As shown in Fig. 7, the buttock cleaning nozzle 104 is a nozzle for cleaning the excrement attached to the hip portion of the patient with the washing water as the spraying range. The buttock cleaning nozzle 104 has a plurality of buttock jetting holes 104 a so that the spraying direction thereof is directed to the buttocks of the patient, and a predetermined curvature corresponding to the curved surface of the buttocks in order to enable more extensive cleaning. It is excreted in the form having. The butt-cleaning jetting hole 104 a is configured to gradually increase the diameter of the jetting hole toward the center in order to maximize the jetting pressure of the washing water sprayed on the central part of the buttocks of the patient with the most feces adhering. In addition, the flow rate of the washing water injected from the buttock cleaning nozzle 104 is set to 4.68 l / min, and the average flow rate is 0.02 m / s.

The feces nozzle 105 is a treatment that causes the feces to flow from the dirt flow path 101 toward the discharge part 102 while mainly crushing the feces finely by the injection water pressure of the washing water (hereinafter, referred to as a 'stool grinding process'). Is a nozzle for performing. The feces nozzle 105 is disposed on the bottom surface side of the lower dirt passage 101 of the nozzle 104. The feces nozzle 105 has a plurality of fecal crushing injection holes 105a such that the ejection direction is directed to the bottom surface of the dirt flow path 101 and directly below the anus of the human body where feces are most likely to collect. In order to maximize the injection pressure of the washing water sprayed toward the center of the dirt flow path 101, which is the point where feces are most likely to collect as the spraying range, the stool crushing injection hole 105a gradually increases the diameter of the injection hole toward the center. Consists of. In a related configuration, the stool deposited in the center of the dirt flow path 101 is first crushed to ensure a flow path in which the washing water flows toward the discharge part 102. Therefore, the feces accumulated at the initial stage of starting the injection of the washing water from the feces nozzle 105 prevents the flow of the washing water, thereby preventing the washing water from overflowing from the dirt flow path 101. The flow rate of the washing water injected from the feces nozzle 105 is set to be 4.8 l / min, and the average flow rate is 0.013 m / s. In addition, the stool nozzle 105 communicates with a pressurized pump 600 to be described later, and sprays hot water from the hot water tank 501 as washing water of 3 L per minute and a water pressure of 1 kgf / cm 2 per minute from the stool nozzle 105. It is configured to do so.

The feces nozzle 105 is provided with a sensor cleaning hole 105b above the butt cleaning injection hole 104a above the feces crushing injection hole 105a. As shown in FIG. 4, the sensor cleaning hole 105b is configured such that its spraying direction is directed to the light receiving portion 107 of the infrared sensor described later disposed near the discharge portion 102. According to the constitution, the sensor cleaning hole 105b is sprayed with water to the light-receiving portion 107 disposed at the opposing position after the stool crushing process is completed in addition to the stool crushing process to clean the surface of the infrared sensor. It is possible to prevent malfunction.

The nozzle 202 for a bidet shown in FIG. 8 is a nozzle for washing the excreta in a human part as a main injection range, and it is narrow and long so that it can wash | clean a part regardless of a gender difference and a body shape. It has a long shape. The bidet nozzle 202 has a plurality of bidet jetting holes 202a so that the jetting direction is directed to the patient's pussy. The bidet jetting hole 202a has a smaller hole diameter and a larger number of holes than the buttock jetting hole 104a of the buttock cleaning nozzle 104 and the fecal crushing jetting hole 105a of the feces nozzle 105. It consists. With this configuration, it is possible to moderately suppress the injection pressure of the washing water while performing a wide range of washing, and it is possible to wash the human body and the particularly delicate pussy smoothly. The bidet nozzle 202 has a plurality of urine treatment injection holes 202b so as to surround the entire side portion in order to wash the urine scattered inside the toilet bowl A. The flow rate of the washing water sprayed from the bidet nozzle 202 is set to 4.68 l / min, and the average flow rate is 0.010 m / s.

