Description

APPARATUS FOR DRYING HUMAN EXCREMENT OF

TOILET

Technical Field

[1] The present invention relates to an apparatus for drying human excrement of a toilet, and more particularly, to a toilet human excrement drying apparatus of an improved form which can enhance user's conveniences, in which water in excrement is more quickly removed to naturally dry excrement fast, and foul air in a septic tank is rapidly discharged to thus suppress occurrence of an offensive odor or smell, and avoid excrement from being exposed to the lower side of a toilet stool at maximum. Background Art

[2] As is well known, if a septic tank is filled with a certain amount of excrement, etc., in the case of a movable type toilet which is not a water rinsing type toilet which is connected to a sewerage system or a conventional type toilet having a septic tank which is laid under the ground, the excrement, etc., is collected using a septic tank lorry, and then the collected excrement, etc., is buried at a particular place or the excrement, etc., itself is purified and dried to then be recycled into compost. Otherwise, the excrement, etc., which is not purified is mixed in a fertilizer to then be used in compost production.

[3] However, such a method of treating excrement using a septic tank lorry has a shortcoming of increasing expenses to be incurred by use of septic tank lorry individually, and a shortcoming of increasing an economic cost to secure space and purification processing facilities for treating night soil of excrement etc., that is not purified after collection of excrement, on the whole.

[4] In particular, as being the case, if night soil of excrement etc.. that is not purified is discharged in a sewage system as it is, a problem of polluting environment becomes severe.

[5] As an idea improving these problems, a movable type toilet excrement drying apparatus was developed and filed by the same applicant as that of this application.

[6] The movable type toilet excrement drying apparatus is illustrated in FIG. 1, which was filed on March 21, 2002 by the same applicant, and registered as Korean utility model registration No. 0279600 on June 12, 2002.

[7] Referring to FIG. 1, a movable type toilet excrement drying apparatus includes: a toilet stool 32 formed in the lower end portion of the inside 20 of the toilet; an excrement storage unit 48 which is located below the toilet stool 32 and stores excrement 50 produced in the toilet stool 32; a dry plate 38 which are obliquely formed and having temporary stoppers 36 so that excrement 50 which drops down to the lower side of the toilet stool 32 flows down along the excrement storage unit 48 and then dried; a delay dry plate 40 which is located in zigzag form and is spaced at a certain distance from the lower portion of the dry plate 38 and having temporary stoppers 42 so that the flowing excrement 50 flows down with delay and then dried; a solar heat absorption plate 30 which is formed in a side to raise the internal temperature of the excrement storage unit 48 by the solar heat; a heating light bulb 28 having a temperature sensor 29 which is formed to heat the inside of the excrement storage unit 48 when there is no operation of the solar heat absorption plate 30; and a discharge unit 24 having a compulsive blowing fan 34 which is formed to discharge water and smell in the excrement storage unit 48.

[8] Also, the dry plate 38 and the delay dry plate 40 can be formed in pluralities in a zigzag form subsequently downwards.

[9] The excrement 50 produced in the toilet is dried to then be used as compost in the movable type toilet excrement drying apparatus. In this way, since the excrement 50 is composted in the movable type toilet excrement drying apparatus, a problem of contaminating the natural environment by making the excrement 50 flow down through the sewage etc., can be prevented beforehand.

[10] However, the filed movable type toilet excrement drying apparatus has a shortcoming that an application scope is limited to only the movable type toilet.

[11] That is, in the case of a fixed type toilet or a conventional type (or old-fashioned) toilet that the excrement storage unit 48 (or a septic tank) is laid under the ground, there is a restriction to install a solar heat absorption plate 30 which can absorb solar heat. Accordingly, there is a shortcoming that it is hard to apply the filed movable type toilet excrement drying apparatus in various kinds of toilets.

[12] In the filed movable type toilet excrement drying apparatus, transparent glass or tempered glass is used as the solar heat absorption plate 30 in order to receive light.

[13] Therefore, because the inside of the excrement storage unit 48 can be seen through from the outside, and thus the night soil of excrement 50 etc., is seen from the outside, there is a shortcoming of giving abhorrence to users and neighboring people.

[14] In particular, in the case of the movable type toilet excrement drying apparatus, there is a shortcoming that an effect of discharging water and smell to the outside drops when only wind blowing from the outside is used in a vane formed in the discharge unit 24 though it is desirable that water and smell is discharged smoothly to the outside in a dry process of excrement 50.

