Depending on the condition, a fluid such as warm water (hereinafter referred to as “cleaning water”) is used as a site to be cleaned in order to clean the anus or genital area (hereinafter referred to as “cleaning treatment site”) of the care recipient (user) 2. A spherical injection nozzle 50 that injects the liquid is provided.

As shown in FIG. 10, the injection nozzle 50 includes three water channels 50 a to 50 c for injecting cleaning water therein, and an injection direction adjusting mechanism 51 that adjusts the injection direction of the injection nozzle 50.
The three water channels 50a to 50c are configured such that warm water as washing water is supplied from the excrement disposal apparatus 300 via the composite pipe 700, and excrement by the urine sensor 23-1 and the feces sensor 23-2. In accordance with the detection result, the control device 400 adjusts the strength of jetting of the washing water, and as shown in FIGS. 12 (a), 12 (b) and 13 (a), (b), the jetting direction adjusting mechanism. 51 (FIGS. 13 (a) and (b)) is operated to appropriately clean the jet direction of the cleaning water in the direction of the cleaning target portion of the user 2 so that the cleaning target portion of the user 2 is efficiently cleaned. It has become.

  Fig.12 (a) is a front view of an injection nozzle, FIG.12 (b) is the side view which showed the movement of the up-down direction of the injection nozzle shown to Fig.12 (a). In FIG. 12B, the position indicated by the solid line is the home position, and the position indicated by the two-dot chain line indicates the top dead center and the bottom dead center, respectively.

  FIG. 13A is another schematic explanatory diagram for explaining the injection direction adjusting mechanism of the injection nozzle, and FIG. 13B shows the vertical movement of the injection nozzle shown in FIG. It is the side view shown. In FIG. 13B, the position indicated by the solid line is the home position, and the position indicated by the two-dot chain line indicates the top dead center and the bottom dead center, respectively.

  The injection nozzle 50 shown in FIG. 13A is supported by the diaper cup 10 with a flexible support member (for example, silicone rubber) and has pins on the side surfaces, and the pins have long holes at both ends. The arm 53 is inserted into one of the long holes (left side in the figure). The other hole (right side in this case) of the arm 53 is inserted with a pin of a cam 54 that can be rotated by a motor (not shown). The arm 53 is swingably supported by a fulcrum 52.

  In the injection nozzle 50, when the cam 54 rotates in one direction (for example, clockwise), the pin position of the cam 54 moves downward, and the right end of the arm 53 tilts downward to the right. When the arm 53 rotates, the left end of the arm 53 tilts upward to the left by the lever principle. Although the injection nozzle 50 is going to rise by the upwardly inclined inclination of the arm 53, since the injection nozzle 50 is supported by the support member, it finely moves so that the injection direction of the purified water is directed upward.

On the other hand, when the cam 54 rotates in the reverse direction (in this case, counterclockwise), the pin position of the cam 54 moves upward, and the right end of the arm 53 is inclined upward. When the arm 53 rotates, the left end of the arm 53 inclines to the lower left by the lever principle. The spray nozzle 50 is about to descend due to the downward sloping inclination of the arm 53. However, since the spray nozzle 50 is supported by the support member, it finely moves so that the clean water spray direction is directed downward.
As a result, as shown in FIG. 13B, when the injection nozzle 50 is located at the home position (solid line), the injection direction is horizontal, and the cam 54 turns upward or downward as the cam 54 rotates. Can be done (two-dot chain line).

In this embodiment, the shape of the injection nozzle 50 is such that the injection surface is formed in a spherical shape, but the shape of the injection nozzle according to the present invention is not limited to this, and various shapes depending on the object and purpose. Can be adopted as appropriate.
Moreover, in this embodiment, although the injection nozzle 50 has the three water channels 50a-50b, the number of the water channels of the injection nozzle by this invention is not limited to this, According to object and the objective, it is one. A water channel may be sufficient and it may be constituted by two or more arbitrary numbers of water channels.