As shown in Fig. 9, the anal nozzle 203 is a nozzle for cleaning the excrement attached to the anus and the anus of the patient as the spraying range, and the anal center is formed by a plurality of anal central spray holes 203a disposed at the center thereof. It has the some anal periphery injection hole 203b arrange | positioned at the both sides of the injection hole 203a. The central anal jetting hole 203a is configured such that its jetting direction is directed to the anus of the patient, and the anal peripheral jetting hole 203b is configured so that its jetting direction is directed to the periphery of the anus. The hole diameter of the anal central injection hole 203a is larger than that of the anal periphery injection hole 203b, while the diameter of the hole is substantially the same as the diameter of the hole of the feces crushing injection hole 105a and the butt-cleaning injection hole 104a. Consists of. In this configuration, it is possible to increase the injection pressure of the washing water sprayed from the anal central injection hole 203a and to wash deep into the anus of the human body. On the other hand, the injection pressure of the washing water sprayed from the anal periphery injection hole 203b can be appropriately suppressed, and the human body, among the delicate anal peripheries, can be gently washed. The flow rate of the washing water sprayed from the anal nozzle 203 is set to be 4.8 l / min, and the average flow rate is 0.019 m / s.

In addition, in order to enable more effective cleaning, an orifice structure may be adopted for the stool pulverization injection hole 105a and the anal central injection hole 203a. The orifice structure makes it possible to widen the spray range of the washing water and to clean a wide range of human parts while suppressing the amount of washing water.

In addition, the various nozzles 104, 105, 202, and 203 described above are configured to supply not only washing water but air through the various nozzle tubes 602, 603, 604, and 605 rather than the main body portion C. . That is, after washing each part of a patient with wash water, it is made to dry by blowing air. As shown in FIG. 4, when air is supplied from the various nozzles 104, 105, 202, and 203 into the toilet bowl A, the air vent 112 is used to direct the air from the toilet bowl case A to the outside air. ) Is drilled at a predetermined position of the lifting unit 200.

The structure of the various sensors 106, 107, 108, and 109 is explained in full detail. As shown in FIG. 4, the light emitting unit 106 of the infrared sensor is disposed at the end of the toilet bowl A opposite to the waste passage 101 and the discharge unit 102, and above the front edge of the discharge unit 102. At the same time, the light receiving unit 107 of the infrared sensor is disposed, and the receiver 108 of the infrared sensor is disposed adjacent to the light emitting unit 106. These light emitting unit 106, light receiving unit 107, and receiving unit 108 function as a stool detection sensor G that detects the feces in the dirt flow path 101. In the toilet bowl case (A), a urine detection sensor (H) for detecting urine is disposed at the bottom of the dirt storage space (s).

The feces detecting sensor G is provided between the light receiving unit 107, that is, the dirt flow path 101, to the light emitting unit 106 based on whether or not the infrared rays transmitted by the light emitting unit 106 are received by the opposing light receiving unit 107. To detect whether or not feces are present, the light receiving portion 107 is disposed on the upper portion of the discharge portion 102, which is hard to reach the surrounding light, in order to prevent a malfunction caused by the ambient light other than infrared rays.

Here, when the patient uses the toilet bowl case A on a cushion-high bed, the toilet bowl case A may be crushed due to being pressed by the patient's own weight, and may cause inclination in the dirt flow path 101. In such a case, the cleaning in the toilet bowl case A and the suction of the excreta are insufficient, so that the light emitting unit 106 sinks in the cleaning water remaining in the dirt flow path 101 so that infrared rays do not reach the light receiving unit 107. As a result, the stool detection sensor (G) is in the same state as when the stool is detected, the toilet bowl (A) causes a malfunction.

In order to prevent this malfunction, the stool detection sensor G is equipped with the receiving part 108 in the vicinity of the light emission part 106 for detecting the inclination of the vortex toilet case A as shown in FIG. The receiving unit 108 is disposed so as to be adjacent to each other in the light emitting unit 106 so that the infrared rays transmitted from the light emitting unit 106 to the side can be detected, but when the light emitting unit 106 and the receiving unit 108 are submerged, they are infrared rays. Can not be detected.

