The present invention relates to a heating apparatus for a water heater, and more particularly, it is designed to improve the thermal efficiency and durability by forming a surface area increasing means that can increase the thermal efficiency to the top of the heater body for heating the water heater.

In general, a water heater is a heating mechanism used to increase the boiling temperature of water by installing a heater generated by electricity at the bottom of the water tank.

Conventionally, a conventional water heater is provided with a lid 11 capable of opening and closing at an upper opening, and having a bottom plate 20 on a bottom surface of the body canister 10, and a current below the bottom plate 20. When it is supplied is largely composed of a heater unit 30 to generate heat by boiling water.

The heater 30 is fixed to the bottom of the bottom plate 20 by fixing means such as bolts, and the heating wire 32 is heated by connecting power to the heater 30 so that the bottom plate ( 20) is delivered to the water or food contained in the water bottle.

The heater 30 has a bottom plate in contact with the heater body 31 while the heating wire 32 generates heat when the power supply is connected in a state in which the heating wire 32 is molded to be wrapped with the heater body 31. Heat is transferred from 20 to the contents.

In addition, at one end of the casing that protects the water tank 10 from the outside, a control unit 40 that is operated by a user to adjust and control a set temperature of water is provided.

Conventionally, the upper surface of the heater body 31 surrounding the heating wire 32 has been formed flat.

Therefore, if the bottom surface of the bottom plate 20 and the upper surface of the heater body 31 remain in the same plane as the whole while installing the heater body 31, the heat transfer effect can be normally exhibited in use, but the probability Is not very high.

The reason for this is that when the heater body 31 is tightly tightened by bolts while the heater body 31 is in close contact with the bottom of the bottom plate 20, the bottom plate made of a thin plate bends or deforms at its tightening position. Is generated.

In addition, when the heat is applied to the repeated use of the water heater, when the bottom plate 20 is inflated and not used, the shrinking process is repeated, so that the bottom plate 20 cannot be kept flat.

Therefore, not only is the area ratio at which the upper portion of the heater body 31 maintains contact with the bottom plate 20 is low, and even the heater body 31 and the bottom plate 20 are not even contacted at all. The space is formed entirely between the) to cause the heat generated from the heater body 31 is not normally delivered to the food contents of the upper plate 20.

In addition, since the upper surface of the heater body 31 is flatly formed, the surface area to be generated is low and heat cannot be evenly transferred to the bottom plate 20.

As such, when the heat generation surface area is low and the thermal efficiency lower than the normal thermal efficiency is used due to poor contact state, the heating wire 32 embedded in the heater body 31 requires excessive heat generation temperature and time over the capability, thereby lowering durability. .

Therefore, despite the use of a relatively short time, the heating capacity of the heating line 32 is not only to be frequently replaced by a short circuit due to deterioration or overheating, there was a closed end that the overall efficiency of the water heater 100 is lowered.

Therefore, there was a problem that the durability and reliability of the product is lowered.

An object of the present invention is to provide a heating device for a water heater to improve the durability and reliability of the product.

Another object of the present invention is to provide a heating device for a water heater that can give economic benefits by reducing the power consumption of the product by reducing the heating time of food, including water due to the increased thermal efficiency.

The object of the present invention, the water bottle portion 10 having a predetermined volume and the upper opening;

Heater which is installed on the bottom surface of the bottom plate 20 inside the water bottle part 10 and generates a predetermined amount of heat when power voltage is applied through the heater body 31 having the heating wire 32 therein, to cut off or warm water. Section 30;

In the configuration consisting of a control unit (40) configured to be outside the water bottle (10), the temperature control in the water bottle (10) while being associated with the heater unit 30;

The surface area increasing means 33 is formed between the heater body 31 and the bottom plate 20 of the heater unit 30.

Therefore, the upper portion of the heater body 31 improves the contact area to the bottom plate 20, and the area where heat is dissipated is increased, thereby improving heat transfer efficiency.

In addition, it is possible to improve the durability and reliability of the water heater product including the heater.

Hereinafter, described in detail by the accompanying drawings a preferred embodiment of the present invention as follows.

The water bottle portion 10 has a predetermined volume and is open at the top thereof to be selectively opened and closed by the lid body 11.

The bottom plate 20 of the inner bottom surface of the water intake unit 10 is provided with a heater unit 30 that generates a predetermined amount of heat when the power supply voltage is applied to cut off or warm the water.

In addition, a control part 40 is formed outside the water bottle part 10 to control and control the temperature of the water in the water bottle part 10 while being connected to the heater 30, so that the water contained in the water bottle part 10 is formed. Temperature setting and adjustment can be done easily.

On the other hand, the surface area increasing means 33 is formed in the upper portion of the heater body 31 of the heater unit 30 to which the present invention is applied.

As shown in the drawing, the surface area increasing means 33 is composed of an uneven portion 34 having a predetermined spacing and arrangement from the center of the body to the outside and having a peak 34a and a valley 34b repeatedly formed.

That is, the uneven portion 34, which is the surface area increasing means 33 constituted by the heater body 31, has a predetermined arrangement and spacing so as to be repeated from the center to the outside while having a peak 34a and a valley 34b. Since it is formed, the surface area can be increased by the concave-convex portion 34 in close contact with the bottom surface of the bottom plate 20 of the water container portion 10.

As shown in the drawing, the uneven portion 34 formed by the surface area increasing means 33 can be set in various ways such as a circular configuration in which a radial configuration and a circular waveform are repeatedly configured outwardly from the center. It is to be noted that all such configurations are also included in the configuration of the present invention.

In addition, the spacing and depth of the peak 34a and the valley 34b in the concave-convex portion 34 configuration, which is the surface area increasing means 33, may be variously designed according to the characteristics and characteristics of the product.

Therefore, when installing the heater body 31 to the bottom plate 20 bottom surface of the water bottle 10, the surface area increasing means 33 to the upper surface of the body so that the bottom plate 20 is flat or curved by the uneven portion 34. Even if bent, at least one portion of the uneven portion 34 may be in contact.

In addition, since the area exposed to the upper portion of the heater body 31 is improved, the thermal efficiency transmitted through the bottom plate 20 can be increased, and the heat source generated through the heating line 32 is transferred to the entire bottom plate 20. Since evenly delivered, it is possible to significantly shorten the heating time of the water or food contained in the water bottle.

On the other hand, the heat transfer member 50 may be installed between the bottom plate 20 and the heater body 31.

That is, the bottom fixing groove 21 of the bottom plate 20 is provided with a heat transfer member 50 made of aluminum, lead, or copper made of nonferrous metal having a higher thermal conductivity than ferrous metal.

At this time, the surface of the heat transfer member 50 is to be dug small grooves to improve the surface area.

Accordingly, the heat emitted from the heater body 31 is transferred to the bottom plate 20 through the heat transfer member 50 having a high thermal conductivity, thereby improving the contact ratio between the heater body 31 and the bottom plate 20 to improve the overall heat efficiency of the water heater. It can be increased.

In the drawings, reference numerals are a fixing plate 12, a heat insulating material 13, and a fastening member 14 for installing the heater body 31 on the bottom plate 20.

According to the configuration of the present invention as described above, it is possible to improve the contact area between the heater body and the bottom plate and to increase the surface area where heat is dissipated, thereby improving thermal efficiency.

In addition, it is possible to prevent the heater wire from being locally heated and disconnected, thereby improving durability of the entire heater and the water heater.

And, because it is possible to heat the food or water contained in the water bottle more quickly, it is a very useful design that can give economic benefits by reducing the power consumption.
