Next, the details of the toilet bowl device 1 will be described.

1 to 7 are explanatory views of the toilet bowl device 1. Note that FIGS. 2A and 2B are schematic side views schematically showing the inside of the toilet bowl device 1 showing two forms in which the cleaning methods (structures) are different. It may be of the method of.

The toilet bowl device 1 is a stool-type Western-style toilet bowl device fixed to a floor, a wall, or the like in the toilet space. The main body 10 of the toilet bowl device 1 is internally designed so that the bowl 12 opened upward is surrounded by the skirt portion 11, and the upper side of the bowl 12 is vertically retractable with respect to the opening surface of the bowl 12. A toilet seat 21 and a toilet lid 20 having the same rotation axis are provided.

In the internal space of the skirt portion 11, a toilet bowl cleaning portion 13 that discharges the sewage in the bowl 12 and supplies washing water into the bowl 12 from the water supply port 14 to clean the inside of the bowl 12 is arranged. The toilet bowl cleaning unit 13 has a water supply mechanism and a drainage mechanism.

The water supply mechanism is arranged in the middle of the water supply port 14, the washing water supply path 15 for supplying the washing water supplied from the water pipe (not shown) into the bowl 12 through the water supply port 14, and the washing water supply line 15. It is provided with a water supply valve 16 that supplies or shuts off the water supply to the bowl 12.

The drainage mechanism shown in FIG. 2A has a cylindrical bent trap 17 connected so as to extend rearward from the bottom of the bowl 12, and the trap 17 extends further downward and connects to the drainage port 18. Has been done. Examples of this type of drainage mechanism include a siphon type, a siphon set type, and a siphon vortex type, which are considered to be a mechanism in which a drainage state or a water sealing state is formed by a siphon action.

Further, the drainage mechanism may have a structure having a movable trap 17A as shown in FIG. 2 (b). The trap 17A is rotated in the direction of an arrow by a driving unit (not shown) to form a drainage state or a water sealing state. The trap 17A in the illustrated example is in the position in the sealed state, and in the drainage state, the trap 17A rotates so that the open end of the trap 17A faces the drain port 18. The trap 17A is surrounded by a trap case (not shown) so that sewage and odor do not leak to the outside.

Further, a drainage mechanism that is neither a siphon type nor a movable type, for example, a wash-off type drainage mechanism can be applied to the toilet bowl device 1.

Further, in the illustrated example, the toilet bowl device 1 is shown as a tankless type directly connected to the water supply without a water washing tank (low tank), but a water washing tank may be provided.

As described above, the toilet bowl device includes a falling object detection unit 23. The falling object detection unit 23 includes sensors such as a camera 23a, a radio wave sensor 23b (23ba, 23bb), and a vibration sensor 23c provided at various positions of the bowl 12. These sensors may be provided at the positions illustrated in FIGS. 2 (a) and 2 (b).

As described above, the state calculation unit 24 executes either the small calculation mode or the large / small calculation mode. In either case, the state calculation unit 24 is configured to calculate the amount of urine 32, and is provided with a urine volume calculation means for that purpose. The urine volume calculating means 24a includes a camera 23a and a water level change of the stored water 31, which will be described later.

Further, as described above, the toilet device 1 includes an open / close detection unit 22 that detects the open / closed state of the toilet seat 21. The toilet device 1 further includes a toilet seat drive unit (not shown) that electrically drives the toilet seat 21 and a toilet seat operation unit (not shown) that receives a closing instruction for the toilet seat drive unit. Similarly, the toilet lid 20 is provided with a toilet lid driving unit (not shown) and a toilet lid operating unit (not shown).

Further, the toilet device 1 further includes a seating detection unit 25 that detects a sitting / leaving state with respect to the toilet seat 21, and a human body detecting unit 26 that detects a person's entry state.

As the seating detection unit 25, for example, a load sensor for detecting seating / leaving, an infrared sensor for detecting seating / leaving from the vicinity of the rotation shaft portion of the toilet seat 21, and the like, which are built in the toilet seat 21, are adopted.

