  However, urine separated and stored from urine produces ammonia by oxidative decomposition of urea in the urine, and the produced ammonia volatilizes from the urine and scatters outside from the urine container, and the user of the toilet device Some people in the vicinity of toilet equipment may feel ammonia odor.

  The present invention has been made in view of the above problems, and an object thereof is to provide a toilet apparatus in which ammonia is hardly scattered to the outside.

A toilet apparatus according to the present invention includes a toilet that separates and discharges feces and urine, a urine container that stores urine discharged from the toilet, a first Peltier element that cools urine in the urine container, and a fecal container includes a stirring device for stirring the feces of the inner, the first Peltier element to cool the urine container one surface thereof, at its other face of that are disposed so as to heat the feces container.

According to this, since the urine in the urine container can be cooled, it is difficult to cause oxidative decomposition of urea in the urine container, and the amount of ammonia generated in the urine in the urine container can be reduced. Furthermore, since urine is cooled, volatilization of ammonia from urine can be suppressed. Therefore, the amount of ammonia scattered from the urine container is greatly reduced. In addition, the Peltier element has a sufficiently lower initial cost than a cooling facility using a refrigerant such as ammonia, chlorofluorocarbon, CO ₂ , the running cost can be made equal to or less, can be reduced in size and weight, and has high silence.
In addition , the feces and the like can be stirred together with a porous material such as sawdust in a state where the temperature of the feces and the like in the feces container is sufficiently high. Accordingly, the water content of feces can be reduced efficiently, and the activity of the bacteria can be enhanced to efficiently cause the decomposition and fermentation of the feces, so that processing such as composting of feces can be performed suitably. Further, by driving the first Peltier element, the heat removed from the urine container is used as heat for heating the stool treatment tank, so that the urine container and the stool container can be cooled efficiently. it can.

  Here, it is preferable to have a urine container sensor that measures a physical quantity in the urine container, and a control device that controls electric power supplied to the first Peltier element based on the physical quantity.

  According to this, the cooling degree of the urine in the urine container by the first Peltier element can be appropriately controlled based on the physical quantity in the urine container. Therefore, it is possible to suppress the cooling in the urine container from being insufficient or excessive cooling, and thus it is possible to suppress the amount of ammonia scattered efficiently.

  The urine container sensor preferably measures at least one of the temperature in the urine container and the ammonia concentration in the urine container as its physical quantity.

  For example, when measuring the temperature in the urine container, the first Peltier element can be controlled so as to maintain the temperature of the urine in the urine container within a desired range. Ammonia volatilization can be reliably suppressed. Here, from the viewpoint of sufficiently suppressing the generation and volatilization of ammonia, it is preferable that the first control means controls the power supplied to the first Peltier element so that the temperature of the urine in the urine container is 10 ° C. or less. It is more preferable to control the power so as to be 5 ° C. or lower.

  Further, for example, when measuring the ammonia concentration in the urine container, the cooling by the first Peltier element can be controlled so as to maintain the ammonia concentration in the urine container in a predetermined range. Therefore, the amount of ammonia scattered from the urine container can be reduced in an energy efficient manner according to changes in the usage state of the toilet apparatus.

  Here, when controlling the heat transfer capability of the first Peltier element so that the temperature in the urine container becomes a desired temperature, it may be difficult to maintain the temperature in the feces treatment tank at an arbitrary temperature.

  Therefore, it further includes a second Peltier element different from the first Peltier element, and a sensor in the stool container for measuring a physical quantity in the stool container. One of the peltier elements is provided on the basis of the physical quantity measured by the sensor in the urine container and the physical quantity measured by the sensor in the stool container. It is preferable to control the power supplied to the second Peltier element.

  According to this, since it further has a second Peltier element capable of either cooling the urine in the urine container or heating the stool in the stool processing tank, it is measured by the physical quantity in the urine container and the sensor in the stool container. By changing the driving ratio of the first Peltier element and the second Peltier element based on the physical quantity in the feces treatment tank, the temperature in the urine container and the state such as the temperature in the fecal container are individually Can be maintained within a predetermined range. Therefore, it is possible to suitably achieve both the reduction of the amount of ammonia scattered from the urine container, the reduction of the water content of the feces and the suitable fermentation and decomposition of the feces in the feces container.