[15] Of course, a compulsive blowing fan 34 is provided in the discharge unit 24 in order to countermeasure an occasion that there is no wind. The compulsive blowing fan 34 has been described as having a structure that senses rotation of a vane in order to be turned on/off. However, in this case, the actual installation structure becomes complicated. Also, since the compulsive blowing fan 34 is installed in the discharge unit 24, the components included in the blowing fan 34 can be easily corroded in the process that water and smell such as ammonia gas or methane gas are exhausted through the discharge unit 24. As a result, the efficiency of the compulsive blowing fan 34 may drop.

[16] Accordingly, the same applicant as that of the present invention obtained Korean utility model registration No. 0370677 on December 07, 2004, entitled "Toilet excrement drying apparatus" in order to supplement a conventional technology.

[17] Thanks to this technology, an excrement drying apparatus that is used only in the conventional movable type toilet can be more commonly applied to a general toilet including a fixed type toilet. Further, the ventilation function of the existing toilet is strengthened through a structural reform of discharging foul air of the septic tank 48 to the outside more smoothly, to thereby seek conveniences in use.

[18] However, in the case of the above-described technology, a relatively lot of water is contained in the excrement 50 accumulated in the septic tank 48. Accordingly, it takes a lot of time substantially to naturally dry the water contained in the excrement 50. As a result, there is a shortcoming that the above-described technology lacks in discharging foul air of the septic tank 48 rapidly and removing an offensive odor or smell in the toilet.

[19] Also, in the case of all the above-described technologies, the dry plate 38 or the delay dry plate 40 which plays a role of delaying a flow of the excrement 50 is exposed to the lower side of the toilet stool 32, and the excrement 50 is accumulated on the upper surface of the dry plate 38 or the delay dry plate 40 for a given time or a given period. As a result, from the users' standpoint, the septic tank 48 appears to be filled with excrement 50.

[20] Therefore, from the users' standpoint, users may be unpleasant actually. Thus, there is a shortcoming that user's conveniences drop.

[21] As a result, in addition to the previous Korean utility model registration No.

0370677, this applicant reached to propose a toilet excrement drying apparatus of an improved form that can increase user's conveniences in which by removing water from excrement 50 more quickly and drying the excrement 50 more quickly and naturally, as well as discharging foul air of the septic tank 48 rapidly to thereby suppress an offensive odor or smell from occurring, and avoiding excrement 50 from being exposed to the lower side of the toilet stool 32 at maximum. Disclosure of Invention Technical Problem [22] Therefore, in order to supplement the shortcoming of the conventional art, it is an object of the present invention to provide a toilet human excrement drying apparatus of an improved form that can increase user's conveniences by removing water from excrement more quickly and drying the excrement more quickly and naturally, as well as discharging foul air of the septic tank rapidly to thereby suppress an offensive odor or smell from occurring, and avoiding excrement from being exposed to the lower side of a toilet stool at maximum.

[39] The present invention provides an apparatus for drying human excrement of a toilet, the toilet human excrement drying apparatus comprising: a toilet stool which is provided in the toilet; a septic tank which is located in the lower side of the toilet stool, in order to store excrement input through the toilet stool; a ventilation unit which comprises a ventilator whose one end communicates from the septic tank and other end is mounted to be exposed to the outer side of the toilet, to ventilate the inner portion of the septic tank, and which is provided in a discharge unit located at the upper one side of the toilet, a reflective mirror which is provided in an inner wall of the toilet so that sun light which is incident through transparent glass which is provided adjacent to the ventilator can be irradiated into the septic tank, and a greenhouse which is provided in the outer surface of the toilet to provide greenhouse effect; and an excrement drying member which is provided in the septic tank and doubles dry of water for excrement based on action of the ventilation unit, wherein the excrement drying member is a non- woven cloth, and is detachably combined with at least one side of the inner wall of the septic tank. Mode for the Invention

[40] Hereinbelow, a toilet excrement drying apparatus according to an exemplary preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

[41] FIG. 2 is a schematic configurational diagram illustrating a movable type toilet excrement drying apparatus according to a first exemplary embodiment of the present invention. FIG. 3 is a schematic perspective view of a septic tank in a toilet excrement drying apparatus illustrated in FIG. 2. FIG. 4 is a plan view illustrating a combined state of FIG. 3. FIG. 5 is a configurational diagram illustrating an example of a ventilation tube which is applied in the toilet excrement drying apparatus of FIG. 2.