Therefore, the stool detection sensor G sinks in the washing water remaining in the dirt flow path 101 in the light emitting unit 106, so that both the light receiving unit 107 and the receiving unit 108 do not receive infrared rays. In A), a configuration capable of detecting that a tilt is occurring is achieved. When the feces detecting sensor G detects that the inclination has occurred in the vortex toilet case A, an error indication is displayed for the display part not shown in the main body part C, and the main body part C has all functions. Stop. In addition, when the situation where the toilet seat case A cannot arise, the stool detection may be performed only by the light emitting unit 106 and the light receiving unit 107 without providing the receiving unit 108.

In addition, as shown in FIG. 4, the urine detection sensor H is equipped with a pair of electrode pin 109 arrange | positioned so that it may neighbor each other before and after. In addition, the electrode pin 109 is connected to the main body portion C via a conductive wire (not shown), and is set so that a weak current flows to either of the electrode pins 109 from the main body portion C. . The urine detection sensor H is configured to detect a current value when the washing water or urine flows as a conductor by a weak current applied between the electrode pins 109.

Here, in general, since there is a difference in salinity between the washing water and urine, there is a difference in electrical conductivity, so that the current value detected by the urine detection sensor H becomes a different value from the washing water and urine. FIG. 10 (a) is an experimental result of measuring a current value for various types of water which can be used as washing water using a urine detection sensor (H), and FIG. 10 (b) shows randomly selected subjects (A) to (E). This is an experimental result of measuring the current value in urine. In addition, the urine sensor value is the current value converted into a voltage value using an A / D converter. For example, in FIG. 10 (b), "urine (A)" shows the result of measuring the urine of the subject (A).

As can be clearly seen from Fig. 10, urine has a high salinity compared with water, and it is confirmed that there is a large difference in the urine sensor values of both in response to the difference in salinity. Therefore, the urine detection sensor H detects the current value between the electrode pins 109 and, for example, makes it possible to reliably discriminate the washing water and urine by using a limit value of 2.0 V for the urine sensor value.

In addition, the electrode pin 109 is gold-plated on the surface to prevent corrosion, and the electrode pin 109 is configured to intersect the + and − poles of the applied voltage. By the relational structure, only one of the electrode pins 109 is oxidized and corroded, or foreign matter adheres, thereby preventing inconvenience of deterioration in detection accuracy.

The tank cover 304 has an elliptical opening (not shown) that opens and closes as described later. The tank cover 304 is connected to the waste inlet pipe 103 by the waste storage tank 300, and in connection with the opening of the tank cover 304, it also serves as a stopper of the waste storage tank 300. An elliptical hose connection portion 303 corresponding to the shape is detachably disposed. The dirt-retaining tank 300, the case of the main body part C not shown, the opening part of the tank cover 304, and the hose connection part 303 have predetermined directionality to the connection, as described above, respectively, If not connected after satisfying the predetermined directionality of these, they are not combined well. Therefore, when these are not combined satisfactorily, it is comprised so that the sealed state in the waste water storage tank 300 may not be ensured by the tank cover 304 being loosened with respect to the waste water storage tank 300, and the like.

The upper portion of the tank cover 304 is provided with a fixing metal fittings 310 for fixing the hose connecting portion 303 to the tank cover 304. Both ends of the fixing bracket 310 is freely disposed on the tank cover 304 to raise the fixing bracket 310 in a state in which the hose connecting portion 303 is connected to the tank cover 304 to raise the upper portion of the hose connecting portion 303. The tank cover 304 is configured to be fixed by being pressed.

As shown in FIG. 15, a case 307 is disposed above the hose connecting portion 303, and a pair of electrode pins 308 are fixedly supported at predetermined intervals in the case 307. The electrode pin 308 is connected to a pair of signal lines 309, which are connected to a control circuit (not shown) in the main body portion C. From this control circuit, either of the signal lines 309 can be connected. It is set to let a current flow through. The electrode pin 308 mounts the tank cover 304 to the waste water tank 300, mounts the hose connection 303 to the tank cover 304, and contacts the fixing metal fitting 310 causing the fixing metal fitting 310. It is configured to. In this state, electricity flows through the fixing metal fitting 310 between the electrode pins 308, and the tank cover 304 and the hose connecting portion 303 are detected by the control circuit in the main body portion C. ) Is detected. If the connection between the tank cover 304 and the hose connecting portion 303 is bad, and the sealed state in the waste water tank 300 is not secured, the energization described above is not detected and the main body portion C stops all functions. Then, an error display is made on a display portion of the main body portion C, not shown. Therefore, it is possible to prevent the main body portion C from malfunctioning in a state where the waste water storage tank 300 is not attached to the excrement accommodation portion D. FIG.

