In general, a boiler may be a device that heats water and circulates the heated water through a water pipe to perform heating. Depending on the heating source for heating water, it can be divided into various types of boilers.

Here, in a boiler using electricity, a general electric boiler type is a method of heating water using a nichrome wire and a covered wire.

Such an electric boiler is low in energy efficiency because energy loss can occur when it is converted from electric energy to thermal energy. As this is adsorbed, there is a problem in that energy efficiency is lowered.

In recent years, in order to solve the disadvantages of the electric boiler, an electrode boiler that directly heats water by flowing an electric current between the electrodes, rather than an indirect method of heating water by heating a heating source, has been commercialized.

The electrode boiler is a boiler device that provides high thermal efficiency by using the same electricity as compared to an electric boiler. It is a boiler device that uses water as a heating medium by reducing it to generate heat.

In such an electrode boiler, two or more electrodes are arranged in a tank, and a voltage is supplied to the electrode to flow a current between the electrode and the electrode to directly heat the medium in the tank, and the medium in the tank is highly concentrated. There is a method consisting of an electrolyte solution of

On the other hand, in relation to the present invention, the electrode boiler of the electrode type generates heat due to ion conduction of water itself and limited electric flow, and is implemented with a uniformly balanced electric power. Recently, Republic of Korea Patent No. 10-1668985 (hereinafter referred to as the 'selection name') has been proposed.

The electrode boiler includes: a water tank having an internal space; It includes a plurality of electrode rods installed in the water storage space of the water tank.

The electrode boiler not only heats the heating fluid (water) to 100 degrees Celsius or more within 3 minutes, but also continuously produces water vapor of 130 degrees or more, heat generation efficiency does not decrease even at high temperatures, vibration and noise are small, and durability is large. It shows high heat generation efficiency compared to power consumption.

In addition, the water treated through the electrode boiler of the first name is rich in dissolved oxygen and is changed to weak alkalinity, and fine vortex generation is activated in the process of generating heat, which has a good effect on human health as well as increase production of agricultural and livestock products. show

However, the conventional electrode structure is intended to improve the thermal efficiency by using a heat pipe while solving the problem caused by the internal pressure when the water in the water tank is heated to increase the temperature.

However, since the electrode heater device of the conventional electric boiler is configured by immersing the electrode in the water tank as it is, it provides high thermal efficiency compared to the electric boiler, but there is a limit in improving the thermal efficiency.

By adding the hot water instantaneous heating unit 40 , not only heating the heating water through the electrode heating unit 30 , but also heating the hot water supply is possible.

As shown in FIGS. 4 to 7 , the hot water instantaneous heating unit 40 proposed in this embodiment is formed by winding a hollow heat exchange tube in a coil shape, and is supplied along the inlet 41a of the heat exchange tube.

As described above, the heat exchange coil molded body 41 formed by crossing the descending winding portion 41c and the descending winding portion 41d increases the heat exchange area with the heating water heated in the water storage space 10a so as to go up and down along the heat exchange tube. The spirally circulated hot water exchanges heat more quickly with the heating hot water W, and in particular, the inlet 41a connected to the hot water supply pipe 42 and the outlet 41b connected to the hot water discharge pipe 43 are located at the upper portion, respectively. Due to the relationship formed, it has a specificity that allows a simple connection of the hot water supply pipe 42 and the hot water discharge pipe 43 .

In particular, in the present invention, a plurality of heat exchange molded bodies (40A, 40B, 40C) are arranged to be stacked in a concentric structure, while a parallel water supply folder (42a) is disposed in the hot water supply pipe (42) to each heat exchange molded body (40A, 40B, 40B, The inlets 41a of the 40C) are connected in a parallel structure with the hot water supply pipe 42 through the parallel water supply folder 42a, and a water collection and drainage folder 43a is arranged in the hot water supply pipe 43 to each heat exchange molded body ( The outlets 41b of the 40A, 40B, and 40C are connected in parallel with the hot water supply pipe 43 through the water collection and drain folder 43a.

And, as in the present invention, when a plurality of heat exchange coil molded bodies 40A, 40B, and 40C are stacked and disposed in a concentric structure, hot water supply circulating the water storage space 10a through each heat exchange coil molded body 40A, 40B, 40C More stable heat exchange between the water and the heating water stored in the water storage space 10a is achieved, and as a result, it has the advantage that the hot water can be quickly heated and discharged.