[42] As illustrated in FIGS. 2 through 5, a toilet excrement drying apparatus according to an exemplary embodiment of the present invention basically irradiates sunlight into a sealed septic tank 200 of a toilet and thus reduces a drying time period of excrement 500 at maximum by this sunlight (solar heat). Simultaneously, microbial activities are very active in the septic tank 200 due to the sunlight to thereby activate decomposition of excrement 500 and thus remove an offensive odor and smell.

[43] In particular, an offensive odor or smell due to various factors such as water and ammonia gas, and methane gas which is generated in a drying and decomposition process of excrement 500 is exhausted more easily and quickly. Accordingly, ventilation of the inside of the toilet can be performed more smoothly to thereby increase user's conveniences.

[44] Of course, in addition thereto, remnants of excrement 500 whose decomposition proceeds can be composted through a post-processing work.

[45] Also, the toilet excrement drying apparatus according to the present invention can be applied in an ordinary movable type toilet (see FIG. 2) which is not a water rinsing type toilet which is connected with a sewerage system, and a fixed type (or old- fashioned type) toilet (see FIG. 7) having a septic tank 200 which is laid under the ground.

[46] Referring to FIGS. 2 through 5, but referring to FIG. 2 mainly, a movable type toilet in which an excrement drying apparatus according to an exemplary embodiment of the present invention is applied, generally includes a cabinet 100 which a user comes in and out, a toilet stool 101 which is provided at the bottom of the cabinet 100 to allow the user to go to stool, and a septic tank 200 of a fixed volume which is located in the lower side of the toilet stool 101 and which stores night soil such as excrement or urine (hereinafter referred to as excrement 500).

[47] In addition to these, the movable type toilet in which the excrement drying apparatus according to the exemplary embodiment of the present invention is applied further includes a ventilation unit 400 which is provided as a unit for keeping the inside of the toilet clean by removing an offensive odor or smell due to various factors such as ammonia gas and methane gas which is generated in a drying and decomposition process of excrement 500 stored in the septic tank 200.

[48] Referring to FIG. 2 and 5, the ventilation unit 400 will be described below. The ventilation unit 400 is mostly composed of a hollow ventilation tube 415 whose inner portion is empty. A discharge unit 401 is formed in the upper end portion of the ventilation tube 415, and an opening 402 is formed in the lower end portion thereof. In this manner, the ventilation unit 400 communicates from the inside of the septic tank 200.

[49] In the case of this exemplary embodiment, the ventilation tube 415 is formed of a tubular body having a circular cross-section. However, the ventilation tube may be formed of a multi-angular cross-sectional structure (not shown) including a rectangular cross-sectional or triangular cross-sectional structure.

[50] A ventilator 440 is provided in the discharge unit 401 which is formed in the upper end portion of the ventilation tube 415 as a means for more effectively performing a ventilation function (for example, a foul air discharge function of exhausting an offensive odor or smell in the septic tank 200) through the ventilation tube 415.

[51] The ventilator 440 is a kind of an air exhauster which is rotated by wind or particular power. Therefore, in the case of this exemplary embodiment, the ventilator 440 may be embodied by employing any one of a non-electric power ventilator which is rotated by wind or an electric power ventilator which is rotated by electric power supplied from a power supply. More preferably, but not necessarily, a ventilator 440 which combines a non-electric power function and an electric power function, may be used.

[52] That is, in the case that the ventilator 440 which combines a non-electric power function and an electric power function is used, the ventilator 440 operates to rotate by wind, that is, non-electric power when wind blows much, and the ventilator 440 operates to rotate by electric power supplied from a particular power supply, when wind does not blow or feeble wind blows. In this way, a ventilation state or function of the inner portion of the toilet and the septic tank 200 can be always kept to a certain fixed level more effectively.

[53] Here, as a method of supplying electric power to the ventilator 440 so as to rotate by electric power, a user can supply electric power to the ventilator 440, according to need, but the ventilator 440 is automatically energized or de-energized, that is, activated or deactivated. The latter electric power supplying method is more preferable.

