FIG. 7 shows the configuration of the operation unit 60 for operating the excretion assisting apparatus. For example, as shown in FIG. 2, the operation unit 60 is provided on the upper surface of the right handle 5 and is shown in detail in FIG. That is, the operation unit 60 includes a change-over switch 61 and a display unit 62 that displays each of the “automatic”, “good night”, and “room clean” operation courses selected by the user with the change-over switch 61. 63, 64, and a cleaning switch 70 for driving the human body cleaning device 71 and a display unit 65 for displaying “tank replenishment”. The display units 62 to 65 are configured to perform respective display operations by light emission of a light emitter such as an LED.

FIG. 8 shows the control device 66. The control device 66 functions as control means for controlling the overall operation of the excretion assisting apparatus of this embodiment, and is composed of, for example, a microcomputer. The control device 66 receives a selection signal from the changeover switch 61, a moisture content detection signal from the moisture sensor 25, a temperature detection signal from the temperature sensor 26, and opens and closes the lid 7. A lid opening / closing detection signal is input from the lid switch 67 provided for detection, a cleaning signal is input from the cleaning switch 70, and the water level of the water supply tank 72 is lower than the water level gauge 75 installed at the lower limit position of the water supply tank 72. When it becomes lower than the position, a water level detection signal is input.

And the control apparatus 66 is based on those inputs and the control program memorize | stored previously, the said display parts 62-65, the heater 24, the motor 29 of the stirring body drive device 33, and the above.
A drive control signal is supplied to a drive circuit 68 for driving the fan 49 (motor 50) of the air purifier 47 and the human body cleaning device 71.

  Next, the operation of the above configuration will be described.

First, a base material 69 containing microorganisms that decompose organic substances is accommodated in the treatment tank 31 as shown in FIG. 1, so that the base material 69 and the microorganisms are accommodated inside the treatment tank 31. Yes.

In this case, the base material 69 is made of a porous material such as sawdust, wood chips or peat moss, and in particular, a material added with rice husks. The addition rate of rice husk is 30% or less, particularly about 10 to 15%. Moreover, what consists of intestinal bacteria and soil fungi of livestock (for example, pig) is used for microorganisms. In addition, the microorganisms may not be included in the base material 69 in advance, but may be input into the treatment tank 31 separately from the base material 69.

In this state, a power plug (not shown) of the excretion assisting device is plugged into a power outlet and connected to turn on the excretion assisting device. Then, the control device 66 starts operation. In this state, the user can use it.

When using, the user sits on the seat portion 3 and excretes, and the excrement falls on the base material 69 in the treatment tank 31. After excretion, the user can clean the local area with the human body cleaning device 71.

When the excretion assisting device is turned on and the control device 66 starts operating, first, the control device 66
Makes a decision to select a driving course. Here, the driving course is selected, “Automatic Course”,
Either “good night” or “room clean” operation is started (not shown).

Here, a case where “automatic course” is selected as shown in FIG. 9 will be described. First, when “automatic course” is selected, the display unit 64 is turned on (step 1), and “automatic course” is started (step 2).

In this “automatic course”, basically, the stirrer drive device 33 performs normal rotation and reverse rotation of the stirrer 34 alternately for 2 to 4 minutes, and pauses the rotation of the stirrer 34 for 30 minutes. ~ 1
The operation is intermittently performed by repeating the time pattern (see FIG. 10). In this state, the user
When the lid 7 of the chair 1 is opened, the lid switch 67 detects this, and if the stirrer 34 is rotating at this time, the rotation of the stirrer 34 is stopped. And if it sits on the seat part 3 and excretes, and the lid | cover 7 is closed after that, the lid | cover switch 67 will detect it, and rotation of the stirring body 34 will be restarted.

Thereby, the excrement and toilet paper etc. which were accommodated in the processing tank 31 are the base materials 69.
And stirred with the microorganisms, taken up and dispersed therein, and contacted with the microorganisms.

Therefore, the excrement stored in the processing tank 31 is gradually decomposed by microorganisms. In addition, by stirring, oxygen necessary for the decomposition of the excrement is supplied to the microorganism, and the water generated by the decomposition of the excrement is discharged.

