondence between the water level indicated by the water level pouring amount data and the pouring amount, and when substantially the same difference repeatedly appears, the correspondence between the water level indicated by the water level pouring amount data and the pouring amount is detected by the water level detection. It is determined that the correspondence between the water level detected by the means (33, 53) and the pouring amount detected by the flow rate detecting means (26, 52) does not match, and the water level pouring amount data is corrected.

In this way, when the water level pouring amount data is inconsistent, it is corrected to a correct value, so that the water level when pouring is finished in the check pouring mode does not greatly differ from the set water level. .

The water level pouring amount data correcting means (70) is a means for measuring the water level pouring amount data stored in the water level pouring amount data storing means (54) when the filling operation in the high-speed pouring mode is completed. The correction is made by making a correction based on the correspondence relationship between the quantity and the pouring amount at that time. Thereby, it is not necessary to measure the water level pouring amount data which requires a long time, and the data can be easily updated.

Water level pouring amount data correction means (70)
When correcting the water level pouring amount data, the correspondence between the water level and the pouring amount is again measured again. Thereby, the water level pouring amount data can be corrected to a more accurate value.

The operation mode display means (84) displays whether or not the operation mode currently selected by the operation mode selection means (51, 81, 82) is the high-speed pouring mode. Thus, the user or the like can easily confirm in which operation mode the filling is performed.

It has become. The water level pouring amount data storage unit 54 stores the correspondence between the amount of hot water poured from the empty state into the bathtub 40 (the pouring amount) and the water pressure detected by the water level sensor (pressure sensor) 33 at each pouring amount. Memory.

FIG. 3 is a graph of the water level pouring amount data stored in the water level pouring amount data storage unit 54. In the figure, the horizontal axis represents the pouring amount Q poured into the bathtub 40,
The vertical axis indicates the water pressure P detected by the water level sensor (pressure sensor) 33. When the water level in the bathtub 40 is lower than the circulation fitting 18, the hot water in the bathtub 40 is re-fired from the circulation fitting 18 through the recirculating passage 16, and the water level sensor (pressure sensor)
3, the water level sensor (pressure sensor) 33 maintains a constant water pressure (P0) while the amount of hot water in the bathtub 40 is smaller than the amount of hot water Q0 when the water level just reaches the height of the circulation fitting 18. Is shown.

After the pouring amount exceeds Q0, the bathtub 40
The water pressure (water level) also rises as the amount of pouring water into the furnace increases. The amount of pouring Q0 until the water level exceeds the circulation fitting 18 and the inclination of the graph after the water level exceeds the circulation fitting 18 depend on the shape of the bathtub 40. For this reason, when the pouring device 10 is installed, the filling operation is performed, the pouring amount and the water pressure are measured in the process, and the correspondence between them is stored in the water level pouring amount data storage unit 54.

By subtracting the water pressure corresponding to the water level, the number of centimeters above the current water level with respect to the circulation fitting 18 is calculated. Then, the water level in the bathtub 40 is obtained by adding the previously stored height from the bottom surface of the bathtub 40 to the circulation fitting 18.

The operation mode selection section 51 is a circuit portion for selecting a procedure for performing the filling operation. The operation mode for performing the filling operation includes a confirmation pouring mode,
There are a high-speed pouring mode and a water level pouring amount data acquisition mode.

In the checking pouring mode, the pouring operation is temporarily stopped during the filling operation, the water level in the bathtub 40 is checked, and the water level difference between the water level and the set water level indicates how many more liters should be poured. The water level is obtained by referring to the water level pouring amount data stored in the water level pouring amount data storage unit 54, and thereafter, the obtained amount of hot water is poured. In the check pouring mode, even if the remaining hot water exists in the bathtub 40 at the start of the hot water filling operation, the hot water can be filled to the set water level.

In the high-speed pouring mode, a predetermined amount of hot water is poured at once without checking the water level during the filling operation. In the high-speed pouring mode, when the user
This is an operation mode suitable when it is recognized that is empty. In the water level pouring amount data acquisition mode, a small amount such as 10 liters is poured and water pressure is repeatedly detected, and data representing the correspondence between the amount of pouring water into the bathtub 40 and the water level in the bathtub 40 is obtained. Is what you do.

