Description

  The present invention relates to a toilet cleaning device that performs toilet cleaning by detecting a user's operation and operation state with a sensor.

2. Description of the Related Art Conventionally, a toilet cleaning device that detects a toilet user with a sensor and automatically or manually cleans the toilet is known.
As a means for performing toilet cleaning automatically, it is conceivable to provide a human body detection sensor on the toilet body or the like. Specifically, after detecting that the user has approached or sat down on the toilet bowl for a predetermined time or more, toilet cleaning can be performed when it is detected that the user has left or separated from the toilet bowl.
Further, as a means for manually performing toilet cleaning, it is conceivable to provide a remote controller at a position where the user can easily operate. Specifically, when the user operates the remote controller, the operation information is transmitted to the main body side, and toilet flushing can be performed. In view of hygiene, it is desirable that the remote control can be operated without contact, and for that purpose, it is preferable to use a sensor.

Furthermore, when cleaning a toilet bowl or the like, it is also desired to forcibly prohibit the automatic cleaning operation temporarily, and a technique such as Patent Document 1 is known.
In the technique of Patent Document 1, the operation mode is changed depending on the sensing states of the first sensor means and the second sensor means, each having a different sensing area.
Specifically, automatic cleaning is performed when the sensing state of the first sensor unit continues for a predetermined time or more and then the non-sensing state is performed, and manual cleaning is performed when the first sensor unit and the second sensor unit are simultaneously sensing. If the first sensor means is in a non-sensing state and the second sensor means is in a sensing state, automatic cleaning is prohibited.
In this way, three cleaning modes of automatic cleaning, manual cleaning, and automatic cleaning prohibition can be operated with two sets of sensors.
JP2002-106022

However, in the technique of Patent Document 1, a user's operation is necessarily required to enter the automatic cleaning prohibition mode.
Further, in order to sense only the second sensor, an operation such as holding a hand at a predetermined position is required after the sensing area is grasped. When installed at home, the user is only a resident, so it can be understood that the automatic cleaning prohibition mode function is provided, and the operation method can be learned every time it is used several times. There is no effect on usability.
However, when it is installed in the public, since there are an unspecified number of users, it is difficult to make it well known that it has the function of the automatic cleaning prohibition mode, and it is difficult to understand the operation method.
This invention is made | formed in view of the said subject, and is providing the toilet bowl washing | cleaning apparatus which can be put into automatic washing | cleaning prohibition mode automatically, without a user performing special operation.

In order to achieve the above object, according to the first aspect of the present invention,
A remote control determination means for transmitting a propagation wave and determining the presence state of the user based on the reflection level; a transmission means for transmitting determination information of the remote control determination means;
A remote control device comprising: a toilet flushing means for driving an electromagnetic valve for supplying flush water to the toilet; a main body detection means for detecting seating of a user; and reception for receiving the determination information from the transmission means Means,
A main body device having a main body control unit for driving the toilet bowl cleaning means to perform toilet cleaning based on the detection result of the main body detection means and the determination information, The main body control unit includes an automatic cleaning mode in which the main body detection unit performs toilet cleaning when the seating detection state is continued after the seating detection state for a predetermined time or longer and the body detection unit is in the seating detection state. An automatic cleaning prohibiting mode for stopping the automatic cleaning mode based on the determination information from the remote control determination unit is provided.

  This eliminates the need for the user to operate the main body or the remote control to enter the automatic cleaning prohibition mode. In addition, since the automatic cleaning prohibition mode is automatically entered by combining the detection statuses of the sensor of the main body and the sensor of the remote controller, the user does not need to perform any special operation.

