Generally, tap water contains hypochlorous acid called chloride and carbon dioxide gas, so if you use this tap water to make coffee or tea,
It was difficult to obtain delicious coffee etc. without removing the scale. Since limescale and carbon dioxide gas are removed when tap water is boiled, tap water is usually poured into a container such as a kettle and brought to a boil before being used for coffee. However, each time you need boiling water, it takes a lot of time and effort to boil the water using a container such as a kettle.
On the other hand, constantly heating a container of water to bring it to a boil has the disadvantage of not only running the risk of overheating, but also increasing the amount of energy used to keep the water boiling all the time. It was hot. Also, if a commercially available household water heater is equipped with a function to boil water, there will be no problem, but with the above water heater, if water is boiled in its hot water tank, the hot water will not be hot. There is no structure in place to safely and reliably release the abnormal pressure that occurs in the tank to the outside, or to prevent the hot water from scattering from the hot water inlet due to steam when discharging hot water. Unless this problem is resolved, there is always a great danger, which is why home water heaters are still not designed to produce hot water. For this reason, boiling water is often generated by heating the water in a water heater and then reheating it in a kettle, etc. This not only takes time and effort to make drinks and foods that require boiling water, but also This was extremely uneconomical, as it had to be transferred to another container and reheated.

Next, to explain the operation, first insert the power plug 47 into the power source and then press the push button 42, the solenoid valve 12 is energized, the valve 12d opens, and the tap water flows from the water supply pipe 11 into the valve body 12a. The water flows through the water pipe 13 and is fed into the hot water tank 7 from the bottom of the water pipe 13 through the inflow cylinder 14, and when the hot water tank 7 is full, when you release the push button 42, , the changeover switch 32 is the heating heater 1
Switch to 0 side. Note that while the solenoid valve 12 is operating, the reheating heater 22 also tries to be energized, but if the water temperature of the water discharge control sensor 29 is below 75°C, its normally open contact 29a continues to open and the reheating heater 22 is turned on.
The reheating heater 22 does not generate heat because it is not energized. By switching the changeover switch 32, the heater 10 is energized, generates heat, and heats the water in the hot water tank 7. When the temperature of the hot water in the hot water tank 7 reaches approximately 85° C., the hot water temperature control sensor 17 is activated, and the normally closed contact 17b of the relay (not shown) opens to cut off the power to the heater 10.

Next, when hot water is required, the push button 42 is pressed to switch the selector switch 32 so that the energizing circuit on the solenoid valve 12 side is closed. For this reason, solenoid valve 1
2 is opened, and tap water is passed through the water conduit 13 and the inlet tube 1.
4 into the hot water tank 7. At this time, since a baffle plate 16 is provided in the hot water tank 7 above the inflow tube 14, the tap water rises in the hot water tank 7 while being diffused in the horizontal direction by the baffle plate 16. Due to the inflow of tap water, the hot water in the hot water tank 7 enters the guide tube 21 from the inlet 21a of the reheating device 20, and enters the heating tube 2 from the bottom of the guide tube 21.
4 and flows into the outflow cylinder 27 from the connecting pipe 28. Here, the hot water temperature is detected by the water discharge control sensor 29, and if the detected temperature is approximately 75°C or higher, a relay (not shown) is energized by the detection signal from the water discharge control sensor 29, and the normally open contact 29a is energized. close it. As a result, the reheating heater 22 is energized and generates heat, and thereafter, the hot water flowing into the heating tube 24 is heated by the reheating heater until it becomes hot water, and then passes from the connecting pipe 28 to the outflow tube 27.
The hot water flows into the hot water conduit 30 through the hot water. The hot water, along with the steam generated when heating hot water,
The hot water is fed into a tank 31 for vapor diffusion, flows down the bottom of the tank 31, and is discharged from the discharge port 31a to the hot water supply port 33 of the hot water tap section 6. At this time, the steam is vigorously jetted into the tank 31, but the jetting force is diffused in the tank 31 and is significantly weakened, so when the hot water is discharged from the hot water supply port 33, the hot water scatters due to the force of the steam. However, it is not discharged. In addition, the steam whose jetting force is significantly weakened by being spouted into the tank 31 hardly forms a steam body, and is in a state close to steam, and most of it flows through the steam vent in the upper part of the inner chamber a of the tank 31. The steam enters the outer chamber b of the tank 31 through the vent hole d and is discharged as steam or water to the outside of the hot water tapping section 6 through the steam exhaust hole 31b. Further, the remaining steam is discharged from the discharge port 31a of the tank 31 in the form of steam.

When most of the 85°C hot water in the hot water tank 7 has been used up and the temperature of the hot water flowing into the outflow tube 27 through the reheating device 20 becomes approximately 75°C or lower, the water discharge control sensor 29 detects the temperature and uses the detection signal to de-energize a relay (not shown) to open the normally open contact 29a and cut off the power to the reheating heater 22. That is, the generation of hot water is stopped. In this case, a display device (not shown) may inform the user that hot water cannot be generated.

Although the present invention has been described with reference to an example in which the water conduit 13 is connected to the hot water tank 7 via the inflow tube 14,
The water pipe 13 may be directly connected to the hot water tank 7, or the reheating device 20 and the hot water pipe 30 may be directly connected without the outflow pipe 27. In this case, the water discharge control sensor 29 is connected directly to the hot water pipe 30. The present invention also works even if the device is installed by inserting it in the middle of the piping.

(1) When the reheating heater generates heat, the hot water in the hot water tank passes through the reheating device, and the water discharge control sensor installed in the middle of the hot water conduit confirms the temperature of the hot water. Since the reheating heater is energized to obtain hot water only when the temperature is suitable for generation, there is no risk of the reheating heater causing a dry heating phenomenon, and hot water can be obtained safely. In particular, when the heating tube with a built-in reheating heater is made of ceramic material, the heating tube is made to generate heat when only about half of the water is flowing into the heating tube, or when there is no water at all. By passing water through the heating tube, there is no possibility that the heating tube will be cracked or cracked and the function of the reheating device will be impaired.

(2) Also, since water is supplied to the hot water tank via a solenoid valve installed in the middle of the water supply pipe,
The flow rate to the hot water tank is always fixed compared to when manually operating a drain pot, etc., and since this flow rate is fixed, the discharge of hot water can also be quantified, and as a result, the reheating heater can be controlled by the water discharge control sensor. In addition to this, it is possible to always produce boiling water at a constant temperature.

(3) Furthermore, when the solenoid valve is closed, the power supply to the reheating heater is blocked, and conversely, the energization circuit on the heating heater side is closed, so that the reheating heater and the heating heater are connected. By energizing both at the same time, there is no possibility that the contracted current for ordinary households will be exceeded, and it is possible to always use the device within the contracted current.

As explained above, water is passed into the hot water tank by opening the solenoid valve, and by checking this water flow with the water discharge control sensor, it is determined whether or not to operate the reheating device. This ensures that the reheating heater does not run dry, and since the amount of water flowing into the hot water tank is quantified by the solenoid valve, the flow rate is variable when the reheating device is activated. By doing so, there is no possibility that only steam will be ejected before the hot water is discharged, or that low-temperature hot water will be discharged, making it possible to always safely obtain hot water at the required temperature. Water boilers have many excellent features in practical use.
