Description

Technical Field

[0001] This invention relates to a toilet device capable of calculating the state of urine and feces falling into the toilet bowl. Background Technology

[0002] Previously, toilet devices capable of calculating the state of urine or feces excreted from the body for health observation have been proposed. As a technique for calculating the state of urine, techniques using cameras have been proposed (for example, see Patent Document 1), and as a technique for calculating the state of feces, techniques based on measurements by radio wave sensors or water level meters have been proposed (for example, see Patent Documents 2 and 3).

[0007] Patent Document 3: Japanese Patent Application Publication No. 2016-64083 Summary of the Invention

[0008] The problem that the invention aims to solve

[0009] However, the techniques described above all calculate the state of either urine or feces, rather than both. Alternatively, it is conceivable to install one or more sensors on a toilet device to detect the state of both urine and feces. However, it may be impossible to distinguish between urine and feces, for example, in the case of watery stool, or the sensor's installation location may prevent proper detection of either.

[0010] The present invention was made in consideration of such circumstances, and its purpose is to provide a toilet device capable of calculating the state of urine and feces with high precision.

[0011] Methods used to solve problems

[0012] To achieve the above objectives, the toilet device of the present invention is characterized by comprising: a commode; a commode seat capable of being opened and closed; an opening / closing detection unit for detecting the opening / closing state of the commode seat; a falling object detection unit for detecting falling objects toward the commode; and a state calculation unit for calculating the state of at least one of feces and urine based on the information detected by the falling object detection unit; wherein the state calculation unit performs a urination calculation mode that calculates only the state of urine when the commode seat is in the open state, and performs a defecation calculation mode that calculates the state of at least one of feces and urine when the commode seat is in the closed state.

[0013] Invention Effects

[0014] The toilet device of the present invention is configured as described above, thus enabling highly accurate calculation of the states of urine and feces. In particular, it eliminates the possibility of misidentifying excrement as feces when urinating while standing. Attached Figure Description

[0022] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. First, the general basic structure of the toilet device 1 according to the embodiments will be described.

[0023] The toilet device 1 includes a bowl 12, an openable and closable toilet seat 21, and an opening / closing detection unit 22 for detecting the opening / closing state of the toilet seat 21. Furthermore, the toilet device 1 includes a falling object detection unit 23 for detecting objects falling onto the bowl 12, and a state calculation unit 24 for calculating the state of at least one of feces and urine based on the information detected by the falling object detection unit 23.

[0024] When the toilet seat 21 is in the open state, the state calculation unit 24 executes a urination calculation mode that only calculates the state of urine. On the other hand, when the toilet seat 21 is in the closed state, it executes a defecation calculation mode that calculates the state of at least one of defecation and urine.

[0025] Next, the toilet device 1 will be described in detail.

[0026] Figures 1 to 7 This is an explanatory diagram of toilet device 1. Additionally, Figure 2 (a) and (b) are schematic side views of the interior of two different types of toilet devices 1 with different cleaning methods (constructions). Either method is acceptable for toilet device 1.

[0027] The toilet device 1 is a seated Western-style toilet device that is fixed to the floor or wall in the toilet space. The main body 10 of the toilet device 1 is enclosed by a skirt 11 and contains a toilet bowl 12 that opens upward. On the upper side of the toilet bowl 12, there is a toilet seat 21 and a toilet cover 20 that can be stood up or folded down with respect to the opening of the toilet bowl 12 and have the same axis of rotation.

[0028] A toilet cleaning section 13 is disposed inside the skirt 11. The toilet cleaning section 13 discharges wastewater from the toilet bowl 12 and supplies cleaning water into the toilet bowl 12 from the water supply port 14 to clean the inside of the toilet bowl 12. The toilet cleaning section 13 has a water supply mechanism and a drainage mechanism.

[0029] The water supply system includes: a water inlet 14; a cleaning water supply passage 15, through which cleaning water supplied from a tap water pipe (not shown) is supplied to the toilet bowl 12; and a water supply valve 16, located in the middle of the cleaning water supply passage 15, for supplying or cutting off the water supply to the toilet bowl 12.

[0030] Figure 2 The drainage mechanism shown in (a) has a cylindrical, curved water trap 17 that extends rearward from the bottom of the toilet bowl 12. The water trap 17 extends further downward and connects to the drain outlet 18. Such drainage mechanisms include siphon type, jet siphon type, vortex siphon type, etc., which are mechanisms that form a drainage state or a water seal state through siphon action.

