2. Description of the Related Art The level of housing in Japan has been improved year by year by the continuous efforts of housing manufacturers trying to meet various needs, and high-performance houses, such as highly airtight and highly insulated houses, have been provided. In addition to the conventional house that earns only the number of rooms by dividing it into small parts as in the past, many houses with large and large spaces have been built, and the air conditioning and heating facilities have been enhanced accordingly. Demands have increased, and a wide variety of air conditioning systems and air conditioning systems have been developed and provided.

A large living room, which is maximized by integrating a living room, a dining room and a kitchen, is used in many houses as an architectural design that emphasizes the connection of living spaces. Focusing on, it is a structure that always requires cooling and heating to an unnecessary space, and in order to perform efficient cooling and heating, circulators and cycle fans are used to circulate indoor air evenly and maintain a uniform room temperature Ingenuity was required.

[0004] Furthermore, among people who want to save energy, maintain a clean air in the room, and suppress the occurrence of mites and molds to live a healthy life, consider introducing a floor heating system capable of realizing head and foot heat. Although there are many people, floor heating systems that require a special underfloor structure require construction from the foundation of the house, and the heating materials used are expensive or In the case of circulating hot water with a large amount of heat storage, the facilities are also large, such as large-scale facilities.
It is the current situation that the installation has to be forcibly terminated.

On the other hand, if you look outside, in the climate of Japan that changes variously throughout the four seasons, snowfall is one of the most influential on daily life, especially in Hokkaido, Tohoku, Hokuriku region, etc. In snowy areas such as those mentioned above, it is necessary to spend a large amount of money and manpower every year on daily snow removal, transportation and disposal of snow removal, spraying of snow melting agent, etc. Sprinkling snow may be performed to reduce the labor costs required for transportation, the maintenance costs of snow removal equipment, and the costs of purchasing snow melting agents.However, pumping groundwater, roads and other passages Sprinkling water and melting snow on roads and other surfaces through pipes buried in parking lots and other facilities requires large facilities, requires a large amount of construction cost, and pumps up a large amount of groundwater. Arising Fear There is also, for modern society interruption of activity even though, even for a day even if is hindered, inexpensive,
Development of effective outdoor snow melting equipment that enables quick construction,
Practical application is an urgent issue.

[0006] Furthermore, as a problem related to the shortage of garbage disposal facilities, which has become a serious social problem, the disposal of garbage disposal equipment for each household in the disposal of garbage generated from daily life of people is another problem. There are many technologies to reduce the amount of garbage discharged from each household and reduce the weight by installing and using it to dry garbage or to decompose garbage using microorganisms. In order to promote the widespread use of garbage disposal equipment that employs such technology, subsidies have been provided to purchasers of garbage disposal equipment in many municipalities in Japan. Efforts have been made to suppress the generation of dust from various directions, for example.

The present invention quickly focuses on the necessity of a heat generating device capable of universally solving various problems such as indoor heating, snow melting outdoors, garbage disposal, and the like. We started research on heating elements that can be easily manufactured, examined the possibility of heat generation for all materials that are relatively inexpensive, and accumulated long-term trial and error and numerous trial production experiments. This time, finally, we succeeded in completing a rice husk cement block for heat generation with a new structure that combines basic technology that can achieve all the intended purposes, and the possibility of its practical use has been established, In the following, together with an embodiment representing the present invention shown in the drawings,
The configuration will be described in detail.

[0008]

DETAILED DESCRIPTION OF THE INVENTION As can be clearly understood from the embodiment shown in the drawings, which is representative of the present invention, the rice hull cement block for heat generation included in the present invention is basically a cement / paddy having a specific mixing ratio. An electrode plate is attached to each of the side wall surfaces of the predetermined thickness block body formed using the shell kneaded material and the other side wall surface opposite to the side wall surface, and a predetermined voltage can be applied between the electrode plates The gist of the present invention is a configuration formed in the above.

Specifically, the ratio of the volume of dried rice husk to the cement used is regulated so as to be a mixing ratio of approximately 1: 1 to 1: 3, and the water cement ratio is approximately 40 to 60.
% Of cement paste mixed with a predetermined amount of dried rice hull in a cement paste suppressed to a range of about
The cement / rice husk kneaded material is pressurized and cured within a compression ratio of 1.1 to 1.4 to form a block having an appropriate thickness, while being relatively opposed to one side wall surface and the side wall surface of the block body. An electrode plate is attached to each of the other side wall surfaces and integrated, and each electrode plate is preliminarily provided with a wiring capable of applying a predetermined voltage between both electrode plates, or Is a heating rice hull cement block having a configuration in which connection terminals are provided and wiring is possible via the connection terminals.

