Description

Technical Field

The present invention relates to a regenerative fireplace boiler and, more particularly, to a regenerative fireplace boiler that can be used as both a fireplace and a boiler by connecting a hot water pipe to the fireplace, whereby the regenerative fireplace boiler can humidify the interior of a space, and has a grill to roast sweet potatoes, etc., whereby it can be used for various purposes.

Background Art

In general, a fireplace is a kind of heating apparatus that is formed in the interior wall of a building, for example the wall of a living room of a house, and heats the interior in winter by emitting to the interior heat generated by burning solid fuel such as firewood to the interior.
Fireplaces have various and unique designs, so they are used as an interior decorative structure in a room in other seasons except winter.
Further, the other portion except the frame of a door disposed ahead of a combustion chamber of a fireplace is made of transparent glass such as reinforced glass so that the combustion state of firewood or fuel in the combustion chamber can be visually exposed to the outside.
On the other hand, a boiler system, which is an apparatus for heating and supplying hot water using oil, electricity, and gas, etc. as fuel, heats water up to predetermined temperature and supplies the hot water through a supply line so that the hot water heats an interior space and is then circulated by a circulation pump. The boiler system heats interior air and supplies hot water at home, so it is in close connection with our life.
Accordingly, many combinations of a fireplace and a boiler system have been proposed, these combinations provide heating circulation systems by installing heat collection parts of a boiler system such as a water pipe and a container in the parts of a fireplace, and the heating circulation systems have little different configurations.
For example, Korean Patent No. 10-1192840 has proposed a 'Fire place with a boiler', which includes a combustion chamber and a main body having a stove pipe over the combustion chamber, in which a door is coupled to the front side of the main body to put solid fuel into the combustion chamber. Further, an ash pan is disposed under the main body to collect and take out ashes remaining after the solid fuel is burned, and an inner pipe spirally wound and spaced from an inner wall are connected to the combustion chamber, with a first end is connected to an inlet pipe fixed outside the main body and a second end connected to an outlet pipe fixed outside the main body.
This configuration used a both a fireplace and a boiler system by supplying hot water for heating the interior using the heat source of a fireplace.
However, the configuration is used as a fireplace and a boiler system, but is not given any additional configuration, so spatial usability is low.
Further, there is a need for a humidifier to maintain interior humidity in winter, but the fireplaces of the related art have no humidifying unit, so it is required to separately purchase and install a humidifier. Accordingly, the entire cost is increased and spatial usability is deteriorated because the separate humidifier occupies a predetermined area in a small interior space.

