Embodiments of the present invention will be described below with reference to the drawings. 1 is a configuration diagram showing an embodiment of a bath apparatus according to the present invention, FIG. 2 is a control block diagram showing an example of a bath control unit of the bath apparatus shown in FIG. 1, and FIG. 3 is a flowchart showing an example of a trial run control program. is there.

The bath apparatus 1 according to the present invention has a bathtub 2 as shown in FIG. 1, and a circulation port 3 is formed near the bottom of the bathtub 2. A water heater 7 is connected to the circulation port 3 via an outflow pipe 6 and a return pipe 5. The return pipe 5 is provided with a water flow switch 9 and a water level sensor 10, and the water heater 7 is provided with a test operation switch 12. Further, a bath remote controller 13 is installed near the bathtub 2.

A microcomputer 21 is incorporated in the water heater 7, and the water flow switch 9, 9 is provided on the input side of the microcomputer 21 as shown in FIG.
The water level sensor 10 and the test operation switch 12 are connected. Furthermore, in the microcomputer 21,
A water level setting unit 22 as a water level setting unit, a pouring control unit 23 as a pouring control unit, a reheating control unit 24 as a reheating control unit, and a water filling control unit 25 as a water filling control unit are connected, The bath remote controller 13 is connected via a signal line 11.

Since the bath device 1 according to the present invention has the above-mentioned structure, during normal operation of the bath device 1, hot water is poured from the water heater 7 into the bathtub 2 through the outflow pipe 6 and the circulation port 3. It is filled with water between the highest water level L1 and the lowest water level L2, and the hot water in the bathtub 2 is supplied to the water heater 7 through the circulation port 3 and the return pipe 5 to be heated, and then the forward pipe 6 And it is returned to the inside of the bathtub 2 through the circulation port 3 for additional heating.

When the trial run is performed prior to the normal run, the trial run switch 12 is turned on. Then
As described below, the microcomputer 21 controls to execute a predetermined test operation work based on the test operation control program PRG shown in FIG.

First, the microcomputer 21 outputs a test operation pouring command to the pouring control unit 23, and the pouring control unit 23 receives the command and executes the following pouring operation.

That is, in step S1 of the test operation control program PRG, hot water having a constant flow rate (for example, 100 liters for the first time and 30 liters for the second time and thereafter) is gradually supplied from the water heater 7 to the outflow pipe 6 and the circulation port. Bathtub 2 through 3
After performing the pouring operation of supplying the water to the inside, a bath circulation check (that is, a check as to whether the water level in the bathtub 2 has reached the circulation port 3) is performed in step S2 of the test operation control program PRG. For that purpose, it is judged whether the water flow switch 9 provided in the return pipe 5 is in the ON state or the OFF state. That is, if the water flow switch 9 is in the OFF state, it is determined that the water level in the bathtub 2 has not reached the circulation port 3, and if the water flow switch 9 is in the ON state, the water level in the bathtub 2 has reached the circulation port 3. To determine. As a result, while it is determined that the water level in the bathtub 2 has not reached the circulation port 3, the process returns to steps S1 and S2 of the test operation control program PRG to repeat the pouring operation and the bath circulation check.

In this way, the bathtub 2 is operated by pouring several times.
When it is determined that the water level inside has reached the circulation port 3, step S3 of the test operation control program PRG is entered, and a pouring operation of a constant flow rate (for example, 30 liters) is further performed. Then, the water level in the bathtub 2 reaches the trial operation standard water level L3 slightly above the circulation port 3.

At this time, since the amount of water poured into the bathtub 2 is the amount corresponding to the standard water level L3 for trial operation, the amount of water corresponding to the minimum water level L2 during normal operation is poured as compared with the conventional method. The amount of hot water required is small, and the time required for filling water is reduced accordingly.

When the water level in the bathtub 2 reaches the trial operation reference water level L3 in this way, the pouring operation by the pouring control section 23 is completed, and the pouring control section 23 is controlled by the microcomputer 21.
A pouring completion signal is output to.

Upon receipt of the pouring end signal, the microcomputer 21 recognizes that the current water level in the bathtub 2 matches the test operation reference water level L3, and issues a water level storage command to the water level setting section 22. Output. In response to this, the water level setting unit 22 causes the trial operation control program PRG to execute step S4.
Then, the data regarding the above-mentioned test operation reference water level L3 (the value of the water level sensor 10 corresponding to the test operation reference water level L3, the water amount, etc.) is learned and stored internally, and then a water level storage end signal is output to the microcomputer 21.

