Description

[DESCRIPTION]

[invention Title]

The heating blocks, the heating blocks set, and the manufacturing method of the blocks, and the construction method of the blocks

[Technical Field]

The present invention relates to heating blocks, and more particularly, to heating blocks, each of which is made of loess and has a heat transfer hole for allowing heat to penetrate the inside of the block, thereby transferring heat through a heat passageway formed in such a way that the heat transfer holes of plural blocks are connected with one another when a heating facility is constructed using the heating blocks.

In case where the heating blocks according to the present invention are used, anyone can easily construct a heating system in a Korean hypocaust manner using Korean traditional materials, such as loess, and so on. [Background Art]

The Korean hypocaust is a Korean traditional low- temperature radiant floor heating system to construct the floor of a room through the steps of making a ^λflue of a hypocaust' , which is a passageway to allow passing of heat and smoke, and paving the flue with stones (floor-slab stones used for flooring a room over a Korean hypocaust) . The Korean traditional hypocaust has various merits, such as emission of far infrared rays useful to a human body, useful functions of loess, and a thermal storage function since it uses natural materials, such as loess, floor-slab stones. However, the Korean traditional hypocaust has several problems in that it is complicated in construction work, is short of vocational technicians, and requires a construction period of a long term and many construction fees. Accordingly, the Korean traditional hypocaust makes a gradual retreat due to the above-mentioned problems.

As industrialization has made rapid progress since the twenty century, because the main material of the Korean hypocaust was changed from loess into cement and the used fuels were gradually changed from wood into charcoal, oil, electricity, and so on, the heating method was also changed from a directly heating method using heat into an indirectly heating method using water pipes. However, the indirectly heating method using the water pipes has several problems in that unnecessary energy is consumed since it needs the minimum operation for heating to prevent freeze burst, and in that the pipes must be exchanged when the pipes get aged. Particularly, construction materials frequently used in the modern days emit harmful materials, and hence, in order to keep a healthy life, it is necessary to select various materials and construction methods and develop construction materials to remove such harmful ingredients.

Recently, loess, which is useful to the human body, has been widely utilized as a construction material according to the trend of well-being construction. With such a trend, a demand to embody the Korean traditional hypocaust using loess is gradually increased. However, it is necessary to optimize the Korean traditional hypocaust to the present dwelling culture and construction technology by making up for the problems in complication of construction, the long construction period, and so on so as to popularize the Korean traditional hypocaust in the present construction.

[Disclosure] [Technical Problem]

Accordingly, the present invention has been made in an effort to solve the above-mentioned problems occurring in the prior arts, and it is an object of the present invention to provide heating blocks to easily realize a Korean traditional hypocaust, which has a ^Λflue of a hypocaust' using environmentally-friendly materials useful to a human body, such as loess. In case where the heating blocks according to the present invention are used, since a user can easily make a heat passageway (flue of a hypocaust) as the user wants, anyone can easily realize the Korean traditional hypocaust.

While the present invention is basically invented from the above point of view, the heating blocks according to the present invention can be widely used in the heating field without any restriction in materials or heating methods.

[Technical Solution)

To achieve the above object, the present invention provides heating blocks, each of which is in a cubic form, comprising a heat transfer hole 10 formed in the heating block 100 and adopting one of a " | " shape, a "π " shape, and a "-p" shape, both ends of the heat transfer hole 10 being located at the center of corresponding faces of the heating block. The heat transfer hole 10 may be in a circular form or one of other various forms. In this instance, it is preferable that a length of one side of each heating block ranges from 15cm to 30cm and a diameter of the heat transfer hole 10 formed in the heating block ranges from 7cm to 18cm. The heating blocks of the three shapes may be sold and used in a set.

A user can easily make a heat passageway as he or she wants when he or she assembles the heating blocks 100 of the three shapes respectively having the heat transfer holes 10 adopting one of the "|" shape, the "i " shape, and the "-[-" shape. In the specification and claims of the present invention, the "π " shape means not only a right-angled shape but also a curved shape. The heat transfer hole 10 of the ^λλ-j " shape may be manufactured in such a way as to be bent at right angles or within a range of from 60 degrees to 135 degrees. Accordingly, the heat transfer hole 10 may be,

for example, in the form of a " i ". Of course, the shape of the heat transfer hole may be partially modified if it does not interrupt a flow of heat, and hence, the ^λΛπ " shape includes such a modification. The "-[-" shape also may be partially modified, for example, a bent portion of the "-p" shape may be in a curved form, and hence, the shapes of the heat transfer hole include all of the above-mentioned forms in the specification and claims of the present invention.

