Abstract

PURPOSE:To make it possible to carry out the control so that the user can set the drive starting time of heating means and the total quantity of hot water produced in a day and to prevent after-burning from being carried out at an unnecessary time. CONSTITUTION:When a time-times adjusting switch 19 is used, and a time setting and a timer setting are carried out, main control means 17 stores them, and displays them on a time-time indicator 18. When a quantity of hot water is set by a hot water is set by a hot water quantity adjusting switch 20, a microcomputer 17 stores it. Inthis case, when it is assumed that the total capacity of a hot water storage tank 1 is 200 liters, and each of the capacities of a second thermister 12 and so on is 50 liters, and preset quantity of hot water is 300 liters, the entire hot water storage tank is heated up once. Thereafter, at a point in time when water reaches the second thermistor 12 by the water supply, the apparatus is again operated to subject water in the second thermistor 12 and downward to ''after-burning''. When this ''after-burning'' is carried out twice, hot water in a grand total of 300 liters can be supplied. Further, in a case where this '' after-burning'' operation is not completed within a predetermined time, even when the grand total quantity of hot water does not reach the preset quantity of heated water, the heating operation hereafter is compulsorily stopped.

Next, the operation of this embodiment will be explained.

First, when the user uses the time/timer adjustment switch 19 to change the time and timer settings, the control means 17 stores this and displays it on the time/timer display 18. indicate. When the amount of hot water is set by the hot water amount adjustment f[ls.
7. Memorize this. Here, the total capacity of hot water storage tank 1 is 200β, and the capacity of the second two mister 12 and below is 50β.
and the set amount of hot water is 300e. To achieve this hot water setting, drain the entire hot water tank once, n11
After heating, the second thermistor 12 is heated by hot water supply.
4 (Kakida l) ``At 1 point, turn the equipment 4 times (7, then reheat the water with the second thermistor 12 or less'').

If this reheating process is performed twice, a total of 300 β of hot water can be supplied. The above operation will be explained based on the drawings. .

The microcomputer 17 operates as a clock from the time set by the user, and when the timer reaches the time set by the user, the microcomputer 17 starts transmitting data to the shift l/register circuit 21 through the data transmission line 15. The operating values of the device are sent to the device. This is then latched by the launch circuit 22, and is further latched by the driver low 11 path 23. The operation of the burner 3 is started via the burner control means 26. At this point, -tW, 1iT1 Since there is water in the hot water storage tank, the first. The second and third thermistors are all sensing low humidity. 7.Then, the obtained temperature is converted to IJ↓4 resistance value, passed through the analog 1] gmarzi breaker circuit 24, 2, and converted to A-, -, and D by the In comparator circuit 27, and then the data f and i line 15 are converted. Assistance and monitoring are performed by the microcomputer 17 via the microcomputer 17.

Then, when the operation of No. 3 starts, the water in the Ljl'7g tank above No. 3 is heated,
First, the t-claw degree of the first thermistor 11 is l! Every time I press I, I turn towards TWAK and stand up. This situation is shown in Figure 3. Eventually, this state of affairs continued, and the island continued to exist.
The first thermistor 11 is △1. When the temperature reaches a lower TON, the main sub-means 17 detects this.

Then, the circulation pump 8 starts operating through the same route as when the operation starts. (Point A) By the action of the circulation pump 80, the water in the lower part of the hot water storage tank 1 is supplied to the upper part, and the temperature in the upper part decreases a little, and a layer of hot water is transferred to the burner 3.
is pushed down.

□ In this way, when the first thermistor 11 bottoms out to the temperature To'y F, which is △t2 degrees lower than TON,
The main control means 17 detects and h and stops the operation of the circulation □ pump 8. (Point E) At such mL, the circulation pump 8 repeats operation and stop, and the layer of hot water in the hot water storage tank>1 is gradually pushed downward, and accordingly, the second. Third
' The temperature of thermistors 1□2, 13 increases. Eventually, when the layer of hot water reaches the inlet of the circulation tube 8, the circulation pump 8 starts supplying hot water to the upper part. The temperature of the first thermistor 11 rises due to the combustion heat of the burner 3 while the circulation pump 8 is in operation, and finally reaches the boiling temperature TWAIm, and the microcomputer 17 detects this □. , the operation of the burner 3 and circulation pump 8 is stopped, and boiling of the entire hot water storage tank is completed.

(0 points) At this point, the microcomputer 17 has memorized all the hot water settings*3o'o l, so it is waiting for the remaining two "reheating" operations. Next, when the user pours hot water, the temperature of the third thermistor 13 decreases.
The temperature of the thermistor 12 of b decreases.

And the temperature of m12 thermistor 12 is T OF
When the temperature reaches □THAH, which is △t3 degrees lower than F, the microphone detects this and controls the burner 3 and circulation pump 8 again, and the second thermistor 12 and 5
“Reheat” oβ. Then, the first □ stage 11 reaches TWAK, and the first "reheating" is completed (point E). In order to complete this reheating operation twice, the main control means '17 detects the completion of the set hot water amount,
This prevents the equipment from being operated thereafter.

By adopting such a thermistor arrangement and control method, the amount of hot water can be set arbitrarily for each 504. □ FIG. 4 is also an operation sequence diagram of the hot water boiler of this embodiment, and the operation □ described above corresponds to the operation I in this figure. However, if the amount of hot water set by the user is greater than the amount of hot water required by the user on that day, as shown in operation H, the ``reheating'' operation with two sips is activated. A case may occur in which the hot water supply for that day ends without starting.In preparation for such a case, in this embodiment, at the same time as the timer setting time, a separate tapum count is set inside the microcomputer 17. (Reheating effective time) is started and turned off. Then, during the reheating waiting time and in between, this reheating effective time exceeds a predetermined time (8 hours in this case). Determine whether or not the temperature is exceeded.Then, when this point is exceeded, the subsequent "reheating" operation is canceled.

In the afternoon, 1. It is possible to prevent unnecessary "'trailing" idle operation from now on. .

As described above, according to the present invention, the total amount of heated hot water used by the water heater in one day can be easily controlled by the operation of a switch. It is possible to obtain the amount of heated hot water in several stages depending on the season, and the amount of hot water set is 1. There is no limit to the volume of the tank's voice. - Since the amount of hot water can be set to suit each user's individual hot water supply preferences and inputs, once the settings have been made, from now on, the user will be able to operate the furnace completely automatically without having to touch the furnace. , can provide the necessary and efficient hot water every day.

Furthermore, since "reheating" is performed at the bottom of the hot water storage tank, hot water can always be drawn from the top. You can also obtain specifications equivalent to water heaters that have
Is there an effect like that? , Also, in the unlikely event that the set hot water amount is
゛Even if it is left in a state where it is too large and the predetermined "reheating" is about to be completed, the unnecessary reheating will be stopped after the predetermined time based on the judgment of the reheating effective time. Since it is reset, natural heat dissipation can prevent unnecessary operation and trivial problems.