Upon receiving the water level storage end signal, the microcomputer 21 outputs a reheating command to the reheating control unit 24. In response to this, the reheating control unit 24
Starts reheating the hot water in the bathtub 2 in step S5 of the test operation control program PRG. Then, the hot and cold water in the bathtub 2 circulates between the hot water supply 7 and the return pipe 5 and the forward pipe 6, and the temperature of the hot and cold water in the bathtub 2 is detected. In step S6 of PRG, it is determined whether the temperature of the hot water in the bathtub 2 is equal to or higher than a predetermined set temperature. As a result, when it is determined that the temperature of the hot water in the bathtub 2 is lower than the set temperature, a burner (not shown) in the water heater 7 is ignited, and hot water supplied from the water heater 7 to the outflow pipe 6 is supplied. Is heated, the temperature of the hot water in the bathtub 2 rises.

At this time, the water level in the bathtub 2 matches the test operation standard water level L3, and the minimum water level L2 during normal operation is set.
Since it is much lower, the amount of hot water present in the bath 2 and in the circulation path (and thus its heat capacity) is small. Therefore, the temperature rise of the hot and cold water in the bathtub 2 is performed promptly,
Since the responsiveness at the time of temperature detection is excellent, the time required for reheating is shortened.

At this time, the water level in the bathtub 2 is determined by the circulation port 3
Since the trial operation standard water level L3, which is slightly higher, has been reached,
Even if the water level in the bathtub 2 transiently rises or falls with the reheating work, the return pipe 5 and the going pipe 6 can always be kept water-sealed, and the reheating work can be performed stably. It becomes possible.

In this way, when the temperature of the hot water in the bathtub 2 rises and reaches the set temperature, the reheating operation by the reheating control section 24 is completed, and the reheating control section 24 pours hot water to the microcomputer 21. Output the end signal.

At this point, the test operation work based on the test operation control program PRG is completed.

Further, in the second and subsequent trial runs, since the data regarding the trial run reference water level L3 is stored in the water level setting unit 22 during the above-mentioned first trial run, the trial run time can be further improved by using the data. It can be shortened.

That is, the microcomputer 21 outputs a trial run water filling command to the water fill control unit 25, and in response to this, the water fill control unit 25 refers to the data regarding the test run reference water level L3 stored in the water level setting unit 22. Then, a constant flow rate from the water heater 7 (for example, 190 liters)
The hot water is supplied to the bathtub 2 to fill it up to the test operation standard water level L3.

At this time, as in the case of the first trial run, the amount of water poured into the bathtub 2 corresponds to the trial run standard water level L3, so the water amount corresponding to the minimum flooding water level L2 during normal operation is set. Compared with the conventional method of pouring, the amount of pouring is smaller and the time required for filling water is shortened accordingly. In addition, since the amount of water to be poured is stored in the water level setting unit 22, unlike the first test run, the bath circulation check can be omitted and the test run reference water level L3 can be poured at once in a short time. As a result, it is possible to further reduce the water filling time as compared with the first trial operation.

In this way, when the water level in the bathtub 2 reaches the trial operation standard water level L3, the water filling operation by the water filling control unit 25 ends, and the water filling control unit 25 outputs a water filling end signal to the microcomputer 21.

At the time of receiving this water filling end signal, the microcomputer 21 recognizes that the current water level in the bathtub 2 matches the test operation reference water level L3, and issues a reheating command to the reheating control section 24. Output. In response to this, the reheating control unit 24 reheats the hot water in the bathtub 2 in the same procedure as in the first trial operation.

Also at this time, the water level in the bathtub 2 matches the trial operation standard water level L3, and the minimum water level L during normal operation is L.
Since the temperature is much lower than 2, the temperature of the hot water in the bathtub 2 rises quickly and the responsiveness at the time of temperature detection is excellent.
The time required for reheating is reduced. Further, at this time, the reheating work can be stably performed even if the water level in the bathtub 2 transiently rises or falls, as in the case of the first trial operation.

In this way, when the temperature of the hot water in the bathtub 2 rises and reaches a predetermined set temperature, the reheating control section 24
Then, the reheating operation is finished, and the reheating control unit 24 outputs a pouring end signal to the microcomputer 21.

At this point, the trial operation work for the second time and thereafter is completed.

As described above, in the second and subsequent trial runs, the water filling time can be shortened by using the data relating to the trial run reference water level L3 learned and stored in the first trial run as compared with the first trial run. The trial run time can be shortened accordingly.

In the above embodiment, the bath apparatus 1 which starts the trial run by turning on the trial run switch 12 provided in the water heater 7 has been described, but a switch on the bath remote controller 13 (not shown). It is also possible to eliminate the special trial run switch 12 by starting the trial run by a special operation () (double push, double push, etc.).
