Description

Pellet stove}

The present invention relates to a pellet stove, and more particularly, to a pellet stove capable of increasing the thermal conductivity and thermal efficiency of the pellet.

Generally, various heating stoves using oil, gas or electricity are provided in winter.

Such a heating stove can maintain a constant temperature and is easy to use, and is mostly used. However, there is a problem that the heating cost is frequently generated along with the high price, and air pollution due to the combustion gas occurs.

Accordingly, there have been variously presented pellet fireplaces in which wood-pellets are used as alternative energy by pulverizing forestry waste, harvested wood and the like into sawdust and compacting them into a cylindrical shape.

Pellets are widely known as eco-friendly energy sources that can supply fuel in a uniform form and can control the amount of energy accurately and help reduce energy costs. Research using such pellets has been actively conducted in various fields.

The pellet furnace using such a pellet is composed of a charging port into which the pellets are charged, a cylindrical body having a combustion chamber formed therein, and an exhaust pipe connected to the main body. The pellets are introduced into the main body through the charging port, And is transmitted through the outside of the main body to be heated.

However, the conventional pellet stove has a structure in which a plurality of combustion holes are perforated in a conical structure of a combustion chamber structure, in which a combustion hole is easily clogged by the pellet fuel injected or a large amount of residue generated after the pellet fuel is burnt, There is a problem that the efficiency of heating is lowered by a clogged heating device.

Further, there is a problem that after the ash generated from the combustion of the pellets moves on the rising air stream, the pellets are attached to other structures and overheated. That is, since an association for providing a discharge path for the combustion gas is arranged on the upper side of the combustion chamber, there is a problem that after the ash generated in the combustion chamber travels on the ascending air stream, it is attached to the association and is overheated.

In addition, since the pellet fuel injected by the inlet of the conventional pellet furnace is vertically lowered and falls directly to the combustion chamber side, there is a problem that the heat loss is increased because the heat efficiency is transmitted proportionally to the burning time of the pellet fuel.

As a prior art, a pellet stove, which is a registered patent 10-1409989, has been proposed. The pellet stove is formed in a hollow shape extending vertically and has a storage part for storing pellets therein and a pellet provided below the storage part, A heat rising pipe which is formed in a hollow shape extending in the vertical direction and which is arranged in parallel with the structure and in which the heat source generated by the combustion of the pellets is lifted, and a heat rising pipe which is connected to one side of the combustion chamber And a combustion furnace formed to extend from one side of the combustion chamber to one side of the heat rising pipe facing the same direction as the one side of the combustion chamber.

Such prior art prevents the ash generated in the combustion chamber from being moved in the direction of the combustion furnace by the combustion furnace formed with the inclined blocking portion, thereby preventing the ash from being attached to the combustion furnace or the heat rising pipe to overheat.

However, in the case of the prior art, since the components are complicated, the production cost is increased, which causes a problem of cost for purchasing by the consumers.

Korean Registered Patent No. 10-1409989 (Registered on June 13, 2014) Korean Patent Publication No. 10-2014-0118362 (Published Oct. 20, 2014)

This design prevents the pellet from dropping rapidly due to slope descent, rather than direct vertical drop, in the course of pellet injection into the combustion chamber, to allow the ash to fall easily into the ash base of the combustion chamber, and to reduce the waste of unburned pellets And the thermal conductivity and heat efficiency of the pellet can be greatly improved, and the pellet furnace can be miniaturized by a simple structure to minimize the purchase cost of the pellet.

In order to achieve the above object, the present invention provides a pellet stove comprising: a stove body having a combustion chamber therein; a safety net for installing an outer surface of the stove body; a pouring port into which the pellets are inserted; And a combustion port located in a combustion chamber provided in the inside of the hearth body and extending from a lower portion of the inlet port, wherein the combustion port includes: a plurality of outer cylinder pieces extending vertically downward from a lower portion of the inlet port; An air inflow space located between the plurality of outer cylinder pieces; A slanting guide net disposed at an inner center of the plurality of outer tube pieces and inclined downwardly and fixed by welding with the plurality of outer tube pieces; And a plurality of outer cylinder slabs disposed on the lower side of the slant guide net and connected to the plurality of outer cylinder slabs by a welding operation, And an auxiliary net disposed on the lower side of the ash container and allowing the unburned pellet fuel falling from the combustion net to be placed thereon to complete the combustion, Further comprising a combustion housing in which a lower portion of the communication hole is received so that a heat source generated in the combustion chamber is transmitted from the combustion chamber to the communication hole, and a heat source delivery port for connecting the combustion chamber and the combustion housing, A heat source transmission line is further provided, and the heat source transmission line includes: a first heat source transmission line connected to the combustion chamber; A second heat source path provided at one side of the first heat source path and through which heat is transferred from the first heat source path; A third heat source path provided at one side of the second heat source path and connected to the inside of the combustion housing; A first partition wall provided between the first heat source passage and the second heat source passage; And a second partition wall provided between the second heat source passage and the third heat source passage, wherein the communication pipe further comprises an adjusting member for adjusting the escape of the heat source from the communication member, A rotating shaft which is formed in the communication pipe; A control plate connected to the rotation shaft and rotated inside the communication port by rotation of the rotation axis to open and shut off the inside of the communication port; A handle extending from one side of the rotary shaft and located outside the communication; And a hook portion provided on an outer surface of the communication hole and having a plurality of hook groove portions to which the handle is hooked.