  According to a second aspect of the present invention, when the reflection level is less than a first threshold value, the remote control determination unit determines that the user does not exist in the vicinity of the toilet, and the reflection When the level is greater than or equal to the first threshold, it is determined that the user is seated on the toilet and the reflection level is greater than or equal to the second threshold greater than the first threshold. When it is determined that the user is present in front of the toilet, and the reflection level is equal to or greater than a third threshold value that is greater than the second threshold value, the user is directed toward the remote control device. When it is determined that the hand-holding operation is being performed, and the main body control unit determines that the user does not exist near the toilet when the main body detection unit is in the seating detection state, Alternatively, the main body detection means is in a seating detection state. There are, the remote control determining means, when it is determined that the user prior to said toilet bowl is present, when one is satisfied, the wherein the stopping the automatic cleaning mode.

  As a result, the user can discriminate the operation different from the time of stool, for example, the operation such as cleaning, by the combination of the detection status of the sensor of the main body and the sensor of the remote control, and the user can perform a special operation. The automatic cleaning mode can be stopped without performing.

Further, the main body control unit 20 includes main body detection means 22 for determining whether a person is sitting on or away from the toilet 42. The light projecting element 31 of the light projecting / receiving unit 30 transmits infrared light as a propagation wave, and the light is reflected by the back of the user seated on the toilet 42 and the light receiving element 32 receives the reflected light. The main body detecting means 22 compares the reflection level received by the light receiving element 32 of the light projecting / receiving unit 30 with a preset threshold value, and determines that there is an object if it is equal to or higher than the threshold value. If it is less than the value, it is determined that there is no object, and the detection result is output as an electric signal to the toilet cleaning means 23 through the wiring.
The toilet flushing means 23 controls the driving of the electromagnetic valve 40 in accordance with the detection result received from the main body detection means 22, and supplies flush water from the water supply source 41 to the toilet 42 through the water passage 43.

In addition, the main body control unit 20 includes a receiving unit 21 that receives a radio signal from a remote controller 60 provided on the wall. The receiving means 21 outputs the result of receiving the radio signal as an electric signal to the toilet cleaning means 23 through the wiring.
The toilet flushing means 23 controls the driving of the electromagnetic valve 40 based on the reception result received from the receiving means 21, and supplies flush water from the water supply source 41 to the toilet 42 through the water passage 43.

FIG. 3 is a block diagram illustrating a remote control according to the embodiment.
The remote controller 60 according to the present embodiment includes a light projecting / receiving unit 80 that a user holds over to wash the toilet bowl. The light projecting element 81 included in the light projecting / receiving unit 80 transmits infrared light as a propagation wave, and the light is reflected by a finger or the like held by the user, and the light receiving element 82 receives the reflected light. The remote control determination unit 72 compares the reflection level received by the light receiving element 82 of the light projecting / receiving unit 80 with a plurality of preset threshold values to determine the operation status of the user. The determination result is output as an electrical signal to the transmission means 71 through the wiring.
The transmission means 71 transmits the determination result as a radio signal to the reception means 21 included in the toilet bowl cleaning device 10 described above.
Further, a battery 90 which is a driving power source of the remote controller 60 is provided.

The remote control determination unit 72 and the transmission unit 71 are provided in the remote control unit 70. The remote control unit 70 can be constituted by a microprocessor, a memory, a program for operating these, and the like (not shown above). The operation of the remote controller 60 is controlled.
Note that the drive power of the remote controller 60 may be supplied from a commercial power supply, not from a battery, or from the toilet bowl cleaning device 10.
The communication medium between the receiving unit 21 and the transmitting unit 71 may be wired instead of wireless.

Hereinafter, the detection mode of the light projecting / receiving unit provided in the present embodiment will be described with reference to the drawings.
FIG. 4 is a schematic view illustrating the detection state of the light projecting / receiving unit on the main body side according to this embodiment.
A detection area 100 represents a detection area of the light projecting / receiving unit 30 on the main body side.
First, during a period when the user is not present near the toilet 42, the reflection level of the light projecting / receiving unit 30 of the main body is low, and the main body control unit 20 determines that it is not detected (period T10).
Subsequently, the reflection level gradually increases as the user approaches the toilet 42, but the main body control unit 20 continues the non-detection determination in a state of less than the threshold value L10 (period T11).
Further, when the user approaches the toilet 42, the reflection level becomes equal to or higher than the threshold value L10, and the main body control unit 20 determines that the user has reached the toilet (period T12).
Thereafter, when the user sits on the toilet 42, the reflection level becomes equal to or higher than the threshold value L12, and the main body control unit 20 determines that the user is seated (period T13).
In the present embodiment, the non-detected state and the state where the user is in front of the toilet are collectively referred to as a separated state.