Further, the toilet device 1 includes an operation unit 27. The operation unit 27 includes a stool cleaning button and a urine cleaning button that output a cleaning instruction to the toilet bowl cleaning unit 13 via the control unit 5, a toilet seat operation unit, a toilet lid operation unit, and the like described above. There is. It is desirable that the operation unit 27 is arranged on either the main body operation unit (not shown) or the remote controller (not shown). These are also provided with operation switches and operation buttons that allow various operations and settings. As the remote controller, an infrared communication remote controller is preferably used.

The toilet device 1 controls the control target (water supply valve 16 of the toilet cleaning unit 13, toilet lid drive unit, toilet seat drive unit, etc.), while the operation unit 27, open / close detection unit 22, falling object detection unit 23, and human body detection. It includes a control unit 5 that receives output signals from the unit 26, the seating detection unit 25, and the like. The control unit 5 includes a processor such as a CPU and an MPU and various programs. The state calculation unit 24 operates under the control unit 5. The toilet bowl device 1 further includes a time measuring unit (not shown) and a power supply unit (not shown).

Further, the toilet bowl device 1 includes a notification unit 28 including a speaker that notifies an abnormality or state of the device and guidance by sound or voice synthesis. The notification unit 28 may be configured to include a display such as an LED in place of or in addition to the sound output unit.

Next, the small calculation mode and the large / small calculation mode of the state calculation unit 24 will be described with reference to FIGS. 3 to 7.

The small calculation mode is a mode for calculating the state of the male urine 32 when urinating in a standing position (see FIG. 3 (a)), and the large / small calculation mode is a mode for urinating and defecation while sitting on the toilet seat 21. In this mode, the states of urine 32 and stool 33 are calculated (see FIG. 3B).

In these modes, the fallen object detection unit 23 described above operates, urine 32 and stool 33 are detected, and the toilet device 1 calculates the state. FIGS. 3 (a) and 3 (b) schematically show an example of taking a picture with a sensor (camera 23a), and the same camera 23a operates in both the small calculation mode and the large / small calculation mode, and each mode I try to make the shooting range different. In either mode, the camera 23a is driven and controlled by a parallel drive unit (not shown) so that the falling urine 32 and the stool 33 are targeted for imaging and the local part of the human body is not photographed. ..

In each of these modes, the sensor constituting the falling object detection unit 23 collects information on the falling urine 32 and the stool 33, and the state calculation unit 24 calculates those states based on the collected information. It is desirable that these detection operations be performed periodically.

Further, it is desirable that the detection mode of the sensor constituting the falling object detection unit 23 is different for each mode. For example, in the small calculation mode, the camera 23a, the radio wave sensor 23b, and the thermopile (not shown) may be operated, and in the large / small calculation mode, the camera 23a, the radio wave sensor 23b, and the vibration sensor 23c may be operated. As described with reference to FIG. 3, the same camera 23a may be operated in different modes.

The measurement by these sensors may be started by a trigger such as the entry timing by the human body detection unit 26. Further, the measurement may be started at the timing when the opening / closing of the toilet seat 21 is changed after entering the room. Since the magnitude calculation mode is the execution mode when the toilet seat 21 is used in the closed state, the seating timing may be set as the measurement start.

The end of the measurement by the falling object detection unit 23 (sensor) may be the timing of leaving the room by the human body detection unit 26. Further, the measurement may be performed according to the execution of each mode.

In this way, the measurement operation by the sensor may be performed from entering the room to leaving the room, or every time defecation or urination, that is, each time the state calculation unit 24 executes the mode. By doing so, it is possible to stop the sensor detection, power supply, etc. when the toilet is not in use, and power saving can be achieved.

These two modes cannot be executed at the same time. The mode to be executed is determined by determining the open / closed state of the toilet seat 21 as described above. Hereinafter, the execution of these modes will be described in detail with reference to the flowcharts of FIGS. 4 and 5.

When the measurement is started, the state calculation unit 24 determines the open / closed state of the toilet seat 21 detected by the open / close detection unit 22, and if the toilet seat 21 is in the open state, executes the small calculation mode until the cleaning is started (FIG. 4). S101 Y, S102, S103).