As shown in FIG. 13, the inner lid body 305 may be provided on the inner side of the waste water tank 300 of the tank cover 304, and the inner cap body 305 of the pair may be connected to the hose 303. When opening is separated from the tank cover 304, the opening of the tank cover 304 is configured to be automatically closed from the inside of the waste water storage tank 300. That is, as shown in FIG. 13, the inner cap body 305 is given a pushing force in the closing direction by the spring 306, and in the state where the hose connecting part 303 is removed, the inner cap body 305 is a spring ( The opening of the tank cover 304 is closed from the inside of the waste water tank 300 by the pushing force of 306. On the other hand, as shown in Fig. 14, the inner lid 305 is opened in the lower vertical state in a state where the hose connecting portion 303 is inserted into the tank cover 304 and connected. According to the related structure, when removing the dirt storage tank 300 from the main-body part C and discarding the dirt inside, even if the hose connection part 303 is removed from the dirt storage tank 300, the opening part of the tank cover 304 may be removed. Since it is automatically closed by the inner lid 305, the odor or dirt itself in the waste storage tank 300 does not leak to the outside, it is possible to safely transport the waste water tank 300. After moving the waste water storage tank 300 to a predetermined place, the tank cover 304 is removed so that the waste water is discarded from the outlet of the upper portion of the waste water storage tank 300.

In addition, as shown in FIG. 15, the inlet pipe 401a is connected to the hose connection part 303 so that the dirt inflow pipe 103 may be mutually adjacent. As shown in FIG. 1, the waste accommodation tank 300 is connected to the apparatus control part F via the suction pipe 401a. The inside of the waste accommodation tank 300 is the device control unit (F) to be described later through the suction pipe 401a by the operation of the suction pump 400, the air is sucked in and a negative pressure is formed, the dirt inflow pipe 103 The dirt can be sucked from the toilet bowl case (A).

As shown in FIG. 1, the washing water supply unit E includes a hot water tank 500 for supplying raw water as washing water and a hot water tank 501 for heating the washing water supplied in the toilet bowl A to a predetermined temperature; The solenoid valve 503 which controls the water supply from the raw water tank 500 to the hot water tank 501 is provided. The hot water tank 501 is a tubular heater 502 for heating the raw water supplied through the solenoid valve 503 from the raw water tank 500, a water level sensor 505 for detecting the water level, and a temperature sensor for detecting the water temperature 506 equipped.

When the washing water supply unit E detects that the water level in the hot water tank 501 requires water supply by the water level sensor 505, the solenoid valve 503 is opened to the hot water tank 501 from the raw water tank 500. When a predetermined amount of raw water is supplied and the water level sensor 505 detects that the hot water tank 501 is filled with raw water and reaches a predetermined level, the solenoid valve 503 is closed based on the detection signal of the water level sensor 505. Shut off the raw water supply.

The washing water supply unit E detects the temperature of the raw water in the hot water tank 501 with the temperature sensor 506, and supplies the related raw water to the tube heater 502 so that the patient is maintained at the set temperature through a temperature control circuit (not shown). ) And make hot water. When the washing process of sending hot water in the hot water tank 501 to the toilet bowl A with washing water is performed, the washing water at a proper temperature is always supplied to the patient, so that the patient can obtain a good use state. The outlet disposed at the bottom side of the hot water tank 501 is connected to the apparatus control unit F through the water supply pipe 504a, and the washing water heated in the hot water tank 501 through the water supply pipe 504a is connected to the device control unit ( F) is supplied. In addition, instead of the solenoid valve 503, a float valve or the like may be used to adjust the raw water supply from the raw water tank 500 to the hot water tank 501 by mechanical operation.

