Description

Storage type hot water heater for submarine

The present invention relates to a submarine storage-type water heater that is installed in a submarine to provide hot water, and more specifically, to a submarine storage-type water heater that is installed in a submarine having a special environment so as to be able to withstand shock and vibration, has a waterproof function to prevent water from flowing into the interior of a rear casing where various electrical equipment is located, and is further provided with a suppressor to block excessive current from being supplied to the water heater.

In general, submarines are combat vessels that operate underwater and engage in combat, and are equipped with hot water heaters that can supply hot water to the submarines.

The above water heater is a prior art technology, as disclosed in Korean Patent Publication No. 10-2017-0116704, which comprises a body having an inlet and an outlet; and a heating means installed in the body and comprising a heater section and a heating section.

The submarine's interior is narrow and it operates underwater, so vibration and rolling pitching occur. Therefore, it must be designed to withstand vibration and shaking, be light in weight, and be easy to install.

However, when using the water heater of the above prior art, since the body is directly attached to the wall inside the submarine and installed, external impact and shaking may be directly transmitted to the electrical equipment configured inside, which may cause deformation or dislocation from the installed position and result in failure. In particular, the electrical equipment configured inside may dislocate and the wires may become tangled, and as a result, the wires may overlap and a short circuit may occur, causing a large amount of current to flow momentarily, resulting in failure of the electrical equipment or a fire.

In addition, the above water heater has a problem that water can flow into the interior where the electrical equipment and heater rods are installed, which can cause various safety accidents.

The above water heater has a problem in that water cannot escape through the discharge port installed on the side because it tilts due to rolling pitching, and water vapor generated inside is discharged through the discharge port, which may cause malfunction.

Below, the configuration of the present invention is described in detail based on the attached drawings.

The present invention is a storage-type hot water heater (10) for supplying hot water by being installed in a submarine with a special environment, and is composed of a hot water storage tank (300) in which cold water is heated and stored, and front and rear casings (100) (200) that protect the hot water storage tank (300) and are separated into front and rear.

The above rear casing (200) is made of polyurethane resin, and has a reinforcing bar (200a) formed in a grid shape on the inside to absorb external impacts and withstand shaking while reducing the overall weight, and a connecting flange (210) configured to be installed vertically on the wall surface inside the submarine on both sides of the rear, an injection pipe screw hole (220) and a supply pipe screw hole (230) formed on the upper side, a cable insertion portion (240) formed on the side to allow a cable to be inserted, and an installation space (250) formed so that various electrical equipment (400), an injection pipe (310), and a supply pipe (320) can be installed inside, and a packing joining groove (260) formed on the front edge to seal the front casing (100) with a stud bolt (500) and to allow a waterproof packing (600) to be inserted to prevent water from flowing into the inside of the rear casing (200).

Figure 5 is a drawing showing the configuration of a sealing member, and Figure 6 is a cross-sectional view showing the configuration of a sealing member.

A double bolt structure sealing member (700) composed of a casing bolt (710) and a finishing bolt (720) is formed in the above injection pipe screw hole (220) and supply pipe screw hole (230) to prevent water from flowing into the interior of the rear casing (200).

A first packing (710a) is configured between the above casing bolt (710) and the rear casing (200) to prevent water from flowing into the injection pipe screw hole (220) or the supply pipe screw hole (230).

In addition, a second packing (720a) is configured between the casing bolt (710) and the finishing bolt (720) to prevent water from flowing into the outside of the injection pipe (310) or the supply pipe (320).

The front casing (100) above is made of polyurethane resin, and a reinforcing bar (100a) is formed in the same manner as the inner surface of the rear casing, a pressurized protrusion (110) is formed on the rear surface to allow the waterproof packing (600) to be pressurized and sealed, and a joining space (120) is formed so that a hot water storage tank (300) can be installed inside.

Figure 7 is a drawing showing the configuration of a hot water storage tank, and Figure 8 is a front view showing the configuration of a hot water storage tank.

The above hot water storage tank (300) is made of stainless steel, and an injection pipe (310) is installed on the lower side to supply cold water, a supply pipe (320) is installed on the upper side to supply hot water stored therein to the outside, an installation bracket (340) is configured on the rear side to enable various electrical equipment (400) to be installed away from the hot water storage tank (300), and a heater unit (900) is configured to heat the cold water stored therein.

Figure 9 is a drawing showing a state in which hot water is supplied to the supply pipe while the water heater is tilted.

If the above supply pipe (320) is connected to the hot water storage tank (300) without protruding, and the hot water storage tank (300) tilts during the rolling pitching process, hot water is not supplied and steam formed inside is discharged through the supply pipe (320). To prevent this, an extension pipe (330) that extends forward is installed at the end of the supply pipe (320) connected to the hot water storage tank (300) so that hot water can be supplied smoothly.

At this time, the extension pipe (330) extends 30 to 45 mm forward from the end of the supply pipe.

Meanwhile, the electrical equipment (400) is composed of a temperature control device (410), an overtemperature switch (420), an automatic trip device (430), and a terminal block (440).

The above temperature control device (410) is set to 65°C and operates the heater unit (900) until the temperature is reached, and hot water at 65°C is discharged toward the supply pipe (320) and supplied to the outside.

The above over-temperature switch (420) ensures that when the hot water temperature exceeds 95°C due to a failure of the temperature control device (410), the hot water control device (410) safely stops operating by the automatic trip device (430).

That is, the electrical equipment (400) is not coupled to the hot water storage tank (300) or the rear casing (200), but is installed on the installation bracket (340) formed on the rear of the hot water storage tank (300), so that it is maintained in a state separated from the hot water storage tank (300), and thus, even if there is an external impact or shaking, it is not transmitted to the electrical equipment (400) and can be maintained in a state of being firmly coupled to the installation bracket (340).

Figure 10 is a drawing showing a state in which a suppressor is installed in a hot water heater, Figure 11 is a front view showing the configuration of the suppressor, and Figure 12 is a cross-sectional view showing the configuration of the suppressor.

When a high current is supplied momentarily while supplying DC current to the water heater (10) of the present invention, a suppressor (910) is further configured to detect and block the supply so as to protect various electrical equipment (400) of the water heater (10).

The above suppressor (910) is configured with a lamp (910a) and a power switch (910b) on the front, and a terminal block (910c), an electronic contactor (910d), and a surge protection device (910e) are electrically connected inside.

And, if the lamp (910a), power switch (910b), terminal block (910c), electronic contactor (910d), and surge protection device (910e) are not installed directly on the inner surface of the housing (911) of the suppressor (910), but rather a protective bracket (920) is installed on the inner surface of the housing (911), and the lamp (910a), power switch (910b), terminal block (910c), electronic contactor (910d), and surge protection device (910e) are combined with the protective bracket (920) so that they are firmly fixed without being detached even when an external impact is applied to the suppressor (910) or it is shaken, the present invention is completed.

The submarine storage-type water heater (10) configured in this way is installed in a submarine with a narrow space and severe rolling pitching. Even if the water heater (10) tilts, the phenomenon of water vapor being discharged by the extension pipe (330) extended to the supply pipe (320) is prevented and hot water can be supplied smoothly.

And according to the present invention, since the electrical equipment (400) installed in the hot water storage tank (300) is connected to the installation bracket (340), it can be firmly connected even when external impact or shaking occurs, and the electrically connected wires do not get tangled and can operate stably without failure.

The above are only preferred embodiments formed with some improvements of the present invention, and are in no way intended to limit the present invention, and any equivalent changes or equivalent changes made to the improvements of the present invention, or combinations not shown in this specification, should all be included within the protection scope of the present invention.