[54] That is, in the case that the ventilator 440 operates at a preset speed of revolution or lower, a sensor (not shown) senses that the ventilator 440 operates at a preset speed of revolution or lower, and a controller (not shown) controls the ventilator 440 to be turned on/off based on the sensed result. This structure can be easily embodied with a sensor which senses strength of wind and a controller which runs the ventilator 440 based on action of the sensor. Thus, the detailed description thereof will be omitted below.

[55] Transparent glass 410 is mounted in the lower portion of the ventilator 440, that is, in the upper portion of the ventilation tube 415. The transparent glass 410 plays a role of making the sunlight (solar heat) enter the inside of the ventilation tube 415.

[56] The transparent glass 410 can be installed in a corresponding area in the upper portion of the ventilation tube 415, after being separately manufactured, or can be integrally formed with the ventilation tube 415 into one body. In the latter case, the ventilation tube 415 is made of glass or plastic of a transparent quality of a material. In this case, since the upper area itself of the ventilation tube 415 is made of the transparent glass 410, it is more effective to make the sunlight enter the ventilation tube 415.

[57] Height and size of the transparent glass 410 can be designed considering an external environment in which the ventilation tube 415 is installed, diameter of the ventilation tube 415, etc. Only, with a viewpoint to consider at design, it is enough to design the transparent glass 410 to have size and arrangement which can allow a more amount of sunlight to enter the ventilation tube 415 for a unit of time even if the ventilation tube 415 is installed at a restricted space.

[58] A reflective mirror 420 is provided in the inner wall of the ventilation tube 415, in order to receive sunlight which enters the ventilation tube 415 via the transparent glass 410 and then provide radiant heat, and simultaneously reflect the sunlight to then be irradiated into the inside of the septic tank 200.

[59] In order to make a more amount of sunlight irradiated into the septic tank 200, so that excrement 500 is dehydrated or dried in the septic tank 200, it is advantageous that the reflective mirror 420 is installed all over the inner wall of the ventilation tube 415.

[60] However it may be enough if the reflective mirror 420 is installed all over the inner wall of the ventilation tube 415, the number and area, and the arrangement structure of the reflective mirror 420 can be variously modified if sunlight can be irradiated into the septic tank 200 through the lower opening 402 of the ventilation tube 415.

[61] Judging from a method of installing the reflective mirror 420, in the case that the reflective mirror 420 is installed in the inner wall of the ventilation tube 415, the ventilation tube 415 is manufactured into a state where the ventilation tube 415 is divided into at least two parts. Then, the reflective mirror 420 is installed all over the inner wall of the ventilation tube 415. Finally, the reflective mirror 420 can be installed in the ventilation tube 415, in a manner that the reflective mirror 420 is combined with the separated ventilation tube 415 using a welding or bonding technology.

[62] In this way, the ventilation tube 415 can be manufactured in various forms under a certain specification. That is, the ventilation tube 415 can be variously designed selectively according to a given environment under which the ventilation tube 415 is installed.

[63] Of course, instead of providing the separate reflective mirror 420 in the inner wall of the ventilation tube 415, as in this exemplary embodiment, the inner wall itself of the ventilation tube 415 can be designed to play a part of the reflective mirror 420.

[64] In the case that the inner wall itself of the ventilation tube 415 is used as the reflective mirror 420 as described above, the ventilation tube 415 is made of a material of tempered glass etc., in which an opaque film can be coated on the outer circumferential surface of the ventilation tube 415.

[65] A greenhouse 430 is further provided in a part of the outer side of the ventilation tube 415 and is installed in a sealed state via transparent glass 431 to thereby provide a greenhouse effect.

[66] The greenhouse 430 heats the inside of the ventilation tube 415, so that the internal temperature of the ventilation tube 415 can increase more quickly and effectively, to thereby promote natural convection due to a temperature difference between the inside and outside of the ventilation tube 415 and thus play a role of an auxiliary ventilator which assists the ventilation tube 415 to perform smooth ventilation. That is, the greenhouse 430 has a structure that sunlight can permeate and derive the internal temperature of the ventilation tube 415 to rise up through the greenhouse effect.

[67] The greenhouse 430 can be implemented using a material of a vinyl quality whose greenhouse effect is very excellent when sunlight permeates. However, any material may be used in the greenhouse 430 if it provides a greenhouse effect.