  In addition, the fecal container sensor preferably measures at least one of the temperature in the fecal container, the concentration of odorous gas in the fecal container, and the moisture concentration in the fecal container as a physical quantity.

  According to these, the temperature in the feces container, the state of agitation, etc. can be suitably grasped, and accordingly, each Peltier element can be suitably controlled so that the processing in the fecal container is suitably performed. it can.

  Moreover, it is preferable to have a gas discharge means for discharging the gas in the stool container to the outside through the urine container.

  Thereby, the gas in the feces container is cooled in the urine container, and the moisture in the gas is condensed and removed. Therefore, since moisture is removed from the exhaust gas, when such a toilet apparatus is installed indoors, problems due to water vapor such as condensation can be reduced. Moreover, since the odorous gas generated from the feces when moisture is removed is also collected on the water side, the odor of the exhaust gas can be reduced.

  Moreover, it is preferable to have a porous material container in which the porous material is stored, and for the gas discharge means to further discharge the gas in the feces container to the outside through the porous material container.

  The porous material container is a porous material storage container to be supplied / supplemented in the feces container. Examples of the porous material stored in the porous material container include plant materials such as sawdust, straw, rice husk and coconut shell, and inorganic materials such as activated carbon and zeolite.

  Further, since the gas in the feces container is further discharged outside through the porous material container, the odorous gas in the discharged gas is adsorbed by the porous material, and the discharged gas is made more non-brominated. can do.

  Moreover, it is preferable to further have a solid discharge means for accommodating the contents in the feces container in the packaging container.

  According to this, the contents in the stool container can be packaged and disposed in a packaging container such as a paper pack without touching the hand, and a more sanitary toilet device can be used.

  Moreover, it is preferable to provide a pH adjusting device that adjusts the pH value of urine in the urine container to 3 to 5.

  According to this, since the pH of urine is maintained at an appropriate acidity, it is possible to further reduce the volatilization of ammonia from urine.

  According to the present invention, since the amount of ammonia scattered from the urine container of the toilet device can be reduced, the environment around the toilet device can be improved.

A screw-like stirring blade 50 extending horizontally is provided in the lower part of the feces treatment tank 30. The stirring blade 50 is rotated by a motor 52 provided on the side of the feces treatment tank 30. The stirring blade 50 stirs and mixes sawdust and excreted feces in the feces treatment tank 30.

  The feces treatment tank 30 is further provided with a solid discharge device 95 that discharges the contents 33 in the feces treatment tank 30. The solid discharge device 95 includes a rotary valve 90 that sends out the contents 33 in the feces treatment tank 30 to the outside, and a holding portion 93 that holds a packaging container 92 such as a paper pack. The contents 33 are accommodated in the packaging container 92 and discharged to the outside. The rotary valve 90 is provided at a position away from the opening 15 of the toilet 10, and fresh feces 3 supplied from the user 2 through the opening 15 are directly discharged to the outside through the rotary valve 90. It becomes difficult to be done. The screw-like stirring blade 50 is also rotated in such a way that the fresh stool 3 is not easily carried to the rotary valve 90 side.

  The porous material container 60 is a container in which sawdust 62 is stored, and is connected to the upper part of the feces treatment tank 30 through a supply valve 63.

  When the supply valve 63 is closed, the sawdust 62 is not supplied into the feces treatment tank 30. On the other hand, when the supply valve 63 is opened, sawdust 62 is supplied into the feces treatment tank 30 by a predetermined amount. The supply valve 63 is operated by a person or the like as necessary.

  The porous material stored in the porous material container 60 is not limited to sawdust 62 as long as it is porous, and plant materials such as straw, rice husk and coconut shell, inorganic materials such as activated carbon and zeolite, and the like can be used. Here, as a porous material, by using plant materials such as sawdust, straw, rice husks, coconut shells, and inorganic materials such as activated carbon and zeolite, treated feces can be sprayed as fertilizers in fields. . In addition, when the processing amount of the feces 3 in the toilet apparatus 1 is large, it is preferable to add activated carbon having a specific surface area higher than that of the sawdust 62 to the sawdust 62 and the like.

