Abstract

The toilet seat system is cleaned. The washing toilet seat system has a toilet seat (10) on which a user sits, and a urine detection unit (1) for detecting urine. The urine detection unit (1) is designed with an infrared detection area (2) so that the fallen urine (3) reliably passes through the detection area (2). Further, since the flow of urine when seated on the toilet seat (10) is along the surface of the toilet bowl, it is found that the urine reliably passes through the infrared detection region (2). Further, by dividing the detection region, even a small urine flow can be reliably detected.

Description

Cleaning toilet seat system
Technical Field
The present invention relates to a toilet seat system for washing a part of a human body in a toilet.
Background
Conventionally, such a toilet seat having a function of washing a part of a human body is configured as shown in fig. 10. The following describes the structure thereof with reference to the drawings.
As shown in fig. 10, the conventional wash toilet has a toilet seat 510 mounted to a toilet stool, a wash nozzle outlet 520, and a control unit 530. The conventional toilet seat has an internal structure including a washing nozzle, a driving unit, and a control unit 530, and the driving of the washing nozzle and the washing water sprayed from the nozzle can be adjusted by using the control unit 530 according to the preference of a user. With this configuration, the conventional toilet seat can be partially cleaned after defecation.
In recent years, it has been desired to add various functions to a toilet seat in addition to a washing function. For example, there are the following washing toilet seats: a microwave transmitting and receiving unit is provided on the front surface of the toilet seat, and detects the flow rate of urine by detecting the reflection state of the transmitted microwaves. As an example of such a toilet seat, there is provided: a microwave reflection information measuring unit for measuring reflected wave information of reflected waves reflected by emitting microwaves toward the urine flow excreted by the user; and a urine flow rate calculation unit that calculates a moving speed and a cross-sectional area of a urine droplet constituting a urine flow excreted by a user from the reflected wave information, and calculates a urine flow rate that is a urine flow rate per unit time (see, for example, patent document 1 (japanese patent application laid-open No. 2010-223772)).
With this configuration, when a person sitting on a toilet seat defecates, the urine flow can be detected to estimate the urine volume.
However, in the above-described conventional configuration, the microwave transceiver needs to be installed on the front surface of the toilet seat, and the urine flow is directly measured, which causes a problem of poor installation and maintenance.
Further, since the detection is performed by the microwave, there is a problem that water from the washing nozzle is detected in addition to the urine flow.
Further, stool is detected similarly to urine, and there is a problem that it is not easy to distinguish.
Disclosure of Invention
The toilet seat cleaning system according to an example of the present invention solves the above-described problems of the conventional toilet seat cleaning system, and an infrared sensor as an example of a urine detection unit is provided at the rear portion of the toilet seat, and the space inside the toilet seat becomes a detection area of the urine detection unit. According to this structure, both the urine flow in the air inside the toilet bowl and the urine flow on the toilet bowl can be detected similarly. Further, the urine flow can be detected accurately and efficiently without detecting the washing water ejected from the washing nozzle. Further, the presence or absence of urine, urination time, and urination pattern can be detected.
Specifically, an example of the toilet seat cleaning system according to the present invention includes: a toilet seat; a human body detection unit that detects a human body; a urine detection unit that detects urine excreted from the human body in real time in a non-contact manner; and a control unit that calculates the presence or absence of urination and the number of urination times based on the signal from the human body detection unit and the signal from the urine detection unit.
Preferably, the urine detection unit of the toilet seat cleaning system according to an example of the present invention is provided at the rear of the toilet seat. In the urine detection unit of the toilet seat washing system according to the embodiment of the present invention, the space inside the toilet bowl is preferably a detection area of the urine detection unit.
According to this configuration, the infrared sensor is provided at the rear portion of the toilet seat, and the infrared sensor and the toilet seat are integrated, so that the maintainability of the toilet seat cleaning system having the urine detection unit can be improved. In the toilet seat cleaning system according to the example of the present invention, since the space inside the toilet bowl is a detection area of the urine detection means, both the urine flow in the air inside the toilet bowl and the urine flow flowing over the toilet bowl can be detected similarly. Further, the flow of urine can be detected more reliably and efficiently without detecting the washing water ejected from the washing nozzle. Further, by detecting the presence or absence of urine, the urination time, and the urination pattern by using various detection means such as a human body detection means, a sitting seat detection means, and a urine detection means until the user comes out of the toilet, the accuracy and reliability of urine detection can be improved.

