  The real-time temperature display unit 29 displays the hot water temperature in the bathtub 8 during the reheating operation in real time based on the detection signal of the bath temperature sensor 5, for example, as shown in FIG. As shown, the current bath temperature (the hot water temperature in the bathtub 8) during the reheating operation is directly digitally displayed on the display screen of the remote controller 26 in real time.

  The bathing temperature data setting storage unit 32 sets and stores input data of a bathing possible temperature range in which the temperature of hot water in the bathtub 8 becomes a bathing temperature and an optimal bathing temperature range in which the temperature of the hot water in the bathtub 8 is optimal for bathing. The bathing temperature setting button 45 of the remote control 26 is operated, and the temperature range of ± 0.5 ° C. is set with respect to the bath setting temperature set in the bath temperature setting unit 34.

And the input data such as the optimum bathing temperature range, etc., to determine whether the hot water temperature in the bathtub 8 is within the optimum bathing temperature range, the bathing possible temperature range, or the bathing not possible temperature range. When the hot water temperature in the bathtub 8 is within the optimum bathing temperature range, a bathing optimum discrimination signal is added to the temperature distinction display unit 31, and bathing is possible when the hot water temperature in the bathtub 8 is within the bathing possible temperature range. A discrimination signal is applied to the temperature distinction display unit 31, and a bathing impossibility discrimination signal is applied to the temperature distinction display unit 31 when it is within the bathing unavailable temperature range.

  The temperature distinction display unit 31 receives each discrimination signal applied from the bath temperature discrimination unit 28 and discriminates and displays the hot water temperature in the bathtub 8, and a bathing impossibility discrimination signal is added from the bath temperature discrimination unit 28.

  The PQ data memory 30 stores hot water filling characteristic data indicating the relationship between the bathtub water amount Q and the bathtub water level P as shown in FIG. The bath water level during automatic hot water filling is detected based on the data and the flow rate detected by the flow sensor 16, and automatically based on the flow rate detected by the flow sensor 16 and the hot water filling characteristic data (PQ data). The bathtub water level in the hot water filling is detected and added to the real-time water level display unit 37 and the bathtub water level determination unit 38.

  The real-time water level display unit 37 receives a bathtub water level detection signal applied from the bathtub water level detection unit 40 and directly displays the bathtub water level detected by the bathtub water level detection unit 40 in real time. The water level in the bathtub is displayed on the display screen of the remote control 26 by digital display or the like. In addition, the real-time water level display unit 37 receives the bathtub water level detection signal applied from the water level sensor 20 and displays the bathtub water level other than that during automatic hot water filling on the display screen of the remote control 26 or the like.

  The real-time water level display unit 37 has a water level display switching means (not shown). By the water level display switching means, the bathtub water level detection signal and the bathtub water level detection unit 40 applied from the water level sensor 20 are displayed. The detection signal of the bathtub water level to be added is switched, and when hot water is poured into the bathtub 8 during the filling operation, the water level in the bathtub 8 detected by the bathtub water level detection unit 40 is displayed in real time. The water level in the bathtub 8 detected by the water level sensor 20 is displayed at other times (when the hot water flow is stopped or after the hot water filling is finished).

  The bathtub water level data setting storage unit 41 sets and stores input data of a bathing water level range in which the bathtub water level becomes a bathing water level and a bathing water level range in which the bathtub water level is optimal for bathing. With respect to the bathtub water level set in the bathtub water level setting unit 36 by operating the water level setting button 46, the water level range of 90 to 100% is stored in the water level range memory 35 as the bathing optimum water level range, and the set bathtub water level is set. In contrast, a water level range of 60 to 90% is stored as a bathable water level range, and a bath water level range of less than 60% with respect to the set bath water level is stored as a bathing impossible water level range.