On the other hand, in the present invention, the heat exchange coil molded body 41 is configured to achieve instantaneous heating of the hot water (W) circulating along the heat exchange pipe through heat exchange with the heating water stored in the water storage space (10a). It is preferable that the heat exchange coil molded body 41 is always impregnated with heating water, and each electrode 33 of the unit electrode bundle units 32A and 32B disposed in the water storage space 10a is also immersed in the heating water. Maintaining the impregnated state stably is advantageously efficient in heating the electrode.

However, the heating water circulating along the heating circulation pipe unit 20 is continuously evaporated and consumed by the heating of the electrode heating unit 30, and since self-exhaustion occurs in the circulation process, even if the heating water is consumed to a certain extent It is preferable to keep the water level of the heating water stored in the water storage space 10a constant at all times.

Accordingly, the lifting block 52 is arranged in a lifting structure in the water storage space 10a of the water tank 10 to ascend and descend according to the residual height of the heating water stored in the water storage space 10a.

For example, when the water level in the water storage space 10a is lower than the set height, the lifting block 42 descends and is more deeply impregnated with the heating water stored in the water storage space 10a to increase the water level of the heating water, and vice versa. When the water level in the water storage space 10a rises higher than the set height by the supply of supplemental water, the lifting block 52 rises and is impregnated with the heating water stored in the storage space 10a to lower the level of the heating water, Heating water stored in the water storage space should always maintain the set water level.

The elevating block unit 50 is configured to elevate the elevating block 52 through the elevating member according to the level value of the heating water detected through a water level sensor for detecting the water level in the water storage space.

When the heating water stored in the water storage space 10a by the lifting block 50 maintains the set water level, the electrode rods 33 of the unit electrode bundle units 32A and 32B arranged upright in the water storage space 10a. And, the heat exchange coil molded body 41 is always stably impregnated with the heating water, and as a result, the electrode heating action of the heating water through the electrode rods 33 of the unit electrode bundle units 32A and 32B, and heat exchange A quick and stable heat exchange action between the coil formed body 41 and the heating water can be achieved.

In this way, if the heating water stored in the water storage space 10a through the lifting block 50 is configured to always maintain the set water level, supplemental water is not supplied into the water tank through a separate make-up water supply pipe and valve, Even if the manager intermittently supplies make-up water in the water storage space 10a, it has the specificity of being able to maintain a constant set water level at all times of the heating water.

In addition, in this embodiment, the lifting block 52 is composed of a heat absorbing structure or a heat absorbing material that absorbs heat emitted from the heating water stored in the water storage space 10a, and the heating water is continuously discharged through the dissipation of the absorbed heat. The current loss of the electrode heating part due to heating of the heating water and the hot water is minimized by aiming for insulation and heating.

For example, in this embodiment, the elevating block 52 is composed of a hollow body, and heat oil 52a is filled in the elevating block 52, so that the elevating block 52 is heated water through the heat oil 52a. By absorbing the heat emitted from the heat sink, the heating water is kept warm.

In addition, in this embodiment, a tray 53 having a plurality of mixing holes 53a formed therein is formed on the outside of the lifting block part 50, so that the water stored in the water storage space 10a during the lifting process of the lifting block 52 is stored. Heating water is circulated up and down internally to maintain a uniform temperature up and down.

In addition, in this embodiment, as shown in Figs. 8 and 9, the reduced pressure vapor discharge unit 60 for forcibly sucking the residual air and moisture remaining in the water storage space 10a of the water tank 10 and discharging it to the outside. By adding , a phenomenon in which the electrode heating efficiency of the electrode heating unit 30 decreases due to the residual humidity in the water storage space 10a is suppressed.

The reduced pressure vapor discharge unit 60 includes a steam discharge pipe 61 formed in the upper half of the water tank 10 and an intake pump 62 for forcibly sucking in and discharging air in the water storage space 10a through the steam discharge pipe 61 . ) is included.

In this embodiment, the vapor discharged through the vapor discharge pipe 61 is condensed through air cooling, and then the condensed re-supply pipe 63 for re-supplying the condensed moisture to the water storage space 10a of the water tank 10. add

When the reduced pressure vapor discharge unit 60 is formed in this way, a phenomenon in which the electrode heating efficiency of the heating water through the unit electrode bundle unit decreases as a large amount of steam remains in the water storage space 10a is suppressed, and the recovered steam is condensed and supplied into the water storage space 10a, so that the loss of the heating water remaining in the water storage space 10a can be minimized.