[0031] In addition, as a drainage mechanism, it can also have, for example, Figure 2 The movable drain trap 17A is shown in (b). The drain trap 17A is rotated in the direction of the arrow via a drive unit (not shown) to form either a drain state or a water-sealed state. In the illustration, the drain trap 17A is in the water-sealed state; in the drain state, it rotates so that the open end of the drain trap 17A faces the drain outlet 18. Furthermore, the drain trap 17A is surrounded by a drain trap shell (not shown) to prevent sewage or odors from leaking to the outside.

[0032] Alternatively, a drainage mechanism other than siphon or movable type can be used in toilet device 1, such as a flushing drainage mechanism.

[0033] Additionally, the illustration shows an example of a tankless toilet unit 1 that is directly connected to the water supply without a flush tank (low-level tank), but a structure with a flush tank can also be used.

[0034] The toilet unit 1, as described above, includes a falling object detection unit 23. This falling object detection unit 23 includes sensors such as a camera 23a, an electromagnetic wave sensor 23b (23ba, 23bb), a vibration sensor 23c, and an odor sensor 23d, which are installed at various locations on the toilet bowl 12. These sensors are only required to be installed at... Figure 2 The positions illustrated in (a) and (b) are sufficient.

[0035] The state calculation unit 24 executes either the urination calculation mode or the defecation calculation mode as described above, and is configured to calculate the amount of urine 32 in both modes. It also includes a urine volume calculation unit 24a for this purpose. This urine volume calculation unit 24a may have a structure that uses a camera 23a or a structure that utilizes the water level change of the stored water 31, etc., which will be described later.

[0036] Furthermore, the toilet device 1, as described above, includes an opening / closing detection unit 22 for detecting the opening / closing state of the toilet seat 21. The toilet device 1 also 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 opening / closing instructions from the toilet seat drive unit. Similarly, the toilet lid 20 includes a lid drive unit (not shown) and a lid operation unit (not shown).

[0037] In addition, the toilet device 1 also includes a seating detection unit 25 for detecting the sitting / leaving state of the toilet seat 21 and a human body detection unit 26 for detecting the state of a person entering the room.

[0038] The seating detection unit 25 may be, for example, a load sensor for detecting seating / leaving that is built into the toilet seat 21, or an infrared sensor for detecting seating / leaving that is located near the rotation axis of the toilet seat 21.

[0039] Furthermore, the toilet device 1 includes an operation unit 27. This operation unit 27 includes a toilet cleaning button and a urination cleaning button that output cleaning instructions to the toilet cleaning unit 13 via the control unit 5, as well as the aforementioned toilet seat operation unit and toilet lid operation unit. Preferably, the operation unit 27 is also provided on both the main operation unit (not shown) and the remote control (not shown). These are also equipped with operation switches and buttons for performing various operations and settings. As the remote control, a remote control using infrared communication is preferred.

[0040] The toilet device 1 includes a control unit 5, which controls the controlled objects (the water supply valve 16 of the toilet washing unit 13, the toilet seat drive unit, the toilet seat drive unit, etc.), and receives output signals from the operation unit 27, the opening / closing detection unit 22, the falling object detection unit 23, the human body detection unit 26, the sitting detection unit 25, etc. The control unit 5 is composed of a processor such as a CPU and an MPU, and various programs. The status calculation unit 24 operates under the control unit 5. The toilet device 1 also includes a timing unit (not shown) and a power supply unit (not shown).

[0041] Furthermore, the toilet device 1 includes a reporting unit 28, which is composed of a speaker or the like, to report malfunctions or statuses of the device and provide guidance via sound or sound synthesis. Alternatively, the reporting unit 28 may be a structure that replaces sound output or includes a display such as an LED.

[0042] The toilet unit 1 also includes a partial washing device 29. This partial washing device 29 performs posterior or feminine wash actions by spraying water based on the operation unit 27. These washes are performed by operating various switches provided on the operation unit 27.

[0043] Next, refer to Figures 3-7 The urine calculation mode and the urine and feces calculation mode of the state calculation unit 24 are explained.

[0044] The urine calculation model is a model that calculates the amount of urine in a man's urine when he urinates while standing (refer to...). Figure 3 (a) The urine and feces calculation mode is a mode that calculates the state of urine 32 and feces 33 when urinating and defecating while seated on the toilet seat 21 (see reference). Figure 3 (b)

[0045] In these modes, the aforementioned falling object detection unit 23 operates to detect urine 32 and feces 33, and the toilet device 1 calculates its status. Figure 3 Figures (a) and (b) are schematic diagrams illustrating examples captured by the sensor (camera 23a). The camera 23a operates identically in both the urine calculation mode and the urination / defecation calculation mode, with the shooting range differing for each mode. Regardless of the mode, the falling urine 32 and feces 33 are captured, and the camera 23a is driven and controlled by a drive unit (not shown) that is also provided, without capturing any parts of the human body.