This small calculation mode may be executed periodically until the start of cleaning. For example, periodic photography by the camera 23a, time-series collection of periodic data by another sensor, and the like may be executed. If it is necessary to add up or edit the collected information after the cleaning is started, it may be performed (Y, S104 in S103 of FIG. 4). Of course, in the periodic processing, only the time-series collection of the information detected by the falling object detection unit 23 may be performed. Further, as the cleaning start, a signal obtained by the control unit 5 detecting the cleaning start operation may be used.

When the toilet seat 21 is not in the open state, the state calculation unit 24 then determines whether or not the toilet seat 21 is seated, and if it is seated, executes the magnitude calculation mode until the cleaning is started (S101 in FIG. 4). N, Y of S105, S106, S107).

Similar to the small calculation mode, this large / small calculation mode may be executed periodically until the start of cleaning, and then the collected information may be added up, edited, etc. as necessary (Y in S107). , S108).

If it is determined that the toilet seat 21 is closed and not seated, neither the magnitude calculation mode nor the minor calculation mode is executed (N in S101 and N in S105 in FIG. 4).

According to the operation of FIG. 4, if one mode is determined by the state determination of the toilet seat 21, that mode is executed until the cleaning is started. As shown in FIG. 5, the measurement such as the cleaning start is performed. The mode may be switched each time the toilet seat 21 is opened or closed until the end.

Specifically, when the measurement is started, the state calculation unit 24 determines the open / closed state of the toilet seat 21 detected by the open / close detection unit 22 until the measurement is completed, and if the toilet seat 21 is in the open state, it is small. The calculation mode is executed (S201 in FIG. 5, Y in S202, S203).

When the toilet seat 21 is not in the open state, the state calculation unit 24 then determines whether or not the toilet seat 21 is seated, and if it is seated, executes the magnitude calculation mode (N, S204 in S202 of FIG. 5). Y, S205). If the toilet seat 21 is not in the open state and is not seated, neither mode is executed (N in S202 and N in S204 in FIG. 5).

When the measurement is completed, the summing, editing, and the like may be executed for each mode of the information collected in the small calculation mode and the large / small calculation mode (Y, S206 in S201 of FIG. 5). If the collected information of urine 32 in the small calculation mode and the collected information of the stool 33 in the large / small calculation mode are related to each other, if the data is edited (S206 in FIG. 5), processing or editing is executed. good. As for FIG. 5, it is sufficient that periodic processing is performed in each mode.

According to the operation of FIG. 5, both modes are executed even if there is a switch between standing urination and sitting excretion by opening and closing the toilet seat 21 without washing between the start and the end of the measurement. Collection leakage is unlikely to occur.

As described above, since the small calculation mode and the large / small calculation mode are discriminated by the open / closed state of the toilet seat 21, the respective states of the urine 32 and the stool 33 can be calculated accurately. In particular, in the case of standing urination when the toilet seat 21 is open, it is possible to prevent the excrement from being erroneously determined to be stool 33.

In addition, in the determination of the magnitude calculation mode, if the toilet seat 21 is closed (that is, it is not the minor calculation mode), the magnitude calculation mode may be executed without determining the seated state.

Next, a specific example of calculating the state of the urine 32 by the state calculation unit 24 in each mode will be described.

The urine 32 in the small calculation mode may be photographed by the camera 23a periodically (200 msec cycle or the like). The urine volume calculation means 24a of the state calculation unit 24 may collect captured images, calculate the color, amount, and urination time from the images and the number of images, and perform various analyzes (diagnosis) based on them. .. For example, based on the color of urine 32 in the image, if it is pale yellow or pale yellowish brown, it may be determined that it is healthy, and if it is another color, the cause may be determined based on that color.

For example, the following diagnosis can be made.
Yellow or amber ... Hepatitis, Cholelithiasis Red or brown ... Urolithiasis, Hemorrhagic cystitis White: Nephrose syndrome, severe pyuria Blue or green: Taking anesthetics or antidepressants Cystitis Brown or black ... Taking a drug for treating Parkinson's disease Also, since diagnosis can be made by the smell of urine, an odor sensor may be used.

