Abstract

PROBLEM TO BE SOLVED: To provide a storage type water heater, in which a test operation of filling a bathtub with water can be simply carried out without a special switching operation. SOLUTION: Even if a water-filling temperature sensor 43B indicates temperature lower than a prescribed temperature (step S3) during a water-filling operation, if a time elapsed from power-on counted by a timer 91 stored in a memory 95 is shorter than a prescribed time (step S4), the sensor does not sense it as abnormal (step S5). Accordingly, the test operation of filling water to the bathtub can be carried out easily by a normal operation for filling water to the bathtub.

Electric water heaters are now on sale. In this type of electric water heater, in order to prevent the hot water in the bathtub from becoming lubricious when the hot water runs out during the hot water, when the hot water is detected, the fact is notified and the hot water is stopped. Also, after the construction is completed, the contractor performs a trial run of the hot water to check the leakage of the pipes and set an appropriate hot water amount for the user, but usually even if the hot water storage tank is water before boiling. There is a type in which a remote control can be set to a test operation mode by a special switch operation using a remote control so that the hot water can be continued without detecting the running out of hot water.

The operation of the hot water beam will now be described with reference to the flowchart of FIG. 2 is a plan view of the remote controller 71, FIG. 4 is a display example of the display unit 205 during hot watering, and FIG. 5 is a display example of the display unit 205 when an abnormality is detected.

First, when the hot water switch 301 is turned on, hot water is started at the hot water temperature set by the hot water temperature setting switch 302 (step S1). At this time, the display unit 205 displays the set hot water supply temperature on the hot water supply temperature display unit 501 as shown in FIG. 4, and displays the set hot water temperature on the bath temperature display unit 502 of the display unit 205.
Is displayed. The hot water is continued until the amount set by the hot water amount setting switch 303 is heated (step S).
2) If the hot water is removed up to the set amount, the hot water is finished (step S7).

Subsequently, the hot water temperature sensor 4
When the detected temperature of 3B becomes lower than a predetermined temperature (for example, hot water setting temperature) (step S3), the elapsed time from power-on time measured by the timer 91 stored in the storage unit 95 is a predetermined time (test operation is performed). If it is less than a certain time (for example, 6 hours) (step S4), no abnormality is detected (step S5), and if it is longer than a predetermined time (step S4), abnormality is detected, and the water is not removed to the set amount. End the hot water. At this time, as shown in FIG. 5, the display unit 205 displays an error code on the bath temperature display unit 502 and a confirmation sound and a message (for example, “ping pong The hot water in the bowl has become warm. Stop the hot water beam. ”)

In step S3, when the detected temperature of the hot water temperature sensor 43B is lower than a predetermined temperature (for example, the hot water set temperature), the process proceeds to step S4. If the temperature continuously becomes lower than the predetermined temperature (for example, 10 seconds), the process may proceed to step S4. Further, the detection temperature used for the determination may be the detection temperature of the high-temperature water temperature sensor 42 instead of the detection temperature of the hot water temperature sensor 43B.

In step S4, the storage unit 95
When the elapsed time from the power-on time measured by the timer 91 stored in the power supply is less than the predetermined time, the process proceeds to step S5, but the following method may be adopted.

The first method is to provide a hot water integration unit for integrating the integrated amount of hot water from turning on the power, and the integrated hot water amount stored in the storage unit 95 is a predetermined amount (the hot water will be removed in a trial run). If the amount of hot water is less than 200 liters, the process proceeds to step S5.

The second method is provided with a hot water number counting section for counting the number of hot water from the power-on, and the number of hot water stored in the storage section 95 is a predetermined number of times (the hot water that will be hot in a test run). If it is less than the number of beams (for example, once), the process proceeds to step S5. The number of times of hot water may be counted at the start of hot water or at the end of hot water.

The third method includes a boiling number counting unit for counting the number of times of boiling of water in the hot water storage tank after the power is turned on, and the number of boiling times stored in the storage unit 95 is a predetermined number (normal hot water). If it is less than the number of times of boiling that has already been performed at the time of beaming (for example, once), step S5
To go to. The number of times of boiling may be counted at the start of boiling or at the end of boiling.

Further, any one of the above four methods, including the method described in the embodiment, may be employed alone, or two or four methods may be combined. Note that the storage unit 95 may be a non-volatile memory, and the elapsed time may be permanently stored even if a power failure occurs. Further, the contents stored in the storage unit may be reset or erased by a switch operation such as pressing the up switch and the down switch of the hot water temperature setting switch 302 simultaneously for 2 seconds or more.

As described above, after the power is turned on, when the elapsed time is less than the predetermined time, when the integrated amount of the hot water is less than the predetermined amount, when the number of the hot water is less than the predetermined number, or when the water is heated. If the number of times is less than the specified number of times, the detection of running out of water will not be detected, so even if boiling is not performed in advance, the same switch operation as a normal hot water can be performed without special switch operation, and the hot water can be removed. Since the test operation can be performed, it is easy for the contractor to understand, and the operation can be easily performed without looking at the instruction manual or the like.

If the elapsed time is stored in the non-volatile memory, the storage unit can be stored when the hot water storage type heating device is installed and used for a while, and then turned off for power outage or absence. It is possible to prevent the contents from being erased and the abnormality not being detected even when the hot water runs out when reused.

Further, when it is desired to perform a test operation of a hot water bath at the time of inspection or repair, the stored contents such as elapsed time, which is data for preventing an abnormality detection of running out of hot water by operating a switch, are reset or deleted. If you set it to the same state as when the power is initially turned on,
Even when the inside of the hot water storage tank is water, a hot water test run can be performed without detecting an abnormality of running out of hot water.

Although the present embodiment has been described in connection with the test run of a hot water bath, it is carried out when it is desired to increase the temperature of the hot water in the bathtub or when the amount of hot water in the bathtub is to be increased. Since a test run may be performed on hot water, the same hot water run-out abnormality detection control as that of the above hot water beam may be performed.

The remote controller 71 may be provided with a message display unit to display a message such as when a switch is operated. In this embodiment, the electric water heater is used. However, the present invention can be applied to a gas or oil hot water heater, or a combination of a heat pump and a solar water heater.