[0046] These patterns are all achieved by sensors constituting the falling object detection unit 23 collecting information on the falling urine 32 and feces 33, and calculating their states based on the information collected by the state calculation unit 24. Preferably, these detection actions are performed periodically.

[0047] Furthermore, it is preferable to use different detection methods for the sensors constituting the falling object detection unit 23 for each mode. For example, in the urination calculation mode, the camera 23a, the radio wave sensor 23b, and the thermopile (not shown) are activated; in the urination / defecation calculation mode, only the camera 23a, the radio wave sensor 23b, and the vibration sensor 23c need to be activated. Figure 3 As explained in the text, the same camera 23a can also be made to operate in different ways.

[0048] The measurements performed by these sensors can be initiated based on trigger events such as the room entry timing obtained by the human body detection unit 26. Alternatively, the measurement can be initiated when the opening and closing of the toilet seat 21 changes after entering the room. Since the urination / defecation calculation mode is the mode executed when the toilet seat 21 is closed, the measurement can also be initiated by the sitting time.

[0049] The measurement performed by the falling object detection unit 23 (sensor) can be completed by setting the departure time from the room as obtained by the human body detection unit 26. Alternatively, the measurement can be performed in accordance with the execution of each mode.

[0050] In this way, the measurement actions performed by the sensor only need to be performed from the time the toilet is entered until the toilet is left, or whenever the toilet is used for defecation or urination, i.e. whenever the state calculation unit 24 executes the mode. By doing so, the sensor detection and power supply can be stopped when the toilet is not in use, thus saving energy.

[0051] These two modes will not be executed simultaneously. The mode to be executed is determined by checking the open / closed state of the toilet seat 21, as described above. Below, along with... Figure 4 and Figure 5 The flowcharts for each of these patterns provide detailed explanations of their execution.

[0052] If measurement begins, the state calculation unit 24 determines the open / closed state of the toilet seat 21 detected by the opening / closing detection unit 22. If the toilet seat 21 is open, the urination calculation mode is executed until cleaning begins. Figure 4 (S101 "Yes", S102, S103).

[0053] This urine calculation mode simply needs to be executed periodically until the cleaning process begins. For example, it can perform periodic shooting by camera 23a or time-series data collection from other sensors. After the cleaning process begins, if it's necessary to aggregate or edit the collected information, these processes can be performed. Figure 4(S103 "Yes", S104). Of course, in periodic processing, it is also possible to simply collect the time series of information detected by the falling object detection unit 23. In addition, as the start of cleaning, the control unit 5 can detect the signal to start the cleaning operation.

[0054] When the toilet seat 21 is not in the open state, the status calculation unit 24 then determines whether the person is seated. If the person is seated, the urination and defecation calculation mode is executed until the cleaning begins. Figure 4 (S101 "No", S105 "Yes", S106, S107).

[0055] In this urine and feces calculation mode, just like in the urine calculation mode, it is executed periodically until the cleaning begins, and then the collected information is aggregated and edited as needed (S107 "Yes", S108).

[0056] Additionally, if the toilet seat 21 is determined to be closed and the person is not seated, neither the urination / defecation calculation mode nor the defecation calculation mode will be executed. Figure 4 (No in S101, No in S105).

[0057] according to Figure 4 If a mode is determined in the state judgment of toilet seat 21, then that mode will be executed during the period until the cleaning begins. However, it can also be performed as follows: Figure 5 As shown, the mode is switched whenever the toilet seat 21 is opened or closed during the period from the start of cleaning to the end of the measurement.

[0058] Specifically, if measurement begins, the state calculation unit 24 determines the open / closed state of the toilet seat 21 detected by the opening / closing detection unit 22 during the period until the measurement ends. If the toilet seat 21 is in the open state, the urination calculation mode is executed. Figure 5 (S201, S202, "yes", S203).

[0059] When the toilet seat 21 is not in the open state, the state calculation unit 24 then determines whether the person is seated. If the person is seated, the urination / defecation calculation mode is executed. Figure 5 S202 "No", S204 "Yes", S205). If the toilet seat 21 is not open and the person is not seated, none of the modes are executed. Figure 5 (No in S202, No in S204).

