Description

Method and apparatus for treating excrement

Technical Field

The present invention relates to an excrement treatment method and an apparatus thereof, which, when a bedridden or immobile user sets a toilet (suction cup) inserted between the thighs and defecates, treats the excrement and discharges the sewage stored in the excrement treatment apparatus directly to the outside from a sewage tank.

Background

Conventionally, various types of such excrement treatment apparatuses have been proposed, but in all of them, a sewage tank is taken out from an excrement main body, transported, and flowed into a flush toilet or the like.

Patent document 1 describes an apparatus in which an ozone generator, a tank unit, a foam generating tank, and a compressed air supply unit are provided as a cleaning agent generating and supplying means around a toilet bowl in order to obtain a high deodorization effect, and when an upper lid is opened, a cleaning agent as an aggregate of foams containing ozone is supplied into the toilet bowl.

The ozone generator is a device for generating ozone gas, and includes a device (ozone generator) for performing silent discharge in clean dry air or oxygen gas, a device using an O3 lamp, and the like.

The tank assembly comprises a main tank, a washing tank, a water tank, a quantitative mixing tank, a liquid A (water) tank and a liquid B (surfactant solution) tank.

The foam generating tank is provided with a shell body and a shell bottom.

The compressed air supply unit is composed of an air tank, and a compressor and a motor that are supported in the air tank by an elastic support body in a floating manner.

Disclosure of Invention

Problems to be solved by the invention

The device disclosed in patent document 1 describes that an ozone generator, a tank unit, a foam generating tank, and a compressed air supply unit are provided around a toilet bowl as a cleaning agent generating and supplying means, and when an upper lid is opened, a cleaning agent as an aggregate of foams containing ozone is supplied into the toilet bowl, thereby obtaining a high deodorization effect.

The device disclosed in patent document 2 washes the buttocks and the bowl with the nozzle after excretion, but has a problem that the emission of odor to the outside cannot be suppressed because the device merely stores excrement in a bucket provided below the toilet and covers the bucket.

The device disclosed in patent document 3 describes that the opening of the waste storage tank which constitutes the bowl portion of the waste container and the lower portion thereof is covered with a cover body having a tapered male-female fitting surface, but there is a problem that odor emission during defecation cannot be suppressed.

The device disclosed in patent document 4 describes that foam is supplied to the tub at predetermined intervals, but since excrement is directly stored in the tub, there is a problem that the foam disappears with time after defecation, and the odor is emitted.

In particular, although the water-washing type apparatus is water-saving, if the amount of 4 to 5 liters of washing water used is not small, the dirt in the toilet bowl does not flow into the tank or the tub, and the room is filled with odor. In addition, since 4 to 5 liters of cleaning water is used each time, a large-capacity container of 40 to 50 liters must be used for both the cleaning water tank and the tank for storing the waste. It is difficult to miniaturize the entire apparatus.

The invention provides an excrement treatment method and an excrement treatment device, which can directly discharge sewage stored in a sewage tank in a body of the excrement treatment device to the outside by using air pressure, thereby eliminating the problem of odor from the sewage tank.

an external discharge unit 13 for feeding and discharging the sewage stored in the sewage tank 25 under pressure; and

and an electrical control unit 14 for electrically controlling the entire apparatus with the CPU64 as a main body.

In the suction cup control part 10, as shown in fig. 8 (d), the suction cup 15 is attached to a position of a excretory organ in the crotch of the user 104 together with the diaper 100.

As shown in fig. 8 (a), (b), (c), the suction cup 15 comprises a diaper 100, an outer portion 101 and an inner portion 102.

The interior 102 includes a stool sensor 17 and a urine sensor 18 in a stool receiving portion 16, and a cleaning nozzle 20 in a urine receiving portion 105. A defecation suction tube 19 communicating with the defecation receiving section 16 is provided, and a blower tube 20, a water supply tube 21 and an electric wire 22 are provided behind the urination receiving section 105.

The diaper 100 is fitted in the gap between the inner part 102 and the outer part 101, and the central part is made as an inner waterproof paper 106, and the outer peripheral part of the inner waterproof paper 106 is made as a cushion material 108.

A method and an apparatus for treating excrement of a soft material are provided in which a defecation part fitting wall and a urination part fitting wall on the outer periphery of the inner fitting recess 107 project outward beyond the defecation receiving part 17 and the urination receiving part 105 when the inner part 102 is fitted.

An inner fitting recess 107 is formed in the outer portion 101 to hold the diaper 100 in close contact with a gap between the outer peripheral surface of the inner portion 102 and the inner periphery of the outer portion 101. Further, a hip receiving portion is attached to a front end portion of the outer portion 101.

The diaper 100, the outer portion 101 and the inner portion 102 are assembled by the following process.

