Abstract

PURPOSE:To improve a heat absorbing efficiency by a method wherein a wide band-shaped main tube is molded integrally into a spiral shape with a predetermined pitch and the water in the main tube is forced to absorb the heat of the main tube heated by flame while the water is whirling in the main tube. CONSTITUTION:When the water is passed through the main tube 2 by opening a faucet and a combustor 8 is ignited, the flame is ascended from the lower part of the tube along the inclined surface of the main tube 2 molded integrally into the spiral shape as the flame is whirling to heat the whole of the main tube. The heat of the heated main tube is absorbed wholly and quickly without remnant with a high efficiency by the water flowing down through the main tube under being whirled.

Description

[Detailed Description of the Invention] The present invention relates to a heat exchanger that is mainly used built into a bathtub or other various heat exchange devices, and its purpose is to create a heat exchanger with a required slope to obstruct exhaust air. The heat exchanger body is formed by forming the main pipe into a spiral shape at the required pitch, and the flame heat is swirled up from below at a gentle speed along the spiral surface area of the main pipe. The body is heated evenly, tap water is continuously flowed into the body of the armpit, and the water is passed through the body while circulating in a wide band, so that the heat of the entire heated body is thoroughly and continuously. Absorbs with high efficiency, completely prevents waste heat from escaping, instantaneously and continuously boils a large amount of hot water in a short time, and facilitates hot water circulation and cleaning of the inside of the main unit. This makes it possible to significantly reduce fuel consumption and boiling time.

Traditionally, commonly available bath pots, or bodies with various water heater plates arranged in rows, are connected and integrated to allow water to pass through one or more, or circular pipes are arranged in a spiral shape. There are water heaters with built-in moldings and other types of water heaters, but all of them have a narrow internal area for heat absorption, and the flame heat is directed from the bottom of the main body to the upper chimney, in the form of a vertical line at a very high speed. In order to efficiently heat the entire outer surface of the built-in heat exchanger, the required amount of water flows into the tank and is stored in the tank, and many details will be explained in detail.

The main body pipe 2 that has been passed through is attached with a slope 3 at the required pitch and screwed into a two-piece type, and the water connection pipes 4 and 5 are attached to the required stirrups above and below the main body. The outer circumference is round,
The main body is rectangular and may have any shape, and 6 is a wire mesh covering the outer periphery of the main body, or a plurality of fin plates arranged in a line at a required pitch.

Next, an example of the case of configuring a bathtub with a built-in body according to the present invention configured as described in ), and various other heat exchange devices, as well as the heat absorption effect of flame heat and water circulation, and the effect characteristics. More specific details regarding the above are as follows.

As a first example, in the case of configuring a bathtub, the main body of the cover 7, which is formed of a metal plate so that the cover can be fastened, is integrated with the outside of the body of A. If you fasten it and fit the lower open end onto the combustor insertion port 8 or over the pet 9 which has a built-in combustor, you can easily assemble the above-mentioned bath kettle without the hassle of assembling the combustor. ,
Various heat exchange devices can be easily configured.

In I2...The case where the bathtub having the above structure is connected to the bathtub by a circulation pipe and hot water is discharged from the bottom of the bathtub will be explained as follows.

Connect the circulation pipes 10 and 11 to the water connection pipes 4 and 5 to the bathtub with the required joint pipes so that water can flow into the fitting tank,
In addition, the right open hole of the circulation pipe 11 is sealed with a stopper 12, and the hose joint pipe 13 fastened to the top surface of the water connection pipe 5 is connected to the faucet using the hose 14, and the faucet is opened. When water is passed through the body and the combustor is ignited, the flame heat flows from the bottom of the body up the slope of the two main pipes, which are integrally connected in a spiral shape; The heat of the heated main body is absorbed quickly and efficiently by circulating water that flows continuously from above the main body while swirling in a wide band shape, and is fitted into the water flow connection pipe of the lower part. A large amount of hot water at a desired temperature continuously flows out from the circulation pipe No. 10, as indicated by dots in the lower part of the tank, and the required amount of hot water is stored in the conventional tank water storage time.

In the above case, water flows in from the main body 1, endothermically heated water flows out continuously from below, but the above procedure can also be easily carried out when water flows in from below the main body and continuously flows out from above.

Thirdly, if the water temperature in the tank drops, the coupling pipe of the circulation pipe in tank 10 or 11 is sealed from the tank. Then, the lower layer water in the tank flows from inside the main body and becomes endothermic high-temperature water while swirling upward, and flows out into the upper layer water in the tank without stagnation in the container, so that the temperature can be easily raised. .

1114... When hot water at a desired temperature is to be flowed out, the above objective can be easily achieved by adjusting the amount of water flowing into the main body by adjusting the opening and closing of the faucet.

Fifth, when recovering waste heat escaping from an existing chimney, it is possible to form a main body that can be installed inside the chimney and build it into the chimney. Waste heat can be recovered.

6th G; ,'...In the uninvention, tap water is mainly forced to flow inside the body during boiling water, so the entire heat-absorbing inner surface of the body is cleaned by constant circulating water pressure, so there is little resistance to scale,
In particular, when cleaning, open the faucet fully and force tap water to flow through the faucet, allowing the water pressure in the flow to easily and easily clean the area.

As explained above, the present invention has an extremely simple structure, is suitable for mass production, is trouble-free, and has an extremely wide heating and heat absorption surface by swirling upward passage of the flame heat that can be ignited without any problem with combustion exhaust. The entire outer surface of the main pipe is evenly heated, and the water circulating while circulating inside the main body absorbs conductive heat with high efficiency, allowing a large amount of hot water to flow out in a short time and allowing convective circulation. This heat exchanger is characterized by its ability to significantly reduce fuel consumption and hot water time.

In addition, in the present invention i, if the main body's outer periphery 6 is covered with a wire mesh or if fin plates are integrally arranged in a row at a required pitch, the effect can be expected to be even more effective.