As described above, the apparatus control unit F is connected via the excrement accommodation unit D and the intake pipe 401a, and is also connected through the washing water supply unit E and the water supply pipe 504a. In the apparatus control unit F, the intake pipe 401a includes an intake valve 409 as a valve, a vacuum tank 408 as a pressure reducing unit, a suction pipe 401b, a primary odor removal filter 407a, and a pressure switch 413. The intake pipe 401c is connected to the intake port 402 of the intake pump 400 via the intake pipe 401c, the NO port of the solenoid valve 6, the COM port of the solenoid valve 6, and the intake pipe 401d. In addition, the exhaust port 405 of the suction pump 400 is connected to the COM port of the solenoid valve 5, and the NO port of the solenoid valve 5 is connected to the secondary odor removal filter 407b through the air discharge pipe 414. .

Looking at the cleaning process, after detecting the dirt by the various sensors (G, H), to perform the process of removing the odor due to dirt in the toilet bowl case (A), specifically, the waste storage tank 300 The air is sucked in by the operation of the suction pump 400 and the negative pressure is maintained, so that air flows from the inside of the toilet bowl A toward the dirt inflow pipe 103, the dirt storage tank 300, and the suction pump 400. This air is the air accompanying the odor of the dirt in the toilet bowl (A), but the odor is removed by the primary odor removal filter 407a in preparation for the dirt receiving tank 300 and the suction pump 400 do. As the odor is removed by the primary odor removal filter 407a and the corrosive gas is also removed, the corrosion of the suction pump 400 can be prevented.

In addition, the air flowing from the exhaust port 405 of the suction pump 400 toward the secondary odor removing filter 407b is discharged to the outside after the odor is further removed by the secondary odor removing filter 407b. When the air is discharged to the outside, the secondary odor removal filter 407b can be completely prevented from leaking outside of the odor, and the odor removal effect is longer than when the primary odor removal filter 407a is provided. You can keep on.

On the other hand, the water supply pipe 504a includes a filter 507, a water supply pipe 504b, a pressurized pump 600, a water supply pipe 504c, a T-shaped pipe 412, a nozzle pipe 601, various solenoid valves 1, 2, 3, 4 and various nozzle tubes 602, 603, 604, and 605 are connected to various nozzles 104, 105, 202, and 203 in the toilet bowl A. That is, by pressing the washing water supplied from the washing water supply unit E by the pressure pump 600, the washing water can be sprayed from the various nozzles 104, 105, 202, and 203 into the toilet bowl A. It becomes a composition. The filter 507 is for removing the foreign matter mixed in the washing water so that foreign matter does not flow into the pressure pump 600.

In the cleaning step, the stool pulverizing process described above is executed after the step of removing odor due to dirt in the toilet bowl A. Specifically, the suction pump 400 is operated to open the solenoid valve 4 while maintaining the suction in the toilet bowl A, and the pressurized pump 600 is operated to inject the washing water by the feces nozzle 105. Fecal grinding is performed. The feces crushed by the feces crushing process are pushed toward the discharge part 102 together with the washing water, and a part thereof is sucked and accommodated in the waste water storage tank 300 through the dirt inflow pipe 103.

However, the suction force of the suction pump 400 alone makes it difficult to completely suck and hold the dirt in the toilet bowl A in the dirt storage tank 300. In this embodiment, the dirt pumping tank 400 is used as the suction pump 400. By placing a vacuum tank 408 for increasing the suction force of the suction pump 400 and forming a vacuum state in the vacuum tank 408 between the 300 and the vacuum tank 408 to generate a stronger negative pressure dirt in the toilet bowl (A) Achieves a configuration that can efficiently suck.

Specifically, by closing the intake valve 409 in the state in which the suction pump 400 is operated, the suction of the dirt from the toilet bowl A to the waste water storage tank 300 is stopped and the suction of the suction pump 400 is continued. To form a vacuum in the vacuum tank 408. In the meantime, the stool finely crushed by the stool crushing process in the toilet bowl A is pushed into the dirt storage space s by the water pressure of the washing water, but since the intake valve 409 is closed, the discharge part 102 ) Is not sucked into the waste inflow pipe (103). Therefore, the flow of the washing water including the stool to the dirt storage space (s) is blocked, causing a vortex flow such that the washing water including the stool turns up and down (hereinafter, referred to as 'vortex phenomenon'). Due to the vortex phenomenon, the stool is further finely crushed and sufficiently mixed with the washing water, and at the same time, in the vortex bowl A, particularly near the discharge part 102 where dirt is easily attached.