  And in this embodiment, the toilet apparatus 1 is equipped with the 1st Peltier element 40 in order to cool the inside of the urine tank 20, especially. The first Peltier element 40 is provided between the urine tank chamber 25 and the feces treatment tank 30. The cooling surface 40b of the first Peltier element 40 is in contact with the wall surface of the urine tank chamber 25, and the heating surface 40a opposite to the cooling surface 40b of the first Peltier element 40 is the wall surface of the feces treatment tank 30. Touching.

  In this first Peltier element 40, as shown in FIG. 2, a plurality of P-type semiconductors 41 and a plurality of N-type semiconductors 42 are alternately connected in series with electrodes 43, and these electrodes 43 are alternately arranged. The cooling devices are alternately arranged on the upper side and the lower side. And the heat conductive board 45 with favorable heat conductivity is provided on the electrode 43 arrange | positioned above, This surface is used as the cooling surface 40b. On the other hand, a heat conductive plate 45 having good heat conductivity is also provided on the electrode 43 arranged on the lower side, and this surface is a heating surface 40a. In the first Peltier element 40 of the present embodiment, the p-type semiconductor 41 and the n-type semiconductor 42 are supported by a holding member 48 such as a resin at the center in the thickness direction of the first Peltier element 40. As such a heat conductive plate 45, iron and an alloy plate containing iron as a main component, copper and a copper alloy plate containing copper as a main component, aluminum, various alloy plates containing aluminum as a main component, and the like can be used. Further, as the heat conductive plate 45, a metal plate having a surface plated with copper or the like may be used.

  When a direct current is passed through the first Peltier element 40, heat is transferred from the cooling surface 40b toward the heating surface 40a, the cooling surface 40b is cooled, and the heating surface 40a is heated. The heating surface 40a and the cooling surface 40b can be interchanged by changing the polarity of voltage application. According to such a first Peltier element 40, although depending on the temperature of the heating surface 40a, the temperature of the cooling surface 40b can be cooled to about −40 ° C.

  The first Peltier element 40 is connected to the controller 80. The thermometer 27 is also connected to the controller 80. The controller 80 supplies a direct current from the power source 70 to the first Peltier element 40. At this time, the controller 80 controls the electric power that drives the first Peltier element 40, so that the temperature of the urine in the urine tank 20 is maintained within a predetermined temperature range from the cooling surface 40b to the heating surface 40a. The amount of heat transfer, that is, the cooling temperature of the cooling surface 40b is controlled.

  The controller 80 is connected to the agitation motor 52, and the controller 80 controls the driving of the motor 52 so that the contents 33 in the feces treatment tank 30 are agitated every predetermined time.

  Next, the effect | action in the toilet apparatus 1 which concerns on this embodiment is demonstrated.

  First, when the user 2 sits on the toilet 10 and excretes feces 3 and urine 4, the excreted feces 3 is supplied into the fecal treatment tank 30 through the opening 15 on the rear side of the toilet 10, The urine 4 is supplied into the urine tank 20 through the opening 14 on the front side of the toilet 10. Therefore, feces 3 are stored in the feces treatment tank 30 and urine 24 is stored in the urine tank 20. The urine 24 contains nutrients such as urea, potassium, and phosphorus, and 96% of the urine is water. In addition, since the urine 24 is sterile, it is difficult for biological rot and decomposition to occur by itself. On the other hand, the stool 3 contains digested products, undigested fibers, epithelial cells, and enteric bacteria that have been degraded by the enteric bacteria group. Here, in the toilet apparatus 1 of the present embodiment, the feces 3 separated from the user 2 and discharged from the urine 4 are separated and stored, so that the feces 3 and the urine 4 are mixed and become spoiled. It is difficult to cause proper decomposition.