The heating block 100 may be made of one of loess, zeolite and elvan or mixture, in which at least two of loess, zeolite and elvan are mixed together. Furthermore, sand, gravel and hardener may be added to the above material. As the hardener, plaster, cement, quicklime, and so on may be used.

It is preferable that the heating block is manufactured by mixing loess of from 15% to 30% by weight, sand of from 20% to 30% by weight, gravel of from 20% to 30% by weight, and plaster of the remainder percent (shortfall of the 100% weight ratio) . In this instance, pulp of from 3% to 20% by weight compared with the mixture, in which the loess, the sand, the gravel and the hardener are mixed together, is added to the mixture.

In another aspect, to achieve the above object, the present invention provides a method for manufacturing the heating block 100 comprising the steps of: (1) mixing the materials at the above-mentioned ratio; (2) adding and stirring water to the mixture; (3) putting the stirred mixture in molds each having the heat transfer hole adopting one of a "|" shape, a "π " shape, and a "-j-" shape; (4) pressurizing and compressing the stirred mixture put in the molds at pressure ranging from lOOkg/cilf to 300kg/cin²; and (5) drying the compressed mixture. In this instance, in the drying step, the mixture is naturally dried at room temperature for one day to ten days or dried by heat ranging from 10^°C to 65 ^°C .

In a further aspect, to achieve the above object, the present invention provides a construction method of the heating blocks comprising the step of: laying the heating blocks on the prepared floor in such a way that the connection recess 11 of the heat transfer hole 10 of one heating block 100 is joined to a connection projection 12 of the heat transfer hole 10 of the neighboring heating block 100 to thereby connect the heat transfer hole 10 of one heating block 100 to the heat transfer hole 10 of the neighboring heating block 100, whereby a heat passageway is formed long. In this case, the entire form of the heat passageway is determined according to a user' s intention or situations. Moreover, it is preferable to fill up and paint an interval formed on a connected portion between the heating blocks 100. The paste 50 may be manufactured in such a way as to mix loess of from 40% by weight to 80% by weight and sand of from 20% by weight to 60% by weight. Water of a proper amount is added according to conditions or environments in order to knead the mixture.

[Advantageous Effects] The heating blocks 100 according to the present invention can easily realize the Korean traditional heating system just when the heating blocks are connected with one another since the wanted materials including loess are molded in the block form in such a way as to have a heat transfer hole inside the block. Furthermore, since the heating blocks are formed in a cube using materials, such as loess, and each has the heat transfer hole adopting one of three shapes, the heating blocks according to the present invention can maximize the use of environmentally-friendly materials and convenience in construction of the Korean hypocaust. According to the present invention, since the hypocaust and a chimney can be completed in a simple method that the cubic blocks are piled up along X, Y and Z axes, the present invention can remarkably reduce a construction period and construction fees and save heating energy. Accordingly, the present invention can popularize the Korean traditional heating system, which has been disregarded due to the complicated construction work and the long construction period even though it has several merits, for example, it is made of loess, which is useful to the human body.

[Mode for Invention]

Reference will be now made in detail to the preferred embodiment of the present invention with reference to the attached drawings . As shown in the drawings, a heating block 100 according to the present invention is in a cubic form. The reason is to make assembly of plural heating blocks easy.

The heating block 100 includes a heat transfer hole 10 formed therein in such a way as to perforate the heating block 100, and the heat transfer hole 10 adopts one of a " I " shape, a "π " shape, and a ^w-j-" shape. If the heating blocks of the three basic shapes are all prepared, a user can make a heat passageway as he or she wants by assembling them. In order to make the assembly of the heating blocks 100 easy, both ends of the heat transfer hole 10 are located at the centers of the corresponding faces.

In order to make the assembly easier and more stable, it is preferable to form a connection recess 11 and a connection projection 12 on outer peripheral surfaces of the both ends of the heat transfer hole 10 in such a way as to be formed correspondingly to each other. Then, the connection projection 12 outwardly projecting from the heat transfer hole 10 is joined to the connection recess 11 formed on one neighboring heating block to thereby reinforce sealability of the heat transfer hole 10 and stability in combination between the two heating blocks.

According to the present invention, a hypocaust made of environmentally-friendly materials, such as loess, can be simply constructed in the same form as a heating hose of an underfloor boiler. As shown in FIGS. 4 and 5, the heat transfer holes 10 of the heating blocks can be connected with each other in such a way as to be located in a room in a generally zigzag form. Accordingly, gas or heat of high temperature heated by a separate heating device can heat a facility evenly while flowing along the heat transfer holes

10.

