Description

{Korean underfloor heating system}

The present invention relates to semi-twist sleeves in which heat is maintained for a long time even after the fire is turned off and the temperature of the entire room is uniform.

It is the representative heating system in Korea where the heat is supplied to the bottom of the room through the furnace and the heat is warmed through the heat conduction of the floor which is stacked under the floor of the room.

These spheres emit far infrared ray which is advantageous to the human body, and have advantages in comparison with water waves generated in a general hot water boiler and electromagnetic waves generated from an electric plate, and recently interest is increasing with the spotlight of Hanok.

Usually, spheres are supplied to whales, which are empty spaces under the floor of the room, and the floor of the room is heated by the heat conduction of the upper floor of the whale, that is, the floor of the room. In addition, some of the heat supplied to the whale escapes through the chimney opposite the fireplace through the whale to the outside.

However, the sills have the advantages described above, but the heat supplied by the burns can not stay for a long time, escapes through the chimney, has a low heat efficiency, and has a problem of suddenly lowering the floor temperature after the fire is turned off.

In addition, there is a problem that the heat generated from the oven is not evenly distributed throughout the room, and the temperature difference between the lower and upper legs close to the oven is severe.

Due to these problems, it is required to realize a structure in which the bottom floor can be heated for a relatively long time due to the heat entering the whale through the oven, and the structure of the entire bottom floor is uniform.

In addition, terms defined in consideration of the configuration and operation of the present invention may be changed according to the intention or custom of the user, the operator. Definitions of these terms should be based on the content of this specification. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Of course.

The term " half-turn " used throughout this specification is used to mean that half of the heat generated from the furnace is divided into two halves to the left and right sides of the smoke, and is rotated half a turn prior to the entry of the outer halves 20.

Referring to these drawings, the semicircular parts according to an embodiment of the present invention include a cavity chamber 10 for generating heat by burning fuel, outer soles (not shown) connected to the cavity chamber 10 An inner mouth 30 connected to the inside of the outer sheds 20 so as to communicate with the outer sheds 20 and a central canopus 40 in which the heat passed through the inner sheds 30 stay, And an outgoing chimney 50.

The Hamsilvia (10) is an enclosed form of an eggplant (11) and a whale pile. Space is secured to the left and right so that a larger amount of firewood can be placed than conventional eggshells. Once the firewood is on fire, you can add firewood and control the fire (not shown) so that it burns slowly for a long time.

The heat generated in the cabinet 10 moves to the upper leg through the outer legs 20 and flows into the inner legs 30 through the first heat transfer opening h1, 2 through the heat transfer holes h2. In the semi-turning parts of the present embodiment, the heat transferred from the bottom to the top does not directly escape into the chimney, but the length of the holes in which the heat is moved is long so that the heat can stay in the holes for a long time and heat can be transferred.

Referring to FIG. 2, the semicircular parts of the present invention are formed with outer grooves 22, inner grooves 32, central grooves (not shown) at upper portions of the outer grooves 20, inner grooves 30, 42 are stacked, and an outer bottom 23, an inner bottom 33, and a center bottom 43 are stacked on top of each other. The clay material (F) is applied to the top of the bottom material (23, 33, 43). Hwangto has many infrared pharmacological effects and beneficial effects on human body such as promoting blood circulation because of high infrared emissivity. In addition, the enzyme contained in the loess is excellent in antimicrobial activity, and it is said that it is beneficial to health by eliminating bacteria and fungus.

The thicknesses of the outer floor 23, the inner floor 33 and the central floor 43 of the present embodiment are different from each other in accordance with the change in the temperature of the heat passing through the whale and the thicknesses of the bottoms 23, Differently. With this structure, the temperature of the entire floor can be made even, and the heat can stay for a long time and the heat can be sufficiently transmitted.

Referring to FIG. 3 together, the outer sheds 20 are composed of an outer whitetail 21 and an outer shed 22 and are connected to the left and right sides of the sidewall 10 to form the heat and smoke generated in the siphon 10 Thereby forming a passage through which the gas flows.

The outer sills 20 are provided such that the height of the outer saddle 22 is gradually increased toward the direction of the heat and smoke, that is, toward the top. That is, the outer whorl bank 21 and the outer areola 22 form an upward slope in the direction of the heating. The inclination of the outer peripheries 20 is 6 to 10%, preferably 8%, and the bottom of the outer peripheries 20 also forms the same inclination in the advancing direction of the heat. The reason for tilting the outer peripheries 20 as described above is that the whale is inclined in accordance with the formation of the upward flow of the hot air as the hot air moves and thereby the hot air generated in the air chamber 10 is quickly moved to the top, This is to reduce the temperature difference. The hot heat, which has moved to the top, opens and stays in the space (24) for a certain period of time.

On the other hand, the outer floors 23 mainly made of gravel and sand are horizontally filled in the upper part of the outer areola 22. As the outer canopy 20 is inclined, the thickness of the outer floor 23 becomes thicker and thinner toward the uppermost point. That is, the floor of the lower chamber is relatively thick and the thickness of the lower floor of the lower chamber is thinner than that of the lower chamber. Since the thick upper layer of the floor receives heat from the hot heat accumulated in the first space 24, it is possible to reduce the temperature difference with the lower part.

