When the sensed external temperature rises above the allowable range, the expansion coefficient is When the metal on the upper side is bent and separated from the contact to cut off the current, and when the temperature is low again, the above-mentioned metal piece returns to its original horizontal state and contacts the contact to pass the current, thereby switching the contact properly according to the sensed temperature. It is made of a conventional structure to supply or cut off the current while short-circuited or connected, this structure is the same or similar to that already widely used in household rice bowls, etc., so a detailed description thereof will be omitted.

And, on one side of the outer edge of the heat generating portion 2 is provided with a heat generating portion detection sensor 8 for continuously detecting the heat generated from the heat generating portion (2).

The heating part detecting sensor 8 is electrically connected to a current line 14 connected through one contact port 10 of the heating part 2 and the contact point of the water temperature detecting sensor 6. Irrespective of the sensing of the water temperature sensor 6, the temperature of the heating unit 2 is continuously detected.

The heat generating part detecting sensor 8 is connected in series to the current line 14 connected to the water temperature detecting sensor 6 and the first case 18 and the second by the insulating pad P. It is fixed insulated from the case 20.

The heating part detecting sensor 8 may be a general temperature fuse, and the fuse has a current line connected to the fuse by shorting its own contact by heat detected from the outside regardless of the flow of current. By blocking the current flowing through the (14) it essentially blocks the electricity supplied to the heat generating section (2).

The heat generating part detecting sensor 8 is preferably installed at a position adjacent to the heat generating part 2 so that the heat generated by the heat generating part 2 can be detected smoothly. Although it is shown to be installed adjacent to the outside of the heat generating unit 2, it is also possible to be installed between the heating pipes are formed in a zigzag form spaced at predetermined intervals, and in addition, the heat generating temperature of the heat generating unit 2 can be detected as effectively There are a variety of settings that can be made.

In the above description, the heating part detecting sensor 8 is made of a temperature fuse that cuts off the current by short-circuiting itself by a temperature detected beyond the allowable range, but is not limited thereto. A current fuse to cut off the current by shorting itself by the sensed current may be used.

In addition, the water temperature sensor 6 and the heating unit sensor 8 are the first case 18 and the second case in the same manner as the heating unit 2 by the insulating pad (P). It is fixed insulated from the spaces 18a and 20a of the 20.

When the installation and wiring of the heating unit 2, the water temperature sensor 6, and the heating unit sensor 8 are completed, the housing 4, that is, the first case 18 and the second case 20 is completed. The electrical supply line 12 is drawn out through the wiring grooves 18b and 20b formed in the wiring grooves 18b and 20b, and the packing member 24 is installed in the wiring grooves 18b and 20b to connect the electrical supply line 12 to the wiring groove 18b. After fixing to 20b, the first case 18 and the second case 20 may be combined to maintain watertightness.

Although it may be withdrawn from the gill or tail portion may be fixed, in addition to it may be withdrawn and fixed at various locations.

Next, with reference to the accompanying drawings a preferred operating embodiment of the water heater heater device according to an embodiment of the present invention in more detail as follows.

First, referring to FIG. 6, the housing 4 is placed in the seawater W contained in the water tank T, and one side of the electricity supply line 12 may be fixed to the housing 4 in a predetermined posture. Install a separate fixture (C) in the form of a hook on the fixed to one side of the water tank (T).

When the fixing of the housing 4 is completed as described above, the connection plug 16 of the electric supply line 12 is connected to a separate capacitor (not shown) to generate heat generated inside the housing 4. Part 2 generates heat and the heat generated in this way is transferred to the seawater W through the housing 4, so that the temperature of the seawater W contained in the water tank T is increased. The verification device D installed in the electric supply line 12 also operates to emit light.

When the temperature of the seawater W contained in the water tank T rises as described above, the water temperature sensor 6 installed inside the housing 4 detects the temperature of the seawater W. The detection sensor 6 is switched to the OFF state when the water temperature of the sea water (W) rises above the set temperature range to cut off the current in the heating unit (2) and check the installed in the electrical supply line (12) The device D is also switched off and turned off.

When the heat generating unit 2 does not operate as described above, the temperature of the seawater (W) contained in the water tank (T) no longer rises and falls below the allowable temperature, and thus the temperature of the seawater (W) is in the allowable range. When the temperature is lowered below, the water temperature sensor 6 detects this and switches back to the ON state to supply current to the heating unit 2.

Then, the heat generating unit 2 generates heat to maintain a constant water temperature, and the checking device D installed in the electric supply line 12 also operates together to emit light.

According to the temperature of the sea water (W) contained in the water tank (T) as described above, while the water temperature sensor 6 is properly switched to the ON / OFF state by controlling the operation of the heating unit (2) sea water (W) ) Can be kept constant at all times, it is possible to easily identify the operating state from the outside through the identification device (D).

Then, the water temperature sensor 6 is damaged or the electric shock or leakage of the sea water W contained in the water tank T is generated so that the water temperature sensor 6 smoothly maintains the temperature of the sea water W. If the heat generating unit 2 is not sensed and continuously operates irrespective of the temperature of the seawater W to generate excessive heat, the heat generating unit 2 continuously generates the heat generating temperature of the heat generating unit 2 adjacent to the heat generating unit 2. When the heating unit detecting sensor 8 detects this and detects an abnormal temperature range or more, it short-circuits the contact and cuts off the supply of current to the heating unit 2.

Therefore, the heat generating part detecting sensor 8 essentially blocks the current supplied to the heat generating part 2 when the heat generating part 2 generates excessive heat even if the water temperature detecting sensor 6 malfunctions. Therefore, it is possible to fundamentally prevent the occurrence of fire due to overheating or short circuit.

According to one embodiment described above, when the housing 4 is contained in the water tank T to keep the temperature of the sea water W constant, the live fish F or a part of the human body contained in the water tank T 7, 8, and 9 are provided with a contact preventing cover 28 on the outer side of the housing 4 to prevent direct contact and to provide heating. Doing is shown as an example.

The contact preventing cover 28 may be a mesh member (MESH) of a metal or synthetic resin material having a polymerized portion formed to cover the entire housing 4 in correspondence with the shape of the housing 4 described above.

The mesh member has a plurality of through-holes formed on the surface thereof, so that the seawater (W) is smoothly introduced and discharged, so that live fish (F) or the human body directly contact from the outside without lowering the heating effect by the housing (4). It is possible to prevent safety accidents caused by burns by preventing them.

And one embodiment is described as an example that the water heater device according to the invention is installed in the simple water tank (T) of the restaurant, but is not limited to this embodiment, but not shown in the drawings, but the plating on the surface of the metal It can be widely used in a plating tank or a large aquarium of a plating company that performs, and of course, it is possible to maintain the water temperature in an optimal state as described above and fundamentally prevent the occurrence of fire due to overheating and leakage.

Because it controls the water or solution contained in the tank can be maintained in the optimal state within the set temperature range.

And in the water heater device according to the present invention, if the heat generating part detection sensor for detecting the excessive heat generation of the heat generating unit is installed, the heat generating unit generates excessive heat regardless of the temperature of the water or the solution contained in the water tank By detecting and fundamentally cutting off the supply of current, it is possible to further improve the reliability of the product by preventing the damage of the product or the occurrence of a large fire.
