Description

Gudle system with improved heat storage {Korean-type hypocaust system}

The present invention relates to a sphere system, and more particularly, to a sphere system having improved heat storage properties.

As is widely known, ondol heating is a traditional heating method in our country that has been handed down from our ancestors. You can effectively heat a room by appropriately using radiation that spreads in the room and convection that warms the room by circulating the air in the room up and down.

Conventional bulbs generally supply heat from the furnace to the whale while heating the gutuljang laid on the whale. Some of the heat moves along the whale and is discharged with smoke to the outside through the chimney.

As described above, these conventional spheres have a problem in that the movement path of the heat guided into the whale is short, so that the heat is not sufficiently transferred to the sphere and escapes at a high speed, resulting in significant heat loss.

In order to increase the thermal efficiency of spheres as in Patent Document 1, (bang) whales are formed in a zigzag or 'ㄹ' shape to provide a meandering passage. This forms a vortex at the part where the flow direction of heat and/or smoke is changed, resulting in fluid stagnation and poor heat transfer.

Gudeul exhausts the heat and smoke generated from the furnace to the chimney through a plurality of whales formed between a plurality of whalebanks. there is. These spheres have a considerable heat loss problem due to the structure that can easily discharge heat from the furnace through the whale to the chimney.

Therefore, there is a need for improved spheres that can keep warm for a long time while evenly transferring heat to the sphere.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The sphere system (hereinafter referred to as the sphere system) with improved heat storage according to a preferred embodiment of the present invention is configured to not only extend the residence time of hot air by means of a heat storage induction block, but also to evenly heat and spread the heat. .

1 to 3, the sphere system according to the present invention passes the heat and smoke generated in the furnace 110 through a plurality of whales 140 formed between a plurality of whale banks 130 and passes through the chimney 160 to the outside. It is discharged to, and includes a gudeuljang 170 that is disposed on the upper side of the whale 140 and transmits heat passing through the whale to the floor of the room.

On the other hand, the one-dot chain arrow marked on the drawing means the movement path of hot air (and smoke).

As is well known to those skilled in the art, the furnace 110 generates heat (or fire heat) through combustion of various fuels such as firewood, coal, and charcoal, and supplies it to the whale 140. The furnace disclosed in the present invention may be a chamber type furnace that provides a combustion space inside the wall (W), and a cooking space such as a cauldron can be secured at the top of the furnace.

Moreover, the gudeul system according to the present invention arranges the firewood 120 formed obliquely upward toward the whale 140 in the furnace 110 to heat generated in the furnace 110, several whales 140 to be described later It can be supplied by being absorbed well and evenly distributed. As shown, since the fire wood 120 is disposed adjacent to the furnace 110, the floor (lower wood) located above the fire wood can be very hot, and the floor (upper wood) located on the side of the chimney farther from the fire wood is relatively It can be warmed to lukewarm.

A plurality of whales 140 are moving passages that help to escape the heat guided from the firewood 120 to the flue 150, and the floor of the room can be heated by heating the Gudeuljang 170 by the heat passing through the whale. The whale is partitioned so that heat can be moved in a certain direction to a plurality of whale banks 130 supported by the whale bottom (B) and standing upright. The whale bank 130 may be formed by stacking, for example, bricks, soil, etc. at a certain height on the whale bottom (B). Here, the whale bottom is the bottom surface of the whale and is filled with soil or ocher between the walls to form the basic height of the room.

The plurality of whale banks 130 extend in length across the furnace 110 and the flue 150 along the moving direction of the heat, are spaced apart from each other at predetermined intervals, and may not contact the inner surface of the wall W. there is. As shown, the present invention forms a whale 140 between one whale bank 130 and another whale bank 130 adjacent thereto, and puts a gudeuljang 170 on the whale bank. In other words, the whale 140 has a hollow shape limited to the whale bottom B, the gudeuljang 170, and the whale bank 130 along the moving direction of the heat.

In addition, the chimney 160 communicates with the whale 140 by way of the flue 150, and is a component that discharges smoke formed by carbonization together with heat.

Gudeuljang 170 may be a thin and wide stone plate, and as described above, it is seated and installed on the whale bank 130. While the heat generated in the furnace 110 passes through the whale 140, the heat is conducted to the gudeuljang 170 and accumulated for a long time. The heat accumulated in the Gudeuljang can be transferred to the floor of the room to realize indoor heating. In the present invention, a room floor (not shown) may be formed on the Gudeuljang 170 to a predetermined thickness.

Moreover, the present invention forms a thin thickness of the gudeuljang from the firewood to the flue along the moving direction of the hot air so that the gudeuljang near the flue and the gudeuljang near the furnace can be heated uniformly as a whole.

Specifically, the sphere system according to the present invention includes a heat storage induction block 180 protruding from the side of the whale bank 130.

The heat storage induction block 180 protrudes from the side of the whale bank 130 along the moving direction of the heat, preferably alternately without contacting each other on the two sides of the whale bank facing each other to partition the whale. protrusions can be formed. Preferably, the heat storage induction block 180 is disposed on the downstream side of the whale bank 130 to delay the flow of heat in the vicinity of the upper neck.

In particular, the heat flowing through the whale 140 formed in the direction in which the furnace 110 and the flue 150 face each other is higher than that of the whale 140 located on both sides of the direction in which the furnace 110 and the flue 150 face each other. The movement path is short and the flow rate is fast, so the heat cannot be sufficiently transferred to the furnace and escapes to the flue 150 at high speed, resulting in significant heat loss. A heat storage induction block 180 may be formed on the whale bank 130 of the formed whale 140.