  The bathtub water level determination unit 38 receives the bathtub water level detection signal added from the bathtub water level detection unit 40, compares the detected bathtub water level with each water level range stored in the water level range memory 35, and When the bath water level detected by the water level detection unit 40 is in the bathing optimum water level range, it is determined that bathing is optimum, and a bathing optimum discrimination signal is added to the water level discrimination display unit 39, and the bath water level detected by the bath water level detection unit 40 is the bathing level. When it is within the possible water level range, it is determined that bathing is possible, and a bathing possibility determination signal is added to the water level distinguishing display unit 39. When the detected bath water level is within the non-bathable water level range, it is determined that bathing is not possible. It adds to the water level distinction display part 39.

  The bathtub water level discriminating unit 38 has a means for switching the water level distinction display (not shown), and the bathtub added from the water level sensor 20 when the bathtub water level discriminating unit 38 discriminates and judges the water level in the bathtub 8. The function of switching between the detection signal of the water level and the detection signal of the bathtub water level applied from the bathtub water level detection unit 40 is compared with the optimum bathing water level range and bathing water range stored in the water level range memory 35. As a result, the bathtub water level determination 38 determines the bathtub water level detected by the bathtub water level detection unit 40 as described above when hot water is poured into the bathtub 8 during automatic hot water filling. Compared with each range such as the optimum bathing water level range stored in the water level range memory 35, each discrimination signal such as a bathing optimum discrimination signal and a bathing possibility discrimination signal is added to the water level discrimination display unit 39, and thereafter So that the addition of the respective determination signals are compared with each level stored in the tub water and the water level range memory 35 detected by the water level sensor 20 in the water level distinction display section 39 when the.

  The water level discrimination display unit 39 receives each discrimination signal applied from the bathtub water level discrimination unit 38. For example, when a bathing impossibility discrimination signal is added, the water level display LED 48 of the remote control 26 is turned on, and a bathing discrimination discriminating signal is added. The water level display LED 48 blinks when the bathing is detected, and the water level display LED 48 is turned off when the bathing optimum determination signal is applied, so that the bath water level detected by the bath water level detection unit 40 and the water level sensor 20 is displayed in a distinguishable manner. is there.

  The present embodiment is configured as described above, and the bath apparatus of the present embodiment performs an automatic filling operation and a reheating operation by the same operation as the conventional bath apparatus shown in FIG. Then, the water level in the bathtub 8 is detected by the bathtub water level detection unit 40 during the automatic hot water operation and displayed on the water level display unit 42, and the temperature in the bathtub 8 is displayed by the temperature display unit 33 during the reheating operation.

  Hereinafter, based on the flowchart of FIG. 3, an operation at the time of the reheating operation of the bath device of this embodiment (reheating flow) will be described. First, when a desired bath temperature is set in the bath temperature setting unit 34 by operating the bath temperature setting button 45 of the remote controller 26, etc., based on the set temperature, the optimum bathing temperature range, bathing possible temperature range, bathing not possible Input data of the possible temperature range is stored in the temperature range memory 27. When the reheating switch is turned on at step 101, the reheating LED 47 is turned on at step 102, and the reheating circulation pump 4 is activated. Next, in step 104, it is determined whether or not 30 seconds have elapsed since the recirculation circulation pump 4 is operated. If 30 seconds have elapsed, in step 105, the bath temperature sensor 5 detects the hot water temperature in the bathtub 8 ( The bath temperature is measured, and in step 106, the real-time temperature display unit 29 displays the hot water temperature in the bathtub 8 in real time.

  In step 107, the bath temperature determination unit 28 compares the bathing optimum temperature range stored in the temperature range memory 27 with the hot water temperature in the bathtub 8 applied from the bath temperature sensor 5. When the hot water temperature is within the optimum bathing temperature range, the routine proceeds to step 114, and the reheating LED is turned off. On the other hand, when the hot water temperature within the bathtub 8 is outside the optimum bathing temperature range, the routine proceeds to step 108. In step 108, the bath temperature determination unit 28 determines whether the hot water temperature in the bathtub 8 is within the bathing possible temperature range stored in the temperature range memory 27. When the bath temperature is within the bathing possible temperature range, In step 109, the reheating LED 47 blinks and the process proceeds to step 110. When the hot water temperature in the bathtub 8 is outside the bathing possible temperature range, that is, in the bathing not possible temperature range, the process proceeds to step 110 as it is. Start driving.

