Description

TECHNICAL FIELD The present invention relates to a heating addition device capable of improving heating efficiency by adding heat to a heat source for heating.

On cold days, various heating devices such as stoves, fan heaters, and air conditioners are necessary for maintaining workability and health.
Various heating devices are known, for example, those described in Patent Documents 1 to 3.

The waste oil stove described in Patent Document 1 is disposed in an outer pot and an outer pot in a substantially sealed state, burns the supplied waste oil, and exhausts the smoke from the stove to the outside through a smoke exhaust duct. A combustion part equipped with a kettle, a circulating blower part that circulates the air in the room to be heated in the space between the outer kettle and the inner kettle as a heating space, a fuel supply part that supplies a predetermined amount of waste oil to the inner kettle, and waste oil and a combustion air supply unit for supplying combustion air necessary for burning the fuel.

The heating device with an air purification function described in Patent Document 2 is heated by a heating device casing having an air introduction part in the lower part and an air outlet part in the upper part in the installed state, and a heat source on the inside lower side. An indoor air ascending space through which the indoor air flows is formed between the reaction cylinder and the platinum catalyst holder provided on the inner upper side so that the ascending heated air comes into contact with and passes through. In this heating device, the air that enters the reaction cylinder via the heat source from the air inlet and rises and comes into contact with and passes through the platinum catalyst holder passes through the room air rising space in the heating device casing. of air is drawn in, merged with the air, and led out from the air lead-out portion.

The air supply filter described in Patent Document 3 and the combustion device to which it is attached include an air supply port that takes in combustion air, an air supply passage that sends the combustion air taken in from this air supply port to the burner, and an air supply The air supply filter comprises a partition plate provided in the air passage for meandering the combustion air to capture dust contained in the combustion air, and a drain cock for removing the captured dust. .

Japanese Patent No. 3722226 JP 2010-197032 A JP-A-11-182838

However, in the waste oil stove described in Patent Document 1, the waste oil is burned in the inner pot and the flue gas is discharged outdoors through the smoke exhaust duct, and the heating space between the outer pot and the inner pot is provided by the circulation blower. The air in the room to be heated is circulated and sent to the heating space. Therefore, the combustion in the inner pot does not contribute to indoor heating except for heating the inner pot itself, and the heating space between the outer pot and the inner pot is just a space, so heat is heated by the heat emitted from the inner pot. Since the space is heated, the efficiency is poor, and the heating temperature of the heating space is immediately discharged to the heating space by blowing air, so a high temperature cannot be expected.

In the heating device having an air purification function described in Patent Document 2, it is stated that the platinum catalyst support may be a metallic scrubber-like or spongy-like metal or ceramic surface having an air vent and platinum supported thereon. However, it is for purifying the heated air, not for improving the heating efficiency.

Furthermore, in the air supply filter described in Patent Document 3 and the combustion apparatus to which it is attached, a metal scrubber (air advancing direction diffusing means) is provided in the air supply passage that is formed by the partition plate and causes the combustion air to meander. This metal scrubber is for diffusing the traveling direction of the combustion air passing through the air supply passage and capturing dust contained in the combustion air.

With only a heating system, the space that can be heated is limited, and high efficiency cannot be expected. There is a demand for a heating addition device that can heat another space by supplying it to another space.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a heating additional device capable of heating not only a space heated by a heat source but also other spaces with high-temperature air.

The additional heating device of the present invention includes a storage chamber heated by a heat source that heats a first space, a plurality of intertwined thin metal wires housed in the storage chamber, and hot air emitted from the storage chamber to the second space. and an air blower that blows hot air from the thin metal wire to the piping by blowing air into the storage chamber.

According to the additional heating device of the present invention, the heat source heats the first space. In addition, heat is accumulated by heating the thin metal wire in the storage chamber by the heat source. Then, when the air from the air blower flows into the storage chamber, the fine metal wires release heat and become hot air, which is discharged into the second space through the pipe.

The thin metal wire may be stored in contact with an inner wall surface of the storage chamber on the heat source side.
When the inner wall surface on the heat source side is heated by the heat source, the thin metal wire in contact with the inner wall surface is heated by heat transfer, so that the thin metal wire can be efficiently heated.

The fine metal wire may be formed by a metal scrubbing brush. Metal scrubbing brushes have moderate elasticity, resistance to heat, high thermal conductivity, and air permeability. Can be heated by air blast.