The pouring control section 60 includes a hot water setting section 61 for setting the pouring amount in the high-speed pouring mode, a high-speed pouring control section 62 for controlling the pouring operation in the high-speed pouring mode, and a confirmation pouring.

The data correcting section 70 includes a comparing section 71, a deviation memory 72, and a data correcting section 73. The comparing unit 71 obtains the water pressure corresponding to the actual pouring amount in the high-speed pouring mode from the water level pouring amount data stored in the water level pouring amount data storage unit 54, and determines the water pressure (planned water pressure) and the high-speed pouring. This is to compare the actual water pressure (actual water pressure) detected by the water level sensor (pressure sensor) 33 when filling is completed in the hot water mode. The deviation memory 72 is a circuit portion for storing a difference (deviation) between the planned water pressure and the actual water pressure. The data correction unit 73 has a function of correcting the water level pouring amount data stored in the water level pouring amount data storage unit 54 based on the actual water pressure.

The data correction unit 70 corrects and corrects the water level pouring amount data when the absolute value of the deviation between the actual water pressure and the expected water pressure is within a certain reference value and the deviation of the same value appears a plurality of times. It is supposed to.

The remote controller 80 includes an operation section 80a and a display section 8
0b. As shown in FIG.
As an operation unit 80a, an automatic switch 81 for instructing a filling operation in a confirmation pouring mode, a high-speed switch 82 for instructing a filling operation in a high-speed pouring mode,
A hot water amount setting switch 83 and the like for adjusting the set water level in a plurality of stages are provided. The remote controller 80 is connected to the display unit 8
0b, an operation mode display lamp 84 for notifying that the filling operation is being performed in the high-speed pouring mode;
A liquid crystal display 85 for displaying various operating states in addition to a set temperature and a water level is provided.

Next, the operation will be described. FIG. 5 shows a flow of the operation performed by the pouring device 10 when performing the filling operation. When the automatic switch 81 of the remote controller 80 is depressed and the filling operation in the confirmation pouring mode is instructed (step S)
101; Y), the filling control unit 60 checks whether or not effective water level pouring amount data is already stored in the water level pouring amount data storage unit 54 (step S102). Before instructing the start of the hot water filling operation, the user operates the hot water setting switch 83 and the like to set a desired water level and hot water temperature.

When effective water level pouring amount data is stored in the water level pouring amount data storage section 54 (step S1).
02; Y), the pouring operation in the confirmed pouring mode is executed by the confirmed pouring controller 63 (step S103).

On the other hand, when the effective water level pouring amount data is not stored (Step S102; N), the bathtub shape data obtaining operation control unit 64 is replaced with the confirmation pouring control unit 63.
Performs the pouring operation in the water level pouring amount data acquisition mode (step S110). That is, if there is no water level pouring amount data, the water level cannot be confirmed by the water pressure detected by the water level sensor (pressure sensor) 33.
The mode is forcibly switched to the water level pouring amount data acquisition mode in order to acquire the water level pouring amount data.

When the high-speed switch 82 of the remote controller 80 is pressed to instruct the filling operation in the high-speed pouring mode (step S104; Y), the filling control unit 60 is enabled in the water level pouring amount data storage unit 54. It is checked whether or not the proper water level pouring amount data is stored (step S105). If valid data is stored (step S105;
Y) The high-speed pouring control unit 62 executes the pouring operation in the high-speed pouring mode (step S108), and turns on the operation mode display lamp 84 to notify the user that the hot water is filled in the high-speed pouring mode. I do.

If effective water level pouring amount data is not stored in the water level pouring amount data storage section 54 (step S
105; N), a warning to that effect is issued by a display and a buzzer (step S106), and the user is alerted. If the user performs a special switch operation for forced execution within a predetermined time (step S107; Y), a predetermined amount of hot water, such as 180 liters, is poured in the high-speed pouring mode ( Step S108).

