Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water heater can body. The water heater can body of the present invention has an independent tank shape for heating and hot water supply as well as for naturally forced circulating hot water (replacement of a bath kettle), and the other three functions are incorporated in the can body. With a heat exchange configuration not found in hot water boilers, in conventional water heaters, heating and hot water are supplied from the same tank through a pipeline, and once hot water is used for heating It eliminates the problem of being contaminated with dirty hot water, and the present invention is an independent tank shape as described above, and the function is a can body that is comparable to that using multiple devices. . Particularly in cold regions, it is a water heater can body having a characteristic that an antifreeze liquid can be injected and used in a pipeline connecting the heating tank and the tank.

The conventional vertical water heater is a device that has a spiral pipe or a heat exchange water chamber built-in and is used for hot water supply for heating by raising the temperature of hot water.The burner is horizontal combustion and extends from the combustion chamber to the exhaust port. Various shields have been devised and installed to increase the heat absorption coefficient, but once combustion is interrupted, it rapidly changes the cooling air by inducing cold air from the gap or burner intake port, which is a cylinder. There is a heat absorption part at the top of the mold, and the rise of hot gas is a natural theorem and is a drawback of the vertical water heater, which leads to waste of fuel consumption. Although it is not installed, even if it is installed, since it is the horizontal and horizontal combustion of the burner as described above, there is a heat absorption part above the combustion chamber and the circulation is barely flowing during combustion, improving the thermal efficiency, When the combustion is interrupted, the cold air is forced to turn into cooling, and the heat Up, there is no technical construction to stagnate high-temperature gas, and there is no function to heat low-temperature water in the bathtub, and if there is such a function, either heating function or hot water supply function is lacking today. It is the current state of the water heater or water heater industry.

A can body (1) to be described with reference to the drawings showing an embodiment of the present invention refers to all walls of a combustion chamber (8) and a heat absorption chamber (9), and a cylindrical wall has a cylindrical wall as shown in FIGS. 1 and 2. The mold wall divides into three parts, and the cylindrical wall has a notch in the mold. The pedestal (11) is fixed with a shield plate (18) described later in place and shielded by the can body (1) divided into three parts. It was fixed in place on the pedestal (11) so as to cover the plate (18), and the bent pieces of the shield plate (18) were also fixed together, and then covered with a lid-shaped wall except for the central upper part, to store hot water inside the mold-shaped wall. The upper wall of each can body is connected to the upper wall of the combustion chamber (8) as a part (19), a burner insertion port (1 ') is provided, and combustion gas flame does not directly touch the upper surface of the pedestal (11) at the lower part. As described above, the refractory heat insulating material (15) is laid up to the bottom surface on the upstream side of the heat absorption chamber (9), and the shield plate (18) is arranged in the heat absorption chamber (9) at regular intervals along the chamber wall. With rain and a magnified enlargement at the lower arc ends There is a bent piece, and the combustion gas is formed so as to flow upward and downstream in the endothermic chamber (9), which is loosely fitted and fixed to the lower endothermic chamber (9) side of the mold wall, downstream of the endothermic chamber (9). There are two cutouts for connection in the lower part of the side wall on the side, and the combustion gas passage has an L-shaped cross section.
(23) is a fan's splashing tubular body, and the lower part is a tubular shape whose lower end flat surface extends to the main side, and the main side arc matches the outer wall of the heat absorbing chamber (9) and connects two. The exhaust port (2
As shown in FIG. 1, the combustion gas from the burner tip (1 ″), which reaches 4), passes through as shown by the arrow. Although it is divided into directions and rises vertically, the combustion gas passages are L- and N-shaped merged as far as FIG. 1 shows.

The can body (2) has an inverted bottomed cylindrical shape with a large diameter in conformity with the can body (1) and is stacked at a required interval including the upper wall, but the can body (2) has a fixed position on the side wall. The water inlets (12) and (17) are the heating return port and the hot water outlet (21), and the connection fittings (20) for the heat-responsive switch.
Then, make a cutout for the combustion gas passage (23) so that the lower part of the side wall on the downstream side of the heat absorption chamber (9) is opened, and make a cutout for the burner insertion port (1 ') on the upper wall. Grip ((burner mounting circular seat (25) is attached after all can bodies are attached)) Overlay the can body (1) at a fixed position of the pedestal (11) and repair the cutout part. None, a water chamber (5) in which the upper part of the hot water storage part (19) communicates with the upper part of the water chamber (5) is obtained, and the inner water chamber is used for heating.