[0060] If the measurement is complete, then you can perform sub-mode summarization and editing of the information collected in the urination calculation mode and the urination / defecation calculation mode. Figure 5S201 "Yes", S206). Information regarding the interrelationship between urine collection information 32 in the urination calculation mode and stool collection information 33 in the defecation and urination calculation mode, in data editing ( Figure 5 You can perform processing and editing within S206. Additionally, regarding... Figure 5 You can also set all modes to periodic processing.

[0061] according to Figure 5 In cases where there is no cleaning during the period from the start to the end of the measurement, but there is a switch between standing and sitting urination by opening and closing the toilet seat 21, the information collection is less likely to be missed due to the different modes of execution for both parties.

[0062] As described above, since the urine calculation mode and the defecation calculation mode are determined based on the open or closed state of the toilet seat 21, the states of urine 32 and feces 33 can be calculated with high accuracy. In particular, when urinating in a standing position with the toilet seat 21 open, it can prevent the excrement from being mistaken for feces 33.

[0063] Alternatively, the sitting status can be ignored in the urine and feces calculation mode judgment. As long as the toilet seat 21 is closed (i.e., as long as it is not urine calculation mode), the urine and feces calculation mode can be executed.

[0064] Next, specific examples of the calculation of the state of urine 32 performed by the state calculation unit 24 under each mode will be explained.

[0065] Regarding urine 32 in the urination calculation mode, it can be captured periodically by camera 23a (at a period of 200 msec, etc.). The urine volume calculation unit 24a of the status calculation unit 24 collects the captured images and calculates the color or volume and urination time based on the images or the number of images, and performs various analyses (diagnoses) based on these. For example, based on the color of urine 32 in the image, if it is light yellow or light yellowish-brown, it is judged as healthy; if it is other colors, the cause can be determined based on its color.

[0066] For example, the following diagnosis can be made.

[0067] Yellow or amber color...hepatitis, gallstones

[0068] Red or brownish-red... ureteral stones, hemorrhagic cystitis

[0069] White…nephrotic syndrome, high-grade pyuria

[0070] Blue or green... anesthetics, antidepressants, or cystitis

[0071] Brown or black... medication for Parkinson's disease.

[0072] In addition, odor sensors can also be used to make diagnoses based on the smell of urine.

[0073] In addition, the state calculation unit 24 can also collect raw data (images or values) detected by the falling object detection unit 23 (sensor) in time series only. The state judgment and calculation based on this raw data can also be performed by a person directly observing the images or values.

[0074] Furthermore, the amount of urine 32 can be determined based on the number of images. Alternatively, the velocity of urine 32 can be calculated using the radio wave sensor 23b, and the amount can be calculated based on the number of images and the velocity. Furthermore, a more accurate amount can be calculated by detecting the thickness of urine 32 based on the images.

[0075] Based on the actions of the image-based state calculation unit 24, interruptions in urination can also be detected. For example, if a temporary interruption in urination is detected based on the periodic image, and urination continues for more than 2 seconds after the interruption, it can be determined that there has been an interruption in urination. By detecting interruptions in urination in this way, urination disorders can be detected earlier. In addition, the number of interruptions, the duration of interruptions, and the momentum of urination can also be calculated.

[0076] Furthermore, the urine volume calculation unit 24a may also include a water level sensor (not shown) to calculate urine volume based on changes in the water level of the accumulated water 31 in the bedpan 12. When using this unit, the premise is as follows... Figure 2 As shown in (a) and (b), the water level of the water 31 stored in the traps 17 and 17A does not reach the upper limit during normal use. If this is the case, the urine volume can also be calculated using this unit as long as the water in the bedpan 12 and the traps 17 and 17A does not exceed the upper limit and flow out to the drain outlet 18 through urination.

[0077] The appropriate amount of urine for one urination is set to approximately 200-400 ml, which corresponds to a urine volume of approximately 300-400 ml that can be stored in the bladder. Therefore, the status calculation unit 24 can also determine whether the amount of urine is appropriate based on the calculated amount of urine each time urination occurs, and the reporting unit 28 will report it.

[0078] Regarding urine 32 in the urination / defecation calculation mode, its color or quantity can be calculated using images obtained from camera 23a or radio wave sensor 23b. Furthermore, in the urination / defecation calculation mode, the distinction between urination and defecation is made based on the width and color of the falling object. Additionally, such as... Figure 3 As shown in (b), the falling position is different in urination and defecation, so the camera 23a can capture the water surface of the accumulated water 31 and determine whether it is urine or feces based on the falling position of the excrement on the water surface in the image.