After the warning is issued, if the forcible execution switch operation is not performed within a predetermined time (step S1).
07; N), filling control section 60 executes the pouring operation in the water level pouring amount data acquisition mode instead of the high-speed pouring mode (step S110). That is, since the amount of hot water to be poured in the high-speed pouring mode is obtained from the water level pouring amount data stored in the water level pouring amount data storage unit 54, if valid water level pouring amount data is not registered, the forced Unless instructed to execute, the mode is switched to the water level pouring amount data acquisition mode.

When the filling operation in the water level pouring data acquisition mode is instructed by a special operation provided for the installer or the like (step S109; Y), the bathtub shape data acquisition operation control section 64 sets the water level. The pouring operation is started in the pouring amount data acquisition mode (step S110). If the water level pouring amount data is not stored when the check pouring mode is selected, the mode automatically shifts to the water level pouring amount data acquiring mode. Therefore, a special operation for executing the water level pouring amount data acquiring mode is performed. Need not necessarily be provided.

As described above, one of the operation modes of the confirmation pouring mode, the high-speed pouring mode, and the water level pouring amount data acquisition mode can be selected by various operations. The filling operation can be performed in the operation mode. For example, when there is remaining hot water in the bathtub 40 or when the user does not recognize whether or not there is remaining hot water, the user presses the automatic switch 81 to instruct the filling in the confirmation pouring mode. Will do. Thereby, the hot water can be filled to the set water level regardless of the presence or absence of residual water.

On the other hand, when recognizing that the inside of the bathtub 40 is empty, the user presses the high-speed switch 82 to instruct the filling operation in the high-speed pouring mode. As a result, it is possible to fill the water in a short time, and it is confirmed by the user that there is no residual water. Therefore, the water level can be adjusted to the set water level desired by the user without checking the water level on the pouring device 10 side. Can be stretched.

After the apparatus is installed, it is preferable to perform a filling operation in a water level pouring amount data acquisition mode by an installer, but since filling in this mode requires a long time, the filling operation is not performed. In some cases, the installer wants to confirm the operation only by checking whether the operation is normal or not. In such a case, filling is instructed in the high-speed pouring mode, and after a warning is issued, the operation is performed forcibly to complete filling in a short time without acquiring water level pouring amount data. And can meet the demands of the installer.

The flow of the filling operation in each operation mode will be described below. FIG. 6 shows the flow of the filling operation in the water level pouring amount data acquisition mode. First, the reheating pump 14 is turned on (step S201), and it is confirmed whether or not the flowing water switch 21 is turned on (step S20).
2). At this stage, if the flowing water switch 21 is turned on (step S202; Y), the water level is already set to the circulation fitting 1
8, the corresponding relationship between the water level and the pouring amount based on the position of the circulation fitting 18 cannot be measured. Therefore, the reheating pump 14 is turned off (step S203), and an error message indicating that the water level pouring amount data cannot be obtained is displayed (step S204).
The process ends.

If the water switch 21 is not turned on (step S202; N), the reheating pump 14 is temporarily turned off (step S205), and the water pressure (P0) is measured by the water level sensor (pressure sensor) 33. (Step S206). Thereafter, a predetermined small amount of hot water such as 10 liters is poured into the bathtub 40 (step S207),
The reheating pump 14 is turned on again (step S
208). At this time, if the running water switch 21 is not turned on, the water level is still lower than that of the circulation fitting 18, so the flow returns to step S205, and the water is poured into the bathtub 40 by 10 liters to check whether the running water switch 21 is turned on. The processing is repeated (steps S205, S206, S20
7, S208, S209; N).

When the flowing water switch 21 is turned on (step S209; Y), the water level in the bathtub 40 has reached or exceeded the circulating metal fitting 18, so the reheating pump 14 is turned off (step S209). S21
0) After waiting for the water pressure to stabilize, the water pressure (P1) at that time is measured by the water level sensor (pressure sensor) 33 (step S211). In addition, so far bathtub 4
The amount of hot water Q1 poured into 0 is stored. Then, after further pouring 10 liters (step S212), the water pressure (P) is again detected by the water level sensor (pressure sensor) 33.
2) is measured (step S213), and the pouring amount Q2 up to this point is stored.