[68] Here, if an excellent greenhouse effect can be obtained in the case that the greenhouse 430 is fabricated using a vinyl quality of a material, the greenhouse 430 itself may be easily damaged or broken by an external force. Therefore, the greenhouse 430 is preferably but not necessarily made of a quality of a material playing a role of increasing the internal temperature of the ventilation tube 415 and having a certain durability which can endure an external force, for example, transparent glass 431 such as tempered glass.

[69] By the structure of the ventilation unit 400, the external sunlight passes through the transparent glass 410 located on the upper portion of the ventilation unit 400, and is incident to the inside of the ventilation tube 415. Then, the incident sunlight is reflected by the reflective mirror 420 in the ventilation tube 415, and can be irradiated to the inside of the septic tank 200 through the opening 402. [70] That is, if sunlight enters the inside of the ventilation tube 415 through the upper transparent glass 410 of the ventilation tube 415, the sunlight is delivered in the whole inside of the ventilation tube 415 by the reflective mirror 420 which is installed all over the inner wall of the ventilation tube 415. Accordingly, the sunlight is delivered into the septic tank 200 through the lower opening 402 of the ventilation tube 415.

[71] In this way, if the sunlight is delivered into the septic tank 200 through the ventilation tube 415, the internal temperature of the inside of the septic tanks 200 rises up by the sunlight (that is, the solar heat). Simultaneously, microbial activities are very activated in the septic tank 200 due to the sunlight to thereby enhance a drying efficiency of excrement 500 and accelerate a decomposition speed of excrement 500.

[72] Also, various kinds of offensive odor such as ammonia gas and methane gas which is generated in the process of drying excrement 500 is exhausted to the outside through the opening 402, the ventilation tube 415, the discharge unit 401 and the ventilator 440, to thereby make a more comfortable toilet.

[73] In more detail, if sunlight enters the inside of the ventilation tube 415 through the transparent glass 410 which is provided in the upper portion of the ventilation tube 415, the sunlight is delivered in the whole inside of the ventilation tube 415 by the reflective mirror 420 which is installed all over the inner wall of the ventilation tube 415. Accordingly, the inside of the ventilation tube 415 is heated by the solar heat. Simultaneously, the greenhouse 430 which is formed at the outside of the ventilation tube 415 receives the sunlight (that is, the solar heat) and heats the inside of the ventilation tube 415 by the greenhouse effect. As a result, the heated air in the ventilation tube 415 rises up to then be exhausted to the outside of the ventilation tube 415.

[74] As a result, a natural convective flow through the ventilation tube 415 occurs actively due to a temperature difference between the ventilation tube 415 and the septic tank 200 and a pressure difference in the ventilation tube 415 after the internal air of the ventilation tube 415 has been exhausted to the outside, to thereby discharge foul air in septic tank 200 more smoothly to the outside.

[75] In particular, since the ventilator 440 which is installed in the upper end of the ventilation tube 415 rotates by a non-electric power by wind or rotate by electric power, foul air in the septic tank 200 can be easily discharged to the outside by operation of the ventilator 440, together with a natural convection phenomenon due to the temperature difference between the ventilation tube 415 and the septic tank 200.

[76] Thus, in the present invention, the inside of the ventilation tube 415 having the structural feature is heated to thereby mix a natural convection phenomenon due to the temperature difference between the ventilation tube 415 and the septic tank 200, and a compulsive discharge function (that is, a forced exhaust function) by operation of the ventilator 440. Accordingly, since foul air in the septic tank 200 can be easily discharged to the outside, a ventilation function can be strengthened more relatively in comparison with the conventional art.

[77] That is, the water and smell of excrement 500 in the septic tank 200 can be transpired through ventilation tube 415. Thus, external agreeable air can enter the inside of the toilet through air holes 700 which are installed in the upper portion of the cabinet 100. As a result, the inside of the cabinet 100 in the toilet becomes agreeable thereby preventing an unpleasant feeling in use of the toilet from being caused.

[78] Although an additional exhaust fan 450 is omitted in this exemplary embodiment, as illustrated in FIG. 6, the additional exhaust fan 450 may be installed in the ventilation tube 415. If the exhaust fan 450 has been installed and then is made to operate, an offensive odor in septic tank 200 must be exhausted to the outside more quickly.

[79] Meanwhile, referring to FIGS. 2 through 4, in order to double a ventilation function by the ventilation unit 400, an excrement drying member 230 is further included in the septic tank 200. The excrement drying member 230 plays a part of doubling a drying function for water of excrement 500, based on action of the ventilation unit 400.

