Description

[Detailed description of the invention] This invention relates to an improved structure of an outside-fired bath that uses solid materials such as firewood as fuel.

Due to the recent economic situation of oil shortages, there is a growing momentum to once again utilize natural solid fuels such as firewood as an energy measure in various fields. The same applies to baths used in ordinary homes.

Outdoor-fired baths that use solid fuel such as firewood have existed for quite some time, but they were either of the type where the bath pot itself was exposed inside the built-in bathtub, or they were of the type called Goemon. An excellent primitive bath of the type called a bath or Choshu bath, which forms a bathtub independent of the modern gas-fired or oil-fired bathtubs. I couldn't see it.

On the other hand, even though gas-fired and oil-fired kettles are structurally superior, external-fired ones have the entire kettle installed outside the bathroom, which creates inconveniences in terms of space utilization, especially when it comes to the back door. When installed, it was common for most of the functions of the back door to be taken away. Therefore, in order to cope with these situations, this invention has developed and completed an outdoor heating type bath as described in detail below.

As can be understood from the longitudinal cross-sectional views shown in Figures 1 and 2, the bath kettle that constitutes this invention is basically formed by a combustion kettle and a water boiling case that houses and integrates the kettle inside. Ru.

In the combustion pot, a long combustion chamber 2 is formed in the horizontal direction from the fire spout 1, rising from the innermost part of the combustion chamber 2 and connected to an exhaust gas induction chamber 3 facing in the direction of the fire spout 1, which is formed above the fire spout 1. It consists of a series of flues that reach a soot cleaning port 4. Smoke exhaust induction room 3
are formed parallel to each other at a predetermined distance above the combustion chamber 2, and above the soot cleaning port 4, a smoke exhaust control valve 6 is connected.
It is connected to the smoke exhaust stack 5 via. In addition, a rostle 21 is installed on the bottom surface of the combustion chamber 2 next to the fire port 1,
It is divided into an ash basin 22 which also serves as an air intake. An opening/closing lid 11 with a weather vane 12 is provided on the front side of the fire pit 1.

The combustion pot formed as described above is housed and integrated within the water boiler casing 7 with the side surface beside the fire spout 1 exposed. At this time, a predetermined gap is maintained between the outer periphery of the combustion pot and the inner circumferential wall of the water boiler casing 7, so as to form a space that will become a water boiling chamber. If there is, a water pipe 71 communicating with the same space is arranged in the combustion chamber 2. On the other hand, the housing frame 72 on the outside bottom of the water boiler housing 7 has support legs 73, 73 which also serve as height adjustment.
...... is firmly attached to form an external heating bath pot.
In the illustrated embodiment, a gas burner or oil burner 2 is installed as an auxiliary combustion device in the combustion chamber.
3 to assist in the ignition of solid fuel,
In some cases, gas or oil can be used as auxiliary fuel when the solid fuel runs out, but this can of course be omitted. In the figure, 74 indicates a drain plug.

In order to realize an externally fired bath using this externally fired bath kettle, a cave that is located beside the bathtub B in the bathroom shown in the perspective view of FIG. 4th to 6th in the storage place S of
The external heating bathtub must be placed as shown in the diagram. That is, the outdoor-fired bath kettle is spatially isolated from the bathroom, and after installing and fixing guide rails S1, S1 in a cave-like installation area S close to the bathtub B, supporting legs are placed on the guide rails S1, S1. Place 73, 73... and install it by sliding it in as if pushing it in. After installation, if the bathtub is not in a good condition, slide it out again, adjust the height of each support leg 73, 73, and then install it as described above.
After the bathtub is installed as specified, the bathtub and the bathtub B are connected through transparent or translucent circulation pipes 8, 8, and the smoke exhaust pipe 5 is set up as specified. In the case where an auxiliary combustion device 23 is also provided, by connecting the auxiliary fuel supply pipe 9 to the connection nozzle 24, the external firing type bath of this invention is completed.

The outside-fired bath of this invention, which is constructed as described above, first has a structure in which the bath pot has a depth in the horizontal direction from the opening, which is extremely convenient for burning solid fuel such as firewood, and furthermore, The combustion opening, soot cleaning opening, smoke exhaust control valve, and ash storage opening are all centrally formed on the same side, providing excellent operability. In addition, since the long combustion chamber and the smoke induction chamber extending from the innermost part to the soot cleaning port are arranged vertically in parallel with a predetermined gap, the combustion chamber is Although it is compact, a large amount of its outer surface comes into contact with water, increasing the efficiency of boiling water and saving fuel. Also, because of this overall deep structure, it would normally be a dead space in the bathroom, or
The space next to the bathtub, which is only useful as a place to install an exposed conventional bath kettle in the bathroom, can be turned into a cave-like space separated from the rest of the bathroom and used as a place to install the bath kettle. Because of this, the area that protrudes from the installation area of this bath kettle is extremely small, which is not only very advantageous when the back door is also used as a fire pit, but also allows the front of the fire pit to be made wider. Since it is used, solid fuel replenishment operations can also be made smoother. In addition, when it comes to using the space inside the bathroom, instead of a dead space or an unsightly bathtub, it can be used as an neatly divided shelf-like space, making it possible to create a clean and spacious bathroom. . In addition, since the bathtub is installed in a location completely isolated from the bathroom, it is naturally not exposed to hot water, making it highly durable, and it is also easy to manage repairs in the unlikely event of a breakdown. It has many excellent features, such as being able to be easily carried out from the outside.

Furthermore, an especially excellent effect is that the slightly protruding side of the bathtub is used to connect the bathtub with a transparent circulation pipe that is exposed to the side of the fire pit. It must be mentioned that the water level in the bathtub can be checked directly from the fire spout before starting the fire, and empty heating can be completely prevented. Normally, complicated and expensive parts such as sensors must be employed for this purpose, but this invention does not require such components at all, and it is possible to realize a reliable bath at a correspondingly low cost.
