<Prior art and its problems> When using a structure in which a heat exchange coil for bath heating is arranged in the hot water storage can of the water heater, when heating the bath, Even when the bath water is not circulated in the circulation circuit, that is, in the case of so-called empty heating, the heat exchange coil is not thermally damaged. Therefore, in such a structure, it is not always necessary to provide special equipment for preventing the heating of the reheating circulation circuit, for example, a circulation switch and a water level switch. However, if there is no empty heating prevention means, even if the bathtub is empty, the circulating pump will be turned on by the additional heating command from the additional heating switch, etc., and even if there is a bath temperature detection sensor, no heating signal will be output. Therefore, as a result of the circulation pump remaining in the ON state, durability of the circulation pump becomes a problem.

On the other hand, in the case of heating the hot water supply and heating the bath with a single burner, when the operation is switched from the hot water supply state to the additional heating state, the temperature control setting for the burner control is automatically performed by the additional heating command. Some are configured to be switched to a high temperature, but some are not, and some require manual operation during reheating. In the automatic switching type, defective circulation can be determined by detecting the temperature rise by the bath temperature detection sensor. If you have to manually operate, but if you try to determine the circulation failure by detecting the temperature rise by the bath temperature detection sensor, if the temperature control temperature at the time of reheating remains set low Of course, since there is no temperature rise, it is impossible to determine whether or not there is defective circulation.

<Object of the Invention> Therefore, the present invention solves the above-mentioned drawbacks of the prior art, and performs hot water supply and bath heating with a single burner, and when switching from hot water supply to additional heating, burner control is performed manually. Even in the configuration that requires temperature control, it is possible to detect defective circulation during heating, and if the temperature control is not at the temperature that can be heated during heating, change it. It is an object of the present invention to provide a bath renewal circulation monitoring device that can identify and display a defective circulation.

<Operation> If the rate of increase in bath temperature during reheating is below a certain standard rate of increase, it is tentatively determined that the bath water is not circulating well to the heat exchange can, and the timer for the fixed grace period is set. Be started. Even if the rate of increase in the bath temperature is lower than a certain reference rate of increase, the reason may be that circulation is not defective and the temperature control setting is kept at a low temperature. It is further determined whether or not the temperature control set temperature of is equal to or higher than the minimum temperature control set temperature required for additional heating. Then, by this determination, if the temperature control set temperature of the heat exchange can is lower than the minimum temperature control set temperature required for additional heating,
Since there is no circulation failure and the temperature control setting is not manually changed for the bath heating operation, a change request display of the temperature control setting is displayed. Therefore, when the user or the like changes the temperature control setting based on this change request display to obtain an appropriate temperature control set temperature, the rate of increase in bath temperature becomes equal to or higher than the reference rate of increase, and the timer of the fixed grace time is set. The operation will be canceled. If the change of the temperature control setting is not operated even when the change request is displayed or if the bath water is not circulating properly,
Since the rate of increase in bath temperature does not exceed the standard rate of increase within a certain grace period, the bath reheating operation is stopped after the lapse of the certain grace period.

When the reheating command and the circulation command are issued, the actual increase rate ΔT of the bath temperature is calculated from the bath temperature detected by the bath temperature detection sensor 33, and this increase rate ΔT is set as a reference value in advance. It is determined whether or not it is below the reference increase rate ΔT 0 (flow (c)). These are performed by a microcomputer built in the controller 40. The method of determination will be described with reference to FIG. Now, for example, the hot water supply temperature adjustment set temperature that is the minimum required to perform reheating
Assuming that the rising line of the bath temperature in the normal time at T B is B, the bath temperature difference Δ at a certain time t 1 and t 2 having the rising line B is Δ.

On the other hand, when the reheating switch is turned on and the reheating is started, the actual bathtub temperature difference ΔT at times t 1 and t 2 is calculated, and this ΔT is set as the rate of increase in bath temperature at the time of reheating,
A microcomputer compares both ΔT and ΔT 0 .
When the rate of increase ΔT is, for example, as shown by the line A in FIG. 3, ΔT exceeds ΔT 0, and therefore it is determined that the circulation by the circulation pump 32 is normally performed. On the other hand, ΔT
Is less than ΔT 0 (this is due to the fact that
This is the case where an additional heating rising line as shown by the line C in the figure is shown),
In this case, although the reheating switch is pressed, in reality the reheating is not being performed successfully, so the circulation start timer is started (flow (d)). In the above description, as the reference rate of increase ΔT 0 ,
The normal rate of increase in the hot water supply temperature control temperature T B , which is the minimum required to perform additional heating, was adopted.However, by adopting the normal temperature increase rate of the bathtub temperature at T B, heating is actually performed. It is possible to determine whether or not That is, when the bath temperature increase rate ΔT is lower than the reference increase rate ΔT 0 , it means that reheating is not actually successful. The reason why ΔT is less than ΔT 0 is that the hot water supply temperature control temperature by the hot water supply temperature control dial 52 is set higher than the hot water supply temperature control temperature T B.
ΔT is ΔT 0 due to poor circulation by the circulation pump 32.
If the temperature is lower than, and the hot water supply temperature control temperature itself is lower than the hot water supply temperature control temperature T B that is the minimum required to perform the reheating, the bath temperature increase rate ΔT is the reference increase rate even if the circulation is normal. In some cases, ΔT 0 or more cannot be achieved. Therefore ΔT <ΔT 0
In the case of, it is determined that the reheating is defective and the circulation monitoring timer is started for the time being (Flow (d)), and when a certain grace period has elapsed (Flow (to)), a reheating stop command and a circulation stop command are issued to stop the reheating. To do. Then, ΔT <ΔT 0
In the case of, it is determined whether the set hot water supply temperature control temperature is higher than the minimum required hot water supply temperature control temperature for performing additional heating (flow (e)). pump
Since the circulation by 32 is defective, the reheating is stopped after a certain period of time as described above. When the temperature falls below the above, it can be determined that the bath temperature does not rise because the set hot water temperature control temperature itself is low, and therefore the hot water temperature control change request display is displayed on the display unit 55 by a blinking signal or sound (flow (f)) ). In this case as well, since it does not change to the additional heating failure, the additional heating stop command and the circulation stop command are issued when the predetermined time has elapsed (flow (float)). When the set time of the circulation monitoring timer is adopted for a long time, it may boil before the time is up, so the boiled state is monitored (flow (h)) before the time is up.

When the temperature rise rate ΔT of the bathtub is equal to or higher than the reference rise rate ΔT 0 , it is determined that there is no defective circulation, and since reheating is being performed smoothly, the operation is continued and the bath temperature is set. When the bath temperature reaches the controlled temperature (flow (h)),
Issue a reheating stop command and a circulation stop command (flow (re)).

In the above example, the reference increase rate ΔT 0 is the increase rate at the hot water supply temperature control temperature that is the minimum required to perform reheating, but the reference increase rate ΔT 0 is the normal increase rate at each hot water supply temperature control temperature. It is also possible to adopt the rate of increase in bath temperature due to additional heating. In this case, the bath temperature increase rate during normal circulation at each hot water supply temperature control temperature is obtained in advance and stored in the microcomputer. When the reheating switch is turned on, the circulation pump is compared by comparing the reference rate of increase in the hot water supply temperature control temperature at that time with the actual rate of increase.
It is possible to judge whether the circulation by 32 is normally performed.
