Abstract

PURPOSE:To quickly complete the boiling by raising the thermal efficiency by enlarging the heat exchanging area of multiple heating units and circulating the burnt gas through the water heater vessel. CONSTITUTION:The water heater vessel 4 having in its upper and lower positions the connecting pipes 2, 3 connected to the bathtub 1 is housed in the heating vessel 5, and tubular heating units 6 are arranged in rows in the water heater vessel 4. The water heater vessel 4 has in its top a ventilation hole 7 opening to the space between itself and the heating vessel 5. Burners 8 are disposed under the heating units 6, and the heating vessel 5 is provided with a smoke pipe 9. The water in the bathtub 1 is circulated into the interior space between the heating units 6 and the water heater vessel 4 to heat the water. In this manner, the thermal efficiency becomes greater than prior bath boilers to allow a quick completion of heating.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a bath kettle that can quickly boil water.

(Prior art) Conventional bath pots raise the temperature by passing water through a spiral pipe above the heater or through a vibrator inside the pot, which has disadvantages such as poor thermal efficiency and increased fuel costs. there were.

(Problems to be Solved by the Invention) In conventional bathtubs, the heat from the burner does not effectively raise the temperature of the water, resulting in poor thermal efficiency and a considerable amount of heat being discharged to the outside.

In addition, the structure of the heat absorbing portion is complicated and the manufacturing cost is high.

The present invention was made to solve the above-mentioned problems, and has a structure that effectively absorbs heat to quickly boil water, increasing thermal efficiency and boiling water faster than conventional bath pots. It is intended to achieve this goal.

(Means for Solving the Problems) In the present invention, a water boiler container 4 having communication pipes 2 and 3 connected to the bathtub 1 provided above and below is housed in a heating container 5, and the water boiler container 4 includes: Cylindrical heating bodies 6 of circular, elliptical, square, and other shapes are arranged in a row, and water is boiled within the heating bodies 6.
An exhaust hole 7 is provided at the upper end between the water boiling container 4 and the heating container 5.
A gas, electric or other type of heater 8 is provided below the heating element 6, and a smoke exhaust pipe 9 is provided in the heating container 5, so that the water in the bathtub 1 can be drained between the heating element 6 and the water boiler container. This bath kettle is characterized in that it is configured to boil water by passing water through and circulating it inside the tub.

(Function) According to the present invention, the flame of the combustion gas of the heater 8 passes through the exhaust hole 7 and rises along the outer surface of the cylindrical heating element 6. Since the heat exchange area is large, the heat of the flame from the heat source such as gas comes into contact with the heating element 6, which has a wide area, and quickly boils water, so the water in the water boiling container 4 and the heating element 6 is quickly heated. The water is heated to a high temperature and boils water in a short time.

(Example) Embodiments of the present invention will be described below based on the drawings.

In the present invention, a water boiler 4 having communication pipes 2 and 3 connected to the bathtub 1 arranged above and below is housed in a heating container 5, and a cylindrical heating body 6 of an appropriately shaped shape is disposed inside the water boiler 4. At this time, the pitch and size of the heating elements 6 and the exhaust holes 7 are not particularly limited, and can be selected and determined as appropriate. good.

Further, as another embodiment of the present invention, as shown in FIG. 6, the heating body 6 and the bathtub 1 may be connected by a pipe 10 passing through the communication pipe 2. In this case, the pipe 10 is connected to the heating body. All 6 are connected to the bathtub 1 through the communication pipe 2.
With this configuration, the convection of water within the water heater 4 is ensured.

Further, below the heating body 6, a heater 8 such as an electric heater or various gas burners is provided. A smoke exhaust tube 9 is provided on the upper surface of the heating container 5 to exhaust smoke from the heating container 5. Further, as shown in FIGS. 3 to 5, water is present between the heating element 6 and the water boiler 4 inside the heating element 6.

Since the present invention is constructed as described above, when the present invention is used, when the heater 8 is ignited, the combustion gas rises along the outer surface of the heating element 6. At this time, the heating element 6 has a heat exchange area. Since the heating element 6 is wide, when heat is applied by a flame heat source such as gas, the heating element 6 is heated.

In particular, in the present invention, when a gas is used as the heat source, the exhaust hole 7 is provided at the upper end between the heating elements 6, so that the flame of the gas flows along the outer surface of the heating element 6. As it rises,
The heating element 6 is sufficiently heated, and since air is supplied from the exhaust hole 7, incomplete combustion of the gas does not occur.

Also, inside the water boiler 4, warmed water rises along the heating body 6, enters the bathtub 1 through the upper communication pipe 3, and cold water flows through the lower communication pipe 2 into the water boiler 4. heating element 6 inside
It flows into the gap below.

Therefore, inside the heating body 6 in the part near the heater 8,
By supplying cold water, the high-temperature combustion gas portion becomes a cold water portion, so that the combustion gas more easily conducts heat to the water.

Therefore, convection within the water heater 4 is also ensured.

(Effects of the Invention) As explained above, according to the present invention, the heat exchange area is large, so the thermal efficiency is much higher than that of the conventional method.Furthermore, the exhaust gas is passed through the water boiling container, which improves the thermal efficiency. It can be heated in a matter of hours. Moreover, it has an economical effect, such as being able to save heat sources such as gas by the amount of time that is shortened.