The toilet seat cleaning system according to an example of the present invention is provided with the infrared sensor at the rear of the toilet seat, and the infrared sensor and the toilet seat are integrated, thereby improving the maintainability of the toilet seat cleaning system having the urine detection unit. In the toilet seat cleaning system according to the embodiment of the present invention, since the space inside the toilet bowl is a detection area of the urine detection unit, both the urine flow in the air inside the toilet bowl and the urine flow flowing over the toilet bowl can be detected similarly. Further, the flow of urine can be detected accurately and efficiently without detecting the washing water ejected from the washing nozzle. Further, by detecting that the user is seated until standing by using various detection means such as the human body detection means, the seated position detection means, and the urine detection means, the presence or absence of urine, the urination time, and the urination pattern can be detected, and the accuracy and reliability of urine detection can be reliably improved.
In the toilet seat cleaning system according to an example of the present invention, the urine detection unit is constituted by an infrared sensor or an ultrasonic sensor provided in the vicinity of the cleaning nozzle of the toilet seat. Further, the detection region of the urine detection unit is set to a region in which urine can be detected in a non-contact manner before the urine falls down into the remaining water of the toilet bowl.
According to this configuration, the urine detection unit (for example, the non-contact urine detection sensor) and the toilet seat are integrated, and therefore, maintainability and installability can be improved. In the toilet seat cleaning system according to the embodiment of the present invention, since the space inside the toilet bowl is a detection area of the urine detection unit, both the urine flow in the air inside the toilet bowl and the urine flow flowing over the toilet bowl can be detected similarly. In addition, can not detect the inside retaining water of toilet bowl, can accurately and detect the urine and flow high-efficiently.

Embodiments of the present invention will be described below with reference to the drawings.
(embodiment mode 1)
A toilet seat cleaning system 100 according to embodiment 1 of the present invention will be described with reference to the drawings. Fig. 1 is a schematic view of a toilet seat cleaning system 100 according to embodiment 1 of the present invention. Fig. 2 is a schematic diagram of the toilet seat cleaning system 100 according to embodiment 1 of the present invention as viewed from the side. Fig. 3 is a schematic diagram showing an infrared detection area of the toilet seat cleaning system 100 according to embodiment 1 of the present invention. Next, the configuration of the toilet seat cleaning system 100 according to the present embodiment will be described.
As shown in fig. 1, a clean toilet seat system 100 according to embodiment 1 of the present invention includes a toilet seat 10 on which a user sits, and an infrared detection unit 1 as an example of a urine detection unit for detecting urine. Fig. 1 and 2 show an infrared detection area 2 as a detection area of an infrared detection unit 1 as an example of a urine detection unit. Fig. 2 shows a trajectory 3 of urine drop when the user stands in front of the toilet seat 10 and urinates. The infrared detection area 2 is designed such that the fallen urine 3 reliably passes through the infrared detection area 2 and is detected by the infrared detection unit 1. Further, since urine with a user seated on the toilet seat 10 flows along the surface of the toilet seat provided with the toilet seat 10, the infrared detection area 2 is designed such that such urine is reliably detected by the infrared detection unit 1 through the infrared detection area 2 as well. Since the temperature of urine is about 38 ℃, even if the temperature of washing water is about 30 ℃, urine and washing water can be detected by reliably distinguishing them by the infrared detection unit 1. Further, as shown in fig. 3, by dividing the detection region (in the present embodiment, the infrared detection region 2) of the urine detection means, urine can be reliably detected even with a small urine flow. Further, by providing a plurality of infrared detection units 1 in the toilet seat washing system 100, the non-detection region can be eliminated, and the urine flow can be detected more reliably.
When a person enters a toilet and urinates in a standing state, as shown in fig. 2, a path 3 of urine is a path from above the toilet seat cleaning system 100 toward the inside of the toilet bowl provided with the toilet seat 10. In this case, according to the toilet seat washing system 100 of the present embodiment, urine reliably passes through the infrared detection area 2, and it is determined by the infrared detection unit 1 that the urine flow is. In addition, when the toilet seat washing system 100 is provided with the human body detecting means and the sitting seat detecting means, the urination time and the urination pattern can be obtained based on signals from the human body detecting means and the sitting seat detecting means.