Next, based on the water pressure P0, the water pressure P1, the water pressure P2, the pouring amount Q1, and the pouring amount Q2, the pouring amount Q0 at the time when the water level has just reached the height of the circulation fitting 18, and the water pressure P0 at that time. Are obtained by calculation (step S214). That is, in FIG. 3, the point (P1, Q1) and the point (P2, Q1)
2) is plotted, and a straight line 91 having a predetermined slope connecting them is drawn. A straight line 92 having a constant water pressure P0 is drawn, the intersection (P0, Q0) of these is determined, and the water pressure P0 pouring amount Q0 when the metal is poured to the circulation fitting 18 is obtained.

Then, after pouring a further 10 liters,
The operation of detecting the water pressure and registering these relationships in the water level pouring amount data storage unit 54 is repeated until the set water level is reached (Steps S215, S216, S217, S218;
N), when the set water level is reached (step S218;
Y) Terminate the filling operation. Here, whether or not the set water level has been reached is determined based on the height of the circulation fitting 18. That is, from the difference between the water pressure detected by the water level sensor (pressure sensor) 33 and the water pressure P0 at the height of the circulating bracket 18, how many centimeters above the circulating bracket 18 is located is determined, and based on this, the set water level is determined. It is determined whether or not has been reached.

When pouring into bath 40, pouring solenoid valve 32 is opened. As a result, the feed water flows into the hot water supply heat exchanger 24 through the feed water pipe 25, and when the flow sensor (flow rate sensor) 26 detects this flow, the hot water supply burner 23
Is performed. The hot water heated by the hot water supply heat exchanger 24 by receiving the heat from the hot water supply burner 23 flows into the reheating circuit 16 through the filling pipe 31 and drops into the bathtub 40 through the reheating circuit 16. It is supposed to be.

Next, the filling operation in the confirmation pouring mode will be described. FIG. 7 shows a flow of the filling operation in the confirmation pouring mode. First, it is confirmed whether or not the residual water is present up to a water level above the circulation fitting 18. That is, the reheating pump 14 is turned on (step S301), and it is determined whether or not the flowing water switch 21 is turned on (step S30).
2). If the flowing water switch 21 is not turned on (step S302; N), the water level is lower than the circulation fitting 18, or the air has entered the reheating circulation path 16 and the reheating circulation pump 14 is idle. If you are either.

Then, the reheating circulation pump 14 is once turned off (step S303), and 10 liters of water are poured to expel air in the reheating circulation path 16 (step S30).
4) The supplementary heating circulation pump 14 is turned on again (step S305), and it is checked whether or not the flowing water switch 21 is turned on (step S306). If the running water switch 21 is still not turned on at this time, it is determined that the water level is lower than the circulating metal fitting 18, and after turning off the reheating pump 14 (step S307), the hot water of the reference amount Qa is poured at once. Hot water is applied (step S308).

The reference amount Qa is such that even if the bathtub 40 is initially empty, the water level is always higher than that of the circulating metal fitting 18, and
Even if the water level reaches just in the vicinity of the circulation fitting 18 at the stage of pouring 10 liters at step S304, the hot water of the reference amount Qa is set so as not to exceed the set water level by pouring hot water. . For example, assuming that Q0 is 80 liters and the pouring amount Qf up to the set water level is 200 liters, the reference amount Qa is set to 90 liters or the like.

As shown in FIG. 4, when the bath tub 40 is initially empty, the sum of 10 liters poured for preventing the reheating pump 14 from running idle and the reference amount Qa becomes 100 liters. Exceeds Q0 (80 liters). In this case, the remaining pouring amount Qr1, which is the subsequent pouring amount,
Is determined by Qf-Qa-10, which is 100 liters in this example.