A return wall for receiving and retaining the blown air may be provided in the air passage of the storage chamber, and the thin metal wire may be arranged upstream of the return wall in the air passage . Since the return wall for receiving air is installed in the air passage, warm air stays in the air passage and heats the fine metal wires. Therefore, the thin metal wire can be heated to a higher temperature.

The housing chamber may be formed by an outer peripheral surface of a combustion chamber of the heating device serving as the heat source, and an outer jacket portion surrounding a portion of the heating device. Further, the accommodation chamber may be formed by an outer peripheral surface of an exhaust pipe of a heating device, which serves as the heat source, and a jacket portion that surrounds a portion of the exhaust pipe.

According to the additional heating device of the present invention, the first space is heated by the heat source, and the second space is also heated by the heated thin metal wires, and hot air is emitted from the piping. However, other spaces can also be heated with hot air.

(Embodiment 1)
A heating addition device according to Embodiment 1 of the present invention will be described with reference to the drawings.
First, the heating device will be described as an example of a waste oil stove.
The waste oil stove 100 shown in FIG. 1(A) is mounted on a trolley C to facilitate movement with the additional heating device 10 added, and heats a first space such as a workshop.

The waste oil stove 100 includes a cylindrical main body 110 having a combustion chamber inside, a saucer 120 provided at the bottom of the main body 110 for storing waste oil, a fuel supply section 130 supplying the waste oil to the saucer 120, and a stove main body. A blower 140 for blowing air into 110 and an exhaust pipe 150 are provided.

A lid 110c is provided on the upper end 110e of the body portion 110. As shown in FIG.
An inspection opening 111 is formed in the lower portion 110b of the main body portion 110 for looking into the tray 120 at the bottom.
An air supply pipe 112 extending downward from an upper portion 110u of the body portion 110 is arranged in the body portion 110 . An air outlet is formed in the air supply pipe 112 , and the air from the air blower 140 is blown into the main body 110 .

A partition plate 113 that partitions the internal space in the vertical direction is arranged on the upper portion 110u of the main body portion 110 . A through hole 113a is formed in the partition plate 113 along the circumferential direction. A guide pipe 113b extending obliquely downward is formed in the through hole 113a.
A fence 114 is provided around the upper portion 110u of the body portion 110 for protection.

The receiving tray 120 burns the waste oil (fuel) dripped from the fuel supply section 130 .
The fuel supply unit 130 includes a tank 131 for storing waste oil, a sub-tank 132 for temporarily storing the waste oil from the tank 131 and adjusting the flow rate of the waste oil supplied to the receiving pan 120, and a receiving pan 120 for receiving the waste oil from the sub-tank 132. It is provided with a supply pipe 133 that supplies to.

The blower 140 blows air to the air supply pipe 112 of the waste oil stove 100 and to the additional heating device 10 . The blower device 140 includes a blower 141 that is a source of heat generation, an introduction pipe 142 that connects the airflow passage of the blower 141 and the airflow passage of the additional heating device 10 , and a connection that extends from the introduction portion and is connected to the upper portion of the air supply pipe 112 . a tube 143;
Air blower 141 can be a blower.

Exhaust pipe 150 is a chimney attached to extend upward from the upper portion of main body 110 . A disc-shaped ceramic 151 can be arranged in the exhaust pipe 150 for dust removal.

Next, the configuration of the additional heating device 10 attached to the waste oil stove 100 will be described.
The additional heating device 10 includes a mantle portion 11 that surrounds a body portion 110t that is a part of the main body portion 110 and that is an accommodation chamber 11s between itself and the main body portion 110, and a heating pipe 12 that penetrates the body portion 110t of the main body portion 110. , a duct 13 extending from a position opposite to the connection position with the introduction pipe 142 , a thin metal wire 14 housed in the jacket 11 , and a blower 140 .

The outer jacket 11 closes a cylindrical portion 11c formed along the outer peripheral surface of the trunk portion 110t of the main body portion 110, and an upper opening and a lower opening between the cylindrical portion 11c and the trunk portion 110t of the main body portion 110. and a doughnut-shaped closing plate 11b.
The space between the mantle part 11 and the main body part 110 is an air passage through which the air from the blower 140 is blown, and also functions as the storage chamber 11s.
The heating pipe 12 is arranged so as to communicate the blowing passages on the blower 141 side and the duct 13 side.
The duct 13 is a pipe that extends to another space (second space) different from the first space heated by the waste oil stove 100 and discharges warm air.