Here, the agitation of the excrement, the base material 69 and the microorganisms of the present embodiment will be described in detail. First, the amount of the base material 69 accommodated in the treatment tank 31 is about 40 l, and the stirring body 34 is 1 of the total amount of the base material 69.
It is assumed that it is located in a height region of about / 3.

The first to third stirring blades 39 to 41 of the stirring body 34 are rotated in the bottom direction in the treatment tank 31 (
Since it is inclined downwardly in the direction of arrow A), the container closes the bottom (the excrement, the base material 69 and the microorganism) in the processing tank 31 by the rotation, and at the same time, the stored substance is removed from the processing tank 3.
The container extruded to the peripheral side of 1 and scooped up along the side surface is lifted along the peripheral side of the treatment tank 31.

Contained matter in the treatment tank 31 is convected from the bottom to the top and from the top to the bottom so that the lifted material falls to the center side (the rotation center side of the stirring body 34) in the treatment tank 31. Thus, a vortex is wound as indicated by an arrow C in FIG. Therefore,
The entire contents in the processing tank 31 can be efficiently stirred by the first to third stirring blades 39 to 41 disposed at the bottom of the processing tank 31.

In order to decompose the excrement with the microorganisms contained in the base material 69, it is necessary to efficiently contact the microorganisms with the excrement, and in addition, the odor that makes the input excrement invisible quickly or emits the excrement. In order to prevent the user from feeling early, it is necessary to quickly take up the excrement into the base material 69 and disperse it after the addition. On the other hand, when the base material 69 is agitated as described above, the excretion is taken up and dispersed very quickly. Experimentally, for example, in about 10 seconds, the excrement disappears and is dispersed. In addition, in this case, the stirring member 34 has a feature that it is sufficient to be positioned lower at the bottom in the treatment tank 31.

On the other hand, when the excrement is decomposed with microorganisms, the base material 69 has a moisture content of about 35 to 60 [in order to actively move the microorganisms to efficiently decompose and suppress the generation of odor.
%] Must be maintained. However, when the amount of excretion and the number of excretion are small, the base material 6
The moisture content of 9 may be less than about 35 to 60%.

In order to detect the moisture content, in the “automatic course” of the present embodiment, the moisture content in the processing tank 31 is detected by the moisture sensor 25 as shown in FIG. 9 (step S3).

When the moisture content is 35% or more (step S4), the operation mode is “normal mode” (step S5), “high humidity mode” (step S6), “medium humidity mode” (step S7). ) And “low humidity mode” (step S8).

The “high humidity mode” is set and executed when the detected moisture content in the treatment tank 31 is high (for example, when it is over 55%), and the stirrer driving device 33 is intermittently operated as described above. In addition to this, at this time, the fan 49 of the air purifier 47 is operated intermittently, for example, by repeating a pattern of operating for 30 seconds and pausing for 30 seconds. At this time, the heater 24 generates heat so that the temperature in the processing tank 31 detected by the temperature sensor 26 is about 38 [° C.] (step S6).

The “medium humidity mode” is when the detected moisture content in the processing tank 31 is medium (for example, 55
In addition to the intermittent operation of the stirrer drive device 33 as described above, in this case, the fan 49 of the air purifier 47 is For example, the heater 24 is operated intermittently by repeating a pattern of operating for 30 seconds and pausing for 60 seconds.
Is heated so that the temperature in the processing tank 31 detected by the temperature sensor 26 becomes about 31 [° C.] (step S7).

The “low humidity mode” is set and executed when the detected moisture content in the treatment tank 31 is low (for example, 45% or less and more than 35%). In addition to the intermittent operation as described above, at this time, the fan 49 of the air cleaner 47 is operated intermittently, for example, in a pattern of operating for 15 seconds and resting for 120 seconds, and the heater 24 is detected by the temperature sensor 26. Heat is generated so that the temperature in the treatment tank 31 is about 21 [° C.] (step S).
8).