In the first step, a diaper 100 for fitting to the crotch is attached to the back of an inner part 102 having a feces receiver 16, a urination receiver 105, and a feces suction tube 19 and functioning as an insertion toilet.

In the next step, the outer part 101 is adhered to the back of the diaper 100 so that the front surface of the inner part 102 is exposed, and a part of the inner waterproof paper 106 of the diaper 100 is sandwiched by the inner part 102.

In fig. 1, the suction pressure-feed control unit 11 mainly includes the sewage tank 25 and a suction motor 26.

A pipe 44 is connected to the top plate of the sewage tank 25 via a suction valve 31 that controls opening and closing, and a suction pressure feed port 30 and a sewage mill 33 are provided. A grinding blade 35 is provided at a lower end portion of a rotating shaft 34a of a grinding motor 34 constituting the sewage grinding apparatus 33, and grinds solid matter such as toilet waste or toilet paper collected at the center by inclined guide surfaces of a grinding cage 36, and discharges the solid matter together with sewage from small holes 37 to the outside of the grinding cage 36. Inside the sewage tank 25 (for example, 8 liters), a full water sensor 39 (for example, for detection of about 3 liters) and an empty sensor 38 (for example, for detection of 0.2 liters) of sewage are provided, and on the side of the floor, a pressure feed valve 32 is provided. The full water sensor 39 is attached to the center or slightly below the sewage tank 25, thereby preventing sewage from leaking out of the sewage tank 25 due to movement or inclination of the excrement treatment apparatus 9.

When the pressure-feed valve 32 is opened, the crushed waste and sewage are pressure-fed by air to be described later, passed through the check valve 27 and the backflow prevention trap 46, sent to the sewage pressure-feed pipe 45, and discharged from the external discharge unit 13 connected by the external connection joint 48. A specific example of the external discharge portion 13 will be described later.

The other end of the pipe 44 is connected to the defecation suction tube 19 at the position of the connection plate 23. The air pipe 43 is connected to the suction pressure feed port 30 on the upper surface of the sewage tank 25. The air pipe 43 is connected to one of the switching valves 27 via the mist filter 40, the odor filter 41, and the pressure sensor 42. The air blowing side a and the pressure-feeding side B of the switching valve 27 are switched by a valve motor 28, and one end of the pressure-feeding side B communicates with the outside atmosphere 29. The blower pipe 65 connected to the other of the blowing sides a of the switching valve 27 is connected to the blower pipe 20 by the coupling 23 via a cooling box 66 and a return box 67.

The return box 67 is provided with a HEPA filter (high efficiency filter) 69, a blast temperature sensor 70, and an excessive temperature rise monitoring sensor 71, and is provided with an exhaust throttle valve 68 that allows approximately 10% of the air circulating through the circulation path to escape to the outside atmosphere.

When the switching valve 27 is connected to the air supply side a, an air circulation path is formed to return to the stool suction pipe 19 via the stool suction pipe 19 of the suction cup 15, the pipe 44, the suction valve 31, the inside of the sewage tank 25, the suction pressure-feed port 30, the mist filter 40, the air pipe 43, the odor filter case 41, the pressure sensor 42, one of the air supply sides a of the switching valve 27, the suction motor 26, the other of the air supply sides a of the switching valve 27, the blast pipe 65, the cooling tank 66, the return tank 67, the blast pipe 20 of the suction cup 15, and the inside of the suction cup.

When the air in the air circulation path is sucked by the suction motor 26, the outside air is sucked from the gap between the diaper 100 and the crotch in a state of being placed between the crotch of the user 104, the odor is prevented from leaking, and the odor is removed from the air discharge throttle valve 68 by an amount corresponding to the sucked air amount and discharged to the outside air.

Since the operation cannot be stabilized when the amount of air sucked into the outside air is different depending on the extent of fastening the suction cup 15 with the diaper 100 to the crotch, the pressure sensor 42 in the air circulation path is used to monitor the attachment of the suction cup 15 with the diaper 100 to the crotch substantially constantly. The operation at this time will be described later.

Next, specific configurations of the suction valve 31 and the pressure-feed valve 32 attached to the waste water tank 25 will be described with reference to fig. 6 and 7.

The suction valve 31 (the pressure feed valve 32 is also configured in the same manner), the valve mounting plate 81 is provided with a suction/discharge hole 82, and the suction/discharge hole 82 is airtightly attached in a state of being aligned with the inner surface of the connection port of the pipe 44 of the waste water tank 25. At one end of the valve mounting plate 81, a tip end portion of a rotary shaft 88 protrudes inward, and a swing arm 84 having elasticity is swingably mounted to the rotary shaft 88. Two push adjustment screws 89 are provided on the swing arm 84 so as to be able to advance and retreat, and lower end portions of the two push adjustment screws 89 are fitted in the recess 91 of the slider 83. A ridge 86 is formed on the inner side of the suction hole 82 over the entire circumference thereof, and a guide 87 connected to the ridge 86 and having the same height is extended in the swing direction of the slider 83. The valve mounting plate 81 is curved in an arc shape on the side opposite to the rotation shaft 88, a guide groove 85 is formed inside the arc-shaped portion, and the tip end portion 84a of the swing arm 84 is fitted into the guide groove 85 to slide. A blade portion 92 is formed at an edge portion of the slider 83.