Hereinafter, regenerative fireplace boilers according to embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in the figures, a regenerative fireplace boiler of the present invention includes a main combustion chamber 10, an interior fuel intake 20, a hot water circulation pipe 30, a hot air circulation pipe 40, an exterior port 50, a damper adjuster 60, and an ash shield 70.
The main combustion chamber 10 is disposed at an outdoor side 1, has a first combustion chamber 12 and a second combustion chamber 13 separated by a stoker 11 therein, and has a stove pipe 14 connected to the top of the main combustion chamber 10 at the outdoor side and an air adjuster 15 coupled to a lower end of a rear outer side.
The first combustion chamber 12 is a space where firewood that is the fuel of the fireplace boiler is burned, ashes remaining after the firewood are burned in the first combustion chamber 12 drop down into the second combustion chamber 13 from the first combustion chamber 11. However, the ashes are held on the stoker 11 while firewood is burned, and the drop into the second combustion chamber 13 through the stoker 11 after the firewood is burned.
The stoker 11, which separates the first combustion chamber 12 and the second combustion chamber 13, is a cylindrical gauze-like member.
The air adjuster 15 that allows air at the outdoor side 1 to flow into the main combustion chamber 10 communicates with the main combustion chamber 10.
The interior fuel intake 20 extends from and communicates with the main combustion chamber 10, is positioned at an indoor side 2, and has a door 21 at the front.
Accordingly, a user opens the door 21 to open the interior port 20, puts firewood into the first combustion chamber 12, ignites the firewood, and then close the door 21, and a window may be disposed on the front side of the door 12 for the user to see the inside of the interior port 20 and the first combustion chamber 12 at the outside in this process.
The hot water circulation pipe 30 has combustion pipes 32 spaced from each other with regular intervals over the first combustion chamber 12 with flame passages 31 therebetween, a hot water outlet 33 disposed around the combustion pipes 32 and positioned at the upper portion of the main combustion chamber 10, and a hot water inlet 34 disposed at the rear portion of the main combustion chamber 10.
Accordingly, the heat from the firewood burning in the first combustion chamber 12 transfers to the hot water circulation pipe 30 disposed around the combustion pipes 32 through the combustion pipes 32 the flame passages 31, so hot water for the boiler can be supplied.
The hot water outlet 33 and the hot water inlet 34 are connected to pipes of the boiler in the same way that a hot water outlet pipe and a hot water inlet pipe are connected to a common boiler, so the detailed description is not provided.
Hot water circulating through the hot water circulation pipe 30 can be heated by the heat of the flame produced in the first combustion chamber 12, so it is possible to heat the floor of an interior space and supply hot water even without an oil boiler or a gas boiler.
Further, in summer, it is possible to prevent heat from flowing to the interior through the indoor port 20 connected to the first combustion chamber 12 and to heat only the hot water circulation pipe 30 by putting and burning firewood in the second combustion chamber 13, whereby it is possible to use hot water without heating the interior in summer.
The hot air circulation pipe 40 has hot air outlets 41 disposed through the upper portion of the front side of the indoor port 20 and hot air inlets 41 disposed through the lower portion of the front side of the indoor port 20, connects the hot air outlets 41 and the hot air inlets 42, and is positioned through the first combustion chamber 12 and the second combustion chamber 13.
The hot air circulation pipe 40 is provided to circulate the air at the indoor side 2 where the indoor port 20 is positioned so that the air is heated. The air at the indoor side flows into the hot air inlet 42 disposed through the lower portion of the front side of the indoor port 20, circulates through the hot air circulation pipe 40 positioned in the first combustion chamber 12 and the second combustion chamber 13, and then flows outside to the indoor side 2 through the hot air outlet 41 disposed through the upper portion of the front side of the indoor port 20.
The air circulating through the hot air circulation pipe 40 is heated by the heat produced in the first combustion chamber 12, so hot air is discharged to the indoor side through the hot air outlet 41, thereby heating the interior air.
Further, an intake fan 46 forcibly sucking the interior air may be disposed in the hot air inlets 42.
Accordingly, when the intake fans 46 are operated to forcibly suck the interior air into the hot water inlets 42, air can easily circulate through the hot air circulation pipe 40, so it is possible to achieve the effect of a hot blower heater for heating interior air.
A cleaning socket 51 is disposed at the upper portion of the rear side of the main combustion chamber 10 and the outdoor port 50 is disposed at a lower portion of the rear side of the main combustion chamber 10 so that ashes in the second combustion chamber 13 can be removed to clean the second combustion chamber 13 or firewood can be put into the second combustion chamber 13. The outdoor port 50 is opened and closed by an outdoor port door.
Further, the cleaning socket 51 is used to check or clean the flame passages 31 or the combustion pipes 32 disposed over the first combustion chamber 12 of the main combustion chamber 10.
A damper 62 is disposed on a rotary shaft 61 in the stove pipe 14 of the main combustion chamber 10, supporting rods 63 are fixed to a side of the main combustion chamber 10, and connection bars 64 are supported by the supporting rods 63, with a first end connected to a side of the damper 62. The damper adjuster 60 is connected to the connection bars 64 in order to move up and down the damper 62 when the connection bars 64 are pulled.
That is, when the damper adjuster 60 is pulled, the connection bars 64 are pulled, so the damper 62 of which a side is connected to the connection bars 64 is lifted by the rotary shaft 61, so the stove pipe 14 is opened.
Further, when the pulled damper adjuster 60 is pushed, the pulled connection bars 64 are pushed back, so the lifted damper 62 is moved down, whereby the stove pipe 14 is closed.
An air intake port 71 for sucking exterior air is disposed outside the main combustion chamber 10, an air intake line 72 extends from the air intake port 71, and an air exit port 73 is disposed in the indoor port 20 to supply the exterior air flowing inside through the air intake line 72 to the first combustion chamber 12. The ash shield 70 covers the air exit port 73 to block ashes.
The ash shield 70 prevents the air exit port 73 from being clogged with ashes by covering the air exit port 73 connected to the first combustion chamber 12.
The air exit port 73 is provided to discharge exterior air to the first combustion chamber 12. Exterior air flows inside through the air intake port 71 exposed outside the main combustion chamber 10, keeps flowing into the main combustion chamber 10 through the air intake line 72, and is then discharged to the first combustion chamber 12 of the main combustion chamber 10 through the air exit port 73, whereby air for burning the firewood in the first combustion chamber 12 is supplied.