After this, for example, it is determined whether or not 2 hours have elapsed since the start of the “normal mode” (
Step S9) While it is determined that the time has not passed (NO), the process returns to the step being executed in steps S6 to S8. If it is determined that two hours have passed (YES), the moisture content test is performed again (step S3), and the subsequent operations are repeated. At this time, for example, the total amount of the substrate 69 is 40 l.
When the amount of excrement is 200 cc, it is decomposed in about 12 hours.

FIG. 10 shows the contents of the operation in the “normal mode”. By the operation in the “normal mode”, the moisture content in the treatment tank 31 and the base material 6 in the treatment tank 31 are thus obtained.
The moisture content of 9 is maintained at an appropriate level of about 35 to 60 [%].

In the “normal mode”, the user holds the knob 57a of the switching mechanism 59 and moves the shutter 57 in the direction of the arrow B1, thereby opening the first intake port 55 and the second intake port 56. To close. With the operation of the fan 49 of the air purifier 47 in such a state, air outside the base portion 2 is sucked into the first space 43 from the first air inlet 55,
The air in the treatment tank 31 is discharged out of the apparatus from the exhaust port 54 as shown by an arrow D in FIG.

The exhausted air flows from the first space 43 to the second space 4 where the treatment tank 31 exists.
4, it passes through the first filter 46. At this time, if the foreign air is contained in the exhausted air, it is captured by the first filter 46.

Then, the air that has passed through the first filter 46 passes through the second filter 48 of the air purifier 47. Therefore, at this time, the base material 6 is gradually crushed by the above-described stirring and the like.
Dust generated in the processing tank 31, such as fine dust generated from 9, is contained in the exhausted air and is captured by the second filter 48.

At this time, the second filter 48 has antibacterial and deodorizing performance, and the above-described base material 69 is used.
In addition to the fine dust generated from the waste, other bacteria and odors from the excrement can be captured by the second filter 48.

As for this antibacterial and deodorizing performance, even if the first filter 46 is provided instead of the second filter 48, it is possible to catch germs and odors from the excrement in the same manner as described above. If both the filters 46 and 48 have the above performance, it is possible to catch germs and odors more than the above. Furthermore, these filters 46 and 48 may have only one of antibacterial and deodorizing performances.

Here, the operation of the human body cleaning device 71 in the above “normal mode” will be described with reference to FIG.

First, it is determined whether or not the water level in the water supply tank 72 is higher than the lower limit position x (step S).
21). When the water level is lower than the lower limit position x (NO), a water level detection signal is output from the water level gauge 75, the display section "tank replenishment" 65 is turned on (step S22), and the user is made to recognize it. When the “tank replenishment” 65 is turned on, the user opens the water charging lid 4 b and supplies water to the water supply tank 72 from the water charging port 4 a. When water is replenished and the water level detection signal from the water level meter 75 disappears, the “tank replenishment” 65 is turned off.

When the water level is higher than the lower limit position x (YES) (step S21), when the user opens the lid 7 for excretion, the lid switch 67 detects it (YES) (step S23).
). When the user presses the cleaning switch 70 of the operation unit 60 after excretion (YES) (step S24), the nozzle 79a of the human body cleaning device 71 is extended from the guide unit 84 and stops at a predetermined position (step S25). . Then, water is jetted from the jet outlet 81 of the nozzle head 80 toward the local area (step S26). After injection, the nozzle 79a is automatically housed again in the guide portion 84 (step S27).

  Here, the detailed operation of the human body cleaning apparatus will be described.

When the cleaning switch 70 is pushed (step S24), the motor 87 of the drive unit 83 is driven to rotate and the pinion 88 is rotated, whereby the rack 86 formed behind the nozzle 79a meshing with the pinion 88 is pushed forward, The nozzle 79a extends along the axis of the hollow portion 84a of the guide portion (see FIG. 6). The expanded nozzle 70 stops at a position where the nozzle 81 of the nozzle head 80 faces the user's local area. The local position is set in advance for general users.

Next, the water supplied from the water supply tank 72 is pressurized by the pump 77, and the electromagnetic valve 78 is opened in synchronization with the operation of the pump 77.

