TECHNICAL FIELD The present invention relates to hot water supply control of a hot water storage type water heater.

2. Description of the Related Art As shown in FIG. 5, a conventional hot water storage type hot water heater has a hot water storage tank 1 in which a heat generating part is provided, and a temperature detecting means 6 for detecting a water supply temperature and a boiling temperature into the hot water storage tank 1. And a storage device 7 for storing the actual amount of hot water used as heat quantity data, a heat quantity setting device 8 for setting a heat quantity to be stored in the hot water tank 1 based on the data of the storage means 7, and the heat quantity. And the energization time calculation device 9 for calculating the energization time from the rated power consumption of the heat generating portion, and the energization time calculated by the energization time calculation device 9 is delayed from the midnight power supply time so as to obtain heat during the midnight power supply time. It is composed of an energization control device 10 for starting energization of parts, and a used calorie calculation device 11 for calculating the amount of heat for the amount of hot water used and inputting the value into the storage device 7 to update the data. there were.
(For example, Japanese Laid-Open Patent Publication No. 60-30938) Problems to be Solved by the Invention However, in the above-mentioned configuration, the calorific value calculation is performed only for the actual amount of hot water used per day at the midnight power supply time. In the daytime, the amount of hot water used up to now, the purpose of the amount of hot water used, the amount of hot water that can be used, the amount of hot water that can be used according to the purpose, etc. are unknown. There were problems such as running out of water.

Therefore, the present invention solves the above conventional problems,
The purpose is to discriminate the usage of the amount of hot water used from the state of tapping hot water and notify the user of the usage status for each purpose.

Means for Solving the Problems In order to achieve this object, the hot water storage type water heater of the present invention is a hot water storage tank in which a heat generating portion is provided, and a hot water discharge amount detecting means for detecting a hot water discharge amount from the hot water storage tank, A calculating means for calculating and storing the amount of discharged hot water, the length of discharged hot water, and a discharge interval from the signal from the amount of discharged hot water detecting means, and a signal from the calculating means to determine the use of the amount of used hot water, and integrate the discharged hot water amount for each use. It is provided with a judging means for storing and a notifying means for notifying the state of the amount of hot water used for each application by a signal from the judging means.

Effect The present invention detects the amount of hot water discharged by the above-described configuration, determines the use of the amount of hot water used from the amount of hot water discharged, the duration of hot water discharge, and the interval between hot water discharges, and notifies the state of the amount of hot water used for each application, so the user is The amount of remaining hot water that can be used is used to prevent the hot water from running out in advance, and by knowing the hot water running out in advance, the use of hot water for other purposes can be saved and the overall hot water can be saved. You can use hot water to prevent breakage, and you can make good use of hot water systematically. The amount of hot water used for each use shows a unique hot water discharge pattern depending on the use, for example, a small amount of hot water is frequently used in the kitchen, so it is reliably determined not only by the hot water discharge amount but also by the hot water discharge duration and the hot water discharge interval. .

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 is a hot water storage tank having a heat generating portion therein, 2 is a hot water discharge amount detecting means for detecting the amount of hot water discharged from the hot water storage tank 1, and 3 is a hot water discharge amount and hot water discharge based on a signal from the hot water discharge amount detecting means 2. A calculating means for calculating and storing the duration and the hot water discharge interval, a judging means for judging the use of the amount of hot water used based on a signal from the calculating means, and a judging means for accumulating and storing the discharged hot water amount according to the use, a judging means for the judging means 4 It is constituted by an informing means for informing the state of the amount of hot water used for each application by a signal from. 6 is a temperature detecting means. As shown in FIG. 2, the calculation means 2 comprises a timer unit 31, a calculation unit 32, and a first storage unit 33.

As shown in FIG. 3, the judgment means 4 comprises a second storage unit 41, a judgment unit 42, and a third storage unit 43. As shown in FIG. 4, the notification means 5 comprises a fourth storage unit 51, a comparison unit 52, and a signal generation unit 53.

In the above-described configuration, the usage of the amount of hot water used can be determined from the amount of hot water detected by the hot water discharge amount detecting unit 1, the duration of hot water discharge, the interval of hot water discharge, etc. It is possible to prevent hot water from running out.

Effects of the Invention As described above, according to the hot water storage type water heater of the present invention, the following effects are obtained.

It is possible to judge the usage of hot water used from the amount of hot water, the duration of hot water, and the interval of hot water, and to notify the usage status of hot water according to usage, so that the user can use hot water systematically and run out of hot water. It's less likely to happen.