According to a test by the inventors, it is preferable that a length of one side of each heating block 100 ranges from 15cm to 30cm in consideration of convenience in construction. If the heating blocks exceed the above range, it causes inconvenience in carrying or construction.

Moreover, it is preferable that a diameter of the heat transfer hole 10 of the heating block ranges from 7cm to 18cm. If the diameter of the heat transfer hole 10 is below the range, a friction force acting to a heat medium flowing through the heat transfer hole 10 gets excessive.

The heating block 100 according to the present invention is not restricted to particular materials but can be made of various materials. As an example, loess, which is recently in the limelight as the representative environmentally-friendly construction material, will be described.

When the heating block 100 is manufactured using loess, the heating block 100 may include loess, sand, gravel, and plaster as a hardener, and in this instance, it is preferable that a ratio of the mixture is loess of from 15% to 30% by weight, sand of from 20% to 30% by weight, gravel of from 20% to 30% by weight, and plaster of the remainder of the ratio (shortfall of the 100% weight ratio) . The above ratio of the mixture is a ratio selected to optimize durability and a heat storage function. In this instance, water is added to the mixture and stirred. An input ratio of water may be changed according to working environments of the facility, weather and other various conditions, and easily decided by the user according to situations. In general, water of from 3% to 10% by weight compared with weight of the mixture, in which the loess, sand, gravel and plaster are mixed together. In the meantime, loess, which is useful to the human body, out of the above constituent ingredients is inputted to the heating block to serve as a binder.

Physical properties of the constituent ingredients will be described. The loess consists of catalase, diphenol oxidase, saccharase, and protease as enzyme ingredients. Catalase serves to remove toxins, diphenol oxidase serves to decompose protein, saccharase serves as one of fertilizer ingredients, and protease provides a purification action. It was reported that catalase shows the highest activity in soil ingredients and removes hydrogen peroxide, which provides a toxin to living things, to thereby make a proper soil environment for lives of living things. Furthermore, catalase shows the effect to neutralize and dilute lipid- peroxidation, which is a toxin generated during the metabolism action in a human body to thereby cause aging, by virtue of a strong absorption force of soil to thereby restrain aging.

The effects of loess will be described in more detail as follows. First, loess shows an excellent effect to keep the head cool and the feet warm. That is, natural loess stone keeps the head cool and the feet warm by lowering a high heat.

Second, loess of Ig contains two hundred million microorganisms useful to the human body, and it verifies that the loess stone lives and breathes. Third, loess emits far infrared rays of a high rate to thereby prevent aging, promote the blood circulation, remove stress, aid skin beautification, and is effective to treat neuralgia, lumbago and chronic fatigue. Fourth, loess emits a great deal of anions.

Fifth, loess prevents inhabit various kinds of molds and germs harmful to the human body.

Sixth, loess serves to neutralize lipid-peroxidation, which is a toxin harmful to the human body. Accordingly, when the heating block according to the present invention is manufactured using loess as the main material, the present invention can provide the above- mentioned effects. Nowadays, with the trend of well-being, various materials emitting far infrared rays or anions, such as loess, elvan, and so on are in the limelight as raw materials for building materials, and hence, the present invention will be a technical development corresponding to the flow of the times.

Next, sand is mixed with loess and gravel as aggregate of the block and provides a strong binding force. When an input ratio of sand is adjusted, it can prevent a crack of the block and control work efficiency.

Next, it is preferable that a size of gravel ranges from lcm to 2cm. Gravel serves to reinforce a compression strength of the block hardened as the aggregate. In fact, the loess blocks according to the present invention must have durability as strong as it can endure pressure to some degree since they are laid on the floor and have to support weights of people and furniture. The inventors obtained a data through a test that a floor covering has to accept pressure of about lOOkg/αtf. The gravel in the present invention is a constituent ingredient to keep such durability.

Finally, in the present invention, plaster is added as the hardener for the heating block. Loess obtains a good strength when it is dried, but is restored to a powder state since its strength is deteriorated when it is exposed to water or moisture. In order to prevent the restoration to the powder state and reinforce the compression strength, plaster is added. Since the heating block is used for heating, organic adhesives, such as starch, are not added.