FIG. 5 is a schematic view illustrating the detection mode of the light projecting / receiving unit on the remote control side according to the present embodiment.
The detection area 110 represents the detection area of the light projecting / receiving unit 80 on the remote control side.
First, during a period when the user is not in the vicinity of the toilet 42, the reflection level of the light projecting / receiving unit 80 of the remote controller is small and becomes less than the threshold value L20, and the remote controller control unit 70 determines that it is not detected (period T20).
Subsequently, when the user approaches the toilet 42, the reflection level gradually increases, and when the user reaches the threshold L21 or more, the remote control unit 70 determines that the user has reached the toilet ( Period T21).
Thereafter, when the user sits on the toilet 42, the reflection level falls below the threshold L21, but the reflection level becomes higher than that in the non-detection state. More specifically, it is between the threshold value L20 and less than the threshold value L21 (period T22).

Then, when the user holds his / her finger over the remote controller 60 in the sitting state, the reflection level becomes the highest, and the state becomes equal to or higher than the threshold value L22. In this state, remote control unit 70 determines that the user is holding the hand (period T23).
Since the remote controller 60 is used in a state where the user is seated, it is preferable that the installation location is the horizontal wall of the front portion of the toilet 42. Therefore, the reflection level of the light projecting / receiving unit 80 is higher when standing in front of the toilet than when sitting. Further, when the hand is held up, the light projecting / receiving unit 80 is covered with fingers in the vicinity, so that the reflection level becomes the highest.

Hereinafter, a specific cleaning operation of the present embodiment will be described with reference to FIGS.
FIG. 6 is a timing chart showing a manual cleaning operation and a first automatic cleaning operation of the toilet bowl cleaning apparatus according to the present embodiment.
When the user reaches the front of the toilet, the reflection level of the light projecting / receiving unit 30 on the main body side is maintained below the threshold value L12, and the reflection level of the light projecting / receiving unit 80 on the remote control side is the threshold value L21 and the threshold value L22. (Time t30). Thereafter, when the user is seated, the reflection level of the light projecting / receiving unit 30 on the main body side becomes equal to or higher than the threshold value L12, and the reflection level of the light emitting / receiving unit 80 on the remote control side is between the threshold value L20 and the threshold value L21 ( Period T31).

When the user holds his / her finger over the remote controller 60, the reflection level of the light projecting / receiving unit 80 on the remote controller side becomes equal to or higher than the threshold value L22, and toilet flushing is executed at this timing (time t32). Since the cleaning operation is performed by holding a finger over the remote controller, this cleaning operation is called a manual cleaning mode.
Thereafter, when the user leaves and leaves the toilet, washing is performed (time t33). Since the cleaning operation is automatically performed when the user leaves the seat, this cleaning operation is called an automatic cleaning mode.

FIG. 7 is a timing chart showing a second automatic cleaning operation of the toilet bowl cleaning device according to the present embodiment.
The operation until the user reaches the toilet is the same as that shown in FIG. 6 (time t30). After that, the user continues standing in front of the toilet without sitting down. This represents the action of a man adding urine. Since it is not seated, the reflection level of the light projecting / receiving unit 30 on the main body side continues between the threshold value L10 and the threshold value L12, and the reflection level of the light projecting / receiving unit 80 on the remote control side is the threshold value L21. And the threshold value L22 (period T51). When the user leaves after the toilet, toilet cleaning is performed at this timing (time t52). Since toilet cleaning is automatically performed when the user leaves, this cleaning operation also becomes an automatic cleaning mode.

