Description

Gudle system with improved temperature uniformity {Korean-type hypocaust system}

The present invention relates to a sphere system, and more particularly, to a sphere system with improved temperature uniformity.

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 the heat from the furnace to the whale while heating the gutuljang laid on the whale. Some of this 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 to the inside of the whale is short and the heat is not spread evenly, so the edge and upper neck of the room are not heated, and the lower neck adjacent to the furnace is too hot to burn the floor of the room. .

Accordingly, those skilled in the art are installing a gyeopgudeuljang (or double gudeuljang) on the firewood to disperse the high-temperature heat rising from the furnace, as shown in FIG. 4 of Patent Document 1. Or, the thickness of the gudeuljang is formed so that it gradually becomes thinner as it goes from the furnace to the chimney. These spheres actually only delay the heat transfer rate of the sphere placed at a position corresponding to the lower neck, and rather have limitations in overcoming the temperature difference between the lower neck and the upper neck by increasing the heat storage efficiency.

Republic of Korea Patent No. 10-1751644

Gudeul is to exhaust the heat and smoke generated in the furnace to the chimney through a plurality of whales formed between a plurality of whalebanks. . Typically, the furnace adjacent to the furnace has a problem that it becomes too hot as the furnace directly contacts the flame generated inside.

Therefore, there is a need for improved spheres that can significantly reduce the temperature deviation of each location of the sphere and increase the temperature uniformity of 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 temperature uniformity according to a preferred embodiment of the present invention is configured to not only guide the movement of heat to the lower neck by means of the heat diffusion block, but also to spread the heat evenly while storing heat. there is.

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

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 from flames generated by burning various fuels such as firewood, coal, and charcoal, and supplies the heat 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 provides a firewood 120 connecting the furnace 110 and the whale 140, helping to direct the heat generated in the furnace toward the central portion of the whale through the firewood. Thus, the gudeul system of the present invention arranges the fire wood 120 formed inclined upward toward the whale 140 in the furnace 110 to raise the heat caused by the flame together with the flame generated in the furnace 110 to several It can be supplied by being evenly distributed while being sucked into the forked whale 140. 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 far from the fire wood is relatively warmer than the lower wood. It can be heated to lukewarm.

A plurality of whales 140 are moving passages that help to escape the heat guided from the fire tree 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 supported by the whale bottom (B) and is partitioned so that heat can be moved in a certain direction to a plurality of whale banks 130 standing upright. The whale bank 130 is at a certain height on the whale bottom (B), for example, bricks, soil, etc. 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 hot air, 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 is a component that communicates with the whale 140 by way of the flue 150 and 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. The heat generated in the furnace 110 passes through the whale 140 and conducts the heat to the Gudeuljang 170 and accumulates 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, according to the present invention, the thickness of the gudeuljang near the flue and the gudeuljang near the furnace can be uniformly heated as a whole by forming a thin thickness of the gudeuljang from the firewood to the flue along the moving direction of the hot air.

Preferably, the gudeul system according to the present invention is a flame blocking plate 180 on the bottom of the gudeuljang 170 so that the high temperature flame generated during combustion inside the furnace 110 does not directly hit the gudeuljang 170 seated on the firewood. to place In other words, the flame blocking plate 180 is interposed between the bulmok 120 and the gudeuljang 170 placed at a position corresponding to the lower neck, and spaced between the bulmok 170 and the bulmok 120 of the lower neck disposed on the bulmok Can be spaced apart.

Specifically, the present invention provides a first separation space (S) between the lower neck gudeuljang 170 and the flame blocking plate 180, while providing a second separation space between the bulmok 120 and the flame blocking plate 180 ( no reference sign). Heat and smoke can be guided to the whale through the second separation space.