As a result, water accumulated in the water supply tank 72 is supplied to the water supply hose 74, the pump 77, and the solenoid valve 7.
8, the supply pipe 85, the flow path 82 in the nozzle, the nozzle head 80, and the jet outlet 81, and jets (refer FIG. 5, FIG. 6).

The amount of water ejected at this time is limited to a certain amount by controlling the driving time of the pump 77. For example, the amount of water per one time is set to about 180 cc.

For example, when a constant capacity pump such as a gear pump is used as the pump 77, the electromagnetic valve 78 can be omitted.

For the above normal mode, referring to FIG. 9, the moisture content detection of “automatic course” (step S
When the moisture content in the processing tank 31 detected in 5) is 35% or less (NO), the control device 66 sets and executes the “drying detection mode” (step S10).

In this “drying detection mode”, as shown in FIG. 12, the operation time is lowered by setting the suspension time of the stirrer driving device 33 longer than 30 minutes to 1 hour of the “normal mode” described above. In some cases,
The stirrer drive device 33 may not be operated at all. Further, when operating, the stirrer driving device 33 is not operated simultaneously with the operation of the fan 49 of the air purifier 47.

Further, in this case, the operation mode of the fan 49 is a pattern in which the operation is performed for 15 seconds and is paused for about 10 minutes, and the operation rate is lower than the operation rate of the fan 49 in the above-described “normal mode”.

Further, in addition to these operations, the human body cleaning device 71 is used as a water supply means, and the water content in the treatment tank 31 is set to 35% or more so that the base material 69 has an appropriate water content.

When the “dry detection mode” is selected, in addition to the operations of the agitator driving device 33 and the air purifier 47 described above, the human body cleaning device 71 operates as shown in FIG.

It is determined whether or not the water level of the water supply tank 72 is higher than the lower limit position in the same manner as the operation of the human body cleaning device 71 in the normal mode (step S31).

If the water level is high, when the washing switch 70 is pressed (step S34) with the lid 7 open (step S33), the control device 66 determines that the user has defecate and the “normal mode” Similarly, the nozzle 79a is extended (step S35), and the operation of injecting water to the local part of the user is performed (step S36).

On the other hand, when the lid 7 is closed (step S33) (NO), it is determined that the user is not seated, and the nozzle 79a is ejected without being extended (step S38). The sprayed water collides with the upper surface of the hollow portion 84a of the guide portion 84 in which the nozzle 79a is accommodated,
The bumped water flows down along the axis of the hollow portion 84a formed in an inclined manner in the guide portion 84. And the water which removed the guide part 84 falls in the processing tank 31 located in the downward direction, and supplies the base material 69 with water.

Further, when the cleaning switch 70 is not pressed with the lid open (step S34) (
Similarly, NO is also sprayed without expanding the nozzle 79a, and water is sprinkled into the treatment tank 31 (step S38).

Also, the amount of water ejected per time is set to about 180 cc in the dry detection mode as well.

Accordingly, the “drying detection mode” has a function of replenishing moisture by supplying water to the substrate 69 and keeping it moist.

As described above, according to the first embodiment of the present invention, the excrement excreted by the user sitting on the seat 3 of the chair 1 is rotationally driven by the stirring body 34 in the treatment tank 31 and stirred together with the base material 69 and the microorganisms. And
It is gradually decomposed by microorganisms.

Therefore, there is no hassle to dispose of the excrement, and according to the decomposition process of excrement by such microorganisms, there is very little odor and it can be prevented from staying indoors.

In addition, the chair 1 incorporates filters 46 and 48 as filters that capture foreign substances from the air discharged from the treatment tank 31, and a deodorant is mixed in the second filter 48 of these filters. As a result, foreign matters such as dust contained in the air discharged from the processing tank 31 can be captured by the second filter 48, and deodorizing can be performed with the deodorant mixed in the second filter 48. However, it can be made more suitable for indoor use.

On the other hand, by providing the moisture sensor 25 as a moisture content detecting means for detecting the moisture content in the treatment tank 31, the excretion assisting device can be operated according to the detected moisture content in the treatment tank 31. it can.

And by providing the human body washing | cleaning apparatus 71, the user can wash away the excretion adhering to a local part after excretion, and can use it comfortably. In addition, the amount of paper used to clean the local area is reduced, which can contribute to resource protection.