FIG. 8 is a timing chart showing a first automatic cleaning prohibiting operation of the toilet bowl cleaning device according to the present embodiment.
As a premise, in this timing chart, it is assumed that the user approaches the toilet bowl 42 in order to clean the toilet bowl.
The operation until the user reaches the toilet is the same as that shown in FIG. 6 (time t30). Thereafter, the user moves around the toilet bowl to clean the toilet bowl 42. For example, when the side surface of the toilet bowl 42 is polished with a rag or the like, the reflection level of the light projecting / receiving unit 30 on the main body side is changed from the state before the toilet bowl to the seated state, and thereafter the seated state is maintained (period T62). On the other hand, the reflection level of the light projecting / receiving unit 80 on the remote control side changes from the state in front of the toilet to the non-detection state, and thereafter maintains the non-detection state (period T62). This means that when the side surface of the toilet 42 is being cleaned, the user is sitting on the side of the toilet 42, and the light projecting / receiving unit 30 on the main body side and the user's body are kept in an approaching state, This is because the light emitting / receiving unit 80 on the remote control side is out of the detection area 110.

Thereafter, after finishing the side surface of the toilet 42, the reflection level of the light projecting / receiving unit 30 on the main body side returns to the front toilet state, and the reflection level of the light emitting / receiving unit 80 on the remote control side also returns to the front toilet state (after time t63). ). This shows that the user has finished cleaning and stands in front of the toilet. Then, the user leaves the toilet 42 as it is, but toilet cleaning by automatic cleaning is not performed (time t64). That is, automatic cleaning is prohibited, and this operation is called an automatic cleaning prohibition mode.
The condition for entering the automatic cleaning prohibition mode is determined in period T62. Specifically, while the reflection level of the light projecting / receiving unit 30 on the main body side is in the seating state, the reflection level of the light projecting / receiving unit 80 on the remote control side is This is when a non-detection state occurs.

FIG. 9 is a timing chart showing a second automatic cleaning prohibiting operation of the toilet bowl cleaning apparatus according to the present embodiment.
As a premise, in this timing chart, as in FIG. 8, it is assumed that the user approaches the toilet 42 in order to clean the toilet.
The operation until the user reaches the toilet is the same as that shown in FIG. 6 (time t30). Thereafter, the user moves around the toilet bowl to clean the toilet bowl 42. For example, when the toilet lid and toilet seat of the toilet bowl 42 are polished with a rag or the like, the reflection level of the light projecting / receiving unit 30 on the main body side is changed from the state before the toilet bowl to the seated state, and thereafter the seated state is maintained (period T72). . On the other hand, the reflection level of the light projecting / receiving unit 80 on the remote control side maintains the state before the toilet (period T72). This is because when the toilet lid or toilet seat of the toilet bowl 42 is being cleaned, the user leans forward with respect to the toilet bowl 42, while the light projecting / receiving unit 30 on the main body side and the user's body are maintained in an approaching state. This is because the distance relationship and the positional relationship between the light emitting / receiving unit 80 on the remote control side and the user's body are almost unchanged.

Thereafter, when the toilet lid and toilet seat of the toilet bowl 42 have been polished, the reflection level of the light projecting / receiving unit 30 on the main body side returns to the front toilet state, and the reflection level of the light projecting / receiving unit 80 on the remote control side maintains the front toilet state ( After time t73). Then, the user leaves the toilet 42 as it is, but the toilet cleaning by the automatic cleaning is not performed (time t74). That is, automatic cleaning is prohibited, and this operation is also in the automatic cleaning prohibition mode.
The condition for entering the automatic cleaning prohibition mode is determined in the period T72. Specifically, the reflection level of the light projecting / receiving unit 80 on the remote control side is set while the reflection level of the light projecting / receiving unit 30 on the main body side is seated. This is when there is no change from the state of the toilet bowl.