  In the toilet apparatus 1 according to the present embodiment, the urine tank chamber 25 is cooled by the first Peltier element 40, so that the urine 24 in the urine tank 20 is cooled. Therefore, urea contained in the urine 24 in the urine tank 20 is not easily oxidized, and the amount of ammonia generated in the urine tank 20 is suppressed. Moreover, since the temperature of the urine 24 in the urine tank 20 is kept low, volatilization of ammonia from the urine 24 is suppressed. Therefore, the amount of ammonia emitted from the urine tank 20 to the outside of the toilet apparatus 1 can be reduced. Therefore, such a bad odor problem in the non-washing toilet can be suitably solved, and the toilet according to the present embodiment can be used for a toilet in an area where water is insufficient, an emergency toilet, a toilet for developing countries, and the like. Application of equipment is expected. In addition, in places where there is not enough water, that is, in general households, hospitals, and public facilities in developed countries, it becomes easier to adopt toilet equipment that does not generate such bad odors, and the water-saving effect is increased. There are many points that contribute to the construction of a resource recycling society.

In addition, the first Peltier element 40 has a sufficiently lower initial cost than a cooling facility using a refrigerant such as ammonia, chlorofluorocarbon, CO ₂ , the running cost can be equal to or less, and can be reduced in size and weight, and is quiet. Is also expensive.

  Furthermore, since the temperature of the urine 24 in the urine tank 20 is maintained at a predetermined low temperature by the thermometer 27 and the controller 80, the effect of suppressing the scattering of ammonia from the urine tank 20 is very high. ing. Here, in order to more reliably reduce the amount of scattered ammonia, the controller 80 preferably maintains the temperature of the urine 24 in the urine tank 20 at 10 ° C. or lower, and more preferably maintains it at 5 ° C. or lower. preferable.

  On the other hand, sawdust 62 is introduced into the feces treatment tank 30 from the porous material container 60 via the supply valve 62 in advance or appropriately during use. Then, by operating the stirring blade 50 at predetermined time intervals, the feces 3 and the sawdust 62 are stirred in the feces treatment tank 30, and the water of the feces is appropriately absorbed into the sawdust, and further, the sawdust is further removed. Aerobic bacteria grow efficiently as a carrier. Therefore, it is possible to ferment and decompose the feces to make the contents 33 as an organic matter having a reduced odor, volume reduction, and weight reduction. This organic matter can be used as an organic fertilizer. Note that the organic matter is sterilized by being placed in such a low moisture state for a predetermined period. Odor gas such as ammonia generated from feces is also adsorbed by sawdust.

  Here, in this embodiment, since the feces treatment tank 30 is heated by the heating surface 40a of the first Peltier element 40, the temperatures of the feces 3 and the sawdust 62 in the fecal treatment tank 30 are increased. Therefore, the water removal from the feces 3 in the feces treatment tank 30 is performed more suitably. Furthermore, by raising the temperature, the aerobic bacteria are propagated more efficiently, and the efficiency of fermentation and decomposition of the feces 3 is increased.

  Moreover, since the cooling surface 40b of the first Peltier element 40 cools the urine tank 20 and the heating surface 40a of the first Peltier element 40 heats the feces treatment tank 30, the heat removed from the urine tank 20 is increased. It will be given to the feces treatment tank 30, and energy efficiency can be made high compared with performing separately cooling and heating using a separate Peltier element.

  Further, the content 33 as an organic matter generated by decomposition and fermentation by the treatment in the feces treatment tank 30 is mechanically packaged in the paper pack 92 and discharged by the solid discharge device 95. 33 is less likely to spill, and the contents 33 can be processed more hygienically without touching. In addition, although the contents 33 after processing are sterilized by being decomposed and fermented, such an automatic discharge process is particularly effective when pathogenic bacteria or the like may remain. is there.

(Second embodiment)
Next, a toilet apparatus 101 according to the second embodiment will be described with reference to FIG.

  The first point in which the toilet apparatus 101 according to the present embodiment is different from the toilet apparatus 1 according to the first embodiment is that the second Peltier element 140 and a thermometer (sensor in the feces container) 57 are provided.