Further, as will be described in detail below, since the water can be replenished into the treatment tank 31 by providing the human body cleaning device 71, it becomes possible to keep the base material 69 at an appropriate moisture content.

In particular, when the moisture content in the treatment tank 31 detected in the conventional excretion trapping device is 35% or less, the moisture content in the treatment tank 31 is controlled by controlling the rotation of the stirrer 34 and the operating rate of the fan. However, with these alone, the base material 69 remains dry and dust and germs are likely to be generated. Furthermore, the work of microorganisms becomes dull,
Decomposition did not proceed.

FIG. 14 shows the relationship between the moisture content of the substrate 69 and the amount of dust (dust) generated.
When the moisture content of the base material 69 is 35% or less, the amount of dust generated when the base material 69 is agitated increases to exceed the current “restricted value by the Building Management Law”. That is,
When the base material 69 is dried, dust is likely to be generated. When the base material 69 is dried to a moisture content of 35% or less, the amount of dust that comes out exceeds the “restricted value by the Building Management Law”. Therefore, as described above, the operation rate of the rotation of the stirrer 34 and the operation of the fan 49 of the air purifier 47 is reduced, so that the stirring and exhaust of the base material 69 is reduced. In addition, the generation of dust can be reduced by adding a function to replenish moisture in the treatment tank 31, and the amount of dust on the base material 69 can be reliably kept within the “restricted value by the Building Management Law”. Filter clogging can be suppressed.

Water is indispensable for the survival and activity of microorganisms, but when the water content is low, the microorganisms become inactive. Therefore, when the moisture content is 35% or less, the decomposition treatment of the treatment tank 31 is rapidly delayed. Therefore, it is desirable that the moisture content in the treatment tank 31 is in the range of 35 to 65%.

Therefore, as described above, the processing tank 31 is used by the human body cleaning device 71 in the “drying detection mode”.
By spraying water inside, moisture content can be kept at 35% or more, microorganisms can be activated, and excrement can be decomposed quickly. Therefore, it is difficult to generate odors.

Furthermore, in the present embodiment, the injection amount of the human body cleaning device 71 is limited to about 180 cc per time, but the travel cleaning device has an injection amount of about 180 cc per time, so that the local portion can be sufficiently cleaned. it can. Furthermore, since the washing water is not put into the base material 69 in an amount of 40 l without restriction as in the case of a general household warm water washing toilet seat, microorganisms are active without increasing the moisture content of the base material 69 that decomposes excrement. Can be kept within the range that can be moved. In addition, the poor appearance such as the base material 69 being sticky due to the high moisture content can be eliminated, and a clean feeling in use can be obtained. Due to the high moisture content, the microorganisms are killed, and it is possible to prevent a process of replacing the base material 69 at an early stage with degradation of the degradation performance.

Moreover, the excretion act per day is usually 1 to 3 times per user, and the amount of washing water used per day can be limited to 180 to 540 cc. The “drying detection mode” normally operates about once every two days when there is little excretion. Therefore, for example, when the amount of water stored in the water supply tank 72 is about 5 l, it is sufficient to store water in the water tank for about one week, and it is not necessary to store water frequently, so that it is convenient for the user.

As described above, by providing the human body washing device 71 in the excretion assisting device, it is possible to clean the user's local area, reduce the dust that occurs in the dry state of the base material 69, and also increase the activity of microorganisms. Has the effect of making it difficult to breed. Then, by setting the amount of water ejected from the human body cleaning device 71 to a constant amount, the water content does not increase excessively, and the water in the pump 77 does not have to be changed frequently.

  Next, a second embodiment of the excretion assisting apparatus according to the present invention will be described.

FIG. 15 is a diagram showing the shape of the human body cleaning device 99 according to the second embodiment of the present invention. The same parts as those of the first embodiment are denoted by the same reference numerals, description thereof is omitted, and different points will be described below.

That is, the difference from the first embodiment is a human body cleaning device 99. In the second embodiment, the pump 77 that pressurizes water in the order of being connected to the water supply tank 72 can be opened and closed.