Here, the injection direction adjusting mechanism 51 of the injection nozzle 50 will be described with reference to FIGS. 12 (a) and 12 (b) and FIGS. 13 (a) and 13 (b).
The urine sensor 23-1 and the feces sensor 23-2 detect the type of excrement of the user 2, and determine the site to be cleaned of the user 2 based on the detection results of the urine sensor 23-1 and the feces sensor 23-2. Then, the injection nozzle 50 is moved to the position most suitable for cleaning the determined site to be cleaned using the injection direction adjusting mechanism 51 shown in FIGS.

  In the present embodiment, the injection direction adjusting mechanism 51 shown in FIGS. 13A and 13B selects whether the user 2 is male or female, and injects according to the type of excrement. The injection direction of the nozzle 50 is configured to be set to a preset injection direction for men or women.

  However, since the accurate injection direction may slightly deviate from the preset injection direction due to individual differences of the user 2, the injection direction can be finely adjusted manually or using a position sensor or the like according to the user. It is configured as follows. The injection direction adjustment mechanism 51 shown in FIGS. 13A and 13B performs adjustment when a caregiver such as a nurse, a helper, or a family wears the user wearing device 200 on the user 2 for the first time. And can be adjusted as needed even after installation.

Next, the cleaning timing will be described with reference to the operation flowcharts of FIGS.
FIG. 14 is a flowchart for explaining the timing of cleaning by the automatic excretion processing apparatus shown in FIG.
First, the case where the excreta is urine will be described with reference to the operation flow chart of FIG.
When the cared person (user) 2 urinates, the urine sensor 23-1 is turned on (ON) when the urine sensor 23-1 detects urine (step S101), and the control device 400 drives the electromagnetic pump 122 (step S102). While the cleaning water is flowing through the diaper cup 10 for several seconds, the control device 400 operates the injection direction adjusting mechanism 51 according to the position of the portion to be cleaned of the user 2 to bring the injection nozzle 50 to the optimal position. Then, the blower 101 is driven while the electromagnetic pump 122 is driven, and hot water (intermittent water flow) mixed with air is supplied to the spray nozzle 50 through the water purification channel 131, the water purification channel 704, and the water purification channel 303. (Step S <b> 104) The intermittent water flow is sprayed from the spray nozzle 50 toward the cleaning target portion of the user 2 for cleaning.

Since there is an air / water mixing unit 201 for pulverizing and washing the excrement with an intermittent water flow obtained by mixing hot air for drying and washing water, the excrement is discharged from the nozzle 50 in the diaper cup 10. Since a shock is applied to a certain urine by alternately spraying water and air many times instantaneously, contamination by the user's urine in the diaper cup can be sufficiently washed (step S105). ).
The excrement processing apparatus 300 sucks the urine excreted in the diaper cup 10 from the excrement suction port 21 together with the cleaning water (sewage) that has cleaned the site to be cleaned (step S106). It discharges | emits to the waste tank 126 provided in the inside (step S107).

  After the urine from the user 2 is excreted, the control device 400 moves the position of the injection nozzle 50 to the original location (step S108), and hot water is intermittently supplied from the user wearing device 200 to the diaper cup 10 for a certain period of time. The inside of the diaper cup 10 is washed (step S109), and the sewage after washing in the diaper cup 10 is sucked from the excrement suction port 21 (step S110), and the filth tank 126 provided inside the excrement disposal apparatus 300 is used. The sewage is discharged (step S111). The control device 400 stops the electromagnetic pump 122, blows warm air from the blower 101 into the user wearing device 200, and dries the portion to be cleaned of the user 2 and the inside of the diaper cup 10 (step S112). The air used for drying is sucked from the excrement suction port 21 (step S113), and the bad odor of the air is filtered by the filter element 105 provided in the excrement disposal apparatus 300, and the blower 101, the filth tank 126, and the diaper cup When the drying process is completed, the blower 101 is turned off by the control device 400 (step S115), and the urine process is terminated.