The second Peltier element 140 is provided on the lower surface of the urine tank chamber 25. Second While cooling surface 1 40b of the Peltier element 140 is in contact with the urine tank chamber 25, the heating surface 1 40a of the second Peltier device 140 has not been contact with the feces treatment tank 30, the second Peltier element 140 Is driven, only the urine 24 in the urine tank 20 is cooled, and the feces 3 and the like in the feces treatment tank 30 are not heated. The second Peltier element 140 is connected to the controller 80 and driven.

  Further, the thermometer 57 is provided in the feces treatment tank 30 and measures the temperature of the contents in the feces treatment tank 30. The thermometer 57 is connected to the controller 80.

  Corresponding to these, the controller 80 determines that the temperature in the urine tank 20 is a predetermined temperature based on the temperature of the urine 24 in the urine tank 20 and the temperature of the feces 33 in the feces treatment tank 30. The energization to the first Peltier element 40 and the second Peltier element 140 is controlled so that the temperature is within the range and the temperature of the feces treatment tank 30 is also within the predetermined temperature range. With such a configuration, the temperature range of the urine 24 in the urine tank 20 and the temperature range of the feces 33 in the feces treatment tank 30 can be maintained under different conditions.

  For example, normally, only the first Peltier element 40 is driven to cool the urine in the urine tank 20 to a predetermined temperature range, and at the same time, the feces treatment tank 30 is heated to aim at energy saving. On the other hand, when fermentation of the feces 33 proceeds in the feces treatment tank 30 and the temperature in the feces treatment tank 30 becomes too high, the second Peltier element 140 is mainly driven. Thereby, the inside of the dung processing tank 30 can be prevented from being overheated while sufficiently cooling the inside of the urine tank 20. Therefore, it is preferable that the temperature adjustment of the urine 24 in the urine tank 20 and the temperature adjustment of the stool 33 in the stool processing tank 30 can be easily made compatible even if the usage state, the external environment, etc. change.

  In addition, as temperature in the feces treatment tank 30, it is preferable to maintain at -20-45 degreeC, More preferably, -5-30 degreeC.

  The second point in which the toilet apparatus 101 of the present embodiment is different from the toilet apparatus 1 is that it includes a gas discharge device (gas discharge means) 150 that suitably discharges the gas in the feces treatment tank 30 to the outside. Specifically, the gas discharge device 150 includes a communication pipe 111, a communication pipe 113, a communication pipe 117, and a fan 119.

  The communication pipe 111 communicates the feces treatment tank 30 and the urine tank 20. The communication pipe 113 communicates the urine tank 20 and the porous material container 60. Further, the communication pipe 117 communicates the porous material container 60 and the outside of the housing 5. The fan 119 is connected to the communication pipe 117 and exhausts the gas from the porous material container 60 to the outside of the housing 5 through the communication pipe 117. Therefore, the gas containing a relatively large amount of water vapor in the feces treatment tank 30 passes through the urine tank 20 and is discharged to the outside through the porous material container 60. At this time, the gas in the urine tank 20 is also discharged outside through the porous material container 60.

  Here, when the gas containing the relatively large amount of water vapor in the feces treatment tank 30 passes through the cooled urine tank 20, the water vapor in the gas is condensed, and this water vapor is liquid water and enters the urine tank 20. Collected. Therefore, since the dew point of the gas discharged to the outside is lowered, it is possible to prevent condensation from being generated by the exhaust gas when such a toilet apparatus 1 is provided indoors. Further, when the water vapor is condensed, the odorous gas component that remains in the gas is also collected together with the condensed water, so that the odor of the exhaust gas is reduced. It should be noted that the odorous gas from the feces treatment tank 30 may be generated by the decay of the feces 33 in a dead space where corners in the feces treatment tank 30 are difficult to be stirred.

  Further, the gas whose moisture has been reduced in this way further passes through the porous material container 60, and the remaining water vapor and odorous gas components are further adsorbed by the porous material such as sawdust in the porous material container 60. Therefore, the exhaust gas with a very small amount of water vapor and odorous components is discharged to the outside.

