Description

  The present invention relates to a simple toilet that decomposes manure by the action of microorganisms.

  In recent years, for example, as disclosed in Patent Document 1, wood fragments in which microorganisms that decompose human waste are propagated are deposited in a human waste tank (treatment tank), and the human waste discharged by the action of the microorganisms. A simple toilet (so-called biotoilet) that decomposes water into water and carbon dioxide is known. Such a biotoilet is configured to decompose the human waste into water and carbon dioxide gas by performing a heat treatment and a stirring treatment so that microorganisms living in the wood chips accumulated in the treatment tank are most active. Compared to a toilet equipped with a conventional urine storage tank, it does not require urine pumping work, so recently, it is also considered to be installed in a general room for the purpose of nursing as well as outdoors. Has been.

  However, when installing such a bio-toilet in a room other than a general toilet room, the user or living-in person should be aware that the odor produced by the excrement, especially that such odor fills the room. Become. In addition, the actual biotoilet does not generate odor as much as the user thinks due to the fragrance of wood by the wood fragments and the decomposition action by microorganisms, but it is better for the user to have a deodorizing function It is considered preferable.

Therefore, various biotoilets having a deodorizing function have been proposed.For example, Patent Document 2 collects odors emitted from a treatment tank in which wood strips are deposited, and passes them through a deodorizer part. A configuration for blowing (circulating) the exhausted air to the treatment tank is disclosed.
Japanese Patent No. 3271615 JP 2001-346717 A

  As described above, the conventional biotoilet having a deodorizing function is merely intended to remove the odor generated in the treatment tank, and no consideration is given to the indoor environment in which it is installed. That is, it is considered that the room where the biotoilet is installed is filled with various odors based on other than the installation of the biotoilet, such as a living odor. In addition, it is considered that it is preferable to deodorize (in the above-described known biotoilet, the indoor odor cannot be removed together). Moreover, it is thought that it is mentally preferable for the user who actually uses a toilet to be able to grasp sensuously that the odor produced especially when excreting is removed.

  The present invention has been made paying attention to the above-mentioned problems, and is a simple toilet that decomposes manure by the action of microorganisms, which can deodorize odor caused by excrement and improve the indoor environment. The purpose is to provide.

Adsorption effect (deodorization effect) is high. For this reason, in addition to the deodorizing action by the decomposition process by microorganisms, a higher deodorizing effect can be obtained, and the odor due to the urine in the treatment tank can be more effectively suppressed.

  Moreover, the simple toilet which concerns on Claim 5 uses the activated carbon carbonized at high temperature at 1200 degreeC or more for the said 1st deodorizing part or the 2nd deodorizing part, It is characterized by the above-mentioned.

  As described above, activated carbon carbonized at a high temperature of 1200 ° C. or higher has a high deodorizing effect and can exert a more negative ion effect. That is, when the user is seated on the toilet seat, it is possible to enhance the relaxation effect on the user during excretion by using such activated carbon for the second deodorant part installed in the vicinity of the toilet seat. It becomes.

  The simple toilet according to claim 6 is characterized in that a third deodorizing part made of activated carbon carbonized at a high temperature of 1200 ° C. or higher is mounted on the back surface of the lid member mounted on the toilet seat.

  By attaching such activated carbon to the back surface of the lid member, it is possible to more effectively remove the odor trapped inside, and in the treatment tank by the heating effect by far infrared rays released in large quantities It becomes easy to maintain the environment of this in the optimal state for microorganisms.

  ADVANTAGE OF THE INVENTION According to this invention, the simple toilet which decomposes | disassembles manure by the effect | action of microorganisms which makes it possible to deodorize the odor produced by excrement and to improve indoor environment comes to be obtained.

  Hereinafter, an embodiment of a simple toilet according to the present invention will be specifically described with reference to FIGS. 1 to 4. In these drawings, FIG. 1 is a side view showing an outline of the internal configuration of a simple toilet, FIG. 2 is a plan view thereof, FIG. 3 is a front view showing an outline of the internal configuration, and FIG. It is a general | schematic disassembled perspective view of the principal part.