Since the flame blocking plate 180 is disposed below the bottom of the Gudeuljang, it prevents excessive exposure of the Gudeuljang 170 to the heat of the flame together with the high-temperature flame, thereby lowering the thermal conductivity toward the Gudeuljang adjacent to the furnace, thereby reducing the local area of the lower neck. Heating can be improved. Therefore, it is preferable that the flame blocking plate is made of a non-combustible heat insulating material.

Moreover, high-temperature heat can hit the flame baffle plate 180 and spread radially toward multiple whales. Of course, the heat of the flame may detour to the first separation space (S) between the Gudeuljang 170 and the flame blocking plate 180 to heat the Gudeuljang.

Specifically, the goodle system according to the present invention includes a heat diffusion block 190 capable of guiding the heat passing through the fire neck 120 to the downstream of the whale without a decrease in temperature.

The heat diffusion block 190 is disposed in the inner hollow of the whale 140, preferably disposed upstream of the whale 140 adjacent to the bull neck 120. The heat diffusion block 190 can be placed on the short whales located inside the room (see FIG. 2) as well as on the long whales along the edge of the room.

As shown, the heat diffusion block 190 has a shape and size that can be inserted into the inner hollow surrounded by the whale bottom B, the gudeuljang 170, and the whale bank 130. The present invention solves the chronic problem of the spheres in which only some parts are heated by supporting the lower neck of the sphere with a heat diffusion block that is relatively thicker than the upper neck to prevent the extinction of the sphere in advance and forcibly guiding the flow of heat to the downstream. can

In the present invention, the open air diffusion block 190 has a diffuser hole 191 formed through it from one side to the other side thereof. The diffuser hole 191 is formed in the shape of a tapered truncated cone whose inner diameter gradually increases along the moving direction of hot air, so that hydrodynamic advantages can be expected. In other words, the diffuser hole 191 extends from the inlet opening E1 opposite the flue 120 located upstream of the whale 140 to the discharge opening E2 opposite the flue 150 located downstream of the whale. By increasing the cross-sectional area of the passage, the intake rate of heat and smoke can be improved.

When fluid (heat, smoke, etc.) flows into the diffuser hole 191, the inflow and outflow of the fluid passing through the diffuser hole can be calculated through Equation 1 below.

[Equation 1]

Q = A _E1 V _E1 = A _E2 V _E2

Here, A _E1 is the cross-sectional area of the inlet opening E1 and A _E2 is the cross-sectional area of the outlet opening E2. Further, V _E1 represents the fluid flow rate at the inlet opening and V _E2 represents the fluid flow rate at the outlet opening. Q is the flow rate;

The flow rates at the inlet and outlet openings are equal based on the law of continuity (Equation 1). Therefore, if the flow rate is constant, the cross-sectional area and the flow rate are inversely proportional, so the flow rate of the fluid can be controlled by adjusting the size of the inner diameter of the diffuser hole.

Since A _E1 < A _E2 , V _E1 > V _E2 and the suction speed of the inflow opening E1 is improved. According to the present invention, the heat to be introduced into the whale 140 can be quickly transported downstream by improving the suction speed of the fluid through the diffuser hole.

This not only improves local heating of the lower neck by significantly reducing the contact opportunity between the heat rising from the firewood and the furnace near the furnace, but also quickly moves the high-temperature heat generated from the furnace 110 to the upper neck to reduce the temperature difference between the upper and lower necks. can be reduced

As described above, the pressure of the fluid increases instead of slowing down when the fluid passes through the relatively wide discharge opening E2. Since this is a result of 'Bernoulli's principle' widely known to those skilled in the art, a detailed description thereof will be omitted. The high pressure of the hot air discharged through the discharge opening E2 of the diffuser hole 191 minimizes the burden of reverse flow of the hot air and smoke due to the influence of the head wind introduced through the chimney 160 from the outside, so that smooth exhaust can be expected.

As described above, the heat diffusion block 190 stores heat in the process of providing heat through the diffuser hole 191, so that the floor can be evenly heated for a long time by the heat stored in the ballroom.

