Fluid heater {FLUID HEATER}

The present invention relates to a fluid heating device, and more particularly, to a fluid heating device that can heat a fluid to reach a desired temperature within a short time, and is easy to handle, such as washing by reducing the weight.

In general, the fluid heating device is widely used in coffee vending machines, cold and hot water purifiers, etc., and its range of use is gradually being extended in general homes, restaurants, offices, and public places.

By the way, the conventional water heater has been attached to the fluid heating device, for example, Sheath Heater in close contact with the outer wall of the hot water tank containing the water or other liquid contents to be heated to heat the resistance heat of the sheath heater A method of heating a liquid content, that is, a fluid such as water, by injecting the sheath heater directly into the hot water container or by directly inserting the sheath heater into the hot water container has been used.

However, the method of heating the contents in the hot water tank by heating the contents of the hot water tank by closely attaching and attaching the sheath heater to the outer wall of the hot water tank, requires a considerable time to heat the contents in the hot water tank. The maximum temperature is 800 ℃, so if there is no proper safety device or temperature control device, there is a high risk of fire. In addition, it is necessary to have a heat insulation structure around the hot water tank and heater to increase the thermal efficiency, which takes up a lot of space and additional cost. There is a problem that this is necessary.

The technology introduced to improve the problem of the method of heating the contents with the sheath heater attached to the outer wall of the hot water tank, inserts the sheath heater directly into the hot water container containing the fluid such as water directly to the contents to be heated The fluid is heated by contact.

1 is a view showing a conventional fluid heater, for example, a sheath heater.

Conventional fluid heating apparatus 10 has a cap (2) formed with a coupling means to be coupled to a fixed object such as a coffee vending machine or a cold and hot water purifier on the upper side, and a pipe-like appearance formed on the lower side of the cap (2) It consists of two or more stainless steel heating pipes (4).

In such a heating pipe 4, a wire having a predetermined thickness made of an alloy such as nickel-chromium or iron-chromium is wound around the heating element and the heating element, and the heat generated from the heating element is excellent in thermal conductivity and electrical insulation. The magnesium oxide layer (MgO) that serves to transfer is included, the stainless steel to form the outer surface is to protect the heating element and the magnesium oxide layer wrapped.

Magnesium oxide is widely used for refractory materials, crucibles, magnesia cement, etc. because of its extremely high melting point of 2,800 ° C and boiling point of 3,600 ° C.

Stainless steel is a special steel containing about 12wt% or more of chromium (Cr), which has a beautiful surface and excellent resistance to corrosion, making it a steel material that can be used for various purposes without surface treatment such as painting and painting. Since chromium has a very thin chromium oxide film (20 ~ 30um) on the surface of stainless steel and acts as a passivity layer that blocks oxygen invading into the metal base, the chromium does not rust easily. It is used as a protective film of the heating device (10).

The conventional fluid heater 10 having such a configuration can produce high heat up to 800 ° C., and its stability and reliability have been proven in various fields for a long time and are widely known as heaters.

However, in the above-described conventional fluid heating apparatus, since heat is transferred to a fluid such as water only after passing through a thick magnesium oxide layer and stainless steel generated in a heating element, the magnesium oxide layer is a material having excellent thermal conductivity. This elapses until there is a problem that the temperature of the water starts to rise.

In addition, since the latent heat inherent in the magnesium oxide layer is affected by the size, thickness and size of the magnesium oxide, it is not easy to control the latent heat.

For example, if the size of the magnesium oxide layer is increased, the latent heat lasts for a long time, and thus the influence on the change of the temperature of the fluid is increased. In other words, the user heats the water by applying power to the fluid heater to obtain the desired temperature of the fluid. When the power is applied until the user reaches the desired fluid temperature, the latent heat of the magnesium oxide layer The temperature will exceed the desired temperature. That is, the heat is not immediately cooled in the magnesium oxide layer that is a heat transfer material of the fluid heater 10 even after the power is cut off.

Therefore, when the user wants to obtain a fluid having a desired temperature, the fluid temperature must be cut off before the user reaches the desired temperature, so that the desired temperature is reached by the latent heat of the magnesium oxide layer. However, since the latent heat is difficult to predict, it is not easy to exactly match the temperature of the fluid to the temperature desired by the user, and an additional controller must be provided to exactly match the temperature.

In addition, if the contents in the hot water tank are left or used for a long time, sediment, bacteria, etc. are generated in the hot water tank, so that they cannot be used hygienically, and the hot water tank and the fluid heating device 10 must be periodically cleaned. Each heating device 10 should be separated and washed separately. However, the fluid heating device 10 has a problem that it is not easy to handle, such as cleaning because the weight is heavy because the insulator is considerably used in consideration of electrical safety.

In addition, since the conventional fluid heater 10 consumes all of the fluid in the hot water tank, new fluid is supplied and a considerable time is required to heat it above the set temperature, so that the user must wait for a considerable time to use hot water. There was discomfort.

The present invention is to solve and complement the problems caused by the conventional fluid heating apparatus as described above,

It is an object of the present invention to provide a fluid heating device capable of heating a fluid to reach a desired temperature within a short time.

Another object of the present invention is to provide a fluid heating device that is easy to handle, such as washing by reducing the weight.