More specifically, the ratio of the volume of dried rice husk to the cement used is regulated so as to be a mixing ratio of approximately 1: 1 to 1: 3, and the water-cement ratio is approximately 40 to 60. % And a predetermined amount of dried rice hulls are mixed with the cement paste and stirred to form a kneaded mixture of cement and rice hulls.
An electrode plate is adhered to each of one side wall surface and the other side wall surface opposite to the side wall surface of the block body while applying pressure and curing within a range of 1 to 1.4 to form a suitably thick block body. After being attached and integrated, each electrode plate is provided with a wiring capable of applying a predetermined voltage between both electrode plates in advance, or connection terminals are provided respectively, and the connection terminals are provided. It is formed in such a way that it can be wired through, and according to the impregnation rate of water or electrolyte solution in the block body, the state of conduction between the electrode plates applied under a predetermined voltage is controlled, and the block body generates heat or generates heat It is a rice husk cement block for heat generation whose gist is a configuration to stop.

The cement functions not only as a base material for maintaining the shape of the block, but also as a heating element that generates heat when a voltage is applied thereto, and provides good curing and energization. If you use ordinary Portland cement that can generate heat due to, it will fulfill the required function sufficiently, but besides, early strength Portland cement, ultra early strength Portland cement,
Moderate heat Portland cement, sulfate resistant Portland cement, blast furnace cement, silica cement, or any of fly ash cement, etc., can be used.In particular, excellent in chemical resistance, hot springs, sewage, It is desirable to use sulfate-resistant Portland cement, blast furnace cement, silica cement, fly ash cement, etc., which are often used in places that come into contact with seawater and can withstand chemical reactions caused by the application of voltage for a long time. .

The dried rice hulls have not only a function as an aggregate but also a function as a resistor for suppressing the occurrence of overcurrent at the time of energization. After the cut rice is dried appropriately, the rice is crushed. Brown rice is removed and the remaining rice hulls do not need to be subjected to any special processing.However, when kneading with cement, if the dry state is too strong to knead easily with cement paste, etc. Water may be added to the cement in the state after kneading the dried rice hulls, and the cement paste may be easily blended into the surface of the dried rice hulls and uniformly mixed.

The bulk volume ratio of the cement to the dried rice hull is in the range of approximately 1: 0.5 to 1: 3.5 in order to function as a block for securing desired strength and conductivity. If the cement is too large, exceeding the above ratio, a porous structure that can ensure sufficient impregnation with water or an electrolyte solution cannot be obtained, and the ratio of dry chaff is If it is too large, it will not be possible to secure sufficient solidification to maintain the block shape, and it will be brittle, easily chipping and cracking. About 1: 1
A mixing ratio of about 1: 3 is desirable, and in order to ensure the highest strength and a sufficient porous structure, it is preferable to mix at a ratio of about 1: 1.5.

If the water-to-cement ratio is too much relative to the amount of cement, not only does it take a long time to cure, but it also hardens, hardens, becomes brittle, and does not withstand use. Even if the amount is too small, a sufficient connecting structure cannot be obtained, and it becomes difficult to maintain the shape of the block. Therefore, in order to cure a block that can withstand practical use, the water-cement ratio is in the range of about 35 to 65%. The water-cement ratio should be appropriately adjusted within an optimal range of about 40 to 60% according to the moisture absorption or drying state of the dried chaff.

If the cement-rice hull kneaded material is not pressurized at a predetermined compression ratio during curing, due to the elasticity of the dried rice hull, sufficient strength cannot be secured after hardening. Is too high, a sufficient porous structure of dried rice hulls cannot be obtained, and the inside of the block cannot be sufficiently impregnated with water or an electrolyte solution. It is necessary to pressurize so as to obtain a ratio.