Next, the case where the excrement is feces will be described with reference to the operation flow diagram of FIG.
FIG. 15 is a further flowchart for explaining the timing of cleaning by the automatic excretion processing apparatus shown in FIG.
When the cared person (user) 2 defecates, the stool sensor 23-2 detects stool to turn on (ON) (step S201), and the control device 400 drives the electromagnetic pump 122 (step S202). While the cleaning water is flowing through the diaper cup 10 for several seconds, the control device 400 operates the injection direction adjusting mechanism 51 according to the position of the portion to be cleaned of the user 2 to bring the injection nozzle 50 to the optimal position. Then, the blower 101 is driven while the electromagnetic pump 122 is driven, and hot water (intermittent water flow) mixed with air is supplied to the spray nozzle 50 through the water purification path 131, the water purification path 704, and the water purification path 303. (Step S204), the intermittent water flow is sprayed from the spray nozzle 50 toward the cleaning target portion of the user 2 for cleaning.

Since there is an air / water mixing unit 201 for pulverizing and washing the excrement with an intermittent water flow obtained by mixing hot air for drying and washing water, the excrement is discharged from the nozzle 50 in the diaper cup 10. Since a shock is applied to a certain feces by alternately spraying water and air a number of times alternately, contamination by a user's stool in the diaper cup can be sufficiently washed (step S205). ).
The excrement disposal apparatus 300 sucks the feces excreted in the diaper cup 10 from the excrement suction port 21 together with the washing water (sewage) for washing the site to be washed (step S206). It discharges to the filth tank 126 provided inside (step S207).

  After the excretion of the stool by the user 2 is finished, the control device 400 moves the position of the injection nozzle 50 to the original location (step S208), and supplies hot water from the user wearing device 200 to the diaper cup 10 intermittently for a certain period of time. Then, the inside of the diaper cup 10 is washed (step S209), the sewage after washing in the diaper cup 10 is sucked from the excrement suction port 21 (step S210), and the filth tank 126 provided inside the excrement disposal apparatus 300. The sewage is discharged (step S211). The control device 400 stops the electromagnetic pump 122 and blows warm air from the blower 101 into the user wearing device 200 to dry the portion to be cleaned of the user 2 and the inside of the diaper cup 10 (step S212). The air used for drying is sucked from the excrement suction port 21 (step S213), and the bad odor of the air is filtered by the filter element 105 provided in the excrement disposal apparatus 300, so that the blower 101, the filth tank 126, and the diaper cup 10 is circulated (step S214). When the drying process is completed, the blower 101 is turned off by the control device 400 (step S215), and the stool process is terminated.

Here, in the water purification channel 704 of the composite pipe 700, after washing the portion to be cleaned of the user 2 by the injection nozzle 50, the remaining water of the cleaning water (warm water) stays. Decreases to room temperature over time.
Washing with wash water having a lowered temperature gives the user 2 an uncomfortable feeling.

  Therefore, the cleaning water remaining in the water purification channel 704 (hereinafter referred to as “residual cleaning water”) is used as the cleaning water for the diaper cup 10. That is, by letting the residual cleaning water flow from the spray nozzle 50 to the diaper cup 10 for a few seconds at a low pressure, (a) cleaning water having a preset temperature is always obtained. The discomfort caused by the difference can be alleviated, and (b) since the washing water flows in the diaper cup 10 in advance, the inner surface in the diaper cup 10 can be moistened to prevent adhesion of dirt. (C) Clogging of the injection nozzle 50 can be prevented.

  The diaper cup 10 is formed of a transparent material. That is, by making the material of the diaper cup 10 to be worn on the lower back of the user 2 transparent, (1) confirmation of the wearing state; whether or not the diaper cup 10 is worn at a predetermined position by visual inspection.