  The simple toilet 1 according to the present embodiment is provided on a flat floor board 3 and includes a main body (pedestal) 5 on which a user sits. In the main body 5, microorganisms that decompose manure are inhabited. A treatment tank 7 in which wood strips 6 (for example, made of cedar) are deposited to a predetermined level is accommodated.

  In the treatment tank 7, in order to activate microorganisms that inhabit the wood pieces, a stirring blade 8a for stirring the wood pieces is provided. The stirring blade 8a has a rotating shaft 8b below the treatment tank 7. And is driven to rotate at a predetermined speed. A detailed description of the specific configuration of the power transmission mechanism that transmits power from the stirring motor 8 to the rotating shaft 8b is omitted.

  Air is sent to the rotary shaft 8b via a blower blower 10 installed in the main body 5 and a blower pipe 12 connected to the blower blower and extending into the treatment tank 7, and rotates. Air is supplied to the wood strip 6 through a plurality of openings 8c formed in the shaft 8b. In addition, a heater 13 as a heating means is installed on the lower surface of the treatment tank 7 so that the temperature of the treatment tank 7 is managed and controlled so as to be an optimum temperature for microorganisms living in the wood strip 6. It has become.

  In addition, about the stirring management by the stirring motor 8, the ventilation management by the ventilation blower 10, the temperature management by the heater 13 with respect to the wood strip, etc., it is controlled and managed by a control means (not shown) so that microorganisms can be most activated. (Detailed control method is omitted). In this case, at least for the drive of the agitating motor, in consideration of safety, drive control is performed when a situation in which the user is not using is detected (stopped when the user opens the toilet seat lid member for use) Control).

  On the treatment tank 7 of the main body 5, a toilet seat 15 on which a user is seated when excreted is installed. In this case, the toilet seat 15 includes a frame 15a, a seating member 15b supported to be rotatable with respect to the frame 15a, a lid member 15c, and a cylindrical protruding portion 15d formed to protrude downward with respect to the frame 15a. The protrusion 15d is fixed by being fitted into an opening 17a formed in the base member 17 installed on the upper surface of the main body 5. The base member 17 is fitted into the opening 7a of the processing tank 7.

  The floor plate 3 and the main body 5 extend from the front to the rear on both sides of the toilet seat 15 so as to allow the user to sit safely and stably. A handrail 20 (the back side functions as a backrest) 20 is provided. Further, a step 22 is provided at the front lower part of the main body 5 so that the user can put his / her foot when the user is seated.

And the simple toilet 1 comprised as mentioned above is provided with the deodorizing means for removing the indoor living odor and the odor which generate | occur | produces in a processing tank.
Hereinafter, the structure of the deodorizing means which concerns on this embodiment is demonstrated.

  The base member 17 is formed with an exhaust port 17 b that opens into the processing tank 7. An exhaust path (intake duct) 25 for guiding odor is connected to the exhaust port 17b, and a first deodorizing unit 27 and an exhaust fan 28 are installed in the exhaust path 25. That is, when the exhaust fan 28 is driven, the odor in the processing tank 7 receives a suction action along the exhaust path 25, is deodorized by the first deodorizing unit 27, and is then exhausted indoors. .

  A second deodorizing unit 30 is installed on both sides of the toilet seat 15. The second deodorizing unit 30 only needs to be configured to be able to deodorize by sucking indoor air, and is placed on the holding unit 17c formed on the base member 17 and held. The hole 17d formed in the portion 17c and the exhaust port 17b are connected to the exhaust path 25. For this reason, indoor air comes to pass through the 1st deodorizing part 27 via the 2nd deodorizing part 30 and the exhaust path 25, and it becomes possible to improve a deodorizing effect more.

  The first deodorizing unit 27 and the second deodorizing unit 30 described above are only required to be able to remove odor effectively. For example, a deodorizing material using a material having an action of adsorbing odor (for example, activated carbon). Means, a deodorizing means by generation of ozone and catalysis, a deodorizing means in which a chemical component effective for deodorizing is attached to a solid such as a ceramic or the like can be used.