The block body has a function as a structure having a predetermined durability, and also has a function as a heating element that generates heat when a voltage is applied. An electrode plate for receiving power supply is provided on each of the side wall surface and the other side wall surface opposite to the side wall surface, and the electrode plate has a connection terminal for connecting a cord connected to an external power supply. Must be provided or be directly wired so that they can be connected to an external power supply, and if necessary, sealed in an enclosure made of an electrically insulating material so as to have a watertight structure. It is possible that

The block body must have a porous structure in which dried rice husks are mixed, and must have a structure that can relatively easily impregnate water, an electrolyte solution, and the like, and have an electric resistance or electric conductivity corresponding to a desired calorific value. In addition to being able to select and impregnate water or electrolyte solution, the water or electrolyte solution contained in the object to be heated penetrates into the block and energizes, and the object to be heated is heated and dried. As the amount of water and electrolyte solution (and impregnation rate) absorbed by the block decreases, the calorific value also gradually decreases, and when the object to be heated is completely dried, the water and the electrolyte solution in the block may decrease. It is also possible to configure so as to evaporate and automatically stop energization.

Further, the shape of the block body can be freely set according to the object to be heated and the device to be employed. For example, as shown in an embodiment described later, when a rotary dryer is formed, In addition to being able to be a block having a bottomed cylindrical shape, it is also possible to form an uneven shape on the surface of the block to enhance heat exchange efficiency, and furthermore, placing a flowerpot, a planter or a water tank, etc. When used as a heating device, it is also possible to form a fitting-shaped portion on the upper surface such that the bottoms thereof are fitted and fixed.

The electrolyte solution is a liquid which has good electric conductivity and does not hinder the permeability to the cementitious component and the rice hull. The function is to increase the electrical conductivity of the electrolyte, and to shift from a non-energized state during drying to an energized state according to the degree of impregnation, and the electrolyte solution can be easily formed even at a relatively low voltage. A solution capable of generating heat,
For example, calcium hydroxide solution, sodium chloride solution,
It is convenient to adopt a sodium carbonate solution or the like.

The electrode plate functions as an electrical connecting part for applying a voltage to the block body, is made of an electrically good conductor, and has one side wall surface of the block body and the other side wall surface facing the same side wall surface. It is necessary to provide a joint area as large as possible, for example, a metal plate such as copper or stainless steel cut into a shape corresponding to the side wall surface. It is also possible to adopt a structure in which the screw is connected to the block using a plurality of screws, or to use a metal foil and bond and bond the block to the block using an electrically conductive adhesive.

The outer shell functions as an enclosure which covers the block body in an electrically insulated state and has a watertight structure, and enhances the durability, texture, and reliability of the watertight structure as necessary. Must be formed as
For example, when used for indoor floor heating, it is desirable to cover with relatively soft synthetic resin, rubber, etc., and to some extent, such as an outdoor garden, approach or parking lot. When used in a snow melting device installed in a place where strength is required, it should be a case made of metal or ceramic on which an insulating film is formed.

In addition to the above-described structure, the block body of the present invention is provided with a temperature sensor incorporated in an appropriate position on the heat generating surface, and controls the applied voltage based on the temperature detected by the temperature sensor. It is also possible to open or close the energized state, for example, using a thermistor, a thermocouple, a switch using a bimetal, or a shape memory alloy, or various other temperature sensors having equivalent functions. be able to.

Further, the temperature sensor may be separately assembled at a position distant from the block body to operate by detecting radiant heat. In addition, the temperature sensor is heated by touching the block body. Detects the heat transferred with convection to gas, liquid, etc., or the heat transferred to a solid object in contact with the block body, and controls the voltage and / or energization applied to the block body based on this. You can also.

Note that even if these temperature sensors are not incorporated, any outer shell is used, for example, for snow removal on the porch surface of the entrance, or the approach, the stairs, the walkway surface of pedestrians, etc. In the case of blocks that are not covered and are electrically connected as a whole, snow begins to fall on the surface of these blocks and is automatically applied with naturally melted snowmelt water, generating heat and conversely, falling snow It is also possible to control the heat generation by a system in which the voltage is lowered as the air stops and naturally evaporates due to heat storage and the outside air to become a dry state, and finally the energization is stopped.

The rice hull cement block for heat generation included in the present invention can be used, for example, for indoor heating by attaching it to a floor or wall of a house, or can be provided on furniture such as a chair to provide a heating appliance. It can be used for snow melting by laying it on roofs, parking lots, garden approaches or roads, etc.In addition, it can be installed on the inner wall of a water tank as a water heater, agricultural or horticultural plastic greenhouse, nursery, Installed in flower pots, planters, etc. to raise the soil temperature, room temperature or cultivation temperature, or as a form for concrete placement, which also has a function of keeping heat during concrete curing, or for clothes or It can be used as a heat source for any use where a relatively low temperature is sufficient, such as application to a heat source portion of a garbage processing dryer. In the following, the structure will be described in detail, together with some embodiments representative of the present invention shown in the drawings.