In the present embodiment, as shown in fig. 1 and 2, an infrared sensor as an example of the infrared detection unit 1 is provided at the rear portion of the toilet seat 10, and the infrared sensor and the toilet seat 10 are integrated. With this configuration, the maintainability of the toilet seat cleaning system 100 having the urine detection unit can be improved. Further, the toilet seat washing system 100 of the present embodiment is designed such that the space inside the toilet seat where the toilet seat 10 is provided becomes the detection area of the urine detection unit. According to this structure, both the urine flow in the air inside the toilet bowl and the urine flow flowing over the toilet bowl can be detected similarly. Further, the urine flow can be detected accurately and efficiently without detecting the washing water ejected from the washing nozzle by the urine detection unit. Further, by detecting the presence or absence of urine, the urination time, and the urination pattern by detecting the user's entry into the toilet room using various detection units of the toilet seat washing system 100, the accuracy and reliability of urine detection can be reliably improved.
The infrared sensor of the infrared detection unit 1, which is an example of the urine detection unit in the present embodiment, may be a far infrared sensor for detecting temperature, or may be a non-contact object detection sensor such as an ultrasonic sensor.
As in the toilet seat washing system 100 according to the present embodiment, by using a non-contact urine detection sensor such as an infrared sensor as the infrared detection unit 1 which is an example of the urine detection unit and integrating the urine detection unit and the toilet seat 10, the maintainability and installability of the urine detection unit can be improved. In addition, the toilet seat cleaning system 100 is configured such that the space inside the toilet seat where the toilet seat 10 is provided becomes the detection area of the urine detection means, and thus both the urine flow in the air inside the toilet seat and the urine flow flowing over the toilet seat can be detected similarly. Further, according to the configuration of the toilet seat cleaning system 100 of the present embodiment, the remaining water in the toilet bowl is not detected by the urine detection unit, the urine flow can be accurately and efficiently detected, and the accuracy and reliability of the urine detection can be reliably improved.
Next, the operation of the toilet seat cleaning system 100 according to the present embodiment will be described with reference to the drawings. Fig. 4 is a flowchart showing a process procedure when the toilet seat cleaning system 100 according to embodiment 1 of the present invention is used.
In the present embodiment, an infrared sensor as the infrared detection unit 1 which is an example of the urine detection unit is provided below the rear portion of the toilet seat 10 of the toilet seat cleaning system 100, and the infrared sensor and the toilet seat are integrated. Further, the detection area of the infrared sensor is designed to be located inside the toilet bowl and above the water storage portion of the toilet bowl. The detection area of the infrared sensor is designed not to detect a human body seated on the toilet seat. In the present embodiment, a human body detection sensor as a human body detection means for detecting that a person enters a toilet room is provided in the toilet room or in a component (the toilet seat 10, the toilet bowl, the lid, or the like) constituting the toilet seat system 100 separately from the infrared sensor.
Next, a flow when the toilet seat cleaning system 100 according to the present embodiment is used will be described. First, when a person enters a toilet (step S0), the person is detected by a human body detection sensor provided in the toilet (step S1), and a room signal is turned on (step S2). When a person who enters a toilet starts urination while standing (step S3), urine is detected by an infrared sensor provided at the lower part of the toilet seat 10 because the temperature of urine is higher than the ambient temperature (step S4). When urination is completed (step S5) and a person comes out of the toilet (step S6), the absence of a person is determined by a human body detection sensor in the toilet (step S7), and the room signal is turned off (step S8). According to this flow, the urination pattern can be obtained based on the urination information such as the number of times the user enters the toilet, the number of times urination has been performed, the actual presence or absence of urination, the actual time of urination, and the room time. The information obtained by the toilet seat cleaning system 100 can be transmitted to a cloud server capable of communicating with the toilet seat cleaning system 100 by wireless transmission or the like, and stored in a data server.