[80] Various kinds of materials can be applied as the excrement drying member 230.

Non- woven cloth which is inexpensive and has an excellent effect can be applied as the excrement drying member 230.

[81] For reference, non- woven cloth is made in the form of a felt shape, in which fibers are arranged in parallel or in the undetermined direction without passing through a fabric cloth process, and then are combined with a plastic adhesive. At the beginning, cotton or viscose rayon is mainly used as a raw material for fibers. However, a synthetic fiber such as nylon has been used as non- woven cloth.

[82] A wet method and a dry method exist as a processing method. The wet method is called a dipping method, in which fibers are put into a plastic adhesive vessel and soaked to then be dried and thermally treated similarly to a paper processing method. The dry method spouts synthetic resin onto fibers formed of a thin cotton shape, and heats the fibers to then be dried.

[83] The non- woven cloth is specially excellent to adsorb water. Therefore, non-woven cloth is used to primarily absorb water mixed with excrement 500 in this exemplary embodiment.

[84] However, since non- woven cloth is relatively thin, it is necessary for the non-woven cloth to have hardness to a degree, after having been installed. For example, even though it has been installed as shown in FIGS. 2 through 4, the excrement drying member 230 which is non- woven cloth may escape a relevant position or drop down to the floor in the septic tank 200, by falling excrement 500. [85] Accordingly, when the excrement drying member 230 is formed of non-woven cloth, it is fabricated so as to have a predetermined thickness and have hardness at least to a degree. In the case that a number of excrement drying members 230 are used, the excrement drying members 230 need to be arranged so as to be appropriately regularly spaced from each another. Alternatively, it can be considered that a frame may be added to the outer block of the excrement drying member 230.

[86] Also, in order to replace the excrement drying member 230 at a given cycle, it is preferable that the excrement drying member 230 is detachably installed from the inner wall of the septic tank 200.

[87] In this exemplary embodiment, after brackets 232 are installed on the inner wall of the septic tank 200, the excrement drying members 230 are fitted into the brackets 232. Therefore, the excrement drying members 230 are simply installed to thereby suffic iently achieve the effects which can be obtained by use of the excrement drying members 230. Of course, unlike the illustration in the drawings, the excrement drying members 230 may be fixed and installed using a bolt coupling method.

[88] Meanwhile, In the case that the excrement drying member 230 is installed in the septic tank 200 as non- woven cloth, a single excrement drying member 230 may be used. However, considering a drying efficiency, it is preferable that numbers of excrement drying members 230 are used.

[89] If numbers of excrement drying members 230 are used, they may be arranged so as to be mutually spaced from each other, as is illustrated.

[90] Here, if the excrement drying members 230 which are manufactured equally with the width of the septic tank 200 divide the septic tank 200 into several sections perfectly, flow of air does not occur.

[91] Therefore, it is preferable that an area of an excrement drying member 230 is formed smaller than that of at least one side wall of the septic tank 200. Also, according to the structural features, it is preferable that a number of excrement drying members 230 are arranged in a zigzag form in the septic tank 200 so that flow of air which is directed toward the ventilation unit 400 is smoothly achieved, although many excrement drying members 230 may be installed. In FIG. 4, an air flow is illustrated as a two-dot-broken line.

[92] Also, the lower end portion of the excrement drying member 230 may contact the floor in the septic tank 200, or may be spaced by a given distance upwards from the floor of the septic tank 200.

[93] In the case that the excrement drying members 230 are placed in this way, water of excrement 500 is absorbed, and thus dry for a residual amount of excrement 500 is festinated, to enhance a drying efficiency. Therefore, decomposition for remnants of excrement 500 can proceed further actively. [94] A heating unit 600 which can heat the inside of the septic tank 200 is further provided in one side of the septic tank 200 in preparation for a case that the internal temperature of the septic tank 200 does not rise up since sunlight is not delivered into the septic tank 200 through the ventilation unit 400, for example, a case that the inside of the septic tank 200 cannot be heated by sunlight like the evening which is dark without sunlight or the rainy season which is rainy or cloudy. A heater or a lighting bulb may be used for the heating unit 600.

[95] The heating unit 600 is made to automatically operate in the case that it is sensed by a sensor 610 that the internal temperature of the septic tank 200 goes down to below a certain temperature, to thereby play a role of raising the internal temperature of the septic tank 200.