Referring to FIG. 4, the heat transmitted through the outer sidewalls 20 is transmitted through the first heat sink space 24 for a certain period of time, then is lowered at a lower temperature to form a boundary between the outer sidewalls 20 and the inner sidewalls 30 Through the first heat transfer holes h1 formed in the inner holes 30. The first heat transfer holes h1 are formed immediately below the first open top spaces 24 of the outer sills 20. [ That is, when the horizon is drawn from the portion where the outer shoulder 22 of the bottom is started, it is directly below the horizon. As described above, the heat of the high temperature during the heating which has passed through the outer sills 20 is collected at the upper part of the outer sills 20, and the heat is transmitted to the outer saddle 22 and the outer bottom 23, And the heat that has dropped away flows into the inner sills 30 through the first heat transfer holes h1.

The inner sidewalls 30 form a passage through which the heat and the smoke introduced from the outer sidewalls 20 are changed in direction and then moved toward the bottom. The inner sills 30 are inclined such that the height of the inner sills 30 increases toward the direction of the heat and smoke as the outer sills 20. [ The inclination of the inclination is 3 to 5%, preferably 4%. The reason for this is because the heat is moved from the top to the bottom in order to sufficiently increase the temperature of the top so as to slow the moving speed of the heat.

The thickness of the inner side floors 33 filled in the upper part of the inner side girder 32 becomes thinner toward the lower side as the inner whale piles 31 and the inner lower side girder 32 are inclined. Although the temperature of the hot air decreases as the temperature goes down to the lower temperature, the temperature of the floor can be kept constant with the upper temperature as the thickness of the inner bottom 33 forming the floor becomes thinner. The heat that has passed through the inner sills 30 remains in the second sump space 34 for a period of time and transfers heat to the inner shed 32 and the inner sidewall 33.

Referring to FIG. 5, the heat and smoke passing through the inner sills 30 flow into the central canopy 40 through the second heat transfer hole h2. The second heat transfer opening h2 is also formed in the boundary between the inner openings 30 and the central openings 40. The heat of the second open space 34 is maintained for a predetermined time, The second openable space 34 is formed.

The center canopy 40 is horizontally formed so that the heat stays long enough to transmit heat and the height of the central floors 43 is adjusted horizontally as the central whale bank 41 and the central canopy field 42 are laid horizontally .

A plurality of pillars (45) are installed in the central canopy (40). The pillars 45 are provided to prevent the heat from proceeding and to allow the heat to stay in the central canopy 40 as long as possible. The heat entering the central canopy 40 transfers sufficient heat to the pillars and central canopy 42, and the smoke exits through the chimney 50.

The chimney (50) is composed of a horizontal cylinder (51) and an orthogonal cylinder (52). The horizontal bar 51 connects the central canvas 40 and the vertical bar 52 such that the smoke of the central canvas 40 escapes through the vertical bar 52. The height of the inlet of the horizontal bar 51 is formed at a position 1/3 from the height of the center girder 42 to the bottom to prevent hot air from escaping from the upper portion.

A protrusion 51a is formed at a portion where the horizontal bar 51 and the vertical bar 52 are connected. The projecting portion 51a is a portion where a part of the horizontal bar 51 extends into the vertical bar 52. The projecting portion 51a is for preventing a cold wind from entering the central canopy 40 through the horizontal bar 51 by forming a catching jaw when the external cold wind flows back through the upper portion of the vertical barrel 52. [

The vertical barrel 52 is vertically connected to the horizontal bar 51 by discharging the smoke of the central canvas 40 to the outside. A backflow prevention portion 52a is provided at a lower portion of the vertical bar 52. The backflow prevention portion 52a is a space through which the cold air flowing backward through the upper portion of the vertical bar 52 can come down. The bottom of the backflow prevention portion 52a should be formed to be equal to or less than the floor height of the chamber-side oven 10 to exhibit a backflow prevention effect. The cold air introduced from the outside does not directly enter the horizontal bar 51 but stays in the backflow preventing portion 52a. After the temperature rises, the cold air again flows out to the outside or into the horizontal bar 51.

FIG. 6 is an internal structural view of half-turn tools installed in a hexagonal sperm as another embodiment of the present invention.

In the farming and fishing villages, spermatozoa where the villagers can socialize are installed. Recently, there are more households that install sperm in the yard for gardening. These spermatozoa have a problem that the sperm bottom is cold and difficult to use when the temperature drops. However, as in this embodiment, by installing semi-spherical spheres in the sperm, it is possible to increase the period of use during the year by using the fire during the period when the temperature is low, and to use the seasonal fertilizer to dry the crops.

The semicircular parts of the present embodiment are composed of a hollow chamber 60, outer sides 70, inner sides 80, a central canopy 90 and a chimney 50 as in the previous embodiment, The inner sphere 80 and the inner sphere 80 are angled in accordance with the shape of the hexagonal sperm, so that the detailed description of each component will be omitted.

As described above, according to one embodiment of the present invention, the semi-twisted sections include the outer sidewalls 20 connected to the upper leg from the lower leg and the inner sidings 30 connected to the lower leg from the upper sidewall, (40), so that the length of the openings is extended. Therefore, heat can pass through the spheres and sufficient heat transfer can be made, so that the thermal efficiency is high and the temperature of the ondol can be maintained for a long time.

The temperature difference between the upper and lower legs can be reduced by adjusting the thickness of the bottom and top, outer legs 20, inner legs 30 and central canopus 40 according to the movement of the heat and the temperature, .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