Thereafter, the internal pressure of the vacuum tank 408 is detected by the pressure switch 413 disposed between the vacuum tank 408 with the suction pump 400, and at the moment when the internal pressure reaches the maximum vacuum pressure, the intake air Open the valve (409). At this moment, due to the maximum vacuum pressure formed in the vacuum tank 408, the stool sufficiently mixed with the washing water due to the vortex phenomenon is sucked into the waste water tank 300 from the discharge part 102 via the waste water inlet tube 103 at once. Will be accepted. In addition, since moisture accumulates in the vacuum tank 408 due to prolonged use, a stopper (not shown) is disposed in the lower part of the vacuum tank 408 so that the drainage in the vacuum tank 408 can be drained by removing the stopper. I am doing it.

As described above, the excrement automatic washing machine K is configured to inject air from various nozzles 104, 105, 202, and 203 to dry the human body after completion of the washing process. Specifically, the exhaust port 405 of the suction pump 400 is connected to the COM port of the solenoid valve 5, the NC port of the solenoid valve 5 is the air supply pipe 410b, check valve 411, air supply pipe 410c, T-shaped Through the pipe 412, the nozzle pipe 601, various solenoid valves 1, 2, 3, 4, various nozzle pipes 602, 603, 604, 605, various nozzles 104, 105, 202 and 203, respectively.

On the other hand, the inlet port 402 side of the suction pump 400 may be provided with an external air supply filter 404, the external air supply filter 404 via the external air supply pipe 415 to the NC port of the solenoid valve 6 The COM port of the solenoid valve 6 is connected to the inlet port 402.

For the drying process, air is drawn from the external air supply filter 404 by operating the suction pump 400 with the NC ports and solenoid valves 411 of the solenoid valves 2 and 3 and the solenoid valves 5 and 6 open. The filtered air is delivered as dry air into the toilet bowl case (A). Therefore, the air received from the external air supply filter 404 can be discharged from the buttock cleaning nozzle 104 and the anal nozzle 203 as dry air and dried in the human body and the toilet bowl A. . Air delivered in the toilet bowl case (A) is exhausted from the ventilator 112 to the outside of the toilet bowl case (A). In addition, since the check valve 411 is closed at the washing step, the washing water does not flow back to the suction pump 400.

In addition, with respect to the apparatus control unit F, the solenoid valves 1, 2, 3, and 4 are united into one unit to form a solenoid valve unit 606 which forms a pipe at one inlet and four outlets. The solenoid valve unit 606 is configured to be selectively opened and closed in sequence via a control circuit not shown in the four outlets. According to the related configuration, the pipe configuration can be simplified, the number of parts can be reduced, and the assemblability can be improved.

In addition, the solenoid valves 5 and 6, the external air supply filter 404, the primary odor removal filter 407a, the secondary odor removal filter 407b, and the pressure switch 413 are united into one unit to provide a filter assembly 607. It consists. According to the configuration concerned, the formation of the pipe line can be simplified, the number of parts can be reduced, and the assemblability can be improved, and the replacement of various filters 404, 407a, and 407b can be facilitated.

The embodiment of the present invention is configured as described above and describes the flow of procedures and functions in the case of actually using.

The feces automatic washing machine (K) discriminates feces and urine by the detection of various sensors (G and H), and performs a manual defecation mode to automatically perform each cleaning process and a manual defecation performed when a patient's operation instruction is given. It has a processing mode.

FIG. 18 is a flow chart showing a processing procedure of the excreta automatic washing machine K in the automatic defecation processing mode. As shown in Fig. 18, the excrement automatic washing machine K checks whether urine is present in the dirt flow path 101 based on the detection value of the urine detection sensor H when the main body power is turned on by an operation of a power switch (not shown). It is judged whether or not (step Sa1).