On the other hand, if there is any residual water of Qi at first, the total of 10 liters for preventing idling of the reheating pump 14 and Qi and Qa is 10 + Qi + 90, but Qi + 10 liters is always 80 liters. Therefore, at the stage when the hot water having the reference amount Qa is poured, the maximum pouring amount is 180 liters, and the set water level Qf (200
Liters). In this case, the remaining pouring amount Qr2 which is the subsequent pouring amount is (Qf-Qa-10-Q
i) liter.

After the hot water having the reference amount Qa is poured, the recirculating pump 14 is turned on (step S309), and it is checked whether or not the flowing water switch 21 is turned on (step S31).
0). Here, if the water switch 21 is not turned on (step S310; N), it is determined that the plug of the bathtub has been disconnected, and after turning off the reheating circulation pump 14 (step S311), a bathtub plug removal error occurs. Is notified (step S312).

When the flowing water switch 21 is turned on (Step S310; Y), the reheating circulating pump 14 is turned off (Step S313), and after the water pressure is stabilized, the water pressure (pressure sensor) 33 detects the water pressure (pressure sensor). (Pa or Pb in FIG. 4) is detected (step S314). Hot water quantity corresponding to the detected water pressure and hot water quantity Q corresponding to the set water level
f is obtained from the water level pouring amount data stored in the water level pouring amount data storage unit 54, and the difference in hot water amount is calculated as
The amount of hot water to be poured in the future to reach the set water level (remaining hot water amount Q
r) (step S315).

It should be noted that, from the beginning of the hot water filling, the water level is
If it is higher than 8 (step S302; Y or step S306; Y), the water pressure can be measured at this point without pouring the reference amount Qa of hot water. Therefore, the reheating pump 14 is turned off (step S3).
13) Then, the water pressure is detected by the water level sensor (pressure sensor) 33 (step S314), and based on the water pressure, a pouring amount (remaining pouring amount Qr) required to reach the set water level is obtained (step S315).

The remaining pouring amount Qr thus obtained is poured at once (step S316), and the water pressure at the end of pouring is measured (step S317). It is determined whether or not this has reached the water pressure corresponding to the set water level. Check (step S318). If the set water level has not been reached (step S318; N), the amount of the hot water shortage with respect to the set water level is calculated based on the current water pressure, and the shortage is again poured by the shortage (step S319).

If the set water level has been reached (step S318; Y), it is checked whether or not the temperature detected by the bath temperature sensor 15 is the set temperature. Is raised (step S320), a buzzer sounds at the end of the filling, and a mark indicating the completion of the filling is displayed on the liquid crystal display 85 to notify the completion of the filling (step S321). The hot water filling operation is terminated.

Next, the flow of the filling operation in the high-speed pouring mode will be described. FIG. 9 shows a flow of the filling operation in the high-speed pouring mode. First, the pouring amount corresponding to the set water level is obtained from the water level pouring amount data stored in the water level pouring amount data storage unit 54 (step S401), and the amount of hot water is poured at once (step S402).

Thereafter, the reheating pump 14 is turned on (step S403), and it is confirmed whether or not the water switch 21 is turned on (step S404). Running water switch 2
If No. 1 is not turned on (step S404; N), the reheating pump 14 is turned off (step S40).
5) Display a bathtub stopper removal error (step S40)
6) End the filling operation.

If the water switch 21 is turned on (step S404; Y), the reheating pump 14 is turned off (step S407), and the water level sensor (pressure sensor) 33 waits for the water pressure to stabilize. The water pressure (actual water pressure Pfj) at the time of completion of tensioning is detected (Step S)
408). The water pressure (planned water pressure Pf) corresponding to the amount of hot water poured during the filling operation measured by the flow sensor (flow rate sensor) 26 is referred to the water level pouring amount data stored in the water level pouring amount data storage unit 54. Ask for it.

The comparing section 71 of the data correcting section 70 compares a difference (deviation) between the actual water pressure Pfj and the expected water pressure Pf with a predetermined reference value (for example, a water pressure corresponding to a water level of 2 cm). If the absolute value of the deviation is larger than the reference value (step S409; N), the cause is not the deterioration of the water level sensor (pressure sensor) 33 or the flow sensor (flow rate sensor) 26, but residual water exists from the beginning. It is determined that it has been done. If the hot water temperature is lower than the set temperature, after the reheating is performed (step S413), the completion of the hot water filling operation is notified by a buzzer or a display (step S414).
The filling operation in the high-speed pouring mode ends.