  In step 111, the bath temperature determination unit 28 determines whether or not the hot water temperature in the bathtub 8 is within the optimum bathing temperature range, and the step is performed until the hot water temperature in the bathtub 8 is within the optimum bathing temperature range. The operation from step 108 to step 111 is repeated. When it is determined in step 111 that the hot water temperature in the bathtub 8 is within the optimum bathing temperature range, the reheating operation is terminated in step 112, the recirculation circulation pump 4 is stopped in step 113, and step 114. Then, the reheating LED is turned off, and in step 115, the boiling buzzer is sounded.

  In addition, by the operation from step 107 to step 111, it is determined whether the hot water temperature in the bathtub 8 is within the optimum bathing temperature range, the bathing possible temperature range, or the bathing impossible temperature range, and discriminated by the reheating LED. The real-time display of the hot water temperature in the bathtub 8 by the real-time temperature display unit 29 is continued during the period of time, and after the buzzer is turned on in step 115, the real-time temperature display is terminated in step 116.

  Next, based on the flowchart shown in FIG. 4, the operation | movement at the time of the automatic filling operation of the bath apparatus of a present Example is demonstrated. First, when a desired bath temperature is set in the bath temperature setting unit 34 by operating the bath temperature setting button 45 of the remote controller 26, etc., based on the set temperature set in the bath temperature setting unit 34, an optimal bathing temperature range, The input data of the temperature range where bathing is possible and the temperature range where bathing is not possible are stored in the temperature range memory 27, and when the desired bath water level is set in the bath water level setting unit 36 by operating the bath water level setting button 46, etc. Based on the set water level in the bathtub 8 set in the water level setting unit 36, input data of the optimum bathing water level range, the bathing possible water level range, and the non-bathing water level range is stored in the water level range memory 35.

  When the automatic operation switch is turned on in step 201 in FIG. 4, the water level display LED 48 is lit in step 102. Next, in step 203, the bathtub water level determination 38 receives the bathtub water level detection signal detected by the water level sensor 20, determines whether the bathtub water level is up to the circulation port of the circulation fitting 10, and the bathtub water level circulates. When the water level is at the mouth, the process proceeds to step 206. On the other hand, when the bath water level is not at the circulation port, the hot water is poured into the circulation port at step 204, and the water is poured until it is determined at step 205 that the bathtub water level is at the circulation port. When hot water is continued and the molten metal is poured up to the circulation port, the routine proceeds to step 206.

  Then, in Step 206, the operation from Step 101 to Step 114 of the reheating flow shown in FIG. 3 is performed. In Step 207, the water level of the bathtub is detected by the water level sensor 20, and in Step 208, the real time water level display unit is displayed. 37, the water level in the bathtub 8 is displayed in real time.

  Next, in step 209, the water level in the bathtub 8 detected by the water level sensor 20 is compared with the optimum bathing water level range stored in the water level range memory 35 by the bath water level discriminating unit 38. When the water level is within the bathing optimum water level range, the routine proceeds to step 220, where the water level display LED is turned off. When it is determined in step 209 that the water level in the bathtub 8 is outside the bathing optimum water level range, the water level in the bathtub 8 is stored in the water level range memory 35 by the bathtub water level determination unit 38 in step 210. When the water level in the bathtub 8 is within the bathable water level range, in step 211, the water level display LED 48 blinks and the process proceeds to step 212, where the water level in the bathtub 8 is determined. If the water level is outside the bathable water level range, that is, is in the non-bathable water level range, the process proceeds to step 212 while the water level range LED remains on.

  In step 212, the hot water filling characteristic data stored in the PQ data memory 30, the flow rate detected by the flow sensor 16, and the water level information detected by the water level sensor 20 by the bathtub water level detection unit 40.