Like the can body (2), the can body (3) and the can body (4) have a shape of a cylinder with an inverted bottom, and each has a shape in which the diameter is increased to a necessary interval including the upper wall. For the burner insertion port (1 ') and the upper end for the combustion gas passage (23), and the side wall is equipped with the water inlet (16) for the water chamber (6) and the tap hole (22). Cut the heat-responsive switch (20) and the above-mentioned (12), (21), (17), and install both of them in a fixed position on the pedestal (11) so as to cover the can body (2). Then, the water chamber (6) is obtained and the intermediate water chamber is used for hot water supply.

On the outer wall surface of the can body (3), several stages of horseshoe-shaped guide plates (10) in which the upper flow path of the endothermic hot water for the water chamber (7) doubles as a fin are arranged, and the bottom of this water chamber is a pedestal. The guide plate (10) is partitioned by the same material at a position slightly above (11).

The required space of the can body (4) is determined by the guide plate (10), which is a side wall and an upper wall having a large diameter, and the upper wall has a burner insertion port (1 ') and a combustion gas passage (23). ) For the heat responsive switch (20) and (17) (21) (22) for the water supply port (13) and outlet (14) at the side wall. Body (3)
Is further overlapped so as to cover the notch and finishing of the notches and details to obtain the water chamber (7). Since the outer water chamber is used for circulating hot water and the side wall of the can body (4) is partitioned slightly above, the lower part of the can body (3) has a relatively low temperature, and the water supply port ( Efficient heat exchange can be achieved by providing water from above the side wall, which is more efficient in natural circulation than the provision of 13). The wall of this device has a quadruple structure as indicated by the can number.

From this point onward, it is assumed that all water inlets and outlets are connected and the burner (1 ″) is installed along with the heat-responsive switch (20) and the collective exhaust port (24) described later, and the water chamber (7) is filled with water. Only use hot water without heating or use only heating, and use hot water and heating at the same time, water chamber (7) is assumed not to be necessary, water chamber (5)
The water chamber (6) and the water chamber (6) have been supplied with water, and the burner tip (1 ″) is formed on the upper wall of the combustion chamber (8) and the upper can body (4) so that downward injection can be performed. When the dial of (20) is set to the set temperature and at the same time the heat of combustion gas is ignited, the combustion gas is shielded while heating the wall of the combustion chamber (8) and contacting the bottom wall of the hot water storage section (19) with the heat insulating material (15). By installing the plate (18), the upstream side wall of the heat absorption chamber (9) is heated to reach the upper space part which is open upward along the side wall, etc., and the heat efficiency into the water chamber (5) is obtained by the effects and effects described later. While heating the downstream side wall of the high heat absorption chamber (9), it is divided into two directions in the combustion gas passage (23), and it is possible to rush into the inside and heat the entire wall so that the heat absorption chamber is inside the water chamber (6).
Heat is exchanged next to (9) and reaches the collective exhaust port (24). Heating to the water chamber (6) is performed from all walls of the combustion gas passage (23) and all walls of the can body (2). Heat-responsive switch (2
When the set temperature of (0) is reached and combustion is interrupted, there is re-combustion due to natural cooling, but the time required to reach the above is relatively short, because the burner output is the same compared to the conventional hot water boiler. However, with the miniaturization, it is a wasteful water heater can body that heat efficiency is excellent and there is little loss of heat transfer action, and boiling more water than is necessary.

Combustion gas passages, which are indispensable for the can structure of the present invention, have some actions and effects due to the high, low and bending of the combustion chamber. (8) The combustion gas that passes through all walls while heating is a heat insulating material. While contacting with (15), the lower wall of the hot water storage part (19) is heated and at the same time guided by the shield plate (18), reaches the upper space while heating with the upstream side wall of the heat absorbing chamber (9) However, due to the interposition of the shield plate (18), recirculation stagnant is performed for a moment, and the heating in the water chamber (5) is instantaneous and continuous, so the amount of heat given to all walls of the upper space further increases and water The amount of heat exchange to the chamber (5) increases, and the combustion gas passage (2
There is a considerable amount of heat until it reaches the collective exhaust port (24) by splitting into two directions in 3), and the amount of heat exchange from all walls of the combustion gas passage (23) to the water chamber (6) is also large. It is a structure that is not found in the conventionally known hot water boiler exhaust stack, and when the combustion is interrupted during the combustion, a heat trapping function is obtained in the upper space by the interposition of the shielding plate (18), and the combustion gas heat At the same time that the upper space wall absorbs heat, the heat is automatically prevented from flowing out and the rate of spontaneous cooling is naturally slowed down, so that the re-combustion time interval can be maintained for a long time. For this reason, a short stack at the top of the collective exhaust port (24) can fully function. A description of the collective exhaust port (24) will be given later, but FIG.
The purpose is to unify the exhaust gas from both combustion gas passages as shown in FIG.