When urine does not exist as a result of this determination (step Sa1: NO), the excrement automatic washing machine K judges whether feces exist in the dirt flow path 101 based on the detection value of the feces detection sensor G ( Step Sa2). If the feces do not exist as a result of this determination (step Sa2: NO), the excreta automatic washing machine K returns the processing sequence to step Sa1 again to determine whether urine exists. On the other hand, when feces are present (step Sa2: YES), that is, when only the feces are present in the dirt flow path 101, the excreta automatic washing machine K performs the feces washing process (step Sa4).

In addition, when urine exists in step Sa1 (step Sa1: YES), the excreta automatic washing machine K determines whether feces exist in the dirt flow path 101 (step Sa3). As a result of this determination, when feces are present (step Sa3: YES), that is, when urine and feces are present in the dirt flow path 101, the excreta automatic washing machine K executes a fecal washing process for treating feces (step). Sa4).

On the other hand, the excreta automatic washing machine K carries out a urine washing step of processing urine when there is no feces (step Sa3: NO), that is, when only urine is present in the dirt flow path 101 (step Sa5). .

After completion of the feces washing step (step Sa4) or the urine washing step (step Sa5), the excreta automatic washing machine K executes a drying step for drying the human body and the toilet bowl case A (step Sa6).

As shown in FIG. 19, the waste automatic washing machine K first opens the intake valve 409 (step Sb1), and starts the intake pump 400 (step Sb2). As a result, a part of the odor due to the stool or the stool due to the stool inside the toilet bowl A is attracted to the waste storage tank 300. At the same time, air containing the odor in the toilet bowl (A) flows toward the waste inflow pipe (103), the waste water storage tank (300), the suction pump (400), and the primary odor removal filter (407a) in front of the intake port (402) and The odor is removed through the secondary odor removal filter 407b behind the exhaust port 405 and then released to the outside.

Subsequently, after opening the solenoid valve 4 (step Sb3), the pressure pump 600 is operated only for a predetermined time (step Sb4). As a result, hot water in the hot water tank 501 is delivered to the feces nozzle tube 605 and sprayed from the feces nozzle 105 as washing water to perform fecal crushing. The stool, which is crushed by the stool grinding process and pushed in the dirt flow path 101, is sufficiently mixed with the washing water by the vortex phenomenon in the dirt storage space s (hereinafter referred to as 'mixing operation by the vortex phenomenon').

Next, the excrement automatic washing machine K closes the intake valve 409 to start the vacuum formation in order to bring the inside of the vacuum tank 408 into a vacuum state (step Sb5). After waiting for the detected value of the internal pressure based on the pressure switch 413 to reach the maximum vacuum pressure (for example, 600 mmHg) (step Sb6: YES), the excrement automatic washing machine K is the pressure switch 413. The pressure pump 600 is operated (step Sb7) and the intake valve 409 is opened (step Sb8) via a control device (not shown) based on the detection signal from the above. At this moment, the feces after the mixing operation due to the vortex due to the maximum vacuum pressure formed in the vacuum tank 408 is sucked into the waste storage tank 300 at once through the waste inlet pipe 103 from the discharge unit 102 ( Hereafter, referred to as "vacuum suction operation").

The excrement automatic washing machine K stops the pressure pump 600 (step Sb9), and again determines whether there is any residue in the dirt flow path 101 based on the detected value of the feces detection sensor G (step). Sb10). As a result of this determination, if a residual is present (step Sb10: YES), the waste automatic washing machine K returns the processing procedure to step Sb5 so that the mixing operation and the vacuum suction operation by the vortex phenomenon can be repeated again. And the excrement automatic washing machine (K) repeats the mixing operation and the vacuum suction operation by the vortex phenomenon until the feces detection sensor (G) is no longer detect the feces.

Next, when no residue is detected in the dirt flow path 101 (step Sb10: NO), the excrement automatic cleaner K closes the solenoid valve 4 (step Sb11), and then opens the solenoid valve 3 (step Sb12). ), The pressure pump 600 is operated only for a predetermined time (step Sb13). As a result, hot water is sent from the hot water tank 501 to the buttock cleaning nozzle tube 604 and sprayed from the buttock cleaning nozzle 104 as washing water to clean the feces adhering to the hips of the patient (hereinafter referred to as 'buttock'). Cleaning operation ').