A motor shaft 95 of a motor 94 is connected to the outside of the sewage tank 25 of the rotary shaft 88 via two gears 93.

In this configuration, the swing arm 84 attached to the rotary shaft 88 has its tip end portion 84a fitted into the guide groove 85, and the slider 83 is supported by two pressing adjustment screws 89 in the middle portion. The slider 83 is adjusted by pressing an adjusting screw 89 so as to come into contact with a ridge 86 and a guide rail 87 with a constant pressure by the elasticity of the swing arm 84, and slides to control the opening and closing of the suction hole 82. At this time, the blade portion 92 of the slider 83 cuts off dirt and other solid matter, and reliably blocks the suction hole 82.

The pressure-feed valve 32 is attached to the inside of the bottom of the sewage tank 25, and is configured to be opened and closed reliably when the sewage is pressure-fed to the outside, similarly to the suction valve 31.

The opening and closing of the suction valve 31 or the pressure-feed valve 32 are reliably controlled by providing an optical sensor or the like at the position of the stopper 96 of the swing arm 84.

In the washing water control unit 12 shown in fig. 1, the washing water tank 53 has a capacity of storing about 3 liters of washing water, and is fitted to the subtank 54 having a water level sensor 55 near the bottom thereof as a usage amount of defecation and urination about 10 times a day. About 0.5 liters of washing water naturally falls from the washing water tank 53 and is supplied to the sub-tank 54 at any time. The water pump 57 is connected to the sub-tank 54 of the capacity via the filter 26, and the driving time of the water pump 57 is controlled by a timer. A manual drain 59 for draining water as required is connected to the subtank 54. The relief valve 58 is coupled to the water pump 57, and when any abnormality occurs in a supply path leading to a suction cup coupled to the water pump 57, the relief valve 58 operates to prevent a pressure increase and protect the suction cup.

The water pump 57 is connected to the water supply pipe 21 connected to the connection plate 23 via a heat insulation box 60 having a temperature fuse, a temperature sensor, and a full water sensor, a wash valve 61 for controlling the supply of wash water, and a safety box 63 having a temperature sensor and an excessive temperature rise sensor. Between the wash valve 61 and the safety tank 63, a drain air pump 62 that discharges wash water in a pipe between up to the suction cup 15 is provided.

As a first example, as shown in fig. 1, the external discharge portion 13 extends a drain pipe 50 to an external connection joint 48, is inserted into a discharge return bend 51 of a flush toilet 49, and leads to a drain pipe 52. In this example, since the existing flush toilet 49 is used, it is not necessary to newly construct it. However, since the drain pipe 50 is inserted into the toilet bowl 49, the toilet bowl 49 needs not to be closed. When the drain pipe 50 is always inserted, the lid of the toilet bowl 49 cannot be closed, and it is necessary to prevent the reverse flow of the toilet bowl 49.

As a second example, as shown in fig. 9 (a), the external discharge portion 13 is configured such that a drain pipe 50 is connected to an above-ground clearance port 110 of a drain pipe 52 by a connector 111. In this example, the above-ground clearance opening 110 having the drain pipe 52 is required, and since the shape of the above-ground clearance opening 110 varies depending on manufacturers, it is necessary to prepare dedicated connectors 111 suitable for each.

As a third example, as shown in fig. 9 (b), a backflow prevention pipe 115 is formed and connected to the rear of a return bend 114 of a waste drain pipe 113 of a washbasin 112 or the like. In this example, the miscellaneous drain pipe 113 sometimes treats drinking water, and therefore sanitary treatment is necessary.

As shown in fig. 2, the CPU64 of the electric control unit 14 is connected to various switches, sensors, lamps, and the like. Specifically, the switches of the operation panel 75 include switches for starting, setting the cleaning temperature of the incubator 60, sucking from the toilet 15, pumping from the waste water tank 25, and switching the display of various indicator lamps. The lamps of the operation panel 75 include a power supply, a cleaning water shortage, a sewage full, a suction cup connection, a remote controller connection, a two-digit numerical display, and a high/low suction pressure display lamp.