The state calculation unit 24 may only collect raw data (images and numerical values) detected by the falling object detection unit 23 (sensor) in chronological order, and a person directly collects the images and numerical values for the state judgment and calculation based on them. You can also judge by looking at it.

Further, the amount of urine 32 may be determined by the number of images. Alternatively, the speed of urine 32 may be calculated using a radio wave sensor, and the amount may be calculated based on the number of images and the speed. Further, by detecting the thickness of the urine 32 from the image, a more accurate amount can be calculated.

Further, the urine volume calculating means 24a may further include a water level sensor (not shown) and calculate the urine volume by changing the water level of the stored water 31 in the bowl 12. When this means is used, it is premised that the water level of the pooled water 31 in the traps 17 and 17A does not reach the upper limit in normal use as shown in FIGS. 2A and 2B. Then, as long as the water in the bowl 12 and the traps 17 and 17A does not flow out to the drain port 18 by urination, the urine volume can be calculated by this means as well.

The appropriate amount of urine for one urination is about 200 to 400 ml so as to correspond to the amount of urine that can be stored in the bladder, about 300 to 400 ml. Whether or not it is appropriate may be determined based on the amount of urine, and the notification unit 28 may notify the notification.

For the urine 32 in the magnitude calculation mode, the color and amount may be calculated using an image taken by the camera 23a, a radio wave sensor, or the like. In the magnitude calculation mode, urination and defecation may be discriminated by the width dimension of the falling object, the color of the falling object, and the like. Further, as shown in FIG. 3B, since the drop position differs between urination and defecation, the camera 23a is used to take a picture so as to include the water surface of the pooled water 31, and the drop position of the excrement in the image to the water surface. It is also possible to distinguish between urine and stool.

For the flight 33 in the magnitude calculation mode, the color, shape, and amount can be calculated from the continuous periodic image of the camera 23a. It is also possible to obtain the thickness of the stool 33 at a specific height position using the radio wave sensor, further obtain the speed, and calculate the amount and shape of the stool 33 from them.

For example, a calculation algorithm as shown in the schematic diagram of FIGS. 6A and 6B may be used. The radio wave sensor 23ba (see also FIGS. 2A and 2B) is a sensor that detects the thickness of the excreted and falling stool 33 at a specific height position (virtual detection surface 35). For example, if the radio wave sensor 23ba is installed so that the radio waves are transmitted substantially parallel to the installation surface of the toilet bowl device 1, it is desirable that the virtual detection surface 35 is arranged at a position substantially the same height as the radio wave sensor 23ba. FIG. 6A is a perspective view schematically showing the positional relationship between the radio wave sensor 23ba, the virtual detection surface 35, and the flight 33 passing through the virtual detection surface 35.

As shown in FIG. 6A, the radio wave sensor 23ba can measure and calculate the width dimension information of the front surface (1 side surface) of the stool 33 by the measurement by the radio wave. Considering that the overall shape and amount (volume) of one stool 33 can be detected more accurately based on the width dimension information, it is possible to provide two radio wave sensors 23ba so that the width dimension information on the two sides can be measured. desirable. That is, if there are two radio wave sensors 23ba, the cross-sectional area of the stool 33 can be calculated more accurately.

The radio wave sensor 23ba uses the transmitted radio wave and the reflected wave that hits the surface of the stool 33 and is reflected and returned to determine the presence or absence of an object (stool 33) that passes through the virtual detection surface 35 as a unit surface 35a (virtual detection surface). It is configured to detect every 1 unit of 35) and detect the width dimension information. This width dimension information is preferably expressed in actual dimensions, that is, in mm (millimeters) and cm (centimeters), but may be expressed in a unit peculiar to the toilet bowl device 1.

For example, the small square surface shown in FIG. 6A is defined as one unit surface 35a, and the length of one side thereof is represented by "one side length" ("side length" is a tentatively agreed unit), and the width of the stool 33. The dimension may be expressed as an integral multiple of the side length. If the one-side length is numerically determined in advance, for example, one-side length = 3 mm, 5 mm, 10 mm, etc., the dimension of the stool 33 can be finally calculated. Needless to say, when there is only one radio wave sensor 23ba, even if there are two, there is a possibility that an error may occur in the calculated width dimension and volume.