[0079] Regarding the feces 33 in the defecation calculation mode, the color, shape, and quantity can be calculated based on continuous periodic images from camera 23a. Alternatively, other radio wave sensors can be used to determine the thickness of the feces 33 at a specific height position, and then the speed, based on which the quantity or shape of the feces 33 can be calculated.

[0080] For example, it can also be used Figure 6 The calculation algorithm is shown in the schematic diagrams (a) and (b). Radio wave sensor 23ba (also refer to...) Figure 2 (a) and (b) are sensors that detect the thickness of the surface (hypothetical detection surface 35) at a specific height position of the excreted feces 33. For example, if an electromagnetic wave sensor 23ba is provided to transmit electromagnetic waves approximately parallel to the mounting surface of the toilet device 1, the hypothetical detection surface 35 is preferably positioned at approximately the same height as the electromagnetic wave sensor 23ba. Figure 6 (a) is a perspective view schematically showing the positional relationship between the radio wave sensor 23ba, the imaginary detection surface 35, and the feces 33 passing through the imaginary detection surface 35.

[0081] like Figure 6 As shown in (a), the radio wave sensor 23ba can measure and calculate the width dimension information of the front (one side) of the feces 33 by means of radio wave-based measurement. If it is desirable to more accurately detect the overall shape or quantity (volume) of a single feces 33 based on the width dimension information, it is preferable to provide two radio wave sensors 23ba so that the width dimension information of both sides can be measured. That is, if there are two radio wave sensors 23ba, the cross-sectional area of ​​the feces 33 can be calculated more accurately.

[0082] The radio wave sensor 23ba is configured to detect the presence or absence of an object (feces 33) passing through the imaginary detection surface 35 by using emitted radio waves and reflected waves that strike the surface of the feces 33 and are reflected back, per unit surface 35a (one unit of the imaginary detection surface 35), and to detect width dimension information. This width dimension information is preferably expressed in actual dimensions, i.e., mm (millimeters) or cm (centimeter), but it can also be information that can be expressed in units specific to this toilet device 1.

[0083] For example, it can also be Figure 6 The small square face shown in (a) is designated as a unit face 35a, and the length of one side of it is represented by "one side length" ("side length" is a temporarily defined unit). The width of the feces 33 is expressed as an integer multiple of one side length. If this one side length is predetermined with values ​​such as one side length = 3mm, 5mm, 10mm, etc., the size of the feces 33 can be calculated. In addition, it goes without saying that if there is only one radio wave sensor 23ba, even if there are two, errors may still occur in the calculated width or volume.

[0084] The radio wave sensor 23ba periodically detects feces 33 in the imaginary detection surface 35 (detection of width dimension information). Based on the radio wave sensor 23ba, in addition to detecting width dimension information (thickness), it is also possible to calculate the volume of one piece of feces 33 and the passage time of one piece of feces through the imaginary detection surface 35. Furthermore, it is also possible to calculate the total time from the first piece of feces 33 passing through to the last piece of feces passing through in one defecation cycle, the number of pieces of feces 33 in one defecation cycle, and the total volume of multiple pieces of feces 33 in one defecation cycle.

[0085] Figure 6 (b) is a diagram schematically showing the falling state of feces 33 detected at unit time intervals relative to the hypothetical detection surface 35. Here, Figure 6 (b) t1, t2, ... t k , ...t n It is the time of each unit time interval.

[0086] Figure 6 The radio wave sensor 23bb shown in (b) is a sensor that illuminates the front end (lower end) of the feces 33 with radio waves and calculates the falling speed of the feces based on the transmitted and reflected waves. For example, the falling speed can be detected by illuminating the front end of the feces 33 that reaches the imaginary detection surface 35 with radio waves at a timing of t1. The falling speed detected in this way can be set as the falling speed of each imaginary detection surface 35 and then assigned to the falling speed of the information passing through.

[0087] In addition, regarding the falling speed, it can also be found in Figure 6 In (b), from t1 to t n The entire timer is used to measure the falling speed, allowing for the detection of changes in the falling speed at unit time intervals. Furthermore, this can be achieved by simply installing an electromagnetic wave sensor that can change the delivery direction in response to changes in the height of the feces 33 at its front end.

[0088] As an example of image-based state calculation performed by the state calculation unit 24, a trait classification based on the shape of the feces 33 can be given. Figure 7 This is a trait classification table that associates shape images with each trait of the model poop 37. Traits are classified as follows.

