BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a submergible indirect underwater heater, and more particularly, to a submergible indirect underwater heater which includes a heat generating body formed in a straight tube shape and including a heat generating tube fixedly installed therein; The heat generating body is vertically fixedly coupled to the lower portion of the lid to be inserted into the internal space, the medium circulates the heat of the heat generating body in the internal space, and the exothermic transmission external member ; And a control means electrically connected to the heat generating body to set a temperature of the heat generating body and to adjust a temperature of the medium accommodated in the heat transmission external member according to the set temperature .

Generally, an underwater heater is used to maintain the temperature of aquarium water contained in a water tank and the temperature of a sewage treatment plant to be constant.

A general structure of the above-mentioned underwater heater will be briefly described, including a heat generating tube for generating heat and a control unit for controlling the operation of the heat generating tube. The shape of the heat generating tube is not limited to the required heat generating conditions, But is formed in a length range that can be installed in the water tank and is connected to the control unit, and a sensor rod capable of sensing the temperature of the water or the heating tube is installed in the vicinity of the heating tube .

However, in the conventional heater, since the heating tube is directly exposed to the outside, the heater is easily exposed to contamination and the lifetime is shortened.

To prevent this, even if a simple cover is attached to the heating tube, the amount of the medium between the heating tube and the cover is small, so that impurities are adhered or corroded to the outer surface of the cover.

In addition, since the heat pipe is exposed and stick-shaped, there is a problem that it is difficult to attach an additional weight or sensor due to a lack of space.

Further, since the temperature according to the current heater arrangement can not be confirmed, there is a problem that the manager must learn to maintain the constant temperature at all times through trial and error.

Meanwhile, as shown in FIG. 1, the Korean Registration No. 0485309 proposed by the present inventors includes a tubular body; A heating rod 1 inserted into the body and provided to be able to generate heat by an applied power source and to control the temperature of water contained in the installation member; A first filling material filled in the body so as to form a space between the outer surface of the heating rod and the inner surface of the body; And a second filling material filled in the space part, the second filling material being hardened after a predetermined time to fix the heating rod inserted in the body and to prevent water contained in the fitting member from flowing into the body .

However, as shown in FIG. 1 (b), as the use time passes, impurities are hardened on the outer surface and adhered or corroded.

The heat generating body 10 is formed in a straight tube shape and is formed of a heat generating tube whose inside is fixed by a ceramic material or silicon and is inserted vertically or horizontally into the medium to facilitate temperature conduction. In addition, the heat generating body 10 may have a plurality of different heater bundles other than the straight tube.

The exothermic transmission outer member 20 has a hollow rectangular cylinder or a cylindrical shape and is hollowed inside. The outer material is made of a high heat conductive thermoplastic plastic. The outer heat transfer transmission member 20 has elasticity and is resistant to external impact. A detachable portion for attaching a detachable portion can be formed.

A heat generating body 10 is inserted into the heat transmission external member 20. The heat generating body 10 is vertically fixed to the lower side of the lid 31 and inserted into the internal space, The inner space is sealed with the lid 31 provided with the packing 32 so as to circulate the heat of the heat generating body 10 without the medium flowing out to the outside.

5, the lid 31 is screwed to the upper portion of the heat-generating transmission outer member 20, and a packing 32, which prevents the refrigerant from leaking out due to the expansion of the medium, As shown in Fig.

That is, the lid 31 is screwed to the outer thread of the opening 22 to seal the opening 22 connected to the inner space from the outer space of the heat transmission outer member 20.

For example, a hole is formed in a central portion of the lid 31 so that the heat generating body 10 of a straight tube shape can be fixedly inserted, and a cable tube 12 electrically connected to the heat generating body 10 penetrates the hole And is vertically positioned in the inner space of the heat transmission outer member 20 through the opening 22.

The control means 30 is electrically connected to the heating body 10 to set the temperature of the heating body 10 and to adjust the temperature of the medium contained in the heating transmission outer member 20 according to the set temperature .

For example, the heated medium conveys upwardly and downwardly to heat the entire exothermic transmission outer member 20 to heat the water filled in the pool or the like.

Therefore, the phenomenon that the temperature of the water filled by the indirect heat of the exothermic transmission outer member 20 does not drop rapidly can maintain the water temperature at the place where the hot water is needed at all times.

In this case, the set temperature may be preset according to a predetermined rule in consideration of the temperature characteristic of the medium and the like.

The control means (30) is further provided with an internal temperature sensor for detecting an internal temperature and an external temperature sensor (102) for detecting an external temperature. Therefore, it is possible to evaluate whether or not the temperature of the heat transmission external member 20 rises according to the set temperature by the internal temperature sensor, and whether the submergible indirect underwater heater should be operated according to the current temperature through the external temperature sensor You can decide.

For example, a location-tracking dedicated app is installed in a smartphone terminal at a place exposed without a roof, and then the GPS signal is received and the position of the submersible indirect underwater heater of the present invention displayed on the GUI can be visually recognized.

Especially, in case of indoor, since the GPS signal is weak and the error range is wide, the WiFi module can not be used. Therefore, the WiFi module may be installed in the submersible indirect underwater heater to use the WiFi system of the present invention.

Alternatively, the present invention may use a short-range, low-power location module as a location tracking module, and may use a small, cheaper local wireless communication device (e.g., a beacon) based on Bluetooth low energy (BLE) technology.

In one embodiment, the Wi-Fi system of the present invention is capable of grasping the position and direction of a Wi-Fi signal in accordance with the intensity of a Wi-Fi signal emitted from each Wi-Fi module 300 in a room.