The output to the suction motor 26, the input to the pressure sensor 42, the input to the temperature sensor 70 and the excessive temperature rise sensor 71 of the return tank 67, the input to the full water sensor 39 and the empty sensor 38 of the wastewater tank 25, the output to the incubator 60, the input to the full water sensor, the temperature sensor, the excessive temperature rise sensor, the input to the water pump 57, the input to the full water sensor, the temperature sensor, the excessive temperature rise sensor when tap water is directly connected to the incubator 60, the input to the purge valve 61, the output to the drain air pump 62, the input to the temperature sensor, the excessive temperature rise sensor of the safety tank 63, the input to the stool sensor 17 and the urine sensor 18 of the suction cup 15, the input to the wireless power supply unit 24a and the power transmission substrate 24b, the output to the valve motor 28, the input to the open sensor and the close sensor, the output to the motor 28 of the suction valve 31, the input to the open sensor and the open sensor, the input to the close sensor, the output to the motor 28 of the pressure-feed valve 32, the input to the open sensor and the input to the water level sensor 55 of the water level sensor, the input to the switch 97, the input to the call input to the CPU 76, the output of the call-receiving input to the CPU64, the remote controller, and the input to the CPU 64.

The operation of the excreta management device 9 configured as described above will be described below.

When the sipping cup urine sensor 18 becomes "yes", the sipping cup small suction operation of fig. 12 to be described later is started, and +1 is added to the counter.

When the sipping cup urine sensor is "no" and the sipping cup stool sensor 17 is "yes", a sipping cup large suction operation of fig. 13 to be described later is started, and +2 is added to the counter.

In the counter, when the small suction exceeds 4 (sewage stored in the small mode (mode) four times) and the large suction exceeds 2 (sewage stored in the small mode two times), the pumping operation shown in fig. 10 is started, and the counter is reset when the counter becomes 0.

3. Small suction action of suction cup 15

FIG. 12 (a)

The check switch valve 27 is at a, and the suction motor 26 is operated.

The suction cup washing operation in fig. 12 (b) is started, the washing valve 61 is opened, the water pump 57 is operated, washing water is sent for 2 seconds to wash, and the water pump 57 is stopped. At this time, the temperature of the washing water kept in the heat-keeping tank 60 is checked by the safety tank 63.

After the timer for 2 seconds, the set values of the washing operation time of the water pump 57 for 2 seconds, the number of times of washing for 3 times, and the washing interval for 18 seconds are set in the respective registers as parameters of the small suction mode.

The suction cup cleaning operation in fig. 12 (b) is started again to clean the suction cup 15.

Let the hot water pump purge counter be +1. Then, if the suction cup stool sensor 17 does not detect a signal, the process is repeated until the washing counter reaches 3 times.

When the suction cup stool sensor 17 detects a signal, the respective registers set the respective set values of the cleaning operation time of the water pump 57 to 4 seconds, the number of times of cleaning to 5 times, and the cleaning interval to 16 seconds, as parameters of the large suction mode. In addition, when the stool sensor 17 detects a signal during the cleaning in the small suction process, the mode is shifted to the large suction mode without being shifted to the small suction mode.

When the purge counter reaches the number of purges, in order to avoid the influence of the residual pressure in the water in the pipe, the drain air pump 62 is operated for 5 seconds after the timer for 5 seconds, and the residual water and air in the pipe of the suction cup 15 are sent and discharged into the suction cup 15.

After 5 seconds of the drain operation, the suction motor 26 is stopped and the operation is terminated.

4. Large suction action of suction cup 15

Set the warm water pump purge counter to +1. Next, if the suction cup stool sensor 17 does not detect a signal, the process is repeated until the washing counter reaches 5 times.

5. Monitoring action of suction cup wearing

In the air circulation path of the suction cup 15, when air is sucked by the suction motor 26, the outside air is sucked from the gap between the diaper 100 worn in the crotch of the user 104 and the crotch to prevent odor leakage, and the odor is removed from the air discharge throttle valve 68 by an amount corresponding to the sucked air amount and discharged to the outside air.

The diaper 100 is worn with different degrees of fit between the crotch due to different degrees of skill, and the amount of air that draws outside air is also different. Since the diaper cannot be stably operated, the suction state is indicated by "suction pressure is insufficient" and "suction pressure is excessive", and whether the diaper 100 is properly worn or not can be determined by the operation described below.

FIG. 14

Wear the suction cup 15 and start the disposal of urine or feces.

At the beginning of the treatment, the LED is turned off because the suction pressure state from the diaper 100 is not high or low.

The suction pressure is processed by the pressure sensor 42 of the air circulation path.

The process proceeds to fig. 14 (b), and the suction pressure is acquired every 1 second, and a moving average value is calculated, for example, 10 times, and stored in the memory, and the process ends.

Returning to fig. 14 (a), if the pressure value is lower than the set value by "yes", the low LED is turned on, the high LED is turned off, and the pressure value is restored.

If the pressure value is lower than the set value by "no", and if the pressure value is higher than the set value by "no", both the "low LED" and the "high LED" are turned off, indicating normal.

Under normal conditions, during urination or defecation.
