Technical Field
[0001] 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
[0002] 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.
[0003] Fireplaces have various and unique designs, so they are used as an interior decorative
structure in a room in other seasons except winter.
[0004] 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.
[0005] 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.
[0006] 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.
[0007] 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.
[0008] 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.
[0009] However, the configuration is used as a fireplace and a boiler system, but is not
given any additional configuration, so spatial usability is low.
[0010] 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.

Mode for Invention
[0020] Hereinafter, other objects and characteristics of the present invention except the
objects described above will be made clear through the following description about
embodiments referring to the accompanying drawings.
[0021] Unless otherwise defined, all terms including technical and scientific terms used
herein have the same meaning as commonly understood by one of ordinary skill in the
art to which the present invention belongs. It must be understood that the terms defined
by the dictionary are identical with the meanings within the context of the related
art, and they should not be ideally or excessively formally defined unless the context
clearly dictates otherwise.
[0022] Hereinafter, regenerative fireplace boilers according to embodiments of the present
invention will be described in detail with reference to the accompanying drawings.
[0023] 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.
[0024] 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.
[0025] 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.
[0026] The stoker 11, which separates the first combustion chamber 12 and the second combustion
chamber 13, is a cylindrical gauze-like member.
[0027] 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.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] 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.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] 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.
[0037] 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.
[0038] Further, an intake fan 46 forcibly sucking the interior air may be disposed in the
hot air inlets 42.
[0039] 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.
[0040] 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.
[0041] 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.
[0042] 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.
[0043] 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.
[0044] 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.
[0045] 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.
[0046] 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.
[0047] 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.
[0048] A cover 44 having a knob 43 and opening/closing the hot air outlet 41 is disposed
in the hot air outlet 41, and the gauze-like grill 45 connected to the cover 44 is
further disposed at the lower portion in the hot air outlet 41.
[0049] Accordingly, it is possible to roast sweet potatoes, nuts, and potatoes etc. by the
gauze-like grill 45 and the knob 43 of the cover 44 makes it possible to easily take
the gauze-like roaster 45 out of the hot air outlet 41.
[0050] Further, shelves 22 facing each other are disposed on the inner side of the indoor
port 20 having the door 21.
[0051] Accordingly, when a user opens the door 21, puts food in oven bowls, for example,
to cook fishes or chickens, and then puts the oven bowls on the shelves 22 in order
to cook food. Heat is applied to the food through the first combustion chamber 12,
so the user can cook food like using an oven.
[0052] Further, a humidifier 23 is coupled to the front side of the indoor port 20 and has
a vapor exit 23a exposed through the front side of the indoor port 20 and a water
container 23b connected to the vapor exit 23a and disposed inside the indoor port
20.
[0053] The humidifier 23 is disposed at the center of the indoor port 20 where the hot air
outlet 41 is disposed, so when a user fills the water container 23b with water and
then puts the water container 23b into the indoor port 20, the water in the water
container 23b is heated and vapor that is generated in this process of heating is
discharged to the indoor through the vapor exit 23a disposed through the front side
of the indoor port 20, so the indoor is humidified.
[0054] A freeze protection electric heater 80 is further disposed in the main combustion
chamber 10 and is electrically connected to a temperature sensor 81 for detecting
the temperature at the outdoor side where the main combustion chamber 10 is disposed
and a freezing-bursting sensor 82 for operating or stopping the freeze protection
electric heater 80 in cooperation with the temperature sensor 81.
[0055] Accordingly, when the fireplace boiler is not used in winter, the temperature sensor
81 detects the outdoor temperature and operates the freeze protection electric heater
80, so it is possible to prevent the hot water circulation pipe 30 from freezing and
bursting.
[0056] Further, the outdoor port 50 protrudes from the rear side of the main combustion
chamber 10 and a pot 90 is disposed over the outdoor port 50.
[0057] Since the pot 90 is provided, it is possible to use the pot 90, for example, in order
to cook rice or other food, in which the source for heating the pot 90 is the heat
produced in the process of combustion in the first combustion chamber 12 and the heat
from the charcoals that drop into the second combustion chamber 13 while the firewood
is burned in the first combustion chamber 12.