Further, the inlet may further include a guide groove, and further includes a fuel adjuster which is inserted in the guide groove to open or close the inside of the inlet so as to adjust the amount of pellets injected through the inlet, A guide plate which is inserted into the guide groove provided in the input port and is drawn in and out of the input port or in the input port along the guide groove; And a grasping portion extending vertically from the guide plate and positioned outside the loading port.

In the present invention, since the heat source generated by the combustion of the pellets passes through the bent heat source transfer path in the process of being transferred by the heat source transfer path, the thermal conductivity can be greatly improved due to the longer residence time to the heat source. , It is possible to completely burn the pellets, and the combustion efficiency of the pellets can be reduced to a high level because the secondary combustion is carried out again by the inclined guide net, It is possible to reduce the production cost by simple configuration, and it is possible to minimize the cost incurred by the installation.

The combustion hole 30 of the present invention includes a plurality of outer cylinder pieces 31 extending vertically downward from a lower portion of the inlet 20 and an air inlet space 32 located between the plurality of outer cylinder pieces 31 A plurality of the outer cylinder pieces 31 are fixed by welding with the plurality of outer cylinder pieces 31, and the plurality of outer cylinder pieces 31 are positioned at an inner center of the plurality of outer cylinder pieces 31 and inclined downwardly, A slant guide net 34 having a first hole 33 and a plurality of outer cylinder pieces 31 located below the plurality of outer cylinder pieces 31 so as to be positioned on the lower side of the slant guide net 34, (36) having a second hole (35) which is connected and fixed by a welding operation and is smaller in size than the first hole (33).

As shown in the figure, the plurality of outer cylinder pieces 31 are formed while being spaced apart from each other at regular intervals in the vertical direction, so that the air inlet space 32 is naturally positioned between the plurality of outer cylinder pieces 31 .

At this time, the combustion port 30 may be fixed to the lower side of the charging port 20 by a welding operation.

The inclined guide net 34 and the combustion net 36 are formed in a net shape as shown in the drawing. The first hole 33 formed in the inclined guide net 34 is inserted through the inlet 20, And the size of the second hole 35 formed in the combustion cell 36 is smaller than the size of the first hole 33.

Accordingly, the pellets (not shown) introduced through the inlet 20 are primarily placed on the inclined guide net 34 and burned.

Since the size of the pellet is reduced during the burning process, the pellet, which is placed on the inclined guide net 34 and primarily burned, falls through the first hole 33 of the inclined guide net 34, (36).

When the size of the pellet is reduced during the secondary combustion, the pellet placed in the combustion chamber 36 is secondarily combusted. When the size of the pellet is reduced during the secondary combustion, And falls through the second hole 35 of the second housing 36.

The ash pellet falling from the combustion cell (36) is seated on the upper end of the ash receiving unit (40) and completely combusted (42) having a third hole (41) smaller in size than the second hole (35).

The pellet dropped through the second hole 35 of the subnetwork 36 is seated on the subnetwork 42 and is burnt in the combustion network 36. The auxiliary net 42 is placed in the subnetwork 36, As the secondary combustion progresses, the reduced size pellets fall down through the second holes 35 of the furnace 36 and the dropped pellets fall down into the auxiliary netting 36 located on the lower side of the furnace 36, (42) so that the combustion proceeds in a tertiary manner.

The pellet is completely burned when the tertiary combustion is carried out by being seated in the auxiliary net 42. The material of the pellet which has been completely burned at this time is discharged through the third hole 41 of the sub- And falls down to the receiver 40 to be collected.

As described above, since the pellets introduced from the inlet 20 proceed from the primary combustion in the inclined guide net 34, the secondary combustion in the combustion net 36 and the tertiary combustion in the secondary net 42, As the pellets are completely burned without abandonment in the unburned state, the efficiency of combustion of the pellets is greatly improved.

The present invention is characterized in that a lower portion of the communication hole 50 is connected to the communication hole 50 so that a heat source generated when the pellet is burned by connecting the combustion chamber 11 and the communication hole 50 is transmitted from the combustion chamber 11 to the communication hole 50 And a combustion chamber (60).

Further, a heat source delivery port 61 for connecting the combustion chamber 11 and the combustion housing 60 is further provided, and a heat source transmission path 62 is further provided in the heat source delivery port 61.

The heat source is transferred to the first heat source pathway 63 connected to the combustion chamber 11 and then the second heat source pathway 64 is connected to the lower portion of the communication path 50 through the third heat source pathway 65. [ The heat transferred to the first heat source transmission path 63 is temporarily transferred to the first heat source transmission path 63 side by the first partition 66, And is transmitted to the second heat source transmission path 64 side.

The heat transferred to the second heat source transfer path 64 is temporarily stored in the second heat source path 64 temporarily by the second partition 67 and then transferred to the third heat source path 65 .

The first heat source passage 63, the second heat source passage 64, and the third heat source passage (not shown), which are not linearly transferred to the communication 50 side, 65, the heat source can be left in the heat source delivery port 61 for a long time, and the heating efficiency according to the heat source is greatly improved.

Further, since the heat source transferred through the third heat source transmission path 65 is not directly transferred to the communication 50 side but remains in the interior of the combustion housing 60, Since the heating is progressed evenly by the heat source delivery port 61 provided with the body 10 and the heat source transmission path 62 and the combustion housing 60 located in the lower portion of the communication 50, Efficiency is greatly improved.