On the other hand, when the absolute value of the deviation is smaller than the reference value (step S409; Y), it is determined whether or not the previous deviation stored in the deviation memory 72 and the present deviation are the same value. Investigation (step S410), when the same deviation appears twice consecutively (step S410; Y), the cause is deterioration of the water level sensor (pressure sensor) 33 and the flow sensor (flow rate sensor) 26, and the like. Is determined, and the water level pouring amount data stored in the water level pouring amount data storage unit 54 is corrected (step S412).

If the previous deviation does not match the current deviation, the current deviation is stored in the deviation memory 72 (step S411). Thereafter, reheating is performed to the set temperature (step S413), and the completion of the hot water filling operation is notified (step S414). As shown in FIG. 10, the water level pouring amount data is corrected by moving the entire graph in parallel so that the expected water pressure Pf corresponding to the pouring amount Qf matches the actual water pressure Pfj. By correcting the water level pouring amount data in this way, the remaining pouring amount can be correctly obtained by referring to the water level pouring amount data when pouring in the confirmation pouring mode thereafter.
It can be filled with water exactly to the set water level.

In the above-described embodiment, the high-speed switch 82 is provided to designate the high-speed pouring mode. However, the special switch is not provided, and the hot water in the high-speed pouring mode is operated by a special operation. The start of the tensioning operation may be instructed. For example, the high-speed pouring mode can be designated by pressing two switches simultaneously or pressing the automatic switch 81 twice in succession. Although the high-speed pouring mode is indicated using the operation mode display lamp 84, the operation mode may be notified by displaying predetermined marks, characters, and the like on the liquid crystal display 85.

Further, in the embodiment, the pouring amount in the high-speed pouring mode is specified by the water level, but the number of liters may be directly specified. For example, the pouring amount may be selected in a plurality of steps in units of a predetermined amount such as 20 liters such as 180 liters, 200 liters, 220 liters, and 240 liters.

Further, in the embodiment, when the water level pouring amount data is out of order, the water level pouring amount data is corrected based on the actual water pressure Pfj. However, the water level pouring amount data is measured again. You may. For example, it is stored that the data needs to be corrected, and the next time the filling operation is performed, the filling operation is performed in the water level pouring amount data acquisition mode regardless of the operation mode specified by the user. The data may be corrected. In the embodiment, the water level pouring amount data is corrected when the deviation of the same value appears twice consecutively, but may be set to three or more times.

When filling in the check pouring mode, hot water having a reference amount Qa is poured at a stroke so as to exceed the circulation fitting 18, and the water pressure (water level) is measured. After that, the pouring amount was obtained. However, the pouring was performed in small amounts, such as 10 liters, to make the water level just at the height of the circulating bracket 18, and the pouring amount up to the set water level based on the water level of the circulating bracket 18 was determined. It may be.

In this case, the fact that the water level has reached the circulating bracket 18 is detected by the flowing water switch 21, so that even if the water level sensor (pressure sensor) 33 fails, it becomes possible to pour the molten metal to almost the set water level. . In addition, since the water pressure corresponding to the circulation fitting 18 is checked every time the hot water is filled in the check pouring mode, the water level at the time of completion of the hot water filling from the set water level even if the installation conditions of the bathtub 40 and the hot water pouring device 10 are changed. There is no big deviation.

When the high-speed pouring mode is selected and valid water level pouring amount data is not stored, if the special operation of the forcible execution is not performed within a predetermined time, the mode shifts to the water level pouring amount data acquiring mode. But issued a warning,
The filling operation may be stopped. After issuing the warning, the designation of the pouring amount from the user may be received in terms of the amount of hot water (liter). It is also possible to automatically shift to the water level pouring amount data acquisition mode without issuing a warning.