Conventionally known water heaters have been constructed with various techniques for forming various heat traps. For example, the upper part of the water heater is opened and an exhaust pipe is fitted inside the can body to prevent heat traps and recirculation. Although it is formed to obtain, it is possible to see the discoloration that seems to be damaging the material of the exhaust stack due to high temperature gas heat exhaust, rather than the structure where high heat contacts the exhaust stack like this. The exhaust pipe itself of the present invention has a heat exchange wall to improve the endothermic effect, and the combustion gas passage (23) can be incorporated inside the can body.

As shown in FIGS. 1 and 2, the water chambers interposed between the can bodies are in close contact with the can body walls, which are alternately adjacent to each other around the can body (1) wall, with warm water and fresh water. Wavy type heat transfer around the wall of the body (1)
If the heat of the hot water temperature in the water chamber (5) falls below the set temperature due to heat exchange to the water chamber (6) via the can body (2), the heat is generated by repeating the combustion by the operation of the heat responsive switch (20). Due to the exchange action, the hot water in the double water chamber reaches an appropriate temperature, and the hot water once reaching the set temperature naturally exchanges heat with each other as described above, thereby delaying the time of natural cooling.

If necessary, a part of the side wall of the combustion chamber (8) is opened to open the side wall of the can body (2) and the wall of the combustion chamber (8) is projected to directly burn the gas to the water chamber (6). It is also possible to give The guide plate (10), which also serves as the heat-absorbing fins, has a horseshoe shape on the outer wall surface of the can body (3) as described above and maintains a predetermined interval, and its central portion. Starting from the position indicated by the point, slightly above the water supply port (13) of the can body (4), the mounting is slightly inclined and the center part is 180 degrees from the second step.
The water inlet (1) has been installed by changing the direction and the water is supplied to the water chamber (7).
The water flowing in from 3) has the hot water heat in the water chamber (6) already transferred to the entire wall of the can body (3) and gradually undergoes heat exchange so that the hot water flow is formed by the guide plate (10) in the water chamber. The water continues to rise along the upper flow path while continuing to absorb heat, and at the same time heat is absorbed into the water that follows, flowing out from the upper tap hole (14) one after another and connecting to the bathtub to exchange heat in the bathtub by natural circulation. The water reaches the right temperature,
If forced circulation is performed using a pump, the time required for natural circulation is almost halved. In the case of the can body (3), the heat transfer amount of all walls increases significantly, and the amount of heat exchange increases. The upper flow path, which considers fluidity and slow control by the guide plate (10),
Since it is necessary to slowly control the flow rate of warm water in order to obtain the amount of warm water that is close to the optimum temperature so that heat can be exchanged with a larger amount of water, the contact time with the heat source inevitably becomes longer and the endothermic depth is deeper. The thicker the layer, the faster the heat absorption is shallow and the layer of heat of warm water is thin.

In the center of the upper part of the hot water storage part (19) inside the mold wall of the can body (1), a heat responsive switch (20) for controlling the rise and fall of the hot water temperature to a set value is installed, and together with the can body of this invention, a water heater is manufactured. It is an important component that is indispensable for this. A shield plate (18) inside the can body next to the parts
The supplementary explanation is that it is loosely fitted and fixed on page 2 above, and it is the bent piece that is fixed, and the upper arc ends are not fixed, but arcs are provided to ease expansion due to combustion gas heat. Both ends are made of heat-resistant material with a large gap between it and the mold wall.

In the can body of this invention, the low temperature water used for heating enters the water chamber (5) from the heating return port (17) in the water chamber (5) during winter heating, and the heat responsive switch (20) is activated. On the other hand, there is a concern that the hot water temperature in the water chamber (6) is small and the hot water temperature rises excessively when it is not used. However, even if the hot water temperature rises, On the contrary, the hot water heat in the water chamber (6) prevents the temperature rise of the hot water in the water chamber (5) from the whole wall of the can body (2), and as described in the front leaf, the can in the water chamber (7). The heat of the hot water in the water chamber (6) is naturally exchanged through the wall to the inner and outer water chambers by the low temperature water that is heat-exchanged through all the walls of the body (3), and The fear of excess rise disappears.