In this way, the toilet seat cleaning system 100 according to the present embodiment is provided with an infrared sensor as an example of a urine detection unit at the rear portion of the toilet seat 10, and the infrared sensor is integrated with the toilet seat 10. With this configuration, the maintainability of the urine detection unit can be improved. In the toilet seat cleaning system 100 according to the present embodiment, the space inside the toilet seat where the toilet seat 10 is installed is configured to be a detection area of the urine detection unit. According to this structure, both the urine flow in the air inside the toilet bowl and the urine flow flowing over the toilet bowl can be detected similarly. Further, according to the configuration of the toilet seat system 100 of the present embodiment, the urine flow can be accurately and efficiently detected without detecting the washing water ejected from the washing nozzle. In addition, in the case where the toilet seat system 100 includes the human body detection unit and the sitting detection unit, the presence or absence of urine, the urination time, and the urination pattern can be detected by detecting the presence or absence of a user entering the toilet room by the human body detection unit and the sitting detection unit, and the accuracy and reliability of urine detection can be reliably improved.
Fig. 5 shows a relationship between sensor output and time obtained from the toilet seat cleaning system 100 according to embodiment 1 of the present invention. When a person enters a toilet, a human body detection sensor, which is an example of human body detection means, is turned on. When a person who enters a toilet starts urination, an infrared sensor, which is an example of urine detection means, is turned on, and the start and end of urination and the urination state can be detected. The total time of turning on of the infrared sensor can be defined as the actual urination time. The urine volume can be estimated from the urination time.
According to the present embodiment, the time from the start of urination to the end of urination of a person entering a toilet can be detected, and the urine volume can be estimated from the integrated value of the time at which urination is detected. Further, the presence or absence of urine, urination time, urination amount, urination frequency, and urination pattern can be detected, and the accuracy and reliability of urine detection can be reliably improved.
The toilet seat cleaning system 100 of the present embodiment is provided with an infrared sensor as an example of urine detection means at the rear portion of the toilet seat 10, and the infrared sensor and the toilet seat are integrated. With this configuration, the maintainability of the urine detection unit can be improved. In the toilet seat cleaning system 100 according to the present embodiment, the space inside the toilet bowl is set as the detection area of the urine detection unit. According to this structure, both the urine flow in the air inside the toilet bowl and the urine flow flowing over the toilet bowl can be detected similarly. Further, the flow of urine can be detected accurately and efficiently without detecting the washing water ejected from the washing nozzle. Further, the presence or absence of urine, the urination time, the urination frequency, and the urination pattern can be detected by detecting that the user has entered the toilet by using various detection units of the toilet seat washing system 100. Further, by detecting the integrated value of the urination time by the toilet seat cleaning system 100 according to the present embodiment, the urine volume can be estimated, and the accuracy and reliability of the urine detection can be reliably improved.
Fig. 6 is a graph showing the relationship between the number of urine insults and the number of urine insults displayed by the portable information terminal 4 according to embodiment 1 of the present invention. The urination pattern can be obtained from urination information such as the number of times of entering the toilet, the number of times of urination, the actual presence or absence of urination, the actual time of urination, and the toilet room time by using various detection means such as a human body detection means, a sitting seat detection means, and a urine detection means of the toilet seat system 100. These pieces of information can be transmitted from the toilet seat cleaning system 100 to the cloud server by wireless transmission or the like, and stored in the data server. Further, as shown in fig. 6, these pieces of information can be displayed on the portable information terminal 4, and the urination information of each individual can be checked and confirmed collectively.
That is, although the number of times of entering the toilet changes as usual, a decrease in the number of times of urination indicates that no urine is discharged even when entering the toilet. The user and the relevant person can be immediately informed of the signs of the physical changes, and early detection of diseases can be achieved.
In this way, by providing an infrared sensor as an example of the urine detection unit at the rear portion of the toilet seat 10 and integrating the infrared sensor and the toilet seat, the maintainability of the urine detection unit can be improved. Further, the toilet seat washing system 100 is configured such that the space inside the toilet bowl becomes the detection area of the urine detection unit, and thus both the urine flow in the air inside the toilet bowl and the urine flow flowing over the toilet bowl can be detected similarly. Further, the flow of urine can be detected accurately and efficiently without detecting the washing water ejected from the washing nozzle. Further, by detecting the presence or absence of urine, the urination time, and the urination pattern by detecting the user's entry into the toilet room using various detection units of the toilet seat washing system 100, the accuracy and reliability of urine detection can be reliably improved.
The washing toilet seat system 100 of the present invention can be applied to a washing toilet seat for use in nursing or hospital facilities, and can also be applied to a washing toilet seat having a drying unit.