  In addition, since the gas in the urine tank 20 is also discharged through the porous material container 60 at the same time, ammonia or the like that is slightly volatilized from the urine 24 is also adsorbed by the porous material, thereby further reducing the amount of scattered ammonia. Is realized.

  Further, the gas in the feces treatment tank 30 and the gas in the urine tank 20 are drawn out from the container by the fan 119, the communication pipe 111, the communication pipe 113, and the communication pipe 117. Gas is prevented from leaking upward from the opening 15 of the toilet 10, and gas in the urine tank 20 is prevented from leaking upward from the opening 14 of the toilet 10, so that the user 2 of the toilet device 1 can It becomes difficult to be exposed to the warm and moist gas from the feces treatment tank 30 and the gas from the urine tank 20, and the toilet device 1 can be used more comfortably.

  In addition, the toilet device according to the present invention is not limited to the above-described embodiment, and various modifications can be made.

  For example, the toilet 10 is not limited to the above-described ones, and various types of toilets can be used as long as they can separate and discharge feces and urine excreted by the user 2. For example, the thing which isolate | separates feces 3 and urine 4 with a mechanical valve etc. may be sufficient. Also, a so-called Japanese-style toilet as shown in FIG. 4 may be used. The toilet 10 is used by the user 2 so as to straddle the toilet 10 in the width direction.

  In the first and second embodiments, the thermometer 27 is provided as a sensor for measuring the physical quantity in the urine tank 20, but instead of this, in the urine 24 in the urine tank 20 or in the gas phase. A sensor for measuring the ammonia concentration may be used. Even when the ammonia concentration in the urine tank 20 is measured, the cooling of the urine tank 20 by the first Peltier element 40 can be controlled so as to maintain the ammonia concentration in the urine tank 20 within a predetermined range. Therefore, the scattering of ammonia from the urine tank 20 can be finely controlled in accordance with changes in the usage state of the toilet apparatus 1. Of course, various sensors may be provided in the urine tank 20, and the controller 80 may control the first Peltier element 40 based on these measured values.

  Moreover, in 2nd embodiment, although the thermometer 57 was provided as a sensor which measures the physical quantity in the feces treatment tank 30, it replaced with this and odorous gas sensors, moisture sensors, etc., such as an ammonia gas concentration sensor, are provided. It may be done. Even when these sensors are used, heating by the first Peltier element 40 can be controlled so that various conditions in the feces treatment tank 30 are maintained within a predetermined range, and the feces 33 in the feces treatment tank 30 can be controlled under desired conditions. Processing is possible. Of course, various sensors may be provided in the feces treatment tank 30, and the controller 80 may control the first Peltier element 40 based on these measured values.

  In the second embodiment, the second Peltier element 140 is provided so as to cool the urine tank 20 without heating the feces treatment tank 30, but instead, the second Peltier element 140 is replaced with the urine tank 20. The feces treatment tank 30 may be heated without cooling (see the second Peltier element 140 in FIG. 3). In particular, although the urine tank 20 is sufficiently cooled, the temperature in the feces treatment tank 30 is It is effective when it is difficult to go up.

  In the present invention, the urine ammonia odor is reduced by controlling the temperature of the urine using a Peltier element. However, as shown in FIG. 3, the pH for adjusting the urine pH to 3-5. By providing the adjusting device 200, it is possible to further reduce the volatilization of ammonia from urine. As described above, when the urine cooling by the Peltier element 140 or the like and the urine pH adjustment by the pH adjusting device 200 are combined, the effect of suppressing ammonia odor is high.

  As a method of adjusting the urine pH to 3 to 5, it is effective to add rocks that elute inorganic acids, organic acids and minerals to the urine in the urine tank 20. Hydrochloric acid, carbonic acid, sulfuric acid and the like can be used as the inorganic acid, acetic acid, formic acid, lactic acid and the like can be used as the organic acid, and barley stone and the like can be used as the rock from which the mineral is eluted.