Next, the excrement automatic washing machine K closes the solenoid valve 3 (step Sb14), then opens the solenoid valve 2 (step Sb15), and operates the pressure pump 600 only for a predetermined time (step Sb16). As a result, hot water is sent from the hot water tank 501 to the anal nozzle tube 603, sprayed into the washing water from the anal nozzle 203, and the feces adhering near the anus of the patient is cleaned (hereinafter referred to as "analyst" Cleaning operation '). In addition, the excrement automatic washing machine K repeats the washing operation of the buttocks and the washing operation of the anus until the number of washing times reaches three times (step Sb18: YES). This makes it possible to perform a complete washing of the patient's hips and anus.

Next, when the number of times of washing reaches three times (step Sb18: NO), the excrement automatic washing machine K opens the solenoid valve 1 (step Sb19), and operates the pressure pump 600 only for a predetermined time (step Sb20). . As a result, hot water is fed from the hot water tank 501 to the bidet nozzle tube 602 and sprayed from the bidet nozzle 202 as washing water to clean the feces adhering to the patient's pubic area (hereinafter referred to as' Cleaning operation ').

Next, the excrement automatic washing machine K closes solenoid valve 1 (step Sb21), stops the suction pump 400 (step Sb22), and then various solenoid valves 1, 2, 3, 4, solenoid valve 5, The NC port and check valve 411 of 6 are opened (step Sb23), and the suction pump 400 is operated only for a predetermined time (step Sb24). Thereby, before the drying process (step Sa6) mentioned later advances, the suction pump 400 is operated, and the nozzle tube 602 for a bidet, the nozzle tube 603 for anus, the nozzle tube 604 for a cock, the stool nozzle for feces Air contained in the water from the external air supply filter 404 is blown into each nozzle pipe of the pipe 605 to remove water (hereinafter referred to as water removal operation in the nozzle pipe).

Then, the excrement automatic washing machine K closes the NC ports and check valves 411 of the various solenoid valves 1, 2, 3, 4, solenoid valves 5 and 6 (step Sb25), and terminates the feces cleaning process.

20 is a flow chart showing a processing procedure of a urine washing step. As shown in Fig. 20, the slurry automatic washing machine K first opens the intake valve 409 (step Sc1), starts the suction pump 400 (step Sc2), and then opens the solenoid valves 1 and 3 (step Sc3). The pressurized pump 600 is operated for a predetermined time only (step Sc4). As a result, urine is sucked into the dirt storage tank 300, and the washing operation of the buttocks and the washing operation of the bidet are performed.

Next, the excrement automatic cleaner K closes the solenoid valves 1 and 3 (step Sc5), opens the solenoid valve 4 (step Sc6), and then closes the intake valve 409 (step Sc7). 400 is started (step Sc8). This starts vacuum formation in the vacuum tank 408.

Then, after the predetermined time passes, the excrement automatic washing machine (K) operates the pressure pump (600), the feces through the stool nozzle tube 605 for the hot water received from the hot water tank 501 in the raw water tank (500) It sprays with the washing water from the nozzle 105, and pushes urine toward the dirt flow path 101 (step Sc9). Then, the intake valve 409 is opened almost simultaneously (step Sc10). At this moment, urine is sucked into the waste storage tank 300 at once by the maximum vacuum pressure formed in the vacuum tank 408 through the waste inlet pipe 103 from the discharge portion 102.

After that, the slurry automatic washing machine K stops the pressure pump 600 (step Sc11), then stops the suction pump 400 (step Sc12), closes the solenoid valve 4 (step Sc13), After the valve 409 is closed (step Sc14), the urine washing step is completed.

In addition, the excrement automatic washing machine (K) is sucked into the waste storage tank 300 through the first odor removal filter (407a) and the second odor removal filter (407b) for the stool cleaning process and the urine washing process described above. The odor generated from the dirt is prevented from being discharged out of the suction pump 400 as much as possible.