Moreover, it is preferable that pulp of from 3% to 20% by weight compared with the mixture is added to the mixture. The pulp is a fibroid material produced through the steps of cutting coniferous trees and broadleaf trees and digesting and hydrolyzing them. The pulp is an intermediate product produced into paper and fiber through reproduction. Since the pulp has a number of pores and a great deal of twigs, it serves to prevent scatter of the above constituent ingredients after being added to the heating block of the present invention. That is, the pulp performs a role similar to reinforcing rods embedded in concrete. Accordingly, the pulp is added in order to manufacture the heating block, which is more firm and has excellent durability.

A manufacturing method of the heating block according to the present invention, for an example, using loess as the main material, will be described. First, in the first step, input and mix loess, sand, and so on described above. That is, in the first step, input and mix loess of from 15% to 30% by weight, sand of from 20% to 30% by weight, gravel of from 20% to 30% by weight, and plaster of the remainder of the ratio (shortfall of the 100% weight ratio) . First, powder-type loess and sand are mixed evenly, and then, gravel and plaster are added and mixed at the above input ratio. It is important to keep the above ratio, and a mixer and a stirrer for mixing the above-mentioned ingredients may be used differently according to environments.

Next, in the second step, add and stir water of from 3% to 10% by weight compared with the weight of the mixture produced in the first step. That is, add and stir water to the mixture, in which the loess, sand, gravel and plaster are mixed together. The water is water generally used in most of mortar, and it is important to add water of a proper amount according to conditions.

In the third step, put the stirred mixture into molds each having the heat transfer hole adopting one of a "|" shape, a "^~i " shape, and a "-[-" shape. It is natural that the molds are in the cubic form as described above.

In the fourth step, pressurize and compress the stirred mixture put in the molds at pressure ranging from 100kg/cnf to 300kg/cui^!. In this step, since intervals among the constituent ingredients get narrow while moisture to some degree vents out, the heating block of high density and gravity can be manufactured. Such a pressurizing step is needed since the heating block according to the present invention must have durability and firmness as strong as it can support all weights of people, furniture and electronic equipments. Of course, a detailed numerical value of pressure may be varied according to used places and a qualitative difference of inputted constituent ingredients. Finally, in the fifth step, dry the mixture, whereby manufacture of the heating block 100 is finished. In the drying step, naturally dry the mixture at room temperature for one day to ten days or dry it with heating ranging from

10^°C to 65^°C. In case of the natural drying, while there is a problem in that productivity lowers, it has a merit in that it can save energy used for drying with heating to thereby reduce manufacturing costs.

In the first step, pulp may be added to the mixture, and it is described above. In order to construct a facility using the heating blocks manufactured according to the present invention, lay the cubic heating blocks on the prepared floor. In this instance, the heat transfer hole 10 of one block and the heat transfer hole 10 of the neighboring block are connected with each other in such a way that the connection recess 11 of the heat transfer hole 10 of the one block 100 is joined to the connection projection 12 of the heat transfer hole 10 of the neighboring block 100 to thereby form a long heat passageway. In other words, a plurality of the blocks manufactured at the above-mentioned input ratio through the above manufacturing method are connected with one another to install the hypocaust in such a way that the heat transfer holes are connected with one another, so that the heat passageway is formed in the entire floor evenly. The heat passageway may be in a zigzag form as shown in FIG. 4 or 5, but may adopt one of other forms.

However, when the blocks are connected with each other using the above construction method, there may be an interval to some degree at a connected portion between the connected blocks. Particularly, when the blocks are connected with each other in a state where the floor is not in a completely flat form, such a phenomenon may occur. Furthermore, even though the blocks are closely connected with each other in a relatively good state, there may be a need to strengthen the connection between the block to reinforce durability or sealability. In this case, it is preferable to fill up and paint the connected portion with paste 50. The paste can completely fill up the interval between the blocks while being hardened, whereby it provides excellent sealability and strengthen the connection between the blocks.

The paste 50 may be, for example, loess. That is, the paste 50 may be manufactured in such a way that loess of from 40% to 80% by weight and sand of from 20% to 60% by weight are mixed together. Water of a proper amount is added according to conditions or environments in order to knead the mixture. The paste is made of the constituent ingredients of the heating block excepting gravel and plaster. The reason is that the paste serves only to fill up the interval between the blocks.

[industrial Applicability]

As described above, if the heating blocks according to the present invention are used, anyone can easily embody the

Korean hypocaust-type heating system using traditional construction materials, such as loess. Moreover, the heating blocks according to the present invention can be widely used in the general heating field without any restriction to materials or heating methods.