Optionally, the present invention is around the inlet opening E1 of the diffuser hole 191 to prevent the phenomenon in advance of the reduction of the area where the fluid flows in the inlet area of the diffuser hole by the vena contracta. It is possible to guarantee the transport ability of the fluid by roundly curving or chamfering.

4 is a perspective view schematically showing another example of an open air diffusion block applied to the sphere system according to the present invention. The hot air diffusion block shown in FIG. 4 is a modified example of the hot air diffusion block shown in FIG. 3, and has a very similar structure except for the arrangement of the diffuser holes. explanation will be excluded.

As described above, the heat diffusion block 190 is formed in the shape of a square pillar or a trapezoidal pillar that can be accommodated in a whale 140 (see FIG. 2), and penetrates the inside from one side to the other side along the direction of movement of the heat. A plurality of diffuser holes 191 are provided. Specifically, the plurality of diffuser holes 191 may be perforated in a truncated cone shape in which inner diameters gradually increase from one side to the other while penetrating from one side to the other side.

A plurality of diffuser holes are formed through the hot air diffusion block in parallel along the moving direction of the hot air.

As described above, the hot air diffusion block 190 includes a plurality of diffuser holes 191, and at least one of the plurality of diffuser holes 191 has a different inner diameter of the discharge opening E2.

The diffuser hole 191 increases the cross-sectional area of the passage along the moving direction of the hot air and reduces the flow rate according to the law of continuity. At this time, the flow rate of the fluid can be adjusted by the size of the cross-sectional area. That is, according to the size of the inner diameter of the discharge opening, the discharge speed of the fluid inevitably varies. Of course, the inlet opening of each diffuser hole may have the same inner diameter. As a result, the hot air discharged through the plurality of diffuser holes 191 causes an uneven flow on the downstream side of the whale 130 due to different discharge speeds, thereby generating vortexes. In this way, the hot air can extend the residence time on the downstream side of the whale, increasing the heat transfer efficiency to the upper neck gudeuljang.

At this time, the hot air diffusion block 190 is not limited to the diffuser holes shown in FIG. 4, and the number of diffuser holes, the arrangement of the diffuser holes, and the inner diameter of each discharge opening are not limited.

5 is a schematic longitudinal cross-sectional view of a sphere system according to another embodiment of the present invention.

Gudle system according to another embodiment of the present invention is a furnace 110, a firewood 120 connecting the whale 140 in the furnace 110, a whale bank dividing the whale 140 on the whale bottom (B), and opening and a chimney 160 for discharging smoke to the outside, a Gudeuljang 170 supported by a whale bank and heated by heat passing through the whale, and a flame disposed under the bottom of the Gudeuljang 170 of the lower neck disposed on the fire tree 120 It includes a blocking plate 180 and an open air diffusion block 190 for guiding hot air to the downstream side of the whale.

Specifically, the present invention is spaced apart at a predetermined interval from the lower surface of the Gudeuljang 170 adjacent to the furnace to provide a first separation space (S) between the Gudeuljang 170 of the lower neck and the flame blocking plate 180. , At this time, it is characterized in that the flame blocking plate 180 is inclinedly disposed under the bottom surface of the Gudeuljang so that the separation distance decreases toward the downstream side.

This shortens the contact time with the flame blocking plate 180 while the high-temperature flame and/or heat rising from the firewood rises rapidly along the slope by reducing the distance between the Gudeuljang 170 toward the downstream side, and also shortens the contact time with the flame blocking plate. The thermal conductivity from the 180 to the gudeuljang 170 is gradually increased from the lower neck to the upper neck so that the gudeuljang from the lower neck to the upper neck can be heated evenly, and only the gudeuljang 170 immediately adjacent to the furnace is heated intensively so that the floor is pressed prevent sticking

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 temperature uniformity according to the present invention is not limited thereto, and within the technical spirit of the present invention, the related field It will be clear that the modification or improvement is possible by those skilled in the art.