When using the can body of this invention, the water chamber (5) is for heating, the water chamber (6) is for hot water supply, and the two water chambers are for simultaneous heating. Both heating and hot water supply can be used independently, and of course at the same time. It can also be used, and the water chamber (7) is for circulating boiling water, and it has a structure that does not interfere with entering water, but if there is a connection with the bathtub by utilizing the heat dissipation of the hot water heat inside the can body (3) The most effective use is to keep the water flowing from the circulation outlet in the bathtub to the top.
Since the low-temperature water is in close contact with the walls of each can body, the effect of heat transfer does not follow that of other water heaters. There is no heat loss other than known.

An embodiment of this invention will be described with reference to the drawings. The water chamber (5) has a water supply port, assuming that the various pipes and equipment leading to the can are already installed.
Water is supplied from (12) to the water chamber (6) through the water inlet (16), and water is supplied to the bathtub in the water chamber (7) by using another water tap to maintain the water level above the circulating tap and fill each with water. After that, a heat-responsive switch
The hot water temperature is set by the dial of (20) and the burner (1 ″) is ignited at the same time, while heating the wall of the combustion chamber (8) and contacting the heat insulating material (15), the lower wall of the hot water storage part (19) absorbs heat. Combustion gas rushes into the chamber (9), and the shield plate (18) is installed to reach the upper space along the upstream side wall as shown by the arrow, and reach the upper wall,
While heating the side wall of the combustion gas on the side wall, the combustion gas flows downstream along the wall on the downstream side and is divided into two directions in the L-shaped combustion gas passage (23) to heat the entire wall. Combustion gas injected from the burner (1 ″) through the exhaust outlet (24) as shown by the arrow in FIG. 1 passes through the wall of the combustion chamber (8) and the heat absorption chamber (9). When the combustion gas is heated, heat exchange is performed on all walls of the combustion gas passage (23), and when a temperature difference between the water temperature in the water chamber (5) and the water temperature in the outer peripheral water chamber (6) reaching the wall begins to occur, The hot water heat in the water chamber (5) naturally exchanges heat to the low temperature water in the water chamber (6) on all walls of the can body (2), during which combustion is continued and the hot water storage section in the water chamber (5) is continued.
(19) When the set temperature of the heat responsive switch (20) provided at the center of the upper part is reached, the operation temporarily interrupts the combustion of the burner (1 ″), but the water chamber (6) keeps the amount of hot water. It has a large endothermic coefficient and is also a heat source for exchanging heat to the water chamber (7), and the degree of heat absorption increases, and both combustions are repeated due to the decrease in hot water heat, while of course supplying hot water and heating water. The hot water in each water chamber exchanges heat with all the walls adjacent to the inside and outside, and the temperature of the hot water in the bath reaches a suitable temperature by natural circulation.

The high, low, bending and shielding plates (18) of the combustion gas passage in the can body of the present invention are used to continuously heat the recirculation pool of the combustion gas to the upper space wall of the heat absorption chamber (9). In order to improve the thermal efficiency of the hot water in the chamber (5), when the combustion is interrupted, the shield plate is provided in the upper space of the heat absorbing chamber (9) due to the high, low and bending.
Due to the interposition of (18), there is a stagnation of high temperature gas and a heat trap state is obtained to automatically prevent the outflow of gas heat and slow down the rate of natural cooling, so that the re-combustion time interval can be kept as long as possible. In other water heaters, of course, the heat of the exhaust gas that is naturally released to the atmosphere is disposed as a combustion gas passage in the water chamber (6) inside the can body to absorb the heat on all walls of the water chamber (6). In addition to increasing the heat efficiency to hot water, it also promotes appropriate temperature rapidly and serves as a heat exchange heat source to the outer peripheral water chamber (7) that extends to the wall. This can body does not need to raise the hot water temperature to a high temperature, so it can be distinguished. By doing so, each function can be fully exerted with the setting value of the medium temperature heat responsive switch (20), and the hot water temperature used for floor heating, which is considered the highest peak of modern heating, is the medium temperature pointed out by this invention. Cold that often has little adverse effect on the can body, can withstand long-term use and saves fuel consumption In this case, this can body has a heating water chamber, a can body equipped with a water chamber in which an antifreeze solution can be used in the pipeline leading to the water chamber, and it is smaller than the conventional water heater and it wasted to boil more water than necessary. This one can has three dedicated water chambers, it can be adjusted in ordinary households, it can be used for large-capacity business if necessary, the structure is simple, it is easy to mass-produce and it is easy to manufacture and the cost is low. By subjecting the entire surface of the can to a surface treatment after completion of the can manufacturing process, the water resistance and durability are excellent, and its practical value is great.