Subsequently, a specific processing flow of the present embodiment will be described below with reference to FIGS. 10 to 13. These processes are performed by the main body control unit 20.
FIG. 10 is a flowchart showing the overall flow of processing according to the present embodiment. First, in S1000, the manual cleaning mode, the automatic cleaning mode, the automatic cleaning prohibition mode, and which mode should be selected are determined. In S1001, a cleaning process is performed based on the cleaning mode determined in S1000 and the seating information determined by the main body detection means.

  FIG. 11 is a flowchart showing a process for determining a cleaning mode according to the embodiment (hereinafter referred to as a cleaning mode determination process). In S2000, it is determined whether or not the remote control determination means has confirmed the hand-holding detection. This is determined based on information received by the receiving means provided in the main body control unit from the remote controller. Further, this determination does not indicate whether or not the hand-holding detection state is set, but is a step for determining whether or not the hand-holding detection state is entered from a state where the hand-holding detection is not performed. When the hand-holding detection state is changed from the state where the hand-holding is not detected (Yes in S2000), S2009 is executed. In S2009, the current cleaning mode is temporarily stored in the buffer. This is for use in determination for returning to the original cleaning mode when the manual cleaning mode is released. The current cleaning mode refers to an automatic cleaning mode or an automatic cleaning prohibition mode. In step S2010, the current mode is set as the manual cleaning mode, and the cleaning mode determination process is terminated.

  When it is not in the hand-holding detection state from the state in which the hand-holding is not detected (No in S2000), S2001 is executed. In step S2001, it is determined whether the main body detection unit is detecting seating. When the main body detection means is not detecting seating (seated state) (No in S2001), the current cleaning mode is set to the automatic cleaning mode in S2002, and the cleaning mode determination process is terminated. This is because the automatic cleaning mode is set in the sitting state and the automatic cleaning prohibiting mode is set when a certain condition is satisfied in the sitting state.

  When the main body detection means is detecting seating in S2001 (Yes in S2001), it is determined in S2003 whether the remote control determination means is not detecting a human body. When the remote control determination means is not detecting a human body in S2003 (Yes in S2003), a timer is started in S2004 in order to time the determination that the remote control determination means is not detecting. When the remote control determination unit is not detecting the human body in S2003 (No in S2003), it is determined in S2011 whether the remote control determination unit is currently detecting the toilet front. When the remote control determination means is detecting in front of the toilet in S2011 (Yes in S2011), a timer is started in S2012 to measure the time that the remote control determination means determines that the detection in front of the toilet is in progress. When the toilet pre-detection is not being performed (No in S2011), the cleaning mode determination process is terminated. In other words, in S2003 and S2011, when the remote control determination means is not detecting the human body or detecting in front of the toilet, the time is counted, and when neither of them is applicable, a determination is made to end the washing mode determination process. Will be.

  After the timer is started in S2004, it is determined in S2005 whether the remote control determination unit is not detecting the human body. When the human body is not being detected (Yes in S2005), the processing of S2005 is continued. When the human body is not being detected (No in S2005), the timer is stopped in S2006. In S2007, the threshold A is compared with the time during which the human body is not detected, which is timed by the timer this time. The value of the threshold A is preferably set to a value sufficiently longer than the time during which the main body detection means is detecting seating and the remote control determination means is not detecting a human body during normal use. When the value measured by the timer is equal to or greater than the threshold value A (Yes in S2007), it is determined that a special operation that is not normal use is in progress (toilet bowl cleaning), and the current cleaning mode is set to the automatic cleaning prohibition mode in S2008. Set to. When the value measured by the timer is less than the threshold value A (No in S2007), the cleaning mode determination process is terminated. The processing from S2012 to S2015 is the same as the processing from S2004 to S2007, and the flow and concept are the same. The details of the detection determination in S2013 and the threshold value in S2015 are different, and the detailed description is omitted.

