Description

[Detailed description of the invention] This invention meets one of the modern social demands by effectively utilizing waste heat from the incineration of dust, which is emitted in large quantities in ordinary households, as thermal energy for heating baths. The present invention relates to a technology that aims to achieve certain energy savings and rationalization of dust treatment all at once, that is, a bath-fired kettle that utilizes heat from dust incineration.

However, in order to use the exhaust heat from incinerating dust in a dust heat generator to heat a bath, it is not enough to simply connect the dust incinerator and the bath fire pot so that their internal combustion chambers communicate with each other. It has been difficult to realize this because of the following drawbacks.

That is, when dust is incinerated, a large amount of soot, embers, etc. are normally generated, and therefore, in order to utilize the heat of dust incineration, the dust incinerator and the bath-fired kettle are connected to each other. The combustion device in the firing pot becomes clogged with soot, embers, etc., resulting in poor combustion, resulting in an inconvenience.

Furthermore, if the dust incinerator and the bath-burning pot are simply connected, the combustion heat will escape to the dust incinerator and cause a large heat loss when the bath is lit using the combustion device of the bath-burning pot. There is also the inconvenience that this occurs.

The present invention has been developed in view of the above points, and its purpose is to effectively utilize the exhaust heat during dust incineration, and to prevent the soot, embers, etc. generated during dust incineration from burning the bath. To provide a bath-fired pot that utilizes heat from dust incineration, which can suppress as much as possible the inconvenience of clogging of an in-cooker combustion device, and which has little loss of combustion heat due to the bath-fired in-cooker combustion device; The objective is to realize this with the simplest possible configuration.

In order to achieve the above object, the bath-burning pot using heat from dust incineration according to the present invention has a bath-burning pot equipped with a heat exchanger in the upper part and a combustion device in the lower part, and a dust incinerator. , the partition wall between the dust incinerator and the bath heating pot includes:
A first position where both internal combustion chambers are disconnected from each other and a second position where the combustion chambers are communicated with each other while covering the upper part of the combustion device in the lower part of the bath firing pot. It features a damper that can be switched freely.

The above characteristic configuration provides the following excellent effects.

That is, when the dust incineration heat from the dust incinerator is used as heat for heating a bath, the damper is placed in the second position so that the dust incineration is performed while covering the upper part of the lower combustion device in the bath firing pot. Since the exhaust air from the oven can be guided to the upper heat exchanger inside the bath firing oven, even if a large amount of soot and embers are generated due to dust incineration, they will be blocked by the damper and will not fall on the combustion equipment. Therefore, the exhaust heat from dust incineration can be effectively used as energy for heating a bath, while clogging of the combustion device can be effectively prevented.

In addition, when the button is pressed in this state, the soot, embers, etc. that have accumulated on the damper are discharged to the combustion chamber side of the dust incinerator when the damper is switched to the first position, so that the combustion inside the bath-fired pot is prevented. There's nothing left in the room.

On the other hand, when heating a bath using only the in-bath combustion device without using the dust incineration heat, by positioning the damper in the first position, the separation between the bath heating cauldron and the dust incinerator is Since communication between the combustion chambers can be completely shut off, heat loss due to combustion heat from the combustion device escaping to the dust incinerator side does not occur.

As described above, according to the present invention, by properly installing a damper with an extremely simple structure at a joint position, a convenient and useful bath-fired pot using heat from dust incineration can be created that fully achieves the intended purpose. I was able to obtain it.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

1 is a dust incinerator, which has a combustion chamber 8 having a grate 7 at the bottom and a dust inlet 9 which can be opened and closed at the top;
An ash outlet 1 formed at the bottom of the fire grate 7 and which can be opened and closed freely.
Although a general-purpose type consisting of an incineration ash storage chamber 11 having an incineration ash storage chamber 11 having 0 is shown in the figure, any other structural form may be used.

Reference numeral 2 denotes a bath heating pot that is integrally connected to the side (back) of the dust incinerator 1, and is equipped with a combustion device 5 such as a gas burner in the lower part of the combustion chamber 12, and has a combustion device 5 such as a gas burner in the lower part of the combustion chamber 12. In addition, a heat exchanger 4 consisting of a jacket 4a, a fin tube 4b, and an exhaust flue 4c for forcibly circulating bath water in the bathtub 13 via a pump 14 and circulation piping 15 is provided.
It is equipped with

Therefore, the partition wall 3 between the dust incinerator 1 and the bath-fired pot 2 is designed to block the internal combustion chambers 8 and 12 of both 1 and 2 from communicating with each other, so that when the bath-fired pot 2 is used, Internal combustion of both 1 and 2 at a first position where the high-temperature combustion exhaust of the combustion device 5 can be discharged to the atmosphere through the heat exchanger 4, and in a state where the upper part of the combustion device 5 in the bath-fired pot is covered. Room 8,
12 are connected to each other, and the exhaust gas during dust incineration is connected to the bath-burning pot 2.
A damper 6 is provided which is alternatively switchable between a second position and a second position which allows exhaust through the heat exchanger 4 to the atmosphere.

In addition, 6a in the figure is a screen provided on the partition wall 3, and has the role of preventing incinerated materials from accidentally entering the combustion chamber 12 when the dust incineration exhaust gas is used as thermal energy for heating a bath. .

Reference numeral 16 denotes a bath water replenishment valve, and if this is installed, on-off valves 16a are provided at the suction and discharge portions of the bath water circulation pipe 15 from the bathtub 13, respectively.

16b, and by closing the valve 16a on the suction side and opening the valve 16b on the discharge side, hot water for hot water or hot water for washing can be freely obtained.

Further, 1T is an auxiliary combustion burner for dust incineration that is integrally connected to the combustion device 5 of the bath-fired pot 2, and facilitates ignition when incinerating things that are difficult to ignite initially, such as dust with a high moisture content. be able to.

Moreover, 19 is an opening/closing lid provided at the exhaust outlet when used only for dust incineration.
