The present invention relates to an automatic excretion processing device, and more particularly, to the excrement processing device that can be automatically worn by the elderly, disabled, patients, etc. that are inconvenient to move the feces and urine to automatically process the feces while the user is excreted will be.

In general, co-operation with guardians and caregivers is essential to handling the excrement of the elderly, the disabled, and the patients who are difficult to move.However, most patients refer to the urine for a long time because they feel embarrassed and are afraid of getting dirty clothes and bedding. In the process, they suffer mental and physical pain.

Therefore, in order to alleviate the mental and physical pain of the patient and to reduce the labor force of the caregiver and the caregiver, above all, the patient is freely able to see the urine, and a means to clean the urine automatically and automatically is required.

Background Art Conventionally, a large number of urine treatment devices have been developed that allow a patient or an elderly person with a sickness to live in a state of lying down and seeing the urine without the help of others.

For example, WO 2006/046532 A1 published in International Patent Publication discloses a technology having various nozzles and excretion outlets in a 'c' shaped feces processing device. According to the technique disclosed above, it is made of a structure that is completely in contact with the patient's pubic area, and detects urine with a sensor and automatically sprays washing water from various nozzles to clean the local area, and also sprays dry air to the patient The urine treatment device is configured to dry the device and pubic and anal wear.

In addition, Korean Patent No. 10-0709961 discloses a technique using a means for increasing the volume of the air tube (shrinkable member) to be in close contact with the body when worn on the human body so that it can be worn for a long time. That is, the technology described above uses air tubes that can be sized according to the size of the human body when worn on the patient's body to completely adhere to the human body to detect feces and urine and automatically separate the washing water and air from various nozzles. It is a waste treatment device configured to supply local washing and drying.

13 is an overall block diagram showing an embodiment of the automatic waste treatment apparatus according to the present invention, Figure 14 is a flow chart showing an operating state of the automatic waste treatment apparatus according to the present invention, with reference to the bar automatic waste treatment apparatus The control operation for is as follows.

First, as the excrement detection process, when the user is excreted while wearing the sanitary napkin 100, the detection unit 127 through the urine detection sensor 125 and the stool detection sensor 126 to detect the excrement Accordingly, the electrical signal is transmitted to the controller 270 of the main body 200. That is, the detector 127 continuously and periodically detects an electrical signal through a plurality of sensors, and transmits the detected signal to the controller 270 of the main body 200.

Secondly, as a waste collection and washing process, the control unit 270 receiving the electrical signal through the sensing unit 127 operates the intake and exhaust motor 250. When the intake and exhaust motor 250 is operated, the air inside the container 210 is discharged while the pressure inside the container is reduced, and the excrement contained in the accommodation space S of the sanitary napkin 100 is discharged due to the pressure drop. Forced suction is sent to the collecting container 210 of the main body 200 through 121. At this time, the control unit 270 operates the chemical pump 285 to inject a certain amount of chemical into the container 210 through the waste inflow pipe (P) to remove bacteria and remove odors.

In the process of the excrement is sucked into the container 210, the air inside the sanitary napkin 100 is also sucked into the container 210, at which time the air continuously through the air inlets 128, 144 of the sanitary napkin 100 Enter the sanitary napkin 100, and eventually the inside of the sanitary napkin 100 is to maintain a constant pressure rather than a vacuum.

The air transferred from the sump 210 to the intake and exhaust motor 250 is exhausted and transferred to the waterjet apparatus 260. At this time, the solenoid valve V is operated by the controller 270 to pump the water from the water tank 220. The water 230 is operated and the water (washing water) transferred through the ceramic line heater 240 is mixed with air while being sent to the washing water connection part 260b of the waterjet device 260, and the sanitary napkin in the water film forming part 122 at high pressure. The process of washing while spraying a mixture of water and air to the bottom surface of 100 is in progress.

In the process of collecting and washing the excrement, the amount of air discharged by the intake and exhaust motor 250 is a major factor in order to transfer the excrement having a certain weight, such as feces, to a predetermined length, the suction force of the intake and exhaust motor 250 If too small, the excrement of the sanitary napkin 100 can not be forcibly transported, whereas if the suction power is too high, the noise of the intake and exhaust motor 250 becomes severe and consumes more power than necessary, so the air volume of the intake and exhaust motor 250 is appropriately sucked. It is necessary to adjust.

Therefore, the control unit 270 controls the intake and exhaust motor 250 to adjust the air volume of the intake and exhaust motor 250 for each process by using a normal phase control (PWM) circuit, preferably in the waste collection and washing process The suction power of the intake and exhaust motor that can be optimally cleaned while reducing the volume is set to be 15m ³ / min.

Preferably, in order to prevent heat generation of the intake and exhaust motor 250, 60 to 70% of the air discharged from the intake and exhaust motor 250 is transferred to the waterjet apparatus 260, and the sanitary table 100 through the injection line 360. 30 to 40% of the air is discharged to the outside through the vent holes 250e of the intake and exhaust motor 250.

Third, the solenoid valve V is automatically changed by the controller 270 after a predetermined time as a washing process, and the water supplied from the water tank 220 is washed through the washing water line 340. The cleaning process is performed to supply the water distributor 123e, and to deliver the water to the washing water nozzles 123a, 123b, and 123c from the water distributor 123e to clean the anus and the pussy of the user.

Such feces collection and washing process and washing process is set in advance to set the number of times to repeatedly run the feces and urine. As shown in the attached case, the urine may be set to repeat this process twice, and the stool may be set to repeat seven times.

Fourthly, the drying process is performed after repeating the above washing and washing process a predetermined number of times according to the discharge discharged by the user.

Only the high temperature and high pressure air generated by the intake and exhaust motor 250 is exhausted through the exhaust pipe 250b and through the water film forming unit 122 of the sanitary napkin 100 through the discharge pipe 260c of the waterjet apparatus 260. By spraying the user's pussy and anus and the sanitary napkin 100 is dried inside. At this time, the control unit 270 adjusts the output of the intake and exhaust motor 250 by using a phase control circuit to lower the output than the output of the intake and exhaust motor 250 in the washing process, and thus the air pressure applied to the negative part and anus of the human body. Can be adjusted.

During the drying process, the pressure inside the sanitary napkin 100 is not a vacuum state due to the air injected into the sanitary napkin 100 and the air introduced by the air inlets 128 and 144 formed in the sanitary napkin 100. Since it is maintained, there is an advantage that can prevent the inconvenience caused when wearing the sanitary napkin (100).

On the other hand, the control circuit of the control unit 270 of the main body unit for controlling the functions of the components of the excreta processing apparatus of the present invention, as well as automatic operation, the user sends a signal to process the feces and urine by directly operating with a remote control washing step Can be operated, washing step and drying step.

In particular, in order to dry the sweat of the user wearing the sanitary napkin 100, for example, by allowing the intake and exhaust motor 250 to be operated at intervals of 15 minutes, for example, the drying step may be performed.