The radio wave sensor 23ba periodically detects the stool 33 (detects the width dimension information) on the virtual detection surface 35. According to the radio wave sensor 23ba, in addition to detecting the width dimension information (thickness), it is possible to calculate the volume of one stool 33 and the passage time of the virtual detection surface 35 of one stool 33. In addition, the total time from the start of passage of the first stool 33 in one defecation to the end of passage of the last stool 33, the number of individuals of stool 33 in one defecation, and a plurality of stools 33 in one defecation. It is also possible to calculate the total volume of.

FIG. 6B is a diagram schematically showing a falling state of the stool 33 with respect to the virtual detection surface 35 detected at each unit time interval. _{Here, t 1} , t ₂ , ... t _k , ... t _n in FIG. 6 (b) are times for each unit time interval.

The radio wave sensor 23bb shown in FIG. 6B applies a radio wave to the tip (lower end) of the stool 33 and calculates the falling speed of the stool from the transmitted wave and the reflected wave. For example, at timing t _1, it relies on radio waves to the tip of the stool 33 reaching the imaginary detection plane 35, may be detected falling speed. The fall speed detected in this way may be assigned to the fall speed of the passing information as the fall speed for each virtual detection surface 35.

_{Further, the falling speed may be measured at all timings from t 1 to t n} in FIG. 6 (b) so that the falling speed changing at each unit time interval can be detected. For that purpose, a penetration sensor may be provided so that the delivery direction can be changed so as to correspond to the tip of the stool 33 whose height position changes.

Examples of the state calculation based on the image performed by the state calculation unit 24 include property classification based on the shape of the stool 33. FIG. 7 is a property classification table of model flight 37 in which shape images are associated with each property. The properties are classified as follows.

NO. 1 Rolling stool (hard and rolling rabbit feces-like stool)
NO. 2 Hard stool (sausage-like hard stool)
NO. 3 Slightly hard stool (sausage-like stool with cracks on the surface)
NO. 4 Ordinary stool (sausage-like stool with a smooth and soft surface, or stool with a stool)
NO. 5 Slightly soft stool (soft semi-solid stool with clear wrinkles)
NO. 6 Muddy stool (unraveled, irregularly shaped small piece of muddy stool)
NO. 7 Watery stool (watery, solid-free liquid stool)

The state calculation unit 24 may compare the image of the actual stool 33 with the shape image of the model stool 37 in the property classification table to find out the approximate property. Further, instead of using such a shape image of the model stool 37, features may be extracted only from the image of the stool 33 to determine the properties.

When the amount of defecation is once a day, the appropriate amount of stool for one defecation is 100 to 200 g. Therefore, the state calculation unit 24 determines whether or not the calculated amount of stool is appropriate for each defecation. The notification unit 28 may notify the notification.

The state calculation unit 24 may make various determinations as necessary based on the color, shape, and amount of the stool 33 obtained as described above. Further, the state calculation unit 24 may only collect raw data in time series.

As described above, in either the small calculation mode or the large / small calculation mode, an appropriate determination is made regarding the color, amount, urination time, etc. of the urine 32, and the color, shape, amount, etc. of the stool 33.

It is desirable that the information collected and calculated by the state calculation unit 24 be associated with each user and stored in the toilet bowl device 1 or an external device. For example, urine volume, urine frequency, stool volume, stool frequency, and other status calculation information for a predetermined period (for example, one day) may be aggregated for each user.

By associating and storing the collected information and other calculated data for each user in this way, it is possible to manage the health of each user. In order for the toilet device 1 to determine the user, an identification code, age, weight, etc. that can identify an individual may be registered in the toilet device 1, and the identification code may be input when the toilet device 1 is used. ..

It is desirable that the data collected and calculated as described above, particularly the judgment result, be notified by voice or display by the notification unit 28 after cleaning the toilet bowl. In addition, daily data and the like may be collected or added up and displayed through an external device such as a smartphone. It is desirable not to display raw data (especially images) from the viewpoint of privacy protection, and it is desirable to display it on the premise that it is accepted by entering a specific password.