The hot air may be discharged from the duct 13 as it is, but a circulator 13s is installed at the opening of the duct 13 to allow the hot air to reach far away from the second space or to circulate in the second space. You can also Also, if the duct 13 is directed upward, the warm air becomes an ascending current, spreads along the ceiling, and can heat a wider area.

The blower device 140 is commonly used by the waste oil stove 100 and the additional heating device 10 .
Although the blower 140 is shared in this embodiment, it is also possible to provide blowers individually.

Here, the thin metal wires 14 arranged in the storage chamber 11s between the jacket portion 11 and the main body portion 110, and the heating tube 12 will be described with reference to FIG. 1(B).
The thin metal wires 14 are collected so that a plurality of wires are intertwined. The fine metal wire 14 can be, for example, a rounded metal scrubbing brush. Moreover, the metal thin wire 14 can be made of stainless wool.
The thin metal wires 14 have elasticity when gathered together, and are housed in a contracted and deformed state by being pushed into the housing chamber 11s. Therefore, the thin metal wire 14 is accommodated while being pressed broadly against the outer peripheral surface of the body portion 110 (the inner wall surface of the accommodation chamber 11s) on the heat source side.

A usage state of heating addition device 10 according to Embodiment 1 of the present invention configured as described above will be described with reference to the drawings.
As shown in FIG. 1A , in the waste oil stove 100 , when fuel is supplied from the fuel supply unit 130 to the pan 120 and burned, the combustion heats the heating tube 12 and heats the main body 110 . By doing so, heat is radiated from the upper portion 110u and the lower portion 110b of the body portion 110 exposed from the additional heating device 10, so that the surrounding space (first space) in which the waste oil stove 100 is installed is heated.

As shown in FIG. 1B, the thin metal wires 14 accommodated in the accommodation chamber 11s are heated by heating the main body 110 . In particular, since the fine metal wire 14 is in contact with the outer peripheral surface of the body portion 110 while being pressed, it is heated by heat transfer from the body portion 110 .
Therefore, heat is transferred from the main body portion 110 to the thin metal wire 14 , so that the thin metal wire 14 accumulates heat.

As shown in FIG. 1A, the air blown from the blower 141 passes through the introduction pipe 142, flows into the storage chamber 11s and the heating pipe 12, and flows along the outer peripheral surface of the main body portion 110 and the heating pipe 12. .
The air that has flowed into the storage chamber 11s and the heating pipe 12 is heated by heat radiation from the metal thin wire 14 (see FIG. 1B), and passes through the duct 13 to the place where the waste oil stove 100 is installed (No. 1 space) is released to another place (second space).
Since the fine metal wires 14 are lumps of fine wires gathered together, there are sufficient gaps for air to pass through. Therefore, the air blown from the air blower 141 can pass through the storage chamber 11s while contacting the thin metal wire 14 and being heated.

In this manner, not only the installation location (first space) heated by the waste oil stove 100 but also a different location (second space) can be heated by the additional heating device 10 . In addition, since the thin metal wire 14 is housed in the housing chamber 11s of the additional heating device 10, the thin metal wire 14 accumulates heat from the waste oil stove 100 and heats the air blown from the blower 141, so that the hot air discharged from the duct 13 can be heated to high temperatures.

For example, when the thin metal wire 14 is placed apart from the outer peripheral surface of the main body 110 , the air in the storage chamber is heated by heat radiation from the main body 110 , and the heated air heats the thin metal wire 14 . Therefore, the fine metal wire 14 is heated through air.
However, in this embodiment, even if the fine metal wire 14 formed by the metal scrubbing brush is pushed into the storage chamber 11s while being contracted and deformed, ventilation can be ensured. Therefore, by bringing the thin metal wire 14 into contact with the main body 110 , it can be heated directly from the main body 110 by heat transfer. Therefore, the thin metal wires 14 can be efficiently heated, and the heating efficiency can be improved.

Furthermore, the air blown from the blower 141 is heated by the heating pipe 12 by flowing into the heating pipe 12 through the introduction pipe 142 , flows into the storage chamber 11 s, and is discharged through the duct 13 . Therefore, it can be heated to a higher temperature.

In addition, since the blower 140 is commonly used for the waste oil stove 100 and the additional heating device 10, the number of components of the additional heating device 10 can be reduced and the size can be reduced.

The additional heating device 10A is arranged in an opening 201 at the upper end of the metal can 200. As shown in FIG.