(embodiment mode 2)
Next, a toilet seat cleaning system 100 according to embodiment 2 of the present invention will be described with reference to the drawings.
Fig. 7 is a flowchart showing a process procedure when the toilet seat cleaning system 100 according to embodiment 2 of the present invention is used. Next, a flow when the toilet seat cleaning system 100 according to the present embodiment is used will be described.
In the toilet seat cleaning system 100 according to the present embodiment, an infrared sensor as an example of urine detection means is provided below the rear portion of the toilet seat 10, and the infrared sensor is integrated with the toilet seat 10. The detection area of the infrared sensor, which is an example of the urine detection means, is set inside the toilet bowl and above the water storage unit. The detection area of the infrared sensor is set so as not to detect a human body seated on the toilet seat 10. In the present embodiment, a human body detection sensor, which is an example of human body detection means for detecting entry of a human body into a toilet, is provided in the toilet or a component constituting the toilet seat cleaning system 100, separately from the infrared sensor. In the present embodiment, a seating sensor is provided as an example of seating detection means for detecting that a person who enters a toilet sits on the toilet seat 10.
First, when a person enters a toilet (step S0), the person is detected by a human body detection sensor provided in the toilet (step S1), and a room signal is turned on (step S2). When a person who enters a toilet sits on the toilet seat (step S13), a sitting signal is turned on (step S14). When a person who enters a toilet starts urination (step S15), the temperature of urine is higher than the ambient temperature, and therefore, the infrared sensor provided at the lower portion of the toilet seat 10 detects the urine (step S16). When urination is finished (step S17) and the person stands up from the toilet seat (step S18), the seating signal is turned off (step S19). When a person comes out of the toilet (step S6), it is determined by the human body detection sensor in the toilet that no person is present (step S7), and the room signal is turned off (step S8). According to this flow, the urination pattern can be obtained based on the urination information such as the number of times of entering the toilet, the number of times of sitting, the number of times of urination, the actual presence or absence of urination, the actual time of the urination, the sitting time, and the room time. The information may be transmitted directly or indirectly from the toilet seat washing system 100 to the cloud server by wireless transmission or the like, and stored in the data server.
The toilet seat cleaning system 100 according to the present embodiment is provided with an infrared sensor as an example of urine detection means at the rear portion of the toilet seat 10, and integrates the infrared sensor and the toilet seat. With this configuration, the maintainability of the urine detection unit can be improved. In the toilet seat cleaning system 100 according to the present embodiment, the space inside the toilet bowl is a detection area of the urine detection unit. According to this structure, both the urine flow in the air inside the toilet bowl and the urine flow flowing over the toilet bowl can be detected similarly. Further, the flow of urine can be detected accurately and efficiently without detecting the washing water ejected from the washing nozzle. Further, by detecting that the user is seated until standing by using various detection means such as the human body detection means, the seated position detection means, and the urine detection means, the presence or absence of urine, the urination time, the seated position time, and the urination pattern can be detected, and the accuracy and reliability of urine detection can be reliably improved.
Further, the urination information obtained by the toilet seat cleaning system 100 is directly or indirectly transmitted from the toilet seat cleaning system 100 to the cloud server using a network connection, thereby enabling the user to know the daily change of the urination information. For example, by using a WiFi connection, the urination information obtained by washing the toilet seat system 100 can be transmitted to and displayed on a portable information terminal such as a mobile phone or a smart phone.
Fig. 8 is a graph showing a relationship between sensor output and time obtained from the toilet seat cleaning system 100 according to embodiment 2 of the present invention. When a person enters a toilet, the human body detection sensor is turned on, then when the person entering the toilet sits on the toilet seat, the sitting sensor is turned on, and when urination is started, the urine detection sensor, which is an infrared sensor, is turned on, and a urination state can be detected. The total time (integrated value) during which the infrared sensor is turned on can be defined as the actual urination time. The urine volume can be estimated from the urination time.
According to the toilet seat cleaning system 100 of the present embodiment, it is possible to detect the time from when a person enters a toilet and sits down, starts urination, and ends urination, and estimate the urine volume from the integrated value of the detected urination time. Further, the presence or absence of urine, urination time, urination amount, urination frequency, and urination pattern can be detected, and the accuracy and reliability of urine detection can be reliably improved.