By arranging the heat storage induction block 180 in a zigzag pattern along the longitudinal direction in the inner hollow of the whale 140, the hot air strikes the front surface 181 of the heat storage induction block 180 and causes a vortex or turbulent flow, thereby causing the whale It is possible to extend the residence time in the inside, so that the heat transfer efficiency can be increased.

More preferably, the heat storage induction block 180 is formed in the shape of a column having a right triangle or an obtuse triangle as a base, and a front face 181 facing the upstream side of the whale 140 and the downstream side of the whale 140. It includes a rear surface 182 facing the , and a facing surface 183 disposed to face the side of the whalebank 130 . Here, the facing surface 183 is disposed in face-to-face contact with the side surface of the whale bank 130 as one side corresponding to the hypotenuse of the bottom surface, but preferably, the opposite surface and the side surface of the whale bank may be integrally coupled to each other.

In addition, the heat storage induction block 180 is provided with a height size corresponding to the height of the whale bank 130 so that the bottom surface of the Gudeuljang 170 can be supported in contact with the whale bottom (B).

Thus, the present invention is configured to provide a meandering passage of heat in the inner hollow of the whale 140 by the heat storage induction block 180, as described above, by improving the residence time of the heat as well as the opportunity to contact the heat It can reduce heat loss, increase thermal efficiency, and increase heat storage effect to keep the Gudeuljang warm for a long time.

As in Patent Document 1, the conventional spheres are made of a 'D'-shaped bending structure of the guide dam and the diffusion dam to form a zigzag whale in order to extend the residence time of the heat, which is between the guide dam and the guide dam. The focus is on increasing the heat conduction efficiency on the floor by rapidly transporting heat. However, while the hot air moves the zigzag whale, confinement vortices are formed at the corners of the whalebank, and ashes (foreign matter) are stacked and solidified.

Therefore, as shown in the present invention, since the angle θ between the whale bank 130 and the rear surface 182 of the heat storage induction block 180 is set to an obtuse angle, the opening between the rear surface 182 and the whale bank 130 It is possible to minimize the occurrence of confinement vortex by gently inducing the flow of heat by preventing rapid change of the flow path in advance, and to improve the heat transfer effect in the gutuljang and whalebank by minimizing the accumulation of foreign substances at the corner where the rear and whalebank intersect. can Of course, the heat storage induction block can induce the flow smoothly without isolating or stagnating the heat even at the intersection of the front and whalebanks. This structural feature helps ensure the escape of smoke through the chimney.

In addition, as shown, the heat storage induction block 180 has an upwardly curved surface 181a concavely formed on the front surface 181 that encounters heat. In other words, the upwardly curved surface 181a is inclined to be upwardly curved from the lower part of the front surface of the heat storage induction block to the upper part.

As described above, the upwardly curved surface 181a provides a structure capable of inducing a natural flow of heat toward the ball field 170 by giving a slope to the front surface 181 of the heat storage induction block 180. This can change the direction of the hot air that hits the front of the heat storage induction block 180 to another whale bank disposed opposite to the center of the whale while moving upward. As a result, the present invention can maximize heat transfer by delaying some of the flow of heat from the bottom of the field by the upwardly curved surface 181a of the heat storage induction block 180, while the two sides of the whale bank facing each other without stagnation of heat It is possible to transfer or store heat in a wide area as much as possible by smoothly detouring in a zigzag manner.

In the present invention, the heat generated in the furnace is heat-storage and diffused to the whale bank 130, the ball field 170, and the heat storage induction block 180 surrounding the whale 140, so that heat can be transferred uniformly to the entire floor of the room. In addition, the present invention may include a heat storage material 184 capable of accumulating heat in the heat storage induction block 180 to keep the spheres warm for a long time by increasing heat storage efficiency. The heat storage induction block 180 forms an accommodation space (no reference numeral) for sealingly accommodating the heat storage material 184 therein. The heat storage material 184 may be filled in the receiving space of the heat storage induction block in a granular state with at least one selected from silica sand, elvan stone, and alum stone alone or mixed. The thermal storage material can accumulate heat from the heat passing through the whale and store it for a long time.

4 is a perspective view schematically showing another example of a heat storage induction block applied to the sphere system according to the present invention. The heat storage induction block shown in FIG. 4 is a modified example of the heat storage induction block shown in FIG. 3 and has a very similar structure except for the front structure of the heat storage induction block. Or a description of the same configuration will be excluded here.

As described above, the heat storage induction block 180 is formed in the shape of a triangular prism having a right triangle (or obtuse triangle) as its base, and as shown in FIG. 1, the front face 181 facing the upstream side of the whale, It includes a rear surface 182 facing the downstream side of the whale, and an opposing surface 183 disposed facing the side of the whalebank 130.

Furthermore, the heat storage induction block 180 may protrude a plurality of protruding pins 185 on the front surface 181, preferably on the concave upwardly curved surface 181a. The protruding fins can generate vortices or turbulences in the hot air that hits the front surface of the heat storage induction block, preferably an upwardly curved surface, thereby delaying the flow of hot air on the front surface of the heat storage induction block.

Optionally, the protruding pin 185 extends to the accommodation space of the heat storage induction block 180 and quickly transfers heat to the heat storage material filled in the accommodation space to increase heat storage efficiency. Accordingly, it is preferable that the protruding pin is made of a thermally conductive material.

Although the present invention has been described in detail through examples, this is for explaining the present invention in detail, and the sphere system with improved heat storage according to the present invention is not limited thereto, and within the technical spirit of the present invention, It will be clear that the modification or improvement is possible by those skilled in the art.