The additional heating device 10A includes an air blower 140A, a body portion 15 to which a connection pipe 144 from the air blower 140A is connected, and an accommodation chamber 15s formed therein, and a duct 13 extending from the body portion 15.
The body portion 15 is formed in a thin box shape. The thin metal wire 14 is accommodated in the accommodation chamber 15s of the main body 15, as in the first embodiment. The thin metal wire 14 is sandwiched between the inner wall surfaces of the body portion 15 and is in contact with them while being pressed.
Duct 13 is formed to extend to a second space different from the location (first space) where metal can 200 is installed.

By forming the additional heating device 10A according to the second embodiment in this way, when the firewood is burned, the surroundings of the metal can 200 are heated, and the main body portion 15 is heated and stored in the storage chamber 15s. The thin metal wire 14 thus formed is heated by heat transfer and accumulates heat.
The air blown from the air blower 140A passes through the housing chamber 15s and flows from the duct 13 to the second space. The blown air is heated by heat radiation from the fine metal wires 14 when passing through the housing chamber 15 s , and is discharged from the duct 13 as high-temperature air.
Even if the metal can 200 burning firewood is used as the heat source in this manner, the same effect as in the first embodiment can be obtained.

(Embodiment 3)
A heating addition device according to Embodiment 3 of the present invention will be described with reference to the drawings.
In the third embodiment, a wood stove is used as the heat source, and a housing chamber for the additional heating device is provided so as to partially surround the chimney.
As shown in FIG. 3, the wood stove 300 includes a main body 310 having a combustion chamber for burning firewood and a chimney 320 for discharging smoke from the main body 310 to the outside.

By surrounding the outer peripheral surface 321 of the chimney 320, the additional heating device 10B includes the mantle portion 16 whose inside is a storage chamber, the air blower 140A that blows air to the mantle portion 16, and a room (second space) adjacent to the mantle portion 16. ) and a duct 13 extending to the
A thin metal wire is accommodated in the accommodation chamber 16s between the jacket 16 and the outer peripheral surface 321 of the chimney 320, as in the first and second embodiments.
The fine metal wire is housed in a contracted and deformed state as if pressed between the jacket 16 and the outer peripheral surface 321 of the chimney 320 .

Since the additional heating device 10B according to Embodiment 3 is formed in this way, when firewood is burned by the wood stove 300, the surroundings of the wood stove 300 are heated, and the chimney 320 is heated. , the thin metal wire accommodated in the accommodation chamber in the mantle 16 is heated by heat transfer and accumulates heat.
The air blown from the air blower 140A passes through the storage chamber 16s via the connecting pipe 144 and flows from the duct 13 to the adjacent room. The blown air is heated by the heat radiated from the fine metal wires when passing through the accommodation chamber, and is discharged from the duct 13 as high-temperature air.
Even if the heat source is the wood stove 300 in this way, the same effects as in the first and second embodiments can be obtained.

(Embodiment 4)
A heating addition device according to Embodiment 4 of the present invention will be described with reference to the drawings.
In Embodiment 4, a modification of the main body portion in which a storage chamber for storing the thin metal wire is formed will be described.

As shown in FIG. 4, the body portion 17 is provided with a partition wall 17w that partitions the storage chamber 17s and causes the airflow path to meander. The partition wall 17w is provided with a return wall 17r having a concave portion facing upstream in order to retain air. A thin metal wire 14 is arranged on the upstream side of the return wall 17r in the air passage .

Since the return wall 17 r for receiving air is installed in the air passage, warm air stays in the air passage and heats the fine metal wire 14 . Therefore, the fine metal wire 14 can be heated to a higher temperature.
In addition, since the rectifying plate 17n in which the plate members are arranged in parallel is arranged at the folded portion 17m of the meandering airflow path, the warm air reaching the folded portion 17m can be smoothly folded back.

The return wall 17r whose recess faces the upstream direction can be, for example, as shown in FIGS. 5(A) and 5(B).
A return wall 17q shown in FIG. 5(A) is formed by bending a metal plate into a V shape that opens in the upstream direction.
Even if the return wall 17q is formed in this way, the hot air can be retained more efficiently than when a simple flat plate is arranged.

A return wall 17t shown in FIG. 5(B) is formed by forming ventilation holes in a metal plate whose height is adjusted so as to block the air passage. Therefore, the return wall 17t can flow hot air that has been heated by the ventilation holes while obstructing passage of hot air.