[0089] NO.1 Ball-shaped droppings (hard, ball-shaped rabbit droppings)

[0090] NO.2 Hard stool (sausage-shaped, hard stool)

[0091] NO.3 Slightly hard stool (stool with cracks on the surface, resembling a sausage)

[0092] NO.4 Normal stool (smooth and soft, sausage-shaped or coiled stool)

[0093] NO.5 Slightly soft stool (soft, semi-solid stool with clear wrinkles)

[0094] NO.6 Muddy stool (small, irregularly shaped, muddy stools with indistinct borders)

[0095] NO.7 Watery stool (watery, liquid stool without solids)

[0096] The state calculation unit 24 compares the image of the actual feces 33 with the shape image of the model feces 37 in the trait classification table to find the approximate trait. Alternatively, the trait can be determined by extracting features from the image of feces 33 without using such a shape image of model feces 37.

[0097] When defecation occurs once a day, the appropriate amount of stool for one defecation is set to 100-200g. Therefore, the status calculation unit 24 can also determine whether the calculated amount of stool is appropriate each time defecation and report it by the reporting unit 28.

[0098] Furthermore, the state calculation unit 24 can also determine the state of the stool 33 based on the posterior washing time calculated by the local cleaning device 29. For example, the analysis of the posterior washing time can supplement or replace the morphological calculation of the shape image of the model stool 37 based on the morphological classification table.

[0099] As a specific method for calculating the posterior washing time, the control unit 5 or the control unit of the local cleaning device 29 can time the time from the start of water spraying by the local cleaning device 29 during posterior washing to the end of water spraying. Alternatively, the posterior washing time can also be calculated by timing the time from the start of water spraying operation to the end of water spraying operation. Furthermore, the posterior washing time can also be calculated using continuous periodic images obtained by the camera 23a.

[0100] Furthermore, in the illustration, this toilet device 1 has an odor sensor 23d on the inside of the toilet seat 21, which can measure urinary or fecal gases and calculate the type and intensity of the odor. For example, by measuring the intensity of fecal gases such as methane, it is possible to detect serious diseases such as cancer early. In addition, the odor sensor 23d can also be set separately for urine 32 and feces 33.

[0101] The state calculation unit 24 can make various judgments as needed based on the color, shape, amount, odor, etc. of the stool 33 obtained as described above. Alternatively, the state calculation unit 24 can collect only the raw data in the time series.

[0102] As described above, the states of urine 32 and feces 33 calculated by the state calculation unit 24 include various state elements. The following combinations can be cited as examples of the two states of urine and feces.

[0103] • The state of urine 32 includes at least one of the following: amount, time of urination, color, odor, and whether or not urination is interrupted; the state of feces 33 includes at least one of the following: shape, amount, consistency, color, texture, odor, and time of urination.

[0104] • As a state of urine 32, it includes at least one of color, amount, and time of urination; as a state of feces 33, it includes at least one of shape, amount, and consistency.

[0105] • As a state of urine 32, it includes color; as a state of feces 33, it includes both shape and color.

[0106] • As a state of urine 32, it includes at least one of color, amount, time of urination, and odor; as a state of feces 33, it includes odor.

[0107] These are just one example; the states of urine 32 and feces 33 can also include various other state elements. Furthermore, various combinations of the states of urine 32 and feces 33 can be conceived. Of course, it could also be a toilet device 1 that calculates the state of either urine 32 or feces 33.

[0108] As described above, regardless of whether it is the urine calculation mode or the urination and defecation calculation mode, it is about judging the color or amount and the time of urination of urine 32, and about judging the color or shape and amount of defecation 33.

[0109] The information collected and calculated by the status calculation unit 24 is preferably stored in the toilet device 1 or an external device by establishing a connection for each user. For example, information such as urine volume, urination frequency, stool volume, defecation frequency, and other statuses of the user during a specified period (e.g., 1 day) can also be calculated.

[0110] If the collected information and other computational data are linked and stored for each user, health management for each user can also be achieved. To identify the user, the toilet device 1 only needs to register an identification code, age, weight, etc., and the user can input the identification code during use.

[0111] The data collected and calculated as described above, especially the judgment results, are preferably reported by the reporting unit 28 via sound and display after the toilet is cleaned. Alternatively, data for one day can be summarized or aggregated and displayed via an external device such as a smartphone. Furthermore, from a privacy perspective, it is preferable not to display raw data (especially images), and if display is necessary, it is preferable to require authorization via the input of a specific password.