In this case, if the deodorizing means is composed of activated carbon, it is preferable to use activated carbon carbonized at a high temperature (carbonized at 1200 ° C. or higher so that the specific surface area is increased). According to such activated carbon, compared with general Bincho charcoal, the carbonization rate is high (general Bincho charcoal is 80%, whereas carbonized at high temperature of 1200 ° C or higher is 91%). Has a high specific surface area of about 100 times (the surface area of general Bincho charcoal is 2 m ² / g, while carbonized at 1200 ° C. or higher is 270 m ² / g, which is about 100 times). Therefore, since a larger number of free electrons are retained, the effect of adsorbing the odorant positron (deodorization effect) is increased, and the negative ion effect (general Bincho charcoal is -1200 for -250 ions). What is carbonized at a high temperature at a temperature higher than or equal to ℃ becomes -750 ions, and more than 3 times) can be exerted more strongly. That is, since the second deodorizing unit 30 is disposed in the vicinity when the user is seated on the toilet seat 15, such a negative ion effect causes a relaxation effect on the user during excretion. It is also possible to increase.

  In the above-described configuration, excreted excreta is decomposed and disappeared by microorganisms that inhabit the wood strip 6 filled in the processing tank 7, so that there is no need to perform operations such as pumping. It is very clean and does not give off a bad odor in the installed room. In addition, the odor generated in the treatment tank (when using cedar wood for the wood strip, the scent of cedar rather than the odor due to excrement) is deodorized through the first deodorizing unit 27. The room is not filled with any odor.

  Furthermore, indoor odors (odors not related to simple toilets; life odors) are also deodorized through the second deodorization unit 30 and the air that has passed through the second deodorization unit is further reduced. Since it passes through the first deodorizing unit 27, the indoor purifying action is more effectively exhibited.

In addition, it is preferable to mix the activated carbon carbonized at the above high temperature with the wood strip 6 deposited in a processing tank. As described above, the activated carbon treated at such a high temperature has a large specific surface area and retains a larger number of free electrons, and has a deodorizing ability 3 to 10 times that of general activated carbon. In addition to the deodorizing effect by the deodorizing part, it is possible to exhibit the deodorizing function more effectively. Compared with cedar wood (surface area 30m ² / g), which is a small piece of wood, it has a large surface area, so it is also effective as a place where microorganisms live. The absolute number of microorganisms increases and the speed of manure treatment Can be greatly shortened.

  Moreover, it is preferable to attach the 3rd deodorizing part 30a by the activated carbon carbonized at high temperature at 1200 degreeC or more on the back surface of the cover member 15c with which the said toilet seat 15 is mounted | worn. Such activated carbon has a high deodorizing effect as described above, and also has a high carbonization rate compared to general Bincho charcoal, so its properties are close to ceramics, and far-infrared radiation is also high. Get higher. In particular, when the environmental temperature increases due to the temperature control of the heater 13, the amount of radiation of far infrared rays increases and the heating effect is enhanced. That is, when the temperature in the treatment tank is increased in order to increase the activity of microorganisms, secondarily, the far-infrared rays emitted from the third deodorizing part 30a installed above the wood strips cause the inside of the treatment tank to The environmental temperature rises, and it becomes easy to maintain a suitable environment for microorganisms throughout the entire treatment tank efficiently (with reduced energy loss) as a whole. Moreover, since it has the effect of warming up the inside (core) of the wood strip, it is possible to help the growth of microorganisms and increase the decomposition rate of manure.

  Of course, by attaching such a deodorizing portion made of activated carbon to the back surface of the lid member 15c, it becomes possible to more effectively remove the odor trapped inside the treatment tank.

  Although the embodiment of the present invention has been described above, the present invention can be configured and implemented as follows, for example, in addition to the above-described embodiment.

  The installation location of the second deodorizing unit 30 that sucks room air is not particularly limited, and a deodorizing may be performed by installing a suction path different from the exhaust path 25 described above. Further, the arrangement location of the first deodorizing unit 27, the indoor odor to be sucked in, the odor guide route of the processing tank, and the like can be appropriately modified according to the configuration of the main body 5 and the processing tank 7.

  Furthermore, the configuration of the stirring blade (stirring device) installed in the treatment tank, the configuration of the heating means (heater), the configuration of the blower, etc. can be modified as appropriate, and the drive control of each device is also used. It is appropriately modified in consideration of the safety of the person, the activation of microorganisms, and the like.