Fig. 9 is a graph showing a relationship between sensor output time and urine volume obtained from the toilet seat cleaning system 100 according to embodiment 2 of the present invention. As shown in fig. 9, even with the same urine volume, the total on time of the infrared sensor (the cumulative time of the on time of the infrared sensor) differs because the flow pattern of urine differs between the case where there is a seating sensor output (the seating sensor output is on) and the case where there is no seating sensor output (the seating sensor output is off). When the user performs urination while standing without sitting on the toilet seat 10, the urine immediately falls into the remaining water in the air inside the toilet, and therefore the total on time of the infrared sensor is short. On the other hand, when the user urinates in a seated state on the toilet seat 10, the total on time of the infrared sensor is long because the urine flows on the surface of the toilet seat and reaches the remaining water. In the toilet seat cleaning system 100 according to the present embodiment, the estimation formula used for estimating the urine volume is switched according to the difference in the output of the seating sensor (the difference in the total on time). With this configuration, the urine volume can be estimated more accurately.
The toilet seat cleaning system 100 of the present embodiment detects the time from when a person enters a toilet, when urination starts, to when urination ends, by using the urine detection unit. The flow of the urine flow is determined according to whether or not the person is seated on the toilet seat 10, and the estimation formula used for estimating the amount of urine is changed according to the difference in the output of the seating detection means. With this configuration, the urine volume can be estimated from the integrated value of the on time of the urine detection signal, the presence or absence of urine, the urination time, the urination volume, and the urination pattern can be detected, and the accuracy and reliability of urine detection can be reliably improved.
The toilet seat cleaning system 100 according to the present embodiment is configured such that an infrared sensor as an example of a urine detection unit is provided at the rear portion of the toilet seat 10, and the space inside the toilet seat becomes a detection area of the urine detection unit. According to this structure, both the urine flow in the air inside the toilet bowl and the urine flow flowing over the toilet bowl can be detected similarly. Further, the urine flow can be detected accurately and efficiently without detecting the washing water ejected from the washing nozzle. Further, by detecting the presence or absence of urine, urination time, urination amount, urination frequency, room time, sitting frequency, sitting time, and urination pattern by detecting the user's entry into the toilet by various detection means such as a human body detection means, a sitting detection means, and a urine detection means. Further, according to the toilet seat cleaning system 100 of the present embodiment, it is possible to observe the information obtained by the toilet seat cleaning system 100 by using the portable information terminal, and it is possible to reliably improve the accuracy and reliability of urine detection.
In the present embodiment, an infrared sensor is used as a urine detection sensor that is an example of the urine detection means, but an ultrasonic sensor or a light beam sensor may be used.
The control method according to the control of the toilet seat cleaning system 100 according to embodiment 1 and embodiment 2 of the present invention is executed by a computer-readable program in which a program for executing the steps described above by using a computer or the like having a CPU (Central Processing Unit) is recorded. Each of the steps described in embodiment 1 and embodiment 2 of the present invention can be executed by a program cooperating with hardware resources such as an electric device, an information device, a computer, and a server, which include a CPU (or a microcomputer), a RAM (Random Access Memory), a ROM (Read Only Memory), a storage device or a recording device, and an I/O (Input/Output). The program used in the toilet seat cleaning system 100 according to the present invention may be recorded in a recording medium such as a magnetic medium or an optical medium, or may be distributed using a communication line such as the internet. According to the program used in the toilet seat cleaning system 100 of the present invention, it is possible to easily perform the distribution, update, and installation work of the program for realizing the new function of the toilet seat cleaning system 100.
As described above, in the toilet seat cleaning system 100 according to the present invention, the toilet seat 10 and the non-contact sensor, which is an example of the urine detection unit, are integrated. Further, the toilet seat washing system 100 according to the present invention can detect urine by the non-contact sensor of the urine detection unit, and detect the presence, number, time, and urination pattern of urination based on the detection results of the human body detection unit and the sitting seat detection unit and the detection result of the non-contact sensor. Further, by directly or indirectly transmitting urination information including the detection results from the toilet seat washing system 100 to the server by wireless or the like, urination detection can be efficiently performed, and the urination pattern can be easily and accurately determined.
According to the present invention, a small and simple toilet seat cleaning system can be provided, and the accuracy and reliability of urine detection can be reliably improved.