  FIG. 12 is a flowchart showing a process (hereinafter referred to as “cleaning confirmation process”) for confirming the cleaning based on the cleaning mode and the determination result of the main body detection unit according to this embodiment. In S3000, it is determined whether the current mode is the manual cleaning mode. When the current mode is the manual cleaning mode (Yes in S3000), the process proceeds to S3003. Since the manual cleaning mode ends in S3003, the mode stored in the buffer in S2009 of FIG. 11 is set to the current mode. The mode stored in the buffer means an automatic cleaning mode or an automatic cleaning prohibition mode. Subsequently, a cleaning process is performed in S3004, and the cleaning confirmation process is terminated. The washing process refers to supplying washing water from the water supply source to the toilet through a water passage by controlling the driving of the electromagnetic valve for a predetermined time.

  When the current mode is not in the manual mode in S3000 (No in S3000), it is determined in S3001 whether the main body detection means has detected the separated state from the seated state. When the main body detection means does not detect the separated state from the seated state (No in S3001), the cleaning confirmation process is terminated. When the main body detection means detects the separated state from the seated state (Yes in S3001), the current cleaning mode is determined in S3002. When the current cleaning mode is the automatic cleaning mode (Yes in S3002), it means that the separated state has been detected from the seating state of the user, so the process proceeds to the cleaning process of S3004 to perform automatic cleaning. When the current cleaning mode is not the automatic cleaning mode, in other words, when the automatic cleaning prohibition mode is set (No in S3002), the sitting state is detected from the sitting state, but it is determined that it is not normally used (during toilet cleaning). Therefore, the automatic cleaning is canceled, that is, the cleaning confirmation processing is finished without performing the cleaning processing.

However, if the detection means for the main body only determines whether the body is seated or separated, there is a risk that automatic cleaning will not be achieved during male urination. Therefore, a process corresponding to automatic washing of male standing urine will be described with reference to FIGS.
FIG. 13 is a flowchart showing a process for determining the washing mode corresponding to the male standing urine according to the embodiment. Most of FIG. 13 is the same as the flowchart of FIG. 11 is the same as FIG. 11, and the description of the processing is omitted depending on necessity.

  The flowchart of FIG. 13 will be described below. In S2000, it is determined whether or not the remote control determination means has confirmed the hand-holding detection. When No in S2000, S2030 is executed. The processing when S2000 is Yes is the same as FIG. In S2030, it is determined whether or not the main body detection means is detecting the toilet front. The detection in front of the toilet means that the user is staying in front of the toilet, that is, the state of male standing urine. In addition, a state in which the reflection level of the light receiving unit of the main body is further lower than that during detection in front of the toilet is set as a non-detection state without a user. (As shown in FIG. 7)

When the main body detection means is detecting in front of the toilet bowl (Yes in S2030), the cleaning mode determination process is terminated. When the main body detection means is not being detected in front of the toilet bowl (No in S2030), the process proceeds to S2001. Since the processing after S2001 is the same as that in FIG. 11, the detailed description is omitted. That is, the automatic cleaning prohibition mode is not reached when the front of the toilet is being detected, so that the automatic cleaning does not stop when the male urinates. In addition, since the seating is being detected during cleaning and the automatic cleaning prohibition mode is reached according to the detection state of the determination means for the remote controller, there is no adverse effect due to the addition of S2030.
Further, the determination processing of S3001 in FIG. 12 is assumed to detect whether the main body detection means is detecting from before the toilet bowl (not shown). That is, it is determined whether the user has left the toilet, and automatic cleaning is performed when the user leaves. With this process, automatic cleaning is not prohibited even when a man is standing, and automatic cleaning can be performed when the user leaves.

With this process, it is possible to provide a toilet cleaning device that can automatically enter the automatic cleaning prohibition mode without requiring the user to perform a special operation.