[96] The heating unit 600 is made to operate through a separate power supply. Also, since the heating unit 600 is a consumable which can be replaced after use for a predetermined time, it is preferable that the heating unit 600 is designed to be installed at a place in position that a user can replace it by a new one.

[97] Meanwhile, the toilet excrement drying apparatus according to the present invention can be applied according to a difference in the structural features between an ordinary movable type toilet (see FIG. 2) in which a septic tank is exposed to the outside, and a fixed type (or old-fashioned type) toilet (see FIG. 7) having a septic tank 200 which is laid under the ground.

[98] In the case of the movable type toilet illustrated in FIG. 2, a solar heat absorption plate 210 which can absorb solar heat is further provided on the exterior wall of the septic tank 200. In the case of the fixed type toilet of FIG. 7 that the septic tank 200 is laid under the ground, a solar heat absorption plate 210 cannot be structurally installed. Accordingly, the solar heat absorption plate 210 is not placed in the fixed type toilet.

[99] Therefore, in the case that the excrement drying apparatus according to the present invention is applied in the movable type toilet illustrated in FIG. 2, sunlight is naturally irradiated into the inside of the septic tank 200 through the ventilation tube 415 and excrement 500 can be naturally dried and decomposed. Simultaneously, a drying efficiency and a decomposition speed can be heightened through a function of the solar heat absorption plate 210. Thus, an application range or scope is expanded or broadened a little more.

[100] For reference, the solar heat absorption plate 210 is made of a translucent material or a transparent material, so that sunlight may be projected directly into the inside of the septic tank 200. Plastic or tempered glass is applied as the translucent material or the transparent material for the solar heat absorption plate 210 in addition to general glass. Of course, if the solar heat absorption plate 210 is formed with a perfectly transparent material, the inside of the septic tank 200 can be seen from the outside, to accordingly cause an unpleasant view. Therefore, it is preferable that the solar heat absorption plate 210 is made of a translucent material which makes the inside of septic tank 200 not seen well from the outside, and which allows the sunlight to enter the septic tank 200 and the heat of the sunlight to be introduced into the septic tank 200.

[101] In the movable type toilet illustrated in FIG. 2, an excrement removal door 220 is further provided in opposition to the solar heat absorption plate 210. The excrement removal door 220 plays a role of removing and drying water of excrement 500, and simultaneously collecting decomposed excrement 500 in the case that the septic tank 200 is filled with excrement 500 which is rotten and decomposed by microbes which are mixed in the excrement 500. For reference, decomposed excrement 500 may be removed after uncovering a separate cover of the toilet stool 101 in the case of the fixed type toilet of FIG. 7.

[102] As described above, the present invention provides a toilet excrement drying apparatus which can enhance user's conveniences, in which water in excrement 500 is more quickly removed to naturally dry excrement fast, and foul air in a septic tank 200 is rapidly discharged to thus suppress occurrence of an offensive odor or smell, and avoid excrement 500 from being exposed to the lower side of the toilet stool 101 at maximum.

[103] Although the exemplary embodiments of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited thereto.

[104] Although it is not described in the above-described exemplary embodiments, a dry plate may be further provided with a slope downwards in the lower end portion of a toilet stool like the technology disclosed in the previous application filed by the same applicant as that of this invention so that excrement is not fallen down straightly to the floor of a septic tank but is dried and decomposed slowly for long by sunlight irradiate into the septic tank, to then be moved.

[105] As described above, the present invention has been described with respect to particularly preferred embodiments. However, the present invention is not limited to the above embodiments, and it is possible for one who has an ordinary skill in the art to make various modifications and variations, without departing off the spirit of the present invention. Thus, the protective scope of the present invention is not defined within the detailed description thereof but is defined by the claims to be described later and the technical spirit of the present invention.

[106] As described above, a toilet human excrement drying apparatus according to the present invention provides an effect of enhancing user's conveniences, in which water in excrement is more quickly removed to naturally dry excrement fast, and foul air in a septic tank is rapidly discharged to thus suppress occurrence of an offensive odor or smell, and avoid excrement from being exposed to the lower side of the toilet stool at maximum.

Industrial Applicability As described above, a toilet human excrement drying apparatus according to the present invention can be used in the purification or compost production field of collecting and burying night soil such as excrement.
